| Utility of the 2019 EULAR/ACR SLE classification criteria for predicting mortality and hospitalisation: development and cross-validation of ominosity score
Figueroa-Parra G , Hanson AC , Sanchez-Rodriguez A , Meade-Aguilar JA , González-Treviño M , Cuéllar-Gutiérrez MC , Barbour KE , Duarte-García A , Crowson C . RMD Open 2024 10 (4) OBJECTIVE: The 2019 European Alliance of Associations for Rheumatology (EULAR)/American College of Rheumatology (ACR) systemic lupus erythematosus (SLE) classification criteria score (≥20 points) has been associated with poor outcomes. We aimed to evaluate its utility as a predictor for mortality and hospitalisation and to derive and validate an ominosity score based on the SLE classification criteria set. METHODS: Incident patients with SLE in a population-based cohort were included. The association between the 2019 EULAR/ACR SLE score and mortality and hospitalisation was assessed using Cox regression adjusted for age, sex and calendar year. An ominosity score for mortality was developed based on the SLE criteria set. The least absolute shrinkage and selection operator method was used to estimate model coefficients. Concordance and calibration were assessed by cross-validation and by plotting the observed event rates against the deciles of predicted probabilities. RESULTS: Among 374 patients with incident SLE, a EULAR/ACR score ≥20 points was not associated with an increased risk of mortality (HR 1.17, 95% CI 0.67 to 2.03) or first hospitalisation (HR 1.14, 95% CI 0.79 to 1.64) compared with a score ≤19 points. The derived ominosity score for mortality included age, sex, thrombocytopaenia, neuropsychiatric manifestations, subacute cutaneous or discoid lupus, non-scarring alopecia, inflammatory arthritis, renal involvement, antiphospholipid antibodies and hypocomplementaemia. This model demonstrated a concordance=0.76 with adequate calibration. Age and sex were the main predictors, as seen in the model including just age, sex and year (concordance=0.77). CONCLUSION: The 2019 EULAR/ACR SLE criteria score was not associated with mortality and hospitalisation. The derived ominosity score for mortality presented good prediction for mortality but was not better than age and sex alone. |
| Respiratory function and evaluation in individuals with facioscapulohumeral muscular dystrophy in the Muscular Dystrophy Surveillance, Tracking and Research Network
Mathews KD , Suhl J , Conway KM , Moore A , Alese JT , Butterfield RJ , Romitti PA . Neuromuscul Disord 2024 46 105240 Using data from the US population-based, multisite Muscular Dystrophy Surveillance, Tracking, and Research Network (MD STARnet), we describe respiratory testing and insufficiency among people with facioscapulohumeral muscular dystrophy (FSHD) diagnosed during 2008-2016. We calculated frequencies and proportions for selected outpatient respiratory assessments (pulmonary function tests [PFTs], forced vital capacity (FVC), inspiratory/expiratory pressure, and polysomnograms) and abnormal test results. We examined frequencies by disease characteristics (FSHD type, ages of onset, non-ambulatory status, scoliosis, lordosis), obesity, and number of health encounters. Of 170 people with FSHD, 20.0% underwent PFTs during 2008-2016. Polysomnograms were infrequent (14.1%). FVC <80% predicted was recorded for 64.7% of people tested; additional respiratory outcomes were rare (<5%). Frequency of evaluations and respiratory insufficiency were higher among those with known risk factors and longer follow-up. We observed low proportions of respiratory testing among all confirmed cases of FSHD, but relatively high proportions of mild respiratory insufficiency among those tested. The higher proportions of testing among people with conditions that increase risk of respiratory complications suggest targeted monitoring. Broad implementation of the FSHD guidelines recommending all individuals receive baseline respiratory evaluation at diagnosis could identify respiratory insufficiency as a complication of FSHD. |

J Travel Med 2024 31 (5) BACKGROUND: On 20 September 2022, the Ugandan Ministry of Health declared an outbreak of Ebola disease caused by Sudan ebolavirus. METHODS: From 6 October 2022 to 10 January 2023, Centers for Disease Control and Prevention (CDC) staff conducted public health assessments at five US ports of entry for travellers identified as having been in Uganda in the past 21 days. CDC also recommended that state, local and territorial health departments ('health departments') conduct post-arrival monitoring of these travellers. CDC provided traveller contact information, daily to 58 health departments, and collected health department data regarding monitoring outcomes. RESULTS: Among 11 583 travellers screened, 132 (1%) required additional assessment due to potential exposures or symptoms of concern. Fifty-three (91%) health departments reported receiving traveller data from CDC for 10 114 (87%) travellers, of whom 8499 (84%) were contacted for monitoring, 1547 (15%) could not be contacted and 68 (1%) had no reported outcomes. No travellers with high-risk exposures or Ebola disease were identified. CONCLUSION: Entry risk assessment and post-arrival monitoring of travellers are resource-intensive activities that had low demonstrated yield during this and previous outbreaks. The efficiency of future responses could be improved by incorporating an assessment of risk of importation of disease, accounting for individual travellers' potential for exposure, and expanded use of methods that reduce burden to federal agencies, health departments, and travellers. |

| Effects of COVID-19, control measures, and program adaptation on prevention of mother-to-child HIV transmission service uptake in Central Region, Uganda
Nakakande J , Daama A , Komakech H , Bwanika C , Senyimba C , Namukanja P , Kisaakye LN , Namatovu J , Kagaayi J . BMC Public Health 2024 24 (1) 3142 BACKGROUND: Coronavirus disease 2019 (COVID-19) control measures presented impediments for prevention of mother-to-child transmission of HIV (PMTCT) programming in Uganda. Nationwide control measures implemented April-June 2020 included a public transport ban and mandatory travel permits for pregnant women to access clinics. Program adaptations instituted for continuity of services included community drug delivery and home-based DNA-PCR testing for HIV-exposed infants (HEI). We examined the effect of COVID-19 control measures and program adaptations on PMTCT service uptake in central Uganda. METHODS: We analysed data for pregnant women living with HIV (WLHIV) and HEI receiving PMTCT services in eight districts in central Uganda. We abstracted data from medical records at 96 public clinics for six months pre-lockdown (October 2019-March 2020), three months of lockdown (April-June 2020), and six months post-lockdown (July-December 2020). We measured monthly antiretroviral therapy (ART) refill attendance, health facility deliveries, and timely DNA-PCR testing of HEI for HIV (within two months of birth). We conducted segmented ordinary least squares regression of interrupted time series and adjusted for month-to-month changes using Cumby-Huizinga test. We reported results using coefficients and 95% confidence intervals (CIs). RESULTS: At the start of pre-lockdown (October 2019), there were 448 deliveries, 2,676 ART refills and 556 timely HEI tests. The pre-lockdown trend for ART refills increased while deliveries and HEI tests declined. At the start of lockdown (April 2020), all indicators declined, although significantly for facility deliveries (-60; 95% CI: -102, -18). Lockdown monthly trends were positive with 68 more HEI tested per month (95% CI:42, 93) and 51 more deliveries (95% CI: 9, 94) but insignificantly negative for ART refills. At start of post-lockdown (July 2020), HEI testing declined (-28; 95%CI: -48, -8). Post-lockdown HEI testing trend was negative with 70 fewer HEI tested per month (95%CI: -79, -62) while no difference in trend for deliveries and ART refills. CONCLUSION: COVID-19 control measures had a significant immediate negative impact on pregnancy deliveries at health facilities. During lockdown, all service rates rapidly recovered through program adaptations, significantly for HEI testing and deliveries. Maintaining these adaptations might help restore the positive trend in timely HIV testing for HEI. |
| Epidemiology and response to the COVID-19 pandemic in the Dadaab Refugee Camp Complex, Kenya, March 2020-December 2022
Ope M , Musyoka R , Kosar A , Osman M , Hassan A , Mohammed H , Munyua P , Juma B , Hunsperger E , Mohammed S , Burton J , Eidex RB . Travel Med Infect Dis 2024 63 102785 INTRODUCTION: Refugee settings may increase the risk of SARS-CoV-2 infection and death, yet data on the response to the pandemic in these populations is scarce. METHODS: We describe interventions to mitigate SARS-CoV-2 transmission in Dadaab Refugee Camp Complex, Kenya and performed descriptive analyses using March 2020 to December 2022 data from Kenya's national SARS-CoV-2 repository and line list of positive cases maintained by United Nations High Commissioner for Refugees (UNHCR). We calculated case fatality rates (CFR) and attack rates per 100,000 (AR) using the 2019 national census and population statistics from UNHCR and compared them to national figures. RESULTS: SARS-CoV-2 infection was first reported in April and May 2020, among host community members and refugees respectively. Of 964 laboratory-confirmed cases, 700 (72.6 %) were refugees. The AR was 82.7 (95 % CI 72.6-92.8) for host community members, 228.3 (95 % CI 211.3-245.4) for refugees and 721.1 (95 % CI 718.7-723.5) nationally. The CFR was 1.5 % (95 % CI 0.15-3.18) for host community members, 1.76 % (95 % CI 1.71-1.80) nationally and 7.4 % (95 % CI 5.4-9.4) for refugees. Mitigation measures implemented by the Government of Kenya, UNHCR and partners during the pandemic included multisectoral coordination, movement restrictions, mass gathering bans, and health promotion. Social distancing, symptom screening and mandatory mask usage were enforced during mass gatherings. Testing capacity was bolstered, quarantine and isolation facilities established, and vaccination initiated. CONCLUSIONS: Despite a low AR and UNHCR's swift and comprehensive response, refugees' CFR was high, underscoring their vulnerability and need for targeted interventions during epidemic responses. |

MMWR Morb Mortal Wkly Rep 2024 73 (47) 1082-1086 Oral pre-exposure prophylaxis (PrEP) reduces HIV acquisition risk from sex by 99% and from injection drug use by ≥74% when used as recommended. The Joint United Nations Programme on HIV/AIDS (UNAIDS) has set a goal of 21.2 million persons using (initiating or continuing) PrEP globally in 2025. In 2016, CDC, with the U.S. President's Emergency Plan for AIDS Relief, joined ministries of health to implement PrEP globally. PrEP is beneficial for persons at substantial risk for acquiring HIV, including but not limited to key populations, which include female sex workers, men who have sex with men, persons in prisons and other enclosed settings, persons who inject drugs, and transgender persons. Annual country targets were used to guide scale-up. In 2023, CDC supported 856,816 PrEP initiations, which represents nearly one quarter of the 3.5 million persons globally who either initiated or continued PrEP that year. During 2017-2023, CDC supported PrEP initiations for 2,278,743 persons, 96.0% of whom were in sub-Saharan Africa. More than one half (64.0%) were female and 44.9% were aged 15-24 years. Overall, CDC achieved 118.7% of its PrEP initiation targets for the 7-year period. Among PrEP initiations for key populations, the majority in sub-Saharan Africa were female sex workers, whereas in Southeast Asia, Eurasia, and the Americas, the majority were men who have sex with men. Continued rapid scale-up is needed to meet the UNAIDS goal to end HIV as a public health threat. |
| Detection of real-time changes in direction of COVID-19 transmission using national- and state-level epidemic trends based on R(t) estimates - United States Overall and New Mexico, April-October 2024

MMWR Morb Mortal Wkly Rep 2024 73 (46) 1058-1063 Public health practitioners rely on timely surveillance data for planning and decision-making; however, surveillance data are often subject to delays. Epidemic trend categories, based on time-varying effective reproductive number (R(t)) estimates that use nowcasting methods, can mitigate reporting lags in surveillance data and detect changes in community transmission before reporting is completed. CDC analyzed the performance of epidemic trend categories for COVID-19 during summer 2024 in the United States and at the state level in New Mexico. COVID-19 epidemic trend categories were estimated and released in real time based on preliminary data, then retrospectively compared with final emergency department (ED) visit data to determine their ability to detect or confirm real-time changes in subsequent ED visits. Across the United States and in New Mexico, epidemic trend categories were an early indicator of increases in COVID-19 community transmission, signifying increases in COVID-19 community transmission in May, and a confirmatory indicator that decreasing COVID-19 ED visits reflected actual decreases in COVID-19 community transmission in September, rather than incomplete reporting. Public health decision-makers can use epidemic trend categories, in combination with other surveillance indicators, to understand whether COVID-19 community transmission and subsequent ED visits are increasing, decreasing, or not changing; this information can guide communications decisions. |
| Antiviral development for the polio endgame: Current progress and future directions
Xie H , Rhoden EE , Liu HM , Ogunsemowo F , Mainou BA , Burke RM , Burns CC . Pathogens 2024 13 (11) As the world is approaching the eradication of wild poliovirus serotype 1, the last of the three wild types, the question of how to maintain a polio-free world becomes imminent. To mitigate the risk of sporadic vaccine-associated paralytic polio (VAPP) caused by oral polio vaccines (OPVs) that are routinely used in global immunization programs, the Polio Antivirals Initiative (PAI) was established in 2006. The primary goal of the PAI is to facilitate the discovery and development of antiviral drugs to stop the excretion of immunodeficiency-associated vaccine-derived poliovirus (iVDPV) in B cell-deficient individuals. This review summarizes the major progress that has been made in the development of safe and effective poliovirus antivirals and highlights the candidates that have shown promising results in vitro, in vivo, and in clinical trials. |
| The role of simulation science in public health at the Agency for Toxic Substances and Disease Registry: An overview and analysis of the last decade
Desai S , Wilson J , Ji C , Sautner J , Prussia AJ , Demchuk E , Mumtaz MM , Ruiz P . Toxics 2024 12 (11)
Environmental exposures are ubiquitous and play a significant, and sometimes understated, role in public health as they can lead to the development of various chronic and infectious diseases. In an ideal world, there would be sufficient experimental data to determine the health effects of exposure to priority environmental contaminants. However, this is not the case, as emerging chemicals are continuously added to this list, furthering the data gaps. Recently, simulation science has evolved and can provide appropriate solutions using a multitude of computational methods and tools. In its quest to protect communities across the country from environmental health threats, ATSDR employs a variety of simulation science tools such as Physiologically Based Pharmacokinetic (PBPK) modeling, Quantitative Structure-Activity Relationship (QSAR) modeling, and benchmark dose (BMD) modeling, among others. ATSDR's use of such tools has enabled the agency to evaluate exposures in a timely, efficient, and effective manner. ATSDR's work in simulation science has also had a notable impact beyond the agency, as evidenced by external researchers' widespread appraisal and adaptation of the agency's methodology. ATSDR continues to advance simulation science tools and their applications by collaborating with researchers within and outside the agency, including other federal/state agencies, NGOs, the private sector, and academia. |

Int J Environ Res Public Health 2024 21 (11) Hurricane Ida, a Category 4 hurricane, made landfall in southern Louisiana in August of 2021, causing widespread wind damage and flooding. The objective of this study was to investigate knowledge, attitudes, and practices related to post-hurricane mold exposure and cleanup among residents and workers in areas of Louisiana affected by Hurricane Ida and assess changes in knowledge, attitudes, and practices that have occurred over the past 16 years since Hurricane Katrina. We conducted in-person interviews with 238 residents and 68 mold-remediation workers in areas in and around New Orleans to ask about their mold cleanup knowledge and practices, personal protective equipment use, and risk perceptions related to mold. Knowledge of recommended safety measures increased since the post-Katrina survey but adherence to recommended safety measures did not. Many residents and some workers reported using insufficient personal protective equipment when cleaning up mold despite awareness of the potential negative health effects of mold exposure. |
| Evaluating Senegal's COVID-19 surveillance system for early detection and response: lessons from the Keur Massar district, March 03, 2020 to May 31, 2022
Ba A , Loko Roka J , Ndiaye M , Ba MS , Diop B , Pasi O . BMC Public Health 2024 24 (1) 3246 BACKGROUND: The COVID-19 pandemic highlights the importance of strong surveillance systems in detecting and responding to public health threats. We sought to evaluate attributes of Keur Massar district's existing COVID-19 surveillance system. METHOD: A descriptive, cross-sectional study was conducted in June 2022; desk review covered data collected from March 03, 2020 to May 31, 2022 in 18 health posts. Data were collected using a standardized questionnaire completed during a face-to-face interview and a desk review of surveillance data gathered from different notification platforms (Excel, ODK, DHIS2 aggregated, and tracker). Study was conducted in Keur Massar department, in the Dakar region. We conducted face-to-face interviews with 18 nurses in June 2022. We utilized a standardized, semi-structured questionnaire adapted from CDC guidelines for surveillance evaluation. RESULTS: All 18 head nurses targeted, responded to the questionnaire, with an average age of 41.5 years and 63% aged between 30 and 44. The sex ratio (M/F) was 0.6, and respondents had an average of 15.1 years of experience. All nurses were involved in COVID-19 surveillance and had notified at least one suspected case. While 39% conducted COVID-19 data analysis, 55.6% received feedback from the national level. The usefulness score for the surveillance system was 77.7, with the lowest score (72.9) related to describing the pandemic's magnitude. Simplicity scored 63.3, with low scores for the availability of guidelines (0) but high scores for training and equipment (94.4). Acceptability scored 76.6, with strong support for COVID-19 surveillance but weak community involvement (48.6). While no cases were reported through the DHIS2 aggregated platform, 1327 PCR-positive SARS-CoV-2 cases were reported through the national Excel sheet and 278 PCR-positive cases were reported through the COVID-19 DHIS2 tracker during the same period. Timeliness varied, averaging 3 days using ODK and 7 days with the national Excel sheet, with a combined average of 5 days across both systems. CONCLUSION: The study highlights challenges in COVID-19 surveillance due to limited human resources, multiple data systems, and delays in notification. While most nurses were trained and equipped, gaps in data quality, timeliness, and community support emphasize the need for streamlined processes and increased workforce capacity. |
| Optimizing identification of Lyme disease diagnoses in commercial insurance claims data, United States, 2016-2019
Nawrocki CC , Earley AR , Hook SA , Hinckley AF , Kugeler KJ . BMC Infect Dis 2024 24 (1) 1322 BACKGROUND: Commercial insurance claims data are a stable and consistent source of information on Lyme disease diagnoses in the United States and can contribute to our understanding of overall disease burden and the tracking of epidemiological trends. Algorithms consisting of diagnosis codes and antimicrobial treatment information have been used to identify Lyme disease diagnoses in claims data, but there might be opportunity to improve their accuracy. METHODS: We developed three modified versions of our existing claims-based Lyme disease algorithm; each reflected refined criteria regarding antimicrobials prescribed and/or maximum days between diagnosis code and qualifying prescription claim. We applied each to a large national commercial claims database to identify Lyme disease diagnoses during 2016-2019. We then compared characteristics of Lyme disease diagnoses identified by each of the modified algorithms to those identified by our original algorithm to assess differences from expected trends in demographics, seasonality, and geography. RESULTS: Observed differences in characteristics of patients with diagnoses identified by the three modified algorithms and our original algorithm were minimal, and differences in age and sex, in particular, were small enough that they could have been due to chance. However, one modified algorithm resulted in proportionally more diagnoses in men, during peak summer months, and in high-incidence jurisdictions, more closely reflecting epidemiological trends documented through public health surveillance. This algorithm limited treatment to only first-line recommended antimicrobials and shortened the timeframe between a Lyme disease diagnosis code and qualifying prescription claim. CONCLUSIONS: As compared to our original algorithm, a modified algorithm that limits the antimicrobials prescribed and shortens the timeframe between a diagnosis code and a qualifying prescription claim might more accurately identify Lyme disease diagnoses when utilizing insurance claims data for supplementary, routine identification and monitoring of Lyme disease diagnoses. |

In 2022, the U.S. Food and Drug Administration (FDA), the Centers for Disease Control and Prevention (CDC), U.S. state and local partners, the Public Health Agency of Canada (PHAC), and the Canadian Food Inspection Agency (CFIA), conducted a bi-national sample-initiated retrospective outbreak investigation (SIROI) of Listeria monocytogenes illnesses linked to enoki mushrooms. The FDA and CDC investigated the first known L. monocytogenes outbreak linked to enoki mushrooms from 2016-2020, making the 2022 outbreak the second time this pathogen-commodity pair was investigated by FDA and CDC. The 2022 outbreak included six ill people, all of whom were hospitalized. Epidemiologic, laboratory, and traceback evidence led to multiple public health actions, including voluntary recalls by firms, public communications about the outbreak, and FDA's country-wide Import Alert for enoki mushrooms from China. This SIROI illustrates the importance of surveillance sampling, national and international coordination of efforts, and rapid information sharing to identify and stop foodborne outbreaks on a global scale. To reduce the risk of listeriosis illnesses linked to contaminated enoki mushrooms, public health and regulatory agencies in the United States and Canada remain committed to conducting comprehensive surveillance for Listeria in foods and in people, efficiently investigating identified outbreaks, and implementing control measures to potentially minimize the impact of future outbreaks. |
| Demographic characteristics and county-level indicators of social vulnerability in salmonellosis outbreaks linked to ground beef- United States, 2012-2018
Waltenburg MA , Salah Z , Canning M , McCain K , Rickless D , Ablan M , Crawford TN , Sheau Fong Low M , Robyn M , Angelique MMolinari N , Marshall KE . J Food Prot 2024 100411 Ground beef is a common source of US Salmonella illnesses and outbreaks. However, the demographic and socioeconomic factors that are related to risk in ground beef-associated outbreaks of Salmonella infections are poorly understood. We describe the individual-level demographic characteristics and county-level indicators of social vulnerability for people infected with Salmonella linked to outbreaks associated with ground beef in the United States during 2012-2018. Non-Hispanic (NH) White and NH American Indian/Alaska Native persons, and people living in non-metropolitan areas, were overrepresented among people in salmonellosis outbreaks linked to ground beef. Case patients disproportionately resided in counties with high social vulnerability, suggesting that one or more community social risk factors may contribute to or be associated with some food safety risks. Collecting and analyzing socioeconomic and demographic characteristics of people in outbreaks can help identify disparities in foodborne disease, which can be further characterized and inform equity-focused interventions. |
| Analysis of powassan virus genome sequences from human cases reveals substantial genetic diversity with implications for molecular assay development

Powassan virus (POWV) is an emerging tick-borne virus that causes severe meningoencephalitis in the United States, Canada, and Russia. Serology is generally the preferred diagnostic modality, but PCR on cerebrospinal fluid, blood, or urine has an important role, particularly in immunocompromised patients who are unable to mount a serologic response. Although the perceived poor sensitivity of PCR in the general population may be due to the biology of infection and health-seeking behavior (with short viremic periods that end before hospital presentation), limitations in assay design may also contribute. Genome sequences from clinical POWV cases are extremely scarce; PCR assay design has been informed by those available, but the numbers are limited. Larger numbers of genome sequences from tick-derived POWV are available, but it is not known if POWV genomes from human infections broadly mirror genomes from tick hosts, or if human infections are caused by a subset of more virulent strains. We obtained viral genomic data from 10 previously unpublished POWV human infections and showed that they broadly mirror the diversity of genome sequences seen in ticks, including all three major clades (lineage I, lineage II Northeast, and lineage II Midwest). These newly published clinical POWV genome sequences include the first confirmed lineage I infection in the United States, highlighting the relevance of all clades in human disease. An in silico analysis of published POWV PCR assays shows that many assays were optimized against a single clade and have mismatches that may affect their sensitivity when applied across clades. This analysis serves as a launching point for improved PCR design for clinical diagnostics and environmental surveillance. |

IJID Regions 2024 13 Objectives: Yellow fever (YF) remains a public health threat in Sub-Saharan Africa and South America, with an estimated 200,000 cases and 30,000 deaths annually. Although the World Health Organization considers Tanzania to be at low risk for YF because no YF cases have been reported, the country remains at alert to importation of the virus due to ecological factors and high connectivity to high-risk YF areas in other countries. This study aimed to identify points of interest with connectivity to high-risk YF areas to guide preparedness efforts in Tanzania. Methods: Using the Population Connectivity Across Borders (PopCAB) toolkit, the Nelson Mandela African Institution of Science and Technology (Department of Health and Biomedical Sciences), in collaboration with the Tanzania Ministry of Health and the Centers for Disease Control and Prevention, implemented 12 focus group discussions with participatory mapping in two high-risk borders of Mutukula and Namanga. Results: Participants identified 147 and 90 points of interest with connectivity to YF risk areas in Kenya and Uganda, respectively. The identified locations are important for trade, fishing, pastoralism, tourism, health-seeking, agriculture, mining, religious activities, education, and cross-border marriages. Conclusions: The Tanzania Ministry of Health used the results to update cross-border surveillance and risk communication strategies and vaccination guidelines to prevent the importation of YF into Tanzania. © 2024 The Authors |
| Faith-based messaging and materials for colorectal cancer screening in the United States: Application of boot camp translation within the African Methodist Episcopal Church
Thompson J , Gautom P , Rivelli J , Johnson C , Burns M , Levell C , Hayes N , Coronado G . J Relig Health 2024 The Black Church has long been an institution of refuge, mobilization, and healing in Black or African American communities. While health promotion interventions have been implemented in the Black Church, little is known about ways to incorporate faith into colorectal cancer (CRC) screening messages. Using modified boot camp translation, a community-based approach, we met with 27 members of the African Methodist Episcopal Church in Atlanta, Georgia, for in-person and virtual sessions to co-create faith-based CRC screening messages and identify channels for sharing information within the church community. Examples of messages developed included "Faith over fear" and "Honor God by taking care of your body." Identified dissemination channels included Sunday service, community events, and social media. Churches serve as key partners in delivering health information, as they are among the most trusted institutions within the Black or African American community. |
| Cost-effectiveness of Nirsevimab for respiratory syncytial virus in infants and young children
Hutton DW , Prosser LA , Rose AM , Mercon K , Ortega-Sanchez IR , Leidner AJ , McMorrow ML , Fleming-Dutra KE , Prill MM , Pike J , Jones JM . Pediatrics 2024 BACKGROUND AND OBJECTIVES: Respiratory syncytial virus (RSV) causes substantial hospitalization in US infants. The Advisory Committee on Immunization Practices recommended nirsevimab in infants younger than 8 months born during or entering their first RSV season and for children aged 8 to 19 months at increased risk of RSV hospitalization in their second season. This study's objective was to evaluate the cost-effectiveness of nirsevimab in all infants in their first RSV season and in high-risk children in their second season. METHODS: We simulated healthcare utilization and deaths from RSV with and without nirsevimab among infants aged 0 to 7 months and those 8 to 19 months old over a single RSV season. Data came from published literature, US Food and Drug Administration approval documents, and epidemiologic surveillance data. We evaluated societal outcomes over a lifetime discounting at 3% and reporting in 2022 US dollars. Sensitivity and scenario analyses identified influential variables. RESULTS: We estimated that 107 253 outpatient visits, 38 204 emergency department visits, and 14 341 hospitalizations could be averted each year if half of the US birth cohort receives nirsevimab. This would cost $153 517 per quality-adjusted life year (QALY) saved. Nirsevimab in the second season for children facing a 10-fold higher risk of hospitalization would cost $308 468 per QALY saved. Sensitivity analyses showed RSV hospitalization costs, nirsevimab cost, and QALYs lost from RSV disease were the most influential parameters with cost-effectiveness ratios between cost-saving and $323 788 per QALY saved. CONCLUSIONS: Nirsevimab for infants may be cost-effective, particularly among those with higher risks and costs of RSV. |
| Cost-effectiveness of maternal vaccination to prevent respiratory syncytial virus illness
Hutton DW , Prosser LA , Rose AM , Mercon K , Ortega-Sanchez IR , Leidner AJ , McMorrow ML , Fleming-Dutra KE , Prill MM , Pike J , Jones JM . Pediatrics 2024 BACKGROUND AND OBJECTIVES: Respiratory syncytial virus (RSV) commonly causes hospitalization among US infants. A maternal vaccine preventing RSV in infants, RSV bivalent prefusion F maternal vaccine (RSVpreF), was approved by the US Food and Drug Administration and recommended by the Advisory Committee on Immunization Practices. Our objective was to evaluate the health benefits and cost-effectiveness of vaccinating pregnant persons in the United States using RSVpreF. METHODS: We simulated RSV infection and disease with and without seasonal RSVpreF vaccination in half of the pregnant persons in the annual US birth cohort during weeks 32 through 36 of gestation. Model inputs came from peer-reviewed literature, Food and Drug Administration records, and epidemiological surveillance databases. The results are reported using a societal perspective in 2022 US dollars for a 1-year time frame, discounting future health outcomes and costs at 3%. Sensitivity and scenario analyses were performed. RESULTS: Year-round maternal vaccination with RSVpreF would prevent 45 693 outpatient visits, 15 866 ED visits, and 7571 hospitalizations among infants each year. Vaccination had a societal incremental cost of $396 280 per quality-adjusted life-year (QALY) saved. Vaccination from September through January cost $163 513 per QALY saved. The most influential inputs were QALYs lost from RSV disease, the cost of the vaccine, and RSV-associated hospitalization costs; changes in these inputs yielded outcomes ranging from cost-saving to $800 000 per QALY saved. CONCLUSIONS: Seasonal maternal RSV vaccination designed to prevent RSV lower respiratory tract infection in infants may be cost-effective, particularly if administered to pregnant persons immediately before or at the beginning of the RSV season. |
| Cost-effectiveness of extending human papillomavirus vaccination to population subgroups older than 26 years who are at higher risk for human papillomavirus infection in the United States
Laprise JF , Chesson HW , Markowitz LE , Drolet M , Brisson M . Ann Intern Med 2024 BACKGROUND: In June 2019, the U.S. Advisory Committee on Immunization Practices recommended shared clinical decision making regarding potential human papillomavirus (HPV) vaccination of men and women aged 27 to 45 years ("mid-adults"). OBJECTIVE: To examine the incremental cost-effectiveness ratios (ICERs) and number needed to vaccinate (NNV) to prevent 1 HPV-related cancer case of expanding HPV vaccination to subgroups of mid-adults at increased risk for HPV-related diseases in the United States. DESIGN: Individual-based transmission dynamic modeling of HPV transmission and associated diseases using HPV-ADVISE (Agent-based Dynamic model for VaccInation and Screening Evaluation). DATA SOURCES: Published data. TARGET POPULATION: All U.S. mid-adults and higher-risk subgroups within this population. TIME HORIZON: 100 years. PERSPECTIVE: Health care sector. INTERVENTION: Expanding 9-valent HPV vaccination to mid-adults and higher-risk subgroups. OUTCOME MEASURES: ICERs and NNVs. RESULTS OF BASE-CASE ANALYSIS: Expanding 9-valent HPV vaccination to all mid-adults, those with more lifetime partners, and those who have just separated was projected to cost an additional $2 005 000, $763 000, and $1 164 000 per quality-adjusted life-year (QALY) gained, respectively. The NNVs to prevent 1 additional HPV-related cancer case were 7670, 3190, and 5150, respectively, compared with 223 for vaccination of persons aged 9 to 26 years (vs. no vaccination). RESULTS OF SENSITIVITY ANALYSIS: The mid-adult strategy with the lowest ICER and NNV was vaccinating infrequently screened mid-adult women who have just separated and have a higher number of lifetime sex partners (ICER, $86 000 per QALY gained; NNV, 470). LIMITATION: Uncertainty about rate of new sex partners and natural history of HPV among mid-adults. CONCLUSION: Vaccination of mid-adults against HPV is substantially less cost-effective and produces higher NNVs than vaccination of persons younger than 26 years under all scenarios investigated. However, cost-effectiveness and NNV are projected to improve when higher-risk mid-adult subgroups are vaccinated, such as mid-adults with more sex partners and who have recently separated, and women who are underscreened.

| The costs and cost-effectiveness of a two-dose oral cholera vaccination campaign: A case study in a refugee camp setting in Thailand
Wallace AS , Date K , Pallas SW , Wongjindanon N , Phares CR , Abimbola T . Vaccines (Basel) 2024 12 (11) Oral cholera vaccination (OCV) campaigns are increasingly used to prevent cholera outbreaks; however, little is known about their cost-effectiveness in refugee camps. We conducted a cost-effectiveness analysis of a pre-emptive OCV campaign in the Maela refugee camp in Thailand, where outbreaks occurred with an annual incidence rate (IR) of up to 10.7 cases per 1000. Data were collected via health sector records and interviews and household interviews. In the base-case scenario comparing the OCV campaign with no campaign, we estimated the campaign effect on the cholera IR and case fatality rate (CFR: 0.09%) from a static cohort model and calculated incremental cost-effectiveness ratios for the outcomes of death, disability-adjusted life-years (DALYs), and cases averted. In sensitivity analyses, we varied the CFR and IR. The household economic cost of illness was USD 21, and the health sector economic cost of illness was USD 51 per case. The OCV campaign economic cost was USD 289,561, 42% attributable to vaccine costs and 58% to service delivery costs. In our base case, the incremental cost was USD 1.9 million per death averted, USD 1745 per case averted, and USD 69,892 per DALY averted. Sensitivity analyses that increased the CFR to 0.35% or the IR to 10.4 cases per 1000 resulted in a cost per DALY of USD 15,666. The low multi-year average CFR and incidence of the cholera outbreaks in the Maela camp were key factors associated with the high cost per DALY averted. However, the sensitivity analyses indicated higher cost-effectiveness in a setting with a higher CFR or cholera incidence, indicating when to consider campaign use to reduce the outbreak risk. |

JAMA Netw Open 2024 7 (11) e2448003 IMPORTANCE: Seasonal influenza is associated with substantial disease burden. The relationship between census tract-based social vulnerability and clinical outcomes among patients with influenza remains unknown. OBJECTIVE: To characterize associations between social vulnerability and outcomes among patients hospitalized with influenza and to evaluate seasonal influenza vaccine and influenza antiviral utilization patterns across levels of social vulnerability. DESIGN, SETTING, AND PARTICIPANTS: This retrospective repeated cross-sectional study was conducted among adults with laboratory-confirmed influenza-associated hospitalizations from the 2014 to 2015 through the 2018 to 2019 influenza seasons. Data were from a population-based surveillance network of counties within 13 states. Data analysis was conducted in December 2023. EXPOSURE: Census tract-based social vulnerability. MAIN OUTCOMES AND MEASURES: Associations between census tract-based social vulnerability and influenza outcomes (intensive care unit admission, invasive mechanical ventilation and/or extracorporeal membrane oxygenation support, and 30-day mortality) were estimated using modified Poisson regression as adjusted prevalence ratios. Seasonal influenza vaccine and influenza antiviral utilization were also characterized across levels of social vulnerability. RESULTS: Among 57 964 sampled cases, the median (IQR) age was 71 (58-82) years; 55.5% (95% CI, 51.5%-56.0%) were female; 5.2% (5.0%-5.4%) were Asian or Pacific Islander, 18.3% (95% CI, 18.0%-18.6%) were Black or African American, and 64.6% (95% CI, 64.2%-65.0%) were White; and 6.6% (95% CI, 6.4%-68%) were Hispanic or Latino and 74.7% (95% CI, 74.3%-75.0%) were non-Hispanic or Latino. High social vulnerability was associated with higher prevalence of invasive mechanical ventilation and/or extracorporeal membrane oxygenation support (931 of 13 563 unweighted cases; adjusted prevalence ratio [aPR], 1.25 [95% CI, 1.13-1.39]), primarily due to socioeconomic status (790 of 11 255; aPR, 1.31 [95% CI, 1.17-1.47]) and household composition and disability (773 of 11 256; aPR, 1.20 [95% CI, 1.09-1.32]). Vaccination status, presence of underlying medical conditions, and respiratory symptoms partially mediated all significant associations. As social vulnerability increased, the proportion of patients receiving seasonal influenza vaccination declined (-19.4% relative change across quartiles; P < .001) as did the proportion vaccinated by October 31 (-6.8%; P < .001). No differences based on social vulnerability were found in in-hospital antiviral receipt, but early in-hospital antiviral initiation (-1.0%; P = .01) and prehospital antiviral receipt (-17.3%; P < .001) declined as social vulnerability increased. CONCLUSIONS AND RELEVANCE: In this cross-sectional study, social vulnerability was associated with a modestly increased prevalence of invasive mechanical ventilation and/or extracorporeal membrane oxygenation support among patients hospitalized with influenza. Contributing factors may have included worsened baseline respiratory health and reduced receipt of influenza prevention and prehospital or early in-hospital treatment interventions among persons residing in low socioeconomic areas. |
| Social Determinants of Health and Health-Related Social Needs Among Adults With Chronic Diseases in the United States, Behavioral Risk Factor Surveillance System, 2022
Hacker K , Thomas CW , Zhao G , Claxton JS , Eke P , Town M . Prev Chronic Dis 2024 21 E94 INTRODUCTION: The relationship between social determinants of health (SDOH) and health-related social needs (HRSN) and some chronic diseases at the population level is not well known. We sought to determine relationships between SDOH/HRSN and major chronic diseases among US adults by using data from the 2022 Behavioral Risk Factor Surveillance System (BRFSS). METHODS: We used data from the new Social Determinants and Health Equity (SD/HE) module, conducted in 39 states, the District of Columbia, and 2 territories as part of the 2022 BRFSS. These data yielded a sample of 324,631 adult participants (aged ≥18 y). We examined 12 indicators of SDOH/HRSN and 9 chronic diseases. We calculated weighted prevalence estimates for each SDOH/HRSN measure for each chronic disease and associations between each SDOH/HRSN and each chronic disease. RESULTS: Two-thirds of participants (66.3%) had 1 or more chronic diseases, and 59.4% reported 1 or more adverse SDOH/HRSN. Prevalence estimates for individual SDOH/HRSN measures were generally higher among participants with chronic diseases (except cancer). The more chronic diseases reported, the more likely participants were to have SDOH/HRSN (P < .05 for linear trend). The leading SDOH/HRSN measures associated with each chronic disease varied; however, the most common were mental stress, receiving food stamps or participating in the Supplemental Nutrition Assistance Program, cost as a barrier for needed medical care, and life dissatisfaction. CONCLUSION: From a treatment and prevention perspective, health care providers should consider the influence of SDOH/HRSN on people with or at risk for chronic diseases. Additionally, human service and public health systems in communities with high rates of chronic disease should consider these findings as they plan to mitigate adverse SDOH. |

| Associations between health-related social needs and cardiovascular health among US adults
Zhang Z , Jackson SL , Thompson-Paul AM , Yin X , Merritt RK , Coronado F . J Am Heart Assoc 2024 e035863 BACKGROUND: Unfavorable health-related social needs (HRSNs) have the potential to worsen health and well-being and drive health disparities. Its associations with cardiovascular health (CVH), assessed by Life's Essential 8, have not been comprehensively examined among US adults. METHODS AND RESULTS: We used the National Health and Nutrition Examination Survey 2011 to March 2020 data for adults aged ≥20 years. We grouped Life's Essential 8 scores as low (0-49), moderate (50-79), and high (80-100) CVH. We identified 8 unfavorable HRSNs and assigned a value of 1 for the unfavorable status of each. The number of unfavorable HRSNs was summed and ranged from 0 to 8, with higher numbers indicating more unfavorable HRSNs. We used multivariable linear and multinomial logistic regression to examine the association between HRSNs and CVH. A total of 14 947 participants were included (n=7340 male [49.3%]; mean [SE] age, 46.4 [0.35] years). A higher number of unfavorable HRSNs were associated with worse CVH: comparing adults with unfavorable HRSNs of 1-2, 3-4, and ≥5 to those with none, the fully adjusted prevalence ratios (95% CI) for low CVH were 1.42 (1.17-1.73), 2.11 (1.69-2.63), and 2.42 (1.90-3.08), respectively. The corresponding prevalence ratios (95% CI) for high CVH were 0.77 (0.68-0.87), 0.58 (0.49-0.67), and 0.46 (0.38-0.55). The associations were consistent across subgroups and in sensitivity analyses. CONCLUSIONS: There was a graded association between unfavorable HRSNs and a higher prevalence of low CVH or lower prevalence of high CVH. Public health interventions targeting HRSNs might reduce health disparities and promote CVH. |

Emerg Infect Dis 2024 30 (12) 2467-2475
Bartonella quintana infection can cause severe disease that includes clinical manifestations such as endocarditis, chronic bacteremia, and vasoproliferative lesions of the skin and viscera. B. quintana bacteria is transmitted by the human body louse (Pediculus humanus corporis) and is associated with homelessness and limited access to hygienic services. We report B. quintana infection in 2 kidney transplant recipients in the United States from an organ donor who was experiencing homelessness. One infection manifested atypically, and the other was minimally symptomatic; with rapid detection, both recipients received timely treatment and recovered. B. quintana was identified retrospectively in an archived donor hematoma specimen, confirming the transmission link. Information about the organ donor's housing status was critical to this investigation. Evaluation for B. quintana infection should be considered for solid organ transplant recipients who receive organs from donors with a history of homelessness or of body lice infestation. |
| Homelessness and organ donor-derived Bartonella quintana infection
Henderson R , Mosites E , Koehler JE , Boodman C , Marx GE . Emerg Infect Dis 2024 30 (12) 2459-2466
Louseborne Bartonella quintana infections in the United States occur almost exclusively among persons experiencing homelessness because of inadequate access to hygiene resources. Homelessness is increasing, and persons experiencing homelessness can be organ donors, despite barriers to receiving donated organs themselves. Recent reports have documented B. quintana transmission via organs transplanted from donors who had recently experienced homelessness. Those reports demonstrate the threat of severe bartonellosis in immunosuppressed organ transplant recipients after donor-derived B. quintana infection. Addressing the root causes of B. quintana transmission could improve the quality of life for persons experiencing homelessness and simultaneously mitigate risk for donor-derived B. quintana transmission. Interventions include improved access to housing, consistent access to hot water for showers and laundry, early treatment of body lice infestation and B. quintana infection, and B. quintana testing and prophylactic treatment of recipients of organs from donors who have experienced risk factors for B. quintana, including homelessness. |
| Coccidioidomycosis transmission through solid organ transplantation (2013-2022): A report of the Organ Procurement and Transplantation Network ad hoc Disease Transmission Advisory Committee

Transpl Infect Dis 2024 e14406 BACKGROUND: Coccidioidomycosis is a fungal infection that poses a serious risk when transmitted through organ transplantation. We analyzed cases reported to the Organ Procurement and Transplantation Network ad hoc Disease Transmission Advisory Committee from 2013 to 2022. METHODS: Donors and/or recipients who had positive Coccidioides immitis/posadasii serology, pathology, and/or culture were included in this study. Cases adjudicated as 'proven' or 'probable' were analyzed for donor infection risk factors, the timing of infection, transmission by organ type, clinical manifestations, and recipient outcomes. Patient and facility identifiers were removed prior to review. RESULTS: During this time period, 73 potential instances of Coccidioides donor disease transmission events were reported. Among them, infection was transmitted from seven deceased donors to eight recipients. All seven deceased donors had prior infection or exposure to regions where coccidioidomycosis is endemic. Of 20 individuals receiving organs from these donors, eight developed infection, resulting in a 40% transmission rate. The median time to diagnosis post-transplant was 39 days. Disseminated disease occurred in six recipients, five of whom died from the infection. Notably, none of the recipients who received prophylactic antifungal treatment died from the infection. CONCLUSION: Despite its rarity, donor-derived Coccidioides infection is a serious concern, particularly due to the high mortality rate in the early post-transplant period. To mitigate these risks, a thorough assessment of donor exposure history, coupled with donor serology and bronchoalveolar lavage cultures, can effectively guide post-transplant antifungal prophylaxis. Prompt reporting is crucial to prevent Coccidioides infections among other recipients. |

OBJECTIVES: Trivalent inactivated influenza vaccine effectiveness was low in a prospective cohort of healthcare personnel (HCP) in Israel from 2016 to 2019. We conducted a randomised immunogenicity trial of quadrivalent recombinant influenza vaccine (RIV4) and standard-dose inactivated influenza vaccine (IIV4) among frequently and infrequently vaccinated previous cohort participants. METHODS: From October 2019 to January 2020, we enrolled and randomly allocated HCP from two Israeli hospitals to receive IIV4 or RIV4. Hemagglutination inhibition (HAI) antibody titres against 2019-2020 vaccine reference influenza viruses were compared between vaccine groups using geometric mean titre (GMT) ratios from sera collected one-month post-vaccination and by frequency of vaccination in the past 5 years (>2 vs ≤2). RESULTS: Among 415 HCP, the GMT ratio comparing RIV4 to IIV4 was 2.0 (95% confidence interval [CI] 1.7-2.7) for A(H1N1)pdm09, 1.6 (95% CI: 1.3-1.9) for A(H3N2), 1.8 (95% CI: 1.4-2.2) for B(Yamagata), and 1.1 (95% CI: 0.9-1.4) for B(Victoria). Similarly, RIV4 elicited higher HAI titres than IIV4 against all 2019-2020 vaccine reference viruses except B(Victoria) among infrequently and frequently vaccinated HCP (lower bound of GMT ratio 95% CIs ≥1.0). CONCLUSION: RIV4 had improved immunogenicity for influenza vaccine strains among both infrequent and frequent vaccinees compared to standard-dose IIV4. CLINICAL TRIALS REGISTRATION: NCT04523324. |

IMPORTANCE: Influenza vaccine effectiveness (VE) is commonly assessed against prevention of illness that requires medical attention. Few studies have evaluated VE against secondary influenza infections. OBJECTIVE: To determine the estimated effectiveness of influenza vaccines in preventing secondary infections after influenza was introduced into households. DESIGN, SETTINGS, AND PARTICIPANTS: During 3 consecutive influenza seasons (2017-2020), primary cases (the first household members with laboratory-confirmed influenza) and their household contacts in Tennessee and Wisconsin were enrolled into a prospective case-ascertained household transmission cohort study. Participants collected daily symptom diaries and nasal swabs for up to 7 days. Data were analyzed from September 2022 to February 2024. EXPOSURES: Vaccination history, self-reported and verified through review of medical and registry records. MAIN OUTCOMES AND MEASURES: Specimens were tested using reverse transcription-polymerase chain reaction to determine influenza infection. Longitudinal chain binomial models were used to estimate secondary infection risk and the effectiveness of influenza vaccines in preventing infection among household contacts overall and by virus type and subtype and/or lineage. RESULTS: The analysis included 699 primary cases and 1581 household contacts. The median (IQR) age of the primary cases was 13 (7-38) years, 381 (54.5%) were female, 60 (8.6%) were Hispanic, 46 (6.6%) were non-Hispanic Black, 553 (79.1%) were Non-Hispanic White, and 343 (49.1%) were vaccinated. Among household contacts, the median age was 31 (10-41) years, 833 (52.7%) were female, 116 (7.3%) were Hispanic, 78 (4.9%) were non-Hispanic Black, 1283 (81.2%) were non-Hispanic White, 792 (50.1%) were vaccinated, and 356 (22.5%) had laboratory-confirmed influenza during follow-up. The overall secondary infection risk of influenza among household contacts was 18.8% (95% CI, 15.9% to 22.0%). The risk was highest among children and was 20.3% (95% CI, 16.4% to 24.9%) for influenza A and 15.9% (95% CI, 11.8% to 21.0%) for influenza B. The overall estimated VE for preventing secondary infections among unvaccinated household contacts was 21.0% (95% CI, 1.4% to 36.7%) and varied by type; estimated VE against influenza A was 5.0% (95% CI, -22.3% to 26.3%) and 56.4% (95% CI, 30.1% to 72.8%) against influenza B. CONCLUSIONS AND RELEVANCE: After influenza was introduced into households, the risk of secondary influenza among unvaccinated household contacts was approximately 15% to 20%, and highest among children. Estimated VE varied by influenza type, with demonstrated protection against influenza B virus infection. |
| The Spectrum of Cutaneous Granulomatous Inflammation and Detection of Rubella Virus in Skin Biopsies of Patients With Common Variable Immune Deficiency
King AL , Johnson EF , Alavi A , Agrawal S , Sokumbi O , Perelygina L , Yorke L , Beard S , Wieland CN . J Cutan Pathol 2024 BACKGROUND: There is a known association between common variable immunodeficiency (CVID) and granulomas in multiple organ systems, including the skin, lung, liver, and spleen. Rubella virus has also been detected within cutaneous granulomas in both immunocompetent and immunocompromised hosts. We present a retrospective case series of patients with CVID and granulomatous skin disease and describe the spectrum of clinical and histopathologic features, including the status of rubella virus in the cutaneous granulomas. METHODS: We retrospectively reviewed the clinical and histopathological characteristics of patients diagnosed with CVID at our institution, with cutaneous findings and skin biopsies available for review between 1990 and 2023, demonstrating granulomatous inflammation. RESULTS: Eight patients met the inclusion criteria. The most common histopathologic pattern was palisaded granulomatous inflammation, seen in five of eight cases. Three cases showed strictly sarcoidal granulomas. Background inflammation was peri-granulomatous (8/8) and the predominant background inflammatory cell type was lymphocytic (6/8). Rubella virus testing was performed for seven of eight cases and found to be positive in one case. CONCLUSION: Cutaneous granulomatous disease in CVID can present with a spectrum of clinical morphologies, granulomatous patterns, and variable rubella virus persistence. Dermatopathologists should be aware of the spectrum of findings when considering cutaneous CVID-related granulomatous disease in the differential diagnosis. |
| Influenza, COVID-19, and respiratory syncytial virus vaccination coverage among adults - United States, Fall 2024
Kriss JL , Black CL , Razzaghi H , Meghani M , Tippins A , Santibanez TA , Stokley S , Chatham-Stephens K , Dowling NF , Peacock G , Singleton JA . MMWR Morb Mortal Wkly Rep 2024 73 (46) 1044-1051 The Advisory Committee on Immunization Practices (ACIP) recommends annual influenza and COVID-19 vaccination for all persons aged ≥6 months, including adults aged ≥18 years. ACIP also recommends a single lifetime dose of respiratory syncytial virus (RSV) vaccine for adults aged ≥75 years and for those aged 60-74 years who are at increased risk for severe RSV disease. Data from the National Immunization Survey-Adult COVID Module, a random-digit-dialed cellular telephone survey of U.S. adults aged ≥18 years, are used to monitor influenza, COVID-19, and RSV vaccination coverage. By the week ending November 9, 2024, an estimated 34.7% of adults aged ≥18 years reported having received an influenza vaccine, and 17.9% reported having received a COVID-19 vaccine for the 2024-25 respiratory virus season; 39.7% of adults aged ≥75 years, and 31.6% of adults aged 60-74 years at increased risk for severe RSV, had ever received an RSV vaccine. Coverage varied by jurisdiction and demographic characteristics and was lowest among younger adults and those without health insurance. Although early season estimates indicate that many adults are unprotected from respiratory virus infections, many appeared open to vaccination: overall, approximately 35% and 41% of adults aged ≥18 years reported that they definitely or probably will receive or were unsure about receiving influenza and COVID-19 vaccines, respectively, and 40% of adults aged ≥75 years reported that they definitely or probably will receive or were unsure about receiving RSV vaccine. Health care providers and immunization programs still have time to expand outreach activities and promote vaccination to increase coverage in preparation for the height of the respiratory virus season. Using these data can help health care providers and immunization programs identify undervaccinated populations and understand vaccination patterns to guide planning, implementation, and evaluation of vaccination activities. |
| Using double negative controls to adjust for healthy user bias in a recombinant Zoster Vaccine Safety Study
Li K , Emerman I , Cook AJ , Fireman BH , Sundaram M , Tseng HX , Weintraub ES , Yu O , Nelson JL , Shi X . Am J Epidemiol 2024 Unmeasured confounding is a major concern in many epidemiologic studies that are not randomized. Negative control methods can detect and reduce confounding by leveraging the proxies of the unmeasured confounders, including negative control outcomes (NCO) and exposures (NCE). An NCO is presumably unaffected by the exposure of interest but would be associated with unmeasured confounders; an NCE presumably does not affect the outcome of interest but would be associated with unmeasured confounders. A recently proposed double negative control method leverages both NCO and NCE for unmeasured confounding bias. To demonstrate this relatively new methodology in pharmacoepidemiologic studies, we re-analyzed data from a prior safety study of Recombinant Zoster Vaccine (RZV). The prior study compared risk of safety outcomes of RZV versus unvaccinated comparators, using logistic regression with propensity score adjustment. We identified NCOs and NCEs that could be used to adjust for unmeasured confounding bias that could arise if RZV recipients are incomparable to the comparators due to unmeasured factors. The double negative control analysis yielded relative risk estimates slightly closer to 1.0 than those reported previously, providing additional evidence of RZV safety that is less vulnerable to unmeasured confounding. |

MMWR Morb Mortal Wkly Rep 2024 73 (46) 1052-1057 Nursing home residents are at elevated risk for severe complications from respiratory viruses, including SARS-CoV-2, influenza, and respiratory syncytial virus (RSV). Nursing homes are required to report COVID-19 vaccination coverage and can voluntarily report influenza and RSV vaccination coverage among residents to CDC's National Healthcare Safety Network. The purpose of this study was to assess COVID-19, influenza, and RSV vaccination coverage among nursing home residents early in the 2024-25 respiratory virus season. As of November 10, 2024, 29.7% of nursing home residents had received a 2024-2025 COVID-19 vaccine. Among residents at facilities that elected to report vaccination against influenza (59.4% of facilities) and RSV (51.8% of facilities), 58.4% had received influenza vaccination, and 17.9% had received RSV vaccination. Vaccination coverage varied by U.S. Department of Health and Human Services region, social vulnerability index level, and facility size. Addressing low coverage with COVID-19, influenza, and RSV vaccines is a priority to protect residents who are susceptible to severe outcomes associated with respiratory illnesses. |
| Impact of the US maternal tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccination program on preventing pertussis in infants 2 to <6 months of age: A case-control evaluation
Skoff TH , Rubis AB , Kirley PD , Scherzinger K , McMahon M , McGuire S , Kudish K , Cieslak PR , Shang N , Hariri S . Open Forum Infect Dis 2024 11 (11) ofae655 BACKGROUND: To protect infants aged <2 months against pertussis, the United States recommends Tdap (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis) vaccination during each pregnancy. Data are limited on the strategy's effectiveness against pertussis in infants aged ≥2 months. METHODS: Pertussis case infants aged 2 to <6 months with cough onset between 1 January 2011 and 31 December 2014 were identified in 6 US states. Controls were 2 to <6 months of age, hospital matched, and selected by birth certificate. Mothers were interviewed to collect demographic and healthcare information. Provider-verified vaccination history was obtained for infants and mothers. Adjusted odds ratios (aORs) were calculated using conditional logistic regression; overall vaccine effectiveness (VE) was estimated as (1 - aOR)×100. To describe maternal Tdap VE modified by infant DTaP (diphtheria and tetanus toxoids and acellular pertussis) doses, case-control sets were unmatched, and a time-to-event analysis was conducted through a generalized linear mixed model. RESULTS: A total of 335 cases and 927 controls were enrolled. The overall adjusted VE estimate for Tdap during pregnancy was 45.6% (95% confidence interval [CI], 5.8%-68.5%) and increased slightly, but not significantly, against infant hospitalization (55.7% [-116.8% to 90.9%]). Although point estimates were not significant, VE was modified by infant DTaP doses (58.8% [95% CI, -6.0% to 84.0%] for 0 DTaP doses, 30.5% [-21.4% to 60.2%] for 1 dose, and 3.2% [-170.8% to 65.4%] for 2 doses). CONCLUSIONS: Our study suggests that there is some benefit of maternal Tdap vaccination beyond the first 2 months of life, however, on-time vaccination of infants remains critical to maintain protection from pertussis. |
| Herpes zoster vaccination among Medicare beneficiaries with and without prescription drug coverage
Tsai Y , Leung J , Anderson TC , Zhou F , Singleton JA . Vaccine 2024 43 126537 INTRODUCTION: The Inflation Reduction Act (IRA) eliminated cost sharing for Medicare Part D-covered vaccines but did not address the cost burden faced by Medicare beneficiaries who did not have prescription drug coverage. This study aimed to determine the characteristics of beneficiaries without prescription drug coverage and to assess the association between the receipt of a herpes zoster vaccine and prescription drug coverage status. METHODS: We used the 2019-2023 National Health Interview Survey and included Medicare beneficiaries aged 65 years and older who enrolled in both Parts A and B or a Medicare Advantage plan. Descriptive statistics were used to examine beneficiaries' characteristics. Logistic regressions were used to examine the associations between the receipt of a herpes zoster vaccine and Medicare prescription drug coverage. RESULTS: The study included 33,578 beneficiaries and 93.5 % of beneficiaries had prescription drug coverage. The prevalence of lacking prescription drug coverage was higher among beneficiaries who did not have a college degree, had family income below the poverty level, had no flu shot and well visit within the past year, and had no usual place for care. The probability of receiving a herpes zoster vaccine was higher among beneficiaries with prescription drug coverage than those without prescription coverage (45.2 % versus 25.3 %). CONCLUSIONS: Herpes zoster vaccination disparities between beneficiaries with and without prescription drug coverage existed before the IRA. Because the IRA only addresses the cost barrier facing by beneficiaries with prescription drug coverage, vaccination disparities was greater after the IRA implementation. |
| Measles-rubella microarray patches phase III clinical trial framework: Proposal and considerations

Vaccines (Basel) 2024 12 (11) Background: The Measles-Rubella Microarray Patch (MR-MAP) is an important technology that is expected to reduce coverage and equity gaps for measles-containing vaccines (MCVs), reach zero-dose children, and contribute to elimination of measles and rubella. MR-MAPs are anticipated to be easier to deploy programmatically and could be delivered by lesser-trained health workers, thereby increasing immunization coverage. The most advanced MR-MAP has reached clinical proof-of-concept through a Phase I/II trial in the target population of infants and young children. The World Health Organization (WHO) and partners have developed the Phase III clinical trial framework for MR-MAPs presented in this article. Objectives and Methods: The purpose of such framework is to inform the considerations, design and approach for the pivotal clinical trial design, while considering the anticipated data requirements to inform regulatory approval, WHO prequalification, and policy decision. Results: The proposed Phase III trial would compare the immunogenicity and safety of an MR-MAP with MR vaccine delivered subcutaneously in 9- to 10-month-old infants. An analysis of non-inferiority (NI) of immunogenicity would occur six weeks after the first dose. Should regulatory agencies or policy makers require, a proportion of infants could receive a second dose of either the same or alternate MR vaccine presentation six months after the first dose, with those children returning six weeks after the second dose for a descriptive assessment of immunogenicity, and then followed up six months after the second dose for evaluation of safety and immunogenicity. It is anticipated that this proposed pivotal Phase III trial framework would generate the required clinical data for regulatory licensure and WHO prequalification (PQ) of MR-MAPs. However, the trial design would need to be reviewed and confirmed by a national regulatory authority (NRA) that will assess the product for regulatory licensure and the WHO PQ team. Additional research will likely be required to generate data on concomitant vaccine delivery, the safety and immunogenicity of MR-MAPs in other age groups such as children 1-5 years and infants younger than 9 months of age, and the impact of MR-MAPs on coverage and equity. Such studies could be conducted during or after clinical MR-MAP development. |

Kanu JS , Vandi MA , Bangura B , Draper K , Gorina Y , Foster MA , Harding JD , Ikoona EN , Jambai A , Kamara MAM , Kaitibi D , Moffett DB , Singh T , Redd JT . Public Health Rev 2024 45 1607540 OBJECTIVES: World Health Organization issued Joint Statement on Data Protection and Privacy in the COVID-19 Response stating that collection of vast amounts of personal data may potentially lead to the infringement of fundamental human rights and freedoms. The Organization for Economic Cooperation and Development called on national governments to adhere to the international principles for data security and confidentiality. This paper describes the methods used to assist the Ministry of Health in bringing awareness of the data ownership, confidentiality and security principles to COVID-19 responders. METHODS: The Sierra Leone Epidemiological Data (SLED) Team data managers conducted training for groups of COVID-19 responders. Training included presentations on data confidentiality, information disclosure, physical and electronic data security, and cyber-security; and interactive discussion of real-life scenarios. A game of Jeopardy was created to test the participant's knowledge. RESULTS: This paper describes the methods used by the SLED Team to bring awareness of the DOCS principles to more than 2,500 COVID-19 responders. CONCLUSION: Similar efforts may benefit other countries where the knowledge, resources, and governing rules for protection of personal data are limited. |
| Real-world data versus probability surveys for estimating health conditions at the state level
Marker DA , Hilton C , Zelko J , Duke J , Rolka D , Kaufmann R , Boyd R . J Surv Stat Methodol 2024 12 (5) 1515-1530 Government statistical offices worldwide are under pressure to produce statistics rapidly and for more detailed geographies, to compete with unofficial estimates available from web-based big data sources or from private companies. Commonly suggested sources of improved health information are electronic health records and medical claims data. These data sources are collectively known as real-world data (RWD) because they are generated from routine health care processes, and they are available for millions of patients. It is clear that RWD can provide estimates that are more timely and less expensive to produce—but a key question is whether or not they are very accurate. To test this, we took advantage of a unique health data source that includes a full range of sociodemographic variables and compared estimates using all of those potential weighting variables versus estimates derived when only age and sex are available for weighting (as is common with most RWD sources). We show that not accounting for other variables can produce misleading and quite inaccurate health estimates. © 2024 American Association for Public Opinion Research. All rights reserved. |
| Concordance of traumatic brain injury symptoms, evaluation, and diagnosis between teens and parents: Data from the National Health Interview Survey-Teen
Black LI , Ng AE , Zablotsky B , Peterson A , Daugherty J , Waltzman D , Bose J . J Adolesc Health 2024 PURPOSE: To investigate differences in teen-reported and parent-reported lifetime prevalence estimates of traumatic brain injury (TBI) symptoms, TBI evaluation, and TBI diagnosis among a nationally representative sample of teenagers aged 12-17 years old and their parents. METHODS: Parent-reported data from the 2021 to 2022 National Health Interview Survey linked with teen-reported data from the National Health Interview Survey-Teen July 2021-December 2022 (n = 1,153) were analyzed. Lifetime prevalence estimates for TBI symptoms (e.g., selected symptoms as a result of a blow or jolt to the head), history of evaluation by health professional for TBI (i.e., TBI evaluation), and TBI diagnosis stratified by sociodemographic characteristics and reporter type were produced, and z-tests were conducted to test for differences. Concordance measures were calculated to assess agreement between teen and parent survey responses to TBI measures. RESULTS: Lifetime prevalence of TBI symptoms varied by reporter type across all sociodemographic characteristics with teen-report consistently producing higher estimates. Estimates of TBI evaluation varied by reporter type only among older teens, non-Hispanic teens, and teens who participated in sports; there was no difference for TBI diagnosis. Percent agreement between the 2 reporters ranged from 73% to 95%, prevalence-adjusted bias-adjusted kappa ranged from 0.45 to 0.90, and Cohen's kappa ranged from 0.22 to 0.63. DISCUSSION: There was general agreement for observable outcomes TBI evaluation and TBI diagnosis, but discordance existed in reports of TBI symptoms. These findings suggest that youth self-report of TBI symptoms may enhance surveillance efforts. |

| Detection of increased activity of human parvovirus B19 using commercial laboratory testing of clinical samples and source plasma donor pools - United States, 2024
Alfego D , Hernandez-Romieu AC , Briggs-Hagen M , Dietz S , Gillim L , Dale SE , Grover A , Albrecht J , Sesok-Pizzini D , Eisenberg M , Gregory CO , Poirier B . MMWR Morb Mortal Wkly Rep 2024 73 (47) 1076-1081
In most persons, human parvovirus B19 (B19) causes a mild respiratory illness, but infection can result in adverse health outcomes in persons who are pregnant, immunocompromised, or who have chronic hemolytic blood disorders. During the first quarter of 2024, several European countries reported increases in B19 activity. In the United States, there is no routine surveillance for B19. To assess increases in B19 activity in the United States, trends in testing and results from two independent populations were examined: 1) the presence of immunoglobulin (Ig) M antibodies, a marker of recent infection, in clinical specimens ordered by physicians and 2) B19 nucleic acid amplification testing (NAAT) in pooled donor source plasma from a large commercial laboratory during 2018-2024. The proportion of IgM-positive clinical specimens reached 9.9% in the second quarter (Q2) of 2024 after remaining <1.5% during 2020-2023 and was higher than Q2 peaks in 2018 (3.8%, p<0.001) and 2019 (5.1%, p<0.001). The prevalence of B19-NAAT-positive donor pools (512 donations per pool) reached 20% in June 2024 after remaining <2% during 2020-2023 and was higher than peaks in 2018 (6.7%, p<0.001) and 2019 (7.3%, p<0.001). Considering the B19 activity increase in the United States in 2024, promotion of measures to prevent respiratory viruses and monitor for adverse B19-related outcomes by health care providers and public health authorities might reduce adverse health outcomes in pregnant persons and others at increased risk. |
| Evaluating the effectiveness of external molecular proficiency testing in the Global Polio Laboratory Network, 2021-2022
Gerloff N , Burns CC . Pathogens 2024 13 (11)
In the Global Poliovirus Laboratory Network (GPLN), participation and successful completion in annual proficiency test (PT) panels has been a part of the WHO accreditation process for decades. The PT panel is a molecular external quality assessment (mEQA) that evaluates laboratory preparedness, technical proficiency, the accuracy of data interpretation, and result reporting. Using the Intratypic Differentiation (ITD) real-time RT-PCR kits from CDC, laboratories run screening assays and report results in accordance with the ITD algorithm to identify and type polioviruses. The mEQA panels consisted of 10 blinded, non-infectious lyophilized RNA transcripts, including programmatically relevant viruses and targets contained in the real-time PCR assays. Sample identities included wildtype, vaccine-derived (VDPV), Sabin-like polioviruses, enterovirus, and negatives, as well as categories of invalid and indeterminate. The performance of individual laboratories was assessed based on the laboratory's ability to correctly detect and characterize the serotype/genotype identities of each sample. The scoring scheme assessed the laboratory readiness following GPLN guidelines. Laboratories receiving mEQA scores of 90 or higher passed the assessment, scores of less than 90 failed and required remedial actions and re-evaluation. In 2021 and 2022, 123 and 129 GPLN laboratories were invited to request the annual PT panel, and 118 and 127 laboratories submitted results, respectively. The overall results were good, with 86% and 91.5% of laboratories passing the PT panel on their first attempt in 2021 and 2022, respectively. Most labs scored the highest score of 100, and less than one quarter scored between 90 and 95. Less than 10% of submitting laboratories failed the PT, resulting in in-depth troubleshooting to identify root causes and remediations. Most of these laboratories were issued a second PT panel for repeat testing, and almost all laboratories passed the repeat PT panel. The results of the 2021 and 2022 annual mEQA PTs showed that, despite the COVID-19 pandemic, the performance remained high in the GPLN, with most labs achieving the highest score. For these labs, the real-time PCR assay updates that were implemented during 2021-2022 were carried out with full adherence to procedures and algorithms. Even initially failing labs achieved passing scores after remediation. |

Reliable, validated diagnostic tests are critical for rabies control in animals and prevention in people. We present a performance assessment and updates to the LN34 real-time RT-PCR assay for rabies diagnosis in postmortem animal brain samples. In two U.S. laboratories during 2017 to 2022, routine used of the LN34 assay produced excellent diagnostic sensitivity (99.72% to 100%) and specificity (99.99% to 100%) compared to the direct fluorescence antibody test (DFA). Almost all (>90%) DFA indeterminate results caused by non-specific or atypical fluorescence were negative by LN34 testing, representing up to 111 cases where unnecessary post-exposure prophylaxis could be avoided. LN34 assay original primer sequences showed low sensitivity for some rare lyssaviruses. Increased primer concentration combined with new primer formulation showed improved performance for impacted lyssaviruses with no loss in performance across diverse rabies virus variants from clinical samples. The updated LN34 and internal control assays were combined into a single-well LN34 multiplexed (LN34M) format, run at half reagent volumes. The LN34M assay showed similar detection of rabies virus to the singleplexed assay with simplified assay set-up, lower cost, and improved quality controls. |
| Use of multiplex molecular panels to diagnose urinary tract infection in older adults
Hatfield KM , Kabbani S , See I , Currie DW , Kim C , Jacobs Slifka K , Magill SS , Hicks LA , McDonald LC , Jernigan J , Reddy SC , Lutgring JD . JAMA Netw Open 2024 7 (11) e2446842 IMPORTANCE: Multiplex molecular syndromic panels for diagnosis of urinary tract infection (UTI) lack clinical data supporting their use in routine clinical care. They also have the potential to exacerbate inappropriate antibiotic prescribing. OBJECTIVE: To describe the frequency of unspecified multiplex testing in administrative claims with a primary diagnosis of UTI in the Medicare population over time, to assess costs, and to characterize the health care professionals (eg, clinicians, laboratories, physician assistants, and nurse practitioners) and patient populations using these tests. DESIGN, SETTING, AND PARTICIPANTS: This cohort study used Centers for Medicare & Medicaid Services (CMS) claims data for Medicare beneficiaries. The study included older community-dwelling adults and nursing home residents with fee-for-service Medicare Part A and Part B benefits from January 1, 2016, to December 31, 2023. MAIN OUTCOMES AND MEASURES: Multiplex syndromic panels were identified using carrier claims (ie, claims for clinician office or laboratory services). The annual rate of claims was measured for multiplex syndromic panels with a primary diagnosis of UTI per 10 000 eligible Medicare beneficiaries. The performing and referring specialties of health care professionals listed on claims of interest and the proportion of claims that occurred among beneficiaries residing in a nursing home were described. RESULTS: Between 31 110 656 and 36 175 559 Medicare beneficiaries with fee-for-service coverage annually (2016-2023) were included in this study. In this period, 1 679 328 claims for UTI multiplex testing were identified. The median age of beneficiaries was 77 (IQR, 70-84) years; 34% of claims were from male beneficiaries and 66% were from female beneficiaries. From 2016 to 2023, the observed rate of UTI multiplex testing increased from 2.4 to 148.1 claims per 10 000 fee-for-service beneficiaries annually, and the proportion of claims that occurred among beneficiaries residing in a nursing home ranged from 1% in 2016 to 12% in 2020. In addition to laboratories or pathologists, urology was the most common clinician specialty conducting this testing. The CMS-assigned referring clinician specialty was most frequently urology or advanced practice clinician for claims among community-dwelling beneficiaries compared with internal medicine or family medicine for claims among nursing home residents. In 2023, the median cost of a multiplex test in the US was $585 (IQR, $516-$695 for Q1-Q3), which was more than 70 times higher than the median cost of $8 for a urine culture (IQR, $8-$16 for Q1-Q3). CONCLUSIONS AND RELEVANCE: This cohort study of Medicare beneficiaries with fee-for-service coverage from 2016 to 2023 found increasing use of emerging multiplex testing for UTI coupled with high costs to the Medicare program. Monitoring and research are needed to determine the effects of multiplex testing on antimicrobial use and whether there are clinical situations in which this testing may benefit patients. |
| Human biomonitoring health-based guidance values: A case study of the HB2GV Dashboard and DEHP
Macey K , Lange R , Apel P , Poddalgoda D , Calafat AM , Kolossa-Gehring M , LaKind JS , Melnyk LJ , Nakayama SF , St-Amand A , Pollock T . Int J Hyg Environ Health 2024 263 114490 In 2022, the International Society of Exposure Science (ISES) International Human Biomonitoring (i-HBM) Working Group launched a free, online repository of biomonitoring guidance values referred to as the Human Biomonitoring Health-Based Guidance Value (HB2GV) Dashboard. The goal of the Dashboard is to assist global human biomonitoring data users (e.g., risk assessors, risk managers) and human biomonitoring programs with a readily available compilation of guidance values for the general population. The Dashboard contains approximately 600 HB2GVs for over 150 chemicals or their metabolites. Although there are many different types of HB2GVs, most are Biomonitoring Equivalents (BEs), Human Biomonitoring (HBM-I and HBM-II) values, or Human Biomonitoring Guidance Values (HBM-GVs). For users new to human biomonitoring, understanding how the different types of HB2GVs are derived and how to interpret those values in the context of human biomonitoring data can be difficult. Therefore, there is a need to inform users of the differences among available guidance values and to help users identify the HB2GV that could be most suitable for their purposes. Here, we summarize the derivation of HB2GVs for a case study chemical, di-(2-ethylhexyl) phthalate (DEHP). We selected DEHP as there are 36 unique HB2GVs available from three of the most common types of guidance values (i.e., BE, HBM-I value, HBM-GV). We also compare the available HB2GVs with a focus on the differences among their derivation methods, relative quality and confidence, and interpretation. This case study provides guidance on the use of existing HB2GVs for health-based interpretation of human biomonitoring data that may be applied to other chemicals. As with any other type of guidance or regulatory value (e.g., RfDs, MRLs), thoughtful selection and use are strongly encouraged. Appropriately interpreting HBM data with the aid of guidance values can result in improved decision making which, ultimately, could lead to better protection of public health. |
| CDC's Core Elements to promote diagnostic excellence
Morgan DJ , Singh H , Srinivasan A , Bradford A , McDonald LC , Kutty PK . Diagnosis (Berl) 2024 Nearly a decade after the National Academy of Medicine released the "Improving Diagnosis in Health Care" report, diagnostic errors remain common, often leading to physical, psychological, emotional, and financial harm. Despite a robust body of research on potential solutions and next steps, the translation of these efforts to patient care has been limited. Improvement initiatives are still narrowly focused on selective themes such as diagnostic stewardship, preventing overdiagnosis, and enhancing clinical reasoning without comprehensively addressing vulnerable systems and processes surrounding diagnosis. To close this implementation gap, the US Centers for Disease Control and Prevention (CDC) released the Core Elements of Hospital Diagnostic Excellence programs on September 17, 2024. This initiative aligns with the World Health Organization's (WHO) 2024 World Patient Safety Day focus on improving diagnosis. These Core Elements provide guidance for the formation of hospital programs to improve diagnosis and aim to integrate various disparate efforts in hospitals. By creating a shared mental model of diagnostic excellence, the Core Elements of Diagnostic Excellence supports actions to break down silos, guide hospitals toward multidisciplinary diagnostic excellence teams, and provide a foundation for building diagnostic excellence programs in hospitals. |
| Impact of vitamin D on hyperoxic acute lung injury in neonatal mice
Tran TT , Davies J , Johnston RA , Karmouty-Quintana H , Li H , Crocker CE , Khan AM , Alcorn JL . BMC Pulm Med 2024 24 (1) 584 BACKGROUND: Prolonged exposure to hyperoxia can lead to hyperoxic acute lung injury (HALI) in preterm neonates. Vitamin D (VitD) stimulates lung maturation and acts as an anti-inflammatory agent. Our objective was to determine if VitD provides a dose-dependent protective effect against HALI by reducing inflammatory cytokine expression and improving alveolarization and lung function in neonatal mice. METHODS: C57BL/6 mouse neonates were randomized and placed in room air or hyperoxic (85% O(2)) conditions for 6 days. Control, low (5 ng/neonate) and high (25 ng/neonate) doses of VitD were administered daily beginning at day 2 via oral gavage. Lung tissue was analyzed for edema, changes in pulmonary structure and function, and inflammatory cytokine expression. RESULTS: Neonatal mice treated with VitD in hyperoxic conditions had improved weight gain, reduced pulmonary edema and increased alveolar surface area compared to untreated pups in hyperoxia. No significant changes in cytokine expression were observed between untreated and VitD neonates. While changes in surfactant protein mRNA expression were impacted by hyperoxia and VitD administration, no significant changes in alveolar type II cell percentages were observed. At 3 weeks, mice in hyperoxia treated with VitD had greater lung compliance, diminished airway reactivity and improved weight gain. CONCLUSIONS: High dose VitD significantly limited harmful effects of HALI. These results suggest that supplementation of VitD to neonatal mice during hyperoxia exposure provides both short-term and long-term protective benefits against HALI. |
| Updated findings on temporal variation in radiation-effects on cancer mortality in an international cohort of nuclear workers (INWORKS)
Daniels RD , Bertke SJ , Kelly-Reif K , Richardson DB , Haylock R , Laurier D , Leuraud K , Moissonnier M , Thierry-Chef I , Kesminiene A , Schubauer-Berigan MK . Eur J Epidemiol 2024
The International Nuclear Workers Study (INWORKS) contributes knowledge on the dose-response association between predominantly low dose, low dose rate occupational exposures to penetrating forms of ionizing radiation and cause-specific mortality. By extending follow-up of 309,932 radiation workers from France (1968-2014), the United Kingdom (1955-2012), and the United States (1944-2016) we increased support for analyses of temporal variation in radiation-cancer mortality associations. Here, we examine whether age at exposure, time since exposure, or attained age separately modify associations between radiation and mortality from all solid cancers, solid cancers excluding lung cancer, lung cancer, and lymphohematopoietic cancers. Multivariable Poisson regression was used to fit general relative rate models that describe modification of the linear excess relative rate per unit organ absorbed dose. Given indication of greater risk per unit dose for solid cancer mortality among workers hired in more recent calendar years, sensitivity analyses considering the impact of year of hire on results were performed. Findings were reasonably compatible with those from previous pooled and country-specific analyses within INWORKS showing temporal patterns of effect measure modification that varied among cancers, with evidence of persistent radiation-associated excess cancer risk decades after exposure, although statistically significant temporal modification of the radiation effect was not observed. Analyses stratified by hire period (< 1958, 1958+) showed temporal patterns that varied; however, these analyses did not suggest that this was due to differences in distribution of these effect measure modifiers by hire year. |
| Evaluating injury and illness trends in federal and Postal Service employees using workers' compensation claims data 2007-2022
Wurzelbacher SJ , Krieg EF , Meyers AR , Bushnell PT , Van Nguyen N , Tseng CY . J Occup Environ Med 2025 [Epub ahead of print] Objective: The purpose of this study was to understand federal workplace injury/illness trends. Methods: Over 1.5 million federal and Postal Service employee workers' compensation (WC) claims from 2007 to 2022 were linked to employment data and analyzed. Results: From 2007 to 2019, Falls, Slips, Trips represented the highest proportion of claims (30.7%), followed by Overexertion and Bodily Reaction (24.4%), Unclassified (16.4%), Contact with Objects and Equipment (13.1%), Violence and Other Injuries by Persons or Animals (8.8%), Transportation Incidents (4.0%), Exposure to Harmful Substances or Environments (2.5%), and Fires and Explosions (0.24%). From 2020 to 2022, COVID-19 drove a major shift to Exposure to Harmful Substances or Environments representing the highest proportion of claims (44.3%). Conclusions: Claims data represent a potentially rich data source that employing agencies can use to focus prevention and treatment of injury/illness. |
| Mentor–protégé matching regarding communication relates to career attitudes
O’Brien KE , Mann KJ , Woody BA . J Career Dev 2024 In this study, we investigate the role of matching communication (i.e., relational messages received) in mentoring outcomes (mentor and protégé career attitudes). Specifically, we used data from a sample of 145 matched mentor–protégé dyads in a response surface analysis to show that matched relational messaging generally relates to mentors (and less consistently, protégés) reporting enhanced career satisfaction and career commitment. Furthermore, our findings are consistent with previous research showing that when relational messages (i.e., intimacy) or self-disclosure are matched at high or low (i.e., more extreme) levels, the mentor and protégé have the best outcomes. Additionally, beneficial mentor outcomes were maximized when levels of seriousness were matched at a moderate level. These results suggest that both levels of relational messaging, as well as the degree to which mentors and protégé match on these constructs influences mentoring outcomes. Study limitations, future directions for research, and implications for career development are discussed. © The Author(s) 2024. |
| Population-based cohort data used to assess trends in early resumption of sexual activity after voluntary medical male circumcision in Rakai, Uganda
Daama A , Nalugoda F , Kankaka E , Kasango A , Nantume B , Kigozi GN , Ssekubugu R , Namutundu J , Ssettuba A , Lutalo T , Kagaayi J , Nakigozi G , Alamo S , Mills LA , Kabuye G , Gray R , Wawer M , Serwadda D , Sewankambo N , Kigozi G . PLoS One 2024 19 (11) e0297240 INTRODUCTION: Voluntary medical male circumcision (VMMC) reduces the risk of heterosexual acquisition of HIV by 50%-60%. The Uganda Ministry of Health recommends abstinence of sex for 42 days after VMMC to allow complete wound healing. However, some men resume sex early before the recommended period. We estimated trends in prevalence and risk factors of early sex resumption (ESR) among VMMC clients in Rakai, Uganda, from 2013-2020. METHODS: Data from the Rakai Community Cohort Study (RCCS), a cross-sectional study, were analyzed. Data included consenting males aged 15-49 years in RCCS who self-reported having received VMMC between the period of 2013 to 2020. ESR prevalence and associated risk factors were assessed using modified Poisson regression to estimate adjusted prevalence ratios (aPR). RESULTS: Overall, 1,832 participants were included in this study. ESR decreased from 45.1% in 2013 to 14.9% in 2020 (p<0.001). Across the first three surveys, ESR prevalence was consistently higher among the married participants than the never married participants, aPR = 1.83, 95% CI: [1.30,2.57]; aPR = 2.46, 95% CI: [1.50,4.06]; aPR = 2.22, 95% CI: [1.22,4.03]. ESR prevalence was higher among participants who reported to have more than one sexual partner than participants with one partner, aPR = 1.59, 95% CI: [1.16,2.20]. In the fourth survey from 2018-2020, ESR prevalence was significantly higher among participants with primary education than participants with post-primary, aPR = 2.38, 95% CI: [1.31, 4.30]. However, ESR prevalence was lower among participants aged at least 45 years than participants aged 15-19 years, aPR = 0.0, 95% CI: [1.86e-07, 2.69e-06]. Overall, participants who reported primary school as their highest level of education reported ESR more often than those with post-primary education aPR = 2.38, 95% CI: [1.31, 4.30]. Occupation and known HIV status were not associated with ESR. CONCLUSIONS: Self-reported ESR after VMMC declined between 2013 and 2020. Targeted efforts for counseling focusing on married men, men who had multiple sex partners, and men with lower levels of education may decrease ESR. |
| Abortion surveillance - United States, 2022
Ramer S , Nguyen AT , Hollier LM , Rodenhizer J , Warner L , Whiteman MK . MMWR Surveill Summ 2024 73 (7) 1-28 PROBLEM/CONDITION: CDC conducts abortion surveillance to document the number and characteristics of women obtaining legal induced abortions and the number of abortion-related deaths in the United States. PERIOD COVERED: 2022. DESCRIPTION OF SYSTEM: Each year, CDC requests abortion data from the central health agencies for the 50 states, the District of Columbia, and New York City. For 2022, a total of 48 reporting areas voluntarily provided aggregate abortion data to CDC. Of these, 47 reporting areas provided data each year during 2013-2022. Census and natality data were used to calculate abortion rates (number of abortions per 1,000 women aged 15-44 years) and ratios (number of abortions per 1,000 live births), respectively. Abortion-related deaths from 2021 were assessed as part of CDC's Pregnancy Mortality Surveillance System (PMSS). RESULTS: For 2022, a total of 613,383 abortions were reported to CDC from 48 reporting areas. Among 47 reporting areas with data each year during 2013-2022, in 2022, a total of 609,360 abortions were reported, the abortion rate was 11.2 abortions per 1,000 women aged 15-44 years, and the abortion ratio was 199 abortions per 1,000 live births. From 2021 to 2022, the total number of abortions decreased 2% (from 622,108 total abortions), the abortion rate decreased 3% (from 11.6 abortions per 1,000 women aged 15-44 years), and the abortion ratio decreased 2% (from 204 abortions per 1,000 live births). From 2013 to 2022, the total number of reported abortions decreased 5% (from 640,154), the abortion rate decreased 10% (from 12.4 abortions per 1,000 women aged 15-44 years), and the abortion ratio increased 1% (from 198 abortions per 1,000 live births).In 2022, women in their 20s accounted for more than half of abortions (56.5%). Women aged 20-24 and 25-29 years accounted for the highest percentages of abortions (28.3% and 28.2%, respectively) and had the highest abortion rates (18.1 and 18.7 abortions per 1,000 women aged 20-24 and 25-29 years, respectively). By contrast, adolescents aged <15 years and women aged ≥40 years accounted for the lowest percentages of abortions (0.2% and 3.6%, respectively) and had the lowest abortion rates (0.4 and 2.5 abortions per 1,000 women aged <15 and ≥40 years, respectively). However, abortion ratios were highest among adolescents (aged ≤19 years) and lowest among women aged 30-39 years.From 2021 to 2022, abortion rates decreased among women aged ≥20 years and did not change among adolescents (aged ≤19 years). Abortion rates decreased from 2013 to 2022 among all age groups, except women aged 30-34 years for whom it increased. The decrease in the abortion rate from 2013 to 2022 was highest among adolescents compared with other age groups. From 2021 to 2022, abortion ratios increased for adolescents and decreased among women aged ≥20 years. From 2013 to 2022, abortion ratios increased among adolescents and women aged 20-34 years and decreased among women aged ≥35 years.In 2022, the majority (78.6%) of abortions were performed at ≤9 weeks' gestation, and nearly all (92.8%) were performed at ≤13 weeks' gestation. During 2013-2022, the percentage of abortions performed at >13 weeks' gestation remained low (≤8.7%). In 2022, the highest percentage of abortions were performed by early medication abortion at ≤9 weeks' gestation (53.3%), followed by surgical abortion at ≤13 weeks' gestation (35.5%), surgical abortion at >13 weeks' gestation (6.9%), and medication abortion at >9 weeks' gestation (4.3%); all other methods were uncommon (<0.1%). Among those that were eligible (≤9 weeks' gestation), 70.2% of abortions were early medication abortions. In 2021, the most recent year for which PMSS data were reviewed for pregnancy-related deaths, five women died as a result of complications from legal induced abortions. INTERPRETATION: Among the 47 areas that reported data continuously during 2013-2022, overall decreases were observed over this time in the number and rate of reported abortions and an increase was observed in the abortion ratio; in addition, from 2021 to 2022, decreases of 2%-3% were observed across all measures. PUBLIC HEALTH ACTION: Abortion surveillance can be used to help evaluate programs aimed at promoting equitable access to patient-centered quality contraceptive services in the United States to reduce unintended pregnancies. |
| Special Report from the CDC: Driving under the influence of alcohol, marijuana, or other illicit drugs among drivers aged ≥16 years — National Survey on Drug Use and Health, 2016–2019
Schumacher AC , De Crescenzo LA , Yellman MA , Sauber-Schatz EK . J Saf Res 2024 Introduction: This study describes the prevalence of driving under the influence of alcohol (DUIA), marijuana (DUIM), or other illicit drugs (DUID) in the United States over time. Method: This study analyzed data from 2016–2019 National Survey on Drug Use and Health public-use files. The study sample was limited to drivers aged ≥16 years. Prevalence in 2019 and 2016–2019 trends were assessed overall, by sociodemographic characteristics, and by seatbelt use. Results: The 2019 overall prevalence of DUIA, DUIM, and DUID during the past year was 8.3%, 5.3%, and 0.9%, respectively. DUIA, DUIM, and DUID prevalence was highest for drivers who were male (10.6%, 7.0%, and 1.2%, respectively), not heterosexual (12.3%, 14.7%, and 3.5%, respectively), and did not always wear a seatbelt (12.1%, 11.5%, and 3.1%, respectively). DUIA and DUIM were highest among drivers aged 21–25 years; DUID was highest among drivers aged 21–25 or 26–34 years. From 2016 to 2019, overall DUIA decreased slightly, DUIM increased (4.5% to 5.3%), and DUID did not change; trends differed across sociodemographic groups. Conclusions: DUI is a pervasive public health issue. There are ≥10,000 DUIA crash deaths in the United States annually; proven interventions exist to prevent these deaths. Decision makers can save lives and make our roadways safer by implementing proven strategies to reduce DUIA, including lowering the legal blood alcohol concentration (BAC) for driving. Improved data and more research are needed to understand DUIM and DUID burden and determine effective prevention strategies, especially in the context of increasing DUIM. Practical Applications: There were groups for which changes in behavior patterns were found, which could guide prevention efforts. For drivers who did not always wear a seatbelt, DUIA decreased while DUIM increased. A similar pattern was noted for drivers aged 26–34 years; additionally, DUID increased in this group. © 2024 |
| FIRST REPORT OF Dicrocoelium SP. IN HOARY FOX (Lycalopex vetulus Lund 1842) (CARNIVORA: CANIDAE) FECES
Barçante TA , Muniz de Paiva Barçante J , Seixas JN , de Freitas Milagres T , Peixoto JV , Traversa D , dos Santos Lima W . J Trop Patho 2024 53 (3) 223-229 The hoary fox (Pseudalopex vetulus), endemic to Brazil’s Cerrado region, is a wild canid species facing ecological pressures from urbanization and habitat fragmentation. These pressures increase the risk of pathogen transmission between wild and domestic animals, particularly in rural and peri-urban areas. This study reports the first report of Dicrocoelium sp. and Hepatozoon spp. infections in a wild female hoary fox in Southeast Brazil. The fox, presented with neurological disorders, dehydration, and poor nutritional condition, was hospitalized and subjected to a series of parasitological and clinical tests. Blood smears and fecal examinations revealed the presence of Hepatozoon sp. gametocytes and a significant number of Dicrocoelium eggs. The fox received treatment with albendazole, enrofloxacin, and N-acetylcysteine, showing progressive improvement before being reintroduced to its habitat. This study highlights the significance of parasitic infections in wild canids, emphasizing the need for further research on the ecological and health impacts of such infections. It also underscores the importance of comprehensive fecal and hematological examinations in the clinical assessment of wild fauna and raises awareness about the potential of wild canids as reservoirs for zoonotic parasites. © 2024 Brazilian Society of Parasitology.

J Am Vet Med Assoc 2024 1-5 OBJECTIVE: Pet ownership among people experiencing homelessness (PEH) is common, but access to shelter, veterinary care, and flea-preventative products for PEH who own pets in the US is not well described. We sought to evaluate current knowledge of fleas and flea-borne diseases and characterize practices around pets and service animals among staff at homeless shelters and outreach organizations. METHODS: In-person surveys were administered to staff at homeless shelters and on outreach teams in 7 states from August 2022 to April 2023 to evaluate knowledge, attitudes, and practices and to assess homeless shelter/organizational characteristics. RESULTS: Surveys were administered to 333 staff members at 60 homeless shelters and among 29 outreach teams. Seventy-eight percent of homeless shelters allowed pets or service animals. Only 2% of homeless shelters and 7% of outreach teams provided veterinary care; 15% of homeless shelters and 7% of outreach teams provided flea preventatives. Nearly three-quarters of surveyed homeless shelter staff responded that no steps were taken to treat fleas at their shelters. CONCLUSIONS: Veterinary care and availability of flea-preventative products are limited in homeless shelter and outreach organizations serving people experiencing homelessness. CLINICAL RELEVANCE: Pets of PEH might be at an increased risk of flea infestation and flea-borne diseases because of limited access to veterinary care and preventatives. Improving knowledge and access to flea prevention, screening, and treatment are critical to ensure PEH and their pets can consistently access homeless shelters or outreach services, and to prevent flea-borne disease transmission. |

Bartonella quintana infection can lead to bacillary angiomatosis, peliosis hepatis, chronic bacteremia, and culture-negative endocarditis. Transmitted by the human body louse (Pediculus humanus humanus), B. quintana infection has become an emerging disease in recent decades among persons experiencing homelessness. By using retrospective laboratory surveillance, we identified 5 cases of left-sided, culture-negative B. quintana endocarditis among persons in New York, New York, USA, during January 1, 2020-November 23, 2023. Identifications were made by using molecular assays. All patients experienced unsheltered homelessness in the year before hospitalization. Of those patients, 4 experienced heart failure, 3 renal failure, and 2 embolic strokes; 2 died. Aortic valve replacement occurred in 4 cases. A history of possible body louse infestation was found in 4 cases. Clinicians should consider housing status and history of lice exposure in patients with suspected bartonellosis and have a low threshold for diagnostic testing and empiric treatment in patients experiencing homelessness. |
| Severe and fatal Rocky Mountain spotted fever after exposure in Tecate, Mexico - California, July 2023-January 2024
Kjemtrup AM , Hacker JK , Monroe M , Williams V , Lines C , Lopez K , Paddock CD , Carpenter A , Salzer JS , Villalba JA , Bhatnagar J , Shah S , Iniguez-Stevens E , Efthemeou TC , Hernandez V , Vugia DJ , Kramer VL . MMWR Morb Mortal Wkly Rep 2024 73 (47) 1069-1075 Rocky Mountain spotted fever (RMSF) is a tickborne disease endemic in areas of the Americas. Persistent high incidence of the disease exists in northern Mexico, perpetuated by local populations of brown dog ticks (Rhipicephalus sanguineus sensu lato) and free-roaming dogs. Six cases of RMSF caused by Rickettsia rickettsii, including three deaths, were reported to the California Department of Public Health during July 2023-January 2024. All six patients were eventually determined to have had exposure to R. rickettsii in Tecate, Mexico, a municipality on the U.S. border that had not been previously described as a high-risk RMSF area. Identification and reporting of the cases were complicated by challenges in diagnosis. The serious nature of the disease and delays in initiating appropriate treatment can result in life-threatening consequences. Epidemiologic collaborations among local, state, federal, and international public health agencies were essential to identifying Tecate as the location of exposure. Further collaborations will be important for directing future prevention measures. Increased health care provider awareness of RMSF is critical on both sides of the border to facilitate earlier diagnosis and initiation of appropriate treatment. |
| Serosurvey of arboviruses in free-ranging mantled howler monkeys (Alouatta palliata) in Costa Rica
Larsen RS , Moresco A , Karabatsos N , Dolz G , Glander KE . J Wildl Dis 2024 We investigated the prevalence of arthropod-borne viral diseases in a population of free-ranging mantled howler monkeys (Alouatta palliata) in Costa Rica in 1998. Blood samples were opportunistically collected from monkeys anesthetized for another study. Serology was performed on 64 individuals to assess exposure of this population to vesicular stomatitis virus, equine encephalitis viruses, Mayaro virus, St. Louis encephalitis virus, yellow fever virus, and dengue virus. The New Jersey serotype of vesicular stomatitis (VSV-NJ) was the only pathogen for which the population tested positive (44% [28/64]). This is the first report of antibodies against VSV-NJ in nonhuman primates in Costa Rica. |

In a US survey of infectious disease specialists, 61 respondents reported seeing >1 Bartonella quintana infection during 2014-2024. Diagnostic challenges included limited healthcare provider awareness, inadequate testing, and inconsistent healthcare access among affected populations. Early recognition of B. quintana infections is needed to improve outcomes among affected populations. |
| Operational risk assessment tool for evaluating leishmania infantum introduction and establishment in the United States through dog importation(1)
Marquez DR , Straily A , Nachman K , Norris DE , Davis MF , Petersen CA . Emerg Infect Dis 2024 30 (12) 1-14 International pet travel and commercial operations have increased animal disease importation risks, including for Leishmania infantum, a deadly parasite of humans and domestic dogs. Collaborating as an interdisciplinary working group, we developed an operational tool for veterinary and public health practitioners to assess and manage L. infantum risk in dogs imported to the United States. Overall risk varies by dog, human, and geographic factors but could be high without proper controls. We determined dog risk management strategies should include application of sand fly insecticides and repellents, sterilization, and treatment. US public health authorities can use a One Health approach to manage L. infantum importation risks via infected dogs. |

Price ER , McDermott D , Sherman A , Kelley L , Mehr J , Greeley R , Cole SD . Emerg Infect Dis 2024 30 (12) 2689-2691
We report 2 canine cases of carbapenemase-producing Pseudomonas aeruginosa within a United States veterinary hospital associated with a human outbreak linked to over-the-counter artificial tears. We investigated veterinary hospital transmission. Veterinary antimicrobial resistance surveillance and infection prevention and control enhancements are needed to reduce transmission of carbapenemase-producing organisms. |
