Using adaptive behavior scores to convey level of functioning in children with autism spectrum disorder: Evidence from the Study to Explore Early Development
Furnier SM , Ellis Weismer S , Rubenstein E , Gangnon R , Rosenberg S , Nadler C , Wiggins LD , Durkin MS . Autism 2023 13623613231193194 Autistic people are often described as "low-" or "high-functioning" based on their scores on cognitive tests. These terms are common in publications and in everyday communication. However, recent research and feedback from the autistic community suggests that relying on cognitive ability alone to describe functioning may miss meaningful differences in the abilities of autistic children and adults and in the kinds of support they may need. Additional methods are needed to describe "functioning" in autistic children. We examined whether scores from a test measuring adaptive behaviors would provide information on the functional abilities of children with autism that is different from cognitive ability and autism symptom severity. Adaptive behaviors include age-appropriate skills that allow people to function in their everyday lives and social interactions. We found that a large amount of the variation in adaptive behavior scores was not explained by cognitive development, autism symptom severity, and behavioral and emotional problems. In addition, there was a wide range of adaptive ability levels in children with autism in our study, including in those with low, average, or high cognitive scores. Our results suggest that adaptive behavior scores could provide useful information about the strengths and support needs of autistic children above and beyond measures of cognitive ability and autism symptom severity. Adaptive behavior scores provide important information on the needs of autistic people. |
Prevalence of amyotrophic lateral sclerosis in the United States, 2018
Mehta P , Raymond J , Zhang Y , Punjani R , Han M , Larson T , Muravov O , Lyles RH , Horton DK . Amyotroph Lateral Scler Frontotemporal Degener 2023 1-7 OBJECTIVE: To estimate prevalent ALS cases in the United States for calendar year 2018. METHODS: The National ALS Registry (Registry) compiled data from national administrative databases (from the Centers for Medicare and Medicaid Services, the Veterans Health Administration, and the Veterans Benefits Administration) and enrollment data voluntarily submitted through a web portal (www.cdc.gov/als). We used log-linear capture-recapture (CRC) model-based methodology to estimate the number of cases not ascertained by the Registry. RESULTS: The Registry identified 21,655 cases of ALS in 2018, with an age-adjusted prevalence of 6.6 per 100,000 U.S. population. When CRC methods were used, an estimated 29,824 cases were identified, for an adjusted prevalence of 9.1 per 100,000 U.S. population. The demographics of cases of ALS did not change from previous year's reports. ALS continues to impact Whites, males, and persons over 50 years of age more so than other comparison groups. The results from the present report suggest case ascertainment for the Registry has improved, with the estimate of missing prevalent cases decreasing from 44% in 2017 to 27% in in 2018. DISCUSSION: Consistent with previous estimates that used CRC, ALS prevalence in the United States is about 29,824 cases per year. |

Influenza-associated respiratory illness among five cohorts of pregnant women and their young infants (0-6months), Bangladesh, 2013-2017
Akhtar Z , Ghosh P , Bhuiyan M , Sturm-Ramirez K , Rahman M , Howlader M , Dawood F , Chowdhury F , Iuliano D . Influenza Other Respir Viruses 2023 17 (8) e13175 BACKGROUND: Pregnant women with their infants are considered at higher risk for influenza-associated complications, and the World Health Organization (WHO) recommends influenza vaccination during pregnancy to protect them, including their infants (0-6 months). There are limited data on the influenza burden among pregnant women and their infants (0-6 months), and there are no routine influenza vaccinations in Bangladesh. METHODS: Five annual cohorts (2013-2017) of pregnant women were enrolled from the eight sub-districts of Bangladesh before the influenza season (May-September); they were contacted weekly to identify new onset of influenza-like illness (ILI) (subjective or measured fever and cough) and acute respiratory illness (ARI) (at least two of these symptoms: cough, rhinorrhea, or difficulty in breathing) among their infants from birth to 6 months of age. We collected nasopharyngeal swabs from ILI and ARI cases, tested by real-time reverse transcription polymerase chain reaction (rRT-PCR) for influenza virus (including types and subtypes) and estimated influenza incidence (95% CI)/10000 pregnant women-months or infant-months, respectively. RESULTS: We enrolled 9020 pregnant women, followed for 26,709 pregnancy-months, and detected 1241 ILI episodes. We also followed 8963 infants for 51,518 infant-months and identified 5116 ARI episodes. Influenza positivity was 23% for ILI and 3% for ARI cases. The overall incidence (2013-2017) of influenza among pregnant women was 158.5/10000 pregnant women-months (95% CI: 141.4-177.6) and that among infants was 21.9/10000 infant-months (95% CI: 18.2-26.5). CONCLUSIONS: Although the data was collected more than 5 years ago, as the only baseline data, our findings illustrate evidence of influenza burden among pregnant women and infants (0-6 months), which may support preventive policy decisions in Bangladesh. |
Global and regional estimates of genital human papillomavirus prevalence among men: a systematic review and meta-analysis
Bruni L , Albero G , Rowley J , Alemany L , Arbyn M , Giuliano AR , Markowitz LE , Broutet N , Taylor M . Lancet Glob Health 2023 11 (9) e1345-e1362 BACKGROUND: The epidemiology of human papillomavirus (HPV) in women has been well documented. Less is known about the epidemiology of HPV in men. We aim to provide updated global and regional pooled overall, type-specific, and age-specific prevalence estimates of genital HPV infection in men. METHODS: We conducted a systematic review and meta-analysis to assess the prevalence of genital HPV infection in the general male population. We searched Embase, Ovid MEDLINE, and the Global Index Medicus for studies published between Jan 1, 1995, and June 1, 2022. Inclusion criteria were population-based surveys in men aged 15 years or older or HPV prevalence studies with a sample size of at least 50 men with no HPV-related pathology or known risk factors for HPV infection that collected samples from anogenital sites and used PCR or hybrid capture 2 techniques for HPV DNA detection. Exclusion criteria were studies conducted among populations at increased risk of HPV infection, exclusively conducted among circumcised men, and based on urine or semen samples. We screened identified reports and extracted summary-level data from those that were eligible. Data were extracted by two researchers independently and reviewed by a third, and discrepancies were resolved by consensus. We extracted only data on mucosal α-genus HPVs. Global and regional age-specific prevalences for any HPV, high-risk (HR)-HPV, and individual HPV types were estimated using random-effects models for meta-analysis and grouped by UN Sustainable Development Goals geographical classification. FINDINGS: We identified 5685 publications from database searches, of which 65 studies (comprising 44 769 men) were included from 35 countries. The global pooled prevalence was 31% (95% CI 27-35) for any HPV and 21% (18-24) for HR-HPV. HPV-16 was the most prevalent HPV genotype (5%, 95% CI 4-7) followed by HPV-6 (4%, 3-5). HPV prevalence was high in young adults, reaching a maximum between the ages of 25 years and 29 years, and stabilised or slightly decreased thereafter. Pooled prevalence estimates were similar for the UN Sustainable Development Goal geographical regions of Europe and Northern America, Sub-Saharan Africa, Latin America and the Caribbean, and Australia and New Zealand (Oceania). The estimates for Eastern and South-Eastern Asia were half that of the other regions. INTERPRETATION: Almost one in three men worldwide are infected with at least one genital HPV type and around one in five men are infected with one or more HR-HPV types. Our findings show that HPV prevalence is high in men over the age of 15 years and support that sexually active men, regardless of age, are an important reservoir of HPV genital infection. These estimates emphasise the importance of incorporating men in comprehensive HPV prevention strategies to reduce HPV-related morbidity and mortality in men and ultimately achieve elimination of cervical cancer and other HPV-related diseases.

Epidemiologic and clinical features of mpox in adults aged >50 years - United States, May 2022-May 2023
Eustaquio PC , Salmon-Trejo LAT , McGuire LC , Ellington SR . MMWR Morb Mortal Wkly Rep 2023 72 (33) 893-896 During May 2022-May 2023, approximately 30,000 mpox cases were reported in the United States, predominantly among young adult men. Persons aged >50 years might experience more severe mpox disease because of a higher prevalence of comorbidities. Conversely, they could have residual protection from childhood smallpox vaccination against monkeypox virus infection and severe mpox, as has been suggested by investigation of some previous mpox outbreaks. To examine the characteristics of mpox cases among adults aged >50 years, analysts compared mpox epidemiology and clinical outcomes among all adults aged ≥18 years, by age group. Further, outcomes were compared among adults aged >50 years by JYNNEOS vaccination status. During May 10, 2022-May 17, 2023, among 29,984 adults with probable or confirmed mpox reported to CDC, 2,909 (9.7%) were aged >50 years, 96.3% of whom were cisgender men. Compared with adults aged 18-50 years, adults aged >50 years had higher prevalences of immunocompromising conditions (p<0.001) and HIV infection (p<0.001). Among adults with mpox aged >50 years, 27.6% had received JYNNEOS vaccination; this group had lower prevalences of constitutional symptoms (p<0.001), pruritus (p<0.001), and hospitalization (p = 0.002) compared with those who had not received JYNNEOS vaccine. Currently recommended JYNNEOS vaccination among all adults at risk for mpox should be encouraged, irrespective of childhood smallpox vaccination status. |
Is the USA on track to end the HIV epidemic
Guilamo-Ramos V , Thimm-Kaiser M , Benzekri A . Lancet HIV 2023 10 (8) e552-e556 Despite progress in reducing new HIV infections in the USA, publicly available data suggest that new HIV infections continue to occur at an alarming rate. In this Viewpoint, we highlight the regularity with which the existing systems for HIV prevention and treatment delivery in the USA fail and the clearly inequitable effect of the systems' failure among several priority populations of the Ending the HIV Epidemic (EHE) initiative. Existing data cast doubt on whether the current EHE efforts will suffice to achieve its 2030 goal of reducing annual new HIV infections to fewer than 3000. We outline future directions in four priority areas to regain lost ground in pursuit of the 2030 EHE goals: reducing the stigma affecting people living with and most at risk of HIV; broadening the HIV workforce; mitigating harmful social determinants of health; and recommitting and reinvesting in health in the USA more broadly. |

Lancet Infect Dis 2023 23 (10) 1111-1112 Ebola virus disease (EVD) caused by Ebola virus species Zaire ebolavirus (EBOV) is a major global health challenge causing sporadic outbreaks with high mortality. The minimum incubation period of EBOV, or the time from infection with the virus to the development of first symptoms, is thought to be 2 days and was initially established during the first EVD investigation in 1976.1 A published observation from the investigation noted that, “in one case of the disease, the only possible source of infection was contact with a probable case 48 hours before the latter developed symptoms”, and this observation was restated in another publication.2, 3 However, concluding that the minimum incubation period for EBOV is 2 days based on these reports is flawed for several reasons. First, the presumed source of the infection was a probable case of EVD and was not laboratory-confirmed; it is therefore uncertain whether the source truly had EVD. Second, since the report describes the contact between the source and the case occurring before the source developed symptoms, this implies asymptomatic transmission, which has been established to not occur with EBOV.4, 5, 6 Finally, the report's description of 48 h refers to the time between the case's contact with the alleged source and the source's onset of symptoms, which is itself not an incubation period. |

Lavoie MC , Ehoche A , Blanco N , Ahmed El-Imam I , Oladipo A , Dalhatu I , Odafe S , Adebajo S , Ng AH , Rapoport L , Lawton JG , Obanubi C , Onotu D , Patel S , Ikpeazu A , Ashefor G , Adebobola B , Adetinuke Boyd M , Aliyu G , Stafford KA . PLoS One 2023 18 (8) e0284847 BACKGROUND: In Nigeria, results from the pilot of the Test and Treat strategy showed higher loss to follow up (LTFU) among people living with HIV compared to before its implementation. The aim of this evaluation was to assess the effects of antiretroviral therapy (ART) initiation within 14 days on LTFU at 12 months and viral suppression. METHODS: We conducted a retrospective cohort study using routinely collected de-identified patient-level data hosted on the Nigeria National Data Repository from 1,007 facilities. The study population included people living with HIV age ≥15. We used multivariable Cox proportional frailty hazard models to assess time to LTFU comparing ART initiation strategy and multivariable log-binomial regression for viral suppression. RESULTS: Overall, 26,937 (38.13%) were LTFU at 12 months. Among individuals initiated within 14 days, 38.4% were LTFU by 12 months compared to 35.4% for individuals initiated >14 days (p<0.001). In the adjusted analysis, individuals who were initiated ≤14 days after HIV diagnosis had a higher hazard of being LTFU (aHR 1.15, 95% CI 1.10-1.20) than individuals initiated after 14 days of HIV diagnosis. Among individuals with viral load results, 86.2% were virally suppressed. The adjusted risk ratio for viral suppression among individuals who were initiated ≤14 days compared to >14 days was not statistically significant. CONCLUSION: LTFU was higher among individuals who were initiated within 14 days compared to greater than 14 days after HIV diagnosis. There was no difference for viral suppression. The provision of early tailored interventions to support newly diagnosed people living may contribute to reducing LTFU. |
High PrEP uptake, adherence, persistence and effectiveness outcomes among young Thai men and transgender women who sell sex in Bangkok and Pattaya, Thailand: findings from the open-label combination HIV prevention effectiveness (COPE) study

Lancet Reg Health Southeast Asia 2023 15 100217 BACKGROUND: Daily oral pre-exposure prophylaxis (PrEP) is effective in preventing HIV infection, but no study has evaluated combination prevention interventions with PrEP for transgender women (TGW) and men who have sex with men (MSM) who sell sex. METHODS: The Combination Prevention Effectiveness (COPE) study was a community-based, non-randomized implementation study in Bangkok and Pattaya, Thailand. Participants were HIV-negative MSM and TGW aged 18-26 years who reported exchanging sex with men in the prior 12 months and who met 2014 U.S. Public Health Service PrEP eligibility criteria. The intervention included quarterly HIV testing, semiannual testing for sexually transmitted infections, provision of condoms with lubricant, and the opportunity to initiate or end daily oral PrEP use at any time during study participation. Participants taking PrEP received monthly adherence counseling and short message service reminders. The primary outcome was HIV incidence rate ratio (IRR) on PrEP vs. not on PrEP. Secondary outcomes were PrEP initiation, PrEP use at 12 months, and PrEP adherence. FINDINGS: From October 2017 to August 2019, 846 participants were enrolled: 531 (62.8%) immediately initiated PrEP; 104 (12.3%) subsequently initiated PrEP, and 211 (24.9%) never initiated PrEP. Among those initiating PrEP within 30 days of enrollment; 85.9% were on PrEP at the 12-months. When taking PrEP, participants reported adherent PrEP use at 94.2% of quarterly assessments. Ten HIV seroconversions occurred without PrEP use (incidence rate [IR] = 3.42 per 100 person-years [PY]; 95% CI = 1.64-6.30), while zero cases occurred with PrEP use (IR = 0.0 per 100PY; 95% CI = 0.0-0.62), with IRR = 0.0 (95% CI = 0.0-0.22; p < 0.001). INTERPRETATION: Young Thai MSM and TGW who exchange sex can have high PrEP uptake, persistence and adherence, and low HIV incidence when offered in supportive community-based settings.

Variability and longitudinal trajectories of phthalate and replacement biomarkers across pregnancy in the human placenta and phthalates study
Rosen EM , Stevens DR , McNell EE , Wood ME , Engel SM , Keil AP , Calafat AM , Botelho JC , Sinkovskaya E , Przybylska A , Saade G , Abuhamad A , Ferguson KK . Environ Sci Technol 2023 57 (35) 13036-13046 Human exposure to phthalates is widespread, but assessment of variability across pregnancy has been hampered by short half-lives of phthalate biomarkers and a few repeated measures in prior studies. We aimed to characterize the variability and longitudinal profiles of phthalate and replacement biomarkers across pregnancy. Within the Human Placenta and Phthalates Study, 303 pregnant women provided urine samples at up to 8 visits across gestation. Concentrations of 14 metabolites of phthalates and 4 metabolites of replacements were quantified in each sample, and subject-specific averages within each trimester were calculated. We examined variability in individual biomarker concentrations across the 8 visits, within trimesters, and across trimester-specific averages using intraclass correlation coefficients (ICCs). To explore longitudinal exposure biomarker profiles, we applied group-based trajectory modeling to trimester-specific averages over pregnancy. Pooling multiple visits into trimester-specific averages improved the ICCs for all biomarkers. Most biomarkers generally showed stable concentrations across gestation, i.e., high-, medium-, and low-concentration profiles, with small proportions of participants falling into the "high"-exposure groups. Variability over pregnancy is likely attributable to random fluctuations around a baseline exposure rather than true changes in concentrations over time. |
Estimating excess mortality during the COVID-19 pandemic from a population-based infectious disease surveillance in two diverse populations in Kenya, March 2020-December 2021
Oduor C , Audi A , Kiplangat S , Auko J , Ouma A , Aol G , Nasimiyu C , Agogo GO , Lo T , Munyua P , Herman-Roloff A , Bigogo G , Munywoki PK . PLOS Glob Public Health 2023 3 (8) e0002141 Robust data on the impact of the COVID-19 pandemic on mortality in Africa are relatively scarce. Using data from two well-characterized populations in Kenya we aimed to estimate excess mortality during the COVID-19 pandemic period. The mortality data arise from an ongoing population-based infectious disease surveillance (PBIDS) platform, which has been operational since 2006 in rural western Kenya (Asembo, Siaya County) and an urban informal settlement (Kibera, Nairobi County), Kenya. PBIDS participants were regularly visited at home (2-3 times a year) by field workers who collected demographic data, including deaths. In addition, verbal autopsy (VA) interviews for all identified deaths are conducted. We estimated all-cause and cause-specific mortality rates before and during the height of the COVID-19 pandemic, and we compared associated mortality rates between the periods using incidence rate ratios. Excess deaths during the COVID-19 period were also estimated by modelling expected deaths in the absence of COVID-19 by applying a negative binomial regression model on historical mortality data from January 2016. Overall and monthly excess deaths were determined using the P-score metric. Spearman correlation was used to assess whether there is a relationship between the generated P-score and COVID-19 positivity rate. The all-cause mortality rate was higher during the COVID-19 period compared to the pre-COVID-19 period in Asembo [9.1 (95% CI, 8.2-10.0) vs. 7.8 (95% CI, 7.3-8.3) per 1000 person-years of observation, pyo]. In Kibera, the all-cause mortality rate was slightly lower during the COVID-19 period compared to the pre-COVID-19 period [2.6 (95% CI, 2.2-3.2 per 1000 pyo) vs. 3.1; 95% CI, 2.7-3.4 per 1000 pyo)]. An increase in all-cause mortality was observed (incidence rate ratio, IRR, 1.16; 95% CI, 1.04-1.31) in Asembo, unlike in Kibera (IRR, 0.88; 95% CI, 0.71-1.09). The notable increase in mortality rate in Asembo was observed among persons aged 50 to 64 years (IRR, 2.62; 95% CI, 1.95-3.52), persons aged 65 years and above (5.47; 95% CI, 4.60-6.50) and among females (IRR, 1.25; 95% CI, 1.07-1.46). These age and gender differences were not observed in Kibera. We observed an increase in the mortality rate due to acute respiratory infection, including pneumonia (IRR, 1.45;95% CI, 1.03-2.04), and a reduction in the mortality rate due to pulmonary tuberculosis (IRR, 0.22; 95% CI, 0.05-0.87) among older children and adults in Asembo. There was no statistically significant change in mortality rates due to leading specific causes of death in Kibera. Overall, during the COVID-19 period observed deaths were higher than expected deaths in Asembo (P-score = 6.0%) and lower than expected in Kibera (P-score = -22.3%).Using well-characterized populations in the two diverse geographic locations, we demonstrate a heterogenous impact of the COVID-19 pandemic on all-cause and cause-specific mortality rates in Kenya. We observed more deaths than expected during the COVID-19 period in our rural site in western Kenya contrary to the urban site in Nairobi, the capital city in Kenya. |
Modeling poliovirus transmission and responses in New York State
Thompson KM , Kalkowska DA , Routh JA , Brenner IR , Rosenberg ES , Zucker JR , Langdon-Embry M , Sugerman DE , Burns CC , Badizadegan K . J Infect Dis 2023 BACKGROUND: In July 2022, New York State (NYS) reported a case of paralytic polio in an unvaccinated young adult, and subsequent wastewater surveillance confirmed sustained local transmission of type 2 vaccine-derived poliovirus (VDPV2) in NYS with genetic linkage to the paralyzed patient. METHODS: We adapted an established poliovirus transmission and oral poliovirus vaccine (OPV) evolution model to characterize dynamics of poliovirus transmission in NYS, including consideration of the immunization activities performed as part of the declared state of emergency. RESULTS: Despite sustained transmission of imported VDPV2 in NYS involving potentially thousands of individuals (depending on seasonality, population structure and mixing assumptions) in 2022, the expected number of additional paralytic cases in years 2023 and beyond is small (less than 0.5). However, continued transmission and/or reintroduction of poliovirus into NYS and other populations remains a possible risk in communities that do not achieve and maintain high immunization coverage. CONCLUSION: In countries such as the US that use only inactivated poliovirus vaccine, even with high average immunization coverage, imported polioviruses may circulate and pose a small but non-zero risk of causing paralysis in non-immune individuals. |
Understanding COVID-19 vaccine hesitancy among K-12 staff, parents, and students: District of Columbia, February to April, 2022
Mark-Carew M , van Zyl A , Tatti KM , Chong M , Rose C , Sifre K , Jarris D , Still W , Aynalem G , Welton M , Thomas ES , Hall L , Samson ME . J Sch Health 2023 93 (12) 1079-1090 OBJECTIVE: Despite widespread availability of COVID-19 vaccines, millions of Americans have not received the recommended vaccine doses. In the District of Columbia (DC), COVID-19 vaccination rates are lowest among residents who are Non-Hispanic (NH) Black and among school-aged children. We assessed COVID-19 vaccine hesitancy among staff and parents of students in DC K-12 public and public charter schools. METHODS: We conducted a telephone-based survey from February 6 to April 16, 2022 to staff, students, and parents of students who participated in school-based COVID-19 screening testing. COVID-19-related survey items included: vaccination status, reasons for not getting vaccinated, perceived vaccine access, and trusted COVID-19 information sources. Utilizing time-to-event analyses, we evaluated differences across demographic groups. RESULTS: The interview response rate was 25.8% (308/1193). Most unvaccinated participants were NH Black and ages 5 to 11 years. Median time from vaccine eligibility to uptake was 236 days for NH Black participants vs. 10 days for NH White participants. Vaccine safety was the top concern among unvaccinated participants. Government and healthcare providers were the most trusted COVID-19 information sources. CONCLUSIONS: Differences in timing of vaccine uptake among respondents and greater vaccine hesitancy among NH Black participants compared to other racial/ethnic groups highlight a need for continued tailored outreach and communication using trusted sources to convey the importance, benefits, and safety of COVID-19 vaccination. |
Cost-outcome analysis of HIV testing and counseling, linkage, and defaulter tracing services in Bukoba, Tanzania
Suraratdecha C , MacKellar D , Steiner C , Rwabiyago OE , Cham HJ , Msumi O , Maruyama H , Kundi G , Byrd J , Weber R , Mkemwa G , Kazaura K , Justman J , Rwebembera A . AIDS Care 2023 1-8 Effective services along the HIV continuum of care from HIV testing and counseling to linkage, and from linkage to antiretroviral therapy (ART) initiation and retention, are key to improved health outcomes of persons living with HIV. A comprehensive analysis of the costs and outcomes of cascade services is needed to help allocate and prioritize resources to achieve UNAIDS targets. We evaluated the costs and population-level impact of a community-wide, integrated scale-up of testing, linkage, and defaulter-tracing programs implemented in Bukoba Municipal Council, Tanzania. Costs per identified HIV-positive client for provider-initiated, and home- and venue-based testing and counseling were $92.64 United States dollars (USD), $256.33 USD, and $281.57 USD, respectively. Costs per patient linked to HIV care and ART were $47.69 USD and $74.12 USD, respectively, during all ART-eligibility periods combined. Costs per defaulter traced and returned to HIV care were $47.56 USD and $206.77 USD, respectively. The provider-initiated testing and counseling was the most cost-effective modality. Testing approaches targeted to populations groups and geographic location with high testing positivity rates may improve the overall efficiency of testing services. The expansion of ART eligibility criteria and high linkage rate also result in efficiency gains and economies of scale of linkage services. |
New York State, New York City, New Jersey, Puerto Rico, and the US Virgin Islands' Health Department experiences promoting health equity during the initial COVID-19 Omicron variant period, 2021-2022
Cox H , Gebru Y , Horter L , Palomeque FS , Myers K , Stowell D , Easterling T , de Noguera NS , Medina-Forrester A , Bravo J , Pérez S , Chaparro J , Ekpo LP , Cranford H , Santibañez S , Valencia D . Health Secur 2023 21 S25-S34 In this case study, we aim to understand how health departments in 5 US jurisdictions addressed health inequities and implemented strategies to reach populations disproportionately affected by COVID-19 during the initial Omicron variant period. We used qualitative methods to examine health department experiences during the initial Omicron surge, from November 2021 to April 2022, assessing successful interventions, barriers, and lessons learned from efforts to promote health equity. Our findings indicate that government leadership supported prioritizing health equity from the beginning of the pandemic, seeing it as a need and vital part of the response framework. All jurisdictions acknowledged the historical trauma and distrust of the government. Health departments found that collaborating and communicating with trusted community leaders helped mitigate public distrust. Having partnerships, resources, and infrastructure in place before the pandemic facilitated the establishment of equity-focused COVID-19 response activities. Finally, misinformation about COVID-19 was a challenge for all jurisdictions. Addressing the needs of diverse populations involves community-informed decisionmaking, diversity of thought, and delivery measures that are tailored to the community. It is imperative to expand efforts to reduce and eliminate health inequities to ensure that individuals and communities recover equitably from the effects of COVID-19. |

J Racial Ethn Health Disparities 2023 OBJECTIVES: To examine disparities by sex, age group, and race and ethnicity in COVID-19 confirmed cases, hospitalizations, and deaths among incarcerated people and staff in correctional facilities. METHODS: Six U.S. jurisdictions reported data on COVID-19 confirmed cases, hospitalizations, and deaths stratified by sex, age group, and race and ethnicity for incarcerated people and staff in correctional facilities during March 1- July 31, 2020. We calculated incidence rates and rate ratios (RR) and absolute rate differences (RD) by sex, age group, and race and ethnicity, and made comparisons to the U.S. general population. RESULTS: Compared with the U.S. general population, incarcerated people and staff had higher COVID-19 case incidence (RR = 14.1, 95% CI = 13.9-14.3; RD = 6,692.2, CI = 6,598.8-6,785.5; RR = 6.0, CI = 5.7-6.3; RD = 2523.0, CI = 2368.1-2677.9, respectively); incarcerated people also had higher rates of COVID-19-related deaths (RR = 1.6, CI = 1.4-1.9; RD = 23.6, CI = 14.9-32.2). Rates of COVID-19 cases, hospitalizations, and deaths among incarcerated people and corrections staff differed by sex, age group, and race and ethnicity. The COVID-19 hospitalization (RR = 0.9, CI = 0.8-1.0; RD = -48.0, CI = -79.1- -16.8) and death rates (RR = 0.8, CI = 0.6-1.0; RD = -11.8, CI = -23.5- -0.1) for Black incarcerated people were lower than those for Black people in the general population. COVID-19 case incidence, hospitalizations, and deaths were higher among older incarcerated people, but not among staff. CONCLUSIONS: With a few exceptions, living or working in a correctional setting was associated with higher risk of COVID-19 infection and resulted in worse health outcomes compared with the general population; however, Black incarcerated people fared better than their U.S. general population counterparts. |

Infect Control Hosp Epidemiol 2023 1-10 OBJECTIVE: Studies evaluating the incidence, source, and preventability of hospital-onset bacteremia and fungemia (HOB), defined as any positive blood culture obtained after 3 calendar days of hospital admission, are lacking in low- and middle-income countries (LMICs). DESIGN, SETTING, AND PARTICIPANTS: All consecutive blood cultures performed for 6 months during 2020-2021 in 2 hospitals in India were reviewed to assess HOB and National Healthcare Safety Network (NHSN) reportable central-line-associated bloodstream infection (CLABSI) events. Medical records of a convenience sample of 300 consecutive HOB events were retrospectively reviewed to determine source and preventability. Univariate and multivariable logistic regression analyses were performed to identify factors associated with HOB preventability. RESULTS: Among 6,733 blood cultures obtained from 3,558 hospitalized patients, there were 409 and 59 unique HOB and NHSN-reportable CLABSI events, respectively. CLABSIs accounted for 59 (14%) of 409 HOB events. There was a moderate but non-significant correlation (r = 0.51; P = .070) between HOB and CLABSI rates. Among 300 reviewed HOB cases, CLABSIs were identified as source in only 38 (13%). Although 157 (52%) of all 300 HOB cases were potentially preventable, CLABSIs accounted for only 22 (14%) of these 157 preventable HOB events. In multivariable analysis, neutropenia, and sepsis as an indication for blood culture were associated with decreased odds of HOB preventability, whereas hospital stay ≥7 days and presence of a urinary catheter were associated with increased likelihood of preventability. CONCLUSIONS: HOB may have utility as a healthcare-associated infection metric in LMIC settings because it captures preventable bloodstream infections beyond NHSN-reportable CLABSIs. |

(Quality of evidence: | LOW) | 7 Ensure that sufficiently trained HCP and technology resources are available to support surveillance for catheter use and outcomes. (Quality of evidence: | LOW) | 8 Perform surveillance for CAUTI if indicated based on facility risk assessment or regulatory requirements. (Quality of evidence: LOW) | 9 Standardize urine culturing by adapting an institutional protocol for appropriate indications for urine cultures in patients with and without indwelling | catheters. Consider incorporating these indications into the electronic medical record, and review indications for ordering urine cultures in the CAUTI | risk assessment.

Mpox vaccine acceptability among people experiencing homelessness in San Francisco - October-November 2022
Filardo TD , Prasad N , Waddell CJ , Persad N , Pellegrini GJ Jr , Borne D , Janssen J , Bejarano A , Marx GE , Mosites E . Vaccine 2023 41 (39) 5673-5677 Mpox has affected many communities in the United States (U.S.), including people experiencing homelessness (PEH). Mpox vaccination has been an important tool to disrupt transmission and protect communities at risk of infection. To better understand mpox vaccine knowledge and attitudes, we surveyed 273 PEH and people accessing homeless service sites in San Francisco. Among 64 participants previously offered mpox vaccination, 38 (59 %) had received the vaccine. Among 209 participants not previously offered mpox vaccination, 108 (52 %) reported they would receive the vaccine. Vaccine acceptance was higher among transgender female participants and among male participants who reported male sex partner preference (MSM). Half of participants who declined vaccination identified that perception of personal risk and vaccine education may increase their likelihood of receiving an mpox vaccine. Leveraging trusted information sources to provide risk communication and vaccine education may increase vaccine uptake among PEH. |
Influenza vaccination among pregnant people before and during the coronavirus disease 2019 (COVID-19) pandemic
Irving SA , Crane B , Weintraub E , Kauffman TL , Brooks N , Patel SA , Razzaghi H , Belongia EA , Daley MF , Getahun D , Glenn SC , Hambidge SJ , Jackson LA , Kharbanda E , Klein NP , Zerbo O , Naleway AL . Obstet Gynecol 2023 142 (3) 636-639 There are limited data on influenza vaccination coverage among pregnant people in the United States during the coronavirus disease 2019 (COVID-19) pandemic. Within the Vaccine Safety Datalink, we conducted a retrospective cohort study to examine influenza vaccination coverage during the 2016-2017 through the 2021-2022 influenza seasons among pregnant people aged 18-49 years. Using influenza vaccines administered through March each season, we assessed crude coverage by demographic and clinical characteristics. Annual influenza vaccination coverage increased from the 2016-2017 season (63.0%) to a high of 71.0% in the 2019-2020 season. After the start of the COVID-19 pandemic, it decreased to a low of 56.4% (2021-2022). In each of the six seasons, coverage was lowest among pregnant people aged 18-24 years and among non-Hispanic Black pregnant people. The 2021-2022 season had the lowest coverage across all age and race and ethnicity groups. The recent decreases highlight the need for continued efforts to improve coverage among pregnant people. |
Simultaneous administration of mRNA COVID-19 bivalent booster and influenza vaccines
Kenigsberg TA , Goddard K , Hanson KE , Lewis N , Klein N , Irving SA , Naleway AL , Crane B , Kauffman TL , Xu S , Daley MF , Hurley LP , Kaiser R , Jackson LA , Jazwa A , Weintraub ES . Vaccine 2023 41 (39) 5678-5682 The U.S. Food and Drug Administration authorized use of mRNA COVID-19 bivalent booster vaccines on August 31, 2022. Currently, CDC's clinical guidance states that COVID-19 and other vaccines may be administered simultaneously. At time of authorization and recommendations, limited data existed describing simultaneous administration of COVID-19 bivalent booster and other vaccines. We describe simultaneous influenza and mRNA COVID-19 bivalent booster vaccine administration between August 31-December 31, 2022, among persons aged ≥6 months in the Vaccine Safety Datalink (VSD) by COVID-19 bivalent booster vaccine type, influenza vaccine type, age group, sex, and race and ethnicity. Of 2,301,876 persons who received a COVID-19 bivalent booster vaccine, 737,992 (32.1%) received simultaneous influenza vaccine, majority were female (53.1%), aged ≥18 years (91.4%), and non-Hispanic White (55.7%). These findings can inform future VSD studies on simultaneous influenza and COVID-19 bivalent booster vaccine safety and coverage, which may have implications for immunization service delivery. |

MMWR Morb Mortal Wkly Rep 2023 72 (33) 886-892 On June 19, 2022, the original monovalent mRNA COVID-19 vaccines were approved as a primary series for children aged 6 months-4 years (Pfizer-BioNTech) and 6 months-5 years (Moderna) based on safety, immunobridging, and limited efficacy data from clinical trials. On December 9, 2022, CDC expanded recommendations for use of updated bivalent vaccines to children aged ≥6 months. mRNA COVID-19 vaccine effectiveness (VE) against emergency department or urgent care (ED/UC) encounters was evaluated within the VISION Network during July 4, 2022-June 17, 2023, among children with COVID-19-like illness aged 6 months-5 years. Among children aged 6 months-5 years who received molecular SARS-CoV-2 testing during August 1, 2022-June 17, 2023, VE of 2 monovalent Moderna doses against ED/UC encounters was 29% (95% CI = 12%-42%) ≥14 days after dose 2 (median = 100 days after dose 2; IQR = 63-155 days). Among children aged 6 months-4 years with a COVID-19-like illness who received molecular testing during September 19, 2022-June 17, 2023, VE of 3 monovalent Pfizer-BioNTech doses was 43% (95% CI = 17%-61%) ≥14 days after dose 3 (median = 75 days after dose 3; IQR = 40-139 days). Effectiveness of ≥1 bivalent dose, comparing children with at least a complete primary series and ≥1 bivalent dose to unvaccinated children, irrespective of vaccine manufacturer, was 80% (95% CI = 42%-96%) among children aged 6 months-5 years a median of 58 days (IQR = 32-83 days) after the dose. All children should stay up to date with recommended COVID-19 vaccines, including initiation of COVID-19 vaccination immediately when they are eligible. |
Progress toward poliomyelitis eradication - Pakistan, January 2022-June 2023
Mbaeyi C , Baig S , Safdar RM , Khan Z , Young H , Jorba J , Wadood ZM , Jafari H , Alam MM , Franka R . MMWR Morb Mortal Wkly Rep 2023 72 (33) 880-885 Since the establishment of the Global Polio Eradication Initiative in 1988, Pakistan remains one of only two countries (along with Afghanistan) with continued endemic transmission of wild poliovirus (WPV). This report describes Pakistan's progress toward polio eradication during January 2022-June 2023. During 2022, Pakistan reported 20 WPV type 1 (WPV1) cases, all of which occurred within a small geographic area encompassing three districts in south Khyber Pakhtunkhwa. As of June 23, only a single WPV1 case from Bannu district in Khyber Pakhtunkhwa province has been reported in 2023, compared with 13 cases during the same period in 2022. In addition, 11 WPV1 isolates have been reported from various environmental surveillance (ES) sewage sampling sites to date in 2023, including in Karachi, the capital of the southern province of Sindh. Substantial gaps remain in the quality of supplementary immunization activities (SIAs), especially in poliovirus reservoir areas. Despite the attenuation and apparently limited geographic scope of poliovirus circulation in Pakistan, the isolation of WPV1 from an ES site in Karachi is cause for concern about the actual geographic limits of transmission. Interrupting WPV1 transmission will require meticulous tracking and sustained innovative efforts to vaccinate children who are regularly missed during SIAs and rapidly responding to any new WPV1 isolations. |
Perspectives on advancing countermeasures for filovirus disease: Report from a multi-sector meeting
Sprecher A , Cross R , Marzi A , Martins KA , Wolfe D , Montgomery JM , Spiropoulou CF , Cihlar T , Ahuka-Mundeke S , Nyhuis T , Teicher C , Crozier I , Strong J , Kobinger G , Woolsey C , Geisbert TW , Feldmann H , Muyembe JJ . J Infect Dis 2023 228 S474-S478 Although there are now approved treatments and vaccines for Ebola virus disease (EVD), the case fatality of EVD remains unacceptably high even when treated with the newly approved therapeutics; furthermore, these countermeasures are not expected to be effective against disease caused by other filoviruses. A meeting of subject matter experts from public health, research, and countermeasure development agencies and manufacturers was held during the 10th International Filovirus Symposium to discuss strategies to address these gaps, including how newer countermeasures could be advanced for field readiness. Several investigational therapeutics, vaccine candidates, and combination strategies were presented. In all, a common theme emerged: the greatest challenge to completing development was the implementation of well-designed clinical trials of safety and efficacy during filovirus disease outbreaks. These outbreaks are usually of short duration, providing but a brief opportunity for trials to be launched, and have too few cases to allow for full enrollment during a single outbreak, so clinical trials will necessarily need to span multiple outbreaks which may occur in a number of at-risk countries. Preparing for this will require agreed-upon common protocols for trials intended to bridge multiple outbreaks across all at-risk countries. A multi-national research consortium including, and led by, at-risk countries would be an ideal mechanism to negotiate agreement on protocol design and coordinate preparation. Discussion participants recommended a follow-up meeting be held in Africa with national public health and research agencies from at-risk countries to establish such a consortium. |
QuickStats: Percentage* of children and adolescents aged ≤ 17 years who had ever received a diagnosis of concussion or brain injury,(†) by sex and age group - National Health Interview Survey,(§) United States, 2022
Elgaddal N , Black LI . MMWR Morb Mortal Wkly Rep 2023 72 (33) 899 In 2022, 2.3 million (3.2%) children and adolescents aged ≤17 years had ever received a diagnosis of a concussion or brain injury. Diagnosis of a concussion or brain injury increased with age, from 1.0% among those aged 0–5 years to 2.3% among those aged 6–11 years, and 5.9% among those aged 12–17 years. Percentages were higher for boys than girls overall (3.7% versus 2.6%), among those aged 6–11 years (3.0% versus 1.6%), and those aged 12–17 years (6.9% versus 4.9%) but were similar by sex among those aged 0–5 years (1.0% versus 1.1%). |
Reproductive coercion and intimate partner violence perpetration among young adult males
Muñoz EA , Le VD , Shorey RC , Temple JR . Violence Against Women 2023 29 (14) 10778012231196059 Reproductive coercion is any behavior that attempts to control the autonomous reproductive decision-making of an intimate partner. Very little research has focused on males who perpetrate reproductive coercion. Using a diverse community sample of young adults, we examined the prevalence of lifetime reproductive coercion perpetration and its relationship with other forms of intimate partner violence (IPV). Results demonstrated that approximately 6.4% of the men reported perpetrating reproductive coercion in their lifetime. Chi-square analyses demonstrated that men who reported sexual (16.2%), physical (11.1%), or psychological (59.1%) IPV perpetration, relative to men who did not, reported a significantly higher prevalence of reproductive coercion perpetration. |
Prevalence of and factors associated with peer emotional and physical violence among youth ages 13-17 in Cote d'Ivoire
Ratto J , Dobash D , Seya S , Trika B , Kamagate F , Chiang L . Child Abuse Negl 2023 145 106380 BACKGROUND: Peer violence during childhood is associated with negative outcomes. Data are limited on its associated factors in sub-Saharan Africa. OBJECTIVE: This study assesses the prevalence and factors associated with peer emotional and physical violence among children and adolescents aged 13-17years in Côte d'Ivoire. PARTICIPANTS AND SETTING: Data from the 2018 Côte d'Ivoire Violence Against Children and Youth Survey (VACS) were used to examine peer emotional and physical violence victimization. VACS is a national cross-sectional household survey of females and males aged 13-24years. METHODS: Data included physical, emotional, and sexual violence and socioeconomic, demographic, and relationship factors. We computed the adjusted odds ratios (AOR) and confidence interval (CI) for associated factors adjusted for food insecurity and rural or urban setting. RESULTS: Thirty-one percent of females and 46.7 % of males experienced lifetime peer physical violence and 36.8 % of females and 40.2 % of males experienced peer emotional violence in the past 12 months. Witnessing violence in the home towards the mother (female AOR 1.2, CI 1.0-1.3); male AOR 1.4, CI 1.2-1.6) and witnessing violence in the home towards a sibling (female AOR 1.2, CI 1.1-1.3; male AOR 1.3, CI 1.12-1.4) increased the odds of ever experiencing peer physical violence. In males, not living with their biological mother (AOR 1.2, CI 1.0, 1.4) or biological father (AOR 1.2, CI 1.1-1.3) was associated with ever experiencing peer physical violence. CONCLUSION: Interventions for children and adolescents living without parents and programming focused on education and skills-building may help to reduce peer violence against children in Côte d'Ivoire. |
Association between social vulnerability factors and unintentional fatal injury rates United States, 2015-2019
Wulz AR , Sharpe JD , Miller GF , Wolkin AF . J Saf Res 2023 Background: Differences in social and environmental factors can contribute to disparities in fatal injury rates. The purpose of this study was to examine the relationship between social and environmental factors and unintentional fatal injury across counties in the United States and how this relationship varies by geography. Methods: County-level vital statistics on age-adjusted unintentional fatal injury rates for 20152019 were linked with county-level data from the 2018 Social Vulnerability Index (SVI), a dataset identifying socially vulnerable communities. We conducted linear regression to examine the association between SVI and unintentional fatal injury, overall and by Census region/division. We mapped county-level data for SVI and unintentional fatal injury rates in bivariate choropleth maps using quartiles. Results: SVI was positively associated with unintentional fatal injury ( = 18.29, p < 0.001) across U.S. counties. The geographic distribution of SVI and unintentional fatal injury rates varied spatially and substantially for U.S. counties, with counties in the South and West regions having the greatest levels of SVI and rates of unintentional fatal injury. Conclusions: Our findings demonstrate that the social vulnerability of counties is associated with unintentional fatal injury rates. Modification of the SVI for injury research could include additional social determinants and exclude variables not applicable to injuries. A modified SVI could inform unintentional injury prevention strategies by prioritizing efforts in areas with high levels of social vulnerability. Practical Applications: This study is the first step in combining the SVI and injury mortality data to provide researchers with an index to investigate upstream factors related to injury. 2023 |

Utilizing recombinant reporter henipaviruses to conduct antiviral screening
Lo MK . Methods Mol Biol 2023 2682 87-92 Spillovers of Nipah virus (NiV) from its pteropid bat reservoir into the human population continue to cause near-annual outbreaks of fatal encephalitis and respiratory disease in Bangladesh and India since its emergence in Malaysia over 20 years ago. The current lack of effective antiviral therapeutics against NiV merits further testing of compound libraries against NiV using rapid quantitative antiviral assays. The development of recombinant henipaviruses expressing reporter fluorescence and/or luminescence proteins has facilitated the screening of such libraries. In this chapter, we provide a basic protocol for both types of reporter viruses. Utilizing these live NiV-based reporter assays requires modest instrumentation and sidesteps the labor-intensive steps associated with traditional cytopathic effect or viral antigen-based assays. |
A revised diagnostic quantitative RT-PCR for the detection of Nipah virus infection
Patel K , Klena J , Lo MK . Methods Mol Biol 2023 2682 25-31 From its discovery in Malaysia in the late 1990s, the spillover of the Nipah virus from its pteropid reservoir into the human population has resulted in sporadic outbreaks of fatal encephalitis and respiratory disease. In this chapter, we revise a previously described quantitative reverse transcription polymerase chain reaction method, which now utilizes degenerate nucleotides at certain positions in the probe and the reverse primer to accommodate the sequence heterogeneity observed within the Nipah henipavirus species. |
Online solid phase extraction high-performance liquid chromatography - Isotope dilution - Tandem mass spectrometry quantification of organophosphate pesticides, synthetic pyrethroids, and selected herbicide metabolites in human urine
Wambua D , Roman W , Vidanage I , Vidal M , Calafat AM , Ospina M . Chemosphere 2023 340 139863 Analytical methods to quantify pesticide biomarkers in human population studies are critical for exposure assessment given the widespread use of pesticides for pest and weed control and their potential for affecting human health. We developed a method to quantify, in 0.2 mL of urine, concentrations of 10 pesticide biomarkers: four organophosphate insecticide metabolites (3,5,6-trichloro-2-pyridinol (TCPy), 2-isopropyl-6-methyl-4-pyrimidinol, para-nitrophenol, malathion dicarboxylic acid); five synthetic pyrethroid insecticide metabolites (4-fluoro-3-phenoxybenzoic acid, 3-phenoxybenzoic acid, cis and trans-3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane carboxylic acid (DCCA), cis-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid); and the herbicide 2,4-dichlorophenoxyacetic acid. The method is based on enzymatic hydrolysis of conjugated urinary metabolites, extraction and pre-concentration of the deconjugated metabolites using automated online solid-phase extraction, and separation and quantification using liquid chromatography-isotope dilution tandem mass spectrometry. Depending on the analyte, method detection limits were 0.1-0.6 ng/mL; mean accuracy, calculated as spike recoveries, was 91-102%, and total precision, given as percent variation coefficient, was 5.9-11.5%. Percent differences associated with three freeze-thaw cycles, 24-h benchtop storage, and short-term processed sample stability were <14%. METHOD: suitability was assessed by recurring successful participation in external quality assessment schemes and by analyzing samples from subjects with suspected exposure to pesticides (n = 40) or who self-reported consuming an organic diet (n = 50). Interquartile ranges were considerably lower for people consuming an organic diet than for those potentially exposed for cis-DCCA (0.37 ng/mL vs 0.75 ng/mL), trans-DCCA (0.88 ng/mL vs 1.78 ng/mL) and TCPy (1.81 ng/mL vs 2.48 ng/mL). This method requires one-fifth of the sample used in our previous method and is suitable for assessing background exposures to select pesticides in large human populations and for studies with limited sample volumes. |

J Pediatric Infect Dis Soc 2023 12 (9) 487-495 BACKGROUND: Adjunctive diagnostic studies (aDS) are recommended to identify occult dissemination in patients with candidemia. Patterns of evaluation with aDS across pediatric settings are unknown. METHODS: Candidemia episodes were included in a secondary analysis of a multicenter comparative effectiveness study that prospectively enrolled participants age 120 days -17 years with invasive candidiasis (predominantly candidemia) from 2014-2017. Ophthalmologic examination, abdominal imaging, echocardiogram, neuroimaging, and lumbar puncture were performed per clinician discretion. aDS performance and positive results were determined per episode, within 30 days from candidemia onset. Associations of aDS performance with episode characteristics were evaluated via mixed effects logistic regression. RESULTS: In 662 pediatric candidemia episodes, 490 (74%) underwent abdominal imaging, 450 (68%) ophthalmologic examination, 426 (64%) echocardiogram, 160 (24%) neuroimaging, and 76 (11%) lumbar puncture; performance of each aDS per episode varied across sites up to 16-fold. Longer durations of candidemia were associated with undergoing ophthalmologic examination, abdominal imaging, and echocardiogram. Immunocompromised status (58% of episodes) was associated with undergoing abdominal imaging (aOR 2.38; 95% CI 1.51-3.74). Intensive care at candidemia onset (30% of episodes) was associated with undergoing echocardiogram (aOR 2.42; 95% CI 1.51-3.88). Among evaluated episodes, positive ophthalmologic examination was reported in 15 (3%), abdominal imaging in 30 (6%), echocardiogram in 14 (3%), neuroimaging in 9 (6%) and lumbar puncture in 3 (4%). CONCLUSIONS: Our findings show heterogeneity in practice, with some clinicians performing aDS selectively, potentially influenced by clinical factors. The low frequency of positive results suggests that targeted application of aDS is warranted. |
The use of saliva samples to test for congenital cytomegalovirus infection in newborns: Examination of false-positive samples associated with donor milk use
Wunderlich W , Sidebottom AC , Schulte AK , Taghon J , Dollard S , Hernandez-Alvarado N . Int J Neonatal Screen 2023 9 (3) A universal screening research study was conducted in six hospitals to identify the clinical sensitivity of polymerase chain reaction (PCR) testing on newborn dried blood spots (DBSs) versus saliva specimens for the diagnosis of congenital cytomegalovirus (cCMV). CMV DNA positive results from DBSs or saliva were confirmed with urine testing. Findings of several false-positive (FP) saliva PCR results prompted an examination of a possible association with donor milk. Documentation of the frequency of positive saliva results, including both true-positive (TP) and FP status from clinical confirmation, occurred. The frequency of donor milk use was compared for TP and FP cases. Of 22,079 participants tested between 2016 and 2022, 96 had positive saliva results, 15 were determined to be FP, 79 TP, and 2 were excluded for incomplete clinical evaluation. Newborn donor milk use was identified for 18 (19.14%) of all the positive saliva screens. Among the 15 FPs, 11 (73.33%) consumed donor milk compared to 7 of the 79 TPs (8.8%) (OR 28.29, 95% CI 7.10-112.73, p < 0.001). While milk bank Holder pasteurization inactivates CMV infectivity, CMV DNA may still be detectable. Due to this possible association, screening programs that undertake testing saliva for CMV DNA may benefit from documenting donor milk use as a potential increased risk for FP results. |
Changes in policy supports for healthy food retailers, farmers markets, and breastfeeding among US municipalities, 2014-2021: National survey of Community-Based Policy and Environmental Supports for Healthy Eating and Active Living (CBS-HEAL)
Onufrak SJ , Moore LV , Pierce SL , MacGowan CA , Galuska DA . Prev Chronic Dis 2023 20 E73 INTRODUCTION: Policies and practices at the local level can help reduce chronic disease risk by providing environments that facilitate healthy decision-making about diet. METHODS: We used data from the 2014 and 2021 National Survey of Community-Based Policy and Environmental Supports for Healthy Eating and Active Living to examine prevalence among US municipalities of policies to support access to healthier food in supermarkets, convenience stores, and farmers markets, as well as policies to support breastfeeding among government employees. Chi-square tests were conducted to compare prevalence estimates from 2021 to 2014 overall and according to municipal characteristics. RESULTS: In 2021, 29% of municipalities had at least 1 policy to encourage full-service grocery stores to open stores, which was not significantly different from 31% in 2014. Prevalence of having at least 1 policy to help corner stores sell healthier foods declined significantly from 13% in 2014 to 9% in 2021. Prevalence of policies providing all local government employees who were breastfeeding breaktime and space to pump breast milk increased significantly from 25% in 2014 to 52% in 2021. The percentage of municipalities that provided 8 or more weeks of paid maternity leave for employees increased significantly from 16% in 2014 to 19% in 2021. CONCLUSION: Prevalence of supports for supermarkets, convenience stores, and farmers markets generally did not increase among US municipalities from 2014 to 2021, while some supports for breastfeeding among municipal employees increased during this time. Opportunities exist to improve municipal-level policies that support healthy eating and breastfeeding among community residents and employees. |
Characterization of inhalation exposures at a wildfire incident during the Wildland Firefighter Exposure and Health Effects (WFFEHE) Study
Navarro KM , Fent K , Mayer AC , Brueck SE , Toennis C , Law B , Meadows J , Sammons D , Brown S . Ann Work Expo Health 2023 67 (8) 1011-1017 Wildland firefighters (WFFs) are exposed to many inhalation hazards working in the wildland fire environment. To assess occupational exposures and acute and subacute health effects among WFFs, the wildland firefighter exposure and health effects study collected data for a 2-year repeated measures study. This manuscript describes the exposure assessment from one Interagency Hotshot Crew (N = 19) conducted at a wildfire incident. Exposures to benzene, toluene, ethylbenzene, xylene isomers, formaldehyde, acetaldehyde, and naphthalene were measured through personal air sampling each work shift. Biological monitoring was done for creatinine-adjusted levoglucosan in urine pre- and post-shift. For 3 days sampling at the wildfire incident, benzene, toluene, ethylbenzene, xylene isomers (m and p, and o) exposure was highest on day 1 (geometric mean [GM] = 0.015, 0.042, 0.10, 0.42, and 0.15 ppm, respectively) when WFFs were not exposed to smoke but used chainsaws to remove vegetation and prepare fire suppression breaks. Exposure to formaldehyde and acetaldehyde was highest on day 2 (GM = 0.03 and 0.036 ppm, respectively) when the WFFs conducted a firing operation and were directly exposed to wildfire smoke. The greatest difference of pre- and post-shift levoglucosan concentrations were observed on day 3 (pre-shift: 9.7 and post-shift: 47 μg/mg creatinine) after WFFs conducted mop up (returned to partially burned area to extinguish any smoldering vegetation). Overall, 65% of paired samples (across all sample days) showed a post-shift increase in urinary levoglucosan and 5 firefighters were exposed to benzene at concentrations at or above the National Institute for Occupational Safety and Health (NIOSH) recommended exposure limit. Our findings further demonstrate that exposure to inhalation hazards is one of many risks that wildland firefighters experience while suppressing wildfires. |
Relationship of personal, situational, and environmental factors to injury experience in commercial fishing
Kincl L , Syron L , Lucas D , Vaughan A , Bovbjerg V . J Safety Res 2023 87 375-381 Introduction: Commercial fishing work involves a variety of activities and is hazardous. While much is understood to mitigate fatalities in this industry, research must further explore nonfatal injury characteristics, factors related to injury, and potential injury prevention strategies. This paper determines if fishing experience is associated with injury risk and explores common work activities associated with injury. Method: Key informant interviews and a survey of fishermen were conducted to refine work activity codes and collect injury experiences. Independent sample t-tests compared the means of the years fishing by injury incident for all crab fishermen then stratified by position. Descriptive statistics explored the nature of injury in relation to work activity. Results: The level of experience was significantly lower for injured fishermen compared to fishermen who reported no injuries, but when stratified by position at the time of the injury, the association of injury to experience was only significant for owners. This stratified result demonstrates that the work activity, rather than experience, drives the apparent relationship of experience to injury. Being tired (24%) and weather (26%) were indicated as contributing factors at the time of injury. Conclusion: Modifying the work environment to better control hazards would benefit all fishermen, regardless of their experience, age, or position. Further work into effective interventions that fishermen would adopt is needed to reduce injury risk. Any formal or informal training of new fishermen should focus on the most hazardous activities, but more experienced fishermen would also benefit. Additionally, effective training or interventions for fatigue management, and decision support tools for weather- and navigation-related decisions would further reduce risk of at sea injuries. Practical Applications: Injury prevention training, for all fishermen, regardless of their position and years of experience, should cover the most hazardous tasks, fatigue risk management strategies, and weather decisions. |
Preventing occupational hearing loss: 50 years of research and recommendations from the National Institute for Occupational Safety and Health
Themann CL , Masterson EA , Peterson JS , Murphy WJ . Semin Hear 2023 44 (4) 351-393 For more than 50 years, the National Institute for Occupational Safety and Health (NIOSH), part of the United States (U.S.) Centers for Disease Control and Prevention (CDC), has been actively working to reduce the effects of noise and ototoxic chemicals on worker hearing. NIOSH has pioneered basic and applied research on occupational hearing risks and preventive measures. The Institute has issued recommendations and promoted effective interventions through mechanisms ranging from formal criteria documents to blogs and social media. NIOSH has conducted surveillance and published statistics to guide policy and target prevention efforts. Over the past five decades, substantial progress has been made in raising awareness of noise as a hazard, reducing the risk of occupational hearing loss, improving the use of hearing protection, and advancing measurement and control technologies. Nevertheless, noise remains a prevalent workplace hazard and occupational hearing loss is still one of the most common work-related conditions. NIOSH continues to work toward preventing the effects of noise and ototoxicants at work and has many resources to assist audiologists in their hearing loss prevention efforts. © 2023 Thieme Medical Publishers, Inc..

Audiological tests used in the evaluation of the effects of solvents on the human auditory system: A mixed methods review
Roggia SM , Zucki F , Fuente A , Lacerda ABMD , Gong W , Carlson K , Morata TC . Semin Hear 2023 44 (4) 437-469 This study aimed to scope the literature, identify knowledge gaps, appraise results, and synthesize the evidence on the audiological evaluation of workers exposed to solvents. We searched Medline, PubMed, Embase, CINAHL, and NIOSHTIC-2 up to March 22, 2021. Using Covidence, two authors independently assessed study eligibility, risk of bias, and extracted data. National Institute of Health Quality Assessment Tools was used in the quality evaluation of included studies; the Downs and Black checklist was used to assess the risk of bias. Of 454 located references, 37 were included. Twenty-five tests were studied: two tests to measure hearing thresholds, one test to measure word recognition in quiet, six electroacoustic procedures, four electrophysiological tests, and twelve behavioral tests to assess auditory processing skills. Two studies used the Amsterdam Inventory for Auditory Disability and Handicap. The quality of individual studies was mostly considered moderate, but the overall quality of evidence was considered low. The discrepancies between studies and differences in the methodologies/outcomes prevent recommending a specific test battery to assess the auditory effects of occupational solvents. Decisions on audiological tests for patients with a history of solvent exposures require the integration of the most current research evidence with clinical expertise and stakeholder perspectives. © 2023 Thieme Medical Publishers, Inc..

The quality of malaria case management in different transmission settings in Tanzania mainland, 2017-2018
Hussein AK , Tarimo D , Reaves EJ , Chacky F , Abade AM , Mwalimu CD , Mohamed A , Nasser A , Kishimba RS . PLOS Glob Public Health 2023 3 (8) e0002318 Tanzania is undergoing an epidemiological transition for malaria transmission with some areas of the country having <10% (hypoendemic) and other areas 10% - 50% malaria prevalence (mesoendemic). It is not known whether there is a difference in the quality of malaria case management based on endemicity in Tanzania mainland. We examined the influence of endemicity on the quality of malaria case management at health facilities. We conducted a cross-sectional analysis of 1713 health facilities in Tanzania mainland, using data collected by the National Malaria Control Program through an assessment tool to evaluate quality of malaria case management. The data was gathered from September 2017 to December 2018. Using standard quality factors, mean scores from facilities in the different endemicity regions were compared by a Student's t-test. Simple and multiple linear regression analyses were performed to determine the association between facility performance (score) and endemicity (mesoendemic vs. hypoendemic). Facilities in mesoendemic regions scored higher than those in hypoendemic regions on the overall quality of services [difference in mean scores ([Formula: see text]) = 2.52; (95% Confidence Interval (CI) 1.12, 3.91)], site readiness [[Formula: see text] = 2.97; (95% CI 1.30, 4.61)], availability of malaria reference materials [[Formula: see text] = 4.91; (95% CI 2.05, 7.76)], availability of Health Management Information System tools [[Formula: see text] = 5.86; (95% CI 3.80, 7.92)] and patient satisfaction [[Formula: see text] = 6.61; (95% CI 3.75, 9.48)]. Predictors associated with lower facility scores included; being located in a hypoendemic region [β: -2.49; (95% CI -3.83, -1.15)] and urban area [β: -3.84; (95% CI -5.60, -2.08)]. These findings highlight the differences in quality of malaria case management based on endemicity, but there is still a need to target improvement efforts in underperforming facilities, regardless of endemicity. |
Physical activity-friendly policies and community design features in the US, 2014 and 2021
Webber BJ , Whitfield GP , Moore LV , Stowe E , Omura JD , Pejavara A , Galuska DA , Fulton JE . Prev Chronic Dis 2023 20 E72 INTRODUCTION: The 2014 Community-Based Survey of Supports for Healthy Eating and Active Living documented the prevalence of US municipal policy and community design supports for physical activity. The survey was repeated in 2021. Our study examined change in the prevalence of supports from 2014 to 2021, overall and by municipality characteristic. METHODS: Municipalities were sampled independently each survey year. We calculated prevalence in 2014 and 2021 and the prevalence ratio (PR) for 15 supports covering zoning codes, park policies and budgets, design standards, Complete Streets policies, and shared use agreements. We used a Bonferroni-corrected Breslow-Day test to test for interaction by municipality characteristic. RESULTS: In 2014 (2,009 municipalities) compared with 2021 (1,882 municipalities), prevalence increased for several zoning codes: block sizes of walkable distances (PR = 1.46), minimum sidewalk width (PR = 1.19), pedestrian amenities along streets (PR = 1.15), continuous sidewalk coverage (PR = 1.14), and building orientation to pedestrian scale (PR = 1.08). Prevalence also increased for design standards requiring dedicated bicycle infrastructure for roadway expansion projects or street retrofits (PR = 1.19). Prevalence declined for shared use agreements (PR = 0.87). The prevalence gap widened between the most and least populous municipalities for Complete Streets policies (from a gap of 33.6 percentage points [PP] in 2014 to 54.0 PP in 2021) and for zoning codes requiring block sizes that were walkable distances (from 11.8 PP to 41.4 PP). CONCLUSION: To continue progress, more communities could consider adopting physical activity-friendly policies and design features. |
Pandemic-related stressors and mental health among women with a live birth in 2020
Meeker JR , Strid P , Simeone R , D'Angelo DV , Dieke A , von Essen BS , Galang RR , Zapata LB , Ellington S . Arch Womens Ment Health 2023 26 (6) 767-776 The objective of this analysis was to assess the associations between pandemic-related stressors and feeling more anxious/depressed, among women with a live birth. We analyzed data from the Pregnancy Risk Assessment Monitoring System (PRAMS) COVID-19 maternal experiences supplement, implemented in 29 U.S. jurisdictions from October 2020-June 2021, among women with a live birth during April-December 2020. We examined stressors by type (economic, housing, childcare, food insecurity, partner, COVID-19 illness) and score (number of stressor types experienced [none, 1-2, 3-4, or 5-6]). Outcomes were feeling 1) more anxious and 2) more depressed than usual due to the pandemic. We calculated adjusted prevalence ratios estimating associations between stressors and outcomes. Among 12,525 respondents, half reported feeling more anxious and 28% more depressed than usual. The prevalence of stressor types was 50% economic, 41% childcare, 18% partner, 17% food insecurity, 12% housing, and 10% COVID-19 illness. Respondents who experienced partner stressors (anxious aPR: 1.81, 95% CI: 1.73-1.90; depressed aPR: 3.01, 95% CI: 2.78-3.25) and food insecurity (anxious aPR: 1.79, 95% CI: 1.71-1.88; depressed aPR: 2.32, 95% CI: 2.13-2.53) had the largest associations with feeling more anxious and depressed than usual. As stressor scores increased, so did the aPRs for feeling more anxious and more depressed due to the pandemic. COVID-19 stressors, not COVID-19 illness, were found to be significantly associated with feeling more anxious and depressed. Pregnant and postpartum women might benefit from access to supports and services to address pandemic-related stressors/social-determinants and feelings of anxiety and depression. |
Changes in sales of tobacco and nicotine replacement therapy products before and during the COVID-19 pandemic
Sung J , Shrestha SS , Kim Y , Emery S , Wang X . Prev Chronic Dis 2023 20 E71 INTRODUCTION: The COVID-19 pandemic and its associated social distancing policies such as lockdowns and quarantine influenced people's lives and health behaviors. We comprehensively assessed national trends in sales of cigarettes, cigars, e-cigarettes, and over-the-counter nicotine replacement therapy (NRT) products before and during the pandemic, allowing for cross-product comparisons. Stockpiling behavior was also assessed. METHODS: We used US national tobacco and over-the-counter NRT retail store scanner data (excluding internet, specialty/vape store, and prescription sales) collected at 4-week intervals by NielsenIQ from December 2018 to June 2021. We applied an interrupted time-series model to assess differences in tobacco product and NRT unit sales before and during the pandemic. We defined the prepandemic period as December 16, 2018, through April 4, 2020, pandemic as starting on April 5, 2020, through June 26, 2021, and the stockpiling period as one 4-week period before the pandemic started. RESULTS: Four-week cigarette, e-cigarette, and cigar unit sales on average increased by 11.5% (P = .006), 37.1% (P < .001), and 26.1% (P < .001) respectively, while 4-week NRT unit sales decreased on average by 13.1% (P < .001), during the pandemic compared with the prepandemic period. Stockpiling was associated with increases in sales of all tobacco products and NRT products. CONCLUSION: Unit sales of assessed tobacco products increased while NRT unit sales decreased during the COVID-19 pandemic, compared with the prepandemic period. These changes may suggest an increase in the intensity of tobacco product use or stockpiling of tobacco products among people who use tobacco. |
COVID-19 booster dose reminder/recall for adolescents: Findings from a health-care system in Wisconsin
Alonge OD , Hanson KE , Eggebrecht M , Funk P , Christianson B , Williams CL , Belongia EA , McLean HQ . J Adolesc Health 2023 73 (5) 953-956 PURPOSE: This study assessed efficacy of one-time COVID-19 booster reminder/recall for booster eligible adolescents in a health-care system in Wisconsin. METHODS: COVID-19 booster eligible patients aged 12-17 years were randomized 1:1 to receive one reminder/recall message from the health-care system using the parent's preferred communication method (intervention) or no reminder/recall (usual care) in May 2022. RESULTS: Reminder/recall was sent to 2,146/4,296 (50%) adolescent patients. During the 90-day evaluation period following randomization, booster dose receipt was 2.0 percentage points (CI: 0.3%-3.7%) higher in the intervention (10.0%) versus usual care groups (8.0%). Among patients with ≥1 preventive visit during the evaluation period, uptake was 7.5 percentage points higher in the intervention (16.4%) versus usual care groups (8.9%). DISCUSSION: A single COVID-19 booster dose reminder/recall resulted in a small but statistically significant increase in booster dose receipt, though uptake overall was low. Additional strategies are needed to increase uptake. |
CDC extended BMI-for-age percentiles versus percent of the 95th percentile
Ogden CL , Freedman DS , Hales CM . Pediatrics 2023 152 (3) In December 2022, the Centers for Disease Control and Prevention (CDC) released Extended BMI-for-age growth charts1,2 for children and adolescents with high BMI values. These charts extend to a BMI of 60 and add 4 growth curves (98th, 99th, 99.9th, and 99.99th percentiles). Obesity among children and adolescents is defined as BMI ≥95th percentile of BMI-for-age and severe obesity as BMI ≥120% of the 95th percentile or ≥35.3 The recent American Academy of Pediatrics guideline for the treatment of obesity recommends using percentages of the 95th percentile of BMI-for-age to indicate different levels of severe obesity.4 This analysis compares CDC extended BMI-for-age percentiles with 120% and 140% of the 95th percentile and illustrates the differences between the prevalence of US children and adolescents 2 to 19 years of age with a BMI ≥ extended 98th percentile using the newly defined curve and those ≥120% of the 95th percentile using 2017 to March 2020 National Health and Nutritional Examination (NHANES) data. |
First record of Babesia and Theileria parasites in ticks from Kassena-Nankana, Ghana
Addo SO , Bentil RE , Baako BOA , Addae CA , Behene E , Asoala V , Mate S , Oduro D , Dunford JC , Larbi JA , Baidoo PK , Wilson MD , Diclaro JW 2nd , Dadzie SK . Med Vet Entomol 2023 37 (4) 878-882 Ticks are efficient vectors for transmitting pathogens that negatively affect livestock production and pose a risk to public health. In this study, Babesia and Theileria species were identified in ticks collected from cattle, sheep and goats from the Kassena-Nankana Districts of Ghana between February and December 2020. A total of 1550 ticks were collected, morphologically identified, pooled and screened for pathogens using primers that amplify a 560 bp fragment of the ssrRNA gene and Sanger sequencing. Amblyomma variegatum (62.98%) was the predominant tick species. From the 491 tick pools screened, 12/15 (2.44%) positive pools were successfully sequenced. The pathogen DNA identified were Theileria ovis in eight (15.38%) pools of Rhipicephalus evertsi evertsi, Theileria velifera in two (0.78%) pools of A. variegatum and Babesia occultans and Babesia sp. Xinjiang in one (1.72%) pool each of Hyalomma truncatum. It was further observed that T. ovis occurred in ticks collected from only sheep (p < 0.001) which were females (p = 0.023) and < =1 year old (p = 0.040). This study reports the first identification of these pathogens in ticks within Kassena-Nankana. With the constant trade of livestock, there is a need for effective tick control measures to prevent infection spread. |
Comparison of acarological risk metrics derived from active and passive surveillance and their concordance with tick-borne disease incidence
Holcomb KM , Khalil N , Cozens DW , Cantoni JL , Brackney DE , Linske MA , Williams SC , Molaei G , Eisen RJ . Ticks Tick Borne Dis 2023 14 (6) 102243 Tick-borne diseases continue to threaten human health across the United States. Both active and passive tick surveillance can complement human case surveillance, providing spatio-temporal information on when and where humans are at risk for encounters with ticks and tick-borne pathogens. However, little work has been done to assess the concordance of the acarological risk metrics from each surveillance method. We used data on Ixodes scapularis and its associated human pathogens from Connecticut (2019-2021) collected through active collections (drag sampling) or passive submissions from the public to compare county estimates of tick and pathogen presence, infection prevalence, and tick abundance by life stage. Between the surveillance strategies, we found complete agreement in estimates of tick and pathogen presence, high concordance in infection prevalence estimates for Anaplasma phagocytophilum, Borrelia burgdorferi sensu stricto, and Babesia microti, but no consistent relationships between actively and passively derived estimates of tick abundance or abundance of infected ticks by life stage. We also compared nymphal metrics (i.e., pathogen prevalence in nymphs, nymphal abundance, and abundance of infected nymphs) with reported incidence of Lyme disease, anaplasmosis, and babesiosis, but did not find any consistent relationships with any of these metrics. The small spatial and temporal scale for which we had consistently collected active and passive data limited our ability to find significant relationships. Findings are likely to differ if examined across a broader spatial or temporal coverage with greater variation in acarological and epidemiological outcomes. Our results indicate similar outcomes between some actively and passively derived tick surveillance metrics (tick and pathogen presence, pathogen prevalence), but comparisons were variable for abundance estimates. |
