Phase level assessment of ergonomic intervention effectiveness in reducing knee musculoskeletal disorder risks during residential roof shingle installation
Zerin N , Breloff SP , Dai F , Carey RE , Warren CM , Moore K , Hawke A , Wu JZ . Am J Ind Med 2025 BACKGROUND: This study aimed to assess how knee savers (KSs) and knee pads (KPs) alleviate risks of knee musculoskeletal disorders (MSDs) among roofers during various phases of shingle installation. These phases encompass (1) reaching for shingles, (2) placing shingles, (3) grabbing a nail gun, (4) moving to the first nailing position, (5) nailing shingles, (6) replacing the nail gun, and (7) returning to an upright position. METHODS: In a laboratory setting, nine male participants simulated the shingle installation task on a slope-adjustable roof platform (0°, 15°, and 30° slopes) under four intervention conditions: no intervention (NO); with KPs only (KP); with KSs only (KS); and with both KPs and KSs (BO). Knee flexion, abduction, adduction, and internal/external rotations were measured to assess intervention impact through statistical analysis. RESULTS: Phase 5 (nailing shingles), one of the riskiest phases, saw reduced knee rotations, with BO and KP interventions being the most effective. Phase 6 (replacing the nail gun) exhibited notable reductions in all knee rotations, primarily due to BO intervention. Significant improvements in certain knee angles for other phases were noted, particularly with BO intervention. CONCLUSIONS: BO and KP can lower knee strain by minimizing extreme knee postures and thereby reducing the risk of MSDs during the installation of shingles, especially at critical periods and on steeper slopes. This study highlights the importance of applying focused ergonomic techniques in the roofing sector to improve workers' musculoskeletal health. |

J Acquir Immune Defic Syndr 2025 INTRODUCTION: We assessed the risk of adverse pregnancy and birth outcomes and birth defects among women living with HIV (WLHIV) on antiretroviral therapy (ART) and HIV-negative women. METHODS: We analyzed data on live births, stillbirths, and spontaneous abortions during 2015-2021 from a hospital-based birth defects surveillance system in Kampala, Uganda. ART regimens were recorded from hospital records and maternal self-reports. Using a log-binomial regression model, we compared the prevalence of 16 major external birth defects and other adverse birth outcomes among WLHIV on ART and HIV-negative women. RESULTS: A total of 203,092 births were included from 196,373 women of which 15,020 (7.6%) were WLHIV on ART. During pregnancy, 15,566 infants were primarily exposed to non-nucleoside reverse transcriptase inhibitor (NNRTI)-based ART (n=13,614; 87.5%). After adjusting for maternal age, parity, and number of antenatal care (ANC) visits, WLHIV on NNRTI were more likely than HIV-negative women to deliver preterm (adjusted prevalence ratio [aPR]=1.27, 95% confidence interval [CI]: 1.21,1.32), post-term (aPR=1.23, 95% CI: 1.16,1.32), or small for gestational age infants (aPR=1.35, 95% CI: 1.30,1.40). Spina bifida was more prevalent among infants born to WLHIV on ART periconceptionally compared to HIV-negative women (aPR=2.45, 95% CI 1.27,4.33). The prevalence of the other selected birth defects were similar between infants from WLHIV on ART and HIV-negative women. CONCLUSION: In Uganda, WLHIV on ART were more likely than HIV-negative women to experience selected adverse birth outcomes. Further surveillance of maternal ART exposure, including by drug class and ART regimen, is needed to monitor and prevent adverse birth outcomes in WLHIV. |
Observed prevalence of congenital situs inversus in the United States before and during the SARS-CoV-2 pandemic, 2017-2022
Cragan JD , Cho SJ , Forestieri N , Hort M , Nestoridi E , Moore CA , Stallings E , Gray EB , Reefhuis J . Birth Defects Res 2024 116 (12) e2424 BACKGROUND: Reports from China describe an increase in the frequency of fetal situs inversus in 2023 after the country's "zero-Covid" policy was lifted, suggesting an association with maternal SARS-CoV-2 infection. However, a report of birth defects surveillance data from Scandinavia observed no sustained increase during the SARS-CoV-2 pandemic (2020-2022 vs. 2018-2019). We examined birth defects surveillance data to assess any increase in situs inversus in the U.S. during the SARS-CoV-2 pandemic. METHODS: We combined data from four population-based birth defects programs in Massachusetts, Minnesota, North Carolina, and Atlanta, Georgia, to compare the prevalence of situs inversus among infants and fetuses delivered before (2017-2019) and during (2021-2022) the SARS-CoV-2 pandemic. We defined situs inversus as mirror-image transposition of the heart and/or other organs, or primary ciliary dyskinesis with situs inversus, excluding isolated dextrocardia. The programs varied in the pregnancy outcomes included (live births ± non-live births); all included both prenatal and postnatal diagnoses. RESULTS: We identified 294 infants and fetuses with situs inversus (6.8% non-live births). We estimated the combined prevalence per 10,000 live births as 1.72 during the pandemic versus 1.71 before the pandemic (OR = 1.005; 95% CI: 0.778-1.297). The estimated annual prevalence ranged from 1.41 in 2017 to 2.21 in 2019 with no significant trend across the study period (p = 0.39). CONCLUSIONS: We did not observe an increase in situs inversus during the SARS-CoV-2 pandemic. Because information about SARS-CoV-2 infection among individual pregnancies was not available from all programs, we could not assess a specific association with maternal infection. |
Risk of transmission of vaccine-strain rotavirus in a neonatal intensive care unit that routinely vaccinates
Zalot MA , Cortese MM , O'Callaghan KP , Casey-Moore MC , L'Etoile N , Smart SL , Honeywood MJ , Mijatovic-Rustempasic S , Tate JE , Davis A , Wittmeyer N , McGann C , Sadaf S , Wilson K , Bowen MD , Gautam R , Parashar UD , Coffin SE , Gibbs KA . Pediatrics 2024 ![]() ![]() BACKGROUND AND OBJECTIVES: Many neonatal intensive care units (NICUs) do not give rotavirus vaccines to inpatients due to a theoretical risk of horizontal transmission of vaccine strains. We aimed to determine incidence and clinical significance of vaccine-strain transmission to unvaccinated infants in a NICU that routinely administers pentavalent rotavirus vaccine (RV5). METHODS: This prospective cohort study included all patients admitted to a 100-bed NICU for 1 year. Stool specimens were collected weekly; real-time quantitative reverse-transcription polymerase chain reaction was used to detect any RV5 strain. Incidence of transmission to unvaccinated infants was calculated assuming each unvaccinated patient's stool contributed 1 patient-day at risk for transmission. Investigations and geospatial analyses were conducted for suspected transmission events. RESULTS: Of 1238 infants admitted, 560 (45%) were premature and 322 (26%) had gastrointestinal pathology. During observation, 226 RV5 doses were administered. Overall, 3448 stool samples were tested, including 2252 from 686 unvaccinated patients. Most (681, 99.3%) unvaccinated patients never tested positive for RV5 strain. Five (<1%) tested RV5 strain positive. The estimated rate of transmission to unvaccinated infants was 5/2252 stools or 2.2/1000 patient-days at risk (95% CI: 0.7-5.2). No gastroenteritis symptoms were identified in transmission cases within 7 days of collection of RV5-positive stool. Of 126 patients for whom the RV5 series was initiated before the discharge date, 55% would have become age-ineligible to start the series if vaccination was allowed only at discharge. CONCLUSIONS: Transmission of RV5 strain was infrequent and without clinical consequences. Benefits of allowing vaccine-induced protection against rotavirus disease in infants through in-NICU RV5 vaccination appear to have outweighed risks from vaccine-strain transmission. |

El Kalach RR , Jones-Jack NH , Grabenstein JD , Elam M , Olorukooba A , deMartino AK , Vazquez M , Stokley S , Meyer SA , Wang TW , Himsel A , Medernach C , Jenkins K , Marovich S , Bradley MD , Manns BJ , Romerhausen D , Moore LB . J Am Pharm Assoc (2003) 2024 102305 BACKGROUND: The Federal Retail Pharmacy Program (FRPP) integrated pharmacies as partners in the national effort to maximize vaccination during the COVID-19 public health emergency. OBJECTIVES: The objective of this study was to quantify the contribution of pharmacies participating in FRPP to COVID-19 vaccination efforts during December 2020-September 2023 across sociodemographic groups in the United States. METHODS: Data on COVID-19 vaccine doses administered reported to CDC by FRPP and jurisdictional immunization information systems (IIS) of all 50 states, the District of Columbia, and U.S. territories were analyzed to estimate FRPP contributions. RESULTS: Approximately 314.9 million COVID-19 vaccine doses were administered by FRPP throughout this period, constituting 48.9% of all COVID-19 vaccine doses administered. FRPP contributions to COVID-19 vaccination ranged from 12.9% to 56.8% for persons aged 6 months-4 years and 12-17 years, respectively. FRPP made the highest contribution to administering COVID-19 doses to Non-Hispanic Asian (48.7%) and Hispanic/Latino (49.8%) persons. The proportion of COVID-19 doses given by FRPP pharmacies was found to be higher in urban areas (57%) compared with rural areas (45%). CONCLUSION: FRPP administered a substantial proportion of COVID-19 vaccine doses in the United States and provided vaccine access for persons across a wide range of groups. Pharmacies can complement vaccination efforts during public health emergency situations and in routine vaccination programs. |
Endurance exercise training alters lipidomic profiles of plasma and eight tissues in rats: a MoTrPAC study
Ortlund E , Hou Z , Chen CY , Gaul D , Zhang T , Moore S , Liu X , Ivanova A , Maner-Smith K , Newgard C , Bodine S , Savage E , Bennett A , Fernandez F . Res Sq 2024 Endurance exercise training (ExT) induces metabolic, structural, and functional adaptations via lipidomic modifications, yet the systematic elucidation of lipidome alterations in response to ExT remains incomplete. As a part of the Molecular Transducers of Physical Activity Consortium (MoTrPAC), we leveraged non-targeted and targeted lipidomics for the systematic discovery of lipid alterations in the brown adipose tissue, heart, hippocampus, kidney, liver, lung, skeletal muscle gastrocnemius, subcutaneous white adipose tissue, and plasma in response to 1, 2, 4 or 8 weeks of ExT in 6-month-old male and female Fischer-344 rats. This study demonstrates that these tissues, each with distinct lipidomic features, underwent dynamic, sexually dimorphic lipid remodeling. Exercise trained animals showed reduced whole-body adiposity and improved cardiorespiratory fitness, along with enhanced utilization of lipid stores and dynamic triacylglycerol remodeling compared to sedentary controls in all tissues except hippocampus. They also showed modifications in phospholipids, lysophospholipids, oxylipins, and ceramides in several tissues. Coordinated changes across tissues reflect systemic tissue communication, with liver-plasma-heart connection potentially playing a key role in systemic lipid metabolism during ExT. These data will improve our understanding of lipid-associated biological processes underlying the health-promoting benefits of ExT. |
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. |

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. |

Clin Microbiol Infect 2024 ![]() OBJECTIVES: After respiratory syncytial virus (RSV), human metapneumovirus (hMPV) was the second-ranked pathogen attributed to severe pneumonia in the PERCH study. We sought to characterize hMPV-positive cases in high burden settings, which have limited data, by comparing to RSV-positive and other cases. METHODS: Children aged 1-59 months hospitalized with suspected severe pneumonia and age/season-matched community controls in seven African and Asian countries had nasopharyngeal/oropharyngeal swabs tested by multiplex PCR for 32 respiratory pathogens, among other clinical and lab assessments at admission. Odds ratios adjusted for age and site (aOR) were calculated using logistic regression. Etiologic probability was estimated using Bayesian nested partial latent class analysis. Latent class analysis identified syndromic constellations of clinical characteristics. RESULTS: HMPV was detected more frequently among cases (267/3887, 6.9%) than controls (115/4976, 2.3%), among cases with pneumonia chest X-ray findings (8.5%) than without (5.5%), and among controls with respiratory tract illness (3.8%) than without (1.8%; all p≤0.001). HMPV-positive cases were negatively associated with the detection of other viruses (aOR=0.18), especially RSV (aOR=0.11; all p<0.0001), and positively associated with the detection of bacteria (aORs 1.77, p=0.03). No single clinical syndrome distinguished hMPV-positive from other cases. Among hMPV-positive cases, 65.2% were aged <1 year and 27.5% had pneumonia danger signs; positive predictive value was 74.5%; mortality was 3.9%, similar to RSV-positive (2.4%) and lower than other cases (9.6%). CONCLUSIONS: HMPV-associated severe pediatric pneumonia in high burden settings was predominantly in young infants and clinically indistinguishable from RSV. HMPV-positives had low case fatality, similar to that in RSV-positives. |
Managing recruitment and data collection: Online focus groups best practices and strategies to address scammers
Lee M , Augustine D , Moore M . New Trend Qual Res 2024 20 (4) Common methods to collect data include quantitative, qualitative, and mixed method approaches. Although it is common to complete data collection in-person, the onset of COVID-19 has resulted in the increased use of online modalities. Qualitative research is commonly gathered through individual or focus group interviews. However, best practices outlining strategies when conducting online focus groups and approaches to address issues specific to online research (i.e., scammers) are limited. Due to the growing use of data collection through such means, it is imperative to draw out specific strategies that could regulate data quality and reduce the chances of scamming. The current article addresses this practical gap by providing a synthesis of the available literature on online focus groups that document best practices and suggestions to deal with scammers which is currently missing from the literature. The goal was to provide initial suggestions to improve data quality of online focus groups by examining the available literature that outlines best practices, addresses the issues of scammers, and to provide a concise and comprehensive overview of identified literature The article is organized beginning with a review of the literature. The research is then synthesized including an outline of best practices and strategies to address scammers when engaging in online focus groups. The article closes with a discussion of the significance of the review, limitations, and article summary. Scammers are prevalent in online spaces. Although this article provides a preliminary outline of suggestions from the literature, more research is necessary that provides specific examples of how challenges have been addressed and the impact of including the recommended strategies on the research process and outcomes. © 2024, Ludomedia EN.

Increased stillbirth rates and exposure to environmental risk factors for stillbirth in counties with higher social vulnerability: United States, 2015-2018
Moore J , Evans S , Rose CE , Shin M , Carroll Y , Duke CW , Cohen CR , Broussard CS . Matern Child Health J 2024 INTRODUCTION: Exposure to unfavorable environmental conditions during pregnancy, such as extreme heat and air pollution, has been linked to increased risk of stillbirth, defined as fetal mortality at or after 20 weeks' gestation, however no studies have examined its association with social vulnerability. We examined associations between county-level stillbirth rates, environmental risk factors for stillbirth, and social vulnerability in the United States. METHODS: This ecologic study linked county-level data from three nationwide datasets on stillbirths (National Vital Statistics System), environmental conditions (North American Land Data Assimilation System and Environmental Protection Agency), and social vulnerability (Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry Social Vulnerability Index). Poisson and negative binomial models were fit to the variables and produced rate ratios to estimate associations among stillbirth rates, environmental risk factors, and social vulnerability. RESULTS: Social vulnerability was positively associated withn stillbirth rates, annual average number of extreme heat days, and ambient concentration of particulate matter ≤ 2.5 μm in diameter (PM2.5). The average number of days that ozone and PM2.5 each exceeded regulatory standards were not associated with stillbirth rates or social vulnerability. A positive association between average annual PM2.5 concentration and stillbirth rates was detected; no other significant associations between environmental risk factors and stillbirth rates were observed. DISCUSSION: We found evidence of associations between social vulnerability and stillbirth rates, and between social vulnerability and environmental risk factors for stillbirth at the county level. Further research could inform understanding of how social vulnerability impacts the relationship between environmental exposures and stillbirth risk. |
Mental health and suicide risk among high school students and protective factors - Youth Risk Behavior Survey, United States, 2023
Verlenden JV , Fodeman A , Wilkins N , Jones SE , Moore S , Cornett K , Sims V , Saelee R , Brener ND . MMWR Suppl 2024 73 (4) 79-86 Adolescent mental health and suicide risk remain substantial public health concerns. High pre-COVID rates of poor mental health and suicide-related behaviors have continued to rise, highlighting the need to identify factors that might foster positive mental health outcomes and reduce suicide-related behaviors at population levels. Using CDC's 2023 Youth Risk Behavior Survey, CDC analyzed the prevalence of mental health and suicide risk indicators and their associations with individual-, family-, and school- or community-level protective factors. Prevalence estimates were calculated for each of the mental health and suicide risk indicators by demographic characteristic. Prevalence ratios adjusted for sex, sexual identity, grade, and race and ethnicity were calculated to examine the association between protective factors and mental health and suicide risk indicators. Overall, 39.7% of students experienced persistent feelings of sadness and hopelessness, 28.5% experienced poor mental health, 20.4% seriously considered attempting suicide, and 9.5% had attempted suicide. Mental health and suicide risk indicators differed by sex, sexual identity, grade, and race and ethnicity. All protective factors were associated with lower prevalence of one or more risk indicators. Findings from this report can serve as a foundation for the advancement of research on protective factors and for the development and implementation of programs, practices, and policies that protect and promote mental health and emotional well-being among youth. |
Frequent social media use and experiences with bullying victimization, persistent feelings of sadness or hopelessness, and suicide risk among high school students - Youth Risk Behavior Survey, United States, 2023
Young E , McCain JL , Mercado MC , Ballesteros MF , Moore S , Licitis L , Stinson J , Everett Jones S , Wilkins NJ . MMWR Suppl 2024 73 (4) 23-30 Social media has become a pervasive presence in everyday life, including among youths. In 2023, for the first time, CDC's nationally representative Youth Risk Behavior Survey included an item assessing U.S. high school students' frequency of social media use. Data from this survey were used to estimate the prevalence of frequent social media use (i.e., used social media at least several times a day) among high school students and associations between frequent social media use and experiences with bullying victimization, persistent feelings of sadness or hopelessness, and suicide risk. All prevalence estimates and measures of association used Taylor series linearization. Prevalence ratios were calculated using logistic regression with predicted marginals. Overall, 77.0% of students reported frequent social media use, with observed differences by sex, sexual identity, and racial and ethnic identity. Frequent social media use was associated with a higher prevalence of bullying victimization at school and electronically, persistent feelings of sadness or hopelessness, and some suicide risk among students (considering attempting suicide and having made a suicide plan), both overall and in stratified models. This analysis characterizes the potential harms of frequent social media use for adolescent health among a nationally representative sample of U.S. high school students. Findings might support multisectoral efforts to create safer digital environments for youths, including decision-making about social media policies, practices, and protections. |

MMWR Morb Mortal Wkly Rep 2024 73 (37) 804-809 ![]() ![]() As part of the response to the highly pathogenic avian influenza A(H5N1) virus outbreak in U.S. cattle and poultry and the associated human cases, CDC and partners are monitoring influenza A virus levels and detection of the H5 subtype in wastewater. Among 48 states and the District of Columbia that performed influenza A testing of wastewater during May 12-July 13, 2024, a weekly average of 309 sites in 38 states had sufficient data for analysis, and 11 sites in four states reported high levels of influenza A virus. H5 subtype testing was conducted at 203 sites in 41 states, with H5 detections at 24 sites in nine states. For each detection or high level, CDC and state and local health departments evaluated data from other influenza surveillance systems and partnered with wastewater utilities and agriculture departments to investigate potential sources. Among the four states with high influenza A virus levels detected in wastewater, three states had corresponding evidence of human influenza activity from other influenza surveillance systems. Among the 24 sites with H5 detections, 15 identified animal sources within the sewershed or adjacent county, including eight milk-processing inputs. Data from these early investigations can help health officials optimize the use of wastewater surveillance during the upcoming respiratory illness season. |
External quality assessment-based tumor marker harmonization simulation; insights in achievable harmonization for CA 15-3 and CEA
Van Rossum HH , Holdenrieder S , Yun YM , Patel D , Thelen M , Song J , Unsworth N , Partridge K , Moore M , Cui W , Ramanathan L , Meng QH , Ballieux Bepb , Sturgeon C , Vesper H . Clin Chem Lab Med 2024 OBJECTIVES: CA 15-3 and CEA are tumor markers used in routine clinical care for breast cancer and colorectal cancer, among others. Current measurement procedures (MP) for these tumor markers are considered to be insufficiently harmonized. This study investigated the achievable harmonization for CA 15-3 and CEA by using an in silico simulation of external quality assessment (EQA) data from multiple EQA programs using patient-pool based samples. METHODS: CA 15-3 and CEA data from SKML (2021), UK NEQAS (2020-2021) and KEQAS (2020-2021) were used. A harmonization protocol was defined in which MPs that were considered equivalent were used to value assign EQA samples, and recalibration was only required if the MP had a bias of >5 % with value assigned EQA. Harmonization status was assessed by determining the mean level of agreement and residual variation by CV (%). RESULTS: Only MPs from Abbott, Beckman, Roche and Siemens were available in all EQA programs. For CA 15-3, recalibration was proposed for Beckman MP only and for CEA, recalibration was proposed for Siemens MP only. When the harmonization procedures were applied, for CA 15-3 the pre-harmonization mean bias range per MP was reduced from -29.28 to 9.86 %, into -0.09-0.12 % after harmonization. For CEA, the mean bias range per MP was reduced from -23.78 to 2.00 % pre-harmonization to -3.13-1.42 % post-harmonization. CONCLUSIONS: The present study suggests that a significant improvement in the harmonization status of CA 15-3 and CEA may be achieved by recalibration of a limited number of MPs. |
"It spreads like wildfire": mothers' gatherings for vaccine acceptance
de Acosta D , Moore T , Alam F , Hoffman SJ , Keaveney M , Mann E , Dawson-Hahn E . Front Public Health 2024 12 1198108 This case study describes the design, implementation, and evaluation of an initiative to increase COVID-19 vaccine confidence and uptake among refugee and immigrant women in Clarkston, Georgia. Applying the principles and practices of human-centered design, Mothers x Mothers was co-created by Refugee Women's Network and IDEO.org as a series of gatherings for refugee and immigrant mothers to discuss health issues, beginning with the COVID-19 vaccine. The gatherings included both vaccinated and unvaccinated mothers and used a peer support model, with facilitation focused on creating a trusting environment and supporting mothers to make their own health decisions. The facilitators for Mothers x Mothers gatherings were community health workers (CHWs) recruited and trained by Refugee Women's Network. Notably, these CHWs were active in every phase of the initiative, from design to implementation to evaluation, and the CHWs' professional development was specifically included among the initiative's goals. These elements and others contributed to an effective public health intervention for community members who, for a variety of reasons, did not get sufficient or appropriate COVID-19 vaccine information through other channels. Over the course of 8 Mothers x Mothers gatherings with 7 distinct linguistic/ethnic groups, 75% of the unvaccinated participants decided to get the COVID-19 vaccine and secured a vaccine referral. |
CDC-funded HIV testing services outcomes in Ending the HIV Epidemic in the U.S. (EHE) and non-EHE jurisdictions, 2021
Patel D , Mulatu MS , Wang G , May AC , Moore A , Rao S . J Infect Dis 2024 BACKGROUND: Ending the HIV Epidemic in the U.S. (EHE) aims to end the HIV epidemic by focusing on 57 jurisdictions most impacted by HIV. METHODS: Using 2021 data from the National HIV Prevention Program Monitoring and Evaluation system, we calculated distributions of CDC-funded HIV tests and HIV testing services outcomes in EHE and non-EHE jurisdictions. We conducted chi-square tests and robust Poisson regression to compare differences in outcomes. RESULTS: Of the 1,753,873 tests conducted, a greater proportion were conducted in EHE (65.7%) versus non-EHE (34.3%) jurisdictions (p<0.001). Greater number of persons newly diagnosed were identified in EHE (n=5,861) versus non-EHE (n=2,329) jurisdictions; newly diagnosed positivity was higher in EHE (0.5%) versus non-EHE (0.4%; PR=1.31, 95% CI: 1.25-1.38) jurisdictions. Among persons newly diagnosed, there were no differences in proportion of linkage to care within 30 days in EHE jurisdictions (77.9%) versus non-EHE jurisdictions (77.1%; PR=1.01, 95% CI: 0.95-1.07). Proportion of persons newly diagnosed interviewed for partner services was lower in EHE (69.0%) versus non-EHE (84.8%; PR=0.81, 95% CI: 0.76-0.87) jurisdictions. CONCLUSION: CDC-funded HIV testing services in EHE jurisdictions conducted more HIV testing and diagnosed more persons. Jurisdictions can further expand HIV testing and related services to continue striving toward EHE goals. |
SARS-CoV-2 correlates of protection from infection against variants of concern
Sun K , Bhiman JN , Tempia S , Kleynhans J , Madzorera VS , Mkhize Q , Kaldine H , McMorrow ML , Wolter N , Moyes J , Carrim M , Martinson NA , Kahn K , Lebina L , du Toit JD , Mkhencele T , von Gottberg A , Viboud C , Moore PL , Cohen C . Nat Med 2024 ![]() Serum neutralizing antibodies (nAbs) induced by vaccination have been linked to protection against symptomatic and severe coronavirus disease 2019. However, much less is known about the efficacy of nAbs in preventing the acquisition of infection, especially in the context of natural immunity and against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immune-escape variants. Here we conducted mediation analysis to assess serum nAbs induced by prior SARS-CoV-2 infections as potential correlates of protection against Delta and Omicron infections, in rural and urban household cohorts in South Africa. We find that, in the Delta wave, D614G nAbs mediate 37% (95% confidence interval: 34-40%) of the total protection against infection conferred by prior exposure to SARS-CoV-2, and that protection decreases with waning immunity. In contrast, Omicron BA.1 nAbs mediate 11% (95% confidence interval: 9-12%) of the total protection against Omicron BA.1 or BA.2 infections, due to Omicron's neutralization escape. These findings underscore that correlates of protection mediated through nAbs are variant specific, and that boosting of nAbs against circulating variants might restore or confer immune protection lost due to nAb waning and/or immune escape. However, the majority of immune protection against SARS-CoV-2 conferred by natural infection cannot be fully explained by serum nAbs alone. Measuring these and other immune markers including T cell responses, both in the serum and in other compartments such as the nasal mucosa, may be required to comprehensively understand and predict immune protection against SARS-CoV-2. |

Birth Defects Res 2024 116 (7) e2384 ![]() BACKGROUND: Primary congenital glaucoma (PCG) affects approximately 1 in 10,000 live born infants in the United States (U.S.). PCG has a autosomal recessive inheritance pattern, and variable expressivity and reduced penetrance have been reported. Likely causal variants in the most commonly mutated gene, CYP1B1, are less prevalent in the U.S., suggesting that alternative genes may contribute to the condition. This study utilized exome sequencing to investigate the genetic architecture of PCG in the U.S. and to identify novel genes and variants. METHODS: We studied 37 family trios where infants had PCG and were part of the National Birth Defects Prevention Study (births 1997-2011), a U.S. multicenter study of birth defects. Samples underwent exome sequencing and sequence reads were aligned to the human reference sample (NCBI build 37/hg19). Variant filtration was conducted under de novo and Mendelian inheritance models using GEMINI. RESULTS: Among candidate variants, CYP1B1 was most represented (five trios, 13.5%). Twelve probands (32%) had potentially pathogenic variants in other genes not previously linked to PCG but important in eye development and/or to underlie Mendelian conditions with potential phenotypic overlap (e.g., CRYBB2, RXRA, GLI2). CONCLUSION: Variation in the genes identified in this population-based study may help to further explain the genetics of PCG. |
Large-scale laboratory investigation of pillar-support interaction
Chaurasia A , Walton G , Sinha S , Batchler TJ , Moore K , Vlachopoulos N , Forbes B . J Rock Mech Geotech Eng 2024 [Epub ahead of print] Underground mine pillars provide natural stability to the mine area, allowing safe operations for workers and machinery. Extensive prior research has been conducted to understand pillar failure mechanics and design safe pillar layouts. However, limited studies (mostly based on empirical field observation and small-scale laboratory tests) have considered pillar-support interactions under monotonic loading conditions for the design of pillar-support systems. This study used a series of large-scale laboratory compression tests on porous limestone blocks to analyze rock and support behavior at a sufficiently large scale (specimens with edge length of 0.5m) for incorporation of actual support elements, with consideration of different w/h ratios. Both unsupported and supported (grouted rebar rockbolt and wire mesh) tests were conducted, and the surface deformations of the specimens were monitored using three-dimensional (3D) digital image correlation (DIC). Rockbolts instrumented with distributed fiber optic strain sensors were used to study rockbolt strain distribution, load mobilization, and localized deformation at different w/h ratios. Both axial and bending strains were observed in the rockbolts, which became more prominent in the post-peak region of the stress-strain curve. |

Lancet Infect Dis 2024 Nipah virus causes highly lethal disease, with case-fatality rates ranging from 40% to 100% in recognised outbreaks. No treatments or licensed vaccines are currently available for the prevention and control of Nipah virus infection. In 2019, WHO published an advanced draft of a research and development roadmap for accelerating development of medical countermeasures, including diagnostics, therapeutics, and vaccines, to enable effective and timely emergency response to Nipah virus outbreaks. This Personal View provides an update to the WHO roadmap by defining current research priorities for development of Nipah virus medical countermeasures, based primarily on literature published in the last 5 years and consensus opinion of 15 subject matter experts with broad experience in development of medical countermeasures for Nipah virus or experience in the epidemiology, ecology, or public health control of outbreaks of Nipah virus. The research priorities are organised into four main sections: cross-cutting issues (for those that apply to more than one category of medical countermeasures), diagnostics, therapeutics, and vaccines. The strategic goals and milestones identified in each section focus on key achievements that are needed over the next 6 years to ensure that the necessary tools are available for rapid response to future outbreaks of Nipah virus or related henipaviruses. |

Pediatric tuberculosis: A review of evidence-based best practices for clinicians and health care providers
Moore BK , Graham SM , Nandakumar S , Doyle J , Maloney SA . Pathogens 2024 13 (6) Advances in pediatric TB care are promising, the result of decades of advocacy, operational and clinical trials research, and political will by national and local TB programs in high-burden countries. However, implementation challenges remain in linking policy to practice and scaling up innovations for prevention, diagnosis, and treatment of TB in children, especially in resource-limited settings. There is both need and opportunity to strengthen clinician confidence in making a TB diagnosis and managing the various manifestations of TB in children, which can facilitate the translation of evidence to action and expand access to new tools and strategies to address TB in this population. This review aims to summarize existing guidance and best practices for clinicians and health care providers in low-resource, TB-endemic settings and identify resources with more detailed and actionable information for decision-making along the clinical cascade to prevent, find, and cure TB in children. |

Kancherla V , Rhoads A , Conway KM , Suhl J , Langlois PH , Hoyt AT , Shaw GM , Evans SP , Moore CA , Luben TJ , Michalski A , Feldkamp ML , Romitti PA . Birth Defects Res 2024 116 (6) e2370 BACKGROUND: Associations between maternal periconceptional exposure to disinfection by-products (DBPs) in drinking water and neural tube defects (NTDs) in offspring are inconclusive, limited in part by exposure misclassification. METHODS: Maternal interview reports of drinking water sources and consumption from the National Birth Defects Prevention Study were linked with DBP concentrations in public water system monitoring data for case children with an NTD and control children delivered during 2000-2005. DBPs analyzed were total trihalomethanes, the five most common haloacetic acids combined, and individual species. Associations were estimated for all NTDs combined and selected subtypes (spina bifida, anencephaly) with maternal periconceptional exposure to DBPs in public water systems and with average daily periconceptional ingestion of DBPs accounting for individual-level consumption and filtration information. Mixed effects logistic regression models with maternal race/ethnicity and educational attainment at delivery as fixed effects and study site as a random intercept were applied. RESULTS: Overall, 111 case and 649 control children were eligible for analyses. Adjusted odds ratios for maternal exposure to DBPs in public water systems ranged from 0.8-1.5 for all NTDs combined, 0.6-2.0 for spina bifida, and 0.7-1.9 for anencephaly; respective ranges for average daily maternal ingestion of DBPs were 0.7-1.1, 0.5-1.5, and 0.6-1.8. Several positive estimates (≥1.2) were observed, but all confidence intervals included the null. CONCLUSIONS: Using community- and individual-level data from a large, US, population-based, case-control study, we observed statistically nonsignificant associations between maternal periconceptional exposure to total and individual DBP species in drinking water and NTDs and subtypes. |

J Infect Dis 2024 In IMPAACT 2010/VESTED, pregnant women were randomized to initiate dolutegravir (DTG)+emtricitabine (FTC)/tenofovir alafenamide (TAF), DTG+FTC/tenofovir disoproxil fumarate (TDF), or efavirenz (EFV)/FTC/TDF. We assessed red blood cell folate concentrations (RBC-folate) at maternal study entry and delivery, and infant birth. RBC-folate outcomes were: 1) maternal change entry to delivery (trajectory), 2) infant, 3) ratio of infant-to-maternal delivery. Generalized estimating equation models for each log(folate) outcome were fit to estimate adjusted geometric mean ratio (Adj-GMR)/GMR trajectories (Adj-GMRT) of each arm comparison in 340 mothers and 310 infants. Overall, 90% of mothers received folic acid supplements and 78% lived in Africa. At entry, median maternal age was 25 years, gestational age was 22 weeks, CD4 count was 482 cells/mm3 and log10HIV RNA was 3 copies/mL. Entry RBC-folate was similar across arms. Adj-GMRT of maternal folate was 3% higher in the DTG+FTC/TAF versus EFV/FTC/TDF arm (1.03, 95%CI 1.00, 1.06). The DTG+FTC/TAF arm had an 8% lower infant-maternal folate ratio (0.92, 95%CI 0.78, 1.09) versus EFV/FTC/TDF. Results are consistent with no clinically meaningful differences between arms for all RBC-folate outcomes and they suggest that cellular uptake of folate and folate transport to the infant do not differ in pregnant women starting DTG- vs. EFV-based ART. |
Receipt of and satisfaction with school-based and virtual special education supports and therapeutic services during the COVID-19 pandemic
Spencer P , Verlenden JV , Kilmer G , Pampati S , Moore S , Rasberry CN , Claussen AH . J Online Learn Res 2024 10 (1) 91-112 The COVID-19 pandemic impacted school-based delivery of special educational supports and therapeutic services. This study describes student receipt of school-based supports/services and parent satisfaction by instruction modalities during the 2020-2021 academic year in the United States. Data were collected through the COVID Experiences Survey from parents of children ages 5-12 years, administered using NORC's AmeriSpeak panel. Most parents reported satisfaction with supports (88.4%) and services (93.2%). Dissatisfaction with special education supports and therapeutic services was more common among parents whose children received supports/services virtually than in person (special educational supports: aOR=12.00, 95% CI [1.49-96.89], p=0.020; therapeutic services: aOR=15.76, 95% CI [1.01-245.40], p=0.049). These findings suggest opportunities to improve design and delivery of online special education supports and therapeutic services as well as emergency preparedness by considering the needs of students with disabilities and their families. |
Quantification of mechanical behavior of rat tail under compression
Moore KD , Wu JZ , Krajnak K , Warren C , Dong RG . Biomed Mater Eng 2024 BACKGORUND: The development of vibration-induced finger disorders is likely associated with combined static and dynamic responses of the fingers to vibration exposure. To study the mechanism of the disorders, a new rat-tail model has been established to mimic the finger vibration and pressure exposures. However, the mechanical behavior of the tail during compression needs to be better understood to improve the model and its applications. OBJECTIVE: To investigate the static and time-dependent force responses of the rat tail during compression. METHODS: Compression tests were conducted on Sprague-Dawley cadaver rat tails using a micromechanical system at three deformation velocities and three deformation magnitudes. Contact-width and the time-histories of force and deformation were measured. Additionally, force-relaxation tests were conducted and a Prony series was used to model the force-relaxation behavior of the tail. RESULTS: The rat tails' force-deformation and stiffness-deformation relationships were strongly nonlinear and time-dependent. Force/stiffness increased with an increase in deformation and deformation velocity. The time-dependent force-relaxation characteristics of the tails can be well described using a Prony series. CONCULSIONS: We successfully quantified the static and time-dependent force responses of rat tails under compression. The identified mechanical behavior of the tail can help improve the rat-tail model and its applications. |
Feasibility, safety, and impact of the RTS,S/AS01(E) malaria vaccine when implemented through national immunisation programmes: evaluation of cluster-randomised introduction of the vaccine in Ghana, Kenya, and Malawi

Lancet 2024 403 (10437) 1660-1670 BACKGROUND: The RTS,S/AS01(E) malaria vaccine (RTS,S) was introduced by national immunisation programmes in Ghana, Kenya, and Malawi in 2019 in large-scale pilot schemes. We aimed to address questions about feasibility and impact, and to assess safety signals that had been observed in the phase 3 trial that included an excess of meningitis and cerebral malaria cases in RTS,S recipients, and the possibility of an excess of deaths among girls who received RTS,S than in controls, to inform decisions about wider use. METHODS: In this prospective evaluation, 158 geographical clusters (66 districts in Ghana; 46 sub-counties in Kenya; and 46 groups of immunisation clinic catchment areas in Malawi) were randomly assigned to early or delayed introduction of RTS,S, with three doses to be administered between the ages of 5 months and 9 months and a fourth dose at the age of approximately 2 years. Primary outcomes of the evaluation, planned over 4 years, were mortality from all causes except injury (impact), hospital admission with severe malaria (impact), hospital admission with meningitis or cerebral malaria (safety), deaths in girls compared with boys (safety), and vaccination coverage (feasibility). Mortality was monitored in children aged 1-59 months throughout the pilot areas. Surveillance for meningitis and severe malaria was established in eight sentinel hospitals in Ghana, six in Kenya, and four in Malawi. Vaccine uptake was measured in surveys of children aged 12-23 months about 18 months after vaccine introduction. We estimated that sufficient data would have accrued after 24 months to evaluate each of the safety signals and the impact on severe malaria in a pooled analysis of the data from the three countries. We estimated incidence rate ratios (IRRs) by comparing the ratio of the number of events in children age-eligible to have received at least one dose of the vaccine (for safety outcomes), or age-eligible to have received three doses (for impact outcomes), to that in non-eligible age groups in implementation areas with the equivalent ratio in comparison areas. To establish whether there was evidence of a difference between girls and boys in the vaccine's impact on mortality, the female-to-male mortality ratio in age groups eligible to receive the vaccine (relative to the ratio in non-eligible children) was compared between implementation and comparison areas. Preliminary findings contributed to WHO's recommendation in 2021 for widespread use of RTS,S in areas of moderate-to-high malaria transmission. FINDINGS: By April 30, 2021, 652 673 children had received at least one dose of RTS,S and 494 745 children had received three doses. Coverage of the first dose was 76% in Ghana, 79% in Kenya, and 73% in Malawi, and coverage of the third dose was 66% in Ghana, 62% in Kenya, and 62% in Malawi. 26 285 children aged 1-59 months were admitted to sentinel hospitals and 13 198 deaths were reported through mortality surveillance. Among children eligible to have received at least one dose of RTS,S, there was no evidence of an excess of meningitis or cerebral malaria cases in implementation areas compared with comparison areas (hospital admission with meningitis: IRR 0·63 [95% CI 0·22-1·79]; hospital admission with cerebral malaria: IRR 1·03 [95% CI 0·61-1·74]). The impact of RTS,S introduction on mortality was similar for girls and boys (relative mortality ratio 1·03 [95% CI 0·88-1·21]). Among children eligible for three vaccine doses, RTS,S introduction was associated with a 32% reduction (95% CI 5-51%) in hospital admission with severe malaria, and a 9% reduction (95% CI 0-18%) in all-cause mortality (excluding injury). INTERPRETATION: In the first 2 years of implementation of RTS,S, the three primary doses were effectively deployed through national immunisation programmes. There was no evidence of the safety signals that had been observed in the phase 3 trial, and introduction of the vaccine was associated with substantial reductions in hospital admission with severe malaria. Evaluation continues to assess the impact of four doses of RTS,S. FUNDING: Gavi, the Vaccine Alliance; the Global Fund to Fight AIDS, Tuberculosis and Malaria; and Unitaid. |
Guidelines for tuberculosis screening and preventive treatment among pregnant and breastfeeding women living with HIV in PEPFAR-supported countries
Hirsch-Moverman Y , Hsu A , Abrams EJ , Killam WP , Moore B , Howard AA . PLoS One 2024 19 (4) e0296993 BACKGROUND: Tuberculosis (TB) preventive treatment (TPT) is recommended by the World Health Organization (WHO) for persons living with HIV, including pregnant and breastfeeding women. Given the President's Emergency Plan for AIDS Relief (PEPFAR)'s investment in TPT services for persons living with HIV as a strategy to prevent TB as well as uncertainty in guidelines and policy regarding use of TPT during pregnancy and the postpartum period, we conducted a review of current relevant national guidelines among PEPFAR-supported countries. METHODS: Our review included 44/49 PEPFAR-supported countries to determine if TB screening and TPT are recommended specifically for pregnant and breastfeeding women living with HIV (WLHIV). National guidelines reviewed and abstracted included TB, HIV, prevention of vertical HIV transmission, TPT, and any other relevant guidelines. We abstracted information regarding TB screening, including screening tools and frequency; and TPT, including timing, regimen, frequency, and laboratory monitoring. RESULTS: Of 44 PEPFAR-supported countries for which guidelines were reviewed, 66% were high TB incidence countries; 41% were classified by WHO as high TB burden countries, and 43% as high HIV-associated TB burden countries. We found that 64% (n = 28) of countries included TB screening recommendations for pregnant WLHIV in their national guidelines, and most (n = 35, 80%) countries recommend TPT for pregnant WLHIV. Fewer countries included recommendations for breastfeeding as compared to pregnant WLHIV, with only 32% (n = 14) mentioning TB screening and 45% (n = 20) specifically recommending TPT for this population; most of these recommend isoniazid-based TPT regimens for pregnant and breastfeeding WLHIV. However, several countries also recommend isoniazid combined with rifampicin (3RH) or rifapentine (3HP). CONCLUSIONS: Despite progress in the number of PEPFAR-supported countries that specifically include TB screening and TPT recommendations for pregnant and breastfeeding WLHIV in their national guidelines, many PEPFAR-supported countries still do not include specific screening and TPT recommendations for pregnant and breastfeeding WLHIV. |
