The Chatbot Assessment Reporting Tool (CHART) is a reporting guideline developed to provide reporting recommendations for studies evaluating the performance of generative artificial intelligence (AI)-driven chatbots when summarizing clinical evidence and providing health advice, referred to as Chatbot Health Advice (CHA) studies. CHART was developed in several phases after performing a comprehensive systematic review to identify variation in the conduct, reporting and methodology in CHA studies. Findings from the review were used to develop a draft checklist that was revised through an international, multidisciplinary modified asynchronous Delphi consensus process of 531 stakeholders, three synchronous panel consensus meetings of 48 stakeholders, and subsequent pilot testing of the checklist. CHART includes 12 items and 39 subitems to promote transparent and comprehensive reporting of CHA studies. These include Title (subitem 1a), Abstract/Summary (subitem 1b), Background (subitems 2ab), Model Identifiers (subitem 3ab), Model Details (subitems 4abc), Prompt Engineering (subitems 5ab), Query Strategy (subitems 6abcd), Performance Evaluation (subitems 7ab), Sample Size (subitem 8), Data Analysis (subitem 9a), Results (subitems 10abc), Discussion (subitems 11abc), Disclosures (subitem 12a), Funding (subitem 12b), Ethics (subitem 12c), Protocol (subitem 12d), and Data Availability (subitem 12e). The CHART checklist and corresponding methodological diagram were designed to support key stakeholders including clinicians, researchers, editors, peer reviewers, and readers in reporting, understanding, and interpreting the findings of CHA studies.

Centers for Disease Control and Prevention's (CDC) Project Firstline is a national training collaborative launched during the COVID-19 pandemic to strengthen infection control knowledge among frontline healthcare workers (HCWs). Project Firstline collaborates with multidisciplinary partners to deliver educational resources and promote engagement on infection control topics for the healthcare workforce. In 2021, Project Firstline expanded its focus to include community colleges, where many HCWs are trained. The initiative brought together faculty from varied healthcare professions in a summer intensive program designed to foster peer-to-peer learning and curriculum review while emphasizing the "why" behind infection control practices. CDC learned from participants about the need for flexible approaches, variation in the perceived value of teaching infection control topics across professions, and importance of employer engagement in student education. Ultimately, this effort emphasized the crucial role community colleges play in fostering a culture of infection control expertise across healthcare professions.

INTRODUCTION: Associations between screen time and health outcomes among teenagers are well established. However, most studies use parent-reported information, which may misrepresent the magnitude or nature of these associations. In addition, timely nationally representative estimates are needed to correspond with evolving screen use. This study aimed to address these gaps by using data from a nationally representative survey of teenagers. METHODS: Data came from the 2021-2023 National Health Interview Survey-Teen (NHIS-Teen), a follow-back web-based survey designed to collect health information directly from teenagers aged 12 to 17 years. NHIS-Teen provides a unique opportunity to assess teenagers' self-reported health in conjunction with a rich set of parent-reported covariates, including family income, from the National Health Interview Survey. This study examines associations between high daily non-schoolwork screen time, defined as 4 or more hours of daily screen time, and adverse health outcomes across the domains of physical activity, sleep, weight, mental health, and perceived support. RESULTS: Teenagers with higher non-schoolwork screen use were more likely to experience a series of adverse health outcomes, including infrequent physical activity, infrequent strength training, being infrequently well-rested, having an irregular sleep routine, weight concerns, depression symptoms, anxiety symptoms, infrequent social and emotional support, and insufficient peer support. CONCLUSION: Results of this study include associations between high screen time and poor health among teenagers using self-reported data. Future work may further investigate these associations and their underlying mechanisms, including the content viewed on screens and the interactions taking place across screens.

West Nile virus (WNV) causes thousands of arboviral infections in the United States each year. Patients with immune-compromising conditions and elderly people are at higher risk of severe WNV neuroinvasive disease (WNND). Despite its broad endemicity nationwide, no U.S. Food and Drug Administration-approved vaccine or therapeutic treatments exist. We summarized existing peer-reviewed literature on the preclinical development of monoclonal antibody (MAb) prophylaxis and therapeutics for the prevention and treatment of WNND. Five bibliographical databases (CINAHL, Cochrane Library, Embase, MEDLINE, and Scopus) were searched for applicable research studies performed from 1 January 1998 to 1 May 2025. In total, 2347 titles and abstracts were screened, 263 full-text publications reviewed, and 25 studies included. Studies included detailed preclinical development and evaluations of MAbs targeting the envelope (E) protein (n = 13), other viral proteins (n = 3), flaviviral cross-protective monoclonal antibodies (n = 4), and novel antibody configurations or delivery methods (n = 5). The most well-studied MAb, E16, targeting E- Domain III (E-DIII), was effective at inhibiting and treating WNND in experimental animal models. No work investigated ways to traffic therapeutic antibodies across the blood-brain barrier. This review summarizes the current research in the development of monoclonal antibody therapeutics for WNV and addresses gaps in the knowledge for future consideration.

OBJECTIVES: Risks and priorities change during the management of public health incidents. Here we describe a new tool, the Incident Management Measurement Tool (IMMT), that can be used to inform midcourse corrections during public health emergencies and realistic exercises. METHODS: We developed the IMMT through a literature review and subject matter expert interviews. We field tested the tool in 23 incidents ranging in size, duration, and complexity, making changes based on user feedback. RESULTS: The IMMT consists of 2 modular data collection methods, a survey of the incident management team and a protocol for a peer assessor. Pilot testing suggested that the tool is valid, reliable, feasible, and useful. CONCLUSIONS: Measurement of public health incident management is feasible and may be useful for improving response times and outcomes. Moreover, a limited set of standard measures is relevant to a wide range of incident response contexts.

Our study applied the INSPIRE Framework - the WHO's 2016 technical package of evidence-based interventions for addressing violence against children - to identify accelerators for youth in Namibia. Accelerators are protective factors that contribute toward achieving multiple SDG targets. Using nationally representative data from the 2019 Namibia Violence Against Children & Youth Survey (n = 5167), three hypothesised accelerators (food security, parental support, and gender-equitable attitudes) were investigated for their impact on 12 adolescent outcomes. Associations between the hypothesised accelerators and outcomes were assessed using multivariable logistic regressions, and adjusted probabilities, differences, and ratios. Among girls, food security, gender-equitable attitudes, and parental support were accelerators, being associated with lower odds for 8, 6, and 2 outcomes, respectively. When all three were present, the combination was significantly associated with 10 out of 12 outcomes, including >75% lower prevalences of child marriage; > 50% lower prevalences of child abuse, sexual violence victimisation, early sexual debut/early pregnancy, and peer violence victimisation; and >25% lower prevalences of intimate partner violence (IPV) victimisation, not being in school or paid work, mental health distress, inconsistent condom use, and age-disparate or transactional sex. Among boys, gender-equitable attitudes was an accelerator and was significantly associated with 7 out of 10 outcomes, including approximately 50% lower prevalences of sexual violence victimisation, child abuse, age-disparate or transactional sex, IPV victimisation, multiple sexual partners, peer violence victimisation, and inconsistent condom use. Adolescents (especially girls) with access to INSPIRE provisions experience lower rates of violence and HIV-related risks. Implementing interventions on these priority protective factors could accelerate progress in achieving the SDGs for adolescents and young people in Namibia.

BACKGROUND: High-grade Plasmodium falciparum resistance to sulfadoxine-pyrimethamine in east and southern Africa has prompted trials evaluating intermittent preventive treatment in pregnancy (IPTp) with dihydroartemisinin-piperaquine as an alternative to sulfadoxine-pyrimethamine. We aimed to provide an updated and comprehensive review of trials conducted in areas of high P. falciparum resistance that compared the efficacy of two types of IPTp regimens on maternal, birth, and infant outcomes. METHODS: We conducted two-stage, individual participant data meta-analyses of randomised trials comparing IPTp with dihydroartemisinin-piperaquine to sulfadoxine-pyrimethamine on maternal, birth, and infant outcomes. We searched the WHO International Clinical Trials Registry Platform, ClinicalTrials.Gov, PubMed, and the Malaria in Pregnancy Consortium Library, on July 30, 2020 (updated on September 24, 2024), without restrictions by publication date, peer-review status, or language. Eligible trials enrolled HIV-uninfected pregnant women, followed participants to delivery, included participants with no prior IPTp use during the current pregnancy, and were conducted in areas with high-level parasite resistance to sulfadoxine-pyrimethamine (i.e., PfDHPS 540E ≥ 90% and/or 581G>0%). Only singleton pregnancies were analysed. The primary endpoint was a composite measure of any adverse pregnancy outcome defined as fetal or neonatal loss, small-for-gestational age, low birthweight, or preterm birth. Summary estimates were generated using a random-effects model. Gravidity subgroup analyses were performed. Causal mediation analyses were used to investigate the maternal mechanisms underlying the effect of IPTp regimens on birth outcomes. The meta-analysis is registered in PROSPERO (CRD42020196127). FINDINGS: Of 85 screened records, six trials (one multi-country trial) from Kenya, Malawi, Uganda and Tanzania contributed data on 6646 pregnancies. Compared to sulfadoxine-pyrimethamine, dihydroarteminsinin-piperaquine was associated with a 69% [95% CI: 45%-82%] lower incidence of clinical malaria during pregnancy, a 62% [37%-77%] lower risk of placental parasitaemia, and a 17% [0%-31%] lower incidence of moderate maternal anaemia. In contrast, sulfadoxine-pyrimethamine was associated with higher mean maternal weight gain (34 g/week [17-51]). There were no statistically significant differences in the composite adverse pregnancy outcome (RR = 1.05 [0.92-1.19]; I (2) = 48%). Individual components of the primary outcome showed no statistically significant differences in the risks of fetal loss (RR = 0.94 [0.61-1.46]), preterm birth (RR = 0.93 [0.76-1.14]), low birthweight (RR = 1.09 [0.83-1.43]), or neonatal loss (RR = 0.73 [0.42-1.26]), though findings may have been underpowered. Small-for-gestational-age risk was 15% (3%-24%) lower in the sulfadoxine-pyrimethamine arm, particularly among multigravidae (a 22% reduction vs 9% in primigravidae). Among multigravidae, infant stunting and underweight by two months was 20% [8%-30%] and 35% [17%-49%] lower in the sulfadoxine-pyrimethamine arm compared to dihydroartemisinin-piperaquine. Compared to dihydroartemisinin-piperaquine, sulfadoxine-pyrimethamine was associated with higher mean newborn birthweight (mean difference (MD) = 50 g [95% CI: 13-88]; p = 0.0090, I(2) = 61%) and BWGA z-scores (MD = 0.12 [95% CI: 0.05-0.20]; p = 0.0012, I(2) = 51%), but not gestational age at birth (MD = 0 weeks [95% CI: -0.11 to 0.12]; p = 0.94; I(2) = 42%). Infant wasting by two months was 13% [3%-22%] lower in the sulfadoxine-pyrimethamine arm, regardless of gravidity. Mediation analyses indicated that 15% [0%-19%] of sulfadoxine-pyrimethamine's superior effect on small-for-gestational-age risk was mediated by its greater impact on gestational weight gain. INTERPRETATION: In areas with high P. falciparum sulfadoxine-pyrimethamine resistance, dihydroartemisinin-piperaquine offers superior antimalarial efficacy than sulfadoxine-pyrimethamine. However, replacing sulfadoxine-pyrimethamine with dihydroartemisinin-piperaquine alone may not lead to improved maternal and infant health outcomes. Instead, it could result in slightly reduced gestational weight gain and a modest increase in the risk of small-for-gestational age births, and poor infant growth by two months of age. Future research evaluating alternative strategies for IPTp are needed. FUNDING: This work was supported by the Bill and Melinda Gates Foundation and Eunice Kennedy Shriver National Institute of Child Health and Human Development.

BACKGROUND: Caregiver barriers to accessing immunizations are a key factor influencing childhood vaccination. In preparation for the rollout of the second dose measles-containing vaccine (MCV2) in Uganda in October 2022, we aimed to identify possible barriers specific to female caregivers that could influence MCV2 implementation and suggest initiatives to facilitate MCV2 uptake. METHODS: In September 2022, we conducted a rapid community assessment in 18 districts in Uganda. We conducted key informant interviews with 17 district health managers and 18 community leaders, and 18 focus group discussions, one in each district, with caregivers of immunization-eligible children. We conducted a rapid analysis based of debriefing notes and in-depth thematic analysis of translated transcripts. Data were analyzed using NVivo version 12, wherein we used the framework analysis approach to define and structure codes deductively and inductively to identify themes. We mapped themes onto the socio-ecological model to examine factors that influence immunization at individual, household, community, and health system level. RESULTS: We found that individual, household, and health system factors influenced childhood vaccination and could be potential barriers to MCV2 uptake. At the individual level, female caregiver's heavy workload and limited decision-making power hindered their ability to take children for vaccination, with mothers often relying on fathers and depended on men for transport costs to immunization centers. At the household level, participants mothers were primarily responsible for taking children to vaccination centers, while fathers were less involved in child health. Health workers often gave preferential treatment to fathers over mothers at the health facility when they brought the child in for vaccination Participants suggested that approaches that ensure the involvement of fathers, other family members and mother-to-mother peer groups could address the barriers specific to female caregivers. CONCLUSION: Role differentiation between female and male caregivers affect childhood vaccination practices within communities in Uganda, potentially exacerbating challenges in accessing vaccines for children in the second year of life. Integrating interventions responsive to specific caregiver needs and that improve family participation may improve childhood vaccination in Uganda.

INTRODUCTION: This paper is a systematic review of evidence from economic evaluations of family-based interventions that was recommended by the Community Preventive Services Task Force (CPSTF) to prevent substance use among youth. METHODS: The search covered studies published from inception of databases through October 2023 and was limited to those based in the United States (U.S.) and other high-income countries. The present review reports results from peer-reviewed studies and government reports as separate sources of evidence. Analyses were conducted during June 2023 through September 2024. Monetary values are in 2023 U.S. dollars. RESULTS: The search yielded 11 peer-reviewed studies and two government reports, one from the Washington State Institute for Public Policy (WSIPP) that evaluated 14 programs and one from the Substance Abuse and Mental Health Administration (SAMHSA) that evaluated 8 programs. The median intervention cost ranged from $655 to $1,672 per family and $677 to $753 per youth or participant across the 3 sources of evidence. The median benefit to cost ratio were 5.8, 3.9, and 8.9 from peer-reviewed studies, WSIPP, and SAMHSA, respectively, with all three estimates indicating that benefits exceed cost. SAMHSA's report found some interventions to be cost-saving and the others to have a median cost per quality-adjusted life years (QALY) gained of $21,426. DISCUSSION: CPSTF determined cost-benefit evidence across the three sources showed societal benefits exceeded cost of family-based interventions to prevent substance use among youth. CPSTF determined there were not enough peer-reviewed studies to reach a conclusion about cost-effectiveness.

BACKGROUND: Firefighters are at an increased risk of cancer and other health conditions compared with the general population. However, the specific exposures and mechanisms contributing to these risks are not fully understood. This information is critical to formulate and test protective interventions. OBJECTIVE: The purpose of the Fire Fighter Cancer Cohort Study (FFCCS) is to conduct community-engaged research with the fire service to advance the evaluation and reduction of firefighter exposures, along with understanding and mitigating effects leading to an increased risk of cancer and other health conditions. This involves establishing a long-term (>30 years) firefighter multicenter prospective cohort study. METHODS: The structure of the FFCCS includes a fire service oversight and planning board to provide guidance and foster communication between researchers and fire organizations; a data coordinating center overseeing survey data collection and data management; an exposure assessment center working with quantitative exposure data to construct a firefighter job exposure matrix; and a biomarker analysis center, including a biorepository. Together, the centers evaluate the association between firefighter exposures and toxic health effects. Firefighter research liaisons are involved in all phases of the research. The FFCCS research design primarily uses a set of core and project-specific survey questions accompanied by a collection of biological samples (blood and urine) for the analysis of biomarkers of exposure and effect. Data and samples are collected upon entry into the study, with subsequent collection after eligible exposures, and at intervals (eg, 1-2 years) after enrollment. FFCCS data collection and analysis have been developed to evaluate unique exposures for specific firefighter groups; cancer risks; and end points in addition to cancer, such as reproductive outcomes. Recruitment is carried out with coordination from partnering fire departments and eligible participants, including active career and volunteer firefighters in the United States. RESULTS: The FFCCS protocol development was first funded by the US Federal Emergency Management Agency in 2016, with enrollment beginning in February 2018. As of September 2024, >6200 participants from >275 departments across 31 states have enrolled, including recruit and incumbent firefighters. Biological samples have been analyzed for measures of exposure and effect. Specific groups enrolled in the FFCCS include career and volunteer structural firefighters, women firefighters, trainers, fire investigators, wildland firefighters, firefighters responding to wildland-urban interface fires, and airport firefighters. Peer-reviewed published results include measurement of exposures and the toxic effects of firefighting exposure. Whenever possible, research results are provided back to individual participants. CONCLUSIONS: The FFCCS is a unique, community-engaged, multicenter prospective cohort study focused on the fire service. Study results contribute to the evaluation of exposures, effects, and preventive interventions across multiple sectors of the US fire service, with broad implications nationally.

INTRODUCTION: Although preventable, dental caries remains highly prevalent. Many children do not receive preventive dental services routinely in clinical settings. This review examined the effectiveness of school (preschool through high school) fluoride varnish delivery programs (SFVDP) in preventing caries. METHODS: Community Guide systematic review methods were followed. In 2024, databases were searched for studies published through December 2023 on SFVDP effectiveness in increasing fluoride varnish (FV) receipt and decreasing caries. Included studies had to be written in English, published in peer-reviewed journals, and conducted in upper-middle or high-income countries. Data synthesis conducted in 2024 used median RR and interquartile interval (IQI) to summarize findings across studies. RESULTS: Of 31 included studies with 60,780 students, 25 were randomized controlled trials-20 with good quality of execution. Most studies were conducted in low socioeconomic status (SES) areas among students at elevated caries risk. SFVDP reduced caries initiation by 32% (IQI: 21%, 37%) in permanent teeth (19 studies, 25,826 students) and by 25% (IQI: 4%, 37%) in primary teeth (12 studies, 4,304 students). Stratified assessments indicated findings were largely applicable to different settings, populations, and intervention characteristics. Two studies found SFVDP significantly increased the number of annual FV applications and two found that SFVDP effectiveness was inversely related to SES. DISCUSSION: About 30% of states report having no SFVDPs. Possible barriers to implementation include that Medicaid in some states only reimburses dental and medical professionals and does not reimburse non-dental providers for FV delivered to children older than 6 years.

OBJECTIVE: Promoting health during adolescence can support long-term well-being, especially for teens diagnosed with attention-deficit/hyperactivity disorder (ADHD), who face increased risks due to the disorder's impact on development and health behaviors. ADHD is often associated with difficulties in social interactions, a higher likelihood of bullying involvement, and co-occurring mental health conditions. These factors may also be influenced by health factors such as physical activity, sleep quality, and screen time usage. Nationally representative teen self-reports provide a novel perspective on ADHD-related health outcomes compared with relying on parent reports. METHOD: We used nationally representative data from the National Health Interview Survey (NHIS) and NHIS-Teen from July 2021 to December 2022, to examine teen-reported health and well-being factors, stratified by parent-reported ADHD diagnoses among teens aged 12 to 17 years. Weighted prevalence estimates and adjusted prevalence ratios (aPR) adjusting for teen age, sex, and family income, all with 95% confidence intervals (CIs), were calculated. RESULTS: Just over 10% of teens had ADHD and they reported higher prevalence of bullying victimization (aPR = 1.64, CI = 1.27-2.11), difficulties making friends (aPR = 1.83, CI = 1.15-2.90), difficulty getting out of bed (aPR = 1.29, CI = 1.02-1.64), irregular wake times (aPR = 2.17, CI = 1.45-3.25), and >4 hours daily screen time (aPR = 1.26, CI = 1.05-1.52) than teens without ADHD; teens with ADHD reported a lower prevalence of lacking peer support (aPR = 0.70, CI = 0.51-0.96). CONCLUSION: Teens with ADHD face distinct challenges related to social-emotional well-being and health behaviors that support overall wellness. Findings may inform opportunities for health promotion among teens with ADHD.

OBJECTIVE: The National Association of Chronic Disease Directors (NACDD) is a nonprofit organization that supports state and territorial chronic disease prevention and health promotion efforts through capacity building and technical assistance. Each year, NACDD surveys health department leaders who oversee chronic disease prevention and health promotion (hereafter, Chronic Disease Directors). We have previously used the annual survey results to inform strategic planning and resource allocation but have not historically published key findings in the peer-reviewed literature. In this paper, we report on NACDD's 2023 survey outcomes and place those findings into the broader public health policy context. DESIGN: State Chronic Disease Directors completed a survey about their organizational capacity and development needs. Responses were summarized in aggregate and by jurisdiction size. RESULTS: State chronic disease units have varied staffing and responsibilities, but most address diabetes, cardiovascular diseases, and cancer screening and prevention. Chronic Disease Directors generally reported strong or improving capacity in most practice areas but ranked workforce development lower. Staffing increased slightly during 2023 compared with the 2020 baseline (median of 1.3 and 1.1 employees per 100 000 jurisdiction population, respectively). However, Chronic Disease Directors expressed ongoing concerns about turnover, hiring, and training of inexperienced staff, as well as about funding limitations and uncertainty. Looking forward to 2024, many Chronic Disease Directors expressed intentions to focus on supporting their workforce with training and development opportunities and addressing health equity. CONCLUSIONS: During this period of pandemic recovery, turnover, hiring, and training-particularly of the many new public health staff-remain key areas of concern for many chronic disease units. Continued stabilization of public health funding and increased prioritization of organizational capacity development-particularly workforce development, chronic disease data systems, and tools for addressing health equity-could help ensure chronic disease units can better address current and emerging challenges in chronic disease prevention and health promotion.

BACKGROUND: It is estimated that over 111,000 people in the U.S. died from a drug overdose in the twelve-month period ending in July 2023. More than three-quarters of those deaths were attributed to opioids. Naloxone has long been available in healthcare facilities to reverse opioid overdose rapidly and safely but is not universally accessible for use in community settings where overdoses occur. We conducted a systematic literature review and meta-analysis to assess the effectiveness of overdose education and naloxone distribution (OEND) programs in three types of community settings to reduce overdose deaths among people who use opioids nonmedically. METHODS: We systematically searched electronic databases, including Medline (OVID), Embase (OVID), Psycinfo (OVID), and Global Health (OVID), for peer-reviewed studies of OEND programs published during 2003-2018 (Group 1) that reported overdose outcomes individual level survivals or deaths immediately following naloxone administration. The PRISMA checklist guided screening, quality assessment, and data abstraction. We later identified studies published during 2018-2022 (Group 2), when drug usage and fentanyl-related overdose deaths notably increased, differed from earlier ones. We conducted meta-analyses on both Groups using random effects models to estimate summary survival proportions. RESULTS: Among the 44 Group 1 studies published during 2003-2018, survival did not differ by time (year), location, naloxone dose, or route of administration, but studies of OEND programs serving people who use drugs reported 98.3% (95% CI: 97.5-98.8) survival; those serving family of people who use drugs or other community members reported 95.0% (95% CI: 91.4-97.1) survival; and those for police reported 92.4% (95% CI: 88.9-94.8) survival (p < 0.01). Five Group 2 studies (2018-2022) yielded similar results. CONCLUSIONS: Community-based naloxone distribution programs can be effective in preventing opioid overdose deaths. The paper demonstrates that in the face of increasing overdose deaths over time, survival after naloxone administration has been sustained. The very high survival rates provide clear evidence for public health to continue efforts to expand channels for naloxone distribution in community settings.

Uganda implements interventions for injection drug use, but significant barriers hinder efforts to effectively reach and support persons who inject drugs (PWID). We describe characteristics of PWID, and associated risk behaviour, to inform the designing of programmes that are tailored to clients' needs and preferences. A cross-sectional survey (August 23rd to December 5th, 2023) in Kampala interviewed 354 PWID (≥18-years) at selected venues(bars,lodges, street corners and ghetto). Peer eductors and counsellors administered a structured questionnaire covering socio-demographics, drug use, sexual risk, and medical history. HIV serostatus was determined by self-report or testing for consenting participants without history of recent testing Binary logistic regression was used to establish the relationship between HIV infection and risky drug- and sexual behaviour of PWID. Participants were predominantly Ugandan (95.2%), male (73.2%), unmarried (55.9%), unemployed (81.8%), with higher levels of education and varying ages. Mental disorders were prevalent, with 48.7% reporting at least one underlying condition, including depression (30.8%) and anxiety (9.6%). Physical health issues included fever (32.9%), cough (32.5%), malaria (22%), and sexually transmitted infections (15%). Over 82.6% were introduced to drugs by close acquaintances. HIV prevalence among participants was 3.7%, higher in females (8.4%) and non-Ugandans (16.7%). Being female and experiencing difficulty accessing sterile injection materials were associated with HIV-positive status. Our study provides valuable insight into the socio-demographic, mental, physical health, and HIV risk behaviour of PWID in Kampala, Uganda. The findings indicate significant vulnerabilities to injecting drug use, mental disorders, and high-risk behaviors that predispose this population to HIV infection. Despite a low HIV prevalence in this population compared to previous estimates, the interplay between drug use, risky injecting practices, and sexual behaviour suggests an urgent need for targeted interventions to address these intertwined challenges.

Mosquito control using pyrethrins and synthetic pyrethroids (PSP) is important for preventing vector-borne diseases. Although the benefits associated with PSP use are well-documented, public concern exists regarding potential human adverse health effects. The aim of this scoping review was to describe adverse human health effects associated with PSP use for community adult mosquito control. A literature search using the databases MEDLINE, EMBASE, Agricultural and Environmental Science Collection, CAB Abstracts, and Scopus obtained 6,154 original peer-reviewed articles published during 1 January 2000 to 22 May 2024. Articles were independently reviewed for inclusion using predetermined exclusion and inclusion criteria. Data were extracted from 10 included articles. Study designs included cohort (n = 5), cross-sectional (n = 2), and risk assessment (n = 4). One article included 2 study designs. Of the cohort studies, one was prospective and the remainder were retrospective. A causal relationship between PSP application for adult mosquito control and adverse human health impacts was not identified. No increases in acute health manifestations were reported. The 4 risk assessments estimated that PSP exposures were not above the regulatory level of concern; a meta-analysis determined the likelihood of PSP exposures exceeding the regulatory level of concern was <0.0001. The limited evidence indicated that PSP applied appropriately for control of nuisance mosquitoes or mosquitoes that transmit arboviruses do not pose acute or chronic human health risks. Continued investigation into potential human health impacts of PSP would help inform guidelines for adult mosquito control and help inform public health decision making.

We present a laboratory module that uses isolation of antibiotic-resistant bacteria from locally collected stream water samples to introduce undergraduate students to basic microbiological culture-based and molecular techniques. This module also educates them on the global public health threat of antibiotic-resistant organisms. Through eight laboratory sessions, students are involved in quality testing of water sources from their neighborhoods, followed by isolation of extended-spectrum beta-lactamase-producing Enterobacteriaceae. By the end of the module, students should be able to isolate Enterobacteriaceae from the environment using selective and differential media, identify isolates using biochemical tests, characterize antibiotic resistance phenotypes using Kirby Bauer and MIC tests, and evaluate the presence of select beta-lactamase genes of interest using PCR. To complement laboratory sessions, students participated in a weekly flipped classroom session with collaborative peer discussions and activities to reinforce concepts applied in the laboratory. Learning outcomes were measured over four semesters with concept checks, in-lecture activities, exams, and laboratory reports. We hypothesized that more than 50% of the student population would achieve each learning objective through the implementation of this authentic research laboratory module. Here, we highlight specific questions used to assess learning objective comprehension and demonstrate that each learning objective was achieved by 65%-100% of the student population. We present a ready-to-adapt module with flexible resources that can be implemented in courses across disciplines in biology, microbiology, environmental sciences, and public health.

INTRODUCTION: Understanding sex and gender differences during outbreaks is critical to delivering an effective response. Although recommendations and minimum requirements exist, the incorporation of sex-disaggregated data and gender analysis into outbreak analytics and response for informed decision-making remains infrequent. A scoping review was conducted to provide an overview of the extent of sex-disaggregated data and gender analysis in outbreak response within low- and middle-income countries (LMICs). METHODS: Five databases were searched for peer-reviewed literature examining sex- and gender-specific outcomes for communicable disease outbreaks published in English between 1 January 2012 and 12 April 2022. An adapted version of the WHO's Gender Analysis Matrix was used to synthesise evidence, which was then mapped across four phases of the outbreak timeline: prevention, detection, treatment/management and recovery. RESULTS: 71 articles met inclusion criteria and were included in this review. Sex-, gender-, and pregnancy-related disparities were identified throughout all four phases of the outbreak timeline. These disparities encompassed a wide range of risk factors for disease, vulnerability, access to and use of services, health-seeking behaviour, healthcare options, as well as experiences in healthcare settings and health and social outcomes and consequences. CONCLUSION: Significant gender-evidence gaps remain in outbreak response. Evidence that is available illustrates that sex and gender disparities in outbreaks vary by disease, setting and population, and these differences play significant roles in shaping outbreak dynamics. As such, failing to collect, analyse or use sex-disaggregated data and gendered data during outbreaks results in less effective responses, differential adverse health outcomes, increased vulnerability among certain groups and insufficient evidence for effective prevention and response efforts. Systematic sex- and gender-based analyses to ensure gender-responsive outbreak prevention, detection, treatment/management and recovery are urgently needed.

Young Black women in the southern US face a high HIV burden. While daily oral HIV pre-exposure prophylaxis (PrEP) can effectively prevent HIV, its use is low among Black women. The acceptability of and perceived intention to use emerging PrEP products among young Black women in the southern US are not well understood. Non-oral PrEP alternatives could address challenges to PrEP uptake and reduce health disparities. We conducted virtual semi-structured interviews with Black women aged 18-34 in Atlanta, GA; Baton Rouge, LA; and Jackson, MS, to explore their perspectives on three emerging PrEP products: a long-acting injection, a subdermal implant, and a dual-purpose contraception and HIV prevention intravaginal ring. Seventy-five interviews were conducted from January to October 2021 and analyzed using inductive thematic analysis with NVivo software. Most participants were open to using medication to prevent HIV. The intravaginal ring was the most preferred, primarily due to its dual-purpose function, although it was also frequently rejected. The long-acting injection was the second most preferred and least rejected, perceived as the least invasive. The skin implant was the least preferred and most rejected, viewed as the most invasive. Our findings highlight the need for multiple PrEP options to meet individual preferences. Detailed descriptions, instructions, and experiential learning methods are crucial for choosing non-oral PrEP modalities. Practitioners should address questions and offer peer-based learning opportunities. Designing and promoting PrEP strategies for young Black women should involve close consultation with these consumers.

Telomere length (TL) predicts the onset of replicative senescence, and its shortening is a limiter on the number of divisions individual somatic cells can perform. Metal-induced genotoxic events are discussed in Agency for Toxic Substances and Disease Registry’s (ATSDR) toxicological profiles. In vivo and in vitro toxicological studies suggest the correlation between toxic metals and TL. However, the correlation between TL and exposure to toxic metals in human populations is unclear despite decades of observational research. We conducted a literature search within the ATSDR toxicological profiles and PubMed database for peer-reviewed articles as of 04/2023 discussing TL and metal exposure in human populations. Through review of the 272 publications meeting these criteria, we identified 25 observational studies that considered the correlation between TL and exposure to some or all of six metals: cadmium (Cd), arsenic (As), nickel (Ni), selenium (Se), lead (Pb), and cesium (Cs). Because reported effect sizes were often not comparable across studies, we performed a sign test based on the reported significance for each metal–TL correlation. We found that Cd was consistently significantly correlated with shorter telomeres (p = 0.016). However, no consistent linear relationship was observed between TL and any of the other metals considered. Exploring this association can enhance our understanding of how metal exposure may influence TL dysfunction. Our findings suggest that Cd exposure contributes to shorter TL, which may affect the DNA damage response (DDR) resulting in numerous chronic health conditions. Further, we highlight inconsistencies in findings on the correlation between metal exposure and TL across different populations and exposure levels. This suggests that correlations between some metals and TL may vary across populations, and that correlations may change at different exposure levels. Also, our findings suggest the need for further research on the potential for nonlinear relationships and non-additive effects of co-exposure to multiple hazardous metals, which could explain the inconsistencies observed across studies. The inconsistent incidences of metal–TL correlations justify additional exploration into the complex interaction between metals and TL. © 2024 by the authors.

OBJECTIVE: To explore the role of local public health organisations in antimicrobial stewardship (AMS) and antimicrobial resistance (AMR) surveillance. METHODS: A scoping review was conducted. Peer-reviewed and grey literature from countries within the organisation for economic co-operation and development was searched between 1999 and 2023 using the concepts of local public health, AMR and AMS. Thematic analysis was performed to identify themes. RESULTS: There were 63 citations illustrating 122 examples of AMS and AMR surveillance activities with local public health involvement. Common AMS activities (n = 105) included healthcare worker education (n = 22), antimicrobial use (AMU) evaluation (n = 21), patient/public education (n = 17), clinical practice guidelines (n = 10), and antibiograms (n = 10). Seventeen citations described local public health activities in AMR surveillance; the majority focussed on communicable diseases (n = 11) and/or AMR organisms (n = 6). CONCLUSIONS: Local public health capabilities should be leveraged to advance high-impact activities to mitigate AMR, particularly in the areas of knowledge translation/mobilisation, optimising surveillance and establishing strategic collaborations. POLICY IMPLICATIONS: Future work should focus on better understanding barriers and facilitators, including funding, to local public health participation in these activities.

BACKGROUND: To inform the delivery of cardiac rehabilitation (CR) care nationwide at the hospital level, we described hospital-level variation in CR metrics, overall and stratified by the hospital's tier of cardiac care provided. METHODS: This retrospective cohort analysis used Medicare fee-for-service (FFS) data (2018-2020), Parts A and B, and American Hospital Association (AHA) data (2018). We included beneficiaries with an acute myocardial infarction (AMI), percutaneous coronary intervention (PCI), or coronary artery bypass graft (CABG) in 2018, aged ≥65 years, and continuously enrolled in a FFS plan. We calculated hospital-level metrics for hospitals with ≥20 CR-qualifying events, which were identified using diagnostic/procedure codes. Claims for CR were identified by Healthcare Common Procedure Coding System (HCPCS) codes. We used multi-level models to examine patient- and hospital-level factors associated with CR metrics. Hospitals were stratified by tier of cardiac care provided (comprehensive, AMI/PCI, AMI-only care). RESULTS: Across the US, 2,212 hospitals treated individuals aged ≥65 years with a CR-qualifying event in 2018. By tier of cardiac care, 44.4% of hospitals provided comprehensive care, 31.2% provided AMI/PCI care, and 24.4% provided AMI-only care. Across all hospitals, there was substantial variation in CR enrollment (median 19.6%, interquartile range [IQR]=7.0%, 32.8%). Among hospitals with enrollment (n=1,866), median time to enrollment was 55.0 days (IQR=41.0, 71.0), median number of CR sessions was 26.0 (IQR=23.0, 29.0), and median percent completion was 26.0% (IQR=10.5%, 41.2%). There was also substantial variation in CR performance metrics among hospitals within each tier of cardiac care (e.g., median percent CR enrollment was 30.7% [IQR=20.7%-41.3%] among comprehensive care hospitals, 18.6% [IQR=9.5%-27.7%] among AMI/PCI hospitals, and 0.0% [IQR=0.0%-7.7%] among AMI-only hospitals). In adjusted analyses, characteristics associated with lower odds of CR enrollment included patient-level factors (older age, female sex, non-White race or ethnicity), and hospital-level factors (for-profit ownership, regions other than the Midwest, rural location, medium/large hospital size). CONCLUSIONS: This is the first national, hospital-level analysis of CR metrics among Medicare beneficiaries. Substantial variation across hospitals, including peer hospitals within the same tier of cardiac care, indicates opportunities for hospital-level quality improvement strategies to improve CR referral and participation metrics.

BACKGROUND: Respondent-driven sampling (RDS) is the current standard for sampling key populations at risk for HIV infections but is usually limited to local implementation in single towns or cities. Web-based sampling eliminates this spatial constraint but often relies on self-selected convenience samples. We piloted a web-based RDS survey with biomarker collection among men who have sex with men (MSM) in Thailand. OBJECTIVE: This study aimed to evaluate and demonstrate the feasibility of implementing a web-based RDS survey as a routine surveillance system in Thailand. The goal was to enhance surveillance efforts targeting hard-to-reach populations in the country. METHODS: We developed a website to fully function like a conventional RDS survey office, including coupon verification, eligibility screening, consenting, interviewing (self-administered), peer recruitment training, coupon issuance, compensation, and recruitment tracking. All functions were automated; data managers monitored recruitment, data collection, and payment and could be contacted by recruits as needed. Eligible participants were male, older than 15 years, resided in Thailand, and had anal sex with a man in the past 6 months. Recruits who resided in Bangkok were additionally invited to physically attend a participating health clinic of their choice for an HIV-related blood draw. Data were weighted to account for the complex sampling design. RESULTS: The survey was implemented from February to June 2022; seeds (21 at start, 14 added later) were identified mostly through targeted web-based banner ads; coupon uptake was 45.1%. Of 2578 candidate recruits screened for eligibility, 2151 (83.4%) were eligible and 2142 (83.1%) enrolled. Almost all (2067/2578, 80.2%) completed the questionnaire; however, 318 survey records were removed from analysis as fraudulent enrollments. The final sample size was 1749, the maximum number of waves achieved was 191, and sampling covered all 6 geographic regions and 75 of 77 (97.4%) provinces; convergence was reached for several salient variables. The mean age was 20.5 (SD 4.0) years, and most (69.8%) had never tested for HIV before, with fear of stigma as the biggest reason (97.1%) for not having tested. Most (76.9%) had visited gay-focused physical venues several times a week. A condom was used in 97.6% of the last sex acts, 11.0% had purchased sex from other men (past 12 mo), 4.5% had sold sex to men (past 12 mo), and 95.3% had 3+ male sex partners (last 3 mo). No participant in Bangkok presented for a blood draw. CONCLUSIONS: We successfully conducted a web-based RDS survey among MSM in Thailand, covering nearly the entire country, although, as in physical RDS surveys, sampling was dominated by younger MSM. The survey also failed to collect biomarkers in Bangkok. Public health interventions should aim at increasing testing and addressing (the perception of) stigma.

INTRODUCTION: Food and nutrition security is crucial for health, but many U.S. households experience food insecurity. This systematic review conducted in support of the Community Preventive Services Task Force (CPSTF) examines the effectiveness of Fruit and Vegetable Incentive (FVI) programs in reducing food insecurity, increasing fruit and vegetable (FV) consumption, and improving health outcomes among households with lower incomes. METHODS: Community Guide systematic review methods were applied. Studies were identified through a literature search (inception of each database to February 2023). U.S. studies were included if they evaluated programs offering participants financial incentives to purchase FV; were designed for or implemented among populations with lower incomes; reported health-related outcomes; and were published in English as peer-reviewed articles or government reports. RESULTS: This review included 30 studies. Thirteen of 14 datapoints from 12 studies indicated FVI programs reduced household food insecurity. Twenty-one of 29 datapoints from 23 studies showed increased FV consumption. Programs providing incentives to participants at risk for or with diet-related health conditions improved blood glucose levels by a median of 0.64 percentage points. DISCUSSION: Based on the review findings, CPSTF recommends FVI programs for populations with lower incomes to reduce household food insecurity, increase household FV consumption, and improve blood glucose levels in participants at risk for or with diet-related health conditions. Although the review did not find direct evidence of reducing health disparities, the CPSTF expects that these programs will improve health equity across the US by improving the affordability and accessibility of healthier foods for households with lower incomes.

Objective: The National Association of Chronic Disease Directors (NACDD) is a nonprofit organization that supports state and territorial chronic disease prevention and health promotion efforts through capacity building and technical assistance. Each year, NACDD surveys health department leaders who oversee chronic disease prevention and health promotion (hereafter, Chronic Disease Directors). We have previously used the annual survey results to inform strategic planning and resource allocation but have not historically published key findings in the peer-reviewed literature. In this paper, we report on NACDD’s 2023 survey outcomes and place those findings into the broader public health policy context. Design: State Chronic Disease Directors completed a survey about their organizational capacity and development needs. Responses were summarized in aggregate and by jurisdiction size. Results: State chronic disease units have varied staffing and responsibilities, but most address diabetes, cardiovascular diseases, and cancer screening and prevention. Chronic Disease Directors generally reported strong or improving capacity in most practice areas but ranked workforce development lower. Staffing increased slightly during 2023 compared with the 2020 baseline (median of 1.3 and 1.1 employees per 100 000 jurisdiction population, respectively). However, Chronic Disease Directors expressed ongoing concerns about turnover, hiring, and training of inexperienced staff, as well as about funding limitations and uncertainty. Looking forward to 2024, many Chronic Disease Directors expressed intentions to focus on supporting their workforce with training and development opportunities and addressing health equity. Conclusions: During this period of pandemic recovery, turnover, hiring, and training—particularly of the many new public health staff—remain key areas of concern for many chronic disease units. Continued stabilization of public health funding and increased prioritization of organizational capacity development—particularly workforce development, chronic disease data systems, and tools for addressing health equity—could help ensure chronic disease units can better address current and emerging challenges in chronic disease prevention and health promotion. © 2024 Lippincott Williams and Wilkins.

BACKGROUND AND OBJECTIVES: Respiratory syncytial virus (RSV) commonly causes hospitalization among US infants. A maternal vaccine preventing RSV in infants, RSV bivalent prefusion F maternal vaccine (RSVpreF), was approved by the US Food and Drug Administration and recommended by the Advisory Committee on Immunization Practices. Our objective was to evaluate the health benefits and cost-effectiveness of vaccinating pregnant persons in the United States using RSVpreF. METHODS: We simulated RSV infection and disease with and without seasonal RSVpreF vaccination in half of the pregnant persons in the annual US birth cohort during weeks 32 through 36 of gestation. Model inputs came from peer-reviewed literature, Food and Drug Administration records, and epidemiological surveillance databases. The results are reported using a societal perspective in 2022 US dollars for a 1-year time frame, discounting future health outcomes and costs at 3%. Sensitivity and scenario analyses were performed. RESULTS: Year-round maternal vaccination with RSVpreF would prevent 45 693 outpatient visits, 15 866 ED visits, and 7571 hospitalizations among infants each year. Vaccination had a societal incremental cost of $396 280 per quality-adjusted life-year (QALY) saved. Vaccination from September through January cost $163 513 per QALY saved. The most influential inputs were QALYs lost from RSV disease, the cost of the vaccine, and RSV-associated hospitalization costs; changes in these inputs yielded outcomes ranging from cost-saving to $800 000 per QALY saved. CONCLUSIONS: Seasonal maternal RSV vaccination designed to prevent RSV lower respiratory tract infection in infants may be cost-effective, particularly if administered to pregnant persons immediately before or at the beginning of the RSV season.

BACKGROUND: Private wells use groundwater as their source and their drinking water quality is unregulated in the United States at the federal level. Due to the lack of water quality regulations, those reliant on private wells have the responsibility of ensuring that the water is safe to drink. Where extreme weather is projected to increase with climate change, contamination due to climate-related hazards adds further layers of complexity for those relying on private wells. We sought to characterize community-level climate-related hazards and vulnerability for persons dependent on private wells in the continental United States (CONUS). Additional objectives of this work were to quantify the burden to private well water communities by climate regions and demographic groups. METHODS: Grounded in the latest climate change framework and private well water literature, we created the Private Well Water Climate Impact Index (PWWCII). We searched the literature and identified nationally consistent, publicly available, sub-county data to build Overall, Drought, Flood, and Wildfire PWWCIIs at the national and state scales. We adapted the technical construction of this relative index from the California Communities Environmental Health Screening Tool (CalEnviroScreen 4.0). RESULTS: The distribution of climate-related impact census tracts varied across CONUS by nationally-normed PWWCII type. Compared to the Southeast where the majority of the 2010 estimated U.S. private well water population lived, the estimated persons dependent upon private well water living in the West had an increased odds of living in higher impact census tracts for the Overall, Drought, and Wildfire PWWCIIs across CONUS. Compared to non-Hispanic White persons, non-Hispanic American Indian and Alaska Native (AI/AN) persons had an increased odds of living in higher impact census tracts for all four PWWCII types across CONUS. CONCLUSIONS: The PWWCII fills a gap as it provides a baseline understanding of potential climate-related impacts to communities reliant on private well water.

Papua New Guinea lacks data characterising the sexual health needs of younger key populations (KP): female sex workers (FSW) and commercially and sexually exploited girls (CSE), men who have sex with men (MSM), and transgender women (TGW). Biobehavioural surveys among KP were conducted in three cities. We conducted unweighted and weighted analysis for sample and population proportions, respectively. Variables associated with younger versus older age (15-24 versus ≥25 years) were included in the multivariable analysis. Younger FSW/CSEG had greater odds of having both Neisseria gonorrhoea and Chlamydia trachomatis (aOR:3.2, 95%CI 2.0-5.0), or having either infection (aOR:2.2, 95%CI 1.2-4.1) than older peers. They also had lower odds of having tested for HIV (aOR: 0.6, 95%CI 0.4-0.8). Younger MSM/TGW had greater odds of paying for sex in the <6 months (aOR:2.2, 95%CI: 1.5-3.1) and of having been paid for sex (aOR:1.6, 95%CI 1.1-2.4) than their older peers (≥25 years). Younger MSM/TGW had lower odds of having contact with a peer educator ≤12 months (aOR:0.6, 95%CI 0.4-0.9) and having tested for HIV (aOR:0.6, 95%CI: 0.4-0.9). All key populations have substantial sexual health needs, but those of younger members are greatest. Younger key populations would likely benefit from health services designed specifically for them.
