International guidelines are available for the assessment and improvement of antimicrobial stewardship (AMS) programmes: an important strategy to address the escalating global antimicrobial resistance problem. However, existing AMS assessment tools lack contextual specificity for resource-limited settings, leading to limited applicability in Asia. This project aimed to identify relevant themes from current guidance documents to help develop a context-specific assessment tool that can be applied by healthcare facilities (HCFs) to improve local implementation.We performed a sequential approach of a scoping review to identify relevant assessment themes for Asia and an expert survey for getting feedback on the relevance of assessment stems developed from the scoping review. We reviewed English-language published documents discussing AMS implementation or assessment at HCFs globally and in Asia. Themes were derived through content analysis and classified following the predefined context dimensions to develop assessment stems, defined as containing one identified determinant that may influence implementation outcomes. The survey consisting of identified assessment stems was reviewed by 20 locally identified experts in Asia who rated the level of relevance of these stems in AMS implementation in the region.National leadership, training and technical support, and policy and guidance were the most commonly identified themes among 100 themes identified from 73 reviewed documents. From these themes, we developed 131 assessment stems for the expert survey. Of the 131 assessment stems, 117 (89%) were considered relevant for AMS implementation in Asia by at least 80% of respondents. These stems were included in the process of developing a global AMS assessment tool to support HCFs to improve their programmes.In conclusion, national leadership and support represent a distinct and important aspect affecting AMS implementation in HCFs in Asia. The identified assessment themes have substantial value for the formulation of locally relevant implementation strategies tailored to the Asian context.

Human adenovirus (HAdV), especially HAdV species F (HAdV-F) is recognized as a cause of acute gastroenteritis (AGE) worldwide. To assess the global prevalence of HAdV in case-patients of all ages with AGE, we conducted a systematic literature search for studies published in English during 2015-2022. We generated pooled prevalence estimates using generalized linear mixed models. Using data from 147 included articles, the overall pooled prevalence among AGE case-patients of any species of HAdV (pan-HAdV) was 5.8 % and 6.0 % for HAdV-F. The prevalence of HAdV was significantly higher among case-patients < 5 years of age compared with case-patients ≥ 5 years of age (pan-HAdV: 6.6 % vs. 2.0 %, p < 0.0001; HAdV-F: 8.7 % vs. 2.3 %, p = 0.04). Prevalence was significantly higher in high mortality developing countries and lowest in developed countries (pan-HAdV: 9.4 % vs. 4.0 %, p < 0.0001; HAdV-F: 11.6 % vs. 3.2 %, p = 0.0003). Understanding the burden of HAdV-associated AGE may be useful for targeted interventions, including future vaccine development.

BACKGROUND: The Michigan Polybrominated Biphenyl (PBB) registry, followed since 1976, was created after a 1973 chemical manufacturing mistake. The flame retardant PBB was accidentally mixed into animal feed and distributed to Michigan farms for nearly a year, exposing farm residents and animal product consumers. OBJECTIVE: We synthesize knowledge to date on health effects of PBB exposure within the Michigan PBB Registry, and describe research findings in the context of literature on other persistent organic pollutants (POPs) and endocrine disrupting chemicals (EDCs). METHODS: We reviewed literature published from 1973-2025 on human health effects of PBB following the Michigan contamination using PubMed and Thompson Reuters (ISI) Web of Science databases. We excluded studies not in English; on exposures besides PBB; animal studies; reviews, abstracts, or letters to the editor; studies without a health outcome; and studies outside of Michigan or unrelated to the 1973 contamination. For each article, two researchers performed title and abstract screening, full article review, and data extraction. RESULTS: We included 79 publications out of 601 identified and screened. Early studies did not find many health outcomes associated with PBB, possibly because of methodological limitations. More recent studies on long-term and multigenerational impacts found an increased breast cancer risk, accelerated pubertal development and earlier menarche for girls exposed in utero, urogenital problems and slower pubertal development in boys exposed in utero, lower estrone 3-glucuronide and follicle-stimulating hormone among women exposed in childhood, and increased miscarriage risk among daughters of exposed women. Epigenetic and metabolomic research reported altered pathways related to estrogenic effects and immune function, and epigenetic alterations of spermatogenic cells. DISCUSSION: This unique community-academic partnership has produced insights into multigenerational consequences of EDC/POP exposures across the lifecourse. The findings from this cohort underscore the broader relevance of critical windows of vulnerability, particularly during fetal development and childhood.. https://doi.org/10.1289/EHP15012.

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.

OBJECTIVES: To explore how artificial intelligence (AI) can enhance infodemiology, which distributes and scans information in the electronic medium, to process social media posts for HIV pre-exposure prophylaxis (PrEP). DESIGN: Systematic Review. METHODS: We searched in the U.S. Centers for Disease Control and Prevention's Prevention Research Synthesis database through June 2024 (PROSPERO: CRD42023458870). We included infodemiology studies published in English and reported using AI to process social media posts on PrEP. Two reviewers independently screened citations, extracted data, and conducted a risk of bias assessment using the Joanna Briggs Institute Critical Appraisal Checklist for Prevalence Studies. Findings are narratively summarized. RESULTS: Of the 135 citations screened, eight infodemiology studies were identified, analyzing over 58.9 million posts. Infodemiology studies found the PrEP topics commonly discussed in communities (e.g., barriers of uptake), rumors that may raise public health concerns (e.g., PrEP is a prevention method against COVID-19 infection), geographic locations where concerns regarding risk of acquiring HIV were raised (e.g., most HIV-related posts were from the 10 states with the highest numbers of new HIV diagnoses), and predicted HIV trends (e.g., HIV-related tweets were negatively correlated with the county-level HIV incidence rate in the following year). CONCLUSIONS: Despite the limitations of this review including a small number of studies reviewed, our review suggests social media posts may provide information on real-time PrEP-related concerns, and AI can accelerate and enhance the processing of mass data to identify the information that communities need and the areas/locations that may need HIV prevention intervention.

OBJECTIVES: This project aimed to understand the experiences and preferences for social risk factor screening among racially, ethnically, and linguistically diverse cancer survivors in the Washington, DC, region. METHODS: Semi-structured interviews were conducted with English, Spanish, and Amharic-speaking breast and prostate cancer survivors. Data were inductively coded to identify themes, and differences by race and preferred language were evaluated. FINDINGS: Twenty-two interviews in English (n = 14), Spanish (n = 7), and Amharic (n = 1) among participants who identified as Black (n = 8), White (n = 5), Asian (n = 1), Other (n = 6), and multiracial (n = 2) were completed. Participants reported unresolved needs during treatment including transportation, healthful food, mental health care, financial help, and employment assistance. COVID-19 exacerbated many needs. Most participants did not recall discussing needs with oncology teams, but all participants were open to having these conversations. CONCLUSION(S): This research reveals that cancer survivors might benefit from culturally appropriate strategies that address social needs.

BACKGROUND: Population size estimation (PSE) for key populations is needed to inform HIV programming and policy. OBJECTIVE: This study aimed to examine the utility of applying a recently proposed method using Google Trend (GT) internet search data to generate PSE (Google Trends Population Size Estimate [GTPSE]) for men who have sex with men (MSM) in 54 countries in Africa, Asia, the Americas, and Europe. METHODS: We examined GT relative search volumes (representing the relative internet search frequency of specific search terms) for "porn" and, as a comparator term, "gay porn" for the year 2020. We assumed "porn" represents "men" (denominator) while "gay porn" represents a subset of "MSM" (numerator) in each county, resulting in a proportional size estimate for MSM. We multiplied the proportional GTPSE values with the countries' male adult population (15-49 years) to obtain absolute size estimates. Separately, we produced subnational MSM PSE limited to countries' (commercial) capitals. Using linear regression analysis, we examined the effect of countries' levels of urbanization, internet penetration, criminalization of homosexuality, and stigma on national GTPSE results. We conducted a sensitivity analysis in a subset of countries (n=14) examining the effect of alternative English search terms, different language search terms (Spanish, French, and Swahili), and alternative search years (2019 and 2021). RESULTS: One country was excluded from our analysis as no GT data could be obtained. Of the remaining 53 countries, all national GTPSE values exceeded the World Health Organization's recommended minimum PSE threshold of 1% (range 1.2%-7.5%). For 44 out of 49 (89.8%) of the countries, GTPSE results were higher than Joint United Nations Programme on HIV/AIDS (UNAIDS) Key Population Atlas values but largely consistent with the regional UNAIDS Global AIDS Monitoring results. Substantial heterogeneity across same-region countries was evident in GTPSE although smaller than those based on Key Population Atlas data. Subnational GTPSE values were obtained in 51 out of 53 (96%) countries; all subnational GTPSE values exceeded 1% but often did not match or exceed the corresponding countries' national estimates. None of the covariates examined had a substantial effect on the GTPSE values (R2 values 0.01-0.28). Alternative (English) search terms in 12 out of 14 (85%) countries produced GTPSE>1%. Using non-English language terms often produced markedly lower same-country GTPSE values compared with English with 10 out of 14 (71%) countries showing national GTPSE exceeding 1%. GTPSE used search data from 2019 and 2021, yielding results similar to those of the reference year 2020. Due to a lack of absolute search volume data, credibility intervals could not be computed. The validity of key assumptions, especially who (males and females) searches for porn and gay porn, could not be assessed. CONCLUSIONS: GTPSE for MSM provides a simple, fast, essentially cost-free method. Limitations that impact the certainty of our estimates include a lack of validation of key assumptions and an inability to assign credibility intervals. GTPSE for MSM may provide an additional data source, especially for estimating national-level PSE.

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.

Households are a significant source of SARS-CoV-2 transmission, even during periods of low community-level spread. Comparing household transmission rates by SARS-CoV-2 variant may provide relevant information about current risks and prevention strategies. This investigation aimed to estimate differences in household transmission risk comparing the SARS-CoV-2 Delta and Omicron variants using data from contact tracing and interviews conducted from November 2021 through February 2022 in five U.S. public health jurisdictions (City of Chicago, Illinois; State of Connecticut; City of Milwaukee, Wisconsin; State of Maryland; and State of Utah). Generalized estimating equations were used to estimate attack rates and relative risks for index case and household contact characteristics. Data from 848 households, including 2,622 individuals (median household size = 3), were analyzed. Overall transmission risk was similar in households with Omicron (attack rate = 47.0%) compared to Delta variant (attack rate = 48.0%) circulation. In the multivariable model, a pattern of increased transmission risk was observed with increased time since a household contact's last COVID-19 vaccine dose in Delta households, although confidence intervals overlapped (0-3 months relative risk = 0.8, confidence interval: 0.5-1.2; 4-7 months relative risk = 1.3, 0.9-1.8; ≥8 months relative risk = 1.2, 0.7-1.8); no pattern was observed in Omicron households. Risk for household contacts of symptomatic index cases was twice that of household contacts of asymptomatic index cases (relative risk = 2.0, 95% confidence interval: 1.4-2.9), emphasizing the importance of symptom status, regardless of variant. Uniquely, this study adjusted risk estimates for several index case and household contact characteristics and demonstrates that few characteristics strongly dictate risk, likely reflecting the complexity of the biological and social factors which combine to impact SARS-CoV-2 transmission.

Workers in electronics waste and lamp recycling facilities are at risk of exposure to elemental mercury through inhalation of mercury vapor and mercury-containing dust. Employers at an electronics waste and lamp recycling facility in Ohio that crushes mercury-containing lamps expressed concerns about mercury exposure from work processes and requested a health hazard evaluation by CDC's National Institute for Occupational Safety and Health (NIOSH). In April 2023, NIOSH conducted a multidisciplinary investigation to assess elemental and inorganic mercury exposures, including epidemiologic, environmental, and ventilation assessments. Results indicated that mercury vapor was detected throughout the facility, with six of 14 workers having elevated urine mercury levels. These workers had a median job tenure of 8 months; four did not speak English, and five reported symptoms consistent with mercury toxicity, such as metallic or bitter taste, difficulty thinking, and changes in personality. Recommendations included improving the ventilation system, changing work practices to reduce mercury exposure, and providing training and communication tailored to the worker. As the electronic waste recycling industry continues to grow, it is important for employers to evaluate mercury exposure and safeguard employees using a hierarchy of controls. Health departments should consider monitoring occupational mercury exposure in recycling facilities, and clinicians should be aware of the potential for mercury toxicity among workers in these settings.

Shifts in colorectal cancer (CRC) screening, including guidance from the United States Preventive Services Task Force lowering the recommended screening age from 50 to 45 years in 2021, may leave gaps in clinicians' understanding of related barriers and beliefs held by patients. This study uses the National Institute on Minority Health and Health Disparities Research Framework to analyze factors influencing CRC screening uptake among individuals aged 44-54 years and identifies how gaps in knowledge intersect with screening barriers, particularly as they relate to the health care system and sociocultural environment. In 2022, the Centers for Disease Control and Prevention's Division of Cancer Prevention and Control's Screen for Life campaign conducted 12 online focus groups to gather audience insights and test materials. Researchers conducted the focus groups in English and Spanish with individuals aged 44-54 years who had never had CRC and had never received a CRC screening. Focus groups gauged participants' knowledge, awareness, and behavior pertaining to CRC and CRC screening. Results show that participants often lacked knowledge about risk factors and screening modalities and appreciated emotionally resonant communication approaches that addressed gaps in knowledge using demystifying, destigmatizing language and representative imagery. Findings also indicate a need to help patients overcome barriers related to insurance coverage, treatment options, and discrimination. Results may guide the development of future health promotion efforts and empower health care providers to approach conversations with their patients with additional context regarding patients' needs.

BACKGROUND: There is evidence of rapidly growing resistance to antibiotics across Africa. We aimed to establish whether blood culture and sensitivity (BCS) testing is a feasible component of the response to antimicrobial resistance (AMR) in large Kenyan hospitals. METHODS: We used a qualitative study design and conducted key informant interviews (KIIs) using iteratively developed, semi-structured interviews with purposively sampled health-care workers (HCWs) within a network of facilities in Kenya called the Clinical Information Network. Only hospital laboratories that either reported fewer than 50 BCS tests in the previous 6 months or had not recorded use of BCS tests for the past 6 months were included in this study. This selection was further limited by considerations of timing, logistics, and data saturation. Our purposive selection of interviewees was guided by the level of expertise, profession, the number of key informants per hospital, and existing relations with the hospital staff. Each interview took an average of 45 min. Our thematic analysis used inductive coding to identify key themes, and we used causal loop diagrams (CLDs) to explain interactions between themes. The CLDs illustrate how health system issues relate to each other and influence the use of BCS testing in these study settings. FINDINGS: We conducted 72 KIIs across eight tertiary-level Kenyan hospitals between Oct 27 and Dec 2, 2021. Of the 72 HCWs interviewed, 33 (46%) were women and 39 (54%) were men. The participants consisted of 24 clinicians, 26 laboratory staff, and 22 pharmacists with a median age of 36 years (IQR 31-40). We found that the main issues that led to insufficient use of BCS testing in these hospitals related to demand and supply. A host of issues influence clinician demand for BCS testing, including: the use and uptake of BCS, normalisation of clinical diagnosis, unaffordability of the BCS test, turnaround time of the BCS test, preferential use of alternative biochemistry and haematology tests by clinicians, diagnosis by malaria confirmation, and negative results discouraging clinicians from ordering this test. Similarly, health system logistics or supply issues, including laboratory capacity, support and goodwill from hospital management, and scarcity of refresher training opportunities, hinder the availability and sustenance of BCS testing. The CLDs show that these multiple factors can create mutually reinforcing feedback loops that undermine efforts to provide BCS testing in hospitals. INTERPRETATION: The findings suggest that sustainable and routine provision of BCS testing would require many issues to be targeted simultaneously and continuously at the health system level, which is unlikely to be feasible in the short term for Kenyan hospitals. Therefore, in these settings, alternatives to routine BCS testing-such as the adoption of a targeted or vertical approach and the use of survey-informed antimicrobial stewardship to inform local treatment guidelines-should be considered for the control of AMR.

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.

Beyond its physical health impact, the COVID-19 pandemic also resulted in grief from loss of loved ones, isolation due to social distancing, stress, fear, and economic distress-all of which impacted mental health. How Right Now/Qué Hacer Ahora (HRN) is an award-winning, national campaign that provides emotional support to people disproportionately affected by COVID-19. We conducted a theory-based, culturally responsive evaluation to assess the campaign's effect on coping behaviors and resiliency between summer 2020 and spring 2021. We surveyed HRN's priority audiences (older adults/caregivers and those with preexisting health conditions, experiencing violence, or economic distress) in English and Spanish using NORC's national probability panel, AmeriSpeak, over three waves. We also analyzed social media data and monitored HRN website traffic and triangulated these data to understand the campaign's full impact. Campaign exposure was associated with people who were experiencing higher levels of stress and were more likely to seek information to support their emotional well-being. Campaign exposure was also positively associated with increased feelings of resilience and confidence in using coping strategies, especially for people experiencing violence or economic distress and people from racial and ethnic groups. Findings demonstrate the campaign's success in reaching its intended audiences with the mental health support they needed. Additionally, the HRN evaluation's design illustrates how the use of multiple data sources can elucidate a deeper understanding of campaign impact. Findings underscore that culturally responsive health communication interventions-like HRN-can provide needed mental health support and resources to disproportionately affected communities.

BACKGROUND: The COVID-19 pandemic has generated a demand for timely data, resulting in a surge of mobile phone surveys for tracking the impacts of and responses to the pandemic. Mobile phone surveys have become a preferred mode of data collection across low- and middle-income countries. OBJECTIVE: This study piloted 2 population-based, cross-sectional mobile phone surveys among Sri Lankan residents in 2020 and 2021 during the COVID-19 pandemic. The surveys aimed to gather data on knowledge, attitudes, and practices, vaccine acceptability, availability, and barriers to COVID-19 testing, and use of a medicine distribution service. METHODS: The study used Surveda, an open-source survey tool developed by the NCD (noncommunicable disease) Mobile Phone Survey Data 4 Health Initiative, for data collection and management. The surveys were conducted through interactive voice response using automated, prerecorded messages in Sinhala, Tamil, and English. The sample design involved random sampling of mobile phone numbers, stratified by sex, proportional to the general population. Eligibility criteria varied between surveys, targeting adults aged 35 years and older with any noncommunicable disease for the first survey and all adults for the second survey. The data were adjusted to population estimates, and statistical analysis was conducted using SAS (SAS Institute) and R software (R Core Team). Descriptive statistics, Rao-Scott chi-square tests, and z tests were used to analyze the data. Response rates, cooperation rates, and productivity of the sampling approach were calculated. RESULTS: In the first survey, n=5001, the overall response rate was 7.5%, with a completion rate of 85.6%. In the second survey, n=1250, the overall response rate was 10.9%, with a completion rate of 61.9%. Approximately 3 out of 4 adults reported that they avoided public places (888/1175, 75.6%), more than two-thirds avoided public transportation (808/1173, 68.9%), and 9 out of 10 practiced physical distancing (1046/1167, 89.7%). Approximately 1 out of 10 Sri Lankan persons reported being tested for COVID-19, and the majority of those received a polymerase chain reaction test (112/161, 70%). Significantly more males than females reported being tested for COVID-19 (98/554, 17.8% vs 61/578, 10.6%, respectively; P<.001). Finally, the majority of adult Sri Lankan people reported that they definitely or probably would get the COVID-19 vaccination (781/1190, 65.7%). CONCLUSIONS: The surveys revealed that, overall, the adult Sri Lankan population adhered to COVID-19 mitigation strategies. These findings underscore the use of mobile phone surveys in swiftly and easily providing essential data to inform a country's response during the COVID-19 pandemic, obviating the need for face-to-face data collection.

Laboratory-based surveillance for enteric pathogens causing diarrhea is foundational for monitoring foodborne diseases in the United States. However, diarrheal illnesses are not always confirmed by laboratory testing, so estimates of the true number of illnesses must adjust for underdiagnosis, including underdiagnosis due to ill persons not seeking medical care or submitting a stool sample for laboratory testing. We assessed these factors among persons with an acute diarrheal illness who responded to the most recent Foodborne Diseases Active Surveillance Network (FoodNet) Population Survey (2018-2019). Multiple modes of administration (telephone, web-based) and multiple sampling frames were used to ask survey respondents in English or Spanish about diarrhea and other symptoms experienced in the 30 days before the interview and to ask if they had sought medical care or submitted a stool sample. Of 1018 respondents with an acute diarrheal illness, 22.0% had sought medical care and 4.7% submitted a stool sample. On multivariable analysis, older adults (aged 65 years and over), male respondents, and persons with a household income of ≥$40,000 per annum were significantly more likely to seek medical care, as were respondents reporting cough, fever, vomiting, recent international travel, or duration of diarrhea for ≥3 days. Older adults and persons with five or more loose stools in 24 h who sought medical care were significantly more likely to submit a stool sample. Ill respondents with a concurrent cough were less likely to submit a stool sample. Sociodemographic characteristics, symptoms, and international travel influence whether a patient with an acute diarrheal illness will seek care or submit a stool specimen. Accounting for these factors when analyzing surveillance data will likely produce more precise estimates of the true number of foodborne illnesses.

AIM: Among people with diabetes those with chronic kidney disease (CKD) have a reduced life expectancy with increased risk of cardiovascular disease (CVD) a major contributor to morbidity and mortality. CKD related to diabetes is growing worldwide and is one of the leading causes of kidney failure globally. Diabetes is associated with accelerated vascular ageing and the related mechanisms and mediators that drive the progression of CKD and CVD disease in people with diabetes may help provide insights into the pathophysiology of cardio-renal complications and guide treatment interventions in people with diabetes. METHODS: We conducted a narrative review of the literature using PubMed for English language articles that contained keywords that related to diabetes, chronic or diabetic kidney disease, ageing, cellular senescence, arterial stiffness, Klotho and sirtuins, sodium-glucose co-transporter-2 (SGLT-2) inhibitors, renin angiotensin aldosterone system (RAAS) and glucagon-like peptide-1 (GLP-1) receptor agonists. RESULTS: Progressive kidney disease in diabetes is associated with accelerated ageing driven in part by multiple processes such as cellular senescence, inflammation, oxidative stress and circulating uremic toxins. This accelerated ageing phenotype contributes to increased arterial stiffness, endothelial dysfunction, cognitive decline and muscle wasting, thereby elevating morbidity and mortality in individuals with diabetes and CKD. Deficiency of the kidney-derived anti-ageing hormone Klotho and reduced sirtuin levels play pivotal roles in these ageing pathways. Dietary, lifestyle and pharmacological interventions targeting vascular ageing may help reduce the progression of CKD and associated CVD in people with diabetes. The current standard of care and pillars of treatment for kidney disease such as RAAS inhibitors, SGLT-2 inhibitors and GLP-1 receptor agonists all influence pathways involved in vascular ageing. CONCLUSIONS: A multifactorial intervention to prevent the development of CKD by targeting traditional risk factors as well as treatment with novel agents with cardio-renal beneficial effects can prevent accelerated ageing and extend lifespan in people with diabetes.

Wastewater testing can inform public health action as a component of polio outbreak response. During 2022-2023, a total of 7 US jurisdictions (5 states and 2 cities) participated in prospective or retrospective testing of wastewater for poliovirus after a paralytic polio case was identified in New York state. Two distinct vaccine-derived poliovirus type 2 viruses were detected in wastewater from New York state and New York City during 2022, representing 2 separate importation events. Of those viruses, 1 resulted in persistent community transmission in multiple New York counties and 1 paralytic case. No poliovirus was detected in the other participating jurisdictions (Connecticut, New Jersey, Michigan, and Illinois and Chicago, IL). The value of routine wastewater surveillance for poliovirus apart from an outbreak is unclear. However, these results highlight the ongoing risk for poliovirus importations into the United States and the need to identify undervaccinated communities and increase vaccination coverage to prevent paralytic polio.

Organophosphate insecticides are widely used for adult mosquito control. Although proven effective in reducing mosquito populations and limiting arbovirus transmission, public concern exists regarding potential human health effects associated with organophosphate exposure. The aim of this scoping review was to describe any reported human health conditions associated with organophosphates during their use for adult mosquito control in the United States and Canada. Original peer-reviewed articles published in English language journals from 1 January 2000 to 22 May 2024, were obtained by searching from the databases MEDLINE, EMBASE, Agricultural & Environmental Science Collection, CAB Abstracts, and Scopus. The search identified 6,154 screened articles. Following an independent review, 10 studies were identified that described human health conditions associated with organophosphate exposure during adult mosquito control applications. Of the 10 included studies, only two articles were published within the last 11 years (2013 to 22 May 2024). Three types of study design were represented in the included studies: cohort (n = 5), case study (n = 1), and risk assessment (n = 4). The included studies could not determine causality between exposure to adulticides and development of illness or adverse impacts. Exposure to organophosphates did not contribute to an observed increase in metabolic toxicity, hospitalization rates, or self-reported symptoms and exposure. The available and limited evidence indicates that organophosphates can be used safely to control nuisance mosquitoes or mosquitoes that transmit arboviruses. Continued research regarding the human health effects associated with organophosphate applications for adult mosquito control could help evaluate the basis of the public's concerns and inform public health decision-making.

CONTEXT: Lead exposures among school-age children are a major public health issue. Although the harmful effects of lead exposure during the first years of life are well known, there is not as much understanding of the effects of low levels of lead exposure during later childhood. OBJECTIVES: To review the effects of blood lead levels (BLLs) <10 µg/dL in school-age children and adolescents. DATA SOURCES: We searched Medline, Embase, Global health, CINAHL, Scopus, and Environmental Science Collection databases between January 1, 2000, and May 11, 2023. STUDY SELECTION: We included peer-reviewed English-language articles that presented data on the effects of BLLs <10 µg/dL in individuals ages 5 through 18 years. DATA EXTRACTION: Data on country, population, analytic design, sample size, age, BLLs, outcomes, covariates, and results were extracted. RESULTS: Overall, 115 of 3180 screened articles met the inclusion criteria. The reported mean or median BLL was <5 µg/dL in 98 articles (85%). Of the included articles, 89 (77%) presented some evidence of an association between BLLs <10 µg/dL during school age and detrimental outcomes in a wide range of categories. The strongest evidence of an association was for the outcomes of intelligence quotient and attention-deficit/hyperactivity disorder diagnoses or behaviors. LIMITATIONS: Few articles controlled for BLLs at age <5 years, limiting conclusions about the relation between later BLLs and outcomes. CONCLUSIONS: BLLs <10 µg/dL in school-age children and adolescents may be associated with negative outcomes. This review highlights areas that could benefit from additional investigation.

BACKGROUND: The field of healthcare epidemiology is increasingly focused on identifying, characterizing, and addressing social determinants of health (SDOH) to address inequities in healthcare quality. To identify evidence gaps, we examined recent systematic reviews examining the association of race, ethnicity, and SDOH with inpatient quality measures. METHODS: We searched Medline via OVID for English language systematic reviews from 2010 to 2022 addressing race, ethnicity, or SDOH domains and inpatient quality measures in adults using specific topic questions. We imported all citations to Covidence (www.covidence.org, Veritas Health Innovation) and removed duplicates. Two blinded reviewers assessed all articles for inclusion in 2 phases: title/abstract, then full-text review. Discrepancies were resolved by a third reviewer. RESULTS: Of 472 systematic reviews identified, 39 were included. Of these, 23 examined all-cause mortality; 6 examined 30-day readmission rates; 4 examined length of stay, 4 examined falls, 2 examined surgical site infections (SSIs) and one review examined risk of venous thromboembolism. The most evaluated SDOH measures were sex (n = 9), income and/or employment status (n = 9), age (n = 6), race and ethnicity (n = 6), and education (n = 5). No systematic reviews assessed medication use errors or healthcare-associated infections. We found very limited assessment of other SDOH measures such as economic stability, neighborhood, and health system access. CONCLUSION: A limited number of systematic reviews have examined the association of race, ethnicity and SDOH measures with inpatient quality measures, and existing reviews highlight wide variability in reporting. Future systematic evaluations of SDOH measures are needed to better understand the relationships with inpatient quality measures.

Objectives. To compare the incidence, case-hospitalization rates, and vaccination rates of COVID-19 between people experiencing sheltered homelessness (PESH) and the broader community in Chicago, Illinois, and describe the impact of a whole community approach to disease mitigation during the public health emergency. Methods. Incidence of COVID-19 among PESH was compared with community-wide incidence using case-based surveillance data from March 1, 2020, to May 11, 2023. Seven-day rolling means of COVID-19 incidence were assessed for the overall study period and for each of 6 distinct waves of COVID-19 transmission. Results. A total of 774 009 cases of COVID-19 were detected: 2579 among PESH and 771 430 in the broader community. Incidence and hospitalization rates per 100 000 in PESH were more than 5 times higher (99.84 vs 13.94 and 16.88 vs 2.14) than the community at large in wave 1 (March 1, 2020-October 3, 2020). This difference decreased through wave 3 (March 7, 2021-June 26, 2021), with PESH having a lower incidence rate per 100 000 than the wider community (8.02 vs 13.03). Incidence and hospitalization of PESH rose again to rates higher than the broader community in waves 4 through 6 but never returned to wave 1 levels. Throughout the study period, COVID-19 incidence among PESH was 2.88 times higher than that of the community (70.90 vs 24.65), and hospitalization was 4.56 times higher among PESH (7.51 vs 1.65). Conclusions. Our findings suggest that whole-community approaches can minimize disparities in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission between vulnerable populations and the broader community, and reinforce the benefits of a shared approach that include multiple partners when addressing public health emergencies in special populations.

Background: The first licensed malaria vaccine, RTS,S/AS01<inf>E</inf>, confers moderate protection against symptomatic disease. Because many malaria infections are asymptomatic, we conducted a large-scale longitudinal parasite genotyping study of samples from a clinical trial exploring how vaccine dosing regimen affects vaccine efficacy. Method(s): Between Sept 28, 2017, and Sept 25, 2018, 1500 children aged 5-17 months were randomly assigned (1:1:1:1:1) to receive four different RTS,S/AS01<inf>E</inf> regimens or a rabies control vaccine in a phase 2b open-label clinical trial in Ghana and Kenya. Participants in the four RTS,S groups received two full doses at month 0 and month 1 and either full doses at month 2 and month 20 (group R012-20); full doses at month 2, month 14, month 26, and month 38 (group R012-14); fractional doses at month 2, month 14, month 26, and month 38 (group Fx012-14; early fourth dose); or fractional doses at month 7, month 20, and month 32 (group Fx017-20; delayed third dose). We evaluated the time to the first new genotypically detected infection and the total number of new infections during two follow-up periods (12 months and 20 months) in more than 36 000 dried blood spot specimens from 1500 participants. To study vaccine effects on time to the first new infection, we defined vaccine efficacy as one minus the hazard ratio (HR; RTS,S vs control) of the first new infection. We performed a post-hoc analysis of vaccine efficacy based on malaria infection status at first vaccination and force of infection by month 2. This trial (MAL-095) is registered with ClinicalTrials.gov, NCT03281291. Finding(s): We observed significant and similar vaccine efficacy (25-43%; 95% CI union 9-53) against first new infection for all four RTS,S/AS01<inf>E</inf> regimens across both follow-up periods (12 months and 20 months). Each RTS,S/AS01<inf>E</inf> regimen significantly reduced the mean number of new infections in the 20-month follow-up period by 1.1-1.6 infections (95% CI union 0.6-2.1). Vaccine efficacy against first new infection was significantly higher in participants who were infected with malaria (68%; 95% CI 50-80) than in those who were uninfected (37%; 23-48) at the first vaccination (p=0.0053). Interpretation(s): All tested dosing regimens blocked some infections to a similar degree. Improved vaccine efficacy in participants infected during vaccination could suggest new strategies for highly efficacious malaria vaccine development and implementation.

Tens of thousands of trucks cross the U.S.-Mexico border every day. Cross-border truckers' high mobility puts them at risk of acquiring and transmitting infectious diseases and creates challenges reaching them with emergency public health messaging due to their everchanging locations and limited English proficiency. Despite this community-level transmission risk and documented health disparities related to various infectious and noninfectious diseases experienced by truckers themselves, little has been published to provide practical recommendations on better reaching this audience through innovative outreach methods. This article describes a COVID-19 health promotion campaign that aimed to (1) identify, pilot test, and evaluate effective messages, channels, sources, and settings for reaching truckers on both sides of the U.S.-Mexico border and (2) build capacity and sustainability for messaging around future health emergencies. The pilot program ran for 6 weeks, June to August 2023, in three key commercial border crossings and delivered approximately 50,000,000 impressions, nearly 45% more impressions than expected. Considerations for practitioners include the areas of design, implementation, and evaluation. The results provide insight into how to design health promotion messages that resonate with cross-border truckers and how to place these messages where they will be seen, heard, and understood. This includes working effectively with community health workers (CHW), known locally as promotores; identifying local partners that allow CHW to set up onsite; and, working with partner organizations including employers. Practical insights for building evaluation metrics into traditional and grassroots outreach strategies to facilitate real-time optimization as well as continued learning across efforts are also described.

INTRODUCTION: There is no licensed vaccine against gonorrhea but Neisseria meningitidis serogroup B outer membrane vesicle-based vaccines, like MenB-4C, may offer cross-protection against gonorrhea. This systematic review and meta-analysis synthesized the published literature on MenB-4C vaccine effectiveness against gonorrhea. METHODS: We conducted a literature search of electronic databases (PubMed, Medline, Embase, Global Health, Scopus, Google Scholar, CINAHL, and Cochrane Library) to identify peer-reviewed papers, published in English, from 1/1/2013-7/12/2024 that reported MenB-4C vaccine effectiveness estimates against gonorrhea and gonorrhea/chlamydia co-infection, and the duration of MenB-4C vaccine-induced protection. We estimated pooled MenB-4C vaccine effectiveness (≥1 dose) against gonorrhea using the DerSimonian-Laird random effects model. RESULTS: Eight papers met our eligibility criteria. Receipt of ≥1 dose of MenB-4C vaccine was 23%-47% effective against gonorrhea. Two doses of MenB-4C vaccine were 33-40% effective against gonorrhea and one dose of MenB-4C vaccine was 26% effective. MenB-4C vaccine effectiveness against gonorrhea/chlamydia co-infection was mixed with two studies reporting effectiveness estimates of 32% and 44%, and two other studies showing no protective effect. MenB-4C vaccine effectiveness against gonorrhea was comparable in people living with HIV (44%) and people not living with HIV (23%-47%). Pooled MenB-4C vaccine effectiveness (≥1 dose) against gonorrhea was 32.4%. One study concluded that MenB-4C vaccine effectiveness against gonorrhea may wane approximately 36 months post-vaccination. CONCLUSION: MenB-4C vaccine is moderately effective against gonorrhea in various populations. Prospective clinical trials that assess the efficacy of MenB-4C against gonorrhea, gonorrhea/chlamydia co-infection, and duration of protection are warranted to strengthen this evidence.

Introduction: Ethiopia introduced a second dose of measles-containing vaccine (MCV2) in 2019 to provide further protection against measles and further progress toward elimination. However, the sub-optimal coverage of both MCV1 and MCV2 suggest challenges with vaccine uptake. In this qualitative study, we explored barriers to the uptake of MCV2 among caregivers, community leaders, and healthcare workers (HCWs). Method: A qualitative study was conducted between mid-April and mid-May 2021. We selected ten woredas (districts) in the Oromia Region, Ethiopia, stratified by settlement type (urban/rural), MCV1 coverage (high ≥ 80%; low < 80%), and history of measles outbreaks between June 2019 and June 2020. Experiences surrounding barriers to MCV2 uptake were discussed via focus group discussions (FGDs) and in-depth interviews (IDIs) with caregivers of children 12-23 and 24-36 months and key informant interviews (KIIs) with HCWs who administer vaccines and with community leaders. Participants were recruited via snowball sampling. Recorded data were transcribed, translated to English, and analyzed using ATLAS.ti v.09. Results: Forty FGDs and 60 IDIs with caregivers, 60 IDIs with HCWs, and 30 KIIs with community leaders were conducted. Barriers among caregivers included lack of knowledge and awareness about MCV2 and the vaccination schedule, competing priorities, long wait times at health facilities, vaccine unavailability, negative interactions with HCWs, and transportation challenges. At the community level, trusted leaders felt they lacked adequate knowledge about MCV2 to address caretakers' questions and community misconceptions. HCWs felt additional training on MCV2 would prepare them to better respond to caretakers' concerns. Health system barriers identified included the lack of human, material, and financial resources to deliver vaccines and provide immunization outreach services, which caretakers reported as their preferred way of accessing immunization. Conclusions: Barriers to MCV2 uptake occur at multiple levels of immunization service delivery. Strategies to address these barriers include tools to help caretakers track appointments, enhanced community engagement, HCW training to improve provider-client interactions and MCV2 knowledge, and efforts to manage HCW workload.

Persistent organic pollutants may negatively impact cognition; however, associations between persistent organic pollutants and changes in cognition among United States Hispanic/Latino adults have not been investigated. Herein, we examined the associations between 33 persistent organic pollutants and cognitive changes among 1837 Hispanic/Latino adults. At baseline (2008-2011; Visit 1), participants provided biospecimens in which we measured levels of 5 persistent pesticides or pesticide metabolites, 4 polybrominated diphenyl ethers and 2,2',4,4',5,5'-hexabromobiphenyl, and 24 polychlorinated biphenyls. At Visit 1 and again at Visit 2 (2015-2018), a battery of neurocognitive tests was administered which included the Brief-Spanish English Verbal Learning Test, Word Fluency Test, and Digit Symbol Substitution Test. To estimate the adjusted associations between changes in cognition and each POP, we used linear regression for survey data. Each doubling in plasma levels of polychlorinated biphenyls 146, 178, 194, 199/206, and 209 was associated with steeper declines in global cognition (βs range:-0.053 to -0.061) with stronger associations for the Brief-Spanish English Verbal Learning Test. Persistent organic pollutants, in particular polychlorinated biphenyls, were associated with declines in cognition over 7 years and may be a concern for Hispanic/Latino adults.

INTRODUCTION: This paper examined the economic evidence of patient navigation services to increase breast and cervical cancer screenings among historically disadvantaged racial and ethnic populations and people with lower incomes. METHODS: The literature search strategy for this systematic review included English-language studies conducted in high-income countries that were published from database inception to December 2022. Studies on patients with existing cancer or without healthcare system involvement were excluded. Analysis was completed in January 2023. All monetary values reported are in 2022 U.S. dollars. RESULTS: The search yielded 3 breast cancer, 2 cervical cancer, and 2 multiple cancer studies that combined breast and cervical cancer with other cancer screenings. For breast cancer screening, the intervention cost per patient ranged from $109 to $10,245. Two studies reported $154 and $740 as intervention cost per additional person screened. Changes in healthcare cost per person from 2 studies were $202 and $2,437. Two studies reported cost per quality-adjusted life year (QALY) gained of $3,852 and $39,159 while one study reported cost per life year (LY) gained of $22,889. For cervical cancer, two studies reported intervention cost per person ($103 and $794) and per additional person screened ($56 and $533) with one study reporting a cost per QALY gained ($924). DISCUSSION: All estimates of cost per QALY/LY saved for breast cancer screening were below a conservative threshold of $50,000 indicating that patient navigation services for breast cancer screening were cost-effective. There is limited evidence to determine cost-effectiveness of patient navigation services for cervical cancer screening.

OBJECTIVE: To describe the prevalence, characteristics, and health-related outcomes of children with diagnosed health conditions and functional difficulties who do not meet criteria for having a special health care need based on the traditional scoring of the Children with Special Health Care Needs (CSHCN) Screener. METHODS: Data come from the 2016 to 2021 National Survey of Children's Health (n = 225 443). Child characteristics and health-related outcomes were compared among 4 mutually exclusive groups defined by CSHCN Screener criteria and the presence of both conditions and difficulties. RESULTS: Among children who do not qualify as children and youth with special health care needs (CYSHCN) on the CSHCN Screener, 6.8% had ≥1 condition and ≥1 difficulty. These children were more likely than CYSHCN to be younger, female, Hispanic, uninsured, privately insured, living in a household with low educational attainment, have families with more children and a primary household language other than English. After adjustment, non-CYSHCN with ≥1 conditions and ≥1 difficulty were less likely than CYSHCN, but significantly more likely than other non-CYSHCN, to have ≥2 emergency department visits, have unmet health care needs, not meet flourishing criteria, live in families that experienced child health-related employment impacts and frustration accessing services. Including these children in the calculation of CYSHCN prevalence increases the national estimate from 19.1% to 24.6%. CONCLUSIONS: Approximately 4 million children have both a diagnosed health condition and functional difficulties but are not identified as CYSHCN. An expanded approach to identify CYSHCN may better align program and policy with population needs.

OBJECTIVES: To identify studies promoting the use of artificial intelligence (AI) or automation with HIV pre-exposure prophylaxis (PrEP) care and explore ways for AI to be used in PrEP interventions. DESIGN: Systematic review. METHODS: We searched in the US Centers for Disease Control and Prevention Research Synthesis database through November 2023 PROSPERO (CRD42023458870). We included studies published in English that reported using AI or automation in PrEP interventions. Two reviewers independently reviewed the full text and extracted data by using standard forms. Risk of bias was assessed using either the revised Cochrane risk-of-bias tool for randomized trials for randomized controlled trials or an adapted Newcastle-Ottawa Quality Assessment Scale for non-randomized studies. RESULTS: Our search identified 12 intervention studies (i.e., interventions that used AI/automation to improve PrEP care). Currently available intervention studies showed AI/automation interventions were acceptable and feasible in PrEP care while improving PrEP-related outcomes (i.e., knowledge, uptake, adherence, discussion with care providers). These interventions have used AI/automation to reduce workload (e.g., directly observed therapy) and helped non-HIV specialists prescribe PrEP with AI-generated clinical decision-support. Automated tools can also be developed with limited budget and staff experience. CONCLUSIONS: AI and automation have high potential to improve PrEP care. Despite limitations of included studies (e.g., the small sample sizes and lack of rigorous study design), our review suggests that by using aspects of AI and automation appropriately and wisely, these technologies may accelerate PrEP use and reduce HIV infection.
