AIDS Behav 2025 ![]() Young People Living with HIV (YPLHIV, 15-24 years) are an important demographic of Persons Living with HIV (PLHIV) globally and in Southern Africa. However, YPLHIV experience poor outcomes across the HIV diagnostic and treatment cascade due to multiple factors. We estimated the prevalence and determinants of HIV viral suppression in YPLHIV on antiretroviral therapy (ART) in selected Southern African countries. We used publicly available data from Malawi, Zimbabwe, Mozambique, Lesotho, and Eswatini collected during the Population-based HIV Impact Assessments (PHIAs) of 2020 to 2021. Weighted proportions, and 95% confidence intervals (CI) were computed to estimate the prevalence of viral suppression (< 1000c/ml) and bivariate and multivariate analyses were conducted to identify determinants of viral suppression. A total of 855 records of YPLHIV on ART were included in the analysis. The prevalence of viral suppression in YPLHIV on ART was 82.4% (95% CI: 76.7, 86.9). Residing in Mozambique and duration on ART were inversely associated with viral suppression; adjusted odds ratios (AORs) of 0.37 (95% CI: 0.14, 0.95), and 0.87 (95% CI: 0.80, 0.94), respectively. A negative result in the depression screen, being married/cohabitating, and ever switching an ART regimen were positively associated with viral suppression: AORs of 5.78 (95% CI: 2.21, 15.11), 3.72 (95% CI: 1.44, 9.63), and 3.44 (95% CI: 1.69, 7), respectively. YPLHIV had suboptimal viral suppression lower than the UNAIDS 95% targets and may benefit from further research and tailored interventions addressing modifiable factors associated with viral suppression such as depression. |

Sci Transl Med 2025 17 (788) eads8214 ![]() ![]() Human norovirus causes more than 700 million illnesses annually. Extensive genetic diversity and a paucity of information on conserved neutralizing epitopes pose major obstacles to the design of broadly protective norovirus immunogens. Here, we used high-resolution liquid chromatography-tandem mass spectrometry (LC-MS/MS)-driven proteomics to quantitatively characterize the circulating serum IgG repertoire before and after immunization with an experimental monovalent norovirus GII.4 VP1 capsid-encoding adenoviral vaccine. Two participants were specifically selected on the basis of the breadth of serum neutralization responses either across GII.4 variants (participant A) or across GII genotypes (participant B). In participant A, vaccination back-boosted highly abundant serum antibody clonotypes targeting epitopes conserved among rapidly evolving GII.4 variants spanning from a strain identified in 1987 to a strain identified in 2019. In participant B, we identified a recall response consisting of broadly neutralizing monoclonal antibodies with remarkable cross-GII ligand-binding blockade (blocking ≥ seven GII genotypes) and virus neutralization breadth. The cocrystal structure of one of these antibodies, VX22, in complex with the VP1 capsid protruding (P) domain revealed a highly conserved epitope (residues 479 to 484 and 509 to 513) within two lateral loops of the P1 subdomain. Antibody evolutionary trajectory analysis further revealed that VX22 had originally evolved from an early heterologous infection, likely by a GII.12 strain. Together, our study demonstrates that norovirus human monoclonal antibodies with broad GII.4 potency and cross-GII breadth can be boosted in serum after immunization with an adenoviral vector-based vaccine, findings that may guide the design of immunogens for broadly protective norovirus vaccines. |
Exploring associations of financial well-being with health behaviours and physical and mental health: a cross-sectional study among US adults
Mercado C , Bullard KM , Bolduc MLF , Banks D , Andrews C , Freggens ZRF , Njai R . BMJ Public Health 2024 2 (1) e000720 ![]() BACKGROUND: Health disparities exist across socioeconomic status levels, yet empirical evidence between financial well-being (FWB) and health are limited. METHODS: This cross-sectional study combined data from 25 370 adults aged ≥18 years in the 2019 National Health Interview Survey with estimated household FWB scores from the Consumer Financial Protection Bureau's 2016 National Financial Well-being Survey. FWB associations with health service visits, biometric screenings, smoking status, body mass index and physical and mental conditions were tested using age-adjusted, sex-adjusted and health insurance coverage-adjusted linear regression analysis. RESULTS: In 2019, the mean FWB for US adults was 56.1 (range 14 (worse) to 95 (best)). With increasing time since the last health service visit or screening, FWB was increasingly lower compared with adults with visits or screenings <1 year (≥10 years or 'never', FWB ranged from -1 (blood sugar check) to -6.5 (dental examination/cleaning) points). FWB was lower with declining general health status (excellent (reference), very good (-0.5 points), good (-3.4 points) and fair/poor (-6.6 points)). Adults with physical health conditions had FWB lower than adults without (range -0.4 (high cholesterol) to -4.6 (disability) points). FWB were lower in adults who have ever been diagnosed with anxiety disorder (-1.8 points) or depression (-2 points). Adults managing their anxiety or depression (no/minimal symptoms currently) had greater FWB (anxiety: 3 points and depression: 4.1 points) than those with symptoms. CONCLUSION: Given the observed associations between FWB and health-related measures, it is crucial to consider FWB in primary and secondary health prevention efforts, recognising the relationship between economics, health and wellness. |
Implementing SARS-CoV-2 routine surveillance in antenatal care in Zambia, 2021-2022: best practices and lessons learned
Tembo T , Heilmann E , Kabamba BM , Fwoloshi S , Kalenga K , Chilambe F , Siwinga M , Rutagwera MR , Musunse M , Kangale C , Yingst S , Yadav R , Savory T , Gutman JR , Sikazwe I , Mulenga LB , Moore CB , Hines JZ . BMC Public Health 2025 25 (1) 813 ![]() ![]() BACKGROUND: In Zambia, the true extent of SARS-CoV-2 infections is unknown because initial surveillance focused on patients with symptoms or severe disease. Antenatal sentinel surveillance had not been used to assess infection trends. The ANC COVID-19 surveillance study sought to determine SARS-CoV-2 seroprevalence and COVID-19 vaccine uptake among pregnant women. We provide insight into the study implementation, challenges encountered, best practices, and lessons learned. METHODS: A repeated cross-sectional seroprevalence survey was implemented at 39 health facilities in four districts from September 2021 to September 2022. Pregnant women aged 15-49 years were enrolled at their first antenatal care visits. An electronic questionnaire gathered demographics and other COVID-19 related information from consenting participants. A dried blood sample was collected to detect IgG antibodies using a multiplex bead assay. Seropositive results were categorized as infection, infection and vaccination or infection based on anti-RBD and anti-nucleocapsid test results. Problems and their root causes were identified as they occurred. Practical problem-solving strategies were devised, implemented, and monitored to ensure that goals were accomplished. RESULTS: In the primary analysis, 7% of the 9,221 samples collected from participants were not tested because they were missing. COVID-19 vaccine uptake of 9,111 pregnant women was assessed. Approximately 64% of participants were cumulatively seropositive for SARS-CoV-2 antibodies. Seroprevalence increased from 27.8% in September 2021 to 56.6% in July 2022. We observed an increase in vaccine coverage (0.5-27%) over time. Women aged 40-49 years old, without education and with prior COVID-19 infection were associated with higher vaccine uptake. The Delta variant of COVID-19 and the reallocation of health facilities between two partners delayed surveillance activities and increased the cost of implementation (e.g., the purchase of additional calibration and validation kits and DBS cards). Protocol deviations were attributed to the lack of experience in conducting research but, the district RAs repeatedly trained health facility staff to enhance their research knowledge. CONCLUSIONS: Incorporating SARS-CoV-2 surveillance into routine antenatal care is feasible and potentially sustainable when existing health system infrastructure, human resources, and surveillance systems are leveraged. Yet, careful planning is needed to anticipate implementation challenges and ensure high-quality data collection. |

BMJ Public Health 2024 2 (2) e000501 ![]() OBJECTIVES: Malaria and curable sexually transmitted and reproductive tract infections (STIs/RTIs) are associated with adverse pregnancy outcomes. This study reports the prevalence and risk factors of curable STIs/RTIs, STI/RTI co-infection and STI/RTI and malaria co-infection among HIV-negative pregnant women at their first antenatal care visit in Kenya, Malawi and Tanzania. METHODS: HIV-negative pregnant women of all gravidae (n=4680) were screened for syphilis with point-of-care tests and treated if positive. Separately, women provided blood samples (n=4569) for rapid plasma reagin (RPR) testing; positive cases were confirmation by Treponema pallidum particle agglutination (TPPA). Women also provided dried blood spots for batch testing of malaria by retrospective polymerase chain reaction (PCR (n=4226) methods. A randomly selected subgroup of women provided vaginal swabs for chlamydia, gonorrhoea and trichomoniasis testing by retrospective PCR batch testing (n=1431), and bacterial vaginosis diagnosis by Nugent scoring (n=1402). RESULTS: Malaria prevalence was 14.6% (95% CI 13.6 to 15.7), 45.9% (43.4 to 48.4) of women were positive for at least one curable STI/RTI and 6.7% (5.5 to 8.1) were co-infected with malaria and a curable STI/RTI. Prevalence of individual STIs/RTIs ranged from 28.5% (26.2 to 30.9) for bacterial vaginosis to 14.5% (12.7 to 16.4) for trichomoniasis, 13.8% (12.1 to 15.7) for chlamydia, 2.7% (1.9 to 3.6) for gonorrhoea and 1.7% (1.4 to 2.2) for RPR/TPPA-confirmed syphilis. The prevalence of STI/RTI co-infection was 10.1% (8.7 to 11.8). Paucigravidae, at highest risk of malaria, were also at greater risk of having chlamydia, gonorrhoea and bacterial vaginosis than multigravidae. CONCLUSIONS: Of women infected with malaria, 49.0% also had a curable STI/RTI and one in five women with at least one STI/RTI were co-infected with more than one STI/RTI. Current antenatal interventions that address malaria and curable STIs/RTIs remain suboptimal. New approaches to preventing and managing these infections in pregnancy are urgently needed.

Effect of prior influenza a(H1N1)pdm09 virus infection on pathogenesis and transmission of human influenza A(H5N1) clade 2.3.4.4b virus in ferret model
Sun X , Belser JA , Li ZN , Brock N , Pulit-Penaloza JA , Kieran TJ , Pappas C , Zeng H , Chang JC , Carney PJ , Bradley-Ferrell BL , Stevens J , Tumpey TM , Levine MZ , Maines TR . Emerg Infect Dis 2025 31 (3) 458-466 ![]() ![]() Reports of human infections with influenza A(H5N1) clade 2.3.4.4b viruses associated with outbreaks in dairy cows in the United States underscore the need to assess the potential cross-protection conferred by existing influenza immunity. We serologically evaluated ferrets previously infected with an influenza A(H1N1)pdm09 virus for cross-reactive antibodies and then challenged 3 months later with either highly pathogenic H5N1 clade 2.3.4.4b or low pathogenicity H7N9 virus. Our results showed that prior influenza A(H1N1)pdm09 virus infection more effectively reduced the replication and transmission of the H5N1 virus than did the H7N9 virus, a finding supported by the presence of group 1 hemagglutinin stalk and N1 neuraminidase antibodies in preimmune ferrets. Our findings suggest that prior influenza A(H1N1)pdm09 virus infection may confer some level of protection against influenza A(H5N1) clade 2.3.4.4.b virus. |
Diabetes distress among US adults with diagnosed diabetes, 2021
Alexander DS , Saelee R , Rodriguez B , Koyama AK , Cheng YJ , Tang S , Rutkowski RE , Bullard KM . Prev Chronic Dis 2025 22 E07 National prevalence of diabetes distress is unknown among US adults. This cross-sectional study examined the prevalence among US adults with diabetes using 2021 National Health Interview Survey data. Multivariable multinomial logistic regressions were used to estimate adjusted prevalence and prevalence ratios for diabetes distress. Adjusted prevalence of moderate and severe diabetes distress was 24.3% (95% CI, 22.5%-26.1%) and 6.6% (95% CI, 5.6%-7.8%), respectively. Prevalence was higher among people aged 18 to 64 years, women, and those with lower incomes. Findings highlight the importance of examining economic and social factors and integrating diabetes distress screening into diabetes management and services. |
Head injury and amyotrophic lateral sclerosis: Population-based study from the National ALS Registry
Raymond J , Howard IM , Berry J , Larson T , Horton DK , Mehta P . Brain Sci 2025 15 (2) Background/Objectives: To examine if head injury (HI) is associated with age at ALS diagnosis in the United States. Methods: In this cross-sectional populationf-based analysis, we identified patients with ALS who were registered from 2015 to 2023 who completed the Registry's head trauma survey module. The association between HI and age at ALS diagnosis was assessed using multivariate analysis. Results: Of the 3424 respondents, 56.6% had experienced a HI. The adjusted odds ratio (aOR) for an ALS diagnosis before age 60 years for patients with a HI was 1.24 (95% CI, 1.07-1.45). One or two HIs had an aOR of 1.15 (95% CI, 0.97-1.36), and five or more HIs had an aOR of 1.58 (95% CI, 1.19-2.09). HI before age 18 years yielded an aOR of 2.03 (95% CI, 1.53-2.70) as well as HI between the ages of 18 and 30 years (aOR = 1.48, 95% CI: 1.06-2.06)). When narrowing the analysis to patients with HI before age 18 compared with patients with no HI, we found an association with HI that led to an emergency department or hospital visit (aOR = 1.50 (95% CI: 1.21-1.86)). Conclusions: In this cross-sectional analysis of ALS patients, HIs occurring in childhood and early adulthood and the number of HIs increased the odds of being diagnosed before age 60 years. These results suggest that HI continues to be a risk factor for ALS and could be associated with a younger age of diagnosis. |
Characterising people who inject drugs, and association with HIV infection: A situation analysis in Kampala City, Uganda
Mudiope P , Mathers B , Nangendo J , Mutyaba S , Mutamba BB , Alamo S , Nanyenya N , Makumbi F , Laker-Oketta M , Wanyenze R . PLOS Glob Public Health 2025 5 (2) e0003370 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. |
Incidence of metabolic and bariatric surgery among US adults with obesity by diabetes status: 2016-2020
Cheng YJ , Bullard KM , Hora I , Belay B , Xu F , Holliday CS , Simons-Linares R , Benoit SR . BMJ Open Diabetes Res Care 2025 13 (1) INTRODUCTION: Metabolic and bariatric surgery (MBS) is an effective intervention to manage diabetes and obesity. The population-based incidence of MBS is unknown. OBJECTIVE: To estimate the incidence of MBS among US adults with obesity by diabetes status and selected sociodemographic characteristics. RESEARCH DESIGN AND METHODS: This cross-sectional study used data from the 2016-2020 Nationwide Inpatient Sample and Nationwide Ambulatory Surgery Sample to capture MBS procedures. The National Health Interview Survey was used to establish the denominator for incidence calculations. Participants included US non-pregnant adults aged ≥18 years with obesity. The main outcome was incident MBS without previous MBS, defined by International Classification of Diseases, Tenth Revision Procedure Codes, Diagnosis Related Group system codes, and Current Procedural Terminology codes. Adjusted incidence and annual percentage change (2016-2019) were estimated using logistic regression. RESULTS: Among US adults with obesity, over 900 000 MBS procedures were performed in inpatient and hospital-owned ambulatory surgical centers in the USA during 2016-2020. The age- and sex-adjusted incidence of MBS per 1000 adults was 5.9 (95% CI 5.4 to 6.4) for adults with diabetes and 2.0 (95% CI 1.9 to 2.1) for adults without diabetes. MBS incidence was significantly higher for women and adults with class III obesity regardless of diabetes status. The highest incidence of MBS occurred in the Northeast region. Sleeve gastrectomy was the most common MBS surgical approach. CONCLUSIONS: Incident MBS procedures were nearly threefold higher among adults with obesity and diabetes than those with obesity but without diabetes. Continued monitoring of the trends of MBS and other treatment modalities can inform our understanding of treatment accessibility to guide prevention efforts aimed at reducing obesity and diabetes. |

Am J Ophthalmol 2024 265 48-53 ![]() Purpose: To investigate the prevalence, patterns, and predictors of SARS-CoV-2 RNA and culturable virus in tears of a case-ascertained household cohort. Design: Prospective, longitudinal case-ascertained household cohort identified through convenience sampling. MethodsThis analysis was restricted to individuals who were non-hospitalized, symptomatic, and tested positive for SARS-CoV-2 by nasal RT-PCR. Tears and anterior nasal biospecimens were serially collected throughout the acute period. Tears specimens were collected by the study staff using Schirmer test strips, and nasal specimens were self-collected. For both, SARS-CoV-2 RNA was quantified using qRT-PCR, and culturable virus was detected using presence of cytopathic effect (CPE) in tissue culture; positive CPE was confirmed by a qRT-PCR step. A series of cross-sectional unadjusted analyses were performed investigating the relationship between different sociodemographic determinants and biological factors associated with tears RNA positivity. |
Medicaid expansion is not associated with prescription opioid and benzodiazepine misuse among people who inject drugs: A serial cross-sectional observational study using generalized difference-in-differences models
Haley DF , Beane S , Yarbrough CR , Cummings J , Linton S , Ibragimov U , Haardörfer R , Sionean C , Lewis R , Cooper HLF . J Subst Use Addict Treat 2025 171 209639 BACKGROUND: While evidence suggests Medicaid expansion can reduce overdose, some expressed concern expansion fueled the US opioid overdose crisis by increasing access to low-cost prescription opioids diverted for non-prescribed use. Ecologic studies find a protective relationship or no relationship between expansion and area-level opioid prescribing. Little is known about the relationship between expansion and opioid use among people experiencing poverty who inject drugs (PWID), a population at heightened risk of overdose likely to benefit from Medicaid expansion. We examined whether expansion was associated with prescription opioid and benzodiazepine misuse among PWID experiencing poverty and whether associations varied by race/ethnicity and HIV status. METHODS: This serial cross-sectional observational study used generalized difference-in-differences models to analyze data (2012, 2015, 2018) from 19,728 PWID aged 18-64 with income ≤138 % of federal poverty line from 13 states in the CDC's National HIV Behavioral Surveillance. Outcomes included past 12-month non-injection and injection prescription opioid misuse and benzodiazepine misuse. RESULTS: The sample (N = 19,728) was 40 % non-Latinx Black persons and 22 % Latinx persons. Past 12-month non-injection prescription opioid misuse was 33 %, injection prescription opioid misuse was 16 %, and benzodiazepine use was 40 %. Across all models, there was no association between expansion and prescription opioid misuse (confidence intervals included 0) or prescription benzodiazepine misuse (confidence intervals included 0). Associations did not vary by race/ethnicity or HIV status. CONCLUSIONS: We found no association between Medicaid expansion and opioid or benzodiazepine misuse overall, by race/ethnicity, or HIV status among a large, geographically diverse sample of PWID. These findings provide empirical evidence that expansion is not associated with prescription opioid or benzodiazepine misuse in a population likely to benefit from expansion. |
Microbial assessment and performance evaluation of eyewash stations in the laboratory setting
Newcomer DA , Chopra I , Ali IKM , Roy S , Cope JR , Darnell JT . J Occup Environ Hyg 2025 1-14 ![]() Eyewash stations are an essential component of laboratory safety programs, providing first aid in case of ocular exposure to hazardous materials. However, the presence of microbial contamination in these devices poses a potential risk of ocular infection to laboratory employees. This cross-sectional study aimed to evaluate the microbial quality and performance of 40 eyewash stations fixed in 10 buildings in a laboratory setting. Water quality parameters, including temperature, pH, turbidity, and the presence of Acanthamoeba spp., were measured at various time points (first draw, after 2 min of flushing, and 15 min flushing) from samples collected from each of the 40 eyewash stations. Performance and operational data were also measured according to the American National Standards Institute (ANSI)/International Safety Equipment Association (ISEA) Z358.1-2014 standard. Our results showed variable compliance with this standard across measures of physical condition, performance, access, and maintenance. Out of the 147 water samples collected (130 eyewash samples, 17 building reference samples), 28 samples were suspected to contain Acanthamoeba spp. or other free-living amoeba based on initial testing. Further analysis using polymerase chain reaction (PCR) confirmed the presence of Acanthamoeba spp. in 5 out of 28 samples. The results of this study provide insights into the potential risk of ocular infections associated with using eyewash stations and provide the basis for the recommendations on maintenance protocols to minimize the risk of microbial contamination. |
A scoping review to determine if adverse human health effects are associated with use of pyrethroids for mosquito control
Kuczynski Lange S , Connelly CR , Tai Z , Foley N , De Leon Rivera J , Lozano S , Nett RJ . J Med Entomol 2025 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. |
Using the WHO building blocks to examine cross-border public health surveillance in MENA
Buback L , Martin S , Pardo E , Massoud F , Formigo J , Bonyani A , Farag NH , Almayahi ZK , Ishii K , Welty S , Schneider D . Int J Equity Health 2025 24 (1) 38 The introduction of the Sustainable Development Goals by the United Nations has set a global target for achieving Universal Health Coverage, requiring resilient health systems capable of addressing public health emergencies and ensuring health security. Public health surveillance, crucial for detecting and responding to infectious disease outbreaks, is key to building health system resilience. Due to the high levels of mobility and political instability in the Middle East and North Africa (MENA) region, unique challenges arise in cross-border health surveillance. This review aims to highlight the importance of cross-border public health surveillance in strengthening health systems across MENA to achieve equitable health outcomes.A mixed-methods approach was utilized, combining a systematic literature review with semi-structured in-depth interviews (IDIs) involving 28 stakeholders from seven MENA countries. The literature review adhered to PRISMA guidelines, while the IDIs provided qualitative insights into current surveillance practices and challenges. Findings from the literature review and IDIs were triangulated and analyzed using the WHO Health Systems Strengthening (HSS) Building Blocks Framework to identify key challenges and recommendations for improving cross-border surveillance.Results indicate that existing cross-border surveillance systems in MENA face challenges in data collection, analysis, and sharing, with disparities across countries based on income levels and political contexts. Key challenges include delayed and incomplete data sharing, insufficient funding across sectors, inadequate training, inconsistent data definitions, and limited integration of health data for mobile populations. Recommendations emphasize strengthened governance and leadership to facilitate regional cooperation and information sharing, sustainable financing for implementing a One Health approach, utilizing innovative information systems, workforce development to enhance data collection and analysis, and secure supply chains for medicines and vaccines and equitable service delivery for all mobile populations.In conclusion, the WHO HSS Building Block Framework provides a comprehensive approach to assessing and improving cross-border public health surveillance and enhancing health security and equity in MENA. Strengthening cross-border surveillance systems may help MENA countries meet IHR requirements, achieve greater health security, and advance health equity among all types of mobile populations. Despite limitations, the study offers critical insights for improving cross-border surveillance strategies in the region. |
Tuberculosis in the US kidney failure population
Schildknecht KR , Deutsch-Feldman M , Cummins J , Forbes DP , Haddad MB , Apata IW , Wortham JM . J Am Soc Nephrol 2025 BACKGROUND: People with chronic kidney disease (CKD) have a higher risk for progression to tuberculosis disease following infection with Mycobacterium tuberculosis. We produced a nationwide incidence estimate and description of tuberculosis among people with kidney failure. METHODS: We completed a cross-sectional descriptive analysis of people with a reported case of tuberculosis in the United States between 2010 and 2021. We stratified all people with tuberculosis by reported kidney failure status. The primary outcome was tuberculosis incidence among people with kidney failure. We also compared characteristics of people with tuberculosis by reported kidney failure status. RESULTS: Approximately 3% of people (2,892 of 111,155) diagnosed with tuberculosis between 2010 and 2021 also had kidney failure. Annual tuberculosis incidence ranged from 26.1 to 45.4 per 100,000 people with kidney failure and 2.1 to 3.5 per 100,000 people without kidney failure. Among people with kidney failure, 924 (32%) had extrapulmonary tuberculosis only, and nearly 40% died: 286 were diagnosed with tuberculosis after death, and 792 died during treatment. People with tuberculosis and kidney failure had approximately twice the prevalence of a false-negative tuberculin skin test result (39%) compared to people with tuberculosis alone (20%). CONCLUSIONS: Tuberculosis incidence among people with kidney failure between 2010 and 2021 in the United States was 10-fold that among people without kidney failure. |

JAMA Netw Open 2025 8 (1) e2455963 IMPORTANCE: The degree that in-home cannabis smoking can be detected in the urine of resident children is unclear. OBJECTIVE: Test association of in-home cannabis smoking with urinary cannabinoids in children living at home. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used baseline data from Project Fresh Air, a 2012-2016 randomized clinical trial to reduce fine particulate matter levels. Eligible participants were recruited from households in San Diego County, California, with children under age 14 years and an adult tobacco smoker in residence. Children's urine samples were analyzed in 2022. EXPOSURES: In-home cannabis smoking, measured by: parent or guardian report of in-home cannabis smoking; number of daily nonspecific smoking events computed via an air particle count algorithm; and number of daily cannabis smoking events ascertained by residualization, adjusting for air nicotine, tobacco smoking, and other air particle generating or ventilating activities. MAIN OUTCOMES AND MEASURES: Levels of the cannabis biomarker Δ9-tetrahydrocannabinol (THC) and its major metabolites, 11-hydroxy-Δ9-tetrahydrocannabinol and 11-nor-9-carboxy-Δ9-tetrahydrocannabinol. Biomarker molar equivalents were summed to represent total THC equivalents (TTE) in urine. Logistic regression assessed whether in-home smoking was associated with cannabis biomarker detection. For children with detectable urinary cannabinoids, linear regression assessed in-home smoking association with quantity of urinary TTE. RESULTS: A total of 275 children were included in analysis (mean [SD] age, 3.6 [3.6] years; 144 male [52.4%]; 38 Black [13.8%], 132 Hispanic [48.0%], and 52 White [18.9%]). Twenty-nine households (10.6%) reported in-home cannabis smoking in the past 7 days; 75 children [27.3%] had detectable urinary cannabinoids. Odds of detectable TTE in children's urine were significantly higher in households with reported in-home cannabis smoking than households without (odds ratio [OR], 5.0; 95% CI, 2.4-10.4) and with each additional ascertained daily cannabis smoking event (OR, 2.5; 95% CI, 1.6-3.9). Although the point estimate for TTE levels was higher among children with detectable urinary cannabinoids and exposure to more daily cannabis smoking events (increase per event, 35.68%; 95% CI, -7.12% to 98.21%), the difference was not statistically significant. CONCLUSIONS AND RELEVANCE: In this cross-sectional study, in-home cannabis smoking was associated with significantly increased odds of child exposure to cannabis smoke, as assessed by urinary cannabinoid biomarkers. As young children spend most of their time at home, reducing in-home cannabis smoking could substantially reduce their exposure to the toxic and carcinogenic chemicals found in cannabis smoke. |
Adenoviral vector-based vaccine expressing hemagglutinin stem region with autophagy-inducing peptide confers cross-protection against group 1 and 2 influenza A viruses
Wang WC , Sayedahmed EE , Alhashimi M , Elkashif A , Gairola V , Murala MST , Sambhara S , Mittal SK . Vaccines (Basel) 2025 13 (1) ![]() Background/Objectives: An effective universal influenza vaccine is urgently needed to overcome the limitations of current seasonal influenza vaccines, which are ineffective against mismatched strains and unable to protect against pandemic influenza. Methods: In this study, bovine and human adenoviral vector-based vaccine platforms were utilized to express various combinations of antigens. These included the H5N1 hemagglutinin (HA) stem region or HA2, the extracellular domain of matrix protein 2 of influenza A virus, HA signal peptide (SP), trimerization domain, excretory peptide, and the autophagy-inducing peptide C5 (AIP-C5). The goal was to identify the optimal combination for enhanced immune responses and cross-protection. Mice were immunized using a prime-boost strategy with heterologous adenoviral (Ad) vectors. Results: The heterologous Ad vectors induced robust HA stem-specific humoral and cellular immune responses in the immunized mice. Among the tested combinations, Ad vectors expressing SP + HA stem + AIP-C5 conferred significant protection against group 1 (H1N1 and H5N1) and group 2 (H3N2) influenza A viruses. This protection was demonstrated by lower lung viral titers and reduced morbidity and mortality. Conclusions: The findings support further investigation of heterologous Ad vaccine platforms expressing SP + HA stem + AIP-C5. This combination shows promise as a potential universal influenza vaccine, providing broader protection against influenza A viruses. |
Laboratory comparison of rapid antigen diagnostic tests for lymphatic filariasis: STANDARD Q Filariasis Antigen Test (QFAT) versus Bioline Filariasis Test Strip (FTS)
Graves PM , Scott JL , Berg Soto A , Widi AYN , Whittaker M , Lau CL , Won KY . Trop Med Infect Dis 2025 10 (1) ![]() Accurate rapid diagnostic tests (RDTs) are needed to diagnose lymphatic filariasis (LF) in global elimination programmes. We evaluated the performance of the new STANDARD Q Filariasis Antigen Test (QFAT) against the Bioline Filariasis Test Strip (FTS) for detecting W. bancrofti antigen (Ag) in laboratory conditions, using serum (n = 195) and plasma (n = 189) from LF-endemic areas (Samoa, American Samoa and Myanmar) and Australian negative controls (n = 46). The prior Ag status of endemic samples (54.9% Ag-positive) was determined by rapid test (ICT or FTS) or Og4C3 ELISA. The proportion of samples testing positive at 10 min was similar for QFAT (44.8%) and FTS (41.3%). Concordance between tests was 93.5% (kappa 0.87, n = 417) at 10 min, and it increased to 98.8% (kappa 0.98) at 24 h. The sensitivities of QFAT and FTS at 10 min compared to the prior results were 92% (95% CI 88.0-96.0) and 86% (95% CI 80.0-90.0), respectively, and they increased to 97% and 99% at 24 h. Specificity was 98% for QFAT and 99% for FTS at 10 min. Both tests showed evidence of cross-reaction with Dirofilaria repens and Onchocerca lupi but not with Acanthochilonema reconditum or Cercopithifilaria bainae. Under laboratory conditions, QFAT is a suitable alternative RDT to FTS. |
Maybe they’re born with it? Maybe it’s mentoring. A test of the rising star hypothesis
O’Brien KE , Woody BA . J Career Dev 2025 The rising star hypothesis proposes that characteristics of “rising star” protégés already set them up for success, such that mentoring is a byproduct of their ambition. Alternatively, the influential mentor hypothesis states that protégés experience success due to the positive influence of mentoring. Herein, we test whether rising star characteristics (need for achievement and career initiative behaviors) precede or follow informal mentorship. Using data from a sample of 94 protégés (recruited from a hospital) over two time points (six-week lag), we found best evidence for a mix of the rising star and influential mentor hypotheses, in which career initiative behaviors predict the number of informal mentors, and in turn, need for achievement. Cross-lagged effects were probed and provide evidence that the benefits of informal mentoring does not seem to extend to formal mentoring. Practical implications are highlighted, including the benefits of multiple mentors and alternatives to traditional mentoring. © The Author(s) 2025. |
Folate and vitamin B12 status among non-pregnant, non-lactating women of reproductive age and predicted risk for neural tube defects, Morogoro Region, Tanzania
Mai CT , Long K , Lukindo T , Jabbar S , Gwakisa J , Rosenthal J , Zhang M , Yeung LF , Fothergill A , Wang A , Azizi K , Chilumba D , Williams JL , Pfeiffer CM , Caruso E , Leyna GH , Kishimba R . Matern Child Health J 2025 INTRODUCTION: Population risk for neural tube defects (NTDs) can be determined using red blood cell (RBC) folate. However, a paucity of biomarker and surveillance data among non-lactating, non-pregnant women of reproductive age (NPWRA) from Africa limits accurate assessment. Our study assessed folate and vitamin B12 status among non-lactating NPWRA and predicted population risk of NTDs in Tanzania. METHODS: A cross-sectional biomarker survey of non-lactating NPWRA (15-49 years) in the Morogoro region, Tanzania was conducted during June-October 2019. Questionnaire interview responses and non-fasting blood samples were collected. Folate was assessed using the CDC microbiologic assay kit and vitamin B12 was measured using an electrochemiluminescence immunoassay. Complex survey design analyses were conducted using SAS-callable SUDAAN (v11.0.1). RESULTS: Of the 761 participating non-lactating NPWRA, 294 (39.8%) had RBC folate insufficiency (<748 mol/L). The prevalence of RBC folate insufficiency was lower among non-lactating NPWRA living in urban than rural areas (PR: 0.72, 95% CI: 0.52-0.99) but did not differ by age or household wealth index. Vitamin B12 insufficiency was uncommon (< 221 pmol/L, 2.7%). The estimated NTD risk was 10.5 (95% uncertainty interval: 8.1-13.3) per 10,000 births. DISCUSSION: Elevated NTD risk was predicted in the Morogoro region of Tanzania, where ∼ 40% of non-lactating NPWRA had RBC folate insufficiency and < 3% had vitamin B12 insufficiency. The NTD risk is consistent with surveillance data for the area, limited folic acid fortification of staple foods, and low vitamin B12 insufficiency. Further studies are needed to better understand the context of these findings, especially the impact of micronutrient fortification in Tanzania. |
Health care providers' attitudes and knowledge related to tic disorder identification and treatment
Newsome K , Hutchins HJ , Bitsko RH , Robinson LR , Katz SM , Uba N , Rattay KT . J Dev Behav Pediatr 2025 OBJECTIVE: Our study assessed child-serving health care providers' attitudes and knowledge related to identification and treatment of tic disorders including Tourette syndrome (TS), among children. METHODS: We analyzed cross-sectional data from the 2022 Fall DocStyles, a web-based survey of health care providers. The analytic sample included 1058 child-serving providers (403 family practitioners, 232 internists, 251 pediatricians, and 172 nurse practitioners or physician assistants). We calculated point prevalence estimates and 95% confidence intervals and used χ2 tests to statistically test differences by provider type and metro status of practice setting. RESULTS: Less than two-thirds of providers (62.4%) considered evaluation of tics as their role, less than half (40.8%) considered diagnosis of tic disorders their role, and around one-fourth considered treatment of patients with tic disorders to be their role (27.3%). Lack of knowledge of tics/TS and lack of comfort evaluating patients for tics and tic disorders were the most often reported barriers to identification and diagnosis for most provider types, and across practice metro status categories. Online training was the most preferred source of information about tics and tic disorders overall and for each provider type. CONCLUSION: These findings support previous reports indicating challenges in health care provider comfort and knowledge in identifying and diagnosing tic disorders, and the need for more education opportunities around evaluation and diagnosis. Communication and training to support the needs of child-serving providers could improve the access to care for children with tics and tic disorders. |
Suspected mpox symptoms and testing in men who have sex with men in the United States: Cross-sectional study
Atkins K , Carpino T , Rao A , Sanchez T , Edwards OW , Hannah M , Sullivan PS , Ogale YP , Abara WE , Delaney KP , Baral SD . JMIR Public Health Surveill 2025 11 e57399 BACKGROUND: The 2022 mpox outbreak in the United States disproportionately affected gay, bisexual, and other men who have sex with men (GBMSM). Uptake of mpox testing may be related to symptomology, sociodemographic characteristics, and behavioral characteristics. OBJECTIVE: This study aimed to describe suspected mpox symptoms and testing uptake among a sample of GBMSM recruited via the internet in the United States in August 2022. METHODS: We conducted a rapid internet-based mpox survey from August 5 to 15, 2022, among cisgender men 15 years and older who had previously participated in the 2021 American Men's Internet Survey. We estimated the prevalence of suspected mpox symptoms (fever or rash or sores with unknown cause in the last 3 mo) and uptake of mpox testing. We calculated adjusted prevalence ratios (aPRs) and 95% CIs for associations between participant characteristics and suspected mpox symptoms and summarized characteristics of GBMSM reporting mpox testing. Among symptomatic GBMSM who did not receive mpox testing, we described testing self-efficacy, barriers, and facilitators. RESULTS: Of 824 GBMSM, 126 (15.3%) reported at least 1 mpox symptom in the last 3 months; 58/126 (46%) with rash or sores, 57 (45.2%) with fever, and 11 (8.7%) with both. Increased prevalence of suspected mpox symptoms was associated with condomless anal sex (CAS; aPR 1.53, 95% CI 1.06-2.20). Mpox testing was reported by 9/824 GBMSM (1%), including 5 with symptoms. Most GBMSM reporting mpox testing were non-Hispanic White men (7/9 vs 1 Black and 1 Hispanic or Latino man), and all 9 lived in urban areas. Most reported having an sexually transmitted infections test (8/9), 2 or more partners (8/9), CAS (7/9), and group sex (6/9) in the last 3 months. Of those tested, 3 reported living with HIV and all were on treatment, whereas the remaining 6 men without HIV reported current pre-exposure prophylaxis (PrEP) use. Of symptomatic GBMSM who did not report mpox testing, 47/105 (44.8%) had low mpox testing self-efficacy. Among those with low self-efficacy, the most common barriers to testing were not knowing where to get tested (40/47, 85.1%) and difficulty getting appointments (23/47, 48.9%). Among those with high testing self-efficacy (58/105, 55.2%), the most common facilitators to testing were knowing where to test (52/58, 89.7%), convenient site hours (40/58, 69%), and low-cost testing (38/58, 65.5%). CONCLUSIONS: While all GBMSM who reported testing for mpox were linked to HIV treatment or PrEP, those with symptoms but no mpox testing reported fewer such links. This suggests targeted outreach is needed to reduce structural barriers to mpox services among GBMSM in rural areas, Black and Hispanic or Latino GBMSM, and GBMSM living with HIV. Sustaining and scaling community-tailored messaging to promote testing and vaccination represent critical interventions for mpox control among GBMSM in the United States. |
Geographic disparities in physical and mental health comorbidities and socioeconomic status of residence among Medicaid beneficiaries in Utah
Horth RZ , Bose S , Grafe C , Forsythe N , Dunn A . Front Public Health 2024 12 1454783 To examine the relationship between socioeconomic deprivation and complex needs, defined as mental and physical comorbidities, we conducted a cross-sectional retrospective cohort analysis of adult Utah Medicaid beneficiaries. Our analysis included Medicaid beneficiaries with geocoded addresses aged ≥18 years in Utah (N = 157,739). We geocoded beneficiary addresses and assigned them to census block groups. We compared the socioeconomic status of block groups (Singh's area deprivation index) with the proportion of complex needs, defined based on cluster analysis as 1 physical condition with depression or ≥ 2 physical with ≥1 mental health condition. Spatial mapping was performed of prevalence quantiles grouped by count overlaid with Medicaid-covered mental health facilities. Prevalence of complex needs was 18.9% (n = 29,742); beneficiaries with >3 emergency department visits had 12.8 odds of having complex needs; 39.7% of beneficiaries with >$5,000 in annual costs had complex needs. Common comorbid conditions among beneficiaries with complex needs were hypertension (56.0%), hyperlipidemia (35.5%), depression (68.8%), anxiety (56.2%), drug use (16.0%), and alcohol use disorders (15.2%). Census block groups with higher deprivation had a higher proportion of complex needs (ρ = 0.21, p < 0.001). There was a statistically significant spatial autocorrelation of the prevalence of complex needs (Moran's I index: 0.65; p < 0.001). Six high-count census blocks had no mental health facilities. Areas with increased socioeconomic deprivation had a greater proportion of complex needs and fewer mental health facilities. Integrated programs addressing both physical and mental health conditions with a focus on socioeconomically deprived areas might benefit Medicaid recipients in populations such as those in Utah. |
Geographic factors associated with SARS-CoV-2 prevalence during the first wave - 6 districts in Zambia, July 2020
Chanda SL , Imamura T , Malambo W , Bain R , Musuka C , Sinyange N , Hines JZ . BMC Public Health 2025 25 (1) 123 BACKGROUND: Geographical factors can affect infectious disease transmission, including SARS-CoV-2, a virus that is spread through respiratory secretions. Prioritization of surveillance and response activities during a pandemic can be informed by a pathogen's geographical transmission patterns. We assessed the relationship between geographical factors and SARS-CoV-2 prevalence in Zambia. METHODS: We did a cross-sectional study of SARS-CoV-2 prevalence in six districts in July 2020, which was during the upslope of the first wave in Zambia. In each district, 16 Standard Enumeration Areas (SEAs) were randomly selected and 20 households from each SEA were sampled. The SEA PCR prevalence was calculated as the number of persons testing PCR positive for SARS-CoV-2 in the SEA times the individual sampling weight for the SEA divided by the SEA population. We analysed SEA geographical data for population density, socioeconomic status (SES) (with lower scores indicating reduced vulnerability), literacy, access to water, and sanitation, and hygiene (WASH) factors. Gaussian conditional autoregressive (CAR) models and Generalised estimating equations (GEE) were used to measure adjusted prevalence Ratios (aPRs) and 95% confidence intervals (CIs) for SARS-CoV-2 prevalence with geographical factors, after adjusting for clustering by district, in R. RESULTS: Overall, the median SARS-CoV-2 prevalence in the 96 SEAs was 41.7 (Interquartile range (IQR), 0.0-96.2) infections per 1000 persons. In the multivariable CAR analysis, increasing SES vulnerability was associated with lower SARS-CoV-2 prevalence (aPR) = 0.85, 95% CI: 0.78-0.94). Conversely, urban SEAs and poor access to WASH were associated with a higher SARS-CoV-2 prevalence (aPR = 1.73, 95% CI: 1.46-2.03, No soap: aPR = 1.47, 95% CI: 1.05-2.05, households without piped water: aPR = 1.32, 95% CI: 1.05-1.65, 30 min to fetch water: aPR = 23.39, 95% CI: 8.89-61.52). Findings were similar in the multivariable GEE analysis. CONCLUSIONS: SARS-CoV-2 prevalence was higher in wealthier, urban EAs, with poor access to WASH. As this study was conducted early in the first wave could have impacted our findings. Additional analyses from subsequent waves could confirm if these findings persist. During the beginning of a COVID-19 wave in Zambia, surveillance and response activities should be focused on urban population centres and improving access to WASH. |
Spatial analysis of social vulnerability and firearm injury EMS encounters in King County, Washington, 2019-2023
Esie P , Liu J , Brownson K , Poel AJ , Ta M , Pallickaparambil AJ . Public Health Rep 2025 Objectives: In the United States, firearm injuries disproportionately occur in low-income communities and among racial and ethnic minority populations. Recognizing these patterns across social conditions is vital for effective public health interventions. Using timely and localized data, we examined the association between social vulnerability and firearm injuries in King County, Washington. Methods: For this ecological, cross-sectional study, we used health reporting areas (HRAs) (n = 61), a subcounty geography of King County. We obtained HRA-level counts of firearm injuries by using responses from King County emergency medical services (EMS) from 2019 through 2023. We measured HRA-level social vulnerability by using the Social Vulnerability Index (SVI) from the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry, categorized into tertiles (low, moderate, and high SVI). We used bivariate choropleth mapping to illustrate spatial associations between SVI and rates of firearm injuries per 10 000 residents. We used Bayesian spatial negative binomial regression to quantify the strength of these associations. Results: Bivariate choropleth mapping showed a correlation between SVI and rates of firearm injuries. In spatial models, HRAs categorized as high SVI had a 3 times higher rate of firearm injuries than HRAs categorized as low SVI (incidence rate ratio = 3.01; 95% credible interval, 2.02-4.47). Rates of firearm injuries were also higher in HRAs categorized as moderate versus low SVI (incidence rate ratio = 1.72; 95% credible interval, 1.23-2.40). Conclusion: In King County, areas with high social vulnerability had high rates of EMS responses to firearm injuries. SVI can help identify geographic areas for intervention and provide a framework for identifying upstream factors that might contribute to spatial disparities in firearm injuries. © 2024, Association of Schools and Programs of Public Health. |
Prevalence of diagnosed diabetes among U.S. Adults aged ≥18 years with disabilities, 2021-2022
Bardenheier BH , Omura JD , Saaddine JB , Hora I , McKeever Bullard K . Diabetes Care 2025 OBJECTIVE: To compare the prevalence of diagnosed diabetes among U.S. adults with and without disabilities, overall and by subgroups. RESEARCH DESIGN AND METHODS: We used data on adults aged ≥18 years from the cross-sectional 2021-2022 National Health Interview Survey to report the prevalence of diagnosed diabetes by functional disability status and for each disability type (hearing, seeing, mobility, cognition, self-care, and communication) separately. With use of the Washington Group Short Set on Functioning indicator, disability was defined according to the categories of milder (reporting some difficulty), moderate (reporting a lot of difficulty), and severe (cannot do at all) by disability type. Crude prevalence and age-standardized prevalence of diabetes were also calculated for adults with any difficulty with any disability by age, sex, race/ethnicity, education, insurance, and poverty-to-income ratio. RESULTS: Diabetes prevalence increased with number of disability types, was lower among adults with no disability (5.8%) than among those with milder (9.5%) or moderate to more severe (18.3%) disability, and was 4.0-10.3 percentage points higher among those with moderate to more severe disability than among those with milder disability for vision, hearing, mobility, and cognitive disabilities. Diabetes prevalence was similar for adults with milder and moderate to more severe self-care and communication disabilities. CONCLUSIONS: Prevalence of diabetes was higher among adults with any functional disability than without and increased with increasing number of disability types. Adults with multiple disability types, or those who have difficulty with self-care or communication or other moderate to more severe disabilities, may benefit from diabetes prevention programs. |
Evaluation of integrated child health days as a catch-up strategy for immunization in three districts in Uganda
Farahani M , Tindyebwa T , Sugandhi N , Ward K , Park Y , Bakkabulindi P , Kulkarni S , Wallace A , Biraro S , Wibabara Y , Chung H , Reid GA , Alfred D , Atugonza R , Abrams EJ , Igboh LS . Vaccines (Basel) 2024 12 (12) Background: Uganda's Integrated Child Health Day (ICHD) initiative aims to improve children's access to vaccinations. Although widely used as a catch-up vaccination strategy, the effectiveness of the ICHD program in increasing immunization coverage, especially among vulnerable populations, has not been recently evaluated. This study assessed the reach and uptake of ICHD for immunizations in Uganda. Methods: A mixed-methods evaluation was conducted in three districts (Rakai, Kayunga, and Bukedea) where ICHDs occurred. The data collection included a cross-sectional household survey using validated WHO-adapted questionnaires of 1432 caregivers of children under five years old, key informant interviews with 42 health managers and workers, and nine focus group discussions with caregivers between October and December 2022. The vaccines assessed were Bacillus Calmette-Guerin, oral polio, Pentavalent, pneumococcal conjugate, rotavirus (RV), and measles-rubella (MR). Results: The immunization coverage based on child health cards was over 90% for all vaccines except for the second dose of RV (88.3%) and MR (16.2%). Among the children, 2.3% had received no Pentavalent vaccine, and 69.4% were fully vaccinated for their age. Of the 631 children who attended ICHDs, 79.4% received at least one vaccine during the event. Village Health Teams (49%), health workers (18.3%), and megaphone outreach (17.9%) were the primary information sources. Key informants cited challenges with coordination, vaccine delivery, and mobilization. Conclusions: Despite operational challenges, ICHDs appear to have contributed to routine childhood vaccinations. Further research is needed to assess the sustainability and cost-effectiveness of the program. |
Delay of innate immune responses following influenza B virus infection affects the development of a robust antibody response in ferrets
Rowe T , Fletcher A , Lange M , Hatta Y , Jasso G , Wentworth DE , Ross TM . mBio 2025 e0236124 ![]() Due to its natural influenza susceptibility, clinical signs, transmission, and similar sialic acid residue distribution, the ferret is the primary animal model for human influenza research. Antibodies generated following infection of ferrets with human influenza viruses are used in surveillance to detect antigenic drift and cross-reactivity with vaccine viruses and circulating strains. Inoculation of ferrets, with over 1,500 human clinical influenza isolates (1998-2019) resulted in lower antibody responses (HI <1:160) to 86% (387 out of 448) influenza B viruses (IBVs) compared to 2.7% (30 out of 1,094) influenza A viruses (IAVs). Here, we show that the immune responses in ferrets inoculated with IBV were delayed and reduced compared to IAV. Innate gene expression in the upper respiratory tract and blood indicated that IAV generated a strong inflammatory response, including an early activation of the interferon (IFN), whereas IBV elicited a delayed and reduced response. Serum levels of cytokines and IFNs were all much higher following IAV infection than IBV infection. Pro-inflammatory, IFN, TH1/TH2, and T-effector proteins were significantly higher in sera of IAV-infected than IBV-infected ferrets over 28 days following the challenge. Serum levels of Type-I/II/III IFNs were detected following IAV infection throughout this period, whereas Type-III IFN was only late for IBV. An early increase in IFN-lambda corresponded to gene expression following IAV infection. Reduced innate immune responses following IBV infection reflected the subsequent delayed and reduced serum antibodies. These findings may help in understanding the antibody responses in humans following influenza vaccination or infection and consideration of potential addition of innate immunomodulators to overcome low responses. IMPORTANCE: The ferret is the primary animal model for human influenza research. Using a ferret model, we studied the differences in both innate and adaptive immune responses following infection with influenza A and B viruses (IAV and IBV). Antibodies generated following infection of ferrets is used for surveillance assays to detect antigenic drift and cross-reactivity with vaccine viruses and circulating influenza strains. IAV infection of ferrets to generate these reagents resulted in a strong antibody response, but IBV infection generated weak antibody responses. In this study using influenza-infected ferrets, we found that IAV resulted in an early activation of the interferon (IFN) and pro-inflammatory response, whereas IBV showed a delay and reduction in these responses. Serum levels of IFNs and other cytokines or chemokines were much higher in ferrets following IAV infection. These reduced innate responses were reflected the subsequent delayed and reduced antibody responses to IBV in the sera. These findings may help in understanding low antibody responses in humans following influenza B vaccination and infection and may warrant the use of innate immunomodulators to overcome these weak responses. |
Associations between knowledge of health conditions and sugar-sweetened beverage intake among US adults, 2021
Hunter JR , Oza-Frank R , Park S , Sauer AG , Gunn JP . Nutrients 2024 16 (24) BACKGROUND: Frequent consumption of sugar-sweetened beverages (SSB) is associated with an increased risk of some health outcomes. OBJECTIVE: We investigated the relationships between knowledge of health risks related to SSB and SSB intake among adults. METHODS: This cross-sectional study utilized data from the 2021 SummerStyles survey. There were 4022 US adult participants (≥18 years). The outcome variable was SSB intake (none, >0 to <1, 1 to <2, or ≥2 times/day). The exposure variables were knowledge of the association between SSB and seven health conditions. Statistical analyses included seven multinomial regressions to estimate adjusted odds ratios (AOR) for the consumption of SSB according to knowledge of SSB-related health risks after controlling for sociodemographics. RESULTS: Overall, about 30% of adults consumed SSB ≥ 2 times/day. While most adults identified SSB-related conditions such as weight gain (84.0%), diabetes (78.4%), and cavities (74.2%) as being related to drinking SSB, fewer adults recognized related conditions, such as some cancers (23.9%), high cholesterol (28.4%), heart disease (33.5%), and high blood pressure (37.8%). Knowledge of any of the health conditions was not significantly associated with consuming SSB ≥ 2 times/day compared to non-SSB consumers. CONCLUSIONS: Knowledge of SSB-related health conditions varied by sociodemographics but was not associated with high SSB intake. Future studies could explore other factors beyond knowledge that may influence adults' high SSB intake. |
