OBJECTIVE: The objective of this study was to evaluate associations of early-pregnancy plasma per- and polyfluoroalkyl substances (PFAS) with maternal post-pregnancy weight trajectory parameters. METHODS: We studied 1106 Project Viva participants with measures of early-pregnancy plasma concentrations of eight PFAS. We measured weight at in-person visits at 6 months and 3, 7, and 12 years after pregnancy and collected self-reported weight via annual questionnaires up to 17 years after pregnancy. Weight trajectory parameters were estimated via the Superimposition by Translation and Rotation model. We assessed individual and joint effects of PFAS with trajectory parameters using linear regression and Bayesian kernel machine regression (BKMR). RESULTS: Perfluorooctane sulfonate (PFOS) concentrations were positively associated with weight trajectory magnitude in both linear regression (0.8 kg [95% CI: 0.1 to 1.4] per doubling of PFOS) and BKMR analyses (2.6 kg [95% CI: 1.4 to 3.8] per increase from 25th to 75th percentile of PFOS concentrations). Conversely, in BKMR analyses, perfluorononanoate was negatively associated with trajectory magnitude (-2.0 kg [95% CI: -2.9 to -1.1]). In stratified linear regression, older-aged participants had more pronounced positive associations of PFOS, perfluorooctanoate, and 2-(N-ethyl-perfluorooctane sulfonamido) acetate with weight trajectory velocity. No associations were observed with the overall PFAS mixture. CONCLUSIONS: Select PFAS, assessed in pregnancy, may affect maternal weight trajectories spanning 17 years after pregnancy, especially for older-aged individuals.

We conducted a demonstration project of telemedicine HIV care services at the University of Florida (UF) College of Medicine, Jacksonville. Our sample focused on members of racial and ethnic minority groups living in an urban setting. As part of the project's evaluation, we conducted 13 focus groups. Focus groups assessed patient, staff, and provider experiences with facilitating or hindering factors to engaging in telemedicine. We also explored the decision-making processes among people with HIV (PWH) to engage or not in telemedicine. The 46 focus group participants included 21 PWH: 12 PWH who accepted and nine who declined participation in telemedicine. The remaining 25 focus group participants were comprised of medical, clinical support, and community-based organization staff who supported the demonstration project. An unexpected finding that emerged in the focus group narratives detailed that some PWH who accepted telemedicine visits appreciated that telemedicine minimized the stigma they have experienced during in-person healthcare encounters. Among PWH who declined a telemedicine visit, they felt the extension of service into their personal world invaded their privacy, created routes for stigma should their HIV status be disclosed outside the healthcare setting, and raised concerns about confidentiality in virtual settings. Like the PWH, the professionals were mixed in their opinions in that some felt telemedicine facilitated care while others raised concerns. Findings point to the importance of allowing PWH to select the format (in-person or via telemedicine) in which their HIV care is rendered and highlight the importance of intervening to decrease healthcare facility-based stigma.

Prescribed burning is an effective land management tool that provides a range of benefits, including ecosystem restoration and wildfire risk reduction. However, prescribed fires, just like wildfires, introduce smoke that degrades air quality. Furthermore, while prescribed fires help manage wildfire risk, they do not eliminate the possibility of wildfires. It is therefore important to also evaluate fire and smoke impacts from wildfires that may occur after a prescribed burn. In this study, we developed a framework for understanding the air quality and health related trade-offs between wildfires and prescribed fires by simulating a set of counterfactual scenarios including wildfires, prescribed fires, and postprescribed burn wildfires. We applied this framework to the case of the Gatlinburg wildfire and found that emissions from prescribed burns and subsequent wildfire were slightly lower than those from the wildfire itself. This reduction resulted in lower daily average concentrations and exposures of PM(2.5), O(3), and NO(2). Even considering the possibility of a postprescribed burn wildfire, prescribed fires reduced population-weighted daily average PM(2.5), daily maximum 8-h average O(3), and 1-h maximum NO(2) concentrations. In Sevier County, Tennessee where the wildfire occurred, these reductions reached 5.28 μg/m(3), 0.18 ppb, and 1.68 ppb, respectively. The prescribed fires also reduced the person-days smoke exposures from the wildfire. Our results suggest that although prescribed fires cannot eliminate the air quality impacts of wildfires, they can greatly reduce smoke exposure in downwind areas distant from the burn sites.

Local alcohol-based hand rub (ABHR) production systems in low-resource settings, such as in health care facilities (HCFs) in low- and middle-income countries, frequently reuse containers for storing and dispensing ABHR. Cleaning/disinfection (C/D) of ABHR containers is necessary to safely reuse them and is an integral part of the WHO's guidelines on local ABHR production. However, HCFs may not be aware of the need for C/D; combined with suboptimal implementation, this poses a risk of contamination of ABHR. As part of district-led ABHR production in HCFs in five rural districts in Uganda, we developed a standard operating procedure (SOP) for C/D of reused ABHR containers and provided on-site training for infection prevention and control personnel. Using in-person surveys, we assessed the availability of C/D supplies and equipment and the self-reported C/D practices before and after the training. At baseline, almost all (n = 90/91) HCFs reported reusing ABHR containers; 8% and 12% of HCFs routinely had all of the key C/D materials needed for adequately cleaning and disinfecting containers using chlorine and thermal disinfection methods, respectively. HCFs that reported adequately cleaning containers per the SOP increased from 3% (n = 2) at baseline to 18% (n = 16) after the training, whereas adequate disinfection increased from 0% (n = 0) to 5% (n = 5). All HCFs that performed disinfection reported using chlorine, and none reported using thermal disinfection. Improving access to C/D supplies, providing routine mentorship, and monitoring ABHR container C/D are needed to further improve C/D practices.

BACKGROUND: Globally, opioid use remains a major public health problem. In 2019, 480,000 deaths were related to opioid use. Locally, mortality from opioid-involved overdose is high among Illinois residents, with 83 % of ∼4000 overdose deaths during 2022 involving opioids. Treatment for opioid use disorder with buprenorphine, methadone, and naltrexone is approved, safe, and effective. However, significant barriers to treatment remain for many persons. METHODS: In response to new prescribing policy flexibilities, in May 2022, the Chicago Department of Public Health and the Substance Use Prevention and Recovery Division of the Illinois Department of Human Services partnered with a statewide opioid treatment provider, Family Guidance Centers. The partnership started an immediate opioid use disorder treatment helpline program. We performed a descriptive analysis using aggregate data from all calls for assistance with substance use received by the Illinois Helpline during May 9, 2022-March 7, 2024. RESULTS: A total of 2649 unique calls were made to the helpline from persons seeking assistance with substance use, and 1698 unique callers were connected to Family Guidance Centers for treatment initiation. Most callers were prescribed buprenorphine by telemedicine, followed by methadone during in-person treatment. In total, 1515 (89.2 %) of 1698 callers with opioid use disorder were initiated on buprenorphine or methadone through the program. CONCLUSION: A state-wide low-barrier access to medications by telemedicine program is an effective treatment model for the initiation of medications for opioid use disorder.

BACKGROUND: In 2019, there were an estimated 1.2 million persons with HIV (PWH) and 35,100 new infections in the United States. The HIV care continuum has a large influence on transmission dynamics. METHODS: We updated Progression and Transmission of HIV 3.0, an agent-based simulation model, to estimate 2019 HIV transmission rates and distribution of transmissions by the HIV care continuum, race/ethnicity, transmission group, and age group. RESULTS: In 2019, the estimated transmission rate in the United States was 2.94 new infections per 100 person-years (inf /100p-y). Transmission rates decreased along the HIV care continuum; the highest transmission rate was associated with persons with acute HIV infection and unaware of their HIV status at 16.35 inf /100p-y, followed by persons with HIV (non-acute) and unaware of their HIV status (9.52), persons aware of their HIV status and not in care (5.96), persons receiving HIV care (on antiretroviral therapy) but not virally suppressed (4.53), and persons virally suppressed (0). The highest transmission rate by transmission group was among men who have sex with men at 3.68 inf /100p-y. Transmission rates decreased as age increased and are similar by race/ethnicity, after accounting for the HIV care continuum. CONCLUSION: Our results support a continued emphasis on helping PWH move along the care continuum through early diagnosis, linkage to care, and adherence to ART, resulting in viral suppression to reduce HIV transmissions. Further, efforts should focus on reducing disparities in the provision of HIV prevention and care services, particularly for populations disproportionally affected by HIV.

BACKGROUND: Hepatitis B virus (HBV) and hepatitis C virus (HCV) are estimated to be of the most prevalent infectious diseases in correctional settings worldwide. However, viral hepatitis services have not been routinely integrated into South African correctional facilities. We aimed to assess prevalence of HBV infection and HCV infection among people accessing HIV services and assess the feasibility of viral hepatitis service integration in a South African correctional centre. METHODS: Voluntarily participating people in a correctional services facility were offered free hepatitis B surface antigen (HBsAg) and anti-HCV point-of-care testing in addition to routine HIV testing and treatment services on a first-come, first-served basis during June 2021-March 2022. Off-site laboratory testing (HBV and HCV molecular testing and non-invasive liver fibrosis staging) and screening for hepatocellular carcinoma informed further management. A general practitioner at the facility managed participants, with virtual support from hepatologists. Data on age and history of injecting was collected and point-of-care and laboratory results were recorded. Data were analysed using descriptive statistics. RESULTS: The median age of the 765 people who participated was 32.5 years (IQR 27.5 - 38.2), with 2.2% (17/765) reporting having ever injected a drug. The sample prevalence was 3.9% (30/765) for HBV infection, 0.5% (3/665) for HCV infection, and 1.2% (9/765) for HIV-HBV coinfection. Thirty people had reactive HBsAg point-of-care tests. Among those with reactive HBsAg point-of-care tests 90.0% (27/30) received work-up, among whom 48.1% (13/27) were monitored, 44.4% (12/27) were placed on treatment and two people were released before a management plan could be finalised. Of those treated 33.3% (4/12) started tenofovir/emtricitabine and 66.7% (8/12) antiretroviral therapy. Of the eligible participants, 27.3% (201/735) received at least one hepatitis B vaccine dose and 26.9% (54/201) received three doses. All three participants who had confirmed HCV infection were started on direct-acting antivirals. Of the two completing treatment one achieved sustained virological response at 12 weeks (SVR12), one person was released before SVR12 was done. One person was lost to follow-up. No clinical adverse events were reported. CONCLUSION: There was a notable viral hepatitis burden among people in this correctional centre and integration of viral hepatitis services into the existing HIV services was acceptable and feasible. Further efforts to sustain and expand access to viral hepatitis services in South African correctional centres could catalyse national viral hepatitis elimination efforts.

CONTEXT: Federal public health travel restrictions (FPHTR) in the United States are implemented for persons who meet specific criteria to prevent spread of communicable diseases of public health concern. FPHTR can mitigate the risk of disease transmission during air travel and mitigating disease translocation between geographic areas. OBJECTIVE: To characterize and determine the extent of FPHTR implementation during the COVID-19 pandemic. DESIGN: Secondary data analysis. SETTING AND PARTICIPANTS: This report reviewed the U.S. public health response for 3010 persons traveling within, into, and out of, the U.S. who were placed on federal public health travel restrictions during the COVID-19 outbreak from January 1, 2020 to April 6, 2022. MAIN OUTCOME MEASURE: Total number and characteristics of persons with SARS-CoV-2 infection or high-risk exposure added to FPHTR. RESULTS: During this period, FPHTR were implemented for 3010/5460 (55%) persons who were reported to CDC as having tested positive for SARS-CoV-2, or being identified as close contacts of a person with COVID-19, with intention to travel. Of those added to FPHTR lists, 2023/3010 (67%) had confirmed SARS-CoV-2 infection, 975/3010 (32%) were close contacts, and 12/3010 (0.4%) were reasonably believed to have COVID-19 but later confirmed to have another diagnosis and removed. Twenty-six percent (793/3010) of SARS-CoV-2-related FPHTR were for persons reported to CDC after testing positive for SARS-CoV-2 at a testing site located within a U.S. airport. CONCLUSIONS: The extensive application of FPHTR for more than 3000 persons over a period of 29 months during the COVID-19 pandemic was unprecedented. The additional use of FPHTR required extraordinary effort and collaboration among CDC staff and local/state public health agencies for case investigation, reporting, exchange of information, and communication with travelers for case management. Use of this tool should be considered within the context current transmission risk and disease severity.

BACKGROUND: Nursing home residents experience a large burden of invasive methicillin-resistant Staphylococcus aureus (MRSA) infections. Data are limited regarding nursing home characteristics associated with differences in facility-level invasive MRSA rates. METHODS: We analyzed 2011-2015 data from CDC's Emerging Infections Program (EIP) active population- and laboratory-based surveillance for invasive MRSA cases within seven states. A nursing home-onset case was defined as MRSA cultured from a normally sterile site in a person living in a nursing home 3 days before culture collection. Facility rates were calculated as nursing home-onset cases per 100,000 resident-days. Nursing home resident-day denominators and facility characteristics were obtained from four Centers for Medicare & Medicaid Services (CMS) datasets. A general estimating equations model with a logit link assessed characteristics of the facilities with highest rates comprising 50% of nursing home MRSA cases ("high rates"). RESULTS: The 626 nursing homes in the surveillance area had 2824 invasive MRSA cases; 82% of facilities had at ≥1 case. The 20% of facilities with highest rates (≥3.84 cases/100,000 resident-days) had 50% of nursing home-onset cases. In multivariable regression, facilities with high rates were more likely to have CMS-derived characteristics of presence of a resident with a multidrug-resistant organism; or greater proportions of residents who were male, were short stay (in the facility <100 days), had a nasogastric or percutaneous gastrostomy tube, or require extensive assistance with bed repositioning; and more likely to be in an EIP area with higher hospital-onset MRSA rates. Higher registered nurses staffing levels (hours/resident/day) and higher proportions of White residents were associated with lower rates. CONCLUSIONS: Facilities with higher invasive MRSA rates served residents with more clinical and functional care needs. Increasing registered nurse staffing in high-risk facilities might assist with reduction of invasive MRSA rates. These findings could help prioritize nursing homes for future MRSA prevention work.

INTRODUCTION: Most drug-resistant tuberculosis (DR-TB) occurs due to transmission of unsuspected or ineffectively treated DR-TB. The duration of treatment to stop person-to-person spread of DR-TB is uncertain. We evaluated the impact of novel regimens, including BPaL, on DR-TB transmission using the human-to-guinea pig (H-GP) transmission model. METHODS: In Experiment 1, patients initiated an optimized DR-TB regimen including bedaquiline (BDQ) and linezolid (LZD). In Experiment 2, patients initiated the BPaL regimen (BDQ, 1200mg LZD and pretomanid). We measured baseline infectivity for each cohort by exhausting ward air to one of two GP exposure rooms (Control), each containing 90 GPs, for 8 patient-days. Then, after 72 hours of treatment, ward air was exhausted to the second GP exposure room for 8 patient-days (Intervention). The infectiousness of each cohort was compared by performing tuberculin skin tests (TST) in GPs at baseline (pre-treatment) and 6 weeks after the exposure period. RESULTS: In Experiment 1, pre-treatment, five DR-TB patients infected 24/90 (26.7%) GPs (Control). Post-treatment (72 hours after drug initiation), the same patients infected 25/90 (27.8%) GPs (Intervention) (p = 1.00). In Experiment 2, pre-treatment, nine DR-TB patients infected 40/90 (44.4%) GPs (Control). Post-treatment (beginning 72 hours after drug initiation), the same patients infected 0/90 (0%) GPs (Intervention) (p < 0.0001). CONCLUSIONS: In this study, DR-TB drug regimens including BDQ and standard-dose LZD for 72 hours did not decrease DR-TB transmission. In contrast, transmission was rapidly and completely inhibited in patients treated with BPaL for 72 hours, suggesting an early and profound impact on transmission.

In the United States, typhoid vaccination is recommended for international travelers to areas with a recognized risk of typhoid exposure. Using MarketScan® Commercial Database from 2016 through 2022, we estimated typhoid vaccination costs by route (injectable vs. oral) and provider setting (clinic vs. pharmacy). Of 165,930 vaccinated individuals, 99,471 received injectable and 66,459 received oral typhoid vaccines, with 88% and 17% respectively administered at clinics. Average costs for injectable vaccination were $132.91 per person [95% confidence interval (CI): $132.68-$133.13], with clinic and pharmacy costs at $136.38 [95% CI: $136.14-$136.63], and $107.45 [95% CI: $107.13-$107.77] respectively. Oral vaccination costs averaged $81.23 per person [95% CI: $81.14-$81.33], encompassing $86.61 [95% CI: $86.13-$87.10] at clinics and $80.14 [95% CI: $80.09-$80.19] at pharmacies. Out-of-pocket costs comprised 21% and 33% of total costs for injectable and oral vaccinations. These findings may inform clinical decision-making to protect international travelers' health.

OBJECTIVES: Highly pathogenic avian influenza (HPAI) poses an occupational risk for poultry workers, responders, and others in contact with infected birds. The objective of this analysis was to describe HPAI surveillance methods and outcomes, and highlight the challenges, successes, and lessons learned during the Minnesota Department of Health's (MDH's) public health response to HPAI outbreaks in Minnesota poultry flocks in the years 2015 and 2022-2023. METHODS: During both outbreaks, MDH staff attempted to contact all potentially exposed people and conduct a standardized interview. People were considered exposed and at risk if they had entered a barn with poultry on any HPAI test-positive premises. With their consent, exposed persons were entered into illness monitoring until 10 days from their last exposure. In 2015, MDH monitored the health of poultry workers only. In the 2022-2023 response, MDH monitored the health of poultry workers, backyard flock owners, responders, and private contract workers. In 2022-2023, interview responses were entered into a REDCap (Research Electronic Data Capture) database in real time, which automatically entered the person into monitoring if they consented. Through REDCap, they received an automated email with a unique link to a short survey asking about any symptom development. Where appropriate, interview responses from poultry workers collected in 2015 were compared to interview responses from poultry workers collected in 2022-2023. RESULTS: From March 3 to June 5, 2015, MDH epidemiologists interviewed and evaluated 375 (86%) of 435 poultry workers from 110 HPAI-infected flocks. From March 25, 2022 through December 31, 2023, MDH epidemiologists interviewed and evaluated 649 (65%) of 992 poultry workers, responders, contractors, and backyard flock owners associated with 151 HPAI-infected flocks. Among poultry workers, self-reported personal protective equipment (PPE) usage declined significantly from 2015 to 2022-2023 (full PPE usage 51.8% vs. 23.9%, p < .01). CONCLUSION: MDH's long standing relationships with animal health officials and the poultry industry resulted in strong poultry worker participation rates in surveillance efforts during HPAI outbreaks in 2015 and 2022-2023. Self-reported PPE usage was low, particularly in 2022-2023. Improvements in PPE accessibility and technology are needed to protect workers and responders in the on-going HPAI outbreak.

Norovirus is the leading cause of acute gastroenteritis (AGE) globally. Few longitudinal studies have assessed norovirus-associated AGE incidence across age groups in community settings in Latin America. During April 2015-April 2019, active surveillance for AGE among community members of all ages was conducted through household visits two to three times per week in San Jeronimo, Cusco, Peru. An asymptomatic control household was selected for every fifth AGE case. Stool specimens were collected from AGE cases, asymptomatic household members, and control household members, and they were tested for norovirus using real-time reverse transcriptase polymerase chain reaction. Data on illness characteristics were collected from AGE cases during a 15-day follow-up period. Annual means of 247 households and 1,555 participants were enrolled during each April-March surveillance year, accounting for 4,176 person-years (PY) of observation. Of 1,099 AGE events reported, 1,014 stool specimens were tested, and 186 (18%) were norovirus positive. Norovirus AGE incidence was 4.4/100 PY (95% CI: 3.9-5.1); incidence was highest among those younger than 2 years old (60.9/100 PY; 95% CI: 46.8-79.4). Among 672 stool specimens from asymptomatic controls, 56 (8%) tested positive for norovirus. Odds of norovirus detection were significantly higher among cases compared with controls (odds ratio: 2.2; 95% CI: 1.6-3.1). Age-stratified norovirus incidence in this periurban community aligns with previously published estimates and was highest among those younger than 2 years old. Establishing baseline norovirus incidence in specific communities is crucial to identify target populations and assess effectiveness of future interventions, such as vaccines.

BACKGROUND: Institutions of higher education (IHE) have been a focus of SARS-CoV-2 transmission studies but there is limited information on how viral diversity and transmission at IHE changed as the pandemic progressed. METHODS: Here we analyze 3606 viral genomes from unique COVID-19 episodes collected at a public university in Seattle, Washington from September 2020 to September 2022. RESULTS: Across the study period, we found evidence of frequent viral transmission among university affiliates with 60% (n = 2153) of viral genomes from campus specimens genetically identical to at least one other campus specimen. Moreover, viruses from students were observed in transmission clusters at a higher frequency than in the overall dataset while viruses from symptomatic infections were observed in transmission clusters at a lower frequency. Although only a small percentage of community viruses were identified as possible descendants of viruses isolated in university study specimens, phylodynamic modeling suggested a high rate of transmission events from campus into the local community, particularly during the 2021-2022 academic year. CONCLUSIONS: We conclude that viral transmission was common within the university population throughout the study period but that not all university affiliates were equally likely to be involved. In addition, the transmission rate from campus into the surrounding community may have increased during the second year of the study, possibly due to return to in-person instruction.

OBJECTIVES: On July 28, 2022, eastern Kentucky experienced the state's deadliest flood in recorded history. In response to ongoing mental health concerns from community members who survived the flood, local health department directors in affected communities requested technical assistance from the Kentucky Department for Public Health and the Centers for Disease Control and Prevention. METHODS: Two simultaneous Community Assessments for Public Health Emergency Response (CASPERs) were conducted 6 weeks after the flood. Four counties were assessed in each CASPER. EpiInfo7 was used to calculate the unweighted and weighted frequencies and percentages to estimate the number and percentage of households with a particular response in each CASPER. RESULTS: Approximately a third (30.5%) of households in CASPER 1 and approximately 40% of households in CASPER 2 reported experiencing ≥1 mental health problems. Individual-level mental health questions from a modified 3-stage CASPER found approximately 15% of persons in both CASPERs reported a Patient Health Questionnaire-2 (PHQ-2) score ≥3 and approximately 20% of persons in both CASPERs reported Generalized Anxiety Disorder-2 (GAD-2) score ≥3. CONCLUSIONS: These findings indicated households experienced mental health problems after the flood. Depression and anxiety were prevalent among persons living in flood-affected areas. If ever needed, households preferred to receive mental health services in-person and locally.

More than 60 percent of US adults report that they had adverse childhood experiences (ACEs). For this study of 930,000 children born during the period 1999-2003, we used linked administrative, survey, and criminal justice data to measure the association between ACEs (parental death; separation; incarceration; or criminal charge for intimate partner violence, substance use disorder, or child sexual or nonsexual abuse) and socioeconomic disadvantages at ages 18-22 during 2017-21. After childhood socioeconomic status was controlled for, young adults with ACEs were more likely to have been charged with felonies, have become teenage parents, live in a household with poverty or housing assistance, be enrolled in Medicaid, and be employed, and were less likely to be enrolled in an educational institution. These outcomes were most likely among young adults with multiple ACEs or lower childhood socioeconomic status. Using new linked data opportunities, this study provides large-scale, person-level longitudinal evidence of the long-lasting and substantial societal cost of ACEs.

Community-clinical partnerships are an effective approach to connecting primary care with public health to increase disease prevention and screenings and reduce health inequities. We explore how the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) award recipients and clinic teams are using community-clinical linkages to deliver services to populations who are without access to health care and identify barriers, facilitators, and lessons that can be used to improve program implementation. We used purposive sampling to select nine state recipients of the NBCCEDP and a clinic partner for each recipient. The data collection was implemented through a multimodal approach using questionnaires, semistructured interviews, and focus groups. Partnerships between award recipients and clinic teams enhanced planning as clinics were able to optimize the use of electronic medical records to identify women who were not up to date with screening. Partnerships with community organizations, hospital systems, and academic institutions were important to increase community outreach and access to services. These partnerships offered a source of client referrals, a forum to deliver in-person education, a platform for joint dissemination activities to reach a wider audience, collaborations to provide transportation, and coverage for clinical services not available at NBCCEDP participating clinics. In conclusion, partnerships between various organizations are important to enhance planning, increase outreach, and improve access to cancer screening. Internal organizational and external support is important to identify appropriate partners, and technical assistance and training may be beneficial to maintain and optimize community partnerships to address health disparities.

BACKGROUND: In Tajikistan, where there are about 8,000 cases annually, many new cases are being diagnosed with severe disease, indicating a delay in receiving care. We aimed to estimate the proportion with delayed care and the main factors contributing to delayed care. METHODS: Using a retrospective cohort design, we conducted a study that included all people aged over 15 years who were newly diagnosed with pulmonary TB in Dushanbe from 2019 to 2021. We defined 'patient delay' as > 14 days from TB symptom onset to the first provider visit and 'provider delay' as > 3 days from the first visit to treatment initiation. Data was abstracted from medical records and participants were interviewed in-person. Multivariable negative binomial regression was used to estimate adjusted risk ratios (aRR) and 95% confidence intervals (CI). RESULTS: Of 472 participants, 49% were male, 65% had lung tissue cavitation, 33% had drug resistant TB, 11% had diabetes, 4% had HIV, and. Reported cases dropped from 196 in 2019 to 109 in 2020 and increased to 167 in 2021. The proportion of people experiencing patient delays was 82%, 72%, and 90% per year, respectively. The proportion of provider delays was 44%, 41% and 29% per year. Patient delay was associated with year (aRR: 1.09 [CI:1.02-1.18] in 2021 vs. 2019), age (aRR:0.91 [0.82-0.99] for 40-59-year-olds vs. 15-39-year-olds), having HIV (aRR:1.22 [1.08-1.38]), having blood in sputum (aRR:1.19 [1.10-1.28]), chest pain (aRR:1.32 [1.14-1.54]), having at least two structural barriers vs. none (aRR:1.52 [1.28-1.80]), having one of the following barriers: long wait lines (aRR:1.36 [1.03-1.80]), feeling that healthcare services were expensive (aRR:1.54 [1.28-1.85]), or having no time or too much work (aRR:1.54 [1.29-1.84]). Provider delay was associated with year (aRR: 0.67 [0.51-0.89] in 2021 vs. 2019), patients having to pay for X-ray services (aRR: 1.59 [1.22-2.07]) and lacking direct-observed-therapy (DOTS) in facility (aRR: 1.61 [1.03-2.52]). CONCLUSIONS: Patient delay was high before the COVID-19 pandemic and increased in 2021, while provider delay decreased during this time. Addressing structural barriers to healthcare services, such as increased DOTS facilities, expanded hours, and zero fees, may decrease delays.

Thirty-four per cent of deaths among Americans aged 1-46 are due to injury, and many of these deaths could be prevented if all hospitals performed as well as the highest-performing hospitals. The Institute of Medicine and the National Academies of Science, Engineering and Medicine have called for learning health systems, with emphasis on clinical practice guidelines (CPGs) as a means of limiting preventable deaths. Reduction in mortality has been demonstrated when evidence-based trauma CPGs are adhered to; however, guidelines are variably updated, redundant, absent, inaccessible, or perceived as irrelevant. Ultimately, these barriers result in poor guideline implementation and preventable patient deaths. This multidisciplinary group of injury providers, clinical guidance developers and end users, public health and health policy experts and implementation scientists propose key areas for consideration in the definition of an ideal future state for clinical guidance development and dissemination. Suggestions include (1): professional societies collaborate rather than compete for guideline development.(2) Design primary clinical research for implementation, and where relevant, with guideline development in mind.(3) Select clinical topics for guideline development through systematic prioritization, with an emphasis on patient-centered outcomes.(4) Develop guideline authorship groups with a focus on transparency, equity of opportunity and diversity of representation.(5) Establish a plan for regular review and updating and provide the date the guideline was last updated for transparency.(6) Integrate options for adapting the guideline to local resources and needs at the time of development.(7) Make guidelines available on a platform that allows for open feedback and utilization tracking.(8) Improve discoverability of guidelines.(9) Optimize user-experience with a focus on inclusion of bedside-ready, mobile-friendly infographics, tables or algorithms when feasible.(10) Use open access and open licenses.(11) Disseminate clinical guidance via comprehensive and equitable communication channels. Guidelines are key to improve patient outcomes. The proposed focus to ensure trauma guidelines are equitably and effectively developed and disseminated globally.

BACKGROUND: Indoor residual spraying (IRS) is a malaria control strategy implemented before the rainy season. Nchelenge District, Zambia is a holoendemic setting where IRS has been conducted since 2008 with little impact on malaria incidence or parasite prevalence. Pre-rainy season IRS may not reduce the post-rainy season peak abundance of the major vector, Anopheles funestus. METHODS: A controlled, pre-post, prospective cohort study assessed the impact of late-rainy season IRS on malaria prevalence, incidence, hazard, and vector abundance. Three hundred eighty-two individuals were enrolled across four household clusters, of which two were sprayed in April 2022 toward the end of the rainy season. Monthly household and individual surveys and indoor overnight vector collections were conducted through August 2022. Multivariate regression and time-to-event analyses estimated the impact of IRS on outcomes measured by rapid diagnostic tests, microscopy, and quantitative polymerase chain reaction. RESULTS: Seventy two percent of participants tested positive by rapid diagnostic test at least once and incidence by microscopy was 3.4 infections per person-year. Residing in a household in a sprayed area was associated with a 52% reduction in infection hazard (hazards ratio: 0.48, 95% confidence interval [0.29, 0.78]) but not with changes in incidence, prevalence, or vector abundance. The study-wide entomological inoculation rate was 34 infectious bites per person per year. CONCLUSION: Monthly tracking of incidence and prevalence did not demonstrate meaningful changes in holoendemic transmission intensity. However, hazard of infection, which provides greater power for detecting changes in transmission, demonstrated that late rainy season IRS reduced malaria risk.

BACKGROUND: COVID-19 is associated with increased risk of Acute Ischemic Stroke (AIS). The present study examined the impact of prior COVID-19 diagnoses on overall survival among older AIS patients. METHODS: We included 250,079 Medicare Fee-For-Service (FFS) beneficiaries aged ≥65 years with AIS hospitalizations from 04/01/2020 through 12/31/2021. Overall survival was defined as the time from date of AIS hospitalization to date of death, or through end of follow-up on 03/31/2023. We used a Cox proportional hazard model to examine the association between history of COVID-19 and overall survival among AIS beneficiaries, and we obtained age, sex, race/ethnicity, Social Vulnerability Index (SVI), National Institutes of Health Stroke Scale score, and comorbidity-adjusted survival estimates. RESULTS: Among 250,079 Medicare FFS beneficiaries with AIS, 98,327 (39.3%) died during a median of 590 days (IQR, 169-819 days) of follow-up with a total of 365,606 person-years. The 1-year adjusted overall survival was 62.0%, 67.4%, and 68.8% in beneficiaries with hospitalized COVID-19, with non-hospitalized COVID-19 and no COVID-19 respectively (p<0.001). Compared to AIS without history of COVID-19, the adjusted mortality hazard ratios were 1.30 (95% CI, 1.26-1.34) and 1.06 (95% CI, 1.03-1.10) for those with a history of hospitalized and non-hospitalized COVID-19, respectively. The patterns of overall survival by COVID-19 history were largely consistent across age groups, sex, race/ethnicity, and SVI groups. CONCLUSIONS: A history of COVID-19 diagnoses, especially with a history of severe COVID-19, was associated with a significantly higher risk of all-cause mortality among Medicare FFS beneficiaries hospitalized with AIS.

OBJECTIVES: To describe patterns of medication for opioid use disorder (MOUD) during pregnancies in the opioid use disorder (OUD) cohort of MAT-LINK, a sentinel surveillance network of pregnancies at US clinical sites. METHODS: Seven clinical sites providing care for pregnant people with OUD collected electronic health record data. Pregnancies were included in this analysis if (1) the pregnancy outcome occurred between January 2014 and August 2021, (2) the person had OUD, and (3) there was any electronic health record-documented MOUD during pregnancy. Analyses describing MOUD type, demographic characteristics, and timing during pregnancy were performed. RESULTS: Among 3911 pregnancies with any documented MOUD, more than 90% of pregnancies with methadone were to publicly insured people, which was greater than percentages for pregnancies with other MOUD. Buprenorphine with naloxone and naltrexone were two MOUD types that were increasingly common among pregnant people in recent years. In most pregnancies, prenatal care and MOUD were first documented in the same trimester. During the first, second, and third trimesters, there were 37%, 61%, and 91% of pregnancies with MOUD, respectively. Approximately 87% (n = 3412) had only 1 documented MOUD type, versus 2 or 3 types. However, discontinuity in MOUD across trimesters was still observed. CONCLUSIONS: In MAT-LINK's OUD cohort, the overall frequency of MOUD improved over the course of pregnancy. Contextual factors, such as insurance status and year of pregnancy outcome, might influence MOUD type. Prenatal care and MOUD might be facilitators for one another; however, there are still opportunities to improve early linkage and continuous access to both prenatal care and MOUD during pregnancy.

BACKGROUND: On July 28, 2022, floods in eastern Kentucky displaced over 600 individuals. With the goal of understanding mental health needs of affected families, we surveyed households living in flood evacuation shelters after the 2022 Kentucky floods. METHODS: Families experiencing displacement from the 2022 Kentucky floods currently living in three different temporary shelter locations were surveyed via convenience sampling. A rapid community needs assessment involving in-person interviews using modified two stage cluster methodology (CASPER) was conducted between September 6-9, 2022. RESULTS: Teams conducted 61 household interviews. Since the flood, 27.7% reported that their household received services from behavioral health and 19.6% received grief counseling. Experiencing agitation (36.7%), difficulty concentrating (47.5%), nightmares (62.3%), or suicidal thoughts/self-harm (6.6%) were reported by households surveyed. Over one-fourth (27.0%) of individuals surveyed reported being depressed nearly every day. Over 20% reported anhedonia (inability to feel pleasure) nearly every day. Over 75% of individuals surveyed reported being anxious several days or more over the last two weeks. Over one-third of individuals (34.0%) reported being unable to stop worrying nearly every day. Of those individuals surveyed, 36.1% reported barriers to mental health services. CONCLUSIONS: Symptoms of depressed mood, anhedonia, anxiety, and nightmares were prevalent in displaced families six weeks after the 2022 Kentucky floods. Providing and encouraging access to mental health services are important priorities during disaster recovery.

BACKGROUND: Population-based incidence data on young-adult-onset type 1 diabetes and type 2 diabetes are limited. We aimed to examine secular trends in the incidence of diagnosed type 1 diabetes and type 2 diabetes with an age of onset between 15 and 39 years. METHODS: In this multicountry aggregate data analysis, we assembled eight administrative datasets from high-income jurisdictions and countries (Australia, Denmark, Finland, Hungary, Japan, Scotland, South Korea, and Spain [Catalonia]) that had appropriate data available from an international diabetes consortium (GLOBODIAB) describing incidence by diabetes type among people aged 15-39 years from 2000 to 2020. We modelled type 1 diabetes and type 2 diabetes incidence rates using Poisson regression including age and calendar time by sex. FINDINGS: During the years 2000-20, there were 349 591 incident diabetes (both types) cases from 346 million person-years of follow-up among people aged 15-39 years. Over time, there was no statistically significant change in the incidence of type 1 diabetes in Hungary and Japan. The incidence of type 1 diabetes significantly increased in Australia, Denmark, Finland, Scotland, South Korea, and Spain, with annual changes ranging from 0·5% to 6·0%. The incidence of type 2 diabetes significantly increased in four of eight jurisdictions (Denmark, Finland, Japan, and South Korea), with annual increases from 2·0% to 8·5%. The magnitude of increase in incidence of type 2 diabetes was greater in Asian than non-Asian jurisdictions. There was no statistically significant change in type 2 diabetes incidence in Australia and Hungary. The incidence of type 2 diabetes significantly decreased in Scotland and Spain, with annual changes of -0·7% and -1·5%, respectively. INTERPRETATION: There is variability in the trajectory of the incidence of young-adult-onset type 2 diabetes among high-income countries or jurisdictions, with a greater evidence of increase in Asian than non-Asian countries. Evolving trends in the incidence of type 1 and type 2 diabetes in young adults call for the ongoing surveillance of diabetes incidence and a greater research focus on this population.

BACKGROUND: Oral pre-exposure prophylaxis (PrEP) with emtricitabine/tenofovir disoproxil fumarate (F/TDF) has high efficacy against HIV-1 acquisition. Seventy-two prospective studies of daily oral F/TDF PrEP were conducted to evaluate HIV-1 incidence, drug resistance, adherence, and bone and renal safety in diverse settings. METHODS: HIV-1 incidence was calculated from incident HIV-1 diagnoses after PrEP initiation and within 60 days of discontinuation. Tenofovir concentrations in dried blood spots (DBS), drug resistance, and bone/renal safety indicators were evaluated in a subset of studies. RESULTS: Among 17 274 participants, there were 101 cases with new HIV-1 diagnosis (.77 per 100 person-years; 95% confidence interval [CI]: .63-.94). In 78 cases with resistance data, 18 (23%) had M184I or V, 1 (1.3%) had K65R, and 3 (3.8%) had both mutations. In 54 cases with tenofovir concentration data from DBS, 45 (83.3%), 2 (3.7%), 6 (11.1%), and 1 (1.9%) had average adherence of <2, 2-3, 4-6, and ≥7 doses/wk, respectively, and the corresponding incidence was 3.9 (95% CI: 2.9-5.3), .24 (.060-.95), .27 (.12-.60), and .054 (.008-.38) per 100 person-years. Adherence was low in younger participants, Hispanic/Latinx and Black participants, cisgender women, and transgender women. Bone and renal adverse event incidence rates were 0.69 and 11.8 per 100 person-years, respectively, consistent with previous reports. CONCLUSIONS: Leveraging the largest pooled analysis of global PrEP studies to date, we demonstrate that F/TDF is safe and highly effective, even with less than daily dosing, in diverse clinical settings, geographies, populations, and routes of HIV-1 exposure.

Hurricane Ida, a Category 4 hurricane, made landfall in southern Louisiana in August of 2021, causing widespread wind damage and flooding. The objective of this study was to investigate knowledge, attitudes, and practices related to post-hurricane mold exposure and cleanup among residents and workers in areas of Louisiana affected by Hurricane Ida and assess changes in knowledge, attitudes, and practices that have occurred over the past 16 years since Hurricane Katrina. We conducted in-person interviews with 238 residents and 68 mold-remediation workers in areas in and around New Orleans to ask about their mold cleanup knowledge and practices, personal protective equipment use, and risk perceptions related to mold. Knowledge of recommended safety measures increased since the post-Katrina survey but adherence to recommended safety measures did not. Many residents and some workers reported using insufficient personal protective equipment when cleaning up mold despite awareness of the potential negative health effects of mold exposure.

The Black Church has long been an institution of refuge, mobilization, and healing in Black or African American communities. While health promotion interventions have been implemented in the Black Church, little is known about ways to incorporate faith into colorectal cancer (CRC) screening messages. Using modified boot camp translation, a community-based approach, we met with 27 members of the African Methodist Episcopal Church in Atlanta, Georgia, for in-person and virtual sessions to co-create faith-based CRC screening messages and identify channels for sharing information within the church community. Examples of messages developed included "Faith over fear" and "Honor God by taking care of your body." Identified dissemination channels included Sunday service, community events, and social media. Churches serve as key partners in delivering health information, as they are among the most trusted institutions within the Black or African American community.

OBJECTIVE: Pet ownership among people experiencing homelessness (PEH) is common, but access to shelter, veterinary care, and flea-preventative products for PEH who own pets in the US is not well described. We sought to evaluate current knowledge of fleas and flea-borne diseases and characterize practices around pets and service animals among staff at homeless shelters and outreach organizations. METHODS: In-person surveys were administered to staff at homeless shelters and on outreach teams in 7 states from August 2022 to April 2023 to evaluate knowledge, attitudes, and practices and to assess homeless shelter/organizational characteristics. RESULTS: Surveys were administered to 333 staff members at 60 homeless shelters and among 29 outreach teams. Seventy-eight percent of homeless shelters allowed pets or service animals. Only 2% of homeless shelters and 7% of outreach teams provided veterinary care; 15% of homeless shelters and 7% of outreach teams provided flea preventatives. Nearly three-quarters of surveyed homeless shelter staff responded that no steps were taken to treat fleas at their shelters. CONCLUSIONS: Veterinary care and availability of flea-preventative products are limited in homeless shelter and outreach organizations serving people experiencing homelessness. CLINICAL RELEVANCE: Pets of PEH might be at an increased risk of flea infestation and flea-borne diseases because of limited access to veterinary care and preventatives. Improving knowledge and access to flea prevention, screening, and treatment are critical to ensure PEH and their pets can consistently access homeless shelters or outreach services, and to prevent flea-borne disease transmission.

BACKGROUND AND OBJECTIVES: Blood donor cohorts are an underappreciated resource for surveillance and public health programming for infectious diseases. The incidence of hepatitis C virus (HCV) infection was evaluated in repeat blood donors in Georgia. MATERIALS AND METHODS: Using data from the national hepatitis C screening registry, we calculated overall hepatitis C incidence for 2017-2023 and annual incidence during 2017-2022 among adults who donated blood at least twice and had a nonreactive HCV antibody (anti-HCV) test result upon first screening and a subsequent anti-HCV test conducted in any location. Rates of anti-HCV seroconversion and current infection were calculated by year, sex, age group, and location of last HCV screening and expressed per 100,000 person-years (PY). RESULTS: Of 101,443 blood donors with ≥2 anti-HCV results,775 (0.8%) seroconverted to anti-HCV reactive, of whom 403 (52.0%) had current infection. Incidence of anti-HCV seroconversion decreased from 408 per 100,000 PY in 2017 to 218 per 100,000 PY in 2022 and incidence of infection decreased from 172 per 100,000 PY in 2017 to 118 per 100,000 PY in 2022. Males, persons aged 18-39 years, and people last tested for HCV in prisons had the highest incidence rates for anti-HCV seroconversion and HCV infection, while persons last screened in blood banks and during antenatal care had the lowest. CONCLUSION: Despite the observed decline, incidence of HCV infection among repeat blood donors remains high in specific subgroups. Hepatitis C prevention, screening and treatment interventions need to particularly focus on incarcerated populations and young adults in Georgia.

Comprehensive prenatal care incorporates recommended vaccines to help protect the mother, the pregnancy, and the infant from adverse health outcomes and severe illness from vaccine preventable diseases (VPDs). However, vaccinations during pregnancy remain underutilized, often influenced by concerns about vaccine safety and low perception of disease risk. Self-reported vaccine hesitancy among pregnant people in the United States has significantly increased in the last few years, and influenza and Tdap (tetanus, diphtheria, and pertussis) vaccination rates have declined. Furthermore, the number of vaccines routinely recommended during pregnancy has expanded. Communication strategies tailored to pregnant people may help build vaccine confidence among pregnant people and their health care providers. While characteristics and perceptions associated with hesitancy to vaccinate during pregnancy are documented in existing literature, more information is needed on promising communication practices preferred by subgroups of pregnant persons, particularly Black pregnant people who have higher rates of illness from VPDs and greater risk of pregnancy-related complications. This article summarizes literature on the current landscape of prenatal vaccination, discusses qualitative findings from focus groups with non-Hispanic Black pregnant people, and describes promising practices for communicating with this group about vaccination. Promising practices include specifying the benefits of vaccination for both the pregnant person and the infant, outlining potential risks, and emphasizing the overall importance of vaccination during pregnancy, while also acknowledging that many non-Hispanic Black pregnant people may have health concerns they perceive as superseding vaccination.
