BMC Neurol 2024 24 (1) 399 BACKGROUND: Chronic overlapping pain conditions (COPCs), pain-related conditions that frequently occur together, may occur in patients with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and could impact illness severity. This study aimed to identify comorbid COPCs in patients with ME/CFS and evaluate their impact on illness severity. METHODS: We used data from 923 participants in the Multi-Site Clinical Assessment of ME/CFS study, conducted in seven U.S. specialty clinics between 2012 and 2020, who completed the baseline assessment (595 ME/CFS and 328 healthy controls (HC)). COPCs included chronic low back pain (cLBP), chronic migraine/headache (cMHA), fibromyalgia (FM), interstitial cystitis/irritable bladder (IC/IB), irritable bowel syndrome (IBS), temporomandibular disorder (TMD). Illness severity was assessed through questionnaires measuring symptoms and functioning. Multivariate analysis of variance and analysis of covariance models were used for analyses. Log-binomial regression analyses were used to compute prevalence of COPCs and prevalence ratios (PR) between groups with 95% confidence intervals. Both unadjusted and adjusted results with age and sex are presented. RESULTS: 76% of participants with ME/CFS had at least one COPCs compared to 17.4% of HC. Among ME/CFS participants, cMHA was most prevalent (48.1%), followed by FM (45.0%), cLBP (33.1%), and IBS (31.6%). All individual COPCs, except TMD, were significantly more frequent in females than males. The unadjusted PR (ME/CFS compared to HC) was highest for FM [147.74 (95% confidence interval (CI) = 20.83-1047.75], followed by cLBP [39.45 (12.73-122.27)], and IC/IB [13.78 (1.88-101.24)]. The significance and order did not change after age and sex adjustment. The COPC comorbidities of cLBP and FM each had a significant impact on most health measures, particularly in pain attributes (Cohen's d effect size 0.8 or larger). While the impact of COPC comorbidities on non-pain attributes and quality of life measures was less pronounced than that on pain, statistically significant differences between ME/CFS participants with and without COPCs were still evident. CONCLUSIONS: More than 75% of ME/CFS participants had one or more COPCs. Multiple COPCs further exacerbated illness severity, especially among females with ME/CFS. Assessment and management of COPCs may help improve the health and quality of life for patients with ME/CFS. |
| National health and economic impact of a lifestyle program to prevent type 2 diabetes mellitus in Germany: a simulation study
Ogurtsova K , Laxy M , Emmert-Fees K , Dintsios CM , Zhang P , Icks A . BMJ Open Diabetes Res Care 2024 12 (5) INTRODUCTION: To examine the long-term health and economic impact of a lifestyle diabetes prevention program in people with high risk of developing type 2 diabetes in Germany. RESEARCH DESIGN AND METHODS: We assessed the lifetime cost-effectiveness of a 2-year pragmatic lifestyle program for preventing type 2 diabetes targeting German adults aged 35-54 and 55-74 years old with hemoglobin A1c (HbA1c) from 6.0% to 6.4%. We used the Centers for Disease Control and Prevention RTI Diabetes Cost-Effectiveness Model to run a simulation on the program effectiveness. We estimated incremental health benefits in quality-adjusted life years (QALYs) and costs using an established simulation model adapted to the German context, from a healthcare system and societal perspective. The cost-effectiveness of the program was measured by incremental cost-effectiveness ratios (ICERs) in cost per QALY. We projected the number of type 2 diabetes cases prevented by participation rate if the program was implemented nationwide. RESULTS: The lifestyle program would result to more QALYs and higher costs. The lifetime ICERs were 14 690€ (35-54 years old) and 14 372€ (55-74 years old) from a healthcare system perspective and cost saving (ICER=-3805€) and cost-effective (ICER=4579€), respectively, from a societal perspective. A total of 10 527 diabetes cases would be prevented over lifetime if the program was offered to all eligible people nationwide and 25% of those would participate in the program. CONCLUSIONS: Implementing the lifestyle intervention for people with HbA1c from 6.0% to 6.4% could be a cost-effective at standard willingness to pay level strategy for type 2 diabetes prevention. The intervention in the younger cohort could be cost saving from a societal perspective. The successful implementation of a lifestyle-based diabetes prevention program could be an important component of a successful National Diabetes Strategy in Germany. |
| Prevalence of glaucoma among US adults in 2022
Ehrlich JR , Burke-Conte Z , Wittenborn JS , Saaddine J , Omura JD , Friedman DS , Flaxman AD , Rein DB . JAMA Ophthalmol 2024 IMPORTANCE: Glaucoma is the leading cause of irreversible blindness worldwide and, in the US, disproportionately affects people from racial and ethnic minority groups. Glaucoma prevalence has not been estimated for the US in more than a decade, and state- and county-level estimates are not available. OBJECTIVE: To estimate glaucoma and vision-affecting glaucoma prevalence by demographic factors and US state and county for the Centers for Disease Control and Prevention's Vision and Eye Health Surveillance System (VEHSS). DATA SOURCES: This meta-analysis used data from the National Health and Nutrition Examination Survey (2005-2008), Medicare fee-for-service claims (2019), IBM MarketScan commercial insurance claims (2016), population-based studies of eye disease (1985-2003), and 2022 population estimates from the US Census Bureau. STUDY SELECTION: PubMed was searched for population-based studies of glaucoma prevalence published between 1991 and 2016. DATA EXTRACTION AND SYNTHESIS: Bayesian meta-regression methods were used to estimate the prevalence of glaucoma and vision-affecting glaucoma stratified by age, undifferentiated sex/gender (a measure that captures an unclear mix of aspects of sex and or gender), race and ethnicity, and US county and state. MAIN OUTCOMES AND MEASURES: Prevalence of any type of glaucoma (open or closed angle) among people 18 years or older and vision-affecting glaucoma, defined as glaucoma and a visual field abnormality. RESULTS: For 2022, an estimated 4.22 million people (95% uncertainty interval [UI], 3.46 million to 5.23 million) in the US were living with glaucoma, with a prevalence of 1.62% (UI, 1.33%-2.00%) among people 18 years or older and 2.56% (UI, 2.10%-3.16%) among people 40 years or older. An estimated 1.49 million people (UI, 1.17 million to 1.90 million) were living with vision-affecting glaucoma, with a prevalence of 0.57% (UI, 0.45%-0.73%) among people 18 years or older and 0.91% (UI, 0.71%-1.16%) among people 40 years or older. Prevalence of glaucoma among people 18 years or older ranged from 1.11% (UI, 0.89%-1.40%) in Utah to 1.95% (UI, 1.57%-2.39%) in Mississippi. Black adults had a prevalence of 3.15% (UI, 2.32%-4.09%) compared with 1.42% (UI, 1.10%-1.85%) among White adults; adults in the Hispanic and all other racial and ethnic categories combined had a prevalence of 1.56% (UI, 1.13%-2.06%). CONCLUSIONS AND RELEVANCE: This meta-analysis found that an estimated 2.56% of people 40 years or older have glaucoma, slightly more than estimated by previous studies. Black individuals are disproportionately affected. Prevalence estimates at the state and county level can help guide public health planning. |

| Prevalence of self-reported diagnosed diabetes among adults, by county metropolitan status and region, United States, 2019-2022
Onufrak S , Saelee R , Zaganjor I , Miyamoto Y , Koyama AK , Xu F , Pavkov ME , Bullard KM , Imperatore G . Prev Chronic Dis 2024 21 E81 INTRODUCTION: Previous research suggests that rural-urban disparities in diabetes mortality, hospitalization, and incidence rates may manifest differently across US regions. However, no studies have examined disparities in diabetes prevalence by metropolitan residence and region. METHODS: We used data from the 2019-2022 National Health Interview Survey to compare diabetes status, socioeconomic characteristics, and weight status among adults in each census region (Northeast, Midwest, South, West) according to county metropolitan status of residence (large central metro, large fringe metro, small/medium metro, and nonmetro). We used χ(2) tests and logistic regression models to assess the association of metropolitan residence with diabetes prevalence in each region. RESULTS: Diabetes prevalence ranged from 7.0% in large fringe metro counties in the Northeast to 14.8% in nonmetro counties in the South. Compared with adults from large central metro counties, those from small/medium metro counties had significantly higher odds of diabetes in the Midwest (age-, sex-, and race and ethnicity-adjusted odds ratio [OR] = 1.24; 95% CI, 1.06-1.45) and South (OR = 1.15; 95% CI, 1.02-1.30). Nonmetro residence was also associated with diabetes in the South (OR = 1.62 vs large central metro; 95% CI, 1.43-1.84). After further adjustment for socioeconomic and body weight status, small/medium metro associations with diabetes became nonsignificant, but nonmetro residence in the South remained significantly associated with diabetes (OR = 1.22; 95% CI, 1.07-1.39). CONCLUSION: The association of metropolitan residence with diabetes prevalence differs across US regions. These findings can help to guide efforts in areas where diabetes prevention and care resources may be better directed. |

BACKGROUND: Streptococcus pneumoniae (S. pneumoniae), Haemophilus influenzae (H. influenzae), and Neisseria meningitidis (N. meningitidis) are leading causes of childhood bacterial meningitis and preventable by vaccines. The aim of this hospital-based sentinel surveillance is to describe the epidemiological characteristics of pneumococcal meningitis, including disease burden, and to provide baseline data on pneumococcal serotype distribution to support decision making for pneumococcal conjugate vaccine (PCV) introduction in Vietnam. METHODS: Surveillance for probable bacterial meningitis in children 1-59 months of age is conducted in three tertiary level pediatric hospitals: one in Hanoi and two in Ho Chi Minh City. Cerebrospinal fluid (CSF) specimens were collected via lumbar puncture from children with suspected meningitis. Specimens were transferred immediately to the laboratory department of the respective hospital for cytology, biochemistry, and microbiology testing, including culture. PCR testing was conducted on CSF specimens for bacterial detection (S. pneumoniae, H. influenzae, and N. meningitidis) and pneumococcal serotyping. RESULTS: During 2015-2018, a total of 1,803 children with probable bacterial meningitis were detected; 1,780 had CSF specimens available for testing. Of 245 laboratory-confirmed positive cases, the majority were caused by S. pneumoniae (229,93.5%). Of those with S. pneumoniae detected, over 70% were caused by serotypes included in currently available PCV products; serotypes 6 A/6B (27.1%), 14 (19.7%), and 23 F (16.2%) were the most common serotypes. Children with laboratory-confirmed pneumococcal meningitis were more likely to live in Hanoi (p < 0.0001) and children 12-23 months of age were at greater odds (OR = 1.65, 95% CI: 1.11, 2.43; p = 0.006) of having confirmed pneumococcal meningitis compared to children < 12 months of age when compared to those without laboratory-confirmed bacterial meningitis. Additionally, children with confirmed pneumococcal meningitis were more likely to exhibit signs and symptoms consistent with clinical meningitis compared to negative laboratory-confirmed meningitis cases (p < 0.0001) and had a greater odds of death (OR = 6.18, 95% CI: 2.98, 12.86; p < 0.0001). CONCLUSIONS: Pneumococcal meningitis contributes to a large burden of bacterial meningitis in Vietnamese children. A large proportion are caused by serotypes covered by PCVs currently available. Introduction of PCV into the routine immunization program could reduce the burden of pneumococcal meningitis in Viet Nam. |
| Test and treat approach for tuberculosis infection amongst household contacts of drug-susceptible pulmonary tuberculosis, Mumbai, India
Shah D , Bhide S , Deshmukh R , Smith JP , Kaiplyawar S , Puri V , Yeldandi V , Date A , Nyendak M , Ho CS , Moonan PK . Front Tuberc 2024 2 BACKGROUND: Mumbai is one of the most densely populated areas in the world and is a major contributor to the tuberculosis (TB) epidemic in India. A test and treat approach for TB infection (TBI) amongst household contacts (HHC) is part of the national policy for TB preventive treatment (TPT). However, in practice, the use of interferon-gamma release assay (IGRA) tests for infection are limited, and prevalence of TBI in Mumbai is not known. METHODS: We conducted a cross-sectional study among HHCs exposed to persons with microbiologically-confirmed, drug-susceptible pulmonary TB that were notified for antituberculosis treatment in Mumbai, India during September-December, 2021. Community-based field workers made home visits and offered IGRA (QuantiFERON-TB(®) Gold In-Tube Plus) tests to HHC aged 5 years and older. After ruling out active TB disease, HHC with IGRA-positive test results were referred for TPT. All HHC were monitored for at least 24 months for progression to active TB disease. RESULTS: Among 502 HHCs tested, 273 (54%) had IGRA-positive results. A total of 254 (93%) were classified as TBI and were eligible for TPT, of which 215 (85%) initiated TPT, and 194 (90%) completed TPT successfully. There was substantial variation in rates of TBI per household. In 32% of households, all HHC (100%) were IGRA positive and in 64% of households >50% of HHC were infected. In all, 22 HHCs (4%; 22/558) were diagnosed with TB disease; of these, five HHC were diagnosed during follow up, of which three were IGRA positive and had no evidence of disease at initial screening but chose not to initiate TPT. CONCLUSION: A test and treat strategy for HHC resulted in the detection of a substantial proportion of TBI and secondary TB cases. Home-based IGRA testing led to high participation rates, clinical evaluations, TPT initiation, and early diagnoses of additional secondary cases. A community-focused, test and treat approach was feasible in this population and could be considered for broader implementation. |
| Assessment of public health impact of 20 non-research HIV demonstration projects by use of the CDC science impact framework, United States, 2018-2022
Beltrami J , Carree T , Spikes P , Mulatu MS , Ajoku S , Dunbar E . J Public Health Manag Pract 2024 Compared with traditional measures of scientific impact, the CDC Science Impact Framework more broadly, directly, and quickly assesses impact of public health science. For 20 CDC-funded HIV prevention projects that were conducted during 2018-2022, health departments documented impact, based on CDC Science Impact Framework domains: Disseminating Science, Creating Awareness, Catalyzing Action, Effecting Change, and Shaping the Future. Health departments reported 282 impacts: the most common were new partnerships (n = 17, Catalyzing Action), capacity building (n = 16, Effecting Change), new projects or initiatives begun (n = 15, Shaping the Future), new collaborations (n = 14, Catalyzing Action), improved program (n = 13, Shaping the Future), new guidelines or practices (n = 13, Effecting Change), and informed persons affected by work (n = 13, Creating Awareness). Health departments documented substantial impact with a simple, timely, and broad approach. Demonstrating impact is important for community-based organizations, funders, and others interested in public health and helps them better understand the value of public health. |

Health Secur 2024 22 (5) 353-362 National public health emergency operations centers (PHEOCs) serve as hubs for coordinating information and resources for effective emergency management. In the International Health Regulations (IHR 2005) Monitoring and Evaluation Framework, a simulation exercise is 1 of 4 components that can be used to test the functionality of a country's emergency response capabilities in a simulated situation. To test the functionality of PHEOCs in World Health Organization African Region member states, a regional functional exercise simulating an Ebola virus disease outbreak was conducted. The public health actions taken in response to the simulated outbreak were evaluated against the exercise objectives. Thematic analysis was conducted to summarize key strengths and areas for improvement. From December 6 to 7, 2022, more than 1,000 representatives from 36 of the 47 African Region member states participated in the exercise from their respective PHEOCs. Approximately 95% of the 461 participants polled agreed with the positive responses to the postexercise survey. More than half of the PHEOC participants were able to test their existing emergency preparedness and response plans and became familiar with the expected roles to be fulfilled during an event. Of the participants who responded to the survey, over 90% reported that the exercise helped them understand their roles during emergency management. The exercise met its objectives and provided an opportunity to test the functionality of PHEOCs using realistic scenarios, and it helped participants understand existing response systems and procedures. However, the exercise also revealed areas for improvement in terms of the timing and preparation of participants. We recommend conducting functional exercises at the regional and national levels at least once a year, early or midyear, to allow many stakeholders to take part in the exercise. Moreover, there is a need to train country-level evaluators and controllers in designing and conducting functional exercises. |
| A scoping review to determine if adverse human health effects are associated with use of organophosphates for mosquito control
Tai Z , Connelly CR , Kuczynski Lange S , Foley N , De Leon Rivera J , Lozano S , Nett RJ . J Med Entomol 2024 Organophosphate insecticides are widely used for adult mosquito control. Although proven effective in reducing mosquito populations and limiting arbovirus transmission, public concern exists regarding potential human health effects associated with organophosphate exposure. The aim of this scoping review was to describe any reported human health conditions associated with organophosphates during their use for adult mosquito control in the United States and Canada. Original peer-reviewed articles published in English language journals from 1 January 2000 to 22 May 2024, were obtained by searching from the databases MEDLINE, EMBASE, Agricultural & Environmental Science Collection, CAB Abstracts, and Scopus. The search identified 6,154 screened articles. Following an independent review, 10 studies were identified that described human health conditions associated with organophosphate exposure during adult mosquito control applications. Of the 10 included studies, only two articles were published within the last 11 years (2013 to 22 May 2024). Three types of study design were represented in the included studies: cohort (n = 5), case study (n = 1), and risk assessment (n = 4). The included studies could not determine causality between exposure to adulticides and development of illness or adverse impacts. Exposure to organophosphates did not contribute to an observed increase in metabolic toxicity, hospitalization rates, or self-reported symptoms and exposure. The available and limited evidence indicates that organophosphates can be used safely to control nuisance mosquitoes or mosquitoes that transmit arboviruses. Continued research regarding the human health effects associated with organophosphate applications for adult mosquito control could help evaluate the basis of the public's concerns and inform public health decision-making. |
| Factors affecting chlorinated product formation from sodium hypochlorite bleach and limonene reactions in the gas phase
Walsh CM , Baughman NN , Ham JE , Wells JR . ACS EST Air 2025 10 (1) 1317-1328 During use of sodium hypochlorite bleach, gas-phase hypochlorous acid (HOCl) and chlorine (Cl2) are released, which can react with organic compounds present in indoor air. Reactivity between HOCl/Cl2 and limonene, a common constituent of indoor air, has been observed. The purpose of this study was to characterize the chemical species generated from gas-phase reactions between HOCl/Cl2 and limonene. Gas-phase reactions were prepared in Teflon chambers housing HOCl, Cl2, and limonene. The resulting chemical products were analyzed using gas-phase preconcentration, followed by gas chromatography and high-resolution mass spectrometry. Several chlorinated products were detected, including limonene species containing one, two, and three chlorines and limonene chlorohydrin. Product concentrations and yields were estimated for the most abundant products, and greater than 80% of transformed limonene was represented in the detected products. Temporal sampling of the reactions allowed time courses to be plotted for limonene decay and chlorinated limonene product generation under different conditions, including the treatments of HOCl/Cl2, Cl2 only, high vs low relative humidity, and +/- ozone. These experiments add product speciation, yield estimates, and an understanding of environmental factors affecting product formation to previous studies, further highlighting the chemical transformations initiated by sodium hypochlorite bleach in indoor air. |

BACKGROUND: Blastomycosis is an environmentally acquired fungal infection that can result in severe pulmonary illness and high hospitalization rates. In 2023, a blastomycosis outbreak was detected among workers at a paper mill in Delta County, Michigan. METHODS: We included patients with clinical and laboratory evidence of blastomycosis who had spent ≥40 hours in Delta County since September 1, 2022 and had illness onset December 1, 2022-July 1, 2023. We assessed epidemiological and clinical features of patients and evaluated factors associated with hospitalization. We performed whole-genome sequencing to characterize genetic relatedness of clinical isolates from eight patients. RESULTS: In total, 131 patients were identified; all had worked at or visited the mill. Sixteen patients (12%) were hospitalized; one died. Compared with non-hospitalized patients, more hospitalized patients had diabetes (p=0.03) and urine antigen titers above the lower limit of quantification (p<0.001). Hospitalized patients were also more likely to have had ≥1 healthcare visits before receiving a blastomycosis diagnostic test (p=0.02) and to have been treated with antibiotics prior to antifungal prescription (p=0.001). All sequenced isolates were identified as Blastomyces gilchristii and clustered into a distinct outbreak cluster. CONCLUSIONS: This was the largest documented blastomycosis outbreak in the United States. Epidemiologic evidence indicated exposures occurred at or near the mill, and genomic findings suggested a common exposure source. Patients with diabetes may have increased risk for hospitalization, and elevated urine antigen titers could indicate greater disease severity. Early suspicion of blastomycosis may prompt earlier diagnosis and treatment, potentially reducing unnecessary antibiotic prescriptions and improving patient outcomes. |
| The impact of changing exposure to PM(2.5) on mortality for US diplomats with multiple international relocations: a modelling study
Edwards L , Milner J , Wilkinson P , Milojevic A . Environ Health 2024 23 (1) 89 BACKGROUND: Current evidence linking long-term exposure to fine particulate matter (PM(2.5)) exposure and mortality is primarily based on persons that live in the same residence, city and/or country throughout the study, with few residential moves or relocations. We propose a novel method to quantify the health impacts of PM(2.5) for United States (US) diplomats who regularly relocate to international cities with different PM(2.5) levels. METHODS: Life table methods were applied at an individual-level to US mortality statistics using the World Health Organization's database of city-specific PM(2.5) annual mean concentrations. Global Burden of Disease concentration-response (C-R) functions were used to estimate cause-specific mortality and days of life lost (DLL) for a range of illustrative 20-year diplomatic assignments for three age groups. Time lags between exposure and exposure-related mortality risks were applied. Sensitivity analysis of baseline mortality, exposure level, C-R functions and lags was conducted. The effect of mitigation measures, including the addition of air purifiers, was examined. RESULTS: DLL due to PM(2.5) exposure for a standard 20-year assignment ranged from 0.3 days for diplomats' children to 84.1 days for older diplomats. DLL decreased when assignments in high PM(2.5) cities were followed by assignments in low PM(2.5) cities: 162.5 DLL when spending 20 years in high PM(2.5) cities compared to 62.6 DLL when spending one of every four years (5 years total) in a high PM(2.5) city for older male diplomats. Use of air purifiers and improved home tightness in polluted cities may halve DLL due to PM(2.5) exposure. The results were highly sensitive to lag assumptions: DLL increased by 68% without inception lags and decreased by 59% without cessation lags for older male diplomats. CONCLUSION: We developed a model to quantify health impacts of changing PM(2.5) exposure for a population with frequent relocations. Our model suggests that alternating assignments in high and low PM(2.5) cities may help reduce PM(2.5)-related mortality burdens. Adding exposure mitigation at home may help reduce PM(2.5) related mortality. Further research on outcome-specific lag structures is needed to improve the model. |
| Exploring diet as a source of plasticizers in pregnancy and implications for maternal second-trimester metabolic health
Pacyga DC , Jolly L , Whalen J , Calafat AM , Braun JM , Schantz SL , Strakovsky RS . Environ Res 2024 120198 BACKGROUND AND OBJECTIVES: Diet plays critical roles in modulating maternal metabolic health in pregnancy, but is also a source of metabolic-disrupting phthalates and their replacements. We aimed to evaluate whether the effects of better diet quality on favorable maternal metabolic outcomes could be partially explained by lower exposure to phthalates/replacements. METHODS: At 13 weeks gestation, 295 Illinois women (enrolled 2015-2018) completed a three-month food frequency questionnaire that we used to calculate the Alternative Healthy Eating Index (AHEI)-2010 diet quality index. We quantified 19 metabolites, reflecting exposure to 10 phthalates/replacements, in a pool of five first-morning urine samples collected monthly across pregnancy. We measured 15 metabolic biomarkers in fasting plasma samples collected at 17 weeks gestation, which we reduced to five uncorrelated principal components (PCs), representing adiposity, lipids, cholesterol, inflammation, and growth. We used linear regression to estimate associations of diet quality with [1] phthalates/replacements and [2] metabolic PCs, as well as [3] associations of phthalates/replacements with metabolic PCs. We estimated the proportion of associations between diet quality and metabolic outcomes explained by phthalates/replacements using a causal mediation framework. RESULTS: Overall, every 10-point improvement in AHEI-2010 score was associated with -0.15 (95% CI: -0.27, -0.04) lower adiposity scores, reflecting lower glucose, insulin, C-peptide, leptin, C-reactive protein, but higher adiponectin biomarker levels. Every 10-point increase in diet quality was also associated with 18% (95%CI: 7%, 28%) lower sum of di-2-ethylhexyl terephthalate urinary metabolites (∑DEHTP). Correspondingly, each 18% increase in ∑DEHTP was associated with 0.03 point (95% CI: 0.01, 0.05) higher adiposity PC scores. In mediation analyses, 21% of the inverse relationship between diet quality and adiposity PC scores was explained by lower ∑DEHTP. CONCLUSIONS: The favorable impact of diet quality on maternal adiposity biomarkers may be partially attributed to lower metabolite concentrations of DEHTP, a plasticizer allowed to be used in food packaging materials. |
| The role and limitations of electronic medical records versus patient interviews for determining symptoms, underlying comorbidities, and medication usage for patients with COVID-19
Soto RA , Vahey GM , Marshall KE , McDonald E , Herlihy R , Chun HM , Killerby ME , Kawasaki B , Midgley CM , Alden NB , Tate JE , Staples JE , Team CI . Am J Epidemiol 2024 193 (10) 1442-1450 Electronic medical records (EMRs) are important for rapidly compiling information to determine disease characteristics (eg, symptoms) and risk factors (eg, underlying comorbidities, medications) for disease-related outcomes. To assess EMR data accuracy, agreement between EMR abstractions and patient interviews was evaluated. Symptoms, medical history, and medication use among patients with COVID-19 collected from EMRs and patient interviews were compared using overall agreement (ie, same answer in EMR and interview), reported agreement (yes answer in both EMR and interview among those who reported yes in either), and κ statistics. Overall, patients reported more symptoms in interviews than in EMR abstractions. Overall agreement was high (≥50% for 20 of 23 symptoms), but only subjective fever and dyspnea had reported agreement of ≥50%. The κ statistics for symptoms were generally low. Reported medical conditions had greater agreement with all condition categories (n = 10 of 10) having ≥50% overall agreement and half (n = 5 of 10) having ≥50% reported agreement. More nonprescription medications were reported in interviews than in EMR abstractions, leading to low reported agreement (28%). Discordance was observed for symptoms, medical history, and medication use between EMR abstractions and patient interviews. Investigations using EMRs to describe clinical characteristics and identify risk factors should consider the potential for incomplete data, particularly for symptoms and medications. |
| Extrapolating sentinel surveillance information to estimate national COVID hospital admission rates: A Bayesian modeling approach
Devine O , Pham H , Gunnels B , Reese HE , Steele M , Couture A , Iuliano D , Sachdev D , Alden NB , Meek J , Witt L , Ryan PA , Reeg L , Lynfield R , Ropp SL , Barney G , Tesini BL , Shiltz E , Sutton M , Talbot HK , Reyes I , Havers FP . Influenza Other Respir Viruses 2024 18 (10) e70026 The COVID-19-Associated Hospitalization Surveillance Network (COVID-NET) was established in March 2020 to monitor trends in hospitalizations associated with SARS-CoV-2 infection. COVID-NET is a geographically diverse population-based surveillance system for laboratory-confirmed COVID-19-associated hospitalizations with a combined catchment area covering approximately 10% of the US population. Data collected in COVID-NET includes monthly counts of hospitalizations for persons with confirmed SARS-CoV-2 infection who reside within the defined catchment area. A Bayesian modeling approach is proposed to estimate US national COVID-associated hospital admission rates based on information reported in the COVID-NET system. A key component of the approach is the ability to estimate uncertainty resulting from extrapolation of hospitalization rates observed within COVID-NET to the US population. In addition, the proposed model enables estimation of other contributors to uncertainty including temporal dependence among reported COVID-NET admission counts, the impact of unmeasured site-specific factors, and the frequency and accuracy of testing for SARS-CoV-2 infection. Based on the proposed model, an estimated 6.3 million (95% uncertainty interval (UI) 5.4-7.3 million) COVID-19-associated hospital admissions occurred in the United States from September 2020 through December 2023. Between April 2020 and December 2023, model-based monthly admission rate estimates ranged from a minimum of 1 per 10,000 population (95% UI 0.7-1.2) in June of 2023 to a highest monthly level of 16 per 10,000 (95% UI 13-19) in January 2022. |

BACKGROUND: Despite widespread HIV testing in sub-Saharan Africa, regular testing among at-risk populations is crucial for effective prevention. However, reports increasingly indicate retesting among people living with HIV (PLHIV), a group that would not require additional testing since they would already have received a confirmed diagnosis. We describe the demographic characteristics of PLHIV retesters in Lesotho, report the average number of HIV tests post-diagnosis among PLHIV, and share motivations for retesting. METHODS: In August 2022, a nationally representative cohort in Lesotho participated in a cell phone survey about their HIV status and testing history. Study participants were recruited from a face-to-face survey conducted in 2020, Lesotho Population Based HIV Impact Assessment survey. RESULTS: Of the 1523 participants called, 1111 participants responded (72.9%) and 266 reported living with HIV. We found 18.8% of people living with HIV (PLHIV) reported retesting at least once for HIV, and 58% of PLHIV who reported retesting were likely or very likely to retest for HIV in the coming year. The main reason PLHIV reported retesting was because a health care worker offered the test (61.7%) followed by self-initiated testing to confirm their status (29.1%). Among male PLHIV who had a history of retesting, 92.0% were very likely or likely to retest, compared to only 30.6% of female PLHIV. CONCLUSION: We found almost a fifth of PLHIV in Lesotho reported a history of retesting for HIV, and 58% of PLHIV were likely or very likely to retest for HIV in the coming year. Educating providers and men living with HIV could reduce retesting among PLHIV. |

BACKGROUND: Clusters of invasive group A streptococcal (iGAS) infection, linked to genomically closely related group A streptococcal (GAS) isolates (referred to as genomic clusters), pose public health threats, and are increasingly identified through whole-genome sequencing (WGS) analysis. In this study, we aimed to assess the risk of genomic cluster formation among iGAS cases not already part of existing genomic clusters. METHODS: In this WGS and population-based surveillance study, we analysed iGAS case isolates from the Active Bacterial Core surveillance (ABCs), which is part of the US Centers for Disease Control and Prevention's Emerging Infections Program, in ten US states from Jan 1, 2015, to Dec 31, 2019. We included all residents in ABCs sites with iGAS infections meeting the case definition and excluded non-conforming GAS infections and cases with whole-genome assemblies of the isolate containing fewer than 1·5 million total bases or more than 150 contigs. For iGAS cases we collected basic demographics, underlying conditions, and risk factors for infection from medical records, and for isolates we included emm types, antimicrobial resistance, and presence of virulence-related genes. Two iGAS cases were defined as genomically clustered if their isolates differed by three or less single-nucleotide variants. An iGAS case not clustered with any previous cases at the time of detection, with a minimum trace-back time of 1 year, was defined as being at risk of cluster formation. We monitored each iGAS case at risk for a minimum of 1 year to identify any cluster formation event, defined as the detection of a subsequent iGAS case clustered with the case at risk. We used the Kaplan-Meier method to estimate the cumulative incidence of cluster formation events over time. We used Cox regression to assess associations between features of cases at risk upon detection and subsequent cluster formation. We developed a random survival forest machine-learning model based on a derivation cohort (random selection of 50% of cases at risk) to predict cluster formation risk. This model was validated using a validation cohort consisting of the remaining 50% of cases at risk. FINDINGS: We identified 2764 iGAS cases at risk from 2016 to 2018, of which 656 (24%) formed genomic clusters by the end of 2019. Overall, the cumulative incidence of cluster formation was 0·057 (95% CI 0·048-0·066) at 30 days after detection, 0·12 (0·11-0·13) at 90 days after detection, and 0·16 (0·15-0·18) at 180 days after detection. A higher risk of cluster formation was associated with emm type (adjusted hazard ratio as compared with emm89 was 2·37 [95% CI 1·71-3·30] for emm1, 2·72 [1·82-4·06] for emm3, 2·28 [1·49-3·51] for emm6, 1·47 [1·05-2·06] for emm12, and 2·21 [1·38-3·56] for emm92), homelessness (1·42 [1·01-1·99]), injection drug use (2·08 [1·59-2·72]), residence in a long-term care facility (1·78 [1·29-2·45]), and the autumn-winter season (1·34 [1·14-1·57]) in multivariable Cox regression analysis. The machine-learning model stratified the validation cohort (n=1382) into groups at low (n=370), moderate (n=738), and high (n=274) risk. The 90-day risk of cluster formation was 0·03 (95% CI 0·01-0·05) for the group at low risk, 0·10 (0·08-0·13) for the group at moderate risk, and 0·21 (0·17-0·25) for the group at high risk. These results were consistent with the cross-validation outcomes in the derivation cohort. INTERPRETATION: Using population-based surveillance data, we found that pathogen, host, and environment factors of iGAS cases were associated with increased likelihood of subsequent genomic cluster formation. Groups at high risk were consistently identified by a predictive model which could inform prevention strategies, although future work to refine the model, incorporating other potential risk factors such as host contact patterns and immunity to GAS, is needed to improve its predictive performance.

| Perspectives of healthcare providers around providing family planning services to women living with HIV attending six HIV treatment clinics in Lusaka, Zambia
Medley A , Aholou T , Pals S , Harris TG , Senyana B , Braaten M , Kasonde P , Chisenga T , Mwila A , Mweebo K , Tsiouris F . AIDS Care 2024 1-11 ABSTRACTWhile international guidelines recommend integration of family planning (FP) and HIV services, limited research has been done to explore how healthcare providers perceive the feasibility and utility of integrated services. To address this gap, we administered a standardized questionnaire to 85 providers from 6 HIV clinics in Lusaka, Zambia, before (April-May 2018) and after (May-June 2019) implementing an enhanced model of FP/HIV service integration. We tested for differences in FP knowledge, attitudes and practices between the two time periods with tests appropriate for paired observations. The proportion of providers self-reporting direct provision of contraceptives increased significantly for several methods including oral contraceptives (14% vs. 26%, p = 0.03), injectables (9% vs. 25%, p < 0.001), implants (2% vs. 13%, p = 0.007) and intra-uterine devices (2% vs. 13%, p = 0.007). In-depth interviews were also conducted post-integration with 109 providers to solicit their feedback on the benefits and challenges of offering integrated services. While providers were highly supportive of integrated services, they identified several challenges including widespread belief in FP myths among female clients, the need to consult a male partner prior to starting FP, lack of trained staff and space, and frequent stockouts of contraceptives and equipment. Addressing these challenges will be critical in designing future services. |
| The use of the CDC Preventive Health and Health Services Block Grant to address social determinants of health to advance health equity
Frazier CM , Mumford K , McMillan H , Carlin M , Peterman E , Lindan K . J Public Health Manag Pract 2024 OBJECTIVE: State public health departments use federal funding to examine and address social determinants of health (SDOH) within their communities to improve health and advance health equity. Yet, most federal funding is categorical (ie, funding used for a specific program or narrow purpose), which can create barriers to addressing social and structural drivers of inequity. The Preventive Health and Health Services Block Grant (PHHS Block Grant) is a flexible funding mechanism that provides health departments the latitude to identify and fund initiatives that address local public health needs. It is unclear, however, to what extent health departments use this flexible resource to incorporate SDOH into their programs. DESIGN: Cross-sectional, descriptive analysis of state health department PHHS Block Grant program administrative data. SETTING: This study examined PHHS Block Grant budgets and workplans for the federal Fiscal Year 2021 to assess whether state health departments aligned their grant-funded program with the national objectives associated with the Healthy People 2030 SDOH Framework. PARTICIPANTS: Forty-seven states and the District of Columbia were included in this study. MAIN OUTCOME MEASURES: Percent of states that used PHHS Block Grant funds to address SDOH; proportion of funding allocated to address SDOH; percentage of programs that addressed SDOH. RESULTS: Three-fourths (75%) of states allocated funds to 97 programs aligning with at least 1 Healthy People 2030 SDOH-related objective. Fifty of the programs were fully or primarily funded by the PHHS Block Grant. Results also show that as the states' PHHS Block Grant funding level increased so did the percent of states that allocated funding toward SDOH programs. CONCLUSION: This study shows that state health departments are using the PHHS Block Grant to address SDOH, and that the grant plays an important funding role for these programs. States are incorporating the grant into their funding strategies to address SDOH. |
| "But then that's another barrier": A qualitative study of parent and provider perspectives on rural versus urban disparities in adolescent vaccination
Brewer SE , Cataldi JR , Perreira C , Nederveld A , Fisher MP , Furniss A , Williams C , O'Leary ST , Dempsey AF . Vaccine 2024 42 (26) 126456 PURPOSE: Vaccination rates are significantly lower among adolescents living in rural areas compared to those living in urban areas. The objective of this study was to understand the factors contributing to disparities in vaccination between adolescents in rural compared to urban areas. METHODS: Semi-structured qualitative interviews were conducted with parents and providers in 16 rural and 4 urban counties of Colorado. Interview questions followed the socioecological model of health and addressed personal, interpersonal, community, and environment/structural barriers and facilitators that impact adolescent vaccination rates. Qualitative content analysis with a directed content analysis approach was used. Urban and rural interviews were compared to identify barriers unique to rural communities. FINDINGS: Reported barriers included lack of vaccine access at primary care, lack of routine preventive care utilization, the need to take off time from work and school, and misinformation about vaccines. Barriers that were unique to rural communities included structural barriers such as lack of evening and weekend appointments, providers not stocking vaccines, short provider tenures, and costs; logistical barriers such as the need for multiple visits to multiple locations and distance and travel time; and beliefs and behaviors such as an overreliance on sports physicals (in lieu of preventive visits) and natural lifestyle cultures. CONCLUSIONS: There are unique challenges to adolescent vaccination in rural areas that contribute to fewer adolescents receiving their recommended vaccines. Addressing structural barriers may address this disparity. |
| Health facility capacity and health-care worker knowledge, attitudes, and practices of hepatitis B vaccine birth-dose and maternal tetanus-diphtheria vaccine administration in Nigeria: A baseline assessment
Uba BV , Mohammed Y , Nwokoro UU , Fadahunsi R , Adewole A , Ugbenyo G , Simple E , Wisdom MO , Waziri NE , Michael CA , Okeke LA , Kanu F , Ikwe H , Sandhu HS , Asekun A , Tohme RA , Freeland C , Minta A , Bashir SS , Isa A , Vasumu JJ , Bahuli AU , Ugwu GO , Obi EI , Ismail BA , Okposen BB , Bolu OO , Shuaib F . Ann Afr Med 2024 BACKGROUND: Hepatitis B virus (HBV) and neonatal tetanus infections remain endemic in Nigeria despite the availability of safe, effective vaccines. We aimed to determine health facilities' capacity for hepatitis B vaccine birth dose (HepB-BD) and maternal tetanus-diphtheria (Td) vaccination and to assess knowledge, attitudes, and practices of HepB-BD and maternal Td vaccine administration among health facility staff in Nigeria. MATERIALS AND METHODS: This was a cross-sectional study assessing public primary and secondary health facilities in Adamawa and Enugu States. A multistage sampling approach was used to select 40 facilities and 79 health-care workers (HCWs) from each state. A structured facility assessment tool and standardized questionnaire evaluated facility characteristics and HCW knowledge, attitudes, and practices related to HepB-BD and maternal Td vaccination. Frequencies and proportions were reported as descriptive statistics. RESULTS: The survey of 80 facilities revealed that 73.8% implemented HepB-BD and maternal Td vaccination policies. HepB-BD was administered within 24 h of birth at 61.3% of facilities and at all times at 57.5%. However, administration seldom occurred in labor and delivery (35%) or maternity wards (16.3%). Nearly half of the facilities (46.3%) had HCWs believing there were contraindications to HepB-BD vaccination. Among 158 HCWs, 26.5% believed tetanus could be transmitted through unprotected sex, prevented by vaccination at birth (46.1%), or by avoiding sharing food and utensils. 65% of HCWs knew HBV infection had the worst outcome for newborns. CONCLUSIONS: The limited implementation of national policies on HepB-BD and maternal Td vaccination, coupled with knowledge gaps among HCWs, pose significant challenges to timely vaccination, necessitating interventions to address these gaps. |
| Meeting report: Controlled human influenza virus infection model studies: Current status and future directions for innovation
Lane MC , Luke CJ , Bresee J , Dugan VG , Post DJ , Schafer J , Roberts PC , Wentworth DE , Ison MG . Influenza Other Respir Viruses 2024 18 (10) e13358 On November 13-14, 2023, the National Institute of Allergy and Infectious Diseases (NIAID) in partnership with the Task Force for Global Health, Flu Lab, the Canadian Institutes of Health Research, and the Centers for Disease Control and Prevention convened a meeting on controlled human influenza virus infection model (CHIVIM) studies to review the current research landscape of CHIVIM studies and to generate actionable next steps. Presentations and panel discussions highlighted CHIVIM use cases, regulatory and ethical considerations, innovations, networks and standardization, and the utility of using CHIVIM in vaccine development. This report summarizes the presentations, discussions, key takeaways, and future directions for innovations in CHIVIMs. Experts agreed that CHIVIM studies can be valuable for the study of influenza infection, immune response, and transmission. Furthermore, they may have utility in the development of vaccines and other medical countermeasures; however, the use of CHIVIMs to de-risk clinical development of investigational vaccines should employ a cautious approach. Endpoints in CHIVIM studies should be tailored to the specific use case. CHIVIM studies can provide useful supporting data for vaccine licensure but are not required and do not obviate the need for the conduct of field efficacy trials. Future directions in this field include the continued expansion of capacity to conduct CHIVIM studies, development of a broad panel of challenge viruses and assay reagents and standards that can be shared, streamlining of manufacturing processes, the exploration of targeted delivery of virus to the lower respiratory tract, efforts to more closely replicate natural influenza disease in CHIVIM, alignment on a definition of breadth to facilitate development of more broadly protective/universal vaccine approaches, and continued collaboration between stakeholders. |

Lancet 2024 404 (10462) 1547-1559 BACKGROUND: Respiratory syncytial virus vaccines first recommended for use during 2023 were efficacious against lower respiratory tract disease in clinical trials. Limited real-world data regarding respiratory syncytial virus vaccine effectiveness are available. To inform vaccine policy and address gaps in evidence from the clinical trials, we aimed to assess the effectiveness against respiratory syncytial virus-associated hospitalisations and emergency department encounters among adults aged at least 60 years. METHODS: We conducted a test-negative design analysis in an electronic health records-based network in eight states in the USA, including hospitalisations and emergency department encounters with respiratory syncytial virus-like illness among adults aged at least 60 years who underwent respiratory syncytial virus testing from Oct 1, 2023, to March 31, 2024. Respiratory syncytial virus vaccination status at the time of the encounter was derived from electronic health record documentation, state and city immunisation registries, and, for some sites, medical claims. Vaccine effectiveness was estimated by immunocompromise status, comparing the odds of vaccination among respiratory syncytial virus-positive case patients and respiratory syncytial virus-negative control patients, and adjusting for age, race and ethnicity, sex, calendar day, social vulnerability index, number of underlying non-respiratory medical conditions, presence of respiratory underlying medical conditions, and geographical region. FINDINGS: Among 28 271 hospitalisations for respiratory syncytial virus-like illness among adults aged at least 60 years without immunocompromising conditions, vaccine effectiveness was 80% (95% CI 71-85) against respiratory syncytial virus-associated hospitalisations, and vaccine effectiveness was 81% (52-92) against respiratory syncytial virus-associated critical illness (ICU admission or death, or both). Among 8435 hospitalisations for respiratory syncytial virus-like illness among adults with immunocompromising conditions, vaccine effectiveness was 73% (48-85) against associated hospitalisation. Among 36 521 emergency department encounters for respiratory syncytial virus-like illness among adults aged at least 60 years without an immunocompromising condition, vaccine effectiveness was 77% (70-83) against respiratory syncytial virus-associated emergency department encounters. Vaccine effectiveness estimates were similar by age group and product type. INTERPRETATION: Respiratory syncytial virus vaccination was effective in preventing respiratory syncytial virus-associated hospitalisations and emergency department encounters among adults aged at least 60 years in the USA during the 2023-24 respiratory syncytial virus season, which was the first season after respiratory syncytial virus vaccine was approved.

Circulating vaccine-derived polioviruses (cVDPVs) can emerge and lead to outbreaks of paralytic polio as well as asymptomatic transmission in communities with a high percentage of undervaccinated children. Using data from the World Health Organization Polio Information System and Global Polio Laboratory Network, this report describes global polio outbreaks due to cVDPVs during January 2023-June 2024 and updates previous reports. During the reporting period, 74 cVDPV outbreaks were detected in 39 countries or areas (countries), predominantly in Africa. Among these 74 cVDPV outbreaks, 47 (64%) were new outbreaks, detected in 30 (77%) of the 39 countries. Three countries reported cVDPV type 1 (cVDPV1) outbreaks and 38 countries reported cVDPV type 2 (cVDPV2) outbreaks; two of these countries reported cocirculating cVDPV1 and cVDPV2. In the 38 countries with cVDPV2 transmission, 70 distinct outbreaks were reported. In 15 countries, cVDPV transmission has lasted >1 year into 2024. In Nigeria and Somalia, both countries with security-compromised areas, persistent cVDPV2 transmission has spread to neighboring countries. Delayed implementation of outbreak response campaigns and low-quality campaigns have resulted in further international spread. Countries can control cVDPV outbreaks with timely allocation of resources to implement prompt, high-quality responses after outbreak confirmation. Stopping all cVDPV transmission requires effectively increasing population immunity by overcoming barriers to reaching children. |
| Coverage with selected vaccines and exemption rates among children in kindergarten - United States, 2023-24 School Year
Seither R , Yusuf OB , Dramann D , Calhoun K , Mugerwa-Kasujja A , Knighton CL , Kriss JL , Miller R , Peacock G . MMWR Morb Mortal Wkly Rep 2024 73 (41) 925-932 In the United States, states and local jurisdictions set vaccination requirements for school attendance, conditions and procedures for exemptions from these requirements, grace periods for submitting documentation, and provisional enrollment for students who need more time to be vaccinated. States annually report data to CDC on the number of children in kindergarten who meet, are exempt from, or are in the process of meeting requirements. Data reported by 49 states and the District of Columbia (DC) for the 2023-24 school year were used for national- and state-level estimates of the following measures: complete vaccination with required doses of measles, mumps, and rubella vaccine (MMR), diphtheria, tetanus, and acellular pertussis vaccine (DTaP), poliovirus vaccine (polio), and varicella vaccine (VAR); exemptions from vaccination; and school attendance while meeting requirements. The 2023-24 kindergarten class became age-eligible to complete most state-required vaccinations during the COVID-19 pandemic, after schools had returned to routine in-person learning. Compared with approximated national coverage levels across all reported vaccines for the 2019-20 (95%) and 2022-23 (93%) school years, coverage dropped below 93% for the 2023-24 school year, ranging from 92.3% for DTaP to 92.7% for MMR. Exemptions increased to 3.3%, compared with those during the 2022-23 (3.0%) and 2021-22 school years (2.6%). Coverage with MMR, DTaP, polio, and VAR decreased in 35, 32, 33, and 36 jurisdictions, respectively, compared with the 2022-23 school year. Exemptions increased in 41 jurisdictions, with 14 reporting that >5% of kindergartners had an exemption from one or more vaccine. Efforts by health departments, schools, and providers are needed to ensure that students begin school fully vaccinated. |
| Relative effectiveness and immunogenicity of quadrivalent recombinant influenza vaccine versus egg-based inactivated influenza vaccine among adults aged 18-64 years: Results and experience from a randomized, double-blind trial

Open Forum Infect Dis 2024 11 (10) ofae559 BACKGROUND: Immunogenicity studies suggest that recombinant influenza vaccine (RIV) may provide better protection against influenza than standard-dose inactivated influenza vaccines (SD IIV). This randomized trial evaluated the relative vaccine effectiveness (VE) and immunogenicity of RIV versus SD IIV in frontline workers and students aged 18-64 years. METHODS: Participants were randomized to receive RIV or SD IIV and followed for reverse-transcription polymerase chain reaction (RT-PCR)-confirmed influenza during the 2022-2023 influenza season. Sera were collected from a subset of participants before and at 1 and 6 months postvaccination and tested by hemagglutination inhibition for A/H1N1, A/H3N2, B/Yamagata, and B/Victoria and against cell-grown vaccine reference viruses for A/H1N1 and A/H3N2. RESULTS: Overall, 3988 participants were enrolled and vaccinated (25% of the trial sample size goal); RT-PCR-confirmed influenza occurred in 20 of 1963 RIV recipients and 28 of 1964 SD IIV recipients. Relative VE was 29% (95% confidence interval [CI], -26% to 60%). In the immunogenicity substudy (n = 118), the geometric mean titer ratio (GMTR) comparing RIV to SD IIV at 1 month was 2.3 (95% CI, 1.4-3.7) for cell-grown A/H1N1, 2.1 (95% CI, 1.3-3.4) for cell-grown A/H3N2, 1.1 (95% CI, .7-1.6) for B/Victoria, and 1.4 (95% CI, .9-2.0) for B/Yamagata. At 6 months, GMTRs were >1 against A/H1N1, A/H3N2, and B/Yamagata. CONCLUSIONS: Relative VE of RIV compared to SD IIV did not reach statistical significance, but RIV elicited more robust humoral immune responses to 2 of 4 vaccine viruses at 1 month and 3 of 4 viruses at 6 months after vaccination, suggesting possible improved and sustained immune protection from RIV.

| Symptoms six weeks after COVID-19 are reduced among US health care personnel receiving additional vaccine doses during the Omicron period, December 2021-April 2022
Mohr NM , Plumb ID , Santos León E , Pinckney M , Harland KK , Krishnadasan A , Hoth KF , Rwamwejo F , Haran JP , Briggs-Hagen M , Kontowicz E , Talan DA . Open Forum Infect Dis 2024 11 (10) ofae545 BACKGROUND: The objective of this study was to test the hypothesis that subsequent doses of the coronavirus disease 2019 (COVID-19) vaccine are associated with lower incidence of COVID-19-like symptoms at 6 weeks after infection. METHODS: This study was a case-control analysis of health care personnel in an ongoing multicenter COVID-19 vaccine effectiveness study. We enrolled participants at the time of COVID-19-like symptoms between December 19, 2021, and April 27, 2022, which corresponded to the early Omicron-predominant period after original monovalent severe acute respiratory syndrome coronavirus 2 additional vaccination doses became available. Our outcome was self-reported symptoms completed 6 weeks after the onset of symptoms. RESULTS: We enrolled 2478 participants, of whom 1422 (57%) had COVID-19. The prevalence of symptoms at 6 weeks was 26% (n = 373) in those with COVID-19 and 18% (n = 195) in those without COVID-19. Fatigue (11%) and difficulty sleeping (7%) were most strongly associated with COVID-19. A total of 1643 (66%) participants received a subsequent vaccine dose (after the primary series). Participants with COVID-19 who had received a subsequent vaccination had lower odds of symptoms at 6 weeks (adjusted odds ratio [aOR], 0.55; 95% CI, 0.43-0.70), but this relationship was not observed in those without COVID-19 (aOR, 0.87; 95% CI, 0.59-1.29). CONCLUSIONS: Health care personnel who received subsequent doses of original monovalent COVID-19 vaccine had a lower prevalence of symptoms at 6 weeks than those that did not. |
| Data quality in state registry reports of medical cannabis patients in the United States
Boehnke KF , Sinclair R , Gordon F , Roehler DR , Smith T , Hoots B . Am J Public Health 2024 114 S685-s693 Objectives. To investigate characteristics of data reported in US medical cannabis registries across states. Methods. Data included 2021 medical cannabis registry reports from 34 states, Puerto Rico, and the District of Columbia (hereafter, states) with active medical cannabis programs. The data from the reports were manually coded into domains and subcategories, including information related to patients (e.g., number, demographics), authorizing clinicians, sales (e.g., content, revenue), license tracking, and health and safety outcomes. Results. Among 36 states, 97% reported total patient number and 75% reported number of authorizing clinicians. Least reported subcategories included patient race/ethnicity (8%), adverse events (11%), therapeutic benefits (6%), and product recalls (6%). States that recently legalized medical cannabis (2013-2018) reported a higher number of subcategories overall, with a median of 11 versus 8 for early adopting states (1996-2012). More medical-use states reported data on authorizing clinicians compared with nonmedical adult-use states but were otherwise similar. Conclusions. Medical cannabis state registries generally reported data on consumers, clinicians, and sales rather than health and safety outcomes. More comprehensive and uniform medical cannabis public health surveillance is needed. (Am J Public Health. 2024;114(S8):S685-S693. https://doi.org/10.2105/AJPH.2024.307728). |
| Rates of fall injuries across three claims databases, 2019
Miller GF , Dunphy C , Haddad YK , Chen J , Alic A , Thomas K , Wolkin AF . Inj Prev 2024 INTRODUCTION: In 2021, among all age groups, falls ranked as the third leading cause of unintentional injury death in the USA. Unlike fatal data, which rely on death certificates as the gold standard, there is not a gold standard for non-fatal data. Non-fatal falls data are often based on insurance claims or administrative billing data. The purpose of our study is to compare three claims databases to estimate rates of unintentional fall-related hospitalisations in 2019, the most recent year of available data across the three sources. METHODS: Three databases were used to produce incidence rates of fall-related hospitalisations for the year 2019: (1) Merative MarketScan research databases, (2) Centers for Medicare and Medicaid Services (CMS) data and (3) Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample. Inpatient falls were identified using International Classification of Diseases, 10th Revision, Clinical Modification codes. Incidence rates per 100 000 people were then produced across all three datasets by payer type. Unadjusted incidence rate ratios were estimated with corresponding 95% CIs. RESULTS: There were wide disparities among fall rates between the three datasets by payer type. HCUP had the highest rate of falls among Medicare (1087.6 per 100 000) and commercial enrollees (74.7 per 100 000), while CMS had the highest rates of falls among Medicaid enrollees (148.0 per 100 000). CONCLUSIONS: This study shows wide variation in fall hospitalisation rates based on the claims data used to estimate rates. This study suggests that database selection is an important consideration when determining incidence of non-fatal falls. |

Mark JA , Henry A , Moreland B , Dobash D , Bergen G . J Appl Gerontol 2024 7334648241289933 Objectives: Reducing fall risk requires older adults (age 65+) to adopt effective prevention strategies. This study has three aims: 1) understand Stage of Change (SOC) for three fall prevention strategies; 2) determine strategies older adults' use; and 3) understand which characteristics relate to readiness to take action. Methods: A survey of 1063 older adults assessed fall risk, SOC, and use of fall prevention strategies. Data analysis included descriptive statistics and regression analysis. Results: The most common SOC for older adults by strategy was action for overall fall prevention (61%), contemplation for medication management (45%), and preparation and action for strength/balance (29% each). Believing falls are preventable was most strongly related to being in a Change stage (e.g., action, maintenance) for overall fall prevention (Risk Ratio: 1.4, 95% CI: 1.1, 1.7). Discussion: Health promotion can focus on increasing knowledge of evidence-based fall prevention strategies to encourage older adults to take action. |
| Lifetime history of head or traumatic brain injury before age 9 and school outcomes: Results from the adolescent brain cognitive development study
Waltzman D , Haarbauer-Krupa J , Daugherty J , Sarmiento K , Yurgelun-Todd DA , McGlade EC . J Sch Health 2024 BACKGROUND: Limited information about school outcomes among children (especially early childhood) with lifetime history of head injury, including traumatic brain injury (TBI), may inhibit efforts to support their academics and physical and mental health. METHODS: Baseline data (2016-2018) from the Adolescent Brain Cognitive Development (ABCD) study were analyzed to describe associations between parent-proxy reported lifetime history of head injury or TBI before age 9 and school outcomes and behavioral challenges among 9- and 10-year-old children. RESULTS: Having a lifetime history of head injury before age 9 was associated with increased odds of parent-perceived poor school performance (adjusted odds ratio [AOR] = 1.44, 95% confidence interval [CI] = 1.14-1.81), a drop in grades (AOR = 1.28, 95%CI = 1.06-1.54), recent receipt of detentions or suspensions (AOR = 1.29, 95%CI = 1.02-1.65), and receipt of special educational services (AOR = 1.23, 95%CI = 1.08-1.41). Of those with a lifetime history of head injury, males displayed poorer school outcomes and greater behavioral challenges than females. Similar associations were observed between lifetime history of TBI before age 9 and worse school outcomes, with males continuing to demonstrate stronger associations. CONCLUSIONS: These findings underscore the importance of screening for history of head injury and TBI and providing training for school professionals to help ensure students with a history of head or traumatic brain injury have appropriate supports in place. |
| Candida auris MIC testing by EUCAST and CLSI broth microdilution, and gradient diffusion strips; to be or not to be amphotericin B resistant?
Arendrup MC , Lockhart SR , Wiederhold N . Clin Microbiol Infect 2024 OBJECTIVES: Reported amphotericin B resistance rates for Candida auris vary considerably. This may reflect clinically relevant differences in susceptibility, technical issues with testing or adoption of a clinical breakpoint (BP) that bisects the wild-type population. We compared reference methods and two gradient diffusion strips using a shared C. auris strain collection. METHODS: Forty C. auris strains from nine US states and ≥3 clades were included. Fourteen MIC data sets were generated using EUCAST E.Def 7.4, CLSI M27Ed4, Etest and MTS (Liofilchem) strip MICs. MICs ≤1 mg/L were classified as susceptible. RESULTS: EUCAST and CLSI amphotericin B MIC testing were robust across included method variables. The modal MIC was 1 mg/L, distributions unimodal and narrow with similar GM-MICs (0.745-1.072); however, susceptibility classification varied (0-28% resistance). Gradient diffusion strip testing resulted in wider and bimodal distributions for 8/9 data sets. If adopting, per manufacturer's protocol, double inoculation for the Etest method, the modal MIC increased to 2-4 mg/L and resistance rates to 45-63% versus 25-30% with the single inoculation. The EUCAST, CLSI, Etest and MTS strip MICs correlated to the OD of drug-free control EUCAST wells suggesting that some isolates grew better than others and that this was associated with MIC. CONCLUSIONS: The EUCAST and CLSI MIC results were in close agreement, whereas the strip test showed wider and bimodal distributions with reader to reader and centre to centre variation. Our study adds to the concern for commercial MIC testing of amphotericin B against C. auris and suggest the current breakpoint leads to random susceptibility classification. |

Int J Infect Dis 2024 107264 BACKGROUND: We examined the added value of serologic testing for estimating influenza virus infection incidence based on illness surveillance with molecular testing versus periodic serologic testing. METHODS: Pregnant persons unvaccinated against influenza at <28 weeks gestation were enrolled before the 2017 and 2018 influenza seasons in Peru and Thailand. Blood specimens were collected at enrollment and ≤14 days postpartum for testing by hemagglutination inhibition assay for antibodies against influenza reference viruses. Seroconversion was defined as a ≥4-fold rise in antibody titers from enrollment to postpartum with the second specimen's titer of ≥40. Throughout pregnancy, participants responded to twice weekly surveillance contacts asking about influenza vaccination and influenza-like symptoms (ILS). A mid-turbinate swab was collected with each ILS episode for influenza real-time reverse transcription PCR (rRT-PCR). RESULTS: Of 1,466 participants without evidence of influenza vaccination during pregnancy, 296 (20.2%) had evidence of influenza virus infections. Fifteen (5.1%) were detected by rRT-PCR only, 250 (84.4%) by serologic testing only, and 31 (10.5%) by both methods. CONCLUSIONS: Influenza virus infections during pregnancy occurred in 20% of cohort participants; >80% were not detected by a broad illness case definition coupled with rRT-PCR. |

Hwang CS , Montgomery MP , Diaz Munoz DI , Yin S , Teshale EH , Bocour A . J Public Health Manag Pract 2024 CONTEXT: Laboratory-based hepatitis C virus (HCV) clearance cascades are an important tool for health departments to track progress toward HCV elimination, but a laboratory-based definition of HCV clearance has not yet been validated. OBJECTIVE: To compare agreement between a laboratory-based HCV clearance definition with a clinical cure definition. DESIGN: Observational. SETTING: New York City Department of Health and Mental Hygiene HCV surveillance system data and New York City hepatitis C linkage-to-care program data. PARTICIPANTS: Linkage-to-care program participants who were diagnosed with hepatitis C and enrolled in the linkage-to-care program from July 1, 2016, through June 30, 2020. MAIN OUTCOME MEASURE: Percent agreement between a laboratory-based HCV clearance definition (surveillance system) and a clinical cure definition (program data). RESULTS: Among 591 program participants with known treatment outcome, the laboratory-based HCV clearance definition and clinical cure definition were concordant in 573 cases (97%). CONCLUSIONS: A laboratory-based HCV clearance definition based on public health surveillance data can be a reliable source for monitoring HCV elimination. |
| Evaluation of a multiplex real-time PCR targeting the β-tubulin gene for the detection and differentiation of Sporothrix schenckii and Sporothrix brasiliensis
López LF , Gade L , Litvintseva AP , Sexton DJ . Microbiol Spectr 2024 e0116224
Sporothrix sp. is a thermally dimorphic genus of fungi known to cause subacute or chronic subcutaneous lesions in humans and animals and is the cause of increasing public health concern due to spread of feline-associated cases. Here, we adapted and evaluated a recently described real-time PCR assay targeting the β-tubulin gene to rapidly detect and differentiate two related species, S. schenckii and S. brasiliensis. The assay was tested with 55 S. brasiliensis, 19 S. schenckii, and 85 isolates from other clinically relevant fungi, and showed 100% concordance with reference identification methods. The assay showed high analytical sensitivity with a limit of detection of 1 pg of DNA per microliter of sample for both targets. The assay was further evaluated with 11 fresh and 17 formalin-fixed, paraffin-embedded (FFPE) tissues. This multiplex real-time PCR assay successfully detected the DNA from both S. brasiliensis and S. schenckii isolates as well as S. schenckii from fresh and FFPE tissues. Our results demonstrate this assay performs well and could be a helpful molecular tool to support rapid species identification in cultures and primary specimens.IMPORTANCEHaving available molecular tools to identify and differentiate closely related species will allow clinical, veterinarians, and public health labs to provide diagnostic results with accuracy and short turnaround time for the routine and outbreak response activities. |
| Regional differences in autism and intellectual disability risk associated with cesarean section delivery
Bilder DA , Sullivan S , Hughes MM , Dalton S , Hall-Lande J , Nicholls C , Bakian AV . Autism Res 2024 Prior epidemiological studies investigating the association between delivery mode (i.e., vaginal birth and cesarean section [C-section]) and autism spectrum disorder (ASD) and intellectual disability (ID) risk have reported mixed findings. This study examined ASD and ID risks associated with primary and repeat C-section within diverse US regions. During even years 2000-2016, 8-years-olds were identified with ASD and/or ID and matched to birth records [ASD only (N = 8566, 83.6% male), ASD + ID (N = 3445, 79.5% male), ID only (N = 6158, 60.8% male)] using the Centers for Disease Control and Prevention's Autism and Developmental Disabilities Monitoring Network methodology. The comparison birth cohort (N = 1,456,914, 51.1% male) comprised all births recorded in the National Center for Health Statistics corresponding to birth years and counties in which surveillance occurred. C-section rates in the birth cohort demonstrated significant regional variation with lowest rates in the West. Overall models demonstrate increased odds of disability associated with primary and repeat C-section. Adjusted models, stratified by region, identified significant variability in disability likelihood associated with repeat C-section: increased odds occurred for all case groups in the Southeast, for ASD only and ID only in the Mid-Atlantic, and no case groups in the West. Regional variability in disability risk associated with repeat C-section coincides with differences in birth cohorts' C-section rates. This suggests increased likelihood of disability is not incurred by the procedure itself, but rather C-section serves as a proxy for exposures with regional variability that influence fetal development and C-section rates. |
| Low social support is associated with postpartum depression symptoms among Illinois postpartum women
Holicky A , Horne A , Bennett AC . Birth 2024 BACKGROUND: Postpartum depression (PPD) occurs after delivery, with severity and onset varying by individual. Women with low social support may be at higher risk for PPD. This study examined the association between social support and self-reported postpartum depression symptoms (PDS) among Illinois postpartum women. METHODS: Using 2016-2020 data from the Illinois Pregnancy Risk Assessment Monitoring System (PRAMS) (n = 5886), instrumental support (physical, hands-on support) and partner emotional support were each categorized as high/low and were combined in a composite measure (high = high on both types, moderate = high on one type, and low = low on both types). PDS were self-reported. Crude and adjusted odds ratios (aOR) and 95% confidence intervals (CI) were calculated using logistic regression. RESULTS: Overall, 9.6% (95% CI = 8.8-10.4) of Illinois postpartum women experienced PDS. Of Illinois postpartum women, 63.5% (95% CI = 62.1-64.9) had high composite support, 29.3% (95% CI = 28.0-30.6) had moderate composite support, and 7.1% (95% CI = 6.4-7.9) had low composite support. After adjustment for maternal characteristics, instrumental support, partner emotional support, and a composite measure of support were each significantly associated with PDS. Compared to women with high composite support, women with low composite support had six times the odds of PDS (aOR = 6.1, 95% CI = 4.5-8.2), and women with moderate composite support had nearly three times the odds of PDS (aOR = 2.7, 95% CI = 2.2-3.4). CONCLUSION: PDS was associated with instrumental support, partner emotional support, and a composite measure of support in Illinois postpartum women. This suggests the importance of addressing social support for postpartum individuals. |
| Behavioral design strategies improve healthy food sales in a military cafeteria
Kimmons J , Nugent NB , Harris D , Lee SH , Kompaniyets L , Onufrak S . Am J Health Promot 2024 8901171241293369 PURPOSE: This study examined the use of behavioral design strategies to improve healthier food sales. DESIGN: A quasi-experimental, one-group, repeated measures design examined changes in food sales following behavioral design adjustments. SETTING: United States military base hospital dining facility. SUBJECTS: U.S. military service members, retirees, and civilian employees. INTERVENTION: Behavioral design changes included placement, layout, messaging, default healthy bundling, a stoplight rating system, strategic positioning of healthy items on menu boards, and an increase in healthier snacks. MEASURES: Food sales were assessed by point-of-sales data. ANALYSIS: T-tests examined total sales of each food adjusted weekly between baseline and intervention and intervention and post-intervention. 16 food items targeted by the intervention were examined. Weekly food sales were calculated for the 18-week baseline, 18-week intervention, and 9-week post-intervention. Further, analysis estimated negative binomial models for food item sales. RESULTS: The hospital dining facility served 600 to 900 meals per day. Weekly foods sales decreased during the intervention for desserts, cooked starches, hummus, and yogurt (P < 0.01). Sales increased during the intervention for fruit cups, cooked vegetables, vegetable and turkey burgers, grilled chicken, packaged salads, French fries, hamburgers, and hot dogs (P < 0.02). CONCLUSION: This study demonstrates that a mixture of behavioral design strategies can be operationalized with reasonable fidelity and can lead to increases in the sales of some healthy foods in military worksites. |
| Work-related factors associated with psychological distress among grocery workers during the COVID-19 pandemic
Payne J , Esquivel NS , Strazza K , Viator C , Durocher B , Sivén J , Flynn MA , Menéndez CC , Kaur H . AJPM Focus 2024 3 (6) 100272 INTRODUCTION: During the COVID-19 pandemic, grocery workers experienced new (in addition to existing) work-related stressors that put them at risk for psychological distress. This study uses the job demands-resources theory to identify and describe the job demands and resources associated with grocery worker distress. METHODS: This study analyzed data from 75 90-minute interviews focusing on grocery workers' experiences during the COVID-19 pandemic. During the interviews, participants also answered questions associated with the Patient Health Questionnaire 4, a validated measure of psychological distress. RESULTS: Overall, the study found that 36% of study participants exhibited mild to severe psychological distress at the time of their interviews, and a greater proportion of young, female, and White participants reported mild to severe psychological distress than did participants in other subgroups. Qualitative data suggest that the prevalence of psychological distress among participants was likely higher at the beginning of the pandemic and resulted from fear of SARS-CoV-2 exposure, conflict with customers, workplace discrimination, increased workload, and designation as an essential worker. Although about half of the participants in the sample said that their employers provided support to improve workers' mental health, the interviews suggest that more could be done. CONCLUSIONS: These findings may lead to opportunities to improve worker well-being during the COVID-19 pandemic and to prepare for future public health emergencies. Proposed strategies include implementing public health measures as advised by infectious disease experts; offering information and training; providing sick leave, long-term hazard pay, higher wages, and mental health benefits; and better distribution of workloads. |
| A longitudinal pre-post study: An evaluation of the Department of the Air Force bundled occupational fall prevention efforts
Socias-Morales C , Gwilliam M , Gomes H , Stallings H , Burnham B , Chaumont Menéndez CK , Collins J . Am J Ind Med 2024 INTRODUCTION: Fall injuries are the second leading cause of traumatic injury and death for all US workers and are a leading injury concern for the Department of the Air Force (DAF). Bundled interventions can improve the likelihood of injury reduction, especially in large, heterogeneous working populations. In 2013, the DAF implemented the "Air Force Fall Prevention Focus," a bundled intervention of prevention efforts designed to reduce occupational fall injury events among DAF members. The purpose of this study is to describe the burden and risk factors associated with fall injuries and evaluate the effectiveness of the Fall Prevention Focus in reducing the burden of fall injuries. METHODS: The National Institute for Occupational Safety and Health (NIOSH) partnered with the US Air Force Safety Center (AFSEC) to examine the impact of the Fall Prevention Focus as a bundled intervention. Injury events included a narrative description of the injury event, demographics, work environment, job tasks, and other structured details. Descriptive statistics and pre-post longitudinal modeling were used to evaluate changes in fall injury rates. RESULTS: The Fall Prevention Focus Implementation (2013-2018) resulted in an annual 10.4% (95% confidence interval [CI]: 8.5%, 12.2%) reduction, and a 6-year cumulative 48.3% (95% CI: 41.4%, 54.3%) reduction in fall injury event rates by 2018. DISCUSSION: Safety in the DAF involves a comprehensive approach. Documenting the impact of the Fall Prevention Focus may help translate these findings to improve fall prevention efforts in other sectors of the military and high fall-risk industries in the private sector, such as construction. |
| Circular RNA hsa_circ_0008726 targets the hsa-miR-206-3p/KLF4 axis to modulate 4,4'-methylene diphenyl diisocyanate-glutathione conjugate-induced chemokine transcription in macrophages
Lin CC , Law BF , Hettick JM . Cells 2025 13 (20) 1725 Exposure to 4,4'-methylene diphenyl diisocyanate (MDI) in the workplace may lead to the development of occupational asthma (OA). However, the specific mechanism(s) by which MDI induces OA are poorly understood. Previous reports have demonstrated that MDI and MDI-glutathione (GSH) conjugate exposure downregulates endogenous human/murine (hsa/mmu)-microRNA(miR)-206-3p, resulting in the activation of mmu/hsa-miR-206-3p-regulated signaling pathways in macrophages. Circular RNAs (circRNAs) regulate many important biological processes by targeting endogenous miRs; however, whether MDI/MDI-GSH exposure may influence circRNA expressions is unknown. Several circRNAs have been identified that regulate hsa-miR-206-3p. We hypothesize that MDI-GSH conjugate exposure induces endogenous circRNA(s) to regulate hsa-miR-206-3p in macrophages. The expression of candidate hsa-miR-206-3p-binding circRNAs was determined from MDI-GSH conjugate-treated differentiated THP-1 macrophages using RT-qPCR. MDI-GSH exposures induced hsa_circ_0008726 and its host gene transcript DNAJB6, whereas other circRNA(s) examined were either not detected or unchanged. RNA-induced silencing complex-immunoprecipitation (RISC-IP) experiments confirm that hsa-miR-206-3p can bind to hsa_circ_0008726. The expressions of endogenous hsa-miR-206-3p, hsa-miR-206-3p-regulated KLF4, and KLF4-activated M2 macrophage-associated markers and chemokines were up-/down-regulated by transfection of hsa_circ_0008726 siRNAs or hsa_circ_0008726 overexpression plasmid in macrophages, respectively. These results suggest MDI-GSH exposure downregulates hsa-miR-206-3p via induction of endogenous hsa_circ_0008726/DNAJB6, resulting in the upregulation of hsa-miR-206-3p-mediated regulations in macrophages. |
| Analysis of mpox by occupation and industry in seven U.S. jurisdictions, May 2022-March 2023

Int J Environ Res Public Health 2025 21 (10) 1317 During responses to outbreaks, the collection and analysis of data on employed case patients' industry and occupation are necessary to better understand the relationship between work and health outcomes. The occurrence of mpox by occupation and industry has not previously been assessed in the context of the 2022 outbreak. We analyzed employment data from 2548 mpox cases reported to the U.S. Centers for Disease Control and Prevention from surveillance systems in seven U.S. jurisdictions and population-based reference data on employment patterns from the U.S. Bureau of Labor Statistics to describe the differential proportionate distribution of cases across occupation and industry groups using the proportionate morbidity ratio. In gender-specific analyses, we found that men employed in certain occupations and industries had a higher relative risk of mpox than others. While occupational transmission cannot be ruled out, it is more likely that individuals with personal and behavioral risk factors for mpox were more likely to work in these occupations and industries. This analysis provides an example of collecting and analyzing occupation and industry data in case reports to understand possible differences in risk by occupation and industry in infectious disease outbreak investigation and help inform resource allocation, messaging, and response. |
| A qualitative assessment of changes in occupational exposures among healthcare facility workers
Gimeno Ruiz de Porras D , Patel J , Conway S , Pompeii L , Mitchell LE , Carson A , Whitehead LW , Han I , Zock JP , Henneberger PK , Patel R , De Los Reyes J , Delclos GL . Workplace Health Saf 2024 21650799241284085 Adult-onset asthma, notably prevalent among healthcare professionals, especially nurses, is often attributed to occupational factors such as exposure to cleaning agents. Studies consistently underscore the substantial role of such exposure in work-related asthma among hospital staff. We aimed to (a) identify and characterize current practices in cleaning and aerosolized medication administration; (b) assess changes in practices since a similar 2003 study of Texas healthcare workers; and (c) identify factors contributing to diverse exposures within healthcare job categories. We conducted focus groups with 38 participants in 6 healthcare settings, analyzing current practices, changes since 2003, and factors contributing to exposure diversity. We used a three-step approach for data analysis, including sociodemographic characterization, a scissor-and-sort technique for exposure description, and qualitative content analysis. Participants were primarily healthcare providers (76%) and housekeepers/cleaners (11%) who reported exposure to aerosolized medications, cleaning products, adhesives, and solvents. Participants reported transitioning from cleaning practices to new formulas with reduced odors and shifting from spray cleansers to wipes. Personal protective equipment (PPE) used during cleaning tasks varied, with training differing among job categories. Aerosolized medication administration varied among facilities, with reported medication types and protocol changes over time. The results emphasized the significance of maintaining uniform protection, disseminating knowledge, and consistently adhering to PPE protocols in the healthcare environment. Addressing the identified gaps in comprehension and potential sources of exposure variability requires additional focus on occupational health and safety initiatives. |
| An observational analysis of the impact of deltamethrin + piperonyl butoxide insecticide-treated nets on malaria case incidence and entomological indicators in Ebonyi State, Nigeria, 2017-2021
Davis KM , Okoko OO , Oduola AO , Inyama PU , Uneke CJ , Ambrose K , Seyoum A , Uhomoibhi P , Rhoda DA , Clary CB , Millar J , Littrell M , Rogers JH , Yoshimizu M , Inyang U , Maire M , Burnett SM . Malar J 2024 23 (1) 317 BACKGROUND: Intense pyrethroid resistance threatens the effectiveness of the primary vector control intervention, insecticide-treated nets (ITNs), in Nigeria, the country with the largest malaria burden globally. In this study, the epidemiological and entomological impact of a new type of ITN (piperonyl-butoxide [PBO] ITNs) distributed in Ebonyi State were evaluated. The epidemiological impact was also compared to the impact of standard pyrethroid-only ITNs in Cross River State. METHODS: A controlled interrupted time series analysis was conducted on monthly malaria incidence data collected at the health facility level, using a multilevel mixed-effects negative binomial model. Data were analysed two years before and after the PBO ITN campaign in Ebonyi State (December 2017 to November 2021). A pre-post analysis, with no comparison group, was used to assess the impact of PBO ITNs on human biting rates and indoor resting density in Ebonyi during the high transmission season immediately before and after the PBO ITN campaign. RESULTS: In Ebonyi, PBO ITNs were associated with a 46.7% decrease (95%CI: -51.5, -40.8%; p < 0.001) in malaria case incidence in the 2 years after the PBO ITN distribution compared to a modelled scenario of no ITNs distributed, with a significant decrease from 269.6 predicted cases per 1000 population to 143.6. In Cross River, there was a significant 28.6% increase (95%CI: -10.4, 49.1%; p < 0.001) in malaria case incidence following the standard ITN distribution, with an increase from 71.2 predicted cases per 1000 population to 91.6. In Ebonyi, the human biting rate was 72% lower (IRR: 0.28; 95%CI 0.21, 0.39; p < 0.001) and indoor resting density was 73% lower (IRR: 0.27; 95%CI 0.21, 0.35; p < 0.001) after the PBO ITNs were distributed. CONCLUSIONS: The epidemiological and entomological impact of the PBO ITNs underscore the impact of these ITNs in areas with confirmed pyrethroid resistance. These findings contribute to ongoing research on the impact of new types of ITNs in Nigeria, providing critical evidence for the Nigeria National Malaria Elimination Programme and other countries for future ITN procurement decisions as part of mass ITN campaign planning and malaria programming. |

| Proposed framework for adopting privacy-preserving record linkage for public health action
Pathak A , Serrer L , Bhalla M , King R , Mirel LB , Srinivasan A , Baier P , Zapata D , David-Ferdon C , Luxenberg S , Gundlapalli AV . J Public Health Manag Pract 2024 OBJECTIVES: To propose a framework for adoption of privacy-preserving record linkage (PPRL) for public health applications. METHODS: Twelve interviews with subject matter experts (SMEs) were conducted virtually and coded using an inductive approach. A collaborative session was conducted with SMEs to identify key steps in the PPRL project lifecycle which informed development of a PPRL implementation checklist. RESULTS: This framework has 2 decision-making levels: the organization level and the project or program level. Organization-level considerations include PPRL governance, the optimal choice among approved PPRL solutions, the need for longitudinal linkages, the potential issue of vendor lock-in, and costs. Program-level considerations include characteristics of the PPRL use case, linkage quality and accuracy, data privacy and use, security thresholds, compatibility with data owners' data architecture, and trade-offs between open-source and commercial PPRL solutions. A PPRL implementation checklist was developed to guide public health practitioners considering PPRL for data linkage. CONCLUSIONS: The framework may be considered by public health entities to guide adoption and implementation of PPRL in public health research and surveillance. Public health experts may refer to this framework and the PPRL implementation checklist when determining the appropriateness of PPRL for specific use cases and implementation planning. |
| State-level trends in access to Medicaid family planning services, 2008-2023
Williams AM , Saldarriaga EM , Cramer R . Health Serv Res 2024 OBJECTIVE: To characterize the landscape of policies that determine eligibility for family planning services through Medicaid programs and describe trends in eligibility and its determinants over time. DATA SOURCES AND STUDY SETTING: Secondary data were collected for all states in the United States for the years 2008 through 2023. Data on economic and demographic characteristics came from the American Community Survey (ACS). STUDY DESIGN: Our descriptive study characterized state adoptions of Medicaid family planning section 1115 waivers and state plan amendments (SPA) and their eligibility criteria. We then estimated the proportion of women aged 19-44 years who were eligible for family planning services through Medicaid and identified the key determinants of changes in eligibility, by state and year. DATA COLLECTION/EXTRACTION METHODS: Information on state Medicaid policies was extracted from documentation on the Centers for Medicare & Medicaid Services website. When estimating the eligible population sizes, the denominator was women aged 19-44 years, the group most likely to be eligible for Medicaid family planning programs. Supplemental data on program enrollment or utilization were collected from states' websites and reports. PRINCIPAL FINDINGS: Though eligibility limits for family planning through Medicaid generally increased over time, the proportion of women aged 19-44 years eligible for at least limited benefits decreased from 45.0% in 2012 to 39.4% in 2022, largely because of increases in household income. Trends varied considerably across states and by eligibility pathway. Among women with incomes below the poverty level, the proportion who were not eligible for Medicaid family planning services decreased from 6.3% in 2013 to 1.5% in 2022. CONCLUSIONS: Our data demonstrated substantial geographic and temporal variation in eligibility for family planning services through Medicaid. We identified key drivers of eligibility changes that may have important implications for health services analyses of means-tested public programs. |
| Substance use and help seeking as coping behaviors among parents and unpaid caregivers of adults in the United States during the COVID-19 pandemic
Varma P , DePadilla L , Czeisler MÉ , Rohan EA , Weaver MD , Quan SF , Robbins R , Patel CG , Melillo S , Drane A , Winnay SS , Lane RI , Czeisler CA , Howard ME , Rajaratnam SMW , Matjasko JL . Am J Drug Alcohol Abuse 2024 1-13 Background: During the COVID-19 pandemic, caregiving responsibilities may have been associated with increased substance use.Objectives: To characterize substance use to cope with stress and willingness to seek help among (i) parents, (ii) unpaid caregivers of adults, and (iii) parent-caregivers.Methods: Data were analyzed for 10,444 non-probabilistic internet-based survey respondents of the COVID-19 Outbreak Public Evaluation (COPE) initiative (5227 females, 5217 males). Questions included new or increased substance use, substance use in the past 30 days to cope, insomnia, mental health, and willingness to seek help.Results: Nearly 20% of parents and unpaid caregivers of adults each reported new or increased use of substances to cope with stress or emotions; 65.4% of parent-caregivers endorsed this response. Compared to non-caregivers, all caregiver groups had higher odds of new or increased use of substances, with parent-caregivers showing the largest effect size (aOR: 7.19 (5.87-8.83), p < .001). Parent-caregivers had four times the adjusted odds of using drugs other than cannabis (aOR: 4.01 (3.15-5.09), p < .001) compared to non-caregivers.Conclusions: Caregivers may initiate or increase substance use as a coping strategy when under stress. The higher odds of substance use underscores the importance of efforts to screen for sleep disturbances and adverse mental health symptoms, particularly among parent-caregivers. Clinicians may consider asking patients about family situations more broadly to help identify people who may be experiencing stress related to caregiving and, if indicated, offer treatment to potentially alleviate some of the risks. |

Am J Health Promot 2024 8901171241293419 OBJECTIVE: Identify commercial tobacco cessation interventions for American Indian and Alaska Native (AI/AN) communities, focusing on strategies used to advance health equity, including strategies to address social determinants of health (SDOH), community engagement, and cultural tailoring. DATA SOURCE: We searched Medline, Embase, PsycINFO, Cochrane Library, CINAHL, Scopus, ProQuest Central, Academic Search Complete, JSTOR, and Indigenous/Tribal health-related journals and databases. STUDY INCLUSION AND EXCLUSION CRITERIA: We included peer-reviewed studies on commercial tobacco cessation for AI/AN persons published January 1998-April 2023 that reported quit rates/attempts. We excluded studies that only used pharmaceutical interventions. DATA EXTRACTION: Two reviewers independently assessed each study against our inclusion/exclusion criteria. A reviewer extracted data, and another checked for completeness. DATA SYNTHESIS: Synthesis focused on reported intervention effectiveness and strategies used for addressing SDOH, community engagement, and cultural tailoring. We used a synthesis matrix which allowed for comparison across studies. RESULTS: We screened 1116 articles and included 12 for synthesis. Of the 12, five engaged community health workers; four included SDOH elements; and six were reported effective. Of these six, five included early-stage community engagement and four were culturally tailored. CONCLUSIONS: There are few commercial tobacco cessation interventions for AI/AN populations. Building capacity, including tribal capacity, to develop and test multi-level, culturally grounded cessation interventions that address relevant SDOH may advance commercial tobacco cessation efforts in these populations. |

| Prevalence of cannabis use among US workers in 15 states, 2016-2020
Evoy R , Victoroff T . Am J Public Health 2024 114 S645-s653 Objectives. To examine the prevalence of cannabis use among US workers using data from the US Behavioral Risk Factor Surveillance System (BRFSS) during 2016 to 2020. Methods. We analyzed past 30-day cannabis use among US workers. We calculated weighted prevalence and adjusted prevalence ratios (APRs) of cannabis use for working adults by industry groups, occupation groups, and sociodemographic characteristics (e.g., sex, education, age, race/ethnicity). Results. During the 5-year survey period, the weighted prevalence of past 30-day cannabis use among adult US workers from the 15 states included in the BRFSS was 10.7%. The industry group with the highest weighted prevalence of use was accommodation and food services (20.7%), and the highest-ranking occupation group was food preparation and service (21.9%). The industry group with the highest APR was accommodation and food services (APR = 1.31; 95% confidence interval [CI] = 1.10, 1.55), and the occupation group with the highest APR was arts, design, entertainment, sports, and media (APR = 1.91; 95% CI = 1.52, 2.41). Conclusions. Cannabis use among US workers varied widely by sex, age, race, education, industry groups, and occupation groups. A more accurate understanding of this variation can help guide research, focus policy discussions, and prioritize health messaging.

| Tobacco product use among middle and high school students - National Youth Tobacco Survey, United States, 2024
Jamal A , Park-Lee E , Birdsey J , West A , Cornelius M , Cooper MR , Cowan H , Wang J , Sawdey MD , Cullen KA , Navon L . MMWR Morb Mortal Wkly Rep 2024 73 (41) 917-924 Use of tobacco products in any form is unsafe, and nearly all tobacco product use begins during adolescence. CDC and the Food and Drug Administration (FDA) analyzed data from the 2024 National Youth Tobacco Survey to determine tobacco product use among U.S. middle school (grades 6-8) and high school (grades 9-12) students. In 2024, current (previous 30-day) use of any tobacco product was reported by 10.1% of high school students (representing 1.58 million students) and 5.4% of middle school students (representing 640,000 students). Among all students, e-cigarettes were the most commonly reported tobacco product currently used (5.9%), followed by nicotine pouches (1.8%), cigarettes (1.4%), cigars (1.2%), smokeless tobacco (1.2%), other oral nicotine products (1.2%), heated tobacco products (0.8%), hookahs (0.7%), and pipe tobacco (0.5%). During 2023-2024, among all students, the estimated number who reported current use of any tobacco product decreased from 2.80 to 2.25 million students; e-cigarette use decreased (from 2.13 to 1.63 million students); and hookah use decreased (from 290,000 to 190,000 students). Among high school students, current use of any tobacco product decreased from 12.6% to 10.1% of students, and e-cigarette use decreased from 10.0% to 7.8%. Among middle school students, no statistically significant changes occurred. Evidence-based strategies can help prevent initiation and promote cessation of tobacco product use among U.S. youths. |
| A quantitative and systematic analysis of Anopheles stephensi bionomics and control approaches
Mwema T , Zohdy S , Sundaram M , Lepczyk CA , Narine L , Willoughby JR . Acta Trop 2024 260 107431 Anopheles stephensi is a mosquito endemic to South Asia and the Arabian Peninsula that has recently been detected in eight African countries, posing a significant threat to global malaria control efforts. A challenge with An. stephensi is that it requires unique surveillance and control tools when compared to other malaria vectors. Through a systematic literature review, we investigated the efficacy of trapping methods and controls for An. stephensi mosquitoes, with a focus on studies of its behavior and biology. Data from 83 articles (native range: Afghanistan, India, Iran, Iraq, Pakistan, and Qatar; invasive range: Djibouti, Ethiopia, Sri Lanka, Saudi Arabia, and Sudan) met our study inclusion criteria. Data from these studies revealed that using host-seeking animal baited traps increased the number of mosquitoes collected per trap per day in the native range when compared to host-seeking human baited traps. However, these differences were not present in data collection rate assessments from the invasive range. We also found that An. stephensi equally used a large variety of breeding habitats in the native range, but that it tended to prefer water reservoirs and wastewater in the invasive range. Finally, we found that temephos, fenthion, Bacillus thuringiensis israelensis, and Beauveri bassiana were more effective at reducing larvae in their native range compared to the approaches found in our systematic literature search, but the relative effectiveness of these approaches in the invasive range was less clear. Understanding proven historical surveillance and control approaches is essential to the advancement of invasive An. stephensi mitigation efforts, but continued investigations in the invasive range are critical to reducing the impacts of malaria morbidity and mortality. |
| Reemergence of Oropouche virus in the Americas and risk for spread in the United States and its territories, 2024
Guagliardo SAJ , Connelly CR , Lyons S , Martin SW , Sutter R , Hughes HR , Brault AC , Lambert AJ , Gould CV , Staples JE . Emerg Infect Dis 2024 30 (11) 2241-2249 Oropouche virus has recently caused outbreaks in South America and the Caribbean, expanding into areas to which the virus was previously not endemic. This geographic range expansion, in conjunction with the identification of vertical transmission and reports of deaths, has raised concerns about the broader threat this virus represents to the Americas. We review information on Oropouche virus, factors influencing its spread, transmission risk in the United States, and current status of public health response tools. On the basis of available data, the risk for sustained local transmission in the continental United States is considered low because of differences in vector ecology and in human-vector interactions when compared with Oropouche virus-endemic areas. However, more information is needed about the drivers for the current outbreak to clarify the risk for further expansion of this virus. Timely detection and control of this emerging pathogen should be prioritized to mitigate disease burden and stop its spread. |
| Rickettsia rickettsii subsp. californica subsp. nov., the etiologic agent of Pacific Coast tick fever
Paddock CD , Karpathy SE , Henry A , Ryle L , Hecht JA , Hacker JK , Padgett KA , Kjemtrup AM , Bullock H , Lane RS , Ladner JT . J Infect Dis 2024
The etiologic agent of Pacific Coast tick fever (PCTF), a moderately severe tickborne illness that resembles Rocky Mountain spotted fever (RMSF), was first isolated in 1966 from specimens of Dermacentor occidentalis (the Pacific Coast tick) obtained in California. For several decades, this bacterium was identified ambiguously as the unclassified spotted fever group Rickettsia species 364-D, Rickettsia 364, or Rickettsia philipii. However, none of these epithets satisfied criteria of formal bacterial nomenclature. Data developed from mouse serotyping studies performed 45 years ago, and multi-locus sequence typing several decades later, indicated that this bacterium was similar to, but distinct from isolates of Rickettsia rickettsii, the etiological agent of RMSF. We applied an integrative taxonomic approach, combining phenotypic, ecological, and clinical data with whole genome sequencing of 11 contemporary isolates of this pathogen to identify it as a distinct subspecies of R. rickettsii, and propose the name Rickettsia rickettsii subsp. californica subsp. nov. |

On September 28, 2023, a kitten aged approximately 6 weeks found in Omaha, Nebraska, had test results positive for rabies at the Nebraska Veterinary Diagnostic Center (NVDC) after dying with neurologic signs and having bitten and scratched its caretakers. Preliminary investigation identified 10 exposed persons for whom postexposure prophylaxis (PEP)(†) was recommended. Subsequent variant-typing by NVDC yielded a presumptive positive result for the Eastern raccoon rabies virus variant (RRVV), which CDC confirmed on October 6. |
