The Centers for Disease Control and Prevention (CDC) funds tuberculosis (TB) Centers of Excellence (COEs) that support TB control and prevention efforts in the United States. In 2018, the TB COEs conducted a multiphased assessment among U.S. staff involved in TB service delivery to identify needs related to TB training, resources, and medical consultation. Representatives from each TB COE and CDC's Division of TB Elimination formed a workgroup to guide the design of the needs assessment. The group used an online survey for data collection. Participants were staff working in some capacity on TB within the United States, Puerto Rico, and the U.S. Virgin Islands. Staff could be in non-public health (e.g., community health center, hospital, laboratory, private practice) or public health (state or local health department staff responsible for TB) settings and did not have to be a clinical health care provider (N = 1,482). We identified four priority areas for future TB training and education efforts. These areas include (1) focus on key topics; (2) tailor training and products to different professions, settings, and skill levels; (3) keep learners updated on the latest resources and best practices; and (4) use a mix of training methods and formats. The findings highlighted future priorities for TB training and education and were shared with health department TB programs throughout the United States.

INTRODUCTION: There is limited information about vaccine-preventable disease (VPD) surveillance cost. To address this gap, retrospective micro-costing studies of pre-COVID-19 pandemic VPD surveillance were conducted in Nepal and Ethiopia. Based on these evaluations-the sole cost evaluations on comprehensive VPD surveillance-this article provides methodological considerations and recommendations for other countries planning to conduct VPD surveillance costing studies to inform planning and budgeting. METHODS: The methods used for each study were systematically compared by key themes: costing perspective, cost categories, costing approach, allocation of shared costs, sampling criteria, extrapolation strategies, data collection, and analytic adjustments. For each theme, investigators identified methodologic challenges and potential strategies to address them, compared study methodologies to surveillance costing guidelines, and recommended practices for future such studies. RESULTS: The studies used similar perspectives and VPD inclusion criteria. Costs in Nepal were collected and analyzed by a subset of surveillance core and support functions, whereas the Ethiopia study categorized costs using surveillance support functions from the Global Strategy on Comprehensive VPD Surveillance. A mix of random and purposive sampling of surveillance sites was used in both studies. Surveillance sites were selected considering the strata of interest at each administrative level. Results from both studies were extrapolated country-wide using sampling weights and assumptions about the representativeness of purposively sampled units. DISCUSSION: The review highlighted potential methodologic tradeoffs in utility and precision of results based on the lessons learned from two country VPD surveillance cost studies. The advantages of collecting and using cost estimates by VPD surveillance core versus support function for program budgeting for varied audiences should be explored in future studies. Sampling strategies should be developed with consideration for the precision needed for the intended use of costing results. The resulting recommendations can improve and standardize the conduct and interpretation of future such studies.

The rising star hypothesis proposes that characteristics of “rising star” protégés already set them up for success, such that mentoring is a byproduct of their ambition. Alternatively, the influential mentor hypothesis states that protégés experience success due to the positive influence of mentoring. Herein, we test whether rising star characteristics (need for achievement and career initiative behaviors) precede or follow informal mentorship. Using data from a sample of 94 protégés (recruited from a hospital) over two time points (six-week lag), we found best evidence for a mix of the rising star and influential mentor hypotheses, in which career initiative behaviors predict the number of informal mentors, and in turn, need for achievement. Cross-lagged effects were probed and provide evidence that the benefits of informal mentoring does not seem to extend to formal mentoring. Practical implications are highlighted, including the benefits of multiple mentors and alternatives to traditional mentoring. © The Author(s) 2025.

In addition to oropharyngeal cancers, evidence suggests there may be an etiologic role for human papillomavirus (HPV) in some other head and neck cancers arising from the oral cavity and larynx. We estimated the burden of HPV16-attributable cancers of the oral cavity (ICD-O-3 site codes C02.0-C02.3, C02.9, C03.0, C03.1, C03.9, C04.0, C04.1, C04.8, C04.9, C05.0, C05.8, C05.9, C06.0-C06.2, C06.8, C06.9) and larynx (C32.0-C32.3, C32.8, C32.9) in the United States by pooling estimates from published case studies to calculate HPV16-attributable fractions (HPV16-AFs) and applying the HPV16-AFs to 2016-2020 US Cancer Statistics data. During 2016-2020, of an average annual number of 12,612 oral cavity cancers, 3.9% (n = 497) were estimated to be attributable to HPV16. Of an average annual number of 11,170 laryngeal cancers, 2.8% (n = 309) were estimated to be attributable to HPV16. This information can improve surveillance of HPV16-attributable cancers in the US population and inform our understanding of the potential impact of HPV vaccination on cancers at these two sites.

PURPOSE: Renal ultrasounds are performed in patients with myelomeningocele to screen for markers of kidney health, including hydronephrosis. We evaluated the diagnostic accuracy of hydronephrosis to screen for low kidney function defined by estimated glomerular filtration rate (eGFR). MATERIALS AND METHODS: We performed a retrospective cross-sectional study using data from 2 cohorts of children and youth with myelomeningocele. The first cohort is the Urological Management to Preserve Initial Renal Function Protocol for Young Children With Spina Bifida (UMPIRE; 2016-2022) and the second from the National Spina Bifida Patient Registry (NSBPR; 2009-2021). We identified patients aged 1 to 18 years with available eGFR data within 6 months of an ultrasound. We excluded NSBPR patients younger than 6 years to address potential duplication across cohorts. The primary outcome was eGFR < 90 mL/min/1.73 m(2), calculated using the bedside Schwartz formula. Hydronephrosis was dichotomized into any/none. We calculated sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of any hydronephrosis using eGFR as the reference standard. RESULTS: In UMPIRE, 221 patients were included with median age 2.4 years (IQR, 1.9-3.8) and 24% having eGFR < 90. Any hydronephrosis vs none conferred a sensitivity/specificity/PPV/NPV of 25%/75%/24%/77%, respectively. In NSBPR, 2269 patients were included with median age 13 years (IQR, 9.6-16.3) and 17% having eGFR < 90. Any hydronephrosis vs none conferred a sensitivity/specificity/PPV/NPV of 24%/87%/26%/85%, respectively. CONCLUSIONS: In 2 cohorts of children and youth with myelomeningocele, hydronephrosis conferred a sensitivity of ∼25% for a creatinine-based eGFR < 90 mL/min/1.73 m(2). This low sensitivity suggests that hydronephrosis alone is a poor screening marker of kidney health.

A significant portion of the work of developing and validating methods for volatile organic compound (VOC) sampling in workplace atmospheres involves the use of laboratory-generated atmospheres. The sample variability was evaluated from the dynamic atmosphere generation system used for VOC atmosphere generation and sampling. Characterization of the bias and variability of samples was done for a variety of atmospheres containing neat n-heptane and mixtures of VOCs sampled on activated coconut shell charcoal. Estimates of sampling variability ranged from 2% for neat n-heptane to 12% for a component in the 10 VOC mix. Sample variability increased for lower concentration samples and for mixtures of VOCs compared to single component atmospheres. This study can serve as a baseline for future atmosphere sampling experiments evaluating performance at lower concentrations and mixed VOC environments.

Rabies is a fatal encephalitic disease affecting all mammals. This report describes identification of raccoon rabies virus variant isolated from a stray kitten in an urban Midwestern city that is nonendemic for this virus variant. The kitten originally presented with nonspecific neurologic abnormalities. Astute veterinary, wildlife, and public health professionals played a critical role in the identification of this fatal zoonotic disease and the extensive public health and wildlife management response that ensued. This case serves as an important reminder of the risk of rabies in unvaccinated animals or those without known vaccination status, including stray animals.

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.

BACKGROUND: Although current guidelines recommend implantable cardioverter-defibrillator (ICD) placement in survivors of out-of-hospital cardiac arrest, contemporary data on secondary-prevention ICDs in survivors of out-of-hospital cardiac arrest remain limited. METHODS AND RESULTS: Using 2013 to 2019 CARES (Cardiac Arrest Registry to Enhance Survival) linked to Medicare, we identified 3226 patients aged ≥65 years with an initial shockable rhythm who survived to discharge without severe neurological disability. Multivariable hierarchical regression models were used to examine the association between patient variables and ICD placement and quantify hospital variation in ICD implantation. The mean age was 72.2 years, 23.5% were women, 10% were Black individuals, and 4% were Hispanic individuals. Overall, 997 (30.9%) patients received an ICD before discharge, 1266 (39.2%) at 90 days, and 1287 (39.9%) within 6 months. Older age (≥85 years), female sex, history of diabetes, calendar year, and presentation with acute myocardial infarction were associated with lower odds of ICD implantation, but race or ethnicity was not associated with ICD implantation. Among 297 hospitals, the median proportion of survivors receiving ICD at discharge was 28.6% (interquartile range, 20%-50%). The relative odds of ICD implantation varied by 62% across hospitals (median odds ratio, 1.62 [95% CI, 1.38-1.82]) after adjusting for case mix. CONCLUSIONS: Fewer than 1 in 3 survivors of out-of-hospital cardiac arrest due to a shockable rhythm received a secondary-prevention ICD before discharge. Although patient variables were associated with ICD implantation, there was no difference by race or ethnicity. Even after adjusting for patient case mix, ICD implantation varied markedly across hospitals.

ABSTRACTNipah virus (NiV) is an emerging zoonotic RNA virus that can cause fatal respiratory and neurological disease in animals and humans. Accurate NiV diagnostics and surveillance tools are crucial for the identification of acute and resolved infections and to improve our understanding of NiV transmission and circulation. Here, we have developed and validated a split NanoLuc luciferase NiV glycoprotein (G) biosensor for detecting antibodies in clinical and animal samples. This assay is performed by simply mixing reagents and measuring luminescence, which depends on the complementation of the split NanoLuc luciferase G biosensor following its binding to antibodies. This anti-NiV-G "mix-and-read" assay was validated using the WHO's first international standard for anti-NiV antibodies and more than 700 serum samples from the NiV-endemic country of Bangladesh. Anti-NiV antibodies from survivors persisted for at least 8 years according to both ⍺NiV-G mix-and-read and NiV neutralization assays. The ⍺NiV-G mix-and-read assay sensitivity (98.6%) and specificity (100%) were comparable to anti-NiV IgG ELISA performance but failed to detect anti-NiV antibodies in samples collected less than a week following the appearance of symptoms. Overall, the anti-NiV-G biosensor represents a simple, fast, and reliable tool that could support the expansion of NiV surveillance and retrospective outbreak investigations.

OBJECTIVE: To examine population-level scrotal cancer incidence rates and trends among adult men in the United States. METHODS: Data from the United States Cancer Statistics, covering approximately 96% of the United States population, were analyzed to calculate age-standardized incidence rates of scrotal cancer among men aged 18 years and older from 1999 to 2020. Trends in incidence rates were evaluated by age, race and ethnicity, Census region, and histology using joinpoint regression. RESULTS: Overall, 4669 men were diagnosed with scrotal cancer (0.20 per 100,000). Incidence rates were highest among men aged 70 years and older (0.82 per 100,000). Rates were higher among non-Hispanic Asian or Pacific Islander men (0.31 per 100,000) compared to other race and ethnicity groups. The most common histologic subtypes were squamous cell carcinoma (35.9%), extramammary Paget disease (20.8%), and sarcoma (20.5%). Incidence rates decreased by 2.9% per year from 1999 to 2019 for non-Hispanic Asian or Pacific Islander men, decreased by 8.1% per year from 1999 to 2006 for basal cell carcinomas, and increased by 1.8% per year from 1999 to 2019 for extramammary Paget disease; otherwise, rates remained stable for all other variables examined. CONCLUSION: While scrotal cancer incidence rates were higher than previously reported, rates were still low and stable over time.

BACKGROUND: Bacterial etiologies of acute otitis media (AOM) have shifted from the introduction of pneumococcal conjugate vaccines (PCVs), antibiotic selection and competition among species. We characterized Streptococcus pneumoniae (Spn), Haemophilus influenzae (Hflu) and Moraxella catarrhalis (Mcat) in the nasopharynx during well-child healthy visits and at the onset of AOM, and in middle ear fluid (MEF) of children with AOM to assess anticipated effects of higher-valency PCVs (PCV15 and PCV20). METHODS: From September 2021 to September 2023, we conducted a prospective longitudinal cohort study of PCV13 immunized children 6-36 months old. MEF was collected via tympanocentesis. Serotyping and antibiotic susceptibility testing were performed on Spn, Hflu and Mcat isolates. RESULTS: We obtained 825 nasopharyngeal and 216 MEF samples from 301 children. The order of frequency of nasopharyngeal colonization was Mcat, Spn and Hflu; Hflu was the predominant otopathogen in MEF. Among Spn isolates, non-PCV15, non-PCV20 serotypes predominated in the nasopharynx and in MEF; the most frequent serotype was 35B. Among MEF samples, 30% of Spn isolates were amoxicillin nonsusceptible; 23% of Hflu isolates and 100% of Mcat isolates were β-lactamase-producing. CONCLUSION: The majority of Spn isolates among young children were non-PCV15, non-PCV20 serotypes, especially serotype 35B; therefore, the impact of higher-valency PCVs in reducing pneumococcal colonization or AOM is expected to be limited. Hflu continues to be the most frequent AOM pathogen. Antibiotic susceptibility data suggest a high dose of amoxicillin/clavulanate or alternative drugs that are effective against contemporary mix of otopathogens could be considered for optimal empiric selection to provide the best efficacy.

Hysterectomy protects against cervical cancer when the cervix is removed. However, measures of cervical cancer incidence often fail to exclude women with a hysterectomy from the population at risk denominator, underestimating and distorting disease burden. In this study, we estimated hysterectomy prevalence from the Behavioral Risk Factor Surveillance System surveys to remove the women who were not at risk of cervical cancer from the denominator and combined these estimates with the United States Cancer Statistics data. From these data, we calculated age-specific and age-standardized incidence rates for women aged >30 years from 2001-2019, adjusted for hysterectomy prevalence. We calculated the difference between unadjusted and adjusted incidence rates and examined trends by histology, age, race and ethnicity, and geographic region using Joinpoint regression. The hysterectomy-adjusted cervical cancer incidence rate from 2001-2019 was 16.7 per 100,000 women-34.6% higher than the unadjusted rate. After adjustment, incidence rates were higher by approximately 55% among Black women, 56% among those living in the East South Central division, and 90% among women aged 70-79 and >80 years. These findings underscore the importance of adjusting for hysterectomy prevalence to avoid underestimating cervical cancer incidence rates and masking disparities by age, race, and geographic region.

INTRODUCTION: Scrotal squamous cell carcinomas (SCCs) are rare malignancies that are not considered to be associated with the human papillomavirus (HPV) by the International Agency for Research on Cancer. However, recent studies have detected HPV in these cancers. We sought to determine the presence of HPV types among scrotal cancer cases identified through population-based cancer registries. METHODS: Primary scrotal SCCs diagnosed from 2014 to 2015 were identified, and tissue sections from formalin-fixed, paraffin-embedded tissue blocks were obtained for laboratory testing. A pathology review was performed to confirm morphology. HPV testing was performed using L1 consensus polymerase chain reaction analysis. Immunohistochemistry was used to evaluate p16INK4a (p16) expression. RESULTS: Five cases of scrotal SCC were identified from 1 cancer registry. Age at diagnosis ranged from 34 to 75 years (median, 56 years). Four cases were non-Hispanic White, and 1 was non-Hispanic Black. The morphologic subtype of 4 cases was keratinizing (usual), and 1 case was verrucous (warty) histologic subtype. Two of the usual cases of SCC were HPV-negative and p16-negative, and 2 were positive for HPV16 and p16. The verrucous (warty) SCC subtype case was HPV6-positive and p16-negative. CONCLUSIONS: The presence of HPV16 and p16 overexpression in the examined tissue specimens lends additional support for the role of HPV in the etiology of scrotal SCC.

We estimated the population-level incidence of human papillomavirus (HPV) positive oropharyngeal, cervical, and anal cancers by smoking status. We combined HPV DNA genotyping data from the Centers for Disease Control and Prevention's Cancer Registry Sentinel Surveillance System with data from the Kentucky Cancer Registry and Behavioral Risk Factor Surveillance System across smoking status. During 2004-2005 and 2014-2015 in Kentucky, most cases of oropharyngeal (63.3%), anal (59.7%), and cervical (54.9%) cancer cases were among persons who ever smoked. Population-level incidence rate was higher among persons who ever smoked than never smoked for HPV-positive oropharyngeal (7.8 vs 2.1; adjusted incidence rate ratio [RRadj] = 2.6), cervical (13.7 vs 6.8; RRadj = 2.0), and anal (3.9 vs 1.6; RRadj = 2.5) cancers. These findings indicate that smoking is associated with increased risk of HPV-positive oropharyngeal, cervical, and anal cancers, and the population-level burden of these cancers is higher among persons who ever smoked.

Streptococcus pneumoniae (pneumococcus) is a leading vaccine-preventable cause of childhood invasive disease. Nigeria has the second highest pneumococcal disease burden globally, with an estimated ~49 000 child deaths caused by pneumococcal infections each year. Ten-valent pneumococcal conjugate vaccine (GSK; PCV10) was introduced in December 2014 in a phased approach. However, few studies have characterized the disease-causing pneumococci from Nigeria. This study assessed the prevalence of serotypes, antibiotic susceptibility and genomic lineages using whole genome sequencing and identified lineages that could potentially escape PCV10 (GSK). We also investigated the potential differences in pneumococcal lineage features between children with and without sickle cell disease. A collection of 192 disease-causing pneumococcal isolates was obtained from Kano (n=189) and Abuja (n=3) states, Nigeria, between 1 January 2014 and 31 May 2018. The majority (99 %, 190/192) of specimens were recovered from children aged 5 years or under. Among them, 37 children had confirmed or traits of sickle cell disease. Our findings identified 25 serotypes expressed by 43 Global Pneumococcal Sequence Clusters (GPSCs) and 85 sequence types (STs). The most common serotypes were 14 (18 %, n=35), 6B (16 %, n=31), 1 (9 %, n=17), 5 (9 %, n=17) and 6A (9 %, n=17); all except serotype 6A are included in PCV10 (GSK). PCV10 (SII; PNEUMOSIL) and PCV13 formulations include serotypes 6A and 19A which would increase the overall coverage from 67 % by PCV10 (GSK) to 78 and 82 %, respectively. The pneumococcal lineages were a mix of globally spreading and unique local lineages. Following the use of PCV10 (GSK), GPSC5 expressing serotype 6A, GPSC10 (19A), GPSC26 (12F and 46) and GPSC627 (9L) are non-vaccine type lineages that could persist and potentially expand under vaccine-selective pressure. Approximately half (52 %, 99/192) of the pneumococcal isolates were resistant to the first-line antibiotic penicillin and 44 % (85/192) were multidrug-resistant. Erythromycin resistance was very low (2 %, 3/192). There was no significant difference in clinical manifestation, serotype prevalence or antibiotic resistance between children with and without traits of or confirmed sickle cell disease. In summary, our findings show that a high percentage of the pneumococcal disease were caused by the serotypes that are covered by currently available vaccines. Given the low prevalence of resistance, macrolide antibiotics, such as erythromycin, should be considered as an option to treat pneumococcal disease in Nigeria. However, appropriate use of macrolide antibiotics should be vigilantly monitored to prevent the potential increase in macrolide resistance.

SARS-CoV-2 emerged in late 2019 and has since spread around the world, causing a pandemic of the respiratory disease COVID-19. Detecting antibodies against the virus is an essential tool for tracking infections and developing vaccines. Such tests, primarily utilizing the enzyme-linked immunosorbent assay (ELISA) principle, can be either qualitative (reporting positive/negative results) or quantitative (reporting a value representing the quantity of specific antibodies). Quantitation is vital for determining stability or decline of antibody titers in convalescence, efficacy of different vaccination regimens, and detection of asymptomatic infections. Quantitation typically requires two-step ELISA testing, in which samples are first screened in a qualitative assay and positive samples are subsequently analyzed as a dilution series. To overcome the throughput limitations of this approach, we developed a simpler and faster system that is highly automatable and achieves quantitation in a single-dilution screening format with sensitivity and specificity comparable to those of ELISA.One sentence summary Protein complementation enables mix-and-read SARS-CoV-2 serology that rivals sensitivity and specificity of ELISA but excels in throughput and quantitation.Competing Interest StatementThe authors have declared no competing interest.Funding StatementThis research was funded by the Centers for Disease Control and Prevention.Author DeclarationsI confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.YesThe details of the IRB/oversight body that provided approval or exemption for the research described are given below:Residual specimen materials were used for diagnostics development under a protocol that was reviewed and approved by the CDC Institutional Review Board (See 45 C.F.R. part 46; 21 C.F.R. part 56)All necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived.YesI understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov.

BACKGROUND: There is little information comparing the performance of community acquired central nervous system infections (CNSI) treatment by intensive care units (ICUs) specialized in infectious diseases with treatment at other ICUs. Our objective was to reduce these gaps, creating bases for benchmarking and future case-mix classification. METHODS: This is a retrospective observational cohort of 785 admissions with 82 cases of CNSI admitted to the ICU of an important Brazilian referral center for infectious diseases (INI) between January 2012 and January 2019. Comparisons were made to data retrospectively collected from the 303,500 intensive care admissions from the Brazilian state health care system included in the Epimed Monitor database. Clinical, epidemiologic, and performance indicators: the standardized mortality rate (SMR) and the standardized resource use rate per ICU surviving patient (SRU) were collected. RESULTS: Case-mix infections profile and SMR/SRU data. SUS Mixed medical/surgical ICUs: SMR = 1.26, SRU = 1.59; SUS Neurological ICUs: SMR = 1.17, SRU = 2.23; INI ICU: SMR = 1.1, SRU = 1.1; INI ICU CNSI patients: SMR = 0.95, SRU = 1.01. CONCLUSIONS: Severe patients with CNSI can be efficiently and effectively treated in an ICU specialized in infectious diseases when compared to mixed medical/surgical and neurological ICUs from the public health system. At the same time, we provided profiling and a case-mix that can help and encourage benchmarking by other institutions and other countries.

OBJECTIVES: To identify the most important reasons underlying decisions to stock or not stock adult vaccines. STUDY DESIGN: US physicians, nurses, pharmacists, and administrators of internal medicine, family medicine, obstetrics/gynecology, and multispecialty practices who were involved in vaccine stocking decisions (N = 125) completed a best-worst scaling survey online between February and April 2018. METHODS: Sixteen potential factors influencing stocking decisions were developed based on key informant interviews and focus groups. Respondents selected factors that were most and least important in vaccine stocking decisions. Relative importance scores for the best-worst scaling factors were calculated. Survey respondents described which vaccines their practice stocks and reasons for not stocking specific vaccines. Subgroup analyses were performed based on the respondent's involvement in vaccine decision making, role in the organization, specialty, and affiliation status, as well as practice characteristics such as practice size, insurance mix, and patient age mix. RESULTS: Relative importance scores for stocking vaccines were highest for "cost of purchasing vaccine stock," "expense of maintaining vaccine inventory," and "lack of adequate reimbursement for vaccine acquisition and administration." Most respondents (97%) stocked influenza vaccines, but stocking rates of other vaccines varied from 39% (meningococcal B) to 83% (tetanus-diphtheria-pertussis). Best-worst scaling results were consistent across respondent subgroups, although the range of vaccine types stocked differed by practice type. CONCLUSIONS: Economic factors associated with the purchase and maintenance of vaccine inventory and inadequate reimbursement for vaccination services were the most important to decision makers when considering whether to stock or not stock vaccines for adults.

BACKGROUND AND AIMS: Rectal squamous cell carcinoma (SCC) is a rare malignancy, and the causal role of human papillomavirus (HPV) in these cancers is thought to be similar to anal cancer. We compared type-specific prevalence of HPV in rectal SCC to anal cancer. In rectal SCC, we evaluated the agreement between HPV prevalence and positivity for p16, a marker of oncogenic activity. METHODS: A stratified random sample of rectal SCCs and anal cancers diagnosed between 2014 and 2015 were identified from 3 statewide cancer registries in Iowa, Kentucky, and Louisiana. HPV testing was performed at the HPV laboratory at the Centers for Disease Control and Prevention. HPV types were described using hierarchical attribution to HPV16 and other oncogenic types, weighted for sampling design. In rectal SCC, we computed concordance and Cohen's kappa coefficient (κ) between HPV status and p16 positivity. RESULTS: A total of 39 rectal and 72 anal cancers were analyzed. HPV16 was the most common type in both rectal and anal cancer and did not differ significantly between sites (71.4% vs 82.1%; P = .32). Concordance between the presence of any HPV type and p16 positivity in rectal SCC was 92% with κ = 0.77. CONCLUSIONS: Rectal SCC and anal cancer have similar type-specific HPV prevalence, with HPV16 found most frequently. Substantial agreement between p16 and HPV status in rectal SCC lends additional support for the etiologic role of HPV in both anal and rectal cancer. Larger studies could be conducted to replicate these findings.

OBJECTIVES: The Centers for Disease Control and Prevention (CDC) recommends implementing Enhanced Barrier Precautions (EBP) for all nursing home (NH) residents known to be colonized with targeted multidrug-resistant organisms (MDROs), wounds, or medical devices. Differences in health care personnel (HCP) and resident interactions between units may affect risk of acquiring and transmitting MDROs, affecting EBP implementation. We studied HCP-resident interactions across a variety of NHs to characterize MDRO transmission opportunities. DESIGN: 2 cross-sectional visits. SETTING AND PARTICIPANTS: Four CDC Epicenter sites and CDC Emerging Infection Program sites in 7 states recruited NHs with a mix of unit care types (≥30 beds or ≥2 units). HCP were observed providing resident care. METHODS: Room-based observations and HCP interviews assessed HCP-resident interactions, care type provided, and equipment use. Observations and interviews were conducted for 7-8 hours in 3-6-month intervals per unit. Chart reviews collected deidentified resident demographics and MDRO risk factors (eg, indwelling devices, pressure injuries, and antibiotic use). RESULTS: We recruited 25 NHs (49 units) with no loss to follow-up, conducted 2540 room-based observations (total duration: 405 hours), and 924 HCP interviews. HCP averaged 2.5 interactions per resident per hour (long-term care units) to 3.4 per resident per hour (ventilator care units). Nurses provided care to more residents (n = 12) than certified nursing assistants (CNAs) and respiratory therapists (RTs) (CNA: 9.8 and RT: 9) but nurses performed significantly fewer task types per interaction compared to CNAs (incidence rate ratio (IRR): 0.61, P < .05). Short-stay (IRR: 0.89) and ventilator-capable (IRR: 0.94) units had less varied care compared with long-term care units (P < .05), although HCP visited residents in these units at similar rates. CONCLUSIONS AND IMPLICATIONS: Resident-HCP interaction rates are similar across NH unit types, differing primarily in types of care provided. Current and future interventions such as EBP, care bundling, or targeted infection prevention education should consider unit-specific HCP-resident interaction patterns.

BACKGROUND: Adolescents have poorer outcomes across the HIV cascade compared to adults. We aimed to assess progress in HIV case-finding, antiretroviral treatment (ART), viral load coverage (VLC), and viral load suppression (VLS) among adolescents enrolled in the U.S. President's Emergency Plan for AIDS Relief (PEPFAR)-supported programs over a three-year period that included the beginning of the COVID-19 pandemic. METHODS: We analyzed PEPFAR program data in 28 countries/regions for adolescents 10-19 years between year 1 (October 2017-September 2018), year 2 (October 2018-September 2019), and year 3 (October 2019-September 2020). We calculated the number and percent change for HIV tests, HIV-positive tests, and total number on ART. Calculated indicators included positivity, percent of positives newly initiated on ART (ART linkage), VLC (percent of ART patients on ART for ≥6 months with a documented viral load result within the past 12 months), and VLS (percent of viral load tests with <1000 copies/mL). RESULTS: Between Years 1 and 3, the number of HIV tests conducted decreased by 44.2%, with a 29.1% decrease in the number of positive tests. Positivity increased from 1.3% to 1.6%. The number of adolescents receiving ART increased by 10.4%. Additionally, ART linkage increased (77.8% to 86.7%) as did VLC (69.4% to 79.4%) and VLS (72.8% to 81.5%). CONCLUSIONS: Our findings demonstrate PEPFAR's success in increasing the adolescent treatment cohort. We identified ongoing gaps in adolescent case-finding, linkage, VLC, and VLS that could be addressed with a strategic mix of testing strategies, optimal ART regimens, and adolescent-focused service delivery models.

BACKGROUND: In 2019, South Africa, Nigeria, Tanzania, Democratic Republic of Congo, Uganda, Mozambique, Zambia, Angola, Cameroon, Zimbabwe, Ghana, Ethiopia, Malawi, Kenya, South Sudan and Côte d'Ivoire accounted for 80% of children living with HIV (CLHIV) not receiving HIV treatment. This manuscript describes pediatric HIV testing to inform case-finding strategies. METHODS: We analyzed US President's Emergency Plan for AIDS Relief monitoring, evaluation, and reporting data (October 1, 2018 to September 30, 2019) for these 16 countries. Number of HIV tests and positive results were reported by age band, country, treatment coverage and testing modality. The number needed to test (NNT) to identify 1 new CLHIV 1-14 years was measured by testing modality and country. The pediatric testing gap was estimated by multiplying the estimated number of CLHIV unaware of their status by NNT per country. RESULTS: Among children, 6,961,225 HIV tests were conducted, and 101,762 CLHIV were identified (NNT 68), meeting 17.6% of the pediatric testing need. Index testing accounted for 13.0% of HIV tests (29.7% of positive results, NNT 30), provider-initiated testing and counseling 65.9% of tests (43.6% of positives, NNT 103), and universal testing at sick entry points 5.3% of tests (6.5% of positives, NNT 58). CONCLUSIONS: As countries near HIV epidemic control for adults, the need to increase pediatric testing continues. Each testing modality - PITC, universal testing at sick entry points, and index testing - offers unique benefits. These results illustrate the comparative advantages of including a strategic mix of testing modalities in national programs to increase pediatric HIV case finding.

Vulvar cancer incidence has been rising in recent years, possibly due to increasing exposure to human papillomavirus (HPV). We assessed incidence rates of HPV-associated and non-HPV-associated vulvar cancers diagnosed from 2001 to 2017 in the United States (US). Using population-based cancer registry data covering 99% of the US population, incidence rates were calculated and stratified by age, race/ethnicity, stage, geographic region, and histology. The average annual percent change in incidence per year were calculated using joinpoint regression. From 2001 to 2017, the incidence of HPV-associated vulvar cancers increased by 1.2% per year, most notably among women who were aged 50-59 years (2.6%), 60-69 years (2.4%), and ≥ 70 years (0.9%); of White (1.5%) and Black (1.1%) race; diagnosed at an early (1.3%) and late (1.8%) stage; and living in the Midwest (1.9%), Northeast (1.4%), and South (1.2%). Incidence increased each year for HPV-associated histologic subtypes including keratinizing (4.7%), non-keratinizing (6.0%), and basaloid (3.1%) squamous cell carcinomas (SCCs), while decreases were found in warty (2.7%) and microinvasive (5.5%) SCCs. HPV-associated vulvar cancer incidence increased overall and among women aged over 50 years while remaining stable among women younger than 50 years. The overall incidence for non-HPV-associated cancers was stable. Continued surveillance of HPV-associated cancers will allow us to monitor future trends as HPV vaccination coverage increases in the US.

The World Health Organization recommends pre-exposure prophylaxis (PrEP) for individuals at substantial risk of HIV infection. The aim of this analysis is to quantify the individual risk of HIV infection over time, using a large database of high-risk individuals (n = 5583). We used data from placebo recipients in five phase III PrEP trials: iPrEx, conducted in men who have sex with men and transgender women; VOICE, conducted in young women at high sexual risk; Partners PrEP, conducted in HIV serodiscordant heterosexual couples; TDF2, conducted in high-risk heterosexual men and women; and BTS, conducted in persons who inject drugs. The probability of HIV infection over time was estimated using NONMEM7.4. We identified predictors of HIV risk and found a substantial difference in the risk of infection among and within trial populations, with each study including a mix of low, moderate, and high-risk individuals (p &lt; 0.05). Persons who were female at birth were at a higher risk of HIV infection than people who were male at birth. Final models were integrated in a tool that can assess person-specific risk and simulate cumulative HIV risk over time. These models can be used to optimize future PrEP clinical trials by identifying potential participants at highest risk.

Invasive pneumococcal disease remains one of the leading causes of morbidity and mortality worldwide. In Russia, 13- valent pneumococcal conjugate vaccine (PCV13) was introduced into the childhood immunization programme nationwide in 2014. As part of the Global Pneumococcal Sequencing Project (GPS), we used genome data to characterize 179 pneumococcal isolates collected from Russia in 2011-2018 to investigate the circulating pneumococcal strains using a standardized genomic definition of pneumococcal lineages (global pneumococcal sequence clusters, GPSCs), prevalent serotypes and antimicrobial resistance profiles.We observed high serotype and lineage diversity among the 179 isolates recovered from cerebrospinal fluid (n=77), nasopharyngeal swabs (n=99) and other non-sterile site swabs (n=3). Overall, 60 GPSCs were identified, including 48 clonal complexes (CCs) and 14 singletons, and expressed 42 serotypes (including non-typable). Among PCV13 serotypes, 19F, 6B and 23F were the top three serotypes while 11A, 15B/C and 8 were the top three among non-PCV13 serotypes in the collection. Two lineages (GPSC6 and GPSC47) expressed both PCV13 and non-PCV13 serotypes that caused invasive disease, and were penicillin- and multidrug-resistant (MDR), highlighting their potential to adapt and continue to cause infections under vaccine and antibiotic selective pressure. PCV13 serotypes comprised 92 % (11/12) of the CSF isolates from the children aged below 5 years; however, the prevalence of PCV13 serotype isolates dropped to 53 % (31/58) among the nasopharyngeal isolates. Our analysis showed that 59 % (105/179) of the isolates were predicted to be non-susceptible to at least one class of antibiotics and 26 % (46/179) were MDR. Four MDR lineages (GPSC1, GPSC6, GPSC10 and GPSC47) accounted for 65 % (30/46) of the MDR isolates and expressed PCV13 serotypes (93 %, 28/30).This study provides evidence of high genetic and serotype diversity contributed by a mix of globally spreading and regionally circulating lineages in Russia. The observations suggest that the PCV13 vaccine could be important in reducing both invasive disease and antimicrobial resistance. We also identify potential lineages (GPSC6 and GPSC47) that may evade the vaccine.

The disruptions of the coronavirus disease 2019 (COVID-19) pandemic impacted the delivery and utilization of healthcare services with potential long-term implications for population health and the hospital workforce. Using electronic health record data from over 700 USacute care hospitals, we documented changes in admissions to hospital service areas (inpatient, observation, emergency room [ER], and same-day surgery) during 2019-2020 and examined whether surges of COVID-19 hospitalizations corresponded with increased inpatient disease severity and death rate. We found that in 2020, hospitalizations declined by 50% in April, with greatest declines occurring in same-day surgery (-73%). The youngest patients (0-17) experienced largest declines in ER, observation, and same-day surgery admissions; inpatient admissions declined the most among the oldest patients (65+). Infectious disease admissions increased by 52%. The monthly measures of inpatient case mix index, length of stay, and non-COVID death rate were higher in all months in 2020 compared with respective months in 2019.

During 2020, an estimated 150,000 persons aged 0-14 years acquired HIV globally (1). Case identification is the first step to ensure children living with HIV are linked to life-saving treatment, achieve viral suppression, and live long, healthy lives. Successful interventions to optimize pediatric HIV testing during the COVID-19 pandemic are needed to sustain progress toward achieving Joint United Nations Programme on HIV/AIDS (UNAIDS) 95-95-95 targets.* Changes in HIV testing and diagnoses among persons aged 1-14 years (children) were assessed in 22 U.S. President's Emergency Plan for AIDS Relief (PEPFAR)-supported countries during October 1, 2019-September 30, 2020. This period corresponds to the two fiscal quarters before the COVID-19 pandemic (i.e., Q1 and Q2) and the two quarters after the pandemic began (i.e., Q3 and Q4). Testing was disaggregated by age group, testing strategy, and fiscal year quarter. During October 2019-September 2020, PEPFAR supported 4,312,343 HIV tests and identified 74,658 children living with HIV (CLHIV). The number of HIV tests performed was similar during Q1 and Q2, decreased 40.1% from Q2 to Q3, and increased 19.7% from Q3 to Q4. The number of HIV cases identified among children aged 1-14 years (cases identified) increased 7.4% from Q1 to Q2, decreased 29.4% from Q2 to Q3, and increased 3.3% from Q3 to Q4. Although testing in outpatient departments decreased 21% from Q1 to Q4, testing from other strategies increased during the same period, including mobile testing by 38%, facility-based index testing (offering an HIV test to partners and biological children of persons living with HIV) by 8%, and testing children with signs or symptoms of malnutrition within health facilities by 7%. In addition, most tests (61.3%) and cases identified (60.9%) were among children aged 5-14 years (school-aged children), highlighting the need to continue offering HIV testing to older children. These findings provide important information on the most effective strategies for identifying CLHIV during the COVID-19 pandemic. HIV testing programs should continue to use programmatic, surveillance, and financial data at both national and subnational levels to determine the optimal mix of testing strategies to minimize disruptions in pediatric case identification during the COVID-19 pandemic.

While mixed methods research can enhance studies of intervention outcomes and projects where research itself transforms communities through participatory approaches, methodologists need explicit examples. As the field of interpersonal violence prevention increasingly embraces community-level prevention strategies, it may benefit from research methods that mirror community-building prevention processes. A multiphase mixed methods study with sequential and convergent components assessed the feasibility, and impact of a prevention program to change social norms and increase collective efficacy in towns. Joint display analysis created a nuanced picture of the acceptability, feasibility, and impact of the program. This article contributes to the field of mixed methods research by bridging discussions of “interventionist” studies with models of community-based participatory mixed methods research into a combined community-engaged method. © The Author(s) 2022.

BACKGROUND: Racial and ethnic variations in attribution of cervical precancer and cancer to HPV types may result in different HPV vaccine protection, screening test coverage, and clinical management. METHODS: Pooling data from seven U.S. studies, we calculated the proportional attribution of precancers and cancers to HPV types using HPV DNA typing from diagnosis. All statistical tests were 2-sided. RESULTS: For all racial and ethnic groups, most cervical intraepithelial neoplasia grade 3 (CIN3) (n=5,526) and squamous cell carcinoma (SCC) cases (n=1,138) were attributed to types targeted by the 9-valent vaccine. A higher proportion of CIN3s were attributed to non-vaccine HPV types among non-Hispanic Black women (15.8%) compared with non-Hispanic Asian or Pacific Islander (9.7%, P=.002), non-Hispanic White (9.2%, P<.001), and Hispanic women (11.3%, P=.004). The proportion of SCCs attributed to 9-valent types was similar by race and ethnicity (90.4%-93.8%, P=.80). A higher proportion of CIN3s were attributed to non-vaccine HPV35 among non-Hispanic Black (9.0%) compared with non-Hispanic Asian or Pacific Islander (2.2%), non-Hispanic White (2.5%), and Hispanic women (3.0%, all P<.001). Compared with CIN3, the proportion of SCCs attributed to HPV35 among Non-Hispanic Black women (3.2%) was lower and closer to other groups (0.3%-2.1%, P=.70). CONCLUSION: The 9-valent HPV vaccine will prevent nearly all cervical precancers and invasive cancers among major racial and ethnic groups in the United States. Adding HPV35 to vaccines could prevent a small percentage of CIN3s and SCCs, with greater potential impact for CIN3s among Black women. HPV screening tests target high-risk HPV types, including HPV35. Future genotyping triage strategies could consider the importance of HPV35 and other HPV16 related types.
