BACKGROUND:HIV status disclosure remains a major challenge among children living with perinatally acquired HIV with many taking treatment up to adolescence without knowing their serostatus. This non-disclosure is influenced by factors like fear of the negative consequences of disclosure. Since HIV status disclosure has been found to have good effects including improving treatment adherence and better mental health outcomes, there is a need to design interventions aimed at improving disclosure rates among children living with HIV. This study aims at adapting a clinic-based pediatric HIV status disclosure intervention and tasking shifting from healthcare workers to caregiver peer supporters in Eastern Uganda. METHODS:The adaptation process involved consultations with caregivers, healthcare workers involved in the care of children living with HIV, researchers in this field, intervention developers, and other experts and stakeholders. This was done through conducting FGDs with HCWs, caregivers, and peer supporters and consultations with researchers in the field of HIV. The original intervention manual was translated to Lusoga which is the commonly spoken dialect in this region. Collected qualitative data were analyzed using an inductive approach to develop themes and subthemes. Written informed consent will be obtained from all participants before participation in the study. RESULTS:A total of 28 participants were involved in the FGDs, while two pediatricians and two HIV researchers/specialists were consulted. Six themes were generated in relation to all suggested changes to the original manual which were related to: (1) sociocultural beliefs/norms/perceptions (5 FGDs), (2) boosting caregiver's confidence for disclosure (5FGDs), (3) disclosure mode, environment, and person (4 FGDs), (4) health facility/system related changes (3 FGDs), (5) reorganization/paraphrasing (3FGDs) and (6) age appropriateness (2FGDs). CONCLUSION/CONCLUSIONS:This study emphasized that whereas some aspects of intervention can apply to various contexts, there is a need for cross-cultural adaptation of interventions before being implemented in settings where they were not developed.

INTRODUCTION/BACKGROUND:Vaping of nicotine and cannabis has increased substantially among US adults, but its impact on workplace productivity remains poorly understood. This study examines the associations between nicotine and cannabis vaping patterns and workplace absenteeism. METHODS:Cross-sectional data from a US nationally representative sample of noninstitutionalized part-time and full-time employed adults aged ≥ 18 from the 2022 National Survey on Drug Use and Health (N = 30,591) were analyzed. The associations between nicotine vaping (recency and frequency), cannabis vaping (recency), and workplace absenteeism (measured by self-reported number of missed days due to illness/injury and skipped work in the past month) were evaluated using negative binomial regression adjusting for sociodemographic characteristics and other past-month drug use. RESULTS:An estimated 10.4 % of full-time workers vaped nicotine in the past month and 6.4 % vaped cannabis. Compared to never-vapers of nicotine, those with any history of vaping had higher estimated incidence of absences with past-month vaping associated with increased incidence of missed work due to illness/injury (aIRR = 1.34, 95 % CI: 1.14-1.59) and skipping work (aIRR = 1.65, 95 % CI: 1.24-2.21). Past-month cannabis vaping was associated with increased estimated incidence of missed work due to illness/injury (aIRR = 1.35, 95 % CI: 1.06-1.72) and skipping work (aIRR = 1.70, 95 % CI: 1.32-2.18), although these rates did not differ significantly from those associated with non-vaped cannabis use. Associations were generally stronger among full-time workers compared to part-time workers. CONCLUSION/CONCLUSIONS:Both nicotine and cannabis vaping are associated with increased workplace absenteeism. Results support the development and implementation of workplace policies to address vaping-related productivity losses.

BACKGROUND:To encourage high-quality, reduced-cost care for total joint arthroplasty (TJA), the Centers of Medicare & Medicaid Services mandated a pay-for-performance model, the Comprehensive Care for Joint Replacement (CJR), as part of the Patient Protection and Affordable Care Act (PPACA). The CJR incentivizes cost containment, and it was anticipated that its implementation would reduce access to TJA for high-cost populations. Patients with end-stage kidney disease (ESKD) undergoing kidney replacement therapy (dialysis and kidney transplant) are costly compared with healthier patients, but it was unknown whether this population lost access to hip and knee replacement because of CJR implementation. This population allows study of whether TJA is accessible for medically complex patients whose risk of surgical complications has been mitigated, as kidney transplantation improves outcomes compared with dialysis, allowing evaluation as to whether access improved when patients crossed over from dialysis to transplantation. Because all patients with ESKD are included in a mandated national registry, we can quantify whether access changed for patients who underwent dialysis and transplantation. QUESTIONS/PURPOSES/OBJECTIVE:(1) How did the rate of TJA change amid the shift to bundled payments for patients with ESKD receiving dialysis? (2) How did the rate of TJA change amid the shift to bundled payments for patients with ESKD after kidney transplant? METHODS:This was an observational cohort study from 2008 to 2018 using the United States Renal Data System, a mandatory national registry that allows for the opportunity to study all individuals with ESKD. During the study period, we identified 1,324,614 adults undergoing routine dialysis and 187,212 adult kidney transplant recipients; after exclusion for non-Medicare primary insurance (n = 785,224 for dialysis and 78,011 for transplant), patients who were 100 years or older (n = 79 and 0, respectively), those who resided outside of 50 US states and Puerto Rico (n = 781 and 87, respectively), missing dialysis status for the dialysis cohort (n = 8658), and multiorgan transplant recipients for the transplant cohort (n = 2442), our study population was 40% (529,872) of patients who underwent routine dialysis and 57% (106,672) of adult kidney transplant recipients, respectively. TJA was ascertained using Medicare Severity Diagnosis Related Groups and ICD-9 and ICD-10 codes. We divided the study period by PPACA (January 1, 2014, to March 31, 2016) and CJR (April 1, 2016, to December 31, 2018) implementation and compared the incidence of TJA by era using mixed-effects Poisson regression adjusting for calendar time and clinical and demographic variables. RESULTS:After adjustment for linear temporal trend and patient case mix, there was no evidence of association between policy implementation and the incidence of TJA. In the dialysis cohort, the adjusted incidence rate ratio (IRR) for TJA was 1.06 (95% confidence interval [CI] 0.98 to 1.14; p = 0.2) comparing PPACA with the previous period and 1.02 (95% CI 0.96 to 1.08; p = 0.6) comparing CJR with the previous periods. Similarly, in the transplant cohort, the adjusted IRR for TJA was 0.82 (95% CI 0.67 to 1.02; p = 0.07) comparing PPACA with the previous period and 1.10 (95% CI 0.94 to 1.28; p = 0.9) comparing CJR with the previous periods. CONCLUSION/CONCLUSIONS:There was no loss in access to TJA for medically complex patients receiving kidney replacement therapy. The increase in TJA incidence for patients after kidney transplant and decrease for patients receiving dialysis suggest that surgeons continued to provide care for higher risk patients whose risk of morbidity or mortality with total joint replacement has been maximally improved after transplantation. LEVEL OF EVIDENCE/METHODS:Level III, prognostic study.

BACKGROUND:Permanent supportive housing (PSH) is the gold standard intervention for chronic homelessness, but PSH tenants face high risk for overdose due to a combination of individual and environmental risk factors. Little research has examined overdose prevention in PSH. METHODS:We conducted baseline surveys with staff from 20 New York PSH buildings participating in an overdose prevention technical assistance intervention study. PSH staff from participating buildings were invited via email to complete a brief online survey about their knowledge of overdose and perspectives on implementing overdose prevention practices in PSH. RESULTS:Surveys were completed by 178 staff of 286 invitations sent (response rate 62.2%). Average score on the Brief Opioid Overdose Knowledge (BOOK) questionnaire was 8.62 (SD 2.64) out of 12 points. Staff felt very positively (91.6-97.2% agreed or completely agreed) regarding the appropriateness and acceptability of implementing overdose prevention practices in PSH, but less certain about the feasibility of implementing these practices (62.4-65.5% agreed or completely agreed). Most (77.3%) felt it was mostly or definitely true that overdose prevention was a top priority in their building. Most PSH staff (median = 85.0%) but fewer tenants (median = 22.5%) had received a naloxone kit and training in overdose response. CONCLUSION/CONCLUSIONS:Staff feel positively about the acceptability and appropriateness of implementing overdose response practices in PSH, but somewhat more uncertain about the feasibility of implementing these practices. This study's results help hone targets for interventions to help PSH buildings take steps to reduce tenant overdose risk.

The concept of 'food justice' recognizes the systemic injustices embedded in the U.S. food system and the urgent need for transformative policies to ensure equitable access to affordable, nutritious, and culturally relevant food. Limited access to these foods drives food insecurity and increases the prevalence of diet-related diseases in low-income and minority communities. Dominant narratives that individualize hunger and food insecurity often blame the individual and overlook the underlying structural factors that sustain these issues. These narratives have considerable influence. They shape public opinion and can also guide policy decisions. This commentary explores the goals of the food justice movement in the U.S., describes how the food and racial justice movements intersect, and examines the role of commercial marketing and public policy in shaping the food justice discourse. We also reflect on the efforts that should be made to reframe these dominant narratives and facilitate meaningful change in the food environment.

Natural selection on complex traits is difficult to study in part due to the ascertainment inherent to genome-wide association studies (GWAS). The power to detect a trait-associated variant in GWAS is a function of frequency and effect size - but for traits under selection, the effect size of a variant determines the strength of selection against it, constraining its frequency. Recognizing the biases inherent to GWAS ascertainment, we propose studying the joint distribution of allele frequencies across populations, conditional on the frequencies in the GWAS cohort. Before considering these conditional frequency spectra, we first characterized the impact of selection and non-equilibrium demography on allele frequency dynamics forwards and backwards in time. We then used these results to understand conditional frequency spectra under realistic human demography. Finally, we investigated empirical conditional frequency spectra for GWAS variants associated with 106 complex traits, finding compelling evidence for either stabilizing or purifying selection. Our results provide insight into polygenic score portability and other properties of variants ascertained with GWAS, highlighting the utility of conditional frequency spectra.

Previous studies have demonstrated that text message reminders can improve pediatric vaccination rates, including low income & diverse settings such as those served by federally qualified health centers. In this study, we aimed to improve compliance with routine childhood immunizations via a text message intervention in a network of urban, federally qualified health centers at a large academic medical center. We targeted parents or guardians of children aged 0-2 years who were overdue or due within 14 days for at least one routine childhood immunization without a scheduled appointment. In Round 1, two versions of a text were compared to a control (no text). In subsequent Rounds, a new text was compared to a control (no text). In each round the content, wording, and frequency of texts changed. Subjects were randomized to receive a text (treatment group(s)) or to not receive a text (control group) in each round between 2020 and 2022. The primary outcome was whether overdue vaccines had been given by 12 week follow up. The secondary outcome was appointment scheduling within the 72 hours after text messages were sent. In Round 1 (n=1203) no significant differences were found between groups in overdue vaccine administration per group or per patient at follow up, or in appointment scheduling. In Round 2 (n=251) there was no significant difference in vaccine administration per group or per patient. However, significantly more patients in the intervention group scheduled an appointment (9.1% vs. 1.7%, p=0.01). In Round 3 (n=1034), vaccine administration was significantly higher in the intervention group compared to the control overall (7.0% vs. 5.5%, 0.016) and per subject (p=0.02). Significantly more patients in the intervention group scheduled an appointment compared to the control (3.3% vs. 1.2%, p=0.02). We found that text messaging can be an effective intervention to promote health service utilization such as pediatric vaccination rates, which although improved in this study, remain low.

PURPOSE/OBJECTIVE:The Veterans Affairs Health Administration (VA) has experience using telehealth (TH) to deliver care to 10 million enrolled Veterans for many clinical care needs. The VA National TeleOncology Service (NTO) was established in 2020 to provide specialized cancer services regardless of geography. We sought to compare quality in TH-delivered cancer services with traditional (TR) in-person VA care. METHODS:Using electronic health record data, we identified patients with an International Classification of Diseases-10 diagnostic code for an incident malignancy from December 2016 to March 2021 at early adopting sites providing both TR and TH care. We classified patients as TH users if they received TH services at least once for their cancer care. We gathered demographic, clinical, and treatment characteristics to calculate 25 Quality Oncology Practice Initiative (QOPI) measures in the symptoms and toxicity management (two), end of life and palliative care (10), and core measure domains (13). We report disease-specific measures, QOPI measures descriptively, and performed chi-square tests to compare TH and TR. RESULTS:= .002). TH and TR rates were similar for the other QOPI measures. CONCLUSION/CONCLUSIONS:VA is a leader in TH cancer care because of both its volume and quality. VA-provided TH cancer care quality is similar to or better than that of TR in-person care. NTO specifically, and VA teleoncology broadly, provides another option to Veterans for cancer care.

BACKGROUND:Disruption of ambulatory healthcare in New York City (NYC) during the COVID-19 pandemic was common, but the impact on the cardiometabolic health of vulnerable patient groups is unknown. Therefore, we estimated the effect of total care disruption (TCD) on blood pressure (BP) control among older NYC residents with hypertension and at least one other chronic condition, and examined whether neighborhood poverty moderated this impact. METHODS:From the INSIGHT Clinical Research Network, we identified NYC residents ≥50 years of age with hypertension and at least one other chronic condition. TCD was defined as no ambulatory or telehealth visit during the pandemic. We contrasted the change in prevalence of controlled BP (BP <140/90) before and after the pandemic among those with and without TCD via an inverse probability weighted (IPW) difference-in-difference regression model. RESULTS:Among 212,673 eligible individuals, mean age was 69.5 years (SD: 10.2 years) and 15.1% experienced TCD. BP control declined from 52.4% to 45.9% among those with TCD and from 53.6% to 48.9% among those without TCD. After IPW adjustment, a larger decline in BP control was noted among those with TCD (adjusted difference-in-difference = 1.13 percentage points (95% CI 0.32-1.94, p-value=0.0058)). There was no consistent difference in the relationship between TCD and post-pandemic BP control across neighborhood poverty levels. CONCLUSION/CONCLUSIONS:COVID-19-related TCD was associated with a modest decline in BP control among older adults with hypertension in NYC; this was not moderated by neighborhood poverty level.

OBJECTIVE:Anogenital distance (AGD) is a postnatal marker of in utero exposure to androgens and anti-androgens, and a predictor of reproductive health. We examined the association between gestational exposure to phthalates and AGD in male and female infants. METHODS:In 506 mother-infant pairs (276 males, 230 females), we measured urinary concentrations of phthalate metabolites at < 18 and 18-25 weeks of gestation and AGD at child age 12.9 months (95 % range 11.4-21.1). Phthalate metabolite concentrations were adjusted for urinary dilution, averaged, and natural log-transformed. We measured anus-clitoris distance (AGDac) and anus-fourchette distance (AGDaf) in females, and anus-scrotum distance, anus-penis distance, and penile width in males. We used linear regression and partial-linear single-index (PLSI) models to examine associations between phthalates and AGD as single pollutants and in mixture. RESULTS:Fifty-eight percent of mothers were Hispanic, followed by 27 % non-Hispanic White. Higher exposures to ∑di-isononyl(phthalate) (∑DiNP) was associated with longer AGDaf [1.28 mm (95 % confidence interval [CI]: 0.52, 2.03) and 0.97 mm (95 %CI: 0.25, 1.69), respectively]. Higher exposures to ∑di(2-ethylhexyl)phthalate (∑DEHP) was associated with longer AGDac [2.80 mm (95 %CI: 1.17, 4.44), and 1.90 mm (95 %CI: 0.76, 3.04), respectively]. No association was observed between phthalate metabolites and AGD in males after multiple testing correction. In mixture analyses, ∑DiNP and ∑DEHP were the main contributors to longer AGD in females. We also detected an interaction between ∑DiNP and ∑DEHP in association with AGD in females. CONCLUSION/CONCLUSIONS:Early pregnancy phthalate exposure was associated with longer AGD in female infants. Biological mechanisms underlying these associations should be further investigated.
