BACKGROUND:Incidence estimates of post-acute sequelae of SARS-CoV-2 infection, also known as long-COVID, have varied across studies and changed over time. We estimated long-COVID incidence among adult and pediatric populations in three nationwide research networks of electronic health records (EHR) participating in the RECOVER Initiative using different classification algorithms (computable phenotypes). METHODS:This EHR-based retrospective cohort study included adult and pediatric patients with documented acute SARS-CoV-2 infection and two control groups-- contemporary COVID-19 negative and historical patients (2019). We examined the proportion of individuals identified as having symptoms or conditions consistent with probable long-COVID within 30-180 days after COVID-19 infection (incidence proportion). Each network (the National COVID Cohort Collaborative (N3C), National Patient-Centered Clinical Research Network (PCORnet), and PEDSnet) implemented its own long-COVID definition. We introduced a harmonized definition for adults in a supplementary analysis. RESULTS:Overall, 4% of children and 10-26% of adults developed long-COVID, depending on computable phenotype used. Excess incidence among SARS-CoV-2 patients was 1.5% in children and ranged from 5-6% among adults, representing a lower-bound incidence estimation based on our control groups. Temporal patterns were consistent across networks, with peaks associated with introduction of new viral variants. CONCLUSION/CONCLUSIONS:Our findings indicate that preventing and mitigating long-COVID remains a public health priority. Examining temporal patterns and risk factors of long-COVID incidence informs our understanding of etiology and can improve prevention and management.

BACKGROUND:Use of party drugs is common among nightclub attendees, but more information is needed regarding both intentional use and unknown exposure to synthetic cathinones, fentanyl, and xylazine in this high-risk population. METHODS:Throughout 2024, participants attending nightclubs in New York City were surveyed and had their saliva analyzed for drug exposure using targeted and untargeted analysis (n = 1024). We calculated the prevalence of synthetic cathinone, fentanyl, and xylazine exposure overall and in relation to demographic and drug use characteristics. RESULTS:11 (1.1 %) tested positive for one or more synthetic cathinones, 1.5 % (n = 15) tested positive for fentanyl or its precursor (4-ANPP), and 4 (0.4 %) tested positive for xylazine. All but one exposure to fentanyl was linked to unreported past-month use (93.3 %) and 54.5 % of synthetic cathinone exposures were linked to unreported past-month use (ps<.05). Three of four participants (75.0 %) testing positive for xylazine also tested positive for fentanyl exposure. Most (n = 8) synthetic cathinone exposures involved methylmethcathinone (MMC), and there were also detections of chloromethcathinone (CMC, n = 4), N-N-dimethylpentylone (n = 2), N-ethylpentylone (n = 2), and eutylone (n = 2). Compared to those testing positive for synthetic cathinones, those testing positive for fentanyl were more likely to identify as heterosexual and/or test positive for prescription opioid use, and less likely to have a college degree or to test positive for MDMA use (ps<.05). CONCLUSIONS:Unintentional exposure to these drugs is occurring, often because they have been added as adulterants in more common drugs. Results can inform prevention and harm reduction education in this population and in the general population.

BACKGROUND:Falls are thought to be common in patients undergoing maintenance hemodialysis, but little is known about their frequency or outcomes. In this prospective study, we sought to increase our knowledge regarding the incidence, timing, circumstances, and outcomes of falls in this population. METHODS:Between January 2021 and April 2023, adults undergoing maintenance hemodialysis from 103 U.S. dialysis facilities were enrolled in the HOPE Consortium trial, which randomized participants with moderate or severe chronic pain to a pain coping skills cognitive behavioral therapy intervention or usual care. Occurrence of falls was a pre-specified trial outcome. The research team inquired about falls at each four-week follow-up visit during the 36-week study. Multivariable regression was used to explore associations of demographic and clinical characteristics, including patient-reported symptoms, with fall risk. RESULTS:Of 643 trial participants, 178 (28%) experienced 293 falls over a cumulative follow-up period of 429 participant-years for an overall rate of 0.68 falls per participant-year (95% CI: 0.61, 0.76). Accidents were the most frequent cause of falls (38%). It was rare for falls to be related to the hemodialysis treatment or to occur in the hemodialysis unit. Of the 293 falls, 36 (12%) were evaluated in the emergency department without subsequent hospitalization, 41 (14%) resulted in a hospital admission, and 19 (7%) led to a fracture. In multivariable analyses, neither demographic characteristics severity of pain symptoms or medication use such as opioids at enrollment was associated with the fall risk. CONCLUSIONS:Falls were common in this cohort of maintenance hemodialysis patients with chronic pain, occurring in 28% of individuals during a planned follow-up of 36 weeks. Falls rarely occurred in the dialysis unit, with the vast majority occurring at participants' homes and due to accidental causes. There was no significant association between patient-reported symptoms or medication use and the risk of subsequent falls. TRIAL REGISTRATION/BACKGROUND:NCT04571619.

OBJECTIVES/OBJECTIVE:To evaluate whether parents who assess their infants as more developmentally advanced are more likely to begin feeding their infants complementary foods before 6 months, and whether developmental readiness explains racial and ethnic differences in complementary food introduction. STUDY DESIGN/METHODS:In a cohort of mothers of 5475 infants from New York state, 9 markers of infant development and timing of initiating complementary feeding were assessed. Mixed effect models assessed associations between developmental markers and initiation of complementary feeding before 6 months term-corrected age. Direct and indirect effects of racial and ethnic differences in complementary feeding through a total development score were computed. RESULTS:In a fully adjusted model, infant sitting (adjusted odds ratio [aOR]:1.60, 95% CI:1.32, 1.93), head control (aOR:1.51, 95% CI:1.26, 1.81), reaching (aOR:1.19, 95% CI:1.04, 1.37), mouthing (aOR:1.26, 95%CI:1.08, 1.46), and having a good appetite (aOR:1.61, 95%CI:1.15, 2.24) were uniquely associated with complementary feeding before age 6 months. A 1-point increase in a total development score was also associated with higher odds of complementary feeding (aOR:1.26, 95% CI:1.19, 1.33). The development score explained some racial and ethnic differences in the odds of complementary feeding before 6 months. CONCLUSIONS:Results suggest that parents are using their children's developmental markers to decide when to begin complementary feeding. Furthermore, observations of racial and ethnic differences in the timing of complementary feeding may be explained by perceptions of developmental readiness, in line with recommendations. Future research on complementary feeding should incorporate assessments of infant developmental readiness.

BACKGROUND:The 2022-2023 global mpox outbreak predominantly affected sexual minority men, with notable racial/ethnic disparities in the USA. While the current literature has established the clinical predictors of severe mpox disease, little is known about the role of insurance status on clinical outcomes. We sought to characterize patients diagnosed with mpox in New York City (NYC) and examine associations between insurance status and mpox severity score (mpox-SS). METHODS:), prior vaccination with JYNNEOS or a smallpox vaccine, presence of a sexually transmitted infection (STI), and CDC Social Vulnerability Index. RESULTS:The mean age (SD) was 38.3 (10.2) years with 53 (37.1%) identifying as non-Hispanic White, 44 (30.8%) as Hispanic/Latino, and 30 (20.9%) as non-Hispanic Black. Over 90% were male sex at birth or identified as cisgender men and approximately 80% were sexual minority men. Ninety-six (67.1%) had private insurance, 6 (4.2%) Medicare, 35 (24.5%) Medicaid, and 4 were (2.8%) uninsured. Sixty-three (44.1%) had a confirmed HIV diagnosis, 25 (17.4%) patients had prior JYNNEOS vaccination, and 31 (21.7%) had a high-risk condition. Thirty-eight (26.6%) patients received tecovirimat; 21 (14.7%) patients were hospitalized, with 4 (2.8%) of those admitted to the ICU. The mean (SD) mpox-SS was 6.85 (3.36). In univariate analysis, lack of insurance or Medicaid status was associated significantly with more severe mpox-SS. Insurance status remained significant (p = 0.03) in multivariable models. CONCLUSIONS:Being uninsured or on Medicaid was significantly associated with a higher mpox-SS in this diverse cohort of predominantly cisgender sexual minority men in NYC. High-risk status and lack of prior vaccination were associated with higher mpox-SS. Further studies are needed to assess the relationship between insurance, delays in access to care, or other socioeconomic inequities with severe mpox to understand the inequities beyond insurance access to prevent disparities in future outbreaks.

BACKGROUND:Individuals involved in the criminal legal system represent one of the most disproportionately affected populations in the opioid overdose crisis. Despite evidence of medications for opioid use disorder (MOUD) reducing overdose mortality, illicit opioid use, and recidivism, most correctional facilities do not offer these treatments. Sublocade and Brixadi, two distinct, branded, formulations of extended-release buprenorphine (XR-B), offer a promising approach to improving MOUD treatment adherence and reducing post-release overdose deaths. METHODS:This hybrid pilot study will utilize a partially randomized preference trial (PRPT) design to compare the preliminary effectiveness, feasibility, acceptability and other outcomes between Sublocade and Brixadi initiation. We aim to enroll 60 incarcerated individuals with opioid use disorder who are interested in XR-B and have a scheduled release within 120 days. Participants will choose their preferred injectable treatment or, if ambivalent, be randomly assigned. All participants will receive monthly XR-B injections pre-release and continue for three months post-release, with additional administrative follow-up for another three months. The primary outcome is post-release treatment retention; other outcomes will be assessed using the Proctor taxonomy. Data will be collected using clinical assessments, surveys, and administrative databases. DISCUSSION/CONCLUSIONS:This study explores differences in XR-B formulations during the high-risk time of transition out of prison. It combines a hybrid implementation science and preference trial design-two methodologies that can help address the specific challenges of research in carceral environments. By understanding implementation of XR-B in a prison setting, findings can provide valuable insights to guide other facilities in adopting this life-saving treatment.

Preterm birth can significantly impact cognitive development, particularly executive functions (EF). This study investigated hot (with emotional/motivational aspects) and cool (purely neutral/cognitive) EF trajectories in preterm and full-term children, examining brain-behavior relationships. It included 3508 participants aged 9-10 years (mean age 10.0 years) at baseline from the Adolescent Brain and Cognitive Development (ABCD®) study, evenly split between preterm and full-term births (54.36 % males; 1.05 % Asian American, 10.69 % Black, 15.68 % Hispanic, 61.57 % White, 11.09 % other). Participants were followed for 4 years, completing MRI scans and a cool EF task at baseline and at the 2-year follow-up, as well as hot/cool and hot EF tasks at the 1- and 3-year follow-ups. Linear mixed models showed varying effects of preterm birth across the different EF tasks. Specifically, preterm children showed persistent cool EF deficits and a catch-up pattern for hot EF, while performance on the hot/cool task showed no association with preterm birth. Brain-behavior bivariate latent change score analyses identified distinct bidirectional relationships in specific regions, suggesting altered cognitive-brain maturation interactions in preterm children. These findings highlight the complex nature of EF development following preterm birth: while cool EF deficits persist, hot EF shows catch-up growth in preterm children during early adolescence. This emphasizes the need for tailored interventions and long-term follow-up in this population.

BACKGROUND:Potential rural-urban differences in prostate cancer care are understudied, particularly regarding the utilization of advanced diagnostic tests. Herein we examined variations in Positron Emission Tomography (PET) utilization for prostate cancer care, including diagnosis, staging and treatment planning, across residential regions in the United States. METHODS:Patients newly diagnosed with prostate cancer between 2019 and 2021 and post-diagnostic PETs were identified using full Medicare claims data. PET use was assessed in all newly diagnosed patients, though indications vary by risk. Patients' counties were categorized as metro, urban, or rural, from most to least urbanized. Regional PET utilization was further examined at the level of hospital referral regions. A multivariable logistic regression model was performed to assess the impact of rurality on PET imaging. A secondary analysis included an interaction term for race to explore the effect of residence on PET imaging by racial group. RESULTS:Overall, 495 865 patients were included in the analysis: 393 861 (79.4%) lived in metro, 56 698 (11.4%) in urban and 39 707 (8.0%) in rural counties. Patients in metro counties underwent PET imaging more often (8.4%) than patients in urban (7.3%) or rural counties (7.2%), p < 0.0001. At a level of hospital referral region, PET utilization rates ranged from 2.2 to 20.8%. PET imaging was more commonly performed in White compared to Black or Hispanic patients. Rural patients were less likely to undergo PET imaging compared to metro patients (odds ratio [OR] 0.87, 95% Confidence interval [CI]: 0.82-0.92 p < 0.0001). Rural Black (OR 0.69, 95%CI 0.57-0.83, p < 0.0001) and rural White patients (OR 0.89, 95%CI 0.83-0.94 p < 0.0001) were less likely to obtain PET imaging compared to their metro counterparts, p-interaction < 0.0001. CONCLUSION/CONCLUSIONS:Rural patients were less likely to undergo PET imaging than metro patients. The effect of rurality was most pronounced among Black patients. Our findings underscore the need for strategies to support equitable use of PET imaging.

BACKGROUND:Inclusion of patients, caregivers, and community members in scientific research should be essential for patient-centered care. Patients’ lived experiences can propose new areas of focus that may not have previously been considered, ensure that potentially sensitive topics are addressed thoughtfully, contribute to the interpretation of findings, and identify future directions of research. Further, their inclusion in the drafting of manuscripts can ensure that research findings are translatable to real-world practice. To achieve this goal, the Researching COVID to Enhance Recovery (RECOVER) consortium developed a Representative Authorship system for development of scientific manuscripts that report RECOVER data. This paper describes a Quality Improvement (QI) project that was conducted to identify system strengths and improvement opportunities. METHODS:An online QI survey was distributed to RECOVER’s Representative Authors about a year into the implementation of the Representative Authorship System. The survey focused on several key aspects, including the clarity regarding the authorship process, training opportunities, the matching process, communication within writing groups, and the perceived impact of the representative engagement on the quality and applicability of research. The survey also explored participants’ satisfaction with compensation, support, and involvement in the system, as well as areas for improvement. RESULTS:The survey was sent to 49 representative authors with 17 respondents (35%). Most respondents reported positive experiences, highlighting the effective matching to manuscripts based on their expertise and the perceived positive impact of their involvement on research outcomes. Additionally, participants felt that including diverse voices enhanced the relevance of research for clinical practice. Several areas for improvement were identified, including communication challenges within writing groups, the utility of manuscript orientation calls, and the fairness of compensation. Respondents also indicated a need for more training opportunities and logistical support. CONCLUSIONS:RECOVER’s Representative Authorship system is effective in fostering collaboration and improving the inclusivity of scientific research. The survey findings indicate that there are logistical changes around communication, training, and compensation that could enhance the experience for all collaborators. Based on these findings, we plan to implement changes to improve awareness, understanding, and collaboration. Additional work is needed to solicit feedback from investigators and administrative staff to obtain a more holistic understanding of the system.

BACKGROUND:Healthy Days at Home (HDaH) is a patient-centered outcome measure quantifying the number of days individuals spend at home without hospitalizations or emergency department (ED) visits, while maintaining functional independence. This study examines the association between HDaH and prognosis among US older adults with serious life-limiting illnesses (commonly heart failure, chronic obstructive pulmonary disease, advanced cancer, and end-stage kidney disease) and explores how this relationship differs by cancer status. METHODS:For this prospective cohort design study, we pooled Medicare Claims data of older adults (aged 66 or greater) with serious life-limiting illnesses who visited one of 30 EDs participating in the Primary Palliative Care for Emergency Medicine study between 2015 and 2019. The main exposure was prognosis, measured using the Gagne index, a short-term predictor of mortality. We controlled for age, sex, race/ethnicity, and used cancer diagnosis as a secondary predictor and stratification variable. The outcome, HDaH, was defined as 180 days minus the days a patient spent in healthcare institutions, including hospitals, skilled nursing facilities, and hospice care. We used generalized linear mixed-effects models with a log (180) offset to estimate the adjusted rate ratios (aRR) and 95% confidence intervals. RESULTS:The cohort included 122,579 seriously ill older adults,11% (n = 13,452) of whom had cancer. The median (IQR) HDaH was 115 (26-174) days. Each unit increase in Gagne index score was associated with a 6.0% decrease in the rate of HDaH (aRR: 0.94; 95% CI: 0.94 to 0.94), a pattern observed in both cancer and non-cancer groups. Cancer diagnosis was associated with 7.0% increase in HDaH (aRR: 1.07; 95% CI: 1.07 to 1.07). CONCLUSION/CONCLUSIONS:While poor prognosis is associated with fewer healthy days at home, cancer diagnosis is associated with more healthy days at home. Our findings highlight the need for tailored care models to reduce hospitalizations and increase HDaH for patients with serious life-limiting illnesses other than cancer.
