INTRODUCTION/BACKGROUND:). Clinical guidelines recommend multicomponent lifestyle programmes to promote modest, clinically significant body mass (BM) loss. Primary care providers (PCPs) often lack time to counsel and refer patients to intensive programmes (≥6 sessions over 3 months). Using peer coaches to deliver obesity counselling in primary care may increase patient motivation, promote behavioural change and address the specific needs of veterans. We describe the rationale and design of a cluster-randomised controlled trial to test the efficacy of the Peer-Assisted Lifestyle (PAL) intervention compared with enhanced usual care (EUC) to improve BM loss, clinical and behavioural outcomes (aim 1); identify BM-loss predictors (aim 2); and increase PCP counselling (aim 3). METHODS AND ANALYSIS/UNASSIGNED:We are recruiting 461 veterans aged 18-69 years with obesity or overweight with an obesity-associated condition under the care of a PCP at the Brooklyn campus of the Veterans Affairs NY Harbor Healthcare System. To deliver counselling, PAL uses in-person and telephone-based peer support, a tablet-delivered goal-setting tool and PCP training. Patients in the EUC arm receive non-tailored healthy living handouts. In-person data collection occurs at baseline, month 6 and month 12 for patients in both arms. Repeated measures modelling based on mixed models will compare mean BM loss (primary outcome) between study arms. ETHICS AND DISSEMINATION/UNASSIGNED:The protocol has been approved by the Institutional Review Board and the Research and Development Committee at the VA NY Harbor Health Systems (#01607). We will disseminate the results via peer-reviewed publications, conference presentations and meetings with stakeholders. TRIAL REGISTRATION NUMBER/BACKGROUND:NCT03163264; Pre-results.

Background/UNASSIGNED:Patients on maintenance hemodialysis are particularly vulnerable to infection and hospitalization from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Due to immunocompromised patients and the clustering that occurs in outpatient dialysis units, the seroprevalence of COVID-19 antibodies in this population is unknown and has significant implications for public health. Also, little is known about their risk factors for hospitalization. Methods/UNASSIGNED:nasopharyngeal, real-time, reverse-transcriptase PCR (RT-PCR); SARS-CoV-2 IgG seropositivity; hospitalization; and mortality. Results/UNASSIGNED:<0.001) compared with those who tested negative. Higher positivity rates were also observed among those who took taxis and ambulettes to and from dialysis, compared with those who used personal transportation. Antibodies were detected in all of the patients with a positive PCR result who underwent serologic testing. Of those that were seropositive, 32% were asymptomatic. The hospitalization rate on the basis of either antibody or PCR positivity was 35%, with a hospital mortality rate of 33%. Aside from COPD, no other variables were more prevalent in patients who were hospitalized. Conclusions/UNASSIGNED:We observed significant differences in rates of COVID-19 infection within three outpatient dialysis units, with universal seroconversion. Among patients with ESKD, rates of asymptomatic infection appear to be high, as do hospitalization and mortality rates.

BACKGROUND:Approximately half of male childhood cancer survivors experience fertility impairment, which can cause psychological distress. Sperm banking remains underutilized among adolescent males with cancer. Parent recommendation influences banking decisions, yet multi-informant studies have not been conducted to examine fertility preservation (FP) communication and decision making in this population. This study explored FP communication among mothers, fathers, and their male adolescents newly diagnosed with cancer. PROCEDURE/METHODS:Thirty-three male adolescents, 32 mothers, and 22 fathers completed semi-structured interviews 1-2 months after cancer diagnosis addressing this question: Tell me more about conversations you had about fertility preservation/sperm banking with your health care providers, parents/son, other family members, or anyone else. Interviews were audio-recorded and transcribed verbatim for thematic content analysis. RESULTS:Five process themes emerged: (1) reliance on health care team and social support networks to facilitate FP decisions (only parents); (2) withholding parental opinion and deferring the decision to the adolescent; (3) ease of communication (primarily adolescents); (4) communication barriers/facilitators; (5) not being present or not remembering details of FP conversations with health care providers (primarily fathers and adolescents). Four content themes included: (1) preference for biological (grand)parenthood; (2) consideration of adolescent's future partner's desire for biological parenthood (primarily parents); (3) banking while it is a viable option; (4) openness to alternative parenthood options (e.g., adoption/fostering, primary parents). CONCLUSIONS:Understanding variation in what family members discuss and consider relevant when making FP decisions is an important step toward improving pediatric oncofertility care. Interventions are needed to facilitate family FP-related conversations and optimize decisional satisfaction over time.

Most HIV research combines transgender women who have sex with men (TWSM) with cisgender men who have sex with men (MSM), despite emerging evidence of important differences. Using data from The MARI Study, we compared Black TWSM and Black cisgender MSM on personal and ecological factors. Black TWSM reported more unemployment (71.4% versus 51.4%, p = 0.015), incarceration (52.4% versus 36.0%, p = 0.046), stressful life experiences (median score 135.5 versus 90, p = 0.033), and HIV positivity (66.7% versus 22.9%, p = 0.008). Further research into the causes and consequences of these differences, and regarding TWSM specifically, is needed.

People who inject drugs (PWIDs) are a key population targeted in global efforts to increase HIV and Hepatitis C virus (HCV) diagnosis, linkage to care, and treatment retention. Colombia has experienced a significant increase in the incidence of HIV and HCV attributed to the alarming rise in injection drug use. The primary aim of this study was to identify factors influencing access to HIV and HCV care among PWIDs. Survey domains consisted of (1) sociodemographic characteristics; (2) history of HIV-HCV testing and infection status; (3) the 13-item questionnaire developed by Awad and colleagues to explore barriers to HIV and HCV testing, (4) the Barriers to Medical Care questionnaire; and (5) the Risk Assessment Battery. A total of 171 subjects completed the survey. A high proportion of participants reported past year testing for HIV (87%) and HCV (72.8%). However, most respondents elicited numerous barriers to obtaining information, referrals, and insurance coverage for accessing HIV and/or HCV care. Further studies are needed to identify scalable public health measures to overcome these barriers.

Objective/UNASSIGNED:To optimize the ability of hospitalized patients isolated due to COVID-19 to participate in physical therapy. Design/UNASSIGNED:This was a prospective, quality improvement trial of the feasibility and acceptability of a "hybrid" in-person and telerehabilitation platform to deliver physical therapy to hospitalized adults. Setting/UNASSIGNED:Inpatient wards of a tertiary care, multi-specialty academic medical center in the greater New York City metropolitan area. Participants/UNASSIGNED:A convenience sample of 39 COVID-19+ adults, mean age 57.3 years, 69% male, all previously community dwelling agreed to participate in a combination of in-person and telerehabilitation sessions (TR). Intervention/UNASSIGNED:Initial in-person evaluation by physical therapist followed by twice daily PT sessions, one in-person and one via a telehealth platform meeting Health Insurance Portability and Accountability Act (HIPAA) confidentiality requirements. The communication platform was downloaded to each participant's personal smart device to establish audiovisual contact with the Physical Therapist. Measures/UNASSIGNED:The 6-clicks Activity Measure for Post-Acute Care (AM-PAC) was used to score self-reported functional status pre-morbidly by, and by the therapist at baseline and discharge. Results/UNASSIGNED:Functional status measured by AM-PAC 6-clicks demonstrated improvement from admission to discharge. Barriers to participation were identified and strategies are planned to facilitate use of the platform in future. Conclusions/UNASSIGNED:A consistent and structured protocol for engaging patient participation in PT delivered via a telehealth platform was successfully developed. A process was put in place to allow for further development, recruitment and testing in a randomized trial.

BACKGROUND:Little is known regarding how the COVID-19 pandemic has affected patterns of drug use in the United States. Because drug seizures can serve as a proxy for drug availability, we examined shifts in drug seizures in the US during the pandemic. METHODS:We examined trends in seizures of marijuana, cocaine, methamphetamine, heroin, and fentanyl within five High Intensity Drug Trafficking Areas-Washington/Baltimore, Chicago, Ohio, New Mexico, and North Florida. Trends were examined for number and total weight of seizures from March 2019 through September 2020 using Joinpoint regression. RESULTS:Significant decreases in seizures involving marijuana (β = -0.03, P = 0.005) and methamphetamine (β = -0.02, P = 0.026) were detected through April 2020, and then seizures of marijuana (β = 0.10, P = 0.028) and methamphetamine (β = 0.11, P = 0.010) significantly increased through September 2020. The number of seizures involving marijuana and methamphetamine peaked in August 2020, exceeding the highest pre-COVID-19 number of seizures. Fentanyl seizures increased overall (β = 0.05, P < .001), but did not significantly drop during the start of COVID-19, and significant changes were not detected for cocaine or heroin. We also detected a significant increase in weight of marijuana seized from April through September 2020 (β = 0.40, P = .001). The weight of marijuana seized in August 2020 exceeded the highest pre-COVID-19 weight. CONCLUSION/CONCLUSIONS:The COVID-19 pandemic was associated with an immediate decrease in marijuana and methamphetamine seizures, and then increases throughout 2020 with some months exceeding the number (and weights) of seizures from the previous year. More research is warranted to determine the extent to which these seizures reflect changes in drug use.

BACKGROUND:Tumor mutation burden (TMB) has been associated with melanoma immunotherapy (IT) outcomes, including survival. We explored whether combining TMB with immunogenomic signatures recently identified by The Cancer Genome Atlas (TCGA) can refine melanoma prognostic models of overall survival (OS) in patients not treated by IT. METHODS:Cox proportional-hazards (Cox PH) analysis was performed on 278 metastatic melanomas from TCGA not treated by IT. In a discovery and two validation cohorts Cox PH models assessed the interaction between TMB and 53 melanoma immunogenomic features to refine prediction of melanoma OS. RESULTS:Interferon-γ response (IFNγRes) and macrophage regulation gene signatures (MacReg) combined with TMB significantly associated with OS (p = 8.80E-14). We observed that patients with high TMB, high IFNγRes and high MacReg had significantly better OS compared to high TMB, low IFNγRes and low MacReg (HR = 2.8, p = 3.55E-08). This association was not observed in low TMB patients. CONCLUSIONS:We report a model combining TMB and tumor immune features that significantly improves prediction of melanoma OS, independent of IT. Our analysis revealed that patients with high TMB, high levels of IFNγRes and MacReg had significantly more favorable OS compared to high TMB patients with low IFNγRes and low MacReg. These findings may substantially improve current melanoma prognostic models.
