Introduction Discontinuations of HIV preexposure prophylaxis (Pr EP ) by at‐risk individuals could decrease the effectiveness of Pr EP . Our objective was to characterize patterns of, reasons for, and clinical outcomes associated with Pr EP discontinuations in primary care. Methods We conducted medical chart reviews for patients prescribed Pr EP during 2011 to 2014 at a Boston community health centre specializing in healthcare for sexual and gender minorities. Patients were followed through 2015. We characterized patients’ sociodemographics, relationship status, behavioural health conditions, patterns of and reasons for Pr EP discontinuations, and HIV seroconversions. Cox proportional hazards models were used to assess patient factors associated with Pr EP discontinuations. Results Of the 663 patients prescribed Pr EP , the median age was 33 years, 96% were men who have sex with men ( MSM ) and 73% were non‐Hispanic white; 40% were in committed relationships and 15% had HIV ‐infected partners. Patients either used Pr EP continuously (60%), had 1 or more discontinuations (36%), or did not initiate Pr EP (4%). Discontinuations were most often due to a decrease in HIV risk perception (33%), non‐adherence to care plans (16%), or insurance barriers (12%). Of the 7 (1.1%) Pr EP patients diagnosed with HIV , 1 was HIV ‐infected at baseline, 2 seroconverted while using Pr EP , and 4 seroconverted after discontinuations. In a multivariable model adjusted for race/ethnicity, relationship status, substance use disorders, and insurance status, those who were less than 30 years old ( aHR 2.0, 95% CI 1.4 to 2.9 for ages 18 to 24, aHR 2.2, 95% CI 1.6 to 3.1 for ages 25 to 29, vs. ages 30 to 39 years), who identified as transgender women ( aHR 2.0, 95% CI 1.2 to 3.4, vs. cisgender men), and who had mental health disorders ( aHR 1.2, 95% CI 1.1 to 1.4 for each additional disorder) were more likely to have discontinuations. Conclusions Discontinuations of Pr EP use among this American sample of predominately MSM were common, particularly among patients who were younger, identified as transgender women, or had behavioural health issues.

Clinical studies have demonstrated that use of tenofovir disoproxil fumarate with or without emtricitabine as antiretroviral preexposure prophylaxis (PrEP) can decrease the risk of HIV acquisition when medication adherence is high. However, the potential for PrEP to promote antiretroviral resistance remains an important public health consideration. We performed a search of the medical literature to identify studies that address HIV drug resistance during PrEP use. In this review, we summarize findings about emergent drug resistance during clinical trials of PrEP, case reports of seroconversions in adherent PrEP patients, and animal studies of PrEP effectiveness against drug resistant viral strains. We also discuss the potential utility of novel PrEP formulations for protection against drug resistant HIV, the impact of drug resistance on HIV treatment options, and mathematical models that estimate the potential contribution of PrEP to population-level drug resistance. Evidence suggests that selection for HIV drug resistance with PrEP use is infrequent and most likely to occur when PrEP is used during undiagnosed acute HIV infection. Breakthrough infections during PrEP use with high adherence are possible, but appear to be rare. The prevalence of drug resistant HIV strains needs to be monitored as PrEP is scaled-up. However, the benefit of decreased HIV incidence with wider PrEP use is likely to outweigh the risk of harms from possible increases in the prevalence of HIV drug resistance.

Context. Immune checkpoint inhibitors (ICIs) are increasingly used to treat a variety of cancers, but comparatively little is known about patient-reported outcomes (PROs) and health-related quality of life (HRQoL) among patients receiving these novel therapies.Objectives. We performed a systematic review to examine PROs and HRQoL among cancer patients receiving ICIs as compared to other anticancer therapies.Methods. We systematically searched PubMed, CINAHL, Embase, Web of Science, and Scopus, using search terms representing ICIs, PROs, and HRQoL on August 10, 2018. Eligible articles were required to involve cancer patients treated with ICIs and to report PROs and/or HRQoL data.Results. We screened 1453 references and included 15 publications representing 15 randomized controlled trials in our analysis. Studies included several cancer types (melanoma, lung cancer, genitourinary cancer, and head/neck cancer), used four different ICIs (nivolumab, pembrolizumab, atezolizumab, and ipilimumab), and compared ICIs to a wide range of therapies (chemotherapy, targeted therapies, other immunotherapy strategies, and placebo). Studies used a total of seven different PROs to measure HRQOL, most commonly the European Organisation for the Research and Treatment of Cancer core quality of life questionnaire (EORTC QLQ-C30) (n ¼ 12, 80%). PRO data were reported in a variety of formats and at a variety of time points throughout treatment, which made direct comparison challenging. Some trials (n ¼ 11, 73%) reported PROs on specific symptoms. In general, patients receiving ICIs had similar-to-improved HRQoL and experiences when compared to other therapies.Conclusion. Despite the broad clinical trials experience of ICI therapies across cancer types, relatively few randomized studies reported PROs and patient HRQoL data. Available data suggest that ICIs are well tolerated in terms of HRQoL compared to other anticancer therapies although the conclusions are limited by the heterogeneity of trial designs and outcomes. Currently used instruments may fail to capture important symptomatology unique to ICIs, underscoring a need for PROs designed specifically for ICIs.

Rates of non-adherence varied by information source. Better self-reported physical functioning was the strongest predictor of adherence. Parental involvement in adherence was associated with worse PedsQL School Functioning and lower MS Self-Efficacy-measured confidence in controlling MS.

Context. Although the literature on transitions from hospital to the community is extensive, little is known about this experience within the context of palliative care (PC).Objective. We conducted a systematic review to investigate the impact of receiving palliative care in hospital on the transition from hospital to the community.Methods. We systematically searched MEDLINE, Embase, ProQuest, and CINAHL from 1995 until April 10, 2018, and extracted relevant references. Eligible articles were published in English, included adult patients receiving PC as inpatients, and explored transitions from hospital to the community.Results. A total of 1514 studies were identified and eight met inclusion criteria. Studies were published recently (>2012; n ¼ 7, 88%). Specialist PC interventions were delivered by multidisciplinary care teams as part of inpatient PC triggers, discharge planning programs, and transitional care programs. Common outcomes reported with significant findings consisted of length of stay (n ¼ 5), discharge support (n ¼ 5), and hospital readmissions (n ¼ 6) for those who received inpatient PC. Most studies were at high risk of bias.Conclusion. Heterogeneity of study designs, outcomes, findings, and poor methodological quality renders it challenging to draw conclusions regarding PC's impact on the transition from hospital to home. Further research should use standardized outcomes with randomized controlled trial and/or propensity matched cohort designs.

IntroductionExtended half-life factor products have reduced annualized bleeding rates in hemophilia patients. The impact of extended half-life versus conventional factor products on hemophilia caregiver burden has not been investigated. This study aimed to evaluate caregiver burden in extended half-life versus conventional factor products for hemophilia A and B.MethodsThis cross-sectional web-based study of caregivers of people with hemophilia A or B was recruited from a panel research company and by word of mouth. Participants completed the Hemophilia Caregiver Impact measure, the PedsQL Family Impact Module (PedsQL), and the Work Productivity and Activity Impairment Questionnaire (WPAI). We also collected demographic, insurance coverage, and medical information related to the hemophilia patient(s). Burden differences were assessed using linear regression and matched cohort analyses.ResultsThe sample (n = 448) included 49 people who were caring for people on extended half-life factor products. Worse caregiver burden was associated with more infusions per week and more bleeds in the past 6 months. Regression analyses suggested that caring for someone who is on a extended half-life factor product is associated with lower emotional impact (β = − 0.11, p < 0.05, Adjusted R2 = 0.06), and shows a trend association with lower practical impact (β = − 0.09, p < 0.10, Adjusted R2 = 0.05). The matched cohort analysis also revealed that people on extended half-life factor product had lower Emotional Impact and Practical Impact scores (t = − 2.95 and − 2.94, respectively, p < 0.05 in both cases). No differences were detected on the PedsQL or the WPAI.ConclusionThe reduced required frequency of factor product infusions of extended half-life factor products appears to reduce the emotional distress and practical burden of caregiving. Future work should evaluate the longitudinal impact.

PrEP use was associated with receipt of influenza vaccination, tobacco and depression screening, and glucose but not hemoglobin A1c testing. Among PrEP users receiving routine care, the benefits of PrEP may extend to behavioral health, mental health, and prevention and treatment of other infectious and chronic diseases.
