5], and 47% were non-White. Three-quarters (76%) intended to initiate PrEP within the next month. Comfort discussing sexual practices with providers was associated with PrEP use self-efficacy (b = 0.41, p = 0.008). Comfort discussing sexual practices with providers was negatively associated with anticipated barriers to PrEP uptake (b = -0.29, p = 0.006). Transportation difficulties to accessing general health care were associated with barriers to PrEP uptake (b = 0.30, p = 0.007) and barriers to PrEP adherence and retention (b = 0.57, p  less then  0.001). No health service- and provider-level characteristics were associated with intention to initiate PrEP. PrEP programs targeting MSW may benefit from interventions to foster communication between MSW and providers about sexual practices and should consider structural barriers to accessing care, including lack of access to transportation.In many low- and middle-income countries, community health workers (CHWs) support multiple aspects of HIV care, including patient education and counseling, adherence support, and re-engaging patients lost to care. In Tanzania, the Community-Based HIV Services program is a nationwide cohort of CHWs supporting HIV care engagement. We enrolled a prospective cohort study of 80 people initiating HIV care at two Tanzanian clinics and conducted baseline and 3-month follow-up assessments to examine the potential influence of CHW support and other factors on patient early self-reported medication adherence, depression, anxiety, attitudes about medication, and HIV stigma. The vast majority of participants reported maintaining strong antiretroviral therapy (ART) adherence during the study and endorsed beliefs that ART is beneficial for them. However, there was high occurrence of likely depression and anxiety disorders in the study sample. Patient contact with CHWs at the clinic was unexpectedly low; fewer than two-thirds of participants were informed about the CHW program and fewer than one-third ever met with a CHW. Among participants who met with a CHW, there was mixed feedback about the helpfulness of the program, and contact with a CHW did not improve medication adherence at 3-month follow-up. Male participants, those with likely depression, and those who lived further from the clinic were significantly more likely to experience adherence challenges. The study findings indicate that CHWs are currently underutilized to provide patient support and may not be producing observable benefits to patients in this setting, representing a missed opportunity to address patient challenges, including depression and anxiety.Migrants in countries affiliated with the Organization for Economic Co-operation and Development (OECD) have a higher risk of acquiring HIV, experience delayed HIV diagnosis, and have variable levels of engagement with HIV care and treatment when compared to native-born populations. A systematic mixed studies review was conducted to generate a multilevel understanding of the barriers and facilitators affecting HIV Care Cascade steps for migrant people living with HIV (MLWH) in OECD countries. Medline, Embase, Scopus, CINAHL, and the Cochrane Library were searched on March 25, 2020. Screening, critical appraisal, and analysis were conducted independently by two authors. We used qualitative content analysis and the five-level Socio-Ecological Model (i.e., individual, interpersonal, organizational, community, and policy) to categorize barriers and facilitators. Fifty-nine studies from 17 OECD countries were included. MLWH faced similar barriers and facilitators regardless of their host country, ethnic and geographic origins, or legal status. Most barriers and facilitators were associated with the individual and organizational levels and centered around retention in HIV care and treatment. Adapting clinical environments to better address MLWH's competing needs via multidisciplinary models would address retention issues across OECD countries.We aimed to evaluate the effect of prolonged targeted temperature management (TTM) in patients with out-of-hospital cardiac arrest (OHCA) on the levels of midregional pro-atrial natriuretic peptide (MR-proANP) and N-terminal pro b-type natriuretic peptide (NT-proBNP) and assess their potential as prognostic biomarkers. A preplanned post hoc analysis of "Targeted temperature management for 48 h vs 24 h and neurologic outcome after out-of-hospital cardiac arrest A randomized clinical trial (TTH48 trial)," where patients were randomized to TTM at 33°C ± 1°C of standard duration (24 hours) versus prolonged (48 hours). Blood samples were drawn from patients with OHCA at two Scandinavian university hospitals at admission to the ICU and at 24, 48, and 72 hours after reaching the target temperature. Primary outcome was levels of MR-proANP and NT-proBNP. Secondary outcome was cerebral performance category (CPC 1-5) at 6 months. Samples from 114 patients were analyzed. Prolonged TTM significantly decreased the levels of MR-proANP and NT-proBNP at 48 hours compared with standard 24 hours-TTM (p  less then  0.01). However, there were no significant differences at other time points. Patients with poor outcome (CPC 3-5) had a statistically significantly increased MR-proANP level at 24 hours (p  less then  0.01) and 72 hours (p  less then  0.01) compared with the good outcome group (CPC 1-2). Prognostic performance was best at 24 hours for both MR-proANP and NT-proBNP; with an AUC of 0.73 (confidence interval [95% CI] 0.63-0.83) and 0.72 (95 % CI 0.59-0.85), respectively. Prolonged TTM lowered the levels of both MR-proANP and NT-proBNP at 48 hours. MR-proANP may add prognostic information in postcardiac arrest patients.

The objective of this narrative review is to explore what is known about the activity of psychotropic medications against viruses in addition to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). PubMed was queried for "drug repurposing, antiviral activity," and for "antiviral activity" with "psychotropic drugs" and individual agents, through November 2020. Of more than 100 psychotropic agents, 37 drugs, including 27 with a history of pediatric use were identified, which had been studied in the preclinical setting and found to have activity against viruses which are human pathogens. Effects were evaluated by type of virus and by category of psychotropic agent. Activity was identified both against viruses known to cause epidemics such as SARS-CoV-2 and Ebola and against those that are the cause of rare disorders such as Human Papillomatosis Virus-related respiratory papillomatosis. Individual drugs and classes of psychotropics often had activity against multiple viruses, with promiscuity explained by shared viral or cellular targets. Safety profiles of psychotropics may be more tolerable in this context than when they are used long-term in the setting of psychiatric illness. Nonetheless, translation of in vitro results to the clinical arena has been slow. Psychotropic medications as a class deserve further study, including in clinical trials for repurposing as antiviral drugs for children and adults.In this article, we develop a new ℓ0-based sparse Poisson graphical model with applications to gene network inference from RNA-seq gene expression count data. Assuming a pair-wise Markov property, we propose to fit a separate broken adaptive ridge-regularized log-linear Poisson regression on each node to evaluate the conditional, instead of marginal, association between two genes in the presence of all other genes. The resulting sparse gene networks are generally more accurate than those generated by the ℓ1-regularized Poisson graphical model as demonstrated by our empirical studies. A real data illustration is given on a kidney renal clear cell carcinoma micro-RNA-seq data from the Cancer Genome Atlas.Although autogenous demineralized dentin matrix (auto-DDM) has shown promising clinical and histological results, it has certain limitations beyond its osteoinductivity and osteoconductivity. Therefore, the application of dentin graft material from other individuals-allogeneic DDM (allo-DDM)-has been considered an alternative to auto-DDM. However, few studies have investigated the osteoinductivity and antigenicity of allo-DDM. Herein, we reviewed all human studies related to allogeneic dentin application for the management of maxillofacial bone defects. Clinical studies have shown the osteoinductivity of allo-DDM in extraskeletal and skeletal sites, regardless of occasional antigenicity. Impact statement Although autogenous demineralized dentin matrix (auto-DDM) has shown promising clinical and histological results, it has certain limitations beyond its proven osteoinductivity and osteoconductivity. Therefore, the application of dentin graft material from other individuals-allogeneic DDM (allo-DDM)-has been considered as an alternative to auto-DDM. However, few studies have investigated the osteoinductivity and antigenicity of allo-DDM. This is the first review of all human studies related to allogeneic dentin grafts for the management of maxillofacial bone defects. Clinical studies have shown the osteoinductivity of allo-DDM in extraskeletal and skeletal sites, regardless of occasional antigenicity.Sports-related concussion (SRC) can exert serious acute and long-term consequences on brain microstructure, function, and behavioral outcomes. E6446 We aimed to quantify the alterations in white matter (WM) microstructure and global network organization, and the decrements in behavioral and cognitive outcomes from pre-season to post-concussion in youth athletes who experienced SRC. We also aimed to evaluate whether wearing a jugular compression neck collar, a device designed to mitigate brain "slosh" injury, would mitigate the pre-season to post-concussion alterations in neuroimaging, behavioral, and cognitive outcomes. A total of 488 high school football and soccer athletes (14-18 yrs) were prospectively enrolled and assigned to the non-collar group (n=237) or the collar group (n=251). The outcomes of the study were the pre-season to post-concussion neuroimaging, behavioral, and cognitive alterations. Forty-six participants (non-collar n=24; collar n=22) were diagnosed with a SRC during the season. Forty of these 46 athletes (non-collar n=20; collar n=20) completed neuroimaging assessment. Significant pre-season to post-concussion alterations in WM microstructural integrity and brain network organization were found in these athletes (corrected p less then 0.05). The alterations were significantly reduced in collar-wearing athletes compared to non-collar-wearing athletes (corrected p less then 0.05). Concussion and collar main effects were identified for some of the behavioral and cognitive outcomes, but no collar by SRC interaction effects were observed in any outcomes. In summary, young athletes exhibited significant WM microstructural and network organizational, and cognitive alterations following SRC. The use of the jugular vein compression collar showed promising evidence to reduce these alterations in high school contact sport athletes.
