In Peru, as in the Americas overall, men who have sex with men (MSM) are disproportionately affected by HIV. Most research focuses on practices between cisgender men, whereas many MSM report male and female partners, cisgender, transgender, or both.

Data for these analyses were from a treatment-as-prevention study in Lima (the Sabes study). We compared demographics and behaviors of MSM who reported cisgender women partners in the past 3 months (MSMW) and MSM who reported both cisgender and transgender women partners (MSMW-T) to MSM who reported only male partners (MSMO). Alpelisib inhibitor We calculated HIV incidence in each group during 2-year follow-up.

Compared with MSMO, MSMW and MSMW-T more often self-identify as heterosexual or bisexual and report insertive sex practices. MSMW reported condomless sex with cisgender women vaginal (72%), anal sex (18%). One-third of MSMW reported condomless receptive anal sex with men in the past 3 months, with 24% of MSMW overall who reported both condomless receptive sex with men and condomless insertive vaginal or anal sex with cisgender women. Of these, 17% were HIV infected. HIV incidence did not differ significantly between groups.

Most MSMW and MSMW-T report bisexual or heterosexual orientation and prefer insertive sex. MSMW and MSMW-T (47% and 29%, respectively) engage in receptive anal intercourse. In both groups, the majority who engaged in condomless receptive sex with men (76% MSMW, 85% MSMW-T) also engaged in condomless vaginal and/or anal sex with women, indicating need for intervention.

Male sex workers (MSW) are disproportionately affected by HIV/AIDS, with an estimated HIV prevalence in the United States of 19.3%. Existing research suggests that MSW are also at risk of adverse psychosocial problems. Cross-sectional studies of MSW have suggested that co-occurring epidemics or a "syndemic" of psychosocial problems may increase vulnerability to HIV acquisition/transmission by elevated sexual risk. To the best of our knowledge, there are no published studies examining this relationship longitudinally among MSW. This study examined how a syndemic of 6 psychosocial problems result in additive risk for condomless anal sex (CAS) with male clients among a multicity, longitudinal cohort of MSW.

Community-based organization and health center in 2 Northeastern US cities.

Between 2015 and 2017, 100 MSW from Boston, MA and Providence, RI completed behavioral/psychosocial surveys at baseline, 6 months, and 12months. Generalized estimating equation modeling was used to examine the prospective relatihosocial problems (adjusted odds ratio = 5.18, 95% CI 1.61 to 16.62).

Internet escorts and street-based MSW are likely to experience psychosocial problems and engaging in HIV sexual risk with male clients. The accumulation of psychosocial problems additively predicted CAS with male clients in a prospective cohort of MSW. The specification of psychosocial problems presents distinct treatment targets for HIV prevention among MSW in the United States.

Heart failure with reduced ejection fraction (HFrEF) and chronic obstructive pulmonary disease (COPD) are relatively common conditions with similar symptoms of exercise intolerance and dyspnea. The aim of this study was to compare exercise capacity, ventilatory response, and breathing pattern in patient groups with either advanced HFrEF or COPD before and after exercise training.

An observational study was conducted with parallel groups of 25 HFrEF and 25 COPD patients who took part in 6 wk of inpatient rehabilitation with exercise training. All patients underwent cardiopulmonary exercise tests at the start and end of the training, with resting arterial blood gas measurements.

The average peak oxygen uptake (V˙o2) was low at the start of the study but increased significantly after training in both groups, or by 2.2 ± 2.1 mL/kg/min in HFrEF patients and 1.2 ± 2.2 mL/kg/min in COPD patients. At ISO-V˙o2 (ie, same level of V˙o2 in pre- and post-exercise tests), carbon dioxide production (V˙co2) decreased alized outcome measures in treatment studies.

Heart disease in children and adolescents is common, approaching 1.0% of the population. In those patients with complex physiology and severe cardiac dysfunction, the inability to participate in physical activity results in significant obstacles to normal acts of daily living and significantly diminished quality of life. Attempts to study the practicality and benefits of cardiopulmonary rehabilitation (CR) programs in this population have been hampered by the heterogeneity of lesions, lack of facilities, and trained personnel to supervise these types of programs. Although there are numerous articles on CR in children with cardiac disease, all suffer from the same basic problems of small sample size, short duration of study, and heterogeneous study populations.

The purpose of this review was to first evaluate the current rehabilitation literature on both congenital cardiac defects and acquired abnormalities-in this latter group placing a significant emphasis on cardiomyopathies, as well as the special popufor complex heart disease and impaired myocardial function. Current research holds the promise for the development of programs that are practical, scalable, and can be implemented in most clinical sites within the foreseeable future.

Pseudomonas aeruginosa is one of the most feared nosocomial pathogens. Treatment of P. aeruginosa infections is challenging because of the limited choices of antibiotics and the emergent resistance of the pathogen. The present review aims at addressing the management of P. aeruginosa infections and highlighting the novel antibiotics that show a future promising role.

Novel fluoroquinolones have been recently introduced and show favorable activity. New combinations of β-lactams/β-lactamase inhibitors have been studied in various indications of infections because of P. aeruginosa. Cefiderocol, a new cephalosporin, shows very promising results against P. aeruginosa. Currently, combination therapy is only recommended in limited scenarios. Extended-infusion of β-lactams exhibit clinical benefit. Bacteriophage therapy is a growing field of interest and may have an impactful effect on the treatment of resistant P. aeruginosa.

Factors that guide clinical decisions for empiric and directed P. aeruginosa therapy include the epidemiology, the patient's risk factors, the site of infection, and the available treatment options. Conventional antipseudomonal antibiotics have been used successfully for a long time, but the increase in worldwide resistance necessitates the need for newer agents. Antimicrobial stewardship is essential to preserve the new drugs and prevent future development of resistance.

Although there is increasing recognition of the link between antibiotic overuse and antimicrobial resistance, clinician prescribing is often unnecessarily long and motivated by fear of clinical relapse. High-quality evidence supporting shorter treatment durations is needed to give clinicians confidence to change prescribing habits. Here we summarize recent randomized controlled trials investigating antibiotic short courses for common infections in adult patients.

Randomized trials in the last five years have demonstrated noninferiority of short-course therapy for a range of conditions including community acquired pneumonia, intraabdominal sepsis, gram-negative bacteraemia and vertebral osteomyelitis.

Treatment durations for many common infections have been based on expert opinion rather than randomized trials. There is now evidence to support shorter courses of antibiotic therapy for many conditions.

The gut microbiome presents a novel source of diagnostic and therapeutic potential to modify post allogeneic stem cell transplant complications. There is an explosion of interest in microbiome research, mostly in the form of single-centre prospective time-series cohorts utilizing a variety of sampling frequencies and metagenomic technologies to sequence the microbiome. The purpose of this review is to summarize important recent publications and contextualize them within what has already been described in this rapidly growing field.

Results from observational human cohort and animal transplant models add to the growing body of evidence that the microbiome modulates the immunopathogenesis of posttransplant complications. This is particularly the case for recipients of grafts replete with T cells where the evidence that acute graft-versus-host disease is mediated by anaerobic commensal-associated short-chain fatty acids, which interact with mucosa-associated (CD4FOXP3) T-regulatory cells.

Future human research into the role of the microbiome in allogeneic stem transplant should incorporate rigorous and considered experimental design in addition to next-generation sequencing technology to better portray microbiome functional potential and active gene expression. In combination with host immune phenotyping, which would facilitate a robust understanding of the host--microbiome interaction that is required before meaningful translation into clinical diagnostics and therapeutics can be expected.

Urinary tract infection (UTI) is the most common infection in kidney transplant recipients (KTRs). Several elements increase the risk of UTI and/or modify its clinical presentation among KTRs (e.g. immunosuppressive therapy, kidney allograft denervation, and use of urinary catheters). Also, KTRs may have UTIs because of difficult-to-identify and/or difficult-to-treat organisms. We provide an overview of the current knowledge regarding bacterial UTIs in KTRs, with a focus on recent findings.

There is accumulating evidence from clinical trials that screening for and treating asymptomatic bacteriuria is not beneficial in most KTRs (i.e. those who are ≥1-2 months posttransplant and do not have a urinary catheter). These patients have a point-prevalence of asymptomatic bacteriuria of only 3% and treating asymptomatic bacteriuria probably does not improve their outcomes. There is no clinical trial evidence to guide the management of symptomatic UTI in KTRs. Several important clinical questions remain unanswered, especially regarding the management of posttransplant pyelonephritis and the prevention of UTI in KTRs.
