Objective: To review literature on the use of direct-acting oral anticoagulants (DOACs) in patients with high body weight (BW) and/or high body mass index (BMI) and to make recommendations regarding use in this patient population. Data Sources: A search using PubMed was conducted (inception to April 13, 2020) using the term DOAC AND the terms obesity OR body weight. A separate search was also conducted with individual DOACs (dabigatran, apixaban, rivaroxaban, edoxaban) and the aforementioned terms. Study Selection and Data Extraction: Studies included examined the effect of BW and/or BMI on DOAC pharmacokinetics, efficacy, or safety. Included studies had DOAC indications of prevention of stroke in nonvalvular atrial fibrillation, or treatment or long-term prevention of venous thromboembolism. Data Synthesis: The efficacy and safety of DOACs in patients with high BW/BMI has not yet been elucidated by randomized trials; however, 2016 international guidelines suggest avoiding their use in patients with a BW >120 kg or BMI >40 kg/m2. Since 2016, several studies have been published examining use of DOACs in this patient population. Relevance to Patient Care and Clinical Practice: This review thoroughly discusses the literature on DOACs in patients with a BW >120 kg or BMI >40 kg/m2 pre-2016 and post-2016 guidelines. Conclusions: Evidence indicates that each DOAC may have differences in outcomes when used in patients with a high BW/BMI. Currently, low-quality data are available that support avoiding dabigatran and considering apixaban or rivaroxaban; lack of sufficient data preclude a recommendation for edoxaban use in this patient population.

STRs have significantly advanced HIV management by minimizing pill burden and improving patient compliance. It is important to consider the nuances of each STR in regard to renal and hepatic function, drug interactions, and tolerability, to ensure safe and effective use.

Background: Data on the effectiveness of definitive oral (PO) antibiotics for BSIs in preparation for discharge from hospital are lacking, particularly for Gram-positive bacterial BSIs (GP-BSI). The objective of this study was to determine rates of treatment failure based on bioavailability of PO antimicrobial agents used for GP-BSI. Methods: This was a single-center, retrospective cohort study of adult inpatients admitted to an academic medical center over a three-year period. Patients with a non-staphylococcal GP-BSI who received intravenous antibiotics and were then switched to PO antibiotics for at least a third of their treatment course were included. The cohort was stratified into high (⩾90%) and low (<90%) bioavailability groups. The primary endpoint was the proportion of patients experiencing clinical failure in each group. Secondary endpoints included clinical failure stratified by antibiotic group, bactericidal versus bacteriostatic PO agents, and organism. Results: A total of 103 patients met criteria for inclusion, which failed to reach the a priori power calculation. Of the patients included, 26 received high bioavailability agents and 77 received low bioavailability agents. Infections originated largely from a pulmonary source (30%) and were caused primarily by streptococcal species (75%). Treatment failure rates were 19.2% in the high bioavailability group and 23.4% in the low bioavailability group ( p = 0.66). Clinical failure stratified by subgroups also did not yield statistically significant differences. Conclusions: Clinical failure rates were similar among patients definitively treated with high or low bioavailability agents for GP-BSI, though the study was underpowered to detect such a difference.

A retrospective study in one institution revealed that the first measured voriconazole concentration was within the target range in 53% of patients and that dosage was modified in only 51% of patients whose concentration was outside of that range. The majority of patients with above-target concentrations had an adverse effect, and this result was particularly common in patients with a body mass index of ≥35 kg/m(2).

The risk-benefit ratio of fluoxetine in underweight and weight-restored patients with AN is undefined by clinical trials; therefore, clinical experience must be applied for its use in this patient population.

STRs and agents in the pipeline continue to simplify ART regimens, increase medication adherence, and minimize toxicities.

Inadequately treated depression led to increased health-care resource utilization. Patients with adequately treated depression had similar outcomes as those with no depression. Use of sleep aids early post-LTX may be a surrogate indicator of inadequately treated depression.
