Practice Guideline
Perioperative Management of Antithrombotic Therapy: An American College of Chest Physicians Clinical Practice Guideline.
The American College of Chest Physicians Clinical Practice Guideline on the Perioperative Management of Antithrombotic Therapy addresses 43 Patients-Interventions-Comparators-Outcomes (PICO) questions related to the perioperative management of patients who are receiving long-term oral anticoagulant or antiplatelet therapy and require an elective surgery/procedure. This guideline is separated into four broad categories, encompassing the management of patients who are receiving: (1) a vitamin K antagonist (VKA), mainly warfarin; (2) if receiving a VKA, the use of perioperative heparin bridging, typically with a low-molecular-weight heparin; (3) a direct oral anticoagulant (DOAC); and (4) an antiplatelet drug. ⋯ Substantial new evidence has emerged since the 2012 iteration of these guidelines, especially to inform best practices for the perioperative management of patients who are receiving a VKA and may require heparin bridging, for the perioperative management of patients who are receiving a DOAC, and for patients who are receiving one or more antiplatelet drugs. Despite this new knowledge, uncertainty remains as to best practices for the majority of perioperative management questions.

Indeterminate randomized controlled trials (RCTs) in ARDS may arise from sample size misspecification, leading to abandonment of efficacious therapies. ⋯ Reporting of sample size estimations was inconsistent in ARDS RCTs, and misspecification of CER and ATE was common. Prognostic enrichment strategies in ARDS RCTs based on all-cause mortality are unlikely to be successful. Bayesian methods can be used to prioritize interventions for future effectiveness RCTs.

Professionalism in health care occurs in environments that present complex ethical dilemmas that demand ideal individual and team performance. Clinicians who behave unprofessionally toward patients and family members create a disproportionate share of risk for adverse patient outcomes and malpractice claims. However, when made aware, the vast majority will self-regulate. ⋯ Alternatively, the clinician could ensure that the story is reported, reviewed, and shared through the organization's professional accountability program. Professional accountability programs must be supported by appropriate infrastructure elements. Sharing the observation helps to address the concerns and fears of patients and family members, offers a colleague the chance to reflect and reduce the likelihood of future unprofessional behavior, and seeks to fulfill one's individual responsibility to support colleagues as professionals, while striking the right balance of dignity, respect, and pursuit of trust for all key stakeholders.

Randomized Controlled Trial
Neurovascular Dysregulation and Acute Exercise Intolerance in ME/CFS: A Randomized, Placebo-Controlled Trial of Pyridostigmine.
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is characterized by intractable fatigue, postexertional malaise, and orthostatic intolerance, but its pathophysiology is poorly understood. Pharmacologic cholinergic stimulation was used to test the hypothesis that neurovascular dysregulation underlies exercise intolerance in ME/CFS. ⋯ gov.

Observational Study
Clinical characteristics, treatment persistence and outcomes among patients with COPD treated with single- or multiple-inhaler triple therapy: a retrospective analysis in Spain.
COPD is a leading cause of death and disability. COPD therapy goals include reducing exacerbations and improving symptom control. Single-inhaler triple therapy (SITT) or multiple-inhaler triple therapy (MITT) is indicated for patients with frequent exacerbations despite bronchodilator therapy. No available evidence compares SITT vs MITT in Spain in terms of treatment persistence, exacerbations, and other outcomes. ⋯ Patients initiating SITT had a clinically relevant improvement in persistence leading to reductions in mortality, incidence of exacerbations, and health care resource use with consequent mean cost savings.
