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.

In people with COPD, pulmonary gas-exchange efficiency may be impaired because of abnormal alveolar ventilation (V˙A), capillary perfusion (Q˙c), or both. Both have been reported in early and mild stages of the disease. Such derangements often accompany significant clinical consequences such as activity-related dyspnea and exercise intolerance. ⋯ Hence, in this invited review, we first summarize how dyspnea, leading to poor exercise tolerance in COPD, may be explained by an increased venous admixture resulting from low V˙A/Q˙c, or wasted ventilation related to high V˙A/Q˙c, or both. We review the conflicting evidence supporting current treatments for gas-exchange inefficiency and exercise tolerance that act primarily on V˙A (bronchodilators, antiinflammatory medications) or Q˙c (oral and inhaled vasodilators, almitrine, and supplemental oxygen). Finally, to address the current knowledge and health care gaps, we propose two independent clinical research foci that may lead to a better understanding of the role of pulmonary gas-exchange inefficiency and activity-related dyspnea in COPD: (1) enhanced and deeper phenotyping of patients with COPD with V˙A/Q˙c abnormalities and (2) evaluation of existing and novel pharmacologic treatments to improve gas-exchange inefficiency, exertional dyspnea, and exercise tolerance across the spectrum of COPD severity.

Randomized Controlled Trial Multicenter Study
Neutralizing COVID-19 Convalescent Plasma in Adults Hospitalized with COVID-19: A Blinded Randomized Placebo-Controlled Trial.
Convalescent plasma has been one of the most common treatments for COVID-19, but most clinical trial data to date have not supported its efficacy. ⋯ gov.

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.
