Corticosteroids have beneficial effects in improving outcomes in hospitalized patients with severe COVID-19 by suppressing excessive immune responses. However, the effect of corticosteroids on the humoral and T-cell responses of survivors of COVID-19 1 year after infection remains uncertain, as it relates to the extent of immediate, antigen-specific defense provided by protective memory. ⋯ Based on our findings, short-term and low-dose corticosteroid therapy during hospitalization does not appear to have a significant effect on long-term humoral kinetics or the magnitude and rate of memory T-cell responses to SARS-CoV-2 antigens. However, the potential harmful effects of long-term and high-dose corticosteroid use on memory immune responses require further investigation.

Enrollment into critical care clinical trials is often hampered by the need to rely on surrogate decision-makers. To identify potential interventions facilitating enrollment into critical care clinical trials, a better understanding of surrogate decision-making for critical care clinical trial enrollment is needed. ⋯ This study confirms and extends previous findings that health system trust, study risks and benefits, altruism, knowledge generation, interference with clinical care, and placebos are key concerns and barriers for surrogate decision-makers to enroll patients in critical care trials. Future studies are needed to evaluate if charitable giving on the patient's behalf and public recognition are effective strategies to promote enrollment into critical care trials.

Use of Intravenous Albumin: A Guideline from the International Collaboration for Transfusion Medicine Guidelines.
Albumin is used commonly across a wide range of clinical settings to improve hemodynamics, to facilitate fluid removal, and to manage complications of cirrhosis. The International Collaboration for Transfusion Medicine Guidelines developed guidelines for the use of albumin in patients requiring critical care, undergoing cardiovascular surgery, undergoing kidney replacement therapy, or experiencing complications of cirrhosis. ⋯ Currently, few evidence-based indications support the routine use of albumin in clinical practice to improve patient outcomes. These guidelines provide clinicians with actionable recommendations on the use of albumin.

An 81-year-old man who currently smokes with a 30-pack-year history presented with involuntary rhythmic motion of his right hand that had started insidiously and progressively worsened over the past 5 months. His medical history included hypertension and dyslipidemia. He did not have a prior history of pulmonary disease and currently denied any shortness of breath or cough. He did however report an unintentional weigh loss of 5 kg within the past few months.

A 41-year-old man who currently smokes with previous sporadic use of cocaine and cannabinoids was admitted at the hospital suffering from hemoptysis which had developed 4 days before. The patient was on anticoagulant therapy with rivaroxaban due to paroxysmal atrial fibrillation diagnosed in 2018, for which he had undergone pulmonary vein electrical isolation by radiofrequency and ablation of cavotricuspid isthmus in January 2019. ⋯ In February 2021, a new attempt at ablation was performed by electrical isolation of the left atrial posterior wall. The latest cardiologic checkup documented an echocardiographic framework of mild left atrial dilatation and normal-sized right ventricle with longitudinal shortening index at the lower limits, and a recurrence of asymptomatic atrial fibrillation at Holter ECG (March 2022).
