Randomized Controlled TrialIV Vitamin C in Adults With Sepsis: A Bayesian Reanalysis of a Randomized Controlled Trial.
The Lessening Organ Dysfunction with Vitamin C trial showed a harmful effect of vitamin C on 28-day death or persistent organ dysfunction. To maximize interpretation, we present a post hoc Bayesian reanalysis. ⋯ The use of vitamin C in adult patients with proven or suspected infection and vasopressor support is associated with high probability of harm.

A Comparison of Long-Term Outcomes in Patients Managed With Venovenous Extracorporeal Membrane Oxygenation in the First and Second Waves of the COVID-19 Pandemic in the United Kingdom.
Early studies of venovenous extracorporeal membrane oxygenation (ECMO) in COVID-19 have revealed similar outcomes to historical cohorts. Changes in the disease and treatments have led to differences in the patients supported on venovenous ECMO in the first and second waves. We aimed to compare these two groups in both the acute and follow-up phase. ⋯ Most patients with COVID-19 supported on ECMO in both waves survived in the short and longer term. At follow-up patients had similar lung function and QOL across the two waves. This suggests that ECMO has an ongoing role in the management of a carefully selected group of patients with COVID-19.

Diabetes mellitus is the most common metabolic disease with >500 million people affected worldwide and currently 8,7 million in Germany. About 90% of diabetes cases are due to type 2 diabetes mellitus (T2D). This form of diabetes is characterized by an increased release of proinflammatory adipokines, endothelial dysfunction and hyperglycemia, among others. ⋯ People with diabetes are therefore generally considered a high-risk cardiovascular group and require special attention in the diagnosis and treatment of cardiovascular disease. Contributing factors to reduce high cardiovascular risk include a healthy lifestyle, normalization of blood pressure, optimization of blood lipid levels, and specific diabetes therapy tailored to cardiovascular risk. This review addresses the specific treatment options for reducing cardiovascular risk in patients with diabetes mellitus.

The administration of epinephrine after severe refractory hypotension, shock, or cardiac arrest restores systemic blood flow and major vessel perfusion but may worsen cerebral microvascular perfusion and oxygen delivery through vasoconstriction. The authors hypothesized that epinephrine induces significant microvascular constriction in the brain, with increased severity after repetitive dosing and in the aged brain, eventually leading to tissue hypoxia. ⋯ Intravenous application of epinephrine induced marked cerebral microvascular constriction, intravascular hemoglobin desaturation, and paradoxically, an increase in brain tissue oxygen levels, likely due to reduced transit time heterogeneity.

The parasympathetic system and its main neurotransmitter, acetylcholine, contributes to homeostasis of inflammation. Cholinergic dysregulation is thought to contribute to the pathogenesis of inflammatory rheumatic diseases. Cholinesterase activity in patients with psoriatic arthritis (PsA) has not been investigated. ⋯ We demonstrated similar cholinesterase activity in patients with psoriatic arthritis and controls, highlighting a potential effect of biologic treatment on cholinergic activity in patients with PsA.
