Finger photopletysmography detects early acute blood loss in compensated blood donors: a pilot study.

Diagnosis of incipient acute hypovolemia is challenging as vital signs are typically normal and patients remain asymptomatic at early stages. The early identification of this entity would affect patients' outcome if physicians were able to treat it precociously. Thus, the development of a noninvasive, continuous bedside monitoring tool to detect occult hypovolemia before patients become hemodynamically unstable is clinically relevant.

A Randomized Trial of Convalescent Plasma in Covid-19 Severe Pneumonia.

Background: Convalescent plasma is frequently administered to patients with Covid-19 and has been reported, largely on the basis of observational data, to improve clinical outcomes. Minimal data are available from adequately powered randomized, controlled trials.

Methods: We randomly assigned hospitalized adult patients with severe Covid-19 pneumonia in a 2:1 ratio to receive convalescent plasma or placebo.

[Use of plasmapheresis in hypertriglyceridemic pancreatitis].

Hypertriglyceridemia is reported as cause of 1 to 4% of the episodes of acute pancreatitis. We report the case of a 42-year-old woman with a history of obesity, type 2 diabetes mellitus, hypertriglyceridemia and hypercholesterolemia, with triglycerides of 9365 mg/dl, total cholesterol of 1822 mg/dl, one month prior to the consultation. She presented at the emergency unit with a 5 day history of abdominal pain, which progressed in intensity in the last 48 hours.
