Compassionate use of convalescent plasma for treatment of moderate and severe pneumonia in COVID-19 patients and association with IgG antibody levels in donated plasma.

Background: We assessed outcome of patients with moderate and severe COVID-19 following treatment with convalescent plasma (CP) and the association with IgG levels in transfused CP.

Methods: A prospective cohort study. Primary outcome was improvement at day 14 defined as alive, not on mechanical ventilation, and moderate, mild, or recovered from COVID-19.

Sepsis, septic shock, and fatal exertional heat stroke.

Exertional heat stroke (EHS) is a clinical syndrome of hyperthermia, encephalopathy, and multiorgan dysfunction that can be irreversible and fatal. While prompt recognition and immediate, aggressive total body cooling can prevent progression of the clinical syndrome, even a short delay can exacerbate the effects of hyperthermia-induced changes. EHS is linked to an inflammatory response that is akin to the systemic inflammatory response syndrome (SIRS).

Severe acidosis does not predict fatal outcomes in intensive care unit patients: a retrospective analysis.

Purpose: Severe acidosis is a potentially life-threatening acid-base imbalance. The outcome of patients with severe acidosis has only been anecdotally described. We therefore assessed the discharge rate of such patients from the intensive care unit (ICU) and survival time after the event.

Low plasma C-reactive protein level as an early diagnostic tool for heatstroke vs central nervous system-associated infection in the ED.

Purposes: Heatstroke (HS) is a life-threatening condition, manifested by systemic inflammation and multiorgan failure. Rapid recognition and treatment are life saving. We report a laboratory-oriented characterization of HS by low plasma C-reactive protein (CRP) level and propose its usefulness in distinguishing this type of hyperpyrexia from central nervous system-associated high core temperature.

Metformin-associated lactic acidosis following acute kidney injury. Efficacious treatment with continuous renal replacement therapy.

Introduction: Metformin is a biguanide anti-hyperglycaemic drug. Metformin-associated lactic acidosis may sometimes be life-threatening. Continuous renal replacement therapy has been suggested as a method for resolving this extremely dangerous metabolic state.
