Observational Study
Carotid Ultrasound in Assessing Fluid Responsiveness in Patients with Hypotension and Suspected Sepsis.
We sought to assess whether ultrasound (US) measurements of carotid flow time (CFTc) and carotid blood flow (CBF) predict fluid responsiveness in patients with suspected sepsis. ⋯ In patients with suspected sepsis, a fluid challenge resulted in a significant change in CFTc, but not CBF. Neither absolute measurement nor delta measurements with fluid challenge predicted clinical outcomes.

Comparative Study
Comparison of the Protective Effect of Different Mild Therapeutic Hypothermia Temperatures on Intestinal Injury after Cardiopulmonary Resuscitation in Rats.
Therapeutic temperature management (TTM) is the standard treatment protocol for unconscious post-resuscitation patients. However, there is still controversy about the ideal targeted temperature of mild hypothermia therapy. Additionally, studies about protective therapy for post-resuscitation intestinal injury are very limited. Therefore, this study was performed to explore: whether mild hypothermia therapy can exert a protective effect on post-resuscitation intestinal injury; the protective effect of different targeted temperatures on post-resuscitation intestinal injury and the ideal targeted temperature; the potential protective mechanism of mild hypothermia therapy for post-resuscitation intestinal injury. ⋯ Mild hypothermia therapy can improve post-resuscitation intestinal injury, and a targeted temperature of 33°C may confer more benefit for mitigation of intestinal injury as compared with a targeted temperature of 35°C.

Multicenter Study Observational Study
Does Chloride Intake at The Early Phase of Septic Shock Resuscitation Impact on Renal Outcome?
Fluid administration is one of the first lines of treatment for hemodynamic management of sepsis and septic shock. Studies investigating the effects of chloride-rich fluids including normal saline on renal function report controversial findings. ⋯ At the early stage of resuscitation of critically ill patients with septic shock, administration of "high-dose" of chloride (> 18 g/48 h) was not associated with renal prognosis.

Rhabdomyolysis (RM) has been associated with many viral infectious diseases, and associated with poor outcomes. We aim to evaluate the clinical features and outcomes of RM in patients with coronavirus disease 2019 (COVID-19). ⋯ RM might be an important contributing factor to adverse outcomes in COVID-19 patients. The early detection and effective intervention of RM may help reduce mortality among COVID-19 patients.

Randomized Controlled Trial
Brief High Oxygen Concentration Induces Oxidative Stress in Leukocytes and Platelets - A Randomised Cross-Over Pilot Study in Healthy Male Volunteers.
Supplemental oxygen is administered routinely in the clinical setting to relieve or prevent tissue hypoxia, but excessive exposure may induce oxidative damage or disrupt essential homeostatic functions. It is speculated that oxidative stress in leukocytes and platelets may contribute to vascular diseases by promoting inflammation and cell aggregation. ⋯ Clinically relevant oxygen exposure induces oxidative stress in leukocytes and platelets, which may influence the immune and clotting functions of these cells.
