The emerging roles of next-generation metabolomics in critical care nutrition.

Critical illness leads to millions of deaths worldwide each year, with a significant surge due to the COVID-19 pandemic. Patients with critical illness are frequently associated with systemic metabolic disorders and malnutrition. The idea of intervention for critically ill patients through enteral and parenteral nutrition has been paid more and more attention gradually.

Association between urinary per- and poly-fluoroalkyl substances and COVID-19 susceptibility.

Background And Objective: The growing impact of the COVID-19 pandemic has heightened the urgency of identifying individuals most at risk of infection. Per- and poly-fluoroalkyl substances (PFASs) are manufactured fluorinated chemicals widely used in many industrial and household products. The objective of this case-control study was to assess the association between PFASs exposure and COVID-19 susceptibility and to elucidate the metabolic dysregulation associated with PFASs exposure in COVID-19 patients.

Transurethral electric coagulation combined with retroperitoneal laparoscopic nephroureterectomy for upper urinary urothelial carcinoma.

Retroperitoneal laparoscopic nephroureterectomy (LNU) combined with transurethral electric resection of ipsilateral bladder cuff is widely accepted to treat the upper urinary tract urothelial carcinoma (UUT-UC). To reduce the local recurrence rate, we improved the procedure from electric resection to electric coagulation. From May 2008 to July 2012, of all the 156 retroperitoneal LNU patients, 76 cases (test group) were performed with LNU combined with electric coagulation, and 80 cases (control group) were with electric resection.
