https://www.selleckchem.com/products/terephthalic-acid.html Perforated colonic diverticulitis usually requires surgical resection, with significant morbidity. Short-term results from randomized clinical trials have indicated that laparoscopic lavage is a feasible alternative to resection. However, it appears that no long-term results are available. To compare long-term (5-year) outcomes of laparoscopic peritoneal lavage and primary resection as treatments of perforated purulent diverticulitis. This international multicenter randomized clinical trial was conducted in 21 hospitals in Sweden and Norway, which enrolled patients between February 2010 and June 2014. Long-term follow-up was conducted between March 2018 and November 2019. Patients with symptoms of left-sided acute perforated diverticulitis, indicating urgent surgical need and computed tomography-verified free air, were eligible. Those available for trial intervention (Hinchey stages <IV) were included in the long-term follow-up. Patients were assigned to undergo laparoscopic peritoneal lavage or couraged. ClinicalTrials.gov Identifier NCT01047462. ClinicalTrials.gov Identifier NCT01047462. Skeletal muscle depletion is common in old adults and individuals with chronic comorbidities, who have an increased risk of developing severe coronavirus disease 2019 (COVID-19), which is defined by hypoxia requiring supplemental oxygen. This study aimed to determine the association between skeletal muscle depletion and clinical outcomes in patients with severe COVID-19. One hundred and sixteen patients with severe COVID-19 who underwent chest computed tomography scan on admission were included in this multicenter, retrospective study. Paraspinal muscle index (PMI) and radiodensity (PMD) were measured using computed tomography images. The primary composite outcome was the occurrence of critical illness (respiratory failure requiring mechanical ventilation, shock, or intensive care unit admission) or death, and the seconda
