Hypoalbuminemia and advanced age are risk factors for delayed gastric emptying after pancreaticoduodenectomy

Background:delayed gastric emptying (DGE) is one of the most common complications after pancreatoduodenectomy. It could be related to some baseline patient-related characteristics. This study aims to assess the predictive factors associated to DGE in the cohort of patients included in the PAUDA clinical trial. Methods:this study was a retrospective analysis based on the 80 patients included in a randomized clinical trial conducted and published by our group. A descriptive analysis and a bivariate regression model were carried out. Some factors were further scrutinized for associations using the Pearson correlation coefficient and, finally, a multiple regression model using a stepwise selection of variables was conducted. Results:DGE was diagnosed in 36 (45 %) out of 80 patients (DGE group). The number of patients older than 60 years old in the DGE group was greater than in the group without DGE (32 vs 28 patients, p = 0.009]). Likewise, the number of patients with a preoperative albumin 200 & mu;mol/L (14 vs 8 patients, p = 0.039); postoperative haemorrhage (7 vs 1 patients, p = 0.011); postoperative intraabdominal abscess (12 vs 5 patients, p = 0.017); and postoperative biliary fistula (5 vs 0 patients, p = 0.011), was also greater in the DGE group. Two risk factors were associated with DGE: the patient's age at the time of surgery and preoperative hypoalbuminemia (serum albumin concentration & LE; 35g/L). Conclusions:the patient's age at the time of surgery and the preoperative nutritional status are independent risk factors to the development of DGE after pancreatoduodenectomy

Characteristics and outcomes by ceiling of care of subjects hospitalized with COVID-19 during four waves of the pandemic in a metropolitan area: a multicenter cohort study

Introduction The profiles of patients with COVID-19 have been widely studied, but little is known about differences in baseline characteristics and in outcomes between subjects with a ceiling of care assigned at hospital admission and subjects without a ceiling of care. The aim of this study is to compare, by ceiling of care, clinical features and outcomes of hospitalized subjects during four waves of COVID-19 in a metropolitan area in Catalonia. Methods Observational study conducted during the first (March–April 2020), second (October–November 2020), third (January–February 2021), and fourth wave (July–August 2021) of COVID-19 in five centers of Catalonia. All subjects were adults (>¿18 years old) hospitalized with a proven SARS-CoV-2 infection and with therapeutic ceiling of care assessed by the attending physician at hospital admission. Results A total of 5813 subjects were analyzed. Subjects with a ceiling of care were mainly older (difference in median age of 20 years), with more comorbidities (Charlson index 3 points higher) and with fewer clinical signs at baseline than patients without a ceiling of care. Some features of their clinical profiles changed among waves. There were differences in treatments received during hospital admission across waves, but not between subjects with and without a ceiling of care. Subjects with a ceiling of care had a death incidence more than four times the death incidence of subjects a without a ceiling of care (risk ratio (RR) ranging from 3.5 in the first wave to almost 6 in the third and fourth). Incidence of severe pneumonia and complications for subjects with a ceiling of care was around 1.5 times the incidence in subjects without a ceiling of care. Discussion Analysis of hospitalized subjects with SARS-CoV-2 infection should be stratified according to therapeutic ceiling of care to avoid bias and outcome misestimation.This study was partially funded by Secretaria d’Universitats i Recerca del Departament d’Empresa i Coneixement de la Generalitat de Catalunya (2020PANDE00148).Peer ReviewedPostprint (published version
