ABSTRACT

BACKGROUND: Sarcopenia is associated with negative outcomes in intensive care unit (ICU) patients and during chronic diseases. We aimed to evaluate if low skeletal muscle index (SMI) measured by computed tomography (CT) at the thoracic level is associated with poor outcomes in hospitalized patients with respiratory COVID-19. METHODS: Patients admitted to the hospital between March 1st and June 9, 2020 with a confirmed diagnosis of respiratory COVID-19 in the Emergency Department were included in this retrospective cohort study. SMI was assessed from a transverse CT image at the T12 level. We analysed the association between thoracic SMI and mortality, ICU admissions, infections, length of stay and gravity scores. RESULTS: We included 244 patients, whose median age was 62 (20-95) years, mean body mass index was 28,6 kg/m2, and 34% were obese patients. 102 patients (41,8%) had low thoracic SMI. On multivariable analysis, low thoracic SMI was associated with more infections (OR = 1,88 [1,06-2,98]) and increased length of stay (OR = 1,87 [1,14-3,49]) but not with mortality (OR = 1.37 [0.54-3.52]), whereas it was inversely associated with ICU admission (OR = 5,56 [1,96-16,67]. CONCLUSION: Low SMI measured by CT at the thoracic level T12 is associated with negative outcomes in patients with respiratory COVID-19.

ABSTRACT

BACKGROUND: Healthcare students are future health care providers and serve as role models and coaches to enhance behaviors for healthy lifestyles. However healthcare students face multiple stressors that could lead to adopting risk behaviors. OBJECTIVES: To assess the changes in health risk factors among healthcare students between 2007 and 2015, and to identify specific health behaviors based on the curriculum in a population of healthcare students. METHODS: Two cross sectionnal studies were conducted in 2007 and 2015 among nursing, medical, pharmacy, and physiotherapy students (Rouen, France). During compulsory courses and examination sessions students filled self-administered questionnaires on socio-demographic characteristics and behavior as: tobacco smoking, alcohol consumption, cannabis consumption, eating disorders, regular practice of sport, perceived health, stress and use of psychotropic drugs. RESULTS: 2,605 healthcare students were included (1,326 in 2007 and 1,279 in 2015), comprising 1,225 medical students (47.0%), 738 nursing students (28.3%), 362 pharmacy students (13.9%), and 280 physiotherapy students (10.8%). Between 2007 and 2015, occasional binge drinking and regular practice of sport increased significantly among healthcare students, respectively AOR = 1.48 CI95% (1.20-1.83) and AOR = 1.33 CI95% (1.11-1.60), regular cannabis consumption decreased significantly, AOR = 0.32 CI95% (0.19-0.54). There was no change in smoking or overweight/obese. There was a higher risk of frequent binge drinking and a lower risk of tobacco smoking in all curricula than in nursing students. Medical students practiced sport on a more regular basis, were less overweight/obese, had fewer eating disorders than nursing students. CONCLUSION: Our findings demonstrate a stable frequency of classic behaviors as smoking but a worsening of emerging behaviors as binge drinking among healthcare students between 2007 and 2015. Health behaviors differed according to healthcare curricula and nursing students demonstrated higher risks. As health behaviors are positively related to favorable attitudes towards preventive counseling, therefore healthcare students should receive training in preventive counseling and develop healthy lifestyles targeted according to the health curriculum.

ABSTRACT

Our objective was to evaluate the contribution of monitoring B cell subset depletion after rituximab in patients with rheumatoid arthritis (RA) in order to guide reintroduction to forestall relapse. This prospective, monocentre study included all RA patients receiving two 1-g rituximab infusions at a 15-day interval. The patients were followed clinically and biologically every 2 months until rituximab reintroduction. The physician was blinded to lymphocyte-typing results to diagnose relapse and, hence, retreatment. Among the 39 patients included between March 2010 and December 2011 and followed until April 2013, seven received two rituximab cycles, yielding a total of 46 cycles for analysis. After the two rituximab cycles, the total number of CD19(+) B cells decreased significantly (0·155 versus 0·0002 G/l, P < 0·0001), with complete depletions in all patients of CD19(+) CD38(++) CD24(++) (transitional) (P < 0·0001) and CD19(+) CD27(+) (memory) B lymphocytes. A significant majority of patients relapsed within the 4 months following repopulation of total B (P = 0·036), B transitional (P = 0·007) and B memory (P = 0·01) lymphocytes. CD19(+) B lymphocyte repopulation preceded clinical RA relapse and enabled its prediction 4 months in advance. Hence, monitoring of CD19(+) B lymphocytes could serve as a tool to predict those relapses.

ABSTRACT

BACKGROUND: Superficial cellulitis of the leg (erysipelas) is a frequent skin infection. Abscess formation is the most frequent local complication. Determinants of abscess formation in patients with leg cellulitis have not yet been clearly established. OBJECTIVE: To assess the risk factors for abscess formation in patients with leg cellulitis. METHODS: The clinical, biological and bacteriological records of all patients referred to the dermatology department of a university hospital for superficial cellulitis of the leg during a 3-year period were retrospectively reviewed. Using univariate and multivariate analysis, patients' main characteristics at baseline were compared between the group of patients who developed abscess and the group who did not. RESULTS: A total of 164 patients (93 female, 71 male), mean age 65±18 years, were included. Abscess occurred in 13 cases (8%). The following general factors were positively associated with abscess formation: male sex, smoking, alcohol abuse and delayed introduction of antibiotic treatment. Based on multivariate analysis, only chronic alcohol abuse [odds ratio (OR) 4·3, 95% confidence interval (CI)1·08-20·57] and delayed antibiotic treatment initiation (OR 1·4, 95% CI 1·02-2·04) remained independently associated with abscess formation. CONCLUSIONS: Alcohol abuse and delayed initiation of antibiotic treatment are risk factors for abscess formation in patients with cellulitis of the leg. Patients with these predictors must be monitored carefully for abscess formation.
