Impact of COVID-19 Lockdown on Food Consumption and Behavior in France (COVISTRESS Study).

The COVID-19 pandemic and subsequent lockdowns modified work environments, lifestyles, and food consumption. Eating habits and mood changes in a French population during the first lockdown were examined using an online self-reported questionnaire with REDCap software through the COVISTRESS.ORG website. In 671 French participants, the main changes during lockdown were increased stress levels (64 [23; 86] vs. 3 [0; 18]) and sedentary behavior (7 [4; 9] vs. 5 [3; 8] hours per day), a deterioration in sleep quality (50 [27; 83] vs. 70 [48; 94]) and mood (50 [30; 76] vs. 78 [50; 92]), and less physical activity (2.0 [0.5; 5.0] vs. 3.5 [2.0; 6.0]). Mood was modified, with more anger (56 [39; 76] vs. 31 [16; 50]), more sadness (50 [34; 72] vs. 28 [16; 50]), more agitation (50 [25; 66] vs. 43 [20; 50]), and more boredom (32 [7; 60] vs. 14 [3; 29]). A total of 25% of the participants increased their consumption of alcoholic beverages, 29% their consumption of sugary foods, and 26% their consumption of cocktail snacks. A multiple-correspondence analysis highlights four different profiles according to changes in eating habits, food consumption, lifestyle, and mood. In conclusion, eating habits and lifestyle changes during lockdown periods should be carefully monitored to promote healthy behaviors.

Body Mass Trajectory Affects the Long-Term Occurrence of Metabolic Syndrome in Adult Patients with Severe Obesity.

Independently of absolute BMI values, the amount, onset date, and duration of early body weight gain may influence cardio-metabolic health later in adulthood. Values of cardiac and metabolic variables from a cohort study of morbidly obese patients were retrospectively analyzed to study the association between early weight history and metabolic syndrome (MetS) occurrence in adults. Of 950 patients with severe morbid obesity (age 44.3 ± 13.8 y, BMI 42.5 ± 7.0 kg/m2), 31.4% had started excess weight gain in childhood (CH), 19.9% in adolescence (ADO), and 48.7% in adulthood (AD). Despite different BMI values, MetS prevalence (57.8%) was not significantly different in the three groups (54.4% CH vs. 57.7% ADO vs. 59.8% AD, p = 0.59). The overweight onset period was not significantly associated with the development of MetS in adults (ADO: OR = 1.14 [0.69-1.92], p = 0.60; AD: OR = 0.99 [0.62-1.56], p = 0.95) despite a higher BMI in the early obesity onset group. Weight gain of more than 50% after age 18 years significantly increased the risk of MetS (OR = 1.75 [1.07-2.88], p = 0.026). In addition to crude BMI values, analysis of body mass trajectories is a relevant clinical tool in the assessment of metabolic risk, suggesting that the magnitude of weight gain may be more important for metabolic syndrome progression than the period of obesity onset.

Severe undernutrition increases bleeding risk on vitamin-K antagonists.

INTRODUCTION: Hemorrhage occurs in 7-10% of patients treated with vitamin K antagonist (VKA), with major bleeding in 1-3%. Impact of nutritional status on the bleeding risk of patients on anticoagulants is still poorly documented. Our study aimed to analyze the link between the nutritional status of patients on VKA and the occurrence of hemorrhagic events. We also analyzed micronutrients status. METHODS: A case-control, monocentric, and prospective study was conducted from August 2012 to October 2015. The case patients were those presenting with major bleeding and control patients those without any bleeding under VKA treatment. RESULTS: Overall, 294 patients under VKA treatment were paired according to age, gender, and index normalized ratio (INR). Out of these, 98 (33.3%) had major bleeding and 196 (66.7%) did not have any bleeding. Additionally, more than two-thirds of patients displayed undernutrition, which was more prevalent in bleeding than non-bleeding patients (OR = 1.85, CI95%: 1.07-3.21). There was a higher bleeding risk for those with severe undernutrition (OR = 2.66, CI95%: 1.58-4.46), with no difference found concerning moderate undernutrition. Bleeding patients had lower plasma-zinc concentrations than non-bleeding patients (9.4 ± 3.6 vs. 10.5 ± 3.7 µmol/L, p = 0.003); among them, there was a higher rate of patients with plasma zinc under 5 µmol/L (9% vs. 2%, p < 0.001). CONCLUSION: Patients with undernutrition on VKA exhibit a significantly higher bleeding risk, which increases three-fold in case of severe undernutrition. The evaluation of nutritional status provides additional, valuable prognosis information prior to initiating VKA therapy. CLINICALTRIALS. GOV NUMBER: NCT01742871.

Circulating 20S proteasome for assessing protein energy wasting syndrome in hemodialysis patients.

Protein energy wasting (PEW) including muscle atrophy is a common complication in chronic hemodialysis patients. The ubiquitin proteasome system (UPS) is the main proteolytic system causing muscle atrophy in chronic kidney disease and proteasome 20S is the catalytic component of the UPS. Circulating proteasome 20S (c20S proteasome) is present in the blood and its level is related to disease severity and prognosis in several disorders. We hypothesized that c20S proteasome could be related with muscle mass, other PEW criteria and their evolution in hemodialysis patients. Stable hemodialysis patients treated at our center for more than 3 months were followed over 2 years. C20S proteasome assay was performed at baseline. Biological and clinical data were collected, muscle mass was assessed by multi-frequency bio-impedancemetry, and nutritional scores were calculated at baseline, 1 year and 2 years. Hospitalizations and mortality data were collected over the 2 years. Forty-nine patients were included. At baseline, the c20S proteasome level was 0.40[0.26-0.55] µg/ml. Low muscle mass as defined by a lean tissue index (LTI) < 10th in accordance with the International Society of Renal Nutrition and Metabolism guidelines was observed in 36% and PEW in 62%. Increased c20S proteasome levels were related with LTI at baseline (R = 0.43, p = 0.004) and with its 2 year-variation (R = -0.56, p = 0.003). Two-year survival rate was not different between higher and lower c20S proteasome values (78.9 vs 78.4%, p = 0.98 log-rank test). C20S proteasome is not a good marker for assessing nutritional status in hemodialysis patients and predicting patient outcomes.

[Potentially inappropriate prescribing cardiovascular medications in the aged population: prospective study in a district hospital centre (France)]. / Grande fréquence des prescriptions médicamenteuses à visée cardiovasculaire potentiellement inappropriées dans la population âgée.

OBJECTIVES: Cardiovascular disease is a leading cause of morbidity and mortality in the elderly population. We evaluated the adequacy of prescribing (miss and under used) with respect to STOPP-START criteria. METHODS: A sample of 100 patients hospitalized in cardiovascular specialty divisions (medicine or surgery) or in the different sectors making up the geriatric network (day-care hospital, short or rehabilitation ward, nursing home) has been considered. Drug prescriptions at the admission time were analysed. RESULTS: Eight hundred and seventy-four prescriptions were analysed. In 65% of patients, from 5 to 10 medications were prescribed and in 28% over 10. Fifty-four percent of patients had, at least, one potentially inappropriate prescription (PIP) by STOPP. Among them, 48% of PIP prescriptions contained 1, 41% 2 and 11% 3 or more. The omission of one medication according to START criteria concerned 57% of the sample. Among them, 46% had one omission, 44% 2 to 3 and 10% 4 omissions or over. The cardiovascular system is the one most concerned by the PIP. Whether 28.1% of the PIP by STOPP criteria concerned cardiovascular drugs, the omission of prescription, according to START criteria, was 41.8%. There was no significant difference between the different settings studied. There was no effect of age or sex on the impact of PIP (P>0.20) or being polymédiqué (P=0.44). According to the criteria STOPP-A, the prescription of antiplatelet (indication and dose) was highlighted. Prescribing omission also concerned antiplatelet agents but also statins in patients with atherosclerosis as well as antiplatelet and anticoagulant in patients with permanent atrial fibrillation and inhibitor of angiotensin converting enzyme (ACE) after myocardial infarction or with chronic heart failure. CONCLUSION: Potentially inappropriate prescribing medications were very common in elderly patients with cardiovascular conditions. They concerned as much as underusing of important drugs with potential benefits and prescribing commission of treatment that did not fit with patients' comorbidities and/or characteristics.
