The effect of nutrition on sleeve gastrectomy patients' weight loss, biochemical measurements, and comorbids: A clinical study.

BACKGROUND: This study investigates the effect of a nutrition program applied to patients as per bariatric surgery protocol at the sixth month postoperative. The study also compares and contrasts the postoperative findings with preoperative data. METHODS: Twenty severely obese sleeve gastrectomy patients between the ages of 18-65 participated in the study. Energy requirements were calculated as 22 kcal/ideal body weight (kg/day) and protein requirements as 1.5 g/ideal body weight (kg/day). The study evaluates patients' anthropometric and biochemical measurements, body mass index, waist circumference, fat mass (%), weight loss (%), excess weight loss (%), comorbids, and dietary habits at the third and sixth months preoperative and postoperative. Patients' daily macro-micronutrient intake was also calculated. The Friedman Test and Cochran's Q test were performed to determine statistically significant data (p < 0.05). RESULTS: During the first 6 months postoperative, patients lost 34 kg of weight and 16.7% of fat mass, and their percent excess weight loss was measured at 60.2% (<0.0001). Biochemical measurements of the patients revealed that fasting blood glucose, low-density lipoprotein cholesterol, total cholesterol, triglyceride, and calcium levels, which were above the reference range in the preoperative period, were within this range in the postoperative period (<0.0001). Thirteen out of 21 comorbidities, including type 2 diabetes, hypertension, hyperlipidemia, pulmonary problems, and sleep apnea, improved at different rates in the sixth month postoperative. CONCLUSIONS: Thanks to the nutrition program applied as per bariatric surgery protocol, patients lost weight, and their biochemical measurements and comorbids have improved following sleeve gastrectomy.

Novel coronavirus seropositivity and related factors among healthcare workers at a university hospital during the prevaccination period: a cross-sectional study.

BACKGROUND: This study aimed to investigate the specific risk factors for the transmission of novel coronavirus (SARS-CoV-2) among healthcare workers in different campuses of a university hospital and to reveal the risk factors for antibody positivity. METHODS: In this retrospective cross-sectional study, 2988 (82%) of 3620 healthcare workers in a university hospital participated. The coronavirus disease 2019 (COVID-19) antibody was investigated using serum from healthcare workers who underwent COVID-19 antibody testing. The antibody test results of the participants were evaluated based on their work campus, their profession and their workplace. The statistical significance level was p < 0.05 in all analyses. RESULTS: Of the participants in this study, 108 (3.6%) were antibody positive, and 2880 (96.4%) were negative. Antibody positivity rates were greater in nurses compared with other healthcare workers (p < 0.001). Regarding workplace, antibody positivity was greater in those working in intensive care compared to those working in other locations (p < 0.001). CONCLUSIONS: Healthcare workers are at the highest risk of being infected with COVID-19. Those who have a higher risk of infection among healthcare workers and those working in high-risk areas should be vaccinated early and use personal protective equipment during the pandemic. TRIAL REGISTRATION: Retrospective permission was obtained from both the local ethics committee and the Turkish Ministry of Health for this study (IRB No:71522473/050.01.04/370, Date: 05.20.2020).
