ACTA ENDOCRINOLOGICA (BUC)

Context. Pancreatic neuroendocrine tumours (PanNETs) are rare pancreatic neoplasms. PanNETs can be treated by multimodal approach including surgery, locoregional and systemic therapy. Objective. The aim of the present study is to evaluate predictive factors of overall survival in patients with PanNETs surgically treated at a single center. Subjects and methods. The study group consisted of 120 patients with PanNETs who had undergone surgery at the Center of Digestive Diseases and Liver Transplantation of Fundeni Clinical Institute, Bucharest, Romania. Surgical resection of the primary tumor was performed in 110 patients. Results. Tumor size > 2 cm (p=0.048) (90% CI) lymph node involvement (p=0.048), ENET grade (p<0.001), distant metastases (p<0.001), Ki 67 index (<2%, 2-5%, 5-10%, 10-20%, >20%) (p<0.001) were identified as significant prognostic factors for OS on univariate analysis. Using multivariate Cox proportional regression model we found that distant metastases and Ki 67 index were independent risk factors for the survival outcome. Conclusions. Surgery with curative intent should be considered in all cases if clinically appropriate and technically feasible. High grade (Ki67 index ≥10%) tumours were associated with a 2- fold increase in risk of death as compared to those with a Ki67 <10%

Context. In this study we compared daily calorie restriction, and intermittent calorie restriction in overweight and class 1 obese patients. Findings are these diets correct metabolic parameters and intermittent calorie restriction diet regimen increases muscle strength. Aim. We investigated the effects on metabolic, anthropometric values and muscle in Intermittent Fasting (IF) and Continuous Calorie Restriction (CCR) groups in adult overweight and class 1 obese patients. Material and Methods. The patients were randomly divided into 3 groups: IF group (n=23), CCR group (n=21), and control group (n=22). Fat mass, and basal metabolic rate were recorded. Fat-Free Mass Index (FFMI) was calculated. Handgrip strength was measured. Walking speed test was performed. The 'International Physical Activity Questionnaire was administered to the patients. Weight, body mass index, fat mass, muscle mass, FFMI, waist circumference, right and left arm circumference, right and left calf circumference values decreased significantly and similarly compared to the beginning at the end of 6 months in the IF and CCR groups (p<0.05). A statistically significant increase was found in hand grip strength test measurements in the IF groups. Conclusions. IF and CCR diets enhance metabolic functions while reducing muscle mass. Despite this decrease, the IF diet increases muscular strength.
