Changes in Bone Mineral Density Following Weight Loss Induced by One-Anastomosis Gastric Bypass in Patients with Vitamin D Supplementation.

Background: Little is known about changes in bone mineral density (BMD) following weight loss after one-anastomosis gastric bypass (OAGB) and the role of serum vitamin D and its supplementation on bone metabolism. We evaluated BMD after OAGB as a function of vitamin D supplementation with respect to a minimum threshold of 25-hydroxy-vitamin-D [25(OH)D] concentration, which could prevent or decelerate an eventual bone loss.

Methods: Fifty bariatric patients who participated in the randomized controlled trial were included in this analysis.

Using digital photography in a clinical setting: a valid, accurate, and applicable method to assess food intake.

Background/objectives: Regular monitoring of food intake is hardly integrated in clinical routine. Therefore, the aim was to examine the validity, accuracy, and applicability of an appropriate and also quick and easy-to-use tool for recording food intake in a clinical setting.

Subjects/methods: Two digital photography methods, the postMeal method with a picture after the meal, the pre-postMeal method with a picture before and after the meal, and the visual estimation method (plate diagram; PD) were compared against the reference method (weighed food records; WFR).

Gradual reduction of free sugars in beverages on sale by implementing the beverage checklist as a public health strategy.

Background: Sugar-sweetened beverages (SSBs) are a major source of free sugar intake and contribute to obesity and obesity-related diseases. Therefore, we analyzed the effect of a gradual sugar reduction strategy within the so-called 'beverage checklist' on free sugar content in beverages on sale in Austria.

Methods: From 2010 until 2017, data on the amount of free sugar of sweetened beverages (sweetened with sugars, fruit juice and artificial sweeteners) with 0.

Sugar-Sweetened Beverages and Weight Gain in Children and Adults: A Systematic Review from 2013 to 2015 and a Comparison with Previous Studies.

Objective: Partly inconsistent findings from previous reviews have fueled discussions on the impact of sugar-sweetened beverages (SSBs) on obesity development. The aim was to systematically review the recent evidence in children and adults.

Methods: Data were retrieved from the databases MEDLINE, EMBASE, and Cochrane library for the period January 2013 to October 2015.

Long-Term Weight-Loss Maintenance by a Meal Replacement Based Weight Management Program in Primary Care.

Objective: Structured obesity treatment programs at primary care level are becoming increasingly important. However, evidence from current treatment approaches in the long term is lacking. In view of this fact we evaluated a standardized, meal replacement-based weight loss program (myLINE®; AENGUS, Graz, Austria) according to the currently applicable guidelines.

Vitamin D Loading Is Superior to Conventional Supplementation After Weight Loss Surgery in Vitamin D-Deficient Morbidly Obese Patients: a Double-Blind Randomized Placebo-Controlled Trial.

Background: Bariatric patients often suffer from vitamin D deficiency (VDD), and both, morbid obesity and VDD, are related to non-alcoholic fatty liver disease. However, limited data are available regarding best strategies for treating VDD, particularly, in bariatric patients undergoing omega-loop gastric bypass (OLGB). Therefore, we examined the efficacy and safety of a forced vitamin D dosing regimen and intervention effects in liver fibrotic patients.

The Effect of Roux-en-Y vs. Omega-Loop Gastric Bypass on Liver, Metabolic Parameters, and Weight Loss.

Background: Omega-loop gastric bypass (OLGB) results in weight loss (WL) but data on its impact on liver and glucose metabolism compared to Roux-en-Y gastric bypass (RYGB) is lacking. Therefore, the aim of this study was to compare the development of hepatic and metabolic markers as well as WL between the above-mentioned surgical groups during the first postoperative year.

Methods: We retrospectively evaluated the respective parameters in non-diabetic morbidly obese patients who underwent either RYGB (n = 25) or OLGB (n = 25).

Worksite Prevalence of (un)Diagnosed Cardiovascular Risk Factors From a Health-Check-Program in An Austrian Company.

Objective: This investigation aims to determine cardiovascular disease risk profile in a cohort of employees.

Methods: In 704 participants, within the Special Institute for Preventive Cardiology And Nutrition health-check-program, body mass index, waist circumference, blood pressure (BP), lipids, glucose, and 10-year cardiovascular disease risk were assessed.

Results: Mean age was 37 (10) years (20% women) with 25.

Changes of dietary patterns during participation in a web-based weight-reduction programme.

Objective: To examine the weight-loss success associated with distinct dietary patterns and to determine changes of these dietary patterns during participation in a web-based weight-reduction programme.

Design: Factor analysis was used to identify the dietary patterns of twenty-two food groups that were administered in 14 d dietary protocols at baseline and after 3 months. Successful weight loss (≥5% of initial weight) and BMI were calculated.

The link between obesity and vitamin D in bariatric patients with omega-loop gastric bypass surgery - a vitamin D supplementation trial to compare the efficacy of postoperative cholecalciferol loading (LOAD): study protocol for a randomized controlled trial.

Background: Beyond its classical role in calcium homoeostasis and bone metabolism, vitamin D deficiency has been found to be associated with several diseases, including diabetes, non-alcoholic fatty liver disease, and even obesity itself. Importantly, there are limited data on therapeutic strategies for vitamin D deficiency in bariatric patients, and the procedure-specific guidelines may not be sufficient. To improve long-term outcomes, nutritional screening and appropriate supplementation to prevent nutrient deficiencies are urgently needed.

Influence of intravenous thiamine supplementation on blood lactate concentration prior to cardiac surgery: A double-blinded, randomised controlled pilot study.

Background: Stress related to surgery and critical illness depletes thiamine, essential in energy metabolism, and might result in high blood lactate concentrations and higher mortality.

Objectives: We hypothesised that thiamine supplementation would increase blood concentration of thiamine and reduce blood lactate concentration postoperatively. Moreover, we aimed to identify the prevalence of, and risk factors for, high blood lactate concentrations.

Effects of omega-loop gastric bypass on vitamin D and bone metabolism in morbidly obese bariatric patients.

Background: Bariatric patients often suffer from nutrient deficiencies. Little is known about vitamin D levels and bone metabolism in patients undergoing omega-loop gastric bypass (OLGB). We, therefore, evaluated parameters of vitamin D metabolism preoperatively and during the first postoperative year.

Evaluation of a meal replacement-based weight management program in primary care settings according to the actual European Clinical Practice Guidelines for the Management of Obesity in Adults.

Introduction: The purpose of this study was the evaluation of a weight loss program in primary care settings with respect to the European Clinical Practice Guidelines for the Management of Obesity in Adults with regard to the long-term success of changes in body weight and composition.

Methods: Overweight and obese patients (n = 1167) who underwent a standardized meal replacement-based weight loss program (myLINE(®), AENGUS, Austria) in primary care settings were included in this evaluation. Body composition was measured by conventional anthropometry and bioelectrical impedance analysis (AKERN BIA101(®), BIACORPUS RX4000(®), SoftwareBodycomp Version 8.

Nutritional intervention and physical training in malnourished frail community-dwelling elderly persons carried out by trained lay "buddies": study protocol of a randomized controlled trial.

Background: In elderly persons frailty and malnutrition are very common and can lead to serious health hazards such as increased mortality, morbidity, dependency, institutionalization and a reduced quality of life. In Austria, the prevalence of frailty and malnutrition are increasing steadily and are becoming a challenge for our social system. Physical training and adequate nutrition may improve this situation.
