The American Association for the Study of Liver Diseases (AASLD) updated and published the Practice Guidance for the Diagnosis and Management of Nonalcoholic Fatty Liver Disease (NAFLD) in July 2017, which provides recommendations for the accurate diagnosis, treatment, and effective prevention of NAFLD. Related metabolic diseases should be considered during the initial evaluation of patients suspected of NAFLD. Noninvasive diagnostic techniques including transient elastography, magnetic resonance elastography, and serum biochemical models should be used to evaluate the development and progression of liver fibrosis in patients with NAFLD...

Hypovitaminosis D is common in obese patients and persists after roux-en-Y gastric bypass and sleeve gastrectomy. Several societies recommend screening for vitamin D deficiency before bariatric surgery, and replacement doses of 3000 IU/d and up to 50,000 IU 1 to 3 times per week, in case of deficiency, with periodic monitoring. These regimens are mostly based on expert opinion. Large trials are needed to assess the vitamin D dose response, by type of bariatric surgery, and evaluate the effect on surrogate markers of skeletal outcomes...

INTRODUCTION: Bariatric surgeries are the only effective long-term treatment in obese patients. The innovation of laparoscopic gastric plication (LGP) raised some questions about its effectiveness compared to traditionally used techniques such as laparoscopic sleeve gastrectomy (LSG). We tried to answer some of these questions. MATERIALS AND METHODS: We investigated 70 patients in a randomized clinical trial (IRCT2013123012294N5) from 2012 to 2015. Thirty-five patients were randomly assigned to each LSG or LGP group, using sealed envelope method...

BACKGROUND: Bariatric surgery is an effective therapy for morbid obesity but may reduce calcium absorption and significantly decrease the bone mineral density. This study examined the prevalence of secondary hyperparathyroidism (SHPT) in obese subjects during follow-up after different bariatric surgeries. We investigated predictors of SHPT. METHODS: We enrolled 1470 obese subjects undergoing bariatric/metabolic surgery with at least 1-year follow-up, including 322 patients undergoing Roux-en-Y gastric bypass (RYGB), 695 undergoing single anastomosis (mini-) gastric bypass (SAGB), 93 undergoing laparoscopic adjustable gastric banding (LAGB), and 360 undergoing sleeve gastrectomy (SG)...

Obesity is a growing public health problem in France, but modifiable co-morbidities in obese patients during their hospital admissions excluding bariatric surgery are lacking. Data were extracted from the French national hospital discharge database. Data on patient admissions, age, gender, and length of stay were extracted by selecting any stay coded primary as obesity. Obesity was defined as body mass index (BMI) between 30-39 kg/m², and morbid obesity as BMI≥40 kg/m². Only modifiable co-morbidities frequently diagnosed during the 6-year period with a rate≥3% were chosen...

PURPOSE OF REVIEW: Vitamin D is essential for bone health, and may also have important functions in immunity and other systems. Vitamin D deficiency is common, and testing and supplementation is increasing. Serum vitamin D is lower in obese people; it is important to understand the mechanism of this effect and whether it indicates clinically significant deficiency. RECENT FINDINGS: Vitamin D is fat soluble, and distributed into fat, muscle, liver, and serum. All of these compartments are increased in volume in obesity, so the lower vitamin D likely reflects a volumetric dilution effect and whole body stores of vitamin D may be adequate...

PURPOSE OF REVIEW: This article provides an update on the clinical presentation and management of neurologic disease related to key nutrient deficiencies. RECENT FINDINGS: Major advances have been made in understanding the pathway related to vitamin B12 absorption and distribution. It is now known that deficiencies of vitamin B12 and copper have similar neurologic manifestations. Bariatric surgery is a risk factor for both. Alcoholism is just one of the many causes of thiamine deficiency...

Androgens and estrogens play a key role regarding sexual life and reproduction. Along with hypotestosteronemia, obese men exhibit a 2-fold increase in estradiol concentration, adversely infl uencing these parameters. Estrogens and adipokines also infl uence bone metabolism, exerting a direct effect on vitamin D, calcium homeostasis and bone health. Bariatric procedures normalize some sex hormones, and may reverse several obesity-related conditions. Estrogens levels may remain elevated postoperatively, and despite its protective effect on the skeleton, bariatric patients are more prone to fractures when compared to the general population...

The high prevalence of obesity is a worldwide problem associated with multiple comorbidities, including cardiovascular diseases. Vitamin D deficiency with secondary hyperparathyroidism is common in obese individuals and can be aggravated after bariatric surgery. Moreover, there is no consensus on the optimal supplementation dose of vitamin D in postbariatric surgical patients. We present new data on the variability of 25(OH)D response to supplementation in postmenopausal obese women. It is important to recognize and treat vitamin D deficiency before bariatric surgery to avoid postoperative complications, such as metabolic bone disease with associated high fracture risk...
