INTRODUCTION: Although pregnancy after bariatric surgery is related to risk reduction, nutritional complications may occur. This study aimed to evaluate nutritional and biochemical indicators of women who became pregnant after Roux en Y gastric bypass (RYGB). MATERIALS AND METHODS: We carried out a retrospective study with women who became pregnant after RYGB. We evaluated anthropometric, biochemical, and dietary intake indicators in the preoperative period and before, during, and after pregnancy by analysis of medical records...

PURPOSE: Percutaneous kyphoplasty (PKP) is a minimally invasive procedure for the treatment of osteoporotic vertebral compression fractures (OVCFs). It is generally considered that there is little blood loss during the surgery. However, a significant perioperative hidden blood loss (HBL) is neglected. This study was to examine the amount of HBL and determine the influential factors during PKP. METHODS: From January 2015 to January 2016, 115 patients with OVCFs who were scheduled to have a PKP were enrolled in this study...

IMPORTANCE: In obese patients with type 2 diabetes (T2DM), the marked weight loss following bariatric surgery is accompanied in a consistent number of cases by T2DM resolution or control. The clinical need of preoperative parameters reliable in predicting a positive metabolic outcome at long term following the operation has then emerged. OBSERVATION: A cohort of 135 consecutive T2DM patients with a wide range of body mass index (BMI) at more than 5 years following biliopancreatic diversion (BPD) was considered...

PURPOSE: Rising rates of obesity have been recently associated to the novel concept of food addiction (FA). The Yale Food Addiction Scale (YFAS) is the most widely used measure for examining FA (1) and analysis of its reliability and validity is expected to facilitate empirical research on the construct. Here, we tested the psychometric properties of a Portuguese version of the YFAS (P-YFAS), establishing its factor structure, reliability and construct validity. METHODS: Data were obtained from 468 Portuguese individuals, 278 sampled from non-clinical populations, and 190 among obese candidates for weight-loss surgery...

REVIEW
Joseph M Pappachan, Ananth K Viswanath
PURPOSE OF REVIEW: The global prevalence of "diabesity"-diabetes related to obesity-is increasing steadily over the past few decades because of the obesity epidemic. Although bariatric surgery is an effective treatment option for patients with diabesity, its limited availability, invasiveness, relatively high costs and the potential for surgical and postsurgical complications restrict its widespread use. Therefore, medical management is the only option for a majority of patients with diabesity...

Bariatric surgery results in notable weight loss and alleviates hyperglycemia in patients with type 2 diabetes (T2D). In this study, we aimed to characterize the vascular effects of a mixed-meal and of infusion of exogenous glucose-dependent insulinotropic polypeptide (GIP) in the splanchnic region in ten obese patients with T2D before and after bariatric surgery and in ten lean controls. The experiments were carried out on two separate days. Pancreatic and intestinal blood flow (BF) were measured at baseline, 20 and 50 minutes with (15)O-water using positron emission tomography and magnetic resonance imaging (PET/MRI)...

Roux-en-Y gastric bypass (RYGB) surgery is widely used in the management of morbid obesity. RYGB improves metabolism independently of weight loss by still unknown mechanisms. Bile acids (BAs) are good candidates to explain this benefit, since they regulate metabolic homeostasis and their systemic concentrations increase upon RYGB. Here we analyzed the mechanisms underlying the increase in systemic BA concentrations after RYGB and the role of the liver therein. To this aim, we used the Göttingen-like minipig, a human-size mammalian model, which allows continuous sampling and simultaneous analysis of pre-hepatic portal and systemic venous blood...

PURPOSE OF REVIEW: Obesity, a growing global health problem, contributes to the development of heart failure. However, increased BMI seems protective for those with established disease, a phenomenon known as the 'obesity paradox'. In this review, we outline the mechanism through which obesity can contribute to the development of heart failure, explore the concept of obesity paradox, and highlight the challenges that obesity presents for advanced heart failure therapy. RECENT FINDINGS: Although the mechanism underlying the obesity paradox is complex, meta-analysis shows that intentional weight loss through bariatric surgery can indeed improve cardiac structure and function...

REVIEW

Surgical interventions for weight-related diseases (SWRD) may have substantial and sustainable effect on weight reduction, also leading to a higher remission rate of type 2 diabetes (T2D) mellitus than any other medical treatment or lifestyle intervention. The resolution of T2D after Roux-en-Y gastric bypass (RYGB) typically occurs too quickly to be accounted for by weight loss alone, suggesting that these operations have a direct impact on glucose homeostasis. The mechanisms underlying these beneficial effects however remain unclear...

PURPOSE: Bariatric surgery has been associated with bone remodeling changes. The action of adipokines on the expression of receptor activator of nuclear factor kappa β ligand (RANKL) and osteoprotegerin (OPG) and on an increase in sclerostin could be related to these changes. MATERIALS AND METHODS: This study aimed to assess the repercussions of weight loss, fat mass (FM), and fat-free mass (FFM) loss and biochemical and hormonal changes on bone remodeling markers after Roux-en-Y gastric bypass (RYGB)...

Gastroesophageal reflux disease (GERD) is a common disorder that has a well-established connection with obesity. To ameliorate the morbidity associated with obesity, bariatric procedures have become an established pathway to accomplish sustained weight loss. In some procedures, such as with the Roux-en-Y gastric bypass surgery, weight loss is also accompanied by the resolution of GERD symptoms. However, other popular bariatric surgeries, such as the sleeve gastrectomy, have a controversial impact on their effect on reflux...

PURPOSE: Undernutrition during hospitalization increases the risk of nosocomial infection and lengthens the disease courses. The aim of this study was to evaluate the risk factors of weight loss during hospitalization in children. METHODS: All the patients who were admitted in general wards between April and May 2014 were enrolled. Patients aged >18 years and discharged within 2 days were excluded. Weight loss during hospitalization was defined as a decrease in body weight of >2% in 8 hospital days or on the day of discharge...

INTRODUCTION: Since the 1990s, a number of weight loss medications have been removed from the USA and or European market because of adverse events associated with these medications. These medications include fenfluramine (heart valve thickening), sibutramine (cardiovascular risk) and rimonabant (depression). This history may affect a patient's desire to consider weight loss medications as an option for weight management. OBJECTIVE: This descriptive study was designed to observe what treatment options the geriatric patient (age 65 or higher) seeking weight loss would like to consider, as well as the reasons they felt they struggled with overweight or obesity...

BACKGROUND: Deficits in executive functions are related to poorer weight loss after bariatric surgery; however, less is known about the role that these deficits may play during participation in nonsurgical weight loss programmes. This study examined associations between objectively measured executive functions and weight loss during participation in a medically supervised weight loss programme. METHODS: Twenty-three adult patients (age 50.4 ± 15.1, BMI 44.2 ± 8...

BACKGROUND: Laparoscopic sleeve gastrectomy (SG) as a single-stage procedure for the treatment of morbid obesity is becoming increasingly popular. In undeveloped countries, the linear staples required to create the sleeve are not always available because of their high cost. As an alternative to the staples, the bipolar vessel sealer device could be used in bariatric surgery to divide and temporarily seal the stomach. SETTINGS: Universidad Central de Venezuela, Caracas, Venezuela...

BACKGROUND: Psychosocial factors contribute to poorer weight loss outcomes following bariatric surgery; however, findings on associations between preoperative psychiatric diagnoses, psychological testing, and weight loss are inconsistent. OBJECTIVES: Examine associations between presurgical psychiatric diagnoses derived from a semi-structured clinical interview and test scores from the Minnesota Multiphasic Personality-Inventory-2 - Restructured Form (MMPI-2-RF) and 5-year Body Mass Index (BMI) outcomes...

BACKGROUND: The traditional duodenal switch is performed using a Roux-en-Y configuration. This procedure has proven to be the most effective procedure for long-term weight loss and co-morbidity reduction. Recently, stomach intestinal pylorus sparing surgery (SIPS) has been introduced as a simpler and potentially safer variation of the duodenal switch (DS). It is a single anastomosis end-to-side proximal duodeno-ileal bypass with a sleeve gastrectomy. In this study, we compare our outcomes between biliopancreatic diversion with duodenal switch (BPD-DS) and SIPS at 2 years...

BACKGROUND: In this study, we sought to analyze the incidence and relevance of von Willebrand factor (VWF) abnormalities in patients undergoing transcatheter aortic valve implantation (TAVI), especially on perioperative bleeding. Furthermore, we hypothesized that, similar to aortic valve surgery, TAVI results in a restoration of VWF abnormalities. METHODS AND RESULTS: We performed a prospective analysis of periinterventional VWF parameters in 74 patients (80±7years, female in 37...

INTRODUCTION: Obesity is an independent risk factor for erectile dysfunction (ED) and lower urinary tract symptoms (LUTS). Bariatric surgery has been shown to improve erectile function and urinary symptoms in medium- to long-term studies (3- to 12-month postoperative follow-up). AIM: To investigate the early effect (1 month postoperatively) of bariatric surgery on ED and LUTS, which has not previously been investigated. METHODS: Morbidly obese men (body mass index > 35 kg/m(2)) undergoing bariatric surgery were asked to complete the International Index of Erectile Function (IIEF) and International Prostate Symptom Score (IPSS) questionnaires before surgery and 1, 3, and 6 months after surgery...

Obesity has been associated with chronic kidney disease in adult studies, but little data exist in pediatrics. Nehus et al. offer the first study to show that bariatric surgery in severely obese adolescents is associated with improved renal outcomes. Despite limitations, this study provided compelling evidence that aggressive weight loss intervention can improve renal outcomes in young, severely obese subjects. Further investigation is required to determine mechanisms by which this may occur.
