REVIEW
Michael A Via, Jeffrey I Mechanick
PURPOSE OF REVIEW: The continued success of bariatric surgery to treat obesity and obesity-associated metabolic conditions creates a need for a strong understanding of clinical nutrition both before and after these procedures. RECENT FINDINGS: Surgically induced alteration of gastrointestinal physiology can affect the nutrition of individuals, especially among those who have undergone malabsorptive procedures. While uncommon, a subset of patients may develop protein-calorie malnutrition...

BACKGROUND: Bariatric-metabolic surgery has emerged as an attractive option that offers significant and durable weight loss in the treatment of clinically severe obesity. Given the high prevalence of obesity, and growing numbers of bariatric-metabolic surgeries performed, primary care physicians increasingly encounter patients who have had, or are considering, bariatric-metabolic surgery. OBJECTIVE: The aim of this article is to provide guidance on common issues pertaining to bariatric-metabolic surgery that general practitioners (GPs) face, including patient selection, preoperative work-up, acute and long-term complications following the surgery, and long-term lifestyle and nutritional support...

Background & Aims: TLR9 deletion protects against steatohepatitis due to choline-amino acid depletion and high-fat diet. We measured TLR9 in human NASH livers, and tested whether TLR9 mediates inflammatory recruitment in three murine models of NAFLD. Methods: We assayed TLR mRNA in liver biopsies from bariatric surgery patients. Wildtype (Wt) , appetite-dysregulated Alms1 mutant (foz/foz),Tlr9(-/-), and Tlr9(-/-).foz/foz C57BL6/J mice and bone marrow (BM) chimeras were fed 0.2% cholesterol, high-fat, high sucrose (atherogenic[Ath]) diet or chow, and NAFLD activity score (NAS)/NASH pathology, macrophage/neutrophil infiltration, cytokines/chemokines and cell death markers measured in livers...

PURPOSE OF REVIEW: Type 2 diabetes (T2D) is a growing public health problem in youth, but conventional treatments are often insufficient to treat this disease and its comorbidities. We review evidence supporting an emerging role for bariatric surgery as a treatment for adolescent T2D. RECENT FINDINGS: Paralleling what has been seen in adult patients, bariatric surgery dramatically improves glycemic control in patients with T2D. In fact, remission of T2D has been observed in as many as 95-100% of adolescents with diabetes after bariatric surgery, particularly vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB) surgery...

Obesity, defined as a body mass index >30 kg/m(2), is a growing worldwide epidemic currently effecting 1 in 10 adults, with rates as high as 40% in the United States. The only proven long-term treatment of severe obesity on a population level is surgical modification of the gastrointestinal anatomy to induce weight loss, termed bariatric surgery. With adequate physician guidance and appropriate candidate criteria, bariatric surgery is an option for effective long-term treatment of obesity and its related comorbidities...

Excessive fat deposition in obesity has a multifactorial aetiology, but is widely considered the result of disequilibrium between energy intake and expenditure. Despite specific public health policies and individual treatment efforts to combat the obesity epidemic, >2 billion people worldwide are overweight or obese. The central nervous system circuitry, fuel turnover and metabolism as well as adipose tissue homeostasis are important to comprehend excessive weight gain and associated comorbidities. Obesity has a profound impact on quality of life, even in seemingly healthy individuals...

BACKGROUND: Fibroblast growth factor 21 (FGF21) has been suggested to be an endocrine signal of nutritional status and an active regulator of metabolism. However, there is no agreement on the effect of weight-loss therapies on circulating levels of FGF21 in humans. OBJECTIVE: To assess FGF21 circulating levels in adiposity excess and after different weight-loss strategies prescribed in five different groups from four independent centers. SUBJECTS AND METHODS: Body composition, ketosis, insulin sensitivity and FGF21 were evaluated in 181 excess body weight and 14 normal-weight subjects...

Obesity is associated with hypothalamic inflammation (HI) in animal models. In the present study we examined the mediobasal hypothalamus (MBH) of 57 obese human subjects and 54 age- and sex- matched non-obese controls by MRI and analyzed the T2-hyperintensity as a measure of HI. Obese subjects exhibited T2-hyperintensity in the left but not the right MBH which was strongly associated with systemic low-grade inflammation. MRI-spectroscopy revealed the number of neurons in the left hypothalamic region to be similar in obese versus control subjects suggesting functional but not structural impairment due to the inflammatory process...

BACKGROUND: Obesity leads to olfaction alterations, and this can further impact food choices, appetite, and nutritional status. Bariatric procedures induce weight loss and change in taste and smell perception, but more information is needed, especially using objective olfaction tests. METHODS: A prospective study was conducted during 6 months, with candidates to laparoscopic gastric bypass at a single institution. A preoperative nasofibroscopy and gross smell identification test (The Pocket Smell Test ®) were performed in those meeting the inclusion criteria...

INTRODUCTION: Recently, the incidence of obesity, especially extreme obesity, has significantly increased. It is connected with inappropriate lifestyle, including a high calorie diet, psychological and genetic factors, some medications, diseases or infectious factors. Nowadays, the consumption of food is not only to satisfy a physiological need, but also fulfils psychological needs. The most effective method of morbid obesity treatment is metabolic surgery. Moreover, food is considered to be a reward and method of coping with stress...
