BACKGROUND: Although Roux-en-Y gastric bypass (RYGB) induces short-term weight loss and co-morbidity amelioration, long-term data suggest that a subset of patients return to their preoperative body mass index (BMI). OBJECTIVES: To identify the clinical implications of 10-year weight loss failure after RYGB. SETTING: An academic teaching hospital. METHODS: Adults undergoing RYGB (1985-2004) were included in this study (n = 1087)...

Obesity increases the risk of several other chronic diseases and, because of its epidemic proportions, has become a major public health problem worldwide. Alarmingly, a lower proportion of adults have tried to lose weight during the past decade than during the mid-1980s to 1990s. The first-line treatment option for obesity is lifestyle intervention. Although this approach can decrease fat mass in the short term, these beneficial effects typically do not persist. If a large amount of weight loss is not an easily achievable goal, other goals that might motivate people with obesity to adopt a healthy lifestyle should be considered...

Daniel H Bessesen, Luc F Van Gaal
Obesity is a serious and growing worldwide health challenge. Healthy lifestyle choices are the foundation of obesity treatment. However, weight loss can lead to physiological adaptations that promote weight regain. As a result, lifestyle treatment alone typically produces only modest weight loss that is difficult to sustain. In other metabolic diseases, pharmacotherapy is an accepted adjunct to lifestyle. Several anti-obesity drugs have been approved in the USA, European Union, Australia, and Japan including sympathomimetics, pancreatic lipase inhibitors, GABAA receptor activators, a serotonin 2C receptor agonist, opioid antagonist, dopamine-norepinephrine reuptake inhibitor, and glucagon-like peptide-1 (GLP-1) receptor agonists...

Acinetobacter baumannii is a tiny, plump and rod-shaped Gram-negative coccobacillus, notorious as an opportunistic pathogen, which is now being considered by CDC as a serious public health threat. Preventing colonization may be a better therapeutic choice using microbiota to protect against A. baumannii transmission. Human microbiota not only regulates immune homeostasis as well provides essential health benefits therefore discovering the interface due microbiota in host immune system will allow to recognise novel immuno- or microbe-based therapies...

OBJECTIVES: Men and women may lose weight in a different fashion. This study compares the changes in different anatomical regions after a well-controlled weight loss program by sex and initial BMI. METHODS: A total of 180 subjects (48 overweight women, 36 overweight men, and 48 obese women and 48 obese men) were recruited to participate in a 22-week weight loss programme (diet + exercise). RESULTS: Regarding percentage body weight change from baseline, there was no triple interaction (BMI, sex and anatomical region), but there was interaction between BMI and anatomical region (F2,840=34...

Jacqueline Rose, Jan Rillich, Paul A Stevenson
Losing a fight against a conspecific male (social defeat) induces a period of suppressed aggressiveness and general behaviour, often with symptoms common to human psychiatric disorders. Agonistic experience is also discussed as a potential cause of consistent, behavioral differences between individuals (animal "personality"). In non-mammals, however, the impact of single agonistic encounters typically last only hours, but then again studies of repeated intermittent defeat (chronic social defeat) are seldom...

AIMS AND OBJECTIVES: To describe the experiences of patients who have failed to maintain weight loss following the insertion of a Laparoscopic Adjustable Gastric Band (LAGB) for the treatment of morbid obesity. BACKGROUND: Obesity is a global health problem resulting in physical, psychological and economic problems, and presenting challenges for health services. Surgical intervention is an increasingly common approach to treatment, however some patients do not sustain their weight loss following bariatric surgery and little is known about people's longer-term experiences following LAGB insertion...

The gut microbiome is linked to inflammatory bowel disease (IBD) severity and altered in late-stage disease. However, it is unclear how gut microbial communities change over the course of IBD development, especially in regard to function. To investigate microbiome-mediated disease mechanisms and discover early biomarkers of IBD, we conducted a longitudinal metagenomic investigation in an established mouse model of IBD, where damped transforming growth factor β (TGF-β) signaling in T cells leads to peripheral immune activation, weight loss, and severe colitis...

Prior work has yielded mixed results regarding the association between previous weight loss and success in a current weight loss attempt. The present study evaluated differences in baseline psychosocial processes, changes in these over time, and weight loss during a yearlong behavioral weight loss program between individuals who have and have not previously been successful losing weight through self-regulating dietary intake. Individuals with prior success had greater weight losses over time than those without...

Psoriasis is a chronic, relapsing, inflammatory disease that has been associated with Metabolic Syndrome (MS), a cluster of cardiovascular risk factors mainly hypertension, obesity, diabetes mellitus and hyperlipidemia. A 49-year-old male patient presented with extensive plaque psoriasis from past 13 years. Past medications included methotrexate, PUVA therapy, topical immunosuppressants and corticosteroids. His baseline Psoriasis Area and Severity Index (PASI) score was 39.8. The patient was screened and diagnosed with MS as per Alberti's Criteria (his waist circumference was 100 cm, blood pressure was 160/100 mmHg and High Density Lipoprotein (HDL) was 30 mg/dl)...

BACKGROUND: Crops grown under elevated atmospheric CO2 concentrations (eCO2) contain less protein. Crops particularly affected include rice and wheat, which are primary sources of dietary protein for many countries. OBJECTIVES: We aimed to estimate global and country-specific risks of protein deficiency attributable to anthropogenic CO2 emissions by 2050. METHODS: To model per capita protein intake in countries around the world under eCO2, we first established the effect size of eCO2 on the protein concentration of edible portions of crops by performing a meta-analysis of published literature...

OBJECTIVE: To investigate the efficacy and safety of increasing doses of cathine (nor-pseudoephedrine) as a weight-lowering agent in patients with obesity. METHODS: Overweight and obese patients (n = 241, mean BMI 34.6 ± 3.4 kg/m²) were randomly allocated to one of three doses of cathine (16 mg, 32 mg, 53.3 mg) or placebo in addition to a multimodal lifestyle intervention program in a multicenter, double-blind, controlled, dose-finding study for 24 weeks. Primary outcome was weight loss...

BACKGROUND: The decision to lose weight among adolescents is complex and is guided by a number of body-related factors. This study examined the extent of agreement between actual weight, measured as body mass index, and self-perceived weight and assessed their relative importance in weight loss behaviour among Lebanese adolescents. METHODS: Data on 278 adolescents aged 13-17 years were drawn from the nationwide Nutrition and Non-Communicable Disease Risk Factor Survey (Lebanon, 2009)...

BACKGROUND: Arterial stiffness is one of the earliest indicators of changes in vascular wall structure and function and may be assessed using various indicators, such as pulse-wave velocity (PWV), the cardio-ankle vascular index (CAVI), the ankle-brachial index (ABI), pulse pressure (PP), the augmentation index (AI), flow-mediated dilation (FMD), carotid intima media thickness (IMT) and arterial stiffness index-β. Arterial stiffness is generally considered an independent predictor of cardiovascular and cerebrovascular diseases...

Chiye Aoki, Ang D Sherpa
Mature excitatory synapses are composed of more than 1500 proteins postsynaptically and hundreds more that operate presynaptically. Among them, drebrin is an F-actin-binding protein that increases noticeably during juvenile synaptogenesis. Electron microscopic analysis reveals that drebrin is highly enriched specifically on the postsynaptic side of excitatory synapses. Since dendritic spines are structures specialized for excitatory synaptic transmission, the function of drebrin was probed by analyzing the ultrastructural characteristics of dendritic spines of animals with genetic deletion of drebrin A (DAKO), the adult isoform of drebrin...

BACKGROUND: Breast reconstruction is an essential component in the treatment of breast cancer. Postoperative complications after breast reconstruction are common and affect patient satisfaction. Determining independent risk factors using patient characteristics could be advantageous for patient assessment and counseling. METHODS: We retrospectively enrolled 623 consecutive patients who underwent reconstruction with a deep inferior epigastric perforator flap (DIEP), latissimus dorsi flap (LD), lateral thoracodorsal flap (LTDF), or tissue expander with a secondary implant (EXP) in this study...

We present a framework for biodiversity metrics that organizes the growing panoply of metrics. Our framework distinguishes metrics based on the type of information-abundance, phylogeny, function-and two common properties-magnitude and variability. Our new metrics of phylogenetic diversity are based on a partition of the total branch lengths of a cladogram into the proportional share of each species, including: a measure of divergence which standardizes the amount of evolutionary divergence by species richness and time depth of the cladogram; a measure of regularity which is maximal when the tree is perfectly symmetrical so that all species have the same proportional branch lengths; a measure that combines information on the magnitude and variability of abundance with phylogenetic variability, and a measure of phylogenetically weighted effective mean abundance; and indicate how those metrics can be decomposed into α and β components...

BACKGROUND: Despite increasing interest in smartphone apps as a platform for delivery of tobacco cessation interventions, no previous studies have evaluated the prevalence and characteristics of smokers who can access smartphone-delivered interventions. OBJECTIVE: To guide treatment development in this new platform and to evaluate disparities in access to smartphone-delivered interventions, we examined associations of smartphone ownership with demographics, tobacco use and thoughts about quitting, other health behaviors, physical and mental health, health care access, and Internet and technology utilization using a nationally representative sample of US adult smokers...
