The role of staging laparoscopy in complex bariatric surgery.

Clin Obes 2021 May 3:e12460. Epub 2021 May 3.

Department of Upper GI and Bariatric/Metabolic Surgery, North Bristol NHS Trust, Southmead Hospital, Bristol, UK.

Determining which patients will benefit from bariatric surgery is complex; however, in those who have had previous bariatric surgery or extensive abdominal surgery, this can be particularly challenging. Decisions are often made based on assumptions rather than a complete assessment of all the anatomical and physiological factors. Adopting the approach utilised in gastrointestinal surgery with a diagnostic or staging laparoscopy, it may be possible to more accurately stage disease and determine fitness bariatric surgery.

Impacts of Gastrojejunal Anastomotic Technique on Rates of Marginal Ulcer Formation and Anastomotic Bleeding Following Roux-en-Y Gastric Bypass.

Obes Surg 2021 May 3. Epub 2021 May 3.

Atrium Health Weight Management, Section of Bariatric and Metabolic Surgery, Department of Surgery, Atrium Health, 2630 E 7th St Suite 100, Charlotte, NC, 28204, USA.

Background: Marginal ulceration (MU) and bleeding are possible complications following laparoscopic Roux-en-Y gastric bypass (RYGB). Our institution utilizes three techniques for performing the gastrojejunal anastomosis (GJA), providing a means to compare postoperative MU and bleeding as it relates to GJA technique.

Objectives: We sought to analyze the incidence of MU and bleeding between the 25-mm end-to-end anastomosis (EEA) stapler, linear stapler (LS), and robotic hand-sewn (RHS) GJA techniques. Read More

Serum Creatinine-to-Cystatin C Ratio in the Progression Monitoring of Non-alcoholic Fatty Liver Disease.

Front Physiol 2021 7;12:664100. Epub 2021 Apr 7.

Department of Endocrinology and Metabolism, Shanghai Jiao Tong University Affiliated Sixth People's Hospital, Shanghai Clinical Center for Diabetes, Shanghai Diabetes Institute, Shanghai Key Laboratory of Diabetes Mellitus, Shanghai, China.

Mesolimbic opioid-dopamine interaction is disrupted in obesity but recovered by weight loss following bariatric surgery.

Transl Psychiatry 2021 May 1;11(1):259. Epub 2021 May 1.

Turku PET Centre, Turku University Hospital and University of Turku, Turku, Finland.

Obesity is a growing burden to health and the economy worldwide. Obesity is associated with central µ-opioid receptor (MOR) downregulation and disruption of the interaction between MOR and dopamine D receptor (DR) system in the ventral striatum. Weight loss recovers MOR function, but it remains unknown whether it also recovers aberrant opioid-dopamine interaction. Read More

Single nucleotide polymorphism in CD36: Correlation to peptide YY levels in obese and non-obese adults.

Clin Nutr 2021 Mar 6;40(5):2707-2715. Epub 2021 Mar 6.

Molecular Physiology Laboratory, Department of Biochemistry, Bharathiar University, Coimbatore, Tamilnadu, 641046, India. Electronic address:

Background & Aims: Human beings are often driven to exhibit dietary preference according to their hedonic characteristics. Though previous studies proposed that the fat taste preference of an obese individual was associated with BMI, the perception of fat taste differs for every individual. The genetic variation among populations in taste receptor genes such as CD36 may be a contributing factor for this difference. Read More

Clin Nutr 2021 Apr 20;40(5):2602-2608. Epub 2021 Apr 20.

Karolinska Institutet, Department of Clinical Science, Danderyd Hospital & Department of Surgery, Ersta Hospital, 116 91 Stockholm, Sweden. Electronic address:

Background & Aims: Owing to the "obesity-pandemic", an increasing number of individuals are in need of treatment for obesity and obesity-related disorders. For patients with severe disease, results with conventional treatment modalities such as diet regimens, physical activity, and pharmacologic agents most often lack satisfactory efficacy and/or sustainability. In contrast, bariatric surgery has been demonstrated to be associated with marked, long-term weight loss as well as resolution or improvement of co-morbid disease, in particular metabolic aberrations such as insulin resistance and type 2 diabetes.

Weight loss after Roux-En-Y gastric bypass surgery reveals skeletal muscle DNA methylation changes.

Clin Epigenetics 2021 May 1;13(1):100. Epub 2021 May 1.

Department of Medicine, Division of Endocrinology, The University of Arizona College of Medicine, 1501 N. Campbell Ave, PO Box 245035, Tucson, AZ, 85724-5035, USA.

Background: The mechanisms of weight loss and metabolic improvements following bariatric surgery in skeletal muscle are not well known; however, epigenetic modifications are likely to contribute. The aim of our study was to investigate skeletal muscle DNA methylation after weight loss induced by Roux-en-Y gastric bypass (RYGB) surgery. Muscle biopsies were obtained basally from seven insulin-resistant obese (BMI > 40 kg/m) female subjects (45. Read More

Impaired Family Functioning Affects 6-Month and 12-Month Postoperative Weight Loss.

Obes Surg 2021 May 1. Epub 2021 May 1.

Department of Surgery, The Ohio State Wexner Medical Center, Columbus, OH, 43210, USA.

Purpose: Prior cross-sectional research details the high rate of impaired family functioning, a measure of the overall family environment, among adult bariatric surgery patients; however, family functioning has not been explored in relation to adult patient's postoperative outcomes.

Changes in relationship status following bariatric surgery.

Int J Obes (Lond) 2021 Apr 30. Epub 2021 Apr 30.

National Institute of Public Health, University of Southern Denmark, Copenhagen K, Denmark.

Background And Objective: Bariatric surgery is a major event associated with psychological changes such as improvements in self-esteem, increased autonomy, and better self-value. Such changes could affect the patient's interpersonal relationships; however, little is known about the impact of bariatric surgery on changes in relationship status. In this paper, we aim to test the hypothesis that bariatric surgery is associated with changes in interpersonal relationships such as becoming single for those who were in a relationship or entering a relationship among those who were single before surgery.
