Pharmacological treatment of obesity

Rev Med Inst Mex Seguro Soc 2018 11 30;56(4):395-409. Epub 2018 Nov 30.

Instituto Mexicano del Seguro Social, Hospital de Especialidades “Dr. Bernardo Sepúlveda Gutiérrez”, Unidad de Investigación Médica en Endocrinología Experimental. Ciudad de México, México

More than 70% of the population in Mexico is overweight or obese, affecting mainly people in productive age. Obesity is associated with the development of diseases that increase cardiovascular risk (diabetes mellitus, hypertension or atherogenic dyslipidemia), diseases that limit the quality of life of the patient (osteoarthrosis or sleep apnea) and even with the increase in the incidence of certain types of cancer (breast or colon). It is evident that the decrease of at least 5% of body weight induces improvement in all these factors; however, in some patients it is difficult to achieve this goal only with lifestyle modifications.

Eosinophil Counts in Mucosal Biopsies of the Ileum and Colon: Interobserver Variance Affects Diagnostic Accuracy.

Patholog Res Int 2018 4;2018:2638258. Epub 2018 Nov 4.

Department of Gastroenterology and Hepatology, University Medical Center Brandenburg, Brandenburg, Germany.

Primary eosinophilic gastroenteritis and colitis (EGE) is a rare entity with unspecific clinical and endoscopic findings. Validated histopathologic criteria for confirming the diagnosis are lacking, because numeric values for normal or elevated concentrations of eosinophils in mucosal biopsies are varying between observers. To quantify this interobserver variance, we had the same set of 30 slides of eosinophilic-rich mucosal biopsies from the ileum and colon systematically reviewed by a panel of six independent pathologists, each with more than a ten-year experience in the field.

Robustness of the non-neuronal cholinergic system in rat large intestine against luminal challenges.

Pflugers Arch 2018 Dec 1. Epub 2018 Dec 1.

Institute for Veterinary Physiology and Biochemistry, Justus Liebig University Giessen, Giessen, Germany.

Acetylcholine and atypical esters of choline such as propionyl- and butyrylcholine are produced by the colonic epithelium and are released when epithelial receptors for short-chain fatty acids (SCFA) are stimulated by propionate. It is assumed that the SCFA used by the choline acetyltransferase (ChAT), the central enzyme for the production of these choline esters, originate from the colonic lumen, where they are synthesized during the bacterial fermentation of carbohydrates. Therefore, it seemed to be of interest to study whether the non-neuronal cholinergic system in the colonic epithelium is affected by maneuvers intended to stimulate or to inhibit colonic fermentation by changing the intestinal microbiota.

 Colon interposition for benign strictures is associated with significant perioperative complications that carry high morbidity and mortality. Although rarely reported in the literature, adenocarcinoma can occur as a late complication in an interposed colonic segment. We report a case of a late-stage adenocarcinoma in a colonic interposition performed for benign esophageal stricture. Read More

A scalable solution for tumor mutational burden from formalin-fixed, paraffin-embedded samples using the Oncomine Tumor Mutation Load Assay.

Transl Lung Cancer Res 2018 Dec;7(6):616-630

Thermo Fisher Scientific, Waltham, Massachusetts, USA.

Background: Tumor mutational burden (TMB) is an increasingly important biomarker for immune checkpoint inhibitors. Recent publications have described strong association between high TMB and objective response to mono- and combination immunotherapies in several cancer types. Existing methods to estimate TMB require large amount of input DNA, which may not always be available. Read More

Metastatic inflammatory myofibroblastic tumor of the bladder.

Urol Case Rep 2019 Mar 15;23:10-12. Epub 2018 Nov 15.

Department of Surgery - Division of Urology, 1 Hospital Drive, MC 301E, Columbia, MO, 65212, USA.

A 61-year-old male presented with gross hematuria and transurethral resection of bladder tumor revealed inflammatory myofibroblastic tumor (IMT). Due to extent of disease leading to ureteral obstruction and hydronephrosis, radical cystectomy (RC) with ileal conduit urinary diversion was performed. Five months after RC, the patient presented with decreased urine output. Read More

Morbidity and mortality of synchronous hepatectomy with cytoreductive surgery/hyperthermic intraperitoneal chemotherapy (CRS/HIPEC).

J Gastrointest Oncol 2018 Oct;9(5):828-832

Department of Surgery, University of Kansas Medical Center, Kansas City, KS, USA.

Background: Liver resection in conjunction with partial colectomy for colon cancer is considered acceptable treatment for isolated metastasis to the liver. This method is unstudied in patients undergoing cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for carcinomatosis due to colon cancer and high grade appendiceal cancer.

Methods: A retrospective chart review included patients from 2005 to 2016 undergoing CRS/HIPEC. Read More

Differences in overall survival and mutation prevalence between right- and left-sided colorectal adenocarcinoma.

J Gastrointest Oncol 2018 Oct;9(5):778-784

Medical Oncology, Cancer Treatment Centers of America, Philadelphia, PA, USA.

Background: Prior reports have demonstrated inferior outcomes for patients with right-sided colorectal cancer (CRC) compared to patients with left-sided disease, as well as differences in treatment response based on disease sidedness. Differences in prognosis remain even among patients with metastatic disease, indicating that anatomy or stage at diagnosis alone cannot explain all of these findings. While genetic differences between right- and left-sided CRC have long been described, the genetic and molecular drivers underlying differences in prognosis and treatment response remain incompletely understood.

Cobalamin (Vitamin B12) Induced a Shift in Microbial Composition and Metabolic Activity in an Colon Simulation.

Front Microbiol 2018 16;9:2780. Epub 2018 Nov 16.

School of Food Science and Biotechnology, Zhejiang Gongshang University, Hangzhou, China.

Cobalamin deficiency is believed to be related to disturbances in cell division, neuropathy, nervous system disease and pernicious anemia. Elderly people are usually advised to supplement their diets with cobalamin. As cobalamin has several forms, the effects of different forms of cobalamin on gut microbiota were investigated in this study. Read More
