Reflections About the Gut, A Microbiologist’s Perspective by Bernard AM Van der Zeijst in
Current Trends in Gastroenterology and Hepatology in Lupine Publishers

Without doubt, the original function of the human gut was to digest and absorb food. Its epithelial cells absorb food after it has been processed to smaller components by enzymatic digestion. Comparable epithelial processes are also found in animals, including sea animals, and plants [1]. Disturbance of the gut homeostasis by infections leads to disease. From mild diarrhea of short duration (e.g. caused by poliovirus, rotavirus, norovirus and Campylobacter) to lethal infections by toxin producing bacteria such as cholera. Cholera often occurs as a result of crowding and poor hygiene. It was very problematic during the first industrial revolution in the UK where poor migrants lived under dismal conditions.

The Use of Sodium-Glucose Cotransporter 2 Inhibitors in Non-Alcoholic Fatty Liver Disease

  Opinion Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of progressive liver abnormalities from simple hepatic steatosis to non-alcoholic steatohepatitis (NASH) to advanced fibrosis, cirrhosis, and/or hepatocellular carcinoma [1]. Parallel to the rising burden of obesity and metabolic syndrome, NAFLD has emerged as the leading cause of chronic liver disease at an estimated global prevalence of 24% [2]. Besides its known clinical burden for liver-related morbidity and mortality, NAFLD is potentially linked with other extra-hepatic chronic diseases and may be considered a multisystem condition. Particularly, NAFLD increases the risk of type 2 diabetes, cardiovascular diseases, chronic kidney disease, and all-cause mortality [1]. Potential pathophysiologic mechanisms underlying the detrimental effects of NAFLD include hyperglycemia, systemic inflammation, and increased oxidative stress [3]. Sodiumglucose cotransporter 2 (SGLT2) inhibitors are a new class of anti

Acute Upper Gastrointestinal Bleeding (UGIB) In A Resource Limited Setting Highly Endemic for Viral Hepatitis B: Which Etiologies for Which Real Clinical Practices?

  Abstract Aim : To determine the aetiologies of acute upper gastrointestinal bleeding (UGIB) in a setting highly endemic for hepatitis B and to describe actual clinical practices in a resource-limited setting. Patients and methods: This study was conducted in two parts. The first part was retrospective from January 1st 2010, to December 31st 2019 on the epidemiological profile of UGIB and the second was a prospective study from December 1st 2017 to May 31st 2018 to evaluate, in a blinded experiment, the actual clinical practices in front of an acute UGIB at the emergency units in Yaounde (Cameroon), and included: recognizing UGIB, assessing for severity, taking emergency measures and prescribing emergency Eosogastroduodenal endoscopy (EGDE). Results : During the retrospective period, 506 patients (prevalence of acute UGIB in the services 5.6%) were included of which 71.3% were men (sex ratio 2.5). The mean age was 49.9 +/- 8 years. Haematemesis was inaugural in 350 pa

Food Sources and Bioavailability of Calcium

  Abstract The identification of the calcium ration by self-questionnaires validated in the region of Blida and the Wilayas of approximately is one of the rare studies in Algeria. She was interested in a part of the Algerian population with characteristics that do not seem very different from the general population; however, this dietary survey must be supplemented by a study on a representative sample of the general population. The study showed insufficient calcium intake mainly secondary to low consumption of milk and dairy products. This low calcium intake was objectified by the two questioning methods (Fardellone and CERIN), however, it will be desirable to establish Algerian self-questionnaires validated and verified by our learned society. The results obtained are worrying, which obliges us to immediately introduce a prevention and control strategy against the multiple pathologies linked to this low calcium intake, the main one being osteoporosis with its seriou
