Regulation of the gut barrier by carbohydrates from diet - Underlying mechanisms and possible clinical implications.

Int J Med Microbiol 2021 Mar 26;311(4):151499. Epub 2021 Mar 26.

Nstitute of Nutritional Medicine, University of Hohenheim, Stuttgart, Germany. Electronic address:

The gut barrier has been recognized as being of relevance in the pathogenesis of multiple different diseases ranging from inflammatory bowel disease, irritable bowel syndrome, inflammatory joint disease, fatty liver disease, and cardiometabolic disorders. The regulation of the gut barrier is, however, poorly understood. Especially, the role of food components such as sugars and complex carbohydrates has been discussed controversially in this respect.

Hyperregenerative macrocytic anaemia: the role of copper and zinc.

BMJ Case Rep 2021 Apr 14;14(4). Epub 2021 Apr 14.

Internal Medicine, Hospital Uster, Uster, Switzerland.

In a patient with a history of bariatric surgery, severe copper deficiency presenting with macrocytic hyperregenerative anaemia was diagnosed. Besides the impaired intestinal absorption due to a short bowel syndrome, the enteral zinc supplementation competitively decreased the intestinal copper uptake. Once the zinc supplementation was stopped, enteral copper replacement ensued and normalised haemoglobin levels with decreasing median corpuscular volume were observed during follow-up visits.

Activation of KCNQ (K7) K channels in enteric neurons inhibits epithelial Cl secretion in mouse distal colon.

Am J Physiol Cell Physiol 2021 Apr 14. Epub 2021 Apr 14.

Department of Biochemistry, West Virginia University School of Medicine, Morgantown, West Virginia; Department of Medicine, West Virginia University School of Medicine, Morgantown, West Virginia, United States.

K7 (KCNQ) K channels are expressed in many neuronal populations, and play an important role in regulating membrane potential by generating a hyper-polarizing K current and decreasing cell excitability. However, the role of K7 channels in the neural regulation of intestinal epithelial Cl secretion is not known. Cl secretion in mouse distal colon was measured as a function of short circuit current (I), while pharmacological approaches were used to test the hypothesis that activation of K7 channels in enteric neurons would inhibit epithelial Cl secretion.

Alterations in fecal short chain fatty acids (SCFAs) and branched short-chain fatty acids (BCFAs) in men with benign prostatic hyperplasia (BPH) and metabolic syndrome (MetS).

Aging (Albany NY) 2021 Apr 13;13. Epub 2021 Apr 13.

Department of Histology and Development Biology, Pomeranian Medical University in Szczecin, Szczecin 71-210, Poland.

Gut microbiome-derived short-chain fatty acids (SCFAs) emerge in the process of fermentation of polysaccharides that resist digestion (dietary fiber, resistant starch). SCFAs have a very high immunomodulatory potential and ensure local homeostasis of the intestinal epithelium, which helps maintain the intestinal barrier. We analyzed the association between stool SCFAs levels acetic acid (C 2:0), propionic acid (C 3:0), isobutyric acid (C 4:0i), butyric acid (C 4:0n), isovaleric acid (C 5:0i) valeric acid (C 5:0n), isocaproic acid (C 6:0i), and caproic acid (C 6:0n)) in aging man with benign prostatic hyperplasia (BPH) and healthy controls.

Clin Transl Gastroenterol 2021 Apr 12;12(4):e00329. Epub 2021 Apr 12.

Clinical Enteric Neuroscience Translational and Epidemiological Research (CENTER), Mayo Clinic, Rochester, Minnesota, USA.
