Lactobacillus plantarum Shinshu N-07 isolated from fermented Brassica rapa L. attenuates visceral fat accumulation induced by high-fat diet in mice.

Lactobacillus plantarum Shinshu N-07 (N07) and Lactobacillus curvatus #4G2 (#4G2) were isolated from fermented Brassica rapa L. and selected as promising probiotics with anti-adiposity activities based on in vitro assays. The anti-adiposity effects of these two strains were investigated using a diet-induced obesity animal model. Epididymal adipose tissue weight and adipocyte area were significantly lower and serum triglycerides and glucose tended to be lower in mice fed the high-fat diet supplemented with N07 compared with those fed the unsupplemented high-fat diet. Strain N07 suppressed hepatic steatosis, with accompanying downregulation of lipogenic genes in the liver. Expression of inflammatory cytokines and macrophage infiltration markers tended to be suppressed by N07 supplementation. Upregulation of uncoupling protein-1 in epididymal adipose tissue by N07 suggested that the transformation of white adipose tissue to brown might have been induced. Intestinal microbiota analysis revealed that a decrease in abundance of family S24-7 (phylum Bacteroidetes) following ingestion of the high-fat diet was partly recovered by supplementation with N07. Changes in those parameters were not observed in mice fed the high-fat diet supplemented with strain #4G2, suggesting strain specificities. Thus, N07 is a potential probiotic strain that could be used to develop functional foods that attenuate visceral fat accumulation after an appropriate human intervention trial.

Robotic ventral mesh rectopexy for rectal prolapse: a single-institution experience.

BACKGROUND: Robotic ventral mesh rectopexy (RVMR) is an appealing approach for the treatment of rectal prolapse and other conditions. The aim of this study was to evaluate the outcomes of RVMR for rectal prolapse. METHODS: We performed a retrospective chart review for patients who underwent RVMR for rectal prolapse at our institution between July 2012 and May 2016. Any patient who underwent RVMR during this time frame was included in our analysis. Any cases involving colorectal resection or other rectopexy techniques were excluded. RESULTS: Of the 24 patients who underwent RVMR, 95.8% of patients were female. Median age was 67.5 years old (IQR 51.5-73.3), and 79.2% of patients were American Society of Anesthesiologists class III or IV. Median operative time was 191 min (IQR 164.3-242.5), and median length of stay was 3 days (IQR 2-3). There were no conversions, RVMR-related complications or mortality. Patients were followed for a median of 3.8 (IQR 1.2-15.9) months. Full-thickness recurrence occurred in 3 (12.4%) patients. Rates of fecal incontinence improved after surgery (62.5 vs. 41.5%, respectively) as did constipation (45.8 vs. 33.3%, respectively). No patients reported worsening symptoms postoperatively. Only one (4.2%) patient reported de novo constipation postoperatively. CONCLUSIONS: RVMR is a feasible, safe and effective option for the treatment of rectal prolapse, with low short-term morbidity and mortality. Multicenter and long-term studies are needed to better assess the benefits of this procedure.

Experimental evaluation of mink and Apodemus speciosus in the Echinococcus multilocularis life-cycle in Hokkaido, Japan.

The epizootiological status of mink (Mustela vison) as definitive hosts and Apodemus speciosus as intermediate hosts in the transmission of Echinococcus multilocularis in Hokkaido, Japan, were evaluated by orally inoculating mink with protoscoleces, and A. speciosus with eggs of the cestode, respectively. No tapeworms were recovered from the alimentary tract of the mink, and no hydatid cysts were recovered from the viscera of the egg-inoculated A. speciosus. We conclude that mink and A. speciosus cannot serve as definitive hosts and intermediate hosts of E. multilocularis, respectively, in Hokkaido.
