Background/Aims: Hybrid endoscopic submucosal dissection (ESD), in which an incision is made around a lesion and snaring is per-formed after submucosal dissection, has some advantages in colorectal surgery, including shorter procedure time and preventing per-foration. However, its value for rescue resection in difficult colorectal ESD cases remains unclear. This study evaluated the utility of res-cue hybrid ESD (RH-ESD). Methods: We divided 364 colorectal ESD procedures into the conventional ESD group (C-ESD, n=260), scheduled hybrid ESD group(SH-ESD, n=69), and RH-ESD group (n=35) and compared their clinical outcomes. Results: Resection time was significantly shorter in the following order: RH-ESD (149 [90–197] minutes) >C-ESD (90 [60–140] min-utes) >SH-ESD (52 [29–80] minutes). The en bloc resection rate increased significantly in the following order: RH-ESD (48.6%), SH-ESD (78.3%), and C-ESD (97.7%). An analysis of factors related to piecemeal resection of RH-ESD revealed that the submucosal dis-section rate was significantly lower in the piecemeal resection group (25% [20%–30%]) than in the en bloc resection group (40% [20%–60%]). Conclusions: RH-ESD was ineffective in terms of curative resection because of the low en bloc resection rate, but was useful for avoid-ing surgery.

Fecal incontinence (FI) has a significant long-term impact on patient quality of life for which there is a range of medical and surgical management alternatives. We report the preliminary outcome using the ForConti Contix Faecal Incontinence Management System (FIMS) in FI patients who had failed conservative therapy and who were recruited at 2 tertiary institutions between September 2018 and September 2020. Comparative assessments were made before and after 2 week periods of treatment using bowel diaries and subjective Wexner and Faecal Incontinence Quality of Life scores. Of 17 patients enrolled, 11 completed an 8-week assessment with a significant fall in the average percentage of FI days reported from 84% before treatment to 16.8% at the first posttreatment assessment and down to 13.2% by the second assessment period. This finding correlated with a similar reduction in the total weekly number of episodes of frank FI, minor soiling, and fecal urgency reported by patients along with concomitant improvements in the Wexner scores. For those using the device, there was less concern about accidental bowel leakage, high rates of satisfaction, and minimal problems with the device. Initial results are encouraging warranting further study.
Nutrient-Based Appetite Regulation

Regulation of appetite is dependent on crosstalk between the gut and the brain, which is a pathway described as the gut-brain axis (GBA). Three primary appetite-regulating hormones that are secreted in the gut as a response to eating a meal are glucagon-like peptide 1 (GLP-1), cholecystokinin (CCK), and peptide YY (PYY). When these hormones are secreted, the GBA responds to reduce appetite. However, secretion of these hormones and the response of the GBA can vary depending on the types of nutrients consumed. This narrative review describes how the gut secretes GLP-1, CCK, and PYY in response to proteins, carbohydrates, and fats. In addition, the GBA response based on the quality of the meal is described in the context of which meal types produce greater appetite suppression. Last, the beneficiary role of exercise as a mediator of appetite regulation is highlighted.

PURPOSE. The aim of the present study was to evaluate if a smaller morse taper abutment has a negative effect on the fracture resistance of implant-abutment connections under oblique compressive loads compared to a conventional abutment. MATERIALS AND METHODS. Twenty morse taper conventional abutments (4.8 mm diameter) and smaller abutments (3.8 mm diameter) were tightened (20 Ncm) to their respective implants (3.5 * 11 mm) and after a 10 minute interval, implant/abutment assemblies were subjected to static compressive test, performed in a universal test machine with 1 mm/min displacement, at 45 degree inclination. The maximum deformation force was determined. Data were statistically analyzed by student t test. RESULTS. Maximum deformation force of 4.8 mm and 3.8 mm abutments was approximately 95.33 kgf and 95.25 kgf, respectively, but no fractures were noted after mechanical test. Statistical analysis demonstrated that the evaluated abutments were statistically similar (P=.230). CONCLUSION. Abutment measuring 3.8 mm in diameter (reduced) presented mechanical properties similar to 4.8 mm (conventional) abutments, enabling its clinical use as indicated.

A new epimerization mechanism was introduced for the polymerization of propylene obtained by octahedral benzamidinate complexes. Deuterium labeling showed that deuterium is transferred from a methyne to a methylene position in the polymer inducing a stereoerror and an elastic material. In addition, two active species are formed during the polymerization of propylene promoted by the octahedral bis(benzamidinate) titanium dialkyl complexes.
