Introduction. To determine the effect of fecal microbiota transplantation (FMT) on quality of life (QoL) in patients with inflammatory bowel disease (IBD). Methods. Fourteen IBD patients, including 11 Ulcerative colitis (UC) and 3 Crohn's disease (CD), were treated with FMT via colonoscopy or nasojejunal tube infusion. QoL was measured by IBD Questionnaire (IBDQ). Disease activity and IBDQ were evaluated at enrollment and four weeks after treatment. Patients' attitude concerning the treatment was also investigated. Results. One patient was excluded due to intolerance. All the other patients finished the study well. Mean Mayo score in UC patients decreased significantly (5.80 ± 1.87 versus 1.50 ± 1.35, P < 0.01). Mean IBDQ scores of both UC and CD patients increased (135.50 ± 27.18 versus 177.30 ± 20.88, P = 0.00063, and 107.33 ± 9.45 versus 149.00 ± 20.07, P = 0.024) four weeks after fecal microbiota transplantation. There was no correlation between the IBDQ score and Mayo score before and after FMT. Patients refused to take FMT as treatment repeatedly in a short time. Conlusions. Fecal microbiota transplantation improves quality of life significantly in patients with inflammatory bowel disease.

Initial PD group had lower rate of post-drainage complications and ultimate stoma creation compared to the initial surgery group. Although subsequent surgery may not be avoided after PD, it can provide safe anastomosis for resections. Long-term follow-up should be done to assess the outcome of PD.

IMPORTANCEThe effect of and optimal timing for initiating supplemental parenteral nutrition (SPN) remain unclear after major abdominal surgery for patients in whom energy targets cannot be met by enteral nutrition (EN) alone.OBJECTIVE To examine the effect of early supplemental parenteral nutrition (E-SPN) (day 3 after surgery) or late supplemental parenteral nutrition (L-SPN) (day 8 after surgery) on the incidence of nosocomial infections in patients undergoing major abdominal surgery who are at high nutritional risk and have poor tolerance to EN. DESIGN, SETTING, AND PARTICIPANTSA multicenter randomized clinical trial was conducted from April 1, 2017, to December 31, 2018, in the general surgery department of 11 tertiary hospitals in China. Participants were those undergoing major abdominal surgery with high nutritional risk and poor tolerance to EN (Յ30% of energy targets from EN on postoperative day 2, calculated as 25 and 30 kcal/kg of ideal body weight daily for women and men, respectively) and an expected postoperative hospital stay longer than 7 days. Data analysis was performed from February 1 to October 31, 2020.INTERVENTIONS Random allocation to E-SPN (starting on day 3 after surgery) or L-SPN (starting on day 8 after surgery). MAIN OUTCOMES AND MEASURESThe primary outcome was the incidence of nosocomial infections between postoperative day 3 and hospital discharge.RESULTS A total of 230 patients (mean [SD] age, 60.1 [11.2] years; 140 men [61.1%]; all patients were of Han race and Asian ethnicity) were randomized (115 to the E-SPN group and 115 to the L-SPN group). One patient in the L-SPN group withdrew informed consent before the intervention. The E-SPN group received more mean (SD) energy delivery between days 3 and 7 compared with the L-SPN group (26.5 [7.4] vs 15.1 [4.8] kcal/kg daily; P < .001). The E-SPN group had significantly fewer nosocomial infections compared with the L-SPN group (10/115 [8.7%] vs 21/114 [18.4%]; risk difference, 9.7%; 95% CI, 0.9%-18.5%; P = .04). No significant differences were found between the E-SPN group and the L-SPN group in the mean (SD) number of noninfectious complications (31/115 [27.0%] vs 38/114 [33.3%]; risk difference, 6.4%; 95% CI, −5.5% to 18.2%; P = .32), total adverse events (75/115 [65.2%] vs 82/114 [71.9%]; risk difference, 6.7%; 95% CI, −5.3% to 18.7%; P = .32), and rates of other secondary outcomes. A significant difference was found in the mean (SD) number of therapeutic antibiotic days between the E-SPN group and the L-SPN group (6.0 [0.8] vs 7.0 [1.1] days; mean difference, 1.0 days; 95% CI, 0.2-1.9 days; P = .01). CONCLUSION AND RELEVANCEIn this randomized clinical trial, E-SPN was associated with reduced nosocomial infections in patients undergoing abdominal surgery and seems to be a favorable strategy for patients with high nutritional risk and poor tolerance to EN after major abdominal surgery.

Early enteral nutrition did not increase IAP. In contrast, it might prevent the development of IAH. In addition, EEN might be not appropriate during the initial 3-4 days of SAP onset. Moreover, EN might be of benefit to patients with an IAP <15 mmHg. Early enteral nutrition could improve disease severity and clinical outcome, but did not decrease mortality of SAP.

The contribution of forest generalists and specialists to the dispersal pattern of tree species is not well understood. Specialists are considered low-quality dispersers because their dispersal distance is often short. However, disregard for seed deposition site may result in underestimation of the dispersal quality of specialists. The present study estimated the contribution of generalist and specialist species to the dispersal patterns of the endangered Chinese yew (Taxus chinensis) in a subtropical patchy forest in Southeast China. A relatively diverse assemblage of frugivorous birds visited T. chinensis source trees, and specialist Hypsipetes leucocephalus and generalist Urocissa erythrorhyncha were by far the highest-quantity dispersers. Considering dispersal effectiveness, the quantity aspect of effectiveness differed between the specialist assemblage and generalist assemblage; the contribution of specialists to the quantity part of effectiveness was significantly higher than that of generalists despite the relatively low diversity of specialists. After foraging, both specialist H. leucocephalus and generalist U. erythrorhyncha significantly contributed to the number of seedlings, and their contributions to seedling recruitment did not differ with regard to quality. Our results highlight the ability of T. chinensis to recruit an effective disperser assemblage in patchy habitats, thus increasing its persistence in this disturbed habitat.

Background. The pathogenesis of postoperative ileus (POI) is complex. The present study was designed to investigate the effects of peritoneal air exposure on the POI intestinal inflammation and the underlying mechanism. Methods. Sprague-Dawley rats were randomized into five groups (6/group): the control group, the sham group, and three exposure groups with peritoneal air exposure for 1, 2, or 3 h. At 24 h after surgery, we analyzed the gastrointestinal transit, the serum levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-10, the myeloperoxidase activity, and the levels of TNF-α, IL-1β, IL-6, and IL-10 in the ileum and colon. The oxidant and antioxidant levels in the ileum and colon were analyzed by measuring malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and total antioxidant capacity (T-AOC). Results. Peritoneal air exposure caused an air-exposure-time-dependent decrease in the gastrointestinal transit. The length of peritoneal air exposure is correlated with the severity of both systemic and intestinal inflammations and the increases in the levels of MDA, SOD, GSH-Px, and T-AOC. Conclusions. The length of peritoneal air exposure is proportional to the degree of intestinal paralysis and the severity of intestinal inflammation, which is linked to the oxidative stress response.
