Our systematic review and meta-analysis showed that Seprafilm could decrease abdominal adhesions after general surgery, which may benefit patients, but could not reduce postoperative intestinal obstruction. At the same time, Seprafilm did increase abdominal abscesses and anastomotic leaks.

Nonalcoholic fatty liver disease (NAFLD) has been suggested to be a strong risk factor of colorectal benign adenomas and advanced neoplasms. The aim of this large cohort study was to further investigate the prevalence of colorectal malignant neoplasm (CRMN) in patients with NAFLD and determine whether association between NAFLD and CRMN exists. 2,315 community subjects (1,370 males and 945 females) who underwent a routine colonoscopy according to international colorectal cancer screening guideline were recruited. Nature of colorectal lesions determined by biopsy and NAFLD was diagnosed by ultrasound. Binary logistic regression analysis was applied to explore the related associations. Prevalence of CRMN was 29.3% (77/263) in patients with NAFLD, which was significantly higher than 18.0% (369/2,052) in the control group (P<0.05). In addition, malignant neoplasm in NAFLD group occurred more frequently at sigmoid colon than in control group (14.3 vs. 11.9%). The incidence of highly-differentiated colorectal adenocarcinoma in NAFLD group was significantly higher than control group (62.3 vs. 9.8%). Univariate analysis showed that NAFLD had strong association with CRMN (OR 2.043; 95% CI 1.512-2.761; P<0.05). After adjusting for metabolic and other confounding factors, NAFLD remained as an independent risk factor for CRMN (OR 1.868; 95% CI 1.360-2.567; P<0.05). NAFLD was an independent risk factor for CRMN. Sigmoid carcinoma and highly differentiated colorectal adenocarcinoma were more commonly found in NAFLD.

TIPS is currently the first choice to prevent rebleeding except that TIPS is worse than endoscopic therapy for encephalopathy. An exploration of new approaches out of above complications will be of considerable clinical significance and be a challenge to clinicians.

Objective: Intake of n-3 polyunsaturated fatty acids (n-3 PUFAs) may protect against mild cognitive impairment (MCI). However, there is still a lack of the n-3 PUFAs intervention in the elderly with MCI in China. The aim of the present study was to investigate the effect of n-3 PUFA supplementation on cognitive function in the Chinese elderly with MCI. Methods: Eighty six MCI individuals aged 60 years or older were randomly assigned to receive either n-3 PUFAs (480 mg DHA and 720 mg EPA per day, n = 44) or placebo (olive oil, n = 42) capsules. The changes of cognitive functions were assessed using Basic Cognitive Aptitude Tests (BCAT). Results: The mean age of participants was 71 years old, and 59% of the participants were men. n-3 PUFA supplementation was associated with improved total BCAT scores, perceptual speed, space imagery efficiency, and working memory (p < 0.01), but not with mental arithmetic efficiency or recognition memory (p > 0.05). Subgroup analysis by sex showed that n-3 PUFAs significantly improved perceptual speed (p = 0.001), space imagery efficiency (p = 0.013), working memory (p = 0.018), and total BCAT scores (p = 0.000) in males. However, in females, the significant beneficial effects can only be observed in perceptual speed (p = 0.027), space imagery efficiency (p = 0.006), and total BCAT scores (p = 0.015)—not working memory (p = 0.113). Conclusion: n-3 PUFAs can improve cognitive function in people with MCI. Further studies with different fish oil dosages, longer intervention periods, and larger sample sizes should be investigated before definite recommendations can be made.
