Abstract
BACKGROUND & AIMS Whether preoperative treatment of inflammatory bowel disease (IBD) with tumor necrosis factor inhibitors (TNFis) increases the risk of postoperative infectious complications remains controversial. The primary aim of this study was to determine whether preoperative exposure to TNFis is an independent risk factor for postoperative infectious complications within 30 days of surgery. METHODS We conducted a multicenter prospective observational study of patients with IBD undergoing intra-abdominal surgery across 17 sites from the Crohn's & Colitis Foundation Clinical Research Alliance. Infectious complications were categorized as surgical site infections (SSIs) or non-SSIs. Current TNFi exposure was defined as use within 12 weeks of surgery, and serum was collected for drug-level analyses. Multivariable models for occurrence of the primary outcome, any infection, or SSI were adjusted by predefined covariates (age, sex, preoperative steroid use, and disease type), baseline variables significantly associated (P < .05) with any infection or SSI separately, and TNFi exposure status. Exploratory models used TNFi exposure based on serum drug concentration. RESULTS A total of 947 patients were enrolled from September 2014 through June 2017. Current TNFi exposure was reported by 382 patients. Any infection (18.1% vs 20.2%, P = .469) and SSI (12.0% vs 12.6%, P = .889) rates were similar in patients currently exposed to TNFis and those unexposed. In multivariable analysis, current TNFi exposure was not associated with any infection (odds ratio, 1.050; 95% confidence interval, 0.716-1.535) or SSI (odds ratio, 1.249; 95% confidence interval, 0.793-1.960). Detectable TNFi drug concentration was not associated with any infection or SSI. CONCLUSIONS Preoperative TNFi exposure was not associated with postoperative infectious complications in a large prospective multicenter cohort.

Abstract
BACKGROUND Pouchitis can be a chronic complication of ileal pouch-anal anastomosis. We aimed to determine the efficacy and safety of hyperbaric oxygen therapy (HBOT) for chronic antibiotic-refractory pouchitis (CARP) and other inflammatory conditions of the pouch. METHODS This was a retrospective case series of adults with inflammatory bowel disease (IBD) who underwent ileal pouch-anal anastomosis and then developed CARP and received HBOT between January 2015 and October 2019. A modified Pouchitis Disease Activity Index (mPDAI) score was used to quantify subjective symptoms (0-6) and endoscopic findings (0-6) before and after HBOT. RESULTS A total of 46 patients were included, with 23 (50.0%) being males with a mean age of 43.6 ± 12.9 years. The median number of HBOT sessions was 30 (range 10-60). There was a significant reduction in the mean mPDAI symptom subscore from 3.19 to 1.91 after HBOT (P < 0.05). The pre- and post-HBOT mean mPDAI endoscopy subscores for the afferent limb were 2.31 ± 1.84 and 0.85 ± 1.28 (P = 0.006); for the pouch body, 2.34 ± 1.37 and 1.29 ± 1.38 (P < 0.001); and for the cuff, 1.93 ± 1.11 and 0.63 ± 1.12 (P < 0.001), respectively. Transient side effects included ear barotrauma in 5 patients (10.9%) and hyperbaric myopic vision changes in 5 patients (10.9%). CONCLUSIONS Despite minor adverse events, HBOT was well tolerated in patients with CARP and significantly improved symptoms and endoscopic parameters.

Abstract
Studies have shown that colorectal cancer (CRC) incidence is equal between men and women. However, several studies have demonstrated lower adenoma detection rates in women than in men. Many questions arise about differences in adenomas, CRC, and screening practices between men and women: should screening be the same for both sexes, are there differences in risk factors in the formation of colon cancer, should special groups of women be screened differently from the general population, are colonoscopies tolerated differently in women and why, and what determines if a woman will undergo colonoscopy? This article reviews these issues.

Abstract
Recombinant nuclear polyhedrosis viruses (NPVs) expressing insect-selective toxins, hormones, or enzymes could enhance their insecticidal properties. We have constructed a recombinant, polyhedrin-positive Autographa californica NPV (AcNPV) that is orally infectious and expresses an insect-selective toxin (AaIT), isolated from the scorpion Androctonus australis, under the control of the p10 promoter. Bioassays with the recombinant baculovirus on 2nd instar larvae of Heliothis virescens demonstrated a significant decrease in the time to kill (LT50 88.0 hours) compared to wild-type AcNPV (LT50 125 hours). Production of AaIT was confirmed by western blot analysis of larval hemolymph from infected H. virescens, and bioassays with larvae of Sarcophaga falculata.
