Inflammatory bowel disease patients are prone to immunosuppression due to effects of their medications. Physicians are recommended to assess vaccination status and overall health in all patients, prior to initiation of immunosuppressive therapy. Immunosuppressant medications in women with inflammatory bowel disease are often continued during pregnancy, which can result in newborns having an increased risk of immunosuppression at birth. While medication-induced immunosuppression in infants is transient, parents should be counselled about delaying live vaccine administration in newborns until they are immune competent. A retrospective study was done over six months at an urban multispecialty medical center to assess whether physicians are counselling pregnant immunosuppressed inflammatory bowel disease patients regarding live vaccinations in their newborns. The study revealed that only 57% of patients had documented counselling in their charts. Further studies are necessary to determine physician counselling practices of pregnant women about live vaccines. It is critical that physicians and patients are aware of the risks of immunosuppression in pregnancy and the potential impact of live vaccinesupon the newborn.

CO2 separation performance in facilitated transport membranes has been reported depended not only on the CO2 carrier properties but also to a great extent on the polymeric matrix regarding the capacity of retaining water and carriers as well as the processability for coating defect-free ultra-thin films. In this study, the blends of hydrophilic polymers polyvinyl pyrrolidone(PVP) and polyvinyl alcohol(PVA) were studied to find an optimal polymer matrix to host carriers in facilitated transport membranes for enhanced CO2 separation. It is found out that the optimized blend is 50/50 PVA/PVP by weight, which shows a significant increase in the water uptake(from 63 to 84%) at equilibrium state compared to the neat PVA. Polyethyleneimine(PEI) was employed to provide sample carriers to evaluate the synergistic effect of PVA and PVP on the CO2 separation performance. A thin film composite(TFC) membrane of the optimized blend(50/50 PVA/PVP with 50 wt% PEI) was fabricated on polysulfone(PSf) porous support. The fabrication of the TFC membranes is simple and low cost, and CO2 permeance of the optimized blend membrane is nearly doubled with the CO2/N2 selectivity remained unchanged, showing great potential for industrial applications of the resulted membranes.

AIM To examine the evidence about psychiatric morbidity after inflammatory bowel disease(IBD)-related surgery. METHODS PRISMA guidelines were followed and a protocol was published at PROSPERO(CRD42016037600). Inclusion criteria were studies describing patients with inflammatory bowel disease undergoing surgery and their risk of developing psychiatric disorder. RESULTS Twelve studies(including 4340 patients) were eligible. All studies were non-randomized and most had high risk of bias. Patients operated for inflammatory bowel disease had an increased risk of developing depression,compared with surgical patients with diverticulitis or inguinal hernia,but not cancer. In addition,patients with Crohn's disease had higher risk of depression after surgery compared with non-surgical patients. Patients with ulcerative colitis had higher risk of anxiety after surgery compared with surgical colorectal cancer patients. Charlson comorbidity score more than three and female gender were independent predictors for depression and anxiety following surgery. CONCLUSION The review cannot give any clear answer to the risks of psychiatric morbidity after surgery for IBD studies with the lowest risk of bias indicated an increased risk of depression among surgical patients with Crohn's disease and increased risk of anxiety among patients with ulcerative colitis.

Fruit and leaf shoot of litchi （Litchi chinensis） infestation by naturally occurring populations of the fruit bprer, Conopomorpha sinensis larvae and C. sinensis parasitization rates were determined in litchi orchards in northern Thailand at high （ca. 1 400 m ASL） and low （ca. 800 m ASL） elevations with different, non-overlapping fruiting seasons. In addition, spray applications of Bacillus thuringiensis var. aizawai, the natural compound spinosad and the chemical pesticide imidacloprid were conducted in the field to test the effects of these agents on C. sinensis fruit infestation rate. Fruit infestation rate and fruit growth, studied in a low elevation orchard, were sigmoidal and showed a highly significant positive correlation （P ≤ 0.01）. Leaf shoot infestation rate in the low elevation orchard decreased in the course of the fruiting season （March until May）, but increased in the high elevation orchard, where no fruits were present within the same period of time. Together, these results indicate that females of C. sinensis clearly prefer fruits over shoots for oviposition. If no fruits are available, which was the case in the high elevation orchard during that time, they are constrained to lay their eggs on shoots. The parasitization rate of C. sinensis larvae in untreated fruits was 54.3%. The parasitoid species were Chelonus chailini （90.8%） and Phanerotoma sp. （9.2%）. In the leaf shoots, C. sinensis was found to be parasitized by Phanerotoma sp. and Apanteles briareus. The applications of the different active agents had no significant effect on C. sinensis fruit infestation compared to the untreated control. Besides the cryptic life of the larvae, this is most probably explained by the fact that C. sinensis has several generations during the fruiting season. Because of the high parasitization rates recorded, an alternative and more effective control measure than the application of pesticides might be the augmentative release of parasitoids.
