AIm：To analyze the in vitro activity of moxifloxacin and piperacillin/sulbactam against pathogens isolated from patients with acute cholangitis. mETHODS： In this prospective study a total of 65 patients with acute cholangitis due to biliary stone obstruction （n = 7）, benign biliary stricture （n = 16）, and malignant biliary stricture （n = 42） were investigated with regard to spectrum of bacterial infection and antibiotic resistance. Pathogens were isolated from bile cultures in all study patients. In 22 febrile patients, blood cultures were also obtained. In vitro activity of moxifloxacin and piperacillin/ sulbactam was determined by agar diffusion. RESULTS： Thirty-one out of 65 patients had positive bile and/or blood cultures. In 31 patients, 63 isolates with 17 different species were identified. The predominant strains were Enterococcus species （26/63）, Ecoli （13/63） and Klebsiella species （8/63）. A comparable in vitro activity of moxifloxacin and piperacillin/sulbactam was observed for *** and Klebsiella species. In contrast, Enterococcus species had higher resistances towards moxifloxacin. Overall bacteria showed antibiotic resistances in vitro of 34.9% for piperacillin/sulbactam and 36.5% for ***： Enterococcus species, ***/i and Klebsiella species were the most common bacteria isolated from bile and/or blood from patients with acute cholangitis. Overall, a mixed infection with several species was observed, and bacteria showed a comparable in vitro activity for piperacillin/sulbactam and moxifloxacin.

Inflammatory bowel disease (IBD) affects women of childbearing age and can influence fertility, pregnancy and decisions regarding breastfeeding. Women with IBD need to consider the possible course of disease during pregnancy, the benefits and risks associated with medications required for disease management during pregnancy and breastfeeding and the effects of mode of delivery on their disease. When indicated, aminosalicylates and thiopurines can be safely used during pregnancy. Infliximab and Adalimumab are considered probably safe during the first two trimesters. During the third trimester the placenta can be crossed and caution should be applied. methotrexate is associated with severe teratogenicity due to its folate antagonism and is strictly contraindicated. Women with IBD tend to deliver earlier than healthy women, but can have a vaginal delivery in most cases. Caesarean sections are generally recommended for women with active perianal disease or after ileo-anal pouch surgery. While the impact of disease activity and medication has been addressed in several studies, there are minimal studies evaluating patients' perspective on these issues. Women's attitudes may influence their decision to have children and can positively or negatively influence the chance of conceiving, and their beliefs regarding therapies may impact on the course of their disease during pregnancy and/or breastfeeding. This review article outlines the impact of IBD and its treatment on pregnancy, and examines the available data on patients' views on this subject.

Inflammasomes are important for maintaining intestinal homeostasis, and dysbiosis contributes to the pathology of inflammatory bowel disease （IBD） and increases the risk for colorectal cancer, Inflammasome defects contribute to chronic intestinal inflammation and increase the susceptibility to colitis in mice, However, the inflammasome sensor absent in melanoma 2 （AIm2） protects against coiorectal cancer in an inflammasome-independent manner through DNA-dependent protein kinase and Akt pathways, Yet, the roles of the AIm2 inflammasome in IBD and the early phases of colorectal cancer remain ill-defined, Here we show that the AIm2 inflammasome has a protective role in the intestine, During steady state, Aim2 deletion results in the loss of IL-18 secretion, suppression of the IL-22 binding protein （IL-22BP） in intestinal epithelial cells and consequent loss of the STAT3-dependent antimicrobial peptides （AmPs） Reg3β and Reg3γ, which promotes dysbiosis-linked colitis, During dextran sulfate sodium-induced colitis, a dysfunctional IL-18/IL-22BP pathway in Aim2^-/- mice promotes excessive IL-22 production and elevated STAT3 activation, Aim2^-/- mice further exhibit sustained STAT3 and Akt activation during the resolution of colitis fueled by enhanced Reg3b and Reg3g expression, This self-perpetuating mechanism promotes proliferation of intestinal crypt cells and likely contributes to the recently described increase in susceptibility of Aim2^-/- mice to colorectal cancer, Collectively, our results demonstrate a central role for the AIm2 inflammasome in preventing dysbiosis and intestinal inflammation through regulation of the IL-18/IL-22BP/IL-22 and STAT3 pathway and expression of select AmPs.
