question:
Surgical site infections (SSIs) after colectomy for colon cancer (CC), Crohn's disease (CD), and diverticulitis (DD) significantly impact both the immediate postoperative course and long-term disease-specific outcomes. We aim to profile the effect of diagnosis on SSI after segmental colectomy using the National Surgical Quality Improvement Program (NSQIP) data set.", "NSQIP data from 2006 to 2011 were investigated, and segmental colectomy procedures performed for the diagnoses of Crohn's disease, DD, and colon malignancy were included. SSI complications were compared by diagnosis using univariate and multivariate analysis.", 'We included 35,557 colectomy cases in the analysis. CD had the highest rate of postoperative SSI (17 vs. 13% DD vs. 10% CC; p\u2009<\u20090.001). Using CC as the comparison group and controlling for multiple variables, the multivariate analysis showed that the CD group had an increased risk for acquiring at least one SSI (odds ratio (OR)\u2009=\u20091.38, p\u2009≤\u20090.001), deep incisional SSI (OR\u2009=\u20091.85, p\u2009=\u20090.03), and organ space SSI (OR\u2009=\u20091.51, p\u2009=\u20090.02).
answer:
Is crohn 's disease but not diverticulitis an independent risk factor for surgical site infections in colectomy?


question:
To describe the epidemiology of acute hand injuries and hand infections and to describe the factors associated with the transfer of these patients to a level 1 trauma center. In addition, we sought to understand management before transfer.', 'Retrospective review of patients with hand trauma or hand infection transferred to our level 1 trauma center from May 2009 to August 2011. We also identified hospitals with emergency departments (EDs) in our region and surveyed ED providers in these hospitals with regard to acute hand care.', 'A level 1 trauma center in the United States.', 'Four hundred sixty consecutive transfers for acute hand care.', 'The average patient age was 38. Most were male (84%), uninsured (51%), and from another county (59%). The average distance of transfer was 51 miles, and 80% were transferred by ground ambulance. The most common reasons for transfer were amputations (24%), infections (21%), lacerations (17%), and fractures/dislocations (16%). Of the 345 hospitals with an ED surveyed, 71% never had hand surgery coverage.
answer:
Do lack of Acute Hand Care in the Southwest United States?


question:
Pichia stipitis xylose reductase (Ps-XR) has been used to design Saccharomyces cerevisiae strains that are able to ferment xylose. One example is the industrial S. cerevisiae xylose-consuming strain TMB3400, which was constructed by expression of P. stipitis xylose reductase and xylitol dehydrogenase and overexpression of endogenous xylulose kinase in the industrial S. cerevisiae strain USM21.', 'In this study, we demonstrate that strain TMB3400 not only converts xylose, but also displays higher tolerance to lignocellulosic hydrolysate during anaerobic batch fermentation as well as 3 times higher in vitro HMF and furfural reduction activity than the control strain USM21. Using laboratory strains producing various levels of Ps-XR, we confirm that Ps-XR is able to reduce HMF both in vitro and in vivo. Ps-XR overexpression increases the in vivo HMF conversion rate by approximately 20%, thereby improving yeast tolerance towards HMF. Further purification of Ps-XR shows that HMF is a substrate inhibitor of the enzyme.
answer:

Does pichia stipitis xylose reductase help detoxifying lignocellulosic hydrolysate by reducing 5-hydroxymethyl-furfural ( HMF )?
