1Operative complications and economic outcomes of cholecystectomy for acute cholecystitis显示文摘BACKGROUND Recent management of acute cholecystitis favors same admission(SA)or emergent cholecystectomy based on overall shorter hospital stay and therefore cost savings.We adopted the practice of SA cholecystectomy for the treatment of acute cholecystitis at our tertiary care center and wanted to evaluate the economic benefit of this practice.We hypothesized that the existence of complications,particularly among patients with a higher degree of disease severity,during SA cholecystectomy could negate the cost savings.AIM To compare complication rates and hospital costs between SA vs delayed cholecystectomy among patients admitted emergently for acute cholecystitis.METHODS Under an IRB-approved protocol,complications and charges for were obtained for SA,later after conservative management(Delayed),or elective cholecystectomies over an 8.5-year period.Patients were identified using the acute care surgery registry and billing database.Data was retrieved via EMR,operative logs,and Revenue Cycle Operations.The severity of acute cholecystitis was graded according to the Tokyo Guidelines.TG18 categorizes acute cholecystitis by Grades 1,2,and 3 representing mild,moderate,and severe,respectively.Comparisons were analyzed withχ2,Fisher’s exact test,ANOVA,ttests,and logistic regression;significance was set at P<0.05.RESULTS Four hundred eighty-six(87.7%)underwent a SA while 68 patients(12.3%)received Delayed cholecystectomy.Complication rates were increased after SA compared to Delayed cholecystectomy(18.5%vs 4.4%,P=0.004).The complication rates of patients undergoing delayed cholecystectomy was similar to the rate for elective cholecystectomy(7.4%,P=0.35).Mortality rates were 0.6%vs 0%for SA vs Delayed.Patients with moderate disease(Tokyo 2)suffered more complications among SA while none who were delayed experienced a complication(16.1%vs 0.0%,P<0.001).Total hospital charges for SA cholecystectomy were increased compared to a Delayed approach($44500±$59000 vs$35300±$16700,P=0.019).The relative risk of developing a complication was 4.2x[95%confidence interval(CI):1.4-12.9]in the SA vs Delayed groups.Among eight patients(95%CI:5.0-12.3)with acute cholecystitis undergoing SA cholecystectomy,one patient will suffer a complication.CONCLUSION Patients with Tokyo Grade 2 acute cholecystitis had more complications and increased hospital charges when undergoing SA cholecystectomy.This data supports a selective approach to SA cholecystectomy for acute cholecystitis.Christopher P Rice Krishnamurthy B Vaishnavi Celia Chao Daniel Jupiter August B Schaeffer Whitney R Jenson Lance W Griffin William J Mileski 2019World Journal of Gastroenterology2019,25,48:8
2Relationship between HER-2 overexpression and brain metastasis in esophageal cancer patients显示文摘AIM:To study if HER-2 overexpression by locally advanced esophageal cancers increase the chance of brain metastasis following esophagectomy.METHODS:We retrospectively reviewed the medical records of esophageal cancer patients who underwent esophagectomy at University of Iowa Hospitals and Clinics between 2000 and 2010.Data analyzed consisted of demographic and clinical variables.The brain metastasis tissue was assayed for HER-2 overexpression utilizing the FDA approved DAKO Hercept Test.RESULTS:One hundred and forty two patients were reviewed.Median age was 64 years(36-86 years).Eighty eight patients(62%) received neoadjuvant chemoradiotherapy.Pathological complete and partial responses were achieved in 17(19%) and 71(81%) patients.Cancer relapsed in 43/142(30%) patients.The brain was the first site of relapse in 9/43 patients(21%,95% CI:10%-36%).HER-2 immunohistochemistry testing of the brain metastasis tissue showed that 5/9(56%) cases overexpressed HER-2(3+ staining).CONCLUSION:HER-2 overexpression might be associated with increased risk of brain metastasis in esophageal cancer patients following esophagectomy.Further studies will be required to validate this observation.Taher Abu Hejleh Barry R DeYoung Eric Engelman Jeremy M Deutsch Bridget Zimmerman Thorvardur R Halfdanarson Daniel J Berg Kalpaj R Parekh William R Lynch Mark D Iannettoni Sudershan Bhatia Gerald Clamon 2012World Journal of Gastrointestinal Oncology2012,4,5:5
3Characterization of two rat models of cystic fibrosis—KO and F508del CFTR—Generated by Crispr-Cas9显示文摘Background: Genetically engineered animals are essential for gaining a proper understanding of the disease mechanisms of cystic fibrosis(CF). The rat is a relevant laboratory model for CF because of its zootechnical capacity, size, and airway characteristics, including the presence of submucosal glands.Methods: We describe the generation of a CF rat model(F508 del) homozygous for the p.Phe508 del mutation in the transmembrane conductance regulator(Cftr) gene. This model was compared to new Cftr-/-rats(CFTR KO). Target organs in CF were examined by histological staining of tissue sections and tooth enamel was quantified by micro-computed tomography. The activity of CFTR was evaluated by nasal potential difference(NPD) and short-circuit current measurements. The effect of VX-809 and VX-770 was analyzed on nasal epithelial primary cell cultures from F508 del rats.Results: Both newborn F508 del and Knock out(KO) animals developed intestinal obstruction that could be partly compensated by special diet combined with an osmotic laxative. The two rat models exhibited CF phenotypic anomalies such as vas deferens agenesis and tooth enamel defects. Histology of the intestine, pancreas, liver, and lungs was normal. Absence of CFTR function in KO rats was confirmed ex vivo by short-circuit current measurements on colon mucosae and in vivo by NPD, whereas residual CFTR activity was observed in F508 del rats. Exposure of F508 del CFTR nasal primary cultures to a combination of VX-809 and VX-770 improved CFTR-mediated Cl-transport.Conclusions: The F508 del rats reproduce the phenotypes observed in CFTR KO animals and represent a novel resource to advance the development of CF therapeutics.Elise Dreano Marc Bacchetta Juliette Simonin Louise Galmiche Claire Usal Lotfi Slimani Jérémy Sadoine Laurent Tesson Ignacio Anegon Jean-Paul Concordet Aurélie Hatton Lucile Vignaud Danielle Tondelier Isabelle Sermet-Gaudelus Marc Chanson Charles-Henry Cottart 2019Animal Models and Experimental Medicine2019,2,4:3

5Antimicrobial peptides and the gut microbiome in inflammatory bowel disease显示文摘Antimicrobial peptides(AMP)are highly diverse and dynamic molecules that are expressed by specific intestinal epithelial cells,Paneth cells,as well as immune cells in the gastrointestinal(GI)tract.They play critical roles in maintaining tolerance to gut microbiota and protecting against enteric infections.Given that disruptions in tolerance to commensal microbiota and loss of barrier function play major roles in the pathogenesis of inflammatory bowel disease(IBD)and converge on the function of AMP,the significance of AMP as potential biomarkers and novel therapeutic targets in IBD have been increasingly recognized in recent years.In this frontier article,we discuss the function and mechanisms of AMP in the GI tract,examine the interaction of AMP with the gut microbiome,explore the role of AMP in the pathogenesis of IBD,and review translational applications of AMP in patients with IBD.John Gubatan Derek R Holman Christopher J Puntasecca Danielle Polevoi Samuel JS Rubin Stephan Rogalla 2021World Journal of Gastroenterology2021,27,43:3
6Therapeutic drug monitoring in patients with inflammatory bowel disease显示文摘Thiopurine analogs and anti-tumor necrosis factor(TNF)agents have dramatically changed the therapeutics of inflammatory bowel diseases(IBD),improving short and long-term outcomes.Unfortunately some patients do not respond to therapy and others lose response over time.The pharmacokinetic properties of these drugs are complex,with high inter-patient variability.Thiopurine analogs are metabolized through a series of pathways,which vary according to the patients’pharmacogenetic profile.This profile largely determines the ratios of metabolites,which are in turn associated with likelihoods of clinical efficacy and/or toxicity.Understanding these mechanisms allows for manipulation of drug dose,aiming to reduce the development of toxicity while improving the efficacy of treatment.The efficacy of anti-TNF drugs is influenced by many pharmacodynamic variables.Several factors may alter drug clearance,including the concomitant use of immunomodulators(thiopurine analogs and methotrexate),systemic inflammation,the presence of anti-drug antibodies,and body mass.The treatment of IBD has evolved with the understanding of the pharmacologic profiles of immunomodulating and TNF-inhibiting medications,with good evidence for improvement in patient outcomesobserved when measuring metabolic pathway indices.The role of routine measurement of metabolite/drug levels and antibodies warrants further prospective studies as we enter the era of personalized IBD care.Andres J Yarur Maria T Abreu Amar R Deshpande David H Kerman Daniel A Sussman 2014World Journal of Gastroenterology2014,20,13:2
