2Pyrrolidine dithiocarbamate reduces ischemia-reperfusion injury of the small intestine显示文摘AIM: To evaluate whether pyrrolidine dithiocarbamate (PDTC), an enhancer of HO production, attenuates intestinal IR injury.METHODS: Eighteen male rats were randomly allocated into three groups: (a) sham; (b) IR, consisting of 30 min of intestinal ischemia, followed by 2-h period of reperfusion; and (c) PDTC treatment before IR. Intestinal microvascular perfusion (IMP) was monitored continuously by laser Doppler fiowmetry. At the end of the reperfusion, serum samples for lactate dehydrogenase (LDH) levels and biopsies of ileum were obtained. HO activity in the ileum was assessed at the end of the reperfusion period.RESULTS: At the end of the reperfusion in the IR group,IMP recovered partially to 42.5% of baseline (P<0.05vs sham), whereas PDTC improved IMP to 67.3% of baseline (P<0.01 vs IR). There was a twofold increase in HO activity in PDTC group (2 062.66±106.11) as compared to IR (842.3±85.12) (P<0.001). LDH was significantly reduced (P<0.001) in PDTC group (585.6±102.4)as compared to IR group (1 973.8±306.5). Histological examination showed that the ileal mucosa was significantly less injured in PDTC group as compared with IR group.CONCLUSION: Our study demonstrates that PDTC improves the IMP and attenuates IR injury of the intestine possibly via HO production. Additional studies are warranted to evaluate the clinical efficacy of PDTC in the prevention of IR injury of the small intestine.Ismail H Mallick Wen-Xuan Yang Marc C Winslet Alexander M Seifalian 2005World Journal of Gastroenterology2005,11,46:8
3Mobilization of hematopoietic progenitor cells in patients with liver cirrhosis显示文摘AIM:To test the hypothesis that liver cirrhosis is associated with mobilization of hematopoietic progenitor cells. METHODS:Peripheral blood samples from 72 patients with liver cirrhosis of varying etiology were analyzed by flow cytometry.Identified progenitor cell subsets were immunoselected and used for functional assays in vitro. Plasma levels of stromal cell-derived factor-1(SDF-1) were measured using an enzyme linked immunosorbent assay.RESULTS:Progenitor cells with a CD133 + /CD45 + CD14 + phenotype were observed in 61%of th patients.Between 1%and 26%of the peripheral bloo mononuclear cells(MNCs)displayed this phenotype Furthermore,a distinct population of c-kit + progenito cells(between 1%and 38%of the MNCs)could b detected in 91%of the patients.Additionally,18% of the patients showed a population of progenito cells(between 1%and 68%of the MNCs)that wa characterized by expression of breast cancer resistanc protein-1.Further phenotypic analysis disclosed tha the circulating precursors expressed CXC chemokin receptor 4,the receptor for SDF-1.In line with thi finding,elevated plasma levels of SDF-1 were presen in all patients and were found to correlate with th number of mobilized CD133 + progenitor cells.Ursula M Gehling Marc Willems Kathleen Schlagner Ralf A Benndorf Maura Dandri Jrg Petersen Martina Sterneck Joerg-Matthias Pollok Dieter K Hossfeld Xavier Rogiers 2010World Journal of Gastroenterology2010,16,2:4
4Outcome in obscure gastrointestinal bleeding after capsule endoscopy显示文摘AIM: To investigate the clinical impact of capsule endoscopy(CE) after an obscure gastrointestinal bleeding(OGIB) episode, focusing on diagnostic work-up, followup and predictive factors of rebleeding. METHODS: Patients who were referred to Hospital del Mar(Barcelona, Spain) between 2007 and 2009 for OGIB who underwent a CE were retrospectively analyzed. Demographic data, current treatment with non-steroid antiinflammtory drugs or anticoagulant drugs, hemoglobin levels, transfusion requirements, previous diagnostic tests for the bleeding episode, as well as CE findings(significant or non-significant), work-up and patient out-comes were analyzed from electronic charts. Variables were compared by χ 2 analysis and Student t test. Risk factors of rebleeding were assessed by Log-rank test, Kaplan-Meier curves and Cox regression model. RESULTS: There were 105 patients [45.7% women, median age of 72 years old(interquartile range 56-79)] and a median follow-up of 326 d(interquartile range 123-641) included in this study. The overall diagnostic yield of CE was 58.1%(55.2% and 63.2%, for patients with occult OGIB and overt OGIB, respectively). In 73 patients(69.5%), OGIB was resolved. Multivariate analysis showed that hemoglobin levels lower than 8 g/dL at diagnosis [hazard ratios(HR) = 2.7, 95%CI: 1.9-6.3], patients aged 70 years and above(HR = 2.1, 95%CI: 1.2-6.1) and significant findings in CE(HR = 2.4, 95%CI: 1.1-5.8) were independent predictors of rebleeding. CONCLUSION: One third of the patients presented with rebleeding after CE; risk factors were hemoglobin levels < 8 g/dL, age ≥ 70 years or the presence of significant lesions.Alex Caas-Ventura Lucia Márque Xavier Bessa Josep Maria DedeuDepartment of Gastroenterology Hospital del Mar Research Institute Pompeu Fabra University Marc Puigvehí Sílvia Delgado-Aros Ines Ana Ibáez Agustin Seoane Luis Barranco Felipe Bory Montserrat Andreu Begoa González-Suárez 2013World Journal of Gastrointestinal Endoscopy2013,5,11:4
5BK nephropathy in the native kidneys of patients with organ transplants: Clinical spectrum of BK infection显示文摘Nephropathy secondary to BK virus, a member of the Papoviridae family of viruses, has been recognized for some time as an important cause of allograft dysfunction in renal transplant recipients. In recent times, BK nephropathy(BKN) of the native kidneys has being increasingly recognized as a cause of chronic kidney disease in patients with solid organ transplants, bone marrow transplants and in patients with other clinical entities associated with immunosuppression. In such patients renal dysfunction is often attributed to other factors including nephrotoxicity of medications used to prevent rejection of the transplanted organs. Renal biopsy is required for the diagnosis of BKN. Quantitation of the BK viral load in blood and urine are surrogate diagnostic methods. The treatment of BKN is based on reduction of the immunosuppressive medications. Several compounds have shown antiviral activity, but have not consistently shown to have beneficial effects in BKN. In addition to BKN, BK viral infection can cause severe urinary bladder cystitis, ureteritis and urinary tract obstruction as well as manifestations in other organ systems including the central nervous system, the respiratory system, the gastrointestinal system and the hematopoietic system. BK viral infection has also been implicated in tumorigenesis. The spectrum of clinical manifestations from BK infection and infection from other members of the Papoviridae family is widening. Prevention and treatment of BK infection and infections from other Papovaviruses are subjects of intense research.Darlene Vigil Nikifor K Konstantinov Marc Barry Antonia M Harford Karen S Servilla Young Ho Kim Yijuan Sun Kavitha Ganta Antonios H Tzamaloukas 2016World Journal of Transplantation2016,6,3:4
6Large endoscopic mucosal resection for colorectal tumors exceeding 4 cm显示文摘AIM:To evaluate the feasibility and the outcome of endoscopic mucosal resection(EMR)for large colorectal tumors exceeding 4 cm(LCRT)undergoing piecemeal resection. METHODS:From January 2005 to April 2008,146 digestive tumors larger than 2 cm were removed with the EMR technique in our department.Of these,34 tumors were larger than 4 cm and piecemeal resection was carried out on 26 colorectal tumors.The mean age of the patients was 71 years.The mean follow-up duration was 12 mo. RESULTS:LCRTs were located in the rectum,left colon,transverse colon and right colon in 58%,15%, 4%and 23%of cases,respectively.All were sessile tumors larger than 4 cm with a mean size of 4.9 cm (4-10 cm).According to the Paris classification,34%of the tumors were typeⅠs,58%typeⅡa,4%typeⅡb and 4%typeⅡc.Pathological examination showed tubulous adenoma in 31%,tubulo-villous adenoma in 27%,villous adenoma in 42%,high-grade dysplasia in38%,in situ carcinoma in 19%of the cases and mucosal carcinoma(m2)in 8%of the cases.The two cases(7.7%)of procedural bleeding that occurred were managed endoscopically and one small perforation was treated with clips.During follow-up,recurrence of the tumor occurred in three patients(12%),three of whom received endoscopic treatment. CONCLUSION:EMR for tumors larger than 4 cm is a safe and effective procedure that could compete with endoscopic submucosal dissection,despite providing incomplete histological assessment.Philippe Ah Soune Charles Ménard Ezzedine Salah Ariadne Desjeux Jean-Charles Grimaud Marc Barthet 2010World Journal of Gastroenterology2010,16,5:4

9Diffusion-weighted magnetic resonance imaging in cancer: Reported apparent diffusion coefficients,in-vitro and invivo reproducibility显示文摘There is considerable disparity in the published apparent diffusion coefficient(ADC) values across different anatomies. Institutions are increasingly assessing repeatability and reproducibility of the derived ADC to determine its variation,which could potentially be used as an indicator in determining tumour aggressiveness or assessing tumour response. In this manuscript,a review of selected articles published to date in healthy extracranial body diffusion-weighted magnetic resonance imaging is presented,detailing reported ADC values and discussing their variation across different studies. In total 115 studies were selected including 28 for liver parenchyma,15 for kidney(renal parenchyma),14 for spleen,13 for pancreatic body,6 for gallbladder,13 for prostate,13 for uterus(endometrium,myometrium,cervix) and 13 for fibroglandular breast tissue. Median ADC values in selected studies were found to be 1.28 × 10-3 mm2/s in liver,1.94 × 10-3 mm2/s in kidney,1.60 × 10-3 mm2/s in pancreatic body,0.85 × 10-3 mm2/s in spleen,2.73 × 10-3 mm2/s in gallbladder,1.64 × 10-3 mm2/s and 1.31 × 10-3 mm2/s in prostate peripheral zone and central gland respectively(combined median value of 1.54×10-3 mm2/s),1.44 × 10-3 mm2/s in endometrium,1.53 × 10-3 mm2/s in myometrium,1.71 × 10-3 mm2/s in cervix and 1.92 × 10-3 mm2/s in breast. In addition,six phantom studies and thirteen in vivo studies were summarized to compare repeatability and reproducibility of the measured ADC. All selected phantom studies demonstrated lower intra-scanner and inter-scanner variation compared to in vivo studies. Based on the findings of this manuscript,it is recommended that protocols need to be optimised for the body part studied and that system-induced variability must be established using a standardized phantom in any clinical study. Reproducibility of the measured ADC must also be assessed in a volunteer population,as variations are far more significant in vivo compared with phantom studies.Maysam M Jafar Arman Parsai Marc E Miquel 2016World Journal of Radiology2016,8,1:2
10Bovine immunoglobulin protein isolates for the nutritional management of enteropathy显示文摘The gastrointestinal tract is responsible for a multitude of digestive and immune functions which depend upon the balanced interaction of the intestinal microbiota, diet, gut barrier function, and mucosal immune response. Disruptions in one or more of these factors can lead to intestinal disorders or enteropathies which are characterized by intestinal inflammation, increased gut permeability, and reduced capacity to absorb nutrients. Enteropathy is frequently associated with human immunodeficiency virus(HIV) infection, inflammatory bowel disease, autoimmune enteropathy, radiation enteritis, and irritable bowel syndrome(IBS), where pathologic changes in the intestinal tract lead to abdominal discomfort, bloating, abnormal bowel function(e.g., diarrhea, urgency, constipation and malabsorption). Unfortunately, effective therapies for the management ofenteropathy and restoring intestinal health are still not available. An accumulating body of preclinical studies has demonstrated that oral administration of plasmaor serum-derived protein concentrates containing high levels of immunoglobulins can improve weight, normalize gut barrier function, and reduce the severity of enteropathy in animal models. Recent studies in humans, using serum-derived bovine immunoglobulin/protein isolate, demonstrate that such protein preparations are safe and improve symptoms, nutritional status, and various biomarkers associated with enteropathy. Benefits have been shown in patients with HIV infection or diarrhea-predominant IBS. This review summarizes preclinical and clinical studies with plasma/serum protein concentrates and describes the effects on host nutrition, intestinal function, and markers of intestinal inflammation. It supports the concept that immunoglobulin-containing protein preparations may offer a new strategy for restoring functional homeostasis in the intestinal tract of patients with enteropathy.Bryon W Petschow Anthony T Blikslager Eric M Weaver Joy M Campbell Javier Polo Audrey L Shaw Bruce P Burnett Gerald L Klein J Marc Rhoads 2014World Journal of Gastroenterology2014,20,33:2
11Microstructural analysis of pineal volume using trueFISP imaging显示文摘AIM:To determine the spectrum of pineal microstructures (solid/cystic parts) in a large clinical population using a high-resolution 3D-T2-weighted sequence. METHODS:A total of 347 patients enrolled for cranial magnetic resonance imaging were randomly included in this study. Written informed consent was obtained from all patients. The exclusion criteria were artifacts or mass lesions prohibiting evaluation of the pineal gland in any of the sequences. True-FISP-3D-imaging (1.5-T, isotropic voxel 0.9 mm) was performed in 347 adults (55.4 ± 18.1 years). Pineal gland volume (PGV), cystic volume, and parenchyma volume (cysts exclud- ed) were measured manually. RESULTS:Overall, 40.3% of pineal glands were cystic. The median PGV was 54.6 mm 3 (78.33 ± 89.0 mm 3 ), the median cystic volume was 5.4 mm 3 (15.8 ± 37.2mm 3 ), and the median parenchyma volume was 53.6 mm 3 (71.9 ± 66.7 mm 3 ). In cystic glands, the standard deviation of the PGV was substantially higher than in solid glands (98% vs 58% of the mean). PGV declined with age (r = -0.130, P = 0.016). CONCLUSION:The high interindividual volume variation is mainly related to cysts. Pineal parenchyma volume decreased slightly with age, whereas genderrelated effects appear to be negligible.Jan M Bumb Marc A Brockmann Christoph Groden Ingo Nolteb 2013World Journal of Radiology2013,5,4:2
12Orthopaedic care provided by the 14th combat support hospital in support of humanitarian and disaster relief after hurricane Maria in Puerto Rico显示文摘On September 20,2017 Hurricane Maria,a category 4 hurricane,made landfall on the eastern coast of Puerto Rico.This was preceded by Hurricane Irma,a category 5 hurricane,which passed just off the coast 13 d prior.The destruction from both Hurricane Irma and Maria precipitated a coordinated federal response which included the Federal Emergency Management Agency(FEMA)and the United States military.The United States Army dispatched the 14^th Combat Support Hospital(CSH)to Humacao,a city on the eastern side of the island where Maria made landfall.The mission of the 14^th CSH was to provide medical humanitarian aid and conduct disaster relief operations in support of the government of Puerto Rico and FEMA.During the 14^th CSH deployment to Puerto Rico,1157 patients were evaluated and treated.Fifty-seven operative cases were performed to include 23 orthopaedic cases.The mean age of the orthopaedic patients treated was 45.7 years(range 13-76 years).The most common operation was irrigation and debridement of open contaminated and/or infected wounds.Patients presented a mean 10.8 d from their initial injury(range 1-40 d).Fractures and infections were the most common diagnoses with the greatest delay in treatment from the initial date of injury.The deployment of the 14^th CSH to Puerto Rico was unique in its use of air transport,language and local customs encountered,as well as deployment to a location outside the continental United States.These factors coupled with the need for rapid deployment of the 14^th CSH provided valuable experience which will undoubtedly enable future success in similar endeavors.Nathan Lanham Kyle Bockelman Fernando Lopez Marc M Serra Bradford Scanlan 2020World Journal of Orthopedics2020,11,2:2
