Postpolypectomy bleeding is the most common adverse event with pedunculated polyps. We clarified the endoscopic characteristics influencing postpolypectomy bleeding for pedunculated colonic polyps.
We reviewed clinical data for 1147 pedunculated colonic polyps removed by polypectomy in 5 Japanese institutions. Pedunculated polyps were defined as polyps with a stalk length≥5mm. Analyzed clinical data were age, sex, polyp location/size, stalk length/width, prophylactic clipping or endoloop before polypectomy, injecting the stalk, closing the polypectomy site, antithrombotic agent use, and endoscopist experience. Postpolypectomy bleeding was classified as immediate bleeding or delayed bleeding.
Immediate and delayed bleeding was observed in 8.5% (97/1147) and 2% (23/1147) of polypectomies, respectively. Comparing immediate bleeding with nonbleeding, multivariate analysis showed that stalk width≥6mm (odds ratio [OR], 1.9; 95% confidence interval [CI], 1.1-3.4) was a significant risk factor for immediate bleg with polyp size ≥15 mm.
We previously identified a 5 methylated DNA marker (MDM) panel for the detection of nonendoscopic Barrett's esophagus (BE). In this study, we aimed to recalibrate the performance of the 5 MDM panel using a simplified assay in a training cohort, validate the panel in an independent test cohort, and explore the accuracy of an MDM panel with only 3 markers.
Participants were recruited from 3 medical centers. The sponge on a string device (EsophaCap; CapNostics, Concord, NC, USA) was swallowed and withdrawn, followed by endoscopy, in BE cases and control subjects. A 5 MDM panel was blindly assayed using a simplified assay. Random forest modeling analysis was performed, in silico cross-validated in the training set, and then locked down, before test set analysis.
The training set had 199 patients 110 BE cases and 89 control subjects, and the test set had 89 patients 60 BE cases and 29 control subjects. Sensitivity of the 5 MDM panel for BE diagnosis was 93% at 90% specificity in the training set and 93% at 93% specificity in the test set. Areas under the receiver operating characteristic curves were .96 and .97 in the training and test sets, respectively. Model accuracy was not influenced by age, sex, or smoking history. Multiple 3 MDM panels achieved similar accuracy.
A 5 MDM panel for BE is highly accurate in training and test sets in a blinded multisite case-control analysis using a simplified assay. This panel may be reduced to only 3 MDMs in the future. (Clinical trial registration number NCT02560623.).

(Clinical trial registration number NCT02560623.).Low-dose total body irradiation (TBI) has long been used in nonmyeloablative conditioning (NMAC) regimens before allogeneic stem cell transplantation from haploidentical donors (haplo-SCT). More recently, the use of total marrow lymphoid irradiation (TMLI) instead of TBI in conditioning is increasing. This study aimed to evaluate outcomes in a cohort of patients treated with low-dose TMLI in terms of engraftment, full donor chimerism status, graft-versus-host disease (GVHD), and extrahematologic toxicities, and to compare these outcomes with those in a cohort of patients receiving conventional TBI-containing conditioning. This retrospective single-center study included 100 patients with advanced hematologic malignancies who underwent haplo-SCT. Between 2009 and 2011, the NMAC regimen consisted of cyclophosphamide, fludarabine, and low-dose TBI (2 Gy), and after 2011, TBI was replaced with TMLI (2 Gy). Patients received post-transplantation cyclophosphamide, calcineurin inhibitor, and mycophenolate mofetil as strongest finding was that TBI can be safely replaced by TMLI in terms of engraftment, achievement of full donor chimerism status, GVHD incidence, and extrahematologic toxicities.Despite advances in understanding the biology of mature T and natural killer (NK)/T cell neoplasia, current therapies, even the most innovative ones, are still far from ensuring its cure. The only treatment to date that has been shown to control aggressive T cell neoplasms in the long term is allogeneic stem cell transplantation (alloSCT). GSK1070916 solubility dmso We aim to report the results of alloSCT for advanced mature T and NK/T neoplasias performed in centers from our national GELTAMO/GETH (Grupo Español de Linfoma y Trasplante de Médula Ósea/Grupo Español de Trasplante Hematopoyético y Terapia Celular) over the past 25 years. As a secondary objective, we analyzed the results of alloSCT from haploidentical donors. We performed a retrospective analysis of all patients who received an alloSCT in Spanish centers (n = 201) from September 1995 to August 2018. The 2-year overall survival (OS) and disease-free survival (DFS) were 65.5% and 58.2%, respectively. The univariate for OS and DFS showed statistically different hazard ratios for conditioning intensity, response pre-alloSCT, comorbidity index, donor/receptor cytomegalovirus status and Eastern Cooperative Oncology Group (ECOG) pre-alloSCT, but only a better ECOG pre-alloSCT remained significant in the multivariate analysis. There was an increased incidence of relapse in those patients who did not develop chronic graft-versus-host disease (GVHD) and an increased risk of death in those developing moderate to severe acute GVHD. The 1-year nonrelapse mortality was 21.9% and was mainly due to GVHD (30%) and bacterial infections (17%). When comparing unrelated donors with haploidentical donors, we found similar results in terms of OS and DFS. There was, however, a reduction of acute GVHD in the haploidentical group (P = .04) and trend to a reduction of chronic GVHD. In conclusion, alloSCT is the only curative option for most aggressive T cell neoplasias. Haploidentical donors offer similar results to related donors in terms of survival with a reduction of acute GVHD.Hepatitis C virus (HCV) is a global public health problem in correctional settings. The International Network on Health and Hepatitis in Substance Users-Prisons Network is a special interest group committed to advancing scientific knowledge exchange and advocacy for HCV prevention and care in correctional settings. In this Review, we highlight seven priority areas and best practices for improving HCV care in correctional settings changing political will, ensuring access to HCV diagnosis and testing, promoting optimal models of HCV care and treatment, improving surveillance and monitoring of the HCV care cascade, reducing stigma and tackling the social determinants of health inequalities, implementing HCV prevention and harm reduction programmes, and advancing prison-based research.
