In vitro, PIK3R3 regulates ZO-1 by activating NF-kB pathway. Overexpression of PIK3R3 in Caco-2 cells decreased transepithelial electrical resistance (TEER), an opposite result was observed in siPIK3R3 cells. In animal study, inhibition of PIK3R3 by N15 contributed to amelioration of DSS-induced intestinal permeability. Mice treated with N15 exhibited less disruption of TJs in colon tissues. Conclusions PIK3R3 was increased in clinical IBD patients with accompanying disruption of ZO-1 expression. Inhibition of PIK3R3 attenuated DSS-induced IBD symptoms in a mouse model. These findings indicated that PIK3R3 could be a therapeutic target for IBD.Urinary trypsin inhibitor (UTI), also known as ulinastatin, has been reported to protect multiple organs against inflammation- and/or injury-induced dysfunction. In the present study, we aimed to investigate the immunomodulation effects of a recombinant human ulinastatin (urinary trypsin inhibitor, UTI) (rhUTI) on splenic dendritic cells (DCs) in cecal ligation and puncture (CLP)-induced septic mice. CLP mice were treated with rhUTI intramuscularly at 0, 12, and 24 h after procedure. Splenic CD11c+ DCs were isolated and accessed with flow cytometry for apoptotic or phenotypic analysis. Protein markers and cytokines were determined with Western blotting or ELISA. Treatment with rhUTI could markedly upregulate levels of costimulatory molecules (CD80, CD86) and MHC-II on surface of the splenic DC in CLP mice. The apoptotic rate of splenic DCs was decreased in CLP mice after rhUTI treatment. The survival rate of septic mice was increased after treatment with rhUTI. In addition, protein level of markers in endoplasmic reticulum stress (ERS)-related apoptotic pathways (including GRP78, caspase-12, and CHOP) were obviously down-regulated in the rhUTI-treated group when compared with the CLP group. These results indicate that rhUTI protects CLP-induced sepsis in mice by improving immune response of splenic DCs and inhibiting the excessive ERS-mediated apoptosis.We attempted to detect circulating tumor DNA (ctDNA), taking advantage of molecular barcode next-generation sequencing (MB-NGS), which can be more easily customized to detect a variety of mutations with a high sensitivity than PCR-based methods. Sequencing with a gene panel consisting of the 13 most frequently mutated genes in breast tumors from stage I or II patients revealed 95 somatic mutations in the 12 genes in 62% (62/100) of tumors. Then, plasma DNA from each patient (n = 62) before surgery was analyzed via MB-NGS customized to each somatic mutation, resulting in the detection of ctDNA in 16.1% (10/62) of patients. ctDNA was significantly associated with biologically aggressive phenotypes, including large tumor size (P = .004), positive lymph node (P = .009), high histological grade (P less then .001), negative ER (P = .018), negative PR (P = .017), and positive HER2 (P = .046). Furthermore, distant disease-free survival was significantly worse in patients with ctDNA (n = 10) than those without ctDNA (n = 52) (P less then .001). Our results demonstrate that MB-NGS personalized to each mutation can detect ctDNA with a high sensitivity in early breast cancer patients at diagnosis, and it seems to have a potential to serve as a clinically useful tumor marker for predicting their prognosis.Context Constipation occurs in up to 71.7% (33/46) of hospital inpatients taking opioid analgesics. Co-prescribing laxatives with opioid analgesics is recommended to prevent opioid-induced constipation. Objectives This study aimed to examine the effect of an electronic medical record (EMR) design modification to increase laxative co-prescribing among hospitalised inpatients taking opioid analgesics. Methods In this retrospective 3-month before-and-after study, an EMR modification to improve docusate with sennosides order sentence visibility was implemented on 21 February 2018, at a teaching hospital in Sydney, Australia. The primary outcome was the co-prescription rate of docusate with sennosides within 24-h of the first opioid analgesic administered. Darolutamide International Classification of Diseases 10th Revision Australian Modification diagnosis codes were collected from the EMR. Multivariable logistic regression was performed to determine the impact of the EMR modification on co-prescribing of laxatives with opioid analgesics. Results Of the 1832 adult inpatients included in the study (51.0% male), 50.5% were admitted before the EMR modification implementation and 49.5% were admitted afterwards. Docusate with sennosides was co-prescribed in 12.5% of patients before and 14.9% of patients after the EMR modification. Although the EMR modification did not change laxative co-prescribing among surgical patients (odds ratio [OR] = 1.1, 95% confidence interval [CI] 0.8-1.6, p = 0.54), a significant increase in co-prescription of docusate with sennosides among aged care patients (OR = 1.8, 95% CI 1.0-3.0, p = 0.03) was observed. Conclusions An EMR design modification did not change laxative co-prescribing in hospital inpatients overall. However, the EMR modification was associated with a significant increase in laxative co-prescribing among aged care patients prescribed opioid analgesics.Background Although barriers exist to secondary use of primary care electronic medical record (EMR) data, the Alliance for Healthier Communities (the Alliance) in Ontario, Canada has successfully created one of the largest structured primary care EMR datasets in Canada. In 2018, the Alliance and the Canadian Institute for Health Information (CIHI), an organization that provides comparable and actionable data to accelerate improvements in health across Canada, entered into a partnership to share EMR data. In this paper, we describe (i) the processes that enabled the collection of structured EMR data by the Alliance; (ii) how CIHI connected with the Alliance to share data and assess its quality; and, (iii) demonstrate the value of linking structured EMR data to administrative acute care data in illustrating the patient journey through the care continuum, using COPD as a case study. Methods CIHI and the Alliance entered into a formal data sharing agreement that enabled the sharing of linkable structured EMR data by the Alliance's 75 community health centres (CHCs) with CIHI.
