A human iPSC-astroglia neurodevelopmental design unveils divergent transcriptomic habits inside schizophrenia.
Background The impact of anastomotic leak (AL) on long-term outcomes after gastrectomy for gastric adenocarcinoma is poorly understood. This study determined whether AL contributes to poor overall survival. Methods Consecutive patients undergoing gastrectomy in a single high-volume unit between 1997 and 2016 were evaluated. Clinicopathological characteristics, oncological and postoperative outcomes were stratified according to whether patients had no AL, non-severe AL or severe AL. Severe AL was defined as anastomotic leakage associated with Clavien-Dindo Grade III-IV complications. Results The study included 969 patients, of whom 58 (6·0 per cent) developed AL; 15 of the 58 patients developed severe leakage. Severe AL was associated with prolonged hospital stay (median 50, 30 and 13 days for patients with severe AL, non-severe AL and no AL respectively; P less then 0·001) and critical care stay (median 11, 0 and 0 days; P less then 0·001). There were no significant differences between groups in number of lymph nodes harvested (median 29, 30 and 28; P = 0·528) and R1 resection rates (7, 5 and 6·5 per cent; P = 0·891). Cox multivariable regression analysis showed that severe AL was independently associated with overall survival (hazard ratio 3·96, 95 per cent c.i. CDK2-IN-73 mouse 2·11 to 7·44; P less then 0·001) but not recurrence-free survival. In sensitivity analysis, the results for patients who had neoadjuvant therapy then gastrectomy were similar to those for the entire cohort. Conclusion AL prolongs hospital stay and is associated with compromised long-term overall survival.Background B cells play a crucial role during rhinovirus (RV) infections by production of virus-neutralizing antibodies. A main feature of common variable immunodeficiency (CVID) is hypogammaglobulinemia (HG). HG patients have severely reduced levels of antibody-producing B cells and suffer from prolonged virus infections. Here, we addressed whether antiviral response of peripheral blood lymphocytes differs between HG patients and healthy individuals during natural RV infection. Methods Using fluorescence-activated cell sorting, B cell subsets were analyzed. Simultaneously, CD19+ B cells, CD14+ monocytes and CD3+ T cells were sorted from frozen peripheral blood mononuclear cells from 11 RV-infected hypogammaglobulinemia patients, 7 RV-infected control subjects and 14 non-infected control subjects. Real-time PCR was used to study expression of antiviral genes. A pan-RV PCR was used to detect RV genome in all samples. Results In HG patients, total B cell numbers, as well as IgA+ and IgG+ switched memory B cells were reduced while naïve B cells and T cells were increased. STAT1 expression was increased in HG patients compared to controls in all lymphocyte subsets analyzed. The expression of antiviral genes IFITM1 and MX1 correlated with STAT1 expression in B cells and monocytes. RV RNA was found in 88.9 % of monocytes from infected HG patients, 85.7 % of monocytes from infected controls and 7.1 % of monocytes from uninfected controls. Conclusions We demonstrate an increased antiviral response in B cells and monocytes in HG patients and their correlation with STAT1 expression. Monocytes of infected HG patients and infected non-HG controls carry RV RNA.Myeloid cells infiltrate into the liver and differentiate into macrophages in different liver-injury mouse models. However, the heterogeneity of bone marrow (BM) -derived LMs populations remains to be understood. To investigate this and understand the impact of the macrophage niche on the properties of recruited BM-derived macrophages, we used a non-myeloablation BM transplantation model to label and trace BM-derived LMs. Subsequently, we quantified the number of embryonic-derived liver-resident macrophages, BM-derived LMs, and total LMs, in CCl4 and irradiated acute liver injury mouse models respectively. Finally, we compared the cell fate, gene-expression patterns, chemokine signals, and surface markers of irradiated and CCl4 -treated BM-derived LMs. We observed that, as compared to CCl4, radiation generated a macrophage niche by depleting embryonic-derived liver-resident macrophages, and induced the recruitment of BM-derived LMs that further settled in the liver. Irradiated and CCl4 -treated BM-derived LMs are different with respect to their cell fates, gene-expression patterns, and chemokine expression and recruitment. They also have different surface markers shortly after differentiating from their progenitors. Our findings suggest that irradiated and CCl4 -treated LM populations derived from the bone-marrow display different patterns of gene expression and phenotypes; these differences may be due to the availability of macrophage-niche.We present an Executive Summary of a guideline produced by a Joint British Diabetes Societies for Inpatient Care Writing Group for managing frail older inpatients with diabetes. This represents a multidisciplinary stakeholder consensus document providing more than 100 recommendations in eight areas functional assessment and detection of frailty; preventative care assessing risk factors and avoiding hospital admissions; general inpatient management principles; managing therapy choices for the frail older inpatient with diabetes; managing associated comorbidities and concerns; pre-operative assessment and care; discharge planning and principles of follow-up; and end of life care. The document is intended to guide effective clinical decision-making in an inpatient setting and is supported by four appendices Appendix 1, STOPPFRAIL criteria; Appendix 2, Acute care toolkit 3-Royal College of Physicians; Appendix 3, a description of physical performance and frailty measures for routine NHS application; and Appendix 4, Inpatient Frailty Care Pathway-template. This document is expected to enhance clinical outcomes and overall health status for this vulnerable inpatient population of older people with diabetes.

The plant supplies carbon substrates and other nutrients to the bacteria in exchange for fixed nitrogen. The exchange occurs across a plant-derived symbiosome membrane (SM), which encloses rhizobia to form a symbiosome. Iron supplied by the plant is crucial for rhizobial enzyme nitrogenase that catalyses N2 fixation, but the SM iron transporter has not been identified. We use yeast complementation, real-time PCR and proteomics to study putative soybean (Glycine max) iron transporters GmVTL1a and 1b and have characterised the role of GmVTL1a using complementation in plant mutants, hairy root transformation and microscopy. GmVTL1a and 1b are members of the vacuolar iron transporter family and homologous to Lotus japonicus SEN1 (LjSEN1), which is essential for N2 fixation. GmVTL1a expression is enhanced in nodule infected cells and both proteins are localised to the SM. GmVTL1a transports iron in yeast and restores N2 fixation when expressed in the Ljsen1 mutant.
