The lower levels of miR-602 and higher concentration of S100B in the sera of IS patients could be associated with clinically significant diagnostic utilities. S100B could be also introduced as a reliable prognostic marker for stroke and implemented in future research.Cerebral amyloid angiopathy (CAA) is one of the major types of cerebral small vessel disease, and a leading cause of spontaneous intracerebral hemorrhage and cognitive decline in elderly patients. Although increasingly detected, a number of aspects including the pathophysiology, the clinical and neuroradiological phenotype, and the disease course are still under investigation. The incomplete knowledge of the disease limits the implementation of evidence-based guidelines on patient's clinical management and the development of treatments able to prevent or reduce disease progression. The SENECA (SEarchiNg biomarkErs of Cerebral Angiopathy) project is the first Italian multicenter cohort study aimed at better defining the disease natural history and identifying clinical and neuroradiological markers of disease progression. By a multidisciplinary approach and the collection of a large and well-phenotyped series and biorepository of CAA patients, the study is ultimately expected to improve the diagnosis and the knowledge of CAA pathophysiological mechanisms.BACKGROUND The burden of emergency general surgery conditions is high in sub-Saharan Africa, and poor access to surgical care leads to poor patient outcomes. Selleckchem Phlorizin We examined the trends in mortality in patients presenting with an acute abdomen to a referral hospital. METHODS A retrospective analysis of the prospectively collected Kamuzu Central Hospital Acute Care Surgery database was performed (January 2014 to July 2019). Bivariate analysis was conducted by year of admission. A multivariate Poisson regression was performed to identify predictors of mortality. RESULTS During the study, 2509 patients with acute abdomen presented. The majority of patients presenting were transferred from outside hospitals (n = 2097, 83.9%). Mortality was highest in patients with preoperative diagnosis of peritonitis (n = 119, 22.2%), bowel obstruction (n = 214, 18.7%), and volvuli (n = 51, 18.6%). There was no difference in mortality by year, p = 0.1. On multivariate Poisson regression, there was an increased relative risk of mortality with being transferred (RR 1.31, 95% CI 1.12-1.55, p = 0.002), as well as undergoing an operation within 1-2 days (RR 1.48, 95% CI 1.16-1.87, p 2 days (RR 1.46, 95% CI 1.17-1.82, p = 0.001) after presentation. CONCLUSION The majority of patients in our study who presented with an acute abdomen were transferred from district hospitals, which resulted in high mortality due to delays in surgical care. Therefore, the WHO's recommendation that the majority of district hospitals perform the Bellwether procedures does not occur in district hospitals in central Malawi. District hospitals require significant resource investment to reduce transfers needs and patient mortality.INTRODUCTION This network meta-analysis aimed to identify the reconstruction technique associated with lowest rates of DGE following pancreatoduodenectomy (PD) from randomised controlled trials (RCTs). METHODS A systematic literature search of PubMed, Embase and MEDLINE databases was carried out using the PRISMA framework to identify all RCTs comparing reconstruction techniques of gastrojejunostomy after PD, with overall DGE as the primary endpoint. The primary outcome measure was overall DGE. Secondary outcomes were grade B/C DGE, duration of nasogastric tube, time to solid food intake, overall and grade B/C pancreatic fistula, bile leaks, reoperation, length of hospital stay and in-hospital mortality. RESULTS The search strategy identified eight RCTs including 761 patients. Six RCTs compared antecolic (n = 291 patients) and retrocolic Billroth II (n = 289 patients) reconstruction (n = 6 studies), and two RCTs compared antecolic Billroth II (n = 92 patients) and Roux-en-Y (n = 89 patients) reconstruction. Overall, antecolic Billroth II ranked best for overall and grade B/C DGE, bile leak, surgical site infection, length of stay and in-hospital mortality. Roux-en-Y was best for overall and grade B/C pancreatic fistula. CONCLUSION Antecolic Billroth II gastroenteric reconstruction is associated with the lowest rates of delayed gastric emptying after PD amongst the currently available techniques of gastrojejunostomy reconstructions.BACKGROUND Field resistance is often effective and durable as compared to vertical resistance. The introgression line (INGR15002) derived from O. glumaepatula has proven broad spectrum field resistance for both leaf and neck blast. RESULTS Quantitative Trait Loci (QTL) analysis of INGR15002, led to the identification of two major QTL - qBL3 contributing about 34% and 32% phenotypic variance towards leaf and neck blast resistance, respectively and qBL7 contributing about 25% of phenotypic variance for leaf blast. Further, qBL3 was fine mapped, narrowed down to 300 kb region and a linked SNP maker was identified. By combining mapping with microarray analysis, a candidate gene, Os03g0281466 (malectin-serine threonine kinase), was identified in the fine mapped region and named as Pi68(t). The nucleotide variations in the coding as well as upstream region of the gene was identified through cloning and sequence analysis of Pi68(t) alleles. These significant variations led to the non-synonymous changes in the protein as well as variations (presence/absence) in four important motifs (W-box element; MYC element; TCP element; BIHD1OS) at promoter region those are associated with resistance and susceptible reactions. The effect of qBL3 was validated by its introgression into BPT5204 (susceptible variety) through marker-assisted selection and progeny exhibiting resistance to both leaf and neck blast was identified. Further, the utility of linked markers of Pi68(t) in the blast breeding programs was demonstrated in elite germplasm lines. CONCLUSIONS This is the first report on the identification and characterization of major effect QTL from O. glumaepatula, which led to the identification of a putative candidate gene, Pi68(t), which confers field resistance to leaf as well as neck blast in rice.
