Are young children just random explorers who learn serendipitously? Or are even young children guided by uncertainty-directed sampling, seeking to explore in a systematic fashion? We study how children between the ages of 4 and 9 search in an explore-exploit task with spatially correlated rewards, where exhaustive exploration is infeasible and not all options can be experienced. By combining behavioral data with a computational model that decomposes search into similarity-based generalization, uncertainty-directed exploration, and random exploration, we map out developmental trajectories of generalization and exploration. The behavioral data show strong developmental differences in children's capability to exploit environmental structure, with performance and adaptiveness of sampling decisions increasing with age. Through model-based analyses, we disentangle different forms of exploration, finding signature of both uncertainty-directed and random exploration. The amount of random exploration strongly decreases as children get older, supporting the notion of a developmental "cooling off" process that modulates the randomness in sampling. However, even at the youngest age range, children do not solely rely on random exploration. Even as random exploration begins to taper off, children are actively seeking out options with high uncertainty in a goal-directed fashion, and using inductive inferences to generalize their experience to novel options. Our findings provide critical insights into the behavioral and computational principles underlying the developmental trajectory of learning and exploration. Ileostomy formation is a commonly performed procedure with substantial associated morbidity. Patients with an ileostomy experience high rates of unplanned hospital readmission with dehydration, and such events have a long-term health and economic impact. Reports of the significant risk factors associated with these readmissions have been inconsistent. This study aimed to identify the significant risk factors for readmission with dehydration following ileostomy formation. A systematic search was conducted using the Medline, Embase, Cochrane and CINAHL databases. All original research articles reporting risk factors for readmission with dehydration following ileostomy formation in adults were included. The primary outcome was the pooled risk ratio of clinically relevant variables potentially associated with dehydration-related readmission following ileostomy formation. The secondary outcome was the incidence of dehydration-related readmission. Ten studies (27089 patients) were included. The incidences of s addressing risk prediction, allow risk stratification of ileostomates and aid in the development of personalized prevention strategies.Proanthocyanidins (PAs), also known as condensed tannins, are plant natural products that are beneficial for human and livestock health. As one of the largest grown crops in the world, soybean (Glycine max) is widely used as human food and animal feed. Many cultivated soybeans with yellow seed coats lack PAs or anthocyanins, although some soybean cultivars have coloured seed coats that contain these compounds. Here, we analyse the transcriptional control of PA and anthocyanin biosynthesis in soybean. Ectopic expression of the transcription factors (TFs) GmTT2A, GmTT2B, GmMYB5A or R in soybean hairy roots induced the accumulation of PAs (primarily in phloem tissues) or anthocyanins and led to up-regulation of 1775, 856, 1411 and 1766 genes, respectively, several of which encode enzymes involved in PA biosynthesis. The genes regulated by GmTT2A and GmTT2B partially overlapped, suggesting conserved but potentially divergent roles for these two TFs in regulating PA accumulation in soybean. The two key enzymes anthocyanidin reductase and leucoanthocyanidin reductase were differentially upregulated, by GmTT2A/GmTT2B and GmMYB5A, respectively. Transgenic soybean plants overexpressing GmTT2B or MtLAP1 (a proven up-regulator of the upstream reactions for production of precursors for PA biosynthesis in legumes) showed increased accumulation of PAs and anthocyanins, respectively, associated with transcriptional reprogramming paralleling the RNA-seq data collected in soybean hairy roots. Collectively, our results show that engineered PA biosynthesis in soybean exhibits qualitative and spatial differences from the better-studied model systems Arabidopsis thaliana and Medicago truncatula, and suggest targets for engineering PAs in soybean plants. The COVID-19 pandemic has forced surgeons to adapt their standard procedures. The modifications introduced are designed to favour minimally invasive surgery. The positive results obtained with intracorporeal resection and anastomosis in the right colon and rectum prompt us to adapt these procedures to the left colon. We describe a 'don't touch the bowel' technique and outline the benefits to patients of the use of less surgically aggressive techniques and also to surgeons in terms of the lower emission of aerosols that might transmit the COVID-19 infection. This was an observational study of intracorporeal resection and anastomosis in left colectomy. We describe the technical details of intracorporeal resection, end-to-end stapled anastomosis and extraction of the specimen through mini-laparotomy in the ideal location. We present preliminary results of 17 patients with left-sided colonic pathologies, 15 neoplasia and two diverticular disease, who underwent four left hemicolectomies, six sigmoidectomies and seven high anterior resections. Median operating time was 186min (range 120-280). https://www.selleckchem.com/products/bms-265246.html No patient required conversion to extracorporeal laparoscopy or open surgery. Median hospital stay was 4.7days (range 3-12days). There was one case of anastomotic leak managed with conservative treatment. Intracorporeal resection and end-to-end anastomosis with the possibility of extraction of the specimen by a mini-laparotomy in the ideal location may present benefits and also adapts well to the conditions imposed by the COVID-19 pandemic. Future comparative studies are needed to demonstrate these benefits with respect to extracorporeal anastomosis.
