Purpose: Intussusception is one of the most common causes of acute abdominal emergencies in infants and preschool children. Loss of intestine viability is the most serious complication of intussusception. This study aimed to investigate the risk factors for loss of intestine viability in pediatric intussusception cases among children.
Methods: Data were collected for operative pediatric intussusception cases (N = 316) from medical records of 5,537 hospitalized children due to intussusception between June 2009 and May 2014 in a pediatric surgery department of an academic teaching hospital in China. Seventy-six patients (24.1 %) of the operated intussusception cases had complication of loss intestine viability.
Results: Pediatric intussusception cases with loss of intestine viability and without loss of intestine viability were similar in terms of their age, malformation and season of admission. The median time of the duration from onset of symptoms to operative treatment was 23 h (range 3-90 h). The loss of intestine viability group of the intussusception cases was significantly associated with longer length of history (P = 0.000). Receiver operating characteristic curve analysis for length of history showed that the optimal ratio of sensitivity (0.70) and specificity (0.73) was calculated for the length of history longer than 27.5 h regarding loss of intestine viability of intussusception. In addition, the risk of loss of intestine viability was higher for female (31 %) than for male (20.8 %) (P = 0.049). The loss of intestine viability rate was also significantly higher in ileo-ileal intussusception cases than that of the other types (P = 0.033). However, there is no difference among the other groups.
Conclusion: The result of our risk factor analysis for loss of intestine viability in pediatric intussusception cases may help develop a predictability index to prevent the complication to happen. Further prospective studies are required to confirm our findings.

Purpose: Locally advanced colorectal tumors frequently invade adjacent organs, particularly the urinary bladder in the sigmoid colon and upper rectum, complicating multivisceral resections. This study compared postoperative outcomes of partial cystectomy (PC) and total cystectomy (TC) in patients with locally advanced colorectal cancer.
Methods: A systematic review was conducted in PubMed, Scopus, Central Register of Clinical Trials, and Web of Science for studies published up to November 2024.

Ulcerative colitis (UC) is an inflammatory disease of the intestinal mucosa, and its incidence is steadily increasing worldwide. As a traditional Chinese medicinal insect, has been broadly utilized in clinical practice to treat wound healing. The tryptophan (Trp), tryptamine (Try), and 1,2,3,4-tetrahydrogen-β-carboline-3-carboxylic acid (Thcc) identified from concentrated ethanol-extract liquid (PACEL) exhibit significant cell proliferation-promoting and anti-inflammatory effects in the treatment of UC, but the mechanism involved remains obscure.

Balanced self-renewal and differentiation of stem cells are crucial for maintaining tissue homeostasis, but the underlying mechanisms of this process remain poorly understood. Here, from an RNA interference (RNAi) screen in adult Drosophila intestinal stem cells (ISCs), we identify a factor, Pax, which is orthologous to mammalian PXN, coordinates the proliferation and differentiation of ISCs during both normal homeostasis and injury-induced midgut regeneration in Drosophila. Loss of Pax promotes ISC proliferation while suppressing its differentiation into absorptive enterocytes (ECs).

Chronic liver disease (CLD) has massive systemic repercussions including major impacts on the body's immune system. Abnormalities in phenotype, function and numbers of various immune cell subsets have been established by a large number of clinical and pre-clinical studies. The loss of essential immune functions renders CLD-patients exceptionally susceptible to bacterial and viral infections and also impairs the efficacy of vaccination.

Proper regulation of intestinal permeability is essential for maintaining the integrity of the intestinal mucosal barrier. An abnormal increase in permeability can significantly contribute to the onset and progression of various diseases, including autoimmune disorders, metabolic conditions, allergies, and inflammatory bowel diseases. The potential connection between intestinal permeability and maternal health during pregnancy is increasingly recognized, yet a comprehensive review remains lacking.
