Risk factors and surgical outcomes in pediatric patients with congenital heart disease and ischemic colitis.

Introduction: This study investigates risk factors and surgical outcomes in pediatric patients with congenital heart defects (CHD) who develop ischemic colitis (IC). Previous research indicates a higher IC risk in very low birth weight neonates with CHD.

Methods: A retrospective analysis compared an IC-CHD group to a CHD-only group.

Hypoxia-Inducible Factor-1α Modulates the Toll-Like Receptor 4/Nuclear Factor Kappa B Signaling Pathway in Experimental Necrotizing Enterocolitis.

Necrotizing enterocolitis (NEC) is a devastating disease observed in premature infants, characterized by intestinal ischemia and inflammation. Hypoxia-inducible factor-1 alpha (HIF-1α), a master regulator of the cellular response to hypoxia and ischemia, plays a critical role in NEC pathogenesis. However, the precise mechanisms by which HIF-1α influences the intestines in NEC remain poorly understood.

Acute Torticollis Reaction Following Metoclopramide Use in a Pediatric Patient: A Comprehensive Case Report and Appraisal of Current Knowledge.

Dopamine receptor antagonists like metoclopramide are frequently used in a variety of clinical contexts to treat gastrointestinal disorders and control nausea and vomiting. However, it is associated with a high incidence of extrapyramidal side effects (EPS) in children, including dystonic movements and torticollis. This is the instance of a 9-year-old girl who developed abnormal movements of the neck and tongue, along with torticollis, within 48 hours of receiving intravenous metoclopramide for gastroenteritis.

Ferroptosis and its impact on common diseases.

Ferroptosis is a novel form of programmed cell death characterized by iron accumulation, lipid peroxidation, and a decline in antioxidant capacity, all of which are regulated by gene expression. The onset of numerous diseases is closely associated with ferroptosis. Common diseases affect a large population, reduce the quality of life, and impose an increased burden on the healthcare system.

Acquired methemoglobinemia in infancy secondary to diarrhea: a case report.

Methemoglobinemia (MetHb) is a life-threatening condition that reduces the oxygen-carrying ability of hemoglobin. Acquired methemoglobinemia usually results from exposure to specific oxidizing agents. Symptoms and complications depend on the MetHb level, which can sometimes be fatal.

Biotechnological Interventions for the Production of Subunit Vaccines Against Group A Rotavirus.

Group A rotavirus (RVA) is a major cause of severe gastroenteritis in infants and young children globally, despite the availability of live-attenuated vaccines. Challenges such as limited efficacy in low-income regions, safety concerns for immunocompromised individuals, and cold-chain dependency necessitate alternative vaccine strategies. Subunit vaccines, which use specific viral proteins to elicit immunity, provide a safer and more adaptable approach.

Short-term postoperative complications in preterm neonates with surgical necrotizing enterocolitis: a multicenter retrospective cohort study.

Background: Over half of preterm neonates with necrotizing enterocolitis (NEC) require surgery, making it essential to understand short-term postoperative outcomes and complication rates. Therefore, this study aimed to provide an overview of 30-day postoperative complications for NEC. Secondary, risk factors for minor and major short-term postoperative complications were identified.

RNA-dependent RNA polymerase of predominant human norovirus forms liquid-liquid phase condensates as viral replication factories.

Many viral proteins form biomolecular condensates via liquid-liquid phase separation (LLPS) to support viral replication and evade host antiviral responses, and thus, they are potential targets for designing antivirals. In the case of nonenveloped positive-sense RNA viruses, forming such condensates for viral replication is unclear and less understood. Human noroviruses (HuNoVs) are positive-sense RNA viruses that cause epidemic and sporadic gastroenteritis worldwide.

Eleven Grand Challenges for Inflammatory Bowel Disease Genetics and Genomics.

The past 2 decades have witnessed extraordinary advances in our understanding of the genetic factors influencing inflammatory bowel disease (IBD), providing a foundation for the approaching era of genomic medicine. On behalf of the NIDDK IBD Genetics Consortium, we herein survey 11 grand challenges for the field as it embarks on the next 2 decades of research utilizing integrative genomic and systems biology approaches. These involve elucidation of the genetic architecture of IBD (how it compares across populations, the role of rare variants, and prospects of polygenic risk scores), in-depth cellular and molecular characterization (fine-mapping causal variants, cellular contributions to pathology, molecular pathways, interactions with environmental exposures, and advanced organoid models), and applications in personalized medicine (unmet medical needs, working toward molecular nosology, and precision therapeutics).

Acute Abdominal Pain in Children: Evaluation and Management.

Acute abdominal pain in children is a common presentation in the clinic and emergency department settings and accounts for up to 10% of childhood emergency department visits. Determining the appropriate disposition of abdominal pain in children can be challenging. The differential diagnosis of acute abdominal pain, including gastroenteritis, constipation, urinary tract infection, acute appendicitis, tubo-ovarian abscess, testicular torsion, and volvulus, and the diagnostic approach vary by age.

A Case of Refractory Kawasaki Disease With Yersinia pseudotuberculosis Infection Successfully Treated With Cefotaxime Following Immunosuppressive Therapy.

Kawasaki disease (KD) is a vasculitis mainly affecting children under five, with symptoms such as persistent fever, rash, red lips, strawberry tongue, conjunctivitis, and swollen hands and feet. Diagnosis is based on a fever lasting over five days plus at least four of these symptoms. Treatment includes intravenous immunoglobulin (IVIG) and aspirin to reduce complications, especially coronary artery issues.

Time-efficient strategies in human iPS cell-derived pancreatic progenitor differentiation and cryopreservation: advancing towards practical applications.

Background: Differentiation of patient-specific induced pluripotent stem cells (iPS) helps researchers to study the individual sensibility to drugs. However, differentiation protocols are time-consuming, and not all tissues have been studied. Few works are available regarding pancreatic exocrine differentiation of iPS cells, and little is known on culturing and cryopreserving these cells.

Eosinophilic duodenitis misdiagnosed as acute pancreatitis in a child: a case report.

Background: Eosinophilic Gastrointestinal Disorders beyond Eosinophilic Esophagitis (non-EoE EGIDs) are chronic rare inflammatory disorders characterized by eosinophilic infiltration of the gastrointestinal (GI) tract.

Case Presentation: We report the first pediatric case of eosinophilic duodenitis (one type of the non-EoE EGIDs) with concomitant pancreatic reaction that was misdiagnosed as acute pancreatitis (AP). A 13-year-old girl was admitted to our hospital for a week of abdominal distension, vomiting, and epigastric pain that worsened recently.

Background/objectives: Identifying nutritional interventions in extremely low-birth-weight (ELBW) infants (<1000 g) that are associated with favorable clinical outcomes is important. Delayed enteral feeding initiation (>3 days) has been associated with increased odds of developing morbidity. Therefore, the aim of this study is to evaluate the relationship between hour of life at enteral feeding initiation and associated clinical outcomes.

Role of Protein Tyrosine Phosphatases in Inflammatory Bowel Disease, Celiac Disease and Diabetes: Focus on the Intestinal Mucosa.

Protein tyrosine phosphatases (PTPs) are a family of enzymes essential for numerous cellular processes, such as cell growth, inflammation, differentiation, immune-mediated responses and oncogenic transformation. The aim of this review is to review the literature concerning the role of several PTPs-PTPN22, PTPN2, PTPN6, PTPN11, PTPσ, DUSP2, DUSP6 and PTPRK-at the level of the intestinal mucosa in inflammatory bowel disease (IBD), celiac disease (CeD) and type 1 diabetes (T1D) in both in vitro and in vivo models. The results revealed shared features, at the level of the intestinal mucosa, between these diseases characterized by alterations of different biological processes, such as proliferation, autoimmunity, cell death, autophagy and inflammation.

The impact of multiplex nested gastrointestinal PCR panel in children with gastroenteridis requiring pediatric infectious disease consultation.

Unlabelled: Infectious gastroenteritis is an important cause of morbidity and mortality, especially in nations with middle and low incomes. In a pediatric gastroenteritis patient, the aim was to determine the therapeutic impact of using the Gastrointestinal Panel in our clinical practice. A single-center retrospective study was designed to evaluate children who were admitted to the hospital for gastroenteritis and had a gastrointestinal panel between August 2021 and January 2024.

Eosinophilic gastroenteritis with hemorrhagic ascites: a case report.

Eosinophilic gastroenteritis (EGE) is an inflammatory disease characterized by a significant increase in eosinophils. EGE itself is rare, and cases with clinical manifestations of hemorrhagic ascites are even rarer, which undoubtedly increases the risk of misdiagnosis. Given this, this study reports a rare case of pediatric EGE presenting with paroxysmal abdominal pain without apparent cause, accompanied by acute tonsillitis and mesenteric lymphadenitis, suggesting a possible intestinal infection.
