Incidence and Clinical Course of Post-infectious Irritable Bowel Syndrome in Patients Admitted to University Hospitals: 1-year Prospective Follow-up Study.

Background/aims: Post-infectious irritable bowel syndrome (PI-IBS) is characterized by chronic gastrointestinal symptoms that arise following an episode of infectious enteritis. The incidence rates vary, ranging from 5% to 32% and the risk factors are not well known. We aim to investigate the incidence and risk factors of PI-IBS in enteritis patients admitted to university hospitals in Korea.

Challenges and global trends in combating enteric hepatitis.

Enteric hepatitis, represented by the hepatitis A virus (HAV) and hepatitis E virus (HEV), remains a significant global public health concern. While much progress has been made, many aspects of the biology and pathophysiology of HAV and HEV are still not fully understood. One of the major challenges is the absence of a reliable system for virus replication.

Ultrasonographic features of feline gastrointestinal eosinophilic sclerosing fibroplasia on initial presentation and during follow-up.

The aim of this study is to describe the ultrasonographic features of feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) before histological diagnosis and during follow-up after surgical excision and/or medical treatment. This multicentric retrospective case series study includes medical records of cats diagnosed histologically, which had an ultrasound before diagnosis and a minimum of one follow-up ultrasound at least 4 weeks after treatment. Thirty cats were included in the study.

The effects of rain and drought on incidence of enteric disease in Pennsylvania (2010-2019).

Background: Campylobacter, nontyphoidal Salmonella, Cryptosporidium, and Giardia cause an estimated 1 million cases of domestically acquired waterborne diseases annually in the United States. Acute symptoms can include diarrhea and vomiting; however, these illnesses can result in longer term complications such as reactive arthritis, Guillan Barré syndrome and death, particularly in immunocompromised individuals. Precipitation and drought can plausibly increase the risk of enteric infections, but consensus in the literature is lacking.

Pathogens and Antimicrobial Resistance Genes in Household Environments: A Study of Soil Floors and Cow Dung in Rural Bangladesh.

In low- and middle-income countries, living in homes with soil floors and animal cohabitation may expose children to fecal organisms, increasing risk of enteric and antimicrobial-resistant infections. Our objective was to understand whether cow cohabitation in homes with soil floors in rural Bangladesh contributed to the presence and diversity of potential pathogens and antimicrobial resistance genes (ARGs) in the home. In 10 randomly selected households in rural Sirajganj District, we sampled floor soil and cow dung, which is commonly used as sealant in soil floors.

Protocol for gene knockdown using siRNA in organotypic cultures of murine gastric muscle.

Understanding the molecular interactions within the neuromuscular apparatus in the stomach is crucial for understanding their role in maintaining interstitial cells, such as the interstitial cells of Cajal (ICC), smooth muscle, and enteric neurons, as well as their contribution to gastric motility in both healthy and diseased states. Disruptions of these systems can lead to various gastric motor disorders and diseases, making it essential to explore their functions in detail. We herein present a protocol for gene knockdown using small interfering RNA (siRNAs) in organotypic culture.

A stand-alone and point-of-care electrochemical immuno-device for Salmonella typhimurium testing.

The rapid development of accurate and point-of-care diagnostic tools for foodborne diseases has made a massive impact in global health. Salmonella typhimurium (S. typhimurium) exemplifies an enteric pathogen, being a gram-negative bacteria responsible for several gastrointestinal and systemic illnesses.

Epidemiology of Multidrug-Resistant Typhi and Paratyphi Isolated From Stool Culture.

Enteric fever is a significant health problem in developing countries caused by serovars Typhi and Paratyphi. Unfortunately, the burden of the disease remains high not only because of the complications related to the disease but also, especially, because of the spread of the strains of resistant to antibiotics. The aim of the present study was to evaluate the antibiotic resistance patterns of Typhi and Paratyphi clinical isolates as well as the risk factors associated with infection.

A mouse model for the study of diet-induced changes in intestinal microbiome composition on renal calcium oxalate crystal formation.

Currently available animal models for calcium oxalate kidney stones are limited in their translational potential. Particularly with increasing interest in gut microbiota involvement in kidney stone disease, there are limited animal models which can be used. As such, we have developed a novel diet-induced hyperoxaluria murine model which addresses some of the shortcomings of other currently available models.

Gastric emptying time and its correlation with cardiac MIBG in body-first and brain-first subtype Parkinson's disease.

Introduction: Recently, "body-first" and "brain-first" subtype in Parkinson's disease (PD) was proposed based on the propagation of α-synuclein. In isolated RBD considered as a premotor stage of body-first PD, α-synuclein was supposed to originate in the enteric nervous system and spreads via autonomic nervous system. Therefore, we hypothesized that body-first PD is more likely to have a delayed gastric emptying time and reduced cardiac sympathetic denervation.

Specific gFET-Based Aptasensors for Monitoring of Microbiome Quality: Quantification of the Enteric Health-Relevant Bacterium Roseburia Intestinalis.

Roseburia intestinalis, enriched in the gut, is closely associated with obesity, intestinal inflammation, and other diseases. A novel detection method for R. intestinalis to replace the commonly used 16S rRNA sequencing technique is aim to developed, thus enabling real-time and low-cost monitoring of gut microbiota.

Quantitative microbial risk assessment of acute gastrointestinal illness attributable to freshwater recreation in Ontario.

Objectives: The burden of disease associated with acute gastrointestinal illness (AGI) in Canada is estimated to be ~ 20 million cases/year. One known risk factor for developing AGI is recreation in freshwater bodies such as lakes. The proportion of cases attributable to freshwater recreation in Canada, however, is currently unknown.

Genomic perspective on the bacillus causing paratyphoid B fever.

Paratyphoid B fever (PTB) is caused by an invasive lineage (phylogroup 1, PG1) of Salmonella enterica serotype Paratyphi B (SPB). However, little was known about the global population structure, geographic distribution, and evolution of this pathogen. Here, we report a whole-genome analysis of 568 historical and contemporary SPB PG1 isolates, obtained globally, between 1898 and 2021.

TNBS colitis induces architectural changes and alpha-synuclein overexpression in mouse distal colon: A morphological study.

Alpha-synuclein (α-syn) is widely expressed in presynaptic neuron terminals, and its structural alterations play an important role in the pathogenesis of Parkinson's disease (PD). Aggregated α-syn has been found in brain, in the peripheral nerves of the enteric nervous system (ENS) and in the intestinal neuroendocrine cells during synucleinopathies and inflammatory bowel disorders. In the present study, we evaluated the histomorphological features of murine colon with 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis, a common model of colitis.

Association between precipitation events, drought, and animal operations with infections in the Southwest US, 2009-2021.

Background: Temperature and precipitation have previously been associated with infections. The association between salmonellosis and precipitation might be explained by antecedent drought conditions; however, few studies have explored this effect.

Methods: Using an ecological study design with public health surveillance, meteorological (total precipitation [inches], temperature [average °F], Palmer Drought Severity Index [PDSI, category]), and livestock data we explored the association between precipitation and infections reported in 127/141 counties from 2009 to 2021 in the Southwest, US and determined how this association was modified by antecedent drought.

Protein-losing enteropathy as the first presentation of systemic lupus erythematosus the first case reported in Palestine with systemic review.

Introduction: Systemic lupus erythematosus is a chronic inflammatory disease affecting women, causing gastrointestinal issues like acute pancreatitis, esophagitis, and protein-losing enteropathy. Protein loss is uncommon, but a case study shows protein-losing enteropathy as a first sign.

Importance: Protein-losing enteropathy (PLE) is a rare gastrointestinal manifestation of SLE, often seen years before diagnosis.

Lineage-specific intersection of endothelin and GDNF signaling in enteric nervous system development.

Two major ligand-receptor signaling axes - endothelin Edn3 and its receptor Ednrb, and glial-derived neurotrophic factor (GDNF) and its receptor Ret - are required for migration of enteric nervous system (ENS) progenitors to the hindgut. Mutations in either component cause colonic aganglionosis, also called Hirschsprung disease. Here, we have used Wnt1Cre and Pax2Cre in mice to show that these driver lines label distinct ENS lineages during progenitor migration and in their terminal hindgut fates.
