AI Article Synopsis

  • The controlled human infection model (CHIM) for enterotoxigenic Escherichia coli (ETEC) has helped identify ETEC as a major cause of acute watery diarrhea, improving understanding of the disease and immune responses.
  • Over a dozen ETEC strains have been tested, mimicking symptoms of natural infections, which is essential for evaluating vaccines and treatments.
  • Recent advancements in the CHIM technology, combined with omics-based approaches, are expected to enhance insights into host-pathogen interactions and support the creation of prevention strategies.

Article Abstract

The controlled human infection model (CHIM) for enterotoxigenic Escherichia coli (ETEC) has been instrumental in defining ETEC as a causative agent of acute watery diarrhea, providing insights into disease pathogenesis and resistance to illness, and enabling preliminary efficacy evaluations for numerous products including vaccines, immunoprophylactics, and drugs. Over a dozen strains have been evaluated to date, with a spectrum of clinical signs and symptoms that appear to replicate the clinical illness seen with naturally occurring ETEC. Recent advancements in the ETEC CHIM have enhanced the characterization of clinical, immunological, and microbiological outcomes. It is anticipated that omics-based technologies applied to ETEC CHIMs will continue to broaden our understanding of host-pathogen interactions and facilitate the development of primary and secondary prevention strategies.

A critical review on effects of artificial sweeteners on gut microbiota and gastrointestinal health.

J Sci Food Agric

January 2025

Food Science and Technology Program, Department of Life Sciences, BNU-HKBU United International College, Zhuhai, China.

Artificial sweeteners have emerged as popular alternatives to traditional sweeteners, driven by the growing concern over sugar consumption and its associated rise in obesity and metabolic disorders. Despite their widespread use, the safety and health implications of artificial sweeteners remain a topic of debate, with conflicting evidence contributing to uncertainty about their long-term effects. This review synthesizes current scientific evidence regarding the impact of artificial sweeteners on gut microbiota and gastrointestinal health.

Background: Poor acute postoperative pain control, coupled with the use of intravenous medications with a limited and unsafety efficacy spectrum, has led to new therapeutic alternative explorations to reduce adverse events while increasing its analgesic efficacy. There cannabinoids have been proposed as a useful control agent in post-surgical pain. Nevertheless, to date, there is no solid evidence to evaluate them.

Three-Dimensional CT for Preprocedural Planning of PCI for Ostial Right Coronary Artery Lesions: A Randomized Controlled Pilot Trial.

Circ Cardiovasc Interv

January 2025

Department of Cardiology, Ziekenhuis Oost-Limburg, Genk, Belgium (D.M.F.v.d.B., E.M.P., E.W., D.C., E.M., B.F., M.V., J.D., K.A.).

Background: Geographic stent-ostium mismatch is an important predictor of target lesion failure after percutaneous coronary intervention of an aorto-ostial right coronary artery lesion. Optimal visualization of the aorto-ostial plane is crucial for precise stent implantation at the level of the ostium. This study investigates whether preprocedural 3-dimensional computed tomography (3DCT), with determination of the optimal viewing angle, would allow for more precise stent implantation and reduce procedure time, contrast, and radiation dose.
