The peripheral neuropathy Guillain-Barré Syndrome can follow Campylobacter jejuni infection when outer core lipooligosaccharides induce production of neurotoxic anti-ganglioside antibodies. We hypothesized that gut microbiota depletion with an antibiotic would increase C. jejuni colonization, severity of gastroenteritis, and GBS. Microbiota depletion increased C. jejuni colonization, invasion, and colitis with Type 1/17 T cells in gut lamina propria. It also stimulated Type 1/17 anti-C. jejuni and -antiganglioside-antibodies, Type 2 anti-C. jejuni and -antiganglioside antibodies, and neurologic phenotypes. Results indicate that both C. jejuni strain and gut microbiota affect development of inflammation and GBS and suggest that probiotics following C. jejuni infection may ameliorate inflammation and autoimmune disease.

Development and validation of a preoperative nomogram for predicting gallbladder adenoma.

Surg Endosc

January 2025

Department of Hepatopancreatobiliary Surgery, The Second Affiliated Hospital of Kunming Medical University, 374 Dianmian Avenue, Wuhua District, Kunming, 650106, Yunnan, People's Republic of China.

Background: Gallbladder cholesterol polyp (GCP) and gallbladder adenoma (GA) are easily confused in clinical diagnosis. This study aims to establish a nomogram prediction model for preoperative prediction of the risk of GA patients.

Study Design: We retrospectively collected clinical data of GCP or GA patients who underwent laparoscopic cholecystectomy (LC) between January 2020 and April 2023.

Objectives: To identify the diagnostic criteria for metabolic dysfunction-associated steatotic liver disease (MASLD) related to liver fibrosis and to characterize patients with cryptogenic steatotic liver disease (SLD) (non-MASLD) among those previously diagnosed with nonalcoholic fatty liver disease (NAFLD).

Methods: This multicenter retrospective study included 511 patients diagnosed with NAFLD via liver biopsy, and the prevalence of MASLD was assessed based on the diagnostic criteria. Patients were divided into those who met the MASLD criteria and those who did not, and the characteristics of advanced fibrosis and associated cardiometabolic factors were evaluated.

A nationwide registry-based cohort study of the association between childhood dental caries and gingivitis with type 2 diabetes in adulthood.

Acta Diabetol

January 2025

Section for Clinical Oral Microbiology, Department of Odontology, Faculty of Health and Medical Sciences, University of Copenhagen, Nørre Allé 20, 2200, Copenhagen, Denmark.

Background: Evidence suggests a bidirectional relationship between oral health status and type 2 diabetes (T2D) in adults. Studies on associations between childhood oral health and T2D in adulthood are lacking.

Methods: This is a nationwide Danish registry-based cohort study of individuals born between 1963 and 1972, having at least one registration in the National Child Odontology Registry between 1972 and 1987 (n = 627,758).

TERTp Mutation and its Prognostic Value in Glioma Patients Under the 2021 WHO Classification: A Real-World Study.

Cancer Med

January 2025

Department of Neurosurgery, Center for Malignant Brain Tumors, National Glioma MDT Alliance, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Background: The 2021 WHO Classification of Central Nervous System Tumors introduces more molecular markers for glioma reclassification, including TERT promoter (TERTp) mutation as a key feature in glioblastoma diagnosis.

Aims: Given the changes in the entities included in each subtype under the new classification, this research investigated the distribution, prognostic value, and correlations with other molecular alterations of TERTp mutation in different subgroups under this latest classification.

Methods: All glioma patients admitted to Peking Union Medical College Hospital for surgical resection or biopsy from 2011 to 2022 were included.

Purpose: To systematically review the evidence investigating the implementation of cardiorespiratory (CR) training in adults following a stroke and to understand how interventions are prescribed to address cardiorespiratory fitness (CRF).

Methods: Medline, CINAHL, EMBASE, EMCARE, Scopus, PEDro and ProQuest were searched from inception until January 2024. Inclusion criteria were studies that included adults following a stroke, investigated CR training interventions and used standardised CRF assessments.
