Objective: Parkinson's disease (PD) may be caused by an enteric neurotropic pathogen entering the brain through the vagal nerve, a process that may take over 20 years. We investigated the risk of PD in patients who underwent vagotomy and hypothesized that truncal vagotomy is associated with a protective effect, whereas superselective vagotomy has a minor effect.
Methods: We constructed cohorts of all patients in Denmark who underwent vagotomy during 1977-1995 and a matched general population cohort by linking Danish registries. We used Cox regression to compute hazard ratios (HRs) for PD and corresponding 95% confidence intervals (CIs), adjusting for potential confounders.
Results: Risk of PD was decreased in patients who underwent truncal (HR = 0.85; 95% CI = 0.56-1.27; follow-up of >20 years: HR = 0.58; 95% CI: 0.28-1.20) compared to superselective vagotomy. Risk of PD was also decreased after truncal vagotomy when compared to the general population cohort (overall adjusted HR = 0.85; 95% CI: 0.63-1.14; follow-up >20 years, adjusted HR = 0.53; 95% CI: 0.28-0.99). In patients who underwent superselective vagotomy, risk of PD was similar to the general population (HR = 1.09; 95% CI: 0.84-1.43; follow-up of >20 years: HR = 1.16; 95% CI: 0.80-1.70). Statistical precision of risk estimates was limited. Results were consistent after external adjustment for unmeasured confounding by smoking.
Interpretation: Full truncal vagotomy is associated with a decreased risk for subsequent PD, suggesting that the vagal nerve may be critically involved in the pathogenesis of PD.

Background: Increased glucagon levels are now recognized as a pathophysiological adaptation to counteract overnutrition in type 2 diabetes (T2D). This study aimed to elucidate the role of glucagon in peripheral nerve function in patients with T2D with different body mass indices (BMIs).
Methods: We consecutively enrolled 174 individuals with T2D and obesity (T2D/OB, BMI ≥ 28 kg/m), and 480 individuals with T2D and nonobesity (T2D/non-OB, BMI < 28 kg/m), all of whom underwent oral glucose tolerance tests to determine the area under the curve for glucagon (AUC).

Background: Hepatic glycogen storage diseases (GSD) are inborn errors of metabolism with abnormal storage or utilization of glycogen, a complex disease with significant genetic heterogeneity and similar clinical manifestations. This study aimed to describe the gastrointestinal symptoms and endoscopic features of hepatic GSD, including types Ia, Ib, III, VI, and IX, to provide evidence for etiology and treatment.
Methods: A national cohort survey questionnaire was distributed to patients diagnosed with GSD type Ia, Ib, III, VI, and IX through genetic testing or their parents in mainland China in May 2022.
Self-administered active versus sham acupressure for diarrhea predominant irritable bowel syndrome: a nurse-led randomized clinical trial.
BMC Nurs

Medical Surgical Nursing Department, Faculty of Nursing, Alexandria University, Alexandria, Egypt.
Background: Diarrhea-predominant irritable bowel syndrome (IBS-D) significantly impacts patients' quality of life, with existing treatments offering limited relief. Self-administered acupressure presents a potential non-invasive, cost-effective treatment option that could alleviate symptoms and enhance health outcomes in these patients.
Aim: This randomized controlled trial aimed to evaluate the effect of active acupressure compared to sham acupressure on primary and secondary outcomes among IBS-D patients.

Background: It is crucial to identify post-operative patients with HPV infection who are at high risk for residual/recurrent disease. This study aimed to evaluate the association between HPV integration and clinical outcomes in HPV-positive women after cervical conization, as well as to identify HPV integration breakpoints.
Methods: This retrospective study analyzed data of 791 women who underwent cervical conization for cervical intraepithelial neoplasia grades 2-3 (CIN2-3) between September 2019 and September 2023, sourced from the Fujian and Hubei cervical lesion screening cohorts.
