Article Abstract
Background: Assessing the severity of constipation in patients is important for tailoring treatment plans and monitoring outcomes. However, validated assessment tools for constipation severity are limited in China.
Objective: This study aimed to evaluate the psychometric properties of the Chinese version of the Constipation Severity Index (CSI).
Methods: A cross-sectional survey was conducted in two tertiary hospitals in China. A total of 621 patients meeting the diagnostic criteria for constipation were enrolled. The scale's reliability and validity were assessed using Content Validity Index (CVI), Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), internal consistency, and test-retest reliability.
Results: The expert-rated Item-level Content Validity Index (I-CVI) was 0.90. EFA revealed a three-factor structure comprising 16 items, accounting for 71.81% of the total variance. CFA results suggested acceptable model fit (χ2 = 257.711, df = 96, < 0.001; CFI = 0.965; TLI = 0.956; RMSEA = 0.074, 90% CI: 0.063-0.085; SRMR = 0.047). The scale demonstrated good internal consistency (Cronbach's alpha = 0.936, McDonald's Omega = 0.937).
Conclusion: This study provides preliminary evidence for the reliability and validity of the Chinese version of the CSI. While the initial results are promising, further research is needed to validate its applicability in various clinical settings and patient populations. The CSI may potentially serve as a useful tool for assessing constipation severity in Chinese patients, but additional validation studies are necessary before its widespread clinical application.

Intractable functional constipation (IFC), a severe form of chronic constipation characterized by slow transit and resistance to conventional treatments, posed a significant clinical challenge. Here, we identified Lactococcus formosensis (Lf), a Gram-positive bacterium prevalent in IFC patients, as a novel contributor to intestinal motility impairment. Clinically, IFC patients exhibited increased colonic mucosal colonization of Lf and significant myenteric neuronal loss and pyroptosis, particularly in excitatory choline acetyltransferase (ChAT) neurons, but not inhibitory neuronal nitric oxide synthase (nNOS) neurons.

Summary: Hypercalcemia is a prevalent electrolyte disturbance commonly associated with primary hyperparathyroidism, cancer, or medication adverse effects. Thiazide diuretics reduce urinary calcium excretion, increasing calcium reabsorption and hypercalcemia. Tirzepatide, a dual GIP and GLP-1 receptor agonist, is increasingly used for type 2 diabetes and obesity.

Suzetrigine is a novel non-opioid analgesic for treating moderate to severe acute pain. Clinical trials for postoperative pain demonstrated that the most common side effects were headache and constipation. Since it became commercially available in March of 2025, there have been no case reports of unanticipated problems.

Background: Autonomic symptoms are among the most important factors determining the quality of life in patients with Parkinson's disease (PD). This study aimed to assess the profile of autonomic dysfunction symptoms in three groups of patients with genetic PD, carrying mutations in , , and genes, compared with subjects with sporadic PD.
Methods: This case-control observational secondary analysis of prospectively collected data was performed on 742 patients (485 in the sporadic group, 165 in the LRRK2 group, 85 in the GBA group, and nine in the PRKN group).

Background: There is little data on contemporary patterns of antiemetic use or women's experiences when using such agents in the treatment of severe nausea and vomiting of pregnancy (NVP) or hyperemesis gravidarum (HG).
Methods: Online, national survey of Australian women who were currently or had previously experienced severe NVP or HG, distributed through the HG consumer group, Hyperemesis Australia between July and September 2020.
Results: There were a total of 289 respondents with a mean age of 33 years, of which 38% were currently pregnant.
