Objective:To explore the symptoms of Ménière′s disease patients and their impact on quality of life.Methods:A cross-sectional study was conducted, consecutively enrolling patients of Ménière′s disease who visited the Otolaryngology Clinic at the Eye & ENT Hospital of Fudan University from October 2014 to December 2022. The Chinese version of the Ménière′s Disease Outcomes Questionnaire (MDOQ) and a Ménière′s disease-specific symptom checklist were utilized for assessment. SPSS 25.0 software was employed to perform multiple linear regression analysis to determine the impact of Ménière′s disease symptoms on patients′ quality of life.Results:A total of 790 patients with a definitive diagnosis of Ménière′s disease who met the inclusion and exclusion criteria were analyzed. The cohort comprised 418 males and 372 females, with a mean age of (54.8±13.1) years and a diagnosis duration ranging from 0 to 72 months, with a median of 3 months. The total score of the Chinese MDOQ was 61.0±12.0. The symptomatic presentations of the enrolled patients included hearing changes, tinnitus, aural fullness, drop attacks, vertigo episodes, visual instability, dizziness, and headache. Multiple linear regression analysis revealed that age, tinnitus, aural fullness, frequency of drop attacks, visual instability, dizziness, and headache were significant factors affecting the quality of life in Ménière′s disease patients ( F=145.50, P<0.05). Conclusions:The quality of life in Ménière′s disease patients requires improvement. Attention to the specific symptoms of Ménière′s disease and their impact on patients′ quality of life, along with targeted symptom interventions based on these findings, will be a focal point in future disease management.

Objective:To understand the incidence of adverse pregnancy outcome in HIV-infected pregnant women and influencing factors in China and provide reference for the improvement of the health status of HIV-infected pregnant women and their newborns.Methods:Based on a mother-child cohort of HIV-infected pregnant women and children (PMTCT-MC-2005) established in Guangxi Zhuang Autonomous Region, Yunnan Province and Xinjiang Uygur Autonomous Region, this study enrolled pregnant women with or without HIV infection as study subjects from January 2017 to June 2023, a total of 1 646 pregnant women (558 HIV-infected and 1 088 HIV-uninfected) were included, and 34 cases with missing data were excluded. The χ2 test was used to analyze the difference in the incidence adverse pregnancy outcome between two groups, and used logistic regression model to identify the influencing factors of adverse pregnancy outcome in HIV-infected pregnant women. Results:A total of 1 612 pregnant women were included in the study, in whom 541 were infected with HIV and 1 071 were not infected with HIV. The incidence of adverse pregnancy outcome was 18.8% (303/1 612), the incidence of adverse pregnancy outcome was 33.1% (179/541) in the HIV-infected pregnant women and 11.6% (124/1 071) in the pregnant women without HIV infection. The results of multivariable logistic regression analysis showed that the influencing factors of adverse pregnancy outcome were age <35 years at delivery (a OR=0.64, 95% CI: 0.43-0.95) compared with the age ≥35 years and the duration of antiviral treatment over 10 years (a OR=0.43, 95% CI: 0.23-0.79) compared with less than one year. Conclusions:The incidence of adverse pregnancy outcome in HIV-infected pregnant women was high in some regions of China during 2017-2023. It is necessary for HIV-infected women to get pregnancy at appropriate time based on antiretroviral treatment effect and strengthen self-care to reduce the incidence of adverse pregnancy outcome.

Mesenchymal stem cells (MSCs) have been widely used in the treatment of various autoimmune and inflammation-related diseases due to their potent immunomodulatory properties. Several studies have demonstrated that MSC-mediated immunomodulation is complex and bidirectional, with the in vivo microenvironment influencing the direction of this modulation. Indoleamine-2,3-dioxygenase (IDO), an immunosuppressive factor, has been identified as a key "switch" in the immunomodulatory role of MSCs. In this review, we explore how IDO functions as a critical regulator of MSC immunoregulatory plasticity. We delve into the mechanisms by which changes in IDO expression affect the function of various immune cells, summarize relevant research and clinical advances regarding the role of IDO expression in MSC-based therapies for various diseases, and discuss potential therapeutic strategies that target IDO to enhance the stability of MSC therapeutic effects. This provides a theoretical foundation for optimizing MSCs as safer and more effective clinical therapeutic agents.

Objective:To investigate the status of psychological distress, self-compassion, and self-management behaviors among patients with type 2 diabetes mellitus (T2DM), and explore the mediating role of self-compassion in the relationship between diabetes distress and self-management behaviors, and to provide a theoretical basis for the psychological intervention of patients with T2DM.Methods:A convenience sampling method was adopted to select 221 patients with T2DM hospitalized in the Department of Endocrinology and Metabolism, the First Hospital of China Medical University from November 2023 to April 2024. The General Information Form, the Diabetes Distress Scale-17, the Self-Compassion Scale and the Summary of Diabetes Self-Care Activity were utilized for investigation. A structural equation model was constructed with AMOS 24.0 to analyze the relationships among psychological distress, self-compassion, and self-management behaviors, and the mediating effect of self-compassion was tested using the Bootstrap method.Results:A total of 221 patients with T2DM were included, including 138 males and 83 females, aged (54.52 ±10.42) years old. The total score of psychological distress of patients with T2DM was (34.55 ± 18.82) points, the total score of self-compassion was (94.22 ± 26.04) points, and the total score of self-management behavior was (40.81 ± 22.64) points. Psychological distress in T2DM patients was significantly negatively correlated with both self-compassion ( r=-0.850, P<0.01) and self-management behaviors ( r=-0.736, P<0.01). In contrast, self-compassion was significantly positively correlated with self-management behaviors ( r=0.743, P<0.01). Self-compassion partially mediated the relationship between diabetes-related psychological distress and self-management behaviors, with a mediation effect size of -0.456. Conclusions:Psychological distress among T2DM patients is at a moderate level, and their self-management behaviors require urgent improvement. Psychological distress not only directly impacts self-management behaviors but also indirectly influences them through self-compassion. Healthcare professionals should prioritize enhancing patients′ self-compassion levels to mitigate the negative effects of psychological distress on their health behaviors.

Objective: To investigate the epidemiological characteristics of influenza outbreaks in Zhejiang Province from 2013 to 2022, so as to provide insights into influenza prevention and control. Methods: Data pertaining to influenza outbreaks reported in Zhejiang Province from 2013 to 2022 were collected from National Influenza Surveillance System in China, including time, region, cases and pathogen types of influenza outbreaks. The temporal, spatial and pathogen distribution of influenza outbreaks were analyzed using a descriptive epidemiological method. Results: A total of 577 influenza outbreaks involving 448 698 individuals were reported in Zhejiang Province from 2013 to 2022, and the overall attack rate was 5.34% (23 974 cases), with no death reported. The lowest attack rate of influenza was 0.26%, and the highest was 80.00%, with a median attack rate of 10.89% (interquartile range, 24.26%). The outbreak had the shortest duration of 1.00 day, and the longest duration of 59.00 days, with a median duration of 9.00 (interquartile range, 11.00) days. There were 387 influenza outbreaks that occurred between November and January of the following year (67.07%), and the three highest numbers of outbreaks were reported in Hangzhou City (310 outbreaks), Wenzhou City (51 outbreaks) and Jinhua City (46 outbreaks). There were 395 outbreaks reported in urban regions (68.46%), 93 in counties and townships (16.12%) and 89 in rural regions (15.42%), and influenza outbreaks predominantly occurred in primary schools (487 outbreaks, 84.40%). In addition, the types of pathogens were alternately prevalent, with influenza B virus (241 outbreaks, 41.77%) and A/H3N2 virus (232 outbreaks, 40.21%) as predominant subtypes. Conclusions Influenza outbreaks mainly occurred in winter in Zhejiang Province from 2013 to 2022, and primary schools were main places of influenza outbreaks, while influenza B virus and A/H3N2 virus were predominant subtypes. It is necessary to reinforce the surveillance and report of influenza-like illness in schools and improve the coverage of influenza vaccination to prevent influenza outbreaks.
