Objective: To determine the distribution of anti-hepatitis E virus (HEV) IgG antibody and anti-human papilloma virus (HPV) IgG antibody among female residents of Xinmi and investigate the risk factors of HEV infection.

Methods: A questionnaire was used to collect data on the demographic characteristics and suspected risk factors of HEV infection, including behavioral habits. All questionnaire responders also provided peripheral blood samples for investigation by enzyme-linked immunosorbent assay to detect HEV-IgG. Demographic data were statistically evaluated by t-test and univariate analysis, and HEV infection risk factors were statistically evaluated by a binary logistic regression model.

Results: The average age of the 952 questionnaire responders was 47.16 + 8.09 years. The demographic parameters of education level, income, experience of stillbirth, and age were associated with HEV-IgG positivity (all P less than 0.05). Age, occupation, and income were identified as independent risk factors for HEV-IgG positivity (all P less than 0.05). No statically association was found between sexual behavior and anti-HEV or anti-HPV levels, or HEV infection.

Conclusion: The female population surveyed in Xinmi, Henan Province showed a higher HEV-IgG positive rate than generally reported in the literature, and this rate shows an increasing trend with age, Risk factors for HEV infection among this group are age, income and occupation.

Background: Although existing studies have identified some genetic loci associated with chronic obstructive pulmonary disease (COPD) susceptibility, many variants remain to be discovered. The aim of this study was to further explore the potential relationship between single nucleotide polymorphisms (SNPs) and COPD risk.

Methods: Nine hundred and ninety-six subjects were recruited (498 COPD cases and 498 healthy controls).

Research progress of femoral head necrosis in HIV-infected patients.

Ann Med

December 2025

Department of Joint and Sports Medicine, Zhongnan Hospital, Wuhan University, Wuhan, China.

As life expectancy among patients infected with the human immunodeficiency virus (HIV) increases, a growing number of complications have been observed. This population displays an elevated risk of ischemic necrosis of the femoral head in comparison to the general population, which may be attributed to HIV infection, antiretroviral medication use, and hormone application. Patients infected with the human immunodeficiency virus (HIV) who also have necrosis of the femoral head tend to present at an earlier age, with a rapid disease progression and a high incidence of bilateral onset.
