Association of different inflammatory indices with risk of early natural menopause: a cross-sectional analysis of the NHANES 2013-2018.

Background: Early natural menopause, characterized by the cessation of ovarian function before the age of 45, has been a subject of prior research indicating that inflammation may predict the onset of menopause. However, the specific relationship between peripheral blood inflammatory parameters and early natural menopause remains ambiguous.

Methods: This observational study utilized data from the National Health and Nutrition Examination Survey (NHANES) spanning the years 2013-2018.

The relationship between corporate entrepreneurship and its competitiveness in China: The moderating effect of employee stock ownership plan.

Using data from Chinese publicly listed companies spanning from 2010 to 2022, this study examines the relationship between corporate entrepreneurship, employee stock ownership plans (ESOPs), and corporate competitiveness. The findings show that the influence of corporate entrepreneurship on enterprise competitiveness is significantly "U-shaped". As the degree of corporate entrepreneurship increases, it initially demonstrates a significant negative impact on enterprise competitiveness, followed by a significant positive impact.

Characteristics and utility of high-resolution optical coherence microscopy images of endocervical canal lesions.

Objectives: To investigate optical coherence microscopy (OCM) imaging features and the application value of these high-resolution images for identifying endocervical canal lesions (ECLs), which is a clinical dilemma in cervical cancer screening programs.

Methods: In total, 520 OCM images were obtained by scanning the cervical canal lesions with an ultra-high-resolution OCM system (204 specimens from 73 patients). The OCM morphologic characteristics of ECLs were observed and summarized, and then 3 researchers performed a diagnostic test of OCM images of cervical canal lesions.
