This study aimed to analyse the association between sex hormones and bone age (BA) in boys aged 9-18 years, both individually and interactively, and further to explore whether nutritional status may influence this association. A retrospective analysis was performed among 1382 Chinese boys with physical measurements, sexual characteristics, BA radiographs and sex hormone indicators from February 2015 to February 2022. A total of 470 (34.0%) boys had advanced BA. BA was positively associated with estradiol, luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone in both advanced and normal BA groups after adjusting for age, genetic height and body mass index. Multiple logistic regression showed that after adjusting for covariates, estradiol (odds ratio [OR] = 1.66, 95% confidence interval [CI]: 1.14-2.12), LH (OR = 1.43, 95% CI: 1.04-1.96), and testosterone (OR = 1.58, 95% CI: 1.17-2.13) were significantly associated with the increased risk of advanced BA in boys, and the association was reinforced when these hormones were interactively explored. Stratified by nutritional status, the interaction between estradiol, LH, and testosterone showed a strong association with advanced BA in boys with normal weight.

In species with genetic sex determination (GSD), the sex identity of the soma determines germ cell fate. For example, in mice, XY germ cells that enter an ovary differentiate as oogonia, whereas XX germ cells that enter a testis initiate differentiation as spermatogonia. However, numerous species lack a GSD system and instead display temperature-dependent sex determination (TSD).

Objective: The natural history of cephaloceles is not well understood. The goal of this study was to better understand the natural history of fetal cephaloceles from prenatal diagnosis to the postnatal period.
Methods: Between January 2013 and April 2023, all patients evaluated with a cephalocele at the Center for Fetal Diagnosis and Treatment were identified.

Objective: Although increasing evidence suggests that depression/distress involves inflammatory processes, its potential sex differences and the temporal directions for this association remain elusive.
Methods: We examined the temporal association between serum inflammatory mediators and depression/distress as measured by the Center for Epidemiologic Studies Depression Scale (CES-D) and the Kessler Psychological Distress Scale (K6), in non-depressed working men and women (n = 61 and 43, respectively) by a 16-month prospective design.
Results: Fully-adjusted partial correlation analyses revealed that in men, a lower IFN-γ predicted subsequent increases in CES-D and K6 scores, while a higher TNF-α predicted increased K6 scores.
Background: Adherence to self-care behaviors can prevent or delay adverse outcomes associated with cardiovascular disease (CVD). Sex and socioculturally constructed gender might impact individuals' ability to adhere to healthy lifestyles.
Objective: The aim of this study was to systematically identify, evaluate, and synthesize the literature on the influence of sex and gender on adherence to self-care behaviors for CVD risk management in the global context.
