Summary: Steroid hormones are crucial natural hormones that regulate physiological processes in vertebrates; both natural and synthetic steroid hormones have been identified as widespread aquatic contaminants; experiments have shown that even at extremely low concentrations, steroid hormones can adversely affect reproduction in aquatic vertebrates.

Summary: Metabolomics is a promising analytical method for the diagnosis and prognosis of breast cancer, offering a comprehensive non-invasive approach. Targeted metabolomics of steroid hormones play a crucial role in the classification and development of breast cancer, with high potential for effective diagnosis and monitoring of disease progression.

Summary: Sex hormones play a crucial role in bone growth and health through gene regulation, mediated by nuclear receptors. The dysfunction of these receptors in specific bone cells or at specific differentiation stages can lead to phenotypic abnormalities in the skeleton. This review focuses on recent findings in chromatin-level gene regulation and the role of enhancer RNAs and liquid-liquid phase separation in transcription initiation through chromatin reconfiguration.

Summary: This study reviews the various effects of melatonin on biological functions, discusses the interactions between melatonin and sex hormones, and highlights the impact of melatonin on female gonadal steroidogenesis and hormonal control. It suggests that there is ambiguity in the influence of sex differences on the circadian rhythms of melatonin, and the debate surrounding the reciprocal relationship between melatonin and reproductive hormones remains inconclusive.

Summary: The study assessed the effect of endogenous steroid hormone metabolites on Lp(a) levels and found that the impact of endogenous hormone levels on Lp(a) variability was small at best, suggesting a negligible influence on the wide range of Lp(a) variability.

Summary: This study summarizes the correlation between sex hormone levels and COVID-19. The findings suggest that COVID-19 patients have lower levels of T/LH, FSH/LH, and SHBG, and higher levels of LH and E-2/T. These findings may be helpful in evaluating the severity of COVID-19.

Summary: The study found that maternal serum levels of poly- and perfluoroalkyl substances (PFAS) are associated with sex steroid hormone levels during pregnancy. Specifically, PFHxS is associated with increased testosterone levels in male fetuses, while PFNA and PFDA are associated with increased free testosterone levels in male fetuses. For female fetuses, PFHxS is associated with increased levels of estradiol and estriol. No associations were found for PFOS and PFOA.

Summary: The application of hormones in fish production in swamps can enhance productivity, but chemical contamination in water poses a critical issue that affects aquatic organisms, particularly the sexual characteristics of fish. Residual steroid hormones have adverse effects on the environment, biological activities, and human health, especially leading to feminized properties in male fish.

Summary: Steroids play important roles in maintaining cellular homeostasis as membrane components and signaling metabolites. Both uptake and synthesis of steroids are crucial for mammalian cells. Dysregulation of steroid levels has profound effects on cellular function and overall health. Mitochondria, primarily located in the endoplasmic reticulum, are essential for cholesterol production and processing of steroid products. Understanding the regulatory roles of mitochondria in steroid synthesis can lead to targeted approaches for controlling steroid levels.

Summary: The study aimed to determine if continuous exposure to isoflavones alters the endocrine axis effect on testicular function in adult male rats. The results showed that low and high doses of isoflavones caused a hormonal imbalance, leading to decreased androgen levels and increased estrogen levels. This imbalance was associated with reduced sperm quality parameters and testicular weight. Overall, continuous exposure to isoflavones disrupted the endocrine axis and caused defects in testicular function.

Summary: The adrenal cortex produces specific steroid hormones including steroid sulfates, which may play a role in the pathophysiology of adrenal tumors and serve as potential biomarkers. Recent analytical developments may target sulfated steroids specifically.

Summary: This study found that cadmium exposure during pregnancy may lead to lower testosterone levels in pregnant women, while estrogen levels remain unchanged. This effect may be stronger in pregnancies carrying female fetuses. Further research is needed to understand how alterations in gestational testosterone activity may impact pregnancy and child health.

Summary: The study found that neighborhood walkability is associated with lower levels of androgens and estrone, and increased SHBG in postmenopausal women, as well as lower levels of DHEAS in premenopausal women. It is important to note that the associations were more pronounced in postmenopausal women.

Summary: The study aimed to evaluate the safety and impact of Dexmedetomidine Hydrochloride (DH) administration during pediatric invasive intracranial electroencephalography (IEEG). The results showed that DH administration was not associated with adverse events and did not significantly affect the frequency of seizures captured on the IEEG and the duration of hospitalization.

Summary: This study used design thinking to develop a community pharmacist-led intervention for people living with epilepsy. Four features - pharmacist-patient consultations, care plan development, regular check-ins, and care coordination with other health care providers - were identified as desirable, feasible, and viable for the intervention. The study highlights the importance of involving pharmacists in epilepsy care and provides evidence-based features for such interventions.

Summary: The purpose of this study was to identify factors associated with insomnia in patients with epilepsy. The results showed that nocturnal seizures and anxiety were independently associated with insomnia in these patients. Patients with epilepsy and insomnia were more likely to experience depression and excessive daytime sleepiness.
