AI Article Synopsis

  • Male NZB/NZW F1 hybrid mice typically die of lupus nephritis or lymphoid malignancy in their second year of life, but androgen therapy significantly improves their survival rates.
  • Delaying androgen treatment until 9 months still enhances lifespan, showing the therapy's effectiveness later in life.
  • The therapy also boosts immune function, evidenced by stronger spleen cell responses and reduced abnormal suppressor activity, indicating a potential mechanism for improved survival through enhanced T lymphocyte function.

Article Abstract

Male NZB/NZW F1 hybrid (B/W) mice survive their first year of life and die of lupus nephritis or lymphoid malignancy during the second year. Androgen therapy, even if delayed until 9 months of age, improves survival considerably. We report here that androgen therapy in aged B/W mice is associated with improved cell-mediated immune function as well as increased survival. Androgen treated mice have significantly augmented spleen cell responses to phytohaemagglutinin (PHA) and a decreased incidence of abnormal splenic suppressor activity. These results suggest that androgen may prolong survival in B/W mice in part through an effect on abnormally suppressive regulatory cells that impair T lymphocyte function.

Purpose: Several studies suggest a linkage between PCOS and autoimmunity with a high frequency of chronic autoimmune thyroiditis (AIT) reported in PCOS patients, however, this subject remains controversial. The aim of this study was to investigate the prevalence of AIT in PCOS women and identify parameters that would serve as independent predictors of AIT.

Methods: Two hundred fifty seven (257) PCOS patients according to the NIH criteria and one hundred forty three (143) controls, women with normal menstrual cycles and without clinical or biochemical hyperandrogenism, were recruited for the study.

Background: Metastatic castration-resistant prostate cancer (mCRPC) treatment is advancing yet Nordic, real-world evidence for its use is scarce. In this population-based cohort study, we describe characteristics of patients with mCRPC, and their treatment patterns and survival outcomes in Finland.

Methods: Incident patients with mCRPC diagnosed during 2013-2021 were identified from data lakes in two large and representative, Finnish hospital districts, and linked to data on drug purchases and causes of death from national registries.

Department and Institute of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, No.1095 Jiefang Avenue, Wuhan, Wuhan, 430030, P.R. China.

Introduction: Prostate cancer is one of the most common cancers in the United States with a high mortality rate. In recent years, the traditional opinion about prostate microbiome was challenged. Although there still are some arguments, an escalating number of researchers are shifting their focus toward the microbiome within the prostate tumor environment.

This study compared the efficacy and safety of glucogan-like peptide-1 receptor agonists (GLP1RAs) combined with metformin versus metformin alone in women with polycystic ovary syndrome (PCOS). A systematic search of "PubMed", "EMBASE", "Cochrane Library", and "Web of Science", "Google Scholar" was conducted up to September 2024. Studies were included if they were RCTs investigating the combination of GLP1RAs and metformin in women diagnosed with PCOS.
