Article Abstract
Purpose: Estrogen receptor (ER) genes play key roles in male and female reproduction. Non-obstructive azoospermia (NOA) and severe secretory oligozoospermia (SOL) are the most severe and complex conditions impacting male fertility. This meta-analysis aimed to study the association between PvuII ( rs2234693, 397T>C ), XbaI ( rs9340799, 351G>A ), AluI (1730G>A, rs4986938), and RsaI (1082G>A, rs1256049) polymorphisms and spermatogenic failure.
Materials And Methods: The literature in PubMed, Medline, Embase, Web of Science, Cochrane Library, China Science and Technology Journal Database, WanFang data, and China National Knowledge Infrastructure databases were systematically searched, and a meta-analysis was conducted to investigate the association between polymorphism in estrogen receptors and spermatogenic failure. According to a set criterion, 10 studies were included for analyses.
Results: ER α XbaI polymorphism was a decreased risk of NOA. The ER α PvuII polymorphisms does not associate with NOA and SOL. ER β AluI polymorphism increased the risk of NOA in Caucasian population. ER β RsaI polymorphism was a decreased risk of NOA and SOL in Caucasian males.
Conclusion: The ER α XbaI and ER β RsaI polymorphisms are associated with the risk of NOA and SOL.

Study Question: What is the diagnostic yield and the pre-testicular sperm extraction (TESE) prognostic value of a non-obstructive azoospermia (NOA)-specific virtual gene panel?
Summary Answer: The diagnostic yield in our cohort was 6.1%, and by combining our data with published literature, we identified 11 genes compatible with testicular sperm production and 19 genes associated with no sperm retrieval in carriers of pathogenic (P) or likely pathogenic (LP) mutations.
What Is Known Already: Azoospermia, the most severe form of male infertility, affects ∼1% of the male population, with TESE being the primary treatment option.

Although dietary factors are increasingly implicated as crucial determinants of male fertility, specific dietary risk factors and their metabolic mechanisms remain poorly understood. In this study, patients with non-obstructive azoospermia (NOA) or severe oligospermia (EO) demonstrated significantly elevated erucic acid (EA) levels, with a nearly 3-fold increase in serum (P < 0.0001) and a 27 % increase in semen (P = 0.

Objectives: Accurate diagnosis of sepsis is needed to initiate life-saving treatment decisions. Biomarkers capable of identifying both acute infection and sepsis are required to assist clinicians.
Methods: A real-life heterogeneous cohort of 388 patients with suspected acute infections was recruited at presentation to the ED.

Background: Differentiating tumor progression from posttreatment changes, such as pseudoprogression and radiation necrosis, remains a significant challenge in neuro-oncology. Contrast Clearance Analysis (CCA), or Treatment Response Assessment Maps, has developed as a promising tool for this purpose. This systematic review and meta-analysis evaluate the diagnostic accuracy of CCA in distinguishing tumor progression from treatment-induced changes and compare its performance with other advanced imaging modalities.

Background: Stereotactic radiotherapy (SRT) is the main treatment for patients with 1 to 3-5 brain metastases (BMs) but with the compromise of a higher risk of distant brain failure (DBF) in comparison with whole brain radiotherapy. Early DBF has a significant negative impact on overall survival (OS). We propose to build and validate a prediction model of early DBF.
