Validation of ACR TI-RADS performance in transition age: results from a multicenter retrospective study by the TALENT study group.

Purpose: Although thyroid nodules are less common in the pediatric population, the risk of malignancy is higher than in adult patients. The aim of this study was to evaluate the ultrasonographic predictive factors of malignancy in thyroid nodules and to validate American College of Radiologists (ACR) TI-RADS performance in transition age patients.

Methods: One hundred forty-two patients aged between 14 and 21 years referred to the participating centers for FNA biopsy of a thyroid nodule between 2007 and 2022 were included and ultrasound reports and sonographic images were retrospectively analyzed.

Testicular ultrasonographic features predict future risk for bilateral testicular germ cell tumour: A long-term single centre follow-up study.

Background: Bilateral testicular germ cell tumours (B-GCT) are rare, with an incidence of 2-5%, and can be classified as synchronous (sB-GCT) or metachronous (mB-GCT). Our study aimed to identify clinical, biochemical, and radiological risk factors for mB-GCT in a cohort of patients with GCT at a single tertiary referral centre.

Methods: This retrospective case-control study included patients with GCT referred to Policlinico Umberto I-Sapienza University of Rome, from 2005 to 2023.

Total osteocalcin levels are independently associated with worse testicular function and a higher degree of hypothalamic-pituitary-gonadal axis activation in Klinefelter syndrome.

Purpose: The role of osteocalcin (OCN) in pubertal development, male hypogonadism, and the effect of testosterone (Te) replacement therapy (TRT) remains unclear. We aimed to investigate the total OCN (tOCN) concentrations in male patients with Klinefelter syndrome (KS), a model of adult hypergonadotropic hypogonadism.

Methods: This retrospective longitudinal study investigated 254 male patients with KS (47,XXY) between 2007 and 2021 at an academic referral center, categorized as (1) prepubertal, (2) pubertal, and (3) adults.

Length of stay in the clinical wards in a hospital after introducing a multiprofessional discharge team: An effectiveness improvement report.

Introduction: Emergency overcrowding is a problem in hospitals worldwide. The expansion of wards has limitations. Hospital administrative leaders are constantly looking for opportunities to improve the efficiency of resource use.

From Klinefelter Syndrome to High Grade Aneuploidies: Expanding the Gene-dosage Effect of Supernumerary X Chromosomes.

Objective: High-grade aneuploidies of X and Y sex chromosomes (HGAs) are exceedingly rare and complex conditions. We aimed to investigate the effect of supernumerary X chromosomes (extra-Xs) on the clinical, hormonal, metabolic, and echocardiographic features of patients with HGAs.

Design And Methods: In a cross-sectional study, we compared 23 subjects with HGAs and 46 age-matched subjects with 47,XXY Klinefelter syndrome (KS), according to the number of extra-Xs: two (47,XXY and 48,XXYY), three (48,XXXY and 49,XXXYY), or four supernumerary Xs (49,XXXXY).
