Past studies documented the presence of epididymal/testicular fusion anomalies and persistence of a patent processus vaginalis in a small case-series of cryptorchid and/or hydrocele patients. The primary aim of this study was to determine the prevalence of the epididymal/testicular anomalies in a series of more than 1000 cryptorchid patients compared with controls. Secondary aims were: (i) to investigate the association between the cryptorchidism and the patency of p. vaginalis; and (ii) to correlate the epididymal/testicular fusion anomalies with the position of the testis and with the patency of the p. vaginalis. The clinical and surgical data of 1002 cryptorchid patients and 230 controls were retrospectively retrieved and analysed. Epididymal/testicular fusion anomalies were classified as: (i) normal anatomy; (ii) minor anomalies; and (iii) major anomalies. Statistical analysis was performed using the Student's t-test and Chi-square tests. The prevalence of the epididymal/testicular fusion anomalies was higher in the cryptorchid group compared with that of the control group (minor and major anomalies in cryptorchids vs. controls, respectively: 42.2 vs. 5.6% and 9.3 vs. 1.6%, P < 0.0001). Moreover, we documented a correlation of these anomalies with a more proximal localization of the testis (minor and major anomalies in proximal vs. distal location of the testis, respectively: 62.5 vs. 34.8% and 19.1 vs. 6.3%, P < 0.0001) and with the persistence of a widely patent p. vaginalis (minor and major anomalies in widely patent p. vaginalis vs. narrow duct, respectively: 51.7 vs. 42.2 and 11.9% vs. 7.8%, P < 0.001). In conclusion, the epididymal/testicular fusion anomalies were strongly associated with cryptorchidism and the persistence of a widely patent peritoneal vaginal duct. Although it remains unclear whether these anomalies cause non-descent of the testis or, conversely, result from the cryptorchidism or from the persistence of a widely patent duct, our data re-enforce this association.

Background: While prolonged operative time and increased levels fused have been shown to increase the risk of prolonged intensive care unit (ICU) length-of-stay (LOS), studies are limited in guiding decision-making regarding the need for intensive care postoperatively. This is especially the case among the cohort of adolescent idiopathic scoliosis (AIS) patients undergoing posterior spinal fusion (PSF); associations between comorbidities and ICU LOS are not well-delineated.
Methods: AIS patients who underwent PSF from January 1st, 2016 to December 1st, 2016 at 101 participating centers were identified using the American College of Surgeons (ACS) National Surgical Quality Im-provement Project (NSQIP) Pediatric database.

Background: Diabetic myocardial disorder (DbMD, evidenced by abnormal echocardiography or cardiac biomarkers) is a form of stage B heart failure (SBHF) at high risk for progression to overt HF. SBHF is defined by abnormal LV morphology and function and/or abnormal cardiac biomarker concentrations.
Objective: To compare the evolution of four DbMD groups based on biomarkers alone, systolic and diastolic dysfunction alone, or their combination.

Bisphenol A (BPA) is a common endocrine disruptor chemical that is widely used in the production of food plastic packaging, and it has been shown to potentially harm the reproductive system. However, the specific mechanism by which BPA induces apoptosis of Leydig cells (LCs) and inhibits testosterone synthesis in these cells is unclear. In the present study, TM3 cells were used as an experimental model in combination with a reactive oxygen species (ROS) scavenger (N-acetylcysteine), Caspase-3 inhibitor (Ac-DEVD-CHO), autophagy activator (Torin2), and autophagy inhibitor (Chloroquine) to investigate the potential mechanisms by which BPA causes TM3 cell damage in vitro.

Neurodegenerative diseases are a group of diseases that pose a serious threat to human health, such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD) and Amyotrophic Lateral Sclerosis (ALS). In recent years, it has been found that mitochondrial remodeling plays an important role in the onset and progression of neurodegenerative diseases. Mitochondrial remodeling refers to the dynamic regulatory process of mitochondrial morphology, number and function, which can affect neuronal cell function and survival by regulating mechanisms such as mitochondrial fusion, division, clearance and biosynthesis.

Background: Horseshoe kidney is the most common renal fusion anomaly, occurring in approximately 1 in 500 individuals worldwide. It is characterized by abnormalities in kidney position, rotation, and vascular supply. While often asymptomatic, horseshoe kidneys can lead to urological complications, primarily due to ureteric obstruction and impaired urinary drainage.
