Description of the Dunning-Kruger effect in general surgery residents during laparoscopic cholecystectomy: a blinded prospective study.

Purpose: The purpose of this study is to assess whether the Dunning-Kruger effect occurs in surgical residents when performing laparoscopic cholecystectomy in a porcine model.

Methods: Prospective blinded study, which counted with forty PGY-1 general surgery residents who agreed to participate in the study were blindly recruited to perform a laparoscopic cholecystectomy in a porcine model. At the end of the procedure, the participants assigned a score of 0-10 for their own performance and the video of the operation was independently assessed by 2 experienced laparoscopic surgeons using a validated tool.

The Beginning of Senior Career in Team Sport Is Affected by Relative Age Effect.

Many previous studies in national team sports did not report evidence about relative age effect (RAE) in senior categories. This study aimed for the first time to determine if the RAE may specifically affect the early, but not the late, phase of senior career in elite team sports. A total of 3,319 birthdates (basketball: = 642; rugby: = 572; soccer: = 1318; volleyball: = 337; water polo: = 450) of elite senior players were analyzed.

The relative age effect is larger in Italian soccer top-level youth categories and smaller in Serie A.

The relative age effect (RAE; i.e., an asymmetry in the birth distribution) is a bias observed in sport competitions that may favour relatively older athletes in talent identification.

Impact of body mass index, age and varicocele on reproductive hormone profile from elderly men.

Objectives: To study the impact of obesity, age and varicocele on sexual hormones of adult and elderly men.

Materials And Methods: 875 men who were screened for prostate cancer were enrolled in this study. Data recorded comprised age, body mass index (BMI), serum levels of total testosterone (TT), free testosterone (FT), sex hormone-binding globulin (SHBG), luteinizing hormone (LH) and follicular stimulating hormone (FSH).
