The magnificent frigatebird ( MFB) is a widely distributed seabird. It has breeding areas in the tropical Atlantic Ocean and the Pacific Ocean (extending along Central America up to Baja California) (Schreiber & Burger, 2001). The (MFB-Gal) subspecies is native to the Galápagos Islands.

- The study investigates how competing risks, like allograft failure and death with a functioning graft, affect the performance of prognostic models used for kidney transplant recipients.
- The research involves 11,046 kidney transplant recipients across 10 countries, developing models using various regression techniques to predict long-term graft failure while carefully evaluating their accuracy and reliability.
- Results indicate that both standard Cox models and competing risk models provide similar predictions for graft failure, with high concordance indices, confirming their usefulness in clinical settings.
For patients with drug-resistant epilepsy, successful localization and surgical treatment of the epileptogenic zone (EZ) can bring seizure freedom. However, surgical success rates vary widely because there are currently no clinically validated biomarkers of the EZ. Highly epileptogenic regions often display increased levels of cortical excitability, which can be probed using single-pulse electrical stimulation (SPES), where brief pulses of electrical current are delivered to brain tissue.

Objective: To test the noninferiority of hybrid CR compared with traditional CR in terms of cardiovascular events.
Design, Setting, And Participants: This pragmatic, multicenter, parallel arm, open-label randomized clinical trial (the Hybrid Cardiac Rehabilitation Trial [HYCARET]) with blinded outcome assessment was conducted at 6 referral centers in Chile.
Background: The aim of this study was to evaluate the impact of peritoneal dialysis (PD) strategy on technique and patient survival.
Methods: This was a retrospective, single-center study conducted on consecutive patients with chronic kidney disease who underwent PD between January 2009 and December 2019. The study sample was stratified into four different groups according to PD technique [automated (APD) or manual (CAPD)] and icodextrin use (yes versus no).
