Published: September 2020

Monocusp valves are thought to reduce early operative mortality and morbidity associated with pediatric tetralogy of Fallot repair. As there are no published randomized clinical trials comparing outcomes with and without a monocusp valve, we performed a meta-analysis of observational studies in accordance with established protocols. After systematically searching PubMed, the Cochrane Library, and Google Scholar, 12 studies were included. The operative mortality was compared in 695 patients, and we found no difference between patients with and patients without a monocusp valve. Monocusp valves may not improve operative mortality of tetralogy of Fallot repair in pediatric patients.

If a shortened lifespan is evolutionarily advantageous, it becomes more likely that nature will strive to change it accordingly, affecting how we understand aging. Premature mortality because of aging would seem detrimental to the individual, but under what circumstances can it be of value? Based on a relative incremental increase in fitness, simulations were performed to reveal the benefit of death. This modification allows for continuous evolution in the model and establishes an optimal lifespan even under challenging conditions.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.

Introduction: Blunt traumatic aortic injury (TAI) is a critical condition and a leading cause of mortality in trauma patients, often resulting from high-speed accidents. Thoracic endovascular aortic repair (TEVAR) has developed into the preferred therapeutic approach due to its minimally invasive nature and promising outcomes. This study evaluates the safety and efficacy of TEVAR for managing TAI over a 10-year period at a Level-1 trauma center.
