Obstructive Sleep Apnea Syndrome (OSAS) is a common condition in children, and is characterized by intermittent partial or complete occlusion of the upper airway during sleep, leading to profound disturbances in homeostatic gas exchange, frequent arousals and disturbed sleep architecture. Pediatric OSAS is associated with a multitude of end-organ morbidities, most of which have been uncovered in the last decade. Of particular interest are the cardiovascular complications that may develop in children with OSAS, since they are posited to have not only an immediately significant impact on cardiovascular health during childhood, but may also affect cardiovascular outcomes later during adult life. In this review, we will present the specific cardiovascular complications that have thus far been described in children with OSAS, with reference to pertinent mechanisms, and potential implications.

Purpose: Homoarginine (hArg) is an arginine metabolite that has been known for years, but its physiological role in the body remains poorly understood. For instance, it is well known that high hArg concentrations in the blood are protective against several disease states, yet the mechanisms behind these health benefits are unclear. This review compiles what is known about hArg, namely its synthetic pathways, its role in different diseases and conditions, and its proposed mechanisms of action in humans and experimental animals.

Background: Impairment of the visceral pleura following thoracic surgery often leads to air leaks and intrathoracic adhesions. For preventing such complications, mesothelial cell proliferation at the pleural defects can be effective. To develop new materials for pleural defects restoration, we constructed a hybrid artificial pleural tissue (H-APLT) combining polyglycolic acid (PGA) nanofiber sheets with a three-dimensional culture of mesothelial cells and fibroblasts and evaluated its therapeutic efficacy in a rat pleural defect model.

Background: Extracorporeal membrane oxygenation (ECMO) is a critical treatment for severe cardiopulmonary failure. However, traditional ECMO decannulation methods, such as manual compression and surgical repair, are associated with significant complications. This study evaluates suture-mediated closure devices, specifically Perclose ProGlide, as a potentially favorable decannulation strategy.

Sedentary lifestyles and prolonged physical inactivity are often linked to poor mental and physical health as well as an increased risk of a number of chronic illnesses, including cancer, obesity, type 2 diabetes, and cardiovascular problems. Metabolic Syndrome (MetS), as the new disease, has emerged as the world's leading cause of illness. Despite having its roots in the West, this issue has now completely globalized due to the development of the Western way of life throughout the world.

Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.
