Radiotherapy-associated Sensorineural Hearing Loss in Pediatric Oncology Patients.

During the radiotherapeutic treatment of pediatric oncology patients, they would be at a latent risk of developing ionizing radiation-induced ototoxicity when the cochlea or auditory nerve is located within the radiation field. Sensorineural hearing loss (SNHL) is an irreversible late complication of radiotherapy, and its incidence depends on various factors such as the patient's hearing sensitivity, total radiation dose to the cochlea, radiotherapy fractionation regimen, age and chemoradiation. Importantly, this complication exhibits serious challenges to adult survivors of childhood cancer, as it has been linked to impairments in academic achievement, psychosocial development, independent living skills, and employment in the survivor population.

Type 2 alveolar epithelial cell-derived circulating extracellular vesicle-encapsulated surfactant protein C as a mediator of cardiac inflammation in COVID-19.

Among the countless endeavours made at elucidating the pathogenesis of COVID-19, those aimed at the histopathological alterations of type 2 alveolar epithelial cells (AT2) are of outstanding relevance to the field of lung physiology, as they are the building blocks of the pulmonary alveoli. A merit of high regenerative and proliferative capacity, exocytotic activity resulting in the release of extracellular vesicles (EVs) is particularly high in AT2 cells, especially in those infected with SARS-CoV-2. These AT2 cell-derived EVs, containing the genetic material of the virus, might enter the bloodstream and make their way into the cardiovascular system, where they may infect cardiomyocytes and bring about a series of events leading to heart failure.
