Leg fidgeting alleviates reduced oxygen extraction in the gastrocnemius muscle caused by prolonged sitting: a randomized crossover trial.

Purpose: Oxygen extraction in skeletal muscle is an important determinant of exercise tolerance. Prolonged sitting decreases oxygen extraction in the gastrocnemius muscle. However, the underlying mechanism remains unknown, and preventive measures are yet to be established.

Prolonged Sitting Induces Elevated Blood Pressure in Healthy Young Men: A Randomized Crossover Trial.

Introduction Prolonged sitting-induced blood pooling in the lower legs can increase blood pressure through increased sympathetic nerve activity and peripheral vascular resistance, an aspect that has been understudied as a primary outcome. This study compared the effects of prolonged sitting with those of prolonged supination on blood pressure in healthy young men. Methods This randomized crossover study included 16 healthy young men (mean age: 21.

Correlation between the Closure Time of Patent Ductus Arteriosus in Preterm Infants and Long-Term Neurodevelopmental Outcome.

In patent ductus arteriosus (PDA) in preterm infants, the relationship between treatment timing and long-term developmental prognosis remains unclear. The purpose of this study was to clarify the relationship between the age in days when ductus arteriosus closure occurred and long-term development. Preterm infants with a birth weight of less than 1500 g who were admitted to our NICU over a period of 9 years (2011-2019) and were diagnosed with PDA were included.

Transoral traumatic perforation of the pyriform sinus by a marker pen: report of an infant case.

Background: Perforation of the pyriform sinus, included in hypopharyngeal injury, is a rare condition typically caused by iatrogenic factors. We present a case of an infant who developed deep cervical and mediastinal abscesses due to a traumatic pyriform sinus perforation caused by accidentally falling with a marker pen in the mouth.

Case Presentation: An 11-month-old healthy male infant fell on a trampoline with a marker pen in his mouth.
