Objective: We previously reported the possible pathogenic role, among infants born ≤29 weeks, of transfusions in bronchopulmonary dysplasia. The present study examined this association in infants born >31 weeks.

Study Design: Analysis of red blood cell (RBC) and platelet transfusions in five NICUs to infants born >31 weeks, and chronic neonatal lung disease (CNLD) at six-weeks of age.

Article Synopsis
  • - The study investigates how inspiratory threshold loading (ITL) affects cognition and prefrontal cortex (PFC) activity compared to lower limb pedalling during dual tasks, finding that ITL leads to more cognitive impairment and increased PFC activity.
  • - Thirty healthy participants performed various tasks, including ITL and pedalling, while their cognitive performance and PFC activity were measured using functional near-infrared spectroscopy.
  • - Results showed that ITL-Stroop significantly impaired reaction time and accuracy more than pedalling-Stroop, and ITL caused higher feelings of dyspnoea and exertion, indicating ITL creates more cognitive interference than rhythmic pedalling.

Background: Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disease associated with respiratory muscle weakness and activity-limiting symptoms such as dyspnea. Respiratory muscle strength training (RMST) is an empirically validated therapy to increase respiratory muscle strength. The theoretically-informed, technology-enhanced RESPiratory FITness (RESP-FIT) intervention for COPD is a 6-week combined inspiratory and expiratory muscle strength training program with symptom measurement in real time via ecological momentary assessment (EMA).

Background: Head and neck cancer (HNC) patients often have dysphagia following surgical and/or chemoradiation treatment, which can lead to reduced quality of life. Some patients suffer from decreased tongue strength and mobility that may cause discomfort and difficulty with swallowing. Our group has developed a patented genioglossus muscle strength trainer (GMST) to increase tongue protrusive force that has been used in patients with sleep apnea.

Platelet transfusions are life-saving treatments for specific populations of neonates. However, recent evidence indicates that liberal prophylactic platelet transfusion practices cause harm to premature neonates. New efforts to better balance benefits and risks are leading to the adoption of more restrictive platelet transfusion guidelines in neonatal intensive care units (NICU).
