Introduction: Detrusor contractions can be classified as either volitional or involuntary. The latter are a hallmark of urge urinary incontinence. Understanding differences in neuroactivation associated with both types of contractions can help elucidate pathophysiology and therapeutic targets.

: The purpose of this research was to create a peak detection algorithm and machine learning model for use in triathlon. The algorithm and model aimed to automatically measure movement cadence in all three disciplines of a triathlon using data from a single inertial measurement unit and to recognise the occurrence and duration of cycling task changes. : Six triathletes were recruited to participate in a triathlon while wearing a single trunk-mounted measurement unit and were filmed throughout.

Purpose: Patients with refractory neurogenic bladder dysfunction may require urinary reconstruction due to severe incontinence, difficulty with catheterization, and to prevent upper urinary tract compromise. We evaluated long-term decisional regret and associated factors following urinary reconstruction in spinal cord injury patients.

Materials And Methods: We interviewed patients with spinal cord injuries who underwent bladder reconstruction surgery at least ten years ago, administering validated surveys on bowel quality of life and dysfunction, urinary tract infections, and decisional regret.

Article Synopsis
  • Hammerhead sharks belong to the Sphyrnidae family, which is noted for their unique head shape and consists of a diverse Miocene radiation of sharks.
  • The bonnethead shark (Sphyrna tiburo) is divided into two recognized subspecies based on geographic distribution, with genetic evidence suggesting a more complex species structure.
  • Research comparing vertebral counts and morphological characteristics has confirmed the presence of two distinct species in the Western Atlantic: S. tiburo and a newly identified species, S. alleni, distinguished by specific vertebral counts and a unique shovel-shaped head.

Introduction: COPD is characterised by airflow obstruction, expiratory airway collapse and closure causing expiratory flow limitation (EFL) and hyperinflation. Supine posture may worsen ventilatory function in COPD, which may cause hyperinflation to persist and contribute to symptoms of orthopnoea and sleep disturbance. Our aim was to determine the impact of supine posture on hyperinflation, dynamic elastance and EFL in COPD and healthy subjects.
