Lower Extremity Stretch-Shortening Cycle Performance in the Vertical and Horizontal Direction as Key Determinants of Success in Collegiate Male Taekwondo.

Background/objectives: The underlying mechanisms of taekwondo-specific jumping ability among different competition levels are still unknown. This study aimed to compare vertical and horizontal stretch-shortening cycle (SSC) performance between athletes of different competitive levels and examine the relationships of force and power production abilities between those two directions in Taiwanese collegiate-level male taekwondo athletes.

Methods: Seventeen male collegiate taekwondo athletes were divided into two groups: medalists (MG, n = 8) and non-medalists (NMG, n = 9); both groups performed countermovement jumps (CMJ) on a force platform and single-leg lateral hops (SLLHs) via an optoelectronic measurement system.

Cardiovascular and thromboembolic outcomes with immune checkpoint inhibitors in gastroesophageal cancer: a propensity score-matched cohort study.

Background: Immune checkpoint inhibitors (ICIs) have been associated with an increased risk of cardiovascular and thromboembolic events. However, the incidence of cardiovascular and thromboembolic events associated with ICIs in gastroesophageal cancers is unknown.

Methods: We performed a propensity score-matched cohort study using the TriNetX Analytics Network database, which comprises de-identified data from over 130 participating healthcare institutions.

Clinical Trial: Precise Administration of Sucralfate Powder in Prevention of Delayed Postpolypectomy Bleeding. A Randomized Controlled Trial.

Background/aims: Delayed postpolypectomy bleeding occurs in approximately 1% to 2% of all patients undergoing colonoscopic polypectomy, and this rate increases to 6% in patients with large (>2 cm) colon polyps. Sucralfate can protect the mucosa and promote its healing. This study was conducted to investigate whether colonoscopic spraying of sucralfate powder on polypectomy wounds can prevent delayed postoperative bleeding.

Effects of Exergame Training on Executive Function and Heart Rate Variability in Middle-Aged and Older Adults: A Randomized Controlled Study.

Exergame has become widely popular and offers great levels of cognitive demands, thus may facilitate cognitive benefits. In addition, researchers have proposed that cardiac autonomic function, assessed via heart rate variability (HRV), is associated with cognitive executive function. However, few exergame training studies have investigated this relationship.
