Effects of low-volume court-based sprint interval training on aerobic capacity and sport-specific endurance performance in competitive tennis players.

Sprint interval training (SIT) is a potent exercise strategy to enhance athletes' aerobic capacity in a time-efficient manner. The purpose of this study was to examine the effect of a low-volume court-based SIT program on aerobic capacity and sport-specific endurance performance for competitive tennis players. Sixteen competitive collegiate tennis players were randomly assigned to the SIT (court-based repeated-sprint training) and traditional endurance training (ET; 45-min continuous treadmill running) groups for a 6-week intervention (3 sessions/week).

Outcome of extra-nodal follicular lymphoma affected by choice of induction chemoimmunotherapy and maintenance rituximab - real-world retrospective study.

The importance of extra-nodal disease has been well recognized in follicular lymphoma, and is incorporated into various prognostic tools. However, the optimal treatment strategy for this subgroup remains unclear. In this multicenter retrospective study, we analyzed 143 patients who received either R-CHOP or Bendamustine-Rituximab (BR), with a median follow-up of 69.

Performance of respiratory gated 4D flow MRI with adaptive k-space reordering in healthy controls and aortic dissection: reproducibility and agreement with 2D phase contrast MRI.

A four-dimensional phase-contrast magnetic resonance imaging sequence with respiratory-controlled adaptive k-space reordering (ReCAR-4DPC) offers potential benefits of improved scan efficiency and motion robustness. The purpose of this study was to evaluate the reproducibility of flow measurement using this technique and to compare hemodynamic metrics obtained to two-dimensional phase contrast MRI (2DPC)-derived metrics of the thoracic aorta. ReCAR-4DPC was performed with identical scan parameters in 15 healthy volunteers (6M,9F, mean [range] 37 [23-47] years) and 11 patients with thoracic aortic dissection (6M,5F, 56 [31-81] years) and acquisition time was recorded.

Parent coaching to target language outcomes for Chinese-learning autistic preschoolers: A preliminary study.

Purpose: The present study evaluates the preliminary effectiveness of a parent-implemented support program to enhance language outcomes in Chinese-learning preschoolers with a confirmed diagnosis or at elevated likelihood of autism, a lifelong neurodevelopmental condition. The program is delivered entirely online with the option of a group format. Because of cross-cultural differences in adult learning and parent-child interaction and because parent coaching programs for autism that are delivered online are only emerging, a specific study to evaluate the effectiveness of online support for Chinese families is warranted.
