Article Synopsis
- Accurate diagnosis of sarcopenia involves assessing muscle quality, specifically how much fat is infiltrated in muscle tissue, which is crucial for predicting mortality in TAVI patients.
- The study analyzed CT scans from 1199 patients who underwent TAVI between 2010 and 2020, employing deep learning algorithms to measure skeletal muscle density (SMD) and intermuscular adipose tissue (IMAT).
- Results indicated that low muscle quality, identified through both low SMD and high IMAT, significantly correlates with increased mortality risk, suggesting that muscle quality metrics are valuable predictors of health outcomes post-TAVI.
Referral to home-based cardiac rehabilitation (HBCR) is low among older and frailer patients due to low expectations regarding adherence by healthcare professionals. The aim of this study was to determine adherence to HBCR when old and frail patients are referred, and to explore any differences in baseline characteristics between adherent and nonadherent patients. Data of the Cardiac Care Bridge were used (Dutch trial register NTR6316).

- Older patients scheduled for heart procedures often don't follow dietary and activity guidelines, so this study looked into what helps or hinders them in making healthy changes pre-TAVI (transcatheter aortic valve implantation).
- The research involved 13 patients aged around 82, who were interviewed and analyzed by two researchers, leading to the identification of barriers like low physical capability, lack of prioritization, and ingrained habits, as well as facilitators like knowledge about health benefits, social norms, and support from others.
- The findings suggest that while many older patients see dietary and physical activity as low priorities, they may be willing to change if they understand the health benefits, indicating a need for healthcare professionals to use motivational interviewing techniques to help
It is suggested that older patients waiting for an elective surgical procedure have a poor nutritional status and low physical activity level. It is unknown if this hypothesis is true and if these conditions improve after a medical procedure. We aimed to determine the trajectory of both conditions before and after transcatheter aortic valve implantation (TAVI).

- - Older patients undergoing transcatheter aortic valve implantation (TAVI) may still face issues like physical decline and increased mortality, even if the surgery is successful.
- - A systematic review found that low muscle strength and poor physical performance (like slow walking speed or difficulty in mobility tests) were linked to higher long-term death rates after TAVI.
- - The review highlighted the need for future studies to explore ways to improve muscle strength and physical performance in older patients to potentially enhance their outcomes post-surgery.
Article Synopsis
- Manual muscle mass assessment via CT scans helps identify malnutrition and sarcopenia, but the process is labor-intensive and needs a more efficient automated method.
- This study involved 583 patients undergoing Transcatheter Aortic Valve Replacement (TAVR) to evaluate a deep learning-based method for automatically annotating psoas muscle areas, comparing it to manual analysis.
- Results showed the automated method had good accuracy and reliability, indicating it could be a valuable tool for larger studies on muscle mass without the extensive time commitment of manual analysis.
Cycling at Altitude: Lower Absolute Power Output as the Main Cause of Lower Gross Efficiency.
Int J Sports Physiol Perform
September 2019
Background: Although cyclists often compete at altitude, the effect of altitude on gross efficiency (GE) remains inconclusive.
Purpose: To investigate the effect of altitude on GE at the same relative exercise intensity and at the same absolute power output (PO) and to determine the effect of altitude on the change in GE during high-intensity exercise.
Methods: Twenty-one trained men performed 3 maximal incremental tests and 5 GE tests at sea level, 1500 m, and 2500 m of acute simulated altitude.
