This study applied alterations in partial pressure of end-tidal carbon dioxide ( ) to challenge dynamic cerebral autoregulation (dCA) responses across the cardiac cycle in both biological sexes. A total of 20 participants (10 females and 10 males; aged 19-34 years) performed 4-min bouts of repeated squat-stand manoeuvres (SSMs) at 0.05 and 0.

- There are different opinions on how high the frequency cut-off point of dynamic cerebral autoregulation (CA) is, with one method suggesting it's around 0.07 Hz and another saying it could be as high as 0.24 Hz.
- A study looked at how these limits are accurate by having 16 people perform squat-stand exercises at different frequencies while measuring blood flow in their brains.
- The results showed that while there were some differences between males and females, the overall upper frequency limit for CA was similar regardless of sex, the type of blood vessel, or the heartbeat phase.
Background: Concussion education is recommended to increase concussion knowledge, beliefs, and reporting intentions. The Concussion Awareness Training Tool for Youth (CATT-Youth) is a 40-minute e-Learning module developed for high school-aged youth.
Aim: The aim of the study was to evaluate changes in concussion knowledge, beliefs, and reporting intentions in high school youth from Calgary, Canada, following completion of the CATT-Youth.
Cerebral hemodynamics have been quantified during exercise via transcranial Doppler ultrasound, as it has high-sensitivity to movement artifacts and displays temporal superiority. Currently, limited research exists regarding how different exercise modalities and postural changes impact the cerebrovasculature across the cardiac cycle. Ten participants (4 females and 6 males) ages 20-29 completed three exercise tests (treadmill, supine, and upright cycling) to volitional fatigue.

Progressive knee pain over three years with a negative PJI infectious workup led to revision total knee arthroplasty. A surprising result was isolation of Mycobacterium avium from tissue cultures taken at time of revision surgery.
