Muscle Recovery and Fatigue01:24

Muscle Recovery and Fatigue

4.1K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Regulation of Stroke Volume01:27

Regulation of Stroke Volume

4.9K
The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Improving Translational Accuracy

14.1K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Cardiac Output and Stroke Volume01:11

Cardiac Output and Stroke Volume

4.6K
Cardiac output (CO) is an integral aspect of human physiology, reflecting the heart's efficiency and responsiveness to the body's needs. It represents the volume of blood that the left or right ventricle ejects into the aorta or pulmonary trunk each minute. The CO is calculated by multiplying the heart rate (HR)—the number of heartbeats per minute—by the stroke volume (SV)—the amount of blood pumped out with each heartbeat.
In an average resting adult male, the typical cardiac...

Cardiac Output II: Effect of Stroke Volume on Cardiac Output01:22

Cardiac Output II: Effect of Stroke Volume on Cardiac Output

3.3K
Cardiac output (CO), the amount of blood the heart pumps per minute, is a parameter in cardiovascular physiology determined by stroke volume and heart rate. Stroke volume, the amount of blood pushed from one of the ventricles per heartbeat, is influenced by preload, afterload, and contractility.
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...

Summary

Fluoxetine, an antidepressant, did not improve functional recovery in patients following acute stroke. This large clinical trial found no significant benefit for patients taking fluoxetine compared to placebo.

Area of Science:

  • Neurology
  • Clinical Trials
  • Pharmacology

Background:

  • Stroke is a leading cause of long-term disability.
  • Functional recovery after stroke is a critical area for therapeutic intervention.
  • Antidepressants are sometimes used off-label to potentially aid stroke recovery.

Purpose of the Study:

  • To investigate the efficacy of fluoxetine in improving functional outcomes after acute stroke.
  • To determine if early administration of fluoxetine impacts recovery trajectories.

Main Methods:

  • A pragmatic, double-blind, randomized, controlled trial involving patients after acute stroke.
  • Participants received either fluoxetine or a placebo.
  • Functional outcomes were assessed over a defined period.

Main Results:

  • No statistically significant difference in functional outcomes was observed between the fluoxetine group and the placebo group.
  • The study found no evidence that fluoxetine enhances recovery after stroke.
  • Adverse events were monitored and reported.

Conclusions:

  • Early treatment with fluoxetine does not improve functional outcomes for patients recovering from acute stroke.
  • The findings do not support the use of fluoxetine for enhancing stroke recovery.
  • Further research may explore other therapeutic strategies for post-stroke rehabilitation.
