Summary
Identifying risk factors for poststroke falls and fractures is crucial. Age, previous falls, and atrial fibrillation increase risk, while certain strokes and higher disability scores may decrease it.
Area of Science:
- Neurology
- Geriatrics
- Public Health
Background:
- Poststroke falls and fractures are significant concerns with poorly understood risk factors.
- Identifying these risk factors is essential for improving patient outcomes and preventing secondary injuries.
Purpose of the Study:
- To evaluate demographic, stroke-related, and comorbid factors associated with increased risk of falls and fractures after stroke.
- To inform the development of targeted preventative strategies for poststroke complications.
Main Methods:
- Analysis of data from 7,267 hospitalized stroke patients (2003-2015).
- Utilized logistic regression and Cox-proportional hazard models for short-term and long-term follow-up (up to 10 years).
- Adjusted for multiple confounders including patient characteristics, stroke type, and comorbidities.
Main Results:
- 15.7% experienced falls and 9.2% sustained fractures over 10 years.
- Increased risk of falls and fractures associated with age, prior falls, and atrial fibrillation.
- Chronic kidney disease, hyperlipidemia, and prior stroke/TIA also linked to increased fall or fracture risk.
Conclusions:
- Demographic, stroke-specific, and comorbid factors significantly influence poststroke fall and fracture incidence.
- Further research is needed to explore reversible factors and preventative interventions.

01:05Free-falling Bodies: Example
32.8K
An object falling without any air resistance under the influence of gravitational force is said to be in free-fall. For free-falling bodies, the acceleration due to gravity is constant, irrespective of their mass. Free-fall is experienced not only by objects falling downward, but also by all objects whose motion is influenced by gravitational force alone. The dynamics of free-fall motion can be calculated using kinematic equations of motion, since free-fall acceleration is constant.

01:07Free-falling Bodies: Introduction
13.2K
All objects, neglecting air resistance, fall with the same acceleration towards the Earth's center due to the force exerted by the Earth's gravity. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavier ones. People believed that a heavier object had a greater acceleration when falling until Galileo Galilei (1564–1642) proved otherwise. We now know this is...

33.4K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

01:27Fractures: Bone Repair
5.6K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

82.9K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...
