Summary
Skiing can cause acute ischemic stroke (AIS), often due to arterial dissection, even with minor falls. This study analyzed skiing-associated strokes (SASs) and found dissection was more common than in non-skiing stroke patients.
Area of Science:
- Neurology
- Sports Medicine
- Public Health
Background:
- Previous studies on stroke triggers are limited, with only one series linking downhill skiing to cervical artery dissections.
- This study focuses on acute ischemic stroke (AIS) temporally associated with ski practice, examining frequency, pathogenesis, clinical presentation, and prognosis.
Purpose of the Study:
- To investigate the characteristics of acute ischemic stroke (AIS) occurring after skiing.
- To determine the frequency, causes, and outcomes of skiing-associated strokes (SASs).
Main Methods:
- A prospective registry of Skiing Associated Strokes (SASs) was maintained from 2003 to 2017.
- A comparison group of non-SAS patients was identified from the Acute Stroke Registry and Analysis of Lausanne (ASTRAL) and matched for age and gender.
Main Results:
- 17 SASs were identified over 12 years, with arterial dissection being the primary cause in 65% of cases, significantly higher than in controls (14%).
- Minor or moderate skiing trauma preceded most SAS cases involving arterial dissection.
- Other stroke mechanisms included cardiac embolism and atherosclerosis.
Conclusions:
- Arterial dissection is a more frequent stroke mechanism in skiing-associated strokes (SASs) compared to matched controls.
- Minor to moderate skiing-related trauma is often associated with SASs caused by arterial dissection.

02:24Predicting Reaction Outcomes
10.8K
Kinetics describes the rate and path by which a reaction occurs. In contrast, thermodynamics deals with state functions and describes the properties, behavior, and components of a system. It is not concerned with the path taken by the process and cannot address the rate at which a reaction occurs. Although it does provide information about what can happen during a reaction process, it does not describe the detailed steps of what appears on an atomic or a molecular level. On the other hand,...

01:13Outcomes of Glycolysis
107.2K
Nearly all the energy used by cells comes from the bonds that make up complex organic compounds. These organic compounds are broken down into simpler molecules, such as glucose. As a result, cells extract energy from glucose over many chemical reactions—a process called cellular respiration.
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate...

01:11Guidelines for Writing Outcome
3.9K
When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

01:27Regulation of Stroke Volume
5.2K
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...

01:11Cardiac Output and Stroke Volume
4.9K
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.

01:27Open Angle Glaucoma: Treatment
997
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
