Summary
Pre-stroke and in-hospital infections worsen outcomes for ischemic stroke (IS) patients. Preventing infections may improve prognosis, as antibiotic therapy during hospitalization did not show benefits in this study.
Area of Science:
- Neurology
- Infectious Diseases
- Clinical Research
Background:
- Infections are known risk factors for ischemic stroke (IS) incidence and prognosis.
- In-hospital infections can negatively impact stroke patient outcomes.
- The prevalence and specific effects of pre- and post-stroke infections require further elucidation.
Purpose of the Study:
- To investigate the prevalence of infections before and after ischemic stroke.
- To assess the impact of these infections on stroke severity and patient outcomes.
- To evaluate the influence of antibiotic therapy on outcomes in hospitalized IS patients.
Main Methods:
- Analysis of clinical data from 2066 ischemic stroke patients.
- Assessment of pre-stroke and post-stroke infections' effects on short-term (30-day) and long-term (90-day) outcomes.
- Logistic regression analysis to determine the independent impact of infections on poor outcomes (death/dependency).
Main Results:
- Pre-stroke infections were independently associated with poorer short-term outcomes.
- In-hospital infections correlated with worse short-term and long-term prognosis.
- Antibiotic treatment administered during hospitalization did not demonstrate a significant improvement in patient outcomes.
Conclusions:
- Preventing infections in ischemic stroke patients is crucial for improving prognosis.
- The efficacy of antibiotic therapy initiated after ischemic stroke warrants additional research.
- Early identification and management of infections are vital for better stroke care.

01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:29Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
01:17Ischemic Heart Disease: Overview
Ischemic heart disease occurs when the heart's blood supply dwindles, causing an ominous lack of oxygen and nutrients. This deficiency, stemming from reduced or obstructed blood flow, spells danger, leading to heart muscle damage and dysfunction.
Atherosclerosis, the primary malefactor, orchestrates this dangerous condition. It manifests as the accumulation of fatty deposits, akin to insidious plaques, within arterial walls. As time elapses, these plaques metamorphose, hardening and narrowing...

01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...
