More than 12 million people around the world suffer a stroke every year, one every 3 s. Stroke has a variety of causes and is often the result of a complex interaction of risk factors related to age, genetics, gender, lifestyle, and some cardiovascular and metabolic diseases. Despite this evidence, it is not possible to prevent the onset of stroke. The use of innovative methods for metabolite analysis has been explored in the last years to detect new stroke biomarkers. We use NMR spectroscopy to identify small molecule variations between different stages of stroke risk. The Framingham Stroke Risk Score was used in people over 63 years of age living in long-term care facilities (LTCF) to calculate the probability of suffering a stroke. Using this parameter, three study groups were formed: low stroke risk (LSR, control), moderate stroke risk (MSR) and high stroke risk (HSR). Univariate statistical analysis showed seven metabolites with increasing plasma levels across different stroke risk groups, from LSR to HSR: isoleucine, asparagine, formate, creatinine, dimethylsulfone and two unidentified molecules, which we termed "unknown-1" and "unknown-3". These metabolic markers can be used for early detection and to detect increasing stages of stroke risk more efficiently.

Background: Cardiovascular diseases (CVD) remain a significant global health burden, particularly in China, where kidney dysfunction (KD) is a key risk factor. This study analyzed trends in the burden of KD-induced CVD and subtypes among the working-age population (25-64 years) in China over the past 30 years and explored its association with age, period, and birth cohort.
Methods: This study extracted data from the Global Burden of Disease (GBD) 2021, focusing on deaths and disability-adjusted life years (DALYs) caused by KD-induced CVD and subtypes, including ischemic heart disease (IHD), stroke, and lower extremity peripheral artery disease (LEPAD) among 25-64 years globally and in China from 1992 to 2021.
Clazosentan's dual edge in managing vasospasm following aneurysmal subarachnoid hemorrhage: an updated systematic review, meta-analysis, and meta-regression of clinical outcomes and safety profiles.

Aneurysmal Subarachnoid Hemorrhage (aSAH), resulting from ruptured aneurysms, is a major contributor to stroke-related mortality and morbidity. Despite advances in healthcare, aSAH remains severe and often leads to complications such as cerebral vasospasm (CV), cerebral infarction, and delayed ischemic neurological deficits (DIND). Clazosentan, an endothelin receptor antagonist, has demonstrated potential in alleviating vasospasm and its associated outcomes, although evidence of its efficacy remains unclear.

Cardiovascular disease (CVD) is the leading cause of death for women worldwide. One of the risk factors for CVD in women is complications during pregnancy. Pregnancy complications include a wide arena of pathologies, including hypertension, preeclampsia, gestational diabetes, preterm delivery and miscarriage.

A wide range of acute brain injuries, including both traumatic and non-traumatic causes, can result in elevated intracranial pressure (ICP), which in turn can cause further secondary injury to the brain, initiating a vicious cascade of propagating injury. Elevated ICP is therefore a neurological injury that requires intensive monitoring and time-sensitive interventions. Patients at high risk for developing elevated ICP undergo placement of invasive ICP monitors including external ventricular drains, intraparenchymal ICP monitors, and lumbar drains.

The opioid epidemic endangers not only public health but also social and economic welfare. Growing clinical evidence indicates that chronic use of prescription opioids may contribute to an elevated risk of ischemic stroke and negatively impact post-stroke recovery. In addition, NLRP3 inflammasome activation has been related to several cerebrovascular diseases, including ischemic stroke.
