Role of frailty in predicting outcomes after stroke: a systematic review and meta-analysis.

Background: Stroke is considered the second most common cause of death and the third leading cause of disability worldwide. Frailty, characterized by increased vulnerability to stressors, is emerging as a key factor affecting outcomes in older adults and stroke patients. This study aimed to estimate the prevalence of frailty in acute stroke patients and assess its association with mortality and poor functional outcome.

APAview: A web-based platform for alternative polyadenylation analyses in hematological cancers.

Hematologic malignancies, such as acute promyelocytic leukemia (APL) and acute myeloid leukemia (AML), are cancers that start in blood-forming tissues and can affect the blood, bone marrow, and lymph nodes. They are often caused by genetic and molecular alterations such as mutations and gene expression changes. Alternative polyadenylation (APA) is a post-transcriptional process that regulates gene expression, and dysregulation of APA contributes to hematological malignancies.

The alleles of AGT and HIF1A gene affect the risk of hypertension in plateau residents.

Plateau essential hypertension is a common chronic harmful disease of permanent residents in plateau areas. Studies have shown some single nucleotide polymorphisms (SNPs) associations with hypertension, but few have been verified in plateau area-lived people. In this paper, we examined some hypertension-related gene loci to analyze the relationship between risk SNPs and plateau essential hypertension in residents in Qinghai-Tibet plateau area.

Pharmacological Targets and the Biological Mechanisms of Formononetin for Alzheimer's Disease: A Network Analysis.

BACKGROUND This study aimed to identify the pharmacological targets and mechanisms of action of the traditional Chinese medicine, formononetin, in the treatment of Alzheimer's disease (AD) using network pharmacological analysis. MATERIAL AND METHODS Targets of AD were obtained by using DisGeNET gene discovery platform, the herbal ingredients target (HIT) database, the SuperPred, and the SwissTargetPrediction compound target prediction platforms. Pathogenic and therapeutic targets were imported to the STRING biological database, and Cytoscape network integration software was used to construct component-target and disease-target interaction networks.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy: Phenotypic and mutational spectrum in patients from mainland China.

Aims: To analyze the NOTCH3 gene mutations in patients from mainland China clinically suspected to have cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) and evaluate large intracranial arteries in CADASIL patients.

Methods: We performed clinical, neuroimaging and NOTCH3 gene (exons 2-23) examinations in 47 subjects from 34 families. Large intracranial arteries were assessed using magnetic resonance angiography (MRA) in 19 cases with NOTCH3 gene variants.

Increased visibility of deep medullary veins in leukoaraiosis: a 3-T MRI study.

Cerebral venous collagenosis has been implicated in leading to white matter hyperintensities (WMHs) via venous ischemia. We sought to determine whether cerebral venous dilation or ischemia correlate with the severity of WMHs by quantitative in vivo imaging techniques. This was an investigator-initiated prospective single-center study.

[Risk factors of hemorrhagic transformation in different locations and its relation to clinical outcomes of patients with acute ischemic stroke following intravenous thrombolysis].

Objective: To investigate the risk factors of hemorrhagic transformation (HT) in different cerebral regions and to explore its relation to clinical outcomes of patients with acute ischemic stroke after intravenous thrombolysis therapy.

Methods: The clinical, laboratory, and radiological data of 292 consecutive acute ischemic stroke patients undergoing intravenous thrombolysis therapy in Second Affiliated Hospital, Zhejiang University School of Medicine from June 2009 to May 2013 was retrospectively analyzed. Deep HT was defined as HT located in basal ganglia, internal capsule, external capsule and thalamus, otherwise the lesion was defined as non-deep HT.

[Impact of atrial fibrillation on clinical outcome in patients with acute ischemic stroke undergoing thrombolytic therapy].

Objective: To investigate the impact of atrial fibrillation (AF) on clinical outcomes in patients with acute ischemic stroke undergoing thrombolytic therapy.

Methods: The clinical data of 330 patients with acute ischemic stroke who received intravenous recombinant tissue plasminogen activator (rt-PA) therapy in the Second Affiliated Hospital, Zhejiang University School of Medicine between June 2009 and August 2013 were reviewed. Clinical outcomes in AF and non-AF groups were evaluated by univariate and multivariate analysis.

[Impact of cerebral microbleeds on outcomes of acute ischemic stroke treated with intravenous thrombolysis].

Objective: To assess the impact of cerebral microbleeds (CMBs) on clinical outcomes in patients with acute ischemic stroke treated by intravenous thrombolysis.

Methods: The clinical data of 225 patients with acute ischemic stroke who received intravenous recombinant tissue plasminogen activator therapy in the Second Affiliated Hospital, Zhejiang University School of Medicine from June 2009 to May 2013 were reviewed. The severity of CMBs and hemorrhagic transformation (HT) after thrombolytic therapy and clinical neurological outcome based on modified Rankin scale (mRS) at 3 months were evaluated.
