Individualized predictions of early isolated distal deep vein thrombosis in patients with acute ischemic stroke: a retrospective study.

Background: Although isolated distal deep vein thrombosis (IDDVT) is a clinical complication for acute ischemic stroke (AIS) patients, very few clinicians value it and few methods can predict early IDDVT. This study aimed to establish and validate an individualized predictive nomogram for the risk of early IDDVT in AIS patients.

Methods: This study enrolled 647 consecutive AIS patients who were randomly divided into a training cohort (n = 431) and a validation cohort (n = 216).

Hemostasis functions are associated with hemorrhagic transformation in non-atrial fibrillation patients: a case-control study.

Background: Hemorrhagic transformation (HT) is a serious neurological complication of acute ischemic stroke (AIS) after revascularization. The majority of AIS patients do not have atrial fibrillation (AF) which could also develop into HT. In this study, we aimed to explore whether hemostasis parameters are risk factors of HT in non-AF patients.

Cardiac parameters affect prognosis in patients with non-large atherosclerotic infarction.

This was the first prospective study aimed to compare the prevalence of PSD and its symptoms between two cohorts of patients with acute ischemic stroke (AIS) and intracerebral hemorrhage (ICH).

Methods: Both AIS and ICH patients were simultaneously enrolled in the study.

Liver Fibrosis Is Associated With Hemorrhagic Transformation in Patients With Acute Ischemic Stroke.

Hemorrhagic transformation (HT) is a frequent, often asymptomatic event that occurs after acute ischemic stroke (AIS). Liver fibrosis, usually subclinical, is common and crucial in the development of liver disease. We aimed to investigate the association between liver fibrosis and HT in patients with AIS.

The Advantages of Levodopa-Carbidopa Intestinal Gel for Patients with Advanced Parkinson's Disease: A Systematic Review.

Background: Levodopa-carbidopa intestinal gel (LCIG) is a new type of administration that results in steadier levodopa plasma concentrations in advanced Parkinson's disease (PD) patients and effectively reduces poor mobility and dyskinesia.

Methods: Electronic databases were searched up to January 1, 2018. The inclusion criteria for this review were as follows: LCIG vs oral medication in advanced PD patients.

β-arrestin2 alleviates L-dopa-induced dyskinesia via lower D1R activity in Parkinson's rats.

The cause of the L-dopa-induced dyskinesia (LID) has been ascribed to G-protein coupled receptor (GPCR) supersensitivity and uncontrolled downstream signaling. It is now supposed that β-arrestin2 affects GPCR signaling through its ability to scaffold various intracellular molecules. We used the rAAV (recombinant adeno-associated virus) vectors to overexpress and ablation of β-arrestin2.

However, the efficacy of therapies that lower homocysteine concentrations in reducing the risk of CVD and stroke remains controversial. Our objective was to do a meta-analysis of relevant randomized controlled trials (RCTs) to evaluate the efficacy of folic acid supplementation among patients with hypertension and Hyperhomocysteinemia (HT/HHcy).

Derivation and Validation of a Clinical Prediction Scale for Isolated Distal Deep Venous Thrombosis in Patients after Acute Ischemic Stroke.

Background: Isolated distal deep venous thrombosis (IDDVT) is a common complication after ischemic stroke. However, there is a paucity of evidence regarding the clinical features and risk factors of IDDVT in patients with acute ischemic stroke. This study aimed to establish and validate a clinical prediction scale of IDDVT at an early stage of ischemic stroke development.

Association between DβH 5'-insertion/deletion polymorphism and cognition in patients with chronic schizophrenia.

Background: Cognitive deficits have been identified as a core feature of patients with schizophrenia. Many genes associated with the dopamine and norepinephrine systems are related to the cognitive deficits of patients with schizophrenia. Dopamine β-hydroxylase (DβH) is a key enzyme that converts dopamine to norepinephrine and for which activity and levels are under strong genetic control.

TCF4 gene polymorphism is associated with cognition in patients with schizophrenia and healthy controls.

Background: Cognitive deficits have been identified as an important core feature of schizophrenia. Single nucleotide polymorphisms in the transcription factor 4 (TCF4) gene have been reported to be involved in the susceptibility to schizophrenia and be significantly related to cognitive deficits of schizophrenia and controls. This study examines whether the TCF4 rs2958182 polymorphism influences cognitive functions in chronic schizophrenia and controls.

Association of angiotensin-converting enzyme gene polymorphism with schizophrenia and depressive symptom severity in a Chinese population.

Background: Depressive symptoms are frequently observed in schizophrenia patients. Angiotensin-converting enzyme (ACE), a key enzyme of renin-angiotensin system, can catalyze the degradation of neuropeptides and modulate dopaminergic and serotonergic neurotransmission. Previous studies have revealed the association of the ACE gene insertion/deletion polymorphism with depressive disorder and its treatment response but not with the depressive symptoms in schizophrenia.

Possible association between DBH 19 bp insertion/deletion polymorphism and clinical symptoms in schizophrenia with tardive dyskinesia.

Overactivity of dopaminergic neurotransmission is a putative mechanism of tardive dyskinesia (TD). Previous studies have found dysfunction in plasma dopamine beta-hydoxylase (DBH) in schizophrenia with TD. Moreover, DBH, whose activity and levels are strongly controlled by the DBH gene, is a key enzyme in the conversion of dopamine (DA) to norepinephrine (NE) associated with excited behavior.
