Impact of Concurrent Ischaemic Stroke on Unfavourable Outcomes in Men and Women with Dilated Cardiomyopathy.

Background: Growing evidence suggests that concurrent ischaemic stroke (IS) exacerbates the prognosis of patients with dilated cardiomyopathy (DCM) and that this effect may be further influenced by sex. However, the exact effect of sex remains unclear. This study aimed to explore the effects of the relevant risk factors on the prognosis of patients with DCM and concurrent IS.

A Bayesian network-based approach for identifying risk factors and predicting ischemic stroke in infective endocarditis patients.

Objective: This study aimed to seek the risk factors and develop a predictive model for ischemic stroke (IS) in patients with infective endocarditis (IE) utilizing a Bayesian network (BN) approach.

Methods: Data were obtained from the electronic medical records of all adult patients at three hospitals between 1 January 2018, and 31 December 2022. Two predictive models, logistic regression and BN, were used.

Risk factors assessment and a Bayesian network model for predicting ischemic stroke in patients with cardiac myxoma.

Objective: This study aims to identify relevant risk factors, assess the interactions between variables, and establish a predictive model for ischemic stroke (IS) in patients with cardiac myxoma (CM) using the Bayesian network (BN) approach.

Methods: Data of patients with CM were collected from three tertiary comprehensive hospitals in Beijing from January 2002 to January 2022. Age, sex, medical history, and information related to CM were extracted from the electronic medical record system.

Clinical features, risk factors and survival in cardiac myxoma-related ischemic stroke: A multicenter case-control study.

Background: Cardiac myxoma (CM) is an important etiology of stroke in young adults, but studies on CM-related ischemic stroke (CM-IS) are limited and conflicting. Hence, we investigated clinical characterizations, risk factors of CM-IS, and short-term survival after surgical resection.

Methods: We performed a retrospective analysis of data from all CM patients at three referral management centers and conducted follow-up examination.

Risk factors and a Bayesian network model to predict ischemic stroke in patients with dilated cardiomyopathy.

Objective: This study aimed to identify risk factors and create a predictive model for ischemic stroke (IS) in patients with dilated cardiomyopathy (DCM) using the Bayesian network (BN) approach.

Materials And Methods: We collected clinical data of 634 patients with DCM treated at three referral management centers in Beijing between 2016 and 2021, including 127 with and 507 without IS. The patients were randomly divided into training (441 cases) and test (193 cases) sets at a ratio of 7:3.

A near-infrared fluorescent probe for detecting copper(II) with high selectivity and sensitivity and its biological imaging applications.

The first near-infrared fluorescent probe was developed toward Cu(2+). Based on the photo-induced electron transfer (PET) mechanism, the probe exhibited weak fluorescence. Upon the addition of Cu(2+), it fluoresced strongly.

Increased CD8+ central memory T cells in patients with multiple sclerosis.

A T-cell-mediated autoimmune process against central nervous system myelin is believed to underlie the pathogenesis of multiple sclerosis (MS). Formation of immunological memory is based on the differentiation of naïve T cells to memory T cells after exposure to antigens and specific cytokines. The aim of this study was to analyse peripheral blood mononuclear cells in patients with MS for different T-cell subsets including naïve and memory T cells.

[Influence of beta-endorphin on function of immune system of patients with cerebral hemorrhage].

Objective: To study the influence of beta-endorphin (beta end) on the function of immune system of patients with cerebral hemorrhage at different stages.

Methods: Radioimmunal analysis was applied to detect the serum beta-endorphin concentration in the peripheral blood of 28 patients with cerebral hemorrhage, aged 65.5 +/- 13, 28 age-matched patients with cerebral thrombosis, and 28 sex and age-matched normal controls.
