Optimal time point for neutrophil-to-lymphocyte ratio to predict stroke-associated pneumonia.

Purpose: This study aimed at the population receiving thrombolytic therapy and to explore the optimal time point for neutrophil-to-lymphocyte ratio (NLR) in predicting stroke-associated pneumonia (SAP).

Methods: We assessed patients undergoing intravenous thrombolysis (IVT) for acute ischemic stroke. Blood parameters were sampled before thrombolysis (within 30 min after admission) and within 24-36 h after thrombolysis, respectively.

Delineating the Role of Mitophagy Inducers for Alzheimer Disease Patients.

Alzheimer's disease (AD) is the most common cause of dementia in elderly that serves to be a formidable socio-economic and healthcare challenge in the 21 century. Mitochondrial dysfunction and impairment of mitochondrial-specific autophagy, namely mitophagy, have emerged as important components of the cellular processes contributing to the development of AD pathologies, namely amyloid-β plaques (Aβ) and neurofibrillary tangles (NFT). Here, we highlight the recent advances in the association between impaired mitophagy and AD, as well as delineate the potential underlying mechanisms.

The Association Between Admission Anemia and Poststroke Depression.

Poststroke depression (PSD) is the most frequent and important neuropsychiatric problem afflicting these patients. Anemia is common in many of these individuals presenting with acute stroke. This study determined whether there is a relationship between anemia on hospital admission and PSD.

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.

Dysbiosis of lower respiratory tract microbiome are associated with inflammation and microbial function variety.

Background: Lower respiratory tract (LRT) microbiome has been reported to associate with pulmonary diseases. Unregulated inflammation is an underlying cause of variable lung diseases. The lung microbiome may play an important role in the smoking-induced inflammatory lung diseases.

Striatal overexpression of β-arrestin2 counteracts L-dopa-induced dyskinesia in 6-hydroxydopamine lesioned Parkinson's disease rats.

Prolonged administration of Levodopa (L-dopa) therapy can generate L-dopa-induced dyskinesia (LID). Accumulating evidence indicates that hyper-activation of the dopamine D1 receptor (D1R) and the cAMP signaling cascade in the medium spiny neurons (MSNs) of the striatum are involved in LID. Previous studies have shown that striatal β-arrestin2 overexpression significantly reduces LID severity and have indicated that β-arrestin2 may play a causal role in the dyskinesia sensitization process.

Effects of smoking on the lower respiratory tract microbiome in mice.

Background: Recent studies break with traditional opinion that the lower respiratory tract is sterile, and increasingly focus on the lung microbiome and disease. Smoking, as an important etiology of inflammatory lung disease, was considered as a factor influencing lung microbiome variations in our study, and we aimed to study the effect of smoking on inflammation and microbial diversity and community.

Methods: Forty male mice were selected and randomly divided into a smoking and a non-smoking group.

Role of sLOX-1 in intracranial artery stenosis and in predicting long-term prognosis of acute ischemic stroke.

Objective: The role of sLOX-1 in acute ischemic stroke still remains unclear. This study aims to demonstrate the value of sLOX-1 in evaluating degrees of intracranial artery stenosis and to predict prognosis in stroke.

Methods: Two hundred and seventy-two patients were included in this study and basic data were collected within 72 hr on admission.
