AI Article Synopsis
- The study investigated how the Metabolic Score of Insulin Resistance (METS-IR) and uric acid (UA) levels relate to stroke risk, including the role of C-reactive protein (CRP) as a mediator.
- During a 9-year follow-up, increases in both METS-IR and UA were linked to a higher risk of stroke, with specific odds ratios indicating significant associations.
- CRP was found to mediate these relationships to some extent, and the combination of high METS-IR and UA resulted in the greatest risk for stroke among participants.
Article Abstract
Objectives: To explore the dose-response relationship between the Metabolic Score of Insulin Resistance (METS-IR), uric acid (UA) and the risk of stroke incidence, the mediating role of C-reactive protein (CRP) in the above relationship, as well as the joint effect of METS-IR and UA on the risk of stroke incidence.
Methods: Participants from the CHARLS study were included in this cohort study. Logistic regression models were used to estimate the odds ratios (ORs) and corresponding 95% confidence intervals (CIs) for the associations of METS-IR and UA with the risk of incident stroke. The dose-response relationships of METS-IR and UA with stroke risk were assessed by restricted cubic spline regression. The mediation models were employed to estimate the potential mediating effects of CRP on the associations of METS-IR and UA with stroke risk. Logistic regression analysis was carried out to analyse the association of stroke and MRTS-IR combined with UA.
Result: During a 9-year follow-up from 2011 to 2018, 570 incident cases of stroke were documented among 7,343 total participants. Per interquartile range increases in METS-IR and UA were associated with the increased risk of incident stroke, with the OR (95% CI) of 1.61 (1.44, 1.80) and 1.18 (1.05, 1.32) respectively. A dose-response function showed that METS-IR had a nonlinear relationship ( for nonlinear=0.047) and UA had a linear relationship ( for nonlinear=0.247) with the stroke risk. CRP had significant mediated effects on the associations of METS-IR and UA with stroke risk, and the proportion of mediation was 9.01% and 26.34% respectively (all < 0.05). The results of joint effect showed that participants with high levels of METS-IR and UA had the highest increased risk of stroke compared to the participants with low levels of METS-IR and UA.
Conclusion: METS-IR and UA levels were positively associated with an increased risk of stroke onset, and CRP mediated these relationships. Improving insulin sensitivity and regulating CRP and uric acid levels may be important for preventing the risk of stroke occurrence.

Background: The obesity paradox refers to lower mortality rates among overweight or obese individuals within certain populations. However, whether this paradox is applicable to patients undergoing percutaneous coronary intervention (PCI) remains unclear.
Methods: A total of 5,427 patients with coronary artery disease (CAD) who underwent successful PCI between 2005 and 2015 were enrolled.

Background And Objectives: Despite achieving ideal reperfusion (eTICI = 3) through endovascular treatment (EVT), some acute ischemic stroke (AIS) patients still experience poor outcomes. This study aims to evaluate the efficacy and safety of tirofiban in AIS patients with ideal reperfusion, focusing on its effects in large artery atherosclerosis (LAA) and cardioembolic (CE) stroke.
Methods: A total of 474 AIS patients from the RESCUE-BT database were included.

Max Planck Institute of Psychiatry, Munich, Germany.
Importance: As an accessible part of the central nervous system, the retina provides a unique window to study pathophysiological mechanisms of brain disorders in humans. Imaging and electrophysiological studies have revealed retinal alterations across several neuropsychiatric and neurological disorders, but it remains largely unclear which specific cell types and biological mechanisms are involved.
Objective: To determine whether specific retinal cell types are affected by genomic risk for neuropsychiatric and neurological disorders and to explore the mechanisms through which genomic risk converges in these cell types.
