Background: Numerous studies have shown that insulin resistance (IR) is closely related to the pathogenesis of cardiovascular disease (CVD). This study aims to summarize the correlation between the triglyceride-glucose-body mass index (TyG-BMI index), a novel surrogate indicator of insulin resistance, and the incidence of CVD in patients without CVD at baseline through meta-analysis.
Method: Cohort studies assessing multivariate-corrected hazard ratios (HRs) for associations between the TyG-BMI index and cardiovascular disease (CVD) were obtained by searching PubMed, Cochrane Library, EMBASE, and Web of Science. Results were combined using a random-effects model to account for heterogeneity among the included studies. Robust error meta-regression was used to fit the nonlinear dose-response relationship. Statistical analysis was performed using Review Manager 5.4 and STATA 18.0.
Result: Ten cohort studies involving a total of 871,728 subjects were included. The results indicated that Compared with the lowest TyG-BMI index category, the highest TyG-BMI index was related to a higher incidence of cardiovascular diseases (CVD) (HR = 1.62; 95% confidence interval (CI): 1.35-1.95; I = 94%),coronary artery disease (CAD) (HR = 1.69; 95% (CI): 1.23-2.31; I = 94%). stroke(HR = 1.57; 95% (CI): 1.11-2.23; I = 94%).In the dose-response analysis, there was a linear association of the TyG-BMI index with the risk of CVD (P = 0.223), CAD (P = 0.693), and stroke (P = 0.122)No significant effects were observed regarding participants' gender, length of follow-up, sample size or mean age(P > 0.05).
Conclusion: Higher TyG-BMI may be independently associated with an increased risk of CVD in individuals without CVD at baseline. Numerous cohort studies are needed to further validate and elucidate the pathologic role between Tyg-BMI and CVD and to determine whether it can be incorporated into CVD risk prediction tools to enhance predictive accuracy.

Purpose Of Review: Diagnostic stewardship (DS) aims to optimise the use of laboratory testing to improve patient care while reducing unnecessary tests. This review examines recent evidence on DS interventions to optimise the use of resources, focusing on three key areas: reducing unnecessary testing, maximising the impact of existing tests, and avoiding the overdiagnosis of hospital-acquired infections.
Recent Findings: Multiple interventions have demonstrated effectiveness in reducing unnecessary blood and urine culture testing, including clinical decision support tools, education programs, and multidisciplinary approaches.

Background: With the availability of more advanced and effective treatments, life expectancy has improved among patients with metastatic breast cancer (MBC), but this makes communication with their medical oncologist more complex. Some patients struggle to learn about their therapeutic options and to understand and articulate their preferences. Mobile health (mHealth) apps can enhance patient-provider communication, playing a crucial role in the diagnosis, treatment, quality of life, and outcomes for patients living with MBC.

We estimated linear mixed-effects models to analyze changes in language patterns (as measured using Linguistic Inquiry and Word Count) among neurodiverse youth to introduce a novel assessment useful for research into the potential benefits of special interests while minimizing respondent and researcher burden.

Background: Digital media frequently contains positive portrayals of alcohol content, which has been shown to be associated with alcohol-related cognitions and behaviors. Because youth are heavy media consumers and have access to unsupervised, repeat viewing of media content on their personal mobile devices, it is critical to understand the frequency of encountering alcohol content in adolescents' daily lives and how adolescents engage with the content.
Objective: This paper outlines the study protocol for examining adolescents' exposure to alcohol-related content in digital media within their natural environments.

Importance: Exposure to fine particulate matter air pollution (PM2.5) may increase risk for dementia. It is unknown whether this association is mediated by dementia-related neuropathologic change found at autopsy.
