Introduction: Stroke remains one of the leading causes of death and disability worldwide, with ischemic stroke accounting for most cases. Structural vascular factors such as carotid artery tortuosity have gained attention as potential markers of vascular aging and cerebrovascular risk. The carotid tortuosity index (CTI), defined as the ratio of actual vessel length to the straight-line distance between two fixed points, provides a quantitative measure of arterial curvature. A CTI value of ≥1.2 indicates pathological tortuosity. Although noninvasive modalities such as CTA and MRA are frequently used, digital subtraction angiography (DSA) remains the gold standard for evaluating vessel geometry due to its higher spatial precision. This study aimed to determine the association of age, sex, and hypertension with CTI measured by DSA. Methods: A cross-sectional study was conducted from November to December 2025 at the Neurointervention Clinic, RS Pelni Jakarta, Indonesia, involving 61 adult patients who underwent carotid DSA. CTI was measured bilaterally using digital imaging software and classified as <1.2 (non-tortuous) or ≥1.2 (tortuous). Clinical data, including age, sex, and hypertension status, were collected from medical records and analyzed using bivariate tests. Results: Older age (≥65 years), female sex, and hypertension were significantly associated with higher CTI values on both carotid sides. Tortuosity was more common among hypertensive patients and elderly females, indicating the influence of vascular remodeling and chronic hemodynamic stress. Conclusion: Carotid tortuosity increases with age, hypertension, and female sex. DSA-based CTI measurement provides a reliable and precise approach for evaluating vascular changes associated with cerebrovascular risk.

Background: Electronic cigarette (e-cigarette) use among adolescents is a growing public health concern, particularly in low-income and Black communities. However, little is known about how social determinants of health shape e-cigarette perceptions in this population. Aims: This study examined social determinants associated with perceptions of e-cigarette safety among Baltimore high school students. Methods: A cross-sectional survey (CEASE Youth: School Survey) was conducted with 604 Baltimore high school students aged 14–20. Participants completed a questionnaire assessing perceptions of e-cigarette safety, as well as parental education, race/ethnicity, parental employment, household composition, and community tobacco use. Results: Higher parental education was associated with lower perceived e-cigarette safety among students. Students in higher grades also reported lower perceived e-cigarette safety. In contrast, male students—particularly those in upper grades—were more likely to perceive e-cigarettes as safe. Race/ethnicity, household composition, parental employment, and community tobacco exposure were not associated with perceived e-cigarette safety. Conclusion: Higher parental education, female gender, and being in higher grades were associated with perceiving e-cigarettes as unsafe. These findings highlight the need for targeted interventions to address vaping perceptions among youth in urban settings.

The anterior collateral ligament (ACL) is one of four ligaments in the knee, connecting the tibia and femur and acting as a key stabilizer. Factors influencing these injuries include playing surface, training programs, athlete strength, technique, and gender. Female athletes are at a higher risk of ACL injuries, being four to nine times more likely than males, often due to differences in biomechanics and training patterns. It ss important that rehab focuses on both legs, as overworking the injured leg increases the risk of injuries elsewhere. Prevention training, such as proprioceptive-balance and plyometric agility training, has been shown effectiveness in minimizing ACL injuries. Despite some limitations in research, these programs highlight the importance of improved training techniques. Kinesio taping might help reduce pain but lacks strong evidence for preventing ACL tears.

Background: Women have consistently shown lower quit rates in tobacco cessation programs compared to men. This gender disparity persists despite comprehensive interventions and access to cessation resources. While prior studies suggest that factors such as social support, chronic disease burden, and socioeconomic status may contribute to these differences, there is limited empirical evidence to confirm these mechanisms. Aims: This study aimed to investigate potential mechanisms underlying gender differences in quit rates in a tobacco cessation program, testing whether demographic, socioeconomic, health, or behavioral factors explain the observed disparities. Methods: Participants were assigned to one of three smoking cessation interventions: an in-person program (CEASE), a self-help approach, or an online/hybrid program. The main outcome measured was smoking abstinence, evaluated three months after the intervention. Secondary analyses explored whether demographic, socioeconomic, health, or tobacco use-related factors mediated the association between gender and quit rates. Results: Women had significantly lower quit rates than men (p < 0.01). This association remained significant after adjusting for demographic, socioeconomic, health, and addiction-related factors. While women reported higher social support and a higher prevalence of chronic cardiometabolic conditions, these factors did not explain the gender disparity in quit rates. Conclusions: Gender differences in quit rates persist despite controlling for known factors that could influence cessation success. Although women had higher social support, they had lower quit rate. Future research should explore unmeasured variables, such as psychological, biological, and structural influences, to develop more effective cessation strategies tailored for women.
