Global trends, disparities, and future projections of ischemic stroke burden attributed to low-fiber diets: An analysis based on GBD 2021

OBJECTIVE

This study aims to analyze the disease burden attributed to ischemic stroke related to low-fiber diets (IFD-IS) from 1990 to 2021, utilizing data from the Global Burden of Disease (GBD) database to identify trends and influencing factors of the disease burden.

METHODS

We conducted a comprehensive analysis of the number of deaths, Disability-Adjusted Life Years (DALYs), Years of Life Lost (YLLs), and Years Lost due to Disability (YLDs) associated with IFD-IS, covering various regions and populations. Statistical methods, including breakpoint regression, decomposition analysis, health inequality analysis, and forecasting analysis, were employed to assess trends and their correlation with the Sociodemographic Index (SDI).

RESULTS

The findings indicate that deaths, DALYs, YLLs, and YLDs related to IFD-IS have gradually increased globally, with a significantly higher burden in males compared to females. Notable regional disparities were observed, particularly with heavier burdens in China and sub-Saharan Africa. Higher SDI regions demonstrated better control over disease burdens, while aging and population growth were the primary factors contributing to the increase. Additionally, the trend of health inequality related to IFD-IS has slightly diminished, although it is projected that the disease burden will continue to rise by 2040.

CONCLUSION

This study underscores the necessity of implementing targeted public health interventions for IFD-IS, particularly in low SDI regions. Enhancing dietary education and resource allocation can significantly mitigate the rising trend of IFD-IS. Ongoing monitoring and research are crucial for formulating effective health policies to address this public health challenge.

Running, walking, and cross-country skiing: how to shape adolescents' personalities through physical activity?

Adolescence is crucial for personality development, and sports play a significant role. This study investigates the impact of various sports on the personality traits of junior high and high school students in Shandong Province, focusing on neuroticism, extraversion, openness, agreeableness, and conscientiousness. Utilizing data from the "Database of Youth Health," we employed Seemingly Unrelated Regression (SUR) and Generalized Structural Equation Modeling (GSEM) to analyze the effects of physical activity on personality development. Findings reveal that walking significantly enhances openness and decreased neuroticism, while jogging/running substantially improves extraversion, agreeableness, and conscientiousness. Cross-country skiing, however, negatively impacts all assessed personality traits. In addition, the importance of gender differences in the relationship between physical activity and personality development was revealed. The results offer insights for promoting adolescent personality development through targeted sports activities.

Value and Variability of Pulse Shape Indicator for Estimating Mean Arterial Pressure in the Radial and Femoral Arteries

BACKGROUND

The form factor (FF) is a pulse shape indicator that corresponds to the fraction of pulse pressure added to diastolic blood pressure to estimate the time-averaged mean arterial pressure (MAP). Our invasive study assessed the FF value and variability at the radial and femoral artery levels and evaluated the recommended fixed FF value of 0.33.

METHODS AND RESULTS

Hemodynamically stable patients were prospectively included in 2 intensive care units. FF was documented at baseline and during dynamic maneuvers. A total of 632 patients (64±16 years of age, 66% men, MAP=81±14 mm Hg) were included. Among them, 355 (56%) had a radial catheter and 277 (44%) had a femoral catheter. The FF was 0.34±0.06. In multiple linear regression, FF was influenced by biological sex (P<0.0001) and heart rate (P=0.04) but not by height, weight, or catheter location. The radial FF was 0.35±0.06, whereas the femoral FF was 0.34±0.05 (P=0.08). Both radial and femoral FF were higher in women than in men (P<0.05). When using the 0.33 FF value to estimate MAP, the error was -0.4±4.0 mm Hg and -0.1±2.9 mm Hg at the radial and femoral level, respectively, and the MAP estimate still demonstrated high accuracy and good precision even after changes in norepinephrine dose, increase in positive end-expiratory pressure level, fluid administration, or prone positioning (n=218).

CONCLUSIONS

Despite higher FF in women and despite interindividual variability in FF, using a fixed FF value of 0.33 yielded accurate and precise estimations of MAP. This finding has potential implications for blood pressure monitoring devices and the study of pulse wave amplification.

[Russian eligibility criteria prescribing menopausal hormonal hormones therapy for patients with cardiovascular and metabolic diseases. Consensus document of the Russian Cardiological Society, Russian Society of Obstetricians and Gynecologists, Russian Association of Endocrinologists, Eurasian Association of Therapists, Association of Phlebologists of Russia]

Menopausal symptoms can disrupt the life course of women at the peak of their career and family life. Currently, the most effective treatment for these manifestations is menopausal hormone therapy (MHT). The presence of cardiovascular and metabolic diseases in itself does not exclude the possibility of prescribing MHT to relieve menopausal symptoms and improve quality of life. However, often an obstacle to the use of this type of hormonal therapy is the fear of doctors who are afraid of doing more harm to patients than good. Caution is especially important when it comes to women with underlying health conditions. Moreover, it should be recognized that there is a lack of high-quality research regarding the safety of MHT for major chronic non-infectious diseases and common comorbid conditions. The presented consensus document analyzed all currently available data obtained from clinical trials of various designs and created a set of criteria for the acceptability of prescribing MHT to women with concomitant cardiovascular and metabolic diseases. Based on the presented document, doctors of various specialties who advise women in menopause will receive an accessible algorithm that will allow them to avoid potentially dangerous situations and reasonably prescribe MHT in real practice.

Menopausal symptoms can impair the life of women at the peak of their career and family life. At the present time, the most effective treatment for these manifestations is menopausal hormone therapy (MHT). The presence of cardiovascular and metabolic diseases in itself does not exclude the possibility of prescribing MHT to relieve menopausal symptoms and improve quality of life. However, often an obstacle to the use of this type of hormone therapy is the fear of physicians to do more harm to patients than good. Caution is especially important when it comes to women with concurrent diseases. Moreover, it should be recognized that there is a shortage of high-quality research on the safety of MHT for underlying chronic non-infectious diseases and common comorbidities. The presented consensus analyzed all currently available data from clinical trials of various designs and created a set of criteria for the appropriateness of prescribing MHT to women with concomitant cardiovascular and metabolic diseases. Based on the presented document, physicians of various specialties who advise menopausal women will receive an accessible algorithm that will allow them to avoid potentially dangerous situations and reasonably prescribe MHT in real-life practice.
