Article Abstract

Autonomous sensory meridian response (ASMR) is a sensory-emotional phenomenon characterized by distinct tingling sensations and a sense of relaxation induced by specific auditory and visual stimuli. Although ASMR is recognized as a cross-modal experience, psychological and physiological mechanisms behind ASMR remain only partially understood. Across two experiments, we investigated these mechanisms. Experiment 1 showed that ASMR videos with combined audiovisual content elicited stronger tingling sensations than those with auditory-only content, suggesting an additive effect through sensory processing. In Experiment 2, we measured responses to ASMR and nature videos using finger photoplethysmography (PPG) and found that both types of videos reduced pulse rates compared to rest. Notably, ASMR videos caused a greater reduction in pulse rate than nature videos. These findings are discussed in relation to autonomic nervous system activation, cross-modal interactions, and the social grooming hypothesis, which posits that ASMR may replicate comforting effects of social bonding behaviors, such as grooming.

Background: Ectopic pregnancy (EP) represents a leading cause of maternal mortality in early gestation and a significant contributor to future reproductive impairment. Comprehensive understanding of global EP epidemiological patterns and their temporal evolution is crucial for developing holistic strategies to promote health equity and optimize allocation of medical resources worldwide.

Methods: Leveraging Global Burden of Disease (GBD) 2021 data, this investigation systematically examined age-standardized rates (ASRs) of EP incidence, prevalence, mortality, and disability-adjusted life years (DALYs) across 204 countries and 21 regions from 1990 to 2021.

Objective: To evaluate the burden and trends of digestive system cancers in adolescents and young adults (AYAs) globally between 1990 and 2021.

Methods: Data were extracted from the Global Burden of Diseases, Injuries, and Risk Factors Study (1990-2021). We analyzed global, regional, and national disease burdens by calculating the age-standardized incidence (ASIR), mortality (ASMR), and disability-adjusted life years (DALYs) for AYAs.

Objective: The incidence of inflammatory bowel disease (IBD) peaks between the ages of 15 and 40. This age range coincides with women of childbearing age (WCBA), who face unique challenges like adverse pregnancy outcomes and heightened anxiety. Despite the rising global prevalence of IBD, particularly among younger populations, the burden of IBD among women, especially WCBA, remains underexplored.

Background: Ovarian cancer remains the most lethal gynecological cancer, with fewer than 50% of patients surviving more than five years after diagnosis. This study aimed to analyze the global epidemiological trends of ovarian cancer from 1990 to 2021 and also project its prevalence to 2050, providing insights into these evolving patterns and helping health policymakers use healthcare resources more effectively.

Methods: This study comprehensively analyzes the original data related to ovarian cancer from the GBD 2021 database, employing a variety of methods including descriptive analysis, correlation analysis, age-period-cohort (APC) analysis, decomposition analysis, predictive analysis, frontier analysis, and health inequality analysis.

Aim: This study aimed to analyze the disease burden of carbon monoxide poisoning (COP) in China from 1990 to 2021 and to forecast future trends.

Methods: Data were retrieved from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021. The incidence, prevalence, mortality, and Disability Adjusted Life Years (DALYs) and their corresponding Age-Standardized Rates (ASRs) were examined to assess the burden of COP in China from 1990 to 2021.
