Efficacy of an eHealth self-management program in reducing irritable bowel syndrome symptom severity: a randomized controlled trial.

This study aimed to verify whether an eHealth-based self-management program can reduce irritable bowel syndrome (IBS) symptom severity. An open-label simple randomized controlled trial was conducted that compared an intervention group (n = 21) participating in an eHealth self-management program, which involved studying IBS-related information from an established self-help guide followed by in-built quizzes, with a treatment-as-usual group (n = 19) that, except for pharmacotherapy, had no treatment restrictions. Participants were female Japanese university students.

Development and Validation of a Japanese-Language Questionnaire to Screen for Tension-Type Headaches and Migraines.

Introduction Migraine and tension-type headache (TTH) are chronic diseases associated with significant socioeconomic losses and social and psychological impact (current global prevalence: 10% and 38%, respectively). Thus, they require accurate identification and classification. In clinical practice, validated screening tools able to quickly determine migraine and TTH with high sensitivity and specificity help provide an objective and multifaceted understanding of patients' headache symptoms.

Slow spectral diffusion of the NO stretching mode of [RuCl(NO)] in DO studied by 2D-IR spectroscopy and molecular dynamics simulations.

The vibrational dynamics of the NO stretching mode of [RuCl(NO)] in DO were investigated by nonlinear infrared (IR) spectroscopy. We performed IR pump-probe measurements to obtain the vibrational lifetime of this molecule. The lifetime is 31 ps, which is sufficiently long enough to study the vibrational frequency fluctuation on a slower time scale with high precision.

Prevalence of Irritable Bowel Syndrome in Japan, China, and South Korea: An International Cross-sectional Study.

Background/aims: Symptoms of irritable bowel syndrome (IBS), a common gut-brain interaction disorder, deteriorate patients' quality of life and increase medical needs; therefore, IBS represents a significant global burden. The estimated global prevalence is approximately 10%; however, accumulated evidence shows international heterogeneity. In this study, we have described and compared the prevalence of IBS in 3 East Asian countries: Japan (Tokyo and Fukuoka), China (Beijing), and South Korea (Seoul).
