Analysis and prediction of addiction among virtual reality users.

Objective: To understand the addiction situation and influencing factors of virtual reality users, and provide reference basis for timely and effective prevention and intervention of user addiction.

Methods: Based on a questionnaire survey, univariate analysis, multivariate analysis, and model prediction were conducted on the data of 1164 participants in VR related Facebook groups and Reddit subedits.

Results: The single factor analysis results show that the user's own attributes, usage duration, perception level, and application types of virtual reality devices can significantly affect the degree of addiction; The results of multivariate analysis showed that the age of users, the number of days used per week, the number of hours used per day, and the perceived level of the device can significantly affect the probability of addiction.

Macroscopically Self-Aligned and Chiralized Carbon Nanotubes: From Filtration to Innovation.

Because of their natural 1D structure combined with intricate chiral variations, carbon nanotubes (CNTs) exhibit various exceptional physical properties, such as ultrahigh thermal conductivity and diameter-dependent electrical behavior, ranging from semiconducting to metallic. While CNTs excel individually at the nanoscale, their 1D and chiral nature can be lost on a macroscopic scale when they are randomly assembled. Therefore, the alignment and organization of CNTs in macroscopic structures is crucial for harnessing their full potential.

Preconception body mass index is associated with the risk of spontaneous preterm birth among women with gestational diabetes: A retrospective cohort study.

Objective: Prior research efforts have not effectively clarified the relationship between preconception body mass index (BMI) and spontaneous preterm birth among women with gestational diabetes mellitus (GDM), particularly among Asian women. This study explores the relationship between pre-pregnancy BMI and spontaneous preterm birth among women with GDM, taking into account triacylglycerol (TG), glycated hemoglobin A1c (HbA1c), and gestational weight gain (GWG) levels.

Method: Data from 1116 women with GDM who produced singleton live births were retrospectively analyzed.

A cluster randomized controlled trial examining the effects of a four-week mindfulness-based practice on primary school students' interpersonal mindfulness, emotional intelligence, and attentional focus.

Background: Although mindfulness benefits are well-established across diverse populations, its impact on primary school children's interpersonal mindfulness, emotional intelligence, and attentional focus remains underexplored. This study evaluated the effectiveness of a four-week mindfulness-based practice (MBP) intervention among primary school students.

Methods: A cluster randomized controlled trial was conducted with 14 classes from Guanghua Elementary School, Taiwan.

Access to single-inhaler triple medicines for chronic obstructive pulmonary disease in China: a national survey on accessibility and utilisation.

Background: The maintenance medicines for chronic obstructive pulmonary disease (COPD) include inhaled corticosteroids (ICS), long-acting muscarinic antagonists (LAMA) and long-acting β2-agonists (LABA). Budesonide/glycopyrronium/formoterol (BUD/GLY/FOR) and fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) are two representative drugs for prefixed ICS/LAMA/LABA association in a single inhaler and have shown comparable efficacy and safety with other ICS/LAMA/LABA open combination therapies in patients with moderate-to-very severe COPD. This study aimed to investigate the availability, price, affordability, and utilisation of single-inhaler triple medicines for COPD in China.
