Enigma of social media use: complexities of social media addiction through the serial mediating effects of emotions and self-presentation.

Introduction: Excessive social media use, though considered unhealthy, is no longer formally categorized as an addiction or disorder, leading to a lack of consensus on this behavior. It raises concerns regarding the exclusion of Internet Addiction Disorder from the DSM-5-TR due to insufficient empirical evidence. This study investigates the serial mediating effects of positive and negative affect, fear of missing out, and offline and online self-presentation in the relationship between social media use and social media addiction.

Global prevalence of depression, anxiety, and stress symptoms in different trimesters of pregnancy: A meta-analysis and meta-regression.

The global prevalence of psychological problems in different trimesters is unclear due to methodological constraints in previous reviews. A precise estimate would be a key first step in raising awareness and allocating resources. This review aims to (1) calculate the global prevalence of depression, anxiety, and stress symptoms during different trimesters and (2) determine the factors influencing their prevalence estimates.

Whole genome analysis revealed the role of and genes in carbapenem resistance of strains.

is a multidrug-resistant bacterium that has emerged as a significant nosocomial pathogen globally and renowned for its ability to acquire antimicrobial resistance (AMR) genes. However, understanding of its resistance mechanisms to certain drug classes remains limited. This study focused on four bacterial strains (AB863, AB889, AB930, and AB960) exhibiting carbapenem resistance.

The Impact of Social Media on Children's Mental Health: A Systematic Scoping Review.

Background: In the digital age, safeguarding children's mental health (CMH) has emerged as one of the most pressing challenges. The rapid evolution of social media (SM) from a basic networking platform to a multifaceted tool has introduced numerous conveniences. However, it has also posed significant challenges to children's mental well-being.

A common form of dominant human IFNAR1 deficiency impairs IFN-α and -ω but not IFN-β-dependent immunity.

Autosomal recessive deficiency of the IFNAR1 or IFNAR2 chain of the human type I IFN receptor abolishes cellular responses to IFN-α, -β, and -ω, underlies severe viral diseases, and is globally very rare, except for IFNAR1 and IFNAR2 deficiency in Western Polynesia and the Arctic, respectively. We report 11 human IFNAR1 alleles, the products of which impair but do not abolish responses to IFN-α and -ω without affecting responses to IFN-β. Ten of these alleles are rare in all populations studied, but the remaining allele (P335del) is common in Southern China (minor allele frequency ≈2%).
