Social Anxiety and Peer Victimization and Aggression: Examining Reciprocal Trait-State Effects among Early Adolescents.

As peer relationships become paramount during early adolescence, there's a normative rise in social anxiety, coinciding with a peak in peer victimization and aggression. Although previous studies have suggested reciprocal associations between changes in social anxiety and adolescent peer victimization and aggression, the mechanics of these associations at the personal trait and time-varying state levels remains unclear. This study examined the longitudinal relations between social anxiety and adolescent peer victimization and aggression by disentangling between-person trait differences from within-person state processes.

Brown Slime Cap Mushroom (Chroogomphus rutilus, Agaricomycetes) Polysaccharide Resists Motion Sickness by Inhibiting the Activity of the Serotonin System in Mice.

Motion sickness (MS) is a disorder of the autonomic nervous system caused by abnormal exercise with symptoms such as nausea, vomiting and drowsiness. More than 90% of the human population has experienced different degrees of MS. At present, anticholinergics, antihistamines, and sympathomimetic drugs are used for treating MS, but these drugs generally have some adverse reactions and are not suitable for all people.

Infection in an AIDS Patient with Cryptococcal Meningitis.

Concurrent infections caused by multiple fungal pathogens in immunocompromised patients can pose diagnostic and treatment challenges.

Violent Video Game Exposure and Cyberbullying in Early Adolescents: A Latent Moderated Mediation Model.

Violent video game exposure (VVGE) is a significant predictor of adolescent cyberbullying perpetration. However, little is known about the mediating and moderated mechanisms between them. This study examined the mediating role of moral disengagement between VVGE and cyberbullying perpetration as well as the moderating role of callous-unemotional (CU) traits on those associations.

Clinical metagenomics-assisted diagnosis of relapsed HIV-associated cryptococcal meningitis.

To date, the identification of crypotococcal relapse remains clinically challenging as it often has similar manifestation with paradoxical immune reconstitution inflammatory syndrome. This study reports on the use of metagenomics assisted next generation sequencing to aid in diagnosing recurrent cryptococcal meningitis in an person living with HIV experiencing recurring symptoms, despite negative culture results for in the cerebrospinal fluid. Although fungal culture was negative, when reads from metagenomic and metatranscriptomic sequencing performed on the Day 308 cerebrospinal fluid sample were mapped onto the genome from the Day 4 isolate, 589 specific reads were identified.

Extraction Optimization and Antioxidant Activities of Ethanol Extract of the Brown Roll-Rim Mushroom Paxillus involutus (Agaricomycetes).

The Impact of the COVID-19 Pandemic on Respiratory Syncytial Virus Infection: A Narrative Review.

Respiratory syncytial virus (RSV) is one of the most common respiratory viruses. It not only affects young children but also the elderly and immunocompromised patients. After the emergence of SARS-CoV-2 and the corona virus disease 2019 (COVID-19) era, a dramatic reduction in RSV activity was found, which coincided with the implementation of public health and social measures (PHSMs).

Blood Culture Negative Endocarditis: A Review of Laboratory Diagnostic Approaches.

Infective endocarditis is a potentially fatal condition, and identifying the pathogen is crucial to optimizing antibiotic treatment. While a blood culture takes time and may yield negative results, it remains the gold standard for diagnosis, blood culture-negative endocarditis, which accounts for up to 20% of infective endocarditis cases, poses a clinical challenge with increasing mortality. To better understand the etiology of blood culture-negative infective endocarditis, we reviewed non-culture-based strategies and compared the results.
