Background: Current literature indicates that safety measures, including lockdowns during the COVID-19 pandemic, severely disrupted our lifestyle, marked by increased screen time. The increased screen time is mostly associated with exacerbated physical and mental wellbeing. However, the studies that examine the relationship between specific types of screen time and COVID-19-related anxiety among youth are limited.
Methods: We examined the usage of passive watching, social media, video games, and educational screen time and COVID-19-related anxiety at the 5-time points (Early-Spring 2021, Late-Spring 2021, Fall 2021, Winter 2022, and Spring 2022) among youth in Southern Ontario, Canada ( = 117, mean age = 16.82, male = 22%, non-White = 21%) and investigated the role of 4 types of screen time in COVID-19 related anxiety. COVID-related anxiety was measured using the Coronavirus Anxiety Scale (CAS). Descriptive statistics examined the binary relationships between demographic factors, screen time, and COVID-related anxiety. Also, partially adjusted and fully adjusted binary logistic regression analyses were conducted to examine the association between the types of screen time and COVID-19-related anxiety.
Results: During the late Spring of 2021, when the provincial safety restrictions were most stringent, screen time was the highest among the 5 data collection time points. Further, adolescents experienced the highest COVID-19-related anxiety during this period. On the other hand, young adults experienced the highest COVID-19-related anxiety during Spring 2022. In a partially adjusted model (accounting for other types of screen time), engaging in 1-5 h per day on social media increased the likelihood of experiencing COVID-19-related anxiety compared to those who spend less than 1 h per day (OR = 3.50, 95%CI = 1.14-10.72, < 0.05). Other types of screen time was not significantly associated with COVID-19-related anxiety. In a fully adjusted model (accounting for age, sex and ethnicity besides four types on screen time), 1-5 h per day of social media remained significantly associated with COVID-19-related anxiety (OR = 4.08, 95%CI = 1.22-13.62, < 0.05).
Conclusion: Our findings suggest that COVID-19-related anxiety is associated with youth engagement in social media during the COVID-19 pandemic. Clinicians, parents, and educators should work collaboratively to provide developmentally appropriate approaches to reduce the negative social media impact on COVID-19-related anxiety and promote/foster resiliency in our community during the recovery period.

Background: Identifying strategies to engage with potential participants is critical for efficient enrollment in Alzheimer's Disease (AD) trials. Previous studies link faster speed of first contact with successful phone interview completion for Major Depressive Disorder (MDD) participants. This has not been examined in AD participants.

View Article and Find Full Text PDFBackground: Genetic studies have established that loss of function SORL1 gene variants are associated with Alzheimer's disease (AD). SORL1 encodes an endosomal trafficking receptor, SORLA, which regulates endosomal protein recycling through its interaction with the retromer core complex (consisting of VPS26, VPS35 and VPS29). Deficits in the levels and function of the SORLA-retromer complex are thought to underlie AD.

Most familial early-onset AD mutations in the APP, PSEN1/2 genes increase the ratio of Abeta42:Abeta40, which drives beta-amyloid accumulation in the brain. In 2001, the late Steve Wagner, Maria Kounnas, and I directed an agnostic high-throughput screen for compounds that would reverse the Abeta42:Abeta40, ratio, and discovered the first non-NSAID (second generation) gamma secretase modulators (GSM) at TorreyPines Therapeutics.

Background And Aim: As a classical formula to invigorate blood circulation, Huoxue Tongluo Qiwei Decoction (HTQD) can effectively treat hypertensive erectile dysfunction (ED), but its exact mechanism of action is not yet clear. The goal of this research was to explore the potential mechanism of HTQD in improving hypertensive erectile dysfunction in rats through transcriptomics, network pharmacology, and associated animal experimentations.
Methods: The HTQD chemical constituents were screened using high-performance liquid chromatography- tandem mass spectrometry (HPLC-MS/MS).
