Retinal Vessel Diameter and Symptoms of Depression and Anxiety in Young Adults

Previous studies suggest an association between depression and anxiety in childhood and adolescence and increased risk for cardiovascular disease later in life. The aim of the present study was to test whether depression and anxiety symptoms in young adulthood were associated with retinal vessel diameter, a subclinical marker of cardiovascular disease. We further tested whether associations for depression were similar to associations for anxiety. Participants completed questionnaires about their depression and anxiety symptoms and underwent retinal imaging. Retinal vessel diameter was assessed using computer software. Results showed no association between depression or anxiety symptoms and retinal vessel diameter, suggesting that retinal vessel diameter may not signal subclinical cardiovascular risk in young adults with symptoms of depression and anxiety.

Using Logistic Regression to Predict Stock Trends Based on Bag-of-Words Representations of News Article Headlines

Description

We attempted to apply a novel approach to stock market predictions. The Logistic Regression machine learning algorithm (Joseph Berkson) was applied to analyze news article headlines as represented by a bag-of-words (tri-gram and single-gram) representation in an attempt to predict the trends of stock prices based on the Dow Jones…

We attempted to apply a novel approach to stock market predictions. The Logistic Regression machine learning algorithm (Joseph Berkson) was applied to analyze news article headlines as represented by a bag-of-words (tri-gram and single-gram) representation in an attempt to predict the trends of stock prices based on the Dow Jones Industrial Average. The results showed that a tri-gram bag led to a 49% trend accuracy, a 1% increase when compared to the single-gram representation’s accuracy of 48%.

Brief, Non-Pharmacological, Interventions for Pediatric Anxiety: Meta-Analysis and Evidence Base Status

There is a need to reinvent evidence-based interventions (EBIs) for pediatric anxiety problems to better address the demands of real-word service delivery settings and achieve public health impact. The time- and resource-intensive nature of most EBIs for youth anxiety has frequently been noted as a barrier to the utilization of EBIs in community settings, leading to increased attention towards exploring the viability of briefer, more accessible protocols. Principally, this research reports between-group effect sizes from brief-interventions targeting pediatric anxiety and classifies each as well-established, probably efficacious, possibly efficacious, experimental, or questionable. brief interventions yielded an overall mean effect size of 0.19 on pediatric anxiety outcomes from pre to post. Effect sizes varied significantly by level of intervention: Pre to post-intervention effects were strongest for brief-treatments (0.35), followed by brief-targeted prevention (0.22), and weakest for brief-universal prevention (0.09). No participant or other intervention characteristic emerged as significant moderators of effect sizes. In terms of standard of evidence, one brief intervention is well-established, and five are probably efficacious, with most drawing on cognitive and behavioral change procedures and/or family systems models. At this juncture, the minimal intervention needed for clinical change in pediatric anxiety points to in-vivo exposures for specific phobias (~3 hours), cognitive-behavioral therapy (CBT) with social skills training (~3 hours), and CBT based parent training (~6 hours, eight digital modules with clinician support). This research concludes with a discussion on limitations to available brief EBIs, practice guidelines, and future research needed to capitalize on the viability of briefer protocols in enhancing access to, and impact of, evidence-based care in the real-world.

The Association Between Acne and Social Appearance Anxiety and Other Correlates Among Undergraduates

The goal of the current study was to investigate the prevalence of SAA and body dissatisfaction among freshman undergraduate students between 18-20 years old suffering from self-reported acne. A total of 73 participants in an online survey were asked to complete the Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Body Parts Satisfaction Scale (BPSS), and Social Appearance Anxiety Scale (SAAS). No significant correlation was found between acne severity and SAAS scores, but a significant, positive correlation was found between acne severity and body dissatisfaction. Moreover, acne sufferers had higher mean scores for the BPSS than non-acne sufferers indicating higher body dissatisfaction, but there was no significant difference in the scores for the SAAS between acne sufferers and non-acne sufferers. There was also no significant difference in correlations between acne severity and SAAS scores or BPSS scores between men and women, however, women had much higher mean scores for SAAS than men. In addition, scores for the SAAS and BPSS were found to have a significant, positive correlation with both depression and anxiety across the entire sample. There is paucity of research on the psychosocial effects of acne, more specifically social appearance anxiety (SAA), so further research is needed to replicate and extend the findings of the current study using a larger sample size ranging in acne severity.

The field of veterinary medicine can be rewarding, but also very demanding. Research has shown that many practicing veterinarians struggle with mental illness, and the profession has one of the highest suicide rates in the United States. Research has also shown that many veterinary students struggle with mental illness. It is important to further research the mental health of veterinary students and how that can correlate with one's mental health as a practicing veterinarian. The purpose of this project is to summarize findings of the literature concerning the mental health of veterinary students and to present a new resource, the Wisdom Vet app, that can potentially support the well-being of veterinary students.

Social media has become a prominent part of people’s life worldwide. It allows for easy communication and connection between family, friends, and even complete strangers. It has provided for an increased global interconnectedness and allows people to form new relationships. Despite these positives, there are also negative effects of social media, including its danger to mental health. With increased social media use, it is possible to develop an addiction, similar to any substance addiction. People may also experience various mental health disorders, like depression and anxiety disorders. The purpose of this review was to identify a clear relationship between social media use and the development of anxiety disorders. Anxiety disorders is a general term, encompassing the different types, but the main types focused on in this review are generalized anxiety disorder and social anxiety. This review also incorporates information on age in order to clarify if certain age groups are more affected by social media use than others.
