Video gaming and sexual violence: rethinking forensic nursing in a digital age

Identification and validation of new fatty acid metabolism-related mechanisms and biomarkers for erectile dysfunction

Background

Erectile dysfunction (ED) is a common condition affecting middle-aged and elderly men.

Aim

The study sought to investigate differentially expressed fatty acid metabolism-related genes and the molecular mechanisms of ED.

Methods

The expression profiles of GSE2457 and GSE31247 were downloaded from the Gene Expression Omnibus database and merged. Differentially expressed genes (DEGs) between ED and normal samples were obtained using the R package limma. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses of DEGs were conducted using the R package clusterProfiler. Fatty acid metabolism-related DEGs (FAMDEGs) were further identified and analyzed. Machine learning algorithms, including Lasso (least absolute shrinkage and selection operator), support vector machine, and random forest algorithms, were utilized to identify hub FAMDEGs with the ability to predict ED occurrence. Coexpression analysis and gene set enrichment analysis of hub FAMDEGs were performed.

Outcome

Fatty acid metabolism-related functions (such as fatty acid metabolism and degradation) may play a vital role in ED.

Results

In total, 5 hub FAMDEGs (Aldh2, Eci2, Acat1, Acadl, and Hadha) were identified and found to be differentially expressed between ED and normal samples. Gene set enrichment analysis identified key pathways associated with these genes. The area under the curve values of the 5 hub FAMDEGs for predicting ED occurrence were all >0.8.

Clinical Translation

Our results suggest that these 5 key FAMDEGs may serve as biomarkers for the diagnosis and treatment of ED.

Strengths and Limitations

The strengths of our study include the use of multiple datasets and machine learning algorithms to identify key FAMDEGs. However, limitations include the lack of validation in animal models and human tissues, as well as research on the mechanisms of these FAMDEGs.

Conclusion

Five hub FAMDEGs were identified as potential biomarkers for ED progression. Our work may prove that fatty acid metabolism-related genes are worth further investigation in ED.

Sexual Violence in Virtual Reality: A Scoping Review

BACKGROUND

One in four Americans report experiencing harassment online via social media and interactive gaming, which includes physical threats, stalking, sexual harassment, and sustained harassment.

OBJECTIVE

The aim of this study was to gain understanding of the state of the science surrounding young adults and sexual violence/harassment harms in virtual reality (VR) as well as possible uses of VR to heal and intervene.

METHODS

A scoping review was conducted in early 2023 using the Ovid Synthesis Clinical Evidence Manager and the MEDLINE database. Forty-seven articles met inclusion criteria.

RESULTS

Our review found a growing body of evidence exploring incidents, effects, possible predictors, and initial strategies to prevent sexual violence in VR and to use the modality to positively intervene. Limited research addresses the effects of harms incurred in VR on (re)traumatization of survivors as well as the development and testing of VR tools used to educate, deliver bystander interventions, transform biases and perceptions via embodiment, and promote healing among survivors.

CONCLUSION

Research addressing sexual violence in VR is needed and should build on the existing peripheral science on gaming and social media environments. Forensic nursing is well positioned to advance strategies of health and safety in VR, just as in the physical world. Incorporating forensic nursing avatars in VR and deploying diverse resources targeted for college-age young adults to prevent harms in VR should be explored safely and ethically. Forensic nurses are also positioned to assess for VR-related harms among patients and to work with private and government sectors to influence regulations and policies.

Impact of COVID-19 on adolescent sexual life and attitudes: have we considered all the possible secondary effects of the pandemic?

A significant increase in pornography use has been reported in the adolescent population worldwide over the past few years, with intensification of the phenomenon during the COVID-19 pandemic. The aim of the present review is to provide data on the frequency of pornography consumption among adolescents during the pandemic and raise awareness about its potential impact on personal beliefs and sexual attitudes in the long term. A comprehensive literature review was performed in two scientific databases using the crossmatch of the terms "pornography", "adolescents" and "COVID-19". A significant increase in pornography consumption in adolescents was documented during the COVID-19 pandemic as a result of social detachment. Fulfilment of sexual desires in the context of social distancing, alleviation of COVID-19-related boredom and psychological strain, and coping with negative emotions are some of the reported reasons for increased pornography use during the pandemic. However, concerns have been raised in the literature regarding potentially negative effects of excessive pornography use from an early age, including the development of pornography addiction, sexual dissatisfaction and aggressive sexual attitudes reinforced by gender preoccupations and sexual inequality beliefs.

CONCLUSION

The extent to which increased pornography consumption from an early age during the COVID-19 pandemic may have affected adolescents' mental well-being, personality construction and sexual behaviour is yet to be seen. Vigilance from the society as a whole is required so that potential negative adverse effects of adolescent pornography use and potential social implications are recognized early and managed. Further research is needed so that the full impact of the COVID-19-related pornography use in the adolescent population is revealed.

WHAT IS KNOWN

•A significant increase in pornography consumption has been documented in the adolescent population worldwide over the past decades due to its quick, affordable and easy access from electronic devices and the possibility of anonymous and private participation. •During the COVID-19 pandemic, this phenomenon was intensified as a coping mechanism to social isolation and increased psychosocial strain.

WHAT IS NEW

•Concerns have been raised regarding the risk of pornography addiction in adolescents during the COVID-19 pandemic, making the post-pandemic adaptation challenging. •Awareness is raised in parents, health care providers and policy makers about the potential negative impacts of pornography consumption from an early, vulnerable age, such as sexual dissatisfaction and development of aggressive sexual attitudes and sex inequality beliefs.
