Increased aggression due to gaming addiction is a widespread and highly publicized problem. The underlying processes by which verbal aggression, a more harmful and persistent subcategory of aggression, is affected by gaming addiction may differ from other types of aggression. In this study, data came from 252 randomly recruited current university students (50.79% male, mean age 19.60 years, SD: 1.44 years, range 17 to 29 years). Participants reported gaming addiction and different types of aggression through questionnaires. In addition, two important explanatory processes, inhibitory control, and risk preference, were measured through behavioral experiments. A Bayesian hierarchical drift-diffusion model was employed to interpret the data from the risk preference task. In contrast to previous work, the study found that inhibitory control did not significantly correlate with either gaming addiction or any form of aggression However, the drift rate, a measure of decision-making inclination under risk, partially mediates the relationship between gaming addiction and verbal aggression (but not other forms of aggression). The findings illuminate risk preference under adverse conditions as a key predictor of verbal aggression, offering avenues for early intervention and suggesting game design modifications to mitigate verbal aggression by adjusting reward mechanisms.

Oral health remains one of the most taken for granted parts of human body health, even though poor oral health has now been linked to various diseases, such as cancers, diabetes, autoimmune complications, neurological disorders, and cardiovascular disease, just to name a few. As we review in this paper, substance use or abuse, including alcohol, smoking, recreational drugs, and pharmaceutical drugs can have significant implications on oral health, which in turn can lead to more systemic diseases. In this paper, we show that oral microbiome dysbiosis and inflammatory cytokine pathways are two of the most significant mechanisms contributing to oral health complications from substance use. When substance use decreases beneficial oral species and increases periodontopathogenic strains, a subsequent cascade of oncogenic and inflammatory cytokines is triggered. In this review, we explore these mechanisms and others to determine the consequences of substance use on oral health. The findings are of significance clinically and in research fields as the substance-use-induced deterioration of oral health significantly reduces quality of life and daily functions. Overall, the studies in this review may provide valuable information for future personalized medicine and safer alternatives to legal and pharmaceutical substances. Furthermore, they can lead towards better rehabilitation or preventative initiatives and policies, as it is critical for healthcare and addiction aid specialists to have proper tools at their disposal.

Understanding the socioecological contexts of gay men living with HIV is critical to addressing the environmental conditions that influence their lifetime experiences of housing insecurity and homelessness. In line with the strategies of the US Center for Disease Control and Prevention to end the HIV epidemic, it is of utmost importance to recognize how the allocation of available resources impacts health inequities affecting gay men living with HIV who experience housing insecurity and homelessness. Drawing from the World Health Organization’s social determinants of health (SDoH) framework, we used an exploratory, community-based research (CBR) approach to examine the lifetime experiences and important sources of support of gay men living with HIV at midlife who have experienced housing insecurity in Southern Nevada. Thematic analysis of our semi-structured interviews with 12 gay men living with HIV at midlife revealed three overarching themes: (1) challenges to obtaining housing and related support, (2) informal support from friends, and (3) formal support from community-based sources employing diverse support strategies. In this article, we discuss the different sub-themes we identified under these overarching themes and the implications of our findings from an SDoH perspective. We conclude with a discussion on the dire need to (1) highlight the considerable value of both informal and formal sources of support for the housing insecure, and (2) generate recommendations for interventions to address housing insecurity and homelessness with greater consideration for the impacts of SDoH in the work dedicated to helping gay men living with HIV at midlife overcome housing insecurity as they age.

Background: Depression is a serious and debilitating condition with a rising prevalence. Anhedonia, a core symptom of depression, is notably significant and the second most weighted factor among the non-somatic concerns of depression, following depressed mood. The interaction between technology use, mood, emotions, depression, and anhedonia is a critical area of investigation. Aim: This study aims to develop a comprehensive Systematic Review Protocol to examine the emotional effects of Internet-related behavior in young people. Methods: A systematic review protocol was developed following PRISMA guidelines for systematic reviews. The research question was formulated according to the PICOS framework. The search was conducted using PubMed/Medline, Cochrane Library, Embase, Scopus, and PsycInfo, supplemented by gray literature sources via Google Scholar. The methodological quality and risk of bias was assessed using the Critical Appraisal Skills Programme (CASP) framework. This systematic review protocol was registered on the Open Science Framework with the registration DOI: 10.17605/OSF.IO/SHNJU. Conclusions: The findings of this systematic review are expected to provide new evidence on the correlations between depression, Internet addiction, and anhedonia, contributing to the development of targeted intervention strategies and improving the understanding of young peoples’ emotional well-being.

Substance use self-stigma is a barrier to treatment and can negatively impact individuals’ well-being and treatment engagement. Given the mixed findings in previous research and the limited specific investigation into the concept of self-stigma within the context of opioid misuse, examining factors associated with self-stigma in the context of opioid use disorder (OUD) is warranted. The current study examines the influence of individual-level factors (race, sex, urban/rural status, support group attendance) on self-stigma and willingness to disclose opioid use. Data for this study were from a larger study of OUD-related stigma among adults in Pennsylvania, U.S. The current study included participants who indicated a personal past or current history with OUD were included (n = 84). Exploratory factor analysis and multiple indicators, multiple causes (MIMIC) model were used to explore the associations between demographic factors (i.e., sex, age, race/ethnicity, urban/rural status), attendance at mutual support groups, and self-stigma factors. Results indicated that sex and attendance at mutual support groups significantly predicted levels of self-stigma. Women and individuals with no previous experience attending mutual support groups endorsed lower levels of self-stigma. Additionally, attendance at mutual support groups predicted willingness to self-disclose past and present opioid use. Individuals who reported no history of attending mutual support groups demonstrated less willingness to disclose past and present OUD use compared to participants who were support group attendees. The current research findings enhance the understanding of OUD-related self-stigma by examining its relationship with individual-level factors, disclosure, and attendance to mutual support groups. The results offer insights into the influence of sex and support group attendance on self-stigma and disclosure. These findings have significant clinical implications for developing future interventions and promoting health policy changes. Full article

Objectives: To analyse the influence of the COVID-19 pandemic on the development of anxiety in nursing students and the factors involved. Design: A systematic review and meta-analysis. Data source: PubMed, CINAHL, Scopus and Web of Science. Background: Nursing students are at an increased risk of developing mental overload, due to the presence of many sources of stress during their academic training. Therefore, the COVID-19 pandemic has had an impact on the mental health of the general population, especially on healthcare workers and consequently on students undertaking placements in healthcare settings. Methods: A systematic review was conducted using PubMed, CINAHL, Scopus and Web of Science databases. A total of 24 articles were included in the review, and 20 articles were selected for the meta-analysis. Results: We found that the anxiety scores of nursing students during the COVID-19 pandemic were slightly higher (50%) than before the pandemic. The most influential risk factors for developing anxiety were academics, age, gender, having children, living in urban areas or with family, having an addiction to social networks, and having a fear of becoming infected with COVID-19. Resilience, spiritual support and feelings of happiness protected students against the risk of developing high levels of anxiety. Conclusions: The COVID-19 pandemic has led to increased levels of anxiety in nursing students. Thirty-five percent of the meta-analytically analysed sample had elevated levels of anxiety.

Many drastic actions are taken by cocaine users for the sake of experiencing high levels of dopamine, which depends on iron for its synthesis. Dopamine depletion and iron deficiency are also involved in the symptoms of restless leg syndrome (RLS). The intersecting biochemical pathways of cocaine use, iron deficiency, and RLS have not been adequately investigated. This case report reveals the successful treatment of a patient experiencing these conditions. A 63-year-old male with a history of cocaine use disorder, insomnia, and RLS sought emergency care for suicidality. Upon admission, he was also found to be iron deficient. He revealed that his RLS worsened when he attempted to abstain from cocaine. He also used alcohol to sustain the effects of cocaine when the cost of cocaine was too high. During hospitalization, his mood, cravings, and RLS were resolved with adjunctive iron supplementation, as well as treatment with 300 mg of Wellbutrin (bupropion hydroxychloride). If iron deficiency is present, the replenishment of the adequate dopaminergic receptor density and function via supplementation may play an essential role in the prevention of cocaine use and the cessation of cocaine withdrawal symptoms. Further research is warranted to validate these findings and to investigate the implications of iron supplementation in addiction medicine. Full article

Several scientific studies have highlighted the negative impact of new technologies (NTs) on children’s psychological development, both in terms of emotional and cognitive development. NTs, such as smartphones, tablets, and video games, have a significant impact on children’s development, both in terms of social relationships and cognitive functions. This study aims to identify and explore the cultural models that shape children’s exposure to new technologies in early childhood. This study involved 48 subjects between parents and infant educators. Unstructured interviews were conducted. Emotional Text Analysis was applied. The findings reveal the existence of three cultural repertoires (clusters): Connected but isolated (45.2), Technology education (30%), and Mistrust (24.8%). Their placement in the factorial space explains how the negative effects on children’s psychological development are determined. Technology education seems to be a protective factor for the cognitive and affective development of children. These findings are discussed, comparing them with Musk’s recent experiment and the rapid loss of social ties due to the lack of an educational plan. Full article

In 2017, Loscalzo and Giannini introduced the new potential clinical condition of studyholism (or obsession toward study) and a comprehensive model including its possible antecedents and outcomes. Then, emphasizing the value of avoiding an aprioristic (addiction) framework in analyzing problematic overstudying, they suggested conducting research on this new construct to unveil its internalizing and/or externalizing nature while also avoiding the over-pathologizing of a common behavior such as studying. Seven years after the first publication about studyholism, growing evidence concerning its antecedents suggested that studyholism might be defined as an OCD-related disorder (or, more generally, as an internalizing disorder). Moreover, the research about its outcomes highlighted that it is a problem behavior deserving attention as it is associated with academic, psychological, physical, and social downsides. Therefore, this paper aims to review the scientific literature published concerning studyholism to illuminate if it might be conceptualized as an OCD-related disorder based on its symptomatology, antecedents, and impact on individuals’ academic, physical, and psychological functioning. Given that it is a new construct, it is of critical value to systematize the findings gathered until now as it can help scholars interested in students’ well-being to have a clear understanding concerning the importance of screening studyholism since childhood, as this will help favor academic success and well-being and reduce the risk for school dropout. Finally, this paper presents an agenda for future research on studyholism, and it highlights the importance of further analyzing problematic overstudying using different theoretical perspectives (such as the behavioral addiction conceptualization) to unveil its real nature.

Cognitive impairment associated with schizophrenia (CIAS) represents one of the core features of the disorder and has a significant impact on functional and rehabilitation outcomes of people living with schizophrenia spectrum disorders (SSD). The aim of this critical review is to highlight the most recent evidence on effective treatments available for CIAS, to discuss the current challenges in this field, and to present future perspectives that may help to overcome them. Concerning psychopharmacological approaches, among the most indicated strategies for the management and prevention of CIAS is to favor second-generation antipsychotic medications and avoid long-term and high-dose treatments with anticholinergic medications and benzodiazepines. Moreover, non-pharmacological approaches such as cognitive remediation and physical exercise-based programs represent evidence-based interventions in the treatment of CIAS that have shown reliable evidence of effectiveness on both cognitive and functional outcomes. These treatments, however, are still delivered to people accessing mental health services with a diagnosis of CIAS in an uneven manner, even in high-income countries. Academic and clinical partnership and collaboration, as well as advocacy from service users, families, carers, and stakeholders’ organizations could help to reduce the bench to bedside gap in the treatment of CIAS. Future perspectives include the development of novel pharmacological agents that could be effective in the treatment of CIAS, the implementation of novel technologies such as telemedicine and virtual reality in the delivery of evidence-based interventions to improve accessibility and engagement, and further research in the field of non-invasive brain stimulation.

The severity and invasiveness of clinical outcomes from organic responses to trauma are influenced by individual, surgical, and anesthetic factors. A stress response elicits neuroendocrine and immune reactions that may lead to multi-organ dysfunction. The degree of neuroinflammatory reflex activation from trauma can increase pro-inflammatory cytokine production, leading to endothelial dysfunction, glycocalyx damage, neutrophil activation, and multisystem tissue destruction. A shift in patient treatment towards a neuroinflammatory perspective has prompted a new evaluation protocol for surgical patients, required to understand surgical pathogenesis and its link to chosen anesthetic–surgical methods. The goal of this study is to summarize and disseminate the present knowledge about the mechanisms involved in immune and neuroendocrine responses, focusing on video laparoscopic surgeries. This article outlines various measures cited in the literature aimed at reducing the burden of surgical trauma. It reviews anesthetic drugs, anesthetic techniques, and intensive care procedures that are known to have immunomodulatory effects. The results show a preference for more sensitive inflammatory mediators to tissue trauma serving as care tools, indicators for prognosis, and therapeutic outcomes. Full article

Background: The COVID-19 outbreak has profoundly affected the psychological well-being of university students globally. Previous studies have found a positive longitudinal link between fear of COVID-19 (FoC-19) and internet addiction. However, there is a notable gap in the literature regarding COVID-19-specific predictors and underlying mechanisms of internet gaming addiction (IGA). Methods: Integrating the compensatory internet use theory and social role theory as frameworks, a three-wave longitudinal approach was used in this study to test the hypothesized model. Data spanning a duration of one year were gathered from undergraduate students in China. From 2021 to 2022, we conducted online self-report surveys in the midst of the COVID-19 pandemic to obtain participants’ levels of FoC-19, loneliness, depressive symptoms, and IGA. Results: FoC-19 showed a longitudinal positive relationship with IGA. The longitudinal link between FoC-19 and IGA was mediated by loneliness and depression. Gender moderated the direct effect of FoC-19 on IGA, with this effect being significant only among male students and not among their female counterparts. Conclusion: These findings advance our comprehension of the mechanisms and gender differences underlying the link between FoC-19 and IGA, and provide a novel perspective for interventions to reduce IGA.

Cognitive impairment is a core feature of schizophrenia spectrum disorders (SSD). Violent and aggressive behavior represents a complex issue in psychiatry, and people with SSD have been shown to be at risk of being both victims and perpetrators of violence. In this review, the complex relationship between cognitive impairment and violent behavior is explored, also considering the usefulness of treating cognitive impairment to improve violence-related outcomes. Several studies report that cognitive impairment is linked to violent behavior, but significant differences between domains and conflicting results are also present, leaving the identification of specific cognitive profiles predicting violent behavior in SSD as an important aim for future research. Evidence regarding the effectiveness of treating cognitive impairment to improve violent behavior, while heterogeneous, provides more consistent results: cognition-targeting interventions appear to provide significant benefits also in the prevention of aggression in people living with SSD, and preliminary evidence shows cognition-focused interventions targeting violent behavior improve both cognition- and violence-related outcomes. Implementing these interventions in clinical practice could be of great usefulness, particularly in forensic contexts. Physical exercise, which improves cognitive performance and psychosocial functioning in SSD, appears to reduce violent behavior in healthy individuals, but requires further studies in clinical samples.

Corticotropin-releasing factor (CRF) is a key neuropeptide hormone that is secreted from the hypothalamus. It is the master hormone of the HPA axis, which orchestrates the physiological and behavioral responses to stress. Many disorders, including anxiety, depression, addiction relapse, and others, are related to over-activation of this system. Thus, new molecules that may interfere with CRF receptor binding may be of value to treat neuropsychiatric stress-related disorders. Also, CRF₁R antagonists have recently emerged as potential treatment options for congenital adrenal hyperplasia. Previously, several series of CRF₁ receptor antagonists were developed by our group. In continuation of our efforts in this direction, herein we report the synthesis and biological evaluation of a new series of CRF₁R antagonists. Representative compounds were evaluated for their binding affinities compared to antalarmin. Four compounds (2, 5, 20, and 21) showed log IC₅₀ values of −8.22, −7.95, −8.04, and −7.88, respectively, compared to −7.78 for antalarmin. This result indicates that these four compounds are superior to antalarmin by 2.5, 1.4, 1.7, and 1.25 times, respectively. It is worth mentioning that compound 2, in terms of IC₅₀, is among the best CRF₁R antagonists ever developed in the last 40 years. The in silico physicochemical properties of the lead compounds showed good drug-like properties. Thus, further research in this direction may lead to better and safer CRF receptor antagonists that may have clinical applications, particularly for stress-related disorders and the treatment of congenital adrenal hyperplasia.

Chronic pain is frequently associated with neuropathy, inflammation, or the malfunctioning of nerves. Chronic pain is associated with a significant burden of morbidity due to opioid use, associated with addiction and tolerance, and disability. MicroRNAs (miRs) are emerging therapeutic targets to treat chronic pain through the regulation of genes associated with inflammation, neuronal excitability, survival, or de-differentiation. In this review, we discuss the possible involvement of miRs in pain-related molecular pathways. miRs are known to regulate high-conviction pain genes, supporting their potential as therapeutic targets.
