Predictive factors and symptom severity spectrum in adult schizophrenia: Potential insights for improved management and adequate care.

Schizophrenia is one of the most disabling psychiatric disorders characterized by positive (hallucinations, delusions, formal thinking disorder) and negative symptoms (anhedonia, lack of speech and motivation). The present study aimed to identify the predictive factors of schizophrenia in adults, and potential differences in the environment of origin, sex, levels of occupational stress, intellectual level, marital status and age of onset of the disease depending on the severity of symptoms using analysis of data collected from 120 patients with a diagnosis of schizophrenia. The study was conducted at the 'Prof. Dr. Alexandru Obregia' Clinical Psychiatric Hospital in Bucharest and included adult patients hospitalized between March 2018 and January 2021 diagnosed with schizophrenia and evaluated by general clinical examination, psychiatric, neurological and psychological evaluation. Results revealed that robust predictors of mild and moderate symptoms were affective symptoms, heredo-collateral history of schizophrenia, late onset, the presence of positive and negative symptoms, substance abuse, stress and marital status, unmarried, lower IQ and mental deficiency. For moderate-severe and severe symptoms, predictors were affective symptoms, heredo-collateral history of schizophrenia and affective disorders, substance abuse, stress, borderline IQ and mild mental deficiency. The present results can be used for further development of psychopharmacological management of schizophrenia.

Public Perception Towards Drug Abuse in South Korea: The Effects of Overconfidence and Affirmation.

OBJECTIVE: The abuse of prescription drugs and over-the-counter medicines has been a major issue addressed as a serious public health problem worldwide. This study explored factors contributing to substance abuse in Korea by examining the status of substance abuse among Korean adults and evaluating their knowledge, attitudes, and intentions toward substance abuse. METHODS: Data were collected online from a sample of participants 19 years old or older from May 20 to June 1, 2020 (n=1,020). The survey consisted of questions on demographics, perceptions of drug risk, motives for drug use, and attitudes toward drug addiction treatment. Principal component and multiple logistic regression analyses were used to explore the factors contributing to the perception of drug abuse. RESULTS: In the multivariate regression analysis, overconfidence in handling drug usage, acceptance of addictive substances, and affirmation of public support for drug abuse were associated with opioid abuse (Nagelkerke R2=0.486), and additionally affirmation of legal cannabis usage and motivation to use diet pills were associated with diet pill abuse (Nagelkerke R2=0.569). CONCLUSION: The findings of this study suggest that the actual situation of substance abuse among Korean adults increases awareness of and attitudes toward drug use related to substance abuse.

Exploring sleep difficulties, alcohol, illicit drugs, and suicidal ideation among adolescents with a history of depression.

Sleep difficulties and misuse of drugs/alcohol have been associated with suicidal ideation in young people. Using cross-sectional representative surveys of adolescents in the United States, we conducted adjusted logistic regression modeling to assess the relationships between sleep difficulties, substance use, and suicidal ideation among adolescents with a history of depression (n = 38,418) between 2015 and 2020. Sleep difficulties were associated with thinking about (aOR=1.6,95%CI:1.3-1.9), planning (aOR=1.8,95%CI:1.2-2.6), or attempting (aOR=1.7,95%CI:1.2-2.5) suicide. In those reporting alcohol abuse/dependence, sleep difficulties were associated with attempting suicide (aOR=3.1,95%CI:1.2-8.5). In those reporting illicit drug abuse/dependence, sleep difficulties were associated with thinking about (aOR=2.1,95%CI:1.1-4.1) and attempting (aOR=2.2,95%CI:1.2-4.1) suicide.

Formative Assessment and Cluster Membership of Homeless Persons' Emergency Department Visits.

Background Evidence is limited on whether homeless individuals who visit emergency departments (EDs) share similar clinical characteristics as individuals from private households who, upon examination, require emergency health services beyond preventative healthcare. While the literature is rich with studies on homeless persons in the ED, a comprehensive assessment of similarities and differences with other social groups is lacking. Consequently, there is a gap in knowledge as it pertains to the appropriate approaches that will further support the development of targeted healthcare and emergency health services for the homeless person. Aim The goal is to provide a framework for targeted interventions that hospitals can develop based on behavioral, health, and social characteristics and, in the process, better meet the healthcare needs of homeless patients. Methods Data were collected from the records of 85,350 patients in the National Hospital Ambulatory Medical Care Survey (NHAMCS) database who visited the ED between the years of 2013 and 2016; each patient was classified as having either a private residence, living in a nursing home, or homeless (n = 83,446, n = 1,459, and n = 925, respectively). Results Cluster analysis of the data confirmed that individuals with multiple comorbidities, as well as substance abuse or dependency, regardless of residence type, were more likely to have recurrent ED visits within 72 hours. Nominal regression analyses revealed that cluster membership generated from ED data could predict patient residence and suggest that substance abuse and depression can predict 72-hour ED visit recurrence. Conclusion Cluster analyses have the potential to reveal social health and group characteristics and can support targeted solutions respective to group individualities in the ED.

Midlife and Older Age Methamphetamine Poisoning Deaths in Hawai'i.

Unintentional and undetermined intent drug overdose fatality records from the State Unintentional Drug Overdose Reporting System (SUDORS) for Hawai'i from July 1, 2020, to December 31, 2021 revealed that 58.2% of decedents were aged 50-75. The main substance associated with cause of death for those aged 50-75 years was methamphetamine, followed by a combination of mixed drugs. Of those aged 50 and older, 25.5% died from cardiovascular or neurological complications which were likely to be associated with chronic, long-term methamphetamine use. Based on death investigator narrative reports, 76.5% of the older decedents had a history of substance abuse, suggesting possible long-term substance use starting at a young age. The trajectory of substance use over the life course is often influenced by life events and transitions, which can be stressors. Hawai'i kupuna (older adults) should be screened for substance use and dependence to ensure that there is treatment if needed, for the entirety of this use trajectory.Also, barriers to kupuna seeking treatment, such as stigma towards drug use should be addressed.

Effects of Substance Use on Condomless Anal Sex in a Large Sample of Adolescent Men Who Have Sex with Men: A Within and Between Relationship Design.

Substance use is a significant risk factor for HIV infection among adolescent men who have sex with men (AMSM). Substance use may reduce the use of HIV prevention measures or increase the likelihood of engaging in activities with a higher risk of HIV transmission, but there is a lack of studies dedicated to analyzing these mechanisms in adolescents and young MSM. This study aimed to explore the impact of substance use on condomless anal sex (CAS) in a large, racially diverse sample of AMSM. Additionally, we investigated how an individual's general level of substance use moderated the association between substance use before sex and CAS at the partnership level. Baseline data for an HIV prevention intervention were collected through online surveys from April 2018 to June 2020. The sample consisted of 1624 AMSM (M age, 16.69 years) who reported at least one sexual partner in the previous 3 months. Participants provided information about their three most recent sexual partners, including their relationship to the partner, PrEP use, frequency of alcohol, marijuana, and non-prescription drug use before sex, and the number of CAS acts. Participants also completed measures of their substance use frequency. Multilevel modeling in Mplus was used for data analysis, accounting for sexual partnerships nested within participants. All models controlled for PrEP use and relationship status. Results revealed a significant positive association between the frequency of non-prescription drug use before sex and CAS at the partnership level. This indicates that higher non-prescription drug use frequency before sex was associated with a greater number of CAS acts with partners. Moreover, the cross-level interaction between alcohol frequency and non-prescription drug use before sex was statistically significant. Specifically, for participants with high alcohol frequency scores, there was a significant positive association between non-prescription drug use before sex and CAS at the partnership level. AMSM with higher average alcohol consumption were more likely to engage in CAS when using non-prescription drugs prior to sex with a partner, compared to those with lower alcohol consumption. This study's use of multilevel data analysis contributes innovatively to the field by shedding light on how substance use operates within sexual relationships and different partnership dynamics. Tailored interventions targeting substance use should be developed to reduce HIV risk among AMSM.

Using Interactive Television Instruction (ITV) to Reduce the Propensity to Engage in Substance Abuse and Drug Trafficking Among Vulnerable Adolescents in Nigeria.

This study examined the impact of ITV intervention on reduction in the propensity to abuse substances and engage in drug trafficking. The researcher conducted this study using an experiment of 517 vulnerable adolescents aged 10-19 years. The participants were randomly assigned to control (n = 258) and treatment (n = 259) groups. The researchers found a significant main effect of treatment conditions on reduction in the propensity to engage in substance abuse and drug trafficking among vulnerable adolescents. That is, before the intervention, there was no significant statistical difference between the control and treatment groups on the propensity to engage in substance abuse and drug trafficking. However, vulnerable children who received the intervention reported a significant reduction in propensity after the intervention. The results highlight the usefulness of ITV as a behaviour change strategy for vulnerable children.

Health-Related Quality of Life and its Determinants among School-going Adolescents: A Cross-sectional Study.

Background: Adolescents experience rapid physical, cognitive, and psychosocial growth in their transition from childhood to adulthood, affecting health outcomes and well-being. Health-related quality of life (HRQoL) is a useful indicator of health outcomes, assessed in the current study along with associated determinants. Methods: A cross-sectional study was conducted among 634 randomly selected adolescents from 13 randomly selected schools in Gharwal division, Uttarakhand, India, from August 2019 to September 2020. The students studying in the 8th-11th standard and those providing assent and consent from their parents were included in the study. They were screened using the short version of the Physical Activity Readiness Questionnaire. Along with physical activity and fitness assessment, the Global School-based Student Health Survey questionnaire was administered. The transformed HRQoL domain scores were calculated using the WHOQOL-BREF questionnaire. A univariate and multivariable linear regression model was applied to identify the determinants of HRQoL using SPSS version 23. Results: The study included 324 (51.1%) boys and 310 (48.9%) girls. The mean age of the students was 14.4±1.4 years. The highest mean score was 72.3±21.0 for the social relationship domain and the lowest was 55.6±15.0 for the physical domain. The age, parents using any form of tobacco, a history of ever-use of alcohol and physical fitness were significantly associated with HRQoL domain scores. The non-dominant back stretch test was also significantly associated (Beta coefficient; SE, P-value) with physical (-4.1; 1.4, 0.002), psychosocial (-3.9; 1.5, 0.010) and environmental (-3.5; 1.4, 0.014) domain scores. Conclusion: All domains of HRQoL need to be improved and should address the psychological, social, and mental well-being of adolescents. Physical activity and fitness of students emerged as a strong modifiable predictor affecting almost all the domains of HRQoL, warranting its promotion in schools and the promotion of healthy behavior among parents and adolescents.

Substance Use Treatment for Indigenous Offenders: The Effects of Race on Drug Court Treatment Outcomes.

With drug offenders making up a large portion of cases in the criminal justice system, efforts to reduce recidivism among this population has been a sizable topic within research. Within this literature, drug courts continue to be shown to be an effective method of dealing with substance use offenders. The current study seeks to examine whether drug courts are similarly effective in treating White and Native American offenders. To do so, a quasi-experimental study with a matched comparison group is used to compare the 1- and 2-year recidivism rates of White and Native drug court participants. Results indicate that there are significant demographic differences between the two groups which lead to higher recidivism rates among Native American participants. However, once demographic and other control variables are accounted for, recidivism rates are not significantly different. Further implications of these findings are discussed in the conclusion.

Public Perceptions of Treating Opioid Use Disorder With Deep Brain Stimulation: Comment Analysis Study.

BACKGROUND: The number of opioid-related deaths in the United States has more than tripled over the past 7 years, with a steep increase beginning at the same time as the COVID-19 pandemic. There is an urgent need for novel treatment options that can help alleviate the individual and social effects of refractory opioid use disorder (OUD). Deep brain stimulation (DBS), an intervention that involves implanting electrodes in the brain to deliver electrical impulses, is one potential treatment. Currently in clinical trials for many psychiatric conditions, including OUD, DBS's use for psychiatric indications is not without controversy. Several studies have examined ethical issues raised by using DBS to counter treatment-resistant depression, obsessive-compulsive disorder, and eating disorders. In contrast, there has been limited literature regarding the use of DBS for OUD. OBJECTIVE: This study aims to gain empirical neuroethical insights into public perceptions regarding the use of DBS for OUD, specifically via the analysis of web-based comments on news media stories about the topic. METHODS: Qualitative thematic content analysis was performed on 2 Washington Post newspaper stories that described a case of DBS being used to treat OUD. A total of 292 comments were included in the analysis, 146 comments from each story, to identify predominant themes raised by commenters. RESULTS: Predominant themes raised by commenters across the 2 samples included the hopes and expectations with treatment outcomes, whether addiction is a mental health disorder, and issues related to resource allocation. Controversial comments regarding DBS as a treatment method for OUD seemingly decreased when comparing the first printed newspaper story to the second. In comparison, the number of comments relating to therapeutic need increased over time. CONCLUSIONS: The general public's perspectives on DBS as a treatment method for OUD elucidated themes via this qualitative thematic content analysis that include overarching sociopolitical issues, positions on the use of technology, and technological and scientific issues. A better understanding of the public perceptions around the use of DBS for OUD can help address misinformation and misperceptions about the use of DBS for OUD, and identify similarities and differences regarding ethical concerns when DBS is used specifically for OUD compared to other psychiatric disorders.

Analysis of toxicological findings related to immunofluorescence investigations.

Background: The subject of this article is the role of forensic toxicology in post-mortem examinations using immunofluorescence methods, its implications and its role in providing conclusive evidence for both criminal and civil proceedings. The aim of the study is to verify the correlation between the mode of death and the ingestion of exogenous substances and, if positive, to identify the category of substances ingested and assess their role in the cause of death. Materials and methods: A laboratory study was carried out, consisting of several phases: pre-analytical phase; analytical phase; post-analytical phase. The variables analyzed were sex, cause of death, age. Abused substances tested: amphetamines, methamphetamines, barbiturates, benzodiazepines, cocaine, methadone, opiates, tricyclic antidepressants, delta-9-tetrahydrocannabinol (cannabis), alcohol. Conclusions: Retrospective analysis was performed on a total sample of 55 cases. The most relevant data emerged: cocaine with an incidence of 7.3% (4 cases out of 55), amphetamines with 5.4% (3 cases in total). The results of the screening tests were then subjected to confirmatory tests. There is an association between the use of certain exogenous substances and an increased risk of certain causes of death, such as overdose, traffic accidents, cardiovascular deaths, etc. This paper has highlighted the possibility of using first level immunological tests, such as immunofluorescence, to provide preliminary answers to the judicial authority immediately after autopsy, and a quantitative deepening with further second level tests, such as gas chromatography, as a gold standard to determine the cause of death.

Acceptability, feasibility and fidelity of the culturally adapted version of Unplugged ("Yo Se Lo Que Quiero"), a substance use preventive program among adolescents in Chile: a pilot randomized controlled study.

INTRODUCTION: The consumption of alcohol, tobacco, and cannabis is a public health problem that impacts the cognitive, social, and emotional development of adolescents. Prevention strategies such as the "Unplugged" program are effective in delaying the progression of daily smoking and episodes of drunkenness among adolescents. "Yo Se Lo Que Quiero" (YSLQQ) corresponds to the adaptation of this program to the Chilean context. This study assesses the acceptability and feasibility of implementing this program to the local reality. MATERIAL AND METHODS: This was a cluster-randomized controlled pilot study conducted on six public schools. All consented students attending 6th, 7th, and 8th grades (n = 1,180) participated in the study. The schools were randomly assigned to one of two conditions in a 1:1 ratio: (1) the "YSLQQ" intervention group (n = 526), and (2) the Control group (n = 654). The program consisted of a 12-hour class-based curriculum based on a comprehensive social-influence approach delivered by a trained facilitator. The acceptability and feasibility were assessed in the intervention group at the end of the intervention using questionnaires answered by students and facilitators. The quality and fidelity of the program were evaluated during the implementation using self-ported surveys answered by the facilitators and the assessment of video-recorded sessions rated by external observers. Finally, a pre-test and a post-test survey assessing past and current substance use and risk and protective factors were conducted before and immediately after the program's implementation. RESULTS: A high proportion of students (49.6%) liked the sessions. 79.2% reported that the YSLQQ helped them learn about the dangers of substances, while 65.8% reported having more skills to avoid substance use in the future. Regarding students' satisfaction with YSLQQ, 62.9% reported being happy or very happy with the program. Facilitators reported implementing the intervention according to the manual in 73.9% of sessions. Regarding substance use, students who participated in the intervention groups reported a significant reduction in drunkenness in the last year and last 30-day prevalence and also a significant reduction in a lifetime and 30-day prevalence of cannabis use when compared with those students in the control group. CONCLUSIONS: Our results suggest that YSLQQ has adequate acceptability and feasibility to be implemented in the Chilean context, and there were promising results in reducing drunkenness and cannabis use. Future research should confirm these results in a larger RCT study. TRIAL REGISTRATION: The trial was registered in ClinicalTrials.gov, NCT04566627; registration date: 01/03/2019.

A Case Report of an Acute Severe Tachyarrhythmia Presentation With Underlying Cardiomyopathy in a Patient With Anabolic Androgenic Steroid and Thyroxine Misuse.

A description of an acute hospital presentation with severe tachyarrhythmia requiring multiple direct current cardioversions in a 45-year-old male bodybuilder with underlying cardiomyopathy possibly caused by long-term anabolic steroid abuse and more recent thyroxine misuse is described. A review of the literature regarding the above associations was also done. This case report further adds to the literature regarding the harmful effect of androgenic anabolic steroid misuse (with the added effect of thyroxine misuse in this case) on the heart.

Exploring the Nexus of Climate Change and Substance Abuse: A Scoping Review.

INTRODUCTION: The increase in average air temperature and multiple extreme weather events, such as heatwaves and droughts, pose significant health risks to humans. This scoping review aims to examine the current state of the existing literature concerning the potential relationship between substance abuse and climate change, along with the aspects it encompasses. MATERIAL AND METHODS: The review followed PRISMA guidelines for methodological rigor, aiming to identify studies on drug abuse. Searches were conducted across the primary databases using specific search strings. Quality assessment involved evaluating the research question's clarity, search strategy transparency, consistency in applying the inclusion/exclusion criteria, and reliability of data extraction. RESULTS: Most studies were conducted in the USA. They included observational and retrospective quantitative studies, as well as qualitative and prospective observational ones. Research examined the correlation between extreme weather and some substance abuse. All studies analyzed the adverse effects of climate change, especially heatwaves, on both physiological and pathological levels. CONCLUSIONS: The scoping review notes the scarcity of studies about the correlation between substance abuse and climate change, and emphasizes the threats faced by individuals with substance abuse and mental health disorders due to climate change.

COVID-related disruptions and adaptations to prison-based mental health and substance use services: a narrative review.

PURPOSE: Public health experts and advocates have long raised concerns about the pandemic preparedness of prison systems worldwide - an issue that became increasingly salient at the start of the COVID-19 pandemic. People in prison experience poorer health outcomes compared to the general population, making timely access to adequate health services in prison critical for their health and wellbeing. This study aims to identify the extent of the literature on initial changes in mental health and substance use services for people in prison during the COVID-19 pandemic, summarize and synthesize the findings and identify areas in need of further study. DESIGN/METHODOLOGY/APPROACH: The authors conducted a review of the academic literature published internationally in English between 2019 and December 1, 2020 to describe the disruptions and adaptations to mental health and substance use services in prisons during the onset of the COVID-19 pandemic. FINDINGS: The authors found that mental health and substance use services in prisons around the world were widely disrupted due to the COVID-19 pandemic - predominantly consisting of the complete suspension of services, discontinuation of transfers to off-site treatment sites and limitations on service capacity. Adaptations ranged from virtual service delivery and changes to treatment dispensation processes to information sessions on overdose prevention. ORIGINALITY/VALUE: To the best of the authors' knowledge, this is the first review to examine the nature and extent of the literature on delivery of mental health and substance use services in prisons during the COVID-19 pandemic.

The Impact of Medicaid Institutions for Mental Disease Exclusion Waivers on the Availability of Substance Abuse Treatment Services and the Varying Effect by Ownership Type.

Policy Points The adoption of Medicaid institutions for mental disease (IMD) exclusion waivers increases the likelihood of substance abuse treatment facilities offering mental health and substance abuse treatment for co-occurring disorders, especially in residential facilities. There are differential responses to IMD waivers based on facility ownership. For-profit substance abuse treatment facilities are responsive to the adoption of IMD substance use disorder waivers, whereas private not-for-profit and public entities are not. The response of for-profit facilities suggests that integration of substance abuse and mental health treatment for individuals in residential facilities may be cost-effective. CONTEXT: Access to integrated care for those with co-occurring mental health (MH) and substance use disorders (SUDs) has been limited because of an exclusion in Medicaid on paying for SUD care for those in institutions for mental disease (IMDs). Starting in 2015, the federal government encouraged states to pursue waivers of this exclusion, and by the end of 2020, 28 states had done so. It is unclear what impact these waivers have had on the availability of care for co-occurring disorders and the characteristics of any facilities that expanded care because of them. METHODS: Using data from the National Survey of Substance Abuse Treatment Services, we estimate a two-stage residual inclusion model including time- and state-fixed effects to examine the effect of state IMD SUD waivers on the percentage of facilities offering co-occurring MH and SUD treatment, overall and for residential facilities specifically. Separate analyses are conducted by facility ownership type. FINDINGS: Results show that the adoption of an IMD SUD waiver is associated with 1.068 greater odds of that state having facilities offering co-occurring MH and substance abuse (SA) treatment a year or more later. The adoption of a waiver increases the odds of a state's residential treatment facility offering co-occurring MH and SA treatment by 1.129 a year or more later. Additionally, the results suggest 1.163 higher odds of offering co-occurring MH/SA treatment in private for-profit SA facilities in states that adopt an IMD SUD waiver while suggesting no significant impact on offered services by private not-for-profit or public facilities. CONCLUSIONS: Our study findings suggest that Medicaid IMD waivers are at least somewhat effective at impacting the population targeted by the policy. Importantly, we find that there are differential responses to these IMD waivers based on facility ownership, providing new evidence for the literature on the role of ownership in the provision of health care.

Effect of a Smartphone App (S-Check) on Actual and Intended Help-Seeking and Motivation to Change Methamphetamine Use Among Adult Consumers of Methamphetamine in Australia: Randomized Waitlist-Controlled Trial.

BACKGROUND: Interventions are required that address delays in treatment-seeking and low treatment coverage among people consuming methamphetamine. OBJECTIVE: We aim to determine whether a self-administered smartphone-based intervention, the "S-Check app" can increase help-seeking and motivation to change methamphetamine use, and determine factors associated with app engagement. METHODS: This study is a randomized, 28-day waitlist-controlled trial. Consenting adults residing in Australia who reported using methamphetamine at least once in the last month were eligible to download the app for free from Android or iOS app stores. Those randomized to the intervention group had immediate access to the S-Check app, the control group was wait-listed for 28 days before gaining access, and then all had access until day 56. Actual help-seeking and intention to seek help were assessed by the modified Actual Help Seeking Questionnaire (mAHSQ), modified General Help Seeking Questionnaire, and motivation to change methamphetamine use by the modified readiness ruler. χ2 comparisons of the proportion of positive responses to the mAHSQ, modified General Help Seeking Questionnaire, and modified readiness ruler were conducted between the 2 groups. Logistic regression models compared the odds of actual help-seeking, intention to seek help, and motivation to change at day 28 between the 2 groups. Secondary outcomes were the most commonly accessed features of the app, methamphetamine use, feasibility and acceptability of the app, and associations between S-Check app engagement and participant demographic and methamphetamine use characteristics. RESULTS: In total, 560 participants downloaded the app; 259 (46.3%) completed eConsent and baseline; and 84 (32.4%) provided data on day 28. Participants in the immediate access group were more likely to seek professional help (mAHSQ) at day 28 than those in the control group (n=15, 45.5% vs n=12, 23.5%; χ21=4.42, P=.04). There was no significant difference in the odds of actual help-seeking, intention to seek help, or motivation to change methamphetamine use between the 2 groups on the primary logistic regression analyses, while in the ancillary analyses, the imputed data set showed a significant difference in the odds of seeking professional help between participants in the immediate access group compared to the waitlist control group (adjusted odds ratio 2.64, 95% CI 1.19-5.83, P=.02). For participants not seeking help at baseline, each minute in the app increased the likelihood of seeking professional help by day 28 by 8% (ratio 1.08, 95% CI 1.02-1.22, P=.04). Among the intervention group, a 10-minute increase in app engagement time was associated with a decrease in days of methamphetamine use by 0.4 days (regression coefficient [ß] -0.04, P=.02). CONCLUSIONS: The S-Check app is a feasible low-resource self-administered intervention for adults in Australia who consume methamphetamine. Study attrition was high and, while common in mobile health interventions, warrants larger studies of the S-Check app. TRIAL REGISTRATION: Australian New Zealand Clinical Trials Registry ACTRN12619000534189; https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=377288&isReview=true.

Investigating the Effect of Substance Desire and Child Abuse in Adolescent Suicide Attempt.

Background: This study aimed to investigate the impact of child abuse and substance desire on adolescent suicide. Methods: This cross-sectional analytical study was conducted on all adolescents aged 12 to 19 who attempted suicide in 2018 at Khorshid Hospital, Isfahan, Iran. A checklist of the patients' demographic information, toxicological data, and 2 standard questionnaires, including substance desire (family, personal, social) and child abuse questionnaire (emotional abuse, physical abuse, and neglect abuse), were collected. The data were analyzed using SPSS version 15. Comparisons between the 2 groups were performed using t tests, chi-square tests, regression analysis, and crude model analysis. Odds ratio (OR) and 95% confidence interval were calculated based on logistic regression. Findings: A total of 196 teenagers were included in the study, with a mean age of 16.48±1.6 years. Out of these, 155 individuals (79.1%) were female, resulting in a female-to-male ratio of 3.78. There was a significant relationship between gender and alcohol consumption in the personal aspect, as well as between the history of psychiatric diseases and alcohol consumption in the physical aspect (P<0.005). The previous history of suicide was the only variable that showed significance in all aspects of both the substance desire and child abuse questionnaires. History of neglect abuse (OR: 1.2, 95% CI [1.07-1.41]; P=0.009) was a predictive factor for suicide attempt. However, being male (OR: 0.12, 95% CI [0.039-0.37], P=0.000), having no psychiatric history (OR: 0.23, 95% CI [0.10-0.52], P<0.001) and not consuming alcohol (OR 0.33, 95% CI 0.15-0.71, P=0.005) were identified as protective factors for attempted suicide. Conclusion: A public health strategy for suicide prevention includes implementing prevention strategies aimed at reducing risk factors, such as alcohol consumption and the risk of neglect abuse.

Cannabis and anhedonia: A systematic review.

This paper employs a systematic review to examine the correlation between anhedonia and marijuana use, exploring whether individuals with anhedonia use marijuana as a coping mechanism or if marijuana use plays a role in the onset of anhedonia. The search utilised PubMed and Web of Science databases, following PRISMA guidelines for paper selection. A total of 21 papers were selected to address this inquiry, and assessments were carried out using the Risk of Bias in Non-randomized Studies of Exposures (ROBINS-E) tool. The results revealed that 17 studies exhibited moderate and low risk of bias. The evaluation encompassed a total of 12,427 participants, including both animals and humans. Experimental animal studies focused on exploring the association between cannabidiol (CBD) and anhedonia, while human studies primarily employed observational research, examining various forms of anhedonia in individuals with or without mental disorders such as depression or psychosis. These studies also delved into understanding the effects of anhedonia during adolescence and explored the causal relationship between these concepts. The findings indicate a reciprocal rather than unidirectional relationship, establishing that initial anhedonia predisposes individuals to cannabis use, and subsequent consumption significantly intensifies the anhedonia experienced. Particularly, the studies placed special emphasis on adolescents and individuals with mental disorders.
