RATIONALE: Corticotropin-releasing factor (CRF), the apical stress-inducing hormone, exacerbates stress and addictive behaviors. TCAP-1 is a peptide that directly inhibits both CRF-mediated stress and addiction-related behaviors; however, the direct action of TCAP-1 on morphine withdrawal-associated behaviors has not previously been examined. OBJECTIVE: To determine whether TCAP-1 administration attenuates behavioral and physiological consequences of morphine withdrawal in mice...

Substance use disorders (SUDs) are the most costly and prevalent psychiatric conditions. Recent calls emphasize a need for biomarkers-measurable, stable indicators of normal and abnormal processes and response to treatment or environmental agents-and, in particular, brain-based neuromarkers that will advance understanding of the neurobiological basis of SUDs and clinical practice. To develop neuromarkers, researchers must be grounded in evidence that a putative marker (i) is sensitive and specific to the psychological phenomenon of interest, (ii) constitutes a predictive model, and (iii) generalizes to novel observations (e...

Adolescence is a developmental phase that exposes young people to exploratory behaviors, including substance abuse. In Switzerland, recreational ketamine use among young people is on the rise and is likely to lead to irreversible somatic complications. Primary care physicians play an essential role in identifying ketamine users, and should offer brief interventions, risk-reduction advice and a psychosocial assessment of the situation, involving close relatives. In the event of secondary damage, particularly urological damage, coordinated management by specialists is essential to achieve symptom regression...

OBJECTIVE: Decades of research has found support for the motivational model of alcohol use at the between-person level, yet research on event-level drinking motives is in its nascent stage. Similarly, drinking context has been largely ignored in studies of day-level motives. Therefore, the present study sought to test whether drinking context mediates the relation between affect and motivation on drinking outcomes at both day and person levels. METHOD: Emerging adults who drank in solitary and social settings ( N = 107; 61...

Background: The stigma and discrimination experienced by individuals with an alcohol/substance use disorder often extends to the family members and friends who provide care, which is known as courtesy stigma. This courtesy stigma can lead to isolation, poor mental health and might impact the quality-of-care these individuals provide. The aim of this study was to examine the frequency of experienced courtesy stigma/discrimination in individuals in a family support service for a loved one's substance use, and to examine any cross-sectional associations with changes in mood, health- and social-related outcomes...

The preservation of genome integrity requires specialised DNA damage repair (DDR) signalling pathways to respond to each type of DNA damage. A key feature of DDR is the integration of numerous post-translational modification signals with DNA repair factors. These modifications influence DDR factor recruitment to damaged DNA, activity, protein-protein interactions, and ultimately eviction to enable access for subsequent repair factors or termination of DDR signalling. SUMO1-3 (small ubiquitin-like modifier 1-3) conjugation has gained much recent attention...

Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most widely used and prescribed medications because of their important role in reducing inflammation and pain, in addition to their non-addictive properties and safety profiles. However, some studies have documented an association between NSAIDs and delayed union or nonunion of joint arthrodesis procedures due to a potential inhibition of the bone's inflammatory healing response. As a result, some orthopedic surgeons hesitate to prescribe NSAIDs after an arthrodesis procedure...

Multiple diagnoses are the rule in Mental Health and alcohol use disorder (AUD) is a psychopathology with many comorbidities, requiring interventions that consider common factors, which means using a transdiagnostic perspective. This study aimed to identify in the scientific literature the main common transdiagnostic factors that link AUD to other psychopathologies in people over 18 years of age. A systematic review of the literature was carried out in the portals of the databases Pubmed, PsychINFO and CAPES...

BACKGROUND: The nucleus accumbens (NAc) is a key node of the brain reward circuit driving reward-related behavior. Dysregulation of NAc has been demonstrated to contribute to pathological markers of addiction in substance use disorder (SUD) making it a potential therapeutic target for brain stimulation. Transcranial focused ultrasound (tFUS) is an emerging non-invasive brain stimulation approach that can modulate deep brain regions with a high spatial resolution. However, there is currently no evidence showing how the brain activity of NAc and brain functional connectivity within the reward network neuromodulated by tFUS on the NAc...

BACKGROUND: Nyaope is one of the commonly used drugs in many low socio-economic communities in South Africa. Because of its highly addictive properties, the vast majority of users are not able to quit, which results in long-term difficulties for their families. AIM: The aim of this study was to explore and describe the experiences of families living with nyaope users in a township in Tshwane Metropolitan Municipality. SETTING: Data were collected at the Social Development Centre, which serves a variety of social needs of families, including the various needs of families whose problems emanate from nyaope use...

Individuals with methamphetamine use disorder (MUD) often experience anxiety and depressive symptoms during abstinence, which can worsen the likelihood of relapse. Thus, it is essential to understand the neuro-mechanism behind methamphetamine use and its associated emotional withdrawal symptoms in order to develop effective clinical strategies. This study aimed to evaluate associations between emotional withdrawal symptoms and structural covariance networks (SCNs) based on cortical thickness (CTh) across the brain...

The rise of psychedelics in contemporary medicine has sparked interest in their potential therapeutic applications. While traditionally associated with countercultural movements and recreational use, recent research has shed light on the potential benefits of psychedelics in various mental health conditions. In this review, we explore the possible role of psychedelics in the management of chronic pain and opioid use disorder (OUD), 2 critical areas in need of innovative treatment options. Pain control remains a significant clinical challenge, particularly for individuals with OUD and those who receive long-term opioid therapy who develop marked tolerance to opioid-induced analgesia...

Background : Prior research has discovered an association between vaping activities and increased delinquent behaviors. However, this relationship has been exclusively studied among adolescents and has not been examined among an adult sample. Methods : The current study uses a nationally representative sample of approximately 45,000 adults from the 2021 National Survey on Drug Use and Health. Logistic regression and negative binomial regression are employed to assess the association between three types of vaping (marijuana, nicotine, flavor) and five crime measures (arrest, sold drugs, stole >$50, attack, crime index), net of covariates...

BACKGROUND: Stimulant-related overdoses have increased dramatically, with almost 50% of overdoses in the United States now involving stimulants. Additionally, harm-reduction approaches are increasingly seen as key to reducing the negative impact of substance use. Contingency management (CM), the provision of financial incentives for abstinence, is the most effective treatment for stimulant use disorder, but historically has not been widely implemented. Many recent, large-scale implementation efforts have relied upon foundational CM protocols that may not sufficiently account for recent increases in the prevalence and lethality of stimulant use nor the growing preference for harm reduction versus abstinence-only frameworks...

BACKGROUND: Perinatal substance use can have significant adverse effects on maternal and child health and family stability. Few interventions are specifically designed to address this significant public health problem. The Parent-Child Assistance Program (PCAP) is a 3-year case management and home-visiting intervention that seeks to help birthing persons with at-risk substance use during pregnancy to achieve and maintain substance use disorder recovery and avoid exposing future children to substances prenatally...

BACKGROUND: In Singapore, where drug use is a highly stigmatized and criminalized issue, there is limited understanding of the challenges faced by individuals, particularly sexual minority men, in their journey towards recovery from substance dependence or addiction. This qualitative study aimed to investigate the driving forces behind drug use, the factors contributing to drug cessation, and the elements influencing the recovery process. METHODS: Data were extracted from clinical records provided by  The Greenhouse Community Services Limited between January 2020 to May 2022...

INTRODUCTION: Electronic cigarettes and "vaping" have become popular since their appearance in Europe and the USA in approximately 2006. They are often perceived as having fewer health risks than conventional cigarettes, which makes them of interest as a support tool in smoking cessation. However, its efficacy regarding cessation or reduction of smoking under real-life conditions remains controversial. Our objective was to clarify this question in an observational study of smoking habits after initiating vaping without targeted intervention, as compared to a validated cessation programme...

BACKGROUND: Traditional epidemiological evidence suggests various associations exist between alcohol and mental/cognitive health outcomes. However, whether these reflect causal relationships remains unclear. Mendelian randomization (MR) - a kind of instrumental variable analysis using genetic variants to proxy for an exposure of interest - has the potential to improve causal inference from observational data. SUMMARY: In the first part of this review, the challenges of causal inference in the field are discussed, and a theoretical and practical introduction to the technique of MR is given...

OBJECTIVE: Previous studies have established an understanding of reasons for e-cigarette use and associated e-cigarette use patterns such as use frequency, yet the critical extension to associated e-cigarette dependence outcome remains under-researched. This study used longitudinal data to examine whether the reasons for e-cigarette use predict a higher/lower level of e-cigarette dependence. METHODS: This study recruited college students who were current e-cigarette users from Fall 2019 to Fall 2020 (four semesters) at three public universities in the Midwest and South of the U...

BACKGROUND: The U.S. opioid overdose crisis persists. Outpatient behavioral health services (BHS) are essential components of a comprehensive response to opioid use disorder and overdose fatalities. The Helping to End Addiction Long-Term® (HEALing) Communities Study developed the Communities That HEAL (CTH) intervention to reduce opioid overdose deaths in 67 communities in Kentucky, Ohio, New York, and Massachusetts through the implementation of evidence-based practices (EBPs), including BHS...
