In recent years, the online sale of kratom ( Mitragyna speciosa ), a Southeast Asian plant with both medicinal and psychoactive properties, has raised health concerns mainly due to the uncontrolled diffusion of adulterated kratom-related products. This exploratory study provides, for the first time, a snapshot of the availability of kratom products on the darknet which has been further validated by data searches on the surface web. A total of 231 listings of kratom across 23 darknet marketplaces were identified between March 2020 and October 2021. Among these, 40 were found actively sold across five markets by thirteen vendors. Listed items were mainly advertised as "safe" substitutes for medicinal products for the self-management of pain and other health conditions and offered in various forms (e.g., dry leaf powder, pills, capsules). Purchases were made using cryptocurrencies, with some vendors offering Pretty Good Privacy, and were shipped from Europe, Australia, the United States, and the United Kingdom. Goods sold by the same sellers also included illicit drugs and fraud-related products. Our study discovered a previously unknown diffusion of kratom products on the darknet mainly for self-treating a variety of medical conditions, suggesting the need for further research and immediate interventions to safeguard the well-being and health of kratom consumers.

Objective: This study aims to explore the prevalence, characteristics, and psychopathology related to Problematic Use of Internet (PUI), including Internet Addiction (IA), within a sample of psychiatric outpatients., Methods: 143 psychiatric stable outpatients (18-65, mean age: 49; F=84) were included in this study, regardless of their categorical diagnosis. Socio-demographic, clinical, psychopathological, and Internet use-related data (PIU-Scale, Internet Addiction Test, devices, use, activities) were collected across the sample., Results: The prevalence of PUI ranged between 1% (IAT) and 25% (PIU-S), with a homogeneous distribution of PUI symptoms' severity among the four main psychopathological areas (depressive, bipolar, anxiety, and psychotic disorders). PUI was correlated with age and was higher in students as in the general population. Significant associations were found between PUI symptoms and both personality and eating disorders; PUI was also positively correlated with the presence of other addictions (e.g., alcohol and/or substances). A greater proportion of patients with PUI presented other forms of behavioural addiction compared to non-symptomatic patients. Social media and online shopping, as well as video-streaming, resulted to be the main forms of PUI among patients with problematic use of the Internet., Discussion: More studies are required among students diagnosed with eating and personality disorders. The association between PUI and other addictive disorders would support the hypothesis of their common shared pathophysiology., Conclusion: Healthcare providers and educators should be made aware of such risks. More studies are needed to confirm such preliminary findings.

Objective: Obsessive and compulsive symptoms (OCS) are cross-cutting psychopathological manifestations frequently detected in a variety of clinical and non-clinical samples. It has been suggested that impaired mentalization abilities and traumatic experiences during childhood may be relevant etiopathogenetic factors in the development of OCS. The purpose of the current study was to cross-sectionally assess these variables in a non-clinical sample, testing the mediational role of mentalization abilities in the association between childhood trauma (CT) and OCS., Method: 667 participants (488 females; mean age= 29.76 ± 11.87 years; age range: 18-80) answered a survey including the Childhood Trauma Questionnaire, the Mentalization Questionnaire and the Obsession-Compulsion subscale of the Brief Symptom Inventory., Results: The mediation model was significant for the total effect (p< .001), showing that CT was positively associated with OCS (95% CI: .006; .019) and that this association was mediated by reduced levels of mentalization capacity (95% CI: .003; .009). Such results were significant controlling for potential sociodemographic and clinical confounding variables., Conclusions: The findings contribute to elucidate the complex relationships between CT, mentalization capacity, and OCS, supporting the possibility that mentalization impairments, arising from CT, may affect top-down control mechanisms thus contributing to the development of OCS., Competing Interests: Competing interests: None., (© 2024 Giovanni Fioriti Editore s.r.l.)

Interactions between childhood trauma (CT) and dissociation can contribute to psychiatric disturbances. We explored this phenomenon in relation to behavioral addictions (BAs) in a sample ( n  = 633) of young adults (age: 18-34 years). Self-report measures investigating CT, dissociation, and symptoms related to gambling disorder, internet gaming disorder, problematic social media use, exercise dependence and compulsive buying were used. Scales related to BAs were summarized into a single measure ("Total Behavioral Addiction Index" - TBAI) for inferential analyses. A model analyzing the direct and indirect effects of CT on TBAI through the mediation of pathological dissociation was performed, controlling for confounding factors. Measures on CT, dissociation, and TBAI were significantly associated with each other (all p  < .001). The total effect of CT on TBAI was significant (B = 0.063; CI: 0.045; 0.081); pathological dissociation significantly mediated such association (B = 0.023; CI: 0.013; 0.036). Our findings support the possibility that the interaction between CT and dissociation contributes to increase disturbances related to BAs.

Purpose: Studies have shown significant associations of dissociative symptoms with both eating and addictive disorders; however, the different forms of dissociation have been relatively understudied in relation to food addiction (FA). The main aim of this study was to investigate the association of certain forms of dissociative experiences (i.e., absorption, detachment and compartmentalization) with FA symptoms in a nonclinical sample., Methods: Participants (N = 755; 543 women; age range: 18-65; mean age: 28.22 ± 9.99 years) were evaluated using self-report measures of FA, dissociation, eating disturbances, and general psychopathology., Results: Compartmentalization experiences (defined as pathological over-segregation of higher mental functions) were independently associated with FA symptoms (β = 0.174; p = 0.013; CI = [0.008; 0.064]) even when confounding factors were controlled for., Conclusion: This finding suggests that compartmentalization symptoms can have a role in the conceptualization of FA, with such two phenomena possibly sharing common pathogenic processes., Level of Evidence: Level V, cross-sectional descriptive study., (© 2023.

Purpose of Review: This work aims to provide an up-to-date review of the preclinical and clinical scientific literature on the therapeutic value of kratom to better understand the underlying mechanisms related to its use and inform future therapeutic applications., Recent Findings: A growing number of studies, mainly of cross-sectional nature, describe the widespread use of kratom by individuals to self-treat pain, psychiatric symptoms, and substance use disorders (SUD) outside a controlled clinical setting. Preclinical evidence suggests kratom is effective as an analgesic agent and might decrease the self-administration of other drugs. A randomized controlled trial has further supported kratom's therapeutic value as an analgesic. Investigations in nonclinical samples of long-term kratom users also indicate its therapeutic benefit in managing SUD symptoms (e.g., craving) and long-term or acute symptoms (e.g., withdrawal) for alcohol, opioids, and other illicit drugs. However, episodes of kratom-related intoxications have also been reported, often due to the adulteration and the contamination of kratom products mainly sold online or mixed toxicities when consumed outside clinical and traditional settings., Summary: Evidence on the clinical implications of kratom use is still limited and uncertain, with kratom research constantly evolving. Therefore, further randomized trials are needed., Competing Interests: Conflict of InterestThe authors declare no competing interests., (© The Author(s) 2023.)

A wide range of comorbid conditions are associated with psoriasis, many studies have drawn attention to a higher prevalence of psychiatric comorbidities in psoriatic population. Herein, we present a case of a Caucasian 44-years-old man suffering from a severe schizophrenia, who received guselkumab (a human monoclonal antibody targeting the p40 subunit of IL-23) for the treatment of a moderate-to-severe plaque type psoriasis. After 3 months, the patient reached complete resolution of psoriasis without any side effects, maintained at 6 months follow up visit. Some studies have highlighted the hypothesis that an hyperactivation of immune response appears to be one of the main mechanisms underlying the increased risk of this association. In particular, the axis il-17/il-23 plays a central role in the pathogenesis of this disease. Further research will be needed to assess whether anti-IL23 drugs could be a more suitable therapeutic option in psoriatic patients with schizophrenia., Competing Interests: Conflict of interest: The authors declare no potential conflict of interest., (©Copyright: the Author(s).)

Suicide is a major public health problem, and it is urgent to investigate its underlying clinical and psychological concomitants. It has been suggested that low mentalization skills and problematic use of the internet (PUI) are factors that can play a role in suicidal behaviors. It is possible that poor mentalization skills contribute to leading to forms of PUI, which, in turn, can represent triggers for suicidal ideation (SI). We tested this hypothesis through a quantitative and cross-sectional study on a sample (n = 623) of young adults (age range: 18−34). Self-report measures investigating symptoms related to Social Media Addiction (SMA), Internet Gaming Disorder (IGD), mentalization capacity, and SI were used. A single mediation analysis with two mediators was carried out to evaluate the direct and indirect effects of mentalization on SI through the mediating role of SMA- and IGD-related symptoms, controlling for potential confounding factors (e.g., socio-demographic and addiction-related variables). The four explored variables were significantly associated with each other (all p < 0.001) across all subjects; the mediational model showed that the total effect of mentalization on SI was significant (B = −0.821, SE = 0.092 (95% CI: −1.001; −0.641)) and that both SMA- (B = −0.073, SE = 0.034 (95% CI: −0.145; −0.008)) and IGD-related symptoms (B = 0.046, SE = 0.027 (95% CI: −0.107; −0.001)) were significant mediators of such association. Our findings support the possibility that PUI severity plays a relevant role in mediating the association between low mentalization skills and levels of SI.

One of the worrying concomitants of problematic use of Internet (PUI) is aggression. Although the mechanisms underlying such link have not been completely clarified, it has been suggested that problematic use of social media and online videogames (i.e., two common forms of PUI among young adults) lead to increased sleep disturbances which, in turn, represent a relevant trigger for aggression. We have tested this hypothesis in a sample (N = 480) of young individuals (351 females and 129 males; mean age: 21.76 ± 1.92 years; range: 18-24). Self-report measures investigating symptoms related to social media addiction (SMA), Internet gaming disorder (IGD), insomnia severity, and aggression were used. Mediational models analyzing the direct and indirect associations of SMA- and IGD-related symptoms on aggression severity through insomnia-related symptoms were performed controlling for confounding factors. The models showed that the total effects of SMA-related symptoms (B = 0.018; p = .010) and of IGD-related symptoms (B = 0.018; p = .041) on aggression severity were significant and that these associations were mediated by insomnia-related symptoms (respectively, p < .001 and p = .003). Our findings support the potential mediating role of insomnia severity in the association of SMA- and IGD-related disturbances with levels of aggression., (© 2021 Wiley Periodicals LLC.)

Purpose: Although the association between problematic use of the internet and eating disorders (EDs) in young adults has been previously established, its underlying mechanisms have not been completely clarified. It has been suggested that exposure to idealized very thin and toned body images (e.g., "thinspiration" and "fitspiration" trends) on social media might lead to increased feelings of body dissatisfaction which, in turn, can represent a trigger for EDs. We have tested this hypothesis in a sample (N = 721) of young adults (504 females, mean age: 24.13 ± 3.70 years; range 18-34)., Methods: Self-report measures investigating symptoms related to social media addiction (SMA), muscle dysmorphia (MD), and EDs were used. A mediational model analyzing the direct and indirect effects of SMA-related symptoms on ED-related symptoms through the mediating role of MD-related symptoms was performed controlling for confounding factors (e.g., socio-demographic variables, substances use, body mass index, psychopathological distress)., Results: The model showed that the total effect of SMA-related symptoms on ED-related symptoms was significant (B = 0.213; p = 0.022) and that this association was mediated by MD-related symptoms (B = 0.083; p = 0.021)., Discussion: Our findings support the possibility that MD-related symptoms play a relevant role in mediating the association between SMA severity and ED pathology., Level of Evidence: Level III, evidence obtained from well-designed cohort or case-control analytic studies., (© 2021.

Introduction: Kratom (Mitragyna speciosa) is a tropical plant traditionally used as an ethnomedicinal remedy for several conditions in South East Asia. Despite the increased interest in its therapeutical benefits in Western countries, little scientific evidence is available to support such claims, and existing data remain limited to kratom's chronic consumption., Objective: Our study aims to investigate (pre)clinical evidence on the efficacy of kratom as a therapeutic aid and its safety profile in humans., Methods: A systematic literature search using PubMed and the Medline database was conducted between April and November 2020., Results: Both preclinical (N = 57) and clinical (N = 18) studies emerged from our search. Preclinical data indicated a therapeutic value in terms of acute/chronic pain (N = 23), morphine/ethanol withdrawal, and dependence (N = 14), among other medical conditions (N = 26). Clinical data included interventional studies (N = 2) reporting reduced pain sensitivity, and observational studies (N = 9) describing the association between kratom's chronic (daily/frequent) use and safety issues, in terms of health consequences (e.g., learning impairment, high cholesterol level, dependence/withdrawal)., Conclusions: Although the initial (pre)clinical evidence on kratom's therapeutic potential and its safety profile in humans is encouraging, further validation in large, controlled clinical trials is required., (© 2021 The Authors.

Introduction: The clinical encounter is still at the core of the psychiatric evaluation. Since the diagnostic process remains basically clinical in nature, several authors have addressed the complexity of the clinical reasoning process and highlighted the role played by intersubjective phenomena and clinician's feelings. Some recent studies have supported the view of a significant link between the clinician's subjective experience during the assessment and the diagnosis made. In a globalized world, this issue requires a careful reflection, since cultural differences may affect the intersubjective atmosphere of the encounter, which may indirectly influence the clinician's thinking., Methods: We used a previously validated instrument, named Assessment of Clinician's Subjective Experience (ACSE), to compare the clinician's subjective experience during the evaluation of Italian patients with the subjective experience of the same clinician during the assessment of foreign patients. The 2 patient groups (n = 42 each) were individually matched for known potential confounders (age, sex, categorical diagnosis, and clinical severity)., Results: We found no significant differences in mean scores on all ACSE dimensions (tension, difficulty in attune-ment, engagement, disconfirmation, and impotence), which suggests that cultural diversity did not substantially affect the clinician's subjective experience. However, the lack of information about the native country and linguistic proficiency of about a quarter of foreign patients may have limited the possibility to detect subtle or specific differences, especially with regard to the clinician's empathic attunement., Conclusions: Although further investigation is needed, our preliminary findings may have significant implications for the reflection upon the clinician's empathic experience as well as pragmatic consequences for the act of psychiatric diagnosis in the cross-cultural encounter., (© 2020 S.

Objective: Literature is quite poor about the clinical effects of novel psychoactive substances (NPS) and the long-term consequences of NPS use in psychiatric patients. Consequently, it is of the greatest interest to examine which effects NPS can exert in patients with previous severe mental illness (SMI), such as psychotic patients. The aim of this work was a comprehensive review about NPS use in patients with SMI., Methods: We searched Medline or PubMed for relevant English-language citations and reviews describing relationships between NPS use and mental disorders, as well as for the main groups of substances and associated psychiatric manifestations. All studies reporting single case or case series of patients were selected., Results: The NPS use in patients with SMI is probably underestimated. The one existing systematic review considers only 14 studies, 12 of which are case reports. Most clinical results report acute symptom exacerbation of preexisting psychosis. Paranoid, mood, and aggression symptoms occur more frequently., Conclusions: NPS use could modify clinical features of SMI, but these conclusions cannot be generalizable. More evidence is needed to establish the causal and effective connection between NPS use and course of illness, type of psychiatric symptoms, and outcome of treatment in terms of adherence or response., (Copyright © 2017 John Wiley & Sons, Ltd.)
