Mentalization Impairment Is Associated with Problematic Alcohol Use in a Sample of Young Adults: A Cross-Sectional Study.

Background: Alcohol is one of the most widely used drugs among adolescents and young people, and problematic alcohol use (PAU) is related to significant long-term biological, clinical, and psychosocial sequelae. Although preliminary reports have linked deficits in mentalization to increased vulnerability to addiction, no studies have specifically explored this phenomenon in relation to PAU. Methods: The association between mentalization impairment and PAU severity was investigated in a sample of 271 young adults (183 females, 65.9%; mean age: 23.20 ± 3.55 years; range: 18-34). Self-report measures investigating PAU and mentalization were administered to all participants. Results: Individuals with PAU reported a more frequent use of tobacco and illicit drugs in the last 12 months. PAU severity was negatively associated with mentalization capacity (rho = -0.21; p < 0.001), and also, when possible, confounding variables (i.e., gender, age, occupation, education, tobacco and illegal drugs use) were controlled for (rho = -0.17; p = 0.004). Conclusion: The present data showed that mentalization impairment is significantly associated with PAU among young adults, suggesting that it may have a role in the development and/or maintenance of alcohol use.

Global arginine bioavailability, a marker of nitric oxide synthetic capacity, is decreased in PTSD and correlated with symptom severity and markers of inflammation.

INTRODUCTION: Psychiatric, physical and biological aspects of posttraumatic stress disorder (PTSD) may be associated with dysfunctions in several cellular processes including nitric oxide (NO) production. NO is synthesized from arginine in a reaction carried out by NO synthase (NOS) enzymes. The recently introduced "global arginine bioavailability ratio" (GABR; ratio of arginine to [ornithine+citrulline]) has been proposed as a reliable approximation of NO synthetic capacity in vivo. The objectives of the present study were to test the hypotheses that (i) subjects with combat-related PTSD have lower GABR scores than combat controls, (ii) GABR score is inversely associated with the severity of psychopathological measures, (iii) GABR score is inversely associated with markers of inflammation. METHODS: Metabolic profiling for plasma samples (i.e. arginine, citrulline and ornithine) and inflammation markers (interleukin [IL]-6, IL-1ß, tumor necrosis factor [TNF]-α, interferon [IFN]-γ and C-reactive protein [CRP]) were assessed in 56 combat-exposed males with PTSD and 65 combat-exposed males without PTSD. We assessed severity of PTSD (Clinician Administered PTSD Scale [CAPS]) and depression (Beck Depression Inventory-II [BDI-II]) as well as history of early life trauma (Early Trauma Inventory [ETI]) and affectivity (Positive and Negative Affect Schedule [PANAS]). RESULTS: The GABR value was (i) significantly lower in PTSD subjects compared to controls (p=0.001), (ii) significantly inversely correlated with markers of inflammation including IL6 (p=0.04) and TNFα (p=0.02), and (iii) significantly inversely correlated with CAPS current (p=0.001) and lifetime (p<0.001) subscales, ETI (p=0.045) and PANAS negative (p=0.006). Adding antidepressant use or MDD diagnosis as covariates led to similar results. Adding age and BMI as covariates also led to similar results, with the exception of IL6 and ETI losing their significant association with GABR. DISCUSSION: This study provides the first evidence that global arginine bioavailability, a marker of NO synthetic capacity in vivo, is lower in veterans with PTSD and is negatively associated with some markers of inflammation as well as with measures of PTSD symptom severity, negative affectivity and childhood adverse experiences. These findings add to the accumulating evidence that specific cellular dysfunction may be associated with the symptomatology of PTSD and may help to explain the higher burden of cardio-metabolic disturbances seen in this disorder.

Psyclones: a roller coaster of life? Hidden synthetic cannabinoids and stimulants in apparently harmless products.

OBJECTIVE: The urge to gain information on a new drug marketed online as 'Psyclone' has emerged after the death of a 38-year-old man in Bolton (UK). The fatality appeared to be a consequence of smoking this psychoactive product. METHODS: From October to December 2013, qualitative searches of the Web have been carried out in English and Italian, using the keywords 'Psyclone', 'Psyclone legal high', 'Psyclone incense' and 'Psyclone research chemical' on the Google search engine and on the database provided by the Global Public Health Intelligence Network. RESULTS: Our research highlighted the existence of two psychoactive products labelled as Psyclone but with different contents and packaging: a herbal blend containing two synthetic cannabinoids (AKB-48 and 5f-PB-22) and a research chemical containing 50% ethylphenidate, 30% caffeine and 20% lidocaine. Desired and side effects of both compounds are explored in the paper. CONCLUSIONS: Being sold as a legal product, Psyclone may appeal to recreational users, who remain unaware of its real content. This is a serious public health threat, which may lead to acute intoxications and fatalities. Further studies in the field, including Internet monitoring, are therefore required.

Smoking behaviour and mental health disorders--mutual influences and implications for therapy.

Tobacco use is strongly associated with a variety of psychiatric disorders. Smokers are more likely than non-smokers to meet current criteria for mental health conditions, such as mood disorders, anxiety disorders and psychosis. Evidence also suggest that smokers with psychiatric disorders may have more difficulty quitting, offering at least a partial explanation for why smoking rates are higher in this population. The mechanisms linking mental health conditions and cigarette smoking are complex and likely differ across each of the various disorders. The most commonly held view is that patients with mental health conditions smoke in an effort to regulate the symptoms associated with their disorder. However some recent evidence suggests that quitting smoking may actually improve mental health symptoms. This is particularly true if the tobacco cessation intervention is integrated into the context of ongoing mental health treatment. In this paper we reviewed and summarized the most relevant knowledge about the relationship between tobacco use and dependence and psychiatric disorders. We also reviewed the most effective smoking cessation strategies available for patients with psychiatric comorbidity and the impact of smoking behavior on psychiatric medication.

[Italian version of Demoralization Scale: a validation study]. / La versione italiana della Demoralization Scale: uno studio di validazione.

OBJECTIVE: Demoralization and depressive symptoms are very common in chronic organic diseases. The aim of the present study is to evaluate reliability and psychometric properties of the Italian version of the Demoralization Scale (DS) in patients with advanced cancer. METHODS: The Italian version of DS was administered to a sample consisting of 100 patients affected by different forms of cancer. The following scales were also administered: Patient Health Questionnaire, Beck Depression Inventory (BDI), Mini-Mental Adjustment to Cancer (MAC) and Karnofsky Performance Status Scale. RESULTS: The total mean score of the DS was 23.9±14.5. The study showed a good degree of stability and internal consistency of DS total score (α=0.90) and the 5 factors represented by loss of meaning and purpose (α=0.69), dysphoria (α=0.72), disheartenment (α=0.84), helplessness (α=0.50) and sense of failure (α=0.74). Significant correlations were found between DS total score and BDI (r=0.74) and between DS factors and BDI (r=0.64 for loss of meaning and purpose; r=0.55 for dysphoria; r=0.71 for disheartenment; r=0.51 for helplessness; r=0.46 for sense of failure). Good correlations were also found between DS total score and Hopelessness scale of MAC (r=0,51). According to different cut-off values, between 28 and 32 patients were seriously demoralized and 40 had moderate levels of demoralization. Between 6 and 20 patients were seriously demoralized but not clinically depressed; between 16 and 31 patients with moderate levels of demoralization had no depression. CONCLUSION: Results provide further evidence that the DS is a valid and reliable instrument of high clinical relevance in patients with advanced cancer and confirm the hypothesis of the ontological difference between demoralization and depression.

[Chronic conversion somatic disorder: a case report]. / Disturbo di conversione somatico cronicizzato.

Conversion disorder is characterized by several neurological and internistical symptoms that cannot be explained by an organic cause, exacerbating after stress events. The course of this disorder is typically short: it usually lasts about two weeks, and only 20-25% of patients relapse in the following year. This paper aims to show the clinical history of a patient complaining conversion symptoms from 7 consecutive years.

Life-saving electroconvulsive therapy in a patient with near-lethal catatonia.

A young woman with bipolar I disorder and comorbid catatonia on enteral nutrition from several months, developed a form of near-lethal catatonia with weight loss, pressure sores, muscle atrophy, electrolyte imbalance, and depression of vital signs. A compulsory treatment was necessary, and informed consent was obtained from her mother for electroconvulsive therapy (ECT). After 7 ECT sessions, the patient recovered and resumed feeding. ECT may save the life of a patient with catatonia provided that legal obstacles are overcome. Clinicians should carefully evaluate patients with near-lethal catatonia, taking into account the risk of pulmonary embolism and other fatal events. The medical-legal issues, which vary across state regulations, should be addressed in detail to avoid unnecessary and potentially harmful delay in intervention.

Factors affecting interindividual differences in clozapine response: a review and case report.

OBJECTIVE: Clozapine is the most powerful new­generation antipsychotic. Although this drug leads to great therapeutic benefits, two types of undesirable conditions frequently occur with its use: side effects and resistance to treatment. Therapeutic drug monitoring of clozapine would be very useful to avoid both these situations. The necessity of monitoring the therapy is the result of a wide interindividual variability in the metabolism of clozapine. In this review, we highlight all the conditions underlying this variability, analyzing them one by one. METHODS: Relevant literature was identified through a search of MEDLINE and PubMed. In addition, the case of a treatment­resistant patient with accelerated metabolism of clozapine is reported as representative of utility of therapeutic drug monitoring in terms of clozapine dose adjustment. RESULTS: Genetic polymorphisms of cytochrome P450 enzymes and of neurotransmitter receptors; drug interactions; interactions of clozapine with other substances such as food and drink; smoking; and nonmodifiable variables such as age, ethnicity, and gender have been examined in relation to the existing scientific literature. The laboratory techniques that clinicians could use to identify these variables and adequate therapies are also reviewed.
