RESUMO
OBJECTIVE: The present paper compared vitamin D levels in adult patients with obsessive-compulsive disorder (OCD) and explored possible correlations with patients' characteristics. METHODS: Fifty outpatients with OCD, according to DSM-5 criteria, were included and assessed with the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and the Hamilton Rating Scale for Depression (HRDS). RESULTS: All the patients except one showed lower vitamin D levels than normative values (>30 nm/L). Vitamin D values of the whole sample were negatively correlated with Y-BOCS total, compulsion subscale, and some items' scores, specifically "interference from obsessions," "distress associated with obsessions," and "time spent on compulsions". The same relationships were detected in men, while women showed negative correlations between vitamin D levels and Y-BOCS compulsion subscale and "resistance to compulsions," "degree of control of compulsions," "insight" item scores. CONCLUSIONS: Our findings would indicate that vitamin D might be involved in the pathophysiology of OCD, and that it is possibly related to the severity of the disorder and to typical symptoms, with some sex-related peculiarities. Further studies are necessary to support or not our findings and to ascertain the effectiveness of vitamin D supplementation in patients with OCD.
RESUMO
OBJECTIVE: To provide evidence to the link between serotonin (5-HT), energy metabolism, and the human obese phenotype, the present study investigated the binding and function of the platelet 5-HT transporter (SERT), in relation to circulating insulin, leptin, and glycolipid metabolic parameters. METHODS: Seventy-four drug-free subjects were recruited on the basis of divergent body mass index (BMIs) (16.5-54.8 Kg/m2). All subjects were tested for their blood glycolipid profile together with platelet [3H]-paroxetine ([3H]-Par) binding and [3H]-5-HT reuptake measurements from April 1st to June 30th, 2019. RESULTS: The [3H]-Par Bmax (fmol/mg proteins) was progressively reduced with increasing BMIs (P < .001), without changes in affinity. Moreover, Bmax was negatively correlated with BMI, waist/hip circumferences (W/HC), triglycerides (TD), glucose, insulin, and leptin, while positively with high-density lipoprotein (HDL) cholesterol (P < .01). The reduction of 5-HT uptake rate (Vmax, pmol/min/109 platelets) among BMI groups was not statistically significant, but Vmax negatively correlated with leptin and uptake affinity values (P < .05). Besides, [3H]-Par affinity values positively correlated with glycemia and TD, while [3H]-5-HT reuptake affinity with glycemia only (P < .05). Finally, these correlations were specific of obese subjects, while, from multiple linear-regression analysis conducted on all subjects, insulin (P = .006) resulting negatively related to Bmax independently from BMI. CONCLUSIONS: Present findings suggest the presence of a possible alteration of insulin/5-HT/leptin axis in obesity, differentially impinging the density, function, and/or affinity of the platelet SERT, as a result of complex appetite/reward-related interactions between the brain, gut, pancreatic islets, and adipose tissue. Furthermore, they support the foremost cooperation of peptides and 5-HT in maintaining energy homeostasis.

BACKGROUND: Highlighting the relationship between obsessive-compulsive disorder (OCD) and tic disorder (TD), two highly disabling, comorbid, and difficult-to-treat conditions, Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) acknowledged a new "tic-related" specifier for OCD, ie, obsessive-compulsive tic-related disorder (OCTD). As patients with OCTD may frequently show poor treatment response, the aim of this multicenter study was to investigate rates and clinical correlates of response, remission, and treatment resistance in a large multicenter sample of OCD patients with versus without tics. METHODS: A sample of 398 patients with a DSM-5 diagnosis of OCD with and without comorbid TD was assessed from 10 different psychiatric departments across Italy. For the purpose of the study, treatment response profiles in the whole sample were analyzed comparing the rates of response, remission, and treatment-resistance as well as related clinical features. Multivariate logistic regressions were performed to identify possible factors associated with treatment response. RESULTS: The remission group was associated with later ages of onset of TD and OCD. Moreover, significantly higher rates of psychiatric comorbidities, TD, and lifetime suicidal ideation and attempts emerged in the treatment-resistant group, with larger degrees of perceived worsened quality of life and family involvement. CONCLUSIONS: Although remission was associated with later ages of OCD and TD onset, specific clinical factors, such as early onset and presence of psychiatric comorbidities and concomitant TD, predicted a worse treatment response with a significant impairment in quality of life for both patients and their caregivers, suggesting a worse profile of treatment response for patients with OCTD.

OBJECTIVES: Pre-electroconvulsive therapy (ECT) evaluation is an essential part of ECT preparation, a standard treatment in the psychiatric field. However, no routine pre-ECT evaluation has been published so far. This preliminary study aimed to explore different practices in pre-ECT evaluation across European countries. METHODS: The data were collected as a snowball sample approach using an online survey from September 2019 to April 2020. The final analysis included data from 18 clinics placed in 16 European countries. RESULTS: Regulations on the pre-ECT evaluation were found in 9 countries. All clinics reported doing complete blood count, serum electrolytes, and renal function analysis as a part of regular laboratory testing, alongside with a cardiovascular assessment. Ten clinics reported using psychiatric scales. Six clinics reported doing a cognitive assessment, of which all had regulations on the pre-ECT evaluation. Not one evaluation had the same sets of procedures and diagnostics. CONCLUSIONS: The differences in assessment approaches mirror high variability of the pre-ECT evaluation practice across Europe. Cognitive assessment and objectification of psychiatric symptoms should be a regular part of the pre-ECT evaluation because of the monitoring of the most common adverse effect and observing the clinical response to ECT. Standardization of the pre-ECT evaluation and ECT in general would remove criticisms and opposition to the treatment, make it based on the best of our knowledge, and provide a method respectful of patients' best interests and rights.

Attention-deficit hyperactivity disorder (ADHD), has been traditionally considered a neurodevelopmental disorder affecting children and adolescents characterized by inattention, hyperactivity, disruptive behavior, and impulsivity. Although still debated, it is evident that ADHD is also present in adulthood, but this diagnosis is rarely carried out, mainly for the frequent comorbidity with other psychiatric and/or substance abuse disorders. Given the need to shed more light on the pharmacological treatment of ADHD, we performed a naturalistic review to review and comment on the available literature of ADHD treatment across the lifespan. Indeed, stimulants are endowed of a prompt efficacy and safety, whilst non-stimulants, although requiring some weeks to be fully effective, are useful when a substance abuse history is detected. In any case, the pharmacological management of ADHD appears to be still largely influenced by the individual experience of the clinicians. Further longitudinal studies with a careful and detailed characterization of participants across different phases of the lifespan are also required to provide relevant confirmations (or denials) regarding pharmacological treatments amongst the different age groups.

Ethnic differences may significantly influence the outcome of psychopharmacological treatment, in terms of prescription, adherence, clinical response, emergence of side effects, as well as pharmacokinetics and pharmacodynamics. The purpose of this review was to explore the available literature in order to provide general suggestions to help clinicians in choosing the best therapeutic option for patients, taking into account ethnicity. Although findings are sometimes controversial, the overall published studies suggest that ethnicities other than Caucasians tend to show a lower response to antidepressants and a reduced compliance. Africans tend to be more prescribed with antipsychotics, probably due to cultural stereotypes, except with clozapine, probably for their chronic benign neutropenia. Asians usually require less antipsychotic dosages than Caucasians. The differential response and side effect profile of antidepressants and antipsychotics have been related to individual intrinsic factors, to genetic make-up, but also to cultural and contextual variables. Interestingly, albeit limited data suggest ethnic-related genetic heterogeneity at the level of the serotonin transporters, the cytochromes and some neuroreceptors. Taken together, no conclusive findings are available about the role and impact of ethnicity in psychopharmacology. One of the main problems is that the majority of the studies in psychopharmacology have been conducted on Caucasians, so that there is an urgent need to have data in other populations. Furthermore, in the era of precision medicine, the role of ethnicity may be also supported by genetic analysis.

The worldwide economic crisis of the last decade, and still unresolved, led to a great recession involving all major economies. Since economic factors may influence mental wellbeing, not surprisingly a rise in poor mental health was observed in different countries, while representing a great challenge to psychiatric interventions. This paper aims at reviewing the available English literature focusing on the impact of the current economic crisis on mental health, with a special focus on depression and suicide. Available studies indicate that consequences of economic crisis, such as unemployment, increased workload or work reorganization, and reduced staff and wages, may constitute important stressing factors with a negative impact on mental health. Although data are not easily comparable in different countries, depression seems to be the most common psychiatric disorders especially in middle-aged men. Even suicide rates seem to be increased in men, mainly in countries with no public welfare or poor family relationships. All these findings require a careful attention from both governments that cut resources on public health instead of investing in it, and psychiatric associations that should implement appropriate strategies to face and to manage this sort of depression epidemic driven by economic crisis. Again, as available data suggest that the impact of the crisis might have been attenuated in countries with higher spending in social protection, they clearly urge policy makers to take into account possible health externalities associated to inadequate social protection systems.

BACKGROUND: Sexual response in obsessive-compulsive disorder (OCD) research and practice is overlooked. According to the Dual Control Model, satisfactory sexual response is based upon a balance of sexual excitation and inhibition. The assessment of sexual response in OCD may have clinical implications, such as the integration of sex therapy in psychotherapeutic intervention. The present study was aimed at comparing sexual excitation and inhibition levels between OCD patients and matched control subjects, and investigating whether obsessive beliefs might predict sexual excitation/inhibition. METHODS: Seventy-two OCD patients (mean age ± standard deviation [SD]: 34.50 ± 10.39 years) and 72 matched control subjects (mean age ± SD: 34.25 ± 10.18) were included (62.50% men and 37.50% women in both groups). The Obsessive Compulsive Inventory-Revised (OCI-R), the Obsessive Beliefs Questionnaire-46 (OBQ-46), and the Sexual Inhibition/Sexual Excitation Scales (SIS/SES) were administered. RESULTS: Patients with OCD showed significantly higher levels of sexual excitation, inhibition due to threat of performance failure, and inhibition due to threat of performance consequences than the controls. In addition, the patients with more severe symptoms showed lower excitation than those with less severe symptoms, and those with higher perfectionism had stronger inhibition due to threat of performance failure than those with lower perfectionism. CONCLUSIONS: This is the first study exploring sexual response in OCD according to the Dual Control Model. Sexual response is an impaired quality of life outcome in OCD that should be assessed in routine clinical practice. These findings support the importance of addressing specific obsessive beliefs to improve sexuality in OCD patients.

BACKGROUND: While both depression and aging have been associated with oxidative stress and impaired immune response, little is known about redox patterns in elderly depressed subjects. This study investigates the relationship between redox/inflammatory patterns and depression in a sample of elderly adults. METHODS: The plasma levels of the advanced products of protein oxidation (AOPP), catalase (CAT), ferric reducing antioxidant power (FRAP), glutathione transferase (GST), interleukin 6 (IL-6), superoxide dismutase (SOD), total thiols (TT), and uric acid (UA) were evaluated in 30 patients with mood disorders with a current depressive episode (depressed patients, DP) as well as in 30 healthy controls (HC) aged 65 years and over. Subjects were assessed with the Hamilton Depression Rating Scale (HAM-D), the Hamilton Rating Scale for Anxiety (HAM-A), the Geriatric Depression Rating Scale (GDS), the Scale for Suicide Ideation (SSI), the Reason for Living Inventory (RFL), the Activities of Daily Living (ADL), and the Instrumental Activity of Daily Living (IADL). RESULTS: DP showed higher levels than HC of AOPP and IL-6, while displaying lower levels of FRAP, TT, and CAT. In the DP group, specific correlations were found among biochemical parameters. SOD, FRAP, UA, and TT levels were also significantly related to psychometric scale scores. CONCLUSION: Specific alterations of redox systems are detectable among elderly DP.

BACKGROUND: Obsessive-compulsive disorder (OCD) and tic disorder (TD) represent highly disabling, chronic and often comorbid psychiatric conditions. While recent studies showed a high risk of suicide for patients with OCD, little is known about those patients with comorbid TD (OCTD). Aim of this study was to characterize suicidal behaviors among patients with OCD and OCTD. METHODS: Three hundred and thirteen outpatients with OCD (n = 157) and OCTD (n = 156) were recruited from nine different psychiatric Italian departments and assessed using an ad-hoc developed questionnaire investigating, among other domains, suicide attempt (SA) and ideation (SI). The sample was divided into four subgroups: OCD with SA (OCD-SA), OCD without SA (OCD-noSA), OCTD with SA (OCTD-SA), and OCTD without SA (OCTD-noSA). RESULTS: No differences between groups were found in terms of SI, while SA rates were significantly higher in patients with OCTD compared to patients with OCD. OCTD-SA group showed a significant male prevalence and higher unemployment rates compared to OCD-SA and OCD-noSA sample. Both OCTD-groups showed an earlier age of psychiatric comorbidity onset (other than TD) compared to the OCD-SA sample. Moreover, patients with OCTD-SA showed higher rates of other psychiatric comorbidities and positive psychiatric family history compared to the OCD-SA group and to the OCD-noSA groups. OCTD-SA and OCD-SA samples showed higher rates of antipsychotics therapies and treatment resistance compared to OCD-noSA groups. CONCLUSIONS: Patients with OCTD vs with OCD showed a significantly higher rate of SA with no differences in SI. In particular, OCTD-SA group showed different unfavorable epidemiological and clinical features which need to be confirmed in future prospective studies.

In these last decades, emotions and feelings, neglected for centuries by experimental sciences, have become the topic of extensive neuroscientific research. Currently, love, the most typically human feeling, can be viewed as the result of different phases (steps), each regulated by evolutionary well-conserved and integrated neural substrates. We have proposed that the early stage, generally called romantic love, is the result of the activation of the brain limbic structures regulating fear/anxiety reactions leading to changes of major neurotransmitters, such as increased monoamine levels and decreased serotonin concentrations. The second stage of love is mainly underlain by the structures regulating the attachment system and involving oxytocin and vasopressin neuropeptides and neurotrophins. This would explain why the positive effects of love can be extremely beneficial for both mental and physical health.However, available data are still limited, and the proposed models, although supported by converging data, should be considered speculative and oversimplified. The hope is that neuroscience will permit to shed light on love, one of the most intriguing, and still largely unknown mysteries of human nature.

Different findings would indicate that obsessive-compulsive disorder (OCD), a common psychiatric condition, might significantly impair intimate relationships and sexual well-being. The aim of the present study was to ascertain whether OCD outpatients with contamination/washing symptoms experience a lower sexual arousal than those experiencing other symptoms. In addition, we explored whether a higher disgust propensity/sensitivity might moderate the relation between contamination/washing symptoms and impaired sexual arousal. A total of 72 outpatients (27 with contamination/washing symptoms and 45 with other obsessive-compulsive symptoms) were selected for this study and assessed by a battery of specific rating scales. The results highlighted how OCD patients with contamination/washing symptoms and higher disgust sensitivity showed an increased propensity to inhibition due to threat of sexual performance failure and consequences. It may be speculated that the disgust sensitivity may be a mechanism involved in the impairment of this well-being domain. In conclusion, these findings suggest that the sexual wellbeing should be evaluated during routine clinical evaluation of OCD patients.

BACKGROUND: Problematic Internet use (PIU), that may be defined as the inability to control one's use of Internet with negative consequences in daily life, is an emerging problem involving primarily, but not only young generations. Different studies have shown that students are particularly vulnerable to PIU. Given the paucity of information on PIU in our country, the aim of this paper was at investigating the characteristics of PIU amongst Italian University students. SUBJECTS AND METHODS: A self-assessment questionnaire, referred by the acronym QUNT ("Questionario sull'Utilizzo delle Nuove Tecnologie"), composed by 101 items grouped together to identify a series of factors, was developed and sent through e-mail invitation to several students from three Italian Universities. RESULTS: The returned questionnaires were 3324, out of a total of 51,304 sent, with no difference between the two sexes. On the contrary, the distribution of the QUNT factors was different in the two sexes, in people living alone and in overweight subjects. Men resulted to be more involved in online recreational activities, whereas women seemed more attracted to instant messaging and generally to social networks. PIU was significantly more present in men than women. The comparisons of QUNT factor scores in the four BMI categories showed that the greater the BMI the greater the score of some factors. CONCLUSIONS: The findings of the present study indicate that the use of Internet through new technologies may exceed its real utility amongst Italian university student, with some sex-related differences. Men seem more prone to use Internet for passing time and women for social relationships. Men are also at risk of developing PIU. Again, Internet use might be a basic vulnerability factor of increasing weight gain and obesity amongst young people.

BACKGROUND: Propensity to sexual excitation and inhibition is one of the key dimensions of sexuality. Clinicians working with Obsessive-Compulsive Disorder (OCD) patients rarely assess this and other aspects of sexuality, since treatment targets generally symptom reduction. Literature on sexual functioning in OCD patients is scarce and no study has focused on symptom subtypes, nor investigated the psychological processes related to sexual response. OBJECTIVE: In the present short report, we describe an exploratory study investigating the association between symptom subtypes and propensity towards sexual excitation/inhibition in OCD patients, controlling for gender, age and antidepressant treatment. METHODS: Seventy-two OCD patients (mean age = 34.50 years, 37.50% women) completed the Obsessive-Compulsive Inventory-Revised and the Sexual Inhibition/Sexual Excitation Scales. RESULTS: Patients with more severe compulsive washing habit had a lower propensity towards excitation and a higher one towards inhibition due to threat of performance consequences (i.e., contamination with sexually transmitted diseases/having an unwanted pregnancy). Patients with more severe symptoms of checking showed a higher propensity towards inhibition due to the threat of performance consequences. Gender, age and antidepressant treatment were not related to sexual functioning. CONCLUSION: Specific OCD symptom subtypes may be associated with some psychological processes involved in sexual response. Sexual well-being should be carefully evaluated by practitioners and should be regarded as a treatment target. Future studies should investigate more comprehensively the processes involved in sexuality.
RESUMO
BACKGROUND: Increasing evidence supports a key role of Oxytocin (OT) as a modulator of social relationships in mammals. OBJECTIVE: The aim of the present study was to investigate possible sex-related differences in plasma OT levels in human beings. METHODS: Forty-five healthy men and 45 women (mean age: 34.9 ± 6.2 years), were included in the study. Plasma preparation, peptide extraction and OT radioimmunoassay were carried out according to standardized methods. RESULTS: The results showed that OT plasma levels (pg / ml, mean ± SD) were significantly higher in women than in men (4.53 ± 1.18 vs 1.53 ± 1.19, p Ë 0.001). CONCLUSIONS: The present finding demonstrates sex-related differences in plasma OT levels in humans. It is tempting to hypothesize that such differences might be related to behaviours, attitudes, as well as susceptibility to stress response, resilience and social emotions specific of women and men.
RESUMO
BACKGROUND: The aim of the present study was to appraise retrospectively the influence of valproate (VPA) and antidepressants (ADs) on the steady-state plasma concentrations of clozapine (CLZ), the prototype of various second-generation antipsychotics, norclozapine (NCLZ, its main metabolite), and their ratio (NCLZ:CLZ). METHODS: Sixty-seven psychotic patients with a prevalent diagnosis of bipolar disorder were studied. We then analyzed data altogether and subdivided them into 4 groups, according to pharmacological treatments: #1 CLZ (n = 21), #2 CLZ plus ADs (n = 13), #3 CLZ plus VPA (n = 16), and #4 CLZ plus ADs plus VPA (n = 17). RESULTS: First, significant positive between CLZ and NCLZ plasma levels (in nanograms/milliliter) and the drug daily dosages (in milligrams/kilogram of body weight) (n = 67) were observed (Spearman: rCLZ = 0.49; rNCLZ = 0.61; P < 0.001). We then normalized by given doses CLZ and NCLZ plasma levels, natural log transformed them, and performed analysis of variance factor analyses followed by pairwise comparisons, performed on the 4 groups and the 3 CLZ parameters. We identified significant drug effects on (1) CLZ plasma levels, significantly higher in group #2 versus group #1, and (2) NCLZ:CLZ ratio, lower in group #2 versus groups #1 and #3. Significant drug × gender interactions were observed in group #3, showing higher NCLZ levels and NCLZ:CLZ ratios in men compared with women. CONCLUSIONS: Despite its inherent limitations, this observational study confirms the significant increase in plasma CLZ concentrations and reduction in NCLZ:CLZ ratio when this drug was coadministered with ADs (group #2), an effect apparently counteracted by VPA (group #4). The drug × gender interactions in patients taking both CLZ and VPA (group #3) warrant further prospective study.

OBJECTIVE: The role of dopamine (DA) in romantic love is suggested by different evidence and is supported by the findings of some brain imaging studies. The DA transporter (DAT) is a key structure in regulating the concentration of the neurotransmitter in the synaptic cleft. Given the presence of DAT in blood cells, the present study aimed to explore it in resting lymphocytes of 30 healthy subjects of both sexes in the early stage of romantic love (no longer than 6 months), as compared with 30 subjects involved in a long-lasting relationship. METHODS: All subjects had no physical or psychiatric illness. The DAT was measured by means of the [3H]-WIN 35,428 binding and the [3H]-DA reuptake to resting lymphocytes membranes. Romantic love was assessed by a specific questionnaire developed by us. RESULTS: The results showed that the subjects in the early phase of romantic love had a global alteration of the lymphocyte DAT involving both a decreased number of proteins (Bmax) and a reduced functionality (Vmax). CONCLUSIONS: Taken together, these findings would indicate the presence of increased levels of DA in romantic love that, if paralleled by similar concentrations in the brain, would explain some peculiar features of this human feeling.

The aim of the present study was to investigate psychopharmacological prescribing patterns in a large sample (n = 1815) of patients suffering from obsessive-compulsive disorder (OCD) recruited in 4 Italian centers specialized in OCD, in comparison to available national and international guidelines. The centers were asked to complete a specific data sheet questionnaire on patients' therapeutic status. Statistical analyses were carried out by SPSS. The results showed that almost all patients referred to the centers of Milan, Pisa and Rome received psychotropic medications, whereas only 59.9% (313) did so in Turin. Selective serotonin reuptake inhibitors were the most used drugs ranging between 49.0% and 71.5%. Clomipramine was prescribed more often in Rome and Pisa than in Milan and Turin. The same was true for other tricyclic antidepressants. Second-generation antipsychotics were more often prescribed in Pisa and in Milan. Mood stabilizers were almost exclusively used in Pisa. Taken together, the overall findings would suggest that, although the main Italian centers specialized in OCD follow available guidelines, a certain degree of variability does exist. This may depend on the different educational background, availability of other specific therapeutic strategies, as well as varying levels of severity and comorbidity of the patients.

The COVID-19 pandemic had a great impact on adolescent mental health, with a dramatic rise in psychiatric emergencies that has challenged healthcare systems worldwide. This paper aims at focusing on reporting the authors' experience and their data collected on adolescent emergencies in 2022 in Tuscan, within the context of the "Azienda USL Toscana Nord Ovest", a large department covering about a third of Tuscany's Regional Health Service, in central Italy. The collected findings will be shortly presented and commented on, while providing insights concerning the importance of adapting healthcare systems to adequately respond to this growing crisis and the need for broader strategies to support adolescent mental health in these challenging times.
RESUMO
BACKGROUND: Diagnostic criteria are not always useful to discriminate major depression with anxious distress (ADS-D; Diagnostic and Statistical Manual for Mental Disorders, version-5 [DSM-5] criteria) from mixed depression (Koukopoulos' criteria; KMX-D). So, clinicians need alternative tools to improve their diagnostic ability and to choose the most appropriate treatment. The aim of the present study is to identify socio-demographic and clinical features that discriminate patients with ADS-D from those with KMX-D. METHODS: Two hundred and forty-one consecutive outpatients with unipolar (51%) and bipolar (49%) disorder, fulfilling DSM-5 criteria for a current major depressive episode (MDE) and with a 21-item Hamilton Depression Rating Scale score ≥ 14, were recruited and treated in a prospective observational study. RESULTS: Ten percent of patients met criteria for KMX-D, 22% ADS-D, and 37% for both. Irritable premorbid temperament, mixed depression polarity at onset, mixed depression recurrence, and a high number of mania symptoms at intake were typical features of patients with KMX-D. Depressive polarity at onset, a low number of mania symptoms at intake, and generalized anxiety disorder comorbidity were typical features of patients with ADS-D. Multinomial logistic regression confirmed that higher rate of irritable temperament and higher Young Mania Rating Scale total score differentiated patients with KMX-D from patients with pure MDE. CONCLUSION: Our findings suggest some clinical features that could help differentiate between ADS-D and KMX-D in patients meeting both conditions and to select the appropriate treatment. However, the small sample size may have limited the power to detect differences between the groups. Further research is needed to confirm the results of present study.
