Pain sensitivity is modulated by affective temperament: Results from the population-based CHRIS Affective Disorder (CHRIS-AD) study.

BACKGROUND: Nociceptive pain modulation is related to psychological and psychiatric conditions. Evidence from clinical studies backs innate temperaments as potential precursors of mood symptoms and disorders, and pain sensitivity. Our study examines the modulation effect of affective temperaments on pain sensitivity in a general population adult sample, accounting for possible intervening mood symptoms, lifetime anxiety and depression, and pain treatments. METHODS: The sample is part of the CHRIS-AD study, Italy. Primary outcomes were the pain sensitivity questionnaire PSQ-total intensity score and the experimental pressure pain threshold (PPT). Affective temperaments were evaluated with the TEMPS-M. Lifetime depression, anxiety, current mood disorders, and treatments were self-reported via rating-scales. Directed acyclic graphs theory guided linear and mixed linear regression model analyses. RESULTS: Among 3804 participants (aged 18-65; response rate 78.4 %, females 53.3 %, mean age 38.4 years) for any given temperament, both the PSQ-total and the PPT were associated with temperament. The TEMPS-M four cyclothymic-related temperaments aligned on the pain-sensitive pole and the hyperthymic on the pain-resilient pole. The inclusion of current or lifetime mood symptoms, or pain drug use, as possible intervening pathways only partly diluted these associations, with stronger evidence for an effect of trait anxiety. LIMITATIONS: The main limitations were the lack of experimental measures of suprathreshold pain intensity perception, and detailed information on affective disorders in the study population. CONCLUSIONS: These findings support the hypothesis of a biological dichotomous diathesis of affective temperaments towards pain sensitivity; hyperthymic suggesting protection, whereas cyclothymic suggesting predisposition.

[Theory of mind in bipolar disorder: a review]. / La teoria della mente nel disturbo bipolare: una rassegna.

AIM: Bipolar disorder (DB) is associated with an impairment in socio-cognitive functioning in both the acute and, to a lesser extent, the euthymic phase. Several neuroimaging and behavioral studies have evaluated social cognition, especially theory of mind (ToM), in people with bipolar disorder, in attempt to identify clinical features, its role and severity. METHODS: A bibliographical research of controlled studies from January 1999 to April 2018 was completed in PubMed and PsycINFO using the keywords "Bipolar Disorder" and "Theory of mind", "Mirror neuron system". RESULTS: During the euthymic phase patients with bipolar disorder show a different pattern in different ToM tasks, compared to healthy controls. Some studies show how these anomalies also involve the mirror neuron system, a network closely connected to the neural structures underlying the ToM. LIMITATIONS: The studies evaluate only one component of social cognition and not all studies include a control group. CONCLUSIONS: Research supports the role of ToM deficits in DB as a relevant clinical element in the complex model of this disorder, especially in interpersonal functioning, offering possibilities for further research and treatment integration.

Metacognitions and repetitive negative thinking in bipolar disorder and healthy controls: A comparative study.

BACKGROUND: Metacognitive deficits and repetitive negative thinking are poorly explored in bipolar disorder (BD). The majority of the published studies concerned patients with bipolar depression, without differentiating among BD subtypes. The most common dysfunctional metacognitions, measured with the Metacognition Questionnaire-30 (MCQ-30), were Negative Beliefs about the Uncontrollability and Danger of Worry (NB), Cognitive Confidence (CC) and Beliefs about the Need to Control Thoughts (NC). Worry and rumination also seem to influence every phase of BD. This study aimed to investigate metacognitions and repetitive negative thinking in euthymic patients with BD. METHOD: Using the MCQ-30, the Penn State Worry Questionnaire (PSWQ) and the Ruminative Responses Scale (RRS), we compared 57 BD-I and 48 BD-II patients with 78 healthy controls. RESULTS: Both BD groups showed significantly higher NB, CC, NC and total MCQ-30 scores. 'Positive Beliefs About Worry' (PBW) showed a significantly higher score only in the BD-II group. Rumination scores were significantly higher in both patient samples. Worry did not show any significant differences between groups. LIMITATIONS: The primary limitations are related to the size of the samples and the research design. CONCLUSIONS: Our findings suggested that metacognitive deficits and negative repetitive thinking were associated with euthymic BD. Rumination, NB, CC, and TC may represent trait-dependent features related to the inter-episodic phase of the disorder. A higher PBW score seemed to be a distinctive feature only for patients with euthymic BD-II. The results offer new perspectives in the psychotherapeutic treatment of these patients.

Prevalence and Correlates of Vitamin D Deficiency in a Sample of 290 Inpatients With Mental Illness.

Introduction: Vitamin D inadequacy or deficiency (VDID) has been reported in a high percentage of otherwise healthy individuals. Factors that may contribute to the high prevalence of VDID in people with mental disorders include diet low in vitamin D, poor sunlight exposure, decrease in cutaneous vitamin D synthesis, intake of certain medications, poor mobility, excessive alcohol intake, and tobacco smoking. VDID has been correlated to a host of adverse conditions, including rickets, osteoporosis, osteomalacia, muscle diseases, depression, cognitive dysfunction, and even certain cancers. Objectives: The purpose of this study was to report the prevalence and correlates of vitamin D inadequacy in a sample of 290 psychiatric patients admitted to inpatient or day hospital treatment at the University of Siena Medical Center. Methods: We retrospectively evaluated the prevalence of VDID in 290 psychiatric inpatients' medical records during the year 2017 and evaluated the correlates of VDID in patients with mental illness. Results: Two hundred and seventy two out of two hundred and ninety patients (94%) showed VDID. Physical activity and regular diet were positively correlated with vitamin D levels whereas age, tobacco smoking, PTH, alkaline phosphatase levels were negatively correlated. Statistically significant differences were found among smokers and non-smokers in all study groups. Conclusions: VDID was highly prevalent in our sample. In addition to vitamin D supplementation, psychosocial intervention able to promote and help sustain physical activity, appropriate diet, quitting smoking and sensible sun exposure to prevent and treat VDID in patients with mental health should be implemented, tested, and introduced in our clinical practice.

Obsessive-compulsive Disorder with Comorbid Bipolar Disorders: Clinical Features and Treatment Implications.

BACKGROUND: Obsessive-compulsive disorder (OCD) symptoms within the context of a bipolar disorder (BD) have been described since the 19th century. Interestingly, the existence of a relevant overlap between the aforementioned psychiatric syndromes has been confirmed by a number of recent epidemiological and family studies. AIMS: The aim of the present paper is to review the clinical features and the therapeutic implications of the OCD-BD comorbidity. DISCUSSION: In the last two decades, the frequent association between OCD and BD has been earning a growing interest given its relevant nosological and therapeutic implications. Usually patients suffering from OCD-BD comorbidity show a peculiar clinical course, characterized by a larger number of concomitant depressive episodes and episodic course. In these cases, the treatment with antidepressants is more likely to elicit hypomanic or manic switches, while mood stabilizers significantly improve the overall clinical picture. Moreover, OCD-BD patients are frequently comorbid with a number of other psychiatric disorders, in particular anxiety disorders, social phobia, and different substance abuses, such as alcohol, nicotine, caffeine and sedatives. CONCLUSIONS: BD-OCD comorbidity needs further investigations in order to provide more solid evidences to give patients a more precise clinical diagnosis and a more targeted therapeutic approach.

[The neural bases of social cognition in major depressive disorder: a review]. / La cognizione sociale nel disturbo depressivo maggiore: una rassegna sulle basi neurali.

INTRODUCTION: Major depressive disorder (MDD) is associated with a significant impairment of social and interpersonal functioning. Several neuroimaging studies have evaluated social cognition, i.e. how people with MDD process, store and analyze information about other people and social situations. METHODS: We conducted a focused review and selected manuscript published until August 2016 indexed on PubMed and PsycINFO, searching for the following keywords: "major depressive disorder", "major depression", "unipolar depression", "clinical depression", "fMRI", "emotion comprehension", "emotion perception", "affect comprehension", "affect perception", "facial expression", "prosody", "theory of mind", "mentalizing", "empathy". RESULTS: During depressive episodes, patients with MDD show a difference pattern of neural response during emotion processing, compared to healthy controls. Many studies show that those alterations disappear once the acute episodes remit. However, other studies show that the alterations may persist during remission periods. Limits. The studies evaluate only one component of social cognition and not all studies include a control group. CONCLUSIONS: Neurobiological research supports a role of social cognition deficits in MDD, especially for what pertains interpersonal functioning, this suggesting the need for further research and the possibility for treatment implications.

Use of Stimulants in Bipolar Disorder.

Several international guidelines indicate stimulants, including methylphenidate (MPH), amphetamines and derivatives, modafinil, and armodafinil among the second-third-line choices for bipolar depression. Efficacy of stimulants has been also reported for the management of residual depressive symptoms such as fatigue and sleepiness and for the management of affective, cognitive, and behavioral symptoms in children and adult bipolar patients with comorbid ADHD. Few case reports show positive results with MPH in the treatment of resistant mania. Finally, MPH might be an option in some bipolar forms observed in psychiatric presentations of frontotemporal dementia and traumatic brain injury. In spite of these preliminary observations, the use of stimulants in bipolar patients is still controversial. Potential of misuse and abuse and mood destabilization with induction of (hypo)manic switches, mixed states, and rapid cycling are the concerns most frequently reported. Our aims are to summarize available literature on this topic and discuss practical management implications.

[Neural basis of social cognition in bipolar disorder]. / Le basi neurali della cognizione sociale nel disturbo bipolare.

AIM: This article review studies social and interpersonal functioning in patients with bipolar disorder (BD), and reports on the neurobiological underpinnings of the dysfunctions in emotion recognition, i.e. one of the main domains of social cognition. METHODS: A bibliographical research of controlled studies from 1967 to 2015 was completed in PubMed and PsycINFO using the keywords: "fMRI", "emotion comprehension", "emotion perception", "affect comprehension", "affect perception", "facial expression", "prosody", "theory of mind", "mentalizing", "attributional style", "social perception", "empathy" and "bipolar disorder" or "unipolar depression". RESULTS: Limbic hyperactivity, with a lack of appropriate cortical control, has been reported in subjects with BD during social interactions. This is particularly evident during the acute affective episodes but may persist during the euthymic phases. DISCUSSION: Deficits in emotion regulation, including neural systems implicated both in voluntary and automatic emotion regulatory subprocesses, are present in DB, particularly for what pertains to social interactions and interpersonal functioning. CONCLUSIONS: Patients with bipolar disorder may present a dysfunction in the cortical ability to modulate the limbic system, which may show hyperactivity during social interactions. More studies are needed, including studies to evaluate treatment implications.

Anxiety control and metacognitive beliefs mediate the relationship between inflated responsibility and obsessive compulsive symptoms.

Research has indicated that beliefs about inflated responsibility, beliefs about perceived control over anxiety-related events and reactions (anxiety control) and metacognitive beliefs about the need to control thoughts are associated with obsessive compulsive symptoms. In the current study we tested a mediation model of the interactions between these variables in predicting obsessive compulsive symptoms. Thirty-seven individuals with obsessive compulsive disorder and 31 controls completed the following self-report instruments: the Responsibility Attitude Scale, the Anxiety Control Scale, the Beliefs about Need to Control Thoughts sub-scale of the Metacognitions Questionnaire 30, and the Padua Inventory. Mann-Whitney U tests revealed that participants in the clinical group scored significantly higher than those in the non-clinical group on all variables. In the mediation model we found that the relationship between beliefs about inflated responsibility and obsessive compulsive symptoms was fully mediated by anxiety control and beliefs about the need to control thoughts. These findings provide support for the significant role played by beliefs about control in predicting the severity of obsessive compulsive symptoms.

Factor structure and reliability of the Italian adaptation of the Hypomania Check List-32, second revision (HCL-32-R2).

OBJECTIVE: To assess the psychometric properties of the Italian adaptation of the Hypomania-Check-List 32-item, second revision (HCL-32-R2) for the detection of bipolarity in major depressive disorder (MDD) treatment-seeking outpatients. METHODS: A back-to-back Italian adaption of the "Bipolar Disorders: Improving Diagnosis, Guidance, and Education" English module of the HCL-32-R2 was administered between March 2013 and October 2014 across twelve collaborating sites in Italy. Diagnostic and Statistical Manual Fourth edition (DSM-IV) diagnoses were made adopting the mini-international neuropsychiatric interview, using bipolar disorder (BD) patients as controls. RESULTS: In our sample (n=441, of whom, BD-I=68; BD-II=117; MDD=256), using a cut-off of 14 allowed the HCL-32-R2 to discriminate DSM-IV-defined MDD patients between "true unipolar" (HCL-32-R2(-)) and "sub-threshold bipolar depression" (HCL-32-R2(+)) with sensitivity=89% and specificity=79%. Area under the curve was .888; positive and negative predictive values were 75.34% and 90.99% respectively. Owing to clinical interpretability considerations and consistency with previous adaptations of the HCL-32, a two-factor solution (F1="hyperactive/elated" vs. F2="irritable/distractible/impulsive") was preferred using exploratory and confirmatory factor analyses, whereas items n.33 ("I gamble more") and n.34 ("I eat more") introduced in the R2 version of the scale slightly loaded onto F2 and F1 respectively. Cronbach׳s α=.88 for F1 and .71 for F2. LIMITATIONS: No cross-validation with any additional validated screening tool; treatment-seeking outpatient sample; recall bias; no systematic evaluation of eventual medical/psychiatric comorbidities, current/lifetime pharmacological history, neither record of severity of current MDE. CONCLUSIONS: Our results seem to indicate fair accuracy of HCL-32 as a screening instrument for BD, though replication studies are warranted.

Autonomy and Submissiveness as Cognitive and Cultural Factors Influencing Eating Disorders in Italy and Sweden: An Exploratory Study.

The aim of this exploratory study was to investigate the correlation between cultural and psychological factors in relation to predicting eating disorders in two different non-clinical Italian (n = 61) and Swedish (n = 31) female populations, thought to have different cultures and lifestyles. The Swedish sample would reflect an emancipated model of women pursuing autonomy and freedom but also an ideal of thinness, while the Italian sample would reflect a difficult transition from traditional submissiveness to modern autonomy. Both groups completed self-report instruments assessing cultural values (e.g., collectivism and individualism) and features of eating disorders (e.g., drive for thinness, bulimia, body dissatisfaction, self-esteem, parental criticism and perfectionism). Swedish women were found to display higher levels of bulimia, perfectionism, and individualism than Italian women, while regression analysis showed that in the Italian sample high levels of collectivism were correlated with measures of EDs. The results support the hypothesis that EDs are linked with both modern values of autonomy, independence and emancipation, and situations of cultural transition in which women are simultaneously exposed to traditional models of submission and opportunities for emancipation and autonomy.

Worry as an adaptive avoidance strategy in healthy controls but not in pathological worriers.

The cognitive avoidance model of worry assumes that worry has the adaptive function to keep under control the physiological arousal associated with anxiety. This study aimed to test this model by the use of a fear induction paradigm in both pathological and healthy individuals. Thirty-one pathological worriers and 36 healthy controls accepted to be exposed to a fear induction paradigm (white noise) during three experimental conditions: worry, distraction, and reappraisal. Skin conductance (SCR) and heart rate variability (HRV) were measured as indices of sympathetic and parasympathetic nervous system functioning. Worriers showed increased sympathetic and decreased parasympathetic activation during the worry condition compared to non-worriers. There were no differences between groups for the distraction and reappraisal conditions. SCRs to the white noises during worry were higher in worriers versus controls throughout the entire worry period. Intolerance of uncertainty - but not metacognitive beliefs about worry - was a significant moderator of the relationship between worry and LF/HF-HRV in pathological worriers. Results support the cognitive avoidance model in healthy controls, suggesting that worry is no longer a functional attitude when it becomes the default/automatic and pathological response.

Treatment adherence towards prescribed medications in bipolar-II acute depressed patients: relationship with cyclothymic temperament and "therapeutic sensation seeking" in response towards subjective intolerance to pain.

BACKGROUND: Treatment adherence (TA) is crucial during almost any phase of bipolar disorder (BD), including type-II (BD-II) acute depression. While a number of issues have been traditionally accounted on the matter, additional factors should be likewise involved, including affective temperaments and some clinically suggestive psychopathological traits whose systematic assessment represents the aim of this study. METHODS: Two hundred and twenty BD-II acute depressed outpatients were consecutively evaluated using the Structured Clinical Interviews for Diagnostic and Statistical Manual for Mental Disorders-Fourth Edition Axis-I and II Disorders, Hamilton scales for Depression and Anxiety, Temperament Evaluation of the Memphis Pisa Paris San Diego-Auto-questionnaire-110-item, Visual Analogue Scale (VAS), Zuckerman's Sensation-Seeking Scale-Form-V (SSS-V), Barratt's Impulsivity Scale-11-item, State-Trait Anxiety Inventory modules, Severity module of the Clinical Global Impression Scale for BD, Morisky 8-Item Medication Adherence Scale (MMAS-8) and the Clinician Rating Scale (CRS). Patients were divided into non-adherent vs. treatment-adherent cases depending on MMAS-8+CRS scores. RESULTS: In the TA(-) group, higher VAS and cyclothymic temperament scores were highly correlated (r=.699; p≤.001). Those latter scores, along with SSS-V scores and the occurrence of lifetime addiction to painkiller and/or homeopathic medications available over the counter defined a "therapeutic sensation seeking" pattern allowing to correctly classify as much as 93.9% [Exp(B)=3.490; p≤.001] of TA(-) cases (49/220). LIMITS: Lack of objective TA measures and systematic pharmacological record; recall bias on some diagnoses; and relatively small sample size. CONCLUSIONS: Stating the burden of TA in BD, additional studies on this regard are aimed, ideally contributing to enhance the management of BD itself.

Sensation seeking in major depressive patients: relationship to sub-threshold bipolarity and cyclothymic temperament.

BACKGROUND: High levels of sensation seeking (SS) have been traditionally reported for lifetime bipolar disorder (BD) and/or substance use disorder (SUD) rather than major depressive disorder (MDD). Nonetheless, a renewed clinical attention toward the burden of sub-threshold bipolarity in MDD, solicits for a better assessment of "unipolar" major depressive episodes (MDEs) via characterization of putative differential psychopathological patterns, including SS and predominant affective temperament. METHODS: Two hundred and eighty currently depressed cases of MDD and 87 healthy controls were screened using the Zuckerman's sensation seeking scale-Form-V, the Hypomania Check List-32-item (HCL-32), the Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto-questionnaire-110-item, the Barratt Impulsivity Scale-11-item, the State-Trait Anxiety Inventory modules and the Structured Clinical Interview for DSM-IV axis-I disorders. Cases were divided into HCL-32(+)(sub-threshold bipolar)/HCL-32(-)("true" unipolar depressed) depending on the HCL-32 total score. RESULTS: Upon correlation and multivariate regression analyses, the HCL-32(+) patients showed the highest levels of SS, higher prevalence of cyclothymic temperament, and higher rates of multiple lifetime axis-I co-morbidities, including SUD. LIMITS: Recall bias on some diagnoses, including BD, grossly matched healthy control group, lack of ad-hoc validated measures for ADHD, SUD, or axis-II disorders. CONCLUSIONS: In our sample, the occurrence of higher levels of SS in "sub-threshold" bipolar cases outlined a differential psychopathological profile compared to DSM-defined "true unipolar" cases of MDE. If confirmed by replication studies, these findings may aid clinicians in delivering a more accurate diagnosis and a safer use of antidepressants in some MDD cases.

[About epidemiology of suicidal behavior: an investigation in the health-service district of Brixen]. / Zur Epidemiologie suizidalen Verhaltens: Eine Untersuchung im Gesundheitsbezirk Brixen.

OBJECTIVE: Aim of this investigation is to find out how many parasuicids as well as suicides are commited and which epidemiological characteristics (sex, age, substance addictions, relationships, job, life-events and suicide attempts in past) show people who commit suicide, and people who commiting parasuicide. After that we try to find variables predicting a suicide or variables what show a vulnerability to commit suicide. METHODS: Clinicans assess patients who commit parasuicide by the WHO-Parasuicide-Monitoring-Questionnaire and suicide victims by interview with the bereaved. Afterwards, data are assimilated and aggregated. RESULTS: In this period a mean of 37 (SD = 7.78) parasuicides and 6.32 (SD = 3.79) suicides happened yearly. The sample shows different characteristics in age, sex, life-events in the run-up to the action, job situation and parasuicide(s) in past. No differences were found between relationship and substance abuse/addiction and regarding both types of suicidal behavior. CONCLUSION: The incidence concerning suicide is slightly lower; the incidence with regard to parasuicide is lower than in other samples. Demographic variables show that people commiting suicide differ from those who commit parasuicide.
