Gender Differences in the Psychopathology of Obesity: How Relevant Is the Role of Binge Eating Behaviors?

Background: Obesity is a condition that affects humans both physically and mentally. Moreover, many psychopathological conditions can be observed in obese patients that may threaten the positive outcomes of bariatric surgery. Purpose: The aim of this study was to identify the main psychopathological correlates of obese candidates for bariatric surgery, with particular attention on the relationship between psychopathology and gender. Methods: In total, 273 candidates for bariatric surgery for obesity underwent a psychiatric evaluation using a compilation of psychometric scales: the Revised Symptom Checklist 90-R (SCL-90-R), the Eating Disorder Examination Questionnaire (EDE-Q), the Binge Eating Scale (BES), the Body Uneasiness Test (BUT) and the Obesity-Related Well-Being (ORWELL 97). The sample was divided on the basis of gender and binge eating disorder (BED) severity. Comparisons between the groups were performed using an analysis of variance model (ANOVA) or a Pearson's chi-squared test. Further, we also divided our sample into a severe binge eating group (score > 27), a mild to moderate group (18 < score < 26) and a low/no symptoms group (score < 17). Results: Male and female subjects showed different results for the BES, with higher scores reported among women (17.50 ± 9.59) compared to men (14.08 ± 8.64). Women also showed higher scores across most of the SCL-90-R domains and worse outcomes in terms of quality of life. Both women and men in the severe binge eating group reported higher scores for the SCL-90-R. Conclusion: The symptoms of BED, along with body image dissatisfaction (BID), are among the most important to investigate for candidates for bariatric surgery in order to improve the surgery outcomes. Level of evidence: Level III as the evidence came from a cohort analytic study.

Impact of sleep disorders and disease duration on neurotrophins levels in cocaine use disorder.

INTRODUCTION: Brain-derived neurotrophic factor (BDNF) and its precursor proBDNF contribute to brain plasticity and neuronal remodeling. Recently, the ratio between proBDNF and BDNF (RpB) has been proposed as a possible marker in major psychiatric disorders. Convergent lines of evidence suggest neurotrophins alterations could be involved into the pathophysiology of Cocaine Use Disorder (CUD) and insomnia. The aims of the present study are to evaluate the correlations between neurotrophins levels, insomnia and clinical features among CUD patients. MATERIALS AND METHODS: Subjects with a moderate to severe CUD were recruited. ProBDNF, BDNF and consequently RpB values were analyzed using ELISA technique. Insomnia severity index (ISI) scale was used to assess the severity of insomnia. Sociodemographic characteristics and CUD habits (e.g., years of cocaine use) were also collected. RESULTS: Twenty-four subjects (mean age 39.3 ± 6.7 years) were recruited. Correlation analysis showed that lower values of RpB were associated with higher ISI score (r = -0.469; p = 0.021), longer history of cocaine use (r = -0.584, p = 0.022) and higher amount of cocaine used (r = -0.655, p = 0.004). DISCUSSION: These preliminary findings may offer a novel insight on neurobiological alterations sustaining cocaine use. Lower RpB, as observed both in high insomnia levels and in chronic cocaine use, could induce a neuroprotective state as a synaptic homeostatic response to chronic damage. These findings also highlight the important role of neurotrophins balance on neurobiological alterations induced by cocaine misuse and insomnia, suggesting that RpB could be considered as a marker of neurotrophic and metabolic state of neural tissue.

Atypical Antipsychotic Drugs in Dual Disorders: Current Evidence for Clinical Practice.

BACKGROUND: Concurrent disorder or dual diagnosis refers to a combination of substance use disorders and mental disorders that occur in the same patient simultaneously. These conditions pose significant clinical and healthcare impacts and are often underdiagnosed, undertreated, and complex to manage. OBJECTIVE: We assessed the quality of current pharmacological recommendations for the management of dual diagnosis, particularly by evaluating the use of second-generation antipsychotics (SGA). METHODS: A literature search was performed using the PubMed and Scopus databases for publications up to September 21, 2021, without any time restrictions. The following search strings were used: (aripiprazole OR brexpiprazole OR cariprazine OR paliperidone OR risperidone OR quetiapine OR clozapine OR olanzapine) AND (psychosis OR schizophrenia OR schizoaffective) AND ("substance use disorder" OR cocaine OR alcohol OR cannabis OR heroin OR "double diagnosis" OR "dual diagnosis")) NOT (animal OR rat OR mouse) NOT (review or meta-analysis). RESULTS: The search produced a final set of 41 articles. Most patients were males and were affected by schizophrenia, with cannabis the most abused substance, followed by alcohol. Aripiprazole was the most used drug, either orally or by long-acting formulations, followed by risperidone with oral and long-acting formulations, clozapine, olanzapine, and quetiapine. CONCLUSION: The findings highlight the use of SGA for the treatment of psychotic symptoms in comorbidity with substance use. Future studies on people with dual diagnosis and focused on long-term evaluations are warranted and need to investigate the efficacy of newly introduced molecules, such as partial D2 agonists and longacting injectable antipsychotics.

Trazodone Add-on in COVID-19-related Selective Serotonin Reuptake Inhibitor-resistant Post-traumatic Stress Disorder in Healthcare Workers: Two Case Reports.

COVID-19 represents a significant stress factor for all people worldwide due to several factors, including quarantine, lockdowns, fear of contagion, deaths, and other traumatic events. However, the healthcare workers (HCWs) have paid the higher price of this pandemic in terms of fatalities, contagions, and psychological well-being. Studies suggest that this particular population is at increased risk of developing a severe post-traumatic stress disorder (PTSD). The early diagnosis and timely treatment of PTSD in HCWs may restore well-being and significantly impact health services functioning, reducing burnout, days spent far from work, disrupted personal and team empowerment, and worse job performances. In the present article, we reported on two cases of HCWs directly involved in the treatment of COVID-19 patients who showed selective serotonin reuptake inhibitor-resistant PTSD, which was successfully treated with extended-release trazodone TRZ ContramidⓇ add-on.

Cariprazine Add-on in Inadequate Clozapine Response: A Report on Two Cases.

Cariprazine is a novel antipsychotic drug that exerts partial agonism of dopamine D2/D3 receptors with preferential binding to the D3 receptor, antagonism of 5HT2B receptors, and partial agonism of 5HT1A. Currently, cariprazine has shown clinical efficacy in patients with schizophrenia and with bipolar disorder, as well as adjunctive treatment in patients with Major Depressive Disorder (MDD) and drug-resistant MDD. In the present case series, we report on two patients with treatment-resistant schizophrenia and partial response to clozapine who benefit from combination with cariprazine. The effects of cariprazine combination were remarkable also concerning the adverse metabolic effects of clozapine.

Euthymic bipolar disorder patients and EEG microstates: a neural signature of their abnormal self experience?

BACKGROUND: A growing number of neuroimaging studies have revealed spatial abnormalities of resting-state functional brain network activity in bipolar disorder (BD). Conversely, abnormalities of resting state temporal dynamics have been scarcely investigated so far. The aim of this study was to characterize the EEG microstates activity in BD patients with a history of manic predominant polarity. Patients were euthymic and pharmacologically stabilized. METHODS: Nineteen BD patients (mean age 34.4 ± 11.0, 7 female) and 19 healthy controls (HC; mean age 38.2 ± 9.9, 7 female) were recruited. The psychometric evaluation included the Hamilton Depression Scale (HAMD), the Young Mania Rating Scale (YMRS), the Dissociative Experience Scale (DES), and the State-Trait Anxiety Inventory (STAI).  Two runs of 2 minutes of EEG activity by a 128-channel system were acquired at rest and analyzed through microstate analysis. RESULTS: We found a reduced presence of microstate B in BD patients compared to HC, since BD patients have a tendency to transit from the microstate B to the microstates C and D significantly more than HC. Furthermore, microstate B features were correlated with DES, state STAI and trait STAI scores. CONCLUSION: The reduced presence of microstate B might be associated with episodic autobiographic memory deficit, exaggerated self-focusing and states of dissociations characteristic of BD. Strong correlations of microstate B metrics and dynamics with symptoms of dissociation and anxiety across the two groups supported this interpretation.

Clozapine-related Sudden Pericarditis in a Patient Taking Long Acting Aripiprazole and Valproate: A Case Report.

Clozapine may be associated with cardiovascular adverse effects including QTc prolongation and, more rarely, with myocarditis and pericarditis. Although rare, these latter cardiovascular adverse effects may be life-threatening and must be immediately recognized and treated. Several cases of clozapine related-pericarditis have been described and often it has a subtle and insidious onset with symptoms that may be often misdiagnosed with psychiatric manifestations (e.g. anxiety, panic or somatization) leading to a delayed correct diagnosis with potential fatal consequences. In the present report we describe the case of a 27-year-old girl with schizoaffective disorder taking long acting aripiprazole and valproate who developed a sudden onset clozapine-related pericarditis during titration phase that resolved with immediate clozapine discontinuation and indomethacin administration. We underline the importance of an early diagnosis of clozapine-related pericarditis and the need to have monitoring protocols to prevent this potentially fatal adverse effect especially when polypharmacy is administered to patients taking clozapine.

Gambling disorder and bilateral transcranial direct current stimulation: A case report.

INTRODUCTION: Gambling disorder (GD) is a major public health concern with currently no validated and efficacious treatments approved. In this single case study, we report the short- and long-term effect of bilateral transcranial direct current stimulation (tDCS) of dorsolateral prefrontal cortex (DLPFC) on craving and impulse control in a subject with GD. METHODS: The patient is a 26-year-old Caucasian male with an 8-year history of GD as well as alcohol and cocaine misuse. Treatment consisted of twice-a-day stimulation for 10 days. According to the literature, both the left (to control craving) and the right (to control emotional impulses) DLPFC were stimulated. Patients subsequently received tDCS once a week for 3 months and then once every 2 weeks for another 3 months. RESULTS: After 10 days of treatment, the subject reported improved psychiatric symptoms (depression, anxiety, and impulsivity), as well as reduced gambling craving symptom severity. After 3 and 6 months of treatment, the clinical picture further improved. DISCUSSION: This is the first report of tDCS effectiveness in a single case study of GD. Therapeutic effects, both on the addictive behavior and on psychiatric comorbid symptomatology, were lasting and continued over 6 months of tDCS maintenance treatment. Future case-control studies are required to test the efficacy of this tool in patients with GD.

The Interface between Neuroscience and Neuro-Psychoanalysis: Focus on Brain Connectivity.

Over the past 20 years, the advent of advanced techniques has significantly enhanced our knowledge on the brain. Yet, our understanding of the physiological and pathological functioning of the mind is still far from being exhaustive. Both the localizationist and the reductionist neuroscientific approaches to psychiatric disorders have proven to be largely unsatisfactory and are outdated. Accruing evidence suggests that psychoanalysis can engage the neurosciences in a productive and mutually enriching dialogue that may further our understanding of psychiatric disorders. In particular, advances in brain connectivity research have provided evidence supporting the convergence of neuroscientific findings and psychoanalysis and helped characterize the circuitry and mechanisms that underlie higher brain functions. In the present paper we discuss how knowledge on brain connectivity can impact neuropsychoanalysis, with a particular focus on schizophrenia. Brain connectivity studies in schizophrenic patients indicate complex alterations in brain functioning and circuitry, with particular emphasis on the role of cortical midline structures (CMS) and the default mode network (DMN). These networks seem to represent neural correlates of psychodynamic concepts central to the understanding of schizophrenia and of core psychopathological alterations of this disorder (i.e., ego disturbances and impaired primary process thinking).

Anhedonia and substance dependence: clinical correlates and treatment options.

Anhedonia is a condition in which the capacity of experiencing pleasure is totally or partially lost, and it refers to both a state symptom in various psychiatric disorders and a personality trait. It has a putative neural substrate, originating in the dopaminergic mesolimbic and mesocortical reward circuit. Anhedonia frequently occurs in mood disorders, as a negative symptom in schizophrenia, and in substance use disorders. In particular, we focus our attention on the relationships occurring between anhedonia and substance use disorders, as highlighted by many studies. Several authors suggested that anhedonia is an important factor involved in relapse as well as in the transition from recreational use to excessive drug intake. In particular, anhedonia has been found to be a frequent feature in alcoholics and addicted patients during acute and chronic withdrawal as well as in cocaine, stimulant, and cannabis abusers. Furthermore, in subjects with a substance dependence disorder, there is a significant correlation between anhedonia, craving, intensity of withdrawal symptoms, and psychosocial and personality characteristics. Therefore treating anhedonia in detoxified alcohol-dependent subjects could be critical in terms of relapse prevention strategies, given its strong relationship with craving.

Risk factors for attempting suicide in prisoners.

We wished to examine determinants of suicidal behavior in prisoners. 903 male prisoners had a psychiatric interview which included various psychometric tests. Suicide attempters were compared with prisoners who had never attempted suicide. Significantly more of the attempters had a history of psychiatric disorder, substance abuse, a family history of suicidal behavior, convictions for violent crime, had exhibited aggressive behavior in jail, and had higher BGLHA aggression scores. A similar pattern of risk factors was found for prisoners with suicidal ideation. A lifetime history of attempting suicide, or of having suicidal ideation, is frequent in prisoners. Risk factors include family, developmental, aggression, personality, psychiatric, and substance abuse factors.

Aggression, impulsivity, personality traits, and childhood trauma of prisoners with substance abuse and addiction.

INTRODUCTION: The aim of our study is then to analyze psychological and judicial features of a subgroup of inmates with substance abuse. METHODS: Prisoners with substance abuse (n = 312) were compared to prisoners without substance abuse (n = 591). Recruited inmates completed a semistructured interview for collection of sociodemographic and judicial data and a battery of psychometric tests for assessement of aggression, impulsivity, depression, personality traits, hostility, resilience, and childhood trauma. RESULTS: Substance abusers had on average multiple incarcerations (78.8%), more juvenile convictions (60.2%), more violent behaviors during detention (29.8%), and a history of one or more suicide attempts (20.8%). They also had higher scores on subscales for childhood trauma, higher scores for psychoticism and neuroticism, higher impulsivity levels, worse resilience, increased hostility, and prevalent suicidal ideation. CONCLUSION: Prisoners with substance abuse constitute a subgroup with increased judiciary and psychiatric issues, possibly due to early life history and psychological characteristics, such as high impulsivity and aggressiveness, poor resilience, and higher suicidal risk.
