Early parathyroid hormone (PTH) level as a predictor of post-surgical hypoparathyroidism

INTRODUCTION

Post-operative hypocalcemia and postoperative persistent hypoparathyroidism remain the most common complications after thyroidectomy. Many approaches have been developed to prevent them, but actually, a common protocol is not yet individuated.

MATERIALS AND METHODS

We retrospectively analyzed the results of a prospectively collected database. We dosed PTH preoperatively and 4 h after surgery (PTH_4); calcium was evaluated preoperatively, on the first (I_POD) and on the second postoperative day (II_POD). Hypocalcemia was defined when calcium <8 mg/dl. PTH_4 and I_POD calcium serum levels are identified to predict postoperative hypocalcemia.

RESULTS

Three hundred and forty-eight patients were enrolled, 37 patients resulted as hypocalcemic on I_POD and 41 on the II_POD. PTH_4 is related to I_POD (p < 0.001, r = 0.45) and II_POD (p < 0.001, r = 0.44) calcemia. PTH_4-cut-off predicting I_POD hypocalcemia was 10.50 pg/ml (sensitivity: 78.7%, specificity: 72.7%). A PTH_4 value of 11.5 pg/ml is able to predict hypocalcemia during II_POD (sensitivity: 76.5%, specificity: 69.2%). We set up a combined test to predict II_POD hypocalcemia, using PTH_4 and I_POD calcium (sensitivity: 77.8%, specificity: 89.9%).

CONCLUSION

This research shows the association between PTH_4 and postoperative hypocalcemia. The PTH_4 cut-off to predict I_POD-hypocalcemia was 10.5 pg/ml. We analyzed the calcemia trend during the postoperative period and we realized a combined test using PTH_4 and I_POD-calcemia. This test improves the accuracy of the previous test. Further studies, in particular multicentric, with a larger sample are necessary to validate the combined model.

The role of income inequality as an ecological determinant of mental health: A nation-wide multilevel analysis on an Italian sample

INTRODUCTION

Income inequality, a pivotal determinant of general and mental health, operates through intricate mechanisms at various geographical scales. While established at country or region levels, the impact of lower-level (municipal or neighborhood) inequality remains inconsistent. This study explores the influence of regional- and municipal-level income inequality on individual psychological distress during the COVID-19 pandemic in Italy, employing a multilevel data analysis.

MATERIALS AND METHODS

In a post hoc analysis of data from the first wave of the pandemic (March to April 2020), three hierarchical levels were considered: individual participants, municipalities, and regions. Depressive and anxiety symptoms were measured using the PHQ-9 and GAD-7 scales, while the Gini coefficient gauged income inequality at municipal and regional levels. The analysis incorporated demographic variables as potential confounders.

RESULTS

The study encompassed 21 regions, 3,900 municipalities, and 21,477 subjects. Income inequality at both regional and municipal levels exhibited associations with distress scores, suggesting independent effects. Notably, higher distress scores were identified in southern regions with elevated inequality, despite a more substantial COVID-19 impact in the north.

DISCUSSION

Findings contribute to existing literature by emphasizing the independent impact of lower-level (municipal) and higher-level (regional) income inequality on population psychopathology. The study supports theories suggesting diverse pathways through which inequality at different levels influences health, such as potential associations with healthcare system dysfunction at the regional level and welfare dysfunction at the municipal level. The observed north-south gradient in distress scores highlights the need for psychosocial interventions to alleviate income inequality, especially in historically disadvantaged southern regions. Future research should explore the nuanced interplay between income inequality and various ecological variables to provide a comprehensive understanding of its health impact.

Current experimental and early investigational agents for cardiac fibrosis: where are we at?

INTRODUCTION

Myocardial fibrosis (MF) is induced by factors activating pro-fibrotic pathways such as acute and prolonged inflammation, myocardial ischemic events, hypertension, aging process, and genetically-linked cardiomyopathies. Dynamics and characteristics of myocardial fibrosis development are very different. The broad range of myocardial fibrosis presentations suggests the presence of multiple potential targets.

AREA COVERED

Heart failure treatment involves medications primarily aimed at counteracting neurohormonal activation. While these drugs have demonstrated efficacy against MF, not all specifically target inflammation or fibrosis progression with some exceptions such as RAAS inhibitors. Consequently, new therapies are being developed to address this issue. This article is aimed to describe anti-fibrotic drugs currently employed in clinical practice and emerging agents that target specific pathways, supported by evidence from both preclinical and clinical studies.

EXPERT OPINION

Despite various preclinical findings suggesting the potential utility of new drugs and molecules for treating cardiac fibrosis in animal models, there is a notable scarcity of clinical trials investigating these effects. However, the pathology of damage and repair in the heart muscle involves a complex network of interconnected inflammatory pathways and various types of immune cells. Our comprehension of the positive and negative roles played by specific immune cells and cytokines is an emerging area of research.

Situs viscerum inversus and abdominal aortic aneurysm: A systematic review of a rare association

Situs viscerum inversus (SVI) is a very rare condition in that abdominal and thoracic organs are located reversed. Abdominal aortic aneurysm (AAA) is a life-threatening pathology due to progressive aortic enlargement until the rupture. The association between SVI and AAA is very infrequent. The aim of this study is to identify the surgical procedures available to treat AAA in SVI. We performed a literature review of all studies about AAA in SVI patients, analyzing PubMed/MEDLINE, EMBASE, Web of Science (WOS), Google Scholar databases. The survey includes all publications until June 2023. The outcomes include demographic findings, type of surgical procedure, intraoperative and postoperative complications, follow-up. A total of 12 studies, including 12 patients, were considered eligible for the review. AAA mean size was 70.5 mm (range: 55-90 mm); the most common localization was in the infrarenal aortic portion. 6 studies reported data on elective surgery, and 6 on emergency procedures. In one case endovascular treatment was performed. No intraoperative complications are reported; 3 postoperative complications are registered. Medium follow-up period was 13.5 months (range: 3-60). According to the available literature, the treatment of AAA in SVI is feasible and does not show an incremented morbidity compared to patients with a normal visceral configuration. This treatment seems to be effective also in case of endovascular treatment. AAA treatment in SVI should be performed (especially in elective settings) in high volume centers where it is possible to bring on collaboration across different surgical specialists.

Secondary Prevention and Extreme Cardiovascular Risk Evaluation (SEVERE-1), Focus on Prevalence and Associated Risk Factors: The Study Protocol

INTRODUCTION

Despite significant improvement in secondary CardioVascular (CV) preventive strategies, some acute and chronic coronary syndrome (ACS and CCS) patients will suffer recurrent events (also called "extreme CV risk"). Recently new biochemical markers, such as uric acid (UA), lipoprotein A [Lp(a)] and several markers of inflammation, have been described to be associated with CV events recurrence. The SEcondary preVention and Extreme cardiovascular Risk Evaluation (SEVERE-1) study will accurately characterize extreme CV risk patients enrolled in cardiac rehabilitation (CR) programs.

AIM

 Our aims will be to describe the prevalence of extreme CV risk and its association with newly described biochemical CV risk factors.

AIM

Our aims will be to describe the prevalence of extreme CV risk and its association with newly described biochemical CV risk factors.

METHODS

We will prospectively enrol 730 ACS/CCS patients at the beginning of a CR program. Extreme CV risk will be retrospectively defined as the presence of a previous (within 2 years) CV events in the patients' clinical history. UA, Lp(a) and inflammatory markers (interleukin-6 and -18, tumor necrosis factor alpha, C-reactive protein, calprotectin and osteoprotegerin) will be assessed in ACS/CCS patients with extreme CV risk and compared with those without extreme CV risk but also with two control groups: 1180 hypertensives and 765 healthy subjects. The association between these biomarkers and extreme CV risk will be assessed with a multivariable model and two scoring systems will be created for an accurate identification of extreme CV risk patients. The first one will use only clinical variables while the second one will introduce the biochemical markers. Finally, by exome sequencing we will both evaluate polygenic risk score ability to predict recurrent events and perform mendellian randomization analysis on CV biomarkers.

CONCLUSIONS

Our study proposal was granted by the European Union PNRR M6/C2 call. With this study we will give definitive data on extreme CV risk prevalence rising attention on this condition and leading cardiologist to do a better diagnosis and to carry out a more intensive treatment optimization that will finally leads to a reduction of future ACS recurrence. This will be even more important for cardiologists working in CR that is a very important place for CV risk definition and therapies refinement.

Divergent emotional and autonomic responses to Cyberball in patients with opioid use disorder on opioid agonist treatment

The perception of social exclusion among patients with opioid use disorder (OUD) could be affected by long-term opioid use. This study explores the emotional and cardiac autonomic responses to an experience of ostracism in a sample of participants with OUD on opioid agonist treatment (OAT). Twenty patients with OUD and twenty healthy controls (HC) performed a ball-tossing game (Cyberball) with two conditions: Inclusion and Ostracism. We measured self-reported ratings of perceived threat towards one's fundamental needs and respiratory sinus arrhythmia (RSA) immediately after the game and 10 min after Ostracism (Reflective stage). Following ostracism, participants with OUD self-reported blunted feelings of threat to the fundamental need to belong. RSA levels were significantly suppressed immediately after ostracism and during the Reflective stage in comparison with HC, indicating an autonomic alteration in response to threatening social situations. Finally, only among HC higher perceived threats towards fundamental needs predicted increases in RSA levels, suggesting an adaptive vagal regulation in response to a perceived threat. Conversely, among patients with OUD the subjective response to ostracism was not associated with the autonomic reaction. OAT may have a protective effect against negative feelings of ostracism. However patients with OUD on OAT present poor autonomic regulation in response to social threats, which could reflect their trait hypersensitivity to social rejection.

Editorial: What is computational psychopathology, and why do we need it?

Computational Psychopathology is an emerging discipline, which is based around the theoretical and mechanistic focus of explanatory psychopathology and computational psychiatry, and reflects the general move in psychiatric research away from whole disorders to component symptoms or transdiagnostic processes. In this Editorial, we present a brief summary of these disciplines and how they combine together to form a 'Computational Psychopathology', and present a brief possible taxonomy. We highlight the papers that form part of this Special Issue, along with their place in our putative taxonomy. We conclude this Editorial by highlighting the benefits of a Computational Psychopathology for research into mental health.

Anhedonia and sensitivity to punishment in schizophrenia, depression and opiate use disorder

BACKGROUND

From a behavioural perspective anhedonia is defined as diminished interest in the engagement of pleasurable activities. Despite its presence across a range of psychiatric disorders, the cognitive processes that give rise to anhedonia remain unclear.

METHODS

Here we examine whether anhedonia is associated with learning from positive and negative outcomes in patients diagnosed with major depression, schizophrenia and opiate use disorder alongside a healthy control group. Responses in the Wisconsin Card Sorting Test - a task associated with healthy prefrontal cortex function - were fitted to the Attentional Learning Model (ALM) which separates learning from positive and negative feedback.

RESULTS

Learning from punishment, but not from reward, was negatively associated with anhedonia beyond other socio-demographic, cognitive and clinical variables. This impairment in punishment sensitivity was also associated with faster responses following negative feedback, independently of the degree of surprise.

LIMITATIONS

Future studies should test the longitudinal association between punishment sensitivity and anhedonia also in other clinical populations controlling for the effect of specific medications.

CONCLUSIONS

Together the results reveal that anhedonic subjects, because of their negative expectations, are less sensitive to negative feedbacks; this might lead them to persist in actions leading to negative outcomes.

Adrenocortical carcinoma metastasis. A long story

INTRODUCTION

Adrenocortical Carcinoma (ACC) is an uncommon adrenal tumor with a predilection for the female population.

CASE REPORT

A 55-year-old woman was referred to our attention to undergo laparoscopic cholecystectomy for symptomatic gallstone disease. She underwent a left adrenalectomy for ACC 5 years before; the follow-up was negative for relapse. During the preoperative study an Ultrasound Scanner study demonstrated a liver lesion in S6 - S7, confirmed by a Magnetic Resonance. A PET identified also a lesion on L1 vertebra. The hepatic US-guided biopsy resulted positive for ACC metastasis. After a muldisciplinary evaluation, the patients underwent a local approach to treat both hepatic and vertebral lesions. Laparoscopic cholecystectomy was performed in order to prevent biliary and pancreatic complications. The minimally invasive technique was adopted in order to reduce surgical trauma in oncological patients, even the previous abdominal surgery and percutaneous hepatic treatment. The patient is alive, with no recurrence after 12 months from local treatments.

CONCLUSION

This is a very unusual case of double ACC metastases, discovered after the end of standard follow-up and locally treated. The patient is recurrence-free 12 months after these procedures. Minimally invasive approach to treat symptomatic cholecystectomy was used in order to avoid pancreato-biliary complications. This study emphasized the necessity to realize tailored protocols for the follow-up of rare neoplasia, as ACC.

KEY WORDS

Adrenocortical carcinoma, Cholecystectomy, Liver metastasis, Thermoablation.

706 ETIOLOGICAL ROLE OF STRESS IN ACUTE CORONARY SYNDROME: THE STRESS-ACS-ACTION STUDY

Background

Acute coronary syndrome (ACS) is the main cause of mortality worldwide and despite the adherence to guidelines it is still burdened by an unacceptable risk for cardiovascular (CV) events recurrence, highlighting the need to identify other than traditional cardiovascular risk factors (CVrF) implicated in atherosclerotic plaque instability. In this regard, psychosocial stress appears to be a crucial player in the development of CV disease. Nevertheless, stress is not easy to standardize and the mechanisms by which it promotes coronary artery disease (CAD) are poorly understood.

Materials and Methods

We therefore prospectively enrolled patients with ACS, stable coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI) and subjects presenting traditional CVrF but without established CV disease. Multimodality cortisol assessment, expression of acute and chronic stress, through blood, urine and hair samples collection was ascertained at baseline. A regression analysis was performed to assess the relationships between significant variables at univariate analysis.

Results

Fifty patients were enrolled in the present study. Cortisol levels in blood and urine were numerically higher in patients with ACS compared to CAD patients and subjects with traditional CVrF only. Hair cortisol levels did not differ between the three groups. The regression analysis showed an inverse correlation (R= -,532, p&lt;0.001 and R=-,615, p&lt;0.001 respectively) between urinary cortisol (UC) and UC/creatinine ratio and left ventricular ejection fraction (LVEF).

Conclusion

The preliminary results of our study showed that patients with ACS did not have significantly higher levels of hair cortisol compared to stable patients. The finding of an inverse relationship between higher UC, UC/C ratio levels and lower LVEF values support a link between a hyperactivity of the hypothalamic-pituitary-adrenal axis and a worse ACS presentation. These preliminary data will be implemented with serial multimodality assessment of cortisol that allow potential implications in diagnosis and outcome.

Heart Rate Fractality Disruption as a Footprint of Subthreshold Depressive Symptoms in a Healthy Population

OBJECTIVE

Psychopathology (and depression in particular) is a cardiovascular risk factor independent from any co-occurring pathology. This link is traced back to the mind-heart-body connection, whose underlying mechanisms are still not completely known. To study psychopathology in relation to the heart, it is necessary to observe the autonomic nervous system, which mediates among the parts of that connection. Its gold standard of evaluation is the study of heart rate variability (HRV). To investigate whether any association exists between the HRV parameters and sub-threshold depressive symptoms in a sample of healthy subjects.

METHOD

In this cross-sectional study, two short-term HRV recordings (5 min - supine and sitting) have been analyzed in 77 healthy subjects. Here we adopted a three-fold approach to evaluate HRV: a set of scores belonging to the time domain; to the frequency domain (high, low, and very low frequencies) and a set of 'nonlinear' parameters. The PHQ-9 (Patient Health Questionnaire-9) scale was used to detect depressive symptoms.

RESULTS

Depressive symptoms were associated only with a parameter from the non-linear approach and specifically the long-term fluctuations of fractal dimensions (DFA-α2). This association remained significant even after controlling for age, gender, BMI (Body-Mass-Index), arterial hypertension, anti-hypertensive drugs, dyslipidemia, and smoking habits. Moreover, the DFA-α2 was not affected by the baroreflex (postural change), unlike other autonomic markers.

CONCLUSIONS

Fractal analysis of HRV (DFA-α2) allows then to predict depressive symptoms below the diagnostic threshold in healthy subjects regardless of their health status. DFA-α2 may be considered as an imprint of subclinical depression on the heart rhythm.

The role of Executive Attention in the association between obsessive-compulsive symptoms and relapses in Major Depressive and Bipolar Disorder

Introduction

Major Depressive (MDD) and Bipolar Disorder (BD) are chronic relapsing condition in which mood episodes are interspersed with periods of euthymia. Impairments in Executive Attention (EA) are a trait characteristic of mood disorder that persists also during remission. Similarly prefrontal dysfunctions are crucial in the genesis and maintenance of Obsessive-Compulsive Symptoms (OCS), which are highly comorbid in both MDD and BD.

Objectives

The aim of this study is to test a model in which deficits in EA mediate the relationship between the OCS and the relapse in a cohort of patients with MDD and BD.

Methods

Sixty-four euthymic subjects with BD and MDD performed the Attentional Network Task Revised (ANT-R), that gauges EA in a standard conflict task. Here we adopted a drift diffusion model to measure the task efficiency as the drift rate in incongruent trials. Patients also completed at baseline the YBOCS, a questionnaire that evaluate the severity of OCS. All the participants have been followed-up for up to 5 years and relapses have been recorded.

Results

The association between OCS and time in euthymia was fully mediated by the EA so that greater OCS were associated with poorer executive functions (beta=-0.341; p=0.006) that in turn predicted a sooner relapse (beta=0.349; p=0.005). This held true even when controlling for classic predictors of recurrence such as previous episode distance, the duration of illness and medications.

Conclusions

Treatment targeting executive functions could hence be crucial in preventing relapses in subjects with mood disorders experiencing obsessive compulsive-symptoms.

Disclosure

No significant relationships.

The role of Effortful Control and Executive Attention in Mood Disorders

In the first part of the talk I will show that using a computational approach, namely the Drift Diffusion Model, the efficiency of executive attention (EA) is associated with effortful control, the self-regulatory aspect of temperament in a sample of n=427 healthy subjects. Then I will demonstrate how, applying the same model, EA measured through the same conflict resolution task predicts longitudinally a sooner relapse in a sample of n=64 subjects with bipolar and depressive disorders. Lastly I will discuss how EA is associated with obsessive compulsive symptoms in the same clinical population and how they interact in predicting the course of illness. Altogether these results suggest that there is an association between self-reported effortful control and EA and that treatments targeting executive functions could be crucial in preventing relapses in subjects with mood disorders experiencing obsessive compulsive-symptoms.

P364 IMPORTANCE OF URIC ACID THRESHOLD IN ITS CORRELATION WITH METABOLIC SYNDROME

Background

The relationship between Hyperuricemia and Cardiovascular risk has been established but whether or not a correlation between Serum Uric Acid (SUA) and Metabolic Syndrome (MS) exists is still a matter of debate. Indeed whether SUA level is part of MS diagnosis or just a pure marker of an unfavourable metabolic profile has not been demonstrated. Besides it’s unknown whether SUA’s addition to MS definition makes a difference in terms of prognosis. In our study we focused on evaluating in a group of hypertensive patients, the correlation between MS diagnosis and SUA defined with two different cut–off: 1) ≥6 mg/dL for women and ≥7 for men (classic cut–off); 2) &gt;5.6 mg/dL for both sexes (recently proposed by the URRAH Project).

Methods

We enrolled 473 Hypertensive patients followed by the Hypertension Unit of San Gerardo Hospital (Monza, Italy), in which SUA was measured. Patients with Hyperuricemia were identified according to the two different thresholds. NCEP–ATP–III criteria were used for diagnosis of MS.

Results

MS was diagnosed in 33.6% while Hyperuricemia was found in 14.8% of subjects according to the traditional cut–off and 35.9% according to URRAH study’s cut–off. Hyperuricemia and MS coexist in 9.7% (traditional cut–off) and 17.3% (URRAH’s threshold) of the population. Hyperuricemia was more frequent in MS than in non–MS subjects (29 vs 7.6%, p–value&lt;0.0001 for cut–off 6/7 mg/dL and 51.6 vs 28.0%, p–value&lt;0.0001 for cut–off 5.6 mg/dL). Linear regression models showed that SUA is related to MS diagnosis (β = 1.597, p–value&lt;0.0001). At logistic analysis Hyperuricemia was strongly related to MS when defined by the HURRAH‘s cut–off (OR = 0.303, p–value&lt;0.0001). The same relation is weak, although significan, when Hyperuricemia was defined by the classic cut–off (OR = 0.182, p–value&lt;0.0001).

Conclusions

Hyperuricemia is related with MS diagnosis especially when defined by the recently defined cut–off of 5.6 mg/dL.

Malondialdehyde as a candidate biomarker for bipolar disorder: A meta-analysis

Malondialdehyde (MDA) represents one of the final products of lipid peroxidation that is thought to be enhanced and accelerated in patients affected by bipolar disorder (BD). Purpose of the present article is to critically summarize the available data about MDA as a candidate biomarker for BD. First, we carried out a systematic review of the literature selecting those papers that evaluated MDA levels in BD. Then, we performed two separate meta-analyses: one of the studies that compared healthy controls (HC) with unmedicated BD and one with the studies that assessed MDA levels before and after treatment in BD, showing that bipolar patients experience more oxidative stress than healthy subjects and that treatment is effective in reducing MDA levels. In the first set of studies, we also explored through a meta-regression whether age, gender and experiencing an episode specifically influenced the difference between BD and HC in MDA levels. Bipolar patients compared to healthy subjects had higher MDA levels (SMD: 0.94, 95% CI: 0.23-1.64). Age (p < 0.01), gender (p < 0.01) and the presence of a current mood episode (p < 0.01) significantly influenced MDA plasma/serum levels. Specifically, studies that included more female, older subjects and more BD in euthymia were more likely to have higher MDA levels. Finally, patients after treatment had lower levels of MDA compared to baseline (SMD: -0.52, 95% CI: -0.85 -0.19). More studies are needed to draw definitive conclusions.

Correlation between anthropometric data and preparatory maneuvers difficulties during laparoscopic right liver resections: a single center prospective study

PURPOSE

The difficulty of laparoscopic right liver resections (LRLR) is mainly associated with their poor accessibility. Anthropometric data rather than BMI was reported to predict transection time and blood loss. Aim of the study was to evaluate the correlation between anthropometric data and preparatory manoeuvres difficulties during LRLR.

METHODS

All patients who underwent LRLR requiring full right liver mobilization from November 2019 to March 2021 were prospectively included in the study. Data on surgeons' difficulty perceptions on liver mobilization (LM), isolation of right hepatic vein (RHVI), liver manageability and visibility were rated with a 5-point scale. Data on cranio-caudal liver diameters (CCliv), CHALLENGE Index (CCliv/latero-lateral abdomen diameter), times needed to LM and RHVI were collected.

RESULTS

Sixty-five patients (29 wedge and 36 anatomical resections) with a median BMI of 25.5 were analysed. One patient required open conversion due to oncological reason. No correlations between BMI and CCliv or CHALLENGE Index were found. Larger CCliv diameter correlated with longer time for both RHVI (r = 0.589, p = 0.002) and LM (r = 0.222, p = 0.049). Higher CHALLENGE index correlated with longer time for RHVI (r = 0.589, p = 0.002). The CHALLENGE index showed a linear correlation with difficulty to the isolation of RHV (r = 0.327, p = 0.045), whilst the liver manipulation difficulty increased with latero-lateral liver diameter (r = 0.244, p = 0.033). BMI had no correlation with the duration of preparatory maneuvers neither with surgeons' difficulties.

CONCLUSIONS

Anthropometric data can help to anticipate the difficulty of preparatory maneuvers during laparoscopic right liver resections.

Amiodarone in ventricular arrhythmias: still a valuable resource?

Ventricular arrhythmias still represent an important cause of morbidity and mortality, especially in patients with heart failure and reduced left ventricular ejection fraction. Amiodarone is a Class III Vaughan-Williams anti-arrhythmic drug widely used in ventricular arrhythmias for its efficacy and low pro-arrhythmogenic effect. On the other hand, a significant limitation in its use is represented by toxicity. In this review, the pharmacology of the drug is discussed to provide the mechanistic basis for its clinical use. Moreover, all the latest evidence on its role in different clinical settings is provided, including the prevention of sudden cardiac death, implanted cardioverter defibrillators, ischemic and non-ischemic cardiomyopathies. A special focus is placed on everyday clinical practice learning points, such as dosage, indications, and contraindications from the latest guidelines.

Autonomic vulnerability to biased perception of social inclusion in borderline personality disorder

BACKGROUND

Individuals with Borderline Personality Disorder (BPD) feel rejected even when socially included. The pathophysiological mechanisms of this rejection bias are still unknown. Using the Cyberball paradigm, we investigated whether patients with BPD, display altered physiological responses to social inclusion and ostracism, as assessed by changes in Respiratory Sinus Arrhythmia (RSA).

METHODS

The sample comprised 30 patients with BPD, 30 with remitted Major Depressive Disorder (rMDD) and 30 Healthy Controls (HC). Self-report ratings of threats toward one's fundamental need to belong and RSA reactivity were measured immediately after each Cyberball condition.

RESULTS

Participants with BPD showed lower RSA at rest than HC. Only patients with BPD, reported higher threats to fundamental needs and exhibited a further decline in RSA after the Inclusion condition.

CONCLUSIONS

Individuals with BPD experience a biased appraisal of social inclusion both at the subjective and physiological level, showing higher feelings of ostracism and a breakdown of autonomic regulation to including social scenarios.

Early parent-child interactions and substance use disorder: An attachment perspective on a biopsychosocial entanglement

This review aims to elucidate environmental and genetic factors, as well as their epigenetic and neuroendocrine moderators, that may underlie the association between early childhood experiences and Substance Use Disorders (SUD), through the lens of parental attachment. Here we review those attachment-related studies that examined the monoaminergic systems, the hypothalamic pituitary adrenal stress response system, the oxytoninergic system, and the endogenous opioid system from a genetic, epigenetic, and neuroendocrine perspective. Overall, the selected studies point to a moderating effect of insecure attachment between genetic vulnerability and SUD, reasonably through epigenetic modifications. Preliminary evidence suggests that vulnerability to SUDs is related with hypo-methylation (e.g. hyper-expression) of high-risk polymorphisms on the monoaminergic and hypothalamic pituitary adrenal system and hyper-methylation (e.g. hypo-expressions) of protective polymorphisms on the opioid and oxytocin system. These epigenetic modifications may induce a cascade of neuroendocrine changes contributing to the subclinical and behavioural manifestations that precede the clinical onset of SUD. Protective and supportive parenting could hence represent a key therapeutic target to prevent addiction and moderate insecure attachment.

The Relation between the Plasma Concentrations of Long-Acting Atypical Antipsychotics and Clinical Effectiveness in Patients Affected by Schizophrenia or Schizoaffective Disorder: A Comprehensive Overview

Atypical antipsychotic depot medications are currently recommended for patients with schizophrenia (SCZ) to prevent relapse and ameliorate the long-term prognosis of these patients. This review critically summarizes the available data about the association between the plasma concentrations of long-acting Second- Generation Antipsychotics (SGAs) and the clinical effectiveness of these compounds in patients affected by SCZ or schizoaffective disorder. Our question is if the measurement of these concentrations can be helpful for clinicians in predicting treatment response and clinical stabilization of patients. Bibliographic research on the main databases was performed, and 13 studies were finally included in this review. Contrasting results were found between plasma concentrations of long-acting injectable (LAI) risperidone and clinical amelioration according to rating scale scores. Data are too scanty to draw conclusions for olanzapine and paliperidone. In contrast, despite small sample sizes, data are quite concordant in showing a relation between long-acting SGA plasma concentrations and D2 receptor occupancy. Despite the preliminary encouraging results, particularly for D2 receptor occupancy, future research with larger samples will have to confirm the clinical usefulness of measuring LAI SGA plasma concentrations to predict the clinical response of patients affected by severe mental conditions such as SCZ.

Alcohol use disorders among adult children of alcoholics (ACOAs): Gene-environment resilience factors

Both genetic and early environmental factors contribute to the pathogenesis of Alcohol Use Disorder (AUD). Gender and psychopathology symptoms might further moderate this association, resulting in an impairment of both the dopaminergic and serotoninergic pathways that sustain the binge, withdrawal and craving cycle. In a sample of of adult children of alcoholic parents (ACOAs) (n = 107) we compared those with and without an AUD, on socio-demographic variables, adverse childhood experiences, psychopathology symptoms and two polymorphisms associated with an impaired serotoninergic and dopaminergic neurotransmission (5HTTLPR and Taq1A/DRD2). A logistic regression revealed that an early caring environment might lower the risk of developing an AUD. When controlling for the actual psychopathology symptoms, being male and having the genotype associated with an impaired dopaminergic neurotransmission were still associated with AUD. Results were confirmed by an unsupervised approach that showed how the clusters characterised by being male and having the high risk genotypes were still associated with AUD compared to being female without the unfavourable dopamine genotype.Our results point to the need for implementing prevention strategies aimed at creating a caring environment especially in those families with an alcoholic parent. We further suggest that psycho-education as a symptom recognition and avoiding self-medication could improve the outcome in those subjects at higher risk, especially males.

Pattern of occurrence of obsessive-compulsive symptoms in bipolar disorder

Apparent comorbidity between Bipolar Disorder (BD) and Obsessive-Compulsive Disorder (OCD) is a common condition, but its meaning has not been clarified yet. The present study aimed to evaluate the pattern of occurrence of obsessive-compulsive symptoms (OCS) in the different phases of BD. One hundred and sixty-five BD patients, 62 (37.5%) euthymic, 34 (20.6%) in hypomanic/manic phase, 43 (26%) in depressive phase and 26 (15.7%) in mixed state, were assessed with the Yale-Brown Obsessive-Compulsive Scale (YBOCS), the Hamilton Depression Rating Scale (HAM-D), the Young Mania Rating Scale (YMRS) and the Ruminative Response Scale (RRS). In the whole sample, the severity of OCS was associated to the severity of depressive symptoms. The highest severity of OCS (YBOCS total score) was observed in the mixed group and the lowest scores in the hypomanic/manic group. Our findings suggest that OCS in BD patients appear as a state-dependent phenomenon cycling with the mood phases, particularly exacerbating in the context of depressive and mixed states.

Effortful control is associated with executive attention: A computational study

INTRODUCTION

Effortful control (EC) is the self-regulatory aspect of temperament that is thought to reflect the efficiency of executive attention (EA). Findings on relationship between EC and performance on EA tasks among adults are still contradictory. This study used a computational approach to clarify whether greater self-reported EC reflects better EA.

METHODS

Four hundred twenty-seven healthy subjects completed the Adult Temperament Questionnaires and the Attention Network Task-revised, a conflict resolution task that gauges EA as the flanker effect (FE), that is, the difference in performances between incongruent and congruent trials. Here we also employed a drift-diffusion model in which parameters reflecting the actual decisional process (drift rate) and the extra-decisional time are extracted for congruent and incongruent trials.

RESULTS

EC was not correlated with the FE computed with the classic approach, but correlated positively with drift rate for the incongruent trials, even when controlling for the drift rate in the congruent condition and the extra-decisional time in the incongruent condition.

CONCLUSION

This study demonstrates an association between self-reported EC and EA among adults. Specifically, EC is not associated with overall response facilitation but specifically with a greater ability to make goal-oriented decisions when facing conflicting information.

Belief updating in bipolar disorder predicts time of recurrence

Bipolar disorder is a chronic relapsing condition in which mood episodes are interspersed with periods of wellbeing (euthymia). Shorter periods of euthymia are associated with poorer functioning, so it is crucial to identify predictors of relapse to facilitate treatment. Here, we test the hypothesis that specific valence-dependent learning patterns emerge prior to the clinical manifestation of a relapse, predicting its timing. The ability to update beliefs in response to positive and negative information was quantified in bipolar patients during euthymia, who were then monitored for 5 years. We found that reduced tendency to update beliefs in response to positive relative to negative information predicted earlier relapse. Less updating in response to positive information may generate pessimistic beliefs, which in turn can lead to more severe prodromal symptoms (e.g. sleep disturbance, irritability etc.). The results suggest that measuring valence-dependent belief updating could facilitate risk prediction in bipolar disorder.

Laparoscopic Mesogastrium Excision for Gastric Cancer: Only the Beginning

Background: Surgery, with the aid of chemotherapy and radiotherapy, is the only curative chance for gastric cancer. Unfortunately, gastric cancer had an elevated recurrence rate, primarily locally. Mesogastrium excision (MGE) during D2 lymphadenectomy has the aim to remove all possible contaminated tissue around the stomach. Methods: PubMed, EMBASE, and the Web of Science (WOS) were systematically searched for MGE reports in gastric cancer up to March 2020. The outcome reported were the number of lymph nodes retrieved, operative time (OT), overall morbidity, intra- and postoperative complications, conversion rate, and length of hospital stay. Results: A total of six studies, including 518 patients, were considered eligible for this analysis. All the studies reported laparoscopic cases. The mean number of lymph nodes retrieved was 36.7 ± 10.1. Mean OT was 240.7 ± 10.1 minutes. One case of conversion is reported. Overall morbidity was 6%. Medium estimated blood loss was 50.2 ± 39.6 mL. Overall length of stay was 10.7 ± 0.7 days. Mean follow-up was 11 ± 1.4 months. Conclusions: Only few studies evaluated this item, and according to the available evidence, MGE is a feasible technique that could be performed, also laparoscopically, in all surgical resections for gastric cancer with curative intent. Further studies are essential to establish the clear indication of this invasive procedure.

Minilaparoscopic Cholecystectomy Versus Conventional Laparoscopic Cholecystectomy: An Endless Debate

Background: Our systematic review and meta-analysis examine the impact of minilaparoscopic cholecystectomy (MLC) versus conventional laparoscopic cholecystectomy (CLC). Some authors previously compared these surgical approaches without reaching any clear conclusion, since then, further trials have been performed, but an update was needed. Materials and Methods: PubMed, EMBASE, and the CENTRAL were systematically searched for randomized controlled trials comparing MLC versus CLC up to August 2019. The outcome measures used for comparison were operative time (OT), overall morbidity, intra- and postoperative complications, conversion and reintervention rate, length of hospital stay (LOS), postoperative pain (POP), and cosmetic results. A meta-analysis of relevant studies was performed using RevMan 5.3. Results: Fifteen studies, including 863 patients, were considered eligible to collect data and entered the meta-analysis. A total of 415 patients in the MLC group versus 448 in the CLC group were compared. No statistical difference as for overall morbidity, intra- and postoperative complications, conversion and reintervention rate, LOS, and cosmetic results were retrieved among the groups. CLC results faster and MLC shows to be the least painful. Conclusions: According to the available high-level evidence, both surgical approaches resulted substantially equivalent to perform LC, with some advantages of CLC as for OT and of MLC concerning POP. As a consequence, we can conclude that either procedure is superior or inferior to the other one; actually, we are not able to suggest the adoption of any of the two on a routine basis.

Personality and widowhood increase the risk for incident depression in the two years following the first acute coronary syndrome

Objectives: Incident depression, occurring after an acute coronary syndrome (ACS) in never depressed patients, exerts a negative effect on the cardiac prognosis. Nonetheless only a few studies have evaluated the risk factor for incident depression and, particularly, no study have investigated the role of personality disorders. Therefore, the aim of this study is to verify if personality disorders represent a risk for incident depression in patients at their first ACS.Method: The study sample was selected among never depressed patients who were consecutively admitted to the Coronary Intensive Care Unit, from January 2009 to March 2012, for the first ACS. The study sample included 262 patients. The presence of depressive disorder was assessed with the Primary Care Evaluation of Mental Disorders (DSM-IV criteria), whereas its severity was evaluated with the Hospital Anxiety and Depression Scale. Evaluations were collected at baseline and at 1, 2, 4, 6, 9, 12 and 24 months of follow-up. Moreover, at baseline personality disorders were investigated with the Structured Clinical Interview for DSM-IV Axis II disorders.Results: Out of 262 subjects, a depressive disorder was diagnosed in 56 patients (21%). At baseline risk factors for incident depression were being widowed, having a distress reaction and narcissistic personality traits.Conclusion: Clinicians should keep in mind these characteristics when facing patients at their first ACS, given the detrimental effect of depression on cardiac prognosis. A psychological support should prevent the onset of incident depression in these patients.

A rare case of pancreatic splenosis and a literature review

Splenosis is a clinical condition characterized by the presence of ectopic splenic tissue in the abdominal cavity occurring after abdominal trauma or surgical procedure involving the spleen. We present a case of an 80-year-old Caucasian male who underwent splenectomy at the age of 36, with a prior diagnosis of cancer of the left kidney associated with a pancreatic neoformation. This study compare our case with similar published and reviev the Literature. KEY WORDS: Accessory spleen, Differential diagnosis, Kidney cancer,Laparotomy, Nephrectomy, Pancreas, Pancreatic splenosis, Splenosis.

Does Aberrant Right Hepatic Artery Influence the Surgical Short- and Long-term Outcome of Pancreatoduodenectomy?

BACKGROUND

Variations in vascular anatomy in pancreaticoduodenectomy for adenocarcinoma of the pancreatic head, aberrant right hepatic artery (αRHA) being the most frequent, may influence oncological outcome, surgical complexity, intra- and postoperative complications, and overall 5-year disease-free and survival rates.

MATERIALS AND METHODS

Between January 1988 and January 2018, 297 consecutive patients underwent pancreaticoduodenectomy at our Institutions and were divided into two groups: Group 1 patients were affected with αRHA; group 2 were without this vascular anomaly. The groups were retrospectively compared to identify differences in preoperative characteristics and intraoperative course, postoperative morbidity and mortality and long-term disease-free interval and overall survival. Cox regression analysis was used to investigate the role of variables statistically significant at univariate analysis in the short- and long-term outcomes.

RESULTS

Overall 44 (15%) patients had αRHA. No differences in patient characteristics were reported. The mean operative time was 451±58 minutes for group 1 and 317±27 minutes for group 2 (p<0.001), whereas mean blood losses were 729±488 ml and 508±119 ml, respectively (p<0.001). Group 1 patients had a longer stay in intensive care when compared to patients of group 2 (mean 5±2 versus 4±2 days, respectively; p<0.001). Furthermore group 1 patients had a significant longer hospitalization when compared to those of group 2 (mean 17±5 versus 15±3 days, respectively; p<0.006). No other significant differences were observed between the two groups. Cox regression analysis showed that independently of the presence of αRHA, the factors negatively affecting the 5-year survival rate were blood loss (p<0.001) and length of stay in intensive care (p<0.001).

DISCUSSION

αRHA increases the surgical complexity of pancreatoduodenectomy, negatively affecting intraoperative blood loss, length of operation, length in intensive care and hospitalization, but does not influence long-term survival and disease-free rates.

Total Versus Completion Thyroidectomy: A Multidimensional Evaluation of Long-Term Vocal Alterations

BACKGROUND

Total thyroidectomy (TT) and completion thyroidectomy (CT) are two common surgical operations that are frequently followed by vocal symptoms despite preservation of the recurrent laryngeal nerve (RLN) and of the external branch of superior laryngeal nerve (EBSLN). The aim of this study was to analyze vocal alterations through endoscopic findings, videolaryngostroboscopy (VLS), acoustic vocal parameters and impact on patients' quality of life after surgery in the absence of laryngeal nerve injury.

METHODS

We enrolled 198 patients who underwent thyroidectomy by the same surgeon. One hundred twenty-six patients underwent TT (group TT) while 72 underwent CT (group CT). All patients underwent preoperative VLS and Voice Handicap Index (VHI) assessment and postoperative VHI, VLS and Acoustic Voice Analysis with Multidimensional Voice Program Analysis 12 to 18 months after surgery.

RESULTS

We observed a statistically significant higher rate of EBSLN injury in CT compared to TT. Even in the absence of RLN and EBSLN injury, patients who underwent TT and CT presented slightly worse acoustic vocal parameters and VHI scores compared to healthy controls. Interestingly, some acoustic vocal parameters and VHI scores were significantly worse in group CT compared to group TT.

CONCLUSIONS

The higher rate of EBSLN injury in CT rather than in TT suggests a higher surgical risk in CT. The vocal parameters of loudness and self-perception of voice were significantly worse after CT, suggesting a larger trauma in patients' vocal outcome in CT if compared to TT, although these alterations were not reported as psychologically limiting daily life of patients. Nevertheless, the existence of multiple factors contributing to vocal alterations after thyroidectomy highlight the importance of a routine comprehensive functional voice analysis before and after surgery.

Dimensional structure of first episode psychosis

AIM

Current diagnostic systems, DSM-5 and ICD-10, still adopt a categorical approach to classify psychotic disorders. The present study was aimed at investigating the structure of psychotic symptomatology in both affective and non-affective psychosis from a dimensional approach.

METHODS

Participants with a first episode psychosis (FEP) were recruited from a cluster-randomized controlled trial (GET-UP PIANO TRIAL), offered to all Community Mental Health Centres (CMHCs) located across two northern Italian regions. After clinical stabilization, patients were assessed with a comprehensive set of psychopathological measures including the Positive and Negative Syndrome Scale, the Hamilton Depression Rating Scale and the Bech-Rafaelsen Mania Rating Scale. A two-step cluster analysis was performed.

RESULTS

Overall, 257 FEP patients (male, n = 171, 66.5%; mean age = 24.96 ± 4.56) were included in the study. The cluster analysis revealed a robust four-cluster solution: delusional-persecutory (n = 82; 31.9%), depressed (n = 95; 37%), excited (n = 26; 10.1%) and negative-disorganized (n = 54; 21%), thus suggesting a quadripartite structure with both affective and non-affective dimensions. Among non-affective dimensions, negative and disorganization symptoms constituted a unique construct apart from positive symptoms.

CONCLUSIONS

Symptom dimensions may represent a useful tool for dissecting the indistinct and non-specific psychopathology of FEP in order to better target specific interventions.

Emotions at the border: Increased punishment behavior during fair interpersonal exchanges in borderline personality disorder

This study evaluated whether the impairment in cooperation that characterizes individuals with borderline personality disorder (BPD) can be explained by the difficulty to use emotion regulation strategies and to accurately perceive the fairness of others' behavior. Forty-one patients with BPD and 41 sex and age matched healthy controls (HC) played the responder's role in a Modified Ultimatum Game during which they were asked to apply 3 different emotion regulation strategies: look, distancing, and reappraisal. Offer rejection rates were used as an index of punishment behavior. After the experiment, participants also rated the degree of perceived equity of the offers after receiving fair and unfair offers. Reappraisal was effective in decreasing punishment behaviors for unfair offers in both the BPD and HC groups. By contrast, BPD patients displayed a different behavior than HC when making decisions upon fair offers, independently from the regulation strategies adopted. In fact, they rejected higher rates of fair offers than HC. Further, BPD patients judged fair offers as less fair than HC. This indicates an altered judgment and decision making on fair interpersonal exchanges. In conclusion, BPD patients exhibit increased punishment behavior during fair, "favorable" social exchanges, which they tend to perceive as less fair than controls. Thus, BPD patients may be biased toward underestimating positive feedback from others. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Alexithymia and Cardiac Outcome in Patients at First Acute Coronary Syndrome

BACKGROUND

This cohort study was aimed to verify whether subjects at their first acute coronary syndrome (ACS) were more alexithymic than healthy controls (HC) and whether alexithymia can predispose patients with coronary artery disease to new major adverse cardiac events (MACE) during a 24-month follow-up period.

METHODS

The sample included 100 HC with no history of depression or ACS and 304 never depressed patients with a first-ever ACS. A total of 266 patients completed the 2-year follow-up.

RESULTS

Patients and HC reported similar Toronto Alexithymia Scale (TAS-20) scores. During the follow-up, 69 (22.69%) patients developed incident depression and 57 (18.75%) developed a new MACE. In a proportional hazard model, developing a first-ever depressive episode, but not alexithymia (hazard ratio = 1.008, 95% confidence interval = 0.984-1.033; p = 0.500), was associated with almost 3 times the risk of a recurrent cardiac event.

CONCLUSION

Incident depression, but not TAS-20 scores, represented risk factor for MACE.

Racing thoughts revisited: A key dimension of activation in bipolar disorder

BACKGROUND

Racing and crowded thoughts are frequently reported respectively in manic and mixed episodes of bipolar disorder (BD). However, questionnaires assessing this symptom are lacking. Here we aimed to investigate racing thoughts across different mood episodes of BD through a self-report questionnaire that we developed, the 34-item Racing and Crowded Thoughts Questionnaire (RCTQ). In addition to assessing its factor structure and validity, we were interested in the RCTQ's ability to discriminate mixed and non-mixed depression.

METHODS

221 BD patients and 120 controls were clinically assessed via the YMRS (mania) and the QIDS-C16 (depression), then fulfilled the RCTQ, rumination, worry, and anxiety measures. Three depression groups were operationalized according to YMRS scores: YMRS scores 2 > 6 and YMRS scores = 1 or 2, for respectively mixed and non-pure depression, and YMRS = 0 for pure-depression.

RESULTS

Confirmatory factor analysis showed that the three-factor model of the RCTQ yielded the best fit indices, which improved after the removal of redundant items, resulting in a 13-item questionnaire. Hypomanic and anxiety symptoms were the main predictors of scores; rumination was not a significant predictor. RCTQ results were similar between mixed groups and non-pure depression, and both were higher than in pure-depression.

LIMITATIONS

Patients' pharmacological treatment might have influenced the results.

CONCLUSIONS

The 13-item RCTQ captures different facets of racing thoughts heightened in hypomanic and mixed states, but also in depression with subclinical hypomanic/activation symptoms (e.g. non-pure depression characterized by enhanced subjective irritability), suggesting that it is particularly sensitive to activation symptoms in BD, and could become a valuable tool in the follow-up of patients.

Anxiety, depression, and birth outcomes in a cohort of unmedicated women

BACKGROUND

Even though most of the systematic reviews suggest that depression and anxiety are related to poor neonatal outcomes, it is not yet clear whether a dose-response effect exists.

AIM

The aim of the present study is to evaluate the amount of depressive and anxiety symptoms in a cohort of pregnant women and its effect on their newborns.

METHODS

Two hundred ninety-nine women were assessed for anxiety and depressive disorders and anxious and depressive symptoms at near monthly intervals throughout pregnancy. At the time of delivery, we collected the newborns' gestational age, birth weight and the Apgar score at 1 and 5 min.

RESULTS

Sixty-seven women were diagnosed as depressed and 43 had an anxious disorder. After controlling for confounding variables only the overall levels of anxiety during pregnancy were negatively associated with birth weight (B = -5.76; 95% CI = -10.96, -2.81), suggesting the existence of a "dose-response" effect. The birth outcomes in mildly depressed pregnant women were similar to those of nondepressed women.

CONCLUSION

Anxiety symptoms, beyond a categorical diagnosis, are associated with low birth weight and should be recognized and properly treated during pregnancy.

Anxiety, depression, and cardiac outcomes after a first diagnosis of acute coronary syndrome

OBJECTIVE

Depression is an established risk factor for acute coronary syndrome (ACS), with an impact on cardiac prognosis; nonetheless, the literature disagrees on the role played by anxiety. No study has evaluated this relationship in a cardiac population with no history of depression and after their first diagnosis of ACS. The aim of this study is to explore these associations without the confounding role of long-lasting heart disease or psychiatric illnesses.

METHOD

Two hundred sixty-six patients with no history of depression completed the Hospital Anxiety and Depression Scale and the Primary Care Evaluation of Mental Disorder at baseline and at 1, 2, 4, 6, 9, 12, and 24 months follow-up after their first diagnosis of ACS. During the follow-up period, we collected information regarding the major adverse cardiac events.

RESULTS

Developing a first-ever depressive episode, in a proportional hazard model, was associated with almost 3 times the risk of a recurrent cardiac event (odds ratio = 2.590, 95% confidence interval [CI] [1.321, 5.078], p = .006). Furthermore, a moderation analysis revealed that increasing levels of baseline anxiety had opposing effects on cardiac outcomes, being protective only in those who did not develop incident depression (B = -0.0824, 95% CI [-0.164, -0.005], p = .048). No dose-response effect between depressive or anxious symptoms and cardiac outcomes emerged.

CONCLUSION

Our results confirm the detrimental effect of depression on cardiac prognosis in a selected population and suggest that anxiety after the first diagnosis of ACS might have different roles depending on the illness' course. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Delusional disorder: The role of personality and emotions on delusional ideation

The relationship between personality and Delusional Disorder in still debated. The present study aimed to evaluate the role of personality features and emotional dispositions on the proneness to delusional beliefs, through the lens of a dimensional approach. 91 outpatients were administered the Structured Interview for DSM-IV Personality Disorders, the Pathological Narcissism Inventory, the Positive and Negative Affect Schedule and the Peters et al. Delusions Inventory. Delusion proneness was positively related to the "Hiding the Self" domain of narcissistic vulnerability and to paranoid traits and negatively related to "Positive Affect". Paranoid traits and "Hiding the Self" significantly interacted in influencing delusion ideation. These data suggest that proneness to delusion depends, at least in part, on a complex interplay between specific emotional and paranoid dispositions within personality.

Spontaneous Deep Femoral Artery False Aneurysm Simulating a Neoplasm: A Rare Case and Literature Review

A 70-year-old woman presented to our attention with a painless pulsating mass at the level of the upper left thigh without any previous history of trauma, arterial surgery, or puncture of the femoral artery. Duplex ultrasound showed a nodular angiomatous-like formation with deep venous compression; computed tomographic angiography and magnetic resonance imaging reported the presence of capsulated lesion vascularized by muscular branch of deep femoral artery (DFA). The patient underwent surgical excision of a very rare thrombized DFA branch false aneurysm. Spontaneous DFA false aneurysm, although rare, will be considered in absence of trauma or vascular catheterization or previous aneurysmal rupture.

Increased oxytocin levels among abstinent heroin addicts: Association with aggressiveness, psychiatric symptoms and perceived childhood neglect

A disruption of the oxytocin system seems to affect a variety of brain functions including emotions, mood and social behavior possibly underlying severe social deficits and susceptibility for substance use and mental health disorders. Early life adversity, such as insecure attachment in childhood, has been suggested to influence oxytocin tone contributing to a condition of neurobiological vulnerability. Aim of the present study was to investigate oxytocin serum levels in abstinent heroin addicted patients, in comparison with healthy controls, and the possible correlation with co-occurring psychiatric symptoms, aggressiveness and perception of parental neglect. Eighteen (18) abstinent patients, affected by heroin use disorders, and 18 control subjects, who never used drugs or abused alcohol, were included in the study and submitted to 1) collection of a blood sample for oxytocin assay, 2) Symptoms Check List 90 for psychiatric symptoms evaluation 3) Buss Durkee Hostility Inventory to measure aggressiveness 4) Child Experience of Care and Abuse-Questionnaire to retrospectively test the perception of parental neglect. Heroin exposure extent and heroin dosages were also recorded. Oxytocin serum levels were unexpectedly significantly higher among abstinent patients affected by heroin use disorders and positively correlated with psychiatric symptoms, aggressiveness and mother neglect scores. No correlation was evidenced between oxytocin and heroin exposure extent or dosages. Our findings appear to contradict the simplistic view of oxytocin as a pro-social hormone and confirm previous evidence concerning the peptide levels direct association with aggressive behavior and mood disorders. Considering a more complex mechanism, oxytocin would increase the sensitivity to social salience cues related to contextual or inter-individual factors, promoting pro-sociality in "safe" conditions and, in contrast, inducing more defensive and "anti-social" emotions and behaviors when the social cues are interpreted as "unsafe". This latter condition is often characterizing the clinical history of addicted patients.

Obsessive-compulsive symptoms interact with disorganization in influencing social functioning in schizophrenia

OBJECTIVE

Recent research has suggested a dual impact of obsessive-compulsive dimension on functioning in schizophrenia with a gradual transition from an improving to a worsening effect depending on obsessive-compulsive symptoms (OCS) severity (from mild to moderate-severe). Aim of the present study was to investigate whether this varying effect of OCS on functioning might be mediated or moderated by schizophrenia symptom dimensions or occur independently.

METHOD

Seventy-five patients affected by schizophrenia were administered the Structured Clinical Interview for DSM-IV Disorders, the Positive and Negative Syndrome Scale, the Yale-Brown Obsessive-Compulsive Scale and the Social and Occupational Functioning Assessment. The sample was divided into two groups according to the severity of OCS (absent/mild and moderate/high OCS group).

RESULTS

In both groups, the effect of OCS on functioning was not mediated by their effect on positive, negative or disorganization symptoms. Conversely, a significant interaction between OCS and disorganization dimension was found: the dual effect of OCS on functioning occurred only among patients with low disorganization symptoms while it was no more apparent at high levels of disorganization.

CONCLUSION

Data suggest that in patients with schizophrenia, functioning at least in part depends on the interaction between disorganization and OCS.

Obsessive-compulsive symptom severity in schizophrenia: a Janus Bifrons effect on functioning

The impact of obsessive-compulsive symptoms on functioning in schizophrenia is still debated. This study investigated the relationship between OC symptoms and functioning along a severity gradient of obsessive-compulsive dimension. Sixty patients affected by schizophrenia completed the SCID-IV, the Positive and Negative Syndrome Scale, the Yale-Brown Obsessive-Compulsive Scale and the Social and Occupational Functioning Assessment Scale. The relationship between functioning and obsessive-compulsive dimension was described by a reverse U-shaped curve; functioning was positively related to the presence of mild obsessive-compulsive symptoms and inversely related to moderate and severe symptoms, after controlling for the severity of positive, negative, disorganization and general psychopathological symptoms. The role of obsessive-compulsive symptoms on social functioning in schizophrenia occurs along a severity continuum with a gradual transition from a positive correlation (from absent to mild symptoms) to an inverse correlation (for symptoms ranging from moderate to severe) and independently from schizophrenia symptom dimensions.

Clinical management of perinatal anxiety disorders: A systematic review

BACKGROUND

In the last few decades, there has been a growing interest in anxiety disorders (AnxD) in the perinatal period. Although AnxD are diagnosed in 4-39% of pregnant women and in up to 16% of women after delivery, evidence on their clinical management is limited.

METHODS

A systematic review was conducted on pharmacological and non-pharmacological treatment of AnxD in the perinatal period. Relevant papers published from January 1st 2015 were identified searching the electronic databases MEDLINE, Embase, PsycINFO and the Cochrane Library.

RESULTS

18 articles met inclusion criteria. Selected studies supported the use of cognitive-behavioural therapy (CBT) for obsessive-compulsive disorder (OCD), panic disorder (PD) and specific phobia both in pregnancy and postpartum. Selective serotonin reuptake inhibitors (SSRIs) led to significant OCD and PD improvement both in pregnancy and postpartum with no side effects for the babies. In the largest clinical sample to date, 65% of postpartum patients who entered the open-label trial of fluvoxamine (up to 300mg/day) experienced a 30% or greater decrease in the total score of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). During pregnancy, SSRIs and tricyclic antidepressants (TCAs) led to remission of panic symptoms and healthy outcomes for the babies.

LIMITATIONS

Study design, mostly case reports, and enrolment of subjects mainly from outpatient specialty units might have limited community-wide generalisability.

CONCLUSIONS

Keeping in mind the scantiness and heterogeneity of the available literature, the best interpretation of the available evidence appears to be that CBT should be the first treatment offered to pregnant and breastfeeding women with AnxD. However SSRIs can represent a first line treatment strategy, and not exclusively in cases where AnxD is refractory to CBT.

Anhedonia in schizophrenia: The role of subjective experiences

BACKGROUND

High levels of anhedonia have been found in patients with schizophrenia; specifically they report higher levels of social anhedonia rather than physical anhedonia, and further, in the anticipatory rather than consummatory facets of pleasure. Nonetheless, contrasting results emerged regarding the underlying mechanisms of this deficit. Basic Symptoms (BS) disturb subjective experiences present for most of the illness' course; this impacts patients' daily lives leading to a loss of the ability to organize the experience of the self and the world in a fluid and automatic way. Considering the role played by negative emotions in the subjective evaluation of anhedonia, the aim of the study is to clarify the role of BS in the assessment of anhedonia in a sample of patients with schizophrenia (n=53) compared with healthy controls (n=46).

METHODS

Participants completed a self-administered trait questionnaire evaluating social anhedonia (Revised-Social Anhedonia Scale), physical anhedonia (Physical Anhedonia Scale), and the consummatory and anticipatory pleasure experiences (Temporal Experience of Pleasure Scale). BS were evaluated with the Frankfurter Beschwerde-Frageboden (FBF) whereas psychopathology was assessed with the Positive and Negative Syndromes Scale.

RESULTS

Patients scored higher than healthy controls in social, physical and anticipatory anhedonia, but not in consummatory anhedonia and these relationships were mediated by the FBF. Basic Symptoms of Memory, Overstimulation and Lack of Automatism were related to some facets of anhedonia, independently from depressive symptoms.

CONCLUSIONS

We hypothesize that a subjective cognitive deficit and a reduced ability in information processing, could prevent patients from retaining a positive experience from past pleasant activities. Therefore the lack of pleasure would be, at least in part, related to an avoidance of potentially stressful new scenarios.
