Abstract
OBJECTIVE Anti-COVID-19 vaccines were mainly associated with non-serious adverse events (AEs), whose prevalence was reported to be up to 70% in healthcare workers (HCWs). This may lead to sick leave requests, but this impact has never been quantified. This study aimed to investigate the absence from work among HCWs following anti-COVID-19 vaccination. Its association with age and previous COVID-19 infection was also assessed. PATIENTS AND METHODS This is a retrospective observational cross-sectional study on administrative data about sick leave requests after anti-COVID-19 vaccination. All the HCWs employed at the Niguarda Hospital (Milan, Italy) who received the vaccine from December 27, 2020 to February 28, 2021 were included. RESULTS In total, 4,088 HCWs received the first dose of the vaccine and 4,043 completed the vaccination cycle. After the first injection, 1.6% of HCWs requested sick leave, while after the second injection, the number of requests significantly increased (+6.1%, p<0.001). A significant increase in sick leave was detected for those who have had SARS-CoV-2 infection after the first injection (+2.3%, p<0.001). After the second dose, a significant increase in sick leave was observed in the 20-30-year-old group compared to >30 years (+3.6%, p=0.017), if HCWs without a history of SARS-CoV-2 infection were considered. CONCLUSIONS The requests for sick leave among HCWs following the anti-COVID-19 vaccine were limited and higher after the second injection. This may help the management of the human resources when the large-scale administration of the anti-COVID-19 vaccines will involve other categories of workers.

Abstract
SummaryThe authors investigated the comorbidity between obsessive-compulsive disorder (OCD) and other psychiatric disorders in a group of 154 outpatients. The influence of an associate major depressive disorder (MDD) on the outcome of treatment with clomipramine was examined in a subgroup of 52 patients. The results showed that MDD was the most frequent disorder associated with OCD (almost 20% of the patients), followed by generalized anxiety and panic disorder. The co-presence of depression delayed the effect of clomipramine.

Abstract
BACKGROUND AND OBJECTIVES A role for the protein that mediates the rate-limiting step of steroidogenesis, the 18 kDa Translocator Protein (TSPO), has been suggested in the pathophysiology of Adult Separation Anxiety Disorder (ASAD). It has been shown that ASAD patients have 1) low TSPO expression levels and 2) a high frequency of the allele that substitutes Ala with Thr at position 147 of TSPO. The Thr147 ASAD-associated allele has been recently related with a low pregnenolone production. The aim of the present work was to evaluate the relationship between TSPO expression levels and Ala147Thr single nucleotide polymorphism (SNP), which are the two TSPO biological parameters that we have previously examined separately. A further aim was to confirm the genetic association of Ala147Thr SNP with ASAD in an extended case-control sample and to investigate whether this SNP was related to an anxious attachment style that is thought to be connected to ASAD. METHODS TSPO expression levels were compared among patients with ASAD (n=26), without ASAD (n=26) and control samples (n=10) stratified into the two genotype groups: those with the Ala147 genotype (named "normal pregnenolone production") and those with the Thr147 genotype (named "reduced pregnenolone production"). The case-control genetic study included patients with (n=87) or without (n=101) ASAD and 236 controls. In the patient group, the association between the Ala147Thr SNP and an anxious attachment style was analysed by stepwise logistic regression analysis. RESULTS The genotype with the lowest TSPO expression levels was the "normal pregnenolone production" genotype in the ASAD group. The genetic Ala147Thr SNP confirmed an excess of the Thr147 allele in ASAD patients. Stepwise logistic regression analysis did not show an association with an anxious attachment style. CONCLUSIONS ASAD individuals who expressed normal TSPO levels exhibited the "reduced pregnenolone production" genotype. In contrast, the ASAD individuals with the "normal pregnenolone production" genotype expressed low TSPO levels. It is possible that low TSPO expression levels could compromise normal pregnenolone production. Such evidence may have therapeutic implications because it has been documented that drugs targeting TSPO increased pregnenolone production and have anxiolytic effects.

Abstract
BACKGROUND Efficacy of treatments for panic disorder is well established, but not all patients respond. Adult separation anxiety has been found to predict poorer response to CBT, but its effect on response to medication has not been previously explored. STUDY AIM The aim of this study is to investigate if panic-agoraphobic spectrum factors, including 'separation anxiety' factor predict treatment outcome in patients with panic disorder. STUDY SAMPLE Participants who met criteria for PD (n=57) completed baseline assessment and 12 months follow-up. Patients were administered the Panic Agoraphobic Spectrum Self-Report (PAS-SR, Lifetime and Last-Month Versions), and the Panic Disorder Severity Scale (PDSS). We examined patients who met the following criteria at baseline: 1) PDSS total score>7; 2) no current Axis I comorbidity with major depression; 3) no lifetime or current bipolar disorder. All patients were treated with evidence-based psychopharmacological treatment for panic disorder during the 12-month observation period. RESULTS Twenty eight patients (48.1%) achieved remission during the follow-up period. In a logistic regression model, controlling for baseline severity, gender and age, only the last-month PAS-SR 'separation anxiety' factor was associated with a lower likelihood of remission. CONCLUSIONS Signs and symptoms of separation anxiety in adulthood, as assessed with the PAS-SR Last Month version, are predictors of poor treatment outcome in patients with PD. We submit that the assessment of panic-agoraphobic spectrum features, including adult separation anxiety, should become routine of clinical assessment of patients with PD. It is likely that a better psychopathological characterization of patients may inform treatment selection, and result in better treatment outcome.

Abstract
BACKGROUND Studies investigating neurocognitive impairment in subjects with eating disorders (EDs) have reported heterogeneous patterns of impairment and, in some instances, no dysfunction. The present study aimed to define the pattern of neurocognitive impairment in a large sample of bulimia nervosa (BN) patients and to demonstrate that neuroendocrine, personality and clinical characteristics influence neurocognitive performance in BN. METHOD Attention/immediate memory, set shifting, perseveration, conditional and implicit learning were evaluated in 83 untreated female patients with BN and 77 healthy controls (HC). Cortisol and 17β-estradiol plasma levels were assessed. Cloninger's Temperament and Character Inventory - Revised (TCI-R), the Bulimic Investigation Test Edinburgh (BITE) and the Montgomery-Asberg Depression Rating Scale (MADRS) were administered. RESULTS No impairment of cognitive performance was found in subjects with BN compared with HC. Cortisol and 'Self-directedness' were associated with better performance on conditional learning whereas 17β-estradiol had a negative influence on this domain; 'Reward dependence' was associated with worse performance on implicit learning; and depressive symptomatology influenced performance on the Wisconsin Card Sorting Test (WCST) negatively. CONCLUSIONS No cognitive impairment was found in untreated patients with BN. Neuroendocrine, personality and clinical variables do influence neurocognitive functioning and might explain discrepancies in literature findings.

Abstract
OBJECTIVES This study aimed to ascertain predictors of nonresponse to electroconvulsive therapy (ECT) in a large sample of major depressive patients resistant to pharmacologic treatment. METHODS A total of 208 depressive patients (31 with major depression [UP], 101 with bipolar disorder II [BP II], and 76 with bipolar disorder I [BP I] according to DSM-IV criteria) were included in the study and treated with bilateral ECT on a twice-a-week schedule. The patients were assessed before (baseline) and a week after the ECT course (final score) using the Hamilton Rating Scale for Depression-17 items (HAM-D-17), the Young Mania Rating Scale (YMRS), the Brief Psychiatric Rating Scale (BPRS), and the Clinical Global Improvement (CGI). Responders were defined as those patients with a reduction of at least 50% in HAM-D-17 score and a rating of 2 ("much improved") or 1 ("very much improved") in the CGI-Improvement subscale. RESULTS At the end of the ECT course, 152 patients (64%) were classified as responders and 56 patients (36%) were classified as nonresponders. On backward stepwise logistic regression, bipolar subtype (odds ratio [OR]=17.85; 95% confidence level [CL]=1.786-178.407), higher mean baseline YMRS scores (OR=1.094; 95% CL=1.025-1.166), lower mean baseline HAM-D-17 scores (OR=0.928; 95% CL=0.860-1.002), and length of current episode (OR=1.047; 95% CL=1.009-1.086) were identified as statistically significant predictors of nonresponse. CONCLUSIONS ECT was an effective treatment for approximately two-thirds of the patients with medication-resistant depression who were included in this study. ECT nonresponse was associated with bipolar subtype, presence of manic symptoms during depression, slightly less severe depressive symptomatology, and protracted duration of the episode.

Abstract
BACKGROUND The recognition and assessment of psychomotor retardation may have implications for better definition of the clinical phenotypes of depression. The aim of this study was to assess the clinical correlates of psychomotor retardation endorsed at any time during the patients' lifetime (LPR). METHODS The study sample included 291 patients with non-psychotic major depressive disorder (MDD) participating in the clinical trial, "Depression: The Search for Treatment-Relevant Phenotypes." Psychomotor retardation was measured using a factor derived from the Mood Spectrum Self-Report (MOODS-SR) assessment. Using a pre-defined cut-off score on the lifetime psychomotor retardation (LPR) factor of the MOODS-SR, participants were classified into high and low scorers. Logistic regression analysis was used to evaluate the relationship between LPR and subthreshold bipolarity. RESULTS Compared to low scorers, participants with high scores on the LPR factor had greater severity of depression and more bipolarity indicators. CONCLUSIONS The MOODS-SR appears to be helpful to identify clinical phenotypes of unipolar depression and to highlight the usefulness of a lifetime approach to the assessment of psychopathology in the characterisation of patients with unipolar depression.

Abstract
BACKGROUND Although many studies suggest that, on average, depression-specific psychotherapy and antidepressant pharmacotherapy are efficacious, we know relatively little about which patients are more likely to respond to one versus the other. We sought to determine whether measures of spectrum psychopathology are useful in deciding which patients with unipolar depression should receive pharmacotherapy versus depression-specific psychotherapy. METHOD A total of 318 adult out-patients with major depression were randomly assigned to escitalopram pharmacotherapy or interpersonal psychotherapy (IPT) at academic medical centers at Pittsburgh, Pennsylvania and Pisa, Italy. Our main focus was on predictors and moderators of time to remission on monotherapy at 12 weeks. RESULTS Participants with higher scores on the need for medical reassurance factor of the Panic-Agoraphobic Spectrum Self-Report (PAS-SR) had more rapid remission with IPT and those with lower scores on the psychomotor activation factor of the Mood Spectrum Self-Report (MOODS-SR) experienced more rapid remission with selective serotonin reuptake inhibitor (SSRI) pharmacotherapy. Non-specific predictors of longer time to remission with monotherapy included several panic spectrum and mood spectrum factors and the Social Phobia Spectrum (SHY) total score. Higher baseline scores on the 17- and 25-item Hamilton Depression Rating Scales (HAMD-17 and HAMD-25) and the Work and Social Adjustment Scale (WSAS) also predicted a longer time to remission, whereas being married predicted a shorter time to remission. CONCLUSIONS This exploratory study identified several non-specific predictors but few moderators of psychotherapy versus pharmacotherapy outcome. It offers useful indicators of the characteristics of patients that are generally difficult to treat, but only limited guidance as to who benefits from IPT versus SSRI pharmacotherapy.

Abstract
BACKGROUND Although the role of anxiety disorders on the development of Post-partum Depression (PPD) have already been studied in literature, that of individual anxiety disorders has not received specific attention. The aim of this study is to investigate the role of Panic Disorder (PD) and family history for PD as risk factors for PPD. METHODS Six hundred women were recruited in a prospective, observational study at the 3rd month of pregnancy and followed up until the 6th month after delivery. At baseline, risk factors for PPD, Axis-I disorders and family history for psychiatric disorders were assessed. We investigated minor and major depression (mMD) occurred at 1st, 3rd and 6th months post-partum. Logistic regression models were used to estimate the association between PD, family history for PD and PPD. RESULTS Forty women had mMD in the post-partum. PD during pregnancy (RR=4.25; 95%CI:1.48-12.19), a history of PD (RR 2.47; 95%CI:1.11-5.49) and family history for PD (RR=2.1; 95%CI:1.06-4.4) predicted PPD after adjusting for lifetime depression and risk factors for PPD. LIMITATIONS The response rate is moderately low, but it is similar to other studies. The drop out rate is slightly high, however the 600 women who completed the 6th month follow-up did not differ from the presence of PD at baseline. CONCLUSIONS PD is an independent risk factor for PPD, underscoring need to assess PD symptoms during pregnancy. Furthermore, PD represents an important risk factor for the development of PPD and should be routinely screened in order to develop specific preventive interventions.

Abstract
The objective was to determine the prevalence of the metabolic syndrome (MS) in patients with systemic lupus erythematosus (SLE) in Argentina, to assess the factors associated to it, and to compare the results with a control group with non-inflammatory disorders. The study included 147 patients with SLE and 119 controls. MS was defined according to criteria by the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) Scientific Statement. Demographic characteristics, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) and Systemic Lupus International Collaborating Clinics/ACR Damage Index (SDI) were assessed as well as administration, maximum dose and cumulative dose of prednisone and hydroxychloroquine (HCQ). MS prevalence was 28.6% (CI 95%: 21.4-36.6) in patients with SLE and 16% in controls (P = 0.0019). Patients with SLE presented higher arterial hypertension frequency compared with controls (43 vs 25%, P = 0.007). When comparing lupus patients with MS (n = 41) and without MS (n = 106), no significant differences were observed regarding duration of the disease, SLEDAI or cumulative prednisone dose. Cumulative damage was associated independently with MS (OR 1.98; P = 0.021), whereas HCQ use was found to be protective (OR 0.13; P = 0.015). Patients with lupus presented higher MS prevalence than controls with non-inflammatory disorders, and occurrence of arterial hypertension was also higher. MS was associated with cumulative damage; the use of HCQ showed to be protective against presence of MS.

Abstract
OBJECTIVES A significant body of evidence indicates the efficacy of electroconvulsive therapy (ECT) in unipolar depression but mixed results have been reported in bipolar depression. We explored difference of response to ECT in unipolar (UP), bipolar I (BP I) and bipolar II (BP II) depression, in a sample of patients resistant to pharmacological treatment. METHODS One hundred and thirty depressive patients (17 with Major Depression (UP), 67 with bipolar disorder II (BP II) and 46 with bipolar disorder I (BP I) according to DSM-IV criteria) were included in the study and treated with bilateral ECT, on a twice-a-week schedule. The patients were assessed before (baseline) and a week after the ECT course (final score), using the Hamilton Rating Scale for Depression (HAM-D), Young Mania Rating Scale (YMRS), Brief Psychiatric Rating Scale (BPRS) and the Clinical Global Improvement (CGI). RESULTS The three groups (UP, BP II, BP I) showed a significant improvement after the ECT course. Global response rate (CGI<2) was 94.1% for UP, 79.1% for BP II and 67.4% for BP I. Concerning depressive symptomatology, the remission rate (HAM-D <8) was respectively 70.5 for UP, 56.7% for BP II and 65.3% for BP I. The best results were achieved by UP patients, while BP I group showed the worst results with a lower remission rate and higher scores in YMRS and BPRS psychotic cluster at the final evaluation. CONCLUSION ECT turns out to be a viable option for the treatment of both unipolar and bipolar depressive patients resistant to pharmacological treatment. Nevertheless, while the UP group showed the best response and clinical outcomes, the BP I patients tended to exhibit residual manic and psychotic symptomatology.

Abstract
Clinical features and treatment outcome were compared in depressed outpatients with and without a history of emotional and physical abuse (EPA), including childhood maltreatment. Patients were initially randomized to IPT or SSRI and then augmented with the second treatment if they did not remit with monotherapy. Assessments included the SCID-I, the SCID-II for DSM-IV diagnoses, the HRSD, the QIDS and the Mood Spectrum Self-Report (MOODS-SR). Seventy-eight (25%) patients reported a history of EPA; 60 (76.9%) were women. Patients with a history of EPA did not differ from those without on HRSD scores at baseline, but showed an earlier age at onset of depression and a longer duration of illness. The two groups differed on several mood spectrum factors, namely: 'depressivemood' (15.6+/-4.9 vs. 13.5+/-5.4; p<0.004), 'psychomotorretardation' (11.7+/-4.5 vs. 9.6+/-4.7; p<0.001), 'drugandillness-relateddepression' (1.3+/-1.3 vs. 0.6+/-1.0; p<0.0001), and 'neurovegetativesymptoms' (8.3+/-2.6 vs. 6.9+/-2.9; p<0.0001). Patients with EPA had also a significantly longer time to remission (89 vs. 67days, log-rank test, p=0.035). The need for augmentation treatment was significantly more frequent among patients with EPA than in those without. The present study suggests that patients with a history of EPA show a subtype of depression characterized by poor treatment response and more severe neurovegetative and psychomotor symptoms.

Abstract
The heterogeneity of the clinical presentation of panic disorder (PD) has prompted researchers to describe different subtypes of PD, on the basis of the observed predominant symptoms constellation. Starting from a dimensional approach to panic disorder, an instrument to assess lifetime panic-agoraphobic spectrum (PAS) available in interview or self-report form (SCI-PAS, PAS-SR) was developed which proved to have sound psychometric properties and the ability to predict delayed response to treatment in patients with mood disorders. However, the structure of the instrument was defined a priori and an examination of its empirical structure is still lacking. Aim of the present report is to analyse the factor structure of the PAS taking advantage of a large database of subjects with panic disorders (N=630) assessed in the framework of different studies. Using a classical exploratory factor analysis based on a tetrachoric correlation matrix and oblique rotation, 10 factors were extracted, accounting overall for 66.3% of the variance of the questionnaire: panic symptoms, agoraphobia, claustrophobia, separation anxiety, fear of losing control, drug sensitivity and phobia, medical reassurance, rescue object, loss sensitivity, reassurance from family members. The first two factors comprise the DSM-IV criteria for panic disorder and agoraphobia. The other factors had received limited empirical support to date. We submit that these symptoms profiles might be clinically relevant for tailoring drug treatments or psychotherapeutic approaches to specific needs. Future perspectives might include the use of these factors to select homogeneous subgroups of patients for brain-imaging studies and to contribute to elucidating the causes and pathophysiology of panic disorder at molecular level.

Abstract
This study explores the psychometric properties of the Spanish adaptation of the Mood Spectrum Self-Report (MOODS-SR), an instrument designed to assess a broad range of manifestations of mood psychopathology. A total of 71 Spanish subjects participated: 49 outpatients who met criteria for a mood disorder or generalized anxiety disorder, and 22 normal controls. The instrument proved to have good internal consistency and test-retest reliability. Significant positive correlations were found between the depressive subdomains of the questionnaire and the Beck Depression Inventory, as well as between the manic-hypomanic subdomains and the Clinician-Administered Rating Scale for Mania. Clinical subjects displayed higher mean scores than normal subjects in all domains, and patients with bipolar disorder displayed higher scores than patients with unipolar disorder in the Manic component, particularly in the Energy and the Cognition subdomains. Differences between patients with generalized anxiety and mood disorders were small. The former, however, did not differ from normal controls in several subdomains, whereas patients with mood disorders did.

Abstract
INTRODUCTION Given the controversial data concerning the role of the serotonin (5-HT) transporter in psychosis, our study was aimed to investigate this structure by means of the measurements of the re-uptake kinetics and of the protein density, in both platelets and lymphocytes of 25 out- and inpatients with different psychotic disorders. METHODS Diagnoses, according to DSM-IV criteria, were bipolar 1 disorders with mood incongruent psychotic features (14), mixed states (7) and schizophrenia (4). Twenty-five matched healthy subjects were also selected as the control group. Platelet and lymphocyte membranes were prepared according to standardized protocols, as were the [3H]5HT re-uptake and [3H]paroxetine ([3H]Par) binding. RESULTS The results of this study showed a decreased density of the [3H]Par binding sites coupled with a reduced velocity of [3H]5-HT re-uptake in both platelets and lymphocytes of psychotic patients, as compared with healthy control subjects. CONCLUSION These findings would suggest a general abnormality of the 5-HT system in psychotic patients, probably not confined only to the brain.

Abstract
OBJECTIVE To investigate the relationship between lifetime mood and psychotic spectrum features in patients with borderline personality disorder (BPD). METHOD The study sample consisted of BPD patients with (n=39, BPD-M) or without (n=21, BPD-no M) lifetime mood disorders. The diagnostic assessment was conducted with the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). The diagnosis of BPD was made clinically and then confirmed by Gunderson's diagnostic interview for borderlines. Subjects were also administered the Structured Clinical Interview for Psychotic Spectrum (SCI-PSY) and the Mood Spectrum self-report questionnaire (MOODS-SR). RESULTS BPD-M had significantly higher scores than BPD-no M on the 'lifetime' mood spectrum subdomains 'depressive mood' and 'depressive cognition'. The two groups did not differ on the scores of psychotic spectrum except for higher 'hypertrophic self-esteem' scores in BPD-no M. In BPD-no M both the depressive and the manic-hypomanic component of mood spectrum were significantly correlated with the 'delusion' subdomain of the psychotic spectrum. The depressive component was correlated with 'depersonalization/derealization' and the manic-hypomanic component was correlated with 'hypertrophic self-esteem'. In BPD-M, the manic-hypomanic component of mood spectrum was correlated with different subdomains of the psychotic spectrum: 'hypertrophic self-esteem', 'self-reference', 'interpretive attitude', 'anger/overreactivity, 'unusual and odd thoughts', 'illusions', 'delusions', 'hallucinations' and 'catatonia'. The depressive component of mood spectrum was 'uncorrelated' with the subdomains of the psychotic spectrum. CONCLUSIONS Our data support the hypothesis that 'lifetime' manic-hypomanic mood dysregulations are correlated with psychotic spectrum features in borderline patients. The assessment of these spectrum features in borderline patients may be useful to inform treatment choices.

Abstract
This study evaluates the validity and the reliability of a new instrument developed to assess the psychotic spectrum: the Structured Clinical Interview for the Psychotic Spectrum (SCI-PSY). The instrument is based on a spectrum model that emphasizes soft signs, low-grade symptoms, subthreshold syndromes, as well as temperamental and personality traits comprising the clinical and subsyndromal psychotic manifestations. The items of the interview include, in addition to a subset of the DSM-IV criteria for psychotic syndromes, a number of features derived from clinical experience and from a review of the phenomenological descriptions of psychoses. Study participants were enrolled at 11 Italian Departments of Psychiatry located at 9 sites and included 77 consecutive patients with schizophrenia or schizoaffective disorder, 66 with borderline personality disorder, 59 with psychotic mood disorders, 98 with non-psychotic mood disorders and 57 with panic disorder. A comparison group of 102 unselected controls was enrolled at the same sites. The SCI-PSY significantly discriminated subjects with any psychiatric diagnosis from controls and subjects with from those without psychotic disorders. The hypothesized structure of the instrument was confirmed empirically.

Abstract
Obsessive-compulsive disorder (OCD) is a common psychiatric condition during childhood and adolescence, which continues to be underestimated and undertreated. For these reasons, it constitutes a primary cause of major disabilities in those ages and, sometimes, of permanent impairments later on. In these last few years, childhood and adolescence OCD has attracted an increasing focus which has promoted a deeper awareness of this illness, a better recognition with earlier interventions, as well as the set-up of more tailored and specific strategies, including psychotropic drugs. The aim of this paper is to present a critical review of paediatric OCD, with a special attention towards the most compelling reports available up to now and towards the most interesting areas for future research.

Abstract
In these last years, emotions and feelings, such as attachment, couple and parental bonding and even love, typical of higher mammals, neglected for centuries by experimental sciences, have become the topic of extensive neuroscientific research in order to elucidate their biological mechanisms. Several observations have highlighted the role of monoamines and of neuropeptides, in particular oxytocin, vasopressin and opioids, but this is only the beginning of the story. Love, the most typical human feeling, can be viewed as a dynamic process that represents the result of different components probably subserved by distinct neural substrates at different times. As such, some steps can be identified, in particular its beginning, which is the process of attraction, followed by the attachment process that, in some cases, can last forever. This paper will make some general speculations on the attraction process, in the light of the experience of the Authors.

Abstract
This paper reports on the acceptability, reliability and validity of the Structured Clinical Interview for the Spectrum of Substance Use (SCI-SUBS), a new instrument exploring the interactive pathway between substance abuse and psychiatric disorders. Psychiatric outpatients with (n = 21) and without (n = 32) substance abuse comorbidity according to the DSM-IV, non-psychiatric subjects with opioid dependence (OD, n = 14) and normal controls (n = 33) were assessed with the SCI-SUBS. The presence or absence of psychiatric disorders was determined with the Structured Clinical Interview for DSM IV (SCID). The SCI-SUBS was well accepted by participants. The internal consistency of the domains was satisfactory (between 0.64 and 0.93). Domain scores of OD subjects were significantly higher than those of controls and of psychiatric patients without substance abuse. The cut-off point on the SCI-SUBS total score at which there was optimal discrimination between the presence and the absence of a DSM-IV diagnosis of substance abuse was 45. The pilot version of the SCI-SUBS has satisfactory internal consistency and construct validity.

Abstract
The efficacy of amisulpride in depressive disorders has been demonstrated in dysthymia and in double depression. Limited data are available in major depression. A randomized, double-blind, parallel group, multicentre study was set up to compare the efficacy and tolerability of amisulpride (50 mg o.d.) and paroxetine (20 mg o.d.) for 8 weeks in 272 patients with major depression (DSM-IV and baseline Hamilton Depression Rating Scale (HAMD) score > or = 18). The study was designed as a non-inferiority trial based on the proportion of responders (> or = 50% decrease in HAMD total score) at end-point, with a maximal allowable difference of 15%; secondary end-points included HAMD total and cluster scores, Montgomery and Asberg Depression Rating Scale score and responders rates and Clinical Global Impression improvement. The tolerability evaluation was based on incidence of adverse events and routine laboratory tests. The results did not disclose statistically significant differences between treatments, although the hypothesis of an efficacy difference between the two treatments within the set limit at day 56 could not be accepted. The issue of non-inferiority trials is discussed.

Abstract
In frog skin, tachykinins stimulate ion transport by interaction with NK1-like receptors. The structural requirements of the peptide are the presence of the C-terminal sequence Phe-X-Gly-Leu-Met-NH(2) and at least one Pro residue in the N-terminal sequence. In this paper, we demonstrate that the C-terminal amino acid must be amidated but it can be different from Met, and that the sequence cannot be longer or shorter than 11-12 amino acids. Unexpectedly, Ranamargarin (14 amino acids, no Pro residue) increased the short circuit current value by 48 +/- 0.3%. On the basis of considerable experimental evidence, we suggest that Ranamargarin interacts with a receptor different from those of other tachykinins.

Abstract
BACKGROUND Abnormalities in different parameters of the norepinephrine system have been widely described in major depression. The presence of alpha(2)-adrenoreceptors in blood platelets, similar to those in the brain, prompted us to evaluate them in depressed patients, as compared with healthy controls. METHODS Fifteen outpatients affected by major depression, according to DSM IV criteria, and 15 comparable healthy control subjects, were included in the study. The alpha(2)-adrenoreceptors were measured by means of the specific binding of [(3)H]rauwolscine, a highly selective antagonist for this receptor subtype. The severity of depression was assessed by means of the Hamilton Rating Scale for Depression (HRSD). RESULTS The results did not show any difference in [(3)H]rauwolscine binding parameters (B(max) and K(d)) between patients and controls. However, in the patients, a significant and positive correlation between B(max), which measures the density of the receptors, and HRSD total score was detected. CONCLUSIONS Therefore, although no change in alpha(2)-adrenoreceptors seems to occur in major depression, the density of these receptors would seem to be related to the severity of depressive symptoms.

Abstract
A remarkable amount, of water is transported in the gastrointestinal (GI) organs to fulfil the secretory and absorptive functions of the GI tract. However, the molecular basis of water movement in the GI epithelial barriers is still poorly known. Important clues about the mechanisms by which water is transported in the GI tract were provided by the recent identification of multiple aquaporin water channels expressed in GI tissues. Here we define the mRNA and protein expression and the cellular and subcellular distribution of aquaporin-8 (AQP8) in the rat GI tract. By semi-quantitative RT-PCR the AQP8 mRNA was detected in duodenum, proximal jejunum, proximal colon, rectum, pancreas and liver and, to a lesser extent, in stomach and distal colon. Immunohistochemistry using affinity-purified antibodies revealed AQP8 staining in the absorptive epithelial cells of duodenum, proximal jejunum, proximal colon and rectum where labeling was largely intracellular and confined to the subapical cytoplasm. Confirming previous results, AQP8 staining was seen at the apical pole of pancreatic acinar cells. Interestingly, both light and immunoelectron microscopy analyses showed AQP8 reactivity in liver where labeling was associated to hepatocyte intracellular vesicles and over the plasma membrane delimiting the bile canaliculi. A complex pattern was observed by immunoblotting with total membranes of the above GI organs incubated with affinity-purified anti-AQP8 antibodies which revealed multiple bands with molecular masses ranging between 28 and 45 kDa. This immunoblotting pattern was not modified after deglycosylation with N-glycosidase F except the 34-kDa band of liver that, as already reported, was partially down-shifted to 28 kDa. No bands were detected after preadsorption of the anti-AQP8 antibodies with the immunizing peptide. The cellular and subcellular distribution of AQP8 suggest physiological roles for this aquaporin in the absorption of water in the intestine and the secretion of bile and pancreatic juice in liver and pancreas, respectively. The large intracellular expression of AQP8 may indicate its recycling between the cytoplasmic compartment and the plasma membrane. The cytoplasmic localization observed may also relate to the involvement of AQP8 in processes of intracellular osmoregulation.

Abstract
Bombesin-like peptides (BLP) and their receptors are widely distributed throughout the intestine and are potential mitogens for gastrointestinal cancers. In this study we characterized the proliferation induced by BLP in the human adenocarcinoma cell line HT-29. The number of HT-29 cells, partially serum deprived (1% fetal bovine serum) for 48 h, was increased after 24 h of stimulation with bombesin, GRP, neuromedin B (NMB) and neuromedin C (NMC) ranging from 0.1 nM up to 1 microM. Reverse transcription polymerase chain reaction studies, revealed the presence of mRNA for NMB and for the GRP preferring receptor (GRP-R). mRNA for GRP, NMB preferring receptor (NMB-R) and bombesin receptor subtype 3 (BRS-3) were not detected. [D-Phe(6)]bombesin-(6-13)methyl ester (A1) and BIM-23127 (A2), are considered as inhibitors of binding to GRP-R and NMB-R, respectively. Surprisingly, A1 and A2 stimulated the proliferation of HT-29 cells. Moreover, in the simultaneous presence of 1 microM A1 and 0.1 microM GRP or 0.1 nM or 0.1 microM bombesin, inhibition of the proliferation was observed. Our data demonstrate that the proliferation induced by BLP in HT-29 cells is due to interaction with the GRP-R.

Abstract
The potency of some tricyclics (imipramine and clomipramine) and selective 5-HT reuptake inhibitors (fluoxetine, paroxetine, and citalopram) in displacing the [(3)H]paroxetine binding to platelet membranes was measured in young and elderly subjects of both sexes. The results showed that the most potent compound in all subjects was paroxetine, followed by clomipramine, citalopram, fluoxetine, and imipramine, with no differences between male and female subjects. All drugs, except paroxetine and clomipramine, showed significantly lower pKi values in the elderly subjects of both sexes. These findings would suggest that although the pharmacological profile of the 5-HT transporter is not modified qualitatively by age, quantitative changes in its affinity do perhaps occur which would justify more careful studies on this topic in order to get optimal dosages of drugs acting at this level.

Abstract
Research to date would suggest the possible involvement of the serotonin (5-HT) system in the pathophysiology of suicide. With this study, we aimed to investigate the platelet 5-HT transporter, by means of the specific binding of tritiated paroxetine ([3H]Par), in a sample of 20 suicide attempters recruited at a first-aid service, as compared with healthy control subjects and psychiatric patients with no current or previous history of suicide attempt. The results, showing a decreased number of [3H]Par binding sites in suicide attempters, would suggest the involvement of the presynaptic 5-HT transporter in self-aggressive behavior.

Abstract
We investigated the presence of mRNA for serotonin receptors of type 2C (5-HT(2C)) in resting lymphocytes by means of RT-PCR and Southern blotting analyses, given their possible role in the pathophysiology of anxiety and eating disorders. At the same time, we explored also the presence of the specific mRNA for 5-HT(5A) receptors, a novel subtype for which still no functional data exist. Healthy subjects and patients with obsessive-compulsive or bipolar disorders were included in the study. The results showed the presence of the specific mRNAs for both 5-HT(2C) and 5-HT(5A) receptors in resting lymphocytes of the three groups of subjects. An additional band was also observed after the amplification of the 5-HT(5A) cDNA in each sample. These findings, while revealing the presence of 5-HT(2C) and 5-HT(5A) receptor mRNAs in an easily available tissue, can be considered preliminary for future quantitative analyses in patients with different psychiatric conditions.

Abstract
Different findings suggest that the serotonin (5-HT) system may be involved in both the regulation of aggression and the pathophysiology of obsessive-compulsive disorder (OCD). Our study aimed to evaluate the aggressive features of a group of OCD patients and to explore possible correlations with a serotonergic marker, namely platelet 5-HT transporter. Psychopathological and biological patterns were compared with those of a group of healthy controls and those of patients with major depression. Twenty-one patients affected by OCD, 21 by depression and 21 healthy controls were included in the study. Aggressive features were measured by means of the Buss and Durkee Hostility Inventory (BDHI). The platelet 5-HT transporter was evaluated by means of the (3)H-paroxetine binding parameters (maximum binding capacity, B(max) and dissociation constant, K(d)). The OCD patients showed a total score on the BDHI not significantly different from that of healthy controls and lower than that of depressed patients. The factor profile was similar in the 3 groups, but higher in the depressed patients. The irritability, resentment, guilt, negativism and suspiciousness factors were significantly more pronounced in depressed patients. Some sex-related difference in single factors were also observed. The B(max) of (3)H-paroxetine binding was lower in OCD patients than in depressives or healthy controls. OCD patients were more similar to healthy controls than to depressed patients with regard to aggressive features measured by means of the BDHI. This suggests that aggression in OCD is a complex phenomenon that probably requires specific instruments of evaluation.

Abstract
BACKGROUND The aim of this study was to investigate the effectiveness of electroconvulsive therapy (ECT) in medication-nonresponsive patients with mixed mania and bipolar depression. METHOD Forty-one patients with mixed mania (DSM-IV diagnosis of bipolar I disorder, most recent episode mixed) and 23 patients with bipolar depression (DSM-IV diagnosis of bipolar I disorder, most recent episode depressed) consecutively assigned to ECT treatment were included in this study. Subjects were evaluated using the Montgomery-Asberg Depression Rating Scale (MADRS), the Brief Psychiatric Rating Scale (BPRS), and the Clinical Global Impressions-Severity of Illness scale (CGI-S). Assessments were carried out the day before starting ECT, 48 hours after completion of the third session (T1), and a week after the last session of ECT (T2). RESULTS Both groups received an equal number of ECT sessions (mean +/- SD = 7.2 +/- 1.7 vs. 7.3 +/- 1.6). In both groups, within-group comparisons showed that there was a significant reduction in CGI-S score (mixed mania, p <.0001 at T1 and T2; bipolar depression, p < .01 at T1, p < .0001 at T2), MADRS total score (both groups, p < .0001 at T1 and T2), BPRS total score (mixed mania, p < .0001 at T1 and T2; bipolar depression, p < .001 at T1, p < .0001 at T2), and BPRS activation factor score (mixed mania, p < .0001 at T1 and T2; bipolar depression, NS at T1, p < .01 at T2). Between-group comparisons revealed that patients with mixed mania showed significantly greater decrease in MADRS score (p < .001) and a greater proportion of responders (CGI-S) than patients with bipolar depression at endpoint (56% [N = 23] vs. 26% [N = 6], p = .02). Patients with mixed mania showed a greater reduction in suicidality, as measured by MADRS score, than patients with bipolar depression (p < .02). CONCLUSION In our study, ECT was associated with a substantial reduction in symptomatology, in both patients with mixed mania and those with bipolar depression. However, the mixed mania group exhibited a more rapid and marked response as well as a greater reduction in suicidal ideation. Response to ECT was not influenced by the presence of delusions.

Abstract
This study aimed to evaluate the effect of citalopram in patients with refractory obsessive-compulsive disorder (OCD) which had not responded to previous antiobsessional treatments. Eighteen patients were selected for this study: they had been suffering from OCD, according to DSM-IV criteria, for at least 2 years and had various comorbid disorders. All had been treated with serotonin reuptake inhibitors at adequate dosages for at least 6 months, but had failed to respond. Consequently, they were shifted to citalopram, titrated up to the dose of 40 mg, within 2 weeks. After 4 months of this regimen, 14 out of the total of 18 patients had shown a reduction in OC symptoms, as assessed by the decrease in the Yale-Brown Obsessive Compulsive Scale total score; no relevant side-effects were reported, except for a mild nausea in four patients within the first few days of treatment, which quickly disappeared. The use of citalopram would appear to be an useful strategy in refractory OCD cases.

Abstract
BACKGROUND The aim of this study was to evaluate exercise performance in patients affected by anorexia nervosa. METHODS We studied 19 patients (all females, mean age 23.1 +/- 5.2 years) affected by anorexia nervosa (mean weight 37.3 kg, body mass index 14.04 +/- 1.4 kg/m2) and 20 constitutionally thin women, matched for age, height and physical activity, with a body mass index < 19 kg/m2. All these women underwent clinical examination, standard ECG and a cardiopulmonary stress test. RESULTS Patients affected by anorexia nervosa showed a lower heart rate and systolic blood pressure at peak exercise (148.8 +/- 13.8 vs 171 +/- 9.2 b/min, p < 0.001, and 130 +/- 9.5 vs 152 +/- 11.2 mmHg, p < 0.001), work load (85.5 +/- 15.1 vs 117.2 +/- 20.3 W, p < 0.001), rate-pressure product (19 371 +/- 2391 vs 25,986 +/- 2218 b/min/mmHg, p < 0.001), oxygen uptake (VO2) at rest and maximum VO2 (5.4 +/- 1.7 vs 7.1 +/- 1.1 ml/kg/min, p < 0.001, and 28.08 +/- 6.3 vs 40.2 +/- 7.1 ml/kg/min, p < 0.001), anaerobic threshold (15.7 +/- 1.9 vs 20.4 +/- 2.1 ml/kg/min, p < 0.001), VO2 during exercise (9.5 +/- 1.2 vs 12.8 +/- 1.3 ml/min/W, p < 0.001), maximum minute ventilation (34.5 +/- 9.9 vs 48.4 +/- 10.3 /min, p < 0.001), and oxygen pulse (7.2 +/- 2 vs 10.9 +/- 2.4 ml/b, p < 0.001). CONCLUSIONS These data show an abnormal working capacity and cardiovascular responses to exercise in patients affected by anorexia nervosa. The low VO2, both at rest and during exercise, allows them to maintain a relatively high level of physical activity, which contributes to increase the energy expenditure needed for weight loss.

Abstract
1. The authors present here a sensitive and rapid reversed-phase liquid chromatographic method which enables the simultaneous analysis in plasma of two different drugs and their metabolites: the atypical neuroleptic clozapine and the tricyclic antidepressant clomipramine. 2. Samples and the internal standard (dibenzepine) were extracted through automated solid-phase procedure, evaporated dryness and injected into the chromatograph. Mobile phase was a mixture of water and acetonitrile (63:37, v:v) containing TEMED and triethylamine. The total chromatographic time was of 14 min and analyte peaks were detected by means of an ultraviolet spectrophotometer preset at 254 nm. 3. Results revealed an assay sensitivity of 5 microg/L for clozapine or norclozapine and of 10 microg/L for clomipramine and desmethylclomipramine. Recoveries for these drugs and their metabolites were more than 60% and their coefficient of variation (within day and day-to-day) ranged from 1.3 % to 2.5 %. In spiked plasma, within day and day-to-day coefficients of variability (CV) were less than 5%. The simultaneous evaluation of these two drugs with adequate sensitivity and precision makes it particularly useful for therapeutic drug monitoring during mono- or polypharmacotherapy.

Abstract
Although the precise etiologic nature of obsessive-compulsive disorder (OCD), one of the most common psychiatric conditions, is unknown, several findings indicate involvement of the serotonin (5-HT) transporter. Apart from the specific effects of selective 5-HT reuptake inhibitors, other studies show decreased functionality of the platelet 5-HT transporter in OCD. In this report, the authors combine data from two independent studies of patients with OCD, showing both an increased activity of protein kinase type C (PKC) and a decreased activity of protein kinase type A (PKA). The authors propose a unifying hypothesis that OCD might be determined by an imbalance between PKC and PKA, with a prevalence of the former and, more generally, of the phosphoinositide over the cyclic adenosine monophosophate (cAMP) pathway. Should this hypothesis prove correct, the path would be open for new therapeutic interventions in the treatment of OCD.

Abstract
We investigated the distribution of serotonin (5-HT) receptors of type 3 (5-HT3) in human brain areas, by means of the the specific binding of [3H]GR65630. The brains were obtained during autoptic sessions from 6 subjects. Human brain membranes and the binding of [3H]GR65630 were carried out according to standardized methods. The highest density (Bmax +/- SD, fmol/mg protein) of [3H]GR65630 binding sites was found in area postrema (13.1+/-9.7), followed at a statistically lower level, by nucleus tractus solitarius (6.7+/-3.4), nervus vagus (5.5+/-2.1), striatum (4.8+/-2.4) with a progressive decrease in amygdala, olivar nuclei, hippocampus, olfactory bulbus and prefrontal cortex, and then by the other cortical areas and the cerebellum, where no binding was detected. These observations extend previous findings on the distribution of 5-HT3 receptors and confirm interspecies variations that might explain the heterogeneous properties of 5-HT3 receptors in different animals.

Abstract
DSM IV is a simple, reliable diagnostic system with many advantages. However, DSM diagnostic criteria may not provide sufficient characterization of clinically significant symptoms. We have undertaken a project to assess an array (spectrum) of clinical features associated with different DSM Disorders. The purpose of this paper is to report on reliability of assessment instruments for Panic-Agoraphobic Spectrum (PAS), to document convergent validity of PAS symptom groupings, and to confirm the relationship between PAS and DSM IV Panic Disorder (PD). We studied 22 normal controls and 95 outpatients who met criteria for Panic Disorder with and without lifetime Major Depression, and Major Depression or Obsessive Compulsive Disorder without lifetime Panic Disorder. Assessment instruments had excellent reliability and there was good concordance between interview and self-report formats. PAS scores were highest in subjects with PD, followed by outpatients without PD, and were lowest in normal controls. PAS scores varied among PD patients, and a subgroup of patients without PD scored high on PAS. We conclude that PAS can be reliably assessed, and that it describes a valid, coherent constellation of features associated with DSM IV Panic Disorder, but providing additional important clinical information.
