Antipsychotics in treatment-resistant Obsessive-Compulsive Disorder: which antipsychotic, which dose and how long antipsychotic addition should be maintained

Objectives: Treatment-resistant Obsessive-Compulsive Disorder (OCD) patients are defined as those who undergo adequate trials of first-line therapies without achieving a satisfactory response. First line treatments for OCD include both serotonin reuptake inhibitors (SRIs) and cognitive behavior therapy (CBT). Because of the high number of OCD patients not responding to first-line treatments (40-60%) and considering the even greater prevalence rate of residual symptoms and significant impairment shown in patients previously described as \u201cclinical responders\u201d, the question of the proper treatment of resistant OCD is a clinically meaningful and a practical issue for psychiatrists. Antipsychotic augmentation proved to be an effective strategy for resistant OCD. However, there are unresolved questions concerning which antipsychotic is effective (or more effective) and how antipsychotics should be used in terms of doses and duration of treatment. The purpose of this study is to systematically review available studies on antipsychotic augmentation for treatment-resistant OCD, in order to guide the practical choice. Materials and methods: We searched on PubMed, Psychnet and Cochrane Libraries from inception to January 2016. Articles published in English and related to the use of antipsychotics in OCD were considered. We evaluated meta-analyses, systematic reviews and randomized controlled trials of adult patients with treatment-resistant OCD. Results: Antipsychotic augmentation is an evidence-based option for treatmentresistant OCD, with a response rate of approximately 50% within the first 4-to6 weeks. Aripiprazole (10-15\ua0mg/day) and risperidone (0.5-2\ua0mg/day) are effective, olanzapine (10\ua0mg/day) is possibly effective. Haloperidol addition is also a viable option, particularly in patients with comorbid tic disorders. Given results of studies performed to date quetiapine should be regarded as non-effective. Preliminary results from open label studies suggest that antipsychotic augmentation, once effective, should be maintained in order to maintain remission. Conclusions: Not all antipsychotics are effective as add-on treatments in resistant OCD. Characteristics of patients and side effects generally associated with each different antipsychotic may guide the practical choice. Further research is required concerning the comparative effectiveness among antipsychotics, the optimal target dose and the ideal duration of antipsychotic addition. In our opinion, antipsychotic augmentation in patients who responded to this treatment should be maintained in order to prevent relapses. However, clinicians must remember patients\u2019 exposure to the common and serious adverse effects associated with long-term antipsychotic administration, especially metabolic disturbances

Severe obsessive-compulsive disorder (OCD): socio-demographic and clinical features

Aim: the aim of the study is to evaluate the socio-demographic and clinical features with prognostic value in predicting evolution in severe OCD.Materials and methods: patients with a main diagnosis of OCD were recruited according to DSM-IV criteria. Socio-demographic and clinical features were assessed by mean of a semi-structured interview and clinical rating scales (Y-BOCS, HAM-A, HAM-D and SCID-II). Two subgroups were compared according to the severity of symptoms (severe vs mild-moderate).Results: the total sample was made up of 450 OCD subjects aged 34.5±12.1, with a mean age of onset 22.3±9.1; 215 subjects (47.8%) were females. Patients with severe OCD (Y-BOCS ≥ 32) showed a more insidious onset and a more chronic course compared to patients with mild-moderate symptoms. Other predictors of increased OCD severity were washing and hoarding compulsions. Lastly, the severity of the obsessive-compulsive condition was higher when it was associated either with mood disorders or with Axis II disorders (particularly Cluster A).Discussion: our study shows a correlation between severe OCD and severity predictors such as functional impairment and mood disorders. Furthermore washing and hoarding symptoms, lifetime comorbity with mood disorders and Cluster A personality disorders seem to predict OCD severity

Curcumin and Andrographolide Co-Administration Safely Prevent Steatosis Induction and ROS Production in HepG2 Cell Line

Non-alcoholic fatty liver disease (NAFLD) is an emerging chronic liver disease worldwide. Curcumin and andrographolide are famous for improving hepatic functions, being able to reverse oxidative stress and release pro-inflammatory cytokines, and they are implicated in hepatic stellate cell activation and in liver fibrosis development. Thus, we tested curcumin and andrographolide separately and in combination to determine their effect on triglyceride accumulation and ROS production, identifying the differential expression of genes involved in fatty liver and oxidative stress development. In vitro steatosis was induced in HepG2 cells and the protective effect of curcumin, andrographolide, and their combination was observed evaluating cell viability, lipid and triglyceride content, ROS levels, and microarray differential gene expression. Curcumin, andrographolide, and their association were effective in reducing steatosis, triglyceride content, and ROS stress, downregulating the genes involved in lipid accumulation. Moreover, the treatments were able to protect the cytotoxic effect of steatosis, promoting the expression of survival and anti-inflammatory genes. The present study showed that the association of curcumin and andrographolide could be used as a therapeutic approach to counter high lipid content and ROS levels in steatosis liver, avoiding the possible hepatotoxic effect of curcumin. Furthermore, this study improved our understanding of the antisteatosis and hepatoprotective properties of a curcumin and andrographolide combination

Real-time evaluation of longitudinal peak systolic strain (speckle tracking measurement) in left and right ventricles of athletes

<p>Abstract</p> <p>Background</p> <p>Strain, and particularly Longitudinal Peak Systolic Strain (LPSS), plays a role in investigating the segmental and overall contractility of the heart which is a particularly interesting feature in athletes in whom regular training determines several morphological and functional modifications in both the ventricles, that normally work at different loads. Speckle tracking techniques assess the LPSS of LV and RV from B-mode imaging in real time, with uniform accuracy in all segments, and can verify the possible dissimilar segmental contributions of the two chambers to overall myocardial contraction. The aim of the study is to quantify the LPSS in real time in both the ventricles in order to estimate any possible different deformation properties in them during a systolic period.</p> <p>Methods</p> <p>32 subjects (20 athletes and 18 controls) were submitted to a standard echocardiographic examination at rest and after a Hand Grip (HG) stress. From a four-chamber-view image, the LPSS parameter was measured with Speckle Tracking analysis in the basal and medium-apical segments of the two ventricles, at rest and after HG.</p> <p>Results</p> <p>In both athletes and controls, LPSS values were significantly higher in the RV of athletes (RV LPSS ^{medium-apical}-23.87 ± 4.94; ^{basalfreewall}-25.04 ± 4.12 at rest) and controls (RV LPSS^{medium-apical}-25.21 ± 4.97; ^{basalfreewall}-28.69 ± 4.62 at rest) than in the LV of both (athletes LV LPSS ^{medium-apical}-18.14 ± 4.16; ^{basallateralwall}-16.05 ± 12.32; controls ^{medium-apical}-18.81 ± 2.64; ^{basallateralwall}-19.74 ± 3.84) With the HG test a significant enhancement of the LPSS(with P < .05) in the medium-apical segments of LV and RV was evident, but only in athletes; there was no modification of the standard echo-parameters in either group.</p> <p>Conclusion</p> <p>ST analysis is an easy method for investigating the contractility of the RV through deformation parameters, showing greater involvement of the RV than LV at rest. In athletes only, after isometric stress the two ventricles show particular myocardial deformation properties of the regions around the apex where the curvature of the wall is more marked. The clinical application of this new approach in athletes and normal subjects requires further investigation.</p

The Hot and Energetic Universe: The close environments of supermassive black holes

Most of the action in Active Galactic Nuclei (AGN) occurs within a few tens of gravitational radii from the supermassive black hole, where matter in the accretion disk may lose up to almost half of its energy with a copious production of X-rays, emitted via Comptonization of the disk photons by hot electrons in a corona and partly reflected by the accretion disk. Thanks to its large effective area and excellent energy resolution, Athena+ contributions in the understanding of the physics of accretion in AGN will be fundamental - and unique - in many respects. It will allow us to map the disk-corona system - which is crucial to understand the mechanism of energy extraction and the relation of the corona with winds and jets - by studying the time lags between reflected and primary photons. These lags have been recently discovered by XMM-Newton, but only Athena+ will have the sensitivity required to fully exploit this technique. Athena+ will also be able e.g. to determine robustly the spin of the black hole in nearby sources (and to extend these measurements beyond the local Universe), to establish the nature of the soft X-ray components, and to map the circumnuclear matter within the AGN inner parsec with unprecedented details.Comment: Supporting paper for the science theme "The Hot and Energetic Universe" to be implemented by the Athena+ X-ray observatory (http://www.the-athena-x-ray-observatory.eu). 9 pages, 8 figure
