Co-occurring PTSD in intensive OCD treatment: Impact on treatment trajectory vs. response.

Background: Obsessive-compulsive disorder (OCD) and co-occurring posttraumatic stress disorder (PTSD) is associated with more severe and chronic OCD. However, findings regarding treatment effectiveness of cognitive behavioral treatment (CBT) with exposure and response prevention (ERP) with this comorbidity are mixed. Research aimed at understanding the precise barriers to OCD treatment effectiveness for individuals with co-occurring PTSD may help elucidate unique treatment needs.

Predictors of Long-Term Exercise Engagement in Patients With Obsessive-Compulsive Disorder: The Role of Physical Activity Enjoyment.

Most U.S. adults, even more so those with psychiatric conditions like obsessive-compulsive disorder (OCD), do not engage in the recommended amount of physical activity (PA), despite the wide array of physical and mental health benefits associated with exercise.

Directionality of change in obsessive compulsive disorder and depression over six years of prospective follow-up.

Major Depressive Disorder (MDD) is often comorbid with obsessive-compulsive disorder (OCD) yet little is known about the directionality of the association between OCD and depression symptoms. We aim to investigate the effect OCD symptoms has on depression symptoms and vice versa over an extended period of time. This is one of the first longitudinal studies to evaluate the relationship between OCD and depression in a large clinical sample.

Personality traits as predictors of OCD remission: A longitudinal study.

Background: Personality traits may confer vulnerability to psychopathology. However, few studies have examined the association between personality traits and obsessive-compulsive disorder (OCD) course. The present study investigates personality traits, OCD symptom severity, and illness duration as a predictor of OCD remission.

Behavioral Therapy Teams for Obsessive-Compulsive Disorder: Lessons Learned From a Pilot Randomized Trial in a Community Mental Health Center.

Community mental health centers (CMHCs) provide the majority of mental health services for low-income individuals in the United States. Exposure and response prevention (ERP), the psychotherapy of choice for obsessive-compulsive disorder (OCD), is rarely delivered in CMHCs. This study aimed to establish the acceptability and feasibility of testing a behavioral therapy team (BTT) intervention to deliver ERP in CMHCs.

Impact of the peripartum period on the longitudinal course of obsessive-compulsive disorder.

Some women are vulnerable to developing new onset obsessive-compulsive disorder (OCD) or having an exacerbation of pre-existing OCD during reproductive cycle events. Reports on the impact of the peripartum period on pre-existing OCD are inconsistent, with both worsening and improving symptom severity described. Studies have primarily been retrospective or have collected few data points, which limits the investigators' ability to capture the range of OCD symptoms during this time period, systematically and prospectively.

Melatonin synthesis in the optic lobes and midbrain of the grasshopper Oedipoda caerulescens.

The pathways of insect melatonin (MEL) biosynthesis apparently follow the same routes as those identified in vertebrates but information on MEL synthesis variations related with serotonin (5-HT), 5-hydroxy-indole acetic acid (5HIAA), and N-acetylserotonin (NAS) levels, as well as 5-HT N-acetyltransferase (NAT) activity throughout the day, is very limited in the insect nervous system. In the present study, the levels of MEL, metabolites (5-HT, NAS, and 5-HIAA) and enzyme NAT were determined in the optic lobes and the midbrain of the grasshopper Oedipoda caerulescens, in conditions of light and darkness. In both tissues, a different pattern of MEL synthesis was observed over the light/dark cycle.

The Brown Incompleteness Scale (BINCS): Measure development and initial evaluation.

Background: In recent years, incompleteness has received increased clinical attention as a core motivation underlying obsessive-compulsive spectrum disorders. Yet, assessment of incompleteness has relied almost exclusively on self-report and has assumed a unitary conceptualization of this phenomenon. Therefore, we sought to develop and validate a new multi-faceted clinician-administered measure of incompleteness.

Paritaprevir/ritonavir/ombitasvir plus dasabuvir in HIV/HCV-coinfected patients with genotype 1 in real-life practice.

Background Data on the efficacy, safety, and concomitant use with other drugs of the combination ritonavir-boosted paritaprevir/ombitasvir plus dasabuvir (PrOD) in HIV/HCV-coinfected patients in real life are limited. The objectives of this study were to analyze these topics in HIV/HCV-coinfected subjects bearing HCV genotype 1 (GT1). Methods One hundred and eighty-two HIV/HCV-coinfected patients with GT1 (87 1a, 71 1b, 23 other) treated with PrOD, plus ribavirin (RBV) in 119 cases, in routine clinical practice were analyzed.

A pilot randomized controlled trial of aerobic exercise as an adjunct to OCD treatment.

Objective: The purpose of the current study was to conduct a randomized controlled trial testing the efficacy of aerobic exercise for decreasing OCD symptom severity, other mental health outcomes, and increasing exercise behaviors and cardiorespiratory fitness among individuals with OCD.

Method: Fifty-six patients (64% female; mean age=38.8years) with OCD and a Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) score of 16 or greater despite engaging in OCD treatment were randomized to 12-weeks of supervised plus home-based moderate-intensity aerobic exercise (AE; n=28) or to 12-weeks of health education sessions (HE; n=28).

The impact of lifetime PTSD on the seven-year course and clinical characteristics of OCD.

Research has suggested that the co-occurrence of PTSD in individuals with OCD is associated with more severe symptoms and less responsivity to empirically supported treatment as compared to individuals with OCD and no history of PTSD. However, much of this work has been limited by non-empirical case report design, cross-sectional and retrospective analyses, or small sample sizes. The current study extended this research by comparing the clinical characteristics of individuals with OCD with and without a lifetime PTSD diagnosis in a large, naturalistic, longitudinal sample over the course of seven years.

Changes in Liver Steatosis After Switching From Efavirenz to Raltegravir Among Human Immunodeficiency Virus-Infected Patients With Nonalcoholic Fatty Liver Disease.

Background: Antiretroviral drugs with a lower potential to induce hepatic steatosis in human immunodeficiency virus (HIV) infection need to be identified. We compared the effect of switching efavirenz (EFV) to raltegravir (RAL) on hepatic steatosis among HIV-infected patients with nonalcoholic fatty liver disease (NAFLD) receiving EFV plus 2 nucleoside analogues.

Methods: HIV-infected patients on EFV plus tenofovir/emtricitabine or abacavir/lamivudine with NAFLD were randomized 1:1 to switch from EFV to RAL (400 mg twice daily), maintaining nucleoside analogues unchanged, or to continue with EFV plus 2 nucleoside analogues.

HIV-coinfected patients respond worse to direct-acting antiviral-based therapy against chronic hepatitis C in real life than HCV-monoinfected individuals: a prospective cohort study.

Objective: HIV/HCV-coinfected patients and hepatitis C virus (HCV) monoinfected subjects are thought to respond equally to direct-acting antiviral (DAA)-based therapy despite the lack of data derived from clinical trials. This study is aimed to evaluate the impact of HIV coinfection on the response to DAA-based treatment against HCV infection in the clinical practice.

Patients And Methods: In a prospective multicohort study, patients who initiated DAA-based therapy at the Infectious Disease Units of 33 hospitals throughout Spain were included.

App-guided exposure and response prevention for obsessive compulsive disorder: an open pilot trial.

Although effective treatments for obsessive-compulsive disorder (OCD) exist, there are significant barriers to receiving evidence-based care. Mobile health applications (Apps) offer a promising way of overcoming these barriers by increasing access to treatment. The current study investigated the feasibility, acceptability, and preliminary efficacy of LiveOCDFree, an App designed to help OCD patients conduct exposure and response prevention (ERP).

A cross-cultural clinical comparison between subjects with obsessive-compulsive disorder from the United States and Brazil.

Although OCD is a global problem, the literature comparing, in a direct and standardized way, the manifestations across countries is scarce. Therefore, questions remain as to whether some important clinical findings are replicable worldwide, especially in the developing world. The objective of this study was to perform a clinical comparison of OCD patients recruited in the United States (U.

Symptom subtype and quality of life in obsessive-compulsive disorder.

Quality of life (QoL) is significantly impaired in OCD across several facets of life, such as social, occupational, and family functioning, subjective sense of well-being, and enjoyment of leisure activities. The present study examined the relationship between 5 symptom subtypes of OCD (contamination, symmetry, hoarding, overresponsibility for harm, and taboo) and QoL. Participants were 325 adults with OCD enrolled in the Brown Longitudinal Obsessive Compulsive Study.

The PNPLA3 Genetic Variant rs738409 Influences the Progression to Cirrhosis in HIV/Hepatitis C Virus Coinfected Patients.

Contradictory data about the impact of the rs738409 steatosis-related polymorphism within PNPLA3 gene on liver fibrosis progression in HIV/hepatitis C virus (HIV/HCV)-coinfected patients have been reported. Our objective was to test whether this, and other polymorphisms previously related to fatty liver disease in HIV infection linked to SAMM50 or LPPR4 genes, influence liver fibrosis progression in HIV/HCV-coinfected individuals. Three hundred and thirty two HIV/HCV-coinfected patients who consecutively attended four Spanish university hospitals from November 2011 to July 2013 were included.

Parental Accommodation Predicts Symptom Severity at Long-term Follow-Up in Children with Obsessive-Compulsive Disorder.

Pediatric obsessive-compulsive disorder (OCD) is a chronic condition affecting millions of children. Though well intentioned, accommodation (i.e.

Changes in the response to treatment against chronic hepatitis C between 1999 and 2015: data from a prospective cohort.

Background: The drug options and strategies for treatment against hepatitis C virus (HCV) infection have changed considerably in the last few years. The aim of this study was to compare the changes in the proportion of nonresponders and patients who achieved a sustained virologic response (SVR) from 1999 to 2015 in one single cohort.

Patients And Methods: A total of 522 patients treated against chronic hepatitis C were included prospectively.

An empirical investigation of incompleteness in a large clinical sample of obsessive compulsive disorder.

Obsessive Compulsive Disorder (OCD) is a disorder with heterogeneous clinical presentations. To advance our understanding of this heterogeneity we investigated the prevalence and clinical features associated with incompleteness (INC), a putative underlying core feature of OCD. We predicted INC would be prominent in individuals with OCD and associated with greater severity and impairment.

Food intake inhibition in rainbow trout induced by activation of serotonin 5-HT2C receptors is associated with increases in POMC, CART and CRF mRNA abundance in hypothalamus.

In rainbow trout, the food intake inhibition induced by serotonin occurs through 5-HT2C and 5-HT1A receptors, though the mechanisms involved are still unknown. Therefore, we assessed if a direct stimulation of 5-HT2C and 5-HT1A serotonin receptors (resulting in decreased food intake in rainbow trout), affects gene expression of neuropeptides involved in the control of food intake, such as pro-opiomelanocortin (POMC), cocaine- and amphetamine-regulated transcript (CART), corticotrophin releasing factor (CRF), and agouti-related peptide (AgRP). In a first set of experiments, the injection of the 5-HT2C receptor agonists MK212 (60 μg kg(-1) icv) and WAY 161503 (1 mg kg(-1) ip), and of the 5-HT1A receptor agonist 8-OH-DPAT (1 mg kg(-1) ip and 30 μg kg(-1) icv) induced food intake inhibition.
