Obsessive-compulsive disorder (OCD) is a polygenic neuropsychiatric disorder characterized by repetitive thoughts and behaviors that cause distress. The pathogenic repeat expansion [GGGGCC]n found at the C9orf72 locus is the most common cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), and has also been documented in patients with psychosis and schizophrenia. Furthermore, obsessions and compulsions have been identified in patients diagnosed with ALS and/or FTD and carrying the pathogenic repeat expansion...

INTRODUCTION: There is very limited data on the use of MRI based perfusion imaging to select patients with acute ischemic stroke and large vessel occlusion (LVO) for intraarterial therapy beyond 6h from onset. Our aim is to report the outcome of patients with acute ischemic stroke and large artery occlusion who presented beyond 6h from onset, had favorable MRI imaging profile, and underwent mechanical embolectomy. METHODS: This is a single institution (Rhode Island Hospital) retrospective study between December 1st, 2015, and July 30th, 2016 that included patients with acute ischemic stroke and proximal LVO with CT ASPECTS of 6 or more and 6-24h from symptom onset who were assessed for mechanical embolectomy using MRI based perfusion imaging...

Caffeine is neuroprotective in animal models of Parkinson's disease (PD) and caffeine intake is inversely associated with the risk of PD. This association may be influenced by the genotype of GRIN2A, which encodes an NMDA-glutamate-receptor subunit. In two placebo-controlled studies, we detected no association of caffeine intake with the rate of clinical progression of PD, except among subjects taking creatine, for whom higher caffeine intake was associated with more rapid progression. We now have analyzed data from 420 subjects for whom DNA samples and caffeine intake data were available from a placebo-controlled study of creatine in PD...

Arterial hypertension (HT) and other vascular pre-existing conditions (PEC) generate asymptomatic brain damage which increases the occurrence of stroke and cognitive decline. The aim of this work was to explore if serum antibodies against the NR2 subunit of the NMDA receptor (NR2Ab) could predict subclinical brain damage (SBD) in hypertensive patients with PEC. Forty seven neurologically asymptomatic hypertensive subjects were classified according to the number of PEC (retinopathy, overweight/obesity, diabetes mellitus and dyslipidemia)...

OBJECTIVES: Associations between parental occupational pesticide exposure and childhood acute lymphoblastic leukemia (ALL) vary across studies, likely due to different exposure assessment methodologies. METHODS: We assessed parental occupational pesticide exposure from the year before pregnancy to the child's third year of life for 669 children diagnosed with ALL and 1021 controls. We conducted expert rating using task-based job modules (JM) to estimate exposure to pesticides among farmer workers, gardeners, agricultural packers, and pesticide applicators...

BACKGROUND: Previous studies indicate that parental externalizing behavior (EB) is a robust risk factor for alcohol use disorder (AUD) in their children, and that this is due to both inherited genetic liability and environmental exposure. However, it remains unclear whether the effects of exposure to parental EB vary as a function of timing and/or chronicity. METHODS: We identified biological parents with an alcohol use disorder, drug abuse, or criminal behavior, during different periods of their child's upbringing, using Swedish national registries...

This study investigated the effects of cold plasma treatment (CPT) on the inhibition of Salmonella typhimurium on radish sprouts and the quality attributes of the sprouts. Radish sprouts were treated with nitrogen (N2)-cold plasma at 900W and 667Pa for 0, 2, 5, 10, and 20min using a microwave-powered CPT system. The sensory attributes of the radish sprouts, appearance and odor, were evaluated before and after the treatment. The effects of N2-CPT for 10min on microbial growth and the quality attributes of the radish sprouts were evaluated during storage for 12days at 4 and 10°C...

Stressful conditions can stimulate the accumulation of carotenoids in some microalgae. To obtain more knowledge of the stress response, we studied the effects of different N concentrations on unicellular content of carotenoids using Raman spectroscopic technique; cellular stoichiometric changes and the fluorescence parameters of Chlorella vulgaris were concomitantly studied. Initially, we optimized the Raman scattering conditions and demonstrated the feasibility of unicellular carotenoid analysis by Raman spectroscopic technique...

Group schema therapy (GST) has been proposed as a novel long-term treatment programme for borderline and cluster C personality disorders. We implemented a short-term GST programme (12-15 sessions, based on the manual by Farrell and Shaw (2012), including both cognitive / behavioural and experiential interventions for in-patients (n=9) with either borderline or cluster C personality disorders (and axis I co-morbidities) treated in a (sub)acute psychiatric in-patient setting. We evaluated pre- and post-treatment self-report of maladaptive and adaptive schema modes (using the SMI) and early maladaptive schemas (YSQ-3), as well as overall symptom severity (brief symptom check list, BSCL-53-S), patient satisfaction (ZUF-8) and group climate and coherence (GCQ-S)...

Differentiated vulvar intrapeithelial neoplasia (dVIN) is an human papillomavirus (HPV)-independent precursor of squamous cell carcinoma (SCC), and the aim of this study was to better characterize its natural history. Cases of dVIN were identified from the pathology archives. Outcomes of patients with dVIN only, without associated invasive SCC, were compared with a cohort of patients with high-grade squamous intraepithelial lesion [HSIL(VIN3)]. Eighteen patients diagnosed with dVIN with adjacent invasive SCC (SCC/dVIN) and 7 patients with dVIN only, without invasive carcinoma, were identified...

Acquired von Willebrand disease increases bleeding risk in patients implanted with a continuous-flow left ventricular assist device. Lower aspirin doses decrease the risk of bleeding without an increased risk of embolic events. No published studies in the U.S. have compared the incidence of bleeding and thrombotic events between antithrombotic regimens with and without aspirin. A single-center, retrospective analysis was conducted of adult patients implanted with a HM II. Patients received warfarin and aspirin 81 mg daily or warfarin alone...

BACKGROUND: Pain and adhesion are problematic issues after surgery. Lidocaine has analgesics and anti-inflammatory properties, and poloxamer/alginate/CaCl2 (PACM) is a known antiadhesive agent. We hypothesized that the novel combination of lidocaine as chemical barrier and PACM as physical barrier would be beneficial for both postoperative pain and adhesion. The purpose of this study was to investigate the effects of lidocaine-loaded PACM in a rat model of incisional pain. Primary outcome was to evaluate between-group differences for the mechanical withdrawal threshold (MWT) measured by von Frey filament in various concentrations of lidocaine-loaded PACM applied, PACM applied, and sham-operated groups...

Traditionally, the success of a researcher has been judged by the number of publications he or she has published in peer-review, indexed, high impact journals. However, to quantify the impact of research in the wider scientific community, a number of traditional metrics have been used, including Impact Factor, SCImago Journal Rank, Eigenfactor Score, and Article Influence Score. This article attempts to provide a broad overview of the main traditional impact metrics that have been used to assess scholarly output and research impact...
