People with Alcohol Use Disorders in Specialized Care in Eight Different European Countries
2015
Aim: To provide a description of patients receiving alcohol treatment in eight different European countries, including the level of comorbidities and functional limitations. Methods: Drinking behaviours, DSM-IV alcohol use disorder (AUD), mental and somatic comorbidities, disability and health services utilization of 1767 patients from various specialized treatment settings were assessed as representative for regions of eight European countries. Severity of alcohol dependence (AD) in terms of drinking level was compared with a large representative US sample.

Effect of gender on mitochondrial toxicity of Alzheimer's Abeta peptide.
2007
The aim of this article is to review the role of mitochondria in the pathogenesis of Alzheimer's disease. Additionally, the effect of gender on the incidence of Alzheimer's disease and the pathophysiological mechanisms involved will be discussed. Mitochondria, in the presence of Alzheimer's amyloid-beta peptide, increase the formation of reactive oxygen species which act both as damaging agents and also as signaling molecules. These radicals, in fact, unleash a mechanism involving the liberation of cytochrome c that leads to neuronal apoptosis. Notably, young females appear protected against the mitochondrial toxicity of amyloid-beta, likely due to the upregulation of antioxidant enzymes wh…
Predictability of oppositional defiant disorder and symptom dimensions in children and adolescents with ADHD combined type.
2010
BackgroundOppositional defiant disorder (ODD) is frequently co-occurring with attention deficit hyperactivity disorder (ADHD) in children and adolescents. Because ODD is a precursor of later conduct disorder (CD) and affective disorders, early diagnostic identification is warranted. Furthermore, the predictability of three recently confirmed ODD dimensions (ODD-irritable, ODD-headstrong and ODD-hurtful) may assist clinical decision making.MethodReceiver-operating characteristic (ROC) analysis was used in order to test the diagnostic accuracy of the Conners' Parent Rating Scale revised (CPRS-R) and the parent version of the Strength and Difficulties Questionnaire (PSDQ) in the prediction of …
Disease status, reasons for discontinuation and adverse events in 1038 Italian children with juvenile idiopathic arthritis treated with etanercept
2016
Background: Data from routine clinical practice are needed to further define the efficacy and safety of biologic medications in children with juvenile idiopathic arthritis (JIA). The aim of this analysis was to investigate the disease status, reasons for discontinuation and adverse events in Italian JIA patients treated with etanercept (ETN). Methods: In 2013, all centers of the Italian Pediatric Rheumatology Study Group were asked to make a census of patients given ETN after January 2000. Patients were classified in three groups: group 1 = patients still taking ETN; group 2 = patients discontinued from ETN for any reasons; group 3 = patients lost to follow-up while receiving ETN. All three…
Classical pediatric Hodgkin lymphoma in very young patients: the Italian experience
2019
Many studies have reported a more favorable outcome in younger patients with Hodgkin lymphoma (HL). The aims of this study were to find an appropriate age cutoff able to identify low-risk children and to describe the natural history of 135 very young patients affected by classic HL (cHL). The best age cutoff was identified at 7 years of age. EFS (p = .0451) and PFS (p = .00921) were significantly better in the group of younger patients. The OS rate at 10 years was 97.0% in the younger group and 92.5% in the older one (p = .0448). However, age was not found to be an independent prognostic factor in multivariate analysis and the better prognosis in younger patients seems to be related to more…
Genome-wide association scan of quantitative traits for attention deficit hyperactivity disorder identifies novel associations and confirms candidate…
2008
Contains fulltext : 70192.pdf (Publisher’s version ) (Closed access) Attention deficit hyperactivity disorder (ADHD) is a complex condition with environmental and genetic etiologies. Up to this point, research has identified genetic associations with candidate genes from known biological pathways. In order to identify novel ADHD susceptibility genes, 600,000 SNPs were genotyped in 958 ADHD proband-parent trios. After applying data cleaning procedures we examined 429,981 autosomal SNPs in 909 family trios. We generated six quantitative phenotypes from 18 ADHD symptoms to be used in genome-wide association analyses. With the PBAT screening algorithm, we identified 2 SNPs, rs6565113 and rs5526…
Genome-wide association scan of the time to onset of attention deficit hyperactivity disorder.
2008
Contains fulltext : 70149.pdf (Publisher’s version ) (Closed access) A time-to-onset analysis for family-based samples was performed on the genomewide association (GWAS) data for attention deficit hyperactivity disorder (ADHD) to determine if associations exist with the age at onset of ADHD. The initial dataset consisted of 958 parent-offspring trios that were genotyped on the Perlegen 600,000 SNP array. After data cleaning procedures, 429,981 autosomal SNPs and 930 parent-offspring trios were used found suitable for use and a family-based logrank analysis was performed using that age at first ADHD symptoms as the quantitative trait of interest. No SNP achieved genome-wide significance, and…
p38 MAP kinase drives the expression of mast cell-derived IL-9 via activation of the transcription factor GATA-1.
2007
Mast cells are able to produce a huge panel of mediators including the Th2-type cytokine IL-9, which is considered to be a key mediator for the pathogenesis of allergic asthma, but detailed information on the regulation of IL-9 transcription in mast cells has been scarce. Herein we provide evidence that the erythroid/myeloid transcription factor GATA-1, which is not expressed in Th2 cells, is a potent activator of IL-9 expression in murine bone marrow-derived mast cells (BMMC). Furthermore, in mast cells, but not in Th2 cells, production of IL-9 is sensitive to inhibition of p38 MAP kinase. As transactivation mediated by GATA-1 is also sensitive to inhibition of p38 MAP kinase, and GATA-1 i…
Reactive plasmacytoses are expansions of plasmablasts retaining the capacity to differentiate into plasma cells.
1999
Abstract Circulating plasma cells in 10 cases of reactive plasmacytosis had a shared phenotype with early plasma cell (CD19+CD38+ CD138+ CD40+CD45+ CD11a+ CD49e−CD56−). In most cases, a minor subpopulation of CD28+ plasma cells was also detected. Reactive plasma cells were highly proliferative, suggesting the presence of circulating progenitors (plasmablasts). After CD138+ plasma cell removal, highly proliferative CD138− plasmablasts differentiated into CD138+ plasma cells within a few days. This differentiation, which was associated with increased CD38 and decreased HLA-DR expression, was further confirmed by a large increase in intracellular Ig content (associated with Ig secretion) and w…
High mobility group box 1 potentiates the pro-inflammatory effects of interleukin-1β in osteoarthritic synoviocytes
2010
Introduction High mobility group box 1 (HMGB1) is released by necrotic cells or secreted in response to inflammatory stimuli. Extracellular HMGB1 may act as a pro-inflammatory cytokine in rheumatoid arthritis. We have recently reported that HMGB1 is released by osteoarthritic synoviocytes after activation with interleukin-1beta (IL-1β) The present study investigated the role of HMGB1 in synovial inflammation in osteoarthritis (OA). Methods HMGB1 was determined in human synovium using immunohistochemistry, comparing normal to OA. OA synoviocytes were incubated with HMGB1 at 15 or 25 ng/ml in the absence or presence of IL-1β (10 ng/ml). Gene expression was analyzed by quantitative PCR and pro…
