Brain responses of dysphoric and control participants during a self-esteem implicit association test.
2021
Previous studies have reported lowered implicit self-esteem at the behavioral level among depressed individuals. However, brain responses related to the lowered implicit self-esteem have not been investigated in people with depression. Here, event-related potentials were measured in 28 dysphoric participants (individuals with elevated amounts of depressive symptoms) and 30 control participants during performance of an implicit association task (IAT) suggested to reflect implicit self-esteem. Despite equivalent behavioral performance, differences in brain responses were observed between the dysphoric and the control groups in late positive component (LPC) within 400-1,000 ms poststimulus lat…
Chronic skin disease and levels of physical activity in 17 777 Spanish adults: a cross-sectional study
2021
Background: To date there is limited literature on the prevalence of chronic skin conditions and its association with levels of physical activity (PA) in Spain. Aim: To determine the prevalence of chronic skin disease and to compare levels of PA between people with and without chronic skin disease in a large representative sample of Spanish adults aged 15–69 years. Methods: Data from the Spanish National Health Survey 2017 were analysed. Chronic skin disease was assessed using a yes/no question. PA was measured using the short form of the International Physical Activity Questionnaire. Total PA metabolic equivalent of task min/week were calculated, and PA was included in the analyses as a co…
Intragenic KANSL1 mutations and chromosome 17q21.31 deletions: broadening the clinical spectrum and genotype-phenotype correlations in a large cohort…
2015
Background The 17q21.31 deletion syndrome phenotype can be caused by either chromosome deletions or point mutations in the KANSL1 gene. To date, about 60 subjects with chromosome deletion and 4 subjects with point mutation in KANSL1 have been reported. Prevalence of chromosome deletions compared with point mutations, genotype–phenotype correlations and phenotypic variability have yet to be fully clarified. Methods We report genotype–phenotype correlations in 27 novel subjects with 17q21.31 deletion and in 5 subjects with KANSL1 point mutation , 3 of whom were not previously reported. Results The prevalence of chromosome deletion and KANSL1 mutation was 83% and 17%, respectively. All patient…
Alliesthesia in visual and auditory sensations from environmental signals.
2007
'Alliesthesia' describes the fact that sensory stimuli can arouse pleasant or unpleasant sensations according to the internal state of a person. In the present work, the hedonicity aroused by stimuli from the environment in visual and auditory sensations was evaluated in 5 situations: 1) daytime without sensory stimulations (no video-tape); 2) daytime with poor sensory stimulations (uninteresting video-tape film); 3) daytime with rich sensory stimulations (interesting chosen movie on video-tape); 4) night-time without sensory stimulations (no video-tape); 5) night-time with poor sensory stimulations (uninteresting video-tape). During the day, hedonic ratings decreased with time in the no- a…
Analysis of the gastrin-releasing peptide receptor gene in Italian patients with autism spectrum disorders
2008
The gastrin-releasing peptide receptor (GRPR) was implicated for the first time in the pathogenesis of Autism spectrum disorders (ASD) by Ishikawa-Brush et al. [Ishikawa-Brush et al. (1997): Hum Mol Genet 6: 1241-1250]. Since this original observation, only one association study [Marui et al. (2004): Brain Dev 26: 5-7] has further investigated, though unsuccessfully, the involvement of the GRPR gene in ASD. With the aim of contributing further information to this topic we have sequenced the entire coding region and the intron/exon junctions of the GRPR gene in 149 Italian autistic patients. The results of this study led to the identification of four novel point mutations, two of which, that…
Evidence for association between structural variants in lissencephaly-related genes and executive deficits in schizophrenia or bipolar patients from …
2008
There is evidence for an association between structural variants in genes for lissencephaly, which are involved in neuronal migration, and prefrontal cognitive deficits in schizophrenia and bipolar patients. On the basis of these intriguing findings, we analyzed 16 markers located in the lissencephaly critical region (LCR in chromosome 17p13.3) in 124 schizophrenic, 56 bipolar, and 141 healthy individuals. All recruits were from a Spanish population isolate of Basque origin that is characterized by low genetic heterogeneity. In addition, we examined whether structural genomic variations in the LCR were associated with executive cognition. Twenty-three patients (12.8%), but none of the contr…
Acute stress impairs reward positivity effect in probabilistic learning
2019
Decision making based on feedback learning requires a series of cognitive processes, including estimating the probability of particular outcomes and modulating expectations between expected versus actual outcomes. It has been suggested that stress affects decision making and subsequent processing of feedback valence and magnitude. However, less is known about the effect of acute stress on reward expectancy. In the current study, participants performed a probabilistic learning task, in which they learned an association between response and feedback within different reward expectancy trials (30% and 70%) under the conditions of stress (threat of shock) and safety (no shock). We recorded event…
Simultaneous Pancreas Kidney Transplantation Improves Cardiovascular Autonomic Neuropathy with Improved Valsalva Ratio as the Most Precocious Test
2020
Background. Simultaneous pancreas-kidney (SPK) transplantation is a proven option of treatment for patients with type 1 diabetes mellitus (T1DM) and related end-stage renal disease. There is discrepancy between the results of different studies about the impact of prolonged normalization of glucose metabolism achieved by SPK on the course of diabetic complications including severe forms of diabetic neuropathy. The objective of the study was to evaluate the prevalence of cardiovascular autonomic neuropathy (CAN) in patients undergoing SPK transplantation and its evolution 10 years after transplantation. Methods. Prospective study of 81 patients transplanted in a single center from year 2002 t…
HCV infection and oral lichen planus: a weak association when HCV is endemic.
2004
Oral lichen planus (OLP), an immune-mediated disorder, has been reported as an extra-hepatic manifestation of Hepatitis C virus (HCV) infection, especially in HCV hyperendemic areas such as southern Europe and Japan. The aim of this study was to investigate from an epidemiological standpoint whether HCV infection is an important factor affecting the relative risk of OLP in a Mediterranean population or whether this relates to the degree of HCV endemicity. Two cohorts of OLP patients resident in two different regions of southern Italy (Campania and Sicily; n = 859) were evaluated for HCV infection status and categorized into five age classes to respective region-matched controls. No signific…
Adrenomedullin and arterial stiffness: integrative approach combining monocyte ADM expression, plasma MR-Pro-ADM, and genome-wide association study.
2014
Background— Adrenomedullin (ADM) is a circulating vasoactive peptide involved in vascular homeostasis and endothelial function. Single nucleotide polymorphisms of the ADM gene are associated with blood pressure variability, and elevated levels of plasma midregional proadrenomedullin (MR-pro-ADM) are associated with cardiovascular diseases. Methods and Results— We investigated the sources of variability of ADM gene expression and plasma MR-pro-ADM concentrations in the general population, and their relationship with markers of atherosclerosis. MR-pro-ADM levels were assessed in 4155 individuals who underwent evaluation of carotid intima-media thickness and arterial rigidity (reflection inde…
