Prevalence of celiac disease among first degree relatives of Brazilian celiac patients

Background - Several studies have shown that celiac disease, an autoimmune disorder that occurs in genetically susceptible individuals, is highly prevalent among relatives of celiac patients. Aim - To determine the prevalence of celiac disease in a group of first degree relatives of Brazilian celiac patients. Methods - First degree relatives of celiac patients attending the Brasilia University Hospital Pediatric Gastroenterology Outpatient Clinic or the Celiac Disease Investigation Center, Brasília, DF, Brazil, between March 2001 and November 2004 were invited to undergo serological screening for celiac disease applying the IgA anti-endomysium antibody test (IgA-EMA). All positive IgA-EMA sera underwent a second screening using the IgA anti-tissue transglutaminase antibodies test. Duodenal or small intestinal biopsies were performed in all subjects positive to serological testing. Biopsy samples were classified as type (O) normal, (I) infiltrative, (II) infiltrative hyperplastic, (III) flat destructive, and (IV) atrophic hypoplastic. The final diagnosis was ascertained in subjects showing positive serological tests and a grade I to III small intestinal lesion. Results - Nine new cases of celiac disease were found among the 188 first degree relatives tested (4.8%). Conclusion - The present study confirms the high prevalence of celiac disease among first degree celiac patients’ relatives and reinforces the need of extensive diagnostic screening in this specific group.

Perceptions et croyances relatives à l’hygiène des mains chez les infirmières de deux hôpitaux de la République démocratique du Congo

Cette étude visait à documenter les perceptions et les croyances sur l’hygiène des mains chez des infirmières de deux hôpitaux de la République démocratique du Congo (RDC). Le modèle PRECEDE-PROCEED a guidé les travaux et permis de centrer l’analyse sur les facteurs prédisposants et les facteurs facilitants, éléments favorisant l’adoption des comportements de santé. Le devis utilisé est de type descriptif corrélationnel. Un échantillon de convenance incluant 74 infirmières recrutées dans les deux hôpitaux a été assemblé. Les données ont été recueillies au moyen d’un questionnaire auto-administré composé de 34 questions, tirées d’outils repérés dans la recension des écrits. Les questions portaient sur les connaissances, les perceptions au regard de l’hygiène des mains et l’accès aux infrastructures facilitant l’adoption de ce comportement. La collecte des données s’est déroulée à Kinshasa, capitale de la RDC. Les résultats révèlent d’importantes lacunes dans les connaissances. Les perceptions relatives aux normes sociales sont ressorties comme davantage favorables. Les résultats révèlent également des lacunes en ce qui a trait aux facteurs facilitants, notamment dans l’utilisation de la friction hydro-alcoolique. Par ailleurs, les infirmières les plus instruites et les plus expérimentées étaient plus nombreuses à percevoir l'importance de la pratique d’hygiène des mains. La discussion aborde quelques pistes en termes d’actions à entreprendre pour améliorer les comportements d’hygiène chez les infirmières dans les pays en développement telle la RDC.

Caregivers’ burden experienced by relatives living with a person suffering from schizophrenia

Abstract: Schizophrenia is a complex chronic disease that turns the affected person into a dependent and disorganized patient. This pathology is responsible for a major burden on the family members who are in charge of taking care of that person. Analyze to what extant can socio-demographic, clinical and environmental variables interfere with the burden felt by family members who live with someone suffering from schizophrenia; to analyze the relationship between a depressive mood state and the burden on the family members who live with a person suffering from schizophrenia were our objectives. As a methodology, quantitative and non-experimental, cross-sectional, descriptive and correlational study. The data collection was done through socio-demographic questionnaires; Vaz Serra and Pio Abreu’s Portuguese version of Beck Depression Inventory (1973); Zarit Burden Interview adapted by Sequeira (2007). 95 informal caregivers taking care of schizophrenic patients were assessed. Participants are mainly female (66%), aged 40 or over (79%) and 36 % are the patients’ mothers. Gender, age and existing family ties variables interfered significantly with the impact caused on the caregiver’s burden. There was a statistically significant correlation between the depressive symptomatology and the burden experienced by the family caregivers. Family/ informal caregiver experience several difficulties when they have to go through a daily process of taking care of a family member suffering from schizophrenia. This situation may cause exhaustion, conflicts, emotional suffering and even depressive symptomatology. This burden of care grows stronger as the patients are older, when they are male and when there are no families ties binding patient and caregiver. These variables must be taken into account in these caregivers’ service plans.

The well-being of relatives of patients with atrial fibrillation: a critical incident technique analysis

BACKGROUND: The well-being of relatives of patients having chronic heart diseases (CHD) has been found to be negatively affected by the patient's condition. Studies examining relatives of patients with atrial fibrillation (AF) indicate that their well-being may be affected in a similar manner, but further research is needed. AIM: To explore and describe critical incidents in which relatives of patients experience how AF affects their well-being and what actions they take to handle these situations. DESIGN AND METHOD: An explorative, descriptive design based on the critical incident technique (CIT) was used. Interviews were conducted with 19 relatives (14 women and five men) of patients hospitalised in southern Sweden due to acute symptoms of the AF. RESULTS: The well-being of relatives was found to be affected by their worries (patient-related health), as well as the sacri-ficing of their own needs (self-related health). In handling their own well-being, these relatives adjusted to and supported the patient (practical involvement), along with adjusting their own feelings and responding to the mood of the patients (emotional involvement). CONCLUSION: The well-being of relatives of patients with AF was affected depending on the patients' well-being. In their attempt to handle their own well-being, the relatives adjusted to and supported the patients. Further research is needed in order to evaluate the effects of support to relatives and patients respectively and together.

Application de stratégies visant à favoriser l’intégration de connaissances par des élèves de Techniques administratives ayant ou percevant avoir des difficultés relatives à des fonctions cognitives spécifiques

Le nombre d'élèves du collégial ayant présenté un diagnostic de trouble d'apprentissage ou de déficit d'attention (avec ou sans hyperactivité) aux autorités de leur institution scolaire s'est accru de façon considérable au cours de la dernière décennie. Comme seules les personnes souhaitant bénéficier de mesures particulières d'encadrement dans leur cégep doivent déclarer ces diagnostics, il est possible de croire qu'un nombre plus grand d'élèves que celui suggéré par les statistiques disponibles ait soit un trouble d'apprentissage ou un déficit d'attention. Le problème qui est à l'origine de cette recherche est composé de deux éléments. D'une part, il est possible qu'un trouble d'apprentissage soit le résultat du dysfonctionnement de plus d'une fonction cognitive et il est également possible que plusieurs troubles d'apprentissage coexistent. Cette complexité invite à agir, dans un contexte d'enseignement, sur des fonctions cognitives précises, plutôt que sur des troubles d'apprentissage en particulier. D'autre part, le cours Initiation à la comptabilité offert au collège Édouard-Montpetit présente un faible taux de réussite, le niveau d'intégration de certaines connaissances de ce cours est insuffisant pour plusieurs élèves et des désavantages découlent du fait qu'il n'est plus offert en laboratoire informatique depuis 2009. L'objectif général de cette recherche est de favoriser l'intégration des connaissances relatives à l'équation comptable de base et à la production des états financiers de l'entreprise commerciale par des élèves de Techniques administratives ayant ou percevant avoir des difficultés de traitement de l'information et de mémoire, d'attention, de lecture/écriture ou des fonctions exécutives à l'aide de matériel pédagogique mis en ligne. Une recension des écrits a permis, dans un premier temps, d'identifier les processus cognitifs sollicités dans l'apprentissage des différents types de connaissances dont le niveau d'intégration de plusieurs élèves est insuffisant, de même que de cerner le rôle et l'interdépendance des fonctions cognitives à l'étude. Ensuite, des moyens qui permettent de compenser des faiblesses relatives au traitement de l'information, aux processus mnésiques et attentionnels, de même qu'au niveau de certaines habiletés langagières et des fonctions exécutives ont été circonscrits. Une stratégie visant à favoriser les apprentissages d'élèves ayant, notamment, des troubles d'apprentissage a par la suite été identifiée, de même que les caractéristiques attendues d'une plateforme informatique afin qu'elle soit aidante pour des élèves ayant des difficultés cognitives. Les composantes du cadre conceptuel ont été intégrées au matériel pédagogique développé et mis en ligne. Ensuite, le matériel a fait l'objet d'une expérimentation et d'une évaluation auprès de trois catégories de participantes et de participants. Une posture épistémologique interprétative a été privilégiée pour cette recherche développement. Une approche mixte à prédominance qualitative a été utilisée. Ainsi, les outils de collecte de données qui ont été choisis visaient à comprendre le regard que posaient ces trois catégories de participantes et de participants à l'étude sur le matériel pédagogique développé et mis en ligne, plutôt que de mesurer une possible généralisation des résultats obtenus. Les catégories de personnes qui ont expérimenté et évalué le matériel sont formées de deux groupes d'élèves inscrits au cours Initiation à la comptabilité à la session d'automne 2010, de trois des cinq élèves de Techniques administratives ayant présenté un diagnostic de trouble d'apprentissage ou de déficit d'attention auprès des autorités du collège et d'une experte en services adaptés. L'analyse et l'interprétation des résultats a permis de constater que pour chacune des catégories de participantes et de participants à l'étude, le matériel pédagogique atteignait l'objectif général visé. Ainsi, une perception de légère amélioration de chacune des connaissances établies dans l'objectif général de recherche a été notée. De plus, les principales composantes du cadre conceptuel semblent atteindre leurs visées respectives. Cependant, plusieurs façons d'améliorer le matériel pédagogique ont été relevées par les personnes qui l'ont évalué. Parmi celles-ci, nous retrouvons le développement de plus d'autoévaluations, l'amélioration du nombre et de la précision des consignes d'utilisation du matériel, l'affinement des tables des matières et des points de repère visuels, de même que l'accroissement du nombre de sens sollicités lors de l'utilisation du matériel pédagogique. Une piste de recherche future pourrait être d'améliorer ce matériel pédagogique mis en ligne en y intégrant les suggestions formulées par les participantes et les participants à la présente étude, de même qu'en ajoutant au cadre conceptuel de nouvelles connaissances relatives aux neurosciences. Ensuite, il serait possible de procéder à une nouvelle expérimentation, s'échelonnant sur une plus grande période de temps, afin d'établir si les résultats obtenus peuvent être transférés à d'autres contextes d'apprentissage.

Celiac disease in children from Madeira island and its prevalence in first degree relatives

Context - It is well recognized that celiac disease is an immune-mediated systemic disorder highly prevalent among relatives of celiac patients. Objectives - The aim of this study is to determine the prevalence of celiac disease in a group of first degree relatives of celiac children, and to access the frequency of human leukocyte antigen HLA-DQ2 and DQ8 in celiac disease patients and their affected relatives. Methods - A survey was conducted of 39 children with celiac disease with follow-up in the Pediatric outpatient’s clinic of Dr. Nélio Mendonça Hospital, in Madeira Island, Portugal. Were invited 110 first degree relatives to undergo serological screen for celiac disease with IgA antibody to human recombinant tissue transglutaminase (IgA-TGG) quantification. In all seropositive relatives, small intestinal biopsy and HLA typing was recommended. Results - HLA- typing was performed in 38 celiac patients, 28/74% DQ2 positive, 1/2% DQ8 positive and 9/24% incomplete DQ2. Positive IgA-TGG was found in five out of the 95 relatives, and CD was diagnosed in three of them. Three relatives had the presence of HLA-DQ2, two were DQ2 incomplete (DQB1*02). Conclusion - The prevalence of celiac disease among first degree celiac patients´ relatives was 3.1%, 4.5 times higher than the general Portuguese population (0,7%) witch reinforces the need of extensive diagnostic screening in this specific group. HLA-DQ2 typing may be a tool in the diagnostic approach.

Exploring mediterranean durum wheat wild relatives and elite diversity panel for future breeding

Durum wheat (Triticum durum) is an important crop that has been used for millennia for human consumption, and modern breeding can take advantage of the wide variability useful for the adaptation to new challenges. Novel beneficial alleles can be found in wild relatives and landraces thus enhancing crop adaptation to many biotic and abiotic stresses. This dissertation considers the source of variability from both before and after wheat domestication, that caused a loss of potentially useful alleles. Chapter 1. is the thesis introduction, which outlines the importance of wheat in the world, providing an historical overview of the domestication, the evolution mechanisms that led to the current forms of durum wheat and the use of wild relatives as a source of germplasm for future breeding programs is crucial. Moreover, the emergence of Z. tritici has been considered as the main pathogen of wheat since it contains extremely high levels of genetic variability and is thus difficult to control. Chapter 2. Considers the contribution of the phenotypic diversity of 242 accessions of Aegilops tauschii from the Open Wild Wheat Consortium, involved in wheat domestication, provided with whole-genome resequencing. The accessions were phenotyped both in the field and in controlled conditions and A k-mer-based GWAS was performed to identify genomic regions involved in useful traits. Chapter 3. Describes the genetic basis of resistance to Z. tritici in a durum wheat elite diversity panel representative of the germplasm bred in Mediterranean. Quantitative trait loci (QTL) analysis results revealed several loci involved in the STB response that were found in several chromosome regions with a high infection rate. The genomic regions associated with STB resistance identified in this study could be of interest for marker assisted selection (MAS) in durum wheat breeding programs.

Longitudinal Analysis Of Hippocampal T2 Relaxometry In Fmtle.

To investigate the degree of T2 relaxometry changes over time in groups of patients with familial mesial temporal lobe epilepsy (FMTLE) and asymptomatic relatives. We conducted both cross-sectional and longitudinal analyses of T2 relaxometry with Aftervoxel, an in-house software for medical image visualization. The cross-sectional study included 35 subjects (26 with FMTLE and 9 asymptomatic relatives) and 40 controls; the longitudinal study was composed of 30 subjects (21 with FMTLE and 9 asymptomatic relatives; the mean time interval of MRIs was 4.4 ± 1.5 years) and 16 controls. To increase the size of our groups of patients and relatives, we combined data acquired in 2 scanners (2T and 3T) and obtained z-scores using their respective controls. General linear model on SPSS21® was used for statistical analysis. In the cross-sectional analysis, elevated T2 relaxometry was identified for subjects with seizures and intermediate values for asymptomatic relatives compared to controls. Subjects with MRI signs of hippocampal sclerosis presented elevated T2 relaxometry in the ipsilateral hippocampus, while patients and asymptomatic relatives with normal MRI presented elevated T2 values in the right hippocampus. The longitudinal analysis revealed a significant increase in T2 relaxometry for the ipsilateral hippocampus exclusively in patients with seizures. The longitudinal increase of T2 signal in patients with seizures suggests the existence of an interaction between ongoing seizures and the underlying pathology, causing progressive damage to the hippocampus. The identification of elevated T2 relaxometry in asymptomatic relatives and in patients with normal MRI suggests that genetic factors may be involved in the development of some mild hippocampal abnormalities in FMTLE.

The G209A mutation in the alpha-synuclein gene in Brazilian families with Parkinson's disease

A missense G209A mutation of the alpha-synuclein gene was recently described in a large Contursi kindred with Parkinson's disease (PD). The objective of this study is to determine if the mutation G209A of the alpha-synuclein gene was present in 10 Brazilian families with PD. PD patients were recruited from movement disorders clinics of Brazil. A family history with two or more affected in relatives was the inclusion criterion for this study. The alpha-synuclein G209A mutation assay was made using polymerase chain reaction and the restriction enzyme Tsp45I. Ten patients from 10 unrelated families were studied. The mean age of PD onset was 42.7 years old. We did not find the G209A mutation in our 10 families with PD. Our results suggest that alpha-synuclein mutation G209A is uncommon in Brazilian PD families.

Machado-Joseph disease versus hereditary spastic paraplegia: case report

Machado-Joseph disease (MJD) is the most common autosomal dominant spinocerebellar ataxia and presents great phenotypic variability. MJD presenting with spastic paraparesis was recently described in Japanese patients. We report the case of 41-year-old woman with the phenotype of complicated hereditary spastic paraplegia. Her father died at the age of 56 years due to an undiagnosed progressive neurological disease that presented parkinsonism. She had an expanded allele with 66 CAG repeats and a normal allele with 22 repeats in the gene of MJD. MJD should be considered in the differential diagnosis of autosomal dominant complicated HSP. A patient with the phenotype of complicated HSP and relatives with other clinical features of a neurodegenerative disease should raise the suspicion of MJD.

As relativas que são fáceis na aquisição do português brasileiro

The acquisition of Portuguese by two Brazilian children (aged 2;0 -5;0) is discussed in an attempt to describe and explain the first relative clauses produced in naturalistic, observational studies, according to the framework of generative syntax theory. The results show that at around 3;0: a) the child starts to deal with relative clauses as modifiers of N; b) cleft sentences appear before relative clauses, and c) the first relatives confirm the prevalence of the vernacular strategy of relativization in Brazilian Portuguese identified by other studies based on adult data.

Cromomicose cerebral: registro de um caso

A case of brain abscess and meningitis due to pigmented fungi is reported. The patient was a 59-year-old white male, who had enjoyed excellent health until October 1977, when he developed headache, later accompanied by paresthesias and weakness in the left-sided extremities. These symptoms worsened progressively and in November of that year he had to quit his job. From February 1978 on he became inactive and anorexic. Intense continuous headache was associated with frequent episodes of vomiting. He gradually became tor-porous, and according to his relatives, suffered from visual and possibly auditory deficiency. On examination, he was malnourished and dehydrated, with decubitus ulcers. Temperature was 38,5°C. A left-sided spastic hemiplegia and prominent meningorradicular signs were noted. The CSF was examined six times between May 17th and June 1st and showed variable hypercytosis (143 to 4,437 leucocytes/ cu mm) with predominance of neutrophils (up tp 95%), low glucose and high protein concentrations. No microorganisms were identified. Electroencephalographic study disclosed a low background activity especially in left temporal areas. Despite supportive care and antibiotic therapy he lapsed into coma. Carotid angiography was normal on June 1st. He remained in deep coma until his death on June 6th, 1978. Necropsy was limited to the brain, which weighed 1,550 g after fixation and showed diffuse intense edema and hyperemia. On coronal sectioning an encapsulated abscess was found in the right basal ganglia, which also involved the internal capsule, and measured 1.5 cm in diameter. Microscopical examination disclosed large numbers of brownish fungi, appearing both as oval yeasts and as septate hyphae in the thick fibrous capsule and in the necrotic content of the abscess. The same organisms were demonstrated in moderate numbers in the leptomeninges of the medulla oblongata and , less frequently, of the hippo-campal region and cerebellum.
