Detection of cognitive impairment with the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) in adolescents with psychotic symptomatology.

Cognitive impairment has been identified in the early phase of schizophrenia spectrum disorders, and is a major contributor to disease-related disability. While screening tools assessing cognitive impairment have been validated for adult schizophrenic populations, there is a need for brief, easily administered, standardized instruments that provide clinically relevant information for adolescents. This study examines the utility of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) in identifying and quantifying neurocognitive impairment in adolescents with schizophrenia spectrum disorders and other serious psychiatric illnesses. 112 adolescents, including 32 healthy subjects and 80 patients, were administered the RBANS. Patients with psychotic disorders demonstrated significant impairment on the RBANS total score compared to patients with other disorders and healthy controls, but this impairment appeared somewhat less severe than is typically reported for in adult patients with schizophrenia on this measure. The RBANS appears to be sensitive in the detection of neurocognitive impairment in a psychiatric population of adolescents with psychotic symptomatology, and may therefore have utility as a clinical screening instrument and/or neurocognitive outcome measure in this population.

Host nutritional status as a contributory factor to the remodeling of schistosomal hepatic fibrosis

Weaning Swiss mice were percutaneously infected with 30 cercariae of Schistosoma mansoni and submitted to a shifting either from a deficient to a balanced diet or vice-versa, for 24 weeks. The nutritional status was weekly evaluated by measurements of growth curves and food intake. Hepatic fibrosis and periovular granulomas were studied by histological, morphometric and biochemical methods. All mice fed on a deficient diet failed to develop periportal "pipestem" fibrosis after chronic infection. An unexpected finding was the absence of pipestem fibrosis in mice on normal diet, probably related to the sample size. The lower values for nutritional parameters were mainly due to the deficient diet, rather than to infection. Liver/body weight ratio was higher in "early undernutrition" group, after shifting to the balanced diet. Volume density and numerical density of egg granulomas reached lowest values in undernourished animals. The amount of collagen was reduced in undernourished mice, attaining higher concentrations in well-fed controls and in "late undernutrition" (balanced diet shifted to a deficient one), where collagen deposition appeared increased in granulomas. That finding suggested interference with collagen degradation and resorption in "late" undernourished animals. Thus, host nutritional status plays a role in connective tissue changes of hepatic schistosomiasis in mice.

Not in Education, Employment, or Training status among young Swiss men. Longitudinal associations with mental health and substance use.

PURPOSE: Not in Education, Employment, or Training (NEET) youth are youth disengaged from major social institutions and constitute a worrying concern. However, little is known about this subgroup of vulnerable youth. This study aimed to examine if NEET youth differ from other contemporaries in terms of personality, mental health, and substance use and to provide longitudinal examination of NEET status, testing its stability and prospective pathways with mental health and substance use. METHODS: As part of the Cohort Study on Substance Use Risk Factors, 4,758 young Swiss men in their early 20s answered questions concerning their current professional and educational status, personality, substance use, and symptomatology related to mental health. Descriptive statistics, generalized linear models for cross-sectional comparisons, and cross-lagged panel models for longitudinal associations were computed. RESULTS: NEET youth were 6.1% at baseline and 7.4% at follow-up with 1.4% being NEET at both time points. Comparisons between NEET and non-NEET youth showed significant differences in substance use and depressive symptoms only. Longitudinal associations showed that previous mental health, cannabis use, and daily smoking increased the likelihood of being NEET. Reverse causal paths were nonsignificant. CONCLUSIONS: NEET status seemed to be unlikely and transient among young Swiss men, associated with differences in mental health and substance use but not in personality. Causal paths presented NEET status as a consequence of mental health and substance use rather than a cause. Additionally, this study confirmed that cannabis use and daily smoking are public health problems. Prevention programs need to focus on these vulnerable youth to avoid them being disengaged.

Stroke initial severity and outcome relative to insurance status in a universal health care system in Switzerland

Contexte et but de l'étude :Le statut socio-économique est suspecté d'avoir une influence significative sur l'incidence des attaques cérébrales (AVC), sur les facteurs de risque cardio-vasculaire, ainsi que sur le pronostic. L'influence de ce statut socio-économique sur la sévérité de l'AVC et sur les mécanismes physiopathologiques sous-jacents est moins connue.Méthode :Sur une période de 4 ans, nous avons collecté de manière prospective (dans un registre) des données concernant tous les patients avec AVC aigus admis à l'Unité Cérébrovasculaire du CHUV. Les données comprenaient le statut assécurologique du patient (assurance privée ou générale), les données démographiques, les facteurs de risque cérébrovasculaires, l'utilisation de traitements aigus de recanalisation vasculaire, le délai avant l'admission à l'hôpital, ainsi que la sévérité et le pronostic de l'AVC en phase aiguë, à 7 jours et à 3 mois des symptômes. Les patients avec assurance privée ont été comparés à ceux avec assurance générale.Résultats :Sur 1062 patients avec AVC, 203 avaient une assurance privée et 859 avaient une assurance générale. Il y a avait 585 hommes et 477 femmes. Les deux populations étaient similaires en âge. Les facteurs de risque cardio-vasculaire, la médication préventive, le délai d'arrivée à l'hôpital, l'incidence du taux de thrombolyse et l'étiologie de l'AVC ne différaient pas dans les deux populations. Le score de gravité de l'AVC en phase aiguë, mesuré par le NIHSS, était significativement plus élevé chez les patients avec assurance générale. Un pronostic favorable, mesuré par le score de Rankin modifié (mRS), était plus fréquemment obtenu à 7 jours et à 3 mois chez les patients avec assurance privée.Commentaires :Un statut socio-économique bas est associé à une incidence plus élevée de maladies cérébrovasculaires ainsi qu'à un plus mauvais pronostic, comme cela a été démontré dans différents pays. Il a été suspecté que l'accès à une prise en charge spécialisée en phase aiguë ou en rééducation soit différent selon le statut socio-économique. Comme la Suisse a un système de santé universel, avec une couverture assécurologique obligatoire pour chaque habitant, il y a là une occasion unique de comparer l'influence de l'aspect socio-économique sur la sévérité et le pronostic de l'AVC. De plus, les patients ont été admis dans la même Unité Cérébrovasculaire et pris en charge par la même équipe médicale.Conclusion et perspectives :Le lien entre le statut assécurologique et le statut socio-économique a déjà été prouvé par le passé dans d'autres pays. Nous avons mis en évidence une sévérité plus importante et un plus mauvais pronostic chez les patients avec assurance générale dans la population étudiée. L'étiologie de cette différence dans un système de santé à couverture universelle comme celui de la Suisse reste peu claire. Elle devrait être étudiée à plus grande échelle.

Epidemiology of leishmaniasis in Ecuador: current status of knowledge - A review

Although leishmaniasis is regarded as a significant health problem in Ecuador by the Ministry of Health, and the incidence has increased over the last years, an official map on the geographic distribution of disease and sand fly vectors or a control strategy do not exist yet. This article reviews the current situation based on published information to improve our knowledge and understand the epidemiological situation of leishmaniasis in Ecuador in order to help future research and to develop a national control strategy. The disease is endemic in most provinces throughout Pacific coastal region, Amazonian lowlands, and some inter-Andean valleys with a total 21,805 cases reported during 1990-2003. Whereas cutaneous leishmaniasis (CL) is found throughout Ecuador, mucocutaneous leishmaniasis (MCL) appears to be restricted to the Amazon region; one, parasitologically unconfirmed case of visceral form was reported in 1949. Most human infections are caused by Leishmania (Viannia) spp., which is distributed in the subtropical and tropical lowlands; infections due to L. (Leishmania) spp. are found in the Andean highlands and in the Pacific lowlands as well. The proven vectors are Lutzomyia trapidoi and Lu. ayacuchensis. Canis familiaris, Sciurus vulgaris, Potos flavus, and Tamandua tetradactyla have been found infected with Leishmania spp. It is estimated that around 3000-4500 people may be infected every year, and that 3.1 to 4.5 millions people are estimated to be at risk of contracting leishmaniasis.

A picture of health: A study of the health status and health promotion needs of homeless people in the west.

Homeless people have been identified as a group that experience inequality in health and a target group in relation to health promotion initiatives. In developing health promotion initiatives it is important to take account of the broader determinants of health and to address the physical, mental and social well-being of homeless people. The study aimed to identify the health status and health promotion needs of homeless people in the Western Health Board region.To gain an understanding of the health problems and health promotion needs of homeless people one to one interviews were carried out with homeless people and focus groups were carried out with service providers. Sixty five interviews were carried out with people currently accessing voluntary services in Galway and Mayo. Three focus groups were carried out with service providers from voluntary and statutory services.This resource was contributed by The National Documentation Centre on Drug Use.

Dietary and lifestyle interventions in the management of the metabolic syndrome: present status and future perspective.

OBJECTIVE: To review the mechanisms underlying the metabolic syndrome, or syndrome X, in humans, and to delineate dietary and environmental strategies for its prevention. DESIGN: Review of selected papers of the literature. RESULTS: Hyperinsulinemia and insulin resistance play a key role in the development of the metabolic syndrome. Strategies aimed at reducing insulin resistance may be effective in improving the metabolic syndrome. They include low saturated fat intake, consumption of low-glycemic-index foods, physical exercise and prevention of obesity. CONCLUSIONS: Future research, in particular the genetic basis of the metabolic syndrome and the interorgan interactions responsible for insulin resistance, is needed to improve therapeutic strategies for the metabolic syndrome.

Management of refractory status epilepticus in adults: still more questions than answers.

Refractory status epilepticus (RSE) is defined as status epilepticus that continues despite treatment with benzodiazepines and one antiepileptic drug. RSE should be treated promptly to prevent morbidity and mortality; however, scarce evidence is available to support the choice of specific treatments. Major independent outcome predictors are age (not modifiable) and cause (which should be actively targeted). Recent recommendations for adults suggest that the aggressiveness of treatment for RSE should be tailored to the clinical situation. To minimise intensive care unit-related complications, focal RSE without impairment of consciousness might initially be approached conservatively; conversely, early induction of pharmacological coma is advisable in generalised convulsive forms of the disorder. At this stage, midazolam, propofol, or barbiturates are the most commonly used drugs. Several other treatments, such as additional anaesthetics, other antiepileptic or immunomodulatory compounds, or non-pharmacological approaches (eg, electroconvulsive treatment or hypothermia), have been used in protracted RSE. Treatment lasting weeks or months can sometimes result in a good outcome, as in selected patients after encephalitis or autoimmune disorders. Well designed prospective studies of RSE are urgently needed.

Pacemakers and magnetic resonance imaging: Current status and survey in Switzerland.

Electromagnetic fields arising from magnetic resonance imaging (MRI) can cause various clinically relevant functional disturbances in patients with cardiac pacemakers. Consequently, an implanted pacemaker is generally considered a contraindication for an MRI scan. With approximately 60 million MRI scans performed worldwide per year, MRI may be indicated for an estimated majority of pacemaker patients during the lifetime of their pacemakers. The availability of MR conditional pacemakers with CE labelling is of particular advantage since they allow the safe use of pacemakers in MRI. In this article the current state of knowledge on pacemakers and MR imaging is discussed. We present the results of a survey conducted among Swiss radiologists to assess current practice in patients with pacemakers.

Clinical and pathological importance of vacA allele heterogeneity and cagA status in peptic ulcer disease in patients from North Brazil

We have examined the prevalence of gene cagA and vacA alleles in 129 patients, 69 with gastritis and 60 with peptic ulcer diseases from North Brazil and their relation with histopathological data. vacA and cagA genotype were determined by polymerase chain reaction. Hematoxylin-eosin staining was used for histological diagnosis. 96.6% of the patients were colonized by Helicobacter pylori strains harboring single vacA genotype (nont-mixed infection). Among them, 11.8% had subtype s1a, 67.8% had subtype s1b, and 17% subtype s2. In regard to the middle region analysis, m1 alleles were found in 75.4% and m2 in 21.2% of patients. The cagA gene was detected in 78% patients infected with H. pylori and was associated with the s1-m1 vacA genotype. The H. pylori strains, vacA s1b m1/cagA-positive, were associated with increased risk of peptic ulcer disease and higher amounts of lymphocytic and neutrophilic infiltrates and the presence of intestinal metaplasia. These findings show that cagA and vacA genotyping may have clinical relevance in Brazil.
