Evaluation Of An In-house Specific Immunoglobulin G (igg) Avidity Elisa For Distinguishing Recent Primary From Long-term Human Cytomegalovirus (hcmv) Infection.

This article describes the standardization and evaluation of an in-house specific IgG avidity ELISA for distinguishing recent primary from long-term human cytomegalovirus (HCMV) infection. The test was standardized with the commercial kit ETI-CYTOK G Plus (Sorin Biomedica, Italy) using 8 M urea in phosphate-buffered saline to dissociate low-avidity antibodies after the antigen-antibody interaction. The performance of the in-house assay was compared to that of the commercial automated VIDAS CMV IgG avidity test (bioM rieux, France). Forty-nine sera, 24 from patients with a recent primary HCMV infection and 25 from patients with a long-term HCMV infection and a sustained persistence of specific IgM antibodies, were tested. Similar results were obtained with the two avidity methods. All 24 sera from patients with recently acquired infection had avidity indices compatible with acute HCMV infection by the VIDAS method, whereas with the in-house method, one serum sample had an equivocal result. In the 25 sera from patients with long-term infection, identical results were obtained with the two methods, with only one serum sample having an incompatible value. These findings suggest that our in-house avidity test could be a potentially useful tool for the immunodiagnosis of HCMV infection.45323-

Avaliação de um teste de avidez imunoenzimático para o citomegalovírus humano (ELISA-HCMV) para distinguir a infecção primária recente da infecção de longa duração

O teste foi padronizado com o kit comercial ETI-CYTOK G Plus (Sorin Biomedica, Itália), utilizando uréia 8 M para a dissociação dos anticorpos de baixa avidez. A performance do teste ELISA-HCMV foi comparada com a do teste de avidez comercial automatizado VIDAS CMV IgG (bioMérieux, França), utilizando 24 soros de pacientes com infecção primária recente e 25 soros de pacientes com infecção de longa duração apresentando persistência de anticorpos específicos IgM. Resultados similares foram obtidos com os dois métodos de avidez. Todos os 24 soros de pacientes com infecção recentemente adquirida apresentaram índices de avidez compatíveis com infecção aguda pelo HCMV utilizando o teste VIDAS CMV IgG, enquanto que um dos soros apresentou resultado duvidoso no teste ELISA-HCMV. Os 25 soros de pacientes com infecção de longa duração apresentaram resultados idênticos com os dois métodos, com apenas um dos soros apresentando um valor não compatível. Estes resultados sugerem que o teste de avidez descrito pode ser potencialmente útil para o imunodiagnóstico da infecção pelo HCMV

Growing healthy is fun! A co-creation nutrition intervention to children aged 3-6 years

In order to promote healthier eating habits and consequently lower obesity levels, that it is important for children to have knowledge of diet and nutrition. Objectives: Increase nutritional knowledge about healthy eating and Portuguese food wheel in children aged 3-6years. Methods: Our group developed the Growing Healthy is Fun! to 3-6 years old children, at the Kindergarten of Obra Kolping. Several funny activities were planned, in order to instill knowledge about healthy eating and Portuguese food wheel, leading to best eating practices and adequate nutritional status. Structured interviews were conducted with the children pre and post the intervention for all children that parents or guardian delivered a written informed consent. Results: At pre intervention, the percentages of children that considered the example food as healthy food are: 100% for apple, beans, carrots and unflavored milk; 57.1% for fish; 28.6% for chocolate and cake. At post intervention the results are: 100% for apple, beans, carrots and unflavored milk; 85,7% for fish; and 0% for chocolate, cake and pizza. About Portuguese food wheel knowledge, at pre intervention, all children indicated cauliflower and banana, 71.4% considered olive oil and plain milk, 42.9% considered cake, and 28.7% considered egg and candy as foods belonging to the wheel. In post intervention, 100% of children considered egg, olive oil, cauliflower and bananas as food belonging to the wheel and 71.4% of them considered milk as belonging to the food wheel. Chocolate, candies, hamburger and cake were not classified as part of the food wheel.info:eu-repo/semantics/publishedVersio

Intellectual functioning in pediatric patients with epilepsy: a comparison of medically controlled, medically uncontrolled and surgically controlled children

OBJETIVO: Comparar o quociente intelectual (QI) em três grupos de crianças com epilepsia: 1) controlados com medicação, 2) não controlados com medicação e 3) controlados com cirurgia. MÉTODOS: Noventa e oito pacientes pediátricos, com idades entre 6 e 12 anos, foram selecionados de dezembro de 2007 a julho de 2008. A Escala de Inteligência Wechsler para Crianças - terceira edição (WISC-III) foi utilizada para a avaliação neuropsicológica dos pacientes. Os resultados foram relacionados com a síndrome epiléptica, a etiologia da epilepsia, o tratamento medicamentoso, a idade do paciente no início da epilepsia e a duração da epilepsia. RESULTADOS: Os escores da WISC foram significativamente melhores no grupo controlado com medicação quando comparados aos do grupo não controlado com medicação. O grupo controlado com medicação obteve um desempenho significativamente melhor na maioria dos subtestes da WISC quando comparado ao grupo não controlado com medicação: vocabulário, aritmética, compreensão, memória de dígitos, completar figuras, arranjo de figuras e cubos. Um número significativamente maior de pacientes com epilepsia idiopática e uso de monoterapia foi observado no grupo controlado com medicação quando comparado ao grupo não controlado. O grupo controlado com cirurgia não apresentou diferença significativa no desempenho do QI quando comparado ao grupo controlado com medicação. CONCLUSÕES: As crianças com um bom controle de crises tiveram um melhor desempenho no QI geral, verbal e de execução quando comparadas às crianças com epilepsia refratária. Esses resultados podem ser influenciados por fatores clínicos como o uso de monoterapia, o tipo de droga antiepiléptica utilizada, a síndrome epiléptica e a etiologia da epilepsia. A cirurgia de epilepsia pode causar um impacto positivo no desempenho cognitivo das crianças que ficaram livres de crises após o procedimento cirúrgico.OBJECTIVE: To compare the intellectual coefficient (IQ) of three groups of children with epilepsy: 1) medically controlled, 2) medically uncontrolled and 3) surgically controlled. METHODS: From December 2007 until July 2008, 98 pediatric patients were selected, with an age range between 6 and 12 years. Neuropsychological assessment included the Wechsler Intelligence Scale for Children - third edition (WISC-III). Results are related to epileptic syndrome, etiology of epilepsy, drug therapy, age at epilepsy onset and epilepsy duration. RESULTS: WISC scores were significantly better in the medically controlled group when compared to the medically uncontrolled group. The medically controlled group performed significantly better in the majority of the WISC subtests when compared to the medically uncontrolled group: vocabulary, arithmetic, comprehension, digit span, picture completion, picture arrangement, and block design. A significantly higher number of idiopathic epilepsy and monotherapy cases was observed in the medically controlled group when compared to the medically uncontrolled group. Surgically controlled children had no significant differences in IQ performance when compared to medically controlled children. CONCLUSIONS: Children with good seizure control have higher general, verbal and performed intelligence when compared to children with refractory epilepsy. These results may be influenced by clinical factors such as use of monotherapy, drug type and epileptic syndrome and etiology. Epilepsy surgery can have a positive impact on cognitive performance of children who were free of seizures after surgery

Perilipin regulates the thermogenic actions of norepinephrine in brown adipose tissue

In response to cold, norepinephrine (NE)-induced triacylglycerol hydrolysis (lipolysis) in adipocytes of brown adipose tissue (BAT) provides fatty acid substrates to mitochondria for heat generation (adaptive thermogenesis). NE-induced lipolysis is mediated by protein kinase A (PKA)-dependent phosphorylation of perilipin, a lipid droplet-associated protein that is the major regulator of lipolysis. We investigated the role of perilipin PKA phosphorylation in BAT NE-stimulated thermogenesis using a novel mouse model in which a mutant form of perilipin, lacking all six PKA phosphorylation sites, is expressed in adipocytes of perilipin knockout (Peri KO) mice. Here, we show that despite a normal mitochondrial respiratory capacity, NE-induced lipolysis is abrogated in the interscapular brown adipose tissue (IBAT) of these mice. This lipolytic constraint is accompanied by a dramatic blunting (∼70%) of the in vivo thermal response to NE. Thus, in the presence of perilipin, PKA-mediated perilipin phosphorylation is essential for NE-dependent lipolysis and full adaptive thermogenesis in BAT. In IBAT of Peri KO mice, increased basal lipolysis attributable to the absence of perilipin is sufficient to support a rapid NE-stimulated temperature increase (∼3.0°C) comparable to that in wild-type mice. This observation suggests that one or more NE-dependent mechanism downstream of perilipin phosphorylation is required to initiate and/or sustain the IBAT thermal response

Mortality of Patients with Hematological Malignancy after Admission to the Intensive Care Unit

Background: The admission of patients with malignancies to an intensive care unit (ICU) still remains a matter of substantial controversy. The identification of factors that potentially influence the patient outcome can help ICU professionals make appropriate decisions. Patients and Methods: 90 adult patients with hematological malignancy (leukemia 47.8%, high-grade lymphoma 50%) admitted to the ICU were analyzed retrospectively in this single-center study considering numerous variables with regard to their influence on ICU and day-100 mortality. Results: The median simplified acute physiology score (SAPS) II at ICU admission was 55 (ICU survivors 47 vs. 60.5 for non-survivors). The overall ICU mortality rate was 45.6%. With multivariate regression analysis, patients admitted with sepsis and acute respiratory failure had a significantly increased ICU mortality (sepsis odds ratio (OR) 9.12, 95% confidence interval (CI) 1.1-99.7, p = 0.04; respiratory failure OR 13.72, 95% CI 1.39-136.15, p = 0.025). Additional factors associated with an increased mortality were: high doses of catecholamines (ICU: OR 7.37, p = 0.005; day 100: hazard ratio (HR) 2.96, p < 0.0001), renal replacement therapy (day 100: HR 1.93, p = 0.026), and high SAPS II (ICU: HR 1.05, p = 0.038; day 100: HR 1.2, p = 0.027). Conclusion: The decision for or against ICU admission of patients with hematological diseases should become increasingly independent of the underlying malignant disease
