Enfermedad pulmonar intersticial en Esclerosis Sistémica: diferencia en la presentación clínica y evolución clínica y evolución entre pacientes con anticuerpos Scl-70 frente PM-Scl

La esclerosis sistémica (ES) es una enfermedad autoinmune multisistémica que afecta de forma variable a diferentes órganos. En el pulmón produce la enfermedad pulmonar intersticial difusa (EPID), cuyo pronóstico difiere según el autoanticuerpo asociado. Se estudiaron las características clínicas y espirométricas de 63 pacientes diagnosticados de ES y EPID, con positividad para anti-Scl-70 o anti-PM-Scl. En el grupo anti-Scl-70 se documentó mayor prevalencia de úlceras digitales y afección gastrointestinal, con mayor pérdida de capacidad vital forzada (CVF) al final del seguimiento y mayor proporción de patrón restrictivo grave. El grupo anti-PM-Scl presentó mayor miopatía inflamatoria y mejor evolución espirométrica.

Registros noticiosos sobre a escola profissional de enfermeiros e enfermeiras na revista "O Brazil-Médico", 1890-1922

Estudo histórico descritivo com o objetivo de identificar registros noticiosos sobre a Escola de Enfermagem Alfredo Pinto, antiga Escola Profissional de Enfermeiros e Enfermeiras (EPEE), veiculadas na revista mencionada no período referido. A metodologia utilizada foi a análise documental como técnica de pesquisa. A revista foi publicada de forma ininterrupta durante esse período de 32 anos e 1.632 exemplares foram consultados. Foram encontradas 16 notícias alusivas à EPEE, ao Hospital Nacional de Alienados, à Enfermagem e Cursos de Enfermagem. Desse total, apenas cinco notícias referiam-se diretamente à EPEE. Analisando seu conteúdo despontam duas idéias fundamentais: 1) a EPEE teve duas inaugurações, em 1897 e 1906, o que ratifica o Decreto de criação em 27/09/1890; e, 2) a dificuldade de operacionalização da EPEE, àquela época, em virtude da baixa qualificação dos candidatos a alunos.

Transtorno mental: dificuldades enfrentadas pela família

Utilizando uma metodologia qualitativa (entrevistas abertas, desenho-estória e análise temática) identificamos e analisamos 4 categorias (descompasso temporal, culpa, conflitos e perdas) presentes no discurso de mães (e uma irmã) de pacientes psiquiátricos do Núcleo de Atenção Psicossocial (NAPS) de Ribeirão Preto/SP, e avaliamos sua importância conforme o objetivo de se entender a dinâmica da relação entre serviço de saúde mental, paciente psiquiátrico e sua família.

Entre desafios e possibilidades: estratégias para ensinar a cuidar em enfermagem do adolescente com câncer

Trata-se de um relato de experiência, que tem como objetivo apresentar reflexões acerca das experiências vivenciadas junto aos alunos do Curso de Graduação em Enfermagem da Escola de Enfermagem Alfredo Pinto da Universidade Federal do Estado do Rio de Janeiro (UNIRIO). No cotidiano da prática de ensino, os alunos se deparam com adolescentes acometidos pelos distúrbios onco-hematológicos. Constatou-se que, para os estudantes, era um desafio aprender a cuidar do adolescente em um momento de adoecimento pelo câncer, doença que traz importantes significados no imaginário social. Como estratégia para a aprendizagem, optou-se por uma atividade denominada oficina de idéias, a qual possibilitava aos alunos que expressassem seus sentimentos, idéias (pré) concebidas e expectativas acerca do cuidar do adolescente com câncer. Como resultados, evidenciou-se um singular momento de reflexão/sensibilização que resulta em um preparo e um reconhecimento das peculiaridades desse grupo e atitude de aproximação para o cuidar no espaço hospitalar.

A variant in the gene FUT9 is associated with susceptibility to placental malaria infection

Malaria in pregnancy forms a substantial part of the worldwide burden of malaria, with an estimated annual death toll of up to 200,000 infants, as well as increased maternal morbidity and mortality. Studies of genetic susceptibility to malaria have so far focused on infant malaria, with only a few studies investigating the genetic basis of placental malaria, focusing only on a limited number of candidate genes. The aim of this study therefore was to identify novel host genetic factors involved in placental malaria infection. To this end we carried out a nested case-control study on 180 Mozambican pregnant women with placental malaria infection, and 180 controls within an intervention trial of malaria prevention. We genotyped 880 SNPs in a set of 64 functionally related genes involved in glycosylation and innate immunity. A SNP located in the gene FUT9, rs3811070, was significantly associated with placental malaria infection (OR = 2.31, permutation p-value = 0.028). Haplotypic analysis revealed a similarly strong association of a common haplotype of four SNPs including rs3811070. FUT9 codes for a fucosyl-transferase that is catalyzing the last step in the biosynthesis of the Lewis-x antigen, which forms part of the Lewis blood group-related antigens. These results therefore suggest an involvement of this antigen in the pathogenesis of placental malaria infection.

Evolutionary analysis of genes of two pathways involved in placental malaria infection

Placental malaria is a special form of malaria that causes up to 200,000 maternal and infant deaths every year. Previous studies show that two receptor molecules, hyaluronic acid and chondroitin sulphate A, are mediating the adhesion of parasite-infected erythrocytes in the placenta of patients, which is believed to be a key step in the pathogenesis of the disease. In this study, we aimed at identifying sites of malaria-induced adaptation by scanning for signatures of natural selection in 24 genes in the complete biosynthesis pathway of these two receptor molecules. We analyzed a total of 24 Mb of publicly available polymorphism data from the International HapMap project for three human populations with European, Asian and African ancestry, with the African population from a region of presently and historically high malaria prevalence. Using the methods based on allele frequency distributions, genetic differentiation between populations, and on long-range haplotype structure, we found only limited evidence for malaria-induced genetic adaptation in this set of genes in the African population; however, we identified one candidate gene with clear evidence of selection in the Asian population. Although historical exposure to malaria in this population cannot be ruled out, we speculate that it might be caused by other pathogens, as there is growing evidence that these molecules are important receptors in a variety of host-pathogen interactions. We propose to use the present methods in a systematic way to help identify candidate regions under positive selection as a consequence of malaria.

A targeted association study of immunity genes and networks suggests novel associations with placental malaria infection

A large proportion of the death toll associated with malaria is a consequence of malaria infection during pregnancy, causing up to 200,000 infant deaths annually. We previously published the first extensive genetic association study of placental malaria infection, and here we extend this analysis considerably, investigating genetic variation in over 9,000 SNPs in more than 1,000 genes involved in immunity and inflammation for their involvement in susceptibility to placental malaria infection. We applied a new approach incorporating results from both single gene analysis as well as gene-gene interactionson a protein-protein interaction network. We found suggestive associations of variants in the gene KLRK1 in the single geneanalysis, as well as evidence for associations of multiple members of the IL-7/IL-7R signalling cascade in the combined analysis. To our knowledge, this is the first large-scale genetic study on placental malaria infection to date, opening the door for follow-up studies trying to elucidate the genetic basis of this neglected form of malaria.

Comprehensive evaluation of the IEEE 802.15.4 MAC layer performance with retransmissions

Supported by IEEE 802.15.4 standardization activities, embedded networks have been gaining popularity in recent years. The focus of this paper is to quantify the behavior of key networking metrics of IEEE 802.15.4 beacon-enabled nodes under typical operating conditions, with the inclusion of packet retransmissions. We corrected and extended previous analyses by scrutinizing the assumptions on which the prevalent Markovian modeling is generally based. By means of a comparative study, we singled out which of the assumptions impact each of the performance metrics (throughput, delay, power consumption, collision probability, and packet-discard probability). In particular, we showed that - unlike what is usually assumed - the probability that a node senses the channel busy is not constant for all the stages of the backoff procedure and that these differences have a noticeable impact on backoff delay, packet-discard probability, and power consumption. Similarly, we showed that - again contrary to common assumption - the probability of obtaining transmission access to the channel depends on the number of nodes that is simultaneously sensing it. We evidenced that ignoring this dependence has a significant impact on the calculated values of throughput and collision probability. Circumventing these and other assumptions, we rigorously characterize, through a semianalytical approach, the key metrics in a beacon-enabled IEEE 802.15.4 system with retransmissions.

The relation of body mass index and abdominal adiposity with dyslipidemia in 27 general populations of the WHO MONICA Project.

The association between adiposity measures and dyslipidemia has seldom been assessed in a multipopulational setting. 27 populations from Europe, Australia, New Zealand and Canada (WHO MONICA project) using health surveys conducted between 1990 and 1997 in adults aged 35-64 years (n = 40,480). Dyslipidemia was defined as the total/HDL cholesterol ratio >6 (men) and >5 (women). Overall prevalence of dyslipidemia was 25% in men and 23% in women. Logistic regression showed that dyslipidemia was strongly associated with body mass index (BMI) in men and with waist circumference (WC) in women, after adjusting for region, age and smoking. Among normal-weight men and women (BMI<25 kg/m(2)), an increase in the odds for being dyslipidemic was observed between lowest and highest WC quartiles (OR = 3.6, p < 0.001). Among obese men (BMI ≥ 30), the corresponding increase was smaller (OR = 1.2, p = 0.036). A similar weakening was observed among women. Classification tree analysis was performed to assign subjects into classes of risk for dyslipidemia. BMI thresholds (25.4 and 29.2 kg/m(2)) in men and WC thresholds (81.7 and 92.6 cm) in women came out at first stages. High WC (>84.8 cm) in normal-weight men, menopause in women and regular smoking further defined subgroups at increased risk. standard categories of BMI and WC, or their combinations, do not lead to optimal risk stratification for dyslipidemia in middle-age adults. Sex-specific adaptations are necessary, in particular by taking into account abdominal obesity in normal-weight men, post-menopausal age in women and regular smoking in both sexes.
