Mortalidade pós-neonatal no território brasileiro: uma revisão da literatura

O presente trabalho trata-se de revisão sistemática, referente ao período de 2004 a 2009, sobre o tema mortalidade pós-neonatal. Teve o objetivo de identificar como se colocam na literatura, as causas da morte e a relação com as condições socioeconômicas. Foram selecionados 27 artigos, 74,4% publicados em periódicos da área da Saúde Pública e 66,7%, de desenho do tipo ecológico. Quase a totalidade versava sobre grupos de causas e seus componentes (66,7%), seguidos pelo terço restante, sobre a identificação dos fatores determinantes dos óbitos. A região Sudeste produziu mais de 37% dos estudos. Na maioria dos municípios e estados brasileiros, a redução superou 50% no final da década de 1990. Dentre os grupos de causas de óbitos, predominou o grupamento diarreia-pneumonia, seguido pelas malformações congênitas. As condições de vida segundo indicadores socioeconômicos - moradia, saneamento básico, educação e acesso à saúde - foram determinantes para os maiores índices de mortalidade pós-neonatal por causas passíveis de redução.

Impact of a telenursing service on satisfaction and health outcomes of children with inflammatory rheumatic diseases and their families: a crossover randomized trial study protocol.

BACKGROUND: Pediatric rheumatic diseases have a significant impact on children's quality of life and family functioning. Disease control and management of the symptoms are important to minimize disability and pain. Specialist clinical nurses play a key role in supporting medical teams, recognizing poor disease control and the need for treatment changes, providing a resource to patients on treatment options and access to additional support and advice, and identifying best practices to achieve optimal outcomes for patients and their families. This highlights the importance of investigating follow-up telenursing (TN) consultations with experienced, specialist clinical nurses in rheumatology to provide this support to children and their families. METHODS/DESIGN: This randomized crossover, experimental longitudinal study will compare the effects of standard care against a novel telenursing consultation on children's and family outcomes. It will examine children below 16 years old, recently diagnosed with inflammatory rheumatic diseases, who attend the pediatric rheumatology outpatient clinic of a tertiary referral hospital in western Switzerland, and one of their parents. The telenursing consultation, at least once a month, by a qualified, experienced, specialist nurse in pediatric rheumatology will consist of providing affective support, health information, and aid to decision-making. Cox's Interaction Model of Client Health Behavior serves as the theoretical framework for this study. The primary outcome measure is satisfaction and this will be assessed using mixed methods (quantitative and qualitative data). Secondary outcome measures include disease activity, quality of life, adherence to treatment, use of the telenursing service, and cost. We plan to enroll 56 children. DISCUSSION: The telenursing consultation is designed to support parents and children/adolescents during the course of the disease with regular follow-up. This project is novel because it is based on a theoretical standardized intervention, yet it allows for individualized care. We expect this trial to confirm the importance of support by a clinical specialist nurse in improving outcomes for children and adolescents with inflammatory rheumatisms. TRIAL REGISTRATION: ClinicalTrial.gov identifier: NCT01511341 (December 1st, 2012).

Peroxisome proliferator-activated receptor beta/delta as a therapeutic target for metabolic diseases.

The peroxisome proliferator-activated receptor (PPAR) family comprises three distinct isotypes: PPARalpha, PPARbeta/delta and PPARgamma. PPARs are nuclear hormone receptors that mediate the effects of fatty acids and their derivatives at the transcriptional level. Until recently, the characterisation of the important role of PPARalpha in fatty acid oxidation and of PPARgamma in lipid storage contrasted with the sparse information concerning PPARbeta/delta. However, evidence is now emerging for a role of PPARbeta/delta in tissue repair and energy homeostasis. Experiments with tissue-specific overexpression of PPARbeta/delta or treatment of mice with selective PPARbeta/delta agonists demonstrated that activation of PPARbeta/delta in vivo increases lipid catabolism in skeletal muscle, heart and adipose tissue and improves the serum lipid profile and insulin sensitivity in several animal models. PPARbeta/delta activation also prevents the development of obesity and improves cholesterol homeostasis in obesity-prone mouse models. These new insights into PPARbeta/delta functions suggest that targeting PPARbeta/delta may be helpful for treating disorders associated with the metabolic syndrome. Although these perspectives are promising, several independent and contradictory reports raise concerns about the safety of PPARbeta/delta ligands with respect to tumourigenic activity in the gut. Thus, it appears that further exploration of PPARbeta/delta functions is necessary to better define its potential as a therapeutic target.

Maternal side-effects after multiple courses of antenatal corticosteroids (MACS): the three-month follow-up of women in the randomized controlled trial of MACS for preterm birth study.

OBJECTIVE: A single course of antenatal corticosteroids (ACS) is associated with a reduction in respiratory distress syndrome and neonatal death. Multiple Courses of Antenatal Corticosteroids Study (MACS), a study involving 1858 women, was a multicentre randomized placebo-controlled trial of multiple courses of ACS, given every 14 days until 33+6 weeks or birth, whichever came first. The primary outcome of the study, a composite of neonatal mortality and morbidity, was similar for the multiple ACS and placebo groups (12.9% vs. 12.5%), but infants exposed to multiple courses of ACS weighed less, were shorter, and had smaller head circumferences. Thus for women who remain at increased risk of preterm birth, multiple courses of ACS (every 14 days) are not recommended. Chronic use of corticosteroids is associated with numerous side effects including weight gain and depression. The aim of this postpartum assessment was to ascertain if multiple courses of ACS were associated with maternal side effects. METHODS: Three months postpartum, women who participated in MACS were asked to complete a structured questionnaire that asked about maternal side effects of corticosteroid use during MACS and included the Edinburgh Postnatal Depression Scale. Women were also asked to evaluate their study participation. RESULTS: Of the 1858 women randomized, 1712 (92.1%) completed the postpartum questionnaire. There were no significant differences in the risk of maternal side effects between the two groups. Large numbers of women met the criteria for postpartum depression (14.1% in the ACS vs. 16.0% in the placebo group). Most women (94.1%) responded that they would participate in the trial again. CONCLUSION: In pregnancy, corticosteroids are given to women for fetal lung maturation and for the treatment of various maternal diseases. In this international multicentre randomized controlled trial, multiple courses of ACS (every 14 days) were not associated with maternal side effects, and the majority of women responded that they would participate in such a study again.

Fatores determinantes da mortalidade neonatal em um município da Região Sul do Brasil

Pesquisa quantitativa do tipo ecológico cujo objetivo foi identificar os fatores de risco que determinaram o óbito neonatal no município de Londrina, Paraná, entre 2000 e 2009. Verificou-se que idade materna, escolaridade, renda familiar, ocupação, situação conjugal, tipo de parto e número de consultas pré-natais não se associaram ao óbito neonatal. Entretanto, o peso ao nascer, a idade gestacional, o índice de Apgar no 1º e 5º minutos e local do parto mostraram-se estatisticamente significativos. Mais de 73,0% dos recém-nascidos evoluíram para óbito no período neonatal precoce. A causa básica predominante foi a afecção perinatal (77,7%), sendo que 72,6% das mortes foram consideradas evitáveis e a maioria, reduzível por controle adequado da gravidez e do parto. Tais resultados reforçam a necessidade de investimentos na prevenção do parto prematuro com assistência antenatal e ao parto equitativa, acessível e integral entre os diferentes níveis de atenção à saúde materno-infantil.

Fatores associados à infecção pelo uso do cateter central de inserção periférica em Unidade de Terapia Intensiva Neonatal

Estudo epidemiológico, longitudinal e analítico, desenvolvido em um hospital de Minas Gerais, com o objetivo de analisar os fatores associados à infecção pelo uso do cateter central de inserção periférica em recém-nascidos internados em unidade de terapia intensiva. A coleta dos dados foi realizada por meio de uma ficha estruturada, preenchida pelos profissionais e verificada pelos pesquisadores. Foram estudados 291 cateteres inseridos em 233 recém-nascidos. Os fatores associados à retirada por suspeita de infecção foram: prematuridade, peso ao nascer até 1.500 gramas, cateter de poliuretano, localização não centralizada do cateter e tempo de uso superior a 30 dias. Após ajuste multivariado, permaneceram independentemente associados: peso inferior a 2.500 gramas na inserção, reparo e tempo de uso do cateter. Conclui-se que fatores relacionados à prática dos profissionais contribuíram para a retirada dos cateteres, sinalizando para a necessidade de intervenções que melhorem a segurança e a eficácia em seu uso.

Estudo descritivo, longitudinal e abordagem quantitativa, que objetivou analisar e discutir o processo do cateterismo venoso central nas Unidades de Terapia Intensiva neonatal e pediátrica; descrever as variáveis relacionadas à caracterização da população do estudo (unidade de internação, faixa etária e sexo) e descrever as variáveis relacionadas ao processo do cateterismo venoso central (tipo de cateter, motivo de indicação, número de lumens, sítio de inserção, profissional que realizou o procedimento, terapêutica medicamentosa infundida via cateter, motivo de retirada, tempo de permanência e as complicações mecânicas e infecciosas). A coleta de dados foi realizada em unidade de terapia intensiva neonatal e pediátrica, em 82 prontuários. As indicações dos cateteres foram, em sua maioria, para infusão medicamentosa prolongada e Nutrição Parenteral Total. A remoção foi indicada predominantemente por complicações mecânicas e infecciosas. Esse estudo viabilizou rever a prática assistencial para estabelecer o aprimoramento da assistência prestada à clientela neonatal e pediátrica.

Work in inflammatory and degenerative joint diseases

This article focuses on work disability and sick leave and their cost; it also discusses the value of vocational rehabilitation programmes in rheumatic conditions such as rheumatoid arthritis, ankylosing spondylitis, hip and knee osteoarthritis. It acknowledges the importance of work not only for the worker who has one of these diseases but also for the public purse. Much can be done to improve the health of the persons and reduce their disability and its impact in the workplace which will have an important effect on their and their family's quality of life. It is important that neither rehabilitation nor vocational rehabilitation are regarded as bolt-on activities after drug treatment but are seen as an integral part of effective management. Publications dealing with return to work are relatively common in rheumatoid arthritis, less common in ankylosing spondylitis and relatively rare in osteoarthritis. Vocational rehabilitation programmes should aim to facilitate job retention or, failing that, to improve the ability to return to work. The process must be started with in the health arena and it has to be recognised that slow or poor practice in the health service can jeopardise the patient's work potential

Human milk for neonatal pain relief during ophthalmoscopy

Ophthalmoscopy performed for the early diagnosis of retinopathy of prematurity (ROP) is painful for preterm infants, thus necessitating interventions for minimizing pain. The present study aimed to establish the effectiveness of human milk, compared with sucrose, for pain relief in premature infants subjected to ophthalmoscopy for the early diagnosis of ROP. This investigation was a pilot, quasi-experimental study conducted with 14 premature infants admitted to the neonatal intensive care unit (NICU) of a university hospital. Comparison between the groups did not yield a statistically significant difference relative to the crying time, salivary cortisol, or heart rate (HR). Human milk appears to be as effective as sucrose in relieving acute pain associated with ophthalmoscopy. The study’s limitations included its small sample size and lack of randomization. Experimental investigations with greater sample power should be performed to reinforce the evidence found in the present study.

Identification of novel elements of the Drosophila blisterome sheds light on potential pathological mechanisms of several human diseases.

Main developmental programs are highly conserved among species of the animal kingdom. Improper execution of these programs often leads to progression of various diseases and disorders. Here we focused on Drosophila wing tissue morphogenesis, a fairly complex developmental program, one of the steps of which - apposition of the dorsal and ventral wing sheets during metamorphosis - is mediated by integrins. Disruption of this apposition leads to wing blistering which serves as an easily screenable phenotype for components regulating this process. By means of RNAi-silencing technique and the blister phenotype as readout, we identify numerous novel proteins potentially involved in wing sheet adhesion. Remarkably, our results reveal not only participants of the integrin-mediated machinery, but also components of other cellular processes, e.g. cell cycle, RNA splicing, and vesicular trafficking. With the use of bioinformatics tools, these data are assembled into a large blisterome network. Analysis of human orthologues of the Drosophila blisterome components shows that many disease-related genes may contribute to cell adhesion implementation, providing hints on possible mechanisms of these human pathologies.

A manipulacao de prematuros em uma Unidade de Terapia Intensiva Neonatal

Os prematuros são submetidos a diversas manipulações e procedimentos durante internação em unidades neonatais, com consequências deletérias para a saúde. O objetivo do presente estudo foi descrever a manipulação a que são submetidos os prematuros durante as 24 horas em uma unidade de terapia intensiva neonatal (UTIN). Estudo observacional, descritivo, exploratório, realizado com 20 prematuros, filmados continuamente por um período de 24 horas, de setembro de 2008 a março de 2009 numa UTIN. Os prematuros foram submetidos a uma média de 768 manipulações e 1.341 procedimentos. A manipulação durou em média 2 horas e 26 minutos em um período de 24 horas. Cada manipulação agrupou uma média de 2,2 procedimentos, a maioria no turno matutino As manipulações isoladas representaram 65,6% do total de manipulações e a maioria teve duração inferior a um minuto. Conclui-se que nas 24 horas avaliadas, os prematuros foram submetidos a um excesso de manipulações na UTIN.

Polymorphisms of the " macrophage migration inhibitory factor " gene in infectious diseases

Summary The proinflammatory cytokine macrophage migration inhibitory factor (MIF) has emerged as a central mediator of inflammation and innate immune defense against infections. MIF has been shown to play an important role in the pathogenesis of infectious diseases like sepsis, tuberculosis and autoimmune inflammatory diseases, such as arthritis, inflammatory bowel disease and asthma. Two functional polymorphisms of the MIF gene promoter, a five to eight CATT repeat microsatellite at position -794 and a G/C SNP at position -173, have been associated with increased susceptibility to or severity of autoimmune inflammatory diseases like arthritis, colitis and atopy. The aim of this thesis was to define whether, and if so by which mechanisms, MIF gene polymorphisms influence the susceptibility to or the outcome of one of the most severe and one of the most prevalent infectious diseases: meningococcal sepsis and tuberculosis, respectively. The results of the comparison between 1106 patients suffering from severe meningococcal infections and 434 healthy volunteers showed that carriers of the CATT5-5 genotype were protected from meningococcemia. A transmission disequilibrium test involving 106 families confirmed this association. At baseline and after stimulation with Neisseria meningitidis, the CATT5 MIF promoter drove lower transcriptional activity than the CATT6 or CATT7 alleles in human monocytic cells and whole blood of CATT5-5 healthy individuals tended to produce less MIF than whole blood of CATT6-6 individuals. Beyond, we describe several new MIF gene polymorphisms in Africans. Genotyping the CATT microsatellite and the -173*G/C SNP revealed great genetic diversity in six African ethnic groups. Comparing 471 African tuberculosis cases and 932 matched healthy controls, we observed ethnicity dependent associations of the -173*G/C and the CATT5-8 with susceptibility to or severity of tuberculosis, but confirmation in larger cohorts ìs needed. In conclusion, we report that homozygous carriage of a low expression allele of the MIF gene protects from meningococcal disease. These results support the concept that analyses of MIF genotypes in patients with sepsis may help to classify patients into risk categories and to identify those patients who may benefit from anti-MIF therapeutic strategies.

Intimate Partner Violence Against Pregnant Women: Study About The Repercussions On The Obstetric And Neonatal Results

This observational, descriptive and analytic study aimed to identify the prevalence of IPV cases among pregnant women and classify them according to the type and frequency; identify the obstetric and neonatal results and their associations with the intimate partner violence (IPV) occurrence in the current pregnancy. It was developed with 232 pregnant women who had prenatal care at a public maternity hospital. Data were collected via structured interview and in the patients’ charts and analyzed through the statistic software SAS® 9.0. Among the participants, 15.5% suffered IPV during pregnancy, among that 14.7% suffered psychological violence, 5.2% physical violence and 0.4% sexual violence. Women who did not desire the pregnancy had more chances of suffering IPV (p<0.00; OR=4.32 and 95% CI [1.77 – 10.54]). With regards to the obstetric and neonatal repercussions, there was no statistical association between the variables investigated. Thus, for the study participants there were no negative obstetric and neonatal repercussions related to IPV during pregnancy.
