Efeitos do treino resistido na capacidade funcional e na reatividade pressórica em pacientes intradialíticos

Pacientes com doença renal crônica (DRC) submetidos ao treinamento resistido durante a hemodiálise apresentam benefícios substanciais dos sistemas muscular e cardiovascular, da capacidade funcional e da sua qualidade de vida. Entretanto, as melhorias na reatividade pressórica ainda não estão bem esclarecidas. O objetivo foi analisar o efeito do treino resistido na melhora da capacidade funcional e da reatividade pressórica em pacientes hemodialisados, em Natal/RN no ano de 2014. Trata-se de um ensaio clínico controlado e randomizado, com amostra de 64 pacientes, com média de idade de 42,28 (±11,48) anos, distribuídos em grupo experimental (GE) e controle (GC). Para mensurar os ganhos de força de membros inferiores foram utilizados os testes de sentar e levantar e de levantar e caminhar, já para a reatividade pressórica o teste cold pressor, em ambos os grupos antes e após a intervenção. Além disso, apenas o GE participou do treinamento resistido durante a hemodiálise em 16 semanas, composto por 3 sessões semanais, 3 séries de 10 repetições máximas (RM) estimadas (para extensores de joelho e flexores de quadril e joelho), entre 50 a 70% de 10 RM. Para a intensidade do treinamento foi utilizada a escala de Borg entre 11 a 14 durante as seções. Os dados foram analisados utilizando o Teste t para amostras independentes (inter-grupos) bem como para comparar a diferença das médias nos grupos pré e pós-intervenção (intra-grupos) a partir do Teste t para amostras repetidas. Para todas as variáveis foi considerada a significância estatística de 5% executados no software SPSS® 20.0. O estudo foi aprovado pelo comitê de ética do Hospital Universitário Onofre Lopes (HUOL - UFRN) número 37992214.2.0000.5292. Após a intervenção, verificou-se que os pacientes do GE tiveram um desempenho melhor nos testes de força (p<0,001) em comparação ao GC. Resultado também observado na pressão arterial sistólica e diastólica (PAS e PAD) ambas de repouso que apresentaram redução dos níveis pressóricos apenas no GE (p<0,001). Na reatividade pressórica tanto nos períodos pré bem como após 2 minutos também demonstraram reduções estatisticamente significativas do GE (p<0,001 e p=0,012) respectivamente quando comparado ao GC. Conclui-se que o treinamento resistido melhorou desempenho nos testes de força de membros inferiores beneficiando a capacidade funcional dos pacientes em hemodiálise, como também a pressão arterial de repouso e os níveis de reatividade pressórica obtiveram reduções significativas de seus valores após a intervenção. Além disso, este tipo de treinamento também pode ser utilizado como uma estratégia de proteção aos fatores de risco cardiovascular em pacientes renais crônicos.

Validação do instrumento dos indicadores observáveis da qualidade do cuidado em instituições de longa permanência para idosos

The Nursing Homes are an important alternative care in the world, but Brazil still has no valid instrument to monitor the quality these institutions. In the United States, the Observable Indicators of Nursing Home Care Quality Instrument (OIQ) is used to assess the quality of Nursing Home care using 30 indicators of structure (2 dimensions) and process (5 dimensions) related to quality person-centered care. The present study aimed at cross-culturally adapting the OIQ in order to evaluate the quality of Nursing Home care in Brazil. Conceptual and item equivalence were determined to assess the relevance and viability of OIQ in the Brazilian context, using the Content Validity Index (CVI) and a group of specialists composed of 10 participants directly involved in the object of study. Next, operational, idiomatic and semantic equivalence were carried out concurrently. This consisted of 5 phases: (1) two translations and (2) their respective back translations; (3) formal appraisal of referential and general meaning; (4) review by a second group of specialists; (5) application of the pretest at three Nursing Homes by different social entities: health professionals, sanitary surveillance regulators and potential consumers. Measurement equivalence was evaluated by the Cronbach’s alpha test to verify the internal consistency of the instrument. To measure inter-evaluator agreement, the General Agreement Index (ICG) and Kappa coefficient were used. Timely compliance and 95% Confidence Interval of indicators, dimensions and total construct were estimated. The CVI obtained high results for both relevance (95.3%) and viability (94.3%) in the Brazilian context. With respect to referential meaning, similarity was observed, ranging between 90-100% for the first back translation and 70-100% for the second. In relation to general meaning, version 1 was better, classified as “unchanged” in 80% of the items, whereas in version 2 it was only 47%. In the pretest, the OIQ was easy to understand and apply. The following outcomes were obtained: a high Cronbach’s alpha (0.93), satisfactory ICG (75%) and substantial agreement between the pairs of evaluators (health professionals, regulators from the Superintendency of Sanitary Surveillance –SUVISA-, and potential consumers), according to the Kappa coefficient (0.65). It´s possible take the operational equivalence held since it preserved the original layout in the Brazilian version from the maintenance in application mode, response options, number of items, statements and scores. The performance of nursing homes obtained approximate average scores of 87, a variation 55-111 considering a range from 30 to 150 points. The worst outcomes were related to process indicators with a mean of 2.8 per item, while structure was 3.75 on a scale of 1 to 5. The lowest score was obtained for the care dimension (mean 2). The OIQ version was deemed to be a valid and reliable instrument in the Brazilian context. It is recommended that health professionals, regulators and potential consumers adopt it to access and monitor the quality of Nursing Home care and demonstrating opportunities for improvement.

Prevalência e fatores associados à alteração vocal em idosos institucionalizados com capacidade cognitiva preservada

Voice disorders (VD) in the elderly can interfere negatively in communication, emotional well-being and quality of life, conditions that correspond to greater exposure to illness and social isolation bringing consequent economic impact for the health system. It is assumed that institutionalized confinement, weakness and morbidity associated to nursing home (NH) contribute to transform VD an especially prevalent condition in institutionalized elderly, including those without cognitive impairment. Thus, the aim of this study was to determine the prevalence and associated factors of VD in NH elderly residents without cognitive impairment. There is no epidemiological diagnostic instruments of VD for elderly populations, so the first step of this study was dedicated to prepare and analyze the psychometric properties of a short, inexpensive and easy to use questionnaire named Screening for Voice Disorders in Older Adults (Rastreamento de Alterações Vocais em Idosos—RAVI). The methodological procedures of this step followed the guidelines of the Standards for Educational and Psychological Testing and contemplated validity evidence based on test content, based on response processes, based on internal structure and based on relations with other variables, as well as reliability analysis and clinical consistency. The result of the validation process showed that the RAVI final score generate valid and reliable interpretations for the epidemiological diagnosis of VD in the elderly, which endorsed the use of the questionnaire in the second stage of the study, performed in ten NH located in the city of Natal, Rio Grande do Norte. At this stage, data from socioeconomic and demographic variables, lifestyle, general health conditions and characterization of the institution were collected. It was performed a bivariate analysis and it was calculated the prevalence ratio as a magnitude association measure, with a confidence interval of 95%. The variables with p-value less than 0.20 were included in the multiple logistic regression model that followed the Forward selection method. The odds ratio found in the multivariate model was converted into prevalence ratio and the level of significance was 5%. The sample consisted of 117 subjects with predominance of females and average of 79.68 (± 7.92) years old. The prevalence of VD was 39.3% (95% CI: 30.4-48.1%). The multivariate model showed statistically significant association between VD and depressive symptoms, smoking for a year or more and selfreported hearing loss. In conclusion, VD is a prevalent health condition in NH elderly residents without cognitive impairment and is associated with factors involving psychosocial, lifestyle and communicative disability that require attention of managers and professionals involved with NH environment. Strategies to encourage communication and social integration, actions to combat smoking and minimizing the effects of hearing loss could stimulate the physical well-being, emotional and mental health of institutionalized elderly population, contributing to the vocal and communicative maintenance, a more effective social inclusion and better overall health condition.

Aplicação de agentes remineralizantes sobre o esmalte clareado: eficácia contra o manchamento por café

The aim of this study was to evaluate the influence of remineralizing agents on the susceptibility of enamel cleared by the coffee pigmentation during office bleaching. Fifty bovine incisors were selected and randomly assigned into 5 groups (n = 10) on the basis of remineralizing agents: G1 gel hydrogen peroxide to 35% (control group); G2, hydrogen peroxide gel and a 35% gel 2% neutral fluorine; G3, hydrogen peroxide gel and a 35% nanostructured calcium phosphate gel, G4, hydrogen peroxide gel and a 35% casein fosfoptídia-phosphate and amorphous calcium folder; G5 hydrogen peroxide gel to 35% without mineralizing agent. All groups exception G1 (control group) were subjected to pigmentation soluble coffee according to the manufacturer's guidelines. The samples were immersed in coffee at temperature of 55° C, 1 time a day for 4 minutes. Color changes were performed by Easyshade spectrophotometer at CIE Lab method before and after 3 whitening sessions. Data were analyzed by analysis of variance ANOVA. The results showed statistically significant differences between the remineralizing substances for the parameters L *, a *, b * ΔE (p <0.0001). The L * values for the group G5, and the b * for G2 and G5 groups differed from the control group. After the 3rd whitening session, Fluor's group (G2) and that without mineralizing agent (G5) showed ΔE values less than the control group that did not undergo pigmentation. It was concluded that only the nanoclusters remineralizing agents Phosphopeptides Casein-Amorphous Calcium Phosphate and Calcium Amorphous phosphate were able to reduce the coffee interference whitening efficacy of hydrogen peroxide.

Gasto com a internação de idosos em unidades de terapia intensiva

Introduction: Population aging in Brazil underscores the need to discuss the proper management of the budget allocated in health field, especially in the sectors of high complexity, where coexist costly procedures, limited resources and the need for cost containment. In the other hand, demand is growing in a way directly proportional to the increase in the number of elderly in country. Objective: In this way, this research had as main objective to analyze the costs resulting from the admission of elderly in intensive care units (ICU) and its associated factors. Methods: This is a cross-sectional study with a quantitative approach and featured as a descriptive and exploratory research. Data were collected from medical records of elderly hospitalized in ICU from a brazilian city called Natal-RN, between november first, 2013 and january, 31 of 2014. The variables collected relate to the socio demographic profile, morbidity framework and characterization of hospitalization. The dependent variable was categorized by quartile 75 in high and low expense of hospitalization and submitted to chi-square test with the independent variables of the survey. Associations with p value <0.20 in the bivariate analysis were submitted to the technique of multiple logistic regression. We opted for the construction of three regression models from the above algorithm: general regression model, composed by all 493 hospitalizations in the study, other made with 181 individuals admitted in health public system (SUS) and a third one related to 312 cases from private service in health area. Results: In the general regression model, the variables respiratory diseases, hospitalizations in the private system, disoriented patient and previous stroke were associated with greater probability of high spending in the ICU. In the other hand, in SUS kind of hospitalizations, this probability was associated with disoriented patient, 80 years old or more, sepsis and admission for clinical reason. In the cases from the private network health, the high expenditure was associated with respiratory disease, mechanical ventilation, hospitalization for clinical reason and disoriented patients. Conclusion: The increased expenditure on hospitalization of elderly in intensive care depends on the clinical conditions of individuals. This highlights the importance of avoiding hospitalizations due to diseases sensitive to primary care by health preventive actions and providing comprehensive care to the elderly. In addition, obtaining different explanatory models, according to kind hospital funding, demonstrates the importance of the organization in health services related to composition of costs of hospitalization among the elderly. Another question founded was the need that to improve the funding, we must use rationally the available resources by avoiding unnecessary hospitalizations of elderly people in the extremes of severity. On this kind of precarious funding, ICU hospitalization of elderly non-critical or in a terminal state can compromise the quality of services provided to those who really need intensive care.

Análise da atuação do Ministério Público Estadual na assistência materno infantil do Rio Grande do Norte

Maternal and infant mortality have become a serious public health problem in Brazil, especially in northeasternand northern regions.In RioGrande do Norte, the high rates ofdeathsofmothersandbabies haveconcerned not onlythehealthauthorities andjusticeagenciessuch as the prosecution service. In 2011, State Public Ministry (MPE) has developed a proposition which was called “Nascer com Dignidade”, focused on the monitoring ofcare givenin prenatal, childbirth andpost childbirthin the cities. The aim of thisstudy was toinvestigate how the intervention of MPE works in maternal and child care. The method adopted to survey data was the case study by analyzing the skills of the reports which were carried out in four of the eight Public Health Regional Units (URSAP).A total of 26municipalities were chosenand the results showfragilityparticularly inprenatal care which can result in complicationsin childbirthand postpartumlike:incomplete health family teams(in05cities), lack of access orinaccessibility to laboratory tests(16 cities) and lack of the pregnant woman'sattachment to thebirthing place(in26 cities). Based on this reality, MPE has adopted relevant attitudes as filing public civil suits, compliance of Conduct Adjustment Declaration in the municipal management and performing interventions in heath care centers and maternity clinics of the state. Thereforeit is known thatPublic Ministryis of paramount importanceto indicatethe necessaryadjustmentsto addressinfant and maternalmortalityin the state (mean of 65/100,000 and16/100,000respectively) and give the city hall the responsibility for the health care quality provided to their citizens. These factors demand theprinciples ofuniversality and integrality to be performed in order to reduce social inequities.

O envelhecimento no espaço midiático: a produção de sentidos pelos meios jornalísticos

Aging as a social phenomenon is guided in the ways of production and reproduction, that is linked to the peculiarities and compliances of the social structure influence the values and erected senses. The search for the understanding of the reality will be given by the appropriation of knowledge/information that in contemporary times are increasingly tied to the media means, so that they go beyond the mere condition media, reaching the condition of instruments of direct, attitudes and opinions production. Among the media instruments, there are news medias, that are important means of information dissemination and consequently production of senses, including over aging. Thus, the objective is to: apprehend the social representations and meanings associated with aging in the media space about aging; browse the social representations about aging in media space and their influence on the relations that are established in the cultural socio-economic context. To do it The Theory of Social Representation will be used. To collect the data, 57 online news from the three main state newspapers were studied: Tribuna do Norte, Gazeta do Povo and Jornal de Hoje, which were captured through a search tol of these newspaper sites, using the words: “aging””elderly”. These materials were analyzed making use of Bardin’s Qualitative Analysis, which allowed the establishment of five categories, namely: Aging and violence; Aging in contemporary times; Aging and health; Aging and citizenship; and Aging, work and action. In the first category news reporting violent situations are framed the regardless of the victim’s condition or the one charged by the violence, the fragility of elderly persists. In Aging in contemporary times the attempts of the news media to explain the demographic changes of the quantitative increases in the elderly, the burden it may lead to the full development of the country are noticed. In Aging and health is noticed the imminent end of the condition brought on age, as a synonym for diseases and conditions. In the fourth category, Aging and citizenship situations are shown where peculiarities and needs or the elderly need to turn into obligation to be fulfilled, denouncing the condition of low expression and social power of the class. Finally, in Aging, work and action situations that indicate the non-expectation of elderly interaction with new technologies and participation in decision-making directions of society are brought. In a general and specific form this analysis allowed learning the ways of production of meanings about aging in the papers, as these ones tend to represent aging through intentioned situations as hegemonic needs, building the social representation of the elderly as fragile person, submissive, inactive, subject to violence and susceptible to becoming ill.

Prevalência e fatores associados ao Near Miss Materno: inquérito populacional em uma capital do Nordeste Brasileiro

The scope of this study was to determine the prevalence of near misses and complications during pregnancy and the puerperal period, identifying the main clinical and intervention markers and socioeconomic and demographic factors associated with near misses. It involved a cross-sectional, population-based and probabilistic study with multi-stage complex sampling design conducted in Natal, State of Rio Grande do Norte, Brazil. A validated questionnaire was given to 848 women aged 15 to 49 identified in 8,227 households in 60 census sectors. In theanalysis of associations, the Chi-square test applied and calculated the prevalence ratio (PR) with Confidence Interval (CI) of 95% and 5% significance. The prevalence of maternal near misses was 41.1/1000LB, with hospitalization in an Intensive Care Unit (19.1/1000LB) and eclampsia (13.5/1000LB) being the most important markers. The prevalence of complications during pregnancy and the puerperal period was 21.2%. The highest prevalence of near misses was observed in older women, of black/brown race and low socioeconomic status. Conducting population surveys is feasible and may add important information to the study of near misses and the markers highlight the need for enhancing maternal care to reduce health inequality.

Toothache and social and economic conditions among adolescents in Northeastern Brazil

O objetivo deste estudo foi relacionar dor de dente com condição socioeconômica, acesso aos serviços de saúde bucal e estilo de vida em adolescentes do município de Sobral, Ceará, desenvolvido com delineamento transversal analítico, com amostra composta por 688 indivíduos. A prevalência de dor de dente no grupo pesquisado foi de 31,8%. Para avaliar a relação entre as variáveis independentes e a dor de dente, realizou-se teste de associação pelo qui-quadrado, estimando-se a razão de prevalências por meio da regressão de Poisson. Os fatores que mais demonstraram relação com a dor de dente foram severidade da cárie, motivo do atendimento odontológico relacionado com urgência, frequência ao dentista e recebimento de escova na escola. Observou-se que a alta prevalência de dor de dente em adolescentes está diretamente relacionada às condições de acesso, assim como às características das ações desenvolvidas pelos serviços de saúde. Assim como há necessidade da implantação de serviços vinculados à promoção de saúde, pautados pela equidade e integralidade, é necessária a implantação de serviços de urgência que não simplesmente intervenham na dor de forma mutiladora, mas a encarem como mecanismo de estímulo ao desenvolvimento de procedimentos de prevenção das doenças bucais.

A desigualdade espacial do Baixo Peso ao Nascer no Brasil

Low birth weight (LBW) is a risk factor for neonatal and infant morbidity and mortality. In Brazil the highest percentages of low birth weight occur in regions of higher socio-economic status. The scope of this article is to ascertain the spatial distribution of low birth weight rates and the correlation with social and service indicators. The scale is ecological taking all the Brazilian states as units of analysis. The spatial analysis technique is the methodology used together with data from SINASC, IPEA and IBGE for 2009. Higher rates of low birth weight are found in the south/southeastern states (Global Moran: 0.267, p = 0.02). Clusters of the high-high type in the Southeast and of the low-low variety in states in the Amazon region are detected. The spatial inequality of low birth weight reflects the socio-economic conditions of the states. More developed regions have higher rates of low birth weight, therefore, the presence of the service and its use decrease infant mortality and increase LBW.

O processo ensino-aprendizagem e suas conseqüências na relação professor-aluno-paciente.

This study deals with the ethical and human aspects present in the teaching-learning process within the dentists' formation. It arises from the growing need for professionals involved with the quality of the services they provide for the population in health care centers. In this research a qualitative approach was used and data was obtained by means of focal groups, interviews and participative observation. The sample consisted of 28 dentistry students and 33 patients attended at the dentistry course. According to the results, it was shown that the main problems are the excess of authority in the teacher-student-patient relationship and the dissociation of the body-mind-spirit as seen in the biomedical model health practice. These findings show the future professionals' insufficient abilities for developing a satisfactory relationship with their patients and the need of considering these aspects during their formation.

Eficiência mastigatória e qualidade das próteses totais confeccionadas pelas técnicas tradicionais e simplificada: um ensaio clínico

Traditional methods for dentures fabrication require a wide clinical and laboratory procedures; however, there is no scientific evidence that these methods can produce better results when compared with simplified methods. Aim: To evaluate the effectiveness of a simplified methods for denture fabrication, comparing it to the traditional one through masticatory efficiency and prosthesis quality. Method: A randomized controlled trial was conducted with 50 patients, 25 rehabilitated with prosthesis produced by traditional technique and 25 rehabilitated by a simplified technique. The masticatory efficiency was evaluated by colorimetric method, using chewing capsules. The quality of prosthesis was obtained using a reliable and reproducible instrument. Statistical analysis of the masticatory efficiency and quality of the prosthesis was obtained by the Mann-Whitney test. Results: 39 patients completed the study, 18 on traditional group and 21 on simplified group. There was no difference between groups for the masticatory efficiency (p = 0.835) and the quality of the prosthesis (p = 0672). The evaluation of the overall quality of the prosthesis according to oral conditions, demonstrated significant difference on the height of the mandibular ridges (p = 0.010) and mandibular muscle attachments (p = 0.039). Conclusion: Complete dentures fabricated by simplified method were considered effective from the point of view of masticatory efficiency and quality of prosthetics, with results similar to those made by the traditional method.
