ABSTRACT

INTRODUCTION: Great part of Chagas disease (ChD) mortality occurs due to ventricular arrhythmias, and autonomic function (AF) may predict unfavorable outcomes. We aimed to evaluate the predictive value of AF indexes in ChD patients. METHODS: The Bambuí Study of Aging is a prospective cohort of residents ≥60 years at study onset (1997), in the southeastern Brazilian city of Bambuí (15,000 inhabitants). Consented participants underwent annual follow-up visits, and death certificates were tracked. AF was assessed by the maximum expiration on minimum inspiration (E:I) ratio during ECG acquisition and by heart rate variability indices: SDRR (standard deviation of adjacent RR intervals) and RMSSD (square root of the mean of the sum of squares of the differences between adjacent RR intervals)), calculated using a computer algorithm. Cox proportional hazards regression was performed to access the prognostic value of AF indexes, expressed as terciles, for all-cause mortality, after adjustment for demographic, clinical and ECG variables. RESULTS: From 1742 qualifying residents, 1000 had valid AF tests, being 321 with ChD. Among these, median age was 68 (64-74) years, and 32.5% were men. In Cox survival analyses, only SDRR was associated with all-cause mortality in non-adjusted models: SDRR (hazard ratio (HR): 1.26 (95% CI 1.08-1.47), p < 0.001), E:I ratio (HR: 1.13 (95% CI 0,98-1.31), p = 0.10) and RMSSD (HR: 0.99 (0.86-1.16), p = 0.95). After adjustment for sex and age, none of the indexes remained as independent predictors. CONCLUSION: Among elderly patients with ChD, AF indexes available in this cohort were not independent predictors of 14-year mortality.

ABSTRACT

BACKGROUND: The development of a psychometric measure for assessing democratic culture in organizations is described. METHODS: Two studies were conducted. A literature review of studies reporting democratic culture instruments was undertaken. Six databases were used within the timeframe of between 2015 and 2020. Four specialists rated the derived items on clarity, relevance, and translation via the content validity coefficient (CVC). An exploratory factor analysis (EFA) was performed with 225 individuals and the internal consistency was evaluated by Cronbach's alpha. RESULTS: A set of 2,049 articles were obtained in the literature review. The content validity coefficient allowed us to gather 96 items. The EFA achieved a final multidimensional solution formed of 58 items in 6 correlated factors: Citizen Participation, Tolerance and Openness, Organizational Citizenship, Traditionalist Dogmatism, Individualism and Rebellion, and Punitive Authoritarianism. Cronbach's alpha ranged from .59 to .78. CONCLUSION: This article presented several procedures used to develop a new measure of democratic culture in organizations.

ABSTRACT

We sought to investigate the prognostic value of the electrocardiogram (ECG) electrical axes (P wave, T wave and QRS) as predictors of mortality in the 14-year follow-up of the prospective cohort of all residents ≥60 years living in the southeastern Brazilian city of Bambuí, a population with high prevalence of Chagas disease (ChD). Baseline ECG axes were automatically measured with normal values defined as follows: P-wave axis 0° to 75°, QRS axis -30° to 90°, and T axis 15° to 75°. Participants underwent annual follow-up visits and death was verified using death certificates. Cox proportional hazards regression was used to assess the prognostic value of ECG axes for all-cause mortality, after adjustment for potential confounders. From 1,742 qualifying residents, 1,462 were enrolled, of whom 557 (38.1%) had ChD. Mortality rate was 51.9%. In multivariable adjusted models, abnormal P-wave axis was associated with a 48% (hazard ratio [HR] = 1.48 [95% confidence interval (CI) 1.16-1.88]) increased mortality risk in patients with ChD and 43% (HR = 1.43 [CI 1.13-1.81]) in patients without ChD. Abnormal QRS axis was associated with a 34% (HR = 1.34 [CI 1.04-1.73]) increased mortality risk in patients with ChD, but not in individuals without ChD. Similarly, in the ChD group, abnormal T-wave axis was associated with a 35% (HR = 1.35 [CI 1.07-1.71]) increased mortality, but not in patients without ChD. In conclusion, abnormal P-wave, QRS, and T-wave axes were associated with increased all-cause mortality in patients with ChD. Abnormal P-wave axis was associated with mortality also among those without ChD, being the strongest predictor among ECG variables.

ABSTRACT

Over 100 years have elapsed since the discovery of Chagas disease and there is still much to learn regarding pathogenesis and treatment. Although there are antiparasitic drugs available, such as benznidazole and nifurtimox, they are not totally reliable and often toxic. A recently released negative clinical trial with benznidazole in patients with chronic Chagas cardiomyopathy further reinforces the concerns regarding its effectiveness. New drugs and new delivery systems, including those based on nanotechnology, are being sought. Although vaccine development is still in its infancy, the reality of a therapeutic vaccine remains a challenge. New ECG methods may help to recognize patients prone to developing malignant ventricular arrhythmias. The management of heart failure, stroke and arrhythmias also remains a challenge. Although animal experiments have suggested that stem cell based therapy may be therapeutic in the management of heart failure in Chagas cardiomyopathy, clinical trials have not been promising.

ABSTRACT

La definición moderna de Salud Global ha ampliado su alcance más allá de las enfermedades desatendidas y los países de bajos ingresos y subdesarrollados. Las iniciativas actuales apuntan a mejorar la salud, reducir las disparidades y proteger contra las amenazas globales, en la búsqueda de una interacción entre las prácticas en salud, políticas y sistemas sanitarios. Considerando la transición epidemiológica actualmente en curso en los países de renta baja y media, y la creciente importancia epidemiológica de las enfermedades cardiovasculares y otras no transmisibles en detrimento de las enfermedades infecciosas y las deficiencias nutricionales, ha habido un interés creciente en la investigación sobre la Salud Global. Diversos aspectos -antes descuidados- de estas enfermedades, tales como la epidemiología, la prevención, el diagnóstico y el tratamiento, han sido abordados en las publicaciones actuales sobre Salud Global, lo que ha conducido a una mejor comprensión de la importancia de la salud como un bien público, allende fronteras. La evidencia científica avala las iniciativas más amplias en las que los gobiernos, las fundaciones y la sociedad civil deben compartir las responsabilidades y los fondos para alcanzar equidad sanitaria, la principal meta de la Salud Global.

ABSTRACT

The modern definition of Global Health has expanded its scope beyond neglected diseases and low-income and underdeveloped countries. The current initiatives focus on improvement of health, reduction of disparities and protection against global threats, seeking for interaction with health practices, policies and systems. There has been a growing interest on Global Health research, given the epidemiological transition currently underway in low and mid-income countries and the increasing epidemiological importance of cardiovascular and other non-communicable diseases, to the detriment of infectious diseases and nutritional deficiencies. Various aspects-formerly neglected-of these diseases, such as epidemiology, prevention, diagnosis and therapy, have been addressed in Global Health publications, leading to a better understanding of the importance of health as a public good, beyond borders. Scientific evidence supports broader initiatives in which governments, foundations and the civil society must share responsibilities and funding to achieve health equity, the main goal of Global Health.

ABSTRACT

A tuberculose (TB) é dos mais graves problemas de saúde humano e associa-se a pobreza, incipiência do sistema de saúde, deficiência de gestão que dificulta a diminuição de doenças de determinismo social, epidemia do vírus da imunodeficiência humana e imunodeficiência adquirida e multirresistência do M. tuberculosis. O acometimento extrapulmonar ocorre em 15% dos casos de TB e pode evoluir com amesma sintomatologia geral do acometimento pulmonar, com variações na dependência de sua localização e gravidade. Este relato apresenta paciente com hematúria e polaciúria incapacitante para a vida social, associada inicialmente à neoplasia, e determinada pela TB geniturinária, com diagnóstico após histopatologia de espécime clínico obtido da bexiga, em que o tempo longo para o diagnóstico foi determinante para grave sequela. Objetiva alertar para a TB como doença permanente no Brasil ea necessidade de ser considerada sempre como diagnóstico diferencial de doenças pulmonares ou extrapulmonares.


Tuberculosis (TB) is among the most serious human health concerns and is associated with poverty, limited availability of health care services and bad management, all of which negatively affect the possibility of reducing socially-determined diseases, such as HIV/AIDS epidemics and multidrug resistant M. tuberculosis. Extrapulmonary involvement occurs in 15% of TB cases and can develop with the same overall symptomatology of exclusively pulmonary involvement, with smaller variations depending on location and severity. This report presents a patient with hematuria and pollakiuria with incapacitating effects on social life, initially thought of as a malignancy and later identified as genitourinary TB. Diagnosis was based on histopathology of clinical specimens from the bladder. Time elapsed between onset and diagnosis led to considerable sequelae. This report aims at raising awareness of TB as a permanent concern in Brazil and of the need to always considered it as a differential diagnosis of pulmonary or extrapulmonary disease.

ABSTRACT

Objetivou-se avaliar as características clínicas, formas de tratamento e evolução dos pacientesportadores de disrafismo espinhal, atendidos no Hospital de Clínicas da Universidade Federal de Uberlândia (HC-UFU) em um intervalo de onze anos (janeiro de 1992 a dezembro de 2002). Realizou-se um estudo descritivo, identificando os casos analisados conforme sua apresentação clinica (espinha bífida oculta, meningocele e mielomeningocele). As seguintes variáveis foram analisadas: gênero, raça, idade materna, peso de nascimento, época do diagnostico, presença de malformações associadas, tratamento cirúrgico, ocorrência e causa do óbito. Dentre os pacientes analisados, 50,9% eram do sexo feminino e 73,1% da etnia branca. Em relação a idade materna, a maioria (68,5%) encontrava-se entre 20 e 29anos. A media dos pesos dos pacientes ao nascimento foi de 2.938 gramas. Em 81,5% dos casos, o diagnostico dodisrafismo foi feito ao nascimento. Considerando a apresentação clinica, observou-se a ocorrência de mielomeningocele em 94,4% dos casos, de espinha bífida oculta em 3,8% e de meningocele em 2,8%. A localização do disrafismo preponderante foi a lombossacral, correspondendo a 84% dos casos. Dentre as lesões associadas, observou-se maior freqüência de hidrocefalia, Síndrome de Arnold Chiari tipo II e estrabismo. A cirurgia foi realizada em 94,4% dos pacientes. Houve óbito em 9,26% dos casos. O índice de diagnostico intra-utero dos disrafismos espinhais foi baixo,refletindo, possivelmente, a deficiente disponibilidade de equipamentos apropriados e/ou inexperiência dos profissionais nos serviços públicos. Os demais achados foram semelhantes aos da literatura.


The objective was to evaluate the clinical aspects, treatment and evolution of the carriers of spinedysraphism. The charts of the carriers of spine dysraphism (occult spina bifida, meningocele and myelomeningocele),admitted in the hospital at the period were analysed and the following were studied: gender, race, age of the mother,weight at birth, age of diagnosis, associated malformations, surgical treatment, death. 50,9% of the patients were female and 73,1% white; 68,5% of the mother were between 20 and 29 years old. The average weight of the neonates were 2938 g. At 81,5% the diagnosis of dysraphism were made at birth. Myelomeningolcle were present in 94,4% of the patients, occult spina bifida in 3,8% and meningocele in 2,8%. At lombosacral area were found 84% of the malfomation. Amongthe associated lesions were found the Hydrocefalia-, Arnold Chiari II and strabism. Surgical treatment were realized in 94,4% of the children and occurred 9,26% of death. The rate of intra-uterine diagnosis were very low expressing, probably, the deficiency of equipment and specialized assistance at the public health system.

ABSTRACT

Objetivos: descrever o perfil sócio-econômico-cultural das gestantes que utilizam o ambulatório de pré-natal e identificar os temas de educação referentes ao período puerperal e gestacional eleitos pelas gestantes. Método: estudo transversal, exploratório e descritivo. Foram realizadas 90 entrevistas semi-estruturadas com gestantes acompanhadas no ambulatório de pré-natal de um Centro Municipal de Saúde localizado na cidade do Rio de Janeiro. O estudo foi aprovado pelo Comitê de Ética em Pesquisa da Secretaria Municipal de Saúde ­ RJ, número de registro 231/08. Resultados: a faixa etária predominante (48%) foi a de gestantes de 18 a 25 anos. A maioria (62%) não completou o 2° grau e trabalha no setor de serviços. A renda familiar de 94% das entrevistadas é inferior a três salários mínimos. Grande parte (76%) delas não planejou a atual gravidez e 33% têm histórico de abortos anteriores. Algumas admitiram ingerir bebidas alcoólicas (13,3%) e 7,7% delas são tabagistas. Os "sinais e sintomas do trabalho de parto" foi o tema educativo eleito pela maioria. Conclusão: conhecer o perfil das gestantes permitiu que fossem identificadas as vulnerabilidades que fragilizam sua saúde. A pesquisa desenvolvida é relevante e pode fundamentar o planejamento da assistência prestada. A educação em saúde é uma ferramenta capaz de colaborar com um bom prognóstico da gravidez e diminuir os índices de mortalidade materna e neonatal.(AU)


Objective: to describe the socio-economic-cultural pregnant women who use outpatient prenatal care and identify the themes of education for the pregnancy and puerperal period elected by women. Method: it's a cross-sectional, exploratory and descriptive study. In a prenatal care from healthcare center located in Rio de Janeiro were carried out 90 semi-structured interviews with pregnant women. This study was approved by Research Ethics Committee in Health Municipal Secretariat-RJ, number of register 231/08. Results: the predominant age group (48%) was that of pregnant women 18 to 25 years, most (62%) did not complete high school and are employed in the service sector. The absolute majority (94%) have family income less than three minimum wages. The most women (76%) did not plan the current pregnancy and 33% had previous abortion. Some women were drinking alcohol (13.3%) and smoking (7.7%). Signs and symptoms of labor was the theme of education elected by the majority (56%). Conclusion: to understand the socioeconomic and cultural allowed be identified vulnerabilities to the health of women. This research has great relevance to support the planning of health care. Through health education we can contribute to a good outcome of pregnancy and future pregnancies and to reduce the rates of maternal and neonatal mortality.(AU)

ABSTRACT

A hemorragia pós-parto representa emergência obstétrica que surge em 4 a 6% dos partos, constituindo-se uma das principais causas de morte materna. No pós-parto imediato, as etiologias mais frequentes são: a atonia uterina, a presença de lacerações do canal de parto, a retenção de restos placentários e os distúrbios de coagulação. Este artigo apresenta o relato de uma paciente com hemorragia uterina no pós-parto imediato, submetida a histerectomia subtotal devido à atonia uterina refratária ao tratamento clínico.


Postpartum hemorrhage (PPH) is an obstetric emergency that arises in 4 to 6% of births. It is a major cause of maternal morbidity. In the immediate postpartum period, the most common etiologies are: uterine atony; trauma-related bleeding due to lacerations of the birth canal, incisions or uterine rupture; retention of placenta remains; and coagulation disorders. This article is the case report of a patient with uterine bleeding in the immediate postpartum period, who underwent subtotal hysterectomy due to uterine atony not controlled with medical treatment.

ABSTRACT

A hemorragia pós-parto (HPP) constitui a complicação obstétrica com maior índice de mortalidade materna em todo o mundo. Até 90% desses óbitos podem ser evitados com cuidado médico adequado. Este trabalho objetiva a atualização da classificação e diagnóstico da HPP com o intuito de tornar o conhecimento adequado quanto às medidas preventivas e a instituição da terapêutica em tempo hábil e de forma eficaz.


The postpartum hemorrhage (PPH) is the obstetric complication with the largest maternal mortality rate all over the world. Motivated by the estimate that up to 90% of those deaths could be avoided by appropriate medical care, this work aims at supplying the professionals in charge of the attendance of the delivering women general knowledge on how to proceed before HPP situation, reducing the maternal morbimortality. It is a bibliographical revision accomplished by scientific articles obtained through searches in portals recognized in the academic-scientific group that approaches some of the definitions of PPH accepted currently, its classification and diagnosis. The knowledge of the risk factors makes possible to the assistance team to take preventive measures and to be prepared to institute the therapeutic measures, in case it is necessary, in skilled time and in an effective way. It is hoped that the correct intervention in the cases leads to a reduction of the maternal morbimortality due to that condition, something not just desirable, but feasible.

ABSTRACT

OBJECTIVE: Evaluate correlations between variations in eletrocardiogram (ECG) recordings and acute myocardial infarction. METHODS: Use of a low-cost software to digitalize printed and/or ".pdf" file format ECG recordings. Calculation of ST-segment area and amplitudes of the J and Y points. RESULTS: The amplitude of the Y point holds maximum correlation with troponin concentration. ST-segment elevation is not a good statistical indicator of myocardial infarction severity. There is a strong negative correlation between the amplitude of the J point and the amount of magnesium ions, but no statistical correlation with sodium or calcium ions. Neither method for calculating the ST-segment area (pixel counts and interpolation) indicated any significant differences in the results. CONCLUSION: The software used proved to be functional and cost-effective. Y point amplitude is a sensitive marker of myocardial infarction, and is also a calculation method both simpler to use and less subject to error than the calculation of the ST-segment elevation area.

ABSTRACT

OBJETIVO: Avaliar correlações entre as variações do eletrocar¡diograma (ECG) e o infarto agudo do miocárdio. MÉTODOS: Uso de software de baixo custo para digitalização de ECG impressos e/ou em formato "pdf". Cálculo de área do segmento ST e das amplitudes dos pontos J e Y RESULTADOS: A amplitude do ponto Y possui máxima correlação com a concentração da enzima troponina. O supradesnivelamento do segmento ST não se constitui bom indicador estatístico da gravidade do infarto. Existe uma forte correlação negativa entre a amplitude do ponto J e a quantidade de íons magnésio, mas nenhuma correlação estatística com os íons sódio ou cálcio. Os dois métodos de cálculo da área do segmento ST (contagem de pixels e interpolação) não mostraram diferenças significativas nos resultados. CONCLUSÃO: O software utilizado mostrou-se viável do ponto de vista econômico e funcional. A amplitude do ponto Y é um marcador sensível à ocorrência do infarto, tendo cálculo mais simples e menos sujeito a erros do que o cálculo da área de supradesnivelamento do segmento ST.
