Content validation of an instrument to characterize people over 50 years of age living with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome

Objective: To present the development and validation of an instrument for characterizing people, aged 50 or over, who are carriers of the Human Immunodeficiency Virus / Acquired Immunodeficiency Syndrome. Methods: The content of the instrument, which was developed based on consulted literature and the professional experience of the researchers, was validated by seven experts. The validation was performed in two stages of evaluation, using the Kendall coefficient of concordance to evaluate, the first time, concordance among experts with regard to relevance, clarity, and completeness of content, and secondly, the adequacy and comprehensiveness. The Cochran test was used to evaluate the concordance regarding clarity, in the second evaluation. Results: There was disagreement among the experts in the first evaluation, and after reformulation of the instrument, concordance was obtained in the second evaluation. Conclusion: The instrument for characterizing this population was validated against the content being used by researchers, and is now made available for use.25141

Psychometric performance of the brazilian version of the Mini-cuestionario de calidad de vida en la hipertension arterial (MINICHAL)

This study aimed to evaluate the feasibility, acceptability, ceiling and floor effects, reliability, and convergent construct validity of the Brazilian version of the Mini Cuestionario de Calidad de Vida en la Hipertension Arterial (MINICHAL). The study included 200 hypertensive outpatients in a university hospital and a primary healthcare unit. The MINICHAL was applied in 3.0 (+/- 1.0) minutes with 100% of the items answered. A "ceiling effect" was observed in both dimensions and in the total score, as well as evidence of measurement stability (ICC=0.74). The convergent validity was confirmed by significant positive correlations between similar dimensions of the MINICHAL and the SF-36, and significant negative correlations with the Minnesota Living with Heart Failure Questionnaire - MLHFQ, however, correlations between dissimilar constructs were also observed. It was concluded that the Brazilian version of the MINICHAL presents evidence of reliability and validity when applied to hypertensive outpatients.194855864Fundo de Apoio ao Ensino, a Pesquisa e a Extensa (FAEPEX), Campinas, SP, Brazil [52899-10]Fundo de Apoio ao Ensino, a Pesquisa e a Extensa (FAEPEX), Campinas, SP, Brazil [52899-10

Síntomas de pacientes antes de la primera hospitalización por Síndrome Coronario Agudo

Este estudo objetivou caracterizar os pacientes quanto ao relato da presença de sintomas de dor torácica, dispneia e limitação das atividades diárias uma semana antes da primeira hospitalização por Síndrome Coronariana Aguda, segundo a forma de apresentação clínica, e compará-las. Estudo transversal, descritivo e correlacional. Utilizou-se um instrumento de avaliação clínica que investigou a presença e a gravidade dos sintomas de dispneia, precordialgia e restrição física decorrentes da isquemia do miocárdio. Com relação à limitação para realização de atividades físicas, pacientes com diagnóstico de angina instável mostraram maior comprometimento na semana que antecedeu a internação, assim como relataram a presença de dispneia e precordialgia com maior frequência do que os pacientes infartados em situações que vão desde realizarem grandes esforços como, por exemplo, caminhar na subida ou muito rápido no plano, até situações de repouso ou de pequenos esforços.The objective of this study was to characterize and compare patients regarding their report of experiencing chest pain, dyspnea and limitation of the daily life activities one week before their first hospitalization due to Acute Coronary Syndrome, according to the clinical presentation form, and compare them. This is a cross-sectional, descriptive and correlational study. A clinical evaluation instrument was used to investigate the presence and severity of dyspnea, chest pain and physical restriction due to myocardial ischemia. Regarding the limitation to carry out physical activities, patients diagnosed with unstable angina showed lower capacity the week before hospitalization, and reported experiencing dyspnea and chest pain more frequently than patients who had an infarction in situations ranging from making strong efforts, such as walking uphill or on a flat surface but very quickly, to resting and in situations of little effort.Estudio que objetivó caracterizar a pacientes en cuanto al relato de presencia de síntomas de dolor torácico, disnea y limitación de actividades diarias una semana antes de la primera hospitalización por Síndrome Coronario Agudo, según la forma de presentación clínica, y compararlas. Estudio transversal, descriptivo y correlacional. Se utilizó un instrumento de evaluación clínica que investigó la presencia y gravedad de síntomas de disnea, precordialgia y restricción física derivadas de isquemia de miocardio. En relación a limitaciones para realización de actividades físicas, pacientes con diagnóstico de angina inestable mostraron mayor compromiso en la semana que antecedió a la internación, así como relataron la presencia de disnea y precordialgia con mayor frecuencia que en los pacientes infartados en situaciones tales como realizar grandes esfuerzos como, por ejemplo, caminar en pendiente ascendiente o muy rápido en el llano, hasta situaciones de reposo o pequeños esfuerzos

Clinical and psychosocial features of heart failure patients admitted for clinical decompensation

This study had the purpose to identify the sociodemographic and clinical profiles, history of hospitalizations due to Heart Failure (HF) and follow-ups (regular appointments, drug treatment, facilities and difficulties for follow-up) of patients admitted for clinical decompensation. Interviews were held with 61 patients, with average age of 58.1 (+/- 15.9) years, 3.5 (+/- 4.4) years of education and individual income of 1.3 (+/- 2.4) times the minimum wage. Most subjects were in functional classes III or IV of the New York Heart Association, having signs and symptoms of the congestive form of HF as the most frequent cause of hospitalization. Of all subjects, 75.4% reported clinical follow-ups, although they tended to be irregular. The use of drug therapy occurred in lower ratios than that recommended in the literature. The findings must help to identify patients with higher risk of HC decompensation, and, as such, design and implement specific interventions aiming at reducing re-admittances due to HF.431414

Psychometric properties of the Minnesota Living with Heart Failure - Brazilian version - in the elderly

Background Heart failure (HF) has implications for the quality of life for any age range, more so for the elderly who simultaneously present other limitations imposed by multiple co-morbidities. Although there are several instruments to measure Health Related Quality of Life (HRQL), none is specific to the elderly with HF. Among disease-specific instruments, Minnesota Living with Heart Failure(LHFQ) has not been studied extensively among the elderly with respect to its psychometric properties. Objective The purpose of this study was to evaluate the convergent, divergent and discriminative validity of the Brazilian version of LHFQ applied to elderly HF patients. Method One hundred and seventy (170) elderly were interviewed. LHFQ capacity to discriminate subjects among New York Heart Association (NYHA) Classes I, II and III/IV was analyzed. Convergent and divergent validity was evaluated through the correlation between the domains of LHFQ and the generic instrument, Medical Outcomes Study (MOS) 36-item Short-Form Health Survey (SF-36). Results The LHFQ total score and physical dimension sub-scale discriminated between the three sub-groups of NYHA Classes I, II and III/IV (P < .0001). The emotional dimension discriminated NYHA Classes I and III/IV (P = .0034). The physical and emotional dimensions of the LHFQ and SF-36 were significantly correlated (coefficients from .46 to .70 for physical dimension and from .31 to .65 for emotional dimension). However, contrary to expectations, the divergent validity was not totally confirmed as there was no difference in the magnitude of the correlations between the LHFQ emotional and physical dimensions and the SF-36 role physical, social functioning and role emotional. Thus, the results suggest that LHFQ seems to be a valid tool to measure HRQL in the elderly, but new studies remain necessary to gain a better understanding of its discriminative validity for more advanced NYHA functional classes and for its divergent validity.166997100
