Functional Assessment of Cancer Therapy Bone Marrow Transplantation: tradução e validação

OBJETIVO: Traduzir para o português e validar o questionário de qualidade de vida Functional Assessment of Cancer Therapy - Bone Marrow Transplantation (FACT-BMT) em pacientes transplantados de medula óssea. OBJETIVO: O estudo foi realizado em Ribeirão Preto, SP, em 2005. O FACT-BMT (versão 3) traduzido e a versão em português do Short Form-36 Health Survey (SF-36) foram aplicados simultaneamente em 55 pacientes consecutivos com leucemia, submetidos ao transplante e em seguimento. Dois parâmetros clínicos foram utilizados para testar a sensibilidade do questionário: tempo decorrido do transplante e presença ou não de doença do enxerto contra o hospedeiro. Foi utilizada a análise de variância (ANOVA) com o teste post hoc de Tukey. Aplicou-se o coeficiente alfa de Cronbach, padronizado para todas as questões, escore final e domínios. RESULTADOS: A média de idade dos pacientes foi 34,8±8,1 anos, com escolaridade média de 10,8±4,7 anos, sendo 78,1% do sexo feminino. A duração média de tempo pós-transplante foi de 29,8±32,19 meses. Nenhuma alteração do formato original do questionário foi observada no final do processo de tradução e adaptação cultural. A consistência interna foi alta (0,88). A correlação entre o questionário traduzido e o SF-36 variou de 0,35 a 0,57, considerada de moderada a boa para a maioria dos domínios de qualidade de vida. A avaliação das validades de construto e concorrente foi satisfatória e estatisticamente significativa. CONCLUSÕES: A versão para o português do FACT-BMT foi validada satisfatoriamente para a aplicação em pacientes brasileiros de ambos os sexos submetidos ao transplante de medula óssea.

Functional magnetic resonance imaging in oncology: state of the art

In the investigation of tumors with conventional magnetic resonance imaging, both quantitative characteristics, such as size, edema, necrosis, and presence of metastases, and qualitative characteristics, such as contrast enhancement degree, are taken into consideration. However, changes in cell metabolism and tissue physiology which precede morphological changes cannot be detected by the conventional technique. The development of new magnetic resonance imaging techniques has enabled the functional assessment of the structures in order to obtain information on the different physiological processes of the tumor microenvironment, such as oxygenation levels, cellularity and vascularity. The detailed morphological study in association with the new functional imaging techniques allows for an appropriate approach to cancer patients, including the phases of diagnosis, staging, response evaluation and follow-up, with a positive impact on their quality of life and survival rate.

Fatores associados a quedas em uma coorte de idosos residentes na comunidade

OBJETIVO: Identificar fatores associados a quedas e a quedas recorrentes em idosos vivendo na comunidade, determinando o risco relativo de cada fator como preditor para quedas. MÉTODOS: Trata-se de um estudo de seguimento de dois anos, por meio de duas ondas de inquéritos multidimensionais domiciliares (1991/92 e 1994/95) com uma coorte de 1.667 idosos de 65 anos ou mais residentes na comunidade, município de São Paulo, SP. O instrumento utilizado foi um questionário estruturado, versão brasileira do OARS: Brazilian Multidimensional Functional Assessment Questionnaire (BOMFAQ). Foi realizada uma análise de regressão logística, passo a passo, com p<0,05 e IC de 95%. RESULTADOS: Cerca de 31% dos idosos disseram ter caído no ano anterior ao primeiro inquérito; cerca de 11% afirmaram ter sofrido duas ou mais quedas. Durante o seguimento, 53,4% dos idosos não referiram quedas, 32,7% afirmaram ter sofrido queda em pelo menos um dos inquéritos e 13,9% relataram quedas em ambos os inquéritos. O modelo preditivo de quedas recorrentes foi composto das variáveis: ausência de cônjuge (OR=1,6 95% IC 1,00-2,52), não ter o hábito de ler (OR=1,5 95% IC 1,03-2,37), história de fratura (OR=4,6 95% CI 2,23-9,69), dificuldade em uma a três atividades de vida diária (OR=2,37 95% CI 1,49-3,78), dificuldade em quatro ou mais atividades de vida diária (OR=3,31 95% CI 1,58-6,93) e entre aqueles idosos com visão mais comprometida (OR=1,53 95% CI 1,00-2,34). CONCLUSÕES: O envelhecimento populacional e o aumento da expectativa de vida demandam ações preventivas e reabilitadoras no sentido de diminuir os fatores de risco para quedas, como o comprometimento da capacidade funcional, a visão deficiente e a falta de estimulação cognitiva.

Doppler echocardiographic study in adolescents and young adults with sickle cell anemia

OBJECTIVE: Anatomical and functional assessment of the heart through Doppler and echocardiography in patients with cell anemia (SCA). METHODS: Twenty-five patients with SCA and ages ranging from 14 to 45 years were prospectively studied in a comparison with 25 healthy volunteers. All of them underwent clinical and laboratory evaluation and Doppler echocardiography as well.The measurements were converted into body surface indices. RESULTS: There were increases in all chamber diameters and left ventricle (LV) mass of the SCA patients. It was characterised an eccentric hypertrophy of the left ventricle. The preload was increased (left ventricle end-diastolic volume) and the afterload was decreased (diastolic blood pressure, peripheral vascular resistance and end-systolic parietal stress ESPS). The cardiac index was increased due to the stroke volume. The ejection fraction and the percentage of the systolic shortening , as well as the systolic time intervals of the LV were equivalent. The isovolumetric contraction period of the LV was increased. The mitral E-septum distance and the end-systolic volume index (ESVi) were increased. The ESPS/ESVi ratio,a loading independent parameter, was decreased in SCA, suggesting systolic dysfunction. No significant differences in the diastolic function or in the pulmonary pressure occurred. CONCLUSION: Chamber dilations, eccentric hypertrophy and systolic dysfunction confirm the evidence of the literature in characterizing a sickle cell anemia cardiomyopathy.

Obesity Preserves Myocardial Function During Blockade of the Glycolytic Pathway

Background: Obesity is defined by excessive accumulation of body fat relative to lean tissue. Studies during the last few years indicate that cardiac function in obese animals may be preserved, increased or diminished. Objective: Study the energy balance of the myocardium with the hypothesis that the increase in fatty acid oxidation and reduced glucose leads to cardiac dysfunction in obesity. Methods: 30-day-old male Wistar rats were fed standard and hypercaloric diet for 30 weeks. Cardiac function and morphology were assessed. In this paper was viewed the general characteristics and comorbities associated to obesity. The structure cardiac was determined by weights of the heart and left ventricle (LV). Myocardial function was evaluated by studying isolated papillary muscles from the LV, under the baseline condition and after inotropic and lusitropic maneuvers: myocardial stiffness; postrest contraction; increase in extracellular Ca2+ concentration; change in heart rate and inhibitor of glycolytic pathway. Results: Compared with control group, the obese rats had increased body fat and co-morbities associated with obesity. Functional assessment after blocking iodoacetate shows no difference in the linear regression of DT, however, the RT showed a statistically significant difference in behavior between the control and the obese group, most notable being the slope in group C. Conclusion: The energy imbalance on obesity did not cause cardiac dysfunction. On the contrary, the prioritization of fatty acids utilization provides protection to cardiac muscle during the inhibition of glycolysis, suggesting that this pathway is fewer used by obese cardiac muscle.

Este estudo objetivou descrever as características sociodemográficas e a qualidade de vida dos cuidadores de idosos com histórico de acidente vascular cerebral e correlacionar o número de morbidades com os escores de qualidade de vida do cuidador. Inquérito domiciliar transversal que entrevistou cuidadores de idosos utilizando-se de instrumentos: semi-estruturado; World Health Organization Quality of Life-abreviado e Brazilian Multidimensional Functional Assessment Questionnaire. Foi realizada análise descritiva e correlação de Pearson (p<0,05). Prevaleceu o sexo feminino (93,5%), idade média de 55,4±14,17 anos, casados ou moram com companheiro (58,7%), com 4| - 8 anos de estudo (28,3%) e renda de 1 salário mínimo (34,8%). O maior escore de qualidade de vida foi no domínio relações sociais (67,57) e, menor no meio ambiente (54,82). O maior número de morbidades do cuidador correlacionou-se com menores escores em todos os domínios de qualidade de vida.

Chest magnetic resonance imaging: a protocol suggestion

Abstract In the recent years, with the development of ultrafast sequences, magnetic resonance imaging (MRI) has been established as a valuable diagnostic modality in body imaging. Because of improvements in speed and image quality, MRI is now ready for routine clinical use also in the study of pulmonary diseases. The main advantage of MRI of the lungs is its unique combination of morphological and functional assessment in a single imaging session. In this article, the authors review most technical aspects and suggest a protocol for performing chest MRI. The authors also describe the three major clinical indications for MRI of the lungs: staging of lung tumors; evaluation of pulmonary vascular diseases; and investigation of pulmonary abnormalities in patients who should not be exposed to radiation.

Exercícios para membros superiores durante radioterapia para câncer de mama e qualidade de vida

OBJETIVO: avaliar a influência da fisioterapia realizada durante a radioterapia (RT) sobre a qualidade de vida (QV) de mulheres em tratamento para câncer de mama. MÉTODOS: ensaio clínico randomizado com 55 mulheres em tratamento radioterápico, sendo 28 alocadas no grupo submetido à fisioterapia (GF) e 27 no grupo controle sem fisioterapia (GC). A técnica fisioterápica utilizada para o GF foi a cinesioterapia para membros superiores, com emprego de 19 exercícios realizados ativamente, com uma série de dez repetições rítmicas ou alongamentos, englobando movimentos de flexão, extensão, abdução, adução, rotação interna e rotação externa dos ombros, isolados ou combinados. A QV foi avaliada por meio do Functional Assessment of Cancer Therapy-Breast (FACT-B) no início, no final da RT e seis meses após seu término. As sessões de fisioterapia começavam concomitantemente à RT, em média 90 dias após a cirurgia. RESULTADOS: não houve diferença entre os grupos para as subescalas: bem-estar físico (p=0,8), bem-estar social/familiar (p=0,3), bem-estar funcional (p=0,2) e subescala de mama (p=0,2) nos três momentos avaliados. A comparação da subescala emocional obtida nas três avaliações demonstrou melhor comportamento do GF em relação ao GC (p=0,01). Ambos apresentaram melhora na subescala de mama entre o início e final da RT (GF p=0,0004 e GC p=0,003). Houve melhora dos escores do FACT-B ao final da RT em ambos os grupos (GF p=0,0006 e GC p=0,003). No entanto, seis meses após a RT, esta melhora manteve-se somente no GF (p=0,005). A qualidade de vida avaliada ao longo do tempo pelo FACT B (p=0,004) e Trial Outcome Index (TOI) (soma das subescalas bem-estar físico, funcional e subescala de mama) foi melhor no GF (p=0,006). Não houve evidência de efeitos negativos associados aos exercícios. CONCLUSÕES: a realização de exercícios para membros superiores beneficiou a qualidade de vida durante e seis meses após a RT.

Assessment of functional capacity through oxygen consumption in patients with asymptomatic probable heart disease

PURPOSE: To compare peak exercise oxygen consumption (VO2peak) of healthy individuals with asymptomatic individuals with probable heart disease. METHODS: Ninety-eight men were evaluated. They were divided into two groups: 1) 39 healthy individuals (group N) with an age range of 50±4.6 years; and 2) 59 asymptomatic individuals with signs of atherosclerotic and/or hypertensive heart disease (group C) with an age range of 51.9±10.4 years. In regard to age, height, body surface area, percentage of fat, lean body mass, and daily physical activity, both groups were statistically similar. Environmental conditions during the ergometric test were also controlled. RESULTS: Maximal aerobic power (watts), VO2peak, maximal heart rate, and maximal pulmonary ventilation were lower in group C (p<0.01) than in group N; weight, however, was lower in group N (p=0.031) than in group C. Differences in the respiratory gas exchange index, heart rate at rest, and the maximal double product of the two groups were not statistically significant. CONCLUSION: Signs of probable heart disease, even though asymptomatic, may reduce the functional capacity, perhaps due to the lower maximal cardiac output and/or muscle metabolic changes.

Biomarkers for the assessment of chlorpyrifos effects on earthworms and on soil functional parameters

The objective of this work was to evaluate the effects of chlorpyrifos on earthworms and on soil functional parameters. An integrated laboratory-field study was performed in a wheat field in Argentina, sprayed with chlorpyrifos at two recommended application rates (240 or 960 g ha-1 style='vertical-align:baseline'> a.i.). Laboratory tests included neutral red retention time, comet assay (single cell gel electrophoresis), and avoidance behavior, each using the earthworm Eisenia andrei exposed in soil collected 1 or 14 days after pesticide application, and the bait-lamina test. Field tests assessed organic matter breakdown using the litterbag and bait-lamina assays. Earthworm populations in the field were assessed using formalin application and hand-sorting. The neutral red retention time and comet assays were sensitive biomarkers to the effects of chlorpyrifos on the earthworm E. andrei; however, the earthworm avoidance test was not sufficiently robust to assess these effects. Feeding activity of soil biota, assessed by the bait lamina test, was significantly inhibited by chlorpyrifos after 97 days, but recovered by the 118th day of the test. Litterbag test showed no significant differences in comparison to controls. Earthworm abundance in the field was too low to adequately test the sensitivity of this assessment endpoint.

Clinical and functional aspects of work-related musculoskeletal disorders among active workers

OBJECTIVE: To evaluate musculoskeletal disorders among active industrial workers. METHODS: The study was carried out in São Carlos, Southeastern Brazil, in 2005. One hundred and thirty-four female workers were physically evaluated and answered questions about their physical symptoms, filled out a pain scale and gave responses in the Oswestry Disability Questionnaire, and the Work Ability Index questionnaire. The data were analyzed descriptively, and in correlation tests and through applying logistic regression. The outcome was evaluated in relation to the perceptions of pain, symptoms, physical assessment, ability to work and disability. RESULTS: Clinical evaluations and sick leave presented positive correlations with the subjective variables. The Work Ability Index presented a negative correlation with the physical disability index (r=-0.69). Symptoms reported at the time of the assessment presented a good correlation with the results from the pain scale and the clinical findings. Previous sick leave showed an association with disability (OR=1.13; 95% CI:1.08;1.18). CONCLUSION: Symptom reports and pain scales may be useful for assessing current conditions at the time of evaluating individuals with work-related musculoskeletal disorders, as they are easier to apply. In more severe cases of such injuries, clinical and functional evaluations and questionnaires such as those relating to ability to work and disability are preferable. Precise and specific evaluations of these disorders may contribute towards fairer legal and administrative decisions.

Forensic neuropsychological assessment: clinical case of depression and working incapacity

Issues related to mental health in relation to court matters have increasingly required the participation of the psychologist. We present the use of forensic neuropsychological assessment in a case of retirement reversal. Incapacity was attested due to disability resulting from depression of a 35-year-old attorney, and the case was forwarded from the courts to the Forensic Psychiatry and Psychology Unit at the USP Clinical Hospital. A clinical interview and application of cognitive tests was conducted. Despite the depression, significant cognitive losses that would prevent return to his professional assignments were not detected. The neuropsychological assessment has been shown to be an important tool in the forensic context, as it assists with diagnostic value for clarification of functional aspects in the various psychopathological areas in terms of disabilities or potentialities.

Critical aortic stenosis in the neonate. Clinical assessment and surgical outcome in 18 patients

OBJECTIVE - To assess neonates with aortic stenosis with early decompensation operated upon. (LCO) (CHF). METHODS - A and retrospective study analyzing 6 neonates with LCO, group I (GI), and 12 neonates with CHF, group II (GII). Clinical radiographic, electrocardiographic and echocardiographic findings also provided comparative bases for the study, as did surgical and evolutional findings. RESULTS - The mean ages at hospitalization and surgery (p = 0.0031) were 14.3 and 14.8 days in GI and 35.4 and 42.8 days in GII, respectively. Cardiac murmurs were more intense in GII (p = 0.0220). The aortic ring was smaller in GI (8.0 ± 2.5mm) as compared to GII (11.4±1.4mm) (p = 0.2882). Ventricular function was reduced to 18±5.5% and 33.3±7.6% in GI and GII, respectively (p = 0.0162). Aortic atresia, however, was present only in 2 neonates in GI. Five of 6 patients in GI died but all patients in GII survived (p=0.0007). In the latter group, 84.6% of the patients were in functional class I (FC-I) in the long-term follow-up, with moderate residual lesions in 6 neonates, discrete residual lesions in 4, and reoperation in 2. CONCLUSION - Aortic stenosis is a severe anomaly of the neonate, whose immediate evolution depends on the pre-operative anatomic and functional findings, and the late evolution essentially depends on the anatomic features of the valve.

Clinical and pathological assessment of 82 patients with cardiovascular diseases undergoing autopsy at the Hospital das Clínicas of the Faculdade de Medicina de Botucatu from 1988 to 1993

OBJECTIVE: To evaluated the clinical diagnostic, efficiency for basic death causes in patients dying of circulatory disease and de relative frequency of those diseases. METHODS: Analysis of medical record data of 82 patients, ages from 16 to 84 years old (68 over 40 years old), whose died of circulatory disease and had undergone necropsy in the period from 1988 to 1993 years in the University Hospital of Medicine Faculty of Botucatu-UNESP, Br. RESULTS: The functional class of patients were III or IV, in 78%, and 81.7% needed urgent hospitalization. By the clinical judgment the death were by ischemic heart disease in 32 (21 acute myocardial infarction), Chagas'disease in 12, valvopathy in 11, cardiomyopathy in 7, heart failure with no specification of cardiopathy in 11 and other causes in 9. At the necropsy the death cause was ischemic heart disease in 34 patients, valvopathy in 10, Chagas'disease in 10, cardiomyopathy in 5, and heart failure with no specification of cardiopathy in 2.The concordance taxes were in thhe same order: 94,6%, 90,0%, 83.3%, 71.4% and 28.5%. CONCLUSION: There was a great efficiency of clinical diagnosis for death cause in a general university hospital. The ischemic heart disease were the main causes of death.
