The Portuguese version of the Psychological Adjustment to Separation Test-Part A (PAST-A): a study with recently and non-recently divorced adults

Past research has demonstrated that divorced adults show more health problems and psychological distress than married adults. Considering the high prevalence rates of divorce among Western countries, new and robust measures should be developed to measure psychological distress after this specific transition in adulthood. The aim of this study was to adapt and validate a Portuguese version of the Psychological Adjustment to Separation Test-Part A (PAST-A; Sweeper and Halford in J Family Psychol 20(4):632–640, 2006). PAST-A is a self-report measure that assesses two key dimensions of separation adjustment problems: lonely-negativity and former partner attachment. Psychometric properties of the Portuguese version of PAST-A were assessed in terms of factor structure, internal consistency, and convergent and divergent validity, in an online convenience sample with divorced adults (N = 460). The PAST-A two-factor structure was confirmed by exploratory and confirmatory factor analyses, with each factor demonstrating very satisfactory internal consistency and good convergence. In terms of discriminant validity, the Portuguese PAST-A reveals a distinct factor from psychological growth after divorce. The results provided support for the use of the Portuguese PAST-A with divorced adults and also suggested that the explicative factors of the psychological adjustment to divorce may be cross-cultural stable. The non-existence of validated divorce-related well-being measures and its implications for divorce research are also discussed.

Retrospective Study of the Survival of Patients who Underwent Cardiopulmonary Resuscitation in an Intensive Care Unit

OBJECTIVE: To evaluate clinical and evolutive characteristics of patients admitted in an intensive care unit after cardiopulmonary resuscitation, identifying prognostic survival factors.METHODS: A retrospective study of 136 patients admitted between 1995 and 1999 to an intensive care unit, evaluating clinical conditions, mechanisms and causes of cardiopulmonary arrest, and their relation to hospital mortality.RESULTS: A 76% mortality rate independent of age and sex was observed. Asystole was the most frequent mechanism of death, and seen in isolation pulmonary arrest was the least frequent. Cardiac failure, need for mechanical ventilation, cirrhosis and previous stroke were clinically significant (p<0.01) death factors.CONCLUSION: Prognostic factors supplement the doctor's decision as to whether or not a patient will benefit from cardiopulmonary resuscitation.

Can the Cardiopulmonary 6-Minute Walk Test Reproduce the Usual Activities of Patients with Heart Failure?

OBJECTIVE: The 6-minute walk test is an way of assessing exercise capacity and predicting survival in heart failure. The 6-minute walk test was suggested to be similar to that of daily activities. We investigated the effect of motivation during the 6-minute walk test in heart failure. METHODS: We studied 12 males, age 45±12 years, ejection fraction 23±7%, and functional class III. Patients underwent the following tests: maximal cardiopulmonary exercise test on the treadmill (max), cardiopulmonary 6-minute walk test with the walking rhythm maintained between relatively easy and slightly tiring (levels 11 and 13 on the Borg scale) (6EB), and cardiopulmonary 6-minute walk test using the usual recommendations (6RU). The 6EB and 6RU tests were performed on a treadmill with zero inclination and control of the velocity by the patient. RESULTS: The values obtained in the max, 6EB, and 6RU tests were, respectively, as follows: O2 consumption (ml.kg-1.min-1) 15.4±1.8, 9.8±1.9 (60±10%), and 13.3±2.2 (90±10%); heart rate (bpm) 142±12, 110±13 (77±9%), and 126±11 (89±7%); distance walked (m) 733±147, 332±66, and 470±48; and respiratory exchange ratio (R) 1.13±0.06, 0.9±0.06, and 1.06±0.12. Significant differences were observed in the values of the variables cited between the max and 6EB tests, the max and 6RU tests, and the 6EB and 6RU tests (p<0.05). CONCLUSION: Patients, who undergo the cardiopulmonary 6-minute walk test and are motivated to walk as much as they possibly can, usually walk almost to their maximum capacity, which may not correspond to that of their daily activities. The use of the Borg scale during the cardiopulmonary 6-minute walk test seems to better correspond to the metabolic demand of the usual activities in this group of patients.

Unsupervised Rehabilitation: effects of Exercise Training over the Long Run

OBJECTIVE: To assess the safety and efficacy of unsupervised rehabilitation (USR) in the long run in low-risk patients with coronary artery disease. METHODS: We carried out a retrospective study with 30 patients divided into: group I (GI) - 15 patients from private clinics undergoing unsupervised rehabilitation; group II (GII) - control group, 15 patients from ambulatory clinic basis, paired by age, sex, and clinical findings. GI was stimulated to exercise under indirect supervision (jogging, treadmill, and sports). GII received the usual clinical treatment. RESULTS: The pre- and postobservation values in GI were, respectively: VO2peak (mL/kg/min), 24±5 and 31± 9; VO2 peak/peak HR: 0.18±0.05 and 0.28±0.13; peak double product (DP peak):26,800±7,000 and 29,000 ± 6,500; % peak HR/predicted HRmax: 89.5±9 and 89.3±9. The pre- and post- values in GII were: VO2 peak (mL/kg/min), 27± 7 and 28±5; VO2 peak/peak HR: 0.2±0.06 and 0.2± 0.05; DP peak: 24,900±8,000 and 25,600± 8,000, and % peak HR/predicted HRmax: 91.3±9 and 91.1± 11. The following values were significant: preobservation VO2peak versus postobservation VO2peak in GI (p=0.0 063); postobservation VO2peak in GI versus postobservation VO2peak in GII (p=0.0045); postobservation VO2 peak/peak HR GI versus postobservation peak VO2/peak HR in GII (p=0.0000). The follow-up periods in GI and GII were, respectively, 41.33± 20.19 months and 20.60±8.16 months (p<0.05). No difference between the groups was observed in coronary risk factors, therapeutic management, or evolution of ischemia. No cardiovascular events secondary to USR were observed in 620 patient-months. CONCLUSION: USR was safe and efficient, in low-risk patients with coronary artery disease and provided benefits at the peripheral level.

Frequency of hypertension in chronic Chagas' disease: retrospective clinical study

OBJECTIVE: To assess the frequency of hypertension in chagasic patients, as well as its clinical behavior and cardiologic findings. METHODS: We carried out a retrospective study with 225 patients with chronic Chagas' disease and hypertension (104 males), mean age of 55.1 ± 11.8. These patients were being followed up in the outpatient care clinics from 1984 to 2000. The study assessed the clinical, electrocardiographic, and radiological viewpoints. RESULTS: Of the 225 hypertensive patients (prevalence = 33.3%), 78 (34.7%) had mild hypertension, 108 (48%) had moderate hypertension, and 39 (17.3%) had severe hypertension. The association of left anterosuperior divisional block and right bundle-branch block occurred in 39 cases (17.3%), and enlargement of the cardiac area on radiological examination occurred in 93 (44.9%) of the 207 cases studied. The undetermined form of Chagas' disease was the most prevalent, 30.2% of the cases, followed by the form associated with conduction disorders in 27.1%, and the isolated form of conduction disorders in 21.3%. CONCLUSION: Chagasic patients had a frequency of hypertension similar to that of the general population, and the clinical profile of the hypertensive chagasic patients seemed not to differ a lot from that of the chagasic patients.

Creación de un test neuropsicológico de denominación confrontacional

La evaluación de la capacidad de denominar (encontrar las palabras adecuadas para nombrar objetos) tiene una importancia decisiva en el diagnóstico temprano de la enfermedad de Alzheimer ya que la anomia (pérdida de esta capacidad) es uno de los signos más tempranos de la enfermedad. Dicha evaluación también adquiere importancia en el diagnóstico de otras patologías tales como la demencia semántica o la afasia. Por lo tanto es importante contar con un test de denominación que sea adecuadamente diseñado para nuestro contexto cultural. Debido a que las pruebas de denominación creadas en otros contextos culturales no funcionan adecuadamente al aplicarse transculturalmente es que se comenzó, hace algunos años, a construir el Test de Denominación Córdoba. Éste es un test neuropsicológico para evaluar la capacidad de denominación confrontacional (implica la producción de los nombres correctos de figuras que se le presentan al individuo). Se diseñaron las láminas, y se realizó un estudio piloto para determinar el orden correcto de las mismas y eliminar láminas técnicamente inadecuadas. Luego se comenzaron los estudios de validez y la estandarización del test. En este proyecto se propone finalizar con los estudios de validez, confiabilidad y los baremos. Para ello se propone administrar alrededor de 200 tests a personas cognitivamente sanas para completar el baremo y alrededor de 20 a 25 personas con Enfermedad de Alzheimer para el estudio de validez

Desarrollo de un test de detección temprana de trastornos de aprendizaje- test de velocidad de denominación.

La evaluación de la velocidad de denominación permite la identificación temprana de niños en riesgo de desarrollar dislexia. Por lo tanto es importante contar con un test de velocidad de denominación que sea adecuadamente diseñado para nuestro contexto cultural. Debido a que las pruebas de denominación creadas en otros contextos culturales no funcionan adecuadamente al aplicarse transculturalmente, es que se propone construir el Test de Velocidad de Denominación. Éste es un test neuropsicológico para evaluar la velocidad de denominación (implica cronometrar el tiempo necesario para la producción de los nombres correctos de figuras que se le presentan al individuo). Se diseñarán las láminas y se realizará un estudio piloto para determinar las figuras más adecuadas a incluir. Luego se realizará un estudio de validez del test. Para completar ambos estudios se propone administrar alrededor de cincuenta tests a niños en edad pre-escolar (cuatro y cinco años) para el estudio de diseño de las láminas; y a alrededor de cien niños de primer a tercer grado se les administrará el Test de Velocidad de Denominación y dos subtests de la batería de lectura LEE, para el estudio de validez.

Construcción de un Test de Conocimiento General. Development of a General Knowledge Test

Entre los factores que contribuyen a predecir el rendimiento académico se pueden destacar aquellos que reflejan capacidades cognitivas (inteligencia, por ejemplo), y aquellas diferencias individuales consideradas como no-cognitivas (rasgos de personalidad, por ejemplo). En los últimos años, también se considera al Conocimiento General (CG) como un criterio para el éxito académico (ver Ackerman, 1997), ya que se ha evidenciado que el conocimiento previo ayuda en la adquisición de nuevo conocimiento (Hambrick & Engle, 2001). Uno de los objetivos de la psicología educacional consiste en identificar las principales variables que explican el rendimiento académico, como también proponer modelos teóricos que expliquen las relaciones existentes entre estas variables. El modelo teórico PPIK (Inteligencia-como-Proceso, Personalidad, Intereses e Inteligencia-como-Conocimiento) propuesto por Ackerman (1996) propone que el conocimiento y las destrezas adquiridas en un dominio en particular son el resultado de la dedicación de recursos cognitivos que una persona realiza durante un prolongado período de tiempo. Este modelo propone que los rasgos de personalidad, intereses individuales/vocacionales y aspectos motivacionales están integrados como rasgos complejos que determinan la dirección y la intensidad de la dedicación de recursos cognitivos sobre el aprendizaje que realiza una persona (Ackerman, 2003). En nuestro medio (Córdoba, Argentina), un grupo de investigadores ha desarrollado una serie de recursos técnicos necesarios para la evaluación de algunos de los constructos propuesto por este modelo. Sin embargo, por el momento no contamos con una medida de Conocimiento General. Por lo tanto, en el presente proyecto se propone la construcción de un instrumento para medir Conocimiento General (CG), indispensable para poder contar con una herramienta que permita establecer parámetros sobre el nivel de conocimiento de la población universitaria y para en próximos trabajos poner a prueba los postulados de la teoría PPIK (Ackerman, 1996). Between the factors that contribute to predict the academic achievement, may be featured those who reflect cognitive capacities (i.g. intelligence) and those who reflect individual differences that are considered like non-cognitive (i.g. personality traits). In the last years, also the General Knowledge has been considered like a criterion for the academic successfully (see Ackerman, 1997), since it has been shown that the previous knowledge helps in the acquisition of the new knowledge (Hambrick & Engle, 2001). An interesting theoretical model that has proposed an explanation for the academic achievement, is the PPIK (intelligence like a process, interests and inteligence like knowledge) proposed by Ackerman (1996), who argues that knowledge and the acquired skills in a particular domain are the result of the dedication of cognitive resources that a person perform during a long period of time. This model proposes that personality traits, individuals interests and motivational aspects are integrated as complex traits that determine the direction and the intensity of the dedication of cognitive resources on the learning that a person make (Ackerman, 2003). In our context, (Córdoba, Argentina), a group of researcher has developed a series of necessary technical resoures for the assesment of some of the theoretical constructs proposed by this model. However, by the moment, we do not have an instrument for evaluate the General Knowledge. Therefore, this project aims the construction of an instrument to asess General Knowledge, essential to set parameters on the knowledge level of the university population and for in next works test the PPIK theory postulates.

Estandarización y confiabilidad del test de velocidad de denominación para la detección temprana de dislexia.

La evaluación de la velocidad de denominación permite la identificación temprana de niños en riesgo de desarrollar dislexia. Por lo tanto es importante contar con un test de velocidad de denominación que sea adecuadamente diseñado para nuestro contexto cultural. Debido a que las pruebas de denominación creadas en otros contextos culturales no funcionan adecuadamente al aplicarse transculturalmente es que se construyó el Test de Velocidad de Denominación. Éste es un test neuropsicológico para evaluar la velocidad de denominación (implica cronometrar el tiempo necesario para la producción de los nombres correctos de figuras que se le presentan al individuo). El test consta con satisfactorios estudios de validez. Para la presente etapa se propone administrar el test a doscientos niños de 4 a 8 años para la construcción del baremo. A una submuestra de sesenta niños del grupo de baremación se les readministrará el test a los fines de evaluar la confiabilidad (estabilidad) de la prueba.

Teste de inclinação (Tilt-test): do necessário ao imprescindível

O teste de inclinação (TI) é muito utilizado para a investigação de síncopes e pré-síncopes, pois possibilita o diagnóstico de diferentes tipos de disautonomias. A principal causa de síncope é a Síndrome Vasovagal, cujo diagnóstico é o mais frequente entre as indicações de TI. O exame é utilizado há cerca de 20 anos, mas muitos médicos desconhecem a metodologia. São importantes a indicação apropriada, após exclusão de causas cardíacas de síncope, e a orientação do paciente para garantir a tranquilidade e a segurança do teste. Existem controvérsias na literatura sobre a capacidade diagnóstica e a confiabilidade dos resultados. Os estudos com protocolos diversos podem explicar a variabilidade dos resultados. Nesta revisão, são colocadas as indicações e a metodologia recomendadas pelas diretrizes, complicações, limitações e perspectivas desse exame.

Investigation Route of the Coronary Patient in the Public Health System in Curitiba, São Paulo and in Incor - IMPACT Study

Background: The investigation of stable coronary artery disease (CAD) and its treatment depend on risk stratification for decision-making on the need for cardiac catheterization and revascularization. Objective: To analyze the procedures used in the diagnosis and invasive treatment of patients with CAD, at the Brazilian Unified Health System (SUS) in the cities of Curitiba, São Paulo and at InCor-FMUSP. Methods: Retrospective, descriptive, observational study of the diagnostic and therapeutic itineraries of the Brazilian public health care system patient, between groups submitted or not to prior noninvasive tests to invasive cardiac catheterization. Stress testing, stress echocardiography, perfusion scintigraphy, catheterization and percutaneous or surgical revascularization treatment procedures were quantified and the economic impact of the used strategies. Results: There are significant differences in the assessment of patients with suspected or known CAD in the metropolitan region in the three scenarios. Although functional testing procedures are most often used the direct costs of these procedures differ significantly (6.1% in Curitiba, 20% in São Paulo and 27% in InCor-FMUSP). Costs related to the procedures and invasive treatments represent 59.7% of the direct costs of SUS in São Paulo and 87.2% in Curitiba. In InCor-FMUSP, only 24.3% of patients with stable CAD submitted to CABG underwent a noninvasive test before the procedure. Conclusion: Although noninvasive functional tests are the ones most often requested for the assessment of patients with suspected or known CAD most of the costs are related to invasive procedures/treatments. In most revascularized patients, the documentation of ischemic burden was not performed by SUS.

4-Second Exercise Test: Reference Values for Ages 18–81 Years

Background: Physiological reflexes modulated primarily by the vagus nerve allow the heart to decelerate and accelerate rapidly after a deep inspiration followed by rapid movement of the limbs. This is the physiological and pharmacologically validated basis for the 4-s exercise test (4sET) used to assess the vagal modulation of cardiac chronotropism. Objective: To present reference data for 4sET in healthy adults. Methods: After applying strict clinical inclusion/exclusion criteria, 1,605 healthy adults (61% men) aged between 18 and 81 years subjected to 4sET were evaluated between 1994 and 2014. Using 4sET, the cardiac vagal index (CVI) was obtained by calculating the ratio between the duration of two RR intervals in the electrocardiogram: 1) after a 4-s rapid and deep breath and immediately before pedaling and 2) at the end of a rapid and resistance-free 4-s pedaling exercise. Results: CVI varied inversely with age (r = -0.33, p < 0.01), and the intercepts and slopes of the linear regressions between CVI and age were similar for men and women (p > 0.05). Considering the heteroscedasticity and the asymmetry of the distribution of the CVI values according to age, we chose to express the reference values in percentiles for eight age groups (years): 18–30, 31–40, 41–45, 46–50, 51–55, 56–60, 61–65, and 66+, obtaining progressively lower median CVI values ranging from 1.63 to 1.24. Conclusion: The availability of CVI percentiles for different age groups should promote the clinical use of 4sET, which is a simple and safe procedure for the evaluation of vagal modulation of cardiac chronotropism.

Myocardial Scintigraphy in the Evaluation of Cardiac Events in Patients without Typical Symptoms

AbstractBackground:Cardiovascular disease is a leading cause of death in the world and in Brazil. Myocardial scintigraphy is an important noninvasive method for detecting ischemia in symptomatic patients, but its use in asymptomatic ones or those with atypical symptoms is yet to be defined.Objective:To verify the presence of major cardiac events in asymptomatic patients or those with atypical symptoms (atypical chest pain or dyspnea) that underwent myocardial scintigraphy (MS), over a period of 8 years. Secondary objectives were to identify cardiac risk factors associated with myocardial scintigraphy abnormalities and possible predictors for major cardiac events in this group.Methods:This was a retrospective, observational study using the medical records of 892 patients that underwent myocardial scintigraphy between 2005 and 2011 and who were followed until 2013 for assessment of major cardiac events and risk factors associated with myocardial scintigraphy abnormalities. Statistical analysis was performed by Fisher’s exact test, logistic regression and Kaplan-Meyer survival curves, with statistical significance being set at p ≤ 0.05.Results:Of the total sample, 52.1% were men, 86.9% were hypertensive, 72.4% had hyperlipidemia, 33.6% were diabetic, and 12.2% were smokers; 44.5% had known coronary artery disease; and 70% had high Framingham score, 21.8% had moderate and 8% had low risk. Of the myocardial scintigraphies, 58.6% were normal, 26.1% suggestive of fibrosis and 15.3% suggestive of ischemia. At evolution, 13 patients (1.5%) had non-fatal myocardial infarction and six individuals (0.7%) died. The group with normal myocardial scintigraphy showed longer period of time free of major cardiac events, non-fatal myocardial infarction (p = 0.036) and death. Fibrosis in the myocardial scintigraphy determined a 2.4-fold increased risk of non-fatal myocardial infarction and five-fold higher risk of death (odds ratio: 2.4 and 5.7, respectively; p = 0.043).Conclusion:The occurrence of major cardiac events in 8 years was small. Patients with fibrosis at MS had more major events, whereas patients with normal MS result had fewer major cardiac events, with higher survival.
