Sintomas depressivos no câncer de mama: Inventário de Depressão de Beck - Short Form

OBJETIVOS: Verificar a prevalência de sintomas depressivos em mulheres com câncer de mama e identificar os fatores de risco associados à sua ocorrência. MÉTODOS: Foi realizado um estudo transversal, em que foram entrevistadas 71 mulheres com câncer de mama. Foram empregados dois instrumentos: um questionário para verificar os dados sociodemográficos e clínicos e o Inventário de Depressão de Beck - Short Form (BDI-SF), para avaliação dos sintomas depressivos. Para análise dos dados, utilizaram-se medidas descritivas e o teste de qui-quadrado, que avaliou a associação entre variáveis sociodemográficas e clínicas e os sintomas depressivos. O nível de significância considerado foi de 5%. RESULTADOS: A prevalência de sintomas depressivos foi de 29,6%. Os fatores associados à presença desses sintomas foram o tratamento quimioterápico (p = 0,021), presença de dor (p = 0,018) e limitação do movimento do membro superior (p = 0,010) e pior percepção da saúde (p = 0,018). CONCLUSÃO: Sintomas depressivos são frequentes no câncer de mama, assim a saúde mental das mulheres com esse tipo de câncer deve ser investigada e tratada quando necessário, reduzindo o impacto desses sintomas na vida da mulher.

Permanent and temporary pacemaker implantation after orthotopic heart transplantation

PURPOSE:To determine the indication for and incidence and evolution of temporary and permanent pacemaker implantation in cardiac transplant recipients. METHODS: A retrospective review of 114 patients who underwent orthotopic heart transplantation InCor (Heart Institute USP BR) between March 1985 and May 1993. We studied the incidence of and indication for temporary pacing, the relationship between pacing and rejection, the need for pemanent pacing and the clinical follow-up. RESULTS: Fourteen of 114 (12%)heart transplant recipients required temporary pacing and 4 of 114 (3.5%) patients required permanent pacing. The indication for temporary pacing was sinus node dysfunction in 11 patients (78.5%) and atrioventricular (AV) block in 3 patients (21.4%). The indication for permanent pacemaker implantation was sinus node dysfunction in 3 patients (75%) and atrioventricular (AV) block in 1 patient (25%). We observed rejection in 3 patients (21.4%) who required temporary pacing and in 2 patients (50%) who required permanent pacing. The previous use of amiodarone was observed in 10 patients (71.4%) with temporary pacing. Seven of the 14 patients (50%) died during follow-up. CONCLUSION: Sinus node dysfunction was the principal indication for temporary and permanent pacemaker implantation in cardiac transplant recipients. The need for pacing was related to worse prognosis after cardiac transplantation.

Psychometric properties of the Portuguese version of the Posttraumatic Growth Inventory Short Form among divorced adults

The aim of this study was to develop and validate a Portuguese version of the Short Form of the Posttraumatic Growth Inventory (PTGI-SF). Using an online convenience sample of Portuguese divorced adults (N = 482), we confirmed the oblique five-factor structure of the PTGI-SF by confirmatory factor analysis. The results demonstrated the measurement invariance across divorce initiator status groups. Total score and factors of PTGI-SF showed good internal consistency, with the exception of the New Possibilities factor, which revealed an acceptable reliability. The Portuguese PTGI-SF showed a satisfactory convergent validity. In terms of discriminant validity, posttraumatic growth assessed by the Portuguese PTGI-SF was a distinct factor from posttraumatic psychological adjustment. These preliminary findings suggest the cultural adaptation and also psychometric properties of the present Portuguese PTGI-SF to measure posttraumatic growth after personal crisis.

Pericardial Effusion with Cardiac Tamponade as a Form of Presentation of Primary Hypothyroidism

The authors describe a case of pericardial effusion accompanied by cardiac tamponade caused by primary hypothyroidism. Diagnosis was made by exclusion, because other causes of cardiac tamponade are more frequent. Emergency treatment of cardiac tamponade is pericardiocentesis (with possible pericardial window), and, after stabilization, performance of hormonal reposition therapy with L-thyroxin.

Marfan's syndrome: early and severe form in siblings

Marfan's syndrome is an inherited disorder of the connective tissue. Cardiologic manifestations, especially aortic dilation, are important causes of morbidity and mortality in the clinical course of the disease in adults and teenagers. In children, the presence of aortic aneurysm and its dissection or rupture is rare, occurring in patients with genetic mutation of the fibrillin gene but not in those who have the familial form of the disease. We describe here 2 patients, from the same family (siblings), diagnosed with gigantic aortic aneurysm early in infancy, one of them successfully undergoing surgery.

Right Ventricular Doppler Echocardiographic Study of Indeterminate Form of Chagas Disease

Background: Patients with indeterminate form of Chagas disease/cardiac normality (ICD/CN) exhibited normal electrocardiograms and chest X-rays; however, more sophisticated tests detected some degree of morphological and functional changes in the heart. Objective: To assess the prevalence of systolic and diastolic dysfunction of the right ventricle (RV) in patients with ICD/CN. Methods: This was a case–control and prevalence study. Using Doppler two-dimensional echocardiography (2D), 92 patients were assessed and divided into two groups: group I (normal, n = 31) and group II (ICD/CN, n = 61). Results: The prevalence of RV systolic dysfunction in patients in groups I and II was as follows: fractional area change (0.0% versus 0.6%), mobility of the tricuspid annulus (0.0% versus 0.0%), and S-wave tissue Doppler (6.4% versus 26.0%, p = 0.016). The prevalence of global disorders such as the right myocardial performance index using tissue Doppler (16.1% versus 27.8%, p = 0.099) and pulsed Doppler (61.3% versus 68%, p = 0.141) and diastolic disorders such as abnormal relaxation (0.0% versus 6.0%), pseudonormal pattern (0.0% versus 0.0%), and restrictive pattern (0.0% versus 0.0%) was not statistically different between groups. Conclusion: The prevalence of RV systolic dysfunction was estimated to be 26% (S wave velocity compared with other variables), suggesting incipient changes in RV systolic function in the ICD/CN group.

Nota prévia sôbre a meiose de Corizus (Liorhyssus) hyalinus (Fabr.) (Hemiptera-Corizidae)

The main facts presented in this paper may be summarized as follows: 1) Corizus (Liorhyssus) hyalinus (Fabr.) has primary spermatocytes provided with 6 autosomal tetrads, one pair of microchromosomes and one sex chromosome. 2) The two microchromosomes present in this species sometimes appear at the primary metaphase as an unequal pair of minute elements. In the secondary spermatocytes the unique microchromosome present may be in the limit of visibility or entirely invisible. This invisibility may be partly due to a loss of colourability. 3) The sex chromosome divides transversely in the first division of the spermatocyte, passing undivided to one pole in the second one. In the latter it becomes fusiform in the beginning of anaphase revealing in this manner its dicentricity. In late anaphase it finishes by passing to one pole leaving in the other pole one of its kinetochores sometimes accompanied by a chromosomal fragment. 4) All the chromosomes divide transversely in both divisions, a diagram being enclosed to elucidate the question. 5) Spermatogonial chromosomes are provided with one kinetochore at each end, being curved toward the poles since the most beginning anaphase. 6) The following hypothesis is presented as an essay to explain the origin of microchromosomes: Since microchromosomes parallel sex chromosomes in most respects, as for instances in heteropycnosis and pairing modus, it seems highly probable that they originate from sex chromosomes. One may suppose that the ancestral form of a given species had a sex chromosome which used to lose a small centric fragment when it divided during meiosis. This fragment might well be at first an unstable one. Later, to compensate the effects of such a deficiency a mechanism arose through evolution which produced two useful results : a) the establishment of the fragment as a permanent structure of the cell nucleus and b) the acquirement by the sex chromosome of the faculty of passing to one pole without losing any of its ends.

Ecological sustainability and urban form

One controversial idea present in the debate on urban sustainability is that urban sprawl is an ecological stressing problem. We have tested this popular assumption by measuring the ecological footprint of commuting and housing of the 163 municipalities of the Barcelona Metropolitan Region and by relating the estimated values with residential density and accessibility, the fundamental determinant of residential density according to the Monocentric City Model.
