Neoplasias uroteliais papilíferas superficiais da bexiga (pTa e pT1): correlação da expressão do p53, KI-67 E CK20 com grau histológico, recidiva e progressão tumoral

OBJETIVO: Investigar a expressão imunoistoquímica dos marcadores p53, Ki-67, CK20 em neoplasias uroteliais papilíferas superficiais da bexiga e correlacionar com o grau histológico, progressão tumoral e recidiva. MÉTODOS: Foram selecionadas amostras de 43 pacientes portadores de carcinoma de células transicionais superficiais da bexiga. Elas foram distribuídas em dois grupos, um denominado recorrente, de 18 indivíduos e outro não recorrente, com 25 casos. Foram confeccionados blocos multiamostrais. A técnica imunoistoquímica empregada foi de imunoperoxidase e os anticorpos foram: p53 (clone DO7), o Ki-67 (clone SP6) e CK20. RESULTADOS: A expressão do p53 foi observada em 11 casos, todos tumores de alto grau (p=0,0001). A progressão histológica ocorreu em seis indivíduos (p=0,0076). Dos 18 casos recorrentes, seis apresentaram imunorreação para o p53 e 12 foram negativos para este anticorpo (p=0,1715). O Ki-67 foi positivo em 17 dos 18 casos do grupo recorrente (p=0,0001) e dos 20 tumores de alto grau, 18 apresentaram reação para este anticorpo (p=0,0001). Dos 18 indivíduos que tiveram recorrência, 13 apresentaram expressão anômala para CK20 (p=0,0166). Nos carcinomas de alto grau, dos 20 casos, 16 apresentaram expressão anômala para este anticorpo, enquanto que 18 dos 23 indivíduos com tumores de baixo grau mostraram expressão habitual para a CK20 (p=0,0002). CONCLUSÃO: O p53 mostrou boa correlação com a progressão histológica e grau histológico. O Ki-67 apresentou forte associação com a recidiva e grau histológico, e a CK20 também associou-se com estas variáveis.

Reference value of brachial-ankle pulse wave velocity for the eastern Chinese population and potential influencing factors

The present study was conducted to obtain reference values for brachial-ankle pulse wave velocity (baPWV) and to evaluate influencing factors of baPWV according to gender. Using automatic devices, baPWV was measured simultaneously in 2095 subjects. A total of 647 healthy subjects, none of whom presented atherosclerotic risk factors, were analyzed in the present study. Two different statistical methods were used to obtain reference values for baPWV according to subject gender and age. The association between baPWV value and gender, as well as other features, were analyzed. For male subjects, multiple stepwise analysis showed that age, systolic blood pressure (SBP), heart rate (HR), and plasma levels of triglycerides (TG) were independent predictors of baPWV. For female subjects, age, SBP, HR, and plasma levels of uric acid (UA) were independent predictors of baPWV. In male subjects, the upper limits of baPWV values were 1497.43/1425.00, 1518.67/1513.25, 1715.97/1726.50, 1925.20/1971.90, and 2310.18/2115.00 cm/s, obtained using two different statistical methods for the age ranges of 30-39, 40-49, 50-59, 60-69, and 70 and older, respectively. For females, the upper limits of baPWV values were 1426.70/1411.13, 1559.15/1498.95, 1733.50/1739.00, 1958.63/1973.78, and 2720.80/2577.00 cm/s for the age ranges of 30-39, 40-49, 50-59, 60-69, and 70 and older, respectively. Aging is the most important influencing factor for baPWV value and its effect is more prominent in females. The reference values of baPWV according to age and gender may be useful for the clinical diagnosis and preventive therapy of cardiovascular diseases.

Association between indoxyl sulfate and bone histomorphometry in pre-dialysis chronic kidney disease patients

Introduction: Experimental studies have suggested that indoxyl sulfate (IS), a protein-bound uremic toxin, may be involved in the development of renal osteodystrophy. Objective: evaluate the association between IS levels and biochemical parameters related to mineral metabolism and bone histomorphometry in a cohort of pre-dialysis chronic kidney disease (CKD) patients. Methods: This is a post-hoc analysis of an observational study evaluating the association between coronary calcification and bone biopsy findings in 49 patients (age: 52 ± 10 years; 67% male; estimated glomerular filtration rate: 36 ± 17 ml/min). Serum levels of IS were measured. Results: Patients at CKD stages 2 and 3 presented remarkably low bone formation rate. Patients at CKD stages 4 and 5 presented significantly higher osteoid volume, osteoblast and osteoclast surface, bone fibrosis volume and bone formation rate and a lower mineralization lag time than CKD stage 2 and 3 patients. We observed a positive association between IS levels on one hand and the bone formation rate, osteoid volume, osteoblast surface and bone fibrosis volume on the other. Multivariate regression models confirmed that the associations between IS levels and osteoblast surface and bone fibrosis volume were both independent of demographic and biochemical characteristics of the study population. A similar trend was observed for the bone formation rate. Conclusion: Our findings demonstrated that IS is positively associated with bone formation rate in pre-dialysis CKD patients.

They Do Things Differently There. Essays on Cultural History

This collection of Finnish essays in cultural history will be revelatory for anglophone readers. Pioneering in the study of cultural history as early as the nineteenth century, by the 1930s Finnish scholars already deployed the broad conception of 'culture' as embracing 'everyday life' that is usually thought of as emerging in the work of Raymond Williams decades later. These essays emanate from the Department of Cultural History, established at the University of Turku in 1972, and its partner department at the University of Lapland. The collection signals new genealogies of cultural historiography in general, and in its distinctively Finnish inflections.
