Question: The purpose of the present study was to evaluate the detection rate of genomic aberrations in haematological malignancies using oligobased array-CGH (oaCGH) analysis in combination with karyotyping and fluorescence in situ hybridization (FISH) analyses, and its feasibility in a clinical pragmatic approach.', 'The 4x180K Cancer Cytochip array was applied in 96 patients with various haematological malignancies in a prospective setting and in 41 acute myeloid leukemia (AML) patients retrospectively.', 'Combined use of oaCGH analysis and karyotyping improved the overall detection rate in comparison to karyotyping-alone and vice versa. In cases with normal karyotypes oaCGH analysis detected genomic aberrations in 66% (39/60) of cases. In the group of simple karyotypes oaCGH analysis extended karyotypic findings in 39% (12/31) while oaCGH analysis extended the karyotypic findings in 89% (39/44) of cases with complex karyotypes. In 7% (5/75) of cases oaCGH analysis failed in detecting the observed abnormalities by karyotyping.

Answer: Does oligo-based High-resolution aCGH Analysis enhance Routine Cytogenetic Diagnostics in Haematological Malignancies?


Question: The EuroSCORE (European System for cardiac operative risk evaluation) stratifies cardiac risk surgery in easy and accessible manner; it was validated in North America with good results but in many countries of Latin America is used routinely without prior validation. Our objective was to validate the EuroSCORE in patients with cardiac valve surgery at the Instituto Nacional de Cardiología Ignacio Chávez (INCICh) in México.', 'EuroSCORE additive and logistic models were used to predict mortality in adults undergoing cardiac valve surgery from march 2004 to march 2008. The goodness of fit test of Hosmer-Lemeshow was used to evaluate the calibration. The area under the ROC curve was calculated to determinate discrimination.', 'We included 1188 patients with ages of 51.3±14.5 years, 52% women. There were significant differences in the prevalence of risk factors among the INCICh and the EuroSCORE populations. Total mortality was 9.68% versus 5% and 5.6% predicted by additive and logistic EuroSCORE. According to additive EuroSCORE the risk was low in 11.3%, intermediate in 52.9% and high in 35.9%; for these groups the mortality was .7%, 6.34% and 17.4% against those predicted of 2%, 3.9% and 7.64%. Hosmer-Lemeshow test had a P<.001 for both models and the area under the ROC curve was .707 and .694 for additive and logistic EuroSCORE.

Answer: Do [ EuroSCORE underestimate the mortality risk in cardiac valve surgery of Mexican population ]?


Question: Disability in older African American adults is common, but its basis is unclear. We tested the hypothesis that the level of motor function is associated with incident disability in older African Americans after adjusting for cognition.', 'A prospective observational cohort study of 605 older community-dwelling African American adults without dementia was carried out. Baseline global motor score summarized 11 motor performances, cognition was based on 19 cognitive tests, and self-reported disability was obtained annually. We examined the association of motor function with incident disability (instrumental activities of daily living [IADL], activities of daily living [ADL], and mobility disability) with a series of Cox proportional hazards models which controlled for age, sex, and education.', 'Average follow-up was about 5 years. In proportional hazards models, a 1-SD increase in baseline level of global motor score was associated with about a 50% decrease in the risk of subsequent IADL, ADL, and mobility disability (all p values < .001). These associations were unchanged in analyses controlling for cognition and other covariates. Further, the association of global motor score and incident ADL disability varied with the level of cognition (estimate -5.541, SE 1.634, p < .001), such that higher motor function was more protective at higher levels of cognition. Mobility and dexterity components of global motor score were more strongly associated with incident disability than strength (all p values < .001).

Answer:
Does motor Function be Associated With Incident Disability in Older African Americans?
