Cross-cultural differences in information disclosure evaluated through the EORTC questionnaires.

Abstract: Objective Informational needs among cancer patients are similar, but the degree of information disclosure in different cultural areas varies. In this paper, we present the results of a cross-cultural study on information received. Methods The EORTC information questionnaire, EORTC QLQ-INFO25, was administered during the treatment process. This questionnaire evaluates the information that patients report they have received. Cross-cultural differences in information have been evaluated using statistical tests such as Kruskall–Wallis and multivariate models with covariates to account for differences in clinical and demographic characteristics across areas. Results Four hundred and fifty-one patients from three cultural areas, North–Middle Europe, South Europe, and Taiwan, were included in the study. Significant differences among the three cultural areas appeared in eight QLQ-INFO25 dimensions: information about the disease; medical tests; places of care; written information; information on CD/tape/video; satisfaction; wish for more information; and information helpfulness. North–Middle Europe patients received more written information (mean = 67.2 (North) and 33.8 (South)) and South Europe patients received more information on different places of care (mean = 24.7 (North) and 35.0 (South)). Patients from North–Middle Europe and South Europe received more information than patients from Taiwan about the disease (mean = 57.9, 60.6, and 47.1, respectively) and medical tests (70.9, 70.4, and 54.5), showed more satisfaction (64.8, 70.2, and 35.0), and considered the information more helpful (71.9, 73.9, and 50.4). These results were confirmed when adjusting for age, education, and disease stage. Conclusion There are cross-cultural differences in information received. Some of these differences are based on the characteristics of each culture. Copyright © 2011 John Wiley & Sons, Ltd.

Age-Related Changes and Sex-Related Differences in Brain Iron Metabolism.

Abstract: Iron is an essential element that participates in numerous cellular processes. Any disruption of iron homeostasis leads to either iron deficiency or iron overload, which can be detrimental for humans' health, especially in elderly. Each of these changes contributes to the faster development of many neurological disorders or stimulates progression of already present diseases. Age-related cellular and molecular alterations in iron metabolism can also lead to iron dyshomeostasis and deposition. Iron deposits can contribute to the development of inflammation, abnormal protein aggregation, and degeneration in the central nervous system (CNS), leading to the progressive decline in cognitive processes, contributing to pathophysiology of stroke and dysfunctions of body metabolism. Besides, since iron plays an important role in both neuroprotection and neurodegeneration, dietary iron homeostasis should be considered with caution. Recently, there has been increased interest in sex-related differences in iron metabolism and iron homeostasis. These differences have not yet been fully elucidated. In this review we will discuss the latest discoveries in iron metabolism, age-related changes, along with the sex differences in iron content in serum and brain, within the healthy aging population and in neurological disorders such as multiple sclerosis, Parkinson's disease, Alzheimer's disease, and stroke.

Phenotype of NK Cells and Cytotoxic/Apoptotic Mediators Expression in Ectopic Pregnancy

Abstract: The expression of cytotoxic/apoptotic mediators and the phenotype characteristics of uterine NK cells (uNK) in tubal ectopic pregnancy (EP) were investigated. Samples of uterine decidua and tubal mucosa as well as peripheral blood (PB) of the same women with EP were used for phenotype characterization of NK cells and detection of cytotoxic/apoptotic mediators and IL-15. In tubal mucosa, perforin, FasL, granulysin and IL-15 were almost completely absent, but they were present in normal and EP uterine deciduas. TRAIL was present on trophoblast and tubal mucosa, contrary to its lack in normal and EP uterine decidua. CD16⁻ CD56(dim) NK cells, mostly CD94⁻ and NKG2A⁻, predominate in tubal mucosa, whereas CD16⁻ CD56(bright) NK cells, predominantly CD94(+) and NKG2A(+) prevail in EP uterine decidua. NK cells at the EP implantation site express lower percentages of perforin and granulysin, but they express a higher percentage of TRAIL than do EP uterine decidual and PB NK cells. Lower percentage of TNF-α-expressing and IL-4-expressing NK cells were found at the implantation site compared to EP uterine decidua. Authentic uNK cell population seems to be insufficient to restrict trophoblast invasion because of low expression of cytotoxic/apoptotic mediators.
