BackgroundChronic heart failure is a very common condition in the elderly, characterized not only by high mortality rates, but also by a strong impact on health-related quality of life (HRQOL). Previous studies of HRQOL in elderly heart failure subjects have included mostly outpatients, and little is known about determinants of HRQOL in hospitalized elderly population, especially in Serbia. In this study, we tried to identify factors that influence HRQOL in elderly patients hospitalized with chronic heart failure in Serbia.MethodsThe study population consisted of 136 patients aged 65 years or older hospitalized for chronic heart failure. HRQOL was assessed using the Minnesota Living with Heart Failure questionnaire. Predictors of HRQOL were identified by multiple linear regression analysis.ResultsUnivariate analysis showed that patients with lower income, a longer history of chronic heart failure, and longer length of hospital stay, as well as those receiving aldosterone antagonists and digoxin, taking multiple medications, in a higher NYHA class, and showing signs of depression and cognitive impairment had significantly worse HRQOL. Presence of depressive symptoms (P<0.001), higher NYHA class (P=0.021), lower income (P=0.029), and longer duration of heart failure (P=0.049) were independent predictors of poor HRQOL.ConclusionDepressive symptoms, higher NYHA class, lower income, and longer duration of chronic heart failure are independent predictors of poor HRQOL in elderly patients hospitalized with chronic heart failure in Serbia. Further, there is an association between multiple medication usage and poor HRQOL, as well as a negative impact of cognitive impairment on HRQOL. Hence, measures should be implemented to identify such patients, especially those with depressive symptoms, and appropriate interventions undertaken in order to improve their HRQOL.

Ageism is stereotyping and prejudice against individuals or groups because of their age. Robert Butler first used it in 1969, to express a systematic stereotyping and discrimination against elderly people. Available data appears to confirm that attitudes of children to the old age differ from that of adults. The study population consisted of 162 subjects (56 school children, 48 nurses and 58 elderly patients). Each subject in the survey was asked to respond to the following three questions: Question #1: “Is the old age unattractive ?”; Question #2: “How old is an old man? Question #3: “What should you do to have a long life (what is good for longevity)? The majority of polled children (33) gave positive statements about ageing in their responses to the first item, while most of the nurses gave condition answers, like: “It is not unattractive if you are healthy”. Elderly subjects made up a group with the majority of negative responses (in percentage), as only 33% of them answered that old age is not unattractive. All three groups of subjects demonstrated a good knowledge of what is considered good for longevity, and had a generally positive health attitude. Our results indicate that majority of children have positive perception and attitude about old age, which leads us to conclusion that ageism is adopted later in life.

Background: Ample evidence has proven that the functional property of cells decreases over the years. Nevertheless, although it has taken decades to convince ourselves that elderly people belong to a specific age group both biologically and medicinally, and in whom special criteria have to be taken into consideration, it seems that even they themselves do not present an homogenous group. Objective: Today we often hear of authors of studies speaking of two subpopulation groups – one group that ages by all the laws of aging that we have encountered and accepted thus far, and the other group that seems to postpone aging due to ‘programmed death’, or more specifically due to low mastery/low emotional support or because of additional reasons; however, the existence of the two groups seems eminent. Methods: The identification of these two groups would allow us to find more realistic results in studies, and therefore a more efficient therapy for certain diseases. Results: This hypothesis does not contradict the theories of aging that we have accepted (at least not the majority) and also does not contradict the fact that there is a large interindividual variability. This hypothesis doubts and claims there are exceptions to the initial assumption of geriatrists and gerontologists that ‘parallel to the aging process, the functions of all organs and organ systems lessen.’ Conclusion: The identification of these two groups would allow us to find more realistic results in studies, and therefore more efficient therapy for certain diseases.

Purpose: Previous research has shown that poor health-related quality of life (HRQOL) is associated with adverse long-term prognosis in patients with heart failure (HF); however, there have been inconsistencies among studies and not all of them confirmed the prognostic value of HRQOL. In addition, few studies involved elderly patients and most focused on all-cause mortality and HF-related hospitalization as outcomes. The aim of our study was to determine whether HRQOL is a predictor and an independent predictor of long-term cardiac mortality, all-cause mortality, and HF-related rehospitalization in elderly patients hospitalized with HF. Patients and methods: This prospective observational study included 200 elderly patients hospitalized with HF in Serbia. HRQOL was measured using the Minnesota Living with Heart Failure questionnaire (MLHFQ). The median follow-up period was 28 months. The primary outcome was cardiac mortality, and all-cause mortality and HF-related rehospitalization were secondary outcomes. Survival analysis was conducted using the Kaplan–Meier method and Cox-proportional hazards regression. Results: Subjects with poor HRQOL (higher than the median MLHFQ score) had a higher probability of cardiac mortality ( P =0.029) and HF-related rehospitalization ( P =0.001) during long-term follow-up. Poor HRQOL was an independent predictor of cardiac mortality (HR: 2.051, 95% CI: 1.260–3.339, P =0.004), all-cause mortality (HR: 1.620, 95% CI: 1.076–2.438, P =0.021), and HF-related rehospitalization (HR: 2.040, 95% CI: 1.290–3.227, P =0.002). Conclusion: HRQOL is an independent predictor of long-term cardiac mortality in elderly patients hospitalized with HF. It also independently predicts all-cause mortality and HF-related rehospitalization. HRQOL could be used as a complementary clinical predictive tool in this patient population.

The aim of this study was to determine the basis for anti-tumor immune reactivity observed in patients with human epidermal growth factor receptor-2 (HER-2) (3+) breast carcinoma using an in vitro model in which the role of the HER-2-specific monoclonal antibody Herceptin was also investigated. Patients with metastatic breast cancer who had their primary tumor resected were included in this study. Peripheral blood mononuclear cell (PBMC)-dependent cytotoxicity in the presence or absence of Herceptin were assessed using the survival of target breast adenocarcinoma MDA-MB-361 cells as a parameter in a (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) test. We observed a significant increase in PBMC-dependent cytotoxicity when autologous serum was introduced in the assay. Furthermore, the addition of Herceptin significantly increases their cytotoxicity. These data suggest that autologous serum constitutively contains factors that might affect PBMC-dependent cytotoxic activity against HER-2 positive cancer cells.
