The aim of the study was to determine the correlations between intracellular calcium ion level and a cell's ability to survive. The intracellular concentration of Ca 2+ ions, maintained through different mechanisms, plays an important role in signalling in cells. The deregulation of these mechanisms by various cell stressors (e.g. cytotoxic agents) can disturb Ca 2+ homeostasis and influence Ca 2+ -dependent signalling pathways in the cell. Perturbations of intracellular electrochemical equilibrium may lead to changes in cell function or even to cell death. According to some experimental results, one of the cell stressors may be exposure to magnetic fields (MF). Because of the wide distribution of MF sources in our environment, magnetic fields have recently been intensively examined in relation to the occurrence of cancer. Nevertheless, two questions still remain unanswered: Is the influence of MF on cells positive or negative, and what mechanism(s) underlie the effects of MF action on cells? Most studies focus on the influence of MF on Ca 2+ ion fluxes as calcium ions play the role of intracellular second messengers, triggering many signalling cascades. Physical models assuming the mechanisms generating the disturbance of ionic transport and/or the dysfunction of ion–protein complexes in cells due to MF action have been widely discussed in the literature, but a detailed explanation of experimental results is still awaited. The dynamics of the concentration of intracellular calcium ions can be detected by various methods, including optical and non-optical techniques. This review combines an insight into basic intracellular Ca 2+ regulative mechanisms and common techniques used to detect changes in Ca 2+ concentration inside the cell. The emphasis here is on the determination of Ca 2+ regulative mechanisms developed in non-excitable cells (e.g. U937 cells, HeLa, etc.), which are probably mainly involved in cell responses to external stress (e.g. MF stimuli).

Delirium is an acute-onset syndrome that exacerbates patients' condition and significantly increases consequential morbidity and mortality. There is no comprehensive, cellular and tissue-level, pathophysiological theory. The melatonin hormone imbalance has been shown to be linked to circadian rhythms, sleep–wake cycle disturbances, and delirium incidence. There has been relatively little research about melatonin in delirium, and there has been no such study done in the group of elderly patients of a general medicine ward yet. The aim of our study was to compare melatonin hormone concentration in relation to the presence of delirium in elderly patients hospitalized in the general medicine ward. Blood samples were collected four times a day for two days (at 12:00, 18:00, 00:00 and 6:00), on the day when delirium was diagnosed and 72 h after the delirium resolution. Delirium was diagnosed with the Confusion Assessment Method and the criteria of the Diagnostic and Statistic Manual of Mental Disorders, 4th Revision. The mean age of 30 patients (73.3% women) was 86.5 ± 5.2 years. Delirium was diagnosed most often on the second and third day of hospitalization. A lot of predisposing and precipitating factors for delirium were identified. There was a significant difference in the melatonin hormone concentration measurement at 12:00 when patients had acute delirium and after its resolution [18.5 (13.8, 27.5) vs 12.9 (9.8, 17.8), p < 0.01]. Different patterns of the melatonin hormone concentration were shown in analyses in the subgroups defined according to the patients' diagnosis of dementia. We found that the delirium recovery was, in fact, associated with the alteration of the daily profile of melatonin. [ABSTRACT FROM AUTHOR]

The growing incidence of dementia in ageing societies is a major concern of health care organizations. Because of its detrimental influence on the mental and functional statuses of elderly people, it leads to increased economic burdens caused by the social and financial needs of patients with dementia and their caregivers. There has been no data concerning the prevalence of dementia in the elderly in the general Polish community so far. The main aim of the study was to assess the prevalence of cognitive impairment suspected of dementia among the Polish elderly and the relationships between cognitive performance and age, gender, place of residence and educational status. The presented data was the result of nationwide, multicentre PolSenior Study conducted from 2007 to 2011 in the Polish elderly population. Cognitive functions were evaluated using Mini-Mental State Examination (MMSE) performed by pre-trained nurses. The result of MMSE lower than 24 points was classified as cognitive impairment suspected of dementia and divided according to its severity into three stages: mild, moderate and severe dementia. The results were analysed in two ways: raw MMSE and MMSE scores after Mungas adjustment (MMSEadj), that is, corrected for age and educational level, and these were compared. To verify the suspicion of dementia an assessment was complemented by an interview of carers for the occurrence and course of memory disorders, treatment of dementia and by functional status assessment. In order to assess the prevalence of suspicion of dementia in the general Polish population, statistical analyses based on weighting were done. The suspicion of dementia on the basis of raw MMSE was made in 20.4% of respondents aged 65 years and more, and after Mungas adjustment in 12.1% of older subjects. The prevalence of cognitive impairment grew with increasing age, as well as depending on the educational status of elderly respondents in both types of analyses; raw MMSE and MMSEadj. There was no significant difference in the prevalence of cognitive impairment according to gender in the general population (raw MMSE); however in analyses including MMSEadj results, the suspicion of dementia was made more often among men. Suspicion of dementia based on raw MMSE and MMSEadj results was made significantly more often among men than women at the age of 65–69 years, and significantly more often among the oldest women, aged 90 years and more. Suspicion of dementia was diagnosed more often in respondents living in rural communities (based on raw MMSE, but not on MMSEadj), which might be related to the differences in their educational status.

Frailty and cardiovascular disease share some of the pathophysiologic features. Our objective was to review and metaanalyse the available published evidence on the topic. We performed a comprehensive literature search for studies where pulse wave velocity (PWV) or carotid-ankle vascular index (CAVI) has been linked with frailty in older persons. Of the initial 362 abstracts, after the application of the PRISMA approach, 5 were analysed in detail. We calculated within-study and pooled standardised mean differences of aortic stiffness measures between frail and non-frail (0.62 [0.31–0.92], p < 0.0001, I2 = 88%), and pre-frail and non-frail (0.32 [0.14–0.51], p = 0.0006, I2 = 72%) groups. In two studies it was possible to extract directly or calculate based on published data the odds ratios for the concomitant frailty, associated in one case with CAVI greater by 1 m/s and in another with cfPWV >13 m/s, indicating greater probability of concomitant frailty given greater aortic stiffness. Across the studies, the prevalence of hypertension, diabetes mellitus, hyperlipidaemia, and smoking tended to increase from non-frail, to pre-frail, and frail groups, presenting a possibility of important confounding, but also a common pathophysiology. In conclusion, the pooled analysis of the published cross-sectional study results indicates a relation between aortic stiffness and frailty in older subjects. However, well designed prospective studies are needed to answer the questions of causality. • There is a relationship between cardiovascular risk factors and frailty. • The published studies are cross sectional. • In our metaanalysis, CAVI or cfPWV increase from non-frail to frail persons • Hypertension, diabetes, hyperlipidaemia or smoking may be important confounders.

Background Blood pressure (BP) control in the elderly is often limited by poor compliance with prescribed regimen. Both can be influenced by clinical cognitive or mood impairments; however, the impact of subclinical alterations of cognition or mood remains unknown. Objectives To assess the relation between cognition, mood, and BP control in treated older hypertensive patients. Design Cross-sectional association study. Setting Predefined substudy to the POLFOKUS nationwide survey investigating the correlates of poor BP control in patients randomly drawn from primary and specialist practices across Poland. Participants 1988 outpatients ≥65 years of age treated for hypertension for at least 1 year. Measurements BP was mean of at least 2 office measurements. We assessed adherence to antihypertensive medications using a questionnaire and performed screening tests for cognitive deficits [Abbreviated Mental Test Score (AMTS)] and mood disorders [Geriatric Depression Scale (GDS)]. In all patients, we used a unified (BP <140/90 mm Hg) and in ≥80 years old a unified or age-specific (<150 mm Hg systolic BP) definition of BP control. We fitted logistic regression models to assess the probability of poor BP control in association with cognitive and mood disturbances. Results The mean [standard deviation (SD)] age of 1988 (65.6% women) patients was 73.9 (6.0) years (19.3% ≥80 years old). Cognitive and mood impairments were observed in 8.0% and 37.2%, respectively. Mean systolic and diastolic BP were 141.8 (16.4) and 83.6 (9.5) mm Hg, respectively. According to age-stratified and unified definition of proper BP control, goal BP was achieved in 65.4% and 38.5% patients ≥80 years of age, respectively. In younger patients, the control reached 46%. Globally, 66% patients adhered to antihypertensive medications. Poor compliance was related to cognitive and mood impairments. When unified goal was applied, there was a 15.0% higher risk of finding poor BP control per 1 score lost in AMTS and an 8.0% increase per 1 score gained in GDS (all P < .001). Conclusion Poorer BP control is related to subclinical worsening of cognition and mood, which supports widespread use of the Comprehensive Geriatric Assessment even in apparently self-dependent older patients with hypertension.

Abstract: Falls are a geriatric syndrome which affects the physical and psychological well-being of the aged. So far, in Poland there have not been any population-based data on the prevalence of falls among the elderly. The aim of this analysis was to assess the prevalence of falls, their circumstances and consequences in the Polish population aged 65years and older in comparison to younger respondents aged 55–59years, and the relation of falls to visual and hearing deficits. Mean age of the 4920 elderly subjects (51.6% men) was 79.4±8.7years. Falls in the past year were reported by 10.4% of the younger and 19.1% of the older subjects. In both groups falls occurred more frequently in women (11.9% vs. 8.7%, p=0.03 in the younger and 22.7% vs. 13.2%, p<0.001 in the older group). In the group of older subjects falls occurred most often during walking (66.7% vs. 50.7% in the group of 55–59years old), p=0.005), while the younger more often fell while practicing sports (5.48% vs. 0.8% in the group 65+, p<0.001) and risky activities (respectively: 13.7% vs. 4.9%, p=0.002). A similar percentage of younger and older fallers reported one (44.0% and 46.1% respectively) or more falls (56.1% and 53.9%; p=0.6). The percentage of recurrent fallers grew with increasing age (Cc=0.177; p<0.001). The prevalence of injurious falls was similar in the younger and older groups (45.4% and 42.8%, p=0.53). In both genders fall-related injuries were more frequent in younger elderly (65–74years old) and in subjects 90years old and older. In the non-standardized analysis and after adjustment for age and gender visual and hearing impairments and its degree were associated with falls but both relations lost statistical significance after adjustment for a set of explanatory variables. Despite somewhat lower estimates, falls in older Poles are no less an important factor influencing overall health than in other populations. The higher prevalence of multiple falls should draw attention of the health-care policy makers. Sensory impairment may add to the risk of falls and should be adequately taken care of, however the priority in the future fall prevention initiative should be given to stronger factors, such as age, type of activity, overall health, cognitive function and functional status.

FRAGILITY (Psychology) , *NURSING care facilities , *QUALITY of life , *METHODOLOGY - Abstract
Frailty is a common geriatric syndrome that indicates homeostenosis and increased risk of disability and mortality. It is amenable to intervention when detected. Hence, screening frailty is of utmost importance to preserve quality-of-life and function in older age. Simpler Modified Fried Frailty Scale is a very practical frailty screening tool that has recently been introduced and has rooted from the original Fried Scale. It is developed in Turkish and has been shown to predict mortality in nursing home residents. Considering the variety of languages in Europe, it seems valid to adapt and validate this tool in different European languages. Thereby, it is expected that clinicians will have the possibility to screen for frailty more quickly and easily in their practice across many countries. This report is written to explain the details of the final consensus methodology suggested for Simpler Modified Fried Frailty Scale validation in order to guide and help the research teams in their studies. • Frailty is a common geriatric syndrome that increases disability and mortality. • Screening frailty is of utmost importance to preserve quality-of-life and function. • Simpler Modified Fried Frailty Scale is a very practical and rapid screening tool. • Simpler Modified Fried Frailty Scale predicted mortality in nursing home residents. • Simpler Modified Fried Frailty Scale validation will guide the research teams.
