Prognostic factors of long-term survival in geriatric inpatients. Should we change the recommendations for the oldest people?

ObjectivesIdentification of optimal predictors of the 5.5-year survival in former geriatric inpatients.Investigation of the direction and shape of the relationship between mortality risk and its predictors.DesignRetrospective survival analysis with the application of the Cox proportional hazards model.SettingTeaching geriatric unit.Participants478 inpatients (mean age 77.9; +6.8) discharged from geriatric ward during year 2008, without any exclusion criteria.MeasurementsComprehensive geriatric assessment of numerous health variables, body mass index (BMI), clinical and biochemical findings, and outcomes of the final diagnosis. Records on the dates of deaths were obtained from the Provincial Office of Population Register.ResultsDuring the 5.5-year follow-up 209 (43.7%) patients died. In the multivariate setup, six risk factors with an independent impact on mortality were identified: age (p=0.036), cognitive functioning on the Blessed test (p=0.005), score on instrumental ADL (p<0.0001), score on Charlson comorbidity index (p<0.0001), cholesterol level (p<0.0001), BMI (p<0.0001), and hemoglobin level (p=0.02). The latter two predictors exhibited a significant inverted J-shaped association with mortality, i.e., considerably higher risk of death corresponds to the lower values of these variables in comparison to their higher levels.ConclusionOlder age, worse IADL and cognitive functioning, and higher comorbidity were recognized as endangering one’s long-term survival. On the other hand, moderate obesity (BMI 36), higher cholesterol and the absence of anemia (hemoglobin 13.6 g/dL) are associated with longer survival. Therefore, irrespective of the individualized treatment and physical exercise, nutrient-dense food seems to be a key recommendation to prevent frailty or malnutrition in the oldest and comorbid population.

Kynurenine and its metabolites in Alzheimer's disease patients

PURPOSE The kynurenine pathway (KP) is a major route of tryptophan metabolism. Several metabolites of this pathway are proposed to be involved in the pathogenesis of Alzheimers disease. The aim of this study was to evaluate peripheral KP in patients with Alzheimer type dementia and a detailed analysis of correlation between kynurenine (KYN), kynurenic acid (KYNA), 3-hydroxykynurenine (3-HK), anthranilic acid (AA), quinolinic acid (QUIN) and degree of neuropsychological changes in AD. MATERIAL/METHODS The plasma concentration of tryptophan and its products degradation by kynurenine pathway were analyzed in 34 patients suffering from Alzheimer type dementia and 18 controls in similar age using high-performance liquid chromatography technique. RESULTS In demented patients we found lower tryptophan and KYNA concentrations. There was a non-significant increase of KYN, 3-HK and AA levels, and a Marked increase of QUIN in Alzheimers disease group. We observed positive correlations between cognitive function tests and plasma KYNA levels, and inversely correlations between these tests and QUIN levels in Alzheimer type dementia. CONCLUSIONS Increased TRP degradation and simultaneous altered kynurenines levels were found in plasma of AD patients. It proves activation of peripheral kynurenine pathway in this type of dementia. The alterations of two main KYN metabolites: KYNA and QUIN seem to be associated with the impairment of the cognitive function in AD patients. This appears to offer Novel therapeutic opportunities, with the development of new compounds as a promising perspective for brain neuroprotection.

Disabled older people's use of health and social care services and their unmet care needs in six European countries

BACKGROUND The national health and social care systems in Europe remain poorly integrated with regard to the care needs of older persons. The present study examined the range of health and social care services used by older people and their unmet care needs, across six European countries. METHODS Family carers of older people were recruited in six countries via a standard protocol. Those providing care for disabled older people (n = 2629) provided data on the older persons service use over a 6-month period, and their current unmet care needs. An inventory of 21 services common to all six countries was developed. Analyses considered the relationship between older peoples service use and unmet care needs across countries. RESULTS Older people in Greece, Italy and Poland used mostly health-oriented services, used fewer services overall and also demonstrated a higher level of unmet care needs when compared with the other countries. Older people in the United Kingdom, Germany and Sweden used a more balanced profile of socio-medical services. A negative relationship was found between the number of different services used and the number of different areas of unmet care needs across countries. CONCLUSIONS Unmet care needs in older people are particularly high in European countries where social service use is low, and where there is a lack of balance in the use of health and social care services. An expansion of social care services in these countries might be the most effective strategy for reducing unmet needs in disabled older people.

Components of the difficulties, satisfactions and management strategies of carers of older people: A principal component analysis of CADI-CASI-CAMI

Objectives: To perform a psychometric evaluation of the Carers Assessment of Difficulties Index, Carers Assessment of Satisfactions Index and the Carers Assessment of Managing Index (CADI-CASI-CAMI). Method: Data was collected in three European countries from informal carers of older people (n = 295) via a common protocol. Carers completed: (a) a questionnaire containing items on demographics and caregiving characteristics and (b) the CADI-CASI-CAMI indices. Principal component analysis of the CADI-CASI-CAMI indices was followed by internal consistency analysis of emergent components. Scales derived by summing items loading on the components were analysed for their association with the demographic and caregiving characteristic variables. Results: CADI produced six internally consistent and interpretable components, CASI five and CAMI seven. Subscales derived from the components were significantly associated with the demographic and caregiving characteristic variables, providing initial support for construct validity. Conclusion: The CADI-CASI-CAMI indices are recommended as an assessment tool for in-depth work with family carers of older people and as a research tool for large-scale studies of family care.

Syncope and near-syncope as a multifactorial problem in geriatric inpatients: Systemic hypotension is an underrated predictor for syncope exclusively.

PURPOSE Syncope (SC) and near-syncope (NS) are still misunderstood syndromes. Aim of study was to determine the risk factors for SC, NS, as well as for both entities (SC/NS) in geriatric inpatients reporting these events within the last year, irrespectively of the reason of admission to hospital. MATERIAL AND METHODS The retrospective study covered 250 patients, consecutively admitted to the geriatric ward. Patients were assigned to the three models: SC and/or NS in total, n=106; isolated NS, n=72; SC with co-existing NS, if any, n=34, and compared with patients without any such events (n=144). The patients underwent a comprehensive geriatric assessment and complete clinical investigation. The binary logistic regression was applied to predict risk factors for each of the models. RESULTS Falls were most predictive for NS model (OR 35.4; 95% CI 10.3-121.1), and systemic hypotension for SC model (OR 92.9; 95% CI 6.1-1421.0). The highest specificity (85%) and sensitivity (81%) were found for the SC/NS model, with the highest contribution by falls (OR 18.1; 95% CI, 7.6-45.2), orthostatic hypotension (OR 8.1; 95% CI, 3.5-18.5), a history of stroke or transient ischemic attack, treatment with an angiotensin receptor blocker, plasma creatinine >1.4mg/dL, negatively self-rated health, vertigo, pathology of carotid arteries, and lack of hypertension. CONCLUSIONS Syncope and near-syncope in geriatric inpatients have multifactorial and cumulative aetiology, with blurred, frequently overlapping boundaries between them. The falls, postural hypotension, and/or brain hypoperfusion of different origin seem to be most predictive of the both events, however low systemic blood pressure was predictive for the syncope exclusively.

For better or worse : Factors predicting outcomes of family care of older people over a one-year period. A six-country European study

Objectives Demographic change has led to an increase of older people in need of long-term care in nearly all European countries. Informal carers primarily provide the care and support needed by dependent people. The supply and willingness of individuals to act as carers are critical to sustain informal care resources as part of the home health care provision. This paper describes a longitudinal study of informal care in six European countries and reports analyses that determine those factors predicting the outcomes of family care over a one-year period. Methods Analyses are based on data from the EUROFAMCARE project, a longitudinal survey study of family carers of older people with baseline data collection in 2004 and follow-up data collection a year later in six European countries (Germany, Greece, Italy, Poland, Sweden, and the United Kingdom), N = 3,348. Descriptive statistics of the sample characteristics are reported. Binary logistic random-intercept regressions were computed, predicting the outcome of change of the care dyad’s status at follow-up. Results Where care is provided by a more distant family member or by a friend or neighbour, the care-recipient is significantly more likely to be cared for by someone else (OR 1.62) or to be in residential care (OR 3.37) after one year. The same holds true if the care-recipient has memory problems with a dementia diagnosis (OR 1.79/OR 1.84). Higher dependency (OR 1.22) and behavioural problems (OR 1.76) in the care-recipient also lead to a change of care dyad status. Country of residence explained a relatively small amount of variance (8%) in whether a care-recipient was cared for by someone else after one year, but explained a substantial amount of variance (52%) in whether a care-recipient was in residential care. Particularly in Sweden, care-recipients are much more likely to be cared for by another family or professional carer or to be in residential care, whereas in Greece the status of the care dyad is much less likely to change. Discussion The majority of family carers continued to provide care to their respective older relatives over a one-year period, despite often high levels of functional, cognitive and behavioural problems in the care-recipient. Those family carers could benefit most from appropriate support. The carer/care-recipient relationship plays an important role in whether or not a family care dyad remains intact over a one-year period. The support of health and social care services should be particularly targeted toward those care dyads where there is no partner or spouse acting as carer, or no extended family network that might absorb the caring role when required. Distant relatives, friends or acquaintances who are acting as carers might need substantial intervention if their caregiving role is to be maintained.

Silent strain of caregiving: exploring the best predictors of distress in family carers of geriatric patients

Objectives The aim of this article was to identify the best predictors of distress suffered by family carers (FCs) of geriatric patients. Methods A cross-sectional study of 100 FC-geriatric patient dyads was conducted. The negative impact of care (NIoC) subscale of the COPE index was dichotomized to identify lower stress (score of ≤15 on the scale) and higher stress (score of ≥16 on the scale) exerted on FCs by the process of providing care. The set of explanatory variables comprised a wide range of sociodemographic and care-related attributes, including patient-related results from comprehensive geriatric assessments and disease profiles. The best combination of explanatory variables that provided the highest predictive power for distress among FCs in the multiple logistic regression (LR) model was determined according to statistical information criteria. The statistical robustness of the observed relationships and the discriminative power of the model were verified with the cross-validation method. Results The mean age of FCs was 57.2 (±10.6) years, whereas that of geriatric patients was 81.7 (±6.4) years. Despite the broad initial set of potential explanatory variables, only five predictors were jointly selected for the best statistical model. A higher level of distress was independently predicted by lower self-evaluation of health; worse self-appraisal of coping well as a caregiver; lower sense of general support; more hours of care per week; and the motor retardation of the cared-for person measured with the speed of the Timed Up and Go (TUG) test. Conclusion Worse performance on the TUG test was only the patient-related predictor of distress among the variables examined as contributors to the higher NIoC. Enhancing the mobility of geriatric patients through suitably tailored kinesitherapeutic methods during their hospital stay may mitigate the burden endured by FCs.

Cognitive Functioning of Geriatric Patients: Is Hypovitaminosis D the Next Marker of Cognitive Dysfunction and Dementia?

The study objective is to investigate whether vitamin D is associated with the cognitive function of geriatric patients. This cross-sectional study involved 357 patients hospitalized in the geriatric ward who complained of memory problems (mean age: 82.3 years). The level of cognitive function was measured with the Mini-Mental State Examination (MMSE) and the clinical diagnosis of dementia was established according to the International Classification of Diseases (ICD-10) criteria. The serum 25-hydroxy vitamin D was measured with liquid chromatography-tandem mass spectrometry. The iterative Bayesian model averaging (BMA) procedure was applied to linear and logistic regression models in order to identify the best set of factors describing cognitive dysfunction and dementia, respectively. According to BMA, there is strong evidence that higher vitamin D levels, higher body mass index (BMI), and higher mobility function measured with the Timed Up and Go (TUG) test are independently associated with better cognitive performance and lower risk of dementia. Additionally, there is strong evidence that fewer years of education and lower vitamin B12 plasma levels independently describe worse cognitive performance. However, vitamin B12 levels higher than 800 pg/mL is negatively associated with the MMSE performance. Hypovitaminosis D in geriatric patients is an underrated marker of cognitive dysfunction and dementia.

The willingness of informal carers of older people to continue caring : results of the EUROFAMCARE study

OBJECTIVES : To determine the prospective impact of Iso-Strain at Work (Iso-W) and Iso-Strain at Home (Iso-H) in workers, on long term absenteeism. METHODS : In the Belstress III study (N= 2675 workers from 7 enterprises) Job-Demand-Control-Social Support (KARASEK ) as well as Stress problems at Home (KLITZMAN) and Social Support outside work (SYME & BERKMAN) –calculated accordingly in Iso-Strain at Home - were measured besides classical socio-demographic data (age, sex, educational level, professional status, type of enterprise, language ). Absenteeism was registred independently by the enterprise during 1-year of follow-up. Fourteen days of absence and more was considerd as longterm absence (N=320). RESULTS : Multiple logistic regressions of long term absences revealed that Iso-W was statistically significant (OR :1.54 {1.12-2.13}) when not controlled for socio-demographic variables, whereas after control it losts its statistical significance. Iso-H without controlling for possible counfounders was significant (OR : 1.67{1.21-2.32}) and remained significant after control for socio-demographic variables. When both Iso-Strain dimensions were included in the same analysis and controlled for the other variables, only Iso-H was significant with an OR of 1.69 {1.22-2.35} CONCLUSIONS : When considering the deleterious influence of work Strain on health without benefiting from the social support from boss or colleagues, one should take into account additionally its equivalent outside work (ISO-Strain at Home).
