Observational Study
The prognostic value of the plasma N-terminal pro-brain natriuretic peptide level on all-cause death and major cardiovascular events in a community-based population.
Despite growing evidence that N-terminal pro-brain natriuretic peptide (NT-proBNP) has an important prognostic value for patients with cardiovascular disease, chronic kidney disease, etc, the prognostic significance of NT-proBNP levels in the general population has not been established. The aim of this study was to evaluate the clinical significance of NT-proBNP in a community population. ⋯ The plasma NT-proBNP level is a strong and independent prognosis factor for all-cause death and MACEs in the community population. The NT-proBNP cut-point for the prognostic value remains to be further studied. NT-proBNP is a strong and independent prognostic factor for all-cause death and MACEs in individuals older than 65 years and MACEs in individuals younger than 65 years.

Management of geriatric patients would be simplified if a universally accepted definition of frailty for clinical use was defined. Among definitions of frailty, Fried frailty phenotype criteria constitute a common reference frame for many geriatric studies. However, this reference frame has been tested primarily in elderly patients presenting with relatively good health status. ⋯ Fried frailty phenotype criteria seem useful for geriatric inpatient assessment, despite diagnostic limitations. High prevalence of frailty among geriatric inpatients suggests that evaluation for frailty should be considered a part of the comprehensive geriatric assessment.

The current study was designed to perform deep analyses of the associations of biomarkers, including high-sensitivity C-reactive protein (hs-CRP), N-terminal prohormone of brain natriuretic peptide (NT-proBNP), and homocysteine (Hcy), with insulin resistance (IR), metabolic syndrome (MetS), and diabetes risk and evaluate the abilities of biomarkers to identify IR, MetS, and diabetes risk in Chinese community-dwelling middle-aged and elderly residents. ⋯ Serum HDL-c levels were the major determinant of the associations between serum hs-CRP levels and MetS and the key link between inflammation and MetS. There was no other association of these biomarkers with IR, MetS, and diabetes risk after full adjustment.

Frailty has been recognized as a risk factor for geriatric adverse events. Little is known of the role of psychosocial factors associated with frailty in explaining negative outcomes of aging. This study was aimed at 1) evaluating the differences in psychosocial factors among robust, prefrail, and frail individuals and 2) investigating whether there was any interaction effect of frailty status with empirically identified clusters of psychosocial factors on autonomy in the activities of daily living (ADLs). ⋯ We performed an analysis of covariance which showed differences between robust, prefrail, and frail individuals for all the psychosocial variables: Center for Epidemiologic Studies Depression Scale, F(2, 205)=18.48, P<0.001; Friendship Scale, F(2, 205)=4.59, P=0.011; UCLA Loneliness Scale, F(2, 205)=5.87, P=0.003, controlling for age and sex. Using the same covariates, the two-way analysis of covariance indicated an interaction effect of frailty with psychosocial factors in determining ADLs, F(4, 199)=3.53, P=0.008. This study demonstrates the close relationship between frailty and psychosocial factors, suggesting the need to take into account simultaneously physical and psychosocial components of human functioning.

Many age-associated diseases are accompanied by pain. There is no doubt that pain is underrecognized among elderly nursing home residents and the diagnosing of pain is a real challenge in subjects with dementia. The aim of the study was to characterize analgesic use among nursing home residents and to delineate the putative associations between pain management and cognitive functions of elderly persons. ⋯ The rate of subjects who were not receiving any pain treatment was higher in residents with MMSE between 0 and 9 points than in those with MMSE between 24 and 30 points (P=0.0151). Furthermore, ten residents (9.1%) with severe dementia were treated with analgesics PRN. The results of our study point to a remarkably low use of analgesics in nursing home residents in Poland and indicate a need to introduce pain evaluation and monitoring of drug treatment appropriateness as a standard procedure in the geriatric assessment in nursing homes.
