INTRODUCTION Current guidelines suggest using cystatin-C to confirm a reduced creatinine-based estimated glomerular filtration rate (eGFRcr) when the latter is thought to be inaccurate. Older adults have reduced muscle mass, which may affect the accuracy of eGFRcr. We evaluated the use of cystatin-C-based eGFR (eGFRcys) to confirm reduced eGFRcr among adults ≥ 80 years of age and, for compariso...

statement of the problem assessment of tooth caries rate, especially in high-risk portion of the society, is important in order to plan appropriate preventive protocols purpose the aim of the present study was to determine dental caries prevalence in 13‒19-year-old iranian students using two different caries indicators, including dmft and sic index. materials and methods a total of 398 students...

BACKGROUND One of the primary reasons for hospitalisation among elderly individuals with heart failure (HF) is poor self-care. Self-awareness of having HF may be a key-element in successful self-care. The prevalence of self-awareness of HF, and how it is affected by age-and HF-related factors, remains poorly understood. The aims of the present study were to determine the prevalence of self-awar...

The objective of this study was to explore HIV testing experiences and service views of Canadian Aboriginal youth in order to provide information for HIV testing services. An exploratory, mixed-method, community-based research design was used for this study. Findings reported here are from 210 survey participants who had experienced an HIV test. Youth were recruited through 11 Aboriginal organi...

BACKGROUND Prevalence of atrial fibrillation (AF) is increasing, due partly to the ageing population. The Birmingham Atrial Fibrillation Treatment of the Aged (BAFTA) Trial, published in 2007, provided strong evidence of the effectiveness of warfarin at age≥80 years, but the impact on incidence of AF-related stroke and peripheral embolic vascular events is uncertain. METHODS We studied age-sp...

BACKGROUND In dementia screening, most studies have focused on early cognitive impairment by comparing patients suffering from mild dementia or mild cognitive impairment with normal subjects. Few studies have focused on modifications over time of the cognitive function in the healthy elderly. The objective of the present study was to analyze the cognitive function changes of two different sampl...

The complexity of the rearing environment is important for behavioral development and fearfulness. The aim of this study was to test the hypothesis that laying hens reared in a complex aviary system with exposure to mild intermittent stressors would be less fearful, less sensitive to stress, and would use elevated areas of the pen more often as adults than hens reared in a barren cage environme...
