BackgroundAlthough intensive blood pressure reduction has cardiovascular benefits, the absolute benefit is greater in those at higher cardiovascular disease (CVD) risk.ObjectivesThis study examined whether N-terminal pro–B-type natriuretic peptide (NT-proBNP) helps identify subjects at higher risk for CVD events across systolic blood pressure (SBP), diastolic blood pressure (DBP), or pulse pressure (PP) categories.MethodsParticipants from the ARIC (Atherosclerosis Risk In Communities) study visit 4 (1996 to 98) were grouped according to SBP, DBP, or PP categories and further stratified by NT-proBNP categories. Cox regression models were used to estimate hazard ratios for incident CVD (coronary heart disease, ischemic stroke, or heart failure hospitalization) and mortality across combined NT-proBNP and/or BP categories, adjusting for CVD risk factors.ResultsThere were 9,309 participants (age: 62.6 ± 5.6 years; 58.3% women) with 2,416 CVD events over a median follow-up of 16.7 years. Within each SBP, DBP, or PP category, a higher category of NT-proBNP (100 to <300 or 300 pg/ml, compared with NT-proBNP <100 pg/ml) was associated with a graded increased risk for CVD events and mortality. Participants with SBP 130 to 139 mm Hg but NT-proBNP ≥300 pg/ml had a hazards ratio of 3.4 for CVD (95% confidence interval: 2.44 to 4.77) compared with a NT-proBNP of <100 pg/ml and SBP of 140 to 149 mm Hg.ConclusionsElevated NT-proBNP is independently associated with CVD and mortality across SBP, DBP, and PP categories and helps identify subjects at the highest risk. Participants with stage 1 hypertension but elevated NT-proBNP had greater cardiovascular risk compared with those with stage 2 SBP but lower NT-proBNP. Future studies are needed to evaluate use of biomarker-based strategies for CVD risk assessment to assist with initiation or intensification of BP treatment. 相似文献

BACKGROUND: Apathy is a common symptom in patients with dementia and has adverse consequences for patients and caregivers. Most treatments for apathy, particularly non-pharmacologic interventions, have not been evaluated in controlled trials. OBJECTIVES: This study evaluated the efficacy of a kit-based activity intervention, compared to a time and attention control (one-on-one meetings with an activity therapist) in reducing apathy and improving quality of life in 37 patients with dementia. METHODS: The design was a randomized, controlled, partially masked clinical trial. All outcome measures were administered at baseline and follow-up. The primary outcome measure was the apathy score of the Neuropsychiatric Inventory (NPI). Other outcome measures were the NPI total score, the Alzheimer Disease Related Quality of Life scale(ADQRL), and the Copper Ridge Activity Index (CRAI). RESULTS: There was a significant reduction in NPI apathy scores in both treatment groups. The only significant difference between the two treatment groups was a modest advantage for the control intervention on the CRAI cueing subscale (p = 0.027), but not on the other CRAI subscales. There was also a greater within group improvement in quality of life ratings in the control intervention (p=0.03). CONCLUSIONS: Despite the substantial improvement in apathy scores during the course of the study, there was no clear advantage to the reminiscence-based intervention over the time and attention, one-on-one control intervention. More research is needed to develop specific behavioral interventions for apathy in patients with dementia. 相似文献

Introduction
Apathy is common in neurocognitive disorders (NCDs) such as Alzheimer's disease and mild cognitive impairment. Although the definition of apathy is inconsistent in the literature, apathy is primarily defined as a loss of motivation and decreased interest in daily activities.Methods
The Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment (ISTAART) Neuropsychiatric Syndromes Professional Interest Area (NPS-PIA) Apathy workgroup reviewed the latest research regarding apathy in NCDs.Results
Progress has recently been made in three areas relevant to apathy: (1) phenomenology, including the use of diagnostic criteria and novel instruments for measurement, (2) neurobiology, including neuroimaging, neuropathological and biomarker correlates, and (3) interventions, including pharmacologic, nonpharmacologic, and noninvasive neuromodulatory approaches.Discussion
Recent progress confirms that apathy has a significant impact on those with major NCD and those with mild NCDs. As such, it is an important target for research and intervention. 相似文献7.

Cerebrovascular disease (CVD) is an important cause of psychiatric disability in the elderly. Much of this disability can be attributed to dementia and lesser degrees of cognitive impairment, which result from strokes and other forms of cerebrovascular pathology. While vascular dementia is common, estimates of its frequency vary due to its clinical and pathologic heterogeneity, the challenges involved in its measurement and its frequent co-occurrence with Alzheimer's disease. Nevertheless the clinical features and natural histories of vascular dementia can be described, and risk factors have been identified and include hypertension, diabetes mellitus, hyperlipidaemia, other conditions that promote atherosclerosis, and rare genetic mutations. While vascular dementia is not curable, treatments are available. For example, a few recent clinical trials suggest that cholinesterase inhibitors have some efficacy. Our knowledge of the risk factors has also provided opportunities for the primary and secondary prevention of vascular dementia, and indicates promising avenues for research. 相似文献

OBJECTIVES: To compare the demographic, clinical, and psychiatric characteristics of residents living in small (< or = 15 beds) and large assisted living (AL) facilities in the United States. METHODS: One hundred and ninety-eight residents in 10 large and 12 small assisted living facilities were comprehensively assessed as part of the Maryland Assisted Living Study (MD-AL). The presence or absence of dementia and psychiatric disturbances and the facilities' recognition and management of these disorders were compared across the two types of AL. Aspects of care delivery were also compared. RESULTS: Small facilities had a higher prevalence of dementia (81%) compared to larger facilities (63%) and the mean Mini-Mental State Examination (MMSE) across all residents in small facilities (mean 13.04) was than in large facilities (mean 19.93)(p = 0.000). Almost all (98%) of the residents of small homes carried a diagnosis of a dementia or other psychiatric diagnosis, compared to 74% of residents in large facilities (p < 0.001). Psychosis in particular was more prevalent in the smaller homes and the mean Neuropsychiatric Inventory score, a measure of neuropsychiatric symptoms, was higher compared to large homes. Falls were more common in larger homes despite a greater number of personal care hours per week. The use of safety devices and restraints was significantly less common in large facilities compared to smaller homes, where 'geri-chair' and bedrails were more often used. CONCLUSIONS: Rates of dementia and psychiatric disorder differ in assisted living facilities depending on size of facility. 相似文献
