Emotional and psychological distress of persons involved in the care of patients with Alzheimer disease predicts falls and fractures in their care recipients.

BACKGROUND/AIMS: Elderly patients with dementia have a higher risk of falls and fractures as compared to cognitively intact elderly subjects. To investigate whether psychological distress of the caregiver might predispose older persons with Alzheimer disease (AD) to falls and fractures, we performed a prospective cohort study. METHODS: A consecutive series of 110 subjects with dementia underwent baseline and follow-up clinical and functional evaluations. The burden of the caregivers was recorded at baseline. Any intervening fall or fracture was ascertained at the 1-year follow-up. RESULTS: The caregiver burden was significantly higher in persons involved in the care of patients with AD who subsequently fell. In a multivariate regression model, the caregiver burden score predicted falls and fractures. CONCLUSION: Part of the increased risk of falls and fractures in AD might be due to the distress of caregivers, a factor potentially amenable to treatment.

Lung Ultrasound-Implemented Diagnosis of Acute Decompensated Heart Failure in the ED: A SIMEU Multicenter Study.

BACKGROUND: Lung ultrasonography (LUS) has emerged as a noninvasive tool for the differential diagnosis of pulmonary diseases. However, its use for the diagnosis of acute decompensated heart failure (ADHF) still raises some concerns. We tested the hypothesis that an integrated approach implementing LUS with clinical assessment would have higher diagnostic accuracy than a standard workup in differentiating ADHF from noncardiogenic dyspnea in the ED. METHODS: We conducted a multicenter, prospective cohort study in seven Italian EDs. For patients presenting with acute dyspnea, the emergency physician was asked to categorize the diagnosis as ADHF or noncardiogenic dyspnea after (1) the initial clinical assessment and (2) after performing LUS ("LUS-implemented" diagnosis). All patients also underwent chest radiography. After discharge, the cause of each patient's dyspnea was determined by independent review of the entire medical record. The diagnostic accuracy of the different approaches was then compared. RESULTS: The study enrolled 1,005 patients. The LUS-implemented approach had a significantly higher accuracy (sensitivity, 97% [95% CI, 95%-98.3%]; specificity, 97.4% [95% CI, 95.7%-98.6%]) in differentiating ADHF from noncardiac causes of acute dyspnea than the initial clinical workup (sensitivity, 85.3% [95% CI, 81.8%-88.4%]; specificity, 90% [95% CI, 87.2%-92.4%]), chest radiography alone (sensitivity, 69.5% [95% CI, 65.1%-73.7%]; specificity, 82.1% [95% CI, 78.6%-85.2%]), and natriuretic peptides (sensitivity, 85% [95% CI, 80.3%-89%]; specificity, 61.7% [95% CI, 54.6%-68.3%]; n = 486). Net reclassification index of the LUS-implemented approach compared with standard workup was 19.1%. CONCLUSIONS: The implementation of LUS with the clinical evaluation may improve accuracy of ADHF diagnosis in patients presenting to the ED.

A multi-dimensional questionnaire quantifying quality of life in elderly osteoporotic women: the Italian triple-Q osteoporosis study.

BACKGROUND AND AIMS: In advanced age, the influence of vertebral fractures on quality of life extends well beyond the usual sequelae of osteoporosis. In order to intercept older subjects' distress associated with the clinical, functional, social and psychological consequences of the disease, we developed and validated a multidimensional instrument (the triple-Q questionnaire) tailored to older women with osteoporotic fractures. We also examined specific aspects of the questionnaire correlated with bone mineral density. METHODS: 100 osteoporotic women with vertebral fractures and 100 controls aged >65 years, underwent a thorough examination, which also included X-ray of the thoraco-lumbar spine, hip densitometry, the triple-Q questionnaire, and five referral instruments evaluating function, cognition, perception of general health, mood and pain. RESULTS: The questionnaire was repeatable and able to discriminate between older women with and without vertebral fractures. There was a strong association between referral instrument scores and the corresponding single domain score of the questionnaire. Femoral BMD was also associated with scores indicating fear of falling, fear of fracture, and pain. CONCLUSIONS: The questionnaire intercepted the influence of osteoporosis on the quality of life of elderly women with vertebral fractures. Subjects who suffered from severe pain and were more fearful of falling were most likely to be severely osteoporotic.
