BACKGROUND AD is characterized by cerebral deposition of beta-amyloid plaques with amyloid beta-peptide (Abeta) 42 as the major peptide constituent, along with neurofibrillary tangles and neuronal loss. In transgenic mice, active immunization against Abeta42 removes these plaques and improves cognitive function. A Phase I study in AD patients demonstrated(More)
Bone mineral density (BMD) was measured in 1992-93 in 129 nuclear families, including 258 parents and 183 children, and was analyzed for familial resemblance factors. BMD measurements were adjusted on weight and age. Segregation analysis rejected the monogenic hypothesis and exhibited a strong polygenic component. Variance components analysis was then used(More)
Weight loss, together with psychological and behavioural symptoms and problems of mobility, is one of the principal manifestations of Alzheimer's disease (AD). Weight loss may be associated with protein and energy malnutrition leading to severe complications (alteration of the immune system, muscular atrophy, loss of independence). Various explanations have(More)
Whether the femoral neck bone mineral density (FN BMD) of children may be better predicted from that of their parents when taking into account the anthropometry of the children was assessed in a healthy adult sample consisting of 86 mother-daughter, 32 mother-son, 32 father-daughter, and 23 father-son pairs from 128 families. Heritability for FN BMD, which(More)
OBJECTIVES To describe the characteristics of nursing home residents diagnosed with atrial fibrillation (AF) and eligible for oral anticoagulants who did not receive these drugs and to detail the conditions that physicians who decide not to prescribe anticoagulants take into account. DESIGN Cross-sectional. SETTING Nursing home. PARTICIPANTS Nursing(More)
INTRODUCTION Medication reconciliation is a process used to identify and prevent medication errors at care transition points in hospitals. The present study's main objectives were to quantify the frequency of inadvertent discrepancies (IDs) per patient and estimate the seriousness of the IDs' clinical impact. PATIENTS AND METHODS This was a prospective,(More)
CONTEXT Few large studies have been conducted to assess the relationship between circulating IGF and late-life cognition. OBJECTIVE The aim of the study was to assess the relationship between IGF-I and IGF binding protein-3 (IGFBP-3) serum levels and cognitive impairment, including Alzheimer's disease (AD). METHODS In this multicentric cross-sectional(More)
In a retrospective analysis of 13 cases of Herpes simplex encephalitis (mean age: 67.2 +/- 6.4 years; ten women, three men), the authors conclude that this infection is more often due to Herpes simplex virus 1 in the elderly. Diagnosis is difficult at an early stage, and must be suspected in case of confusion (9/13), especially feverish (11/13), associated(More)
OBJECTIVE To evaluate the relative importance of environmental and genetic factors in the determination of bone mineral density (BMD) and to quantify the risk of low BMD in healthy young adults in relation to the BMD of their parents. METHODS Dual-energy x-ray absorptiometry study of a series of 129 nuclear families (441 subjects), including 183 children(More)
Radiologists are often confronted to the choice of the most appropriate statistic tool for evaluating diagnostic imaging methods. Using a radiological literature example, the Kappa agreement test is herein described and its applications are determined. Although widely performed to determine the inter-rater agreement, this test is also suited for the(More)
