The "Artwork Effect" paradigm: A model for planning and assessing cognitive stimulation for people with dementia through museum visits.

This paper proposes a paradigm ("Artwork Effect" paradigm) to study the impact of museum stimulation programs for people with dementia. The literature concerning viewing and making art is considered. The paradigm, comprising qualitative and quantitative measures, is illustrated. The implementation of a shared paradigm of assessment can contribute to the validation of an assessment model to evaluate museum stimulation programs for people with dementia: a low-cost nonpharmacological intervention useful for the stimulation of cognitive functions and for increasing the well-being of people with dementia and their caregivers.

The Savvy Caregiver Program: A Probe Multicenter Randomized Controlled Pilot Trial in Caregivers of Patients Affected by Alzheimer's Disease.

Alzheimer's disease (AD) is a major cause of disability in the elderly, leading to a considerable burden on caregivers and high costs to society. Psycho-education programs such as the Savvy Caregiver Program (SCP) are reported to be a successful means of reducing caregivers' distress through various intervention strategies. The aim of the present study was to assess the efficacy of the SCP in reducing the burden and psychological symptoms in caregivers of AD patients and to analyze the coping strategies adopted by the caregivers. The study was designed as a multicenter, randomized, controlled, pilot clinical trial. One hundred and sixty-four caregivers of patients with probable AD were randomized. The SCP was structured in six, weekly, two-hour sessions. All the clinical scales were administered before treatment, two weeks and six months after treatment. Caregivers in the SCP group displayed better coping strategies adopted to positive attitudes, and they tended to be less anxious and less depressed than those in the control group. However, caregiver burden levels were not reduced in SCP caregivers. The patients of SCP caregivers received a lower number of new prescriptions of neuroleptics during the 6 months of follow-up than the patients of control caregivers and apathy was the neuropsychiatric symptom that improved most as a result of the SCP. The results of this study suggest that the SCP may improve coping strategies of caregivers of people affected by AD, influencing their psychological symptoms and those of their patients.

Nutritional assessment of residents in long-term care facilities (LTCFs): recommendations of the task force on nutrition and ageing of the IAGG European region and the IANA.

Unintentional weight loss and Undernutrition are major problems among older people living in Long-Term Care Facilities (LTCF). Undernutrition manifests in LTCF particularly as weight loss and low Body Mass Index (BMI) and is associated with increased morbidity and mortality as well as with functional decline. There are many factors associated with poor nutritional status and affecting protein-energy intake and/or energy expenditure. These include age of 85 years or older, low nutrient intake, loss of ability to eat independently, swallowing and chewing difficulties, becoming bed-ridden, pressure ulcers, history of hip fracture, dementia, depressive symptoms and suffering from two or more chronic illnesses. Nutritional evaluation is an essential part of the Comprehensive Geriatric Assessment (CGA). This evaluation ranges from methods such as BMI to several validated tools such as Mini-Nutritional Assessment (MNA). After diagnosis, the management of undernutrition in LTCF requires a multidisciplinary approach which may involve dietary and environmental improvements and managing multiple co-morbidities, while avoiding polypharmacy as far as possible. Finally, the need for supplementation or artificial (tube) feeding may be considered taking into account the CGA and individual needs. This document presents a succinct review and recommendations of evaluation and treatment of undernutrition.

Reality orientation therapy combined with cholinesterase inhibitors in Alzheimer's disease: randomised controlled trial.

BACKGROUND: Reality orientation therapy combined with cholinesterase inhibitors has not been evaluated in patients with Alzheimer's disease. AIMS: To perform such an evaluation. METHOD: We randomly assigned 79 of 156 patients treated with donepezil to receive a reality orientation programme. Caregivers of the treatment group were trained to offer the programme at home 3 days a week, 30 min/day, for 25 consecutive weeks, and were invited to stimulate and involve patients in reality-based communication. RESULTS: The treatment group showed a slight improvement in Mini-Mental State Examination (MMSE) scores (mean change +0.2, s.e.=0.4) compared with a decline in the control group (mean change -1.1, s.e.=0.4; P=0.02). Similarly for the Alzheimer's Disease Assessment Scale--Cognition (treatment group mean change +0.4, s.e.=0.8; control group -2.5, s.e.=0.8; P=0.01). The intervention had an equal effect on cognition in those with mild (MMSE score > or = 20) and moderate (score <20) dementia. No significant effect was observed for behavioural and functional outcomes. CONCLUSIONS: Reality orientation enhances the effects of donepezil on cognition in Alzheimer's disease.

Pharmacological profile of 9,11-dehydrocortexolone 17alpha-butyrate (CB-03-04), a new androgen antagonist with antigonadotropic activity.

A series of new cortexolone-related derivatives has been synthesized and investigated for potential anti-androgenic activity. Among the steroids evaluated, 9,11-dehydrocortexolone 17alpha-butyrate (CB-03-04) was the most promising one. The compound displayed a strong local antiandrogenic activity in hamster's flank organ test, and it was also found to be effective in the rat after subcutaneous injection. When compared to other well known androgen antagonists, the rank order of topical anti-androgenic activity in that test was: cyproterone acetate (CAS 427-51-0) > or = CB-03-04 > finasteride (CAS 98319-26-7) > flutamide (CAS 13311-84-7). In addition, the steroid had selective antigonadotropic activity, when injected into parabiotic rats, and was about as active as progesterone. The activity of CB-03-04 was ascribed mainly to its ability to compete with the stimulating effects of testosterone and dihydrotestosterone and, concurrently, to inhibit the gonadotropins hypersecretion. This bimodal mechanism of action could be predictive for the clinical usefulness of the steroid in the treatment of prostate cancer and benign prostate hypertrophy.

The Caregiver Burden Inventory in evaluating the burden of caregivers of elderly demented patients: results from a multicenter study.

BACKGROUND AND AIMS: The burden perceived by caregivers of patients with dementia is a fundamental prognostic aspect in the history of the disease. The aim of this study was to demonstrate the internal consistency of the Caregiver Burden Inventory (CBI), a scale used to quantify burdens in different aspects of a caregiver's life, and the influence of patients' and caregivers' characteristics on its different dimensions. METHODS: In this cross-sectional study, 419 demented patients and their caregivers were evaluated in 16 geriatric centers in Italy. Cognitive status and behavioral disturbances were assessed by the Mini Mental State Examination (MMSE) and Neuropsychiatric Inventory (NPI), respectively. Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) were also evaluated. Comorbidity was assessed by the Cumulative Illness Rating Scale (CIRS). The severity of dementia was evaluated by the Clinical Dementia Rating (CDR) score. Caregiver distress due to the behavioral problems of the patient was assessed by the Neuropsychiatric Inventory-Distress, a subscale of the NPI which evaluates stress caused by each behavioral disturbance of the patient, and by the Brief Symptom Inventory which evaluates anxiety and depression. Burden was evaluated by the CBI. RESULTS: The CBI showed very high internal consistency (Cronbach's alpha value > 0.80). Factor analysis showed that the items clustered into four dimensions, and not five as originally proposed. Multiple regression analysis revealed that patients' behavioral disturbances and disability were the major predictors of the time-dependent burden; the psychophysical burden was explained mainly by caregiver anxiety and depression. CONCLUSIONS: The CBI proved to be an effective multidimensional tool for evaluating the impact of burden on many aspects of caregivers' lives.

Biological profile of cortexolone 17alpha-propionate (CB-03-01), a new topical and peripherally selective androgen antagonist.

The aim of this study was to investigate the antiandrogenic activity of a new monoester of cortexolone, cortexolone 17alpha-propionate (CAS 19608-29-8, CB-03-01). Although the compound displayed a strong local antiandrogenic activity in hamster's flank organ test, it did not exhibit antiandrogenic activity in rats after subcutaneous injection, nor did it affect gonadotropins hypersecretion when injected to parabiotic rats. As topical antiandrogen, the steroid resulted about 4 times more active than progesterone (CAS 57-83-0) and, when compared to known antiandrogen standards, it was about 3 times more potent than flutamide (CAS 13311-84-7), about 2 times more effective than finasteride (CAS 98319-26-7) and approximately as active as cyproterone acetate (CAS 427-51-0). Its pharmacological activity seemed to be primarily related to its ability to antagonistically compete at androgen receptor level; nevertheless its primary pharmacological target needs to be further investigated. Its topical activity, along with the apparent absence of systemic effects, anticipates this compound to have the potential of representing a novel and safe therapeutic approach for androgen-dependent skin disorders.
