- Degeneration of cholinergic neurons in the basal forebrain correlates with cognitive decline in patients with Alzheimer's disease (AD). Targeted delivery of exogenous nerve growth factor (NGF) has emerged as a potential AD therapy due to its regenerative effects on the basal forebrain cholinergic neurons in AD animal models. Here we report the results of a first-in-man study of encapsulated cell (EC) biodelivery of NGF to the basal forebrain of AD patients with the primary objective to explore safety and tolerability.

- OBJECTIVE: The effects of (-)-phenserine (phenserine) and placebo/donepezil treatment on regional cerebral metabolic rate for glucose (rCMRglc) and brain amyloid load were investigated by positron emission tomography in 20 patients with mild Alzheimer's disease in relation to cerebrospinal fluid (CSF) and plasma biomarkers, and cognitive function. METHODS: The first 3 months of the study was a randomized, double-blind, placebo-controlled phase, during which 10 patients received phenserine (30 mg/day) and 10 patients the placebo. Three to 6 months was an open-label extension phase, during which the placebo group received donepezil (5 mg/day) and the phenserine group remained on phenserine. After 6 months, all patients received phenserine treatment up to 12 months. The patients underwent positron emission tomography examinations to measure rCMRglc (8F-FDG) and amyloid load (11C-PIB) at baseline and after 3 and 6 months of the treatment. Neuropsychological and biomarker data were collected at the three times of positron emission tomography imaging. RESULTS: Statistically significant effects on a composite neuropsychological test score were observed in the phenserine-treated group compared with the placebo and donepezil group at 3 and 6 months, respectively. Values of rCMRglc were significantly increased in several cortical regions after 3 months of phenserine treatment, compared with baseline, and correlated positively with cognitive function and CSF beta-amyloid 40 (Abeta40). Cortical Pittsburgh Compound B retention correlated negatively with CSF Abeta40 levels and the ratio Abeta/beta-secretase-cleaved amyloid precursor protein. In CSF, Abeta40 correlated positively with the attention domain of cognition. INTERPRETATION: Phenserine treatment was associated with an improvement in cognition and an increase in rCMRglc.

- BACKGROUND Patients' involvement in their healthcare has been associated with improved treatment outcomes in chronic illness. Less is known about the affects of patient involvement on the outcomes of acute illness, such as myocardial infarction. A better understanding of patients' views and behaviour during hospitalization might improve clinical practice and enhance patient involvement. AIM The aim of this study was to develop and evaluate a questionnaire for measuring patients' perceptions of their involvement during hospitalization for myocardial infarction care. METHODS Focus groups with myocardial infarction patients provided the basis for the construction of the questionnaire. Questionnaire validity and reliability were evaluated in a small pilot study and a larger cross-sectional study among myocardial infarction patients at eleven Swedish hospitals. RESULTS The questionnaire demonstrated good validity and reliability, with six factors measuring patient views and behaviour regarding involvement. CONCLUSION The questionnaire appears to be a useful tool for evaluating the perceptions and behaviour of patients regarding patient involvement in myocardial infarction care. Use of this questionnaire may provide insight regarding areas of patient-staff interaction that need improvement. Pinpointing such areas may lead to improved patient involvement, satisfaction with care, and treatment outcomes.

- Objective To investigate whether patient involvement during hospitalization for acute myocardial infarction (MI) was associated with health and behavioural outcomes 6–10 weeks after hospital discharge. Background Patient involvement has been associated with improved health outcomes in chronic disease, but less research has focused on the effects of patient involvement in acute conditions, such as MI. Design Self-administered questionnaire study. Questionnaire results were run against medical outcome data in a national database of cardiac patients. Setting and participants Cardiac patients (n = 591) on their first follow-up visit after hospitalization for MI at 11 Swedish hospitals. Main outcome measures Patient ratings of three questionnaire scales related to involvement; cardiovascular symptoms, medication compliance, participation in cardiac rehabilitation, and achievement of secondary preventive goals. Results More positive patient ratings of involvement were significantly associated with fewer cardiovascular symptoms 6–10 weeks after hospital discharge. In contrast, patients who attended cardiac rehabilitation and achieved the goals for smoking cessation and systolic blood pressure were significantly less satisfied with their involvement. No association was found between involvement ratings and medication compliance. Conclusion This study represents a first attempt to examine associations between patient involvement in the acute phase of illness and short-term health outcomes. Some significant associations between involvement and health and behavioural outcomes after acute MI were found. However, higher involvement ratings were not consistently associated with more desirable outcomes, and involvement during hospitalization was not associated with MI patient health and behaviour 6–10 weeks after hospital discharge to the extent hypothesized.

- Background: Patients' involvement in their healthcare has been associated with better health outcomes. However, few studies have examined whether patient involvement affects the work of healthcare professionals. A better understanding of professionals' views and behaviour is necessary for improving clinical practice and optimizing patient involvement. Aim: To measure perceptions and behaviour regarding patient involvement among physicians and nursing staff caring for patients with acute myocardial infarction. Methods: A questionnaire study conducted in 2005 among cardiology staff at twelve Swedish hospitals. The questionnaire included six scales measuring staff views and behaviour. Results: Physicians, registered nurses, and practical nurses did not differ significantly in their views of patient involvement, but did differ significantly in behaviour (p<.001). All three groups felt that an actively involved patient enriched their work, at the same time increasing their work load and taking time from other tasks. Physicians discussed daily activities and lifestyle changes with myocardial infarction patients before hospital discharge to a greater extent than nursing staff (p<.001). Conclusion: Physicians and registered nurses viewed time constraints as a hinder for patient involvement, while practical nurses felt unsure in communicating with patients. Considering these organizational and professional issues may improve patient involvement and health outcomes in myocardial infarction care. (C) 2007 European Society of Cardiology.

- BACKGROUND Healthcare legislation in several nations now dictates the responsibility of health care professionals to involve patients in decisions concerning care and treatment. However, few studies have examined the impact of patient involvement on the work of health care professionals. A better understanding of staff views and behaviour might enhance patient involvement. AIM The aim of this study was to develop and validate a questionnaire for measuring views and behaviour regarding patient involvement among physicians and nursing staff caring for patients with myocardial infarction. METHODS Focus groups among cardiology staff provided the basis for the construction of the questionnaire. Questionnaire validity and reliability were evaluated in a small pilot study and a larger cross-sectional study among cardiology staff at twelve Swedish hospitals. RESULTS The questionnaire demonstrated good validity and reliability, with two factors measuring staff views and four measuring behaviour. CONCLUSION The questionnaire appears to be a useful tool for evaluating the perceptions and behaviour of physicians and nursing staff regarding patient involvement in myocardial infarction care. Use of this questionnaire may provide insight regarding areas of staff-patient interaction that need improvement, as well as implications of patient involvement for the work of each professional group on cardiology wards.

- Transgenic animals expressing mutant human amyloid precursor protein (APP) are used as models for Alzheimer disease (AD). Ideally, behavioral tests improve the predictive validity of studies on animals by mirroring the functional impact of AD-like neuropathology. Learning and memory studies in APP transgenic models have been difficult to replicate. Standardization of procedures, automatization or improved protocol design can improve reproducibility. Here the IntelliCage, an automated system, was used for behavioral testing of APP female transgenic mice with both the Arctic and Swedish mutations, the tg-ArcSwe model. Protocols covering exploration, operant learning, place learning and extinction of place preference as well as passive avoidance tests were used for longitudinal characterization of behavior. Differences in exploratory activity were significant at four months of age, when plaque-free tg-ArcSwe mice visited less frequently the IntelliCage corners and initially performed fewer visits with licks compared to non-tg animals, inside the new environment. Fourteen months old tg-ArcSwe mice required a longer time to re-habituate to the IntelliCages than non-tg mice. At both ages tg-ArcSwe mice perseverated in place preference extinction test. Fourteen months old tg-ArcSwe mice were impaired in hippocampus-dependent spatial passive avoidance learning. This deficit was found to inversely correlate to calbindin-D28k immunoreactivity in the polymorphic layer of the dentate gyrus. Reduced water intake and body weight were observed in 4 months old tg-ArcSwe animals. The body weight difference increased with age. Thus behavioral and metabolic changes in the tg-ArcSwe APP model were detected using the IntelliCage, a system which provides the opportunity for standardized automated longitudinal behavioral phenotyping.
