The presence and functional significance of white matter lesions in the ageing brain and in dementia as well as their relation to blood pressure are often discussed. The aim of this study was to evaluate cerebral blood flow in white matter (WMCBF) and its relation to systemic blood pressure and multichannel EEG. WMCBF was measured in 24 elderly women with senile dementia of Alzheimer's type (SDAT,

To clarify whether orthostatic blood pressure is affected by the type of diabetes, cardiac autonomic neuropathy, and the duration of diabetes, orthostatic blood pressure (passive 90°tilt) was evaluated in 102 patients with insulin dependent diabetes mellitus (IDDM), 51 patients with non-insulin dependent diabetes mellitus (NIDDM), and in 238 control subjects in a first study followed up after 8 to

We consider the problem of feasible coordination control for multiple homogeneous or heterogeneous mobile vehicles subject to various constraints (nonholonomic motion constraints, holonomic coordination constraints, equality/inequality constraints etc). We develop a general framework involving differential-algebraic equations and viability theory to describe and determine coordination feasibility

A biological bank has been developed to extend the biochemical and molecular research base for a prospective study on diet and cancer in the city of Malmo, Sweden. The study entered individuals 45-69 years of age, of which 30,382 individuals (45%) participated. Each individual entering the bank has stored samples of viable mononuclear leukocytes (MNLs; -140°C) and granulocytes (GRANs; -80°C) or bu

Background: Prevalence of peptic ulcer disease has been associated to diet. Some dietary factors seem to have bactericidal effect which may modify the risk of peptic ulcer disease. The objective was to analyze associations between dietary habits and peptic ulcers. Design: A cross sectional population study. Subjects: One thousand, one hundred and thirty-five subjects out of 11,700 randomly invited

The ecosystem services (EcoS) concept is being used increasingly to attach values to natural systems and the multiple benefits they provide to human societies. Ecosystem processes or functions only become EcoS if they are shown to have social and/or economic value. This should assure an explicit connection between the natural and social sciences, but EcoS approaches have been criticized for retain

Controlled invariant set and viability regulation of dynamical control systems have played important roles in many control and coordination applications. In this paper we develop a \textit{temporal} viability regulation theory for general dynamical control systems, and in particular for control affine systems. The time-varying viable set is parameterized by time-varying constraint functions, with

The aim of the study was to determine dietary risk factors for fracture in men aged 46-68 years. Six thousand five hundred and seventy-six men were randomly invited using the Municipal Registry to a diet and health study. The diet was assessed using a combined 7-day menu book for hot meals, beverages and dietary supplements and a quantitative food frequency questionnaire for other foods. The fract

Background. If several risk factors for disease are considered in a regression model and these factors are affected by measurement errors, the observed relative risk will be attenuated. In nutritional epidemiology, several nutrient variables show strong correlation, described as collinearity. The observed relative risk will then depend not only on the validity of the chosen diet assessment method

Background The involvement of patient preferences is sometimes forgotten in the evidence-based medicine and the development of clinical guidelines. Many preunderstandings among clinical staff exist on patients’ preferences towards smoking and alcohol cessation programs. The aim of this project was therefore to get insight of the patients’ preferences regarding undertaking smoking and risky alcohol

The main objectives were to study relationships between the design of group living (GL) units and psychiatric symptoms in demented patients before, 6 months after, and 1 year after admission to GL units. The study population comprised 105 demented elderly (83 ± 6 years), 37% with dementia of Alzheimer's type and 58% with vascular dementia. The patients were relocated by the municipal care planning

The nutrient intake in geriatric long-stay patients and the mortality risk associated with low energy intake were studied in 61 patients, 43 women and 18 men, with a mean age of 87 years, at a geriatric long-stay care hospital during a 6-month follow-up. Dietary intake was assessed with a 9-day dietary record. Energy expenditure was calculated assuming a physical activity level of 1.33 × basal met

Aims and objectivesThe aim was to explore and describe the child's active participation in daily healthcare practice at children's hospital units in Sweden.Objectives(a) Identify everyday situations in medical and nursing care that illustrate children's active participation in decision‐making, (b) identify various ways of active participation, actual and optimal in situations involving decision‐ma

Quantified electroencephalographic activity (EEG) has been used to study normal ageing and dementia. Few studies have described longitudinal changes in the very old. A cognitive decline has been described in subjects with white-matter lesions and hypertension but the association with hypotension is unclear. Our aim was to study the predictive value of quantified EEG for the development of cognitiv

The importance of some personality characteristics for improvement of activities of daily life (ADL) was studied in sixty-six stroke patients, initially admitted to geriatric rehabilitation (n = 37) or the department of medicine (n = 29), 3 years after stroke. Outcome measurements were activities of daily life and motor and mental functions assessed using the Activity Index (AI) by Hamrin and Wohl

Objective: To assess burden of caregivers to stroke patients three year after a primary stroke and to test validity and reliability of a novel caregiver burden scale (CB scale). Design: A longitudinal community-based 3- year follow-up study of 35 consecutive primary stroke patients initially admitted to an Acute Medical Unit (mean age 82yr). The validity of the CB scale was studied in 150 patients

Objective: To describe dietary habits and use of mineral supplements in relation to nutrient recommendations and anaemia. Design: a population-based cohort study. Subjects: 2665 men and 3878 women, born between 1926 and 1945, randomly invited and participating in the prospective 'Malmo Diet and Cancer study' during 1991-1992. Methods: The diet was assessed using a combined 7-day menu book for hot

In this paper we propose a new ratio control architecture that exploits the use of inversion-based feedforward actions to achieve a fast set-point step response while keeping the required ratio between two process variables. The recently developed ratio tracking station is then achieved to increase the robustness of the system. A user design parameter allows the selection of the trade-off between
