Calcium ion transients in neutrophils from patients with sporadic Alzheimer's disease.

Abnormalities involving intracellular calcium homeostasis have been detected in Alzheimer's disease brain and fibroblasts as well as presenilin-1 mutation-bearing cells. In the present study we investigated inositol(1,4,5)trisphosphate-mediated calcium transients as well as calcium responses via mechanisms not related to surface receptors in Alzheimer's disease polymorphonuclear (PMN) granulocytes, using the tripeptide formyl-methionyl-leucyl-phenyl alanine (fMLP) and calcium ionophore ionomycin, respectively. fMLP elicited a biphasic response with an initial, fast increase in intracellular free calcium concentrations followed by a second, lower phase with no significant differences in either maximal response or time course between Alzheimer's disease granulocytes and controls.

Inhibition of [3H]forskolin binding by Gpp[NH]p may reflect adenylyl cyclase coupling to Gi.

The effect of the GTP-analogue guanylyl 5'-imidodiphosphate (Gpp[NH]p) on [3H]forskolin binding was studied in rat brain using autoradiography. In the striatum, 100 microM Gpp[NH]p produced a 40% increase in binding, whereas a decrease of about 30% was observed with low Gpp[NH]p concentrations (0.1-1 microM).

Differences between and within genders in caregiving strain: a comparison between caregivers of demented and non-caregivers of non-demented elderly people.

Fifty-two caregivers for demented and 66 non-caregivers for non-demented elderly were investigated both within a gender and between genders. All participants were relatives and a burden questionnaire was used. The results showed that there was not always a difference between the caregivers for demented and the non-caregivers for non-demented elderly which may indicate that being a relative, even to a non-demented elderly, has obviously its own problems and importance.

Quality of life and traumatic spinal cord injury.

Objective: To determine associations between major outcome variables after traumatic spinal cord injury (SCI) and quality of life (QL).

Subjects: Of a total population of 353 SCI patients, 320 participated, 261 men and 59 women living in the greater Stockholm area: 124 were tetraplegic, 176 were paraplegic, and 20 had no classified level. Mean age was 42 years (range, 17 to 78).

Postnatal depression: a hidden illness.

The main objectives of this study were (i) to find out to what extent postnatal depression (PND) in mothers was recognized at Well Baby Clinics (WBCs) in Stockholm, (ii) to study the prevalence of PND using the Edinburgh Postnatal Depression Scale (EPDS), (iii) to test the positive predictive value of the EPDS against an interview-based Research Diagnostic Criteria (RDC) diagnosis of depression and (iv) to identify sociodemographic risk factors for PND. Case-records of 1128 infants were reviewed at WBCs to obtain a baseline rate of PND. Two per cent of the mothers were identified in the routine service of the WBCs as being depressed during the first 3 months postpartum.

NMDA and AMPA receptors evoke transmitter release from noradrenergic axon terminals in the rat spinal cord.

N-methyl-D-aspartate (NMDA) stimulated release of [3H]noradrenaline (NA) from prelabelled rat spinal cord slices. The release was partially insensitive to tetrodotoxin (TTX) and was inhibited by the NMDA antagonist MK-801. Alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionate (AMPA) also evoked release of [3H]NA, which was enhanced by blocking AMPA receptor desensitization with cyclothiazide.

Psychoendocrine concomitants in patients following a new design of a geriatric day-care unit.

Background: Seventeen nondemented geriatric day-care attendees were subjected to a reorganized rehabilitation programme. It is suggested that increased control of and participation in the rehabilitation process might decrease psychoendocrine stress from uncertainty and passivity.

Method: The new programme was a change from a traditional one-shift day-care into a two-shift design with two different patient sets a day.

Suppressed neuropeptide Y (NPY) mRNA in rat amygdala following restraint stress.

We have previously demonstrated that NPY produces anxiolytic-like effects through actions in the amygdala, and that anxiogenic-like effects of restraint stress are mediated through this structure. Here, we examined the effects of restraint stress on NPY mRNA levels in amygdala and several other brain regions. A sensitive solution hybridization-RNase protection assay (RPA) was developed, employing a combination of internal and external standards, which allowed absolute quantitation of NPY mRNA in tissue-samples of less than 10 mg.

The opinions of district nurses regarding the knowledge, management and documentation of patients with chronic pain.

This is the first of two studies investigating district nurses' opinions regarding the knowledge, management and nursing documentation of patients with chronic pain conditions, before and after the introduction of 'pain advisers' in one health care region in Stockholm. Seventy (97%) district nurses at 12 selected primary health care centres (PHCCs) answered a questionnaire. The study showed that 85% of the district nurses met patients with chronic pain conditions at least once a week.

Excessive drinking--brief intervention by a primary health care nurse. A randomized controlled trial.

Objective: To evaluate the effect of a nurse-conducted intervention on excessive drinkers.

Design: Randomized, controlled trial.

Setting: Vårby Health Centre, Stockholm.

Rehabilitation in the home versus the hospital: the importance of context.

Purpose: Stroke rehabilitation has received increased attention in the past decade. Recent trials with new alternatives such as home-based rehabilitation services are being conducted. The purpose of the study was to explore differences between a therapy session with a stroke patient in two different contexts, i.

Quantitative study of neurofilament-positive fiber length in rat spinal cord lesions using isotropic virtual planes.

Spontaneous reocurrence of neurofilament (NF)-positive fibers has been described after spinal cord lesions in rats. However, previously introduced methods to evaluate the lesion and the regenerative fiber outgrowth suffer from several biases, why a new concept of quantitative, morphological analysis after spinal cord injury is needed. Length quantification of the putatively spontaneously regenerating fibers has been difficult until recently, when two length estimators based on sampling with isotropic virtual planes within thick physical sections were introduced.

Longitudinal changes in quantitative EEG during long-term tacrine treatment of patients with Alzheimer's disease.

Quantitative EEG is a potentially useful tool in demonstrating the effects of treatments with acetylcholinesterase (AChE) inhibitors on the progression of Alzheimer's disease (AD). In order to define the profile of EEG changes during tacrine long-term treatment, for 12 months we followed 15 AD patients receiving an optimal individually tolerable dose. After 3 months theta global field power (GFP) was significantly reduced, and after 6 months both theta and delta GFP decreased.

Word production: dissociation of two retrieval modes of semantic memory across time.

To identify components that contribute to word-fluency performance, 126 patients referred to a Memory Clinic for suspected cognitive impairment underwent a neuropsychological examination including the Controlled Oral Word Association test (FAS; Benton & Hamsher, 1976). The number of words produced in the FAS test during six consecutive 10-s periods followed a negatively accelerated curve approaching an asymptotic level after about 30 s. The 18 FAS variables (3 letters x 6 periods) were entered into an exploratory factor analysis resulting in two factors.

Swedish nursing students' transition into nursing during education.

The transition from student to nurse involves the influence of several different educational aspects. The aim of this study is to elucidate the transition to the role of a nurse, which Swedish nursing students underwent during their 3 years in nursing education, as described from the perspective of their experiences with elderly patients. Interviews were conducted with the students at the end of each academic year, and the students wrote diaries about their clinical education in the second and third years.

Long-term tacrine treatment in three mild Alzheimer patients: effects on nicotinic receptors, cerebral blood flow, glucose metabolism, EEG, and cognitive abilities.

The effect of long-term treatment with tacrine (tetrahydroaminoacridine) was studied in three Alzheimer patients (aged 57, 64, and 68 years) with mild dementia. All three patients had a Mini-Mental State Examination score of 24/30 and carried at least one apolipoprotein E (ApoE) epsilon4 allele. Tacrine was given in doses between 80 and to 160 mg daily for 13-31 months.

Depressive disorders among somatizing patients in primary health care.

Unrecognized, untreated and undertreated depressive disorders incur inordinate human and economic costs, despite the availability of an exclusive array of clinical interventions. The aim of this study was to identify cases of masked depression in primary health care, employing a two-stage design. In the first stage, involving a study of 442 patients, the prevalence of recognized depression was 1.

Staff views on the Resident Assessment Instrument, RAI/MDS, in nursing homes, and the use of the Cognitive Performance Scale, CPS, in different levels of care in Stockholm, Sweden.

Multidimensional functional assessment is the basis of individualized care. It is especially important in the care of elderly, with the complexity of symptomatology and often with cognitive impairment present. An assessment instrument for elderly persons, used in this study, is the Resident Assessment Instrument/Minimum Data Set (RAI/MDS) and its incorporated MDS Cognitive Performance Scale (CPS).

Enhanced localization of amyloid beta precursor protein in the rat hippocampus following long-term adrenalectomy.

Using various antibodies to the amyloid ss precursor protein (APP) associated with Alzheimer's disease, we investigated changes in the distribution of APP in the hippocampus and neocortex of adrenalectomized (ADX) rats. In contrast to sham-operated controls, ADX rats euthanised after a survival period of 5 months showed striking APP reactivity in the CA1-CA4 fields and in the surviving cells in the dentate gyrus. Our results suggest the enhanced APP reactivity in hippocampal neurons may pertain to previous observations on the accumulation of APP fragments in the neocortex during ischemic or traumatic injury.

Parapartum mental illness: a long-term follow-Up study.

All mothers (n = 79) in the county of Stockholm who gave birth to a child during 1976-77 and were also hospitalised for the first time in a psychiatric clinic were followed up after a mean interval of 15 years. The sample was classified according to the Research Diagnostic Criteria. Comparisons were made with matched obstetric controls.

Immigration, moving house and psychiatric admissions.

This study was designed to elucidate psychiatric admission rates for native Swedes and foreign-born individuals during the period 1991-1994, when Sweden had a great influx of refugees. During the same period, and even earlier, psychiatric in-patient care had been reduced. Tests of differences between Swedes and foreign-born individuals in first psychiatric admission rates were performed using Poisson regressions, and the risk of a readmission was assessed using a proportional hazard model.

Simultaneous Ashworth measurements and electromyographic recordings in tetraplegic patients.

Objective: A recent prevalence study of 353 spinal cord injured (SCI) individuals in the greater Stockholm area showed problematic spasticity in 30% of this population. To treat spasticity, the evaluation becomes crucial. The modified Ashworth scale (MAS) is the clinically most-used scale to grade degree of spasticity.

Predictors of longitudinal changes in memory, visuospatial, and verbal functioning in very old demented adults.

Longitudinal changes in memory, visuospatial and verbal functioning in a sample of demented persons were examined. The role of several demographic, psychometric, and biological indices in predicting the rate of cognitive deterioration was also investigated. The sample consisted of 31 very old (mean age at entry = 83.

Intracerebroventricular infusion of nerve growth factor in three patients with Alzheimer's disease.

Nerve growth factor (NGF) is important for the survival and maintenance of central cholinergic neurons, a signalling system impaired in Alzheimer's disease. We have treated 3 patients with Alzheimer's disease with a total of 6.6 mg NGF administered continuously into the lateral cerebral ventricle for 3 months in the first 2 patients and a total of 0.

Preclinical symptoms of major depression in very old age: a prospective longitudinal study.

Objective: The authors' goal was to examine whether individuals diagnosed as having major depression experienced greater levels of depressive symptoms and cognitive dysfunction up to 3 years before the clinical diagnosis was rendered.

Method: The study included 185 subjects 75 years old or older who participated in a population-based longitudinal survey in Stockholm. Ten of the subjects were diagnosed as depressed up to 3 years after initial screening, and these individuals were compared with the 175 subjects who were not depressed at 3-year follow-up.
