A population-based assessment of the impact and burden of caregiving for long-term stroke survivors.

BACKGROUND AND PURPOSE: Little attention has been focused on the demands on caregivers in stroke outcome research. A major aim of this study was to identify factors in patients associated with emotional distress in caregivers 1 year after stroke. METHODS: One-year stroke survivors with residual handicap (defined by the Oxford Handicap Scale) and their chief caregivers were interviewed as part of the follow-up activities for patients (n = 492) registered with the Perth Community Stroke Study. We assessed emotional distress in caregivers using the Hospital Anxiety and Depression Scale and the 28-item General Health Questionnaire. Appropriate sections of the Social Behaviour Assessment Schedule were used to assess the patient's behavior and the impact on the caregiver's life. Other aspects of the patient's functional state were assessed with the Barthel Index, the Mini-Mental State Examination, the Frenchay Activities Index, and the Psychiatric Assessment Schedule (at 4 months after stroke). RESULTS: Of 241 patients who survived to 1 year after stroke and were living outside of an institution, 103 patients (43%; 95% confidence interval, 37% to 49%) were handicapped. Eighty-four patient/caregiver units were assessed from this latter group. Almost all caregivers reported adverse effects on their emotional health, social activities, and leisure time, and more than half reported adverse effects on family relationships. Forty-six caregivers (55%) showed evidence of emotional distress on either of the two screening instruments, particularly if they were caregiving for patients with dementia and/or abnormal behavior. There was no significant relationship between emotional illness among caregivers and the degree of patients' physical disability. CONCLUSIONS: In this population, the high level of emotional distress among caregivers of stroke patients suggests that many caregivers have unmet needs. Community services need to focus attention on the neuropsychological aspects of stroke patients and the social functioning of caregivers who support them.

Prevalence of depression after stroke: the Perth Community Stroke Study.

BACKGROUND: The Perth Community Stroke Study (PCSS) was a population-based study of the incidence, cause, and outcome of acute stroke. METHOD: Subjects from the study were assessed initially, by examination and interview, and at four- and 12-month follow-ups to determine differences in prevalence of depression between the sexes and between patients with first-ever and recurrent strokes. RESULTS: The prevalence of depressive illness four months after stroke in 294 patients from the PCSS was 23% (18-28%), 15% (11-19%) major depression and 8% (5-11%) minor depression. There were no significant differences between the sexes or between patients with first-ever and recurrent strokes. With a non-hierarchic approach to diagnosis of those with depression, 26% of men and 39% of women had an associated anxiety disorder, mainly agoraphobia. Nine per cent of male and 13% of female patients interviewed had evidence of depression at the time of the stroke. Twelve months after stroke 56% of the men were still depressed (40% major and 16% minor), as were 30% of the women (12% major and 18% minor). CONCLUSION: The prevalence of depression after stroke was comparable with that reported from other studies, and considerably less than that reported from in-patient and rehabilitation units.

Anxiety disorders after stroke: results from the Perth Community Stroke Study.

BACKGROUND: The prevalence of anxiety disorders in 294 patients who survived to four months in the Perth Community Stroke Study (Perth, Australia), and a follow-up of these patients at 12 months, are presented. METHOD: Diagnoses are described both in the usual DSM hierarchic format and by a non-hierarchic approach. Adoption of the hierarchic approach alone greatly underestimates the prevalence of anxiety disorders. RESULTS: Most cases were of agoraphobia, and the remainder were generalised anxiety disorder. The prevalence of anxiety disorders alone was 5% in men and 19% in women; in community controls, it was 5% in men and 8% in women. Adopting a non-hierarchic approach to diagnosis gave a prevalence of 12% in men and 28% in women. When those who showed evidence of anxiety disorder before stroke were subtracted, the latter prevalence was 9% in men and 20% in women. CONCLUSION: One-third of the men and half of the women with post-stroke anxiety disorders showed evidence of either depression or an anxiety disorder at the time of the stroke. At 12 month follow-up of 49 patients with agoraphobia by a non-hierarchic approach, 51% had recovered, and equal proportions of the remainder had died or still had agoraphobia. The only major difference in outcome between those with anxiety disorder alone and those with comorbid depression was the greater mortality in the latter.

Validation of a clinical classification for subtypes of acute cerebral infarction.

The validity of a clinical classification system was assessed for subtypes of cerebral infarction for use in clinical trials of putative stroke therapies and clinical decision making in a population based stroke register (n = 536) compiled in Perth, Western Australia in 1989-90. The Perth Community Stroke Project (PCSS) used definitions and methodology similar to the Oxfordshire Community Stroke Project (OCSP) where the classification system was developed. In the PCSS, 421 cases of cerebral infarction and primary intracerebral haemorrhage (PICH), confirmed by brain imaging or necropsy, were classified into the subtypes total anterior circulation syndrome (TACS), partial anterior circulation syndrome (PACS), lacunar syndrome (LACS), and posterior circulation syndrome (POCS). In this relatively unselected population, relying exclusively on LACS for a diagnosis of PICH had a very low sensitivity (6%) and positive predictive value (3%). Comparison of the frequencies and outcomes (at one year after the onset of symptoms) for each subgroup of first ever cerebral infarction in the PCSS (n = 248) with the OCSP (n = 543) registers showed uniformity only for LACI. For example, there were 27% of cases of TACI in the PCSS compared with 17% in the OCSP (difference = 10%; 95% confidence interval (95% CI) 4% to 16%) and 15% of cases in the PCSS compared with 24% in the OCSP were POCI (difference = 9%; 95% CI 3% to 15%). Case fatalities and long-term handicap across the subgroups were not significantly different between studies, but the frequencies of recurrent stroke were significantly greater for POCI in the OCSP compared with the PCSS. Although this classification system defines subtypes of stroke with different outcomes, simple clinical measures-level of consciousness, paresis, disability, and incontinence at onset-are more powerful predictors of death or dependency at one year. It is concluded that simple clinical measures that reflect the severity of the neurological deficit should complement this classification system in clinical trials and practice.

Spectrum of primary intracerebral haemorrhage in Perth, Western Australia, 1989-90: incidence and outcome.

In a population based register of stroke (n = 536) compiled in Perth, Western Australia during an 18 month period in 1989-90, 60 cases (11%) of primary intracerebral haemorrhage were identified among 56 persons (52% men). The mean age of these patients was 68 (range 23-93) and 46 (77%) events were first ever strokes. The crude annual incidence was 35 per 100,000, with a peak in the eighth decade, and a male predominance. Deep and lobar haemorrhages each accounted for almost one third of all cases. The clinical presentations included sudden coma (12%), headache (8%), seizures (8%), and pure sensory-motor stroke (3%). Primary intracerebral haemorrhage was the first presentation of leukaemia in two cases (both fatal) and it followed an alcoholic binge in four cases. 55% had a history of hypertension. 16 (27%) patients, half of whom had a history of hypertension, were taking antiplatelet agents, and one patient was taking warfarin. There were only two confirmed cases of amyloid angiopathy. The overall 28 day case fatality was 35%, but this varied from 100% for haemorrhages in the brainstem to 22% for those in the basal ganglionic or thalamic region. Other predictors of early death were intraventricular extension of blood, volume of haematoma, mass effect, and coma and severe paresis at onset. Although based on small numbers, these data confirm the heterogeneous nature of primary intracerebral haemorrhage, but they also suggest a different clinical spectrum of this type of stroke in the community compared with the experience of specialist neurological units.

The role of lifestyle factors in the etiology of stroke. A population-based case-control study in Perth, Western Australia.

BACKGROUND AND PURPOSE: We sought to examine risk factors for all strokes and for ischemic stroke and primary intracerebral hemorrhage separately. METHODS: This was a population-based case-control study. Each case subject meeting World Health Organization criteria for stroke (n = 536) from a population-based register of acute cerebrovascular events compiled in Perth, Western Australia, in 1989 to 1990 was matched for age and sex with up to five control subjects drawn from the same geographical area. Objective confirmation of the type of stroke was available from computed tomography, magnetic resonance imaging, or necropsy for 86% of the case subjects. Data on medical history and lifestyle factors were collected from case and control subjects by interview of the subject or a proxy informant. RESULTS: Current smoking, consumption of meat more than four times weekly, and a history of hypertension or intermittent claudication were each associated with increased risk in multivariate models for all strokes and for all first-ever strokes. Consumption of 1 to 20 g/d alcohol in the preceding week was associated with a significant reduction in the risk of all strokes, all ischemic strokes, and of primary intracerebral hemorrhage, while eating fish more than two times per month appeared to protect against first-ever stroke and against primary intracerebral hemorrhage. Diabetes mellitus was associated with a significantly increased risk of ischemic stroke but a decreased risk of hemorrhagic stroke. CONCLUSIONS: Risk factors for ischemic and hemorrhagic stroke are not exactly the same. Changes in lifestyle relating to tobacco and diet might make important contributions to further reductions in the incidence of stroke.

Predicting survival for 1 year among different subtypes of stroke. Results from the Perth Community Stroke Study.

BACKGROUND AND PURPOSE: Few studies have evaluated the factors influencing or predicting long-term survival after stroke in an unselected series of patients in whom the underlying cerebrovascular pathology is clearly defined. Moreover, the relative importance of risk factors for stroke, including sociodemographic and premorbid variables, has not been described in detail. METHODS: The study cohort consisted of 492 patients with stroke who were registered with a population-based study of acute cerebrovascular disease undertaken in Perth, Western Australia, during an 18-month period in 1989 and 1990. Objective evidence of the pathological basis of the stroke was obtained in 86% of cases, and all deaths among patients during a follow-up of 1 year were reviewed. RESULTS: One hundred twenty patients (24%) died within 28 days of the onset of stroke. Among the different subtypes of stroke, the 1-year case fatality (mean, 38%) varied from 6% and 16% for boundary zone infarction and lacunar infarction, respectively, to 42% and 46% for subarachnoid hemorrhage and primary intracerebral hemorrhage, respectively. Using Cox proportional-hazards analysis, a predictive model was developed on 321 patients with acute stroke (test sample). The best model contained five baseline variables that were independent predictors of death within 1 year: coma (relative risk [RR], 3.0; 95% confidence interval [CI], 1.1 to 8.4), urinary incontinence (RR, 3.9; 95% CI, 1.4 to 10.6), cardiac failure (RR, 6.5; 95% CI, 2.8 to 15.1), severe paresis (RR, 4.9; 95% CI, 1.6 to 15.5), and atrial fibrillation (RR, 2.0; 95% CI, 1.1 to 3.5). The sensitivity, specificity, and negative predictive value of this model for predicting death were 90%, 83%, and 95%, respectively. When applied to a second randomly selected validation sample of 171 events, sensitivity was 94%, specificity 62%, and negative predictive value 92%, indicating stability of the model. CONCLUSIONS: Although the case fatality, timing, and cause of death vary considerably among the different pathological subtypes of stroke, simple clinical measures that reflect the severity of the neurological deficit and associated cardiac disease at onset independently predict death by 1 year and may help to direct management.

Stroke incidence and case fatality in Australasia. A comparison of the Auckland and Perth population-based stroke registers.

BACKGROUND AND PURPOSE: Population-based studies are crucial for identifying explanations for the decline in mortality from stroke and for generating strategies for public health policy. However, the present particular methodological difficulties, and comparability between them is generally poor. In this article we compare the incidence and case fatality of stroke as assessed by two independent well-designed incidence studies. METHODS: Two registers of acute cerebrovascular events were compiled in the geographically defined metropolitan areas of Auckland, New Zealand (population 945,369), during 1991-1992 for 12 months and Perth, Australia (population 138,708), during 1989-1990 for 18 months. The protocols for each register included prospective ascertainment of cases using multiple overlapping sources and the application of standardized definitions and criteria for stroke and case fatality. RESULTS: In Auckland, 1803 events occurred in 1761 residents, 73% of which were first-ever strokes. The corresponding figures for Perth were 536 events in 492 residents, 69% of which were first-ever strokes. Both studies identified a substantial proportion of nonfatal strokes managed solely outside the hospital system: 28% in Auckland and 22% in Perth of all patients registered. The age-standardized annual incidence of stroke (all events) was 27% higher among men in Perth compared with Auckland (odds ratio, 1.27; P = .016); women tended to have higher rates in Auckland, although these differences were not statistically significant. In both centers approximately a quarter of all patients died within the first month after a stroke. There were significant differences in the prevalence of hypertension among first-ever strokes. CONCLUSIONS: These two studies emphasize the importance of identifying all patients with stroke, both hospitalized and nonhospitalized, in order to measure the incidence of stroke accurately. The incidence and case fatality of stroke were remarkably similar in Auckland and Perth in the early 1990s. However, there are differences in the sex-specific rates that correspond to differences in the pattern of risk factors.

Ascertaining the true incidence of stroke: experience from the Perth Community Stroke Study, 1989-1990.

OBJECTIVE: To determine the age and sex specific incidence, and case fatality of stroke in Perth, Western Australia. DESIGN AND SETTING: A population-based descriptive epidemiological study. SUBJECTS: All residents of a geographically defined segment of the Perth metropolitan area (population 138,708) who had a stroke or transient ischaemic attack between 20 February 1989 and 19 August 1990, inclusive. MAIN OUTCOME MEASURES: Definite acute "first-ever-in-a-lifetime" (first-ever) and recurrent stroke classified according to standard definitions and criteria. RESULTS: During the 18-month study period, 536 stroke events occurred among 492 patients, 69% of which were first-ever strokes. The crude annual event rate for all strokes was 258 (95% confidence interval 231-285) per 100,000, and the overall case fatality at 28 days was 24% (95% CI, 20%-28%). The crude annual incidence for first-ever strokes was 178 (95% CI, 156-200) per 100,000; 189 (95% CI, 157-221) per 100,000 in males and 166 (95% CI, 136-196) per 100,000 in females. The corresponding rates, age-adjusted to the "world" population, were 132 (95% CI, 109-155) for males and 77 (95% CI, 60-94) for females. CONCLUSIONS: In contrast to mortality rates for ischaemic heart disease, the incidence of stroke in Australia appears little different from that for several other Western countries. For both males and females the incidence of stroke rises exponentially with increasing age. Although the sex-dependent difference in the risk of stroke is greatest in middle age, males are at greater risk of stroke even among the most elderly. To determine the incidence of stroke accurately, population-based studies of stroke need exhaustive and overlapping sources of case ascertainment. If only cases admitted to hospital had been used, we would have underestimated the rate of stroke among the most elderly by almost 40%. We estimate that approximately 37,000 people, about 50% of whom are over the age of 75, suffer a stroke each year in Australia.

Determining the incidence of different subtypes of stroke: results from the Perth Community Stroke Study, 1989-1990.

OBJECTIVE: To determine the incidence and case fatality of seven distinct subtypes of stroke in Perth, Western Australia. DESIGN AND SETTING: A population-based descriptive epidemiological study. SUBJECTS: All residents of a geographically defined segment of the Perth metropolitan area (estimated population 138,708 persons) who had a stroke or transient ischaemic attack between 20 February 1989 and 19 August 1990, inclusive. MAIN OUTCOME MEASURES: The following subtypes of stroke were classified according to standard clinical, radiological and pathological criteria: types of cerebral infarction, namely, large artery (thrombotic) occlusive infarction (LAOI), cerebral embolic infarction (EMBI), lacunar infarction (LACI) and boundary zone infarction (BZI); primary intracerebral haemorrhage (PICH); subarachnoid haemorrhage (SAH); and stroke of undetermined cause. RESULTS: Over the 18-month study period 536 stroke events were registered, of which 86% (95% confidence interval, 83%-89%) had a defined "pathological" diagnosis on the basis of computed tomographic scanning, magnetic resonance imaging or necropsy. Cerebral infarction accounted for 71% of cases (95% CI, 68%-75%), PICH 11% (95% CI, 9%-14%) and SAH 4% (95% CI, 2%-5%). The 382 cases of cerebral infarction included LAOI (in approximately 71%), EMBI (15%), LACI (10%) and BZI (5%). While the incidence of all subtypes of stroke increased with age, there were age and sex differences in their proportional frequency, management and prognosis: patients with PICH, SAH and EMBI were more likely to be admitted to hospital, and these conditions carried the highest early case fatality. Over all, the 28-day case fatality was 24% (95% CI, 20%-28%), but varied from 0 for LACI and BZI, to 37% (95% CI, 15%-59%) for SAH and 35% (CI, 23%-47%) for PICH. CONCLUSIONS: In this study, we found considerable differences in incidence rates, the effect of age and sex on incidence rates, and prognosis for the different subtypes of stroke. Hospital-based studies are likely to be selectively biased by emphasising strokes that are severe and require admission to hospital. These data have important implications in the design and evaluation of clinical trials of therapy for stroke.

Role rehearsal and efficacy: two 15-month evaluations of a ninth-grade alcohol education program.

A ninth-grade alcohol education program aimed at reducing drinking, drinking and driving, and riding with a drinking driver was developed on the basis of problem behavior theory, social cognitive theory and role theory. In Year 1 the program was taught by Social Studies teachers to half of the eighty-four ninth-grade classes in all nine junior high schools in a single school system; the other half served as controls. In Year 2 the program was taught to the ninth-grade students of the same school system by English teachers. Students' knowledge, skills and practices were measured before and four-six weeks and one year after the program. Results indicated significant increases in knowledge and perceived ability to resist pressures to drink among experimental students. No significant differences were noted for the drinking or the drinking and driving practices of either group. One year after the program, significantly fewer students in the experimental classes reported riding with a driver who had been drinking. Results suggested that English teachers were more effective than Social Studies teachers in teaching this program.

Predicting survival after stroke: experience from the Perth Community Stroke Study.

Survival is the most fundamental measure of the outcome from stroke, the magnitude of the burden being strongly reflected in case-fatality and survival rates. Although the literature is rich with follow-up studies examining survival after stroke, most are based on selected series of patients and factors which correlated with time to death have usually been determined in univariate analyses. We examined the factors associated with a high risk of death during the acute phase of stroke. Analyses were based on data from a population based study of acute cerebrovascular disease undertaken in Perth, Western Australia, during an 18 month period 1989-1990. Using logistic regression modelling techniques only 2 factors, severe loss of consciousness, odds ratio 14.7 [95% confidence limits (CL), 4.0-53.6], and severe paresis, odds ratio 7.2 [95% CL, 1.6-32.0], independently predicted death by 28 days after the onset of stroke. The implication is that 2 simple measures, level of consciousness and motor power, may help direct management. Furthermore, age is not an independent risk factor for death early after stroke. Therefore the elderly should not be denied therapy purely on the basis of their age.

Metabolism and bacterial mutagenicity of binary mixtures of benzo(a)pyrene and polychlorinated aromatic hydrocarbons.

The results of both the Salmonella/microsome mutagenicity assay and high-performance liquid chromatography (HPLC) analysis were used to evaluate the interactions of binary mixtures of benzo(a)pyrene (BAP) and several different polychlorinated aromatic hydrocarbons. Binary mixtures of either 2-nitro-3,7,8-trichlorodibenzo-p-dioxin (2NTCDD) or pentachlorophenol (PCP) with BAP produced synergism, whereas strictly additive effects were observed with mixtures of octa- or hepta-chlorodibenzo-p-dioxin and BAP. At a dose of 50 micrograms per plate, BAP induced 120 total revertants, whereas the binary mixture of BAP and PCP induced 303 total revertants. The binary mixture of BAP at 1 microgram per plate and 2NTCDD at 0.5 microgram per plate induced 261 net revertants, whereas BAP alone induced 42 net revertants. HPLC analysis of the mixtures indicated that preincubation of BAP with 2NTCDD increased the quantity of benzo(a)pyrene-7,8-dihydrodiol, and 9,10-dihydrodiol metabolites detected. The data suggest that nonmutagenic components of a complex mixture may alter the metabolism of promixate mutagens. Thus, in the present study, 2NTCDD appears to have inhibited the detoxication of BAP metabolites.

The influence of application rate on the bacterial mutagenicity of soil amended with municipal sewage sludge.

The mutagenic potential of two soils amended with a municipal sewage sludge at two application rates was monitored over a 2-year period using Salmonella/microsome mutagenicity assay. Samples were collected from undisturbed monolith lysimeters of Weswood sandy clay (Fluventic Ustochrept) and Padina sandy loam (Grossarenic Paleustalf) amended with dried sewage sludge at 50 and 100 Mg/ha. Soil samples were collected and sequentially extracted with methylene chloride and methanol. The residues from these extracts were tested for mutagenicity at five doses with and without metabolic activation in Salmonella strain TA98. In general, the mutagenic potential of the amended soils of both application rates for the first 8 weeks following sludge application increased and then slowly decreased. The maximum mutagenic response observed in the soil extracts was 222 revertants at a dose of 10 mg of residue. This response was induced by the methanol extract from the Weswood soil collected 56 days after the application of 50 Mg/ha sewage sludge as compared to the 100 Mg/ha application which induced 202 revertants/mg. The mutagenicity of all fractions extracted from the sludge-amended soil at both application rates collected 717 days after application were not appreciably different from extracts from the unamended soils. The data indicate that chemicals that were mutagenic in bacteria persist in the soil and that at the higher application rates, as much as 2 years may be required for the mutagenic potential of the soil to return to background levels.

Assays for total and antigen-specific polymeric IgA in serum based on binding to secretory component.

Binding assays with secretory component (SC) were used to detect polymeric IgA antibody to E. coli lipopolysaccharide and to estimate total polymeric IgA in sera from 14 patients with alcoholic liver disease and eight normal controls. Radioiodinated human SC was shown to bind to polymeric IgA and IgM but not to monomeric IgA, secretory IgA or IgG. Serum aliquots (0.5 ml) were totally depleted of IgM using 2 ml anti-IgM affinity columns and the effluent sera were titrated in microtitre plates coated with lipopolysaccharide, the binding of polymeric IgA being detected by adding 10 ng radiolabelled SC. Total polymeric IgA was measured via its capacity to inhibit the binding of 5 ng labelled SC to IgM coated wells, quantitation being achieved by comparison with the inhibition produced by purified polymeric IgA. Total lipopolysaccharide-specific IgA antibody was detected by ELISA in sera from both patients and controls, 1185 +/- 793 and 56 +/- 19 U/100 microliters (mean +/- SD), respectively; but polymeric IgA antibody was detected only in patients' sera (131 +/- 214 U/100 microliters). The concentration of total polymeric IgA was higher in patients' sera than in control sera (488 +/- 333 and less than 120 micrograms/ml respectively).

Treatment of malignancy-associated hypercalcemia with norethisterone: a case report.

Hypercalcemia is a common cause of morbidity in cancer patients. The mechanism of malignancy-associated hypercalcemia includes increased bone resorption and decreased renal calcium clearance which also occur in primary hyperparathyroidism. Norethisterone can inhibit bone resorption and has recently been shown to be effective treatment for mild hyperparathyroidism in post menopausal women. We report the successful use for the first time of norethisterone (5 mg daily) in a case of malignancy-associated hypercalcemia after other standard agents failed.

Hepatic granulomas: a 15-year experience in the Royal Adelaide Hospital.

The clinical and pathological associations of hepatic granulomas in patients who presented to the Royal Adelaide Hospital between January 1, 1968 and February 29, 1984 were reviewed retrospectively. Cases of primary biliary cirrhosis were excluded. Of 59 patients with hepatic granulomas, clear associations with diseases were identified in 42 (71%) patients. These were sarcoidosis (seven cases), chronic liver disease (12 cases), biliary tract disease (three cases), tuberculosis (four cases), Q-fever (three cases), other infections (four cases), drug hypersensitivity (four cases) and neoplasms (five cases). Ten patients had multiple associations and five other patients presented without any clearly defined cause for granulomas. Three of these latter patients presented with an acute febrile illness, showed hepatomegaly and had abnormal results of liver function tests. These cases may represent the entity that is labeled "idiopathic granulomatous hepatitis". Two other patients abused alcohol. Granulomas were categorized morphologically as microgranulomas, macrogranulomas and lipogranulomas according to their size, organization and the presence of fat droplets. Microgranulomas were associated with diseases of short duration and less architectural disturbance of the liver parenchyma. The presence of granulomas did not confer any prognostic implication over and above that of the associated disease.
