Stroke mortality--secular and geographic trends: comment on papers by Maheswaran and colleagues

Care of the dying stroke patient in the acute setting

Stroke is the third most common cause of death in England and Wales, accounting for 11% of all deaths. Predictors of early mortality following stroke have been known for over a century and include a history of stroke, age, disorientation to time and place and level of consciousness. To date, hospices and specialist palliative care services have focused on caring for terminally ill cancer patients, with 95% of their patients in 2000–2001 having cancer. However it has been acknowledged since its inception that the practices and principles of palliative care may be relevant to those dying from other conditions. Recently there has been a growing interest in palliative care for non-cancer diagnosis and increasing recognition that palliative care should be provided on the basis of need rather than diagnosis. Despite the high levels of mortality following stroke, to date, little has been published about dying from stroke. In this study we report on a prospective qualitative study of the nursing and medical care received by dying stroke patients.

Consumo alimentar de adolescentes com e sem sobrepeso do Município do Rio de Janeiro

Comparam-se, neste estudo, as características do consumo alimentar de uma amostra probabilística de adolescentes com sobrepeso e adolescentes com peso normal, com idades entre 12 e 17,9 anos. Os dados analisados foram obtidos em pesquisa realizada no Município do Rio de Janeiro, em 1995-1996. Estimou-se o consumo alimentar através de um questionário de freqüência do consumo de alimentos semiquantitativo. Avaliou-se o estado nutricional através do índice de massa corporal (IMC = peso/altura²), classificando-se os adolescentes com e sem sobrepeso pelo percentil 90 da distribuição do IMC de crianças brasileiras de 1989. O consumo de indivíduos com e sem sobrepeso foi semelhante, em ambos os grupos observou-se consumo inferior ao mínimo das porções recomendadas dos grupos alimentares e consumo elevado de alimentos de alta densidade energética. Esses hábitos alimentares propiciam o desenvolvimento de excesso de peso e podem ser determinantes de obesidade e doenças crônicas não transmissíveis na maturidade.

The incidence and aetiology of stroke in the Caerphilly and Speedwell Collaborative Studies I: methods and incidence of events

Stroke mortality and morbidity remain high despite downward trends in incidence and case fatality. Population-based longitudinal studies which include collection of risk factor data are required for a better understanding of stroke aetiology. From a representative cohort of men from South Wales and South-west England, followed up for a median of 17 y, details of possible cerebrovascular events were collected from questionnaires, hospital admission data, general practitioner records, death certificates, radiology records and post-mortem reports. Radiology records, and strokes and transient ischaemic attacks were independently validated. There were 433 strokes and 163 transient ischaemic attacks identified during follow-up. Of these, 333 were the first ever in a lifetime strokes of which 139 were definite ischaemic, 20 were haemorrhagic and 168 were probable ischaemic strokes. The crude incidence rate for stroke was 445 (95% confidence interval 398-493) per 100 000 person years. The age-standardised rates for 10 y age-bands were: 45-54 y 91 (10-172); 55-64 y 351 (269-432) and 65-74 y 855 (669-1040). The 30 d case-fatality rate was 21.0% (70/333) for all strokes and 19.2% (60/312) for ischaemic strokes. For transient ischaemic attacks the age-standardised incidence rates for the same 10 y age bands were 92 (4-179), 111 (64-157), and 273 (167-80), respectively. These rates for stroke transient ischaemic attack are likely to be accurate given the high ascertainment of events in this representative population of middle-aged men. Such studies, reporting reliable measures of cerebrovascular events, are important for measuring burden of disease, and for analysis of risk factor associations to help improve understanding of stroke aetiology and inform preventive efforts.

Social deprivation and prevalence of epilepsy and associated health usage

OBJECTIVES

To examine the relation between social deprivation and the prevalence of epilepsy and associated morbidity using hospital activity data as a proxy.

METHODS

The study was conducted in the health district of South Glamorgan, United Kingdom (population 434 000). Routinely available hospital data (inpatient and outpatient), an epilepsy clinic database, and mortality data underwent a process of record linkage to identify records relating to the same patient and to identify patients with epilepsy. Each patient was allocated a Townsend index deprivation score on the basis of their ward of residence. Age standardised correlations were calculated between deprivation score and prevalence of epilepsy, inpatient admissions, and outpatient appointments. Standardised mortality ratios (SMR) were also calculated. All analyses were performed on two cohorts: (1) all patients with epilepsy and (2) those patients with epilepsy without any underlying psychiatric illness or learning disability.

RESULTS

The prevalence of epilepsy ranged between 2.0 and 13.4 per 1000 with a median of 6.7. There were positive correlations between social deprivation and prevalence in both populations: (1) r=0.75 (p<0.001) and (2) r=0.70 (p<0.001). After standardising for underlying prevalence there were also correlations for mean inpatient admissions: (1) r=0.62 (p<0.001), (2) r=0.59, (p<0.001) and for outpatient appointments: (1) r=0.53, (p=0.001) and (2) r=0. 51 (p=0.001). The SMR for those deprived was (1) 1.66 (95% confidence interval (95% CI) 1.27-2.05) and (2) 1.80 (95% CI 0.71-1. 67). For the population as a whole (with and without epilepsy) the SMR was 1.25 (95% CI 1.27-2.32).

CONCLUSION

This study shows a strong correlation between the prevalence of epilepsy and social deprivation and weaker correlations between social deprivation and mean hospital activity.
