The government's plans for multi-agency healthcare will be hampered by the variability of data available in different sectors. Data collection from private hospitals, clinics and nursing homes lags far behind the NHS. Unless data collection improves, no information will be available on the care provided to the 270,000 people expected to receive rehabilitation or intermediate care in nursing homes under the NHS plan. This lack of essential data will weaken mechanisms for control. 相似文献
Eighteen children aged 6 to 11 years old who fulfilled criteria for the diagnosis of neonatal meconium aspiration syndrome were investigated to find out the prevalence of previous and current respiratory symptoms, and abnormal pulmonary function tests, chest radiographs, and ventilation scans. Eleven of the 18 had no respiratory symptoms and eight of these had normal pulmonary function on testing. Two had mild limitation of expiratory airflow that did not respond to treatment with bronchodilators, and one had exercise induced bronchospasm that responded to treatment with bronchodilators. Seven of the 18 had recurrent cough and wheezing compatible with a diagnosis of asthma, and five of these had appreciable exercise induced bronchospasm that responded to treatment with bronchodilators. None of the children with symptoms had a personal or family history of atopy or had had acute bronchiolitis. All chest radiographs were normal. We found a much higher prevalence of asthmatic symptoms and abnormal bronchial reactivity among survivors of neonatal meconium aspiration syndrome than in the general childhood population. Aspiration of meconium may have long term consequences for the developing respiratory tract and is associated with abnormal respiratory function in later childhood. 相似文献
Mortality data on Gulf War veterans was reviewed as a means of evaluating the long term consequences of the war. Studies were located from searches of Medline, Proceedings of the Conference on Federally Sponsored Gulf War Veterans' Illnesses Research, Proceedings of the American Public Health Association Annual Meetings, Annual Reports to Congress, and personal contacts with knowledgeable investigators. Data on study design, methods, and results were obtained from published studies of both US and UK veterans who served in the Persian Gulf. The methodology and results of studies are summarised and evaluated. Additional research recommendations based on reviewed studies are presented. It is concluded that in both US and UK studies, mortality from external causes was higher, while mortality from all illnesses was lower among Gulf War veterans in comparison to those of non-Gulf War veterans. Increased mortality from external causes is consistent with patterns of postwar mortality observed in veterans of previous wars. Further follow up of Gulf War veterans and their controls is warranted for evaluating the mortality risk from diseases with longer latency periods. 相似文献
OBJECTIVE: To determine whether reported widespread body pain is related to an increased incidence of cancer and/or reduced survival from cancer, since our previous population surveys have demonstrated a relationship between widespread body pain and a subsequent 2-fold increase in mortality from cancer over an 8-year period. METHODS: A total of 6565 subjects in Northwest England participated in 2 health surveys during 1991-1992. The subjects were classified according to their reported pain status (no pain, regional pain, and widespread pain), and were subsequently followed up prospectively until December 31, 1999. During followup, information was collected on incidence of cancer and survival rates among those developing cancer. Associations between the original pain status and development of cancer and cancer survival were expressed as the incidence rate ratio (IRR) and mortality rate ratio (MRR), respectively. All analyses were adjusted for age, sex, and study location, the latter being a proxy measure of socioeconomic status. RESULTS: Among the study population, 6331 had never been diagnosed with cancer at the time of participation in the survey. Of these subjects, 956 (15%) were classified as having widespread pain, 3061 (48%) as having regional pain, and 2314 (37%) as having no pain. There were a total of 395 first malignancies recorded during followup. In comparison with subjects reporting no pain, those with regional pain (IRR 1.19, 95% confidence interval [95% CI] 0.94-1.50) and widespread pain (IRR 1.61, 95% CI 1.21-2.13) experienced an excess incidence of cancer during the followup period. The increased incidence among subjects previously reporting widespread pain was related, most strongly, to breast cancer (IRR 3.67, 95% CI 1.39-9.68), but there were also cancers of the prostate (IRR 3.46, 95% CI 1.25-9.59), large bowel (IRR 2.35, 95% CI 0.96-5.77), and lung (IRR 2.04, 95% CI 0.96-4.34). Subjects reporting widespread pain who subsequently developed cancer, in comparison with those previously reporting no pain, had an increased risk of death (MRR 1.82, 95% CI 1.18-2.80). This decreased survival was highest among subjects with cancers of the breast and prostate, although the effects on site-specific survival were nonsignificant. CONCLUSION: This study has demonstrated that widespread pain reported in population surveys is associated with a substantial subsequent increased incidence of cancer and reduced cancer survival. At present there are no satisfactory biologic explanations for this observation, although several possible leads have been identified. 相似文献
OBJECTIVE: In an unselected community sample of adults, to assess the role and importance of exposure to mechanical factors both at work and leisure in the aetiology of hip pain. METHOD: A population based prevalence case-control study. Cases and controls were identified from a population survey of 3847 subjects registered with two general practices in Cheshire, United Kingdom. All subjects received a postal questionnaire which inquired about hip pain during the past month. An occupational history was obtained, including exposure to each of seven physical demands. Information was also obtained on history of participation in eight common sporting activities. RESULTS: 88% of those invited to participate returned a completed questionnaire. The 352 subjects with hip pain were designated as cases, and the remaining 3002 subjects as controls. In people ever employed, hip pain was significantly associated with high cumulative workplace exposure (before onset) of walking long distances over rough ground, lifting/moving heavy weights, sitting for prolonged periods, walking long distances, frequent jumping between different levels, and standing for prolonged periods. Odds ratios (ORs) in the higher exposure categories ranged from 1.46 to 2.65. Cumulative exposure to three sporting activities was significantly associated with hip pain: track and field sports, jogging, and walking, with odds ratios varying between 1.57 to 1.94. On multivariate analysis three factors were independent predictors of hip pain onset: cumulative exposure of sitting for prolonged periods (higher exposure v not exposed: OR=1.82, 95% confidence interval (CI) 1.13 to 2.92), lifting weights >50 lb (23 kg) (OR=1.74, 95% CI 1.06 to 2.86) (both relating to the workplace), and walking as a leisure activity (OR=1.97, 95% CI 1.32 to 2.94). The population attributable risk associated with each of these activities was 21%, 13%, and 16%, respectively CONCLUSIONS: Cumulative exposure to some workplace and sporting "mechanical" risk factors for hip osteoarthritis (OA) appear to be related to hip pain in general-some (but not all) have previously been related to hip OA. Because these are common workplace or leisure time activities their attributable risk is high. 相似文献
Objectives. The aetiology of orofacial pain (OFP) is not well understood. We aimed to determine the relationship between OFP and local mechanical factors in an unselected general population sample.
Methods. A cross-sectional population-based survey was conducted in the United Kingdom, involving 2504 participants (adjusted participation rate 74%). Postal questionnaire was used to collect information on OFP and local mechanical factors.
Results. A significant association was found between OFP and a history of tooth grinding, facial trauma, the jaw getting stuck or locked, a clicking or grating sound in the jaw joint when opening or closing the mouth, difficulty in opening the mouth wide, and chewing of pens or biting finger nails. The jaw getting stuck or locked had the highest relative risk of 2.7 (95% CI: 2.3–3.2). A history of orthodontic treatment, having any type of dentures and using chewing gum were not associated with OFP. There was some evidence of heterogeneity between types of OFP and local mechanical factors.
Conclusions. Local factors play an important role in the aetiology of OFP. 相似文献
BACKGROUND: The present study was undertaken to test the effectiveness of an established equation for estimating the probability of acute cardiac ischaemia, but in an environment different from that in which it was developed. METHODS AND RESULTS: A total of 255 patients who presented to the accident and emergency department of Glasgow Royal Infirmary with symptoms suggesting acute ischaemic heart disease were enrolled in the study. Their clinical data and ECG measurements were used as input to the Time-Insensitive Predictive Instrument (TIPI) equation to calculate the probability of acute myocardial ischaemia being present. Receiver operating characteristic (ROC) curves were derived to evaluate the usefulness of the equation in diagnosing acute myocardial infarction versus nonmyocardial infarction and acute cardiac ischaemia verses nonischaemic chest pain. For the diagnosis of acute cardiac ischaemia versus noncardiac chest pain, the area under the ROC curve was 0.61 (95% CI 0.55-0.67). For the diagnosis of acute myocardial infarction versus nonmyocardial infarction, there was increased performance with the area under the ROC curve being 0.71 (95% CI 0.65-0.76). This compares with the originally published findings of a value of 0.88 for the area under the curve for the diagnosis of acute myocardial ischaemia versus noncardiac chest pain. CONCLUSION: The study suggests that equations for the diagnosis of acute cardiac ischaemia developed in one centre may not readily translate elsewhere, possibly due to varying interpretations of the clinical and ECG criteria used. 相似文献
