OBJECTIVE: To evaluate the effect of employment on health outcomes in a sample of women with rheumatoid arthritis (RA) and to test the hypothesis that employment confers a health benefit to women. METHODS: Seven hundred sixty women with a diagnosis of RA were recruited from a national random sample of private rheumatology practices in 1988, and 416 remained in the study after 7 years of followup in 1994. Women were interviewed each year by telephone to collect data on demographic variables, health status, and employment status. Clinical data were provided by referring physicians. RESULTS: Most women (175, 42%) were not employed outside the home 1988-94, although 96 of those women (23% of the sample) had been employed previously. Twenty-seven percent (n = 112) were employed all 7 years and 31% (n = 129) had been employed between one and 6 years. Women who were employed had significantly better health outcomes measured by pain, disability, role functioning, and clinical status compared to those who were never employed and those who had been employed before the study. Women who were previously employed, but not employed during the study period experienced the worst health outcomes. This difference in health status, however, appeared before entry into this study. CONCLUSION: Employed women with RA had better health status than women who were not employed outside the home. Previously employed women had worse health outcomes than both working women and women who were never employed, suggesting that loss of employment is associated with worse health. Further research is needed to investigate underlying factors contributing to worse health status among unemployed women and to better health among employed women. 相似文献

PURPOSE: We compared the ability of the CX and Ultrex cylinders to straighten the penis in men who received a 3-piece AMS 700 series inflatable penile prosthesis for erectile dysfunction and erectile deformity due to Peyronie's disease. MATERIALS AND METHODS: The records of 34 and 38 patients receiving devices CX and Ultrex cylinders, respectively, were reviewed. RESULTS: All 34 patients receiving the CX cylinders achieved complete penile straightening with cylinder inflation and bending alone. In 10 of 38 patients receiving the Ultrex cylinders complete straightening with cylinder inflation and bending could not be achieved, and simultaneous corporoplasty was necessary. CONCLUSIONS: Girth expanding CX cylinders have better penile straightening properties than girth and length expanding Ultrex cylinders. We recommend use of CX cylinders for 3-piece AMS 700 series inflatable penile prosthesis implantation in men with Peyronie's disease. 相似文献

OBJECTIVE: To determine the cumulative prevalences of wheeze and doctor diagnosed asthma and the point prevalences of recurrent cough and wheeze in children aged 5 years and under. DESIGN: Questionnaire survey of population based random sample of children registered on regional authority's child health index for immunisation; questionnaire completed by parents. SETTING: Leicestershire. SUBJECTS: 1650 white children born in 1985-9 who were surveyed in 1990. MAIN OUTCOME MEASURES: Cumulative prevalences of wheeze and doctor diagnosed asthma and point prevalences of recurrent cough and wheeze by age and sex. RESULTS: There were 1422 replies (86.2%; 726 for boys, 696 for girls). Overall, 11.0% (95% confidence interval 9.4% to 12.6%) of children had formally been diagnosed as having asthma, the cumulative prevalence in boys (12.7%) being somewhat higher than in girls (9.2%) (age adjusted odds ratio 1.47, p = 0.03). As expected, the cumulative prevalence of asthma increased significantly with age (7.5% (13/173) in children under 1 year, 15.9% (61/383) in children of 4 years and over; p < 0.001). The cumulative prevalence of wheeze overall was 15.6% (13.7% to 17.5%), being higher in boys (17.6%) than in girls (13.5%) (odds ratio 1.38, p = 0.03). The overall prevalence of recurrent cough without colds was 21.8% (19.6% to 23.9%), with a non-significant excess in boys (23.1% v 20.4%). The overall prevalence of wheezing attacks during the previous 12 months was 13.0% (11.3% to 14.8%) with a non-significant excess in boys (14.5% v 11.5%). CONCLUSIONS: These findings are baseline results and emphasise the importance of studying the age group of interest rather than relying on the recall of parents of school age children. 相似文献

That type 2 diabetes is a disease fulfilling most of the criteria justifying screening is argued in the article. Currently there are probably 50-100,000 cases of undiagnosed type 2 diabetes in Sweden, i.e., 6-12 per 1,000 of the population, a figure that could be substantially reduced by more consistent use of opportunistic screening in primary care. With good organisation of daily work routines, the screening itself need not require significantly more resources. However, satisfactory management of newly diagnosed patients may require further resources and other, more effective reception facilities, particularly if the more stringent diagnostic criteria adopted in the USA in 1997 are ratified by inclusion the WHO recommendations soon to be published. 相似文献

PURPOSE: To correlate the perirolandic low signal intensity seen on T2-weighted magnetic resonance (MR) images in neonates and infants with the anatomically located sensorimotor cortex. MATERIALS AND METHODS: Axial T2-weighted MR images of 146 consecutive patients less than 6 months old were reviewed. The sensorimotor cortex was located by identifying the central sulcus. Two independent readers attempted to identify the central sulcus using two anatomic methods independently and in combination. The location of the central sulcus was compared with that of the perirolandic low signal intensity. RESULTS: Seventy-two normal hemispheres in 36 patients and 91 abnormal hemispheres in 47 patients showed clear perirolandic low signal intensity. The central sulcus was located anatomically in 70 and 72 normal hemispheres (97% and 100%, respectively) and 90 and 91 abnormal hemispheres (99% and 100%, respectively). In all normal hemispheres, the identified central sulcus correlated with the perirolandic low signal intensity. In contrast, an apparent mismatch was found in two hemispheres in a patient with Dandy-Walker syndrome. CONCLUSION: The perirolandic low signal intensity seen on T2-weighted MR images is located exactly in the anatomic sensorimotor cortex in normal brains, whereas a mismatch can occur in abnormal brains. 相似文献

UDP-galactose 4-epimerase from yeast Kluyveromyces fragilis (Kluyveromyces marxianus var. marxianus) is a homodimer of molecular mass 75 kDa/subunit and has one mol NAD firmly bound/dimer. The pathway for the assembly of the holoenzyme structure has been studied after dissociating the native epimerase with p-chloromercuribenzoate into inactive mercurated monomers. The process of dissociation was not associated with unfolding of the molecules. Reconstitution of the functional holoenzyme was done by reduction with dithiothreitol and addition of extra NAD. The reaction was thus followed to monitor maturation of the enzyme from the folded monomeric state. The reconstituted enzyme was similar to the native enzyme in terms of a number of physiochemical properties such as secondary, tertiary and quarternary structures, Km for the substrate UDP-galactose, reductive inhibition, interaction with the fluorophore 1-anilino 8-naphthalene sulphonic acid (ANS), etc. Reconstitution under low ionic strength buffer (I = 0.011) shows that the presence of NAD is essential for the formation of a dimeric structure. However, dimeric apoenzyme could also be stabilized under high ionic strength buffer (I = 0.1). Reactivation was strongly dependent on pH, being most effective at pH 8.1. Kinetic evidence suggested that, at low ionic strength, assembly of NAD over dimeric apoenzyme is the rate-limiting step in expressing catalytic activity. This process has a low energy of activation of 27.2 kJ/mol. 相似文献
