The objectives of the study were to compare the association and responsiveness of the functional autonomy measurement system (SMAF) and functional independence measure (FIM) as outcome measures addressing functional independence in stroke patients involved in an intensive rehabilitation program and to compare their relationships with a social participation measure after rehabilitation period. One hundred and thirty-two people who had a stroke were evaluated with the SMAF and FIM during the rehabilitation period (T1: admission; T2: discharge; n=132) and twice after discharge (T3=2 weeks; n=118; T4=6 months later; n=102). At T3 and T4, a participation measure, the assessment of life habits (LIFE-H), was added. The main findings are: (1) the total scores on the SMAF and FIM are strongly correlated together (r=0.93 to 0.95; p<0.001); 2) the responsiveness of both functional independence scales is similar even though the SMAF total score is more responsive to change than the FIM total score (standardized response mean: 1.20 vs. 0.97; p<0.01); (3) the SMAF and FIM are related similarly to the daily activities domain of the participation scale; and finally (4) the social roles domain of the participation scale is less related to the SMAF and MIF than the daily activities domain; however, the SMAF score is more related to the social roles domain than the MIF. Our results support the need to use supplementary measures, such as participation measure, that cover not only physical function but also the other domains of participation, such as interpersonal relationships and leisure, that can be disrupted following a stroke. 相似文献
Monitoring airway inflammation by means of induced sputum cell counts seems to improve the management of asthma. We sought to assess whether such monitoring at the end of periods at and away from work combined with the monitoring of PEF could improve the diagnosis of occupational asthma. We enrolled subjects suspected of having occupational asthma. Serial monitoring of PEF was performed during 2 weeks at and away from work. At the end of each period, induced sputum was collected. Specific inhalation challenge was subsequently performed. PEF graphs were interpreted visually by five independent observers. Forty-nine subjects, including 23 with positive specific inhalation challenge, completed the study. The addition of sputum cell counts to the monitoring of PEF increased the specificity of this test, respectively, by 18 (range [r] 13.7-25.5) or 26.8% (r 24.8-30.4) depending if an increase of sputum eosinophils greater than 1 or 2% when at work was considered as significant. The sensitivity increased by 8.2% (r 4.1-13.4) or decreased by 12.3% (r 3.1-24.1) depending on the cutoff value in sputum eosinophils chosen (greater than 1 or 2%, respectively). The addition of sputum cell counts to PEF monitoring is useful to improve the diagnosis of occupational asthma. 相似文献
Our previous work demonstrated 2 quantitative trait loci (QTLs), C2QTL1 and C2QTL2, for blood pressure (BP) located on chromosome (Chr) 2 of Dahl salt-sensitive (DSS) rats. However, for a lack of markers, the 2 congenic strains delineating C2QTL1 and C2QTL2 could not be separated. The position of the C2QTL1 was only inferred by comparing 2 congenic strains, one having and another lacking a BP effect. Furthermore, it was not known how adjacent QTLs would interact with one another on Chr 2. In the current investigation, first, a critical chromosome marker was developed to separate 2 C2QTLs. Second, a congenic substrain was created to cover a chromosome fragment thought to harbor C2QTL1. Finally, a series of congenic strains was produced to systematically and comprehensively cover the entire Chr 2 segment containing C2QTL2 and other regions previously untested. Consequently, a total of 3 QTLs were discovered, with C2QTL3 located between C2QTL1 and C2QTL2. C2QTL1, C2QTL2, and C2QTL3 reside in chromosome segments of 5.7 centiMorgan (cM), 3.5 cM, and 1.5 cM, respectively. C2QTL1 interacted epistatically with either C2QTL2 or C2QTL3, whereas C2QTL2 and C2QTL3 showed additive effects to each other. These results suggest that BP QTLs closely linked in a segment interact epistatically and additively to one another on Chr 2. 相似文献
Objective: To evaluate the impact of amniotic fluid “sludge” (AFS) on the risk of preterm delivery and to describe the effect of antibiotic treatment in that situation.
Methods: Case–control study including singleton pregnancies with or without AFS, between 15–32 weeks of gestation. Factors associated with preterm delivery before 32 weeks, 34 weeks and 37 weeks were evaluated with univariate and multivariate logistic regression. Since all women with AFS in this study were treated with antibiotics, a historical comparison was performed with similar patients with AFS found before 2007 and not treated with antibiotics.
Results: AFS was observed in 90/1220 patients (7.4%). AFS was associated with shorter cervical length, greater body mass index, cervical cerclage and preterm birth before 28 weeks. However, after adjustment, AFS did not remain associated with preterm delivery before 32 or 34 weeks. The historical comparison suggested that azithromycin could significantly reduce the risk of preterm delivery before 34 weeks (odds ratio: 0.2; 95% CI: 0.04–0.92).
Conclusions: AFS, treated with azithromycin, was associated with a higher risk of prematurity, but not independently after adjustment for cervical length and second trimester vaginal bleeding. Further studies need to evaluate the effect of antibiotics in pregnancies with AFS. 相似文献
A new generation of ear thermometers with preheated tips and several measurements points should allow a more precise temperature measurement. The aim of the study was to evaluate if the ear temperature measured by this ear thermometer can be used to screen for fever and whether the thermometer is in agreement with the rectal temperature and if age, use of hearing devices or time after admission influences the temperature measurements.
Methods
Open cross-sectional clinical single site study patients, >?18?years old, who were acutely admitted to the short stay unit at the ED. A sample size of 99 patient per subgroup was recruited as random convenience series. As ear thermometer Braun Thermoscan Pro 4000® and as rectal thermometer Omron Flex Temp Smart ® was used. For different cut off of temperature the AUC was calculated and Bland-Altman analysis for calculation of 95% limits of agreement with rectal temperature, with subgroup analysis concerning age, time span from admission time and use of hearing aid.
Results
Among 599 patients the sensitivity to detect fever with an ear thermometer varied between 68 and 70% with AUC from 0.88–0.97. If the ear temperature was ≥37.5 oC, the sensitivity to detect patients with ≥38.0 oC rectally was 95% which raised to 100% for a rectal temperature of ≥38.3 oC. For the ear thermometer’s ability to determine the exact temperature the 95% limits of agreement were +/??0.8 oC. with no influence from age, duration of hospital stay or hearing aids.
Conclusion
The examined ear thermometer is able to detect fever, defined as ≥38 oC rectally in an adult ED population by using an ear cut-point of 37.5 oC, but not to measure the exact temperature. Used in this way around a fifth of the patients will still be in need of a rectal temperature measurement, but less than 5% with fever ≥38.0 oC will remain undetected and none with fever ≥38.3 oC. Age, admission time and use of hearing aid did not influence the temperature measurements.

Proteases have been postulated to account for the progressive disappearance of matrix proteoglycans in osteoarthritic (OA) cartilage. The digestion of endogenous proteoglycans by neutral proteases in human OA cartilage homogenates has been measured and compared with that of normal age-matched controls. Cartilage was obtained from 16 patients at the time of knee arthroplasty and from 7 accident victims. Tissue blocks were cut from the tibial plateau; part was used for histologic grading of the severity of OA and part was homogenized for the quantification of neutral metallo- and serine protease activities, based on the release of digested products from endogenous proteoglycans. Total metalloprotease activity (latent plus active forms) was elevated 3- to 10-fold in all diseased cartilage. This elevation was already significant in mild disease, but was greatest in samples of moderate to severe disease. The active form of the enzyme was highest at the center of erosions and decreased in the margins of the plateau. The digestion of proteoglycans, as distinct from their mere release from the tissue, was demonstrated by chromatography on Sepharose-CL2B and by large pore electrophoresis. Serine protease activity on proteoglycans was much lower than that of metalloprotease. The mean activity was highest in mild disease and declined in the severe disease samples, but the difference between these 2 groups and the controls was not statistically significant. The results of this study are consistent with the hypothesis that the neutral metalloproteases of cartilage are involved in the degradation of proteoglycans in osteoarthritis. 相似文献
Objective We have previously found that high levels of total IgE, but not atopic sensitization, was a significant predictor for functional gastrointestinal (GI) symptoms. In this study, we aimed to assess the prevalence of extra-intestinal symptoms in IBS patients, and explore their relation to total IgE levels and atopic sensitization. Materials and methods Seventy-one patients with functional GI complaints were included. Severity of GI symptoms, fatigue and musculoskeletal pain was evaluated using the following questionnaires: IBS-Severity Scoring System (IBS-SSS), Fatigue Impact Scale (FIS), FibroFatigue Scale (FFS), and Visual Analog Scales (VAS) for musculoskeletal pain. Levels of total IgE and specific IgE-antibodies were analyzed. Results Fatigue and musculoskeletal pain were demonstrated in 78.9 and 43.7% of the patients, respectively. IBS-SSS scores were significantly correlated with fatigue scores and musculoskeletal pain. Patients with fatigue and musculoskeletal pain had significantly higher IBS-SSS scores than patients without fatigue and musculoskeletal pain. Total IgE levels were significantly higher in IBS patients compared to a healthy control group from a previous study. However, neither total IgE nor atopic sensitization was significantly associated with extra-intestinal symptoms. Conclusions IBS, fatigue, and musculoskeletal pain were significantly associated. Total IgE levels were higher in IBS patients than healthy controls, but not related to intestinal or extra-intestinal symptom severity. Atopy was not associated with any of the co-morbidities. Thus, the clinical significance of high IgE levels in IBS remains unclear and further studies are warranted to explore a common underlying mechanism for the co-morbid triad of IBS, fatigue, and musculoskeletal pain. 相似文献
