Engelbert Lies Rombaut And the Pediatric Heritable Connective Tissue Disorders Study Group 《American journal of medical genetics. Part A》2023,191(7):1792-1803
The aim of the present study was to investigate the nature and prevalence of nonspecific somatic symptoms, pain and catastrophizing in children with Heritable Connective Tissue Disorders (HCTD), and to determine their association with disability. This observational, multicenter study included 127 children, aged 4–18 years, with Marfan syndrome (MFS) (59%), Loeys-Dietz syndrome (LDS) (8%), Ehlers-Danlos syndromes (EDS) (12%) and hypermobile Ehlers-Danlos syndrome (hEDS) (23%). The assessments included the Children's Somatization Inventory or parent proxy (CSI, PCSI), pain visual-analogue scale (VAS), SUPERKIDZ body diagram, Pain Catastrophizing Scale Child or parent proxy (PCS-C, PCS-P) and Childhood Health Assessment Questionnaire (CHAQ-30). Data from children aged ≥8 years were compared to normative data. In children ≥ 8 years (n = 90), pain was present in 59%, with a median of 4 (IQR = 3–9) pain areas. Compared to normative data, the HCTD group reported significantly higher on the CSI (p ≤ 0.001, d = 0.85), VAS pain intensity (p ≤ 0.001, d = 1.22) and CHAQ-30 (p ≤ 0.001, d = 1.16) and lower on the PCS-C (p = 0.017, d = −0.82) and PCS-P (p ≤ 0.001, d = −0.49). The intensity of nonspecific somatic symptoms and pain explained 45% of the variance in disability (r2 = 0.45 F(2,48) = 19.70, p ≤ 0.001). In children ≤ 7 years (n = 37), pain was present in 35% with a median of 5(IQR = 1–13) pain areas. The mean(SD) VAS scores for pain intensity was 1.5(2.9). Functional disability was moderately correlated to the number of pain areas (r = 0.56, p ≤ 0.001), intensity of nonspecific somatic symptoms (r = 0.63, p ≤ 0.001) and pain (r = 0.83, p ≤ 0.001). In conclusion, this study supports the need for comprehensive assessment of nonspecific somatic symptoms, pain, and disability in children with HCTD to allow tailored treatment. 相似文献

Objectives To synthesize the evidence on the psychometrics functional capacity evaluation (FCE) methods. Methods A systematic literature search in nine databases. The resulting articles were screened based on predefined in- and exclusion criteria. Two reviewers independently performed this screening. Included studies were appraised based on their methodological quality. Results The search resulted in 20 eligible studies about nine different FCE methods. The Baltimore Therapeutic Equipment work simulator showed a moderate predictive validity. The Ergo-Kit (EK) showed moderate variability and high inter- and intra-rater reliability. Low discriminative abilities and high convergent validity were found for the EK. Concurrent validity of the EK and the ERGOS Work Simulator was low to moderate. Moderate to high test–retest, inter- and intra-reliability was found in the Isernhagen Work-Systems (IWS) FCE. The predictive validity of the IWS was low. The physical work performance evaluation (PWPE) showed moderate test–retest reliability and moderate to high inter-rater reliability. Low internal and external responsiveness were found for the PWPE, predictive validity was high. The predictive validity of the short-form FCE was also high but need to be further examined on several psychometric properties. Low discriminative and convergent validity were found for the work disability functional assessment battery. The WorkHab showed moderate to high test–retest, inter- and intra-rater reliability. Conclusion Well-known FCE methods have been rigorously studied, but some of the research indicates weaknesses in their reliability and validity. Future research should address how these weaknesses can be overcome. 相似文献

Summary
The effect of niflumic acid on hyaluronic acid and proteoglycan metabolism of human cartilage cells was investigated in vitro. Cartilage cells were obtained from five different donors. Niflumic acid levels used in the test systems ranged from 0 to 22 gr/ml and were comparable to serum concentrations in humans after oral intake. Niflumic acid increased the synthesis rates of proteoglycan in some batches of isolated and monolayer-cultured chondrocytes. The effect on hyaluronate synthesis was less pronounced. The fact that this increase in the synthesis of proteoglycan was restricted to some of the donors whereas isolated cells or tissue samples from other individuals remained unaffected illustrates the heterogeneity of different human donors. Depression of proteoglycan synthesis in the presence of the drug was never observed. 相似文献

Human monkeypox is a zoonotic smallpox-like disease caused by an orthopoxvirus of interhuman transmissibility too low to sustain spread in susceptible populations. In February 1997, 88 cases of febrile pustular rash were identified for the previous 12 months in 12 villages of the Katako-Kombe Health Zone, Democratic Republic of Congo (attack rate = 22 per 1,000; case-fatality rate = 3.7%). Seven were active cases confirmed by virus isolation. Orthopoxvirus- neutralizing antibodies were detected in 54% of 72 patients who provided serum and 25% of 59 wild-caught animals, mainly squirrels. Hemagglutination-inhibition assays and Western blotting detected antibodies in 68% and 73% of patients, respectively. Vaccinia vaccination, which protects against monkeypox, ceased by 1983 after global smallpox eradication, leading to an increase in the proportion of susceptible people. 相似文献

The Abx Pentra 120 Retic, Coulter® General‐S?, Sysmex® SE 9500, Abbott Cell Dyn® 4000 and Bayer Advia® 120 were evaluated simultaneously in a general hospital laboratory. Linearity, precision, sample stability, carry‐over and comparability of the reticulocyte mode were determined following International Council for Standardization in Haematology guidelines for the evaluation of blood cell analysers. All analysers showed good results for dilution, stability and carry‐over testing. The between‐batch coefficient of variation of the General‐S? was high compared to the other analysers evaluated. Multiple correlation studies showed good agreement for all analysers in the normal and high reticulocyte range, with correlation coefficients above 0.7. Multiple correlation studies for reticulocytopenic samples (< 15.109/l) were less satisfactory, with a wider range of correlation coefficients (r‐values 0.0–0.9). Overall, the General‐S?, SE 9500 and Advia® 120 gave lower reticulocyte counts than the Pentra 120 Retic and CD 4000. Reagent costs were also evaluated. Reagent consumption was close to the manufacturers’ specifications for the SE 9500 (Search reagent), CD 4000 (CD Retic) and Advia® 120 (Retics) but was higher than stated for the Pentra 120 Retic (Retix), General‐S? (Retic kit) and SE 9500 (Sheath reagent). Our results show that these new generation haematology analysers will meet the needs of hospital laboratories for reliable and cost‐effective reticulocyte counting. 相似文献
