Objectives: The objective of this study was to explore the impact of balance confidence on different activities of daily living (ADL) in older people with knee osteoarthritis (OA).
Methods: Forty-seven consecutive participants with knee OA were included in this cross-sectional study. They were divided according to the results of the Activities-specific Balance Confidence (ABC) Scale into a group with a low level of confidence in physical functioning (ABC < 50, n = 22) and a group with moderate and high levels of confidence (ABC ≥ 50, n = 25).
Results: In the ABC < 50 group, the effect of pain on ADL, the physician’s global assessment of the disease, and the Western Ontario and McMaster Universities Osteoarthritis Index scores were significantly higher, while quality of life (Short form-36) was lower compared to the ABC ≥ 50 group. No significant difference was found between the two groups regarding the static and dynamic balance measurements.
Conclusions: Older people with knee OA who were less confident in their daily physical activities had more physical difficulties and a greater effect of pain on ADL, lower quality of life, and a higher physician’s global assessment, but no differences were obtained in balance tests.
Clinical Implications: In people with knee OA, decreased balance confidence is associated with more physical difficulties, an increased effect of pain on ADL, and lower quality of life. An improved awareness of decreased balance confidence may lead to more effective management of older people with knee OA by improving their mobility and QOL through rehabilitation. Furthermore, future research in that direction is warranted. 相似文献
Irritable bowel syndrome (IBS) is commonly regarded as a functional disorder, and is hypothesized to be associated with anxiety
and depression. This evidence mainly rests on population-based studies utilising self-report screening instruments for psychopathology.
Other studies applying structured clinical interviews are generally based on small clinical samples, which are vulnerable
to biases. The extant evidence base for an association between IBS and psychopathology is hence not conclusive. The aim of
this study was therefore to re-examine the hypothesis using population-based data and psychiatric morbidity established with
a structured clinical interview. 相似文献
Data suggest there are established socio-economic disparities associated with mental health although most research has focused on individual-level indicators of socio-economic position. The aim of this study was to investigate the association between mood disorders and area-based socio-economic status (SES), and whether both ends of the SES continuum experienced increased odds for a mood disorder.
Methods
Using a clinical interview (SCID-I/NP), psychiatric history was ascertained in a population-based sample of 1095 women (20–93 years) from the Barwon Statistical Division, south-eastern Australia. SES was determined by cross-referencing residential addresses with Australian Bureau of Statistics 2006 census data for the region and categorised into three groupings of low, mid, and upper SES. The Index of Economic Resources (IER), Index of Education and Occupation (IEO), and Index of Relative Socioeconomic Advantage/Disadvantage (IRSAD) were utilised. Lifestyle factors were self-reported.
Results
For IER, the low SES group had a 2.0-fold increased odds of a current mood disorder compared to the mid group, after adjustment for physical activity and current anxiety (OR = 2.0, 95% CI 1.0–4.1, p = 0.05). This pattern was similarly observed for IEO (OR = 1.8, 95% CI 0.9–3.7, p = 0.1) and IRSAD (OR = 1.6 95% CI 0.8–3.4, p = 0.2). Those within the upper SES group showed a non-significant increase in the odds of a current mood disorder compared to the mid-group; IER (OR = 1.4, 95% CI 0.8–2.5, p = 0.3), IEO (OR = 1.2, 95% CI 0.07–2.3, p = 0.5) and IRSAD (OR = 1.2, 95% CI 0.7–2.1, p = 0.6).
Conclusions
Women in the low SES category were most likely to have a mood disorder. Furthermore, being in an upper SES group may not be protective against mood disorders. 相似文献
BACKGROUND: To investigate the contribution of multidrug resistance 1 (MDR1) gene pharmacogenetics (G2677T/A and C3435T) to the efficacy of azathioprine in inducing remission in patients with Crohn's disease (CD). METHODS: A cohort of 327 unrelated Spanish patients with CD recruited from a single center was studied. All patients were rigorously followed up for at least 2 years (mean time, 11.5 years). A case-control analysis of MDR1 G2677T/A and C3435T SNPs and 2 loci haplotypes in 112 steroid-dependent CD patients treated with azathioprine was performed. Patients were classified on the basis of response to azathioprine. RESULTS: A total 76 patients treated with azathioprine for longer than 3 months were included. Remission was achieved in 42 CD patients (55.3%). A higher frequency of the 2677TT genotype was found in nonresponders than in responders (17.65% versus 7.14%; OR = 2.8; 95% CI; 0.6-12.1; P = 0.11). Nonresponders to azathioprine were found to have a higher frequency of the 3435TT genotype than did CD patients who had achieved clinical remission (17.64% versus 4.76%; OR = 4.3; 95% CI, 0.8-22.8; P = 0.06). The 2677T/3435T haplotype was also more abundant in nonresponders (29.4% versus 20.2%), whereas the 2677G/3435C haplotype was more frequent in responders (58.3% versus 47.1%). Lack of response to azathioprine therapy in CD patients was 1.8-fold greater in carriers of the 2677T/3435T haplotype than in carriers of the 2677G/3435C haplotype (OR = 1.8; 95% CI, 0.82-3.9; P = 0.14). CONCLUSIONS: The results of our study indicate higher frequencies of the 2677TT and 3435TT genotypes and the 2677T/3435T haplotype in CD patients who did not respond to azathioprine. Additional replications in independent populations would confirm the real impact of these polymorphisms in response to azathioprine therapy. 相似文献
PURPOSE OF REVIEW: In this article we summarize recent investigations into the influence of illness perceptions on outcomes in patients with medical conditions. RECENT FINDINGS: Developments in assessment include the publishing of a new brief scale to assess illness perceptions and the examination of the relationship between patient drawings of their illness and outcomes. Recent studies in primary care highlight the importance of patients' beliefs and emotional responses to their illness as being important in influencing their satisfaction with the consultation, reassurance following negative medical testing and future healthcare use. Recent research shows illness perceptions to have associations with a number of outcomes in chronic illness including self-management behaviours and quality of life. As yet, however, few interventions have been developed designed to change illness perceptions and improve illness outcomes. Emerging areas of research include the application of illness perceptions to mental illness and genetic and risk factor testing. SUMMARY: Research on illness perceptions has confirmed that patients' beliefs are associated with important outcomes in a broadening range of illnesses and risk factor testing. New interventions based on this model have the potential to improve patient outcomes but have yet to be widely developed and applied. 相似文献
The objective of this report is to explore the balance between serum and synovial fluid levels of interleukin (IL)-18 in children
with juvenile idiopathic arthritis (JIA). Blood samples were obtained from 81 children with JIA and 18 control children. Synovial
fluid samples were collected from 16 children with oligoarticular JIA. Concentrations of IL-18 were determined using commercial
kit. Patients with systemic JIA had higher serum levels of IL-18 than patients with other forms of JIA or control children,
both during the active (median, range: 6,240, 1,600–78,750 pg/ml) and inactive (1,615, 513–3,270 pg/ml) phase of disease [analysis
of variance (ANOVA), P < 0.05). Levels of IL-18 in sera of children with oligoarticular JIA (255, 89–4,342 pg/ml) were similar to the respective
synovial fluid levels (217, 89–1,245 pg/ml). Serum levels of IL-18 were proportional to the erythrocyte sedimentation rate
and levels of C-reactive protein, but inversely proportional to the haemoglobin levels. IL-18 appears to be an important mediator
of systemic JIA, while it seems of a lesser relevance in pathogenesis of other JIA forms. Therefore, inhibition of IL-18 might
be a base for a successful biological therapy for systemic JIA. 相似文献
PURPOSE: A prospective study was designed to determine if a screening quantitative serum D-dimer measurement of 1.0 microg/mL or less precludes pulmonary computed tomographic (CT) angiography in patients with possible acute pulmonary embolism (PE). MATERIALS AND METHODS: Over a period of 16 months, every patient seen in the emergency department in whom there was clinical suspicion of PE sufficient to warrant pulmonary CT angiography was also requested to have a quantitative serum D-dimer level measurement taken. All pulmonary CT angiography procedures were performed on a four-slice scanner and every examination was overread by a radiologist who was blinded to the D-dimer assay results. Three-month medical record and telephone follow-up was carried out for all participants who had a serum D-dimer level of 1.0 microg/mL or less to verify no new diagnosis or death from PE. RESULTS: In this prospective study, 361 consecutive patients who received pulmonary CT angiography had a D-dimer level of 1.0 microg/mL or less. There were 310 patients who had negative pulmonary CT angiography results and 50 patients who had indeterminate CT angiography results. Only one patient had positive pulmonary CT angiography findings. Minimum 3-month follow-up information was available for 349 patients, none of whom reported subsequent PE, including those with indeterminate pulmonary CT angiography results. CONCLUSION: The use of a screening D-dimer measurement of 1.0 microg/mL or less precludes pulmonary CT angiography in patients with possible acute PE. The use of this quantitative D-dimer assay would decrease radiation exposure, contrast medium toxicity, cost, and time for patients seen in the emergency medicine department. 相似文献
