Domains rated as important by patients with hand osteoarthritis.

BACKGROUND: No data exist on patient participation in the selection of core domains for clinical trials of hand osteoarthritis (HOA). We aim to explore HOA patients' perspectives in the relative importance of domains. METHODS: Seven domains affecting patients' lives were derived from a prior qualitative study. We recruited consecutive patients with symptomatic HOA to rate on 11-point numeric rating scales for each domain, from 0 representing "not important at all" to 10 representing "most important", with consideration in two scenarios: (a) how important the domains are in affecting their current lives; and (b) how important the domains are when there are treatments for HOA (eg exercise or drugs). RESULTS: Forty-five patients (91% female; mean age ± standard deviation 64.3 ± 7.5 years) with mild HOA symptoms were included. Of these, 31%-42% rated current impact of HOA in various domains as highly important. Seven domains with rated scores of ≥7/10 in importance were endorsed for clinical trials in the following order: pain and HOA symptoms (endorsed by 77.8% of patients), physical function (66.7%), ability to participate in social roles (64.4%), ability to participate in social activities (62.2%), work productivity (62.2%), emotional health (60%), and appearance of fingers (55.6%). CONCLUSION: The preliminary important domains as endorsed by patients with HOA for inclusion into clinical trials were explored. Apart from pain and physical function, further research is needed to refine other domains of impact, such as participation, emotional health and aesthetic concerns, as core domain sets for HOA.

Age-Specific Associations of Renal Impairment and Cerebral Small Vessel Disease Burden in Chinese with Ischaemic Stroke.

BACKGROUND: Recent studies in Caucasians with transient ischaemic attack or ischaemic stroke have demonstrated significant age-specific associations between cerebral small vessel disease (SVD) burden on magnetic resonance imaging and renal impairment. We aimed to validate these findings in a large cohort of Chinese with ischaemic stroke. METHODS: In 959 Chinese with ischaemic stroke who received a brain magnetic resonance imaging at the University of Hong Kong, we determined the age-specific associations of renal impairment (glomerular filtration rate < 60 mL/min/1.73 m2) with neuroimaging markers of SVD as well as with the SVD score. RESULTS: Although renal impairment was associated with the SVD score in univariate analysis in all patients (odds ratio 1.61, 95% confidence interval 1.24-2.09, P < .0001), these associations were attenuated after adjusting for age and sex (P = .38). Similar findings were noted in patients with ischaemic stroke due to SVD and non-SVD subtypes. However, in 222 of 959 patients aged <60, renal impairment was independently associated with an increasing microbleed (adjusted odds ratio 6.82, 2.26-20.59), subcortical (4.97, 1.62-15.24) periventricular white matter hyperintensity (3.96, 1.08-14.51) and global SVD burden (3.41, 1.16-10.04; all P < .05) even after adjusting for age, sex, and vascular risk factors. Nevertheless, there were no associations between renal impairment and individual neuroimaging markers of SVD nor with the SVD score in patients aged ≥60 after adjusting for age and sex (all P > .05). CONCLUSIONS: In Chinese with ischaemic stroke, renal impairment was independently associated with microbleed, white matter hyperintensity and global SVD burden in individuals aged <60, but not in those aged ≥60, suggesting that there may be shared susceptibilities to premature systemic disease.
