MATERIALS AND METHODS: Twenty nine operations for skeletal metastasis of the femur performed in our centre between 2009 and 2015 were included in this study. We evaluated the choice of implant, complications, survival rate and functional outcome. Fourteen patients were still alive at the time of this report for assessment of functional outcome using Musculoskeletal Tumour Society (MSTS) form.
RESULTS: Plating osteosynthesis with augmented-bone cement was the most common surgical procedure (17 patients) performed followed by arthroplasty (10 patients) and intramedullary nailing (2 patients) There were a total of five complications which were implant failures (2 patients), surgical site infection (2 patients), and site infection mortality (1 patient). The median survival rate was eight months. For the functional outcome, the mean MSTS score was 66%.
CONCLUSION: Patients with skeletal metastasis may have prolonged survival and should undergo skeletal reconstruction to reduce morbidity and improve quality of life. The surgical construct should be stable and outlast the patient to avoid further surgery.
METHODS: This study will include only RCTs published in peer-reviewed journals. A systematic search will be conducted in several electronic databases and other relevant online resources. No limitations are imposed on language or publication date. Participants must be explicitly identified by authors as having OA. Interventions that involved exercise or comparators in any form will be included. Pain is the primary outcome of interest; secondary outcomes will include function and quality of life measures. Quality assessment of studies will be based on the modified Cochrane's risk of bias assessment tool. At least two investigators will be involved throughout all stages of screening and data acquisition. Conflicts will be resolved through discussion. Conventional meta-analysis will be performed based on random effects model and network meta-analysis on a Bayesian model. Subgroup analysis will also be conducted based on study, patient and disease characteristics.
DISCUSSION: This study will provide for the first time comprehensive research evidence for the relative efficacy of different exercise regimens for treatment of OA. We will use network meta-analysis of existing RCT data to answer this question.
SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42016033865.
METHODS: The forward-backward and dual-panel versions of HeartQoL were self-administered among 60 participants who met the inclusion criteria of being a native Bahasa Malaysia-speaking Malay, aged 18 and older, having an indexed diagnosis of ischaemic heart disease and being cognitively fit. The administration sequence of the two versions was randomized. Additionally, three sociolinguists, who were blinded to translation processes and survey findings, rated the translated versions against the source version on three aspects of semantic equivalence.
RESULTS: Textual content in both translated versions was considerably similar (n = 9/14 items, ≈64%). The overall results from weighted kappa, raw agreement, intraclass correlations, and Wilcoxon signed-rank as well as experts' ratings were confirmative of semantic equivalence between the forward-backward and dual-panel versions of the HeartQoL. However, some mixed findings were indicative of potential gaps in both translated versions against the source version.
CONCLUSION: Both the forward-backward and dual-panel methods produced semantically equivalent versions of HeartQoL; but translation alone is insufficient to narrow the subtle gaps caused by differences in culture and linguistic style.
