Objective To determine how well the functional comorbidity index (FCI) predicts outcomes in older adults with back pain compared to Quan's modification of the Charlson comorbidity index (Quan-Charlson comorbidity index) and the Elixhauser comorbidity index. Design Secondary analysis of a prospective cohort study. Methods We included 5155 adults 65 years of age or older with new primary care visits for back pain. Comorbidity was measured using diagnosis codes 12 months prior to the new visit. Outcomes of functional limitation (Roland-Morris Disability Questionnaire), health-related quality of life (European Quality of Life-5 Dimensions [EQ-5D]), and total health care use (sum of relative value units) were measured 12 months after the new visit. We compared multivariable models containing preselected prognostic factors. Results Spearman correlation coefficients among the indices were 0.70 or greater. Multivariable models for the Roland-Morris Disability Questionnaire had similar R2 and root-mean-square error (RMSE) of prediction when using the FCI (R2 = 0.190; RMSE, 6.19), Quan-Charlson comorbidity index (R2 = 0.185; RMSE, 6.20), or Elixhauser comorbidity index (R2 = 0.189; RMSE, 6.19). Multivariable models for the EQ-5D score showed small differences in R2 and RMSE when using the FCI (R2 = 0.157; RMSE, 0.163), Quan-Charlson comorbidity index (R2 = 0.148; RMSE, 0.164), or Elixhauser comorbidity index (R2 = 0.154; RMSE, 0.163). Multivariable models for health care use had similar Akaike information criterion (AIC) values when using the FCI (AIC = 10.04), Quan-Charlson comorbidity index (AIC = 10.04), or Elixhauser comorbidity index (AIC = 10.01). Conclusion All indices performed similarly in predicting outcomes. There does not seem to be an advantage to using one index over another for older adults with back pain. There is still a need to develop better function-based risk-adjustment models that improve prediction of functional outcomes versus standard comorbidity indices.

ABSTRAK

Bio komposit adalah gabungan suatu bahan yang terdiri lebih dari dua bahan, dan digabungkan membentuk suatu bahan yang mempunyai sifat berbeda dengan bahan aslinya. Dengan melimpahnya serat sagu di Kabupaten Meranti, hal ini tentu dapat dimanfaatkan terutama di bagian kulit sagu yang sering dibuang dan menyebabkan limbah. Sehingga kulit ini dapat dipakai untuk pembuatan komposit, dengan menggabungkan serat kulit pohon sagu dengan resin polyester. Untuk mengetahui sifat mekanik maka diperlukan pengujian komposit terhadap kekuatan bending dan ketangguhan impact. Dengan variasi volume 80% resin + 20% serat, 70% resin + 30% serat dan 60% resin + 40% serat. Dengan harapan untuk mendapatkan komposisi yang tepat, dan meningkatkan kegunaan dari limbah pohon sagu, untuk menjadi material yang baru. Tahapan ini dimulai dengan pemilihan serat, dan pencampuran resin polyester. Pembuatan spesimen dan prosedur pengujian mengacu pada, ASTM D790 untuk Bending dan ASTM D6110 untuk Impact. Hasil dari pengujian impact dan bending menunjukan kekuatan dari uji bending terbesar adalah 22,39 N/mm2, untuk fraksi volume 60% resin + 40% serat. Sedangkan kekuatan terendah untuk uji bending adalah 8,85 N/mm2, untuk fraksi volume 80% + 20%. Dan ketangguhan impact terbesar adalah 47,173 J untuk fraksi volume 60% resin + 40% serat, sedangkan kekuatan impact terendah adalah 37,674 J, untuk fraksi volume 80% resin + 20% serat. Dapat disimpulkan jika di spesimen fraksi seratnya besar, maka akan memiliki kekuatan dan ketangguhan spesimen yang lebih baik.

Published: March 2020

In this work, the properties of the composite produced from waste carton with various tiger nut fibre contents having cassava starch slurry as binder were investigated. The results obtained showed the ranges of the mean thermal conductivity, bulk density, specific heat capacity, thermal diffusivity, thermal absorptivity, nailability, flexural strength and compressive strength values to be (0.0447 – 0.0603) Wm-1K-1, (683.62 – 746.32) kgm-3, (1439.811 – 1840.554) J/kg/K, (5.612 - 3.553) 10-8 m2s-1, (25.456 – 31.993) m-1, (23.9 – 100)%, (1.58 – 1.86) MPa and (2.16 – 2.78) MPa respectively between 8.3% and 43.1% of the fibre content. It was generally observed that with a choice variation in the fibre content, the performance of the developed board can be optimized for structural applications. Hence, instead of discarding the fibre as waste, recycling it can help to provide raw material for the production of cost effective and environmentally friendly materials. This will in turn reduce health risk caused by environmental pollution due to improper waste disposal practice of such material.
