RESUMO

The biobased chemical industry is characterised by strong growth. Innovative products and materials such as biopolymers have been developed, and current European demand for biopolymers exceeds the domestic supply. Agroforestry residues can serve as main sources of the basic building blocks for chemicals and materials. This work assesses sustainably available agroforestry residues to feed a high added-value materials and product bioeconomy. To evaluate bioeconomic potential, a structured three-step approach is applied. Cultivation practices, sustainability issues, legislative restrictions, technical limitations and competitive applications are considered. All data regarding bioeconomic potential are processed on a regional level and mapped by ArcGIS. Our results identify wheat straw as the most promising source in the agricultural sector, followed by maize stover, barley straw and rape straw, which all contain a total concentration of lignocellulose of more than 80% of dry matter. In the forestry sector, residue bark from two coniferous species, spruce and pine, is the most promising source, with approximately 70% lignocellulose. Additionally, coniferous bark contains considerable amounts of tannin, which has attracted increasing interest for industrial utilisation. A sensitivity analysis concerning removal rates, residue-to-crop ratios, changes in farming technologies and competing applications is applied at the end of the study to consolidate our results.

RESUMO

OBJECTIVE: Case management (CM) programs are intended to improve care coordination for cancer patients. This quasi-experimental, controlled study evaluated whether such a program was effective in improving health-related quality of life and reducing the psychological distress of breast cancer patients. METHODS: For the study, 126 patients with CM and 118 patients with treatment as usual (TAU) were surveyed at baseline, a 6-month follow-up and a 12-month follow-up. Comparisons of the two groups with regard to quality of life (Short Form-8, European Organization for Research and Treatment of Cancer-11; primary outcome) and psychological distress (Hospital Anxiety and Depression Scale, distress thermometer; secondary outcome) were conducted. RESULTS: Univariate t-tests regarding the primary and secondary outcomes demonstrated improvements in the relevant outcomes at the 6-month and 12-month follow-ups for the intervention group as well as for the control group. An analysis of covariance revealed that the controls showed a higher level of physical quality of life at the 12-month follow-up than the other time points and no differences at 6 months after the baseline. CONCLUSIONS: The tested CM model did not improve the quality of life or psychological well-being of the patients beyond treatment as usual. Possible reasons include that the treatment was already of high standards in the control group or that there are possibly different impacts than found in the literature regarding different forms of organization in CM. The need for and the tailoring of this CM model as well as the transfer of CM to other oncological indications remain to be clarified. Copyright © 2016 John Wiley & Sons, Ltd.

RESUMO

OBJECTIVE: The aim of this study was to investigate fear of disease progression (FoP) during the year following diagnosis of breast cancer and its association with general self-efficacy (SE). METHODS: In a prospective study, 118 breast cancer patients were recruited shortly after diagnosis disclosure (response rate: 54%) and at 1-year follow-up (follow-up rate: 90%). Participants completed self-report measures of general self-efficacy (General Self-Efficacy Scale) and fear of progression (short form of the Fear of Progression Questionnaire). RESULTS: Cross-sectional regression analysis revealed that high FoP is significantly associated with low SE, even when controlling for demographic and medical characteristics (total R² = 0.17). Having children and a relatively short time since diagnosis also significantly predicted higher FoP. Longitudinal analyses showed that FoP decreased significantly over time (p = 0.001; d = 0.25), but a significant decrease was only observed for patients with high initial FoP (p < 0.001; d = 0.74) and not for those with low initial FoP (p = 0.688; d = 0.08). SE was not a significant predictor of FoP at follow-up when controlling for initial FoP and other patient characteristics (incremental R² = 0.001; p = 0.674; total R² = 0.47). Overall, only initial FoP significantly predicted FoP at follow-up (p < 0.001; ß = 0.671). CONCLUSION: Findings that low SE is associated with high FoP can help to improve the treatment of dysfunctional fears in breast cancer patients. As FoP changes only slightly over time, treatment to enhance SE and reduce FoP should be initiated soon after disease disclosure.
