Abstract STUDY QUESTION What self-management factors are associated with quality of life among women with endometriosis? SUMMARY ANSWER Greater self-efficacy was associated with improved physical and mental quality of life. WHAT IS KNOWN ALREADY Women with endometriosis have an impaired quality of life compared to the general female population. However, most studies have investigated quality of life in a hospital or clinic setting rather than a community setting and the association between self-management factors and quality of life have not, to date, been investigated. STUDY DESIGN, SIZE, DURATION A cross-sectional, population-based online survey was performed, which was advertised through women’s, community and endometriosis-specific groups. PARTICIPANTS/MATERIALS, SETTING, METHODS A total of 620 women completed the survey for this study. Mental and physical quality of life was assessed using the standardized SF36v2 questionnaire. Self-management factors included self-efficacy, partners in health (active involvement in managing the condition) and performance of self-care activities. Treatment approaches included the use of hormonal treatment, pain medications and complementary therapies and whether the participant had a chronic disease management plan. Hierarchical regression analyses were used to examine whether self-management and treatment factors were associated with quality of life. MAIN RESULTS AND THE ROLE OF CHANCE Both physical and mental quality of life were significantly lower among women with endometriosis compared to the mean scores of the general Australian female population (P < 0.001). Physical quality of life was positively associated with income sufficiency (P < 0.001) and greater self-efficacy (P < 0.001), but negatively associated with age (P < 0.001), pain severity (P < 0.001), use of prescription medications (P < 0.001), having a chronic disease management plan (P < 0.05) and number of self-care activities (P < 0.05). Mental quality of life was positively associated with being older (P < 0.001), partnered (P < 0.001), having a university education (P < 0.05), increasing self-efficacy (P < 0.001) and higher partners in health scores (P < 0.001). LIMITATIONS, REASONS FOR CAUTION Results are derived from a cross-sectional study and can only be interpreted as associations not as causal relationships. The sample was more educated, more likely to speak English and be born in Australia than the general Australian female population of the same age, which may influence the generalizability of these results. WIDER IMPLICATIONS OF THE FINDINGS This study investigated a knowledge gap by investigating quality of life of women with endometriosis in a large community sample. Self-efficacy was significantly associated with both physical and mental quality of life. Supporting women with endometriosis to improve self-efficacy through a structured chronic disease management programme may lead to improvements in this aspect of wellbeing.

Wood Residues

Intensive potato cropping has been reported as a major cause of degradation of sandy soils. Wood residues from tree clipping applied to soils can substitute for crop residues to maintain adequate organic matter levels and crop productivity. However, this ligneous material presents a C:N ratio varying from 50 to 175 and, when applied in large quantities, may induce N immobilization at the expense of the crop. The objectives of this study were to quantify the importance of this N immobilization following addition of residues and its effect on yield and quality of potato crops. Fresh or humified residues (50 t ha−1) were applied to the soil and incorporated. The third treatment received no residue. Each treatment was subdivided into subtreatments which received either 0, 150, 200 or 250 kg N ha−1. P, K, Mg and S were applied at the same rate on all treatments. Following the application of wood residues in 1987, 46 kg N ha−1 were immobilized in amended plots. N recovery from fertilizer was 51%. To obtain comparable yields of similar quality to those measured on unamended plots, an additional 1.9 kg N t−1 residues added or 100 kg N ha−1 were required. In 1988, N immobilization was considerably reduced; yield and quality of potato tubers in plots that received wood residues the previous year were comparable to those of the unamended plots with appropriate fertilization. Water retention was significantly improved in plots that received wood residues. Partial decomposition of the residues for 1 yr prior to application on the soil did not significantly improve plant growth compared to fresh residues.

The use of charcoal (CC) for various industries was analysed; the modern ideas about the factors influencing the process of obtaining CC were considered. The effect of raw materials nature (wood or agricultural wastes) and their characteristics (size, physical properties, chemical composition), as well as carbonization temperature, heating rate, oxygen level and pressure on the yield and quality of CC was described. The existing technologies for charcoal production were analyzed; they were classified according to the type of heating initiation and temperature maintenance during the carbonization process. The Lambiotte, DPC and Carbonex technologies were considered.
