Combining garden therapy and supported employment - a method for preparing women on long-term sick leave for working life.

Women are overrepresented among the group people suffering from long-term illness. In addition to their illness, suffering long-term sick leave leads to economical restraints as well social distress. There are gaps in our understanding of the challenges these women face. There is also lack of knowledge about how these challenges can be effectively addressed in rehabilitation. This deficiency is problematic from an ethical, justice and a caring perspective. In this study, changes in health-related quality of life (HRQoL) among women on long-term sick leave were investigated during and after participating in a rehabilitation programme combining two validated methods, Garden Therapy and Supported Employment (SE). The study also discusses difficulties in realising research related to vulnerable under-privileged people. From a population of 329 women who had reported their interest to participate, 245 were randomised to the programme. Of these 144 accepted participation in the research project and of these 123 women accepted to answer the SF-36 questionnaire. The participants were between 21 and 62 years with poor physical and mental health. They had received public financial support from <1 year to >10 years. The SF-36 measurement was carried out at baseline, after completion of Garden Therapy and after completion of SE. The results are based on data of respondents who participated at all the three occasions (n = 52). When comparing HRQoL baseline with the following occasions, the participants' General Health (GH), Vitality (VT), Social Functioning (SF) and mental health had improved significantly. The Four Leaf Clover (FLC) programme could be an appropriate method for reducing socially induced suffering. However, to conduct intervention studies where vulnerable persons are involved, it is off vital importance to consider whether the participants have the strength to complete the intervention.

Microbial bromate reduction following ozonation of bromide-rich wastewater in coastal areas.

Ozonation of wastewater can reduce the release of organic micropollutants, but may result in the formation of undesirable by-products, such as bromate from bromide. Bromide is one of the most abundant ions in seawater, the primary precursor of bromate during ozonation, and the end product in microbial bromate reduction. Investigations were carried out to compare the concentration of bromide in wastewater in coastal and non-coastal catchment areas, to monitor bromate formation during ozonation, and to assess the potential for subsequent bromate reduction with denitrifying carriers. Higher bromide concentrations were systematically observed in wastewater from coastal catchment areas (0.2-2 mg Br-/L) than in wastewater from non-coastal areas (0.06-0.2 mg Br-/L), resulting in elevated formation of bromate during ozonation. Subsequent investigations of bromate reduction in contact with denitrifying carriers from two full-scale moving bed biofilm reactors (MBBRs) showed that 80 % of the bromate formed during ozonation could be reduced to bromide in 60 min with first-order rate constants of 0.3-0.8 L/(gbiomass·h). Flow-through experiments with denitrifying carriers also showed that combined reduction of bromate and nitrate could be achieved below a concentration of 2 mg NOx--N/L. These findings indicate that bromide-rich wastewater is more likely to be of concern when using ozonation in coastal than in non-coastal areas, and that bromate and nitrate reduction can be combined in a single biofilm reactor.
