- Objective. The aim of the present study was to examine the impact of general diseases and medication on oral health-related quality of life (OHRQoL) in a Swedish adult population using the Swedish version of Oral Impacts on Daily Performances (OIDP). Material and methods. A three-site sample of 200 adults (20-86 years; participation rate 70%) was interviewed using the OIDP, and a medical anamnesis was performed in 2006-7. A self-reported questionnaire provided complementary socio-economic data. Results. The burden of medical diagnoses and medications was greatest among the older participants in the study. The mean number of medicines in regular users was: ≥60 years, 3.6 (SD 2.6); 40-59 years, 1.9 (SD 1.5); and 20-40 years, 1.9 (SD 1.8) (p =0.013). There were no gender differences in general health or medication variables. Self-reported health, medical diagnoses and medication were significantly and consistently associated with the OIDP score: subjects with ≥1 diagnosis, OR 2.22 (95% CI 1.19-4.14) and subjects with ≥1 medicines, OR 1.85 (95% CI 1.01-3.40) versus those without diagnoses or medication. However, there was a clear gradient: OIDP scores increased with increasing numbers of diagnoses and medicines. Conclusion. The Swedish version of the OIDP was found useful for measuring impacts of general health and medication on OHRQoL. Dental care should pay special attention to patients with medical conditions or who are on medication, because these patients are more likely to experience oral impacts on daily performances.

Accelerated biodegradation of n-alkanes in aqueous solution by the addition of fermented whey

Journal article (peer-reviewed)abstract
- The effect of fermented whey on the aerobic degradation of n-alkanes by a microbial consortium was investigated in an aqueous system. Microbial degradation of 100 mg n-alkanes (C12, C14, C16 and C18) in mineral nutrient medium was assessed by measuring the decrease in n-alkanes, production of CO2 and increase in biomass. The addition of fermented whey at a concentration of 5 mg dry weight to a nutrient medium receiving a small-sized inoculum (103.4 CFU ml-1)shortened the lag phase from 8 to 3 days, but the degradation rate during the degradation phase was not enhanced. The shortened lag phase at low initial concentration of microorganisms indicates that the fermented whey stimulates growth in the initial phase, without reducing the consortium's capacity for n-alkane degradation.
