- Background: In children with obesity, accentuated insulin secretion has been coupled with development of type 2 diabetes mellitus (T2DM). Bisphenol A (BPA) is a chemical with endocrine- and metabolism-disrupting properties which can be measured in a majority of the population. Exposure to BPA has been associated with the development of metabolic diseases including T2DM.Objective: The aim of this study was to investigate if exposure early in life to an environmentally relevant low dose of BPA causes insulin hypersecretion in rat offspring.Methods: Pregnant Fischer 344 rats were exposed to 0.5 (BPA0.5) or 50 (BPA50) jig BPA/kg BW/day via drinking water from gestational day 3.5 until postnatal day 22. Pancreata from dams and 5- and 52-week-old offspring were procured and islets were isolated by collagenase digestion. Glucose-stimulated insulin secretion and insulin content in the islets were determined by ELISA.Results: Basal (5.5 mM glucose) islet insulin secretion was not affected by BPA exposure. However, stimulated (11 mM glucose) insulin secretion was enhanced by about 50% in islets isolated from BPA0.5-exposed 5- and 52 week-old female and male offspring and by 80% in islets from dams, compared with control. In contrast, the higher dose, BPA50, reduced stimulated insulin secretion by 40% in both 5- and 52-week-old female and male offspring and dams, compared with control.Conclusion: A BPA intake 8 times lower than the European Food Safety Authority's (EFSA's) current tolerable daily intake (TDI) of 4 mu g/kg BW/day of BPA delivered via drinking water during gestation and early development causes islet insulin hypersecretion in rat offspring up to one year after exposure. The effects of BPA exposure on the endocrine pancreas may promote the development of metabolic disease including T2DM.

- Consolation is needed when a human being suffers (i.e. feels alienated from him- or herself, from other people, from the world or from his or her ultimate source of meaning). The aim of this study was to illuminate the meaning of consolation. Tape-recorded narrative interviews were carried out with 18 professionals from various spheres. The transcribed interviews were interpreted hermeneutically. A model of consolation is outlined in a drawing. It states that the mediator and the receiver of consolation must become ready for consolation before it can take place. To be ready means to be present and available. Availability means expressing suffering and listening respectively, and thereby opening up for communion and consoling dialogue. Communion brings about contact with the sacred dimension that human beings share and thus with goodness, light, joy, beauty and life. Consolation involves a shift of perspective and an experience of meaning in spite of suffering.
