- OBJECTIVE: The objective was to evaluate a manualized theory-driven primary preventive intervention aimed at early childhood obesity. The intervention was embedded in Swedish child health services, starting when eligible children were 9 to 10 months of age and continuing until the children reached age 4. METHODS: Child health care centers in 8 Swedish counties were randomized into intervention and control units and included 1355 families with 1369 infants. Over similar to 39 months, families in the intervention group participated in 1 group session and 8 individual sessions with a nurse trained in motivational interviewing, focusing on healthy food habits and physical activity. Families in the control group received care as usual. Primary outcomes were children's BMI, overweight prevalence, and waist circumference at age 4. Secondary outcomes were children's and mothers' food and physical activity habits and mothers' anthropometrics. Effects were assessed in linear and log-binominal regression models using generalized estimating equations. RESULTS: There were no statistically significant differences in children's BMI (beta = -0.11, 95% confidence interval [CI]: -0.31 to 0.08), waist circumference (beta = -0.48, 95% CI: -0.99 to 0.04), and prevalence of overweight (relative risk = 0.95, 95% CI: 0.69 to 1.32). No significant intervention effects were observed in mothers' anthropometric data or regarding mothers' and children's physical activity habits. There was a small intervention effect in terms of healthier food habits among children and mothers. CONCLUSIONS: There were no significant group differences in children's and mothers' anthropometric data and physical activity habits. There was, however, some evidence suggesting healthier food habits, but this should be interpreted with caution.

- Laminins are widely distributed extracellular matrix proteins. Certain laminin isoforms are predominant in vascular basement membranes and may be critical in maintaining the stability of the mature vessel. On the other hand, formation of new vessels during angiogenesis requires degradation of the basement membrane, exposing the endothelial cells to other laminin isoforms in the surrounding extracellular matrix. We studied the effects of laminin-1 (LN-1) in different in vitro and in vivo models for angiogenesis. LN-1 induced angiogenesis in the chicken chorioallantoic membrane to the same extent as fibroblast growth factor-2 (FGF-2), and vascular development in embryoid bodies was stimulated in a synergistic manner by FGF-2 and LN-1. LN-1 promoted differentiation of endothelial cells in three-dimensional collagen gels, both in the absence and presence of FGF-2. Formation of tubular structures induced by LN-1 was accompanied by increased expression of Jagged-1, a marker of endothelial differentiation, and increased levels of FGF-2 and FGFR-1 transcripts. LN-1 did not regulate signal transduction pathways known to operate down stream of FGF-2. Thus, phosphorylation of ERK was detected in FGF-2- but not in LN-1-treated cells. Taken together, this suggests that laminins may play a fundamental role in angiogenesis by directly affecting gene and protein expression profiles in endothelial cells.

- Following the encouraging report of the Edmonton group, there was a rejuvenation of the islet transplantation field. After that, more pessimistic views spread when long-term results of the clinical outcome were published. A progressive loss of the beta-cell function meant that almost all patients were back on insulin therapy after 5 years. More than 10 years ago, we demonstrated that amyloid deposits rapidly formed in human islets and in mouse islets transgenic for human IAPP when grafted into nude mice. It is, therefore, conceivable to consider amyloid formation as one potential candidate for the long-term failure. The present paper reviews attempts in our laboratories to elucidate the dynamics of and mechanisms behind the formation of amyloid in transplanted islets with special emphasis on the impact of long-term hyperglycemia.
