Realist Approach to Social Policies (RASP) study to reduce socioeconomic health inequalities through systems change: protocol for a research project combining mixed-methods realist research with institutional action research.

Introduction: Health inequalities are rooted in inequality in vital resources for health, including financial resources, a supportive informal network, a stable living situation, work or daytime activities or education and literacy. About 25% of Dutch citizens experience deprivation of such resources. Social policy consists of crucial instruments for improving resources in those groups but can also have adverse effects and lead to additional burdens.

Flourishing mental health and lifestyle behaviours in adults with Type 1 and Type 2 Diabetes Mellitus: results from the Diabetes MILES - The Netherlands Study.

Objective: To examine the associations between mental health and lifestyle in adults with type 1 and type 2 diabetes mellitus (T1DM and T2DM).

Methods: Online survey data from the cross-sectional Diabetes MILES - The Netherlands Study was analysed, including 270 adults with T1DM and 325 with T2DM. Mental health status (flourishing, moderate and languishing) in relation to diet, physical activity, alcohol consumption and smoking was analysed with ANCOVA and logistic regressions (adjusted for confounders).

Long-chain vitamin K2 production in Lactococcus lactis is influenced by temperature, carbon source, aeration and mode of energy metabolism.

Background: Vitamin K2 (menaquinone, MK-n) is a lipid-soluble vitamin that functions as a carboxylase co-factor for maturation of proteins involved in many vital physiological processes in humans. Notably, long-chain vitamin K2 is produced by bacteria, including some species and strains belonging to the group of lactic acid bacteria (LAB) that play important roles in food fermentation processes. This study was performed to gain insights into the natural long-chain vitamin K2 production capacity of LAB and the factors influencing vitamin K2 production during cultivation, providing a basis for biotechnological production of vitamin K2 and in situ fortification of this vitamin in food products.

Possible contamination with clenbuterol from treated veal calves to untreated pen mates.

To investigate whether clenbuterol-treated calves could contaminate untreated pen mates, three animal experiments were performed. (1) One calf of a pen of five was treated with clenbuterol by injection (Ventipulmin injection, REG NL 2532, 2.5 mL/100 kg) twice a day for 10 days.

Illegal treatment of barrows with nandrolone ester: effect on growth, histology and residue levels in urine and hair.

The effect of 17β-19-nortestosterone (17βNT) treatment of barrows on residue levels and growth was evaluated. Five barrows were treated three times during the fattening period with 17βNT phenylpropionate (Nandrosol, nandrolone phenylpropionate 50 mg/ml,1 mg/kg body weight). Another five barrows were untreated and five boars (untreated) were kept as positive control.
