Maternal paraben exposure triggers childhood overweight development.

Parabens are preservatives widely used in consumer products including cosmetics and food. Whether low-dose paraben exposure may cause adverse health effects has been discussed controversially in recent years. Here we investigate the effect of prenatal paraben exposure on childhood overweight by combining epidemiological data from a mother-child cohort with experimental approaches. Mothers reporting the use of paraben-containing cosmetic products have elevated urinary paraben concentrations. For butyl paraben (BuP) a positive association is observed to overweight within the first eight years of life with a stronger trend in girls. Consistently, maternal BuP exposure of mice induces a higher food intake and weight gain in female offspring. The effect is accompanied by an epigenetic modification in the neuronal Pro-opiomelanocortin (POMC) enhancer 1 leading to a reduced hypothalamic POMC expression. Here we report that maternal paraben exposure may contribute to childhood overweight development by altered POMC-mediated neuronal appetite regulation.

Long-term surveillance of biologic therapies in systemic-onset juvenile idiopathic arthritis: data from the German BIKER registry.

OBJECTIVE: Using data from the German Biologics JIA Registry (BIKER), long-term safety of biologics for systemic-onset JIA with regard to adverse events of special interest was assessed. METHODS: Safety assessments were based on adverse event reports after first dose through 90 days after last dose. Rates of adverse event, serious adverse event and 25 predefined adverse events of special interest were analysed. Incidence rates were compared for each biologic against all other biologics combined applying a mixed-effect Poisson model. RESULTS: Of 260 systemic-onset JIA patients in this analysis, 151 patients received etanercept, 109 tocilizumab, 71 anakinra and 51 canakinumab. Patients with etanercept had higher clinical Juvenile Arthritis Disease Activity Score 10 scores, active joint counts and steroid use at therapy start. Serious adverse events were reported with higher frequency in patients receiving canakinumab [20/100 patient years (PY)] and tocilizumab (21/100 PY). Cytopenia and hepatic events occurred with a higher frequency with tocilizumab and canakinumab. Medically important infections were seen more often in patients with IL-6 or IL-1 inhibition. Macrophage activation syndrome occurred in all cohorts with a higher frequency in patients with canakinumab (3.2/100 PY) and tocilizumab (2.5/100 PY) vs anakinra (0.83/100 PY) and etanercept (0.5/100 PY). After adjustment only an elevated risk for infections in anakinra-treated patients remained significant. Three definite malignancies were reported in patients ever exposed to biologics. Two deaths occurred in patients treated with etanercept. CONCLUSION: Surveillance of pharmacotherapy as provided by BIKER is an import approach especially for patients on long-term treatment. Overall, tolerance was acceptable. Differences between several biologics were noted and should be considered in daily patient care.

Assessment of maternal drug intake by urinary bio monitoring during pregnancy and postpartally until the third perinatal year.

PURPOSE: Although sales of prescribed and over-the-counter (OTC) medication are rising, little is known about individual drug intake. This study was aimed to obtain complementary information about drug intake. METHOD: Information on drug utilization was obtained in a female cohort for five different time points (TP): 36th week of pregnancy (n = 622), 7th perinatal week (n = 533), 3rd perinatal month (n = 340), and 1st perinatal (n = 534) and 3rd perinatal year (n = 324) by a validated urine screening method. RESULTS: Drugs were detected 807 times among all analyzed samples (n = 2353) with less drug intake for early TP compared with later TP (~24.4%, n = 152; ~33.8%, n = 180; ~23.2%, n = 79; ~42.5%, n = 227; and ~52.2%, n = 169). The diversity of drugs increased from 25 up to 40 different drugs for the investigated period. OTC drugs were detected most frequently reflected by the top three drugs: acetaminophen (~37%, n = 292), ibuprofen (~23%, n = 183), and xylometazoline (~12%, n = 98). Mainly guideline-orientated drug therapy was observed. However, contraindicated ibuprofen intake during third trimester urine samples (n = 26) and a repeated usage of acetaminophen and/or ibuprofen (n = 9), as well as xylometazoline (n = 7), reveal missing information about drug safety. CONCLUSION: Bio monitoring was applied for detection of drug intake revealing a lack of information about OTC products and their health risks. Hence, information about health risks for certain drugs and patient groups must be improved for and by pharmacists, to avoid (i) usage of contraindicated drugs and (ii) abuse of OTC drugs.

Regional and socio-economic differences in food, nutrient and supplement intake in school-age children in Germany: results from the GINIplus and the LISAplus studies.

OBJECTIVE: To describe regional differences between eastern and western Germany with regard to food, nutrient and supplement intake in 9-12-year-old children, and analyse its association with parental education and equivalent income. DESIGN: Data were obtained from the 10-year follow-up of the two prospective birth cohort studies - GINIplus and LISAplus. Data on food consumption and supplement intake were collected using an FFQ, which had been designed for the specific study population. Information on parental educational level and equivalent income was derived from questionnaires. Logistic regression modelling was used to analyse the effect of parental education, equivalent income and region on food intake, after adjusting for potential confounders. SETTING: Germany. SUBJECTS: A total of 3435 children aged 9-12 years. RESULTS: Substantial regional differences in food intake were observed between eastern and western Germany. Intakes of bread, butter, eggs, pasta, vegetables/salad and fruit showed a significant direct relationship with the level of parental education after adjusting for potential confounders, whereas intakes of margarine, meat products, pizza, desserts and soft drinks were inversely associated with parental education. Equivalent income had a weaker influence on the child's food intake. CONCLUSIONS: Nutritional education programmes for school-age children should therefore account for regional differences and parental education.

Osteoporosis in juvenile idiopathic arthritis--a practical approach to diagnosis and therapy.

In all subgroups of juvenile idiopathic arthritis, a decrease in bone mass has been described in a high percentage of children. Recently, new pathogenetic concepts have identified muscle mass as the strongest predictor of bone mass and bone is now recognized as part of the musculoskeletal system. In addition, the sophisticated use of bone densitometry in pediatrics, including new measurement techniques, has provided the tools for a reliable assessment. A standardized diagnostic approach to the musculoskeletal system, including prophylaxis and therapy, is, therefore, mandatory in all children with JIA who do not achieve rapid remission. In this review, diagnostic and therapeutic options are being described and possibilities to incorporate them into clinical practice are suggested.
