Item Pregnancy outcomes following the use of thiocolchicosideOzturk, Z; Olmez, E; Gurpinar, T; Vural, KThiocolchicoside is a commonly used muscle relaxant in orthopedic, rheumatologic or musculoskeletal disorders to treat painful muscle spasms. It is contraindicated in pregnancy and lactation. There is no previously published experience with thiocolchicoside exposure during pregnancy. In this observational study, we collected and evaluated 18 pregnancy outcomes of the women referred to our prenatal consultation service for thiocolchicoside exposure between 2007-2012, and offspring were followed up until 2 years of age. There were 16 live births, 1 spontaneous abortion and 1 elective termination of pregnancy. No major birth defect was observed. The mothers and their babies were free of perinatal complications. No growth or developmental abnormalities were found during follow-up period. Our findings add information on inadvertent use of thiocolchicoside in pregnancy. Further large prospective cohort studies are required to investigate this issue. (C) 2016 Elsevier Inc.

Elevated levels of low-density lipoprotein and total cholesterol are major risk factors for atherosclerotic cardiovascular disease. The aim of this study was to evaluate the effects of the olive leaf extract on serum lipid profile, early changes of atherosclerosis and endothelium-dependent relaxations in cholesterol-fed rats. For this purpose, rats were fed by 2% cholesterol-enriched or standard chow for 8weeks. Some rats in each group were also fed orally by olive leaf extract at doses of 50 or 100mg/kg/day. Atorvastatin at dose of 20mg/kg of body weight daily was also given as positive control. After 8weeks, lipid profiles of rat serums were analyzed. Antioxidant enzyme activities (superoxide dismutase and glutathione peroxidase) and degree of lipid peroxidation (malondialdehyde levels) were also measured in the hearts isolated from rats. In addition, expression of adhesion molecules and endothelium-dependent relaxations of isolated thoracic aortas of rats were evaluated. Total cholesterol and LDL-cholesterol levels were found to be increased in cholesterol-fed rats, and both doses of olive leaf extract and atorvastatin significantly decreased those levels. In conclusion, because the olive leaf extract attenuates the increased cholesterol levels, it may have beneficial effects on atherosclerosis.

The risks associated with prenatal psychotropic drug exposure are often overestimated. It is unclear that psychotropic medication or disorders themselves increase the risk of adverse pregnancy outcomes. The purpose of this study is to generate data about the safety of psychotropic drugs in pregnancy and maternal characteristics of the pregnant women exposed to these drugs. Method: An observational cohort study was performed. Pregnancy outcomes of 135 pregnancies after psychotropic drug exposure are compared to a control group of 275 pregnancies. Results: There were no statistically significant differences in rates of major malformations, miscarriages, and preterm deliveries between the two groups. However, the rate of elective abortions was higher in the exposed group compared to the control group (11.1% vs. 5.1%, respectively; RR 2.18; 95% CI: 1.09-4.39), and most of them were nulliparous (45.2%). The majority of the pregnant women did not smoke cigarettes and no alcohol consumption was reported in both groups. Conclusion: Our study showed that there was a tendency to terminate pregnancy among women exposed to psychotropic drugs. An accurate risk assessment about drug safety and informing pregnant women would help to prevent unnecessary terminations of pregnancies.
