Multidimensional gas-chromatographical analysis of various tensides of natural or synthetic origin in cosmetic products is demonstrated. Comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry allows the qualitative and quantitative determination of alkyl polyglucosides (AG), fatty alcohol ethoxylates (FAEO), fatty alcohol sulfates (FAS), fatty alcohol ether sulfates (FAES) and cocamidopropyl betaines (CAPB) in shower gel and cleaning agents. The samples were aliquoted in two parts. The first part was silylated, diluted and analysed; then, in order to detect anionic tensides (FAES, FAS) too, the second aliquot was hydrolysed before being silylated for analysis. Because of their amphoteric character, the betaines can only be analysed by gas chromatography after thermal decomposition in the injector, which leads to the corresponding amidoamines among other products.

Aim: The aim of this study was to investigate the effect of dietary education on cardiovascular risk factors in patients with rheumatoid arthritis. Method: In this randomized clinical trial, 112 patients with rheumatoid arthritis were randomly assigned into two groups, intervention and control. Dietary education was provided for the intervention group in 4 sessions; anthropometric measurements, serum levels of RF, triglycerides, cholesterol, HDL, LDL, and fasting blood sugar were measured before and three months after intervention. Data was analyzed using SPSS software and appropriate statistical tests. Results: The mean of total cholesterol (p <0.001), triglycerides (p = 0.004), LDL (p <0.001), systolic blood pressure (p = 0.001), diastolic blood pressure (p = 0.003), FBS and BMI (p <0.001) were decreased significantly in the intervention group after education compared the control group. Conclusion: Traditional care for rheumatoid arthritis patients is not enough. Patients need more education in order to improve their situation.

Background: Rheumatoid arthritis (RA) is a chronic and multi-systemic disease with an unknown origin that is associated with inflammation and impairment of the immune system. Cardiovascular disease is the most common cause of death in patients with rheumatoid arthritis. Objectives: This study was conducted to evaluate cardiovascular parameters in patients with rheumatoid arthritis. Methods: In this descriptive study, 112 patients with rheumatoid arthritis, who had been diagnosed for at least six months, were studied. A questionnaire containing demographic data by the researcher using the interview was completed and measuring the cardiovascular parameters was done. Data were analyzed using SPSS software and appropriate statistical tests. Results: Based on the body mass index mean (27.98), the patients under study were overweight; in addition, serum levels of glucose 107.55 ± 38.47, total cholesterol 209.90 ± 37.90, LDL 129.28 ± 30.60 and systolic 145.75 ± 16.23, and diastolic 78.46 ± 11.91, blood pressure in these patients did not have normal distribution. Conclusions: The risk of cardiovascular disorders in patients with rheumatoid arthritis is considerable due to the increase in body mass index, glucose, total cholesterol, LDL, and blood pressure; therefore, screening of at-risk people is recommended.
