Menstrual and reproductive factors and risk of pancreatic cancer in women

Background: Pancreatic cancer [PC] is a deadly disease with a 5-year survival of less than 5%. Worldwide PC incidence rates are lower among women than men. While this suggests a protective role for steroid hormones in PC risk, results from epidemiological studies are not consistent

Methods: 153 new incident PC cases and 202 controls were recruited from a prospective case-control study, running in a referral center for endoscopic ultrasonography during 2011-2017. A structured valid and reliable questionnaire was used for data collection by a few trained interviewers. Odds ratios and 95% confidence intervals for reproductive factors and PC were estimated using logistic regression methods

Results: Mean age [SD] of the cases and the controls were 63.18 [11.4] and 63.37 [12.0] years, respectively. Age at menarche, age at menopause, number of parity, gravidity, and abortion were not associated with PC risk

Conclusion: This study does not support the hypothesis that menstrual and reproductive factors are associated with PC risk

Effects of phylloquinone supplementation on lipid profile in women with rheumatoid arthritis: a double blind placebo controlled study

BACKGROUND/OBJECTIVES: Rheumatoid arthritis (RA) is associated with an excess mortality from cardiovascular disease which is likely attributed to an atherogenic lipid profile. Among nutritional factors vitamin K has been recently focused as a pivotal nutrient in improvement of lipid related markers. Thus, this study was designed to determine the effects of vitamin K on lipid profile in this disease. SUBJECTS/METHODS: Fifty eight patients with definitive RA were participated in the present double blind placebo controlled study. They were randomly allocated into two groups to receive vitamin K1 as phylloquinone [10 mg/day] (n = 30) or placebo pills (n = 28), for eight weeks. In order to control the effects of probable confounders dietary intakes, anthropometric measurements including weight and height, clinical status using disease activity score-28 (DAS-28), physical activity and anxiety status were evaluated at baseline. Moreover, serum levels of lipid related markers including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglyceride (TG) were measured at baseline and at the end of intervention. RESULTS: There were no significant differences between the two groups regarding any of the baseline characteristics. After adjusting for some relevant confounders, in comparison between two groups, we observed no significant changes in lipid related markers at the end of intervention. Also, there was no significant difference between before and after intervention values within groups (P > 0.05). CONCLUSIONS: Function of vitamin K1 in lipid profile modification remains still controversial. This study showed that vitamin K1 has no effect on lipid profile in women with rheumatoid arthritis. Further studies with a longer follow-up are required to determine the effects of vitamin K on atherogenic lipid profile.

[ Association between anthropometric indices and disease severity in women with Rheumatoid Arthritis]

Background and Objectives: Rheumatoid arthritis [RA] is an autoimmune disease that inflammatory mediators has an important role in its pathogenesis and leads to bone and joints destruction. This inflammatory status can be effected by different factors such as genetic, dietary intakes and hormonal factors. However, the influence of anthropometric on the severity of RA and inflammatory markers is still debatable

Material and Methods: The current study was done on a group of patients with documented RA who were under regular visit in our university hospital outpatients clinic from the start until the end of 2012. Based on DAS-28 criteria disease activity was assessed by a rheumatology specialist. Anthropometric measurements included body mass index [BMI], Waist to hip ratio [WHR],Waist to Height Ratio [WHtR] all were measured serum levels of highly sensetive cpp IL-6 and MMP-3, were measured in fasting serum samples

Results: There was a Positive correlation between obesity [body mass index and waist to height ratio] and disease activity score and serum levels of hsCRP [P <0.05]. There was no significant correlation between obesity with serum levels of MMP-3 and IL-6 [P > 0.05]

Conclusion: Present study indicates a significant direct correlation between obesity and disease activity and systemic inflammation marker [hscRP]. In RA thus, control of weight could be a very important strategy for maintenance remission in rheumatoid arthritis
