ABSTRACT
The patients with Post-Infectious Irritable bowel syndrome [PI-IBS], a subtype of irritable bowel syndrome, suffer from bacterial gastroenteritis. Since Campylobacter Jejuni [C] is one of the most common agents in this syndrome, we aimed to evaluate the prevalence of Campylobacter Jejuni in patients with Irritable Bowel Disease. This case - control study was conducted on 160 patients divided into 2 equal groups of healthy and unhealthy. The presence of Anti- CJ antibody [IgG and IgA] was evaluated by ELISA and the comparison was performed by chi-square test, The mean age of case [31.51] and control [31.84] was not statistically different [P = 0.87]. Titer of Anti- Campylobacter Jejuni antibody IgG was positive in 25% of patients and 18.8% of the healthy ones [p=0.02]. IgA Seropositivity in patients was 7.5% but no one in control group was positive [p =0.01]. The Seroprevalence of CJ in patients with IBS was higher significantly than that of control group. Thus, CJ can be known as one of the causes of Post-infection in patients with IBS in our region and it should be paid more attention in diagnostic assessment of these patients
ABSTRACT
Bioelectrical impedance analysis [BIA] is a simple and noninvasive body composition analysis technique. The aim of this study was to assess the body composition and its trend of changes in adult cancer patients referred to Tehran Rasol-e-Akram and Firoozgar Hospitals for chemotherapy. In this cross-sectional study, 71 patients [41 men and 30 women, 51.9 +/- 15.4 years old] with different types of malignancies were selected from the 2 hospitals by stratified sampling. Body composition was determined by the BIA technique at the beginning, in the middle, and at the end of the chemotherapy treatment period. Data were analyzed by repeated measure ANOVA and Wilcoxon tests, using the SPSS12 software. Nonsignificant changes were observed in the mean weight, fat-free mass, fat mass, dry fat-free mass and total body water of the 50 patients who successfully completed the treatment [average of 5 months]. Twenty-one patients died during the treatment cycles [average of 2.5 months]. They had a significant decreasing trend for weight, fat mass and dry fat-free mass [P= 0.01, P= 0.02, and P= 0.01, respectively] they had a higher reduction of fat mass than fat-free mass [2 +/- 3.8 kg and 0.7 +/- 1.9 kg respectively]. Weight reduction of the cancer patients who died during the study was due to both fat mass and dry fat-free mass reductions, while in the patients who successfully completed the treatment no significant changes in body weight or body compositions were observed. It can be concluded that weight loss due to reductions in fat mass and dry fat-free mass in cancer patients during chemotherapy may result in their decreased survival

The most important goal of IBTO is to prepare safe and sufficient blood and blood components; thus, the appropriate screening of donors out of low-risk population is significant. It is likely that women population compared with men is at lower risk in regard to high-risk behaviors leading to blood-transmitted infections. However, the donation attempts on part of women compared to men are less frequent. A cross-sectional study was conducted on Iranian female population at the age range of 17-65 in eight provinces of Iran. A questionnaire was prepared. The number of samples was calculated as 12000 using statistical formulas. The sampling method was multi-stage cluster. Finally, the data were analyzed using SPSS 11 statistical software. The age average of women under study was 32.6 +/- 12.1. Most of them were married, housekeeper, and had diploma. 24.1% of them had a record of blood donation while 75.4% never enjoyed such an experience. The educational background and employment rate of women with no blood donation precedent were significantly lower than those with previous history of blood donation [P
