ABSTRACT
Background: Atherosclerosis and subsequent coronary artery disease is the leading cause of death in Iranian population. High serum lipid levels, especially the elevated level of low-density lipoprotein [LDL], have been shown to be strongly related to the development of atherosclerosis. The relationship between dietary glycemic index [GI] and lipid profile, particularly in nonwestern populations, has not been well studied; also, the result of studies are inconsistent. The aim of this study was to evaluate the relationship between dietary glycemic index [GI] and main risk factor of atherosclerosis including abnormal blood lipid levels in healthy women
Methods: This cross-sectional study was done to investigate the associations between dietary GI and lipid profile. The subjects were 87 female personnel of Ahvaz Jundishapur University of Medical Sciences aged 25-55 y; they were recruited randomly. Dietary GI was calculated from six 24 hour recalls [including 4 usual days and 2 holidays]
Results: The mean of dietary GI was 72.1+/-4.07. After adjustment for potential dietary and non- dietary confounding factors, no significant relationship was found between dietary GI with HDL-C and LDL-C. There was also no statistically significant relationship between GI and total cholesterol or fasting Triacylglycerol
Conclusion: Findings of this study did not support the hypothesis of physiologic relevance of GI and lipid profile abnormality as a potential risk factor for atherosclerosis
ABSTRACT
To determine the frequency of Nosocomial Infections [NI] presenting during the in-patient stay and their causative bacteria in Golestan teaching hospital, Iran. In a prospective cross-sectional study, all patients admitted in Golestan teaching hospital of Ahvaz from Sep 2009 to March 2010 were included in the study. NNIS questionnaire was used for data collection and essential cultures were done. From 9407 hospitalized patients, 296 cases [3.1%] proved to have NI. They consisted of 118 women [39.9%] and 178 men [60.1%] [Mean age 46.1 +/- 24.1]. The rate of NI in Intensive Care Units [ICU wards] was 12% and in other wards was 1% [P=0.003]. The mortality rate among patients with NI was 23.3%. The most common types of infection were: UTI [43.6%], pneumonia [35.1%], surgical wound infection [14.5%] and blood infection [6.8%]. The most common infection in ICU was pneumonia [45%] and in other wards was UTI [P=0.001]. The most common causative bacteria were enterobacter [59.8%] followed by Escherichia coli [34.5%] and pseudomonas aeroginosa [25.3%]. Nosocomial Infections [NI] rate in our study was low compared to many centers and significantly higher in ICU than other wards. Gram negative bacteria were the most common cause of Nosocomial Infections [NI]
ABSTRACT
Infection is one of the most common causes of complication in bum patients. A severe burn injury is not only a life-threatening problem for the burned patients, but it also may have serious financial effects on the patient and society. In a descriptive study, medical files of 6082 consecutive admissions for burn injury treated at Taleghani Burn Hospital over a five-year period were reviewed. The mean age of patients was 22.4 +/- 16.9 years and overall male to female ratio was 1.25. Burns were more common during winter [33.6%] [p<0.001]. Fire accident was the most common cause in all age groups [66.1%], except subjects aged less than 10 years. The percent of TBSA for burned patients ranged between 1% and 100% with a mean of 38.7 +/- 29.8%. There was a correlation between TBSA percentage and age [r=0.18%]. The mean and median hospital stay was 14 and 9 days, respectively, with a range of 1-311 days. There was a significant association between fire accident and hospital stay [p<0.001]. Of 6082 patients, 486 deaths were recorded [8%]. E. colt in urine culture and Pseudomonas aeruginosa in blood and wound culture were the most predominant isolated bacteria. Preventive programs for reducing the risk of burns are needed. Furthermore, high percentage of TBSA and mortality and the presence of multi-drugs resistance bacteria are major concerns in our hospital

To compare the hemostatic effect of sulfur hexafluoride 20% [SF6 20%] with lactated Ringer's solution for prevention of early postoperative vitreous hemorrhage following diabetic vitrectomy. In a prospective randomized clinical trial, 50 eyes undergoing diabetic vitrectomy were divided into two groups. At the conclusion of surgery, in one group the vitreous cavity was filled with SF6 20% while in the other group lactated Ringer's solution was retained in the vitreous cavity. The two groups were compared for the rate of early postoperative vitreous hemorrhage. The incidence of vitreous hemorrhage was lower in the SF6 group than the Ringer's group 4 days [20% vs. 68%, P=0.001], 7 days [24% vs. 60%, O=0.01] and 4 weeks [16% vs. 40%, P=0.059] after vitrectomy. In comparison with lactated ringer's solution, SF6 20% had a significant hemostatic effect especially in the early postoperative period after diabetic vitrectomy and reduced the incidence of vitreous hemorrhage
