Background: Irregular working times or atypical working schedules, accompanied by the risk of unhealthy dietary habits, physical inactivity, and partial sleep deprivation, potentially lead to increased metabolic risk factors. This study aimed to evaluate the nutritional status, physical activity level, and the knowledge, attitude and practice (KAP) of South Zagros Oil and Gas Production Company (SZOGPC) employees (predominantly irregular-shift workers) toward diet and nutrition.Methods: This cross-sectional study was conducted from January to October 2017 on 997 SZOGPC workers. Demographic characteristics, anthropometric measures, biochemical markers, physical activity status, KAP, and dietary intake of the employees were assessed and analyzed. The offered menus were also analyzed.Results: The participants’ mean age was 37.0±6.7 years; the majority of them were married (88.2%) and had irregular-shift work (85.6%). Approximately four-fifths of the participants were either pre-obese or obese, and two-thirds had central obesity. Over half of the participants had high serum triglyceride concentrations and inadequate high-density lipoprotein cholesterol levels. Alkaline phosphatase and alanine transaminase levels were higher than the normal range in 79.0% and 36.2% of the subjects, respectively. The KAP survey showed that only 28-31% of the interviewed participants had acceptable KAP subscale or total scores on the principles related to weight gain and obesity. The mean energy intake was almost 50% more than the average recommendations.Conclusion: Irregular-shift workers appear to be at increased health risk, particularly in terms of acquiring non communicable diseases. Effective lifestyle interventions such as nutrition education and basic menu changes must be considered as a major priority to promote health in such populations.

Background: Although enteral feeding solutions are used to reduce the morbidity and mortality in many malnourished and hospitalized patients, microbial contamination of these products may lead to severe infections, especially in immune suppressed ones. The aim of this study was to evaluate the microbiological quality of commercial enteral feedings in two hospital settings in Shiraz. Methods: Twenty commercial enteral feedings were collected immediately after preparation and then homogenized and serially diluted on the same day. MPN methods were used to evaluate the total viable count and Escherichia coli count. They were also tested for total coliform (pour plate method) and the presence of coagulase positive staphylococci. The results were compared with standard limits. Results: All samples had a total viable count lower than 104 colony forming units (CFU) per g (the maximum recommended level of FDA standard).For all enteral feedings, coliform counts were not detectable (<10 CFU/g).Escherichia coli counts were also lower than those of Brazilian legislation (<3 CFU/g). Coagulase positive staphylococci were recovered just from one sample (5%). Conclusion: Freshly prepared commercial enteral feeding samples h ad a cceptable m icrobial q uality. S uch p roducts are considered to be more acceptable than hospital prepared ones. However, further steps involved in the preparation and administration of commercial feedings can be sources of microbial contamination. Thus implementation of hygienic practices and monitoring procedures during preparation and administration can be suggested.

Background: Diabetes Mellitus (DM) is closely associated with reduction of antioxidant defense system. In the present study, we investigated the antioxidant effect of quercetin supplementation on the glycemic control, lipid profile and oxidative stress indices in patients with type 2diabetes. Methods: Forty seven patients with type 2 diabetes, aged 30-60 years old, were randomly assigned to supplement their daily diet with either an oral quercetin (250 mg/d) or identical placebo (cellulose) capsules for 8 weeks. The supplements were provided to the patients biweekly. Anthropometric data as well as glycemic indices, lipid profile and oxidative stress parameters of blood samples were determined at the baseline and endpoint of the study. Results: Dietary quercetin supplementation significantly improved the total antioxidant capacity (TAC) in the intervention group, when compared to the placebo group (P=0.043). It also resulted in a statistically significant reduction in serum concentration of atherogenic oxidized LDL (ox-LDL) (P0.05). Conclusions: Oral quercetin supplementation was beneficial in improving the antioxidant status of patients with type 2 diabetes while having no other significant effect on glycemic control and lipid profile; however, conducting further studies, using different doses, on the glycemiccontrol and/or hyperlipidemia of thepopulation seems to be valuable.
