[Validation of food frequency questionnaire to assess folate intake status in breast cancer patients]

Inadequate folate intake could be associated with increased breast cancer risk. The aim of the present study was to assess the folate intake by designed Food Frequency Questionnaire [FFQ] using plasma folate concentration. This analytic cross-sectional study was conducted to evaluate the validity of the semi-quantitative FFQ [136 items] in 152 women with confirmed breast malignancy aged between 35 - 85 years old.. Folate plasma level was assessed by means of automated electrochemiluminescence. The Pearson and partial correlation coefficients were performed between the plasma level of folate and crude, total and energy-adjusted [residual] folate intakes. Area under ROC curve [AUC], sensitivity, specificity, positive and negative predictive values and odds ratio were fulfilled in two models in order to achieve validity assessment. The folate plasma level was significantly correlated with total intake of vegetables, bread and cereal groups [p=0.001] and also with total intake of fruits [p=0.001] and dairy products [p=0.026]. After adjusting for confounders, the folate plasma levels were correlated significantly with daily [beta=0.39], and residual [beta=0.41] folate intake levels [p=0.001]. The area under ROC curves in model I [folate plasma level <5.9 ng/ml] was 0.74 [95%CI=0.63-0.85] and for model II [folate plasma level <10.0 ng/ml] was estimated as 0.61[95%CI= 0.51- 0.71]. Model I indicated more appropriate predictive value [p=0.001] of folate intake assessment via FFQ. The results of this study showed that FFQ described in this study could be a valid and appropriate tool for assessing folate intake status in dietary content of breast cancer patients and also could be representative and valid for assessing the folate rich-food intake status

[Ginger extract reduces delayed gastric emptying and nosocomial pneumonia in ARDS patients hospitalized in ICU]

About 20% of patients who are hospitalized in ICU have ALI/ARDS. Their feeding is usually via enteral nutrition. Delayed gastric emptying [DGE] is a major problem in patients with enteral nutrition, and they are at increased risk for aspiration and subsequent development of pneumonia. The purpose of this study was to evaluate the effect of Ginger extract on DGE and developing nosocomial pneumonia in patients with adult respiratory distress syndrome [ARDS] who are hospitalized in intensive care unit [ICU]. In this double- blind randomized clinicl trial, thirty two ARDS patients, who were on mechanical ventilation and fed via nasogastric tube, were randomly divided two groups. Experimental group [n=16] received ginger extract, and control group [n=16] received coconut oil. The amount of feeding tolerated at the first 48 hours of feeding and within study period, nosocomial pneumonia, number of ICU free days, number of ventilator free days and morality were evaluated during 21 days of intervention. Nosocomial pneumonia was significantly less frequent in the ginger extract group [6.3% in the ginger extract group versus 31.3% in the control group. p= 0.07]. There was no significant difference between two groups in mortality rate. The mean number of ventilator free days was 11.25 +/- 4.73 days in ginger group versus 7.18 +/- 5 days in control group [p=0.02]. The mean number of ICU free days was 4.43 +/- 3.5 days in control group versus 7.06 +/- 3.2 days in ginger group [P=0.04]. This study showed that gastric feed supplementation with ginger extract might reduce DGE and help to reduce the incidence of ventilator associated pneumonia [VAP] in ARDS patients
