To assess the intake of artificial food colour additives by 5-14-year-old children in the State of Kuwait, a 24-h dietary recall was conducted twice on 3141 male and female Kuwaiti and non-Kuwaiti children from 58 schools. The determination of colour additives in 344 foods items consumed was performed using high-performance liquid chromatography with diode array detector. A comparison with the Food and Agriculture Organization and World Health Organization acceptable daily intakes (ADIs) was undertaken to evaluate the potential risk associated with the consumption of artificial colour additives by children in Kuwait. The results indicated that out of nine permitted colours, four exceeded their ADIs by factors of 2-8: tartrazine, sunset yellow, carmoisine and allura red. Further, follow-up studies to provide insight into potential adverse health effects associated with the high intakes of these artificial colour additives on the test population are warranted.
Introduction Preservation and restoration of erectile function after radical prostatectomy (RP) for prostate cancer has been extensively studied. However, the influence of RP on the sexual function of female partners is poorly understood. Aim The purpose of this retrospective study is to assess sexuality in men who have undergone RP for prostate cancer and their female partners. Methods Men who underwent RP for localized prostate cancer at our institution from 1996 to 2000 were identified and invited to participate in this study with their female partners. Both partners completed a demographic survey. Men completed the International Index of Erectile Function (IIEF) and female partners completed the Female Sexual Function Index (FSFI) and supplemental questions. Main Outcome Measures Correlation between IIEF and FSFI domain scores was determined in matched couples using Pearson correlation coefficient. Kappa statistics and Spearman correlation coefficient were calculated for supplemental questions and IIEF domain scores. Results Of 1,134 men contacted by letter, 90 (8%) couples completed demographic surveys and both the IIEF/FSFI. Pearson correlation coefficients of IIEF and FSFI domain scores in matched couples demonstrated significant correlation (P < 0.05) of all IIEF domains with all FSFI domains with the exception of male erectile function and overall sexual function with female sexual desire. There was moderate agreement between partner supplemental questions and IIEF domain scores. Conclusions Response rate was very low. FSFI domain scores correlate with IIEF domain scores, indicating an interrelationship between male and female sexual dysfunction in these couples. Evaluation and treatment of sexual dysfunction after RP should involve both partners.
a strong association exists between glycogen storage disease type 1b and inflammatory bowel disease. A high index of suspicion for Crohn disease should be applied in evaluating patients with glycogen storage disease type 1b and intestinal symptoms. These results provide further support for the hypothesis that some forms of inflammatory bowel disease may result from impaired mucosal innate immunity. Additional investigations into the intestinal disease in glycogen storage disease type 1b may be directly relevant to the etiology and treatment of idiopathic Crohn disease.
p53 Mutations 1) are associated with, and likely precede, dysplasia and cancer, 2) are associated with cancer-related mortality, and 3) may possibly be prevented by folic acid supplementation.
Concentrations of polycyclic aromatic hydrocarbons (PAHs) were determined in 115 samples of olive oil (extra virgin olive oil, virgin olive oil, olive oil, pomace olive oil and blended olive oil), cooking oil (corn oil, sunflower oil, sesame oil, palm olein oil, soya oil, canola oil, mustard oil, peanut oil and mixed vegetable oil) and fat (butter and table margarine) collected from retail stores in Kuwait. Carcinogenic benzo[a]pyrene (BaP) was detected in 43% of the samples analyzed. Benz[a]anthracene and chrysene were detected in 37 and 45% of the samples, respectively, that did not contain BaP. Of the individual non-carcinogenic PAHs, naphthalene showed the highest mean concentration (14 microg kg(-1)), while for the carcinogenic PAHs, BaP (0.92 microg kg(-1)) and chrysene (0.87 microg kg(-1)) showed the highest mean values. Approximately 20% of the samples within the olive oil and cooking oil sub-categories exceeded the EU maximum tolerable limit for BaP, with the highest level of 6.77 and 11.1 microg kg(-1), respectively. For the fat sub-category, 9% of the samples exceeded the tolerance limit, with the highest level of 3.67 microg kg(-1). The Kuwaiti general population's dietary exposure to the genotoxic PAHs (PAH8: benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, indeno[1,2,3-cd]pyrene, dibenz[a,h]anthracene and benzo[ghi]perylene) was estimated to be 196 ng day(-1) (3.3 ng kg(-1) bw day(-1), assuming an average adult body weight of 60 kg). Results indicated that PAH8 and BaP(eq) (total sum benzo[a]pyrene equivalents) are more reliable measures of the concentrations of other carcinogenic PAHs in oil and fat samples, while BaP and PAHs alone are not good indicators of the occurrence or degree of contamination by carcinogenic PAHs in these food products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
