The Relationship of Adherence to the Mediterranean Diet with Disease Activity and Quality of Life in Crohn's Disease Patients.

Background and Objectives: Emerging evidence is placing the Mediterranean diet (MD) in the spotlight as a potential dietary model that could benefit inflammatory bowel disease (IBD) patients in terms of prevention and progress of the disease. The main aim of the present study is to shed some light on the relationship between the adherence to the MD and the degree of disease activity, as well as the quality of life in patients with Crohn's disease (CD). Materials and Methods: An administered questionnaire was used to assess and record a number of parameters, including recent medical and weight history, anthropometric characteristics, disease activity (in remission or active disease), and quality of life of both male and female CD patients. Moreover, the level of compliance of the participants to the Mediterranean diet model was evaluated and its relationship with disease activity and quality of life was investigated. Results: Adherence to the MD was significantly higher in patients with inactive disease than in those with active disease (p = 0.019). According to the correlation analysis conducted, adherence to the MD was negatively correlated with disease activity (p = 0.039) and positively correlated with quality of life (QoL) (p = 0.046) of the participants. Intake of fruits, vegetables, and dairy products was significantly higher in remission patients (p = 0.046, p = 0.001, p = 0.041, respectively). Conclusions: We conclude, according to the findings of the study, that adherence to the MD is associated with disease activity and QoL in patients with CD. Future research should focus on MD intervention studies on IBD patients in order to assess its effect on modulating disease activity/course and related inflammatory biomarkers.

The Effect of Shift Working on Dietary Patterns of Healthcare Practitioners during the COVID-19 Pandemic: A Cross-Sectional Study.

Background and Objectives: Health professionals' working schedules often do not allow them to follow a balanced way of life, and the nature of their work can affect their weight and eating habits. The aim of the present study is to shed some light on the impact of night shift working on the dietary practices of healthcare practitioners in Greece. Materials and Methods: This was a cross-sectional study. With the use of an administered questionnaire several parameters were assessed, including anthropometric characteristics, weight history, as well as nutritional habits of the same group of participants during night shifts and when at regular working hours. Moreover, nutritional beliefs of the subjects were recorded, as well as the level of adherence to the Mediterranean diet. Results: It was observed that in all food groups, including water, used to compare the nutritional patterns of the participants during night shifts and when working regular hours, statistical differences were noted (p = 0.001). Furthermore, the participants who reported a higher adherence to the Mediterranean diet and self-reported healthier nutritional habits, had a statistically lower weight compared to the participants that rarely followed the specific model or reported unhealthier eating routine (p = 0.010 and p = 0.015, respectively). Conclusions: We conclude that shift-working healthcare professionals are associated with disturbed eating behaviours leading to the high consumption of unhealthy food. The implementation of interventions that will concentrate on educating health workers on balanced nutrition and improving physical environment (i.e., food availability, healthier food choices) seems to be of great importance.

The Effect of Fat Supplementation on the Appearance of Symptoms Associated With Dumping Syndrome in Patients Having Undergone Gastric Surgery: Preliminary Results.

BACKGROUND/OBJECTIVES: Data on the effect of dietary fat on dumping syndrome (DS) symptoms are limited. The aim of this study was to assess the effect of the addition of fat to a carbohydrate meal on the appearance of DS symptoms and glycemic response, in patients who had undergone gastric surgery. SUBJECTS/METHODS: This was an interventional crossover study. Patients scheduled for gastric surgical procedures related to DS at two surgical units of two public hospitals (General University Hospital of Larissa and General Hospital of Larissa) were considered for study inclusion. Patients presenting symptoms suggestive of diagnosis (n = 12), after the ingestion of a carbohydrate meal, were used as both intervention and control groups. During the intervention process, a fat supplement was added to the carbohydrate meal that was previously used for diagnosis. Glycemic response and the amount and intensity of DS symptoms provoked by the two meals were assessed at both appointments. RESULTS: Blood glucose levels were significantly lower in the group that consumed the added fat meal compared with the group that consumed the carbohydrate meal 60 minutes after ingestion (p = 0.028). Furthermore, a significant reduction was noted in the amount of late dumping symptoms (p = 0.021) and the intensity of both early and late dumping symptoms (p = 0.007 and p = 0.012 respectively), after fat addition.  Conclusions: Incorporating fat into a carbohydrate meal seems to attenuate postprandial blood glucose rises and reduce the amount and intensity of DS symptoms, in patients who had undergone gastric surgery.

Preliminary Results on the Comparative Evaluation of Alkaline Phosphatase Commercial Tests Efficiency in Non-Cow Milk Pasteurization.

The demand for non-cow milk and the products derived from it, is constantly increasing; thus, correct and effective pasteurization becomes necessary. Typical practices for evaluating milk pasteurization are mainly based on the thermal inactivation of an endogenous enzyme, alkaline phosphatase (ALP). The ALP tests, originally designed and applied to pasteurized cow milk, are often used to control pasteurization in non-cow milk, without sufficient data on their suitability; EFSA calls on the scientific world for collecting more information on the subject. In this study, the pertinent details of the ALP assay for non-cow milk products are summarized, and a comparison is performed regarding the evaluation of the adequacy of commercially available tests for the determination of ALP activity in non-cow milk. At the same time, raw and pasteurized non-cow milk was analyzed microbiologically using standard ISO methods and MALDI-TOF MS in order to confirm the thermal effect on common microorganisms. In these preliminary results, various ALP tests do not appear to be fully reliable as indicators for the pasteurization of some types of non-cow milk such as camel and donkey milk or even goat and sheep milk, using the EFSA proposed limits. ALP commercial kits may not be suitable as pasteurization indicators for various types on non-cow milk, and alternatives should be investigated.

Exposure assessment on aflatoxin M1 from milk and dairy products-relation to public health.

BACKGROUND-AIM: Aflatoxin M1 (AFM1) contaminates milk and dairy products that are widely consumed foods. Therefore, there is increased concern for human exposure to the toxic action and the negative health effects that AFM1 presents. The aim of this study was to assess the contamination levels with AFM1, of dairy products available in the Greek market (Thessaly), and also to estimate the relevant nutritional exposure. METHODS: A total of 52 infant milk, 25 Feta cheese and 32 pasteurized milk samples were randomly selected from the market. The determination of AFM1 was based on indirect immunoenzymatic ELISA method with two analytical packages; namely Tecna (Italy) and Prognosis Biotech (Greece), for comparison purposes, strictly following the manufacturer's instructions. The estimated daily intake (EDI) of AFM1 through dairy consumption and the relevant hazard index (HI) were calculated. RESULTS: The levels of AFM1, in all samples tested, were below the tolerable maximum level of 50 ng/L for milk and 25 ng/L for infant formulas (EC Regulation 1881/2006), while concentrations were very low (0.23-9.38 ng/L for infant formula, 0.54-4.09 ng/L for cheese and 0.20-17.84 ng/L for pasteurized milk). The exposure assessment revealed that infants, toddlers and children were the most exposed groups in AFM1 via milk and formula consumption (0.65, 0.35 and 0.35 respectively). The HI was also noticed higher in those ages, with the maximum value to reach 1.90. Though, for feta cheese the exposure was calculated as very low (EDI: 0.01 and HI: 0.05). Comparing the two analytical packages used, no statistically significant difference was found (p-value >0.05). CONCLUSIONS: Milk and dairy products tested were found safe for consumption, regarding the AFM1 levels. From a public health perspective, the results are satisfactory, given that the population exposure to AFM1, based on the nutrient profile, was rather limited.
