Inflammatory bowel disease (IBD) is a chronic disease with periods of exacerbation and remission of the disease. The etiology of IBD is not fully understood. Many studies point to the presence of genetic, immunological, environmental, and microbiological factors and the interactions between them in the occurrence of IBD. The review looks at genetic factors in the context of both IBD predisposition and pharmacogenetics.
A sedentary lifestyle and inadequate nutrition often leads to disturbances in intestinal homeostasis, which may predispose people to excess body weight and metabolic syndrome. Obesity is frequently observed in patients with inflammatory bowel diseases (IBD), similar to the general population. Obesity may exert a negative effect on the course of IBD as well as reduce the response to treatment. Moreover, it may also be an additional risk factor for vein thromboembolism during the flare. In both obesity and IBD, it is of great importance to implement proper dietary ingredients that exert desirable effect on gut microbiota. The key to reducing body mass index (BMI) and alleviating the course of IBD is preserving healthy intestinal microflora.
According to the available data, environmental pollution is a serious problem all over the world. Between 2015 and 2016, pollution was responsible for approximately nine million deaths worldwide. They also include endocrine disrupting chemicals (EDCs) that can interfere with the functioning of the thyroid gland. They are characterized by high persistence in the environment. These substances can enter the body through the gastrointestinal tract, respiratory system, as well as contact with the skin and overcome the placental barrier. EDC can be found in food, water, and personal care products. They can get into food from the environment and as a result of their migration to food products and cosmetics from packaging. EDCs can disrupt the functioning of the thyroid gland through a number of mechanisms, including disrupting the activation of thyroid receptors and the expression of genes that are related to the metabolism, synthesis, and transport of thyroid hormones (HT). There is a need to strengthen the food safety policy that aimed at the use of appropriate materials in direct contact with food. At the same time, an important action is to reduce the production of all waste and, when possible, use biodegradable packaging, which may contribute to the improvement of the quality of the entire ecosystem and the health of food, thus reducing the risk of developing thyroid diseases.
Optimization of energy intake in the diet of young athletes is of primary importance. In addition to the energy expenditure associated with their body development, the demand resulting from intensive physical activity also increases. The aim of this study was to compare the accuracy of formulas commonly used for resting energy expenditure (REE) calculations with values obtained from measurements using indirect calorimetry among male children and adolescents practicing football. The study was conducted among 184 boys aged 9 to 17 using a calorimeter and a device for assessing body composition by means of electrical bioimpedance using a segment analyzer. The mean error ranged from −477 kcal/d by the Maffeis formula to −182 kcal/d for the Institute of Medicine of the National Academies (IMNA) formula. A statistically significant difference was found for all formulas in the calculated value in relation to the measured REE value (p < 0.0001). Most “ready-to-use” formulas underestimate REE, which can be a risk in determining the total energy demand in a group that requires more calories, especially when due to intensive growth and development and the expenditure associated with regular training and increased physical activity.
The incidences of colorectal cancer and inflammatory bowel diseases are increasing in the developed countries of Western Europe and North America, and consequently, the prevalence rate of temporary or permanent stomas has increased in recent years. Nevertheless, the amount of research in the nutrition field in the case of patients with stoma is rather limited. This review article aims to assess the impact of nutrition on an intestinal stoma and possible sequelae resolved with nutritional therapy. The research analyses conducted thus far indicate a significantly increased risk of developing malnutrition, vitamin deficiency (especially group B), and an increased number of discharges from the stoma and its relevance with abnormalities found in electrolyte concentrations.
Background. The dynamic development and change of rural lifestyle patterns towards urban patterns has been noticeable since the second half of the 20th century. Nutrition, as well as the lifestyle in urban and rural areas, has undergone a process of urbanization, which is evidenced by the following an increasing number of overweight people. Objective. The aim of the study was to compare eating habits and frequency of consumption of selected groups of products between the urban and rural residents from the Subcarpathian voivodeship. Material and methods. The survey was carried out on a sample of 279 persons from urban and rural areas of Subcarpathian voivodeship. In this study, the diagnostic survey method consisting of 3 (different) parts was used. To check the significance of differences, U Mann-Whitney and Kruskal-Wallis tests were used; whereas correlations between variables were determined by the Spearman's rank of correlation coefficient and Pearson's chi-quadrat test. Results. In the part concerning eating habits, statistically significant differences occurred among others; for the circumstances of eating meals, the most commonly consumed snacks, food processing techniques and the most frequently selected fat. In the part concerning the frequency of consumption of individual product groups, significant differences occurred among others; for dairy products, grain products, fast food, alcohol. There was a correlation between the frequency of consumption of individual products and socioeconomic status. Conclusions. The quality of the diet and eating habits of urban and rural residents of Subcarpathian voivodeship does not differ significantly. The detected differences in eating habits were more influenced by the education and socioeconomic status of the examined group than the place of residence.
Inflammatory bowel diseases (IBDs) are a group of chronic diseases characterized by recurring periods of exacerbation and remission. Fibrosis of the intestine is one of the most common complications of IBD. Based on current analyses, it is evident that genetic factors and mechanisms, as well as epigenetic factors, play a role in the induction and progression of intestinal fibrosis in IBD. Key genetic factors and mechanisms that appear to be significant include NOD2, TGF-β, TLRs, Il23R, and ATG16L1. Deoxyribonucleic acid (DNA) methylation, histone modification, and ribonucleic acid (RNA) interference are the primary epigenetic mechanisms. Genetic and epigenetic mechanisms, which seem to be important in the pathophysiology and progression of IBD, may potentially be used in targeted therapy in the future. Therefore, the aim of this study was to gather and discuss selected mechanisms and genetic factors, as well as epigenetic factors.
