Interactions between selected over-the-counter drugs and food: clinical relevance and prevention.

The use of medicines is associated with both therapeutic and adverse effects and interactions. In particular, interactions between drugs and food are common, and can either enhance the action of drugs or diminish their effect. Health professionals have a responsibility to screen for and educate patients about food-drug interactions, as well as to assist in decreasing their occurrence. The aim of this study was to identify any interactions present between food and selected over-the-counter (OTC) drugs. Sixty-five publications out of a potential 1112 found in the search were included in the study and among them 28 concerned painkillers, 6 - antihistamines, 4 - nasal decongestants, 10 were for proton pump inhibitors and for iron and 8 for sildenafil. Interactions between food and OTC drugs do exist. These drugs should not be taken regardless of the meal. Providing relevant information to the patient will increase drug safety and efficacy.

Associations of ESR1 and ESR2 gene polymorphisms with metabolic syndrome and its components in postmenopausal women.

OBJECTIVES: Metabolic syndrome (MS) affects a quarter of Polish people and is associated with diabetes mellitus type 2 and ischemic heart disease. The prevalence of MS in postmenopausal women can be increased by the lack of protective effects of oestrogens. In the near future, because of the general increase in life expectancy, the number of postmenopausal women will rise substantially. Therefore, investigating both the environmental and the genetic factors predisposing to MS may have a great impact on women's health. The aim of this study was to determine whether particular oestrogen receptor (ESR) gene polymorphisms can predispose to the development of MS in women after menopause. STUDY DESIGN: The sample consisted of 147 postmenopausal women. In addition to collecting medical history and analyzing body composition using the TANITA scale, patient's waist size, blood pressure, serum lipids, glucose, insulin, C-reactive protein and adiponectin were measured. The analysis of ESR gene polymorphisms was performed using the Sequenom MassARRAY platform. RESULTS: Three out of ten analyzed polymorphisms in the ESR1 gene (rs2234693, rs6902771, rs7774230) and one out of eight analyzed polymorphisms in the ESR2 gene (rs3020449) were associated with MS. The ESR1 rs2234693, rs6902771 and rs7774230 polymorphisms were associated with serum concentrations of high-density lipoproteins. The ESR2 rs3020449 polymorphism was associated with serum concentrations of total cholesterol and low-density lipoprotein. Four ESR1 polymorphisms (rs1709183, rs2234693, rs6902771, rs7774230) were associated with total fat tissue content. CONCLUSIONS: Bearing the particular alleles at the ESR gene polymorphisms may impact the development of MS and some of the ESR polymorphisms may influence serum cholesterol concentrations in women after menopause.

Bad eating habits as the main cause of obesity among children.

Obesity is undoubtedly one of the biggest medical problems of the 21st century. Regrettably, the problem affects more and more children and adolescents. 10% of world's school-aged children have an excess body weight and a quarter of these children are obese. In Europe every fifth school-aged child suffers from an excess body weight. The prevalence of overweight and obesity among Polish adolescents is about 14%. An excess body weight can be the consequence of genetic factors, endocrine disorders or certain drugs. However, "simple obesity" is the most common, consequence of providing too much energy from food products in comparison to energy expenditure (caloric excess). Today's lifestyle promotes the development of obesity. The lack of physical activity, sedentary lifestyle and energy-rich diet are the main causes of an excess body fat accumulation. Because of improper eating behaviours children consume an excess amount of energy; and their diet is deficient in elements necessary for proper development. The examples of such bad eating habits are: snacking highly processed and calorie-rich foods between meals eating in front of the TV screen, skipping breakfasts, drinking sugar-sweetened beverages, "eating out" frequently and "emotional eating". Bad eating behaviours are crucial factors for the development of obesity. Eating habits are usually formed in early childhood and parents play a very important role in their development.
