Evaluation of the nutritional quality of veal supplemented with organic selenium and its effect on selenium status of people

In the first stage of our research we found out a higher content of selenium in the meat of calves of experimental group (with added the organic form of selenium to the feed mixture) compared to control group (fed without organic form of selenium). In the second stage of our research we focused on monitoring the impact of selenium enriched veal meat and on selenium concentration in blood serum and the selected biochemical parameters of lipid spectrum of the experimental group of volunteers. Ten people who were participating in the research were at the age range between 29 - 56 years. All the volunteers consumed veal meat enriched with organic selenium for 4 weeks. Before starting the experiment we took venous blood of the volunteers and this blood was considered as a control sample of selenium in blood serum of the experimental group. Selenium concentration in blood serum of the examined group was determined by an average of 58.31 ±5.36 mg.L.-1 and none of them reached the optimal level of selenium. Consequently, we carried out the additional blood sampling after 2 and 4 weeks of the consumption of veal meat. There was registered a slight increasing of selenium status, whereas after the finishing the consumption, we determined the average selenium concentration in blood serum of the experimental group 60.73 ±4.05 mg.L-1. The evaluation of lipid profile of the experimental group showed (after input blood sampling) higher values of total cholesterol level and lower levels of HDL cholesterol. This fact shows the higher risk of starting the cardiovascular diseases. Reported research results didn't show statistically significant changes of blood lipid spectrum of the experimental group. We concluded that the consumption of supplemented veal meat can positively affect the level of selenium in our body and thereby increase it can increase the protective effect against the influence of free radicals

Effect of short-term consumption bitter apricot seeds on the body composition in healthy population

The distribution of fat in different areas of the body is important since accumulation of fat within the abdominal cavity represents a much more severe cardiovascular risk than accumulation in subcutaneous adipose tissues. Apricot seeds contain a wide variety of bioactive compounds and that consumption can decrease blood pressure and total blood cholesterol levels, fight oxidative stress and maintain body weight. The aim of the study was to analyse body composition: body fat mass (BFM), fat free mass (FFM), skeletal muscle mass (SMM), body fat percentage (%BFM), visceral fat area (VFA), total body water (TBW) - intracellular water (ICW) and extracellular water (ECW) and to evaluate the changes that occur after 6-weeks consumption of bitter apricot seeds. The study group finally consisted of 34 healthy adults volunteers (21 females and 13 males). Volunteers were recruited from the general population of Slovakia. Respondents were 23 - 65 years old, where the average age of women was 40.65 ±11.31 years and the average age of men was 36.91 ±9.98 years. All participants were asked to consume 60 mg.kg-1 of body weight of bitter apricot seeds daily during 6 weeks. Body composition was diagnosed by multi-frequency bioelectrical impedance analysis (MFBIA) by InBody 720 (Biospace Co., Korea), which measures the total impedance at frequencies of 1, 5, 50, 100, 500, 1000 kHz. At baseline mean body weight was 85.78 ±14.66 and 62.84 ±12.19 kg in the male and female participants, respectively. After 6 weeks of consumation we observed non-significant decreasing of mean body weight. The mean BFM was 19.25 ±8.81 kg in the male group and 19.47 ±7.21 kg in the female group. After six weeks, BFM decreased non-significantly (on average 0.5 kg) in both groups. The mean FFM at baseline was 43.37 ±5.98 and 66.54 ±7.98 kg in the female and male participants, respectively. The statistical analysis confirmed that the increase of FFM (43.37 ±5.98 kg to 43.56 ±5.80 kg) in the female were statistically significant (p <0.05). VFA was greater in the men (82.04 ±39.82 cm2 at baseline and 78.65 ±39.79 cm2 after 6 weeks) comparison to women (79.82 ±29.03 cm2 at baseline and 78.29 ±29.90 cm2 after 6 weeks). The mean of TBW in males before the start of study was 48.78 ±5.77 kg and 47.88 ±5.57 kg after 6 weeks of consumption. The results of study show the small weight loss in the both group. Therefore, the results from this study indicate that daily consumption of bitter apricot seeds produce measurable health benefits, but further studies are also required

Dietary patterns and lifestyle of patients with myocardial infarction

Civilization diseases, including cardiovascular, are major health problems in current modern society. Numerous studies provided sufficient evidence that variety of risk factors are involved in cardiovascular diseases formation. Of the most important is the lifestyle that largely contributes to our health, up to 50 - 60%. Lifestyle includes all modifiable risk factors that together affect the development of these diseases. In our study we searched and evaluated the nutritional parameters and lifestyle of patients hospitalized in Cardiocentre Nitra. In order to obtain the necessary information we chose the questionnaire method. In our survey 194 patients were included, of which 155 were men (79.89%) and 39 (20.11%) women. These patients were hospitalized with acute myocardial infarction diagnosis. The vast majority of patients had overweight and obesity caused by improper eating habits. The high prevalence of overweight, BMI in the range 25 - 30 kg/m2, was also confirmed as statistically significant, p <0.05 (P=0.02). BMI over 25 kg/m2 was present in 85% of men and 80% of women. The consumption of selected food commodities with evidence of a positive or negative impact on the emergence of acute myocardial infarction was not statistically significant (p >0.05) when evaluating dietary habits. But we can confirm too frequent consumption of chicken at the expense of other types of meat and relatively frequent consumption of fish (once a week). We recorded the preference of semi-skimmed dairy products, but also high and inappropriate consumption of full-fat dairy products in men and women (37% and 17.8%, respectively). Daily intake of fruits and vegetables was in 85.9% of women and 64.7% of men. Everyday intake of bread and pastries was confirmed by 100% of respondents. Lifestyle was evaluated according to the presence of smoking, excessive alcohol consumption, and physical activity. Up to 60.5% of men and 26.4% of women admitted smoking, while 34.6% of men and 7.5% women ended up with the habit after myocardial infarction. The excessive alcohol consumption was not detected in the study group. Approximately 67% of men and 56% of women carry out an easier walking and moderate physical activity while taking into account their health status

Nutrigenomics analyze of expression of extracellular leptin receptor by the following essential oil monitoring at the avian models

Leptin gene was identified in 1994 by positional cloning. His mutation is considered extreme obesity surface phenotype and infertility in ob/ob mice. Most of the research, which followed the discovery of this hormone, focused on the role of leptin in regulating body weight,  in order to clarify the pathophysiology of obesity. Many research results show that leptin is not only important in regulating food intake and energy balance, but also performs functions such as metabolic and neuroendocrine hormone. Using herbs and essential oils depends on their antimicrobial activity. Most plants have favorable multifunctional properties, which are the specific content of bioactive components. Some authors characterize fytogénne substance such as natural substancese plant origin, which leave no residues in animal products and is not necessary to keep the trade period before slaughter animals. Analyses suggest that the structural function of the receptor exists as a dimer constructively in the plasma membrane. Each receptor dimer pair is reversibly bound to one molecule of leptin. When bound, signaling pathways are responsible for beginning the activation receptor associated Janus kinase 2 (JAK2) and tyrosine phosphorylation of two key residues in the intracellular part of receptor

Benefits of sea buckthorn juice consumption in women of productive age with hypercholesterolemia

Background. Sea buckthorn contains almost 200 nutrients and bioactive substances, including phenolic compounds such as flavonoids, vitamins, proteins, amino acids, minerals, alkaloids, chlorophyll derivatives, amines, organic acids, fatty acids and phytosterols. Human and animal studies suggest that sea buckthorn may have a variety of beneficial effects: cardioprotective, antiatherogenic, antioxidant, anticancer, immunomodulatory, antibacterial, antiviral and antiinflammatory. Objective. The aim of this study was to evaluate the effect of regular consumption of 100% sea buckthorn juice on the risk factors of cardiovascular diseases in women of productive age with hypercholesterolemia. Material and Methods. A clinical study involved 19 women with a mean age of 54.06 ±2.97 years who consumed 50 mL of sea buckthorn juice daily for 8 weeks. Anthropometric and biochemical parameters in blood serum were monitored before the start of sea buckthorn consumption and after 8 weeks of consumption. Body composition was determined using an multifrequency analyzer InBody720. Routine biochemical analyzes were performed by standard methods in an accredited laboratory of the University Hospital by automatic biochemical analyzer BioMajesty JCA-BM6010/C. Statistical comparison between individual measurements was performed using a paired t-test, using Statistica Cz version 10 (TIBCO Software, Inc., Palo Alto, CA, USA). Results. We observed significant decrease of body weight, body mass index (P0.05). After the intervention, we observed decrease of orosomucoid, immunoglobulin A, immunoglobulin G, immunoglobulin M (P<0.001) and C-reactive protein (P<0.01). Conclusions. The obtained results support the hypothesis that the daily consumption of sea buckthorn juice for eight weeks could contribute to the beneficial effects of reducing the risk of cardiovascular diseases, such as the reduction of body and visceral fat, LDL-C, CRP and the increase of HDL-C

The effect of the regular consumption of lard from fats of crossbreed Mangalitsa and breed of meat type pig on the lipid profile of consumers

The aim of this study was to evaluate the influence of consumption of lard processed from crossbreed of the original mangalitsa genotype and the breed of meat type pigs on selected biochemical parameters: total cholesterol (T-C), LDL cholesterol, HDL cholesterol and triacylglycerols (TAG). Twenty-nine probands participated in the study, of which 14 women and 15 men (aged 21 - 59) who consumed regularly lard four times a week during 5 weeks. By evaluating the lipid profile of probands, we observed elevated hypercholesterolemia at the beginning of the study in 43% women and 27% men. Statistically significant differences were recorded in this group of probands, where we recorded a decrease in TC of 0.55 mmol.L-1 in the whole sample of probands with p &lt;0.05 probability in the 2nd sample of study after 5 weeks of consumption of lard. Borderline high (up to 3.35 mmol.L-1) was found in 21% of women and 33% of men, and above LDL cholesterol was found in 79% of women and 60% of men. This high level of LDL cholesterol is considered a risk factor for the development of atherosclerosis. We can conclude from the results that regular consumption of lard has significantly reduced the total cholesterol levels, especially in women, this effect has been associated with lowering LDL cholesterol (p &lt;0.01) and lowering HDL cholesterol.&nbsp; Normal 0 21 false false false SK X-NONE X-NONE <w:LsdException Locked="false" Priority="73" Name="Colorful Grid Accent

Psychosocial Risks at the Workplace in Unexpected Emergencies

Psychosociální rizika na pracovišti a pracovní stres vyplývají nejen z náročného charakteru a nevhodné organizace práce, ale také z nevyhovujících mezilidských vztahů na pracovišti či nemožnosti vyvážení pracovního a osobního života. Jejich vliv může mít výrazný negativní dopad jak na psychické, tak i fyzické zdraví zaměstnanců, jejich pracovní výkon, absentismus, fluktuaci, pracovní neschopnost i úrazovost. Celosvětová koronavirová krize nás přiměla k zamyšlení nad dopadem neočekávaných situací na úroveň psychosociálních rizik při práci.Psychosocial risks at the workplace are connected with the demanding character and inappropriate organization of work, with the unsatisfactory human relations at work place and with the impossibility to balance work and personal life. They can negatively influence either mental or physical health of an employee, the job performance, absentism, employee turnover, absence at work from the health reasons and work injuries. The global coronavirus crisis has prompted us to think over the impact of unexpected situations on the level of psychosocial risks at work
