Consumer behaviour of young generation in slovakia towards cocoa-enriched honey

The new trend of healthy lifestyle increases consumers´ attention towards superfoods or functional food. Due to this fact, honey enriched with various healthy foods such as cocoa, cinnamon, ginger or dried fruits has started to appear on the European market. The aim of this research paper was to investigate consumer´s perception and preferences for cocoa-enriched honey. Consumer research was based on questionnaire survey extended by product testing. This survey was conducted in 2018 (February and March) and in total 257 young Slovak consumers between 18 - 30 years participated. Each respondent tested and evaluated sensory attributes of the product (taste, aroma, colour and texture) using a 5-point scale. Statistical analyses included Friedman test, Mann-Whitney U test, Fisher's Exact Test, Pearson Chi-square test and Cramer'V coefficient. Results showed that the cocoa-enriched honey was evaluated as tasty, aromatic, gently, delicious, special, with ideal sweetness and amount of cocoa. All sensory attributes were evaluated positively (2 - good). Females were more interested in the purchase of this product. Moreover, the product would be purchased mostly by respondents who consider it a healthier alternative to commercial chocolate spreads or by those who consider their eating habits healthy. Laboratory tests revealed that the antioxidant activity of the product was higher in comparison to normal honey. In conclusion, the obtained information could be used in product positioning, promotion and designing appropriate marketing strategy.

Overweight Or Obesity

Introduction: According to experts, overweight and obesity, are the most dangerous civilization diseases of today. World- wide, over 312 million people are obese and another 1.3 billion suffer from obesity. Increased weight is a significant health risk and it means a decrease in quality of life and, especially in life expectancy. Because of this, in our research, weaddressthe problem of current society which is overweight and obesity. Methods:To verify hypotheses, we used chi-square test of inde- pendence. It is a universal statistical test with wide use. It is most often used to verify the relation between nominal type variables. Results:By analyzing the results, we have found that over- weight or obesity of the parents, respondents’ satisfaction, eating habits and gender are related to overweight and obesity of the respondents. However, we have not found a relation between the physical activity of the respondents and their overweight or obesity. In case our respondents do not exercise and have bad eating habits, their body weight would be likely to increase. Conclusion:To prevent the development of overweight and obesity and its complications that have a negative impact on our health, it is necessary to make a targeted and effective in- tervention that is aimed at a healthy lifestyle.

Food Commodity

We live in an era when all circumstances on the market are changing rapidly, which leads consumers (even, if they are not aware of it) to certain behaviour that affects their daily activities. Lifestyle can be described as someone's way of living or the things that a person or a particular group of people usually do. It is included among the modern elements of consumer behaviour and also affects an individual´s decision-making process. The concerns over obesity and dangerous food ingredients have prompted a “healthy lifestyle” to become the latest trend in marketing. Therefore, the regular exercising, the reduction of stress, drinking enough water, and eating nutritious food takes on its importance. The main objective of the paper is to assess the consumer behaviour on the market of a selected food commodity. For this purpose, protein bars, which are part of diet not only of athletes but also of ordinary consumers, have been chosen. To achieve this main goal, a questionnaire was designed and data were collected from the respondents of the different age groups in the Slovak Republic. Based on the primary results, the authors of the paper can claim that more than 60% of the respondents try intentionally to choose better options of food as they want to live healthy. For a deeper analysis, the assumptions were formulated and subsequently verified by the Pearson Chi-square test of independence and Kolmogorov-Smirnov test. The paper provides useful information on consumer behaviour that can help not only producers and retailers but also to consumers themselves.

Objective: The use of drug coated balloon (DCB) for angioplasty has shown superior efficacy against plain balloons for treating complex infrainguinal arterial disease. We report and compare the clinical outcomes following application of DCB(Paclitaxel) and plain angioplasty (POBA) in our tertiary care centre. Methods: A retrospective, single centre analysis of 301 patients with chronic limb-threatening ischemia involving the infrainguinal segment was conducted between September 2014 and September 2018, after approval from the Institutional review board. We analyzed clinical outcomes by measuring postoperative ABI improvement, restenosis requiring reintervention procedure, minor and major amputations at the end of 18 months. . To find the association between the group variables (POBA and DCB) and other risk variables, Chi-square test/Fisher’s exact test was used. Multivariable logistic regression analysis was used. Results: Patients who underwent treatment with plain balloon (POBA) and DCB(Paclitaxel) angioplasty were 246(81.7%) and 55(18.3%) respectively. Our study group was predominantly male (Male: Female = 6.7:1), most patients were more than 50 years of age (n = 251, 83.4%). Smoking (n = 199, 66.1%) and diabetes (n = 210, 69.8%) were the most common atherosclerotic risk factors. Postoperative Ankle Brachial Pressure Index (ABI) improvement were similar in both groups (POBA = 57.7%; DCB = 69.8%; p = 0.103). Minor and major amputations following POBA were 26% and 22%; and DCB were 12.7% and 16.4% respectively. Re-stenosis requiring a re-interventional procedure within 18 months was 15%, (n = 37) following POBA; and 12.7% (n = 7) following DCB (p = 0.661). Conclusions: This retrospective study shows similar clinical limb related outcomes following POBA and DCB at 18 months. However, our comparative analysis between the POBA and DCB groups was totally unadjusted and not adjusted for common confounders such as age and sex. Hence, for one to draw definitive conclusions leading to changes in clinical practice; a randomized, prospective study with a larger patient cohort is needed.

Spinal cord lesions are included in the diagnosis of multiple sclerosis (MS), yet spinal cord MRI is not mandatory for diagnosis according to the latest revisions of the McDonald Criteria. We investigated the distribution of spinal cord lesions in MS patients and examined how it influences the fulfillment of the 2017 McDonald Criteria. Seventy-four patients with relapsing-remitting MS were examined with brain and entire spinal cord MRI. Sixty-five patients received contrast. The number and anatomical location of MS lesions were assessed along with the Expanded Disability Status Scale (EDSS). A Chi-square test, Fischer’s exact test, and one-sided McNemar’s test were used to test distributions. MS lesions were distributed throughout the spinal cord. Diagnosis of dissemination in space (DIS) was increased from 58/74 (78.4%) to 67/74 (90.5%) when adding cervical spinal cord MRI to brain MRI alone (p = 0.004). Diagnosis of dissemination in time (DIT) was not significantly increased when adding entire spinal cord MRI to brain MRI alone (p = 0.04). There was no association between the number of spinal cord lesions and the EDSS score (p = 0.71). MS lesions are present throughout the spinal cord, and spinal cord MRI may play an important role in the diagnosis and follow-up of MS patients.

Carbapenem Resistant Enterobacteriaceae

Abstract Background Carbapenem-resistant Enterobacteriaceae (CRE) are classified as an “urgent threat” to public health. Historically, colistin and tigecycline had been considered the drugs of choice for CRE infections, while other agents such as aminoglycosides and carbapenems had been used as adjunctive therapy. However, the FDA approval of ceftazidime-avibactam in 2015, meropenem-vaborbactam in 2017, and plazomicin in 2018 has expanded treatment options. Our purpose was to assess trends in CRE treatment for “new” antibiotics (ceftazidime-avibactam, meropenem-vaborbactam, plazomicin) as compared with other antibiotics with CRE activity. Methods This was a retrospective cohort study describing treatment of CRE blood stream infections (BSI) across 134 VA facilities from 2012-2018. Patients were censored at their first positive blood culture with CRE. Categorical data was assessed with a Fisher’s exact test or chi-square test. Trends test and logistic regression were used to describe changes in CRE treatment over time. Results 724 patients with positive blood cultures for CRE were identified during the study period. Most patients were male (94%), white (32%) or Hispanic (38%), and the mean age was 71.5+11.9. Of those patients that received antibiotics (N=697), 53.4% carbapenems, 40.3% received aminoglycosides, 39.3% received polymyxins, 32.9% penicillins, 32.6% extended spectrum cephalosporins, 26.1% fluoroquinolones, 11.6% ceftazidime/avibactam, and 0.4% ceftolazone/tazobactam. Over the study period, there was decreased utilization of aminoglycosides (P < 0.0026) and colistin (P< 0.002) and increases in extended spectrum cephalosporins (P < 0.001) and ceftazidime/avibactam (P < 0.001). Conclusion Utilization of “older” agents such as aminoglycosides and polymyxins for the treatment of CRE blood stream infections is decreasing in the VA. Treating CRE with ceftazidime/avibactam, a newly approved antibiotic, and extended spectrum cephalosporins are increasing. Disclosures All Authors: No reported disclosures

Abstract Background Human papillomavirus (HPV) type 16 accounts for a larger share of cervical cancer and has been a major health problem worldwide for decades. The progression of initial infection to cervical cancer has been linked to viral sequence properties; however, the role of HPV16 variants in the risk of cervical carcinogenesis, especially with longitudinal follow-up, is not fully understood in China. Methods We aimed to investigate the genetic variability of HPV16 E6 and E7 oncogenes in isolates from cervical exfoliated cells. Between December 2012 and December 2014, a total of 310 single HPV16-positive samples were selected from women living in the Taizhou area, China. Sequences of all E6 and E7 oncogenes were analysed by PCR-sequencing assay. Detailed sequence comparison, genetic heterogeneity analyses and maximum-likelihood phylogenetic tree construction were performed with BioEdit Sequence Alignment Editor and MEGA X software. Data for cytology tests and histological diagnoses were obtained from our Taizhou Area Study with longitudinal follow-up for at least 5 years. The relationship between HPV16 variants and cervical carcinogenesis risk was analysed by the chi-square test or Fisher’s exact test. Results In this study, we obtained 64 distinct variation patterns with the accession GenBank numbers MT681266-MT681329. Phylogenetic analysis revealed that 98.3% of HPV16 variants belong to lineage A, in which the A4 (Asian) sublineage was dominant (64.8%), followed by A2 (12.1%), A1 (11.4%), and A3 (10.0%). The A4 (Asian) sublineage had a higher risk of CIN2+ than the A1–3 (European) sublineages (OR = 2.69, 95% CI = 1.04–6.97, P < 0.05). Furthermore, nucleotide variation in HPV16 E6 T178G is associated with the development of cervical cancer. Conclusion These data could provide novel insights into the role of HPV16 variants in cervical carcinogenesis risk in China.

Abstract Estimation of allelic and genotypic distributions for continuous data using kernel density estimation is discussed and illustrated for some variable number of tandem repeat data. These kernel density estimates provide a useful representation of data when only some of the many variants at a locus are present in a sample. Two Hardy-Weinberg test procedures are introduced for continuous data: a continuous chi-square test with test statistic TCCS and a test based on Hellinger's distance with test statistic TCCS. Simulations are used to compare the powers of these tests to each other and to the powers of a test of intraclass correlation TIC, as well as to the power of Fisher's exact test TFET applied to discretized data. Results indicate that the power of TCCS is better than that of THD but neither is as powerful as TFET. The intraclass correlation test does not perform as well as the other tests examined in this article.

Although the issue of corporate culture has been taken over and addressed in the literature from various perspectives, there are very few researchers about the role of leadership and motivation in it, respectively very few researchers have addressed them as important components of the international company’s corporate culture. The present paper aims to point out that leadership and motivation can be perceived as important aspects of the international company’s corporate culture. The object of the investigation was an international company (situated in Italy) and its five subsidiaries (situated in Italy, Czech Republic, Germany, and Turkey). As the main research method, there was chosen the method of the questionnaire survey, which was attempted by all the company’s employees (totally 270 respondents). The questionnaire was divided into three separate, but logically related parts—leadership, motivation, and corporate culture, and submitted to two groups of respondents—the company’s management and its employees. In total 11 hypotheses were formulated and further evaluated by the methods of Pearson Chi-square Test, Fisher’s Exact Test, Cramer’s V coefficient, Kendall rank correlation coefficient, Eta coefficient, Spearman coefficient, Mann–Whitney U test and Wilcoxon W statistics, Kruskal–Wallis test, and Friedman’s test. The results of the research have proven that leadership and motivation are important parts of the corporate culture.

A binomial model is proposed for testing the significance of differences in binary response probabilities in two independent treatment groups. Without correction for continuity, the binomial statistic is essentially equivalent to Fisher’s exact probability. With correction for continuity, the binomial statistic approaches Pearson’s chi-square. Due to mutual dependence of the binomial and F distributions on the beta distribution, a simple F statistic can be used for computation instead of the binomial.

The Relationship

489 Background: Immune checkpoint inhibition (ICI) has greatly improved clinical outcomes for pts with mUC and other cancers. ICI is associated with a class of AEs, deemed irAEs due to immune activation. Nonetheless, biomarkers associated with irAE are still lacking. We hypothesized that the immune response against neoantigens is partly responsible for irAEs and investigated the association between irAEs, TMB and response to ICI. Methods: We identified patients with mUC at Dana Farber Cancer Institute who were treated with ICI (monotherapy or combination) and had available tumor sequencing data through Oncopanel. TMB was calculated using the number of non-synonymous exonic mutations per megabase. The severity of irAEs was graded using CTCAE v.5.0. Mann-Whitney U test was performed to identify association between TMB, incidence and grade of irAEs. A cut-off of 10/mb was assigned for TMB. Fisher’s exact test was used to evaluate the radiologic response between pts with and without irAEs and low vs. high TMB. Multivariable linear regression was used to assess the relationship between TMB, irAEs and response. p-values were adjusted using Benjamini-Hochberg method. Results: Of 101 pts with mUC who met the inclusion criteria, 32 (32%) reported irAEs. 6 (6%) were grade (G)1, 20 (20%) were G2, and 6 (6%) were G3. Median(m) time on therapy was 84 days for pts without irAEs and 88 days for pts with irAEs. Pts with irAEs had higher mTMB (15.4/mb) compared to pts with no irAEs (9.8) ( p = 0.01). In pts on monotherapy (93), those with irAEs (n=27) had a higher mTMB (15.13/mb) compared to pts with no irAEs (n=66) (mTMB = 10.20/mb) ( p = 0.01). Out of 94 pts with radiological data, response was achieved in 16 (50%) pts with irAE vs 10 (16%) pts with no irAE ( p < 0.001). When both irAE and response were included in a multivariable regression, the association between irAE and TMB was not significant ( p = 0.4). Pts with both irAE and high TMB had a response rate of 56% which was significantly higher than those with either irAE but low TMB (28.6%) or high TMB but no irAE (21.2 %) or low TMB and no irAE (10.3%) (Chi-square test p = 0.002; FDR corrected p-values for individual comparisons in Table). There was no association between TMB and irAE grade. Conclusions: Higher TMB was associated with higher incidence of irAEs in pts with mUC on ICIs. Moreover, pts with both high TMB and irAEs exhibited better response rates than those with only high TMB or irAEs, suggesting that they may provide complementary tumor and host characteristics. Further evaluation in mUC is needed to confirm this relationship between TMB, irAEs and response in a larger cohort and explore specific mutational signatures that may be associated with irAEs.
