The unique project “Health Steps – education and learning as a determinant of a healthy and open society” was implemented as part of the “Social Responsibility of Science” programme funded by the Ministry of Education and Science. This innovative initiative was led by the Medical University of Silesia in Katowice (SUM), the Regional In-Service Teacher Training Centre “Metisˮ and the Iskierka Foundation. The project aimed to increase the responsibility of teachers and legal guardians of healthy children and to instil in each group the awareness that taking care of physical health, mental health, and proper nutrition significantly impacts the quality of life. The project identifies eight broad tasks to enhance knowledge, practical skills, and social competencies in three thematic areas: physioprophylaxis, diet prevention, as well as mental health and oncology prevention. As part of physio prophylaxis, educational films on correct posture were realised, preventive posture examinations were conducted among children, and training workshops on ergonomics and adopting correct body positions while learning and playing were held. During the stage related to diet prevention, screening tests for overweight and obesity were carried out, including anthropometric tests, i.e. measurement of body height, body weight and body composition analysis among children. Eating behaviour and attitudes towards nutrition among children and their parents were studied, and a dietary intervention combined with nutrition education was implemented. Workshops conducted for teachers on the educational method of drama and supervision were aimed at enhancing educators’ competence in using these methods in health education. Extending care to children and adolescents is justified because their lifestyle habits depend on the environment in which they are raised (parents, teachers, peers). Informed participation in such projects allows them to take conscious control of their health in collaboration with an interdisciplinary team of professionals.

Introduction: The study aimed to assess the prevalence of overweight and obesity in adolescents aged 11–13 and compare the body weight and body fat content of students in general and sports classes. Material and methods: The pilot study involved 352 pupils in grades 6 and 7 from primary schools in Bytom, participating in the project “Health Steps – education and learning as a determinant of a healthy and open society”. The study was meticulously conducted, with careful attention to detail and consideration of the class profile. A sports class, implementing 10 hours of physical education per week, was compared to a general class with 4 hours. To ensure the accuracy of the results, body composition was assessed using bioelectrical impedance analysis (BIA), a widely accepted method. Polish centile grids, a reliable tool, were used to assess body mass index (BMI). Age and gender-specific norms for adolescents were also employed to assess normal body fat, further enhancing the study’s validity. Results: In the general profile classes, 77 (25.58%) pupils were overweight, including 36 (22.78%) girls and 41 (28.67%) boys. In sports profile classes, it affected 8 (15.69%) pupils, including 2 (10.53%) girls and 6 (18.75%) boys. In the sports classes, obesity did not occur, while in the general profile classes it affected 13 (4.32%) pupils, including 6 (3.80%) girls and 7 (4.90%) boys. Regarding body fat percentage, 56 (15.91%) students were overweight. Conclusions: The study’s key findings reveal that over 25% of adolescents have excessive body weight, with overweight and obesity being less common among pupils in sports classes. Furthermore, over 30% of children have excessive body fat. Notably, girls in sports classes were less likely to be overweight and obese than girls in general profile classes. However, the differences in body fat among boys in the sports and general classes were not statistically significant.

The prevention of overweight and obesity in children and adolescents focuses on education and the promotion of healthy lifestyles. The World Health Organization indicates that the level of obesity-related diseases has increased almost threefold since 1975, now affecting all socioeconomic groups regardless of age or ethnicity. Particularly alarming is the increase in obesity among children and adolescents. Projections indicate that by 2025 the disease could affect up to 268 million young people aged 5–17. The causes of the problem are complex, involving genetic and environmental factors, psychological factors, as well as inappropriate eating behaviors and insufficient levels of physical activity. In Poland, the lack of precise epidemiological data and systematic control of the problem of obesity among children and adolescents is a major challenge. It is important to take effective preventive measures, including nutrition education and the promotion of physical activity to change habits and prevent obesity. Projects such as “Colorfully means healthy”, “6–10–14 for Health”, and “Healthy Me” indicate the need for a multifaceted approach to the problem, involving government institutions, schools, families and non-governmental organizations. A successful fight against obesity requires long-term strategies, comprehensive educational and health activities that will promote healthy choices and change social attitudes toward nutrition and physical activity. Implementing these strategies is key to improving the quality of life and health of children and adolescents, as well as to reducing the long-term health and social consequences associated with obesity.

Background/Objectives: Increasing drugs’ stability and adequately protecting them against degradation will ensure a decrease in their price and broader availability of pharmaceutical substances. This is of great importance, especially for drugs used to treat the most common diseases in the population, such as hypertension. The study examined two newly synthesized substances from the angiotensin I-converting enzyme inhibitor (ACEI) group as potential drugs. ACEIs are among the leading drugs used in the treatment of hypertension in the world. The chemical modifications of the tested substances applied concerned the places most susceptible to degradation. The presented work analyzed the compatibility of new derivatives with selected excipients used in pharmacy. Methods: Thermogravimetric (TGA) and differential thermal analyses (c-DTA) were used as the main methods. In addition, non-thermal methods such as colorimetry analysis, Fourier-transform infrared (FTIR) and UV spectroscopy were used. Results: Based on the conducted studies, it can be concluded that the incompatibility of IND-1 with glucose anhydrous and lactose monohydrate occurs only when the mixture is stored at higher temperatures. For the remaining IND-1 and IND-2 mixtures with excipients, compatibility was demonstrated. Conclusions: The obtained results confirmed the usefulness of the applied thermal analyses (TGA and c-DTA) for assessing the compatibility of the tested potential drugs with excipients. However, in the case of incompatibility reactions of substances occurring under the influence of elevated temperatures, such as the Maillard reaction, it is necessary to use non-thermal methods to obtain the right result.

IntroductionEnsuring a sustainable and responsible diet, particularly in the procurement of fatty products, holds paramount importance for early childhood development. Dietary fats significantly influence children’s growth and well-being, both in the short and long term. Schools and kindergartens play a pivotal role in shaping children’s dietary habits. This study aims to quantitatively and qualitatively analyze public procurement orders conducted by educational institutions.Materials and methodsOut of 1,126 public procurement orders, 197 met inclusion criteria, leading to the identification of 1,248 products categorized as sources of fats in children’s diets. The study conducted both quantitative and qualitative analyses on the identified products.ResultsCriteria commonly employed by purchasers were derived from product descriptions. While product composition, especially fat content and the absence of certain additives, received due attention, organoleptic characteristics criteria were frequently overlooked. Sustainable procurement criteria were given the least consideration. The study highlights a notable reliance on vegetable oils, predominantly rapeseed oil. However, it reveals a worrisome prevalence of animal-derived fats, including butter, mayonnaise, pork belly, and lard. Although plant-based fats constitute around 52.77% of total orders, the substantial presence of animal fats poses challenges to maintaining a balanced and healthy diet for children.ConclusionThe study underscores the necessity of establishing specific criteria for evaluating the quality of delivered products, especially fatty items, in educational settings. Standardized guidelines are crucial to promote healthier food choices, encourage sustainable diets, and ultimately enhance the overall health and well-being of children.

Anthropometric indices, such as the BMI (body mass index), WC (waist circumference), and WHR (waist–hip ratio) are commonly used for cardiometabolic risk assessment. Consequently, in the context of evaluating cardiometabolic risk in the post-MI population, it is worthwhile to consider indices such as the Visceral Adiposity Index (VAI) and Body Adiposity Index (BAI), which have emerged as valuable risk assessment tools in clinical trials. The aim of this study was to provide a more comprehensive understanding of the importance of anthropometric indices and body composition analysis in evaluating the cardiometabolic risk among post-myocardial infarction patients. In the pursuit of this objective, this study involved assessing the BMI, WC, WHR, WHtR, VAI, BAI, and body composition in a population of patients. This study enrolled a total of 120 patients hospitalised at the Silesian Centre for Heart Diseases (SCCS) due to MI, and body composition analysis evaluated various parameters including the percentage of adipose tissue (FatP) [%], total adipose tissue (FatM) [kg], fat-free mass (FFM) [kg], muscle mass (PMM) [kg], total body water (TBW) [kg], and visceral adipose tissue (VFAT). The mean BMI for the entire group was 27.76 ± 4.08, with women exhibiting a significantly lower value compared with men (26.66 ± 3.33 vs. 28.16 ± 4.27). The mean values obtained for the WHR, WHtR, BAI, and VAI were 0.97 ± 0.08, 0.59 ± 0.07, 28.37 ± 5.03, and 3.08 ± 3.50, respectively. Based on the visceral adiposity index (VAI), in 47.5% patients, there was no adipose tissue dysfunction, with a higher proportion among women (71.88%) compared with men (38.64%). What raises concern is that 32.50% of patients had acute ATD, with a significantly higher prevalence among men (38.64%) compared with women (15.63%). Conclusion: The study results suggest that the BMI, WC, and WHR have their limitations, whereas the WHtR, VAI, and BAI provide a more comprehensive view of cardiometabolic risk, especially in the context of adipose tissue distribution and its metabolic consequences. Incorporating the WHtR, VAI, and BAI into routine clinical practice may enhance the management of cardiometabolic risk, especially among post-MI patients.

IntroductionPublic procurement of food is key to ensuring proper nutrition with high-quality products in public institutions such as schools and kindergartens. However, it should not be considered a mandatory expenditure from public finances but rather an investment in health promotion.Materials and methodsA total of 1,126 public procurement orders processed by schools and kindergartens in Poland during the period from November 2022 to March 2023 were analyzed. Ultimately, 197 public procurement orders meeting the inclusion criteria were considered for analysis. Based on these orders, 2,753 food products classified as dairy and its derivatives were extracted. The ordered quantities of individual products were analyzed, as well as their descriptions (quality characteristics).ResultsCriteria related to composition were most commonly described, the most common criterion was the fat content and the absence of preservatives. On the second places were organoleptic characteristics, where taste and consistency expectations were most frequently specified. Sustainable public procurement criteria were the least frequently mentioned and were treated as highly marginal.ConclusionIntroducing minimum standards for the descriptions of dairy products in terms of organoleptic characteristics, composition features, and sustainability criteria will improve the quality of dairy products supplied to public institutions, particularly schools and kindergartens.

IntroductionUnhealthy lifestyle behaviours that may contribute to the development of disorders leading to MI include consuming foods with a high glycaemic load and excessive supply of saturated fats, especially trans fats. Limiting the consumption of simple and refined carbohydrates, such as sweets, sweet drinks, white bread, or white pasta, has a positive effect on the lipid profile by lowering the concentration of triglycerides. Eliminating simple sugars, especially fructose, prevents the deposition of visceral adipose tissue.Materials and methodsThe study included 116 patients of the Silesian Centre for Heart Diseases in Zabrze (SCCS; Poland), with their average age being 59.45 ± 11.54 years, staying in the SCCS due to MI, from March to November 2022. The comprehensive assessment of diet quality included 72 patients: 15 women and 57 men. The research tool was the KomPAN questionnaire for examining dietary views and habits, developed by the Committee on Human Nutrition Science of the Polish Academy of Sciences, evaluating the diet in the year preceding the study. The following three indicators were used to assess the diet quality: pro-Healthy Diet Index (pHDI), non-Healthy Diet Index (nHDI) and Diet Quality Index (DQI).ResultsMost patients ate white wheat bread several times a day (39.66% of patients, with a higher percentage in men than in women – 42.35% vs. 32.26%), and white rice, fine-ground groats and pasta once a week (40.52% of patients, including 41.17% of men and 38.71% of women). Legume seeds were predominantly eaten 1–3 times a month (51.73% of responses, with comparable percentages of men and women, i.e., 51.76% vs. 51.62%), vegetables several times a week (42.25% of responses, including more women than men, i.e., 54.84% vs. 37.64%), and fruit once a day (40.52% of responses, including more men than women: 45.89% vs. 25.81%).ConclusionThe results of our assessment of individual behaviours of the whole group may indicate errors in the diet. The value of the pro-Healthy Diet Index appears to confirm this fact, while the non-Healthy Diet Index and Diet Quality Index values do not clearly demonstrate its potential adverse impact on health. These limitations of our study may be due to differences in the size of the study population and the size of the population included in the comprehensive diet assessment. Therefore, it seems necessary to conduct further research.

Proper nutrition during the first period of life is primarily related to meeting energy needs and providing essential nutrients that ensure the infant’s normal physical and psychomotor development. Improper nutrition during this period, inadequate amounts of nutrients, inappropriate timing and manner of introduction of individual foods, can permanently alter metabolism and the course of physiological processes, increasing the risk of diseases such as obesity, allergic diseases, and cardiovascular diseases. This study aimed to verify how the method of complementary feeding influences the occurrence of food neophobia between 2 and 7 years of age, as well as to assess the different nutritional aspects resulting from the process of starting feeding other than breast milk and milk formula. In this study, 490 mothers and their children aged 2–7 years participated. The research tool was a questionnaire consisting of a child’s dietary assessment and standardized questionnaires assessing food neophobia among children: Food Neophobia Scale for Children (FNSC) and the Montreal Children’s Hospital-Pediatric Feeding (MCH-FS). In the study group of children, 238 (48.57%) had no Baby-Led Weaning Method (no BLW) method used during complementary feeding (CF), and 252 (51.42%) children used Baby-Led Weaning Method (BLW). According to the FNSC questionnaire, a high risk of food neophobia was found in 32.65% of the children studied and a medium risk in 39.80%. The medium risk of feeding problem occured in 11.63% of children, the high risk in 6.73% of children, and the highest risk in 6.94% (MCH-FS). No statistically significant differences were observed between the BLW and NoBLW groups. High risk of food neophobia occured in 1/3 of the children studied, but there was no relationship in the study group between the mode of CF (BLW/NoBLW) and the risk of food neophobia.

Professional football players are obligated to meet the physical demands and maintain the best possible performance throughout the whole macrocycle. It is important to assess the players' nutrition knowledge, identify areas that require increased nutrition awareness and identify the impact of knowledge on changes in body composition as this can affect the players' health and performance. This study aimed to assess changes in the body composition of professional football players during the macrocycle of the spring round of the football championship and to identify the correlation between nutrition knowledge and maintaining body composition. The study included 38 football players. The players' body compositions were analyzed 6 times during the macrocycle consisting of preparatory, competitive, and transition periods using the Direct Segmental Multi-Frequency Bioelectrical Impedance Analysis method. Athletes completed the Nutrition for Sport Knowledge Questionnaire to assess their nutrition knowledge. During the preparatory period, a statistically significant negative correlation was demonstrated between the players' knowledge about the subsections of micronutrients in the diet and the dispersion of the adipose percentage tissue content (r = −0.36, p = 0.03). In the competitive period, there was a statistically significant negative correlation between the players' knowledge of sports nutrition and the dispersion of lean body mass (r = −0.46, p = 0.004), and skeletal muscle mass (r = −0.36, p = 0.03). During the transition period, a statistically significant negative correlation between the players' knowledge of weight control and the dispersion of body mass (r = −0.47, p = 0.00) and BMI values (r = −0.48, p = 0.00) was identified. The player's knowledge about the subsection of macronutrients significantly negatively correlated with the dispersion of skeletal muscle mass content (r = −0.33, p = 0.05). Nutrition knowledge has an impact on the stability of body composition during all analyzed periods: preparatory, competitive, and transition periods.

Baby-led weaning (BLW) is an increasingly well-known method of complementary feeding for infants. The BLW method is based on the fact that the baby becomes physically ready to eat on its own and can henceforth effectively supplement its diet, which was previously based on breast milk or formula milk. The aim of the study was to compare complementary feeding among mothers using and not using the BLW method. The study took into account, among other things, the frequency of spoon feeding, eating from the family table, and eating meals with a pulpy consistency. The study also determined the frequency of the risk of choking/gagging, food regurgitation or the occurrence of vomiting during a meal in the study groups. Material and method: a cross-sectional survey was conducted among mothers of children from 6 months to 36 months of age residing throughout Poland.ResultsThe study group was divided into three subgroups: mothers using BLW (M-BLW), mothers not familiar with the BLW method (M-NoBLW)), mothers not using the BLW method - mothers using the spoon-feeding method) (M-TS). Among the mothers surveyed, 413 women (63.93%) used the BLW method, 222 mothers (34.36%) did not use the BLW method of which 50 (7.73%) of these were unfamiliar with the method, and 172 (26.62%) simply did not use it. Among M-TS mothers, the child was most often entirely or mostly spoon-fed by an adult (73.84%), and the same was true for the M-NoBLW group (70.0%). In the M-BLW group, 58.60% of children were half-fed by an adult with a spoon. half ate independently.ConclusionsInfants fed by the BLW method were more likely to have their diets expanded after 6 months of age, they were also more likely to be given products from the family table than children fed traditionally with a spoon. Full BLW was implemented by only 29% of children in the BLW group. The vomiting reflex, spitting food out of the mouth, and gagging, were more common among children fed by the BLW method. In contrast, choking occurred comparably often in both groups - in 5.4% of spoon-fed children and 6.9% of BLW-fed children.

Body composition is an important indicator of the overall health and fitness of team sports athletes, including in football, and therefore, anthropometric profiling of elite football players is useful as part of determining their skills, strengths, and weaknesses to develop effective strength and conditioning programs. One of the tools available to coaches to track correlates of performance and health is routine body composition assessment. The purpose of this study is to describe and compare the body composition and anthropometric profiles of players using the Direct Segmental Multi-Frequency Bio-Electrical Impedance Analysis method, and to manage body composition throughout the round in the 2020–2021 season. The investigation was carried out during the Polish football league, PKO BP Ekstraklasa, spring round of the football season 2020–2021, in which male football players participated. Athletes between the ages of 18 and 25 (n = 16) made up the younger age group, while those between the ages of 26 and 31 (n = 22) made up the older age group. This manuscript is a continuation of the presentation of the results of the study, which was conducted between 7 January and 23 July 2021. At different stages of the macrocycle, participants underwent six different body composition analyses. The younger and older groups of athletes were compared, as well as measurements of time points 1–6. The dominant extremities, assisting extremities, and trunk had larger fat-free mass contents in the older age group. In the study groups, there was a difference in the fat-free mass content between measures 1–6 that was statistically significant. In the younger group, there was a statistically significant difference in the amount of fat mass content between measurements 1–6. In the older age group, no statistically significant changes were found. The study showed changes in fat-free mass and fat mass in body segments; differences were observed between age groups and between different moments of measurement. Age is an important factor in determining body composition and is also related to an athlete’s experience and seniority. Anthropometric profiling and comprehensive body composition analysis are important tools used in preparing athletes for competition.

Applied psychopharmacotherapy and psychotherapy do not always bring the expected results in the treatment of mental disorders. As a result, other interventions are receiving increasing attention. In recent years, there has been a surge in research on the effects of nutrition on mental status, which may be an important aspect of the prevention of many mental disorders and, at the same time, may lead to a reduction in the proportion of people with mental disorders. This review aims to answer whether and to what extent lifestyle and related nutrition affect mental health and whether there is scientific evidence supporting a link between diet and mental health. A review of the scientific evidence was conducted based on the available literature by typing in phrases related to nutrition and mental health using the methodological tool of the PubMed database. The literature search yielded 3,473 records, from which 356 sources directly related to the topic of the study were selected, and then those with the highest scientific value were selected according to bibliometric impact factors. In the context of current changes, urbanization, globalization, including the food industry, and changes in people’s lifestyles and eating habits, the correlations between these phenomena and their impact on mental state become important. Knowledge of these correlations creates potential opportunities to implement new effective dietary, pharmacological, therapeutic, and above all preventive interventions. The highest therapeutic potential is seen in the rational diet, physical activity, use of psychobiotics, and consumption of antioxidants. Research also shows that there are nutritional interventions that have psychoprotective potential.

BackgroundOne of tools to tackle growing problem of overweight and obesity are the taxation mechanisms applied to sugar-sweetened beverages, which are expected to influence the common eating behaviors, but also they have impact on the market and public finances. The solution is therefore highly entangled in the complex of social and intersectoral interests generating a number of opportunities and threats affecting its feasibility.AimsThe study aims to depict the views of Polish stakeholders on the implementation of the sugar tax in Poland, particularly the perception of success determinants, barriers, as well as views on the features of the implemented solutions and possible alternatives.MethodsWe used semi-structured interviews with 18 individuals representing key public health stakeholders in Poland. The interview consisted of four parts, where first concentrated on the advantages and disadvantages of the SSB tax, the second part explored stakeholder involvement and stances, third concerned the feasibility of the project, and in the fourth part respondents were asked for suggestions for decision-makers regarding the content of the project and its implementation process. To reconstruct position of 4 main political parties we applied desk research. We used MAXQDA v2020 to analyse the collected data.ResultsStakeholders tend to expressed conflicting views on the effectiveness, relevance and socio-economic impact of the SSB tax. All of them agreed that the tax may appear severe for the poorest groups, children and adolescents, while disagreeing about the economic impact of the levy. The allocation of additional tax revenues was raising doubts, with stakeholders believing that the fiscal aim is the basic reason for implementing the tax, while these resources should be primarily dedicated to health promotion intervention and prevention of diet-related diseases. On the other hand, the political debate on the tax was highly superficial with strong populism arising of the presented positions.ConclusionsThere is a need to conduct a thorough public debate and improvements in terms of public communication to increase social awareness, sealing and refining the implemented solutions. Close cooperation with market players and non-governmental organizations is highly recommended.

The aim of the study was to verify the knowledge of mothers of children under 3 years of age about the Baby Led Weaning (BLW) feeding model and their practical implementation of this method. The study involved 761 mothers and their children. After analysis of the inclusion and exclusion criterion, the information provided by women 699 aged 21–48 years was included in the final data analysis. In the study group, most children were breastfed for 6 months to 1 year (n = 256, 36.7%), 1 year to 2 years (n = 179, 25.6%) and over 2 years (n = 71, 10.2%). Starting dietary expansion before 17 weeks of age was implemented in 47 (6.7%) children, between and 17–26 weeks of age in 328 (46.9%) children, and after 26 weeks of age in 324 (46.3%) children. Feeding food and dishes from the family table was practiced by 518 (74.1%) mothers. Spoon-feeding was practiced by 529 (75.6%) children, 157 (22.4%) children were fed this way sometimes. Taking into account the above data, feeding with the BLW method was used in 170 children (24.2%). In the examined group of mothers the use of the BLW method in feeding their children, especially during diet expansion, was declared by 408 women (74.8%). The child's independent decision concerning what the child will eat and what is according to the BLW method is accepted by 434 (62.1%) mothers. Among the positive aspects of using the BLW method, the women surveyed indicated the child's independence, while among the disadvantages, the omnipresent mess and chaos when eating meals.

Background: The aim of this study was to assess the diet of children with Down syndrome (DS) and to identify potential dietary mistakes made by their parents. Materials and methods: The study was conducted among 195 parents of people with DS between November 2020 and March 2021. Data for the study were collected anonymously using the CAWI method. Results: 122 (62.6%) people with DS did not eliminate any nutrient from their diet. By contrast, in the study group, the following numbers of people reported the following dietary restrictions: 51 (26.2%) gluten, 56 (28.7%) lactose, 17 (8.7%) casein, 26 (13.3%) sucrose, 2 (1.0%) histamine, 2 (1.0%) lectins, and 1 (0.5%) dairy. The most frequent response for vegetable and fruit consumption was once a day, with 83 (42.6%) and 87 (44.6%) parents indicating this. The most frequent response for dairy product consumption was every day, with 72 (36.9%) parents indicating this, while 36 (20%) parents stated that their children do not eat dairy products at all. In the study group, the most frequent response for meat consumption was several times a week, this was indicated by 107 (54.9%) parents, while 1 (0.5%) of them said that their children do not eat meat products at all. The most frequent response for fish consumption was 1–2 times a week, this answer was indicated by 101 (51.8%) parents, while 13 (6.7%) said that their children do not eat these products at all. Conclusions: A majority of the subjects with DS are usually fed in a normal way, but nutritional mistakes are made by the parents. Special attention should be paid to prolonging the period of natural feeding.

Background. The COVID-19 pandemic has become a challenge for the world today, so it is very important to create healthy eating habits in society to support immunity and raise awareness of the benefits of supplementation. Objective. The purpose of this study is to evaluate diet and dietary supplementation, since previous studies indicate the protective nature of these in building immunity during the pandemic and post-pandemic period (COVID-19). The hypothesis of the study is whether the dietary regimen presented by the COVID-19 respondents can be considered protective in building immunity against SARS-CoV-2. Material and methods. The study included 304 subjects, with an average age of 39.04 ± 23.59. The main criteria for inclusion in the study were that the respondent was ≥18 years old and participated voluntarily. The study was conducted using an original questionnaire. Results. In the study group, no change was noticed in the previous diet during the COVID-19 pandemic, while the level of physical activity among the respondents decreased. Too low a percentage of people regularly consumed, among other foods. legume seeds—only 10.5% of respondents consumed them several times a week—and citrus fruits—the largest number of respondents, as many as 39.8%, only consumed them several times a month. The largest percentage of respondents with mild/scanty COVID-19 disease regularly took vitamin C-containing preparations (n = 61; 59.80%). Statistical analysis showed that there was a correlation between the incidence of mild/scanty COVID-19 and the regularity of taking vitamin C-containing preparations (T = 11.374; r = 0.611; p = 0.04603). A statistical significance level was also obtained for the regularity of supplementation of multivitamin preparations, which were taken by 68% (34) of respondents affected by mild/scanty COVID-19 (T = 13.456; r = 0.711; p = 0.02191). Conclusions. The study’s hypothesis was supported. Respondents characterized by a normal dietary pattern and taking supplements commonly recognized as immune “boosters” were more likely to mildly survive COVID-19. Moreover, it was shown that the pandemic in most of the respondents did not significantly affect their dietary strategy. It is reasonable to conclude that the dietary patterns adopted may be a common way to prevent SARS-CoV-2 infections and their possible complications.

Introduction: Hybrid ablation (HABL) of atrial fibrillation combining endoscopic, minimally invasive, closed chest epicardial ablation with endocardial CARTO-guided accuracy was introduced to overcome the limitations of current therapeutic options for patients with persistent (PSAF) and longstanding persistent atrial fibrillation (LSPAF). The purpose of this study was to evaluate the procedural safety and feasibility as well as effectiveness of HABL in patients with PSAF and LSPAF 1 year after the procedure. Material and methods : The study is a single-center, prospective clinical registry. From 07/2009 to 12.2014, 90 patients with PSAF (n = 39) and LSPAF (n = 51), at the mean age of 54.8 ±9.8, in mean EHRA class 2.6, underwent HABL. 64.4% of patients had a history of prior cardioversion or catheter ablation. Thirteen patients had LVEF less than 35%. Mean AF duration was 4.5 ±3.7 years. Patients were scheduled for 3-, 6- and 12-month follow-up with 7-day Holter monitoring. Results : At 6 months after the procedure 78% (54/69) of patients were in SR. At 12 months after the procedure 86% (59/69) were in SR and 62.3% (43/69) in SR and off class I/III antiarrhythmic drugs (AADs). Only 1% (1/69) of patients required a repeat ablation for atrial flutter. A significant decrease in LA dimension and an increase in LVEF were noted. Conclusions : A combination of epicardial and endocardial RF ablation should be considered as a treatment option for patients with persistent and long-standing persistent atrial fibrillation as it is safe and effective in restoring sinus rhythm.
