Adipose Dysfunction Indices as a Key to Cardiometabolic Risk Assessment-A Population-Based Study of Post-Myocardial Infarction Patients.

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.

Comparison of Nutrition among Female Floorball Players of Extra-Class Teams from Poland and the Czech Republic during the Preparation Period for the League Season.

The study aimed to assess the frequency of food intake and to compare the consumption of female extramural players training floorball in Poland and the Czech Republic during the preparation period for the league season. In total, 43 players training floorball in senior clubs participated in the study, including 21 from the Polish and 22 from the Czech clubs. The research tool was based on the standardised questionnaire for the Examination of Eating Behaviours and Opinions on Food and Nutrition (QEB). The study also analysed body composition using the Bioelectrical Impedance Analysis (BIA) method, and the research tool was a TANITA MC-780 S MA body composition analyser (Tanita Corporation, Tokyo, Japan). The Polish women's floorball players had lower results in body fat percentage (FM) and muscle mass (MM) than the Czech team. The mean FM in the players of the Polish team was 18.6% ± 5.4, and the mean MM was 45.8 kg ± 4.2. In the Czech team players, these figures were 19.8% ± 5.4 and 47.8 kg ± 4.2. Despite the similar value of mean BMI in both teams, the highest BMI in the case of female athletes from Poland (17.7), indicating underweight, and the highest BMI in female athletes from the Czech Republic (26.9), indicating overweight, were significant. The study showed differences in both body composition analysis and dietary patterns of the Czech and Polish players. The Czech women's floorball players had a higher muscle mass and body fat percentage than Polish floorball players. Furthermore, differences in diet were observed among the players of the Czech team compared to the players of the Polish team. The Czech women's floorball players consumed a slightly higher amount of healthier products, such as whole-grain products. The Polish players took in more meat, processed products and fruit juices. This study is one of the first to assess the nutrition of those involved in floorball. There is a need for further research that focuses on the specifics of the discipline, the exercise capacity of the players and points during the season that require nutritional support. This knowledge would help develop effective nutritional strategies and plan and implement appropriate nutrition education for this group of athletes.

Infant Complementary Feeding Methods and Subsequent Occurrence of Food Neophobia-A Cross-Sectional Study of Polish Children Aged 2-7 Years.

Food neophobia is standard behaviour in child development. It is a complex process and occurs to varying degrees. The symptoms of neophobia can be variable depending on the individual. Food neophobia is a fear of new foods, whereby difficulties in eating and trying unfamiliar foods follow. It is one of the more vital determinants of the number of meals consumed at a young age. Such a process is not a disorder in itself but can lead to one. The highest severity of neophobia occurs between the ages of two and six, but in some children, it lasts beyond age 6. This study aimed to assess the prevalence of food neophobia among children aged 2-7 years, taking into account the method of complementary feeding, the length of breastfeeding, exclusive breastfeeding, the period of introduction of complementary foods, and the use of the BLW method during the period of dietary expansion. MATERIALS AND METHODS: The study used an anonymous survey questionnaire consisting of five parts as the research tool. The first part of the questionnaire was a metric and concerned the socio-demographic data of the parent/guardian and their child. A standardised questionnaire assessing food neophobia among children was used to assess food neophobia: the Food Neophobia Scale-Children (FNSC). RESULTS: In the study group, 171 children (29.23%) had a low risk of food neophobia according to the FNSC, 182 children (31.11%) had a medium risk of neophobia, and 232 children (39.66%) had a high risk of neophobia. A correlation was observed between the age and the risk of food neophobia (p = 0.0002). Statistically significant differences were found between children aged 2 and 4 (p = 0.003) and children aged 2 and 5 years (p = 0.049). We observed no correlation between gagging (p = 0.88557), choking (p = 0.17597), and needing medical intervention (p = 0.61427) and the risk of associated neophobia. CONCLUSION: In the study group of children, the highest risk of food neophobia was characterized by children aged 4, 5, and 7 years. The length of breastfeeding and exclusive breastfeeding did not affect the risk of food neophobia. In the month in which complementary feeding (CF) was introduced, the children were fed using the baby-led weaning method (BLW method), and introducing puree and puree with lump food into the children's diet also did not affect the risk of food neophobia. It was shown, however, that children whose mothers observed difficulties during CF and whose children had a vomiting reflex and spat food out of their mouths during CF were more likely to develop food neophobia at the preschool age.

Predictors of ventricular tachyarrhythmia in patients with implantable cardioverter-defibrillator and non-ischemic systolic heart failure.

BACKGROUND: The benefit derived from implantable cardioverter-defibrillators (ICD) in subjects with non-ischemic systolic HF (NICM) is less well-established. AIM: The study aimed to determine the incidence, predictors, and prognostic impact of ventricular arrhythmias in patients with ICD and NICM. METHODS: The study sample included 377 consecutive patients with ICD or cardiac resynchronization cardioverter-defibrillators (CRT-D, 74% of patients) and NICM implanted and monitored remotely in a university hospital. RESULTS: During the median (interquartile range [IQR]) follow-up of 1645 (960-2675) days, sustained ventricular arrhythmia occurred in 92 patients (24.4%). Of those, ventricular fibrillation (VF), ventricular tachycardia (VT), and both VT and VF occurred in 10 (10.9%), 72 (78.3%), and 10 (10.9%) patients, respectively. Patients with vs. those without ventricular arrhythmia differed concerning sex, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction (LVEF), post-inflammatory etiology, atrial fibrillation/flutter occurrence, and supraventricular arrhythmia (SVT) other than AF/AFL during follow-up. In multivariable Cox regression, LVEDD (hazard ratio [HR], 1.05; 95% confidence interval [CI], 1.003-1.09; P = 0.03), AF/AFL (HR, 1.86; 95% CI, 1.21-2.85; P = 0.004), and SVT (HR, 1.77; 95% CI, 1.10-2.87; P = 0.02) were independent predictors of sustained VT, while AF/AFL (HR, 1.65; 95% CI, 1.07-2.56; P = 0.02) was independent predictor of VF. All-cause mortality in patients with VT/VF was significantly higher than in subjects without sustained ventricular arrhythmias (35.9% vs. 22.4%; P = 0.01). CONCLUSIONS: Ventricular arrhythmia occurred in every fourth patient with NICM and ICD during 4.5 years of observation and was associated with significantly worse prognosis than in subjects free of VT/VF. Higher LVEDD, atrial fibrillation/atrial flutter, and supraventricular tachycardia flag patients at risk of ventricular arrhythmia.

Lifestyle and the risk of acute coronary event: a retrospective study of patients after myocardial infarction.

Introduction: Unhealthy 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 methods: The 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). Results: Most 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%). Conclusion: The 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.

Analysis of public food procurement in relation to dairy products and their quality criteria.

Introduction: Public 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 methods: A 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). Results: Criteria 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. Conclusion: Introducing 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.

Anthropometric Profiling and Changes in Segmental Body Composition of Professional Football Players in Relation to Age over the Training Macrocycle.

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.

Prevalence of Feeding Problems in Children and Associated Factors-A Cross-Sectional Study among Polish Children Aged 2-7 Years.

Food neophobia is an aversion to eating or a reluctance to try unfamiliar or new foods. From an evolutionary perspective, this behaviour may minimise the risk of consuming foods that are harmful to health. However, such aversion causes food monotony, which may result in nutritional deficiencies. This study aimed to assess the prevalence of feeding problems among Polish children aged 2-7 years using the Montreal Children's Hospital Feeding Scale and to investigate the correlation between age, gender, mode of feeding in infancy, including complementary feeding, and the prevalence of feeding difficulties in the study group of children. MATERIAL AND METHOD: The study group consisted of 585 children: 299 boys (51.11%) and 286 girls (48.89%). The study was conducted using a questionnaire-based method, with an indirect survey technique using a web-based form (CAWI). The research tool used was the Montreal Children's Hospital-Pediatric Feeding Program. RESULTS: Groups with the lowest risk feeding problems, risk 0, comprised 445 children (76.06%); group 1, middle difficulties, 59 children (10.08%); group 2, moderate difficulties, 40 children (6.84%); and group 3, most difficulties, 40 children (7.01%). The mean MCH-FS score for the entire study group was calculated and was 37.29 points ± 12.02; for 2 year olds, 35.69 points; for 3 year olds, 37.41 points; for 4 year olds, 38.31 points; for 5 year olds, 38.46 points; for 6 year olds, 37.95 points; and for 7 year olds, 36.06 points. The mean value of the MCH-FS scale for girls was 37.44 points, and for boys, 37.32 points. None of the above parameters correlated with the risk of feeding problems, including age, except with a non-significative tendency to be higher in the youngest age. CONCLUSION: Breast milk feeding and the time of complementary feeding (CF) in the study group did not influence the risk of feeding problems. Using the full BLW method during CF can protect the child against the occurrence of feeding problems such a food selectivity or picky eating in the future. In our study, children with difficulties during CF, mainly the vomiting reflex, were more likely to develop feeding problems such as food neophobia. Based on our study, we did not observe a correlation between age, gender, and the occurrence of feeding problems, and there was only a non-significant tendency to be higher in the youngest age. However, further research needs to be undertaken to assess how such behaviour affects subsequent feeding difficulties.

Diet in Patients with Myocardial Infarction and Coexisting Type 2 Diabetes Mellitus.

BACKGROUND: Dietary modifications are recommended alongside pharmacotherapy in treating both diabetes mellitus (DM) and coronary heart disease (CHD) patients. AIMS: The primary aim of our study was to assess the diet in patients with type 2 diabetes mellitus (T2DM) and myocardial infarction (MI) and to identify dietary differences between patients after the first and subsequent cardiovascular (CV) event. The secondary aim was to analyze the differences between men's and women's diets. METHODS: The study population consisted of patients with DM/T2DM and MI. The research tool was the original author's questionnaire which was collected personally by a qualified dietician. RESULTS: The study included 67 patients with a mean age of 69 ± 8 years, hospitalized at the Silesian Centre for Heart Diseases in Zabrze in 2019. The study found that patients consumed less bread, whole-grain cereal products, fermented milk products, and vegetables than was recommended. A total of 32.8% of patients reported an intake of sweetened beverages, while 85.1% of participants consumed sweets despite being diagnosed with DM. Except for sweetened drinks, no differences in dietary behaviors were found in the patients after the first and second MI episode. Most of the included patients assessed their diet as appropriate. CONCLUSION: The dietary assessment of diabetes and myocardial infarction patients indicates that the diet does not comply with dietary recommendations, thus increasing the risk of a recurrent cardiac event despite a previous MI. No differences between the men's and the women's nutritional habits were observed.

Flecainide in clinical practice.

Flecainide, similar to encainide and propafenone, is IC class antiarrhythmic, inhibiting Nav1.5 sodium channels in heart muscle cells and modulates cardiac conduction. Despite its over 40-year presence in clinical practice, strong evidence and well-known safety profile, flecainide distribution in Europe has not always been equal. In Poland, the drug has been available in pharmacies only since October this year, and previously it had to be imported on request. Flecainide can be used successfully in both the acute and chronic treatment of cardiac arrhythmias. The main indication for flecainide is the treatment of paroxysmal supraventricular tachycardias, including atrial fibrillation, atrioventricular nodal re-entrant tachycardia, atrioventricular re-entrant tachycardia and ventricular arrhythmias in patients without structural heart disease. Beyond that, it may be used in some supraventricular tachycardia in children and for sustained fetal tachycardia. Many studies indicate its efficacy comparable to or better than previously used drugs such as propafenone and amiodarone, depending on the indication. This review aims to highlight the most important clinical uses of flecainide in the light of the latest scientific evidence and to provide an overview of the practical aspects of treatment, including indications, off-label use, contraindications, areas of use, monitoring of treatment and most common complications, taking into account special populations: children and pregnant women.

The Assessment of Body Composition and Nutritional Awareness of Football Players According to Age.

The optimal body composition for health is an individual trait and is determined by genetic factors, sex, age, somatotype, physical activity, and individual variability. The present study aims to assess how professional football players' body composition has changed over the training macrocycle in various age groups and to determine the correlation between nutritional awareness and body composition maintenance. Thirty-eight football players participated in the study, with 16 players classified in the younger age group (19-25) and 22 in the older age group (26-31). Using the direct segmented multi-frequency electrical impedance analysis technique, the athletes' body composition was assessed six times across a training macrocycle made up of preparatory, competitive, and transitional periods. The Sports Nutrition Knowledge Questionnaire was used to evaluate nutrition knowledge. The above correlations show that both younger and older athletes with higher awareness are better able to adjust their nutrition to meet the goals of the preparation period and can achieve greater gains in muscle mass and greater reductions in body fat. According to the study's results, athletes who are better conscious of their nutritional needs during competition experience less muscle loss and exhibit more consistent body weight and BMI levels. Football players' body composition suffers detrimental alterations throughout the transition period. Higher body mass, lean body mass content, and skeletal muscle mass are traits of older players. Higher nutritional knowledge reduces the negative modifications of body composition consisting of muscle mass reduction and fat gain. Nutritional knowledge influences the stability of body composition in both age groups during all the analyzed periods: Preparation, competition, and transition.

Complementary Feeding Methods, Feeding Problems, Food Neophobia, and Picky Eating among Polish Children.

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.

Changes in body composition during the macrocycle of professional football players in relation to sports nutrition knowledge.

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.

Proper Dietary and Supplementation Patterns as a COVID-19 Protective Factor (Cross-Sectional Study-Silesia, Poland).

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.

Traditional complementary feeding or BLW (Baby Led Weaning) method? - A cross-sectional study of Polish infants during complementary feeding.

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. Results: The 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. Conclusions: Infants 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.

The implantation of AV leadless pacemaker - a case report.

In early 2020 Food and Drug Administration (FDA) approved Micra AV - a new type of leadless pacemaker with atrioventricular synchrony, to treat patients with atrio-ventricular (AV) blocks. We describe one of the first in Poland case of a patient who was implanted with Micra AV pacemaker. CASE REPORT: A 38-year-old female patient was admitted to the clinic due to the 29-seconds event of a complete AV block without an escape rhythm and was implanted with a dual chamber pacemaker without any complications. After several months she was admitted again with suspicion of ventricular perforation by the pacemaker electrode and underwent a replacement procedure of both pacemaker's leads. Nevertheless, one week later the patient developed a fever with significantly elevated inflammatory markers. The blood cultures were negative but in the transesophageal echocardiography features of cardiac device-related infective endocarditis were observed. Empirical antibiotic therapy was administered, and the device was removed. The Heart Team qualified the patient for the implantation of a MicraTM AV leadless pacemaker. The procedure was performed without any complications and the device was implanted to the right ventricle. All parameters were correct, and the patient was discharged. CONCLUSIONS: Micra AV may be a feasible and safe option for young patients with paroxysmal AV block after device-related complications.

Body Composition and Its Perception among Professional Female Volleyball Players and Fitness Athletes (Silesia, Poland).

Female athletes experience both sociocultural and sport-specific pressures of an ideal body and appearance and are vulnerable to dissatisfaction with their bodies. Among sport-specific pressures, the type of sport is a predictor of body image dissatisfaction. The study included 150 females: 50 volleyball players, 50 bodybuilding and fitness athletes, and 50 female students, who were the control group. Body composition and perception and evaluation of one's own body were assessed. BMI was similar in the study group of female athletes and the control group, but the bodybuilding and fitness athletes had the lowest body fat, while the control group had the highest. Perception of one's own body in the aspect of the evaluation of specific body parts was highest among bodybuilding and fitness athletes, while in the aspect of body condition, the best results were obtained by volleyball players. Most female volleyball players were dissatisfied with their current body weight, as were women in the control group, in contrast to female bodybuilding and fitness athletes, who were most often satisfied with their current body weight.
