Influence of physician and clinical dietitian on the use of dietary supplements among Polish patients with ulcerative colitis – pilot study / Influencia del médico y dietista clínico sobre el uso de suplementos dietéticos entre pacientes polacos con colitis ulcerosa – estudio piloto

Introduction: Patients with ulcerative colitis are a group of patients who are particularly vulnerable to nutritional deficiencies. Supplementation, prescribed by a physician or clinical dietitian, is therefore important in these patients. Materials and methods: The study was carried out by means of a questionnaire on a group of 106 people diagnosed with colitis and in remission. Results: More than 92% recommended the use of dietary supplements. Vitamin supplements were most common among people with ulcerative colitis (82.7%). The physician as a source of knowledge positively influenced the use of vitamin and mineral supplements (r=0.23, p=0.0213) while dietitians as a source of knowledge showed no significant effect on patients' supplementation choices. Conclusion: In Poland, the physician is the main source of supplementation knowledge than the clinical dietitian. This may be due to the unregulated nature of the dietitian profession in the Polish health care system. . It is therefore necessary to integrate dietitians in Poland into the medical profession, which will allow for better results in the treatment of not only IBD patients.(AU)

In Vitro Evaluation of Bioavailability of Cr from Daily Food Rations and Dietary Supplements from the Polish Market.

Only some of the nutrients consumed with food are able to be absorbed from the gastrointestinal (GI) tract and enter the systemic circulation (blood). Because some elements are essential minerals for humans, their beneficial effect on the body depends significantly on their bioavailable amount (the fraction that can be absorbed and used by the organism). The term bioavailability, which is very often used to describe the part of nutrients that is able to be absorbed, is influenced by various factors of exogenous and endogenous origin. The main purpose of the study was to assess the relative bioavailability of Cr from selected dietary supplements in the presence of various types of diets, which significantly influence the level of bioavailability. The research was performed using a previously developed and optimized two-stage in vitro digestion model using cellulose dialysis tubes of food rations with the addition of pharmaceutical products. Cr was determined using the ICP-OES and GF-AAS methods, depending on its concentration in particular fractions. The determined relative bioavailability ranged between 2.97 and 3.70%. The results of the study revealed that the type of diet, the chemical form of the molecule, and the pharmaceutical form of preparations have a significant influence on the bioavailability of Cr.

Ceratophyllum demersum the submerged macrophyte from the mining subsidence reservoir Nadrybie Poland as a source of anticancer agents.

Aquatic plants are a rich source of health-beneficial substances. One of such organisms is the submerged macrophyte Ceratophyllum demersum, which has not been sufficiently studied in this aspect so far. In this work, we have studied environmental conditions prevailing in a subsidence mining reservoir in Eastern Poland and shown that C. demersum can be harvested for further analysis even from artificial anthropogenic reservoirs. The phytochemical analysis of C. demersum ethanolic extract using LC-MS revealed high content of phenolic compounds (18.50 mg/g) (mainly flavonoids, 16.09 mg/g), including those that have not yet been identified in this plant, namely isorhamnetin, sakuranetin, taxifolin, and eriodictyol. Such rich flavonoid content is most likely responsible for the anticancer activity of the C. demersum extract, which was targeted especially at neoplastic cells of gastrointestinal tract origin. The flow cytometry analysis of treated cells showed an increased percentage of late apoptotic and necrotic cells. The fish embryo toxicity (FET) test showed safety of the extract towards Danio rerio fish up to the concentration of 225 µg/ml. This study has shown that the submerged macrophyte Ceratophyllum demersum can be taken into consideration as a rich source of a set of anticancer agents with chemopreventive potential.

Nutrition of Newborns with Hypoxic-Ischaemic Encephalopathy during Therapeutic Hypothermia - A Survey of Practice in Polish Neonatal Care Units.

BACKGROUND: The nutritional practice for newborns with hypoxic-ischaemic encephalopathy during therapeutic hypothermia differs among Polish neonatal care units, as no guidelines are provided. We assessed the prevailing procedures. MATERIAL AND METHODS: Data was collected through an anonymous, web-based questionnaire. We surveyed aspects of the current nutritional practices and the reasoning behind the choice of the feeding strategy. RESULTS: Thirty-one responses were obtained (31/33, 94%). Based on participants' estimations, 342 newborns are diagnosed with hypoxic-ischaemic encephalopathy and qualified for therapeutic hypothermia annually. Among them, almost ⅓ is fed exclusively parenterally, while 71% both ways-parenterally and enterally. In the vast majority of units, the introduction of enteral nutrition takes place during the first 48 hours of therapeutic hypothermia, and breast milk is primarily provided, although with substantial first feeding volume differentiation (an average of 2,9 ml/kg (0,3 - 10ml/kg)). Adverse events, such as necrotising enterocolitis, sepsis, and glycemia level disturbances that derive from the initiation of enteral nutrition, are difficult to estimate as no official statistics are provided. CONCLUSIONS: The majority of newborns after hypoxic-ischaemic encephalopathy treated with therapeutic hypothermia are fed both parenterally and enterally during the procedure, predominantly with expressed or donor breast milk. However, due to the lack of nutritional guidelines, significant variability of nutritional strategies concerning initiation time, type and volume of enteral feeds given is noted. Therefore, further studies are required to clarify feeding recommendations.

Analytical Assessment of the Antioxidant Properties of the Coneflower (Echinacea purpurea L. Moench) Grown with Various Mulch Materials.

Antioxidants are added to foods to decrease the adverse effect of reactive species that create undesirable compounds that destroy essential nutrients and, therefore, lower the nutritional, chemical and physical properties of foods. This study was carried out to determine the antioxidant properties of flowers and plant stems with leaves of Echinacea purpurea grown with mulches of different colours and thicknesses. Coneflowers were grown in the Experimental Station of the Agricultural University in Kraków, Poland. The mulching materials used were black, green and brown colours of 100 g/m2 and 80 g/m2 density. In plant material, e.g., flowers or plant stems plus leaves the proximate analysis, the total polyphenol content and the ability to scavenge free radicals (ABTS, DPPH and FRAP) were determined. The results show that flower samples had a higher content of compound proteins, ash and phenolic compounds. The mulching colour and density did not affect the proximate analysis of the E. purpurea plant. Based on the result of this study, E. purpurea is a potential source of natural antioxidants and can be used to improve the antioxidant activity of various food products as well as in cosmetics within the pharmaceutical industry.

Negative Association of Lignan and Phytosterol Intake with Stress Perception during the COVID-19 Pandemic-A Polish Study on Young Adults.

BACKGROUND: There has been an increasing global prevalence of depression and other psychiatric diseases in recent years. Perceived stress has been proven to be associated with psychiatric and somatic symptoms. Some animal and human studies have suggested that consuming foods abundant in lignans and phytosterols may be associated with lower levels of stress, depression, and anxiety. Still, the evidence is not yet strong enough to draw firm conclusions. Thus, we investigated the association between dietary intake of these phytochemicals and the level of stress experienced by adult individuals. METHODS: Diet was assessed using self-reported 7-day dietary records. The intakes of lignans and phytosterols were estimated using databases with their content in various food products. The Perceived Stress Scale (PSS) was implemented to measure the level of perceived stress. A logistic regression analysis was used to test for associations. RESULTS: The odds of elevated PSS were negatively associated with dietary intake of total phytosterols, stigmasterol, and ß-sitosterol, with evidence of a decreasing trend across tertiles of phytochemicals. The analysis for doubling the intake reinforced the aforementioned relationships and found protective effects against PSS for total lignans, pinoresinol, and campesterol. CONCLUSIONS: Habitual inclusion of lignans and phytosterols in the diet may play a role in psychological health. To address the global outbreak of depression and other mental health issues triggered by stress, it is important to take a holistic approach. There is a need to develop effective strategies for prevention and treatment, among which certain dietary interventions such as consumption of products abundant in lignans and phytosterols may play a substantial role.

Breastmilk mineral composition among well-educated mothers from Central Poland - Associations with maternal dietary intake, dietary patterns and infant psychomotor development.

BACKGROUND: Maternal dietary habits could affect breastmilk mineral composition, which may influence infant development. Mineral dietary intake or supplementation slightly affects its breastmilk concentration. However, the intake of selected food groups or dietary patterns that reflect diet complexity could have a greater impact. Hence, the aim of the study was to assess breastmilk mineral composition at one, three, and six months of lactation among mothers living in urban area of Central Poland, as well as the evaluate maternal dietary determinants and associations with infant anthropometric and psychomotor development. METHODS: The study was conducted among 43 healthy and exclusively breastfeeding mothers. In the first, third, and sixth months of lactation, we collected breastmilk samples and assessed the concentration of Ca, P, Zn, Fe, Se, Ni, As, Pb, and Cd using the ICP-MS method. Maternal dietary habits were evaluated by a food frequency questionnaire in the first month of lactation, whereas in the third and sixth by the three-day food record. Based on the collected data adherence to the Polish-adapted Mediterranean (Pl-aMED; 1 month) and the DASH diet (Mellen's Index; 3 and 6 months) was assessed. In the third and sixth months of lactation infant anthropometric parameters and the sixth month of lactation psychomotor development were evaluated. RESULTS: Breastmilk Se, Ni, As, Pb, and Cd levels were under the LOQ in all the breastmilk samples at all study visits. Median breastmilk mineral concentrations of Ca, P, Zn, and Fe in the first, third, and sixth months of lactation varied from 381.9 to 332.7 mg/L, 161.6 to 139.1 mg/L, 2.2 to 0.8 mg/L, and 0.26 to 0.17 mg/L, respectively. Maternal dietary intake and supplementation did not affect breastmilk Ca, P, Zn, and Fe. Pl-aMED scores were associated with breastmilk Ca (ß = 0.489, 95% CI 0.180 - 0.799, p = 0.003) and Zn (ß = 0.499, 95% CI 0.199 - 0.798, p = 0.002) in the first month of lactation, whereas no association with the DASH diet were observed in the third and sixth month of lactation. Breastmilk Fe in the third month was associated with infant motor development (ß = 0.420, 95% CI 0.113 - 0.727, p = 0.009) in the sixth month of life, but no other associations with anthropometric or psychomotor development were observed. Moreover, we estimated that few infants meet their adequate intake (AI) requirements for P, Zn, and Fe. CONCLUSION: Our study showed that maternal adherence to Pl-aMED is a significant predictor of breastmilk Ca and Zn in the first month of lactation, which may be especially important considering that more than 75% of infants had inadequate Zn intake. Moreover, we found that breastmilk Fe positively influenced infant motor development, despite the majority of infants having inadequate intake. On the other hand, no infant had deficiency symptoms, which emphasizes the necessity to evaluate of AI norms for infants.

In Silico Safety Assessment of Bacillus Isolated from Polish Bee Pollen and Bee Bread as Novel Probiotic Candidates.

Bacillus species isolated from Polish bee pollen (BP) and bee bread (BB) were characterized for in silico probiotic and safety attributes. A probiogenomics approach was used, and in-depth genomic analysis was performed using a wide array of bioinformatics tools to investigate the presence of virulence and antibiotic resistance properties, mobile genetic elements, and secondary metabolites. Functional annotation and Carbohydrate-Active enZYmes (CAZYme) profiling revealed the presence of genes and a repertoire of probiotics properties promoting enzymes. The isolates BB10.1, BP20.15 (isolated from bee bread), and PY2.3 (isolated from bee pollen) genome mining revealed the presence of several genes encoding acid, heat, cold, and other stress tolerance mechanisms, adhesion proteins required to survive and colonize harsh gastrointestinal environments, enzymes involved in the metabolism of dietary molecules, antioxidant activity, and genes associated with the synthesis of vitamins. In addition, genes responsible for the production of biogenic amines (BAs) and D-/L-lactate, hemolytic activity, and other toxic compounds were also analyzed. Pan-genome analyses were performed with 180 Bacillus subtilis and 204 Bacillus velezensis genomes to mine for any novel genes present in the genomes of our isolates. Moreover, all three isolates also consisted of gene clusters encoding secondary metabolites.

From the name to the popular image of the plant: the Polish names for the black elder (Sambucus nigra).

The names of plants convey information on their appearance (shape, structure, colour), taste or smell, their uses (practical, ceremonial, magical and medicinal) as well as the beliefs and convictions associated with them. Assuming that the particular features of plants, entrenched in their names, must have been important to language users for some reason, the analysis of plant names can help reconstruct traditional knowledge about plants. The author analyses the standard and dialectal names for the black elder (Sambucus nigra) in Polish, juxtaposing the plant's features revealed in its names (linguistic data) with the cultural accounts associated with the plant ("with-linguistic" data). This allows for the reconstruction of the following features of the plant: (a) the appearance of the shrub, (b) the properties of its fruit, (c) the smell of the plant, (d) the place where it grows, (e) the time of harvesting, (f) its use in folk medicine and (g) the association of the plant with impure powers and diseases. The conducted analyses show that reaching for hard "linguistic evidence" (standard and folk names) makes it possible to compile hierarchies of the characteristics of the plants described. Situating these names against the background of "with-linguistic" data leads to the conclusion that folk nomenclature and folk knowledge enrich and complement each other. The vast number of names for the black elder with different onomasiological bases, presenting different points of view, also demonstrate the relationship between the degree of lexical differentiation and the cultural meaning of the plant. The ethnolinguistic analysis of the names for the black elder (Sambucus nigra), similarly to ethnobotanical studies of folk plant names, provides insights into past and contemporary uses of the plant. Thus, it can provide a starting point for further ethnobotanical research.

The Control and Comprehensive Safety Assessment of Heavy Metal Impurities (As, Pb, and Cd) in Green Tea Camellia sinensis (L.) Samples (Infusions) Available in Poland.

Tea is the world's most common drink after water, and the world's annual sales exceed $43 billion, of which more than $11 billion is green tea (Camellia sinensis (L.)). Increasing evidence continues to show that green tea consumption and its ingredients have a variety of potential health benefits. The aim of the study was to control and assess the toxicological risk (TRA) of three heavy metals (As, Pb, and Cd) in infusions of green tea (n = 12) from Polish markets. We applied the method of inductive coupled plasma mass spectrometry (ICP-MS) to determine the selected heavy metal and designed a specific toxicological risk assessment with three crucial tiers. The first tier of our strategy was to determine the elements investigated (heavy metal impurities, µg/L). The second step was to estimate the weekly intake of green tea infusions (µg/week) based on weekly consumption. The third tier was to estimate the weekly intake per weight (µg/L/week/bw), based on the average weekly intake of green tea infusion per adult compared to the provisional weekly intake (PTWI) established by the FAO/WHO Joint Food Additives Expert Committee (JECFA). The levels of the investigated heavy metals occur at different levels in all of the investigated green tea infusions. The heavy metal profile indicated that As (0.0721-10.585 µg/L), Pb (0.386-1.695 µg/L), and Cd (0.126-0.346 µg/L) were present in all samples. Basic analysis of general content shows that As (average = 0.325 µg/L) was at a level similar to Cd (average = 0.214 µg/L). Surprisingly, the Pb content (average 0.891 µg/L) was approximately 2.75-4 times higher than that of As and Cd, respectively. The application of our proposed safety assessment methodology (three tiers) provides satisfactory results for regulatory purposes. The evaluation of the investigated heavy metals in all products analysed from green tea samples (infusions) showed that there were no health hazards to consumers due to weekly exposure. The results indicated that after drinking green tea infusions from Polish markets, the amount of investigated elements in weekly doses does not represent any health risks to consumers.

The toxicological analysis of lead impurities in traditional herbal medicinal product with Thymi herba (Thymus vulgaris L. and Thymus zygis L.) from pharmacies in Poland: the impurity profile and comprehensive toxicological risk assessment.

Traditional herbal medicinal products (THMP) with Thymi herba (Thymus vulgaris L. and Thymus zygis L.) are very popular among the European population. The idea of our study was the toxicological analysis of lead impurities in THMP with Thymi herba obtained from Polish pharmacies. For this purpose, we prepared the impurity profiles and comprehensive toxicological risk assessment. The Pb impurity profiles show lead impurities in all samples investigated (in the range: 2.15-6.99 µg/L). The estimations of Pb impurities in the single dose (32.25-105.01 ng/single dose) and in the daily dose (64.50-210.00 ng/day) were based on the posology recommended by the manufacturers. All the results obtained meet the standards of the ICH Q3D (R1) guideline on elemental impurities according to the levels of Pb. It can be concluded that all investigated THMPs with Thymi herba available in Poland should not represent any health risk to adults.

Promoting whole person health: Exploring the role of traditional Chinese medicine in Polish healthcare.

Poland has a unique history of traditional Chinese medicine (TCM) dating back to the 17th century when Polish missionary Michael (Michal) Boym was a pioneer in the field. In the 20th century, his successor, Professor Zbigniew Garnuszewski, reintroduced acupuncture to medical practice in Poland. However, other methods of TCM and its holistic approach to patient care have not found their place in modern medicine in Poland. At present, the legal status of TCM in Poland remains unregulated, with TCM included in the broad spectrum of complementary and alternative medicine (CAM) practices. Few reports are available on the use of TCM methods among the Polish population. Integrative medicine combines conventional medicine with evidence-based CAM interventions and considers all aspects of a patient's health, including physical, emotional, mental, social, and environmental factors. An integrative healthcare model that incorporates TCM modalities and lifestyle recommendations as well as a whole person approach may provide a more sustainable solution for the constantly underfinanced Polish healthcare system, which faces challenges of multimorbidity in an aging society and limited access to care. The coronavirus disease 2019 pandemic, war in Ukraine, and ongoing climate crisis have underscored the need to strengthen the resilience of the Polish healthcare system and search for new solutions. A model of care that blends the best of biomedicine and TCM healing approaches may be a better option for both patients and the healthcare system in Poland.

Biostimulants and herbicides a tool to reduce non-commercial yield tubers and improve potato yield structure.

The basis for the study was a field experiment conducted in 2012-2014 in the production fields of multi-branch Soleks company in Wojnów, the district of Siedlce in eastern Poland. The experiment was established in a split-plot arrangement as a two-factor experiment in three replications. The first factor were: three cultivars of edible potato-Bartek, Gawin, Honorata, and the second factor were: five objects of potato cultivation with herbicides and biostimulants: 1-Control object-without chemical protection, 2-herbicide Harrier 295 ZC, 3-herbicide Harrier 295 ZC + biostimulant Kelpak SL, 4-herbicide Sencor 70 WG, 5-herbicide Sencor 70 WG + biostimulant Asahi SL. The aim of the study was to reduce the non-commercial potato yield and improve the yield structure through the application of biostimulants and herbicides, and to determine the relationship between weed infestation and tuber yield. The least amount of weeds and the best destruction efficiency were obtained after the application of herbicide Sencor 70 WG + biostimulant Asahi SL and herbicide Harrier 295 ZC + biostimulant Kelpak SL. Effective reduction of weed infestation contributed to improvement of yield structure and reduction of potato non-commercial yield. Based on correlation coefficients, a significant relationship between weed infestation and potato non-commercial yield was shown.

Investment in the peace of mind? How private services change the landscape of maternity care in Poland.

For over two decades midwifery research advocated for the continuity of care and the ability to establish a relationship between care providers and care users as an important features of quality maternity services. In many countries, while unavailable through public services, continuity of care became commercialized and can be access as a private service. In Poland, private prenatal consultations and dedicated midwifery care allow women to access continuity and establish personal relationships with care providers. In this study, we explore, how accessing these private services, impact the rates of medical interventions and type of care women receive during labour and birth. We analyse data collected through an online questionnaire from 4402 first-time mothers in healthy pregnancy who had given birth in Poland between 2020 and 2021. We show that while private consultation did not translate into any significant differences in care, women who accessed private dedicated midwifery services experienced more attentive and less medicalized care, namely were more likely to give birth in vertical position, move freely during labour and less likely to experience emergency caesarean section. However, private dedicated midwifery care did not shield them from negative experience. While private care offers benefits for women who can afford it, it also contributes to inequalities in access to quality care and puts women with less social and financial resources in a vulnerable position. Efforts should be made to develop a more universal and equitable model of care that allows for building personal relationships between maternity care providers and women.

Floodplain lakes as an indicator of increasing industrial pollution - Case study from a fertilizer factory in Poland.

Despite the development of organic farming, the demand for mineral fertilizers is still high. Processes of fertilizer production are water-consuming, which is why factories are often located near large rivers. Such facilities should be monitored in detail because they might pose a threat to water quality. The aim of this study was to analyse the impact of a nitrogen fertilizer factory chemical wastewater treatment plant (CWTP) on the water quality of nearby river-lake systems. Potential contamination could indicate installation defects. Six floodplain lakes were selected for analysis: three located within the embanked area and three outside the embanked area, all close to the CWTP. Two similar lakes 30 km upstream were chosen as controls. Water samples were taken monthly from March to November 2022. We analysed pH, electrical conductivity (EC), the content of Cl-, total nitrogen (TN), NH4+, NO3-, total phosphorus (TP), PO43-, dissolved organic carbon (DOC), Ca2+, K+, Mg2+ and Na+. Statistical analysis indicated that the canal that drains, among others, the cooling towers wastewater, might have an impact on the nearby lakes, significantly increasing their content of Cl- and Na+. On the other hand, the concentration of NH4+ was significantly higher in the lakes located downstream of the CWTP, although they did not have any surface connection with the CWTP reservoir. This fact and NH4+-polluted water seeping under the dike indicate that the CWTP reservoir might be leaking. Further research on underground water is required to establish whether the CWTP reservoir is properly secured. It is extremely important because the CWTP is located in the Vistula River valley, which supplies drinking water to almost 2 mln people. Any damage to the reservoir, e.g., during a flood, would lead to an ecological disaster involving not only the Vistula but also the Baltic Sea, affecting millions of people.

Effect of Supplementation with Curcuma longa and Rosmarinus officinalis Extract Mixture on Acute Phase Protein, Cathelicidin, Defensin and Cytolytic Protein Gene Expression in the Livers of Young Castrated Polish White Improved Bucks.

Goats are an excellent animal model for research on some physiological and pathophysiological processes in humans. The search for supplements that prevent homeostasis disorders and strengthen the immune system is necessary to reduce the risk of many diseases in both humans and animals. The aim of the study was to analyze the effect of supplementation with a mixture of dried extracts of Curcuma longa and Rosmarinus officinalis on the expression of acute-phase protein (SAA, HP, CRP, LALBA, AGP, CP, FGA, FGB, and FGG), cathelicidin (BAC5, BAC7.5, BAC3.4, MAP28, MAP34, and HEPC), beta-defensin-1 (GBD1, DEFB1), and beta-defensin-2, and cytolytic protein (LIZ and LF) genes in the livers of young castrated bucks of the Polish White Improved breed. The higher expression of LF in the control group suggests that it is important for the first line of hepatic immune defense and its expression is downregulated by the mixture of turmeric and rosemary extracts; thus, the spice-herb mixture mutes its activity. The lower expression of FGB and the higher expression of BAC5 genes in the livers of healthy, young castrated bucks who were administered the supplement suggest the silencing effects of the mixture on the acute-phase response and the stimulating effect on the antimicrobial activity of the immune system.

A multifaceted assessment of the nutritional status, diet and eating habits of midwives working on a shift schedule in Wroclaw, Poland: evaluation of macronutrients, vitamins and minerals in the diets of midwives participating in the study.

OBJECTIVES: The aim of the study was to assess the nutritional status and diet of midwives working on a shift schedule in public hospitals in Wroclaw, Poland, and to analyze the variation in their diet according to their working hours (day shift, night shift) and on a non-working day. MATERIAL AND METHODS: In the group of 50 midwives, employed in 4 public hospitals in Wroclaw weight and body composition, waist and hip circumference, waist-hip-ratio and BMI were assessed. The nutritional habits and quality of the study participants' diets were assessed by 3-days food dietary recall, including 1 day shift day, 1 night shift day, and 1 non-working day. RESULTS: More than half of the subjects were assessed as having excess body weight (BMI ≥25 kg/m2). Thirty percent of participants had BMI ≥25-<30 kg/m2 and 24% BMI ≥30 kg/m2, 70% had a body fat percentage >30%. Fifty-six percent of the diets had an energy value <90% of the subject's total daily energy expenditure. Significantly higher energy value of diets on the night shift day compared to the morning shift day (1959.05±596.09 kcal vs. 1715.36±654.55 kcal, p = 0.01) were observed. The same relationship applied to cholesterol content (349.50±155.33 mg vs. 261.39±190.59 mg, p = 0.002). A high intake of phosphorus and sodium, exceeding the recommended dietary intake, was noticed. CONCLUSIONS: The occurrence of a night shift in the shift work schedule is an element of that model that may have a significant impact on the nutritional and health value of shift workers' diets. Therefore, it seems reasonable to implement nutritional education programs promoting healthy eating choices and habits during night work. Int J Occup Med Environ Health. 2023;36(5):618-31.

Antimicrobial Properties and Assessment of the Content of Bioactive Compounds Lavandula angustifolia Mill. Cultivated in Southern Poland.

Lavender is a valued plant due to its cosmetic, perfumery, culinary, and health benefits. A wide range of applications is related to the composition of bioactive compounds, the quantity and quality of which is determined by various internal and external factors, i.e., variety, morphological part of the plant, and climatic and soil conditions during vegetation. In the presented work, the characterization of antimicrobial properties as well as the qualitative and quantitative assessment of bioactive compounds in the form of polyphenols in ethanol extracts from leaves and flowers of Lavandula angustifolia Mill. intended for border hedges, cultivated in the region of southern Poland, were determined. The composition of the fraction of volatile substances and antioxidant properties were also assessed. The conducted research shows that extracts from leaves and flowers significantly affected the viability of bacterial cells and the development of mold fungi. A clear decrease in the viability of bacteria and C. albicans cells was shown in the concentration of 0.32% of extracts. Leaf extracts were characterized by a much higher content of polyphenols and antioxidant properties than flower extracts. The composition of volatiles measured by GC-MS was significantly different between the extracts. Linalyl acetate and ocimene isomers mix dominated in flower extracts, whereas coumarin, γ-cadinene, and 7-methoxycoumarin were identified as dominant in leaf extracts.

Survey of Beliefs about Hypnosis among Students, Therapists, Followers of Paranormal Beliefs, and the General Public in Poland.

The aim of the present study is to examine beliefs about hypnosis in a Polish sample, with a focus on possible misconceptions. The research included groups with different backgrounds regarding hypnosis: 1st- and 5th-year psychology students, psychotherapists using hypnosis, people interested in paranormal phenomena, and people from the general population. The results demonstrated mild misconceptions about hypnosis and significant differences in beliefs about hypnosis between the aforementioned groups. Additionally, within a Polish sample, psychotherapists using hypnosis and 5th-year students' views were most similar in their current scientific knowledge about hypnosis, while the groups targeting individuals unexposed to hypnosis and followers of paranormal beliefs showed significantly more misconceptions.

Prenatal polyunsaturated fatty acids and atopic dermatitis and food allergy in children from Polish Mother and Child Cohort study.

OBJECTIVES: Polyunsaturated fatty acids (PUFAs) are involved both in immune system regulation and inflammation. The aim of this prospective study was to evaluate the association between maternal dietary intake of PUFAs during pregnancy and atopic dermatitis (AD) and food allergy (FA) in their children up to 7-9 years of age. MATERIAL AND METHODS: The study population consists of 557 mother-child pairs from the Polish Mother and Child Cohort (REPRO_PL). Based on the Food Frequency Questionnaire completed between the 20-24th weeks of pregnancy, n-3 and n-6 PUFAs as well as n-6:n-3 fatty acid ratio were estimated using food composition tables. Children's health examinations at the age of 1, 2, and 7-9 years were performed by an allergist. Generalized estimating equations were performed in order to assess the prevalence of AD and FA at 3 time points. Independent variables in the equation were n-3, n-6 PUFAs and n-6:n-3 PUFAs ratio. In addition multivariate models were performed to assess the association of PUFAs with AD and FA. RESULTS: The prevalence of AD was 37%, 26% and 21% and FA 26%, 22% and 22% at age of 1, 2 and 7-9 years, respectively. Higher n-6:n-3 fatty acid ratio correlated with higher prevalence of AD at age of 7-9 years (p < 0.07). In multivariate model n-6 PUFAs were significantly associated with increased risk of persistent FA (OR = 1.5, 95% CI: 1.1-2.1). CONCLUSIONS: These results may contribute to the existing knowledge on the impact of maternal diet during pregnancy on children's optimal health, however further studies are needed before drawing conclusions and creating clinical practice guidelines.
