RESUMEN
Background: It has been reported that central adrenal insufficiency (CAI) in pediatric patients (pts) with Prader-Willi syndrome (PWS) may be a potential cause of their sudden death. In addition, the risk of CAI may increase during treatment with recombinant human growth hormone (rhGH). Objective: To prevent both over- and undertreatment with hydrocortisone, we evaluated the prevalence of CAI in a large multicenter cohort of pediatric pts with PWS analyzing adrenal response in the low-dose ACTH test (LDAT) and/or the glucagon stimulation test (GST) and reviewing the literature. Methods: A total of 46 pts with PWS were enrolled to the study, including 34 treated with rhGH with a median dose of 0.21 mg/kg/week. LDAT was performed in 46 pts, and GST was carried out in 13 pts. Both tests were conducted in 11 pts. The tests began at 8:00 a.m. Hormones were measured by radioimmunoassays. Serum cortisol response >181.2 ng/mL (500 nmol/L) in LDAT and >199.3 ng/mL (550 nmol/L) in GST was considered a normal response. Additionally, cortisol response delta (the difference between baseline and baseline) >90 ng/mL and doubling/tripling of baseline cortisol were considered indicators of normal adrenal reserve. Results: Three GSTs were not diagnostic (no hypoglycemia obtained). LDAT results suggested CAI in four pts, but in two out of four pts, and CAI was excluded in GST. GST results suggested CAI in only one patient, but it was excluded in LDAT. Therefore, CAI was diagnosed in 2/46 pts (4.3%), 1 treated and 1 untreated with rhGH, with the highest cortisol values of 162 and 175 ng/dL, but only in one test. However, in one of them, the cortisol delta response was >90 ng/mL and peak cortisol was more than tripled from baseline. Finally, CAI was diagnosed in one patient treated with rhGH (2.2%). Conclusion: We present low prevalence of CAI in pediatric pts with PWS according to the latest literature. Therefore, we do not recommend to routinely screen the function of the hypothalamic-pituitary-adrenal axis (HPAA) in all pts with PWS, both treated and untreated with rhGH. According to a review of the literature, signs and symptoms or low morning ACTH levels suggestive of CAI require urgent and appropriate diagnosis of HPAA by stimulation test. Our data indicate that the diagnosis of CAI should be confirmed by at least two tests to prevent overtreatment with hydrocortisone.

The primary aim of this study was to determine whether perceptions of criminal sanctioning and school punishment predict students' willingness to report different types of bullying (material, physical, sexual, verbal, relational, and cyberbullying). An online survey was conducted with secondary school students (n = 1092) as participants. Traditionally included predictors (trust toward school staff, cost of reporting bullying, gender, and school agency) were also incorporated into a multiple linear regression analysis. The perception of criminal sanctioning for a particular type of bullying was a significant predictor of the willingness to report a given type of bullying, whereas anticipation of school punishment was relevant only in the case of cyberbullying. Trust toward school staff and gender were also significant predictors of willingness to report any type of bullying. School agency helped predict the willingness to report any kind of bullying except cyberbullying. Surprisingly, the costs of reporting bullying were relevant only in the case of material bullying. These results have important implications for stakeholders and school administration in identifying unreported bullying, developing and implementing anti-bullying policies, and introducing programs aimed at improving students' legal awareness.
RESUMEN
Severe obesity defined as BMI value corresponding to an adult > 40 kg/m2 affects 1-5% of children and adolescents in Europe. The purpose of this study was to assess the occurrence of cardiovascular risk factors in children and adolescents with severe obesity. The analysis included 140 patients (75 female) at the mean age of 14 ± 2.1 SD (range 10-18) years (all recruited in 4 regional reference centers in Poland). Severe obesity was defined as BMI > 35 kg/m2 (children 6-14 years), and BMI > 40 kg/m2 (> 14 years). Fasting plasma samples have been obtained in all patients, and OGTT was performed in all patients. The metabolic risk factors were defined as high blood pressure (BP > 90 percentile for height, age, and sex), HDL cholesterol < 1.03 mmol/L, TG ≥ 1.7 mmol/L, and hyperglycemic state (fasting blood glucose > 5.6 mmol/L, or blood glucose 120' after oral glucose load > 7.8 mmol/L). Additionally, the MetS z-score was calculated using Metabolic Syndrome Severity Calculator. One hundred twenty-four (89%) participants presented with high BP, 117 (84%) with abnormal lipid profile, and 26 with the hyperglycemic. Only 12 (9%) were free of metabolic complications. More than 60% of patients had more than one cardiovascular risk factor. The high BP was significantly associated with the severity of obesity (F = 9.9, p = 0.002). Patients with at least one metabolic complication presented with significantly younger age of the onset of obesity (the mean age of the patients with no overt obesity complications was 10 years, while the mean age of those who presented at least one was 4.7 ± 3.5 SD years (p = 0.002)). A significant positive association between in the value of the Mets BMI z-score with age was observed (R = 0.2, p < 0.05). There were no differences between girls and boys regarding Mets BMI z-score (1.7 ± 0.8 vs 1.7 ± 0.7, p = 0.8).Conclusions: The most common metabolic risk factor in children and adolescents with severe obesity was high BP. The most important factor determining presence of obesity complications, and thus the total metabolic risk, seems to be younger (< 5 years) age of onset of obesity. What is Known? ⢠It is estimated that 1-5% of children and adolescents in Europe suffer from severe obesity corresponding to an adult BMI > 40 kg/m2, and it is the fastest growing subcategory of childhood obesity. ⢠Children with severe obesity face substantial health risk that may persist into adulthood, encompassing chronic conditions, psychological disorders and premature mortality. What is new: ⢠The most common complication is high BP that is significantly associated with the severity of obesity (BMI z-score), contrary to dyslipidemia and hyperglycemic state, which do not depend on BMI z-score value. ⢠The most important factor determining presence of obesity complications, and thus the total metabolic risk, seems to be younger (< 5 years) age of onset of obesity.

Introduction: Body mass composition is directly related to health and its disorders are correlated with diseases such as obesity, diabetes, osteoporosis and sarcopenia. The purpose of this study was to analyze body mass composition among traditional elementary school students and ballet school students. Methods: A total of 340 students participated in the study, 95 of whom attended ballet school and 245 elementary school students. A Tanita BC-418 MA analyzer was used to analyze body mass composition. Such body composition indices as BMI (Body Mass Index), muscle mass, fat mass, lean body mass and water content were evaluated. Results: The results show statistical significance for BMI between high school ballet students and elementary school ballet students, as well between high school ballet students and elementary school students. Comparisons in relation to gender and schools BMI, statistical significance was obtained for: BHSw (ballet high school women) and EBSw (elementary ballet school women), BHSw and ESw (elementary school women), BHSm (ballet high school men) and EBSm (elementary ballet school men), and between BHSm and ESw. Comparing muscle mass index (kg) between ballet high school and elementary school, between ballet high school and elementary school, and between ballet high school and elementary school - statistical significance was obtained for all comparisons. Analyzing in pairwise comparisons by gender and school achieved a statistically significant difference for: BHSw and EBSw, BHSm and EBSw, EBSw and ESm. Comparing the fat mass index (kg), no significant differences were observed between the analyzed schools and the school and gender of the children studied. The value of the lean body mass index differed significantly between groups by school and gender. Comparing the water content index, statistically significant differences were obtained for school and gender. Discussion: The body mass composition of ballet school students differs from that of standard school students.

Pregnancy affects a woman's physiological and psychological state. One of the most important aspects that requires attention is the quality of life of pregnant women. The quality of life of women during this period is influenced by a number of factors, such as back and pelvic pain, physiotherapy and physical activity, and also sexual satisfaction. Eighty-five women aged 21-40 years (30.80 ± 5.05) in pregnancy trimesters participated in the study: 17 women were in the first trimester, 32 women were in the second, and 36 women in the third trimester. The World Health Organisation Quality of Life (WHOQOL-BREF), Oswestry Disability Index (ODI) and the Sexual Satisfaction Scale for Women SSS-W-R15 were used to answer the research hypotheses. Respondents also provided information on questions regarding physiotherapy treatments and physical activity. Quality of life (WHOQOL-BREF) and disability due to back pain (ODI) showed a statistical association and relationship (p-value = 0.045, rho = - 0.22). Quality of life (WHOQOL-BREF) has an association with sexual satisfaction in pregnant women (SSS-W-R15) (p-value = 0.003, rho = 0.32). The trimester of pregnancy has an effect on ODI (p-value = 0.027). A significant effect occurred in a detailed comparison between the first and third trimesters of pregnancy (p-value = 0.026). The trimester also has an impact on quality of life (WHOQOL-BREF) (p-value = 0.002). In a detailed analysis, a significant effect occurred between the first and third trimesters of pregnancy (p-value = 0.001). Moreover, the trimester of pregnancy has an impact on sexual satisfaction (SSS-W-R15) (p-value = 0.027). After detailed statistical analysis, a significant effect occurred between trimesters one and three of pregnancy (p-value = 0.046). On the other hand, the number of days of physical activity performed by pregnant women per month and the type of physical activity had no effect on the ODI (p-value = 0.071). The type of physical activity performed by pregnant women also has no effect on ODI (p-value = 0.023). The number of physiotherapy treatments used has no effect on the ODI (p-value = 0.156). Type of physiotherapy treatment has no effect on ODI (p-value = 0.620). Normal pregnancy quality of life (WHOQOL) is related to ODI and sexual satisfaction (SSS-W-R15), while the trimester of pregnancy also has an impact on quality of life, disability due to back pain and sexual satisfaction.

INTRODUCTION: Lymphocytic hypophysitis (LH) is a rare inflammatory disorder of the pituitary or/and hypothalamus with variable disease course: from spontaneous remission to pituitary atrophy. The diagnosis, treatment and follow-up remain challenging. The aim of the study is to present long-term data and an individualized therapeutic approach and propose an algorithm for the follow-up of patients with probable LH. MATERIAL AND METHODS: A retrospective analysis of 18 consecutive adult patients (13 W/5 M, mean age 45.2 years) with LH diagnosed and treated in a tertiary referral center. RESULTS: The first manifestations were headaches (50.0%), polyuria/polydipsia (33.3%) and symptoms of hypopituitarism (16.7%). Somatotropic, adrenal, gonadal and thyroid axis insufficiencies were found in 44.4%, 33.3%, 33.3%, and 27.8% of patients, respectively. Arginine vasopressin deficiency was diagnosed in 8 patients (44.4%). Some of the dysfunctions were transient. Magnetic resonance imaging (MRI) revealed thickened pituitary stalk in all but 2 cases. In 2 patients an anterior pituitary lesion, most likely inflammatory was described. Four patients were given steroids (severe headaches) with clinical recovery and stable/improved MRI. One woman was operated on due to the progressive mass-related symptoms - histopathological examination confirmed LH. In the remaining 13/18 patients watchful waiting approach allowed to obtain hormonal and radiological stabilization/improvement. CONCLUSIONS: LH is a disease with a complex clinical picture and challenging diagnosis. Treatment requires an individual approach: vigilant observation is the cornerstone of therapy, with steroid/surgical treatment reserved for cases with mass-related symptoms. Further multicenter research might help in better understanding of the LH and creating standards of care in this rare disease.

BACKGROUND: Atrophic autoimmune thyroiditis (AAT) is a rare phenotype of autoimmune thyroiditis (AT) in pediatric age. AAT occurs without thyroid enlargement leading to a delay in its diagnosis. Growth impairment is infrequent in autoimmune thyroiditis, if timely diagnosed. Prolonged severe hypothyroidism is a rare cause of pituitary hyperplasia (PH) in childhood. Loss of thyroxine negative feedback causes a TRH-dependent hyperplasia of pituitary thyrotroph cells resulting in adenohypophysis enlargement. A transdifferentiation of pituitary somatotroph cells into thyrotroph cells could explain growth failure in those patients. METHODS: Twelve patients were retrospectively evaluated at five Italian and Polish Centres of Pediatric Endocrinology for height growth impairment. In all Centres, patients underwent routine clinical, biochemical and radiological evaluations. RESULTS: At the time of first assessment, the 75% of patients presented height growth arrest, while the remaining ones showed growth impairment. The study of thyroid function documented a condition of hypothyroidism, due to AT, in the entire cohort, although all patients had no thyroid enlargement. Thyroid ultrasound showed frankly atrophic or normal gland without goiter. Cerebral MRI documented symmetrical enlargement of the adenohypophysis in all patients and a homogeneous enhancement of the gland after the administration of Gadolinium-DPTA. Replacement therapy with levothyroxine was started and patients underwent close follow-up every 3 months. During the 12 months of follow-up, an improvement in terms of height growth has been observed in 88% of patients who continued the follow-up. Laboratory findings showed normalization of thyroid function and the control brain MRI documented complete regression of PH to a volume within the normal range for age and sex. CONCLUSIONS: This is the largest pediatric cohort with severe autoimmune primary hypothyroidism without goiter, but with pituitary hyperplasia in which significant growth impairment was the most evident presenting sign. AAT phenotype might be correlated with this specific clinical presentation. In youths with growth impairment, hypothyroidism should always be excluded even in the absence of clear clinical signs of dysthyroidism.

Objective: Disorders of glucose metabolism in children with obesity are less common than in adults. There is also evidence that they may be transient. The aim of this study was to determine the prevalence of impaired fasting glucose (IFG), impaired glucose tolerance (IGT), type 2 diabetes mellitus (DM2) and its reversibility in pediatric patients with obesity and to define the factors determining the reversibility of prediabetes or progression to diabetes. Methods: Retrospective analysis included 573 patients with obesity (mean BMI Z-score 4.4, 316 girls at mean age 13.5 years old, range 2.9-17.11, all Caucasians). Results: The normal results of OGTT were present in 90.8 % (n=520) and prediabetes in 9.2% (n=53) (IFG 17%, IGT 88.7%, DM 0%) subjects. Among those who underwent OGTT twice, impaired glucose regulation was present in 9.3% subjects (n=5) (IFG 40%, IGT 80%, DM 0%) at baseline and in 14.8% subject (n=8) (IFG 25%, IGT 50%, DM 25%) at follow-up after lifestyle modification only. After 12-36 months of follow up, in the previous presence of IGT, 60% reverted to NGT, 20% persisted as IFG and 20% as IGT and no one progressed to DM. The risk factors for progression of glucose metabolism disorders were increase of BMI Z-score, and higher insulin levels, and HOMA-IR. Conclusions: IFG and IGT are common in pediatric patients with obesity, while the progression to DM2 is a rare condition. Disorders of glucose metabolism disorders have reversible character. Every change of BMI Z-score has a significant impact on changes of glucose levels.
RESUMEN
The most commonly identified genetic cause of combined pituitary hormone deficiency (CPHD) is PROP1 gene mutations. The aim of the study was to compare selected clinical features of patients with CPHD caused by variants of the PROP1 gene (CPHD-PROP1) and patients with inborn CPHD of other etiology (CPHD-nonPROP1). MATERIAL AND METHODS: The retrospective analysis included childhood medical records of 74 patients (32 female) with CPHD, including 43 patients (23 female) with the mutation in the PROP1 gene. RESULTS: Patients with CPHD-PROP1 compared to the CPHD-nonPROP1 presented with the following: significantly higher median birth weight (0.21 vs. - 0.29 SDS, p = 0.019), lower growth velocity within 3 years preceding growth hormone administration (- 2.7 vs. - 0.8 SDS, p < 0.001), higher mean maximal blood concentration of growth hormone within the stimulation process (1.2 vs. 1.08 ng/mL, p = 0.003), lower TSH (1.8 vs. 2.4 µIU/mL, p < 0.001), significantly lower prolactin concentrations (128 vs. 416.3 µIU/mL, p < 0.001), and less frequent typical signs of hypogonadism at birth in boys (n = 6; 30% vs. n = 12, 54%, p < 0.001). Secondary adrenal insufficiency was less frequent in CPHD-PROP1 (20 vs. 25 cases, p = 0.006) and occurred at a later age (13.4 vs. 10.4 years). MRI of the pituitary gland in CPHD-PROP1 revealed a small pituitary gland (21 cases), pituitary gland enlargement (eight cases), and one pituitary stalk interruption and posterior lobe ectopy, while it was normal in nine cases. CONCLUSION: Patients with the PROP1 mutations present a clinical picture significantly different from that of other forms of congenital hypopituitarism. Certain specific clinical results may lead to the successful identification of children requiring diagnostics for the PROP1 gene mutation.

Childhood obesity has become a worldwide epidemic in the 21st century. Its treatment is challenging and often ineffective, among others due to complex, often not obvious causes. Awareness of the existence and meaning of psychosocial and environmental risk factors seems to be an essential element in the prevention and treatment of obesity and its complications, especially arterial hypertension. In this review, we will discuss the role of that risk factors linking obesity and increased cardiovascular disorders including the role of nutritional factors (including the role of unhealthy diet, inadequate hydration), unhealthy behaviors (e.g. smoking, alcohol and drugs, sedentary behavior, low physical activity, disrupted circadian rhythms, sleep disorders, screen exposure), unfavorable social factors (such as dysfunctional family, bullying, chronic stress, mood disorders, depression, urbanization, noise, and environmental pollution), and finally differences in cardiovascular risk in girls and boys.
RESUMEN
Obesity is currently one of the most significant public health challenges worldwide due to the continuous increase in obesity rates among children, especially younger children. Complications related to obesity, including serious ones, are increasingly being diagnosed in younger children. A search was performed from January 2023 to September 2023 using the PubMed, Cochrane Library, Science Direct, MEDLINE, and EBSCO databases. The focus was on English-language meta-analyses, systematic reviews, randomized clinical trials, and observational studies worldwide. Four main topics were defined as follows: disorders of glucose metabolism; liver disease associated with childhood obesity; the relationship between respiratory disorders and obesity in children; and the effects of obesity on the hypothalamic-pituitary-gonadal axis and puberty. Understanding potential complications and their underlying mechanisms can expedite the diagnostic process and enhance the effectiveness of treatment. We aspire that this study will bring insight into the often-overlooked complications associated with obesity.
RESUMEN
(1) Background: Fire department cadets preparing to become firefighters and paramedics experience high levels of stress when participating in incidents like traffic accidents and fires. Stress adversely affects health, and coping with it proves difficult. Unfortunately, there is no single method that reduces stress completely in humans. One non-invasive method for lowering stress hormone levels is craniosacral therapy. (2) Methods: Fifty-seven firefighting cadets aged 18-24 years (21.63 ± 1.41) participated in the study. They were randomly assigned to either a test group or a control group. Participants' blood levels of cortisol and CRH (corticotropin-releasing hormone) were assessed before and after the study. The study group underwent 5-week craniosacral therapy (1× per week). (3) Results: The Kruskal-Wallis test showed that the therapy group's results were statistically significant for CRH values (p-value = 0.00067) and for cortisol values (p-value ≤ 0.0001). Wilxocon and Dunn tests showed statistical significance for cortisol after CS therapy between the control and study groups (p = 0.0377), and for CRH between the control and study groups before (p = 0.00634) and after the study (p = 0.000887), and in the study group before and after the study (p = 0.0101). (4) Conclusions: The application of craniosacral therapy reduced stress hormone levels in male firefighter cadets. The results indicate that craniosacral therapy (five sessions, one per week) has an effect on the reduction of stress hormones.
RESUMEN
Background: It is accepted that plasma branched-chain amino acids (BCAAs) and aromatic amino acids (AAAs) are closely related to metabolic risk. Arterial hypertension, metabolic syndrome, endothelial dysfunction, inflammation, and metabolic dysfunction-associated fatty liver disease (MAFLD) are frequently seen in obese patients. Many attempts have been made to find biochemical indicators for the early detection of metabolic complications in children. It is not known if different amino acid profiles and BCAA and AA concentrations in overweight and obese children correlate with chemerin, proinflammatory, and simple biochemical markers. Thus, the study aimed to find out the early markers of cardiovascular disease and MAFLD in overweight and obese children. Materials and methods: The study included 20 overweight and obese children (M/F 12/8; mean age 7.7 ± 2.3 years; BMI 26.8 ± 5.0 kg/m2) and 12 non-obese children (control group) (M/F 4/8; mean age 6.5 ± 2.2 years; BMI 14.8 ± 1.5 kg/m2). The following plasma amino acids were measured: aspartic acid, glutamic acid, serine, asparagine, glycine, glutamine, taurine, histidine, citrulline, threonine, alanine, arginine, proline, tyrosine, methionine, valine, isoleucine, leucine, phenylalanine, tryptophan, ornithine, and lysine. Chemerin, high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), and basic biochemistry parameters were measured. Results: The mean plasma levels of leucine, isoleucine, valine, phenylalanine, tyrosine, glutamic acid, and alanine were significantly higher in overweight and obese children than in the control group (p<0.03-p<0.0004). Conversely, the mean values of serine, asparagine, glutamine, and citrulline were significantly lower in overweight and obese children than in the control group (p<0.03-p<0.0007). Isoleucine, leucine, valine (BCAAs) tyrosine, and phenylalanine (AAAs) levels showed a positive correlation with uric acid, ALT, hs-CRP, and chemerin (r=0.80-0.36; p<0.05-p<0.00001), but not with IL-6. The mean values of glucose, IL-6, hs-CRP, chemerin, uric acid, and ALT were significantly higher in overweight and obese children than in the control group (p<0.03-p<0.00002). In contrast, the lipid profile did not differ between groups. Conclusion: An abnormal amino acid profile in overweight and obese pre-pubertal children, accompanied by elevated ALT and UA observed in the studied cohort, may suggest early metabolic disturbances that can potentially lead to metabolic syndrome, or MAFLD, and increased cardiovascular risk.

Noccaea caerulescens, a hyperaccumulator plant species known for its metal tolerance and accumulation abilities, harbours a microbiome of interest within its seed. These seed-associated bacteria, often referred to as seed endophytes, play a unique role in seed germination and plant growth and health. This work aimed to address how inoculating seeds of eight different plant species-Medicago sativa (alfalfa), Zea mays (corn), Raphanus sativus (radish), Helianthus annus (sunflower), Cucurbita pepo subsp. pepo (squash), Beta vulgaris subsp. cicla (rainbow chard), Arabidopsis thaliana (thale cress), and Noccaea caerulescens (penny cress)-with a bacterial consortium made from the seed endophytes of N. caerulescens would affect the seed microbiome of each test plant species, as well as inoculation with a strain of the bacterium Sphingomonas wittichii, which was previously isolated from seeds of N. caerulescens. Additionally, we aimed to offer preliminary plant tests in order to determine the best seed treatment plan for future research. The results showed that inoculation with the bacterial consortium held the most potential for increasing plant size (p < 0.001) and increasing germination rate (p < 0.05). The plant that responded best to inoculation was N. caerulescens (penny cress), likely because the microbes being introduced into the seed were not foreign. This paper also offers the first insight into the seed endophytes of Beta vulgaris subsp. cicla, highlighting an abundance of Proteobacteria, Firmicutes, and Actinobacteriota.
RESUMEN
INTRODUCTION: It is proven that life style modification (diet and physical exercises) have positive effect on the metabolic functions in pa-tients with obesity, even without significant weight reduction. AIM OF THE STUDY: The objective of the present study was to check whether the intensive controlled lifestyle intervention (personalized diet modification and monitored, regular physical activity) may have positive impact on the concentration of irisin and chemerin in children with obesity. MATERIAL AND METHODS: Twenty children (mean age 8.9) were included in the prospective, cross-over study. They were randomly assigned to group A (with three months intensive intervention), and B (standard intervention). After three months, the groups were switched. RESULTS: Mean irisin level increased significantly after the phase of intensive intervention (4.8 to 5.1 µg/ml; p = 0.03), regardless of whether the intervention was applied from the beginning (Group A) or after 3 months from the advice of healthy-lifestyle (Group B). A period without intensive monitoring was associated with a significant reduction of irisin level. For chemerin in the group A (starting from intensive intervention) mean level decreased after the phase of intensive intervention (65.8 to 57.0 ng/ml), and then increased to 67 ng/ml during the standard intervention. In the group B after the standard intervention period chemerin level increased 67.5 to 68.8 ng/ml (p = 0.03), and then after introduction the intensive intervention de-creased to 63.7 ng/ml. CONCLUSIONS: Personalized diet modification and regular, daily exercises may positively influence on the levels of irisin and chemerin.

To identify metal adapted bacteria equipped with traits positively influencing the growth of two hyperaccumulator plant species Arabidopsis arenosa and Arabidopsis halleri, we isolated bacteria inhabiting rhizosphere and vegetative tissues (roots, basal and stem leaves) of plants growing on two old Zn-Pb-Cd waste heaps in Boleslaw and Bukowno (S. Poland), and characterized their potential plant growth promoting (PGP) traits as well as determined metal concentrations in rhizosphere and plant tissues. To determine taxonomic position of 144 bacterial isolates, 16S rDNA Sanger sequencing was used. A metabolic characterization of isolated strains was performed in vitro using PGP tests. A. arenosa and A. halleri accumulate high amounts of Zn in their tissues, especially in stem leaves. Among in total 22 identified bacterial taxa, the highest level of the taxonomical diversity (H' = 2.01) was revealed in A. halleri basal leaf endophytes originating from Bukowno waste heap area. The 96, 98, 99, and 98% of investigated strains showed tolerant to Cd, Zn, Pb and Cu, respectively. Generally, higher percentages of bacteria could synthesize auxins, siderophores, and acetoin as well as could solubilize phosphate. Nine of waste heap origin bacterial strains were tolerant to toxic metals, showed in vitro PGP traits and are potential candidates for bioremediation.

There is an immediate need to optimize cardiovascular (CV) risk management and primary prevention of childhood obesity to timely and more effectively combat the health hazard and socioeconomic burden of CV disease from childhood development to adulthood manifestation. Optimizing screening programs and risk management strategies for obesity-related CV risk in childhood has high potential to change disease trajectories into adulthood. Building on a holistic view on the aetiology of childhood obesity, this document reviews current concepts in primary prevention and risk management strategies by lifestyle interventions. As an additional objective, this scientific statement addresses the high potential for reversibility of CV risk in childhood and comments on the use of modern surrogate markers beyond monitoring weight and body composition. This scientific statement also highlights the clinical importance of quantifying CV risk trajectories and discusses the remaining research gaps and challenges to better promote childhood health in a population-based approach. Finally, this document provides an overview on the lessons to be learned from the presented evidence and identifies key barriers to be targeted by researchers, clinicians, and policymakers to put into practice more effective primary prevention strategies for childhood obesity early in life to combat the burden of CV disease later in life.

The aim of this study was to investigate the association between PMS (premenstrual syndrome)-related pain among young women following a particular type of diet during the COVID-19 pandemic. This was compared to the period before the pandemic. Furthermore, we aimed to determine whether the increase in the intensification of pain was correlated to their age, body weight, height and BMI, and whether there are differences in PMS-related pain between women who differ in their diet. A total of 181 young female Caucasian patients who met the criteria for PMS were involved in the study. Patients were divided according to the kind of diet they had followed during the last 12 months before the first medical evaluation. The rise in pain score was evaluated according to the Visual Analog Scale before and during the pandemic. Women following a non-vegetarian ("basic") diet had a significantly higher body weight in comparison to those on a vegetarian diet. Furthermore, a significant difference was noted between the level of intensification of pain before and during the pandemic in women applying a basic diet, a vegetarian and an elimination diet. Before the pandemic, women from all groups felt weaker pain than during the pandemic. No significant difference in the intensification of pain during the pandemic was shown between women with various diets, nor was there a correlation between intensification of pain and the girl's age, BMI, their body weight and also height for any of the diets applied.
