Abstract
Fumonisin B1, T-2 toxin, and deoxynivalenol are frequently detected in feed materials. The mycotoxins induce free radical formation and, thereby, lipid peroxidation. The effects of mycotoxin exposure at the EU recommended limit (T-2/HT-2 toxin: 0.25 mg/kg; DON = 3AcDON/15-AScDON: 5 mg/kg; fumonisin B1: 20 mg/kg) and double dose (T-2/HT-2 toxin: 0.5 mg/kg, DON/3-AcDON/15-AcDON: 10 mg, and FB1: 40 mg/kg feed) were investigated during short-term (3 days) per os exposure in the liver of laying hens. On day 1 higher while on day 3 lower MDA concentrations were found in the low-dose group compared to the control. Fatty acid composition also changed: the proportion of monounsaturated fatty acids increased (p < 0.05) and the proportion of polyunsaturated fatty acids decreased by day 3. These alterations resulted in a decrease in the index of unsaturation and average fatty acid chain length. Histopathological alterations suggested that the incidence and severity of liver lesions were higher in the mycotoxin-treated laying hens, and the symptoms correlated with the fatty acid profile of total phospholipids. Overall, the findings revealed that mycotoxin exposure, even at the EU-recommended limits, induced lipid peroxidation in the liver, which led to changes in fatty acid composition, matched with tissue damage.

Abstract
Zearalenone (ZEN) is a mycoestrogen produced by Fusarium fungi. ZEN is a frequent contaminant in cereal-based products, representing significant health threat. The major reduced metabolites of ZEN are α-zearalenol (α-ZEL) and β-zearalenol (β-ZEL). Since the toxicokinetic interactions of ZEN/ZELs with cytochrome P450 enzymes (CYPs) and organic anion transporting polypeptides (OATPs) have been barely characterized, we examined these interactions applying in vitro models. ZEN and ZELs were relatively strong inhibitors of CYP3A4 and moderate inhibitors of CYP1A2 and CYP2C9. Both CYP1A2 and CYP3A4 decreased ZEN and β-ZEL concentrations in depletion assays, while only CYP1A2 reduced α-ZEL levels. OATPs tested were strongly or moderately inhibited by ZEN and ZELs; however, these mycotoxins did not show higher cytotoxicity in OATP-overexpressing cells. Our results help the deeper understanding of the toxicokinetic/pharmacokinetic interactions of ZEN, α-ZEL, and β-ZEL.

Abstract
Biological membranes, primarily composed of lipids, envelop each living cell. The intricate composition and organization of membrane lipids, including the variety of fatty acids they encompass, serve a dynamic role in sustaining cellular structural integrity and functionality. Typically, modifications in lipid composition coincide with consequential alterations in universally significant signaling pathways. Exploring the various fatty acids, which serve as the foundational building blocks of membrane lipids, provides crucial insights into the underlying mechanisms governing a myriad of cellular processes, such as membrane fluidity, protein trafficking, signal transduction, intercellular communication, and the etiology of certain metabolic disorders. Furthermore, comprehending how alterations in the lipid composition, especially concerning the fatty acid profile, either contribute to or prevent the onset of pathological conditions stands as a compelling area of research. Hence, this review aims to meticulously introduce the intricacies of membrane lipids and their constituent fatty acids in a healthy organism, thereby illuminating their remarkable diversity and profound influence on cellular function. Furthermore, this review aspires to highlight some potential therapeutic targets for various pathological conditions that may be ameliorated through dietary fatty acid supplements. The initial section of this review expounds on the eukaryotic biomembranes and their complex lipids. Subsequent sections provide insights into the synthesis, membrane incorporation, and distribution of fatty acids across various fractions of membrane lipids. The last section highlights the functional significance of membrane-associated fatty acids and their innate capacity to shape the various cellular physiological responses.

Abstract
The mechanistic target of the rapamycin signaling pathway serves as a central regulator of cell metabolism, growth, proliferation, and survival. In its regulation, the GTPase-activating protein activity toward Rags1 complex has an inhibitory effect. Mutations in genes encoding this complex protein are among the most common abnormalities in focal epilepsies. Within these mutations, the mutations affecting the DEPDC5 gene have been associated with different autosomal dominantly inherited epilepsy types. Due to the limited data available on mTOR inhibitor therapy in nontuberous sclerosis complex epileptic patients, here we present the clinical management of a patient with intractable epilepsy, skin hypopigmentation, and a DEPDC5 variant. The patient's phenotype is compatible with a nonlesional DEPDC5-related epileptic encephalopathy. We initiated compassionate, off-label everolimus treatment as the patient's condition continuously deteriorated. Due to bilateral pneumonia occurring at the beginning of the treatment, it was temporarily discontinued, and resumed in half the dose. Follow-up examination after 18 months showed a 90% reduction in seizure frequency with moderate improvement in attention function and nutritional status. Our case report emphasizes the importance of early genetic testing in patients with epileptic encephalopathy. Clinical consequences of mammalian target of rapamycin complex 1 (mTORC1) upregulation may be amenable to tailored treatment with mTOR inhibitors. A clinical trial on an international scale would be needed to draw conclusions.

Abstract
Background Hormone level changes after heart surgeries are a widely observed phenomenon due to neurohormonal feedback mechanisms that may affect postoperative morbidity and mortality. The current study aimed to analyze the changes in thyroid and sex hormones in the first 24 postoperative hours after heart surgery. Methods This prospective, observational study (registered on ClinicalTrials.gov: NCT03736499; 09/11/2018) included 49 patients who underwent elective cardiac surgical procedures at a tertiary heart center between March 2019 and December 2019. Thyroid hormones, including thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4), and sex hormones, including prolactin (PRL) and total testosterone, were measured preoperatively and at 24 h postoperatively. Results Significant decreases in serum TSH (P < 0.001), T3 (P < 0.001) and total testosterone (P < 0.001) levels were noted, whereas T4 (P = 0.554) and PRL (P = 0.616) did not significantly change. Intensive care unit (ICU) hours (P < 0.001), mechanical ventilation (P < 0.001) and Vasoactive-Inotropic Score (VIS) (P = 0.006) were associated with postoperative T3 level. ICU hours were associated with postoperative T4 level (P = 0.028). Postoperative and delta testosterone levels were in connection with lengths of stay in ICU (P = 0.032, P = 0.010 respectively). Model for End-Stage Liver Disease (MELD) scores were associated with thyroid hormone levels and serum testosterone. Conclusions T3 may represent a marker of nonthyroidal illness syndrome and testosterone may reflect hepatic dysfunction. In addition, PRL may act as a stress hormone in female patients.

Abstract
A 25-week experiment was undertaken to explore the effect of partial replacement of dietary fishmeal (FM) with black soldier fly meal (Hermetia illucens) (BS), mealworm meal (Tenebrio molitor) (MW), and a 1 : 1 mixture of both insect meals (BSMW) on fillet quality in African catfish (Clarias gariepinus). A total of 96 fish with an average initial body weight of 248 ± 28 g were stocked into a recirculating aquaculture system and fed in four different dietary groups (control, BS, MW, and BSMW). No mortality was recorded in any of the groups. At the end of the feeding period, 24 fish (n = 6 for each treatment, weight between 690 and 822 g) were used for analysis. There was no alteration in filleting yield or other slaughter indices within experimental groups, except the hepatosomatic index. Among quality attributes, pH 24 hr postmortem exhibited a significant difference (p < 0.05). In respect of the fatty acid profile, the n-6/n-3 ratio ranged between 1.17 and 1.40 but was not significantly modified by the partial replacement of FM. Similarly, the proximate composition of the fillets was not significantly different between the control and experimental diet groups. The ratio of polyunsaturated fatty acid to saturated fatty acids ranged between 0.67 and 0.79 in the fillets, without significant differences between groups. The atherogenic index was increased in the BS group, as compared to the others; however, the thrombogenicity index of fillets was not significantly affected. Similarly, the conventional quality traits of the fillet, such as cooking, drip, and thawing losses, did not differ within treatments. This study demonstrates that the dietary inclusion of black soldier fly and/or mealworm meals used for African catfish at the tested inclusion level has negligible impact on fillet properties.

Abstract
Down syndrome (DS) is a leading human genomic abnormality resulting from the trisomy of chromosome 21. The genomic base of the aneuploidy behind this disease is complex, and this complexity poses formidable challenges to understanding the underlying molecular basis. In the spectrum of the classic DS risk factor associations, the role of nutrients, vitamins, and, in general, the foodborne-associated background, as part of the events ultimately leading to chromosome nondisjunction, has long been recognized as a well-established clinical association. The integrity of the microbiome is a basic condition in these events, and the dysbiosis may be associated with secondary health outcomes. The possible association of DS development with maternal gut microbiota should therefore require more attention. We have hypothesized that different classes of antibiotics might promote or inhibit the proliferation of different microbial taxa; and hence, we might find associations between the use of the different classes of antibiotics and the prevalence of DS through the modification of the microbiome. As antibiotics are considered major disruptors of the microbiome, it could be hypothesized that the consumption/exposure of certain classes of antibiotics might be associated with the prevalence of DS in European countries (N = 30). By utilizing three different statistical methods, comparisons have been made between the average yearly antibiotic consumption (1997-2020) and the estimated prevalence of people living with DS for the year 2019 as a percentage of the population in European countries. We have found strong statistical correlations between the consumption of tetracycline (J01A) and the narrow-spectrum, beta-lactamase-resistant penicillin (J01CF) and the prevalence of DS.

Abstract
This study investigated effects of dietary fumonisins (FBs) on gut and faecal microbiota of weaned pigs. In total, 18 7-week-old male pigs were fed either 0, 15 or 30 mg FBs (FB1 + FB2 + FB3)/kg diet for 21 days. The microbiota was analysed with amplicon sequencing of the 16S rRNA gene V3-V4 regions (Illumina MiSeq). Results showed no treatment effect (p > 0.05) on growth performance, serum reduced glutathione, glutathione peroxidase and malondialdehyde. FBs increased serum aspartate transaminase, gamma glutamyl-transferase and alkaline phosphatase activities. A 30 mg/kg FBs treatment shifted microbial population in the duodenum and ileum to lower levels (compared to control (p < 0.05)) of the families Campylobacteraceae and Clostridiaceae, respectively, as well as the genera Alloprevotella, Campylobacter and Lachnospiraceae Incertae Sedis (duodenum), Turicibacter (jejunum), and Clostridium sensu stricto 1 (ileum). Faecal microbiota had higher levels of the Erysipelotrichaceae and Ruminococcaceae families and Solobacterium, Faecalibacterium, Anaerofilum, Ruminococcus, Subdoligranulum, Pseudobutyrivibrio, Coprococcus and Roseburia genera in the 30 mg/kg FBs compared to control and/or to the 15 mg/kg FBs diets. Lactobacillus was more abundant in the duodenum compared to faeces in all treatment groups (p < 0.01). Overall, the 30 mg/kg FBs diet altered the pig gut microbiota without suppressing animal growth performance.

Abstract
Purpose The frailty concept has become a fundamental part of daily clinical practice. In this study our purpose was to create a risk estimation method with a comprehensive aspect of patients' preoperative frailty. Patients and methods In our prospective, observational study, patients were enrolled between September 2014 and August 2017 in the Department of Cardiac Surgery and Department of Vascular Surgery at Semmelweis University, Budapest, Hungary. A comprehensive frailty score was built from four main domains: biological, functional-nutritional, cognitive-psychological and sociological. Each domain contained numerous indicators. In addition, the EUROSCORE for cardiac patients and the Vascular POSSUM for vascular patients were calculated and adjusted for mortality. Results Data from 228 participants were included for statistical analysis. A total of 161 patients underwent vascular surgery, and 67 underwent cardiac surgery. The preoperatively estimated mortality was not significantly different (median: 2.700, IQR (interquartile range): 2.000-4.900 vs. 3.000, IQR: 1.140-6.000, P = 0.266). The comprehensive frailty index was significantly different (0.400 (0.358-0.467) vs. 0.348 (0.303-0.460), P = 0.001). In deceased patients had elevated comprehensive frailty index (0.371 (0.316-0.445) vs. 0.423 (0.365-0.500), P < 0.001). In the multivariate Cox model an increased risk for mortality in quartiles 2, 3 and 4 compared with quartile 1 as a reference was found (AHR (95% CI): 1.974 (0.982-3.969), 2.306 (1.155-4.603), and 3.058 (1.556-6.010), respectively). Conclusion The comprehensive frailty index developed in this study could be an important predictor of long-term mortality after vascular or cardiac surgery. Accurate frailty estimation could make the traditional risk scoring systems more accurate and reliable.

Abstract
Serine protease inhibitor Kazal type 1 (SPINK1) is a trypsin-selective inhibitor protein secreted by the exocrine pancreas. Loss-of-function SPINK1 mutations predispose to chronic pancreatitis through either reduced expression, secretion, or impaired trypsin inhibition. In this study, we aimed to characterize the inhibitory activity of mouse SPINK1 against cationic (T7) and anionic (T8, T9, T20) mouse trypsin isoforms. Kinetic measurements with a peptide substrate, and digestion experiments with β-casein indicated that the catalytic activity of all mouse trypsins is comparable. Human SPINK1 and its mouse ortholog inhibited mouse trypsins with comparable efficiency (KD range 0.7-2.2 pM), with the sole exception of T7 trypsin, which was inhibited less effectively by the human inhibitor (KD 21.9 pM). Characterization of four chronic pancreatitis-associated human SPINK1 mutations in the context of the mouse inhibitor revealed that the reactive-loop mutations R42N (human K41N) and I43M (human I42M) impaired SPINK1 binding to trypsin (KD 60 nM and 47.5 pM, respectively), whereas mutations D35S (human N34S) and A56S (human P55S) had no impact on trypsin inhibition. Our results confirmed that high-affinity trypsin inhibition by SPINK1 is conserved in the mouse, and the functional consequences of human pancreatitis-associated SPINK1 mutations can be replicated in the mouse inhibitor.

Abstract
Introduction: Pancreatic cancer is a severe oncological disease with an ever-increasing incidence and a high rate of morbidity and mortality. Therapeutic options are limited and the five-year overall survival rate is 7–20%, depending on the possibility of surgical resection and the earliness of detection. Most patients with this diagnosis die due to the resistance of tumour cells and their microenvironment to the used treatment regimes.
Methods: In our study, we focused on the implementation of two in vivo models, which are the cell-line derived xenograft (CDX) and the patient-derived xenograft (PDX). These two models differ significantly from each other methodologically, technically, financially, but also in their achieved results.
Results: In a pilot study, we managed to successfully implement the CDX model with a very aggressive and resistant PaCa-44 line of pancreatic cancer in a total of 30 NU/NU strain mice. Furthermore, we created three PDX models with various subtypes of pancreatic cancer from patients operated at the University Hospital Kralovske Vinohrady, Department of General Surgery. These tumours were re-transplanted into subsequent generations of 23 individuals of NOD/SCID strain and 47 NU/NU strain mice. The established CDX and PDX models are then used to compare conventional and experimental chemotherapy regimens.
Conclusion: The next steps will be to evaluate the effects of treatment regimens by using imaging and molecular genetic methods and to optimise the entire process for further use in precise personalised medicine for patients with pancreatic cancer. The upcoming goal is to create a library of PDX models of the most common pancreatic ductal adenocarcinoma and other rare subtypes of pancreatic cancer.

Abstract
BACKGROUND German-derived ethnicities are one of the largest ethnic groups in Hungary, dating back to the formation of the Kingdom of Hungary, which took place at the beginning of the 11th century. Germans arrived in Hungary in many waves. The most significant immigration wave took place following the collapse of the Ottoman Empire in East-Central Europe which closed the 150 year long Ottoman occupation. To date, there are no comprehensive genome-wide studies investigating the genetic makeup of the Danube Swabians. Here we analyzed 47 Danube Swabian samples collected from elderly Swabian individuals living in the Dunaszekcső-Bár area, in Danube side villages of Southwest Hungary. These Swabians, according to self-declaration, did not admix with other ethnic groups for 3-6 succeeding generations. Using Illumina Infinium 720 K Beadchip genotype data, we applied allele frequency-based and haplotype-based genome-wide marker data analyses to investigate the ancestry and genetic composition of the collected Danube Swabian samples. RESULTS Haplotype-based analyses like identity by descent segment analysis show that the investigated Danube Swabians possess significant German and other West European ancestry, but their Hungarian ancestry is also prominent. Our results suggest that their main source of ancestry can be traced back to Western Europe, presumably to the region of Germany. CONCLUSION This is the first analysis of Danube Swabian population samples based on genome-wide autosomal data. Our results establish the basis for conducting further comprehensive research on Danube Swabians and on other German ethnicities of the Carpathian basin, which can help reconstruct their origin, and identify their major archaic genomic patterns.

Abstract
Currently, sweet corn is considered an important crop due to its high sugar content and low starch content. Important sugars in sweet corn include sucrose, fructose, glucose, and maltose. The purpose of the present study was to use the yield indices of the eight examined sweet corn hybrids and the correlation of the yield indices together. Concentration is important for consumers in terms of yield indices. The research site was located at the Látókép Experimental Station of the University of Debrecen. The small plot experiment had a strip plot design with four replications. The previous crop was sweet corn; the plant density was 64 thousand/ha. The obtained result indicates that Biplot AMMI based on IPCA1 showed that the DB, NO, GS, and GB hybrids had stability and high performance in terms of yield indices. At the same time, fructose and glucose had stable parameters for the hybrids involved in the study. IPCA1 AMMI biplot showed that the ME hybrid had stability and high performance in terms of iron and zinc as well. IPCA2 AMMI biplot showed that DE, GB, and GS hybrids had stability and the highest performance on yield parameters in the scope of the research. Fructose, glucose, and sucrose had stable parameters on hybrids based on IPCA2. The DB and SE hybrids had desirable performance in Lutein and Zeaxanthin based on the biplot. The DE hybrid had a maximum performance on iron and zinc parameters.

Abstract
The gradual spread of Aspergilli worldwide is adding to the global shortage of food and is affecting its safe consumption. Aspergillus-derived mycotoxins, including aflatoxins and ochratoxin A, and fumonisins (members of the fusariotoxin group) can cause pathological damage to vital organs, including the kidney or liver. Although the kidney functions as the major excretory system in mammals, monitoring and screening for mycotoxin induced nephrotoxicity is only now a developmental area in the field of livestock feed toxicology. Currently the assessment of individual exposure to mycotoxins in man and animals is usually based on the analysis of toxin and/or metabolite contamination in the blood or urine. However, this requires selective and sensitive analytical methods (e.g., HPLC-MS/MS), which are time consuming and expensive. The toxicokinetic of mycotoxin metabolites is becoming better understood. Several kidney biomarkers are used successfully in drug development, however cost-efficient, and reliable kidney biomarkers are urgently needed for monitoring farm animals for early signs of kidney disease. β2-microglobulin (β2-MG) and N-acetyl-β-D-glucosaminidase (NAG) are the dominant biomarkers employed routinely in environmental toxicology research, while kidney injury molecule 1 (KIM-1) and neutrophil gelatinase-associated lipocalin (NGAL) are also emerging as effective markers to identify mycotoxin induced nephropathy. Pigs are exposed to mycotoxins due to their cereal-based diet and are particularly susceptible to Aspergillus mycotoxins. In addition to commonly used diagnostic markers for nephrotoxicity including plasma creatinine, NAG, KIM-1 and NGAL can be used in pigs. In this review, the currently available techniques are summarized, which are used for screening mycotoxin induced nephrotoxicity in farm animals. Possible approaches are considered, which could be used to detect mycotoxin induced nephropathy.

Abstract
PURPOSE Nonerythrocytic αII-spectrin (SPTAN1) variants have been previously associated with intellectual disability and epilepsy. We conducted this study to delineate the phenotypic spectrum of SPTAN1 variants. METHODS We carried out SPTAN1 gene enrichment analysis in the rare disease component of the 100,000 Genomes Project and screened 100,000 Genomes Project, DECIPHER database, and GeneMatcher to identify individuals with SPTAN1 variants. Functional studies were performed on fibroblasts from 2 patients. RESULTS Statistically significant enrichment of rare (minor allele frequency < 1 × 10-5) probably damaging SPTAN1 variants was identified in families with hereditary ataxia (HA) or hereditary spastic paraplegia (HSP) (12/1142 cases vs 52/23,847 controls, p = 2.8 × 10-5). We identified 31 individuals carrying SPTAN1 heterozygous variants or deletions. A total of 10 patients presented with pure or complex HSP/HA. The remaining 21 patients had developmental delay and seizures. Irregular αII-spectrin aggregation was noted in fibroblasts derived from 2 patients with p.(Arg19Trp) and p.(Glu2207del) variants. CONCLUSION We found that SPTAN1 is a genetic cause of neurodevelopmental disorder, which we classified into 3 distinct subgroups. The first comprises developmental epileptic encephalopathy. The second group exhibits milder phenotypes of developmental delay with or without seizures. The final group accounts for patients with pure or complex HSP/HA.

Abstract
Az újgenerációs szekvenáláson (NGS) alapuló diagnosztika legnagyobb előnye, hogy
nagyszámú gén párhuzamos szekvenálása révén a genetikai rendellenességek
kiterjedt repertoárját képes egyetlen vizsgálattal lefedni. Az analízis
viszonylag kisebb költsége és az adatmennyiség kezelhetőbb mennyisége folytán a
célzott génpanelek használata, illetve a teljesexom-szekvenálás (WES) a
leginkább elérhető NGS-alapú módszer. Összefoglalónkban az NGS létjogosultságát
vizsgáljuk gyermekkori genetikai rendellenességek diagnosztikájában. Áttekintjük
az öröklött anyagcserezavarok, daganatos megbetegedések és egyéb gyermekkori
genetikai rendellenességek NGS-alapú diagnosztikájában fontos szerepet játszó
géneket. A kora gyermekkori rendellenességek NGS-alapú diagnosztikájának
rutinszerű használata előtt számos technikai és klinikai kérdés vár még
megválaszolásra. Jelenleg a legnagyobb kihívást a ritka genetikai variánsok
értelmezése és a mutációk patogenitásának igazolása jelenti. Orv Hetil. 2022;

Abstract
INTRODUCTION Hepatic venous flow patterns reflect pressure changes in the right ventricle and are also markers of systemic venous congestion. Fluid management is crucial in patients undergoing cardiac surgery. METHODS Our goal was to determine which factors are associated with the increased congestion of the liver as measured by Doppler ultrasound in patients undergoing cardiac surgery. This prospective, observational study included 41 patients without preexisting liver disease who underwent cardiac surgery between 1 January 2021 and 30 September 2021 at a tertiary heart center. In addition to routine echocardiographic examination, we recorded the maximal velocity and velocity time integral (VTI) of the standard four waves seen in the common hepatic vein (flow profile) using Doppler ultrasound preoperatively and at the 20-24th hour of the postoperative period. The ratios of the retrograde and anterograde hepatic venous waves were calculated, and the waveforms were compared to the baseline value and expressed as a delta ratio. Demographic data, pre- and postoperative echocardiographic parameters, intraoperative variables (procedure, cardiopulmonary bypass time), postoperative factors (fluid balance, vasoactive medication requirement, ventilation time and parameters) and perioperative laboratory parameters (liver and kidney function tests, albumin) were used in the analysis. RESULTS Of the 41 patients, 20 (48.7%) were males, and the median age of the patients was 65.9 years (IQR: 59.8-69.9 years). Retrograde VTI growth showed a correlation with positive fluid balance (0.89 (95% CI 0.785-0.995) c-index. After comparing the postoperative echocardiographic parameters of the two subgroups, right ventricular and atrial diameters were significantly greater in the "retrograde VTI growth" group. The ejection fraction and decrement in ejection fraction to preoperative parameters were significantly different between the two groups. (p = 0.001 and 0.003). Ventilation times were longer in the retrograde VTI group. The postoperative vs. baseline delta VTI ratio of the hepatic vein correlated with positive fluid balance, maximum central venous pressure, and ejection fraction. (B = -0.099, 95% CI = -0.022-0.002, p = 0.022, B = 0.011, 95% CI = 0.001-0.021, p = 0.022, B = 0.091, 95% CI = 0.052-0.213, p = 0.002, respectively.) Conclusion: The increase of the retrograde hepatic flow during the first 24 h following cardiac surgery was associated with positive fluid balance and the decrease of the right ventricular function. Measurement of venous congestion or venous abdominal insufficiency seems to be a useful tool in guiding fluid therapy and hemodynamic management.

Abstract
The oxidation of unsaturated fatty acids and the adverse transformation of pigments from meat and spices are the primary causes of chemical degradation in processed meat products. Thymol is found in a variety of plant extracts that have been proven to effectively inhibit or slow down oxidative processes. The objective of our study was to determine whether thymol treatment of the surface of sliced paprika salami could be applied to inhibit lipid oxidation and color change during refrigerated storage. During eight weeks of storage, the malondialdehyde (MDA) levels and the ratios of saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), and n6/n3 in thymol-treated salami remained unchanged (p ≥ 0.05), whereas in the controls, the MDA levels increased by approximately twelvefold and the ratio of SFAs in the lipid fraction increased (p < 0.001), while the ratio of PUFAs decreased (p < 0.001). The application of thymol prevented decrease in yellowness (b*) of the slices and reduced decreases in redness (a*) and brightness (chroma).

Abstract
Fumonisin B1 (FB1) mycotoxin was intraperitoneally (IP) administered at the No Observed Adverse Effect Level (NOAEL = 0.2 mg/kg BW/day as IP equivalent, "L") and 5-times above ("H") to male rats, in a controlled ("C"), 5-day study (n = 10/group, total n = 30). BW (bodyweight) of H rats decreased after day 4, kidney weight after 5 days. Renal histology revealed tubular epithelial desquamation, tubular dilatation, nuclear swelling, pale chromatin, cell vacuolation and casual karyopycnosis (H). Lipidomic analysis was performed with liquid chromatography - time-of-flight mass spectrometry (LC-TOF). Renal sphinganine (Sa) concentration increased 500 (L) to 1000-fold (H) and Sa-1-P to over 200 and 350-fold, respectively), with FB1 dose-dependence. Renal triacyclglycerols, diacylglycerols, ceramides and sphingomyelins were depleted, while cholesterol and cholesterol ester concentrations increased. Spearman correlation of free sphingoid bases (Sa, Sa-1-P, sphingosine (So) and So-1-P) was positive with histopathological damage severity, sphingomyelins and ceramides provided negative relationship (-0.78 and -0.8, resp.). Two-way cluster analysis and sparse partial least squares discriminant analysis (sPLS-DA) was used for experimental group classification. Fully effective group separation was achieved for ceramides, sphingomyelins and phosphatidyl-cholines, highlighting molecular species of possible diagnostic value. Lipidomic results highlight possible re-consideration of the NOAEL.

Abstract
Beauvericin (BEA), cyclopiazonic acid (CPA), and sterigmatocystin (STC) are emerging mycotoxins. They appear as contaminants in food and animal feed, leading to economic losses and health risks. Human serum albumin (HSA) forms stable complexes with certain mycotoxins, including ochratoxins, alternariol, citrinin, and zearalenone. HSA binding can influence the toxicokinetics of xenobiotics, and albumin can also be considered and applied as a relatively cheap affinity protein. Therefore, we examined the potential interactions of BEA, CPA, and STC with HSA employing fluorescence spectroscopy, ultracentrifugation, ultrafiltration, and molecular modeling. Spectroscopic and ultracentrifugation studies demonstrated the formation of low-affinity BEA–HSA (Ka ≈ 103 L/mol) and moderately strong CPA–HSA and STC–HSA complexes (Ka ≈ 104 L/mol). In ultrafiltration experiments, CPA slightly displaced each site marker (warfarin, naproxen, and camptothecin) tested, while BEA and STC did not affect significantly the albumin binding of these drugs. Modeling studies suggest that CPA occupies Sudlow’s site I, while STC binds to the Heme site (FA1) on HSA. Considering the interactions of CPA with the site markers, the CPA–HSA interaction may have toxicological importance.

Abstract
Mutation-induced protein misfolding of pancreatic secretory enzymes and consequent endoplasmic reticulum stress can cause chronic pancreatitis. A recent study revealed that cigarette smoke also increases the risk of the disease through endoplasmic reticulum stress. Here, we investigated the cumulative cellular effect of the G233E misfolding human pancreatic lipase variant and hydroquinone; a main toxic constituent of cigarette smoke, using mammalian cell lines. We found that hydroquinone reduces cell viability on a dose-dependent manner through programmed cell death, and diminishes lipase secretion without affecting its expression. Interestingly, hydroquinone decreased the viability more markedly in cells expressing the G233E lipase variant, than in cells producing wild-type lipase. The more substantial viability loss was due to increased endoplasmic reticulum stress, as demonstrated by elevated levels of X-box binding protein 1 mRNA splicing and immunoglobulin binding protein, NAD(P)H:quinone oxidoreductase 1 and C/EBP homologous protein expression. Unresolved endoplasmic reticulum stress, and especially up-regulation of the pro-apoptotic transcription factor C/EBP homologous protein were likely responsible for the increased cell death. Our observations demonstrated that the combination of hydroquinone and misfolding pancreatic lipase variant promote increased levels of endoplasmic reticulum stress and cell death, which may predispose to chronic pancreatitis.

Abstract
Genome-wide genotype data from 48 carefully selected population samples of Transylvania-living Szeklers and non-Szekler Hungarians were analyzed by comparative analysis. Our analyses involved contemporary Hungarians living in Hungary, other Europeans, and Eurasian samples counting 530 individuals altogether. The source of the Szekler samples was the commune of Korond, Transylvania. The analyzed non-Szekler Hungarian samples were collected from villages with a history dating back to the era of the Árpád Dynasty. Population structure by principal component analysis and ancestry analysis also revealed a great within-group similarity of the analyzed Szeklers and non-Szekler Transylvanian Hungarians. These groups also showed similar genetic patterns with each other. Haplotype analyses using identity-by-descent segment discovering tools showed that average pairwise identity-by-descent sharing is similar in the investigated populations, but the Korond Szekler samples had higher average sharing with the Hungarians from Hungary than non-Szekler Transylvanian Hungarians. Average sharing results showed that both groups are isolated compared to other Europeans, and pointed out that the non-Szekler Transylvanian Hungarian inhabitants of the investigated Árpád Age villages are more isolated than investigated Szeklers from Korond. This was confirmed by our autozygosity analysis as well. Identity-by-descent segment analyses and 4-population tests also confirmed that these Hungarian-speaking Transylvanian ethnic groups are strongly related to Hungarians living in Hungary.

Abstract
Összefoglaló. Kilenc magyarországi orvostársaság közös ajánlást
alakított ki a D-vitamin javasolt normáltartományával, a D-vitamin-pótlás
adagjával és az adagolás módjával kapcsolatban. Összefoglalták azokat a klinikai
állapotokat, betegségeket, amelyek kialakulása összefüggésben lehet a
D-vitamin-hiánnyal. Magyarországon a D-vitamin-hiány – főleg a tél végére –
rendkívül gyakori. A javasolt normáltartomány alsó határa 75 nmol/l, annak
ellenére, hogy a hiány klinikai jelentősége főleg 50 nmol/l alatti értékeknél
nyilvánvaló, ám mivel a D-vitamin pótlása a javasolt dózisban biztonságos,
mindenkinél érdemes csökkenteni a D-vitamin-hiánnyal kapcsolatos egészségügyi
kockázatot. A D-vitamin-pótlás célja a hiány megszüntetése. A javasolt
normáltartomány 75–125 nmol/l, az ezt meghaladó tartományban a D-vitamin
adásának nincs további egyértelmű előnye. A normáltartomány fenntartásához
felnőttekben napi 2000 NE bevitele javasolt az UV-B sugárzástól mentes
időszakban. Gyermekeknek is javasolt a D-vitamin pótlása azokban az időszakokban
és állapotokban, mint a felnőtteknek, de az adag korfüggő módon változik.
D-vitamin-pótlásra D3-vitamin adása javasolt. Felnőttekben a
D3-vitamin-pótlás napi, heti és havi gyakoriságú adagolással is
egyformán hatásos és biztonságos. Súlyos hiányban javasolt telítő adagot
alkalmazni, majd ezt követően fenntartó adagolással kell folytatni a pótlást. A
D-vitamin-hiány jól ismert csontrendszeri, immunológiai és onkológiai hatásai
mellett egyre több adat támasztja alá előnytelen nőgyógyászati és szülészeti
hatásait is. A legerősebb érv a D-vitamin-hiány megszüntetése és a szükséges
pótlás alkalmazása mellett a halálozási kockázat D-vitamin-hiányban észlelt
növekedése. A konszenzus elkészítésének folyamata megfelelt a
Delfi-irányelveknek. Orv Hetil. 2022; 163(15): 575–584.
Summary. Nine Hungarian medical societies have developed a consensus
recommendation on the preferred normal range of vitamin D, the dose of vitamin D
supplementation and the method of administration. They summarized the clinical
conditions and diseases the development of which may be associated with vitamin
D deficiency (VDD). VDD is extremely common in Hungary, especially in late
winter. The lower limit of the recommended normal range is 75 nmol/l, although
the clinical significance of deficiency is evident mainly at values below 50
nmol/l, but since vitamin D supplementation at the recommended dose is safe, it
is worthwhile for everyone to reduce the health risk associated with VDD. The
aim of vitamin D supplementation is to prevent deficiency. The recommended
normal range is 75–125 nmol/l, above which there is no clear benefit of vitamin
D supplementation. To maintain the normal range, a daily intake of 2000 IU in
adults is recommended during the UV-B radiation-free period. Vitamin D
supplementation is also recommended for children during the same periods and
conditions as for adults, but the dose varies with age. In adults, vitamin
D3 supplementation at daily, weekly and monthly intervals is
equally effective and safe. In severe deficiency, a loading dose is recommended,
followed by maintenance supplementation. In addition to the well-known skeletal,
immunological and oncological effects of VDD, more and more data support
unfavorable gynecological and obstetric effects. The process of building the
consensus has met the requirements of the latest Delphi criteria. Orv Hetil.

Abstract
Key questions: Is there a predictive value of hepatic venous flow patterns for postoperative acute kidney injury (AKI) after cardiac surgery? Key findings: In patients who underwent cardiac surgery, retrograde hepatic venous waves (A, V) and their respective ratio to anterograde waves showed a strong association with postoperative AKI, defined as the percentage change of the highest postoperative serum creatinine from the baseline preoperative concentration (%ΔCr). The velocity time integral (VTI) of the retrograde A wave and the ratio of the retrograde and anterograde waves’ VTI were independently associated with AKI after adjustment for disease severity. Take-home message: A higher ratio of retrograde/antegrade waves in hepatic venous retrograde waves, which are related to hepatic stasis, may predict AKI after cardiac surgery. Introduction: Hepatic venous flow patterns reflect pressure changes in the right ventricle and are also markers of systemic venous congestion. Pulsatility of the inferior caval vein was used to predict the risk of acute kidney injury (AKI) after cardiac surgery. Aims: Our objective was to evaluate the association between preoperative hepatic venous flow patterns and the risk of AKI in patients after cardiac surgery. Methods: This prospective, observational study included 98 patients without preexisting liver disease who underwent cardiac surgery between 1 January 2018, and 31 March 2020, at a tertiary heart center. In addition to a routine echocardiographic examination, we recorded the maximal velocity and velocity time integral (VTI) of the standard four waves in the common hepatic vein with Doppler ultrasound. Our primary outcome measure was postoperative AKI, defined as the percentage change of the highest postoperative serum creatinine from the baseline preoperative concentration (%ΔCr). The secondary outcome was AKI, defined by KDIGO (Kidney Disease Improving Global Outcomes) criteria. Results: The median age of the patients was 69.8 years (interquartile range [IQR 25−75] 13 years). Seventeen patients (17.3%) developed postoperative AKI based on the KDIGO. The VTI of the retrograde A waves in the hepatic veins showed a strong correlation (B: 0.714; p = 0.0001) with an increase in creatinine levels after cardiac surgery. The velocity time integral (VTI) of the A wave (B = 0.038, 95% CI = 0.025−0.051, p < 0.001) and the ratio of VTI of the retrograde and anterograde waves (B = 0.233, 95% CI = 0.112−0.356, p < 0.001) were independently associated with an increase in creatinine levels. Conclusions: The severity of hepatic venous regurgitation can be a sign of venous congestion and seems to be related to the development of AKI.

Abstract
Összefoglaló. A gyermekkorban kialakuló Cushing-szindróma ritka
betegség, a leggyakrabban exogén szteroidadás következményeként jelentkezik. A
daganatos betegségek közül a hypophysis kortikotropint szekretáló adenomája,
illetve a mellékvesekéreg-tumorok okoznak a leggyakrabban Cushing-szindrómát.
Jelen tanulmányunkban egy Cushing-szindrómával diagnosztizált fiú esetét
mutatjuk be. Az endokrinológiai kivizsgálás adrenokortikotropin
(ACTH)-independens hypercortisolismust támasztott alá. A hasi MRI-felvételen egy
éles határral rendelkező, 3,5 cm nagyságú terime ábrázolódott a jobb
mellékvese-régióban. A tumort parciális mellékvese-eltávolítás során
távolították el. A szövettani elemzés mellékvesekéreg-adenomát igazolt. A
gyermek klinikailag és laborértékei alapján gyógyultnak tekinthető. A
Cushing-szindrómával kezelt betegek hosszú távú nyomon követése szükséges,
melynek során szükség szerint biztosítani kell a glükokortikoidok és az egyéb
szteroidhormonok megfelelő pótlását, a kialakult szövődmények kezelését, és
adott esetben időben fel kell ismerni a Cushing-szindróma késői relapsusát is.
Orv Hetil. 2022; 163(10): 407–412.
Summary. Cushing’s syndrome (CS) in children is a rare disease, most
frequently caused by either an adrenal tumor or a corticotropin-secreting
pituitary adenoma. Its early detection and effective treatment are highly
important to avoid the short- and long-term consequences of hypercortisolism. We
report a case of a child with Cushing’s syndrome resulting from an
adrenocortical adenoma. Endocrinological data revealed adrenocorticotropin
(ACTH) independent hypercortisolism. MRI scan of the adrenal glands showed a
single, well-encapsulated tumor on the right adrenal gland with a diameter of
3.5 cm. Adrenal gland sparing surgery was performed with total excision of the
tumor. The histological analysis confirmed the diagnosis of adrenal adenoma. The
child was cured clinically and biochemically. The long-term follow-up of
patients treated for Cushing’s syndrome should include the adequate replacement
of glucocorticoids and other steroid hormones, treatment of osteoporosis and
other pathologic effects of hypercortisolism and long-term screening for the
relapse of Cushing’s syndrome. Orv Hetil. 2022; 163(10): 407–412.

Abstract
Abstract
Guignardia bidwellii, indigenous to North America, is a significant pathogen of grapes long known in Hungary, infecting only the growing green parts of the vine (leaves, petioles, shoots, and bunches). In the absence of adequate plant protection and extreme weather conditions such as a predominantly humid, warm year, black rot of grapes can be expected. The pathogen can cause high yield losses due to grape rot and reduce wine quality if the infection is severe.
The evolution of certain biogenic amine compounds were investigated under the influence of grape black rot. The results obtained showed that they were present in low concentrations from an oenological point of view. Polyphenol composition was consistent with the literature, blackening affected mainly the concentration of catechin. Black rot fungus does not produce β-glucosidase enzyme. In terms of resveratrol content, black rot has no particular effect. However, like Botrytis cinerea, it produces glycerol and, proportionally, gluconic acid in lower concentrations.
It can be concluded that black rot of grapes does not cause health problems when introduced into wine processing.

Abstract
Magnetically frustrated systems provide fertile ground for complex behaviour, including unconventional ground states with emergent symmetries, topological properties, and exotic excitations. A canonical example is the emergence of magnetic-charge-carrying quasiparticles in spin-ice compounds. Despite extensive work, a reliable experimental indicator of the density of these magnetic monopoles is yet to be found. Using measurements on single crystals of Ho2Ir2O7 combined with dipolar Monte Carlo simulations, we show that the isothermal magnetoresistance is highly sensitive to the monopole density. Moreover, we uncover an unexpected and strong coupling between the monopoles on the holmium sublattice and the antiferromagnetically ordered iridium ions. These results pave the way towards a quantitative experimental measure of monopole density and demonstrate the ability to control antiferromagnetic domain walls using a uniform external magnetic field, a key goal in the design of next-generation spintronic devices.

Abstract
Abstract
Sensory properties of foods mainly affect purchasing decisions. In case of sausages, deterioration of pigments of meat and spices cause discolouration, while lipid oxidation leads to the formation of off-odours, and these two processes are connected. Lipid oxidation promotes the conversion of pigments, while the formation of metmyoglobin accelerates lipid oxidation. The scope of the study was to investigate the relationship between the amount of malondialdehyde equivalents (MDA) and CIELAB colour coordinates in a Hungarian sausage with paprika, sliced and stored under refrigerated conditions for 10 weeks. We detected negative correlation (P < 0.001) between the MDA-level and a* and b*; and positive correlation (P < 0.001) between the MDA-level and L*. The observed correlation between MDA level and colour coordinates supports the assumption that the oxidation of lipids and pigments are interrelated in the case of sausage with paprika.

A cross-sectional study was performed among women delivering at the Department of Obstetrics and Gynecology in 2019. Altogether 301 women were included into the study, who filled the questionnaire one or two days after delivery. Data collection was based on a self-administered questionnaire, health documentation, and maternal serum and infant cord-blood vitamin D laboratory tests. Vitamin D intake was evaluated by dietary and vitamin D containing dietary supplement intake. Statistical analyses (descriptive statistics, chi square, Pearson's correlation, Kruskal-Wallis test) were performed with the IBM SPSS 26.0 program. The study protocol was approved by the Research Ethics Committee of the University of Szeged (number: 4419). Written informed consent was obtained from each participant of the study.
Results
The average maternal age of the included women was 33.28 years. More than half of women did not eat sea fish during the pregnancy, 66.3% drank daily milk, 51.5% ate daily yoghurt, and 30.2% used daily margarine as a spread. During pregnancy 77.6% of included women took some kind of vitamin D containing dietary supplement with which their average daily vitamin-D supplementation was 17.19 microgram (SD = 22.45 microgram). The average serum vitamin D level was 52.81 nmol/L in mothers and 72.96 nmol/L in newborns' cord-blood. Only 12.1% of mothers, and 43.1% of their newborns reached the optimal (75 nmol/L) level.
Conclusions
Our results showed that dietary and supplementary vitamin-D intake are insufficient among pregnant women, and consequently vitamin D serum levels are also lower than the optimal among mothers and their newborns, consequently.

Abstract
BACKGROUND/OBJECTIVE Mutation-induced misfolding of digestive enzymes has been shown to cause chronic pancreatitis. Recently, heterozygous pancreatic lipase (PNLIP) mutations leading to reduced secretion were identified. The aim of the present study was to investigate whether PNLIP mutants with a secretion defect result in endoplasmic reticulum (ER) stress in cell culture models. METHODS We introduced the coding DNA for wild-type and A174P, G233E, C254R and V454F mutant PNLIP into two mammalian cell lines and carried out functional assays to assess PNLIP expression, secretion and ER stress. RESULTS We found that wild-type PNLIP was readily secreted from the investigated cell lines. In contrast, none of the lipase mutants were detectable in the conditioned media. PNLIP variants accumulated in the cells as intracellular protein aggregates probably due to misfolding in the ER. Consistent with this notion, PNLIP mutants induced ER stress, as indicated by increased mRNA levels of spliced X-box Binding Protein 1 (XBP1) and the ER chaperone Immunoglobulin Binding Protein (BiP). CONCLUSION The results indicate that PNLIP mutations associated with a lipase secretion defect cause ER stress and thereby may increase the risk for chronic pancreatitis.

Abstract
BACKGROUND The frailty score has been developed to determine physiological functioning capacity. The aim of our research was to explore the relationship between frailty factors and mortality in cardiac surgery patients. METHODS Our research is an observational, single-center, prospective cohort study (registered on ClinicalTrials.gov: NCT02224222), and we studied 69 patients who underwent elective cardiac surgery between 2014 and 2017. Thirty days before the surgery, they completed a questionnaire that contained questions related to social support, self-reported life quality-happiness, cognitive functions, anxiety and depression. Demographic, anthropometric and medical data were widely collected. The Geriatric Nutritional Risk Index (GNRI) and the Comprehensive Geriatric Assessment (CGA)-based frailty index were calculated as a sum and the domains, respectively. Cox regression and the Kaplan-Meier tests were applied to analyze survival and relative risk. The primary outcome was mid-term mortality. RESULTS The patients' mean age was 65.43 years [standard deviation (SD): 9.81 years]. The median followup was 1,656 days of survival [interquartile range (IQR), 1,336-2,081 years], during this period 14 patients died. The median of EuroSCORE II was 1.56 (1.00-2.58) points. The median preoperative albumin level was 32.80 g/L (IQR, 29.9-35.8 g/L). Major adverse cardiovascular and cerebral events (MACCEs) occurred 7 times during follow-up. The nutrition score of the CGA was significantly associated with worse long-term survival [score; hazard ratio (HR): 5.35; 95% CI: 1.10-25.91, P=0.037]. After adjustment for EuroSCORE II and postoperative complications the noncardiovascular CGA score was associated with overall mortality [adjusted hazard ratio (AHR): 1.44, 95% CI: 1.02-2.04, P=0.036]. In the multivariable Cox regression, GNRI <91 showed an increased risk for mortality (AHR: 4.76, 95% CI: 1.52-14.92, P=0.007). CONCLUSIONS The CGA-based noncardiovascular score and nutritional status should be assessed before cardiac surgery prehabilitation and may help decrease long-term mortality.

Abstract
At exactly the individual permitted EU-tolerance dietary limits, fumonisins (FB: 5 mg/kg diet) and mixed fusariotoxins (DZ: 0.9 mg deoxynivalenol + 0.1 mg zearalenone/kg diet, and FDZ: 5 mg fumonisins + 0.9 mg deoxynivalenol + 0.1 mg zearalenone/kg diet) were administered to piglets (n = 6/group) for three weeks. Bodyweights of intoxicated piglets increased, while feed conversion ratios decreased. In FDZ, both the absolute and relative weight of the liver decreased. In the renal-cellular membrane, the most pronounced alterations were in FDZ treatment, followed by individual FB exposure. In both treatments, high proportions of C20:0 and C22:0 with low fatty acid (FA) unsaturation were found. In hepatocyte phospholipids, FDZ toxins exerted antagonistic interactions, and FB had the strongest increasing effect on FA monounsaturation. Among all investigated organs, the spleen lipids were the least responsive, in which FDZ expressed synergistic reactions on C20:0 (↑ FDZ vs. FB) and C22:0 (↓ FDZ vs. DZ). The antioxidant defense of the kidney was depleted (↓ glutathione concentration by FB-exposure). Blood plasma indicated renal injury (profound increase of urea and creatinine in FB vs. DZ and FDZ). FB strongly increased total-cholesterol and low density lipoprotein concentrations, whereas FDZ synergistically increased gamma-glutamyltransferase, alkaline-phosphatase, calcium and phosphorus levels. Summarized, individual and combined multiple fusariotoxins modified the membrane lipid profile and antioxidant defense of splanchnic organs, and serum biochemicals, without retarding growth in piglets.

Abstract
Among the diseases with X-linked inheritance and intellectual disability, duplication of the Xp11.23p11.22 region is indeed a rare phenomenon, with less than 90 cases known in the literature. Most of them have been recognized with the routine application of array techniques, as these copy number variations (CNVs) are highly variable in size, occurring in recurrent and non-recurrent forms. Its pathogenic role is not debated anymore, but the information available about the pathomechanism, especially in affected females, is still very limited. It has been observed that the phenotype in females varies from normal to severe, which does not correlate with the size of the duplication or the genes involved, and which makes it very difficult to give an individual prognosis. Among the patients studied by the authors because of intellectual disability, epilepsy, and minor anomalies, overlapping duplications affecting the Xp11.23p11.22 region were detected in three females. Based on our detailed phenotype analysis, we concluded that Xp11.23p11.22 duplication is a neurodevelopmental disorder.

Abstract
A 65-day study was undertaken to test the effects of two doses (10 and 20 mg/kg) of dietary fumonisin Bs (FB) on the rabbit male reproduction system. Body and testicular weight was not affected by the intoxication, neither the fatty acid composition of the testicular total phospholipids; the testis histological analysis failed to reveal any toxic effect. The FBs increased the testicular concentration and activity of reduced glutathione and glutathione peroxidase and decreased initial phase lipid peroxidation (conjugated dienes and trienes) in a dose dependent manner. Sperm morphology and chromatin condensation were monitored on Feulgen-stained smears. No significant differences were observed between the treatment groups and between sampling time points. The live cell ratio in the sperm (as assessed with flow cytometry) was not different among groups at any of the five sampling timepoints and was also identical within groups. Similarly, the spermatozoa membrane lipid profile was also identical in all three groups after the total intoxication period. In summary, it was demonstrated that FBs in an unrealistic and unjustified high dose still do not exert any drastic harmful effect on the leporine, male reproduction system, meanwhile slightly augmenting testicular antioxidant response.

Abstract
BACKGROUND Pericardial tamponade is a serious condition which may eventually lead to severe haemodynamic disturbances and cardiac arrest. It is most often caused by the accumulation of fluid inside the pericardium, as a result of different aetiological factors such as pericarditis, neoplastic diseases, lymphatic dysfunctions, or idiopathic pericardial disease. Pericardial tamponade can develop after cardiac surgical procedures or as a complication of myocardial infarction. Collection of blood inside the pericardial sack can be the result of pericardial or cardiac trauma. It is exceedingly rare for the injury to be caused by a migrating foreign body. Although a typical picture of pericardial tamponade has been previously described, the disorder may clinically resemble an acute myocardial infarction. CASE PRESENTATION We report the case of a 58-year-old female patient complaining of new onset thoracic pain and shortness of breath. Electrocardiographic examination results were suggestive of an acute inferior myocardial infarction. However, echocardiography revealed significant pericardial tamponade. The cause was found to be a needle which remained inside the pelvis following a previous cesarean delivery, which the patient had undergone 18 years prior. In emergency setting, the needle was removed and the pericardial tamponade was resolved. Due to the prompt and efficient management, the patient had an uneventful postoperative recovery and presented no recurrence at the follow-up examinations. CONCLUSIONS The migration of foreign bodies through tissues is exceedingly rare. If present, it may cause life-threatening complications. Since the aetiology of pericardial tamponade is vast, a thorough assessment is highly important. Therefore, echocardiography is the imaging modality of choice. We wish to highlight the possibility of migrating foreign bodies as probable cause for pericardial tamponade, as well as the importance of echocardiographic methods in the fast-track evaluation of such critical conditions.

Abstract
The heat shock protein (Hsp70) level was assessed after 14 days of oral gavage-exposure to fumonisin B1 (FB1: 150 µg/animal/day), deoxynivalenol (DON: 30 µg/animal/day) and zearalenone (ZEN: 150 µg/animal/day), alone or in combinations (in additive manner: FD = FB1 + DON, FZ = FB1 + ZEN, DZ = DON + ZEN and FDZ = FB1 + DON + ZEN) in the liver, kidneys and lung of 24 adult male Wistar rats (n = 3/group). The liver was the most responsive tissue, as compared with kidney and lung. Except of DZ-treatment, mycotoxins elevated the Hsp70 levels in livers. The highest Hsp70-levels (≈ twofold) were in the DON, FD, FZ and FDZ treatments (additive effects). In the kidney, alterations (↑ ≈ twofold) were detected in ZEN, FD, FZ and DZ treatments. The least responsive organ was the lung (↑ only in FDZ, antagonistic effect). DON and ZEA exposures have altered the reduced glutathione concentration (↓) and glutathione peroxidase activity (↓) in the blood serum. The serum malondialdehyde level increased only after exposure to FD (synergistic effect), as compared with the DZ group (antagonistic effect). When the blood clinical chemistry was assessed, significant alterations were in alanine aminotransferase (80% increase in FDZ, antagonistic effect) and total protein (↓ ZEN). Results varied according to the organ, toxin type and interactions. Furthermore, oxidative stress was not the only key player behind the Hsp70 increase, in which another mechanism is suggested.

Abstract
Intravenous administration of lipid-based nanodrugs can cause hypersensitivity, also known as infusion reactions (IRs), that can be attenuated by slow infusion in adult patients. We studied the role of infusion rate and complement (C) activation in IRs in pediatric patients treated with Abelcet, and also in anesthetized rats. IRs were observed in 6 out of 10 (60%) patients who received Abelcet infusion in 4 h or less, while no patients who received the infusion in 6 h showed C activation or IRs. The rat model indicated an inverse relationship between infusion speed and Abelcet-induced hypotension, taken as an experimental endpoint of IRs, while the rise of C3a in blood, an index of C activation, directly correlated with hypotension. The results suggest that pediatric patients are more prone to produce IRs, and that the optimal infusion time of Abelcet may be much longer than the presently recommended 2 h.

Abstract
The serine protease inhibitor Kazal type 1 (SPINK1) protects the pancreas from intrapancreatic trypsin activation that can lead to pancreatitis. Loss-of-function genetic variants of SPINK1 increase the risk for chronic pancreatitis, often by diminishing inhibitor expression or secretion. Variants that are secreted normally have been presumed to be pathogenic because of defective trypsin inhibition, but evidence has been lacking. Here, we report quantitative studies on the inhibition of human trypsins by wildtype SPINK1 and seven secreted missense variants. We found that tyrosine sulfation of human trypsins weakens binding of SPINK1 because of altered interactions with Tyr43 in the SPINK1 reactive loop. Using authentic sulfated human trypsins, we provide conclusive evidence that SPINK1 variants N34S, N37S, R65Q, and Q68R have unimpaired inhibitory activity, whereas variant P55S exhibits a small and clinically insignificant binding defect. In contrast, rare variants K41N and I42M that affect the reactive-site peptide bond of SPINK1 decrease inhibitor binding by 20,000- to 30,000-fold and three- to sevenfold, respectively. Taken together, the observations indicate that defective trypsin inhibition by SPINK1 variants is an uncommon mechanism in chronic pancreatitis. The results also strengthen the notion that a decline in inhibitor levels explains pancreatitis risk associated with the large majority of SPINK1 variants.

Abstract
Background In recent decades, previous studies have noted the importance of frailty, which is a frequently used term in perioperative risk evaluations. Psychological and socioeconomical domains were investigated as part of frailty syndrome. The aim of this study was to assess the importance of these factors in mortality after vascular surgery. Methods In our prospective, observational study (ClinicalTrials.gov Identifier: NCT02224222), we examined 164 patients who underwent elective vascular surgery between 2014 and 2017. At the outpatient anaesthesiology clinic, patients completed a questionnaire about cognitive functions, depression and anxiety, social support and self-reported quality of life were assessed using a comprehensive frailty index, in addition to medical variables. Propensity score matching was performed to analyse the difference between patients and controls in a nationwide population cohort. The primary outcome was 4 year mortality. The Kaplan-Meier method and Cox regression analysis were used for statistical analyses. Results The patients’ mean age was 67.05 years (SD: 9.49 years). Mini-Mental State Examination scores of less than 27 points were recorded for 41 patients. Overall mortality rates were 22.4 and 47.6% in the control and cognitive impairment groups, respectively (p = 0.013). In the univariate Cox regression analysis, cognitive impairment measured using age- and education-adjusted MMSE scores increased the risk of mortality (AHR: 2.842, 95% CI: 1.389-5.815, p = 0.004). Conclusion Even mild cognitive dysfunction measured preoperatively using the MMSE represents a potentially important risk factor for mortality after vascular surgery.

Abstract
Összefoglaló. A Treacher Collins-szindróma a mandibulofacialis dysostosisok csoportjába tartozó kórkép. Főbb jellegzetességei a maxillaris és mandibularis dysostosis, az antimongoloid szemrések, az alsó szemhéj colobomája, illetve a vezetéses halláscsökkenés. A szindrómával járó tünetek egyénenként és családon belül is nagyon eltérőek lehetnek; legenyhébb formái csaknem észrevehetetlenek, míg a súlyosabb esetekben az életet veszélyeztető légúti szövődmények léphetnek fel. Hátterében az esetek döntő többségében a TCOF1-gén eltérései játszanak szerepet, mely eltérések autoszomális domináns módon öröklődnek. Esetbemutatásunk célja, hogy felhívjuk a figyelmet a genetikai vizsgálat elvégzésének fontosságára olyan, klinikailag jól felismerhető tünetegyüttes, mint a Treacher Collins-szindróma esetén. Bár a betegség a klinikai kép alapján diagnosztizálható, az ismétlődés kockázatát csak úgy tudjuk pontosan meghatározni, ha ismerjük a családtagok genotípusát. A bemutatott család több tagjánál kimutatható volt a TCOF1-gén mutációja, annak ellenére, hogy klinikai tünetük nem volt. A jelenség magyarázata az inkomplett penetrancia, azaz a hibás gén fenotípusosan nem kerül kifejeződésre. Orv Hetil. 2020; 161(52): 2201-2205. Summary. Treacher Collins syndrome belongs to the group of mandibulofacial dysostoses. Its main features are maxillary and mandibular dysostosis, downward-slanting palpebral fissures, coloboma of the lower eyelid and conductive hearing loss. The symptoms associated with the syndrome can vary greatly from individual to individual and within the family. In its mildest form, the syndrome is almost imperceptible, and when severe, life-threatening respiratory complication can occur. TCOF1 is the major gene involved with an autosomal dominant mode of inheritance. The purpose of our case study is to draw attention to the importance of performing genetic testing in a clinically recognizable disorder such as Treacher Collins syndrome. Although the disease can be diagnosed based on the clinical symptoms, the risk of recurrence can only be accurately determined if the genotype of the family members is known. Several members of the presented family had a mutation in the TCOF1 gene despite having no clinical symptoms. The explanation for this phenomenon is incomplete penetrance, i.e., the defective gene is not expressed in the phenotype. Orv Hetil. 2020; 161(52): 2201-2205.

Abstract
Abstract
Background
Dietary supplements are recommended for pregnant women who cannot meet the daily dose through food intake, or who are at higher risk of deficiencies because of a substance abuse (e.g. smoking). Today, the preventive effect of folic acid (FoA) in the periconceptional period is evidence based, and there are studies about the positive effects of omega-3 fatty acids (n-3 FAs) during pregnancy. The aim of this study was to determine the association between FoA and n-3 FAs supplementation and health behavior - diet, physical activity, smoking - of pregnant women.
Methods
The cross-sectional study was conducted among women having their babies at the Department of Obstetrics and Gynecology (N = 1548). Data collection was based on self-administered questionnaire and health documentation. Uni- and multivariable logistic regression analyses were performed with IBM SPSS 26.0; the results are expressed in odds ratios (OR) and 95% confidence intervals (CI).
Results
Mean age of women was 31 years, most of them had university degree, nearly 90% of them lived in partnership. The prevalence of smoking during pregnancy was 6.5%, 39.8% did not consume fruits/vegetables daily, 58.5% ate fish less than weekly, 47.9% were physically inactive; 67.6% took FoA, and 30.6% n-3 FAs. FoA and n-3 FAs taking were more likely among those who ate fruits and vegetables every day (OR/CI: 1.30/1.01-1.66; 1.47/1.15-1.89) and among non-smokers (OR/CI: 1.73/1.06-2.83; 4.80/1.69-13.61), while FoA consumption associated with physical activity (OR/CI: 1.37/1.07-1.74) and n-3 FAs with fish consumption (OR/CI: 1.35/1.06-1.72).
Conclusions
Our results showed that a high proportion of pregnant women did not follow a healthy lifestyle, and the unhealthy behavior was significantly associated with the less frequent use of dietary supplementation. The results call the attention for the importance of counseling on healthy lifestyle and appropriate supplement use before and during pregnancy.
Key messages
Use of dietary supplementation is higher among pregnant women following a healthy way of lifestyle. The results reinforce the importance of lifestyle counseling during pregnant care.
