NAFLD is considered a hepatic manifestation of the metabolic syndrome due to its close associations with abdominal obesity, insulin resistance, and atherogenic dyslipidemia. Experts have proposed an alternative terminology, metabolic dysfunction-associated fatty liver disease (MAFLD), to better reflect its pathophysiology. This study aimed to develop consensus statements and recommendations for pediatric MAFLD through collaboration among international experts.A group of 65 experts from 35 countries and six continents, including pediatricians, hepatologists, and endocrinologists, participated in a consensus development process. The process encompassed various aspects of pediatric MAFLD, including epidemiology, mechanisms, screening, and management.In round 1, we received 65 surveys from 35 countries and analyzed these results, which informed us that 73.3% of respondents agreed with 20 draft statements while 23.8% agreed somewhat. The mean percentage of agreement or somewhat agreement increased to 80.85% and 15.75%, respectively, in round 2. The final statements covered a wide range of topics related to epidemiology, pathophysiology, and strategies for screening and managing pediatric MAFLD.The consensus statements and recommendations developed by an international expert panel serve to optimize clinical outcomes and improve the quality of life for children and adolescents with MAFLD. These findings emphasize the need for standardized approaches in diagnosing and treating pediatric MAFLD.This work was funded by the National Natural Science Foundation of China (82070588, 82370577), the National Key R&D Program of China (2023YFA1800801), National High Level Hospital Clinical Research Funding (2022-PUMCH-C-014), the Wuxi Taihu Talent Plan (DJTD202106), and the Medical Key Discipline Program of Wuxi Health Commission (ZDXK2021007).}, keywords = {CHILDREN; Consensus; Adolescents; Non-Alcoholic Fatty Liver Disease; MAFLD; Metabolic dysfunction-associated fatty liver disease; Translation to population health; MASLD}, year = {2024}, orcid-numbers = {Hegyi, Péter/0000-0003-0399-7259} } @article{MTMT:34836454, title = {Short-term hyperoxia-induced functional and morphological changes in rat hippocampus}, url = {https://m2.mtmt.hu/api/publication/34836454}, author = {Hencz, Alexandra Júlia and Magony, Andor Dániel and Thomas, Chloe and Kovacs, Krisztina and Szilágyi, Tamás Gábor and Pál, József and Sík, Attila}, doi = {10.3389/fncel.2024.1376577}, journal-iso = {FRONT CELL NEUROSCI}, journal = {FRONTIERS IN CELLULAR NEUROSCIENCE}, volume = {18}, unique-id = {34836454}, issn = {1662-5102}, abstract = {Excess oxygen (O2) levels may have a stimulating effect, but in the long term, and at high concentrations of O2, it is harmful to the nervous system. The hippocampus is very sensitive to pathophysiological changes and altered O2 concentrations can interfere with hippocampus-dependent learning and memory functions. In this study, we investigated the hyperoxia-induced changes in the rat hippocampus to evaluate the short-term effect of mild and severe hyperoxia. Wistar male rats were randomly divided into control (21% O2), mild hyperoxia (30% O2), and severe hyperoxia groups (100% O2). The O2 exposure lasted for 60 min. Multi-channel silicon probes were used to study network oscillations and firing properties of hippocampal putative inhibitory and excitatory neurons. Neural damage was assessed using the Gallyas silver impregnation method. Mild hyperoxia (30% O2) led to the formation of moderate numbers of silver-impregnated "dark" neurons in the hippocampus. On the other hand, exposure to 100% O2 was associated with a significant increase in the number of "dark" neurons located mostly in the hilus. The peak frequency of the delta oscillation decreased significantly in both mild and severe hyperoxia in urethane anesthetized rats. Compared to normoxia, the firing activity of pyramidal neurons under hyperoxia increased while it was more heterogeneous in putative interneurons in the cornu ammonis area 1 (CA1) and area 3 (CA3). These results indicate that short-term hyperoxia can change the firing properties of hippocampal neurons and network oscillations and damage neurons. Therefore, the use of elevated O2 concentration inhalation in hospitals (i.e., COVID treatment and surgery) and in various non-medical scenarios (i.e., airplane emergency O2 masks, fire-fighters, and high altitude trekkers) must be used with extreme caution.}, keywords = {hippocampus; Electrophysiology; HYPEROXIA; network oscillation; Dark neuron}, year = {2024}, eissn = {1662-5102} } @article{MTMT:34836452, title = {Comparative analysis of the quality of life regarding patients who underwent hip replacement in public versus private hospitals in Hungary}, url = {https://m2.mtmt.hu/api/publication/34836452}, author = {Kajos, Luca Fanni and Molics, Bálint and Than, Péter and Gőbel, Gyula and Elmer, Diána and Pónusz-Kovács, Dalma and Csákvári, Tímea and Kovács, Bettina and Horváth, Lilla and Bódis, József and Boncz, Imre}, doi = {10.1038/s41598-024-60720-4}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {14}, unique-id = {34836452}, issn = {2045-2322}, abstract = {The study aimed to investigate the impact of hip replacement surgery on the quality of life and to compare the outcomes by sociodemographic and surgical data in Hungarian public and private hospitals.

After determining the physicochemical parameters of honey, broth microdilution was applied to determine the minimum inhibitory concentration of each honey type against each bacterium, and crystal violet assay was used to test their antibiofilm effect. The possible mechanism of action was explored with membrane degradation test, while structural changes were illustrated with scanning electron microscopy. Honeys stored for one or two years were darker than fresh honeys, while older honeys had significantly lower antibacterial activity. The most remarkable inhibitory effect was exerted by linden and sunflower honeys, and P. aeruginosa proved to be the most resistant bacterium.

N‐glycosylation has a key role in functionality, stability, and half‐life of most proteins. Therefore, congenital defects of glycosylation typically are multisystem disorders. Here we report a 3‐year‐old patient with severe neurological, cardiovascular, respiratory, musculoskeletal and gastrointestinal symptoms. ALG1‐CDG was suggested based on exome sequencing and Western blot analysis. Despite her severe clinical manifestations and genetic diagnosis, serum transferrin glycoform analysis was normal. Western blot analysis of highly glycosylated proteins in fibroblasts revealed decreased intercellular adhesion molecule 1 (ICAM1), but normal lysosomal associated membrane protein 1 and 2 (LAMP1 and LAMP2) expression levels. Glycoproteomics in fibroblasts showed the presence of the abnormal tetrasacharide. Reviewing the literature, we found 86 reported ALG1‐CDG patients, but only one with normal transferrin analysis.

The experiments were applied to sulfonamides, propranolol, and other organic nitrogen compounds involving aromatic rings from different classes of amine, pyrimidine, and purine with different pKa values (the pKa values for the studied analytes range from 4.6 to 10.4). The results revealed different responses to the different percentages of water addition. Adding 1~2% of water to the modifier (methanol) led to a positive effect manifested by more symmetrical peak shapes and reduced retention times for most compounds. The key factor for this improvement in the properties of chromatographic peaks is due to the adsorption of water on the silanol groups of the stationary phase, consequently resembling the phenomena observed in hydrophilic interaction liquid chromatography (HILIC). Moreover, the availability of hydrogen bond acceptor and donor sites in the analyte structure is an important factor to be considered when adding water as an additive to the modifier for improving the chromatographic peaks. However, introducing water in an amount higher than 3% resulted in perturbed chromatographic signals. It was also found that water as an additive alone could not successfully elute propranolol from the hybrid silica column with an acceptable peak shape; thus, the addition of a strong base such as amine salts was also necessary. The proposed use of a particular amount of water in the mobile phase could have a positive effect compared to the same mobile phase without water, improving the chromatographic peak properties of the elution of some basic organic compounds from the hybrid silica column.}, year = {2024}, eissn = {1420-3049} } @article{MTMT:34834666, title = {Az utazással kapcsolatos védőoltások}, url = {https://m2.mtmt.hu/api/publication/34834666}, author = {Péterfi, Zoltán}, doi = {10.1556/2065.185.2024.5.8}, journal-iso = {MAGYAR TUDOMÁNY}, journal = {MAGYAR TUDOMÁNY}, volume = {158}, unique-id = {34834666}, issn = {0025-0325}, year = {2024}, eissn = {1588-1245}, pages = {651-660}, orcid-numbers = {Péterfi, Zoltán/0000-0001-9658-153X} } @article{MTMT:34833996, title = {A Systematic Review and Meta-Analysis of microRNA Profiling Studies in Chronic Kidney Diseases}, url = {https://m2.mtmt.hu/api/publication/34833996}, author = {Gantsetseg, Garmaa and Bunduc, Stefania and Kói, Tamás and Hegyi, Péter and Csupor, Dezső and Dariimaa, Ganbat and Dembrovszky, Fanni and Meznerics, Fanni Adél and Ailar, Nasirzadeh and Cristina, Barbagallo and Kökény, Gábor}, doi = {10.3390/ncrna10030030}, journal-iso = {NON-CODING RNA}, journal = {NON-CODING RNA}, volume = {10}, unique-id = {34833996}, keywords = {[Meta-analysis]}, year = {2024}, eissn = {2311-553X}, orcid-numbers = {Gantsetseg, Garmaa/0000-0001-9631-8635; Hegyi, Péter/0000-0003-0399-7259; Csupor, Dezső/0000-0002-4088-3333; Dembrovszky, Fanni/0000-0001-6953-3591; Kökény, Gábor/0000-0002-0345-6914} } @article{MTMT:34832995, title = {Changes in the Carotenoids of Zamia dressleri Leaves during Development}, url = {https://m2.mtmt.hu/api/publication/34832995}, author = {Murillo, Enrique and Nagy, Veronika and Menchaca, Dania and Deli, József and Agócs, Attila}, doi = {10.3390/plants13091251}, journal-iso = {PLANTS-BASEL}, journal = {PLANTS-BASEL}, volume = {13}, unique-id = {34832995}, abstract = {It has been observed that the leaves of some Zamia species undergo a kind of “reverse ripening”; that is, they change from their original brown color to green during development. We assumed that this strange color change was due to the change in carotenoid composition, so we followed the changes for several weeks. The detailed carotenoid composition and content at different stages of development of the leaves was determined with HPLC-DAD focusing on the changes in red and yellow carotenoids. The total and relative amounts of red and yellow carotenoids were determined simultaneously from one measurement from a saponified and/or unsaponified extract. At the beginning of development, the concentration of red carotenoids was higher than that of the yellow ones; it decreased drastically until 22 days and continued to decrease slowly until they completely disappeared. The concentration of yellow carotenoids decreased at the beginning as well, but after 22 days it started to increase. The amount of red carotenoids started to decrease when the leaflet stopped growing. Lutein is the main component in old leaflets, which is not a red carotenoid precursor. Red carotenoids can always be found in their esterified form in the leaves. These findings support the hypothesis that red and yellow carotenoid accumulation are independent and probably have different functions in the leaflet. The strange color change was explained based on the compartmentalization of red and yellow carotenoids and on the changing activity of the enzyme capsanthin–capsorubin synthase responsible for the synthesis of red carotenoids capsorubin and capsanthin.}, year = {2024}, eissn = {2223-7747}, orcid-numbers = {Nagy, Veronika/0000-0002-9019-7980; Deli, József/0000-0002-0625-6117} } @article{MTMT:34832790, title = {Case Report: A Sudden Thyroid-Related Death of a 15-Year-Old Girl}, url = {https://m2.mtmt.hu/api/publication/34832790}, author = {Rácz, Kálmán and Simon, Gábor and Kurucz, Andrea and Harsányi, Gergő Tamás and Török, Miklós and Herczeg, László Tamás and Gergely, Péter}, doi = {10.3390/diagnostics14090905}, journal-iso = {DIAGNOSTICS}, journal = {DIAGNOSTICS}, volume = {14}, unique-id = {34832790}, issn = {2075-4418}, abstract = {A 15-year-old young girl was found dead at home.
