Internal Mammary Artery Compression After Pectus Excavatum Repair Does Not Increase Risk of Hemorrhagic Complications in Pediatric Patients

Objectives: Minimal invasive repair of pectus excavatum (MIRPE) described by Nuss is the most popular correction nowadays of this deformity. During the introduction of the bars, they can hurt or compress the internal mammary arteries (IMA). The aim of this study was to observe the prevalence of IMA compression in children after MIRPE. Also, we examined if IMA obstruction increases the risk of complications at bar removal, and if these vascular changes are reversible. Materials and Methods: All patients operated on pectus excavatum in our tertiary pediatric surgical center between 2013 and 2019 were involved in the study. Data of age, sex, number of bars and characteristics of the deformity were examined. IMA flow was checked by Doppler ultrasound (DUS) after MIRPE and after bar removal, too. Results: Among 41 patients with mean age of 15.2 years there were 18 asymmetrical deformities, 23 sternal rotations. Mean pectus index was 4.01. After the Nuss procedure 7(9%) stenoses and 10(12%) occlusions of IMA were found on DUS. After bar removal 3 of 4 stenoses have resolved, but all examined occlusions (3/3) persisted. There were no complications during bar removals. Conclusion: IMA compression after MIRPE in children is uncommon, and is not influenced by severity of deformity. Obstruction of these vessels does not increase the risk of hemorrhagic complications at bar removal. Data of larger cohort are needed to determine reversibility of these changes. © Copyright © 2021 Kovács, Pásztor and Rieth

Effect of freeze-thaw on the texture of gluten-free pie crust dough

Quick frozen food are becoming increasingly popular among consumers in the last decades. During the development of a quick frozen gluten-free pie crust dough product, the aim was to develop a dough that does not suffer any harmful changes after the freeze-thaw process. The texture is one of the most important sensorial properties, and has a great influence on consumer acceptance. Texture Analyser was used to measure the hardness and the brittleness of various doughs. A quick frozen pie crust dough should be easily cut, but non-crumbling after baking. The results showed that the hardness of a dough with 10% more rice flour was bigger than the other dough’s hardness and it became harder after the freeze-thaw process, while the other dough’s hardness have not changed during the process. The first dough was less brittle than the second dough, also before and after the freeze-thaw. In conclusion, the 1st dough is harder, so it is not more easy to cut than the 2nd dough. However, the first dough being less brittle allows cutting with less crumbs. Considering the expectations, in the future the first recipe should be used to make a fast-frozen pie crust dough product

Climatic, hydrological and soil characteristics as a driving force of biological invasion: a case study of Hungary

Invasive plants are a serious threat to biodiversity, biological invasion is a significant problem in protected areas. In order to control their spread, we need to identify the soil, hydrological and climatic conditions which provide favorable conditions for their occurrence. Soil conditions, such as pH level, organic matter and calcium carbonate content and the rooting depth can influence the occurrence of invasive plant species. Many plant species can be associated with surface water, and thus distance from surface water can also be a determining factor for biological invasion. Mean annual temperature and precipitation are climatic factors that can also influence the spread of invasive plants. We mapped the occurrence one of the most aggressively spreading non-native plants of Eurasia (Ailanthus altissima, Asclepias syriaca, Elaeagnus angustifolia, Robinia pseudoacacia, Solidago spp.) in Hungary, using field photos from the EUROSTAT Land Use and Coverage Area Frame Survey (LUCAS) and CORINE Land Cover databases, and investigated with geostatistical methods (ANOVA test in R statistics) how spatial characteristics of infection are related to soil and climatic characteristics and habitat types of Hungary. We found that all the considered soil, hydrological and climatic factor had significant effect for the spread of the investigated invasive plant species. Our results confirm that environmental preference differs between the examined species, climate change may also have a different role on the occurrence

Reciprocal Predictions Between Interest, Self-Efficacy, and Performance During a Task

In this study, we examined how situational interest, self-efficacy, and performance predict each other during task engagement, and how they, in turn, contribute to continued interest. Finnish fourth-graders (N = 263) did a computerized inductive reasoning task consisting of two sections. Before and after each section, the students reported their situational interest and self-efficacy, and at the end of the task, students stated whether they would like to do similar tasks again (i.e., continued interest). Students’ domain-specific interest and self-concept in mathematics, and gender differences were controlled. A cross-lagged reciprocal effects model with repeated measures, control variables, and outcomes within the structural equation modeling framework was estimated. The results showed situational interest to have a stronger effect on self-efficacy than vice versa, and that they both partly contributed to task performance. Continued interest was influenced only by situational interest at the end of the task. The patterning of predictions across the different stages of the task suggests these effects to be somewhat sensitive to task characteristics.</p

Hasi és agyi ultrahang-szűrővizsgálatok Neonatális Intenzív Centrumunkban [Abdominal and cranial ultrasound screenings in our Neonatal Intensive Care Unit]

Bevezetés: A Szegedi Tudományegyetem Neonatális Intenzív Centrumában a korábbi években minden újszülött ellátásának része volt a szűrő jellegű agyi és hasi ultrahangvizsgálat. Célkitűzés: A szűrő ultrahangvizsgálat során diagnosztizált eltérések összesítése, a szűrésként használt ultrahangvizsgálat szükségességének meghatározása. Módszer: A Neonatális Intenzív Centrumunkban 2014. január 1. és 2015. december 31. között elvégzett agyi és hasi ultrahangvizsgálatok eredményeit elemeztük retrospektív módon. A vizsgálatokat radiológus szakorvos végezte. Eltérés esetén a hazaadásig történt kontrollvizsgálatokat, illetve a 2 éves utánkövetést tovább vizsgáltuk. Eredmények: 2 év alatt összesen 579 betegből (átlagos gesztációs kor 34,2 hét [23–41, SD ± 4,04]) 562 (97,1%) esetben történt hasi, 560 (96,7%) újszülöttnél agyi ultrahangvizsgálat, átlagosan a 3,6. életnapon (0–18, SD ± 2,24). A hasi ultrahangvizsgálatok 87%-a (n = 488) szűrő jellegű vizsgálat volt, 140 (29%) esetben találtunk eltérést: pyelectasia (n = 67 [47,9%]), szabad hasi folyadék (n = 17 [12,1%]), köldökvéna-katéter szövődménye (n = 15 [10,7%]), echódús vesék (n = 13 [9,3%]), vesefejlődési rendellenesség (n = 9 [6,4%]), epe, máj, mellékvesék eltérése (n = 14 [10%]). A szűrővizsgálattal felfedezett vesefejlődési rendellenességek közül 4 esetben (0,8%) műtéti beavatkozás volt szükséges. A vesét érintő elváltozások fiú (p = 0,18) és bal oldali (p = 0,54) dominanciát mutattak. Az agyi ultrahangvizsgálatok 65%-a (n = 362) volt szűrővizsgálat, 51 (14%) újszülöttnél találtunk eltérést: plexuscysta (n = 21 [41%]), plexusvérzés (n = 9 [17,6%]), enyhe kamraaszimmetria (n = 8 [15,7%]), subependymalis vérzés (n = 5 [9,8%]), a periventricularis terület eltérése (n = 4 [7,8%]), colpocephalia, thalamusgóc, hydrocephalus externus, echódús meninx (n = 1-1 [1,9-1,9%]). Következtetés: A szűrő hasi ultrahangvizsgálat által észlelt eltérések közül a beavatkozást igénylő vesefejlődési rendellenességek, illetve a köldökvéna-katéter szövődményei bírnak klinikai jelentőséggel. Bár a legmagasabb számban enyhe pyelectasia került felismerésre, 4 vesefejlődési rendellenesség műtéti beavatkozást igényelt. További vizsgálatok szükségesek a rizikócsoportok meghatározására, amivel az egy pozitív találatra jutó szűrendő esetek száma csökkenthető volna. Az agyi ultrahang-szűrővizsgálat nem talált intrauterin, még nem diagnosztizált, beavatkozást igénylő eltérést. A szűrő agyi ultrahangvizsgálat által észlelt eltérések nem teszik indokolttá az univerzális agyi ultrahang-szűrővizsgálat végzését. Orv Hetil. 2023; 164(31): 1222–1230

Estimation of agro-ecosystem services using biogeochemical models

Agro-ecosystem services are the various benefits (e.g., crop yield) that people freely obtain from the properly functioning agricultural lands. The estimated changes in climatic conditions including increasing temperature, with particular attention to the summer means, together with the expected changes in the temporal precipitation distribution pose enormous challenge to the agriculture. Currently, dynamic system models are most frequently used tools that are capable of estimating the prospective effects of climate change on agro-ecosystems. A deterministic biogeochemical model is presented that is developed by Hungarian scientists within the framework of the AgroMo project. The main goal of the AgroMo project is to develop climate-smart strategies in order to mitigate the effect of potential future hazards in the context of climate change by 1) creating a complex, state-of-the-art experimental platform; 2) producing ten new, 0.1° spatial resolution climate scenarios based on the RCP (Representative Concentration Pathway) 4.5 and RCP8.5 scenarios; 3) developing an integrated assessment and modeling framework that is capable of simulating every major land use types; 4) analyzing/simulating a great number of adaptation strategies that can be used to support decision makers. Based on the preliminary simulation results, climate change will most likely expose significant negative impact on the spring sown crops in Hungary. Although, the yield losses could be avoided with irrigation or could be mitigated with earlier sowing, the role of winter crops is likely to become more significant in Hungary in the future
