Authors: PUŠ Tamara , PODGRAJŠEK Ksenija , SIMČIČ Marjan
Published: December 2023

Accurate assessment of nutrient intake of the population represents one of the main challenges in food and nutritional science. Evaluation of food diary is a complicated process, involving choosing the appropriate nutritional database and having well qualified personnel (coders) to work with it. The aim of this study was a comparison of nutrient intake data obtained from one weighed 5-day food diary processed by five master degree students, studying nutrition, focusing on coding errors. Nutrition evaluation was done by Prodi 5.7 Expert Plus computer programme and IBM SPSS Statistics 20 for statistical analysis. Results of our pilot study show that variability of calculated data induced by food coding lonesome is acceptable. Nevertheless putting other errors into account, results can be misleading. On a five-day level macronutrients intake variability is between 5 and 15%, while energy intake variability is within 6%. Uncommon food items and complex composition of the meal have the major impact on observed high standard deviations on a separate meal level. In conclusion the main reason of food coding errors is inaccuracy and incorrect identification of specific food items.

Authors: SAEED AWAN Muhammad , HUSSAIN Azhar , ABBAS Tanveer , KARIM Rehmat
Published: December 2023

The primary data used for the investigation were obtained through a questionnaire. One hundred and twenty (120) farmers were randomly selected; their education level, area of cultivation, time of planting, intercropping, varieties grown, fertilizer used, time of picking, packing, transportation and processing were looked at. It was found that out of 120 respondents, 52% were literate, and 48% were illiterate. 90% land holders were owners while remaining were tenants. Roma variety (46%) was preferred variety followed by Rio-Grind (38%) and Heirloom variety (16%). In terms of picking time, majority of farmers picked tomatoes in the afternoon (38%) or evenings (34%) and rest picked them in the mornings (28%). All the farmers transported tomatoes to local market either in wooden boxes (76%) or traditional baskets (24%). Majority of the farmers responded positively to drying tomato, but (27%) were unaware of processing procedures. Over all loss of tomato crop to fungal and viral diseases was estimated to be 24%.
Kaparji (Hemiptera: Coccoidea) vinske trte (Vitis vinifera L.) v Sloveniji in možnosti njihovega biotičnega zatiranja

Published: December 2023

V Sloveniji se na vinski trti pojavljajo kaparji Neopulvinaria innumerabilis, Pulvinaria vitis, Parthenolecanium corni in Planococcus ficus. Te žuželke sesajo rastlinski sok in povzročajo prezgodnje odpadanje listov in bolezenske okužbe grozdov, kar vpliva na kakovost pridelka. Kaparji so tudi pomembni prenašalci rastlinskih virusov. Vrsti P. vitis in P. corni sta razširjena po vsej Sloveniji, vrsta N. innumerabilis v vinogradih na Primorskem, vrsto P. ficus pa največkrat najdemo v zavarovanih prostorih. Običajno kaparje zatiramo z uporabo insekticidov, vendar so sodobne strategije varstva rastlin usmerjene v naravi prijaznejše načine, kot sta mehansko in biotično zatiranje škodljivcev. Pri nas biotično zatiranje kaparjev še ni dobro raziskano, čeprav se je v srednji Evropi že izkazalo za uspešno.
Genska banka trpežne ljuljke in črne detelje v Sloveniji
Authors: ČOP Jure
Published: December 2023

V slovensko rastlinsko gensko banko sta poleg drugih kulturnih rastlin vključeni tudi trpežna ljuljka in črna detelja. V prispevku so prikazani: kratka zgodovina genske banke trav in metuljnic na Biotehniški fakulteti v Ljubljani, ex situ zbirka ekotipov trpežne ljuljke in črne detelje, delo in izbrani rezultati karakterizacije in evalvacije. Organizirano delo pri genski banki trpežne ljuljke in črne detelje poteka od leta 1989. Zbranih je 71 ekotipov trpežne ljuljke in 104 ekotipi črne detelje. Zaradi tradicionalne in lokalno pogojene rabe naravnega travinja in različnih ekoloških razmer obstaja še precej možnosti za nadaljnje zbiranje ekotipov teh dveh vrst. Nabirajo se semena z manjših travnih površin, začasno izločenih iz pridelave krme. Pri ekstenzivni rabi ta izločitev ni potrebna. Razmnoževanje obeh vrst poteka ob ustrezni izolaciji populacij pred tujim cvetnim prahom. Pri črni detelji je potrebna tudi uporaba čmrljev. Ekotipi trpežne ljuljke in črne detelje se med seboj in od sort značilno razlikujejo v morfoloških in agronomskih lastnostih. V teh lastnostih so enkrat bolj, drugič pa manj izenačeni od sort. Po kakovosti glede merjenih agronomskih lastnostih le nekateri ekotipi dosegajo standardne sorte.

Published: December 2023

V stoletjih pridelovanja so se v Sloveniji razvile številne avtohtone sorte vrtne solate (Lactuca sativa L.). Z zbiranjem, ki je od začetka devetdesetih let prejšnjega stoletja potekalo po Sloveniji, smo do danes zbrali skupno 177 genskih virov, ki jih v okviru Slovenske rastlinske genske banke (SRGB) hranimo in vzdržujemo na Kmetijskem inštitutu Slovenije. Zbirka vsebuje tudi nekatere divje sorodnike vrtne solate in genske vire, ki smo jih za namene raziskovalnega dela pridobili iz drugih genskih bank v Evropi in svetu. Skupaj obsega 227 genskih virov. V okviru raziskovalnih projektov smo večji del zbirke podrobno ovrednotili z morfološkimi in molekulskimi markerji. Pretežni del zbirke predstavljajo krhkolistne solate, najbolj zastopana med njimi je avtohtona sorta 'Ljubljanska ledenka', kateri smo v zadnjih letih namenili posebno pozornost, saj ji je grozilo izumrtje. Na osnovi večletnega vrednotenja izbranih virov 'Ljubljanske ledenke' tako iz SRGB kot iz drugih genskih bank v svetu smo ugotovili, da še obstojajo genski viri, ki ustrezajo originalnemu opisu sorte in se hkrati razlikujejo od do sedaj znanih sort. Te vire smo uporabili za obuditev sorte 'Ljubljanska ledenka' in sorto bomo kot avtohtono vpisali v Sortno listo.
Prehranske potrebe oslov in njihove najpogostejše s prehrano povezane bolezni

Published: December 2023

Število rejcev oslov v Sloveniji in ostalem razvitem svetu v zadnjih letih narašča. Osli so bili v preteklosti pomembne gospodarske živali, ki so jih za delo uporabljali predvsem na območjih z malo krme. Ker so manj zahtevni in bolj vzdržljivi, so pogosto nadomeščali konje, danes pa so predvsem ljubiteljske živali in jih v razvitem svetu za delo večinoma ne uporabljajo. Osli in konji imajo skupne značilnosti, vendar pa so med njimi tudi pomembne razlike, ki jih ne smemo spregledati. Ena od pomembnejših razlik je način prehranjevanja in sestava obroka. Osli so se razvojno prilagodili suhim območjem podsaharske Afrike in lahko preživijo ob skromni krmi, ki ima malo energije, vsebuje malo beljakovin in veliko vlaknine. Prav zato jih moramo v našem okolju krmiti pazljivo, da ne postanejo predebeli in obolijo za številnimi, z debelostjo povezanimi boleznimi. Premalo gibanja, energijsko prebogata krma in pomanjkanje normativov v zvezi s prehrano, ki so večinoma povzeti iz normativov prirejenih za konje, so poglavitni vzroki pogostega pojavljanja debelosti pri oslih. V preglednem članku bomo predstavili značilnosti prehrane, prebave in presnove oslov, njihove potrebe po energiji in hranilnih snoveh v primerjavi s konji ter osnovne prehranske bolezni, ki se pojavijo zaradi preobilnega krmljenja: hiperlipidemija, laminitis in metabolni sindrom kopitarjev.

This work presents a pH control approach, robust to model uncertainties including the scaling-up process. The algorithm is based on a master-slave synchronization, where the real process is taken as the slave, and the master is generated by the real-time simulation of the closed-loop mathematical model of the process. In that sense, the objective is to control the pH value, under minimal process information and subject to perturbations and time-varying references ranging between the basic and acid regions, at laboratory and industrial scales.

Published: December 2023

Objectives

To compare the frequency of Ureaplasma-positive gastric fluid (GF) cultures based on the cause and mode of delivery in preterm newborns.

Methods

This retrospective cohort study included women with a singleton pregnancy who delivered prematurely (between 23+0 and 32+0 weeks of gestation, n=464) at a single university hospital in South Korea. The newborns’ GF was obtained on the day of birth via nasogastric intubation. The frequency of Ureaplasma spp. in GF cultures was measured and compared according to the cause and mode of delivery.

Results

Ureaplasma spp. was detected in 20.3 % of the GF samples. The presence of Ureaplasma spp. was significantly higher in the spontaneous preterm birth group than in the indicated preterm birth group (30.2 vs. 3.0 %; p<0.001). Additionally, Ureaplasma spp. was more frequently found in the vaginal delivery group than in the cesarean delivery group, irrespective of the cause of preterm delivery [indicated preterm birth group (22.2 vs. 1.9 %, p=0.023); spontaneous preterm birth group (37.7 vs. 24.2 %, p=0.015)].

Conclusions

Ureaplasma spp. were found in 20.3 % of the GFs. However, only 1.9 % of newborns in the indicated preterm birth group with cesarean delivery had a Ureaplasma-positive GF culture.
Mitochondrial genetic variation in long-eared hedgehogs, Hemiechinus auritus, from the Anatolian Peninsula and Cyprus
Authors: Özmen Medine , Demirtaş Sadık , Herman Jeremy S. , Gündüz İslam
Published: December 2023

Mitochondrial genetic variation was examined in long-eared hedgehogs, Hemiechinus auritus, from the Anatolian Peninsula, the adjacent island of Cyprus and from Azerbaijan. These data were compared with those available from other parts of the species’ range in North Africa and Asia. Two distinct cytochrome-b lineages are present in Anatolia, one of them previously unknown. The lineage found in south-eastern Anatolia has previously been identified in Egypt and is likely present around the eastern coast of the Mediterranean. The close relationship between haplotypes from Cyprus and those from Egypt suggests that the island was colonised from North Africa, or perhaps the Middle East, rather than Anatolia. The new lineage, which can be referred to the subspecies H. a. calligoni, was only found in the extreme eastern part of Anatolia and may have been isolated from neighbouring lineages to the south-west and to the east by the Taurus and Caucasus mountain ranges, respectively.

The goal of this paper is to show that 11, 33, 55, 88 and 99 are all repdigits expressible as sum or difference of two k-Pell. The proof of our main theorem uses lower bounds for linear forms in logarithms of algebraic numbers and a modified version of Baker-Davenport reduction method (due to Dujella and Pethő). This extends a result of Bravo and Herrera [Repdigits in generalized Pell sequences, Arch. Math. (Brno) 56(4) (2020), 249–262].

In this work, we study the integration of the differential-difference sine-Gordon equation with an integral type source. We deduce the time performance of the scattering data of the spectral problem which is associated with the discrete sine-Gordon equation. Using the inverse scattering method, we integrate the Cauchy problem for the differential-difference sine-Gordon equation with the integral type source in the class of the rapidly decreasing functions.

Published: December 2023

In recent years, alternative approaches have been implemented in the automotive sector to reduce raw material costs and protect the environment. An increase in weight causes both fuel consumption and CO2 emissions to rise. This study aims to reduce exhaust emissions due to weight reduction by using foamed polypropylene in the door panel production of a subcompact crossover SUV car and saving energy by shortening the injection cycle time. The newly produced 2 % ITP 822 chemical foaming agent added door panel was compared with the current door panel performances. As a result of foam morphology structure, impact, and hardness tests, it was decided that ITP 822 is a suitable chemical foaming agent. In addition, a weight reduction of 5.2 % was achieved. Moreover, the injection cycle time has been reduced by approximately 12 %, reducing the total cycle time from 35 s to 31 s.

Published: December 2023

Polarized light has promising applications in biological inspections, displays, and precise measurements. Direct emission of polarized light from a semiconductor device is highly desired in order to reduce the size and energy-consumption of the whole system. In this study, we demonstrate a semipolar GaN-based microcavity light-emitting diode (MCLED) that could simultaneously produce green light with perpendicular and parallel polarizations to the c*-axis. Orthogonally polarized emission with a narrow linewidth (∼0.2 nm) arises from the valence band splitting and birefringent nature of the semipolar GaN material, as well as the mode selection of the resonant cavity. By modulating the cavity length, the device is capable of switching between single- and multi-mode emission spectra. We believe that the approach of employing a cavity structure and semipolar GaN can be extended to produce orthogonally and linearly polarized blue, red, and violet light by adjusting the material compositions.

Published: December 2023

This paper discusses the integration of artificial intelligence (AI) tools in education, delineating their potential to transform pedagogical practices alongside the challenges they present. Generative AI models like ChatGPT, had a disruptive impact on teaching and learning, due to their ability to create text, images, and sound, revolutionizing educational content creation and modification. However, nowadays the educational community is polarized, with some embracing AI for its accessibility and efficiency thus advocating it as an indispensable tool, while others cautioning against risks to academic integrity and intellectual development. This document is designed to raise awareness about AI tools and provide some examples of how they can be used to improve education and learning. From an educator’s perspective, AI is an asset for curriculum development, course material preparation, instructional design and student assessment, while reducing bias and workload. For students, AI tools offer personalized learning experiences, timely feedback, and support in various academic activities. The Turkish Biochemical Society (TBS) Academy recommends educators to embrace and utilize AI tools to enhance educational processes, and engage in peer learning for better adaptation while maintaining a critical perspective on their utility and limitations. The transfer of AI knowledge and methods to the teaching experiences should complement and not replace the educator’s creativity and critical thinking. The paper advocates for an informed embrace of AI, AI fluency among educators and students, ethical application of AI in academic settings, and continuous engagement with the evolving AI technologies, ensuring that AI tools are used to augment critical thinking and contribute positively to education and society.
Mental stress and resources in the sectors of IT services and social services – The potential of company occupational safety and health policy for developing health-promoting organisations
Authors: Becke Guido , Gerdau-Heitmann Cornelia , Zenz Cora , Koppelin Frauke , Mümken Sarah
Published: December 2023

The COVID-19 pandemic greatly increased the demands on employees and companies for handling mental stress and resources. A mixed-methods design was used to examine contrasting occupational groups, i. e. IT service workers (IT), and care workers and home helps providing social care (SC) in clients’ homes. First, this paper analyses how the mental health of both occupational groups was affected by the pandemic. Second, the potential of risk assessments for mental health (RA-M) for developing health-promoting organisations is investigated. While the first question is analysed with quantitative company surveys before and during the pandemic, the second question draws on qualitative company case studies.

The quantitative survey shows few differences in health outcomes for the occupational groups during the observation period. In contrast to social care employees, IT employees were able to work at home. The social care employees show a greater fear of infection and report little influence over their work. In IT, the lack of direct contact with colleagues was perceived as stressful, while improvements in work autonomy were reported.

The case study findings show that implementing RA-M contributed to reducing work-related stress and to fostering health-related resources. RA-M-based workplace interventions proved to be overarching social innovations that extended beyond OSH by improving work structures and enabling health-sensitive organisational development.
Managing pastoral landscapes: remote survey of herding infrastructure in Huancavelica, Peru
Authors: Whitlock Bethany , Van Valkenburgh Parker , Wernke Steven A.
Published: December 2023

Recent archaeological research in the Andes suggests that Indigenous herders carefully managed their environments through the modification of local hydrology and vegetation. However, the limited geographical scale of previous research makes it challenging to assess the range and prevalence of pastoralist land management in the Andes. In this article, the authors utilise large-scale, systematic imagery survey to examine the distribution and environmental contexts of corrals and pastoralist settlements in Huancavelica, Peru. Results indicate that corrals and pastoralist settlements cluster around colonial and present-day settlements and that a statistically significant relationship exists between pastoral infrastructure and perennial vegetation. This highlights the utility of remote survey for the identification of trans-regional patterns in herder-environment relationships that are otherwise difficult to detect.
incertitude face au télétravail et ses effets sur la satisfaction au travail : les rôles de la fatigue au changement et du soutien organisationnel perçu
Authors: Lauzier Martin , Desjardins Guillaume , Memettre Johnny
Published: December 2023

En contexte de changement, la préoccupation principale devrait être de réduire l’incertitude. Considérant le contexte inusité occasionné par la pandémie de COVID-19 sur les organisations, et la nouveauté certaine du télétravail pour bon nombre d’entre elles, il importe de mieux saisir les effets que peut entraîner ce mode d’organisation du travail – en tant que changement – sur le bien-être, voire la satisfaction des employés. S’appuyant sur la Théorie de la conservation des ressources et la Théorie du soutien organisationnel perçu, cette étude explore le lien entre l’incertitude face au changement et la satisfaction au travail. Au total, 376 personnes ont participé à l’étude en remplissant un questionnaire électronique administré au moment de la deuxième vague de la COVID-19 (c.-à-d. au début de l’hiver 2021). Trois principaux résultats se dégagent de cette étude. Premièrement, l’incertitude à l’égard du télétravail semble négativement liée au niveau de satisfaction déclaré par les télétravailleurs. Deuxièmement, le niveau de fatigue à l’égard du changement déclaré par les télétravailleurs constitue un mécanisme médiateur entre l’incertitude et la satisfaction. Enfin, ces résultats montrent aussi le rôle modérateur du soutien organisationnel perçu sur la relation unissant la fatigue liée au changement à la satisfaction au travail. Globalement, l’effet de la fatigue combiné à l’absence de soutien engendre un plus faible niveau de satisfaction chez les télétravailleurs.
Stratégie de qualité de vie au travail d’organisations publiques québécoises : identification des parties prenantes, de leur rôle et de leurs raisons
Authors: Tornare Jessica , Rinfret Natalie
Published: December 2023

De nos jours, la qualité de vie au travail (QVT) suscite un intérêt croissant tant par les coûts humains et financiers que son absence peut engendrer que par les bénéfices qu’elle peut apporter. Au sein du secteur public, les nombreuses réformes entreprises ces dernières décennies se sont traduites par une intensification du travail et une détérioration de la QVT. Des facteurs qui ne concourent pas à aider les organisations publiques à faire face aux défis qui leur sont propres, notamment en matière de gestion du changement. En réponse à ces enjeux, certaines organisations ont accompagné leurs changements organisationnels par la mise en place de stratégies d’amélioration de la QVT qui vont au-delà du respect des contraintes légales ou réglementaires. Alors que les recherches se concentrent principalement sur l’analyse de la QVT au niveau de l’individu, cette étude qualitative s’appuie sur la théorie des parties prenantes pour mieux comprendre et explorer les stratégies de QVT au sein d’organisations publiques québécoises. Les données, issues de 33 entretiens semi-dirigés et de documents internes et externes, ont été collectées auprès de 3 organisations. Les résultats permettent d’identifier les parties prenantes impliquées dans ces stratégies de QVT, et d’analyser leur rôle et leurs raisons. Ils soulignent que l’État employeur ne devrait pas faire l’économie d’une réflexion quant aux parties prenantes et aux raisons d’implantation d’une stratégie de QVT, ainsi qu’au rôle du Secrétariat du Conseil du trésor dans l’établissement et l’accompagnement de telles stratégies, et dans la gestion du changement y afférant.
influence de la COVID-19 sur les changements organisationnels dans l’appréciation du télétravail par les travailleurs
Authors: Truchon Audreyanne , Hamouti Rhizlane
Published: December 2023

La pandémie de COVID-19 a pris tout le monde par surprise. Que ce soit sur le marché du travail ou dans d’autres sphères d’activité, les impacts ont été déterminants pour tout un chacun. Nous constatons toutefois, dans cette recherche, que non seulement le télétravail en tant que changement organisationnel a eu droit à une avancée fulgurante, mais qu’également, les impacts positifs se sont fait sentir concrètement dans la vie professionnelle et personnelle des gens. La littérature nous propose déjà une panoplie d’articles démontrant les enjeux, les avantages, l’historique de ce concept de travail, mais aucun n’étudie le travailleur dans ce contexte. Le sujet central de notre étude est de placer l’accomplissement des télétravailleurs au coeur des éléments clés de ce changement organisationnel afin de mesurer les impacts, favorables ou défavorables, qu’il suscite. Par l’analyse des résultats, nous voulons démontrer par plusieurs aspects tels que la rémunération, la performance au travail, les ambitions professionnelles des télétravailleurs, la conciliation travail-famille–vie personnelle, la réalisation de soi, le sentiment d’appartenance, l’avancement professionnel et la motivation au quotidien, si la population au Québec considère le télétravail comme un accélérateur à leur accomplissement personnel et professionnel. Les résultats démontrent qu’il existe un lien fort entre ce changement organisationnel imprévu et forcé. Les gens expriment une grande satisfaction à inclure ce nouveau mode de travail à leur quotidien et souhaitent qu’il s’inscrive de manière pérenne dans l’organisation du travail.
Comment changer? Quelques pistes de réflexion d’un point de vue syndical
Authors: Gagné Diane , Lemieux Dominic
Published: December 2023

De nouvelles opportunités s’offrent au mouvement syndical. La rareté de la main-d’oeuvre et la situation économique (inflation) procurent une conjoncture favorable aux organisations syndicales leur permettant de regagner du terrain perdu. De plus, outre la récente décision de la Cour d’appel du Québec concernant les travailleurs et travailleuses étudiants d’ABI - qui reconnait que ceux-ci ne peuvent pas être payés moins pour accomplir des tâches équivalentes - de récents changements législatifs rendent plus difficiles l’adoption de clauses de disparité de traitement et commandent l’obligation d’une rémunération équivalente pour les travailleurs et travailleuses d’agence. Reconnaissant la nécessité du changement organisationnel, thématique de ce numéro, pour les différentes parties prenantes du monde du travail, les auteur.es posent alors cette question : comment les organisations syndicales pourraient saisir l’occasion qui se présente? Dit autrement, comment pourraient-elles contribuer à réduire la précarité en emploi tout en assurant la pérennité des organisations ? Après cinq décennies de « vent de face », les astres sont alignés pour que le mouvement syndical reprenne l’offensive et travaille à renverser la vapeur de la précarisation du travail, Pour se faire, il faut sortir du carcan de leur corporatisme syndical, et surtout ne pas « surfer » sur la satisfaction des membres. Il faut au contraire des actions d’éducation, de mobilisation et de sécurisation, afin de contrer la précarisation du marché du travail. Cette conjoncture favorable doit aussi bénéficier aux travailleurs et travailleuses précaires, une telle opportunité ne se représentera pas souvent!
sécurité psychologique au travail : une perspective théorique
Authors: Maillet Stéphanie , Marcoux Gilles
Published: December 2023

Un nombre croissant de travaux se sont consacrés à la compréhension de la sécurité psychologique au travail, à l’identification des facteurs qui y contribuent et à l’examen de ses répercussions sur les individus, les équipes et les organisations. Toutefois, à notre connaissance, il n’existe aucune documentation en français qui fournit un aperçu de la littérature existante en matière de sécurité psychologique au travail. Cet article à perspective théorique vise donc à combler cette lacune en introduisant un bilan des connaissances actuelles sur le contexte et les définitions de la sécurité psychologique, ses bienfaits, ses déterminants, ainsi que les conditions (dé)favorables à la sécurité psychologique. Cet article suggère également des approches d’intervention pratique et propose de nouvelles pistes de recherche en ce qui a trait à la sécurité psychologique au travail.
Making Connections: Neurodevelopmental Changes in Brain Connectivity after Adverse Experiences in Early Adolescence
Authors: Pollmann Ayla , Sasso Remo , Bates Kathryn , Fuhrmann Delia
Published: December 2023

Adverse childhood experiences have been linked to detrimental mental health outcomes in adulthood. This study investigates a potential neurodevelopmental pathway between adversity and mental health outcomes: brain connectivity.

This study used data from the prospective, longitudinal Adolescent Brain Cognitive Development study (ABCD, N ≈ 12.000, participants aged 9-13, male and female) and assessed structural brain connectivity using fractional anisotropy (FA) of white matter tracts. The adverse experiences modelled included family conflict and traumatic experiences. K-Means clustering, and Latent Basis Growth Models (LBGM), were used to determine subgroups based on total levels and trajectories of brain connectivity. Multinomial regression was used to determine associations between cluster membership and adverse experiences.

Results showed that higher family conflict was associated with higher FA levels across brain tracts (e.g.,t(3) = -3.81,β= -0.09,pbonf= .003) and within the corpus callosum (CC), Fornix and anterior thalamic radiations (ATR). A decreasing FA trajectory across two brain imaging timepoints was linked to lower socioeconomic status and neighbourhood safety. Socioeconomic status was related to FA across brain tracts (e.g.,t(3) = 3.44,β= 0.10,pbonf= .01), the CC and the ATR. Neighbourhood safety was associated with FA in the Fornix and ATR (e.g.,t(1) = 3.48,β= 0.09,pbonf= .01).

There is a complex and multifaceted relationship between adverse experiences and brain development, where adverse experiences during early adolescence are related to brain connectivity. These findings underscore the importance of studying adverse experiences beyond early childhood to understand lifespan developmental outcomes.

Significance statementThere is a compelling link between youth adversity and various detrimental outcomes, including reduced mental health, socioeconomic status, and even life expectancy. One potential pathway for the lifelong consequences of adversity could be neurodevelopment in adolescence, but few studies have tested this directly. This study investigates a potential neurodevelopmental pathway between adversity and mental health outcomes: brain connectivity. We explored the relationship between adverse experiences during early adolescence (ages 9-13) and individual differences in neurodevelopmental trajectories. Our results provide novel evidence demonstrating that adverse experiences during adolescence are related to changes in brain connectivity. They highlight the need to consider environmental influences on development during adolescence, a unique period of protracted biological, social, and cognitive changes.

Background: Glycated haemoglobin (HbA1c) measurement is used for diagnosis, management and remission of type 2 diabetes (T2DM), with measurements comparable worldwide and the World Health Organization listing medical conditions that affect its accuracy. Admission glucose is in the ‘diabetes’ range in 5% of emergency hospital admissions without prior diagnosis, with literature searches indicating inconsistent practice on using HbA1c to confirm diagnosis. As oral glucose tolerance tests (OGTT) were not possible during the COVID-19 pandemic, guidance was issued by the Royal College of Obstetrics and Gynaecology on using HbA1c for gestational diabetes mellitus.
Aims: This study explores use of HbA1c at Queen Elizabeth Hospital Birmingham, a large university hospital serving a multi- ethnic adult population.
Methods: Information is presented on comparability, clinical audits, research studies and current practice, and is illustrated by case reports.
Results: Data from the National Glycohemoglobin Standardization Program show comparability of laboratoryHbA1c and point-of-care testing methods from 1993 to 2023. Although HbA1c was used to diagnose gestational diabetes during the COVID-19 pandemic, hospitals have reverted to OGTT post pandemic. In contrast, HbA1c is now being used to assess T2DM remission. Case reports illustrate these scenarios and highlight the complexity of decision-making when the accuracy of the HbA1c reading is affected by multiple co- morbidities.
Conclusions: This wider use of HbA1c includes remission of T2DM but the diagnosis of gestational diabetes has reverted to OGTT post pandemic. A pictorial representation of HbA1c range is presented to aid understanding of this test. It is suitable for diagnosis of diabetes in most people except those with some variant haemoglobins or abnormal red blood cell turnover.

Authors: YEŞİLDAŞ Cansu , KANAT Burcu
Published: December 2023

Amaç: Bu çalışmanın amacı; farklı sinterizasyon yöntemlerinin ve blok renginin monolitik zirkonya ile adeziv rezin siman arasındaki makaslama bağ dayanımı üzerindeki etkilerinin incelenmesidir.

Gereç ve Yöntemler: Kendinden renkli (InCoris TZI C A2, Sirona) (CZ) ve renksiz (InCoris TZI, Sirona) (Z) monolitik zirkonya blokları, sinterizasyon sonrası 4mm×4mm×4mm boyutlarında olacak şekilde küpler halinde kesildi (N=40). Renkli ve renksiz örnekler, konvansiyonel sinterizasyon (KS) ve hızlı sinterizasyon (HS) olmak üzere 2 alt gruba ayrıldı (n=10). Akrilik içerisinde sabitlenen örnekler kumlandıktan sonra primer uygulandı. Adeziv rezin siman (çap:2mm, yükseklik:2mm) şekillendirildi ve polimerize edildi. Makaslama bağ dayanım (SBS) testinin (Bisco, ABD, 0.5 mm/dk) uygulanması ile elde edilen verilerin istatistiksel analizi (SPSS 26, 2-yönlü ANOVA, bağımsız t-testi) gerçekleştirildi (p=0.05). Kırık tipleri sınıflandırıldı.

Bulgular: En yüksek SBS değeri KS-Z (25.13±8.47) grubunda, en düşük SBS değeri ise HS-Z (14.89±7.08) grubunda gözlendi. SBS değerleri üzerinde sinterizasyon yöntemlerinin istatistiksel açıdan anlamlı etkisi bulunurken (p=0.006) monolitik zirkonyanın renkli olma özelliğinin anlamlı etkisi görülmedi (p>0.05). Renksiz bloklarda, KS (25.13±8.47) grubunda HS (14.89±7.08) grubuna göre istatistiksel olarak yüksek değerler bulundu (p=0.009). Renkli bloklarda ise HS (17.99±5.21) ve KS (20.89±7.31) grupları arasındaki farkın istatistiksel açıdan anlamlı olmadığı görüldü (p>0.05). Hem hızlı hem de konvansiyonel sinterizasyonda ise Z ve RZ grupları arasında anlamlı bir farklılık bulunmadı (p>0.05).

Sonuç: Farklı sinterizasyon yöntemlerinin, renksiz monolitik zirkonya bloklar ile adeziv siman arasındaki makaslama bağ dayanımını etkilerken renkli monolitik zirkonya bloklar ile adeziv rezin siman arasındaki makaslama bağ dayanımını etkilemediği bulundu. Blokların önceden renklendirilmiş veya renklendirilmemiş olması, monolitik zirkonya ile adeziv siman arasındaki makaslama bağ dayanımını etkilemedi.

Published: December 2023

Amaç: Bu çalışmanın amacı, avülsiyonun acil müdahalesinde Türkçe YouTube™ videolarının hasta bilgi kaynağı olarak, içerik ve kalitesinin değerlendirilmesidir.

Gereç ve Yöntemler: YouTube™ videolarının değerlendirilmesi için ‘avülsiyon, diş travması, diş yaralanmaları ve dişin yerinden çıkması’ anahtar kelimeleri kullanıldı. Videolar dahil edilme ve hariç tutulma kriterlerine göre titizlikle incelendi. Seçilen videoların içerikleri, Uluslararası Dental Travmatoloji Derneği’nin son tedavi rehberinin avülsiyon yaralanmalarında uygulanması gereken önermelere göre, 9 puanlık bir yararlılık skoru ile puanlandı. Yararlılık skoruna göre video içeriği; zayıf (0-3), orta (4-6) ve mükemmel (7-9) şeklinde üç gruba ayrıldı. Videoların kalitesinin değerlendirilmesinde, videoların genel kalitesini derecelendiren Küresel Kalite Ölçeği (GQS) kullanıldı. Videoların güvenilirliği DISCERN güvenirlik aracına göre puanlandı. İstatistiksel analizler yapıldı.

Bulgular: Toplam 240 video analiz edildi ve dahil edilme kriterlerine uyan 33 video çalışmaya dahil edildi. Video yükleme kaynağının en çok özel klinik/özel hastaneler olduğu (% 36.4; n=12), fakat bu kuruluşlar tarafından yüklenen videoların çoğunun zayıf içerikli olduğu görüldü (% 66.7; n=8). Videoların hedef kitlesinin çoğunlukla hastalar (% 78.8; n=26) olduğu görüldü. Videoların yararlılık skoruna göre, % 45.5’i zayıf, % 30.3’ü orta ve % 24.2’si mükemmel olarak sınıflandırıldı.

Sonuç: YouTube™ genellikle avülse dişlerin yönetimi ile ilgili düşük yararlılığa sahip videolar sunmaktadır. Bu nedenle, diş hekimleri bu kaynağın farkında olmalı ve hastaları/ebeveynleri YouTube™ videolarındaki bilgilerin güvenilirliği ve yanıltıcı içerik barındırabileceği konusunda uyarmalıdır.

The aim of the study. To study the effect of high nitric oxide concentrations on hollow polypropylene fibers of oxygenators.

Materials and methods. The study was conducted in two stages. At the first stage, we evaluated the stability of oxygenator membrane made of hollow polypropylene fibers after six hours of exposure to air-oxygen mixture containing NO at 500 parts per million, or 500 pro pro mille (ppm) concentration, using mass spectrometry and infrared spectroscopy. At the second stage, an experiment with cardiopulmonary bypass (CPB) was conducted on 10 pigs. In the study group (n=5) animals sweep gas was supplied to the oxygenator as an air-oxygen mixture with NO at 100 ppm. In the control group animals (n=5) an air-oxygen mixture was used without NO. The CPB lasted for 4 hours, followed by observation for 12 hours. NO, NO2 (at the inlet and outlet of the oxygenator), and the dynamics of methemoglobin were evaluated. After weaning of animals from CPB, the oxygenators were tested for leakproofness, and scanning electron microscopy (SEM) was performed.

Results. The oxygenator made of polypropylene hollow fibers retained its gas transfer parameters after six hours of exposure to air-oxygen mixture containing NO at 500 ppm. Based on IR-Fourier spectroscopy findings, NO did not affect structural integrity of polypropylene membranes. NO added to gas mixture at 100 ppm did not increase NO2 to toxic level of 2 ppm in 91% of control tests during 4 hours CPB in pigs; mean value was 1.58 ± 0.28 ppm. Methemoglobin concentration did not exceed the upper limit of permissible level (3%), and there were no statistically significant differences with the control group. All tested oxygenators have passed the leakproofness test. According to SEM findings, larger amounts of fibrin deposits were found in the control group oxygenators vs study group.

Conclusion. There were no negative effects of NO at 500 ppm concentration on the oxygenator membrane made of hollow polypropylene fibers. NO at 100 ppm in a gas-mixture supplied to oxygenators did not lead to an exceedance of safe NO2 and methemoglobin concentrations in an animal model. Reduced fibrin deposits on hollow fibers of polypropylene oxygenator membranes were observed when with NO at a level of 100 ppm was added to a gas mixture.
The Green Asset Ratio – same same but different?
Authors: Müller-Dethard Jan , Petras Matthias
Published: December 2023

The green asset ratio (GAR) is supposed to be the central indicator for the taxonomy alignment of the bank’s assets. However, we show that GARs may differ for one and the same bank between article 8 taxonomy reporting and pillar 3 disclosures, leading effectively to two GARs. We argue that this inconsistency may lead to confusion and incredibility among stakeholders.
