A bal kamrai globális myocardialis munka echokardiográfiás vizsgálata
Authors: Nemes Attila , Kormányos Árpád 
Published: November 2022

Összefoglaló. A bal kamra funkciójának megítélésére számos
echokardiográfiás paraméter alkalmas. Bár a bal kamrai ejekciós frakció és a
globális longitudinális strain széleskörűen alkalmazott paraméterek, használatuk
során limitáló tényezők változatlanul fennállnak. A globális myocardialis munka
noninvazív meghatározása ma már elérhető klinikai lehetőség, mely kombinálja a
speckle-tracking echokardiográfiás strainanalízist a brachialis artériában
mandzsettával systoléban mért vérnyomásértékkel. Az így számítható paraméterek
töltéstől független lehetőséget nyújtanak a bal kamra funkciójának jellemzésére.
A jelen összefoglaló mű célja ennek az új módszernek a rövid bemutatása a korai
eredmények ismertetése mellett, irodalmi adatok alapján. Orv Hetil. 2022;
163(13): 495–499.
Summary. Several echocardiographic parameters are suitable for the
evaluation of left ventricular function. Although left ventricular ejection
fraction and global longitudinal strain are widely used parameters, limitations
are still persisting. Non-invasive estimation of global myocardial work has
become a new clinical opportunity, which combines speckle-tracking
echocardiography-derived strain analysis with systolic blood pressure measured
by brachial cuff. Calculated parameters make a load-independent choice for
featuring left ventricular function. The present review aimed a short
demonstration of this methodology together with early results based on
literature. Orv Hetil. 2022; 163(13): 495–499.
Krónikus mucocutan candidiasis
Authors: Hon-Balla Bernadett , Erdős Melinda 
Published: November 2022

Összefoglaló. A krónikus mucocutan candidiasis genetikailag
heterogén betegségcsoport, amelyre a bőr, a körmök és a nyálkahártyák
Candida okozta tartós vagy visszatérő, nem invazív
fertőzése jellemző. A Candida-fertőzések iránti fokozott
fogékonyság oka a Th17-sejtes immunitás defektusa, amelynek hátterében különböző
gének mutációja állhat. A betegség izolált formájában, amelyet más néven
krónikus mucocutan candidiasis betegségnek is nevezünk, a mucocutan candidiasis
a betegség egyetlen vagy elsődleges tünete. Ezzel szemben a betegség ún.
szindrómás formáira a nem invazív Candida-fertőzések mellett
autoimmun betegség társulása is jellemző, amely a leggyakrabban az endokrin
rendszert érinti. A diagnózis megerősítésében fontos a genetikai vizsgálat,
amely az érintett családokban lehetőséget teremt praenatalis genetikai
vizsgálatok végzésére is. A szerzők bemutatják a krónikus mucocutan candidiasis
főbb típusait, klinikumát, és elemzik a diagnosztikus, illetve terápiás
lehetőségeket. A szerzők összefoglalják továbbá a betegség molekuláris genetikai
hátterét és a patomechanizmus jelenleg ismert folyamatait. Orv Hetil. 2022;
163(5): 171–180.
Summary. Chronic mucocutaneous candidiasis is a genetically
heterogeneous group of disorders, which are characterised by chronic or
recurrent non-invasive skin, nail and mucous membrane infections caused by
Candida. The increased susceptibility to
Candida infections is due to a Th17-cell mediated immune
defect with different gene mutations in the background. The isolated form of the
disorder, referred to as chronic mucocutaneous candidiasis, presents primarily
or only with mucocutaneous candidiasis. In contrast, the syndromic form of the
disorder is characterised, besides the non-invasive Candida
infections, by autoimmune disorders, which most commonly affect the endocrine
system. Genetic tests are important in confirming the diagnosis, which in
affected families would provide the opportunity for prenatal genetic testing.
The authors present the main types of chronic mucocutaneous candidiasis,
exploring the clinical aspects, diagnostic methods, and available therapies.
Furthermore, the authors conclude the molecular genetic background and the
currently known pathomechanism of the disorder. Orv Hetil 2022; 163(5):

SARS-CoV-2-fertőzés és annak megelőzése gyermekkori krónikus szisztémás autoimmun betegségekben
Authors: Constantin Tamás , Kulcsár Andrea , Krivácsy Péter , Mészner Zsófia , Ponyi Andrea , Tóth Attila , Ónozó Beáta , Szekanecz Zoltán 
Published: November 2022

Összefoglaló. A krónikus autoimmun betegségben szenvedőkben a súlyos
COVID–19 kialakulásának kockázata magasabb, a SARS-CoV-2-fertőzés pedig a
krónikus alapbetegség progressziójához, fellángolásához vezethet. A COVID–19
elkerülésének legbiztonságosabb, legköltséghatékonyabb módszere a vakcináció,
illetve az emellett alkalmazott higiénés szabályok betartása, a megfelelő maszk
viselése. A hiedelemmel ellentétben önmagában az autoimmun megbetegedés nem
jelent oltási ellenjavallatot, sőt a rizikóállapot miatt ezek a betegek az elsők
között oltandók. A COVID–19 elleni vakcina alkalmazásának egyetlen egyértelmű
kontraindikációja az anamnézisben szereplő súlyos allergiás reakció (anafilaxia)
a vakcina valamelyik alkotórészével szemben. A betegek olthatóságát többek
között befolyásolja az aktuális betegségaktivitás és az alkalmazott kezelés. Az
immunizáció idejét a legbiztonságosabban a gondozó orvos tervezheti meg. Az
autoimmun betegek immunizációja során észlelhető oltási reakciók és szövődmények
incidenciája megegyezik az egészséges populációban is tapasztalt előfordulási
gyakorisággal. Orv Hetil. 2022; 163(11): 414–423.
Summary. The risk of developing severe COVID–19 is higher in
patients with autoimmune diseases, and SARS-CoV-2 infection can lead to
progression and exacerbation of the underlying chronic disease. The safest and
most cost-effective way to avoid COVID–19 is to be vaccinated, to follow the
hygiene rules and to wear an appropriate mask. Contrary to belief, autoimmune
disease alone is not a contraindication to vaccination and, in fact, patients
should be among the first to be vaccinated because of the risk. The only clear
contraindication to the use of COVID–19 vaccine is a history of severe allergic
reaction (anaphylaxis) to any of the components of the vaccine. Indication of
vaccination migh be influenced by, among other things, the current disease
activity and the treatment applied. The timing of immunization can be the most
safely planned by the attending physician. The incidence of vaccination
reactions and complications during immunization in autoimmune patients is
similar to that seen in the healthy population. Orv Hetil. 2022; 163(11):

3D MRI bal pitvari hegtérkép által vezérelt anatómiai pulmonalis véna reizoláció
Authors: Fődi Eszter , van der Geest Rob J. , Tóth Attila , Simor Tamás 
Published: November 2022

Összefoglaló. Egy 58 éves hypertoniás nőbetegünk esetét ismertetjük,
aki erős szubjektív panaszokat okozó, gyakori, dokumentált pitvarfibrillációs
paroxizmusok miatt korábban két alkalommal pulmonalis véna izoláción esett át,
de palpitációérzései továbbra sem szűntek. Feltételezve a pulmonalis véna
rekonnekciót, a tartós ritmuszavar-mentesség elérését célozva a tervezett
harmadik pulmonalis véna izoláció előtt 3D MRI bal pitvari késői
kontraszthalmozásos képalkotást végeztünk. A felvételeken először a vékony bal
pitvarfal pontos endocardialis és epicardialis feszínét határoztuk meg
manuálisan, majd a fali kontraszthalmozás transmuralitasának megfelelő
színkódolást végeztünk. Az így nyert bal pitvari színkódolt felszíni
rekonstrukció három dimenzióban jelenítette meg a bal pitvarfalban lévő heges
területek elhelyezkedését. A felvételeket a tervezett harmadik beavatkozás során
beolvasva az elektroanatómiai rendszerbe, a megjelenített antralis
hegfolytonossági hiányok területében végeztünk szelektíven ablatiókat, és teljes
izolációt értünk el mind a négy vénában. A szövődménymentes beavatkozás után a
beteg tartósan panaszmentessé vált. Esetünk az első olyan hazai ismételt
pulmonalis véna izoláció, amelynek során a korábbi ablatiós hegek folytonossági
hiányait 3D MRI-hegtérkép alkalmazásával láthatóvá tettük, és az innovatív
módszerrel feldolgozott képek irányították az ablatiót, ily módon szüntetve meg
a hegfolytonossági hiányokat. Orv Hetil. 2022; 163(19): 767–772.
Summary. We present the case of a 58-year-old woman, suffering from
high blood pressure, who presented with documented frequently occurring
paroxysmal atrial fibrillation attacks. She underwent two prior pulmonary vein
isolations, but her palpitations did not cease. We aimed to achieve a long
period free of symptoms, and a 3D MRI late enhancement scar map of the left
atrium was obtained before the planned third pulmonary vein isolation procedure
to visualize the assumed pulmonary vein reconnection sites. First, the
endocardial and epicardial contours of the thin left atrial wall were manually
determined on the images, then color-coding was added based on the trasmurality
of contrast enhancement in the wall. The reconstructed 3D color-coded left
atrial surface revealed the localization of left atrial antral wall scars. These
images were integrated into the electroanatomical mapping system and ablation
was carried out selectively on the spots showing gaps in the antral scar.
Isolation was achieved in all four veins without any complications. The patient
has become symptom-free for years now. The reconstructed left atrial 3D MRI
images gained in an innovative process visualized the gaps in the previous
ablation lines and these images were integrated to guide the first gap-closure
redo pulmonary vein isolation procedure in Hungary. Orv Hetil. 2022; 163(19):

Korábban SARS-CoV-2-fertőzésen átesett betegek műtéti érzéstelenítése és perioperatív ellátása
Authors: Balla Boglárka , Fülesdi Béla , Végh Tamás 
Published: November 2022

Összefoglaló. A korábban SARS-CoV-2-vírusfertőzésen átesett
betegeknél különösen fontos az elektív műtét időpontjának megválasztása. Egy
több, mint százezer beteget felölelő tanulmány szerint átlagosan 7 hét szükséges
az elektív műtétre bocsátáshoz. Sürgős műtétek esetében a beteg általános
állapota és a műtéttől várt javulás alapján mérlegelendő a műtét időpontja. A
vitális indikációjú műtétek képezik a legnagyobb rizikót, hiszen ezen esetekben
igen csekély idő és lehetőség van a preoperatív betegelőkészítésre.
A SARS-CoV-2-vírusfertőzés nem minden esetben múlik el nyomtalanul.
Szövődményeként felléphetnek cardiopulmonalis, véralvadási, központi
idegrendszeri, mozgásszervi problémák, akut veseelégtelenség, ion- és
vércukorháztartás felborulása, valamint gastrointestinalis eltérések is, melyek
lehetnek rövid vagy hosszú távúak, illetve egyes esetekben maradandó károsodások
is.
A preoperatív kivizsgálási stratégiát, a műtéti érzéstelenítés módszerét
(általános vagy regionális), valamint az intraoperatív monitorozást ezen
szövődmények súlyosságának, valamint a műtét típusához megfelelően kell
megválasztani. A posztoperatív időszakban a SARS-CoV-2-vírusfertőzésen átesett
betegek körében gyakrabban lehet szükség emelt szintű monitorozásra vagy
intenzív osztályos megfigyelésre. Orv Hetil. 2022; 163(18): 695–701.
Summary. The timing of elective surgery is very important in
patients, who suffered SARS-CoV-2 virus infection. According to a study of more
than 100,000 patients, it takes approximately seven weeks to be safely admitted
to elective surgery. In the case of emergency surgeries, the date of the surgery
should be considered based on the patient’s general condition and the expected
improvement from the surgery. Surgery with a vital indication takes the greatest
risk, as there is very little time and opportunity for preoperative examination
in these cases.
SARS-CoV-2 virus infection does not go away without a trace. Complications may
include cardiopulmonary, coagulation, central nervous system, locomotor
problems, acute renal failure, ionic and diabetic disorders, and
gastrointestinal abnormalities, which may be short-term or long-term, and in
some cases permanent.
The preoperative examination strategy, the method of anesthesia (general or
regional) and the intraoperative monitoring should be chosen according to the
severity of these complications and the type of surgery. In the postoperative
period, patients suffered with SARS-CoV-2 virus infection may require more
frequent monitoring or intensive ward monitoring. Orv Hetil. 2022; 163(18):

Dynamic response of FG-CNTRC beams subjected to a moving mass
Authors: Ismail Esen , Tran Thom Thi , Nguyen Dinh Kien 
Published: November 2022

This article presents the forced vibration of composite beams reinforced by single-walled carbon nanotubes (SWCNTs) and subjected to a moving mass. Considering the distribution of carbon nanotubes such as uniform (UD-CNT), functionally graded Λ (FGΛ-CNT) and X (FGX-CNT), three different beams are studied. Based on a third-order shear deformation theory (TSDT), the motion equations of the beams are derived using Hamilton's principle. Including mass interaction forces, the motion equations are transformed into a finite element equation in which a two-node beam element with eight degrees of freedom is utilized. To improve the efficiency of the beam element, the transverse shear rotation is employed as an independent variable in the derivation of the beam element. The vibration characteristics, including the dynamic magnification factors and the time histories for mid-span deflections are computed by using the Newmark method. Numerical result reveal that the vibration of the beams is clearly influenced of the CNT reinforcement, and the dynamic magnification is significantly decreased by increasing the CNT volume fraction. It is also shown that the FGX-CNT beam is the best in dynamic resistance in terms of the lowest dynamic deflection and dynamic magnification factors. The effects of the total volume fraction and the moving load velocity on the dynamic behaviour of the functionally graded carbon nanotube reinforced composites (FG-CNTRC) beams are examined in detail and highlighted.

Published: November 2022

The calculation of safety parameters in nuclear reactors has an important influence on nuclear reactor control and safety. The infinite multiplication factor, reactivity coefficients, and power peaking factor parameters are the most important safety parameters for determining reactor status. The aim of the present study is to analyze the behavior of the nuclear safety parameters for the VVER-1200 core in a normal state of reactor operation. A lattice cell fuel model of the VVER-1200 reactor core was performed using WIMSD-5B. The cross-section library data based on the ENDF/B-VIII.0 was used. The investigated parameters were the value of infinite multiplication factor with different pitch, temperature, enrichment, and boron concentration. The calculation also investigated the reactivity coefficient parameters. The verification of WIMS model VVER-1200 was performed by comparing the results of the WIMSD-5B code with VVER-1200 data in the SAR document, and it was implied that they are in good agreement. The calculated values of reactivity coefficients illustrated a safe behavior.

Authors: Kanwal Naumana , Iqbal Muhammad Javed , Mushtaq Mariam 
Published: November 2022

Syntactic choices and complexity reduction make translation communicative for the readers. This paper underscores the syntactic choices as well as complexity reduction in Urdu translation of Punjab laws in English. The study focuses on legal communication in a minimalistic perspective. It draws upon the theory of minimalism proposed by Chomsky (1993), along with the three-stage model by Nida and Taber (1969). Data is analyzed by employing Burton’s (2021) clausal analysis. The legal data used for the research comprises Punjab laws in English and their Urdu translation. The findings reveal minimalism as a useful strategy in the translation process for reducing structure complexity and making the translation understandable to laypeople. The study is beneficial to English-Urdu translators since it instructs them on how to make their translations communicative, especially when dealing with legal texts. It is also useful for academics in the field of Translation Studies who are working on minimalist views.Keywords: minimalism, complexity reduction, legal translation, syntactic choices, communication

High operational cost is a perennial problem in banking sector in Rwanda. The purpose of this study was to examine the effect of cost management strategies on operational efficiency of commercial banks in Rwanda with special reference to Bank of Kigali. The cost management strategies that formed the specific objectives included recruitment and training, technology and business process re-engineering. The target population was 140 managers of Bank of Kigali. A sample size of 103 calculated from Yamane’s formula was utilized. The study adopted descriptive research design. The study data constituted both primary and secondary data. Primary data was collected using questionnaires which were distributed to the managers. Secondary data was collected from published financial reports of BK. The study adopted purposive, stratified and random sampling techniques. The data was cleaned and entered into SPSS version 22 for processing. Presentation of data was aided by tables and graphics Descriptive analysis involved computing frequencies and percentages. Inferential analysis involved computing Pearson correlation coefficient and regression coefficients. Descriptive findings indicated that majority of respondents were in agreement that recruitment and training, technology and business process re-engineering indeed affect operational efficiency. Correlation analysis findings indicated that Pearson’s correlation coefficient for recruitment and training, technology and business process re-engineering were 0.69, 0.75 and 0.56 which are all positive and significant an indication of a positive association between cost management strategies and operational efficiency. Regression analysis also reported R Squared value of 0.692 an indication that cost management strategies account for 69.2% of operational efficiency variations. Moreover, beta coefficients for recruitment and training, technology and business process re-engineering were found to be positive and significant indicating that there is a positive significant effect of cost management strategies on operational efficiency. This study is of importance to the commercial banks’ management team, BNR and academicians or rather future researchers who wish to explore more in the financial sector.

Published: November 2022

En la actualidad, las cadenas de suministro buscan establecer estrategias para la recuperación y reincorporación de los productos que cumplen su vida útil, no obstante en estas operaciones de logística inversa se presentan eventos que pueden generar no solamente pérdidas financieras para la empresa, sino también efectos nocivos sobre el medio ambiente y la comunidad. En este documento se realiza un proceso de identificación, priorización y control para los riesgos operacionales más representativos en el proceso de logística inversa del aceite vehicular usado debido al alto volumen de este residuo que se genera dentro del país y cuya mala gestión de las actividades de recuperación puede generar problemas ambientales, económicos y sociales. La metodología utilizada para el proceso de gestión de riesgo implica el uso de la herramienta multicriterio QFD Fuzzy, para evaluar los eventos operacionales más comunes dentro del proceso usando la valoración de expertos en el sector, y posteriormente se diseña una serie de estrategias de mitigación a través del uso del diagrama Ishikawa. Entre los resultados más relevantes encontrados en el estudio se tiene el hecho de que los riesgos más relevantes en la logística inversa del aceite vehicular usado son el inadecuado proceso de almacenamiento, la ausencia de un vehículo adecuado para el transporte y la baja calidad del residuo. La investigación realizada establece un marco de referencia para el proceso de gestión del riesgo en compañías que se dediquen al aprovechamiento y reutilización de productos en una cadena de suministro de ciclo cerrado.

Published: November 2022

Case:
A 7-year-old girl presented with a recurrent hammertoe deformity causing pain with shoe wearing after a prior corrective surgery. Surgical revision required a unique approach that included a staged corrective osteotomy of the proximal phalanx because of hypoperfusion management and the application of a rotational skin flap previously described for camptodactyly correction in the hand to avoid harvesting a skin graft.

Conclusion:
Revision surgery for recurrent pediatric hammertoe deformity requires a heightened awareness of the risk for toe hypoperfusion and subsequent wound closure challenges.
A novel method for handling missing data in health care real-world study: Optimal Intact Subset Method
Authors: Jingxian Wu , Huan Chang , Rongsheng Tong , Xingwei Wu 
Published: November 2022

Abstract
Handling missing data is indispensable in health-care real-world data processing. Imputing method may introduce error and multicollinearity. Therefore, we explored (Optimal Intact Subset Method, OIS.Method) to avoid the issues. By exploring an optimal deleting way of columns and rows with missing data, a subset retaining most information of original datasets was determined. Traditionally, we can traverse all deleting ways. But the computational cost is too high to use in large datasets. OIS.Method used an indicator to determine the optimal deleting order which can ascertain the optimal deleting way and simplify computing. In order to validate the effectiveness of OIS.Method, we compared OIS.Method with five other missing data handling methods in simulated real-world classification datasets. Additionally, we validated OIS.Method in two real-world classification tasks. In simulated datasets, the performance of OIS.Method was best(highest AUC was 1). In real-world datasets, OIS.Method could acquire better classification performance. Take AUC for an example: OIS.Method VS Simple Impute VS Random Forest VS Modified Random Forest, 0.8179±0.0005 VS 0.8116±0.0002 VS 0.8087±0.0009 VS 0.8093±0.0014 in task1, and 0.7028±0.0126 VS 0.6963±0.0231 VS 0.6957±0.0247 VS 0.6699±0.0249 in task2. The calculation of OIS.Method is smaller, and it is well-suited for large real-world datasets.
