Among all scientific traditions alive, medical publishing has a good chance to be the oldest. The first fully peer reviewed academic journal, “Medical Essays and Observations” was launched in 1731 by the Royal Society in Edinburgh. Since then, hundreds of medical journals have been published worldwide. Medical publication in Hungary started in 1857 when the famous physician, Markusovszky founded “Orvosi Hetilap”, which has been published since then every week (with short breaks during the world wars). It is now a most prestigious piece in AKJournals’ portfolio, listed in Journal Citation Reports, with a remarkable impact factor.

The primary function of medical articles is the validation of cutting-edge theoretical and clinical research, by providing reference and relevant forums. New drugs and medical practices can only enter the mainstream practise if their randomised trials had passed under the critical lens of prestigious peer reviewed journals. Technical reports help practitioners to improve their arsenal. Case reports confirm theories and provide tools for investigating or disclosing possible malpractice. Review articles serve educational purposes. Some more popular articles may play a role in educating the interested audience.

Types of medical articles

The papers published in medical journals can be classified in the following main categories

  • Research articles report about novel research results, of both theoretical and (direct or indirect) practical relevance.
  • Review articles survey specific topics by summarising and analysing all information available in the medical literature. Reviews are kind of combining results from different studies on the same topic. They can be useful for specialists in the field, may help them to prevent, diagnose, or treat a particular disease.
  • Case reports and case series reports about a concrete story of a concrete patient. They can be interesting because of their uniqueness, not matching any known diagnosis or describing unexpected symptoms. The report should describe each of the diagnosis, treatment, the patient’s response to it and the follow-up history. Case series are related reports about similarly treated patients.
  • Editorials are typically not peer reviewed shorter communications from senior members of the Editorial Board or from invited renown scholars. They discuss questions of relevance for the scientific community at the moment (say, about public health, or more generally, the health system).
  • Letters to the editor are articles of the interactive type, a form for readers to contact the medical journal. They can express comments, questions, or criticisms regarding some articles published in that journal. They provide a sophisticated forum for medical communities.

Összefoglaló. Bevezetés: A koronavírus elleni védőoltással kapcsolatos vélekedések igen aktuális, társadalmi szempontból fontos területét adják az egészségmagatartással foglalkozó kutatásoknak. Célkitűzés: Vizsgálatunk a védőoltásról különbözőképpen vélekedő (oltást elutasító, oltást választó, oltáson nem gondolkodó, valamint bizonytalan) csoportok elemzését tűzte ki célul az oltás előnyeinek és hátrányainak, valamint az információforrások használatának tekintetében. Módszer: A mintát „A koronavírus-járvány okozta lelki tényezők utánkövetéses vizsgálatának” 2020 decemberében felvett adatai adják; a vizsgálat során 1009 fő válaszait egyszempontos varianciaanalízissel elemeztük. Eredmények: Eredményeink azt mutatják, hogy a budapestiek és a Közép-Magyarországon élők, az idősebbek, a férfiak, a magasabb iskolai végzettségűek, valamint a házasok választják nagyobb eséllyel a védőoltást. Az oltásról különbözőképpen vélekedő csoportokat az oltás előnyei jobban elkülönítik egymástól, mint az oltás hátrányai. Az előnyök közül a csoportokat főképp a társas, társadalmi érdekekre fókuszáló tételek differenciálják, melyek a járvány megfékezéséről, a fertőzés átadásáról szólnak. A használt információforrásokat elemezve pedig elmondható, hogy mind a négy csoport jobban támaszkodik a személyes (család, barátok) és az orvosi, egészségügyből érkező információkra, mint a médiából érkező hírekre. Következtetés: Az oltási csoportok véleménye az oltás pozitív hozadékait, különösképp társadalmi hasznosságát illetően tér el, mely vélemények a leginkább a személyes kapcsolatokon, így az egészségügyi dolgozók álláspontján keresztül formálódnak. Tehát az egészségügyben dolgozóknak kiemelkedő szerepük van a hozzájuk tanácsért fordulók differenciált megértésében, szakértői tájékoztatásában és megfelelő tanácsokkal való ellátásában.

Summary. Introduction: Beliefs regarding coronavirus vaccination provide very actual and socially important area in mental health research. Objective: The aim of our study was to differentiate the opinions related to coronavirus vaccination (acceptance, refusal, ignorance, hesitation). We analyzed advantages and disadvantages of vaccination, and the different channels in getting information about the vaccine. Method: Our study is part of the “Longitudinal examination of mental factors caused by the coronavirus epidemic” research project, wave of December 2020. We analyzed the responses of 1009 people by one-way analysis of variance tests. Results: Our results show that elder people, males, and those who have higher education are more likely to accept the vaccine. In addition, those who live in Budapest and Cental Hungary are more likely to choose vaccination against the coronavirus than those living in other areas. The groups with different opinions on vaccination are better discriminated by benefit-related than risk-related opinions. Those benefit-related items showed the largest variance between groups, which focused on social usefulness on curbing the epidemics, preventing the spread of the infection. Analyzing the sources of information, we found that all groups rely more on personal (family, friends) and medical health information than on news from the media. Conclusion: The opinions of the vaccination groups differ mostly regarding the positive benefits of vaccination, especially the social usefulness. Opinions are mostly formed through personal relationships including relations with healthcare workers. Healthcare professionals therefore have a key role in providing a differentiated understanding of those seeking advice, providing expert information and appropriate advice.

SARS-CoV-2-fertőzés és COVID–19 Gaucher-kóros betegekben: a védőoltás javallata

SARS-CoV-2 infection and COVID‒19 in Gaucher disease: indications for vaccination

Orvosi Hetilap
Author: László Maródi

Összefoglaló. Az új típusú koronavírus (SARS-CoV-2) okozta pandémia kezdetén a szakmai közvélemény általános vélekedése a Gaucher-kóros betegek fokozott érzékenységét vetítette elő, magas morbiditási és mortalitási mutatókkal. Meglepő módon azonban az eddigi, nagyszámú betegen, az Egyesült Államokban, Európában és Izraelben végzett klinikai tanulmányok azt mutatják, hogy ezen súlyos anyagcsere-betegségben sem a fertőzésnek kitett betegek morbiditási adatait, sem a ritkán kialakult fertőzések súlyosságát tekintve nem áll fenn csökkent immunvédekezés a SARS-CoV-2-vel szemben. Ezen immunológiai és infektológiai paradoxon lehetséges magyarázata, hogy a betegek makrofágjaiban és más sejtjeiben felhalmozódó glükocerebrozid gyulladásos állapotot tart fenn, amely hátrányos a kórokozó vírus intracelluláris túlélése szempontjából. A közleményben összefoglaljuk a témakörben eddig megjelent tanulmányok adatait, az általános prevencióval és a vakcinációval kapcsolatos ajánlásokat, és kitérünk az 1-es típusú interferonok (IFNα és IFNω) közelmúltban megismert szerepére a SARS-CoV-2-vel szembeni immunitásban. Orv Hetil. 2021; 162(24): 938–942.

Summary. At the start of the pandemic caused by the novel coronavirus (SARS-CoV-2), the Gaucher disease community anticipated that infection with this emerging viral pathogen would be associated with high morbidity and mortality in individuals with this chronic metabolic disorder. Surprisingly, however, preliminary studies suggest that Gaucher disease does not confer a higher risk of severe, life-threatening effects of SARS-CoV-2 infection, and no severe cases have been reported in large cohorts of patients from the United States, Europe and Israel. It is thought that the accumulation of glucocerebroside in the cells of Gaucher patients may promote immune tolerance rather than inflammation on exposure to SARS-CoV-2. We review here the current concepts of Gaucher disease and SARS-CoV-2 infection, focusing particularly on general prevention and vaccination. We also discuss the susceptibility to COVID-19 of patients with inborn errors of type 1 interferon (IFNα and IFNω) immunity. Orv Hetil. 2021; 162(24): 938–942.

Authors: Tibor Takács, Gábor Mihalovits, Rita Váradi, András Nagy, Endre Nagy, and Zsolt Palásthy

Összefoglaló. Bevezetés: Az endovascularis intervenciókat kezdetben radiológusok alkalmazták, manapság, megfelelő képzést követően, jó eredménnyel végeznek ilyen beavatkozásokat érsebészek is. Ezt a világszerte uralkodóvá váló szemléletet kívántuk meghonosítani a Szegedi Tudományegyetemen, melynek bevezetése nélkül előrevetíthető az érsebészet működésének átalakulása az érrekonstrukciós beavatkozások csökkenésével. Célkitűzés: Egyetemünkön radiológus- és érsebész-munkacsoport végez perifériás érintervenciókat. Célunk a két intézet alsó végtagi endovascularis tevékenységének összehasonlítása volt. Módszer: Vizsgálatunkba a Szegedi Tudományegyetemen 2012. 01. 01. és 2019. 12. 31. között alsó végtagi endovascularis beavatkozásokon átesett betegeket válogattuk be. A betegeket a rizikófaktoraik, a kezelt anatómiai régiók, a hospitalizációs idő és a szövődmények tekintetében hasonlítottuk össze. Egyéves utánkövetés során vizsgáltuk a ’redo’ műtétek , az amputációk és a halálozások gyakoriságát. Eredmények: A beavatkozásokat 653 esetben radiológus, 573 esetben érsebész végezte. Az érműtőben infrainguinalis (63,2%), a radiológián suprainguinalis érintervenciók (68,6%) történtek nagyobb arányban. A percutan végzett beavatkozásokat vizsgálva a hospitalizációs időben (2,5 ± 4,4 nap vs. 2,4 ± 2,5 nap, p = 0,78), valamint a minimálisan invazív módon végzett beavatkozások utáni szövődmények gyakoriságában (30/653 – 4,6% és 11/257 – 4,3%, p = 0,837) nem volt különbség a két betegcsoport között. ’Redo’ műtétek (73/485 – 15,1% és 33/562 – 5,9%, p<0,001) és amputációk (31/485 – 6,4% és 12/562 – 2,1%, p<0,001) gyakrabban fordultak elő az érműtőben kezelt betegek körében, ebben a csoportban azonban a kritikus végtagischaemia előfordulása is gyakoribb volt (45,4% és 38,6%, p = 0,016). A mortalitásban nem volt szignifikáns különbség (5,8% és 3,9%, p = 0,16). Következtetés: A szoliter érelváltozások kezelését mindkét intézet hasonló hatásfokkal végezte. A több anatómiai régiót érintő betegség miatt érműtőben végzett beavatkozások utáni szövődmények előfordulása kissé magasabbnak bizonyult. Orv Hetil. 2021; 162(24): 943–951.

Summary. Introduction: Endovascular interventions were initially performed by radiologists. Nowadays properly trained vascular surgeons also effectively perform these interventions. We wished to apply this widespread practice at our university because without this advancement the number of reconstructive surgeries was expected to decrease significantly. Objective: Both radiologists and vascular surgeons perform endovascular interventions at our university. We compared the outcomes of lower extremity endovascular interventions between the two institutes. Method: We included patients who underwent lower extremity endovascular interventions between 01. 01. 2012 and 31. 12. 2019. We compared the risk factors, treated anatomical regions, hospitalization time and complication rate. During the one-year follow-up, we examined the occurrence of redo surgeries, amputations and mortality. Results: 653 interventions were performed by radiologists and 573 by vascular surgeons. Vascular surgeons carried out more interventions in the infrainguinal region (63.2%), while radiologists in the suprainguinal region (68.6%). The hospitalization time after percutaneous interventions (2.5 ± 4.4 days vs. 2.4 ± 2.5 days, p = 0.78), and the rate of complications after minimally invasive interventions did not show significant difference (30/653 – 4.6% vs. 11/257 – 4.3%, p = 0.837). Redo surgeries (73/485 – 15.1% vs. 33/562 – 5.9%, p<0.001) and amputations (31/485 – 6.4% vs. 12/562 – 2.1%, p<0.001) occurred more frequently in the surgical group. However, the incidence of chronic limb ischaemia was also higher (45.4% vs. 38.6%, p = 0.016). There was no significant difference in the mortality (5.8% vs. 3.9%, p = 0.16). Conclusion: Both institutes had similar efficacy in performing peripheral interventions on solitary vascular lesions. Complications occurred more frequently in the surgical group, but the majority of these patients had extended atherosclerotic diseases. Orv Hetil. 2021; 162(24): 943–951.

Összefoglaló. Bevezetés: A gliomák, ezen belül a glioblastoma kezelése továbbra is megoldatlan onkológiai problémát jelent. A szekunder szimptómás epilepsziabetegség megjelenése pozitív prognosztikai faktornak tekinthető a korai diagnosztizálás és az antiepileptikumok potenciális tumorellenes hatásának köszönhetően. A valproát túlélést hosszabbító hatása már több mint 20 éve az alap- és klinikai kutatások tárgyát képezi. Napjainkban ismert citotoxikus, proapoptotikus, antiangiogenetikus és hiszton-deacetiláz-gátló hatásmechanizmusa. Célkitűzés: Kutatásunk célja a valproát túlélést hosszabbító hatásának vizsgálata egy hazai gliomás betegcsoportban. Módszer: Egycentrumos, retrospektív klinikai vizsgálatot végeztünk. A vizsgálatba 122 felnőtt beteget vontunk be, akiknél 2000 januárja és 2018 januárja között supratentorialis glioma miatt műtét történt, és rohamtevékenység miatt antiepileptikumot (valproát, levetiracetám, karbamazepin) szedtek. Egyúttal gyógyszert nem szedő kontrollcsoportot is kialakítottunk. A populációt vizsgálati és kontrollcsoportokra osztottuk 28 : 52 arányban. Leíró statisztikai, Kaplan–Meier- és log-rank analízist végeztünk. Eredmények: A vizsgált szövettani kategóriák túlélési analízise az irodalmi adatokkal megegyező értékeket mutatott. A progressziómentes (PFS: p = 0,031) és a teljes (OS: p = 0,027) túlélés tekintetében is szignifikáns eltérés mutatkozott a különböző antiepileptikumot szedő betegcsoportok között, amely még kifejezettebbé vált a valproátot és az egyéb antiepileptikumot szedő betegek túlélési idejének összehasonlítása során (PFS: p = 0,006; OS: p = 0,015). Következtetés: Vizsgálatunkban a valproát betegeink PFS- és OS-idejének meghosszabbodását eredményezte. Az irodalmi adatok és kutatásunk alapján megfontolandónak tartjuk a valproát első vonalban történő alkalmazását onkoterápiában részesülő, epilepsziás, agyi gliomás betegekben. Orv Hetil. 2021; 162(24): 960–967.

Summary. Introduction: Gliomas still prove to be a serious oncological problem. The presence of epilepsy may present a favorable prognosis due to early diagnosis and the potential antitumor effects of antiepileptic drugs. The survival prolongation effect of valproate has been studied for more than 20 years, nowadays its proapoptotic, anti-angiogenetic, cytotoxic and histone deacetylase inhibitory effects are well known. Objective: Our goal was to investigate the survival-enhancing effects of valproate in a Hungarian patient cohort of primary brain tumors. Method: A single-center based retrospective clinical trial was designed. In our study, we included 122 patients harboring supratentorial glioma who underwent surgery and experienced seizures between 2000 January and 2018 January. The patients were grouped by the antiepileptic therapies and survival analysis was performed. Results: The Kaplan–Meier curves of the histological categories showed the survival values consistent with the data of the literature. The progression-free (PFS: p = 0.031) and the overall (OS: p = 0.027) survival of the antiepileptic drug categories were significantly different. It was performed by comparing the valproate group and the population formed by the other groups which also showed a significant increase in the survival values (PFS: p = 0.006; OS: p = 0.015). Conclusion: Our results show that valproate increases the PFS and OS period of glioma patients in comparison to other antiepileptic drugs. Our data suggest that the use of valproic acid should be considered as a first-line antiepileptic agent in certain well-selected epileptic patients with glioma as a supplement to the oncotherapy.

Abstract

It has been proven in a few early studies that radiomic analysis offers a promising opportunity to detect or differentiate between organ lesions based on their unique texture parameters. Recently, the utilization of CT texture analysis (CTTA) has been receiving significant attention, especially for response evaluation and prognostication of different oncological diagnoses. In this review article, we discuss the unique ability of radiomics and its subfield CTTA to diagnose lesions in the pancreas and kidney. We review studies in which CTTA was used for the classification of histology grades in pancreas and kidney tumors. We also review the role of radiogenomics in the prediction of the molecular and genetic subtypes of pancreatic tumors. Furthermore, we provide a short report on recent advancements of radiomic analysis in predicting prognosis and survival of patients with pancreatic and renal cancers.

Abstract

Widespread introduction of HIV integrase inhibitors into clinical care may result in appearance of drug resistance mutations affecting treatment outcome. The aim of our study was to monitor the resistance patterns of integrase inhibitors beside protease and reverse transcriptase inhibitors in newly diagnosed therapy-naive HIV-positive patients in Hungary between 2017 and 2019.

Genotype-based resistance testing of HIV integrase, protease and reverse transcriptase was performed by amplification and Sanger population sequencing from plasma samples. Drug resistance mutations were identified by the algorithm of Stanford HIV Drug Resistance Database.

Potentially transmitted, non-polymorphic integrase major mutation was detected in 1 out of 249 samples, while accessory mutations were observed in further 31 patients (12.4%). The overall prevalence of transmitted drug resistance (TDR) mutations related to protease and reverse transcriptase inhibitors was 5.8% (10/173) between the end of 2017 and 2019. Nucleoside reverse transcriptase inhibitor associated resistance mutations were the most frequent indicators of TDR (6/173; 3.5%), followed by resistance mutations associated with protease (3/173; 1.7%) and non-nucleoside reverse transcriptase inhibitors (2/173, 1.2%).

The first detection of integrase major mutation and the changing patterns of other resistance mutations in Hungarian untreated HIV-positive population indicate the necessity of continuous molecular surveillance of Hungarian HIV epidemic.

ABSTRACT

Background and Aim

Right ventricular (RV) ejection fraction (EF) assessed by 3D echocardiography is a powerful measure to detect RV dysfunction. However, its prognostic value in routine clinical practice has been scarcely explored. Accordingly, we aimed at investigating whether RVEF is associated with 2-year all-cause mortality in patients who underwent diverse cardiovascular procedures and to test whether RVEF can overcome conventional echocardiographic parameters in terms of outcome prediction.

Patients and Methods

One hundred and seventy-four patients were retrospectively identified who underwent clinically indicated transthoracic echocardiography comprising 3D acquisitions. The patient population consisted of heart failure with reduced ejection fraction patients (44%), heart transplanted patients (16%), and severe valvular heart disease patients (39%). Beyond conventional echocardiographic measurements, RVEF was quantified by 3D echocardiography. The primary endpoint of our study was all-cause mortality at two years.

Results

Twenty-four patients (14%) met the primary endpoint. Patients with adverse outcomes had significantly lower RVEF (alive vs. dead; 48±9 vs. 42±9%, p<0.01). However, tricuspid annular plane systolic excursion (21±7 vs. 18±4mm), and RV systolic pressure (36±15 vs. 39±15mmHg) were similar. By Cox analysis, RVEF was found to be associated with adverse outcomes (HR [95% CI]: 0.945 [0.908 – 0.984], p<0.01). By receiver-operator characteristic analysis, RVEF exhibited the highest AUC value compared with the other RV functional measures (0.679; 95% CI: 0.566 – 0.791).

Conclusions

Conventional echocardiographic measurements may be inadequate to support a granular risk stratification in patients who underwent different cardiac procedures. RVEF may be a robust clinical parameter, which is significantly associated with adverse outcomes

Abstract

In this study, faecal samples of four American Staffordshire terrier dogs (used for illegal fighting) were analysed by DNA extraction, molecular-phylogenetic and parasitological methods, in order to examine the occurrence of protozoan, apicomplexan parasites. In one sample, the DNA of Sarcocystis morae was shown to be present. This species was identified based on 100% identity with already reported sequences of S. morae from cervids in Lithuania and Spain. The result was also confirmed by phylogenetic analysis. The sporocysts of the canine S. morae isolate measured 14.95 × 9.75 μm on average. This is the first molecular evidence in support of the final host role of domestic dogs in the life cycle of S. morae. The most likely source of the infection was raw meat given to the examined dog to increase its physical achievement. In conclusion, under similar circumstances dogs may participate in the life cycle of S. morae in a ‘natural way’, shedding sporocysts/oocysts when used for hunting or taken to walks in forested areas.

Abstract

Mast cell tumour (MCT) is the most frequent skin neoplasm in dogs. These tumours are characterised by variable behaviour and clinical presentation that make prognosis an important and challenging task in the veterinary practice. Galectin-3 (Gal-3) is known to influence several biological processes that are important in the cancer context and has been described as a prognostic marker for several human cancers. The aim of the present work was to characterise Gal-3 immunolabelling in canine cutaneous MCTs and to investigate its value as a prognostic marker for the disease. Thirty-four random cases of canine cutaneous MCT that were surgically treated with wide margins were included in this study. Gal-3 expression was evaluated using immunohistochemistry and the results were compared with the expression of apoptosis-related proteins, Ki67 index, histopathological grades, mortality due to the disease and post-surgical survival. The majority of the MCTs (65.8%) were positive for Gal-3. Gal-3 immunolabelling was variable among the samples (2.7%–86.8% of the neoplastic cells). The protein was located in the cytoplasm or in the cytoplasm and the nucleus. Gal-3 positivity was correlated with BCL2 expression (P < 0.001; r = 0.604), but not with Ki67 and BAX. No significant differences were detected between histological grades or in the survival analysis. Gal-3 expression correlates with BCL2 expression in MCTs. Although an efficient marker for several human neoplasms, the results presented herein suggest that Gal-3 immunolabelling is not an independent prognostic indicator for this disease.

Abstract

Q fever is a disease of high zoonotic potential, but interest in its causative agent is rather low although it causes some public health problems in Hungary. The prevalence of Q fever is highly variable by country. The main reservoirs of the disease are the same domestic ruminant species everywhere, but the epidemiological profile depends on the features of the specific reservoir. The aim of this large-scale study was to demonstrate the importance of Q fever in different species as a possible source for human infection in most regions of Hungary. A total of 851 serum samples from 44 dairy farms, 16 sheep flocks, 4 goat farms and 3 zoos located in different parts of Hungary were tested. The presence of antibodies to Coxiella burnetii was surveyed in dairy cattle (n = 547), goats (n = 71), sheep (n = 200) and zoo animals (n = 33). The animal species tested in Hungary showed different seroprevalence values of C. burnetii infection. Seropositivity by the enzyme-linked immunosorbent assay was found in 258 out of 547 (47.2%) cows and in 69 out of 271 (25.5%) small ruminants, among them in 47 out of 200 (23.5%) sheep and in 22 out of 71 (31.0%) goats. Antibodies to C. burnetii were not detected in zoo animals. Seropositivity was demonstrated in 44 out of 44 (100%) dairy cattle farms, with at least one serum sample found to be positive on each farm. The seropositivity rate of small ruminant farms was 55.0% (11 positive out of 20 tested), with 9 out of 16 (56.3%) sheep flocks and 2 out of 4 (50.0%) goat herds showing seropositivity.
