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  • Editorials are typically not peer reviewed shorter communications from senior members of the Editorial Board or from invited renown scholars.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. A mikroszkóp felfedezése óta tudjuk, hogy az egymással szoros közelségben élő egyedeknek nem csupán a látható élőhelyük közös, hanem szemmel nem érzékelhető mikroorganizmusokat is megosztanak egymással, melyek bizonyos fokban adaptálódtak gazdáikhoz. Az emberek életterének bővülésével és ezzel párhuzamosan az állatok élőhelyének csökkenésével azonban új állatfajok kerülhetnek veszélyes közelségbe, ami következményes mikrobaátadással és az új gazdában a mikroba eltérő viselkedésével járhat. Feltételezhetően ez a jelenség vezetett a súlyos akut légzőszervi szindróma koronavírus-2 (SARS-CoV-2) kialakulásához, mely 2019-ben jelent meg először emberekben, és néhány hónap leforgása alatt milliókat fertőzött meg az egész világon. A pandémia leküzdéséhez és az újabb járványok megelőzéséhez minden lehetséges eszközt fel kell használni, ami együttműködést kíván a humánorvoslás és az állatgyógyászat, valamint az ökológiai, evolúciós és környezeti tudományok szakemberei között a globális „Egy Egészség” keretében. A közös célok érdekében történő összefogás jegyében a jelen tanulmány állatorvos és humánorvos szerzőpárosa összefoglalja azon ismereteket, amelyek a SARS-CoV-2 vonatkozásában mindkét szakma számára érdemlegesek lehetnek. Bemutatásra kerül a vírus eredete, természetes és mesterséges előfordulása különböző állatfajokban, valamint az állati koronavírusokkal kapcsolatos azon tapasztalatok, amelyek hozzájárulhatnak a SARS-CoV-2 működésének megértéséhez és az ellene való védekezés tökéletesítéséhez.

Summary. Introduction: Since the discovery of the microscope, we have known that individuals living in close proximity to each other share not only their visible habitat, but also invisible microorganisms that have adapted to some degree to their hosts. However, as human habitat expands and, in parallel, animal territory declines, new animal species can come into dangerous proximity, which may result in consequential transmission of microbes and different microbial behaviour in the new host. Presumably, this phenomenon led to the development of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which first appeared in humans in 2019 and infected millions over the course of a few months worldwide. All possible means must be used to combat the pandemic and prevent further epidemics, which will require cooperation between professionals in human medicine and veterinary medicine as well as in the ecological, evolutionary and environmental sciences, within the framework of the global “One Health”. In a spirit of working together for common goals, the authors of this study, a veterinarian and a human physician, summarize the knowledge that may be relevant to both professions for SARS-CoV-2. The origin of the virus, its natural and artificial occurrence in different animal species, and experiences with animal coronaviruses that may contribute to the understanding of the functioning of SARS-CoV-2 and the development of protection against it are presented.

Abstract

The present study evaluated the carbapenem resistance mechanisms of Klebsiella pneumoniae strains isolated in two Greek tertiary teaching hospitals and their susceptibility to currently used and novel antimicrobial agents.

Forty-seven carbapenem resistant K. pneumoniae strains were collected in G. Papanikolaou and Ippokrateio hospital of Thessaloniki between 2016 and 2018. Strain identification and antimicrobial susceptibility was conducted by Vitek 2 system (Biomérieux France). Susceptibility against new antimicrobial agents was examined by disk diffusion method. Polymerase chain reaction (PCR) was used to detect bla KPC, bla VIM, bla NDM and bla OXA-48 genes.

The meropenem–EDTA and meropenem–boronic acid synergy test performed on the 24 K. pneumoniae strains demonstrated that 8 (33.3%) yielded positive for metallo-beta-lactamases (MBL) and 16 (66.6%) for K. pneumonia carbapenemases (KPC) production. Colistin demonstrated the highest in vitro activity (87.7%) among the 47 K. pneumoniae strains followed by gentamicin (76.5%) and tigecycline (51%). Among new antibiotics ceftazidime/avibactam showed the highest sensitivity (76.6%) in all strains followed by eravacycline (66.6%). The bla KPC gene was present in 30 strains (63.8%), the bla NDM in 11 (23.4%) and the bla VIM in 6 (12.8%). The bla OXA-48 gene was not detected.

Well established antimicrobial agents such as colistin, gentamicin and tigecycline and novel antibiotics like ceftazidime/avibactam and eravacycline can be reliable options for the treatment of invasive infections caused by carbapenem-resistant K. pneumoniae.

Abstract

The increasingly wide use of next-generation sequencing technologies has revolutionised our knowledge of microbial environments associated with human skin, gastrointestinal tract and blood. The collective set of microorganisms influences metabolic processes, affects immune responses, and so directly or indirectly modulates disease. Rosacea is a skin condition of abnormal inflammation and vascular dysfunction, and its progression is affected by Demodex mites on the skin surface. When looking into the effects influencing development of rosacea, it is not only the skin microbiome change that needs to be considered. Changes in the intestinal microbiome and their circulating metabolites, as well as changes in the blood microbiome also affect the progression of rosacea. Recent research has confirmed the increased presence of bacterial genera like Acidaminococcus and Megasphera in the intestinal microbiome and Rheinheimera and Sphingobium in the blood microbiome of rosacea patients. In this review we discuss our current knowledge of the interactions between the immune system and the skin, gut and blood microbiome, with particular attention to rosacea diagnostic opportunities.

Abstract

In this study investigation of plasmid-mediated mcr 1-5 resistance genes was performed among multidrug-resistant (MDR) colistin sensitive and resistant Klebsiella pneumoniae and Escherichia coli strains isolated in our laboratory. We aimed to evaluate automated system (Vitek-2), broth microdilution (BMD) reference method and chromogenic media performance. Totally 94 MDR K. pneumoniae and six E. coli isolates were included in the study. CHROMID® Colistin R agar (COLR) (bioMerieux, France) was used to determine the colistin resistance by chromogenic method. Standard PCR amplification was performed using specific primers to screen the plasmid-mediated mcr 1-5 genes. Sixty-one isolates were resistant to colistin and 39 were susceptible with reference BMD. The essential and categorical agreement of Vitek-2 was determined as 100 and 99%. The sensitivity of COLR medium was 100%, the specificity was 97.5%. In our study mcr-1 was detected in eight isolates, while other mcr genes were not detected. Due to the high sensitivity and specificity of the COLR medium, it can be used in routine diagnostics for the detection of colistin resistance. In our study we detected 8% prevalence of mcr-1 among MDR strains however, two mcr-1 positive isolates were found sensitive to colistin by BMD.

Abstract

We aimed to assess the prevalence of pathogenic bacteria and resistance genes in rectal samples collected among homeless persons in Marseille, France. In February 2014 we enrolled 114 sheltered homeless adults who completed questionnaires and had rectal samples collected. Eight types of enteric bacteria and 15 antibiotic resistance genes (ARGs) were sought by real-time polymerase chain reaction (qPCR) performed directly on rectal samples. ARG-positive samples were further tested by conventional PCR and sequencing. We evidenced a 17.5% prevalence of gastrointestinal symptoms, a 9.6% prevalence of enteric pathogenic bacteria carriage, including Escherichia coli pathotypes (8.7%) and Tropheryma whipplei (0.9%). Only 2 persons carried bla CTX-M-15 resistance genes (1.8%), while other genes, including carbapenemase-encoding genes and colistin-resistance genes, (mcr-1 to mcr-6, mcr-8) were not detected. Our results suggest that sheltered homeless persons in Marseille do not have a high risk of harbouring gastrointestinal antibiotic resistant bacteria.

Abstract

The aim of this study was to assess how red-eared sliders (Trachemys scripta elegans) respond to anaesthesia itself and coelioscopy. For that purpose, the turtles were anaesthetised with ketamine–medetomidine or propofol, and the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione S-transferase (GST) and the level of malondialdehyde (MDA) were determined by spectrophotometry. The possible genotoxic effects of the anaesthetic agents were estimated by comet assay. A total of 24 turtles were included in this study. The animals were divided into four groups according to the anaesthetic protocol and according to whether endoscopy would be performed. Significantly decreased activities of CAT were found only in the propofol group and in turtles undergoing coelioscopy. Both anaesthetic protocols induced significantly increased MDA levels, while no differences were observed after the intervention. A significant increase in GST activity was detected in turtles after both anaesthetic protocols, but after coelioscopy significant changes in GST activity were found only in the propofol group. However, no differences in SOD activity and no DNA damages were detected in either group. These findings suggest that ketamine–medetomidine may be more suitable anaesthetic agents in red-eared sliders than propofol.

Abstract

Bacteriological cultures from cerebrospinal fluids (CSF) have less sensitivity and specificity compared to quantitative PCR (RT-PCR), and multiple facts still conduct to the increase of negative culture. The aims of this study are to determine the molecular epidemiology and the simultaneous detection of bacterial meningitis in Morocco by using RT-PCR and compared this molecular approach with culture method to improve the etiological diagnosis of meningitis. The CSFs were collected over one-year period in 2018 in different hospitals covering all regions of the Kingdom of Morocco, from patients with suspected meningitis. The results showed the confirmation rate per culture recorded a rate of 33% and the RT-PCR of 70%. Molecular epidemiology is predominant of Neisseria meningitidis followed by Streptococcus pneumoniae and a dramatic reduction in meningitis due to Haemophilus influenzae following the introduction of conjugate vaccine in 2007. Also, the epidemiological profile shows a sex ratio M/F of 1.4 and a median age of 2 years. The national distribution showed a predominant of meningococcal disease followed by pneumococcal disease, especially a dominance of N. meningitidis over S. pneumoniae in two regions and a slight predominance of S. pneumoniae in the other two regions over N. meningitidis. Our research shows that culture in our country has less sensitivity and specificity than RT-PCR in diagnosis of bacterial meningitis and that molecular biology technique at bacteriology laboratories is desirable for diagnosis, early management of meningitis cases and in the context of the surveillance of meningitis in Morocco in parallel with culture.

Abstract

Scientists around the world are focusing their interest on the use of probiotics in honey bees as an alternative method of prophylaxis against causative agents of both American and European foulbrood. In our study we tested inhibitory activity against Paenibacillus larvae and the biofilm formation activity by various lactic acid bacteria isolated from honey bee guts or fresh pollen samples in the presence of different sugars added to the cultivation media. In addition, we tested the probiotic effect of a newly selected Apilactobacillus kunkeei V18 in an in situ experiment in bee colonies. We found antibacterial activity against P. larvae in four isolates. Biofilm formation activity of varying intensity was noted in six of the seven isolates in the presence of different sugars. The strongest biofilm formation (OD570 ≥ 1) was noted in A. kunkeei V18 in the presence of fructose; moreover, this isolate strongly inhibited the growth of P. larvae under laboratory conditions. Inhibition of P. larvae and Melissococcus plutonius by A. kunkeei V18 in situ was confirmed in a pilot study.

Összefoglaló. Bevezetés: A COVID–19-járvány az egész világon elterjedt. A járvány Európában való első megjelenése során megfigyelhető volt, hogy a terjedés mértéke kisebb azokban az országokban, ahol a tuberkulózis elleni védekezésül kiterjedt BCG-vakcinációt végeznek. Célkitűzés: A jelen munkában olyan összefüggéseket igyekeztünk feltárni, amelyek befolyásolták a járványterjedés paramétereit, különös figyelemmel a BCG-vakcinációs gyakorlatra. Módszerek: A világ összes olyan országára vonatkozóan, ahol megfelelő minőségű statisztikai adatok álltak rendelkezésünkre, vizsgáltuk a járvány terjedésének első hullámát. A mozgóátlagolt járványgörbéken elemeztük a járvány időtartamát, a tetőzés mértékét, a fertőzöttek és a halálesetek egymillió lakosra vetített számát. Figyelembe vettük az országok gazdasági mutatóit (GDP, légi forgalom, a tengeri hajózás mértéke). Statisztikai analízis: A vizsgált paraméterek nem mutattak normális eloszlást, így nemparaméteres próbákkal (rangkorreláció, Kruskal–Wallis ANOVA) statisztikai kapcsolatot kerestünk a járványterjedés mértéke, a BCG-vakcináció és más paraméterek között. Eredmények: A járvány gyorsan elterjedt a világon, de mégis, február első három hetében a terjedésben egy szünet volt megfigyelhető. A járványhullám Európában nagyjából egyszerre ért véget. A járvány által leginkább azok az országok érintettek, ahol nem alkalmaztak rendszeres BCG-vakcinációt, bár a képet bonyolítja, hogy ezek az országok gazdaságilag többnyire fejlettek. A halálozási rátában nem mutatkozott ilyen különbség. Következtetés: Statisztikailag igazolható tény, hogy a vakcinációt végző országokból az első hullám alatt kevesebb fertőzöttet jelentettek; az ok-okozati összefüggés bizonytalan, hiszen az országok múltja, szokásai, társadalmi berendezkedése, gazdasági fejlettsége nem azonos. Eredményeink alátámasztják az összehasonlító kontaktkutatás fontosságát annak tisztázására, hogy a BCG-oltás hogyan befolyásolja az emberek vírussal szembeni érzékenységét, valamint a vírus terjesztésének, továbbadásának képességét.

Summary. Introduction: The new type of coronavirus (SARS-CoV-2) epidemic is widespread throughout the world. During the outbreak of the pandemic in Europe it was revealed that the rate of spread was lower in countries where extensive BCG vaccination is used to protect against tuberculosis. Objective: In the present work, we sought to explore relationships that influenced epidemic spreading parameters, with particular reference to BCG vaccination practice. Methods: We examined the first wave of the spread of the epidemic for all countries in the world where adequate quality statistics were available. We analyzed the duration of the epidemic, the extent of the peak, the number of infected people, and the number of deaths per million inhabitants with the moving average of epidemic curves. We took into account the economic indicators of the countries (GDP, air traffic and extent of maritime shipping). Statistical analysis: The examined parameters did not show a normal distribution, so we looked for a statistical relationship with non-parametric tests (rank correlation, Kruskal–Wallis ANOVA) between the extents of epidemic spread, BCG vaccination and other parameters. Results: The epidemic spread rapidly around the world, but still, in the first three weeks of February, there was a pause in the spread. The first wave of epidemics ended roughly at the same time in Europe. Those countries are the most affected by the epidemic where regular BCG vaccination has not been used, although the picture is complicated by the fact that these countries are mostly economically developed. There was no such difference observable in the mortality rate. Conclusion: Although this work clearly demonstrates that during the first wave of the pandemic, fewer infections were reported worldwide in countries where BCG vaccination is obligatory, however, the causal relationship is uncertain, as the countries’ past, customs, social organization and economic development are different. Our results support the necessity of comparative contact tracing to clarify how BCG vaccination affects people’s susceptibility to this new type of coronavirus as well as their ability to spread and transmit the virus.

Összefoglaló. Bevezetés: A cerebrovascularis betegségek népegészségügyi szempontból jelentősek, világszerte a vezető halálokok között szerepelnek, és a rokkantság egyik fő okát képezik. Célkitűzés: Vizsgálatunk célja a cerebrovascularis betegségekből eredő, idő előtti halálozás hazai és nemzetközi adatainak elemzése régiónkénti bontásban a 45–59 éves korcsoportban. Módszerek: Retrospektív, kvantitatív elemzés keretében vizsgáltuk a cerebrovascularis betegségekből eredő, korspecifikus, 1990 és 2014 közötti halálozást az Egészségügyi Világszervezet (WHO) Európai Régióján belül kiválasztott nyugat-európai (n = 17), kelet-európai országokban (n = 10) és a volt Szovjetunió utódállamaiban (n = 15), 100 000 főre vetítve, a WHO Európai Halálozási Adatbázisának adatai alapján. Leíró statisztikai módszereket, idősoros kimutatást, Kruskal–Wallis-próbát alkalmaztunk. Eredmények: A cerebrovascularis betegségekből eredő, 100 000 főre vetített korspecifikus halálozás a nyugat-európai országokban volt a legalacsonyabb (férfiak: 1990: 35,14, 2014: 14,31; nők: 1990: 21,11, 2014: 8,76) és a Szovjetunió utódállamaiban a legmagasabb (férfiak: 1990: 134,19; 2014: 91,13; nők: 1990: 83,62, 2014: 41,83) (p<0,05). A kelet-európai és a nyugat-európai országok, valamint a nyugat-európai országok és a Szovjetunió utódállamainak korspecifikus, cerebrovascularis halálozása között szignifikáns különbséget találtunk mindkét nemben (1990, 2004, 2014: p<0,05). A cerebrovascularis betegségek korspecifikus standardizált halálozása 1990 és 2014 között a nyugat-európai országokban (férfiak: –59,28%, nők: –58,29%) csökkent a legnagyobb mértékben, melyet a vizsgált kelet-európai országok (férfiak: –54,14%, nők: –57,53%), majd a Szovjetunió utódállamai (férfiak: –32,09%, nők: –49,97%) követtek. Következtetések: A korspecifikus, cerebrovascularis halálozás a férfiak és a nők körében egyaránt csökkent az egyes régiókban. Magyarországon a nyugat-európai átlagnál jobban, 62,2%-kal csökkent a férfiak és 59,1%-kal a nők korai cerebrovascularis halálozása 1990 és 2014 között. Orv Hetil. 2021; 162(4): 144–152.

Summary. Introduction: Cerebrovascular diseases are a significant public health concern, they are among the leading causes of death worldwide and one of the major causes of disability. Objective: Our aim was to analyse national and international data regarding premature, cerebrovascular disease mortality per region in the 45–59 age group. Methods: We performed a retrospective, quantitative analysis on age-specific, premature cerebrovascular disease mortality between 1990 and 2014 per 100 000 population on data derived from the World Health Organisation, European Mortality Database on Western European (n = 17), Eastern European (n = 10) countries, and countries of the former Soviet Union (n = 15). Descriptive statistics, time series analysis and Kruskal–Wallis test were performed. Results: Age-related, cerebrovascular disease mortality per 100 000 population was the lowest in Western European countries (males: 1990: 35.14, 2014: 14.31; females: 1990: 21.11, 2014: 8.76), and the highest in former Soviet Union countries (males: 1990: 134.19; 2014: 91.13; females: 1990: 83.62, 2014: 41.83) (p<0,05). Significant differences were found in age-specific, cerebrovascular disease mortality in both sexes between Eastern and Western European countries and former Soviet Union countries (1990, 2004, 2014: p<0.05). Between 1990 and 2014, age-specific, standardized cerebrovascular disease mortality showed the biggest decrease in Western European countries (males: –59.28%, females: –58.29%) followed by Eastern European (males: –54.14%, females: –57.53%) and former Soviet Union countries (males: –32.09%, females: –49.97%). Conclusions: Age-specific, cerebrovascular disease mortality decreased in both sexes in all regions analysed. Hungary was found to have seen a decrease above the Western European average, premature cerebrovascular mortality decreased by 62.2% in males and 59.1% in females between 1990 and 2014.
