Abstract
Accurate characterisation of gastrointestinal stromal tumours (GIST) is important for prognosis and the choice of targeted therapies. Histologically the diagnosis relies on positive immunostaining of tumours for KIT (CD117) and DOG1. Here we report that GISTs also abundantly express the type 3 Sarco/Endoplasmic Reticulum Calcium ATPase (SERCA3). SERCA enzymes transport calcium ions from the cytosol into the endoplasmic reticulum and play an important role in regulating the intensity and the periodicity of calcium-induced cell activation. GISTs from various localisations, histological and molecular subtypes or risk categories were intensely immunopositive for SERCA3 with the exception of PDGFRA-mutated cases where expression was high or moderate. Strong SERCA3 expression was observed also in normal and hyperplastic interstitial cells of Cajal. Decreased SERCA3 expression in GIST was exceptionally observed in a zonal pattern, where CD117 staining was similarly decreased, reflecting clonal heterogeneity. In contrast to GIST, SERCA3 immunostaining of spindle cell tumours and other gastrointestinal tumours resembling GIST was negative or weak. In conclusion, SERCA3 immunohistochemistry may be useful for the diagnosis of GIST with high confidence, when used as a third marker in parallel with KIT and DOG1. Moreover, SERCA3 immunopositivity may be particularly helpful in cases with negative or weak KIT or DOG1 staining, a situation that may be encountered de novo, or during the spontaneous or therapy-induced clonal evolution of GIST.

Abstract
Egy 13 éves fiú lázzal, köhögéssel, szaglásvesztéssel és kb. 2 × 3 cm átmérőjű,
jobb oldali nyaki elváltozással jelentkezett hozzátartozójának kíséretében
kórházunk gyermekgyógyászati szakambulanciáján. A vizsgálat előtt 24 nappal a
dokumentált nasopharyngealis COVID–19-gyorstesztje pozitivitást mutatott. Mivel
az ultrahangvizsgálaton beolvadási jeleket nem tapasztaltak, orális
antibiotikumterápiát (klaritromicin, 2 × 500 mg) javasoltak 7 napig, szerológiai
vizsgálatokra vért vettek. A beteg 2 nap elteltével újból jelentkezett az
elváltozás progresszív növekedése miatt. Osztályunkon vékonytű-biopszia,
valamint nyaki és mellkasi CT-vizsgálatok történtek. A citológiai vizsgálat
C3-diagnózissal zárult anélkül, hogy egyértelműen kizárta volna az aspirált
sejtek rosszindulatú jellemzőit. A nyaki és mellkasi CT kb. 60 × 46 × 40 mm-es,
supraclavicularisan elhelyezkedő inhomogén nyaki daganatot írt le, az
intrathoracalis régió inváziója nélkül, tályogképződés lehetséges jeleivel,
azonos oldali vena jugularis kompresszióval. Idővel a Bartonella
henselae szerológiai vizsgálat pozitivitást mutatott. A nyaki
képlet műtéti eltávolítása mellett döntöttünk. Szövettani vizsgálattal
nekrotizáló és nem nekrotizáló granulomák voltak kimutathatók atípusos sejtek
jelenléte nélkül. Ezek és a szerológiai eredmény alapján a bartonellosis
diagnózisát állítottuk fel. Bár a SARS-CoV-2-fertőzés hatásáról a bartonellosis
klinikai lefolyására az irodalomban nem találtunk adatot, esetünk kapcsán
elképzelhetőnek tartjuk, hogy a COVID–19 által legyengített szervezetben a
bakteriális fertőzés az egyébként ártalmatlan betegség helyett a bartonellosis
súlyosabb klinikai képét okozta, melynek megoldását a gyógyszeres kezelésre
nehezen reagáló nyaki elváltozás teljes eltávolítása jelentette. Orv Hetil.

Abstract
NTRK-rearranged uterine sarcoma is a recently described entity that represents a subset of uterine sarcomas with distinct clinicopathological features. From a molecular point of view, this tumour is defined by NTRK gene rearrangement, resulting in overexpression or constitutive activation of Trk receptors. The presence of NTRK fusion is indicative of treatment response with a selective small-molecule inhibitor of the Trk kinases. Here, we report a case of an NTRK-rearranged sarcoma of the uterine cervix in a 43-year-old patient, measuring 80 mm in its largest dimension, with a novel NUMA1-NTRK1 fusion, not previously reported in NTRK-rearranged uterine sarcomas or other NTRK-rearranged tumours. The fusion, involving NUMA1 exon 14 (NM_006185.4) and NTRK1 exon 11 (NM_002529.4), was identified by next-generation sequencing (NGS) studies (FusionPlex Pan Solid Tumor v2 panel). Although the presence of NTRK fusion has been reported in a variety of neoplasms, a fusion involving NUMA1 (nuclear mitotic apparatus protein 1) and a tyrosine kinase partner has previously been reported in human neoplasms only in a handful of cases. The resulting fusion protein comprises the oligomerization domain of NUMA1, which is predicted to cause constant activation of the tyrosine kinase domain of NTRK1. The recognition and accurate diagnosis of these tumours are important due to the availability of potential targeted therapeutic options.

Abstract
A papillaris pajzsmirigyrák prognózisát a gyakori nyaki nyirokcsomóáttét-képzés
befolyásolja. Sebészi kezelésük minősége a betegek túlélését és a recidíva
előfordulási gyakoriságát is meghatározza. Az Országos Onkológiai Intézet
Fej-Nyaki Daganatok Multidiszciplináris Központjában a fej-nyak sebész szerzők
által 2013 és 2018 között operált, nyaki áttétet adó papillaris carcinomás
betegek adatait vizsgáltuk. 130, nyaki áttétet adó papillaris
pajzsmirgy-carcinomás beteg esetében az ATA (American Thyroid Association) 2015.
évi irányelvei alapján teljes pajzsmirigy-eltávolítást és nyaki
nyirokcsomó-dissectiót végeztünk. Az eltávolított anyagokat szövettani
feldolgozásra küldtük, vizsgáltuk a nyirokcsomóáttét(ek) arányát az életkor, a
nem, a tumor-multifokalitás, a kétoldaliság, a tokon kívüli terjedés, a nyirok-,
érinvázió függvényében. Elemeztük a műtét után fellépő szövődményeket is. 43
betegnél thyreoidectomia, totális és centrális nyaki dissectio (VI. régió), 87
esetben centrális (VI. régió) és laterális (II–V. régió) nyaki dissectio
történt. Átmeneti (6 hónapon belül normalizálódó) hypocalcaemia 30 betegnél
(23%), permanens hypocalcaemia 4 betegnél (3%) fordult elő. Átmeneti nervus
recurrens bénulás 12 esetben (9,2%), permanens bénulás 3 (2,3%) esetben történt.
A szövettani értékeléskor érbetörés és tokinvázió 75 betegnél (57,7%),
nyirokér-invázió 63 betegnél (48,5%), Hashimoto-thyreoiditis 51 betegnél (39,2%)
igazolódott. Microcarcinoma (1 cm-nél kisebb daganat) 43 esetben fordult elő
(33%). Az eltávolított nyirokcsomók átlagosan 48%-a volt áttétes. Ez csak a
tumormérettel mutatott szignifikáns korrelációt, az életkorral nem találtunk
összefüggést. Az oldaliság, a többgócúság, valamint a tok-, nyirokér- és
érinvázió, a Hashimoto-status és a beteg neme nem mutatott összefüggést az
áttétes nyirokcsomók számával. A túlélést befolyásolta a tok-, ér- és
nyirokér-invázió, valamint a tumorméret is. A nyaki áttétet adó, differenciált
pajzsmirigyrákos beteganyagunk kezelésében a kivizsgálási protokollt követően a
teljes pajzsmirigy-eltávolítás és a megfelelő régiókat tartalmazó nyaki
dissectio döntő fontosságú, a radiojód-terápiával kiegészítve az irányelveknek
megfelelő kezelési modul. A pajzsmirigydaganat a leggyakoribb endokrin daganatos
megbetegedés, melynek sebészi kezelése a multidiszciplináris terápia
legfontosabb eleme. 5 év alatt operált, nyaki áttétet is adó, differenciált
pajzsmirigyrákos beteganyagunkat feldolgozva ismertetjük eredményeinket az
olvasóval. Orv Hetil. 2024; 165(3): 83–88.

Abstract
INTRODUCTION POLE mutant phenotype in colon adenocarcinomas represents a rare molecular subtype. These tumours are generally responsive to immune-checkpoint inhibition therapy and, therefore, are currently considered as a subtype with good prognosis. We hereby present the first detailed case presentation of a POLE mutant colon adenocarcinoma with useful microscopic features. CASE REPORT A 53-year-old male patient's colon adenocarcinoma histologically showed wide variety of growth patterns and massive intra- and peritumoural lymphocytic infiltrate. The majority of the tumour consisted of a high-grade component resembling medullary carcinoma of the colon, while approximately one-third of the tumour was composed of conventional areas exhibiting a tubular pattern. A minority of the tumour was constituted by poorly cohesive rhabdoid cells. Immunohistochemistry was performed, and colorectal origin was proven with CDX-2 and SATB2. Furthermore, proficiency in mismatch repair proteins and SMARCB1 deficiency was observed. The unusually high-grade colon adenocarcinoma, with areas mimicking medullary carcinoma, and generally aggressive morphology raised suspicion of microsatellite instability. The diverse morphology and the SMARCB1 deficiency also raised suspicion of ultramutation caused by POLE alteration. Next-generation sequencing panel confirmed a pathogenetic mutation in POLE exon 9: p.Pro286Arg, c.857C > G. DISCUSSION The diverse, high-grade morphology and increased intratumoural lymphoid infiltration should raise suspicion for POLE-mutated adenocarcinoma during everyday histopathological practice. Mismatch repair proficiency results on immunohistochemistry should not determine the final diagnosis, as only a minor percentage of these tumours are MSI. In every case suspicious for POLE-mutated adenocarcinoma, a 500-cancer gene panel should be carried out.

Abstract
A Gram-stain-negative strain, designated as D2M1T was isolated from xylene-degrading enrichment culture and characterized using a polyphasic approach to determine its taxonomic position. The 16S rRNA gene sequence analysis revealed that strain D2M1T belongs to the genus Acidovorax, with the highest 16S rRNA gene similarity to Acidovorax delafieldii DSM 64T (99.93 %), followed by Acidovorax radicis DSM 23535T (98.77 %) and Acidovorax kalamii MTCC 12652T (98.76 %). The draft genome sequence of strain D2M1T is 5.49 Mb long, and the G+C content of the genome is 64.2 mol%. Orthologous average nucleotide identity and digital DNA-DNA hybridization relatedness values between strain D2M1T and its closest relatives were below the threshold values for species demarcation confirming that strain D2M1T is distinctly separated from its closest relatives. The whole genome analysis of the strain revealed a phenol degradation gene cluster, encoding a multicomponent phenol hydroxylase (mPH) together with a complete meta-cleavage pathway including an I.2.C-type catechol 2,3-dioxygenase (C23O) gene. The strain was able to degrade benzene and ethylbenzene as sole sources of carbon and energy under aerobic and microaerobic conditions. Cells were facultatively aerobic rods and motile with a single polar flagellum. The predominant fatty acids (>10 % of the total) of strain D2M1T were summed feature 3 (C16 : 1 ω7c/C16 : 1 ω6c), C16 : 0 and summed feature 8 (C18 : 1 ω7c/C18 : 1 ω6c). The major ubiquinone of strain D2M1T was Q8, while the major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. Based on polyphasic data, it is concluded that strain D2M1T represents a novel species of the genus Acidovorax, for which the name of Acidovorax benzenivorans sp. nov. is proposed. The type strain of the species is strain D2M1T (=DSM 115238T=NCAIM B.02679T).

Abstract
Peripheral T-cell lymphomas (PTCLs) expressing multiple follicular T helper (TFH) cell-related antigens are now classified as TFH lymphomas (TFHL), including angioimmunoblastic, follicular, and not otherwise specified (NOS) types. CXCR5 is the TFH cell-defining chemokine receptor that, together with its ligand CXCL13, plays a critical role in the development of follicles and the positioning of TFH and B cells within follicles. A comprehensive immunomorphologic study was performed to investigate the expression pattern of CXCR5 in a large cohort of nodal PTCLs, particularly those with a TFH cell phenotype, and to compare its expression with six other TFH cell-related antigens. We found that CXCR5 is widely expressed in neoplastic TFH cells, except in TFHL-NOS, and represents a specific marker of this lymphoma entity. Our results suggest that CXCR5 directs the distribution of neoplastic T cells in the affected lymph nodes and may influence the formation of the pathognomic pathological FDC network.

Abstract
In this study, a Gram-stain-positive, non-motile, oxidase- and catalase-negative, rod-shaped, bacterial strain (SG_E_30_P1T) that formed light yellow colonies was isolated from a groundwater sample of Sztaravoda spring, Hungary. Based on 16S rRNA phylogenetic and phylogenomic analyses, the strain was found to form a distinct linage within the family Microbacteriaceae. Its closest relatives in terms of near full-length 16S rRNA gene sequences are Salinibacterium hongtaonis MH299814 (97.72 % sequence similarity) and Leifsonia psychrotolerans GQ406810 (97.57 %). The novel strain grows optimally at 20-28 °C, at neutral pH and in the presence of NaCl (1-2 w/v%). Strain SG_E_30_P1T contains MK-7 and B-type peptidoglycan with diaminobutyrate as the diagnostic amino acid. The major cellular fatty acids are anteiso-C15 : 0, iso-C16 : 0 and iso-C14 : 0, and the polar lipid profile is composed of diphosphatidylglycerol and phosphatidylglycerol, as well as an unidentified aminoglycolipid, aminophospholipid and some unidentified phospholipids. The assembled draft genome is a contig with a total length of 2 897 968 bp and a DNA G+C content of 65.5 mol%. Amino acid identity values with it closest relatives with sequenced genomes of <62.54 %, as well as other genome distance results, indicate that this bacterium represents a novel genus within the family Microbacteriaceae. We suggest that SG_E_30_P1T (=DSM 111415T=NCAIM B.02656T) represents the type strain of a novel genus and species for which the name Antiquaquibacter oligotrophicus gen. nov., sp. nov. is proposed.

Abstract
Increasing metal(loid) contamination in urban soils and its impact on soil microbial community have attracted considerable attention. In the present study, the physicochemical parameters and the effects of twelve metal(loid) pollution on soil microbial diversity, their ecotoxic effects, and human health risk assessment in urban soils with different industrial background were studied in comparison with an unpolluted forest soil sample. Results showed that urban soils were highly contaminated, and metal(loid) contamination significantly influenced structure of the soil microbial communities. In all samples the bacterial community was dominated by Proteobacteria, and on the level of phyla characteristic differences were not possible to observe between polluted and control sampling sites. However, clear differences emerged at class and genus level, where several rare taxa disappeared from contaminated urban soils. Simper test results showed that there is 71.6 % bacterial OTU and 9.5 % bacterial diversity dissimilarity between polluted and control samples. Ratio of Patescibacteria, Armatimonadetes, Chlamydiae, Fibrobacteres, and Gemmatimonadetes indicated a significant (p < 0.05) positive correlation with soil Zn, Cr, Pb, Sn, Cu, Mn content, suggest that metal(loid)s strongly influence the structure of microbial community. In contrast, the presence of metal(loid) contamination in urban soils has been found to significantly reduce the population of Archaeal communities. This can be attributed to the depletion of organic matter caused by contamination that reached a minimum of 0.5 m/m% for nitrate and 0.9 m/m% for total organic carbon. The values of urban soil pH were close to neutral, ranging from 5.9 to 8.3. The findings of ecotoxicology test are alarming, as all the studied urban soil sites were cytotoxic to soil microorganisms, and in one site metal(loid) contamination reached genotoxic level. Moreover, all the metal(loid) contaminated sites pose severe and persistent health risk to children, highlighting the urgent need for effective measures to mitigate metal(loid) pollution in urban areas.

Abstract
Primary squamous cell carcinoma (SCC) of the thyroid gland is now considered as a member of the anaplastic thyroid carcinoma group based on the latest version of the WHO tumor classification. It is a very rare entity, the prognosis is adverse with a short survival time. The aim of this article is to emphasize the therapeutic complexity of this disease. A 68-year-old woman presented with rapidly growing right-sided neck mass with hoarseness and compressive symptoms. Physical examination revealed a hard fixed tumor with right-sided vocal cord palsy. Fine-needle aspiration cytology revealed a case of SCC in the location of the thyroid gland, imaging studies excluded the possibility of other primary malignancies. Surgical intervention was performed aiming the total removal of the tumor. Histopathological result confirmed the diagnosis of SCC of the thyroid. Finally the patient died during the palliative radiation therapy. SCC of the thyroid gland is a great challenge for both the surgeon and the multidisciplinary team to come up with the best treatment option which is suitable for the patient due to its unfavorable prognosis. Because of the poor response to the radiation and chemotherapy, complete surgical removal and the identification of any possible targetable molecular pathological change play a unique role in the therapy.

Abstract
Case-report Rosai-Dorfman disease, also known as sinus histiocytosis with massive lymphadenopathy is a rare, benign non-Langerhans cell histiocytosis, that typically involves the lymph nodes, but may also involve extranodal sites. We present a 58- years- old female patient who complained of a palpable mass in her left breast surrounded by 15-20 livid cutaneous lesions, resembling malignant breast cancer with cutaneous metastasis. Despite of core biopsy of the tumor and excisional biopsy one of the lesions, correct diagnosis of RDD was achieved only by complete pathological examination of the whole lesion after surgical excision. Conclusion Rosai-Dorfman disease confined to the breast is extremely rare, that clinically may mimic breast cancer.

Abstract
BACKGROUND Recent genomic studies revealed enhancer of zeste homolog 2 (EZH2) gain-of-function mutations, representing novel therapeutic targets in follicular lymphoma (FL) in around one quarter of patients. However, these analyses relied on single-site tissue biopsies and did not investigate the spatial heterogeneity and temporal dynamics of these alterations. OBJECTIVES We aimed to perform a systematic analysis of EZH2 mutations using paired tissue (tumor biopsies [TB]) and liquid biopsies (LB) collected prior to treatment within the framework of a nationwide multicentric study. METHODS Pretreatment LB and TB samples were collected from 123 patients. Among these, 114 had paired TB and LB, with 39 patients characterized with paired diagnostic and relapse samples available. The EZH2 mutation status and allele burden were assessed using an in-house-designed, highly sensitive multiplex droplet digital PCR assay. RESULTS EZH2 mutation frequency was found to be 41.5% in the entire cohort. In patients with paired TB and LB samples, EZH2 mutations were identified in 37.8% of the patients with mutations exclusively found in 5.3% and 7.9% of TB and LB samples, respectively. EZH2 mutation status switch was documented in 35.9% of the patients with paired diagnostic and relapse samples. We also found that EZH2 wild-type clones may infiltrate the bone marrow more frequently compared to the EZH2 mutant ones. CONCLUSION The in-depth spatio-temporal analysis identified EZH2 mutations in a considerably higher proportion of patients than previously reported. This expands the subset of FL patients who most likely would benefit from EZH2 inhibitor therapy.

Abstract
Histiocytic sarcoma is an uncommon hematological malignancy. Its occurrence in the lung is very rare. Due to the small number of cases and the clinical and pathological features of the disease, the diagnosis can be challenging. Its optimal treatment is not yet known, in locally confined cases - depending on the location and size - surgical removal is part of complex oncotherapy. We report the case of a 52-year-old man with a tumor of central localization in the left lung. Pulmonectomy was performed. Histology verified histiocytic sarcoma of the lung. An overview of clinical features of the entity is presented in connection with our case report. Orv Heti. 2023; 164(34): 1350-1357.

Abstract
BACKGROUND Oral or laryngeal leukoplakia has an increased risk for malignant transformation but the risk of the two anatomical sites has not been compared to each other yet. MATERIALS AND METHODS Clinical data of 253 patients with leukoplakia (oral = 221 or laryngeal = 32) enrolled from January 1996 to January 2022 were analyzed. One hundred and seventy underwent biopsy and 83 did not. The mean follow-up time was 148.8 months. Risk factors for the malignant transformation of leukoplakia were identified using Cox proportional hazard models. RESULTS In the oral or laryngeal group, the rate of cancer was 21.7% and 50% (p = 0.002), respectively. The 10-year estimated malignant transformation was 15.1% and 42% (p < 0.0001), respectively. The laryngeal group had an increased risk of malignant transformation (p < 0.0001). The 5-year estimated survival with leukoplakia-associated cancer for the oral or laryngeal group was 40.9% and 61.1% (p = 0.337), respectively. Independent predictors of malignant transformation in the oral group were dysplasia and the grade of dysplasia of the leukoplakia, and in the laryngeal group, dysplasia had a significant impact. The malignant transformation rate was low for oral patients without biopsy or with no dysplasia, 3.9% and 5.1%, respectively. The malignant transformation occurred over 10 years. CONCLUSIONS Patients with dysplastic leukoplakia have an increased risk of malignant transformation, but the risk is higher with laryngeal than with oral leukoplakia. There is no significant difference between the groups regarding survival with leukoplakia-associated cancer. Oral patients with no dysplastic lesions have a low risk of malignant transformation. A complete excision and long-term follow up are suggested for high-risk patients to diagnose cancer in an early stage and to control late (over 10 years) malignant events.

Abstract
The incidence of cancer is rising significantly in Hungary and worldwide. It is one of the leading causes of both morbidity and mortality. In recent years, the advent of personalised treatments and targeted therapies have brought significant advances in the treatment of cancer. Targeted therapies are based on the identification of genetic variations in patients' tumour tissue. However, tissue or cytological sampling poses a number of difficulties, while non-invasive procedures such as liquid biopsy studies can be a good alternative to overcome these problems. In nucleic acids from liquid biopsy samples, circulating tumour cells or free circulating tumour DNA, RNA present in the plasma the same genetic abnormalities can be detected that are present in tumours and their quantification is suitable for therapy monitoring and prognosis estimation. In our summary, we describe the advantages and difficulties of liquid biopsy specimen analysis and its potential for use in everyday clinical practice for molecular diagnosis of solid tumours.

Abstract
The genus Belliella belongs to the family Cyclobacteriaceae (order Cytophagales, phylum Bacteroidota) and harbours aerobic chemoheterotrophic bacteria. Members of this genus were isolated from various aquatic habitats, and our analysis based on global amplicon sequencing data revealed that their relative abundance can reach up to 5-10 % of the bacterioplankton in soda lakes and pans. Although a remarkable fraction of the most frequent genotypes that we identified from continental aquatic habitats is still uncultured, five new alkaliphilic Belliella strains were characterized in detail in this study, which were isolated from three different soda lakes and pans of the Carpathian Basin (Hungary). Cells of all strains were Gram-stain-negative, obligate aerobic, rod-shaped, non-motile and non-spore-forming. The isolates were oxidase- and catalase-positive, red-coloured, but did not contain flexirubin-type pigments; they formed bright red colonies that were circular, smooth and convex. Their major isoprenoid quinone was MK-7 and the predominant fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH and summed feature 3 containing C16 : 1 ω6c and/or C16 : 1 ω7c. The polar lipid profiles contained phosphatidylethanolamine, an unidentified aminophospholipid, an unidentified glycolipid, and several unidentified lipids and aminolipids. Based on whole-genome sequences, the DNA G+C content was 37.0, 37.1 and 37.8 mol % for strains R4-6T, DMA-N-10aT and U6F3T, respectively. The distinction of three new species was confirmed by in silico genomic comparison. Orthologous average nucleotide identity (<85.4 %) and digital DNA-DNA hybridization values (<38.9 %) supported phenotypic, chemotaxonomic and 16S rRNA gene sequence data and, therefore, the following three novel species are proposed: Belliella alkalica sp. nov. (represented by strains R4-6T=DSM 111903T=JCM 34281T=UCCCB122T and S4-10), Belliella calami sp. nov. (DMA-N-10aT=DSM 107340T=JCM 34280T=UCCCB121T) and Belliella filtrata sp. nov. (U6F3T=DSM 111904T=JCM 34282T=UCCCB123T and U6F1). Emended descriptions of species Belliella aquatica, Belliella baltica, Belliella buryatensis, Belliella kenyensis and Belliella pelovolcani are also presented.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are increasingly recognized as potential environmental contaminants that may induce toxicity in aquatic ecosystems. This 3-week microcosm experiment explores the acute impacts of NSAIDs, including diclofenac (DCF), ibuprofen (IBU), and acetylsalicylic acid (ASA), on bacterial communities using a wide range of these substances (200-6000 ppm). The results showed that the NSAID-treated microcosms had higher cell count values than control samples, though the diversity of microbial communities decreased. The isolated heterotrophic bacteria mostly belonged to Proteobacteria, particularly Klebsiella. Next-generation sequencing (NGS) revealed that NSAIDs altered the structure of the bacterial community composition, with the proportion of Proteobacteria aligning with the selective cultivation results. Bacteria had higher resistance to IBU/ASA than to DCF. In DCF-treated microcosms, there has been a high reduction of the number of Bacteroidetes, whereas in the microcosms treated with IBU/ASA, they have remained abundant. The numbers of Patescibacteria and Actinobacteria have decreased across all NSAID-treated microcosms. Verrucomicrobia and Planctomycetes have tolerated all NSAIDs, even DCF. Cyanobacteria have also demonstrated tolerance to IBU/ASA treatment in the microcosms. The archaeal community structure was also impacted by the NSAID treatments, with Thaumarchaeota abundant in all microcosms, especially DCF-treated microcosms, while Nanoarchaeota is more typical of IBU/ASA-treated microcosms with lower NSAID concentrations. These results indicate that the presence of NSAIDs in aquatic environments could lead to changes in the composition of microbial communities.

Abstract
Objective The aim of this study was to investigate how polarized sodium iodide symporter (NIS) expression may regulate iodide metabolism in vivo. Materials and methods Polarized NIS expression was analyzed in tissues that accumulate iodide by the use of immunohistochemistry and polyclonal antibody against the C-terminal end of human NIS (hNIS). Results Iodide absorption in the human intestine occurs via NIS expressed in the apical membrane. Iodide is secreted into the lumen of the stomach and salivary glands via NIS expressed in the basolateral membrane and then circulates back from the small intestine to the bloodstream via NIS expressed in the apical membrane. Conclusion Polarized NIS expression in the human body regulates intestinal-bloodstream recirculation of iodide, perhaps prolonging the availability of iodide in the bloodstream. This leads to more efficient iodide trapping by the thyroid gland. Understanding the regulation and manipulating gastrointestinal iodide recirculation could increase radioiodine availability during theranostic NIS applications.

Abstract
Background. The dual role of GCs has been observed in breast cancer; however, due to many concomitant factors, GR action in cancer biology is still ambiguous. In this study, we aimed to unravel the context-dependent action of GR in breast cancer. Methods. GR expression was characterized in multiple cohorts: (1) 24,256 breast cancer specimens on the RNA level, 220 samples on the protein level and correlated with clinicopathological data; (2) oestrogen receptor (ER)-positive and -negative cell lines were used to test for the presence of ER and ligand, and the effect of the GRβ isoform following GRα and GRβ overexpression on GR action, by in vitro functional assays. Results. We found that GR expression was higher in ER- breast cancer cells compared to ER+ ones, and GR-transactivated genes were implicated mainly in cell migration. Immunohistochemistry showed mostly cytoplasmic but heterogenous staining irrespective of ER status. GRα increased cell proliferation, viability, and the migration of ER- cells. GRβ had a similar effect on breast cancer cell viability, proliferation, and migration. However, the GRβ isoform had the opposite effect depending on the presence of ER: an increased dead cell ratio was found in ER+ breast cancer cells compared to ER- ones. Interestingly, GRα and GRβ action did not depend on the presence of the ligand, suggesting the role of the "intrinsic", ligand-independent action of GR in breast cancer. Conclusions. Staining differences using different GR antibodies may be the reason behind controversial findings in the literature regarding the expression of GR protein and clinicopathological data. Therefore, caution in the interpretation of immunohistochemistry should be applied. By dissecting the effects of GRα and GRβ, we found that the presence of the GR in the context of ER had a different effect on cancer cell behaviour, but independently of ligand availability. Additionally, GR-transactivated genes are mostly involved in cell migration, which raises GR's importance in disease progression.

Abstract
The authors of this manuscript are representatives of different subdisciplines of medicine, all of them are experienced researchers. As of their origin, they are practicing doctors from the primary care and from the clinical/hospital setting, diagnostics experts, researchers from healthcare management, health economics, representatives of patients' rights and patient organizations. They are all devoted to the implementation of personalized medicine and personalized healthcare in Hungary. The current manuscript - also meant to be a keynote message provoking further discussion in the medical community - is devoted to correcting for two false ideas. One is that personalized medicine is not yet ready for practical applications, it is merely a research area of futurologists. The other false idea is that only (or mainly) the lack of financial resources hinders the introduction of personalized healthcare in Hungary. Orv Hetil. 2023; 164(6): 202-209.

Abstract
Most of the neck node metastases from cancer of unknown primary (CUP) are squamous cell carcinomas (SCCs). The majority of which are human papillomavirus (HPV)-related, frequently show cystic morphology referring to Waldeyer's ring origin. Here, we report four cases of neck node SCCs metastases from CUP. In our institute, 432 patients with head and neck (HN) SCC underwent pretreatment mutagen sensitivity (MS) assay between 1996 and 2006. Among them, 4 patients ≤50 years of age had metastatic cervical nodes from CUP. The primary treatment was cervical node dissection ± radiotherapy. All patients had elevated (>1.0 chromatid break/cell) MS. One male patient died of progressive neck metastasis within 3 years and the 3 female patients are still alive more than 15 years after initial treatment of HPV+ (two) or cystic (one) SCC. Two female patients developed second and third distant site metachronous primary cancers. HPV+ or cystic HNSCC from CUP with elevated MS indicates good outcome. Distant site metachronous cancers of different histologic origins cannot be explained by field cancerization. The clinical significance of elevated MS in neck node SCC metastasis from CUP requires further investigation.

Abstract
BACKGROUND The use of checkpoint inhibitors has become increasingly important in the treatment of different cancers, including advanced muscle-invasive urothelial cancer and even in basal cell carcinoma. We present the case of a patient with advanced basal cell carcinoma and metastatic muscle-invasive urothelial cancer, who was treated with the programmed death-ligand 1 inhibitor, atezolizumab for both cancers. CASE PRESENTATION A 72-year-old Caucasian female patient, with a history of smoking without any comorbidities developed periocular basal cell carcinoma, which was surgically removed but relapsed 4 years later. Surgical excision was carried out twice, but with positive margins, therefore definitive radiotherapy was given. Subsequently, the patient developed non-muscle-invasive papillary urothelial carcinoma, which was removed by transurethral resection. Follow-up was irregular owing to the patient's inadequate compliance, and within 2 years, the patient's cancer relapsed and histology confirmed muscle-invasive urothelial carcinoma. Definitive radiochemotherapy was not accepted by the patient. Meanwhile, the patient's basal cell carcinoma had also progressed, despite receiving vismodegib therapy. Therefore, the patient was administered epirubicin-cisplatin. Having reached the maximum cumulative dose of epirubicin, treatment with this chemotherapeutic agent could not be continued. The patient developed bladder cancer metastasis in her left suprainguinal lymph nodes. Owing to the presence of both types of tumors, programmed death-ligand 1 inhibitor atezolizumab treatment was chosen. In just over 1 year, the patient received 17 cycles of atezolizumab altogether, which was tolerated well without any adverse or side effects. Follow-up imaging scans indicated complete remission of the metastatic bladder cancer and stable disease of the basal cell carcinoma. The patient subsequently passed away in hospital due to a complication of COVID-19 infection. CONCLUSIONS Our patient attained stable disease in advanced basal cell carcinoma and complete remission in metastatic muscle-invasive urothelial cancer after receiving programmed death-ligand 1 inhibitor, atezolizumab, therapy. To our knowledge, this is the first paper to report the use of programmed death-ligand 1 inhibitor, atezolizumab, as treatment for advanced basal cell carcinoma. This case may also be of interest for clinicians when treating patients with two synchronous cancers.

Abstract
In Hungary, there is no actual ovarian cancer guideline, despite this disease being the most lethal gynaecologic cancer. An expert panel was created by the Hungarian Society of Gynaecologic Oncologists to prepare a recommendation for the reatment of ovarian cancer patients. This multidisciplinary expert group worked together during the first trimester of 2022 using the guidelines and recommendations of the European Society of Gynaecologic Oncologists (ESGO) and the European Society for Medical Oncology (ESMO) and created the updated recommendations. This paper presents the recommended surgical and medical treatment of early, advanced stage and recurrent ovarian cancer.

Abstract
EGFR mutation in non-small cell lung cancer (NSCLC) offers a potential therapeutic target for tyrosine kinase inhibitor (TKI) therapy. The majority of these cases, however eventually develop therapy resistance, mainly by acquiring EGFR T790M mutation. Recently, third-generation TKIs have been introduced to overcome T790M mutation-related resistance. Cell free circulating tumor DNA (liquid biopsy) has emerged as a valuable alternative method for T790M mutation detection during patient follow up, when a tissue biopsy cannot be obtained for analysis. In this study, we summarized our experience with Super-ARMS EGFR Mutation Detection Kit (AmoyDx) on 401 samples of 242 NSCLC patients in a 3-year period in Hungary, comprising 364 plasma and 37 non-plasma samples. We also compared the performance of two commercially available detection kits, the cobas EGFR Mutation test v2 (Roche) and the Super-ARMS EGFR Mutation Detection Kit (AmoyDx). The same activating EGFR mutation was detected with the AmoyDx kit as in the primary tumor in 45.6% of the samples. T790M mutation was identified in 48.1% of the samples containing activating EGFR mutation. The detection rate of T790M mutation was not dependent on the DNA concentration of the plasma sample and there was no considerable improvement in mutation detection rate after a second, subsequent plasma sample. The concordance of EGFR activating mutation detection was 89% between the two methods, while this was 93% for T790M mutation detection. The AmoyDx kit, however showed an overall higher detection rate of T790M mutation compared to the cobas kit (p = 0.014). T790M mutation was detected at 29.8% of the patients if only plasma samples were available for analysis, while the detection rate was 70.2% in non-plasma samples. If the activating EGFR was detected in the plasma samples, the detection rate of T790M mutation was 42.4%. Although non-plasma samples provided a superior T790M mutation detection rate, we found that liquid biopsy can offer a valuable tool for T790M mutation detection, when a tissue biopsy is not available. Alternatively, a liquid biopsy can be used as a screening test, when re-biopsy should be considered in case of wild-type results.

Abstract
Members of the genus Pseudomonas are known to be widespread in hydrocarbon contaminated environments because of their remarkable ability to degrade a variety of petroleum hydrocarbons, including BTEX (benzene, toluene, ethylbenzene and xylene) compounds. During an enrichment investigation which aimed to study microaerobic xylene degradation in a legacy petroleum hydrocarbon-contaminated groundwater, a novel Gram-stain-negative, aerobic, motile and rod-shaped bacterial strain, designated as MAP12T was isolated. It was capable of degrading benzene, toluene, meta- and para- xylene effectively under both aerobic and microaerobic conditions. The 16S rRNA gene sequence analysis revealed that strain MAP12T belongs to the genus Pseudomonas, with the highest 16S rRNA gene similarity to Pseudomonas linyingensis LYBRD3-7T (98.42%), followed by Pseudomonas sagittaria JCM 18195T (98.29%) and Pseudomonas alcaliphila JCM 10630T (98.08%). Phylogenomic tree constructed using a concatenated alignment of 92 core genes indicated that strain MAP12T is distinct from any known Pseudomonas species. The draft genome sequence of strain MAP12T is 4.36 Mb long, and the G+C content of MAP12T genome is 65.8%. Orthologous average nucleotide identity (OrthoANI) and digital DNA–DNA hybridization (dDDH) analyses confirmed that strain MAP12T is distinctly separated from its closest neighbors (OrthoANI < 89 %; dDDH < 36%). Though several members of the genus Pseudomonas are well known for their aerobic BTEX degradation capability, this is the first report of a novel Pseudomonas species capable of degrading xylene under microaerobic conditions. By applying genome-resolved metagenomics, we were able to partially reconstruct the genome of strain MAP12T from metagenomics sequence data and showed that strain MAP12T was an abundant member of the xylene-degrading bacterial community under microaerobic conditions. Strain MAP12T contains ubiquinone 9 (Q9) as the major respiratory quinone and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine as major polar lipids. The major cellular fatty acids of strain MAP12T are summed feature 3 (C16:1ω6c and/or C16:1ω7c), C16:0 and summed feature 8 (C18:1ω6c and/or C18:1ω7c). The results of this polyphasic study support that strain MAP12T represents a novel species of the genus Pseudomonas, hence the name of Pseudomonas aromaticivorans sp. nov. is proposed for this strain considering its aromatic hydrocarbon degradation capability. The type strain is MAP12T (=LMG 32466, =NCAIM B.02668).

Abstract
The Moroccan coast is characterized by a diversity of climate, reflecting a great richness and diversity of fauna and flora. By this, marine microbiota plays a fundamental role in many biogeochemical processes, environmental modifications, and responses to temperature changes. To date, no exploration by high-throughput techniques has been carried out on the characterization of the Moroccan marine microbiota. The objective of this work is to study the diversity and metabolic functions of MMM from the Moroccan coast (Atlantic and Mediterranean) according to the water source (WS) and the type of climate (CT) using the approach high-throughput sequencing of the 16SrRNA gene. Four water samples of twelve sampling sites from the four major climates along the Moroccan coastline were collected, and prokaryotic DNA was extracted. V4 region of 16S rRNA gene was amplified, and the product PCR was sequenced by Illumina Miseq. The β-diversity and α-diversity indices were determined to assess the species richness and evenness. The obtained results were analyzed by Mothur and R software. A total of twenty-eight Bacterial phyla and twelve Archaea were identified from the samples. Proteobacteria, Bacteroidetes, and Cyanobacteria are the three key bacterial phyla, and the Archaeal phyla identified are: Euryarchaeota, Nanoarchaeaeota, Crenarchaeota, Hydrothermarchaeota, Asgardaeota, Diapherotrites, and Thaumarchaeota in the Moroccan coastline and the four climates studied. The whole phylum are involved in marine biogeochemical cycles, and through their functions they participate in the homeostasis of the ocean in the presence of pollutants or stressful biotic and abiotic factors. In conclusion, the obtained results reported sufficient deepness of sequencing to cover the majority of Archaeal and Bacterial genera in each site. We noticed a strong difference in microbiota diversity, abundance, and taxonomy inter- and intra-climates and water source without significant differences in function. To better explore this diversity, other omic approaches can be applied such as the metagenomic shotgun, and transcriptomic approaches allowing a better characterization of the Moroccan marine microbiota and to understand the mechanisms of its adaptation and its impacts in/on the ecosystem.

Abstract
A Kikuchi–Fujimoto-betegség (histiocytás nekrotizáló lymphadenitis) egy
autolimitált folyamat, melynek kiváltó tényezőihez soroljuk az
Epstein–Barr-vírust, a humán herpeszvírust, a HIV-et, a B19 parvovírust, a
paromyxovirusokat, a SARS-CoV-2-t, illetve a Toxoplasmát és a
Yersiniát. A pontos diagnózis felállításához
elengedhetetlen a nyirokcsomó-biopszia, melyet szövettani vizsgálat követ. Egy
45 éves nőbeteg igazolt SARS-CoV-2-fertőzést követően egyoldali nyaki
nyirokcsomó-megnagyobbodással, lázzal, rekedtséggel, illetve nyelési
nehezítettséggel érkezett ambulanciánkra. SARS-CoV-2-fertőzése a tünetek
megjelenése előtt 1 hónappal kettős pozitív (orrgarati) gyorsteszt formájában
került bizonyításra, melyet 2 hetes otthoni karantén követett. Felszabadító
teszt nem készült, az ambulanter vizsgálat előtt végzett COVID–19 orrgarati
gyorsteszt negatív eredményt produkált. A fizikális status felmérését osztályos
felvétel követte, melynek során intravénás antibiotikumterápia indult
(Augmentin, 3 × 1,2 g; Klion, 2 × 100 mg) szteroidterápiával párhuzamosan
(Solu-Medrol, 2 × 125 mg). A nyaki-mellkasi CT jobb oldali retropharyngealis
tályogot írt le, nyaki nyirokcsomó-megnagyobbodással párhuzamosan. Sürgős
tracheotomiát, illetve nyaki feltárást végeztünk nyirokcsomó-biopsziával
egybekötve. A feltárás során tályogra utaló jelet nem találtunk. A szövettani
vizsgálat nekrotizáló lymphadenitist igazolt. Annak ellenére, hogy a betegség
autolimitált, látható, hogy a fenti esetben a SARS-CoV-2-fertőzést követően
kialakuló nyaki lymphadenopathia életet veszélyeztető állapot okozott, mely
miatt légcsőmetszés, nyaki feltárás, illetve nyirokcsomó-biopszia volt szükséges
a beteg állapotának javulásáért és betegségének pontos tisztázásáért. A
kialakult szöveti exsudatum nyaki tályog képét utánozta a CT-felvételeken. Az
általunk felkeresett, nagyszámú szakirodalmi közleményben hasonló beavatkozás
nem került leírásra. A nyaki feltárás, a tracheotomia, illetve a nyaki
nyirokcsomóknak mint ,,trigger” zónáknak az eltávolítása jelen esetünkben a
teljes gyógyulást eredményezte. Fontos a SARS-CoV-2, illetve a
Kikuchi–Fujimoto-betegség korrelációjának további megerősítése, pontosabb
tisztázása. Orv Hetil. 2022; 163(27): 1061–1065.

Abstract
Introduction. Thymoma is the most common tumour of the anterior mediastinum. Video-Assisted Thoracic Surgery technique of thymoma resection is spreading world-wide, but the thoracoscopic method is still contentious in many ways. Authors evaluate the early and mid-term results of a 17 years period of VATS unilateral approach at 2 Hungarian thoracic surgical centers. Method. Depending on the anatomical situation of the thymoma, we performed thymectomy, or partial thymectomy (thymomectomy) for the Masaoka–Koga I–II–III stage thymoma from the right or left side through 2 or 3 intercostal ports. We managed the operations with ultrasonic dissector and electrocauter. By using international standards we evaluated perioperative morbidity, mid-term oncological results and clinical symptoms of myasthenia. Results. 23 of the 54 patients were man, 31 were woman, the average age was 58 (26–79) years, 23 of them had myasthenia. The conversion rate was 11,5% (7/61). The average operation time was 84 (39–150) minutes. The average hospitalisation time was 5.5 (3–19) days. The average size of the thymomas was 46 (18–90) mm. The histology resulted thymoma type A in 2 cases, AB in 19 cases, B1/2/3 in 11/11/1 cases, mixed B in 10 cases. The examination of the resection line was R0/1/2 in 42/11/1 cases. The Masaoka–Koga stages were: I (17), IIA (28), IIB (2), III (7). There was 25 thymomectomies, and 29 thymectomies. In seven cases there were extension of the operation to the pericardium (2), to the lung (2), to the phrenic nerve (6), and to innominate vein (1). The in-hospital mortality over 30 day was in 1 case (1.85%). The morbidity was 11/54 (20.4%). The average follow-up time was 62.56 (5–198) months. In the group with myasthenia the effectivity of the operation was 18/21 (85.7%), including complete remission of 5/21 (23.8%). Post-thymectomy myasthenia gravis developed in 2/31 cases (6.5%). The average 5 years survival was 100%, tumour-free 5 years survival was 96%. Conclusions. The higher proportion of the thymomectomy in the early results, higher conversion rate and lower R0 proportion might be in connection with the attitude of the surgeons, with the learning curve and with the limitations of the unilateral method. After a longer follow-up time late results may become more real and comparable. Instead of unilateral VATS technique we have changed to the subxyphoideal approach of VATS because of its better visualisation.

Abstract
We investigated the efficacy and safety of vemurafenib+cobimetinib (V+C) and dabrafenib+trametinib (D+T) based on real-life data. From 2015 and 2018 we have selected 118 BRAF-mutated metastatic melanoma patients, treated with V+C and D+T in our institute. We retrospectively analyzed the overall response rate (ORR), the progression-free survival (PFS), the overall survival (OS) and the adverse events of the therapies. The median follow-up time was 18 months (3-43) with V+C and 12 months (3-43) with D+T. The median PFS was 8 months in the V+C and 8.5 months in the D+T group. Median OS was 18 months in V+C group and 12 months with D+T. The ORR was revealed to be 82% in D+T group and 76% in V+C group. Each combination displayed a slightly different safety profile. In our retrospective analysis both BRAF-MEK inhibitor combination therapies showed favorable efficacy with a slightly different spectrum of toxicity profile.

Abstract
Since the introduction of next-generation sequencing, the frequency of germline pathogenic TP53 variants and the number of cases with unusual clinical presentations have been increasing. This has led to the expansion of the classical Li–Fraumeni syndrome concept to a wider cancer predisposition syndrome designated as the Li–Fraumeni spectrum. Here, we present a case with a malignant, metastatic perivascular epithelioid cell tumor (PEComa) of the thigh muscle and a sinonasal carcinoma harboring a novel TP53 germline splice mutation (NM_000546.5:c.97-2A>C). The classical presentation of LFS in the long-since deceased mother and the presence of a germline TP53 variant in the proband suggested a possible familial TP53-related condition. Complex pathological, molecular, and clinical genetic analyses (whole exome sequencing of germline variants, multigene panel sequencing of tumor DNA, Sanger validation, an in vitro functional test on splicing effect, 3D protein modeling, p53 immunohistochemistry, and pedigree analysis) were performed. The in vitro characterization of the splice mutation supported the pathogenic effect that resulted in exon skipping. A locus-specific loss of heterozygosity in the PEComa but not in the sinonasal carcinoma was identified, suggesting the causative role of the splice mutation in the PEComa pathogenesis, because we excluded known pathogenetic pathways characteristic to PEComas (TSC1/2, TFE3, RAD51B). However, the second hit affecting TP53 in the molecular pathogenesis of the sinonasal carcinoma was not identified. Although PEComa has been reported previously in two patients with Li–Fraumeni syndrome, to the best of our knowledge, this is the first report suggesting a relationship between the aberrant TP53 variant and PEComa.

Abstract
Two Gram-reaction-negative strains, designated as B13T and MA2-2, were isolated from two different aromatic hydrocarbon-degrading enrichment cultures and characterized using a polyphasic approach to determine their taxonomic position. The two strains had identical 16S rRNA gene sequences and were most closely related to
Pinisolibacter ravus
E9T (97.36 %) and
Siculibacillus lacustris
SA-279T (96.33 %). Cells were facultatively aerobic rods and motile with a single polar flagellum. The strains were able to degrade ethylbenzene as sole source of carbon and energy. The assembled genome of strain B13T had a total length of 4.91 Mb and the DNA G+C content was 68.8 mol%. The predominant fatty acids (>5 % of the total) of strains B13T and MA2-2 were C18 : 1
ω7c/C18 : 1
ω6c, C16 : 1
ω7c/C16 : 1
ω6c and C16 : 0. The major ubiquinone of strain B13T was Q10, while the major polar lipids were phosphatidyl-N-methylethanolamine, phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and a phospholipid. Based on phenotypic characteristics and phylogenetic data, it is concluded that strains B13T and MA2-2 are members of the genus
Pinisolibacter
and represent a novel species for which the name Pinisolibacter aquiterrae sp. nov. is proposed. The type strain of the species is strain B13T (=LMG 32346T=NCAIM B.02665T).

Abstract
In the present study, the prokaryotic community structure of the water of Lake Balaton was investigated at the littoral region of three different points (Tihany, Balatonmáriafürdő and Keszthely) by cultivation independent methods [next-generation sequencing (NGS), specific PCRs and microscopy cell counting] to check the hidden microbial diversity of the lake. The taxon-specific PCRs did not show pathogenic bacteria but at Keszthely and Máriafürdő sites extended spectrum beta-lactamase-producing microorganisms could be detected. The bacterial as well as archaeal diversity of the water was high even when many taxa are still uncultivable. Based on NGS, the bacterial communities were dominated by Proteobacteria, Bacteroidetes and Actinobacteria, while the most frequent Archaea belonged to Woesearchaeia (Nanoarchaeota). The ratio of the detected taxa differed among the samples. Three different types of phototrophic groups appeared: Cyanobacteria (oxygenic phototrophic organisms), Chloroflexi (anaerobic, organotrophic bacteria) and the aerobic, anoxic photoheterotrophic group (AAPs). Members of Firmicutes appeared only with low abundance, and Enterobacteriales (order within Proteobacteria) were present also only in low numbers in all samples.

Abstract
A Gram-reaction-negative halotolerant bacterial strain, designated Ka21T, was isolated from agricultural soil and characterised using a polyphasic approach to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, highest similarity was found with Sphingobacterium alkalisoli Y3L14T (96.72%). Cells were observed to be aerobic, non-motile rods. The isolate was found to be able to grow between 0 and 10% of NaCl concentration. The assembled genome of strain Ka21T has a total length of 5.2 Mb with a G + C content of 41.0 mol%. According to the genome analysis, Ka21T encodes several glycoside hydrolases that may play a role in the degradation of accumulated plant biomass in the soil. Based on phenotypic characteristics and phylogenetic analysis, it is concluded that strain Ka21T represents a novel species in the Sphingobacterium genus for which the name Sphingobacterium pedocola sp. nov. is proposed. The type strain of the species is strain Ka21T (= LMG 31575T = NCAIM B.02636T).

Abstract
AIMS Non-invasive and simultaneous recording of gastrointestinal (GI) activity during stress induction is still an unexplored field. In our previous investigation, the stress-induced alteration of the gastrointestinal tract was explored in rats. Our aims were to expand our previous rat experiment and to induce stress response in rats (Study 1) and humans (Study 2) to detect the GI tract activity, heart rate and body temperature. MATERIALS AND METHODS In the preclinical sample, acute stress was induced by immobilization in Sprague-Dawley rats (N = 10). Acute stress response was generated by the Trier Social Stress Test among healthy volunteers (N = 16). Detection of acute stress was measured by using smooth muscle electromyography, which recorded the myoelectric waves of the gastrointestinal tract (stomach, ileum and colon) simultaneously with heart rate and body temperature in rats and humans. KEY FINDINGS The myoelectric waves of the stomach, the cecum and the ileum increased during immobilization in rats, rising in parallel with heart rate and the dermal temperature of the abdominal surface. The same alterations were found during the stress period among humans, except in the case of the colon, where no change was detected. SIGNIFICANCE The crucial role of the GI tract in stress response was revealed by translating the outcome of basic research into human results. The similar GI alterations during stress in rats and humans underpin the robustness of our findings. In summary, our preliminary translational-based study can serve as an appropriate basis for further human studies.

Abstract
Three Gram-stain-negative, non-motile, oxidase- and catalase-positive, rod-shaped, black, facultative phototrophic bacterial strains, RG-N-1aT, DMA-N-7a and RA-N-9 were isolated from the water sample from Lake Fertő/Neusiedler See (Hungary). Phylogenetic analysis based on the 16S rRNA gene sequences revealed that the strains form a distinct linage within the family Rhodobacteraceae and their closest relatives are Tabrizicola piscis K13M18T (96.32%) followed by Cypionkella psychrotolerans PAMC 27389T (96.25%). The novel bacterial strains prefer alkaline environments and grow optimally at 23-33 °C in the presence of NaCl (1-2 w/v%). Bacteriochlorophyll a was detected. Cells contained exclusively ubiquinone Q-10. The major cellular fatty acids were C18 : 1ω7c, C19 : 1iso ω5c, C18 : 0 3-OH and C18 : 1ω7c 11-methyl. The polar lipid profile contains diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an unidentified phospholipid and four unidentified lipids. The assembled draft genome of RG-N-1aT had 33 contigs with N50 values 315 027 nt, 96× genome coverage, total length of 4 326 551 bp and a DNA G+C content of 64.9%. Genome-based calculations (genome-to-genome distance and DNA G+C percentage) and pairwise amino acid identity (AAI <73.5%) indicate that RG-N-1aT represents a novel genus. RG-N-1aT (=DSM 108317T=NCAIM B.02647T) is suggested as the type strain of a novel genus and species in the family Rhodobacteraceae, for which the name Fertoeibacter niger gen. nov., sp. nov. is proposed.

Abstract
A benzene, para- and meta-xylene-degrading Gram-stain-negative, aerobic, yellow-pigmented bacterium, designated as D2P1T, was isolated from a para-xylene-degrading enrichment culture. Phylogenetic analyses based on 16S rRNA genes showed that D2P1T shares a distinct phyletic lineage within the genus Hydrogenophaga and shows highest 16S rRNA gene sequence similarity to Hydrogenophaga taeniospiralis NBRC 102512T (99.2 %) and Hydrogenophaga palleronii NBRC 102513T (98.3 %). The draft genome sequence of D2P1T is 5.63 Mb long and the genomic DNA G+C content is 65.5 %. Orthologous average nucleotide identity (OrthoANI) and digital DNA-DNA hybridization (dDDH) analyses confirmed low genomic relatedness to its closest relatives (OrthoANI <86 %; dDDH <30 %). D2P1T contains ubiquinone 8 (Q-8) as the only respiratory quinone and phospholipid, phosphatidylglycerol, phosphatidylethanolamine, diphosphatidylglycerol as major polar lipids. The main whole-cell fatty acids of D2P1T are summed feature 3 (C16 : 1 ω7c/C16 : 1 ω6c), C16 : 0 and summed feature 8 (C18 : 1 ω7c/C18 : 1 ω6c). The polyphasic taxonomic results indicated that strain D2P1T represents a novel species of the genus Hydrogenophaga, for which the name Hydrogenophaga aromaticivorans sp. nov. is proposed. The type strain is D2P1T (=LMG 31780T=NCAIM B 02655T).

Abstract
There have been some relevant changes in the diagnosis and treatment of breast cancer to implement the updating of the 2016 recommendations made during the 3rd national consensus conference on the disease. Following a wide interdisciplinary consultation, the present recommendations have been finalized after their public discussion at the 4th Hungarian Breast Cancer Consensus Conference. The recommendations cover non-operative, intraoperative and postoperative diagnostics, the determination of prognostic and predictive markers and the content of the cytology and histology reports. Furthermore, it touches some special issues such as the current status of multigene molecular markers, the role of pathologists in clinical trials and prerequisites for their involvement, some relevant points about the future. The most important changes include the integration of the TNM 8th edition, the WHO classification of breast tumors 5th edition, the ASCO/CAP HER2 assessment guidelines from 2018, and the Yokohama terminology for cytology reporting; a more detailed text on tumor-infiltrating lymphocytes and size determination after neoadjuvant therapy and a broader discussion of molecular tests.

Abstract
In Hungary, which is famous for its thermal baths, according to the regulations, waters are investigated in hygienic aspects with standard cultivation methods. In the present study, two thermal baths were investigated (the well and three different pool waters in both) using cultivation methods, taxon-specific polymerase chain reactions (PCRs), multiplex PCRs and next-generation amplicon sequencing. Mainly members of the natural microbial community of the well waters and bacteria originating from the environment were detected but several opportunistic pathogenic taxa, e.g., Pseudomonas aeruginosa, P. stutzeri, Acinetobacter johnsoni, Acinetobacter baumanni, Moraxella osloensis, Microbacterium paraoxydans, Legionella spp., Stenotrophomonas maltophilia and Staphylococcus aureus were revealed by the applied methods. Pools with charging-unloading operation had higher microscopic cell counts, colony-forming unit (CFU) counts, number of cocci, P. aeruginosa and S. aureus compared to the recirculation systems. Bacteria originating from human sources (e.g., skin) were identified in the pool waters with less than 1% relative abundance, and their presence was sporadic in the pools. Comparing the microbiological quality of the pools based on the first sampling time and the following four months' period it was revealed that recirculation operation type has better water quality than the charging-unloading pool operation from a hygienic point of view.

Abstract
Little is known about the detailed community composition of heterotrophic bacterioplankton in macrophyte-dominated littoral systems, where a considerable amount of dissolved organic carbon originates from aquatic macrophytes instead of phytoplankton. The aim of the present study was to reveal the effect of macrophytes on the microbial community and to elucidate their role in a macrophyte-dominated shallow soda lake, which can be characterised by a mosaic of open waters and reed marsh. Therefore, 16S rRNA gene amplicon sequencing, the most probable number method, cultivation of bacterial strains, EcoPlate and cultivation-based substrate utilisation techniques were applied. Differences in the structures of microbial communities were detected between the water and the sediment samples and between vegetated and unvegetated water samples. Planktonic bacterial communities of an inner pond and a reed-covered area showed significant similarities to each other. Woesearchaeia was the dominant archaeal taxon in the water samples, while Bathyarchaeia, 'Marine Benthic Group D' and 'DHVEG-1' were abundant in the sediment samples. The most probable number of heterotrophic bacteria was lower in the open water than in the reed-associated areas. The vast majority (83%) of the isolated bacterial strains from the water samples of the reed-covered area were able to grow on a medium containing reed extract as the sole source of carbon.

Abstract
Cupriavidus sp. are model organisms for heavy metal(loid) resistance and aromatic compound's degradation studies and these characteristics make them a perfect candidate for biotechnological purposes. Bacterial strain S14E4C (identified as Cupriavidus campinensis) was isolated from a playground by enrichment method in a 0.25 mM containing medium. The analysis revealed that this bacterium is able to tolerate high concentrations of heavy metal(loid)s: Cd up to 19.5 mM, Pb to 9 mM, Hg to 5.5 mM and As to 2 mM in heavy metal(loid) salt containing nutrient medium. The whole genome data and analysis of the type strain of C. campinensis CCUG:44526T have not been available so far, thus here we present the genome sequencing results of strain S14E4C of the same species. Analysis was carried out to identify possible mechanisms for the heavy metal resistance and to map the genetic data of C. campinensis. The annotation pipelines revealed that the total genome of strain S14E4C is 6,375,175 bp length with a GC content of 66.3% and contains 2 plasmids with 295,460 bp (GC content 59.9%) and 50,483 bp (GC content 63%). In total 4460 coding sequences were assigned to known functions and 1508 to hypothetical proteins. Analysis proved that strain S14E4C is having gene clusters such as czc, mer, cus, chr, ars to encode various heavy metal resistance mechanisms that play an important role to survive in extreme environments.

Results of phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain forms a distinct linage within the family
Verrucomicrobiaceae
of the phylum
Verrucomicrobia
, and its closest relatives are
Verrucomicrobium spinosum
DSM 4136T (94.38 %) and
Roseimicrobium gellanilyticum
DC2a-G7T (91.55 %). The novel bacterial strain prefers a weak alkaline environment and grows optimally between 22–28 °C in the absence of NaCl. The major isoprenoid quinones are MK-10, MK-11, MK-12 and MK-9. The major cellular fatty acids are anteiso-C15 : 0, C16 : 0, C16 : 1ω5c and iso-C14 : 0. The polar lipid profile contains phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids and four unidentified glycolipids.

Abstract
Background Based on its mechanism of action, PARP inhibitor therapy is expected to benefit mainly tumor cases with homologous recombination deficiency (HRD). Therefore, identification of tumor types with increased HRD is important for the optimal use of this class of therapeutic agents. HRD levels can be estimated using various mutational signatures from next generation sequencing data and we used this approach to determine whether breast cancer brain metastases show altered levels of HRD scores relative to their corresponding primary tumor. Patients and methods We used a previously published next generation sequencing dataset of 21 matched primary breast cancer/brain metastasis pairs to derive the various mutational signatures/HRD scores strongly associated with HRD. We also carried out the myChoice HRD analysis on an independent cohort of 17 breast cancer patients with matched primary/brain metastasis pairs. Results All of the mutational signatures indicative of HRD showed a significant increase in the brain metastases relative to their matched primary tumor in the previously published whole exome sequencing dataset. In the independent validation cohort, the myChoice HRD assay showed an increased level in 87.5% of the brain metastases relative to the primary tumor, with 56% of brain metastases being HRD positive according to the myChoice criteria. Conclusions The consistent observation that brain metastases of breast cancer tend to have higher HRD measures may raise the possibility that brain metastases may be more sensitive to PARP inhibitor treatment. This observation warrants further investigation to assess whether this increase is common to other metastatic sites as well, and whether clinical trials should adjust their strategy in the application of HRD measures for the prioritization of patients for PARP inhibitor therapy.

Abstract
Background: Chemotherapeutic agents are often mutagenic. Induction of mutation associated neo-epitopes is one of the mechanisms by which chemotherapy is thought to increase the number of tumor-infiltrating lymphocytes. It is not known, however, whether treatment with various chemotherapeutic agents with different mutagenic capacity induce a significantly different number of stromal tumor-infiltrating lymphocytes (StrTIL) in residual cancer.Methods: One hundred and twenty breast carcinoma cases with residual disease that were treated with one of three types of pre-operative chemotherapy regimens were selected for the study. The percentage of StrTIL was evaluated in pretreatment core biopsies (pre-StrTIL) and post-treatment surgical tumor samples (post-StrTIL). TIL changes (ΔStrTIL) were calculated from the difference between post-StrTIL and pre-StrTIL.Results: When analyzing the pre-StrTIL and post-StrTIL among the three treatment groups, we detected significant StrTIL increase independently of the treatment applied. Based on distant metastases-free survival analysis, both post-StrTIL and ΔStrTIL was found to be independent prognostic factor in HR negative cases. Conclusions: Significant increase of StrTIL in the residual disease was observed in patients treated with the highly (platinum), moderately (cyclophosphamide) and marginally mutagenic chemotherapeutic agents (taxane, anthracycline). Increase in StrTIL in residual cancer compared to pretreatment tumor tissue is associated with improved distant metastasis-free survival in cases with HR negative breast carcinoma.
