AIMS: Sinonasal adenosquamous carcinoma (ASC) is a rare tumour classified as a variant of squamous cell carcinoma, exhibiting both squamous and glandular differentiation. ASC has a poorer prognosis compared to sinonasal mucoepidermoid carcinoma (MEC), another uncommon tumour in this region. ASC is believed to originate from metaplastic squamous epithelium, though it may also arise from respiratory epithelium in respiratory epithelial adenomatoid hamartoma (REAH) or seromucinous glands in seromucinous hamartoma (SH). METHODS AND RESULTS: Five cases of sinonasal ASC were retrieved from our registry. Initially, they were classified as sinonasal MEC (n = 3), ASC (n = 2), and carcinoma ex REAH (n = 1). All cases showed adenosquamous malignant proliferation beneath the surface respiratory epithelium with occasional squamous metaplasia, except for one case that showed dysplasia. The respiratory epithelium exhibited an inverted growth pattern consistent with REAH/SH, and displayed atypical sinonasal glands (ASGSH) arising within seromucinous hamartoma. Next-generation sequencing (NGS) revealed multiple pathogenic mutations in two cases, and in case 4 GGA2::PRKCB and EYA2::SERINC3 gene fusions. One case was positive for high-risk HPV. None of the cases exhibited CRTC1/3::MAML2 gene fusion. CONCLUSION: The connection between ASGSH and ASC has not been described in the literature. There is a growing need for additional studies on the morphological, immunohistochemical, and genetic aspects of these tumours. SH/REAH may serve as precursor lesions in the progression of atypical sinonasal glands to malignancy, and their role in tumour development deserves further investigation.

Pomocí molekulárně genetických metod lze prokázat infekční organismy virového, bakteriálního a houbového původu, stejně jako protozoa a parazitické červy. Molekulární metody detekují specifické úseky v sekvencích nukleových kyselin infekčních agens, a není tedy nutné zachování viability hledaných mikroorganismů. Proto je možné použít tyto metody i pro přímý průkaz infekčního agens z fixované tkáně, nejčastějšího dostupného materiálu v patologii. Tento krátký přehledový článek vychází z více než dvacetiletého fungování molekulárně mikrobiologického úseku v rámci patologie a naším cílem je přiblížit možnosti molekulárně genetické detekce infekčních organismů pro patologickou diagnostiku.

Using molecular methods, infectious organisms of viral, bacterial and fungal origin, as well as protozoa and helminths, can be detected. Molecular methods detect specific segments in the nucleic acid sequences of infectious agents and therefore do not require the maintenance of viability of the microorganisms of interest. Therefore, these methods can also be used for direct detection of infectious agents from fixed tissue, the most commonly available material in pathology. This short review article is based on more than 20 years of molecular microbiology within pathology and our aim is to present the possibilities of molecular detection of infectious organisms for pathological diagnosis.

BACKGROUND: Job satisfaction is a key factor for the successful transition of newly graduated nurses (NGNs) and for retaining NGNs in their workplaces. However, there is limited evidence of the relationship between satisfaction regarding the nursing education program and NGNs' job satisfaction in the first year after graduation. Therefore, this study aims to examine the association of the nursing education related factors and NGNs' job satisfaction. METHODS: A cross-sectional study design with the utilization of data collected from the same respondents one year earlier as educational factors was applied. The data were collected from NGNs (n = 557) in 10 European countries using an electronic survey between February 2019 and September 2020, and analyzed in detail for four countries (n = 417). Job satisfaction was measured with three questions: satisfaction with current job, quality of care in the workplace, and nursing profession. Nursing education related factors were satisfaction with nursing education program, level of study achievements, nursing as the 1st study choice, intention to stay in nursing, and generic nursing competence. The data were analyzed statistically using logistic regression. RESULTS: Most of the NGNs in the 10 countries were satisfied with their current job (88.3%), the quality of care (86.4%) and nursing profession (83.8%). Finnish, German, Lithuanian and Spanish NGNs' satisfaction with the nursing education program at graduation was statistically significantly associated with their job satisfaction, i.e., satisfaction with their current job, the quality of care, and the nursing profession. Moreover, NGNs who had fairly often or very often intention to stay in nursing at graduation were more satisfied with their current job, with the quality of care, and with the nursing profession compared with NGNs who had never or fairly seldom intention to stay in nursing at graduation. CONCLUSIONS: Nursing education plays a significant role in NGNs' job satisfaction one year after graduation, indicating the importance to start career planning already during nursing education. Both nursing education providers and healthcare organizations could plan in close collaboration a transition program for NGNs to ease the transition phase and thus increase the NGNs' job satisfaction and ultimately the high-quality care of the patients.

Metylační umlčení některých buněčných genů je známkou progrese karcinogeneze a proto testy, které metylaci detekují, by mohly být využívány v diagnostice či „stagingu“ maligních onemocnění. V diagnostice dlaždicobuněčných karcinomů děložního hrdla (DH), které jsou téměř ve 100 % způsobeny dlouhodobou infekcí vysoce rizikovými lidskými papilomaviry (HR-HPV), je metylační umlčení určitých buněčných genů vysoce specifickým markerem pokročilé dysplastické léze a zřejmě vzniká důsledkem aberantní aktivace metyltransferázy DNMT1 virovými onkoproteiny E6 a E7. Metylační test provedený ze vzorku cervikovaginální cytologie umožňuje zvýšit výpovědní hodnotu tohoto neinvazivního vyšetření a selektovat pacientky s biologicky závažnou dlaždicobuněčnou lézí pro následné vyšetření. Pomocí cytologického vyšetření lze odhalit také méně časté anogenitální malignity, které jsou indukované HR-HPV v nižší míře – žlázové léze různého původu, nejčastěji adenokarcinomy DH a endometria a anální karcinom. Cílem naší pilotní studie bylo ohodnotit přínos metylačního testu pro diagnostiku těchto malignit na souboru 50 tekutých cervikovaginálních cytologií s nálezem žlázové léze a 74 tekutých análních cytologií HIV-pozitivních homosexuálů, kteří jsou ve vysokém riziku vzniku karcinomu anu.

Methylation silencing of certain cellular genes is a sign of carcinogenesis progression and therefore tests that detect methylation could be used in the diagnosis or staging of malignant diseases. In the diagnosis of squamous cell carcinomas of the cervix which are almost 100% caused by long-term infection with highrisk human papillomavirus (HR-HPV), methylation silencing of certain cellular genes is a highly specific marker of advanced dysplastic lesions and appears to result from aberrant activation of the methyltransferase DNMT1 by viral oncoproteins E6 and E7. A methylation test performed on a cervicovaginal cytology specimen allows to increase the diagnostic value of this non-invasive test and to select patients with severe squamous cell lesions for follow-up. Other less frequent anogenital malignancies that are induced by HR-HPV to a lesser extent can also be detected by cytological examination - glandular lesions of various origins, most commonly cervical and endometrial adenocarcinomas and anal carcinoma. The aim of our pilot study was to evaluate the utility of a methylation test for the diagnosis of these malignancies in a cohort of 50 liquid-based cervicovaginal cytologies with glandular lesion and 74 liquid-based anal cytologies from HIV-positive men having sex with men who are at high risk for anal cancer development.

SIGNIFICANCE STATEMENT: Although cytomegalovirus (CMV) infection is an important factor in the pathogenesis of kidney allograft rejection, previous studies have not determined the optimal CMV prevention strategy to avoid indirect effects of the virus. In this randomized trial involving 140 kidney transplant recipients, incidence of acute rejection at 12 months was not lower with valganciclovir prophylaxis (for at least 3 months) compared with preemptive therapy initiated after detection of CMV DNA in whole blood. However, prophylaxis was associated with a lower risk of subclinical rejection at 3 months. Although both regimens were effective in preventing CMV disease, the incidence of CMV DNAemia (including episodes with higher viral loads) was significantly higher with preemptive therapy. Further research with long-term follow-up is warranted to better compare the two approaches. BACKGROUND: The optimal regimen for preventing cytomegalovirus (CMV) infection in kidney transplant recipients, primarily in reducing indirect CMV effects, has not been defined. METHODS: This open-label, single-center, randomized clinical trial of valganciclovir prophylaxis versus preemptive therapy included kidney transplant recipients recruited between June 2013 and May 2018. After excluding CMV-seronegative recipients with transplants from seronegative donors, we randomized 140 participants 1:1 to receive valganciclovir prophylaxis (900 mg, daily for 3 or 6 months for CMV-seronegative recipients who received a kidney from a CMV-seropositive donor) or preemptive therapy (valganciclovir, 900 mg, twice daily) that was initiated after detection of CMV DNA in whole blood (≥1000 IU/ml) and stopped after two consecutive negative tests (preemptive therapy patients received weekly CMV PCR tests for 4 months). The primary outcome was the incidence of biopsy-confirmed acute rejection at 12 months. Key secondary outcomes included subclinical rejection, CMV disease and DNAemia, and neutropenia. RESULTS: The incidence of acute rejection was lower with valganciclovir prophylaxis than with preemptive therapy (13%, 9/70 versus 23%, 16/70), but the difference was not statistically significant. Subclinical rejection at 3 months was lower in the prophylaxis group (13% versus 29%, P = 0.027). Both regimens prevented CMV disease (in 4% of patients in both groups). Compared with prophylaxis, preemptive therapy resulted in significantly higher rates of CMV DNAemia (44% versus 75%, P < 0.001) and a higher proportion of patients experiencing episodes with higher viral load (≥2000 IU/ml), but significantly lower valganciclovir exposure and neutropenia. CONCLUSION: Among kidney transplant recipients, the use of valganciclovir prophylaxis did not result in a significantly lower incidence of acute rejection compared with the use of preemptive therapy.

Anální karcinom (AK) patří mezi malignity se stoupající incidencí, hlavně ve specifických populacích mužů, kteří mají sex s muži (MSM), a HIV pozitivních pacientů. V těchto skupinách je incidence až 131 případů na 100 000 obyvatel. Vzhledem k rostoucímu počtu HIV pozitivních pacientů nejen v České Republice, zejména u MSM, je včasná diagnostika prekanceróz základním předpokladem v boji s tímto onemocněním. AK je svou etiologií a biologickým chováním velmi podobný karcinomu děložního hrdla, proto i vyšetřovací a screeningové postupy jsou téměř identické. Základem je klinické vyšetření a cytologická analýza stěru sliznice. Anální cytologie nepatří mezi vysoce senzitivní ani specifická vyšetření. Naopak metylace DNA tumor-supresorových genů se takovou metodou být zdá, s již potvrzenou efektivitou ve screeningu karcinomu děložního hrdla. Tento výzkum by měl ověřit metylaci DNA jako novou diagnostickou a potencionální screeningovou metodu pro AK a porovnat její senzitivitu a specifitu s již zavedenými vyšetřovacími metodami u imunokompetentních i imunosuprimovaných pacientů.; Anal cancer is one of the malignancies with the rising incidence, especially at specific populations of men who have sex with men (MSM) and HIV positive patients. In these groups incidence reaches up 131 cases per 100 thousand inhabitants. Due to steeply increasing number of HIV positive patients in the Czech Republic (CR), whose vast majority belongs to MSM, early diagnosis of precancerous lesions is an essential prerequisite in the fight against this disease. Anal cancer is in its etiology and biological behavior very similar to cervical cancer, therefore the investigative and screening procedures are virtually identical. Currently used cytology in the anal area is not among the highly sensitive nor specific methods of investigation. DNA methylation appears to be a new method having already confirmed efficiency in screening of cervical cancer. This research should therefore validate DNA methylation as a potential new diagnostic and screening method for anal cancer and compare its sensitivity and specificity with established screening methods in immunocompetent and immunosuppress...

BACKGROUND: HIV-positive men who have sex with men (MSM) are more likely to experience human papillomavirus (HPV) infection. The persistent HPV infection is the major factor in the development of anal and oropharyngeal neoplasms. Data on the prevalence of anal and oral HPV in MSM are almost absent from the countries of Central and Eastern Europe. We conducted a cross-sectional study focused on the prevalence of oral and anal HPV infections and the relationship between current anal and oral HPV intrapersonal infection in a Czech population of predominantly HIV-positive MSM. METHODS: Oral gargle and anal swab samples from 205 predominantly HIV-positive MSM from the Czech Republic were analysed for HPV infection using PCR. Selected sociodemographic and clinical data were correlated with HPV detection using generalized linear models and multivariate analysis. RESULTS: HPV infection was detected in 183 (96.8%) anal and 48 (23.6%) oral samples. The most common type of HR-HPV was HPV16 in both anal (25.4%) and oral (2.5%) samples. Multiple anal HPV infections and the presence of vaccine-targeted HR-HPV types were significantly correlated with abnormal anal cytology and HIV status. CONCLUSION: The prevalence of anal HPV infection in Czech predominantly HIV-positive MSM ranks among the highest reported, while oral HPV prevalence is consistent with MSM populations. Minimal overlap of oral and anal HPV types within a patient was observed.

Anální karcinom je nádor s nízkou prevalencí, ale vysokou morbiditou. Díky vzácnosti tohoto nádoru proto nebylo donedávna ani uvažováno o jeho screeningu. V posledních dekádách však dochází k nárůstu počtu případů hlavně v populaci HIV pozitivních mužů majících sex s muži. Vzhledem k tomu, že většina případů análního karcinomu jsou dlaždicobuněčné karcinomy asociované s infekcí lidskými papilomaviry (HPV), máme obdobně jako v případě karcinomu děložního hrdla i v případě análního karcinomu možnost sekundární prevence pomocí vhodného screeningu. Základem současných screeningových vyšetření je digitální anorektální vyšetření, cytologické vyšetření a anoskopie. Včasné zachycení léčitelných forem je důležité i vzhledem k tomu, že díky kulturním změnám a prevalenci rizikových faktorů lze v budoucnu předpokládat nadále zvyšování incidence tohoto nádoru. Ke zvýšení efektivity screeningu je však nutná taktéž edukace a motivace rizikových skupin pacientů, hlavně rozšiřováním povědomí o análním karcinomu a roli rizikového sexuálního chování a HPV infekce.

Anal cancer is a tumour with a low prevalence but high morbidity. Due to the rarity of this tumour, therefore, its screening has not been considered until recently. However, in recent decades there has been an increase in the number of cases, especially in the population of HIV-positive men having sex with men. Since the most cases of anal cancer are squamous cell carcinomas associated with human papillomavirus (HPV) infection, as in the case of cervical cancer, there is the possibility of secondary prevention through appropriate screening. The basis of current screening examinations are digital anorectal examination, cytological examination and anoscopy. Early detection of treatable forms is important, also based on the fact that due to cultural changes and the prevalence of risk factors, an increase in the incidence of this tumour can be expected. However, education and motivation of at-risk groups of patients are necessary to increase the effectiveness of the screening, mainly by raising awareness of anal cancer and the role of risky sexual behavior and HPV infection.

New nurses are needed in healthcare. To meet the role expectations of a registered nurse, nursing students must feel empowered at graduation. However, there are only a few studies focusing on nursing students' empowerment. This study aims to describe and analyze graduating nursing students' level of empowerment in six European countries and potential related factors. A comparative and cross-sectional study was performed in the Czech Republic, Finland, Italy, Portugal, Slovakia, and Spain with graduating nursing students (n = 1746) using the Essential Elements of Nurse Empowerment scale. Potentially related factors included age, gender, a previous degree in health care, work experience in health care, graduation to first-choice profession, intention to leave the nursing profession, level of study achievements, satisfaction with the current nursing programme, clinical practicums, theoretical education, and generic competence measured with the Nurse Competence Scale. The data were analysed statistically. Graduating nursing students' self-assessed level of empowerment was moderate, with statistical differences between countries. Those with high empowerment had no intention to leave the nursing profession, had a higher level of study achievements, and a higher self-assessed generic competence level. The results suggest that empowerment needs to be enhanced during nursing education. Further research is needed to understand the development of empowerment during the early years of a nursing career.
