Cytoplasmic expression of ß-catenin is an independent predictor of progression of conventional renal cell carcinoma: a simple immunostaining score.

AIMS: The aims of this study were to investigate the potential of ß-catenin as a biomarker for predicting cancer-specific survival, and to find a reproducible mode of evaluation of immunohistochemistry. METHODS AND RESULTS: ß-Catenin expression was analysed by immunohistochemistry in a cohort of 488 patients with conventional renal cell carcinoma (RCC) operated on between 2000 and 2010. The association between ß-catenin expression and cancer-specific survival was assessed with univariate and multivariate Cox regression models in relation to conventional clinical pathological prognostic factors, and by Kaplan-Meier survival analysis with the log rank test. The univariate Cox regression model revealed an association of cytoplasmic ß-catenin positivity and pathological variables with cancer-specific death. The multivariate Cox regression model analysis of tumours without metastatic disease at the first presentation identified the T-classification (P < 0.001) and cytoplasmic ß-catenin positivity as risk factors for postoperative tumour progression. Specifically, cytoplasmic ß-catenin expression was an independent factor indicating an unfavourable prognosis, with a four-fold higher risk of cancer-specific death (relative risk 4.017; 95% confidence interval 2.489-6.482; P < 0.001). The median survival time for patients with tumours showing cytoplasmic accumulation of ß-catenin was 48 months, whereas the overall survival time was 166 months. CONCLUSIONS: Cytoplasmic ß-catenin expression is an independent prognostic factor for conventional RCC, and may help to identify patients with a high risk of cancer-specific death and to direct optimized active surveillance or adjuvant therapy.

The Impact of Qualification and Hospice Education on Staff Attitudes during Palliative Care in Pediatric Oncology Wards-A National Survey.

BACKGROUND: Our knowledge about the attitudes of healthcare staff to palliative care in pediatric oncology is scarce. We aimed to assess their perceptions of palliative care in Hungary and find answers to the question of how to provide good palliative care for children. METHOD: Physicians (n = 30) and nurses (n = 43) working in the field of pediatric oncology (12 of them specialized in hospice care) were interviewed. Palliative care practice (communication, integration of palliative care, professionals' feelings and attitudes, and opportunities for improvement) was assessed by semi-structured interviews evaluated in a mixed quantitative and qualitative way by narrative categorical content analysis and thematic analysis. RESULTS: All providers displayed high negative emotions, positive evaluations, and used many active verbs. Nurses showed higher levels of denial, more self-references, and were more likely to highlight loss. Physicians emphasized the importance of communication regarding adequate or inadequate palliative care. Hospice specialists showed a higher passive verb rate, a lower self-reference, a lower need for psychological support, and a greater emphasis on teamwork and professional aspects. CONCLUSION: Our results show that nurses are more emotionally stressed than doctors in palliative care in pediatric oncology. To our knowledge, a study comparing doctors and nurses in this field has yet to be carried out. Our results suggest that pediatric oncological staff can positively evaluate a child's palliative care despite the emotional strain. Regarding hospices, professional practice in palliative care may be a protective factor in reducing emotional distress and achieving professional well-being.

Body Mass Index during Gluten-Free Diet in Patients with Celiac Disease.

The association of clinical variables with body mass index (BMI) and changes experienced during a gluten-free diet (GFD) in celiac disease (CD) is not well established. In this retrospective cohort study, we aimed to investigate factors aligned with baseline and a follow-up regarding BMI in CD cases diagnosed at the University of Pécs (Hungary). Data were collected regarding gender, age, clinical presentation, histology, serology, extraintestinal manifestations, and BMI upon diagnosis and during follow-up. To compare variables with baseline BMI and BMI changes in short-, intermediate-, and long-term periods, we applied univariate analyses. A total of 192 CD patients were included. Males had significantly higher mean BMI when compared with females at diagnosis (22.9 ± 4.1 vs. 21.4 ± 4.3 kg/m2, p = 0.041) and during follow-up (p = 0.031, p = 0.029, and p = 0.033 for short-, intermediate-, and long-term follow-ups, respectively). Non-classical CD patients experienced higher mean BMI at diagnosis (22.9 ± 4.0 vs. 20.7 ± 4.4 kg/m2, p < 0.001) and following long-term follow-up (24.5 ± 3.2 vs. 22.6 ± 3.4 kg/m2, p = 0.039) than classical patients. In conclusion, although the mean BMI remained in the normal range, it increased significantly during follow-up, even at the short-term follow-up. This change was characteristic for non-classical cases and males on the long-term follow-ups.

Higher Availability of Long-Chain Monounsaturated Fatty Acids in Preterm than in Full-Term Human Milk.

While the role of n-3 and n-6 long-chain polyunsaturated fatty acids (LCPUFAs) in the maturation of the infantile nervous system is extensively studied and relatively well-characterized, data on the potential developmental importance of the n-9 long-chain monounsaturated fatty acid (LCMUFA), nervonic acid (NA, C24:1n-9) are scarce and ambiguous. Therefore, the aim of the present study was to reanalyze our available data on the contribution of NA and its LCMUFA precursors, gondoic acid (C20:1n-9) and erucic acid (EA, C22:1n-9) to the fatty acid composition of human milk (HM) during the first month of lactation in mothers of both preterm (PT) and full-term (FT) infants. HM samples were obtained daily during the first week of lactation, and then on the 14th, 21st, and 28th days. Values of the LCMUFAs, C20:1n-9, EA, and NA were significantly higher in colostrum than in transient and mature HM. Consequently, there were highly significant inverse associations between LCMUFA values and the duration of lactation. Moreover, C20:1n-9, EA, and NA values were monotonously, considerably, and at many timepoints significantly higher in PT than in FT HM samples. By the 28th day of lactation, summarized LCMUFA values in PT HM samples declined to the level measured in FT HM samples on the first day of lactation; however, EA and NA values were still significantly higher in PT than in FT HM on the 28th day. Significantly higher availability of LCMUFAs in PT than in FT HM underpins the potential biological role of this hitherto somewhat neglected group of fatty acids.

Associations Between Temporomandibular Pain and Biobehavioral Variables in Dental Students in Response to an External Stressor.

AIMS: To assess changes in temporomandibular disorder (TMD) pain and multiple biobehavioral variables relevant to TMDs in response to an external stressor. METHODS: Self-reported data using online DC/TMD questionnaires were collected from volunteer dentistry graduate students. Data collection was performed on two occasions: during a non-exam period of the semester and during the subsequent exam period. Changes in the proportion of students with pain, differences in pain grade, and severity of biobehavioral status were measured and compared over the two periods. The association between severity of non-exam-period biobehavioral status and pain presence was also tested to assess whether biobehavioral variables can predict pain occurrence or persistence. Chi-square test, Wilcoxon signed-rank test, ANOVA, and Kruskal-Wallis tests were used for data analysis. P < .05 was considered significant. RESULTS: Of the 213 enrolled students, 102 remained after data reduction. In the non-exam period, the proportion of individuals with pain was 24.5%; in the exam period, the proportion was 54.9%, and more students had a higher pain grade. The severity of all biobehavioral variables was higher in the exam period, but there was no association between changes in the presence of pain and changes in biobehavioral variables. Higher anxiety and parafunction levels were found in those who reported pain on both occasions. CONCLUSION: Exam periods initiate readily measurable changes in the psychologic status of many students, as well as alterations in their temporomandibular pain. Higher levels of anxiety and oral behaviors during non-exam periods seem to be predictors for persisting pain.

Cognitive functioning and clinical characteristics of children with non-syndromic orofacial clefts: A case-control study.

Introduction: The higher rate of neuropsychiatric disorders in individuals with non-syndromic orofacial clefts has been well documented by previous studies. Our goal was to identify children with non-syndromic orofacial clefts that are at risk for abnormal neurodevelopment by assessing their developmental history and present cognitive functioning. Materials and methods: A single-center, case-controlled study was carried out at the Department of Pediatrics of the University of Pécs in Hungary. The study consisted of three phases including questionnaires to collect retrospective clinical data and psychometric tools to assess IQ and executive functioning. Results: Forty children with non-syndromic oral clefts and 44 age-matched controls participated in the study. Apgar score at 5 min was lower for the cleft group, in addition to delays observed for potty-training and speech development. Psychiatric disorders were more common in the cleft group (15%) than in controls (4.5%), although not statistically significant with small effect size. The cleft group scored lower on the Continuous Performance Test. Subgroup analysis revealed significant associations between higher parental socio-economic status, academic, and cognitive performance in children with non-syndromic orofacial clefts. Analyzes additionally revealed significant associations between early speech and language interventions and higher scores on the Verbal Comprehension Index of the WISC-IV in these children. Discussion: Children with non-syndromic orofacial clefts seem to be at risk for deficits involving the attention domain of the executive system. These children additionally present with difficulties that affect cognitive and speech development. Children with non-syndromic orofacial clefts show significant skill development and present with similar cognitive strengths as their peers. Longitudinal studies with larger sample sizes are needed to provide more conclusive evidence on cognitive deficits in children with non-syndromic orofacial clefts at risk for neurodevelopmental difficulties.

High Prevalence of Non-Vaccinated Oncogenic Human Papillomavirus Genotypes in High-Grade Squamous Intraepithelial Lesions of the Cervix: Thought-Provoking Results of a Detailed HPV Genotype Analysis.

Identification of HPV infection is usually performed on cytological specimens, despite the often transient virus types. HPV profile analysis of pathologically confirmed lesions can also be performed on formalin-fixed paraffin-embedded (FFPE) cone samples and should be taken as standard during follow-up. We compared HPV profiles of cytological and FFPE specimens of women diagnosed with HSIL. Archived PAP smears and FFPE cones from 49 patients were processed. For genotyping, the HPV Direct Flow CHIP test was used. All samples were positive. HPV profile agreement of the two sample types was 84.16-100%. Mono-infections occurred in 12.24% and 61.22% in PAP smears and FFPE specimens, respectively; while multi-infections were detected in 87.76% and 38.78%, respectively. The most abundant genotypes were HPVs 16, 31, and 51/33. Of all infections, 56.25% and 64.93% were caused by nonavalent vaccinated type (VT) HPVs; while 50.69% and 38.96% belonged to non-nonavalent VT HPVs, in PAP smears and FFPE specimens, respectively. Our results confirmed the importance of HPV genotyping of FFPE cone samples. We also confirmed a remarkable presence of non-vaccinated HPV types in HSIL cases indicating the importance of vaccine development.

Nitrones are able to release nitric oxide in aqueous environment under hydroxyl free radical attack.

Importance of a nitric oxide donor that can act as a spin trap might bring some new therapeutic possibilities regarding the treatment of ischemic diseases by reducing the intensity of free radical produced reperfusion lesions. These substances might be also used as a new type of photo protectors since they can absorb UV radiation, capture free radicals formed by interaction of UV radiation with tissue constituents, and tanning of the skin will be permitted due to nitric oxide release. The purpose of this work was to measure the ability of nitrones to release nitric oxide and how different factors (temperature, nitrone concentration, and free radicals) influence the releasing ability. Mostly, indirect determination of nitric oxide was carried out, by measuring nitrite and nitrate amounts (as decomposition products of nitric oxide), all nitrones proved to release significant amounts of nitric oxide. Nitrite measurements were made based on an HPLC-VIS method that uses pre-column derivatization of nitrite by forming an azo dye (limit of quantification: 5ng/ml). No good correlation was found between the amount of nitric oxide and temperature for most studied nitrones but between the formation of nitric oxide and nitrone concentration an asymptotic correlation was found. Fenton reagent also yielded formation of nitric oxide from nitrones and formed amounts were not different from those recorded for UV irradiation. Most of the nitrones effectively released about 0.5% of the maximum amount of nitric oxide that is chemically possible and estimated concentrations of 0.1µM were present in the solutions during decomposition.

Prevalence and correlation of severe early childhood caries among preschool children in Pécs / A súlyos korai gyermekkori fogszuvasodás elofordulása és összefüggései pécsi bölcsodések között.

Összefoglaló. Bevezetés és célkituzés: A 3 év alatti korcsoportban a súlyos kisgyermekkori fogszuvasodás (S-ECC) gyakoriságának vizsgálata és a kisgyermekes szülok szájegészséggel kapcsolatos ismereteinek felmérése. Módszer: Háromszázhatvankét, 36 hónapos vagy annál fiatalabb gyermek (átlagéletkor: 28,49 ± 5,25 hónap) fogászati szurovizsgálatát végeztük el, és szüleik számára önkéntesen kitöltheto kérdoívet állítottunk össze. A 306 kitöltött kérdoív eredményét a gyermekek fogászati statusával egyénenként összevetve statisztikai analízist végeztünk. Eredmények: A gyermekek fogászati szurésekor 15,46% volt a cariesprevalencia: df-t-index = 0,685 ± 2,20; az általunk javasolt, az elotört fogak számával módosított df-t-index = 0,758 ± 2,42, SiC-index = 2,06 ± 3,33. A vizsgált populációban nem találtunk tömött vagy fogszuvasodás miatt eltávolított fogat. A korábban szájhigiénés tájékoztatásban részesült/nem részesült szülok gyermekeinél nem volt szignifikáns különbség a szuvas fogak számának (p = 0,196), a fogyasztott folyadék cukortartalmának (81,5%/71,5%) és a bevitel módjának (p = 0,453) tekintetében. A gyermeküket 6 hónapos korukig kizárólagosan anyatejjel tápláló édesanyák nagyobb eséllyel választották a vízzel történo itatást (75%/52%) pohárból (68,1%/28,8%) a késobbiekben. Az édesanya legmagasabb iskolai végzettsége kulcsszerepet játszik mind az anyatejes táplálás melletti elhivatottságban (felsofok: 53,4%, középfok: 34,2%, alapfok: 37,5%), mind a cariesfrekvencia csökkentésében (p = 0,015). Következtetés: A szüloi szájhigiénés prevenciós tájékoztatás jelenleg nem hatékony. Eredményeink alapján a fogászati szurést 1 éves kor elott meg kell kezdeni, amely a hatékony, rendszeres fogászati prevenciós tanácsadás lehetoségét is megteremtené. Szükségesnek látjuk a védonok és a gyermekháziorvosok folyamatos továbbképzésében a kisgyermekkori fogszuvasodás alapismereteinek integrációját. Orv Hetil. 2021; 162(22): 861-869. INTRODUCTION AND OBJECTIVE: To investigate the frequency of severe early childhood caries (S-ECC) under 3 years of age and to assess the oral health related knowledge of parents/guardians with preschool children. METHOD: 362 children younger than 36 months (mean age: 28.49 ± 5.25 months) were screened and a voluntary questionnaire for their parents was compiled. Statistical analysis was carried out comparing the results of the 306 completed questionnaires with the dental status of the screened children. RESULTS: Caries prevalence in the examined population was 15.46%, df-t index = 0.685 ± 2.20, our suggested modified df-t index based on the number of erupted teeth = 0.758 ± 2.42, SiC-index = 2.06 ± 3.33. No filled or extracted tooth due to caries was found in the study group. There was no significant difference in the number of carious teeth (p = 0.196), consumption of sugar-containing drinks (81.5%/71.5%) and administration of drinks (p = 0.453) in the case of children whose parents had previously received/not received oral hygiene information. Mothers who exclusively breastfed until the age of 6 months were more likely to choose to offer water (75%/52%) from cup (68.1%/28.8%) later. The mother's highest level of education plays a key role in both the commitment to breastfeeding (tertiary: 53.4%, secondary: 34.2%, primary: 37.5%) and in reducing the incidence of caries (p = 0.015). CONCLUSION: Parental oral hygiene preventive instruction is currently ineffective. Based on our results, dental screening should be started before the age of 1 year, that would also provide an opportunity of effective, regular dental prevention counseling. There is a need for the integration of the basics of early childhood caries in the continuous professional training of district nurses and pediatricians. Orv Hetil. 2021; 162(22): 861-869.

Peripheral Blood Lymphocyte Analysis in Oligo- and Polyarticular Juvenile Idiopathic Arthritis Patients Receiving Methotrexate or Adalimumab Therapy: A Cross-Sectional Study.

Juvenile idiopathic arthritis (JIA) is an umbrella term for seven distinct chronic immune-mediated diseases. Disease-modifying anti-rheumatic drugs (DMARD) are used to treat the underlying joint inflammation as well as extra-articular manifestations. Immunosuppression is a considerable side effect of the drugs. The main goal of this study was to investigate the effect of different JIA therapies on leukocyte subpopulations, which play a role in immune-defense. Three study groups were established. The first group consisted of JIA patients treated with methotrexate solely, the second one received a combination of methotrexate (MTX) and adalimumab (ADA). The control group was made up of the patients' healthy siblings. A total of 63 children were recruited. Fourty-one children with JIA and 22 healthy controls were included in the study. The absolute number of CD3+ T-cells was significantly elevated in patients treated with biological therapy compared to healthy controls (p2 = 0.017). In contrast, the number of CD56+ natural killer cells was significantly lower in children receiving biological therapy in comparison with healthy donors (p2 = 0.039). A significant alteration was also demonstrated between patients treated with MTX and MTX/ADA group concerning CD 19+ B-cells (p3 = 0.042). This is the first study that demonstrates significant alterations in the number of B-cells and T-cells with a relative decrease of NK-cell ratios in JIA patients receiving different DMARD therapy. Clinical Trial Registration: NCT03833271. 21.01.2019.

Distribution of bioactive factors in human milk samples.

Background: Breast milk provides nutrition for infants and also contains a variety of bioactive factors that influence the development of the newborn. Human milk is a complex biological fluid that can be separated into different layers (water phase and lipid phase with its component water and lipid fractions). It can affect the developing human body along the whole length of the gastrointestinal tract, and through the circulation, its factors may reach every organ. Methods: In the present study, we analyzed milk samples collected monthly for 6 months from 16 mothers from the 4th week postpartum between 2014 and 2016 in Baranya County, Hungary. The 96 samples provided us information about the fluctuation of certain bioactive factors during the first 6 months of lactation. We investigated with Luminex technology the concentrations of several cytokines (CD40, Flt-3L), chemokines (MCP-1, RANTES, GRO, MIP-1ß, MDC, eotaxin, fractalkine), and epidermal growth factor (EGF). Paired t-tests and one-way ANOVA followed by Bonferroni post-hoc tests were used to compare the data. Results: We detected the presence of each bioactive factor in every layer of the milk samples during the first 6 months of breastfeeding in widespread concentration ranges. In the case of GRO, MIP-1ß, MDC, Flt-3L, fractalkine, and eotaxin, the concentrations were constant during the first 6 months of lactation. The water phase of human milk contained higher factor concentrations compared to both fractions of the lipid phase for most factors (except eotaxin and MIP-1ß). The concentrations of CD40, EGF, MCP-1, and RANTES in the first 3 months were significantly different compared to the values detected between 4th and 6th months. In the water phase, the level of MCP-1 was significantly decreased, while all of the other factors increased during the 4th through 6th months. We found significantly higher EGF, GRO, and RANTES levels in the water fraction compared to the lipid fraction of the lipid phase. Conclusions: The novel findings of this investigation were the presence of Flt-3L and MDC in all layers of breast milk, and nearly all bioactive factors in the lipid phase. Due to their widespread physiological effects these factors may have an essential role in organogenesis.

[Early and late complications of hyperglycemic extremely low birth-weight infants]. / Az extrém alacsony születési súlyú koraszülöttek hyperglykaemiájának korai és késoi szövodményei.

Introduction: During recent decades, the perinatal mortality of extremely low-birth weight infants has decreased. An important task is to recognize complications of prematurity. Aim: We made an attempt to explore the relationship between complications of prematurity and neonatal hyperglycemia. Method: From 1 January 2014 to 31 December 2017, 188 infants with birth weight below 1000 g were admitted. For each infant, the frequencies of hyperglycemia (blood glucose >8.5 mmol/l), retinopathy of prematurity, intraventricular hemorrhage, and bronchopulmonary dysplasia were determined. Animal studies were performed in Sprague Dawley rats. Hyperglycemia was achieved by intraperitoneal injection of streptozotocin (100 mg/kg). On the 7th day of life, aorta sections were prepared and stained with hematoxylin eosin. Wall thickness was measured using QCapture Pro 7 image analysis software. Results: The mean ± SD gestational age and birth weight were 27.1 ± 2.2 weeks and 814.9 ± 151.9 g; 33 infants (17.5%) died. Hyperglycemia was confirmed in 62 cases (32.9%), and insulin treatment was given to 43 infants (22.8%). The gestational age and birth weight of the hyperglycemic infants were significantly lower (p<0.001), the incidence of severe retinopathy (p = 0.012) and the mortality of insulin-treated patients were higher (p = 0.02) than in normoglycemic infants. Among survivors (n = 155), we found by logistic regression analysis that hyperglycemia was a risk factor for severe retinopathy (p<0.001). In the rat model, neonatal hyperglycemia caused significant thickening of the aortic wall. Conclusion: Our studies indicate that hyperglycemia is common in extremely low birth-weight infants. Monitoring of these infants for retinopathy of prematurity, kidney dysfunction, and hypertension is recommended. Orv Hetil. 2019; 160(32): 1270-1278.

Differential scanning calorimetry study of glycerinated rabbit psoas muscle fibres in intermediate state of ATP hydrolysis.

BACKGROUND: Thermal denaturation experiments were extended to study the thermal behaviour of the main motor proteins (actin and myosin) in their native environment in striated muscle fibres. The interaction of actin with myosin in the highly organized muscle structure is affected by internal forces; therefore their altered conformation and interaction may differ from those obtained in solution. The energetics of long functioning intermediate states of ATP hydrolysis cycle was studied in muscle fibres by differential scanning calorimetry (DSC). RESULTS: SETARAM Micro DSC-II was used to monitor the thermal denaturation of the fibre system in rigor and in the presence of nucleotide and nucleotide analogues. The AM.ADP.Pi state of the ATP hydrolysis cycle has a very short lifetime therefore, we mimicked the different intermediate states with AMP.PNP and/or inorganic phosphate analogues Vi and AlF4 or BeFx. Studying glycerol-extracted muscle fibres from the rabbit psoas muscle by DSC, three characteristic thermal transitions were detected in rigor. The thermal transitions can be assigned to myosin heads, myosin rods and actin with transition temperatures (Tm) of 52.9 +/- 0.7 degrees C, 57.9 +/- 0.7 degrees C, 63.7 +/- 1.0 degrees C. In different intermediate states of the ATP hydrolysis mimicked by nucleotide analogues a fourth thermal transition was also detected which is very likely connected with nucleotide binding domain of myosin and/or actin filaments. This transition temperature Tm4 depended on the mimicked intermediate states, and varied in the range of 66-77 degrees C. CONCLUSION: According to DSC measurements, strongly and weakly binding states of myosin to actin were significantly different. In the presence of ADP only a moderate change of the DSC pattern was detected in comparison with rigor, whereas in ADP.Pi state trapped by Vi, AlF4 or BeFx a remarkable stabilization was detected on the myosin head and actin filament which is reflected in a 3.0-10.0 degrees C shift in Tm to higher temperature. A similar effect was observed in the case of the nonhydrolyzable AMP.PNP analogue. Differential DSC measurements suggest that stabilization actin structure in the intermediate states of ATP hydrolysis may play an additional role in actin-myosin interaction.

Effect of polycyclic aromatic hydrocarbons on erythrocyte membranes by DSC and EPR.

Differential scanning calorimetry (DSC) and electron paramagnetic resonance spectroscopy (EPR) experiments were performed on human erythrocyte membranes and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) model systems in order to study the effect the polycyclic aromatic hydrocarbons on lipid structure and dynamics. Eight different compounds among others naphthalene and pyrene were compared, which occur in significant concentrations in dust collected from the air in large cities. Experiments using spin label technique showed that the compounds induced mobility changes in the lipid region in the environment of the fatty acid probe molecules incorporated into the membranes. The effects depended on the structure and concentration of the different compounds. Similarly to EPR observations, DSC measurements reported decrease of transition temperature in comparison to control DPPC vesicles. These results suggest that polycyclic aromatic hydrocarbons were able to modify the internal dynamics of erythrocyte membranes which might lead to damage of the biological functions.

Effect of an educational intervention on Hungarian adolescents' awareness, beliefs and attitudes on the prevention of cervical cancer.

The alarming national data on the mortality and morbidity rates of cervical cancer as well as the results of a Hungarian survey demonstrating adolescents' low level of understanding of human papillomavirus (HPV) infection and HPV vaccination encouraged the authors to conduct an educational intervention. The aim of this survey was to explore the impact of a brief, HPV-focused program on adolescents' knowledge, beliefs and attitudes. A self-administered anonymous questionnaire was completed by 394 male and female adolescents in September, 2010, in Hungary. Half of the students (48.5%) then had a one-off educational intervention on aspects cervical cancer lasting 45 min lesson, while the rest of the participants, the control group, did not have the educational intervention. Three months following the education, both groups were retested using the same questionnaire. Data were analysed using Statistical Package for the Social Sciences (SPSS). Following the education, significant increase was detected in cervical cancer awareness: causal relationship between HPV and cervical cancer (7.9% → 22.1%, p<0.05), or perception of HPV vaccination (61.3% → 85.9%, p<0.05). Similarly, health-related beliefs have enhanced, such as 'HPV may cause cervical cancer' (64.9% → 81.0%, p<0.05) or 'cervical cancer may be prevented by vaccination' (66.5% → 85.3%, p<0.05). Our data also highlighted that Hungarian adolescents have been practising extremely risky sexual behaviour. Nearly half of the sexually active adolescents had engaged in 'one-night relationship' (41.1%) as well as having sexual intercourse without any contraceptive safety measures (44.3%). In addition to providing adolescents with clear and meaningful information about the implications of a HPV infection and addressing their fears of screening and vaccination, health education should focus on promoting safe sex behaviour by promoting the use of condoms and reducing the number of sexual partners to limit the spread of HPV, and also on encouraging the participation in regular cervical screenings, thus reducing the incidence of cervical cancer.

Adolescents' awareness of HPV infections and attitudes towards HPV vaccination 3 years following the introduction of the HPV vaccine in Hungary.

Hungary takes the fourth place regarding the incidence and the fifth regarding the mortality of cervical cancer among the member countries of the European Union, with 500 deaths due to this preventable illness and nearly 1200 new cases diagnosed every year. Although the vaccines have been available for 3 years, the estimated rate of the female population vaccinated against HPV is approximately 10% in the 12-26-year-age cohort. The aim of this study was to determine factors and motivations affecting the uptake of HPV vaccination among Hungarian adolescents. Examining the effects of some possible sociodemographic predictors (age and gender) and the exposure to health information on HPV vaccine acceptability were also focused on, as well as assessing the most trusted sources of information about sexually transmitted diseases (STDs). A nationwide anonymous questionnaire survey with a sample of 1769 students attending public primary or secondary schools was organised by the authors in 16 Hungarian cities and towns. Data were analysed using the Statistical Package for the Social Sciences (SPSS). Adolescents' awareness of HPV was relatively low. Only 35% of the participants reported they had heard about HPV prior to the survey. Almost 70% of the potentially affected study population had not heard about the vaccine previously. Every fourth student did not believe that vaccination against HPV can prevent cervical cancer. If the vaccination was available free of charge, almost 80% of respondents would request it, but in case they had to pay for it, this number would significantly decrease. Significantly better knowledge and also more positive attitudes towards HPV vaccination was found in relation to the number of information sources. The majority of respondents (62-83%) were open for further information about STDs. The main trusted mediators were school-health services (61.3%), education on health at school (49.2%), health professionals (42.2%) and electronic media (24.6%). Since Hungarian adolescent students expect guidance about STDs principally from school health education, an urgent need for well-designed, HPV-focused educational programmes emerges. Launching such programmes would be especially important for the adolescent population to increase their awareness of the risks associated with HPV infection thus reducing the high incidence of cervical cancer in Hungary in the future.

Difficulties in the prevention of cervical cancer: adults' attitudes towards HPV vaccination 3 years after introducing the vaccine in Hungary.

Cervical cancer is one of the most prevalent gynaecological malignancies worldwide. The Hungarian incidence and mortality of this disease take the 4th-5th places within the European Union. A survey including 785 male and female adults was conducted to assess the knowledge and attitudes concerning HPV vaccination. We focused on the difficulties of the primary and secondary prevention of cervical cancer and examined some potential sociodemographic predictors of HPV vaccine acceptability. Our findings have identified some important issues like: incomplete knowledge, intense distrust and financial concerns. Almost half of the college students (45.6%) are unaware of HPV infections. We confirmed previous findings that older age and female gender correlates with better knowledge on STDs, including HPV. We found that greater exposure to health information comes with better knowledge and more positive attitudes towards vaccination. One quarter of survey respondents do not believe that cervical cancer may be prevented by vaccination. More than half of the adults do not trust national health care system and the preparedness of Hungarian doctors. General attitudes towards vaccination are broadly positive, 80% of survey participants had expressed desire towards HPV vaccination, however if there was a need to pay for the vaccination the willingness would decrease by half. Primary prevention through HPV-focused educational programs, clear communication and financial support would be important for public health to reduce the high incidence and mortality of cervical cancer in Hungary in the future.

Lovastatin possesses a fungistatic effect against Candida albicans, but does not trigger apoptosis in this opportunistic human pathogen.

Lovastatin inhibited the growth of Candida albicans in a fungistatic way. Although it triggers apoptosis in a great variety of eukaryotic cells, including many tumour cell lines, lovastatin failed to provoke apoptotic events in this human pathogen. The fungistatic behaviour of this statin might arise from its negative influence on membrane fluidity. Because yeast-->pseudomycelium and hyphae morphogenetic transitions took place under exposure to lovastatin morphogenetic switch and apoptotic cell death must be regulated independently in C. albicans.
