ABSTRACT
Postzygotic isolation by genomic conflict is a major cause for the formation of species. Despite its importance, the molecular mechanisms that result in the lethality of interspecies hybrids are still largely unclear. The genus Drosophila, which contains over 1600 different species, is one of the best characterized model systems to study these questions. We showed in the past that the expression levels of the two hybrid incompatibility factors Hmr and Lhr diverged in the two closely related Drosophila species, D. melanogaster and D. simulans, resulting in an increased level of both proteins in interspecies hybrids. The overexpression of the two proteins also leads to mitotic defects, a misregulation in the expression of transposable elements and decreased fertility in pure species. In this work, we describe a distinct six subunit protein complex containing HMR and LHR and analyse the effect of Hmr mutations on complex integrity and function. Our experiments suggest that HMR needs to bring together components of centromeric and pericentromeric chromatin to fulfil its physiological function and to cause hybrid male lethality.

BACKGROUND: The study distinguishes the effect of type 2 diabetes and hypertension on cognitive functions when the two diseases are alone or when they occur together, compared to healthy individuals. METHODS: A total of 143 middle-aged adults were screened using the Wechsler Memory Scale - Revised psychometric test (verbal memory, visual memory, attention/concentration and delayed memory). Participants were divided into four groups based on their diseases: patients with type 2 diabetes (36), patients with hypertension (30), patients having both diseases (33), and healthy controls (44). RESULTS: This study found no differences among investigated groups in verbal and visual memory, however, hypertension and both-disease group performed unfavorably compared to patients with diabetes and to healthy individuals in attention/concentration and delayed memory. CONCLUSIONS: The findings of this study suggest that there is a relationship between hypertension and cognitive dysfunction, whereas type 2 diabetes without consequences was not proved to have an association with cognitive decline in middle-aged people.

Many studies have been published in recent years regarding the fact that moderate wine consumption, as a part of a balanced diet can have a beneficial effect on human health. The biologically active components of wine continue to be the subject of intense research today. In this study, the bioactive molecules of Hungarian aszú from the Tokaj wine region were analyzed using high-performance liquid chromatography (HPLC) and investigated in an in vitro model system of endothelial cells induced by bacterial-derived lipopolysaccharide. The HPLC measurements were performed on a reversed phased column with gradient elution. The non-cytotoxic concentration of the active substance was determined based on 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyltetrazolium bromide (MTT)-, apoptosis, and necrosis assays. The antioxidant effect of the extract was determined by evaluating its ability to eliminate ROS. The expressions of the interleukin-(IL)1α, IL1-ß, IL-6, and IL-8 pro-inflammatory cytokines and nitric oxide synthase (eNOS) at the mRNA level were evaluated using a quantitative polymerase chain reaction (qPCR). We found that the lipopolysaccharides (LPS)-induced increases in the expressions of the investigated cytokines were significantly suppressed by Hungarian aszú extract, excluding IL-6. In our experimental setup, our treatment had a positive effect on the eNOS expression, which was impaired as a result of the inflammatory manipulation. In our experimental model, the Hungarian aszú extract decreased the LPS-induced increases in the expression of the investigated cytokines and eNOS at the mRNA level, which presumably had a positive effect on the endothelial dysfunction caused by inflammation due to its strong antioxidant and anti-inflammatory effects. Collectively, this research contributes to a more thorough understanding of the bioactive molecules of aszú from the Tokaj wine region.

During interphase centromeres often coalesce into a small number of chromocenters, which can be visualized as distinct, DAPI dense nuclear domains. Intact chromocenters play a major role in maintaining genome stability as they stabilize the transcriptionally silent state of repetitive DNA while ensuring centromere function. Despite its biological importance, relatively little is known about the molecular composition of the chromocenter or the processes that mediate chromocenter formation and maintenance. To provide a deeper molecular insight into the composition of the chromocenter and to demonstrate the usefulness of proximity-based biotinylation as a tool to investigate those questions, we performed super resolution microscopy and proximity-based biotinylation experiments of three distinct proteins associated with the chromocenter in Drosophila. Our work revealed an intricate internal architecture of the chromocenter suggesting a complex multilayered structure of this intranuclear domain.

Bed bug infestation rate has gone through an unforeseen increase in the past decades worldwide. Their resurgence is a consequence of numerous factors, including growing population density, increased international travel and the spread of insecticide resistance. Bed bug infestation is often revealed by skin symptoms appearing after their bite in sensitive patients. Medical professionals encountering patients with bed bug bites have responsibility for recognizing the condition and for instructing patients about the necessary measures for eradication. Setting the correct diagnosis, however, is not unequivocal as several skin diseases with autoimmune, immune-mediated aetiology or other arthropod stings and bites may present with similar symptoms. In this review we provide a differential diagnostic guide and an atlas of clinical pictures assigned to the diagnoses. We highlight those dermatological findings where the possibility of bed bug bite arises and identify key elements that help in the differentiation so as to avoid unnecessary diagnostic tests and force early start of extermination.
ABSTRACT
Understanding the molecular basis of hybrid incompatibilities is a fundamental pursuit in evolutionary genetics. In crosses between Drosophila melanogaster females and Drosophila simulans males, an interaction between at least three genes is necessary for hybrid male lethality: Hmrâmel, Lhrâsim, and gfzfâsim. Although HMR and LHR physically bind each other and function together in a single complex, the connection between gfzf and either of these proteins remains mysterious. Here, we show that GFZF localizes to many regions of the genome in both D. melanogaster and D. simulans, including at telomeric retrotransposon repeats. We find that GFZF localization at telomeres is significantly different between these two species, reflecting the rapid evolution of telomeric retrotransposon copy number composition between the two species. Next, we show that GFZF and HMR normally do not colocalize in D. melanogaster. In interspecies hybrids, however, HMR shows extensive mis-localization to GFZF sites, thus uncovering a new molecular interaction between these hybrid incompatibility factors. We find that spreading of HMR to GFZF sites requires gfzfâsim but not Lhrâsim, suggesting distinct roles for these factors in the hybrid incompatibility. Finally, we find that overexpression of HMR and LHR within species is sufficient to mis-localize HMR to GFZF binding sites, indicating that HMR has a natural low affinity for GFZF sites. Together, these studies provide the first insights into the different properties of gfzf between D. melanogaster and D. simulans, and uncover a molecular interaction between gfzf and Hmr in the form of altered protein localization.

BACKGROUND: Adolescents with type 1 diabetes (T1D) can be faced with deterioration in glycemic control (GC), reduced health-related quality of life (HRQoL), and other psychosocial problems. It is important to understand how the disease and its clinical conditions influence HRQoL and how adolescents are able to overcome the life adjustment difficulties. OBJECTIVE: To assess HRQoL of adolescents with T1D from demographic, clinical, personal, and behavioral point of view. SUBJECTS: A total of 229 adolescents with T1D (51.2% males) with a mean age of 15.35 (2.29) years old were recruited from three diabetes centers. The mean diabetes duration was 7.48 (3.87), the mean hemoglobin A1C (HbA1c) level was 10.3 (1.76) mmol/L. METHODS: A multicenter quantitative correlational design study was applied to investigate the influence of sex, age, diabetes duration, GC expressed by HbA1c, intensive insulin regimen, physical activity (PA), resilience (RS), and socioeconomic background on HRQoL. RESULTS: Presence of the diabetes symptoms and worry about the disease has negative impact on the patients' HRQoL. Stepwise multiple regression analyses indicated that insulin pump therapy, male sex, and higher level of RS were significantly related to an increase in HRQoL, whereas the higher level of PA, male sex, and better HRQoL was significantly related to positive change in RS. Patients treated with insulin pump therapy had significantly better HRQoL. CONCLUSIONS: Significant association can be observed between HRQoL and RS. Supposedly, higher level of PA promotes higher level of RS that in turn helps increase HRQoL in adolescents with T1D. Treatment with insulin pump therapy also promotes better HRQoL.

BACKGROUND: Within the frame of National Epidemiological Surveillance System, family physicians have an obligation to report infections and suspicions cases. The aim of this study was to evaluate the knowledge, attitudes, daily practice and the reporting activities of Hungarian family physicians regarding to infectious diseases. METHODS: A self-administered survey was developed, validated and used. The survey was completed by family physicians who had taken part in continuous medical educational programmes of all Hungarian medical faculties. The questionnaire, consisting demographic questions and 10 statements about their reporting habits were completed by 347 doctors, 8% of the total number of family physicians. The data were processed in a cross-sectional design with general linear model. RESULTS: According to the majority of responders, the current reporting system works efficiently. Rural physicians were mainly agreed, that reporting is not a simply obligation, it is a professional task as well. They were less hindered in daily work by reporting activities, waited less for laboratory confirmation before reporting, reported suspicious cases more frequently. Practitioner's based in urban settlements preferred to await laboratory tests before reporting and were hindered less by failures of the electronic reporting system. Older physicians trusted more in the recent system and they wished to increase the number of reports. Female physicians have higher consciousness in epidemiology. They were mostly in agreement that even severe infectious diseases can be diagnosed at primary care level and their daily practices were less burdened by reporting duties. CONCLUSIONS: Both the epidemiological knowledge of general practitioners' and the electronic surveillance systems should be improved. There is a need to develope the electronic infrastructure of primary care. More and regular control is also expected by the health care authorities, beside the synthesis of professional and governmental expectations and regulations.

BACKGROUND: Many studies indicate that a substantial part of the student population drinks excessively, yet most European universities do not have an alcohol policy. In the absence of an alcohol guideline at universities and the easy access to alcohol sold at the student cafeteria, for instance, this has the potential to place students at risk of overconsumption, which has adverse health consequences. OBJECTIVES: Therefore, our study objectives were to explore and compare university students' experiences and attitudes toward alcohol policy on their campus using a qualitative approach. METHODS: 29 focus group discussions (FGDs) were conducted among students from universities in five European countries: Belgium (4 FGDs), Denmark (6 FGDs), France (5 FGDs), Hungary (6 FGDs), and the Slovak Republic (8 FGDs), with a total number of 189 participants. RESULTS: Across the five European countries, students recognized that alcohol was a big problem on their campuses yet they knew very little, if any, about the rules concerning alcohol on their campus. CONCLUSIONS: Students will not support an on campus alcohol restriction and a policy should therefore focus on prevention initiatives.

OBJECTIVES: The objectives of this study were to assess discrepancies between estimated peer and personal drinking behavior and to determine associations between perceptions of peer and personal drinking behavior among university students from Hungary (HU), Lithuania (LT), and the Slovak Republic (SK). METHODS: 2,554 freshman university students completed an online questionnaire on the frequency of their personal alcohol use, the number of heavy drinking occasions and on their perception concerning the corresponding drinking behavior of a typical student. Associations between perceived peer and personal use were analyzed by means of logistic regression, adjusting for sex. RESULTS: The majority of students across all countries thought their peers drink more frequently and are more often involved in heavy drinking occasions than themselves. Students who perceived the frequency of peer alcohol use to be higher were more likely to drink alcohol twice a week or more often (SR: OR = 3.81, 95% CI = 2.51-5.79; LT: OR = 3.16, 95% CI = 2.11-4.75; HU: OR = 2.10, 95% CI = 1.53-2.87) compared with students who drink alcohol monthly or less. Those who perceived the number of peer heavy drinking occasions as high were more likely to report heavy drinking weekly or more often (SR: OR = 3.16, 95% CI = 1.92-5.20; LT:OR = 3.56, 95% CI = 2.14-5.94; HU:OR = 1.41, 95% CI = 0.79-2.51) compared with students who report heavy drinking less than monthly. CONCLUSIONS/IMPORTANCE: University students perceived peer alcohol use to be higher than their personal use. Given the association between perceptions and personal alcohol use, future research should investigate if targeting perceptions in the surveyed countries may have an impact on alcohol use.

OBJECTIVE: To investigate the extent to which romantic relationship status influences condom use during vaginal, oral and anal sex among students from 12 universities in the Czech Republic, Hungary, Lithuania and Slovakia. METHODS: A pilot study of 880 students from the ongoing Student Life Cohort in Europe (SLiCE) study. Multiple logistic regression was conducted to establish the effect of romantic relationship status on condom use during vaginal, anal and oral sex in the previous 30 days, while adjusting for participants' age, gender, use of alcohol and other drugs prior to sex, condom-carrying practices and number of sexual partners. RESULTS: Of the total sample, 73.7% were currently engaged in a romantic relationship and their condom use during vaginal sex (p < 0.001), oral sex (p < 0.001) and anal sex (p = 0.003) was significantly associated with their romantic relationship status. Students who were not in a romantic relationship had the lowest odds of condom use. Use of alcohol or other drugs before sex was detrimental to condom use (odds ratio 0.5; p = 0.045) during vaginal sex. Condom use during vaginal and oral sex was lower among older students. CONCLUSION: The need to target university students with more pragmatic sexual health risk reduction interventions that accommodate the role of romantic relationships on behavioural choices is justified.

INTRODUCTION: This study analysed the causative factors and clinical characteristics of acute and chronic ocular sequelae of Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) treated at a large third-referral centre in a developed country (Hungary) over a 15-year period. METHODS: This was a retrospective review of patients with acute and/or chronic SJS/TEN who were managed between 2006 and 2020 at the Department of Ophthalmology of Semmelweis University in Budapest, Hungary. For each subject, clinical data, including patient demographics, clinical history, causative agents of SJS/TEN, and conservative and surgical treatment details, were reviewed. RESULTS: Ninety-six eyes of 48 patients were included (28 female; 58.3%); the age at disease onset was 32.1 ± 22.4 years. The most common causative factors were medicines (n = 36; 75.0%). Among these drugs, 29.2% were nonsteroidal anti-inflammatory drugs (NSAIDs) (n = 14), 20.8% were antibiotics (n = 10) and 14.6% were antiepileptic drugs (n = 7). In patients with chronic SJS/TEN, the most commonly found ocular sequelae were conjunctival hyperaemia in 45 (56.3%) eyes, symblepharon in 38 (47.5%) eyes, trichiasis/distichiasis in 37 (46.3%) eyes, corneal neovascularization in 31 (38.8%) eyes and corneal scarring in 29 (36.3%) eyes. In patients with chronic SJS/TEN, the most frequently used topical conservative treatment included antibiotics in 53 (66.3%) eyes, preservative-free artificial tears in 50 (62.5%) eyes and topical corticosteroids in 42 (52.5%) eyes of 40 patients. The most frequently performed ocular surgeries for managing chronic ocular sequelae in patients with SJS/TEN were epilation for trichiasis (n = 27; 33.8%), cataract surgery (n = 14; 17.5%), entropion surgery (n = 12; 15.0%), penetrating keratoplasty (PK) (n = 11; 13.8%) and amniotic membrane transplantation (n = 4; 5.0%). CONCLUSION: Our results suggest that NSAIDs, antibiotics and antiepileptic drugs are the most common causative factors for SJS/TEN in Hungary. Like in other countries, in Hungary, the ocular management of patients with acute and chronic SJS/TEN is heterogeneous, and most cases do not follow modern therapeutic guidelines.
ABSTRACT
PURPOSE: The aim of this study was to compare the general health-related quality of life (HRQoL), the metabolic control (HbA1c), the anthropometric measurement, and the cardiorespiratory fitness (expressed by VO2max) in youths with type 1 diabetes treated with continuous subcutaneous insulin infusion (CSII) to those receiving multiple daily injections (MDI). We looked for factors influencing the HRQoL and metabolic control. METHODS: A total of 239 patients treated with CSII (51 girls and 53 boys) or MDI (64 girls and 71 boys) between ages 8 and 18 years were assessed with the Pediatric Quality of Life Inventory, Generic Core Scales, and Diabetes Module. VO2max was evaluated using the 20-meter shuttle run test. RESULTS: CSII group had significantly better HRQoL according to both child self-report and parent proxy-report. Youths with CSII reported better physical, emotional, and school-related functioning, and had less diabetes-related fear and symptoms than the MDI group. There were no significant differences in body mass index z-scores, insulin doses, HbA1c, and VO2max between the groups. HRQoL was predicted by the CSII therapy (ß = -0.220; p = .000) and the VO2max (ß = 0.386; p = .000), other clinical and anthropometric parameters had no effect; the HbA1c was predicted only by VO2max (ß = -0.353; p = .000). CONCLUSIONS: Diabetic youths treated with CSII therapy have better HRQoL than those treated with MDI. There are no differences between the investigated groups in anthropometric data, glycated hemoglobin, and physical fitness. Moreover, good physical fitness has an important role in achieving better metabolic control and HRQoL, which underlines the importance of regular aerobic exercise in the treatment and care of type 1 diabetes in childhood.

INTRODUCTION: Diabetes has been repeatedly associated with a wide variety of cognitive impairments. AIM: To clarify the differences in cognitive dysfunctions between the two types of diabetes. METHOD: Metaanalysis was performed using databases of Medline, PubMed and ScienceDirect (3 studies with type 1 and 6 with type 2 diabetes). RESULTS: Adults with type 1 diabetes showed lower performance than control subjects in all fields. The effect size had the highest value in psychomotor activity (D = -0.69). The effect size was small for delayed verbal memory (D = -0.48), attention (D = -0.47), language (D = -0.44), visual processing (D = -0.35), immediate verbal memory (D = -0.30), working memory (D = -0.27) and executive functions (D = -0.26). Adults with type 2 diabetes showed lower performance than control subjects in all cognitive domains, except for working memory (D = +0.03). The effect size had the highest value in immediate verbal memory (D = -1.12), psychomotor activity (D = -0.82) and delayed verbal memory (D = -0.81). The effect size was moderate for general intellectual abilities (D = -0.68) and small for general memory (D = -0.37), attention (D = -0.35), language (D = -0.35), visual processing (D = -0.33) and executive functions (D = -0.33). CONCLUSION: Both types of diabetes are associated with reduced performance in numerous cognitive domains.

The aim of our review article was to summarize the current literature on Stevens-Johnson syndrome (SJS) and its severe form, toxic epidermal necrolysis (TEN). SJS/TEN is a serious, rare multi-system, immune-mediated, mucocutaneous disease with a significant mortality rate that can lead to severe ocular surface sequelae and even to bilateral blindness. Restoration of the ocular surface in acute and chronic SJS/TEN is challenging. There are only limited local or systemic treatment options for SJS/TEN. Early diagnosis, timely amniotic membrane transplantation and aggressive topical management in acute SJS/TEN are necessary to prevent long-term, chronic ocular complications. Although the primary aim of acute care is to save the life of the patient, ophthalmologists should regularly examine patients already in the acute phase, which should also be followed by systematic ophthalmic examination in the chronic phase. Herein, we summarize actual knowledge on the epidemiology, aetiology, pathology, clinical appearance and treatment of SJS/TEN.
ABSTRACT
AIMS: To evaluate motor performance and cardiorespiratory function in youths with type 1 diabetes in comparison with age-matched control groups and to analyze the influence of physical activity level, anthropometric and physical fitness parameters on long-term metabolic control. METHODS: 106 youths with diabetes and 130 healthy youths aged 8-18 were assessed by the Eurofit test regarding motor performances, cardiorespiratory fitness (VO2max), skinfold thickness, and body mass index. Physical activity level was assessed through the use of questionnaires. Predictors of physical fitness and metabolic control were determined with regression analysis. RESULTS: There were no differences either in body composition or in physical activity level, but younger girls with diabetes had impaired results in speed of upper limb movement, abdominal muscle strength, upper body strength, running speed, and VO2max ; older girls with diabetes had poor results in speed of upper limb movement, abdominal muscle strength, upper body strength and VO2max . Younger boys with diabetes had impaired results in speed of upper limb movement, flexibility, static strength of hand, and abdominal muscle strength; and older boys with diabetes had poor results in speed of upper limb movement, flexibility, abdominal muscle strength, upper body strength, and VO2max compared with control groups. Older age, female gender, lower physical activity level, and higher HbA1c were significant independent predictors of poorer VO2max. Better VO2max proved to be the single predictor of favorable HbA1c . CONCLUSIONS: Youths with diabetes have reduced fitness parameters. Efforts should be carried out to improve physical fitness as part of treatment and care of children and adolescents with type 1 diabetes.

Background and aim: A continuous glucose monitoring (CGM) helps the user stay continuously informed about blood glucose levels and reach the right target range. This study aimed to compare glycemic control and mental health of adults with type 1 diabetes with or without CGM and to examine their experiences using it. Methods: Patients were included in the survey, whether or not they had used a CGM. Standardized questionnaires were used to assess mental health, problems with disease management, hypoglycemia attitudes and behavior, as well as glucose monitoring satisfaction. Results: 277 people participated in the study. CGM users (61.3%) had a more favorable glycemic control than those who were not. No differences were observed between the 2 groups in mental health and in response to hypoglycemic events; however, users reported more disease-related problems. CGM users reported they felt more open and free about diabetes, however, the pain and skin irritation caused by the device was disturbing and it was difficult to cope emotionally with the constant thought and worrying about diabetes. Conclusions: CGM did not show clear satisfaction among users, however, less fear of hypoglycemia, fewer depression symptomology and improved glycemic control indicate better clinical status, which is one of the most important goals of disease management.

Paraneoplastic mucous membrane pemphigoid, a rare pemphigoid variant is associated with primary malignancy, and characterised by fulminant progression and frequent ineffectivity of classical systemic immunosuppression. In this paper, the clinical features, diagnostic and therapeutical challenges are presented through three cases. Detailed history and analysis of the immunofluorescent samples help the diagnosis. The therapeutic goal is to prevent the progression with systemic immunosuppressive treatment, which can be contraindicated during the ongoing oncological therapy. In absence of consent in the exact diagnostic criteria and management protocol of this rare condition, consultation with other specialists (ophthalmologist, dermatologist, dentist, ear-nose-throat specialist, immunologist) has high importance in early diagnosis and treatment.

In this study, generic health-related quality of life (HRQoL) of young children with type 1 diabetes (T1D) was compared to healthy peers taken in consideration of family functioning and psychological well-being of mothers. A total of 113 mothers provided data (28 mothers had a preschool-aged child with T1D). There were no significant differences in background parameters of two investigated groups. No significant differences between children with and without T1D were detected either in HRQoL or in family functioning. Moreover, mothers of children with diabetes reported lower levels of resilience and more depressive symptoms than mothers of healthy peers. In the regression analysis, mothers' depressive symptoms and the family functioning significantly affected children's HRQoL regardless of the presence of diabetes. These results suggest that parents of children with T1D handle the burden of diabetes well and integrate into the daily activities of the families. Mothers experience distress, presumably because diabetes management is burdensome; however, the family can function well and the young children can live in a similar way to their healthy peers.

UNLABELLED: Due to the lack of validated age- and disease-specific instruments, there are limited health-related quality of life measurements in type 1 diabetes youths in Hungary. OBJECTIVE: To culturally adapt the Pediatric Quality of Life Inventory™ 3.0 Diabetes Module. METHOD: Feasibility, internal consistency reliability, reproducibility, convergent, discriminant and concurrent validities were evaluated in 134 type 1 diabetes youths. RESULTS: Low scale-level mean percentage of missing item responses, minimal floor and moderate ceiling effects supported the feasibility. Cronbach α exceeded the internal consistency reliability standard of 0.70. Concordance between the children's and the parents' reports was strong. The instrument differentiated between the quality of life of patients having acceptable and poor metabolic control. Intercorrelations between the Generic Module and Diabetes Module had moderate to large effect sizes. CONCLUSIONS: The results demonstrate the feasibility, reliability and validity of the instrument, but further research should be carried out for generalization for Hungarian population.
