RESUMEN
Objectives: This study aimed to create a three-dimensional histological reconstruction through the AI-assisted classification of tissues and the alignment of serial sections. The secondary aim was to evaluate if the novel technique for histological reconstruction accurately replicated the trabecular microarchitecture of bone. This was performed by conducting micromorphometric measurements on the reconstruction and comparing the results obtained with those of microCT reconstructions. Methods: A bone biopsy sample was harvested upon re-entry following sinus floor augmentation. Following microCT scanning and histological processing, a modified version of the U-Net architecture was trained to categorize tissues on the sections. Detector-free local feature matching with transformers was used to create the histological reconstruction. The micromorphometric parameters were calculated using Bruker's CTAn software (version 1.18.8.0, Bruker, Kontich, Belgium) for both histological and microCT datasets. Results: Correlation coefficients calculated between the micromorphometric parameters measured on the microCT and histological reconstruction suggest a strong linear relationship between the two with p-values of 0.777, 0.717, 0.705, 0.666, and 0.687 for BV/TV, BS/TV, Tb.Pf Tb.Th, and Tb.Sp, respectively. Bland-Altman and mountain plots suggest good agreement between BV/TV measurements on the two reconstruction methods. Conclusions: This novel method for three-dimensional histological reconstruction provides researchers with a tool that enables the assessment of accurate trabecular microarchitecture and histological information simultaneously.
RESUMEN
INTRODUCTION: Policies that reduce tobacco retail density to decrease tobacco use among the youth are critical for the tobacco endgame. This paper reviews a Hungarian tobacco regulatory measure, which, since 2013, has confined the sale of tobacco products exclusively to so-called National Tobacco Shops, summarises the changes in the national tobacco retail marketplace and reports on analyses of the impact of this intervention on illegal sales to minors and adolescent smoking behaviour. METHODS: We reviewed the available national statistical data on the structure and dynamics of the tobacco retail market. Changes in lifetime and current (past 30 days) use of cigarettes among Hungarian adolescents aged 13-17 years were assessed using data from international youth surveys on health behaviours collected in 2010-2020. RESULTS: Since the start of policy implementation, the density of tobacco shops in Hungary decreased by 85%, from 4.1 to 0.6 per 1000 persons. The prevalence of lifetime and current cigarette smoking among adolescents declined by 13-24 percentage points (pp) and by 4.8-15 pp, respectively. The rate of illegal sales of tobacco products to minors decreased by 27.6 pp, although the prevalence of compensatory access strategies, especially asking others to buy cigarettes for minors, increased. CONCLUSIONS: After a significant decrease in the nationwide availability of licensed tobacco retailers, Hungary experienced short-term reductions in youth smoking prevalence. However, the sporadic implementation of complementary, evidence-based tobacco control strategies might limit further declines in youth smoking initiation and tobacco product use.
RESUMEN
Objective: The Hungarian Undiagnosed Lung Cancer (HULC) study aimed to explore the potential reasons for missed LC (lung cancer) diagnosis by comparing healthcare and socio-economic data among patients with post-mortem diagnosed LC with those who were diagnosed with LC during their lives. Methods: This nationwide, retrospective study used the databases of the Hungarian Central Statistical Office (HCSO) and National Health Insurance Fund (NHIF) to identify patients who died between January 1, 2019 and December 31, 2019 and were diagnosed with lung cancer post-mortem (population A) or during their lifetime (population B). Patient characteristics, socio-economic factors, and healthcare resource utilization (HCRU) data were compared between the diagnosed and undiagnosed patient population. Results: During the study period, 8,435 patients were identified from the HCSO database with LC as the cause of death, of whom 1,203 (14.24%) had no LC-related ICD (International Classification of Diseases) code records in the NHIF database during their lives (post-mortem diagnosed LC population). Post-mortem diagnosed LC patients were significantly older than patients diagnosed while still alive (mean age 71.20 vs. 68.69 years, p<0.001), with a more pronounced age difference among female patients (difference: 4.57 years, p<0.001), and had significantly fewer GP (General Practitioner) and specialist visits, X-ray and CT scans within 7 to 24 months and 6 months before death, although the differences in GP and specialist visits within 7-24 months did not seem clinically relevant. Patients diagnosed with LC while still alive were more likely to be married (47.62% vs. 33.49%), had higher educational attainment, and had more children, than patients diagnosed with LC post-mortem. Conclusions: Post-mortem diagnosed lung cancer accounts for 14.24% of total lung cancer mortality in Hungary. This study provides valuable insights into patient characteristics, socio-economic factors, and HCRU data potentially associated with a high risk of lung cancer misdiagnosis.
RESUMEN
Histopathology is the gold standard method for staging and grading human tumors and provides critical information for the oncoteam's decision making. Highly-trained pathologists are needed for careful microscopic analysis of the slides produced from tissue taken from biopsy. This is a time-consuming process. A reliable decision support system would assist healthcare systems that often suffer from a shortage of pathologists. Recent advances in digital pathology allow for high-resolution digitalization of pathological slides. Digital slide scanners combined with modern computer vision models, such as convolutional neural networks, can help pathologists in their everyday work, resulting in shortened diagnosis times. In this study, 200 digital whole-slide images are published which were collected via hematoxylin-eosin stained colorectal biopsy. Alongside the whole-slide images, detailed region level annotations are also provided for ten relevant pathological classes. The 200 digital slides, after pre-processing, resulted in 101,389 patches. A single patch is a 512 × 512 pixel image, covering 248 × 248 µm2 tissue area. Versions at higher resolution are available as well. Hopefully, HunCRC, this widely accessible dataset will aid future colorectal cancer computer-aided diagnosis and research.

Mobile phones have been used to monitor mobility changes during the COVID-19 pandemic but surprisingly few studies addressed in detail the implementation of practical applications involving whole populations. We report a method of generating a "mobility-index" and a "stay-at-home/resting-index" based on aggregated anonymous Call Detail Records of almost all subscribers in Hungary, which tracks all phones, examining their strengths and weaknesses, comparing it with Community Mobility Reports from Google, limited to smartphone data. The impact of policy changes, such as school closures, could be identified with sufficient granularity to capture a rush to shops prior to imposition of restrictions. Anecdotal reports of large scale movement of Hungarians to holiday homes were confirmed. At the national level, our results correlated well with Google mobility data, but there were some differences at weekends and national holidays, which can be explained by methodological differences. Mobile phones offer a means to analyse population movement but there are several technical and privacy issues. Overcoming these, our method is a practical and inexpensive way forward, achieving high levels of accuracy and resolution, especially where uptake of smartphones is modest, although it is not an alternative to smartphone-based solutions used for contact tracing and quarantine monitoring.

Introduction: The Human Resources for Health (HRH) mobility and migration are considered as global phenomena. The European Union often faces the mobility of health professionals on a system level. Hungary is recognised among the sending countries, therefore both international and national level health workforce monitoring, planning, and forecasting are inevitable. Aim: The purpose of this research was to investigate the national demographical profiles of the medical professions affected most significantly by the Hungarian HRH mobility process. Method: Age and regional distribution analyses of the requests for degree certificate issued by the National Healthcare Services Centre were carried out between the years of 2010 and 2017. Results: In Hungary, the rate of mobility - the number of requests for degree certificate among the licensed to practice professionals - resulted in the following: the highest rate was detected in anaesthesiology and intensive therapy with 23.5%, in surgery 17.9%, then internal medicine 7.9%, paediatrics 7.4%, and in general practice 6.4%. According to the results, in the 5 above mentioned professions, the physicians most affected by mobility are mostly from the age cohort of 50+. Furthermore, the results also highlight the territorial inequalities: the region of the capital as well as the medical university towns and counties are in the most favourable situation in terms of professional care and supply. Conclusion: Therefore, it can be concluded that in the case of the 5 investigated subspecialties, not only the overall age of the physicians is higher in the disadvantaged areas, but these regions also have to face a more severe shortage of specialists.

Vast amounts of data are created during routine patient care which are stored in unstructured digital and hardcopy formats in healthcare institutions. Analysis of large databases help to define the healthcare needs of the population and to organize healthcare services for specific diseases. As a model, we selected multiple sclerosis (MS), a disease with well-defined diagnostic criteria, a usually inpatient initial diagnosis, and a need for regular outpatient check-up. Using multiple sclerosis as an example, we set forth to screen and analyze international and Hungarian databases. In the framework of the initiation of the data lake system of Semmelweis University, we aim to define features of the data system needed for disease-specific databases for future applications. To determine essential data-entry criteria for such a database, we review the most important multiple sclerosis registries. We evaluate the type of registered data, structure of database, privacy issues, the availability and ways of application of the databases. Initially, the MS databases were created locally, aiming for better care of patients. As a further step, data were collected for scientific research by national and international co-operations. Disease-specific databases have become of high priority for national healthcare providers, and long-term information on a population ("real-world" data) is extremely important to assess the effectivity and safety of a treatment at the population level. Our analysis contributes to a project which focuses on the aspects of developing a data lake at a service provider level including clinical, diagnostic and digital healthcare departments of Semmelweis University, Budapest, Hungary.

INTRODUCTION: Data during routine patient care are created in multiple digital and paper-based hardcopy systems, therefore their retrieval is cumbersome in the follow-up of patients. Multiple sclerosis is the most prevalent neurological disorder in the young age, with major consequences on health and socio-economic status. AIM: We set forth to create a user-friendly, detailed local database where it is easy to access, register and analyze data. Based on our experiences during building this registry, we develop the model of a modern type of database. METHOD: First we established a local registry in Excel, then data were transferred to the worldwide used iMed system. Separate pages were used to register basic data, follow-up visits, relapses, accompanying diseases, results of neuroimaging, cerebrospinal fluid, evoked response and other tests, pharmacological and non-pharmacological treatments. RESULTS: The database currently contains data of 316 patients. MRI was performed in 96%, cerebrospinal fluid examination in 45% of the patients. The rate of primary progressive disease at disease onset is 9%. Disease modifying treatments were applied in 82% of the patients. CONCLUSION: The traditional manual data entry and data export in PDF format is obsolete and time-consuming. The development of local disease-specific databases appropriate for clinical and research purposes requires continuous and mostly automatic data entry. In future local registries the establishment of uniform documentational language and structure, and automatic transfer of information among different digital systems are required. We present the model of such a registry, which is based on a healthcare data lake. Orv Hetil. 2019; 160(4): 131-137.

BACKGROUND: The WHO Global Code of Practice on the International Recruitment of Health Personnel provides for guidance in health workforce management and cooperation in the international context. This article aims to examine whether the principles of the voluntary WHO Global Code of Practice can be applied to trigger health policy decisions within the EU zone of free movement of persons. METHODS: In the framework of the Joint Action on European Health Workforce Planning and Forecasting project (Grant Agreement: JA EUHWF 20122201 (see healthworkforce.eu)), focus group discussions were organised with over 30 experts representing ministries, universities and professional and international organisations. Ideas were collected about the applicability of the principles and with the aim to find EU law compatible, relevant solutions using a qualitative approach based on a standardised, semi-structured interview guide and pre-defined statements. RESULTS: Based on implementation practices summarised, focus group experts concluded that positive effects of adhering to the Code can be identified and useful ideas-compatible with EU law-exist to manage intra-EU mobility. The most relevant areas for intervention include bilateral cooperations, better use of EU financial resources, improved retention and integration policies and better data flow and monitoring. Improving retention is of key importance; however, ethical considerations should also apply within the EU. Compensation of source countries can be a solution to further elaborate on when developing EU financial mechanisms. Intra-EU circular mobility might be feasible and made more transparent if directed by tailor-made, institutional-level bilateral cooperations adjusted to different groups and profiles of health professionals. Integration policies should be improved as discrimination still exists when offering jobs despite the legal environment facilitating the recognition of professional qualifications. A system of feedback on registration/licencing data should be promoted providing for more evidence on intra-EU mobility and support its management. CONCLUSIONS: Workforce planning in EU Member States can be supported, and more equitable distribution of the workforce can be provided by building policy decisions on the principles of the WHO Code. Political commitment has to be strengthened in EU countries to adopt implementation solutions for intra-EU problems. Long-term benefits of respecting global principles of the Code should be better demonstrated in order to incentivise all parties to follow such long-term objectives.

BACKGROUND: Hungary has been serious facing human resources crisis in health care, as a result of a massive emigration of health workers. The resulting shortage is unevenly distributed among medical specialisations. The findings of research studies are consistent in that the most important motivating factor of the choice of the medical career and of medical specialisations is professional interest. Beyond this, it is important to examine other reasons of why students do or do not choose certain specialisations. The lifestyle determined by the chosen speciality is one such factor described in the literature. METHODS: Using convenient sampling, first year resident medical doctors from each of the four Hungarian universities with a medical faculty were asked to participate in the study in 2008. In total 391 first year resident medical doctors completed the self-administered questionnaire indicating a 57.3% response rate. On the basis of the work of Schwartz et al. (Acad Med 65(3):207-210, 1990), the specialisation fields were divided into the two main categories of non-controllable (NCL) or controllable lifestyles (CL). We carried out a factor analysis on motivating factors and set up an explanatory model regarding the choice of CL and NCL specialisations. RESULTS: Two maximum likelihood factors were extracted from the motivational questions: "lifestyle and income" and "professional interest and consciousness". The explanatory model on specialisation choice shows that the "professional interest and consciousness" factor increases the likelihood of choosing NCL specialisations. In contrast the "lifestyle and income" factor has no significant impact on the choice of CL/NCL specialisations in the model. CONCLUSIONS: Our results confirm the important role of professional interest in the choice of medical specializations in Hungary. On the other hand, it seems surprising that we found no significant difference in the "lifestyle and income" related motivation among those medical residents, who opted for CL as opposed to those, who opted for NCL specialisations. This does not necessarily mean that lifestyle is not an important motivating factor, but that it is equally important for both groups of medical residents.

BACKGROUND: Health workforce (HWF) planning and monitoring processes face challenges regarding data and appropriate indicators. One such area fraught with difficulties is labour activity and, more specifically, defining headcount and full-time equivalent (FTE). This study aims to review national practices in FTE calculation formulas for selected EU Member States (MS). METHODS: The research was conducted as a part of the Joint Action on European Health Workforce Planning and Forecasting. Definitions, categories and terms concerning the five sectoral professions were examined in 14 MS by conducting a survey. To gain a deeper understanding of the international data-reporting processes (Joint Questionnaire on Non-Monetary Health Care Statistics-JQ), six international expert interviews were conducted by using a semi-structured interview guide. RESULTS: Of the 14 investigated countries, four MS indicated that they report FTE to the JQ and that they also calculate FTE data for national planning purposes. The other countries do not use FTE data for national purposes, but most of them do use special calculations and/or estimation methods for converting headcount to FTE. The findings revealed significant differences between national calculation methods when reporting FTE data to the JQ. This diversity in terms of calculations and estimations can lead to biases with respect to international comparisons. This finding was reinforced by the expert interviews, since the experts agreed that the activities of healthcare professionals are a fundamental factor in HWF monitoring and planning. Experts underscored that activity should also be measured by FTE, and not only by headcount. CONCLUSIONS: FTE and headcount are significant factors in HWF planning and monitoring; therefore, national data collections should place emphasis on collecting data and calculating the appropriate indicators. National FTE could serve as a call to action for HWF planners due to the lack of matching international FTE data. At the international level, it is beneficial to monitor the trends and numbers regarding human resources and working time. For the moment, the exchange of information and mutual assistance for developing the capacity to apply common methodology could be a first step towards the standardisation of data collections.

BACKGROUND: The severe shortage of qualified healthcare staff in Hungary cannot be quickly or easily overcome. There is not only a lack of human resources for health, but significant inequalities are widespread, including in geographical distribution. This disparity results in severe problems regarding access to and performance of health care services. In this context, this report, based on research carried out in 2008, deals with a particularly relevant matter: the willingness of young doctors to work outside Budapest (the capital of Hungary). METHODS: We conducted a survey with voluntary questionnaires and focus group interviews at each of the four Hungarian medical schools, concerning career plans and related incentives among young medical doctors. In all, 524 residents responded to the question concerning their willingness to work in rural areas, and there were seven focus group interviews, with 3-7 participants in each group. The number of residents' places in Hungary were 832, 682, and 785 in 2006/2007, 2007/2008, and 2008/2009, respectively. RESULTS: The majority of those surveyed would like to work in Budapest or a large town. Fewer than 7% were willing to work in a town with less than 50 000 inhabitants. Most young doctors would like to work in a teaching hospital (i.e. an accredited training site for medical students and postgraduate trainees) or a major regional hospital. CONCLUSIONS: The current system of medical training in Hungary tends to produce doctors who want to live in big cities and work in central hospitals. Rural regions and non-in-patient service alternatives seem either not to be targeted or seen as unattractive work places.More doctors would be willing to work in smaller towns and villages if in-hospital training was altered and if doctors were offered adequate incentives as part of a comprehensive human resource strategy (high salaries, high professional standards, good working environment, reasonable workload). If these changes do not occur, the existing geographical and structural imbalances will not be improved.
RESUMEN
There is increasing interest in the issue of informal payments for health care in low- and middle-income countries. Emerging evidence suggests that the phenomenon is both diverse, including many variants from cash payments to in-kind contributions and from gift giving to informal charging, and widespread, reported from countries in at least three continents. However, cross-national research is hampered by the lack of consensus among researchers on the definition of informal payments, and the definitions that have been proposed are unable to incorporate all forms of the phenomenon that have been described so far. This article aims to overcome this limitation by proposing a new definition based on the concept of entitlement for services. First, the various forms of informal payment observed in practice are reviewed briefly. Then, some of the proposed definitions are discussed, pointing out that none of the distinctive characteristics implied by these definitions, including illegality, informality, and corruption, is adequate to capture all varieties of the phenomenon. Next, an alternative definition is formulated, which identifies the distinctive feature common to all forms of informal payments as something that is contributed in addition to the terms of entitlement. Then, the boundaries implied by this definition are explored and, finally, the implications for research and policy making are discussed with reference to the lessons developed countries can learn from the experiences of transitional countries.
