[Family planning in multiple sclerosis: conception, pregnancy, breastfeeding]

RÓZSA Csilla

[Family planning is an exceptionally important question in multiple sclerosis, as women of childbearing age are the ones most often affected. Although it is proven that pregnancy does not worsen the long-term prognosis of relapsing-remitting multiple sclerosis, many patients are still doubtful about having children. This question is further complicated by the fact that patients – and often even doctors – are not sufficiently informed about how the ever-increasing number of available disease-modifying treatments affect pregnancies. Breastfeeding is an even less clear topic. Patients usually look to their neurologists first for answers concerning these matters. It falls to the neurologist to rationally evaluate the risks and benefits of contraception, pregnancy, assisted reproduction, childbirth, breastfeeding and disease modifying treatments, to inform patients about these, and then together come to a decision about the best possible therapeutic approach, taking the patients’ individual family plans into consideration. Here we present a review of relevant literature adhering to international guidelines on the topics of conception, pregnancy and breastfeeding, with a special focus on the applicability of approved disease modifying treatments during pregnancy and breastfeeding. The goal of this article is to provide clinicians involved in the care of MS patients with up-to-date information that they can utilize in their day-to-day clinical practice. ]

[Immunotherapy of hepatocellular carcinoma]

DEMETER Gyula

[The systemic treatment of HCC was based exclusively on sorafenib near 10 years. In the past 2-3 years some new molecules demostrated their effectivites in phase III clinical trials. So the immuncheckpoint-inhibitors (ICI) demands their place in systemic treatment of HCC. Nivolumab and pembrolizumab are recommended already in second line in NCCN and ESMO clinical guidelines. Nivolumab demostrated his effectivity against the standard treatment sorafenib in a phase III clinical trial, although the results were not signifi cant. However, the combination treatment of atezolizumab and bevacizumab seems better than sorafenib in a phase III clinical trial, so the combination is recommended already in fi rst line in the NCCN guideline. There are more clinical trials with ICIs in progress as in monotherapy as in combination therapy with other modalities.]

[Second game, 37th move and Fourth game 78th move]

VOKÓ Zoltán

[What has Go to do with making clinical decisions? One of the greatest intellectual challenges of bedside medicine is making decisions under uncertainty. Besides the psychological traps of traditionally intuitive and heuristic medical decision making, lack of information, scarce resources and characteristics of doctor-patient relationship contribute equally to this uncertainty. Formal, mathematical model based analysis of decisions used widely in developing clinical guidelines and in health technology assessment provides a good tool in theoretical terms to avoid pitfalls of intuitive decision making. Nevertheless it can be hardly used in individual situations and most physicians dislike it as well. This method, however, has its own limitations, especially while tailoring individual decisions, under inclusion of potential lack of input data used for calculations, or its large imprecision, and the low capability of the current mathematical models to represent the full complexity and variability of processes in complex systems. Nevertheless, clinical decision support systems can be helpful in the individual decision making of physicians if they are well integrated in the health information systems, and do not break down the physicians’ autonomy of making decisions. Classical decision support systems are knowledge based and rely on system of rules and problem specific algorithms. They are utilized widely from health administration to image processing. The current information revolution created the so-called artificial intelligence by machine learning methods, i.e. machines can learn indeed. This new generation of artificial intelligence is not based on particular system of rules but on neuronal networks teaching themselves by huge databases and general learning algorithms. This type of artificial intelligence outperforms humans already in certain fields like chess, Go, or aerial combat. Its development is full of challenges and threats, while it presents a technological breakthrough, which cannot be stopped and will transform our world. Its development and application has already started also in the healthcare. Health professionals must participate in this development to steer it into the right direction. Lee Sedol, 18-times Go world champion retired three years after his historical defeat from AlphaGo artificial intelligence, be­cause “Even if I become the No. 1, there is an entity that cannot be defeated”. It is our great luck that we do not need to compete or defeat it, we must ensure instead that it would be safe and trustworthy, and in collaboration with humans this entity would make healthcare more effective and efficient. ]

[Focus on Lege Artis Medicinae (LAM)]

VASAS Lívia, GEGES József

[Three decades ago, LAM was launched with the goal of providing scientific information about medicine and its frontiers. From the very beginning, LAM has also concerned a special subject area while connecting medicine with the world of art. In the palette of medical articles, it remained a special feature to this day. The analysis of the history of LAM to date was performed using internationally accepted publication guidelines and scientific databases as a pledge of objectivity. We examined the practice of LAM if it meets the main criteria, the professional expectations of our days, when publishing contents of the traditional printed edition and its electronic version. We explored the visibility of articles in the largest bibliographic and scientific metric databases, and reviewed the LAM's place among the Hun­ga­rian professional journals. Our results show that in recent years LAM has gained international reputation des­pite publishing in Hungarian spoken by a few people. This is due to articles with foreign co-authors as well as references to LAM in articles written exclusively by foreign researchers. The journal is of course full readable in the Hungarian bibliographic databases, and its popularity is among the leading ones. The great virtue of the journal is the wide spectrum of the authors' affiliation, with which they cover almost completely the Hungarian health care institutional sys­tem. The special feature of its columns is enhanced by the publication of writings on art, which may increase Hungarian and foreign interest like that of medical articles.]

[Prevention and treatment of venous thromboembolism in cancer patients]

[Venous thromboembolism (VTE) is a common and severe complication of cancer. Deep vein thrombosis and pulmonary embolism are the second most common cause of death in cancer patients. Cancer, tumor-related factors as well as patient’s general condition and comorbidities are responsible for the increased risk of VTE. Chemotherapy is one of the most important risk factors for VTE, increasing incidence of VTE by 6.5-fold. In my paper, current guidelines for cancer VTE prevention and treatment are reviewed. Hospitalized patients with active tumor are at higher risk for VTE, and thrombosis prophylaxis is recommended in all cases. Extensive, routine prophylaxis for advanced cancer patients receiving chemotherapy is not recommended, but may be considered in high-risk ambulatory cancer patients (Khorana-score ≥ 3). Risk factors may change during the course of cancer disease, and the score should be continually reviewed and prophylactic treatment changed as necessary. LMWH is the recommended agent for both primary and secondary prophylaxis/treatment. Direct oral anticoagulants (DOACs) are knocking on our door, but results from further clinical trials are pending to determine their exact role.]

[The role of stress management in the care of hypertension and the treatment of cardiovascular disease]

SOMOGYI Éva, KISS Zoltán, STAUDER Adrienne

[The aim of this paper is to give an overview of the relationship between stress and hypertension and cardiovascular diseases, furthermore to introduce an evidence based stress management intervention available in Hungary. The correlation between cardiovascular disease and psychosocial factors (including concomitant mental disorders as well as personality traits or the effect of social environment) has been established in numerous studies aimed at investigating pathogenesis or various clinical endpoints. The 2016 Guidelines of the European Society of Cardiology include the assessment and the management of psychosocial problems with behavioral medicine interventions as a I.A level recommendation. The implementation of these guidelines in everyday clinical practice is crucial to decrease cardiovascular risk. This involves the training of health care professionals, the facilitation of multidisciplinary collaboration and the integration of behavioral intervention into everyday care. The Williams Life Skills (WLS) program is an evidence based behavioral medicine intervention aiming to improve stress management and communication skills which implemented internationally and also available all over Hungary. It involves the learning of simple coping strategies that facilitate the successful management of every day psychosocial stress situations and the self-conscious reduction of bodily and psychological tensions. In cardiovascular disease, this improves quality of life and survival. The WLS program is especially recommended for healthcare workers to decrease the negative health consequences of their high stress load and to prevent burnout. Stress may affect both doctors and patients during their interactions. Bálint groups have a positive impact on the physician-patient collaboration and help to reduce burnout by improving the understanding of the diseases from a more complex approach.]

[Similarities and differences of the most significant international guidelines for the treatment of hypertension]

KÉKES Ede, VÁLYI Péter

[Guidelines of diagnosing and treating hypertension play pre-eminent role in maintaining health in our World. Based on reliable estimates we have to take in ac­count more than 1.6 billion individuals suffering from hypertension by 2025. Ad­he­rence to the guidelines is a vital issue for all high blood pressure patients, however, also the economically developed countries have a disappointing share of well-controlled hypertension. Unfortunately, on the 5 continents of the world, the guidelines provide different or very different recommendations for measuring blood pressure, making diagnosis, estimating cardiovascular risk, and setting a target value, although an attempt has been made in the recent years for developing “consensus” in specific issues. This study presents the different opinions and resolutions by analysing the ACC/AHA, ESC/ESH, NICE, Canadian and Australian guidelines. WHO and ISH resolutions were also concerned. We describe the mutual ad­justment in theoretical and practical terms of the guidelines and the consensus that have already been estab­lished.]

[Teleconsultations in general practice during coronavirus epidemiological emergency]

PAPP Renáta, OBERFRANK Ferenc, BALOGH Sándor

[Modifications of operating the health care belong to the preventive measures of the COVID-19 epidemic. Their priority period was the time interval between March 21, and May 3, 2020. Teleconsultation played an emphasized and dedicated role among General Practitioners (GPs) and the range of health services available through telemedicine was published by the legislation. In the present study, we evaluated the experiences of GPs according to the mandatory family practice guidelines in this period using electronically administered questionnaires sent back by the GPs themselves. 83% of respondents considered that the number of patients consulted by teleconsultations increased significantly if contrasted to the pre-epidemic period. Of the tools used in teleconsultation, all respondents mentioned the telephone, 85.5% mentioned e-mail, while 40% also included social media applica­tions. Prescribing drugs to known chronic patients and documentation were most feasible without face-to-face ap­pointment. 96.5% of GPs responded that they are ready to use teleconsultation even after the epidemiological emergency. We conclude that the GPs met the requirements and responded quickly to the introduction of telemedicine in the epidemiological emergency, which reduced effectively personal contacts in the health care, and according to the feedbacks, “remote” cases got solved successfully. Additionally, telemedicine has also its place in the GP offices in terms of patient care and specialist consultations as well. The implementation of telemedicine is expected to provide opportunities for more rational patient care and management. The development of telemedicine protocols is necessary and actual to support patient safety and medical responsibility.]

[GLP-1 receptor agonists in the elderly]

WINKLER Gábor

[According to current guidelines of type 2 diabetes, treatment, glucagon-like pep­tide (GLP) -1 receptor agonists (RAs) are primary suggested drugs of the early antidiabetic medication, just after the first an­ti­­diabetic metformin. However, more and more arguments support their optional application in old age diabetes. These include multi-target strong glycemic ef­fects, low risk of hypoglycaemia, proven cardio- and nephroprotective nature of long- and ultra long-acting derivatives, multifaceted be­neficial pleiotropic effects, as well as the appearence of their fixed combinations with analogue basal insulins effective in weight loss and lowering the blood pressure. This study reviews specific aspects of blood sugar lowering treatment in the elderly and the potential benefits of choosing GLP-1 RAs in this age group. While presenting data of relevant literature and own experiences it is emphasized, that these preparations can be used safely in long term also in this age group.]

[Treatment of hypertension in patients with chronic renal failure]

SZLOVÁK Edina, SZILVESZTER Dolgos

[The prevalence of chronic renal failure and hypertension is steadily increasing worldwide. The risk of possible cardiovascular death in patient with advanced renal failure is greater than the risk of progression to end-stage renal failure. Therefore treating and achieving target blood pressure is important in order to slow renal function decline in parallel with cardiovascular risk reduction. However, guidelines do not specify a single blood pressure target to be achieved in patients with renal failure, but suggest evidence based, reno- and cardioprotective therapy. This paper summarizes the clinical practice of treating hypertension (drug and nondrug treatment, therapeutic algorithm, target value, effectiveness of therapy) in patients with chronic renal failure.]
