[Metoprolol treatment in dialated cardiomyopathy]

DÉKÁNY Miklós, NYOLCAS Noémi, FIÓK János, VÁNDOR László, SEREG Mátyás, BALOGH Ildikó

[Authors applied metoprolol for treating heart failure in with dilated cardiomyopathy. Patients were given digitalis, diuretics as well as ACE-inhibitor and vasodilator drugs. The grade of heart failure was according to NYHA classification in the mean 2.5 class. For assessing the effect of metoprolol clinical variables and results of non-invasive tests were evaluated and compared in 3 consecutive periods: 1) before starting metoprolol, 2) 2–4 weeks after reaching its definitive dose (short-term effect), 3) 3-6 months later (medium-term effect). Early intolerance appeared in 3 patients; signi ficant progression of heart failure in 2 and hypotension causing complaints in 1. Evaluating the actually treated 17 patients clinical signs of heart failure (NYHA class) decreased, left ventricular ejection fraction improved, though not significantly in case of every considered variables, left atrial filling pressure decreased, exercise capacity did not alter, rate-pressure product decreased at rest and at low level of exercise as well. The authors stress the significance of "up-regulation" of myocardial beta-1 receptors in the reduction of myocardial toxic catecholamin effect and myocardial oxygen demand as well as in the increase of myocardial blood supply. Referring to the data of the respective literature and to their own experiences the authors suggest metoprolol treatment in cases of dilated cardiomyopathy, where previus therapy did not prove to be efficient.]

[Role of oxygen derived free radicals during myocardial reperfusion]

KÓNYA László , FEHÉR János, JUHÁSZ Nagy Sándor

[Oxygen derived free radicals are now considered to be important contributors to tissue (myocardium) injury associated with ischemia and reperfusion. Normaly the tissue concentration of these toxic intermediate products of oxygen is strietly limited, but production of oxygen free radicals overwhelming the capacity of the tissue elimination may cause serious damage. Thus reperfusion has it's own danger with the extension of the injury produced by the ischemia alone. Several experi mental studies have shown that different free radical scavengers can reduce the post-ischemic tissue injury, however, there are contradictory results and unresolved problems. Further investigation is necessary to establish the relevance of oxygen free radical mediated myocardial injury and the effective antioxidant treatment. ]

[Autoimmunity and the network of the antibody-forming cells: the "immunological homunculus"]

UHER Ferenc

[Frank M. Burnet's clonal selection theory declares the deletion and/or anergy of self-reactive clones to be the fundamental mechanism responsible for self tolerance. There is ample evidence, however, that all healthy individuals have lymphocytes and , natural” antibodies that recognize self structures. In the 1970s, Niels K. Jerne postulated the network theory. It is based on the idea that the idiotype, the region of an immunoglobulin that is unique because it comprises the antigen-binding portion of the molecule, can act as both antigen and antibody within the same individual. Network theory views the immune system as a single, highly interconnected system, through idiotypes, a web of V domains. Antonio Coutinho adressed this problem and divided the repertoire of the B lymphocytes into two parts. He suggested that a set of naturally activated cells and the immunoglobulins they secrete, is reflected in the autonomous immune activities of the self-related network as the central immune system. In contrast, immune responses to external antigens are essentially allonomous clonal activities of another set of resting, rapidly turning over lymphocytes that follow the predictions of the clonal selection theory, making up the peripheral part of the system. Finally, Irun R. Cohen suggested that some, perhaps all, major autoantigens are indeed dominant because each one of them is encoded in the organizational structure of the immune system. This picture was termed the immunological homunculus by its analogy to the picture of the body encoded in the central nervous system. ]

[Modern therapy of intracerebral and subarachnoidal hemorrhages]


[The frequency of the intracerebral hemorrhages among the strokes is most commonly quoted around 10 percent. The rupture of an intracranial aneurysm is often complicated with subarachnoideal hemorrhage as well as with intracerebral hematoma therefore this latter type of intraparenchymal hemorrhage may also be discussed in this topic. The modern imaging procedures (Computed to mography, Nuclear magnetic resonance) are of crucial importance in the urgent and exact diagnosis of intracranial hemorrhages. The first essential step in the diagnosis of stroke is to distinguish the ischemic lesion from the hemorrhage by means of CT. When an intra cerebral hemorrhage threatens life and the patient's condition is relatively good there must be an urgent decision considering the choice between medical therapy or surgical intervention. Although clearcut indications for surgery are now available, the clinical and computed tomographic guidelines play indi vidually an important role in the final decision. The individual judgment is always desirable in every case of intracerebral hemorrhage as well as in the surgical intrvention of intracranial aneurysm during the acute phase (two days).]

Fluoxetine use is associated with improved survival of patients with COVID-19 pneumonia: A retrospective case-control study

NÉMETH Klára Zsófia, SZÛCS Anna , VITRAI József , JUHÁSZ Dóra , NÉMETH Pál János , HOLLÓ András

We aimed to investigate the association between fluoxetine use and the survival of hospitalised coronavirus disease (COVID-19) pneumonia patients. This retrospective case-control study used data extracted from the medical records of adult patients hospitalised with moderate or severe COVID-19 pneumonia at the Uzsoki Teaching Hospital of the Semmelweis University in Budapest, Hungary between 17 March and 22 April 2021. As a part of standard medical treatment, patients received anti-COVID-19 therapies as favipiravir, remdesivir, baricitinib or a combination of these drugs; and 110 of them received 20 mg fluoxetine capsules once daily as an adjuvant medication. Multivariable logistic regression was used to evaluate the association between fluoxetine use and mortality. For excluding a fluoxetine-selection bias potentially influencing our results, we compared baseline prognostic markers in the two groups treated versus not treated with fluoxetine. Out of the 269 participants, 205 (76.2%) survived and 64 (23.8%) died between days 2 and 28 after hospitalisation. Greater age (OR [95% CI] 1.08 [1.05–1.11], p<0.001), radiographic severity based on chest X-ray (OR [95% CI] 2.03 [1.27–3.25], p=0.003) and higher score of shortened National Early Warning Score (sNEWS) (OR [95% CI] 1.20 [1.01-1.43], p=0.04) were associated with higher mortality. Fluoxetine use was associated with an important (70%) decrease of mortality (OR [95% CI] 0.33 [0.16–0.68], p=0.002) compared to the non-fluoxetine group. Age, gender, LDH, CRP, and D-dimer levels, sNEWS, Chest X-ray score did not show statistical difference between the fluoxetine and non-fluoxetine groups supporting the reliability of our finding. Provisional to confirmation in randomised controlled studies, fluoxetine may be a potent treatment increasing the survival for COVID-19 pneumonia.

Cholinesterase inhibitors and memantine for the treatment of Alzheimer and non-Alzheimer dementias


In aging societies, the morbidity and mortality of dementia is increasing at a significant rate, thereby imposing burden on healthcare, economy and the society as well. Patients’ and caregivers’ quality of life and life expectancy are greatly determined by the early diagnosis and the initiation of available symptomatic treatments. Cholinesterase inhibitors and memantine have been the cornerstones of Alzheimer’s therapy for approximately two decades and over the years, more and more experience has been gained on their use in non-Alzheimer’s dementias too. The aim of our work was to provide a comprehensive summary about the use of cholinesterase inhibitors and memantine for the treatment of Alzheimer’s and non-Alzheimers’s dementias.

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

[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. ]

[Operational Efficiency Investigation from APN Perioperative Perspective]


[In the healthcare system operating theatres have to put great emphasis on quality work, patient safety and efficiency as well, and to achieve this, optimal utilization of theatres is extremely important. The results of researches in this topic in Hungarian and international literature draw attention to a lot of aspects. The study of perioperative periods, and the evaluation of the analysed processes show that theatres could be operated more effectively. As a result of this, more operations could be carried out and waiting time would also reduce. In order to increase the efficiency of the processes, APNs can play a prominent role at several points. According to the experience, the number of people using health care and the number of people waiting for surgery is increasing, which is further increased by the development of the ongoing SARS-CoV-2 (COVID-19) epidemic. Thereby, patients are not satisfied with the service. The work of APNs would also help increasing the contentment of patients during the operation procedures. Taking advantage of the multifunctional role of the nurse due to her knowledge and training, she actively participates in the operation, in the smooth running of the scheduled daily surgical program and contributes to the reduction of the number of missed, planned surgeries.]

[Use of the ankle-brachial index in occupational healthcare]

SZOBOTA Lívia, HIRDI Henriett Éva

[Elevated risk of fatal and non-fatal cardiovascular events is associated with high prevalence of peripheral arterial disease (PAD). Nurses working in occupational healthcare are ideally situated to identify individuals with undiagnosed PAD. The aim of the study: This study aimed to demonstrate that the ankle-brachial index (ABI) is a tool to be used by occupational health nurses in prevention of cardiovascular disease (CVD). A cross-sectional study was carried out with patients (N=638) from an occupational healthcare setting in 2021. The ABI was measured with an oscillometric blood pressure device. The measurements were analysed with the help of SPSS 22.0; descriptive statistics were calculated. A total of 638 patients were included. Mean age of the population studied was 46.5 ± 8.2 years; 38.4% were men and 61.6% were women. Mean ABI were 1.08 in right legs, 1.06 in left legs. Only 11 subjects (1.72%) had an ABI < 0.90. Occupational health nurses are able to identify key factors related to PAD, including use of the ABI, and to identify individuals with the disease. The determination of ABI using an oscillometric blood pressure device is feasible and easy to implement in occupational healthcare.]
