[Lung cancer – a review of thirty years. Thoughts about the past struggles, the present results and promises of the future]


[In the past thirty years there was a huge development in the complex treatment of lung cancer. This development is due mostly to the last decade. Nihilism of lung cancer treatment is over and it is a reality that even patients in advanced stage turn out curable by appropriate therapy and their condition may be changed for a chronic disease while using anti-tumour therapy. Thirty years ago, the realistic life expectancy of six to eight months in advanced stage mounted nowadays significantly, and may surpass even five years in a number of cases. It required adequate diagnostic background, which provided the biomarker based treatment. In early stage surgical resection has a fundamental role, coupled with modern complex neoadjuvant and adjuvant treatment, while new surgical techniques also contributed to the improvement of therapeutic results. The same is true for radiation therapy. The same complex strategy is prevailing also in pharmaceutical options, which are dominated by modalities of cytotoxic chemotherapies and targeted immunothe­rapies. Multidisciplinary teams play a significant role in strategic decisions of lung cancer treatment. The future ways are indicating repeated innovations of tar­geted therapies and extended indica­tions of immunotherapy in terms of precision medicine. However, we must keep in mind also the primary and secondary prevention with effective smoking cessation programs and low-dose chest CT scree­ning applied as usual soon in the risk groups. ]

[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.]

[Atherosclerosis: an ancient process in a new interpretation]


[The progress of atherosclerosis starts in childhood and lasts until the body dies. Most cardiovascular diseases and deaths can be traced back to atherosclerotic vascular changes. The process is thousands of years old, but its complex pathophysiology becomes recognized and realised only nowadays. Based on the evidence available today, atherosclerosis is such a chronic inflammatory disease of large- and medium-sized arteries, which is characterized by lipoproteins and immune cells transformed through oxidative and other changes and subendothelial accumulation of extracellular matrix. Innate and adaptive immunity provide a complex regulating system of atherogenesis, which while directing specifically the pro-atherogenic inflammatory and atheroprotective anti-inflammatory processes intensify plaque progression or even stabilize them respectively. With our growing knowledge about the pathology of atherogenesis, we can further improve the identification of cardiovascular risk conditions and apply more personalized therapeutic strategies.]

[Gene modified immune cells: New weapons not exclusively against cancer]


[The oncological breakthrough of the last decade was the application of CD19-specific CAR T cells in different hematologic diseases. Experience gained by clinical trials, coupled with investments of the private stakeholders and the pharmaceutical industry resulted not only in commercial release to the public of already developed CAR T cell products, but drew the atten­tion of many researchers to the potentials of new type immune cells, and their non-oncological administration. This study aims to present briefly those preclinical applications, which approved successfully the administration of CAR T cells in autoimmune and infectious diseases.]

[GLP-1 receptor agonists in the elderly]


[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.]

Neuroscience highlights: Main cell types underlying memory and spatial navigation

KRABOTH Zoltán, KÁLMÁN Bernadette

Interest in the hippocampal formation and its role in navigation and memory arose in the second part of the 20th century, at least in part due to the curious case of Henry G. Molaison, who underwent brain surgery for intractable epilepsy. The temporal association observed between the removal of his entorhinal cortex along with a significant part of hippocampus and the developing severe memory deficit inspired scientists to focus on these regions. The subsequent discovery of the so-called place cells in the hippocampus launched the description of many other functional cell types and neuronal networks throughout the Papez-circuit that has a key role in memory processes and spatial information coding (speed, head direction, border, grid, object-vector etc). Each of these cell types has its own unique characteristics, and together they form the so-called “Brain GPS”. The aim of this short survey is to highlight for practicing neurologists the types of cells and neuronal networks that represent the anatomical substrates and physiological correlates of pathological entities affecting the limbic system, especially in the temporal lobe. For that purpose, we survey early discoveries along with the most relevant neuroscience observations from the recent literature. By this brief survey, we highlight main cell types in the hippocampal formation, and describe their roles in spatial navigation and memory processes. In recent decades, an array of new and functionally unique neuron types has been recognized in the hippocampal formation, but likely more remain to be discovered. For a better understanding of the heterogeneous presentations of neurological disorders affecting this anatomical region, insights into the constantly evolving neuroscience behind may be helpful. The public health consequences of diseases that affect memory and spatial navigation are high, and grow as the population ages, prompting scientist to focus on further exploring this brain region.
