Aging is a process of gradual decline in the functional capacity of the human body that leads to a significant increase in the risk of death over time. Although it is a process universal to all animals, its rate is not the same. Biomarkers of aging aim to better describe the aging process at the level of the individual, organ, tissue, or single cell. They are used to estimate the rate of aging and predict the probability of death. They are good indication of the current state of the organism and are more accurate in predicting a person's susceptibility to disease, its progression and the likelihood of complications and death. Simple biomarkers measure only one parameter or a narrow group of related parameters that have a known association with age, in human or in a laboratory model. They can be divided into molecular (based on features of aging), functional (describing decreasing functional capacity during aging) and anthropometric (describing structural changes). Composite biomarkers are the most comprehensive way of measuring biological age. They combine a large amount of data, which they evaluate using algorithms often based on artificial intelligence. The most widely used method for measuring biological age in composite biomarkers is the epigenetic clock. The aim of this article is to review the many existing markers of aging and describe their relationship to aging.

Professor Přecechtěl's memories of the Balkan Wars of 1912-1913 have various facets and encompass different impressions and phases of these events. They trace the preparations in Prague and the journey to Montenegro, the ancient city of Cetinje among the poor and primitive people, experiences in the Albanian environment plagued by diseases, and the war experienced in Bulgaria. Czech doctors enthusiastically aided their Slavic brethren in the Balkans, who fought for liberation and rights. Initially, they were received coolly and with reservation as the local population had no experience with Czech doctors. However, over time, the medical expeditions proved their worth. Albania presented many obstacles, including a shortage of medicines and suitable food. The army suffered from droughts and exhaustion, leading to high mortality rates and infections. Medical activities were carried out under difficult conditions, lacking hygiene and basic supplies. Despite all the difficulties, the doctors strove to provide help, and their work was invaluable. Memories of the Balkan War are filled with stories of scarcity, challenges, human suffering, and determination to aid and solidarity.

Prohibition has been the globally dominant concept for the regulation and control of psychoactive substances for nearly 70 years. Its effectiveness and legitimacy as a sustainable solution to the problems associated with the existence of psychoactive substances in society has been repeatedly questioned. It is based on the normative assumption that the use of psychoactive substances for other than therapeutic purposes is not allowed, and non-medical supply should be severely punished. This precludes the use of the full range of regulatory, public health, prevention, and harm reduction strategies, reduces well-being, and increases harms for the human-rights, health, and social cohesion. It is time to replace the prohibitionist paradigm with modern regulation that considers the different harms and risks of psychoactive substances, but also the benefits of psychoactive substances for mental health and well-being, lifestyle, and socialisation. This new paradigm (the so-called 'smart regulation') should accept non-medical use of psychoactive substances, apply criminal law as an exceptional tool to regulate human behaviour, regulate the availability of substances according to their harmfulness, regulate the risk profile of the product, strictly regulate marketing and advertising, protect minors and 'others' from the use and supply of psychoactive substances, protect the legal market from the supply of substances from the illegal market, and use economic instruments to regulate demand and to subsidise prevention and treatment.

Imunita po prodělané infekci SARS-CoV-2 byla dlouhodobě zpochybňována. Z jiných typů respiračních onemocnění však víme, že buňky, které se vytvoří při první infekci, dlouhodobě přežívají a při opakované infekci je díky nim imunitní reakce rychlejší a účinnější. Popisuje se zvýšení hladin protilátek, jejich lepší avidita a vznik nových variant. Již existující paměťové B a T lymfocyty jsou použity jako "prototyp", který se dále vylepšuje. U reinfikovaných osob tak logicky klesá riziko vážných průběhů onemocnění. V předkládaném článku jsou uvedeny výsledky dlouhodobého měření hladiny IgG protilátek proti proteinům S a N a IgA protilátek proti proteinu S u 4 osob, které prodělaly opakované infekce SARS-CoV-2 spojené s nárůstem hladin protilátek a s méně závažným průběhem, než měla primoinfekce. Tyto zkušenosti potvrzují i závěry z naší předchozí dlouhodobé studie imunity u seniorů z roku 2020, v níž byla také pozorována reaktivace imunity u rekonvalescentů po pravděpodobné nové expozici SARS-CoV-2, ale bez prodělaného onemocnění. Prezentované výsledky potvrzují již dříve publikovaná fakta, tedy že prodělání nemoci neposkytuje dlouhodobou ochranu před reinfekcí, zvláště novou variantou viru, ale pokud již k reinfekci dojde, bývá její průběh méně závažný než při primoinfekci.

With the rise in obesity and bariatric procedures worldwide, there has been a surge in new and innovative procedures that has been increasingly offered to patients. In this position statement, IFSO highlights the importance of surgical ethics in innovation and when offering new procedures. Furthermore, the task force reviewed the current literature to describe which procedures can be offered as mainstream outside research protocols versus those that are still investigational and need further data.

Catheter-associated urinary tract infections (CAUTI) are among the most common healthcare-associated infections, which increase morbidity, mortality, prolong the length of hospitalization and have a significant impact on the cost of treatment. The most efficient preventive method is removing catheters as soon as possible and avoid unnecessary catheterizations. Treatment of asymptomatic bacteriuria is not recommended. In cases of serious CAUTI, vigorous antibiotic therapy covering multidrug-resistant uropathogens should be initiated. These recommendations are intended for all medical specialties to improve the care of patients with indwelling catheters in the prevention, diagnosis, and treatment of CAUTI in primary care and subsequent long-term care.

Most smokers are addicted to tobacco or nicotine not only psychosocially but also physically, what results in withdrawal symptoms after they miss their dose. These are one of the major barriers to quitting. In the treatment of tobacco dependence, the evaluation of the degree of withdrawal symptoms helps to guide psychobehavioral intervention and, above all, the choice of the type, dose, and duration of pharmacotherapy. The Minnesota Withdrawal Symptoms Scale is one of the most widely used for this purpose, revised in 2020. We present a validated translation of this update.

The international comparison of health systems is a frequently used tool of health policy. It assumes that international experiences are, at least to some extent, transferable from one country to another. The aim of this article is to review selected methods of international comparison of health systems. At the same time, we ask the question of how useful each method is for the evaluation of the Czech health system.

Transfusion, transplantation, and regenerative medicine are rapidly developing fields. The authors of the text want to inform about upcoming legislative changes at the EU level and briefly describe and compare the difficulty of some donation procedures from the point of view of a living donor, as well as their risks, including psychosocial risks. The study is based on a qualitative expert investigation. Comparing the complexity of procedures from the perspective of donors is important, for example, for setting compensations. The tables show that the current compensations are disproportionate.

The aim of the study was to identify and explore barriers to communication between refugees from Ukraine and physicians providing health care, the perspective of physicians was embraced. The focus of the work reflects on the arrival of many forced migrants from Ukraine in 2022. Further, it focuses on the pressure that the presence of migrants' places on the Czech healthcare system, especially in doctor-migrant patient communication. The objectives of this study are also motivated by existing international evidence that misunderstandings and poor-quality communication can lead to lower patient satisfaction and adherence, and consequently poorer healthcare outcomes. The research was carried out in the form of qualitative research, 16 in-depth semi-structured interviews were conducted with physicians providing health care to Ukrainian refugees. Informants were selected using a purposive sampling method to obtain as diverse a sample as possible. The resulting data were analysed by applying thematic coding. The results showed that four main areas of intercultural barriers play a key role in the relationship between physicians and Ukrainian patients. These are: (1) language, (2) differences in healthcare systems, (3) different attitudes towards health and illness and (4) prejudice. The major source of misunderstanding was the difference between the Czech and Ukrainian healthcare systems, which leads to a different position of the patient in the healthcare system. The conclusions prove that intercultural barriers play a significant role in the provision of health care to Ukrainian refugees but can be addressed to a large extent. The current situation in Czechia and the increasing diversity in society call for the need to acquire intercultural competencies in undergraduate and continuing medical education. Similarly, the adoption of measures that promote culturally competent health care is needed.
