The article summarize the most important changes regarding the management of valvular heart disease, which have been made in the ESC Guidelines 2021. Based on the randomized clinical study data, which were recently published, the most frequent changes were done in terms of the choice of mode of intervention in the aortic and mitral valves as well as in the management of the antithrombotic therapy.

Levothyroxine therapy in management of diferentiated thyroid carcinoma (DTC) has been common practice for decades. Levothyroxine is being administered to patiens with DTC after total thyreoidectomy (with or without postopreative radioiodine treatment) not only to restore euthyroidism but to suppress the production of thyroid-stimulating hormone (TSH) as well because TSH is considered as a growth factor for thyroid follicular cells. However there has been a downside to this threatment recently. The main concerns are the known risks related to iatrogenic subclinical or even mild but clinicaly overt iatrogenic hyperthyroidism. Therefore individualized treatment approach aiming to balance between the risk of tumor recurence and the risks related to hypertyhroidism in view of pateints age, risk factors and comorbidities is essential. Close folow-up is therefore necessary with frequent dose adjustments according to target TSH values published in American Thyroid Association guidelines.

Gut microbiome research has been a surge of interest in many branches of medicine in the last decade. Our main aim is to show ability of microbes to infuence the functions of human body, especially in the immune system, and on the other hand to clarify changes in composition of gut microbiome in the post-transplantation period and their function for the long-term survival of the graft and the patient in the context of the occurrence of a wide range of complications. Kidney transplantation with the subsequent use of immunosuppressants and antibiotics affects the composition of gut microbiome. The subsequent development of dysbiosis significantly increases the risk of acute rejection, interstitial fibrosis and tubular atrophy of the graft, post-transplant diarrhoea, organ´s infections and metabolic complications such as post-transplant diabetes mellitus. Also important is the influence of the microorganisms of the gut microbiome on metabolism of immunosuppressants with the production of less effective components and the subsequent necessity of modifying their levels with a higher risk of underdosing and the occurrence of graft rejection. Support of the composition of the gut microbiome in the post-transplantation period in favor of bacteria producing short chain fatty acids (SCFA) is possible by changing of diet with predominance of fiber, the application of probiotics, prebiotics. According to available studies, it can lead to benefits in term of metabolic compensation, to the induction of donor-specific tolerance and many others, with an overall improvement in the quality of patient and graft survival.

Dyslipidemia (DLP) is the most important risk factor for atherosclerotic cardiovascular disease (ASCVD) and, in the context of severe hypertriglyceridemia (TG > 10 mmol/l), a risk factor for the development of acute pancreatitis. The prevalence of DLP is very high, but their control, especially among the patients at highest risk, is often inadequate. When diagnosing DLP, we should always exclude its possible secondary aetiology (e.g. DLP in the context of hypothyroidism, diabetes, ...). Based on the assessment of the overall CV risk (according to SCORE2/SCORE2-OP or according to the comorbidities of the individual), target values for blood lipids, especially LDL-cholesterol, are determined according to the risk category. The basis of the management of DLP in the prevention of ASCVD is dietary and regimen measures, followed by adequate lipid-lowering therapy in indicated cases. As of April 2023, the portfolio of lipid-lowering medication has been expanded to include inclisiran (small interfering RNA against proprotein convertase subtilisin/kexin type 9 (PCSK9)), which is administered directly in cardiologists' and internists' outpatient clinics, ensuring 100% adherence. In severe hypertriglyceridaemia, fibrate monotherapy may be indicated in addition to dietary and regimen measures; if this treatment fails, some patients may be offered lomitapide, volanesorsen or evinacumab as part of clinical trials or specific treatment programmes if very strict indication criteria are met.

Orthostatic intolerance (OI) is defined as a group of diseases which symptoms are typically manifested in a standing position. These symptoms result from cerebral hypoperfusion and disappear in the supine position. We include postural orthostatic intolerance syndrome (POTS), orthostatic hypotension (OH) and vasovagal orthostatic syncope in this group of diseases. Each of them have similar clinical presentation (blurred vision, weakness, dizziness, nausea, headaches, fatigue). However, they vary from each other in biochemical, autonomic and hemodynamic characteristics. The aim of the work is to provide an overview of humoral and non-human markers that are involved in the etiopathogenesis of orthostatic intolerance.

The use of new antidiabetic drugs in clinical practice in the last two decades has completely changed the Type 2 diabetes management. Following the results of new clinical trials, international recommendations for the treatment of diabetes were regularly modified. In the field of Type 1 diabetes, new technologies have appeared, such as smart insulin pens. We can await once weekly insulins and dual GLP-1 and GIP analogues in the near future.

The introduction of point-of-care ultrasonography into practice in internal medicine and subsequently into the educational program for our specialty brought the need to define a curriculum for training in this method. We solve the question of "what to teach" - i.e. what core ultrasound competencies internists should learn for their practice. It is also necessary to define the procedure "how to teach" - the form and content of the education program, what the basic course should contain, and above all how the subsequent training should take place in practice. The third major problem to be solved is "who should teach", i.e. the definition of the requirements for trainers who will lead the training.

In developed countries, diabetes mellitus (DM) is one of the main causes of end stage renal disease (ESRD). In addition, the development of chronic kidney disease (CKD) further increases the already significantly increased cardiovascular (CV) risk in patients with diabetes. Both albuminuria and impaired renal function predict CV disease-related morbidity. The multifactorial pathogenesis of DM-related CKD involves structural, physiological, hemodynamic, and inflammatory processes. Instead of a so-called glucocentric approach, current evidence suggests that a multimodal, interdisciplinary treatment approach is needed to also prevent further progression of CKD and reduce the risk of cardiovascular events. Combined antihypertensive, antihyperglycemic and hypolipidemic therapy is the basis of a comprehensive approach to prevent the progression of diabetic kidney disease. According to recent evidence, adjunctive therapy with the non-steroidal mineralocorticoid receptor antagonist (MRA) finerenone - in addition to the use of an ACE (angiotensin converting enzyme) or AT1 (angiotensin II receptor subtype 1) blocker and an SGLT2 (sodium-glucose cotransporter-2) inhibitor - represents an effective therapeutic tool to improve nephroprotection in CKD. The aim of this review is to provide brief information on this promising pharmacotherapeutic approach to the treatment of diabetic kidney disease.

Pulmonary embolism in classical meaning is a complication of deep vein thrombosis (usually in the leg veins), developing after a part of the thrombus dislodged and got wedged in pulmonary arteries. However, in half of the patients with pulmonary embolism, deep vein thrombosis is not found. One potential explanation is a different, less common location of the thrombus or previous complete embolization of the whole thrombotic mass. Another possibility is pulmonary artery thrombosis in situ, which is a specific clinical entity associated with some typical risk factors. It develops in the place of vascular injury, as a consequence of hypoxia, inflammatory changes, endothelial dysfunction and injury. Pulmonary artery thrombosis in situ can be a complication after lung resection, radiation therapy, chest trauma, in the patients with Behçet´s disease, sickle cell anemia, chronic obstructive pulmonary disease, tuberculosis or covid pneumonia. Pulmonary artery thrombosis in situ may differ from classical pulmonary embolism in prognosis as well as in therapeutic approach.

The pandemic of the disease COVID-19 (COronaVIrus Disease 2019) caused by the SARS-CoV-2 coronavirus (severe acute respiratory syndrome coronavirus 2) resulted in millions of deaths and many patients have chronic consequences after overcoming the acute condition. Several vaccines have been developed in an effort to stop the spread of the virus, but they have potentially serious adverse effects. We present a case report of a patient with acute (myocarditis, exacerbation of bronchial asthma) and long-term (postural orthostatic tachycardia syndrome - POTS) complications after vaccination with the second dose of mRNA vaccine BNT162b2 (Comirnaty®). Treatment consists of regimen measures, numerous pharmacotherapy (metoprolol, ivabradine, corticosteroids, antihistamines, antiphlogistics, bronchodilators) and several nutraceuticals (maritime pine bark extract, quercetin, vitamins, magnesium, phosphatidylcholine). In the discussion, we analyze post-vaccination injury and present a short review of the current literature.
