Proper co-ingestion of oral medications with an appropriate beverage is crucial to ensure their efficacy and safety. However, studies have shown that most patients do not take their medications with water as recommended, but instead use other drinks such as tea, fruit juices, or alcohol. This practice can lead to clinically significant drug interactions. These interactions most commonly arise from the inhibition of transporters such as OATP1A2 and OATP2B1, or the CYP3A4 enzyme, resulting in decreased or increased bioavailability of medications. For example, green tea, grapefruit juice, or orange juice may reduce the absorption of fexofenadine, lisinopril,...

Maculopathies are a diverse group of diseases that affect the central area of the retina, the yellow spot - macula lutea, which is responsible for central vision. If this part of the retina is damaged by any disease, visual acuity often deteriorates to the point of practical blindness. The macula is a very specific part of the retina from a histoanatomical point of view. In the article, we deal with the most common diseases of the macula, age-related macular degeneration, diabetic macular edema and central serous chorioretinopathy. We also mention other causes of maculopathies such as genetic, vascular, hematological diseases, paraneoplastic syndromes...

Plant-based diets are gaining popularity due to health, environmental and ethical factors, and an increasingly broad segment of the Czech population is adopting them. Evidence shows that a well-planned plant-based diet can offer substantial health benefits, especially in preventing non-communicable diseases, and can be appropriate across all life stages with adequate supplementation. Poorly planned plant-based diets, however, may pose nutritional risks, particularly for vulnerable groups such as children and pregnant women. Recent position statements increasingly recognise plant-based diets as suitable, while emphasising the need for supervision in...

This case report highlights the cardiovascular risks associated with the use of anabolic androgenic steroids (AAS) through the example of a previously healthy male without known risk factors for ischemic heart disease (IHD). Chronic AAS use led to the development of heart failure with reduced ejection fraction (HFrEF) due to IHD, complicated by recurrent arrhythmias and requiring cardiac resynchronization therapy with defibrillator (CRT-D). The case underscores the importance of early detection of risky behavior, the need for interdisciplinary care, and education of the target population.

Cataract - lens opacity, is defined as clouding of the crystalline lens resulting in its refractive index change and subsequent decrease in visual acuity. The development of senile cataract is multifactorial, involving both preventable and non-preventable factors. Genetic predisposition may increase the vulnerability of the lens to exogenous cataractogenic influences. However, adherence to a healthy lifestyle can partly compensate for this susceptibility. In cataract prevention, it is important to identify hereditary risks based on family history, whilst reducing modifiable lifestyle-related risk factors is essential.

One of the fundamental diagnostic methods for monitoring disorders of bone metabolism is the measurement of bone mineral density using dual-energy X-ray absorptiometry. This method allows the determination of bone mineral content at key diagnostic sites, specifically the lumbar spine and the proximal femur, and in some cases, the distal forearm. It is a rapid, non-invasive, and well-standardized technique that uses a global reference database for interpreting results. Despite its apparent simplicity, the measurement requires great care and proper execution. The results can be easily compromised by incorrect measurement procedures or improper interpretation....

Sudden cardiac death (SCD) in individuals under 50 years of age is caused in a significant percentage by hereditary cardiovascular disease. Identification of these cases, post-mortem genetic testing and family cascade screening is the first step towards primary prevention of sudden death in relatives at risk and requires multidisciplinary and multicentric care. Finding a certain hereditary cause of sudden death is generally possible in about 20 % of cases, however, in families with a positive history of sudden death or heart failure and/or malignant arrhythmias, genetic testing is successful in up to half of the families. In the Czech Republic, a...

The immune system provides a balance between a defensive response to pathogens and tolerance to harmless stimuli. Disturbances in this balance lead to immunodeficiency, autoimmunity, allergies, or cancer. Recurrent respiratory infections are a frequent problem in clinical practice, especially among general practitioners. Their cause tends to be multifactorial - from anatomical anomalies to allergies, mucosal immunity disorders, and lifestyle errors. Mucosal immunity plays a key role in airway defense and its weakening leads to increased morbidity. The microbiota also plays an important role, the balance of which is often disturbed by inappropriate...

Acute myocardial infarction has several typical manifestations that lead to further examinations necessary to confirm or exclude it. Even the lay population is educated about these manifestations. However, very often the manifestations of infarction are not typical. However, even patients without characteristic pain should not escape correct and early diagnosis. An infarction should therefore be considered even in the case of atypical pain, dyspnoea itself, nausea to vomiting, sweating attacks, palpitations, sudden general weakness to syncope, unclear anxiety, and restlessness, stroke or transient ischemic attack, sudden confusion to delirium, manifestations...

Obstructive sleep apnoea (OSA) is an under-recognised complication of type 2 diabetes mellitus (T2DM). The aim of this study was to identify a simple BMI threshold that justifies OSA screening in obese men with T2DM. This cross-sectional study enrolled 135 men, all of whom underwent valid home cardiorespiratory polygraphy (HSAT). Any OSA (apnoea–hypopnoea index, AHI ≥ 5 events·h-1) was present in 73 % of participants; BMI emerged as the primary predictor A BMI ≥ 30 kg·m-2 yielded 71 % sensitivity for detecting moderate-to-severe OSA (AHI ≥ 15 events·h-1). We therefore recommend routine OSA screening...
