Objective of this paper was the evaluation of changes in the representation of expertise providing care for patients with DM (pDM) in the Czech Republic, based on data analysis from the National Register of Paid Health Services (NRHZS) 2010-2021. In the entire pDM group, the number of patients treated by a diabetologist (DIA) increased from 491,490 (57.0 %) to 537,430 (50.4 %), with a general practitioner (GP) from 27,719 (3.2 %) to 181,330 (17.0 %) and by internist (INT) from 172,918 (20.0 %) to 161,291 (15.1 %). In 2021, 57.9 % DIA, 17 % GP, 12.2 % INT were treated from the group treated with antidiabetics (813,873). In 2021, 84,345 were treated with insulin alone (87.2 % DIA), 129,127 were treated with a combination of insulin and non-insulin antidiabetics; 115,604 (91.6 %) in DIA, 322 (0.3 %) in GP and 7,983 (6.3 %) in INT. 603,331 treated only with non-insulin antidiabetic drugs, of which 281,929 (46.7 %) DIA, 137,744 (22.8 %) GP and 85,273 (14.1 %) INT. For other specialties, 98,385 (16.3 %) persons. 185,838 patients without reported DIA/GP/INT control, of which 80,144 without therapy. The increasing prevalence of DM and changes in reimbursement conditions are reflected in the dynamic development of the distribution of diabetes care by individual specialties.

The tolerable incidence of this complication ranges from 5 to 8 %. The aim of this study was to evaluate the influence of initial risk factors on the incidence of postoperative pneumonia in patients undergoing lung resection for NSCLC. A retrospective cohort study was conducted at the University Hospital Ostrava between January 1, 2016, and December 31, 2022. All adult patients who underwent pulmonary lobectomy for primary NSCLC during the study period were included in the study. A total of 350 patients were included in the study. The incidence of postoperative pneumonia was 10.9%. Analysis of baseline risk factors did not show a statistically significant association with the incidence of this complication. The only statistically significant finding was a longer hospital stay in patients with postoperative pneumonia. The risk of postoperative pneumonia in patients undergoing lung resection for non-small cell lung cancer cannot be clearly explained by the initial risk factors examined alone. The complex nature of this risk also requires a comprehensive approach to prevention, including both patient-centred measures and improved postoperative care.

As telemedicine evolves, its ethical dimensions play an increasingly pivotal role in balancing the benefits of advanced technologies, ensuring responsible healthcare practices within telemedicine environments, and safeguarding patient rights. Healthcare providers, patients, policymakers, and technology developers involved in telemedicine encounter numerous ethical challenges that need to be addressed. Key ethical topics include prioritizing the protection of patient rights and privacy, which entails ensuring equitable access to remote healthcare services and maintaining the doctor-patient relationship in virtual settings. Additional areas of focus encompass data security concerns and the quality of healthcare delivery, underscoring the importance of upholding ethical standards in the digital realm. A critical examination of these ethical dimensions highlights the necessity of establishing binding ethical guidelines and legal regulations. These measures could assist stakeholders in formulating effective strategies and methodologies to navigate the complex telemedicine landscape, ensuring adherence to the highest ethical standards and promoting patient welfare. A balanced approach to telemedicine ethics should integrate the benefits of telemedicine with proactive measures to address emerging ethical challenges and should be grounded in a well-prepared and respected ethical framework.

In individuals over 80 years of age, we can diagnose the presence of monoclonal immunoglobulin (MIg) in up to 10 % of cases. Not only malignant diseases such as multiple myeloma (MM), but also benign forms such as MGUS (monoclonal gammopathy of undetermined significance) can lead to renal involvement. The light chains of immunoglobulins (LC) are the most damaging to the kidneys, as they are freely filtered into the urine due to their molecular weight. Detection of MIg relies mainly on a combination of immunofixation electrophoresis of serum (IELFO) and urine and determination of free light chains (FLC) of kappa and lambda and their ratio (κ/λ) in serum. The combination of these tests will detect the presence of MIg with 99 % sensitivity. Renal damage in MG may be caused by direct deposition of MIg in the glomeruli (e.g. AL amyloidosis, LC deposition disease) or tubules (in the distal tubule as a myeloma kidney or in the proximal tubule as Fanconi syndrome or proximal tubulopathy). Typical urinary findings in these diseases are moderate or severe proteinuria or nephrotic syndrome. Acute kidney injury (AKI) can be expected especially when serum FLC is >500 mg/l. Renal biopsy is crucial to establish an accurate diagnosis and thus initiate the correct treatment. Treatment of these types of renal damage involves the same treatment regimens used in the treatment of MM, including proteasome inhibitors or daratumumab.

It was originally designed for genetic diseases that, because of their prevalence, were a group known as rare diseases. Gene therapy has so far been applied in children to act before the disease development. These new treatments have also begun to be applied for common diseases such as metabolic disorders (e. g. diabetes) and even for those that are increasingly affecting us, such as various malignancies and diseases of the central nervous system (e. g. Alzheimer's disease). The targets targeted by GT are genes, where pathogenic alterations in the form of pathogenic variants (formerly mutations) induce phenotypic disorders, and our aim is either to knock them out of function (e. g. haemoglobinopathies) or to replace them with genes with normal function, which we introduce into the genome using one of the appropriate vectors, such as viruses or liposomes. The process of GT can take place directly inside the patient's body (in vivo) or outside the body on isolated cells (ex vivo), which are usually stem cells (iPSCs, induced pluripotent stem cell). After treatment, these cells are returned to the patient's body to fulfil their "destiny". In a broader sense, GT can target the product of gene transcription, which is the messenger RNA, or the end product of gene function, such as functional proteins (eg. cystic fibrosis). Any of these approaches have been used successfully in various diseases, depending on their availability, which is determined, among other things, by the costs associated with GT or the accessibility of the target tissue. Ultimately, it is not only the validation of the efficacy and safety of GT, but also economic reasons that determine why GT has been slow to develop and is mostly undertaken only by large and wealthy institutions. Another decisive factor is that from initial experimental work through clinical trials, the whole process of its development normally takes up to a decade.

WHO Europe has organized surveillance of childhood obesity (Childhood Obesity Surveillance Initiative, COSI) since 2008, which observed the prevalence of overweight and obesity of 6-9-year-old children is followed during this study and proved this result. The study Children's Health 2016 showed that after a period of the global increase of obesity until 2011, there was in the Czech Republic a period of certain stabilization, in which there weren´t major changes in weight. Unfortunately, the covid pandemic changed this trend and the current data from 2021 showed in the Czech Republic a serious increase in childhood obesity. For these children will be necessary to use a new type of treatment of obesity as a surgical and pharmacological specific treatment.

Each symptom could be presented alone or commonly in combination with other symptoms. The acute climacteric syndrome is induced by decrease and fluctuations of estrogen and neurosteroids levels. Therapy could be focused on hormone replacement. Changes of quality of life and especially effects of the therapy could be measured by standardized questionaries.

Women who had their first child before their 20th birthday, a pattern of reproductive behaviour common among generations of women before 1989, have an earlier onset of menopause than older first-time mothers. Conversely, the effect of higher age at first birth (35 years or more) on the delay of menopause has not been proved. However, this issue requires further investigation, as the sample analysed suggests certain tendencies. A larger sample size would be needed to make a conclusive finding.

The results show that 27% of women and men in their forties declare they have experienced a time when they were trying to get pregnant but did not conceive within at least 12 months. In the general population of reproductive age, one in five declares experience with methods helping to get pregnant. Methods that do not require a doctor's visit are the most frequently used (one in ten declare monitoring ovulation), and 5% of the general population have experience of ART. Among those who have experienced some period of infertility, the experience of methods to assist conception is significantly higher (3/4 of men and 2/3 of women), and the use of medically assisted reproduction is also higher (a quarter have experience of taking medication and a quarter of assisted reproduction).

Reproductive plans are predominantly formulated at the threshold of adulthood and only 11 % of women under 25 are unsure of their reproductive plans. In the short term, childbearing is planned with the greatest intensity at the ages of 25-29 and 30-34 (when 47 and 33 % of women plan to have a child, respectively), while for childless women the intensity of planning peaks slightly later, at the ages of 30-34 and 35-39 (planning rates of 54 and 50 %, respectively). Older women are not giving up their desire to pursue their reproductive plans. Despite the health risks associated with motherhood at an older age, 20 % of childless women aged 40-44 plan to have their first child in the next three years or later. In addition to age and the current number of children, short- and long-term reproductive plans also differ by women's education, with college graduates more likely to plan to have (another) child in the short and long term than women with less education. At the same time, short-term plans are influenced by women's partnership status, and in the case of long-term reproductive plans, the influence of perceptions of the long-term impact of the COVID-19 pandemic was observed.

Czechia was unique not only among Eastern European countries, but also worldwide. At the same time the decline in the prevalence of hormonal contraception from a peak of almost 50 % in 2007 to 30 % in 2021 meant a slowing and gradual halt in the further decline in abortions. The results of the GGP 2020-2022 survey in Czechia showed that the lower use of hormonal contraception among women was only partly offset by the increased use of other reliable methods of protection against unintended pregnancy (e.g. condom use). The largest decline in the use of hormonal contraceptives in the form of the pill occurred among the youngest women aged 18-27 years, from 76 to 37 %, which was partly reflected in the more intensive use of condoms (an increase from 21 to 35% in the 18-27 age group), but is worrying, that this age group saw the largest increase in the use of less reliable methods (withdrawal from 11 to 22 % and an increase in the use of the barren days method from 1 to 6 %) and also the largest increase in the proportion of women using neither method (from 7 to 17 %). The lowest proportion of female hormonal pill users was found among female with higher education. However an important finding is that when less reliable methods are used, there is an effort to combine at least two methods. Women have a more important role in determining how to protect themselves from unintended pregnancy.

The...The assessment of the development of fertility and abortion rates over the last three decades shows that Czechia has reached the top position in Europe with a total fertility rate of 1.83 children per woman in 2021. The postponement of fertility to women's older age, which was behind the sharp drop in fertility to 1.1, has been gradually slowed down and halted between 2015 and 2021. In recent years, there has been an increase in fertility rates for women aged 30 and older as well as a balanced increase for women under 30. In the European context Czechia has maintained its position as a country with lower rates of reproductive ageing. The favourable demographic position of Czechia among European countries is also illustrated by the relatively low level of the abortion rate. The postponement of female fertility to older ages has not been accompanied by an increase in the abortion rate among young women, but on the contrary a decline in fertility has been accompanied by a decline in the abortion rate. Given the year-on-year increase in total fertility (from 1.71 in 2020 to 1.83 in 2021), the initial effect of the COVID-19 pandemic on fertility can be assessed positively. However, the subsequent decline to 1.62 in 2022 is already the result of a combination of adverse effects stemming from the consequences of antipandemic measures and worsening economic conditions, to which new security risks associated with the war in Ukraine have subsequently been added. This has created the conditions for a further postponement of fertility until women are older.

These models, including OpenAI's GPT-4, Google's Bard, and Anthropic's Claude, enable more efficient text processing through transformer architecture and attention mechanisms. LLMs can generate coherent texts that are indistinguishable from human-written content. In medicine, they can contribute to the automation of literature reviews, data extraction, and hypothesis formulation. However, ethical concerns arise regarding the quality and integrity of scientific publications and the risk of generating misleading content. This article provides an overview of how LLMs are changing medical writing, the ethical dilemmas they bring, and the possibilities for detecting AI-generated text. It concludes with a focus on the potential future of LLMs in academic publishing and their impact on the medical community.

Diabetic retinopathy, a microvascular complication of diabetes mellitus, often remains unnoticed until patient is facing complications. Artificial intelligence presents a promising solution that can enhance the accessibility of diabetic retinopathy screening for a broader range of patients. The key challenge lies in successfully integrating the solution into clinical practice, a demanding process with multiple phases to ensure the resulting medical device is effective and safe for patient use. Aireen software uses artificial intelligence to perform diabetic retinopathy screening on retinal images captured by optical fundus cameras. The medical device complies with European Medical Device Regulation 2017/745 and was introduced to the market in 2023. Collaboration between physicians and the development team played a crucial role throughout the entire lifecycle of the medical device. Physicians were engaged in defining the intended use of the medical device, risk analysis, data annotation for training and software validation, as well as throughout a clinical trial. A clinical trial was conducted on 1,274 patients with type 1 and type 2 diabetes mellitus, where Aireen medical device achieved a sensitivity of 94.0% and a specificity of 90.7% compared to the reference evaluation. This clinical trial confirmed the potential of Aireen to enhance the availability of diabetic retinopathy screening and early disease detection.

Particularly in radiodiagnostics, according to studies, AI has the potential to enhance accuracy and efficiency. We focus on AI's role in diagnosing pulmonary lesions, which could indicate lung cancer, based on chest X-rays. Despite lower sensitivity in comparison to other methods like chest CT, due to its routine use, X-rays often provide the first detection of lung lesions. We present our deep learning-based solution aimed at improving lung lesion detection, especially during early-stage of illness. We then share results from our previous studies validating this model in two different clinical settings: a general hospital with low prevalence findings and a specialized oncology center. Based on a quantitative comparison with the conclusions of radiologists of different levels of experience, our model achieves high sensitivity, but lower specificity than comparing radiologists. In the context of clinical requirements and AI-assisted diagnostics, the experience and clinical reasoning of the doctor play a crucial role, therefore we currently lean more towards models with higher sensitivity over specificity. Even unlikely suspicions are presented to the doctor. Based on these results, it can be expected that in the future artificial intelligence will play a key role in the field of radiology as a supporting tool for evaluating specialists. To achieve this, it is necessary to solve not only technical but also medical and regulatory aspects. It is crucial to have access to quality and reliable information not only about the benefits but also about the limitations of machine learning and AI in medicine.

Medical imaging techniques are no exception. AI can find application in image acquisition, image processing and augmentation, as well as in the actual interpretation of images. Moreover, within the domain of radiomics, AI can be instrumental in advanced analysis surpassing the capacities of the human eye and experience. While several certified commercial solutions are available, the validation and accumulation of sufficient evidence regarding their positive impact on healthcare is currently constrained. The role of AI presently leans towards being assistive, yet further evolution is anticipated. Risks and disadvantages encompass dependency on computational power, the quality of input data, and their annotation for learning purposes. The transparency of algorithmic functioning is lacking, and issues pertaining to portability may arise. The integration and utilization of AI introduce entirely new ethical and legislative aspects. Predicting the future development of AI in imaging methods is challenging, with a further increase in implementation appearing more probable.

Current technological development contributes to generation of large volumes of data that cannot be evaluated only manually. We describe the process of patient care and its individual parts that can be supported by technology and data analysis methods. There are many successful applications that help in the decision support process, in processing complex multidimensional heterogeneous and/or long-term data. On the other side, failures appear in AI methods applications. In recent years, deep learning became very popular and to a certain extend it delivered promising results. However, it has certain flaws that might lead to misclassification. The correct methodological steps in design and implementation of selected methods to data processing are briefly presented.

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.

The conclusion of the article is neither the form coloscopy nor the form colonoscopy is to be rejected. The final form depends on how the term got into Czech medical terminology - whether directly from Greek or via French (coloscopy) or through English (colonoscopy). As far as the professional-medical discourse is concerned, the article supports those opinions that recommend the unification of the first variant for professional medical practice, i.e. term coloscopy as a direct adaptation of the Greek word. However, regarding common practice in relation to patients, the fact that the term colonoscopy is more frequent and more familiar to users cannot be neglected; therefore, it cannot be rejected.

In contrast to that, postoperative application of negative pressure wound therapy to primarily closed surgical wounds...Negative pressure wound therapy is a generally accepted method of treating septic or secreting wounds. In contrast to that, postoperative application of negative pressure wound therapy to primarily closed surgical wounds is referred to as closed-incision negative-pressure wound therapy (Ci-NPWT). According to available sources, wounds after prophylactic application of Ci-NPWT show lower complication rates, especially wound infections, and dehiscence. The literature confirms that the Ci-NPWT technique improves healing of all surgical wounds, both septic and aseptic.
