The active development of technology since the middle of the 20th century has changed the requirements for education in view of the demand for knowledge-intensive specialties. The current approach is focused on the intersubjectivity and complexity of problem solving, the project organization of training and the practical orientation of learning courses. The training of specialists capable of solving qualitatively new tasks is possible only in a special environment where personal and professional competencies are formed. The transformation of education in medicine has led to the active integration of research and clinical experience. A significant impetus for the transition to a new level is provided by the development of cognitive competencies, critical thinking, which is closely interrelated with evidence-based medicine. Novel training programs make it possible to receive research, management, entrepreneurial and communication competencies inaddition to classical clinical education. At present, the future belongs to interdisciplinary teams based on developed clusters.

Functional diseases of the gastrointestinal tract cause significant damage to the health care system. Their frequent combination in the same patient with the migration of clinical symptoms throughout the digestive tube is accompanied by continuous exacerbations, refractory to the therapy and severe psychosocial disorders. This review provides data on the main etiopathogenetic factors, clinical manifestations, course features and management tactics for patients with overlapping for the most common functional diseases of the gastrointestinal tract.

Cardiovascular diseases remain a heavy socioeconomic burden in the modern world, claiming up to four million lives annually, including one million of the Russian population. Most often, cardiovascular mortality is associated with chronic coronary heart disease and its complications. Despite the progress in the treatment of acute coronary syndrome in the acute disease phase, the problem of recurrent coronary events and associated adequate rehabilitation remains unresolved. Modern Russian and European recommendations for cardiovascular rehabilitation present the main directions of secondary prevention of myocardial infarction, which summarize the global and Russian evidence-based medicine data on the problem and are based on the principles of phasing, continuity, succession, and multidisciplinary approach to the patient management. This review focuses on the problems and shortcomings of secondary prevention and cardiac rehabilitation at the patient, doctor, and healthcare system levels. In addition, contemporary approaches to their elimination are described. The necessity and importance of individual training and informing patients and the formation of their sustainable commitment to a healthy lifestyle and therapeutic and preventive measures prescribed by modern guidelines on this issue are emphasized.

Placenta accreta spectrum (PAS) and placenta previa (PP) are severe obstetric disorders associated with high maternal and perinatal morbidity. Early diagnosis of both conditions remains challenging, particularly in cases with subtle imaging findings. This study was aimed to evaluate the diagnostic value of first-trimester maternal serum levels of pregnancy-associated plasma protein-A (PAPP-A) and free beta subunit of human chorionic gonadotropin (β-hCG) in predicting PAS and PP. In this retrospective case–control study, a total of 100 pregnant women were included: 36 with PAS, 32 with PP, and 32 healthy controls. Serum levels were measured at 11–13⁶ weeks of gestation. Both biomarkers were significantly altered in pathological groups compared to controls: PAPP-A was lower in PP (3.04 [1.42–4.52] IU/L) and PAS (3.63 [2.51–5.39] IU/L) vs. controls (5.34 [3.72–8.41] IU/L; p < 0.001), while β-hCG was higher in PP (45.4 [40.1–54.9] IU/L) and PAS (51.4 [32.3–74.8] IU/L) vs. controls (33.5 [22.7–54.1] IU/L; p = 0.044 and p < 0.001, respectively). ROC analysis demonstrated that combined biomarker modeling improved diagnostic accuracy over single-marker use, with AUCs reaching 0.85 (sensitivity 85.2%, specificity 72%) for PAS and 0.88 (sensitivity 100%, specificity 72%) for PP. These findings support the integration of biochemical screening into first-trimester risk assessment protocols. Incorporating maternal serum biomarkers may enhance early identification of high-risk pregnancies, allow timely referral to specialized care, and reduce adverse outcomes. Further prospective studies are warranted to validate the utility of this dual-marker approach across diverse populations and clinical settings.

The prevalence of cholelithiasis, its close pathogenetic connection with metabolic syndrome, high frequency of surgical intervention, significant economic losses put forward this comorbid pathology in a number of leading problems of modern clinical medicine. The factors associated with the metabolic syndrome not only increase the risk of developing cholelithiasis, but also form the basis of non-drug and drug therapy. Metabolic syndrome often determines the occurrence of three common and potentially life-threatening complications of cholelithiasis: acute cholecystitis, acute cholangitis and biliary pancreatitis. Therefore, the solution of this problem is associated with the need for early detection of additional risk factors for cholelithiasis, optimization of the early diagnostic and prognostic model of existing multi-organ pathology with the aim of reducing the progression of the disease and its complications. The data obtained in recent years on the human genome with metabolic syndrome and cholelithiasis make it possible to predict the development of comorbid pathology and to fully ensure the effectiveness of primary prevention.

This study addresses the cervical part of the vertebral column. Clinical pictures of dystrophic diseases of the cervical part of the vertebral column do not always correspond only to the morphological changes—they may be represented by connective tissue formation and nerve and vessel compression. To find out the possible reason, this morphometric study of the cervical part of the vertebral column in 40 cadavers was performed. CT scans were performed on 17 cadaveric material specimens. A total of 12 histological samples of connective tissue structures located in intervertebral canals (IC) were studied. One such formation, an intracanal ligament (IL) located in the IC, was found. Today, there is no term “intervertebral canal”, nor is there a detailed description of the intervertebral canal in the cervical part of the vertebral column. Cervical intervertebral canals make up five pairs in segments C2–C7. On cadavers, the IC lateral and medial apertures were 0.9–1.5 cm and 0.5–0.9 cm, correspondingly. According to our histological study, the connective tissue structures in the IC are ligaments—IL. According to the presence of these ligaments, ICs were classified into three types. Complete regional anatomy characterization of the IC of the cervical part of the vertebral column with a description of its constituent anatomical elements was provided. The findings demonstrate the need to include the terms “intervertebral canal” and “intervertebral ligament” in the Terminologia anatomica.
