The 10th McMaster International Review Course in Internal Medicine (MIRCIM 2025), held in Kraków, Poland, confirmed its status as a high-impact scientific forum promoting evidence-based medical practice. With over 100 speakers from more than 40 countries, MIRCIM fostered multidisciplinary discussions on pressing topics in cardiology, rheumatology, pulmonology, and digital health.
The cardiology section focused on current evidence regarding angina and ischemia with non-obstructive coronary arteries, tailored oxygen therapy strategies in non-hypoxemic patients, the role of complete revascularization post-ST-elevation myocardial infarction, the impact of iron deficiency in heart failure, and perioperative cardiovascular risk management in non-cardiac surgical patients.
The rheumatology track emphasized stratified, biomarker-guided treatment strategies for rheumatoid arthritis, systemic lupus erythematosus, (аnti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis, calcium pyrophosphate deposition disease, fibromyalgia, and adult-onset J. F. Still’s disease. These strategies involve integration of phenotypic, immunologic, and serologic data, as well as imaging findings and reduction of long-term
corticosteroid exposure.
Pulmonology sessions addressed the fundamental lung physiology, updated Global Initiative for Asthma (GINA 2025) guidelines, especially in children under six years old, early detection of lung cancer using low-dose computed tomography, and strategies for perioperative pulmonary complication prevention.
The gastroenterology section focused on several key topics of contemporary clinical relevance. The management of diverticular disease was discussed with particular emphasis on current therapeutic approaches. The treatment of irritable bowel syndrome (IBS) was addressed in detail, with a symptom-based and comorbidity-oriented management
strategy highlighted. The section also explored the prevention of gastrointestinal cancers, analyzing various cancer prevention strategies and emphasizing the implementation of evidence-based methods into clinical practice.
Additionally, the current management of metabolic-associated steatotic liver disease (MASLD) was reviewed in accordance with the latest 2024 European Association for the Study of the Liver (EASL) - European Associationm for the Study of Diabetes) (EASD) - European Association for the Study of Obesity (EASO) guidelines, with a focus on therapeutic interventions targeting metabolic dysfunction-associated steatotic liver disease.
The session on artificial intelligence in medicine explored the current applications and limitations of generative language models such as Generative Pre-trained Transformer (GPT) in medical decision-making, telemedicine, education, and public health awareness. Benefits such as enhanced access to knowledge and reduced clinical burnout were noted, along with necessary precautions in clinical implementation.
MIRCIM 2025 once again affirmed its position as a key platform for advancing interdisciplinary medical knowledge, fostering international cooperation, and enhancing evidence-based healthcare delivery in both global and local contexts.

Introduction. The problem of osteoporosis (OP) has become an epidemic unprecedented in its scale. Numerous studies of various aspects of OP leave out men with a history of gastric resection (GR) as a result of complicated peptic ulcer disease (PUD). Therefore, a detailed characteristics of clinical parameters and hormonal and metabolic homeostasis in men with postgastric resection disease (PGRD) and comorbid OP will allow the improvement of the treatment and prevention of osteodeficiency conditions in this category of patients.

The aim of the study. To characterize clinical parameters and hormonal and metabolic homeostasis in men with postgastric resection disease and comorbid osteoporosis.

Materials and methods. 164 men with PGRD and comorbid OP were examined with preliminary random stratification by the presence of a history of five or more years of GR surgery as a result of complicated PUD. In addition to routine examinations, hormonal homeostasis was studied by the effect of hormones on protein metabolism: anabolic (growth hormone, parathyroid hormone, gastrin, and testosterone) and catabolic (triiodothyronine, thyroxine, glucagon, and cortisol) hormones and cyclic nucleotides. Plasma electrolytes and protein profile were also analyzed.

Results. It was established that the vast majority of patients who underwent the surgery with PGRD and comorbid OP have clinical signs of calcium metabolism disorders. They had significant abnormalities in hormonal and metabolic homeostasis manifested by dyshormonemia, dyselectrolytemia and dysproteinemia. We believe that these scientific facts will help to improve the treatment and prevention of secondary osteoporosis complications in this category of patients.

Conclusions. Among the clinical parameters in men with PGRD and comorbid OP, bone pain and muscle cramps prevailed. Hormonal homeostasis was characterized by dyshormonemia with a significant decrease in almost all studied anabolic hormones and an increase in almost all studied catabolic hormones. Deviations in metabolic homeostasis were manifested by dyselectrolytemia (hypophosphatemia, hypomagnesemia, decreased ionized calcium) and dysproteinemia (hypoalbuminemia, hyper-a₁-globulinemia, hyper-β-globulinemia, sharply reduced glycoproteins).
