Introduction: Obesity is a chronic, multifactorial disease that leads to many complications. Many methods of treating obesity are available, but they are often not effective enough. Due to the strong connection between psychological factors and the development of obesity, it can be useful to include mindfulness training in treatment. The aim of this study: Summarize current knowledge on the effectiveness of mindfulness training in the treatment of obesity and evaluate the effect of mindfulness on weight loss. Material and method: The review includes publications published in 2012-2022. The search of publications in the Pubmed database was carried out using the following keywords: mindful eating, mindfulness, weight loss, obesity. Description of the stage of the knowledge: The use of mindfulness techniques in the treatment of eating disorders is becoming more popular. A growing number of studies evaluating the effects of mindfulness on weight loss are emerging, but the results are inconclusive. Mindfulness training is effective in improving eating habits and promoting lifestyle changes. Mindfulness training combined with behavioral treatments for obesity has positive effects on weight loss. Summary: Research shows that mindfulness training may be a promising intervention in obesity treatment because it increases self-awareness and promotes lifestyle changes. However, more research is needed to assess the long-term effectiveness of mindfulness for weight control.

Introduction Cancer is one of the leading causes of death worldwide. The molecular characterization of solid tumors has provided significant advances in oncology, and genome profiling using circulating tumor DNA (ctDNA) has helped improve the quality of medical care for patients with cancer. Liquid biopsy is a diagnostic molecular test to demonstrate the presence of circulating tumor DNA or circulating tumor cells released from primary or metastatic solid tumors. In addition, the minimally invasive nature of the liquid biopsy enables quick verification of the grade of malignancy. Observation of ctDNA in blood tests is of great importance at the treatment stage, it allows to determine resistance to the applied treatment, response to therapy and to predict relapse before it occurs. Aim of the study The aim of this review is to present information on the use of circulating tumor DNA together with circulating tumor cells in oncological diagnostics. Materials and methods The work was created based on the PubMed database. Articles were searched in English using the following keywords: ctDNA, CTC, cfDNA. Results Currently, ctDNA analysis is an alternative to traditional molecular diagnostics of cancer tissue, assessment of the effectiveness of therapy, monitoring of tumor dynamics, monitoring of progression and predicting recurrence. Summary There are not many diagnostic methods for detecting ctDNA. Due to the short length of the fragments and the low content in the samples, ctDNA analysis requires more sensitive techniques to ensure its reliability compared to methods used in solid tissue biopsies. Existing techniques of ctDNA analysis focus mainly on the identification of mutations in advanced stages of cancer, less often on early diagnosis.

The dynamic development of trauma-orthopedic surgery and accompanying material technology has led in recent years to the need for close cooperation between researchers in these fields. In a short time, thanks to the cooperation of engineers and doctors, the general approach to the method of bone anastomosis has changed significantly. The need to optimize the effects of treatment, i.e. to quickly recovery, reduce the number of postoperative complications, reduce the number of reoperations, and reduce the costs of procedures and treatment used has resulted in the development of many new technologies that have set trends in modern traumatology. The widespread use of LCP (Locking compression plate) and locking screws, the development of polymers and biopolymers with a modified chemical structure, a significant improvement in the biocompatibility and cytocompatibility of the materials used, and the implementation of products with significant micro-roughness that improve osseointegration are the well-known and commonly used effects of this cooperation today . Materials science related to orthopedics is an extremely complex and multi-threaded field. Its continuous development requires a periodic summary of the results and development directions provided, which allows faster evaluation and interpretation by researchers. The purpose of the following work is to summarize the latest research on materials and methods used in osteosynthesis in a legible way for potential recipients of this information from various fields.

Introduction and purpose: The sternum is one of the bones that build up the anterior chest wall. It consists of three parts: manubrium, body and xiphoid process. It has been observed that this bone exhibits sexual dimorphism, which can be used in many fields of science. The aim of the study was to find morphological parameters showing sexual dimorphism that allow unambiguous sex identification. Material and method: 240 patients (140 women and 100 men) underwent chest CT and the following measurements were taken: angle of the sternum, length of the manubrium, body and xiphoid process, sum of the length of the manubrium and body, total length of the sternum. The thickness of all three parts of it and the width of the manubrium and body were also measured. Statistical analyses were performed using the Mann-Whitney "U" test. Values of p < 0. 05 were considered statistically significant. Results: The results of all statistical analyses did not show statistical significance as a basis for the definitive determination of gender. However, some trends between the sexes have been observed, but these cannot be regarded as universal principles of gender identification. Conclusions: There is a need for further researches on finding metric parameters of the sternum allowing gender identification, carried out on large population groups. To achieve this goal, the results of imaging tests, which are often used in diagnostics, including post-mortem examinations - Vitropsy, may be useful.

Introduction Knee pain in the pediatric population is a very common health issue in family doctor practice and its cause is not always obvious and easy to determine. It is important to remember that knee pain can also occur as a projection of the obturator nerve conducting signals from the hip joint. During physical examination the hip joint should be also carefully examined. Diagnostic imaging such as radiographs are helpful in evaluating bone parts, whereas ultrasonography and MRI can reveal pathology in periarticular soft tissue. Laboratory tests can help to rule out a septic process and reveal other associated conditions. The aim The aim of this work was to analyze the patient’s case of transient synovitis of the hip manifested by knee pain and discuss other hip joint causes of knee pain in the pediatric population. Case report An individual case report of the five-year-old male patient suffered from non-traumatic knee pain and inability to walk with analysis of undertaken diagnostic and treatment management. Results The patient was correctly diagnosed with transient synovitis of the hip joint and successfully treated due to a thorough physical examination and right diagnostic tests carried out by the emergency physician. Conclusions In every case of non-traumatic knee pain, hip pathology should be always ruled out. Carefully performed physical examination, basic laboratory tests and imagining allow practitioners to make the right diagnosis.

Introduction and purpose: Pulmonary embolism (PE) is one of the leading causes of death worldwide. There are many factors that increase the risk of its occurence. High costs of treatment, non-specific symptoms and high mortality of the disease determine the further search for new methods of treatment and diagnostics. The aim of the study is to determine the incidence of PE in patients after fracture of the proximal end of the humerus. Materials and methods: A literature search was conducted in the PubMed MEDLINE database of medical publications using the following keywords: pulmonary embolism, deep vein thrombosis, proximal humerus fracture. Results: Among the found articles, 4 original papers describing the problems of pulmonary embolism after fractures of the proximal end of the humerus were qualified for further analysis. The incidence of PE after this type of fracture is rare and ranges from 1.3% to 5.1%. Moreover, PE was not the cause of death of any patient in the analyzed literature. Conclusion: The need for further randomized controlled trials on a large group of patients operated with the same technique was demonstrated, including subgroups with and without antithrombotic chemoprophylaxis.
