(1) Patients on chronic hemodialysis (HD) experience impaired quality of life (QoL). We analyzed HD’s relationship with physical performance, body composition, and muscle strength; (2) QoL was assessed with the Short Form-36, composed of physical (PCS) and mental (MCS) health dimensions. Physical performance was assessed with the Short Physical Performance Battery (SPPB), body composition (lean tissue mass% (LTM%), fat tissue mass% (FTM%), and skeletal muscle mass% (SMM%)) was assessed with bioelectrical impedance, and lower extremity strength was assessed with a handheld dynamometer; and (3) we enrolled 76 patients (27 F, 49 M), age 62.26 ± 12.81 years, HD vintage 28.45 (8.65–77.49) months. Their QoL score was 53.57 (41.07–70.64); their PCS and MCS scores were 52.14 (38.69–65.95) and 63.39 (44.64–76.79) and strongly correlated (p < 0.0001, R = 0.738). QoL correlated positively with SPPB (R = 0.35, p ≤ 0.001), muscle strength (R from 0.21 to 0.41, p < 0.05), and LTM% (R = 0.38, p < 0.001) and negatively with FTM% (R = −0.32, p = 0.006). PCS correlated positively with SPPB (R = 0.42 p < 0.001), muscle strength (R 0.25–0.44, p < 0.05), and LTM% (R = 0.32, p = 0.006) and negatively with FTM% (R = −0.25, p = 0.031). MCS correlated positively with SPPB (R = 0.23, p = 0.047), SMM% (R = 0.25; p = 0.003), and LTM% (R = 0.39, p < 0.001) and negatively with FTM% (R = −0.34; p = 0.003). QoL was unrelated to sex (p = 0.213), age (p = 0.157), HD vintage (p = 0.156), and BMI (p = 0.202); (4) Better physical performance, leaner body composition, and higher muscle strength are associated with better mental and physical QoL in HD.

Introduction: Branched - chain amino acids (BCAAs) are essential components of proteins that play a crucial role in regulating numerous physiological processes in the human body. This article provides a comprehensive analysis of scientific research on BCAAs, including their involvement in metabolism, protein biosynthesis, and the regulation of anabolic processes. We reviewed the supplementation of BCAAs and its impact on sports performance, body composition, and the therapeutic applications of BCAAs Materials and methods: This study is based on medical articles collected from the PubMed database spanning the years 2011-2023. The research was conducted through the analysis of keywords such as "BCAA supplementation", "BCAA metabolism", and "BCAA treatment". Results: The physiology of BCAAs is well understood. The use of oral supplements containing BCAAs does not have a positive impact on muscle hypertrophy, muscle strength, and post-workout muscle soreness in resistance training. However, branched chain amino acids may serve as a safe and effective therapeutic approach in the treatment of liver cirrhosis.

Introduction: Artificial Intelligence (AI), including Large Language Models (LLM), is becoming increasingly significant in the field of medicine. Chat GPT, the most popular tool based on LLM technology, utilizes deep learning techniques. Currently, there is a growing body of research evaluating the potential applications of Chat GPT in medicine, and our study is based on an analysis of review articles from the largest medical database, PubMed. Aim of the study: The primary aim of this study was to conduct a comprehensive analysis of the utilization of Chat GPT in medicine, focusing on identifying its positive and negative aspects as well as limitations. State of Knowledge: Previous studies have demonstrated a rapid improvement in the efficacy of responses provided by Chat GPT. It has the potential to support diagnostics, therapy, patient communication, and medical education, thereby enhancing the quality of healthcare. However, there are certain issues associated with the implementation of this technology in the field of medical sciences, such as concerns regarding data sources, responsibility, and ethics when relying on responses generated by bots. Moreover, evident and concerning algorithmic flaws need to be addressed. Conclusions: Chat GPT, due to its accessibility and continuous improvement, has become one of the greatest hopes for the development of various industries, including medicine. It can be widely used to support educational processes and enhance efficiency in medicine. However, the use of such tools entails numerous challenges and issues, as they still have several drawbacks and limitations, such as ethical considerations and source verification. Further research on the utility of this tool is therefore necessary.

Background/Objectives: Influenza is a viral infection affecting up to 20% of the general population annually. Solid organ transplant recipients have a higher morbidity and mortality risk, as well as a greater likelihood of severe disease complications. Vaccination against the influenza virus is a safe and recommended prophylaxis; however, immunosuppression and high comorbidity burdens impair the immune response. We assessed the efficacy, safety, and humoral response to influenza vaccine in a population of kidney transplant recipients (KTx). Methods: Adult KTx recipients at least 6 months post-KTx were divided into vaccinated (vKTx) and non-vaccinated (nvKTx) groups based on consent for vaccination. The vKTx group received one dose of quadrivalent split virion inactivated vaccine (Vaxigrip Tetra Sanofi Pasteur). Subjective symptoms and side effects were recorded in paper journals. Antibody levels were assessed with ELISA prior to and 3 months following vaccination. Serum creatinine and proteinuria were assessed prior to vaccination as well as 3 and 6 months after. Results: Of 450 recruited KTx recipients, 91 in the vKTx group and 36 in the nvKTx group of comparable age, KTx vintage, and graft function were included in the study. Graft function and proteinuria remained stable in both groups. The vKTx group experienced no severe adverse events. The most common complaints were general malaise (20.5%) and injection site pain (10.3%). Overall infection rates were comparable, yet the vKTx group experienced significantly fewer serious infections (11.4% vs. 32.3%, p = 0.01); the vKTx group showed a greater increase of Influenza A IgM (p = 0.05) and Influenza B IgG (p = 0.01) compared with the nvKTx group. Conclusions: Influenza vaccination prevents severe infections in KTx recipients, with good serological response and no impact on graft function or severe adverse events.

Introduction: Creatine is a non-protein amino acid that is synthesized endogenously mainly in the liver, kidney or pancreas, and also supplied exogenously with food, especially meat. The use of dietary supplements containing creatine is becoming increasingly popular, as evidenced by sales of $400 million per year.

Aim of the study: The aim of our study was to evaluate the potential applications of exogenous creatine with a particular focus on its use in sport. State of Knowledge: Regular use of creatine contributes to water retention in the body as well as muscle hypertrophy. This leads to improved athletic performance, faster recovery as well as a shorter recovery period after injury. The potential use of creatine as an aid in the treatment of depression seems extremely interesting, but these reports require further research. Conclusion: Creatine is currently one of the most popular dietary supplements. Not only is it widely used in sport, where it shows a number of benefits, but research is also underway into its use in medicine.

Introduction: Many wounds are treated surgically. For many years the method itself consisted mainly in cleaning the wounds and bringing its edges closer together, either by strips for closing the wounds or by suturing the wound with classic sutures or staples. Recently, new methods have emerged to support wound healing, which are discussed in this article. Materials and methods: The basis of the work were medical articles collected in the PubMed database. The research was conducted by analyzing key words such as: "surgical treatment of wounds", "new technologies in wounds", "wound healing and new technologies", "dressings in wound treatment", "new methods of accelerating wound healing". Results: In the process of surgical wound treatment the basis is still the closure and connection of the edges of the wounds, which prevents infections, accelerates healing and improves the cosmetic effect. However this is not the final stage of wound healing. Equally important is the subsequent appropriate selection of the dressing - appropriate in terms of its composition of active substances and absorption properties. The choice of the right dressing has a large impact on the final effect and the avoidance of infections or the subsequent appearance of the scar. Now we also have many new technologies to help heal wounds. They help not only to reduce the risk of infection, but also accelerate the healing process and shorten the treatment time.
