Retrospective Study of Nosocomial Infections in the Orthopaedic and Rehabilitation Clinic of the Medical University of Lublin in the Years 2018-2020.

Nosocomial infections appear in patients treated in hospital, which are not the initial cause of admission. A retrospective study concerning nosocomial infections was conducted to provide data about the amount, frequency and types of nosocomial infections in the rehabilitation ward in the Orthopaedics and Rehabilitation Clinic of Lublin. The study was conducted on a group of 49 patients that were admitted or transferred to the ward over a period of 20 months in the years 2018-2020. The patients and therefore the infections were divided by age, sex, time of hospitalization and the underlying disease. The study also provided data about the most frequent infection types in these patients, as well as the most commonly used drugs to treat those infections. The results showed that in fact all of the examined factors have an impact on the frequency of nosocomial infections appearance rates. Furthermore, results in the study showed that factors examined by the study also have an impact on what type of infection was present in these groups of patients.

ß-Hydroxy-ß-Methylbutyrate (HMB) Supplementation Prevents Bone Loss during Pregnancy-Novel Evidence from a Spiny Mouse (Acomys cahirinus) Model.

The aim of this study was to determine the effects of ß-hydroxy-ß-methylbutyrate (HMB) supplementation during pregnancy on postpartum bone tissue quality by assessing changes in trabecular and compact bone as well as in hyaline and epiphyseal cartilage. The experiment was carried out on adult 6-month-old female spiny mice (Acomys cahirinus) divided into three groups: pregnant control (PregCont), pregnant HMB-treated (supplemented with 0.02 g/kg b.w of HMB during the second trimester of pregnancy, PregHMB), and non-pregnant females (NonPreg). Cross-sectional area and cortical index of the femoral mid-shaft, stiffness, and Young modulus were significantly greater in the PregHMB group. Whole-bone mineral density was similar in all groups, and HMB supplementation increased trabecular number. Growth plate cartilage was the thinnest, while the articular cartilage was the thickest in the PregHMB group. HMB supplementation increased the content of proteoglycans in the articular cartilage and the percentage of immature collagen content in metaphyseal trabeculae and compact bone. In summary, dietary HMB supplementation during the second trimester of pregnancy intensifies bone metabolic processes and prevents bone loss during pregnancy.

Structural Changes in Trabecular Bone, Cortical Bone and Hyaline Cartilage as Well as Disturbances in Bone Metabolism and Mineralization in an Animal Model of Secondary Osteoporosis in Clostridium perfringens Infection.

There is no information regarding whether changes in the microbiological balance of the gastrointestinal tract as a result of an infection with Clostridium perfringens influence the development of metabolic bone disorders. The experiment was carried out on male broiler chickens divided into two groups: control (n = 10) and experimental (n = 10). The experimental animals were infected with Clostridium perfringens between 17 and 20 days of age. The animals were euthanized at 42 days of age. The structural parameters of the trabecular bone, cortical bone, and hyaline cartilage as well as the mineralization of the bone were determined. The metabolism of the skeletal system was assessed by determining the levels of bone turnover markers, hormones, and minerals in the blood serum. The results confirm that the disturbed composition of the gastrointestinal microflora has an impact on the mineralization and metabolism of bone tissue, leading to the structural changes in cortical bone, trabecular bone, and hyaline cartilage. On the basis of the obtained results, it can be concluded that changes in the microenvironment of the gastrointestinal tract by infection with C. perfringens may have an impact on the earlier development of osteoporosis.

FAT TISSUE AND SYNTHESIZED BY HER ADIPOKINES AS MARKERS INDICATING THE DEVELOPMENT AND PROGRESS OF OSTEOARTHRITIS.

Arthrosis as osteoarthritis is a global problem that affects more and more people and is associated with severe chronic pain, reduced mobility and, consequently, disability. The etiology of degenerative disease is complex and depends on many factors. However, its course was not fully understood. One of the factors affecting the development of arthrosis is obesity. Obesity is a growing problem. Over the past 30 years, the number of overweight people has almost doubled. In people suffering from obesity, whose body mass index is above 30kg/m2, the risk of developing degenerative changes in articular cartilage is six times higher than the risk of developing this disease in people with normal body weight. Osteoarthritis is detected when the symptoms get worse where the changes are already at some stage. Therefore, a lot of research is currently underway to find suitable biomarkers, which would indicate the potential development of degenerative changes in the future and at the same time the possibility of inhibiting their activity. One of them may be adipokines, which are synthesized by adipose tissue and affect cartilage. In obese people, adipokines may contribute to the inflammation of the low charterer, whichaccompanies both obesity and arthrosis. These compounds can be specific biomarkers to assess the degree of progression and severity of osteoarthritis. The aim: To assess the importance of obesity and adipokines produced by adipose tissue as specific markers of arthrosis.

DISORDERS OF THE INTESTINAL FLORA AND IT IS EFFECT ON SKELETAL SYSTEM DISEASES.

The intestinal microflora plays an important role in the proper functioning of human. It is complex, diverse and dynamic ecosystem that constantly strives to maintain homeostasis throughout the body. The process of acquiring intestinal microflora begins immediately after human birth. Elementary factors that determine the modification of the composition of the microflora are age, sex, diet, lifestyle. Determinate individual composition of the microflora. Microorganisms inhabiting the intestine perform various functions, from metabolic, immune to trophic. Early changes in the intestinal microflora are reflected in the state of human health. Recently, many studies have been carried out confirming the hypothesis that the bacterial flora of the gastrointestinal tract affects the normal metabolism of bone tissue, and disorders in its composition can lead to the appearance of bumps in the processes of physiological remodeling of bone tissue and contribute to the formation of many inflammations. Microorganisms that rot in the digestive tract regulate bone metabolism through three mechanisms: the impact on the immune system, the hormonal system and the impact on the absorption of minerals. Disorders in the microflora of the digestive tract can lead to the development of inflammatory bowel diseases, and as a consequence to the accelerated development of osteoporosis or arthrosis of the joints. The aim: To collect available publications confirming the impact of microflora on the skeletal system.

Nurse's role in geriatric patients rehabilitation with musculoskeletal system diseases.

OBJECTIVE: Introduction: There is the increasing number of elderly patients with motion disabilities who require help and infatuations from nursing stuff. According to the Central Statistic Department (GUS), 25,4% people in Poland is over 60. In 2050 this number will increase to 40%(39,9%). This is very important topic because when the number of old people will increase the geriatric care will be more important. Especially because this is partially covered by nursing team. They should be satisfied and content of the job they do, and they should fulfill the aim they had when they started this profession. The aim: Analysis of nurse's work with patients, nursing procedures evaluation, how this procedure is scored by the nurse, what is the nurse's role in the rehabilitation process. PATIENTS AND METHODS: Material and methods: There were nursing process with geriatric patients analyzed in this article. There were nursing procedures investigated with the opinion of the person who performed this procedure. Role of the nurse in rehabilitation process was and the satisfaction from typical work load was analyzed. RESULTS: Results: Analyzed results showed that there is a deficit in the nurse's knowledge and the lack of the complex care in elderly patient with disabilities. There is lack of the preparation and education program to perform holistic patient care. This includes monitoring, examination and elderly needs. CONCLUSION: Conclusions: The nurse is the first link that helps the patient to understand his disease. The nurse develops therapeutic contact that helps the patient to feel safe and positively react for the introduced treatment.
