Contribution to Knowledge on Bioapatites: Does Mg Level Reflect the Organic Matter and Water Contents of Enamel?

The matter constituting the enamels of four types of organisms was studied. The variability of the ions was presented in molar units. It was proven that the changes in water contents of the enamel are significantly positively related to changes in Mg; inversely, there is also a strong connection with changes in Ca and P, the main components of bioapatite. The variability in the organic matter has the same strong and positive characteristics and is also coupled with changes in Mg contents. Amelogenins in organic matter, which synthesize enamel rods, likely have a role in adjusting the amount of Mg, thus establishing the amount of organic matter and water in the whole enamel; this adjustment occurs through an unknown mechanism. Ca, P, Mg, and Cl ions, as well as organic matter and water, participate in the main circulation cycle of bioapatites. The selection of variations in the composition of bioapatite occurs only along particular trajectories, where the energy of transformation linearly depends on the following factors: changes in the crystallographic d parameter; the increase in the volume, V, of the crystallographic cell; the momentum transfer, which is indirectly expressed by ΔsinΘ value. To our knowledge, these findings are novel in the literature. The obtained results indicate the different chemical and crystallographic affinities of the enamels of selected animals to the human ones. This is essential when animal bioapatites are transformed into dentistic or medical substitutes for the hard tissues. Moreover, the role of Mg is shown to control the amount of water in the apatite and in detecting organic matter in the enamels.

Strontium Ranelate and Strontium Chloride Supplementation Influence on Bone Microarchitecture and Bone Turnover Markers-A Preliminary Study.

Despite strontium ranelate use in osteoporosis management being one of the promising concepts in disease treatment, there is no clear evidence that strontium organic compounds are more effective than inorganic ones. The aim of this study was to compare strontium chlorate and strontium ranelate influence on the mice bone microarchitecture. We investigated whether strontium chlorate (7.532 mmol/L) and strontium ranelate (7.78 mmol/L) solutions fed to healthy SWISS growing mice (n = 42) had an influence on the percent of bone volume (BV/TV), trabecular thickness (Tb.Th), number of trabeculae (Tb.N), and separation between each trabecula (Tb.Sp) in the chosen ROI (region of interest) in the distal metaphysis of the left femurs. The cortical bone surface was examined close to the ROI proximal scan. There was an increase in each examined parameter compared with the control group. There were no statistical differences between strontium ranelate and strontium chlorate parameters. Our study indicates that organic and inorganic strontium compounds similarly affect the bone microarchitecture and strength.

THE EVOLUTION OF TREATMENT AT THE ORTHOPEDICS AND REHABILITATION CLINIC.

OBJECTIVE: Introduction: The last 20 years have been a period of huge changes in Polish healthcare, both in terms of medical progress as well as organization and financing. These changes, and especially the newly introduced queuing systems significantly influenced the changes in the profile of hospital admission. The aim: To analyze changes in the patient profile, causes and time of hospitalization, as well as the waiting time for hospitalization, in 1996-2019 Lublin SPSK4 Orthopedics and Rehabilitation Clinic. PATIENTS AND METHODS: Material and methods: Patients' medical records were analyzed, including qualification cards. The waiting time for admission to the hospital, the time of hospitalization, the cause of hospitalization, gender and the patient's place of residence were analyzed. RESULTS: Results and conclusions: 1. During the 13 years analyzed, the number of hospitalizations increased from 452 to 1387 patients a year. 2. The waiting time for hospitalization increased from an average of 2 months in 1996 to even 2 years (in the case of patients with chronic category) in 2020. 3. The average length of hospitalization changed compared to the level of 1996 (8 weeks) in the case of patients with the early neurological category increased slightly (9 weeks), in the case of other patients - it decreased to 4 weeks, respectively - chronically ill patients, 3 weeks - patients from the systemic and weekly rehabilitation category - orthopedic patients. 4. The scope of the reasons for hospitalization, but also methods of treatment has expanded significantly. 5. Patient demographic profile in the examined aspects (origin, gender) - remained similar.

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.
