Indicators of mineral bone density in male patients with osteoarthritis of knee joint of elderly and old age depending on condition of muscular system

Objective. To evaluate bone mineral density (BMD) indices in elderly and old age male patients with knee osteoarthritis (OA) depending on the state of the muscular system.Subjects and methods. The trial enrolled 32 patients with knee OA. The mean age of the patients was 68.7 (66.1; 70.3) years. The diagnosis of knee OA was established according to the diagnostic criteria of the American College of Rheumatologists (ACR, 1991). For comparative analysis, all patients with knee OA were divided into 3 groups according to muscle condition (EWGSOP, 2010: muscle mass was assessed by multispiral computed tomography, muscle strength was measured using a wrist dynamometer, muscle function was examined using a battery of short tests): the 1st – 9 patients without sarcopenia, the 2nd – 11 patients with presarcopenia, and the 3rd – 12 patients with sarcopenia. BMD was assessed by dual-energy X-ray absorptiometry in the neck and proximal femur as a whole and in the lumbar spine.Results. Osteopenic syndrome in the study cohort was diagnosed in 23 (71,9%) patients: osteopenia – in 19 (59,4%) patients, osteoporosis – in 4 (12,5%). Normal BMD values were observed in 9 (28.1%) patients. Osteopenic syndrome was detected in patients with sarcopenia signifcantly more often compared to patients without sarcopenia (p > 0.05) and with presarcopenia (p = 0.05). BMD indices in patients with sarcopenia in the neck and proximal femur in general were statistically signifcantly lower than in patients without sarcopenia and with presarcopenia (p < 0.05). There was a direct correlation between total skeletal muscle area at the LIII level and densitometric indices of the femoral neck.Conclusions. Sarcopenia is associated with low BMD indices in the neck and proximal femur in general in elderly and senile male patients with knee OA

The influence of antenna gain and beamwidth used in OSSEUS in the screening process for osteoporosis

Applications on electromagnetic waves in the field of biotelemetry have increased in the latest years, being used to prevent, diagnose, and treatment of several diseases. In this context, biotelemetry allows minimally invasive monitoring of the physiologic, improving comfort and patient care and significantly reducing hospital costs. Aiming to assist the mineral bone density classification, through a radio frequency signal (RF), for a later diagnosis of osteoporosis, Osseus was proposed in 2018. This equipment is a combination of the application of techniques and concepts of several areas such as software, electrical, electronic, computational, and biomedical engineering, developed at a low cost, with easy access to the population, and non-invasive. However, when placed on evaluation, potential improvements were identified to increase the stability of Osseus operation. It is proposed the implementation of improvements in the antennas used by Osseus, aiming its miniaturization, improvement in the reception of the RF signal, and better stability of the equipment's operation. Then, two antennas were built, one of which was used as a project for the second, which is an array. The array showed significant improvements in the radiation parameters relevant to the application, being a candidate to replace the antennas currently in use at Osseus.

High protein diet: benefits and risks

The nature of human nutrition has become increasingly important as an effective element in the prevention and treatment of many pathologies, especially obesity, type 2 diabetes and cardiovascular diseases. High protein diets are some of the most popular eating patterns and the Dukan diet has taken the lead in popularity among the diets of this type. An increase of protein in the diet is effective in reducing body weight, primarily due to the loss of adipose tissue, without a significant effect on muscle mass. Another advantage of a high-protein diet is earlier and longer satiety compared to other diets, which makes it comfortable for use. Besides obesity, high protein diets are presumably effective for treating such diseases as nonalcoholic fatty liver disease, diabetes mellitus and cardiovascular diseases However, despite the important advantages, this nutritional model is not universal and is contraindicated in patients with diseases of liver, kidneys and osteoporosis. Besides, the prolonged use of a high protein diet may increase the risks of urolithiasis and reduced mineral bone density even for healthy individuals. Thus, the increase in the proportion of protein in the diet should take place exclusively under the supervision of a physician.

The objective of this review aspects concerned with the natural behavior of birds, the stress suffered when subjected to confinement, the importance of the study of the mineral bone density and the understanding of the causes of osteoporosis and appropriate measures to be taken to mitigate the severity of this disease and contribute to animal welfare. Therefore, the importance of research in the area of bone mineralization, adaptations to the environment and diets with adequate levels of calcium, vitamin D and phosphorus for maintenance of the quality of the bone tissue of birds is seen.

THE INFLUENCE OF EXOCRINE PANCREATIC INSUFFICIENCY IN THE FORMATION OF OSTEOPENIA IN PATIENTS WITH PRIMARY OSTEOARTHRITIS

The aim: Make complex study of bone density in patients with primary osteoarthritis and exocrine pancreatic insufficiency and patients with primary osteoarthritis without exocrine pancreatic insufficiency. Materials and methods: There were examined 140 patients with primary osteoarthritis without exocrine pancreatic insufficiency and combination osteoarthritis and exocrine pancreatic insufficiency. Diagnosis of osteoarthritis was based on diagnostic X-Ray criteria – according to J.H. Kellgren and J.S. Lawrence. The level of exocrine pancreatic insufficiency was based on result of Elisa test. State of mineral bone density was examined by using dual-photon densitometry. Results: It was established that there was a progressive, statistical, significant increase of mineral density of bone tissue in the 1-st group patients with osteoarthritis. Patients in the 2-nd group, with osteoarthritis in the comorbidity with exocrine pancreatic insufficiency, the densitogram rates were statistically significantly lower than in patients in the 1-st group. Conclusions: The changes of bone tissue can be explained by the formation of trophological insufficiency as a result of exocrine pancreatic insufficiency. One of the symptoms of trophic failure is bone and mineral changes, in particular, the decrease of bone density.
