Full textAbstract:
Background: Osteoporosis is highly prevalent in postmenopausal women and may result in fractures and disabilities. Total thyroidectomy has also been associated with loss of bone mass. The aim of this cross-sectional study was to evaluate associations among nutritional status, skeletal muscle index and markers of bone turnover to bone mineral density in postmenopausal women who had undergone total thyroidectomy. Methods: Fifty postmenopausal women who had undergone total thyroidectomy were included. Body composition was measured using dual-energy X-ray absorptiometry (DXA). The Geriatric Nutritional Risk Index (GNRI) was calculated using baseline body weight and serum albumin level. Skeletal muscle mass index was calculated as the appendicular skeletal muscle mass (ASM) divided by the height squared and assessed using DXA. Results. Multivariate stepwise linear regression analysis showed that a low GNRI was significantly associated with low lumbar spine bone mineral density (BMD) and T-score, and that a low ASM/height2 was significantly associated with low femoral neck BMD and T-score. A low vitamin D level was significantly associated with low femoral neck BMD and T-score and low total hip BMD and T-score. A high bone alkaline phosphatase (ALP) level was significantly associated with low femoral neck T-score and low total hip BMD and T-score. A low insulin-like growth factor-1 (IGF-1) was significantly associated with low total hip BMD and T-score. Conclusion: In the postmenopausal women who had undergone total thyroidectomy in this study, BMD was positively associated with GNRI, skeletal muscle mass index, and levels of vitamin D and serum IGF-1, and inversely associated with bone ALP level. Nutritional status, skeletal muscle mass index and bone turnover biomarkers can be used to early identify patients with a high risk of osteoporosis in this high-risk group.

Full textAbstract:
We investigated the significance of the single-legged hop test to the anterior cruciate ligament-reconstructed knee as it specifically relates to knee muscle strength recovery and residual anterior laxity. The hop test was conducted on 107 patients with unilateral anterior cruciate ligament-reconstructed knees (78 semitendinosus tendon autografts and 29 bone-patellar tendon-bone autografts). Patients were tested an average of 2 years after surgery. Correlation coefficient analyses determined whether the relationship between knee muscle strength recovery and the hop test was invariant across all levels of residual anterior laxity and whether the relationship between residual anterior laxity and the hop test was invariant across levels of quadriceps muscle strength recovery. Furthermore, we examined the effect of graft harvest site on the hop index. Positive correlations were found between the hop index and muscle strength index at all levels of residual anterior laxity (P 0.05), but these correlation coefficients were relatively low. There were no apparent correlations between the hop index and residual anterior laxity at all levels of quadriceps muscle strength recovery. There was no significant difference in the average hop index between the semitendinosus tendon autograft group and the bone-patellar tendon-bone autograft group.

Full textAbstract:
Background: The utility of muscle health for predicting asymptomatic vertebral fracture (VF) is uncertain. We aimed to determine the effects of muscle health on bone quantity and quality in the older adults and to integrate these factors into a predictive model for VF. Methods: We prospectively recruited participants with a body mass index <37 kg/m2. The total lean mass (TLM), appendicular skeletal muscle index, presence of sarcopenia, and bone mineral density were determined by dual-energy X-ray absorptiometry, and bone quality by the trabecular bone score (TBS). VF was diagnosed based on spine radiography. Results: A total of 414 females and 186 males were included; 257 participants had VF. Lower TLM was significantly associated with poorer bone quantity and quality in both males and females. A low TBS (OR: 11.302, p = 0.028) and sarcopenia (Odds ratio (OR): 2.820, p = 0.002) were significant predictors of VF in males, but not bone quantity. Moreover, integrating TBS and sarcopenia into the predictive model improved its performance. Conclusions: Although TLM was associated with bone quantity and quality in both sexes, sarcopenia and a low TBS were significant predictors of asymptomatic VF only in male participants.

Full textAbstract:
This study aimed to investigate the characteristics of skeletal muscle mass, muscle strength, and physical performance among community-dwelling older women. Data were collected from 306 older adults, and the data of 214 older women were included in the final analysis. Participants’ calcaneus bone mass was measured using ultrasonography. Based on their T-scores, participants were divided into the following three groups: normal (T-score > −1), low (−2.5 < T-score ≤ −1), and very low (T-score ≤ −2.5) bone mass. Further, participants’ skeletal muscle mass, muscle strength (grip and knee extension strength), and physical performance [gait speed and timed up and go (TUG)] were measured. Arm skeletal muscle index (SMI, skeletal muscle mass/height2), leg SMI, and appendicular SMI in the very low bone mass group were low compared to those of the low bone mass group (p = 0.034, p = 0.011, and p = 0.009, respectively). Grip and knee extension strength, gait speed, and TUG were not significantly different between the groups. These findings suggest that older women with low bone density had decreased skeletal muscle mass. Therefore, maintaining or improving skeletal muscle mass may prevent low bone mass.

Full textAbstract:
The purpose of this study was to examine associations among bone mineral density, osteopenia/osteoporosis, body mass index (BMI), and body composition in patients with heart failure (HF). A total of 119 patients (age = 61 ± 12 years, 65% male) underwent dual-energy X-ray absorptiometry scans to determine bone mineral density and body composition. In multivariable linear regressions, BMI, relative skeletal muscle index (RSMI), and mineral-free lean mass were positively associated with total body bone mineral density. Mineral-free lean mass was most strongly associated with bone mineral density (β = .398). In multivariable logistic regressions, higher BMI, RSMI, and mineral-free lean mass were associated with lower odds for osteopenia/osteoporosis. Fat mass was not associated with total body bone mineral density or osteopenia/osteoporosis. These results suggest that muscle mass may be the important component of body mass associated with bone mineral density in patients with HF.

Full textAbstract:
This study examines the functional model of bone development in peri-pubertal boys and girls. Specifically, we implemented a mixed-longitudinal design and hierarchical structural models to provide experimental evidence in support of the conceptual functional model of bone development, postulating that the primary mechanical stimulus of bone strength development is muscle force. To this end, we measured radial and tibial bone properties (speed of sound, SOS), isometric grip and knee extensors strength, bone resorption (urinary NTX concentration), body mass index (BMI), somatic maturity (years from peak height velocity) and skeletal maturity (bone age) in 180 children aged 8–16 years. Measurements were repeated 2–4 times over a period of 3 years. The multilevel structural equation modeling of 406 participant-session observations revealed similar results for radial and tibial SOS. Muscle strength (i.e., grip strength for the radial and knee extension for tibial model) and NTX have a significant direct effect on bone SOS (β = 0.29 and −0.18, respectively). Somatic maturity had a direct impact on muscle strength (β = 0.24) and both a direct and indirect effect on bone SOS (total effect, β = 0.30). Physical activity and BMI also had a significant direct impact on bone properties, (β = 0.06 and −0.18, respectively), and an additional significant indirect effect through muscle strength (β = 0.01 and 0.05, respectively) with small differences per bone site and sex. Muscle strength fully mediated the impact of bone age (β = 0.14) while there was no significant effect of energy intake on either muscle strength or bone SOS. In conclusion, our results support the functional model of bone development in that muscle strength and bone metabolism directly affect bone development while the contribution of maturity, physical activity, and other modulators such as BMI, on bone development is additionally modulated through their effect on muscle strength.

Objectives:To study the relationship of indicators of muscle mass, muscle strength and muscle function with bone mineral density (BMD) in men with coronary heart disease (CHD).Methods:79 men aged over 50 years with verified CHD were examined (mean age 63 (57; 66) years).The BMD (g/cm2) and T-criterion (standard deviation) of the femoral neck and lumbar spine (L1-L4) were evaluated using dual-energy x-ray absorptiometry (DXA) on the lunar Prodigy Primo bone densitometer (USA).To assess muscle mass, the total area (cm2) of the lumbar muscles of the axial section at the level of the 3rd lumbar vertebra (L3) was determined using multispiral computed tomography on a 64-slice computer tomograph “Somatom Sensation 64” (Siemens AG Medical Solution, Germany). The ratio of the obtained index of the area of skeletal muscle to the square of the patient’s growth index determined the “musculoskeletal index L3” (SMI). The media considered the threshold value to be 52.4 cm2/m2. Evaluation of muscle strength was performed using a mechanical wrist dynamometer DC-25. Muscle function was examined using a short physical performance battery (SPPB).Results:The data obtained from the results of correlation analysis show that there is a reliable direct correlation between BMD and hand dynamometry indicators (r=0.250; p=0.026 for the right hand and r=0.247; p=0.028 for the left hand), the T-criterion of the femoral neck and hand dynamometry indicators (r=0.245; p=0.030 for the right hand and r=0.242; p=0.032 for the left hand). A similar relationship was established between the BMD of the lumbar vertebra and the parameters of dynamometry (r=0.237; p=0.036 for the right hand and r=0.228; p=0.043 for the left hand) and T-criterion for the lumbar region and dynamometry parameters (r=0.232; p=0.039 for the right hand and r=0.220; p=0.051 for the left hand). There is no significant relationship between densitometry scores and the result of SPPB tests.There was a significant direct relationship between the total SPPB score and the area of skeletal muscle at the L3 level (r=0.249, p=0.026), the total SPPB score and the musculoskeletal index (r=0.233, p=0.039). A similar relationship was established between the result of the chair lift test and the total area of skeletal muscle at the L3 level (r=0.262, p=0.019) and the musculoskeletal index (r=0.220, p=0.050).A significant negative relationship between walking speed and the musculoskeletal index was found (r= -0.260, p=0.021). The relationship between muscle mass and strength could not be traced.Conclusion:A decrease in muscle strength correlates with the severity of bone loss, while a decrease in muscle function correlates with a decrease in muscle mass. The results obtained confirm the probability of common mechanisms in the development of sarcopenia and osteoporosis in patients with CHD.Disclosure of Interests:None declared

Muscularity of lamb carcasses, which is defined as the depth of muscle relative to dimensions of the skeleton (De Boer et al., 1974), is a commercially important trait in many countries. An objective index of muscularity was defined by Purchas et al. (1991) based on the weights of the muscles around a bone and the bone length. Jones et al. (2002) proposed an objective index to assess in vivo the shape of the muscle in the hind leg using X-ray Computed Tomography (CT), which had a phenotypic correlation of 0.63 with dissection measures of muscularity, as described by Purchas et al. (1991).

Full textAbstract:
Patients with chronic respiratory diseases (CRDs) have a disorder in muscle structure and function, but their function increases with physical progress and decreases the risk of general, and muscular weakness are more likely to develop sarcopenia. We randomly selected patients (N = 38) with mean age of 72 ± 1.0 years old men and women elderly with chronic respiratory diseases such as asthma, COPD, bronchiectasis and obesity with dyspnea score ≥ 2 in MRC index. All patients after receiving research information and signing informed consent have gone through performing clinical assessments. They performed femur bone mineral density (FBMD) and ultrasound on the rectus femoris muscle mid-tight cross-sectional area (RFMTCSA) in the quadriceps muscle. The significant changes in BMI were seen in all patients, pre-rehabilitation, BMI = 30 ± 1.06 kg/m2 and post-rehabilitation, BMI = 29 ± 1.00 kg/m2. In Pearson’s correlation of r = 0.607 between T-score and Z-score in FBMD and RFMTCSA in pre-rehabilitation, there is a little bit significant correlation between the variables than in the Pearson’s correlation of r = 0.910 in post-rehabilitation, P < 0.00. Comparing femur bone and rectus femoris muscle parameters as indicators for diagnosis of sarcopenia in chronic respiratory patients, we observed that in rectus femoris muscle, ultrasound is the most effective foot muscle detector.

Full textAbstract:
The scientific work presents a detailed analysis of the 17-19 years young men morphofunctional status screening studies. The young men who took part in the research did not have any pathologies in their health and belonged to the main medical group. To effectively address the goal of the study, a wide range of methods typical of researches in the field of physical culture and sports was used. A total of 34 indicators were studied, including 23 direct measurements. The reliability of the obtained results is confirmed by adequate theoretical substantiation of scientific positions and research apparatus, highly informative and reliable research methods, optimal duration, correctness of processing, analysis and interpretation of the obtained data. The relevance of the chosen topic is confirmed by the results of the study, which were based on knowledge of age anatomy, age physiology, hygiene of physical culture and sports. Analysis of the young men morphological condition individual results in pre-conscription age indicates incomplete formation of the musculoskeletal system, and the circumferential size of the waist and hips, which exceeded physiological norms indicate the presence of excess body weight. There is a significant asymmetry between the results of wrist dynamometry, the difference between the strength of the right hand and the left hand is 6.2 kg. Studies of the body composition revealed that the average group performance of muscle and bone components of the young men aged 17-19 years is below the physiological norm. The range of muscle component values ranges from a minimum of 36.2% to a maximum of 78.7%, indicating sample heterogeneity. Studies of cardiovascular parameters revealed: heart rate at rest, which exceeded the physiological norm in 26.3% of test subjects, signs of bradycardia in 7.6% of test subjects, signs of hypotension were found in 4.7% of test subjects, signs of hypertension were found in 18.4% of test subjects. We found 7.6% of young men with the pulse pressure exceeded the permissible threshold. The vast majority, which is 70.7% of the studied young men of pre-conscription age, had individual results of endurance coefficient in the range of 17-29 s.u., which indicates a weakened activity of the cardiovascular system. Low individual indicators of lung vital capacity are observed at 8.3% of young men, and are in the range of 2.6-2.9 l. 10.1% of young men with individual respiratory rate results significantly higher than the age norm were also found. In the course of the study, we found that only 19.1% of pre-conscription youth had individual results of the hypoxia index which corresponded to the age norm. The individual results of the Rufier test in pre-conscription young men were distributed as follows: 7.9% have above average level of physical working capacity, 37.2% have average level of physical working capacity, 42.3% have satisfactory level, 12.6% have low level of physical working capacity. It should be noted that as a result of the study we did not find any young men who would have a high level of physical capacity.
