High-Intensity Physical Activity with High Serum Vitamin D Levels is Associated with a Low Prevalence of Osteopenia and Osteoporosis: A Population-Based Study

Hydroxyapatite fortified mango mousse: Formulation, characterization, and sensory data evaluation using fuzzy logic

In this experimental study, hydroxyapatite (HAp), as a valuable calcium source, was extracted from discarded goat bone; raw and nano-biogenic powders were prepared through calcination and ultra-sonication. Resultant powders were characterized by using various spectroscopy techniques. As per the findings of atomic absorption spectroscopy, raw and nano-biogenic powders depicted 1439.7 ± 0.12 and 3194.8 ± 0.07 ppm calcium content, respectively. The range of particle size of nano-biogenic and raw powders was 47-139 and 183 nm, respectively. X-ray diffraction (XRD) confirmed crystalline behavior whereas laser-induced breakdown spectroscopy (LIBS)-derived Ca/P-ratio endorsed excellence in nano-biogenic 1.76 against 1.63 in raw powder. In vitro bioavailability of calcium in raw and nano-biogenic powder was ∼36% and ∼39%, respectively. Next, the powders were further used to develop calcium-fortified mango mousse with varied formulations. A maximum overrun of 23.31% was found in the case of "Raw-A," whereas a maximum viscosity of 8489.98 mPa s was found in the case of "Nano-A." Sensory data of mango mousse were obtained by fuzzy logic method, and PCA ranked the Nano-B and Nano-A samples the best in terms of overall acceptability. Meanwhile, the consumer responses toward product likeness and/or dislikeness were recorded by the hedonic scale that endorsed Nano-A and Nano-B formulations as the most preferred samples. PRACTICAL APPLICATION: The revolution in the eating habits of consumers from traditional foods to fast food imposes the development of new products having good nutritional values. Different waste biogenic food sources can provide an acceptable powdered form of ingredients for the development of novel food products. In this regard, the development of novel food products using calcium supplements has gained space in the food industry.

Older adults physically inactive in occupational and commuting domains have a higher risk for osteopenia and osteoporosis: A 12-month prospective study

The relationship between different domains of physical activity (PA) and bone health in older adults needs to be further investigated. We evaluated 379 Brazilian older adults and observed that the risk of osteopenia is higher in older adults who are physically inactive in occupational domain and for osteoporosis the risk is higher in physically inactive in commuting domain and total habitual PA.

PURPOSE

Bone mineral density (BMD) usually decreases with age, and the risk of osteometabolic diseases, such as osteopenia and osteoporosis, increases in older adults. PA is strictly related to BMD. However, the relationship between different domains of PA and bone health in older adults is still unclear, and needs to be further investigated, aiming at the implementation of preventative health measures for this population. Thus, the aim of the current study was to analyze the association between different domains of PA and the risk for osteopenia and osteoporosis in older adults in a 12-month follow-up.

METHODS

Prospective study that included 379 Brazilian community-dwelling older adults, aged ≥ 60 years (70 ± 7 years, 69% women). Areal bone mineral density (aBMD) total, proximal femur, and lumbar spine were measured by dual energy X-ray absorptiometry (DXA), and PA was self-reported. Binary logistic regression analysis and 95%CI were used to analyze the association between the practice of PA in different domains (at baseline and follow-up) and risk for osteopenia and osteoporosis (follow-up).

RESULTS

The risk for osteopenia (total proximal femur or lumbar spine) is higher in older adults who are physically inactive in the occupational domain (OR:3.25; 95%CI:1.24-8.55). In addition, older adults who are physically inactive in the commuting domain (OR:3.43; 95%CI:1.09-10.82) and total PA (OR:5.58; 95%CI:1.57-19.88) present a higher risk for osteoporosis (total proximal femur or lumbar spine) compared to physically active older adults.

CONCLUSION

The risk of osteopenia is higher in older adults who are physically inactive in occupational domain and for osteoporosis the risk is higher in physically inactive in commuting domain and total habitual PA.

Evolutionary Genetic Signatures of Selection on Bone-Related Variation within Human and Chimpanzee Populations

Bone strength and the incidence and severity of skeletal disorders vary significantly among human populations, due in part to underlying genetic differentiation. While clinical models predict that this variation is largely deleterious, natural population variation unrelated to disease can go unnoticed, altering our perception of how natural selection has shaped bone morphologies over deep and recent time periods. Here, we conduct the first comparative population-based genetic analysis of the main bone structural protein gene, collagen type I α 1 (COL1A1), in clinical and 1000 Genomes Project datasets in humans, and in natural populations of chimpanzees. Contrary to predictions from clinical studies, we reveal abundant COL1A1 amino acid variation, predicted to have little association with disease in the natural population. We also find signatures of positive selection associated with intron haplotype structure, linkage disequilibrium, and population differentiation in regions of known gene expression regulation in humans and chimpanzees. These results recall how recent and deep evolutionary regimes can be linked, in that bone morphology differences that developed among vertebrates over 450 million years of evolution are the result of positive selection on subtle type I collagen functional variation segregating within populations over time.

Insufficient persistence to pharmacotherapy in Japanese patients with osteoporosis: an analysis of the National Database of Health Insurance Claims and Specific Health Checkups in Japan

In Japan, persistence and the 2-year MPR were inadequate in increasing fracture control efficacy despite a high adherence rate during the treatment period. Both factors were higher in females and those with polypharmacy but worsened with increasing age.

PURPOSE

Only a few large-scale studies have examined the care gap between the patients who need osteoporosis treatment and those who receive them in Japan. The aim of this study was to investigate the persistence and adherence to osteoporosis pharmacotherapy in Japan.

METHODS

Continuation (persistence) rates and adherence to osteoporosis pharmacotherapy were investigated using medical insurance data from the National Database of Health Insurance Claims and Specific Health Checkups of Japan, between April 2012 and March 2019.

RESULTS

The study included 528,806 male and 3,064,410 female patients. Persistence proportions were 56.6% in the first year and 46.3% in the second year. The medication possession ratio (MPR) from start to discontinuation of treatment (MPR_discon) was 94.5%, and 92.7% of patients had an MPR_discon ≥ 80%. The 2-year MPR (MPR₇₃₀) was 61.9%, and 49.6% of patients had an MPR₇₃₀ ≥ 80%. Both the persistence proportion and MPR₇₃₀ were higher in females than in males, whereas MPR_discon was higher in males. The persistence proportion and MPR₇₃₀ were highest in the 70-79 years age group, whereas MPR_discon improved with increasing age. The MPR_discon and MPR₇₃₀ were higher in the mixed-fracture and vertebral-fracture groups, respectively. The persistence proportion, MPR_discon, and MPR₇₃₀ were higher in patients with polypharmacy than in those without.

CONCLUSION

In Japan, persistence and the 2-year MPR were inadequate in increasing fracture control efficacy despite a high adherence rate during the treatment period. To bridge the care gap following osteoporosis pharmacotherapy, improvements are required for males, the elderly, and those without polypharmacy.

Relationship Between Sarcopenia, Obesity, Osteoporosis, and Cardiometabolic Health Conditions and Physical Activity Levels in Korean Older Adults

This study aimed to analyze the status of sarcopenia, obesity, osteoporosis, and cardiometabolic disease according to the level of physical activity (PA) among elderly people in Korea. Among the data obtained from the National Health and Nutrition Survey (2008–2011), we analyzed the data of a total of 3,573 Korean elderly people over 65 years of age who were surveyed for dual X-ray absorptiometry (DXA) and PA. Higher levels of PA were associated with a lower prevalence of cardiometabolic disease (χ² = 33.865, p < 0.001), osteoporosis (χ² = 94.198, p < 0.001), sarcopenia, obesity, and sarcopenic obesity (χ² = 71.828, p < 0.001). Above moderate-active PA was associated with lower body weight (p < 0.001), body fat mass (p < 0.001), and percent body fat (p < 0.001), and higher free-fat mass (p < 0.001) and appendicular skeletal muscle mass (ASM) (p < 0.001) than in low-active PA. In addition, when high-active is the risk factors of cardiometabolic were lower in waist circumference (p = 0.001), total cholesterol (TC) (p = 0.015), and triglyceride (TG) (p < 0.001) than low- and moderate-active PA, and higher in high-density lipoprotein cholesterol (HDL-C) (p < 0.001). The prevalence of cardiometabolic diseases was significantly decreased in high-active PA (odds ratio (OR) 0.60, 95% confidence interval (CI) 0.50–0.71); waist circumference (OR 0.85, 95% CI, 0.73–0.99; OR 0.59, 95% CI, 0.50–0.70) and HDL-C (OR 0.76, 95% CI, 0.65–0.88; OR 0.56, 95% CI, 0.47–0.67) significantly improved in moderate- and high-active PA, respectively, and TG (0.67 95% CI, 0.55–0.80) significantly improved in high-active PA. Osteoporosis (OR 0.62, 95% CI, 0.53–0.74; OR 0.46, 95% CI, 0.38–0.55) and sarcopenia (OR 0.77, 95% CI, 0.60–0.98; OR 0.73, 95% CI, 0.57–0.93) were significantly improved in moderate- and high-active PA, respectively. The incidence of obesity (OR 0.47, 95% CI, 0.39–0.57) and sarcopenic obesity (OR 0.47, 95% CI, 0.30–0.75) were significantly decreased in high-active PA. Therefore, we verified a lower prevalence of sarcopenia, osteoporosis, obesity, and cardiac metabolic disease in Korean elderly with more active PA. This suggests that more active PA maybe reduce the prevalence of sarcopenia, osteoporosis, obesity, and cardiometabolic diseases in older adults.

Associations between Physical Activity, Sunshine Duration and Osteoporosis According to Obesity and Other Lifestyle Factors: A Nested Case-Control Study

(1) Background: The purpose of the study was to evaluate the associations between physical activity (PA), sunshine duration (SD) and the occurrence of osteoporosis according to lifestyle status. (2) Methods: Data from the Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC) collected from 2009 to 2015 were used. Osteoporosis (n = 19,351) and control (n = 38,702) participants were matched in a 1:2 ratio according to age, sex, income, and region of residence. PA was classified as moderate- to high-intensity PA (MHPA) or low-intensity PA (LPA) based on the International Physical Activity Questionnaire (IPAQ). SD was classified as short (≤6 h) or long (>6 h). Conditional logistic regression was used to calculate the odds ratios (ORs) with 95% confidence intervals (CIs) of MHPA and long SD for the occurrence of osteoporosis. Subgroup analyses were performed according to SD (or PA), obesity, smoking, and alcohol consumption. (3) The adjusted OR of MHPA for osteoporosis was 0.90 (95% CI = 0.87-0.94). The results were consistent in the age/sex, SD, obesity, smoking, and alcohol consumption subgroups, but not the <60-year-old male and underweight subgroups. The adjusted OR of long SD for osteoporosis was 0.96 (95% CI = 0.93-1.00). The findings were consistent in the <60-year-old female, obese, nonsmoker, and <1 time a week alcohol consumption subgroups. (4) Conclusions: We suggest that both higher intensity of PA and long SD could decrease the risk of osteoporosis. Specifically, PA could decrease the risk of osteoporosis in individuals with most characteristics except male sex or underweight. Long SD could decrease the risk of osteoporosis in young females, obese individuals, nonsmokers, and individuals with lower alcohol consumption.

Osteoporosis in Men: A Review of an Underestimated Bone Condition

Osteoporosis is called the 'silent disease' because, although it does not give significant symptoms when it is not complicated, can cause fragility fractures, with serious consequences and death. Furthermore, the consequences of osteoporosis have been calculated to weigh heavily on the costs of health systems in all the countries. Osteoporosis is considered a female disease. Actually, the hormonal changes that occur after menopause certainly determine a significant increase in osteoporosis and the risk of fractures in women. However, while there is no doubt that women are more exposed to osteoporosis and fragility fractures, the literature clearly indicates that physicians tend to underestimate the osteoporosis in men. The review of the literature done by the authors shows that osteoporosis and fragility fractures have a high incidence also in men; and, furthermore, the risk of fatal complications in hip fractured men is higher than that for women. The authors report the evidence of the literature on male osteoporosis, dwelling on epidemiology, causes of osteoporosis in men, diagnosis, and treatment. The analysis of the literature shows that male osteoporosis is underscreened, underdiagnosed, and undertreated, both in primary and secondary prevention of fragility fractures.
