Dual-energy X-ray absorptiometry (DXA) and bone turnover markers (BTMs) track changes in bone mineral density (BMD) and turnover. Calcium (Ca) Isotope Markers (CIM), which measure naturally occurring variations in stable Ca isotope ratios in serum (CIM_serum) and urine (CIM_urine), offer a potentially more sensitive and individualized approach for monitoring bone health and therapy responsiveness. In this pilot study, 13 postmenopausal women with DXA-confirmed osteoporosis were initiated on denosumab. Over 24 weeks, serial measurements of CIM_serum, CIM_urine, BMD, BTMs, and parathyroid hormone (PTH) were obtained. CIM thresholds distinguishing net bone Ca uptake from net bone Ca efflux were applied. Baseline CIM values, adjusted for Ca supplement intake (average CIM_serum: -1.09 ± 0.15 ‰ and CIM_urine: 0.00 ± 0.22 ‰), indicated net bone Ca loss. After 60 mg denosumab injection, all patients showed substantial increases in CIM_serum and CIM_urine values by ~ + 0.4 ‰ after one week. Peak values were reached in week 4 (CIM_serum: ~ - 0.8 ‰) to 8 (CIM_serum: ~ - 0.7 ‰). CIM_serum and CIM_urine values correlated positively to PTH. Some patients´ CIM values quickly rose above threshold levels, while others showed more modest or transient changes. Although DXA indicated an increase in the lumbar and hip T-score values after 24 weeks, DXA primarily confirmed group-level gains. BTMs did not reflect individual variations in CIM response. While further validation in larger, controlled cohorts is warranted, these findings highlight CIM's potential to enhance osteoporosis management through personalized treatment monitoring.</p>","PeriodicalId":93913,"journal":{"name":"Bone","volume":" ","pages":"117522"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144082757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MGL3196 (MGL) is a therapeutic thyroid hormone receptor beta (TRβ) agonist that has been shown to rescue non-alcoholic steatohepatitis by enhancing lipid metabolism. In a previous study, we demonstrated that MGL treatment protected against high-fat diet (HFD)-induced adiposity but increased HFD-induced trabecular bone loss in male mice. In this study, we explored the impact of MGL treatment on adiposity, bone, and cartilage in aged-21-month-old C57BL/6 J mice after a 12-week HFD regimen. Our results show that MGL reduced body weight as well as adverse effects caused by HFD adiposity, in male mice only. Aged HFD-fed male mice experienced cortical bone loss, in contrast to the trabecular bone loss observed in adult male mice. Notably, MGL treatment further exacerbated the cortical bone loss. Mechanical testing of tibias from aged male mice by 3-point bending revealed a reduced maximum load and tibia stiffness with HFD and MGL treatment. Transcriptome analyses for cortical bone formation regulators unveiled a decreased expression of Wnt16 and increased expression of the Wnt inhibitor, Sost, in the bones of HFD-fed male mice. Additionally, measurements of articular cartilage indicated that MGL treatment reduced articular cartilage degradation in both sexes, which was attributed to aging and a HFD. Our findings suggest tailored therapies are necessary to address the adverse effects of a HFD on fat, bone, and cartilage metabolism, specifically considering factors such as age and sex.</p>","PeriodicalId":93913,"journal":{"name":"Bone","volume":" ","pages":"117516"},"PeriodicalIF":0.0,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144060329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Glyconutrients and synbiotics are promising options for improving immune function. Therefore, we hypothesized that combining synbiotics and glyconutrients will enhance pig nutrient utilization. 150 pigs (Landrace × Yorkshire × Duroc), initially weighing 58.85 ± 3.30 kg of live body weight (BW) were utilized to determine the effects of synbiotics-glyconutrients (SGN) on the pigs' performance, feed efficiency, gas emission, pork traits, and composition of fatty acids. The pigs were matched by BW and sex and chosen at random to 1 of 3 diet treatments: control = Basal diet; TRT1 = Basal diet + SGN 0.15%; TRT2 = Basal diet + SGN 0.30%%. The trials were conducted in two phases (weeks 1-5 and weeks 5-10). The average daily gain was increased in pigs fed a basal diet with SGN (<i>p</i> = 0.036) in weeks 5-10. However, the apparent total tract digestibility of dry matter, nitrogen, and gross energy did not differ among the treatments (<i>p</i> > 0.05). Dietary treatments had no effect on NH₃, H₂S, methyl mercaptans, acetic acids, and CO₂ emissions (<i>p</i> > 0.05). Improvement in drip loss on day 7 (<i>p</i> = 0.053) and tendency in the cooking loss were observed (<i>p</i> = 0.070) in a group fed basal diets and SGN at 0.30% inclusion level. The group supplemented with 0.30% of SGN had higher levels of palmitoleic acid (C16:1), margaric acid (C17:0), omega-3 fatty acid, omega-6 fatty acid, and ω-6: ω-3 ratio (<i>p</i> = 0.034, 0.020, 0.025, 0.007, and 0.003, respectively) in the fat of finishing pigs. Furthermore, group supplemented with 0.30% of SGN improved margaric acid (C17:0), linoleic acid (C18:2n6c), arachidic acid (C20:0), omega 6 fatty acid, omega-6 to omega-3 ratio, unsaturated fatty acid, and monounsaturated fatty acid (p = 0.037, 0.05, 0.0142, 0.036, 0.033, 0.020, and 0.045, respectively) in the lean tissues of finishing pigs compared to pigs fed with the control diets. In conclusion, the combination of probiotics, prebiotics, and glyconutrients led to higher average daily gain, improved the quality of pork, and more favorable fatty acid composition.

Yet, the increase in fracture risk in type 1 diabetes (T1D) patients is not fully captured by bone mineral density (BMD), leading to the hypothesis that alterations in bone quality are responsible for the increased risk. Material/compositional properties are important aspects of bone quality, yet information on human bone material/compositional properties in T1D is rather sparse. The purpose of the present study is to measure both the intrinsic material behaviour by nanoindentation, and material compositional properties by Raman spectroscopy as a function of tissue age and microanatomical location (cement lines) in bone tissue from iliac crest biopsies from postmenopausal women diagnosed with long-term T1D (N = 8), and appropriate sex-, age-, BMD- and clinically-matched controls (postmenopausal women; N = 5). The results suggest elevation of advanced glycation endproducts (AGE) content in the T1D and show significant differences in mineral maturity / crystallinity (MMC) and glycosaminoglycan (GAG) content between the T1D and control groups. Furthermore, both hardness and modulus by nanoindentation are greater in T1D. These data suggest a significant deterioration of material strength properties (toughness) and compositional properties in T1D compared with controls.","PeriodicalId":93913,"journal":{"name":"Bone","volume":"1 1","pages":"116832"},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45367411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are not constant and differ from those of adults due to the growth processes taking place. Accordingly, reference levels of AP continuous across these ages were generated for boys and girls based on of a large German health- and population-based study, LIFE Child. We considered AP at different growth and Tanner stages and additionally its association with other anthropometric parameters. The association between AP and BMI was of particulary great interest due to controversial literature on this topic. The role of AP in liver metabolism was investigated by examining ALAT, ASAT, and GGT.\u0000\u0000\u0000METHODS\u00003976 healthy children (12,093 visits) were included from the LIFE Child study from 2011 to 2020. The subjects´ age ranged from 3 months to 18 years. Serum samples from 3704 subjects (10,272 cases, 1952 boys and 1753 girls) were analysed for AP after applying specific exclusion criteria. After calculating of reference percentiles, associations between AP and height-SDS, growth velocity, BMI-SDS, Tanner stage and the liver enzymes ALAT, ASAT and GGT were examined via linear regression models.\u0000\u0000\u0000RESULTS\u0000In the continuous reference levels, AP showed a first peak during the first year of life, followed by a plateau at a lower level until the start of puberty. In girls, AP increased beginning at the age 8, with a peak around 11 years, in boys beginning at the age 9, with a peak around age 13. Afterwards, AP values decreased continuously until age 18. In Tanner stages 1 and 2, AP levels did not differ between the two sexes. We found a strong positive association between AP-SDS and BMI-SDS. We also observed a significantly positive association between AP-SDS and height-SDS, which was stronger in boys than in girls. We found different intensities in the associations of AP with growth velocity depending on age group and sex. Furthermore, we found a significantly positive association between ALAT and AP in girls but not in boys, whereas ASAT-SDS and GGT-SDS were significantly positively associated with AP-SDS in both sexes.\u0000\u0000\u0000CONCLUSION\u0000Sex and age, but also BMI may act as confounding factors for AP reference ranges. Our data confirm the remarkable association between AP and growth velocity (or height-SDS, respectively) during infancy and puberty. In addition, we were able to specify the associations between AP and ALAT, ASAT, and GGT and their differences in both sexes. These relations should be considered when evaluating liver and bone metabolism markers, especially in infancy.","PeriodicalId":93913,"journal":{"name":"Bone","volume":"1 1","pages":"116809"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41642183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
