A study of associations between early DHA status and fatty acid desaturase (FADS) SNP and developmental outcomes in children of obese mothers
AbstractDHA from diet or endogenous synthesis has been proposed to affect infant development, however, results are inconclusive. In this study, we aim to verify previously observed fatty acid desaturase gene cluster (FADS) SNP-specific associations with erythrocyte DHA status in 9-month-old children and sex-specific association with developmental outcomes. The study was performed in 166 children (55 % boys) of obese mothers. Erythrocyte fatty acid composition was analysed in blood-samples obtained at 9 months of age, and developmental outcomes assessed by the Ages and Stages Questionnaire at 3 years. Erythrocyte DHA level ranged from 4·4 to 9·9 % of fatty acids, but did not show any association withFADSSNP or other potential determinants. Regression analysis showed associations between erythrocyte DHA and scores for personal–social skills (β1·8 (95 % CI 0·3, 3·3),P=0·019) and problem solving (β3·4 (95 % CI 1·2, 5·6),P=0·003). A tendency was observed for an association in opposite direction between minor alleles (G-variant) of rs1535 and rs174575 and personal–social skills (P=0·062 and 0·068, respectively), which became significant when the SNP were combined based on their previously observed effect on erythrocyte DHA at 9 months of age (β2·6 (95 % CI 0·01, 5·1),P=0·011). Sex–SNP interaction was indicated for rs174575 genotype on fine motor scores (P=0·016), due to higher scores among minor allele carrying girls (P=0·043), whereas no effect was seen among boys. In conclusion, DHA-increasingFADSSNP and erythrocyte DHA status were consistently associated with improved personal–social skills in this small cohort of children of obese mothers irrespective of sex, but the sample was too small to verify potential sex-specific effects.</jats:p
Bone Density and Structure in Overweight Men With and Without Diabetes
OBJECTIVE: Metabolic syndrome (MetS), type 1 diabetes (T1D), and type 2 diabetes, are associated with an increased risk of fractures; however, the impact of obesity on bone deficits in diabetes is unknown. We aimed to compare markers of bone structure, bone density, and bone turnover in non-diabetic overweight men with MetS and overweight men with T1D or T2D. METHODS AND RESEARCH DESIGN: In this cross-sectional study we included participants from two previously described study cohorts consisting of participants with diabetes and participants with MetS. Participants underwent dual-energy X-ray absorptiometry measuring areal bone mineral density (aBMD) at the hip and lumbar spine, High Resolution peripheral Quantitative (HRpQCT) scan of the tibia and radius and measurement of circulating bone turnover markers. We compared groups with unpaired t test and performed multiple linear regression with adjustment for age, body mass index, and smoking. RESULTS: We included 33 participants with T1D, 25 participants with T2D, and 34 participants with MetS. Bone turnover markers levels were comparable between T1D and MetS. aBMD at the hip was lower in T1D compared to MetS, also after adjustment. P1NP and Osteocalcin levels were lower among individuals with T2D compared to MetS, whereas aBMD were similar between the groups after multiple adjustments. We observed no difference in volumetric BMD at the tibia or radius between MetS and T1D and T2D, respectively. Participants with T2D had a higher trabecular number and lower trabecular separation compared to individuals with MetS at the tibia, which remained signficant after multiple adjustments. CONCLUSION: In conclusion, we observed no clinically important differences in bone density or structure between men with T2D, T1D, or MetS. However, men with T2D displayed lower bone turnover compared to MetS highlighting that T2D per se and not obesity, is associated with low bone turnover

Association of Potent and Very Potent Topical Corticosteroids and the Risk of Osteoporosis and Major Osteoporotic Fractures
IMPORTANCE: Systemic and inhaled corticosteroids negatively affect bone remodeling and cause osteoporosis and bone fracture when given continuously or in high doses. However, risk of osteoporosis and major osteoporotic fracture (MOF) after application of topical corticosteroids (TCSs) is largely unexplored. OBJECTIVE: To examine the association between cumulative exposure to potent and very potent TCSs and risk of osteoporosis and MOF. DESIGN, SETTING, AND PARTICIPANTS: This nationwide retrospective cohort study included 723 251 Danish adults treated with potent or very potent TCSs from January 1, 2003, to December 31, 2017. Data were obtained from Danish nationwide registries. Filled prescription data were converted in equipotent doses to mometasone furoate (1 mg/g). Data were analyzed from June 1 to August 31, 2019. EXPOSURES: Patients were considered exposed when they had filled prescriptions of cumulative amounts corresponding to the equivalent of at least 500 g of mometasone, using filled prescriptions of 200 to 499 g as the reference group. MAIN OUTCOMES AND MEASURES: The co-primary outcomes were a diagnosis of osteoporosis or MOF. Hazard ratios (HRs) adjusted for age, sex, socioeconomic status, medication use, and comorbidity were calculated with 95% CIs using Cox proportional hazards regression models. RESULTS: A total of 723 251 adults treated with the equivalent of at least 200 g of mometasone were included in the analysis (52.8% women; mean [SD] age, 52.8 [19.2] years). Dose-response associations were found between increased use of potent or very potent TCSs and the risk of osteoporosis and MOF. For example, HRs of MOF were 1.01 (95% CI, 0.99-1.03) for exposure to 500 to 999 g, 1.05 (95% CI, 1.02-1.08) for exposure to 1000 to 1999 g, 1.10 (95% CI, 1.07-1.13) for exposure to 2000 to 9999 g, and 1.27 (95% CI, 1.19-1.35) for exposure to at least 10 000 g. A 3% relative risk increase of osteoporosis and MOF was observed per doubling of the cumulative TCS dose (HR, 1.03 [95% CI, 1.02-1.04] for both). The overall population-attributable risk was 4.3% (95% CI, 2.7%-5.8%) for osteoporosis and 2.7% (95% CI, 1.7%-3.8%) for MOF. The lowest exposure needed for 1 additional patient to be harmed (454 person-years) was observed for MOF with exposure of at least 10 000 g. CONCLUSIONS AND RELEVANCE: These findings demonstrate that use of high cumulative amounts of potent or very potent TCSs was associated with an increased risk of osteoporosis and MOF
The dental perspective on osteogenesis imperfecta in a Danish adult population
Abstract Background To report on dental characteristics and treatment load in Danish adult patients with osteogenesis imperfecta (OI). Methods Oral examination of 73 patients with OI was performed and OI type I, III, and IV were represented by 75.3%, 8.2%, and 16.4%, respectively. Patients were diagnosed as having dentinogenesis imperfecta (DI) if they had clinical and radiological signs of DI. In the data analysis, mild OI (type I) was compared to moderate-severe OI (type III and IV). Results Discoloration of teeth was prevalent in patients with moderate-severe compared to mild OI (83.3% vs. 5.5%, p < 0.001). Cervical constriction and pulpal obliteration were frequent findings in patients with moderate-severe OI (61.1% and 88.9%, respectively), whereas pulp stones and taurodontism were diagnosed in patients with mild OI only (29.1% and 9.1%, respectively). DI was found in 24.7% of OI patients and considerably more frequent in patients with moderate-severe (94.4%) compared to mild OI (1.8%) (p < 0.001). The number of teeth with artificial crowns was significantly higher in patients with moderate-severe OI than in patients with mild OI (median 1.5, range 0–23 vs. median 0, range 0–14) (p < 0.001). The number of teeth with fillings in patients with mild OI was significantly higher than in patients with moderate-severe OI (mean 9.7, SD 5.1, median 9.0, range 1–21 vs. mean 5.0, SD 4.4, median 4.0, range 0–16) (p < 0.001). Conclusions One fourth of patients with OI had DI, and the vast majority of them had moderate-severe OI. Whereas discoloration of teeth, cervical constriction and pulp obliteration were frequent findings in patients with moderate-severe OI, pulp stones and taurodontism were found in patients with mild OI only. In patients with moderate-severe OI, the dental treatment load was dominated by prosthetic treatment, whereas restorative treatment with fillings was more prevalent in patients with mild OI
