Abstract
PURPOSE To investigate whether patients with severe motor and intellectual disability (SMID) have nutritional vitamin D and K insufficiencies and clarify the required vitamin supplementation. METHODS This prospective observational study enrolled Japanese adults with SMID receiving institutionalized care who underwent blood sampling between February 2020 and February 2022 during annual medical checkups. Serum vitamin K1 and 25-hydroxy vitamin D (25(OH)D) levels were measured to determine their relationship with serum uncarboxylated osteocalcin (ucOC) levels. Vitamin D and K intake was compared among tube-fed and oral-intake patients with SMID and control participants using corresponding serum levels. RESULTS The study included 124 patients with SMID (56 men and 68 women; mean age: 53.0 years) and 20 control participants. Serum 25(OH)D levels were significantly higher in the SMID group than in the control group and the oral intake SMID group than in the tube-fed SMID group. In the tube-fed SMID group, vitamin D intake was lower than the daily recommended intake and correlated with serum 25(OH)D levels. Daily vitamin K intake in the tube-fed group was lower than recommended but not correlated with serum vitamin K levels. Serum ucOC levels were significantly higher in the SMID group than in the control group. Tube feeding was significantly and positively correlated with serum 25(OH)D levels. Serum 25(OH)D levels were not correlated with serum vitamin K1 levels. CONCLUSIONS The SMID group had higher ucOC levels than the control group, possibly owing to daily vitamin K and D deficiencies. Vitamin D supplementation is recommended to decrease ucOC levels.

Abstract
AIM Vitamin D (VD) affects skeletal muscles. The high prevalence of VD deficiency in Japan may lead to decreased skeletal muscle mass and strength, increasing the prevalence of sarcopenia. Therefore, we aimed to investigate the association between serum VD levels and skeletal muscle indices in a Japanese community-dwelling older population. METHODS We extracted data from the Septuagenarians, Octogenarians, Nonagenarians Investigation with Centenarians (SONIC) study. We analyzed the data for participants in the 70s and 90s age groups. Skeletal mass index (SMI) using bioimpedance analysis, grip strength, walking speed, and serum VD levels using 25-hydroxyvitamin D [25(OH)D] were measured. RESULTS We analyzed the data of 310 participants in their 70s and 48 in their 90s. Mean serum 25(OH)D levels were 21.6 ± 5.0 ng/mL in the 70s group and 23.4 ± 9.1 ng/mL in the 90s group. In the 70s group, serum 25(OH)D levels correlated with SMI (r = 0.21, P < 0.0001) and grip strength (r = 0.30, P < 0.0001). Serum 25(OH)D levels were independently associated with SMI after adjusting for sex, body mass index, and serum albumin levels. In the 90s group, serum 25(OH)D levels were correlated with SMI (r = 0.29, P = 0.049) and grip strength (r = 0.34, P = 0.018). However, the multivariate analysis showed no independent association between SMI, grip strength, and serum 25(OH)D levels. CONCLUSION In a cross-sectional analysis of an older population, serum VD levels were associated with SMI and grip strength, and this association was more pronounced in the 70s group than in the 90s group. Our results suggest that serum VD levels maintain skeletal muscle mass and grip strength. Geriatr Gerontol Int 2024; ••: ••-••.

Association between Serum 25-Hydroxyvitamin D Levels and Sarcopenia in Patients Undergoing Chronic Haemodialysis. Am J Nephrol 2024; 55:399-405. [PMID: 38310857 DOI: 10.1159/000536582] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Accepted: 01/31/2024] [Indexed: 02/06/2024]
Abstract
INTRODUCTION Sarcopenia and vitamin D deficiency are highly prevalent among patients undergoing haemodialysis. Although vitamin D deficiency, assessed using serum 25-hydroxyvitamin D (25(OH)D) levels, is known to be associated with sarcopenia in the general population, whether serum 25(OH)D levels are associated with sarcopenia in patients undergoing haemodialysis with suppressed renal activation of 25(OH)D remains unclear. This study aimed to examine the association between serum 25(OH)D levels and sarcopenia in patients undergoing haemodialysis. METHODS Serum 25(OH)D level measurements and assessment of sarcopenia using the Asian Working Group for Sarcopenia criteria were conducted in 95 stable outpatients undergoing maintenance haemodialysis therapy. RESULTS Sarcopenia was observed in 22 (23.1%) patients. In multiple logistic regression analysis, serum 25(OH)D levels were associated with sarcopenia (odds ratio [OR] 0.87, 95% confidence interval [CI] 0.77-0.99, p = 0.039) independent of traditional risk factors for sarcopenia. In multiple linear regression analyses, serum 25(OH)D levels were associated with parameters of skeletal muscle mass and strength (β = 0.145, p = 0.046, and β = 0.194, p = 0.020, respectively). The adjusted OR for sarcopenia was 5.60 (95% CI 1.52-20.57, p = 0.009) in the vitamin D deficiency group categorized based on the cut-off serum 25(OH)D level of 10 ng/mL. Regarding model discrimination, adding vitamin D deficiency to the traditional risk factors significantly improved the integrated discrimination improvement score (0.093, p = 0.007). CONCLUSION Lower serum 25(OH)D levels were associated with sarcopenia independent of traditional risk factors in patients undergoing haemodialysis with suppressed vitamin D activation in the kidney. This finding implies that circulating 25(OH)D may have an important relationship with the skeletal muscle function of patients undergoing haemodialysis, and its measurement may be recommended to identify patients at high risk for sarcopenia among those undergoing haemodialysis.

Abstract
BACKGROUND Vitamin D insufficiency/deficiency is related to fragility fracture. In most previous studies, there was no assessment of vitamin D deficiency status separately for hip fracture types. The first aim is to evaluate vitamin D and parathyroid hormone (PTH) status in patients with hip fracture. The second objective is to determine whether there are differences in vitamin D and PTH between the femoral neck fracture and the femoral metaphyseal fracture group. METHODS 62 men and 248 women with fragility hip fractures were enrolled. 25-hydroxyviamin D [25(OH)D] and intact PTH (iPTH) values were evaluated, and femoral neck bone mineral density (BMD) was measured on the uninjured side. Vertebral fractures (VFs) were assessed using radiographs of the thoracic and lumbar spine. We examined the relationships of 25(OH)D value with the number of prevalent VFs, T-score of femoral neck, and iPTH level. These analyses were also performed, neck fracture and trochanteric fracture separately. RESULTS Mean age was 85 years. The mean 25(OH)D was 11.2 (range, 4.0-26.1) ng/ml, whereas the mean iPTH value was 48.9 pg/ml (range, 9-429 pg/ml). The mean number of VFs was 1.5 (range, 0-11), and the mean T-score was -3.3 (range, -5.2 to -0.5). There was a weak correlation between the 25(OH)D value and the number of VFs. There was a weak but significant correlation between 25(OH)D and iPTH values. In the patients with trochanteric fractures, 25(OH)D value was significantly lower and iPTH value was significantly higher than those with neck fractures. There was a significant correlation between the 25(OH)D value and number of the VFs, 25(OH)D, and iPTH values only in trochanteric fractures. CONCLUSIONS Vitamin D deficiency was severe and PTH levels were higher in the trochanteric fractures. Both vitamin D deficiency and high PTH levels were suggested to have association with bone fragility.

Abstract
Several studies have reported that vitamin D may modify human reproductive functions; however, the results are conflicting. We aimed to comprehensively evaluate serum vitamin D levels and examine the relationship between serum vitamin D levels and ovarian reserve markers, and immune markers of implantation, in reproductive-aged Japanese women with infertility.in reproductive-aged women with infertility. This cross-sectional, single-center study included reproductive-aged women who underwent preconception screening for fertility. Serum vitamin D levels and reproductive and immune markers were measured. Standard and advanced statistical techniques were used. We observed a statistically significant difference in the seasonal and monthly 25(OH) vitamin D levels; the 25(OH) vitamin D level during winter was the lowest among all seasons. However, there was no linear correlation between 25(OH) vitamin D levels and ovarian reserve markers, such as follicle-stimulating hormone and anti-Müllerian hormone, or the Th1/Th2 cell ratio, which is used as an implantation-related immunological marker. In this large-scale study, we evaluated the serum 25(OH) vitamin D concentration in reproductive-aged women with infertility in Japan; however, there was no association between reproductive function and vitamin D levels.

Vitamin D status-associated postoperative complications in patients with hip dysplasia after periacetabular osteotomy: A case-control study. Mod Rheumatol 2023; 33:1176-1182. [PMID: 36197741 DOI: 10.1093/mr/roac120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Revised: 08/01/2022] [Accepted: 09/23/2022] [Indexed: 11/13/2022]
Abstract
OBJECTIVES This study aimed to clarify the relationship between vitamin D status and complications after periacetabular osteotomy. METHODS A total of 46 hips of 39 patients (3 men and 36 women; mean age at surgery, 41.0 years; mean postoperative follow-up duration, 63 months) were reviewed to obtain the following information: patients' serum 25-hydroxyvitamin D [25(OH)D] status, prevalence of postoperative delayed union of osteotomy sites in the greater trochanter (DUGT) and ischiopubic stress fractures (IPSFs), and risk factors. RESULTS The mean serum 25(OH)D level was 11.9 ng/ml. DUGT and IPSF were found in four (10.3%) and three (7.7%) patients, respectively. Serum 25(OH)D levels ≤ 11 ng/ml were significantly associated with DUGT in female patients (p = .02). Serum 25(OH)D levels ≤ 9 ng/ml and smoking were significantly associated with IPSF (p = 0.01 and 0.02, respectively). Overall, 21.7% of patients with serum 25(OH)D levels ≤ 11 ng/ml developed at least one complication; no complications occurred when serum 25(OH)D levels were >11 ng/ml. CONCLUSION Severe vitamin D deficiency was highly prevalent in relatively young patients. Vitamin D deficiency and smoking were independent risk factors for postoperative complications. Proactive supplementation is advisable to reduce postoperative complications, especially in patients with serum 25(OH)D levels ≤ 11 ng/ml.

Analysis of vitamin D metabolites in biological samples using a nanoluc-based vitamin D receptor ligand sensing system: NLucVDR. J Steroid Biochem Mol Biol 2023; 233:106367. [PMID: 37517743 DOI: 10.1016/j.jsbmb.2023.106367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Revised: 06/28/2023] [Accepted: 07/22/2023] [Indexed: 08/01/2023]
Abstract
Many assays are currently being developed to measure the levels of vitamin D metabolites in various samples (such as blood, urine, and saliva). This study focused on the measurement of vitamin D metabolites in serum and urine using the NLucVDR assay system, which consists of a split-type nanoluciferase and ligand-binding domain (LBD) of the human vitamin D receptor. Blood and urine samples were collected from 23 participants to validate the NLucVDR assay. The 25(OH)D3 levels in the serum and urine determined by the NLucVDR assay showed good correlations with those determined by standard analytical methods (ECLIA for serum and LC-MS/MS for urine), with correlation coefficients of 0.923 and 0.844 for serum and urine samples, respectively. In the case of serum samples, 25(OH)D3 levels determined by the NLucVDR assay were in good agreement with those determined by ECLIA. Therefore, the NLucVDR assay is a useful tool for measuring serum 25(OH)D3 levels. The contribution of each vitamin D metabolite to the luminescence intensity obtained during the NLucVDR assay depends on its concentration and affinity for NLucVDR. Thus, the contribution of 25(OH)D3 in serum appears to be much higher than that of the other metabolites. In contrast, the 25(OH)D3 levels in the urine determined by the NLucVDR assay were more than 20-fold higher than those determined by a standard analytical method (LC-MS/MS), suggesting that some vitamin D metabolite(s) in the urine remarkably increased the luminescence intensity of the NLucVDR assay. Notably, the 25(OH)D3 concentration in the urine determined by the NLucVDR assay and the serum 25(OH)D3 concentration determined by standard analytical methods showed a significant positive correlation (r = 0.568). These results suggest that the analysis of a small amount of urine using the NLucVDR assay may be useful for predicting the serum 25(OH)D3 levels.

Abstract
AIM To evaluate the association between vitamin D status and periodontal inflammation as determined by the periodontal inflamed surface area (PISA) in community-dwelling older adults. MATERIALS AND METHODS This cross-sectional study included 467 Japanese adults (mean age = 73.1 years) who underwent full-mouth periodontal examinations and measurements of serum levels of 25-hydroxyvitamin D (25(OH)D). We used linear regression and restricted cubic spline models to analyse the association between exposure (serum 25(OH)D) and outcome (PISA). RESULTS The linear regression model showed that, after adjusting for potential confounders, participants in the lowest quartile of serum 25(OH)D had 41.0 mm2 more PISA (95% confidence interval [CI]: 4.6-77.5) than the reference group (the highest quartile of serum 25(OH)D). The spline model showed that the association between serum 25(OH)D and PISA was non-linear and restricted to the low 25(OH)D range. PISA initially sharply decreased as serum 25(OH)D increased, and then the decreasing trend slowed and plateaued. The inflection point with the minimum PISA value was a serum 25(OH)D level of 27.1 ng/mL, above which there was no decreasing trend in PISA with increasing serum 25(OH)D levels. CONCLUSIONS Low vitamin D status had an L-shaped association with periodontal inflammation in this cohort of Japanese adults.

Oku Y, Noda S, Yamada A, Nakaoka K, Goseki-Sone M. Vitamin D restriction and/or a high-fat diet influence intestinal alkaline phosphatase activity and serum endotoxin concentration, increasing the risk of metabolic endotoxemia in rats. Nutr Res 2023; 112:20-29. [PMID: 36934524 DOI: 10.1016/j.nutres.2023.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 02/16/2023] [Accepted: 02/17/2023] [Indexed: 02/24/2023]
Abstract
Vitamin D insufficiency induces calcification disorder of bone or a decrease in bone mineral density, increasing the risk of fracture. Alkaline phosphatase (ALP) activity, a differentiation marker for intestinal epithelial cells, is regulated by vitamin D. It has also been suggested that ALP may prevent metabolic endotoxemia by dephosphorylating lipopolysaccharide. We hypothesized that vitamin D restriction and/or a high-fat diet influences ALP activity in each tissue and serum lipopolysaccharide concentrations and increases the risk of metabolic endotoxemia. Eleven-week-old female rats were divided into 4 groups: basic control diet (Cont.), basic control diet with vitamin D restriction (DR), high-fat diet (HF), and high-fat diet with vitamin D restriction (DRHF) groups. They were acclimated for 28 days. The results of 2-way analysis of variance showed that intestinal ALP activity, which may contribute to an improvement in phosphate/lipid metabolism and longevity, in the high-fat diet groups (HF and DRHF) was higher than in the low-fat diet groups (Cont. and DR). ALP activity in the vitamin D-restricted groups (DR and DRHF) was lower than in the vitamin D-sufficient groups (Cont. and HF). Furthermore, serum endotoxin concentrations were significantly higher in the high-fat diet groups (HF and DRHF) than in the low-fat diet groups (Cont. and DR). In the vitamin D-restricted groups (DR and DRHF), serum endotoxin concentrations were also significantly higher than in the vitamin D-sufficient groups (Cont. and HF). These results suggest that vitamin D restriction and/or a high-fat diet increases the risk of metabolic endotoxemia.

Incidence Trend of Follicular Lymphoma in Taiwan Compared to Japan and Korea, 2001-2019. J Clin Med 2023; 12:jcm12041417. [PMID: 36835952 PMCID: PMC9963002 DOI: 10.3390/jcm12041417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2023] [Revised: 02/01/2023] [Accepted: 02/09/2023] [Indexed: 02/12/2023] Open
Abstract
A continuous increase in follicular lymphoma has been observed in Taiwan, Japan, and South Korea over the last few decades. This study aimed to evaluate the difference in incidence trends of follicular lymphoma in Taiwan, Japan, and South Korea between 2001 and 2019. The data for the Taiwanese populations was obtained from the Taiwan Cancer Registry Database, and those for the Japanese and Korean population were retrieved from the Japan National Cancer Registry and some additional reports, both of which included population-based cancer registry data, from Japan and Korea. Follicular lymphoma accounted for 4231 cases from 2002-2019 in Taiwan, 3744 cases from 2001-2008 and 49,731 cases from 2014-2019 in Japan; and 1365 cases from 2001-2012 and 1244 cases from 2011-2016 in South Korea. The annual percentage change for each time period was 3.49% (95% confidence interval: 2.75-4.24%) in Taiwan, 12.66% (95% confidence interval [CI]: 9.59-15.81%) and 4.95% (95% CI: 2.14-7.84%) in Japan, and 5.72% (95% CI: 2.79-8.73%) and 7.93% (95% CI: -1.63-18.42%) in South Korea. Our study confirms that the increasing trends of follicular lymphoma incidence in Taiwan and Japan have been remarkable in recent years, especially the rapid increase in Japan between 2014 and 2019; however, there was no significant in-crease from 2011 to 2015 in South Korea.

Abstract
INTRODUCTION Locomotive syndrome (LOCOMO) is defined by the Japanese Orthopaedic Association (JOA) as a condition requiring nursing care due to a decline in mobility resulting from musculoskeletal disorders. In 2020, the JOA announced the new definition of LOCOMO stage 3 and revision of clinical decision limits in stages of LOCOMO. However, there are few reports on the epidemiological indices of LOCOMO. This prospective cohort study aimed to investigate the prevalence, incidence, and association of poor prognosis with LOCOMO stages. MATERIALS AND METHODS The third survey of the Research on Osteoarthritis/Osteoporosis Against Disability (ROAD) study was conducted during 2012-2013, examining a population-based cohort of 1575 participants (513 men and 1062 women, mean age 65.6 years). Three LOCOMO risk tests were performed, and patients were classified into LOCOMO stages 0, 1, 2, and 3. They were followed up for 6 years, and identical examination of LOCOMO was performed in 3- and 6-year follow-ups. Data on patients' prognoses, including disability and death, were collected. RESULTS The prevalence of LOCOMO stages 1, 2, and 3 was 41.3, 14.9, and 11.6%, respectively. The incidence of LOCOMO stages 1, 2, and 3 were 83.7, 23.0, and 18.6 per 1000 person-years, respectively. Compared with LOCOMO stage 0, logistic regression analysis showed that LOCOMO stage 3 significantly increased the risk of disability and mortality. In addition, each value of LOCOMO risk tests for LOCOMO stage 3 increased the risk of poor prognosis. CONCLUSION LOCOMO stage 3 is a sensitive indicator of future disability and mortality.

Abstract
Resumo O objetivo deste artigo é analisar a insuficiência de vitamina D e fatores associados em idosos assistidos na atenção primária à saúde. Trata-se de um estudo transversal que avaliou 533 idosos (≥ 60 anos) em três cidades do estado de São Paulo, Brasil. Foi avaliada a 25-hidroxivitamina D (25 OH D) sérica por quimioluminescência. Os fatores avaliados foram condições sociodemográficas (sexo, faixa etária, etnia, escolaridade, renda, estado civil), de saúde (doenças referidas), composição corporal (IMC, circunferência da cintura), estilo de vida (atividade física e tabagismo) e exposição solar (finalidade, duração, frequência e horário de exposição, partes expostas, uso de protetor solar, tipo de pele). A prevalência de insuficiência foi de 64,5%, com associação para sexo feminino, etnia não brancos/não declarados, baixo peso, circunferência da cintura elevada (risco para DCV) e inatividade física. Houve associação negativa para exposição solar habitual de mãos, braços e pernas, durante atividade de lazer, deslocamentos diários e atividade física e entre as 9h e 15h. Os achados mostram a relevância de fatores como sexo, etnia, composição corporal, atividade física e hábitos de exposição solar na alta prevalência de níveis inadequados de vitamina D em idosos.

Abstract
OBJECTIVE The primary purpose of this cross-sectional study was to investigate the characteristics of age-related changes in bone microstructure on high-resolution peripheral quantitative computed tomography (HR-pQCT), areal bone mineral density (aBMD) on dual-energy X-ray absorptiometry (DXA), and bone-related biochemical markers in men. The secondary purpose of this study was to examine how bone microstructure is related to aBMD and biochemical markers. METHODS The subjects were 128 healthy Japanese men (20-97 years old). Bone microstructure was measured in the distal radius and tibia using second-generation HR-pQCT; aBMD in the proximal femur and lumbar spine was measured with DXA; and tartrate-resistant acid phosphatase-5b (TRACP-5b), type I procollagen-N-propeptide (P1NP), 25(OH) vitamin D, and pentosidine concentrations were measured by blood tests. RESULTS In trabecular bone, the trabecular volumetric BMD (Tb.vBMD) and trabecular number (Tb.N) were lower with age (r = -0.23, -0.35) (r = -0.36,-0.33), and trabecular separation (Tb.Sp) and the star volume of marrow space (V*ms) were higher with age (r = 0.29, 0.41) (r = 0.34, 0.38) in both the radius and tibia. In cortical bone, cortical volumetric BMD (Ct.vBMD) was lower with age (r = -0.25, -0.52), and cortical porosity (Ct.Po) was higher with age (r = 0.67, 0.62) in both the radius and tibia. In the tibia, cortical thickness (Ct.Th) and cortical area (Ct.Ar) were lower with age (r = -0.40) (r = -0.43), whereas, in the radius, they were maintained, and periosteal perimeter (Ct.Pm) was higher with age (r = 0.35). aBMD in the proximal femur and P1NP were lower, and pentosidine was higher with increased age, whereas aBMD in the lumbar spine, TRACP-5b, and 25(OH) vitamin D had no relationships with age. DXA and HR-pQCT showed strong correlations particularly with femoral aBMD and tibial Tb.vBMD and Ct.Ar (r = 0.61) (r = 0.61), whereas no DXA parameters were related with Ct.Po. In correlations between biochemical markers and HR-pQCT, TRACP-5b and total P1NP were negatively correlated with Ct.vBMD (r = -0.31) (r = -0.35), but almost no other correlations were seen. CONCLUSIONS Age-related changes of the bone microstructure in men were characterized by decreases in trabecular and cortical vBMD associated with decreased trabecular number, cavitation of the trabecular structure, and increased cortical porosity. Femoral aBMD was strongly related to bone microstructure in the tibia, whereas both lumbar aBMD and femoral aBMD were not related to Ct.Po, and biochemical markers showed almost no relationships with bone microstructure.

Abstract
PURPOSE Regarding epidemiological studies, the role of vitamin D in musculoskeletal functionality (muscle weakness and physical performance) among elderly people is still controversial. The purpose of the present study was to investigate the associations between 25-hydroxyvitamin D [25(OH)D] and physical performance among community-dwelling middle-aged and old Japanese men and women. METHODS The subjects were community-dwelling 297 men and 415 women aged 50 years and over. Data on height (m) and weight (kg) were collected. Serum 25(OH)D, parathyroid hormone, calcium, and albumin levels were measured. Serum 25(OH)D was classified into deficiency group: < 20 ng/mL, insufficiency group: 20-30 ng/mL, and sufficiency group: ≧ 30 ng/mL. Physical performance was assessed by grip strength, chair stand time, and functional reach. Information on current smoking, alcohol drinking, regular exercise, any comorbidities (hypertension, heart disease, diabetes mellitus, lung disease, and stroke), and pain (lumbar and knee) was collected. RESULTS Vitamin D deficiency and insufficiency based on serum 25(OH)D levels were observed in 15.2% and 56.9% of men and 52.0% and 43.6% of women, respectively. In men, higher serum 25(OH)D levels were associated with better grip strength (p for trend = 0.003), chair stand time (p for trend = 0.042), and functional reach (p for trend <0.001). On the other hand, these parameters were not associated with serum 25(OH)D levels in women. CONCLUSION A higher level of serum 25(OH)D was associated with better physical performance in men but not in women.

Abstract
Background Adequate levels of vitamin D are important for women of childbearing age as vitamin D helps maintain the pregnancy and ensures proper maternal and fetal bone metabolism and fetal skeletal development. However, vitamin D deficiency is a health problem prevalent in women of all ages, worldwide. This study aimed to determine the current status of serum vitamin D levels and the risk factors for vitamin D deficiency among South Korean nurses of childbearing age. Methods Serum levels of 25-hydroxyvitamin D (25[OH]D) were measured in 1594 registered nurses aged 20 to 45 years who are participants in an ongoing prospective cohort study of the Korean Nurses’ Health Study initiated in 2013. The participants completed surveys about demographic and occupational characteristics and physical and psychological health. We examined associations with vitamin D deficiency through multivariable logistic regression analysis. Results The average blood 25(OH) D concentration of the participants was 12.92 ng/mL (4.0–63.4 ng/mL), while the prevalence of vitamin D deficiency (< 20 ng/mL) was 89% (1419/1594). Multivariable logistic regression showed that significant risk factors for vitamin D deficiency included month of sampling (there was a lower level of vitamin D deficiency in winter than in spring, summer, or fall), age (women in their 20s had a lower vitamin D level than those in their 30s and 40s), and stress symptoms. Vitamin D levels were not associated with body mass index, physical activity, and depressive symptoms. Conclusions This study showed a high prevalence of vitamin D deficiency in Korean female nurses. Serum levels of vitamin D were associated with age and season. Vitamin D deficiency should be recognized as one of the primary health concerns among young women. More proactive actions, such as vitamin D supplements and food fortification, are needed to improve vitamin D deficiency in high-risk groups.

Nutr Metab Cardiovasc Dis 2021; 31:2792-2799. [PMID: 34332862 DOI: 10.1016/j.numecd.2021.06.007] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 06/11/2021] [Accepted: 06/11/2021] [Indexed: 01/11/2023]
Abstract
AIMS A comprehensive assessment of the association of shift work with risk of metabolic syndrome (MetS) through a systematic review and meta-analysis has not been reported. We aimed to evaluate the relationship from observational studies. DATA SYNTHESIS We searched PubMed, Embase, and Web of Science databases from inception to December 16, 2020. Articles were chosen according to established inclusion criteria. Studies with data on men and women and different types of shift work were treated as independent studies. Relative risks (RRs) and 95% confidence intervals (CIs) were pooled by using random-effects models with heterogeneity (I2) > 50%; otherwise, a fixed-effects model was used. A total of 7192 articles was searched from PubMed, Embase and Web of science. Finally, we included 23 articles (38 studies) in this meta-analysis. The pooled RRs and 95% CI of MetS risk with shift work, 1-shift work, 2-shift work, and 3-shift work versus non-shift work were 1.30 (95% CI 1.19-1.41), 0.95 (95% CI 0.82-1.11), 1.19 (95% CI 0.91-1.56) and 1.17 (95% CI 1.00-1.37), respectively. The results from subgroup analyses stratified by sex, age, and region supported our overall findings that shift work is a risk factor for MetS. CONCLUSIONS This meta-analysis suggests that shift work increases risk of MetS. Higher risk of MetS was found in the shift workers who were 2-shift or 3-shift or women or Asian workers.

Abstract
UNLABELLED We showed an association between serum concentrations of vitamin D and bone health among community-dwelling adults in Japan after adjustment for confounding factors, with 730 participants in a city, with concentrations of 25(OH) vitamin D, and with parameters of quantitative ultrasound. PURPOSE The primary objective of this study was to examine the correlation between serum 25-hydroxyvitamin D (25(OH)D) concentration and bone indicators as measured by quantitative ultrasound in middle-aged and older Japanese adults living in low-latitude seaside areas during summer and autumn. METHODS We conducted a cross-sectional study, the Unzen study, on community-dwelling Japanese adults who participated to periodic health examinations between 2011 and 2013 (during the months of May to November). RESULTS A total of 301 men (mean (SD) age, 67.9 (8.2) years; range, 50-92 years) and 429 women (mean (SD) age, 67.9 (7.7); range, 50-89 years) participated in this study. Serum 25(OH)D levels and quantitative ultrasound parameters (broadband ultrasound (BUA), speed of sound (SOS), and stiffness index of the calcaneus were measured for the participants. We excluded two men and 28 women from the 730 participants because they were on medication for osteoporosis. So, 299 men and 401 women were included in the final data analysis. The prevalence of vitamin D insufficiency (< 30 ng/ml) was very high: 71.9% in men and 95.5% in women. In women, the log(25(OH)D) positively and significantly correlated with SOS (p = 0.011) and stiffness index (p = 0.028) but not with BUA (p = 0.176). In men, the log(25(OH)D) did not correlate with the BUA, SOS, or stiffness index (p = 0.218, 0.420, and 0.262, respectively). CONCLUSIONS Serum 25(OH)D levels were associated with SOS or stiffness index in women but not in men.

Impact of serum vitamin D on the response and prognosis in breast cancer patients treated with neoadjuvant chemotherapy. Breast Cancer 2021; 29:156-163. [PMID: 34487328 PMCID: PMC8732931 DOI: 10.1007/s12282-021-01292-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 08/31/2021] [Indexed: 11/10/2022]
Abstract
Background Several studies have recently reported that the relationships between serum vitamin D and the prognosis or the pathological response to neoadjuvant chemotherapy (NAC) in breast cancer. However, there are no data regarding the clinical impacts of the vitamin D in Japanese breast cancer patients so far. Patients and methods In the present study, a total of 250 patients with clinical Stage I–III primary breast cancer who were treated with NAC and subsequently underwent definitive surgery were included. Serum 25-hydroxvitamin D (25(OH)D) levels were evaluated using blood samples obtained before NAC. Results The serum 25(OH)D was positively associated with age, and the serum 25(OH)D was significantly higher in postmenopausal women than that in pre/peri-menopausal women. Serum 25(OH)D level was not associated with the achievement of pathological complete response (pCR) in this cohort. The low 25(OH)D levels were significantly associated with shorter time to distant recurrence (TTDR). According to the univariate analysis, high clinical stage before NAC (cStage III) and low serum 25(OH)D level were significantly associated with the shorter TTDR, and pCR was significantly associated with the longer TTDR. According to a multivariate analysis, low serum 25(OH)D level were independent poor prognostic factors for TTDR. Conclusions The low 25(OH)D levels were significantly associated with poorer prognosis in Japanese women with operable breast cancer patients treated with NAC.

Abstract
Objectives Vitamin D deficiency, which is common worldwide, increases the risks of falls and fractures and can lead to increased morbidity and mortality. However, the clinical utility and relevance of vitamin D activation remain unknown. The aim of the present study was to clarify the clinical usefulness of serum 1,25-dihydroxyvitamin D (1,25D)/25-hydroxyvitamin D (25D) ratio for assessment of the extent of bone metabolism. Methods We retrospectively screened data for 87 patients whose serum 1,25D and 25D levels were measured. Eight patients who were taking vitamin D preparations were excluded, and data for 79 patients (33 males and 46 females) were analyzed. Since menopausal status can be associated with serum vitamin D level, we divided the patients by gender and divided the female patients into two groups at the age of 50 years. Results The median serum 1,25D/25D ratio was significantly lower in males than in females, with the most considerable difference in all males [4.1 (interquartile range: 2.3-5.8) × 10-3] versus elderly females (aged ≧50 years) [7.9 (3.3-10.1) × 10-3). Main disorders were endocrine (30.6%), inflammatory (18.5%), and bone-related (16.7%) disorders. The ratios of serum 1,25D/25D had significant negative correlations with femoral dual-energy X-ray absorptiometry % young adult mean (DEXA %YAM) (R=-0.35) and lumbar DEXA %YAM (R=-0.32). Significant correlations were found between the 1,25D/25D ratio and serum levels of inorganic phosphate (iP), parathyroid hormone, and alkaline phosphatase (ALP). The 1,25D/25D ratio had gender-specific characteristics: the ratio was significantly correlated with age in males (R=-0.49), while it was significantly correlated with BMI in females (R=0.34). Conclusions The results of this study suggested that vitamin D activity is negatively correlated with bone mineral density, being reduced in aged males but enhanced in obese females.

Abstract
AIMS/INTRODUCTION Type 1 diabetes is associated with poorer bone quality. Quantitative ultrasound provides an estimate of bone mineral density (BMD) and can also be used to evaluate bone quality, which is associated with an increased fracture risk in people with type 1 diabetes. The aim of this study was to evaluate the association between menopausal status and a bone turnover marker with heel BMD using quantitative ultrasound in women with type 1 diabetes and age- and body mass index-matched controls. MATERIALS AND METHODS A total of 124 individuals recruited in Kyoto and Osaka, Japan - 62 women with type 1 diabetes (mean age 47.2 ± 17.3 years) and 62 age-, menopausal status-, sex- and body mass index-matched non-diabetic control individuals (mean age 47.3 ± 16.3 years) - were enrolled in this study. Heel BMD in the calcaneus was evaluated using ultrasonography (AOS-100NW, Hitachi-Aloka Medical, Ltd., Tokyo, Japan). A bone turnover marker was also measured. RESULTS The heel BMD Z-score was significantly lower in premenopausal women with type 1 diabetes than in the premenopausal control group, but not in postmenopausal women with type 1 diabetes. Levels of tartrate-resistant acid phosphatase-5b, a bone resorption marker, were significantly higher in premenopausal women with type 1 diabetes than in the premenopausal control group, but not in postmenopausal women with type 1 diabetes. The whole parathyroid hormone level was significantly lower in both pre- and postmenopausal women with type 1 diabetes. CONCLUSIONS Lower heel BMD, higher tartrate-resistant acid phosphatase-5b level and lower parathyroid hormone were observed in premenopausal women with type 1 diabetes. Premenopausal women with type 1 diabetes require osteoporosis precautions for postmenopause.

Abstract
PURPOSE The Westlake BioBank for Chinese (WBBC) pilot cohort is a population-based prospective study with its major purpose to better understand the effect of genetic and environmental factors on growth and development from adolescents to adults. PARTICIPANTS A total of 14 726 participants (4751 males and 9975 females) aged 14-25 years were recruited and the baseline survey was carried out from 2017 to 2019. The pilot cohort contains rich range of information regarding of demographics and anthropometric measurements, lifestyle and sleep patterns, clinical and health outcomes. Visit the WBBC website for more information (https://wbbc.westlake.edu.cn/index.html). FINDINGS TO DATE The mean age of the study samples were 18.6 years for males and 18.5 years for females, respectively. The mean height and weight were 172.9 cm and 65.81 kg for males, and 160.1 cm and 52.85 kg for females. Results indicated that the prevalence of underweight in female was much higher than male, but the prevalence of overweight and obesity in female was lower than male. The mean serum 25(OH)D level in the 14 726 young participants was 22.4±5.3 ng/mL, and male had a higher level of serum 25(OH)D than female, overall, 33.5% of the participants had vitamin D deficiency and even more participants suffered from vitamin D insufficiency (58.2%). The proportion of deficiency in females was much higher than that in males (41.8 vs 16.4%). The issue of underweight and vitamin D deficiency in young people should be paid attention, especially in females. These results reflected the fact that thinness and paler skin are preferred in modern aesthetics of Chinese culture. FUTURE PLANS WBBC pilot is designed as a prospective cohort study and provides a unique and rich data set analysing health trajectories from adolescents to young adults. WBBC will continue to collect samples with old age.

Abstract
A 48-year-old woman with a 9-year-history of anorexia nervosa (AN) was admitted complaining of generalized bone pain. Blood tests showed hypocalcemia and hyperphosphatasemia, and a radiological survey revealed multiple rib fractures, suggesting complication with osteomalacia. Two years earlier, she had undergone subtotal colectomy for colon cancer. Her serum 25-hydroxy vitamin D concentration was below the detectable level. In addition to a poor nutritional intake and insufficient sun exposure, malabsorption of fat-soluble substances in the intestine and phosphate loss from the kidneys might have contributed to the development of her osteomalacia.

Abstract
INTRODUCTION The incidence rate of vitamin D deficiency is increasing throughout the world. We measured the incidence rate of vitamin D deficiency and fibroblast growth factor 23 (FGF23) levels in 12- to 13-year-old adolescents in Japan. MATERIALS AND METHODS A total of 492 adolescents (247 boys and 245 girls) from Japanese community enrolled in this study. 25 hydroxyvitamin D (25(OH)D) was measured with radioimmunoassay. In the subjects with low 25(OH)D levels (≦ 20 ng/ml), intact parathyroid hormone (iPTH), calcium (Ca), phosphorus (P), albumin (Alb), alkaline phosphatase (ALP) and FGF23 were measured. RESULTS 25(OH)D levels were significantly lower in girls (20.9 ± 3.1 ng/ml) than in boys (22.2 ± 3.3 ng/ml) (p < 0.0001). Fifty-five boys (22.3%) and 83 (33.9%) girls showed vitamin D deficiency (< 20 ng/ml). One-hundred eighty-six (75.3%) boys and 162 (66.1%) girls showed vitamin D insufficiency (≧ 20 ng/ml, < 30 ng/ml). In the subjects whose 25(OH)D levels were ≦ 20 ng/ml, the levels of iPTH, Ca, P, Alb, ALP and FGF23 were 22.3 ± 9.0 pg/ml, 9.5 ± 0.4 mg/dl, 4.7 ± 0.6 mg/dl, 4.6 ± 0.3 g/dl, 920.8 ± 339.3 U/l and 42.6 ± 26.0 pg/ml, respectively. There was a significant negative association between serum 25(OH)D levels and iPTH [r = - 0.290 (p < 0.0001)]. There was no significant association between serum 25(OH)D levels and FGF23. CONCLUSION We show that 28% of Japanese 12- to 13-year-old early adolescents suffer from vitamin D deficiency. Findings from this study indicate that vitamin D deficiency requires close oversight in public health during adolescence to ensure proper bone health.

Abstract
Vitamins D have various biological activities, as well as intestinal calcium absorption. There has been recent concern about insufficient vitamin D intake. In addition to vitamins D2 and D3, there are lesser-known vitamins D4–D7. We synthesized vitamins D5–D7, which are not commercially available, and then evaluated and compared the mixed micelles-solubilized vitamins D uptake by Caco-2 cells. Except for vitamin D5, the uptake amounts of vitamins D4–D7 by differentiated Caco-2 cells were similar to those of vitamins D2 and D3. The facilitative diffusion rate in the ezetimibe inhibited pathway was approximately 20% for each vitamin D type, suggesting that they would pass through the pathway at a similar rate. Lysophosphatidylcholine enhanced each vitamin D uptake by approximately 2.5-fold. Lysophosphatidylcholine showed an enhancing effect on vitamin D uptake by reducing the intercellular barrier formation of Caco-2 cells by reducing cellular cholesterol, suggesting that increasing the uptakes of vitamins D and/or co-ingesting them with lysophosphatidylcholine, would improve vitamin D insufficiency. The various biological activities in the activated form of vitamins D4–D7 were estimated by Prediction of Activity Spectra for Substances (PASS) online simulation. These may have some biological activities, supporting the potential as nutritional components.

Recommendations on the measurement and the clinical use of vitamin D metabolites and vitamin D binding protein - A position paper from the IFCC Committee on bone metabolism. Clin Chim Acta 2021; 517:171-197. [PMID: 33713690 DOI: 10.1016/j.cca.2021.03.002] [Citation(s) in RCA: 28] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 01/10/2021] [Accepted: 03/04/2021] [Indexed: 02/08/2023]
Abstract
Vitamin D, an important hormone with a central role in calcium and phosphate homeostasis, is required for bone and muscle development as well as preservation of musculoskeletal function. The most abundant vitamin D metabolite is 25-hydroxyvitamin D [25(OH)D], which is currently considered the best marker to evaluate overall vitamin D status. 25(OH)D is therefore the most commonly measured metabolite in clinical practice. However, several other metabolites, although not broadly measured, are useful in certain clinical situations. Vitamin D and all its metabolites are circulating in blood bound to vitamin D binding protein, (VDBP). This highly polymorphic protein is not only the major transport protein which, along with albumin, binds over 99% of the circulating vitamin D metabolites, but also participates in the transport of the 25(OH)D into the cell via a megalin/cubilin complex. The accurate measurement of 25(OH)D has proved a difficult task. Although a reference method and standardization program are available for 25(OH)D, the other vitamin D metabolites still lack this. Interpretation of results, creation of clinical supplementation, and generation of therapeutic guidelines require not only accurate measurements of vitamin D metabolites, but also the accurate measurements of several other "molecules" related with bone metabolism. IFCC understood this priority and a committee has been established with the task to support and continue the standardization processes of vitamin D metabolites along with other bone-related biomarkers. In this review, we present the position of this IFCC Committee on Bone Metabolism on the latest developments concerning the measurement and standardization of vitamin D metabolites and its binding protein, as well as clinical indications for their measurement and interpretation of the results.

A high-fat diet in the presence of vitamin D deficiency status is associated with a negative influence on calcaneal quantitative ultrasound parameters in young adults: a cross-sectional study. Nutr Res 2021; 86:88-95. [PMID: 33551259 DOI: 10.1016/j.nutres.2020.12.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2020] [Revised: 11/09/2020] [Accepted: 12/02/2020] [Indexed: 10/22/2022]
Abstract
Vitamin D deficiency and a high-fat diet are considered health problems worldwide. The aims of this study were to examine the prevalence of vitamin D deficiency/insufficiency in young adults, factors related to the vitamin D status, and the influence of vitamin D deficiency and/or a high-fat diet on bone parameters. Here, we investigated the hypothesis that a high-fat diet in the presence of a vitamin D-deficient status would have a more negative influence on bone parameters than a normal-fat diet with such a status. In the present study, we targeted young Japanese adults aged 21-23 (n = 175). We conducted a diet survey based on 3-day food records, biochemical examination of serum, and quantitative ultrasound measurements at the calcaneus. As a result, the rates of vitamin D deficiency {serum 25-hydroxyvitamin D3 [25(OH)D] concentration less than 20 ng/mL} and insufficiency [serum 25(OH)D concentration less than 30 ng/mL but not less than 20 ng/mL] were 60.6 and 30.9%, respectively. A positive correlation was observed between the serum 25(OH)D level and serum bone-specific alkaline phosphatase level, which is a serum marker of bone formation (r = 0.253, P< .01) or the speed of sound (SOS) as an index of bone density (r = 0.259, P< .01). A negative correlation was observed between the ratio of fat intake to total energy intake (%E) and serum 25(OH)D levels (r = -0.206, P< .01). Furthermore, we revealed that a high-fat diet in the presence of a vitamin D deficient status reduced the SOS parameter compared with a normal-fat diet with a vitamin D-deficient status (P< .05).

Abstract
OBJECTIVES We aimed to determine serum 25-hydroxyvitamin D (25(OH)D) and undercarboxylated osteocalcin (ucOC) levels in severe motor and intellectual disabilities (SMID) patients and their association with bone turnover biomarkers. METHODS We assessed vitamin D and K levels as indicators of osteoporosis in institutionalized adults with SMID. From December 2019 to February 2020, 93 institutionalized patients (48 men, 45 women; median age, 49 years) underwent annual routine examinations. Serum ucOC, 25(OH)D, bone-specific alkaline phosphatase (BAP), and tartrate-resistant acid phosphatase A 5b (TRACP-5b) levels as bone formation and resorption markers and calcium and phosphorous levels were measured. Vitamin K deficiency was indirectly assessed based on ucOC levels. RESULTS Mean ucOC levels were higher than normal (i.e., vitamin K deficiency). Serum 25(OH)D levels were markedly diminished. Overall, 86% of patients had deficient 25(OH)D levels. These 25(OH)D-deficient patients had higher ucOC levels. Multiple linear regression analysis revealed an inverse correlation between 25(OH)D and ucOC levels. ucOC levels were significantly higher and 25(OH)D levels were significantly lower in tube feeding. TRACP-5b levels were significantly higher in elderly than in young women. BAP and TRACP-5b levels were normal in adults. No relationship existed between vitamin D and antiepileptic drug use. CONCLUSIONS Vitamin K and D co-deficiency was common in SMID patients. Vitamin K and D deficiencies were worse in tube-fed patients than in oral intake patients. SMID patients should undergo regular monitoring of vitamin D and K levels and supplementation of these vitamins.

Abstract
OBJECTIVE To clarify whether there are any muscle synergy changes in individuals with knee osteoarthritis, and to determine whether muscle synergy analysis could be applied to other musculoskeletal diseases. METHODS Subjects in this study included 11 young controls (YC), 10 elderly controls (EC), and 10 knee osteoarthritis patients (KOA). Gait was assessed on a split-belt treadmill at 3 km/h. A non-negative matrix factorization (NNMF) was applied to the electromyogram data matrix to extract muscle synergies. To assess the similarity of each module, we performed the NNMF analysis assuming four modules for all of the participants. Further, we calculated joint angles to compare the kinematic data between the module groups. RESULTS The number of muscle modules was significantly lower in the EC (2-3) and KOA (2-3) groups than in the YC group (3-4), which reflects the merging of late swing and early stance modules. The EC and KOA groups also showed greater knee flexion angles in the early stance phase. Contrarily, by focusing on the module structure, we found that the merging of early and late stance modules is characteristic in KOA. CONCLUSION The lower number of modules in the EC and KOA groups was due to the muscle co-contraction with increased knee flexion angle. Contrarily, the merging of early and late stance modules are modular structures specific to KOA and may be biomarkers for detecting KOA. SIGNIFICANCE Describing the changes in multiple muscle control associated with musculoskeletal degeneration can serve as a fundamental biomarker in joint disease.

Abstract
Vitamin deficiency causes classical deficiency diseases such as beriberi and rickets. Vitamin insufficiency, which is milder than deficiency, is a risk for various chronic diseases, but its significance has not been recognized in Japan. Vitamin D insufficiency is quite common in Japan, and a serious risk for osteoporotic fracture through its unbeneficial effect on bone and muscle. Insufficiency of B vitamins has been little studied. However, hyperhomocysteinemia caused by the insufficiency of vitamin B12 or folate is a risk for cardiovascular disease, osteoporotic fracture, and cognitive impairment. Additionally, we have recently reported that vitamin B1 insufficiency is a risk for heart failure in the elderly. The effect of improvement of nutritional status including vitamins is less marked compared to drug treatment, but it costs far less, and is suited for the primary prevention of diseases. Randomized controlled trial is considered the study with the most robust evidence in the evaluation of drug treatment, but more emphasis should be put on the well-designed cohort studies in evaluating the role of nutrients. Vitamin insufficiency is quite prevalent, and vitamin requirement is much higher for its prevention than for the prevention of deficiency.

Abstract
Background Vitamin D deficiency has been often observed in obese persons. One of the mechanisms suggested for low vitamin D status in obesity was decreased bioavailability of vitamin D (VD) due to sequestration in adipose tissue. However, only few studies have investigated this mechanism via quantifying vitamin D levels from tissues from the obese. Methods Six-wk-old C57BL/6 mice were fed 10 or 45% kcal fat (CON or HFD) diets containing 50, 1000 or 25,000 IU vitamin D3/kg diet (LVd, CVd or HVd) for 13 wks. Serum 25-hydroxyvitamin D (25(OH)D) levels were determined by radioimmunoassay and liver and adipose tissue cholecalciferol (VD3) and 25-hydrocholecalciferol (25(OH)D3) levels were measured by LC-MS/MS. mRNA levels of jejunal Mttp, Cd36, Sr-b1, Npc1l1, and Abca1 and liver and adipose tissue 25-hydroxylases (Cyp2r1 and Cyp27a1) were determined by real-time PCR. Results Serum 25(OH)D levels were affected by dietary vitamin D content but differential effects were observed between HFD and CON groups. When vitamin D intake was at a supplementary level, the HFD-HVd group had lower serum 25(OH)D levels than the CON-HVd group, while there was no significant difference between the HFD and CON groups fed LVd or CVd. Total amount of VD3 in liver and adipose tissue were significantly higher in HFD-HVd group compared with the CON-HVd group. However, no difference in total amount of tissue VD3 was observed between the CON and HFD groups fed CVd. In jejunum, mRNA levels of Mttp and Abca1 were significantly higher in HFD groups than CON groups. There was no difference in mRNA levels of liver 25-hydroxylases by both dietary fat amount and vitamin D content. Conclusion A significant amount of VD3 seemed to be stored in the liver and adipose tissue when dietary vitamin D is at a supplementation level; thus excess body adiposity could contribute to relatively low serum 25(OH)D level when vitamin D was supplemented.

Abstract
Background Vitamin D insufficiency is widespread in China. Various factors influence vitamin D level in the body. The present study investigated vitamin D status of residents in Jinzhong city, China, and analyzed the influence of gender on vitamin D status. Material/Methods In this cross-sectional study, 302 participants (176 men and 126 women) were recruited. Anthropometric data (body circumferences and height, weight) were collected, and serum vitamin D concentration was tested. Results Inadequate levels of vitamin D were found in 69% of men and 75% of women. Women’s 25(OH)D level (38.40±12.37 nmol/l) was substantially lower than that of the men (43.49±14.78 nmol/l) (p<0.01). The young women group had the lowest vitamin D level, which was even significantly below that of the elderly women group. Multiple linear regression analysis showed gender was significantly associated with vitamin D status (p<0.01). Conclusions Vitamin D deficiency is common in residents of Jinzhong during the winter. Compared to men, women are more prone to have inadequate vitamin D levels.

Abstract
Vitamin D deficiency (VDD) is associated with an increased risk of various diseases. Serum 25-hydroxyvitamin D [25(OH)D] concentration is the best marker for vitamin D status and its concentration < 20 ng/mL indicates VDD. However, its measurement is not easily applicable for the evaluation of vitamin D status in the general population because of its cost. Therefore, we aimed to develop a simple questionnaire for easily identifying the risk of VDD. From the total sample (649 healthy subjects aged 19-70 years), 434 and 215 subjects were randomly assigned to the derivation and the validation cohort, respectively. Prediction model for VDD was developed by backward logistic regression analysis. The regression β coefficients of the significant predictors were transformed into integral numbers and used for the individual score. These individual scores were summed to calculate the total risk score (VDD questionnaire for Japanese score: VDDQ-J score). VDD was present in 54.1% of the total subjects. The model for the prediction of VDD consisted of 7 predictors. Areas under the curve were 0.78 and 0.75 in the data set of internal validation and of the external validation, respectively. The cutoff value was determined to be 31 points (range 0-54) with the sensitivity/specificity and positive predictive value/negative predictive value of 61%/79%, and 81%/57%, respectively. Our VDDQ-J score is easy to answer by the wide range of subjects, and well predicts VDD. This risk score would be useful to identify subjects at risk for VDD both in clinical and epidemiological settings.

Abstract
Adolescent idiopathic scoliosis (AIS) is the most common pediatric spinal deformity. Several AIS susceptibility loci have been identified; however, they could explain only a small proportion of AIS heritability. To identify additional AIS susceptibility loci, we conduct a meta-analysis of the three genome-wide association studies consisting of 79,211 Japanese individuals. We identify 20 loci significantly associated with AIS, including 14 previously not reported loci. These loci explain 4.6% of the phenotypic variance of AIS. We find 21 cis-expression quantitative trait loci-associated genes in seven of the fourteen loci. By a female meta-analysis, we identify additional three significant loci. We also find significant genetic correlations of AIS with body mass index and uric acid. The cell-type specificity analyses show the significant heritability enrichment for AIS in multiple cell-type groups, suggesting the heterogeneity of etiology and pathogenesis of AIS. Our findings provide insights into etiology and pathogenesis of AIS. Adolescent idiopathic scoliosis (AIS) is a common pediatric disease leading to spinal deformities. Here, the authors report GWAS followed by genome-wide meta-analysis in up to 79,211 Japanese individuals, identifying 20 genetic loci for AIS, 14 of which were previously unreported, and perform in vitro validation for rs1978060.

Abstract
Background Hypovitaminosis D is prevalent worldwide. It is more prevalent in Eastern Asia region, including Korea. In addition to various environmental factors that influence serum 25-hydroxyvitamin D (25(OH)D) concentration, genetic influence also plays a significant role based on studies estimating the heritability of 25(OH)D in non-Asian populations. The objective of this study was to determine the genetic influence on serum 25(OH)D concentration in Korean men using the twin and family data. Methods A total of 1126 Korean male adult twins and family members from the Healthy Twin Study with serum 25(OH)D measurement were included in this cross-sectional study. Intraclass correlation coefficients (ICCs) and heritability were calculated by mixed linear regression analysis and quantitative genetic analysis after adjusting for environmental and lifestyle factors. Results Mean (± standard deviation; SD) of serum 25(OH)D concentration was 15.34 ± 6.18 ng/ml. The prevalence of vitamin D insufficiency was 19.8% and that of vitamin D deficiency was 77.9%. After adjusting for age, the highest ICC (0.61) was observed for monozygotic twin pairs while the lowest ICC (0.31) was found for father-son pairs. Age-adjusted heritability was estimated to be 58%. When physical activity, multivitamin intake and season of blood sampling were further considered, the ICC and heritability did not materially change. In the sensitivity analysis after excluding known multivitamin users, age-adjusted heritability was reduced to 44%. Conclusions In our study of Korean male twins and family members, heritability of 25(OH)D was moderately high. This supports the finding that genetic factors have significant influence on vitamin D status.

Abstract
Populations of East Asian countries have been known to have low calcium intakes and low serum 25(OH)D concentrations, suggesting that Ca and vitamin D (VitD)-deficiencies are commonly observed. These nutritional imbalances may lead to low peak bone mass (PBM). The low PBM seen in Ca/VitD-deficient individuals may lead to osteoporosis, as well as an increased risk of fracture. A survey was conducted in young Japanese women (n = 296, 21.2 ± 2.3 years old) on their Ca/VitD intakes and serum 25(OH)D levels, which demonstrated a significant positive correlation between VitD intake and serum 25(OH)D levels (R 2 = 0.020, P = 0.016), and the proportion with serum 25(OH)D over 20 ng/mL was significantly increased with VitD intake (P = 0.013). Serum 25(OH)D was negatively correlated to serum intact parathyroid hormone (R 2 = 0.053, P < 0.001). On receiver operating characteristic curve analysis, the VitD intake threshold for maintaining 25(OH)D levels at 20 ng/mL or higher was 11.6 μg/day or greater. It was suggested that the recommended VitD intake allowance, defined in the Adequate Intakes as 5.5 μg/day, may not be sufficient to maintain serum 25(OH)D levels for bone health.

Abstract
Vitamin D deficiency has become one of the most prevalent health problems in modern society. However, there has been no study that has reported the trend of vitamin D status in Asia. We performed an observational study to investigate the trend of vitamin D status in South Korea based on a representative national database acquired from the Korea National Health and Nutrition Examination Surveys (KNHANES) conducted from 2008 to 2014. A total of 39,759 patients were included in the final analyses. Serum 25-hydroxyvitamin D (25 (OH)D) levels were measured by radioimmunoassay. The overall mean serum level of 25 (OH)D was 45.7 nmol/L in males and 40.9 nmol/L in females in KNHANES 2008 to 2014. There was a significant trend toward lower serum 25 (OH)D levels from 2008 to 2014 in males by -1.2 (95% confidence interval [CI] -1.5 to -0.9) nmol/L per year and in female by -0.7 (95% CI -0.9 to -0.4) nmol/L per year. The overall mean serum level of 25 (OH)D in 2008 was 53.0 nmol/L in males and 45.7 nmol/L in females. It decreased to 43.2 nmol/L in males and 39.2 nmol/L in females in 2014. Vitamin D deficiency, defined as the serum 25 (OH)D level of <50 nmol/L, was found in 65.7% of males and 76.7% of females in overall population. A significant increasing trend of vitamin D deficiency was also observed. The prevalence of vitamin D deficiency in 2008 was 51.8% in males and 68.2% in females, but rose to 75.2% and 82.5%, respectively, in 2014. The present study demonstrated that vitamin D status in South Koreans is still deteriorating. More extensive and proactive measures are needed to improve vitamin D status in South Korea.

J Bone Metab 2017; 24:141-145. [PMID: 28955689 PMCID: PMC5613018 DOI: 10.11005/jbm.2017.24.3.141] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2017] [Accepted: 06/07/2017] [Indexed: 12/31/2022] Open
Abstract
An adequate supply of vitamin D is considered necessary for osteoporosis management and fracture prevention. Intermittent high-dose vitamin D supplementation is an effective and convenient way to achieve and maintain sufficient vitamin D status. However, the long-term effectiveness of supplementation for preventing falls and fractures is unclear, and some deleterious effects of such treatments have been reported. Concerning these issues, the Korean Society for Bone and Mineral Research task force team reviewed previous clinical trials and provided the following perspectives based on current evidence: 1) An adequate supply of vitamin D is necessary for preventing falls and fractures in postmenopausal women and men older than 50 years. An oral intake of 800 to 1,000 IU/day of vitamin D is generally recommended. 2) Care should be taken concerning the routine use of intermittent high-dose vitamin D, as large-scale clinical trials showed increased risk of falls or fractures after high-dose vitamin D administration. Intermittent high-dose vitamin D supplementation is recommendable only in cases of malabsorption or when oral administration is not suitable. 3) Monitoring of the serum level of 25-hydroxy-vitamin D (25[OH]D) is advisable, especially when intermittent high-dose vitamin D is used for supplementation. The task force team suggests that a serum 25(OH)D level of >20 ng/mL is generally appropriate for the prevention of osteoporosis, and that a serum 25(OH)D level of >30 ng/mL is probably helpful both for the management of osteoporosis and the prevention of fractures and falls. However, serum 25(OH)D level >50 ng/mL (this value can vary depending on the measurement method used) is unnecessary and may be undesirable. These perspectives are relevant for the management of osteoporosis, falls, or fractures. Other metabolic bone diseases or non-skeletal disorders are not within the scope of these perspectives.

[PMID: 28243705 DOI: 10.1007/s00198-017-3967-6] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2016] [Accepted: 02/12/2017] [Indexed: 12/31/2022]
Abstract
UNLABELLED We found that community-dwelling women with 25-hydroxyvitamin D levels <20 ng/mL compared to levels ≥20 ng/mL indicated increased risks for clinical, non-vertebral, and fragility fractures during 5 years. Furthermore, the increased risks of non-vertebral fractures remained significant in 10 and 15 years after adjusting for age and bone mineral density. INTRODUCTION We examined whether total 25-hydroxyvitamin D (25[OH]D) levels are associated with fracture risk over 15 years in a Japanese female cohort. METHODS Of 1437 community-dwelling women aged ≥50 years in the baseline survey, 1236 provided information regarding fractures during a 15-year follow-up period. The analysis included 1211 women without early menopause or diseases affecting bone metabolism. RESULTS Over 15 years, 269 clinical (224 non-vertebral, 149 fragility) fracture events were confirmed. Incidence rates categorized by 25(OH)D levels (<10, 10-20, 20-30, and ≥30 ng/mL) indicated a significant divergence for any clinical fractures in 5 years (log rank test p = 0.016) and for non-vertebral fractures in 5, 10, and 15 years (p < 0.001, p = 0.001, p = 0.017, respectively). Hazard ratios (HRs) for 25(OH)D levels <10 and 10-20 ng/mL compared to levels ≥30 ng/mL during 5 years indicated significances for clinical fractures (HR 4.93 with p = 0.009, HR 3.00 with p = 0.034) and for non-vertebral fractures (HR 6.55 with p = 0.005, HR 3.49 with p = 0.036). Those with levels <20 ng/mL compared to those with levels ≥20 ng/mL indicated significant increased risks for clinical fractures (HR 1.72 with p = 0.010), non-vertebral fractures (HR 2.45 with p < 0.001), and fragility fractures (HR 2.00 with p = 0.032) in 5 years. The HR of non-vertebral fractures for levels <20 ng/mL remained significant during 15 years (HR 1.42 with p = 0.012) after adjustment for age and femoral neck bone mineral density. CONCLUSIONS Low 25(OH)D levels, especially <20 ng/mL, were associated with elevated fracture risks in Japanese women.

Abstract
Vitamin D is indispensable for the maintenance of bone and mineral health. Inadequate vitamin D action increases the risk for various musculoskeletal/mineral events including fracture, fall, secondary hyperparathyroidism, diminished response to antiresorptives, rickets/osteomalacia, and hypocalcemia. Its most common cause in recent years is vitamin D deficiency/insufficiency, clinically defined by low serum 25-hydroxyvitamin D [25(OH)D] level. Guidelines for vitamin D insufficiency/deficiency defined by serum 25(OH)D concentrations have been published all over the world. In Japan, however, the information on the associations between serum 25(OH)D and bone and mineral disorders has not been widely shared among healthcare providers, partly because its measurement had not been reimbursed with national medical insurance policy until August 2016. We have set out to collect and analyze Japanese data on the relationship between serum 25(OH)D concentration and bone and mineral events. Integrating these domestic data and published guidelines worldwide, here we present the following assessment criteria for vitamin D sufficiency/insufficiency/deficiency using serum 25(OH)D level in Japan. 1) Serum 25(OH)D level equal to or above 30 ng/mL is considered to be vitamin D sufficient. 2) Serum 25(OH)D level less than 30 ng/mL but not less than 20 ng/mL is considered to be vitamin D insufficient. 3) Serum 25(OH)D level less than 20 ng/mL is considered to be vitamin D deficient. We believe that these criteria will be clinically helpful in the assessment of serum 25(OH)D concentrations and further expect that they will form a basis for the future development of guidelines for the management of vitamin D deficiency/insufficiency.

Abstract
Objective There has been no prospective study that examined intramuscular injection of high-dose vitamin D in Korean adults. The aim of this study was to assess the efficacy and safety of high-dose vitamin D3 after intramuscular injection in Korean adults with vitamin D deficiency. Method This study was a 24-week, prospective, multicenter, randomized, double-blind, placebo-controlled trial. A total of 84 subjects ≥19 and <65 years of age were randomly allocated to either the vitamin D3 or placebo group in a 2:1 ratio. After randomization, a single injection of plain vitamin D3 200,000 IU or placebo was intramuscularly administered. If serum 25-hydroxyvitamin D (25[OH]D) concentrations were <30 ng/mL on week 12 or thereafter, a repeat injection was administered. Results After a single intramuscular injection of vitamin D3 to adults with vitamin D deficiency, the proportion of subjects with serum 25(OH)D concentrations ≥30 ng/mL within 12 weeks was 46.4% in the vitamin D3 group and 3.6% in the placebo group (p < 0.0001). The proportion of subjects with serum 25(OH)D concentrations ≥30 ng/mL within 24 weeks was 73.2% in the vitamin D3 group and 3.6% in the placebo group (p < 0.0001). Mean change in serum 25(OH)D concentrations at weeks 12 and 24 after vitamin D3 injection was 12.8 ± 8.1 and 21.5 ± 8.1 ng/mL, respectively, in the vitamin D3 group, with no significant changes in the placebo group. Serum parathyroid hormone concentrations showed a significant decrease in the vitamin D3 group but no change in the placebo group. Conclusion Intramuscular injection of vitamin D3 200,000 IU was superior to placebo in terms of its impact on serum 25(OH)D concentrations, and is considered to be safe and effective in Korean adults with vitamin D deficiency.

Abstract
Background: Low serum 25-hydroxyvitamin D [25(OH)D] and osteoarthritis (OA) are commonly found in patients followed up in a primary care office. Clear evidence to support the link between 25-hydroxyvitamin D levels and OA is lacking. Aim: To describe the association of serum 25-hydroxyvitamin D status in patients with OA in the primary care office. Materials and Methods: We reviewed the records of 1,455 patients seen in our primary care office between November 2013 and October 2014. All patients were older than 18 years and had a diagnosis of OA. Demographic characteristics as well as 25(OH)D levels and comorbidities were analyzed. Results: Levels of 25(OH)D were available in 1,222 patients with OA. Fifty-one percent of the patients had a low 25(OH)D level. Patients with OA and low 25(OH)D were on an average 5 years younger than patients with OA and normal 25(OH)D (P < 0.001). African Americans (71.7%) and Hispanics (63.1%) had a higher prevalence of low 25(OH)D compared to Whites (42.9%) and other races (49.1%) (P < 0.001). There were significantly more smokers (15.4%) and patients with type 2 diabetes (27.6%) in the group of patients with osteoarthritis and low 25(OH)D (P < 0.001). A lower prevalence of hypothyroidism (18.5% versus 27.4%) and higher body mass index (BMI) were also noted in the group of interest. Conclusion: Patients with low levels of 25(OH)D and OA are younger than their counterparts with low 25(OH)D level. Future studies are needed to clarify the relationship between 25(OH)D level and OA.

Abstract
BACKGROUND The fifth metatarsal bone is a common site of stress fractures in soccer athletes. Although several endocrine risk factors for stress fractures have been proposed, the endocrine risks for fifth metatarsal (5-MT) stress fractures have not been evaluated. METHODS To evaluate the endocrine risks of fifth metatarsal stress fractures, we conducted a cumulative case-control study. The present study included 37 athletes, of which 18 had a history of a zone 2 or zone 3 fifth metatarsal stress fracture and 19 controls. We analyzed serum 25-hydroxyvitamin D (25-OHD), serum parathyroid hormone (PTH), as well as biochemical markers of bone turnover by univariate or multivariate analyses. RESULTS Logistic regression analyses adjusted for multiple confounders revealed that insufficient serum 25-OHD levels less than 30 ng/mL (odds ratio [OR], 23.3), higher serum PTH levels (OR, 1.01), or higher serum bone-specific isoform of alkaline phosphatase levels (OR, 1.10) rather than serum tartrate-resistant acid phosphatase 5b were associated with statistically significantly increased odds of 5-MT stress fractures. A postestimation calculation demonstrated that 25-OHD levels of 10 and 20 ng/mL were associated with 5.1 and 2.9 times greater odds for 5-MT stress fractures, respectively. CONCLUSION 25-OHD insufficiency was associated with an increased incidence of 5-MT stress fractures. This insight may be useful for intervening to prevent 5-MT stress fractures. LEVEL OF EVIDENCE Level III, case-control study.

Osteoporos Int 2015; 26:2597-605. [PMID: 26089134 DOI: 10.1007/s00198-015-3184-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2014] [Accepted: 05/19/2015] [Indexed: 01/09/2023]
Abstract
UNLABELLED In this 3-year population-based cohort study, among 1346 subjects, the mean annual change in the serum 25-hydroxyvitamin D levels was 7.6 %/year, which tended to increase during the 3-year period. Multivariate regression analysis indicated that the L2-4 bone mineral density and total daily energy intake were significant independent associated factors. INTRODUCTION The aim of this study was to clarify the change rate of the serum levels of 25-hydroxyvitamin D (25D) and the associated factors in a general Japanese population during a 3-year period. METHODS The baseline survey of Research on Osteoarthritis/osteoporosis Against Disability study (ROAD), a large-scale population-based cohort study, was performed between 2005 and 2007, and a follow-up survey was repeated 3 years later. Among 1690 participants at baseline, the change rate of the serum 25D levels were assessed in 1346 individuals (79.6 %; 458 men and 888 women) who completed measurements of 25D at both the baseline and follow-up examinations. The change rate was calculated, and the factors associated with the changes in the 25D levels were determined using multivariate regression analysis after adjustment for age, gender, body mass index, participated month, and regional differences at baseline. RESULTS The mean (standard deviation) change rate of the 25D levels in all subjects was 7.6 (13.3) %/year (men, 8.2 [12.4] %/year; women, 7.3 [13.7] %/year). Multivariate regression analysis indicated that higher bone mineral density at lumbar spine L2-4 (p = 0.05) and total daily energy intake (p = 0.04) were significantly associated with the change rate of the 25D levels. CONCLUSIONS The serum levels of 25D tended to increase over the 3-year period, and higher lumbar bone mineral density and daily energy intake were found to be associated with increases in the 25D levels over time.

Impact of demographic, environmental, and lifestyle factors on vitamin D sufficiency in 9084 Japanese adults. Bone 2015; 74:10-7. [PMID: 25576673 DOI: 10.1016/j.bone.2014.12.064] [Citation(s) in RCA: 59] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2014] [Revised: 12/19/2014] [Accepted: 12/31/2014] [Indexed: 12/19/2022]
Abstract
BACKGROUND Little is known about correlates of vitamin D status in Asian populations. In this study, we established the prevalence of vitamin D sufficiency in the Murakami region (latitude N38°13') in Niigata, Japan, and examined demographic, environmental, and lifestyle factors that might be associated with vitamin D sufficiency, with the aim of clarifying the relative contributions of previously described determinants of vitamin D status as well as identifying new determinants in this Japanese population. METHODS This study involved a cross-sectional analysis of baseline data obtained from a cohort study conducted in 2011-2013. Participants were 9084 individuals aged between 40 and 74 years who provided blood samples for the determination of plasma 25-hydroxyvitamin D [25(OH)D] concentrations. Lifestyle information was obtained from 8498 participants, with some missing values regarding different lifestyle factors. Multiple logistic regression analysis was used to obtain odds ratios for vitamin D sufficiency, which was defined as a plasma 25(OH)D concentration ≥ 75 nmol/L. RESULTS The prevalence of vitamin D sufficiency (i.e., plasma 25(OH)D concentration ≥ 75 nmol/L) was 9.1%, and significant associations were observed with male gender (P<0.0001; OR=2.37, 95% CI: 1.84-3.05), older age (P for trend <0.0001), lower BMI (P for trend <0.0001), higher METs score (P for trend=0.0138), higher vitamin D intake (P for trend=0.0467), summer season (P for trend <0.0001), longer duration outdoors (P for trend=0.0026), no sunscreen use (P=0.0135; OR=1.40, 95% CI: 1.07-1.82), higher salmon consumption (P for trend <0.0001), higher alcohol consumption (P for trend <0.0001), and lower coffee consumption (P for trend=0.0025). Unlike other populations previously reported, vitamin D sufficiency was associated with older age. CONCLUSIONS The prevalence of vitamin D sufficiency (i.e., 25[OH]D ≥ 75 nmol/L) was low (9.1%) in this Japanese population. A number of demographic, environmental, and lifestyle factors are associated with vitamin D sufficiency, and thus lifestyle modification may present an opportunity to achieve vitamin D sufficiency.
