High maternal osteocalcin levels during pregnancy is associated with low birth weight infants: A nested case-control study in China
Low birth weight infants (LBW) are at risk of chronic diseases in later life due to the disorder of energy metabolism during pregnancy. Osteocalcin (OC) has been identified as a hormone that regulate energy metabolism. However, few studies have researched on the associations between maternal serum OC levels and low birth weight infants. (Source: Bone)

Pulsed electromagnetic fields modulate bone metabolism via RANKL/OPG and Wnt/ β-catenin pathways in women with postmenopausal osteoporosis: A pilot study
Pulsed electromagnetic fields (PEMFs) have been proven to enhance in vitro and in vivo osteogenesis with unknown mechanism. Aim of our study was to explore whether RANKL/OPG and Wnt/ β-Catenin pathways could be involved in bone response to PEMFs in a setting of postmenopausal osteoporotic women.Forty-three women (mean age 62.8 ± 4.5 yr.) were randomized into two groups. The PEMFs group received PEMFs treatment (50 min treatment session/day, 6 treatment sessions/week, f or a total of 25 times), by wearing a specific gilet applied to the trunk and connected to the electromagnetic device (Biosalus, by HSD Srl, Serra...

Dietary sugar intake does not pose any risk of bone loss and non-traumatic fracture and is associated with a decrease in all-cause mortality among Chinese elderly: Finding from an 11-year longitudinal study of Mr. and Ms. OS Hong Kong
The association of dietary sugar intake and skeletal health remains uncertain in the elderly. We aimed to investigate the association of sugar intake with the bone health and mortality of Chinese elderly. (Source: Bone)

Impact of aging on bone, marrow and their interactions
Hematopoiesis in land dwelling vertebrates and marine mammals occurs within the bone marrow, continually providing mature progeny over the course of an organism's lifetime. This conserved dependency highlights the critical relationship between these two organs, yet the skeletal and hematopoietic systems are often thought of as separate. In fact, data are beginning to show that skeletal disease pathogenesis influences hematopoiesis and viceversa, offering novel opportunities to approach disease affecting bone and blood.

Real-world effectiveness of teriparatide on fracture reduction in patients with osteoporosis and comorbidities or risk factors for fractures: Integrated analysis of 4 prospective observational studies
Teriparatide significantly reduces fracture rates in clinical trials; however, those study populations were relatively restricted and included too few patients to analyze fracture outcomes within clinically important patient subgroups. We assessed fracture outcomes in subgroups of osteoporosis patients from 4 real-world teriparatide observational studies. (Source: Bone)

Serum 25-hydroxyvitamin D and bone mineral density among children and adolescents in a Northwest Chinese city
Although vitamin D is essential for bone health, little is known about prevalence of vitamin D deficiency and low bone mineral density (BMD) among children, especially those in developing countries. It also remains unclear whether serum 25-hydroxyvitamin D [25(OH)D] is associated with BMD among children. We investigated these questions among children and adolescents in Yinchuan (latitude: 38 ° N), Ningxia, an economically underdeveloped province in Northwest China. A total of 1582 children (756 boys and 826 girls), aged 6–18 years, were recruited from schools using the stratified random sampling method in fall 2015. (Source: Bone)

Response to R. L. Nevin “Considerations in the repurposing of mefloquine for prevention and treatment of osteoporosis”
The authors would like to thank the reader for his interest in our article and his insightful feedback [1]. All of the points raised are important to take into consideration when looking at the possibility of using mefloquine to treat bone loss in aging. As correctly indicated by Dr. Nevin, the other members of the quinine family of drugs, but not mefloquine, have been used in humans to prevent skeletal complications. Our study was meant to be more of a proof of concept study based on the previous findings that other chloroquines effect bone mass. (Source: Bone)

Exploring the potential of tocotrienol from Bixa orellana as a single agent targeting metabolic syndrome and bone loss
This study aimed to investigate the effects of annatto tocotrienol as a single treatment for MetS and osteoporosis in high-carbohydrate high-fat (HCHF) diet-induced MetS animals. Three-month-old male Wistar rats were randomly divided into five groups. The baseline group was euthanized at the onset of the study. (Source: Bone)

The diagnostic threshold for osteoporosis impedes fracture prevention in women at high risk for fracture: A registry-based cohort study
The diagnostic threshold for osteoporosis, a bone mineral density (BMD) T-score  ≤ −2.5, signals an increased risk for fracture. However, most fragility fractures arise among the majority of women with ‘osteopenia’ or ‘normal’ BMD. We hypothesized that a BMD T-score of −2.5, even if not intended as a treatment threshold, paradoxically may create disincentive t o initiating treatment of women with osteopenia or normal BMD at high risk for fracture. From a population-based BMD registry covering the Province of Manitoba, Canada, we identified 3735 untreated women aged ≥ 50 years undergoing BMD screen...

Age trajectories of musculoskeletal morbidities in adults with cerebral palsy
Individuals with cerebral palsy (CP) are at an increased risk for age-related morbidities due to functional impairments, maladapted growth, and altered body composition. While musculoskeletal (MSK) deficits are present in children, little is understood about MSK morbidity throughout the lifespan in those with CP. The purpose of this study was to examine the age-related trajectories of MSK morbidity and multimorbidity throughout adulthood in those with CP. (Source: Bone)

Sleep disordered breathing and fibroblast growth factor 23 in the Hispanic Community Health Study/Study of Latinos
Preclinical data suggest that hypoxia stimulates fibroblast growth factor 23 (FGF23) transcription and cleavage in osteocytes, resulting in elevated circulating c-terminal (cFGF23) levels but normal intact FGF23 (iFGF23) levels. We conducted a case-control study within the Hispanic Community Health Study/Study of Latinos to investigate whether sleep disordered breathing, as a model of hypoxemia, is independently associated with elevated cFGF23 levels in the general population and with elevated cFGF23 and iFGF23 levels in patients with chronic kidney disease (CKD), in whom FGF23 cleavage may be impaired.

Considerations in the repurposing of mefloquine for prevention and treatment of osteoporosis
I read with interest the recent paper by Pacheco-Costa and colleagues [1], which demonstrates that the antimalarial drug mefloquine can affect bone formation in a mouse model. The authors note that mefloquine may be able to at least partially reverse the deleterious consequences of aging in bone, suggesting the potential repurposing of this drug for prevention and treatment of osteoporosis.

Higher sympathetic activity as a risk factor for skeletal deterioration in pheochromocytoma
Despite the potential biological importance of sympathetic activity in human bone metabolism, its effects on bone microarchitecture, a key determinant of bone quality, has not been thoroughly studied. In the present study, we investigated the lumbar spine trabecular bone score (TBS) as an indicator of skeletal deterioration in pheochromocytoma. Among 620 consecutive patients with newly diagnosed adrenal incidentaloma, 29 with histologically confirmed pheochromocytoma (a catecholamine-secreting neuroendocrine tumor) and 266 with nonfunctional adrenal incidentaloma were defined as cases and controls, respectively.
