ABSTRACT
Objectives@#The objective of this study is to assess outcomes and patient's mortality of Police General Hospital's fracture liaison service (PGH's FLS) during Coronavirus disease 2019 (COVID-19) outbreak comparing to the former period. @*Methods@#Retrospective cohort study was performed in patients aged 50 or older who were admitted with fragility hip fracture in Police General Hospital, Bangkok, between January 1, 2018 to December 31, 2019 (before pandemic) comparing to January 1, 2020 to December 31, 2021 (pandemic) using the electronic database. The outcomes were mortality and other outcomes in one-year follow up. @*Results@#A total of 139 fragility hip fractures were recorded in 2018–2019 (before pandemic) compared with 125 in 2020–2021 (pandemic). The 30-day mortality in hip fracture numerically increased from 0% to 2.4% during the pandemic. One-year mortality was significantly escalated from 2 cases (1.4%) to 5 cases (4%) (P = 0.033). However, the cause of mortality was not related with COVID-19 infection. We also found a significantly shorter time to surgery but longer wait time for bone mineral density (BMD) testing and initiation of osteoporosis medication in pandemic period. @*Conclusions@#The results of this study in COVID-19 pandemic period, 1-year mortality rate was significantly higher but they were not related with COVID-19 infection. We also found longer time to initial BMD testing and anti-osteoporotic medication and more loss of follow up, causing lower anti-osteoporotic medication taking. In contrast, the time to surgery became shorter during the pandemic.
ABSTRACT
Objectives@#To evaluate the role of trabecular bone score (TBS), in addition to bone mineral density (BMD), and to aid decision making to initiate anti-osteoporotic treatment in postmenopausal women with osteopenia. @*Methods@#TBS was assessed in a cohort of Thai postmenopausal women with BMD of femoral neck (FN), total hip (TH), and lumbar spine (LS) performed at the Police General Hospital, Bangkok, Thailand from July 2019 to October 2020. We retrospectively reviewed hospital database for underlying diseases, medication, and fractures, including relevant imaging and vertebral fracture assessment (VFA). Patients with previous osteoporosis treatment, skeletal malignancy, high-energy trauma, and uninterpretable BMD were excluded. @*Results@#In total there were 407 postmenopausal women, including 115 with osteoporotic fractures. The mean TBS of the cohort was 1.264 ± 0.005. The proportion of osteoporotic subjects ranged from 9.1% by TH BMD to 27.0% by lowest BMD. In fractured patients, 21.7%e54.8% were found to have osteoporosis while osteopenia was found in 37.4%e43.5%. Among subjects with osteopenia and degraded TBS, fractures ranged from 21.7 to 50.9%. Addition of osteopenic subjects with degraded microarchitecture yielded a significantly higher number of subjects eligible for treatment with 3.25-fold increase in non-fractured participants, and 7 to 11 additional osteopenic patients should be treated to detect 1 fracture. @*Conclusions@#Addition of TBS helped capturing osteopenic women with high risk of fracture. Decision to treat osteopenic women with degraded TBS increased the number of patients receiving treatment. We recommend evaluating TBS in osteopenic women without fractures to aid therapeutic decision on treatment initiation.
ABSTRACT
Objectives@#To compare the efficacy of cholecalciferol and ergocalciferol in raising 25-hydroxyvitamin D (25(OH)D) level in Thai female healthcare workers. @*Methods@#A randomized control trial was conducted in healthy female healthcare workers. Randomization allocated the participants into vitamin D2 group (N = 43), receiving ergocalciferol 20,000 IU weekly and vitamin D3 group (N = 40), receiving cholecalciferol 1000 IU daily for 12 months. Venous blood sample was collected at baseline, 6 and 12 months for serum 25(OH)D, parathyroid hormone and calcium. Compliance was also assessed. @*Results@#The mean age of the participants was 50.6 ± 9.9 and 50.9 ± 8.4 years in vitamin D2 and D3 groups (P = 0.884). The mean 25(OH)D levels were 16.91 ± 6.07 ng/mL and 17.62 ± 4.39 ng/mL (P = 0.547), respectively. Both groups had significant improvement in 25(OH)D level at 6 months (from 16.91 ± 6.07 to 21.67 ± 5.11 ng/mL and 17.62 ± 4.39 to 26.03 ± 6.59 ng/mL in vitamin D2 and D3 group). Improvement was significantly greater with cholecalciferol (P = 0.018). The level plateaued afterwards in both groups. Only cholecalciferol could increase 25(OH)D in participants without vitamin D deficiency (6.88 ± 4.20 ng/mL increment). Compliance was significantly better in vitamin D2 group (P = 0.025). @*Conclusions@#Daily cholecalciferol supplementation resulted in a larger increase in serum 25(OH)D level during the first 6 months comparing to weekly ergocalciferol. While vitamin D3 could increase serum 25(OH)D level in all participants, vitamin D2 could not do so in participants without vitamin D deficiency.
ABSTRACT
Objectives@#To compare the trabecular bone score (TBS) between Thai postmenopausal women with and without major osteoporotic fracture, and to determine whether TBS is associated with fracture risk. @*Methods@#All postmenopausal women sent for dual-energy X-ray absorptiometry (DXA) at the Police General Hospital were retrospectively recruited. The hospital’s online database and radiographs were reviewed to collect information on underlying disease, medication, previous fractures, bone mineral density, and trabecular bone score. Patients with anti-osteoporotic medication use, skeletal malignancy, fracture from high-energy trauma, and uninterpretable DXA images were excluded. @*Results@#A total of 407 Thai postmenopausal women were enrolled. They were divided into 292 women without fractures and 115 women with major osteoporotic fractures. The fracture group was older (73.36 ± 9.95 vs. 66.00 ± 8.58, P < 0.001) and had lower serum 25-hydroxyvitamin D levels (23.28 ± 9.09 vs. 26.44 ± 9.20, P = 0.023). The mean TBS was lower in the fracture group, compared to the non-fracture group (1.244 ± 0.101 vs. 1.272 ± 0.099, P = 0.011). The subgroup analysis resulted in noticeably lower TBS in spine fracture, but not other fracture sites. The odds ratio of fracture was 1.355 (P = 0.013) for a decrease in one standard deviation of TBS. @*Conclusions@#TBS was significantly lower in postmenopausal women having fractures with an odd ratio of 1.355 (P = 0.013) per SD decrease in TBS. Categorizing by fracture sites, TBS was only found to be noticeably lower in the lumbar spine despite similar lumbar spine bone mineral density.
ABSTRACT
Objectives@#To compare bone mineral density (BMD) in Thai postmenopausal women with and without distal radius fracture, and to investigate the role of vertebral fracture assessment (VFA) in diagnosing osteoporosis after distal radius fracture. @*Methods@#A cross-sectional study was conducted in Thai postmenopausal women with and without distal radius fracture. BMDs of the femoral neck (FN), total hip (TH), lumbar spine (LS), and VFA were obtained within 2 weeks of injury. BMD were compared between groups. Participants were classified into osteoporosis, osteopenia or normal using BMD alone, and BMD plus VFA, where a mere presence of vertebral compression fracture indicated osteoporosis. @*Results@#Fifty postmenopausal women with distal radius fractures and 111 non-fracture postmenopausal women participated. The mean BMD was significantly lower at all sites in the fracture group (FN BMD 0.590 ± 0.075 vs 0.671 ± 0.090, p = 0.007; TH BMD 0.742 ± 0.103 vs 0.828 ± 0.116, P = 0.009; LS BMD 0.799 ± 0.107 vs 0.890 ± 0.111, P = 0.009 in the fracture vs non-fracture group respectively). VFA increased the prevalence of osteoporosis from 16 (32%) to 23 (46%) in the fracture group, and 7 (6.31%) to 17 (16.22%) in the non-fracture group, with a number needed to treat 9. @*Conclusions@#Postmenopausal women with distal radius fractures had lower BMD. Incorporating VFA into diagnosis of osteoporosis increased the prevalence of osteoporosis in both fracture and non-fracture groups. Postmenopausal women aged 50 years or older with distal radius fracture are a good target for the investigation of osteoporosis.
ABSTRACT
Objectives@#Ankle fractures are common in the elderly. However, their association with osteoporosis remains controversial. This systematic review aims to determine the relationship between ankle fracture and bone mineral density (BMD), and to investigate the risk of subsequent fractures after ankle fracture. @*Methods@#MEDLINE and Scopus publications were searched from inception to March and April 2019, respectively. Articles were selected by 2 independent reviewers for cross-sectional, cohort, or casecontrol studies comparing BMD or subsequent fracture risk in low-energy ankle fractures patients with that of the normal population. Data extraction was performed by 2 investigators. Discrepancies were resolved with the third reviewer. Quality assessment was conducted using the modified NewcastleOttawa Scale. @*Results@#Overall, 19 articles were included. The quality assessment showed a generally low-to-moderate risk of bias among studies, mainly due to potential confounders and inadequate follow-up. Of 13 studies exploring BMD in ankle fractured-patients, lower central and peripheral BMD was found in 3 and 2 studies, respectively. The risk of subsequent fracture was examined in 11 studies with relative risks ranging from 0.7 to 4.59. An increased risk of any subsequent fractures in women, both genders, and men was found in 5, 2, and 1 articles, respectively. @*Conclusions@#Despite the lack of clear association with BMD, the contribution of ankle fracture to increased subsequent fracture risk and its associated microarchitectural changes cannot be overlooked.Moreover, its potential role as an early predictor of future fracture may promote secondary prevention.Further studies with longer follow-up and stricter confounder control are recommended.
