The adjusted incidence rate of hip fracture in Thailand has increased more than 31% from 1997 to 2006. Mortality and morbidity after hip fracture are also high. One year mortality after a hip fracture has increased from 18% in 1999 to 21% in 2007. The Thai Osteoporosis Foundation (TOPF) developed the first Clinical Practice Guideline (CPG) in 2002 and keeps updating the CPG since then. This latest version of the CPG is our attempt to provide comprehensive positional statement on the diagnosis, prevention and treatment of osteoporosis in Thailand. The study group who revised this position statement contains experts from the TOPF, Four Royal Colleges of Thailand, includes the Orthopaedic Surgeons, Gynecologists and Obstetricians, Physiatrists, Radiologists and 2 Associations of Endocrinologists and Rheumatologists which have involved in the management of patients with osteoporosis.

T2DM (Type 2 Diabetes Mellitus) patients with vertebral fractures have a higher mortality rate than non-DM (nondiabetic patients). However, the prevalence of vertebral fractures in the Asian diabetic population is not well established. Moreover, despite an apparent increase in fracture risk in patients with diabetes, Asian countries have provided contradictory data demonstrating that bone mineral density (BMD) varies significantly in T2DM patients. The aim of this study was to examine and compare the prevalence of vertebral fractures and osteoporosis, as well as BMD and the FRAX score, between individuals with and without T2DM and assess the association of these factors with vertebral fractures. Postmenopausal Thai women attending diabetic and health check-up clinics were recruited. BMD at the lumbar spine, total hip, and femoral neck was measured via dual-energy X-ray absorptiometry. A morphometric vertebral fracture (VF) was defined by a lateral thoracolumbar (T-L) X-ray radiograph. The Fracture Risk Assessment Tool (FRAX) was used to calculate the 10-year probabilities of hip and major osteoporotic fracture (MOF), which were calculated on the basis of the Thai FRAX model. A total of 435 participants were recruited, including 145 postmenopausal women with T2DM and 290 non-DM individuals. T2DM patients had a significantly greater BMI (p = 0.006) and BMD at the femoral neck (p = 0.024) and total hip (p = 0.017), but there was no significant difference in the FRAX score, including the 10-year probability of hip fracture or MOF, either with or without BMD, between individuals with and without T2DM. The prevalence of osteoporosis in non-DM women was significantly higher at the femoral neck (OR = 0.56, 95% CI: 0.34 to 0.93, p = 0.029) but comparable at the lumbar spine. Individuals with T2DM had a significantly higher rate of vertebral fractures, particularly those involving two or more levels, than those without T2DM. Diabetes was significantly associated with [Formula: see text]2 VF (OR = 3.83, 95% CI: 1.77 to 8.28, p = 0.001), and the association remained unchanged after controlling for other clinical factors (adjusted OR = 3.72, 95% CI 1.70-8.15; p = 0.001). Our study demonstrated a greater prevalence of multiple ([Formula: see text] two levels) VFs in women with T2DM than in non-DM controls., (© 2024. The Author(s).)

The outcome of this study was to identify 9-year survivors of intertrochanteric fracture at each stage of chronic kidney disease (CKD) and to investigate the risk factors associated with mortality following surgery with proximal femoral nail anti-rotation (PFNA). 443 elderly intertrochanteric fractures underwent PFNA fixation were recruited. Mortality rate was identified until 9 years. We compared the survival time of hip fracture in each stage of CKD. A regression analysis was used to determine the association between risk factors and one-year mortality. The overall median survival time was 7.1 years. The Kaplan-Meier curve was significantly different in each CKD stage especially in CKD5. In addition, the incidence rate of mortality was highest in CKD 5 (17.4%) and the median survival time in CKD 5 was 3.3 years. The multivariate analysis demonstrated that heart disease, operative time > 60 min, presence of pulmonary embolism, and poor to fair Harris hip score were significantly increased mortality. CKD stage 5 is associated with the highest mortality rate and the shortest median time of survival during the 9-year follow up. Patients who have high risk should focus on long-term care planning, including the counseling for their healthcare providers and families., (© 2024. The Author(s).)

Background: Data on reference values for lean mass (LM) and fat mass (FM) in the Southeast Asian populations are currently lacking. Therefore, we aimed to estimate the normative values and generate anthropometric prediction models for LM and FM in the Thai population. Methods: Consecutive community-dwelling individuals aged 20-90 years were recruited from Srinagarind Hospital, Khon Kaen, Thailand, between 2010 and 2015. LM and FM were measured using dual energy X-ray absorptiometry. Age and sex stratified percentile of LM and FM were presented. Anthropometric prediction models for LM and FM were developed by using linear regression to generate competing models. Results: A total of 832 individuals (334 males and 498 females) were included in the study. The mean ± SD age, LM, and FM were 50.0 ± 16.2 years, 38.9 ± 8.0 kg, and 15.5 ± 7.7 kg, respectively. LM decreased with age from 49.4 kg in 20-29 years group to 42.3 kg in ≥70 years group in male and 34.6 kg in 30-39 years group to 30.8 kg in ≥70 years group in females. FM has an inverse U-shaped association with age, which peaked at 11.9 kg in 60-69 years group in males and 20.7 kg in 50-59 years group in females. Among the various anthropometric models, the models incorporating age, sex, weight, and height were considered the best fit for predicting both LM and FM. Conclusion: In the Thai population, peak LM was reached during early adulthood and decline with age, whereas FM showed an inverse U-shaped association with age. The prediction models incorporating age, sex, weight, and height were proposed as practical tools for assessing LM and FM in clinical practice.

The current study aimed to investigate the prevalence trends of osteoporosis from 2003 to 2022 using data from the largest tertiary care referral center hospital in Northeastern Thailand. We reviewed 36,306 bone mineral density measurements of community-dwelling individuals aged > 45 years from the medical record database of Srinagarind Hospital, Khon Kaen, Thailand, between 2003 and 2022. We observed a significant increase in the crude prevalence of osteoporosis from 2003 to 2022. Meanwhile, the age-standardized prevalence increased more gradually., Purpose: To investigate the prevalence trends of osteoporosis from 2003 to 2022 using data from the largest tertiary care referral center in Northeastern Thailand., Methods: Bone mineral density (BMD) measurements of community-dwelling individuals aged > 45 years were reviewed from the medical record database of Srinagarind Hospital, Khon Kaen, Thailand, between 2003 and 2022. Osteoporosis was defined by a T-score of ≤  - 2.5. For each year, crude and age-standardized prevalence rates for osteoporosis stratified by site of measurement were calculated. Trend analysis was performed using the joinpoint regression method., Results: A total of 36,306 BMD measurements were identified between 2003 and 2022. The crude prevalence of femoral neck (FN) osteoporosis increased from 2.4% to 9.2% in men and from 2.5% to 11.2% in women, while the age-standardized prevalence increased less, from 2.6% to 8.3% in men, and slightly decreased from 8.7% to 7.6% in women. Trend analysis revealed increased crude and age-standardized prevalence rates of FN osteoporosis in men, with an annual percent change (APC) of 4.0 (95%CI: - 4.1 to 14.7) and 2.3 (95%CI: - 4.9 to 10.0), respectively. In women, the crude prevalence increased significantly from 2003 to 2011 (APC: 20.8, 95%CI: 5.8-249.3) and plateaued from 2011 to 2022 (APC: 0.8, 95%CI: - 30.3 to 5.9). The age-standardized prevalence was relatively unchanged (APC: 0.1, 95%CI: - 4.2 to 5.4)., Conclusion: We observed a significant increase in the crude prevalence of osteoporosis from 2003 to 2022 among individuals receiving BMD measurements in a tertiary care referral center in Northeastern Thailand. Meanwhile, the age-standardized prevalence increased more gradually., (© 2024. International Osteoporosis Foundation and Bone Health and Osteoporosis Foundation.)

Obesity is a global health threat affecting people of all ages, especially young adults. Early diagnosis of obesity allows for effective treatments and the prevention of its consequences. This study aimed to determine the prevalence of obesity in Thai young adults, evaluate the extent to which BMI values indicate excess adiposity, and identify the most appropriate BMI diagnostic cut-point based on body fat percentage. The study included 186 young adults aged 20 to 35 years. The diagnosis of obesity using body mass index (BMI) was compared with dual-energy X-ray absorptiometry-derived body fat percentage, considered the gold standard. The appropriate BMI cut-point was established using ROC curve analysis and the Youden index. Obesity was more common in women and in urban areas. BMI and body fat were significantly correlated; however, there was a high rate of false-negative obesity diagnosis based on the conventional BMI cut-off, a condition known as normal weight obesity (NWO). The newly proposed BMI cut-off points that best correlated with body fat and corrected false negatives were 22.1 kg/m 2 for men and 22.5 kg/m 2 for women. These new BMI cut-points should be applied together with clinical evaluations for obesity assessment in this particularly high-risk group.

Background: Bone mineral density (BMD) might not be a sensitive tool for predicting osteoporotic fracture risk among patients with rheumatoid arthritis (RA), especially when receiving glucocorticoids. Trabecular bone score (TBS), which has emerged as a new assessment technique representing bone microarchitecture and strength, may be considered an alternative approach., Materials and Methods: In this cross-sectional analytical study, postmenopausal RA patients receiving glucocorticoids were identified from the postmenopause BMD database. The database included clinical data of postmenopausal outpatients who had at least one BMD measurement between January 2014 and December 2017. TBS was calculated from lumbar spine BMD with the microarchitecture assessment software. The presence of osteoporotic fractures, either vertebral or non-vertebral, was identified at the time of BMD measurement., Results: A total of 64 postmenopausal RA patients receiving glucocorticoids were included. The TBS values were inversely associated with osteoporotic fractures, with a TBS cut-off of less than 1.24, showing the best accuracy with a sensitivity of 79% and a specificity of 84% in discriminating fractures. This newly proposed TBS threshold combined with a BMD T-score of -2.5 or less demonstrated a greater area under receiver operating characteristic curve in identifying patients with osteoporotic fractures than the BMD threshold alone ( p value = 0.003)., Conclusion: The reduction in TBS was associated with an osteoporotic fracture in postmenopausal RA patients receiving glucocorticoids. Combining TBS and BMD in these patients incrementally improves fracture risk discrimination and may serve as a supplementary tool in identifying patients at greatest risk of osteoporotic fracture., Competing Interests: The authors report no conflicts of interest in this work., (© 2024 Ruangnopparut et al.)

Patients with transfusion-dependent thalassemia (TDT) have an increased risk of osteoporosis and fractures. They also have several potential factors associated with sarcopenia. There has been currently no study on sarcopenia and its association with falls and fractures in TDT. This study aims to determine the prevalence of and factors associated with osteoporosis, fragility fractures, and sarcopenia in adults with TDT. A cross-sectional study was conducted at the hematologic clinic at King Chulalongkorn Memorial Hospital, Bangkok, Thailand. Clinical data and laboratory testing were collected. Bone mineral density and morphometric vertebral fracture were assessed. Sarcopenia was defined using the 2014 and 2019 Asian Working Group for Sarcopenia (AWGS) criteria. We included 112 TDT patients aged 35.1 ± 12.5 years. The prevalence of osteoporosis was 38.4%. Fragility fractures were found in 20.5% of patients. Lower BMI (OR 0.29; 95% CI 0.12-0.72, P = 0.007) and hypogonadal state (OR 3.72; 95% CI 1.09-12.74, P = 0.036) were independently associated with osteoporosis. According to the 2014 AWGS criteria, the prevalence of overall sarcopenia and severe sarcopenia was 44.6% and 13.4%, respectively. Severe sarcopenia was strongly associated with fragility fractures (OR 4.59, 95% CI 1.21-17.46, P = 0.025). In conclusion, osteoporosis, fragility fractures, and sarcopenia were prevalent in adults with TDT. Severe sarcopenia was associated with fragility fractures. Early osteoporosis and sarcopenia screening and prevention may reduce fracture risk and its complications in these patients., (© 2023. Springer Nature Limited.)

Axial spondyloarthritis (axSpA) increases the risk of osteoporosis and vertebral fractures. Bone mineral density (BMD) measured by dual X-ray absorptiometry (DXA) has limitations in axSpA patients. Trabecular bone score (TBS) indirectly assesses bone microarchitecture and can be used to predict fracture risk. However, few studies have investigated the role of TBS in axSpA patients. The objective of this study were to compare TBS between axSpA patients and 1:1 sex- and age-matched healthy volunteers and determine factors associated with low TBS in axSpA patients. A cross-sectional study was conducted in two tertiary-care hospitals. A total of 137 axSpA patients and healthy volunteers were enrolled. Demographics, disease characteristics, and risk factors for osteoporosis were recorded. TBS, BMD at the lumbar spine, hip, and vertebral fractures were assessed by DXA. Low TBS was defined as a TBS value < 1.230. Factors associated with low TBS were examined by logistic regression. Most patients were male (75.9%) and tested positive for HLA-B27 (88.3%). The mean (SD) age was 42.8 (12.0) years. The mean (SD) of TBS in the axSpA patients was lower than those in the healthy volunteers [1.402 (0.107) vs 1.440 (0.086), respectively; p = 0.002]. The mean (SD) of lumbar BMD in the axSpA patients was higher than in healthy volunteers [1.186 (0.212) vs 1.087 (0.124), p < 0.001], whereas the mean (SD) of femoral neck BMD in the axSpA group was lower than that in the healthy volunteers [0.867 (0.136) vs 0.904 (0.155), p = 0.038]. Disease severity as indicated by sacroiliac joint fusion and a high ASDAS score were associated with low TBS with the odds ratios (95% confidence interval) of 11.8 (1.2-115.4) and 5.2 (1.6-16.9), respectively. In conclusion, axSpA patients had a higher prevalence of low TBS than healthy volunteers. Sacroiliac joint fusion and a high ASDAS score were associated with low TBS., (© 2023.

Background: Ineffective erythropoiesis (IE) is a significant risk factor for osteoporosis in individuals with thalassemia. Growth differentiation factor-15 (GDF15), a biomarker of IE, was found to be elevated in thalassemia patients. This study aimed to examine the association between GDF15 levels and osteoporosis in patients with thalassemia., Methods: A cross-sectional study was conducted in 130 adult patients with thalassemia in Thailand. Bone mineral density (BMD) at the lumbar spine was evaluated by dual-energy X-ray absorptiometry (DXA), and with a Z-score of less than -2.0 SD was defined as osteoporosis. GDF-15 was measured using the enzyme-linked immunosorbent assay (ELISA). Logistic regression analysis was used to examine the associated factors with the development of osteoporosis. Receiver operator characteristic (ROC) curve analysis was used to estimate the threshold of GDF15 in predicting osteoporosis., Results: Osteoporosis was detected in 55.4% (72/130) of the patients. Advanced age and high GDF15 levels were positively associated with osteoporosis, while an increased hemoglobin level was negatively associated with osteoporosis in patients with thalassemia. In this study, the GDF15 level's ROC demonstrated a good performance in predicting osteoporosis (AUC=0.77)., Conclusions: The prevalence of osteoporosis is high among adult thalassemia patients. Age and high GDF15 levels were significantly associated with osteoporosis in this study. A higher hemoglobin level is associated with a lower risk of osteoporosis. This study suggest that GDF15 could be used as a predictive biomarker for osteoporosis in patients with thalassemia. Adequate red blood cell transfusions and suppression of GDF15 function may be beneficial in preventing osteoporosis., Competing Interests: Declaration of Competing Interest The authors report no conflicts of interest., (Copyright © 2023 Southern Society for Clinical Investigation.

Objective: To investigate bone fragility in patients with hereditary connective tissue disorders (HCTD), including Ehlers-Danlos syndrome (EDS), Marfan's syndrome (MFS) and Loeys-Dietz syndrome (LDS)., Methods: From inception to June 2022, potentially eligible studies were identified in the Medline and EMBASE databases using search strategy that included terms for "HCTD", "Fracture" and "Osteoporosis". Eligible studies must consist of a group of patients with HCTD and report prevalence/incidence of fracture/osteoporosis in their participants, with or without comparison with healthy individuals. Point estimates with standard errors were obtained from each study and combined using the generic inverse variance method., Results: Among the 4206 articles identified, 19 studies were included. The pooled prevalence of fracture in EDS, MFS, and LDS were 44% (95% confidence interval [CI], 25% to 65%, I 2 88%), 17% (95% CI, 11% to 26%, I 2 68%), 69% (95% CI, 47% to 85%, I 2 83%), respectively. The pooled prevalence of osteoporosis in EDS was 17% (95% CI, 8% to 34%, I 2 96%). EDS was associated with fracture [pooled odds ratio {OR} 4.90 (95% CI, 1.49 - 16.08, I 2 86%)], but not osteoporosis [pooled OR 1.34 (95% CI, 0.28 - 6.36, I 2 87%). One study reported a 5% (95% CI, 3% to 8%) prevalence of osteoporosis in MFS, which was associated with fracture [incidence rate ratio 1.35 (95% CI, 1.18 - 1.55)] and osteoporosis [subhazard ratio 3.97 (95% CI, 2.53 - 6.25)]., Conclusion: EDS was associated with fracture, which could be independent of osteoporosis status. MFS had a milder degree of increased risk of fracture and osteoporosis. Despite no data from cohort studies, there was a significantly higher rate of fracture in LDS., Competing Interests: Disclosure The authors have no multiplicity of interest to disclose., (Copyright © 2023 AACE.

Osteoporosis is a major public health issue in Thailand, which increased morbidity, mortality, and health-care utilization. The objective of this review is to provide current perspectives on epidemiology, evaluation and management of osteoporosis in Thailand. According to epidemiologic data, the prevalence of osteoporosis and the incidence of hip fracture were comparable to the rest of the world. However, among Thai postmenopausal women, the prevalence of asymptomatic vertebral fracture was disproportionately high. In addition to established risk factors, conditions that may affect the risk of osteoporosis in the Thai population include certain genetic variants, thalassemia, vitamin D deficiency, and low dietary calcium intake, which requires further investigations to draw conclusions. In 2021, the Thai Osteoporosis Foundation released a new Clinical Practice Guideline that provides up-to-date evidence-based recommendations for evaluation and management of osteoporosis. Nonetheless, more research is required to provide local evidence in a variety of areas to guide management of osteoporosis in Thailand. These include epidemiology of distal radial fracture, the optimal intervention threshold of the Thai-specific Fracture Risk Assessment Tool model, screening for asymptomatic vertebral fracture, and the economic evaluation of osteoporosis management options, including fracture liaison service., Competing Interests: The authors declare no competing interests., (© 2023 The Korean Society of Osteoporosis.

Background: Obesity is known to be a protective factor against osteoporosis. However, recent studies have shown that excessive adiposity may be detrimental for bone health., Objective: To determine the association of lean mass (LM) and fat mass (FM) with bone mineral density (BMD) in Thais., Methods: Bone density studies of consecutive patients of Srinagarind Hospital, Khon Kaen, Thailand between 2010 and 2015 were reviewed. LM, FM, lumbar spine (LS) and femoral neck (FN) BMD were measured. Lean mass index (LMI) and fat mass index (FMI) were calculated [LMI=LM (kg)/height (m) 2 , FMI=FM (kg)/height (m) 2 ] and analyzed to determine the association with LS and FN BMD using multiple regression analysis. This study was approved by the institutional ethical committee (HE42116)., Results: A total of 831 participants were included. The mean ± SD age was 50.0 ± 16.3 years. In men, LMI (per 1 kg/m 2 increase) was positively correlated with FN BMD (g/cm 2 , β 0.033) and LS BMD (g/cm 2 , β 0.031), after adjusting for age, height and FMI. Whereas FMI (per 1 kg/m 2 increase) was negatively correlated with FN BMD (g/cm 2 , β -0.015) but not with LS BMD (g/cm 2 , β 0.005) after adjusting for age, height and LMI. In women, both LMI and FMI were positively correlated with LS BMD (g/cm 2 , LMI: β 0.012; FMI: β 0.016) and FN BMD (g/cm 2 , LMI: β 0.034; FMI: β 0.007) with age, height, LMI and FMI included in the model., Conclusion: Our findings indicate that FM has a sex-specific influence on BMD in Thais., Competing Interests: CA has participated on advisory boards for Abbott Nutrition, Allergan, Inc., Altimmune, Inc., Bariatrix Nutrition, Cowen and Company, LLC, Curavit Clinical Research, EnteroMedics, Gelesis, Srl., Janssen, Jazz Pharmaceuticals, Inc., L-Nutra, Inc., NeuroBo Pharmaceuticals, Inc., Novo Nordisk, Inc., Nutrisystem, Pain Script Corporation, Real Appeal, Riverview School, Rhythm Pharmaceuticals, Roman Health Ventures, Inc., SetPoint Health, Scientific Intake Ltd.

Purpose: To determine the proportion of postmenopausal Thai women who would be classified as having high risk of fracture and eligible for anti-osteoporosis therapy according to the National Osteoporosis Foundation (NOF) criteria., Methods: Postmenopausal Thai women aged 40-90 years who had been screened for osteoporosis during 2014-2019 were recruited. Demographic data and osteoporosis risk factors were collected based on the Fracture Risk Assessment Tool (FRAX) questionnaire. Bone mineral density (BMD) at the femoral neck and lumbar spine measured using dual energy X-ray absorptiometry. Ten-year probabilities of hip and major osteoporotic fracture (MOF) were calculated based on the Thai FRAX model with BMD. The study's protocol was approved by the Institutional Ethical Committee (HE581241)., Results: A total of 3,280 postmenopausal women were included. The mean ± SD age was 63.6 ± 10.1 years. A total of 170 (5.2%) participants had a history of hip and/or vertebral fracture. After excluding these participants with fracture history, 699 (21.3%) had osteoporosis, 355 (10.8%) had osteopenia with high risk of fracture (FRAX 10-year probability of hip fracture ≥ 3% and/or MOF ≥ 20%), 1192 (36.3%) had osteopenia with low risk of fracture (FRAX 10-year probability of hip fracture < 3% and MOF < 20%) and 864 (26.3%) had normal BMD. Taken together, a total of 1,224 (37.3%) participants would be eligible for anti-osteoporosis therapy (prior fracture, osteoporosis or osteopenia with high risk of fracture)., Conclusion: The prevalence of Thai postmenopausal women who would be eligible for anti-osteoporosis therapy was 37.3%., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Chanidkul et al.

Introduction: Little is known about the normative values of trabecular bone score (TBS) in Thailand. We aimed to provide reference values of dual-energy x-ray absorptiometry (DXA)-derived lumbar spine TBS in Thai community-dwelling adults of varying ages., Methodology: Bone density studies of participants aged 20-90 years who underwent bone mineral density (BMD) testing at Srinagarind Hospital, Kohn Kaen, Thailand were reviewed. DXA studies were performed using a narrow fan-beam bone densitometer. Lumbar spine TBS for each of the L1-L4 vertebra was obtained using the iNsight software. Mean TBS (L1-L4 TBS) was calculated. This study was approved by the institutional research ethics committee (HE581241)., Results: A total of 1372 participants were included. The mean ± SD age was 57.25 ± 17.35 years and 799 (58.2%) were female. There were 476 (34.7%) and 243 (17.7%) participants with osteopenia (T-score -1.0 to -2.5) and osteoporosis (T-score ≤-2.5) of the lumbar spine. Age and sex stratified analysis of L1-L4 TBS revealed peak TBS among females aged 30-49 years (mean ± SD: 1.42 ± 0.08) and males aged 30-59 years (mean ± SD: 1.42 ± 0.09). The rate of L1-L4 TBS reduction from ages 30 to 90 year is 13.4% (0.27%/year) for females and 5.6% (0.11%/year) for males., Conclusion: This is the first study reporting a normative database for DXA derived TBS in Thai community-dwelling population. We found that TBS decreased with age at the rate of approximately 0.27%/year for females and 0.11%/year for males., Competing Interests: Declaration of Competing Interest Chatlert Pongchaiyakul, Daris Theerakulpisut, Nipith Charoenngam, Thanitsara Rittiphairoj, Dueanchonnee Sribenjalak declare no conflicts of interest, (Copyright © 2022 The International Society for Clinical Densitometry.

Typically, intramedullary and extramedullary devices are used to treat elderly with intertrochanteric fractures. The majority of previous research has focused on the association between surgical factors and mechanical failure after internal fixation. There is, however, limited evidence to demonstrate the association between functional outcomes after proximal femoral nail anti-rotation (PFNA) fixation and the non-surgical factors such as patient's comorbidities. The aim of this study is to determine the predictive factors associated with excellent outcome, as well as to develop an integrated scoring system to predict the outcome after PFNA fixation in elderly patients with an intertrochanteric fracture. A retrospective study was conducted between January 2012 and December 2018. Elderly patients with low-energy intertrochanteric fractures who underwent PFNA fixation and at least a year of follow-up were recruited. Demographics, comorbidities, cognitive status, time to operation, and surgical parameters of the patients were all identified. Excellent and non-excellent outcomes were assessed by Harris Hip Score (HHS) after a one-year follow up. Regression analysis was used to determine the predictors for an excellent functional outcome. A new integrated scoring system (ISSI; Integrate Scoring System in elderly patients with Intertrochanteric fracture) was developed and validated. 450 elderly patients were randomly divided into two cohorts: a development (N = 225) and validation cohorts (N = 225). In this study, age < 85 years, normal weight/overweight, Charlson comorbidity index (CCI) < 6, no cognitive impairment, a modified AO/OTA 31A1.3, time to operation < 6 days, and Tip Apex Distance between 20 and 30 mm were significantly associated with an excellent outcome after PFNA fixation. The range of ISSI score was between 0 to 16 and the cut-off score of 13 was found to have the highest discriminatory power to determine the excellent functional outcome where the area of ROC was 0.85. In regards to the validation cohort, the sensitivity and specificity of ISSI score was 69% and 87%, respectively, and the AUC was 0.81. The ISSI score is effortless and practical for orthopedic surgeons for predicting an outcome after PFNA fixation in elderly patients with an intertrochanteric fracture., (© 2022. The Author(s).)

Patients with systemic sclerosis (SSc) have some potential factors associated with an increased risk of sarcopenia. There has been currently no study to examine such associations in SSc patients. We aimed to determine the prevalence of sarcopenia among SSc patients and examine its association with clinical manifestations and laboratory tests. A cross-sectional study was conducted in 180 adult SSc patients at the Scleroderma Clinic, Khon Kaen University, Thailand, between July 2019 and April 2020. Clinical data, laboratory tests for inflammatory markers, serology, hormone, body composition by dual-energy X-ray absorptiometry, handgrip strength, functional lower extremity strength, and usual gait speed were collected and measured. Sarcopenia was defined according to the criteria of the Asian Working Group for Sarcopenia. One hundred and eighty patients were recruited. Ninety-four cases (52.2%) were the diffuse cutaneous SSc subset. The respective mean age and duration of disease was 58.8 ± 9.4 and 6.2 ± 5.3 years. Sarcopenia was revealed in 41 SSc patients for a prevalence of 22.8% (95% CI 12.1-34.8), while the prevalence was higher in patients with the diffuse cutaneous SSc (dcSSc) compared to the limited cutaneous SSc. BMI at the onset of SSc and C-reactive protein > 5 mg/dL were significantly associated with sarcopenia with a respective OR of 0.60 (95% CI 0.48-0.75) and 3.18 (1.06-9.54). Sarcopenia is common in patients with SSc, but the prevalence is more pronounced in the dcSSc. Inflammatory markers, particularly the CRP level, are strongly associated. BMI at the onset had a negative association with sarcopenia among SSc patients., (© 2022. The Author(s).)

This study was designed to determine a FRAX intervention threshold in postmenopausal Thais, based on a history of hip fracture. The optimal FRAX thresholds for hip fracture were 4.9% (without BMD) and 4% (with BMD), while the thresholds for major osteoporotic fracture were 9.8% (without BMD) and 8.9% (with BMD)., Introduction: Fracture Risk Assessment Tool (FRAX) has been widely used as an intervention threshold for initiating osteoporosis treatment. However, there is a lack of data to validate the threshold in Thai population., Methods: A cross-sectional study was conducted from January 2014 to February 2019. Postmenopausal women in the Northeast of Thailand whom has bone mineral density (BMD) measured using dual-energy X-ray absorptiometry (DXA) in the study period were recruited. Participants who had previously received anti-osteoporotic treatment were not eligible. FRAX score, both with and without BMD, was calculated using a Thai reference. Prevalent hip fracture was identified by reviewing the ICD-10 diagnosis from the hospital database during the study period. The receiver operating characteristic (ROC) curve and Youden index were used to determine the FRAX threshold in predicting hip fracture, based on the rationale that women with a prevalent hip fracture would be eligible for treatment., Results: A total of 2872 postmenopausal Thai women were recruited, with 45 sustained a recent hip fracture. In association with hip fracture, the optimal FRAX thresholds for hip fracture without and with BMD were 4.9% and 4%, respectively, with 71.1% sensitivity and 83.3% specificity, and 82.2% sensitivity and 78.6% specificity, while the optimal FRAX thresholds for major osteoporotic fracture (MOF) without and with BMD were 9.8% and 8.9%, respectively, with 75.6% sensitivity and 77.0% specificity, and 86.7% sensitivity and 70.9% specificity., Conclusion: An optimal intervention threshold based on FRAX of hip fracture and MOF in postmenopausal Thai women is slightly different from the standard recommendation, which confirmed the marked variations of thresholds across ethnicities. The proposed threshold should be considered as new cutoff for initiating osteoporosis treatment in postmenopausal Thais., (© 2022.

Introduction: The comparative effect of new-onset diabetes mellitus (DM) and hypertension (HT) on long-term mortality is a matter of debate., Materials and Methods: From 2007 to 2017, a 10-year longitudinal retrospective cohort study was conducted in Thailand's tertiary care setting. As baseline data, health check-up data from apparently healthy participants without underlying disease from 2007 were extracted. The vital status of all participants was determined in 2017, ten years after an initial examination. The impact of new-onset DM and HT at baseline on 10-year all-cause mortality was investigated using multivariable logistic regression analysis., Results: The prevalence of new-onset DM and HT was 6.4% and 28.8%, respectively, at baseline. Newly diagnosed diabetes increased the risk of all-cause mortality over 10 years (adjusted OR 4.77 and 95% CI 2.23-9.99). HT, on the other hand, did not increase the risk of death (adjusted OR 1.24 and 95% CI 0.65-2.35). Different HT and DM status combinations were compared to a nondiabetic, nonhypertensive reference. Individuals who were diabetic and hypertensive had a greater risk of death (adjusted OR 6.22 and 95% CI 2.22-17.00). Having DM without HT also increased the risk of death (adjusted OR 4.36 and 95% CI 1.35-12.87). However, having HT without DM did not result in a significant increase in 10-year mortality risk (adjusted OR 1.21 and 95% CI 0.57-2.56)., Conclusion: In an apparently healthy population, new-onset DM is more strongly associated with 10-year all-cause mortality than new-onset HT. Having both DM and HT was associated with a greater risk of death when compared to having DM or HT alone., Competing Interests: All authors have no competing interests to declare., (Copyright © 2021 Suranut Charoensri et al.)

Background: Fasting hypertriglyceridemia commonly associates with insulin resistance and is frequently prevalent in type 2 diabetes mellitus (DM). However, hypertriglyceridemia has not been investigated as an independent predictor of incidence of DM, especially in Thais., Methods: A 10-year hospital-based retrospective cohort study was conducted in a tertiary care setting in Thailand. Health check-up data in 2007 from healthy participants without underlying disease were extracted as baseline data. In 2017, 10 years following an initial examination, the diagnosis of DM and other laboratory data were identified. Hypertriglyceridemia was defined as fasting triglyceride level ≥ 150 mg/dL. A generalized additive model (GAM) was applied to demonstrate a relationship between fasting TG level and probability of incident DM in 10 years. An association between hypertriglyceridemia and 10-year incidence of DM was evaluated using univariable and multivariable logistic regression analysis., Results: A total of 1342 non-diabetic adults with complete both baseline and 10-year follow-up data were included in the analysis. The incidence of DM in the study period was 10.3%. Baseline fasting triglyceride level is significantly higher in participants with incidence of DM, with a median difference of 45 mg/dL ( P < 0.01). Univariable logistic regression showed that hypertriglyceridemia was associated with 10-year incidence of DM (odds ratio (OR) 3.03, 95% CI 2.12-4.35). After adjusting for potential confounders, hypertriglyceridemia remained significantly associated with incidence of DM (OR 2.33, 95% CI 1.61-3.39)., Conclusion: Fasting triglyceride level is an independent risk factor for the development of new-onset DM. Testing for hypertriglyceridemia in people without diabetes may be an alternative screening tool to identify populations at risk of developing future DM, as well as providing triglyceride as a new target for DM risk reduction., Competing Interests: The authors report no conflicts of interest in this work., (© 2021 Charoensri et al.)

Systemic sclerosis (SSc) is recognized as a chronic inflammatory disease and several SSc-associated factors may increase the risk of osteoporosis and its related fractures. To determine the prevalence and predictive factors of osteoporosis in Thai SSc, a cross-sectional study was designed in adult SSc patients at Scleroderma clinic, Khon Kaen University Hospital. The prevalence of osteoporosis with the 95% confidence interval (CI) were determined and the odds ratio (OR) with 95%CI were assessed the clinical association with osteoporosis. A total of 205 SSc patients were recruited with the female to male ratio of 2.7:1. The majority of cases were diffuse SSc subset (83.4%) with a disease duration < 5 years (62.9%). The overall prevalence of osteoporosis was 29.3% (95%CI 23.1-36.0). After an age adjusted analysis, the respective prevalence of osteoporosis at lumbar spine (LS) in women and men was 26.3% and 10%, while the prevalence of osteoporosis at the femoral neck (FN) in women and men was 11% and 2.1%. Low BMI (≤ 18.5 kg/m 2 ) and menopause were associated with osteoporosis at both the LS and FN. Using multivariate analysis, low BMI and menopause were associated with osteoporosis at LS (OR 7.78 and 5.32, respectively), while low BMI was also associated with osteoporosis at LS in pre-menopausal women. In conclusion, the prevalence of osteoporosis in Thai SSc was 29.3%. Osteoporosis at the LS is more common than FN in both men and women. Low BMI was associated with osteoporosis in overall SSc and pre-menopausal women, while only menopause was associated with osteoporosis at the FN.

We investigate the rate of concordance between treatment recommendations of osteoporosis with 10-year probability of hip fracture calculated using FRAX scores with and without BMD. We found that predictions were concordant in 83.8% of patients. However, older age, lower BMD, and FRAX without BMD around the intervention threshold were associated with discordant results. In the discordant group, FRAX with BMD suggested treatment in more participants with lower age, higher BMI, and lower BMD when compared with FRAX without BMD., Introduction: The Fracture Risk Assessment Tool (FRAX) is used to calculate the 10-year probability of fracture using important clinical factors, with bone mineral density (BMD) as an optional input variable. We aimed to determine the rate of concordance between treatment recommendations of osteoporosis with 10-year probability of hip fracture calculated using FRAX scores with and without BMD and to identify relevant clinical risk factors associated with discordance., Methods: This was a cross-sectional study conducted in patients between 40 and 90 years of age who were screened for osteoporosis by BMD measurement using dual energy X-ray absorptiometry (DXA) from 2010 to 2018 at a university hospital in Thailand. A FRAX questionnaire was administered to determine demographic data and osteoporotic risk factors. FRAX scores with and without BMD were calculated for each participant using the Thai reference, and patients were categorized into either the treatment or non-treatment group based on a cut-off of 3% 10-year probability of hip fracture. When FRAX scores with and without BMD results were consistent, they were considered concordant. Otherwise, they were deemed discordant. Clinical risk factors were compared between the concordant and discordant groups., Results: A total of 3545 participants were included in the study. The majority (83.8%) were in the concordant group. However, older age, lower BMD, and FRAX without BMD around the intervention threshold were significantly associated with discordant results. In the discordant group, FRAX with BMD suggested treatment in more participants with lower age, higher BMI, and lower BMD when compared with FRAX without BMD., Conclusion: FRAX scores with and without BMD yielded concordant predictions regarding the 10-year probability of hip fracture suggesting pharmacological treatment. However, this concordance declined in elderly and osteoporotic participants and in those with FRAX without BMD around intervention threshold. BMD data may be required in these populations in order to facilitate accurate risk assessment.

Background: Hungry bone syndrome (HBS) following parathyroidectomy is associated with severe hypocalcemia and increased morbidity. This study aims to determine the incidence and risk factors of post-parathyroidectomy HBS in dialysis patients with secondary hyperparathyroidism (SHPT)., Methods: A retrospective cohort study was conducted, and medical records of patients with SHPT requiring parathyroidectomy between January 2014 and January 2020 were reviewed. HBS was defined as the requirement of intravenous calcium administration due to hypocalcemia-related symptoms and/or reductions in serum calcium concentration (<8.4 mg/dL) within 72 h after parathyroidectomy., Results: A total of 130 dialysis patients were enrolled. The majority of patients (85.4%) received hemodialysis and the remaining patients (14.6%) received peritoneal dialysis. Ectopic parathyroid glands were identified in 6.6% of patients by preoperative parathyroid scintigraphy. Diffuse parathyroid hyperplasia was the most common histopathological characteristic of SHPT (90.8%). HBS occurred in 82.3% of patients following parathyroidectomy. Preoperative serum intact parathyroid hormone (iPTH) concentration was significantly correlated with serum calcium ( r = -0.48, p  < 0.01) and alkaline phosphatase (ALP) concentration ( r  = 0.71, p  < 0.01). Patients with HBS had significantly longer hospital stays than patients without (8 versus 3 days, p  < 0.01). Based on multiple logistic regression analysis, young age (≤45 years), high preoperative serum ALP (>420 IU/L) and iPTH (>1,000 pg/mL), and absence of preoperative hypercalcemia (>10.2 mg/dL) were significantly associated with HBS., Conclusions: Post-parathyroidectomy HBS is common in dialysis patients with SHPT. Young age, high preoperative serum ALP and iPTH, and low preoperative serum calcium concentrations were important risk factors for HBS.

Purpose: The long-term impact of changes in serum uric acid (SUA) concentration on the estimated glomerular filtration rate (eGFR) among the general population remains unclear. We investigated the longitudinal associations between changes in SUA and eGFR over 10 years in 1222 participants with baseline eGFR ≥60 mL/min/1.73 m 2 ., Methods: This was a 10-year retrospective cohort study conducted from 2007 to 2017. Rapid eGFR decline (defined as the highest quartile of change in eGFR between 2007 and 2017) and new-onset kidney disease (defined as an eGFR <60 mL/min/1.73 m 2 at a 10-year follow-up) were examined using multiple logistic regression analysis, adjusted for sex, age, body mass index, systolic blood pressure, SUA, fasting plasma glucose, serum total cholesterol, and triglyceride at baseline., Results: SUA was inversely correlated with eGFR, and the slopes of the SUA-eGFR regression lines were consistently steeper in females than males. A significant inverse correlation was also observed between 10-year changes in SUA and eGFR in both sexes. Multivariate analysis showed that every 1 mg/dL increase in SUA from baseline was associated with higher risk of rapid eGFR decline and new-onset kidney disease (OR 1.25; 95% CI 1.14-1.33 and OR 1.40; 95% CI 1.26-1.49, respectively). Furthermore, the subjects in the highest SUA quartile (>6.0 mg/dL) had a 2.45 times higher risk of rapid eGFR decline (95% CI 1.51-3.42) compared to those in the lowest SUA quartile (<3.9 mg/dL)., Conclusion: Elevated baseline SUA is an independent risk factor for rapid eGFR decline and new-onset kidney disease in the general population., Competing Interests: All authors listed on the title page report no conflicts of interest in this work., (© 2020 Kritmetapak et al.)

Objective: To determine the prevalence of and risk factors for morphometric vertebral fracture (VF) in apparently healthy postmenopausal women with osteopenia., Methods: This cross-sectional study included 490 postmenopausal Thai women with osteopenia. All had no known history of low-trauma fracture, no underlying diseases, or history of taking medications that affect bone metabolism. Morphometric VFs were assessed by thoracolumbar spine x-rays, using the Genant semiquantitative method, and interpreted independently by three radiologists., Results: Mean age of participants was 59.9 ± 7.8 years and mean body mass index was 24.3 ± 3.4 kg/m2. Morphometric VFs were present in 29% (142/490) of women (grade 1: 62.0%, grade 2: 19.3%, and grade 3: 18.7%). Of these, 4.9% were aged 50 years or less, 40.1% were aged 50-59 years, 38% were aged 60-69 years, and 16.9% were aged over 70 years. Age and the Fracture Risk Assessment Tool (FRAX) scores for hip and major osteoporotic fracture, with or without bone mineral density, were positively correlated with VF. No differences in fracture prevalence among those with various degrees of osteopenia. Applying the current guidelines for VF screening results in discoveries of less than a half of osteopenic women who have had morphometric VF., Conclusions: Almost one third of apparently healthy postmenopausal women with osteopenia had morphometric VF. Advancing age and greater FRAX scores were associated with higher prevalence of morphometric VF., Competing Interests: Financial disclosure/conflicts of interest: None reported., (Copyright © 2020 by The North American Menopause Society.)

Introduction: Thalassemia bone disease is one of the disease-related complications in patients with thalassemia. Prevalence of fractures and the role of a trabecular bone score (TBS) as a predictive factor for fractures were evaluated in patients with thalassemia., Methods: A cross-sectional study was conducted in patients with thalassemia aged ≥18 years at Srinagarind Hospital, Khon Kaen University, Thailand. A lateral thoracolumbar radiograph and bone mineral density (BMD) at the lumbar spine and hip, as well as the TBS measured by dual-energy X-ray absorptiometry (DXA), were evaluated in all patients., Results: Among 86 patients, 14 patients were found to have radiographic vertebral fracture yielding a prevalence of 16.3%. All patients who had fractures were β -thalassemia/Hb E. Combined low BMD and TBS at lumbar spines and a presence of endocrinopathies were significantly associated with vertebral fractures., Conclusions: The prevalence of vertebral fractures in patients with thalassemia was not uncommon. A combined low BMD and TBS and a presence of endocrinopathies were associated with vertebral fractures. These findings suggested that BMD testing and TBS measurement have a clinical implication as a screening tool for evaluating the risk of vertebral fractures in thalassemic patients, particularly in β -thalassemia/Hb E who have endocrinopathies., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 Nattiya Teawtrakul et al.)

Aims: This study assessed the cost-effectiveness of denosumab for treating postmenopausal women with osteoporosis (PMO) at high risk of fracture in Thailand. Materials and methods: A published Markov cohort cost-effectiveness model was populated with country-specific data as available and other published data as needed. The model used a societal perspective, lifetime horizon, efficacy data from network meta-analysis of trials, and included costs for direct medical and non-medical care, informal care, and osteoporosis treatments to compare denosumab to no pharmacologic treatment (calcium and vitamin D supplements only) and to oral weekly alendronate. The base case (high-risk population) included postmenopausal women with femoral neck T-score ≤-2.5, mean age 65 years at entry, and history of vertebral fracture. Results: High-risk women with osteoporosis using denosumab had the greatest number of life years and quality-adjusted life-years (QALYs) with higher reductions in hip and vertebral fracture incidence compared with patients with no pharmacologic treatment. The incremental cost-effectiveness ratio (ICER) was 119,575 Thai Baht (THB) per QALY for denosumab versus no pharmacologic treatment and 199,186 THB per QALY for denosumab versus alendronate. Among Thai postmenopausal women with high-risk of fractures, denosumab was cost-effective compared with no pharmacologic treatment at a willingness-to-pay threshold of 160,000 THB per QALY. One-way sensitivity analysis showed models were most sensitive to changes in denosumab pricing. Limitations: Data from other countries used when country-specific data were unavailable may not accurately reflect the true experience in Thailand. The model focused explicitly on hip, vertebral, and wrist fractures, and therefore provides a conservative estimate of the overall potential impact of osteoporosis-related fracture. The fracture risk was not adjusted to reflect potential changes in risk after denosumab treatment discontinuation. Conclusions: In Thailand, denosumab offers a cost-effective osteoporosis treatment option versus no pharmacologic treatment in postmenopausal women at high risk of fracture.

We aim to investigate the nationwide prevalence of asymptomatic radiographic vertebral fracture in Thailand. We found 29% of postmenopausal women had at least one radiographic vertebral fracture. The prevalence was significantly higher among women with osteoporosis at the total hip (TH) region which implies that TH bone mineral density is a determinant of vertebral fracture risk., Introduction: Radiographic vertebral fracture is associated with an increased risk of osteoporotic fracture and mortality in postmenopausal women. We designed a study to determine the prevalence of asymptomatic vertebral fractures in postmenopausal Thai women., Methods: The study was designed as a cross-sectional investigation at five university hospitals so as to achieve representation of the four main regions of Thailand. Radiographs were taken from 1062 postmenopausal women averaging 60 years of age. The presence of vertebral fracture was assessed by the Genant's semiquantitative method with three independent radiologists. Respective bone mineral density was measured by dual-energy X-ray absorptiometry (DEXA) at the lumbar spine (LS), femoral neck (FN), and total hip (TH)., Results: Among the 1062 women, 311 were found to have at least one radiographic vertebral fracture-yielding a prevalence of 29% (95% CI 23.6-32.0%)-and 90 (8.5%, 95% CI 6.8-10.2%) had at least two fractures. The prevalence of vertebral fracture increased with advancing age. Most fractures occurred at one vertebra (71%) and only 29% at multiple vertebrae. The prevalence of vertebral fracture was significantly higher among women with osteoporosis compared with non-osteoporosis at the TH region. There was no significant difference in the prevalence among women with or without osteoporosis at the LS or FN., Conclusions: Radiographic vertebral fractures were common among Thai postmenopausal women (~ 29%). These findings suggest that approximately one in three postmenopausal women has undiagnosed vertebral fracture. Radiographic diagnosis should therefore be an essential investigation for identifying and confirming the presence of vertebral fractures.

The prevalence of nonalcoholic fatty liver disease (NAFLD) is increasing worldwide, including in regions where helminth infections such as the fish-borne liver fluke Opisthorchis viverrini ( Ov ) also occur. We investigated the effects of a high-fat and high-fructose (HFF) diet on the development and progression of NAFLD in experimental opisthorchiasis. Two groups of hamsters were infected with Ov for 4 months before the experiment to induce chronic inflammation. One of these groups ( Ov HFF) was fed with a HFF diet for up to further 4 months. One uninfected group of hamsters served as the normal control group, and another received the HFF diet (HFF group) for up to 4 months. Histopathology, biochemical parameters, and ultrastructural features of liver were investigated. In a short-term treatment, the Ov HFF group showed significantly better homeostatic model assessment for insulin resistance level and lower liver lipid than did the HFF group. By contrast, histopathological characteristics of severe NAFLD were prominent in the Ov HFF group after 4 months on the HFF diet, findings which were supported by confirmatory ultrastructural changes. In conclusion, opisthorchiasis induced the severe NAFLD in hamsters fed high-fat/high-fructose diets.

Accurate measurement of parathyroid hormone (PTH) is crucial for therapeutic decision-making in patients with chronic kidney disease-mineral and bone disorder (CKD-MBD). The second-generation PTH assays, often referred to as "intact PTH" assays, are the current standard and most available assays in clinical practice. However, intact PTH assays measure both full-length biologically active PTH and heterogeneous PTH fragments in the circulation, providing the equivocal value of PTH measurement in patients with CKD-MBD. Due to the variability of PTH assays, preanalytical sample errors, and the phenomenon of end-organ PTH hyporesponsiveness, current CKD-MBD guidelines recommend a wide range for serum PTH targets (2-9 the upper normal limit of the intact PTH assay) in dialysis patients to diminish the risk of developing adynamic bone disease. Nevertheless, a sizeable proportion of CKD patients still experience renal osteodystrophy despite having serum PTH levels within the recommended range. The primary cause of this inconsistency is the analytical interference of various PTH fragments and oxidized PTH forms that considerably accumulate in CKD patients. Therefore, a new mass spectrometry-based assay, which is capable of specifically measuring the whole spectra of PTH fragments, can potentially improve diagnostic accuracy for renal osteodystrophy. However, the effects of different PTH fragments on bone metabolism, vascular calcification, and mortality in CKD patients warrant further research., Competing Interests: The authors report no relevant conflicts of interest., (Copyright © 2019 Kittrawee Kritmetapak and Chatlert Pongchaiyakul.)

The divergence in cardiovascular disease risk among Asian countries may be related to differences in economics, lifestyles, and cultural backgrounds. We examined the differential association of overweight and hypertension between the high- and middle-income Asian countries, namely Japan and Thailand and extended to compare other cardiovascular risk factors between these two countries, using the data sets from the annual health examinations conducted in 127,152 Japanese (mean age, 41.5 ± 11.1 years; mean body mass index [BMI], 22.4 ± 3.4 kg/m 2 ) and 4243 Thai (mean age, 47.9 ± 10.7 years: mean BMI, 24.0 ± 3.7 kg/m 2 ) aged over 18 years with no history of hypertension treatment. Hypertension was diagnosed as office SBP ≥ 130 mmHg and/or office DBP ≥ 80 mmHg. Overweight was defined as BMI ≥ 25 kg/m 2 . The analysis using the direct standardization method showed a lower prevalence of hypertension in the Japanese than in the Thai population (31.8% vs. 57.3%, P < 0.001). The Japanese population had higher estimated glomerular filtration rate and lower cholesterol level and BMI than in the Thai population (all P < 0.001). The association between overweight and hypertension was observed in both populations regardless of age and sex (all P < 0.05). In the analysis stratified by age and sex, the association between overweight and the presence of hypertension was more prominent in the Japanese population aged <50 years in both sexes compared with the Thai population (all P for interaction < 0.001). These results confirmed the differential impact of overweight on hypertension between the high- and middle-income countries even in the similar regions of Asia.

Background: A meal replacement (MR) with a low glycemic index (GI) is possibly beneficial for glycemic control. However, the effects of MR on diabetes mellitus have not been studied among Thai patients with type 2 diabetes (T2DM)., Aim: To compare metabolic outcomes between T2DM patients receiving the new MR formula (ONCE PRO) and normal controlled diets., Methods: A multicenter, open-labeled, randomized controlled trial was conducted. Eligible patients received either ONCE PRO for one meal daily with controlled diets or only controlled diets for 3 months. The differences in metabolic profile between the baseline and end point of each group and between groups were measured., Results: 110 participants were enrolled; the mean difference and standard deviation in hemoglobin A1C (HbA1c) (%) from baseline were -0.21 ± 0.78 ( p = 0.060) and -0.27 ± 0.60 ( p = 0.001) in the MR and control groups, respectively; however, there was no significant difference between groups ( p = 0.637). Patients consuming a MR instead of breakfast had a significant decrease in HbA1c ( p = 0.040). Body weight (BW) and body mass index (BMI) were significantly reduced in both groups. There were no significant change in waist circumference, fasting plasma glucose, total cholesterol and triglycerides. Low-density lipoprotein cholesterol (LDL-C) was significantly decreased in the MR group compared with the control group ( p = 0.049)., Conclusions: Short-term conventional diet control and the low-GI MR product were associated with a decreased BW and BMI. Changes in the other metabolic outcomes, HbA1c, total cholesterol and triglycerides, were comparable despite ONCE PRO as the MR having a better effect on LDL-C lowering.

Background: Despite the abundant sunlight in Thailand, vitamin D deficiency is common in premenopausal and postmenopausal Thai women. Sunlight exposure is a natural way to increase one's intake of vitamin D. However, limited research has been conducted regarding natural exposure to sunlight as a strategy to improve vitamin D status in postmenopausal women., Objective: This study aimed to determine the effects of sunlight exposure compared with oral supplementation with vitamin D2 (weekly 20,000 IU) in combination with sunlight exposure on 25(OH)D levels., Methods: A 12-week randomized controlled trial was conducted in 52 postmenopausal women, age 50-70 years. The participants were randomized to either the sunlight exposure group or the sunlight exposure with vitamin D supplementation group. Serum 25(OH)D concentration and parathyroid hormone (PTH) were measured using standard assays at baseline and 12 weeks., Results: After 12 weeks, mean serum 25(OH)D had decreased from 32.3 to 29.7 ng/ml in the sunlight exposure group, but significantly increased in the combination group (from 29.9 to 32.4 ng/ml). At the end of the study, 25(OH)D levels were significantly higher in the sunlight exposure with vitamin D supplementation group compared with the sunlight exposure group. However, this difference was not observed in women aged >60 years. Serum PTH had decreased in both groups, but not to a significant extent., Conclusion: A combination of weekly vitamin D2 supplementation at a dose of 20,000 IU with sunlight exposure is more effective than sunlight exposure alone in postmenopausal Thai women. Sunlight exposure alone is not sufficient to maintain 25-hydroxyvitamin D levels in this setting., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Introduction: Hypertensive (HT) urgency is a common presentation in emergency room (ER). Although the practice guideline recommends against rapid blood pressure (BP) reduction, in medical practice, physicians usually attempt to timely reduce BP in order to avoid target organ damage. However, there is limited data in Asians. This study was designed to fill the gap of knowledge by using the dataset of the HT crises patients at a tertiary care center., Aim: To determine the characteristics, treatments, and outcomes of HT urgency patients during ER visit and at 2-week follow-up., Methods: A retrospective cohort study conducted at a university hospital in northeast Thailand from January 2012 to June 2017. Hypertensive crises patients were consecutively enrolled., Results: Of the 221,287 patients who admitted to the ER, prevalence rates of HT urgency and HT emergency were 48.5 and 15.5 per 100,000 patients-year. In HT urgency cases, the average initial and discharge SBP/DBP were 200/110 and 163/92 mmHg, respectively. Oral anti-HT medications were most frequently prescribed (90.5%). At a 2-week follow-up, 24.6% of patients had BP < 140/90 mmHg. The SBP at ER discharge was significantly lower in the patients with follow-up BP < 140/90 compared to those with BP > 140/90 mmHg (158.8 ± 16.9 vs. 164.2 ± 16.6 mmHg, P < 0.01)., Conclusions: Hypertensive urgency was common among patients admitted to the ER. Oral anti-HT medication effectively reduced BP. One in five patients had BP < 140/90 mmHg at a 2-week follow-up and systolic BP at discharge might be an important factor in predicting better BP control.

Background: From epidemiologic data, half of hypertensive patients did not achieve the target blood pressure with pharmacotherapy, partly due to poor compliance. Music therapy is an adjunctive therapy which was proved effective for blood pressure reduction. We aimed to investigate the effect of Thai instrumental folk music listening on blood pressure in Thai hypertensive patients., Design, Setting and Subjects: A randomized controlled trial, conducted in the stage-2 hypertensive patients at Srinagarind Hospital, Khon Kaen, Thailand., Methods: One hundred-twenty participants were randomized to music listening group and control group (1:1). The music listening group was assigned to listen to Thai instrumental folk music once a day for one month., Outcome Measures: The primary and secondary outcome measures were home blood pressure (Day 0th and 30th) and office blood pressure (Day 0th and 120th), respectively., Results: Home systolic blood pressure (SBP) and diastolic blood pressure (DBP) in the music listening group were significantly reduced compared with baseline (-9.5 ± 7.1 mmHg (95%CI -11.43, -7.64) and -6.1 ± 5.7 mmHg (95%CI -7.51, -4.53), respectively). Both home SBP and DBP at day 30th of the music listening group were significantly lower than in the control group (-6.0 mmHg (95%CI -8.58, -3.40) and -3.15 mmHg (95%CI -5.20, -1.09), respectively), while the differences of office SBP and DBP between two groups were not significant., Conclusion: This study demonstrated that Thai instrumental folk music listening was effective for SBP and DBP reduction in stage-2 HT patients. This therapy can be used as an alternating approach simultaneously with pharmacological treatment. This trial was registered retrospectively after completion to ClinicalTrials.gov registration number: NCT03381820., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Complications arising from infection with the carcinogenic liver fluke Opisthorchis viverrini cause substantial morbidity and mortality in Thailand and adjacent lower Mekong countries. In parallel, the incidence rate of diabetes mellitus (DM) is increasing in this same region, and indeed worldwide. Many residents in opisthorchiasis-endemic regions also exhibit DM, but the hepatobiliary disease arising during the co-occurrence of these two conditions remains to be characterized. Here, the histopathological profile during co-occurrence of opisthorchiasis and DM was investigated in a rodent model of human opisthorchiasis in which diabetes was induced with streptozotocin. The effects of excretory/secretory products from the liver fluke, O. viverrini (OVES) on hepatocyte and cholangiocyte responses during hyperglycemic conditions also were monitored. Both the liver fluke-infected hamsters (OV group) and hamsters with DM lost weight compared to control hamsters. Weight loss was even more marked in the hamsters with both opisthorchiasis and DM (OD group). Hypertrophy of hepatocytes, altered biliary canaliculi, and biliary hyperplasia were more prominent in the OD group, compared with OV and DM groups. Profound oxidative DNA damage, evidenced by 8-oxo-2'-deoxyguanosine, proliferating cell nuclear antigen, and periductal fibrosis characterized the OD compared to OV and DM hamsters. Upregulation of expression of cytokines in response to infection and impairment of the pathway for insulin receptor substrate (IRS)/phosphatidylinositol-3-kinases (PI3K)/protein kinase B (AKT) signaling attended these changes. In vitro, OVES and glucose provoked time- and dose-dependent effects on the proliferation of both hepatocytes and cholangiocytes. In overview, the co-occurrence of opisthorchiasis and diabetes exacerbated pathophysiological damage to the hepatobiliary tract. We speculate that opisthorchiasis and diabetes together aggravate hepatobiliary pathogenesis through an IRS/PI3K/AKT-independent pathway., Competing Interests: The authors have declared that no competing interests exist.

Background: Renal involvement in type 2 diabetes is mainly due to diabetic nephropathy (DN). Nevertheless, a sizable proportion of diabetic patients could actually have nondiabetic renal diseases (NDRDs) or DN plus NDRDs. This study aimed to explore the pathological features of NDRD in diabetic patients and to assess the predictability of diagnosing NDRD (±DN) versus isolated DN on the basis of clinical parameters., Methods: Medical records of type 2 diabetes patients who underwent renal biopsy under suspicion of NDRD from January 2011 through November 2015 were analyzed retrospectively., Results: A total of 101 patients were enrolled in this study. The most frequent indication for renal biopsy was recent onset of nephrotic syndrome (41%), followed by rapidly progressive renal failure (29%) and active urinary sediment (21%). On renal biopsy, 51% of patients had isolated DN, 20% had isolated NDRD and 29% had DN plus NDRD. IgA nephropathy was the most common cause of isolated NDRD, whereas acute tubular necrosis (39%) and acute interstitial nephritis (33%) were the main causes of NDRD superimposed on DN. Male gender, short-duration diabetes (<8 years), lower glycated hemoglobin and active urinary sediment (≥10 red and white blood cells per high-power field) were independent predictors of NDRD according to multiple logistic regression analysis., Conclusions: Judicious use of renal biopsy revealed NDRD (±DN) in nearly half of type 2 diabetes patients with atypical renal presentation, especially in male patients with well-controlled diabetes, those who have had diabetes for a short duration and those with active urinary sediment.

The adjusted incidence rate of hip fracture in Thailand has increased more than 31% from 1997 to 2006. Mortality and morbidity after hip fracture are also high. One year mortality after a hip fracture has increased from 18% in 1999 to 21% in 2007. The Thai Osteoporosis Foundation (TOPF) developed the first Clinical Practice Guideline (CPG) in 2002 and keeps updating the CPG since then. This latest version of the CPG is our attempt to provide comprehensive positional statement on the diagnosis, prevention and treatment of osteoporosis in Thailand. The study group who revised this position statement contains experts from the TOPF, Four Royal Colleges of Thailand, includes the Orthopaedic Surgeons, Gynecologists and Obstetricians, Physiatrists, Radiologists and 2 Associations of Endocrinologists and Rheumatologists which have involved in the management of patients with osteoporosis.

Background: Point of care testing using glucose meters that measure capillary blood are the most popular and widely used method for the routine monitoring ofblood glucose level. TR UEresult is one ofsuch commonly used blood glucose measuring tools with high accuracy and precision profile according to the manufacturer's data., Objective: To evaluate the performance of TRUEresult in real life practice by examining the agreement between capillary and venous glucose result using TR UEresult and a laboratory plasma glucose., Material and Method: The present study is a cross sectional analytical study. All the data were collected from the patients whose blood samples were drawn for the measurement of plasma glucose at the outpatient department of Srinagarind Hospital, Khon Kaen University Thailand. TR UEresult blood glucose monitoring system was used to perform blood glucose measurement in whole blood samples from capillary and veins. This was compared with plasma glucose result from the automated analyzer in the central laboratory, which was considered as reference method at Srinagarind Hospital., Results: The ISO 15197:2013 criteria was used to determine technical accuracy of the TRUEresult tool. Blood glucose levels in whole blood sample from capillary and veins, as measured using the TRUEresult, were 88.24% and 92.16% of the acceptable bias limits. This is below the minimal acceptable criteria. When Parkes error grid analysis was used to define the significance in clinical decision, all the errors of blood glucose levels measured using the TRUEresult were within zone A and zone B, meaning that the errors have no or little influence on clinical decision., Conclusion: The blood glucose levels in whole bloodfrom capillary and veins measured using TR UEresult blood glucose monitoring was within acceptable accuracy limit. The observed error had no or little influence on clinical decision.

Objective: To assess the efficacy of metformin and insulin in the treatment of pregnant women with gestational diabetes mellitus (GDM)., Methods: A meta-analysis was conducted by including randomized controlled trials comparing metformin and insulin in GDM. An electronic search was conducted to identify relevant studies. Data were synthesized by a random effects meta-analysis model. A Bayesian analysis was also performed to account for uncertainties in the treatment efficacy., Results: Eight clinical trials involving 1712 individuals were included in the final analysis. The pooled estimates of metformin-insulin differences were very small and statistically non-significant in fasting plasma glucose, postprandial plasma glucose and HbA1c, measured at 36-37 weeks of gestation. Notably, 14-46% of those receiving metformin required additional insulin. Compared with the insulin group, metformin treatment was associated with a lower incidence of neonatal hypoglycemia (relative risk, RR 0.74; 95% CI 0.58-0.93; P=0.01) and of neonatal intensive care admission (RR 0.76; 95% CI 0.59-0.97; P=0.03). Bayesian analysis revealed that the efficacy of metformin was consistently higher than insulin with a probability of over 98% on these two neonatal complications. Other outcomes were not significantly different between the two treatment groups., Conclusion: In women with gestational diabetes, metformin use and insulin therapy have comparable glycemic control profile, but metformin use was associated with lower risk of neonatal hypoglycemia., (Copyright © 2015 Elsevier Ireland Ltd.

Background: Early repolarization pattern (ERP) is characterized by J-point elevation with QRS notching or slurring in the terminal portion of the QRS complex. It may be associated with sudden death. Brugada syndrome (BS) is a genetic and fatal disease commonly found in northeastern Thai men. Data on the rate and predictors of ERP in Asian populations are limited. In addition, the correlation between ERP and BS has never been studied in an endemic area of BS. This study aimed to evaluate the prevalence of ERP and its associated factors in young, healthy male Asian subjects., Methods: Between June 2011 and May 2012, 282 young, healthy men aged 20-45 years were enrolled at check-up clinics in Khon Kaen, Thailand. Subjects were divided into the ERP and non-ERP groups., Results: There were 29 subjects with ERP (10.3%). The Sokolow-Lyon index was an independent factor for ERP with an adjusted odds ratio of 1.090 (95% CI: 1.027, 1.159). The Brugada ECG pattern was found in 11 (37.9%) subjects in the ERP group. The Brugada ECG pattern (non-type 1) was commonly found in lateral ERP patients. After the placement of high intercostal leads, the Brugada ECG pattern was dramatically increased compared with results obtained during standard ECG lead placement., Conclusions: The ERP rate in young, healthy men from northeastern Thailand was 10.3%. A higher Sokolow-Lyon index was the only independent factor associated with ERP. Subjects with ERP should be examined with high intercostal leads to uncover Brugada ECG.
