    Objectives: To develop and validate Osteoporosis Prevention and Awareness Tool (OPAAT) in Malaysia.
    Methods: The OPAAT was modified from the Malaysian Osteoporosis Knowledge Tool and developed from an exploratory study on patients. Face and content validity was established by an expert panel. The OPAAT consists of 30 items, categorized into three domains. A higher score indicates higher knowledge level. English speaking non-osteoporotic postmenopausal women 50 years of age and pharmacists were included in the study.
    Results: A total of 203 patients and 31 pharmacists were recruited. Factor analysis extracted three domains. Flesch reading ease was 59.2. The mean±SD accuracy rate was 0.60±0.22 (range: 0.26-0.94). The Cronbach’s α for each domain ranged from 0.286-0.748. All items were highly correlated (Spearman’s rho: 0.761-0.990, p<0.05), with no significant change in the overall test-retest scores, indicating that OPAAT has achieved stable reliability. Pharmacists had higher knowledge score than patients (80.9±8.7vs63.6±17.4, p<0.001), indicating
    that the OPAAT was able to discriminate between the knowledge levels of pharmacists and patients.
    Conclusion: The OPAAT was found to be a valid and reliable instrument for assessing patient’s knowledge about osteoporosis and its prevention in Malaysia. The OPAAT can be used to identify individuals in need of osteoporosis educational intervention.

    Background Population screening for osteoporosis using bone mineral density scan is not feasible in Malaysia as this test is costly. Hence, there is a need to develop a more efficient method to screen for osteoporosis.Objectives To determine the feasibility of an interprofessional collaborative osteoporosis screening programme (IPC-OSP). Methods Postmenopausal women aged ≥ 50 years, who had not been diagnosed with osteoporosis were recruited from a primary care clinic from June to August 2014. Patients were assessed for their osteoporosis risk and were counselled on prevention methods. Patients at risk were referred to the doctor with a recommendation for a bone mineral density (BMD) scan. Results Fifty out of 55 patients were recruited (response rate = 90.9%). A total 26/50 (52.0%) went for a bone mineral density scan, none were osteoporotic, 17/50 (34%) were osteopenic, 2/50 (4.0%), were started on osteoporosis medications and 14/50 (28%) modified their lifestyle to improve bone health or started on calcium supplements. Osteoporosis knowledge significantly increased from baseline to month two (46.3 ± 21.4 vs. 79.1 ± 14.3, p

    OBJECTIVE: The study aims to identify the risk of obtaining a fracture among post-menopausal women with osteopenia and osteoporosis.

    METHOD: This work was a cross-sectional study involving a purposive sample of 87 post-menopausal women who attended the orthopedic and menopause clinics of Hospital Tengku Ampuan Afzan, Kuantan. The data were entered into the WHO fracture risk assessment tool (FRAX®) to predict major fracture and risk for hip fracture in 10 years' time.

    RESULTS: The mean age of the respondents was 61.6 years (SD=7.9). Among the respondents, 50.6% had osteopenia and nearly half (48.3%) had osteoporosis. The mean number of menopausal years of the respondents was 11.9 (SD=8.5), ranging between 1 and 44 years. The FRAX findings indicated 9.7% major osteoporotic fracture probability and 3.5% hip fracture probability, which were denoted as high risk. A Pearson correlation coefficient was computed to assess the relationship between menopausal years and the FRAX major osteoporotic fracture probability. A significant positive correlation was found between the two, but the correlation was weak (r=0.581, n=87, p < 0.001).

    CONCLUSIONS: The present findings indicate that menopausal years have a positive correlation with the risk of obtaining a fracture.

    This study examined the relationship between reproductive characteristics and bone mineral density (BMD) in postmenopausal women who had been referred to the menopause clinics of the National Population and Family Development Board and of the Hospital Kuala Lumpur from July 2011 to January 2012. The participants of this study were 201 postmenopausal Malaysian women aged 45-71 years. Some socio-demographic, lifestyle, and reproductive factors were recorded. Calcaneal BMD was measured by quantitative ultra-sonography. Correlations of reproductive factors with BMD were assessed by Pearson's correlation test and multiple regression analysis. Age at menopause was not significantly correlated with BMD, while the years after menopause, age at the first menstrual period, number of pregnancies, and total lactation periods were inversely correlated with it. Among reproductive factors, only the association between lactation duration and BMD remained significant after adjusting for age, body mass index, activity, and calcium intake. The results indicated that except for prolonged total time of lactation, other reproductive factors were not significantly associated with BMD in postmenopausal women.

    The interaction of dietary and genetic factors may affect the development of bone deterioration. This study investigated whether the effects of dietary acid load (DAL) on bone loss in postmenopausal Chinese women were moderated by the insulin-like growth factor-1 (IGF-1) single nucleotide polymorphism, a known gene that plays a role in the regulation of bone formation and bone remodeling. A total of 217 healthy participants were recruited from the National Council of Senior Citizens Organizations Malaysia. Serum collagen type 1 cross-linked C-telopeptide was used as a surrogate bone marker to assess bone resorption and Agena® MassARRAY genotyping analysis was used to identify the signaling of IGF-1 rs35767. The dietary acid load was measured by potential renal acid load score while physical activity was ascertained using the Global Physical Activity Questionnaire. Hierarchical regression was applied to test the main and interaction effects of DAL and IGF-1 genotypes in bone resorption. The result supported the diet-dependent acid-base balance theory that higher DAL was positively associated with bone resorption (β = 0.152, p = 0.031, F(6,207) = 2.11, sig-F = 0.036, R² = 0.079). However, the results indicated that there was no significant correlation between IGF-1 and bone resorption, or any significant interaction between DAL and IGF-1. In conclusion, there was no moderating effect of IGF-1 on the relationship between DAL and bone resorption.

    Osteoporosis is a pathologic process characterized by low bone mass with skeletal fragility and an increased risk of fracture. It occurs due to an imbalance between bone resorption and formation. Although current antiresorptive therapy halts bone loss, it does not cure the condition as it also inhibits bone formation. Recent preclinical and clinical trials suggest that the inhibition of resorption by cathepsin K inhibitors increases bone formation. Cathepsin K is a papainlike cysteine protease with high potent collagenase activity and predominantly expressed in osteoclasts. While allowing demineralization, cathepsin K inhibitors suppress the degradation of type I collagen (the major organic matrix of bone) and thus enhancing bone formation. Many of these inhibitors have passed preclinical studies and are presently in clinical trials at different stages of advancement. This review explores the promising role of cathepsin K as a novel antiresorptive for the treatment of osteoporosis.

    OBJECTIVES: To develop and validate the Osteoporosis Patient Satisfaction Questionnaire (OPSQ) and to assess the opinion of postmenopausal osteoporotic women towards pharmaceutical care.
    METHODS: A 16-item instrument was designed. Each response consists of a five-point Likert-like scale with higher scores indicating greater satisfaction. The face and content validity was established via consultation with an endocrinologist and three pharmacists as well as feedback from participants in a preliminary study. Postmenopausal osteoporotic women taking bisphosphonates were recruited and randomly allocated to the intervention (n=90) and control groups (n=90). Pharmaceutical care was provided at month 2 to the intervention group while the control group received standard pharmacy services. The OPSQ was administered at month 6 (end of the intervention period), to assess patients' satisfaction. Factor analysis was performed using varimax rotation. Internal reliability was established using Cronbach's alpha. Construct validity was performed by using the Mann-Whitney U test.
    RESULTS: The internal reliability of the OPSQ produced a Cronbach's alpha of 0.86. Factor analysis identified one component in the OPSQ, which measured patient satisfaction. The intervention group showed significantly better overall OPSQ score than the control group (91.89+/-7.22% versus 84.32+/-7.48%, p<0.001). This indicates that the OPSQ was able to differentiate between participants who received pharmaceutical care from those who did not.
    CONCLUSIONS: The 16-item OPSQ developed in this study has high internal reliability and is a valid instrument for assessing osteoporotic women's satisfaction with pharmaceutical care service in Malaysia.

    INTRODUCTION: Osteoporosis is a major health concern in postmenopausal women, and oxidative stress contributes to the development of bone loss. Cellular studies and ovariectomised rat model mimicking bone loss in postmenopausal women show the bone-protective effect of tocotrienols (TTs) with antioxidant capability. We aim to access the safety and efficacy of TT consumption for bone health in postmenopausal women.

    METHODS AND ANALYSIS: In this 12-week randomised double-blinded placebo-controlled trial for the effects of dietary TT supplementation in postmenopausal women, postmenopausal women aged 45 years and older with at least 1 year after menopause and bone mineral density T-score at the spine and/or hip 2.5 or more below the reference values will be randomly assigned to 3 daily supplements: (1) placebo group receiving 860 mg olive oil, (2) low TT group receiving 430 mg of 70% pure TTs (containing 300 mg TT) and (3) high TT group receiving 860 mg of 70% pure TTs (600 mg TT). The primary outcome measure will be urinary N-terminal telopeptide. The secondary outcome measures will be serum bone-specific alkaline phosphatase, receptor activator of nuclear factor-κB ligand, osteoprotegerin, urinary 8-hydroxy-2'-deoxyguanosine and quality of life. At 0, 6 and 12 weeks, the following will be assessed: (1) primary and secondary outcome measures; (2) serum TT and tocopherol concentrations; (3) physical activity and food frequency questionnaires. Liver function will be monitored every 6 weeks for safety. 'Intent-to-treat' principle will be employed for data analysis. A model of repeated measurements with random effect error terms will be applied. Analysis of covariance, χ2 analysis and regression will be used for comparisons.

    ETHICS AND DISSEMINATION: This study was approved by the Bioethics Committee of the Texas Tech University Health Sciences Center. The findings of this trial will be submitted to a peer-reviewed journal in the areas of bone or nutrition and international conferences.

    OBJECTIVE: Accelerated bone loss that occurs in postmenopausal women has been linked to oxidative stress and increased free radicals. We propose the use of antioxidants to prevent and reverse postmenopausal osteoporosis. This study aimed to examine the effects of tocotrienol, a vitamin E analog, on bone loss due to estrogen deficiency. Our previous study showed that tocotrienol increased the trabecular bone volume and trabecular number in ovariectomized rats. In the current study, we investigated the effects of tocotrienol supplementation on various biochemical parameters in a postmenopausal osteoporosis rat model.

    MATERIALS AND METHODS: A total of 32 female Wistar rats were randomly divided into four groups. The baseline group was sacrificed at the start of the study, and another group was sham operated. The remaining rats were ovariectomized and either given olive oil as a vehicle or treated with tocotrienol at a dose of 60 mg/kg body weight. After four weeks of treatment, blood was withdrawn for the measurement of interleukin-1 (IL1) and interleukin-6 (IL6) (bone resorbing cytokines), serum osteocalcin (a bone formation marker) and pyridinoline (a bone resorption marker).

    RESULTS: Tocotrienol supplementation in ovariectomized rats significantly reduced the levels of osteocalcin, IL1 and IL6. However, it did not alter the serum pyridinoline level.

    CONCLUSION: Tocotrienol prevented osteoporotic bone loss by reducing the high bone turnover rate associated with estrogen deficiency. Therefore, tocotrienol has the potential to be used as an anti-osteoporotic agent in postmenopausal women.

    Dietary studies often report low calcium intake amongst post-menopausal Malaysian women and calcium deficiency has been implicated as part of the etiology of age-related bone loss leading to osteoporosis. Therefore, the objective of this study was to examine the effectiveness of high calcium skimmed milk (Anlene Gold, New Zealand Milk, Wellington, New Zealand) to reduce bone loss in Chinese postmenopausal women. Two hundred subjects aged 55-65 years and who were more than 5 years postmenopausal were randomized to a milk group and control group. The milk group consumed 50 g of high calcium skimmed milk powder daily, which contained 1200 mg calcium (taken as two glasses of milk a day). The control group continued with their usual diet. Using repeated measures ANCOVA, the milk supplement was found to significantly reduce the percentage of bone loss at the total body compared to the control group at 24 months (control -1.04%, milk -0.13%; P<0.001). At the lumbar spine, the percentage of bone loss in the control group was significantly higher (-0.90%) when compared to the milk (-0.13%) supplemented group at 24 months (P<0.05). Similarly, milk supplementation reduced the percentage of bone loss at the femoral neck (control -1.21%, milk 0.51%) (P<0.01) and total hip (control -2.17%, milk -0.50%) (P<0.01). The supplemented group did not experience any significant weight gain over the 24 months. The serum 25-hydroxy vitamin D level improved significantly (P<0.01) from 69.1 +/- 16.1 nmol/l at baseline to 86.4 +/- 22.0 nmol/l at 24 months in the milk group. In conclusion, ingestion of high calcium skimmed milk was effective in reducing the rate of bone loss at clinically important lumbar spine and hip sites in postmenopausal Chinese women in Malaysia. Supplementing with milk had additional benefits of improving the serum 25-hydroxy vitamin D status of the subjects.

    Oxidative stress has been associated with postmenopausal osteoporosis which pre-disposes to risk of fracture. Palm tocotrienol is a potent antioxidant and has the poten-tial to be used for treatment of post-menopausal osteoporosis. The aim of the study is to determine if palm tocotrienol supplementation could alleviate oxidative stress in ovariectomised rat model and improve its bone strength. The rats were di- vided into four groups: (i) sham-operated  group (SHAM) (ii) ovariectomised-control group (OVX) (iii) ovariectomised and given 60mg/kg α-tocopherol by oral gavage (OVX + ATF) (iv) ovariectomised and given 60mg/kg palm tocotrienols by oral gavage (OVX + PTT). After eight weeks of treatment, blood samples were taken to measure oxida-tive status (MDA, SOD and GPX) while the femurs were biomechanically tested for strength and resistance to fracture. Ovariectomy was shown to induce oxidative stress as shown by the raised MDA levels and reduced GPX activity. Palm tocotrienols seemed to offer protection against the ovariectomy-induced oxidative stress as shown by the suppression of MDA levels and raised GPX and SOD activities in the OVX+PTT group. In comparison, α-tocopherol was only able to raise the SOD but not as high as palm tocotrienols. The biomechanical tests have shown that ovariectomy has not af-fected the bone strength significantly after eight weeks. Palm tocotrienols supplemen-tation for eight weeks was effective in preventing oxidative stress in a post-meno-pausal rat.

    Osteoporosis is considered a serious debilitating disease. Cosmos caudatus (ulam raja), a plant containing antioxidant compounds and minerals, may be used to treat and prevent osteoporosis. This study determines the effectiveness of C. caudatus as bone protective agent in postmenopausal osteoporosis rat model. Thirty-two female rats, aged 3 months old, were divided into 4 groups. Group one was sham operated (sham) while group two was ovariectomized. These two groups were given ionized water by forced feeding. Groups three and four were ovariectomized and given calcium 1% ad libitum and force-fed with C. caudatus at the dose of 500 mg/kg, respectively. Treatments were given six days per week for a period of eight weeks. Body weight was monitored every week and structural bone histomorphometry analyses of the femur bones were performed. Ovariectomy decreased trabecular bone volume (BV/TV), decreased trabecular number (Tb.N), and increased trabecular separation (Tb.Sp). Both calcium 1% and 500 mg/kg C. caudatus reversed the above structural bone histomorphometric parameters to normal level. C. caudatus shows better effect compared to calcium 1% on trabecular number (Tb.N) and trabecular separation (Tb.Sp). Therefore, Cosmos caudatus 500 mg/kg has the potential to act as the therapeutic agent to restore bone damage in postmenopausal women.

    Osteoporosis is a metabolic disease affecting both men and women especially in postmenopausal women. Curcumin possesses many medicinal properties. In this study, thirty two female Sprague-Dawley rats were used to determine the potential effect of curcumin in prevention of bone loss following ovariectomy. The animals were divided into Sham group, ovariectomised control, ovariectomised treated with curcumin 110 mg/kg and ovariectomised treated with Premarin 100 μg/kg. The treatments were given via daily oral gavages for 60 days. The structural parameters such as bone volume, trabecular number, trabecular thickness and trabecular separation were found to be deteriorated in ovariectomised rats compared to Sham group. Moreover, the reduced osteoblast count, the increased osteoclast count and increased eroded surface were found in ovariectomised groups. Treatment with curcumin was able to reverse all these ovariectomy-induced deteriorations. Curcumin treatment was as effective as Premarin in most parameters except the bone volume and eroded surface, which were better than Premarin. The high dose of curcumin treatment was not only able to reduce the osteoclast number but also increase the osteoblast count. Therefore, the potential effect of curcumin can be applied as an alternative to oestrogen for prevention of postmenopausal osteoporosis.

    Oxidative stress and free radicals have been implicated in the pathogenesis of osteoporosis. Therefore, antioxidant compounds have the potential to be used in the prevention and treatment of the disease. In this study, we investigated the effects of virgin coconut oil (VCO) on bone microarchitecture in a postmenopausal osteoporosis rat model. VCO is a different form of coconut oil as it is rich with antioxidants. Three-month-old female rats were randomly grouped into baseline, sham-operated, ovariectomized control (Ovx), and ovariectomized rats fed with 8% VCO in their diet for six weeks (Ovx+VCO). Bone histomorphometry of the right femora was carried out at the end of the study. Rats supplemented with VCO had a significantly greater bone volume and trabecular number while trabecular separation was lower than the Ovx group. In conclusion, VCO was effective in maintaining bone structure and preventing bone loss in estrogen-deficient rat model.

    BACKGROUND: Osteoporotic fracture is a major health burden. Early diagnosis and management would improve the quality of life and reduce costs to the society.
    OBJECTIVE: We aimed to identify risk factors associated with osteoporosis followed by development and validation of a screening tool in the hope of providing an appropriate regime to detect low bone density (BMD) in Malaysia.
    METHODOLOGY: Between November 1999 and November 2002, 514 healthy women aged ≥ 45 with intact uterus, non-HRT users were recruited. Following BMD testing, a screening tool was developed. For validation, 72 women were recruited from June 2003 to December 2003.
    RESULTS: Age and a longer duration postmenopause were negatively linked to BMD. Higher family income, BMI, waist and hip circumference were positively correlated. A score of ≥ 4, the screening tool had a sensitivity of 73.2%, a specificity of 61.6% for identifying women with low BMD (T score ≤ -2) plus a sensitivity of 80.2% in selecting women with osteoporosis. The tool enabled a 45.9% reduction in unnecessary DEXA testing. Validation of the screening tool showed a negative predictive value of 97.8%, sensitivity and specificity of 87.5% and 70.3%, respectively.
    CONCLUSION: The Malaysian Osteoporosis Screening Tool (MOST) is relatively simple. Its usage may reduce unnecessary DEXA test.

    We evaluated adherence with raloxifene therapy compared with daily bisphosphonate in Asian postmenopausal women at increased risk of osteoporotic fractures. In this 12-month observational study conducted in Asia (Hong Kong, Malaysia, Pakistan, Philippines, Singapore, Taiwan), 984 postmenopausal women (aged 55 years or older) were treated with raloxifene 60 mg/day (n = 707; 72%) or daily bisphosphonate (alendronate 10 mg/day; n = 206; 21%, or risedronate 5 mg/day; n = 71; 7%) during their normal course of care. Patients were assessed at baseline, 6, and 12 months. Baseline characteristics (including age, race, education, menopausal status, and baseline fractures) were comparable between the raloxifene and bisphosphonate groups. More women on raloxifene completed the study compared with those on bisphosphonate (50.2% versus 37.5%; P < 0.001). Patients also took raloxifene for a longer period than bisphosphonate (median, 356 versus 348 days; P = 0.011). Compared with those taking bisphosphonate, significantly fewer patients taking raloxifene discontinued the study because of stopping treatment (5.7% versus 10.1%, P = 0.017) or changing treatment (2.8% versus 9.7%, P < 0.001). Inconvenient dosing was reported as a primary reason for discontinuation due to stopping or changing treatment in 19 (6.9%) bisphosphonate patients compared with 0 raloxifene patients. The percentage of patients who had consumed 80% or more of their study medication was similar for raloxifene patients (48-56 weeks; 95.2%) and bisphosphonate patients (48-56 weeks; 93.3%). More raloxifene patients responded that they were satisfied with their medication than bisphosphonate patients at 48-56 weeks (P = 0.002). We concluded that Asian postmenopausal women at increased risk of osteoporotic fractures showed a greater propensity to remain on raloxifene compared with bisphosphonate. The women on raloxifene exhibited lower discontinuation rates and higher treatment satisfaction.

    BACKGROUND AND OBJECTIVES: Vitamin D3 (cholecalciferol) dose required to maintain sufficiency in non- Caucasian women with postmenopausal osteoporosis (PMO) inthe tropics has not been well studied. Some guidelines mandate 800-1000 IU vitamin D/day but the Endocrine Society (US) advocates 1500-2000 IU/day to maintain 25-hydroxyvitamin-D (25(OH)D) concentration at >75 nmol/L. We aimed to establish oral cholecalciferol dose required to maintain 25(OH)D concentration at >75 nmol/L in PMO Chinese Malaysian women, postulating lower dose requirements amongst light-skinned subjects in the tropics.

    METHODS AND STUDY DESIGN: 90 Chinese Malaysian PMO women in Kuala Lumpur, Malaysia (2°30'N) with baseline serum 25(OH)D levels >=50 nmol/L were recruited. Prior vitamin D supplements were discontinued and subjects randomized to oral cholecalciferol 25,000 IU/4-weekly (Group-A) or 50,000 IU/4-weekly (Group- B) for 16 weeks, administered under direct observation. Serum 25(OH)D, PTH, serum/urinary calcium were measured at baseline, 8 and 16 weeks.

    RESULTS: Baseline characteristics, including osteoporosis severity, sun exposure (~3 hours/week), and serum 25(OH)D did not differ between treatment arms. After 16 weeks, 91% of women sufficient at baseline, remained sufficient on 25,000 IU/4-weekly compared with 97% on 50,000 IU/4-weekly with mean serum 25(OH)D 108.1±20.4 and 114.7±18.4 SD nmol/L respectively (p=0.273). At trial's end, 39% and 80% of insufficient women at baseline attained sufficiency in Group A and Group B (p=0.057). Neither dose was associated with hyperparathyroidism or toxicity.

    CONCLUSIONS: Despite pretrial vitamin D supplementation and adequate sun exposure, 25.6% Chinese Malaysian PMO women were vitamin D insufficient indicating sunshine alone cannot ensure sufficiency in the tropics. Both ~900 IU/day and ~1800 IU/day cholecalciferol can safely maintain vitamin D sufficiency in >90% of Chinese Malaysian PMO women. Higher doses are required with baseline concentration <75 nmol/L.
