    Guidance is provided in an international setting on the assessment and specific treatment of postmenopausal women at low, high and very high risk of fragility fractures.

    INTRODUCTION: The International Osteoporosis Foundation and European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis published guidance for the diagnosis and management of osteoporosis in 2019. This manuscript seeks to apply this in an international setting, taking additional account of further categorisation of increased risk of fracture, which may inform choice of therapeutic approach.

    METHODS: Clinical perspective and updated literature search.

    RESULTS: The following areas are reviewed: categorisation of fracture risk and general pharmacological management of osteoporosis.

    CONCLUSIONS: A platform is provided on which specific guidelines can be developed for national use to characterise fracture risk and direct interventions.

    OBJECTIVES: Hip fracture is a major public health problem. Earlier studies projected that the total number of hip fracture will increase dramatically by 2050, and most of the hip fracture will occur in Asia. To date, only a few studies provided the updated projection, and none of them focused on the hip fracture projection in Asia. Thus, it is essential to provide the most up to date prediction of hip fracture in Asia, and to evaluate the total direct medical cost of hip fracture in Asia.

    METHODS: We provide the updated projection of hip fracture in 9 Asian Federation of Osteoporosis Societies members using the most updated incidence rate and projected population size.

    RESULTS: We show that the number of hip fracture will increase from 1,124,060 in 2018 to 2,563,488 in 2050, a 2.28-fold increase. This increase is mainly due to the changes on the population demographics, especially in China and India, which have the largest population size. The direct cost of hip fracture will increase from 9.5 billion United State dollar (USD) in 2018 to 15 billion USD in 2050, resulting a 1.59-fold increase. A 2%-3% decrease in incidence rate of hip fracture annually is required to keep the total number of hip fracture constant over time.

    CONCLUSIONS: The results show that hip fracture remains a key public health issue in Asia, despite the available of better diagnosis, treatment, and prevention of fracture over the recent years. Healthcare policy in Asia should be aimed to reduce the burden of hip fracture.

    Genetic diversity and patterns of population structure of the 94 oil palm lines were investigated using species-specific simple sequence repeat (SSR) markers. We designed primers for 63 SSR loci based on their flanking sequences and conducted amplification in 94 oil palm DNA samples. The amplification result showed that a relatively high level of genetic diversity was observed between oil palm individuals according a set of 21 polymorphic microsatellite loci. The observed heterozygosity (Ho) was 0.3683 and 0.4035, with an average of 0.3859. The Ho value was a reliable determinant of the discriminatory power of the SSR primer combinations. The principal component analysis and unweighted pair-group method with arithmetic averaging cluster analysis showed the 94 oil palm lines were grouped into one cluster. These results demonstrated that the oil palm in Hainan Province of China and the germplasm introduced from Malaysia may be from the same source. The SSR protocol was effective and reliable for assessing the genetic diversity of oil palm. Knowledge of the genetic diversity and population structure will be crucial for establishing appropriate management stocks for this species.

    X-linked hypophosphatemia (XLH) is a rare, inherited, multisystem disorder characterized by hypophosphatemia that occurs secondary to renal phosphate wasting. Mutations in PHEX gene (located at Xp22.1) in XLH alter bone mineral metabolism, resulting in diverse skeletal, dental, and other extraskeletal abnormalities that become evident in early childhood and persist into adolescence and adult life. XLH impacts physical function, mobility, and quality of life, and is associated with substantial socioeconomic burden and health care resource utilization. As the burden of illness varies with age, an appropriate transition of care from childhood and adolescence to adulthood is necessary to meet growth-related changes and minimize long-term sequelae of the condition. Previous XLH guidelines that encompassed transition of care have focused on Western experience. Regional differences in resource availability warrant tailoring of recommendations to the Asia-Pacific (APAC) context. Hence, a core expert panel of 15 pediatric and adult endocrinologists from nine countries/regions across APAC convened to formulate evidence-based recommendations for optimizing XLH care. A comprehensive literature search on PubMed using MeSH and free-text terms relevant to predetermined clinical questions on diagnosis, multidisciplinary management, and transition of care of XLH revealed 2171 abstracts. The abstracts were reviewed independently by two authors to shortlist a final of 164 articles. A total of 92 full-text articles were finally selected for data extraction and drafting the consensus statements. Sixteen guiding statements were developed based on review of evidence and real-world clinical experience. The GRADE criteria were used to appraise the quality of evidence supporting the statements. Subsequently, a Delphi technique was utilized to rate the agreement on statements; 38 XLH experts (15 core, 20 additional, 3 international) from 15 countries/regions (12 APAC, 3 EU) participated in the Delphi voting to further refine the statements. Statements 1-3 cover the screening and diagnosis of pediatric and adult XLH; we have defined the clinical, imaging, biochemical, and genetic criteria and raised red flags for the presumptive and confirmatory diagnosis of XLH. Statements 4-12 tackle elements of multidisciplinary management in XLH such as therapeutic goals and options, composition of the multidisciplinary team, follow-up assessments, required monitoring schedules, and the role of telemedicine. Treatment with active vitamin D, oral phosphate, and burosumab is discussed in terms of applicability to APAC settings. We also expound on multidisciplinary care for different age groups (children, adolescents, adults) and pregnant or lactating women. Statements 13-15 address facets of the transition from pediatric to adult care: targets and timelines, roles and responsibilities of stakeholders, and process flow. We explain the use of validated questionnaires, desirable characteristics of a transition care clinic, and important components of a transfer letter. Lastly, strategies to improve XLH education to the medical community are also elaborated in statement 16. Overall, optimized care for XLH patients requires prompt diagnosis, timely multidisciplinary care, and a seamless transfer of care through the coordinated effort of pediatric and adult health care providers, nurse practitioners, parents or caregivers, and patients. To achieve this end, we provide specific guidance for clinical practice in APAC settings. © 2023 The Authors.

    Postmenopausal women are at significant risk for osteoporotic fractures due to their rapid bone loss. Half of all postmenopausal women will get an osteoporosis-related fracture over their lifetime, with 25% developing a spine deformity and 15% developing a hip fracture. By 2050, more than half of all osteoporotic fractures will occur in Asia, with postmenopausal women being the most susceptible. Early management can halt or even reverse the progression of osteoporosis. Consequently, on October 31, 2020, the Taiwanese Osteoporosis Association hosted the Asia-Pacific (AP) Postmenopausal Osteoporotic Fracture Prevention (POFP) consensus meeting, which was supported by the Asian Federation of Osteoporosis Societies (AFOS) and the Asia Pacific Osteoporosis Foundation (APOF). International and domestic experts developed ten applicable statements for the prevention of osteoporotic fractures in postmenopausal women with low bone mass or osteoporosis but no fragility fractures in the AP region. The experts advocated, for example, that postmenopausal women with a high fracture risk be reimbursed for pharmaceutical therapy to prevent osteoporotic fractures. More clinical experience and data are required to modify intervention tactics.

    Osteoporosis is a major health issue. By 2050, a greater than 2-fold increase in patients number with hip fractures will occur in Asia representing 50% of all hip fractures worldwide. For the Asia-Pacific (AP) region, more efforts on controlling osteoporosis and the subsequent fractures are crucial. Bone mineral density (BMD) by dual energy X-ray absorptiometry (DXA) is commonly used to diagnose osteoporosis and monitor osteoporosis treatment. However, the inconvenience, cost, limited availability of DXA and the delay in detection of BMD changes after treatment initiation support an important role for bone turnover markers (BTMs), as short-term tools to monitor therapy. With regards to low adherence rates of medical treatment of osteoporosis, the experts reached consensus on the use of BTMs for both raising awareness and short-term monitoring of osteoporosis treatment in the AP region. The experts endorse the use of BTMs, especially serum C-terminal telopeptide of type 1 collagen (CTX) and serum procollagen type 1 N propeptide (P1NP), as short-term monitoring tools to help clinicians assess the responses to osteoporosis therapies and appropriately adjust treatment regimens earlier than BMD. Either the absolute values or the degree of change from baseline in BTMs can be used to monitor the potential efficacy of osteoporosis therapies. The use of BTMs can be incorporated in osteoporosis care programs, such as fracture liaison service (FLS), to improve patient adherence and treatment outcomes. Encouraging sufficient reimbursement from health care systems may facilitate widespread use of BTMs in clinical practice in the AP region.

    The Fracture Liaison Service (FLS) Consensus Meeting endorsed by the International Osteoporosis Foundation (IOF), Asian Federation of Osteoporosis Societies (AFOS), and Asia Pacific Osteoporosis Foundation (APOF) was hosted by the Taiwanese Osteoporosis Association on October 14, 2017. International and domestic experts reviewed the 13 Best Practice Framework (BPF) standards and concluded that all standards were generally applicable in the Asia-Pacific region and needed only minor modifications to fit the healthcare settings in the region.

    PURPOSE: To review and generate consensus on best practices of fracture liaison service (FLS) in the Asia-Pacific (AP) region.

    METHODS: In October 2017, the Taiwanese Osteoporosis Association (TOA) invited experts from the AP region (n = 23), the Capture the Fracture Steering Committee (n = 2), and the USA (n = 1) to join the AP region FLS Consensus Meeting in Taipei. After two rounds of consensus generation, the recommendations on the 13 Best Practice Framework (BPF) standards were reported and reviewed by the attendees. Experts unable to attend the on-site meeting reviewed the draft, made suggestions, and approved the final version.

    RESULTS: Because the number of FLSs in the region is rapidly increasing, experts agreed that it was timely to establish consensus on benchmark quality standards for FLSs in the region. They also agreed that the 13 BPF standards and the 3 levels of standards were generally applicable, but that some clarifications were necessary. They suggested, for example, that patient and family education be incorporated into the current standards and that communication with the public to promote FLSs be increased.

    CONCLUSIONS: The consensus on the 13 BPF standards reviewed in this meeting was that they were generally applicable and required only a few advanced clarifications to increase the quality of FLSs in the region.

    High-density single nucleotide polymorphisms (SNPs) are used as highly favored makers to analyze genetic diversity and population structure, to construct high-density genetic maps and provide genotypes for genome-wide association analysis. In order to develop genome-wide SNP markers in oil palm (Elaeis guineensis), single locus amplified fragment sequencing (SLAF-seq) technology was performed in a diversity panel of 200 oil palm individuals and 1,261,501 SNPs were identified with minor allele frequency > 0.05 and integrity > 1. Among them, only 17.81% can be mapped within the genic region and the remaining was located into the intergenic region. A positive correlation was detected between the distribution of SNP markers and retrotransposons [transposable elements (TEs)]. Population structure analysis showed that the 200 individuals of oil palm can be divided into five subgroups based on cross-validation errors. However, the subpopulations divided for the 200 oil palm individuals based on the SNP markers were not accurately related to their geographical origins and 80 oil palm individuals from Malaysia showed highest genetic diversity. In addition, the physical distance of linkage disequilibrium (LD) decay in the analyzed oil palm population was 14.516 kb when r2 = 0.1. The LD decay distances for different chromosomes varied from 3.324 (chromosome 15) to 19.983 kb (chromosome 7). Our research provides genome-wide SNPs for future targeted breeding in palm oil.

    OBJECTIVE: Glucose disorders and dyslipidemia are closely associated with obesity and metabolic disease. The purpose of this study was to investigate the effect of Carnosine supplementation on lipid profile, fasting blood glucose, HbA1C and Insulin resistance.

    METHOD: MEDLINE/PubMed, Scopus and Web of sciences were investigated to identify relevant articles up to June 2019. The search strategy combined the Medical Subject Heading and Title and/or abstract keywords. The combined effect sizes were calculated as weight mean difference (WMD) using the random-effects model. Between study heterogeneity was evaluated by the Cochran's Q test and I2.

    RESULTS: Four RCTs studies investigated Carnosine use versus any control for at least 2 weeks were identified and analyzed. Overall results from the random-effects model on included studies, with 184 participants, indicated that carnosine intervention reduced HbA1C levels in intervention vs control groups (WMD: -0.92 %, 95 % CI: -1.20, -0.63, I2:69 %). Four studies, including a total of 183 participants, reported TG changes as an outcome measure variable, but combined results did not show significant reduction in this outcome (WMD: -14.46 mg/dl, 95 % CI: -29.11, 0.19, I2:94 %). Furthermore, combined results did not show any significant change in HOMA-IR, Cholesterol, fasting blood sugar, or HDL-C.

    CONCLUSION: Carnosine supplementation results in a decrease in HbA1C, but elicits no effect on HOMA-IR, Cholesterol, fasting blood sugar, TG and HDL-C. Future studies with a larger sample sizes, varied doses of carnosine, and population-specific sub-groups are warranted to confirm, and enhance, the veracity of our findings.

    KEY MESSAGE: This study highlights the changes in umami-related nucleotide and glutamate levels when the AMP deaminase gene was elevated in transgenic tomato. Taste is perceived as one of a combination of five sensations, sweet, sour, bitter, salty, and umami. The umami taste is best known as a savoury sensation and plays a central role in food flavour, palatability, and eating satisfaction. Umami flavour can be imparted by the presence of glutamate and is greatly enhanced by the addition of ribonucleotides, such as inosine monophosphate (IMP) and guanosine monophosphate (GMP). The production of IMP is regulated by the enzyme adenosine monophosphate (AMP) deaminase which functions to convert AMP into IMP. We have generated transgenic tomato (Solanum lycopersicum) lines over expressing AMP deaminase under the control of a fruit-specific promoter. The transgenic lines showed substantially enhanced levels of AMP deaminase expression in comparison to the wild-type control. Elevated AMP deaminase levels resulted in the reduced accumulation of glutamate and increased levels of the umami nucleotide GMP. AMP concentrations were unchanged. The effects on the levels of glutamate and GMP were unexpected and are discussed in relation to the metabolite flux within this pathway.

    BACKGROUND AND AIM: Previous studies lack consistent conclusions as to whether astaxanthin is actually linked to various health benefits as claimed. Here, we attempt to unravel the association of astaxanthin consumption with selected health benefits by performing a systematic review and meta-analysis.

    METHODS: Online literature search databases including Scopus, Web of Science, PubMed/Medline, Embase and Google Scholar were searched to discover relevant articles available up to 17 March 2020. We used mean changes and SD of the outcomes to assess treatment response from baseline and mean difference, and 95 % CI were calculated to combined data and assessment effect sizes in astaxanthin and control groups.

    RESULTS: 14 eligible articles were included in the final quantitative analysis. Current study revealed that astaxanthin consumption was not associated with FBS, HbA1c, TC, LDL-C, TG, BMI, BW, DBP, and SBP. We did observe an overall increase in HDL-C (WMD: 1.473 mg/dl, 95 % CI: 0.319-2.627, p = 0.012). As for the levels of CRP, only when astaxanthin was administered (i) for relatively long periods (≥ 12 weeks) (WMD: -0.528 mg/l, 95 % CI: -0.990 to -0.066), and (ii) at high dose (> 12 mg/day) (WMD: -0.389 mg/dl, 95 % CI: -0.596 to -0.183), the levels of CRP would decrease.

    CONCLUSION: In summary, our systematic review and meta-analysis revealed that astaxanthin consumption was associated with increase in HDL-C and decrease in CRP. Significant associations were not observed for other outcomes.
