Objectives:
This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition.The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach.
Methods:
A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and anti resorptive agents in sequential therapy approaches.
Results:
The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to anti resorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for in dividuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment.
Conclusions
This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.

Objectives:
The aim of this study was to characterize the benefits of converting Electronic Medical Records (EMRs) to a common data model (CDM) and to assess the potential of CDM-converted data to rapidly generate insights for benefit-risk assessments in post-market regulatory evaluation and decisions.
Methods:
EMRs from January 2013 to December 2016 were mapped onto the Observational Medical Outcomes Partnership-CDM (OMOP-CDM) schema. Vocabulary mappings were applied to convert source data values into OMOP-CDM-endorsed terminologies. Existing analytic codes used in a prior OMOP-CDM drug utilization study were modified to conduct an illustrative analysis of oral anticoagulants used for atrial fibrillation in Singapore and South Korea, resembling a typical benefit-risk assessment. A novel visualization is proposed to represent the comparative effectiveness, safety and utilization of the drugs.
Results:
Over 90% of records were mapped onto the OMOP-CDM. The CDM data structures and analytic code templates simplified the querying of data for the analysis. In total, 2,419 patients from Singapore and South Korea fulfilled the study criteria, the majority of whom were warfarin users. After 3 months of follow-up, differences in cumulative incidence of bleeding and thromboembolic events were observable via the proposed visualization, surfacing insights as to the agent of preference in a given clinical setting, which may meaningfully inform regulatory decision-making.
Conclusions
While the structure of the OMOP-CDM and its accessory tools facilitate real-world data analysis, extending them to fulfil regulatory analytic purposes in the post-market setting, such as benefit-risk assessments, may require layering on additional analytic tools and visualization techniques.

As one of the hallmarks of cancer, metabolic reprogramming leads to cancer progression, and targeting glycolytic enzymes could be useful strategies for cancer therapy. By screening a small molecule library consisting of 1320 FDA-approved drugs, we found that penfluridol, an antipsychotic drug used to treat schizophrenia, could inhibit glycolysis and induce apoptosis in esophageal squamous cell carcinoma (ESCC). Gene profiling and Ingenuity Pathway Analysis suggested the important role of AMPK in action mechanism of penfluridol. By using drug affinity responsive target stability (DARTS) technology and proteomics, we identified phosphofructokinase, liver type (PFKL), a key enzyme in glycolysis, as a direct target of penfluridol. Penfluridol could not exhibit its anticancer property in PFKL-deficient cancer cells, illustrating that PFKL is essential for the bioactivity of penfluridol. High PFKL expression is correlated with advanced stages and poor survival of ESCC patients, and silencing of PFKL significantly suppressed tumor growth. Mechanistically, direct binding of penfluridol and PFKL inhibits glucose consumption, lactate and ATP production, leads to nuclear translocation of FOXO3a and subsequent transcriptional activation of BIM in an AMPK-dependent manner. Taken together, PFKL is a potential prognostic biomarker and therapeutic target in ESCC, and penfluridol may be a new therapeutic option for management of this lethal disease.

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.

Objective: Mulberry (Morus spp.) fruits and leaves have been proven to possess nutraceutical properties. Due to its fast and easy growing characteristics, mulberry fruits (MF) and leaves (ML) potentially emerge as a great source of functional foods. This study aims to enhance bioactivities (antioxidant, anti-inflammation, and hypoglycemic activity) of MF and ML via submerged fermentation using bacteria (Lactobacillus plantarum TAR 4), yeast (Baker's yeast and red yeast) and fungi (Tempeh and Tapai starter). Methods: In this study, 25% (mass to volume ratio) of MF and ML were fermented (48 h) with 1% (mass to volume ratio) of different microbial cultures, respectively. Effects of different fermentations on MF and ML were determined based on the changes of total phenolics (TPC), flavonoids (TFC), anthocyanins, total sugar, DPPH activity, ferric reducing antioxidant power (FRAP), albumin denaturation inhibition activity (ADI), anti-lipoxygenase activity and α-amylase inhibition activity (AI). Results: Generally, ML had higher AI than MF. However, MF exhibited higher DPPH, FRAP and anti-lipoxygenase activity than ML. After all forms of fermentation, DPPH and AI activity of MF and ML were increased significantly (P < 0.05). However, the effects of fermentation on TPC, FRAP, ADI and anti-lipoxygenase activity of MF were in contrast with ML. TPC, FRAP and anti-lipoxygenase activity of ML were enhanced, but reduced in MF after fermentation. Although the effects exerted by different microorganisms in MF and ML fermentation were different, the bioactivities of MF and ML were generally improved after fermentation. Fermentation by Tempeh starter enhanced TPC (by 2-fold), FRAP (by 2.3-fold), AI (at 10% increment) and anti-lipoxygenase activity (by 5-fold) of ML, whereas Tapai fermentation effectively enhanced the DPPH (at 17% increment) and ADI (by 2-fold) activity of MF. Conclusion: Findings of this study provide an insight into the future process design of MF and ML processing into novel functional foods.

INTRODUCTION:
Polypharmacy and inappropriate prescribing are associated with negative health outcomes in the elderly. Several prescribing tools have been developed to assess medication appropriateness. Explicit (criteria-based) tools often do not take into account patients' preferences and comorbidities, and have little room for individualised clinical judgement.
METHODS:
A cross-sectional observational study was conducted in 243 elderly patients admitted to the Geriatric Medicine service in a Singapore tertiary hospital over one month. We incorporated an implicit (judgement-based) tool developed by Scott et al into a mnemonic, 'S-I-R-E', to assess medication appropriateness: S = symptoms ('Have symptoms resolved?'), I = indication ('Is there a valid indication?'), R = risks ('Do risks outweigh benefits?') and E = end of life ('Is there short life expectancy limiting clinical benefit?').
RESULTS:
Inappropriate prescribing was present in 27.6% of patients. The most common reason for inappropriateness of medications was lack of valid indication (62.2%), followed by high risk-benefit ratio (20.7%). The most common medications that lacked valid indication were supplements and proton pump inhibitors. Polypharmacy was found in 93% of patients and was significantly associated with inappropriate prescribing (p = 0.047).
CONCLUSION
Inappropriate prescribing and polpharmacy are highly prevalent in the hospitalised elderly. The 'S-I-R-E' mnemonic can be used as a memory aid and practical framework to guide appropriate prescribing in the elderly.

Introduction:
This study aims to describe the content of several pre-independence medical journals published in
British Malaya.
Methods:
The content of five journals were retrieved from National Library of Singapore e-resources and print collection of the Reference Library, Institute for Medical Research, Kuala Lumpur, Malaysia. The content of these journals was classified and descriptive analysis performed.
Results:
The five journals identified were Journal of the Straits Medical Association, Journal of the Malaya Branch of the British Medical Association, Malaya Medical Journal, Malayan Medical Journal and Journal of the Malaya Branch of the British Medical Association (new series). A total of 81 issues with 873 articles were retrieved. Almost one-third of articles were concerned with these topics: malaria, mosquito control, beri-beri, tuberculosis, sexually transmitted diseases, helminthiasis, leprosy and cholera. One-fifth of the articles were case reports and 95% of the articles were written by single authors.
Discussion
The content of these journals is a good resource for those who are interested in the history of medicine – it provided substantial details on the state of public health and chronicled the medical writings of medical workers in British Malaya. It illustrates well the introduction of Western medicine to tackle health problems that arose from the interplay of immigration, poor environmental sanitation and economic exploitation.

OBJECTIVETo observe the effects of Qiangjing Tablets (QJT) on the semen quality and Fas/FasL signaling pathway in male SD rats with infertility.
METHODSModels of infertility were made in 50 male SD rats by intragastric administration of Tripterygium (GTW) for 3 weeks, and another 20 rats were taken as blank controls. Then 40 successfully established rat models were randomly divided into four groups, model control, low-dose QJT, medium-dose QJT, and high-dose QJT, the latter three groups treated intragastrically with QJT at 58 mg, 105 mg, and 233 mg per kg of the body weight per day, respectively. After 4 weeks of medication, the rats were killed for examination of semen quality and determination of the expression of the apoptosis factor FasL in the testis tissue.
RESULTSCompared with the blank controls, the model rats showed significant decreases in sperm concentration ([71.99 ± 9.72] vs [10.94 ± 3.58] x 10⁶/ml, P < 0.01), motility ([48.95 ± 4.10] vs [9.31 ± 5.79]%, P < 0.01), and viability ( [82.06 ± 6.16] vs [24.03 ± 6.93]%, P < 0.01). In comparison with the model controls, the rats in the QJT groups exhibited remarkably increased sperm concentration, motility, and viability, more significantly in the high-dose group ([59.66 ± 4.53] x 10⁶/ml, [35.45 ± 5.21] %, and [61.97 ± 9.75]%) and medium-dose group ([40.89 ± 4.90] x 10⁶/ml, [24.41 ± 4.79]%, and [60.06 ± 10.62]%) (P < 0.05 or P < 0.01). The expression of FasL was markedly reduced in the low-, medium-, and high-dose QJT groups (0.5215 ± 0.0189, 0.5371 ± 0.0364, and 0.4556 ± 0.0215) as compared with that of the model controls (0.5989 ± 0.0448 ) (P < 0.05 or P < 0.01).
CONCLUSIONBy upregulating the Fas/FasL signaling pathway, Tripterygium glycosides may induce the apoptosis of spermatogenic cells and reduce sperm concentration, motility and viability, resulting in infertility. The Chinese medicine Qiangjing Tablets can improve the reproductive function of male rats by decreasing the expression of the apoptosis factor FasL in the testis.
