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.

Purpose: Although adjuvant chemotherapy (CTx) is still recommended for high-risk patients with hormone receptorpositive and human epidermal receptor (HER)-2-negative breast cancer, recent studies found that selected patients with low disease burden may be spared from CTx and receive hormonal treatment (HT) alone. This study aims to evaluate the trends of treatment (CTx + HT vs. HT alone) in Korea and to assess the impact on overall survival (OS) according to treatment pattern. Methods: The Korean Breast Cancer Society Registry was queried (2000 to 2018) for women with pT1-2N0-1 hormone receptor-positive and HER2-negative disease who underwent surgery and adjuvant systemic treatment (CTx and HT). Clinicopathologic factors, change in pattern of treatment over time, and OS for each treatment option were analyzed. Results: A total of 40,938 women were included in the study; 20,880 (51.0%) received CTx + HT, while 20,058 (49.0%) received HT only. In recent years, there has been a steady increase in the use of HT alone, from 21.0% (2000) to 64.6% (2018). In Cox regression analysis, age, type of breast and axillary operations, T and N stages, body mass index, histologic grade,and presence of lymphovascular invasion were prognostic indicators for OS. There was no significant difference between CTx + HT and HT alone in terms of OS (P = 0.126). Conclusion Over the years, there has been a shift from CTx + HT to HT alone without a significant difference in OS. Therefore, HT alone could be a safe treatment option in selected patients, even those with T2N1 disease.

Objective: To investigate the clinical factors associated with successful gastrostomy tube weaning in patients with prolonged dysphagia after stroke. Methods: This study involved a retrospective medical chart review of patients diagnosed with prolonged dysphagia after stroke who underwent gastrostomy tube insertion between May 2013 and January 2020. Forty-seven patients were enrolled and consequently divided into gastrostomy tube sustaining and weaning groups. The numbers of patients in the sustaining and weaning groups were 31 and 16, respectively. The patients’ demographic data, Korean version of Mini-Mental State Examination (K-MMSE) score, Korean version of the Modified Barthel Index (K-MBI), Functional Dysphagia Scale (FDS) score, and Penetration-Aspiration Scale (PAS) score were compared between the two groups. A videofluoroscopic swallowing study was performed before making the decision of gastrostomy tube weaning. The clinical factors associated with gastrostomy tube weaning were then investigated. Results: There were significant differences in age; history of aspiration pneumonia; K-MMSE, FDS, and PAS scores; and K-MBI between the groups. In the multiple logistic regression analysis, the FDS (odds ratio [OR]=0.791; 95% confidence interval [CI], 0.634–0.987) and PAS scores (OR=0.205; 95% CI, 0.059–0.718) were associated with successful gastrostomy tube weaning. In the receiver operating characteristic curve analysis, the FDS and PAS were useful screening tools for successful weaning, with areas under the curve of 0.911 and 0.918, respectively. Conclusion In patients with prolonged dysphagia, the FDS and PAS scores are the only factors associated with successful gastrostomy tube weaning. An evaluation of the swallowing function is necessary before deciding to initiate gastrostomy tube weaning.

Objective: We investigated the usefulness of maximal expiratory pressure (MEP) in evaluating dysphagia subsequent to ischemic stroke. Methods: This study included patients with ischemic stroke who underwent MEP testing and videofluoroscopic swallowing study (VFSS), from October 2016 to February 2020. The VFSS findings were interpreted using the penetrationaspiration scale (PAS) and functional dysphagia scale (FDS). Patients were stratified into the non-aspiration (n=59) and aspiration (n=47) groups. Partial correlation analysis among MEP, PAS, and FDS was performed after adjusting for age. Binary logistic regression using PAS was conducted to investigate the risk factors predisposing patients to inclusion in the aspiration group. Multiple linear regression using FDS was conducted to investigate the risk factors according to dysphagia severity. Receiver operating characteristic (ROC) curve analysis was applied to investigate factors which could be useful for detecting aspiration. Results: Student’s t-test revealed a significant difference in MEP between the non-aspiration and aspiration groups.MEP showed a positive correlation with PAS and FDS. MEP was also determined to be a risk factor for inclusion into the aspiration group, and a risk factor according to the severity of dysphagia. In the ROC curve analysis, MEP showed good diagnostic properties to help classify patients with aspiration. Conclusion Our results indicate that swallowing assessment can predict and help prevent aspiration pneumonia in patients with ischemic stroke. In the present study, MEP showed significant association with aspiration and the severity of dysphagia. Thus, determining the MEP during swallowing assessment in patients with ischemic stroke is potentially a useful parameter to predict dysphagia.

Objectives: To investigate the relationship between the psoas muscle cross-sectional area and physical performance in patients with liver cirrhosis. Methods: This study analyzed ambulatory patients with liver cirrhosis aged < 65 years, who underwent abdominal computed tomography (CT) and Short Physical Performance Battery (SPPB) tests from December 2018 to December 2019.A total of 46 patients (36 men, 10 women) were included. In abdominal CT scans, the psoas muscle cross-sectional area (mm2 ) was measured at the distal end-plate level of the L4 vertebral body and normalized by dividing by height (m).Physical performance was evaluated using SPPB. A correlation analysis between the psoas muscle cross-sectional area and SPPB was performed. Kruskal-Wallis test was used to determine differences in the psoas muscle cross-sectional area and SPPB according to the Child-Pugh classification. Multiple regression analysis was performed to determine factors affecting SPPB. Results: The correlation coefficient between the psoas muscle cross-sectional area and SPPB was 0.459 at the P < 0.01 level. No difference was observed in the psoas muscle cross-sectional area and SPPB according to the Child-Pugh classification. The psoas muscle cross-sectional area was a factor affecting SPPB in multiple regression analysis. Conclusions Abdominal CT is an essential diagnostic tool in patients with liver cirrhosis. Ambulatory patients with liver cirrhosis aged < 65 years could have reduced physical performance. In this study, the psoas muscle cross-sectional area was correlated with physical performance and was a factor affecting physical performance. The psoas muscle cross-sectional area and physical performance should be evaluated in patients with liver cirrhosis.

BACKGROUND AND OBJECTIVES: There is a paucity of data regarding the benefit of clopidogrel monotherapy after dual antiplatelet therapy (DAPT) in patients treated with drug-eluting stents (DES). This study compared outcome between clopidogrel versus aspirin as monotherapy after DES for acute myocardial infarction (MI). METHODS: From Korea Acute Myocardial Infarction Registry-National Institute of Health database, 1,819 patients treated with DES who were switched to monotherapy with clopidogrel (n=534) or aspirin (n=1,285) after uneventful 12-month DAPT were analyzed. The primary endpoint was net adverse clinical events (NACE), defined as a composite of death from any cause, MI, repeat percutaneous coronary intervention (PCI), stent thrombosis, ischemic stroke, or major bleeding during the period from 12 to 24 months. RESULTS: After adjustment using inverse probability of treatment weighting, patients who received clopidogrel, compared with those treated with aspirin, had a similar incidence of NACE (0.7% and 0.7%; hazard ratio, 1.06; 95% confidence interval, 0.31–3.60; p=0.923). The 2 groups had similar rates of death from any cause (0.1% in each group, p=0.789), MI (0.3% and 0.1%, respectively; p=0.226), repeat PCI (0.1% and 0.3%, respectively; p=0.548), stent thrombosis (0.1% and 0%, respectively; p=0.121), major bleeding (0.2% in each group, p=0.974), and major adverse cardiovascular and cerebrovascular events (0.5% in each group, p=0.924). CONCLUSIONS Monotherapy with clopidogrel, compared to aspirin, after DAPT showed similar clinical outcomes in patients with acute MI treated with DES.

Objective: The emergency medical service (EMS) is expected to improve the prognosis of patients suffering from acutemyocardial infarction (AMI). We investigated the impact of utilizing EMS on the clinical outcomes of AMI patients. Methods: From November 2011 to November 2015, a total of 13,102 patients in the Korea Acute Myocardial InfarctionRegistry-National Institute of Health (KAMIR-NIH) registry were enrolled. Patients were divided into two groups: the EMSgroup, first medical contact (FMC) with 119; the non-EMS group, the FMC at local hospitals that were not available forpercutaneous coronary intervention. The authors analyzed the mortality and major adverse cardiac and cerebrovascularevents during one-year of clinical follow-up. Results: A total of 8,863 patients were finally analyzed for this study, and a total of 1,999 patients (22.6%) utilized theEMS as FMC. The patients utilizing EMS were more frequently diagnosed with ST-segment elevation AMI. At presentation,the EMS group had a higher incidence of Killip class IV, and they had a shorter symptom-to-door time than non-EMS group. The patients utilizing EMS had higher incidence of peri-procedural complications and in-hospital mortality.The multivariate logistic regression analysis with backward elimination revealed that utilizing EMS is an independent factorfor predicting lower one-year mortality. Conclusion This study has demonstrated that the high-risk AMI patients can utilize the EMS in Korea. The EMS grouphas more favorable clinical outcome during one-year follow-up after discharge than the non-EMS group, whereas it had ahigher rate of death during hospitalization compared with that of the non-EMS group.

OBJECTIVE: To find out whether levels of fibrin degradation products (FDP) and D-dimer are increased in breast cancer-related lymphedema (BCRL) as in many vascular diseases. FDP and D-dimer have been used in blood tests to help differentiate deep vein thrombosis in the diagnosis of lymphedema. Levels of FDP and D-dimer are often elevated in patients with BCRL. METHODS: Patients with BCRL (group I), non-lymphedema after breast cancer treatment (group II), and deep venous thrombosis (group III) from January 2012 to December 2016 were enrolled. Levels of FDP and D-dimer were measured in all groups and compared among groups. RESULTS: Mean values of FDP and D-dimer of group I were 5.614±12.387 and 1.179±2.408 μg/μL, respectively. These were significantly higher than their upper normal limits set in our institution. Levels of FDP or D-dimer were not significantly different between group I and group II. However, values of FDP and D-dimer in group III were significantly higher than those in group I. CONCLUSION: Values of FDP and D-dimer were much higher in patients with thrombotic disease than those in patients with lymphedema. Thus, FDP and D-dimer can be used to differentiate between DVT and lymphedema. However, elevated levels of FDP or D-dimer cannot indicate the occurrence of lymphedema.
