Purpose: This study aimed to compare cognitive, non-cognitive, and overall learning outcomes for sepsis and trauma resuscitation skills in novices with virtual patient simulation (VPS) versus in-person simulation (IPS). Methods: A randomized controlled trial was conducted on junior doctors in 1 emergency department from January to December 2022, comparing 70 minutes of VPS (n=19) versus IPS (n=21) in sepsis and trauma resuscitation. Using the nominal group technique, we created skills assessment checklists and determined Bloom’s taxonomy domains for each checklist item. Two blinded raters observed participants leading 1 sepsis and 1 trauma resuscitation simulation. Satisfaction was measured using the Student Satisfaction with Learning Scale (SSLS). The SSLS and checklist scores were analyzed using the Wilcoxon rank sum test and 2-tailed t-test respectively. Results: For sepsis, there was no significant difference between VPS and IPS in overall scores (2.0; 95% confidence interval [CI], -1.4 to 5.4; Cohen’s d=0.38), as well as in items that were cognitive (1.1; 95% CI, -1.5 to 3.7) and not only cognitive (0.9; 95% CI, -0.4 to 2.2). Likewise, for trauma, there was no significant difference in overall scores (-0.9; 95% CI, -4.1 to 2.3; Cohen’s d=0.19), as well as in items that were cognitive (-0.3; 95% CI, -2.8 to 2.1) and not only cognitive (-0.6; 95% CI, -2.4 to 1.3). The median SSLS scores were lower with VPS than with IPS (-3.0; 95% CI, -1.0 to -5.0). Conclusion For novices, there were no major differences in overall and non-cognitive learning outcomes for sepsis and trauma resuscitation between VPS and IPS. Learners were more satisfied with IPS than with VPS (clinicaltrials.gov identifier: NCT05201950).

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.

Night-shift work may adversely affect health. This study aimed to assess the effect of night-shift work on the level of urinary 6-sulphatoxymelatonin. Repeated measures of urinary 6-sulphatoxymelatonin on the morning before night-shift work and after first, third and fifth night-shift work was undertaken in 29 males, Malay, day-night-shift workers. A total of 29 male workers participated in this study. Median age was 29 years old. The highest level of urinary 6-sulphatoxymelatonin was at time point 1, followed by a significant reduction from time point 1 to time point 2. Subsequently, there was a progressive increase of urinary 6-sulphatoxymelatonin from time point 2 to 4. However, the urinary 6-sulphatoxymelatonin did not normalise at time point 4 and remained lower than the baseline

Duration after Macular Hole Surgery for Stabilisation of Visual Acuity: A Long-term Retrospective Review The purpose of the study is to determine the median duration for visual recovery to achieve visual stability and visual acuity gain after macular hole surgery in our local population. This was a retrospective study. Patients with full-thickness macular holes (FTMH) from surgical logs were included between January 2009 and December 2019. The patients' medical records were reviewed for pre-, intra-, and post-operative data collection. Patients who fulfilled the inclusion and exclusion criteria were recruited and analysed. Data collected from the medical record pre-operatively, which included baseline best corrected visual acuity (BCVA), interval of symptoms development to surgery, any ocular co-morbidities, optical coherence tomography (OCT) for size and stage of macular hole and central subfield thickness (CST). Intra-operative notes included whether vitrectomy with or without phacoemulsification and with the internal limiting membrane (ILM) peel or ILM flaps, types of dye, and tamponade agent used. Post-operative data included BCVA and CST on each visit, types of macular hole closure, or any complications. Data were analysed using SPSS.Thirty-one patients were diagnosed with FTMH. Sixteen patients who underwent pars plana vitrectomy (PPV) were included and analysed. Fifteen patients (93.75%) achieved successful macular hole closure after the primary operation. The median duration BCVA reached at stability was 19.5 months (IQR 9 – 26.25), and visual acuity gained by 0.44 LogMAR (IQR 0.165 – 0.565). Ten patients (62.5%) underwent combined PPV with phacoemulsification. CST showed improvement from baseline, 444 (IQR 347.5 – 519.75) to 273 (IQR 232 -285.5), 230 (IQR 221.5-255), and 270 (IQR 254-322) at the period interval of 0 to 3 months, 3 to 6 months, and 6 to 12 months respectively. Gas C3F8 and membrane blue were commonly used as tamponade agents and dyes, and PPV with ILM peel was the common surgery performed. Six patients (40%) achieved type 1 macular hole closure within 12 months of follow-up. Despite the small sample size, our study provided practical information regarding patient’s expectations of when their vision can become stable after macula hole surgery in our local population.

Cyclin-dependent kinase 9 (CDK9) activity is correlated with worse outcomes of triple-negative breast cancer (TNBC) patients. The heterodimer between CDK9 with cyclin T1 is essential for maintaining the active state of the kinase and targeting this protein-protein interaction (PPI) may offer promising avenues for selective CDK9 inhibition. Herein, we designed and generated a library of metal complexes bearing the 7-chloro-2-phenylquinoline CˆN ligand and tested their activity against the CDK9-cyclin T1 PPI. Complex 1 bound to CDK9 via an enthalpically-driven binding mode, leading to disruption of the CDK9-cyclin T1 interaction in vitro and in cellulo. Importantly, complex 1 showed promising anti-metastatic activity against TNBC allografts in mice and was comparably active compared to cisplatin. To our knowledge, 1 is the first CDK9-cyclin T1 PPI inhibitor with anti-metastatic activity against TNBC. Complex 1 could serve as a new platform for the future design of more efficacious kinase inhibitors against cancer, including TNBC.

Aortoiliac occlusive disease (AIOD) refers to the stenosis and occlusion of the distal abdominal aorta and(or) bifurcation of the aortoiliac artery,which is mainly caused by atherosclerosis,leading to pelvic and lower limb ischemia.Open surgery has always been the main treatment for complex AIOD.However,in recent years,with the development of endovascular surgery technologies and medical instruments,its treatment concept has been greatly changed.More and more clinical evidence has proved that the long-term efficacy of endovascular therapy is not inferior to that of traditional open surgery,so minimally invasive endovascular therapy has become the preferred treatment for AIOD.
