Background: The health system's capacity to store vaccines in North Korea has been less studied. In this study, we aimed to investigate if the current vaccine cold chain in North Korea can store routine vaccines and if it has the storage capacity to handle pandemic vaccination activities (PVAs) without interrupting the country’s successful routine immunization program. Methods: We used tables extracted from an evaluation report of The Global Alliance for Vaccines and Immunization (GAVI)’ Health Systems Strengthening program in North Korea from 2007 to 2014. We then used the World Health Organization’s Immunization Supply Chain Sizing Tool to estimate gaps and the cost of scaling up cold chain storage. Results: We found that the vaccine cold chain in North Korea has adequate storage capacity for routine vaccines. While we found a deficit of 7,172 L at the central medical warehouse (CMW) and 14,256 L at the provincial medical warehouses (PMWs), the storage at the county warehouses (CoMW) had a surplus. When assessed for PVA, we found an aggregated deficit of 115,574 L (CMW), 113,160 L (PMW), and 25,133 L (CoMW). To fill the gaps, investments of 229,917 USD, and 2,262,211 USD were estimated for routine and PVA vaccination programs, respectively. Conclusion As countries and the international community work to improve systems in preparation for future pandemics, there is a need to scale up the North Korean vaccine cold chain to a pandemic-ready state.

INTRODUCTION: Trastuzumab deruxtecan (T-DXd) has revolutionised treatment for metastatic breast cancer (MBC). While effective, its high cost and toxicities, such as fatigue and nausea, pose challenges. METHOD: Medical records from the Joint Breast Cancer Registry in Singapore were used to study MBC patients treated with T-DXd (February 2021-June 2024). This study was conducted to address whether reducing dose intensity and density may have an adverse effect on treatment outcomes. RESULTS: Eighty-seven MBC patients were treated with T-DXd, with a median age of 59 years. At the time of data cutoff, 32.1% of patients were still receiving T-DXd. Over half (54%) of the patients received treatment with an initial relative dose intensity (RDI) of <;85%. Overall median real-world progression-free survival (rwPFS) was 8.1 months. rwPFS was similar between RDI groups (<85%: 8.7 months, <85%: 8.1 months, P=0.62). However, human epidermal growth receptor 2 (HER2)-positive patients showed significantly better rwPFS outcomes compared to HER2-low patients (8.8 versus 2.5 months, P<0.001). Only 16% with central nervous system (CNS) involvement had CNS progressive disease on treatment. No significant progression-free survival (PFS) differences were found between patients with or without CNS disease, regardless of RDI groups. Five patients (5.7%) developed interstitial lung disease (ILD), with 3 (3.4%) having grade 3 events. Two required high-dose steroids and none were rechallenged after ILD. There were no fatalities. CONCLUSION Our study demonstrated that reduced dose intensity and density had no significant impact on rwPFS or treatment-related toxicities. Furthermore, only 5.7% of patients developed ILD. T-Dxd provided good control of CNS disease, with 82% of patients achieving CNS disease control.

INTRODUCTION: Obstructive sleep apnoea (OSA) is common in Singapore, with moderate to severe OSA affecting around 30% of residents. These consensus statements aim to provide scientifically grounded recommendations for the management of OSA, standar-dise the management of OSA in Singapore and promote multidisciplinary collaboration. METHOD: An expert panel, which was convened in 2024, identified several areas of OSA management that require guidance. The expert panel reviewed the current literature and developed consensus statements, which were later independently voted on using a 3-point Likert scale (agree, neutral or disagree). Consensus (total ratings of agree and neutral) was set a priori at ≥80% agreement. Any statement not reaching consensus was excluded. RESULTS: The final consensus included 49 statements that provide guidance on the screening, diagnosis and management of adults with OSA. Additionally, 23 statements on the screening, diagnosis and management of paediatric OSA achieved consensus. These 72 consensus statements considered not only the latest clinical evidence but also the benefits and harms, resource implications, feasibility, acceptability and equity impact of the recommendations. CONCLUSION The statements presented in this paper aim to guide clinicians based on the most updated evidence and collective expert opinion from sleep specialists in Singapore. These recommendations should augment clinical judgement rather than replace it. Management decisions should be individualised, taking into account the patient's clinical characteristics, as well as patient and caregiver concerns and preferences.

Background: The association between happiness and suicide behaviour across different gender and age groups remains unclear, with few studies identifying potential confounding or mediating factors that explain this association. We aimed 1) to examine the association of happiness with suicide ideation/attempt and 2) to assess the relative contribution of potential factors in explaining the associations in South Korea. Methods: We used data from the Korea Community Health Survey 2021, with 214,070 respondents aged over 20 years. Happiness was measured by using Cantril’s ladder of life satisfaction. Suicide ideation and suicide attempt were each measured by a single question.A hierarchical logistic regression model was used to identify the association between happiness and suicide ideation/attempt and estimate the relative importance of each socioenvironmental, psychological, and health-related factor. Results: Unhappiness was associated with suicide ideation/attempt across gender and age groups. The associations appeared stronger in younger rather than older adults, particularly for women aged 20–39 and 40–59 years. Psychological factors contributed the most to explaining the association across all genders and age groups. Socio-environmental factors explained the associations more among individuals aged 40–59 years and health-related factors were more pronounced in explaining the association among those aged 60 years and above, compared to other age groups. Conclusion Unhappiness is associated with suicide ideation/attempt. Psychological factors could largely explain this association, suggesting that improving population mental health could play an important role in increasing happiness and preventing suicide behaviour.
