Today is World Prematurity Day 2025 — an important reminder of the ongoing challenge posed by preterm birth, particularly in twin pregnancies.

Over 50% of twins are born prematurely, with a significantly higher risk of neonatal morbidity and mortality compared to singletons. These early births are often the result of spontaneous preterm labour or medically indicated delivery due to complications such as selective growth restriction.

Twin pregnancies require tailored surveillance and proactive management. As clinicians, we must continue to:
🔹 Recognise and stratify risk early
🔹 Optimise antenatal monitoring
🔹 Plan timing and mode of delivery based on the best available evidence

Improving outcomes for twins born too soon is possible — but it demands collaboration, expertise, and continued research.

Rethinking Stroke Rehabilitation: Why Traditional Recovery Goals Are No Longer Enough

As we mark World Stroke Day, the Singapore Medical Journal's October Editorial by Jack Lo Yu Tung, Benjamin YQ Tan and Ramani, Narayanaswamy Venketasubramanian tackles an urgent reality: stroke is increasingly affecting younger adults, challenging traditional assumptions about who it impacts.

The Changing Face of Stroke in Singapore:
1) Nearly 1 in 3 of the 9,700 annual stroke cases occur in people under 60.
2) Stroke cases have risen by over 50% from 2012 to 2022.
3) >15% of all strokes now affect individuals under 50.
4) For younger, digitally-native survivors navigating careers and complex social lives, achieving "independent walking" or "basic activities of daily living" is no longer sufficient for meaningful reintegration into modern society.

Enter the Technological Revolution:
Brain-computer interfaces (BCIs) and neurorehabilitative technologies are transforming what's possible. By decoding motor intention directly from cortical neurons, BCIs can bypass damaged neural circuitry—translating thoughts into action through:
1) Robotic limbs
2) Functional electrical stimulation
3) Virtual reality platforms
4) Even wheelchair control for severe cases

This isn't just biomechanical restoration—it's the re-establishment of cognitive agency.

The Path Forward:
While early evidence is encouraging (meta-analyses show BCI-guided therapy enhances upper limb function beyond conventional therapy), challenges remain: cost, accessibility, scalability, and the need for clinical workflow integration.

But the possibilities are vast. As Singapore becomes a super-aged society by 2026, it's time for clinicians, researchers, and policymakers to reimagine functional restoration in stroke care.

After all, the mind is our greatest untapped resource in neurological recovery.

👁️‍🗨️ Visual Impairment and Obesity in Rural China

A study of over 39,000 students in rural northwest China reveals a significant association between visual impairment (VI) and obesity in school-age children.

📍 Key findings:
📊 1 in 3 students had visual impairment
⚖️ Obesity was linked to higher odds of VI, especially among:
🧒 Primary school students
🧬 Han students
📍 Residents of Ningxia

⚠️ The findings highlight the dual burden of VI and obesity in underserved rural areas, pointing to the need for integrated school-based interventions — promoting both healthy vision and active lifestyles.

A comprehensive panel of experts from all three government hospitals in Singapore 🇸🇬 (KK Women's and Children's Hospital, Singapore General Hospital, National University Hospital), together with experts from National University of Singapore and Cincinnati Children's Hospital 🇺🇸, have developed a consensus statement and recommendations as to how we administer antenatal steroids. This rigorous statement draws on human clinical data, experimental studies, and computational modeling. 🔬📊

The consensus article suggests that adopting internationally validated antenatal steroid regimens could improve outcomes while potentially reducing risks. ✅ This represents an important step toward aligning Singapore's practices with global evidence-based standards in preterm care. 🌍

Published in the Singapore Medical Journal 📖, this article provides detailed pharmacokinetic analysis and comprehensive recommendations for clinical practice. This collaborative effort demonstrates Singapore's commitment to continuously improving perinatal care through rigorous scientific evaluation.

Read the full consensus statement to learn about the specific dosing recommendations, the scientific evidence behind them, and how this change could benefit preterm infants and their families. 👨‍👩‍👧‍👦💙

Clinical profile and outcomes in patients with moderate to severe aortic stenosis with or without concomitant chronic kidney disease

🩺 When heart and kidney disease collide
In this study of 727 patients with moderate to severe aortic stenosis (AS), coexisting chronic kidney disease (CKD) was linked to higher mortality, more heart failure admissions, and lower rates of valve replacement—despite similar AS severity. CKD patients also showed signs of adverse cardiac remodeling, suggesting an independent role of CKD in worsening outcomes. The findings highlight a critical treatment gap and underscore the need for tailored approaches, including earlier consideration of transcatheter valve therapy in high-risk patients.

👏 Congratulations to Dr Ngiam, Dr @chinghuisia and the entire research team on this important work advancing care in complex cardio-renal disease.

🫀 What do we know about heart failure with mildly reduced ejection fraction (HFmrEF) — particularly in Asian populations?

This large-scale national study of over 16,000 patients reveals that HFmrEF is a unique clinical phenotype, carrying an atherosclerotic burden and mortality risk between HFrEF and HFpEF. The findings underscore the need for targeted strategies to manage this under-recognised subgroup of heart failure.

👏 Congratulations to Dr Tay, @Jonyap88 et al. for this impactful contribution to cardiovascular medicine research.
