Exploring Determinants of Community Flood Resilience in Southeast Asia: A Systematic Review

Flooding is the most devastating natural disaster in Southeast Asia, disproportionately affecting vulnerable communities and posing substantial public health challenges. This PRISMA 2020 systematic review, registered with PROSPERO, aimed to synthesize the determinants influencing...

The economic impact of COVID-19: losses and resilience factors

This study proposes a numerical assessment of the economic loss associated with COVID-19 across 46 countries. We estimate these losses by forecasting each country’s counterfactual GDP, that is, the GDP that would have occurred in the absence of the pandemic, using a hybrid WT–QPS...

Correlations between baseline anatomy, respiratory motion, and cardiac dose in DIBH breast radiotherapy

Abstract Purpose: Deep inspiration breath-hold (DIBH) is widely used to reduce cardiac dose in breast radiotherapy; however, its dosimetric benefit has not been well characterized at the individual patient level. This study aimed to evaluate the relationships between anatomical p...

Assessment of left atrial native T1 values using non-contrast 3.0 T cardiac magnetic resonance imaging: a feasibility and reproducibility study

Atrial cardiomyopathy (ATC) is characterized by structural and functional atrial remodeling and is associated with adverse cardiovascular outcomes. Native T1 mapping has emerged as a sensitive technique for tissue characterization; however, data on left atrial (LA) native T1 mapp...

Comparison of TG-43 and advanced collapsed cone engine dose calculations in cervical HDR brachytherapy with plastic and metallic applicators

Abstract Purpose: Conventional brachytherapy treatment planning based on the TG-43 formalism assumes a homogeneous water medium and neglects the effects of applicator materials and tissue heterogeneities. This study aimed to investigate the clinical impact of Model-Based Dose Cal...

Quantitative verification of treatment delivery accuracy utilizing deep inspiration breath hold (DIBH) for left-sided breast irradiation

Abstract Purpose: To assess the treatment delivery accuracy of left-sided breast irradiation using the deep inspiration breath hold (DIBH) technique via Gamma passing rate (GPR) analysis. Methods: Thirteen patients with left-sided breast cancer who had previously undergone volume...
