Scalable policy adoption and sustainable implementation of surgical care in the Americas.

On September 29, 2023, the Republic of Ecuador convened a meeting to address surgical system strengthening and urge political leaders to invest in surgical infrastructure. The meeting included experts in health diplomacy, innovative financing, implementation strategy and national surgical plans. The event occurred in parallel with the Sixtieth Directing Council of the Pan American Health Organization, Seventy-fifth session of the World Health Organization Regional Committee for the Americas.

Building resilient surgical systems that can withstand external shocks.

When surgical systems fail, there is the major collateral impact on patients, society and economies. While short-term impact on patient outcomes during periods of high system stress is easy to measure, the long-term repercussions of global crises are harder to quantify and require modelling studies with inherent uncertainty. When external stressors such as high-threat infectious disease, forced migration or climate-change-related events occur, there is a resulting surge in healthcare demand.

A Cosmopolitan Argument for Temporary "Diagonal" Short-Term Surgical Missions as a Component of Surgical Systems Strengthening.

We propose an argument for “diagonal” short-term surgical missions as a stop-gap component of global surgical systems strengthening based upon the political justice theory of moral cosmopolitanism

An end-to-end deep learning pipeline to derive blood input with partial volume corrections for automated parametric brain PET mapping.

Dynamic 2-[18F] fluoro-2-deoxy-D-glucose positron emission tomography (dFDG-PET) for human brain imaging has considerable clinical potential, yet its utilization remains limited. A key challenge in the quantitative analysis of dFDG-PET is characterizing a patient-specific blood input function, traditionally reliant on invasive arterial blood sampling. This research introduces a novel approach employing non-invasive deep learning model-based computations from the internal carotid arteries (ICA) with partial volume (PV) corrections, thereby eliminating the need for invasive arterial sampling.

Social determinants of gastrointestinal malformation mortality in Brazil: a national study.

Introduction: In Brazil, approximately 5% are born with a congenital disorder, potentially fatal without surgery. This study aims to evaluate the relationship between gastrointestinal congenital malformation (GICM) mortality, health indicators, and socioeconomic factors in Brazil.

Methods: GICM admissions (Q39-Q45) between 2012 and 2019 were collected using national databases.
