To evaluate outcome trends of neonates born very preterm in 11 high-income countries participating in the International Network for Evaluating Outcomes of neonates.
In a retrospective cohort study, ...we included 154 233 neonates admitted to 529 neonatal units between January 1, 2007, and December 31, 2015, at 240/7 to 316/7 weeks of gestational age and birth weight <1500 g. Composite outcomes were in-hospital mortality or any of severe neurologic injury, treated retinopathy of prematurity, and bronchopulmonary dysplasia (BPD); and same composite outcome excluding BPD. Secondary outcomes were mortality and individual morbidities. For each country, annual outcome trends and adjusted relative risks comparing epoch 2 (2012-2015) to epoch 1 (2007-2011) were analyzed.
For composite outcome including BPD, the trend decreased in Canada and Israel but increased in Australia and New Zealand, Japan, Spain, Sweden, and the United Kingdom. For composite outcome excluding BPD, the trend decreased in all countries except Spain, Sweden, Tuscany, and the United Kingdom. The risk of composite outcome was lower in epoch 2 than epoch 1 in Canada (adjusted relative risks 0.78; 95% CI 0.74-0.82) only. The risk of composite outcome excluding BPD was significantly lower in epoch 2 compared with epoch 1 in Australia and New Zealand, Canada, Finland, Japan, and Switzerland. Mortality rates reduced in most countries in epoch 2. BPD rates increased significantly in all countries except Canada, Israel, Finland, and Tuscany.
In most countries, mortality decreased whereas BPD increased for neonates born very preterm.
Resumen:
La soberanía alimentaria es el derecho colectivo a decidir sobre la producción, distribución y consumo de alimentos y promueve la generación de suministros alimenticios para el consumo local ...de tal forma que los consumidores queden resguardados de la volatilidad de los precios de mercados internacionales. En los pueblos indígenas esta tendencia resulta trascendental para hacer frente a condiciones de inequidad histórica que han impactado negativamente su salud pública. No obstante, es ignorada en algunos casos y en otros reemplazada por nociones centradas en la seguridad alimentaria, término alineado con políticas transnacionales derivadas del modelo económico dominante.
Objetivo:
analizar con tres comunidades indígenas de Colombia las perspectivas de soberanía alimentaria y su influencia en la salud.
Método:
investigación participativa basada en la comunidad, para recolectar datos mediante grupos de discusión, entrevistas y observación. La población de estudio fueron tres comunidades indígenas del sur de Colombia. La selección de participantes se realizó según su trayectoria en la comunidad.
Resultados:
las comunidades entienden la soberanía alimentaria como la conservación de semillas nativas y alimentos propios, vista como oportunidad para el cuidado de la salud. Su debilitamiento se relaciona con el desarrollo de enfermedades de las personas y de la madre tierra. Para su fortalecimiento identificaron el tul, el yatul y la chagra (huerta) que reafirman la unión familiar, contribuyen a la recuperación de modos de producción desde la sabiduría ancestral y se posicionan como alternativa para la sostenibilidad económica.
Conclusión:
la soberanía alimentaria conserva los saberes y prácticas tradicionales para una alimentación propia, debilitada por los sistemas agroindustriales. Es asumida como iniciativa local suscrita en un proyecto global de resistencia política y económica para la salud colectiva de los pueblos.
A rare clinical observation of death from prolonged uneven external irradiation due to the deliberate use of an ionizing radiation source for illegal purposes has been presented. The main ...difficulties of postmortem diagnosis of this type of radiation-induced injury, considering the features of histological examinations and special methods of retrospective dosimetric evaluations, have been identified.

Meningiomas are the most frequent primary intracranial tumors. Patient outcome varies widely from benign to highly aggressive, ultimately fatal courses. Reliable identification of risk of progression ...for individual patients is of pivotal importance. However, only biomarkers for highly aggressive tumors are established (
and
), whereas no molecularly based stratification exists for the broad spectrum of patients with low- and intermediate-risk meningioma.
DNA methylation data and copy-number information were generated for 3,031 meningiomas (2,868 patients), and mutation data for 858 samples. DNA methylation subgroups, copy-number variations (CNVs), mutations, and WHO grading were analyzed. Prediction power for outcome was assessed in a retrospective cohort of 514 patients, validated on a retrospective cohort of 184, and on a prospective cohort of 287 multicenter cases.
Both CNV- and methylation family-based subgrouping independently resulted in increased prediction accuracy of risk of recurrence compared with the WHO classification (c-indexes WHO 2016, CNV, and methylation family 0.699, 0.706, and 0.721, respectively). Merging all risk stratification approaches into an integrated molecular-morphologic score resulted in further substantial increase in accuracy (c-index 0.744). This integrated score consistently provided superior accuracy in all three cohorts, significantly outperforming WHO grading (c-index difference
= .005). Besides the overall stratification advantage, the integrated score separates more precisely for risk of progression at the diagnostically challenging interface of WHO grade 1 and grade 2 tumors (hazard ratio 4.34 2.48-7.57 and 3.34 1.28-8.72 retrospective and prospective validation cohorts, respectively).
Merging these layers of histologic and molecular data into an integrated, three-tiered score significantly improves the precision in meningioma stratification. Implementation into diagnostic routine informs clinical decision making for patients with meningioma on the basis of robust outcome prediction.
