Abstract Background The work of the WHO Commission on the Social Determinants of Health has been fundamental to provide a conceptual framework of the social determinants of health. Based on this framework, this study assesses the relationship of income inequality as a determinant of neonatal mortality in the Americas and relates it to the achievement of the Sustainable Development Goal target 3.2 (reduce neonatal mortality to at least as low as 12 deaths per 1,000 live births). The rationale is to evaluate if income inequality may be considered a social factor that influences neonatal mortality in the Americas. Methods Yearly data from 35 countries in the Americas during 2000–2019 was collected. Data sources include the United Nations Inter-agency Group for Child Mortality Estimation for the neonatal mortality rate (measured as neonatal deaths per 1,000 live births) and the United Nations University World Institute for Development Economics Research for the Gini index (measured in a scale from 0 to 100). This is an ecological study that employs a linear regression model that relates the neonatal mortality rate (dependent variable) to the Gini index (independent variable), while controlling for other factors that influence neonatal mortality. Coefficient estimates and their robust standard errors were obtained using panel data techniques. Results A positive relationship between income inequality and neonatal mortality is found in countries in the Americas during the period studied. In particular, the analysis suggests that a unit increase in a country’s Gini index during 2000–2019 is associated with a 0.27 (95% CI [− 0.04, 0.57], P =.09) increase in the neonatal mortality rate. Conclusion The analysis suggests that income inequality may be positively associated with the neonatal mortality rate in the Americas. Nonetheless, given the modest magnitude of the estimates and Gini values and trends during 2000–2019, the findings suggest a potential limited scope for redistributive policies to support reductions in neonatal mortality in the region. Thus, policies and interventions that address higher coverage and quality of services provided by national health systems and reductions in socio-economic inequalities in health are of utmost importance.

Objective. To analyze temporal trends and inequalities in neonatal mortality between 2000 and 2020, and to set neonatal mortality targets for 2025 and 2030 in the Americas. Methods. A descriptive ecological study was conducted using 33 countries of the Americas as units of analysis. Both the percentage change and average annual percentage change in neonatal mortality rates were estimated. Measurements of absolute and relative inequality based on adjusted regression models were used to assess cross-country social inequalities in neonatal mortality. Targets to reduce neonatal mortality and cross-country inequalities were set for 2025 and 2030. Results. The estimated regional neonatal mortality rate was 12.0 per 1 000 live births in 20002004 and 7.4 per 1 000 live births in 2020, representing a percentage change of 38.3% and an average annual percentage change of 2.7%. National average annual percentage changes in neonatal mortality rates between 20002004 and 2020 ranged from 5.5 to 1.9 and were mostly negative. The estimated excess neonatal mortalityin the 20% most socially disadvantaged countries, compared with the 20% least socially disadvantaged countries, was 17.1 and 9.8 deaths per 1 000 live births in 20002004 and 2020, respectively. Based on an extrapolation of recent trends, the regional neonatal mortality rate is projected to reach 7.0 and 6.6 neonatal deaths per 1 000 live births by 2025 and 2030, respectively. Conclusions. National and regional health authorities need to strengthen their efforts to reduce persistent social inequalities in neonatal mortality both within and between countries.

La iniciativa Todas las Mujeres Todos los Niños América Latina y el Caribe (EWEC-LAC, por su sigla en inglés) se estableció en el 2017 como un mecanismo interinstitucional regional. Coordina la implementación regional de la Estrategia Mundial para la Salud de la Mujer, el Niño y el Adolescente 2016-2030 en América Latina y el Caribe (ALC), lo que incluye su adaptación a necesidades específicas de la Región, para poner fin a las muertes evitables, garantizar la salud y el bienestar, y ampliar los entornos propicios para la salud y el bienestar de mujeres, niños y adolescentes. Para promover el logro equitativo de estos objetivos, los tres grupos de trabajo de EWEC-LAC apoyan colectivamente a los países de ALC en la medición y el monitoreo de las desigualdades sociales en la salud, la promoción de la disminución de estas y el diseño e implementación de estrategias, políticas e intervenciones orientadas a la equidad. Este apoyo para cerrar las brechas actuales asegura que nadie se quede atrás. Los miembros de la iniciativa EWEC-LAC incluyen al UNFPA, la OPS, ONU-Mujeres, ONUSIDA, UNICEF, el Banco Mundial, el Banco Interamericano de Desarrollo, USAID, la Alianza Regional Neonatal para ALC y el Grupo de Trabajo Regional para la Reducción de la Mortalidad Materna. A la fecha, EWEC-LAC ha desarrollado y recopilado herramientas y recursos innovadores, y ha comenzado a colaborar con los países para utilizarlos a fin de reducir las brechas en la equidad. Estos incluyen un marco de medición de las desigualdades sociales en la salud, herramientas de promoción de datos, como un tablero de datos para visualizar tendencias en las desigualdades sociales en la salud, una metodología para establecer metas en la disminución de las desigualdades, y un compendio de herramientas y métodos para identificar y abordar las desigualdades sociales en la salud. EWEC-LAC ha trabajado en la Región para enfatizar la importancia de reconocer estas desigualdades a los niveles sociales y políticos, y ha abogado por su disminución. La atención para cerrar las brechas de equidad en la salud es cada vez más crítica frente a la pandemia de COVID-19, que ha agudizado las vulnerabilidades existentes. Los sistemas de salud más equitativos estarán mejor preparados para hacer frente a futuras crisis de salud.

High-throughput phenotype assays are a cornerstone of systems biology as they allow direct measurements of mutations, genes, strains, or even different genera. High-throughput methods also require data analytic methods that reduce complex time-series data to a single numeric evaluation. Here, we present the Growth Score, an improvement on the previous Growth Level formula. There is strong correlation between Growth Score and Growth Level, but the new Growth Score contains only essential growth curve properties while the formula of the previous Growth Level was convoluted and not easily interpretable. Several programs can be used to estimate the parameters required to calculate the Growth Score metric, including our PMAnalyzer pipeline.

Genomics and metagenomics have revolutionized our understanding of marine microbial ecology and the importance of microbes in global geochemical cycles. However, the process of DNA sequencing has always been an abstract extension of the research expedition, completed once the samples were returned to the laboratory. During the 2013 Southern Line Islands Research Expedition, we started the first effort to bring next generation sequencing to some of the most remote locations on our planet. We successfully sequenced twenty six marine microbial genomes, and two marine microbial metagenomes using the Ion Torrent PGM platform on the Merchant Yacht Hanse Explorer. Onboard sequence assembly, annotation, and analysis enabled us to investigate the role of the microbes in the coral reef ecology of these islands and atolls. This analysis identified phosphonate as an important phosphorous source for microbes growing in the Line Islands and reinforced the importance of L-serine in marine microbial ecosystems. Sequencing in the field allowed us to propose hypotheses and conduct experiments and further sampling based on the sequences generated. By eliminating the delay between sampling and sequencing, we enhanced the productivity of the research expedition. By overcoming the hurdles associated with sequencing on a boat in the middle of the Pacific Ocean we proved the flexibility of the sequencing, annotation, and analysis pipelines.

One of the major goals in metagenomics is to identify the organisms present in a microbial community from unannotated shotgun sequencing reads. Taxonomic profiling has valuable applications in biological and medical research, including disease diagnostics. Most currently available approaches do not scale well with increasing data volumes, which is important because both the number and lengths of the reads provided by sequencing platforms keep increasing. Here we introduce FOCUS, an agile composition based approach using non-negative least squares (NNLS) to report the organisms present in metagenomic samples and profile their abundances. FOCUS was tested with simulated and real metagenomes, and the results show that our approach accurately predicts the organisms present in microbial communities. FOCUS was implemented in Python.
