Optical and mechanical properties of cocona chips as affected by the drying process

[EN] The effect of the application of a pre-osmotic treatment to obtain hot air dried cocona(Solanum sessiliofurum Dunal) chips was studied. The drying kinetics and the optical andmechanical properties of cocona chips obtained by the combined method of osmotic dehy-dration and hot air drying (OD + HAD) and by only hot air drying (HAD) were compared.Samples were dried by hot air at 60◦C. For the combined method, they were pre-dried toa moisture content of 75 gwater/100 g, immersed in a 55◦Brix sucrose solution at 25◦C for48 min. The pre-osmodehydration applied did not influence the subsequent hot air dryingkinetics, resulting in a final product with 0.055 ± 0.005 gwater/gcocona.The optical properties ofOD + HAD chips were more favorable, exhibiting a smaller color change with respect to thefresh fruit (±15 units) than the HAD samples (±23 units). On the other hand, the OD + HADchips presented more fracture peaks than HAD ones, this related with a structure with ahigher degree of crispness, a very desirable property for a chip product.The authors thank the Universidad Politecnica de Valencia for the financial support given throughout the Project ADSIDEO-COOPERACION 2010 "Adaptacion de procesos de secado para favorecer la comercializacion de super frutas de origen colombiano".Agudelo Sterling, CM.; Igual Ramo, M.; Talens Oliag, P.; Martínez Navarrete, N.

High interannual variability in connectivity and genetic pool of a temperate clingfish matches oceanographic transport predictions

Adults of most marine benthic and demersal fish are site-attached, with the dispersal of their larval stages ensuring connectivity among populations. In this study we aimed to infer spatial and temporal variation in population connectivity and dispersal of a marine fish species, using genetic tools and comparing these with oceanographic transport. We focused on an intertidal rocky reef fish species, the shore clingfish Lepadogaster lepadogaster, along the southwest Iberian Peninsula, in 2011 and 2012. We predicted high levels of self-recruitment and distinct populations, due to short pelagic larval duration and because all its developmental stages have previously been found near adult habitats. Genetic analyses based on microsatellites countered our prediction and a biophysical dispersal model showed that oceanographic transport was a good explanation for the patterns observed. Adult sub-populations separated by up to 300 km of coastline displayed no genetic differentiation, revealing a single connected population with larvae potentially dispersing long distances over hundreds of km. Despite this, parentage analysis performed on recruits from one focal site within the Marine Park of Arrabida (Portugal), revealed self-recruitment levels of 2.5% and 7.7% in 2011 and 2012, respectively, suggesting that both long-and short-distance dispersal play an important role in the replenishment of these populations. Population differentiation and patterns of dispersal, which were highly variable between years, could be linked to the variability inherent in local oceanographic processes. Overall, our measures of connectivity based on genetic and oceanographic data highlight the relevance of long-distance dispersal in determining the degree of connectivity, even in species with short pelagic larval durations

Global, regional, and national burden of chronic kidney disease, 1990–2017 : a systematic analysis for the Global Burden of Disease Study 2017

Background Health system planning requires careful assessment of chronic kidney disease (CKD) epidemiology, but data for morbidity and mortality of this disease are scarce or non-existent in many countries. We estimated the global, regional, and national burden of CKD, as well as the burden of cardiovascular disease and gout attributable to impaired kidney function, for the Global Burden of Diseases, Injuries, and Risk Factors Study 2017. We use the term CKD to refer to the morbidity and mortality that can be directly attributed to all stages of CKD, and we use the term impaired kidney function to refer to the additional risk of CKD from cardiovascular disease and gout. Methods The main data sources we used were published literature, vital registration systems, end-stage kidney disease registries, and household surveys. Estimates of CKD burden were produced using a Cause of Death Ensemble model and a Bayesian meta-regression analytical tool, and included incidence, prevalence, years lived with disability, mortality, years of life lost, and disability-adjusted life-years (DALYs). A comparative risk assessment approach was used to estimate the proportion of cardiovascular diseases and gout burden attributable to impaired kidney function. Findings Globally, in 2017, 1·2 million (95% uncertainty interval [UI] 1·2 to 1·3) people died from CKD. The global all-age mortality rate from CKD increased 41·5% (95% UI 35·2 to 46·5) between 1990 and 2017, although there was no significant change in the age-standardised mortality rate (2·8%, −1·5 to 6·3). In 2017, 697·5 million (95% UI 649·2 to 752·0) cases of all-stage CKD were recorded, for a global prevalence of 9·1% (8·5 to 9·8). The global all-age prevalence of CKD increased 29·3% (95% UI 26·4 to 32·6) since 1990, whereas the age-standardised prevalence remained stable (1·2%, −1·1 to 3·5). CKD resulted in 35·8 million (95% UI 33·7 to 38·0) DALYs in 2017, with diabetic nephropathy accounting for almost a third of DALYs. Most of the burden of CKD was concentrated in the three lowest quintiles of Socio-demographic Index (SDI). In several regions, particularly Oceania, sub-Saharan Africa, and Latin America, the burden of CKD was much higher than expected for the level of development, whereas the disease burden in western, eastern, and central sub-Saharan Africa, east Asia, south Asia, central and eastern Europe, Australasia, and western Europe was lower than expected. 1·4 million (95% UI 1·2 to 1·6) cardiovascular disease-related deaths and 25·3 million (22·2 to 28·9) cardiovascular disease DALYs were attributable to impaired kidney function. Interpretation Kidney disease has a major effect on global health, both as a direct cause of global morbidity and mortality and as an important risk factor for cardiovascular disease. CKD is largely preventable and treatable and deserves greater attention in global health policy decision making, particularly in locations with low and middle SDI

Parental and infant characteristics and childhood leukemia in Minnesota

<p>Abstract</p> <p>Background</p> <p>Leukemia is the most common childhood cancer. With the exception of Down syndrome, prenatal radiation exposure, and higher birth weight, particularly for acute lymphoid leukemia (ALL), few risk factors have been firmly established. Translocations present in neonatal blood spots and the young age peak of diagnosis suggest that early-life factors are involved in childhood leukemia etiology.</p> <p>Methods</p> <p>We investigated the association between birth characteristics and childhood leukemia through linkage of the Minnesota birth and cancer registries using a case-cohort study design. Cases included 560 children with ALL and 87 with acute myeloid leukemia (AML) diagnoses from 28 days to 14 years. The comparison group was comprised of 8,750 individuals selected through random sampling of the birth cohort from 1976–2004. Cox proportional hazards regression specific for case-cohort studies was used to compute hazard ratios (HR) and 95% confidence intervals (CIs).</p> <p>Results</p> <p>Male sex (HR = 1.41, 95% CI 1.16–1.70), white race (HR = 2.32, 95% CI 1.13–4.76), and maternal birth interval ≥ 3 years (HR = 1.31, 95% CI 1.01–1.70) increased ALL risk, while maternal age increased AML risk (HR = 1.21/5 year age increase, 95% CI 1.0–1.47). Higher birth weights (>3798 grams) (HRALL = 1.46, 1.08–1.98; HRAML = 1.97, 95% CI 1.07–3.65), and one minute Apgar scores ≤ 7 (HRALL = 1.30, 95% CI 1.05–1.61; HRAML = 1.62, 95% CI 1.01–2.60) increased risk for both types of leukemia. Sex was not a significant modifier of the association between ALL and other covariates, with the exception of maternal education.</p> <p>Conclusion</p> <p>We confirmed known risk factors for ALL: male sex, high birth weight, and white race. We have also provided data that supports an increased risk for AML following higher birth weights, and demonstrated an association with low Apgar scores.</p

Movilidad urbana y pobreza: Aprendizajes de Medellín y Soacha, Colombia

Este libro es un análisis de la experiencia de Medellín, la segunda ciudad de Colombia, en intentar reducir la pobreza e integrar en el tejido urbano barrios marginalizados y estigmatizados durante muchos años por la pobreza y la violencia. En particular, examina el impacto de dos cables aéreos que conectan densos barrios en colinas empinadas con el resto de la ciudad, y un programa de mejoramiento urbano asociado a estos. También contrasta la experiencia exitosa de Medellín con la de Soacha, un municipio adyacente a Bogotá, la capital colombiana, donde se ha propuesto un cable aéreo como medio de conexión de dos barrios en colina con una vía arteria. El contraste entre un municipio bien gestionado y abundante en recursos como Medellín con un municipio denso, homogéneamente pobre e institucionalmente débil como Soacha ofrece aprendizajes muy valiosos para otras ciudades en América Latina y otras regiones del mundo. La mayor parte de los capítulos se apoyan en un proyecto de investigación de dos años coordinado por la Development Planning Unit, University College London (UCL), en asocio con la Universidad Nacional de Colombia (sede Medellín) y la Universidad de los Andes de Bogotá. Además de estudios de caso detallados de Medellín y Soacha, el libro agrupa también casos en América Latina en donde se han construido o se han propuesto cables aéreos en barrios de bajos ingresos, como Caracas y Rio de Janeiro

Urban Mobility and Poverty: Lessons from Medellin and Soacha, Colombia

This book examines the experience of Medellín, Colombia's second largest city, in seeking to reduce poverty and integrate large marginalised areas, marked by years of severe poverty and violence, into the urban fabric. It pays particular attention to the impact of two aerial cable-cars connecting high density hilly neighbourhoods with the rest of the city, and an associated urban upgrading programme. It also contrasts Medellín’s successful experience with that of Soacha, a municipality adjacent to Bogotá, Colombia’s capital city, where an aerial cable-car has been proposed as a means of linking two low-income hilly neighbourhoods with a main arterial road. The contrast between a well-resourced, well-managed municipality like Medellín with a dense and homogenously poor and institutionally weak municipality like Soacha offers valuable lessons to other cities in Latin America and elsewhere. Contributions draw from a two-year research project coordinated by the Development Planning Unit, University College London (UCL), in conjunction with Universidad Nacional de Colombia (Medellín campus) and Universidad de los Andes in Bogotá. In addition to the detailed case studies of Medellín and Soacha, the book also brings together cases in Latin America where aerial cable-cars have either been built or proposed in low-income neighbourhoods, including Caracas and Rio de Janeiro
