Unexplored olive cultivars from the Valencian Community (Spain): some chemical characteristics as a valorization strategy

[EN] The olive processing industry has till date been dominated by a small group of cultivars, leading to the possibility of some olive cultivars becoming extinct in the near future. In this study, we determined the composition of some chemical components in the olive oils from 31 minor olive cultivars of the Valencian Community. Our main aim was to identify suitable cultivars, which could produce differentiated olive oils, thus aiming towards their valorization. The average oil content of minor olive cultivars was found to be good, with some of them reporting approximately 60% (dry basis). On average, the total phenolic content was 229mg kg(-1), with cv. Mas Blanc reporting the highest content (570mg kg(-1)). Among the various tocopherols found in olives, -tocopherol was the main constituent, with a maximum concentration of 290.6mg kg(-1). Linoleic acid was the main polyunsaturated fatty acid and varied between 3.4% (cv. Del Pomet) and 16.9% (cv. Blanqueta Enguera). Special attention needs to be paid to the composition of sterols, since some olive oils exceeded the limits established for some sterols by the current European legislation. Some of the cultivars studied were highly productive, and originated differentiated olive oils with a rich composition of antioxidants and essential fatty acids. In some cases, these beneficial compounds were higher than those of commercial oils obtained from the most common cultivars worldwide. These results could contribute to the commercial exploitation of some of the studied cultivars.Salazar-García, DC.; Malheiro, R.; Pereira, JA.; López- Cortés, I. (2019).

Whole-genome sequencing reveals host factors underlying critical COVID-19

Critical COVID-19 is caused by immune-mediated inflammatory lung injury. Host genetic variation influences the development of illness requiring critical care1 or hospitalization2,3,4 after infection with SARS-CoV-2. The GenOMICC (Genetics of Mortality in Critical Care) study enables the comparison of genomes from individuals who are critically ill with those of population controls to find underlying disease mechanisms. Here we use whole-genome sequencing in 7,491 critically ill individuals compared with 48,400 controls to discover and replicate 23 independent variants that significantly predispose to critical COVID-19. We identify 16 new independent associations, including variants within genes that are involved in interferon signalling (IL10RB and PLSCR1), leucocyte differentiation (BCL11A) and blood-type antigen secretor status (FUT2). Using transcriptome-wide association and colocalization to infer the effect of gene expression on disease severity, we find evidence that implicates multiple genes—including reduced expression of a membrane flippase (ATP11A), and increased expression of a mucin (MUC1)—in critical disease. Mendelian randomization provides evidence in support of causal roles for myeloid cell adhesion molecules (SELE, ICAM5 and CD209) and the coagulation factor F8, all of which are potentially druggable targets. Our results are broadly consistent with a multi-component model of COVID-19 pathophysiology, in which at least two distinct mechanisms can predispose to life-threatening disease: failure to control viral replication; or an enhanced tendency towards pulmonary inflammation and intravascular coagulation. We show that comparison between cases of critical illness and population controls is highly efficient for the detection of therapeutically relevant mechanisms of disease

Suplementación de yodo en la gestación y lactancia

l beneficio de la suplementación con yodo durante la gestación en las áreas con deficiencia grave de yodo está bien establecido. En el año 2004 la Organización Mundial de la Salud incluyó a España entre los países con adecuada ingesta de yodo y varios estudios recientes confirman que la ingesta de yodo es suficiente en la población española. Los profesionales españoles, sin embargo, se han encontrado con recomendaciones contradictorias, lo que ha generado confusión e incertidumbre en la práctica a seguir en cuanto a la suplementación de yodo a la mujer gestante o en periodo de lactancia. A los clínicos e investigadores les preocupa que las situaciones de déficit de yodo leve o moderado puedan relacionarse con un peor desarrollo de los niños, pero la suplementación rutinaria de yodo en la gestación no está exenta de riesgo. PrevInfad considera que, al tratarse de una medida profiláctica que afecta a dos individuos -madre e hijo- y que se aplica al conjunto de una población sana, debe primar el principio de precaución y que no existen pruebas de calidad suficiente para determinar el balance entre los beneficios y los riesgos de la suplementación farmacológica de yodo durante la gestación y la lactancia, por lo que sugiere que no se realice esta intervención. The benefits of Iodine supplementation in Iodine-deficient areas are well established. The World Health Organization included Spain among the countries with an adequate Iodine intake in 2004 and some recent research papers confirm that Iodine intake is adequate in the Spanish population. Nevertheless, Spanish health professionals have been faced with contradictory recommendations, producing confusion and uncertainty in clinical practice referring to Iodine supplementation in pregnancy and breastfeeding mothers. Clinicians and researchers are concerned that mild or moderate Iodine deficiency could be related to underdevelopment in children, but routine Iodine supplementation in pregnancy is not risk free. The working group PrevInfad (Prevention in Childhood and Adolescence) considers that being a preventive intervention that applies to the total healthy population, the precaution principle must be prioritized, and that there is no evidence on the balance risk-benefit in the pharmacological Iodine supplementation during pregnancy and breastfeeding. For these reasons they suggest not making this intervention

Prediction of long-term outcomes of HIV-infected patients developing non-AIDS events using a multistate approach

Outcomes of people living with HIV (PLWH) developing non-AIDS events (NAEs) remain poorly defined. We aimed to classify NAEs according to severity, and to describe clinical outcomes and prognostic factors after NAE occurrence using data from CoRIS, a large Spanish HIV cohort from 2004 to 2013. Prospective multicenter cohort study. Using a multistate approach we estimated 3 transition probabilities: from alive and NAE-free to alive and NAE-experienced ("NAE development"); from alive and NAE-experienced to death ("Death after NAE"); and from alive and NAE-free to death ("Death without NAE"). We analyzed the effect of different covariates, including demographic, immunologic and virologic data, on death or NAE development, based on estimates of hazard ratios (HR). We focused on the transition "Death after NAE". 8,789 PLWH were followed-up until death, cohort censoring or loss to follow-up. 792 first incident NAEs occurred in 9.01% PLWH (incidence rate 28.76; 95% confidence interval [CI], 26.80-30.84, per 1000 patient-years). 112 (14.14%) NAE-experienced PLWH and 240 (2.73%) NAE-free PLWH died. Adjusted HR for the transition "Death after NAE" was 12.1 (95%CI, 4.90-29.89). There was a graded increase in the adjusted HRs for mortality according to NAE severity category: HR (95%CI), 4.02 (2.45-6.57) for intermediate-severity; and 9.85 (5.45-17.81) for serious NAEs compared to low-severity NAEs. Male sex (HR 2.04; 95% CI, 1.11-3.84), ag
