    Continuous monitoring of arterial blood pressure (ABP) of patients in hospital is currently carried out in an invasive way, which could represent a risk for them. In this paper, a noninvasive methodology to optimize ABP estimators using electrocardiogram and photoplethysmography signals is proposed. For this, the XGBoost machine learning model, optimized with Bayesian techniques, is executed in a Graphics Processing Unit, which drastically reduces execution time. The methodology is evaluated using the MIMIC-III Waveform Database. Systolic and diastolic pressures are estimated with mean absolute error values of 15.85 and 11.59 mmHg, respectively, similar to those of the state of the art. The main advantage of the proposed methodology with respect to others of the current state of the art is that it allows the optimization of the estimator model to be performed automatically and more efficiently at the computational level for the data available. Clinical Relevance— This approach has the advantage of using noninvasive methods to continuously monitor patient's arterial blood pressure, reducing the risk for patientsAgencia Gallega de Innovación | Ref.

Characterising the differential impact of severe versus moderate paediatric haemophilia is important for clinical and health policy decisions. We analysed health-related quality of life (HRQoL), annual direct medical (excluding factor treatment costs), non-medical and societal costs among children and adolescents with moderate and severe haemophilia A or B without inhibitors from the European CHESS-PAEDs study. Information was reported by physicians and caregivers; patients aged ≥ 8 years self-reported their HRQoL. Descriptive statistics summarised demographic and clinical characteristics, costs, and HRQoL scores (EQ-5D-Y). Regression models estimated differences in HRQoL and costs for moderate versus severe haemophilia adjusting for age, body mass index z-score, country, number of comorbidities, and weight-adjusted annual clotting factor consumption.ResultsThe analytic sample comprised 794 patients with a mean age of 10.5 years; most had haemophilia A (79%) and 58% had severe haemophilia. Mean predicted direct medical costs in moderate patients were two-thirds of the predicted costs for severe disease (€3065 vs. €2047; p ConclusionChildren with haemophilia and their caregivers displayed a significant economic and humanistic burden. While severe patients showed the highest direct medical and societal costs, and worse HRQoL, the burden of moderate haemophilia on its own was substantial and far from negligible

    From Europe PMC via Jisc Publications RouterHistory: ppub 2022-04-01, epub 2022-04-04Publication status: PublishedFunder: Sanofi; Grant(s): SanofiBackgroundThe lifelong nature of haemophilia makes patient-centred and societal assessments of its impact important to clinical and policy decisions. Quantifying the humanistic and economic burden by severity is key to assessing the impact on healthcare systems. We analysed the annual direct medical (excluding factor replacement therapy costs) and non-medical costs as well as societal costs and health-related quality of life (HRQoL) of mild, moderate and severe disease among adults with haemophilia A or B without inhibitors in Europe. Participants in the CHESS II study reported their HRQoL, non-medical costs, and work impairment; physicians provided costs and consultation history from the medical chart. Descriptive statistics summarized patient characteristics, costs, and HRQoL scores. Regression models estimated differences in outcomes for moderate and severe versus mild disease, adjusting for age, body mass index, country, comorbidities, weight-adjusted factor consumption and education.ResultsThe analytic sample included 707 patients with a mean age of 38 years; the majority of patients had haemophilia A (81%), and 47% had severe disease, followed by moderate (37%) and mild disease (16%). Patients with severe or moderate disease had on average higher direct costs, €3105 and €2469 respectively, versus mild disease. Societal costs were higher for patients with severe and moderate disease by €11,115 and €2825, respectively (all P ConclusionSeverity of haemophilia is predictive of increasing economic and humanistic burden.

    Development of a Panel of Genome-Wide Ancestry Informative Markers to Study Admixture Throughout the Americas

    Most individuals throughout the Americas are admixed descendants of Native American, European, and African ancestors. Complex historical factors have resulted in varying proportions of ancestral contributions between individuals within and among ethnic groups. We developed a panel of 446 ancestry informative markers (AIMs) optimized to estimate ancestral proportions in individuals and populations throughout Latin America. We used genome-wide data from 953 individuals from diverse African, European, and Native American populations to select AIMs optimized for each of the three main continental populations that form the basis of modern Latin American populations. We selected markers on the basis of locus-specific branch length to be informative, well distributed throughout the genome, capable of being genotyped on widely available commercial platforms, and applicable throughout the Americas by minimizing within-continent heterogeneity. We then validated the panel in samples from four admixed populations by comparing ancestry estimates based on the AIMs panel to estimates based on genome-wide association study (GWAS) data. The panel provided balanced discriminatory power among the three ancestral populations and accurate estimates of individual ancestry proportions (R2>0.9 for ancestral components with significant between-subject variance). Finally, we genotyped samples from 18 populations from Latin America using the AIMs panel and estimated variability in ancestry within and between these populations. This panel and its reference genotype information will be useful resources to explore population history of admixture in Latin America and to correct for the potential effects of population stratification in admixed samples in the region

    A regulated deficit irrigation strategy for hedgerow olive orchards with high plant density

    Background & Aims There is not a consensus on the best irrigation approach for super-high density (SHD) olive orchards. Our aim was to design and test a regulated deficit irrigation (RDI) strategy for a sustainable balance between water saving, tree vigour and oil production. Methods We tested our RDI strategy for 3 years in an ‘Arbequina’ orchard with 1,667 trees ha−1. Two levels of irrigation reduction were applied, 60RDI and 30RDI, scaled to replacing 60 % and 30 %, respectively, of the of irrigation needs (IN). We also had a full irrigation (FI) treatment as control, with IN totalling 4,701 m3 ha−1 Results The 30RDI treatment showed the best balance between water saving, tree vigour and oil production. With a yearly irrigation amount (IA) of 1,366 m3 ha−1, which meant 72 % water saving as compared to FI, the reduction in oil yield was 26 % only. Conclusions Our results, together with recent knowledge on the effect of water stress on fruit development, allowed us to suggest a potentially improved RDI strategy for which a total IA of ca. 2,100 m3 ha−1 was calculated. Both some management details and the benefits of this suggested RDI strategy are still to be tested
