Accuracy; Atrial fibrillation; SmartwatchPrecisión; Fibrilación auricular; Reloj inteligentePrecisió; Fibril·lació auricular; Rellotge intel·ligentBackground: Consumer smartwatches may be a helpful tool to screen for atrial fibrillation (AF). However, validation studies on older stroke patients remain scarce. The aim of this pilot study from RCT NCT05565781 was to validate the resting heart rate (HR) measurement and the irregular rhythm notification (IRN) feature in stroke patients in sinus rhythm (SR) and AF. (2) Methods: Resting clinical HR measurements (every 5 min) were assessed using continuous bedside ECG monitoring (CEM) and the Fitbit Charge 5 (FC5). IRNs were gathered after at least 4 h of CEM. Lin’s concordance correlation coefficient (CCC), Bland-Altman analysis, and mean absolute percentage error (MAPE) were used for agreement and accuracy assessment. (3) Results: In all, 526 individual pairs of measurements were obtained from 70 stroke patients—age 79.4 years (SD ± 10.2), 63% females, BMI 26.3 (IQ 22.2–30.5), and NIHSS score 8 (IQR 1.5–20). The agreement between the FC5 and CEM was good (CCC 0.791) when evaluating paired HR measurements in SR. Meanwhile, the FC5 provided weak agreement (CCC 0.211) and low accuracy (MAPE 16.48%) when compared to CEM recordings in AF. Regarding the accuracy of the IRN feature, analysis found a low sensitivity (34%) and high specificity (100%) for detecting AF. (4) Conclusion: The FC5 was accurate at assessing the HR during SR, but the accuracy during AF was poor. In contrast, the IRN feature was acceptable for guiding decisions regarding AF screening in stroke patients.This study was funded by the Instituto de Salud Carlos III and the European Union (ERDF/ESF)—A way to build Europe (PI20/01210). Funding was also received in the framework of the “Digital Health Research Promotion Program: from the idea to the project” from the eHealth Center of the Universitat Oberta de Catalunya (UOC)

In print como método não invasivo de coleta de amostra para o diagnóstico molecular da leishmaniose cutânea em população militar da Colômbia

Taking into account that the traditional methods of sampling and diagnosis for cutaneous leishmaniasis , have limitations, such as direct smear, whose sensitivity depends on the professional's expertise, the lesion aspiration that can be used to detect parasites in the lamina, dna or cultures takes a long time and is demanding, and the biopsy of the lesion that is invasive and painful were compared with the imprinting method on the filter paper of the ulcerative lesion against the traditional method of aspiration by means of the conventional pcr technique using as a target a dna region of the parasite kinetoplast. In this present work, pcr obtained an imprinting sensitivity of 90.07% compared to the aspirate of 86.3%, which, besides being a non-invasive sampling method, with few transport requirements, it can be taken directly in the area of operations at a very low cost, which turns out to be beneficial to be used in patients with cutaneous leishmaniasis of the National Army of Colombia, who are in different operations areas.Teniendo en cuenta que los métodos tradicionales de toma de muestra y diagnóstico para la leishmaniosis cutánea presentan limitaciones, como el frotis directo, cuya sensibilidad depende de la pericia del profesional, el aspirado de lesión que puede ser usado para detección de parásitos en lámina, su adn o para cultivos es demorado y exigente, y la biopsia de la lesión que es invasiva y dolorosa se comparó con el método de impronta en papel filtro de la lesión ulcerativa contra el método tradicional de aspirado mediante la técnica de pcr convencional utilizando como blanco una región del adn del kinetoplasto del parásito. En el presente trabajo, la pcr obtuvo una sensibilidad para impronta del 90,07% comparado con el aspirado, el 86,3%, que, además, por ser un método de toma de muestra no invasivo, con pocas exigencias para el transporte, se puede tomar directamente en el área de operaciones a muy bajo costo, resulta ser beneficioso para ser usado en los pacientes con leishmaniosis cutánea del Ejército Nacional de Colombia, que se encuentran en las diferentes áreas de operaciones.Considerando que os métodos tradicionais de coleta de amostra e diagnóstico para a leishmaniose cutânea apresentam limitações, como exame direto de esfregaços, cuja sensibilidade depende da perícia do profissional, o raspado de lesão que pode ser usado para a detecção de parasitas em lâmina, seu dna ou para culturas é demorado e exigente, e a biopsia da lesão que é invasiva e dolorosa, comparou-se com o método in print em papel filtro da lesão ulcerativa contra o método tradicional de aspirado mediante a técnica de pcr convencional utilizando como alvo uma região do dna do cinetoplasto do parasita. No presente trabalho, a pcr obteve uma sensibilidade para in print de 90,07% comparado com o aspirado, 86,3%, que, além disso, por ser um método de coleta de amostra não invasivo, com poucas exigências para o transporte, pode ser coletado diretamente na área de operações a muito baixo custo, resulta ser benéfico para ser usado nos pacientes com leishmaniose cutânea do Exército Nacional da Colômbia, que se encontram nas diferentes áreas de operações

Prospección fitosanitaria en sistemas productivos hortícolas del cinturón verde de Córdoba (CVC).

La producción hortícola de la zona periurbana de la Ciudad de Córdoba (Cinturón Verde de Córdoba-CVC) se encuentra en franco retroceso. Unas de sus principales limitantes son las enfermedades y plagas, cuyo manejo adecuado y eficiente depende de la correcta identificación del organismo causal. En un trabajo interdisciplinario e interinstitucional, se realizó un relevamiento fitopatológico en fincas de productores fruti-hortícolas del CVC con diferentes planteos productivos. Como resultado, se identificaron los agentes causales de las enfermedades fúngicas y virales más frecuentes, como así también la entomofauna vinculada a la producción hortícola en el CVC. La información sistematizada será puesta a disposición de los productores a través de cartillas con fotos e información biológica y técnica, que constituya una herramienta útil para la identificación y manejo adecuado de los diferentes agentes biológicos.Instituto de Patología VegetalFil: Pastor, Silvina Estela.

Novel genes and sex differences in COVID-19 severity

[EN] Here, we describe the results of a genome-wide study conducted in 11 939 coronavirus disease 2019 (COVID-19) positive cases with an extensive clinical information that were recruited from 34 hospitals across Spain (SCOURGE consortium). In sex-disaggregated genome-wide association studies for COVID-19 hospitalization, genome-wide significance (P < 5 × 10−8) was crossed for variants in 3p21.31 and 21q22.11 loci only among males (P = 1.3 × 10−22 and P = 8.1 × 10−12, respectively), and for variants in 9q21.32 near TLE1 only among females (P = 4.4 × 10−8). In a second phase, results were combined with an independent Spanish cohort (1598 COVID-19 cases and 1068 population controls), revealing in the overall analysis two novel risk loci in 9p13.3 and 19q13.12, with fine-mapping prioritized variants functionally associated with AQP3 (P = 2.7 × 10−8) and ARHGAP33 (P = 1.3 × 10−8), respectively. The meta-analysis of both phases with four European studies stratified by sex from the Host Genetics Initiative (HGI) confirmed the association of the 3p21.31 and 21q22.11 loci predominantly in males and replicated a recently reported variant in 11p13 (ELF5, P = 4.1 × 10−8). Six of the COVID-19 HGI discovered loci were replicated and an HGI-based genetic risk score predicted the severity strata in SCOURGE. We also found more SNP-heritability and larger heritability differences by age (<60 or ≥60 years) among males than among females. Parallel genome-wide screening of inbreeding depression in SCOURGE also showed an effect of homozygosity in COVID-19 hospitalization and severity and this effect was stronger among older males. In summary, new candidate genes for COVID-19 severity and evidence supporting genetic disparities among sexes are provided.S

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Photography-based taxonomy is inadequate, unnecessary, and potentially harmful for biological sciences

The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Repositioning of the global epicentre of non-optimal cholesterol

High blood cholesterol is typically considered a feature of wealthy western countries(1,2). However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world(3) and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health(4,5). However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol-which is a marker of cardiovascular riskchanged from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million-4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.Peer reviewe

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.
