    Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and ≥1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (n = 5069) or prospectively (n = 5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (≤6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; p = 0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.

    BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

    The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

    Se realizó una investigación transversal analítica, multicéntrica, en donde se encuestó a padres e hijos con la escala DASS-21, haciendo los cruces y ajustando por algunas otras variables. De los 1832 estudiantes y 1832 jefes de familia encuestados, según el tener una presentación severa, el 35% de los padres tenían estrés (p<0,001), el 44% tenían ansiedad (p<0,001) y el 25% tenían depresión (p<0,001), esto si sus hijos tenían entrés, ansiedad o depresión severos; respectivamente. Si el jefe de familia presentó depresión moderada/severa se asoció con que sus hijos tengan depresión o ansiedad; el que el padre de familia padezca de ansiedad moderada/severa se asoció con el hecho de que los hijos tengan también depresión o ansiedad y el que los jefes de familia presenten cuadros de estrés moderado/severo tuvo asociación con que los hijos tuviesen ansiedad y estrés (hasta aquí todos los valores p<0,002); así como, que los jefes del hogar fuesen mujeres (p=0,034). Se encontró una evidente asociación de los problemas de la salud mental de los hijos con los de sus padres, esto debe alertar de que existen hogares completos con problemas mentales, y que guardan relación del padecimiento de las patologías

    Introduction: Fear is a natural response to something unknown. In the current scenario, it is important to assess it in relation to the coronavirus disease-19 (COVID-19) pandemic in Latin American countries. Objective: To determine the fear perception according to factors associated with the COVID-19 pandemic in Peru. Methods: An analytical cross-sectional study was conducted based on a virtual questionnaire. The main question was “how much fear people had of COVID-19?”, using a scale from zero (without fear) to 10 (very fear). This scale was divided into tertiles, and the upper tertile was the reference category (compared to the middle and lower tertiles). Statistical significances between fear perception of COVID-19 and sociodemographic data were calculated. Results: A total of 3887 participants responded the questionnaire about fear perception. In the multivariate analysis was found that women (adjusted prevalence ratio (aPR): 1.37; 95% confidence interval (CI) : 1.26-1.48; p<0.001), people aged 20-29 (aPR: 1.84; 95% CI: 1.06-1.50; p=0.005), 30-39 (aPR: 1.53; 95% CI : 1.28-1.82; p<0.001), 50-59 (aPR: 1.43; 95% CI: 1.12-1.84; p=0.005), and with 60 or more years (aPR: 1.46; 95% CI: 1.03-2.07; p=0.032), as well as respondents who had some risk for complications due to COVID-19 (aPR: 1.49; 95% CI: 1.32-1.69; p<0.001) were very afraid of the disease. On the other hand, people affiliated with evangelical religions (aPR: 0.79; 95% CI: 0.65-0.96; p=0.018), agnostics (aPR: 0.80; 95% CI: 0.68-0.94; p=0.008), atheists (aPR: 0.67; 95% CI: 0.48-0.95; p=0.024), and health professionals (aPR: 0.81; 95% CI: 0.70-0.93; p=0.003) were less afraid of COVID-19. Conclusion: There was a notorious fear perception of the COVID-19 pandemic by the Peruvian population. In this context, the fear was associated with important variables. Thus, the provision of further emotional support services for this population should be considered in the face of the current pandemic

    Introduction: The COVID-19 pandemic has generated diverse reactions, but these have not yet been measured in the Latin American population.Objective: To determine the factors associated with the perception of fatalism in the face of COVID-19 infection in inhabitants of 20 cities in Peru.Material and Methods: A cross-sectional, multicenter study with a sample size of 2 466 people from 20 cities of Peru that measured fatalism during the COVID-19 pandemic was conducted through a validated survey (Cronbach´s alpha: 0,78) consisting of 7 items. Statistical analysis was conducted in terms of each city, and p < 0,05 was considered significant.Results: Of the 2 466 respondents, 36 % were depressed, 26 % thought that they might die, 17 % say that this was evidence of the end of the world, and 9 % could make a fatal decision. Women were more likely to engage in three of the fatalistic behaviors (becoming infected, p = 0,020; infecting others, p = 0,004, and becoming depressed, p = 0,020). At an older age there were 5 perceptions (infecting others, p = 0,007; becoming complicated, p < 0,001; becoming depressed, p < 0,001, thinking they would die, p < 0,001; or committing suicide, p = 0,014). Those at risk of complications of COVID-19 had 4 perceptions (infecting others, p = 0,024; becoming complicated, p = 0,002; thinking they would die, p < 0,001; and thinking that this is a sign of the end of the world, p = 0,039). Respondents who were agnostic exhibited a lower frequency in 5 perceptions, while atheist respondents showed a lower frequency in 2 perceptions.Conclusion: Many fatalistic ideas are found among the population in the face of the coronavirus pandemic.Introducción: la pandemia del COVID-19 ha generado reacciones diversas, pero estas aún no han sido medidas en la población latinoamericana.Objetivo: determinar los factores asociados a la percepción de fatalismo ante la infección del COVID-19 en pobladores de 20 departamentos del Perú. Material y Métodos: estudio transversal analítico, de tipo multicéntrico que con una muestra de 2466 personas en 20 departamentos del Perú midió el fatalismo ante la pandemia del COVID – 19 a través de una encuesta validada (Alpha Crombach: 0,78) que consistía en 7 ítems. El análisis estadístico fue realizado en función de cada ciudad y se consideró significativos p < 0,05.Resultados: de los 2466 encuestados, el 36 % se deprimirían, el 26 % piensa que podrían fallecer, el 17 % dice que esto es evidencia del fin del mundo y el 9 % podrían tomar una decisión fatal. Las mujeres tuvieron mayor frecuencia de 3 de las conductas fatalistas (contagiarse p=0,020; contagiar a otros p=0,004 y deprimirse p=0,020). A mayor edad hubo 5 percepciones (contagiar a otros p=0,007; complicarse p<0,001; deprimirse p<0,001, pensar que morirían p<0,001 o suicidarse p=0,014). Los que tenían un riesgo para complicación por COVID-19 tuvieron 4 percepciones (contagiar a otros p=0,024; complicarse p=0,002; pensar que morirían p<0,001 y que esto es señal del fin del mundo p=0,039). El ser agnóstico tuvo menor frecuencia de 5 percepciones, el ser ateo en 2.Conclusión: Se halló muchas ideas fatalistas entre la población ante la pandemia de coronavirus

    Vitamin K antagonist (VKA) therapy for stroke prevention in atrial fibrillation (AF) requires monitoring of the international normalized ratio (INR). We evaluated the agreement between two INR audit parameters, frequency in range (FIR) and proportion of time in the therapeutic range (TTR), using data from a global population of patients with newly diagnosed non-valvular AF, the Global Anticoagulant Registry in the FIELD\u2013Atrial Fibrillation (GARFIELD-AF). Among 17\ua0168 patients with 1-year follow-up data available at the time of the analysis, 8445 received VKA therapy (\ub1antiplatelet therapy) at enrolment, and of these patients, 5066 with 653 INR readings and for whom both FIR and TTR could be calculated were included in the analysis. In total, 70\ua0905 INRs were analysed. At the patient level, TTR showed higher values than FIR (mean, 56\ub70% vs 49\ub78%; median, 59\ub77% vs 50\ub70%). Although patient-level FIR and TTR values were highly correlated (Pearson correlation coefficient [95% confidence interval; CI], 0\ub7860 [0\ub7852\u20130\ub7867]), estimates from individuals showed widespread disagreement and variability (Lin's concordance coefficient [95% CI], 0\ub7829 [0\ub7821\u20130\ub7837]). The difference between FIR and TTR explained 17\ub74% of the total variability of measurements. These results suggest that FIR and TTR are not equivalent and cannot be used interchangeably
