Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.
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.

Variação sazonal do enraizamento de estacas de cultivares de Vitis rotundifolia Seasonal variation of rooting on stem cuttings of Vitis rotundifolia cultivars
Este trabalho objetivou avaliar o enraizamento de 9 cultivares de Vitis rotundifolia nas quatro épocas do ano (verão, outono, inverno e primavera). As cultivares estudadas foram as seguintes: Topsail, Magnolia, Creek, Noble, Roanoke, Magoon, Regale, Bontiful e Dixie, sendo a estaquia realizada em câmara de nebulização intermitente, com o intervalo de rega controlado de acordo com a época do ano. O delineamento utilizado foi o inteiramente casualizado, com quatro repetições, nove tratamentos e 15 estacas por parcela. Todos os experimentos foram avaliados após 75 dias, levando-se em consideração as seguintes variáveis: porcentagem de estacas com folha e porcentagem de estacas enraizadas por parcela; número de raízes; comprimento (cm) das raízes principais e massa seca das raízes por estaca (mg). Nas estacas lenhosas, retiradas no outono e no inverno, não se obteve enraizamento. Com as estacas semilenhosas, retiradas no verão e na primavera, ocorreu enraizamento em todas as cultivares, com destaque para as cultivares Magnolia e Noble na primavera, que apresentaram 61,66% e 51,66% de enraizamento, respectivamente. Nessa época, também ocorreu maior retenção foliar. A cultivar Bontiful demonstrou grande dificuldade de enraizamento. Para a propagação de cultivares de V. rotundifolia, recomenda-se a estaquia semilenhosa durante a primavera.<br>The objective of this work was to evaluate the rooting on cuttings of nine Vitis rotundifolia cultivars during the seasons of the year (summer, autumn, winter and spring). The evaluated cultivars were: Topsail, Magnolia, Creek, Noble, Roanoke, Magoon, Regale, Bontiful e Dixie. The experiment was carried out under intermittent mist chamber, with irrigation controled according with the season of the year. The experimental design was in randomized blocks with nine treatments, each one with 4 replicates containing 15 stem cuttings. All experiments were evaluated after 75 days after planting and the following variables were determined: percentage of cuttings with leaf and percentage of rooted cutting per plot; number of roots, length (cm) of main roots and dried mass of roots per cuttings. No roots developed on lignified cutings collected from plants during fall and winter. Cuttings collected from all cultivars during the summer and spring, were succesfully rooted, being superior on Magnolia and Noble cultivars during the spring, that showed 61.66% and 51.66% of rooting rate, respectively. This season also showed great leaf retention. The lowest percentage or rooting was observed for stem cuttings of the cultivar Bontiful. The resulst finally showed that spring is the best season for rooting of V. rotundifolia stem cuttings
