The Changing Landscape for Stroke\ua0Prevention in AF: Findings From the GLORIA-AF Registry Phase 2

Background GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non\u2013vitamin K antagonist oral anticoagulant (NOAC), became available. Objectives This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase 1. Methods During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients\u2019 baseline characteristics. Atrial fibrillation disease characteristics, medical outcomes, and concomitant diseases and medications were collected. Data were analyzed using descriptive statistics. Results Of the total patients, 45.5% were female; median age was 71 (interquartile range: 64, 78) years. Patients were from Europe (47.1%), North America (22.5%), Asia (20.3%), Latin America (6.0%), and the Middle East/Africa (4.0%). Most had high stroke risk (CHA2DS2-VASc [Congestive heart failure, Hypertension, Age  6575 years, Diabetes mellitus, previous Stroke, Vascular disease, Age 65 to 74 years, Sex category] score  652; 86.1%); 13.9% had moderate risk (CHA2DS2-VASc = 1). Overall, 79.9% received oral anticoagulants, of whom 47.6% received NOAC and 32.3% vitamin K antagonists (VKA); 12.1% received antiplatelet agents; 7.8% received no antithrombotic treatment. For comparison, the proportion of phase 1 patients (of N = 1,063 all eligible) prescribed VKA was 32.8%, acetylsalicylic acid 41.7%, and no therapy 20.2%. In Europe in phase 2, treatment with NOAC was more common than VKA (52.3% and 37.8%, respectively); 6.0% of patients received antiplatelet treatment; and 3.8% received no antithrombotic treatment. In North America, 52.1%, 26.2%, and 14.0% of patients received NOAC, VKA, and antiplatelet drugs, respectively; 7.5% received no antithrombotic treatment. NOAC use was less common in Asia (27.7%), where 27.5% of patients received VKA, 25.0% antiplatelet drugs, and 19.8% no antithrombotic treatment. Conclusions The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in Asia and North America.

Resistência de genótipos de soja Glycine max (L.) a Nezara viridula (L. ,1758) (Hemiptera: Pentatomidae)

Visando avaliar a resistência de diferentes genótipos de soja [Glycine max (L.)] frente ao ataque do percevejo Nezara viridula (L.) (Hemiptera: Pentatomidae), foram conduzidos ensaios em laboratório sob condições controladas (T= 25  2º C, U.R.= 70  10% e fotoperíodo= 12 h). Foram realizados testes de atratividade e preferência para alimentação com grãos maduros e vagens verdes dos genótipos de soja „Conquista‟, „IAC-17‟, „IAC-19‟, „IAC-24‟, „PI-227687‟, „TMG-103‟, „TMG-117‟, „TMG-121‟, „BRS-242‟ e „IAC-PL1‟, avaliando-se o número de insetos atraídos aos 15, 30, 45, 60, 120 e 180 minutos após a liberação. No teste com vagens verdes, contou-se também o número de picadas e o tempo médio de alimentação por picada. Visando associar a preferência do inseto com as características físicas dos genótipos, realizou-se a contagem do número de tricomas em vagens verdes (densidade/área) e a medição da textura nestas mesmas vagens. Estudos de antibiose também foram realizados utilizando-se os mesmos genótipos, acompanhando-se diariamente o desenvolvimento dos insetos confinados a cada material (25 ninfas/genótipo). Nesta fase avaliou-se: a duração de cada estádio e a duração total da fase ninfal; a mortalidade por estádio e total da fase ninfal; o peso de ninfas (N5) e adultos recém-emergidos (24 h) e o período de desenvolvimento de ovo a adulto. Em teste com chance de escolha, os grãos maduros de „TMG-117‟ e „TMG-121‟ foram menos atrativos aos adultos de N. viridula. Com relação às vagens, „IAC-17‟ e „PI-227687‟ foram os menos atrativos; „IAC-17‟ e „IAC-PL1‟ foram pouco consumidos, indicando a expressão de resistência por não-preferência para alimentação. As vagens dos genótipos „IAC-17‟, „TMG-117‟ e „PI-227687‟ apresentaram elevada densidade de tricomas; em „IAC-17‟...Aiming to evaluate the resistance of different genotypes of soybean Glycine max L. against the attack of stink bug Nezara viridula (L., 1758) (Hemiptera: Pentatomidae), experiments were conducted in laboratory under controlled conditions (T= 25  2 ° C, R.H= 70  10% and photoperiod= 12 h). Tests of attractiveness and preference were conducted in mature grain and green pods of soybean genotypes „Conquista‟, „IAC-17‟, „IAC-19‟, „IAC-24‟, „PI-227687‟, „TMG-103‟, „TMG -117‟, „TMG -121‟, „BRS-242‟ and „IAC-PL1‟, evaluating the number of insects attracted to the 15, 30, 45, 60, 120 and 180 minutes after release. In the test with green pods, also counted the number of pricks and the average time of feeding per prick. Aiming to the preference of the insect with the physical characteristics of the genotypes, there was a count of the number of trichomes in green pods (density / area) and the measurement of texture in these same pods. Antibiosis studies were also conducted using the same genotypes, following the daily development of insects confined in each material (25 insects / genotype). At this stage it was evaluated: the duration of each stage and total duration of the nymphal stage; the mortality per stage and total nymphal stage; the weight of nymphs (N5) and newly emerged adults (24 h) and the development period from egg to adult. In test-choice, the mature grains of „TMG-117‟ and „TMG-121‟ were less attractive to adults of N. viridula. Regarding the pods, „IAC-17‟ and „PI-227687‟ were the least attractive, „IAC-17‟ and „IAC-PL1‟ were little consumed, indicating the expression of resistance by non-preference for feeding. The pods of the genotypes „IAC-17‟, „TMG-117‟ and „PI-227687‟ showed high density of trichomes; in „IAC-17‟ this structure was considered the main factor of resistance. In biology tests...

Feeding preference of Nezara viridula (Hemiptera: Pentatomidae) and attractiveness of soybean genotypes

Nezara viridula (L.) (Hemiptera: Pentatomidae) is a cosmopolitan insect that causes economic damages to several cultures, in particular soybeans (Glycine max [L.] Merr.) Among the techniques that involve Integrated Pest Management, the resistance of plants is pointed as a tool of great value and can contribute to the reduction of populations of insects. The feeding preferences of adults of southern green stink bug (N. viridula), and the attractiveness of soybean genotypes were evaluated under laboratory conditions to detect the most resistant material against attack from this insect. A choice test, using mature grains and green pods of the genotypes was carried out, in which the number of individuals attracted in different periods was counted. Feeding preference was evaluated in the choice tests using green pods and the number of pricks and the average time spent feeding by pricks were evaluated. In addition, texture and trichome density in the green pods were evaluated. The mature grains of 'TMG 117RR' and 'TMG 121RR' were less attractive to the adults of N. viridula. Regarding the green pods, 'IAC 17' and PI 227687 were less attractive; 'IAC 17' and 'IAC PL1' were less consumed, indicating the feeding non-preference as a resistance mechanism. 'IAC 17', 'TMG-117RR' and PI 227687 presented high levels of trichome density, and in 'IAC 17' this morphological characteristic was considered to be the main resistance factor against N. viridula. These results may be useful for breeding programs that focus on the resistance of soybeans to insects

ASSESSING Bemisia tabaci (GENN.) BIOTYPE B RESISTANCE IN SOYBEAN GENOTYPES: ANTIXENOSIS AND ANTIBIOSIS

Since it was first reported in Brazil in the 1990s, the B biotype of silverleaf whitefly (Bemisia tabaci [Genn.], Hemiptera: Aleyrodidae) has been recognized as an important pest in soybeans (Glycine max L.), reducing the productivity of this legume species in some areas of the country. As an alternative to chemical control, the use of resistant genotypes represents an important tool for integrated pest management (IPM). This study evaluated the performance of 10 soybean genotypes prior to whitefly infestation, by testing attractiveness and preference for oviposition in the greenhouse and antibiosis in the laboratory. In a multiple-choice test, 'IAC-17' was the least attractive to insects. In a no-choice test, 'IAC-17' was the least attractive for, egg deposition, indicating the occurrence of non-preference for oviposition on this genotype. Trichome density was positively correlated with the oviposition site and may be associated with the resistance of 'IAC-17' to infestation. The genotypes 'IAC-PL1', 'IAC-19', 'Conquista', 'IAC-24' and 'IAC-17' extended the insect's life cycle, indicating the occurrence of a small degree of antibiosis and/or non-preference for feeding.Sao Paulo Research Foundation - FAPESP [07/50688-8, 09/53977-6]Sao Paulo Research Foundation (FAPESP)National Council for Scientific and Technological Development - CNPqNational Council for Scientific and Technological Development (CNPq
