Geographical and temporal distribution of SARS-CoV-2 clades in the WHO European Region, January to June 2020

We show the distribution of SARS-CoV-2 genetic clades over time and between countries and outline potential genomic surveillance objectives. We applied three available genomic nomenclature systems for SARS-CoV-2 to all sequence data from the WHO European Region available during the COVID-19 pandemic until 10 July 2020. We highlight the importance of real-time sequencing and data dissemination in a pandemic situation. We provide a comparison of the nomenclatures and lay a foundation for future European genomic surveillance of SARS-CoV-2.Peer reviewe

Avaliação do impacto da suplementação alimentar a gestantes no cotrole do baixo peso ao nascer no município de São Paulo, SP (Brasil)

A partir de estudo realizado em oito grandes maternidades do Município de São Paulo, SP (Brasil) que atendem clientela predominantemente de baixo nível sócio-econômico, objetivou-se analisar o impacto da suplementação alimentar durante a assistência pré-natal sobre a incidência de recém-nascidos de baixo peso ao nascer (peso < 2.500 g). Foram envolvidos no estudo 1.060 recém-nascidos de mães que receberam suplementação e 664 recém-nascidos de mães que não a receberam. Ã incidência de baixo peso ao nascer foi de cerca de 11%, considerada elevada e semelhante em ambos os grupos de recém-nascidos. A análise multivariada, realizada para controlar eventuais diferenças entre os grupos, que não a condição de suplementação, descartou qualquer associação significativa entre suplementação e peso ao nascer e revelou, por outro lado, que tabagismo e morbidade na gestação e determinadas características antropométricas e reprodutivas da mãe, prévias à gestação, são importantes fatores de risco para o baixo peso ao nascer. A aparente explicação para a ausência de impacto da suplementação alimentar na população estudada parece residir não na quantidade insuficiente da suplementação alimentar oferecida (370 Kcal/dia), mas no predomínio de fatores não alimentares na determinação do baixo peso ao nascer. São formuladas recomendações quanto ao controle do baixo peso ao nascer no contexto estudado

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.
