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.

Determination of organochlorine pesticide residues in honey from the central zone of Portugal and the Valencian community of Spain

In this study nine organochlorine pesticide residues ([alpha]-, [beta]-, and [gamma]-hexachlorocyclohexane (HCH), hexachlorobenzene (HCB), aldrin, p,p'-DDE, p,p'-DDD, o,p'-DDT, and p,p'-DDT) in forty nine samples of honey collected from markets of Portugal and Spain during 2001 and 2002, respectively, were evaluated. For this evaluation, three analytical procedures were studied. The analytical procedure, based on LLE extraction with ethyl acetate followed by gas chromatography-electron-capture detection (GC-ECD) for quantification, and mass spectrometry (GC-MS) for confirmation, has been selected. Recoveries of spiked samples ranged from 68%, for [beta]-HCH, and 126% for p,p'-DDT, for fortification levels between 10 and 100 [mu]g/kg, and 64%, for [alpha]-HCH, and 143% for [gamma]-HCH for fortification levels between 20 and 200 [mu]g/kg. Limits of quantification, using GC-ECD, were from 0.01 and 0.10 mg/kg, and limits of detection between 0.001 and 0.02 mg/kg. Fourteen Valencian samples were contaminated, containing residues of HCB or/and HCH isomers. The frequency of detection was 56% for Spanish samples. In Portugal, 23 samples were contaminated, what means 95.8%. In Spanish samples, concentrations range from nd to 0.03 mg/kg for HCB, and nd to 2.24 mg/kg for HCH-total. The mean concentration and standard deviation were 0.017 ± 0.011 mg/kg for HCB, and 0.579 ± 0.747 mg/kg for HCH-total, contributing the [gamma] isomer with the highest values. The samples from Portugal showed higher levels. Levels of HCB ranged from nd to 0.39 mg/kg. HCH-total ranged from nd to 4.86 mg/kg, and DDT-total from nd to 0.658 mg/kg. Mean concentration and standard deviation were 0.09 ± 0.116 mg/kg for HCB, 1.357 ± 1.30 mg/kg for HCH-total, and 0.143 ± 0.193 mg/kg for DDT-total.http://www.sciencedirect.com/science/article/B6TG8-4D75MJM-2/1/228ba9bcfae0d95d011e1a86b66f79d

Sperm morphology of the Prorops nasuta (Waterston, 1923) (Hymenoptera: Bethylidae)

In the present study, spermatozoa of the Prorops nasuta (Hymenoptera: Bethylidae) parasitoid were described morphologically. This is the first publication to describe a species belonging to the superfamily Chrysidoidea. Light and transmission electron microscopy were used. The spermatozoa of P. nasuta are linear, with a mean length of 665 μm. The acrosome is composed of an acrosomal vesicle and a perforatorium. The nucleus measures approximately 17 μm in length and is circular at its cross-section; however, its anterior extremity is oval. The chromatin is electron-dense and compact, although there are clear areas in the posterior peripheral regions. In the nucleus-flagellum transition region, the cross-section of the centriole adjunct is oval, with a pleated border and an E-PTA-positive peripheral region. The axoneme shows a 9 + 9 + 2 microtubule arrangement. The microtubules are E-PTA positive and, at the posterior extremity, the accessories are the last to terminate. The diameters and shapes of the two mitochondrial derivatives are almost identical. One begins beside the nuclear base and the other after the centriole adjunct. Posteriorly, they terminate together, immediately before the axoneme. Both have mitochondrial cristae and a region of paracrystalline material; however, the format and arrangement of this material differs from those of all other species previously studied. The paracrystalline material is more strongly E-PTA positive than the cristae region. Accessories bodies are electron-dense and located between the mitochondrial derivatives and the axoneme. In general, P. nasuta spermatozoa are similar to those of the majority of Hymenoptera; however, they have various exclusive characteristics that may be useful for studying the phylogeny and taxonomy of the superfamily Chrysidoidea and of Hymenoptera in general

Occurrence of fumonisins B1 and B2 in broa, typical Portuguese maize bread

Fumonisin B1 (FB1) and fumonisin B2 (FB2) are mycotoxins mainly produced by Fusarium verticillioides, and Fusarium proliferatum, fungi species most commonly isolated from maize. The natural occurrence of FB1 and FB2 in broa, typical Portuguese maize bread, was evaluated in 30 samples. Twenty five were found positive with levels ranging from 142 to 550 [mu]g kg- 1. The limit established by the European regulations was exceeded by 27% of the samples. The tolerable daily intake for fumonisin B1, and B2, alone or in combination, for all of the analysed samples, was lower than 2 [mu]g kg- 1 body weight per day established by the European Commission.http://www.sciencedirect.com/science/article/B6T7K-4NWCGR3-1/1/44ccb945578af81739ce44d304eb96d

Ochratoxin A in the morning and afternoon portions of urine from Coimbra and Valencian populations

The widespread contamination of foodstuffs and beverages by mycotoxins, such as ochratoxin A (OTA), has made the monitoring of human contamination levels essential.http://www.sciencedirect.com/science/article/B6TCS-4RY6WKJ-1/1/4c16511b1a2109e4107233b7f0e3b98
