TL;DR: C Citation patterns temporal analysis revealed a transition of the scientific interest from research focused on antioxidant vitamins and minerals into stronger attention focus on antioxidant phytochemicals (plant secondary metabolites).
Abstract: Antioxidants are abundant in natural dietary sources, and the consumption of antioxidants has a lot of potential health benefits. However, there has been no literature analysis on this topic to evaluate its scientific impact in terms of citations. This study is aimed at identifying and analysing the antioxidant publications in the existing scientific literature. In this context, a literature search was performed with the Web of Science database. Full records and cited references of the 299,602 identified manuscripts were imported into VOSviewer for bibliometric analysis. Most of the manuscripts were published since 1991. The publications were mainly related to the categories biochemistry/molecular biology, food science technology, and pharmacology/pharmacy. These topics have been prolific since 1990 and before. Polymer science was prolific before, but its publication share declined in the recent two decades. Brazil, China, India, and South Korea have emerged as upcoming major contributors besides USA. Most prolific journals were Food Chemistry, Journal of Agricultural and Food Chemistry, Free Radical Biology and Medicine, and PLOS One. Clinical conditions with high citations included Alzheimer’s disease, cancer, cardiovascular disease, and Parkinson’s disease. Chemical terms and structures with high citations included alpha-tocopherol, anthocyanin, ascorbate, beta-carotene, carotenoid, curcumin, cysteine, flavonoid, flavonol, hydrogen peroxide, kaempferol, N-acetylcysteine, nitric oxide, phenolic acid, uric acid, vitamin C, vitamin E, selenium, and resveratrol. Citation patterns temporal analysis revealed a transition of the scientific interest from research focused on antioxidant vitamins and minerals into stronger attention focus on antioxidant phytochemicals (plant secondary metabolites).

TL;DR: A comprehensive investigation into the bias and variance behavior of multistep-ahead forecasting strategies is presented and recommendations are given concerning the advantages, disadvantages, and best conditions of use of each strategy.
Abstract: Multistep-ahead forecasts can either be produced recursively by iterating a one-step-ahead time series model or directly by estimating a separate model for each forecast horizon. In addition, there are other strategies; some of them combine aspects of both aforementioned concepts. In this paper, we present a comprehensive investigation into the bias and variance behavior of multistep-ahead forecasting strategies. We provide a detailed review of the different multistep-ahead strategies. Subsequently, we perform a theoretical study that derives the bias and variance for a number of forecasting strategies. Finally, we conduct a Monte Carlo experimental study that compares and evaluates the bias and variance performance of the different strategies. From the theoretical and the simulation studies, we analyze the effect of different factors, such as the forecast horizon and the time series length, on the bias and variance components, and on the different multistep-ahead strategies. Several lessons are learned, and recommendations are given concerning the advantages, disadvantages, and best conditions of use of each strategy.

TL;DR: In this paper, the authors compared the effect of three different ablation approaches on the long-term success in patients with paroxysmal atrial fibrillation (AF) longterm freedom from AF/atrial tachyarrhythmia is unclear.
Abstract: Background— Whether different ablation strategies affect paroxysmal atrial fibrillation (AF) long-term freedom from AF/atrial tachyarrhythmia is unclear. We sought to compare the effect of 3 different ablation approaches on the long-term success in patients with paroxysmal AF.
Methods and Results— One hundred three consecutive patients with paroxysmal AF scheduled for ablation and presenting in the electrophysiology laboratory in AF were selected for this study. Patients were randomized to pulmonary vein antrum isolation (PVAI; n=35) versus biatrial ablation of the complex fractionated atrial electrograms (CFAEs; n=34) versus PVAI followed by CFAEs (n=34). Patients were given event recorders and followed up at 3, 6, 9, 12, and 15 months postablation. There was no statistical significant difference between the groups in term of sex, age, AF duration, left atrial size, and ejection fraction. At 1 year follow-up, freedom from AF/atrial tachyarrhythmia was documented in 89% of patients in the PVAI group, 91% in the PVAI plus CFAEs group, and 23% in the CFAEs group ( P <0.001) after a single procedure and with antiarrhythmic drugs.
Conclusion— No difference in terms of success rate was seen between PVAI alone and PVAI associated with defragmentation. CFAEs ablation alone had the smallest impact on AF recurrences at 1-year follow-up. These results suggest that antral isolation is sufficient to treat most patients with paroxysmal AF.
