Reversal of angiodysplasia-derived anemia after transcatheter aortic valve implantation
SummaryAortic valve stenosis associated with angiodysplasia (Heyde's syndrome) and consequent anemia had previously been reported to benefit from surgical aortic valve replacement. In this clinical case an 89-year-old patient with chronic angiodysplasia-derived anemia, characterized by acute phases of active gastrointestinal bleeding experienced a normalization of hemoglobin values after a trans-catheter aortic valve implantation (TAVI) of a self-expandable aortic valve prosthesis (CoreValve, Medtronic Inc., Minneapolis, MN, USA). This is the first, to our knowledge, reported clinical case of remission of angiodysplasia-derived anemia after TAVI
Periprocedural Myocardial Injury and Long-Term Clinical Outcome in Patients Undergoing Percutaneous Coronary Interventions of Coronary Chronic Total Occlusion
Periprocedural myocardial injury (PMI) after percutaneous coronary intervention (PCI) might occur more frequently during challenging procedures such as PCI of chronic coronary total occlusion (CTO). The prognostic implication of PMI in CTO-PCI remains unclear
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

ACEF and clinical SYNTAX score in the risk stratification of patients with heavily calcified coronary stenosis undergoing rotational atherectomy with stent implantation
AIM: To assess ACEF (age, creatinine, and ejection fraction) and Clinical SYNTAX (CSS) score in the risk stratification of patients with heavily calcified stenosis undergoing rotational atherectomy with stent implantation (rota-stenting).
METHODS AND RESULTS: ACEF and CSS were calculated in 221 consecutive patients with stable angina undergoing rota-stenting. Mean age of the patients was 74 ± 10 years, left ventricular ejection fraction was 61 ± 18%, and final burr size 1.78 ± 0.24 mm, with 2.6 ± 0.9 burrs used for each patient. Primary end-point was MACE at one-year defined as the composite of cardiac death, myocardial infarction, and target vessel revascularization. Post-hoc analysis was performed by stratifying the clinical outcome according to ACEF and CSS tertiles. At 1 year there was a significantly higher MACE rate in the high tertile of ACEF (24% for ACEFHigh vs. 13% for ACEFMid vs. 9% for ACEFLow; P = 0.017) and CSS (25% for CSSHigh vs. 12% for CSSMid vs. 8% for CSSLow; P = 0.008). The predictive accuracy for both ACEF and CSS was moderate (c-statistics, 0.629 and 0.638, respectively).
CONCLUSION: Both ACEF and CSS predict with moderate accuracy MACE at 1-year in patients with heavily calcified coronary stenosis undergoing rotational atherectomy with stent implantatio
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
