Permanent left atrial pacing therapy may improve symptoms in heart failure patients with preserved ejection fraction and atrial dyssynchrony: a pilot…

2012

Aims Our group has recently shown that in some patients, heart failure with preserved ejection fraction (HFPEF) may be explained by ‘atrial dyssynchrony syndrome’ (ADS) due to interatrial conduction delay (IACD), a short left atrioventricular interval (LAVI), and increased left atrial (LA) stiffness. Our primary objective was to evaluate LA pacing therapy as a new treatment to restore left ventricular active filling in patients with no other known causes for HF than ADS. Methods and results Six patients with severe HFPEF with IACD (P wave duration >120 ms in lead II), short LAVI during electrophysiological studies ( 15), and no standard indication for a pacemaker were implanted with a lead …

Eresus kollari (Araneae: Eresidae) calls for heathland management

2011

Northwest Europe’s largest heather-dominated sandy habitats are located in the nature reserve Lu¨neburgerHeide, Germany. Yet, even these appear to be losing their ability to support some of their stenotopic species such as theladybird spider, Eresus kollari Rossi 1846, and are thus becoming increasingly important for the preservation of thesespecies. The habitat requirements of this endangered spider species were investigated in order to obtain data that will helpstabilize the last remnants of the species’ population in northwest Germany. Several heathland habitats were surveyed bypitfall trapping during the mate-search period of the males. Two statistical methods were applied: logistic reg…

Potential of contemporary evolution to erode fishery benefits from marine reserves

2016

Marine reserves are valued for their ecological role: protecting fish populations from overharvesting while, at the same time, potentially maintaining fisheries yields via recruitment effects (net export of pelagic eggs and larvae) and spillover (net export of post-settled juveniles and mature fish) across reserve borders. Focussing on the spillover effect, we argue that when fitness of the protected individuals depends on the relative size of their home ranges compared to the reserve size, and home range size is a property of the individuals, rapid local adaptation might occur in favour of individuals with smaller home ranges. Individuals that avoid fishing mortality by spending most of th…

1-Year Outcomes of FFRCT-Guided Care in Patients With Suspected Coronary Disease

2016

Abstract Background Coronary computed tomographic angiography (CTA) plus estimation of fractional flow reserve using CTA (FFR CT ) safely and effectively guides initial care over 90 days in patients with stable chest pain. Longer-term outcomes are unknown. Objectives The study sought to determine the 1-year clinical, economic, and quality-of-life (QOL) outcomes of using FFR CT instead of usual care. Methods Consecutive patients with stable, new onset chest pain were managed by either usual testing (n = 287) or CTA (n = 297) with selective FFR CT (submitted in 201, analyzed in 177); 581 of 584 (99.5%) completed 1-year follow-up. Endpoints were adjudicated major adverse cardiac events (MACE) …

Burden of Recurrent Hospitalizations Following an Admission for Acute Heart Failure: Preserved Versus Reduced Ejection Fraction.

2017

Abstract Introduction and objectives Heart failure with preserved ejection fraction and reduced ejection fraction share a high mortality risk. However, differences in the rehospitalization burden over time between these 2 entities remains unclear. Methods We prospectively included 2013 consecutive patients discharged for acute heart failure. Of these, 1082 (53.7%) had heart failure with preserved ejection fraction and 931 (46.2%) had heart failure with reduced ejection fraction. Cox and negative binomial regression methods were used to evaluate the risks of death and repeat hospitalizations, respectively. Results At a median follow-up of 2.36 years (interquartile range: 0.96-4.65), 1018 pat…

Aesthetics of Nutrition, Ethics of Animality: the Packaging of Vegan and Vegetarian Products in the Italian Organised Distribution Market

2018

The topic of this paper concerns the packaging of vegan and vegetarian products in the Italian organised distribution market. Large-scale organised distribution and vegetarianism's choice of packaging is related to current dietary trends which, as is often the case with eating choices and habits, intertwine as they massively spread. Which are the visual and verbal strategies that are adopted to give meaning, in the Italian culinary landscape, to vegan and vegetarian foods sold through large-scale distribution? The aim is to outline, through the methodology of Semiotics, the sensorial mechanisms and cultural grids that shape this food universe, and the way it interacts with other categories …

Heart rate response and functional capacity in patients with chronic heart failure with preserved ejection fraction

2018

Aims The mechanisms of exercise intolerance in heart failure with preserved ejection fraction (HFpEF) are not yet elucidated. Chronotropic incompetence has emerged as a potential mechanism. We aimed to evaluate whether heart rate (HR) response to exercise is associated to functional capacity in patients with symptomatic HFpEF. Methods and results We prospectively studied 74 HFpEF patients [35.1% New York Heart Association Class III, 53% female, age (mean ± standard deviation) 72.5 ± 9.1 years, and 59.5% atrial fibrillation]. Functional performance was assessed by peak oxygen consumption (peak VO2 ). The mean (standard deviation) peak VO2 was 10 ± 2.8 mL/min/kg. The following chronotropic pa…

Autologous stem cell ovarian transplantation to increase reproductive potential in patients who are poor responders.

2018

Objective: To evaluate effects of autologous stem cell ovarian transplant (ASCOT) on ovarian reserve and IVF outcomes of women who arc poor responders with very poor prognosis. Design: Prospective observational pilot study. Setting: University hospital. Patient(s): Seventeen women who are poor responders. Intervention(s): Ovarian infusion of bone marrow-derived stem cells. Main Outcome Measure(s): Serum antimullerian hormone levels and antral follicular count (AFC), punctured follicles, and oocytes retrieved after stimulation (controlled ovarian stimulation) were measred. Apheresis was analyzed for growth factor concentrations. Result(s): The ASCOT resulted in a significant improvement in A…
