The International Study of Asthma and Allergies in Childhood (ISAAC) Phase Three: A global synthesis

2013

This ISAAC Phase Three synthesis provides summarised information on the main findings of the study, regional tables and figures related to the prevalence and severity of current symptoms of asthma, rhinoconjunctivitis and eczema in the main regions of the world. The large number of surveyed children (≈1,200,000), the large number of centres (233) and countries (98) that participated in ISAAC Phase Three makes this study the most comprehensive survey of these diseases ever undertaken. Globally, the prevalence for current asthma, rhinoconjunctivitis and eczema in the 13-14-year age group was 14.1%, 14.6% and 7.3%, respectively. In the 6-7-year age group the prevalence for current asthma, rhin…

Phenotypes of COPD patients with a smoking history in Central and Eastern Europe: the POPE Study.

2017

Chronic obstructive pulmonary disease (COPD) represents a major health problem in Central and Eastern European (CEE) countries; however, there are no data regarding clinical phenotypes of these patients in this region.Participation in the Phenotypes of COPD in Central and Eastern Europe (POPE) study was offered to stable patients with COPD in a real-life setting. The primary aim of this study was to assess the prevalence of phenotypes according to predefined criteria. Secondary aims included analysis of differences in symptom load, comorbidities and pharmacological treatment.3362 patients with COPD were recruited in 10 CEE countries. 63% of the population were nonexacerbators, 20.4% frequen…

Survival and reinterventions after isolated proximal aortic repair in acute type A aortic dissection.

2018

OBJECTIVES Conventional treatment for acute type A dissection is the replacement of the ascending aorta. This study demonstrates the results of a conventional approach with isolated proximal repair combined with concomitant endovascular procedures. METHODS Replacement of the ascending aorta with or without an open distal anastomosis was defined as isolated proximal repair and was performed in 562/588 patients between January 2004 and June 2017. A total of 68% were DeBakey type I and 32% were DeBakey type II aortic dissections. Concomitant procedures were thoracic endovascular aortic repair (3.6%); visceral, renal and iliac stents (2%); and peripheral bypasses (1.1%). Mean follow-up was 4.6 …

External reinforcement of varicose veins with PTFE prosthesis in infrainguinal bypass surgery -- clinical results.

2003

OBJECTIVE Segmental varicose degeneration of the autogenous greater saphenous vein may limit its use in infrainguinal bypass surgery. Wrapping a PTFE prosthesis around dilated veins has emerged as an option to create externally reinforced vein bypasses. Results regarding graft patency and limb salvage were analyzed. METHODS Between September 1995 and January 2001, 35 infrainguinal bypass operations in 33 patients were performed with greater saphenous veins exhibiting segmental varicose dilatation. Grafts were followed by duplex scan and retrospective analysis of graft patency and limb salvage was performed. RESULTS One bypass prompted successful revision for early occlusion. Four bypasses r…

Doing Science: Peer reviewing

2014

External peer review is a hallmark of science. “Published in a peer-reviewed journal” is a sign of quality, meaning that the work has been scrutinised by knowledgeable and independent peers. Moreover, peer review also serves the purpose of improving the work after the authors have done their best and, thus, being a reviewer carries a responsibility. However, it comes with little reward; reviewing is usually done without financial compensation and often outside of work hours. But reviewing is rewarding in itself! Besides being pro bono , it exposes you, as a reviewer, to novel findings and adds a new perspective to your own research and scientific writing. And you can add “Peer reviewer for …

The Neochord Procedure After Failed Surgical Mitral Valve Repair.

2021

Surgical mitral valve reintervention is associated with significant morbidity and mortality, and repeat repair is not always feasible. We examine the clinical outcomes of the NeoChord procedure after failed conventional mitral valve repair. A total of 312 patients were treated with the NeoChord repair procedure between January 2014 and December 2018 at 5 European centers. Clinical and echocardiographic data were reviewed to identify patients who had a prior surgical mitral valve repair procedure. The primary endpoint (Patient Success) was a composite of placement of at least 2 neochordae and end-procedure mitral valve regurgitation (MR) ≤ mild, freedom from death, stroke, structural or func…

Worldwide production on sleep apnea from 2009–2018. Analysis of the ability to secure funding and international collaboration networks

2021

[Background]: Obstructive sleep apnea (OSA) is an emerging health problem, but information on scientific production in this subject area is scarce. We aim to evaluate the scientific production on OSA from 2009 to 2018 to illustrate its worldwide distribution, topic areas, and ability to secure funding, as well as to describe international collaboration networks in this field. [Methods]: Articles published between 2009 and 2018 were extracted from the Science Citation Index Expanded via Web of Science (WoS) using the search term “obstructive sleep apn*“. Publication year, number and country of authors, journal, subject category, key words, funding source and number of citations received were…

Defining moderate asthma exacerbations in clinical trials based on ATS/ERS joint statement

2015

Background Exacerbations are a key outcome in clinical research, providing patient-relevant information about symptomatic control, health state and disease progression. Generally considered as an episode of (sub)acute deterioration of respiratory symptoms, a precise, clinically useful definition is needed for use in clinical trials. Aim and methods Focussing on moderate exacerbations, this opinion piece reviews landmark trials and current guidelines to provide a practical definition of a moderate exacerbation. Specifically, we adapt the ATS/ERS consensus statement of terminology Reddel et al. (2009) [1] which provides a conceptual (or 'theoretical') definition for moderate exacerbations, to…

phi-Best proximity point theorems and applications to variational inequality problems

2017

The main concern of this study is to introduce the notion of $$\varphi $$ -best proximity points and establish the existence and uniqueness of $$\varphi $$ -best proximity point for non-self mappings satisfying $$(F,\varphi )$$ -proximal and $$(F,\varphi )$$ -weak proximal contraction conditions in the context of complete metric spaces. Some examples are supplied to support the usability of our results. As applications of the obtained results, some new best proximity point results in partial metric spaces are presented. Furthermore, sufficient conditions to ensure the existence of a unique solution for a variational inequality problem are also discussed.
