Current status and needs for changes in critical care training: the voice of the young cardiologists
2020
Abstract Aims The implementation of the 2013 European Society of Cardiology (ESC) Core Curriculum guidelines for acute cardiovascular care (acc) training among European countries is unknown. We aimed to evaluate the current status of acc training among cardiology trainees and young cardiologists (<40 years) from ESC countries. Methods and results The survey (March–July 2019) asked about details of cardiology training, self-confidence in acc technical and non-technical skills, access to training opportunities, and needs for further training in the field. Overall 614 young doctors, 31 (26–43) years old, 55% males were surveyed. Place and duration of acc training differed between countr…
Biomechanical Determinants of Right Ventricular Failure in Pulmonary Hypertension.
2018
Pulmonary hypertension (PH) is a disease characterized by progressive adverse remodeling of the distal pulmonary arteries, resulting in elevated pulmonary vascular resistance and load pressure on the right ventricle (RV), ultimately leading to RV failure. Invasive hemodynamic testing is the gold standard for diagnosing PH and guiding patient therapy. We hypothesized that lumped-parameter and biventricular finite-element (FE) modeling may lead to noninvasive predictions of both PH-related hemodynamic and biomechanical parameters that induce PH. We created patient-specific biventricular FE models that characterize the biomechanical response of the heart and coupled them with a lumped-paramete…
Declining exposures to lead and cadmium contribute to explaining the reduction of cardiovascular mortality in the US population, 1988-2004.
2017
Background Lead and cadmium exposures have markedly declined in the USA following the implementation of large-scale public health policies and could have contributed to the unexplained decline in cardiovascular mortality in US adults. We evaluated the potential contribution of lead and cadmium exposure reductions to explain decreasing cardiovascular mortality trends occurring in the USA from 1988-94 to 1999-2004. Methods Prospective study in 15 421 adults ≥40 years old who had participated in the National Health and Nutrition Examination Survey 1988-94 or 1999-2004. We estimated the amount of change in cardiovascular mortality over time that can be independently attributed to the intermedia…
Implantation Strategy of the Atrial Dipole Impacts Atrial Sensing Performance of Single Lead VDD Pacemakers
2002
WIEGAND, U.K.H., et al.: Implantation Strategy of the Atrial Dipole Impacts Atrial Sensing Perfor-mance of Single Lead VDD Pacemakers. Intermittent atrial undersensing is observed in a considerable percentage of patients with single lead VDD pacemakers. Analyzing the 2-year data of the Saphir Multicenter Follow-Up Study, the authors investigated predictors for the occurrence of undersensing. The study included 194 patients with high degree AV block who received a VDD pacemaker system with an identical sensing amplifier. Placement strategy of the atrial dipole was left to the discretion of the implanting physician. At the final position, atrial potential amplitudes were measured during deep …
Use of Visual Feedback During Jump-Squat Training Aids Improvement in Sport-Specific Tests in Athletes.
2020
Vanderka, M, Bezak, A, Longova, K, Krcmar, M, and Walker, S. Use of visual feedback during jump-squat training aids improvement in sport-specific tests in athletes. J Strength Cond Res 34(8): 2250-2257, 2020-This study investigated the effects of instantaneous performance feedback during the jump-squat exercise over a 6-week training period. Twenty-five strength-trained athletes were randomly divided into an instant feedback (n = 13, half-squat 3-repetition maximum (3RM)/body mass = 2.38 ± 0.19) or a nonfeedback (n = 12, half-squat 3RM/body mass = 2.03 ± 0.44) group. Both groups performed the same training program (3 × week), consisting of 4 sets of 8 repetitions (weeks 1-3) and 8 sets of 4…
Lead-Related Infective Endocarditis in Latvia: A Single Centre Experience
2019
Background and Objectives: Over the last five decades cardiac implantable electronic devices (CIED) have become established as the mainstay for the treatment of permanent bradycardias, chronic heart failure and dangerous heart rhythm disturbances. These devices improve survival and quality of life in many patients. However, infections associated with CIED implantation, particularly lead-related infective endocarditis (LRIE), can offset all benefits and make more harm than good for the patient. To date, there are no other studies in Latvia, addressing patients with lead-related infective endocarditis. The objective of this study was to identify the most common pathogens associated with LRIE …
Links between maternal feeding practices and children's eating difficulties. Validation of French tools
2012
Abstract: The main objectives of the study were to validate a measure of young children's eating difficulties and maternal feeding practices in a French sample, and to assess the links between these practices and children's eating difficulties. Mothers of French children aged 20-36 months completed 4 questionnaires that were validated using a Structural Equation Modelling approach. Links between children and maternal components were investigated using a PLS regression. The Children's Eating Difficulties Questionnaire yielded a 4-dimension solution: Neophobia, Pickiness, Low Appetite and Low Enjoyment in food. The Feeding Style Questionnaire assessed 3 dimensions: Authoritarian, Authoritativ…
Prenatal exposure to lead in Spain: Cord blood levels and associated factors
2011
Abstract Introduction and Objective Lead is a known neurotoxic. Fetuses and infants are very vulnerable to lead exposure, since their blood-brain barrier is not completely formed. Hence, there is an importance for monitoring of blood lead levels prenatally and during early infancy. The aim of this study is to evaluate the prenatal exposure to lead and its association with maternal factors in four population based mother–child cohorts in Spain. The present research was carried out within the framework of the INMA project INfancia y Medio Ambiente (Environment and Childhood). Methods A total of 1462 pregnant women were recruited between 2004 and 2008. Lead was analyzed in a sample of cord blo…
Transitional care of young people with juvenile idiopathic arthritis in Italy: results of a Delphi consensus survey
2018
OBJECTIVES: To present the results of a Delphi consensus survey among Italian paediatric and adult rheumatologists on transitional care (TC) of young people (YP) with juvenile idiopathic arthritis (JIA). METHODS: A taskforce of 27 paediatric and adult rheumatologists evaluated the applicability of the 2016 EULAR/PReS recommendations for TC to the Italian rheumatology practice and healthcare system and formulated additional country-specific statements aimed to increase their suitability. After a two-round discussion, applicability of EULAR/PReS recommendations and agreement with newly-proposed statements were voted on a 0-10 scale (where 0 = no applicability/agreement and 10 = total applicab…
An unusual case of sudden cardiac death during sexual intercourse
2018
The most common cause of sudden death during sexual intercourse in adults is heart disease, and it is usually the male, whereas the death of the woman is unusual. Generally, in these cases, death occurs as a result of cardiovascular disease. The authors report an unusual case of the sudden death of a young woman during sexual intercourse. The post-mortem investigations (autopsy, cardiac nuclear magnetic resonance and cardiac histology) demonstrated a previously undiagnosed arrhythmogenic right ventricular cardiomyopathy. The terminal cause of death was a malignant arrhythmia from arrhythmogenic right ventricular cardiomyopathy. This is the first report of a case in which sexual activity ca…
