The Short Physical Performance Battery does not correlate with daily life gait quality and quantity in community-dwelling older adults with an increased fall risk.

Background: Both the Short Physical Performance Battery (SPPB) and daily life gait quality and quantity obtained from wearable sensors are used to measure functional status in older adults. It is generally assumed that they are interrelated and exchangeable, but this has not yet been established. Interchangeability of these measures would pave the way for remote monitoring of functional status.

Optimizing and Implementing a Community-Based Group Fall Prevention Program: A Mixed Methods Study.

Falls and fall-related injuries among older adults are associated with decreased health. Therefore, fall prevention programs (FPPs) are increasingly important. However, the translation of such complex programs into clinical practice lacks insight into factors that influence implementation.

Treatment of severe symptomatic aortic valve stenosis using non-invasive ultrasound therapy: a cohort study.

Background: Calcific aortic stenosis is commonly treated using surgical or transcatheter aortic valve replacement; however, many patients are not considered suitable candidates for these interventions due to severe comorbidities and limited life expectancy. As such, non-invasive therapies might offer alternative therapeutic possibilities in these patients. This study aimed to assess the safety of non-invasive ultrasound therapy and its ability to improve valvular function by softening calcified valve tissue.

Assessing the Novel Myval Balloon-Expandable Valve with the Evolut Valve: A Propensity-Matched Study.

Background: The Myval balloon-expandable (BE) valve has shown encouraging early clinical data in terms of safety and efficacy. Comparative data with other well-established contemporary valves are nonetheless still scarce. This study aims to compare the performance of the Myval BE valve with the Evolut self-expanding (SE) valve.

Physical activity as a risk or protective factor for falls and fall-related fractures in non-frail and frail older adults: a longitudinal study.

Background: Physical activity may be both a risk and protective factor for falls and fall-related fractures. Despite its positive effects on muscle and bone health, physical activity also increases exposure to situations where falls and fractures occur. This paradox could possibly be explained by frailty status.

Impact of thrombus burden on long-term clinical outcomes in patients with either anterior or non-anterior ST-segment elevation myocardial infarction.

Large thrombus burden (LTB) during ST-segment elevation myocardial infarction (STEMI) could translate into worse clinical outcomes. The impact of a LTB in terms of long-term clinical outcomes on different myocardial infarct territories has not yet been fully evaluated. From April 2002 to December 2004, consecutive patients with STEMI undergoing percutaneous coronary intervention with drug eluting stent were evaluated.

Impact of Large Thrombus Burden on Very Long-Term Clinical Outcomes in Patients Presenting With ST-Segment Elevation Myocardial Infarction.

Objectives: The impact of large thrombus burden (LTB) on very long-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) is unknown. We compared very long-term clinical outcomes in STEMI patients with either LTB or small thrombus burden (STB).

Methods: Between 2002 and 2004, thrombus burden (TB) was evaluated in consecutive patients with STEMI undergoing percutaneous coronary intervention (PCI).

Use of Lithotripsy in a Calcified Saphenous Vein Graft.

Percutaneous coronary interventions in saphenous vein grafts can pose a variety of challenges, such as severely calcified lesions. If these lesions are nondilatable, lithotripsy can arguably be a proper tool for lesion preparation. We present a case in which a nondilatable, calcified saphenous vein graft was successfully treated using Shockwave lithotripsy.

The (cost-)effectiveness of an implemented fall prevention intervention on falls and fall-related injuries among community-dwelling older adults with an increased risk of falls: protocol for the in balance randomized controlled trial.

Background: Falls and fall-related injuries among older adults are a serious threat to the quality of life and result in high healthcare and societal costs. Despite evidence that falls can be prevented by fall prevention programmes, practical barriers may challenge the implementation of these programmes. In this study, we will investigate the effectiveness and cost-effectiveness of In Balance, a fourteen-week, low-cost group fall prevention intervention, that is widely implemented in community-dwelling older adults with an increased fall risk in the Netherlands.

A case report: adenosine triggered myocardial infarction during myocardial perfusion stress test imaging in a diabetic patient.

Background: Myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) can in general be used safely in daily clinical practice. However, under the right circumstances, it can lead to serious complications.

Case Summary: A 68-year-old female patient with diabetes and a history of inferior ST-elevation myocardial infarction 8 years earlier, visited our outpatient clinic with atypical chest discomfort.

Clinical Management of Duchenne Muscular Dystrophy in the Netherlands: Barriers to and Proposals for the Implementation of the International Clinical Practice Guidelines.

Background: In order to successfully implement the international clinical care guidelines for Duchenne muscular dystrophy (DMD) in the Netherlands, it is essential to know what barriers are experienced by healthcare practitioners regarding guideline adherence and organization of care. In the Netherlands, academic medical centers provide follow up visits and work together with peripheral hospitals, rehabilitation centers, centers for home ventilation and primary care centers for treatment.

Objective: To investigate perceived barriers to international clinical DMD guideline adherence and identify potential areas of improvement for implementation in the Dutch 'shared care' organization.

An update on the use of anticoagulant therapy in ST-segment elevation myocardial infarction.

Introduction: Together with antiplatelet therapy, anticoagulants are vital to improve outcomes in patients presenting with ST-segment elevation myocardial infarction. Challenges lie in finding the optimal balance between the risk of bleeding and preventing thrombotic complications such as reinfarction or stent thrombosis. During the last decade, bivalirudin was introduced as a valid alternative to heparin for patients undergoing primary percutaneous coronary intervention.

Effectiveness of adherence to a preoperative antiplatelet and anticoagulation cessation protocol in cardiac surgery.

Objectives: Reduction of blood loss after cardiac surgery remains challenging. The effectiveness of adherence to a protocol on cessation of anticoagulants and platelet-inhibiting medications was investigated together with the influence of protocol violations on blood loss after surgery, use of blood products, surgical re-explorations and 30-day mortality.

Methods: Between 2009 and 2013, data were collected prospectively for all elective cardiac surgery procedures in adult patients (n = 1637).

Risk stratification for adult congenital heart surgery.

Objective: At this moment, no risk stratification models are available for adult congenital cardiac surgery. This study aims to identify a suitable stratification tool for the adult congenital heart surgery population. Pediatric congenital cardiac surgery score models were therefore tested in an adult congenital population.

Validation of a prognostic model to predict survival after non-small-cell lung cancer surgery.

Objective: Surgery is the first choice of treatment for localised non-small-cell lung cancer (NSCLC). When making decisions regarding resection, physicians must balance the potential long-term benefits of surgery with the risk of surgery-related death, particularly among elderly patients with multiple co-morbid conditions. In 2005, a predictive model with a preoperative and a postoperative mode to predict survival of an individual patient after NSCLC surgery was created.

Relationship between the logistic EuroSCORE and the Society of Thoracic Surgeons Predicted Risk of Mortality score in patients implanted with the CoreValve ReValving system--a Bern-Rotterdam Study.

Background: Surgical risk scores, such as the logistic EuroSCORE (LES) and Society of Thoracic Surgeons Predicted Risk of Mortality (STS) score, are commonly used to identify high-risk or "inoperable" patients for transcatheter aortic valve implantation (TAVI). In Europe, the LES plays an important role in selecting patients for implantation with the Medtronic CoreValve System. What is less clear, however, is the role of the STS score of these patients and the relationship between the LES and STS.

A comparison of patient characteristics and 30-day mortality outcomes after transcatheter aortic valve implantation and surgical aortic valve replacement for the treatment of aortic stenosis: a two-centre study.

Aims: It is unclear whether transcatheter aortic valve implantation (TAVI) addresses an unmet clinical need for those currently rejected for surgical aortic valve replacement (SAVR) and whether there is a subgroup of high-risk patients benefiting more from TAVI compared to SAVR. In this two-centre, prospective cohort study, we compared baseline characteristics and 30-day mortality between TAVI and SAVR in consecutive patients undergoing invasive treatment for aortic stenosis.

Methods And Results: We pre-specified different adjustment methods to examine the effect of TAVI as compared with SAVR on overall 30-day mortality: crude univariable logistic regression analysis, multivariable analysis adjusted for baseline characteristics, analysis adjusted for propensity scores, propensity score matched analysis, and weighted analysis using the inverse probability of treatment (IPT) as weights.

Impact of the definition of renal dysfunction on EuroSCORE performance.

Aim: Renal dysfunction is an important variable in the EuroSCORE (European System for Cardiac Operative Risk Evaluation) model and is currently defined as creatinine >200 mmol/L. The aim of this study was to examine whether using other definitions of renal dysfunction could improve the predictive ability of the EuroSCORE.

Methods: Between January 2004 and January 2006, 1 205 patients underwent cardiac surgery.

Outcome after reoperation for atrioventricular septal defect repair.

Results of surgical repair of atrioventricular septal defect (AVSD), both partial (PAVSD) and complete (CAVSD), have improved. However, reoperation is not uncommon. This report describes our experience in 59 patients who underwent reoperation after AVSD repair, between 1977 and 2008.

Complexity of coronary vasculature predicts outcome of surgery for left main disease.

Background: The SYNTAX score, a comprehensive angiographic scoring system, was recently developed as a tool for risk stratification during the SYNTAX trial (randomized trial comparing coronary artery bypass grafting with percutaneous coronary intervention). We applied the SYNTAX score in patients with left main coronary artery disease who underwent coronary artery bypass grafting to examine its role in predicting incidences of major adverse cardiac and cerebrovascular events (MACCE) within 30 days and 1 year.

Methods: One hundred forty-eight patients were studied.

Therapeutic decisions for patients with symptomatic severe aortic stenosis: room for improvement?

Objective: Symptomatic severe aortic stenosis is an indication for aortic valve replacement. Some patients are denied intervention. This study provides insight into the proportion of conservatively treated patients and into the reasons why conservative treatment is chosen.
