[Pericardial and myocardial involvement after SARS-CoV-2 infection: a cross-sectional descriptive study in healthcare workers]. / Afección pericárdica y miocárdica tras infección por SARS-CoV-2: estudio descriptivo transversal en trabajadores sanitarios.

Introduction and objectives: The cardiac sequelae of SARS-CoV-2 infection are still poorly documented. We conducted a cross-sectional study in healthcare workers to report evidence of pericardial and myocardial involvement after SARS-CoV-2 infection. Methods: We studied 139 healthcare workers with confirmed past SARS-CoV-2 infection. Participants underwent clinical assessment, electrocardiography, and laboratory tests, including immune cell profiling and cardiac magnetic resonance (CMR). Clinically suspected pericarditis was diagnosed when classic criteria were present and clinically suspected myocarditis was based on the combination of at least 2 CMR criteria. Results: Median age was 52 (41-57) years, 71.9% were women, and 16.5% were previously hospitalized for COVID-19 pneumonia. On examination (10.4 [9.3-11.0] weeks after infection-like symptoms), participants showed hemodynamic stability. Chest pain, dyspnea or palpitations were present in 41.7% participants, electrocardiographic abnormalities in 49.6%, NT-proBNP elevation in 7.9%, troponin in 0.7%, and CMR abnormalities in 60.4%. A total of 30.9% participants met criteria for either pericarditis and/or myocarditis: isolated pericarditis was diagnosed in 5.8%, myopericarditis in 7.9%, and isolated myocarditis in 17.3%. Most participants (73.2%) showed altered immune cell counts in blood, particularly decreased eosinophil (27.3%; P < .001) and increased cytotoxic T cell numbers (17.3%; P < .001). Clinically suspected pericarditis was associated (P < .005) with particularly elevated cytotoxic T cells and decreased eosinophil counts, while participants diagnosed with clinically suspected myopericarditis or myocarditis had lower (P < .05) neutrophil counts, natural killer-cells, and plasma cells. Conclusions: Pericardial and myocardial involvement with clinical stability are frequent after SARS-CoV-2 infection and are associated with specific immune cell profiles.Full English text available from:www.revespcardiol.org/en.

Predictors of cardiovascular events and all-cause of death in patients with transfusion-dependent myelodysplastic syndrome.

Cardiovascular disease (CVD) involves the second cause of death in low-risk myelodysplastic syndrome (MDS) population. Prospective study to characterise the CVD and to identify predictors for the combined event (CE) cardiovascular event and/or all-cause mortality in transfusion dependent low-risk MDS patients. Thirty-one patients underwent a cardiac assessment including biomarkers and cardiac magnetic resonance (cMR) with parametric sequences (T1, T2 and T2* mapping) and myocardial deformation by feature tracking (FT) and were analysed for clonal hematopoiesis of indeterminate potential mutations. Cardiac assessment revealed high prevalence of unknown structural heart disease (51% cMR pathological findings). After 2·2 [0·44] years follow-up, 35·5% of patients suffered the CE: 16% death, 29% cardiovascular event. At multivariate analysis elevated NT-proBNP ≥ 486pg/ml (HR 96·7; 95%-CI 1·135-8243; P = 0·044), reduced native T1 time < 983ms (HR 44·8; 95%-CI 1·235-1623; P = 0·038) and higher left ventricular global longitudinal strain (LV-GLS) (HR 0·4; 95%-CI 0·196-0·973; P = 0·043) showed an independent prognostic value. These variables, together with the myocardial T2* time < 20ms, showed an additive prognostic value (Log Rank: 12·4; P = 0·001). In conclusion, low-risk MDS patients frequently suffer CVD. NT-proBNP value, native T1 relaxation time and longitudinal strain by FT are independent predictors of poor cardiovascular prognosis, thus, their determination would identify high-risk patients who could benefit from a cardiac treatment and follow-up.

The SUMAMOS EXCELENCIA Project.

AIM: The gap between research and clinical practice leads to inconsistent decision-making and clinical audits are an effective way of improving the implementation of best practice. Our aim is to assess the effectiveness of a model that implements evidence-based recommendations for patient outcomes and healthcare quality. DESIGN: National quasi-experimental, multicentre, before and after study. METHODS: This study focuses on patients attending primary care and hospital care units and associated socio-healthcare services. It uses the Joanna Brigg's Institute Getting Research into Practice model, which improves processes by referring to prior baseline clinical audits. The variables are process and outcome criteria for pain, urinary incontinence, and fall prevention, with data collection at baseline and key points over 12 months drawn from clinical histories and records. Project funding was received from the Spanish Strategic Health Action in November 2014. DISCUSSION: The project results will provide knowledge on the effectiveness of the Getting Research into Practice model, to apply evidence-based recommendations for the detection and management of pain, urinary incontinence, and fall prevention. It will also establish whether using research results, based on clinical audits and situation analysis, is effective for implementing evidence-based recommendations and improving patients' health. IMPACT: This nationwide Spanish project aims to detect and prevent high-prevalence healthcare problems, namely pain in patients at any age and falls and urinary incontinence in people aged 65 and over. Tailoring clinical practice to evidence-based recommendations will reduce unjustified clinical variations in providing healthcare services. Clinical Trial ID: NCT03725774.

SALMANTICOR study. Rationale and design of a population-based study to identify structural heart disease abnormalities: a spatial and machine learning analysis.

INTRODUCTION: This study aims to obtain data on the prevalence and incidence of structural heart disease in a population setting and, to analyse and present those data on the application of spatial and machine learning methods that, although known to geography and statistics, need to become used for healthcare research and for political commitment to obtain resources and support effective public health programme implementation. METHODS AND ANALYSIS: We will perform a cross-sectional survey of randomly selected residents of Salamanca (Spain). 2400 individuals stratified by age and sex and by place of residence (rural and urban) will be studied. The variables to analyse will be obtained from the clinical history, different surveys including social status, Mediterranean diet, functional capacity, ECG, echocardiogram, VASERA and biochemical as well as genetic analysis. ETHICS AND DISSEMINATION: The study has been approved by the ethical committee of the healthcare community. All study participants will sign an informed consent for participation in the study. The results of this study will allow the understanding of the relationship between the different influencing factors and their relative importance weights in the development of structural heart disease. For the first time, a detailed cardiovascular map showing the spatial distribution and a predictive machine learning system of different structural heart diseases and associated risk factors will be created and will be used as a regional policy to establish effective public health programmes to fight heart disease. At least 10 publications in the first-quartile scientific journals are planned. TRIAL REGISTRATION NUMBER: NCT03429452.

Falls prevention strategies for patients over 65 years in a neurology ward: a best practice implementation project.

OBJECTIVES: The aim of this project was to promote evidence-based practice with regard to fall prevention and management, by implementing the recommendations from the best available evidence to reduce fall rates. INTRODUCTION: Falls are a main cause of disability in older people and the most common adverse event in all hospital patients. It is essential to implement the recommendations from evidence-based interventions to reduce these events. METHODS: A pre and post implementation audit method was used in a neurology ward, which employed the Joanna Briggs Institute Practical Application of Clinical Evidence System (JBI PACES) and Getting Research Into Practice (GRiP) module. The 15-month project evaluated between 20-30 patients from a sample at each audit (baseline in April 2016 and during three follow-up cycles in December 2016, March 2017 and June 2017). The data were inputted into an informatics system from nursing records and audited according to evidence-based processes and outcomes criteria. RESULTS: The baseline outcomes identified five barriers: incomplete fall registration, lack of an established fall prevention protocol for at-risk patients, limited knowledge about the fall prevention protocol, lack of a fall risk assessment scale and lack of multifactorial individual plans for fall prevention. Strategies were carried out and implemented following GRiP and all the criteria improved from baseline. CONCLUSIONS: The project successfully increased evidence-based practice on falls and provided mechanisms for sustaining evidence-based practice changes. Further audits are needed to improve some outcomes.

Efficacy of the Otago Exercise Programme to reduce falls in community-dwelling adults aged 65-80 years old when delivered as group or individual training.

AIM: This study will compare how falls can be reduced in non-institutionalized older Spanish adults aged 65-80 years by providing group or individual exercise sessions using the Otago Exercise Programme. BACKGROUND: The Otago Exercise Programme is a progressive home-based exercise programme, where trained health professionals help people engage in strength, balance and endurance exercises. Its format is based on the evidence from four clinical trials. The benefits of the Otago Exercise Programme are the same for people who have and have not suffered falls and it can also be used for visually impaired people. DESIGN: A multicentre, simply blinded, randomized, non-inferiority clinical trial, with two arms-group training and individual training-that started in January 2017 and will continue until December 2019. METHODS: Each study group has 364 subjects, who will take part in four individual or group sessions delivered mainly by nurses over an 8-week period, with a reinforcement session 6 months later. Data will be collected at baseline and after 6 and 12 months. The fall percentage will be the most relevant clinical variable and we will also consider safety, viability, compliance, economic analysis and therapeutic value. Approval and funding was granted in December 2016 for this 3-year study by the Spanish Health Research Fund (PI16CIII/00031). DISCUSSION: Older people from 65-80 years old tend to be more isolated and tackling worries about falls can improve social activities and independence. It has been shown that group training provides better adherence to exercise than individual training and this study will test that hypothesis for the Otago Exercise Programme.
