Article Synopsis
  • A novel deep learning (DL) system was developed to enhance the interpretation of transthoracic echocardiography (TTE) for assessing the severity of mitral regurgitation (MR) by integrating multiple video assessments.
  • The system was tested with a large dataset (over 61,000 TTEs) and showed high accuracy in classifying MR severity, achieving exact accuracy rates of 82% for internal and 79% for external test sets.
  • Most misclassifications occurred between none/trace and mild MR categories, and the use of multiple TTE views improved classification accuracy.

Article Synopsis
  • Previous research on professional basketball athletes has mostly focused on male athletes and female echocardiography, resulting in a lack of ECG data specific to female athletes.
  • The study aimed to create reference ECG data for female professional basketball players, collecting data during mandatory preseason screenings between April and May 2022 and analyzing it from February to July 2023.
  • Of the 173 women analyzed, 78.6% showed training-related ECG changes, while 4.6% had abnormal findings, with a significant number also displaying left ventricular adaptations linked to athletic remodeling.

Introduction: Children have a high consumption of antimicrobials that require complicated decision-making by prescribers. Despite this, antimicrobial stewardship (AMS) interventions are often not translated into paediatric medicine. Script is a smartphone application (app) launched in Auckland, New Zealand to support decision-making for antimicrobial prescribers.

Background: Mobile health platforms like smartphone apps that provide clinical guidelines are ubiquitous, yet their long-term impact on guideline adherence remains unclear. In 2016, an antibiotic guidelines app, called SCRIPT, was introduced in Auckland City Hospital, New Zealand, to provide local antibiotic guidelines to clinicians on their smartphones.

Objective: We aimed to assess whether the provision of antibiotic guidelines in a smartphone app resulted in sustained changes in antibiotic guideline adherence by prescribers.

Children are entitled to receive antibiotic therapy that is based on evidence and best practice, but might be overlooked in hospital programmes designed to achieve antimicrobial stewardship [AMS]. This failure to include children could be because children make up small proportion of patients in most hospitals, and are cared for by specialised paediatric staff. We reviewed the evidence and consulted experts in three global regions to develop ten recommendations for good-practice in hospital AMS programmes for children.

Climate change is a worsening global crisis that will continue negatively impacting population health and well-being unless adaptation and mitigation interventions are rapidly implemented. Climate change-related cardiovascular disease is mediated by air pollution, increased ambient temperatures, vector-borne disease and mental health disorders. Climate change-related cardiovascular disease can be modulated by climate change adaptation; however, this process could result in significant health inequity because persons and populations of lower socioeconomic status have fewer adaptation options.

The coronavirus disease 2019 (COVID-19) pandemic has been the defining healthcare issue since its outbreak, consuming healthcare systems and disrupting all aspects of human life throughout 2020 and continuing through 2021. When reviewing cardiovascular disease (CVD) prevention throughout the COVID-19 pandemic, the first tendency may be to focus on the negative disruption. Months of quarantine, isolation, and missed healthcare visits or delayed care may have exacerbated the epidemic of CVD in the United States.

infective endocarditis is commonly treated with intravenous ampicillin/ceftriaxone combination therapy. Ampicillin, however, is unsuitable for outpatient parenteral antibiotic therapy (OPAT) regimens due to its instability in 24 h continuous infusors, and has been successfully replaced by benzylpenicillin used together with ceftriaxone in a few small case series. Since in vitro synergy data of penicillin/ceftriaxone against are still lacking, checkerboard assays were performed for 28 clinical isolates and one laboratory standard strain.

Preventive cardiology visits have traditionally focused on educating patients about disease risk factors and the need to avoid and manage them through lifestyle changes and medications. However, long-term patient adherence to the recommended interventions remains a key unmet need. In this review we discuss the rationale and potential benefits of a paradigm shift in the clinician-patient encounter, from focusing on education to explicitly discussing key drivers of individual motivation.

Adult working-class Americans spend on average 50% of their workday awake time at their jobs. The vast majority of these jobs involve mostly physically inactive tasks and frequent exposure to unhealthy food options. Traditionally, the workplace has been a challenging environment for cardiovascular prevention, where cardiovascular guidelines have had limited implementation.

Background: Treatment regimens requiring multiple daily dosing for enterococcal endocarditis are challenging to deliver in the outpatient setting. Continuous-infusion benzylpenicillin via a 24 h elastomeric infusor, combined with either once-daily gentamicin or ceftriaxone, requires only one nursing encounter daily and is commonly used in New Zealand.

Objectives: To assess the therapeutic success and adverse antibiotic effects of these regimens.
