Automating radiological measurements of the hip in children with cerebral palsy.

Aims: The aims of this study were to develop an automatic system capable of calculating four radiological measurements used in the diagnosis and monitoring of cerebral palsy (CP)-related hip disease, and to demonstrate that these measurements are sufficiently accurate to be used in clinical practice.

Methods: We developed a machine-learning system to automatically measure Reimer's migration percentage (RMP), acetabular index (ACI), head shaft angle (HSA), and neck shaft angle (NSA). The system automatically locates points around the femoral head and acetabulum on pelvic radiographs, and uses these to calculate measurements.

Advancing translational research in digital cardiac rehabilitation: The preparation phase of the Multiphase Optimization Strategy.

While digital cardiac rehabilitation (CR) is an effective alternative to center-based CR, its components and mechanisms of change remain poorly understood. The Multiphase Optimization Strategy (MOST) provides a framework that allows the effects of individual components of complex interventions to be studied. There is limited guidance within MOST on how to develop a conceptual model.

Supporting GPs and people with hypertension to maximise medication use to control blood pressure: a pilot cluster RCT of the MIAMI intervention.

Background: Hypertension, or high blood pressure, is a key modifiable risk factor for heart disease and stroke. International guidelines have highlighted 'poor adherence to treatment' and 'physician inertia' as major barriers to effective blood pressure management. The Maximising Adherence, Minimising Inertia (MIAMI) intervention, a theory-based complex intervention, supports General Practitioners (GPs) and people with hypertension in maximising medication use to manage blood pressure.

Factors influencing implementation of digital cardiac rehabilitation: A qualitative analysis of health workers perspectives.

Background: Despite growing evidence for the effectiveness of digital cardiac rehabilitation (CR) uptake of this technology remains low. Understanding the factors that influence implementation of digital CR in clinical practice is a growing area of research. The aim of this nested qualitative study was to explore health worker perspectives on factors influencing implementation of a digital CR programme.

Mainstream Germline Genetic Testing with Expanded Eligibility for Early Breast Cancer Patients in a Large Integrated Health System.

Background: This study evaluated a new mainstream genetic testing pathway for hereditary cancer, with expanded eligibility for early-stage breast cancer patients.

Methods: The study compared multigene panel (62 genes) germline testing uptake and results for breast cancer patients at 4 pilot sites (n = 502 patients) and 10 non-pilot sites (n = 1792 patients) within Kaiser Permanente Northern California from December 2020, to June 2021. At the pilot sites, breast care coordinators (BCCs) offered and consented patients for testing, with eligibility expanded to include all patients age 65 years or younger.

Climate change and cardiovascular health: Recent updates and actions for healthcare.

Climate change is a public health crisis predominantly due to fossil fuel combustion, that challenges planetary and human health. Considerable evidence exists to demonstrate the impact climate change has on cardiovascular disease primarily through air pollution, and non-optimal temperature. Conversely, healthcare systems themselves contribute substantially to climate change.

Predictors of incident stroke among individuals without coronary artery calcification: A pooled cohort analysis from the Multi-Ethnic Study of Atherosclerosis, Jackson Heart Study, and Framingham Heart Study.

Introduction: The absence of coronary artery calcium (CAC = 0) is associated with low risk of stroke events; however, predictors of incident stroke among those with CAC = 0 are not known.

Methods: Individual participant-level data were pooled from three prospective cohorts (Multi-Ethnic Study of Atherosclerosis [MESA], Jackson Heart Study, and Framingham Heart Study). Multivariable-adjusted Cox proportional hazards models were used to study the association between cardiovascular risk factors and incident adjudicated stroke among individuals with CAC = 0 who were free of clinical atherosclerotic cardiovascular disease at baseline.

Semaglutide and blood pressure: an individual patient data meta-analysis.

Background And Aims: Randomized clinical trials (RCTs) assessing semaglutide reported reductions of systolic blood pressure (SBP) in trial populations with baseline blood pressure in the normotensive range. This study aimed to determine whether this SBP reduction is greater in hypertensive groups.

Methods: Individual patient data (IPD) from three RCTs examining the effect of semaglutide 2.

Variation in secondary prevention of coronary heart disease: the INTERASPIRE study.

Background And Aims: INTERASPIRE is an international study of coronary heart disease (CHD) patients, designed to measure if guideline standards for secondary prevention and cardiac rehabilitation are being achieved in a timely manner.

Methods: Between 2020 and 2023, adults hospitalized in the preceding 6-24 months with incident or recurrent CHD were sampled in 14 countries from all 6 World Health Organization regions and invited for a standardized interview and examination. Direct age and sex standardization was used for country-level prevalence estimation.

fusion proteins deregulate gene networks controlling mitochondrial translation in pediatric rhabdomyosarcoma.

Alveolar rhabdomyosarcoma (ARMS) patients harboring PAX3-FOXO1 and PAX7-FOXO1 fusion proteins exhibit a greater incidence of tumor relapse, metastasis, and poor survival outcome, thereby underscoring the urgent need to develop effective therapies to treat this subtype of childhood cancer. To uncover mechanisms that contribute to tumor initiation, we developed a novel muscle progenitor model and used epigenomic approaches to unravel genome re-wiring events mediated by PAX3/7 fusion proteins. Importantly, these regulatory mechanisms are conserved across established ARMS cell lines, primary tumors, and orthotopic-patient derived xenografts.

Persuasion with Precision: Using Natural Language Processing to Improve Instrument Fidelity for Risk Communication Experimental Treatments.

Instrument fidelity in message testing research hinges upon how precisely messages operationalize treatment conditions. However, numerous message-testing studies have unmitigated threats to validity and reliability because no established procedures exist to guide of message treatments. Their construction typically occurs in a black box, resulting in suspect inferential conclusions about treatment effects.

Estimating uncertainty when providing individual cardiovascular risk predictions: a Bayesian survival analysis.

Background: Cardiovascular disease (CVD) risk scores provide point estimates of individual risk without uncertainty quantification. The objective of the current study was to demonstrate the feasibility and clinical utility of calculating uncertainty surrounding individual CVD-risk predictions using Bayesian methods.

Study Design And Setting: Individuals with established atherosclerotic CVD were included from the Utrecht Cardiovascular Cohort-Secondary Manifestations of ARTerial disease (UCC-SMART).
