PURPOSE The structure of the mini-mental state examination (MMSE) is inconsistent across factor analytic studies, and yet to be examined based on network analysis. The current study aims to identify the (I) cross-sectional network structure and (II) longitudinal network changes of the MMSE. METHODS The MMSE was administered to a nationally representative sample of older adults (age 50 and over) in Ireland twice over 4 years (2012-2013 N = 7207; 2016 N = 5715). Psychometric network analysis was computed at each time point to identify structure, strength and magnitude of the network associations. Item clustering was examined, and modularity scores were computed to measure the overall strength of clustering. Centrality indices were used to identify the main aspects of the MMSE. Longitudinal differences between the networks were examined. RESULTS Cross-sectionally, the MMSE network structure clustered into a single community (modularity score = 0) with orientation items identified as most central. Longitudinally, the MMSE was time invariant regarding structure, centrality and magnitude of the positive associations between the items. The average magnitude of the negative associations increased over time[(t(65.15) = 3.78, p  less then  0.001; time 1 M = - 0.59, SD = 0.58 time 2 M = - 1.65, SD = 1.97] as did their percentage. CONCLUSION Network analysis of the MMSE showed that the measure consisted of a single entity of cognitive functioning irrespective of time. Orientation items were repeatedly identified as most central. Longitudinal changes of the network were evident in increased negative associations between selected cognitive components after 4 years of follow-up. These changes may be explained by neuro-cognitive compensation processes.In recent years, interventional cardiac magnetic resonance imaging (iCMR) has evolved from attractive theory to clinical routine at several centers. Real-time cardiac magnetic resonance imaging (CMR fluoroscopy) adds value by combining soft-tissue visualization, concurrent hemodynamic measurement, and freedom from radiation. Clinical iCMR applications are expanding because of advances in catheter devices and imaging. In the near future, iCMR promises novel procedures otherwise unsafe under standalone X-Ray guidance.Pediatric medical device approvals lag behind adult approvals. Historically, medical devices have rarely been designed specifically for children, but use in children has most often borrowed from adult or general use applications. While a variety of social, economic, and clinical factors have contributed to this phenomenon, the regulatory process remains a fundamental aspect of pediatric device development and commercialization. FDA's Center for Devices and Radiological Health (CDRH) has established programmatic and technological areas of advancement to support innovation that serves the public health needs of children and special populations. We highlight four regulatory areas that have the potential to shape the future of pediatric cardiology the CDRH Early Feasibility Study Program, advancements in 3D printing or additive manufacturing, computational modeling and simulation, and the use of real-world evidence for regulatory applications. These programs have the potential to impact all stages of device development, from early conception, design, and prototyping to clinical evidence generation, regulatory review, and finally commercialization. The success of these programs relies on a collaborative community of stakeholders, including government, regulators, device manufacturers, patients, payers, and the academic and professional community societies.There is no better representation of the need for personalization of care than the breadth and complexity of congenital heart disease. Advanced imaging modalities are now standard of care in the field, and the advancements being made to three-dimensional visualization technologies are growing as a means of pre-procedural preparation. Incorporating emerging modeling approaches, such as computational fluid dynamics, will push the limits of our ability to predict outcomes, and this information may be both obtained and utilized during a single procedure in the future. Artificial intelligence and customized devices may soon surface as realistic tools for the care of patients with congenital heart disease, as they are showing growing evidence of feasibility within other fields. This review illustrates the great strides that have been made and the persistent challenges that exist within the field of congenital interventional cardiology, a field which must continue to innovate and push the limits to achieve personalization of the interventions it provides.Small study sizes are a limiting factor in assessing outcome measures in pediatric cardiology. It is even more difficult to assess the outcomes of congenital catheterizations where the sample sizes are even smaller, particularly on a individual institutional level. The creation of multicenter registries is a method by which investigators can pool data to better assess quality and outcome measures of these procedures. No registry is perfect with several being available today, each with its own strengths and weaknesses. mTOR kinase assay In addition, there are a multitude of methods currently used to assess quality and outcomes from the data contained in these registries, each having its own limitations as well. Nonetheless, multicenter registrities remain one of the best available options to improve the quality of care for pediatric interventional cardiac catheterization. Below, we provide an overview of the current state of quality assessment/improvement in pediatric interventional cardiology including a review of the available registrities and the metrics used to measure quality of care and outcomes.Increasingly the importance of how and why we make decisions in the medical arena has been questioned. Traditionally the aeronautical and business worlds have shed a light on this complex area of human decision-making. In this review we reflect on what we already know about the complexity of decision-making in addition to directing particular focus on the challenges to decision-making in the high-intensity environment of the pediatric cardiac catheterization laboratory. We propose that the most critical factor in outcomes for children in the catheterization lab may not be technical failures but rather human factors and the lack of preparation and robust shared decision-making process between the catheterization team. Key technical factors involved in the decision-making process include understanding the anatomy, the indications and objective to be achieved, equipment availability, procedural flow, having a back-up plan and post-procedural care plan. Increased awareness, pre-catheterization planning, use of standardized clinical assessment and management plans and artificial intelligence may provide solutions to pitfalls in decision-making.
