Young at Heart: Pioneering Approaches to Model Nonischaemic Cardiomyopathy with Induced Pluripotent Stem Cells

A mere 9 years have passed since the revolutionary report describing the derivation of induced pluripotent stem cells from human fibroblasts and the first in-patient translational use of cells obtained from these stem cells has already been achieved. From the perspectives of clinicians and researchers alike, the promise of induced pluripotent stem cells is alluring if somewhat beguiling. It is now evident that this technology is nascent and many areas for refinement have been identified and need to be considered before induced pluripotent stem cells can be routinely used to stratify, treat and cure patients, and to faithfully model diseases for drug screening purposes. This review specifically addresses the pioneering approaches to improve induced pluripotent stem cell based models of nonischaemic cardiomyopathy

Surgical Treatment of Atrial Fibrillation

Atrial fibrillation represents the most common supraventricular arrhythmia above all in patients undergoing cardiac surgery and is associated to an augmented risk of thromboembolic stroke, heart failure, and cardiovascular mortality. That is the reason why cardiac surgeons began to address their attention to how to surgically treat fibrillating patients according to pathophysiological models describing mechanisms of arrhythmia induction and maintenance. A new branch of cardiac surgery was born, leading to a progressive development of adapted surgical ablation techniques, applicable both to lone or concomitant arrhythmia treatment. Historical evolution and current available surgical treatment options are described, beginning from the first pure surgical maze, going through all its modifications in source ablation energies and lesion sets and finishing with current mini-invasive hybrid treatment of lone atrial fibrillation. Indications, patients’ selection, technical options with respective advantages and disadvantages, surgical technique details, complications, and results are fully illustrated. Relationship between pathophysiologic arrhythmia mechanisms and the consequent ablation tailored procedure choice is highlighted, allowing a customized procedural offer to every single patient, resulting in a success rate ranging from 60 to 90%

Empowering Sustainable Healthcare: The Role of Health Literacy

The imperative of sustainability in healthcare is becoming more pressing due to global health crises, climate change, and the rising burden of chronic diseases. Sustainability in healthcare involves social, economic, and environmental dimensions, each important for equitable and robust healthcare delivery. Health literacy may play a central role in embracing all three dimensions, bridging the gap between complex health information and individuals’ capability to understand and use it effectively: In fact, as a factor influencing the link between adverse social and economic conditions and subsequent health issues, health literacy could represent a practical target for mitigating health disparities within various demographic groups, thereby enhancing social sustainability. Furthermore, when people possess a solid understanding of their health conditions and the necessary steps for health management, they can contribute to a reduction in generated healthcare costs. Finally, health literacy and environmental health literacy equips individuals and communities with the knowledge and skills to understand how environmental factors affect health and empowers them to take proactive measures to protect the environment, potentially reducing the environmental impact of healthcare services. Therefore, integrating health literacy into education curricula and healthcare professional training is crucial for promoting sustainability. Despite some known barriers to the advancement and improvement of health literacy, such as limited awareness of its importance, the collaboration between academia, healthcare institutions, and community organizations is a path to follow to overcome these challenges

Current and future options for adult biventricular assistance: a review of literature

In cardiogenic shock various short-term mechanical assistances may be employed, including an Extra Corporeal Membrane Oxygenator and other non-dischargeable devices. Once hemodynamic stabilization is achieved and the patient evolves towards a persisting biventricular dysfunction or an underlying long-standing end-stage disease is present, aside from Orthotopic Heart Transplantation, a limited number of long-term therapeutic options may be offered. So far, only the Syncardia Total Artificial Heart and the Berlin Heart EXCOR (which is not approved for adult use in the United States unlike in Europe) are available for extensive implantation. In addition to this, the strategy providing two continuous-flow Left Ventricular Assist Devices is still off-label despite its widespread use. Nevertheless, every solution ensures at best a 70% survival rate (reflecting both the severity of the condition and the limits of mechanical support) with patients suffering from heavy complications and a poor quality of life. The aim of the present paper is to summarize the features, implantation techniques, and results of current devices used for adult Biventricular Mechanical Circulatory Support, as well as a glance to future options

Late mitral leaflet tear after transcatheter edge-to-edge repair for acute ischaemic mitral regurgitation: a case report

Background Acute mitral regurgitation due to papillary muscle rupture is a severe complication of acute myocardial infarction. Transcatheter edge-to-edge repair is emerging as an effective alternative to surgical treatment, with encouraging outcomes. Leaflet adverse events are rare and are associated with relapse of significant mitral regurgitation. Case summary A 54-year-old man arrived at our hospital with a late presentation of ST-elevation myocardial infarction. During primary percutaneous coronary intervention of the circumflex coronary artery, a partial papillary muscle rupture occurred with acute severe mitral regurgitation and cardiogenic shock. Due to the severe haemodynamic instability, the patient underwent an emergent transcatheter edge-to-edge repair with MitraClip device during Impella support with mitral regurgitation resolution and haemodynamic stabilization. At 2-month followup, an interclip leaflet tear occurred with relapse of severe mitral regurgitation, requiring a mitral valve replacement surgery. Discussion Acute mitral regurgitation due to papillary muscle rupture is a serious complication of acute myocardial infarction. Management is based on haemodynamic stabilization and surgery. The transcatheter edge-to-edge repair is emerging as a therapeutic alternative in high-risk cases. Leaflet adverse events rarely occur during the transcatheter edge-to-edge repair procedure or before patient discharge. Our case is the first to report a late leaflet adverse event, occurring two months after the procedure and, interestingly, after an acute myocardial infarction conditioning an ischaemic mitral regurgitation. This event may be the result of the progressive adverse remodelling of left ventricular inferolateral akinetic wall, with consequent increase of tethering forces on the posterior leaflet, tensioned in the opposite direction by the clip

How to communicate with older adults about climate change: a systematic review

IntroductionAlthough older adults are particularly vulnerable to the effects of climate change, they seem to be overall less concerned about it, and less inclined to support climate policies. The study aims to identify the communication strategies that have been evaluated in promoting awareness and/or climate friendly behaviors in older adults.MethodsWe searched multiple electronic databases for studies that evaluated the effects of any interventions aimed at communicating climate change to older persons (over 65 years) and assessed the results as awareness and /or behavioral changes. We selected quantitative, qualitative and mixed methods studies, and we also included systematic reviews for cross-referencing. Risk of bias of included studies was evaluated using different tools according to the study design.ResultsFrom a total of 5,486 articles, only 3 studies were included. One mixed-method study engaged older adults to assess the community vulnerability to climate change and to develop adaptation recommendations based on their perspectives; one qualitative study conducted focus groups to identify the more effective language, values and themes based on participants’ responses to narratives; one quantitative study utilized a 360-degree audio-visual platform allowing users to engage with immersive visualizations of sea-level rise scenarios.DiscussionDespite the paucity of literature, this review demonstrates the potential for different strategies to increase the awareness of older persons about climate change. The involvement of older adults in the communication process, the identification of their priorities, and the integration of technology in their daily lives are promising approaches but more research, including both quantitative and qualitative studies is recommended on this topic.Systematic review registerationFor further details about the protocol, this systematic review has been registered on PROSPERO on July 1, 2023 (https://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023438256)

Knowledge of public health informatics among Italian medical residents: design and preliminary validation of a questionnaire

Background: public health requires strong information skills and competencies, as it is information-intensive and information-driven. Public health informatics has been defined as the “systematic application of information, computer science, and technology to public health practice, research, and learning”. New information and communication technologies offer unprecedented opportunities, such as linking smart-phones and mobiles devices to web based tools for data collection, enabling and enhancing participatory epidemiology. However, being an emerging discipline, despite its potential and importance, public health informatics is often neglected and overlooked, being rarely offered as course. The present study was designed as a pilot study, with the aim of designing and validating a questionnaire on the knowledge of public health informatics among medical residents in public health in Italy.  Methods and Results: thirty-two Italian residents in public health volunteered to take part into the study. Mean age of the sample was 31.44±2.23 years, most responders were males (68.8%), from northern Italy (53.1%), at the third year of residency (34.4%) and currently doing practical training at the clinical management staff/hospital directorate (34.4%). Other places of training were the Prevention Department (21.9%), the Institute of Hygiene (18.8%), the local health units and the territory (12.5%), the occupational health service (6.3%) and the Regional Health Agency (3.1%). Cronbach’s alpha coefficient yielded a value of 0.909, demonstrating excellent psychometric properties of the instrument.  Conclusion: in conclusion, the developed questionnaire seems to be an appropriate and useful tool to detect gaps concerning knowledge, education and practices of public health informatics among residents in public health.&nbsp

Non infective severe aortic paravalvular leakage 7 years after surgery: the role of suture technique

We report a case of redo aortic prosthesis replacement for a severe paravalvular leak (PVL) in a man operated with continuous suture technique 7 years earlier. The severe aortic regurgitation was due to the rupture of the suture. In spite of operations to replace malfunctioning heart valves are common procedures and performed all over the world from more than 50 years, there is still an open debate about the most suitable suture technique. In this case report, we'll discuss if the suture technique has a role in preventing or leading complications as severe PVL
