Ethical implications of developing RNA-based therapies for cardiovascular disorders.

The awareness concerning RNA-based therapies was boosted significantly after the successful development of COVID-19 vaccines. However, they can potentially lead to significant advances in other areas of medicine, such as oncology or chronic diseases. In recent years, there has been an exponential increase in the number of RNA-based therapies that were evaluated as potential treatments for cardiovascular disorders. One of the areas that was not explicitly assessed about these therapies is represented by their overall ethical framework. Some studies evaluate ethical issues of RNA-based treatments in general or targeting specific disorders (especially neurodegenerative) or interventions for developing RNA-based vaccines. Much less information is available regarding the ethical issues associated with developing these therapeutic strategies for cardiovascular disorders, which is the main aim of this study. We will focus our analysis on three main topics: risk-benefit analysis (including the management of public awareness about these technologies), and justice (in both research and clinical medicine).

Physician-Patient Relationship in Current Cosmetic Surgery Demands More than Mere Respect for Patient Autonomy-Is It Time for the Anti-Paternalistic Model?

The ethical framework of cosmetic surgery is distinct from the one associated with clinical medicine. This distinctiveness has led to significant difficulties in conceptualizing the physician-patient relationship (PPR), as most models have been developed specifically for the latter. The purpose of this article is to show that the PPR in cosmetic surgery can be better described through a distinct approach that we name the anti-paternalistic model of the PPR, and we will briefly present the differences between it and autonomy-based models. We will analyze the principle of non-interference, the variable degree of autonomy of both the patient and the physician within this relationship, the handling of the relevant information, the principle of beneficence as satisfaction, the difficulties regarding the informed consent, the algorithm allowing for the refusal of the procedure, and children-related issues. Based on this analysis, we will show that an anti-paternalistic model of the PPR is preferable to an autonomy-based one, as it allows for better clarification of the underlying ethical issues involved in cosmetic surgery.

Duplication and transposition of inferior vena cava: A meta-analysis of prevalence.

OBJECTIVE: The primary aim of this article was to establish the actual prevalence of transposition and duplication of the inferior vena cava and to increase awareness about them. METHODS: A meta-analysis of prevalence was conducted of cases obtained from PubMed, Web of Science, and Scopus databases. RESULTS: A total of 48 studies contained data that allowed us to estimate the prevalence of these variants (39 for duplication and 32 for transposition). The overall prevalence of duplication was 0.7%, with a 95% confidence interval between 0.5% and 0.9%; for transposition, the prevalence was 0.3%, with a 95% confidence interval between 0.2% and 0.5%. The publication bias was minimal. Duplication prevalence was significantly higher in anatomy studies compared with imaging and surgery studies; for transposition, there were no statistically significant differences by detection technique. CONCLUSIONS: The overall prevalence of duplication of the inferior vena cava is 0.7%; for transposition, it is 0.3%. Even if they are obviously rare conditions, their presence must be suspected by practitioners as they can have important clinical consequences, may require changes in the surgery protocol, or can be associated with other congenital abnormalities.

New technologies in biomedicine. Opinions of young Romanian physicians / Nuevas tecnologías en biomedicina. Opiniones de médicos jóvenes de Rumania / Novas tecnologias em biomedicina. Opiniões de jovens médicos romenos

Aim. The purpose of this article is to summarize the way young medical professionals view these modern biomedical procedures and their moral acceptability. Materials and methods. A survey, filled in online, analyzing items in four main areas: genetic techniques, cloning, stem cell research, and assisted reproduction. Results. Genetics related items. Most subjects agreed that the right to the genetic material should be a fundamental human right and that genetic engineering should be used if it could lead to the elimination os severe genetic diseases like cystic fibrosis and thalassemia. The least acceptance rate was obtained for techniques that would either change physical traits (like eye or hair color) or augment them. Assisted reproductive techniques. Most subjects agreed that the prenatal screening should be mandatory, and if the screening detects a severe congenital malformation the physician should recommend therapeutic abortion. Cloning. Most subjects disagreed that cloning of any type, either therapeutic or reproductive, using human, animal, or vegetal genetic material. Stem cell research. Most subjects agreed with the collection and storage of cord blood stem cells and the use of adult stem cells, and most of them disagreed with the creation of embryos specifically for obtaining stem cells. Conclusions. Even if the national legislation in this area is very scarce, the responses have usually identified the highly controversial techniques. If however the national legislation has elements similar to the items from the survey, they tended to take the respective items as morally acceptable without trying to analyze them critically.

Objetivo. El propósito de este artículo es recoger la forma en que jóvenes profesionales médicos ven los procedimientos biomédicos modernos y su aceptabilidad moral. Materiales y métodos: Una encuesta, rellenada online, que analiza elementos en cuatro áreas principales: técnicas genéticas, clonación, investigación con células madre y reproducción asistida. Resultados: Elementos relacionados con la genética: La mayoría de los sujetos acepta que el derecho a material genético debería ser un derecho humano fundamental y que la ingeniería genética debería usarse si pudiese eliminar enfermedades genéticas severas como la fibrosis quística y la talasemia. Se obtuvo una frecuencia de aceptación menor para técnicas que pudieran o cambiar características físicas (como el color de los ojos o del pelo) o aumentarlas. Técnicas de reproducción asistida: La mayoría de los sujetos acepta que el examen de detección prenatal debiera ser mandatorio y si se detecta una deformación congénita severa, el médico debería recomendar aborto terapéutico. Clonación: La mayoría de los sujetos no acepta clonación de ningún tipo, terapéutica o reproductiva, usando material genético humano, animal o vegetal. Investigación con células madre: La mayoría de los sujetos acepta recoger y almacenar células madre del cordón umbilical y el uso de células madre adultas y está en desacuerdo con la creación de embriones específicamente para obtener células madre. Conclusiones: aunque la legislación nacional en esta área es muy escasa, las respuestas por lo general han identificado las técnicas altamente controversiales. Sin embargo, si la legislación nacional tiene elementos similares a los temas de la encuesta, se tiende a tomarlos respectivamente como moralmente aceptables sin tratar de analizarlos críticamente.

Objetivo. A proposta deste artigo é sumarizar o modo de ver dos jovens profissionais médicos sobre procedimentos biomédicos modernos e sua aceitação moral. Materiais e métodos. Uma pesquisa de opinião realizada online, analisou ítens de quatro principais áreas: técnicas genéticas, clonagem, pesquisa com células-tronco, e reprodução assistida. Resultados. Itens relacionados à Genética. A maioria dos sujeitos concordaram que o direito ao material genético deveria ser um direito humano fundamental e que a engenharia genética poderia ser usada se puder levar à eliminação de doenças genéticas severas como a fibrose cística e a talassemia. A menor taxa de aceitação foi obtida para técnicas que pudessem modificar o aspecto físico individual (como olho e cor do cabelo) ou aumentá-los. Técnicas de reprodução assistida. A maioria dos sujeitos concordaram que a seleção pré-natal (screening) deverá ser impositiva, e que se o "screening" detetar uma severa malformação congênita o médico deveria recomendar o aborto terapêutico. Clonagem. A maioria dos sujeitos discordaram da clonagem de qualquer tipo, terapêutica ou reprodutiva, com material genético de uso humano, animal, ou vegetal. Pesquisa com células-tronco. A maioria dos sujeitos concordaram com a obtenção e estocagem de células-tronco de sangue do cordão umbilical e a utilização de células-tronco adultas , e a maioria deles discordaram da criação de embriões especificamente para a obtenção de células-tronco. Conclusões. Mesmo que a legislação nacional na área seja muito escassa, as respostas usualmente identificaram as técnicas como altamente controversas. Quando a legislação nacional oferece elementos semelhantes aos ítens obtidos pela pesquisa de opinião, eles tenderiam a tomar os respectivos ítens como moralmente aceitáveis sem tentar analisá-los criticamente.

Lethal pulmonary thromboembolism associated with decreased thyroid hormone levels

Thyroid pathology is rarely involved in the pathogenesis of sudden death in young people. We report here the cases of two young patients with decreased levels of thyroid hormones whose death was caused by an increased thrombotic status, with venous thrombosis and pulmonary thromboembolism. In both cases the thyroid pathology was not considered as the underlying cause of death as the association between this condition and venous thrombosis is still debatable. However its presence may be considered a circumstantial factor, which could increase the severity of the disease and subsequently the lethality rate in pulmonary thromboembolism. An increased awareness for hypothyroidism or subclinical hypothyroidism in clinical practice may lead to a decrease in mortality secondary to thromboembolic disease. Also, increased awareness for thyroid pathology during forensic autopsy in sudden deaths may lead to potentially significant results, that could explain some of the sudden death with an unknown cause, and decrease the number of the so called blank autopsies.

Sudden death due to dissection of the thoracic aorta associated with dissection and rupture of the pulmonary artery: report of two cases.

We present two cases of dissection of the thoracic aorta associated with dissection and rupture of the pulmonary artery. In both cases the initial dissection was hypothesized to occur in the thoracic aorta, with secondary dissection and rupture of the pulmonary artery.

Complex Ebstein's malformation: defining preoperative cardiac anatomy and function.

INTRODUCTION: Ebstein's malformation is a congenital malformation of the tricuspid valve and right ventricle, with a highly variable morphology, and clinical presentation, accounting for less than 1% of all congenital heart diseases, and about 40% of congenital malformations of the tricuspid valve. METHOD: Systematic review of English language literature regarding the morphogenesis and progress of imaging techniques, especially echocardiography and cardiac magnetic resonance imaging, in the preoperative planning of Ebstein's malformation, using the MEDLINE database with the PubMed Entre interface. RESULTS: Technological developments of the recent years, with 3D echocardiographic and cardiac magnetic resonance imaging evolution, have resulted in better understanding of the malformed tricuspid valve and right ventricle in vivo anatomy. Through a better understanding of Ebstein's malformation, there is a continuous trend of surgical techniques favoring tricuspid valve sparing procedures, with a constant decrease in early and late postoperative mortality. CONCLUSIONS: Although imaging methods to investigate Ebstein's malformation have continuously evolved, standardization of assessment protocols by 3D echocardiographic imaging, speckle tracking imaging, and cardiac magnetic resonance imaging is required.
