Assessing the level of evidence of presented studies at the Brazilian Congress of Coloproctology

Introduction: Scientific studies in Brazil grew around 10.7% compared to previous years. However, the level of quality of evidence has been decreasing. The aim in our study is to examine the meeting abstracts of the Brazilian congress of coloproctology and analyze the level of evidence in trends and variables. Methods: A descriptive bibliometric study, working with secondary data to review scientific abstracts in the annals of the coloproctology congress from 2015 to 2019. Results: A total of 1756 abstracts of the Brazilian Congress of Coloproctology were analyzed for 5 years (2015-2019). There was a higher trend of abstracts presented with lower levels of evidence (level of evidence 5: 52.3% and 3: 30%), being the majority composed of case reports (49.4%) and retrospective studies (30.4%). The last two years analyzed (2018: 55.2% and 2019: 59.3%) had a predominance above average of case reports. From 2017 to 2019 there was a significant decrease in the number of level 2 evidence studies (18.10%,11.80% and 5.50%), while the number of studies with level 5 evidence showed an increase (45.60%, 56.60% and 61.40%). Statistical analysis occurred in only 17%, with an important decrease for the last two years (2018: 13.6%; 2019: 12.1%). Conclusions: Although the data of this study is from the Brazilian coloproctology point of view, they are important for the global scientific community, as they allow a quantitative evaluation of the relative contribution from the level of evidence of Brazilian coloproctology researchers to the scientific scenario.

Introduction: the COVID-19 pandemic brought about a change in our health and education system. Training programs also had to adapt and required rapid change. Objectives: to describe an educational experience of virtual/hybrid teaching in clinical research between teachers of the Clinical Service of a university hospital and medical students of a private institution who participated in the ESIN Program (Students in Research). Methodology: the contents and educational strategies included audio or videotaped lectures (asynchronous and self-administered), project-based learning, practical workshops (virtual and group synchronous meetings) by adopting learning models such as the inverted classroom, and individual tutoring between teacher and student. We gathered the data through observation in academic contexts and based on elements of anonymous satisfaction surveys, with prior informed consent of participants. Results: fourteen students participated, six in 2021 and eight in 2022. All were women and medical students (50% fourth year, 35% sixth year, and 15% fifth year). The techniques implemented favored participation and promoted active, project-based learning. They mentioned positive aspects such as the practical academic approach, the availability of the teaching team for any doubts, the time and enthusiasm for teaching, and encouraging participation. The theory videos were a valuable review tool, and team meetings received high praise even if the one-on-one meetings received much attention as help and support before the scientific congresses. In general, they stated that it was an enriching experience that showed that you can achieve what you thought impossible. All of them actively participated in at least one scientific congress, and 50% were co-authors of an academic publication. Conclusion: the students assumed commitments and responsibilities and incorporated competencies and skills in project implementation and dissemination. This educational experience helped to optimize class time for exchange, discussion, and doubts. The resources produced, the activities developed, and the contents addressed are now available at the institutional level. (AU)

An American and Brazilian perspective on abstracts presented in coloproctology conferences converted into published manuscripts

Introduction: The presentation of abstracts in a congress is an important step for the dissemination of scientific information. The American Congress of Coloproctology is promoted by the American Society of Colon & Rectal Surgeons (ASCRS), and it is the largest in number of participants within the specialty, followed by the Brazilian Congress of Coloproctology. The present study aims to evaluate variables related to the quality of the scientific production of the abstracts presented in these two events and their conversion rate to published manuscripts. Materials and Methods: The present bibliometric study assesses secondary data from the review of abstracts presented in these 2 important conferences in 2016, followed by a research of the publications from these congress presentations. Results: The total number of abstracts evaluated was 854. The rate of articles containing statistical analyses was of 73.7% in the American congress, and of 34.1% in the Brazilian congress. Multicentric studies were more prevalent in the American congress (23.1%). Regarding study design, the most common were case reports in the Brazilian (44.8%) congress and retrospective studies in the American congress (67.7%). As for the works presented, the rate of conversion into full manuscripts in the American congress was of 24.2% compared with 10.6% in the Brazilian congress. Most papers from the American congress (93.7%) have citations compared with 68.6% of the other event evaluated. Conclusion: The scientific performance demonstrated by the conversion rate of abstracts into publications is below ideal, mainly in relation to the Brazilian meeting; yet, there were significant differences between the two events in terms of the profile of the presentations and several variables analyzed.

Confiabilidad de una escala de valoración de resúmenes para congresos

Introducción: En 2013, desarrollamos una escala, para evaluar resúmenes de congresos de la Sociedad de Cirujanos de Chile (SOCICH). Objetivo: Determinar consistencia interna y confiabilidad interobservador de una escala para evaluar resúmenes de congresos. Material y Método: Estudio de confiabilidad. Doce cirujanos fueron capacitados de forma virtual durante 8 horas, para aplicar la escala. Una vez finalizado el entrenamiento, se les envió un cuestionario para evaluar contenidos de la capacitación, y varios resúmenescasos para ser evaluados con la escala antes señalada. Se aplicó estadística descriptiva, luego se estimó el grado de acuerdo entre observadores para cada ítem de la escala. Posteriormente, se evaluó el coeficiente de correlación (CCI), utilizando un modelo de dos factores mixtos en el que los efectos de los evaluadores son aleatorios y los ítems fijos; utilizando una definición de acuerdo absoluto. Además, se evaluó la consistencia interna de los ítems utilizando alfa de Cronbach, considerando intérvalos de confianza del 95% (IC 95%). Resultados: Luego de analizar las mediciones de los 9 ítems por los 12 observadores, se verificó que el CCI fue de 0,871; con un IC 95% de 0,700; 0,965. El valor de la consistencia interna fue de 0,7 considerando los 9 ítems, no se recomienda eliminar ningún ítem. Conclusión: La escala tiene buena confiabilidad interobservador y los ítems son consistentes entre sí; por lo que puede ser considerada como un instrumento confiable para la valoración de resúmenes de congresos.

Background: In 2013, we developed a scale to evaluate the abstracts of the congresses of the Society of Surgeons of Chile (SOCICH). Objective: To determine internal consistency and interobserver reliability of a scale to evaluate conference abstracts. Material and Methods: Reliability study. Twelve surgeons were trained virtually for 8 hours, to apply the scale. Once the training was finished, they were sent a questionnaire to evaluate the contents of the training, and several summaries-cases to be evaluated with the aforementioned scale. Descriptive statistics were applied, then the degree of agreement between observers was estimated for each item of the scale. Subsequently, intraclass correlation coefficient (ICC) was evaluated, using a mixed two-factor model where the effects of the evaluators are random and the items are fixed, using a definition of absolute agreement. In addition, the internal consistency of the items was evaluated using Cronbach's alpha, considering 95% confidence intervals (95% CI). Results: After analyzing the measurements of the 9 items by the 12 observers, it was verified that the ICC was 0.871; with a 95% CI of 0.700; 0.965. The internal consistency value was 0.7 considering the 9 items, it is not recommended to delete any item. Conclusions: The scale has good internal consistency and interobserver reliability. Therefore, it can be considered as reliable instrument to be used in the evaluation of abstracts for congresses.

Presencia de las distintas áreas quirúrgicas en el Congreso Nacional de Cirugía. Análisis de los últimos 12 años

Introducción: Los trabajos científicos permiten divulgar, compartir y contrastar resultados a terceros. Una de las formas de ver la actividad investigativa de cada especialidad es a través de las presentaciones que realizan en reuniones científicas. Objetivo: Describir el número de presentaciones de las distintas especialidades o áreas quirúrgicas en Chile en el principal congreso realizado a nivel nacional y evaluar si el comportamiento fue distinto durante los años de pandemia por coronavirus. Material y Método: Estudio bibliométrico del Congreso Chileno de Cirugía entre los años 2010 y 2021 evaluando el número total de presentaciones por área quirúrgica, año de presentación y período categorizado en 2010 a 2019 y 2020 a 2021. Se realiza estadística descriptiva y análisis de asociación de medias de publicaciones por área y período. Resultados: Se identificaron 4.462 presentaciones, incluyendo resúmenes orales, póster, videos y jornada de residentes. La media total fue 371,8 trabajos anuales. Coloproctología y Cirugía Gastroesofágica aportaron un total de 616 (13,8%) y 598 (13,4%) respectivamente. La media de presentaciones anuales previo a la pandemia por coronavirus fue de 414, en contraste a los 160 trabajos anuales durante ella, existiendo una disminución significativa de medias de presentaciones por área de 27,6 (± 18,8) a 10,7 (± 8,69) (p < 0,001), sin diferencias sus porcentajes de participación respecto del total (p = 0,776). Conclusión: Coloproctología y Cirugía Gastroesofágica son las áreas quirúrgicas más representadas. Si bien en el período contemporáneo a la pandemia por coronavirus significó una disminución en las presentaciones, no se observó una modificación en el porcentaje de participación de algún área en particular.

Introduction: Scientific studies allow the disclosure, sharing and comparison of results with third parties. One of the ways to see the investigative activity of each medical specialty is through the presentations they make at scientific meetings. Aim: To describe the number of presentations of the different surgical specialties or areas in Chile in the main congress held at a national level and to assess whether the behavior was different during the years of the coronavirus pandemic. Material and Method: Bibliometric study of the Chilean Congress of Surgery between 2010 and 2021, evaluating the total number of presentations by surgical area, year of presentation and two categorized periods (2010 to 2019 and 2020 to 2021). Descriptive statistics and association analysis of publication means by area and period are performed. Results: 4,462 presentations were identified, including oral summaries, posters, videos, and residents' sessions, with a mean of 371.8 per year. Coloproctology and Gastroesophageal Surgery contributed a total of 616 (13.8%) and 598 (13.4%) respectively. The mean number of annual presentations prior to the coronavirus pandemic was 414, in contrast to the 160 annual works during it, with a significant decrease in the mean number of presentations per area from 27.6 (± 18.8) to 10.7 (± 8.69) (p < 0.001), without differences in their percentages of participation with respect to the total (p = 0.776). Conclusion: Coloproctology and Gastroesophageal Surgery are the most represented surgical areas. Although the contemporary period of the coronavirus pandemic meant a decrease in presentations, no change was observed in the percentage of participation in any particular area.

Crossing the Death Valley of publication process in cornea and ocular surface diseases: from abstracts presented at the Association for Research in Vision and Ophthalmology annual meeting to full-text manuscripts / Atravessando o Vale da Morte do processo de publicação sobre doenças da córnea e da superfície ocular: de resumos apresentados no Encontro Anual da Associação de Pesquisa em Visão e Oftalmologia até artigos completos

ABSTRACT Purpose: This study was conducted to analyze the profile and publication rate of abstracts in indexed journals presented in the cornea section at the Association for Research in Vision and Ophthalmology Annual Meeting and to further identify potential predictive factors for better outcomes. Methods: Abstracts accepted for presentation at the 2013 Association for Research in Vision and Ophthalmology Annual Meeting in the cornea section were sought via PubMed and Scopus to identify whether they had been published as full-text manuscripts. First author's name, time of publication, journal's name, and impact factor were recorded. A multivariate regression was performed to explore the association between variables and both the likelihood of publication and the journal's impact factor. A Kaplan-Meier analysis was performed to evaluate the time course of publication of abstracts. Results: Of the 939 analyzed abstracts, 360 (38.3%) were published in journals with a median impact factor of 3.4. The median time interval between abstract submission and article publication was 22 months. The multivariate analysis revealed that abstracts were more likely to be published if they were funded (OR=1.482, p=0.005), had a control group (OR=1.511, p=0.016), and had a basic science research scope (OR=1.388, p=0.020). The journal's impact factor was higher in funded studies (β=0.163, p=0.002) but lower in multicenter studies (β=-0.170, p=0.001). The Kaplan-Meier analyses revealed significant differences in the publication time distribution for basic science vs clinical abstracts (χ2=7.636), controlled vs uncontrolled studies (χ2=6.921), and funded vs unfunded research (χ2=13.892) (p<0.05). Conclusion: Almost 40% of Association for Research in Vision and Ophthalmology abstracts were published within 5 years from submission. Funding support, basic research scope, and controlled design were the determinants of better outcomes of publication.(AU)

RESUMO Objetivo: Analisar o perfil e a taxa de publicação em periódicos indexados de resumos apresentados na seção de córnea da reunião anual da Association for Research in Vision and Ophthalmology - ARVO, para identificar potenciais fatores preditivos com objetivo de obter melhores resultados. Métodos: Artigos que foram aceitos para apresentação no encontro anual da Association for Research in Vision and Ophthalmology - ARVO 2013 na seção de córnea foram pesquisados via PubMed e Scopus para identificar se haviam sido publicados como manuscritos com texto integral. Nome do primeiro autor, data de publicação, nome da revista e fator de impacto foram registrados. Foi feita uma regressão multivariada para estabelecer uma associação entre as variáveis e a chance de publicação e o fator de impacto da revista. Foi utilizado o método Kaplan-Meier para analisar o tempo da apresentação até a publicação dos artigos. Resultados: Dos 939 artigos analisados, 360 (38.3%) foram publicados em revistas com um fator de impacto médio de 3.4. O intervalo de tempo entre a submissão do resumo e a publicação do artigo teve como mediana 22 meses. Na análise multivariada, resumos tinham mais chance de publicação se tinham algum tipo de financiamento (OR=1.482, p=0.005), tinham grupo controle (OR=1.511, p=0.016) e estavam no âmbito da pesquisa científica básica (OR+1.388, p=0.020). O fator de impacto da revista era maior em estudos financiados (β=0.163, p=0.002) e mais baixo naqueles multicêntricos (β=-0.170, p=0.001). A análise Kaplan-Meier mostrou diferenças significativas na distribuição de tempo até a publicação de resumos de ciência básica vs clínicos (χ2=7.636), com grupo controle vs sem grupo controle (χ2=6.921) e financiados vs não financiados (χ2=13.892) (p<0.05). Conclusão: Aproximadamente 40% dos resumos apresentados no encontro da Association for Research in Vision and Ophthalmology - ARVO foram publicados dentro de 5 anos da submissão. Financiamento, pesquisa no âmbito da ciência básica e presença de grupo controle foram fatores determinantes para melhores resultados em relação à chance de publicação.(AU)

El programa científico de las reuniones anuales de la Sociedad Cubana de Endocrinología y los congresos cubanos de endocrinología / The Scientific Program of the Annual Meetings of the Cuban Society of Endocrinology and the Cuban Congresses on Endocrinology

RESUMEN Después de la creación en 1953 de la Sociedad Cubana de Endocrinología, la actividad científica más importante en esta primera etapa fue la realización de las reuniones anuales. Como continuación de esas reuniones, a partir de la década de los ochenta del siglo pasado se inició de forma regular la realización de los congresos cubanos de endocrinología. El objetivo de la investigación fue describir el programa científico de las reuniones anuales de la Sociedad Cubana de Endocrinología. Se utilizó el método empírico de revisión documental de las actas de la Sociedad Cubana de Endocrinología en su primera etapa de creación, así como los programas de las reuniones anuales de la sociedad y de los congresos cubanos de endocrinología. Se realizaron tres reuniones anuales la primera el 16 de octubre de 1955 en Matanzas, la segunda el 29 de octubre de 1956 en Pinar del Río y la tercera el 11 de abril de 1959 en el Club de Leones de Marianao en La Habana. Entre los temas más tratados estaban la diabetes mellitus (40,4 por ciento de los trabajos presentados), misceláneas (21,4 por ciento), salud reproductiva (16,6 por ciento) y afecciones del tiroides (9,5 por ciento). Los médicos de mayor participación fueron Julio F. Schutte, Tomas Duran Quevedo, Manuel M. Villaverde, A. Ruiz Leiro y Genaro Suárez. La Sociedad Cubana de Endocrinología en la segunda etapa de trabajo desarrolló nueve congresos. La Sociedad Cubana de Endocrinología desde su fundación promovió la realización de reuniones científicas denominadas reuniones anuales, donde los médicos dedicados a estos temas presentaban lo más novedoso de sus investigaciones. Como continuación de esas reuniones, pero en un escenario social y científico diferente, se inició la realización regular de los congresos cubanos de endocrinología(AU)

ABSTRACT After the creation, in 1953, of the Cuban Society of Endocrinology, the most important scientific activity in this first stage was the holding of annual meetings. As a continuation of these meetings, starting in the 1980s, the Cuban congresses on endocrinology began on a regular basis. The objetive of the investigation was to describe the scientific program of the Annual Meetings of the Cuban Society of Endocrinology. The empirical method of documentary review was used, to search through the minutes of the Cuban Society of Endocrinology in its first stage of creation, as well as the programs of the Annual Meetings of the Society and of the Cuban congresses on endocrinology. Three annual meetings were held: the first one, on October 16, 1955, in Matanzas; the second one, on October 29, 1956, in Pinar del Río; the third one, on April 11, 1959, at Club de Leones in Marianao Municipality, Havana. Among the most addressed topics were diabetes mellitus (40.4 percent of the papers presented), miscellaneous issues (21.4 percent), reproductive health (16.6 percent), and thyroid-related conditions (9.5 percent). The physicians with the highest participation were Julio F. Schutte, Tomas Duran Quevedo, Manuel M. Villaverde, A Ruiz Leiro, and Genaro Suarez. The Cuban Society of Endocrinology, in its second stage of work, developed nine Cuban congresses on endocrinology. Since its creation, the Cuban Society of Endocrinology promoted the holding of scientific meetings called Annual Meetings, in which doctors dedicated to these issues presented the most innovative topics from among their research. As a continuation of these meetings, but in a different social and scientific setting, the regular holding of the Cuban congresses on endocrinology began(AU)

Las prácticas de laboratorio en la enseñanza de las ciencias básicas biomédicas ¿antes o después de los seminarios? / Laboratory practices in the teaching of basic biomedical sciences. Before or after seminars?

RESUMEN En este artículo se plantea la necesidad de reflexionar acerca de la ubicación que las prácticas de laboratorio tienen en el programa de las asignaturas básicas biomédicas. Se ofrecen algunas valoraciones sobre las bondades de esta forma organizativa para que los estudiantes adquieran conocimientos procedimentales y desarrollen capacidades que les permitan mayor independencia cognoscitiva sobre todo en semestres más avanzados de la carrera. Se dejan abiertas nuevas interrogantes acerca de si este posicionamiento pudiera modificar o no, la postura del docente como investigador en el aula y en consecuencia ejercer influencias autónomas para el desarrollo de las comentadas capacidades en los estudiantes, en concordancia con las exigencias de los nuevos planes de estudio.

ABSTRACT This article raises the need to reflect on laboratory practice location in the program of basic biomedical subjects. Some elements are offered about the benefits of this organizational form so that students acquire procedural knowledge and develop capacities that allow more cognitive independence, especially in more advanced semesters of the academic program. New questions are made about whether this positioning could modify or not, the teacher´s position as a classroom researcher and consequently exercise autonomous influences for the development of the aforementioned abilities in the students, in accordance with the requirements of the new academic formation plans.

Cabe destacar, asimismo, la presentación de la Guía de Prevención Primaria de la Enfermedad Cardiovascular, donde resalta el casi total abandono del ácido acetilsalicílico en prevención primaria debido a la falta de beneficio neto. Realizaremos un breve resumen de algunos de los principales trabajos científicos presentados: - Antithrombotic Therapy after Acute Coronary Syndrome or PCI in Atrial Fibrillation - The AUGUSTUS Trial - Transcatheter Aortic-Valve Replacement with a Balloon-Expandable Valve in Low-Risk Patients - The PARTNER 3 trial - The Safety and Efficacy of Femoral Access in STEMI: The SAFARI-STEMI Trial - One-Month Dual Antiplatelet Therapy Followed by Clopidogrel Monotherapy versus Standard 12-Month Dual Antiplatelet Therapy With Clopidogrel After Drug-Eluting Stent Implantation. STOP-DAPT 2 Trial - Results of a Large-scale, App-based Study to Identify Atrial Fibrillation Using a Smartwatch: The Apple Heart Study

Summary: As every year, on this occasion the 68th Congress of the American College of Cardiology was held from March 16 to 18 in New Orleans, Louisiana. Set in the city of Mardi Gras and jazz, it once again called on global cardiology to promote knowledge through the presentation of multiple scientific activities. It counted with the presence of more than 16.000 attendees and 2.300 articles were received, many of which will undoubtedly modify the current clinical practice. It is also worth mentioning the presentation of the Primary Prevention of Cardiovascular Disease Guideline, which highlights the almost total discontinuation of acetylsalicylic acid in primary prevention due to the lack of net benefit. We will make a brief summary of some of the main scientific papers presented: - Antithrombotic Therapy after Acute Coronary Syndrome or PCI in Atrial Fibrillation - The AUGUSTUS Trial - Transcatheter Aortic-Valve Replacement with a Balloon-Expandable Valve in Low-Risk Patients - The PARTNER 3 trial - The Safety and Efficacy of Femoral Access in STEMI: The SAFARI-STEMI Trial - One-Month Dual Antiplatelet Therapy Followed by Clopidogrel Monotherapy versus Standard 12-Month Dual Antiplatelet Therapy With Clopidogrel After Drug-Eluting Stent Implantation. STOP-DAPT 2 Trial - Results of a Large-scale, App-based Study to Identify Atrial Fibrillation Using a Smartwatch: The Apple Heart Study

Resumo: Como todos os anos, nesta ocasião, o 68º Congresso do Colégio Americano de Cardiologia (ACC após sua sigla em inglês) foi realizado de 16 a 18 de março em Nova Orleans, Louisiana. Situado na cidade do Mardi Gras e jazz, mais uma vez convidou a cardiologia do mondo para promover o conhecimento através da apresentação de múltiplas atividades científicas. Contou com a presença de mais de 16.000 participantes e 2.300 artigos recebidos, muitos dos quais sem dúvida modificarão a prática clínica atual. Também vale ressaltar a apresentação da Diretriz para a Prevenção Primária de Doenças Cardiovasculares, que destaca o quase total abandono do ácido acetilsalicílico na prevenção primária devido à falta de benefício líquido. Faremos um breve resumo de alguns dos principais trabalhos científicos apresentados: - Antithrombotic Therapy after Acute Coronary Syndrome or PCI in Atrial Fibrillation - The AUGUSTUS Trial - Transcatheter Aortic-Valve Replacement with a Balloon-Expandable Valve in Low-Risk Patients - The PARTNER 3 trial - The Safety and Efficacy of Femoral Access in STEMI: The SAFARI-STEMI Trial - One-Month Dual Antiplatelet Therapy Followed by Clopidogrel Monotherapy versus Standard 12-Month Dual Antiplatelet Therapy With Clopidogrel After Drug-Eluting Stent Implantation.

Lo mejor del Congreso 2018 de la American Heart Association / The best of the 2018 American Heart Association Meeting / O melhor do Congresso 2018 da American Heart Association

Resumen: El Congreso de la American Heart Association 2018 tuvo lugar en la ciudad de Chicago, Illinois, del 10 al 12 de noviembre. Contó con múltiples novedades, se presentaron tres nuevas guías de recomendaciones (abordaje de las bradicardias y trastornos de conducción, actividad física, y tal vez la más esperada, la nueva guía de tratamiento de las dislipemias). Al revisar las recomendaciones de 2013, los expertos norteamericanos introdujeron varios cambios, el más importante de los cuales quizá sea disminuir la trascendencia que se le da al cálculo del riesgo a diez años para volver a enfocarse en la meta de las lipoproteínas de baja densidad (LDL), bajo la premisa de que cuanto más bajo, mejor. Realizaremos un breve resumen de algunos de los principales trabajos científicos presentados durante este evento que, sin duda, tendrán una influencia importante en el futuro próximo de la cardiología mundial. - Reduction of Cardiovascular Events With Icosapent Ethyl-Intervention Trial - REDUCE-IT. - Vitamin D Supplements and Prevention of Cancer and Cardiovascular Disease - VITAL. - Angiotensin Receptor-Neprilysin Inhibition in Patients Hospitalized With Acute Decompensated Heart Failure: Primary Results of the PIONEER - HF Randomized Controlled Trial. - Pre-hospital Resuscitation Intra-arrest Cooling Effectiveness Survival Study - the PRINCESS Trial.

Summary: The American Heart Association 2018 Congress was held in the city of Chicago, Illinois, from November 10 to 12. There were many news, three new recommendations guidelines were presented (approach to bradycardia and driving disorders, physical activity, and perhaps the most anticipated, the new treatment guide for dyslipidemia). In reviewing the 2013 recommendations, US experts introduced several changes, the most important of which may be to reduce the significance of the 10-year risk calculation to refocus on the LDL goal, under the premise of that the lower, the better. We will make a brief summary of some of the main scientific papers presented during this event that will undoubtedly have an important influence in the near future of global cardiology. - Reduction of Cardiovascular Events With Icosapent Ethyl-Intervention Trial - REDUCE-IT. - Vitamin D Supplements and Prevention of Cancer and Cardiovascular Disease - VITAL. - Angiotensin Receptor-Neprilysin Inhibition in Patients Hospitalized With Acute Decompensated Heart Failure: Primary Results of the PIONEER-HF Randomized Controlled Trial. - Pre-hospital Resuscitation Intra-arrest Cooling Effectiveness Survival Study - the PRINCESS Trial.
