Chikungunya and the Heart.

INTRODUCTION: Neglected tropical diseases are a group of communicable diseases that occur in tropical and subtropical conditions and are closely related to poverty and inadequate sanitation conditions. Among these entities, chikungunya remains one of the most widely spread diseases. Although the main symptoms are related to a febrile syndrome, cardiovascular (CV) involvement has been reported, with short- and long-term implications. As part of the "Neglected Tropical Diseases and other Infectious Diseases involving the Heart" (NET-Heart) Project, the aim of this review is to compile all the information available regarding CV involvement of this disease, to help healthcare providers gain knowledge in this field, and contribute to improving early diagnosis, treatment, and prevention strategies. METHODS: We adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement in conducting and reporting this systematic review. The search was conducted using MEDLINE/PubMed, SciELO, and LILACS databases to identify any relevant studies or reviews detailing an association between chikungunya and cardiac involvement published from January 1972 to May 31, 2020. RESULTS: Despite its mechanism not being fully understood, CV involvement has been described as the most frequent atypical presentation of chikungunya (54.2%). Myocarditis is the most prevalent CV complication. Different rhythm disturbances have been reported in 52% of cases, whereas heart failure was reported in 15% of cases, pericarditis in 5%, and acute myocardial infarction in 2%. Overall estimated CV mortality is 10%, although in patients with other comorbidities, it may increase up to 20%. In the proper clinical setting, the presence of fever, polyarthralgia, and new-onset arrhythmia suggests chikungunya virus-related myocarditis. CONCLUSION: Although most cases are rarely fatal, CV involvement in chikungunya infection remains the most frequent atypical presentation of this disease and may have severe manifestations. Timely diagnosis and appropriate management are necessary to improve patient outcomes.

Latin-American guidelines of recommendations at discharge from an acute coronary syndrome.

The diagnostic criteria, treatments at the time of admission, and drugs used in patients with acute coronary syndrome are well defined in countless guidelines. However, there is uncertainty about the measures to recommend during patient discharge planning. This document brings together the most recent evidence and the standardized and optimal treatment for patients at the time of discharge from hospitalization for an acute coronary syndrome, for comprehensive and safe care in the patient's transition between care from the acute event to the outpatient care, with the aim of optimizing the recovery of viable myocardium, guaranteeing the most appropriate secondary prevention, reducing the risk of a new coronary event and mortality, as well as the adequate reintegration of patients into daily life.

Los criterios diagnósticos, los tratamientos en el momento de la admisión y los fármacos utilizados en pacientes con síndrome coronario agudo están bien definidos en innumerables guías. Sin embargo, existe incertidumbre acerca de las medidas para recomendar durante la planificación del egreso de los pacientes. Este documento reúne las evidencias más recientes y el tratamiento estandarizado y óptimo para los pacientes al momento del egreso de una hospitalización por un síndrome coronario agudo, para un cuidado integral y seguro en la transición del paciente entre la atención del evento agudo y el cuidado ambulatorio, con el objetivo de optimizar la recuperación de miocardio viable, garantizar la prevención secundaria más adecuada, reducir el riesgo de un nuevo evento coronario y la mortalidad, así como la adecuada reinserción de los pacientes en la vida cotidiana.

Comparison of violence and aggressions suffered by health personnel during the COVID-19 pandemic in Argentina and the rest of Latin America. / Comparación de la violencia y agresiones sufridas por el personal de salud durante la pandemia de COVID-19 en Argentina y el resto de Latinoamérica.

OBJECTIVES.: Motivation for the study. The COVID-19 pandemic has caused profound repercussions at different socio-environmental levels. Its impact on violence against healthcare team workers in Argentina has not been well documented. Main findings. The present study evidenced high rates of aggression, particularly verbal aggression. In addition, almost half of the participants reported having suffered these events on a weekly basis. All participants who experienced violence reported having experienced post-event symptoms, and up to one-third reported having considered changing their profession after these acts. Implications. It is imperative to take action to prevent acts of violence against health personnel, or to mitigate its impact on the victims. . To explore the frequency and impact of violence against healthcare workers in Argentina and to compare it with the rest of their Latin American peers during the COVID-19 pandemic. MATERIALS AND METHODS.: A cross-sectional study was conducted by applying an electronic survey on Latin American medical and non-medical personnel who carried out health care tasks since March 2020. We used Poisson regression to estimate crude (PR) and adjusted (aPR) Prevalence Ratios with their respective 95% confidence intervals. RESULTS.: A total of 3544 participants from 19 countries answered the survey; 1992 (56.0%) resided in Argentina. Of these, 62.9% experienced at least one act of violence; 97.7% reported verbal violence and 11.8% physical violence. Of those who were assaulted, 41.5% experienced violence at least once a week. Health personnel from Argentina experienced violence more frequently than those from other countries (62.9% vs. 54.6%, p<0.001), and these events were more frequent and stressful (p<0.05). In addition, Argentinean health personnel reported having considered changing their healthcare tasks and/or desired to leave their profession more frequently (p<0.001). In the Poisson regression, we found that participants from Argentina had a higher prevalence of violence than health workers from the region (14.6%; p<0.001). CONCLUSIONS.: There was a high prevalence of violence against health personnel in Argentina during the COVID-19 pandemic. These events had a strong negative impact on those who suffered them. Our data suggest that violence against health personnel may have been more frequent in Argentina than in other regions of the continent.

OBJETIVOS.: Explorar la frecuencia e impacto de la violencia contra los trabajadores de salud de Argentina y compararlo con el resto de sus pares de Latinoamérica en el contexto de la pandemia por COVID-19. MATERIALES Y MÉTODOS.: Estudio de corte transversal a través de una encuesta electrónica al personal médico y no médico de Latinoamérica que desempeño tareas asistenciales desde marzo de 2020. Se utilizó una regresión de Poisson para estimar las Razones de Prevalencia crudas (RP) y ajustadas (RPa) con sus respectivos intervalos de confianza al 95%. RESULTADOS.: Un total de 3544 participantes de 19 países respondieron la encuesta; 1992 (56,0%) residían en Argentina. Entre los mismos, el 62,9% padeció al menos un hecho de violencia: 97,7% refirió violencia verbal y 11,8% violencia física. El 41,5% de los agredidos padecieron situaciones de violencia al menos una vez por semana. El personal de salud de Argentina vivenció más frecuentemente violencia que los de otros países (62,9% vs. 54,6%, p<0,001), siendo estos eventos más habituales y estresantes (p<0,05). Además, refirieron más frecuentemente haber considerado cambiar sus tareas asistenciales y/o deseos de abandonar su profesión (p<0,001). En la regresión de Poisson, los participantes de Argentina tuvieron una prevalencia de violencia mayor que los trabajadores de salud de la región (14,6%; p<0,001). CONCLUSIONES.: Existió una elevada prevalencia de violencia contra el personal de salud de Argentina durante la pandemia por COVID-19. Estos hechos tuvieron un alto impacto negativo entre quienes los padecieron. Nuestros datos sugieren que, esto podría haber sido más frecuente en Argentina respecto de otras regiones del continente.

Leishmaniasis and Heart.

As one of the neglected tropical diseases, leishmaniasis is defined as a parasitic communicable disease that is most prevalent in tropical and subtropical regions, affecting especially populations living in poverty. It has a profound negative impact on developing economies. It represents a group of heterogeneous syndromes with a wide spectrum of severity ranging from self-resolving cutaneous injuries to disseminated visceral compromise. Visceral leishmaniasis represents its most severe form, can affect almost all organs, and can have fatal consequences, especially in immunosuppressed patients. Cardiac involvement seems to be rare but has not been deeply studied. Consequently, there are no clear recommendations for the screening of cardiac manifestations in these patients. However, cardiovascular complications could be potentially lethal. In addition, there are valuable reports on the potential cardiotoxicity caused by drugs used in the treatment of this condition, so knowledge of its side effects could have important implications. This article is a part of the "Neglected Tropical Diseases and other Infectious Diseases affecting the Heart" project (the NET-Heart Project); its purpose is to review all the information available regarding cardiac implications of this disease and its treatment and to add knowledge to this field of study, focusing on the barriers for diagnosis and treatment, and how to adopt strategies to overcome them.

Como una de las enfermedades tropicales desatendidas (ETD), la leishmaniasis se define como una enfermedad parasitaria transmisible y muy prevalente en regiones tropicales-subtropicales afectando especialmente a poblaciones que viven en la pobreza. Tiene un profundo impacto negativo en las economías en vías de desarrollo. Representa un grupo heterogéneo de síndromes clínicos con un amplio espectro de severidad que va desde lesiones cutáneas que resuelven espontáneamente hasta compromiso visceral diseminado. La leishmaniasis visceral representa su forma más grave, puede afectar a casi todos los órganos del ser humano y suele tener consecuencias fatales, especialmente en pacientes inmunosuprimidos. La afectación cardíaca parece ser rara, pero nunca se ha estudiado en profundidad. En consecuencia, no existen recomendaciones claras para el cribado de las manifestaciones cardíacas en estos pacientes; sin embargo, las complicaciones cardiovasculares pueden ser potencialmente letales. Además, existen publicaciones sobre la potencial cardiotoxicidad provocada por los fármacos utilizados en el tratamiento de esta afección, por lo que el conocimiento de sus efectos secundarios podría tener importantes implicancias. Como parte del proyecto "Neglected Tropical Diseases and other Infectious Diseases affecting the Heart" (Proyecto NET-Heart), el propósito de este artículo es revisar toda la información disponible sobre el compromiso cardiovascular de esta enfermedad y su tratamiento y agregar conocimientos a este campo de estudio, centrándose en las barreras para el diagnóstico y tratamiento y cómo adoptar estrategias para superarlas.

Snakebite Envenomation and Heart: Systematic Review.

Snakebite envenomation is a neglected tropical disease which can result in morbidity and mortality. Cardiac implications are poorly understood due to the low frequency of cardiotoxicity combined with a lack of robust information, as snakebites commonly occur in remote and rural areas. This review aims to assess cardiovascular implications of snakebite envenoming and proposes an algorithm for screening of cardiovascular manifestations. A systematic review was performed and 29 articles relating to cardiovascular involvement in snakebite envenomation were selected. Cardiovascular involvement seems to be rare and includes a wide spectrum of outcomes, such as myocardial infarction, ventricular dysfunction, hypotension, cardiac arrest, and myocarditis. In a significant proportion of the cases analyzed (24.39%), the cardiovascular manifestations had major consequences (cardiac arrest, myocardial infarction, malignant ventricular arrhythmias, or death). Clinical monitoring, physical examination, and early electrocardiogram should be considered as key measures to detect cardiovascular involvement in patients with evidence of systemic illness.

Infarto agudo de miocardio en la República Argentina: Registro CONAREC XVII / Acute Myocardial Infarction in Argentina: CONAREC XVII Registry

Introducción El infarto agudo de miocardio (IAM) representa una de las principales causas de morbimortalidad en nuestro país. Tener datos sobre la realidad de esta entidad en la Argentina es de suma importancia como punto de partida para el desarrollo de políticas de prevención, así como para mejorar su tratamiento. Objetivo Describir variables demográficas, situaciones de estrés asociadas, tratamientos instaurados, tiempos en los que se implementaron, complicaciones intrahospitalarias y medicación al alta de pacientes ingresados con IAM en centros asociados al Consejo Argentino de Residentes de Cardiología (CONAREC). Material y métodos Entre diciembre de 2009 y julio de 2010 se incluyeron 1.182 pacientes consecutivos ingresados en 45 centros de todo el país con diagnóstico de IAM con o sin supradesnivel del segmento ST. Resultados La edad promedio fue de 64 ± 12 años; 705 pacientes presentaron IAM con supradesnivel del segmento ST (IAMCEST) y 477 IAM sin supradesnivel del segmento ST (IAMSEST). En el IAMCEST, la tasa de reperfusión fue del 92% de los pacientes elegibles, con la angioplastia como principal método (80%), con una demora prehospitalaria de 165 minutos y un tiempo puerta-balón de 80 minutos. En el IAMSEST se realizó coronariografía al 75% de los pacientes, con angioplastia al 46% de ellos. La principal complicación fue el desarrollo de insuficiencia cardíaca (22% en IAMCEST y 11% en IAMSEST), seguida por el sangrado y las arritmias. La mortalidad resultó del 8,8% en los IAMCEST y del 5,1% en los IAMSEST. Conclusiones Los pacientes con IAM que ingresan en centros con residencia médica presentan una tasa alta de reperfusión y tratamiento al egreso hospitalario, acorde a las recomendaciones internacionales. Encontramos aspectos para mejorar, como la elevada prevalencia de los factores de riesgo y los tiempos prehospitalarios prolongados, situaciones que no se han modificado en los últimos 15 años.

Introduction Acute myocardial infarction (AMI) is a major cause of morbidity and mortality in our country. It is very important to have data on the reality of this entity in Argentina as a starting point for the development of prevention policies and treatment improvement. Objective The aim of the study was to describe demographic variables, situations associated to stress, established treatments, implementation times, in-hospital complications and medication at discharge of patients with AMI admitted to centers associated to the Argentine Council of Residents in Cardiology (CONAREC). Methods Between December 2009 and July 2010, 1182 consecutive patients admitted to 45 centers across the country with a diagnosis of AMI with or without ST segment elevation were included in the study. Results Mean age was 64 ± 12 years; 705 patients presented AMI with ST segment elevation (STEMI) and 477 without ST segment elevation (NSTEMI). In the STEMI group, the reperfusion rate was 92% of eligible patients, with primary angioplasty in 80% of cases. In this group, prehospital time delay was 165 minutes and door-to-balloon time was 80 minutes. In the NSTEMI group), coronary angiography was performed in 75% of patients and 46% underwent angioplasty. The main complication was the development of heart failure (22% in the STEMI group and 11% in the NSTEMI group, followed by bleeding and arrhythmias. Mortality was 8.8% in the STEMI group and 5.1% in the NSTEMI group. Conclusions Patients with AMI admitted to centers with medical residency present with a high rate of reperfusion and treatment at hospital discharge, in agreement with international recommendations. We have found aspects to be improved such as the high prevalence of risk factors and prolonged prehospital time delays, situations which have not changed in the last 15 years.
