RESUMEN
BACKGROUND: The COVID-19 pandemic has highlighted a correlation between cardiac complications and elevated cardiac biomarkers, which are linked to poorer clinical outcomes. OBJECTIVE: This study aims to determine the clinical impact of cardiac biomarkers in COVID-19 patients in Latin America. SUBJECTS AND METHODS: The CARDIO COVID 19-20 Registry is a multicenter observational study across 44 hospitals in Latin America and the Caribbean. It included hospitalized COVID-19 patients (n = 476) who underwent troponin, natriuretic peptide, and D-dimer tests. Patients were grouped based on the number of positive biomarkers. RESULTS: Among the 476 patients tested, 139 had one positive biomarker (Group C), 190 had two (Group B), 118 had three (Group A), and 29 had none (Group D). A directly proportional relationship was observed between the number of positive biomarkers and the incidence of decompensated heart failure. Similarly, there was a proportional relationship between the number of positive biomarkers and increased mortality. In Group B, patients with elevated troponin and natriuretic peptide and those with elevated troponin and D-dimer had 1.4 and 1.5 times higher mortality, respectively, than those with elevated natriuretic peptide and D-dimer. CONCLUSIONS: In Latin American COVID-19 patients, a higher number of positive cardiac biomarkers is associated with increased cardiovascular complications and mortality. These findings suggest that cardiac biomarkers should be utilized to guide acute-phase treatment strategies.
RESUMEN
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.

Two peach rootstocks ('Guardian' and 'MP-29') and ten winter cover crops (rye, wheat, barley, triticale, oat, Austrian winter pea, crimson clover, balansa clover, hairy vetch, and daikon radish) were evaluated in a greenhouse environment to determine their suitability to host ring nematode, Mesocriconema xenoplax. Each crop was inoculated with 500 ring nematodes, and the experiments were terminated 60 days after inoculation. The reproduction factor (ratio of final and initial nematode population) ranged from 0 to 13.8, indicating the crops greatly varied in their host suitability to ring nematode. 'Guardian' has been known to tolerate ring nematode; however, results from the current study suggest the tolerance statement is anecdotal. Another peach rootstock, 'MP-29', was also a good host for ring nematode, suggesting an urgency to develop ring nematode-resistant peach rootstocks. Wheat supported the least to no nematode reproduction while pea supported the greatest reproduction. The rest of the cover crops were poor to good hosts to ring nematodes. Although planting cover crops in peach orchards is not common, employing non or poor host crops can help suppress nematodes in addition to having soil health benefits. Furthermore, peach breeding programs should focus on finding and introgressing ring nematode resistance in commercial rootstocks.
RESUMEN
Resumen Introducción: La Sierra Santa Teresa se encuentra a 20 km al sureste de Hermosillo en la región central del estado de Sonora, México. Los estratos sedimentarios corresponden principalmente a textura de piedra caliza, mudstone, wackestone y packstone del Paleozoico superior. La biota está representada por crinoideos de las morfoespecies Baryschyr anosus, Cyclocaudex insaturatus, Floricyclus angustimargo, Cyclocion distictus, Lamprosterigma erathense y Preptopremnum rugosum en asociación con algas, foraminíferos fusulínidos, esponjas coralinas (Chaetetes sp), corales solitarios (Lophophyllidium sp., Fomichevella sp.), briozoos fenestélidos (Archimedes stoyanowi) y braquiópodos (Antiquatonia sp.). Objetivo: El objetivo principal de este estudio es dar a conocer la composición biótica de la Sierra Santa Teresa y sus consideraciones paleoecológicas y paleogeográficas. Métodos: En este estudio se sintetiza la información sobre las principales taxas recolectadas en afloramientos del Carbonífero de la Sierra, Santa Teresa. Resultados: La distribución de la biota, y particularmente de las morfoespecies de crinoideos, permitió hacer correlaciones paleobiogeográficas con otras localidades del Misisípico-Pensilvánico de México y de distintas regiones de los Estados Unidos de América, principalmente en Texas, Colorado, Illinois y Oklahoma, que se encontraban ubicadas al suroeste del Cratón norteamericano. Conclusiones: Se considera que el paleoambiente inferido con base en los registros paleontológicos de la Sierra Santa Teresa se trataba de mares someros que permitieron el desarrollo de comunidades de crinoideos, así como otros invertebrados como esponjas coralinas, corales solitarios, briozoos fenestélidos y braquiópodos, con un rango estratigráfico del Misisípico Medio-Superior (Chesteriano) al Pensilvánico Medio (Desmoinesiano).
Abstract Introduction: The Sierra Santa Teresa is located 20 km southeast of Hermosillo in the central region of Sonora state, Mexico. The sedimentary strata mainly correspond to limestone, mudstone, wackestone and packstone texture, from the upper Paleozoic. The biota is represented by crinoids of the morphospecies Baryschyr anosus, Cyclocaudex insaturatus, Floricyclus angustimargo, Cyclocion distictus, Lamprosterigma erathense, Preptopremnum rugosum in association with algae, fusulinid foraminifera, coralline sponges (Chaetetes sp.), solitary corals (Lophophyllidium sp., Fomichevella sp.), fenestellid bryozoans (Archimedes stoyanowi), and brachiopods (Antiquatonia sp.). Objective: The principal aim of this study is to analyze the biotic composition in the Sierra Santa Teresa and its paleoecological and paleogeographical considerations. Methods: In this study we synthetize information about the principal taxa collected in outcrops of the Carboniferous of the Sierra, Santa Teresa. Results: The distribution of the biota, and particularly the crinoid morphospecies, allowed paleobiogeographical correlations to be made with other Mississippian-Pennsylvanian localities of Mexico and different regions of the United States of America in Texas, Colorado, Illinois and Oklahoma, which were located in the southwestern of the North American Craton. Conclusions: It is considered that the paleoenvironment inferred based on the paleontological records of the Sierra Santa Teresa were shallow seas that allowed the development of communities of crinoids, as well as other invertebrates such as coralline sponges, solitary corals, fenestellid bryozoans and brachiopods, with a range stratigraphic from the Middle-Upper Mississippian (Chesterian) to the Middle Pennsylvanian (Desmoinesian).

Introduction: Gastric outlet obstruction or pyloric syndrome can occur secondary to neoplastic involvement, and metastasis as an etiology is unusual. Breast neoplasms generally cause bone, liver, and lung metastases, rarely involving the gastrointestinal tract. Case presentation: A 69-year-old female patient with infiltrating lobular carcinoma of the right breast consulted for abdominal pain and postprandial emetic episodes with oral intolerance and dyspnea. Bilateral neoplastic breast involvement and dilation of the gastric chamber with thickening of the pylorus were recorded. She required antiemetic management and placement of a nasogastric tube. She was taken to an upper digestive tract endoscopy, which found an ulcerated lesion with an infiltrative appearance at the postpyloric level that circumferentially compromised the duodenal lumen. Then, a biopsy was taken, which was compatible with a breast carcinoma of a lobular type. This entity, called pyloric syndrome due to neoplasia, can be managed with gastrojejunostomy or an enteral prosthesis that improves the quality of life of patients with an ominous short-term prognosis. The patient in our case expressed advance directives not to receive invasive procedures, for which an uncovered metal prosthesis was placed for palliative purposes, achieving the re-establishment of the feeding route and resolution of dyspnea due to restriction. Conclusions: The metastatic involvement of neoplasms of the breast to the gastrointestinal tract is rare; however, it should be suspected in elderly patients with previously documented neoplasms.
Introducción: La obstrucción al tracto de salida gástrico o síndrome pilórico puede presentarse de manera secundaria a compromiso neoplásico, y es inusual el compromiso metastásico como etiología. Las neoplasias de la mama generalmente originan metástasis óseas, hepáticas y pulmonares, y es infrecuente el compromiso del tracto digestivo. Presentación del caso: Se trata de una paciente de 69 años con carcinoma lobulillar infiltrante de mama derecha que consultó por dolor abdominal y episodios eméticos posprandiales con intolerancia a la vía oral y disnea. Se registró un compromiso neoplásico mamario bilateral y dilatación de la cámara gástrica con engrosamiento del píloro. Se dio manejo antiemético y colocación de sonda nasogástrica. Fue llevada a una endoscopia de vías digestivas altas en la que se encontró una lesión ulcerada de aspecto infiltrativo a nivel pospilórico que comprometía de forma circunferencial la luz duodenal, y luego se tomó una biopsia a este nivel, que fue compatible con un carcinoma mamario de tipo lobulillar. Esta entidad, denominada síndrome pilórico por neoplasias, puede manejarse con gastroyeyunostomía o con prótesis enteral que mejore la calidad de vida en pacientes con pronóstico ominoso a corto plazo. La paciente de nuestro caso manifestó voluntades anticipadas para no recibir procedimientos invasivos, por lo cual se ofreció la colocación de una prótesis metálica descubierta con fines paliativos y se logró el restablecimiento de la vía de alimentación y resolución de la disnea por restricción. Conclusiones: El compromiso metastásico de neoplasias de la mama al tracto digestivo es poco frecuente; sin embargo, debe sospecharse en pacientes de edad avanzada y con neoplasias previamente documentadas.
RESUMEN
Background: Socioeconomic factors contribute to a more severe impact of COVID-19 in Latin American and Caribbean (LA&C) countries than in developed countries. Patients with a severe or critical illness can develop respiratory and cardiovascular complications. Objective: To describe a LA&C population with COVID-19 to provide information related to this disease, in-hospital cardiovascular complications, and in-hospital mortality. Methods: The CARDIO COVID-19-20 Registry is an observational, multicenter, prospective, and hospital-based registry of patients with confirmed COVID-19 infection that required in-hospital treatment in LA&C. Enrollment of patients started on May 01, 2020, and ended on June 30, 2021. Results: The CARDIO COVID-19-20 Registry included 3260 patients from 44 institutions of 14 LA&C countries. 63.2% patients were male and median age was 61.0 years old. Most common comorbidities were overweight/obesity (49.7%), hypertension (49.0%), and diabetes mellitus (26.7%). Most frequent cardiovascular complications during hospitalization or reported at discharge were cardiac arrhythmia (9.1%), decompensated heart failure (8.5%), and pulmonary embolism (3.9%). The number of patients admitted to the Intensive Care Unit (ICU) was 1745 (53.5%), and median length of their stay at the ICU was 10.0 days. Support required in ICU included invasive mechanical ventilation (34.2%), vasopressors (27.6%), inotropics (10.3%), and vasodilators (3.7%). Rehospitalization after 30-day post discharge was 7.3%. In-hospital mortality and 30-day post discharge were 25.5% and 2.6%, respectively. Conclusions: According to our findings, more than half of the LA&C population with COVID-19 assessed required management in ICU, with higher requirement of invasive mechanical ventilation and vasoactive support, resulting in a high in-hospital mortality and a considerable high 30-day post discharge rehospitalization and mortality.

BACKGROUND: Chagas disease (ChD) is the most important endemy in Latin America. Some patients, develop chronic Chagasic cardiopathy (CCC) years after the acute phase. It is unknown if patients infected by the oral route have higher risk of developing early CCC. METHODS AND FINDINGS: A prospective cohort study was conducted to assess morbidity and mortality during 10 years observation in 106 people simultaneously infected and treated in the largest known orally transmitted ChD outbreak in 2007. A preschooler died during the acute phase, but thereafter was no mortality associated to ChD. All acute phase findings improved in the first-year post-treatment. Each person was evaluated 8.7 times clinically, 6.4 by electrocardiogram (ECG)/Holter, and 1.7 by echocardiogram. Based on prevalence, the number of people who had any abnormalities (excluding repolarization abnormalities and atrial tachycardia which decreased) was higher than 2007, since they were found at least once between 2008-2017. However, when we evaluated incidence, except for clinical bradycardia and dizziness, it was observed that the number of new cases of all clinical and ECG findings decreased at the end of the follow-up. Between 2008-2017 there was not incidence of low voltage complex, 2nd degree AV block, long QT interval, left bundle branch block or left ventricular dysfunction that allowed the diagnosis of CCC. Total improvement prevailed over the persistence of all clinical and ECG/Holter findings, except for sinus bradycardia. Incomplete right bundle branch block, sinus bradycardia and/or T-wave inversion were diagnosed persistently in 9 children. The second treatment did not have significant influence on the incidence of clinical or ECG/Holter findings. CONCLUSIONS: At the end of the 10-year follow-up, there were not clinical or ECG/Holter criteria for classifying patients with CCC. The incidence of arrhythmias and repolarization abnormalities decreased. However, special attention should be paid on findings that not revert as sinus bradycardia, or those diagnosed persistently in all ECG as sinus bradycardia, incomplete right bundle branch block or T-wave inversion. Early diagnosis and treatment may have contributed to the rapid improvement of these patients. In ChD follow-up studies prevalence overestimates the real dimension of abnormalities, the incidence looks as a better indicator.

Few studies have examined the role adverse childhood experiences (ACEs) have on specific diet patterns. This study assessed the association between ACEs and daily fruit and vegetable intake (FVI). Data were derived from the 2019 Behavioral Risk Factor Surveillance System (BRFSS) which surveys 50 states and three U.S. territories. Participants who completed the ACEs module were included in the analyses (N = 106,967). Total ACEs included the summed responses from the domains of abuse, household challenges, and neglect. FVI was reported by number of times consumed per day. The two fruit items included fruit (fresh, frozen, and canned) and fruit juice. The four vegetable items included leafy greens, fried potatoes, non-fried potatoes, and other vegetables. All fruit and vegetable items were analyzed separately to see which specific items drove the relationship between total ACEs and total FVI, equaling a total of 8 regression models. Every model controlled for poor mental health days, sex, age, ethnicity, income, body mass index, and physical activity. Total ACEs were positively associated with daily intake of fried potatoes (ß = 0.008, p =.025), other potatoes (ß = 0.008, p =.049), and other vegetables (ß = 0.024, p <.001). Total ACEs were negatively associated with daily intake of fruit (ß = -0.016, p <.001). ACEs had non-significant relationships with leafy greens and fruit juice. Findings suggests that those with increased ACEs scores report increased consumption of fried potatoes, non-fried potatoes, and other vegetables, and less of fruit. Findings highlight the need for understanding food context and preparation when analyzing the relationship between ACEs and diet intake.
RESUMEN
Introduction: Tuberculosis is an infectious disease that can be prevented and cured, but it is still associated with high morbidity and mortality rates. Disseminated tuberculosis, although rare, can occur in individuals with underlying pathologies that affect the immune system. Currently, there are limited reports on disseminated tuberculosis in individuals with congenital disorders. Clinical case: We present a case of a patient with a history of ß thalassemia who was admitted to the emergency department with symptoms of abdominal pain and constitutional symptoms. The final diagnosis was disseminated tuberculosis. This case is of particular interest due to its atypical presentation, the initial suspicion of malignancy, and the extensive involvement of the disease despite the patient's absence of immunosuppression history. Conclusions: Disseminated tuberculosis in immunocompetent patients is a rare presentation associated with poor outcomes. The history of ß thalassemia may be a risk factor to consider based on the metabolic pathways involved in the pathophysiology of both diseases.
Introducción: la tuberculosis es una enfermedad infecciosa prevenible y curable asociada a una alta morbimortalidad, la presentación de tuberculosis diseminada es poco frecuente y está asociada a patologías que comprometen el sistema inmunitario. En la actualidad hay pocos informes sobre tuberculosis diseminada y trastornos congénitos subyacentes. Caso clínico: paciente con antecedente de talasemia ß que ingresó al servicio de urgencias por dolor abdominal y síntomas constitucionales con diagnóstico final de tuberculosis diseminada. Es un caso de especial interés debido a la presentación atípica, la sospecha diagnóstica inicial de malignidad y el amplio compromiso de la enfermedad a pesar de que el paciente no tenía antecedentes de inmunosupresión. Conclusiones: la tuberculosis diseminada en el paciente inmunocompetente es una presentación poco frecuente asociada a desenlaces adversos. El antecedente de talasemia ß podría ser un factor de riesgo para tener en cuenta con base en las vías metabólicas involucradas en la fisiopatología de ambas enfermedades.
RESUMEN
BACKGROUND: Testicular tumors (TT) are infrequent in pediatric patients, representing 1% of pediatric solid tumors; benign testicular tumors (BTT) are the most common. We present a multicenter study aiming to describe the incidence, histology and surgical technique of BTT, with special emphasis on which approach could present better outcomes. METHODS: The records of pediatric patients diagnosed with BTT between 2005 and 2020 from 8 centers in 5 different countries in Latin-America, were reviewed. RESULTS: Sixty two BTTs were identified. 73% tumors presented as a testicular mass, and 97% underwent testicular ultrasound as the initial imaging study, all of them had findings suggestive of a benign tumor. 87% had preoperative tumor markers (AFP and BHCG). In 66%, an intraoperative biopsy was done and 98% of the intraoperative biopsies were concordant with the final pathology report. Tumorectomy was performed in 81% of patients and total orchiectomy in the remaining 19%. Six percentage of patients underwent a subsequent orchiectomy. Mean follow-up was 39 months (1-278 months) where no cases of atrophy were observed clinically or on ultrasound. Fertility was not evaluated in this series. CONCLUSIONS: Proper management of BTTs is essential to avoid unnecessary orchiectomies. Preoperative ultrasound associated with intraoperative biopsy seems accurate in identifying benign pathology, thus enabling conservative testicular surgery with safety margins. Based on this multicenter series, we suggest performing an intraoperative biopsy with subsequent tumorectomy preserving healthy testicular tissue in BTT.

The burden of cardiovascular diseases is sharply rising in low- and middle-income countries (LMICs). Along with the increasing rates of cardiovascular risk factors in these regions, there is a growing recognition of the contribution of neglected tropical diseases and other infections. Several cardiac implications of these infections have been reported but have not yet been validated by robust population data. This is in part due to limited access to health care and insufficient data collection infrastructure in many LMICs. Therefore, the true impact of these infections on the cardiovascular system may be underestimated, because of both underdiagnosis and underreporting bias. There is an urgent need to thoroughly delineate the cardiac impact of these conditions with elevated prevalence in LMICs and to propose strategies to reduce the negative consequences of these diseases in health systems with limited resources.

Cysticercosis is a parasitic tissue infection caused by larval cysts of the tapeworm Taenia solium. These larval cysts infect brain, muscle, or other tissue, and are a major cause of adult-onset seizures in most low-income countries with tropical climate. Prevalence it's around 50 million people. Although cardiovascular system is not the most affected, this disease can also be associated with multiple and randomly distributed cysts in the subpericardium, subendocardium and myocardium in up to 25% of infected patients. Most cardiac cysticercosis' cases are asymptomatic, but it can manifest with ventricular arrhythmias and conduction disorders. Area Covered: The "Neglected Tropical Diseases and other Infectious Diseases affecting the Heart" (NET-Heart project) is an initiative by the Emerging Leaders group of the Interamerican Society of Cardiology to systematically review all these endemic conditions affecting the heart. A systematic review was conducted following preferred reporting items for systematic review and meta-analysis guidelines and including articles published in MEDLINE, ScienceDirect, PubMed and LILACS databases. A total of 41 papers were included in this review. Expert Opinion: In the areas of greatest prevalence, unhealthiness and poverty favor the development of this disease, which highlights the need to establish global health policies that reduce morbidity and mortality, economic losses of the affected population, and health costs related to hospitalizations for cardiovascular involvement. Authors provide an algorithm to evaluate the possibility of Cysticercosis' cardiovascular complications.

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 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.

BACKGROUND: Catheter ablation (CA) is indicated as definitive therapy for patients with either typical or atypical atrial flutter (TAFlutter and AAFlutter, respectively) which is unresponsive to medical therapy. There is a paucity of data regarding in-hospital outcomes of patients undergoing CA. METHODS: Retrospective study using the NIS to identify patients ≥18 years who underwent CA between 2015 and 2017. Individuals were identified using ICD-10-CM/PCS for TAFlutter, AAFlutter, and CA. RESULTS: A total of 17,390 patients underwent CA for Aflutter (33% AAFlutter and 67% TAFlutter). The TAFlutter group was younger (mean 65.9 years vs. 67.2 years), with less females (30% vs. 43%, p ≤ 0.001 for both) compared to the AAFlutter group. The TAFlutter group had a higher rate of diabetes, tobacco use, obesity, and chronic obstructive pulmonary disease (p ≤ 0.001 for all). The AAFlutter cohort had increased prior strokes and atrial fibrillation (p ≤ 0.001 for both). The mean CHA2DS2-VASc score was found to be 2.3 in AAFlutter compared to 2.1 in TAFlutter (p ≤ 0.001). There were significantly higher proportions of thromboembolic events, transfusions, and longer length of stay in the TAFlutter group (p ≤ 0.001 for all) with the AAFlutter group having significantly higher rates of cardioversion, implantation of cardiac devices, and increased hospital charges (p ≤ 0.001 for all); no significant difference was found in mortality after controlling for comorbidities. CONCLUSIONS: We found higher complication rates in CA for patients with TAFlutter, but no difference in in-hospital all-cause mortality. Variation in CA depending upon the mechanism of AFlutter may underlie these differences, and warrant further study.

Zika virus infection affects more than 80 countries in the world, mainly those with a tropical climate. Although the most frequent clinical presentation is characterized by rash, conjunctivitis, myalgia, arthralgia and fever, in some cases it is associated with cardiovascular manifestations, such as myocarditis, pericarditis, heart failure and arrhythmias. Furthermore, maternal transmission of the virus generates congenital Zika syndrome, which is associated with cardiac septal defects. Early recognition and treatment of Zika's cardiovascular complications are essential to reduce morbidity and mortality in these patients. There is no specific antiviral treatment or vaccine in humans, so the development of public health strategies to prevent its transmission is of paramount importance. The "Neglected Tropical Diseases and other Infectious Diseases" (NET-Heart project) is an initiative to systematically review all these devastating endemic conditions affecting the heart to spread knowledge and propose algorithms for early diagnosis and treatment.

La pandemia de COVID-19 ha infligido grandes estragos a la población y en especial al personal de salud. Los esfuerzos de reanimación exigen modificaciones potenciales de las guías internacionales existentes de reanimación cardiopulmonar (RCP) debido al elevado índice de contagiosidad del virus SARS-CoV-2. Se considera que hasta 15% de los casos de COVID-19 tiene una enfermedad grave y 5% padece un trastorno crítico con una mortalidad promedio del 3%, la cual varía según sean el país y las características de los pacientes. La edad y las comorbilidades como la hipertensión arterial, enfermedad cardiovascular, obesidad y diabetes incrementan la mortalidad hasta 24%. También se ha informado un aumento reciente del número de casos de paro cardíaco extrahospitalario (PCEH). Aunque el paro cardíaco (PC) puede ser efecto de factores diversos en estos pacientes, en la mayoría de los casos se ha demostrado que el origen es respiratorio, con muy pocos casos de causa cardíaca. Se debe considerar la indicación de iniciar o continuar las maniobras de RCP por dos razones fundamentales: la posibilidad de sobrevida de las víctimas, que hasta la fecha se ha registrado muy baja, y el riesgo de contagiar al personal de salud, que es muy alto.The COVID-19 pandemic is having a large impact on the general population, but it has taken a specially high toll on healthcare personnel. Resuscitation efforts require potential modifications of the present Cardiopulmonary Resuscitation (CPR) international guidelines because of the transmissibility rate of the new SARS-CoV 2 virus. It has been seen that up to 15% of COVID-19 patients have a severe disease, 5% have a critical form of infection and the mean death rate is 3%, although there are significant differences according to the country that reports it and patients' baseline conditions that include age, presence of arterial hypertension, cardiovascular disease, diabetes or obesity. In these high risk subjects, mortality might go up to 24%. There are also reports of a recent increase in out-of-hospital cardiopulmonary arrest (OHCA) victims. Cardiac arrest (CA) in these subjects might be related to many causes, but apparently, that phenomenon is related to respiratory diseases rather than cardiac issues. In this context, the decision to start or continue CPR maneuvers has to be carefully assessed, because of the low survival rate reported so far and the high contagion risk among healthcare personnel.

Chagas disease principally affects Latin-American people, but it currently has worldwide distribution due to migration. Death among those with Chagas disease can occur suddenly and without warning, even in those who may not have evidence of clinical or structural cardiac disease and who are younger than 60 years old. HCN4 channels, one of the principal elements responsible for pacemaker currents, are associated with cardiac fetal reprogramming and supraventricular and ventricular arrhythmias, but their role in chagasic arrhythmias is not clear. We found that a single-dose administration of ivabradine, which blocks HCN4, caused QTc and QRS enlargement and an increase in P-wave amplitude and was associated with ventricular and supraventricular arrhythmias in mice challenged with isoproterenol, a chronotropic/ionotropic positive agent. Continuous treatment with ivabradine did not alter the QTc interval, but P-wave morphology was deeply modified, generating supraventricular arrhythmias. In addition, we found that repolarization parameters improved with ivabradine treatment. These effects could have been caused by the high HCN4 expression observed in auricular and ventricular tissue in infected mice. Thus, we suggest, for the first time, that molecular remodeling by overexpression of HCN4 channels may be related to supraventricular arrhythmias in acute Chagas disease, causing ivabradine over-response. Thus, ivabradine treatment should be administered with caution, while HCN4 overexpression may be an indicator of heart failure and/or sudden death risk.
RESUMEN
Neglected tropical diseases (NTD) are a group of diseases with high prevalence in tropical and subtropical countries. They are associated to poverty and underdevelopment. Due to its high morbimortality, these conditions are considered a health crisis. The impact of these diseases can be worsened by the poor socioeconomic status of the affected countries, most of them under-developed, which affects the health care provided to patients. The morbidity of these diseases is explained by the wide organic impairment that they produce. The cardiovascular system is particularly affected, which explains the high morbimortality of NTD. In this article, we review the key issues of a project elaborated by Emerging Leaders of the Interamerican Society of Cardiology (SIAC), about the cardiovascular impact of NTD: the NET-Heart Project (Neglected Tropical Diseases and other Infectious Diseases affecting the Heart).
Las enfermedades tropicales desatendidas (ETD) constituyen un conjunto de afecciones altamente prevalentes en regiones tropicales y subtropicales, asociadas a pobreza y subdesarrollo. Constituyen una verdadera crisis sanitaria, incapacitando y llevando a la muerte a millones de personas anualmente. Esto se ve potenciado por las dificultades socioeconómicas que cursan estos países, mayormente en vías de desarrollo, lo cual repercute en la calidad de la asistencia sanitaria que pueden proveer a la población. La morbilidad de estas enfermedades se explica por la amplia afectación orgánica que generan. El aparato cardiovascular resulta particularmente afectado, lo que explica en gran medida la morbimortalidad de las ETD.

Abstract Neglected tropical diseases (NTD) are a group of diseases with high prevalence in tropical and subtropi cal countries. They are associated to poverty and underdevelopment. Due to its high morbimortality, these conditions are considered a health crisis. The impact of these diseases can be worsened by the poor socioeconomic status of the affected countries, most of them under-developed, which affects the health care provided to patients. The morbidity of these diseases is explained by the wide organic impairment that they produce. The cardiovascular system is par ticularly affected, which explains the high morbimortality of NTD. In this article, we review the key issues of a project elaborated by Emerging Leaders of the Interamerican Society of Cardiology (SIAC), about the cardiovascular impact of NTD: the NET-Heart Project (Neglected Tropical Diseases and other Infectious Diseases affecting the Heart).
