RESUMO
Piscine orthoreovirus (PRV) is a pathogen that causes heart and skeletal muscle inflammation in Salmo salar and has also been linked to circulatory disorders in other farmed salmonids, such as Oncorhynchus kisutch and Oncorhynchus mykiss. The virus has a segmented, double-stranded RNA genome, which makes it possible to undergo genetic reassortment and increase its genomic diversity through point mutations. In this study, genetic reassortment in PRV was assessed using the full genome sequences available in public databases. This study used full genome sequences that were concatenated and genome-wide reassortment events, and phylogenetic analyses were performed using the recombination/reassortment detection program version 5 (RDP5 V 5.5) software. Additionally, each segment was aligned codon by codon, and overall mean distance and selection was tested using the Molecular Evolutionary Genetics Analysis X software, version 10.2 (MEGA X version 10.2). The results showed that there were 17 significant reassortment events in 12 reassortant sequences, involving genome exchange between low and highly virulent genotypes. PRV sequences from different salmonid host species did not appear to limit the reassortment. This study found that PRV frequently undergoes reassortment events to increase the diversity of its segmented genome, leading to antigenic variation and increased virulence. This study also noted that to date, no reassortment events have been described between PRV-1 and PRV-3 genotypes. However, the number of complete genomic sequences within each genotype is uneven. This is important because PRV-3 induces cross-protection against PRV-1, making it a potential vaccine candidate.

Atrial fibrillation (AF) is the most prevalent arrhythmia and is related with significant morbidity, mortality and costs. In spite of relevant advances in the prevention of embolic events and rhythm control, little has been done to reduce its prevalence, progression and impact, since it increases with ageing as well as with common risk factors such as alcohol intake, tobacco use and stress as well as with arterial hypertension, diabetes mellitus, heart failure, sleep apnea, kidney failure, chronic pulmonary obstructive disease, ischemic heart disease and stroke, among other important comorbidities. Fortunately, new evidence suggests that lifestyle modifications and adequate risk factors and comorbidities control could be effective in primary and secondary AF prevention, especially in its paroxysmal presentations. This is why a multidisciplinary approach integrating lifestyle modifications, risk factors and comorbidities control, is necessary in conjunction with rhythm or rate control and anticoagulation. Unfortunately, that holistic approach strategy is not considered, is scarcely studied or is subtilized in general clinical practice. The present statement's objectives are to: 1) review the relationship between habits, risk factors and illnesses with AF, 2) review the individual and common physiopathology mechanisms of each one of those conditions that may lead to AF, 3) review the effect of control of habits, risk factors and co-morbidities on the control and impact of AF, and 4) supply guidelines and recommendations to start multidisciplinary and integrative AF treatment.
La fibrilación auricular (FA) es la arritmia más frecuente y se asocia con importante morbilidad, mortalidad y costos. A pesar de los grandes avances en la prevención de eventos embólicos y en el control del ritmo, poco se ha realizado para reducir su prevalencia, progresión e impacto, debido a que incrementa con la edad y con la presencia de múltiples factores de riesgo muy comunes en la población, como obesidad, sedentarismo, alcoholismo, tabaquismo y estrés, así como con hipertensión arterial sistémica, diabetes mellitus, insuficiencia cardiaca, apnea del sueño, enfermedad renal crónica, enfermedad pulmonar obstructiva crónica, cardiopatía isquémica y enfermedad vascular cerebral, entre otra comorbilidad importante. Afortunadamente, nuevas evidencias demuestran que las modificaciones en el estilo de vida y el control adecuado de los factores de riesgo y de la comorbilidad pueden ser efectivos en la prevención primaria y secundaria de la FA, en especial en sus formas paroxísticas; para ello, es necesario un manejo multidisciplinario que integre las modificaciones en el estilo de vida, el manejo de los factores de riesgo y el control de la comorbilidad en el tratamiento de la FA en conjunto con el control del ritmo o de la frecuencia y la anticoagulación. Por desgracia, en la práctica clínica estas estrategias a menudo no se tienen en cuenta, son infrautilizadas y poco estudiadas. Los objetivos del presente posicionamiento son: 1) revisar la relación de los factores de riesgo y la comorbilidad con la FA, 2) revisar los mecanismos fisiopatológicos de cada una de estas condiciones, 3) revisar el impacto del control de los factores de riesgo y de la comorbilidad en el control y en el impacto de la FA, y 4) proporcionar guías y recomendaciones para la puesta en práctica de programas de tratamiento multidisciplinario e integral en pacientes con FA.
RESUMO
Objectives: To assess the effectiveness of four doses of the vaccine against SARS-CoV-2 in the general population and the impact of this on the severity of the disease by age group. Methods: By using data from the health authority public data base, we build statistical models using R and the GAMLSS library to explain the behavior of new SARS-CoV-2 infections, active COVID-19 cases, ICU bed requirement total and by age group, and deaths at the national level. Results: The four doses of vaccine and at least the interaction between the first and second doses were important explanatory factors for the protective effect against COVID-19. The R2 for new cases per day was 0.5644 and for occupied ICU beds the R2 is 0.9487. For occupied ICU beds for >70 years R2 is 0.9195 and with the interaction between 4 doses as the main factor. Conclusions: Although the increase in the number of vaccine doses did not adequately explain the decrease in the number of COVID-19 cases, it explained the decrease in ICU admissions and deaths nationwide and by age group.

Abstract Objective: To know the epidemiological behavior and associations of AF in Mexican population. Material and methods: 8,686 patients from 38 cardiologists participating in REMECAR were analyzed. They were divided by gender and age, the comorbidities studied were obesity, chronic kidney disease (CKD), high blood pressure (HBP), diabetes mellitus (DM), dyslipidemia, stroke, chronic obstructive pulmonary disease (COPD), hypothyroidism, heart failure (HF) and ischemic heart disease (IHD). Program used: IBM SPSS Statistic. Results: AF was diagnosed in 498 patients (5.7%), with higher prevalence in men (6.1% vs. 5.3%) and older age in women (74.3 ± 12.1 vs. 70.5 + -12.3 years, p<0.0001). In those under 60 years, AF was associated in women with HF, in men with CKD, DM, stroke, hypothyroidism and HF. In women older than 60 years, AF was associated with CKD, dyslipidemia, stroke, chronic COPD and HF, in men with CKD, stroke, COPD, hypothyroidism, HF and IHD. AF in women increase the probability 1.13 for obesity, 1.13 for HBP, 2.8 for CKD, 2.9 for COPD, 4.3 for stroke and 6.5 for HF, in men increase the probability 1.05 for HBP, 1.4 for DM, 2.1 for CKD, 2.4 for COPD, 3.0 for hypothyroidism, 4.7 for stroke and 6.0 for HF. Conclusions: AF is a very common arrhythmia, with a higher prevalence in patients attending the cardiology consultation, in men and with an older age of presentation in women. The older the age, the higher the prevalence of AF and comorbidities, HF is the most frequent condition associated with AF.
RESUMO
Objectives: To assess the impact of the initial two-dose-schedule mass vaccination campaign in Chile toward reducing adverse epidemiological outcomes due to SARS-CoV-2 infection. Methods: Publicly available epidemiological data ranging from 3 February 2021 to 30 September 2021 were used to construct GAMLSS models that explain the beneficial effect of up to two doses of vaccination on the following COVID-19-related outcomes: new cases per day, daily active cases, daily occupied ICU beds and daily deaths. Results: Administered first and second vaccine doses, and the statistical interaction between the two, are strong, statistically significant predictors for COVID-19-related new cases per day (R2 = 0.847), daily active cases (R2 = 0.903), ICU hospitalizations (R2 = 0.767), and deaths (R2 = 0.827). Conclusion: Our models stress the importance of completing vaccination schedules to reduce the adverse outcomes during the pandemic. Future work will continue to assess the influence of vaccines, including booster doses, as the pandemic progresses, and new variants emerge. Policy Implications: This work highlights the importance of attaining full (two-dose) vaccination status and reinforces the notion that a second dose provides increased non-additive protection. The trends we observed may also support the inclusion of booster doses in vaccination plans. These insights could contribute to guiding other countries in their vaccination campaigns.

Introducción: El sistema de salud del Perú suele tener deficiencias, así es como desde el 2008, se trabajó en el modelo de Asociaciones Público Privadas en Salud (APP), el cual busca el mejor rendimiento del sistema de salud antes de ser aplicada en el resto de centros hospitalarios parecidos del sistema de salud peruano. Objetivo: Comparar la gestión hospitalaria de un modelo APP y un modelo tradicional en dos hospitales de nivel II-2 de Essalud. Metodología: Investigación mixta, no experimental y transversal realizada en dos establecimientos, Hospital Alberto Barton Thompson (HABT) como modelo APP y Hospital Luis Negreiros Vega (HLNV) como modelo tradicional, durante el periodo de gestión hospitalaria del 2016 al 2018, seis funcionarios públicos y 150 usuarios externos. La gestión hospitalaria fue evaluada mediante la eficiencia hospitalaria, gestión financiera y satisfacción del usuario. Resultados: En eficiencia hospitalaria el HABT presentó rendimiento hora-médico por debajo del estándar (3.31 en el 2018), y menor respecto al HLNV (4.74 en 2018). En la gestión financiera, para ambos modelos de gestión público-privada, se coincide que los planes de adquisiciones deben realizarse anticipadamente, siendo problemáticas comunes: el desconocimiento de planes operativos, vigilancia epidemiológica deficiente e insuficiente fortalecimiento de capacidades y competencias; asimismo, la modalidad APP gasta tres veces más en comparación a la modalidad tradicional. Conclusión: un establecimiento de salud de la modalidad de APP, como el HABT, no parece presentar mejores resultados que un establecimiento de formato tradicional como el HLNV.
Introduction: The Peruvian health system usually has deciencies, This is how, since 2008, we have worked on the model of Public-Private Partnerships in Health (PPP), which seeks the best performance of the health system before being applied in the rest of similar hospital centers of the Peruvian health system. Objective: To compare the hospital management of a PPP model and a traditional model in two Essalud level II-2 hospitals. Methods: Mixed, non-experimental, and cross-sectional research carried out in two establishments, Hospital Alberto Barton Thompson (HABT) as PPP model and Hospital Luis Negreiros Vega (HLNV) as the traditional model, during the hospital management period from 2016 to 2018, six public officials and 150 external users. Hospital management was evaluated through hospital efficiency, nancial management, and user satisfaction. Results: In-hospital efficiency, the HABT presented below-standard medical-hour performance (3.31 in 2018), and lower compared to the HLNV (4.74in2018).Innancialmanagement,forbothmodelsofpublic-privatemanagement,itisagreedthat procurement plans must be carried out in advance, with common problems: ignorance of operational plans, poor epidemiological surveillance, and insufficient strengthening of skills and competencies; likewise, the APP modality spends three times more compared to the traditional modality. Conclusion: A PPP modality health facility, such as the HABT, does not seem to present better results than a traditional format facility such as the HLNV.
RESUMO
Background and aims: Dyslipidaemia is a significant risk factor for cardiovascular disease in the Mexican population. This analysis aimed to describe the baseline LDL-c levels of patients presenting to cardiovascular clinics and evaluate the proportion who achieved their risk-based LDL-c goals as recommended by 2021 ESC prevention guidelines. Methods: The REMECAR registry is an observational study of patients attending a specialized cardiovascular clinic for their first visit. The cardiovascular risk was retrospectively determined using the 2021 ESC guideline stratification and the SCORE2 and SCORE-OP. Results: A total of 5443 patients were included in the analysis. Within this population, 55.96% presented as very high, 39.98% as high and 4.06% as moderate to low risk. 63% of the participants were not on any lipid-lowering treatment at entry, while 12.4% were receiving high-intensity statin therapy. Patients presenting with established atherosclerotic cardiovascular disease had a mean LDL-c of 90.9 ± 40.7 mg/dL. Of these, 14.1% were achieving LDL-c levels of 70-55 mg/dL and 19.3% were achieving LDL-c levels <55 mg/dL. In diabetic patients at very high risk, only 25.7% achieved their LDL-c goal. Finally, in patients without another risk factor and very high-risk evaluated by SCORE2 & SCORE-OP, only 14% of patients achieved their LDL-c goals. Conclusions: An important number of patients were not receiving any lipid-lowering therapy. Furthermore, in those who were, a significant portion did not achieve LDL-c recommended thresholds. Our results underline the urgent need to improve the prescription and optimization of lipid-lowering therapy as the current management appears to be insufficient for achieving optimal recommended goals. Identifying key barriers in lipid management is fundamental to establishing better strategies and health system policies to reduce cardiovascular risk.

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.

BACKGROUND AND AIM: Obesity increases the risk of atrial fibrillation (AF) while it may impact the outcome of patients with AF. The clinical implications of this relationship are not completely clear. We aimed to analyze the association of traditional anthropometric measures of excessive adiposity with 12 month case fatality rate (CFR) in patients with AF. METHODS: This was a multicenter, longitudinal, observational study on adults with documented AF, excluding records of AF secondary to reversible causes. Anthropometric variables were registered at baseline, and a central committee validated the 12 month outcomes. RESULTS: We studied 1193 patients (median age: 69.14 years, 55.2% women). At baseline, rhythm control was established for 476 (39.9%) subjects, while frequency control was offered to 717 (60.1%) participants. The 12 month all-cause CFR was 8.9%. A high basal body mass index (BMI), waist-to-height ratio (WHtR) and waist circumference (WC) were associated with lower CFR in bivariate analyses. In a Cox-proportional hazards model, variables associated with 12 month all-cause CFR were BMI categories (HR: 0.736, 95% CI: 0.584-0.928), chronic heart failure (HR: 1.738, 95% CI: 1.127-2.680), chronic kidney disease (HR: 2.269, 95% CI: 1.162-4.429) and carotid stenosis >50% (HR: 5.342, 95% CI: 1.661-17.181). CONCLUSION: The risk of death at one year in patients with AF is inversely associated with a high BMI and directly associated with the presence of chronic kidney disease, carotid stenosis, and chronic heart failure in this cohort of patients with AF. The causes and implications of this apparent obesity paradox should be addressed in the future.

Sudden cardiac arrest (SCA) and sudden death (SD) continue to be a global public health problem, although the true incidence is unknown, it is estimated that they are responsible for 30% of cardiac origin mortality and may represent 20% of total mortality in adults. Unfortunately, the majority of cases occur in the general population, at the out-of-hospital level, in homes and in people who were not known to have heart disease. Although the majority of SCA victims are considered to be of cardiac origin and more frequent ischemic, it is not possible to rule out other causes only with the clinical diagnosis. Autopsy, histological, and toxicological studies are necessary in all victims of SCA and SD to determine the precise cause of death; when these studies are carried out, causes of non-cardiac origin have been found in up to 40% of victims. The type of arrhythmia responsible for an episode of SCA and SD has changed over the years, now asystole and pulseless electrical activity are detected more frequently than ventricular fibrillation or pulseless ventricular tachycardia. These and other aspects that we consider important in the current behavior of SCA and SD are analyzed in this article.
El paro cardíaco súbito (PCS) y la muerte súbita (MS) continúan siendo un problema de salud pública mundial; aunque su verdadera incidencia se desconoce, se calcula que producen el 30% de la mortalidad de origen cardíaco y pueden representar el 20% de la mortalidad total en los adultos. Desafortunadamente, la mayor parte de los casos se presenta en la población general, de forma extrahospitalaria, en los hogares y en personas que no se conocían portadoras de cardiopatía. Aunque se considera que la mayoría de las víctimas de PCS es de origen cardíaco, y que es más frecuente el isquémico, no es posible descartar otras causas sólo con el diagnóstico clínico. Son necesarios la necropsia y los estudios histológicos y toxicológicos en todas las víctimas de PCS y MS para determinar la causa precisa de la muerte; cuando estos estudios se efectúan se han encontrado causas de origen no cardíaco hasta en 40% de las personas. El tipo de arritmia causante de un episodio de PCS y MS ha cambiado a través de los años; ahora se detectan con mayor frecuencia asistolia y actividad eléctrica sin pulso (AESP) que la fibrilación ventricular (FV) o la taquicardia ventricular sin pulso (TVSP). Estos y otros aspectos de importancia en el comportamiento actual del PCS y la MS se analizan en este artículo.

The recommendations in which the Mexican Society of Cardiology (SMC) in conjunction with the National Association of Cardiologists of Mexico (ANCAM) as well as different Mexican medical associations linked to cardiology are presented, after a comprehensive and consensual review and analysis of the topics related to cardiovascular diseases in the COVID-19 pandemic. Scientific positions are analyzed and responsible recommendations on general measures are given to patients, with personal care, healthy eating, regular physical activity, actions in case of cardio-respiratory arrest, protection of the patient and health personnel as well as precise indications in the use of non-invasive cardiovascular imaging, prescription of medications, care in specific topics such as systemic arterial hypertension, heart failure, arrhythmias and acute coronary syndromes, in addition to emphasizing electrophysiology, interventionism, cardiac surgery and in cardiac rehabilitation. The main interest is to provide the medical community with a general orientation on what to do in daily practice and patients with cardiovascular diseases in the setting of this unprecedented epidemiological crisis of COVID-19.

El tipo de arritmia causante de un episodio de PCS y MS ha cambiado a través de los años; ahora se detectan con mayor frecuencia asistolia y actividad eléctrica sin pulso (AESP) que la fibrilación ventricular (FV) o la taquicardia ventricular sin pulso (TVSP). Estos y otros aspectos de importancia en el comportamiento actual del PCS y la MS se analizan en este artículo.

Sudden cardiac arrest (SCA) and sudden death (SD) continues to be a global public health problem, although the true incidence is unknown, it is estimated that they are responsible for 30% of cardiac origin mortality and may represent 20% of total mortality in adults. Unfortunately, the majority of cases occur in the general population, at the out-of-hospital level, in homes and in people who were not known to have heart disease. Although the majority of SCD victims are considered to be of cardiac origin and more frequent ischemic, it is not possible to rule out other causes only with the clinical diagnosis. Autopsy, histological and toxicological studies are necessary in all victims of SCA and SD to determine the precise cause of death; when these studies are carried out, causes of non-cardiac origin have been found in up to 40% of victims. The type of arrhythmia responsible for an episode of SCA and SD has changed over the years, now asystole and pulseless electrical activity (PEA) are detected more frequently than ventricular fibrillation (VF) or pulseless ventricular tachycardia (pVT). These and other aspects that we consider important in the current behavior of SCA and SD are analyzed in this article.
El paro cardíaco súbito (PCS) y la muerte súbita (MS) continúan siendo un problema de salud pública mundial; aunque su verdadera incidencia se desconoce, se calcula que producen el 30% de la mortalidad de origen cardíaco y pueden representar el 20% de la mortalidad total en los adultos. Desafortunadamente, la mayor parte de los casos se presenta en la población general, de forma extrahospitalaria, en los hogares y en personas que no se conocían portadoras de cardiopatía. Aunque se considera que la mayoría de las víctimas de PCS es de origen cardíaco, y que es más frecuente el isquémico, no es posible descartar otras causas sólo con el diagnóstico clínico. Son necesarios la necropsia y los estudios histológicos y toxicológicos en todas las víctimas de PCS y MS para determinar la causa precisa de la muerte; cuando estos estudios se efectúan se han encontrado causas de origen no cardíaco hasta en 40% de las personas.

We present a small child with febrile peaks and syncopal episodes secundary to ventricular tachycardia, in whom it was eventually possible to demostrate the Brugada Syndrome with a special presentation in the ECG; early repolarization pattern in lead I and a aVL and Brugada pattern during fever in V1-V2. This is, to our knowledge, tha first case with this special ECG presentation in a small child.

La radiosinoviortesis como tratamiento de la artropatía hemofílica, frecuentemente, ofrece excelentes resultados, al reducir grandemente el número de episodios de sangramiento y evitar daños ulteriores a las articulaciones. El Centro de Isótopos desarrolló el fosfato crómico coloidal marcado con Fósforo-32, producto listo para su empleo en pacientes hemofílicos. El objetivo de este trabajo fue evaluar la fuga extrarticular de este radiofármaco utilizado en la radiosinoviortesis en pacientes hemofílicos. Se determinó el porcentaje de fuga extrarticular del radiofármaco en 9 pacientes hemofílicos con sinovitis crónica, a los que se les realizó la radiosinoviortesis en la articulación de la rodilla. La radiactividad se midió, con un contador Geiger-Muller, sobre la rodilla tratada, en sus aspectos lateral, encima y medial; la rodilla contralateral; las cadenas linfáticas inguinales, de ambos lados, y el hígado. Los valores de fuga encontrados posteriormente a la inyección fueron 0,0046 por ciento a los 10 min; 0,0023 por ciento a las 24 horas; 0,1332 por ciento el día 7 y 4,0213 por ciento el día 30. Estos resultados coinciden con los valores comunicados por otros autores y con lo esperado de acuerdo a las características del producto, indican que se ejecutó el proceder adecuadamente y que los pacientes fueron seleccionados correctamente(AU)
Radiosynoviorthesis as a treatment for hemophilic arthropathy often offers excellent results, greatly reducing the number of bleeding episodes and avoiding further damage to the joints. The Isotope Center developed a product, Colloidal Chromic Phosphate labeled with Phosphorus-32, ready for use in hemophiliac patients. Our objective was to evaluate the joint leakage of this radiopharmaceutical use in radiosynoviorthesis in hemophilic patients. The percentage of radiopharmaceutical joint leakage was evaluated in 9 hemophilic patients with chronic synovitis, who underwent radiosynoviorthesis in the knee joint. The radioactivity was measured on the treated knee, in its lateral, above and medial aspects, the contralateral knee, the inguinal lymphatic chains of both sides and the liver, with a Geiger-Muller detector. The leakage values 8203;found after the injection were 0.0046 percent at 10 minutes, 0.0023 percent at 24 hours, 0.1332 percent on day 7 and 4.0213 percent on day 30. These results are agreed with the values reported by other authors and with was expected according to the characteristics of the product, indicatate that the procedure was executed properly and that the patients were correctly selected(AU)
