[Prevalence, knowledge and control of arterial hypertension in vulnerable neighborhoods of Argentina: A Cross-sectional Study]. / Estudio de prevalencia, conocimiento y control de la hipertensión arterial en barrios vulnerables de Argentina.

INTRODUCTION: Hypertension (HTN) represents the primary individual risk factor, contributing significantly to the global burden of cardiovascular diseases (CVD). In our country, epidemiological research has highlighted substantial variations in the prevalence of these risk factors across different populations. However, there is a lack of epidemiological studies assessing exclusive cardiovascular risk factors within vulnerable neighborhoods characterized by extremely limited economic resources, sociocultural challenges, and inadequate healthcare access. METHODS: A multicenter cross-sectional observational study was conducted among individuals residing in economically deprived and marginalized communities, including informal settlements and underprivileged neighborhoods. Simple random sampling of households was employed. Blood pressure measurements, anthropometric assessments, and epidemiological, economic, and sociocultural questionnaires were administered. Results encompass prevalence rates, awareness levels, and blood pressure control across diverse regions. Logistic regression was utilized to identify independent variables influencing primary outcomes. RESULTS: A total of 989 participants were analyzed. The overall prevalence of hypertension was 48.2%. About 82% had a body mass index (BMI) >25. Approximately 45.3% had less than 6 years of formal education. Independent association was established between education levels below 6 years and higher hypertension prevalence. Among hypertensive individuals, 44% were unaware of their condition, with only 17.2% achieving control, correlated with having health insurance and a higher educational background. Merely 24% were receiving combined therapy. CONCLUSION: The prevalence of hypertension within vulnerable neighborhoods is alarmingly high, surpassing rates in other social strata. Knowledge, treatment, and control levels of hypertension are suboptimal, comparable to other populations. Inadequate use of combination therapy was observed. This study underscores the urgent need for targeted interventions addressing cardiovascular risk factors in poor areas to mitigate the burden of CVD.

[Complexity theory and the hypertensive patient]. / Teoría de la Complejidad y el paciente hipertenso.

Hypertension is the main cause of death worldwide and the approach that the Family Physician makes of hypertensive patients, given his or her key role as a gateway to the health system, is a crucial determinant in their evolution. On the other hand, Complexity theory contributes to the understanding on how systems grow, adapt and evolve. The hypertensive patient, given his character of biological and social being, can be understood and approached as a complex system. Understanding the characteristics of these systems contributes to considering the patient from another perspective, more satisfactory both for himself and for the professional who assists him. This review analyzes the characteristics of the complex system «hypertensive patient¼ and the tools that allow us to account for and interact with this complexity. An approach from multiple perspectives, migrating from the classic reductionist models to others that take into account the dynamic interrelationships that are at stake, would be a useful strategy for the Family Physician in the challenge of achieving adequate control of blood pressure in his or her patients.

[COVID-19 and its relationship with hypertension and cardiovascular disease]. / COVID-19, hipertensión y enfermedad cardiovascular.

The association between hypertension, diabetes, cardio and cerebrovascular disease and severe and fatal COVID-19, described in different countries, is remarkable. Myocardial damage and myocardial dysfunction are postulated as a possible causal nexus. Frequent findings of elevated troponin levels and electrocardiographic anomalies support this concept. On the other hand, hypotheses in favour and against a deleterious effect of angiotensin converting enzyme inhibitors and angiotensin receptor blockers, a usual treatment for cardiovascular disease, have been raised. There is currently no solid evidence and thus properly designed studies on this subject are urgently needed. In this context, patients with cardiovascular disease should especially avoid being exposed to the virus, should not self-medicate and rapidly seek medical advice should they show symptoms of infection.

Análisis de la producción científica argentina en MEDLINE en el área hipertensión arterial / Analysis of Argentine scientific production in MEDLINE in the area of hypertension

Introducción: La ciencia argentina ha jugado un papel importante en el estudio de la presión arterial. Sin embargo, esta producción científica no ha sido caracterizada. Nos propusimos: 1) analizar la contribución de las publicaciones científicas indizadas en MEDLINE de autores con filiación argentina en el campo de la presión arterial e hipertensión arterial en los últimos 50 años, y 2) determinar las características de las revistas científicas en las cuales se publicaron. Métodos: Se analizaron cuantitativa y cualitativamente 831 publicaciones indizadas en MEDLINE (periodo 1966-2017) de autores de Argentina. Resultados: El número de publicaciones se incrementaron 5,4 veces en los últimos 20 años. El 80% de las publicaciones fueron manuscritos originales y el 15% revisiones. El 65% de las publicaciones abordaron la investigación clínica y el 33% la investigación básica. El promedio de autores por trabajo fue de 6 (89% como primer autor), el 74% pertenecían a instituciones públicas. Las investigaciones se publicaron en revistas editadas en EE. UU. (36%), Reino Unido (27%), Holanda (12%), España (6%) y Argentina (4%). El 18% de las publicaciones fue en revistas con factor impacto >3,88 (primer cuartil). Solo el 5% accedieron a revistas con factor ≥10. El índice SJR promedio fue 1,66. Conclusiones: La producción científica Argentina en MEDLINE en el campo de la presión arterial e hipertensión arterial presentó un crecimiento constante. La gran mayoría son investigaciones originales, dirigidas por investigadores con filiación en instituciones públicas. Mayormente se accede a revistas extranjeras con aceptables índices de calidad

Introduction: Argentine science has played an important role in the study of blood pressure. However, this scientific production has not been classified. We set out (1) to analyse the contribution of scientific publications indexed in MEDLINE of authors with Argentinean academic affiliation in the field of blood pressure and hypertension in the last 50 years and, (2) determine the characteristics of the scientific journals in which they were published. Methods: The 831 indexed MEDLINE publications by authors from Argentina were analysed quantitatively and qualitatively (period 1966-2017). Results: The number of publications has increased 5.4 times in the last 20 years. Eighty percent of the publications were original manuscripts and 15% reviews. Sixty-five percent of the publications addressed clinical research, 33% basic research. The average authors per paper was 6 (89% as first author), 74% belonged to public institutions. The research was published in journals published in the United States (36%), the United Kingdom (27%), the Netherlands (12%), Spain (6%) and Argentina (4%). Eighteen percent of the publications were in journals with impact factor >3.88 (first quartile). Only 5% accessed journals with a factor ≥10. The average SJR index was 1.66. Conclusions: Argentine scientific production in MEDLINE in the field of blood pressure and hypertension showed constant growth. The vast majority is original research, directed by researchers with affiliation to public institutions. Foreign journals are accessed in the main, with acceptable quality indexes

COVID-19, hipertensión y enfermedad cardiovascular / COVID-19 and its relationship with hypertension and cardiovascular disease

La asociación entre patología cardiovascular y mala evolución de la infección por SARS-CoV-2 resulta llamativa. Estudios publicados en diferentes países muestran que la hipertensión, la diabetes, la enfermedad cerebrovascular y la cardiopatía isquémica son marcadamente más frecuentes en los pacientes que requieren cuidados críticos o fallecen por COVID-19. Un posible nexo causal sería el daño y la disfunción miocárdica producidos por el SARS-CoV-2, evidenciado en los frecuentes hallazgos de elevación de la troponina y anormalidades electrocardiográficas. Por otra parte, existen hipótesis a favor y en contra de un posible efecto deletéreo de los inhibidores de la enzima convertidora y los bloqueantes del receptor de angiotensina2 en esta patología, no habiendo actualmente evidencia sólida que respalde contundentemente una u otra, resultando impostergable la necesidad de estudios que diluciden este interrogante. Los pacientes con enfermedad cardiovascular deberían evitar especialmente la exposición al SARS-CoV-2, no automedicarse y consultar rápidamente ante la aparición de síntomas

Rate and factors influencing the conversion of abstracts presented at the argentinian congress of hypertension meetings to indexed full peer-reviewed publications / Proporción y factores que influyen en la conversión de los resúmenes presentados en los congresos argentinos de hipertensión arterial en publicaciones indexadas revisadas por pares

Introduction: Publication rates vary significantly among different scientific meetings, with many abstracts never being published as peer-reviewed articles. This issue has never been investigated in the Hypertension field in Argentina. Our purpose was to determine the proportion of abstracts presented at the Argentinian Congress of Hypertension meetings that were published as full articles in peer-reviewed indexed journals, the time lag to publication and the factors associated with successful publication. Methods: we conducted a PubMed search to identify peer-reviewed publications of abstracts presented at the Argentinian Congress of Hypertension meetings between 2006 and 2015, assessing publication rate along with the time lag to publication. We also extracted information about several abstract characteristics and, for those that got published, we recorded the date of publication and journal name with its impact factor and H index. Predictors of publication were analyzed using a multivariable model. Results: a total of 619 abstracts were presented between 2006 and 2015. The rate of conversion to full-text peer-reviewed articles by June 2017 was 28.1% (95%CI 24.7-31.8%), with a median time to publication of 15.7 months (IQR 8-30.9). On multivariable analysis, the independent predictors of publication were basic science category (OR 5 [95%CI 2.3-10.8], p<0.001), oral presentation (OR 2.8 [95%CI 1.6-4.9], p<0.001) and being an award winner for the presentation (OR 3 [95%CI 1.3-6.8], p=0.01). Conclusion: conversion rate to full peer-reviewed articles of abstracts presented at the Argentinian Congress of Hypertension meetings is far from ideal, with potential areas where efforts should be concentrated to improve dissemination of knowledge

Introducción: El porcentaje de resúmenes que se presentan en reuniones científicas y llegan a publicarse como manuscritos completos en revistas indexadas revisadas por pares es bajo. Este problema no ha sido investigado en el área de la hipertensión en Argentina. Nos propusimos determinar la proporción de resúmenes presentados en los congresos argentinos de hipertensión que llegan a publicarse en revistas indexadas, como artículos completos revisados por pares, el tiempo transcurrido hasta la publicación y los factores asociados a la misma. Métodos: Realizamos una búsqueda en PubMed para identificar las publicaciones en revistas con revisión por pares de los resúmenes presentados en los congresos argentinos de hipertensión entre los años 2006 y 2015, determinando el porcentaje de resúmenes que llegaron a publicarse y el tiempo transcurrido hasta la publicación. Registramos fecha de publicación y revista, con su factor de impacto e índice H. Construimos un modelo multivariable de regresión logística para determinar los factores independientemente asociados a la publicación. Resultados: Entre 2006 y 2015 se presentaron 619 resúmenes. La tasa de conversión de resúmenes en artículos revisados por pares a junio de 2017, fue del 28,1% (IC 95%: 24,7-31,8%) con una mediana de tiempo hasta la publicación de 15,7 meses (RIC: 8-30,9). Los factores predictivos independientes de la publicación fueron: categoría ciencia básica (OR: 5 [IC 95%: 2,3-10,8]; p<0,001), presentación oral (OR: 2,8 [IC 95%: 1,6-4,9]; p<0,001), y haber obtenido un premio al mejor trabajo (OR: 3 [IC 95%: 1,3-6,8]; p=0,01). Conclusión: La tasa de conversión de resúmenes en artículos revisados por pares presentados en los congresos argentinos de hipertensión a publicaciones en revistas indexadas dista de ser ideal, habiéndose identificado áreas donde la concentración de esfuerzos podría mejorar la difusión del conocimiento
