Produção Científica Sobre Ecocardiografia Transesofágica por Países Ibero-Americanos / Scientific Output on Transesophageal Echocardiography from Iberoamerican Countries

Fundamento: A ecocardiografia transesofágica (ETE) tem atraído grande atenção e está se tornando um campo científico importante e rapidamente crescente. Objetivo: Analisar a contribuição e as características das publicações científicas sobre ETE na Ibero-América. Métodos: Uma pesquisa bibliográfica foi realizada no PubMed (US National Library of Medicine National Institutes of Health) para identificar publicações científicas sobre ETE indexadas até 1º de maio de 2015. Os termos utilizados na pesquisa bibliográfica incluíram "ecocardiografia transesofágica", "ecocardiograma transesofágico", ecocardiografia transesofágica 3D" e "ecocardiografia tridimensional". Esses termos foram vinculados a cada país ibero-americano. Dados adicionais sobre as revistas de cada publicação científica foram obtidos a partir do SCImago Journal & Country Rank. Resultados: A Ibero-América originou 4% de todas as publicações sobre ETE. O número de publicações da Ibero-América aumentou de zero antes de 1990 a 60 em 2015. A Espanha, o México e o Brasil originaram 75% de todas as publicações da região. Cerca de 30% dos textos completos eram de acesso livre. A maioria das publicações científicas era em inglês. Cerca de 90% das publicações eram relatos de casos ou séries de casos sobre endocardite infecciosa, tumores ou massas cardíacas, doença cardíaca congênita, fontes cardioembólicas de acidente vascular cerebral e cardiologia intervencionista invasiva. A Espanha e a Argentina foram os países que originaram manuscritos com maior probabilidade de serem publicados em revistas estrangeiras. Cerca de 40% das publicações ibero-americanas foram em revistas classificadas no quartil superior das revistas científicas em seu respectivo campo. Conclusões: A produção científica sobre ETE na Ibero-América é limitada, mas vem aumentando. O número e as características das publicações sobre ETE mostram diferenças notáveis entre os países ibero-americanos. (Int J Cardiovasc Sci. 2016;29(6):422-430)

Transesophageal echocardiography (TEE) has attracted great attention and is becoming an important, rapid­progressing scientific field. Objective: To analyse the contribution and characteristics of scientific publications on TEE from Iberoamerica. Methods: A literature search was conducted in PubMed (US National Library of Medicine National Institutes of Health) to identify scientific publications on TEE indexed before May 1, 2015. Terms used for the literature search included "transesophageal echocardiography", "transesophageal echocardiogram", "3D transesophageal echocardiography", and "three­dimensional echocardiography". These terms were combined with each Iberoamerican country. Additional data from the journal of each scientific publication were obtained from the SCImago Journal & Country Rank. Results: Iberoamerica originated 4% of all publications on TEE. The number of publications from Iberoamerica increased from zero before 1990 to 60 in 2015. Spain, Mexico, and Brazil originated 75% of all publications from the region. About 30% of full­texts were freely available. Most of the scientific publications were in English. About 90% of the publications were case reports or case series about infectious endocarditis, tumors or cardiac masses, congenital heart disease, cardioembolic sources of stroke, and invasive interventional cardiology. Spain and Argentina were the countries that originated manuscripts with a higher likelihood of being published in foreign journals. About 40% of Iberoamerican publications were in journals ranked in the top 25% of scientific journals in their field. Conclusions: The scientific production on TEE from Iberoamerica is limited, but is increasing. The number and characteristics of publications on TEE show notable differences between Iberoamerican countries.

Impact of metabolic syndrome on the hospitalization rate of Crohn's disease patients seen at a tertiary care center: a retrospective cohort study.

BACKGROUND/AIMS: Recent studies suggest that markers of mesenteric inflammation, such as increased adipose tissue, may be associated with poor outcomes in Crohn's disease (CD). This study's hypothesis is that CD patients with metabolic syndrome (MetS) have more CD-related hospitalizations than CD patients without MetS. METHODS: We conducted a retrospective cohort study of CD patients seen from 2000 to 2012 at our tertiary care center. We analyzed crude and age-, sex- and duration of CD-adjusted incidence rate ratio (IRR) of CD-related hospitalization of those with MetS versus those without MetS. We also investigated possible associations between individual component conditions of MetS and rate of CD-related hospitalization. RESULTS: A total of 868 CD patients were included. There were 37 (4%) patients with MetS at initial observation. After multi-variable adjustment, patients with MetS had a CD-related hospitalization rate twice that of those who did not have MetS. High triglycerides (TG), low high density lipoprotein (HDL) cholesterol and diabetes mellitus (DM) were associated with increased risk of CD-related hospitalization. CONCLUSIONS: CD patients with MetS have a higher rate of CD-related hospitalization compared to those without MetS. Hypertriglyceridemia, low HDL cholesterol and DM may be good markers of local and systemic inflammation as seen in CD.

Economic evaluations on cardiovascular preventive interventions in Argentina.

Cardiovascular diseases are the main cause of death in Argentina. This article analyzes economic evaluations on cardiovascular prevention for this country. A literature search was conducted in five electronic databases during December 2009. Inclusion criteria were complete economic evaluations addressing at least one cardiovascular health outcome for the Argentinean population. Finally, nine studies were included evaluating 14 comparisons. Interventions oriented to primary or secondary prevention in patients that had undergone coronary angioplasty, with a previous cardiovascular event or equivalents, with a hospitalization for heart failure or general population were evaluated. Bread salt reduction, antihypertensive treatment, mass educational campaigns and polypill strategies could be considered cost effective. The available economic evidence to guide resource allocation in cardiovascular disease in Argentina seems to be scarce and limited.
