RESUMO
BACKGROUND: Transcatheter aortic valve implantation (TAVI) has had an exponential increase of its indication, being incorporated into the Brazilian Unified Public Health System in 2022, thus requiring assessment of its use in Brazil. OBJETICVE: To assess the factors associated with in-hospital mortality and non-fatal complications in both genders in the Brazilian Registry of Transcatheter Aortic Valve Implantation and New Technologies (RIBAC-NT) population. METHOD: Analysis of the RIBAC-NT database from 2008 to 2022 was performed. Logistic models and machine learning were used for statistical assessment of the association between variables and outcomes. The software R was used and a 5% significance level, adopted. RESULTS: Analysis of 2588 patients (women, 51.2%; in-hospital death, 8.2%). Mortality was associated with procedural complications, of which major vascular complication (VC) and acute kidney injury (AKI) stood out (p<0.001). Major VC occurred in 6% of the patients, with 34% mortality; AKI occurred in 8.8%, with 13% mortality, which increased up to 8 times when AKI coexisted with other complications. Non-fatal complications occurred in 50.5% of all patients, affecting 63% of those with 1st generation (1G) bioprosthesis and 39% of those with 2nd generation (2G) bioprosthesis (p<0,001). Non-femoral access and heart rhythm influenced non-fatal complications in patients with 1G prostheses, while complications in patients with 2G prosthesis associated with the female gender (39.6% vs. 30.4%, p=0.003). CONCLUSION: In-hospital mortality in the RIBAC-NT population was directly associated with procedural complications, mainly major VC and AKI. The occurrence of non-fatal complications differed according to gender and bioprosthesis type.
FUNDAMENTO: O implante valvar aórtico transcateter (TAVI) apresenta crescimento exponencial de suas indicações e foi incorporado ao Sistema Único de Saúde em 2022, sendo necessário avaliar seu uso no Brasil. OBJETIVO: Conhecer os fatores associados a mortalidade e complicações não fatais intra-hospitalares, em ambos os gêneros, na população do Registro Brasileiro de Implante de Bioprótese Aórtica por Cateter e Novas Tecnologias (RIBAC-NT). MÉTODO: Análise do banco de dados RIBAC-NT de 2008 a 2022. Aplicados modelos logísticos e machine learning na avaliação estatística da associação das variáveis com os desfechos, empregando o software R e nível de significância de 5%. RESULTADOS: Analisados 2.588 pacientes (mulheres, 51,2%; óbito intra-hospitalar, 8,2%). Mortalidade associou-se a complicações do procedimento, dentre elas destacam-se complicações vasculares (CV) maiores e insuficiência renal aguda (IRA) (p< 0,001). A CV maior ocorreu em 6%, com 34% de mortalidade; IRA ocorreu em 8,8%, com 13% de mortalidade, que aumentou até 8 vezes quando IRA coexistiu com outras complicações. Complicações não fatais ocorreram em 50,5% do total de pacientes, acometendo 63% daqueles com bioprótese de 1a geração (1G) e 39% daqueles com bioprótese de 2a geração (2G) p<0,001. O acesso não femoral e o ritmo cardíaco influenciaram as complicações não fatais nas próteses 1G, enquanto complicações das próteses 2G associaram-se ao gênero feminino (39,6% vs. 30,4%, p= 0,003). CONCLUSÃO: A mortalidade intra-hospitalar na população do RIBAC-NT associou-se diretamente a complicações do procedimento, principalmente CV maior e IRA. A ocorrência de complicações não fatais diferiu conforme o gênero e o tipo da bioprótese.

BACKGROUND: COVID-19 has placed a tremendous burden on physicians worldwide, especially women physicians, affected by increased workload and loss of quality of life. OBJECTIVE: To assess the effects of the COVID-19 pandemic on the quality of life, burnout and spirituality of Brazilian women physicians directly or indirectly providing care to COVID-19 patients. METHODS: Prospective, observational study performed from July 28 to September 27, 2020, in Brazil, with women physicians from 47 specialities, the most frequent being cardiology (22.8%), with no age restriction. They voluntarily answered an online survey with questions on demographic and socioeconomic characteristics, quality of life (WHOQOL-brief), spirituality (WHOQOL-SRPB), and statements from the Oldenburg Burnout Inventory. Statistical analysis used the R software, beta regression, classification trees, and polychoric correlation matrix, with a 5% of significance level. RESULTS: Of the 769 respondents, 61.6% reported signs of burnout. About 64% reported wage loss of up to 50% during the pandemic. Some reported lack of energy for daily tasks, frequent negative feelings, dissatisfaction with capability for work, and caring for others not adding meaning to their lives. Negative feelings correlated negatively with satisfaction with sexual life and personal relations, and energy for daily tasks. The inability to remain optimistic in times of uncertainty correlated positively with feeling unsafe daily and not acknowledging that caring for others brings meaning to life. CONCLUSION: This study showed a high frequency of burnout among Brazilian women physicians who answered the survey during the COVID-19 pandemic. Nevertheless, they presented with a relatively good quality of life and believed that spirituality comforted and reassured them in hard times.
FUNDAMENTO: A COVID-19 adicionou um fardo enorme sobre os médicos ao redor do mundo, especialmente as mulheres médicas, que são afetadas pelo aumento da carga de trabalho e pela perda da qualidade de vida. OBJETIVO: Avaliar os efeitos da pandemia de COVID-19 na qualidade de vida, burnout e espiritualidade de médicas brasileiras que atendem pacientes com COVID-19 direta ou indiretamente. MÉTODO: Estudo prospectivo, observacional realizado de 28 de julho a 27 de setembro de 2020, no Brasil, com mulheres médicas de 47 especialidades, a mais frequente sendo a cardiologia (22,8%), sem restrição de idade. Elas responderam voluntariamente um questionário online com questões sobre características demográficas e socioeconômicas, qualidade de vida (WHOQOL-brief) e espiritualidade (WHOQOL-SRPB) e enunciados do Oldenburg Burnout Inventory. A análise estatística utilizou o software R, regressão beta, árvores de classificação e matriz de correlação policórica, com nível de significância de 5%. RESULTADOS: Das 769 respondentes, 61,6% relataram sinais de burnout. Cerca de 64% relataram perda salarial de até 50% durante a pandemia. Algumas relataram falta de energia para as tarefas diárias, sentimentos negativos frequentes, insatisfação com a capacidade para o trabalho, e que cuidar de outras pessoas não agregava sentido às suas vidas. Os sentimentos negativos correlacionaram-se negativamente com a satisfação com a vida sexual, a satisfação com as relações pessoais e a energia para as tarefas diárias. A incapacidade de permanecer otimista em tempos de incerteza correlacionou-se positivamente com a sensação de insegurança no dia a dia e com o não reconhecimento de que cuidar de outras pessoas trouxesse sentido à vida. CONCLUSÃO: O presente estudo mostrou uma alta frequência de burnout entre as médicas brasileiras que responderam ao questionário durante a pandemia de COVID-19. Apesar disso, apresentavam uma qualidade de vida relativamente boa e acreditavam que a espiritualidade trazia-lhes conforto e segurança nos momentos difíceis.

RESUMO
Members of the triggering receptor expressed on myeloid cells (TREM) family are associated with atherosclerosis risk and progression. TREML4 is upregulated in the early phase of acute coronary syndrome. We investigated the relationship between the mRNA expression of 13 genes in blood leukocytes, TREML4 polymorphisms, and coronary artery lesion extension (Friesinger index) in patients with coronary artery disease (CAD) (n = 137). TREML4 rs2803495 (A > G) and rs2803496 (T > C) variants and leukocyte mRNA expression were analysed by qRT-PCR. TREML4 expression was higher in patients with major coronary artery lesions than in subjects without or with low and intermediate lesions (p < 0.05). However, TREML4 polymorphisms were not associated with coronary lesion extent. Presence of the rs2803495 G allele was not associated with increased TREML4 mRNA expression. Patients carrying the rs2803496 C allele (TC/CC genotypes) were more likely to express TREML4 mRNA than non-C allele carriers (allele C: OR 7.3, and 95% CI 1.9-27.5, p = 0.03). In conclusion, increased TREML4 mRNA expression in blood leukocytes is influenced by gene polymorphisms and is associated with more severe coronary artery lesions, suggesting its potential as a biomarker of the extent of coronary lesions in patients with CAD.

OBJECTIVES: Inflammatory molecules play a role in the development of atherosclerosis, which is the primary origin of cardiovascular disorders. However, to the best of our knowledge, no study has attempted to investigate the relationship between these circulating molecules and the prediction of cardiovascular risk. The present study aimed to investigate the relationships of vascular cell adhesion molecule-1, intercellular adhesion molecule-1, E-selectin and matrix metalloproteinase 9 serum concentrations with the extent of coronary lesions. METHODS: Seventy-four individuals who were undergoing coronary angiography for the first time for diagnostic purposes were enrolled in this study. The extent of the coronary lesion was assessed using the Friesinger Index, and subjects were classified into four groups: no lesions, minor lesions, intermediate lesions and major lesions. Serum biochemical parameters and serum concentrations of vascular cell adhesion molecule-1, intercellular adhesion molecule-1, E-selectin and matrix metalloproteinase 9 were analyzed. RESULTS: The vascular cell adhesion molecule-1 concentration was higher than 876 ng/mL in individuals with intermediate and major lesions (p<0.001 and p=0.020, respectively). Moreover, logistic regression analysis showed that these patients had an increased risk of having an intermediate lesion (p=0.007). Interestingly, all individuals with major lesions had vascular cell adhesion molecule-1 concentrations higher than 876 ng/mL. No association was found between the concentrations of the other proteins and the Friesinger Index. CONCLUSIONS: Serum vascular cell adhesion molecule-1 may be associated with the extent of coronary lesions. Moreover, it may represent an alternative to improve the cardiovascular risk classification in patients without acute coronary syndrome.

RESUMO
BACKGROUND: Statins have multiple antiatherosclerotic effects, but can reduce blood plasma concentrations of minerals, including zinc. As zinc possesses antiinflammatory and antioxidant effects, low zinc status can promote injuries or inadequate tissue repair in endothelial cells. Metallothionein (MT) expression might modulate responses induced by statins in patients with atherosclerosis. However, research regarding mineral status and the use of statins is scarce. This study evaluated the effects of zinc supplementation on zinc status and expression of the zinc-dependent MT1F and MT2A genes in patients with atherosclerosis treated with rosuvastatin. METHODS: A double-blind, randomized clinical trial was performed with 54 participants treated with 10mg rosuvastatin for 4 months with or without zinc supplementation (30mg/day). Diet, lipid profile, high-sensitivity reactive protein C (hs-CRP), plasma and erythrocyte zinc concentrations, erythrocyte superoxide dismutase (SOD) activity, and MT1F and MT2A genes expression were analyzed before and after intervention. RESULTS: Rosuvastatin therapy was effective in reducing low- and non-high-density lipoprotein, total cholesterol, triglycerides, and hs-CRP levels, independent of zinc supplementation. Additionally, zinc treatment had no effect on SOD enzyme activity (P=0.201), plasma (P>0.671) and erythrocyte (P>0.123) zinc concentrations, or the pattern of MT1F and MT2A genes expression (P=0.088 and P=0.229, respectively). CONCLUSIONS: The effectiveness of rosuvastatin treatment is independent of the effects of zinc supplementation. Moreover, rosuvastatin treatment did not have a significant impact on zinc status or MT1F and MT2A genes expression in patients with atherosclerosis.
