Degenerative Aortic Stenosis in Women: Challenges and Perspectives

Abstract Degenerative aortic stenosis is currently a public health problem. Affecting the elderly population, this pathology has been showing an increasing prevalence as a direct result of the population aging. In this context, women have a greater life expectancy, corresponding to most of the population with degenerative aortic stenosis. Specific characteristics of this pathology in females are present in the diagnosis, pathophysiology, anatomical aspects, imaging and in therapeutic approach. Women present a more severe disease with less valve calcification than men, more concentric ventricular remodeling, higher transvalvular gradients, and less myocardial fibrosis. Less evident symptoms mean that these patients are referred later for surgical or percutaneous therapeutic treatment. The greater comorbidity presented by females and possibly due to the smaller body surface, bring specific aspects that affect the surgery results, leading to higher mortality rates and, more often, the prosthesis-patient mismatch. Percutaneous valve implantation is a good alternative, with better results in females, when compared to surgery, both in the treatment of native valves and in the treatment of a previously implanted bioprosthesis' dysfunction. The challenges encountered for the treatment of aortic stenosis in women and their possible solutions are described in this article, focusing on the observed difference of aortic stenosis in females and their possible solutions.

Mulheres Médicas: Burnout durante a Pandemia de COVID-19 no Brasil / Women Physicians: Burnout during the COVID-19 Pandemic in Brazil

Resumo 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.

Abstract 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.

Relationship between circulating VCAM-1, ICAM-1, E-selectin and MMP9 and the extent of coronary lesions

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.
