RESUMO

Extracorporeal membrane oxygenation (ECMO) has emerged as an important intervention for children both preceding and following cardiac surgery. There is a notable lack of comprehensive information regarding neurodevelopmental outcomes. The Norwood procedure and complex biventricular repairs exhibit the highest prevalence of ECMO usage. Examination of the data demonstrates that only 50% of ECMO survivors achieved normative cognitive outcomes, with 40% of those experiencing long-term neurological deficits. It is imperative to conduct robustly designed studies with extended follow-up periods to establish guidelines for neuromonitoring and neuroprotection during ECMO in the field of congenital cardiac surgery.

RESUMO

Pulmonary hypertension (PH) is a chronic and progressive disorder characterized by elevated mean pulmonary arterial pressure, pulmonary vascular remodeling, and the development of concentric laminar intimal fibrosis with plexiform lesions. While rodent models have been developed to study PH, they have certain deficiencies and do not entirely replicate the human disease due to the heterogeneity of PH pathology. Therefore, combined models are necessary to study PH. Recent studies have shown that altered pulmonary blood flow is a significant trigger in the development of vascular remodeling and neointimal lesions. One of the most promising rodent models for increased pulmonary flow is the combination of unilateral left pneumonectomy with a "second hit" of monocrotaline (MCT) or SU5416. The removal of one lung in this model forces blood to circulate only in the other lung and induces increased and turbulent pulmonary blood flow. This increased vascular flow leads to progressive remodeling and occlusion of small pulmonary arteries. The second hit by MCT or SU5416 leads to endothelial cell dysfunction, resulting in severe PH and the development of plexiform arteriopathy.

RESUMO

This review provides an overview of menopausal hormone therapy and pulmonary disease risk, with a focus on the effect of hormone replacement therapy (HRT) on pulmonary function and its relation to lung diseases. This summary is based on authors' knowledge in the field of HRT and supplemented by a PubMed search using the terms "menopause hormone therapy," "asthma", "lung cancer", "chronic obstructive pulmonary disease", "lung function", and "pulmonary hypertension". Available evidence indicates that there is limited research on the role of sex hormones in the susceptibility, severity, and progression of chronic respiratory diseases. However, some studies suggest that the hormonal changes that occur during the menopausal transition may have an impact on pulmonary function and respiratory diseases. Women are in need of convenient access to a safe and effective modality for personalized HRT based on an artificial intelligence (AI)-driven platform that will enable them to receive personalized hormonal treatment through frequent, convenient, and accurate measurements of hormone levels in peripheral blood.
