In-Hospital Outcomes in Minimally Invasive Mitral Valve Surgery: First Results in a Brazilian Single Center

引用

Open Journal of Thoracic Surgery 2024年第1期14卷 17-28页

作者： Daniel de Magalhães Freitas João alberto Pansani Max Weyler Nery Stanlley de Oliveira Loyola Maurício Lopes Prudente Giulliano Gardenghi Artur Henrique de Souza Department of Cardiovascular Surgery Encore Hospital Aparecida de Goiania Brazil Anesthesia Clinic (Clianest) Goiania Brazil

Introduction: Treatments for cardiovascular diseases have increasingly evolved with the tendency to offer minimally invasive or transcatheter procedures instead of conventional sternotomy surgery. In this context, we highlight minimally invasive mitral valve surgery (MIMVS), which has been shown to be an increasingly solid option with some superior results when compared to the conventional technique: better pain control, shorter hospital stays, shorter recovery time, shorter readmission rate in the first postoperative year, better aesthetic results, and lower overall cost. Aim: This study aims to evaluate the stages of MIMVS, by primary mitral valve consultation, in our service and compare these results with data from the literature. Methods: All electronic medical records of patients who underwent MIMVS for primary mitral valve injury in the Encore Hospital from January 2020 to February 2023 were analyzed. Tabulation and statistical analysis were performed using the Microsoft Excel® program. Quantitative variables were presented as means, standard deviations. Results: 46 patients were enrolled in our study (Age: 59.1 ± 12.4 years old;60.8% Female, BMI: 26 ± 4.4 Kg/m2, Low risk STS score: 82.6%). The observed 30-day mortality was 2.1%, plastic rate of 23.9%, blood transfusion rate of 41.3%, length of stay in an intensive care bed (ICB) of 3.3 ± 3.3 days and hospital stay of 6.4 ± 5.1 days. Conclusions: We noticed that the MIMVS results carried out in our service agree with data from national and international literature with approximately 1.3 days more hospitalization in ICB.

目的通过网络药理学技术预测酸枣仁复方(Ziziphi spinosae semen formula, ZSSF)对于抑郁症的关键作用靶点,并通过利血平诱导的抑郁斑马鱼模型验证酸枣仁复方治疗抑郁症的作用机制。方法通过TCMSP数据库检索酸枣仁复方的药物作用靶点,利用UniProt数据库对靶点名称进行校正。采用GeneCards、OMIM、NCBI数据库检索抑郁症相关靶点,并对3个数据库的靶点结果进行汇总去比重。利用STRING数据库预测了交集靶点的蛋白质-蛋白质相互作用(protein-protein interaction, PPI)信息,利用Metascape数据库构建进行富集研究,并利用微生信对KEGG和GO的富集结果实现了可视化。通过利血平诱导的斑马鱼抑郁模型进行行为学实验和RT-qPCR实验,验证酸枣仁复方对抑郁症的治疗作用。结果筛选出抑郁症与酸枣仁复方的交集靶点188个,蛋白质-蛋白质相互作用结果显示,酸枣仁复方抗抑郁主要作用于肿瘤坏死因子-α(TNF-α)、血清白细胞介素2(IL-2)、血清白细胞介素6(IL-6)、血清白细胞介素1β(IL-1β)、血清白细胞介素10(IL-10)等靶点,KEGG通路富集分析表明,酸枣仁复方通过TNF信号通路、PI3K-Akt信号通路、cGMP-PKG信号通路等多种信号通路发挥其治疗抑郁症的作用。动物实验结果显示,与利血平组相比,酸枣仁复方高、中、低剂量组斑马鱼在声光刺激下的运动距离显著延长(P<0.05),运动速度显著增快(P<0.01)。RT-qPCR结果显示,与利血平组相比,酸枣仁复方高、中、低剂量给药组斑马鱼脑组织中TNF-α、IL-2、IL-6、IL-1β、IL-10 mRNA表达水平上调(P<0.001)。结论酸枣仁复方通过多成分、多靶点发挥抗抑郁作用,且其抗抑郁作用可能与抑制炎症因子的表达有关。

Fabry Disease: Update, Focusing on Heart Disease by Multimodal Imaging

引用

World Journal of Cardiovascular Diseases 2024年第6期14卷 351-362页

作者： Adrian Espejel-Guzman Emily Rodríguez Valente Fernandez-Badillo Javier Serrano-Roman Aldo Cabello-Ganem Alexis Daniel Aparicio-Ortiz alberto Ramon-Rios Mariali Palacios-Cruz Nilda Espinola-Zavaleta Department of Nuclear Cardiology. National Institute of Cardiology Ignacio Chavez Mexico City Mexico ABC Medical Center IAP Department of Echocardiography Mexico City Mexico

Fabry disease (FD) is a rare X-linked lysosomal accumulation disorder caused by a deficiency in the enzyme alpha-galactosidase A (Gal A), resulting in excessive storage of glycosphingolipids, particularly globotriaosylceramide (Gb3). This leads to cellular dysfunction in various organs, with cardiovascular compromise being the major cause of morbidity and mortality. This study aimed to provide a comprehensive overview of FD focusing on its genetic, epidemiological, clinical, diagnostic, and therapeutic aspects. This study explored the genetic mutations associated with FD, its epidemiology, clinical phenotypes, cardiac manifestations, diagnostic approaches, and current treatment options. Background: FD is caused by mutations in GLA on the X chromosome, with over 1000 identified variants. Neonatal screening and specific studies have shown an increased incidence of FD. The clinical presentation varies between classic and late phenotypes, with cardiac involvement being a major concern, particularly in late-onset FD. Purpose: This study aimed to summarize the current knowledge on FD, emphasizing cardiac involvement, diagnostic modalities, and treatment options. Methods: A literature review of relevant studies on FD, including genetics, epidemiology, clinical presentation, diagnostic methods, and treatment options, was conducted. Results: Cardiac manifestations of FD included left ventricular hypertrophy (LVH), heart failure, arrhythmias, and sudden death. Diagnostic approaches such as electrocardiography, echocardiography, and cardiac magnetic resonance imaging play crucial roles in the early detection and monitoring of cardiac involvement. Enzyme replacement therapy (ERT) and emerging treatments have shown promise in managing FD, although challenges remain. Conclusions: FD remains a challenging condition in cardiology, with under-diagnosis being a concern. Early detection and specific therapy are essential to improve patient outcomes.
