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.

研究触变成形Ti−Cu合金的力学性能。Ti−Cu(25%,27%,29%Cu,质量分数)锭的制备流程为:先进行电弧熔炼,再在950℃均匀化处理24 h,然后在900℃热锻,最后在1035℃热处理300 s后以8 mm/s的速度触变成形。结果显示,触变成形合金表现出良好的力学强度,但其在拉伸载荷下的塑性一般,在压缩载荷下的塑性尚可。随着Cu含量的增加,包晶Ti_(2)Cu相(转变液相区)的体积分数增加,与α+Ti_(2)Cu相区(转变固相区)相比,其力学强度和塑性更低,导致合金的力学强度和塑性降低。这些结果表明,Ti−Cu合金的力学性能和半固态加工性之间的平衡主要取决于Cu含量。

BACKGROUND Despite the advent of biological drugs, conventional therapy continues to be used in moderate to severe inflammatory bowel disease(MS-IBD). This study hypothesized that as a standard of treatment and the primary alternative to biologics, conventional therapy should present robust effectiveness results in IBD *** To investigate the effectiveness of conventional therapy for *** A systematic review with no time limit was conducted in July 2017 through the Cochrane Collaboration, MEDLINE, and LILACS databases. The inclusion criteria encompassed meta-analyses, systematic reviews, randomized clinical trials, observational and case-control studies concerning conventional therapy in adult patients with MS-IBD, including Crohn's disease(CD) and ulcerative colitis(UC). Corticosteroids(prednisone, hydrocortisone, budesonide, prednisolone,dexamethasone), 5-aminosalicylic acid(5-ASA) derivatives(mesalazine and sulfasalazine) and immunosuppressants [azathioprine(AZA), methotrexate(MTX), mycophenolate, cyclosporine, tacrolimus, 6-mercaptopurine(6-MP)] were considered conventional therapy. The exclusion criteria were sample size below50; narrative reviews; specific subpopulations(e.g., pregnant women,comorbidities); studies on postoperative IBD; and languages other than English,Spanish, French or Portuguese. The primary outcome measures were clinical remission(induction or maintenance), clinical response and mucosal healing. As secondary outcomes, fecal calprotectin, hospitalization, death, and surgeries were analyzed. The quality of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation *** The search strategy identified 1995 citations, of which 27 were considered eligible(7 meta-analyses, 20 individual studies). For induction of clinical remission, four meta-analyses were selected(AZA and 6-MP showed no advantage over placebo,MTX or 5-ASA in CD; MTX showed no statistically significant diffe
