Commentary: The quest for the holy grail continues: Is levosimendan the best choice to support patients with cardiomyopathy requiring cardiac surgery?

There is no much evidence on the use of levosimendan in cardiac surgery in terms of survival advantage after surger

Castanea sativa Mill. Shells Aqueous Extract Exhibits Anticancer Properties Inducing Cytotoxic and Pro-Apoptotic Effects

In this study, chestnut shells (CS) were used in order to obtain bioactive compounds through different extraction procedures. The aqueous extracts were chemically characterized. The highest extraction yield and total phenolic content was obtained by conventional liquid extraction (CLE). Gallic and protocatechuic acids were the main simple phenols in the extract, with 86.97 and 11.20 mg/g chestnut shells dry extract (CSDE), respectively. Six tumor cell lines (DU 145, PC-3, LNCaP, MDA-MB-231, MCF-7, and HepG2) and one normal prostate epithelial cell line (PNT2) were exposed to increasing concentration of CSDE (1–100 µg/mL) for 24 h, and cell viability was evaluated using 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide MTT assay. A reduced rate in cell viability was observed in DU 145, PC-3, LNCaP, and MCF-7 cells, while viability of the other assessed cells was not affected, except for PNT2 cells at a concentration of 100 μg/mL. Furthermore, CSDE—at concentrations of 55.5 and 100 µg/mL—lead to a significant increase of apoptotic cells in DU 145 cells of 28.2% and 61%, respectively. In conclusion, these outcomes suggested that CS might be used for the extraction of several polyphenols that may represent good candidates for alternative therapies or in combination with current chemotherapeutics

Endovascular Reconstruction for Total Aorto-Iliac Occlusion

Objectives: To analyze outcomes following endovascular treatment of total occlusion of the infrarenal aorta and aorto-iliac bifurcation in a multicenter Italian registry. Methods: It is a multicenter, retrospective, observational cohort study. From January 2015 to December 2018, 1306 endovascular interventions for aorto-iliac occlusive disease were recorded in the vascular registry. For this analysis, only patients treated for total occlusion of the infrarenal aorta and aorto-iliac bifurcation were included. Early (<30 days) primary outcomes of interest were technical success and mortality. Late major outcomes were primary and secondary patency and freedom from conversion to open aortic surgery. Results: A total of 54 (4.1%) patients met the inclusion criteria. Total percutaneous revascularization was possible in 41 (75.9%) patients and hybrid (endo plus open) intervention in 13 (24.1%) patients. The kissing-stent-graft technique was used in 45 (83.3%) cases, covered endovascular reconstruction of the aortic bifurcation (CERAB) in 5 (9.2%), and a unibody endograft deployed in 4 (7.4%). Technical success was 98.1% (n = 53). There were no episodes of intraoperative or perioperative vessel rupture. Conversion to open surgery was not necessary, and there were no in-hospital deaths. The median patient follow-up time was 16 months (interquartrile range [IQR], 6-27). The estimated primary patency rate was 95.8% +/- 0.03 (95% confidence interval [CI]: 85.5-98.9) at 1 year, 91.4% +/- 0.05 (95% CI: 76.2-97.2) at 2 years, and 85 +/- 0.08 (95% CI: 64.5-94.6) at 3 years. Cox regression analysis demonstrated that sex (hazard ratio [HR]: 0.96; 95% CI: 0.15-6.23, p = 0.963), extent of the occlusion (HR: 0.28; 95% CI: 0.05-1.46, p = 0.130), calcium score (HR: 1.88; 95% CI: 0.31-11.27, p = 0.490), or type of endovascular reconstruction (HR: 0.80; 95% CI: 0.13-5.15, p = 0.804) did not affect primary patency. Secondary patency was 95.5% +/- 0.04 (95% CI: 78.4-99.2) at 3 years. No patients required late conversion to open surgical bypass. Conclusions: Endovascular reconstruction for total occlusion of the infrarenal aorta and aorto-iliac bifurcation was successful using a combination of percutaneous and hybrid revascularization techniques. Estimated patency rates at 3 years of follow-up are promising and are unaffected by the extent of occlusion or type of revascularization

Scoping review of radiologic assessment and prognostic impact of skeletal muscle sarcopenia in patients undergoing endovascular repair for aortic disease

Objective: The primary objectives of our scoping review were to evaluate the methods used by research groups to assess the incidence of sarcopenia in patients with aortic disease and the extent of the evidence base that links sarcopenia to the survival of patients undergoing elective endovascular aortic repair and to identify the recurring themes or gaps in the literature to guide future research. Methods: A scoping review in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) protocols extension for scoping reviews was performed. The available studies included those fully reported in English (last query, April 30, 2022). The following PICO question was used to build the search equation: “in patients with aortic disease [population] undergoing endovascular repair [intervention], what was the prevalence and prognosis of radiologically defined sarcopenia [comparison] on the short- and long-term outcomes?” Results: A total of 31 studies were considered relevant, and 18 were included in the present scoping review. In brief, 12 studies had focused on standard endovascular aneurysm repair (EVAR), 2 on thoracic EVAR, and 4 on complex EVAR. All but two studies were retrospective in design, and only one study had included patients from a multicenter database. Sarcopenia had generally been defined using the computed tomography angiography (CTA) findings of the cross-sectional area of the psoas muscle at L3 or L4, sometimes with normalization against the height. Overall, despite the heterogeneity in the methods used for its definition, sarcopenia was highly prevalent (range, 12.5%-67.6%). The patients with sarcopenia had had higher rates of mortality (ratio ranged from 2.28 [95% confidence interval, 1.35-3.84] to 6.34 [95% confidence interval, 3.37-10.0]) and adverse events (41% vs 16%; P = .020). Conclusions: Sarcopenia, as identified using computed tomography angiography-based measurements of the skeletal muscle mass, was prevalent among patients undergoing elective EVAR, thoracic EVAR, or complex EVAR. The presence of sarcopenia has been shown to have a negative prognostic impact, increasing the operative risk and has been linked to poorer long-term survival

Early and Midterm Results after Endovascular Repair of Non-infected Saccular Lesions of the Infrarenal Aorta

Objective: The aim was to report short and midterm outcomes of a cohort of consecutive patients treated by endovascular aortic repair (EVAR) for saccular lesion of the abdominal aorta (sl-AA). Methods: This was a multicentre, retrospective, financially unsupported physician initiated, observational cohort study that involved tertiary referral from Italian hospitals. For this study, between January 2010 and December 2020, only those patients treated by EVAR for non-infected sl-AA, namely blister/ulcer like projection and/or penetrating aortic ulcer, were analysed. Primary outcomes of interest were overall survival and freedom from aorta related mortality (ARM). Results: The final cohort included 120 of 3 982 eligible aortic lesions. There were 103 (85.8%) males and 17 (14.2%) females. The median age was 76 years (interquartile range [IQR] 69, 80). Rupture on admission was observed in 10 (8.3%) cases. Early (≤ 30 days) death occurred in two (1.7%) patients. There were five (4.2%) complications requiring surgical re-intervention (iliac limb occlusion n = 4; groin haematoma, n = 1). The median duration of follow up was 20 months (IQR 4, 59.5): the estimated overall survival was 85.5% (standard error [SE] 0.035; 95% confidence interval [CI] 77.3 – 91.1) at 12 months, 78.7% (SE 0.044; 95% CI 69.0 – 86.0) at 36 months, and 74% (SE 0.050; 95% CI 63.2 – 82.5) at 60 months. Only one (0.8%) patient required aortic re-intervention during follow up because of a late endograft infection. The estimated freedom from ARM was 96% (SE 0.050; 95% CI 90.3 – 98.2) at 36 and 60 months. Cox's regression analysis identified that death was associated with age > 70 years (hazard ratio [HR] 1.10; 95% CI 1.04 – 1.17, p = .001), and coronary artery disease (HR 1.14; 95% CI 1.04 – 1.26, p = .006). Conclusion: EVAR for sl-AA proved to be safe and effective. The mortality rate was low for a group of patients known to be at high risk from open repair, and EVAR remained stable with no ARM during midterm follow up, and an acceptably low 0.8% endograft related re-intervention rate

Comparison of aortoiliac repair with iliac branch endoprosthesis versus hypogastric occlusion in aortoiliac aneurysms

BACKGROUND: The CARIBE Study aims to assess the outcome of endovascular repair (EVAR) with iliac branch endoprosthesis (IBE) in patients with aorto-iliac aneurysms extending to iliac bifurcation, comparing these results with those of EVAR with hypogastric occlusion pres¬ ent in the recent published literature. METHODS: Patients with aorto-iliac aneurysms anatomically suitable for EVAR with IBE, are included in the study. RESULTS: Primary safety outcome measure are total and aneurysm related death free survival. Efficacy endpoints include: iliac branch patency, aneurysmal sac exclusion and freedom from reinterventions or conversion to open repair. Patient reported outcomes are evaluated with Walking Impairment Questionnaire (WIQ), International Index of Erectile Function-5 (IIEF-5) and quality of life Euro-Qual EQ-5D Questionnaire. CONCLuSIONS: Comparison with recent hystorical literature obtained in patients with EVAR with HA occlusion will offer data useful for correct information of patients affected by aorto-iliac aneurysms

Cox regression analysis demonstrated that sex (hazard ratio [HR]: 0.96; 95% CI: 0.15-6.23, p = 0.963), extent of the occlusion (HR: 0.28; 95% CI: 0.05-1.46, p = 0.130), calcium score (HR: 1.88; 95% CI: 0.31-11.27, p = 0.490), or type of endovascular reconstruction (HR: 0.80; 95% CI: 0.13-5.15, p = 0.804) did not affect primary patency. Secondary patency was 95.5% ± 0.04 (95% CI: 78.4-99.2) at 3 years. No patients required late conversion to open surgical bypass. Conclusions: Endovascular reconstruction for total occlusion of the infrarenal aorta and aorto-iliac bifurcation was successful using a combination of percutaneous and hybrid revascularization techniques. Estimated patency rates at 3 years of follow-up are promising and are unaffected by the extent of occlusion or type of revascularization
