Mitoxantrone pleurodesis to palliate malignant pleural effusion secondary to ovarian cancer

Background  

Advanced ovarian cancer is the leading non-breast gynaecologic cause of malignant pleural effusion. Aim of this study was to assess the efficacy of mitoxantrone sclerotherapy as a palliative treatment of malignant pleural effusions due to ovarian cancer.

Role of regional aortic wall properties in the pathogenesis of thoracic aortic dissection

Objectives. The mechanisms of the location and extension of acute aortic dissection (AD) are only poorly understood. The aim of this study was to compare the cohesion of the non-coronary aortic sinus (NAS) and the ascending aortic wall (AA) using the Dissectometer – a new device for analyses of the mechanical properties of the aorta. Design. The properties of the aortic wall were analyzed with the “Dissectometer” (parameters P7, P8 and P9) in adult patients undergoing aortic root (AR) replacement in two different segments: NAS and AA. The aortic wall thickness (AWT) was measured with a micrometer. Results. Thirty-three adult patients (mean age 65?±?14 years, 80% male) were included in this study. The aortic wall of the NAS was significantly thinner than that of the AA (1.9?±?0.4 vs. 2.3?±?0.4, p?Conclusions. This study shows that the wall of the AR is characterized by a thin but stable wall, whereas AA was found to be weaker despite its greater thickness. This difference might be involved in the development and spreading of aortic dissections.     

Frailty and Mortality Outcomes After Percutaneous Coronary Intervention: A Systematic Review and Meta-Analysis

Background

Frailty has been identified as a risk factor for mortality. However, whether frailty increases mortality risk in patients undergoing percutaneous coronary intervention (PCI) has been controversial. Therefore, we conducted a systematic review and meta-analysis of the frailty measures and mortality outcomes in this setting.

The potential role of nutrition on lens pathology: a systematic review and meta-analysis

Oxidative stress is one of the main mechanisms of lens opacification, and certain nutritional antioxidants are suspected to have a protective effect. To examine the role of these nutritional antioxidants on cataract prevention, we searched major databases and reviewed current evidence regarding the protective effect of nutritive antioxidants. We included observational studies that investigate the association between one or more of the following micronutrients and cataract: vitamin A, vitamin C, vitamin E, lutein, zeaxanthin, α- and β-carotene. Two independent authors extracted data and assessed their quality. We pooled results for overall cataract incidence for all types of cataract and separately for nuclear, cortical, and posterior subcapsular cataract. We did not perform sensitivity analysis. Twenty-five studies were included in the qualitative and 24 in the quantitative part of the study, with a total of 295,821 participants over 30 years old. Results from pooled analysis showed a protective effect of antioxidants on cataract, but not all of them reached statistical significance. Statistically significant results were reached for vitamin C (odds ratio [OR] = 0.88, 95% confidence interval [CI] [0.81, 0.97]), beta-carotene (OR = 0.89, 95% CI [0.83, 0.95]), and lutein and zeaxanthin (OR = 0.92, 95% CI [0.85, 0.99]). We did not find statistically significant results for vitamin E (OR = 0.84, 95% CI [0.70, 1.01]), vitamin A (OR = 0.90, 95% CI [0.80, 1.00]), or alpha-carotene (OR = 0.92, 95% CI [0.85, 1.00]). The present study shows a relation between certain antioxidants and cataract, but further studies, especially interventional, are needed to confirm this hypothesis.
