ABSTRACT

Vulvar leiomyomas are extremely rare smooth muscle tumors that are easily mistaken for other lesions, as the differential diagnosis must consider a wide spectrum of benign and malignant lesions. We present the case of a 52-year-old woman with a three-year history of progressive abdominal distension and pain and an enlarging vulvar mass distorting the labia majora and causing gait disturbance. Imaging confirmed an enormous pelvic mass originating in the uterus, compatible with a leiomyoma/sarcoma, and large perineal and vulvar masses with similar characteristics. Histopathology after surgical removal revealed benign abdominal, vulvar, and perineal leiomyomas. This case highlights the rarity and diagnostic challenges of extra-uterine leiomyomas, particularly those in the vulvar region.

ABSTRACT

INTRODUCTION AND OBJECTIVES: Cardiogenic shock (CS) complicates 5-10% of cases of myocardial infarction (MI). Whether glycoprotein IIb/IIIa inhibitors (GPIs) are beneficial in these patients is controversial. Our aim is to assess the prognostic impact of GPI use on in-hospital mortality and outcomes in patients with MI and CS undergoing percutaneous coronary intervention (PCI). METHODS: Between October 2010 and December 2019, 27578 acute coronary syndrome (ACS) patients were included in the multicenter Portuguese Registry of Acute Coronary Syndromes. Of these, 357 with an MI complicated by CS were included in the analysis and grouped based on whether they received GPI therapy (with GPI, n=107 and without GPI, n=250). The primary endpoint was in-hospital mortality. Secondary endpoints included successful PCI and in-hospital reinfarction and major bleeding. RESULTS: Demographics and cardiovascular risk factors did not differ between groups. ST-elevation MI patients were more likely to receive GPIs (95% vs. 83%, p=0.002). In-hospital mortality was similar between groups (OR 1.80, 95% CI 0.96-3.37). Only age and the use of inotropes or intra-aortic balloon pump were predictors of mortality. Also, no differences between groups were noted for successful PCI (OR 0.33, 95% CI 0.62-4.06), reinfarction (OR 0.77, 95% CI 0.15-3.90), or major bleeding (OR 1.68, 95% CI 0.75-3.74). CONCLUSION: The use of GPIs in the context of MI with CS did not significantly impact in-hospital outcomes.

ABSTRACT

Precision medicine has recently become widely advocated. It revolves around the individual patient, taking into account genetic, biomarker, phenotypic or psychosocial characteristics and uses biological, mechanical and/or personal variables to optimise individual therapy. In silico testing, such as the Virtual Physiological Human project, is being promoted to predict risk and to test treatments and medical devices. It combines artificial intelligence and computational modelling to select the best therapeutic option for the individual patient.

ABSTRACT

BACKGROUND: Among patients presenting with an acute coronary syndrome, those with previous coronary artery bypass grafting are a particular subset. AIMS: The purpose of this study was to investigate the prognostic impact of previous coronary artery bypass grafting in acute coronary syndrome patients and to identify the current trends in their clinical management. METHODS: We performed a cohort analysis of patients prospectively enrolled in the Portuguese Registry of acute coronary syndrome between 2010-2019 with known previous coronary artery bypass grafting status. The co-primary endpoints were in-hospital and one-year mortality. RESULTS: A total of 19,334 (962 coronary artery bypass grafting and 18,372 non-coronary artery bypass grafting) and 9402 (479 coronary artery bypass grafting and 8923 non-coronary artery bypass grafting) patients were included in the analyses of in-hospital and mid-term outcomes, respectively. Coronary artery bypass grafting patients were older and had a higher incidence of comorbidities. They were less likely to undergo invasive angiography (74.9 vs 84.6%, p<0.001), but were equally likely to receive dual antiplatelet therapy (91.0 vs 90.8%, p=0.823). In-hospital mortality was similar between groups (3.6 vs 3.4%, p=0.722). Unadjusted one-year mortality was higher in the coronary artery bypass grafting group (hazard ratio 1.48, 95% confidence interval 1.09-2.01, p=0.012), but similar in both groups after propensity-matching and multivariate analysis (hazard ratio 0.63, 95% confidence interval 0.37-1.09, p=0.098). CONCLUSIONS: Among patients with acute coronary syndrome, a previous history of coronary artery bypass grafting was associated with a high burden of comorbidities and a high-risk profile but was not an independent predictor of adverse events. Treatment decisions should be made on a case-by-case basis, and should not be based on previous coronary artery bypass grafting status alone.

ABSTRACT

Emerging pollutants are an essential class of recalcitrant contaminants that are not eliminated from water after conventional treatment. Here, a photocatalytic microporous membrane based on polyvinylidene difluoride-co-trifluoroethylene (PVDF-TrFE) with immobilised TiO2 nanoparticles, prepared by solvent casting, was tested against representative emerging pollutants. The structure and composition of these polymeric membranes were characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy, porosimetry, and contact angle goniometry. The nanocomposites exhibited a porous structure with a uniform distribution of TiO2 nanoparticles. The addition of TiO2 did not change the structure of the polymeric matrix; however, it increased the wettability of the nanocomposite. The nanocomposites degraded 99% of methylene blue (MB), 95% of ciprofloxacin (CIP), and 48% of ibuprofen (IBP). The microporous nanocomposite exhibited no photocatalytic efficiency loss after four use cycles, corresponding to 20 h of UV irradiation. The reusability of this system confirms the promising nature of polymer nanocomposites as the basis for cost-effective and scalable treatments of emerging pollutants.

ABSTRACT

INTRODUCTION: Breast cancer is the second leading cause of cancer death among women and the median survival of metastatic breast cancer (MBC) has remained, for many decades, at two to three years after diagnosis. Eribulin mesylate is a nontaxane inhibitor of microtubule dynamics and the only cytotoxic agent in the last decade to improve overall survival in heavily pretreated patients with MBC. Eribulin was approved for the treatment of MBC in 2010 by the FDA in patients that received at least two prior chemotherapy regimens and as second-line treatment in 2011 by EMA. In both cases prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting. AREAS COVERED: This manuscript reviews the current available data on the use of this important cytotoxic agent including its pharmacology, pharmacokinetics, clinical efficacy, safety, and potential economic factors as well as ongoing clinical trials and main areas of research. EXPERT OPINION: Eribulin mesylate is a novel microtubule dynamics inhibitor compound important for the management of MBC and can be used for the treatment of patients who have previously received one/two chemotherapeutic regimens for metastatic disease and whose prior therapy included an anthracycline and a taxane. It's toxicity profile is acceptable and presents several favorable features namely a low probability of drug-drug interactions in the clinical setting, easy administration as bolus, low hypersensitivity chances and full tolerability in renal dysfunction patients. Eribulin is currently being evaluated as first-line treatment for MBC, in the adjuvant/neoadjuvant setting alone and in combination with a variety of agents, particularly biologic treatments. Future research is needed to optimize the role of eribulin in the treatment of MBC.

ABSTRACT

Breast cancer is the most common malignant neoplasm in the world among women. As a result of the dissemination of population screening programmes, about half of non-metastatic breast cancers are now diagnosed at stage I. 10-15% of T1abN0 tumours over-express human epidermal growth factor (HER-2). These tumours have a globally excellent prognosis, however, treatment with chemotherapy and/or targeted therapy may further improve outcomes in selected cases. In this article, we will review studies with information on prognosis and benefit of adjuvant therapy for T1abN0 HER-2+ breast cancer.
