    Spread of ductal carcinoma in situ into a phyllodes breast tumour: a case report

    Get PDF
    Phyllodes are uncommon fibroepithelial breast tumours. Here, we present the case of a 42-year-old woman who presented to our breast centre with a palpable breast mass, which was initially suspected and treated as fibroadenoma but was finally revealed to be a phyllodes tumour. Histopathological examination identified ductal carcinoma in situ (DCIS) within the entire volume of the fibroepithelial tumour. The literature on these transformations is still limited, and the treatment is not standardised

    How Can Scientific Literature Support Decision-Making in the Renovation of Historic Buildings?:An Evidence-Based Approach for Improving the Performance of Walls

    Get PDF
    Buildings of heritage significance due to their historical, architectural, or cultural value, here called historic buildings, constitute a large proportion of the building stock in many countries around the world. Improving the performance of such buildings is necessary to lower the carbon emissions of the stock, which generates around 40% of the overall emissions worldwide. In historic buildings, it is estimated that heat loss through external walls contributes significantly to the overall energy consumption, and is associated with poor thermal comfort and indoor air quality. Measures to improve the performance of walls of historic buildings require a balance between energy performance, indoor environmental quality, heritage significance, and technical compatibility. Appropriate wall measures are available, but the correct selection and implementation require an integrated process throughout assessment (planning), design, construction, and use. Despite the available knowledge, decision-makers often have limited access to robust information on tested retrofit measures, hindering the implementation of deep renovation. This paper provides an evidence-based approach on the steps required during assessment, design, and construction, and after retrofitting through a literature review. Moreover, it provides a review of possible measures for wall retrofit within the deep renovation of historic buildings, including their advantages and disadvantages and the required considerations based on context

    GM1 as adjuvant of innovative therapies for cystic fibrosis disease

    Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) protein is expressed at the apical plasma membrane (PM) of different epithelial cells. The most common mutation responsible for the onset of cystic fibrosis (CF), F508del, inhibits the biosynthesis and transport of the protein at PM, and also presents gating and stability defects of the membrane anion channel upon its rescue by the use of correctors and potentiators. This prompted a multiple drug strategy for F508delCFTR aimed simultaneously at its rescue, functional potentiation and PM stabilization. Since ganglioside GM1 is involved in the functional stabilization of transmembrane proteins, we investigated its role as an adjuvant to increase the effectiveness of CFTR modulators. According to our results, we found that GM1 resides in the same PM microenvironment as CFTR. In CF cells, the expression of the mutated channel is accompanied by a decrease in the PM GM1 content. Interestingly, by the exogenous administration of GM1, it becomes a component of the PM, reducing the destabilizing effect of the potentiator VX-770 on rescued CFTR protein expression/function and improving its stabilization. This evidence could represent a starting point for developing innovative therapeutic strategies based on the co-administration of GM1, correctors and potentiators, with the aim of improving F508del CFTR function

    A retrospective multicentric observational study of trastuzumab emtansine in HER2 positive metastatic breast cancer: A real-world experience

    Get PDF
    We addressed trastuzumab emtansine (T-DM1) efficacy in HER2+ metastatic breast cancer patients treated in real-world practice, and its activity in pertuzumab-pretreated patients. We conducted a retrospective, observational study involving 23 cancer centres, and 250 patients. Survival data were analyzed by Kaplan Meier curves and log rank test. Factors testing significant in univariate analysis were tested in multivariate models. Median follow-up was 15 months and median T-DM1 treatment-length 4 months. Response rate was 41.6%, clinical benefit 60.9%. Median progression-free and median overall survival were 6 and 20 months, respectively. Overall, no differences emerged by pertuzumab pretreatment, with median progression-free and median overall survival of 4 and 17 months in pertuzumab-pretreated (p=0.13), and 6 and 22 months in pertuzumab-na\uc3\uafve patients (p=0.27). Patients who received second-line T-DM1 had median progression-free and median overall survival of 3 and 12 months (p=0.0001) if pertuzumab-pretreated, and 8 and 26 months if pertuzumab-na\uc3\uafve (p=0.06). In contrast, in third-line and beyond, median progression-free and median overall survival were 16 and 18 months in pertuzumab-pretreated (p=0.05) and 6 and 17 months in pertuzumab-na\uc3\uafve patients (p=0.30). In multivariate analysis, lower ECOG performance status was associated with progression-free survival benefit (p &lt; 0.0001), while overall survival was positively affected by lower ECOG PS (p &lt; 0.0001), absence of brain metastases (p 0.05), and clinical benefit (p &lt; 0.0001). Our results are comparable with those from randomized trials. Further studies are warranted to confirm and interpret our data on apparently lower T-DM1 efficacy when given as second-line treatment after pertuzumab, and on the optimal sequence order

    An exploratory study on the Italian patients' preferences regarding how they would like to be told about their cancer

    No full text
    Goal: Major cross-cultural differences in truth-telling attitudes and practices have been demonstrated. Until recently, in Italy the doctor could conceal both diagnosis and prognosis to seriously ill patients out of beneficence. Signs of change have been reported, but the extent and way patients would be informed is still unknown. The aim of the study was to assess Italian patients' preferences regarding how they would like to be told about their cancer and its treatment. We examined the factor structure of the Measure of Patients' Preferences-Italian version (MPP-It) and whether demographical and medical variables were associated with the dimensions of patients' preferences. Materials and methods: Patients were invited to participate during a visit to the oncology department of the Lecco hospital (Italy) for chemotherapy or follow-up. An Italian version of the MPP-It was administered. Data were analyzed through a factor analysis. Main results: A total of 210 cancer patients agreed to participate. Three main factors were identified: (1) Information (Talking About the Disease). Items in this factor were concerned with the dialogue about the disease and treatment options; (2) Support (The Emotional World of the Patient). These items referred to the supportive and relational aspects of the physician-patient encounter; (3) Care (The Ideal Doctor). These items related to the patients' desires about the doctor's personal attributes. Conclusions : The first two factors, information and support, were comparable to those of similar American and Asian studies. The study suggests a cross-cultural uniformity among cancer patients who appreciate the informative and clearness of the communication aspects as being primarily important, while also giving high points to relationship aspects. The third factor appears unique to the Italian context
