    Modest tissue penetrance, nonuniform distribution, andsuboptimalrelease of drugs limit the potential of intracranial therapies againstglioblastoma. Here, a conformable polymeric implant, & mu;MESH,is realized by intercalating a micronetwork of 3 x 5 & mu;mpoly(lactic-co-glycolic acid) (PLGA) edges over arraysof 20 x 20 & mu;m polyvinyl alcohol (PVA) pillars for the sustaineddelivery of potent chemotherapeutic molecules, docetaxel (DTXL) andpaclitaxel (PTXL). Four different & mu;MESH configurations wereengineered by encapsulating DTXL or PTXL within the PLGA micronetworkand nanoformulated DTXL (nanoDTXL) or PTXL (nanoPTXL) within the PVAmicrolayer. All four & mu;MESH configurations provided sustaineddrug release for at least 150 days. However, while a burst releaseof up to 80% of nanoPTXL/nanoDTXL was documented within the first4 days, molecular DTXL and PTXL were released more slowly from & mu;MESH.Upon incubation with U87-MG cell spheroids, DTXL-& mu;MESH was associatedwith the lowest lethal drug dose, followed by nanoDTXL-& mu;MESH,PTXL-& mu;MESH, and nanoPTXL-& mu;MESH. In orthotopic models ofglioblastoma, & mu;MESH was peritumorally deposited at 15 days post-cellinoculation and tumor proliferation was monitored via bioluminescenceimaging. The overall animal survival increased from & SIM;30 daysof the untreated controls to 75 days for nanoPTXL-& mu;MESH and90 days for PTXL-& mu;MESH. For the DTXL groups, the overall survivalcould not be defined as 80% and 60% of the animals treated with DTXL-& mu;MESHand nanoDTXL-& mu;MESH were still alive at 90 days, respectively.These results suggest that the sustained delivery of potent drugsproperly encapsulated in conformable polymeric implants could haltthe proliferation of aggressive brain tumors

    Learning Curve for Ultrasound Assessment of Myometrial Infiltration in Endometrial Cancer Visualizing Videoclips: Potential Implications for Training

    Get PDF
    Background: Diagnostic accuracy for estimating myometrial infiltration by ultrasound in endometrial cancer requires experience. The objective of this study is to determine the learning curve (LC) for assessing myometrial infiltration in cases of endometrial cancer using transvaginal ultrasound (TVS). Methods: Five trainees (one staff radiologist and four fourth-year OB/GYN residents) participated in this study. All trainees had experience in performing TVS, but none of them had specific training on the assessment of myometrial infiltration. Trainees were given one specific lecture about the topic, and then they observed videoclips from 10 cases explained by the trainer. After this, all trainees visualized 45 videoclips of uterine ultrasound scans of endometrial cancer cases. The assessment of myometrial infiltration was based on the subjective impression. Definitive histology was used as a reference standard. Trainees stated whether myometrial infiltration was ≥50% or <50%. LC-CUSUM and standard CUSUM graphics were plotted to determine how many cases were needed to reach competence, allowing a mistake rate of 15%. Results: All trainees completed the study. LC-CUSUM graphics showed that three trainees reached competence at the 33rd, 35th and 36th case, respectively. All three of them kept the process under control after reaching competence. One trainee reached competence but did not maintain it in the cumulative analysis. One trainee did not reach competence. Conclusion: Our study suggests that 30-40 cases would be needed to be trained for assessing myometrial infiltration by TVS by visual interpretation of videoclips by most trainees

    Introduction This article points out the design, methods, development and deployment of the international registry promoted by the AutoInflammatory Disease Alliance (AIDA) Network with the aim to define and assess paediatric and adult patients with immune-mediated scleritis. Methods This registry collects both retrospective and prospective real-world data from patients with non-infectious scleritis through the Research Electronic Data Capture (REDCap) tool and aims to promote knowledge and real-life evidence from patients enrolled worldwide; the registry also allows the collection of standardised data, ensuring the highest levels of security and anonymity of patients' data and flexibility to change according to scientific acquisitions over time. The communication with other similar registries has been also ensured in order to pursue the sustainability of the project with respect to the adaptation of collected data to the most diverse research projects. Results Since the launch of the registry, 99 centres have been involved from 20 countries and four continents. Forty-eight of the centres have already obtained a formal approval from their local ethics committees. At present, the platform counts 259 users (95 principal investigators, 160 site investigators, 2 lead investigators, and 2 data managers); the platform collects baseline and follow-up data using 3683 fields organised into 13 instruments, including patient's demographics, history, symptoms, trigger or risk factors, therapies and healthcare utilization. Conclusions The development of the AIDA International Registry for patients with non-infectious scleritis will allow solid research on this rare condition. Real-world evidence resulting from standardised real-life data will lead to the optimisation of routine clinical and therapeutic management, which are currently limited by the rarity of this ocular inflammatory condition

    Objective: This paper points out the design, development and deployment of the AutoInflammatory Disease Alliance (AIDA) International Registry dedicated to pediatric and adult patients affected by Undifferentiated Systemic AutoInflammatory Diseases (USAIDs). Methods: This is an electronic registry employed for real-world data collection about demographics, clinical, laboratory, instrumental and socioeconomic data of USAIDs patients. Data recruitment, based on the Research Electronic Data Capture (REDCap) tool, is designed to obtain standardized information for real-life research. The instrument is endowed with flexibility, and it could change over time according to the scientific acquisitions and potentially communicate with other similar tools; this platform ensures security, data quality and data governance. Results: The focus of the AIDA project is connecting physicians and researchers from all over the world to shed a new light on heterogeneous rare diseases. Since its birth, 110 centers from 23 countries and 4 continents have joined the AIDA project. Fifty-four centers have already obtained the approval from their local Ethics Committees. Currently, the platform counts 290 users (111 Principal Investigators, 179 Site Investigators, 2 Lead Investigators, and 2 data managers). The Registry is collecting baseline and follow-up data using 3,769 fields organized into 23 instruments, which include demographics, history, symptoms, trigger/risk factors, therapies, and healthcare information access for USAIDs patients. Conclusions: The development of the AIDA International Registry for USAIDs patients will facilitate the online collection of real standardized data, connecting a worldwide group of researchers: the Registry constitutes an international multicentre observational groundwork aimed at increasing the patient cohort of USAIDs in order to improve our knowledge of this peculiar cluster of autoinflammatory diseases

    Abdominal drainage after elective colorectal surgery: propensity score-matched retrospective analysis of an Italian cohort

    Get PDF
    background: In italy, surgeons continue to drain the abdominal cavity in more than 50 per cent of patients after colorectal resection. the aim of this study was to evaluate the impact of abdominal drain placement on early adverse events in patients undergoing elective colorectal surgery. methods: a database was retrospectively analysed through a 1:1 propensity score-matching model including 21 covariates. the primary endpoint was the postoperative duration of stay, and the secondary endpoints were surgical site infections, infectious morbidity rate defined as surgical site infections plus pulmonary infections plus urinary infections, anastomotic leakage, overall morbidity rate, major morbidity rate, reoperation and mortality rates. the results of multiple logistic regression analyses were presented as odds ratios (OR) and 95 per cent c.i. results: a total of 6157 patients were analysed to produce two well-balanced groups of 1802 patients: group (A), no abdominal drain(s) and group (B), abdominal drain(s). group a versus group B showed a significantly lower risk of postoperative duration of stay >6 days (OR 0.60; 95 per cent c.i. 0.51-0.70; P < 0.001). a mean postoperative duration of stay difference of 0.86 days was detected between groups. no difference was recorded between the two groups for all the other endpoints. conclusion: this study confirms that placement of abdominal drain(s) after elective colorectal surgery is associated with a non-clinically significant longer (0.86 days) postoperative duration of stay but has no impact on any other secondary outcomes, confirming that abdominal drains should not be used routinely in colorectal surgery

    No full text
    Scanning electron microscopy (SEM) with energy-dispersive microanalysis (EDS) and energy-dispersive x-ray spectrometry (EDXRS) were used to investigate the composition and microstructure of some Roman coins from the Julius Caesar and Octavianus periods. The samples were Cu-based alloys with different surface conditions. The microstructural examination supported the chemical analysis data, explaining compositional changes from the surface to the bulk. Compositional data confirm the numismatic interpretation: coins issued by Julius Caesar were orichalcum (Cu\u2013Zn alloy) coins whereas asses issued by Octavianus were Cu\u2013Pb\u2013Sn coins

    No full text
    Introduction Literature on parents’ adjustment in families with autism spectrum disorder (ASD) children highlights on one hand that raising a child with ASD represent a higher stressful experience comparing to families of children with other disabilities and families of children with typical development. On the other hand, a recent systematic review on relationship satisfaction of these parents stressed the very lower levels of couple satisfaction in parents raising a child with ASD. Give that, the aim of this study is to investigate the association between relationship satisfaction and parental stress in a sample of parents of ASD children. Method 70 parents were recruited (34 = M and 36 = F) to sign the following self-reports: Parenting stress index-short-form (PSI-SF), to assess stress relative to parental role, and dyadic adjustment scale (DAS), to assess couple satisfaction. Results The analysis showed no differences between mothers and fathers respect to investigated variables. Negative correlations between almost all subscales of the PSI-SF and the subscales of DAS emerged. Moreover, from the regression analysis performed, it can be concluded that the values of the total score of the DAS predicts the PSI-SF total score. Conclusions In accordance with and building on the achievements of previous studies, these data illustrate a positive influence of couple adjustment on parental stress in parents of ASD children, supporting the hypothesis that relationship satisfaction emerge as a protective variables in the process of parental adaptation.
