The primary endpoint is target lesion failure at 6 months. The secondary endpoints are: 1) late lumen loss on follow-up angiography, and 2) minimal lumen area on follow-up intravascular ultrasound.
In order to assess the hysteroscopic, histopathologic, and ultrasonographic aspects of uterine monitoring in postmenopausal breast cancer patients with or without abnormal uterine bleeding (AUB), as well as to calculate the risk of endometrial cancer in women with or without AUB.
The characterization of pancreatic lesions is one of the fundamental steps in the management of pancreatic neoplastic diseases. In terms of a subjective assessment of vascular enhancement in the various examination stages, the use of contrast-enhanced ultrasonography (CEUS) in the study of pancreatic neoplastic disease has been thoroughly investigated. Technology advancements have enabled the development of software that can perform an objective study of the parameters of vascular enhancement and their variations during dynamic CEUS (DCEUS). Currently, the paucity of data regarding the characterization of pancreatic lesions trough DCEUS limit the definition of its role in pancreatic disease. The main purpose of this study is to employ the knowledge in this field trough the characterization of focal pancreatic lesions using DCEUS.
Background and aim: FLLs are common findings in abdominal ultrasound and differential diagnosis between benign and malignant lesions is often challenging, especially in patients with chronic liver diseases. The diagnostic role of CEUS has already been defined by international guidelines when lesions show a typical pattern for hepatocellular carcinoma whereas in case of non-typical contrast enhanced patterns radiologic imaging or liver biopsy are still needed. However, these techniques are more invasive and expensive than ultrasound. Therefore, the aim of this study is to identify D-CEUS and SWE quantitative parameters useful for characterizing FLLs. Study design: Prospective, observational, single-center study Methods: 50 consecutive adult patients with focal liver lesions detectable with B-mode ultrasound will be enrolled in the Unit of Internal Medicine and Gastroenterology of the Policlinico Gemelli. Exclusion criteria will be liver failure, hearth failure, previous locoregional or systemic treatments for FLLs (e.g. ablation, chemoembolization, alcoholization, chemotherapy), known allergy to ultrasound contrast agents. After obtaining informed consent and identifying the target lesion in B-mode ultrasound, patients will undergo CEUS and SWE and, subsequently, to computed tomography/magnetic resonance/biopsy according to international guidelines and current clinical practice. The average, maximum, minimum and standard deviation value of lesion elasticity in KPa will be calculated using SWE. Three consecutive SWE acquisitions will be performed both for the lesion and for the liver parenchyma and the average value of the three measurements will be considered. The CEUS will allow the construction of signal intensity curves as a function of time in a specific area of interest drawn manually. From these curves a series of quantitative parameters related to the flow and volume of blood will be extrapolated and in particular: peak intensity, PI (in Arbitrary Units, AU); time to peak, TP ( in seconds); area under the time curve, AUC (in AU); slope of the wash-in curve, Pw (in AU per second); average transit time, MTT (in seconds). In addition, the personal, clinical and laboratory data necessary to determine the hepatological scores of disease severity such as MELD and Child-Pugh will be collected. The study has an expected duration of one year.
This is a multicenter, prospective, non-randomized, open-label, phase 2 clinical study to evaluate the efficacy and safety of tislelizumab in patients with de novo Hodgkin Lymphoma deemed ineligible to frontline chemotherapy.
Autism is a developmental disorder characterized by difficulties in social communication, repetitive behaviors, and social interaction. A key aspect of autism concerns executive functions, which are a set of cognitive processes that regulate attention, planning, inhibition, and impulse control. These functions are often impaired in children with autism, affecting their learning and daily functioning. The present protocol aims to test the first absolute and then comparative effectiveness of two executive function development programs: the "APISMELA" training and the "UNSTUCK & ON TARGET! SECOND EDITION". Two groups will be held at the same time and will conduct the two programs in reverse order. In fact, the protocol is divided into two phases. Participants subjected to the APISMELA group, finished the intervention sessions will conduct an interim evaluation and then begin the intervention phases of the UNSTUCK & ON TARGET! SECOND EDITION protocol. Participants subjected to the UNSTUCK & ON TARGET! SECOND EDITION group, finished the intervention sessions will conduct an interim evaluation and then begin the intervention phases of the APISMELA protocol. Group intervention programs were chosen for two reasons: group intervention compared with individual intervention have lower costs for patients and their families and thus higher overall social acceptability. The second is that group intervention within the social-constructivist paradigm, to which the two chosen programs belong, becomes a fundamental resource for stimulating that augmentative learning that is a source of development on the cognitive and conceptual levels for human beings.
The purpose of this study is to investigate whether subthreshold treatment with micropulsed laser can be effective in resolving macular edema in patients with inherited retinal dystrophy. Visits will be performed after 1, 3, 6, 9, 12, 18, and 24 months after treatment. Laser treatment will be performed on the day of the first visit, and its repetition at subsequent visits between months 3 and 12 will be evaluated. Evaluations of treatment effects will include: - comprehensive ophthalmologic examination - multifocal electroretinogram - OCT examination - OCT-angiography examination - retinography Primary endpoint. - central retinal thickness, measured by OCT
Endometrial cancer is not a single entity but rather a very heterogeneous group of diseases. Historically, endometrial cancer patients have been classified as endometrioid (type I) or non-endometrioid (type II) according to the dualistic Bokhman model- However, this approach has been limited in accurately predicting prognosis and guiding treatment owing to heterogeneity within subtypes, inadequate incorporation of molecular and genetic information, and high interobserver variability . In the last ten years, after the publication of The Cancer Genome Atlas (TCGA)[5], the molecular classification of endometrial cancer into four molecular subtypes [(i) POLE/ultramutated group (POLE mutated), (ii) mismatch repair deficiency/microsatellite-instable, hypermutated group (MMRd/MSI-H), (iii) copy-number-high, TP53-mutant (CNH/p53abn), and (iv) copy-number-low, TP53-wild-type (CNL, or No Specific Mutational Profile [NSMP])] has rapidly gained interest. Recently, the European Societies of Gynaecological Oncology, Radiotherapy and Oncology, and Pathology (ESGO-ESTRO-ESP), the European Society of Medical Oncology (ESMO), the National Comprehensive Cancer Network (NCCN), and the new 2023 International Federation of Gynecology and Obstetrics (FIGO) staging system have promoted the use of (surrogate) molecular classification. Retrospective studies supported the value of adopting molecular classification to offer reliable data on prognostication and adjuvant treatment decisions. Although no prospective data are available, current guidelines promote the use of molecular profiles to tailor adjuvant treatment after surgery. As only a few retrospective studies have investigated the association between molecular profiles and response to various adjuvant treatments, it is important to note that data are limited. Interestingly, the growing adoption of molecular profiling led to the detection of a subgroup of tumors called multiple classifiers, characterized by multiple (two or three) molecular features. According to the guidelines, tumors with a POLE mutation should be considered POLEmut, regardless of other molecular features, whereas MMRd/MSI-H tumors with a p53 abnormality should be considered MMRd/MSI-H. Data on these patients is limited and fragmentary. The aforementioned consensus is based solely on a large retrospective cohort of multiple classifiers collected by Leon-Castillo et al.. Hence, to fill this literature gap, the investigators designed this retrospective study, which aimed to collect multiple classifiers patients to improve knowledge on this emerging category.
The role of intestinal microbiota is becoming ever more important in the context of obesity, type II diabetes (T2D), and infectious disorders as represented by the emerging discipline "therapeutic microbiology". The gut microbiota is strictly interconnected with obesity and T2D playing also an important role in immune system regulation. Obesity and diabetes can lead to chronic inflammation, which results in the secretion of pro-inflammatory cytokines like IL-6, IL-1, and TNF-alpha, causing immune system alteration which predisposes patients with obesity and T2D to chronic infections. Therefore, the principal aim of the study is to investigate changes in gut microbiota composition between patients with chronic infections or not, so as to attribute to specific phyla the formation of the infections in these patients.
The purpose of this clinical study is to evaluate the safety and efficacy of treating periodontal disease with the STERIFY GEL medical device in combination with SRP procedure, in terms of periodontal pocket healing. Efficacy will be compared with the use of the nonsurgical SRP technique alone, which is considered a gold standard treatment for periodontitis, with the aim of observing improved results when using the STERIFY GEL device. The study is prospective, split-mouth.STERIFY GEL will be administered into the periodontal pockets of one or two segments of patients undergoing whole-mouth extended SRP, with the contralateral segments serving as controls (split-mouth), in a single session.
