NCT ID: NCT05978622 Recruiting - Clinical trials for Diabetic Macular Edema

Observational Study of Adult Participants With Diabetic Macular Edema and Suboptimal Response to Anti-Vascular Endothelial Growth Factor Treated With Dexamethasone Intravitreal Implant

Start date: October 30, 2023
Phase:
Study type: Observational

The dexamethasone 700 μg intravitreal implant (DEX-I) delivers dexamethasone gradually to the retina over time. It is an approved drug for the treatment of DME. This study will assess adult participants with diabetic macular edema (DME) and suboptimal response to anti-vascular endothelial growth factor therapy that are treated with DEX-I in the routine clinical setting. Approximately 327 participants who are prescribed DEX-I by their physicians will be enrolled at approximately 40 sites in approximately 10 countries globally. Participants will be followed for 18 months post-DEX-I implantation according to the routine clinical practice of the prescribing centers. Only one eye per participant will be evaluated in the study. No additional burden for participants in this trial is expected.

NCT ID: NCT05977855 Recruiting - Clinical trials for Behavioral and Psychiatric Symptoms of Dementia

Use of a Diary to Assess and Monitor Behavioral and Psychological Symptoms of Dementia ( BPSDiary )

BPSDiary
Start date: July 1, 2023
Phase: N/A
Study type: Interventional

The goal of this randomized clinical trial is to compare the efficacy of the use of a diary to record behavioral and psychological symptoms of dementia (BPSD) in persons with dementia. The main questions it aims to answer are: - Does the use of a diary lead to a reduction of the caregiver's burden at 3 months, compared with standard care? - Does the use of a diary lead to a reduction of the neuropsychiatric inventory (NPI) score at 3 months, compared with standard care? - Does the use of a diary result in less psychotropic drugs prescribed to the patient at 3 months compared with standard care? - Are physicians and caregivers satisfied with managing patients with the use of a diary? - Does the use of a diary reduce the caregiver's stress related to BPSD at 3 months, compared with standard care? Participants will be randomly assigned to either the use of a diary or a control group. Caregivers in the diary arm will be asked to fill in a diary with BPSD including triggers, severity, day and hour, to be analyzed by physicians to prescribe appropriate pharmacological or non-pharmacological interventions. The control group will receive usual care (i.e., appropriate interventions will be applied after interviewing the caregiver and/or visiting the patient).

The CTO-DENOVO study is a multicenter registry of consecutive patients with de novo CTO undergoing successful CTO recanalization with the use of DCB-only strategy. 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.

NCT ID: NCT05977777 Recruiting - Pancreatic Cancer Clinical Trials

Contrast-enhanced Ultrasound and Pancreatic Lesions

Start date: November 7, 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05977764 Recruiting - Liver Neoplasms Clinical Trials

Multimodal Ultrasound and Focal Liver Lesions (FLLs)

Start date: March 13, 2020
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05977075 Recruiting - Clinical trials for Autism Spectrum Disorder

Group Intervention on Executive Function in Children With Autism Spectrum Disorder

Start date: December 1, 2022
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT05976113 Recruiting - Uterine Cancer Clinical Trials

A Retrospective Study on Multiple Classifier Endometrial Cancer

Start date: July 27, 2023
Phase:
Study type: Observational

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.

NCT ID: NCT05975541 Recruiting - Obesity Clinical Trials

Susceptibility to Infectious Diseases in Obesity

SIDERALE
Start date: October 1, 2023
Phase:
Study type: Observational

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.

NCT ID: NCT05974475 Recruiting - Clinical trials for Lung Neoplasm Malignant

MONDRIAN: Multi-omics Integrative Modelling for Stereotactic Body Radiotherapy in Early-stage Non-small Cell Lung Cancer

MONDRIAN
Start date: September 11, 2023
Phase:
Study type: Observational [Patient Registry]

Stereotactic Body Radiotherapy (SBRT) is a form of high-precision radiotherapy playing a major role in patients diagnosed with early-stage non-small cell lung cancer (NSLCL), especially when surgery cannot be performed. It is a non-invasive, well-tolerated treatment, with an excellent ability to control disease recurrence. However, in some patients, disease response is suboptimal: understanding why this happens may open doors to more aggressive approaches, such as the combination with systemic therapies. Hence, the goal of this observational trial is to understand which clinical, imaging, and biological factors are associated with response to SBRT through the development of complex models. In other words, the main question it aims to answer is: "Will this patient respond to radiation treatment based on the characteristics of their disease?". Participants will be treated according to the best clinical practice standards, in agreement with international, national, and internal guidelines. Researchers will compare data collected from patients treated with SBRT with those collected from a similar group of patients, who will be treated with surgery, to see which factors are actual predictors of response to SBRT, or rather are indicators of more or less aggressive disease behavior.
