NCT ID: NCT06168864 Completed - Prostate Cancer Clinical Trials

Development of Artificial Intelligence Models for Segmentation and Characterization of Prostate Cancer: a Single-center Retrospective Observational Study.

Start date: January 6, 2020
Phase:
Study type: Observational

Prostate cancer is the second most common cancer in the male population. This pathology represents an oncological and public health problem especially in developed countries, due to a greater presence of elderly men in the population. Medical imaging plays a central role in the staging and restaging of prostate disease. Magnetic resonance imaging (MRI), computed tomography (CT) and positron emission tomography (PET) are among the methods commonly used in normal clinical practice for the characterization of prostate cancer. To date, the study of these images is limited to a qualitative visual analysis, however there is increasing evidence relating to the usefulness of introducing a quantitative (or semi-quantitative) analysis of biomedical images. The current increase in available imaging data, and their quality, allows the application of artificial intelligence methods also in the medical field for the automation of tasks (e.g. automatic segmentation) and classification (e.g. tumor aggressiveness). The extraction of quantitative data, and more generally the study of tumor lesions, requires manual segmentation by one or more doctors. This process requires very long times as each image must be processed individually; furthermore, the result also depends on the level of experience of the doctor carrying out the segmentation and this could create a source of heterogeneity, affecting the reproducibility of the segmentation. AI-based automatic segmentation methods can be applied to medical images for the localization of tumor lesions, thus exceeding the limits of manual segmentation.

NCT ID: NCT06167824 Completed - Prostate Cancer Clinical Trials

Assessment of Predictive Role of [11C] Choline PET/CT on Survival in Prostate Cancer Patients With Biochemical Failure Without Androgen Deprivation Therapy

Start date: June 19, 2014
Phase:
Study type: Observational

Among all the patients who underwent PET/CT with choline at our Institute between 2004 and 2007 to restage the prostatic disease following biochemical recovery of the disease, in this retrospective study the patients previously treated with radical prostatectomy, who present a progressive increase in the PSA value in the absence of hormone therapy and of which there is knowledge of the main clinical and follow-up data, with particular attention to survival data. The PET/CT study with Choline, being part of the normal standard diagnostic work-up of patients, was performed following the normal clinical protocol. With the retrospective analysis of the data, the time elapsed following the prostatectomy operation and the follow-up time after the Choline PET/CT study will be evaluated and patients who died due to prostate cancer will therefore be considered. Prostate cancer-specific survival, calculated as the interval between radical prostatectomy and death due to prostate cancer, will be used as the end point. The differences between prostate cancer-specific survival of patients with a positive choline PET/CT study and patients with a negative choline PET/CT study will be evaluated (log-rank test). Choline PET/CT will be considered positive if pathological findings with significant tracer uptake are identified. In the subpopulation of patients with a positive Choline PET/CT study, survival data will also be evaluated in relation to the site of positivity of the PET/CT study, in particular at the level of local recurrence, in the lymph node or skeletal site.

NCT ID: NCT06167577 Completed - Bipolar Disorder Clinical Trials

Dysbindin-antipsychotics Psychophamarcogenetics: a Mouse-human Translational Study Towards Personalized Healthcare in Bipolar Disorders

DYSBIP
Start date: November 8, 2018
Phase:
Study type: Observational

We will conduct an observational study involving a preliminary long-term follow-up designed to test how dysbindin-1 gene expression can modulate the efficacy of treatments with antipsychotics on clinical and neuropsychological outcomes. We will recruit 150 patients diagnosed with DB who required therapy with an atypical antipsychotic (aripiprazole or quetiapine or olanzapine) in combination with a medication mood stabilizer (lithium or other mood stabilizer), according to the standards of DB treatment. Treatment will be maintained stably for at least 6 months, unless the patient's clinical evolution makes a therapeutic switch inevitable. In light of the data in mice, we will correlate the clinical/neuropsychological response to antipsychotics with the presence of the functional DysBray haplotype of the DTNBP-1 gene, which has in the general population a relatively high prevalence (about 25 percent).

NCT ID: NCT06161389 Completed - Apnea Clinical Trials

Applied Forces During Neonatal Face Mask Ventilation With Different Face-mask Air Cushion Volumes

ForVol
Start date: December 11, 2023
Phase: N/A
Study type: Interventional

Positive pressure ventilation (PPV) is the most important intervention in neonatal resuscitation. During PPV, it is important to hold the face-mask with care, as applying excessive pressure could cause injury to the infant, while insufficient pressure could be a contributor of mask leak and reduced effective ventilation. Application of positive pressure to face structures may trigger a vagally mediated reflex via the trigeminal nerve that innervates the skin of the face leading to apnoea and a decrease in heart rate (TCR, trigeminal-cardiac reflex). In neonatal manikins, ventilation with a partially or fully inflated face mask does not seem to result in differences in mask leak. The force exerted by providers to improve mask seal might result in pressure lesions and in the elicitation of the trigeminal-cardiac reflex. However, information about the applied forces is unknown.

NCT ID: NCT06161233 Completed - Breast Cancer Clinical Trials

NCT ID: NCT06160336 Completed - Clinical trials for Lower Limb Amputation

Transcutaneous Electrical Stimulation in Lower Limb Amputees

Start date: March 14, 2021
Phase: N/A
Study type: Interventional

Current lower limb prostheses support ambulation by absorbing and stabilizing positions during walking. Users of lower limb prostheses rely solely on sensory information provided by the contact between the socket and the residual limb. Restoring sensory feedback could potentially improve their quality of life and participation in daily activities. Despite a high incidence of lower limb amputations, there are few studies in the literature addressing the restoration of sensory feedback in lower limb amputees, particularly studies utilizing invasive techniques. In an effort to overcome these limitations, various non-invasive methods have been tested. Despite resulting benefits such as improved gait symmetry and stability, most non-invasive stimulation systems are non-somatotopic, failing to generate a sensation referred to the patient's missing limb. From the literature, Transcutaneous Electrical Nerve Stimulation (TENS) emerges as a very promising non-invasive and somatotopically-based sensory feedback approach, capable of inducing sensations referred to the amputees' phantom limb. Therefore, the proposed study will involve the use of TENS as a means to stimulate sensitivity and prevent perceptual disturbances associated with the interruption of peripheral nerve structures occurring in individuals undergoing amputation. These disturbances, besides influencing the development of symptoms characterized by neuropathic pain, can impact prosthesis management.

NCT ID: NCT06159933 Completed - Lung Transplant Clinical Trials

Primary Graft Dysfunction, Pronation, Bilateral Lung Transplants

Start date: January 1, 2020
Phase: N/A
Study type: Interventional

Proning manoeuvre as an early treatment for acute severe hypoxic respiratory failure has been implemented recently during the COVID-19 pandemic. This method was proposed more than fifty years ago to improve gas exchange : Proning Severe ARDS (PROSEVA) trial, however, was the milestone which demonstrated mortality benefit in patients with severe ARDS. Nevertheless, few analysis were performed on the effects of the prone position after lung transplantion (LT). The aim of the study is therefore to relate LT primary graft dysfunction (PGD) pathophysiology, which occurs in postoperative setting, to prone-positioning effects on ventilation-perfusion matching, improved lung compliance and clinical outcomes of impairedorgan patients.
