The aim of the study is to follow a group of preschool children from early permanent dentition to determine the prevalence and incidence of caries malocclusions and to investigated the related risk factors as age, gender, ethnic origin and non-nutritive sucking habits, breathing disturbances, allergies, Dietary habits, oral hygiene status and dental care.
Arteriovenous malformations (AVMs) are complex and rare cerebral vascular dysplasia. The main purpose of treatment is to avoid the neurological impairment caused by hemorrhagic stroke. The Spetzler-Martin (SM) grading system is widely used to estimate the risk of postoperative complication based on maximum AVM nidus diameter, pattern of venous drainage, and eloquence of location. Generally, grade I and II are amenable to surgical resection alone. Grade III is typically treated via a multimodal approach, including microsurgical resection, embolization, and radiosurgery (SRS). Grade IV and V are generally observed unless ruptured. However, some previous studies indicated that despite the high rate of poor outcomes for high-level unruptured AVMs, the mortality for high-level unruptured AVMs are likely lower than untreated patients. With the development of new embolic materials and new intervention strategies, patients with high-level AVMs may have more opportunities to underwent more aggressive interventions. The OHAVM study aims to clarify the clinical outcomes for patients with SM grade IV and V AVMs after different management strategies.
Cerebral Arteriovenous malformations (AVMs) are abnormal tangles which are usually believed congenital. AVM can cause different symptoms depending on where it is located, but the most common symptoms are intracranial hemorrhage and seizure. Outcomes of AVM patients can be very different due to factors like the location of lesion, age, sex etc. Generally, more early the intervention was taken, the risk of adverse events would be lower. But the selection of surgical timing for pediatric AVM patients is hard to judge, due to children's cerebral vessels angioarchitecture can be still developing with their age. Some previous studies indicated that there is no difference in intervention outcomes between pediatric and adult AVM patients, so pediatric patients should undergo more aggressive intervention. DOPA study aims to compare the clinical intervention outcomes of both pediatric and adult patients with eloquent region cerebral arteriovenous malformations, helping to determine the treatment strategy.
Rupture of intracranial aneurysms can lead to extensive subarachnoid hemorrhage (SAH), a potentially fatal neurological emergency with mortality rates ranging from 8 to 67%. At present, surgical clipping (SC) and endovascular coiling (EC) are two main treatments for aneurysmal subarachnoid hemorrhage (aSAH), in recent years, the improvements in surgical equipment and techniques have already greatly improved the postoperative safety of patients. However, considering individual differences between patients, some still at risk due to possible complications during hospitalization or after discharge from the hospital, it will no doubt generate a large healthcare burden. This prospective, observational clinical trial (LongTEAM) is to improve the diagnosis and treatment effect and efficiency in this field, reducing mortality, medical costs, and medical burden, while opening up new avenues for interdisciplinary clinical practice and scientific research exploration.
Tumor messenger ribonucleic acid (mRNA) expression levels may have a promising role as potential predictive biomarkers for chemotherapy. Peritoneal carcinomatosis appears to be the most common pattern of metastasis or recurrence and is associated with poor prognosis in gastric cancer patients. Intraperitoneal chemotherapy is widely accepted strategy in the treatment of peritoneal dissemination. In this study, our aim is to evaluate the impact of individualized selection of chemotherapeutics and intraperitoneal combined with system chemotherapy on overall survival, disease free survival, response rate, and safety of advanced gastric cancer patients.
General objectives of the project Defining healthy ageing factors; Setting up content-related bases of the international excellence centre (SLO-ITA) in the field of health of elderly citizens; Raising awareness on the significance of healthy ageing, social inclusion and mobility of less privileged populations (the elderly); Reducing the costs of health care; Connecting the existing health care, social and private entities and improving their mutual coordination.
The study aimed to evaluate the outcomes of bifurcation PCI using two techniques (Culotte vs. DK-Culotte) using data from a retrospective analysis.
Somatostatin receptor(SSTR) was expressed in neuroendocrine tumor cells and SSTR-targeting molecular imaging(68Ga-DOTATATE PET/CT) could be a promising technique to evaluate the primary tumor and metastatic lesions of neuroendocrine tumors with higher accuracy. This prospective study is going to investigate whether radiolabeled somatostatin analogs 68Ga-DOTATATE PET/CT may be valuable for diagnosis, risk stratification, and prognostic evaluation of neuroendocrine tumors and compared it with 18F-FDG PET/CT.
Bladder cancer is a malignant disease that affects a large number of people worldwide. An increase in the incidence of this type of cancer has been observed in recent decades, leading to a growing interest in understanding its risk factors, clinical evolution, and possible treatment approaches. This retrospective study aims to retrospectively analyze a cohort of patients diagnosed with muscle-invasive bladder cancer, in whom, after presentation at multidisciplinary oncology committees, the goal of curing the oncological disease while preserving the bladder is considered. Trimodal therapy (TMT) is the most studied bladder preservation strategy, with oncological outcomes superior to those of isolated therapies (or monotherapies) such as transurethral resection of the bladder tumor (TURBT), radiotherapy, or chemotherapy. TMT consists of complete and maximal TURBT of the bladder tumor, followed by definitive radiotherapy combined with a radiosensitizing agent. Objectives The main objective is to retrospectively analyze the effectiveness and safety of the trimodal approach in our setting. Collecting and analyzing data from patients treated in our service will provide valuable insight into clinical outcomes and treatment tolerability in this context. Materials and Methods - Study Design A retrospective study will be conducted using data from medical records of patients diagnosed with bladder cancer from 2014 to 2022 and treated with radiotherapy in our Radiation Oncology Service. Demographic data, medical history, risk factors, clinical characteristics, treatments received, and clinical outcomes will be collected. - Study Population The study population will include all patients with confirmed diagnoses of non-metastatic muscle-invasive bladder cancer.
The purpose of this study is 1) to characterize T-cell response in patients with atrial fibrillation, and 2) to analyze the changes of T-cell response after radio-frequency catheter ablation of atrial fibrillation. First, immune-phenotyping and cytokine profiling of T cells from patients with atrial fibrillation will performed. Next the difference of T-cell immunity among various type of atrial fibrillation patients will be analyzed. Finally the changes of T-cell response and cytokines after radio-frequency catheter ablation of atrial fibrillation will be assessed.
