There are about 3194 clinical studies being (or have been) conducted in Portugal. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The current proposal aims to assess if the combination of Speed of Processing (SoP) training with alpha tACS (α-tACS) is able to increase brain speed of processing as assessed by the Useful Field of View (UFOV) when comparing to SoP training plus sham α-tACS. Moreover, a second aim is to assess if those changes in speed of processing transfer to other cognitive domains, such as memory, language and executive functioning. Furthermore, the mechanisms underlying these interventions will be tested, namely to assess brain connectivity and coherence as assessed by EEG. To that purpose, the aim of the current proposal is to conduct a double-blind, parallel randomized trial assessing the effects of combining SoP with alpha endogenous tACS (either active or sham) in participants with Mild Cognitive impairment (MCI).
Breast cancer is the most commonly diagnosed cancer, with an estimated 2.3 million new cases per year globally. Approximately 90% of these patients will undergo breast surgery with/without radiation (locoregional treatment). Different surgical techniques can be offered to the patient, each leading to completely different aesthetic outcomes. Moreover, the aesthetic outcome could be completely different for patients undergoing the same surgery based on individual patient factors (e.g., age, body habitus). In the CINDERELLA trial, the investigators will be using the (Breast Locoregional (BreLO) AI system (an artificial intelligence-based tool for the classification of aesthetic outcomes and matching data and photographs) integrated into CANKADO (a cloud-based healthcare platform) to create an easy-to-use application that can be used on any electronic device, to simulate visually to the patient the aesthetic outcome of a certain surgery or radiation treatment. In the CINDERELLA trial, the investigators plan to compare whether the application helped fulfil the expectations and lead to a better quality of life compared with the classical approach. In the classical approach (control arm), doctors usually propose a locoregional treatment and explain theoretically how the result will be. Nurses help by explaining further details about the surgery and possible outcomes. In most centres, no photographic evaluation is done, and expectations are not measured. The CINDERELLA trial will help overcome miscommunication and potential boundaries in the patient's or physician's understanding of the potential outcomes of locoregional breast cancer treatment.
Researchers are looking for a better way to treat children who have chronic kidney disease (CKD), which is long-term kidney disease, and proteinuria, a condition in which a person´s kidneys leak protein into the urine. The kidneys filter waste and fluid from the blood to form urine. In children with CKD, the kidney´s filters do not work as well as they should. This can lead to accumulation of waste and fluid in the body and proteinuria. CKD can lead to other medical problems, such as high blood pressure, also known as hypertension. Vice versa, hypertension and proteinuria can also contribute to worsening of CKD. Therefore, the treatment of CKD aims to control blood pressure and proteinuria. There are treatments available for doctors to prescribe to children with CKD and hypertension and/or proteinuria. These include "angiotensin-converting enzyme inhibitors" (ACEI) and "angiotensin receptor blockers" (ARB). Both ACEI and ARB can improve kidney function by helping the renin-angiotensin-aldosterone system (RAAS) to work normally. The RAAS is a system that works with the kidneys to control blood pressure and the balance of fluid and electrolytes in the blood. In people with CKD, the RAAS is often too active, which can stop the kidneys from working properly and cause hypertension and proteinuria. However, ACEI or ARB treatment alone does not work for all patients with CKD as they only target the angiotensin part of the renin-angiotensin-aldosterone system. The study treatment, finerenone, is expected to help control RAAS overactivation together with an ACEI or ARB. So, the researchers in this study want to learn more about whether finerenone given in addition to either an ACEI or ARB can help their kidney function. The main purpose of this study is to learn more about whether finerenone added to either ACEI or ARB can help reduce the amount of protein in the participants' urine more than a placebo. A placebo looks like a treatment but does not have any medicine in it. Participants will also continue to receive their other medications. To see how the treatment work, the doctors will take samples of the participants' urine to measure their protein levels before and during taking treatment and after their last treatment. In addition, blood samples will be taken to monitor kidney function, electrolytes and the amount of finerenone in the blood as well as for other tests. This study will include children with CKD and proteinuria aged from 6 months up to less than 18 years. The participants will take: - either finerenone or the placebo, in addition to - either ACEI or ARB, whichever they take as part of their normal treatment Two visits are required up to 104 days, to check whether a child can take part in the treatment phase of the study. If participants qualify for the treatment phase, they will then undergo treatment for about 180 days. During this time, they will visit the study site at least 7 times. During these visits, the participants will: - have their blood pressure, heart rate, temperature, height and weight measured - have blood and urine samples taken - have physical examinations - have their heart examined by an electrocardiogram and echocardiography (a sonogram of the heart) - answer questions about their medication and whether they have any adverse events , or have their parents or guardians answer - answer questions about how they are feeling, or have their parents or guardians answer - answer question about how they like the study medication, or have their parents or guardians answer The doctors will keep track of any adverse events. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments. The doctors will check the participants' health about 30 days after the participants take their last treatment.
Malignant peritoneal mesothelioma is a rare neoplasm. The most common type, the epithelioid type, has been further divided into histological patterns of tubulo-papillary, acinar, adenomatoid, micropapillary, or solid. Its prognosis is improved by the use of a locoregional treatment combining extensive cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC), which increases survival up to 50 months. Histology is one of the most important prognostic variable that, forms the basis for treatment decisions. However, the prognostic of the epithelioid type varies greatly due to its tumor heterogeneity. It is therefore necessary to find prognostic factors of malignant epithelioid peritoneal mesothelioma in order to better define the therapeutic strategy. Among histological factors, solid growth, tumor necrosis, nuclear atypia, and mitotic count were found to be independent prognostic factors in epithelioid malignant pleural mesothelioma. However, in epithelioid malignant peritoneal mesothelioma (EMPM), these factors were studied in small and heterogeneous series in terms of histological growth and definitions used for histological factors. The present large study was conducted to investigate the prognostic impact of several histologic factors in EMPM. Their prognosis impacts were assessed using overall survival (OS) and progression-free survival (PFS) in EMPM.
A study to evaluate if the randomized addition of venetoclax to a chemotherapy backbone (fludarabine/cytarabine/gemtuzumab ozogamicin [GO]) improves survival of children/adolescents/young adults with acute myeloid leukemia (AML) in 1st relapse who are unable to receive additional anthracyclines, or in 2nd relapse.

Carbohydrates are the nutrient in the diet with the greatest impact on blood glucose. Inadequate carbohydrate counts are associated with higher A1c and greater variations in postprandial blood glucose. Clinical guidelines for the nutritional treatment of diabetes recommend that patients with DM1 learn carbohydrate counting or some similar systematic strategy that allows for better metabolic control. However, despite the recommendations, this is still not a reality for most healthcare services treating individuals diagnosed with DM1.
