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 high energy nutritional supplement Resource® Energy is approved for human nutritional support in various clinical conditions, yet it has been used off-label to alleviate the effects of hunger during bowel preparation for colonoscopy. Its impact in mucosa visualization quality and hunger alleviation is unknown. The product is liquid and nutritious but it is not transparent, thus it is conceivable that it could alleviate the discomfort of hunger during the preparation but possibly compromising mucosa visualization. In this study, participants who will undergo a colonoscopy (requested for an explicit medical indication) will take two bottles of the nutritional supplement during the usual bowel preparation. The quality of mucosal visualization and the participants opinion regarding satiety and product tolerance during bowel preparation will then be analysed.
The aims of this study are to: - Determine the AVF (arteriovenous fistula) survival of patients submitted to MuST compared to those submitted to RL (rope-ladder). - Determine the AVF (arteriovenous fistula) complication rate of patients submitted to MuST compared to those submitted to RL (rope-ladder). - Analyze the intensity of pain perceived by the patient with each cannulation technique under study.
The objective of this study is to generate expert consensus statements on the definitions of success and failure and its influencing factors in Post-graduate medical education.
The objective of the study is to understand if Qigong may be useful in controlling the psychological state of participants in relative social isolation (during Covid-19 governmental imposed isolation procedures) The sessions are conducted live by the internet by a professional instructor-therapist with the duration of 2 months and a regular minimum of 2 sessions a week.
This study aims to assess the immediate effects of action observation therapy on the cervical muscles' strength, pain intensity, tactile acuity and pain pressure threshold in individuals with chronic nonspecific neck pain.
The main objective of this study is: • To evaluate the immediate hypoalgesic effect of an aerobic exercise session of different intensities in patients with chronic low back pain; The secondary objective is: • To explore whether pain intensity, level of physical activity, functionality, catastrophizing, kinesiophobia, anxiety and depression interfere with the immediate hypoalgesic effect of exercise.
The present investigation is a pilot feasibility study that aims to compare a physical exercise intervention in a face-to-face context (considered state of the art) with a physical exercise intervention in a distance context (online), both supervised, in women, of legal age, physically inactive, breast cancer survivors after primary treatment with curative intent. Before and after the intervention these women will have a physical and functional assessment, as well as a pre-trial cardiopulmonary exercise test, to check if there are safety conditions to participate and also to self tailor the exercise prescription. The prescription follows the ACSM´s exercise guidelines for cancer survivors and will comprise a 8 week combined exercise training, 3 times per week, in which two of them will be supervised and the third session of the week (cardio session) won´t. Chat´s and weekly personal messages, as well as education, will be used to promote retention and exercise adherence.
This study will study circulating tumor cell (CTC) release during laparoscopic radical nephrectomy (LRN) for RCC. The main objective is to determine if CTC release can be reduced during RN by using a no-touch technique, with an early renal pedicle ligation. The investigators also aim to describe the CTC profile in terms of CTC count (CTCn), epithelial/mesenchymal status, and CTC cellular features in renal cell carcinoma (RCC) patients, stratified by "primary tumor, regional nodes, metastasis" (TNM) staging, histological subtype, and other clinical and radiological features. Patients undergoing RN will enter a two-arm prospective single-center randomized controlled trial (RCT), comparing a no-touch RN technique, with direct pedicle ligation (Group A) vs. the more conventional approach of kidney traction and manipulation to reach the renal pedicle before its ligation (Group B). A microfluidic size-based CTC isolation device will be used to capture and count CTCs from peripheral blood samples of these patients. CTCs will be identified by staining with antibodies to cytokeratin 8/18, vimentin, 4',6-diamidino-2-phenylindole (DAPI), and cluster of differentiation antigen 45 (CD45). CTC release will be correlated with the disease-free survival (DFS), and overall survival (OS). The investigators will determine if CTC reducing no-touch radical nephrectomy technique improves these hard outcomes.
After a single-tooth extraction, physiological remodeling processes are unavoidable which leads to a total loss of the periodontal ligament and resorption of the bundle bone. Immediate implant placement associated with bone substitutes and customized healing abutments seems to reduce the amount of resorption at peri-implant areas. Recently, studies evaluating the use of a connective tissue grafts are being conducted in order to assess possible final outcome advantages in immediate implant procedures. This study aims to evaluate peri-implant tissue dimensional changes after the use of a customized healing abutment with or without connective tissue graft in flapless maxillary immediate implant placement.
The objective of this survey is to investigate the current state of sepsis care around Europe. The study is aiming at hospital structure, emergency departments, wards, intensive care units and clinical diagnostic and microbiological service.
