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.
This study will assess the predictive potential of circulating placental biomarkers for spontaneous miscarriage within the following month in an IVF setting. It is hypothesized that a robust algorithm including one or more of these biomarkers may allow for the accurate same-day distinction between women with a low and high risk of a spontaneous miscarriage.
PURPOSE: To evaluate the effect of the vitreous in response to intravitreal (IV) injections of ranibizumab 0.5 mg/0.05ml (Lucentis; Genentech, South San Francisco, CA) for the treatment of diabetic macular edema (DME). METHODS: Prospective, observational, multicenter study, conducted at Centro Hospitalar e Universitário do Porto, Portugal. Best-corrected visual acuity and central foveal thickness will be evaluated at baseline and every month until the end of follow-up. OCT biomarkers such as retinal layers thickness will also be analyzed. A p value of 0.05 or less will be considered to be statistically significant. HYPOTHESIS: Vitrectomized patients will improve less than non-vitrectomized patients.
The aim of this study is to explore the effect of a low starch diet (reduction of at least 40%) in the gut bacteria modulation, especially Klebsiella pneumoniae, and its relation to disease activity, functional impairment and quality of life in patients with Ankylosing Spondylitis (AS).
Colonoscopy is currently accepted as the gold standard in screening, surveillance and prevention for colorectal cancer (CRC), and therefore, its quality is a major priority. The quality of colonoscopy is greatly dependent on the quality of the bowel preparation, which can be limited by stool, foam, bubbles and other debris. In fact, colonic bubbles are described in 30 to 40% of colonoscopies, possibly undermining the quality of the exam, impairing the endoscopists view, demanding the further use of water or simethicone and eventually increasing fatigue and costs, while diminishing diagnostic accuracy. Although previous attempts, to date no endoscopic scale is validated regarding the presence of bubbles and most widely accepted and already validated scales do not include the presence or absence of bubbles in their definition, leading to the use of different home-made scales in randomized trials and impairing any solid meta-analysis conclusion. As so, the goal of this study is to develop and validate a new colonic bubble score (Colon Endoscopic Bubble Scale - CEBuS).
The frailty syndrome (FS) is characterized by a multifactorial clinical syndrome, which includes 5 items, 1 - Change in body composition, 2 - Holding force, 3 - Fatigue reported, 4 - Reduction of walking speed, 5 - Low physical activity. The cumulative effect of deficits on the physiological functions caused by the syndrome results in early physical and cognitive loss. It is known that physical exercise, associated with protein supplementation are examples of non-pharmacological treatments that can promote functional and structural adaptive responses of the skeletal muscle system. One of the factors related to frailty is the reduction of body and muscle mass. Branched-chain amino acids, especially leucine, are nutrients that influence the adaptative response of muscle. It is intended through a physical exercise program (multicomponent = exercise of strength + aerobic exercise), to attenuate the effects of ageing and mainly of physical and cognitive frailty, evaluating the health parameters of frail elderly, alone or together with supplementation (BCAA), branched-chain amino acids, modulation of immune markers, markers of malnutrition and the skeletal muscle system in frail and pre-frail dwelling elderly people living in the city of Coimbra. To achieve that, the following parameters will be evaluated: biosocial indicators, anthropometric evaluation and body composition, indicators of global health and functional physical fitness, inflammatory biomarkers, neuroendocrine, signs of skeletal muscle function, evaluation of quality of life related to emotional state, cognitive profile and frailty-trait evaluation. The results obtained from the indicators, markers and questionnaires used are expected to contribute to the attenuation of frailty, improving the health and quality of life of the elderly. Keywords: frail elderly, multicomponent exercise, branched chain amino acid, healthy life
With the main goal of generalising findings into Virtual Reality-Neurofeedback-Motor imagery (VR-NF-MI) system, this project aims to develop a new motor rehabilitation tool, for the upper limb, allied to the use of rising of information and communication technologies (ICT). By identifying correlations on the neural activity, during motor imagery and through brain imaging (fMRI), with distinct training protocols and feedback, these protocols are developed to create user-specific models that later can be used in NF-MI rehabilitation sessions.
This is an open-label, multicenter, rollover study to evaluate the safety, tolerability, and efficacy of long-term administration of open-label gantenerumab in participants with AD who completed Study WN29922 or WN39658, either the double-blind or open-label extension (OLE) part.
A phase 3 double blind, placebo controlled study evaluating the efficacy and safety of AL001 in participants at risk for or with frontotemporal dementia due to heterozygous mutations in the progranulin gene.
Vitamin D deficiency has been linked to hypertension, autoimmune, infectious and cardiovascular diseases which are risk factors for COVID-19. Moreover, COVID-19 patients have a very high prevalence of hypovitaminosis D (Turin data). Taken together, we aim to investigate whether genetic variants in vitamin D-related genes contribute to a poor COVID-19 outcome, particularly in hypertension and CV patients, proposing thus a personalized therapeutics based on vitamin D supplementation in order to reduce the severity and deaths.
This study aims at investigating handwashing behavior during COVID-19 pandemic. It was hypothesized that social-cognitive and emotional predictors as well as COVID-19 morbidity and mortality rates within the country would be associated with handwashing behavior in the general population of adults in 14 countries.
