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.
Phase II, randomized, Active-controlled open label trial for treatment of high risk, HR-/HER2- (triple negative) breast cancer, with two sequences of neoadjuvant chemotherapy on a background of pembrolizumab
Ingestion during labor is an issue that has attracted the attention of the scientific community in recent decades, with different practices occurring in different countries. However, the scientific evidence of the risk / benefit of fluid intake in labor is still not fully understood. The aim of this study was to contribute with data that allow the evaluation of an eventual relationship between the amount of fluid ingested during labor and the type of delivery, the duration of labor, the occurrence of nausea and vomiting and the value of the Index of Apgar at the 1st and 5th minutes of the newborn's life. An observational study, with a convenience sample of 144 parturient from two hospitals of Portugal were employed. The analysis was based on recording the before mentioned variables and potentially confounding variables. In order to control for potential sources of bias in the study and to guarantee the homogeneity of the sample in the specific statistical treatment of each dependent variable, an observation grid was drawn up for all the participants in the study. Twenty eight of the parturient, the parturient's ambulation, labour analgesia, food intake during labour, the use of oxytocin during labour, the occurrence of postpartum complications, the birth weight of the newborn and the occurrence of birth complications.
This study aims to test the effectiveness and cost-effectiveness of two different strategies of home-delivered HPV self-sampling, in comparison to the standard of care strategy, to increase adherence to cervical cancer screening. An experimental and population-based study will be implemented at three primary healthcare centers located in the Western Porto region: Cedofeita, Garcia de Orta, and Prelada. Eligible women will be randomized into a control group or an intervention group. The control group will correspond to the standard of care (invitation to screening in a clinical setting). The intervention group will be randomized into two subgroups: 1) a "directly mailed" group that will receive a self-sampling kit at their home addresses by post; 2) an "opt-in" group that will receive an invitation at home asking if they want to receive a self-sampling kit, with a pre-paid envelope to return the answer to this question. Women who answer "yes" will receive the self-sampling kit at their home addresses by post. Self-sampling samples will be subjected to HPV genotyping. In parallel, high-risk HPV positive women will be called in by their family doctors to undergo screening in a clinical setting so that they can continue their clinical follow-up in the conventional pathway.
A Post-Market Clinical Follow-Up (PMCF) Study to collect clinical data on safety and performance of all TEKNIMED Spine range of products: SPINEFIX, HIGH V+, OPACITY+ and F20 bone cements and mixing and injection systems, and all their private labels. TEKNIMED bone cements are legacy products, some marketed for more than 10 years. Their performance and safety have already been demonstrated by Post-Market Surveillance and previous clinical studies. The current Post-Market Clinical Follow-Up study aims to confirm these claims by collecting data in a "real-life" setting. The study is a retrospective and prospective global, single arm, non-controlled, multicentric, prospective observational study. Patients will be followed as per local standard medical care of the sites.
Emerging evidence suggests that following a 'carbohydrate-last meal pattern', wherein foods rich in protein, fat, fiber, and/or polyphenols are consumed before sources of simple carbohydrate (CHO) in a meal, results in reduced postprandial glycaemic responses than the reverse food order or a co-ingestion pattern. This effect has been observed across the spectrum of glucose tolerance, from patients with diabetes to individuals with normal glucose tolerance (Kuwata et al., 2016; Nishino et al., 2018; Lu et al., 2019; Sun et al., 2020). Furthermore, reduced glucose excursions have been linked to decreased subsequent hunger and energy intake (Lu et al., 2019; Wyatt et al., 2021). However, to date, no studies on food intake sequence have targeted athletes, despite their increased CHO demands (Thomas et al., 2016) which could expose them to repeated episodes of hyperglycaemia and high glycaemic variability, known to increase the risk of adverse cardiovascular outcomes and all-cause mortality (Loader et al., 2015; Cavero-Redondo et al., 2017; Faerch et al., 2018). Additionally, athletes often face pressure to meet body composition standards and may benefit from strategies that enhance satiety and craving control. Finally, there is reason to believe that better glycaemic control could lead to improved performance, given that enhancements in endurance activities have been observed with a low-glycemic-index diet compared to a high-glycemic-index diet (Heung-Sang Wong et al., 2017). Therefore, this randomised crossover trial is part of a wider project which seeks to explore the impact of food intake sequence on metabolic health and performance in athletes. Specifically, this trial aims to investigate the acute, postprandial metabolic and appetite responses to consuming an identical meal in two intake sequences (CHO-last versus CHO-first) in athletes, while in the resting state.
It is known that there are studies that prove the effectiveness of muscle energy techniques and the fourth ventricle technique separately, however, information is scarce regarding the combination of the two and their effectiveness in the population. The aim of this randomized controlled study is to compare the immediate effects of the techniques compared to the muscle energy technique alone in female basketball players.
The purpose of this study is to compare the effectiveness and safety of golcadomide in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy vs placebo in combination with R-CHOP chemotherapy in participants with previously untreated high-risk large B-cell lymphoma (LBCL).
Study: observational prospective clinical study. Study population: Subjects over 55 years old with drusen secondary to intermediate AMD. Recruitment: at the Medical Retinal Consultation from the Ophthalmology Department of CHULC. Primary outcome: Identifying imaging predictors of iAMD progression.
The goal of this interventional clinical trial is to assess the safety, usability and initial efficacy of Xeomin and Vibe combination (ViXe) compared to placebo + sham in female subjects with idiopathic Overactive Bladder. The main question[s] it aims to answer are: • The rate of device and drug related serious adverse events during treatment and throughout the follow up period • Investigator, subject and technician satisfaction from treatment, and • Assess the initial efficacy of the drug-device combination compared to placebo-sham combination. Participants will be treated a single time with the ViXe combination and will be followed up for a period of 12 weeks, during which they will visit the clinic after 2, 6 and 12 weeks. Participants will complete a 3-day voiding diary prior to the 6- and 12-week FU visit.
The aim of this study was to investigate the effects of different concentric and eccentric muscle fatigue protocols on the knee joint position sense of healthy individuals.
