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.
In this randomized controlled experimental trial, it is aimed to verify the effectiveness of applying the suboccipital inhibition technique in altering forward head posture, increasing the craniovertebral angle and decreasing the angle between the chin, the external acoustic meatus and the sternal angle.
This project aims to improve direct patient care by reducing the risks of futile exposure to ionizing radiation and iodinated contrast in patients referred for coronary computed tomography angiography
Background. Chemotherapy drugs carry many side effects that may hinder the functional performance of women with breast cancer (BC). Chemoresistance can lead to treatment failure. A relative dose intensity of chemotherapy <85% is associated with a worse diagnosis and lower treatment efficacy. Exercise may modulate treatment response through its effects on the tumor microenvironment and treatment tolerability. The need for a pleasant and sustainable exercise practice is important, considering the psychological and physiological stress that accompanies women with a BC diagnosis during treatment. Studies investigating the effects of exercise interventions on chemotherapy completion rates are needed. Background.

Exercise may modulate treatment response through its effects on the tumor microenvironment and treatment tolerability. The need for a pleasant and sustainable exercise practice is important, considering the psychological and physiological stress that accompanies women with a BC diagnosis during treatment. Studies investigating the effects of exercise interventions on chemotherapy completion rates are needed. Purpose. This study will be a 2-arm pragmatic randomized controlled trial, Home-Combo, which will target Portuguese women with a breast cancer diagnosis undergoing either neo-adjuvant or adjuvant chemotherapy. The Home-Combo study primarily aims to investigate the effects of a structured, supervised, home-based combined exercise intervention with self-selected intensity, conducted across the chemotherapy treatment period, on the chemotherapy completion rates of women with BC. Secondly, this study intends to analyze the impact of this intervention on functional performance, body composition, PA levels, and quality of life. A 3-month follow-up will be performed to investigate short-term outcomes and active lifestyle sustainability post-intervention. Methods. A 2-arm randomized controlled trial will be implemented in a real-world exercise setting to compare an online structured and supervised group aerobic and strength exercise intervention with an active control group during chemotherapy treatments. The study recruitment goal is 98 women with a BC diagnosis stage I-III who are scheduled to have neoadjuvant or adjuvant chemotherapy. Outcome measures will be obtained at baseline, mid-treatment (≈3 months), post-intervention (≈6 months), and 3-month follow-up. A mediation analysis will also be conducted. Hypothesis 1: Women in the intervention will have a better completion rate than those in the control group. Hypothesis 2: Women in the intervention will present better functional performance, body composition, PA levels, and quality of life than the control group. Hypothesis 3: In the post-intervention period, women in the intervention group will maintain a more physically active lifestyle than women in the control group.
Prior research has not assessed the value of remote patient monitoring (RPM) systems for patients undergoing anticoagulation therapy after cardiac surgery. This study aims to assess whether the clinical follow-up through RPM yields comparable outcomes with the standard protocol. A crossover trial assigned participants to SOC-RPM or RPM-SOC, starting with the standard of care (SOC) for the first 6 months after surgery and using RPM for the following 6 months, or vice-versa, respectively. During RPM, patients used the Coaguchek© to accurately measure International Normalized Ratio values and a mobile text-based chatbot to report PROs and adjust the therapeutic dosage. The study assessed patients' and clinicians' experience with RPM and compared direct costs.
The SupPORT Registry aims at collecting real-world from Portuguese centers performing femoral-popliteal revascularization with Supera (r) implants. This is a prospective non-randomized non-controlled consecutive registry.
This is a prospective, open-label, single arm 3-year clinical study to describe the short-term and long-term efficacy and safety of belimumab in participants with autoantibody positive early SLE with ongoing disease activity despite stable initial SLE therapy.
This is a long-term, multicenter, non-interventional study of children ages 2.5 to <17 years with hypochondroplasia (HCH).
Peripheral arterial disease (PAD) is characterised as an atherosclerotic disease, most common in the lower limbs (aortoiliac, femoropopliteal, and infrapopliteal arterial segments), which causes a decrease in blood flow to the areas adjacent to and posterior to the affected area. Intermittent claudication (IC) is the most common symptom in this disease that appears with exertion and relieves with rest, causing fatigue, cramps, discomfort, or pain in the lower limbs due to limited blood flow to the affected muscles. Supervised physical exercise has emerged as the first line of intervention in improving the symptoms of intermittent claudication and disease progression, and in the last decade there has been an exponential increase in the use of wearable technologies to monitor dose-response. However, the approach used is still simplistic because it is not personalised. In other words, patients with similar diagnoses and symptoms get the same treatment, without personalising the stimulus according to their exercise responses and level of adaptation. With this in mind, this study aims to monitoring the real-time response of a multicomponent exercise programme (cardiovascular and resistance training) to personalise the dose-response, and use artificial intelligence models to gather and analyse vast amounts of data towards grouping/differentiating based on individual responses. The main hypothesis is that a supervised multicomponent exercise programme will improve the functional capacity of patients with PAD in a cluster personalised approach.
PURPOSE: The purpose of the study is to determine the effects of 16-weeks of exercise training, as measured by aerobic capacity, strength and physical function, and body composition, in patients with Chronic Lymphocytic Leukemia (CLL). DESIGN: Subjects will have confirmed treatment naïve CLL. Subjects will be assigned to either a 16-week control group (no supervised exercise) or an intervention group of Resistance Training (REx). Before and after the 16-week protocol, patients will undergo several tests including: 1) a maximal cycle ergometer test, 2) Body Composition, 3) Muscle strength, 4) physical activity levels, 5) blood measures (e.g. immune and inflammatory functions). DATA ANALYSES & SAFETY ISSUES: For outcomes, group change differences from baseline to 16-weeks will be compared with ANCOVA. Resistance training is a very safe exercise modality already studied in other cancer patients. The regular use of vigorous-intensity exercise has been used extensively in exercise training. It will always be respected for each subject's safety tolerance while challenging. HYPOTHESIS: The investigators hypothesize that the protocol will be feasible exercise interventions for people with CLL and will improve health and fitness markers.
The primary goal of this study is to assess in vivo the efficacy of the insoles, in improving venous return in subjects affected by this problem after 14 days of the initial measurements, by self-assessment, filling-in questions regarding Quality of Life, in comparison with a control group. The secondary goal of this study is to assess in vivo the acceptability of the subjects regarding the same medical device, after 14 days of using the medical device, by selfassessment, filling-in subjective evaluation questions.
