There are about 3161 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.
REALIZE was a single-arm retrospective cohort study which described treatment patterns with brolucizumab, including treatment intervals between anti-vascular endothelial growth factor (VEGF) injections before and after a switch to brolucizumab. This study was conducted using German patient-level prescription data and the prescription date was used as a proxy for anti-VEGF injection date. The study period was defined from the date of the first available anti-VEGF injection in the dataset to 30 November 2021. The index date for each patient was the date of the first brolucizumab injection, which could be anytime between 01 March 2020 (since brolucizumab became available in Germany for use outside of clinical trials in March 2020) and 30 November 2021. The date of the patient's first neovascular age-related macular degeneration (nAMD) diagnosis was assumed to be the date of the first anti-VEGF prescription in the database for that patient, from January 2015 onwards.
The general objective of this observational study is identify and describe the type, frequency, and severity of sexual dysfunction in patients with lung cancer and generate strategies for clinical management and oncological follow-up directed and based on the specific findings in this population. The recruitment will be carried out from July 2023 and will be carried out until December 2023, the analysis of the information will be carried out from January to March 2024.
This multicenter international prospective cohort study will include patients with AIS with a known or newly diagnosed anticoagulant-naïve AF. All centers will use the same transcranial Doppler machine for one-hour monitoring with bilateral 2-MHz probes within 24 hours of symptom onset. Recordings will be analyzed for MES by a blinded central reader. The primary aim is to determine the proportion of patients with MES and the association of MES with functional outcomes assessed by a modified Rankin scale (mRS) score at 90 days.
Carvedilol has emerged as the preferred non-selective β-blocker (NSBB) for treating portal hypertension. However, there is still a debate in dosing regimen, specially regarding dose interval, with a potential lower bioavalability in once daily regimens. The aim of this study is to assess the acute effects of carvedilol posology in patients with clinically significant portal hypertension (CSPH), as a surrogate marker of bioavailability. In this experimental study, patients with CSPH receiving carvedilol twice daily were asked to supress the night dose of carvedilol, in order to have a dose interval of approximately 24 hours. Spleen stiffness measurement (SSM) by transient elastography (TE) was performed and compared with SSM prior or under treatment. Same procedure was applied to liver stiffness measurement (LSM).
This study aims to assess the safety and tolerability of the individual highest tolerated zamicastat doses, achieved in the study BIA-51058-201, during long-term treatment in Pulmonary Arterial Hypertension (PAH) disease.
To assess the effect of food on the bioavailability of 3 mg cytisinicline following single-dose administration, and to evaluate the PK profile of 3 mg cytisinicline TID following multiple days of administration during Days 5-8.
Population aging in Portugal has led to problematic social issues (American Psychiatric Association, 2013; Spector, Woods & Orrell, 2008; Wimo & Prince, 2010). At the same time, there is a noticeable increase in the prevalence of Neurocognitive Disorders (NCDs), commonly referred to in clinical practice as mild cognitive impairment and dementia (Apóstolo, Cardoso, Silva & Costa, 2014; Apóstolo & Cardoso, 2014). NCDs can be classified based on the degree of cognitive decline, ranging from mild to major, and based on etiology, which includes Alzheimer's disease, Vascular dementia, Lewy body dementia, Frontotemporal dementia, and others (American Psychiatric Association, 2013). In the European context, Portugal is among the minority of countries that do not have an official strategy for the care of people with mild cognitive impairment and dementia. Therefore, it is imperative to define national health policies that address the identified needs (Knapp et al., 2006). Currently, non-pharmacological interventions, such as Individual Cognitive Stimulation (ICS), are gaining relevance as treatment responses to the aforementioned syndromes, due to the increasing clinical, social, and economic impact of mild cognitive impairment and dementia (Aguirre, Hoare, Spector, Woods, & Orrell, 2014; Apóstolo et al., 2014). ICS can be considered the implementation of a set of meaningful activities, carried out over several sessions, usually in a social context, with the aim of stimulating various domains, including attention, thinking, language, memory, and calculation (Aguirre et al., 2012; Apóstolo et al., 2014; Yates, Orrell, Spector & Orgeta, 2015). Current evidence supports the effectiveness of this intervention, indicating that ICS programs are associated with health benefits, particularly in cognition, mood, well-being, functional activity, quality of life, and communication skills (Apóstolo et al., 2014; Yates et al., 2014). Providing care to people with mild cognitive impairment and dementia poses a challenge for the healthcare system, necessitating the implementation of specific interventions to increase self-care potential, autonomy, adaptation, and coping with deficits, as well as empowering the family and/or support network (Alzheimer Europe, 2013; Orrell et al., 2012; Woods, Aguirre, Spector & Orrell, 2012; Yates et al., 2015). Due to the global pandemic context of SARS-CoV-2, social care institutions for the elderly underwent changes in their dynamics. One of the measures implemented during the emergency plan was the closure of adult day care centers. The elderly who previously attended these social care facilities are now staying in their own homes or with family/informal caregivers, thus being deprived of the social and cognitive stimuli they were accustomed to. The mobilization of this population to their homes has led to increased social isolation and loneliness, which are underestimated public health risks. These factors affect a significant proportion of the elderly population and can lead to cognitive decline, feelings of loneliness, sadness, and abandonment, which were previously alleviated by the social care centers (National Academies of Sciences, Engineering, and Medicine, 2020). Given the described situation, the Making a Difference 3 program - an ICS program - represents an excellent implementation option, as it can be developed in various contexts, including the home environment, using cost-effective resources, addressing many of the needs of both individuals with cognitive impairment and their informal family caregivers. In summary, in Portugal, there is no established practice of implementing structured ICS interventions with individual sessions for use in the home environment. Thus, there is a need for the MD3 program to be disseminated to promote best practices. In response to the needs arising from the current pandemic context, the team of this project aims to produce national evidence on the effect of ICS in individuals with mild cognitive impairment and dementia, in the home environment of the elderly person, managed by informal caregivers and supervised by healthcare professionals.
This is a observational study, that aimed to determine the prevalence of sarcopenia using European Wording Group on Sarcopenia in Older People (EWGSOP) algorithm in a general elderly population in Algarve region (Portugal). Because muscle is metabolically active tissue, sarcopenia may also contribute to the development of some of the metabolic disorders associated with aging. However, the risk factors associated with sarcopenia are poorly understood. Thus, a cross-sectional survey of a sample of 274 elderly adults aged 60 or over, were included in the study. Correlations of sarcopenia with functional level, lipid and glycemic profile, nutritional and physical activity level, fall risk, quality of life, and self-reported comorbidities will be studied.
In post-menopause, most women gain weight, and obesity rates are more prevalent in this particular group. In addition, there is an increased risk of cardiovascular disease, cancer, and diabetes. Given that this weight gain can be related to risk behaviours, healthy weight management (such as an increase in physical activity or healthy eating) is crucial to promote a healthy weight and well-being. The ME-WEL (MEnopause and WEigth Loss) project (ref. SFRH/BD/144525/2019), entails an eHealth intervention for weight management and well-being in post-menopausal women with overweight or obesity, based on two theoretical models of behavioral change - the Health Action Process Approach (HAPA), and the Health Belief Model (HBM), and applying the Behaviour Change Techniques Taxonomy (BCTT). This group's eHealth intervention lasts 8 weeks. Each week there is a different theme to be addressed, taking into account the behavioral change models mechanisms, in articulation with different BCT´s. Subjective well-being, self-esteem, weight loss, implementation of weight management strategies, and changes in eating behavior and physical activity/exercise were evaluated, through follow-ups at 3- and 6- post-intervention.
The goal of this clinical trial is to evaluate in clinically healthy young people if: - after caffeine ingestion, there are variations in blood velocity of the middle cerebral arteries (VMCA), - this variation is dependent on the administered dose. Transcranial Doppler ultrasonography was used to record blood VMCA in three groups of 15 clinically healthy young adults each - no caffeine, low caffeine (45 mg) and high caffeine group (120 mg). Transcranial Doppler ultrasonography provided simultaneous bilateral VMCA measurements while subjects performed functional tests (hyperventilation and hypoventilation orders) and three cognitive activities (Test 1, short-term remembering, Test 2, solving a vocabulary problem, and Test 3, solving a math problem) each in 31-second tests with 1-minute rest between them. Participants were assessed before and 30 minutes after caffeine ingestion.
