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 dexamethasone 700 μg intravitreal implant (DEX-I) delivers dexamethasone gradually to the retina over time. It is an approved drug for the treatment of DME. This study will assess adult participants with diabetic macular edema (DME) and suboptimal response to anti-vascular endothelial growth factor therapy that are treated with DEX-I in the routine clinical setting. Approximately 327 participants who are prescribed DEX-I by their physicians will be enrolled at approximately 40 sites in approximately 10 countries globally. Participants will be followed for 18 months post-DEX-I implantation according to the routine clinical practice of the prescribing centers. Only one eye per participant will be evaluated in the study. No additional burden for participants in this trial is expected.
One of the recommended treatments for breast cancer is neoadjuvant chemotherapy (NCT), however, only 20% of the patients subject to this therapy present pathologic complete response (pCR). If exercise-induced tumour size reductions observed in preclinical studies translates to humans, physical training could emerge as a way of increasing rates of pCR to NCT, which would be a valuable clinical achievement. The present randomized controlled trial primary aim is to assess the impact of a physical exercise intervention the NCT efficacy. Following a parallel-arm design, 86 women with primary BC will be allocated 1:1 to a NCT + exercise (experimental) or NCT alone (control) group. The primary outcome is the rate of pCR in each group. Secondary outcomes include treatment tolerability and compliance, tumour infiltrating lymphocytes, ki67, immune, inflammatory, matricellular and myogenic markers, physical fitness, accelerometry, quality of life and body composition.
Study KER-012-A201 is Phase 2, double-blind, randomized, placebo-controlled study to determine the efficacy and safety of KER-012 compared to Placebo in adults with PAH (WHO Group 1 PH) on stable background PAH therapy. The study is divided into the Screening Period, Treatment Period, Extension Period, and Follow-Up Period.
Health tourism is one of the most important touristic activities. It can generate economic and social value. Balneotherapy is one of the options concerning healthcare and well-being. Although this fact it lacks information concerning effectiveness of thermal water treatments. Digital Technologies are being implemented and developed in health care systems, stimulated also by World Health Organization (WHO), in order to facilitate and improve patients' treatment and assessment. Traditional approach does not allow a follow-up due to the fact the patient leaves the thermal complex after treatment or several other reasons due to that the gap persists and social security of each country avoids support based on this lack of information. It is important to fulfil this gap and for that digital technologies seem to be the answer. This study aims to investigate effectiveness in self-management and clinical assessment and monitorization between a smartphone app (HealthSmArt_ISAVE) and a standard approach.
Lymphedema is a chronic condition causing fluid buildup in affected limbs. Traditional treatments often fall short, but subcutaneous implantation of hydrophobic silicone tubes shows promise, creating artificial drainage pathways. This approach proved effective in managing obstructive lymphedema in lower limbs. Further research is needed to validate its efficacy and explore long-term outcomes.
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 study will investigate the clinical performance of a novel restorative glass ionomer (DeltaFil, DMG) in comparison to an established restorative glass ionomer (Riva Self Cure HV, SDI) in the restoration of Class II cavities in primary molars.
The goal of this randomized clinical trial is to study the effect of an individual counseling session on the level of physical activity and motivation to practice physical exercise in individuals with COPD. The main question[s] it aims to answer are: • Does a counseling session improve the level of physical activity and motivation to practice physical exercise in individuals with COPD? Participants will perform a respiratory rehabilitation program (Control Group, CG) and a respiratory rehabilitation program and the counseling session (Experimental Group, EG). Researchers will compare EG to CG to see if there is any difference in physical activity level and motivation to exercise between groups.
