There are about 21071 clinical studies being (or have been) conducted in Spain. 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.
Normal-pressure hydrocephalus is associated with increases in the intracranial pressure during the night sleep. Sleep apnea also increases the intracranial pressure during the apneic spells. When patients are operated the distal part of the shunt is inserted inside the abdominal cavity, which pressure also increases during the sleep apnea episodes. this is particularly important considering that the recumbent position used to sleep further increases the intraabdominal pressure and that impairs the CSF drainage through the shunt system. The purpose of this study is to analyze the intracranial and intraabdominal pressures during the sleep, particularly during the sleep apnea episodes to see which shunt should be used, to which cavity should be drained (peritoneum or heart) and if correcting the sleep apnea has some positive result on the hydrocephalus symptoms.
The aim of this project is to evaluate the effects of positional changes in mechanically ventilated patients.
The primary purpose of this study is to determine whether treatment with lecanemab is superior to placebo on change from baseline of the Preclinical Alzheimer Cognitive Composite 5 (PACC5) at 216 weeks of treatment (A45 Trial) and to determine whether treatment with lecanemab is superior to placebo in reducing brain amyloid accumulation as measured by amyloid positron emission tomography (PET) at 216 weeks of treatment (A3 Trial). This study will also evaluate the long-term safety and tolerability of lecanemab in participants enrolled in the Extension Phase.
There are two main goals of this study: The first is to find the highest safe dose of REGN6569 when given with cemiplimab. The second is to get some initial information about how well the REGN6569 in combination with cemiplimab may help shrink certain types of cancer. The study is also looking at: - Side effects that may be experienced by people taking REGN6569 alone and with cemiplimab - How REGN6569 and cemiplimab work in the body - How much REGN6569 and cemiplimab is in your blood - To see if REGN6569 can lower the number of Treg cells in tumors - To see if REGN6569 and cemiplimab can shrink tumors when given together
The objectives of this proposal are to: 1) determine the rate of SARS-CoV-2 seroconversion in unselected pregnant women in Hong Kong; 2) determine the rate of SARS-CoV-2 infection in women presenting with miscarriage and stillbirth; 3) follow the pregnancy course and perinatal outcome of confirmed COVID-19-infected pregnant cases; 4) determine the risk and characteristics of vertical transmission; and 5) evaluate the placental barrier, immune response and fetal damage in vertical transmission of SARS-CoV-2. A series of longitudinal and cross-sectional observational studies, and a laboratory-based study will be conducted to fulfil the 5 objectives.
The study will be a multicentric, prospective open-label ethics committee approved clinical study to investigate safety, visual outcomes, contrast sensitivity and rotational stability after bilateral implantation of Isatis TF IOL following cataract surgery.
In this prospective, unicentric, case-control study, the main aim is to analyze joint movement and walking patterns in patients with acute stroke with a marker-free motion capture system. Case group: Stroke patients who fulfill the inclusion criteria are invited to participate in the study during admission. The evaluation consists of a workout designed by expert rehabilitation physicians and neurologists that is performed by the patient in front of the Microsoft Kinect camera. The custom-built software Akira record the joint angles of body trunk and upper limbs during the workout. The kinematic data will be analyzed with a machine learning algorithm that classifies the participant according to the kinematic data in normal movement or impaired movement (with the degree of impairment) by age decade. Control group: healthy participants (without neurological or osteomuscular diseases) matched by age and sex with cases 1:1. The correlation between kinematic and clinical scales (NIHSS) and functional scales (modified Rankin Scale) will be analyzed. A secondary objective will be to analyze the predictive value of the kinematic measurements with the functional outcome at three months
In hypertension, highly prevalent, up to 10-15% of hypertensive patients have uncontrolled blood pressure despite being treated with ≥3 drugs, which is known as resistant hypertension. Resistant arterial hypertension, together with difficult-to-control hypertension, has a worse cardiovascular prognosis than controlled hypertension. In addition, data on therapeutic adherence in arterial hypertension show that 1 in 2 hypertensive patients do not fully or partially comply with the indicated therapeutic prescription. The determination of antihypertensive drugs or their metabolites in urine seems to be a good indicator of therapeutic adherence. On the other hand, the implementation of a specific program to improve knowledge of the disease and its risks and promote therapeutic adherence could improve the control of hypertension and reduce the associated morbidity and mortality.
The primary objective of the study is to evaluate the effectiveness of fremanezumab as compared to placebo for the preventive treatment of chronic migraine (CM). Secondary objectives are to further demonstrate the efficacy of Fremanezumab as compared to placebo for the preventive treatment of CM, to evaluate the safety and tolerability of Fremanezumab in the preventive treatment of CM and to evaluate the immunogenicity of Fremanezumab and the impact of antidrug antibodies (ADAs) on clinical outcomes in participants exposed to Fremanezumab The total duration of the study is planned to be 75 months.
This study will be conducted to evaluate the efficacy, safety, and tolerability of AVP-786 (deudextromethorphan hydrobromide [d6-DM]/quinidine sulfate [Q]) compared to placebo for the treatment of agitation in participants with dementia of the Alzheimer's type.
