There are about 13332 clinical studies being (or have been) conducted in Netherlands. 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.
Malaria is one of the major infectious diseases in the world with a tremendous impact on the quality of life, significantly contributing to the ongoing poverty in endemic countries. It causes 800.000 deaths per year, the majority of which are children under the age of five. The malaria parasite enters the human body through the skin, by the bite of an infected mosquito. Subsequently, it invades the liver and develops and multiplies inside the hepatocytes. After a week, the hepatocytes burst open and the parasites are released in the blood stream, causing the clinical phase of the disease. As a unique opportunity to study malaria immunology and efficacy of immunisation strategies, a protocol has been developed in the past to conduct controlled human malaria infections (CHMIs). CHMIs generally involve small groups of malaria-naïve volunteers infected via the bites of P. falciparum infected laboratory-reared Anopheline mosquitoes. Although potentially serious or even lethal, P. falciparum malaria can be radically cured at the earliest stages of blood infection when risks of complications are virtually absent. The investigators have shown previously that healthy human volunteers can be protected from a malaria mosquito (sporozoite) challenge by immunization with sporozoites (by mosquito bites) under chloroquine prophylaxis (CPS immunization). Interestingly, sterile protection in 100% of the human CPS immunized volunteers was achieved by a relatively miniscule dose, i.e. a total of 45 infectious mosquito bites, strikingly 20-fold more potent than the 1000 bites needed in a model using irradiated mosquitoes. One possible explanation for this efficient induction of protective immunity, is the immune modulating effect of chloroquine. The investigators aim to assess this possible immune modulating effect in CPS immunization by comparing immunization with P. falciparum sporozoites under chloroquine with immunization under mefloquine prophylaxis, which has the same antimalarial effect, but not the immune modulating effects known from chloroquine.
Ageing is related to a decrease in physical fitness, disability and age related symptoms like nocturnal leg cramps (NLC). Our research is focused on the enhancement of physical activity and mobility to increase physical fitness and decrease disability and nocturnal cramp in older adults.
The purpose of the present study is to investigate whether or not to perform elective surgical repair of umbilical hernias in patients with liver cirrhosis and ascites. There are no other randomized controlled trials in this area. The optimal management in patients with umbilical hernias and liver cirrhosis with ascites is not clear yet. The general surgical opinion is that umbilical hernias in patients with ascites should not be corrected because of the supposedly high operative risks and high recurrence rates. Conservative treatment, however, can have severe complications resulting in emergency repair. Such operations carry a higher risk of complications than elective operations, particularly in this group of patients. Prospective and retrospective series showed us that elective hernia repair in this specific patient group is safe without major complications or high recurrence rates. The aim of this study is to asses the optimal timing of correction of umbilical hernia in patients with liver cirrhosis and ascites.
The PneumRx Lung Volume Reduction Coil (LVRC) has been shown to effectively improve quality of life, exercise capacity, and static lung volumes, in patients with emphysema. The mechanism of action for these effects is believed to be related to the restoration of elastic recoil to lung parenchyma that has been damaged by emphysema. The objective of this study is to evaluate several physiologic parameters which should provide measures directly related to the mechanism of action by which the coils produce these outcomes.
This is a 8-year extension study in pediatric subjects who have been diagnosed with one of 3 subtypes of Juvenile Idiopathic Arthritis (JIA) [extended oligoarticular JIA, enthestitis related arthritis (ERA), or psoriatic arthritis (PsA)] who have completed approximately 96 weeks of participation in study 0881A1-3338 (B1801014). The study contains an active treatment period, withdrawal/re-treatment period and a observational period (non-treatment).
The purpose of this study is to demonstrate comparability of the ORR in patients with previously untreated, advanced stage FL who receive GP2013-treatment to patients who receive MabThera-treatment.
The purpose of this study is to evaluate the safety and effectiveness of the OMEGA Coronary Stent System for the treatment of subjects with a de novo atherosclerotic coronary artery lesion.
Studies on resting human muscle show that ingestion of the branched-chain amino acids (BCAA): leucine, valine and isoleucine have an anabolic effect on muscle protein metabolism. However, the effects of BCAA intake on protein metabolism during exercise are less clear. When BCAA were supplied as single amino acids, without other amino acids and/or carbohydrates, no effects were observed on protein kinetics. On the other hand, ingestion of BCAA during running appeared to reduce the catabolic effect of running on muscle protein metabolism. These experiments were all performed with mixtures of the BCAA with or without carbohydrates but not in the form of complete meals with food protein as a basis. Therefore, it is still unknown whether a protein meal, containing a substantial amount of BCAA is beneficial during exercise by inducing an anabolic effect. Whey and Casein protein contain a substantial amount of BCAA in contrast to Soy protein. Therefore, it is hypothesized that milk-based proteins are a better and more physiological source of BCAA during exercise and will lead to more protein anabolism. Most of the available studies have been carried out in young and fit humans but there are hardly any data are available in the increasing population of the elderly. Therefore it is still unknown whether a BCAA rich protein meal can enhance the anabolic effect of exercise in older individuals. Besides sarcopenia, a substantial part of the elderly is suffering from a chronic systemic disease such as chronic obstructive pulmonary disease (COPD). COPD represents an important health care problem. COPD is the fourth leading cause of death and will be the third leading cause worldwide in 2020. Besides the local impairment, COPD is a chronic wasting disease, associated with alterations in intermediary metabolism. Substantial disturbances have been found in BCAA (and related) metabolism in these patients at rest and during exercise. It might therefore be of clinical relevance to study the metabolic effects of BCAA rich protein meals in patients with COPD at rest and during exercise.
Healthy but sedentary aging leads to increased morbidity and mortality of cardiovascular disease. This is partly due to the accumulation of Advanced Glycation Endproducts (AGEs) and the stiffening of the myocardium and arteries. New medication has been developed to break these AGE-crosslinks to improve cardiovascular compliance. The positive influence of regular physical activity is well known for cardiovascular disease and aging. Therefore, what is the most effective intervention, physical exercise and/or new medication AGE-crosslink breakers, in improving the cardiovascular and cerebrovascular compliance and improving the endothelial function in healthy sedentary elderly.
SRT2379 is a potent small molecule activator of SIRT1 that has been found to inhibit systemic inflammation induced by intravenous injection of lipopolysaccharide (LPS) in mice. The objective of this study is to determine the effect of a single administration of SRT2379, at multiple-dose levels, on the inflammatory response to low dose endotoxin.
