There are about 36633 clinical studies being (or have been) conducted in France. 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.
Parkinson's disease is the second most common neurodegenerative disease in the world. One of these manifestations is the freezing of gait (FOG) which affects 50 to 80% of Parkinsonian patients. It is defined as a brief and episodic absence or marked reduction in the forward progression of the feet despite the intention to walk. FOG is one of the most disabling symptoms causing a greater risk of falling and a loss of autonomy for these patients. This symptom is little or not dopamine-sensitive and little improved by surgery (deep brain stimulation). Although this symptom is common and debilitating, it is difficult to assess clinically. The objective assessment of the presence and severity of FOG episodes can be done with tests such as the New-Freezing of Gait Questionnaire (N-FOGQ) with however limitations. Indeed, this filmed examination is scored a posteriori and the accumulation of the administration times which makes it difficult to use in routine clinical practice. To overcome these limitations, the use of a diary completed by the patient himself is a simple alternative to assess this symptom, but studies show that patients abandon this practice in the long term and that it is not used by patients with cognitive impairment. Recent advances in miniaturization have made it possible to create light and compact sensors to assess these events objectively. Inertial measurement units have been widely used in the literature to detect FOG episodes. The choice of the detection algorithms are a major issue in the scientific community. To date, due to the heterogeneity of the protocols, no method is currently required as a reference. The objective is to evaluate the accuracy of a new algorithm to detect the number of FOG episodes in Parkinsonian patients. This evaluation will be done on the freeze-inducing walking path.
Allergy to nuts (cashew, pistachio, walnut, exotic nuts) is a frequent allergy in children, with a prevalence of up to 4.9% of the population and a low resolution rate (9%). Among the nut allergies, cashew nut allergy is one of the most frequent in Northern Europe: in France 41% of children allergic to nuts are sensitized to cashew nuts. Moreover, cashew nut allergy is associated with severe reactions that can be lethal in both adults and children. These reactions may even be more severe than those observed with peanuts, with more frequent respiratory and cardiovascular impairment. We note reactions for even limited contacts (cutaneous or mucous) and low reactogenic thresholds. However, the only recommendation for management at present is avoidance. The stakes of oral immunotherapy protocols cashew would be similar to those for peanut immunotherapy: to limit reactions in case of accidental intake, increase the reactogenic threshold and thus improve the quality of life of allergic patients. To date, only one study has focused on the efficacy and tolerance of cashew immunotherapy : the prospective NUT CRACKER study conducted on 50 children aged 4 years or older with cashew nut allergy between 2016 and 2019, reports a good efficacy of immunotherapy on increasing threshold for cashew nut but also for pistachio and walnut, when there was a cross-over allergy. While the tolerance was similar to other immunotherapy protocols for the other foods. The objectives of part 2 of the CAJESITO study are (i) to evaluate the tolerance of oral cashew nut immunotherapy, by describing the frequency and severity of allergic reactions during oral cashew immunotherapy and (ii) to identify risk factors for severe risk factors for severe allergic reactions during oral cashew immunotherapy.
The study evaluates the efficacy of an adapted antibiotherapy in Hurley stage 2 active Hidradenitis Suppurativa patients versus tetracycline derivative
Developmental care are recognized as a standard of care for preterm infants in neonatal intensive care units. Regular skin-to skin contacts during the neonatal stay show short and long-term beneficial effects on preterm infants and their parents. Skin-to-skin contact provides hemodynamic and thermal stability in preterm infants. Regarding parents, skin-to-skin contact sustains the parental bonding, and reduces stress and anxiety related to hospitalization. As a result, early skin-to-skin contact has been associated with an improvement of neurological outcome in very preterm infants. Thermal stability is crucial during the first hour of life in preterm infants. A temperature at admission in the neonatal intensive care unit below 36.5°C or above 37.2°C has been associated with an increase in neonatal morbidity and mortality. Early skin-to-skin contact between a newborn and his/her mother in the delivery room significantly decreases the occurrence of hypothermia below 35.5°C. The practice of skin-to-skin transfer from the delivery room is emerging in France. Pilot studies have been carried out by French neonatal teams that showed the feasibility of this practice in late-preterm, near-term and term infants. Although skin-to-skin contact routinely involves very preterm infants in neonatal intensive care units worldwide, the feasibility and safety of skin-to-skin contact during the transfer from delivery room to the neonatal unit is poorly documented in very preterm infants. Previous data of our team showed that transfer of preterm infants with non-invasive ventilation using skin-to-skin contact was feasible and safe but concerns emerged about the thermal conservation during the procedure. The main hypothesis of this study is that skin-to skin contact during the transfer from the delivery room to the neonatal intensive care unit could prevent heat losses in preterm infants as well as the transfer in incubator. Another hypothesis is that very early skin-to-skin contact could positively influence the neonatal course and the parental experience in the neonatal care unit.
In the 2016's Haute Autorité de Santé (HAS) recommendations (Haute Autorité de Santé. Management of arterial hypertension in adults. Saint-Denis La Plaine: HAS; 2016.) concerning the management of arterial hypertension in adults, the Ambulatory Blood Pressure Measurement (ABPM) is described as a diagnostic tool for hypertension as well as a tool useful for checking blood pressure (BP) control in treated patients. It is also stipulated that ABPM can provide additional information such as the exploration of significant blood pressure variability. The 2014's ESH recommendations (ESH practical guidelines for ambulatory blood pressure monitoring, 2014) concerning ABPM indicate that variability of BP over 24 hours can be considered as a research parameter. Blood Pressure Variability could be a better predictor of organ damage related to hypertension than blood pressure measured in consultation. Furthermore, BP measurement over 24 hours has been demonstrated as a more sensitive risk factor for cardiovascular events such as stroke or ischemic coronary events. It is specified in the 2018 ESH/ESC guidelines on the management of hypertension (Mancia G, et al. 2018 ESC/ESH Guidelines for the management of arterial hypertension. 2018) that an additional number of ABPM parameters may have prognostic value such as 24-hour variability even if there is no indication yet of its evaluation in clinical routine. The variability of blood pressure is associated with an increased risk of cardiovascular events, in particular stroke and coronary events in young and hypertensive patients, regardless of their cardiovascular risk factors, mean value of their systolic BP measured in ABPM or during consultation follow-up as shown by Rothwell PM et al. (Prognostic significance of visit-to-visit variability, maximum systolic blood pressure, and episodic hypertension. The Lancet. mars 2010;375(9718):895-905) and Mehlum MH et al. (Blood pressure variability and risk of cardiovascular events and death in patients with hypertension and different baseline risks. Eur Heart J. 21 juin 2018;39(24):2243-51.) Studies also show that BP variability in elderly hypertensive patients is an independent risk factor for cardiovascular events (Eto M et al. Impact of Blood Pressure Variability on Cardiovascular Events in Elderly Patients with Hypertension. Hypertens Res. 2005;28(1):1-7.) and that BP variability would be greater in the elderly patient (Magdás A et al. Ambulatory monitoring derived blood pressure variability and cardiovascular risk factors in elderly hypertensive patients. Biomed Mater Eng. 2014;24(6):2563-9) Finally, a link between frailty and blood pressure variability is demonstrated by Rouch L et al. (Visit-to-Visit Blood Pressure Variability and Incident Frailty in Older Adults. Le Couteur D, éditeur. J Gerontol Ser A. 13 juill 2021;76(8):1369-75.) However, BP variability, measured in this study by blood pressure variation between clinical visits, does not assess overnight variability. Another limitation in the evaluation of frailty is the exclusion of patients with an MMSE < 24. Hussain SM et al. (Variation in Mean Arterial Pressure Increases Falls Risk in Elderly Physically Frail and Prefrail Individuals Treated With Antihypertensive Medication. Hypertension. sept 2022;79(9):2051-61.) also show that BP variability measured by ABPM would increase the risk of serious falls in frail or pre-frail elderly subjects taking antihypertensive treatment. The objective of this study is therefore to evaluate the link between blood pressure variability on 24-hour recordings measured by the standard deviation and the coefficient of variation, according to the frailty status in patients aged over 75 with hypertension, treated or not with antihypertensive molecules.
This study aims to compare two screening strategies for identifying infants with a potential risk of Autism Spectrum and Neurodevelopmental Disorders to provide early access to care and increase the likelihood of a favorable outcome
Elderly adults have high rates of emergency department (ED) visits. Specificities of this population challenge organizations of care in the ED, and older adults are at risk of pejorative outcomes after an ED stay. Numerous interventions have been designed to improve quality of care and outcomes for the older population in these settings, with a specific attention to concerning discharge from the ED. These interventions are interdisciplinary, bridging emergency and geriatric care. The wide range and complexity of these interventions make them difficult to assess and compare, as highlighted by several reviews in the past ten years. Prior analyses helped to categorize different intervention strategies and three main designs: inhospital, community and transitional interventions started in the ED and pursued in collaboration with community primary care professionals . Theses analyses show that the use of multiple strategies and transitional models of care tend to lead to better outcomes, and underline that more robust studies are needed to confirm this hypothesis. In France a majority of EDs collaborate with Geriatric Mobile Teams (GMT) to improve quality of care for older patients. GMTs are dedicated to patients over 75 years old, and interventions in EDs are targeted on patients at risk of worse outcome. When ED physicians detect older patients at risk they may call for the GMT for further assessment and management. GMTs either work in a inhospital standard approach or with a transitional care management. This second strategy, less common in France, is thought to be be efficient and has never been assessed. We have designed a study to compare these methods, with the hypothesis that among at-risk older adults, hospital-community transition care initiated by GMTs during an ED visit with direct discharge home will be associated with a reduction in the risk of early readmission within 30 days, and lower risk of loss of independence at 3 and 6 months. It is a french multicentric study, with a quasi-experimental design, comparing hospitals without transitional care management to hospitals with hospital-community transitional intervention. We aim at enrolling 1322 patients aged 75 and more at risk of pejorative outcomes as determined by the Triage Risk Screening Toll (TRST). The main outcome is a revisit to the ED between day 7 and day 30, secondary outcomes are autonomy, mortality, use of hospital services and caregiving at home at 6 months.
Newborn's renal function is difficult to assess and its physiology during the first days of life is still incompletely known. Studies suggest that the newborn almost completely reabsorbs creatinine during the first 48 to 72 hours of life, while at the same time it continues to produce its own creatinine. Therefore, the initial stock of creatinine at birth still increases through this production and the non or weak clearance. A better knowledge of renal physiopathology in newborns would allow to improve the therapeutic management of the infants, particularly in case of potential nephrotoxicity. No study has attempted to assess the increase in urinary creatinine excretion in neonates from a given time. Objectives: To show when urinary creatinine excretion in newborns is efficient. Results: this study mightr show an inflection point in urinary creatinine excretion illustrating the postnatal age when renal function becomes efficient.
Parkinson's disease is the second most common neurodegenerative disease after Alzheimer's disease. It is mostly characterized by the presence of motor difficulties. However, it can also be accompanied by cognitive disorders which have an equally significant impact on the quality of life of patients and which are not relieved by any treatment. Among the functions affected by Parkinson's disease, inhibition is an essential process for adapting our behaviors in daily life. Inhibition allows us to stop an action that is no longer required or appropriate to the situation in which we find ourselves in. For example, it comes into play when we have to stop at a "stop" sign while driving. Recent studies suggest that it could be possible to improve the functioning of these processes by using non-invasive brain stimulation tools. Transcranial alternating current electrical stimulation has thus showed promising results in improving functions such as working memory. This technique is completely painless and non-invasive and consists in applying an electric current of very low intensity (barely perceptible) at the level of the scalp, using electrodes. The investigators are conducting a study to test whether transcranial alternating current electrical stimulation could improve the functioning of the inhibition process which is altered in patients. For this, the investigators will measure this process using a task performed on a computer (the Stop Signal Reaction Time Task), as well as brain activity using a method called "electroencephalography", before and after stimulation. For this study, the investigators will include 50 patients and 40 healthy participants to investigate the effect of the stimulation on inhibition.
Rheumatoid arthritis (RA) is a disabling disease leading to joint and bones destruction. This autoimmune disease is multifactorial, and some genetic and environmental risk factors are already described. However, a part of heritability is still unknown. Previous genomics studies dedicated to deciphering this missing heritability did not pay attention to age of onset. The purpose of this protocol is to determine genomic markers which are specific of RA with an age of onset above 65 years old. Indeed, clinical presentation, treatment tolerance and efficiency, and frequent comorbidities of this phenotype are particular. This signature of genomic biomarkers will be integrated in known molecular pathways to highlight specificities, helpful for biological targets identification.
