title: Medico-economic Evaluation of Strategies for the Lead Extraction of Implantable Defibrillator and Pacemakers: a Retrospective Observational Study

acronym: GAINE LASER

summary:
The growing use and the expanding indications for cardiovascular implantable electronic devices (CIEDs) have been associated to an increase of device removal. The indications of CIEDs removal are infectious (55%) or noninfectious (45%) such as upgrading of devices, nonfunctional devices and thrombosis. Removal can be performed according to transvenous or surgical procedures. Transvenous lead removal (TLR) must be done by experimented cardiologists and respecting current consensus. TLR can be done with conventional techniques involving inserting locking stylets and telescoping sheaths around the pacing leads to separate them from the surrounding scar tissue. These conventional procedures have a success rate of ≈65%. TLR thanks to laser sheath has been validated and improved the success rate until >95%. However, the TLR from chronically implanted CIEDs still carries a significant risk of procedural failure, morbidity, and mortality, related to tearing of the great vessels and cardiac structures, even when performed by experienced operators. Even if the transvenous extraction using laser sheath seems to be more effective, this strategy would be more expensive.

Considering the availability of several strategies for TLR and the cost heterogeneity of procedures, a cost assessment in real life of these therapeutic strategies is essential for an optimal choice of therapeutic strategies.

title: Rate of Prolonged Response After Stopping Thrombopoietin-receptor Agonists Treatment in Immune Thrombocytopenia: a Prospective Multicenter Open Study

acronym: STOP-AGO

summary:
Thrombopoietin-receptor agonists (Tpo-RAs) have profoundly changed the management of ITP. However, today, there are no international recommendations concerning the long-term use of these costly, potentially pro-thrombotic agents, and that could induce bone marrow fibrosis in case of prolonged treatment. Tpo-RAs have been thought to play only a supporting role in ITP management. But our center along with many other research centers, have reported unexpected cases of durable remission after Tpo-RAs discontinuation in adult chronic ITP. In these retrospective studies, more than 20 % of patients were able to achieve prolonged remission.

The purpose of this study is to demonstrate that a substantial proportion of ITP patients may achieve a prolonged response after Tpo-RA discontinuation.

The investigators developed, in this study, a standardized procedure to discontinue Eltrombopag and Romiplostim, wherein the dose will be slowly tapered to limit the risk of bleeding. In case of relapse after Tpo-RA discontinuation, the decision to start a new therapy will be based on the clinician's judgment.

title: Phase 1/2 Open Single-arm Monocentric Study Evaluating the Tolerance and Interest of Transient Opening of the Blood-Brain Barrier by Low Intensity Pulsed Ultrasound With the SONOCLOUD® Implantable Medical Device in Mild Alzheimer's Disease Patients (MMSE 20-26)

summary: In Alzheimer's disease (AD) an imbalance between the production and clearance of the ß-amyloid peptide is hypothesized as the driving event of the disease. The decreased clearance of Aß could be partly linked to a progressive dysfunction of the brain vasculature and of the blood brain barrier (BBB). Among many possible explanations for these failures of the multiple clinical trials evaluating innovative drugs in AD, one is the lack of target engagement, as none of these drugs is able to readily cross BBB. This barrier acts as a wall that actively and passively prevents the crossing of molecules between the blood and the brain parenchyma compartments. Only 0.3% of intravenously injected anti-Aß immunoglobulins reach the brain despite a half-life of 15-20 days. Low intensity Focal ultrasound associated to microbubble injection can open the BBB in a non invasive way. These openings are reversible in 2 hours to 2 days depending on the intensity of the ultrasound. Ultrasound opening of the BBB was initially used in a transgenic mouse model of AD to increase the brain delivery of an anti-Aß antibody. In this article, the Aß load was reduced in ultrasound treated brain region. Surprisingly it was then demonstrated that the simple opening of the BBB without any adjunct anti-Aß treatment was able to drive the same Aß clearance effects. This is probably linked to endogenous antibodies that are able to penetrate the brain parenchyma and target Aß plaques. Four opening sessions elicited positive promnesic effects in these mice. Our group conceived and developed a mean to easily, reproductively and innocuously open the BBB. A unique extra-dural ultrasound emitter (sonoCloud®) is surgically implanted in the skull under local anesthesia. It emits low intensity contact ultrasound (LICU) that are not deterred by bone and thus are able to open the BBB.Preclinical studies show the SonoCloud® device is safe and efficient as it allowed reproducible and repeatable opening of the BBB in rabbits, dogs and non human primates. Drugs up to 2000 Kilo Daltons (kDa) are able to cross the BBB to reach the brain parenchyma in which the concentration of Carboplatin was increased by 700% in the BBB opened region. No adverse event was evidenced both clinically, by EEG, Evoked potential, MRI, 18 Fluorodeoxyglucose (FDG) PET and histology in the primates after 7 bi-monthly sessions of LICU BBB opening. SonoCloud® and its external generator have been certified by the academic start-up CarThéra (APHP, UPMC). Our multidisciplinary skills (neurology, neurosurgery, neuroimaging, basic science departments in the same University hospital setting) and our previous experience of BBB opening in Man give us the unique opportunity to translate this procedure from neuro-oncology to AD which could 1) Have a positive effect on brain lesion load and symptoms by itself and 2) allow anti-AD (or more broadly, central nervous system) drugs to engage their targe

summary:
The most common motor deficiency after stroke or traumatic brain injury is hemiparesis. Most hemiparetic patients recover walking, but rarely with a speed permitting easy ambulation outdoors with family or friends. One of the mechanisms of gait impairment in hemiparesis is insufficient active hip flexion during swing phase, which leads to insufficient ground clearing at swing phase, with associated gait slowness and risks of fall.

The main hypothesis behind the present study is that insufficient hip flexion during hemiparetic gait is partly due to overactivity of rectus femoris. Focal treatment of lower limb muscle overactivity using botulinum toxin has not been demonstrated to increase walking speed in hemiparesis as yet. However, most studies have focused distally, on improving foot dorsiflexion only. The purpose of this study is to compare the effects of botulinum toxin injection and placebo in rectus femoris (RF) + plantar flexors versus plantar flexors only.


title: Cognitive Adaptation and Frontal Cortex

acronym: ADAPCO

summary: A hallmark of our survival in the real world and of our capacity to navigate the complex social interactions of human society is our ability to show behavioral adaptation. Adaptation can be necessary for a number of reasons, making the study of the process challenging. Two classes of event can signal a need for adaptation: 1) Events caused by one's own actions and specifically FeedBack -FB- from those actions (e.g. the investigators adapt their strategy after an erroneous choice), and 2) Events not linked to our actions, specifically Action-InDependent Events -AiDE- (e.g. the investigators adapt their strategy after a change of rule). These two types of information - FB and AiDE - will frequently occur concurrently. A critical and difficult part of adapting appropriately involves resolving the difference between the two. So for example an incorrect FB can occur because the investigators made an error, or because something unexpected in the environment has changed -the rule switched, someone cheated, etc. The Investigators must work out which it is, as they will frequently require different behavioral adaptations. Their task is made even more complex by the fact that the dynamics of evidence accumulation after FB vs AiDE are very different. FB has a direct temporal and causal link to an executed action, which means that the investigators are certain to derive information about a given action from a given FB. In contrast, AiDE have no such contiguity and no initial relation to actions, which means that the investigators must accumulate evidence to identify the appropriate adaptation to an AiDE. So the crucial dilemma is this: after an unwanted outcome, should the investigators adapt as if they made an error and received a negative FB, or should they continue to accumulate evidence as if there has been an AiDE to which they need to know how to adapt. Animals are able to resolve this credit assignment problem, as evidenced by their ability to appropriately adapt their behavior. A breakdown of this ability to link unexpected events to their correct cause would seem to be at the source of impairments in a wide range of psychological and neurological disorders, from addiction and OCD to psychological symptoms in Parkinson's disease. Yet the neural basis of this process is currently unknown, and FB and AiDE processing have been assessed separately so far. ADAPCO will provide unprecedented characterization of brain systems critically involved in learning from and adapting to FB, AiDE, and their interactions, thanks to fMRI studies.

title: Structure-function Relationships Within the Cingulate Cortex

acronym: EEG-Feedback

summary: Efficient evaluation and monitoring of actions and outcomes are a key feature of primates' efficient adaptive cognition. Deficits in evaluating one's own actions and their consequences is a key feature of prominent disorders such as obsessive compulsive disorders (OCD), schizophrenia, and anxiety. The Investigators know that these evaluative processes implicate medial structures of the brain that are related both to old limbic functions and to more recently evolved higher executive functions. Brain potentials related to performance monitoring have attracted a lot of interest in cognitive neuroscience but also in the clinical domain because they appear to be altered in different neurological or psychiatric disorders, such as schizophrenia, OCD, or anxiety, and could become biomarkers of pathologies. But the neural sources of these markers are not fully determined and are currently highly debated. In addition, our work suggests that non pathological factors, such as normal morphological cortical variations, could affect those markers. Understanding performance monitoring, acting directly on medial cortex, or using electrophysiological markers in clinic are thus currently problematic and challenging. This is mostly because structure-function relationships in the medial wall are ill defined for historical, conceptual, and methodological reasons. Importantly, although individual variability of brain morphology impedes precise assessment of structure function relationships, this variability is almost never taken into account. EEG-Feedback aims to resolve these issues by evaluating the consequences of individual variability in cingulate cortex morphology on 1) surface EEG markers of feedback monitoring and 2) functional connectivity patterns thanks to resting-state fMRI.

title: Intracellular Phosphate and Adenosine Triphosphate (ATP) Concentration Evolution by Magnetic Resonance (MR) Spectroscopy in Patients During Hemodialysis

acronym: CIPHEMO

summary:
End-stage renal disease is associated with hyperphosphatemia due to a decrease of renal phosphate excretion. This hyperphosphatemia is associated with an increase of cardiovascular risk and mortality. Thus, three therapeutic options have been developed: dietary restriction, administration of phosphate binders and phosphorus clearance by hemodialysis (HD).

During a standard HD session, around 600 to 700mg phosphate is removed from the plasma, whereas it contains only 90 mg inorganic phosphate (Pi); 85% of phosphate is stored in bones and teeth in hydroxyapatite form, 14% is stored in the intracellular space (90% organic phosphate and 10% Pi), and 1% remains in the extracellular space.

Currently, the source of Pi cleared during HD remains to be determined. Phosphorus (31P) magnetic resonance spectroscopy allows reliable, dynamic and non-invasive measurements of phosphate intracellular concentration. The investigator's team recently published data obtained in anephric pigs, suggesting that phosphate intracellular concentration increases during a HD session. In parallel, we showed that ATP intracellular concentration decreased. These results suggest that the source of Pi cleared during HD could be located inside the cell.

In this study, investigators will measure intracellular phosphate and ATP concentrations and intracellular potential of hydrogen (pH) evolution during hemodialysis in 12 patients suffering from end-stage renal disease by MR spectroscopy.

If these results were confirmed in humans, it could explain, at least in part, HD intolerance in some patients and would lead to modify therapeutic approaches of hyperphosphatemia, for example, by modifying HD sessions time.

title: Evaluation of an Online Tool (COBPeer) Dedicated to Junior Peer Reviewers for Assessing the Reporting of Randomized Controlled Trial Reports

summary:
The peer review process is a cornerstone of biomedical research publication. Despite being essential, the assessment of the completeness of the reporting and the identification of switched outcomes are not appropriately performed. Furthermore, these tasks do not suppose a high level of expertise and could be performed by junior researchers.

To assess the completeness of reporting and identified switched outcome(s), junior peer reviewers could use a simple online tool (COBPeer) based on the CONSORT (Consolidated Standards of Reporting Trials) 2010 checklist and Elaboration and Explanation publication for reporting parallel-group RCTs. The tool would feature bullet points eliciting the meaning of each checklist item. The aim of this study that will compare the accuracy of junior peer reviewers using the tool to that of usual peer reviewers when evaluating the completeness of reporting and switched of primary outcome(s) in reports of RCTs

summary:
The aim is to reduct spontaneous use an activities of daily living of the paretic upper limb after stroke i six months after patient discharge from rehabilitation center. The level of functional recovery at rehabilitation discharge could better guide rehabilitation strategies to enhance independence and participation in daily life.

This study aims to determine, in patients after stroke, the optimal affected upper limb recovery threshold at rehabilitation discharge to predict spontaneous level of use of affected upper limb in activities of daily living, six month later.

This study is a multicentric prognostic prospective cohort study. The main prognostic variable will be the Action Arm Test (ARAT, Lyle, 1981) score at rehabilitation discharge and the predicted variable will be the Motor Activity Log - 28 (Taub et al. 1993) score at 6 months post discharge.

title: Stool Ritual: Impact on the Number of Nights Without Stools Among Dependent Residents in Institutions for Dependent Elderly People

acronym: RITUELIM

summary:
As they age, the intestinal elimination function can be altered by external factors. Sleeping is also a vital need for maintaining health. Sleep time varies with age (from 18h / day for an infant to 7h30 on average for an adult) and sleep disorders increase with age (INSERM source). In our study, the night is from 9 pm to 7 am, corresponding to the working hours of the night shift. Between 42% and 50% of episodes of wakefulness of more than 4 minutes in EHPAD are due to noise, light or the practice of care related to incontinence. 87% of all incontinence care practices have been associated with wake-up episodes. A personalized day care program would allow residents to improve the quality of their sleep by minimizing stools at night and therefore interventions by caregivers.

The ritual of stools, can be defined as the set of rules to observe to defecate in good physiological, physical conditions:

Be in a suitable place for intestinal elimination: personal bathroom preferably on the toilet or on a pierced chair that will perhaps be more secure and comfortable with the armrests. The position to be taken is important.
Propose a small bench to put under the feet to raise the knees higher than the hips and increase the abdominal pressure.
Preserve the visual and auditory intimacy of the resident at the time of defecation. Failure to do so may result in the person repressing his desire to defecate.
Allow the resident the time needed on the toilets the doorbell at hand and with the assurance that the caregiver will come back in a short time. Do not press it and do not forget it, privilege the autonomy and check that there is toilet paper.

The establishment of the stool ritual is not intended to reduce the amount of stool by day, but it aims to postpone the nighttime exemption on the day, and does not prevent the stool emission to other times of the day or night.

title: Clearance of Acetate During Fluid Resuscitation of Critically Ill Burn Patients: The CARE Trial.

acronym: CARE

summary:
Balanced solutions with low chloride concentration could represent an alternative to high chloride concentration solutions. Such balanced solutions contain other acid as buffers (i.e. acetate and/or gluconate). However, acetate has been associated with alteration of cardiac function when used as buffer in dialysate when high acetate concentrations are used and could promote the development of metabolic acidosis if it accumulates. Therefore, the safety of such solutions remains poorly explored. Because critically ill patients receive large amount of fluid during the early phase of resuscitation, large amount of acetate are to be administrated if such solutions are used. While acetate-containing solutions have been suggested to be safe in this setting, studies are still lacking regarding clearance and accumulation in critically ill patients.

It is expected to include 28 patients, the objective to analyze the data of 20 patients.

title: Impact of Empaglifozine on Cardiac Ectopic Fat

acronym: EMPACEF

summary: There is substantial evidence supporting the fact that ectopic fat accumulation is an important contributor to type 2 diabetes complications and cardiovascular risk [1]. Epicardial adipose tissue (EAT), located between the myocardium and the visceral layer of the pericardium has been associated with atrial fibrillation and with coronary artery disease [2, 3] and its abundance predicts the number of cardiac events within 8 years [4]. In addition, myocardial steatosis has been shown to be an independent predictor of diastolic dysfunction [5] [6]. Furthermore, in type 2 diabetic patients, bariatric surgery can reduce cardiac ectopic fat accumulation and improve cardiac function [7] [8]. When added to standard care, 10 or 25 mg/d of empagliflozin, an inhibitor of sodium-glucose cotransporter 2 (iSGLT2), significantly reduces the risk of death, cardiovascular death, and hospitalisation for heart failure among individuals with type 2 diabetes and established cardiovascular disease when compared to placebo [9]. The mechanisms of empagliflozin-improved cardiovascular outcomes in type 2 diabetic patients at high risk of cardiovascular events are not known. We hypotheses that empaglifozin could modulate cardiac ectopic fat and cardiac metabolism in obese type 2 diabetic patients.

title: Biomarkers of Antidepressant Resistance - BIORESA

acronym: BIORESA

summary:
According to the WHO, major depressive disorders have become the second worldwide cause of disability. Treatment, long-term medication, leads to frequent resistance (up to 40%).

Establishing a cerebral molecular signature of depression is not feasible in humans (need for cerebral samples). The alternative is to use peripheral biological samples (blood, urine, saliva).

Metabolomic is the integrated and quantitative study of all the metabolites of a biological system. This aims to define the metabolic status of an organism for a particular condition.

Metabolites are derived from biological extracts (cells, tissues, serum, plasma, urine, etc.) and are detected by:

liquid or gas chromatography coupled to mass spectrometry (LC-MS, GC-MS),
proton nuclear magnetic resonance (1 H-NMR). The biomarkers resulting from these studies have become important diagnostic criteria, measured objectively and evaluated as indicators of a normal or pathological state, or even predictors of treatment efficacy.

This approach allows the discovery of biomarkers that best describe the status of a disease for better understanding and are usable in a context of individualized medicine, with effects on clinical practice and management.

title: Bioimpedance Variation of Free Flap for After Clamping - MONITRANS

acronym: MONITRANS

summary:
MONITRANS project consist of developing a monitoring technology of post-operative breast reconstruction by detecting thrombosis. Its aim is to reducing time spent in hospital by monitoring patients at home.

Thrombosis following to abdominal free flap harvesting for breast reconstruction is a rare phenomenon (with a 2 until 15 % frequency). Moreover, it leads to ischemia by limiting water intake in the plasma compartments. The investigator would like to prove, by this research project, that they are able to detect ischemia via bioimpedance technology.

During abdominal free flap harvesting for breast reconstruction, there are few minutes where the flap is clamped because of anastomosis on the recipient vessels. The investigators would seize the opportunity of this step, which is similar to vascular thrombosis, to measure bioimpedance variations.

Therefore they would like to measure variations of the flap bioimpedance before and after vascular section. Another purpose consists of developing an algorithm which will detect postoperative thrombosis.

title: Comparison of Peripheral Perfusion Level Between Two Groups of Newborns According to Their Infectious Status Defined by the Criteria of the Center for Disease Control and Prevention (CDC)

summary:
Despite advances in medicine, secondary neonatal infection remains a continuing concern because of the associated high morbidity and mortality. The usual mechanism of infection responds to the transmission of germs by the equipment used for care (eg, catheters) and by the hands of caregivers. In preterm infants in particular, some infections can also have an endogenous source, by translocation of colonization germs present in the digestive tract.

The first line of prevention of secondary infection corresponds to compliance with the rules of hand hygiene, work surfaces and equipment carried out, the effect of which on the control of the incidence of secondary infection is regularly demonstrated. When declared, bacterial infection should be treated as quickly as possible with appropriate and effective antibiotics to preserve the healing prognosis. Compared to the infant and the larger child, clinical signs of calling are atypical and discrete. In the absence of staff trained to monitor newborns specifically, there is a real risk of discovering the existence of the infection only at an advanced stage corresponding, among other things, to circulatory collapse. This risk is not completely excluded, even with experienced practitioners, because the positive signs are rude and may go unnoticed (eg, signs of calling such as fever are rare in the newborn). Support for early diagnosis of neonatal infection by automatic monitoring systems has reduced mortality by 30% in the units where it has been applied. This is probably due to the fact that early warning made it possible to start the antibiotic treatment earlier and to complete the bacteriological diagnosis in order to better orient the therapeutic attitude. The best criteria for early diagnosis by automated systems were provided by the statistical analysis of cardiac variability, the results of the research and correspond to the standard deviation, the asymmetry and the entropy of the series d Cardiac intervals. Since microbial aggression has an impact on many vegetative variables outside of the electrocardiogram, our current research aims to determine whether the analysis of the perfusion index (PI) Which are of interest for detecting disturbances in the early stages of infection in newborns. IP corresponds to the ratio of the amplitude of the oscillating phase to the intensity of the constant part of the opto-plethysmography wave; It is obtained from signals recorded in a non-invasive manner by the same infrared sensor for pulse oximetry.


title: Mortality of Patients Undergoing Fracture of the Upper Extremity u Femur at the University Hospital of Amiens

summary:
Fractures of the upper femur (EFSF) represent a major public health problem in the elderly. Approximately 1.6 million patients are victims each year of an EFSF and this number is increasing as a result of the aging of the population.

In a recent Amiens retrospective study the mortality was estimated to be 22.5% at 1 year of the fracture. In surviving patients, the impact on loss of autonomy and degradation of quality of life is considerable.

The reduction of the incidence of post-operative complications includes the identification of risk factors.

No prospective study in Amiens has investigated the mortality and the study of the variables involved in the prognosis and long-term mortality of these patients.

By investigating this, our scientific goal is to more generally identify the mechanisms and biomarkers of health and mental well-being. Therefore, the investigators use non-invasive imaging like Magneto-EncephaloGraphy (MEG), ElectroEncephaloGraphy (EEG), functional and anatomic Magnetic Resonance Imaging (MRI; including Diffusion tensor - DTI). These brain measures will then be linked to behavioral measurements. Experimental methods (i.e., simple computer tasks) will be used to measure attention, conscious perception and regulation of pain and emotion.

title: Reduced Time on Floor After Falls at Night of People Living in Long Term Care Facilities - NoDelayFall Study

acronym: NoDelayFall

summary:
In the context of reduce staff for supervision of dependent elderly, automated risk alert systems could have a positive impact on the organization of night care by better targeting monitoring. Residents' sleep could be less affected with use of automatic alert system than by systematic monitoring visits. One study shows an improvement in the humor of residents after the use of such a system.

The hypothesis of the study is that the use of a bed-raising detection system linked with the activation of a lighting environment and a caregivers alert system (Etolya-F® gerontechnology device, Anaxi Technology Company) would reduce intervention time in this population, thus limiting the time spent on floor and its physical and psychological consequences.

title: Clinical Situations Leading to the Prescription of Neuroleptics by General Practitioner in the Elderly. Practice Survey

acronym: NEUGERPRAT

summary:
Behavioral disorders of psychiatric or neurological origin in the elderly are an emerging public health problem. Its management can include a prescription of psychotropic drugs (anxiolytics, hypnotics, neuroleptics, antidepressants for the most part). Many studies highlight the misuse of psychotropic drugs in this specific and vulnerable population, as well as the need for targeted actions.

As for neuroleptics, there is a deleterious over-prescription in the so-called productive behavioral disorders (cries, agitation, aggressiveness, ambulation), in particular in the patient with Alzheimer's disease (80% of patients) or related. The same applies to behavioral disorders in an acute episode of confusion, which also constitute a situation for the prescribing of psychotropic drugs in the elderly. The frailty of the elderly associated with neuroleptics is the cause of a significant iatrogenic (falls, confusions, excessive sedation, etc.), iatrogeny is largely avoidable.

There is little data on the representation of behavioral disorders in the elderly, whereas the recognition and management of behavioral disorders are functions of the tolerance of the entourage and the training of the caregivers. Significant data exist in the literature about diagnosis, risk factors, factors favoring or triggering behavioral disorders and somatic pathologies to be sought urgently.

The available recommendations on the drug treatment of behavioral disorders are complex and inappropriate in light of new data, including the dangerousness of psychotropic drugs. The deleterious effect of long-term drug treatments is proved. There is no validated drug strategy, especially in acute confusions of the elderly.

One study showed that there was a change in the type of neuroleptic prescribed between 2003 and 2010. Half of the general practitioners studied during this period switched from a first-generation neuroleptic to a second-generation neuroleptic. Nevertheless, the type of molecule chosen remains at the discretion of the treating physician or even required a psychiatric opinion or a passage in the emergencies. In the case where the practitioner initiates a prescription in office, in the home or in EHPAD, certain situations require the choice of a neuroleptic with or without pre-therapeutic assessment.


title: Characterization of Mesenchymal Stem Cells From the Colon and Small Intestine of Patients With Inflammatory Bowel Disease - The COSMIC Study

acronym: COSMIC

summary: The exact origin of inflammatory bowel disease (IBD) is still unknown. The current hypothesis is that IBD is secondary to an abnormal intestinal immun response directed to all or part of the intestinal flora in genetically predisposed individuals. Several experimental studies have demonstrated the ability of mesenchymal stem cells (MSCs) from bone marrow or adipose tissue origin to control intestinal inflammation in animal models. However, to date, there are no data regarding the functions of resident MSCs in the colon and small intestine of IBD patients. We hypothesize that dysfunction of resident intestinal MSCs contributes to the disruption of intestinal homeostasis in patients with IBD causing the development of intestinal inflammation. The aim of this research project is to identify, describe and characterize at the molecular and functional level MSCs of the colon and small intestine of patients with Crohn's disease and ulcerative colitis and to compare them with a control population.

title: Morphometric Study of the Muscles of the Skin in MRI 3 Tesla in Patients With Facial Paralysis.

acronym: SIMOVI IRM 2

summary:
The problem posed is the possibility of objectively assessing facial muscle mobility.

Today, in patients with facial paralysis, the assessment of the deficit is carried out using a subjective scale such as the House Brackman [1] or EMG scale of the facial nerve but does not distinguish each muscle individually . Objective measurements of skin muscles such as thickness and volume, in preoperative assessment of a facial paralysis rehabilitation surgery, would be useful in order to choose the most appropriate surgical technique. Indeed, too much amyotrophy will contraindicate hypoglosso-facial anastomosis (VII-XII) and it will be preferable to propose a temporal elongation myoplasty or a reinfused free muscle flap.

Similarly, it would be useful to be able to objectively evaluate the recovery of muscle function after facial allo-transplantation.

Although electromyography has been developed since the work of Duchenne de Boulogne, little research has been carried out on the development of noninvasive methods to objectively characterize in vivo skin muscles (variation, position, orientation, morphometry). The main morphometric data of the skin muscles come from anatomical dissections.

Imaging of the skin muscles has not been specifically developed. Some studies have been carried out to visualize these muscles in MRI 1.5 Tesla in pathologies such as myasthenia gravis, facial paralysis, and labio-alveolo-palatine clefts for example.

The originality of the project is to develop a method allowing to establish a quantitative correlation between the movements of the face and the muscular changes. This correlation will be achieved by associating muscular morphological data derived from MRI acquisitions and cutaneous deformations resulting from clinical examinations. This non-invasive approach should make it possible to establish objective and reproducible indicators in patients with facial paralysis sequelae.


title: Astrocytoma / Desmoplastic Gamliogliomes (DIA / DIG) - Study of the French Cohort of the Last 20 Years : Clinical, Anatomopathological, Molecular and Radiological Charactersics

acronym: DIA/DIG

summary:
Astrocytomas / infantile desmoplastic gangliogliomas (DIA / DIG) are rare brain tumors usually affecting infants. They represent about 0.5% of all pediatric brain tumors. DIA / DIG occurs mainly in the first 2 years of life, with a sex ratio M / F of 1.7 to 1. From a histological point of view, DIA / DIG are neuroepithelial tumors. These tumors may have a purely astrocytic differentiation (DIA) or be composed of tumor cells with astrocytic and neuronal differentiation (DIG). The desmoplastic component is usually adjacent to the meninges and is defined by the increase or modification of connective tissues related to the presence of neoplastic cells with the formation of a collagen-rich extracellular matrix.

Due to their benign biological behavior and favorable clinical course, they are classified in benign tumors, ie grade I according to the WHO classification. However, all tumors called DIA / DIG do not behave in a benign manner. Cases of metastatic cerebrospinal and malignant disorders have been described. It appears that about 40% of DIG cases require additional medical treatment such as chemotherapy, radiotherapy and / or new surgery, and 15% of infants and children with GIDD die from the disease. It is possible that what is grouped within the DIA / DIG is a heterogeneous group of tumors, evolution and prognosis very variable.

The cytogenetic knowledge of DIA / DIG is very limited and is only available on small numbers of cases. Cytogenetic analyzes of several cases of DIG showed normal karyotypes. More recently, a CGH-Array study of 3 cases of DIA / DIG did not find any significant chromosomal gains or losses.

It has been shown, however, that a mutation involving BRAF (BRAF rearrangement or BRAF V600E mutations) was a recurrent element in low grade gliomas, particularly in pediatric patients.

It is also suggested that deregulation of BRAF activity in some DIA / DIG may indicate the importance of the MAPK (mitogen-activated protein kinase) pathway in signaling pathways for DIA / DIG development. However, data on the link between the BRAF gene and DIA / DIG remains very limited. Thus, further studies are needed to study the other members of the MAPK pathway in DIA / DIG (eg PI3K / AKT / mTOR). This could provide new therapeutic possibilities involving targeted therapies specific to the MAPK signaling pathway.

It appears that DIA / DIG does not all behave in a benign manner and some would undergo a malignant transformation that could be due to chromosomal alterations such as, for example, TP53, PI3K. In addition, because of the limited number of cases, it would be interesting to study the characteristics of patients with DIA / DIG in order to study their characteristics and whether there are clinical, pathological, cytogenetic and / Molecular forms between benign and malignant forms.


title: Evaluation of Circulating Tumor DNA as a Theranostic Marker in the Management of Glioblastomas.

acronym: Bi-GLAM

summary:
Glioblastomas (GBM) are rare tumors of poor prognosis and their treatment is based on surgery followed by radiochemotherapy. Clinical and imaging evaluation is not always straightforward: the more or less complete surgery, the pseudo-progression after radiochemotherapy, the radionecrosis, the diagnosis of the relapse and the follow-up under anti-angiogenic can pose problems Clinicians and radiologists. Accessibility to a plasma tumor molecular marker would greatly facilitate the follow-up of these patients.

It is now established for many cancers that circulating tumor DNA (cTNA) has the same molecular abnormalities as those identified in the primary tumor cells. Numerous studies have shown the prognostic value and diagnosis of the exploration of cDNA.


title: Descriptive Study of the Evolution in Proportion of Regulatory B Lymphocytes in Patients Hospitalized in Intensive Care for Severe Sepsis

acronym: DELyBREG

summary:
Severe sepsis and septic shock are the most severe forms of sepsis (which associates a systemic inflammatory response with infection). These are serious pathologies with a lethality estimated at almost 40% at 28 days (after the onset of sepsis).

After a first pro-inflammatory phase, a second compensatory phase called Compensatory Anti-Inflammatory Response Syndrome (CARS) takes place quickly. Patients then show signs of immunosuppression and profound alterations in immune functions. It is during this phase that the vast majority of deaths occur, far from the onset of the shock, which is related to the inability of the immune system to eliminate the initial infectious agent and / or a greater susceptibility Important to develop secondary infections (nosocomial infection, latent virus reactivation ...).

The CARS phase has been the subject of studies focusing on measuring the plasma concentration of anti-inflammatory cytokines (such as Interleukin (IL) -10), the percentage of regulatory T lymphocytes (Treg), Or the percentage of monocytic expression of HLA-DR in septic patients.

The investigator proposes to carry out the first study on a newly described regulatory lymphocytic subpopulation: regulatory B lymphocytes (Breg) from a quantitative and functional point of view in severe septic states.


title: Study of the Prevalence of Complications Occurring in the Mother-newborn Couple During the First Month After Returning Home, Since the Introduction of Standard Outpatients (According to HAS 2014 Recommendations) at the Amiens-Picardie University Hospital

acronym: COMPLISTAN

summary:
Prior to the HAS recommendations of March 2014, the "mother - newborn" couple was discharged from the maternity home at 4 days after delivery by AVB and 5 days after caesarean section.

The stay in maternity allowed a follow-up of the newborn whose weight gain and the occurrence of a jaundice; And monitoring of the mother whose milky ascent and psychological feelings.

In March 2014, the HAS published new recommendations on maternity leave arrangements for the "mother - newborn" couple, the organization of postpartum follow - up for the mother and pediatric follow - up for the newborn. The HAS then defines so-called "optimal" conditions for so-called "standard" outputs, with 9 criteria to respect respectively for the mother and the newborn.

If the mother-to-newborn couple respects these so-called optimal conditions and is eligible according to the respective criteria, the latter leaves at home after 72 hours and before 96 hours for an AVB and after 96 completed hours and Before 120 hours for caesarean delivery.

As no pediatric discharge was done in the afternoons at the maternity hospital of Amiens, an arbitrary choice was made to allow a "standard" release to the "mother-newborn" couple only if the child was born between 00H00 and 11H59 so that his clinical examination of exit is carried out at 72 hours of the birth as recommended by the recommendations of the HAS.

These recommendations being recent (2014), no study has studied the impact and consequences on the triad "father / mother-newborn" of these exits including the occurrence of possible complications or events: re-hospitalizations again The early termination of breastfeeding, and whether the follow-up procedures advocated by the HAS are being followed.


title: Comparison of the Efficacy of a Protocol for the Withdrawal of Neurosedation From the Usual Strategy in Cerebroses: Randomized Controlled Trial.

acronym: NEUROSEV

summary:
The withdrawal syndrome in benzodiazepines and morphine is common in intensive care, the incidence is estimated at 32.1%.

Cerebrospatized patients are probably more prone to withdrawal because they require high doses of sedation.

Moreover, this syndrome is probably deleterious on the cerebral hemodynamics (high point of the therapeutic management).


title: Study of the Impact of VEGF Polymorphism on the Development of Renal Carcinoma in Renal Transplant Patients

acronym: VE-CART

summary:
Renal transplant patients have on average 3-5 times more risk of developing cancer than the general population. This rate can be increased up to 10 to 15 times in some type of cancer like kidney cancer. Among the identified risk factors, immunosuppressants and, in particular, calcineurin inhibitors (ciclosporin and tacrolimus) play a major role in increasing cancers apart from their depressant effects on the immune system.

Calcineurin inhibitors (CCN) are the basis of immunosuppressive therapy in renal transplantation. Several mechanisms have been implicated to explain their pro-oncogenic properties. One related to an increase in VEGF expression seems particularly interesting in the study of renal cell carcinoma in the transplanted patient. Indeed, the physiopathology of kidney cancer has clearly been associated with an increase in the production of VEGF. Furthermore, some polymorphisms of the gene encoding VEGF have already been associated with the survival of patients with renal carcinoma and the circulating level of VEGF in the general population. The search for an association between the polymorphisms of the VEGF gene and renal carcinoma in renal transplant patients could thus identify patients whose risk of renal cell carcinoma (cRCC) post-transplantation is increased. If the involvement of certain polymorphisms in the development of cRCC was confirmed in this population, their research before the introduction of the immunosuppressive treatment would make it possible to direct the choice of treatment towards molecules without pro-oncogenic property in the Patients such as mTOR protein inhibitors (sirolimus, everolimus). This research project is therefore in line with the desire to move towards a more "personalized" medicine that could be beneficial for the patient.

title: Evaluation of the Measurement of Cardiac Output by the NEXFIN HD Monitor in Peroperative

acronym: NEXFIN

summary:
Continuous perioperative cardiac output (DC) and blood pressure (PA) monitoring contributes to hemodynamic stability and ensures adequate perfusion pressure, resulting in a reduction in morbidity and mortality and length of hospital stay.

The monitors usually used in perioperative are either semi-invasive and difficult for calibration (oesophageal Doppler) or invasive (arterial catheter).

The Nexfin HD allows these two measurements and it is completely non-invasive, remains to validate its use in peroperative.


title: Patient-ventilator Asynchrony During Noninvasive Ventilation Assessed Using Diaphragm Ultrasonography

acronym: ADULT

summary:
Fifteen healthy subjects under non-invasive ventilation will be have a recording of surface electromyogram, measurements of airway flows and pressures as well as a continuous ultrasound. The provocation of leaks on the Ventilation circuit and expiratory trigger modulation will generate a number of asynchronies between the subject and the respirator.

These records will help to assess the agreement between the detection of asynchronies using electromyography of the respiratory muscles (technique of reference) and the diaphragmatic echography. We will also compare the respective performance of two techniques of diaphragmatic exploration (excursion and thickening of the diaphragm). A sensitivity of Ultrasound technique of at least 90% will be interpreted as a satisfactory index of concordance.

summary:
Autoimmune diseases represent a heterogeneous group of pathologies whose etiopathogenic mechanisms are most often unknown. Autoimmune diseases are the leading cause of morbidity and mortality in young women and autoimmune thyroid diseases are the most common.

Viral infections are the main environmental factors suspected of triggering autoimmune diseases. Several viruses are certainly involved, all of which are possibly capable of triggering an autoimmune response. However, the precise identification of the viruses involved remains to be established.

It has been shown for the first time by the 2005 PHRC that enteroviral RNA is present in perioperative specimens of thyroid tissue. However, this case-control study did not show any difference between the thyroid group and the group other thyroid pathologies It has been recently published that Parvovirus is possibly involved in thyroiditis: the parvoviral genome is present in the thyroid tissue of Hashimoto thyroiditis operated and more precisely is present within the thyrocytes itself.

title: Randomized Controlled Non-inferiority Trial Assessing the Osseointegration of THA Grafted by PolyNASS (ACTISURF-CERAFIT® ) Versus Non-grafted THA (CERAFIT®)

summary:
The infection rate after Total Hip Arthroplasty (THA) is about 1%. It is a serious condition, with high morbidity, sometimes fatal, requiring costly treatment.

The treatment is difficult because "biofilm" forms very early after the bacterial contamination of the prosthesis.

Prevent infection means reduce or prevent the formation of bacterial biofilm and controlling protein response to allow osseous-integration of the prosthesis.

A new prosthesis was developped, grafted by PolyNaSS (polysodium styrenesulfonate). This bioactive polymer allows to substantially reduce bacterial adhesion, biocompatibility, bio-integration in preclinical studies. This first clinical study aims to compare the osseous-integration of this prosthesis to the same prothesis with no grafting.

title: Construction and Validation of a Functional Score for the Detection of Ruptures of the Anterior Cruciate Ligament in the Immediate Post-traumatic Period

acronym: ACL-TS

summary:
This study develops the construction and validation of a reliable functional screening score in LCA ruptures in the immediate post-traumatic period.

This score, realizable in an emergency, would be an early warning signal requiring an emergency consultation with an orthopedic surgeon. It would be a tool for screening acute LCA ruptures at a time when ligament testing maneuvers are too painful to be contributory to the diagnosis. It would avoid a premature return to dangerous activity for the knee with a rupture of the LCA.

The other impact would be economical since it would avoid the realization of unnecessary MRI.

On the other hand, it will allow patients with LCA rupture to have faster access to MRI. The hypothesis of the study is that a validated functional score would make it possible to sort the patients in the emergencies and to prescribe the MRI only in the cases of effective rupture of the LCA.

title: Analysis of the Role of Hepatocyte SLAMF3 Receptor and Drug Resistance Proteins (MDR) in Resistance to Treatment With Sorafenib in CHC Patients

summary:
Primary liver cancer or hepatocellular carcinoma (HCC) is the 7th most common cancer in humans; 9th in women (figures from the Association for Research against Cancer ARC). This cancer is a major public health problem on a global scale. Patients, whose diagnosis is often late, are at advanced stages of the pathology, even those who benefit from locoregional treatments have a poor prognosis and suffer from a lack of curative therapeutic strategies. CHC is highly refractory to cytotoxic chemotherapy and so far the response rates to conventional systemic chemotherapy has provided a clinical benefit where survival was prolonged by more than 25% in patients with advanced CHC. Further efforts are needed to effectively manage HCC. Knowledge of the mechanisms regulating proliferation and inhibiting the sensitivity of transformed cells to apoptosis is the key to the development of more effective therapeutic strategies.

Several new therapies, called targeted therapies, are tested in clinical trials. Currently, the most effective molecular agent for targeting the Raf pathway is sorafenib capable of also inhibiting tyrosine kinases of VEGFR and PDGFR. Sorafenib, a multikinase inhibitor, decreases the proliferation of tumor cells in vitro that inhibit the activity of targets present in tumor cells (CRAF, BRAF, V600E BRAF, c-KIT, and FLT-3) and tumor vascularization VEGFR-2, VEGFR-3, and PDGFR-beta). Despite the real benefit of this treatment, its efficacy (three months of overall survival) and its indication remain limited to Child-Pugh A, WHO 0-2 patients in whom curative treatment is contraindicated. In addition, several patients have resistance to Sorafenib and thus find themselves in therapeutic failure, thus limiting the therapeutic choice for these patients.

Resistance to treatment with Sorafenib limits the therapeutic choice. The mechanisms responsible for this resistance remain to be elucidated. Drug resistance proteins, MDR Multi-Drug Resistance, is a family of molecules whose expression increases in the cancer cell and ensures the repression of chemotherapy molecules outside the target cancer cell. This family includes the proteins ABCG2, MDR and MRP1. Our in vitro studies show that treatment of CHC Huh-7 cells with Sorafenib (10 mM) induces the specific expression of the transcripts of the MRP-1 protein without any effect on the expression of the ABCG2 and MDR protein. In addition, sorafenib has an effect on the expression of hepatocyte SLAMF3 receptor transcripts, a receptor recently identified in hepatocyte tissue. Indeed, it has been shown that the expression of SLAMF3 is lowered in the cancerous tissue compared to the healthy tissue and that the reintroduction of a strong expression in the cancer cell inhibits its proliferation by inhibiting the MAPK Erk pathway, Cancer cells to apoptosis and inhibits the uptake of tumor masses in the Nude mouse (I. Marcq, et al., 2013).


title: Prognostic Impact of the Location of Mitral Valve Prolapse on the Long-term Results of Mitral Plasty

acronym: IPPVM

summary: Mitral insufficiency (MI) accounts for 24% of adult valvulopathies and affects 7% of subjects older than 75 years. They are the second leading cause of valvulopathy in Europe. The most common etiology is the associated valvular prolapse. Mitral surgery remains the reference treatment for symptomatic MI. The success of this procedure depends on the mitral valve geometry and the location of the prolapse. The site of the prolapse, whether monovalvular, localized to the posterior or anterior leaflet, or bivalvular, influences the possibilities and probably the long-term results of the plasty.


title: The Long-lasting Effects of Repetitive Neck Muscle Vibrations on Postural Disturbances in Standing Position and on Spatial Frame Reference in Chronic Stroke Patients

acronym: VIBR-HEMI

summary: One of the causes of disability in patients suffering from a stroke is postural imbalance. Sensory stimulation improves the postural symmetry of the subject transitorily and they are thought to have an effect on the spatial frame of reference through a sensory recalibration. Studies have shown that sensory stimulation by vibration of neck muscles have an immediate effect on static balance and when walking. The objective of this preliminary study is to test the long-lasting effects of repetitive neck muscle vibrations on postural disturbances in standing position and on spatial frame reference in chronic patients.

title: The Value of 99mTc-Leukoscan® Scintigraphy in the Diagnosis of Infectious Endocarditis on Surgical Materials

acronym: PLEIM

summary:
Infectious endocarditis is a serious pathology with difficult diagnosis especially on prosthetic valves or cardiac device because of the plurality of clinical presentations and the low sensitivity value of echocardiography in these patients. Despite a well validated indication for the detection of septic emboli, the value of FDG-PET for the detection of prosthetic valves or cardiac implantable device is still unclear especially because of frequent non-septic inflammatory processes.

To improve the specificity value, the use of radio-labeled leukocytes scintigraphy is conventionally proposed. An alternative method is to label leukocytes in vivo with an anti-murin anti body fragment ( Sulesomab , Leukoscan®). This scintigraphy is regularly used in the investigation of osteomyelitis and has been proposed in infectious endocarditis. To knowledge of investigators, the value of Leukoscan® scintigraphy on prosthetic valve or cardiac device infection had not been studied.


title: Prevalence of Sarcopenia in Chronic Obstructive Patients Hospitalized in Pneumology at the CHU of Clermont-Ferrand

acronym: SARCOBS

summary: The prevalence of sarcopenia is high in many organ pathologies such as COPD, but remains little studied in acute respiratory failure. Sarcopenia is a health problem representative of frailty, loss of autonomy and decreased muscle strength. The frequency and evolution of sarcopenia is unknown in patients having chronic bronchic obstruction with exacerbation.

title: Robot-assisted Lobectomy Versus Video-assisted Lobectomy : a Prospective Observational Study

summary:
This prospective and observational cohort studies the morphine consumption difference during the first 48 hours after a lung lobectomy between patients operated with a robot assisted or a video-assisted technique for a lung cancer lobectomy.

Second outcome was to search eventual cardiac output difference during the surgery in 100 patients (50 in each group) using a non invasive monitoring device of cardiac output

All patients operated between january 2016 and March 2017 for a lung cancer lobectomy were included.
