title: Biomechanical and Ultrasonic Assessment of the Achilles Tendon in Vivo (MEDUSAA)

acronym: MEDUSAA

summary:
Among Musculoskeletal disorders (MSD) the rupture of the Achilles tendon is the most common. Up today, the mechanical and elastic properties of the Achilles tendon are still unknown, and that both in healthy subjects in pathology. The viscoelastic properties or dynamic mechanical properties are directly related to the tendon of the health status and its elongation capacity.

The laboratory UMR Inserm U930 - CNRS ERL 3106 in Tours has developed a non-invasive ultrasonic device, named Achillus, which, via an ultrasonic probe, allowing to access the viscoelastic properties of the tendon during the contraction of the sural triceps.

This is what we want to do in this first protocol: in vivo observation of the normal values and variations, looking for changes related to hyper solicitation and finally trying to highlight a tendon fragility parameter for patients who have experienced of a Achilles tendon rupture.


title: Immunoregulation of Periodontal Diseases

summary: Periodontal diseases are a group of diseases that affect 15% of the population and in the absence of treatment causes tooth loss. Periodontal lesions are characterized mainly by strong inflammation and hyper-vascularization. Search in blood cells and inflammatory markers attempts to explain the etiological-pathogenetic mechanisms. Innate immunity can be assessed by qualitative and quantitative analysis of blood phagocytes, natural killer cells, complement, proteins of inflammation and cytokines. Current data from the literature on this subject give contradictory results and the comparison of studies are difficult because the diversity of the populations studied, evaluated cells and the methods used. The aim of the study was to evaluate the innate immunity of patients with periodontal disease and compare it with a group of patients without periodontal disease.

title: Ultrasound Guidance to Alleviate the Pain Associated With Intramuscular Injections of Botulinum Toxin in Spastic Patients

acronym: TOXINECHO

summary: Intramuscular injections of botulinum toxin are currently the best focal treatment of spasticity, with clearly defined indications and role. French and European recommendations focus on the toxin's mode of administration, which must be as precise as possible. The toxin's specific action on motor endplates (blocking the release of acetylcholine) shows the importance of targeted injections within the muscle belly. The pain caused by these injections is due partly the number of injections (up to 30 in a single session), and partly to the use of electrical stimulation guidance. Prevention and alleviation of the pain caused by these injections have become a regulatory obligation since the law of 4 March 2002 relating to the rights of patients and the quality of the health system (" Any person has the right to receive relief from pain, which must, under all circumstances, be prevented, evaluated, taken into account and treated … ").

title: Human Fine-motor-skills in Weightlessness: Comparison of a Laboratory and an Everyday-like Context

acronym: FINESKILL

summary:
The human performance during weightlessness was tested in a multiplicity of laboratory experiments during parabolic flights and in space. It is therefore known that human fine motor skills as grasping are affected by the impact of changing gravity levels. However, because everyday life movements differ in several aspects from those done in an experimental lab situation, investigators do not know until know if this kind of movements is altered in the same extend.

Fine motor skills seem to depend on the context in which they are made. Thus, the performance in weightlessness during everyday life could substantially differ from the results given by previous laboratory studies.

This assumption will be tested in the present project, with subjects executing one and the same grasping movement in two different contexts, both in normal gravity conditions and in weightlessness. To that end, the investigators developed a new method which allows comparing the same grasping movements under different conditions.

title: French Registry of Acute ST-elevation or Non-ST-elevation Myocardial Infarction 2015

summary:
Over the last two decades, considerable progress has been made in the management of myocardial infarction, both in the acute phase and in monitoring beyond the hospital phase. However changing practices in the "real world" and their impact on prognosis in the medium and long term patients admitted to the intensive care unit for acute myocardial infarction are relatively little studied exhaustively.

The study of clinical, biological and genetic characteristics of patients and their conditions of care, help to identify patients at risk for increased morbidity and mortality after myocardial infarction and could be the basis for the subsequent realization of specific studies on the optimal therapeutic management of the disease according to the different risk profiles.

title: Exploration and Characterization of the Phenotypic and Genetic Profile of Patients With Early Onset Schizophrenia Associated With Autism Spectrum Disorder and Their First-degree Relatives (GenAuDiss).

acronym: GenAuDiss

summary:
Early onset schizophrenia "early dissociative disorder" is a rare disorder with a low incidence of approximately (1/5000 to 1/20000). Its link with autism spectrum disorders remains unknown although both are serious neurodevelopmental diseases. As part of the 2011-2013 Interregional hospital Clinical Research program, University Department of Child and Adolescent Psychiatry Pediatric Hospitals of CHU de Nice Lenval identified patients with a complex phenotype characterized by an early schizophrenia associated with autism spectrum disorders and developmental disabilities in mild to moderate. This phenotype could be a new syndrome.

The goal of our project is to define the genetic causes of this phenotype. The technique of high throughput sequencing will be used to obtain the sequence of exomes of these patients and their families. This study will therefore be important to give an accurate diagnosis for patients and their families. Moreover, we believe that this project will identify new genes involved allowing a better understanding of the pathophysiology. Recent studies show the involvement of mutations in several genes (eg NRXN1 and UPF3B) in these different clinical phenotypes. However, the genetic basis of the childhood and early onset schizophrenia are much less well known than those of autism spectrum disorder

title: Interaction of Otolith Stimulation and Carotid Baroreflex in Humans

acronym: OTOBAR

summary:
It is well documented that a few days stay in space induces a change in the vestibular-ocular reflex reflecting a reinterpretation of sensory inputs following the disappearance of gravity. If the change of eye reflexes actually the result of a reinterpretation of sensory input, the investigators should also expect to see an alteration of the vestibular-cardiovascular reflexes. The modification of these reflexes may modulate the carotid baroreflex and thus participate in the post-flight cardiovascular deconditioning.

The first objective of this project is to study the carotid baroreflex under different supine (dorsal, ventral and lateral) inducing different otolith stimulation in normal-gravity.

title: Ultrasound Measurement of the Quadriceps Muscle Diameter for the Detection and the Follow-up of Malnutrition in Patients Receiving Mechanical Ventilation in Intensive Care Unit

acronym: MALICUS

summary:
Malnutrition is a major risk factor for morbidity and mortality of patients managed in intensive care unit. Early recognition and treatment of adult malnutrition are recommended in acute care settings especially for patients requiring mechanical ventilation. Biochemical indicators like serum concentrations of albumin and prealbumin (transthyretin) have a tradition of being used as markers of nutritional status but remains influenced by nonnutritional factors. A recent assessment of quadriceps muscle diameter with ultrasound method has gained interest for screening and follow-up of muscle weakness at the bedside in critically ill patients. In this light, the MALICUS project aims to investigate the validity of ultrasound as measurement tool for assessing malnutrition acquired in intensive care unit.

Skeletal muscle is central to cytokine regulation and it contributes 85% of total body glucose clearance. Some research findings suggest that muscle wasting is a smoldering inflammatory state partially driven by cytokines and oxidative stress but these conclusions need to be investigated in context of critically ill patients and perioperative settings.

The investigators search to determine impact of inflammatory biomarkers (IL-1, IL-6 and TNF-α) and oxidative stress (evaluated by quantifying the global anti-oxidative defenses in patient with an original method (Patrol® test) based on the use of excited molecular oxygen (singlet oxygen) as a source of ROS on erosion of lean body mass measure with quadriceps muscle ultrasound. Consequently, in an ancillary study of the MALICUS project, the investigators wish to investigate interaction between acute inflammation and muscle wasting.

title: Early Phase of Multi-disciplinary Prevention Program of Shoulder Pain Post-stroke

summary:
About 70% of hemiplegic patients suffer from hemiplegic shoulder pain after stroke. This common occurrence is a cause for concern in the rehabilitation setting as it leads to impairment of functional outcomes induced by discomfort and delays in rehabilitation, important psycho-emotional repercussions as there is a correlation between upper arm pain and depression, a longer hospital stay. Poor management of hemiplegic shoulder pain can ultimately give rise to type 1 "complex regional pain syndrome" (CRPS I). There is no consensus on treatment, care pathways or useful devices for positioning acute stroke patients in the literature. Our objective is to compare the effectiveness of a new positioning procedure of the hemiplegic arm with conventional positioning (pillow and "shoulder-immobilisation" sling) in acute stroke patients.

Patient's actions are focus in 4 points:

Positioning in bed, wheelchair and standing with specific materials (holds, sling in external rotation and abduction)
Be careful of shoulder's coaptation in care and functional activities (toilet, dressing, transfers)
A training of the patient and members of family on pathology, risk, use of material
Daily passive mobilisation of the upper member by a therapist.

title: The Operation of Control Devices During Parabolic Flights: Influence of Weightlessness, Stress and Motivation

acronym: Grafism

summary: The aim of this project is to investigate whether alterations in sensory-motor performances during weightlessness are only of theoretical relevance, or indeed restrict the capacity of the participants. To find out, volunteers will monitor a complex realistic process by operation of buttons and switches in weightlessness. The task will mimic the control of vehicles, research equipment and industrial processes. Effects of weightlessness will be separated from effects induced by stress and those of motivation through evaluation of cortisol and manipulation of motivation.


acronym: HYDRONAUT

summary: The scientific goal of this experiment is to evaluate the performances of our three-dimensional digital model by comparing its prediction computed from underwater data to posture observed during real weightlessness during parabolic flight.


summary: If investigators know that the anticipatory mechanisms involved in precision grip take into account the gravity, however it is unclear how they adapt to changes in the gravitational level. The objectives of this study are to study and model the movement control and the mechanisms underlying learning and adapting to the condition of weightlessness. Specifically, i) investigators will determine if a change in the level of gravity is taken into account when controlling grip force and ii) investigators will examine the effects of gravity change on hand-eye coordination.


title: Evaluation of 3D Selection Tasks in Parabolic Flight Conditions: Pointing Task in Augmented Reality User Interfaces

summary: During a space mission the crew has to perform a wide variety of tasks under different acceleration conditions. For handling of displays and control items during a mission, the astronaut's performance is strong depended on an intuitive usability. Currently investigators are exploring and developing different Augmented Reality interfaces for the International Standard Payload Rack (ISPR) Biolab that is installed in the International Space Station (ISS) module Columbus. Augmented reality (AR) is a live, direct or indirect, view of a physical, real-world environment whose elements are augmented by computer-generated sensory input such as sound, video, graphics or GPS data. Using AR technologies provides user-oriented support for working procedures in development, production, and operating of complex technical products and systems. It is conceivable that in future manned missions such interfaces will be applied to space operations, where the astronaut will handle virtual information that enriches the physical reality. To improve the support for the operational ground team and the space crew by performing service and maintenance tasks at the Columbus space laboratory Biolab, investigators explore innovative tridimensional (3D) interaction techniques that allow an intuitive way to interact with the virtual content. The developed AR interfaces for the ISPR Biolab ought to offer support while handling standardize service and maintenance procedures. This research is primarily focused on supporting the ground team during their work at the engineering model of Biolab that is located in Cologne at the Institute of Aerospace Medicine. Applying these interfaces subsequently to space operations requires previous exploration regarding the influence of different acceleration conditions that ought to be considered at the investigators' current stage of designing and development. Thereby one important aspect is focused on the correct placement of virtual user interfaces while interacting with it. To explore human adaption of handling and controlling virtual AR interfaces, this experiment denotes a usability study that will supply findings about human mental workload and sensorimotor coordination while performing the experimentation task under different accelerations of gravity. The proposed experiment will supply essential information about understanding the adequate quality characteristics concerning placement of virtual interfaces in physical reality and identify disturbing factors while applying in hyper-g and micro-g conditions.


title: The Effect of Gravity on the Muscular Control of Landing From a Jump

acronym: SLS-JUMP

summary:
In this project, investigators propose to study the jump in different reduced gravity fields obtained during parabolic flights profiles but also during increased gravity fields obtained during turns of the airplane or during the pull-up phase of the parabola. By means of a pneumatic device, an additional pull-down force will be added to the vertical force caused by the gravity field. By combining different levels of gravity to different levels of the added pull-down force it will be possible to dissociate the respective contribution of the otolithic and proprioceptive systems to the anticipatory landing response. To the investigators' knowledge, only one study has modified the gravity field during a jump. However, these authors did not add a pull-down force and only analyzed the vertical ground reaction force.

A better knowledge of the sensory-motor control of the landing phase of a jump will also increase the investigators' understanding of the physiopathology of joint instability. Indeed, similarities could be found between the evolution of the motor response due to the absence gravity during long-duration space flights and the pathological process of chronic ankle and knee instability. The knowledge generated by this study will thus provide invaluable information in the context of human performance and rehabilitation.


title: Interrupter Technique and Plethysmography Airway Resistance Measurement: Comparison of These Two Techniques for the Diagnosis of Airway Obstruction Diagnosis and Bronchodilation Response in Children 3 to 6 Years of Age

summary: In preschool aged children, the most suitable techniques to assess airway obstruction is debit interruption technic (Rint) and plethysmographic measure of specific airway resistance (sRaw). Even if Rint is easily and routinely performed, it also includes a component of lung tissue and chest wall resistance as well as respiratory tissue viscoelasticity. sRaw seems to be better for discriminating airway obstruction. These two techniques will be compared in terms of concordance in the diagnosis of pulmonary obstruction and bronchodilator response.

title: Interest of the Ultrasound to Evaluate the Quadriceps Muscle Wasting in Critical Ill Patients.

acronym: ECHOSCAN

summary:
Intensive care unit acquired muscle weakness (ICUAW) is a common disease. After 7 days of mechanical ventilation, a quarter of patients develop an ICUAW responsible of a 15-20% of muscle loss. This is a serious pathology associated with high morbidity and mortality.

Clinical diagnosis of ICUAW is difficult and need a patient awoken. CT scan and Magnetic Resonance Imaging (MRI) are considered as "gold standards" to quantify and monitor changes in muscle mass. But these tools are not adapted to ICU patients.

Ultrasound (US) is an easy access tool at the bedside to assess muscle mass and does not expose the patient to additional radiation.

The objective of this study is to evaluate the correlation between US and CT scan to measure quadriceps muscle thickness of ICU patients.

title: Gastroenteric Anastomosis With Natural Orifice Translumenal Endoscopic Surgery (NOTES) Using the New Fashionned Tissue Apposing Stent Axios® for the Treatment of Antro-pyloric or Duodenal Obstructions : Prospective Evaluation of Feasibility, Efficacy and Tolerance.

summary:
Achieving gastro-jejunal or duodenal anastomosis (GJA ) by exclusive endoscopically is a real goal for many years in the development and research of the transluminal endoscopic surgery (N.O.T.E.S). Endoscopic treatment, including palliative antro duodenal stenosis by metallic stent, although minimally invasive, causes problems in long-term secondary obstruction and migration. Surgical treatment of these strictures is associated with significant morbidity and mortality . The complication rate and severity of post-operative surgery after gastric bypass Roux-en-Y anastomosis or gastroduodenal fistulas remain close to 5% with a mortality of 1%. After 3 years of experimental research on porcine model, our team has developed a procedure of gastro duodenal anastomosis using transgastric endoscopic minimally invasive surgical technique (or NOTES) - LBA UMRT24 CERC laboratory , Aix-Marseille University , Faculty of Medicine North, with the aim to offer a credible alternative to conventional surgery.

Thus the investigators propose to conduct a pilot prospective intervenionnal study. The investigators hypothetized that this technique would reduce morbidity and mortality clinical but also economic consequences of surgery while making it possible to obtain excellent results permeability and long-term functionality. This method uses a new concept of tissue apposition with a fully covered metallic stent to create the anastomosis under endoscopy exclusively. Ten patients with antro duodenal obstructions requiring surgical or endoscopic bypass will be included as part of an interventional biomedical research that will be conducted in one expert center. The duration of the inclusions will be 18 months. Then, the stent will be removed three months after insertion, at the end of the healing process, and each patient will be followed for one year. The primary endpoint will be the assessment of the feasibility of the procedure for gastro duodenal anastomosis using tissue apposition stenting and NOTES in human being. The secondary endpoints will be the clinical efficacy, the long term (1 year) patency of the anastomosis, the procedure duration, adverse events, morbidity and mortality, the quality of life and the length of stay.

In case of failure of the NOTES procedure, the patient will be treated either by surgery or by conventional endoscopy according to the usual techniques without loss of chance. The risk / benefit ratio appears positive and a safety report will be issued after the first 4 inclusions. There will be no supplementary examination in patient follow-up in this study for which a CT iconography and biology are enough. The material used in the context of this work is consistent with the legislation on medical devices and has received CE Mark (tissue apposition fully covered stent Axios ®).

acronym: CAR-DIFF

summary:
An injury of haematosis in post ischemic chronic heart failure limits the clinic tolerance.

There is a correlation between injury of pulmonary diffusing, chronic heart failure intensity and aerobic physic ability evaluated by an heart-rate maximal exercise tolerance test (VO2 max). This injury is a new follow-up parameter of cardiac function for the adult.

The nature of damage (vascular or membrane) can be determined by the measure of double pulmonary diffusing capacity to carbon monoxide (CO) associated to nitric oxide (NO).

Today, in chronic heart failure consecutive to a congenital heart disease, there is no data on evolution of membrane and capillar factors.It is impossible to predict if membrane damage will be the best factor correlated to the VO2max in patients suffering from complex congenital heart disease.

Assessing these parameters could be an comparative evaluation of heart-rate exercise tolerance test with VO2max and an early control of his damage without risks related to heart-rate maximal exercise and independently of age, sex, hemoglobin, type of heart disease.These results would have an early prognostic value that would permit to refine the follow-up and the treatment.

The main objective of this trial is to assess the statistic correlation between the membrane injury of alveolar-capillary diffusing at rest and aerobic physic ability restriction in children and adults suffering from complex congenital heart disease.

title: Toxicity of Perirenal Fat in Overweight or Obese Subjects: A Pathophysiological Link Between Uric Acid Stones and Renal Ammonium Formation

summary:
Patients who are overweight or obese, diabetic or not, share with those who are suffering from uric stones the same way to remove abnormal acidity of the body in urine, ie a kidney ammoniogenesis default. This results in an overly acidic urine pH which is directly pathogenic in people predisposed to develop uric stones because the precipitation of urate soluble uric acid is accelerated in acid medium.

Excess visceral fat, particularly perirenal, this defect may promote formation of renal ammonium. Indeed, the perirenal fat is adjacent to the renal cortex and shares with it a common arterial supply via the plexus Turner. Adipokines and fatty acids of the perirenal fat are predisposed to gain the renal cortex, seat of the ammoniogenesis. In humans the pathogenic role of the perirenal fat is demonstrated in chronic kidney disease and essential hypertension. However, the amount of fat and perirenal that of intra-abdominal fat are positively correlated.

Investigators hypothesis is that the perirenal fat also exert a pathogenic role in uric because of anatomical links between kidney stones and greasy environment and because excess fatty acids reaching the renal cortex decreases ammoniogenesis in an animal model metabolic syndrome.

For the test, the investigators will compare the amount of fat and perirenal renal ability to form ammonium in patients with uric or calcium lithiasis taking into account the amount of intra-abdominal fat.

title: Cognitive Training in Children With Attention Deficit Hyperactivity Disorder (ADHD)

summary:
ADHD is associated with cognitive deficit. Therefore, cognitive training is often proposed as an intervention for ADHD that targets cognitive deficits, with specific exercises through intensive training sessions. This intervention is based on principles of brain plasticity and cerebral functional reorganizations.

Working memory deficits constitute a key impairment in ADHD. That is why, Cogmed working memory training is the most commonly used and studied cognitive training program in clinical practice and research. It is clear from most studies that Cogmed training program increases working memory in ADHD. However, transfer of learning is not demonstrated on: other cognitive functions that are not targeted by the program, on ADHD symptoms, nor on academic achievement.

In addition to this type of intervention multi-factorial program targeting different cognitive function as Presco also exist but have been less studied.

To address these challenges, this study will follow a randomized and controlled design.

The main objective of this study is to examine the impact of cognitive training in comparison with a control waiting-list group among children with ADHD on:

ADHD symptoms,
cognitive functioning,
attentional capacities
academic achievement.

The second objective is to compare two types of cognitive training a unifactorial program Cogmed targeting working memory and a multifactorial Presco focusing on different cognitive functions affected by ADHD.

Long-term effects are examined six months after training. Participants (n=90) will be randomly assigned to the two experimental group (Cogmed or Presco) or to the control group waiting list. Participants will be evaluated three time (time 1) just before the intervention, (time 2) six weeks after the first evaluation, immediately after the intervention and (time 3) six months after the intervention.

title: Identification and Quantification of a Mechanical Hyper-synchronicity State in Hypertrophic Cardiomyopathy (HCM) With Left Outflow-tract Obstruction and Description of Its Electrical and Electro-mechanical Characteristics Thanks to an Innovative Multi-imaging Approach to Predict a Positive Response to Dual Chamber Pacing. The Hsync Study.

acronym: HSYNC

summary:
Hypertrophic cardiomyopathy (HCM) is a common genetic cardiovascular disease. Outflow-tract gradient of 30 mmHg or more under resting conditions is an independent determinant of symptoms of progressive heart failure and death.

The investigators hypothesize that the electrical approach by dual chamber pacing could improve symptoms and reduce outflow-tract obstruction in a specific sub-group of selected patients with a mechanical hyper-synchronicity. The aim of the study is to identify and describe this phenomenon in HCM with (O-HCM) and without (NO-HCM) outflow-tract obstruction thanks to innovative multi-imaging approach.


title: Efficacy of Deep Transcranial Magnetic Stimulation (TMS) for Treatment-resistant Depression and Neuroanatomical Correlates: a Randomized Clinical Study Coupled With Positon Emission Tomography (PET)

summary:
Repetitive transcranial magnetic stimulation (TMS) is an emergent non-invasive treatment for treatment resistant depression (TRD). The exact neuro-functional mechanisms related to TMS efficiency remains however unknown; besides local effect on the target, TMS may induce interaction changes between remote cerebral regions. On the other hand, few studies have been performed in comparison to sham placebo stimulation. The investigators recently showed that non-responder depressive patients to TMS exhibited deeper and wider brain functional abnormalities hardly reachable by standard coils. The H1-Coil is a novel TMS (H-TMS) device capable of inducing a magnetic field with a deeper and wider distribution than standard coils.

The investigators design here a randomized controlled study in which the investigators will compare the clinical effects of H-coil TMS and standard TMS in patients with TRD, and their functional neuroanatomical correlates and changes in connectivity by Positron Emission Tomography (PET). The general objective is to better understand the mechanisms related to TMS efficiency in pharmacoresistant depression, in order to propose the best therapeutic approach for the patient.

title: Subcutaneous Injection of Autologous Adipose Tissue-derived Stromal Vascular Fraction Into the Fingers of Patients With Systemic Sclerosis : Controlled Clinical Trial With Efficacy Assessment

summary:
Systemic sclerosis (SSc) is an auto-immune orphan disease mainly characterized by an alteration of the microvascular network, and by cutaneous and visceral fibrosis. Hands are frequently affected, as a consequence of ischemic phenomena and cutaneous fibrosis.

. The injection of adipose autologous tissue is a common practice in plastic surgery, and has been known for over a century. Adipose tissue, originally used to increase volume, is also characterized by trophic properties associated to stromal vascular fraction (SVF), which contain multipotent stem cells, capable of tissue repair. Interestingly, some SVF cells can be angiogenic and anti-inflammatory, which could improve damage seen with SSc.

A prior study (the SCLERADEC protocol: ClinicalTrials.gov NCT01813279) has already allowed the safety and tolerance at 6 months of the subcutaneous injection of SVF in the fingers of twelve patients to be proven.

The encouraging results have encouraged us to propose a trial which would bear on a higher number of patients and include a control group.

title: Clinical and Medico-economic Evaluation of Radiofrequency Ablation Versus Oesophagectomy in the Treatment of High Grade Dysplasia in Barrett's Oesophagus

acronym: HARMONI

summary:
First intent treatment for superficial circular esophageal neoplasm is surgical resection. Endoscopic mucosal resection is not recommended due to the high rate of subsequent esophageal stenosis (higher than 80%).

Surgical limits are related to a high level of morbidity due, in particular, to respiratory complications or infections that require prolonged hospitalisations, and by significant rate of mortality (from 2 to 5 %). As an alternative to the surgical treatment, an innovative technique to remove esophageal circular preneoplastic and neoplastic lesions has been developed: it consists to ablate the mucosa by means of a balloon of a fixed diameter which incorporates approximately 100 electrodes on its surface that emit radiofrequency waves (HALO® Radiofrequency Ablation Technology System). By varying the strength and the duration of the electrical impulses, it is possible to obtain a homogenous and controlled destruction of the tissue of the whole mucosa, leaving no remaining pre-neoplastic or neoplastic elements underneath. The technique will be used for high grade glandular epithelial neoplasia, Vienna 4-1 or 4-2, developed on a mucosa at risk, i.e. the Barrett's oesophagus, occupying more than half of the circumference of the esophagus and that requires surgical treatment. The expected benefit for the patient is linked to the reduced invasiveness of the technique in comparison to the surgery

title: Evaluation of an Algorithm for Identifying Persistent Nasal Staphylococcus Aureus Carriage in a Cohort of Healthy Volunteers and Patients Regularly Monitored at the CHU of Saint-Etienne

acronym: ScreenStaph

summary:
The nasal carriage of Staphylococcus aureus is a major risk factor of S. aureus infection, notably in hemodialysis patients (HPs). Decolonization strategies were shown able to reduce the rate of S. aureus infection in this category of patients although the risk of emergence of antimicrobial resistance persists. Approximately one quarter of the general population is colonized by S. aureus in the anterior part of the nostril (vestibulum nasi). Three main categories of nasal carriers have been historically identified: persistent carriers (20%, 12-30%]), intermittent carriers (30%, [16-70%]) and non-carriers (50% [16-69%]). By contrast to intermittent carriers and non-carriers, persistent nasal carriers have a higher risk of S. aureus infection, especially in continuous peritoneal dialysis and in orthopedic surgery.

Persistent carriers are characterized by a higher nasal bacterial load, a longer duration of carriage, a lower rate of exchange of S. aureus strains, and a particular affinity for the carried strain. However, there is no consensual definition of this persistent carriage state. In previous studies, 5 to 12 nasal sampling episodes were realized for a period ranging from 5 weeks to 8 years. The index of carriage, corresponding to the number of samples positive for S. aureus divided by the total number of samples, has been proposed to standardize the definition of the carriage state. According to standard tools, it is almost impossible to determine the nasal carriage state in routine practice.

Recently, an algorithm based on one or two quantitative cultures from nasal samples taken within 2 days that was able to distinguish accurately persistent and non-persistent nasal carriers of S. aureus has been described; only one nasal sample was needed in more than 9 cases out of 10. The aim of the present study was to assess prospectively the reliability of this algorithm in clinical practice in a cohort of healthcare workers (HCWs) and HPs and to check its ability for identifying patients with the highest risk of S. aureus infection

title: Impact of Two Standardized Clinical Care Protocols on Pregnancy Outcomes in Women With Monogenic Diabetes MODY2

summary:
Maturity-onset diabetes of youth (MODY) are the most frequent monogenic diabetes with autosomic dominant inheritance (2% of diabetes). The MODY2 diabetes is related to a defect in the glucokinase (GCK) enzyme, the first limiting step of insulin secretion. An abnormal GCK leads to a delayed insulin secretion. Patients with GCK mutations have only mild raised fasting plasma glucose. Treatment is usually unnecessary since hyperglycemia is stable and MODY2 patients have no microvascular complications of diabetes. In contrast, pregnancy in MODY2 women is a challenging situation. A non-mutated fetus will produce excess insulin in response to raised maternal blood glucose leading to an accelerated growth and a higher risk of macrosomia. The mother of non-mutated fetus should therefore be treated to normalize her blood glucose levels. On contrary, a mutated fetus will produce a delayed insulin secretion (as his MODY2 mother) in response to maternal hyperglycemia. Consequently insulin therapy during pregnancy would reduce fetal insulin secretion and result in a low birth weight.

Moreover, insulin therapy exposes pregnant women to more labor induction, prematurity and cesarean deliveries. In these MODY2 women whose glucose set point is physiologically higher, glycemic goals are difficult to achieve while often requiring extensive insulin therapy. An optimal situation would consist in initiating insulin therapy only for women with non-mutated offsprings. Unfortunately no antenatal diagnosis of the GCK mutation on fetal cells is available yet. In literature, birth weight differences between mutated and non-mutated neonates may reach up to 700g. In clinical practice, two strategies are used but without standardized protocol on glycemic targets, delay and doses of insulin : 1) insulin at diagnosis of pregnancy 2) treatment based on fetal abdominal circumference and fetal weight measurements by ultrasonography (US) and initiated if fetal biometry is greater than the 75th percentile.

The purpose of the study is to evaluate for the first time these two management strategies through a prospective and standardized study. Hypothesis: US assessment would be sufficient to identify fetuses at risk of macrosomia and to initiate insulin treatment in mothers.

title: In Vivo Endomicroscopic Description of Pulmonary Microcirculation in Systemic Sclerosis and Emphysema Patients

acronym: MiPECSE

summary:
Systemic sclerosis (SSc) is a generalized disorder of connective tissue, arterioles and microvessels, characterized by the occurrence of fibrosis and vascular obliteration phenomena. The alterations in lung microvessels are found in pulmonary involvement of scleroderma, which are the most serious complications of the disease.

In pulmonary emphysema, there are also changes in pulmonary microvasculature, which are involved in the onset and development of the disease.

The confocal endomicroscopy is an endoscopic technique which can be performed during a bronchoscopy. This technique makes it possible to observe in real time the most distal pulmonary elements at the microscopic scale. After injection of fluorescein, then the technique of observing the pulmonary microvasculature, in vivo and in situ.

The characterization of microvascular lesions in these two pathologies could improve understanding of their mechanisms and ultimately improve the early management of patients.

title: Consequences of DNA Repair and Telomere Defects on the Function of the Immune System: Application to CVID and Immune Deficiencies With Dysmorphic Syndromes

acronym: IMMUNEREP

summary:
The molecular mechanisms participating in the various aspects of the DNA Damage Response (DDR) are absolutely essential to maintain the genome dynamics essential to all living organisms. The most commonly studied consequence of faulty DDR is genome instability participating in cancer onset. In the present proposal, we wish to explore another aspect of DDR, not relevant to cancer, which is its absolute requirement at several key steps of the development, maturation, and function of the immune system.

The most "spectacular" consequences of faulty DNA repair processes with respect to the immuno-hematopoietic tissue are the complete block of B and T lymphocytes maturation owing to defective DNA joining phase during V(D)J recombination resulting in patients with Severe Combined Immune Deficiency (SCID).

The objectives of this study are to increase our knowledge on the role of the various DNA repair processes in the development, the maintenance, and the function of the immune system and thus, to better understand why and how dysfunctions of these DNA repair processes result in human severe conditions such as CVID, LOCID or other manifestations of immune disorders such as autoimmunity.

The explorations of DNA repair mechanisms in the patients will allow us to establish the genetic diagnosis in some patients with until now undefined molecular diagnosis. This is of immediate importance for the patients and their families, as it not only contributes to a better understanding of the patients' condition, but also allows providing genetic counseling for the families.

title: PROGNOSTIC VALUE OF CIRCULATING TUMORAL FREE DNA Versus CIRCULATING TUMORAL CELLS IN PATIENTS WITH COLORECTAL CANCER STAGE II-III

acronym: CTC

summary:
After curative surgical resection, detection of metastatic lymph node remains the main prognostic validated criteria on which is based the decision of adjuvant therapy. To date, none of the molecular alterations, identified as potentially predictive factor, are used in routine for therapeutic decision. The circulating markers, either in the form of free circulating DNA or in the form of circulating tumoral cells seems important potential candidates. To investigators knowledge, only one study estimated with several interesting results the prognostic interest of a coupled detection of the free circulating mutant DNA (gene KRAS) and by the hypermethylation of the p16 gene. Definitive conclusions remain however difficult to achieve because of the small number of patient included (n=58) and the fact that this study included different stages. For colorectal cancer a Chinese team presented a series of results suggesting that the presence of CTC during the postoperative course is a factor significantly related to the risk of recurrence. In multivariate analysis integrating the lymph node status and the vascular invasion, the presence of CTC appeared as an independent factor for recurrence with a hazard ratio of 29.5.

The aim of the present study is to compare the prognostic value of two circulating tumoral markers KRAS point mutations and RASSF2A methylation (free tumoral DNA) and Circulating tumoral cells (CTC). The primary objective is to compare sensibility and specificity of two circulating markers (free tumoral DNA and tumoral cells) on 2 years disease free survival rate. Secondary objective is to confirm the prognostic value of circulating free tumoral DNA and circulating tumoral cells in localised colorectal cancer.

summary:
Inflammatory choroidal neovascularization (InCNV) is the third cause of CNV after myopia and Age-related Macular Degeneration (AMD). InCNV is a rare but severe disease and its treatment should not be delayed.

InCNV is treated at the moment with off-label anti-VEGF (Vascular Endothelial Growth Factor) therapy and could also benefit from aflibercept (EYLEA), a new anti-VEGF currently indicated in AMD. Case reports suggest that such patients would not need as many injections as in AMD.

ALINEA is an open-label, single arm, prospective, multicenter, phase II study. The main objective is to demonstrate the effectiveness in clinical terms after 52 weeks of treatment with aflibercept on the visual acuity of patients affected by InCNV. A specific dosage regimen is designed to achieve maximum efficiency. The patients are followed on a monthly basis until 52 weeks. The first injection is mandatory. The other ones are injected only in case of active InCNV.

title: Role of Epoxyeicosatrienoic Acids in Chronic Allograft Nephropathy

acronym: TRANSPLANTEETs

summary:
Endothelial lesions within the transplanted kidney are a major determinant of chronic allograft nephropathy. Epoxyeicosatrienoic acids (EETs) are endothelium-derived hyperpolarizing factors with anti-inflammatory, antiproliferative and vasodilator properties.

The main goal of the investigators' study is to evaluate whether genetic polymorphisms of specific enzymes responsible for the bioavailability of EETs are associated with post-transplant kidney function.

To this end, 80 kidney transplant recipients will be included. Prespecified genetic polymorphisms of CYP 2J2, CYP 2C8, CYP 2C9, CYP 2C9, CYP 2C19 and EPHX2 will be determined. Kidney function will be recorded 3, 6, 12 and 36 months after transplantation. Flow-mediated dilatation, EETs and circulating biomarkers of endothelial function will be measured in the radial artery.

The expected results of this study to provide preliminary evidence supporting a beneficial role of an increase in the bioavailability of EETs in kidney transplant recipients.

title: Phase IA/IB of Metronomic Chemotherapy Based on Adaptative Bio-mathematical Model of Oral Vinorelbine in Patients With Non Small Cell Lung Cancer or Malignant Pleural Mesothelioma

acronym: NVB Metro

summary:
Background: Metronomic oral Vinorelbine has efficacy in metastatic NSCLC and malignant Pleural Mesothelioma, but all the studies published thus far were based upon a variety of empirical and possibly suboptimal schedules, with inconsistent results. Mathematical modeling showed by simulation that a new metronomic protocol could lead to a better safety and efficacy profile.

Design: This phase Ia/Ib trial was designed to confirm safety (phase Ia) and evaluate efficacy (phase Ib) of a new metronomic oral vinorelbine schedule. Patient with metastatic NSCLC or malignant Pleural Mesothelioma, after failure of standard treatments, ECOG 0-2 and an adequate organ functions, will be eligible. Our mathematical PK-PD model suggested an alternative weekly D1, D2 and D4 innovative schedule (named Vinorelbine Theoretical Protocol) with a dynamic intake of 60, 30 and 60 mg, respectively. Trial recruitment is two-staged as 12 patients are planned to participate in the phase Ia, to confirm safety and consolidate the calibration of the average parameters of the model. Depending the phase Ia result, and after favorable decision of a consultative committee, the extension phase (phase Ib) will be an efficacy study and will include a number of 20 patients receiving the Optimal Vinorelbine Theoretical Protocol. The primary endpoint is the tolerance (assessed by CTC v4.0) for the phase Ia and the objective response according to RECIST 1.1 for the phase Ib.

An ancillary study on circulating angiogenesis biomarkers will be a subproject of the trial.

Discussion: this ongoing trial is the first to prospectively test a mathematical optimized schedule in metronomic chemotherapy. As such, this trial can be considered as a proof-of-concept study demonstrating the feasibility to run a computational-driven protocol to ensure an optimal efficacy/toxicity balance in patients with cancer.

title: Psychoeducational Programme for Patients With Parkinson's Disease Undergoing Subthalamic Deep Brain Stimulation

acronym: PSYCHE

summary: Bilateral subthalamic deep-brain stimulation is a well-established therapeutic option to improve motor signs and reduce dopaminergic treatment and related motor complications in patients with severe forms of Parkinson's disease (PD). However, psychological disorders and socio-familial maladjustment are less clearly improved with subthalamic stimulation with an aggravation of the social adjustment described in about 1/3 of cases, with work disruption, divorce or familial conflict. The caregivers have also been reported to present negative well-being after surgery with an aggravation of the quality of life. In the present study, the investigators evaluate the effects of a perioperative psychoeducational programme to avoid postoperative socio-familial maladjustment in PD patients candidate for subthalamic stimulation, and their caregivers, in a randomized controlled study.


title: Recherche et Mesure d'Anomalies précoces de la Marche au Cours Des Troubles du Comportement en Sommeil Paradoxal Idiopathiques

summary:
Many people with idiopathic rapid eye movement (REM) sleep behavior disorder (RBD) have an underlying synucleinopathy, the most common of which are Parkinson's disease (PD) and Lewy body disease. Identifying additional abnormal clinical features may help in identifying those at greater risk of evolving to a more severe syndrome. Because gait disorders are common in the synucleinopathies, early abnormalities in gait in those with RBD could help in identifying those at increased risk of developing overt parkinsonism and/or cognitive impairment.

The investigators aim to identify subtle gait abnormalities in idiopathic RBD and to identify sensitive and early biomarkers:

to detect subtle gait disorders in pre-symptomatic stage of synucleinopathy and
to track their evolution in the parallel with the disease progression.

Main objective: In comparison with age and gender matched-controls, to identify in patients with RBD a larger reduction of gait velocity (and other abnormalities of spatio-temporal characteristics of gait) between a single (gait) and a dual-task (gait+cognitive task).

Secondary objective:

In comparison with age and gender matched-PD patients, to identify in patients with RBD a smaller reduction of gait velocity (and other abnormalities of spatio-temporal characteristics of gait) between a single (gait) and a dual-task (gait+cognitive task).
In patients with RBD to identify correlations between the spatio-temporal characteristics modifications of gait between a single (gait) and a dual-task (gait+cognitive task) and the percentage of REM without atonia - the dopamine transporter (DAT) density using FP-CIT single-photon emission computed tomography; the reduction of the olfactory discrimination and thresholds.
In patients with RBD to track the spatio-temporal characteristics evolution of gait over time (every 6 months for 2 years)

title: Breast Reconstruction and Body Map : Assessment by Functional MRI (REMASCO)

acronym: REMASCO

summary:
Breast reconstruction is an integral part of the management of patients with breast cancer and treated by total mastectomy. The aim of breast reconstruction is to get a satisfying aesthetic and functional result (sensitivity) and that would enable the patient to appropriate the reconstructed breast. Patient satisfaction assessed subjectively by questionnaires would be better in autologous reconstructions than in reconstructions by prosthesis.

The aim of our trial is to use functional MRI (fMRI) as an objective evaluation tool to describe the brain functional changes of sensory projections after immediate or secondary breast reconstruction.

title: Molecular Mechanisms of Senescence Predisposing to Cancer : Exploratory Analysis on Healthy Tissues Collected for Two Age Groups.

summary:
Epidemiological data show that the incidence of carcinoma, the most common cancer, is strongly linked to the age. Non Melanoma Skin Carcinomas (NMSCs) (the most frequent cancers in the elderly population) derive from keratinocytes of the basal layer of the epidermis, from differentiated keratinocytes of the more superficial layers or from stem cells of hair follicles. Unlike NMSCs, soft-tissue sarcomas, including those deriving from dermal fibroblasts, are very rare (less than 1% of all cancers). Our overall purpose is to decipher the molecular pathways activated during the aging of these tissues that may explain why they have a so different propensity to undergo a malignant transformation. Given that senescent cells accumulate in the dermis and epidermis with age, we will constitute two groups : "young skin" that we arbitrarily limit to the range ≥ 18 and ≤ 40 and "aged skin" ≥ 55.

Thus the main objective of our study is to search within 2 age groups (≥ 18 and ≤ 40 years and ≥ 55 years) the expression of senescence markers on healthy skin tissue.

title: Analysis of Swallowing, Speech and Quality of Life of Patients With Stage T3-T4 Squamous Cell Carcinoma of the Oropharynx Before and After Multimodal Treatment With Curative Intent

summary:
The curative treatment and organ preservation in advanced squamous cell carcinoma of the oropharynx is multimodal. It involves induction chemotherapy and depending on the response radio-chemotherapy or surgery. The combination of these methods has important functional consequences.

The aim of this prospective pilot study is to describe swallowing, speech, but also patients' quality of life before and after therapeutic management (existing studies measuring these functions after treatment but not before).


title: Study of the Effect of an Active rTMS Session in Pathological Gamblers: Impact on Craving and Severity of These Behaviors

summary:
The gambling problem is characterized by a loss of control and an excessive focus on the gambling practice. Currently, the treatment of pathological gamblers is often complex and multidimensional, it notably includes psychological techniques including cognitive behavioral therapy and the use of psychotropic drugs.

In pathological gambling and addictions, craving (or urge to play) and loss of control are two essential clinical elements. The neurobiological level, they are associated with a dysfunction of dorsolateral prefrontal cortex (DLPFC) (Goldstein et al, 2001, Volkow and Goldstein, 2002).

One therapeutic avenues explored in addictions is repeated transcranial magnetic stimulation (rTMS).

title: Assessment of the Intraoperative Probe-based Confocal Laser Endomicroscopy in Digestive and Endocrine Surgery - a Pilot Study

acronym: Pilot pCLE

summary: Intraoperative histological examination is a fundamental tool in surgery. Probe-based Confocal Laser Endomicroscopy (pCLE) is a new imaging technique which enables real-time, microscope-resolution imaging, currently used in endoscopy. This pilot study aims to evaluate pCLE in surgical setting. The objective is the depiction of histological rendering of normal and pathological tissues through pCLE. Feasibility of real-time diagnosis will also be assessed. All surgical conditions usually necessitating frozen section will be investigated. A total of 30 patients, with various pathology of the thyroid / parathyroid, stomach, esophagus, pancreas, adrenal, colon / small intestine, liver will be included. Diagnostic criteria will be defined by a surgeon - pathologist team and further validated by retrospective analysis of the video sequences in comparison to conventional histology slides. The data will be used to create an image bank of reference optical biopsy images. The study will allow to point out the surgical conditions in which pCLE is the most effective and reliable and could eventually replace the frozen section technique.

title: Contribution of Near-InfraRed Spectroscopy (NIRS) to the Evaluation of Microcirculation Following Trans-tibial Amputation for Peripheral Artery Disease

acronym: NIRS

summary:
50 patients will be included for each of the 2 procedures:

- For procedure 1: Patients will be selected during multidisciplinary consultations for amputees who are stabilized with their definitive prosthesis and have returned to their usual place of residence. The aim of this procedure is to show the validity and reproducibility of measurements of tissue oxygenation using NIRS (TcPO2 being the reference measurement), to determine the way in which NIRS measurements are more precise (i.e. in terms of validity and reproductibility) (values at rest with the patient lying perfectly flat or with the amputated limb raised 30°). These patients will require a single visit which will include measurements by NIRS and TCPO2, a walk test and the completion of 2 questionnaires (visual scale).

- For procedure 2: The patients will be included in the initial phase of postamputation rehabilitation, during the period of in-hospital rehabilitation. The main problems of healing and tolerance to the temporary prosthesis arise during this phase. The specific objectives will be: To show that measurement by NIRS predicts the quality of healing in trans-tibial amputees; to show that the zone of uncertainty concerning the predictive values for the viability of the stump is smaller with NIRS than with TcPO2 (better discrimination). NIRS and TCPO2 measurements as well as the evaluation of stump healing will be done 15, 30 and 45 days after the amputation.

title: Estimation of Pain During Epidural Analgesia During Labor - a Monocentric Study

acronym: PERIDANS

summary:
Epidural regional anesthesia is a technique to eliminate or lessen pain during obstetric labor and childbirth. It consists in establishing a catheter into the epidural space and to block the transmission of pain sensations by injecting a local anesthetic and an opioid. In 10-25% of cases the epidural does not give perfect results, causing it to test its effectiveness, which is mainly done by questioning the patient on mitigation or disappearance of pain. This collaboration of patients is sometimes limited in our care structure by the inability to assess or express the pain, mainly due to cultural differences or language barriers, which can represent up to 15% of women in our institution. This led to develop objective measures of pain techniques used at the bedside.

Pupil diameter (PD) varies under the double influence of sympathetic system (Σ), dilator of the pupil, and parasympathetic system (pΣ).

The PD increases in response to painful stimulation, in proportion to the intensity of the nociceptive stimulus. This variation of PD has been proposed as a means of evaluation of pain in patients under general anesthesia, but has been little studied in conscious subjects.

There are other permanent changes in the PD, due to constant interaction between Σ and pΣ systems. Few data have been published to date on this PD variability (PDV).


title: Association Between Circulating Immune Cells and the Tumor Immune Contexture in Resectable Non-small Cell Lung Cancer

acronym: LYMPHOLUNG

summary: With the recent approval of Nivolumab for second-line treatment of stage IIIb/IV non-small cell lung cancer (NSCLC), immune checkpoint inhibitors are entering the standard of care for lung cancer. Other immune checkpoint inhibitors are under evaluation, both in resectable and non-resectable NSCLC. In order to refine our use of these molecules, comprehensive data on the immune contexture of NSCLC are needed. Moreover,a blood marker of this contexture would allow physicians to monitor the immune status of their patient's tumor and though to evaluate the rightful place of immunotherapy in the multimodal treatment of NSCLC. No such blood marker has been validated so far. The LYMPHOLUNG study investigate the concordance between blood and intratumoral counts of immune cells in resectable stage I to IIIA NSCLC. By the use of 30-marker cytometry, a precise immune profile of NSCLC will be depicted. The prognostic value of the circulating and intra-tumoral T regulator over total lymphocytes ratio for 2-year recurrence-free survival will also be addressed.

acronym: COSIMH

summary: Huntington's disease is a rare genetic neurodegenerative disease. It is accompanied by movement disorders, cognitive and behavioral. The social behavior of patients are changed, affecting interpersonal relationships. Patients with Huntington's disease are described as self-centered, lacking sympathy and empathy and mentally inflexible. These behavioral problems can be a major source of anxiety for patients and their families. These disorders also have a negative impact cognitive and motor symptoms as well as the functional abilities and the quality of life of patients and their entourage. Authors have suggested that these problems could be related inter alia to social cognition disorders. This concept refers to a set of skills and emotional and social experiences that regulate relations between individuals and can explain the behavior of individuals and groups. The objective is to evaluate disorders of social cognition, which may account for behavioral changes in Huntington's disease.

title: Evaluation of the Reproducibility of the Measurement by 2D Ultrasound and Sonoelastometry of the Pennation Angle and Elasticity of the Medial Gastrocnemius Muscle in Children/Adolescent/Adult Cerebral Hemiplegia After Stroke

summary: Hemiplegic adults after stroke (stroke), children and adolescents with cerebral palsy (CP) have both muscles spastic and paresis. These movement disorders are likely to cause muscle changes both structural and viscoelastic involved in the alteration of neuromotor functions such as walking. Therefore, it seems interesting to study the structure of these muscles with available imaging techniques. The medial gastrocnemius muscle presents architectural characteristics which allows easy evaluation 2D ultrasound. The literature lacks data on the reproducibility of the measurement, by 2D ultrasound, of the pennation angle and muscular thickness, particularly in children. In addition, the sonoelastometry by Supersonic ShearWave Imaging (SSI) is a new technique of ultrasound, non-invasive, dynamic, which allows the calculation of the modulus of elasticity within a muscle tissue. This allows to consider new perspectives evaluation of the viscoelastic properties of the muscle. No studies have evaluated the reproducibility of this method in adults/children/ adolescent after stroke and hemiplegia.

title: Study of the Impact of Changes in Carbonemia on Microcirculation in Patients - A Monocentric Study

summary:
The microcirculatory alterations is common in circulatory failure, especially during sepsis. The severity of these changes and their sustainability are responsible of multi organ failure and ultimately death. The optimization of microcirculatory flow could be a central objective of the management of patients hospitalized in intensive care.

Microcirculation includes all blood vessels of a diameter smaller than 100 micrometer. It represents the largest heat exchange surface of the body and is involved in tissue oxygenation. Microcirculatory flow is conditioned by the macrocirculation (heart rate and blood pressure) and the state of the microcirculation (thrombosis, vasoconstriction ...). The role of the CO2 in regulating microcirculatory flow is little studied. A recent work of our team and the oldest work in the literature lead to believe that CO2 has a specific role in modulating microcirculatory flow. No study to date precisely studied the impact of changes in the microcirculatory flow carbonemia .

The hypocapnia test is carried out in a standardized manner by inhalation of a mixture enriched in CO2 7% allows a significant increase in carbonemia. Hypocapnia will in turn obtained by a calibrated voluntary hyperventilation test.

Direct visualization of microcirculation by confocal microscopy is now considered the gold standard for exploring the microcirculation.


title: Study of the Effect of the Position of the Patient's Head With Brain Lesions on Cerebral Blood Flow

summary: The position of the head of the patient influences the cerebral venous return and cerebral perfusion pressure (CPP). In our daily practice, it is almost routine to prescribe a Trendelenburg position 30 ° in all brain-damaged patients. However, this is based only on precarious bibliographic databases. It has been shown to decrease the Intracranial Pressure (ICP) in Trendelenburg position relative to the horizontal, with varying effects on PPC. Effects on sylvian objectified by Doppler velocities and cerebral oxygenation seem unaffected by changes of position of the head of the patient. But the whole of the literature on this subject has significant bias.


title: Effectiveness of Active Home Exercises for Patients With Chronic Neck Pain: a Prospective Comparative Randomized Clinical Trial

summary:
The prevalence of non-specific neck pain is 12.1 / 1000 patients / year. Their support is most often based on analgesics combined with physical therapy. More recently authors have advocated the use of self-rehabilitation, that is to say, the use by the patient himself of physiotherapy exercises to perform at home regularly. However, if there are currently many studies on the effectiveness of self-rehabilitation for low back pain, there are few data on neck pain.

In this context we have chosen to implement a prospective, randomized study, on the effectiveness of self-rehabilitation in patients with chronic neck pain.
