title: Genome Study in Constitutional Thinness

acronym: GENOSCANN

summary:
Constitutional thinness (CT) is a recently defined entity as a differential diagnosis of anorexia nervosa (AN), considered to be the most frequent cause of low body mass index (BMI) in young women. CT subjects present no AN psychiatric traits, preserved menses, no biological signs of undernutrition and balanced energy metabolism despite a Body Mass Index (BMI) <17 kg / m².

CT familial aggregation, low body mass without a hormonal explanation, and specific appetite regulation profile suggest a specific genetic profile in these subjects.

Objective: A family linkage study in order to identify genes involved in the constitutional thinness phenotype by using genome wide scan (GWAS) techniques Studied population: Fifty families including at least one well phenotyped CT index case (grade 2 or 3 of thinness according WHO classification). Blood or saliva is sampled for DNA extraction.

Perspectives: Revealing eventual abnormalities could lead to a more precise diagnosis of constitutional thinness and new hypothesis in understanding extreme bodyweight mechanisms.


acronym: TMS HALLU

summary:
Auditory hallucinations are common (present in 60-70% of cases) and extremely debilitating. Behavioral disorders associated with them can have serious social repercussions. However, in 25% of cases the usual antipsychotic drug treatments are incompletely or totally ineffective.

Fifteen subjects will be included after collection and signed their informed consent.

The rTMS treatment is made of 4 sessions of 13 minutes spread over two days, at a frequency of 20 Hz and an intensity of 80% of motor threshold at rest. These constants are used to stay below the risk of occurrence of seizures, the only serious side effects identified. Furthermore the rTMS treatment is almost painless: tension headaches are the main side effects and make amends with simple analgesics. rTMS is devoid of neurocognitive effects. The LEFT stimulation site will be established through a anatomofunctional imaging before treatment (between D-7 and D0).

Treatment efficacy will be evaluated daily during treatment (days 1 and 2) and during the first 2 weeks of starting treatment.

title: Pilot Study Immunomonitoring NK Cells in Patients With Myeloid Malignancies

summary:
This project is a framework for developing new therapeutic strategies for acute myeloid leukemia(AML)based immunotherapy.

the role of NK cells was demonstrated in AML and especially GVL effect (graft versus leukemia) during allogeneic transplantation in these patients. However, it has been shown that the phenotype of NK cells and their cytotoxic functions were altered during this malignancy. In addition, in these patients, impaired NK function is associated with relapse.

lenalidomide it would have a beneficial effect on NK cells of AML patients? Does it have a role in leukemic cells in this malignancy? what is its effect on the production of pro-inflammatory cytokines? In vitro data show an effect of lenalidomide on the phenotype of NK cells from healthy donors and patients with LAM, and despite these phenotypic changes, the cytotoxic capacity of NK is not altered.Lenalidomide also induces a significant increase in the production of TNF-alpha (tumor necrosis factor) by NK.

It also seems to have an effect on leukemic blasts of AML. So, the investigators hope this study confirm these results in vivo in peripheral blood cells in patients treated with lenalidomide.

title: Double-blind Randomized Prospective Phase III Study of a Continues Cicatricial Perfusion of Ropivacaine Versus Placebo After Mastectomy : Rehabilitation After Treatment of the Postoperative Pain From Hospital to Home

summary:
The acute pain care, in particular after breast cancer surgery must be early and quickly effective, because a severe postoperative pain increases the risk of chronic pain and exposes to a risk of important embarrassment for the realization of simple daily movements.

Associated to conventional analgesics administered by systemic way, a local anesthesic (ropivacaine) can be continuously infused (Continues Cicatricial Perfusion CCP) in the operating wound by a multi-drilled catheter by means of a elastomeric diffuser set up in the surgical unit by the surgeon at the end the surgical procedure.

Besides the control of the postoperative acute pain, the local anesthesic could intervene in the prevention of the chronic pain, the early recovery, the reduction of the neuropathic pains and the decrease of needs in morphine after mastectomy.

The duration of hospitalization being lower than 48 hours for this type of surgery, the investigators envisage an immediate follow-up in the Units of Care then at home, what will require a training of the hospital actors and at home (patient, family, visiting nurse, general practitioner).

Although proposed for several years, the CCP after breast surgery is still a little spread technique and few works had evaluated the pain at rest and at mobilization after mastectomy, the early rehabilitation, and to spread its use towards home, that is why we propose a randomized double-blind study ropivacaine / placebo in patients after mastectomy.

summary:
In patients with heart failure, the drive to the effort has demonstrated its safety and its interest. Patients with heart failure, endothelium-dependent peripheral vasodilatation is impaired by decreased activity of endothelial NO synthase. The rehabilitation training significantly improves peripheral endothelial function, and this improvement is correlated to the increase in exercise capacity. The impact on coronary endothelial function remains poorly documented, especially in non-ischemic dilated heart disease.

The main objective of this study is to investigate the effectiveness of cardiac rehabilitation on the restoration of coronary endothelial function in cardiac failure patient evaluated with Tomography Positron Emission 15O-H2O.

title: Effect of Inhibitors of the Proton Pump on Intestinal Transporters and Their Impact on the Pharmacokinetics of Dabigatran - Mechanistic and Clinical Approach -BIPP Study

acronym: BIPP

summary:
Dabigatran etexilate is a novel oral anticoagulant. It is indicated in venous thromboembolic prevention in orthopedic surgery and has recently shown greater efficiency and tolerance as anticoagulants in preventing thromboembolism in atrial fibrillation. However, it increases the risk of gastrointestinal bleeding compared to standard treatment (AVK) [3]. In these circumstances the risk / benefit of dabigatran could be improved by combining it with gastric protectors such as inhibitor drugs proton pump (IPP).

Investigators want to evaluate the pharmacokinetic and pharmacodynamic effects of co-administration of these two IPP (omeprazole, rabeprazole) with dabigatran in healthy subjects.

title: Association Between Serum Periostin Levels and Cortical Porosity in Patients With Secondary Hyperparathyroidism

summary:
Based on the evidence that periostin is specifically involved in intra-cortical remodeling control, our working hypothesis is that assessment of its concentration in the serum would be helpful in identifying patients with severe cortical porosity, a critical parameter in bone fragility. Periostin expression by osteoblasts and osteocytes is part of the bone cortical response to anabolic stimuli such as mechanical strain or intermittent increase in parathyroid hormone. However, it remains unknown whether this expression may participate as well to mechanisms that will lead to exaggerated intra-cortical remodeling and subsequent bone loss.

In rare clinical situations in which trans-iliac bone biopsies will be necessary to better understand their bone status in addition to densitometry and biological bone markers assessment, specific analyses using immune-staining techniques will be performed on the bone sample. Data from routine follow-up every six months will be also collected in this specific sub-group.

High resolution peripheral quantitative computerized tomography (HR-pQCT) gives the opportunity of performing a virtual bone biopsy providing information on trabecular and cortical microarchitecture in vivo. These microarchitectural parameters allow a more accurate evaluation of the alteration of the bone structure and therefore of the fracture risk as compared to current tools used in clinical practice such as densitometry. However, the availability of such HRpQCT facilities is limited and there is on-going development on the best way of measuring porosity for example. The definition of a biological profile including key proteins such as periostin and sclerostin involved in porosity mechanisms is therefore of great interest. A better understanding of the relationship between bone matrix components and parathyroid hormone effects also appears as critical. Follow-up of routine evaluation parameters reflecting bone status in a subgroup of specific patients could also provide new and additional information.

title: Feasibility Evaluation of Continuous Positive Airway Pressure (CPAP) in the Treatment of Obstructive Sleep Apnea Synchrone in the Acute Phase of Stroke

summary:
This project is focused on the treatment of obstructive sleep apnea in the acute phase of stroke. Stroke is a frequent pathology with a high morbidity and mortality rate. Although it has now been proved that obstructive sleep apnea syndrome (OSAS) is a risk factor of stroke, on the other hand, there is evidence that 50 to 70% of patients in the acute phase of stroke have obstructive sleep apnea (OSA) based on an apnea-hypopnea index (AHI) of ≥ 10. OSA is associated with worse functional outcomes and higher mortality in the post-stroke period. Profound hemodynamic fluctuations and hypoxia generated by sleep apnea are likely to aggravate cerebral ischemia, particularly in the acute phase of stroke in the potentially reversible ischemic penumbra. Continuous Positive Airway Pressure (CPAP) is the primary treatment for obstructive sleep apnea.

Yet, to our knowledge, there have been very few studies aimed at demonstrating the value of CPAP in the treatment of obstructive sleep apnea in the acute phase of stroke. Only one randomised trial has provided the means to document neurological improvement at mid term (1 month) in a targeted population.

Before undertaking a comparative study evaluating the efficacy of CPAP in the acute phase of ischemic stroke, it is worth evaluating the feasibility and tolerance of introducing CPAP at the very early stage of ischemic stroke. Therefore, the purpose of our study is to evaluate the feasibility of CPAP in the treatment of OSA in the acute phase of ischemic stroke.

summary:
Corneal topography allows the measure of the radii of curvature and of the thickness of the cornea. It is essential for diagnosis in ophthalmology and allows to highlight corneal irregularities such as a keratoconus, or too thin corneas which are a contra-indication for laser refractive surgery.

Several types of corneal topographers are commercially available. Some as the Orbscan(r), operate by analyzing the image of the patterns of a Placido disk associated with a light slit, allowing the collection of thousands of points of the anterior and posterior surface of the cornea. More recent systems such as the Pentacam(r) are based on automatic rotary cameras which capture images of the whole anterior segment of the eye. The aim of this study is to compare two topographs, the Pentacam(r) and the Orbscan(r) and, more specifically, the central corneal pachymetry measurements measured pre- and postoperatively.

title: New Diagnostic Strategy in Hypertrophic Cardiomyopathy Including a New Genetic Approach: A Multicentric Prospective Study

acronym: HYPERGEN

summary:
Hypertrophic cardiomyopathy (HCM) is an autosomal dominant disease characterized by unexplained hypertrophy of the left ventricle, often with predominant involvement of the interventricular septum, and characterized by myocyte disarray and fibrosis.

HCM is the most common familial heart disease with strong genetic heterogeneity, demonstrated over the past 20 years. Mutations in 11 or more genes encoding proteins of the cardiac sarcomere are responsible for (or associated with) HCM.

However, 30-40% of sporadic and familial cases of HCM are still genetically unlabelled. In addition, secondary HCM caused by Fabry's disease or amyloidosis, may mimic primary HCM and may be under diagnosed. This may result in a delay in accurate diagnosis and instauration of specific treatment, with possible clinical consequences for the patients.

For these reasons, we decided to apply a new diagnostic strategy for patients with newly diagnosed HCM, including the whole exome sequencing (WES) technology.

If correctly applied, this new technology has the potential to strongly reduce the diagnostic wavering leading to earlier diagnosis and genetic counseling in sarcomeric HCM and rarer forms of secondary HCM including Fabry's disease and amyloidosis, and also specific therapy set-up in secondary forms of HCM. It should also allow identifying new genes responsible for HCM.

title: Non Invasive Measurements of Intracranial Pressure in Patients With Malignant Glioma

acronym: GMaPIC

summary:
In patients at risk of increased intracranial pressure (ICP), ICP measurements require invasive transducers, usually with insertion of a catheter into the cranium, or through a spinal tap. These invasive modalities involve risks and pain and they can be done only in specialized care units, with a high associated cost.

A novel method for detecting changes in ICP has developed recently. The auditory hair cells emit sounds and electric signals in response to sound, which can be easily detected and measured non-invasively with the help of a microphone probe placed in the external ear canal or regular electrodes. Indeed, the cochlear aqueduct connects the cerebrospinal fluid (CSF) spaces to the inner ear in such a way that ICP and inner-ear fluid pressure equalize within seconds.

A symptom of intracranial pressure (ICP) was observed in glioma patient due to a combination of causes: the inflammatory reaction around the tumor, the mass effect of the tumor, secondary vascular changes, a change in the flow of CSF.

The evaluation of intracranial hypertension by increased ICP (invasive) is not used in the monitoring of intracranial tumors. It is then detected by using routine clinical signs, in combination with a standard imaging method (MRI), but still subjective.

The measurement of noninvasive ICP could allow earlier detection of relapse, and evaluate whether the increase in ICP precedes tumor clinical worsening and / or imaging.

title: Comparison of Corneal Stromal Tissue Consumption Values Estimated When Programming the Intervention Versus the Values Measured by Pre and Postoperative Topography

acronym: LATAC

summary:
In refractive surgery, stromal ablation depth is fundamental because it determines the thickness of the residual posterior wall. The posterior wall is an essential element that guarantees the refractive stability and the long term prevention of corneal ectasia after corneal refractive surgery. A minimum thickness of more or less 300 microns is universally accepted. Its calculation is based on well-known formulas, such as Munnerlynn ones.

With the excimer laser platform last generation WaveLight® Allegretto® EX-500 of Alcon, a new treatment option called "wavefront optimized" is offered for myopia, astigmatism and hyperopia. The ablation profile has been developed to save stromal tissue consumption and to favor the quality of vision, by optimizing connections between the optical zone and the transition zone of the photoablation. Alongside the theoretical formulas, evaluation of the depth of ablation may be defined by differential ultrasonic pachymetry or by topographical analysis pre and postoperatively. The latter is currently the method of reference to assess the corneal thickness.

summary: The vitamin D deficiency (25OHD) is very common and affects about 80% of the population of French osteoporotic women over 50 years [5]. It contributes significantly to bone fragility and consequently the risk of fracture. To remedy this deficit, it is necessary to provide a suitable and sustainable supplementation. Changes in vitamin D deficiency ranging from undetectable to a 25OHD value very close to 30ng / ml lead to differences in therapeutic regimens, specific to each clinician in the absence of precise data in the literature. No consensus on supplementation dosages and methods have been proposed so far. Also, given the frequency of vitamin D deficiency including osteoporosis observed in the population, it became necessary to establish a single, uniform regimen for all patients with osteoporosis

For that purpose, kinematic and neuromuscular parameters under microgravity are compared to normal gravity conditions. To induce postural responses among the test subjects, an electromagnetic maneuverable postural platform will be used in order to randomly elicit perturbations. Postural reactions will be quantified by means of mechanical and electromyographic data. In Addition, peripheral nerve stimulation will be used to assess the spinal excitability by means of H-reflex recordings. H-reflex measurements were chosen as they allow reliable information about inhibitory and facilitatory mechanisms taking place at the spinal level.


acronym: BrainDTI

summary:
Weightlessness profoundly modifies many physiological systems and especially the nervous system and the vestibular system. The changes in the nervous system are based in part on brain plasticity mechanisms, that is to say on modifications of neurons and their connections. They are the source of some of the behavioral response observed in the parabolic flight or in astronauts. For example, it is commonly observed that in the second and third days of parabolic flight campaigns with 3 flights, fewer participants are prone to motion sickness during the first day. Similarly, during their first trip into space, astronauts suffer 2/3 for 2 or 3 days of space sickness - special form of motion sickness - while this proportion is much lower in the second trip.

The hypothesis of this study is that short-term weightlessness as well as changes in the level of gravity experienced during parabolic flights, induce neuroplascity phenomena in brain regions involved in the integration of vestibular, visual and proprioceptive.

The goal is to objectify these plasticity phenomena, and assess their changes over time, using methods of Magnetic Resonance Imaging (MRI). A standard MRI will give an anatomical image of the brain. For this study, a variant called diffusion MRI (Diffusion Tensor Imaging - DTI) will visualize nerve bundles and their journey in the brain. The total duration of this review will be about ¾ hour.

The results of this study will be compared with those of an ongoing study of 12 astronauts who have the same MRI scans taken before and after a trip to the International Space Station. Investigators can then evaluate the effect of duration of exposure to weightlessness on the phenomena of neuroplasticity.


summary:
From previous parabolic flight campaigns completed by our research group investigators gathered data showing important changes in neuro-endocrine and also immunological changes. This experiment now will complete the data set-up obtained during the MARS500 study on how these respective individuals will re-act to highly physically and emotionally challenging situations during a parabolic flight.

This add-on experiment to MARS500 will enable answering to the following questions i) if the stress response systems - when compared for two conditions but in the same individuals - do react uniformly and ii) if those subjects prone to have adequate stress response pattern will show gradually less immune modulation effects.

The understanding of the complex interactions of stress and immunity under chronic and acute stress conditions might help to enable adequate health and immune monitoring and might as well suggest suitable countermeasures for the prevention of the unwanted immunological effects during long-term confinement and space missions.


acronym: AUTOCARD

summary:
As a direct consequence of exposure to microgravity, astronauts experience a number of physiological changes which can lead to serious medical implications. Most immediate and significant is the headward shift of body fluids and the removal of gravitational loading from bone and muscles, resulting in progressive changes of the cardiovascular and musculoskeletal systems. The cardiovascular systems is subject to rapid changes which has been demonstrated in studies of short term (shuttle) and long term missions to Skylab and MIR.

Our main hypothesis is that there is a linear relationship between the gravity level (0G, 0.16G, 0.38G, 1G, 1.8G) and the cardiovascular parameters (heart rate (HR), heart rate variability (HRV), blood pressure and blood pressure variability (BPV) as well the spectral analysis of HRV and BPV.


acronym: VITADCOG

summary:
Every year, nearly 30% of people aged over 65 fall at least once and about 15% fall at least twice. These falls can have serious consequences that are a significant threat to the independence and well-being of older people. From an economic perspective, the cost of medical care related to falls and resulting injuries is very high and continue to grow with the aging of the population. Therefore falls prevention is a public health priority.

Many data suggest that cognitive, common disorders in the elderly, is a major risk factor for falls and the elderly often have difficulty managing their parallel postural stability and other situations requiring attentional resources. Furthermore, the data used to evoke a role of vitamin D in the risk of falls in the elderly. Indeed, vitamin D has beneficial effects on muscle and on the human brain and several recent studies have shown the existence of positive relationship between serum 25 hydroxyvitamin D and cognitive function. These different actions may explain the beneficial effect of vitamin D supplementation on the risk of falling for practicing daily oral doses of vitamin D in the range of 700-1000 IU.

Our goal in this study is to confirm the existence of a link between vitamin D status and some areas of cognitive functions, and analyze the roles played by vitamin D deficiency and cognitive impairment in the occurrence of falls. The study will also seek the existence of a threshold level of 25-hydroxyvitamin D below which may arise cognitive disorders. The prospective follow-up of patients for 2 years will study the effect of correcting the vitamin D deficiency (initial correction and regular supplementation) on cognitive function, balance, walking and the occurrence of falls.

The study will be conducted in 150 subjects aged 50 years and over and fell in 150 subjects aged 50 and over at risk of falling. These patients will be enrolled in the Emergency Services, Orthopedics, Geriatrics, and Rheumatology of the University Hospital of Caen. All subjects will receive a dose of 25 hydroxyvitamin D, a comprehensive study of cognitive function, tests of balance and walking and assessment of activities of daily living and depression. All the examinations and tests will be carried out during the same half day. According to current recommendations, it will be prescribed a treatment with Vitamin D to subjects with a lowered rate of 25 hydroxyvitamin D (<30 ng / ml) to normalize the rate and will be advised doctors to prescribe regular supplementation vitamin D in order to maintain it in the standard rate (30 to 80 ng / ml). The effect of the correction of hypovitaminosis D, confirmed by controlling the rate of 25 hydroxyvitamin D, on cognitive functions, balance and walking will be analyzed 3 months and 9 months. During the two years following their inclusion in the study, subjects will be contacted by a phone call every 3 months during which will be recorded any falls they have been victims, as well as changes to their drug treatments, particularly case of regular intake of vitamin D supplementation.

If our hypothesis were true, it would be appropriate to consider a new approach to prevention of fractures involving the correction of vitamin D deficiency, cognitive rehabilitation and cognitive-motor drive in subjects with cognitive impairment.


acronym: DROITDEVANT

summary: The goal of this study is to objectively determine the perceived direction of the right-front by the subjects in weightlessness. The direction of the right-front has not been investigated to date with the measurements of the position of the eyes. The investigators will compare the intersection of the horizontal and vertical saccadic trajectories (jerky) with the apparent direction of the right-front indicated by the subjects when they look right front in the dark (LOOK) and that they indicate when they determine whether a visual target through the right-front apparent (PERCEPTION). Then, the investigators will compare these measurements between normal gravity and microgravity hypergravity during parabolic flight.


title: Evaluation of the Contribution of Transoral Robotic-assisted Surgery Using Da Vinci Xi for Head and Neck Tumors

acronym: TORS

summary: Head and Neck cancers are treated either with surgical resection followed by adjuvant radiotherapy, or with organ preservation strategies using definitive radiotherapy with or without concomitant chemotherapy. These treatments have long-time functional side effects and consequences on the quality of life. Transoral robotic surgery has been developing since 2006 by Weinstein and O'Malley in alternative to open surgery, to decrease the morbidity of the large surgical approach. The da Vinci device had the FDA approval and the CE mark in 2009 for transoral surgery of head and neck cancers, using previous generations of da Vinci. The last generation da Vinci Xi has received the FDA approval for laparoscopic surgery in april 2014 and the CE mark in june 2014 but has not been evaluated yet in transoral surgery. The objective of our study is therefore to study the feasibility of this transoral robotic surgery for head and neck cancers, using the da Vinci Xi.


summary:
3-D Ballistocardiography (BCG) recording was performed in microgravity during the Spacelab D2 missions on a single astronaut. The results from this experiment have been published in the literature: the influence of respiration have been demonstrated and the signal processing methodology for the reconstruction of the displacement in one cardiac cycle have been developed. A 3D-BCG sensor has been developed and a collaboration to perform a sustained microgravity experiment onboard the Russian segment of ISS has been initiated. To be integrated in the PNEUMOCARD device, this new sensor needs to be tested in microgravity before implemented on ISS.

The aim of the present parabolic flight study is to serve as a feasibility demonstrator and test bed in order to evaluate the feasibility of 3D-BCG in sustained microgravity and to test whether the sensitivity of the developed 3D-BCG sensor is appropriate


title: Functional Magnetic Resonance Imaging for High Throughput Curietherapy Planning in Prostate Cancer

acronym: FIBROP

summary:
Merge the data of ultrasound with that of the anatomical and functional MRI is necessary since the high dose rate Curietherapy is carried out under ultrasound guidance. The investigators will recruit prostate cancer patients to evaluate the quality of the data, their sensitivity to exam conditions (patient position, volume of endorectal probe, gold grains implanted before intensity modulated radiotherapy , IMRT) and to merge data from different sources with the purpose of estimating the opportunities of integration treatment plan for Curietherapy broadband.

The nuclear magnetic resonance imaging provides precise anatomical study, but also provides access to a functional approach to the tumor mapping of water diffusion coefficient (DW-MRI), for dynamic imaging with injection contrast agent (DCE-MRI) and finally by spectroscopic imaging (IRMS). This multimodality imaging project is part of a multidisciplinary context, involving close collaboration between clinicians, medical physicists, and physicists of the teams participating in this project (Institut Gustave Roussy and U2R2M-CIERM hospital Kremlin-Bicetre).


acronym: CORTICOG

summary:
Alongside a well-known physiological deconditioning, such as a decrease in muscle mass or bone demineralization, extended stays in weightlessness also cause cognitive dysfunction. However, the studies on this subject during space missions short or long term could not determine how these cognitive dysfunction resulted from a direct effect of weightlessness or a stress-related effect.

Analysis of electro-encephalography (EEG) using a standardized mapping method is used to study the changes of operation of the cerebral cortex as the near infrared spectroscopy (NIRS) is a reflection of changes in the cerebral hemodynamics. Their combined use is a relatively simple and economical method for studying brain changes in an environment where the normal brain imaging techniques can not be used.

The main objective of this experiment is to evaluate the alterations in brain cortical activity and brain oxygenation level induced by micro- and hypergravity conditions.

acronym: ADRECARD

summary:
Cardiological examination constitute one of the major directions in nuclear medicine for detection of myocardial ischemia in patients suspected of coronary disease. In Caen, they constitute 20% of the activity of nuclear medicine. Systolic heart failure (HF) ischemic or nonischemic origin represents a new area of activity of the nuclear cardiology. This is HF stratification study based on cardiac adrenergic function after injection of a tracer: I-123-MIBG. The team Caen nuclear cardiology is one of two teams recognized internationally in the field of evaluating the cardiac sympathetic innervation in cardiomyopathies. Numerous publications from 1992 to the present day have reported encouraging results for the daily use of this tracer in the evaluation of patients with LV dysfunction IC. Recently, interest in using the MIBG has been shown as a prognostic marker of HF in a prospective study of 961 patients. Typically, the camera used was an Anger camera with collimating Nai standard called parallel holes.

The main objective is to validate the measurements of cardiac adrenergic function evaluated by cardiopulmonary mediastinal reports and sympathetic innervation scores VG after injection of I-123-MIBG in 80 patients with heart failure.


title: Stimulus-response Associations in Parkinson's Disease Patients

acronym: SRlearning

summary:
In a computerized experiment, visual stimuli will be presented to the parkinson's disease patients and to the controls. They will respond to each image by acting on the keyboard in a specific manner. Each participant will repeat that task 384 times per session. A break will be inserted every 12 tests so that participants can rest.

The experiment consists of three sessions. Each image will be presented three times. For the first two presentations it is assumed that a link will be created between the image and the task, and the image and action. In the third presentation, the same task and the same action will be maintained or will be swapped. In this way, It can be checked whether associations thus generated will affect the performance of the participants when tasks and actions will be incongruent.

summary:
Early detection of viable residual tumor or early neoplastic recurrence represents a real challenge in monitoring patients treated with concomitant chemoradiotherapy squamous cell carcinoma of the upper aerodigestive tract.

The locoregional recurrence rate is indeed high (up 40%) over the first two years of this therapeutic method.

The conventional imaging methods such as CT and MRI appear limited in terms of sensitivity because of the many post-treatment changes are fibrosis, tissue edema and the tissue distortion.

PET-CT 18F-FDG proves to be a non-invasive, reliable for the detection of residual tumor and metastasis, even in the absence of clinical signs.

To date, the acquired CT examination in the same time and in the same position that PET is performed without iodinated contrast injection, used for anatomical identification and attenuation correction of PET fused images. The patient usually has a second CT imaging, centered on the neck with contrast injection iodized within the radiology department.

To date, no team has yet studied the interest of the PET-CT 18F-FDG coupled with a CT scan with contrast injection iodized in the diagnosis of early recurrence in head and neck malignancies while interest of the contrast agent injection has been demonstrated in ovarian neoplastic recurrence research, pancreatic and colon.

summary:
Malnutrition is currently a major factor of morbidity and mortality, which poses a major public health problem in developing countries but also, albeit to a lesser degree and for different reasons, for industrialized countries. It is recognized that in countries "of the North", from 30 to 60% of hospitalized patients suffer from dénutrition.

In any case, it is covered by an imbalance between the contributions and needs; the two main mechanisms are a delivery failure (fasting, ingesting difficulty ...) and / or increased requirements (hypermetabolism ...). In cancer patients the Aero-Digestive Upper Airways (VADS), this imbalance is even more pronounced than the two mechanisms exist and potentiate. Patients included in this study are a population at risk, because of their therapeutic containing at least radiotherapy. It is recognized that this form of therapy exposes dental complications, mucous, saliva. These complications have a deleterious effect on the nutritional status of patients.

The diagnosis, treatment and prevention of dénutritions have an important place in the therapeutic strategies of this type of cancer because it is events whose incidence and morbid consequences are high and for which there are appropriate nutritional treatments in most cas. While the complete correction of malnutrition generally passes by the effective etiological treatment of the causal pathology, therapeutic efficacy of the latter is often conditioned by the nutritionnel state.

In addition to these concepts, investigators wants to study the benefits of a diet followed during the irradiation phase of patients with head and neck cancers and New treaties. We propose a randomized, phase III, open, multicenter, to evaluate the impact of a dietary consultation at home on the life quality of patients with head and neck cancer including first therapeutic sequence involves radiotherapy more or less aware. The duration of the study is 24 months.

The main objective is to evaluate the impact of a dietary consultation at home on the life quality of patients with head and neck cancer including first therapeutic sequence involves a more or less sensitized radiotherapy.

title: Impact of an Intensive Multimodal Educative Program on Behavioral Disorders of Patients With Profound Multiple Disabilities and on the Quality of Life and Feelings of Caregivers

acronym: TDCHandi

summary: Profound multiple disabilities also called in French polyhandicap are defined by the combination of a deep mental disability and severe motor deficit with extreme restriction of autonomy. Life in institution for people with profound multiple disabilities induces emotional and educative deficiency and often conducts to behavioral disorders. These behavioral disorders also impact on quality of life and feelings of caregivers. An intensive multimodal educative program proposed to patients with profound multiple disabilities can improve their psychic well-being, reduce chronic pain and improve also quality of life and feelings of caregivers. The intensive multimodal educative program will be compared to the usual practice of educative program.

title: Stress and Emotional Memory : Functional Neuroanatomy of Post-traumatic Stress Disorder in Adolescents

acronym: SEME

summary:
A broad group of disorders is associated with severe stress existence in children or adolescents. The most characteristic result, and one of the most serious being the state of post-traumatic stress disorder (PTSD), whose main source consists of physical or sexual violence, and to a lesser extent, accidents public road or natural disaster, whose child was the subject or witness. PTSD is associated with a deleterious effect on cognition and including the mnemonic operation. The painful reminder of the traumatic event is one of the most disabling symptoms. However, there are many other memory disorders that experimental studies gradually update. They maintain a close link with emotional regulation that disturbed you know if PTSD. However the majority of studies on emotion and cognition and their relationship with brain activity took adult subject. Work in adolescents are few on the morphological study, on rare neurobehavioral and reduced to two studies of functional neuroimaging. Contrary to what is observed in adults, morphological studies report consistently, no reduction in hippocampal volume. There is no study in the idle state. Two studies in functional MRI, the first highlighted in PTSD patients inhibition of the activity of the anterior cingulate cortex (ACC) to stimuli such as to evoke the trauma, a second reported increased activity in the prefrontal cortex Median (mPFC) in a inhibition. The objective task of our study is to evaluate the impact of psychological trauma on brain structures involved in the emotional component of the memory (amygdala, hippocampus, prefrontal cortex in particular). For this, the investigators will take in 33 adolescents, including patients with posttraumatic symptomatology and matched controls free of trauma age, several neuroimaging exams, anatomical and functional. The functional review will include some rest and another in activation during episodic memory task designed to assess the influence of self-perception on memory impairment observed in patients. The investigators will check, for each group of patients and controls, the involvement of cortical structures in relation to the regulation of emotional memory (CCA, amygdala and hippocampus). The anatomy of the hippocampus benefit specific imaging methods developed in the unit INSERM U923. Endocrine correlates of stress tests will be studied by a fully-traumatic by salivary cortisol sampling.

This research will clarify the mechanisms involved in emotional and memory impairments secondary to psychological trauma, their relationship with self (judgment and self-esteem) and studying their morphological substrates. A longer-term goal is to offer help in the diagnosis and monitoring of young patients with posttraumatic symptomatology.

summary:
Type 2 diabetes is associated with early and diffuse abnormalities of endothelial function, especially in the coronary arteries, which are a factor of poor prognosis. Following acute coronary syndrome, the endothelial function abnormalities usually persist for several weeks before regressing. Their persistence 6-8 weeks after myocardial infarction is a poor prognostic factor. Investigators assume that global abnormalities of endothelial function in patients with diabetes may be additive with segmental abnormalities in revascularized myocardium, and contribute to worsening the prognosis in these patients. Furthermore, there is no published data showing any relationship between calcium score and endothelial function abnormalities in these patients. The investigators seek a relationship between calcium score and persistence of abnormalities of coronary endothelial function in these patients.

The main objective of this study was to compare coronary endothelial function by quantitative method (TEP at 15O-H2O) in diabetic patients and nondiabetic following acute coronary syndrome.

summary:
The prognosis of patients with heart failure has improved due to recent breakthrough in medical treatment and cardiac resynchronization devices. However, there is no paraclinical parameter to assess response to cardiac resynchronization therapy (CRT). This is a major issue since about a third of implanted patients will not be improved by CRT. CZT SPECT allows to perform myocardial perfusion imaging in less than 4 minutes and is able to study myocardial perfusion, viability, left ventricular function, but also ventricular asynchrony.

Using low-dose dobutamine gated SPECT and CZT camera, we aimed to assess left ventricular dyssynchrony in viable segments in patients with heart failure eligible for CRT.

summary:
Type 2 diabetes is a major public health problem because of its increasing prevalence and morbidity and mortality that accompanies it. Therapeutic management of this pathology, lifestyle measures, dietary and physical activity are fundamental. Their observance is unfortunately too often insufficient, leading to a therapeutic climbing with first oral antidiabetic (OAD) then the use of insulin therapy.

Yet there is now ample evidence that physical activity improves glucose control in these patients in particular improving insulin sensitivity after a training period but also after a single session of physical activity.

Neuro-myo-electrical stimulation (NMES) is used in common clinical practice in physical therapy, patients with neurological or after orthopedic surgery in particular. In fact, this method enables improvement of volume and strength, even for denervated muscles. Recent studies have also shown the benefits of NMES in situations of cardiac or respiratory readjustments. In addition, NMES is used by top athletes supplements classical training in order to develop muscle strength or speed recovery.

Investigators propose to test the impact of bilateral quadriceps NMES on insulin sensitivity in type 2 diabetic patients treated with OAD (excluding glitazone). To do this, investigators plan to assess their insulin sensitivity by the reference method of hyperinsulinemic euglycemic clamp before surgery, after a single session of bilateral quadriceps NMES and after a sequence of daily training 6 days a quadriceps NMES bilateral.

Investigators hope to show an improvement in insulin sensitivity by this method, which would constitute an alternative to physical activity in the treatment of diabetes type 2. This procedure would be particularly interesting in diabetic subjects with type 2 counter- indications or an inability to perform a conventional physical activity.

title: Pilot Study: Measure of the Potential Evoked With Electroencephalography and Electrocorticography by Electric Stimulation of the Brain During the Neurosurgery Awakened of the Infiltrative Glioma of Low Grade (OMS Type II)

acronym: PE&CE

summary:
This study is about an experimental biomedical monocentric search concerning twelves patients presenting a infiltrative glioma of low rank OMS type II and realizing a surgery awakened on the site of the CHU of Montpellier.

The objective of this search is to understand exactly how the electric impulses, delivered by the neurosurgeon to make a functional mapping of the brain during the surgery awakened by tumors infiltrates of low rank, propagate in this one and to identify the nervous networks inhibited by these electric impulses.

Having verified the eligibility of the patients and having obtained their consent, they will be included in the study. Before the beginning of the surgery, the electroencephalography activity of the brain of every patient will be recorded. Before and after the surgical resection, the electrocorticography activity will be recorded.

The collected data will then be analyzed, after the operation. Analyses will try to identify what we call potential evoked by the stimulation and which are small electric waves which appear after the electric stimulation was delivered.

title: Double Upper Limb Allograft: Intervention and Clinical Evaluation. A Pilot Study of 5 Cases

acronym: DAMIE

summary:
The case of patients with amputation of forearm on one side and arm on the other is particularly interesting to study because in this situation of handicap greater than a double amputation in forearm. We should bring a functional benefit to the patient with the transplant of forearm and this situation allows to have the best possible control to compare the result of the transplant of arm to that of forearm because it is realized at the same patient.

Amputation of both arms deprives patients of an elbow what establishes a major factor of limitation of autonomy and makes patients totally dependent for the realization of the essential gestures of the current life requiring the prehension (dress, dressing, food, hygiene of the elimination). The various equipments are not always adaptable and usable. Psychologically, an amputation in arm is unanimously considered as an infringement very badly accepted of the physical integrity and establishes a major handicap factor of family, professional and social exclusion.

The results of this study should allow a better appreciation of indications and modalities of care of biamputed patients with at least one lesion level above the elbow.

This clinical research will determine the potential place of a reconstructive surgery as allograft in biamputed patients on the basis of functional results and assessment of disorders of the body schema perception.

summary:
There are no equivalent experiment setups to create comparable changes of gravitation such as during parabolic flights. To determine the initial orthostatic responses of the cardiovascular system under the gravitational conditions of mars and moon is an essential step for a better understanding of 1) the fundamental functions of the human cardiovascular system (basic research) 2) specific impact of partial-g on the human heart, lungs and vessels in a spaceflight-context 3) approaches for countermeasure development against orthostatic intolerance on moon and mars (applied research).

Non-invasive measurement methods will be used to achieve the cardiovascular key values of the study: stroke volume (SV) and cardiac output determination by pulse contour analysis, impedance cardiography and inert gas rebreathing, beat-to-beat finger blood pressure measurement, heart rate and heart rate variability determination by ECG. All of these methods have proven their accuracy during parabolic flights. Nevertheless pulse contour analysis and impedance cardiography are known to provide only relative SV and CO values. Thus inert gas rebreathing gives us the possibility to calibrate these stroke volumes and cardiac outputs to absolute values. Success of this procedure was shown during former parabolic flights.

summary:
Cardiac exploration almost systematically requires the acquisition and / or calculating function indices. The ejection fraction (LVEF) is probably based index most widely used in all cardiac exploration methods. This relatively universal overall index has very many qualities. LVEF is widely used in clinical practice through the exploration and monitoring of all heart disease.

Current progress in the management of various cardiomyopathies pass through the detection of early attacks. This testing often takes place upstream changes in LVEF that remains long normal or normalized. Sensitive indicators capable of detecting early abnormalities of regional functions are essential in addition to conventional echocardiography. Various studies have shown the contribution of these new markers in early detection of abnormalities of the cardiac function. The most widely used indicator in these studies because of its high sensitivity to analyze the movements of the heart is the tissue Doppler. Tissue Doppler however has limitations in particular its dependence on the incident angle, which makes it impossible to correct analysis of non-aligned in the axis of the ultrasonic beam components.

A new way of exploring the regional function of the heart, speckle tracking, can analyze heart deformations along the principal axes of the heart. The advantage of this technique has been shown in various pathological situations. Currently, this technique is mostly used in longitudinal and transverse view 2D imposing multiple planes cuts. 3D potential of this technique is not currently known, acquisition of 3D technology is recent (2004) and dedicated software is confidential dissemination and unvalidated.

The validated technique, 3D reference analysis of myocardial deformation is tagged MRI. In the 90s, studies have demonstrated the feasibility of this technique, the ability to access all of the myocardial deformation in space and to define normal values. The cost of the procedure, duration, limited accessibility and post-processing very time consuming limited the scope of the clinical benefits of this modality.

Echocardiography has major advantages over MRI, particularly its high availability, low cost and flexibility of use. The ability to access with MRI as the 3D deformation of the heart is a new opportunity that it is essential to validate.

The main purpose of the study is to compare the strain values obtained 3D ultrasound to those obtained by MRI tagged in a control group and a group of subjects with an anterior infarction sequela.

summary:
Previous studies have neglected two important aspects for the China National Space Administration. First, while biomechanical models are very sensitive to the characteristics of the subjects, data have been collected on subjects with biomechanical characteristics very different from those of "typical" Chinese astronauts. Second, pure video analysis techniques and kinematic data lack the necessary acceleration information important to understanding the forces exerted during movement and control of human motion. While some studies used force and moment sensors to aid in robot torque control and human joint work estimation, investigators are unaware of any studies performed in a microgravity environment that have combined the kinetic force and moment information with acceleration measurements to enable more reliable motion tracking without the need for acceleration estimation.

This is why MICR0-G sensors and accompanying kinematic video system have been developed in order to provide for detailed analyses of the astronaut movement control strategy (joint forces and torques, kinetic and acceleration measurements). Knowledge of the joint torques permits us to calculate the joint and musculoskeletal dynamics required to execute the microgravity motions, as well to provide insight into the altered movement strategies in reduced gravity as compared to 1-G locomotion.

summary:
Parabolic flight is the only ground-based condition in which weightlessness (0G) can be created long enough for safely testing changes in human perception and behavior. In addition to the 0G period, parabolic flight generates equal duration periods of 1.8G, which present another unique opportunity to test the same responses to hypergravity and back to 1G.

Cognitive function, together with good oculomotor control, eye-hand coordination, and spatial orientation perception, is a critical subsystem that is used by the CNS in the control of vehicles and other complex systems in a high-level integrative function. Evidence from space flight research demonstrates that the function of each of these subsystems is altered by the transitions in gravito-inertial force levels. These neuro-vestibular alterations, unfortunately, correspond to mission phases where physical and cognitive performance are particularly critical for crew safety and mission success. To date, there is only limited operational evidence that these alterations cause functional impacts on mission-critical vehicle (or complex system) control capabilities. However, the true operational risks will be estimable only after the investigators have filled the knowledge gaps and when the investigators can accurately assess integrated performance in off-nominal operational settings.

Accurate perception of self-in-space motion and self-motion relative to other objects are critical to piloting, driving, and remote manipulator operations. Immediately after space flight, most crewmembers have reported some degree of disorientation/perceptual illusion, often accompanied by nausea (or other symptoms of motion sickness), and frequently manifested by lack of coordination, particularly during locomotion. Despite recent, intensive training, some Shuttle landings were outside of the desired performance boundaries. Scores indicating neurovestibular dysfunction in returning astronauts generally correlated with poorer flying performances, including a lower approach and landing shorter, faster, and harder. An underestimation of distance, coupled to an overestimation of tilt magnitude or misperception of the type of motion, could be at the origin of these poorer performances.

This study should confirm that the unloading of the otoliths in weightlessness induces an alteration in the egocentric reference during space flight. Errors in egocentric localization might contribute at a higher level to the computation of misleading world-centered representations, and therefore be partly responsible for illusory sensations and motion sickness symptoms during space flight, and postural instability and oscillopsia after returning in a reduced or terrestrial gravitational force level.

Beside their fundamental implications, the results of this study have also practical implications in the design of man-machine interfaces. Changes in judgment of distance in microgravity or in reduced gravity affect crew posture and reach, display orientation, and other visual cues, which should be considered in hardware and operations design.
