title: Testing for Dysautonomia in Patients Hospitalized for SARS-CoV-2 Infection (COVID-19) : COVIDANS Study

acronym: COVIDANS

summary:
A number of clinical features suggest the possibility of dysautonomia in patients infected with SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2).

At the same time, there is now strong experimental evidence that SARS-CoV-2 can cross the blood-brain barrier, probably via the olfactory nerves, and reach the brain stem, which is located in close proximity.

Damage to the brainstem nuclei could explain the suspected dysautonomic episodes, but also the severity of respiratory distress in infected patients, and the difficulty of ventilatory withdrawal encountered in resuscitation, potentially through damage to the ventilation control and regulation centers located in the brainstem.

The objective of this study is to record the long term variability in heart rate, reflecting autonomic balance, of patients screened positive for SARS-CoV-2 throughout their stay in conventional care units at the Saint-Etienne University Hospital, in order to see whether there is an autonomic imbalance at screening, whether the worsening of the autonomic imbalance precedes the worsening of the clinical condition, and how quickly the expected correction of the autonomic imbalance follows or precedes that of the disease.

title: Fast Exome for Diagnosis of Congenital Conditions in Infants Under 12 Months of Age Hospitalized in Intensive Care Unit

acronym: REUNIR

summary:
An early diagnosis of congenital malformations and suspected genetic conditions in critically ill infants is essential to perform specific adapted care, prevention, and give proper genetic counseling. However, etiologies are various and each of them is individually very rare. Thanks to next-generation sequencing technologies, diagnosis time frames have drastically decreased and the investigators have observed an increase in diagnosis yields.

This study aims to evaluate the feasibility of fast trio exome sequencing (less than 16 days between informed consent signature and the consultation for results to the parents) in infants under the age of 12 months hospitalized in Intensive Care Unit (ICU).

title: Blood Innate Biomarkers as Predictors of COVID-19 Disease Progression in Recently Infected Chronic Haemodialysis Patients

acronym: PredictCovid-D

summary:
SARS-CoV-2 induces over-production of inflammatory cytokines, and especially interleukin-6 (IL-6). The apparently strong association between blood levels of inflammaory cytokines and SARS-CoV-2 disease severity has led clinicians to evaluate the administration of steroids or anti-IL-6 antagonists in severely ill patients. As of this day, biomarkers capable of predicting clinical disease progression in Covid-19 patients with mild-to-moderate symptoms have not yet been formally identified. Identifying such markers and evaluating their predictive value may be exploited to guide patient care management, and as such forms the core objective of this proposal.

Because of strong inter-individual variations in the ability of innate immune cells to produce cytokines, the hypothesis the investigators formulate and intend to test is that innate IL-6 responsiveness varies between recently infected Covid-19 patients and could predict disease outcome.

To test this hypothesis, the investigators propose to follow recently infected chronic haemodialysis patients with moderate Covid-19 symptoms. These patients stand a higher risk to progress to severe disease. The investigators plan to collect a blood sample in these patients using a system whereby ex vivo cytokine production is initiated in the very same blood collection tube without prior separation and centrifugation, thus reducing labour and operator bias. After incubation with or without known innate immune stimuli, the cell-free phase from each collection-culture tube will be assayed for IL-6 content. Associations between IL-6 content and disease outcome (encephalopathy, transfer to acute care or death) will be determined in 115 Covid-19 chronic haemodialysis patients with moderate symptoms followed in 9 centers.

title: On-admission Multifactorial Evaluation of Inflammation as Prognostic Marker of Death in Patients Diagnosed With Coronavirus Infectious Disease (COVID-19) Syndrome

summary:
During this pandemic period, the goal of the health care system is to optimize the use of intensive care services for patients infected with SARS-CoV-2, given the frequency of complications that can lead to high mortality.

When patients with suspected or confirmed COVID-19 are admitted to hospital, whether or not they are symptomatic, there is currently no method to predict who will progress to complications requiring the use of intensive measures in 24-48 hours.

title: "Prospective Study Evaluating the Impact and Treatment of Thrombo-embolic Events in Patients With Cancer"

acronym: THEO

summary:
The overall incidence of deep vein thrombosis (DVT) and pulmonary embolism (PE) is 1 per 200 cancer patients, about 5 times higher than in the general population.

These events are of crucial importance, since nearly 10% of cancer patients died from thromboembolic events (EVT), making them the second leading cause of death in this population.

In hospitalized patients, the rate seems to have increase between 1979 and 1990 from 0.6% - 2% before 1990 to 4% since 1990.

Thrombotic risk in cancer patients is known and identified. Thrombotic complications affect the survival and quality of life of cancer patients.

Chemotherapy is a regular generator of cytopenia, the most prominent of which is thrombocytopenia. In addition, a prospective study of 107 cancer patients in our institution shows that almost 40% of patients over 65 years of age take anticoagulant or antiplatelet therapy.

In this specific population (i.e., with cancer and hypocoagulability), the occurrence of thrombosis poses particular problems. The prevalence and incidence of venous thrombosis in this situation is unknown and the behavior to be poorly specified.

Based on these considerations, The investigator propose a two-year prospective cohort study to explore the biological parameters of hypocoagulability and to assess the incidence and prevalence of DVT in thrombocytopenic patients on vitamin K antagonists. (AVK), anti-platelet aggregation (AGP) and / or direct oral anticoagulant (AOD).

In this study, the investigator means by hypocoagulability any situation modifying the normal coagulation system.

title: Association Between the Composition of the Bacterial Flora of Thrombi and the Etiological Origin of Cerebral Infarctions Treated With Thrombectomy

acronym: Bacillus

summary: Cerebral infarction is a major health problem. The two most common causes are atherosclerosis (30 to 35%) and cardio-embolic origin (35 to 40%). However, in 25% of cases the cause is undetermined, known as cryptogenic stroke or stroke of undetermined origin. Paroxysmal Atrial Fibrillation appears to cause a significant proportion of these cryptogenic cerebral infarctions. One of the major challenges in the management of cerebral infarctions is the prevention of recurrence. If the cause is atheromatous, treatment is based on platelet antiaggregants and the correction of cardiovascular risk factors. If the cause is atrial fibrillation, the treatment of choice is anticoagulation therapy. Cryptogenic strokes are managed with antiplatelet therapy. In past studies, the thrombi responsible for cerebral infarctions have been analyzed anatomopathologically to see if the composition of the thrombi could help identify the cause of the cerebral infarction. These studies have proved to be contradictory. The composition of the bacterial flora of cerebral infarct thrombi has not yet been studied, apart from some limited data on septic emboli. In myocardial infarction, the cause of which is almost exclusively atheromatous, bacteria of the periodontal flora have been detected in thrombi of ST-segment elevation infarctions. The causes of cerebral infarction are multiple. The hypotheses explored in this study are that there are differences in the composition of the bacterial flora of the thrombus depending on whether the cause is atheromatous or cardio-embolic and that the study of the composition of the thrombus could be used to identify the cardio-embolic cause in patients with cryptogenic cerebral infarction.

title: Body Composition and Bone Mineral Density in Patients With Psoriatic Arthritis and Changes After 6 Months of Treatment With Ustekinumab

acronym: STELARA-CC

summary:
There is not much body composition and bone mineral density data available for patients with psoriatic arthritis (rheumatoid arthritis) compared to control subjects.

The evaluation of the total fat mass and in particular of its abdominal distribution (visceral adiposity) is important because an excessive adiposity generates adverse effects on the health (hypertension, dyslipidemia, cardiovascular risk and resistance to the insulin).

In addition, data on changes in body composition and bone mineral density were not available under a new psA treatment, namely ustekinumab (anti-IL12 / 23 antibody).

It is proposed to conduct a pilot study to evaluate body composition, distribution (visceral adiposity) and bone mineral density in patients with psoriatic arthritis (versus control subjects) and their changes after 6 months of treatment with ustekinumab

title: Systematic Proposal of Fertility Preservation by Oocyte Freezing in Case of Benign Ovarian Tumors With High Risk of Recurrence

acronym: OFBOT

summary: Benign ovarian cysts are frequent during women's life. They are diagnosed with pelvic pain or fortuitously during an ultra-sonographic exam. In case of persistence,a surgery will be necessary to identify the nature of the cyst and assess its benignity. In some case, cysts are recurrent and multiple surgeries are needed leading to a significant risk of ovarian damage by follicular depletion. Oocyte cryopreservation is no longer considered as an experimental technique of Fertility Preservation since 2013 as it has been recognized to be efficient and safe. According to reproductive medicine scientific committees and the French ethic law, fertility preservation has to be proposed in every situation of infertility risk. To date, there is no cohort study dedicated to fertility preservation by oocyte freezing in this specific subgroup of patients. The purpose of the study is to prospectively evaluate the oocyte number and quality after controlled ovarian hyperstimulation in patients with recurrent ovarian cysts.

title: C5a Receptor Expression in Circulating Myeloid Cells in ARDS Secondary to COVID-19

summary:
The pathophysiology of ARDS is linked to an uncontrolled inflammatory response at the level of alveolo-capillary membrane, mediated by neutrophils and mononuclear cells. The complement system and anaphylatoxin C5a have shown central role in the recruitment of these pro-inflammatory cells and more broadly in the genesis of cytokinic storm syndrome. C5a acts via receptors C5aR and C5L2.

This is a preliminary study aimed at studying the expression of the C5a receptor on myeloid cells in peripheral blood of patients with ARDS secondary to COVID-19.

This study has of primary objective to show there is an overexpression of the C5a receptor in patients with ARDS secondary to COVID-19 compared to control patients (patients with COVID-19 without respiratory distress and healthy volunteers).

The medium-term objective is to develop a clinical trial to test the effectiveness of anti-C5aR antibody in this condition.

title: Pilote Study : Brain Exploration in Magnetic Resonance Imaging in Parallel Transmission Mode (pTX) at 7 Tesla on Healthy Subject at Poitiers University Hospital

summary: Magnetic resonance imaging (MRI) is a non-invasive imaging modality used in routine clinical practice for clinical diagnosis by visualizing the anatomical structure and in vivo function of certain organs. The development of ultra-high field MRI systems with 7.0-T or higher, gives access to a new field of exploration of the human body by improving the speed of acquisition but also a better signal-to-noise ratio (SNR) and better resolution. In order to fully exploit the potential of these ultra-high field MRI scanners, various technical issues must be adressed. Indeed, the non-uniformity of the transmission field is one of them leading to non-uniform images with spatially varying contrast. Thus the pTX (parallel transmission) mode using multiple transmission channels allows spatial and temporal control over the RF waves.

title: Can Dynamic Changes of Pulse Pressure Variation During Passive Leg Raising or a Tidal Volume Challenge Help Predicting Preload Responsiveness in Mechanically Ventilated Patients With Spontaneous Breathing Activity

summary:
Background: Predicting preload responsiveness by using dynamic indicators before administering fluids to critically ill patients is nowadays routinely performed at the bedside. Unlike other dynamic indicators of preload responsiveness that require cardiac output monitoring, pulse pressure variation (PPV) can be simply obtained via an arterial catheter . However, PPV is not reliable in mechanically ventilated patients with spontaneous breathing activity. We hypothesized that an increase in PPV after a tidal volume (TV) challenge (TVC) or a decrease in PPV during passive leg raising (PLR) will predict preload responsiveness in such cases.

Objective: to examine if the change in PPV during PLR and after a TVC can predict preload responsiveness in patients with mechanical ventilation and persistent spontaneous breathing

title: Towards the Use of Instrumented Tests for Screening the Risk of Falling in Patients With Chronic Illness.

acronym: DETECACTI

summary:
In patients with chronic illness, screening for falls and their health consequences are major public health issues. Muscle weakness, gait and balance disorders are among the most common risk factors for falling. Assessing these parameters would thus be a crucial step in the evaluation of the risk of falling, allowing to more precisely orient the management strategy. Combining inertial unit sensors with clinically validated tests can provide additional information to improve the assessment of fall risks. We therefore propose to constitute a monocentric exploratory study, testing a prognostic screening tool, in patients suffering from a chronic pathology, in order to assess the risk of falling in this population.

Considering the relationship between muscle weakness and the risk of falling, we can assume that a deficit in muscle strength will result in less vertical acceleration which could point to a muscle cause of the balance disorder and thus allow a finer detection of the risk of falling. On the other hand, we hypothesize that spinal static disorders in chronic pathologies and in particular osteoarthritis, as well as balance disorders linked to impaired deep sensitivity lead to an increase in oscillations of the trunk when walking which can cause postural balance disorders thus increasing the risk of falling.

title: Study of the Modifications of the Immune Microenvironment Induced by Neoadjuvant Chemotherapy in Triple-negative Breast Cancers

acronym: MIMOSA

summary:
The prescription of neoadjuvant chemotherapy becomes a standard in women with HER2-positive or triple-negative breast cancer and allows a complete histological response (pCR) which represents a prognostic factor for survival. . The problem for patients who are not pCR is that they are currently receiving non-personalized adjuvant systemic treatment.

The identification of biomarkers present in the residual disease would be a criterion to guide the choice of post-neoadjuvant adjuvant systemic treatment, in order to personalize it.

At the present time, there is no published study describing extensively the immune micro-environment (ME) in breast cancer, whether before or after chemotherapy, nor its modification induced by chemotherapy.

The team therefore propose to study in a retrospective and monocentric series, the modifications of the immune ME induced by a "standard" neo-adjuvant chemotherapy in patients with triple-negative CS, whether they are in complete histological response or not (n = twice 50).

The main objective of this project is to describe the changes in the immune ME of triple-negative breast cancers induced by neoadjuvant chemotherapy for all patients (in pCR or not):

Quantification of TILs and subtypes of TILs (CD4 and CD8)
Expression of the three immune checkpoints that are PDL1, TIM3 and LAG3
Describe the organization of the immune system (immunostaining on the same slide of the PDL1, TIM3 and LAG3 immune checkpoints)

title: Use of Lung Ultrasound in Patients Suspected of COVID-19 Infection in the Emergency Room

acronym: COVILUS

summary: Covid-19 (English acronym meaning coronavirus disease 2019) is an emerging infectious disease caused by a strain of coronavirus called SARS-CoV-2. The current pandemic has resulted in a significant number of admissions in the emergency room (ER) due to suspicion of COVID-19 infection. Use of lung ultrasound is standard practice to diagnose acute respiratory failure in ER. Recently, typical lung ultrasonographic characteristics of COVID-19 disease has been described. During the COVID-19 pandemic, the use of this tool could be of interest in order to allow an early, simple and reliable triage in patients with suspected COVID-19 infection admitted in ER. In addition, the visualization of early signs in specific areas could be a predictive marker of the severity of the disease. The objective of this project will be to study the association between the signs on lung ultrasound and the result of RT-PCR in patients with suspected COVID-19 infection in the ER.

title: Impact of Giving Birth During the Covid 19 Pandemia on Postnatal Women's Depression

acronym: DEPRECOVID

summary:
Postnatal depression is an important problematic in French population with approximatively 10 -20% of women who suffer from postnatal depression. This pathology may have strong negative impact on both women and neonate's health.

The women's satisfaction degree in front of childbirth is an important factor associated with postnatal depression since women unsatisfied of their childbirth and/or women with a complicated childbirth are more encline to suffer from postnatal depression.

It is likely that the actual context of Covid 19 pandemia and the change in obstetrical cares organization may have a negative impact on women's satisfaction about their childbirth and so a negative impact on the risk of postnatal depression.


title: Variability of Heart Rate as a Marker of Complication of Colorectal Surgery

acronym: VFC COLORECTAL

summary: Heart rate variability reflects the autonomic nervous system on the intrinsic activity of sinus node cells. Sympathetic hyperactivity is an adaptation to stress, while parasympathetic hyperactivity is present at rest. Thus, any variability in the heart frequency rate reflects variations in sympathetic and parasympathetic components in the autonomic nervous system. Failure to return to normal or a reduction in the variability of the heart rate in the postoperative period is correlated with complications in colorectal surgery.

title: PROne Positioning in coVID-19 Oxygeno-dependent Patients in Spontaneous Ventilation (PROVID Study)

acronym: PROVID

summary:
The COVID epidemics is responsible for a huge number of death following COVID acute respiratory failure. First instance treatment includes oxygenotherapy up to 15L/min in spontaneous ventilation. However COVID infection can ultimately lead to an acute respiratory distress syndrome (ARDS) requiring mechanical ventilation in the intensive care unit (ICU). Guidelines on ARDS management are based on small ventilation volume (6 mL/kg), a pulmonary end expiratory pressure (PEEP) chosen to get the best pulmonary compliance, a plateau pressure lower than 30 cm of water and daily prone positioning when PaO2/FiO2 ratio is lower than 150. In ventilated ARDS patients, prone positioning has shown survival improvement. Though they applied this optimized management of ARDS patients, Chinese intensivists have recently reported mortality rate higher than 50% in ARDS COVID patients requiring intubation and mechanical ventilation. Before being intubated and admitted to ICU, COVID patients require increasing rate of oxygen delivery. From the start of the epidemics, we have observed that an oxygenotherapy rate higher than 3L/min at the initial phase of the disease was associated with a high risk of severe acute respiratory distress (30%)

The investigators hypothesize that prone positioning in patients in spontaneous ventilation (not tubed) from the stage of oxygenotherapy higher than 3L/min (to get an SpO2 of 95% or higher) would prevent respiratory worsening and the need for intubation. Prone positioning is easy to apply in patients in spontaneous ventilation since they can change position by themselves.

title: Evaluation of Acute Mechanical Revascularisation in Large Stroke (ASPECTS 0-5) With Large Vessel Occlusion Within 7 Hours After Stroke Onset or Last Known Well

acronym: LASTE

summary:
Stroke represents the fourth leading cause of death in industrialized nations, after heart disease, cancer, and chronic lower respiratory disease. The overall burden of stroke will rise dramatically in the next 20 years due to an ageing population. Approximately one-quarter of the patients suffering a stroke die within one year after the initial event and stroke is a leading cause of serious long-term disability. Acute ischemic stroke (AIS) due to large vessel occlusion (LVO) is a potentially devastating event, with a poor prognosis in the absence of timely revascularization. Whether in patients with large anterior circulation stroke, direct mechanical intervention is equally effective, superior or inferior to bridging thrombolysis remains a matter of debate.

Thus, this procedure, is now the recommended standard of care for selective patients with LVO in the anterior circulation. When performed with newer generation devices (mainly stent retrievers), more stringent imaging selection criteria and more efficient workflow than in previous trials, significantly reduces disability rates after AIS caused by LVO in the anterior circulation.

The STAIR (Stroke Treatment Academic Industry Roundtable) meeting aims to advance acute stroke therapy development through collaboration between academia, industry, and regulatory institutions. In pursuit of this goal and building on the available level I evidence of benefit from endovascular therapy (EVT) in large vessel occlusion stroke, STAIR IX consensus recommendations were developed that outline priorities for future research in EVT.

title: Exosomes Implication in PD1-PD-L1 Pathway Activation in Obstructive Sleep Apnea Syndrome

acronym: ExoSAS

summary:
An increased occurrence of cancer associated mortality has been described in patients with Obstructive Sleep Apnea Syndrome (OSAS). This association might be partially explained by an impaired cellular immune response that has been described in OSAS. Is has been suggested that OSAS impact immune cells by upregulation of the PD-1/PD-L1 pathway. Exosomes are small membrane vesicles released by numerous cells in the bloodstream. Exosomes have been shown to be implicated in cancer cells proliferation via a PD-1/PD-L1 pathway activation.

This study will evaluate exosomal PD-1/PD-L1 expression in patients with OSAS as compared to controls and will further investigate their impact on immune cells function and proliferation capacities.

summary:
The clinical evaluation of a patient with a cognitive complaint requires neuropsychological tests, evaluating the integrity of memory and other cognitive functions.

The initial evaluation is made most often by a doctor (general practitioner). In case of need for further examination, a neuropsychological report is made in consultation memory by a neuropsychologist, with further cognitive tests.

The Cognitive Neurology Center at Lariboisière Hospital - Fernand Widal has developed a tool on a digital tablet or smartphone to evaluate cognitive functions: MemScreen.

The purpose of this study is to validate this new neuropsychological test on tablet compared to the neuropsychological reference tests.

summary: Clinical ultrasound has become essential in emergency medicine. The guidelines are to use of echocardiography in specific contexts: dyspnea, hypotension or chest pain. The evaluation of left ventricle ejection fraction (LVEF) is one of the basic objectives of echocardiography. The reference assessment in emergency medicine is visual assessment. It suffers from poor inter-observer reproducibility. Pocket ultrasound scanners seem to meet the constraints of point-of-care ultrasound. A new tool is available on a pocket ultrasound device: the automatic evaluation of LVEF. Its interest could be to have a better inter-observer reproducibility than visual evaluation.

title: Study of Prevalence and Risk Factors of Hypovitaminosis C in Long Term Care Unit

acronym: Vitamin C

summary: The clinical finding of skin rashes which appear after a vitamin C deficiency in Long Term Care Unit leads us to believe that the institutional diet could predispose to this kind of deficiency. Vitamin C has a key role into the struggle against oxidant stress and is involved into the connective tissue formation of the skin and the vascular endothelium. Vitamin C deficiency affects currently 15 to 25% of the elderly over 65 years old reaching 15% women and 20% men after 65 according to Johnston and Al. It concerns mainly the people in precarious situations (persons without fixed homes, ethyl-smoking persons) and elderly over 65 years. Hypovitaminosis C, defined by plasma level between 5 mg/L and 15 mg/L (28.41 to 85.23 µmol/L), is currently undiagnosed, especially with people with a risk of food deficiency and its prevalence increases with age. The treatment consists of a daily oral supplementation of 1 gram of vitamin C/d for 15 days. A minimum intake of 10 mg/D of vitamin C is required to prevent scurvy and maintain a total pool of 350 mg. A diet modification by a systematic intake of 2 glasses of fresh orange juice and/or the consumption of raw fruits and vegetables would prevent the appearance of scurvy.

title: To Simulate Prismatic Adaptation in Healthy Subject : a Technical Innovation in Favour of Autonomy and Independence in Daily Life Following a Brain Injury

acronym: PRIS'TUEL

summary:
Unilateral neglect is a neuropsychological disorder reflected by a disturbance in the spatial exploration and distribution of directed attention affecting the contralateral part of space and body relatively to the brain lesion. The chronic aspect of this pathology leads to a poor progression following rehabilitation and a decreased independence of patients in daily life. Thus, it is necessary to set up efficient and long lasting therapies for unilateral neglect patients to improve their daily quality of life. Prismatic adaptation is now a classical method which allows patients to improve their neglect through corrective pointing movements in response to a lateral displacement of the visual field. A large and growing body of literature has investigated prismatic adaptation as a very promising rehabilitation method, improving both visuomotor and cognitive features of unilateral neglect. However, its effects are somehow irregular and clinical applications of this method are still limited. The necessity for patients to come to the hospital to take advantage of prismatic adaption sessions draws some limitations about our knowledge concerning 1) the temporal dynamic of prism adaptation effects on a long-term basis and 2) the optimal duration of treatment (most of the time constrained by the hospitalization duration) and its therapeutical effects on a very long-term basis. Moreover, a large number of patients also suffer from motor deficits which reduce the possibility to optimize the prismatic adaptation session.

Thus, the aim of this project is to develop and validate others modalities of prismatic adaptation which can be applied at home and for a longer duration. These modalities should allow the investigator to get insights about the temporal dynamic of prismatic adaptation on the cognitive system. First, the investigator will investigate the effects of a prismatic adaptation modality using virtual reality to reproduce the lateral displacement induced by the prismatic goggles. He will also investigate prismatic adaptation induced by motor imagery, i.e. with mental representations of pointing movements without concomitant motor execution. This project could enhance the fundamental knowledge and enable to design new modalities of therapeutical use of prismatic adaptation (virtual or imaged) so as to allow a home-based treatment and follow-up. Thus, the aim of this project is to demonstrate the implication of similar mechanisms through different modalities (virtual and imaged compared to classical application) and the feasibility of these new modalities of healthy subjects. Thereafter, the aim will be to use knowledge acquired during this project to set up clinical trials to test for the efficiency of these modalities on a long-term basis in a pathological population.


title: Comprehensive Study of Social Representation of Platelet Transfusion in Patients Followed for Advanced Hematological Malignancies (R-PLQ)

summary: Limited data is available for end of life care in hematologic malignancies, moreover with thrombocytopenic patients. Thrombopenia is a frequent complication, specific of bone marrow involvement in those diseases or its treatments. Yet, a few studies was interested in, whereas platelet transfusion is the only treatment indicated. As it represent a scarce, limited resource, the ethical principles are in conflict in this setting and there's a lack of recommendation. The final decision is take by the clinician and his patient, but no study exist in representation of the two parts. We provide a qualitative study to understand what this decision is made of.

title: Serology COVID-19 From the Cornwall Hospital Union

acronym: ROCOCO

summary:
Coronavirus (COVID-19) is a pandemic-like disease caused by a new coronavirus called Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCoV-2) isolated in China in 2019. Clinical manifestations vary widely from one individual to another, from asymptomatic carrier to a febrile cough that can rapidly lead to acute respiratory distress syndrome. Since the beginning of the COVID-19 epidemic, screening by chest X-ray (RT) and polymerase chain reaction (PCR) SARS-CoV-2 conducted by the Cornwall Hospital Union laboratory has shown that among symptomatic patients and hospital staff suspected of being COVID-19, only 7.8% were attributable to COVID-19. Two nosocomial clusters were also identified, in the emergency department (10 carers) and in the cardiology department (6 carers and one patient). However, direct diagnosis by RT-PCR has sensitivity limits and can lead to false negative results when the subject is indeed suffering from COVID-19. This lack of sensitivity is inherent to the technique on the one hand, but also to the quality of the sample and the kinetics of the infection. Indeed, the virological window during which the virus is present in the respiratory mucous membranes sampled seems relatively narrow, hence a progressive negativation of the respiratory samples as the disease progresses. Moreover, clinical symptoms vary from one individual to another, and it is now recognized that some infected persons are asymptomatic but carry the virus. Thus, the use of a second diagnostic technique is a necessity, and serology could be a relevant diagnostic support.

In the literature, several publications report the performance of COVID-19 serology in clusters of cases or cohorts of subjects. The serological techniques employed are variable (target epitopes in particular) and frequently homemade. Serology is mainly studied in comparison or association with RT-PCR in order to highlight the increased performance of COVID-19 diagnosis when the two techniques are combined. Correlation with chest CT imaging data is also encountered.

Numerous serological tests are therefore being tested to determine retrospectively whether the individual has been exposed to the virus by looking for specific antibodies to the virus. The supreme health authority has drawn up specifications dated 16 April 2020, defining the methods for evaluating the performance of serological tests detecting antibodies directed against SARSCoV-2 in order to provide a framework for these practices. Several clinical studies are also underway, in particular to assess the kinetics of the appearance of the antibodies, whether these specific antibodies would be protective and whether their appearance would coincide with a cessation of contagiousness. Thus, the main objective of this study is to evaluate the diagnostic performance of the COVID-19 immunoglobulin (IgG) Dia-Pro serological test, in view of its deployment at the Cornish Hospital Union Laboratory. Subsequently, given the low prevalence of COVID-19 in Brittany and the risk of a second epidemic wave when the confinement is lifted, the evaluation of the seroprevalence of the staff of the Cornish Hospital Union is necessary in order to assess the attack rate of COVID-19 within the establishment and particularly within departments where nosocomial clusters have been reported; and to prevent the impact of deconfinement. Indeed, knowledge of the proportion of immunized personnel and its distribution according to services will make it possible to establish internal recommendations and to effectively manage personal protective equipment inventories, in conjunction with the deconfinement strategy that will be implemented by the government. The goal is to protect hospital staff from overexposure to the virus;

summary: The objective of the study is to validate a screening tool for auditory processing disorder in children of 7 to 13 years old. This screening tool was created based on literature and combines a questionnaire and a mini-battery of tests composed of verbal and nonverbal assessments.


title: Multimodal Imaging Analysis, SD-OCT and OCT Angiography, Retinal Variations Observed in Dialysis Patients

acronym: OCTADIAL

summary:
Little knowledge exist on the short and long-term ophthalmological effect of the dialysis. Some studies stated a variation of the thickness subfoveal choroidal before and after a session of dialyse as well as variations of the coat of optical fibers measured in OCT.

The Optical Coherence Tomography angiography OCT is a not invasive imaging technique which is now a part of examinations of investigation in imaging of retina. This technique allows to study the retinal macula vascularization without injection of contrast agent and thus allows to deepen the knowledge in medical domains where the exploration was to limited because of the invasive character of the examinations.

The hypothesis of this project is that hemodynamic change during the hemodialysis may lead fine variations of the retinal vascularization in the short-term (the day of the dialysis) but also in the longer term (over 1 year).

title: Effectiveness of a Condensed Functional Restoration Program for Patients With Chronic Low Back Pain: a Study of 193 Patients

acronym: PRAMH

summary:
The aim was to assess the effectiveness of a condensed functional restoration program (CFRP) for patients with chronic low back pain and professional activity.

Methods: Longitudinal 1 to 3 months study of patients with non-specific chronic low back pain in one tertiary care hospital, participating in a CFRP (complex interprofessional intervention over 4 days). The primary outcome was the Oswestry Disability Index (ODI) (0-100 scale). Secondary outcomes included pain, quality of life (EQ5D), patient acceptable symptom state, presenteeism, absenteeism and psychological distress (Hospital Anxiety and Depression scale). Outcomes were compared using paired sample Student's t-test or Chi2 between baseline and last follow-up. Logistic regression was used to identify factors associated with better response (improvement of ODI higher than 12.8) and included baseline demographic, psychological and physical assessment variables.

title: Cohort of Patients With Covid-19 Presenting Neurological or Psychiatric Disorders: An Observational Study of the Covid-19 Neurological and Psychiatric Manifestations

acronym: CoCo-Neuro

summary: Covid-19 pandemic now affects more than two million people worldwide. The neurotropism of the virus is assumed by its frequent association with neurological symptoms (anosmia, ageusia, headaches) but the extent of the central or peripheral nervous system involvement and the associated symptomatology remain poorly known for now. The main objective of this study is to describe the neurological and psychiatric manifestations occurring in the context of Covid-19 infection in patients hospitalized or followed-up in the APHP.SU hospital group. A better understanding of the neuropsychiatric impairment related to Covid-19 would improve the management of these patients in the acute phase, and knowledge of subsequent complications would allow adapting their rehabilitation and follow-up. The precise phenomenological description of these manifestations and the imaging, biology and neuropathology data will be compiled from the data collected by the physicians in charge of these patients as part of their inpatient or outpatient care. This study will also allow collecting unusual clinical manifestations from patients followed for neurological or psychiatric pathology in hospital departments and presenting a Covid-19 infection, in order to optimize the reorganization of their management, follow-up and rehabilitation in the epidemic context.
