Clinical trials

Chronic Obstructive Pulmonary Disease (COPD) is a chronic multisystem disease frequently associated with peripheral muscle dysfunction, which is strongly linked to prognosis and survival. Pulmonary rehabilitation is a cornerstone of COPD management and includes both cardiorespiratory endurance training and muscle strengthening exercises. Although these components are routinely combined within rehabilitation programs, the optimal order in which they should be performed during the same training session remains unclear. In healthy individuals, performing endurance and strength exercises in different sequences within a single session may influence muscular adaptations, a phenomenon referred to as the intra session interference effect. This effect has never been studied in patients with COPD undergoing pulmonary rehabilitation. Given the high prevalence and clinical importance of muscle weakness in COPD, optimizing exercise prescription may improve functional outcomes and long term benefits. This multicenter randomized controlled trial aims to compare two pulmonary rehabilitation strategies that differ only in the order of exercise administration. Participants with moderate to severe COPD will be randomly assigned to perform either muscle strengthening before endurance training or endurance training before muscle strengthening during each rehabilitation session. The primary objective is to evaluate the impact of exercise order on lower limb muscle strength, assessed by the Five Times Sit to Stand test at the end of the rehabilitation program. Secondary objectives include assessment of exercise capacity, dyspnea, muscle and inflammatory biomarkers, tolerance, and adherence to the rehabilitation program, as well as follow up evaluations up to 12 months after completion. The results of this study are expected to provide evidence to optimize pulmonary rehabilitation programs for patients with COPD and to inform clinical practice regarding exercise sequencing.

Periodontal diseases and dental pathologies are highly prevalent oral diseases. Thirty-three to fifty percent of adult population presented at least one untreated caries and more than 50% of French population are affected by severe periodontitis. These diseases affect dental organ or periodontal attached system but could have negative impact on general health, quality of life, word and individual well-being. Association between chronic diseases as diabetes, rheumatoid arthritis, cardiovascular diseases, and oral health have been well investigated. Dental and periodontal diagnosis is dependent of various clinical parameters time consuming and dependent operator. It represents a public health challenge. Informatic analysis detecting diseases could be a time gain and a more precise diagnosis tool. Today, any software or algorithm allow automatized detection, clinical qualitative or quantitative indices recording while these informations are present in numeric models

Preload responsiveness and venous congestion have largely been investigated independently in recent literature. However, recent data report a similar incidence of venous congestion regardless of fluid responsiveness status, challenging the concept of a linear continuum between preload independence and fluid intolerance. These findings support the need for a more individualized hemodynamic management strategy that takes venous congestion risk into account. The right ventricle plays a central role in this framework. Its function is to maintain an adequate venous return pressure gradient to ensure cardiac output while limiting upstream venous congestion, under strong dependence on its afterload. In physiological conditions, the right ventricle adapts to changes in afterload by increasing contractility to preserve right ventriculo-arterial coupling and optimize its performance. In chronic cardiopulmonary diseases, right ventriculo-arterial uncoupling is a well-established prognostic factor, including the presence of occult uncoupling revealed by fluid loading. In critically ill patients, right ventricular systolic dysfunction associated with venous congestion-defining right heart failure-is strongly associated with increased mortality, as is right ventriculo-arterial uncoupling itself. To support the concept of fluid tolerance, the investigators hypothesize that impairment of right ventriculo-arterial coupling may exist or occur during fluid loading in critically ill patients, independently of preload responsiveness, and may be associated with worsening upstream venous congestion.

Juvenile idiopathic arthritis (JIA) is a rare chronic inflammatory rheumatic disease that begins during childhood and may persist into adulthood in many patients. In addition to joint pain, swelling, and long-term articular damage, chronic inflammatory diseases may also be associated with early sarcopenia, defined as a loss of muscle strength and muscle mass. While this association has been described in adult inflammatory rheumatic diseases, it has not been well studied in patients with JIA. The aim of this study is to screen for sarcopenia in adolescents and adults with JIA in France. Sarcopenia will be assessed using validated questionnaires, hand grip strength measured with a Jamar dynamometer, and body composition measured by dual-energy X-ray absorptiometry (DEXA). Completion of validated questionnaires will assess nutritional status, fatigue, physical activity, and functional impact. Socio-demographic and clinical data will also be collected from medical records. This multicenter cross-sectional study will be conducted between June 2026 and October 2027 in 11 French hospitals. Eligible participants are patients aged 15 to 40 years with JIA diagnosed according to ILAR criteria and followed in a French hospital. This study will provide the first estimate of sarcopenia prevalence among patients with JIA in France. It will also help identify factors associated with sarcopenia and its impact on daily functioning and quality of life. In the longer term, the findings may help clinicians better identify patients at risk and support earlier management focused on disease control, physical activity, and nutritional care.

With 41,000 deaths per year, alcohol consumption is the second leading cause of preventable mortality in France. Nearly 3.4% of adults engage in excessive and chronic alcohol use, meeting criteria for Severe Alcohol Use Disorder (SAUD). SAUD is associated with cerebral and cognitive alterations, including deficits in social cognition. These deficits manifest as difficulties in perceiving and interpreting social cues during interactions and encompass, in particular, the recognition of emotional facial expressions and the accurate attribution of others' beliefs, emotions, and intentions (i.e., theory of mind). Such alterations contribute to interpersonal difficulties and psychological distress and are recognized as risk factors for the development and maintenance of SAUD. To date, social cognition has primarily been explored through behavioral tests, providing a description of deficits without examining their neuro-structural correlates. Moreover, no neuroscientific study has investigated the impact of sex and concomitant tobacco use on social cognition and associated brain structures in SAUD, although these factors are known to influence both social cognitive abilities and cerebral organization in this disorder. Finally, the everyday consequences of these alterations on social functioning and the trajectory of alcohol consumption remain poorly explored. In this context, the present project aims, first, to explore the neuro-structural correlates of social cognition deficits in SAUD using psychometric assessments (i.e., emotion recognition, theory of mind) combined with magnetic resonance imaging (MRI). The impact of sex and tobacco use will be accounted for by including these variables as covariates in statistical analyses. Second, the project seeks to assess the daily-life impact of social cognition deficits on the social functioning of individuals with SAUD (i.e., quantity and quality of social interactions) and on the evolution of alcohol use behaviors six months after hospitalization (i.e., risk of relapse). The study will include two participant groups: individuals with SAUD and age-, sex-, and education-matched control participants. The expected results will refine our understanding of social cognition alterations in SAUD, thereby contributing to the improvement of current neuroscientific models. These advances will pave the way for the identification of potential targets for prevention programs and therapeutic interventions.

This is a double-blind interventional superiority study evaluating the efficacy of suprascapular nerve block in addition to conventional therapies for adhesive capsulitis. Adhesive capsulitis is a pathology that results in reduced shoulder mobility due to retraction of the periarticular capsule. It may be primary or secondary to traumatic or neurological events, or associated with diabetes in particular. The usual treatment includes re-education sessions to improve joint amplitude and restore shoulder mobility. In persistent forms, intra-articular injection of cortisone is combined with distension of the capsule with a local anaesthetic under radiographic control. In some countries, subscapular nerve block (reversible anaesthesia) is used to improve pain. The combination of arthrodistension and subscapular nerve block has never been performed to accelerate the healing process. The aim of this study is to compare the performance of these two procedures together against the reference technique alone on time to improvement with the number of patients improved at one month according to the Constant score. This score is used to assess shoulder pain and function, with a significant improvement above eight points.

CD160 represents a new angiogenic factor as its specific engagement by an agonist monoclonal antibody directed against human CD160 reduced angiogenesis of endothelial cells with a distinct mechanism from current angiogenic therapies that target the VEGF/VEGF-R pathway. A soluble form of CD160, sCD160, has been found to be highly expressed in the vitreous and the sera of patients with severe diabetic retinopathies, and can now be dosed with help of an ELISA test. The investigators aim to evaluate the association between ischaemic retinopathies (patients with or without) and sCD160 concentrations in the vitreous, the aqueous humour and the serum.

Colorectal cancer is the third most common cancer in men, and the second most common in women. Screening for colorectal cancer is based on the search for blood in the stool using fecal immunochemical test (FIT). Occult bleeding is an indication for colonoscopy. In a FIT positive population, 60% of colonoscopies are negative, 34% diagnose an adenomatous lesion, and 6% a cancer. The identification of new biological markers could reduce the number of colonoscopies performed. Cancer cells release extracellular vesicles that contain proteins, mRNAs, DNA, which they can transfer to neighbouring or distant cells. The use of exosomal proteins as novel tumor markers looks very promising. We performed a pilot study comparing the levels of different exosomal proteins in 74 subjects which was recently accepted for publication in Journal of Clinical Laboratory Analysis. Comparison of results showed that only matrix metalloproteinase 14 (MMP14) was significantly higher in patients with colorectal cancer or adenoma than in people with normal colonoscopy. The primary objective of the current study is to determine the best cut-off value of MMP-14 for colorectal cancer screening and to evaluate the performance (Sensitivity, Specificity…) associated to this cut-off value. The secondary objective will be to determine the best cut-off value of MMP-14 for colorectal adenomas screening and to evaluate its performance. For this purpose, 650 patients, seen for diagnostic colonoscopy following a positive FIT test, will be included in the study. After blood collection and exosome isolation, MMP-14 will be measured using a quantitative test (enzyme-linked immunosorbent assay) and the results will be associated with colonoscopy results to determine the sensitivity, specificity, positive predictive value (PPV) and net present value (NPV).

Bipolar disorder and unipolar depressive disorder are two chronic mood disorders associated with a significant social impact, even during euthymic phases. Their differential diagnosis remains complex, particularly when bipolar disorder begins with a depressive episode. Identifying distinctive markers between these pathologies therefore represents a major clinical and economic challenge, as appropriate mood-stabilizing treatment can reduce healthcare costs and improve patients' functional outcomes. Among potential biomarkers, executive functions-and more specifically inhibition-have received particular attention. Inhibitory deficits are observed in both disorders, including during euthymic states, and also among first-degree relatives, suggesting their potential as cognitive and cerebral endophenotypes. These deficits may help explain the difficulties in emotion regulation and impulsivity frequently observed in mood disorders. Two components of inhibition are distinguished: 1. Behavioral inhibition, which refers to the ability to stop an ongoing response. 2. Interference control, which refers to the ability to resist distraction. These processes rely on partially distinct neural networks and operate at different stages of information processing. The few studies comparing these two components in bipolar disorder have shown contradictory results, and neuroimaging investigations have only partially explored these mechanisms, particularly their emotional dimension. It is, however, well established that patients with bipolar or depressive disorders show greater difficulties in executive tasks involving emotional stimuli than in purely cognitive tasks. The study is expected to reveal: * Differences in brain activation between euthymic bipolar and unipolar depressive patients in regions involved in inhibitory control, modulated by the emotional content of the task. * Distinct cognitive performance profiles according to pathology, reflecting specific alterations in inhibitory and interference processes. These findings should provide a better understanding of the differential neurocognitive bases of mood disorders. Identifying specific cognitive and neural profiles could contribute to more accurate differential diagnosis and to the personalization of therapeutic interventions, particularly through cognitive remediation strategies targeting executive and emotional deficits.

This study has two objectives. First, to evaluate the effectiveness of psychotherapy sessions based on self-concept and autobiographical memory in patients suffering from alcohol use disorders (AUD). Second, investigate the relationship between drinking identity and AUD. These objectives will be investigated according to a longitudinal design. In this study, the drinking identity is evaluated on its implicit dimension and on its explicit dimension. Levels of alcohol use and dependence are assessed by the amount and frequency of drinking, the duration of abstinence, and the intensity of AUD symptoms. These assessments consist three visits: on the day of inclusion, then at three months and six months after the first visit. The psychotherapy sessions consist of four individual sessions. They are inspired by the Social Identity Mapping in Addiction Recovery (SIM-AR) by Beckwith et al. (2019), combined with autobiographical reasoning exercises. Patients with an AUD, participants in the study, are recruited from the addiction department of the Etablissement Public de Santé Mentale de la Marne. To investigate the effects of individual psychotherapy sessions, two groups of patients are constituted randomly. The first group will have four psychotherapy sessions between the first visit and the second vist. The second group will not follow psychotherapy sessions but will benefit from the usual addiction treatments. The first hypothesis is that patients who have completed the psychotherapy sessions will have lower alcohol consumption (frequency, quantities, peaks) and symptoms of AUD (cravings, drinking refusal self-efficacy and feeling of recovery) than those who have not benefited from the program. The second hypothesis is that implicit and explicit levels of drinking identity will predict alcohol consumption (frequencies, quantities, peaks) and symptoms of dependence (cravings, drinking refusal self-efficacy and feeling of recovery) for all participants.

Bipolar disorder (BD) are common psychiatric disorders often misdiagnosed, leading to delayed treatment. Even during stable phases, individuals with bipolar disorder experience residual cognitive impairments that affect their social functioning and quality of life. This study aims to explore social cognition deficits (e.g., emotional processing, theory of mind, attribution bias) and their relationship with executive functions (e.g., flexibility, inhibition, working memory) and memory in bipolar disorder and major depressive disorder, ultimately seeking to improve understanding of their functional outcomes. Social cognition and executive functions in BD are both state- and trait-related. One recent meta-analysis demonstrated impairment in social cognitive domains for manic, depressive, and euthymic bipolar disorders' patients but it remains unclear whether these social cognitive deficits in BD are due to executive functions and/or other confounding effects. Few studies have investigated the interdependency between these cognitive impairments in these two affective disorders while a better understanding of the link between executive functions and social cognition seems crucial in order to better characterize the nature of patients' deficits and thus their caring.

Severe traumatic brain injuries are common and can lead to major long-term disability. Patients with severe brain injury often require admission to critical care. For relatives, this period is highly distressing: during and after an ICU stay, family members frequently experience anxiety, depression, and post-traumatic stress symptoms. In recent years, family involvement in critical care has been associated with better communication with the healthcare team and fewer psychological difficulties among relatives. In parallel, findings from neuroscience suggest that early multisensory stimulation (engaging the five senses) may help support brain recovery by promoting neuronal connections during the awakening phase. This study evaluates whether a standardized neurosensory stimulation program, delivered by trained relatives of brain-injured patients hospitalized in critical care, can reduce post-traumatic stress symptoms in those relatives. We hypothesize that involving relatives in a structured, supervised multisensory stimulation protocol during the patient's awakening phase (before transfer to rehabilitation) will decrease relatives' post-traumatic stress symptoms at 3 months after critical care discharge (or after the patient's death). We also expect potential secondary benefits on patients' awakening and recovery trajectory.

Chronic inflammatory pulmonary diseases, including asthma, chronic obstructive pulmonary disease (COPD), bronchiectasis, cystic fibrosis (CF), primary ciliary dyskinesia (PCD) and interstitial lung diseases (ILD) are characterised by lung inflammation and remodelling. Clinical, functional, microbiological, biological, pathological and prognostic features are highly variable and heterogeneous. Several phenotypes have been described within the same pathology, as similar phenotypic traits between different pathologies, or the coexistence of components of several diagnoses in the same patient, suggesting shared underlying mechanisms that could represent new therapeutic targets, beyond the initial medical diagnosis. The objectives of this prospective study are to analyze the phenotypic characteristics (clinical, demographic, biological, morphological, pathological, and microbiological characteristics) together with respiratory exposures and underlying mechanisms involving airway epithelium and inflammation processes in a cohort of patients diagnosed with asthma, COPD, bronchiectasis, CF, PCD and ILD.

Obtaining intravenous access is difficult in the pediatric population. Ultrasound-guidance allows real-time visualization of target veins which are invisible and impalpable. We hypothesize that the use of ultrasound by a trained nurse team would improve the success rate of peripheral intravenous catheter insertion in pediatric patients with difficult intravenous access, compared to palpation of the vein alone. For this study, when peripheral intravenous catheterization will be indicated in one of the participating pediatric services for an eligible patient, state-certified nurse investigators, trained in ultrasound guidance, will be contacted. After verification of eligibility criteria and all informed consents obtained, one of the investigators will randomize the patient in one of the 2 treatment groups under study: peripheral intravenous catheterization by visualization and palpation of the vein alone (standard of care) or by ultrasound guidance performed by a trained nurse. Several outcomes will be measured and compared between the 2 groups (e.g. successful insertion of intravenous catheter, pain, adverse events).

The peripartum period is the period between the last month of pregnancy and up to a year after childbirth. It can be considered a difficult time for women, as it is a period of transition during which vulnerability to psychiatric disorders and in particular to major depressive disorder (MDD) (Vesga-Lopez, Blanco, Olfson, Grant \& Hasin, 2008). Depression with peripartum onset (PPD) is characterised by the fact that the onset of symptoms may occur during pregnancy or within four weeks of delivery, but may also persist for up to 12 months after delivery (American Psychiatric Association, 2013). PPD affects 10 to 20% of women who have given birth (Tebeka et al. 2021). In addition, the psychological distress experienced by the mother during the peripartum period can disrupt interactions with her newborn (Lefkovics et al. 2014). Depression during this period can therefore have long-term consequences, not only for the women who suffer it, but also for their children (Gavin et al. 2005). The investigators now know that women with PPD have deficits in metacognition. Metacognition is the body of knowledge, processes and practices that enable individuals to control and evaluate their own cognitive activities, thereby enabling them to regulate them (Flavell, 1976). Patients with PPD therefore have difficulty identifying, controlling and evaluating their own cognitive activities. These deficits may also represent a risk factor for the development of PPD if they are present at an early stage (Diop et al. 2022). In patients with PPD, metacognitive therapies appear to be effective in reducing symptoms. In 2013, Bevan, Wittkowski and Wells conducted a pilot study to test the effects associated with metacognitive therapy in depression. This was the first published study to evaluate the effects of metacognitive therapy on patients with depression in the peripartum period. It shows promising results which it would be interesting to replicate, as this is a pilot study. A metacognitive training program for depression (D-MCT) was developed by Jelinek, Hauschildt, Moritz and Dubreucq in 2016, it is a brief group intervention that is easy to manage to participants. To date, no study has yet tested this specific program in patients with PPD, but it has been able to show its effectiveness in reducing the metacognitive deficits. In the light of the scientific literature, the aims of this study are, firstly, to demonstrate the efficacy of D-MCT therapy in subjects with post-partum depression. Secondly, to examine the effects of this therapy on mother-child interactions. The investigators make the following assumptions: * Women in the experimental group showed a greater reduction in depressive symptoms and an improvement in metacognitive functioning than those in the control group. * Women in the experimental group showed a reduction in depressive symptoms after therapy (v2) and maintenance of this improvement (v3). * Improvement in the quality of mother-child bonding for women who took part in the program compared with those in the control group. * Improvement in the quality of mother-child bonding after the program (v2 and v3) for women in the experimental group compared with when they entered the program.

Attachment is built primarily on the first interactions of the first 9 months of a baby's life. These first interactions and their effects of stress, pleasure and displeasure are retained to establish some of the baby's attachment behaviours and future relationships with others. Extreme prematurity strongly modify these first interactions between parents and child. Very preterm child is separated from his parents and is placed in a stressful, technical and potentially painful environment. Early interventions stimulate neuroplasticity and can positively affect the neurological development of very preterm infant. Tactile stimuli such as skin-to-skin contact and massages carried out by parents can be pleasant experiences that can support early interactions between parents and child.

Chronic kidney disease (CKD) affects more than 10% of the population worldwide and represents the second most important risk factor for preeclampsia, a life-threatening complication of pregnancy responsible for approximately 80,000 maternal and 500,000 perinatal deaths each year. Experimental studies have suggested a causal link between CKD, relative kynurenine deficiency during pregnancy, and preeclampsia development. Kynurenine, a tryptophan metabolite, plays a central role at the materno-fetal interface, supporting placental energy production, maternal-fetal immune tolerance, and placental perfusion. This study will prospectively assess and compare longitudinal kynurenine concentrations in pregnant women with and without CKD, and evaluate their associations with maternal and fetal outcomes.

Peri-medullary anesthesia is the preferred anesthetic technique for Caesarean surgery. Compared with general anesthesia, it reduces maternal and fetal morbidity and mortality, as well as postoperative pain. However, this technique exposes the patient to the adverse effects of peri-medullary morphine, particularly the risk of postoperative urinary retention. Urinary retention during the first 72 hours after Caesarean section affects around 33% of parturients. This is a particularly debilitating event for parturients, exposing them to the risk of further urinary catheterization, increased theoretical risk of urinary tract infection, traumatic urethral injury, hindered accelerated rehabilitation and altered maternal satisfaction. Several studies have demonstrated the benefits of adding magnesium sulfate to epidural anesthesia for Caesarean sections, notably by reducing postoperative pain. Magnesium sulfate may also have a facilitating effect on postoperative micturition, thanks to its sympathicolytic effect. This hypothesis is supported by a retrospective study carried out in our maternity hospital, which showed a 15% reduction in post-Caesarean urinary retention when women were given magnesium sulfate in addition to the drugs traditionally used for epidurals. This little-known property needs to be clarified

Short description of the protocol intended for the lay public. Include a brief statement of the study hypothesis (Limit : 5000 characters) The sickle cells anemia is a monogenic disease linked to the presence of Hemoglobin S due to a mutation in the Hemoglobin Beta chain. The lack of circulating oxygen induces a polymerization of the Hemoglobin S which change the red cell conformation into sickle. Those cells interact and causes vaso-occlusive crisis (CVO). The MEOPA is a medical gas used as an antalgic and a sedative especially in sickle cells disease patients. The nitrous oxide, oxide the cobalt ion in the vitamin B12 which inactivate it irreversibly creating a functional deficiency. During the metabolism of vitamin B12, homocysteine is transformed in methionine which is used in to form the myelin sheath and helped in producing DNA. Numerous studies already shown that the longer the exposition to MEOPA is the greater the functional deficiency of vitamin B12 occur. A few studies shown a symptomatic deficiency of vitamin B12 due to the exposition of MEOPA in sickle cells patient but there is no explanation on the necessary amount of exposure or if some patients are more at risk. When there is a deficiency of vitamin B12 the symptoms can go from a simple orthostatic hypotension to a combined spinal sclerosis. The participation to the study will be proposed to every patient hospitalized for a CVO in the follow up of the emergency room visit or directly in pediatric reanimation. During a usual blood test, a small amount of blood (4mL) will be collected in addition to dose the Vitamin B12, the vitamin B9, the homocysteine, and the methionine. A small amount of urine will also be collected to dose the methylmalonic acid, all those elements are a part of the metabolism of B12 vitamin. The same sample will be taken on the day of departure of the hospital. During the hospitalization the pain management, a daily neurological exam, and the exposition to the MEOPA will be assessed meticulously. An appointment will take place at 7 days and at one month after the hospital departure to evaluate the possible neurological defect. Each patient can only be included once.

In 2018, the World Health Organization (WHO) counted no less than 15 million preterm births each year worldwide, or more than one in ten children. In recent years, the number of newborns surviving preterm birth has gradually increased due to advances in neonatal medicine. However, these rescues are not without consequences. Indeed, to do so, the child is separated from his parents, placed in a stressful, technical and potentially painful environment. This early separation is compounded by medical co-morbidities and sedations that compromise the child's physiology and availability to interact. Extreme prematurity also disrupts the early interactions between the child and his parents, and eventually the relationships with others. Thus, more than 35% of children born prematurely show insecure attachment behavior in their relationships with others. Moreover, premature births are accompanied by numerous somatic, cognitive and social cognitive difficulties. At school age, these children present more learning, social-emotional and behavioral problems. The greater the degree of prematurity, the more marked these difficulties are. They would be associated with an executive and social cognition deficit, inherent to a globally altered cerebral development, in particular the frontal subcortical cerebral regions. On the parents' side, premature birth is also fraught with consequences. Indeed, the idea of an idealized post-natal period gives way to an anxious, even traumatic experience. Notions of guilt are often expressed, as well as major anxiety about the child's survival and "parenting skills". A higher prevalence of signs of parental anxiety, postnatal depression and post-traumatic stress disorder is observed in mothers of premature infants, even up to 18 months after birth. These psychological states influence the parents' ability to interact with their newborn, as well as the content of these interactions. Finally, both parents and newborns see, for different reasons, their ability to interact and to reassure themselves profoundly disrupted by premature birth. Even if since 2010, prematurity has been identified as a "public health problem" by the WHO, studies on the subject still have limitations. Indeed, if we estimate that the prevalence of anxiety and/or depression signs in mothers of premature babies is on average three times higher than in mothers of full-term babies; what about fathers? It seems fundamental to improve our knowledge of the anxious and depressive symptoms that fathers and mothers of premature babies may display, with the aim of providing comprehensive and multidisciplinary care for families in neonatal intensive care units. Similarly, the exact impact of an increase in parental anxious depressive symptomatology on the precursors of cognitive and social cognitive development is not known. Since the environment and stimulation are fundamental to the child's development, what happens when one or both parents have their interaction modified by anxious-depressive symptomatology? Indeed, the rare studies publishing data on the subject are carried out on populations of parents of non-premature children, often non-French-speaking and above all with tools that are not available to French-speaking practitioners in charge of the early detection of developmental difficulties in premature children. Today, it seems necessary to provide data concerning the development of precursors to cognitive and social cognitive development in preterm infants, and to better understand the extent of its interaction with the anxious depressive symptomatology of the mother and father. The investigators therefore formulate the following hypotheses: * Anxious depressive symptomatology, such as signs of parental anxiety, postnatal depression, and posttraumatic stress disorder, would be higher in mothers and fathers of preterm infants than in mothers and fathers of full-term infants at 7 ± 1 weeks after birth. * The level of development of the precursors to cognitive and social cognitive development would be lower in children whose parents present an exacerbated anxious depressive symptomatology.

The obstructive sleep apnea syndrome (OSAS) involves recurrent sleep-related upper airways (UA) collapse. UA mechanical properties and neural control are altered, imposing a mechanical load on inspiration. UA collapse does not occur during wakefulness, hence arousal-dependent compensation. Experimental inspiratory loading in normal subjects elicits respiratory-related cortical activity during wakefulness. The objective of this study is to test whether awake OSAS patients would exhibit a similar cortical activity. Whether or not such cortical compensatory mechanisms have cognitive consequences would be also analyze.

Stroke represents a major cause of morbidity and mortality despite significant progress in recent decades. In individuals under the age of 65, the etiologies of ischemic stroke (IS) are diverse, and management is well-established. Antiphospholipid syndrome (APS) accounts for 10 to 20% of the causes of stroke in this population. In elderly individuals, APS is not systematically investigated due to the predominance of embolic, atherosclerotic, and small vessel disease causes. However, delayed discovery of APS is not uncommon and is more frequently associated with the occurrence of arterial thrombosis. Moreover, the management of APS involves several challenges given the risk of recurrence of thrombosis and the potential association with conventional cardiovascular risk factors. The antithrombotic treatment consists of lifelong anticoagulation, excluding direct oral anticoagulants (DOACs) due to the risk of thrombotic recurrence. The main objective of the study will be to assess the prevalence of antibodies useful for the diagnosis of APS (Sapporo criteria) in individuals aged 65 or older hospitalized for an ischemic stroke (IS) or transient ischemic attack (TIA). Furthermore, the classification of APS is likely to evolve in the coming years with the inclusion of new clinically relevant antibodies (anti-phosphatidylserine and anti-phosphatidylethanolamine) because of their strong association with the occurrence of thrombosis. Even though they are often associated with circulating anticoagulants, they are also found in 10% of APS cases negative for other antibodies. Patient inclusion in the study should occur during the acute phase of the stroke, before the initiation of anticoagulant treatment. Thus, after verifying the inclusion and exclusion criteria, patients will be informed and must sign the informed consent form if they agree to participate. After inclusion, the research procedure will be as follows: * Conduct a unique immunological biological assessment with: * Part performed as part of standard care: circulating anticoagulants, anti-cardiolipin antibodies, and anti-β2-glycoprotein type 1. * Part performed specifically for the study (3.5 mL of additional blood): anti-phosphatidylserine and anti-phosphatidylethanolamine antibodies. The search for these antibodies will be performed using the 7mL dry tube collected for anti-cardiolipin and anti-β2-glycoprotein type 1 antibody testing. * If the diagnostic sample is positive for any of these antibodies, a follow-up at 3 months is recommended and will be performed as part of standard care to confirm the APS diagnosis. * Data collection will include patient details, stroke/TIA details, biological data, and follow-up. As part of routine follow-up, patients will be seen in a neurological consultation at 6 months. Clinical and biological data will be reviewed at the end of the study by two doctors (a neurologist and an internist) to confirm or exclude the APS diagnosis and its contribution to the neurological condition. An internal medicine follow-up will be initiated for patients with confirmed APS, and an appropriate treatment will be proposed.

Chronic kidney disease (CKD) results from the progressive and irreversible destruction of the kidneys. As of December 31, 2018, there were 89,692 people in France undergoing replacement therapy, including 49,271 (55%) on dialysis and 40,421 (45%) with a functioning kidney transplant. The primary treatment modality is currently hemodialysis. It is known to activate the coagulation cascade and blood platelets, leading to thrombus formation and premature termination of the hemodialysis session. This loss of circuitry results in a decrease in session time leading to an insufficient dialysis dose and blood loss in patients who are already often anemic due to their chronic renal failure. To avoid this complication, current recommendations recommend the use of unfractionated heparin (UFH) or low molecular weight heparin (LMWH) during the hemodialysis session at the cost of an obligatory hemorrhagic risk due to the systemic administration of heparin. However, this risk of bleeding is already very high, due to platelet dysfunction, a direct consequence of uremic toxin impregnation in these patients. In addition, this hemodialysis population is frequently exposed to antiplatelet agents and anticoagulants (heparin or VKA), which aggravate the hemorrhagic risk inherent to renal pathology. In this context, bioactive membranes such as the HeprAN™ membrane, coated in heparin, have been developed to minimize or even eliminate the need for anticoagulation during sessions in chronic hemodialysis patients. Several studies with this membrane have demonstrated the absence of the need for additional heparin in populations with no particular bleeding risk and in populations at risk of bleeding: post-operative (HepZero study), patients on VKA. The HYDROLINK™ membrane offers the same anticoagulant prospects as the HeprAN™ membrane, but its mode of action involves the use of a copolymer with hydrophilic properties, making it possible to avoid the presence of heparin. This membrane would have an influence on platelet aggregation. It would also make it possible to avoid the risk of heparin-induced thrombocytopenia (HIT) by completely excluding heparin from the dialysis session

The purpose of this study is to investigate the development of social cognition skills in pediatric epilepsy compared to healthy children. There are evidences indicating that children with epilepsy have executive dysfunctions and language problems. Executive functions refer to multiple cognitive processes that contribute to human higher order abilities, such as purposeful and future-orientated behavior. Moreover, the literature regarding development of non epileptic children, with ordinary development indicates that executive functions and language are linked to the emergence of social cognition. Then, the investigators asked if children with epilepsy, as they commonly present executive dysfunctions, would show an atypical development of social cognition. Children with epilepsy and a control group of healthy volunteers will be compared to identify relationships between executive functions, language and social cognition.

This study is a prospective, observational, bicentric study, evaluating the validity and reliability of a French version of the mPCOSQ questionnaire (mPCOSQ-F), used to assess health-related quality of life (HRQOL) in women with polycystic ovary syndrome. The first stage of the study consisted in translating the questionnaire from English to French. Patients agreeing to take part in the study will complete the mPCOSQ-F and the SF-36 (generic HRQOL questionnaire). After 1 to 2 weeks, patients will receive the mPCOSQ-F and complete it again.
