Pupillometry vs. BPS (Behavioral Pain Scale) for Analgesia Management in Inpatient Intensive Care Unit Patients on Invasive Mechanical Ventilation

Patients admitted to the intensive care unit (ICU) and receiving invasive mechanical ventilation (IMV) frequently require sedation and analgesia to ensure their comfort, prevent pain associated with invasive procedures, and minimize complications related to agitation. Appropriate analgesia management is essential to ensure patient comfort while minimizing the consequences of excessive opioid exposure, including delirium, prolonged mechanical ventilation, extended ICU stays, and the risk of post-ICU syndrome (PICS). While sedation assessment relies on validated tools such as the RASS score, pain assessment in non-communicative patients remains more complex. In practice, it relies primarily on behavioral scales such as the Behavioral Pain Scale (BPS), the only internationally validated scale that has been translated into French and is recommended for use in intensive care. However, these scales have certain limitations, particularly in deeply sedated patients or when motor expression is impaired. Thus, over the past few years, automated pupillometry has been developed to assess pain through the pupillary dilation reflex (PDR), which is an autonomic physiological response to nociception. Indeed, pupillometry allows for the quantitative measurement of the PDR induced by standardized, noninvasive nociceptive stimulation. This measurement yields the Pupillary Pain Index (PPI), which serves as an objective, reproducible, and observer-independent indicator of nociception. Measuring the PPI could enable earlier and more individualized adjustment of analgesia, leading to a reduction in painful episodes and opioid exposure. In this context, this randomized study aims to compare, in patients on mechanical ventilation with deep sedation and analgesia (RASS -4/-5), a pain monitoring strategy guided by pupillometry with standard care based on the BPS. The objective is to evaluate the impact of this strategy on the frequency of pain event detection and on complications associated with opioid use in the intensive care unit

Chorioretinal Imaging, Vascular Biomarkers, and Ultra-Trail: A Pilot Study

Retinal and choroidal microcirculation is a relevant biomarker of systemic vascular health and lies at the heart of eye-heart interactions. Noninvasive retinal imaging, particularly OCT angiography (OCT-A), now makes it possible to examine retinal and choroidal microvascularization in vivo and to study its relationship with systemic cardiovascular and neurovascular mechanisms. Ultra-endurance activities, such as ultra-trail races, induce significant systemic hemodynamic changes, including dehydration, variations in perfusion pressure, prolonged sympathetic activation, and redistribution of blood flow. These physiological adaptations could lead to acute and reversible changes in retinal and choroidal vascular parameters as measured by retinophotography and OCT angiography. Several studies suggest that intense physical exercise may be accompanied by significant changes in retinal and choroidal microvascular perfusion. In particular, a significant decrease in the vascular density of the superficial retinal plexus has been observed following intense exercise in a healthy population, suggesting a transient change in retinal microcirculation. Similarly, following a marathon, a decrease in the retinal vascular density index (RVDI) has been reported, likely related to exercise-induced vasoconstriction and a transient reduction in retinal blood flow. This decrease may also be exacerbated by the drop in systemic blood pressure and the relative dehydration observed after the race. More broadly, intense endurance exercise is accompanied by cardiovascular and neurohormonal adaptations, particularly through activation of the renin-angiotensin-aldosterone system, which may modulate ocular perfusion. Scott et al. demonstrated, following a 160-km ultramarathon, significant alterations in left ventricular function and a major elevation in NT-pro-BNP, indicating systemic cardiovascular stress that was markedly greater than that observed after a standard marathon. Furthermore, a multi-omics study conducted during the Ultra-Trail du Mont-Blanc (171 km) revealed systemic oxidative stress, marked inflammation with elevated IL-6 levels, and profound metabolic changes affecting red blood cells-mechanisms recognized as being involved in microvascular dysfunction. However, these variations primarily reflect functional changes in perfusion related to hemodynamic status and autonomic tone, rather than true structural microvascular remodeling or angiogenesis. Metrics derived from OCT angiography, such as vascular density or perfusion density, are in fact sensitive to systemic variations in circulating volume, perfusion pressure, and the quality of the acquired signal. In this context, the effects of ultra-endurance exercise on the eye remain poorly characterized. Research in this area is necessary to better understand the acute physiological adaptations of ocular microcirculation and to highlight the value of retinal imaging as a tool for cardiovascular research and prevention within an integrated eye-heart approach.

Single-center Study of Gustation in Idiopathic Parkinson's Disease and Lewy Body Disease Using Gustatory Evoked Potential Analysis

The aim of the PI-PEG study is to explore the taste functions of the following 3 groups of participants: * healthy volunteers * patients with early Parkinson's disease * patients with incipient Lewy body disease. To this end, the results obtained from taste evoked potentials in each of the 3 groups of participants will be compared with each other and with different nutritional, motor and cognitive data. This study could reveal a difference in cortical processing of gustatory sensory information between patients who have had idiopathic Parkinson's disease progressing for 3 years or less, and patients who have had Lewy body disease progressing for 3 years or less. Indeed, a modification of taste evoked potentials (in terms of latencies) proportional to the degree of cerebral degeneration could be observed.

Oncology, Undernutrition and Sensoriality: Links, Mechanisms and Levers for Action

Cancers of the upper aerodigestive tract account for around 4% of all malignant tumours worldwide. Colon and liver cancer are the most common digestive cancers. The epidemiology of liver cancer is changing, and the number of deaths from liver cancer has increased by 25% worldwide. In France, around 19,000 cancers of the upper aerodigestive tract and 88,000 new cases of digestive cancer are diagnosed each year (colon cancer remains the most common). Patients with these two types of cancer are at particularly high risk of undernutrition. In cancer patients, changes in diet may result from constraints linked to the cancer or possible after-effects, but also from personal choices (for example, adopting a healthier diet). Cancer and its treatment lead to changes such as increased nutritional requirements and hypercatabolism, or sensory changes (taste and smell), reducing pleasure and food intake. These problems will impair quality of life and intensify undernutrition, a major problem in the management of the disease since it increases the risk of complications, therapeutic failure and mortality. It is estimated that 10-20% of deaths in cancer patients are attributable to the consequences of undernutrition rather than to the disease itself. In the VICAN study, 41% of patients changed their diet after diagnosis: 29% because of changes in taste and 82% to have a healthier diet. These changes were associated with the treatment received, the presence of sequelae and anxiety. Taste and smell disorders are common in different types of cancer (any solid or haematological type) and treatments (chemotherapy, radiotherapy and surgery. The mechanisms involved in sensory changes are not fully understood, especially in cancer, and with different types and treatments. Several hypotheses have been proposed: altered expression of enzymes of the oral sphere, altered expression of sensory receptors, saliva composition and function, and impact of the oral microbiota. The early identification of undesirable effects linked to nutrition, and the early or anticipated diagnosis of undernutrition are important issues in the management of cancer patients. The pleasure (or displeasure) produced by food guides desire and eating behaviour. The mechanisms involved are linked to hedonic sensations: conditioned satiety, specific sensory satiety, negative alliesthesia and the reward system (hedonic system). The latter is influenced by the environment and can be consciously controlled, with several dimensions: liking (the patient likes or dislikes a given food) and wanting (evaluates the desire to consume a given food at a given moment). All these parameters, together with sensory and dietary learning throughout life (habits, beliefs and constraints), influence food preferences and therefore eating behaviour. Individual sensitivities and the personal history of the disease (treatment and care pathway, sequelae, presence of co-morbidities, etc.) must therefore be taken into account when setting up preventive actions for cancer patients. It seems important to explore these factors, the experience of patients and the consequences for eating behaviour in daily life, in order to improve support and communication with healthcare professionals, as well as prevention and early detection of undernutrition. It would be interesting to conduct more in-depth studies on nutritional status, quality of life and changes in taste and smell, which in most studies have been considered separately.

Exploratory Study of the Efficacy of HuMoSCs (Human Monocyte-derived Suppressor Cells) on Glandular Involvement in Sjögren's Syndrome

Sjögren's syndrome is an autoimmune disease. Dry syndrome is a key feature of this condition, almost always leading to dryness of the mouth and eyes. It manifests as a decrease in the production of saliva and tears, causing discomfort for patients. This chronic dryness contributes to oral and ocular conditions. It is caused by lymphocytic infiltration of the exocrine glands, leading to their inflammation and subsequent fibrosis, which results in a decrease in fluid production by these glands. This chronic inflammation causes fatigue in the patient. Furthermore, in 30 to 60% of cases, Sjögren's syndrome may involve extra-glandular involvement, most commonly affecting the joints, but also involving the lungs, nervous system, and kidneys. Additionally, patients with thisdisease have a higher risk of developing lymphoma compared to unaffected individuals. The current treatment for Sjögren's syndrome is the same as that for dry eye syndrome; it is primarily symptomatic, involving lifestyle and dietary changes, the use of eye drops or oral lubricants, and medication to stimulate saliva production. To date, there is no medication available to treat Sjögren's syndrome and thus the cause of dry eye syndrome. In our laboratory (INSERM 1098, UMR Right), we have developed cells that suppress the immune system (immunosuppressive cells) derived from human monocytes cultured ex vivo using a patented process called HuMoSC (Human Monocyte -derived Suppressor Cells). These cells possess strong immunosuppressive capacity, already demonstrated in vitro and in vivo in mouse models. The aim of this study is to evaluate whether HuMoSCs can reduce the accumulation of immune cells and thereby decrease chronic inflammation and, in the longer term, limit the development of fibrosis (hardening with tissue destruction and scarring) in the salivary glands. Biopsy of the accessory salivary glands is already part of the diagnostic process for Sjögren's syndrome. During this biopsy, additional accessory salivary glands will be collected and sent to the laboratory for this study. These glands will be cultured in the presence of HuMoSC supernatant, and the impact of this treatment will be analyzed.

Study of the Hypothalamic Microglial Response as a Function of a Meal's Lipid Content in Humans. A Single-center Prospective Cohort Study in Healthy Male Subjects

Obesity and its complications represent a growing public health problem in our society. A better understanding of the biological mechanisms involved in regulating food intake-and, more broadly, energy metabolism-should lead to improved management of this condition. Recent studies have shown that eating a single meal can rapidly trigger the activation of the immune system. This leads to a postprandial, systemic, and transient inflammatory response (Emerson SR, Adv Nutr 2017). It is found in both healthy and obese individuals. It has also been observed in rodents, enabling preclinical studies to better understand the phenomenon. This postprandial inflammation is characterized by the activation of macrophages in the gastrointestinal tract and by elevated levels of circulating pro-inflammatory markers. At the cellular level, nutrients activate an intracellular molecular sensor called the inflammasome, which is a multiprotein complex formed by the oligomerization of proteins including NLRP3 (Nod-like receptors pyrin domain-containing 3) and ASC (Apoptosis-associated Speck-like protein containing a CARD domain). This sensor activates caspase 1, an enzyme that converts pro-interleukin 1β (pro-IL-1β) into its mature and active form, IL-1β. This molecular mechanism converts the nutritional signal into an immune response. Under physiological conditions, this acute response appears to have beneficial effects on the body. Indeed, it plays a positive role in blood glucose control by stimulating insulin secretion and glucose utilization (Dror, Nat Immunol 2017). However, in the context of chronic overeating and excessive consumption of saturated fats and simple sugars, this systemic inflammation becomes harmful, promoting adipocyte hypertrophy, insulin resistance, hepatic steatosis, and vascular damage (Hotamisligil, Nature 2017). In mice, our team recently demonstrated the existence of a postprandial inflammatory response in the central nervous system (Cansell, Glia 2021). This response occurs specifically in the hypothalamus, a brain structure involved in regulating food intake and controlling energy metabolism. It is characterized by microglial reactivity visible as early as 3 hours after the start of the postprandial phase. This postprandial microglial activation occurs after the ingestion of a high-fat meal, whereas it is rarely or never observed after the ingestion of a standard balanced meal. It is characterized by a morphological change in hypothalamic microglia, including an increase in the length of microglial processes and their branching. This gliosis is associated with increased expression of IL-1β in microglial cells. Thus, the postprandial gliosis observed 3 hours after a high-fat meal is inflammatory. Using a targeted genetic approach that allows for the ablation of the inflammasome in microglial cells, the team demonstrates that postprandial gliosis exerts a satiating effect, limiting subsequent food intake following a high-calorie, high-fat meal. Thus, microglial inflammation appears to be an additional component in the body's arsenal of adaptive homeostatic responses aimed at limiting energy intake. Our clinical project will involve translating our basic findings in mice to humans. This will involve investigating postprandial hypothalamic gliosis in the human brain following a standard meal or a high-fat meal. The initial studies will be conducted exclusively in healthy male subjects to avoid the influence of the hormonal cycle on the hypothalamic response. The impact of physiological aging on the hypothalamic microglial inflammatory response will also be taken into account.

Exploratory Functional Assessment After Lower Limb Amputation: Locomotion, Balance, Energy Performance and Strategies for Adapting to Orthopaedic Devices

The general aim of this exploratory study is therefore to investigate and quantify the functional capacities of patients with lower limb amputations (transtibial and transfemoral), with no change in their management, and to describe any changes in these capacities. The volunteers included in this study will be testing new equipment, all of which will be CE-marked, and will therefore meet all the safety and performance conditions required for use by these patients (equipment that is likely to be prescribed as standard). These devices could benefit from current technological advances that could improve these patients' functional abilities. They will be chosen and adapted according to the volunteer's activity and current equipment. This is a local project of the CHU Dijon Bourgogne which will take place on the Technological Investigation Platform located at the Centre de Rééducation et de Réadaptation of the CHU Dijon Bourgogne. A maximum of 100 patients will take part in the study, divided into two sub-groups of between 5 and 50 patients, depending on the type of brace worn and the level of amputation. After the inclusion visit, each volunteer will undergo 2 assessment visits (the order of assessment of the devices will depend on randomisation) separated by 3 to 6 weeks. Follow-up is for a maximum of 14 weeks.

Effect of Weekly GLP1 Agonist Treatment in "Double Diabetes"

Between 16% and 22% of type 1 diabetic patients present a clinical and biological profile of insulin resistance favored by a family history of type 2 diabetes or metabolic syndrome. They constitute a group of patients with "double diabetes" since they have both true type 1 diabetes and inherited insulin resistance, typical of type 2 diabetes. For several years, GLP1 agonists have been successfully used in the treatment of type 2 diabetes, leading to very significant improvements in glycemic control and weight loss. Because of the insulin-sensitizing power of GLP1 agonists, the investigators hypothesize that they could reduce insulin resistance in patients with "double diabetes" and thus improve their glycemic control. The investigators propose to use in this study semaglutide, the most recent and most potent GLP1 agonist (superiority demonstrated compared to exenatide LP and dulaglutide) and administered as a weekly subcutaneous injection (in contrast to liraglutide administered daily).

Association Between Circulating BDNF Levels and Cardioembolic Strokes in Patients Treated for Ischemic Stroke

Atrial fibrillation (AF) is associated with serious complications, including embolic strokes, heart failure, and mortality. Disruption of normal blood flow in the atrium, particularly in the context of an endocardium predisposed to thrombosis, increases the risk of thrombus formation. Once dislodged from the atrial cavity and traveling to the cerebral arteries, these thrombi can cause a cardioembolic stroke. The main risk factors for atrial cardiomyopathy (ACM) and AF are metabolic syndrome and aging. ACM is a condition that is difficult to diagnose because it is not clearly defined, except through histological analysis. Guided by the results of our experimental approaches, the investigators aim to address this challenge by examining ACM through the lens of one of its complications: cardioembolic stroke. BDNF (Brain-Derived Neurotrophic Factor) is a neurotrophic factor involved in inflammatory and metabolic processes that may play a key role in the development of these complications. This study explores the association between circulating levels of BDNF and the morphological and metabolic characteristics of ACM, as assessed by cardiac and brain imaging studies

Aspirin in Acute Pneumonia in the Elderly: a Multicenter, Double-blind, Randomized, Placebo-controlled Trial.

Acute pneumonia is a very common disease, and one of the leading causes of hospitalization and death in France. Almost a century after the discovery of penicillin, no major breakthrough has significantly reduced pneumonia-related mortality. While the choice of an appropriate antibiotic is decisive in the acute phase of the disease, the longer-term prognosis depends essentially on the worsening of other underlying pathologies, particularly in the elderly. In cured patients, excess mortality persists several months after the episode of pneumonia, due in particular to the onset of cardiovascular complications. Recent scientific literature shows an association between the prescription of cardio-protective drugs and survival after pneumonia. Older patients are usually excluded from interventional studies, so there are no specific recommendations for these patients at high risk of both acute pneumonia and cardiovascular events. The aim of this study is to assess the efficacy of low-dose aspirin therapy after pneumonia in preventing cardiovascular events in the elderly. The main objective is therefore to evaluate the impact of aspirin at a dose of 100mg per day on all-cause mortality at 90 days in patients over 75 years of age hospitalized for pneumonia.

Single-center Prospective Longitudinal Study of Taste in Patients With Cognitive Disorders at Different Stages of Severity (Isolated Cognitive Complaint, Minor or Major Neurocognitive Alzheimer-type Disorders) by Analysis of Gustatory Evoked Potentials

The aim of the MAPEG 2 study is to explore gustatory function and to follow its evolution in the 4 following groups of participants: * Healthy subjects * Participants with isolated cognitive complaint * Participants with minor neurocognitive disorder * Participants with mild and moderate Alzheimer-type major neurocognitive disorders For this purpose, we want to compare the results of the following tests: * Subjective taste tests (tasting solutions, answering food preference questionnaires), * Gustatory evoked potential (GEP) parameters, recorded by electrodes placed on the scalp, * And nutritional parameters (hormones of food intake by blood test, measurement of the global body composition). Identifying and following the evolution of early taste disorders in case of cognitive disorders could improve the diagnosis of Alzheimer\'s disease in two ways: * To allow an early diagnosis of Alzheimer\'s disease, and thus improve its management, * To define groups of subjects at risk of developing Alzheimer\'s disease in later years.

A Study of the Value of Trio Genome Sequencing in the Etiological Evaluation of Early-Onset and/or Atypical Psychiatric Disorders Without Intellectual Disability or Congenital Anomalies

According to the World Health Organization, one in eight people worldwide has a mental disorder, defined as a significant impairment in thinking, emotional regulation, or behavior. These disorders are classified according to the DSM-5. These psychiatric disorders may be atypical in terms of their age of onset, course of the illness, unusual response to treatment, or classification (significant impact but classified as a "disorder not otherwise specified" by the DSM-5). These disorders can occur sporadically or run in families. In France, there are no genetic testing recommendations for these patients. A CGH-array analysis may be ordered as part of patient care, as may testing for Fragile X syndrome, depending on the clinical context. The main hypothesis is that atypical psychiatric disorders result from multifactorial inheritance, involving a combination of common genetic variations and environmental factors. Pangenomic association studies and twin studies have already demonstrated heritability in these psychiatric disorders. It has now been shown that some neurodevelopmental disorders (NDDs) and psychiatric disorders-such as autism spectrum disorders or schizophrenia, for which similar hypotheses were proposed in the past-may result from monogenic inheritance. Furthermore, preliminary indications now allow for the prescription of genome sequencing on the platforms of the France Genomic Medicine Plan 2025. To date, no study has evaluated the role of high-throughput sequencing in an etiological approach to atypical, non-syndromic psychiatric disorders. Through this study, we aim to assess whether genome sequencing (GS) could be relevant for atypical, non-syndromic psychiatric disorders, which would be the case if it leads to an etiological diagnosis in at least 12% of cases. The establishment of the GénoPsy network (Centers of Excellence for Behavioral Disorders in Developmental Disorders) creates an environment that is highly conducive to the development of this project.

Prevalence of Cardiac Thrombi in Cardiac Amyloidosis

Cardiac amyloidosis (CA) is an infiltrative disease characterized by deposits of amyloid proteins of genetic or acquired origin (often in elderly patients), leading to heart failure and arrhythmias. More than 98% of currently diagnosed cases of cardiac amyloidosis result from fibrils composed of monoclonal immunoglobulin light chains (AL) or transthyretin (ATTR), in its hereditary (ATTRv) or acquired (ATTRwt) form. Its prevalence is rising sharply due to an aging population and improved diagnostic techniques. Atrial fibrillation is responsible, in particular, for heart failure, arrhythmias, conduction disorders, and ischemic strokes, and is associated with significant morbidity and mortality. These patients have a much higher-than-normal risk of stroke because they are in a procoagulant state in the left atrium, even in the absence of atrial fibrillation. Intracardiac thrombi (ICTs) are present in 28% of patients with AC requiring cardioversion, compared with 2.5% of patients without AC, 50% of whom are on anticoagulants. It has also been shown that the CHA2DS2-VASc score is not effective in predicting thromboembolic risk, and that direct oral anticoagulants (DOACs) are as effective as vitamin K antagonists (VKAs) in preventing embolisms. The prevalence and factors associated with the development of intracardiac thrombi in patients with cardiac amyloidosis are unknown, as the available retrospective studies focused only on selected high-risk patients. Furthermore, tafamidis is now available to stabilize the course of cardiac amyloidosis and improve prognosis, but its effect on thromboembolic risk remains unknown.

A Study Using Human Abdominal Adipose Tissue Biopsies to Characterize the Role of Endocannabinoids in Adipocyte Differentiation

Abdominal obesity and type 2 diabetes are associated with hyperactivation of the endocannabinoid system. Several animal and human studies indicate that circulating endocannabinoid levels correlate with body fat mass. Thus, adipose tissue, which possesses the enzymatic machinery of the endocannabinoid system, may be the primary producer of plasma endocannabinoids. Today, it is well established that stimulation of the endocannabinoid system, through the activation of cannabinoid receptor 1 (CB1R) located in the brain, leads to increased food intake and weight gain. Furthermore, peripheral CB1R present in adipose tissue are also directly involved in energy storage processes. Indeed, activation of the endocannabinoid system in adipose tissue is associated with stimulation of pathways leading to the uptake of carbohydrates and fatty acids, as well as their storage in the form of triglycerides. Adipose tissue consists primarily of mature adipocytes, and activation of the endocannabinoid system appears to play a key role in increasing fat mass by promoting the hypertrophy of these adipocytes through the stimulation of lipogenesis. However, the vascular stromal fraction also contains stem cells capable of generating new adipocytes, and an autocrine action of endocannabinoids on progenitor cells could also contribute to its expansion by promoting hyperplasia. That is why, in this project, the investigators aim to study the impact of endocannabinoids on the differentiation of stem cells from the stromal-vascular fraction into adipocytes. In particular, the investigators will seek to compare the impact of endocannabinoids on the differentiation capacity of stem cells derived from adipose tissue collected from patients with obesity, with or without diabetes, compared to controls. These data, combined with those obtained in parallel in mice, could help determine whether adipose tissue (visceral and/or subcutaneous) is a priority target for the development of CB1R-blocking molecules (such as rimonabant) with exclusively peripheral action (which do not cross the blood-brain barrier to avoid psychiatric side effects) for the treatment of metabolic obesity and type 2 diabetes.

The Potential of Mesenchymal Stromal Stem Cells to Correct Immune and Metabolic Dysfunctions in Circulating Immune Cells During Sepsis: An Ex Vivo Pilot Study.

Sepsis is a life-threatening organ dysfunction caused by the host's dysregulated immune response to infection. It represents a major global public health challenge. A state of post-septic compensatory immunosuppression may contribute to excess mortality by promoting secondary infections, thereby prolonging the stay in the intensive care unit and increasing the risk of death. New therapeutic strategies to complement antimicrobial treatments-which may correct sepsis-induced functional alterations in immune cells (such as endotoxin tolerance and reduced HLA-DR expression), partly mediated by metabolic abnormalities-are currently being investigated. Among these, mesenchymal stromal cells (MSCs) appear particularly promising. They are capable of reprogramming immune cells by redirecting certain metabolic pathways, notably improving mitochondrial function. MSCs generally have an anti-inflammatory effect in preclinical models of infection, particularly in the early phase of severe ventilated pneumonia, as illustrated by the animal model we have developed, and preliminary trials are currently underway in humans. The ability of CSMs to correct sepsis-induced immunosuppression has not yet been explored. Nevertheless, CSMs possess the ability to communicate with the inflammatory microenvironment in which they are found, conferring plasticity to their response. We hypothesize that CSMs could correct certain immune and metabolic dysfunctions in circulating immune cells from patients with sepsis meeting severity criteria who are admitted to the intensive care unit. Furthermore, priming (or prior stimulation) of CSMs could enable a more precise and personalized therapeutic approach, with the possibility of directing CSMs toward a pro-inflammatory (CSM1) or anti-inflammatory (CSM2) phenotype through prior incubation with specific agonists (LPS; IFN-γ/TNF, respectively) before their administration. Depending on the patient's immune status (pro-inflammatory or anti-inflammatory phase), such a personalized approach would optimize treatment with CSMs.

Assess the Efficacy of OM-89 vs Placebo in Reducing Antibiotic Consumption Associated With the Treatment of Urinary Tract Infections in Patients With Neurogenic Bladder

Recurrent urinary tract infections (UTIs) in patients with a neurogenic bladder using clean intermittent catheterization (CIC) are a major problem. In this population, urinary tract infections are the most frequent cause of morbidity and the second leading cause of mortality (Buzzell A, Spinal Cord, 2020). It is also the leading cause of healthcare use and consumption (A. Dinh, MMI 2019). In addition, multidrug-resistant bacteria (MRB) are frequently implicated, accounting for up to 50% of cases (Samal V BMC Infect Dis 2022, A. Dinh Spnal cord 2016), due to high exposure to antibiotics and frequent and prolonged hospitalisations. The very frequent recurrence of urinary tract infections encourages exposure to antibiotics, so prevention is of vital importance. Prevention based on treatments other than antibiotics (non-antibiotic prophylaxis) is of the greatest interest, not only to prevent UTIs, but also to reduce exposure to antibiotics and the ecological pressure they exert. However, few strategies are available, and very few have been well evaluated in high-risk populations. Bacterial lysates such as Escherichia Coli extract (OM-89), an immunoactive prophylaxis, are an original and innovative strategy that has been developed for the prevention of recurrent UTIs, and could constitute a therapeutic option in particularly at-risk populations. In vivo studies have shown that OM-89 : * increases IgA levels in intestinal secretions and in the urine of mice (Bosh AV Immunopharmacol Immunotoxicol 1988; Baier W Arzneim Forsch Drug Res 1997), * stimulates the production of serum IgG and IgA recognising a number of bacteria isolated from patients with urinary tract infections and enterohaemorrhagic E. coli infections (Huber M, Int J immunopharmacol 2000), * stimulates the killing capacity of rabbit polymorphonuclear leukocytes against E. coli and S. aureus (Nauck M, Int J Exp Clin Chemother 1991), * protects against acute infection with E. coli or P. aeruginosa, * and inhibits inflammation associated with lipopolysaccharide-induced cystitis in mice (Lee SJ, World J Urol 2006). Clinically, certain studies in patients with recurrent UTIs have shown a significant reduction in the number of urinary tract infections with OM-89 compared to placebo or an antibiotic (Bauer Eur Urol 2005; Naber KG Int J Antimicrob Agents 2009; Wade DT, Clin Rehabil 2020). However, these promising results suffer from methodological limitations and need to be confirmed by a high-quality trial carried out on a sample appropriate to the research question and in a homogeneous patient population. Patients with spinal cord injuries are a population at high risk of recurrent UTIs, and prevention is a major issue, given the incidence of MRBs in this population. It is therefore important in this high-risk population not only to rigorously evaluate the efficacy of OM-89 in reducing antibiotic consumption for UTIs, but also to assess its impact on bacterial resistance and on the microbiota (urinary and digestive). These patients could therefore see significant benefits: less frequent urinary tract infections and reduced antibiotic use. In addition, this population could serve as a model for other populations with or without neurological impairment suffering from recurrent UTIs

Evaluation of Pupillometry as a Predictor of Pain Intensity Upon Withdrawal of Sedation in the Postoperative Period Following Cardiac Surgery: A Prospective Cohort Study

Postoperative pain is a significant issue following surgery, and pain that is either inadequately treated or, conversely, overtreated can increase morbidity. For example, severe chest pain following cardiac or pulmonary surgery impairs the patient's respiratory rehabilitation, which can lead to fluid retention and, consequently, pneumonia. Conversely, overtreatment through excessive use of opioids can cause drowsiness and respiratory depression. Currently, planning postoperative pain management for intubated, ventilated, and sedated patients relies on indirect signs of pain assessed using scales, and on the clinician's subjective judgment. It is only after sedation is discontinued that the actual level of pain can be assessed, once the patient becomes communicative, which then allows analgesic treatment to be adjusted to the pain. This approach inevitably results in a period of discomfort and pain for the patient. In addition to semi-quantitative and subjective scales, a number of analgesia monitoring tools have been developed. Among these, the use of pupillometry and the Pupillary Pain Index (PPI) during surgeries (gynecological, pediatric, cardiac) has been associated with a reduction in intraoperative opioid doses and a decrease in postoperative pain. In our department, pupillometry is routinely used to assess analgesia in intubated, ventilated, and sedated patients undergoing painful procedures. This method is integrated into standard care in the operating room in accordance with the PUCCAR study algorithm, as well as in the intensive care unit according to a specific departmental protocol, in addition to standard assessment scores. We hypothesize that performing pupillometry with a PPI score is predictive of pain intensity at extubation. If our hypothesis is confirmed, this would allow us to tailor analgesic management for each patient prior to discontinuing sedation.

Effectiveness of tDCS on Reducing Craving in Patients Practicing Chemsex: a Single-center, Double-blind, Randomized Controlled Pilot Trial

The aim of this research is to evaluate the efficacy of a new treatment for chemsex or "chemical sex", the use of psychoactive substances to modify sexual experience and performance. This treatment, called Transcranial direct current stimulation (tDCS) aims to modulate the cortical activity of brain areas involved in the desire to use psychoactive substances, or drugs, and the desire for uncontrolled sexual intercourse. This treatment should therefore lead to a reduction in the craving for consumption of psychoactive substances and/or the practice of uncontrolled sexual activity. The stakes of this new treatment are high, because chemsex exposes people to health risks for themselves and others. These risks include the risk of infection (skin infections, HIV infection, hepatitis viruses), psychological harms (anxiety attacks, depression, suicide risk), risk of addiction (addiction to the psychoactive product used, sex addiction), and toxicological harm (overdose, dangerous combination of psychoactive substances) or trauma (blows, trauma to the genitals or anorectal trauma). To date, there is no proven therapeutic treatment for people wishing to reduce or stop chemsex. 40 participants will be randomized into 2 groups: * 20 patients will receive active stimulation * 20 patients will receive sham stimulation The total duration of the study for each patient will be 13 weeks: 1 week of stimulation and 12 weeks of follow-up.

Evaluation of the Impact on Mental and Physical Health of Caring for Women Who Are Victims of Sexual and Gender-based Violence, Using a Coordinated Multidisciplinary Approach in Women's Centres or Traditional Health Centres.

Gender-based or sexual violence, or violence against women (VAW), is a global public health problem affecting around 30% of women over the age of 15, with significant consequences for physical and mental health, including depression and post-traumatic stress disorder (PTSD). In 2019, the French National Authority for Health (HAS) published recommendations in two parts, one for identifying women who are victims of domestic violence, and the other for dealing with a woman who has been exposed to such violence. But violence against women is not limited to the marital sphere. VAW can simply be detected in a consultation using a translated version of the Abuse Assessment Screen (AAS) questionnaire. Women who are victims of VAW have specific needs linked to the often repeated nature of the violence they experience, and the complex trauma that can ensue. They also tend to combine other risk factors for poor mental health, such as economic insecurity and social isolation. In France, dealing with the specific medical, psychosocial and legal needs of victims-survivors of VAW has come up against a number of obstacles, including a lack of dedicated care facilities, a lack of trained professionals and a lack of coordination between the various parties. Health professionals rarely receive the training they need to deal with VAW-related issues with confidence and professionalism, and often lack the resources to refer female victims to appropriate care. "La Maison des Femmes" (MdF) was set up in 2016 in Saint-Denis, located in a department where a quarter of the women who consult a family planning centre (FPC) has suffered from VAW. It is a hospital service specifically dedicated to the individualised, multidisciplinary care of victims-survivors of VAW, offering health, social and legal support within the same facility. The MdF comprises 4 units: a FPC, a violence management unit (involving doctors, midwives, psychologists, social workers, lawyers, police officers and support groups), a female genital mutilation management unit (surgeons and sexologists) and a 24/7 reception unit for victims of sexual violence. Several MdF-inspired care structures have been set up in France. The service provided by these facilities needs to be evaluated, particularly in terms of their ability to improve the physical and mental health, including post-traumatic stress, of women who have been victims of VAW.

Integration of New Generation Multi-omics Analyses for the Diagnosis of Genetic Neurodevelomental Disorders

Neurodevelopmental disorders (NDDs), including intellectual disability (ID), represent the most common indication for genetic testing. Affecting up to 3% of the general population, NDDs are characterized by significant clinical and genetic heterogeneity. Although short-read genome sequencing (srGS) has driven major advances through the France Genomic Medicine 2025 Plan (PFMG2025), a substantial proportion of patients still lack a molecular diagnosis. These results are partly explained by the limitations of short-read genome sequencing (srGS). Although effective in many cases, this technology performs poorly in detecting complex structural rearrangements, anomalies within repetitive or GC-rich regions, epigenetic variations, and certain intronic variants. Furthermore, srGS does not allow for the direct assessment of the functional impact of genetic variations on splicing or gene expression. Following a negative srGS result, periodic reanalysis of sequencing data via the PFMG2025 laboratories (AURAGEN and SeqOIA) is the only diagnostic option currently available in routine practice. However, these reanalyses are constrained by financial and staffing limitations as well as strict eligibility criteria, making it difficult for many patients-particularly those with stable neurodevelopmental disorders (NDDs)-to obtain a diagnosis. Moreover, they often consist merely of a data review without bioinformatic updates, and the turnaround times-frequently exceeding one year-contribute to the diagnostic odyssey. Utilizing updated pipelines tailored to the specific characteristics of NDDs for the re-examination of srGS data could serve as an initial source of new diagnoses. Complementary technologies-such as messenger RNA sequencing (mRNA-seq), optical genome mapping (OGM), and long-read genome sequencing (lrGS)-are available and offer solutions to overcome the limitations of short-read genome sequencing (srGS). In particular, they enable the identification of complex structural variants and the assessment of the functional impact of point variants. Despite their potential, their routine use remains limited due to cost and technical complexity. Our study proposes a combined strategy to address the limitations of current approaches and improve the diagnosis of neurodevelopmental disorders (NDDs) that remain unresolved after short-read genome sequencing (srGS). It begins with a re-analysis of sequencing data using customized bioinformatics pipelines tailored to the patients' specific clinical profiles. In cases of inconclusive results, innovative multi-omics analyses (mRNA-seq, OGM, and long-read genome sequencing/lrGS) will be employed to investigate complex genetic variants. As multi-omics approaches are not currently integrated into the PFMG2025 framework, the project's findings will be crucial in demonstrating their added value for NDD diagnosis and could pave the way for their inclusion in a future PFMG. By anticipating these developments, NextOmix will help define the diagnostic strategies of the future, aligned with technological advancements and patient needs.

Unipolar Versus Bipolar Interlocking in Humeral Shaft Fractures in Adults

Shaft fractures account for 20% of humeral fractures and 3% of all adult fractures in France, with an estimated incidence of 13 to 20/100,000 people. Men aged 21 to 30 years and women aged 60 to 80 years are particularly affected. Intramedullary nailing is among the standard treatments for humeral shaft fractures (when surgery is required). Once inserted, the nail is locked in order to limit stress on the fractured bone, as well as possible secondary rotational displacements or malunion. Bipolar interlocking (BI) is typically performed on both sides (proximal and distal) of the fracture site. This procedure is performed under radiological control, exposing the patient and care team to radiation (during the entire procedure). The objective of the treatment is to obtain consolidation of the fracture within 12 months, and to limit the occurrence of irreversible complications such as malunion or nonunion (2-10% at 12 months post-surgery). The "unipolar interlocking" (UI) technique has recently been introduced. In this technique, locking is performed only on the proximal side of the fracture site. By avoiding the distal approach, potential complications such as radial nerve damage, with the risk of irreversible paralysis (3.8-14.2% in studies of the BI technique in this indication) or the risk of infection on the distal side can be avoided. It also reduces operative time, and consequently the radiation received by patients and caregivers. However, the UI may be poorly positioned, resulting in malunion that requires revision surgery. Despite the absence of recommendations due to the lack of existing data, several teams use the UI in routine care. In this context, a descriptive cohort of 121 patients operated on at the Dijon University Hospital5 showed similar rates of consolidation between the 2 techniques (93.8% for UI versus 95.2% for BI, p=0.64), functional scores, and complications, as well as a significant 29% decrease in operating time in the UI group (mean + SD: 63.1±21.3 min versus 88.0±30.1 min for VB, p\<0.01). These encouraging results, although limited by the retrospective and observational nature of the data, justify a prospective randomized trial comparing these two techniques.

Evaluation of the Impact of Psychological Profile on Diabetic Foot Wound Healing.

Foot wounds in patients with diabetes are one of the most frequent complications associated with diabetes. Despite the progress made in its management in recent years, the risk of amputation remains high in cases of diabetic foot wounds. Several studies have highlighted the value of analyzing the psychological profile A or B, defined by self-questionnaire using Bortner's method. The A personality profile is characterized by hyperactivity, combativeness and exaggerated ambition, while the B profile is characterized by less sensitivity to stress and reduced combativeness. Type A personality profile is associated with reduced cardiovascular mortality in type 1 diabetes. Type B personality profiles have also been shown to be associated with inflammation in both type 1 and type 2 diabetes. Our group showed that patients with diabetes and a foot wound were more likely to have a type B psychological profile than patients with diabetes and no foot wound. However, to our knowledge, it has never been determined whether the psychosomatic profile type A or B assessed by the Bortner self-questionnaire influenced wound healing and the risk of amputation. The aim of this study is to determine whether type A or B psychosomatic profile influences wound healing in diabetic feet. This study will be carried out in the endocrinology, diabetology and nutrition department of the Dijon Bourgogne University Hospital. 308 patients will be included in the study.

Evaluation of the Effectiveness of Ultrasound-Guided Stellate Ganglion Block in Cardiac Surgery Anesthesia on Postoperative Recovery

Heart surgery is a complex and delicate procedure that affects more than one million people worldwide each year. Patients who undergo this surgery are generally elderly and have multiple comorbidities, which places them in high-risk categories (ASA III or IV). This frailty, combined with a loss of physiological reserve, makes these patients particularly vulnerable to postoperative complications, which can range from cardiovascular disorders to neurological, respiratory, renal, gastrointestinal, infectious, and hematological complications. In this context, the quality of postoperative recovery is crucial because it reflects the patient's postoperative health status. The quality of recovery encompasses several dimensions, such as pain, return to independence, sleep quality, and mental state. Optimal anesthesia-which goes beyond simply minimizing pain-requires proactive management of all these dimensions. Current research in cardiac surgery focuses on optimizing anesthesia strategies, particularly the choice between opioid and non-opioid anesthesia, as well as the complementary use of regional analgesia. However, studies providing clear recommendations on these topics are still limited. Among the techniques explored, the ultrasound-guided stellate ganglion block (SGB) stands out due to its numerous positive clinical effects. This block, which involves the ultrasound-guided injection of a local anesthetic into the stellate ganglion, produces a temporary sympathetic block that reduces the activity of the autonomic nervous system during surgery. Several studies suggest that SGB could significantly improve the quality of postoperative recovery, particularly in terms of pain reduction, sleep quality, and a lower incidence of cardiac arrhythmias. A meta-analysis has shown that SGB promotes the recovery of gastrointestinal function following various surgical procedures. In major thoracic surgery, it has been observed that SGB reduces the incidence of perioperative atrial and ventricular fibrillation. Although these results are promising, data from randomized trials in cardiac surgery are still limited. A pilot study demonstrated the feasibility and safety of SGB in this type of surgery, with a reduced incidence of atrial fibrillation. However, further studies are essential to confirm these results and assess the impact of SGB on the quality of recovery following anesthesia in cardiac surgery. The hypothesis of this study is that performing a stellate ganglion block during general anesthesia improves the quality of recovery in all its aspects (pain, well-being, sleep, etc.). This hypothesis warrants in-depth exploration to optimize postoperative care and improve long-term outcomes for patients undergoing complex cardiac surgery.

A Study of Taste- and Olfactory-Evoked Potentials in Patients With Visual Impairment: Taste, Smell, and Vision

Visual impairment, whether central or peripheral, may influence the plasticity of other sensory modalities, such as taste and smell. Taste-evoked potentials (TEPs) and smell-evoked potentials (SEPs)-methods for analyzing brain activity in response to taste and smell stimuli-allow for the objective assessment of these interactions. This approach has already demonstrated its value in the study of cognitive disorders. This study aims to demonstrate an enhancement of taste and smell capabilities that could compensate for specific visual impairments, particularly in situations involving food choices.

A Study of Lipid Metabolism and Mitochondrial Function in Myeloid Cells and Total Aortic Tissue in Patients With Ascending Thoracic Aortic Aneurysm (ATA) and Bicuspid (BA) or Tricuspid (TA) Aortic Valves.

Ascending aortic aneurysms (AAAs) are serious conditions that can lead to aortic dissections or ruptures, carrying a high risk of mortality. Their pathophysiology is based on complex mechanisms involving inflammatory and metabolic processes, as well as alterations in mitochondrial function. The presence of a bicuspid aortic valve (BAV) or tricuspid aortic valve (TAV) significantly influences the progression and severity of aneurysms. Bicuspid aortic valve (BAV) patients often develop aortic aneurysms earlier, as early as age 40-50, whereas tricuspid aortic valve (TAV) patients generally present with a degenerative condition that appears later (after age 50). The objective of this study is to compare the inflammatory, metabolic, and transcriptomic signatures of myeloid cells and total aortic tissue between BAV and TAV patients. These analyses will help identify specific molecular mechanisms, potential biomarkers, and therapeutic targets. To ensure pathophysiological homogeneity, patients with aneurysms of genetic origin (Marfan syndrome, Loeys-Dietz syndrome, Ehlers-Danlos syndrome, etc.) will be excluded.
