Clinical trials

Approximately 40% of patients develop muscle dysfunction during their stay in intensive care, particularly in the context of sepsis. This dysfunction represents an acquired muscle injury that is secondary to the primary illness that led to ICU admission. It affects both the limb muscles and the respiratory muscles of the thoracic cage. Clinically, this manifests as bilateral and symmetrical muscle weakness in the limbs, and contributes significantly to difficulties in weaning patients off mechanical ventilation. The loss of muscle mass is directly correlated with the severity of the patient's clinical condition and can reach up to 20% of initial muscle mass within just ten days. This rapid and profound atrophy primarily results from an imbalance between increased muscle protein breakdown (catabolism) and insufficient protein synthesis (anabolism). The consequences of this muscle dysfunction are significant and far-reaching, with a marked negative impact on the overall prognosis. This condition is associated with longer durations of mechanical ventilation and extended stays in the intensive care unit. Beyond the acute phase, patients often experience persistent reductions in physical performance, leading to long-term functional limitations that impair quality of life. Furthermore, ICU-acquired muscle dysfunction has been linked to increased long-term mortality, with excess deaths reported at both one year and five years following ICU discharge. This risk is especially pronounced when the muscle dysfunction is severe and continues beyond the hospitalization period. Several risk factors for ICU-acquired muscle dysfunction may be modifiable, opening up the possibility for preventive or therapeutic interventions. Two main factors have been identified as particularly relevant: (1) the duration of immobility and muscular inactivity, and (2) the adequacy of nutritional support, especially regarding amino acid intake, which is critical for maintaining muscle protein synthesis. In response to these factors, early and active mobilization of ICU patients has become a key component of recommended care, often in conjunction with strategies aimed at minimizing the use of sedative medications. These practices are encouraged by international guidelines, reflecting a growing consensus around the importance of maintaining some level of muscular activity even in critically ill patients. However, despite these recommendations, no definitive evidence has demonstrated a clear improvement in patient outcomes associated with early mobilization. This lack of clear benefit may stem from multiple factors, including the variability in patient severity across clinical trials and, importantly, the timing of the intervention. The anabolic signals triggered by muscle contraction are only effective if they are strong enough to counterbalance the catabolic signals driven by inflammation, infection, or muscle hypoxia-all of which fluctuate over the course of illness and recovery. Regarding nutritional interventions, the appropriate timing and quantity of calorie and protein intake necessary to support adequate anabolism and mitigate muscle loss remain controversial. Although amino acids are essential for muscle protein synthesis, current studies have not shown consistent improvements in muscle function based on different nutritional strategies in the ICU setting. Given the high prevalence of ICU-acquired muscle dysfunction in patients with sepsis, its significant impact on outcomes, and the lack of an effective, evidence-based treatment, there is a pressing need to deepen our scientific understanding of this phenomenon. Improving knowledge in this area could lead to more targeted and effective interventions, ultimately helping to preserve muscle mass and function in critically ill patients and improving both their short- and long-term prognosis.

Lateral ankle sprains account for nearly 6,500 emergency department visits per day in France. They are clinically classified into three grades, which can be assessed approximately 3-5 days after an acute sprain. However, this classification remains somewhat approximate, with only mild and severe sprains being reliably identified. When it comes to immobilization, if weight-bearing is possible, treatment options include an elastic ankle brace for mild sprains, taping, or a semi-rigid orthosis known as a "stabilizing" brace. It is worth noting that, according to Rodineau and Besch, the preferred form of immobilization is the semi-rigid orthosis. In cases of severe sprains where weight-bearing is not possible, rigid immobilization may be used. To date, few thesis-level studies have focused on trauma care and the outpatient follow-up of ankle sprains. Two studies from the early 2010s assessed general practice management of trauma using questionnaires-one in Seine-Maritime and another in Bouches-du-Rhône. The latter study found that 96.7% of surveyed physicians reported managing all types of sprains. In the Seine-Maritime study, half of the physicians systematically followed up on ankle sprains, while the other half only did so if the patient's condition worsened. It was also found that nearly 47% of physicians referred their patients directly to emergency departments. This pathway was more frequently chosen by urban practitioners or those without specific training in trauma care. Except in certain predefined cases depending on the hospital, there is currently no systematic follow-up for ankle sprains in emergency departments. Most patients are redirected toward follow-up in outpatient care. The objective of this research project is to assess the recovery of baseline quality of life in participants who consulted the emergency department of Saint-Brieuc for an ankle sprain, three months after the injury. The evaluation will take into account the type of follow-up care (physician, physiotherapist) as well as the severity of the sprain.

End-of-life care is often accompanied by anxiety-not only for patients in palliative care, but also for their loved ones and the healthcare professionals supporting them. This anxiety may stem from a fear of death, loss of functional abilities, or a worsening of symptoms as the illness progresses. It contributes to emotional, psychological, and physical suffering, ultimately diminishing patients' quality of life. Most data on palliative care focus on cancer patients, among whom anxiety prevalence varies greatly, but may affect more than 70% of individuals. Currently, anxiety in palliative care patients is managed through non-pharmacological approaches (such as environmental modifications and relaxation techniques) and/or pharmacological treatments (including antidepressants, neuroleptics, and anxiolytics). The investigators recently developed the serious game SPAMLO with the aim to present and raise awareness about palliative care. The educational scenario was built around three settings: the hospital, the home, and the nursing home (EHPAD). The participant will follow Vito, a virtual character, whose sister is receiving palliative care. Vito will explore the different types of support available, starting at the hospital. He will learn about what a collegial discussion is, the Clayes-Léonetti law, advance directives, the trusted person, as well as the specificities of pediatrics. Through home hospitalization, Vito will discover palliative care outside the hospital setting, including home adaptations with appropriate equipment and the various available support services. Finally, Vito will visit the nursing home, where topics such as oral care, respecting the patient's choices, and the importance of preserving them will be addressed. Thanks to its playful approach and the knowledge gained, this game could help reduce anxiety in palliative care patients through non-pharmacological means. This research project has beeen co-designed with a JALMALV volunteer (Accompany life until death - french association).
