ICU-acquired weakness (ICUAW) develops in roughly half of mechanically ventilated patients and causes durable muscle dysfunction, reduced exercise capacity and curtailed autonomy that persist for years, with impact on quality of life and healthcare utilization. The diagnostic framework remains limited: the Medical Research Council sum score is informative at ICU discharge but loses sensitivity during convalescence, and capturing the full deficit requires multidimensional assessment of muscle function, physical function and quality of life, in line with the PRACTICE core outcome set and the conceptual continuum from acute ICUAW to post-ICU sarcopenia. Two pillars structure current therapy - nutritional support and physical rehabilitation. Nutritional support: avoidance of severe hyperglycaemia is established, but large RCTs consistently show that escalating acute-phase calorie or protein delivery does not improve, and may worsen, outcomes, particularly in vulnerable subgroups such as those with acute kidney injury. This paradox is explained by the concept of feeding responsiveness: anabolic resistance blunts muscle protein synthesis in a way that cannot be overcome by dose escalation; as inflammation and metabolism recover, a catabolic-to-anabolic transition restores nutrient utilization, and dynamic biomarkers (urea trajectory, phosphate kinetics, insulin resistance index) may identify the catabolic-to-anabolic transition at the bedside. These insights translate into a four-phase individualized strategy spanning permissive underfeeding with conditional escalation, standard targets, protocol-guided individualized support during early (in-hospital) convalescence, and enriched nutrition with structured dietitian-led follow-up after discharge. Physical rehabilitation: early mobilization improves short-term outcomes - muscle strength at ICU discharge, duration of mechanical ventilation and length of stay - but recent trials, notably TEAM, show that augmented-dose mobilization does not translate into long-term functional benefit and may harm identifiable subgroups, mirroring the nutritional paradox. The concept of exercise responsiveness - captured by clinical signatures of non-response (diabetes, low achievable ICU Mobility Scale, illness severity) and molecular determinants (persistent inflammation, mitochondrial and proteostatic dysfunction) - supports a four-phase physiology-informed prescription, from safety-first early mobilization to home-based adapted physical activity sustaining a continuous training stimulus. Beyond these two pillars, emerging metabolic support offers complementary, biology-targeted interventions still under preclinical and translational development. These include alternative oxidative substrates, autophagy and mitochondrial modulators, and anabolic agents - forcing anabolism acutely may be harmful, as growth hormone","PeriodicalId":7966,"journal":{"name":"Annals of Intensive Care","volume":"16 ","pages":"100137"},"PeriodicalIF":6.9,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13571473/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148963035","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This multicenter survey aimed to describe diagnostic and therapeutic management practices of ICU physicians in France for high-risk invasive candidiasis cases, using randomized clinical case simulations distributed to French ICU physicians via email and academic congresses.</p><p><strong>Results: </strong>A total of 75 physicians completed 283 cases. Overall, clinical suspicion justified diagnostic investigation in 72.1% of cases. Key factors associated with the decision to test for invasive candidiasis included post-abdominal surgery (OR = 3.92; p = 0.002), central venous catheter (OR = 2.28; p = 0.04), parenteral nutrition (OR = 2; p = 0.027), prolonged antibiotic exposure (OR = 1.90; p = 0.041), and physician experience >10 years (OR = 2.79; p = 0.014). Echinocandins were the preferred first-line treatment (88.2%; n = 120/136). Their use was guided by clinical guidelines (78.3%), pharmacokinetic/pharmacodynamic profile (38.3%), SOFA score (29.2%), patient status (25.8%), and immunosuppression (20%). De-escalation to azoles upon documented mycological susceptibility occurred in 87.5% of cases initially treated with an echinocandin and 60.0% of cases initiated on amphotericin B, primarily after 5 days of treatment (51.2%; n = 64).</p><p><strong>Conclusions: </strong>Patient severity, immunosuppression, and catheter presence were the main factors guiding antifungal treatment decisions Management of confirmed invasive candidiasis was largely consensual among respondents, whereas empirical treatment decisions were heterogeneous. While conclusions are primarily reflective of practice patterns within specialized university hospital centers, the INSPIRE survey highlights the need for enhanced training, broader access to rapid diagnostics, and improved decision-support systems to better harmonize clinical practices.</p>","PeriodicalId":7966,"journal":{"name":"Annals of Intensive Care","volume":"16 ","pages":"100131"},"PeriodicalIF":6.9,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13476721/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148761342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
