Delay From Hypotension Onset to Appropriate Antifungal Therapy Initiation Is the Critical Determinant of Outcome in Candida Septic Shock.
In 850 patients with Candida septic shock, survival was 86 percent with appropriate antifungals within two hours but fell about five percent per hour of delay thereafter.
Abhishek A et al. · Critical Care Medicine · 2026
From the briefingIn Critical Care Medicine, Abhishek and colleagues analysed 850 adults with culture-positive Candida septic shock across 32 hospitals in Canada, the United States, and Saudi Arabia, spanning nearly three decades [1]. The odds of death rose by roughly four to five percent for every hour that appropriate antifungal therapy was delayed after persistent hypotension began. When an antifungal matched to the isolated organism was given within 2 hours, hospital survival was 86 percent, and it then fell by about five percentage points per hour out to ten or twelve hours. Time to appropriate therapy was the single strongest predictor of outcome, even after accounting for illness severity, and the effect held across infection sites, species, and drug classes. The sobering part is the care gap: the median time to appropriate therapy was about 32 hours, and fewer than one in five patients received it within 6 hours. This is retrospective work over a long era, so residual confounding is possible, but it extends to fungal shock the time-dependence long described for bacterial sepsis, and it sharpens the question of who should receive empirical antifungal cover before cultures return.
If you only have time for one paper this week, make it the Candida septic shock cohort from Abhishek and colleagues in Critical Care Medicine [1]. It quantifies, hour by hour, how much survival appears to be lost while antifungal therapy is delayed, and exposes a median delay of more than a day, reopening the debate over empirical antifungal strategies in high-risk shock.

Heterogeneous cardiovascular responses to acute mean arterial pressure augmentation in septic shock: the role of ventriculo-arterial coupling and venous return.
Raising MAP from 65 to 85 in septic shock produced divergent responses, with about one in six patients losing cardiac output through worsened ventriculo-arterial coupling in a small physiological study.
Valenzuela ED et al. · Critical Care · 2026
From the briefingMoving from timing to physiology, Valenzuela and colleagues, writing in Critical Care, raised mean arterial pressure from about 65 to 85 in 32 ventilated patients with septic shock and measured the response with echocardiography [2]. Despite similar pressure gains, the responses diverged: about a third of patients increased cardiac output, roughly half held steady, and about one in six lost forward flow. Those who lost flow showed a rise in arterial load without matching contractile reserve, so ventriculo-arterial coupling worsened, along with falling ejection fraction and changes in venous return indices. It is a small physiological study, but it supports the view that a higher pressure target is not uniformly beneficial for flow.

Brachial-to-Radial Pressure Gradient in Critically Ill Patients Treated With Vasoactive Agents: A Prospective Observational Study.
Nearly one in five ICU patients on vasoactive drugs had a brachial-to-radial pressure gradient above 11 mmHg, independently linked to higher vasopressor dose and accompanied by higher mortality.
Putowski Z et al. · Critical Care Medicine · 2026
From the briefingFinally, Putowski and colleagues in Critical Care Medicine compared cuff brachial pressure with invasive radial pressure in 303 patients on vasoactive drugs across thirteen Polish ICUs [3]. Nearly one in five patients had a gradient above 11 millimetres of mercury, and only vasoactive dose was independently linked to it. Patients with a significant gradient were sicker, with higher lactate and slower capillary refill, and ICU mortality was close to half compared with about thirty percent. The observational design cannot say which reading is closer to central pressure, but it raises the possibility that the radial line underestimates pressure precisely in the patients receiving the highest vasopressor doses.

Comparative Analysis of Tracheal Intubation-Associated Cardiac Arrest in 2015-2023: A Report From the National Emergency Airway Registry for Children Multicenter Registry.
Among nearly 28,000 paediatric ICU intubations, cardiac arrest occurred in 1.2 percent, rising with shock and each extra attempt, while video laryngoscopy and ketamine were associated with lower odds.
Padiyath A et al. · Critical Care Medicine · 2026
From the briefingIn Critical Care Medicine, Padiyath and colleagues report on nearly 28,000 intubations from the National Emergency Airway Registry for Children across seventy international paediatric and cardiac ICUs [4]. Cardiac arrest within twenty minutes of intubation occurred in about one in a hundred procedures. Shock before intubation was associated with nearly five times the odds of arrest, and oxygenation failure with more than double the odds, while each additional attempt raised the odds by about seventy percent. Ketamine, propofol, neuromuscular blockade, and video laryngoscopy were each associated with lower odds of arrest. Mediation analysis suggested that only about thirteen percent of the video laryngoscopy benefit came through fewer attempts, so something beyond first-pass success appears to be at work. As registry data these associations are not causal, but they reinforce first-attempt success and pre-intubation haemodynamic optimisation as plausible targets.

Association of Acute Respiratory Distress Syndrome Radiographic Findings Identified by Machine Learning and Outcomes of Patients Receiving Invasive Mechanical Ventilation.
A deep learning chest radiograph ARDS score predicted 28-day mortality and longer time to extubation independently of oxygenation and illness severity in a single-centre cohort of 6,591 ventilated patients.
Zhong Y et al. · Critical Care Medicine · 2026
From the briefingAlso in Critical Care Medicine, Zhong and colleagues applied a deep learning model that scores ARDS-type opacities on chest radiographs to more than 6,500 patients at the start of ventilation in a single centre [5]. Patients with a positive score had 28-day mortality of about 35 percent versus about 14 percent in patients with a negative score, and even scores below the ARDS threshold stratified risk. The score discriminated mortality modestly but somewhat better than the oxygenation ratio, and it remained associated with death and longer time to extubation after adjusting for hypoxaemia or illness severity. External validation is still needed, but the authors argue that an imaging-based severity measure could inform trial enrichment or a future ARDS definition.

Toward targeted assessment of inspiratory muscle weakness before extubation: a pooled individual patient data analysis from multiple observational cohorts in critically ill ventilated patients.
Maximal inspiratory pressure of 30 cmH2O or less predicted extubation failure only after more than five days of ventilation, while expiratory pressure, cough flow and MRC scores showed no association.
Medrinal C et al. · Critical Care · 2026
From the briefingAt the other end of ventilation, Medrinal and colleagues in Critical Care pooled individual data from observational cohorts of 494 ventilated adults to test bedside neuromuscular measures before extubation [6]. Across all patients, a maximal inspiratory pressure of 30 centimetres of water or less was only borderline associated with extubation failure. But in patients ventilated for more than five days, about a third of those with low inspiratory pressure failed extubation versus about one in seven of those above the threshold, and the association survived adjustment. Expiratory pressure, cough flow, and limb strength scores showed no adjusted association. This supports targeting inspiratory pressure testing at patients after prolonged ventilation rather than screening everyone, though missing measurements across cohorts limit precision.

Music Therapy During Weaning From Invasive Mechanical Ventilation in the ICU: A Randomized Controlled Trial.
In a 100-patient randomised trial, daily music therapy did not shorten weaning from mechanical ventilation, though secondary outcomes suggested less agitation, less propofol use and fewer tracheostomies.
Pereiro S et al. · Critical Care Medicine · 2026
From the briefingAnd in a randomised trial of 100 ventilated adults, again in Critical Care Medicine, Pereiro and colleagues tested daily individualised music therapy during weaning [7]. The primary outcome was negative: weaning duration did not differ between groups. Secondary results favoured music therapy, with less agitation, a smaller share of patients needing propofol, and a lower tracheostomy rate, while stress scores, ventilation time, and ICU stay were lower but not significantly so. With a negative primary endpoint and many secondary comparisons, these signals are hypothesis-generating rather than proof of benefit.

Furosemide Stress Test in Adults and Children With Acute Kidney Injury: A Systematic Review and Meta-Analysis.
The furosemide stress test predicted AKI progression and kidney replacement therapy liberation on low-certainty evidence, while test-guided early dialysis showed no detectable mortality effect in two small trials.
Tran PNT et al. · Critical Care Medicine · 2026
From the briefingIn Critical Care Medicine, Tran and colleagues meta-analysed twenty studies of the furosemide stress test in adults and children with acute kidney injury [8]. The test predicted progression to stage 3 injury and successful liberation from kidney replacement therapy with good discrimination, but the certainty of evidence was low, and it was rated very low for predicting dialysis initiation and death. In two small randomised trials, using the test to guide early dialysis made no detectable difference to mortality. The authors position it as an inexpensive risk-stratification tool, particularly where novel biomarkers are unavailable, rather than a trigger for treatment.

Principles of drug dosing for obese patients in the intensive care unit.
A narrative review finds limited ICU-specific evidence for dosing in severe obesity and proposes an individualised framework centred on choosing the correct dosing weight and pharmacodynamic targets.
Barletta JF et al. · Intensive Care Medicine · 2026
From the briefingIn Intensive Care Medicine, Barletta and Erstad review drug dosing in critically ill patients with severe obesity [9]. They note that the evidence base is thin, with few patients at the extremes of weight, few clinical outcomes, and little ICU-specific data, and that altered volume of distribution and clearance can undermine target attainment. Their framework centres on individualised dosing, choosing the correct weight for each calculation, and they suggest pharmacist input may help.

European Society of Intensive Care Medicine consensus statement on human-centred partnership in the intensive care unit.
An ESICM panel with patient and family input endorsed 43 consensus statements supporting flexible visiting, structured communication, staff and patient psychological support, and environmental measures against delirium.
Latour JM et al. · Intensive Care Medicine · 2026
From the briefingAlso in Intensive Care Medicine, Latour and colleagues present the European Society of Intensive Care Medicine consensus on human-centred partnership in the ICU [10]. A 46-member panel, with patient and family representatives and two Delphi rounds of more than a hundred stakeholders, endorsed 43 statements supporting flexible family visiting, structured interdisciplinary communication, empathy training, psychological support for both patients and staff, culturally responsive care, and environmental measures for sleep and delirium. It is consensus built on rapid reviews rather than trial evidence, but it pairs naturally with the music therapy trial as an attempt to formalise humane care.

Welcome to This Week in Critical Care. This week we're covering 10 notable papers spanning shock and haemodynamic monitoring, the airway and liberation from mechanical ventilation, and the bedside tools and frameworks that shape everyday ICU care. Let's dive in.
We start with shock, where three papers look at timing, physiology, and how we measure blood pressure. In Critical Care Medicine, Abhishek and colleagues analysed 850 adults with culture-positive Candida septic shock across 32 hospitals in Canada, the United States, and Saudi Arabia, spanning nearly three decades [1]. The odds of death rose by roughly four to five percent for every hour that appropriate antifungal therapy was delayed after persistent hypotension began. When an antifungal matched to the isolated organism was given within 2 hours, hospital survival was 86 percent, and it then fell by about five percentage points per hour out to ten or twelve hours. Time to appropriate therapy was the single strongest predictor of outcome, even after accounting for illness severity, and the effect held across infection sites, species, and drug classes. The sobering part is the care gap: the median time to appropriate therapy was about 32 hours, and fewer than one in five patients received it within 6 hours. This is retrospective work over a long era, so residual confounding is possible, but it extends to fungal shock the time-dependence long described for bacterial sepsis, and it sharpens the question of who should receive empirical antifungal cover before cultures return. Moving from timing to physiology, Valenzuela and colleagues, writing in Critical Care, raised mean arterial pressure from about 65 to 85 in 32 ventilated patients with septic shock and measured the response with echocardiography [2]. Despite similar pressure gains, the responses diverged: about a third of patients increased cardiac output, roughly half held steady, and about one in six lost forward flow. Those who lost flow showed a rise in arterial load without matching contractile reserve, so ventriculo-arterial coupling worsened, along with falling ejection fraction and changes in venous return indices. It is a small physiological study, but it supports the view that a higher pressure target is not uniformly beneficial for flow. Finally, Putowski and colleagues in Critical Care Medicine compared cuff brachial pressure with invasive radial pressure in 303 patients on vasoactive drugs across thirteen Polish ICUs [3]. Nearly one in five patients had a gradient above 11 millimetres of mercury, and only vasoactive dose was independently linked to it. Patients with a significant gradient were sicker, with higher lactate and slower capillary refill, and ICU mortality was close to half compared with about thirty percent. The observational design cannot say which reading is closer to central pressure, but it raises the possibility that the radial line underestimates pressure precisely in the patients receiving the highest vasopressor doses.
Our second theme follows the airway from intubation through to extubation. In Critical Care Medicine, Padiyath and colleagues report on nearly 28,000 intubations from the National Emergency Airway Registry for Children across seventy international paediatric and cardiac ICUs [4]. Cardiac arrest within twenty minutes of intubation occurred in about one in a hundred procedures. Shock before intubation was associated with nearly five times the odds of arrest, and oxygenation failure with more than double the odds, while each additional attempt raised the odds by about seventy percent. Ketamine, propofol, neuromuscular blockade, and video laryngoscopy were each associated with lower odds of arrest. Mediation analysis suggested that only about thirteen percent of the video laryngoscopy benefit came through fewer attempts, so something beyond first-pass success appears to be at work. As registry data these associations are not causal, but they reinforce first-attempt success and pre-intubation haemodynamic optimisation as plausible targets. Also in Critical Care Medicine, Zhong and colleagues applied a deep learning model that scores ARDS-type opacities on chest radiographs to more than 6,500 patients at the start of ventilation in a single centre [5]. Patients with a positive score had 28-day mortality of about 35 percent versus about 14 percent in patients with a negative score, and even scores below the ARDS threshold stratified risk. The score discriminated mortality modestly but somewhat better than the oxygenation ratio, and it remained associated with death and longer time to extubation after adjusting for hypoxaemia or illness severity. External validation is still needed, but the authors argue that an imaging-based severity measure could inform trial enrichment or a future ARDS definition. At the other end of ventilation, Medrinal and colleagues in Critical Care pooled individual data from observational cohorts of 494 ventilated adults to test bedside neuromuscular measures before extubation [6]. Across all patients, a maximal inspiratory pressure of 30 centimetres of water or less was only borderline associated with extubation failure. But in patients ventilated for more than five days, about a third of those with low inspiratory pressure failed extubation versus about one in seven of those above the threshold, and the association survived adjustment. Expiratory pressure, cough flow, and limb strength scores showed no adjusted association. This supports targeting inspiratory pressure testing at patients after prolonged ventilation rather than screening everyone, though missing measurements across cohorts limit precision. And in a randomised trial of 100 ventilated adults, again in Critical Care Medicine, Pereiro and colleagues tested daily individualised music therapy during weaning [7]. The primary outcome was negative: weaning duration did not differ between groups. Secondary results favoured music therapy, with less agitation, a smaller share of patients needing propofol, and a lower tracheostomy rate, while stress scores, ventilation time, and ICU stay were lower but not significantly so. With a negative primary endpoint and many secondary comparisons, these signals are hypothesis-generating rather than proof of benefit.
Our final theme gathers bedside tools and practice frameworks. In Critical Care Medicine, Tran and colleagues meta-analysed twenty studies of the furosemide stress test in adults and children with acute kidney injury [8]. The test predicted progression to stage 3 injury and successful liberation from kidney replacement therapy with good discrimination, but the certainty of evidence was low, and it was rated very low for predicting dialysis initiation and death. In two small randomised trials, using the test to guide early dialysis made no detectable difference to mortality. The authors position it as an inexpensive risk-stratification tool, particularly where novel biomarkers are unavailable, rather than a trigger for treatment. In Intensive Care Medicine, Barletta and Erstad review drug dosing in critically ill patients with severe obesity [9]. They note that the evidence base is thin, with few patients at the extremes of weight, few clinical outcomes, and little ICU-specific data, and that altered volume of distribution and clearance can undermine target attainment. Their framework centres on individualised dosing, choosing the correct weight for each calculation, and they suggest pharmacist input may help. Also in Intensive Care Medicine, Latour and colleagues present the European Society of Intensive Care Medicine consensus on human-centred partnership in the ICU [10]. A 46-member panel, with patient and family representatives and two Delphi rounds of more than a hundred stakeholders, endorsed 43 statements supporting flexible family visiting, structured interdisciplinary communication, empathy training, psychological support for both patients and staff, culturally responsive care, and environmental measures for sleep and delirium. It is consensus built on rapid reviews rather than trial evidence, but it pairs naturally with the music therapy trial as an attempt to formalise humane care.
If you only have time for one paper this week, make it the Candida septic shock cohort from Abhishek and colleagues in Critical Care Medicine [1]. It quantifies, hour by hour, how much survival appears to be lost while antifungal therapy is delayed, and exposes a median delay of more than a day, reopening the debate over empirical antifungal strategies in high-risk shock.
Here is what this week's evidence adds up to in Critical Care. First, observational data now suggest that delays to appropriate antifungal therapy in Candida septic shock carry a steep, time-dependent mortality cost, though how to select patients for earlier empirical cover remains unsettled. Second, small physiological and multicentre observational studies indicate that a single pressure number can mislead, whether through divergent flow responses to higher targets or through radial lines reading lower than cuffs on high-dose vasopressors; neither yet defines a new standard. Third, in paediatric intubation, registry data link shock, repeated attempts, and the absence of video laryngoscopy or certain induction agents to peri-intubation arrest, strengthening the case for first-pass success without proving causation. Fourth, weaning tools look most informative when targeted, with low inspiratory pressure predicting failure mainly after prolonged ventilation, while music therapy did not shorten weaning in its trial. And finally, the furosemide stress test and obesity dosing frameworks offer pragmatic guidance resting on low-certainty evidence, so their outcome benefit is still unproven.
