The purpose of this review is to examine the current state of the evidence, including several recent systematic reviews and meta-analyses, to determine if proportional modes of ventilation have the potential to hasten weaning from mechanical ventilation for adult critically ill patients, compared to pressure support ventilation (PSV), the current standard of care during the recovery and weaning phases of mechanical ventilation. ⋯ The current state of the evidence suggests that proportional modes may hasten weaning from mechanical ventilation, but larger, multicentre RCTS are needed to confirm these preliminary findings.

ReviewHow to prevent and how to treat dyspnea in critically ill patients undergoing invasive mechanical ventilation.
To summarize current data regarding the prevalence, risk factors, consequences, assessment and treatment of dyspnea in critically ill patients receiving invasive mechanical ventilation. ⋯ As opposed to pain, dyspnea has often been overlooked in terms of detection and management, resulting in its significant underestimation in daily practice. When it is diagnosed, dyspnea can be relieved through straightforward interventions, such as adjusting ventilator settings. Assessing dyspnea in patients undergoing invasive mechanically ventilated may be challenging, especially in noncommunicative patients (RRBS). Implementing a systematic dyspnea assessment in routine, akin to pain, could serve as a first step to reduce RRBS and prevent potential severe psychological consequences. In addition to pharmacological treatments like opioids, a promising approach is to modulate both the sensory (air on the face, trigeminal nerve stimulation) and the affective (relaxing music, hypnosis, directed empathy) components of dyspnea.

Background : Continuous kidney replacement therapy (CKRT) is a crucial intervention for hemodynamically unstable patients with acute kidney injury (AKI). Despite the recommendations to offer a CKRT dose of 20 to 25 mL/kg/h, the optimal CKRT dose remains uncertain, especially whether low-dose CKRT is associated with poor outcomes. This study investigated the association between low CKRT dosage and 90-day mortality using a marginal structural model (MSM). ⋯ Additionally, there were no significant associations between the delivered CKRT dose and 90-day mortality within the range of 5 to 40 mL/kg/h. Conclusion : This study highlights the impact of methodological approaches on the association between CKRT dose and mortality and that with personalized adjustments, there may not be a lower limit of the unsafe CKRT dose. However, lower CKRT doses were initially associated with higher mortality, and adjusting for time-dependent variables nullified this association.

Identification and quantification of physical activity in critically ill burn patients: A feasibility study.
Physical activity is essential in burn care to counteract the effects of severe burns and inactivity during hospitalization. However, detailed knowledge of performed physical activities is lacking. This study evaluated the feasibility of a dual accelerometer-based method to assess type, frequency, and duration of physical activity in critically ill burn patients during hospitalization. ⋯ The dual accelerometer-based method proved feasible for research purposes. For clinical application, further refinement of data processing is required.

Mechanisms underlying neurocognitive dysfunction following critical illness: a systematic review.
Cognitive impairment is a significant healthcare problem globally and its prevalence is projected to affect over 150 million people worldwide. Survivors of critical illness are impacted frequently by long-term neurocognitive dysfunction regardless of presenting illness, but the mechanisms are poorly understood. The goal of this review was to synthesise the existing evidence regarding potential mechanisms underlying neurocognitive dysfunction following critical illness in order to guide potential avenues for future research. ⋯ The underlying pathophysiology of neurocognitive decline after critical illness is not yet understood fully. The mechanisms implicated in other neurodegenerative conditions suggest that this may represent an accelerated version of the same processes. Large scale studies are required to further elucidate the cause of this significant problem for survivors of critical illness.
