The level of inflammation alters drug pharmacokinetics (PK) in critically ill patients. This might compromise treatment efficacy. Understanding the specific effects of inflammation, measured by biomarkers, on drug absorption, distribution, metabolism, and excretion is might help in optimizing dosing strategies. ⋯ Inflammatory biomarkers can offer valuable information regarding altered PK in critically ill patients. Our findings emphasize the need to consider inflammation-driven PK variability when individualizing drug therapy in this setting, at the same time research is limited to certain drugs and needs further research, also including pharmacodynamics.

Extubation is a crucial step in the weaning process of critically ill mechanically ventilated patients. Some patients may develop postextubation respiratory failure that may lead to the need for re-intubation, which is associated with increased morbidity and mortality. This review comprehensively explores postextubation respiratory support strategies, focusing on the efficacy of high-flow nasal cannula (HFNC) oxygen therapy and noninvasive ventilation (NIV) in reducing re-intubation rates among various patient populations. ⋯ NIV, alternatively, appears to provide substantial advantages in reducing the rates of re-intubation and respiratory failure, especially in patients with obesity and patients with hypercapnia. Therefore, the indiscriminate application of these support strategies without consideration of individual patient characteristics may not improve outcomes, highlighting the need for careful patient selection and tailored therapeutic strategies based on specific risk factors and clinical conditions. By aligning postextubation respiratory support strategies with patient-specific needs, we may improve the success rates of extubation, enhance overall recovery, and reduce the burden of reintubations in the intensive care setting.

Review Meta AnalysisCorticosteroids in critically ill patients with community-acquired pneumonia: A systematic review and Bayesian meta-analysis.
This systematic review and meta-analysis aimed to evaluate the effectiveness and safety of adjunct systemic corticosteroid therapy in patients admitted to the intensive care unit (ICU) with bacterial community-acquired pneumonia (CAP). ⋯ Corticosteroids significantly reduced mechanical ventilation requirements, and hydrocor-tisone significantly reduced hospital mortality. Further work is required to determine whether other corticosteroids reduce mortality among ICU patients with CAP.

Adaptive pressure control-continuous mandatory ventilation (APC-CMV) is a frequently utilized ventilator mode in ICU settings. This analysis compared APC-CMV and traditional volume control-continuous mandatory ventilation (VC-CMV) mode, describing factors associated with initiation, maintenance, and changes in settings of each mode. ⋯ APC-CMV was highly utilized in the medical ICU. Subjects on APC-CMV had more ventilator setting changes/d than those on VC-CMV. APC-CMV offered no advantage of reduced setting adjustments or less sedation compared to VC-CMV.

Review Meta Analysis
Efficacy of Continuous Lateral Rotation Therapy in Mechanically Ventilated Critically Ill Adults on Clinical Outcomes.
This Population, Intervention, Comparison, and Outcomes-guided systematic review assesses continuous lateral rotation therapy versus conventional position changes in mechanically ventilated critically ill adults, evaluating mortality, ICU length of stay (LOS), and hospital LOS as primary outcomes and respiratory function, mechanical ventilation duration, pulmonary complications, and adverse events as secondary outcomes. ⋯ Continuous lateral rotation therapy showed no significant difference in primary outcomes (mortality, ICU and hospital LOS) but revealed significant differences in secondary outcomes (consistently reduced nosocomial pneumonia, with a minor effect on mechanical ventilation duration), supported by moderate certainty. Very low certainty for other outcomes highlights the need for current studies in diverse clinical settings and protocols to assess continuous lateral rotation therapy effectiveness.
