Purpose: Cannabis is the most used recreational drug worldwide, and is increasingly used for medicinal purposes, however little is known about its impact on patients in intensive care units (ICU). Our objective was to identify key themes in the literature surrounding cannabis in the ICU and identify future research priorities.
Methods: Four databases were systematically searched for literature investigating the impact of cannabis, and evidence for its therapeutic use, in adult ICU patients.
Results: Of 2589 articles screened, 22 articles were included for analysis. Cannabis-associated admissions were primarily related to an outbreak of vaping associated lung injury, and synthetic cannabinoid toxicity. Studies on the impact of cannabis use on outcomes were mostly limited to trauma and burns populations, with an inconsistent mortality benefit, and a trend towards increased pain scores and analgesic requirements found. There is minimal research on its therapeutic uses in ICU, with two trials investigating the use of a synthetic cannabinoid in patients with severe traumatic brain injury, with ultimately no significant effect on intracranial pressure found.
Conclusions: There is a paucity of studies investigating the impact of cannabinoids or their therapeutic uses in critically ill patients, with further research in this area needed.

Fluid administration is widely used to treat hypotension in patients undergoing veno-venous extracorporeal membrane oxygenation (VV-ECMO). However, excessive fluid administration may lead to fluid overload can aggravate acute respiratory distress syndrome (ARDS) and increase patient mortality, predicting fluid responsiveness is of great significance for VV-ECMO patients. This prospective single-center study was conducted in a medical intensive care unit (ICU) and finally included 51 VV-ECMO patients with ARDS in the prone position (PP).

Electronic cigarettes (e-cigs) fundamentally differ from tobacco cigarettes in their generation of liquid-based aerosols. Investigating how e-cig aerosols behave when inhaled into the dynamic environment of the lung is important for understanding vaping-related exposure and toxicity. A ventilated artificial lung model was developed to replicate the ventilatory and environmental features of the human lung and study their impact on the characteristics of inhaled e-cig aerosols from simulated vaping scenarios.

Sacubitril/valsartan, a first-in-class angiotensin receptor neprilysin inhibitor, is widely used to treat heart failure. Despite its efficacy, sacubitril/valsartan inevitably causes adverse events such as hypotension, renal dysfunction, hyperkalemia, and angioedema. Sacubitril/valsartan-associated ototoxicity is often underreported in clinical studies and real-world settings.

While circular RNAs (circRNAs) exhibit lower abundance compared to corresponding linear RNAs, they demonstrate potent biological functions. Nevertheless, challenges arise from the low concentration and distinctive structural features of circRNAs, rendering existing methods operationally intricate and less sensitive. Here, we engineer an intelligent tetrahedral DNA framework (TDF) possessing precise spatial pattern-recognition properties with exceptional sensing speed and sensitivity for circRNAs.
