ReviewDysbiosis in the intensive care unit: Microbiome science coming to the bedside.
Complex microbial communities within the human body, constituting the microbiome, have a broad impact on human health and disease. A growing body of research now examines the role of the microbiome in patients with critical illness, such as sepsis and acute respiratory failure. In this article, we provide an introduction to microbiome concepts and terminology and we systematically review the current evidence base of the critical-illness microbiome, including 51 studies in animal models and pediatric and adult critically ill patients. ⋯ The evolving molecular, culture-independent techniques offer the ability to study microbial communities in unprecedented depth and detail, and in the short-term, may enable us to diagnose and treat infections in critical care more precisely and effectively. Longer term, these tools may also give us insights in the underlying pathophysiology of critical illness and reveal previously unsuspected targets for innovative, microbiome-targeted therapeutics. We finally propose a roadmap for future studies in the field for transforming critical care from its current isolated focus on the host to a more personalized paradigm addressing both human and microbial contributions to critical illness.

ReviewCircadian disruption of ICU patients: A review of pathways, expression, and interventions.
Intensive care unit patients typically exhibit pathologic wakefulness, poor quality of daytime sleep, nocturnal sleep fragmentation, and sleep patterns that feature the absence of slow wave sleep and rapid eye movement. This article offers a review of the existing literature examining circadian desynchronization in critically ill patients, highlighting contributing factors identified by scholars, and circadian abnormalities observed in these patients. It discusses potential implications for clinical practice and suggests avenues of future research. Elucidating the role of circadian rhythms in the management of critical illness can guide future chronotherapeutic approaches and optimize patient outcomes.

Multicenter StudyMagnitude of temperature elevation is associated with neurologic and survival outcomes in resuscitated cardiac arrest patients with postrewarming pyrexia.
Avoidance of pyrexia is recommended in resuscitation guidelines, including after treatment with targeted temperature management (TTM). Which aspects of postresuscitation pyrexia are harmful and modifiable have not been conclusively determined. ⋯ In postarrest TTM-treated patients, pyrexia was associated with increased survival. Patients experiencing postrewarming pyrexia had worse outcomes at higher temperatures. Longer pyrexia duration was associated with worse outcomes at higher temperatures.

ReviewParacetamol in fever in critically ill patients-an update.
Fever, which is arbitrary defined as an increase in body temperature above 38.3°C, can affect up to 90% of patients admitted in intensive care unit. Induction of fever is mediated by the release of pyrogenic cytokines (tumor necrosis factor α, interleukin 1, interleukin 6, and interferons). Fever is associated with increased length of stay in intensive care unit and with a worse outcome in some subgroups of patients (mainly neurocritically ill patients). ⋯ Paracetamol is a synthetic, nonopioid, centrally acting analgesic, and antipyretic drug. Its antipyretic effect occurs because it inhibits cyclooxygenase-3 and the prostaglandin synthesis, within the central nervous system, resetting the hypothalamic heat-regulation center. In this clinical review, we will summarize the use of paracetamol as antipyretic in critically ill patients (sepsis, trauma, neurological, and medical).

Combining quick Sequential Organ Failure Assessment with plasma lactate concentration is comparable to standard Sequential Organ Failure Assessment score in predicting mortality of patients with and without suspected infection.
We sought to determine whether quick Sequential Organ Failure Assessment (qSOFA) score can be used to predict mortality of patients without suspected infection. ⋯ The qSOFA score had a modest ability to predict mortality of both septic and nonseptic patients; combining qSOFA with plasma lactate had a predictive ability comparable to the standard SOFA score.
