ReviewPrecision management of acute kidney injury in the intensive care unit: current state of the art.
Acute kidney injury (AKI) is a prototypical example of a common syndrome in critical illness defined by consensus. The consensus definition for AKI, traditionally defined using only serum creatinine and urine output, was needed to standardize the description for epidemiology and to harmonize eligibility for clinical trials. However, AKI is not a simple disease, but rather a complex and multi-factorial syndrome characterized by a wide spectrum of pathobiology. ⋯ Specific biomarkers (e.g., serum renin; olfactomedin 4 (OLFM4); interleukin (IL)-9) may further enable identification of pathobiological mechanisms to serve as treatment targets. However, even non-specific biomarkers of kidney injury (e.g., neutrophil gelatinase-associated lipocalin, NGAL; [tissue inhibitor of metalloproteinases 2, TIMP2]·[insulin like growth factor binding protein 7, IGFBP7]; kidney injury molecule 1, KIM-1) can direct greater precision management for specific sub-phenotypes of AKI. This review will summarize these evolving concepts and recent innovations in precision medicine approaches to the syndrome of AKI in critical illness, along with providing examples of how they can be leveraged to guide patient care.

Characterising biological mechanisms underlying ethnicity-associated outcomes in COVID-19 through biomarker trajectories: a multicentre registry analysis.
Differences in routinely collected biomarkers between ethnic groups could reflect dysregulated host responses to disease and to treatments, and be associated with excess morbidity and mortality in COVID-19. ⋯ Clinical biochemical monitoring of COVID-19 and progression and treatment response in SARS-CoV-2 infection should be interpreted in the context of ethnic background.

Lack of Useful Predictors of Dignity-Related Distress Among the Critically Ill as Assessed With the Patient Dignity Inventory.
Many intensive care unit patients are awake (ie, alert and engaging in conversation), actively experiencing many facets of their critical care. The Patient Dignity Inventory can be used to elicit sources of distress in these patients. We examined the administrative question as to which awake intensive care unit patients should be evaluated and potentially treated (eg, through palliative care consultation) for distress. Should the decision to screen for distress be based on patient demographics or treatment conditions? ⋯ Identification of subsets of patients with little potential benefit to screening for dignity-related distress would have a reduced workload of palliative care team members (eg, nurses or social workers). Our results show that this is impractical. Given that approximately one-third of critical care patients who are alert and without delirium demonstrate severe dignity-related distress, all such patients with prolonged intensive care unit length of stay should probably be evaluated for distress.

Extracorporeal membrane oxygenation (ECMO) is an invasive intervention that is both resource- and labor-intensive. It can also be emotionally challenging for all involved. Palliative care (PC) clinicians can support adult patients, families, surrogate decision makers, and the interdisciplinary team (IDT) throughout ECMO, starting at the time of ECMO initiation through discontinuation and to bereavement in the event of a patient's death. ⋯ Not only are PC clinicians' skills needed to manage symptoms and psychosocial needs but also during end-of-life care, which can often be rapid and requires team consensus to ensure a smooth clinical process with continuous family support. While using their expert communication skills to conduct frequent family meetings, ideally starting within one week of ECMO initiation and weekly thereafter, PC clinicians offer a consistent presence and "big picture" perspective for patients and families, while other members of the IDT may rotate regularly. PC clinicians will also be called on to assist members of the IDT to debrief about the understandable moral and emotional distress they may experience while providing care for patients receiving ECMO and their families.

After an intensive care unit (ICU) admission, nearly 20% of survivors of chronic critical illness require admission to a long-term acute care hospital (LTACH) for continued subspecialty care. The effect of the burden of medical comorbidities on discharge disposition after LTACH admission remains unclear. ⋯ Severity-of-illness scores on admission to an LTACH can be used to predict patients' likelihood of being discharged home.
