With an ever-increasing number of COVID-19 survivors, providers are tasked with addressing the longer lasting symptoms of COVID-19, or postacute sequelae of SARS-CoV-2 infection (PASC). For critically ill patients, existing knowledge about postintensive care syndrome (PICS) represents a useful structure for understanding PASC. Post-ICU clinics leverage a multidisciplinary team to evaluate and treat the physical, cognitive, and psychological sequelae central to both PICS and PASC in critically ill patients. While management through both pharmacologic and nonpharmacologic modalities can be used, further research into both the optimal treatment and prevention of PASC represents a key public health imperative.

ReviewAcute Neurologic Complications of COVID-19 and Postacute Sequelae of COVID-19.
Neurologic complications can be seen in mild to severe COVID-19 with a higher risk in patients with severe COVID-19. These can occur as a direct consequence of viral infection or consequences of treatments. ⋯ Outcomes depend on severity of underlying COVID-19, patient age, comorbidities, and severity of the complication. Postacute sequelae of COVID-19 range from fatigue, headache, dysosmia, brain fog, anxiety, depression to an overlap with postintensive care syndrome.

Extracorporeal membrane oxygenation (ECMO) is an intervention for severe acute respiratory distress syndrome (ARDS). Although COVID-19-related ARDS has some distinct features, its overall clinical presentation resembles ARDS from other etiologies. ⋯ Current evidence suggests that ECMO in COVID-19-related ARDS has similar efficacy and safety profile as for non-COVID-19 ARDS. The high number of severe COVID-19 cases and demand for therapies, such as ECMO, poses a unique opportunity to increase the understanding on how to optimize this intervention.

ReviewCOVID-19 Acute Respiratory Distress Syndrome: One Pathogen, Multiple Phenotypes.
Acute respiratory distress syndrome (ARDS) is a heterogeneous syndrome arising from multiple causes with a range of clinical severity. In recent years, the potential for prognostic and predictive enrichment of clinical trials has been increased with identification of more biologically homogeneous subgroups or phenotypes within ARDS. COVID-19 ARDS also exhibits significant clinical heterogeneity despite a single causative agent. In this review the authors summarize the existing literature on COVID-19 ARDS phenotypes, including physiologic, clinical, and biological subgroups as well as the implications for improving both prognostication and precision therapy.

Initial reporting suggested that kidney involvement following COVID-19 infection was uncommon but this is now known not to be the case. Acute kidney injury (AKI) may arise through several mechanisms and complicate up to a quarter of patients hospitalized with COVID-19 infection being associated with an increased risk for both morbidity and death. ⋯ The mainstay of treatment remains the prevention of worsening kidney damage and in some cases they need for renal replacement therapies (RRT). Although the use of other blood purification techniques has been proposed as potential treatments, results to-date have not been definitive.
