Changes in Restricting Symptoms after Critical Illness among Community-Living Older Adults.
Rationale: Survivors of critical illness have multiple symptoms, but how restricting symptoms change after critical illness and whether these changes differ among vulnerable subgroups is unknown. Objectives: To evaluate changes in restricting symptoms over the six months after critical illness among older adults and to determine whether these changes differ by sex, multimorbidity, and individual- and neighborhood-level socioeconomic disadvantage. Methods: From a prospective longitudinal study of 754 community-living adults ⩾70 years old interviewed monthly (1998-2018), we identified 233 admissions from 193 participants to the ICU. ⋯ Increases in restricting symptoms did not differ significantly by sex, multimorbidity, or individual- or neighborhood-level socioeconomic disadvantage. Conclusions: Restricting symptoms increase substantially after a critical illness before returning to baseline three months after hospital discharge. Our findings highlight the need to incorporate symptom management into post-ICU care and for further investigation into whether addressing restricting symptoms can improve quality of life and functional recovery among older ICU survivors.

Evidence from fatal COVID-19 for targeting the bradykinin metabolism - a single-center cohort study.
Background: Severe progression of COVID-19 to critical illness, with pulmonary failure, multiple organ failure, and death, is driven by systemic inflammatory responses with overproduction of inflammatory cytokines. In the past years, the potential role of bradykinin, leading to inappropriate immune responses in the pathogenesis of COVID-19, has been raised in a so-called bradykinin storm. However, clinical investigations of bradykinin, its metabolite des-Arg 9 -bradykinin, or substance P, are rare or completely lacking during intensive care of COVID-19 patients. ⋯ Conclusion: Our data demonstrates that des-Arg 9 -bradykinin is significantly elevated in COVID-19 intensive care unit patients and is associated with disease severity, clinical inflammatory parameters, and survival. These results indicate that des-Arg 9 -bradykinin, not bradykinin, is one of the pivotal peptides of concern for the lethal COVID-19 aggravation and outcome. Further investigations are necessary to evaluate whether des-Arg 9 -bradykinin exhibits potent blood biomarker properties in COVID-19 and offer new treatment approaches.

Observational StudyParental Adverse Childhood Experiences and Post-PICU Stress in Children and Parents.
Hospitalization in a PICU is a stressful experience for children and their parents, with many experiencing posttraumatic stress disorder (PTSD) after discharge. Risk factors may include preillness traumatic events, such as adverse childhood experiences (ACEs). We sought to assess the feasibility of screening ACEs in parents of children admitted to a PICU, their prevalence, and their association with post-PICU PTSD symptoms in them and their children. ⋯ ACEs were common among parents of critically ill children. Having substantial parental ACEs was associated with provisional parental PTSD after their child's PICU admission, but not with PTSD in the children. Family-centered care that seeks to mitigate post-PICU stress should be mindful of the potential relevance of parental ACEs.

Plasma Nitric Oxide Consumption Is Elevated and Associated With Adverse Outcomes in Critically Ill Patients.
Impaired nitric oxide (NO) bioavailability may contribute to microvascular dysfunction in sepsis. Excessive plasma NO consumption has been attributed to scavenging by circulating cell-free hemoglobin. This may be a mechanism for NO deficiency in sepsis and critical illness. We hypothesized that plasma NO consumption is high in critically ill patients, particularly those with sepsis, acute respiratory distress syndrome (ARDS), shock, and in hospital nonsurvivors. We further hypothesized that plasma NO consumption is correlated with plasma cell-free hemoglobin concentration. ⋯ Plasma NO consumption is elevated in critically ill patients and independently associated with sepsis, ARDS, shock, and hospital death. These data suggest that excessive intravascular NO scavenging characterizes sepsis and adverse outcomes of critical illness.

Parental Perception and Measured Functional Status Following Pediatric Critical Illness: A Secondary Analysis of the Survivor Outcomes Study.
We evaluated the concordance between parent/guardian perception of child long-term function and objectively scored long-term functional status using the Functional Status Scale (FSS) among PICU survivors. ⋯ These findings shed light on a critical disconnect between parent/guardian perspective and our current tools to measure a child's functional status following critical illness. In an era of decreased PICU mortality and increased long-term morbidity, the discordance between parent/guardian perception and available scoring tools in the assessment of long-term functional status highlights a key opportunity to improve communication and anchor expectations for long-term outcomes among PICU survivors.
