Upper arm anthropometrics versus DXA scan in survivors of acute respiratory distress syndrome.

ABSTRACT: Survivors of acute respiratory distress syndrome (ARDS) experience severe muscle wasting. Upper arm anthropometrics can provide a quick, non-invasive estimate of muscle status, but its accuracy is unknown. This study examines the accuracy of upper arm percent muscle area (UAMA) with reference measures of lean mass from dual energy X-ray absorptiometry (DXA). Data are from 120 ARDS survivors participating in a multicenter national study. Receiver operating characteristic (ROC) curves, by patient sex, demonstrated that UAMA did no better than chance in discriminating low appendicular skeletal muscle mass identified using DXA findings (c-statistics, 6 months: 0.50-0.59, 12 months: 0.54-0.57). Modest correlations of UAMA with DXA measures (whole-body: r?=?0.46-0.49, arm-specific: r?=?0.50-0.51, p?

Project description:ObjectivesMuch of the research related to pediatric acute respiratory distress syndrome has focused on inhospital mortality and interventions affecting this outcome. Limited data exist on survivors' morbidity, hospital disposition, and 1-year survival. The aim of this study was to determine new morbidity rate, discharge disposition, and 1-year mortality for survivors of pediatric acute respiratory distress syndrome.DesignSecondary analysis of prospective cohort study.SettingQuaternary children's hospital.PatientsThree-hundred sixteen mechanically ventilated children with pediatric acute respiratory distress syndrome (Berlin and Pediatric Acute Lung Injury Consensus Conference criteria) between July 2011 and December 2014.InterventionsNone.Measurements and main resultsWe performed secondary analysis of a prospectively recruited cohort of 316 mechanically ventilated children with pediatric acute respiratory distress syndrome between July 2011, and December 2014. Preillness and hospital discharge Functional Status Scale score were determined via chart review, and factors associated with new morbidity, defined as an increase of Functional Status Scale score of 3 or more, were analyzed. Demographic variables, pediatric acute respiratory distress syndrome characteristics, and ventilator management were tested for association with development of new morbidity, discharge disposition, and 1-year mortality. Inhospital mortality of pediatric acute respiratory distress syndrome was 13.3% (42/316). Of 274 survivors to hospital discharge, new morbidity was seen in 63 patients (23%). Discharge to rehabilitation rate was 24.5% (67/274) and associated with development of new morbidity. One- and 3-year mortality of survivors was 5.5% (15 deaths) and 8% (22 deaths) and was associated with baseline Functional Status Scale, immunocompromised status, Pediatric Risk of Mortality III, and organ failures at pediatric acute respiratory distress syndrome onset, but not with pediatric acute respiratory distress syndrome severity.ConclusionsNew morbidity was common after pediatric acute respiratory distress syndrome and appears to be intermediate phenotype between survival without morbidity and death, making it a useful metric in future interventional and outcome studies in pediatric acute respiratory distress syndrome.

Project description:ObjectivesTo describe 3-6-month neurologic outcomes of survivors of COVID-19-associated acute respiratory distress syndrome, invasively ventilated in the ICU.DesignA bicentric prospective study during the two first waves of the pandemic (March to May and September to December, 2020).SettingTwo academic hospital ICUs, Paris, France.PatientsAdult COVID-19-associated acute respiratory distress syndrome survivors, invasively ventilated in the ICU, were eligible for a neurologic consultation between 3 and 6 months post ICU discharge.InterventionsFollow-up by face-to-face neurologic consultation.Measures and main resultsThe primary endpoint was favorable functional outcome defined by a modified Rankin scale score less than 2, indicating survival with no significant disability. Secondary endpoints included mild cognitive impairment (Montreal Cognitive Assessment score < 26), ICU-acquired weakness (Medical Research Council score < 48), anxiety and depression (Hospital Anxiety and Depression score > 7), and posttraumatic stress disorder (posttraumatic stress disorder checklist for Diagnostic and Statistical Manual of Mental Disorders 5 score > 30). Of 54 eligible survivors, four non-French-speaking patients were excluded, eight patients were lost-to-follow-up, and one died during follow-up. Forty-one patients were included. Time between ICU discharge and neurologic consultation was 3.8 months (3.6-5.9 mo). A favorable functional outcome was observed in 16 patients (39%) and mild cognitive impairment in 17 of 33 patients tested (52%). ICU-acquired weakness, depression or anxiety, and posttraumatic stress disorder were reported in six of 37 cases (16%), eight of 31 cases (26%), and two of 27 cases (7%), respectively. Twenty-nine patients (74%) required rehabilitation (motor, cognitive, or psychologic). ICU and hospital lengths of stay, tracheostomy, and corticosteroids were negatively associated with favorable outcome. By contrast, use of alpha-2 agonists during ICU stay was associated with favorable outcome.ConclusionsCOVID-19-associated acute respiratory distress syndrome requiring intubation led to slight-to-severe functional disability in about 60% of survivors 4 months after ICU discharge. Cognitive impairment, muscle weakness, and psychologic symptoms were frequent. A large multicenter study is warranted to allow identification of modifiable factors for improving long-term outcome.
