BackgroundTheMUC5Bpromoter variant (rs35705950) and telomere length are linked to pulmonary fibrosis and CT-based qualitative assessments of interstitial abnormalities, but their associations with longitudinal quantitative changes of the lung interstitium among community-dwelling adults are unknown.MethodsWe used data from participants in the Multi-Ethnic Study of Atherosclerosis with high-attenuation areas (HAAs, Examinations 1–6 (2000–2018)) andMUC5Bgenotype (n=4552) and telomere length (n=4488) assessments. HAA was defined as the per cent of imaged lung with attenuation of −600 to −250 Hounsfield units. We used linear mixed-effects models to examine associations ofMUC5Brisk allele (T) and telomere length with longitudinal changes in HAAs. Joint models were used to examine associations of longitudinal changes in HAAs with death and interstitial lung disease (ILD).ResultsTheMUC5Brisk allele (T) was associated with an absolute change in HAAs of 2.60% (95% CI 0.36% to 4.86%) per 10 years overall. This association was stronger among those with a telomere length below an age-adjusted percentile of 5% (p value for interaction=0.008). A 1% increase in HAAs per year was associated with 7% increase in mortality risk (rate ratio (RR)=1.07, 95% CI 1.02 to 1.12) for overall death and 34% increase in ILD (RR=1.34, 95% CI 1.20 to 1.50). Longer baseline telomere length was cross-sectionally associated with less HAAs from baseline scans, but not with longitudinal changes in HAAs.ConclusionsLongitudinal increases in HAAs were associated with theMUC5Brisk allele and a higher risk of death and ILD.

Rationale: Early mobilization of ECMO-supported patients is increasingly common, but it remains unknown whether there are factors predictive of achieving higher intensity mobilization among those a...

Recent Bayesian reanalyses of prominent trials in critical illness have generated controversy by contradicting the initial conclusions based on conventional frequentist analyses. Many clinicians might be sceptical that Bayesian analysis, a philosophical and statistical approach that combines prior beliefs with data to generate probabilities, provides more useful information about clinical trials than the frequentist approach. In this Personal View, we introduce clinicians to the rationale, process, and interpretation of Bayesian analysis through a systematic review and reanalysis of interventional trials in critical illness. In the majority of cases, Bayesian and frequentist analyses agreed. In the remainder, Bayesian analysis identified interventions where benefit was probable despite the absence of statistical significance, where interpretation depended substantially on choice of prior distribution, and where benefit was improbable despite statistical significance. Bayesian analysis in critical care medicine can help to distinguish harm from uncertainty and establish the probability of clinically important benefit for clinicians, policy makers, and patients.

High-attenuation areas (HAA) are a computed tomography-based quantitative measure of subclinical interstitial lung disease (ILD). We aimed to validate HAA in lung regions that are less subject to artefacts, such as extravascular lung water or dependent atelectasis. We examined the associations of HAA within six lung regions (basilar, non-basilar, peel, core, basilar peel, basilar core) with serum biomarkers of lung remodelling, forced vital capacity (FVC), visually-assessed interstitial lung abnormalities (ILA), and all-cause and ILD-specific mortality. We performed cross-sectional and longitudinal analyses of participants in the Multi-Ethnic Study of Atherosclerosis, a prospective cohort of 6814 adults aged 45–84 years without known cardiovascular disease who underwent cardiac computed tomography. Median regional HAA ranged from 3.8% in the peel to 4.8% in the basilar core. Doubling of regional HAA was associated with greater serum matrix metalloproteinase-7 (range 3.8% to 10.3%; p≤0.01), higher odds of ILA (OR 1.42 to 2.20; p≤0.03), and a higher risk of all-cause mortality (hazard ratio 1.20 to 1.47; p≤0.001). Doubling of regional HAA was associated with greater serum interleukin-6 (4.9% to 10.3%; p≤0.005) and higher risk of ILD-specific mortality (hazard ratio 3.30 to 3.98; p, Even when found in small regions of the lungs, high-attenuation areas, a CT-based quantitative measure of subclinical ILD, are associated with biomarkers of lung remodelling, risk of interstitial lung abnormalities and all-cause mortality http://bit.ly/36psfin

Lung-protective ventilation strategies are the current standard of care for patients with acute respiratory distress syndrome in an effort to provide adequate ventilatory requirements while minimizing ventilator-induced lung injury. Some patients may benefit from ultra-lung-protective ventilation, a strategy that achieves lower airway pressures and Vt than the current standard. Specific physiological parameters beyond severity of hypoxemia, such as driving pressure and respiratory system elastance, may be predictive of those most likely to benefit. Because application of ultra-lung-protective ventilation is often limited by respiratory acidosis, extracorporeal membrane oxygenation or extracorporeal carbon dioxide removal, which remove carbon dioxide from blood, is an attractive option. These strategies are associated with hematological complications, especially when applied at low blood-flow rates with devices designed for higher blood flows, and a recent large randomized controlled trial failed to show a benefit from an extracorporeal carbon dioxide removal-facilitated ultra-lung-protective ventilation strategy. Only in patients with very severe forms of acute respiratory distress syndrome has the use of an ultra-lung-protective ventilation strategy-accomplished with extracorporeal membrane oxygenation-been suggested to have a favorable risk-to-benefit profile. In this critical care perspective, we address key areas of controversy related to ultra-lung-protective ventilation, including the trade-offs between minimizing ventilator-induced lung injury and the risks from strategies to achieve this added protection. In addition, we suggest which patients might benefit most from an ultra-lung-protective strategy and propose areas of future research.

Rationale: Interstitial lung abnormalities (ILAs) are associated with the highest genetic risk locus for idiopathic pulmonary fibrosis (IPF); however, the extent to which there are unique associations among individuals with ILAs or additional overlap with IPF is not known. Objectives: To perform a genome-wide association study (GWAS) of ILAs. Methods: ILAs and a subpleural-predominant subtype were assessed on chest computed tomography (CT) scans in the AGES (Age Gene/Environment Susceptibility), COPDGene (Genetic Epidemiology of Chronic Obstructive Pulmonary Disease [COPD]), Framingham Heart, ECLIPSE (Evaluation of COPD Longitudinally to Identify Predictive Surrogate End-points), MESA (Multi-Ethnic Study of Atherosclerosis), and SPIROMICS (Subpopulations and Intermediate Outcome Measures in COPD Study) studies. We performed a GWAS of ILAs in each cohort and combined the results using a meta-analysis. We assessed for overlapping associations in independent GWASs of IPF. Measurements and Main Results: Genome-wide genotyping data were available for 1,699 individuals with ILAs and 10,274 control subjects. The MUC5B (mucin 5B) promoter variant rs35705950 was significantly associated with both ILAs (P = 2.6 × 10(−27)) and subpleural ILAs (P = 1.6 × 10(−29)). We discovered novel genome-wide associations near IPO11 (rs6886640, P = 3.8 × 10(−8)) and FCF1P3 (rs73199442, P = 4.8 × 10(−8)) with ILAs, and near HTRE1 (rs7744971, P = 4.2 × 10(−8)) with subpleural-predominant ILAs. These novel associations were not associated with IPF. Among 12 previously reported IPF GWAS loci, five (DPP9, DSP, FAM13A, IVD, and MUC5B) were significantly associated (P

Most low-income and middle-income countries (LMICs) have little or no data integrated into a national surveillance system to identify characteristics or outcomes of COVID-19 hospital admissions and the impact of the COVID-19 pandemic on their national health systems. We aimed to analyse characteristics of patients admitted to hospital with COVID-19 in Brazil, and to examine the impact of COVID-19 on health-care resources and in-hospital mortality.We did a retrospective analysis of all patients aged 20 years or older with quantitative RT-PCR (RT-qPCR)-confirmed COVID-19 who were admitted to hospital and registered in SIVEP-Gripe, a nationwide surveillance database in Brazil, between Feb 16 and Aug 15, 2020 (epidemiological weeks 8-33). We also examined the progression of the COVID-19 pandemic across three 4-week periods within this timeframe (epidemiological weeks 8-12, 19-22, and 27-30). The primary outcome was in-hospital mortality. We compared the regional burden of hospital admissions stratified by age, intensive care unit (ICU) admission, and respiratory support. We analysed data from the whole country and its five regions: North, Northeast, Central-West, Southeast, and South.Between Feb 16 and Aug 15, 2020, 254 288 patients with RT-qPCR-confirmed COVID-19 were admitted to hospital and registered in SIVEP-Gripe. The mean age of patients was 60 (SD 17) years, 119 657 (47%) of 254 288 were aged younger than 60 years, 143 521 (56%) of 254 243 were male, and 14 979 (16%) of 90 829 had no comorbidities. Case numbers increased across the three 4-week periods studied: by epidemiological weeks 19-22, cases were concentrated in the North, Northeast, and Southeast; by weeks 27-30, cases had spread to the Central-West and South regions. 232 036 (91%) of 254 288 patients had a defined hospital outcome when the data were exported; in-hospital mortality was 38% (87 515 of 232 036 patients) overall, 59% (47 002 of 79 687) among patients admitted to the ICU, and 80% (36 046 of 45 205) among those who were mechanically ventilated. The overall burden of ICU admissions per ICU beds was more pronounced in the North, Southeast, and Northeast, than in the Central-West and South. In the Northeast, 1545 (16%) of 9960 patients received invasive mechanical ventilation outside the ICU compared with 431 (8%) of 5388 in the South. In-hospital mortality among patients younger than 60 years was 31% (4204 of 13 468) in the Northeast versus 15% (1694 of 11 196) in the South.We observed a widespread distribution of COVID-19 across all regions in Brazil, resulting in a high overall disease burden. In-hospital mortality was high, even in patients younger than 60 years, and worsened by existing regional disparities within the health system. The COVID-19 pandemic highlights the need to improve access to high-quality care for critically ill patients admitted to hospital with COVID-19, particularly in LMICs.National Council for Scientific and Technological Development (CNPq), Coordinating Agency for Advanced Training of Graduate Personnel (CAPES), Carlos Chagas Filho Foundation for Research Support of the State of Rio de Janeiro (FAPERJ), and Instituto de Salud Carlos III.

Objectives: In mechanically ventilated patients, deep sedation is often assumed to induce “respirolysis,” that is, lyse spontaneous respiratory effort, whereas light sedation is often assumed to preserve spontaneous effort. This study was conducted to determine validity of these common assumptions, evaluating the association of respiratory drive with sedation depth and ventilator-free days in acute respiratory failure. Design: Prospective cohort study. Setting: Patients were enrolled during 2 month-long periods in 2016–2017 from five ICUs representing medical, surgical, and cardiac specialties at a U.S. academic hospital. Patients: Eligible patients were critically ill adults receiving invasive ventilation initiated no more than 36 hours before enrollment. Patients with neuromuscular disease compromising respiratory function or expiratory flow limitation were excluded. Interventions: Respiratory drive was measured via P0.1, the change in airway pressure during a 0.1-second airway occlusion at initiation of patient inspiratory effort, every 12 ± 3 hours for 3 days. Sedation depth was evaluated via the Richmond Agitation-Sedation Scale. Analyses evaluated the association of P0.1 with Richmond Agitation-Sedation Scale (primary outcome) and ventilator-free days. Measurements and Main Results: Fifty-six patients undergoing 197 bedside evaluations across five ICUs were included. P0.1 ranged between 0 and 13.3 cm H2O (median [interquartile range], 0.1 cm H2O [0.0–1.3 cm H2O]). P0.1 was not significantly correlated with the Richmond Agitation-Sedation Scale (RSpearman, 0.02; 95% CI, –0.12 to 0.16; p = 0.80). Considering P0.1 terciles (range less than 0.2, 0.2–1.0, and greater than 1.0 cm H2O), patients in the middle tercile had significantly more ventilator-free days than the lowest tercile (incidence rate ratio, 0.78; 95% CI, 0.65–0.93; p < 0.01) or highest tercile (incidence rate ratio, 0.58; 95% CI, 0.48–0.70; p < 0.01). Conclusions: Sedation depth is not a reliable marker of respiratory drive during critical illness. Respiratory drive can be low, moderate, or high across the range of routinely targeted sedation depth.

Background Application of extracorporeal life support (ECLS) for advanced pulmonary hypertension (PH) is evolving and may be deployed as a bridge to transplantation (BTT) or in one of several non-BTT uses, such as bridge to recovery (BTR) to the chronic PH clinical state in the setting of an acute PH trigger, bridge through non-transplant surgery (BTNTS), or bridge post-transplantation (BPT). Methods We conducted a retrospective analysis of all adult patients with World Symposium on Pulmonary Hypertension Group 1, 3, 4, or 5 PH who received ECLS at Columbia University Medical Center/New York Presbyterian Hospital between January 1, 2010 and August 18, 2018. We describe patient characteristics, outcomes, and our approach to medical and surgical management of these patients. Results There were 98 patients with significant PH in the cohort (54 female; median age, 48 years [interquartile range, 32–58]). Of these, 44 (45%) patients with PH received ECLS as non-BTT with intent to recover back to their baseline functional state, optimize therapy, or support through a definitive surgery, including 19 BTR, 17 BTNTS, and 8 BPT, and 54 (55%) patients received ECLS as BTT. In the overall cohort, 67 (68.4%) patients received venoarterial ECLS and 31 (31.6%) received venovenous (VV) ECLS. Out of 83 patients, 52 (63%) were liberated from invasive mechanical ventilation, and 85.2% of BTT patients with PH ambulated while on ECLS. Management of PH medications was individualized, often requiring titration with use of inhaled pulmonary vasodilators increased after cannulation in non-BTT. Overall 30-day survival was 73.5%, survival to ECLS decannulation was 66.3%, and survival to hospital discharge was 54.1%. All 8 BPT patients (100%) survived to hospital discharge, 64.7% of BTNTS patients survived to hospital discharge, and 32 (59.3%) BTT patients survived to lung transplantation. Early-era use of VV-ECLS for BTT had worse survival to discharge than those initially configured with venoarterial ECLS, impacting the overall survival and leading to limited use of VV-ECLS in the current era for BPT, BTNTS, and select BTR cases. Conclusions ECLS instituted by a specialized, multidisciplinary team has a role in the management of advanced PH as BTT or as non-BTT (including BTR, BTNTS, and BPT). Careful selection of ECLS cannulation configurations, patient-specific optimization of PH medical therapies, and avoidance of endotracheal intubation may be effective strategies in managing these complex patients.

Purpose To characterize monitoring of pain, agitation, and delirium; investigate opioid and sedative choices; and describe prevention and treatment of delirium in adults receiving venovenous extracorporeal membrane oxygenation (vv-ECMO) for respiratory failure. Materials and methods International, cross-sectional survey distributed January 2018 to members of the Society of Critical Care Medicine. Results Respondents were predominately physicians (58%) from North America (89%). Fentanyl (77%) and hydromorphone (48%) were the most common intravenous opioids used to manage pain. A deep level of sedation was targeted in the first 24-h after initiation of vv-ECMO 64% of the time. When deep sedation was targeted, propofol (70%) and benzodiazepines (41%) were the most common sedatives. The most common sedatives for light sedation were dexmedetomidine (45%) and propofol (39%). Delirium prevention included avoidance of benzodiazepines (73%), whereas the most common treatment strategy was scheduled atypical antipsychotics (83%). Centers that extubated patients during vv-ECMO used dexmedetomidine as the second preferred sedative as compared to benzodiazepines at non-extubating centers (p = 0.04). Conclusions Most respondents use validated scales and protocols to assess and manage pain, agitation/sedation, and delirium. The majority of respondents reported targeting a deep level of sedation with propofol being used for both deep and light levels of sedation.

Background Lung fibrosis is attributed to derangements in extracellular matrix remodeling, a process driven by collagen turnover. We examined the association of two collagen biomarkers, carboxy-terminal telopeptide of collagen type I (ICTP) and amino-terminal propeptide of type III procollagen (PIIINP), with subclinical interstitial lung disease (ILD) in adults. Methods We performed a cross-sectional analysis of 3244 participants age 45–84 years in the Multi-Ethnic Study of Atherosclerosis. Serum ICTP and PIIINP levels were measured at baseline by radioimmunoassay. Subclinical ILD was defined as high attenuation areas (HAA) in the lung fields on baseline cardiac CT scans. Interstitial lung abnormalities (ILA) were measured in 1082 full-lung CT scans at 9.5 years median follow-up. We used generalized linear models to examine the associations of collagen biomarkers with HAA and ILA. Results Median (IQR) for ICTP was 3.2 μg/L (2.6–3.9 μg/L) and for PIIINP was 5.3 μg/L (4.5–6.2 μg/L). In fully adjusted models, each SD increment in ICTP was associated with a 1.3% increment in HAA (95% CI 0.2–2.4%, p = 0.02) and each SD increment in PIIINP was associated with a 0.96% increment in HAA (95% CI 0.06–1.9%, p = 0.04). There was no association between ICTP or PIIINP and ILA. There was no evidence of effect modification by gender, race, smoking status or eGFR. Conclusions Higher levels of collagen biomarkers are associated with greater HAA independent of gender, race and smoking status. This suggests that extracellular matrix remodeling may accompany subclinical ILD prior to the onset of clinically evident disease.

Understanding ICU workflow and how it is impacted by ICU strain is necessary for implementing effective improvements. This study aimed to quantify how ICU physicians spend time and to examine the impact of ICU strain on workflow.Prospective, observational time-motion study.Five ICUs in two hospitals at an academic medical center.Thirty attending and resident physicians.None.In 137 hours of field observations, the most time-84 hours (62% of total observation time)-was spent on professional communication. Reviewing patient data and documentation occupied a combined 52 hours (38%), whereas direct patient care and education occupied 24 hours (17%) and 13 hours (9%), respectively. The most frequently used tool was the computer, used in tasks that occupied 51 hours (37%). Severity of illness of the ICU on day of observation was the only strain factor that significantly impacted work patterns. In a linear regression model, increase in average ICU Sequential Organ Failure Assessment was associated with more time spent on direct patient care (β = 4.3; 95% CI, 0.9-7.7) and education (β = 3.2; 95% CI, 0.7-5.8), and less time spent on documentation (β = -7.4; 95% CI, -11.6 to -3.2) and on tasks using the computer (β = -7.8; 95% CI, -14.1 to -1.6). These results were more pronounced with a combined strain score that took into account unit census and Sequential Organ Failure Assessment score. After accounting for ICU type (medical vs surgical) and staffing structure (resident staffed vs physician assistant staffed), results changed minimally.Clinicians spend the bulk of their time in the ICU on professional communication and tasks involving computers. With the strain of high severity of illness and a full unit, clinicians reallocate time from documentation to patient care and education. Further efforts are needed to examine system-related aspects of care to understand the impact of workflow and strain on patient care.

Objective: To assess the feasibility of utilizing real time three-dimensional echocardiography (RT3DE) for assessment of diastolic function during stress. Methods: Rest and stress volumes were acquired in 24 patients and parameters of diastolic function—peak ventricular filling rate (PFR) and time to peak filling rate (TPFR)—were calculated. Results: Calculation of diastolic parameters was feasible in all patients. Resting PFR correlated with end-diastolic (EDV) and stroke volumes and inversely with TPFR (r = 0.53, 0.66, –0.5). With stress, PFR increased by 93% and TPFR decreased by 23% (P < 0.001). Stress PFR correlated with stress heart rate, EDV and stroke volume (r = 0.52, 0.50, 0.62) while TPFR correlated inversely with heart rate (r =–0.71). The change in PFR with stress correlated with the change in stroke volume (r = 0.42), while the change in TPFR correlated with the change in end-systolic volume (ESV) (r = 0.43) and inversely with the change in diastolic blood pressure (r =–0.41). Rest and stress PFR and TPFR are independent of age, gender and blood pressure and the change in PFR is independent of stress heart rate or blood pressure. E/E′ correlated with stress TPFR (r = 0.72) and change in TPFR (r = 0.67) and inversely with change in PFR (r =–0.67). Conclusions: RT3DE can assess diastolic function during stress by detecting changes in PFR and TPFR, independent of gender, age, and blood pressure. The changes in these parameters with stress are influenced by baseline filling pressures. Larger studies are required to validate the clinical significance of these observations.

Early diastolic mitral annular velocities (E') are routinely generated by tissue Doppler imaging (TDI), an angle-dependent technique. Velocity vector imaging (VVI) lacks this limitation. Normal VVI E' values and their correlation with TDI E' are unknown.E' by VVI and TDI were compared in 100 patients.VVI velocities are lower and correlate moderately with TDI velocities for medial E' (r = 0.405) and mildly for lateral E' (r = 0.278) and are image quality dependent. In patients with diastolic or systolic dysfunction, no correlation was found. E'0.06 m/s by VVI for the medial and lateral annulus can detect abnormal diastolic function with sensitivity of 90% and 77%, respectively, and with specificity of 56% and 52%, respectively.E' by VVI is lower than by TDI with a poor agreement between the measurements, which are therefore not interchangeable. Although VVI can be performed offline, this method is dependent on image quality.

Objective: To assess the relative contribution of each myocardial segment to global systolic function during stress using real time three-dimensional echocardiography (RT3DE). Background: During stress, global augmentation in contractility results in an increased stroke volume. The relative contribution of each myocardial segment to these volumetric changes is unknown. Methods: Full volume was acquired using RT3DE at rest and following peak exercise in 22 patients who had no ischemia and no systolic dyssynchrony on two-dimensional (2D) stress echocardiography. The following were calculated at rest and peak stress: end-diastolic volume (EDV), end-systolic volume (ESV), stroke volume (SV), ejection fraction (EF), relative SV, and relative EF. Results: With stress, an increase in global EDV from 90.8 to 101.1 ml (P < 0.001), SV from 59 to 78.4 ml (P = 0.01), and EF from 65.6 to 78.4% (P = 0.001) was observed. ESV decreased from 31.8 to 22.7 ml (P < 0.001). Segmental analysis revealed significantly higher SV, relative SV, and relative EF for the basal anterior, basal anterolateral, and basal inferolateral segments compared with the apical septum and apical inferior segments at both rest and stress (P < 0.001). The SV, relative SV, and relative EF increased significantly from apex to mid to base at both rest and stress (P < 0.001). Conclusions: The relative volumetric contribution of each myocardial segment to global left ventricular systolic function at rest and stress is not uniform. The basal segments contribute more than the mid and apical segments. Specifically, the basal anterior, basal anterolateral, and basal inferolateral segments contribute the most to augmentation of left ventricular systolic function with exercise.

Objectives To measure the prevalence and incidence of delirium in older adults as they transition from the emergency department (ED) to the inpatient ward, and to determine the association between delirium during early hospitalisation and subsequent clinical deterioration. Design Prospective cohort study. Setting Urban tertiary care hospital in Bronx, New York. Participants Adults aged 65 years or older admitted to the inpatient ward from the ED (n=260). Measurements Beginning in the ED, delirium was assessed daily for 3 days, using the Confusion Assessment Method for the Intensive Care Unit. Outcomes (1) Clinical deterioration, defined as unanticipated intensive care unit (ICU) admission or in-hospital death (primary outcome); (2) decline in discharge status, defined as discharge to higher level of care, hospice or in-hospital death. Results 38 of 260 participants (15%) were delirious at least once during the first 3 days of hospitalisation. Of the 29 (11%) patients with delirium in the ED (ie, hospital day 1), delirium persisted into hospital day 2 in 72% (n=21), and persisted for all 3 days in 52% (n=15). In multivariate analyses, as little as 1 episode of delirium during the first 3 days was associated with increased odds of unanticipated ICU admission or in-hospital death (adjusted OR 8.07 (95% CI 1.91 to 34.14); p=0.005). Delirium that persisted for all 3 days was associated with a decline in discharge status, even after adjusting for factors such as severity of illness and baseline cognitive impairment (adjusted OR 4.70 (95% CI 1.41 to 15.63); p=0.012). Conclusions Delirium during the first few days of hospitalisation was associated with poor outcomes in older adults admitted from the ED to the inpatient ward. These findings suggest the need for serial delirium monitoring that begins in the ED to identify a high-risk population that may benefit from closer follow-up and intervention.
