Evaluation of the Impact of ABCDEF Bundle Compliance Rates on Postintensive Care Syndrome: A Secondary Analysis Study.

OBJECTIVES: This study aimed to examine the association between ABCDEF bundles and long-term postintensive care syndrome (PICS)-related outcomes. DESIGN: Secondary analysis of the J-PICS study. SETTING: This study was simultaneously conducted in 14 centers and 16 ICUs in Japan between April 1, 2019, and September 30, 2019. PATIENTS: Adult ICU patients who were expected to be on a ventilator for at least 48 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Bundle compliance for the last 24 hours was recorded using a checklist at 8:00 am The bundle compliance rate was defined as the 3-day average of the number of bundles performed each day divided by the total number of bundles. The relationship between the bundle compliance rate and PICS prevalence (defined by the 36-item Short Form Physical Component Scale, Mental Component Scale, and Short Memory Questionnaire) was examined. A total of 191 patients were included in this study. Of these, 33 patients (17.3%) died in-hospital and 48 (25.1%) died within 6 months. Of the 96 patients with 6-month outcome data, 61 patients (63.5%) had PICS and 35 (36.5%) were non-PICS. The total bundle compliance rate was 69.8%; the rate was significantly lower in the 6-month mortality group (66.6% vs 71.6%, p = 0.031). Bundle compliance rates in patients with and without PICS were 71.3% and 69.9%, respectively ( p = 0.61). After adjusting for confounding variables, bundle compliance rates were not significantly different in the context of PICS prevalence ( p = 0.56). A strong negative correlation between the bundle compliance rate and PICS prevalence ( r = -0.84, R 2 = 0.71, p = 0.035) was observed in high-volume centers. CONCLUSIONS: The bundle compliance rate was not associated with PICS prevalence. However, 6-month mortality was lower with a higher bundle compliance rate. A trend toward a lower PICS prevalence was associated with higher bundle compliance in high-volume centers.

Prevalence of post-intensive care syndrome among Japanese intensive care unit patients: a prospective, multicenter, observational J-PICS study.

BACKGROUND: Many studies have compared quality of life of post-intensive care syndrome (PICS) patients with age-matched population-based controls. Many studies on PICS used the 36-item Short Form (SF-36) health survey questionnaire version 2, but lack the data for SF-36 values before and after intensive care unit (ICU) admission. Thus, clinically important changes in the parameters of SF-36 are unknown. Therefore, we determined the frequency of co-occurrence of PICS impairments at 6 months after ICU admission. We also evaluated the changes in SF-36 subscales and interpreted the patients' subjective significance of impairment. METHODS: A prospective, multicenter, observational cohort study was conducted in 16 ICUs across 14 hospitals in Japan. Adult ICU patients expected to receive mechanical ventilation for > 48 h were enrolled, and their 6-month outcome was assessed using the questionnaires. PICS definition was based on the physical status, indicated by the change in SF-36 physical component score (PCS) ≥ 10 points; mental status, indicated by the change in SF-36 mental component score (MCS) ≥ 10 points; and cognitive function, indicated by the worsening of Short-Memory Questionnaire (SMQ) score and SMQ score at 6 months < 40. Multivariate logistic regression model was used to identify the factors associated with PICS occurrence. The patients' subjective significance of physical and mental symptoms was assessed using the 7-scale Global Assessment Rating to evaluate minimal clinically important difference (MCID). RESULTS: Among 192 patients, 48 (25%) died at 6 months. Among the survivors at 6 months, 96 patients responded to the questionnaire; ≥ 1 PICS impairment occurred in 61 (63.5%) patients, and ≥ 2 occurred in 17 (17.8%) patients. Physical, mental, and cognitive impairments occurred in 32.3%, 14.6% and 37.5% patients, respectively. Population with only mandatory education was associated with PICS occurrence (odds ratio: 4.0, 95% CI 1.1-18.8, P = 0.029). The MCID of PCS and MCS scores was 6.5 and 8.0, respectively. CONCLUSIONS: Among the survivors who received mechanical ventilation, 64% had PICS at 6 months; co-occurrence of PICS impairments occurred in 20%. PICS was associated with population with only mandatory education. Future studies elucidating the MCID of SF-36 scores among ICU patients and standardizing the PICS definition are required.

Comparison of the Incidence of Post-intensive Care Syndrome (PICS) Between Elderly and Non-elderly Patients: A Subgroup Analysis of the Japan-PICS Study.

AIM: The aging society is expanding, and more elderly patients are admitted to intensive care units (ICUs). Elderly patients may have increased ICU mortality and are thought to have a high incidence of post-intensive care syndrome (PICS). There are few studies of PICS in the elderly. This study hypothesized that the elderly have an increased incidence of PICS compared to the non-elderly. METHODS: This is a subgroup analysis of a previous multicenter prospective observational study (Prevalence of post-intensive care syndrome among Japanese intensive care unit patients: The Japan-PICS study) conducted from April 2019 to September 2019. Ninety-six patients were included who were over 18 years old, admitted to the ICU, and expected to require mechanical ventilation for more than 48 hours. Physical component scales (PCS), mental component scales (MCS), and Short-Memory Questionnaire (SMQ) scores of included patients were compared before admission to the ICU and six months later. The diagnosis of PICS required one of the following: (1) the PCS score decreased ≧10 points, (2) the MCS score decreased ≧10 points, or (3) the SMQ score decreased by >40 points. Patients were classified as non-elderly (<65 years old) or elderly (≧65 years old), and the incidence of PICS was compared between these two groups. RESULTS: The non-elderly (N=27) and elderly (N=69) groups had incidences of PICS: 67% and 62% (p=0.69), respectively. CONCLUSION: There is no statistically significant difference in the incidence of PICS in the non-elderly and elderly.

Low SARS-CoV-2 antibody titers may be associated with poor clinical outcomes for patients with severe COVID-19.

Recently, immune response to coronavirus disease (COVID-19) has attracted attention where an association between higher antibody titer and worsening disease severity has been reported. However, our experiences with severe COVID-19 patients with low antibody titers led to hypothesizing that suppressed humoral immune response may be associated with poorer prognosis in severe COVID19. In this study, antibody titers in severe COVID19 patients were measured at 7, 10, 12, and 14 days after onset. Patients were divided into survivors and non-survivors. SARS-CoV-2 IgM in survivors and non-survivors were 0.06 AU and 0.02 AU (P = 0.048) at 10 days, 0.1 AU and 0.03 AU (P = 0.02) at 12 days, and 0.17 AU and 0.06 AU (P = 0.02) at 14 days. IgG in survivors and non-survivors were 0.01 AU and 0.01 AU (P = 0.04) at 7 days, 0.42 AU and 0.01 AU (P = 0.04) at 12 days, and 0.42 AU and 0.01 AU (P = 0.02) at 14 days. Multivariate analysis showed better survival among patients with IgM positivity at 12 days (P = 0.04), IgG positivity at 12 days (P = 0.04), IgM positivity at 14 days (P = 0.008), and IgG positivity at 14 days (P = 0.005). In severe COVID-19, low antibody titers on days 12 and 14 after onset were associated with poorer prognosis.

Serum gasdermin D levels are associated with the chest computed tomography findings and severity of COVID-19.

BACKGROUND: The role of programmed cell death, especially pyroptosis and apoptosis, in unfavorable immune responses in COVID-19 remains to be elucidated. METHODS: We conducted a cross-sectional analysis to investigate the association between the serum gasdermin D (GSDMD) levels, a pyroptotic marker, and caspase-cleaved cytokeratin 18 fragment (M30), an apoptotic marker, and the clinical status and abnormal chest computed tomography (CT) findings in patients with COVID-19. RESULTS: In this study, 46 patients diagnosed with COVID-19 were divided into the following three groups according to the disease severity: mild to moderate group (n = 10), severe group (n = 14), and critical group (n = 22). The serum GSDMD levels were higher in the critical group than in the mild to moderate group (P = 0.016). In contrast, serum M30 levels were lower in the critical group than in the severe group (P = 0.048). Patients who required mechanical ventilation or died had higher serum GSDMD levels than those who did not (P = 0.007). Area of consolidation only and of ground glass opacity plus consolidation positively correlated with serum GSDMD levels (r = 0.56, P < 0.001 and r = 0.53, P < 0.001, respectively). CONCLUSION: Higher serum GSDMD levels are associated with critical respiratory status and the consolidation area on chest CT in patients with COVID-19, suggesting that excessive activation of pyroptosis may affect the clinical manifestations in patients with COVID-19.

Predicting the aggravation of coronavirus disease-19 pneumonia using chest computed tomography scans.

Presently, coronavirus disease-19 (COVID-19) is spreading worldwide without an effective treatment method. For COVID-19, which is often asymptomatic, it is essential to adopt a method that does not cause aggravation, as well as a method to prevent infection. Whether aggravation can be predicted by analyzing the extent of lung damage on chest computed tomography (CT) scans was examined. The extent of lung damage on pre-intubation chest CT scans of 277 patients with COVID-19 was assessed. It was observed that aggravation occurred when the CT scan showed extensive damage associated with ground-glass opacification and/or consolidation (p < 0.0001). The extent of lung damage was similar across the upper, middle, and lower fields. Furthermore, upon comparing the extent of lung damage based on the number of days after onset, a significant difference was found between the severe pneumonia group (SPG) with intubation or those who died and non-severe pneumonia group (NSPG) ≥3 days after onset, with aggravation observed when ≥14.5% of the lungs exhibited damage at 3-5 days (sensitivity: 88.2%, specificity: 72.4%) and when ≥20.1% of the lungs exhibited damage at 6-8 days (sensitivity: 88.2%, specificity: 69.4%). Patients with aggravation suddenly developed hypoxemia after 7 days from the onset; however, chest CT scans obtained in the paucisymptomatic phase without hypoxemia indicated that subsequent aggravation could be predicted based on the degree of lung damage. Furthermore, in subjects aged ≥65 years, a significant difference between the SPG and NSPG was observed in the extent of lung damage early beginning from 3 days after onset, and it was found that the degree of lung damage could serve as a predictor of aggravation. Therefore, to predict and improve prognosis through rapid and appropriate management, evaluating patients with factors indicating poor prognosis using chest CT is essential.

Preventing thrombosis in a COVID-19 patient by combined therapy with nafamostat and heparin during extracorporeal membrane oxygenation.

Background: Preventing thrombosis in extracorporeal membrane oxygenation (ECMO) can be life-saving in cases of coronavirus disease (COVID-19); however, circuit thrombosis is a complication. This report describes a COVID-19 patient treated with nafamostat and heparin to prevent circuit thrombosis during ECMO support. Case presentation: A 63-year-old man was transferred to our hospital with respiratory failure due to COVID-19 pneumonia. He was provided venous-venous ECMO to maintain oxygenation. During ECMO support, occlusive circuit thrombosis developed despite systemic anticoagulation therapy with heparin. He was subsequently given combination therapy with nafamostat and heparin. Although the combination therapy could prevent circuit thrombosis, it was converted to heparin monotherapy because of hyperkalemia and hemothorax. After tracheostomy and a gradual improvement in oxygenation, ECMO was discontinued. He was transferred to another hospital for further rehabilitation. Conclusion: Combination therapy with nafamostat and heparin can prevent circuit thrombosis during ECMO. However, bleeding can still develop with this combination therapy during ECMO.

Clinical outcomes of urinary tract infection caused by extended spectrum beta-lactamase producing Enterobacteriaceae: a retrospective observational study comparing patients with and without systemic inflammatory response syndrome.

AIM: In severe urinary tract infection (UTI), susceptible antibiotics should be given. With the recent increase of multidrug-resistant bacteria, especially extended spectrum beta-lactamase producing Enterobacteriaceae (ESBL-E), broad-spectrum antibiotics, such as carbapenems, are used more frequently, which could lead to a further increase of multidrug-resistant bacteria. We aimed to analyze the relationship between initial empirical antibiotic appropriateness and clinical outcomes in UTI, especially in patients with systemic inflammatory response syndrome (SIRS) and ESBL-E. METHODS: A retrospective observational study from 2012 to 2017. RESULTS: Among urine culture-positive cases with ≥105 colony-forming units/mL (n = 1,880), true UTI cases were extracted (n = 844) and divided into the SIRS group (n = 336 [ESBL-E12.8% (43/336)]) and non-SIRS group (n = 508 [ESBL-E12.6% (64/508)]). In the SIRS ESBL-E group, the initial antibiotics were susceptible in 55.8% (24/43), among which 91.7% (22/24) improved and 8.3% (2/24) deteriorated or died. The initial antibiotics were resistant in 44.2% (19/43), among which 47.4% (9/19) improved with the initial antibiotics, 47.4% (9/19) improved after escalating antibiotics, and 5.3% (1/19) deteriorated or died. In the SIRS group, 14 cases had true bacteremia with ESBL-E. Seven cases were initiated with inappropriate antibiotics; four cases showed improvement before or without antibiotic change and three cases improved after antibiotic escalation. CONCLUSION: Initiation of narrow-spectrum antibiotics in septic UTI with ESBL-E might not deteriorate the clinical outcome if promptly escalated on clinical deterioration or with ESBL-E culture results. Further investigation is warranted to guide judicious use of initial antibiotics.

The peripheral lymphocyte count as a predictor of severe COVID-19 and the effect of treatment with ciclesonide.

We investigated whether reduced lymphocyte count, could predict the development of severe COVID-19. We also examined whether ciclesonide could prevent the development of severe COVID-19 among patients with the predictors. This was a retrospective cohort study. Of the 30 included patients, 12, 14, and 4 were allocated to severe pneumonia, non-severe pneumonia, and non-pneumonia groups, respectively. The group of the low level of lymphocyte counts of the sixth day after onset was significantly intubated approximately three days later. The incidence of the severe pneumoniae requiring intubation are significantly lower in the patients treated with ciclesonide than without it (11.18 % vs 83.33 %, p = 0.0033). The lymphocyte count after ciclesonide treatment in the non-severe pneumonia group was significantly higher (p = 0. 0156) than before. The lymphocyte count could be used to identify patients that may develop severe COVID-19. Treatment with ciclesonide may prevent the development of severe COVID-19.
