Abstract Background: The dysregulation of the heart rate circadian rhythm has been documented to be an independent risk factor in multiple diseases. However, data showing the impact of dysregulated heart rate circadian rhythm in stroke and critically ill patients are scarce.Methods: Stroke and critically ill patients in the ICU between 2014 and 2015 from the recorded eICU Collaborative Research Database were included in the current analyses. The impact of circadian rhythm of heart rate on in-hospital mortality was analyzed. Three variables, Mesor (rhythm-adjusted mean of heart rate), Amplitude (distance from the highest point of circadian rhythm of heart rate to Mesor), and Peak time (time when the circadian rhythm of heart rate reaches the highest point) were used to evaluate the heart rate circadian rhythm. The incremental value of circadian rhythm variables in addition to Acute Physiology and Chronic Health Evaluation (APACHE) IV score to predict in-hospital mortality was also explored.Results: A total of 6,201 eligible patients were included. The in-hospital mortality was 16.2% (1,002/6,201). The circadian rhythm variables of heart rate, Mesor, Amplitude, and Peak time, were identified to be independent risk factors of in-hospital mortality. After adjustments, Mesor per 10 beats per min (bpm) increase was associated with a 1.17-fold (95%CI: 1.11, 1.24, P<0.001) and Amplitude per 5 bpm was associated with a 1.14-fold (95%CI: 1.06, 1.24, P<0.001) increase in the risk of in-hospital mortality, respectively. The risk of in-hospital mortality was lower in patients who had Peak time reached between 18:00-24:00 or 00:00-06:00; whereas the risk was highest in patients who had Peak time reached between 12:00-18:00 (OR: 1.33, 95%CI: 1.05, 1.68, P=0.017). Compared with APACHE IV score only (c-index=0.757), combining APACHE IV score and circadian rhythm variables of heart rate (c-index=0.766) was associated with increased discriminative ability (P=0.003).Conclusion: Circadian rhythm of heart rate is an independent risk factor of the in-hospital mortality in stroke and critically ill patients. Including circadian rhythm variables regarding heart rate might increase the discriminative ability of the risk score to predict the short-term prognosis of patients.

The Impact

Background: Coronavirus disease 2019 (COVID-19) has become one of the leading causes of death worldwide. The impact of poor nutritional status on increased mortality and prolonged ICU (intensive care unit) stay in critically ill patients is well-documented. This study aims to assess how nutritional status and BMI (body mass index) affected in-hospital mortality in critically ill COVID-19 patients Methods: We conducted a retrospective study and analysed medical records of 286 COVID-19 patients admitted to the intensive care unit of the University Clinical Hospital in Wroclaw (Poland). Results: A total of 286 patients were analysed. In the sample group, 8% of patients who died had a BMI within the normal range, 46% were overweight, and 46% were obese. There was a statistically significantly higher death rate in men (73%) and those with BMIs between 25.0–29.9 (p = 0.011). Nonsurvivors had a statistically significantly higher HF (Heart Failure) rate (p = 0.037) and HT (hypertension) rate (p < 0.001). Furthermore, nonsurvivors were statistically significantly older (p < 0.001). The risk of death was higher in overweight patients (HR = 2.13; p = 0.038). Mortality was influenced by higher scores in parameters such as age (HR = 1.03; p = 0.001), NRS2002 (nutritional risk score, HR = 1.18; p = 0.019), PCT (procalcitonin, HR = 1.10; p < 0.001) and potassium level (HR = 1.40; p = 0.023). Conclusions: Being overweight in critically ill COVID-19 patients requiring invasive mechanical ventilation increases their risk of death significantly. Additional factors indicating a higher risk of death include the patient’s age, high PCT, potassium levels, and NRS ≥ 3 measured at the time of admission to the ICU.

Purpose: To assess the impact of rapid muscle loss before admission to intensive care unit (ICU) in critically ill patients with cirrhosis. Materials and Methods: Patients with cirrhosis who had undergone 2 or more recent computed tomography scans before admission to the medical ICU were included. Muscle cross-sectional area at the level of the third lumbar vertebra was quantified using OsiriX software. The rate of muscle mass change and skeletal muscle index (SMI) were also calculated. Multivariable Cox proportional hazards regression was used to evaluate the association between muscle loss and mortality. Results: Among 125 patients, 113 (90.4%) patients were classified as having sarcopenia. The mean body mass index was 22.6 (3.9) kg/m2. Thirty-nine (31.2%) patients were within the normal range for muscle mass change, while 86 (68.8%) patients demonstrated rapid decline in muscle mass before admission to the ICU. Patients with rapid muscle loss showed high ICU mortality (59.3%) and in-hospital mortality (77.9%). Multivariate Cox analysis showed that ICU mortality and in-hospital mortality were independently associated with malignancy, Acute Physiology and Chronic Health Evaluation (APACHE) II score, SMI, and rapid muscle loss. Conclusion: Rapid muscle decline is correlated with increased ICU mortality and in-hospital mortality in critically ill patients with cirrhosis.

Elevated Heart Rate

Abstract Background Heart rate is routinely measured in Neurological intensive care unit(NICU), but its prognostic value remains debated. We sought to evaluate the association of high cumulative numbers of elevated Heart Rate (HcneHR) with mortality in NICU patients. Methods We used a large observational eICU Collaborative Research Database (eICU-CRD), where continous heart rate monitoring every 5 minute was available. We collected periodic heart rate, disease severity (APACHE IV score), NICU and hospital mortality and other information in 8347 patient admissions from the eICU-CRD. The cumulative numbers of Heart Rate (cneHR) were defined as >100 beats/min in first admittion 24 hours, and if cneHR ≥10,then was defined as higt cneHR(HcneHR). The primary outcome was NICU mortality. The other outcomes were hospital mortality, length of NICU stay and APACHE IV score. Multivariable logistic regression was used to assess for association for HcneHR and other covariance with NICU and hospiltal discharge status. Results The mean age of patients were 63 years, and the most frequent disease categories of NICU in eICU-CRD were postoperation (25%), stroke(19%), traumatic brain injury(14%). The mean APACHE IV score was 50. Overall NICU mortality of the cohort at discharge was 4%, and hospital mortality was 8%. The NICU mortality of HcneHR patients was 7%. Adjusted logistic regression for HcneHR showed a significantly increased risk of NICU death with odds ratio 1.61(confidence interval, 1.26-2.06; P <0 .001). Conclusions In adult neurocritically ill patients, we found a significant association for HcneHR with elevated mortality and several others important patient-centered outcomes.

Abstract Background Invasive fungal infections (IFIs), though uncommon, are on the rise and have a high mortality rate. Fungal colonization is common, but its clinical significance is unclear. Our study aims to characterize the impact of these diagnoses and their management on outcomes in a large ICU population. Methods We utilized the Multiparameter Intelligent Monitoring in Intensive Care III database for this retrospective cohort study. Adults with positive fungal cultures were classified as colonized or infected using definitions from the EORTC/MSG guidelines and the Blot protocol for Aspergillus. Outcomes were compared between groups matched by age, SOFA score, admission diagnosis, culture results, and comorbidities. Results There were 595 hospital admissions with IFI (11.7/1000 admissions) and 5789 with colonization (114/1000 admissions). In-hospital mortality was 52% in patients with IFIs and 36% in colonized patients. Mortality post-discharge remained high and was not significantly different in the two groups. 67% of patients with IFIs had the diagnosis documented. 24% of patients with IFIs and 8% of colonized patients received antifungal therapy. Treatment did not significantly impact mortality in infected or colonized patients but was associated with increased length of hospital and ICU stay. Infectious disease (ID) consultation was performed in 39.8% of patients with IFIs and 20% of patients with colonization. In the group of IFI patients with ID consultation, in-hospital mortality was higher, but survival post-discharge increased significantly. There was a significant increase in diagnosis of IFI in the ID group and a trend toward increased treatment. In colonized patients with ID consultation, in-hospital mortality and survival post-discharge improved. Hospital and ICU length of stay were longer for patients with ID consultation. Conclusion Critically ill patients with IFIs have high mortality rates, which were not reduced by treatment. The prevalence of colonization was high, and colonized patients experienced significant in-hospital and post-discharge mortality. This study supports the need for additional investigation into ID consultation, which may improve outcomes in critically ill patients with fungal infection and colonization.

Abstract Background Remdesivir (RDV), was included for the treatment of mild to moderate COVID-19 since July 2020 in our institution, following the initial results from ACTT-1 interim analysis report. With the adoption of RDV, there seems to be anecdotal evidence of efficacy as evidenced by early fever defervescence, quick recovery when on oxygen with decreased need for ventilation and ICU care. We aimed to study the impact of RDV on clinical outcomes among patients with moderate to severe COVID –19. Methods Nested case control study in the cohort of consecutive patients with moderate to severe COVID – 19. Cases were patients initiated on RDV and age and sex- matched controls who did not receive RDV were included. The primary outcome was in-hospital mortality. Secondary outcomes were, duration of hospital stay, need for ICU, duration of oxygen therapy and need for ventilation. Results A total of 926 consecutive patients with COVID – 19 were included, among which 411 patients were cases and 515 controls. The mean age of the cohort was 57.05±13.5 years, with male preponderance (75.92%). The overall in-hospital mortality was 22.46%(n=208). On comparison between cases and controls there was no statistically significant difference with respect to primary outcome [22.54% vs. 20.78%, (p value: 0.17)]. Progression to non-invasive ventilation (NIV) was higher among the controls [24.09% vs. 40.78% (p value: &lt; 0.001*)]. Progression to invasive ventilation was also higher among the controls [5.35% vs. 9.71% (p value: 0.014*)]. In subgroup analysis among critically ill patients, the use of RDV showed decrease in mortality (OR 0.32 95% CI; 0.13 – 0.75 p value – 0.009*). Conclusion RDV did not decrease the in-hospital mortality among moderate to severe COVID – 19. However, there seems to be a significant reduction in mortality in critically ill patients.

Abstract Background: The association of pre-existing diabetes mellitus and outcomes among critically ill patients remains unknown.Methods: This retrospective study enrolled patients who were covered by the eICU Collaborative Research Database from 2014 to 2015. DM was the exposure of interest, and diabetic individuals were adjudicated by the medical history, and blood glucose level (BGL). We abstracted basic characteristics, laboratory variables, and primary exposures. ICU mortality was the primary outcome.Results: In a cohort of 134,429 critically ill patients (male 54.4%, median age 66 [54-77] years, BMI 28[24-33] kg/m2), the prevalence of DM was 29%. In comparison with nondiabetics, DM patients were older, more obese, had higher Acute Physiology and Chronic Health Evaluation (APACHE)-IV score, and ICU admission BGL. In comparison with nondiabetics, pre-existing DM was associated with lower ICU mortality (OR: 0.846, 95%CI: 0.791-0.905). In multivariable logistic regression and Cox proportional hazard analyses, pre-existing DM was associated with decreased odds of ICU mortality in hyperglycemic patients (>163 mg/dL), higher APACHE IV score (>67), middle to old age (45-75 years), sepsis and morbid obesity (BMI>35 kg/m2). Also, in comparison with nondiabetics, pre-existing DM was associated with lower mortality among those with higher mean BGL (>128 mg/dL), and higher mortality in lower mean BGL (<107 mg/dL). Conclusions: In comparison with nondiabetics, pre-existing DM is associated with a lower adjusted ICU mortality. This association is stronger in DM patients with hyperglycemia, obesity, sepsis, middle to old age, and higher APACHE IV score.

Statin Use

Abstract Purpose The complications of Severe Corona Virus Disease 2019 (COVID-19) are attributed to the overproduction of early response proinflammatory cytokines, causing a systemic hyperinflammatory state. Statins are potentially a potent adjuvant therapy in COVID-19 infection due to their pleiotropic and anti-inflammatory effects, which are independent of their cholesterol-lowering activity. This study investigates the impact of statin use on the outcome of critically ill patients with COVID-19. Methods A multicenter, retrospective cohort study of all adult critically ill patients with confirmed COVID-19 admitted to Intensive Care Units (ICUs) between March 1, 2020, and March 31, 2021. Eligible patients were classified into two groups based on statin use during ICU stay and were matched with a propensity score which was based on patient’s age and admission APACHE II and SOFA scores. The primary endpoint was in-hospital mortality. Other outcomes were considered secondary... Results A total of 1049 patients were eligible; 502 patients were included after propensity score matching (1:1 ratio). The 30-day (hazard ratio 0.75 (95% CI 0.58, 0.98), P = 0.03) and in-hospital mortality (hazard ratio 0.69 (95% CI 0.54, 0.89), P = 0.004) were significantly lower in patients who received statin therapy on multivariable cox proportional hazards regression analysis. Moreover, patients who received statin have a lower risk of hospital-acquired pneumonia (OR 0.48(95% CI 0.32, 0.69), P = < 0.001), lower levels of markers of inflammation on follow up and no increased risk of liver injury. Conclusion The use of statin during ICU stay in COVID-19 critically ill patients may have a beneficial role and survival benefits with a good safety profile.
