AbstractAbstract PDFSupplementary Material
The main mechanism of Takotsubo cardiomyopathy (TCM) is catecholamine-induced acute myocardial stunning. Pheochromocytoma, a catecholamine-secreting tumor, can cause several cardiovascular complications, including hypertensive crisis, myocardial infarction, toxic myocarditis, and TCM. A 29-year-old woman presented to our hospital with general weakness, vomiting, dyspnea, and chest pain. The patient was nullipara, 28 weeks’ gestation, and had a cachexic morphology. Her cardiac enzyme levels were elevated and bedside echocardiography showed apical akinesia, suggesting TCM. The next day, she could not feel the fetal movement, and an emergency cesarean section was performed. After delivery, the patient experienced cardiac arrest and was transferred to the intensive care unit for cardiopulmonary resuscitation (CPR). Spontaneous circulation returned after 28 minutes of CPR, but cardiogenic shock continued, and extracorporeal membrane oxygenation (ECMO) was initiated. On the third day of ECMO maintenance, left ventricular ejection fraction improved and blood pressure stabilized. On the eighth day after ECMO insertion, it was removed. However, complications of the left leg vessels occurred, and several surgeries and interventions were performed. A left adrenal gland mass was found on computed tomography and was removed while repairing the leg vessels. Pheochromocytoma was diagnosed and left adrenalectomy was performed.

AbstractAbstract PDF
Background
Identifying critically ill patients at risk of cardiac arrest is important because it offers the opportunity for early intervention and increased survival. The aim of this study was to develop a deep learning model to predict critical events, such as cardiopulmonary resuscitation or mortality. Methods: This retrospective observational study was conducted at a tertiary university hospital. All patients younger than 18 years who were admitted to the pediatric intensive care unit from January 2010 to May 2023 were included. The main outcome was prediction performance of the deep learning model at forecasting critical events. Long short-term memory was used as a deep learning algorithm. The five-fold cross validation method was employed for model learning and testing. Results: Among the vital sign measurements collected during the study period, 11,660 measurements were used to develop the model after preprocessing; 1,060 of these data points were measurements that corresponded to critical events. The prediction performance of the model was the area under the receiver operating characteristic curve (95% confidence interval) of 0.988 (0.9751.000), and the area under the precision-recall curve was 0.862 (0.700–1.000). Conclusions: The performance of the developed model at predicting critical events was excellent. However, follow-up research is needed for external validation.

AbstractAbstract PDF
Background
Pneumonia frequently leads to intensive care unit (ICU) admission and is associated with a high mortality risk. This study aimed to assess the impact of early bronchoscopy administered within 3 days of ICU admission on mortality in patients with pneumonia using the Medical Information Mart for Intensive Care-IV (MIMIC-IV) database. Methods: A single-center retrospective analysis was conducted using the MIMIC-IV data from 2008 to 2019. Adult ICU-admitted patients diagnosed with pneumonia were included in this study. The patients were stratified into two cohorts based on whether they underwent early bronchoscopy. The primary outcome was the 28-day mortality rate. Propensity score matching was used to balance confounding variables. Results: In total, 8,916 patients with pneumonia were included in the analysis. Among them, 783 patients underwent early bronchoscopy within 3 days of ICU admission, whereas 8,133 patients did not undergo early bronchoscopy. The primary outcome of the 28-day mortality between two groups had no significant difference even after propensity matched cohorts (22.7% vs. 24.0%, P=0.589). Patients undergoing early bronchoscopy had prolonged ICU (P<0.001) and hospital stays (P<0.001) and were less likely to be discharged to home (P<0.001). Conclusions: Early bronchoscopy in severe pneumonia patients in the ICU did not reduce mortality but was associated with longer hospital stays, suggesting it was used in more severe cases. Therefore, when considering bronchoscopy for these patients, it's important to tailor the decision to each individual case, thoughtfully balancing the possible advantages with the related risks.

AbstractAbstract PDF
Background
Studies on the association between pleural effusion (PE) and left ventricular assist devices (LVADs) are limited. This study aimed to examine the characteristics and the clinical impact of PE following LVAD implantation. Methods: This study is a prospective analysis of patients who underwent LVAD implantation from June 2015 to December 2022. We investigated the prognostic impact of therapeutic drainage (TD) on clinical outcomes. We also compared the characteristics and clinical outcomes between early and late PE and examined the factors related to the development of late PE. Results: A total of 71 patients was analyzed. The TD group (n=45) had a longer ward stay (days; median [interquartile range]: 31.0 [23.0–46.0] vs. 21.0 [16.0–34.0], P=0.006) and total hospital stay (47.0 [36.0–82.0] vs. 31.0 [22.0–48.0], P=0.002) compared to the no TD group (n=26). Early PE was mostly exudate, left-sided, and neutrophil-dominant even though predominance of lymphocytes was the most common finding in late PE. Patients with late PE had a higher rate of reintubation within 14 days (31.8% vs. 4.1%, P=0.004) and longer hospital stays than those without late PE (67.0 [43.0–104.0] vs. 36.0 [28.0–48.0], P<0.001). Subgroup analysis indicated that female sex, low body mass index, cardiac resynchronization therapy, and hypoalbuminemia were associated with late PE. Conclusions: Compared to patients not undergoing TD, those undergoing TD had a longer hospital stay but not a higher 90-day mortality. Patients with late PE had poor clinical outcomes. Therefore, the correction of risk factors, like hypoalbuminemia, may be required.

AbstractAbstract PDF
Background
Using peripheral arteries to infer central hemodynamics is common among hemodynamic monitors. Doppler ultrasound of the common carotid artery has been used in this manner with conflicting results. We investigated the relationship between changing common carotid artery Doppler measures and stroke volume (SV), hypothesizing that more consecutively-averaged cardiac cycles would improve SV-carotid Doppler correlation. Methods: Twenty-seven healthy volunteers were recruited and studied in a physiology laboratory. Carotid artery Doppler pulse was measured with a wearable, wireless ultrasound during central hypovolemia and resuscitation induced by a stepped lower body negative pressure protocol. The change in maximum velocity time integral (VTI) and corrected flow time of the carotid artery (ccFT) were compared with changing SV using repeated measures correlation. Results: In total, 73,431 cardiac cycles were compared across 27 subjects. There was a strong linear correlation between changing SV and carotid Doppler measures during simulated hemorrhage (repeated-measures linear correlation [Rrm ]=0.91 for VTI; 0.88 for ccFT). This relationship improved with larger numbers of consecutively-averaged cardiac cycles. For ccFT, beyond four consecutively-averaged cardiac cycles the correlation coefficient remained strong (i.e., Rrm of at least 0.80). For VTI, the correlation coefficient with SV was strong for any number of averaged cardiac cycles. For both ccFT and VTI, Rrm remained stable around 25 consecutively-averaged cardiac cycles. Conclusions: There was a strong linear correlation between changing SV and carotid Doppler measures during central blood volume loss. The strength of this relationship was dependent upon the number of consecutively-averaged cardiac cycles.

AbstractAbstract PDF
Background
Optic nerve sheath diameter (ONSD) is an emerging non-invasive, easily accessible, and possibly useful measurement for evaluating changes in intracranial pressure (ICP). The utilization of bedside ultrasonography (USG) to measure ONSD has garnered increased attention due to its portability, real-time capability, and lack of ionizing radiation. The primary aim of the study was to assess whether bedside USG-guided ONSD measurement can reliably predict increased ICP in traumatic brain injury (TBI) patients. Methods: A total of 95 patients admitted to the trauma intensive care unit was included in this cross sectional study. Patient brain computed tomography (CT) scans and Glasgow Coma Scale (GCS) scores were assessed at the time of admission. Bedside USG-guided binocular ONSD was measured and the mean ONSD was noted. Microsoft Excel was used for statistical analysis. Results: Patients with low GCS had higher mean ONSD values (6.4±1.0 mm). A highly significant association was found among the GCS, CT results, and ONSD measurements (P<0.001). Compared to CT scans, the bedside USG ONSD had 86.42% sensitivity and 64.29% specificity for detecting elevated ICP. The positive predictive value of ONSD to identify elevated ICP was 93.33%, and its negative predictive value was 45.00%. ONSD measurement accuracy was 83.16%. Conclusions: Increased ICP can be accurately predicted by bedside USG measurement of ONSD and can be a valuable adjunctive tool in the management of TBI patients.

AbstractAbstract PDF
Background
Platelet-to-Lymphocyte ratio (PLR) has been studied as a prognostic factor for various diseases and traumas. This study examined the utility of PLR as a tool for predicting 30-day mortality in patients experiencing severe trauma. Methods: This study included 139 patients who experienced trauma and fulfilled ≥1 criteria for activation of the hospital’s severe trauma team. Patients were divided into non-survivor and survivor groups. Mean PLR values were compared between the groups, the optimal PLR cut-off value was determined, and mortality and survival analyses were performed. Statistical analyses were performed using SPSS ver. 26.0. The threshold of statistical significance was P<0.05. Results: There was a significant difference in mean (±standard deviation) PLR between the non-survivor (n=36) and survivor (n=103) groups (53.4±30.1 vs. 89.9±53.3, respectively; P<0.001). Receiver operating characteristic (ROC) curve analysis revealed an optimal PLR cut-off of 65.35 (sensitivity, 0.621; specificity, 0.694, respectively; area under the ROC curve, 0.742), and Kaplan-Meier survival analysis revealed a significant difference in mortality rate between the two groups. Conclusions: PLR can be calculated quickly and easily from a routine complete blood count, which is often performed in the emergency department for individuals who experience trauma. The PLR is useful for predicting 30-day mortality in trauma patients with severe trauma team activation.

Background
Medical complications in peripartum patients are uncommon. Often, these patients are transferred to tertiary care centers, but their conditions and outcomes are not well understood. Our study examined peripartum patients transferred to an intensive care unit (ICU) at an academic quaternary center. Methods: We reviewed charts of adult, non-trauma, interhospital transfer (IHT) peripartum patients sent to an academic quaternary ICU between January 2017 and December 2021. We conducted a descriptive analysis and used multivariable ordinal regression to examine associations of demographic and clinical factors with ICU length of stay (LOS) and hospital length of stay (HLOS). Results: Of 1,794 IHT peripartum patients, 60 (3.2%) were directly transferred to an ICU. The average was 32 years, with a median Sequential Organ Failure Assessment (SOFA) score of 3 (1–4.25) and Acute Physiology and Chronic Health Evaluation (APACHE) II score of 8 (7–12). Respiratory failure was most common (32%), followed by postpartum hemorrhage (15%) and sepsis (14%). Intubation was required for 24 (41%), and 4 (7%) needed extracorporeal membrane oxygenation. Only 1 (1.7%) died, while 45 (76.3%) were discharged. Median ICU LOS and HLOS were 5 days (212) and 8 days (5–17). High SOFA score was linked to longer HLOS, as was APACHE II. Conclusions: Transfers of critically ill peripartum patients between hospitals were rare but involved severe medical conditions. Despite this, their outcomes were generally positive. Larger studies are needed to confirm our findings.

Background
The Controlling Nutritional Status (CONUT) score and the prognostic nutritional index (PNI) have emerged as important nutritional indices because they provide an objective assessment based on data. We aimed to investigate how these nutritional indices relate to outcomes in patients with sepsis. Methods: Data were collected retrospectively at five hospitals for patients aged ≥18 years receiving treatment for sepsis between January 1, 2017, and December 31, 2021. Serum albumin and total cholesterol concentrations, and peripheral lymphocytes were used to calculate the CONUT score and PNI. To identify predictors correlated with 30-day mortality, analyses were conducted using univariate and multivariate Cox proportional hazards models. Results: The 30-day mortality rate among 9,763 patients was 15.8% (n=1,546). The median CONUT score was 5 (interquartile range [IQR], 3–7) and the median PNI score was 39.6 (IQR, 33.846.4). Higher 30-day mortality rates were associated with individuals with moderate (CONUT score: 5–8; PNI: 35–38) or severe (CONUT: 9–12; PNI: <35) malnutrition compared with those with no malnutrition (CONUT: 0–1; PNI: >38). With CONUT scores, the hazard ratio (HR) associated with moderate malnutrition was 1.52 (95% confidence interval [CI], 1.24–1.87; P<0.001); for severe, HR=2.42 (95% CI, 1.95–3.02; P<0.001). With PNI scores, the HR for moderate malnutrition was 1.29 (95% CI, 1.09–1.53; P=0.003); for severe, HR=1.88 (95% CI, 1.67–2.12; P<0.001). Conclusions: The nutritional indices CONUT score and PNI showed significant associations with mortality of sepsis patients within 30 days.

AbstractAbstract PDF
Background
Point of care ultrasound (POCUS) is being explored for dynamic measurements like inferior vena cava collapsibility index (IVC-CI) and left ventricular outflow tract velocity time integral (LVOT-VTI) to guide anesthesiologists in predicting fluid responsiveness in the preoperative period and in treating post-induction hypotension (PIH) with varying accuracy. Methods: In this prospective, observational study on included 100 adult patients undergoing elective surgery under general anesthesia, the LVOT-VTI and IVC-CI measurements were performed in the preoperative room 15 minutes prior to surgery, and PIH was measured for 20 minutes in the post-induction period. Results: The incidence of PIH was 24%. The area under the curve, sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of the two techniques at 95% confidence interval was 0.613, 30.4%, 93.3%, 58.3%, 81.4%, 73.6% for IVC-CI and 0.853, 83.3%, 80.3%, 57.1%, 93.8%, 77.4% for LVOT-VTI, respectively. In multivariate analysis, the cutoff value for IVC-CI was >51.5 and for LVOT-VTI it was ≤17.45 for predicting PIH with odd ratio [OR] of 8.491 (P=0.025) for IVCCI and OR of 17.427 (P<0.001) for LVOT. LVOT-VTI assessment was possible in all the patients, while 10% of patients were having poor window for IVC measurements. Conclusions: We recommend the use of POCUS using LVOT-VTI or IVC-CI to predict PIH, to decrease the morbidity of patients undergoing surgery. Out of these, we recommend LVOT-VTI measurements as it has showed a better diagnostic accuracy (77.4%) with no failure rate.

Background
In this study, we reviewed the outcomes of pediatric patients with malignancies who underwent hematopoietic stem cell transplantation (HSCT) and extracorporeal membrane oxygenation (ECMO). Methods: We retrospectively analyzed the records of pediatric hemato-oncology patients treated with chemotherapy or HSCT and who received ECMO in the pediatric intensive care unit (PICU) at Seoul National University Children’s Hospital from January 2012 to December 2020. Results: Over a 9-year period, 21 patients (14 males and 7 females) received ECMO at a single pediatric institute; 10 patients (48%) received veno-arterial (VA) ECMO for septic shock (n=5), acute respiratory distress syndrome (ARDS) (n=3), stress-induced myopathy (n=1), or hepatopulmonary syndrome (n=1); and 11 patients (52%) received veno-venous (VV) ECMO for ARDS due to pneumocystis pneumonia (n=1), air leak (n=3), influenza (n=1), pulmonary hemorrhage (n=1), or unknown etiology (n=5). All patients received chemotherapy; 9 received anthracycline drugs and 14 (67%) underwent HSCT. Thirteen patients (62%) were diagnosed with malignancies and 8 (38%) were diagnosed with non-malignant disease. Among the 21 patients, 6 (29%) survived ECMO in the PICU and 5 (24%) survived to hospital discharge. Among patients treated for septic shock, 3 of 5 patients (60%) who underwent ECMO and 5 of 10 patients (50%) who underwent VA ECMO survived. However, all the patients who underwent VA ECMO or VV ECMO for ARDS died. Conclusions: ECMO is a feasible treatment option for respiratory or heart failure in pediatric patients receiving chemotherapy or undergoing HSCT.
