BACKGROUND
Protein-energy malnutrition is associated with poor surgical outcomes in liver transplant patients, but its impact on healthcare use has not been precisely characterized. We sought to quantify the burden of protein-energy malnutrition in hospitalized patients undergoing liver transplantation.
METHODS
Current Procedural Terminology codes were used to identify United States hospitalizations between 2011 and 2018 for liver transplantation using the Nationwide Inpatient Sample. Patients <18 years old were excluded. Protein-energy malnutrition was identified by International Classification of Diseases Ninth and Tenth Revision codes. Multivariable regression was used to determine associations between protein-energy malnutrition and hospital outcomes, including hospital length of stay and hospital charges/costs.
RESULTS
Of 9856 hospitalizations, 2835 (29%) had protein-energy malnutrition. Patients with protein-energy malnutrition had greater comorbidity burden and in-hospital acuity (eg, dialysis, sepsis, vasopressors, or mechanical ventilation). The adjusted median difference of protein-energy malnutrition vs no protein-energy malnutrition for length of stay was 6.4 days (95% CI, 5.6-7.1; P < 0.001), for hospital charges was $108,063 (95% CI, $93,172-$122,953; P < 0.001), and for hospital costs was $23,636 (95% CI, $20,390-$26,882; P < 0.001).
CONCLUSION
Among patients undergoing liver transplantation, protein-energy malnutrition was associated with increased length of stay and hospital charges/costs. The additional cost of protein-energy malnutrition to liver transplantation programs was $23,636 per protein-energy malnutrition hospitalization. Our data justify the development of and investment in personnel and programs dedicated to reversing-or even preventing-protein-energy malnutrition in patients awaiting liver transplantation.

Observational Study
This study was intended to evaluate the pathological outcome of cardiopulmonary bypass whilst considering socio-demographic variables and surgical technique on early postoperative results following coronary artery bypass graft (CABG) surgery in patients at a tertiary level hospital in Bangladesh. This observational study evaluated a total of 880 patients with ischemic heart disease in Bangabandhu Sheikh Mujib Medical University, Bangladesh from 2011 to 2019 who were undergoing an isolated CABG surgery. In this current study, the population divided into two groups- Group A: Off-pump CABG (n=440) and Group B: On-pump CABG (n=440). The mean age of the patients was 55.25±5.0 years in off-pump and 50.75±5.2 years in the on-pump group. Risk factors, including smoking, hypertension, and hyperlipidemia, were predominant in both study groups. Total operative time was notably higher in the on-pump CABG group. However, grafting time was more in the off-pump CABG procedures. Postoperative neurological deficits were higher amongst the on-pump CABG population. The mean time of mechanical ventilation, intensive care unit (ICU) stay, total hospital stay, and mortality was notably higher in the on-pump CABG group. Moreover, the number of mortalities in on-pump CABG patients was primarily due to the low output syndrome, failure of weaning from cardiopulmonary bypass (CPB) and sudden cardiac arrest. Off-pump CABG is now more acceptable due to its potentiality to avoid CPB induced complications, aortic cannulation, and cross-clamping. Cardiac arrest in on-pump CABG induces global ischemia and reperfusion injury to the cardiac muscle. Besides, the Off-pump CABG provides a conspicuous survival advantage compared to the on-pump CABG, in association with a notable reduction in postoperative morbidity and mortality.

Reactive oxygen species in skeletal muscle injury, fatigue, regeneration and ageing: In memory of John Faulkner The role of zinc and matrix metalloproteinases in myofibrillar protein degradation in critical illness myopathy.
Due to an unexpected activation of different zinc (Zn) transporters in a recent prospective clinical study, we have revisited the role of Zn homeostasis and the activation of matrix metalloproteinases (MMPs) in skeletal muscle exposed to the intensive care unit (ICU) condition (immobilization and mechanical ventilation). ICU patients exposed to 12 days ICU condition were followed longitudinally with six repeated muscle biopsies while they showed a progressive preferential myosin loss, i.e., the hallmark of Critical Illness Myopathy (CIM), in parallel with the activation of Zn-transporters. In this study, we have revisited the expression of Zn-transporters and the activation of MMPs in clinical as well as in experimental studies using an established ICU model. MMPs are a group Zn-dependent endopeptidases which do not only target and cleave extracellular proteins but also intracellular proteins including multiple sarcomeric proteins. MMP-9 is of specific interest since the hallmark of CIM, the preferential myosin loss, has also been reported in dilated cardiomyopathy and coupled to MMP-9 activation. Transcriptional activation of Zn-transporters was observed in both clinical and experimental studies as well as the activation of MMPs, in particular MMP-9, in various limb and respiratory muscles in response to long-term exposure to the ICU condition. The activation of Zn-transporters was paralleled by increased Zn levels in skeletal muscle which in turn showed a negative linear correlation with the preferential myosin loss associated with CIM, offering a potential intervention strategy. Thus, activation of Zn-transporters, increased intramuscular Zn levels, and activation of the Zn-dependent MMPs are forwarded as a probable mechanism involved in CIM pathophysiology. These effects were confirmed in different rat strains subjected to a model of CIM and exacerbated by old age. This is of specific interest since old age and muscle wasting are the two factors most strongly associated with ICU mortality.

The American Journal of Emergency... Jun 2024We aimed to investigate the prognostic factors of pediatric extracorporeal cardiopulmonary resuscitation (ECPR).
OBJECTIVE
We aimed to investigate the prognostic factors of pediatric extracorporeal cardiopulmonary resuscitation (ECPR).
METHODS
The retrospective study included a total of 77 pediatric cases (7 neonates and 70 children) who underwent ECPR after in-hospital and out-of-hospital cardiac arrest between July 2007 and December 2022. Primary endpoints were complications, while secondary endpoints included all-cause in-hospital mortality.
RESULTS
Among the 45 cases experiencing complications, 4 neonates and 41 children had multiple simultaneous complications, primarily neurological issues in 25 cases. Additionally, organ failure occurred in 11 cases, and immunodeficiency was present in two cases. Furthermore, 9 cases experienced bleeding events, and 13 cases showed thrombosis. Patients with complications had lower weight, shorter ECMO durations, and longer CPR durations. Non-survivors had longer CPR durations and shorter durations of ECMO, ICU stay, and mechanical ventilation compared to survivors. Complications were more prevalent in non-survivors, particularly organ failure and bleeding events.
CONCLUSION
Weight, CPR duration, and ECMO duration were associated with complications, suggesting areas for treatment optimization. The higher occurrence of complications in non-survivors underscores the importance of early detection and management to improve survival rates. Our findings suggest clinicians consider these factors in prognostic assessments to enhance the effectiveness of ECPR programs.

BACKGROUND
The presence of nucleated red blood cells (NRBCs) in the peripheral blood of critically ill patients is associated with poor outcome. Evidence regarding the predictive value of NRBCs in patients with SARS-CoV-2-induced acute respiratory distress syndrome (ARDS) remains elusive. The aim of this study was to evaluate the predictive validity of NRBCs in these patients.
METHODS
Daily NRBC values of adult patients with SARS-CoV-2-induced ARDS were assessed and their predictive validity for mortality was statistically evaluated. A cut-off level based on the patient's maximum NRBC value during ICU stay was calculated and further specified according to Youden's method. Based on this cut-off value, further analyses such as logistic regression models and survival were performed.
RESULTS
413 critically ill patients with SARS-CoV-2-induced ARDS were analyzed. Patients who did not survive had significantly higher NRBC values during their ICU stay compared to patients who survived (1090/µl [310; 3883] vs. 140/µl [20; 500]; p < 0.0001). Patients with severe ARDS (n = 374) had significantly higher NRBC values during ICU stay compared to patients with moderate ARDS (n = 38) (490/µl [120; 1890] vs. 30/µl [10; 476]; p < 0.0001). A cut-off level of NRBC ≥ 500/µl was found to best stratify risk and was associated with a longer duration of ICU stay (12 [8; 18] vs. 18 [13; 27] days; p < 0.0001) and longer duration of mechanical ventilation (10 [6; 16] vs. 17 [12; 26] days; p < 0.0001). Logistic regression analysis with multivariate adjustment showed NRBCs ≥ 500/µl to be an independent risk factor of mortality (odds ratio (OR) 4.72; 95% confidence interval (CI) 2.95-7.62, p < 0.0001). Patients with NRBC values below the threshold of 500/µl had a significant survival advantage over those above the threshold (median survival 32 [95% CI 8.7-43.3] vs. 21 days [95% CI 18.2-23.8], log-rank test, p < 0.05). Patients who once reached the NRBC threshold of ≥ 500/µl during their ICU stay had a significantly increased long-term mortality (median survival 489 days, log-rank test, p = 0.0029, hazard ratio (HR) 3.2, 95% CI 1.2-8.5).
CONCLUSIONS
NRBCs predict mortality in critically ill patients with SARS-CoV-2-induced ARDS with high prognostic power. Further studies are required to confirm the clinical impact of NRBCs to eventually enhance decision making.

BACKGROUND
Conflicting findings regarding the impact of High protein intake during the early phase in critically ill patients have been reported. Therefore, we aimed to assess the influence of higher early protein intake on the prognosis of critically ill patients.
METHODS
This randomized controlled trial involved 173 critically ill patients who stayed in the Intensive Care Unit/Emergency ICU (ICU/EICU) for at least 7 days. The Low group (n = 87) and High group (n = 86) received protein supplementation of 0.8 g/kg.d and 1.5 g/kg.d, respectively, within 1-3 days of enteral nutrition (EN) initiation, with both groups transitioning to 1.5 g/kg.d on the 4th day. The serum prealbumin (PA), blood urea nitrogen/creatinine, and rectus femoris muscle thickness and cross-sectional area of all patients was measured on the 1th, 3rd, 5th, 7th day, and the day of ICU/EICU discharge.
RESULTS
Patients in both Low and High groups showed no significant differences in age, APACHE II scores, or other demographic and baseline characteristics. There were also no significant differences in the primary outcome (28-day mortality rate) and secondary outcomes (incidence rate of refeeding syndrome and EN tolerance score) between the two groups. However, the Low group exhibited a significantly higher 28-day mortality rate (HR = 2.462, 95% CI: 1.021-5.936, P = 0.045) compared to High group, as determined by Cox proportional hazards models incorporating the time factor. The High group exhibited significantly shorter durations of mechanical ventilation and ICU stay compared to the Low group. Serum PA levels were higher, and rectus femoris muscle atrophy rates were lower in the High group. Furthermore, for septic patients, high protein intake significantly reduced the 28-day mortality rate despite a small sample size (n = 34).
CONCLUSIONS
Our study indicates that increasing early protein intake to 1.5 g/kg.d may be safe and help improve the nutritional status and prognosis of critically ill patients.

OBJECTIVE
To determine the association between initial delivery room (DR) ventilator (conventional mechanical ventilation [CMV] versus high frequency oscillatory ventilation [HFOV] and hospital outcomes for infants with severe congenital diaphragmatic hernia (CDH).
STUDY DESIGN
Quasi-experimental design before/after introducing a clinical protocol promoting HFOV. The primary outcome was first blood gas parameters. Secondary outcomes included serial blood gas assessments, ECMO, survival, duration of ventilation, and length of hospitalization.
RESULTS
First pH and CO were more favorable in the HFOV group (n = 75) than CMV group (n = 85), median (interquartile range (IQR)) pH 7.18 (7.03, 7.24) vs. 7.05 (6.93, 7.17), adjusted p-value < 0.001; median CO 62.0 (46.0, 82.0) vs 85.9 (59.0, 103.0), adjusted p-value < 0.001. ECMO, survival, duration of ventilation, and length of hospitalization did not differ between groups in adjusted analysis.
CONCLUSION
Among infants with severe CDH, initial DR HFOV was associated with improved early gas exchange with no adverse differences in hospital outcomes.

BACKGROUND
Percutaneous dilatational tracheostomy (PDT) is the preferred method for managing critically ill patients requiring prolonged mechanical ventilation. We aimed to compare the safety of PDT performed by intensivists versus surgeons.
METHODS
This retrospective, single center, cohort study included all the patients who underwent PDT from 2014 to 2023. Propensity score matching was performed to adjust the imbalances of covariates between the groups. The primary outcome was the occurrence of early complications after PDT. Secondary outcomes were the development of late complications of PDT and mortality directly related to tracheostomy.
RESULTS
1685 consecutive patients with critical illness were included in the analysis. Of these, 1396 (82.8%) PDTs were performed by surgeons and 289 (17.2%) by intensivists with background residency training in internal medicine. Early complications were reported in 80 (5.7%) of the patients in the surgeon group and in 13 (4.5%) patients in the intensivist group (p = 0.40). Minor hemorrhage was the most common early complication. Secondary outcomes were comparable in both groups. In a propensity score-matched cohort, the findings remained consistent.
CONCLUSIONS
This study suggests that PDT can be performed by intensivists, as well as surgeons, with the same safety profile. Our findings underscore the importance of incorporating PDT into the intensive care unit (ICU) training syllabus, ensuring the procedure is readily accessible with reliance on the expertise of ICU staff.
