Introduction: Early risk stratification of critically ill patients is essential for optimizing intensive care unit (ICU) resource allocation and treatment decisions. Urinary liver-type fatty acid-binding protein (L-FABP) is a simple, noninvasive biomarker that may provide real-time information on organ dysfunction. However, its prognostic utility in patients admitted to the ICU from the emergency department remains unclear.
Aim of the study: The aim of this study was to evaluate the prognostic value of L-FABP levels measured shortly after ICU admission in predicting 28-day mortality among patients admitted from the emergency department.
Methods: This single-center retrospective observational study included patients admitted to the ICU between December 2020 and August 2022. Urinary L-FABP concentrations were measured at ICU admission (T0) and 3 hours later (T3). The primary outcome was 28-day in-hospital mortality. Prognostic performance was assessed using receiver operating characteristic curves and Cox proportional hazards models with inverse probability of treatment weighting. Results were compared with Acute Physiology and Chronic Health Evaluation (APACHE) II, Sequential Organ Failure Assessment (SOFA) scores, and lactate levels.
Results: Data of 118 patients were included in the final analysis. Urinary L-FABP levels at T3 showed the highest AUC for predicting 28-day mortality (area under the curve [AUC] = 0.873), compared with APACHE II (AUC = 0.801), SOFA (AUC = 0.753), and the lactate level (AUC = 0.734). An elevated L-FABP (T3) level was independently associated with increased mortality (hazard ratio [HR] = 8.60, 95% confidence interval [CI]: 1.02–72.64, P = 0.047). The T3/T0 ratio showed only modest predictive value (AUC = 0.623).
Conclusions: Urinary L-FABP levels measured 3 hours after ICU admission were an independent predictor of short-term mortality. The marker’s simplicity and bedside applicability suggest its potential utility not only in ICUs but also in emergency departments and triage decision-making.

Aim of the study: Short peripheral cannula (SPC)-related phlebitis occurs in 7.5% of critically ill patients, and mechanical irritation from cannula materials is a risk factor. Softer polyurethane cannulas reportedly reduce phlebitis, but the incidence of phlebitis may vary depending on the type of polyurethane. Differences in cannula stiffness may also affect the incidence of phlebitis; however, this relationship is not well understood. This study analyzed intensive care unit (ICU) patient data to compare the incidence of phlebitis across different cannula products, focusing on polyurethane.
Material and Methods: This is a post-hoc analysis of the AMOR-VENUS study that involved 23 ICUs in Japan. We included patients aged ≥ 18 years, who were admitted to the ICU with SPCs. The primary outcome was phlebitis, evaluated using hazard ratios (HRs) and 95% confidence intervals (CIs). Based on the market share and differences in synthesis, polyurethanes were categorized into PEU-Vialon® (BD, USA), SuperCath® (Medikit, Japan), and other polyurethanes; non-polyurethane materials were also analyzed. Multivariable marginal Cox regression analysis was performed using other polyurethanes as a reference.
Results: In total, 1,355 patients and 3,429 SPCs were evaluated. Among polyurethane cannulas, 1,087 (33.5%) were PEU-Vialon®, 702 (21.6%) were SuperCath®, and 276 (8.5%) were other polyurethanes. Among non-polyurethane cannulas, 1,292 (39.8%) were ethylene tetrafluoroethylene (ETFE) cannulas, and 72 (2.2%) used other materials. The highest incidence of phlebitis was observed with SuperCath® (13.1%). Multivariate analysis revealed an HR of 1.45 (95% CI 0.75-2.8, p = 0.21) for PEU-Vialon®, 2.60 (95% CI 1.35-5.00, p < 0.01) for SuperCath®, 2.29 (95% CI 1.19-4.42, p = 0.01) for ETFE, and 2.2 (95% CI 0.46-10.59, p = 0.32) for others.
Conclusions: The incidence of phlebitis varied among polyurethane cannulas. Further research is warranted to determine the causes of these differences.

DOI: 10.2478/jccm-2026-0013

Background: Acute kidney injury (AKI) is a common and serious complication in critically ill patients with non-kidney organ dysfunction. Early prediction of AKI is crucial for timely intervention and improved outcomes. This study aimed to identify readily available non-renal predictors of AKI and to develop an exploratory prediction model in a specific cohort of critically ill patients with COVID-19-related septic shock requiring mechanical ventilation.
Materials and methods: This was a single-center, observational, retrospective cohort study conducted in the respiratory ICU of Hospital H+ Querétaro between April and December 2020. The study included 42 mechanically ventilated patients with septic shock secondary to SARS-CoV-2 infection and non-kidney organ dysfunction. AKI was defined using the KDIGO criteria. Trend analysis, bivariate and multivariate linear regression, were used to identify predictors of AKI and severe AKI.
Results: AKI occurred in 23 (54.8%) patients, with 6 (14.3%) developing severe AKI. Trend analysis revealed differences in norepinephrine dose, hemoglobin, and lactate trends between groups. A simplified logistic regression model, validated internally with bootstrapping to prevent overfitting, identified a protective trend associated with higher hemoglobin levels on admission. Quantitative analysis of a forecasting model for daily renal function showed moderate predictive accuracy.
Conclusions: This study identified several readily available non-kidney organ dysfunction variables that can predict AKI and its severity in critically ill patients with COVID-19-related septic shock. These findings may help in the early identification of at-risk patients and facilitate timely interventions to potentially improve outcomes. Further validation in larger and more diverse populations is warranted.

DOI: 10.2478/jccm-2026-0011

Background: Managing sedation in critically ill COVID-19 patients is challenging due to high sedative requirements and organ dysfunction that alters drug metabolism. Inhaled sevoflurane offers a lung-eliminated alternative that may mitigate drug accumulation.
Methods: This single-center, retrospective cohort study analyzed 43 mechanically ventilated COVID-19 patients (March–November 2020). Patients received inhaled sevoflurane adjunctive to IV sedation (n=30) or IV sedation alone (n=13). The primary outcome was the cumulative dose of IV sedatives over 7 days. Secondary outcomes included time to extubation and antipsychotic use.
Results: There was no significant difference in the cumulative dose of IV sedatives between groups. However, the sevoflurane group had a significantly longer median duration of mechanical ventilation (206 [IQR 144-356] vs 144 [IQR 115-156] hours, p=0.005) and a higher requirement for antipsychotic medication (66.6% vs 15.3%, OR 18.6, p=0.011). Daily doses of propofol were lower in the sevoflurane group on specific days, but overall burden was unchanged.
Conclusions: In this cohort, adjunctive inhaled sevoflurane did not significantly reduce the cumulative burden of IV sedatives and was associated with delayed extubation and increased antipsychotic use. While sevoflurane is a feasible alternative, these findings suggest caution regarding weaning and delirium management in COVID-19 patients.

Objective: To analyze the frequency and types of postoperative complications and risk factors for in-hospital mortality.
Methods: This retrospective longitudinal study included adult patients who underwent surgical procedures and were admitted to the intensive care unit of a university hospital between March and July 2022. Study variables included sociodemographic, clinical, and epidemiological data; postoperative complications and hospital outcomes. The significance level was set at 5%.
Results: We analyzed 202 patients, with a median age of 67 years (IQR 55–74) and a predominance of males (62.4%). Inhospital mortality was 26.2%. Postoperative complications occurred in 84.7% of patients, with cardiovascular (53.4%), infectious (49.5%), and gastrointestinal (48.5%) complications being the most frequent. Early postoperative feeding was initiated in 34.2% of cases, and a delay was associated with a higher risk of complications. Nausea and vomiting prophylaxis were administered to most patients—intraoperatively in 61.9% and postoperatively in 96%. In logistic regression analysis, female sex, urgent surgery, and higher SAPS 3 scores were identified as independent risk factors for death.
Conclusions: Postoperative complications were highly prevalent and associated with an increased risk of death. Intraoperative nausea and vomiting prophylaxis and early postoperative feeding were associated with a lower frequency of complications. Identified risk factors for mortality included female sex, higher SAPS 3 scores, and urgent surgeries.

Background: Sarcopenia, defined by a loss of skeletal muscle mass and function, has been identified as a prevalent condition associated with poor clinical outcome among critically ill patients. This study aims to evaluate the impact of pre-existing sarcopenia on outcomes in critically ill patients with acute respiratory failure (ARF) due to COVID-19.
Material and Methods: A retrospective study was carried out on COVID-19 patients admitted to intensive care. Pre-existing sarcopenia was assessed using early CT scans. Clinical outcomes, including duration of high-flow oxygenation (HFO), mechanical ventilation (MV), length of hospital stay (LOS) and ICU mortality, were evaluated according to sarcopenia status.
Results: Among the studied population, we found a high prevalence (75 patients, 50%) of pre-existing sarcopenia, predominantly in older male patients. Pre-existing sarcopenia significantly impacted HFO duration (6.8 (+/-4.4) vs. 5 (+/-2.9) days; p=0.005) but did not significantly affect MV requirement (21 (28%) vs. 23 (37.3%); p=185), MV duration (7 vs. 10 days; p=0.233), ICU mortality (12 (16%) vs. 10 (13.3 %); p=0.644) or hospital LOS (27 vs. 25 days; p=0.509). No differences in outcomes were observed between sarcopenic and non-sarcopenic obese patients.
Conclusions: Pre-existing sarcopenia in critically ill COVID-19 patients is associated with longer HFO duration but not with other adverse outcomes. Further research is needed to elucidate the mechanisms and broader impact of sarcopenia on septic critically ill patient outcomes.

Background: Acute kidney injury (AKI) is a disease that affects millions of people globally making it a major public health concern. It is defined as an abrupt decrease in kidney function that occurs within ours affecting both the structure and functionality of the kidneys.
The outcome of AKI and the determinants in Nigeria are largely unknown. This study aimed to describe the determining factors of the outcome of AKI patients admitted into the ICU of three tertiary health institutions in Northeast Nigeria.
Methods: The study is a prospective multicentered observational study of the patients admitted into the ICU in three tertiary health institutions from January 2022 to December 2023. KDIGO criteria was used to define AKI. The outcome of the study was to determine survivors among the patients admitted into the ICU with AKI or developed AKI while in ICU and also the determinants of mortality. A chi-square test was done to determine the association between the dependent variable (patient outcome) and the independent variables. To determine the predictors of patient outcomes, a regression analysis was done. The sociodemographic data of the patients admitted during these periods were studied in addition to Acute Physiology and Chronic Health Evaluation (APACHE) II, Kidney Disease: Improving Global Outcomes (KDIGO), Average length of stay in the ICU, Admitting/referring ward (Obstetrics, Gynae, Medical, Surgical or Emergency unit), Ability to afford care (out of pocket payment, social welfare or through Health insurance Scheme, Co-morbidity (presence or absence of comorbidity), Interventions done while in ICU (use of vasopressors and inotropes, mechanical ventilation (MV) support and renal replacement therapy (RRT) and outcome (discharge to the wards or mortality).
Results: Of 1494 patient records screened, 464 met the inclusion criteria. The overall incidence of AKI was 57%. About 53% were females, the mean age was 42.2 years, and 81% of the patients had a normal BMI (18.5 – 24.9). About 40% of the patients had APACHE II scores ≥ 29%. More than three-quarters (79.5%) of the patients paid for their health care expenditure out-of-pocket. Most patients (72%) were from the Medical and Gynae/Ward. Mortality was highest (54.2%) among patients who were brought into the ICU from the Medical ward. Most patients admitted were KDIGO I (44.3%) followed by KDIGO II (35.1%). Among the patients, 61.2% present with one or more comorbidity. Mortality was higher (50%) among those with comorbidity compared to 13.6% among those without comorbidity. Mortality was lowest among patients who stayed in the ICU between 8-14 days compared to those who stayed > 2 weeks. Most of the patients (72%) were from the Medical and Gynae/Ward. Mortality was highest (54.2%) among patients who were brought into the ICU from the Medical ward followed by those brought in from the Obstetric and Gynecological ward (20.4%). An association was found between the intervention received in the ICU and the outcome, which was found to be statistically significant (p < 0.001). A regression analysis was done to determine the predictors of patients’ outcomes admitted in the ICU. The results showed that APACHE II score greater than 10 (p-value < 0.001), presence of comorbidities (p = 0.031) and intervention which included a combination of Vasopressors, mechanical ventilation and RRT (p < 0.01) are the predictors of patients’ outcome. The regression model is valid (X2 = 469.894, df = 24, p < 0.001) and it fits the sample as shown by the Hosmer and Lemeshow test (X2 = 7.749, p = 0.45, df = 8,). It also shows that the predictors account for 92% of patients’ outcomes (Nagelkerke R2 = 0.92).
Conclusions: Our study revealed that the presence of comorbidity, high APACHE II score, and the need for interventional supports including both mechanical ventilatory and ionotropic, were found to be strong mortality predictors in patients with AKI.

Introduction: Professionals in Intensive Care Units face death, shifting their role from therapists to caregivers in end-of-life management. The nursing attitude and response to death has been shown to affect the quality of palliative care and end-of-life services that are interrelated services. Aim of the study: The aim of this research was to evaluate the professional attitude of nurses towards the care of the families of critically ill patients in the ICU, leading to the emergence of specific attitudes, relating them to their demographic and professional characteristics, with the aim of drawing conclusions for the improvement of quality in end-of-life care.
Material and Methods: The sample of the study was 81 nurses from a large tertiary hospital. Participants completed the “Nurse Activities for Communicating with Families” (NACF) questionnaire. The questions are about ways in which nurses can help the patient’s family during the patient’s stay in the ICU.
Results: The results revealed that the nurses took actions related to the information and psychological support of the patient’s family. On the contrary, they did not focus on the spiritual / religious needs of the patient and the needs of the family based on their cultural background.
Conclusions: The professional treatment of staff is characterized by compassion and empathy, but it is necessary to train them on important issues related to diversity, including the religious, spiritual values ​​and beliefs of patients and their relatives.

The novel coronavirus disease, 2019 (COVID – 19) evolved as an unprecedented pandemic. The severe acute respiratory syndrome-corona virus-2 (SARS-CoV-2) infection has been associated with significantly deranged coagulation parameters and increased incidence of thrombotic events. Deranged coagulation parameters, such as D-dimers and fibrin degradation products, can indicate a poor prognosis, and their measurement will help stratify the patients according to the disease severity, need of intensive care unit admission, and prediction of the clinical course. Gaps in understanding the natural history of the disease cause difficulties in tailoring therapies and optimizing the management of patients. Lack of specific treatment further complicates this situation. While thrombotic events can cause significant morbidity and mortality in patients, a focused approach to the prevention and treatment of venous thromboembolism (VTE) can, to a great extent, decrease the disease burden caused by thrombotic diseases. Pharmacological prophylactic anticoagulants and mechanical therapies such as pneumatic compression devices can help prevent venous thromboembolism and other thrombotic events. Thrombotic events due to COVID-19, their prevention and management, are the focus of this paper, with the prospect of providing insights into this relatively unexplored area.

Introduction: Pediatric delirium is a significant problem when encounterd in an intensive care unit (ICU). The pathophysiology of pediatric delirium is complex and the etiology is typically multifactorial. Even though various risk factors associated with pediatric delirium in a pediatric ICU have been identified, there is still a paucity of literature associated with the condition, especially in extremely critically ill children, sedated and mechanically ventilated. Aim of the study: To identify factors associated with delirium in mechanically ventilated children in an ICU.
Material and Methods: This is a single-center study conducted at a tertiary care pediatric ICU. Patients admitted to the pediatric ICU requiring sedation and mechanical ventilation for >48 hours were included. Cornell Assessment of Pediatric Delirium scale was used to screen patients with delirium. Baseline demographic and clinical factors as well as daily and cumulative doses of medications were compared between patients with and without delirium. Firth’s penalized maximum likelihood logistic regression was used on a priori set of variables to examine the association of potential factors with delirium. Two regression models were created to assess the effect of daily medication doses (Model 1) as well as cumulative medication doses (Model 2) of opioids and benzodiazepines.
Results: 95 patient visits met the inclusion criteria. 19 patients (20%) were diagnosed with delirium. Older patients (>12 years) had higher odds of developing delirium. Every 1mg/kg/day increase in daily doses of opioids was associated with an increased risk of delirium (OR=1.977, p=0.017). Likewise, 1 mg/kg increase in the cumulative opioid dose was associated with a higher odds of developing delirium (OR=1.035, p=0.022). Duration of mechanical ventilation was associated with the development of delirium in Model 1 (p=0.007).
Conclusions: Age, daily and cumulative opioid dosage and the duration of mechanical ventilation are associated with the development of delirium in mechanically ventilated children.
