Choking is a significant health concern associated with substantial morbidity and mortality. Despite ongoing efforts, an optimal solution remains elusive. We propose that this may stem from an overemphasis on mechanical obstruction as the primary cause. Notably, a foreign body does not always completely occlude the airway. For instance, Saccomanno et al. reported that fish bones were implicated in 67% of choking incidents [1], suggesting that defensive airway reflexes may play a critical role beyond mere mechanical obstruction.

Introduction: Understanding the association between risk factors and clinical outcomes of COVID-19 can lead to identifying suitable management strategies for reducing the mortality rate among maternal COVID-19 patients in the ICU.
Aim of the Study: This study aims to investigate the clinical outcomes and risk factors associated with pregnant and postpartum women diagnosed with COVID-19 and admitted to the intensive care unit (ICU) between May 2020 and September 2021.
Materials and Methods: This retrospective cohort study was conducted at the Universitas Indonesia Hospital. Secondary data was collected from the medical records to include all pregnant and postpartum women diagnosed with confirmed COVID-19 admitted to the hospital during the research period.
Results: The study included 113 patients and found that admission to the ICU, age, and gestational age significantly influenced clinical outcomes, with a mortality rate of 42.11% among ICU-admitted patients. Pre-existing comorbidities such as type-2 diabetes mellitus, congestive heart failure, and coronary artery disease were associated with ICU admission. Having at least one comorbidity was found to increase the mortality rate by six-fold.
Conclusions: The study emphasizes the importance of monitoring and evaluating maternal and fetal complications during COVID-19 infection, highlighting the need for multidisciplinary management involving intensivists, obstetricians, anesthesiologists, and infectious disease specialists. The findings underscore the significance of baseline health status in treatment planning and the potential for evidence-based interventions to improve maternal outcomes and pregnancy preservation. Further research is warranted to validate these results and enhance understanding of the underlying pathophysiology.

DOI: 10.2478/jccm-2025-0007

Objective: Systematically examine the literature describing midodrine to treat shock and to summarize current administration and dosing strategies.
Data sources: Structured literature search conducted in MEDLINE (PubMed) from inception through May 10, 2023.
Study Selection and Data Extraction: Abstracts and full texts were assessed for inclusion by two blinded, independent reviewers. English-language publications describing use of midodrine in adult patients with shock were included. Data were extracted by two blinded, independent abstractors using a standardized extraction tool. Quality assessments were completed by paired reviewers using JBI methodology.
Data Synthesis: Fifteen of 698 (2%) screened manuscripts were included with 1,714 patients with a variety of shock types. Seven studies (47%) were retrospective, two (13%) prospective observational, and six (40%) randomized controlled studies. Midodrine was initiated to facilitate intravenous vasopressor (IVP) weaning in most (11, 73%) studies; only two (13%) reported IVP weaning protocol use. Starting doses were 10 mg every 8 hours (4, 27%) or three times a day (3, 20%), 20 mg every 8 hours (2, 13%); six studies (40%) did not report initial midodrine dosing. A midodrine titration protocol was reported in 6 (40%) studies. Thirteen (87%) studies evaluated for bradycardia, identified in 6 (46%) studies among 204 patients; only one (0.5%) patient required midodrine discontinuation. Three (20%) studies reported on hypertension with an incidence of 7-11%. Four (27%) studies assessed for ischemia; 5/1128 (0.4%) patients experienced mesenteric ischemia requiring midodrine discontinuation.
Relevance to Patient care and Clinical Practice: This review explores the pragmatic details involved in initiating, titrating, and weaning midodrine for the bedside clinician and identifies rates of adverse events and complications.
Conclusions: Published literature describing midodrine use for shock is heterogeneous and comprised primarily of low or very low quality data. Future controlled trials addressing the shortcomings identified in this systematic review are warranted.

Introduction: The survival benefits of treatment at high-volume hospitals (HVHs) are well-documented for several critical pediatric conditions. However, their impact on pediatric sepsis, a leading cause of mortality among children, remains understudied.
Aim of the study: To investigate the association between hospital case volume and mortality rates in pediatric sepsis.
Material and Methods: We conducted a retrospective cohort study using data from the Diagnosis Procedure Combination database. The study included patients who met the following criteria: 1) aged 28 days to 17 years; 2) discharged from the hospital between April 2014 and March 2018; 3) had a sepsis diagnosis coded under the International Classification of Diseases, 10th revision; 4) underwent blood cultures on hospital admission day (day 0) or day 1; 5) received antimicrobial agents on day 0 or 1; and 6) required at least one organ support measure (e.g., mechanical ventilation or vasopressors) on day 0 or 1. Hospitals were categorized by case volume during the study period, with HVHs defined as those in the highest quartile and low-volume hospitals (LVHs) as those in the remaining quartiles. In-hospital mortality rates between HVH and LVH groups were compared using mixed-effects logistic regression analysis with propensity score (PS) matching.
Results: A total of 934 pediatric patients were included in the study, with an overall in-hospital mortality rate of 16.1%. Of them, 234 were treated at 5 HVHs (≥26 patients in 4 years), and 700 at 234 LVHs (<26 patients in 4 years). Upon PS matching, patients treated at HVHs demonstrated significantly lower odds of in-hospital mortality compared with those treated at LVHs (odds ratio, 0.42; 95% confidence interval, 0.22–0.80; P = 0.008).
Conclusions: In pediatric patients with sepsis, treatment at HVHs was associated with lower odds of in-hospital mortality.

Introduction: The extent of in vivo damage to the alveolar-capillary membrane in patients with primary lung injury remains unclear. In cases of ARDS related to COVID-19 and Influenza type A, the complexity of the damage increases further, as viral pneumonia cannot currently be treated with a causal approach.
Aims of the study: Our primary goal is to enhance the understanding of Acute Respiratory Distress Syndrome (ARDS) by demonstrating damage to the alveocapillary membrane in critically ill patients with COVID-19 and influenza type A. We will achieve this by measuring the levels of proteins and albumin in bronchoalveolar fluid (BAL) and serum. Our secondary objective is to assess patient outcomes related to elevated protein and albumin levels in both BAL and blood serum, which will deepen our understanding of this complex condition.
Materials and methods: Bronchoalveolar lavage (BAL) fluid and serum samples were meticulously collected from a total of 64 patients, categorized into three distinct groups: 30 patients diagnosed with COVID-19-related acute respiratory distress syndrome (ARDS), 14 patients with influenza type A (H1N1 strain), also experiencing ARDS, and a control group consisting of 20 patients who were preoperatively prepared for elective surgical procedures without any diagnosed lung disease. The careful selection and categorization of patients ensure the robustness of our study. BAL samples were taken within the first 24 hours following the commencement of invasive mechanical ventilation in the intensive care unit, alongside measurements of serum albumin levels. In the control group, BAL and serum samples were collected after the induction of general endotracheal anaesthesia.
Results: Patients in the COVID-19 group are significantly older than those in the Influenza type A (H1N1) group, with median ages of 72.5 years and 62 years, respectively (p < 0.01, Mann-Whitney U test). Furthermore, serum albumin levels (measured in g/L) revealed significant differences across all three groups in the overall sample, yielding a p-value of less than 0.01 according to ANOVA. In terms of treatment outcomes, serum albumin levels also exhibited a significant correlation, with a p-value of 0.03 (Mann-Whitney U test). A reduction in serum albumin levels (below 35 g/L), combined with elevated protein levels in bronchoalveolar lavage (BAL), serves as a predictor of poor outcomes in patients with acute respiratory distress syndrome (ARDS), as indicated by a p-value of less than 0.01 (ANOVA).
Conclusions: Our findings indicate that protein and albumin levels in bronchoalveolar lavage (BAL) fluid are elevated in severe acute respiratory distress syndrome (ARDS) cases. This suggests that BAL can effectively evaluate protein levels and fractions, which could significantly assist in assessing damage to the alveolocapillary membrane. Additionally, the increased albumin levels in BAL, often accompanied by a decrease in serum albumin levels, may serve as a valuable indicator of compromised integrity of the alveolar-capillary membrane in ARDS, with potential implications for patient care.

Introduction: Acute respiratory distress syndrome (ARDS) is characterized by progressive lung inflammation which leads to increased dead space that can cause hypercapnia and can increase the risk of patient morbidity and mortality. In an attempt to improve ARDS patient outcomes provision of protective lung ventilation has been shown to improve patient mortality but increases the incidence of hypercapnia. Therefore, the role of carbon dioxide in ARDS remains contradicted by conflicted evidence. This study aims to examine this conflicting relationship between hypercapnia and mortality in mechanically ventilated COVID-19 ARDS patients.
Methods: We conducted a retrospective cohort study. The data was collected from the medical records of the patients admitted with COVID-19 ARDS in Sindh Infectious Disease Hospital &Research Centre (SIDH & RC) from August 2020 to August 2022 and who received mechanical ventilation for more than 48 hours. The patients were grouped into severe and no severe hypercapnia groups based on their arterial blood carbon dioxide levels (PaCO2). To understand the effect of hypercapnia on mortality we performed multivariable logistic regression, and inverse probability-weighted regression to adjust for time-varying confounders.
Results: We included 288 patients to detect at least 3% of the effect on mortality. Our analysis revealed an association of severe hypercapnia with severe lung injury, low PaO2/FiO2, high dead space, and poor compliance. In univariate analysis severe hypercapnia showed higher mortality: OR=3.50, 95% CI [1.46-8.43]. However, after, adjusting for disease severity hypercapnia is not found to be associated with mortality: OR=1.08, 95% CI [0.32 -3.64]. The sensitive analysis with weighted regression also shows no significant effect on mortality: OR=1.04, 95% CI [0.95-1.14].
Conclusion: This study showed that hypercapnia is not associated with mortality in COVID-19 ARDS patients.

The pathophysiology of sepsis is orchestrated by a delicate and dynamic interaction between pro-inflammatory and anti-inflammatory responses. Essential factors influencing this process include interleukin-7 (IL-7), the programmed cell death protein 1/programmed death ligand 1 (PD-1/PD-L1) axis, and cellular apoptosis. These elements shape the immune response in sepsis, influencing its progression and outcomes. IL-7 is an important cytokine maintaining lymphocyte function and survival. At the same time, the PD-1/PD-L1 axis acts as a modulatory checkpoint suppressing immune activation to prevent overreaction but can exacerbate immunosuppression during sepsis. Cellular apoptosis impairs the host’s ability to mount an effective defence, especially against secondary infections.
Despite extensive research, the precise mechanisms through which sepsis results in organ dysfunction and immune dysregulation remain incompletely understood. The global burden of sepsis emphasizes the urgent need for innovative approaches, paving the way for personalized, immune-based therapies.
This review aims to delve into and synthesize the current knowledge regarding cellular apoptosis, the regulatory role of the PD-1/PD-L1 axis, and the critical functions of IL-7 in sepsis, with a focus on their underlying mechanisms, clinical relevance, and potential as targets for future immunomodulatory treatments.

DOI: 10.2478/jccm-2025-0002

Objective: This is a pilot study to determine the feasibility of a multicentre stepped wedge cluster randomized trial of implementing the 2013 World Society of the Intraabdominal Compartment Syndrome (WSACS) guidelines as an intervention to treat intraabdominal hypertension (IAH) and abdominal compartment syndrome (ACS) in critically ill patients.
Design: Single-centre before-and-after trial, with an observation / baseline period of 3 months followed by a 9-month intervention period.
Setting: A 35 bed medical-surgical-trauma intensive care unit in a tertiary level, Canadian hospital.
Patients: Recruitment from consecutively admitted adult intensive care unit patients.
Intervention: In the intervention period, treatment teams were prompted to implement WSACS interventions in all patients diagnosed with IAH.
Measurements and Main Results: 129 patients were recruited, 59 during the observation period and 70 during the intervention period. Only 17.0% and 12.9%, respectively, met diagnostic criteria for IAH. Many recruited patients did not have intraabdominal pressures measured regularly per study protocol. There was no difference in ICU mortality for patients in either cohort or between those with and without IAH.
Conclusions: The incidence of IAH in our patient population has decreased significantly since 2015. This is likely due to a significant change in routine care of critically ill patients, especially with respect to judicious goal-directed fluid resuscitation. Patient recruitment and protocol adherence in this study were low, exacerbated by other staffing and logistical pressures during the study period. We conclude that a larger multicentre trial is unlikely to yield evidence of a detectable treatment effect.

DOI: 10.2478/jccm-2025-0001

Introduction: In traumatic brain injury (TBI), direct information can be obtained about cerebral blood flow, brain tissue oxygenation and cerebral perfusion pressure values. More importantly, an idea about the changes in these measurements can be obtained with multidimensional monitoring and widely used monitoring methods.
Aim of the study: We aimed to evaluate the monitoring of critically ill children who were followed up in our pediatric intensive care unit (PICU) due to TBI.
Material and Method: Twenty-eight patients with head trauma who were followed up in our tertiary PICU between 2018 and 2020 were included in the study. Cerebral tissue oxygenation, optic nerve sheath diameter (ONSD), Glasgow coma score (GCS) and Glasgow Outcome Score (GOSE) values were obtained from retrospective file records and examined.
Results: Male gender was 71.4% (n=20). When we classified TBI according to GCS, 50% (n=14) had moderate TBI and 50% had severe TBI. On the first day in the poor prognosis group, ONSD and nICP were found to be higher than in the good prognosis group (for ONSD, p=0.01; and for nICP, p=0.004). On the second day of hospitalization, the ONSD and nICP were significantly higher in the poor prognosis group than in the good prognosis group (for ONSD p=0.002; and for nICP p= 0.001). Cerebral tissue oxygenation values measured on the first and second days decreased significantly on the second day in both the good and poor prognosis groups (p=0.03, 0.006). In the good prognosis group, a statistically significant decrease was found in ONSD and nICP measurements taken on the 2nd day compared to the measurements taken at the time of hospitalization (for ONSD p=0.004; for nICP p<0.001).
Conclusion: The aim of multidimensional follow-up in traumatic brain injury is to protect the brain from both primary and secondary damage; for this reason, it should be followed closely with multimonitoring methods that are possibly multidisciplinary.

Introduction: Brain abscess is a serious condition in children, leading to rapid deterioration, and permanent neurological damage associated with significant morbidity and mortality. Current management protocols for brain abscesses focus on intravenous antibiotics and surgical excision and drainage.
Case Presentation: A 12-year-old adolescent male who had headache and photophobia and was diagnosed with multiple brain abscesses and was refractory to conventional medical and neurosurgical intervention. A single dose of 10 mg vancomycin was administered through endo-ventricular drain , resulting in resolution of abscesses and alleviation of symptoms.
Conclusion: We describe the first instance of intraventricular vancomycin use in the pediatric age group for the treatment of multiple brain abscesses. Given the variability in dosing reported in the literature, our case report warrants further studies to standardize dosage for this rare intervention.
