Objective: We evaluated how pre-treatment clinical and echocardiographic findings influence treatment decisions for patent ductus arteriosus (PDA) in preterm neonates. Study Design: Preterm neonates weighing < 1500 g and diagnosed with PDA were enrolled. They were categorized into conservative, medical, and surgical groups based on treatment. Results: A total of 242 preterm neonates (120 boys and 122 girls) participated, with a mean gestational age of 27.9 ± 2.2 weeks and a birth weight of 1034.3 ± 239.3 g. Multivariate logistic regression revealed that oliguria (p < 0.001), inotropic drug use (p = 0.049), low PDA flow velocity (p = 0.039), and left atrial enlargement (p = 0.002) were significantly associated with medical or surgical treatment decisions. Additionally, a low base deficit prior to medical therapy was associated with the decision to proceed with surgical intervention after medical treatment failure (p = 0.006). Conclusions: Oliguria, inotropic drug use, low PDA flow velocity, and left atrial enlargement were significantly associated with aggressive treatment decisions in preterm neonates with PDA. Furthermore, a low base deficit influenced the need for surgery following medical therapy failure. Our findings suggest that comprehensive monitoring of both clinical and echocardiographic factors may support treatment decision-making in PDA management in preterm neonates. Full article

Background/Objectives: Acute hypoxemic respiratory failure is a significant condition commonly seen in intensive care units (ICUs), yet specific prognostic markers related to it for mortality remain largely unstudied. This study aimed to identify parameters that influence mortality in ICU patients diagnosed with type 1 respiratory failure. Methods: A retrospective cohort study was conducted at a tertiary care hospital, including patients admitted to the ICU between March 2016 and March 2020. The study included patients with type 1 respiratory failure, while exclusion criteria were prior long-term respiratory support, type 2 respiratory failure, and early mortality (<24 h). Data on demographics, comorbidities, support requirements, laboratory values, and ICU scoring systems (APACHE II, SOFA, SAPS II, NUTRIC) were collected. Binomial regression analysis was used to determine independent predictors of 30-day mortality. Results: Out of 657 patients screened, 253 met the inclusion criteria (mean age 70.6 ± 15.6 years; 65.6% male). Non-survivors (n = 131) had significantly higher CCI scores; greater vasopressor requirements; and elevated SAPS II, APACHE, SOFA, and NUTRIC scores. Laboratory findings indicated higher inflammatory markers and lower nutritional markers (albumin and prealbumin, respectively) among non-survivors. In the regression model, SAPS II (OR: 13.38, p = 0.003), the need for inotropic support (OR: 1.11, p = 0.048), NUTRIC score (OR: 2.75, p = 0.014), and serum albumin (inverse; OR: 1.52, p = 0.001) were independently associated with mortality. The model had an AUC of 0.926 and classified 83.2% of cases correctly. When combined, SAPS II and mNUTRIC had more AUC compared to either standalone scoring. Conclusions: SAPS II, vasopressor requirements, mNUTRIC score, and low serum albumin are independent predictors of 30-day mortality in patients with acute hypoxemic respiratory failure. These findings support the integration of nutritional assessment, a combination of available scoring systems and comprehensive scoring into routine ICU evaluations for this patient group.

Objective: The aim of this study was to describe the presenting characteristics and outcomes of neonates with respiratory failure referred for extracorporeal membrane oxygenation (ECMO) support, compare those who received ECMO support (ECMO group) to those who did not (non-ECMO group), and evaluate the predictive variables requiring ECMO support. Methods: All neonates (<15 days) with respiratory failure (without congenital diaphragmatic hernia or congenital heart disease) referred to our regional ECMO center from 2014 to 2023 were included in this retrospective study. Patient demographics, birth history, and clinical and outcome variables were analyzed. Oxygenation indices and vasoactive–inotropic scores obtained at PICU arrival and four hours after arrival were compared between the two groups using ROC analysis, with ECMO initiation as an outcome variable. Youden’s index was used for optimal threshold values. Chi-square, Mann–Whitney U, and binary logistic regression were used for comparative analyses. Results: Out of the 147 neonates, 96 (65%) required ECMO support. The two groups significantly differed in the prevalence of pulmonary hypertension (pHTN; systemic or suprasystemic pulmonary pressures), lactate level, and oxygenation indices. Mortality was not different between the two groups. Presence of oxygen saturation index (OSI) ≥ 10 had a sensitivity 96.8% in predicting the need for ECMO support. On regression analysis, OSI and pHTN were independent predictors of ECMO support. Conclusions: Oxygenation indices and echo findings predict the need for ECMO support in neonatal hypoxemic respiratory failure. These findings help non-ECMO centers make appropriate and timely transfers of neonates with respiratory failure to ECMO centers. Full article

Background: The management of multiple organ failure in the vulnerable cohort of cardiac surgery patients with cardiogenic shock remains a significant challenge, often impairing patient survival. A multimodal approach at targeting organ dysfunction seems to be a promising strategy, encompassing both hemodynamic support as well as differentiated organ replacement therapy. Materials and Methods: In our retrospective study we examined the impact of the ADVOS (advanced organ support) system on overall outcomes and survival in an all-comers group of 22 cardiac surgery patients with postoperative cardiogenic shock and multiple organ failure. Aims: The objective of the study was to assess the feasibility and potential benefits of ADVOS treatment in this patient population. Results: The standard care management in combination with ADVOS therapy corrected acid–base balance (pH 7.33 vs. 7.44, p = 0.001; base excess −3.2 vs. 2.4 mmol/L, p < 0.001). This contributed to restoring hemodynamic balance after two consecutive ADVOS treatments (vasoactive inotropic score (VIS) 59 vs. 21, p = 0.007, noradrenaline 0.470 vs. 0.180 µg/kg/min, p = 0.009). Conclusions: Our findings indicate that ADVOS treatment is both feasible and safe, with a substantial proportion of patients demonstrating improvements in organ function and overall outcomes.

Staphylococcus aureus infections are an important cause of morbidity and mortality among patients in intensive care units (ICUs), particularly those with multiple comorbidities and critical conditions. Methicillin-resistant S. aureus (MRSA) and methicillin-sensitive S. aureus (MSSA) strains differ in resistance, clinical behavior, and prognoses, making it important to understand their effects on clinical outcomes. Comparing clinical outcomes of MRSA and MSSA infections is important. This retrospective cohort study analyzed ICU patients with confirmed S. aureus infections at a quaternary care hospital. Demographic, clinical, and comorbidity data were collected. Poisson regression was used to analyze 7-day mortality and identify adjusted risk factors. Seven-day mortality was higher in patients with MSSA than MRSA infections, with an adjusted relative risk for MRSA of 0.380 (95% confidence interval: 0.15–0.95; p = 0.039). Independent risk factors for mortality included lack of an infectious disease consultation, vascular comorbidities, such as peripheral vascular disease and cerebrovascular events, chronic kidney disease, and inotropic support requirement. Patients with MRSA infections required significantly longer ventilatory support (mean 43.5 days vs. 13 days for MSSA; p = 0.019). Staphylococcus aureus infections in ICU patients were associated with poor outcomes, particularly in patients without infectious disease consultation and those with vascular comorbidities. Mortality differences between MRSA and MSSA highlight the importance of appropriate empiric therapy and standardized protocols incorporating infectious disease consultation to improve outcomes in critically ill patients.

Background and Clinical Significance: The incidence of persistent ductus arteriosus (PDA) in preterm infants is the highest and depends on their birth weight (BW) and respiratory condition after birth. Previously, after the unsuccessful drug treatment, surgical ligation was the primary treatment option. However, according to clinical studies, the Amplatzer Piccolo Occluder was approved for PDA closure for patients ≥700 g. In our country, percutaneous PDA embolization has not been performed yet. Case Presentation: We present three premature infants with hemodynamically significant patent ductus arteriosus (hsPDA) in whom percutaneous occlusion was performed using the Amplatzer Piccolo Occluder (APO). The average gestational week (GW) was 27 ± 1, while body weight was 1030 ± 60 g. All patients had respiratory deterioration, with dilatation of the left heart chambers, and renal failure. The second developed a severe form of broncho-pulmonary dysplasia. Transthoracic echocardiography (TTE) examinations revealed a hemodynamically significant PDA (LA/Ao 1.8–2.2) and medical closure was unsuccessfully carried out. Due to the hemodynamically significant PDA maintenance in all neonates, transvenous PDA closure was performed using the APO (APO 9-PDAP-04-02-L, 9-PDAP-04-04-L, 9-PDAP-05-054L, respectively). The entire devices, with both retention discs, are implanted within the duct. TTE pointed out adequate device position without descending aorta, left pulmonary artery obstruction, residual shunt, and reverse remodelling of the left ventricle and left atrium. The first newborn was weaned from mechanical ventilation three days after the procedure and discharged three weeks after. The second patient was extubated 2 weeks after the procedure, and even the severe BPD, X-ray showed improvement. The third patient’s renal failure completely resolved, weaned from inotropic drug support and mechanical ventilation. Conclusions: Due to a significantly lower complication rate than surgical ligation, we will strive to make percutaneous PDA occlusion a new standard for treatment in newborns, especially preterm newborns, in our country.

Background: Antegrade root cardioplegia remains the most popular strategy for myocardial protection during coronary artery bypass graft (CABG) performed with cardiopulmonary bypass (CPB) and aortic cross clamp. In patients with depressed left ventricular function, however, especially if associated with severe multiple coronary stenosis, increased pharmacological and/or mechanical support in the early post-CPB period is often required to support left ventricular recovery. In this study, we analyzed the results of a myocardial protection strategy that includes selective infusion of cardioplegia through each venous graft followed by warm reperfusion distal to each coronary anastomosis until complete removal of the aortic clamp (total antegrade cardioplegia infusion and warm reperfusion = TAWR) to improve early postoperative recovery in patients with depressed left ventricular function undergoing multi-vessel CABG. Methods: Out of 97 patients undergoing CABG using the TAWR strategy for myocardial protection, 32 patients presented with depressed left ventricle function (EF < 40%) and multi-vessel coronary diseases requiring ≥2 vein grafts and were enrolled as Group A. Combined primary outcomes and postoperative early and late left ventricle recovery (including spontaneous rhythm recovery, inotropic support and postoperative troponin release) were analyzed and compared with those of 32 matched patients operated on using standard antegrade root cardioplegia and limited warm reperfusion through LIMA graft (SAWR) enrolled as Group B. Results: Two patient died in hospital (in-hospital mortality 3.1%) with no statistical differences between the two groups. In Group A 27 patients (90%) had spontaneous recovery of idiopathic rhythm compared to 17 (53%) in group B (p = 0.001). Early inotropic support was required in nine patients (28%) of group A and seventeen patients (53%) of group B (p = 0.041). Furthermore, in eight patients (25%) of group A and seventeen (53%) of group B (p = 0.039) inotropic support was continued for >48 h. Conclusions: The TAWR strategy seems to significantly improve early postoperative cardiac recovery in patients with left ventricle depression undergoing multi-vessel CABG, when compared with SAWR strategy and could therefore be considered the strategy of choice in this subset of patients.

Background/Objectives: Acute heart failure (AHF) is a common cause of emergency department (ED) referral. Different guidelines aim to optimise this condition, but the evidence is poor for most indications regarding AHF. In this paper, we aim to (i) identify the five most interesting topics in AHF management, (ii) compare guidelines, and (iii) give the reader the best advice on how to manage AHF in each topic. Methods: The working group (WG) identified ten critical topics in AHF management using a Delphi method and submitted them to ITEMS, a national group of ED physicians that ranked them. The WG selected the five highest-ranked topics and performed a critical reappraisal of guidelines. Lastly, the WG prepared the answers for ED physicians according to the guidelines and comparisons of studies. Results: The WG identified five topics for ED patients with AHF: (i) what is the optimal oxygen and ventilatory support, (ii) what is the optimal dose and administration modality of diuretics, (iii) what is the role of inotropes and vasopressors, (iv) what therapeutic strategies are suggested for diuretic refractoriness, and (v) what is the diagnostic role of lung ultrasound. For each topic, the WG identified, summarised, and compared the indications provided by each guideline, generating advice for ED management of AHF after a critical literature reappraisal. Conclusions: We highlighted the differences among guidelines dealing with AHF and developed the five best recommendations to assist ED physicians in determining the optimal approach for the ED management of AHF and to suggest future research directions.

Background: Stress-induced cardiomyopathy (SI-CM) is a transient left ventricular dysfunction triggered by emotional or physical stress, often resolving with supportive care. However, severe cases may progress to cardiogenic shock (CS), requiring mechanical circulatory support (MCS). High-profile transvalvular pumps (HPTP), a form of percutaneous ventricular assist device, offer promising hemodynamic support in acute heart failure. This report explores HPTP use in SI-CM-related CS through two complex clinical cases. Case Summary: Two elderly female patients presented with severe CS secondary to apical-variant SI-CM. Case 1 involved a 67-year-old woman with sepsis, colonic perforation, and recurrent SI-CM, leading to profound low-output shock despite multiple vasopressors and inotropes. HPTP was implanted via the axillary artery, allowing for surgical management of intra-abdominal pathology and eventual cardiac recovery. Case 2 featured a 77-year-old woman with multifocal pneumonia, severe mitral regurgitation, and complete heart block. HPTP implantation stabilized her hemodynamics, facilitated extubation, and led to full recovery of ventricular function. Results: Both patients showed marked improvement in cardiac output and systemic perfusion following HPTP insertion. Echocardiograms post-device removal revealed normalization of left ventricular ejection fraction (55–64%). Hemodynamic data confirmed reduced pulmonary capillary wedge pressure and systemic vascular resistance. Conclusion: These cases highlight the potential of HPTP in managing SI-CM-related CS, especially when traditional therapies are inadequate or contraindicated. HPTP can rapidly restore hemodynamic stability and support myocardial recovery. While current data are limited, these observations underscore the need for broader investigation into the role of HPTP in this setting. Full article

Background: Prolonged use of inotropes drugs in the early postoperative period is one of the most common complications occurring in patients undergoing heart valve surgery. Patients requiring prolonged support via inotropes drugs are significantly more likely to experience serious postoperative complications such as acute kidney injury, cardiogenic shock, multiple organ dysfunction syndrome, and death. This study assessed the usefulness of selected perioperative parameters in predicting prolonged postoperative use of inotropic drugs and cardiogenic shock and/or death in a group of patients requiring prolonged supply of inotropes drugs. Methods: This prospective study was conducted on a group of 607 patients undergoing heart valve surgery. The primary endpoint in-hospital follow-up was prolonged postoperative use of inotropes drugs. The secondary composite endpoint was cardiogenic shock requiring mechanical circulatory support (MCS) and/or death from any cause in patients with prolonged postoperative use of inotropes drugs. Results: A total of 210 patients required inotropes drugs for more than 48 h. Age (p = 0.03), preoperative atrial fibrillation (p < 0.001), preoperative NT-proBNP level (p < 0.001), Troponin T measured one day after surgery (TnT II) (p < 0.001), and the need for urgent postoperative rethoracotomy (p < 0.001) remained independent predictors of primary endpoint. Preoperative hemoglobin level (p = 0.001) and TnT II (p < 0.001) were independent predictors of death and cardiogenic shock requiring MCS. Conclusions: Patients with elevated preoperative NT-proBNP values, as well as with increasing postoperative troponin T levels, are at risk of prolonged postoperative use of inotropes drugs, a complication which is associated with a significant risk of developing further adverse consequences, such as cardiogenic shock and death.

Objectives: The pulmonary artery pulsatility index (PAPI) is a novel hemodynamic parameter that reflects right ventricular (RV) function. PAPI was shown to be useful in predicting outcomes following left ventricular assist device (LVAD) implantation, acute RV infarction, and in patients with chronic RV failure. The standard method to estimate PAPI is during right heart catheterization (RHC); however, echocardiography-based PAPI was also shown to be accurate. In the current study, we evaluated the ability of echocardiography-based PAPI to predict outcomes of patients with acute pulmonary embolism (PE). Methods: A total of 177 patients (mean age 67 ± 15, 54.1% male) with acute PE were included in the study. PAPI was calculated based on measurements from standard transthoracic echocardiography. Results: 27% of patients needed oxygen support, 5.6% were on mechanical ventilation, and 7.3% were on inotropic support. The 30-day mortality rate in the whole cohort was 8.3%. Lower PAPI measurements were associated with increased 30-day mortality (p < 0.05), a higher rate of RV failure (p < 0.001), and the need for inotropic support (p < 0.05). There was no association between PAPI and the need for oxygen support (p = 0.59), mechanical ventilation (0.06), or length of stay (LOS) (p = 0.414). PAPI was superior to tricuspid annular plane systolic excursion (TAPSE) in predicting mortality and RV failure. Conclusions: Echocardiography-derived PAPI is feasible and superior over TAPSE in predicting RV failure and mortality among patients with acute PE. Full article

Background and Clinical Significance: Takotsubo cardiomyopathy (TCM), an acute stress-induced left ventricular dysfunction, stems from catecholaminergic surges leading to transient myocyte stunning, calcium overload, and microvascular dysregulation. Although most cases resolve spontaneously, roughly 10% deteriorate into fulminant cardiogenic shock, warranting mechanical circulatory support (MCS). Impella^® provides direct transvalvular LV unloading but carries elevated risks of hemolysis, vascular compromise, and thrombogenicity. Conversely, the intra-aortic balloon pump (IABP) enhances diastolic coronary perfusion and marginally reduces afterload via counterpulsation, albeit with less potent LV decompression. Optimal MCS selection in TCM-associated shock therefore hinges on balancing hemodynamic benefits against procedural morbidity. Case Presentation: A 72-year-old female with coronary artery disease, paroxysmal atrial fibrillation (status post–left atrial appendage occlusion), and stage 3 chronic kidney disease presented with anterior ST-segment elevations (V2–V4) and troponin I >1000 ng/L, progressing rapidly to cardiogenic shock and respiratory failure. Coronary angiography revealed mild luminal irregularities, while echocardiography demonstrated severely reduced ejection fraction (5–10%) with characteristic apical ballooning. Refractory elevations in pulmonary capillary wedge pressure, despite escalating inotropes and vasopressors, prompted IABP insertion for partial LV offloading. Over one week, her ejection fraction improved to 35%, facilitating weaning from pressor support, extubation, and discharge on guideline-directed medical therapy. Conclusions: In TCM complicated by shock, meticulous MCS selection is paramount. Although Impella confers more robust unloading, heightened device-related complications may be unjustified in a largely reversible disease. IABP can sufficiently stabilize hemodynamics, enable myocardial recovery, and mitigate morbidity, underscoring the importance of individualized decision-making in TCM-related shock. Importantly, no trial has shown that MCS confers a proven long-term mortality benefit beyond initial hemodynamic rescue. Full article

Background: Sodium regulation is critical in extremely low-birth-weight (ELBW, <1000 g) infants. In a recent systematic review, a sodium pattern over postnatal age and its variables (care factors, fluid regimens, and maturational factors) has been summarized. However, this systematic review also illustrated the shortages and limitations of reported cohorts, and the need to report on additional datasets. This study therefore aims to describe the postnatal sodium patterns and their variables in a cohort of ELBW neonates in the first 10 days of postnatal life. Methods: Data on 1704 serum sodium observations in the first 10 days of life from 211 ELBW infants hospitalized in a single neonatal intensive care unit were available to explore associations between serum sodium and perinatal variables. Multivariate linear models with sodium as a response variable and postnatal day as a factor were hereby applied. Baseline and treatment characteristics were included as variables, applying an unstructured covariance matrix to account for the longitudinal data. Results: Gestational age, birth weight, and length showed variable correlations with serum sodium concentrations over postnatal age. Interestingly, the analysis of sodium patterns in this ELBW cohort also revealed significant associations between prenatal betamethasone use, delivery mode, ibuprofen, or the use of inotropes and the postnatal serum sodium concentrations patterns. Multivariate analyses confirmed that gestational age and birth weight independently impacted sodium concentration patterns, and that ibuprofen use remained a significant variable after adjusting for these variables. Conclusions: Gestational age and birth weight complexities emphasize the need for nuanced understanding and standardized methodologies. Sodium patterns in the current ELBW cohort provide support for previously published sodium reference patterns in this population. New variables associated with sodium levels include ibuprofen administration and the use of inotropic agents. Full article

Background and Objectives: The coronavirus disease 2019 pandemic presented unprecedented challenges in balancing infection control measures with the timely management of ST-segment elevation myocardial infarction (STEMI), a time-sensitive condition. This study investigates the pandemic’s effects on STEMI management times and outcomes at a high-volume medical center in Taiwan. Materials and Methods: A retrospective analysis of 1309 STEMI patients was conducted at Chang Gung Memorial Hospital between 2017 and 2022. Patients were divided into pre-pandemic and pandemic groups. Measurement outcomes include in-hospital mortality rate, management times (e.g., door-to-balloon time), the rates of intra-aortic balloon pump (IABP) and/or veno-arterial extracorporeal membrane oxygenation (VA-ECMO) usage, mechanical ventilation, inotropic support, and the length of intensive care unit (ICU) and hospital stay. Kaplan–Meier survival analysis and statistical comparisons were performed to assess temporal trends and prognostic outcomes. Results: No significant difference in in-hospital mortality was observed between pre-pandemic (5.85%) and pandemic (7.03%) groups (p = 0.45). The pandemic group experienced longer management times, including door-to-cath arrival (p = 0.0335) and door-to-balloon time (p = 0.014), although all times remained below the 90 min threshold. Quality improvements during the first outbreak allowed the institution to handle higher case volumes during subsequent waves without further delays. Ninety-day survival analysis showed no significant disparity between groups (p = 0.3655). Conclusions: Pandemic-related delays in STEMI management were effectively mitigated through workflow optimization, preventing significant increases in mortality rates. This study highlights the adaptability of healthcare systems in responding to crises while maintaining quality care for time-sensitive emergencies. Future multicenter studies could provide broader insights into global STEMI management strategies under pandemic conditions. Full article

Ethephon (2-chloroethylphosphonic acid) is a generally used plant growth regulator, but the data on its toxic effects, especially in humans, are very limited. This study was conducted to describe the clinical characteristics, management, and outcomes of patients exposed to products containing ethephon. We performed an 8-year retrospective study using data from the Ramathibodi Poison Center database (2013–2020), which included 252 patients. Most patients were male, with a median age of 32 years. Almost all patients were exposed through ingestion, mainly in unintentional circumstances. The clinical presentations included local effects, gastrointestinal (GI), neurological, and respiratory symptoms. Some patients required hospital admission; specifically, seven patients received inotropic drugs, and six were intubated with ventilator support. Most patients had either no or only minor clinical effects. However, six patients experienced moderate/severe effects, and two patients died. Age, intentional exposure, and the presence of initial neurological symptoms could prognosticate moderate to fatal outcomes. In conclusion, exposure to ethephon predominantly resulted in no or minor effects, and GI symptoms were the most common clinical manifestation. The cholinergic toxic syndrome was not frequently observed. The mortality rate was very low. Patients presenting with factors associated with worse outcomes should be monitored closely for clinical deterioration and appropriately managed. Full article
