Urine high-sensitive troponin I in children cannot offer an applicable alternative to serum.

Introduction: In children, congenital heart defects represent the primary cause of increased serum troponin I. The elimination process of cardiac troponin I from the bloodstream and the factors influencing this process remain unknown. The objective of this study was to explore the role of troponin I as an indicator of cardiac damage in children both in serum and urine, a concept previously investigated in adults. Methods: Our prospective study involved 70 children under 24 months of age. The first group underwent ventricular septal defect repair, while the second group involved children who had undergone partial cavopulmonary anastomosis. For these groups, urine and serum troponin I were assessed on four occasions. The third group, consisting of healthy children, underwent a single measurement of urine troponin I. Results: Serum troponin I values exhibited an expected elevation in the early postoperative period, followed by a return to lower levels. Significantly higher concentrations of serum troponin I were observed in the first group of children (p < 0.05). A positive correlation was found between troponin I in the first three measurements and cardiopulmonary bypass and aortic cross-clamping time. There was no discernible increase in urine troponin I directly related to myocardial damage; troponin I couldn't be detected in most urine samples. Discussion: The inability to detect troponin I in urine remains unexplained. Potential explanatory factors may include the isoelectric point of troponin I, elevated urinary concentrations of salts and urea, variations in urine acidity (different pH levels), and a relatively low protein concentration in urine.

Starting Pediatric VAD Program: Transforming Challenges into Opportunities; A Case Series of a Single Center.

BACKGROUND: The prevalence of heart failure is constantly increasing in both children and adults. End-stage heart failure in children unresponsive to medical therapy has limited treatment options. Surgical options include heart transplantation or implantation of durable ventricular assist devices (VADs). To start the VAD program, it was necessary to train core team members, invite experienced proctors and adjust the organizational approach. METHODS: We present our first seven pediatric patients who underwent a VAD implantation with primary indication end-stage dilated cardiomyopathy. RESULTS: The median age on implant was four and a half years and the median duration of VAD support was 39 days with long term survival achieved in three patients. The causes of death were multiorgan failure, thromboembolic events, sepsis, and low cardiac output syndrome. Ischemic stroke was the reason for successful neurointervention during VAD support in two patients. CONCLUSIONS: To establish a VAD program, numerous specialties must be included with adequate training and learning for all team members.

Extracorporeal membrane oxygenation in children: An update of a single tertiary center 11-Year experience from Croatia.

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) is an important treatment option for organ support in respiratory insufficiency, cardiac failure, or as an advanced tool for cardiopulmonary resuscitation. Reports on pediatric ECMO use in our region are lacking. METHODS: This study is a retrospective review of all pediatric cases that underwent a veno-arterial (VA) or veno-venous (VV) ECMO protocol between November 2009 and August 2020 at the Department of Pediatrics, University Hospital Center Zagreb, Croatia. RESULTS: Fifty-two ECMO runs identified over the period; data were complete for 45 cases, of which 23 (51%) were female, and median age was 8 months. Thirty-eight (84%) patients were treated using the VA-and 7 (16%) using VV-ECMO. The overall survival rate was 51%. Circulatory failure was the most common indication for ECMO (N = 38, 84%), and in 17 patients ECMO was started after cardiopulmonary resuscitation (E-CPR). Among survivors, 74% had no or minor neurological sequelae. Variables associated with poor outcome were renal failure with renal replacement therapy (p < .001) and intracranial injury (p < .001). CONCLUSION: Overall survival rate in our cohort is comparable to the data published in the literature. The use of hemodialysis was shown to be associated with higher mortality. High rates of full neurological recovery among survivors are a strong case for further ECMO program development in our institution.

End-of-Life Decision-Making in Pediatric and Neonatal Intensive Care Units in Croatia-A Focus Group Study among Nurses and Physicians.

Background and Objectives: Working in pediatric and neonatal intensive care units (ICUs) can be challenging and differs from work in adult ICUs. This study investigated for the first time the perceptions, experiences and challenges that healthcare professionals face when dealing with end-of-life decisions in neonatal intensive care units (NICUs) and pediatric intensive care units (PICUs) in Croatia. Materials and Methods: This qualitative study with focus groups was conducted among physicians and nurses working in NICUs and PICUs in five healthcare institutions (three pediatric intensive care units (PICUs) and five neonatal intensive care units (NICUs)) at the tertiary level of healthcare in the Republic of Croatia, in Zagreb, Rijeka and Split. A total of 20 physicians and 21 nurses participated in eight focus groups. The questions concerned everyday practices in end-of-life decision-making and their connection with interpersonal relationships between physicians, nurses, patients and their families. The constant comparative analysis method was used in the analysis of the data. Results: The analysis revealed two main themes that were the same among the professional groups as well as in both NICU and PICU units. The theme "critical illness" consisted of the following subthemes: the child, the family, myself and other professionals. The theme "end-of-life procedures" consisted of the following subthemes: breaking point, decision-making, end-of-life procedures, "spill-over" and the four walls of the ICU. The perceptions and experiences of end-of-life issues among nurses and physicians working in NICUs and PICUs share multiple common characteristics. The high variability in end-of-life procedures applied and various difficulties experienced during shared decision-making processes were observed. Conclusions: There is a need for further research in order to develop clinical and professional guidelines that will inform end-of-life decision-making, including the specific perspectives of everyone involved, and the need to influence policymakers.

Attitudes about withholding or withdrawing life-prolonging treatment, euthanasia, assisted suicide, and physician assisted suicide: a cross-sectional survey among the general public in Croatia.

BACKGROUND: There has been no in-depth research of public attitudes on withholding or withdrawing life-prolonging treatment, euthanasia, assisted suicide and physician assisted suicide in Croatia. The aim of this study was to examine these attitudes and their correlation with sociodemographic characteristics, religion, political orientation, tolerance of personal choice, trust in physicians, health status, experiences with death and caring for the seriously ill, and attitudes towards death and dying. METHODS: A cross-sectional study was conducted on a three-stage random sample of adult citizens of the Republic of Croatia, stratified by regions, counties, and locations within those counties (N = 1203). In addition to descriptive statistics, ANOVA and Chi-square tests were used to determine differences, and factor analysis (component model, varimax rotation and GK dimensionality reduction criterion), correlation analysis (Bivariate correlation, Pearson's coefficient) and multiple regression analysis for data analysis. RESULTS: 38.1% of the respondents agree with granting the wishes of dying people experiencing extreme and unbearable suffering, and withholding life-prolonging treatment, and 37.8% agree with respecting the wishes of such people, and withdrawing life-prolonging treatment. 77% of respondents think that withholding and withdrawing procedures should be regulated by law because of the fear of abuse. Opinions about the practice and regulation of euthanasia are divided. Those who are younger and middle-aged, with higher levels of education, living in big cities, and who have a more liberal worldview are more open to euthanasia. Assisted suicide is not considered to be an acceptable practice, with only 18.6% of respondents agreeing with it. However, 40.1% think that physician assisted suicide should be legalised. 51.6% would support the dying person's autonomous decisions regarding end-of-life procedures. CONCLUSIONS: The study found low levels of acceptance of withholding or withdrawing life-prolonging treatment, euthanasia, assisted suicide and physician assisted suicide in Croatia. In addition, it found evidence that age, level of education, political orientation, and place of residence have an impact on people's views on euthanasia. There is a need for further research into attitudes on different end-of-life practices in Croatia.

Characteristics, Risk Factors and Predictors for Candidemia in the Pediatric Intensive Care Unit at the University Hospital Centre Zagreb in Croatia: A 9-Year Retrospective Study.

BACKGROUND: Candidemia is one of the leading causes of bloodstream infections in the pediatric intensive care unit (PICU). The aim of this study was to define characteristics and risk factors for candidemia in the PICU setting and propose a predictive model to identify the patients at risk. METHODS: This was a retrospective matched case-control study in the PICU during a 9-year period. Patients with candidemia were studied and matched with control patients without candidemia. Univariate analysis was performed for potential risk factors and multivariate analysis was conducted to determine the prediction score for candidemia. RESULTS: Forty-two cases of candidemia were matched with 84 control patients. Candida parapsilosis was the most common (71.4%) species. Risk factors independently associated with candidemia were: the use of >2 antibiotics in a maximum period of 4 weeks before the candidemia (odds ratio [OR]: 10.59; 95% confidence interval [CI]: 2.05-54.83), a previous bacterial infection in a maximum period of 4 weeks before the candidemia (OR: 5.56; 95% CI: 1.44-21.5) and the duration of PICU stay of >10 days (OR: 4.22; 95% CI: 1.02-17.41). The proposed predictive scoring system has a sensitivity of 95.24%, specificity of 76.12%, OR 64.0, 95% CI 14.2-288.6, the positive predictive value of 66.67% and the negative predictive value of 96.97%. CONCLUSIONS: Previously reported risk factors for candidemia have been confirmed and some new have been detected. The presented scoring system can help identify patients who would benefit from prophylactic antifungal therapy.

How health care professionals confront and solve ethical dilemmas - a tale of two countries: Slovenia and Croatia.

AIM: To assess the differences in the way how Slovenian and Croatian health care professionals (HCPs) confront ethical dilemmas and perceive the role of hospital ethics committees (HECs). METHODS: This cross-sectional, survey-based study involved HCPs from three Slovenian and five Croatian university medical centers (UMC). The final sample sizes were 308 (244 or 79.2% women) for Slovenia and 485 (398 or 82.1% women) for Croatia. RESULTS: Compared with Croatian physicians, Slovenian physicians reported a higher share of ethical dilemmas regarding waiting periods for diagnostics or treatment, suboptimal working conditions due to interpersonal relationships in the ward, and end-of-life treatment withdrawal, and a lower share regarding access to palliative care and patient information protection. Compared with Croatian nurses, Slovenian nurses reported a lower share of ethical dilemmas regarding the distribution of limited resources, recognizing the patient's best interests, and access to palliative care. Compared with Croatian other HCPs, Slovenian other HCPs reported a lower burden of ethical dilemmas regarding waiting periods for diagnostics or treatment, distribution of limited resources, and access to palliative care. When encountering an ethical dilemma, all HCPs in both countries would first consult their colleagues. Slovenian and Croatian HCPs recognized the importance of the HECs to a similar extent, but viewed their role differently. CONCLUSION: Croatian and Slovenian HCPs are confronted with different ethical dilemmas and perceive the role of HECs differently.

Rescue extracorporeal cardiopulmonary resuscitation in pediatric patients: a nine-year single-center experience in Zagreb, Croatia.

AIM: To investigate the risk factors and the outcomes of extracorporeal membrane oxygenation (ECMO) in pediatric patients treated at the University Hospital Center Zagreb, the largest center in Croatia providing pediatric ECMO. METHODS: This retrospective study enrolled all the pediatric patients who required E-CPR from 2011 to 2019. Demographic data, cardiac anatomy, ECMO indications, ECMO complications, and neurodevelopmental status at hospital discharge were analyzed. RESULTS: In the investigated period, E-CPR was used in 16 children, and the overall survival rate was 37.5%. Six patients were in the neonatal age group, 5 in the infant group, and 5 in the "older" group. There was no significant difference between the sexes. Four patients had an out-of-hospital arrest and 12 had an in-hospital arrest. Twelve out of 16 patients experienced renal failure and needed hemodialysis, with 4 out of 6 patients in the survivor group and 8 out of 10 in the non-survivor group. Survivors and non-survivors did not differ in E-CPR duration time, lactate levels before ECMO, time for lactate normalization, and pH levels before and after the start of ECMO. CONCLUSION: The similarity of our results to those obtained by other studies indicates that the ECMO program in our hospital should be maintained and improved.

Hernia Sac Presence Portends Better Survivability of Isolated Congenital Diaphragmatic Hernia with "Liver-Up".

Objective The objective of this study was to investigate the prognostic value of a hernia sac in isolated congenital diaphragmatic hernia (CDH) with intrathoracic liver herniation ("liver-up"). Study Design A retrospective study from the single tertiary center. Isolated "liver-up" CDH neonates referred to our institution between 2000 and 2015 were reviewed for the presence or absence of a hernia sac. Association between the presence of a hernia sac and survival was assessed. Results Over the study period, there were 29 isolated CDH patients with "liver-up" who were treated, 7 (24%) had a sac, and 22 (76%) did not. Demographics were similar between groups. However, disease acuity, assessed from lower Apgar scores (p = 0.044), lower probability of survival (p = 0.037), and lower admission oxygenation (p = 0.027), was higher in neonates without a sac. Hospital survival was significantly higher for those with sac compared with those without (7/7, 100 vs. 7/22, 32%, p = 0.002). Conclusion The presence of a hernia sac may be associated with better survival for isolated "liver-up" CDH. As the presence of sac can be prenatally detected, it may be a useful marker to aid perinatal decision making.

Epidemiology and Outcomes of Congenital Diaphragmatic Hernia in Croatia: A Population-Based Study.

BACKGROUND: Outcomes of neonates with congenital diaphragmatic hernia (CDH) are variable; reports are frequently limited to the experience of single tertiary care centres-a possible source of bias. Population-based studies decrease survivor bias and provide additional insight into this high-mortality condition. The objective of this study was to examine the incidence and outcomes of CDH in Croatia. METHODS: All cases of CDH in Croatia from 2001 through 2013 were ascertained from public health records. Overall and sex- and region-specific incidence rates were calculated, and characteristics associated with 1-year survival were assessed. RESULTS: We identified 145 cases of CDH during the study period, for an incidence of 2.67 per 10 000 total births. The incidence did not differ by calendar year (P = 0.38) or geographic region (P = 0.67). There was a slightly higher incidence among males (rate ratio, 1.37, 95% CI 0.99, 1.91). The 1-year survival rate was 33.1% for the entire cohort and 47.9% for liveborns who received any treatment at an intensive care unit. From multivariable analysis, survival was decreased in neonates with left CDH, liver up (odds ratio 0.1, 95% CI, 0.03, 0.4) and increased when treated in a centre with higher case volume (odds ratio 12.8, 95% CI, 2.2, 72.1). CONCLUSIONS: The incidence of CDH in Croatia is within the range of previous reports. Survival was substantially higher in neonates treated in a centre with higher case volume, which suggests that centralisation of medical care for CDH may be warranted in Croatia.

Biliary atresia: the Croatian experience 1992-2006.

The objective of this study was to determine the outcomes of Croatian children with biliary atresia. Health records of infants born in Croatia between January 1, 1992 and December 31, 2006 who were diagnosed with biliary atresia and treated at a single university center were reviewed. Survival rates were calculated with the Kaplan-Meier method. Twenty-nine patients with biliary atresia were identified. Incidence was one in 23,600 live births (95% confidence interval 1/17,400-1/27,200). The median age at Kasai operation was 66 days (range 22-192). Median follow-up was 2.65 years (range 0.2-14.3). Overall survival rates for the patients who underwent Kasai portoenterostomy, including those six (20%) who subsequently underwent liver transplantation, were 75.6%. Five and 10-year native liver survival rates were 51.7% and 38.8%, respectively (median survival time was 7.88 years). Survival rate curves in two groups of patients according to the biliary atresia phenotype (fetal or perinatal form) were divergent. Survival was 87.7% in perinatal form and 43.8% in fetal form (Breslow chi-square 8.082, p < 0.01). Overall survival rates of patients with biliary atresia in Croatia compared unfavorably with current international standards; this could be improved with earlier referral for liver transplantation. Results of Kasai operation (native liver survival rates) compared favorably with results reported elsewhere.

Recombinant activated factor VII controls chemotherapy-related hemorrhage in patients with solid intra-abdominal tumors: a report of three pediatric cases.

Recombinant activated factor VII (rFVIIa; NovoSeven, Novo Nordisk, Bagsvaerd, Denmark) is used predominantly for the treatment of bleeding in patients with hemophilia and inhibitors, and in patients with traumatic injury. There are also literature reports of its use in chemotherapy-related bleeding in leukemia patients and intra- or postoperative bleeding in patients with solid tumors. We describe three pediatric patients where rFVIIa was successfully used to manage bleeding following the failure of conventional hemostatic treatments during chemotherapy for intra-abdominal tumors (hepatoblastoma, rhabdomyosarcoma and non-classified malignant sarcoma). Recombinant FVIIa proved effective and maintained hemostasis in two of three cases, with no evidence for toxic or adverse events in any of the treated patients.

The life-threatening hemodialysis catheter heparin lock caused bleeding in a child after peritoneal catheter removal.

Hemodialysis catheter patency is regularly maintained by high-concentration heparin filling, according to manufacturer's recommendation. Surprisingly, there are only few reports on serious bleeding complications in children on dialysis. A case of serious, life-threatening hemorrhage in a child after tunneled peritoneal catheter removal because of hemodialysis catheter heparin lock flushing is described. Discussion of the literature data is presented. Further investigations are needed to develop the guidelines for pediatric dialysis catheter care, including the optimal concentration for heparin lock as the possible heparin alternatives, but until that moment, previously suggested guidelines to prevent hemorrhagic complications in dialyzed children should be emphasized.

Fatal infant nasal seawater spray instillation.

UNLABELLED: The use of seawater nasal spray is considered safe and sold as a non-prescription medicine. However, it is well known that nasal manipulations can provoke vagal reaction leading to acute life-threatening events. A case of fatal seawater nasal spray application in an infant is presented. CONCLUSION: We do not consider the use of seawater nasal spray to be absolutely safe, especially among infants with disordered autonomic function.
