Evaluation of nutritional status in pediatric intensive care unit patients: the results of a multicenter, prospective study in Turkey.

Introduction: Malnutrition is defined as a pathological condition arising from deficient or imbalanced intake of nutritional elements. Factors such as increasing metabolic demands during the disease course in the hospitalized patients and inadequate calorie intake increase the risk of malnutrition. The aim of the present study is to evaluate nutritional status of patients admitted to pediatric intensive care units (PICU) in Turkey, examine the effect of nutrition on the treatment process and draw attention to the need for regulating nutritional support of patients while continuing existing therapies. Material and Method: In this prospective multicenter study, the data was collected over a period of one month from PICUs participating in the PICU Nutrition Study Group in Turkey. Anthropometric data of the patients, calorie intake, 90-day mortality, need for mechanical ventilation, length of hospital stay and length of stay in intensive care unit were recorded and the relationship between these parameters was examined. Results: Of the 614 patients included in the study, malnutrition was detected in 45.4% of the patients. Enteral feeding was initiated in 40.6% (n = 249) of the patients at day one upon admission to the intensive care unit. In the first 48 h, 86.82% (n = 533) of the patients achieved the target calorie intake, and 81.65% (n = 307) of the 376 patients remaining in the intensive care unit achieved the target calorie intake at the end of one week. The risk of mortality decreased with increasing upper mid-arm circumference and triceps skin fold thickness Z-score (OR = 0.871/0.894; p = 0.027/0.024). The risk of mortality was 2.723 times higher in patients who did not achieve the target calorie intake at first 48 h (p = 0.006) and the risk was 3.829 times higher in patients who did not achieve the target calorie intake at the end of one week (p = 0.001). The risk of mortality decreased with increasing triceps skin fold thickness Z-score (OR = 0.894; p = 0.024). Conclusion: Timely and appropriate nutritional support in critically ill patients favorably affects the clinical course. The results of the present study suggest that mortality rate is higher in patients who fail to achieve the target calorie intake at first 48 h and day seven of admission to the intensive care unit. The risk of mortality decreases with increasing triceps skin fold thickness Z-score.

Mortality risk factors among critically ill children with MIS-C in PICUs: a multicenter study.

BACKGROUND: This study evaluated of clinical characteristics, outcomes, and mortality risk factors of a severe multisystem inflammatory syndrome in children admitted to a the pediatric intensive care unit. METHODS: A retrospective multicenter cohort study was conducted between March 2020 and April 2021 at 41 PICUs in Turkey. The study population comprised 322 children diagnosed with multisystem inflammatory syndrome. RESULTS: The organ systems most commonly involved were the cardiovascular and hematological systems. Intravenous immunoglobulin was used in 294 (91.3%) patients and corticosteroids in 266 (82.6%). Seventy-five (23.3%) children received therapeutic plasma exchange treatment. Patients with a longer duration of the PICU stay had more frequent respiratory, hematological, or renal involvement, and also had higher D-dimer, CK-MB, and procalcitonin levels. A total of 16 patients died, with mortality higher in patients with renal, respiratory, or neurological involvement, with severe cardiac impairment or shock. The non-surviving group also had higher leukocyte counts, lactate and ferritin levels, and a need for mechanical ventilation. CONCLUSIONS: In cases of MIS-C, high levels of D-dimer and CK-MB are associated with a longer duration of PICU stay. Non-survival correlates with elevated leukocyte counts and lactate and ferritin levels. We were unable to show any positive effect of therapeutic plasma exchange therapy on mortality. IMPACT: MIS-C is a life-threatening condition. Patients need to be followed up in the intensive care unit. Early detection of factors associated with mortality can improve outcomes. Determining the factors associated with mortality and length of stay will help clinicians in patient management. High D-dimer and CK-MB levels were associated with longer PICU stay, and higher leukocyte counts, ferritin and lactate levels, and mechanical ventilation were associated with mortality in MIS-C patients. We were unable to show any positive effect of therapeutic plasma exchange therapy on mortality.

Evaluation of viral respiratory pathogens in children aged under five hospitalized with lower respiratory tract infections.

Objective: Lower respiratory tract infections (LRTIs) are responsible for significant morbidity and mortality in children. Viral pathogens are responsible for 50-70% of LRTIs. The real-time multiplex polymerase chain reaction (RT-MPCR) tests allow the simultaneous detection of several different viruses along with some bacterial pathogens and give faster and more reliable results than viral culture. We aimed to describe the disease etiology and the clinical, laboratory, and radiological characteristics of children aged under 5 years who were hospitalized in a tertiary care medical center with LRTIs assayed using an RT-MPCR respiratory pathogen panel, and evaluate the effects of the detection of etiology on treatment and outcome. Methods: This retrospective study was conducted in the tertiary medical health center. The study group comprised all pediatric cases aged under five who were hospitalized due to LRTIs in the pediatric wards and pediatric intensive care unit (ICU) and undergone RT-MPCR analyses between January 2019 and February 2020. RT-MPCR analyses of samples from nasopharyngeal swabs were consecutively evaluated. Results: A total of 65 samples were collected from aged under 5 years who were hospitalized with LRTIs and screened for respiratory viruses. Specimens were collected from pediatric ICU (18.5%) and pediatric wards (81.5%). The overall positive rate was 89.2% (58/65). Forty of the patients (61.5%) were positive for a single pathogen, 15 (23.6%) for two, and three (4.6%) for three pathogens. The most common virus was respiratory syncytial virus (RSV) (32.3%), followed by human rhinovirus (HRV) (30.8%). In HRV-positive patients, eosinophil count was higher than that in Influenza A/B- and Human metapneumovirus-positive patients (respectively p=0.014, 0.005). In RSV-positive patients, hospitalization duration and neutrophil, lymphocyte, C-reactive protein level had moderate correlation (respectively; r=0.587; p=0.005, r=-0.436; p=0.038, r=0.498; p=0.022). Conclusion: Despite the limited number of participants from a single center, a wide range of causative pathogens were detected in our study. In addition, we found that viral pathogens are common etiologies of LRTIs. To describe the disease etiology in LRTIs, assays using an RT-MPCR respiratory pathogen panel, would be beneficial to the detection of etiology and treatment.

Increased Colostral Concentration of Macrophage Migration Inhibitory Factor in Mothers with Premature Rupture of Membranes.

Objective: The colostrum contains macrophage migration inhibitory factor (MIF), which plays an important role in protecting newborns from infections. As such, colostrum may be specifically important to prevent early onset neonatal sepsis among neonates born after premature rupture of membranes (PROM). However, the effect of PROM on the colostral MIF concentration has not been previously described. The aim of this study is to compare the concentration of MIF in the colostrum of mothers with and without PROM. Methods: The study group consisted of 44 women, 22 of whom had PROM. Colostrum was expressed and collected within 72 hours of birth. MIF concentration was measured using the enzyme-linked immunosorbent assay method and compared between mothers with and without PROM. Results: There were no differences between the two groups (PROM group n = 22, control group n = 22) with regard to the age of mothers, mode of delivery, neonatal gestational age, birth weight, and sex of the infants (p > 0.05). The colostral MIF concentration was significantly higher among mothers with than without PROM (p = 0.0001). There was a positive and significant correlation between the colostral MIF concentration and PROM duration (r = 0.314, p = 0.038). Conclusions: PROM was associated with a higher colostral MIF concentration, with this concentration being positively correlated with the duration of PROM. This increased concentration may be important in offering these neonates additional protection against early onset infections, which is a risk associated with PROM.

Pentoxifylline in the treatment of neonatal vasospasm and thromboembolism: An observational case series study.

WHAT IS KNOWN AND OBJECTIVE: Newborns, particularly preterm babies, are prone to vascular vasospasm and thromboembolism. Differences in the haemostatic system, small vessel diameter and presence of any serious diseases are predisposing causes of thromboembolic disease in newborns. The lack of randomized controlled studies on the management of vasospasm and thromboembolism exacerbates the problem. We present a case series of the successful and safe use of PTX for the treatment of vasospasm and thrombosis in neonates. METHODS: The study was conducted in the Bezmialem Vakif University Hospital Neonatal Intensive Care Unit (NICU). A retrospective chart review was performed on consecutive patients treated for vascular spasm and thrombosis. Nine patients diagnosed with vasospasm or thrombosis were enrolled in the study. RESULTS: Five patients had arterial injuries. Six patients were premature, and five patients were diagnosed with thrombosis by using Doppler ultrasonography (US). The drug was diluted with 5% dextrose and administered intravenously at a dose of 5 mg/kg/h over six hours, ranging from 1 to 5 days. No drug-related side effects were observed. All babies recovered, and no amputation was performed. WHAT IS NEW AND CONCLUSION: PTX may be an alternative treatment for vascular vasospasm and thromboembolism with fewer side effects than anticoagulant and thrombolytic agents in neonates. Starting PTX in the early stages of vascular insult may prevent the development of vasospasm and thromboembolism and thus limb ischaemia.

Pain Control with Lavender Oil in Premature Infants: A Double-Blind Randomized Controlled Study.

Objectives: Aromatherapy has become popular in pain control in recent years compared with other complementary methods. Lavender (Lavandula angustifolia Miller) is a fragrant essential oil used in aromatherapy for its antibacterial, antifungal, muscle-relaxing, and analgesic effects. The smell of lavender oil, known for its soothing effect on adults, has not been adequately investigated in regards to pain control in premature infants. The purpose of our study was to assign the effect of the scent of lavender oil on pain in preterm infants during heel lancing. Design: A double-blind randomized controlled clinical study. Settings/Location: The study was conducted in a third-level neonatal intensive care unit of Bezmialem Vakif University Hospital from March 2019 to November 2019. It consisted of two groups. Subjects: Sixty-one premature babies (24-37 weeks of gestation) were enrolled in the study. Interventions: Heel stick sampling for metabolic screening was used for both study groups. The interventions were performed by two experienced nurses. Heart rate, oxygen saturation, and the baby's facial expression were recorded by a camera 3 min before the intervention, during the sampling, and 3 min after the procedure. After collecting the data, the head researcher and the assistant researcher separately watched the videos and scored them by using the Premature Infant Pain Profile-Revised (PIPP-R). Outcome measures: The difference of pain scores (PIIP-R) between two groups. Results: There was a statistically significant difference between the two groups in terms of PIPP-R scores during and after the sampling (p = 0.008 and p = 0.03 respectively). The PIPP-R scores at the beginning of the procedure were not found to be significantly different between the groups (p > 0.05). Conclusions: Inhalation of lavender scent is effective in pain control in premature infants. It is safe and low cost; it does not interfere with medical care.

Umbilical cord levels of macrophage migration inhibitory factor in neonatal respiratory distress syndrome

Background/aim: We aimed to evaluate the association of the umbilical cord macrophage migration inhibitory factor (MIF) with the respiratory distress syndrome (RDS) in preterm infants. Materials and methods: A total of eighty six preterm infants (38 with RDS and 48 without RDS) were involved in the study. ELISA is the technique assaying MIF values. Results: The mean of the infants' gestational ages and birth weights were significantly different (P = 0.0001). There were no significant differences in sex, delivery mode or exposure to antenatal steroid among the groups (P > 0.05). Umbilical cord MIF levels of the infants were not correlated with gestational age and birth weight (Spearman's rho = ­0.22 and 0.28 respectively, P > 0.05). There was no statistically significant difference in umbilical cord MIF levels of infants whether or not they were administered antenatal steroid (median:17.88 vs. median:17.60, Mann­Whitney U test, P = 0.42). Cord serum MIF levels were higher (mean, 17.09 ± 5.86 ng/mL) in the RDS group than in the non-RDS group (mean, 14.72 ± 4.18 ng/mL) (P = 0.005). Conclusion: This study shows that, MIF level is higher in the cord blood of the infants with RDS than of the infants without RDS. This supports that MIF expression begins in prior to the birth of the preterm infants and MIF has enhancing impact on the lung development of premature babies. With future studies, the assessment of the cord MIF levels at the bedside may be beneficial for the diagnosis and treatment of RDS, and taking actions to prevent long-term consequences.

Comparison of two different doses of sucrose in pain relief.

BACKGROUND: Procedural pain is one of the most significant problems in neonates, especially in premature babies. Harmless and effective pain relief modalities in newborns should thus be applied. Although sucrose is the most commonly used agent, the most effective dose and concentration of sucrose is not clear. In this study, we compared the efficacy of two different doses of sucrose during venepuncture in neonates. METHODS: This was a prospective, randomized, double-blind study. The study was conducted during venous sampling. Oral 24% sucrose (Tool sweet™ Natus Medical, San Carlos, CA, USA) was given by sterile syringe onto the anterior part of the tongue. Group 1 (n = 65) received 0.2 mL/kg 24% sucrose and group 2 (n = 64) received 0.5 mL/kg 24% sucrose. The Bernese Pain Scale for Neonates (BPSN) was used to assess the pain scores before, during and after the procedure. RESULTS: One hundred and twenty-nine premature infants were enrolled in the study, consisting of 67 girls (51.9%) and 62 boys (48.1%) aged 1-24 days (mean age, 8.34 ± 6.25 days). There was no significant difference in BPSN score between the groups (P > 0.05). There was also no statistically significant difference in BPSN subscale scores between the groups (P > 0.05). CONCLUSIONS: Twenty-four percent sucrose 0.2 mL/kg may be the minimum effective dose to relieve pain during venepuncture procedures in premature babies.

A new case series of Crisponi syndrome in a Turkish family and review of the literature.

Crisponi syndrome/cold-induced sweating syndrome (CS/CISS) is a rare autosomal recessive disorder with a complex phenotype, reported in the neonatal period for CS and in the evolutive one for CISS. The syndrome usually manifests at birth. The aim of this study was to report on three new patients with CS and review the Turkish patients. We report here on three patients from two related families harboring a homozygous mutation in the cytokine receptor-like factor-1 (CRLF1) gene. DNA samples of the three patients and their parents were subjected to a mutational analysis of the CRLF1 gene at the Institute of Biomedical and Genetic Research - National Research Council, Cagliari (Italy). Direct sequencing of the nine coding exons and surrounding intronic regions of CRLF1 was performed using specific primers. All three patients were found to be homozygotes for the mutation c.708_709delinsT, which leads to a frameshift in the second fibronectin type III domain (p.Pro238Argfs*6). CS should be considered in the differential diagnosis of newborns with muscle contractions, feeding and swallowing difficulties, dysmorphic facial findings, camptodactyly, and hypertermia. Neonatologists must be aware of this syndrome that, although very rare worldwide, has a higher prevalence in Turkey.

Use of therapeutic plasma exchange in children with thrombocytopenia-associated multiple organ failure in the Turkish thrombocytopenia-associated multiple organ failure network.

OBJECTIVE: Thrombocytopenia-associated multiple organ failure can lead to high mortality in critically ill children, possibly related to consequences of thrombotic microangiopathy. Plasma exchange therapy may improve thrombotic microangiopathy. The purpose of this observational cohort study is to describe whether there is an association between use of plasma exchange therapy and outcome in the Turkish thrombocytopenia-associated multiple organ failure network. SETTING-INTERVENTIONS: We performed a retrospective cohort analysis in patients with thrombocytopenia-associated multiple organ failure at three different PICUs comparing those who received plasma exchange (+) plus standard therapies with those who did not receive plasma exchange (-) and only received standard therapies. RESULTS: Among 42 of the enrolled patients with thrombocytopenia-associated multiple organ failure, all had a primary or secondary sepsis diagnosis. Fifteen received plasma exchange therapy (PE [+] group) and 27 received standard medical treatment without plasma exchange (PE [-] group). The mean age was 17.69 months (8.24-54.22) in the PE (+) group and 13.46 months (6.47-20.55) in the PE (-) group. Age (p = 0.232), gender (p = 0.206), thrombocyte count (p = 0.09), Organ Failure Index score (p = 0.111), and pediatric logistic organ dysfunction score (p = 0.177) at admission were not statistically different between groups. The overall 28-day mortality was higher in the PE (-) group (70.37%) compared with the PE (+) group (26.67%) (univariate p = 0.006; multivariate controlling for pediatric logistic organ dysfunction, Organ Failure Index, Pediatric Risk of Mortality scores, and neurological failure p = 0.048). Length of stay was increased in the PE (+) group (p = 0.004). CONCLUSIONS: The positive association found between use of plasma exchange therapy and improved survival supports the potential of this therapy in Turkish children with thrombocytopenia-associated multiple organ failure. The positive, although less so, associated treatment effect observed after controlling for illness severity provides further rationale for performing a randomized controlled trial in the pediatric Turkish thrombocytopenia-associated multiple organ failure network. Sample size calculations call for a 100-patient trial with a pre hoc interim analysis after enrollment of 50 patients with thrombocytopenia-associated multiple organ failure.

Therapeutic plasma exchange for malignant refractory status epilepticus: a case report.

BACKGROUND: Refractory status epilepticus is a prolongation of status epilepticus despite anticonvulsant therapy with two or three medications in proper doses; it is defined as malignant status epilepticus if it takes weeks or months. Intravenous immunoglobulin, high-dose steroids, magnesium infusion, pyridoxine, hypothermia, ketogenic diet, electroconvulsive therapy, and surgical therapy are the other treatment options for status epilepticus. PATIENT: Our 5-year-old male patient was hospitalized at our pediatric intensive care unit because of status epilepticus secondary to meningoencephalitis. No response could be obtained with many medical and nonmedical therapies in our patient, who developed malignant status epilepticus with unknown etiology. Therapeutic plasma exchange was applied as convulsions continued. RESULT: Ours is the first child for whom therapeutic plasma exchange was successfully applied because of malignant refractory status epilepticus secondary to meningoencephalitis. CONCLUSION: Therapeutic plasma exchange may be a treatment option for children with refractory status epilepticus following presumed meningoencephalitis.

The evaluation of physiological and biochemical parameters and the autonomic nervous systems of children with breath-holding spells.

AIM: The aim of this study was to investigate the physiological and biochemical parameters of children who are experiencing breath-holding spells (BHS) and to compare the function of their autonomic nervous systems with those of healthy children. PATIENTS AND METHODS: A total of 30 children (age range, 6 months-5 years) admitted for BHS were included in the study. The control group consisted of 30 age-matched and gender-matched healthy children. Each participant underwent a detailed physical examination as well as a laboratory evaluation. Echocardiography, electrocardiography (ECG), and electroencephalography were performed in the study group. The pilocarpine eye test was administered to each participant to detect autonomic dysfunction. RESULTS: No statistically significant differences were found between the groups for mean age, gender, and anthropometric measurements, nor for the biochemical parameters, including hemoglobin concentration, hematocrit, serum iron, transferrin saturation, ferritin, vitamin D, and vitamin B12 levels (p = 0.05). Compared with the control group, the study group showed significantly abnormal hypersensitivity of pupils after instillation of pilocarpine into their eyes (p = 0.01). CONCLUSION: Autonomic dysfunction existed in the children with BHS, but no correlation was found between BHS and deficiencies of iron, vitamin D, or vitamin B12.

Goldenhar's syndrome associated with multiple congenital abnormalities.

Goldenhar's syndrome is characterized by a combination of dermal epibulbar cysts, auricular appendices, malformation of ears, and vertebral anomalies. The average incidence ratio of Goldenhar's syndrome is estimated to be 1/5600, and the frequency of cardiovascular malformations of this syndrome is 5-58 per cent. Although the etiology of this disease is not fully understood, autosomal recessive or dominant inheritance is possible. The disease occurs as sporadic cases. Male:female ratio for the Goldenhar's syndrome is 2:1. A 72-day-old Goldenhar's syndrome case is reported who presented with multiple congenital anomalies.
