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., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Misirlioglu, Yildizdas, Ekinci, Ozgur Horoz, Tumgor, Yontem, Talay, Kangin, Tufan, Kesici, Yener, Kinik Kaya, Havan, Tunc, Akçay, Sevketoglu, Durak, Ozel Dogruoz, Ozcan, Perk, Duyu, Boyraz, Uysal Yazici, Ozturk, Çeleğen, Bukulmez, Kacmaz, Dinleyici, Dursun, Koker, Bayraktar, Talip Petmezci, Nabaliyeva, Agin, Hepduman, Akkuzu, Kendirli, Ozen, Topal, Ödek, Ozkale, Ozkale, Atay, Erdoğan, Konca, Yapici, Arslan, Besci, Yilmaz, Gumus, Oto, Dalkiran, Mercan, Çoban, Ipek, Gungor, Arslankoylu, Alakaya, Sari, Yucel and Yazar.)

Microbiota composition might play a role in the pathophysiology and course of sepsis, and understanding its dynamics is of clinical interest. Invasive meningococcal disease (IMD) is an important cause of community-acquired serious infection, and there is no information regarding microbiota composition in children with meningococcemia. In this study, we aimed to evaluate the intestinal and nasopharyngeal microbiota composition of children with IMD. Materials and Methods: In this prospective, multi-center study, 10 children with meningococcemia and 10 age-matched healthy controls were included. Nasopharyngeal and fecal samples were obtained at admission to the intensive care unit and on the tenth day of their hospital stay. The V3 and V4 regions of the 16S rRNA gene were amplified following the 16S Metagenomic Sequencing Library Preparation. Results: Regarding the alpha diversity on the day of admission and on the tenth day at the PICU, the Shannon index was significantly lower in the IMD group compared to the control group ( p = 0.002 at admission and p = 0.001, on the tenth day of PICU). A statistical difference in the stool samples was found between the IMD group at Day 0 vs. the controls in the results of the Bray-Curtis and Jaccard analyses ( p = 0.005 and p = 0.001, respectively). There were differences in the intestinal microbiota composition between the children with IMD at admission and Day 10 and the healthy controls. Regarding the nasopharyngeal microbiota analysis, in the children with IMD at admission, at the genus level, Neisseria was significantly more abundant compared to the healthy children ( p < 0.001). In the children with IMD at Day 10, genera Moraxella and Neisseria were decreased compared to the healthy children. In the children with IMD on Day 0, for paired samples, Moraxella , Neisseria , and Haemophilus were significantly more abundant compared to the children with IMD at Day 10. In the children with IMD at Day 10, the Moraxella and Neisseria genera were decreased, and 20 different genera were more abundant compared to Day 0. Conclusions: We first found alterations in the intestinal and nasopharyngeal microbiota composition in the children with IMD. The infection itself or the other care interventions also caused changes to the microbiota composition during the follow-up period. Understanding the interaction of microbiota with pathogens, e.g., N. meningitidis , could give us the opportunity to understand the disease's dynamics.

Although the most common symptoms of coronavirus disease 2019 (COVID-19) in children are fever and cough, cases of croup associated with COVID-19 are reported in the literature and have increased sharply with the Omicron variant. We present severe acute respiratory syndrome coronavirus 2 as a viral agent in an infant presenting with croup., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2022 Wolters Kluwer Health, Inc.

Introduction: There have been some significant changes regarding healthcare utilization during the COVID-19 pandemic. Majority of the reports about the impact of the COVID-19 pandemic on diabetes care are from the first wave of the pandemic. We aim to evaluate the potential effects of the COVID-19 pandemic on the severity of diabetic ketoacidosis (DKA) and new onset Type 1 diabetes presenting with DKA, and also evaluate children with DKA and acute COVID-19 infection., Methods: This is a retrospective multi-center study among 997 children and adolescents with type 1 diabetes who were admitted with DKA to 27 pediatric intensive care units in Turkey between the first year of pandemic and pre-pandemic year., Results: The percentage of children with new-onset Type 1 diabetes presenting with DKA was higher during the COVID-19 pandemic ( p < 0.0001). The incidence of severe DKA was also higher during the COVID-19 pandemic ( p < 0.0001) and also higher among children with new onset Type 1 diabetes ( p < 0.0001). HbA1c levels, duration of insulin infusion, and length of PICU stay were significantly higher/longer during the pandemic period. Eleven patients tested positive for SARS-CoV-2, eight were positive for new onset Type 1 diabetes, and nine tested positive for severe DKA at admission., Discussion: The frequency of new onset of Type 1 diabetes and severe cases among children with DKA during the first year of the COVID-19 pandemic. Furthermore, the cause of the increased severe presentation might be related to restrictions related to the pandemic; however, need to evaluate the potential effects of SARS-CoV-2 on the increased percentage of new onset Type 1 diabetes., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Kiral, Kirel, Havan, Keskin, Karaoglan, Yildirim, Kangin, Talay, Urun, Altug, Kesici, Tufan, Kacmaz, Bozan, Azapagasi, Uysal Yazici, Ozturk, Yesilbas, Karaguzel, Kaya, Barlas, Duyu, Boyraz, Sevketoglu, Akcay, Hancili, Guven, Dursun, Ulgen Tekerek, Ozcifci, Yazici, Turanli, Kendirli, Kahveci, Yetimakman, Citak, Şik, Bingol, Aygun, Durak, Yilmaz, Bugrul, Sari, Tekguç, Albayrak, Yener, Agin, Soydan, Yildizdas, Dilek, Yalindag, Incekoy-Girgin, Alacakir, Tutunculer, Arslanaoglu, Aydin, Bilgin, Simsek and Dinleyici.)

Aim: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection may result in a life-threatening hyperinflammatory condition named multisystem inflammatory syndrome in children (MIS-C). We aimed to assess demographics, clinical presentations, laboratory characteristics and treatment outcomes of patients with MIS-C., Methods: We performed a retrospective study of patients with MIS-C managed between August 2020 and March 2021 at Dr. Sami Ulus Maternity Child Health and Diseases Training and Research Hospital in Turkey., Results: A total of 45 patients (23 male, 51%) with a median age of 8.7 years (interquartile range: 5.6-11.7 years) were enrolled to study. The SARS-CoV-2 serology was positive in 43 (95%) patients. Organ-system involvement included the dermatologic in 41 (91%), cardiovascular in 39 (87%), hematologic in 36 (80%) and gastrointestinal in 36 (80%) patients. Acute anterior uveitis was diagnosed in nine (20%) patients. Two patients presented with clinical findings of deep neck infection such as fever, neck pain, trismus, swelling and induration on the cervical lymph node. One patient presented with Henoch-Schonlein purpura-like eruption. Coronary artery dilatation was detected in five (11%) patients. For treatment of MIS-C, intravenous immunoglobulin was used in 44 (98%) patients, methylprednisolone in 27 (60%) and anakinra in 9 (20%) patients. The median duration of hospitalisation was nine days. All patients recovered., Conclusions: Children with MIS-C might have variable clinical presentations. Acute anterior uveitis might be a prominent presentation of MIS-C and require ophthalmological examination. It is essential to make patient-based decisions and apply a stepwise approach for the treatment of this life-threatening disease., (© 2021 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).)

Aim of the Study: Successful cardiopulmonary resuscitation and early defibrillation are critical in survival after in- or out-of-hospital cardiopulmonary arrest. The scope of this multi-centre study is to (a) assess skills of paediatric healthcare providers (HCPs) concerning two domains: (1) recognising rhythm abnormalities and (2) the use of defibrillator devices, and (b) to evaluate the impact of certified basic-life-support (BLS) and advanced-life-support (ALS) training to offer solutions for quality of improvement in several paediatric emergency cares and intensive care settings of Turkey., Methods: This cross-sectional and multi-centre survey study included several paediatric emergency care and intensive care settings from different regions of Turkey., Results: A total of 716 HCPs participated in the study (physicians: 69.4%, healthcare staff: 30.6%). The median age was 29 (27-33) years. Certified BLS-ALS training was received in 61% (n = 303/497) of the physicians and 45.2% (n = 99/219) of the non-physician healthcare staff (P < .001). The length of professional experience had favourable outcome towards an increased self-confidence in the physicians (P < .01, P < .001). Both physicians and non-physician healthcare staff improved their theoretical knowledge in the practice of synchronised cardioversion defibrillation (P < .001, P < .001). Non-certified healthcare providers were less likely to manage the initial doses of synchronised cardioversion and defibrillation: the correct responses remained at 32.5% and 9.2% for synchronised cardioversion and 44.8% and 16.7% for defibrillation in the physicians and healthcare staff, respectively. The indications for defibrillation were correctly answered in the physicians who had acquired a certificate of BLS-ALS training (P = .047, P = .003)., Conclusions: The professional experience is significant in the correct use of a defibrillator and related procedures. Given the importance of early defibrillation in survival, the importance and proper use of defibrillators should be emphasised in Certified BLS-ALS programmes. Certified BLS-ALS programmes increase the level of knowledge and self-confidence towards synchronised cardioversion-defibrillation procedures., (© 2021 John Wiley & Sons Ltd.)

Thrombotic thrombocytopenic purpura (TTP) is a rare, dangerous, life-threatening disease characterized by microangiopathic hemolytic anemia and thrombocytopenia, along with organ dysfunction due to microangiopathy-related ischemia. Plasma exchange and steroids are used for initial treatment, and rituximab is often used in refractive patients. Caplacizumab, cyclophosphamide, and splenectomy are among other treatment options. It has been reported that bortezomib, a proteasome inhibitor, can be used in the management of refractory acquired TTP. Herein, we present a 16-year-old female patient who was monitored for acquired TTP and treated with high-dose steroids, plasma exchange, rituximab, cyclophosphamide, and N-acetylcysteine but developed renal, cardiac, gastrointestinal, and neurologic complications. The girl was then successfully treated with bortezomib, and she has been monitored in remission for 6 months. We consider that bortezomib is a beneficial treatment, especially in patients with refractory TTP., Competing Interests: The authors declare no conflict of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

The aim of this study is to evaluate a novel oxidative stress marker (thiol-disulphide homeostasis) in paediatric sepsis and to determine their effects on the prognosis of sepsis. Patients diagnosed with sepsis (n= 38) and healthy controls (n= 40) were incorporated in the study. Total thiol, native thiol, disulphide, disulphide/total thiol, disulphide/native thiol, and native thiol /total thiol levels were measured in the sepsis and control groups. Additionally, the parameters were compared between survivors and non-survivors in the sepsis group. The levels of hemoglobin, white blood cell, platelet, lactate, and C-reactive protein were measured in patients with sepsis at diagnosis. The paediatric risk of mortality and paediatric logistic organ dysfunction scores of the patients were used to estimate the disease severity. The plasma thiol levels of the patients with sepsis were significantly lower than the control group (p < 0.001). This study showed that thiol/disulphide homeostasis is abnormal in children with sepsis in Paediatric Intensive Care Unit., Competing Interests: The authors report no conflicts of interest in this work., (Sociedad Argentina de Pediatría.)

Introduction: Recent improvements in pediatric intensive care units (PICUs) were achieved through trained personnel and better technology, leading to an increase in patient care, survival rates and good prognosis. Nevertheless the quality of care varies according to the availability of human and technical resources., Objective: The aim was to determine the correlation of mortality rates with daytime shifts compared to other shift periods (off-hours)., Methods: Work hours were defined as week days between 8:00 a.m. and 5:00 p.m., with in-house attendance of senior staff, and off-hours as week days between 5:00 p.m. and 8:00 a.m., weekends and public holidays, with one resident covering the PICU and senior staff directly available only on-call. Mortality causes in children hospitalized in the intensive care unit were classified., Results: During this period, a total of 2,187 patients were hospitalized in the PICU. A total of 394 patients died; 151 were girls (38.3 %) and 243 boys (61.7 %). Evaluating time of mortality showed that death occurred mostly at out-off hours: 244 (61.9 %) vs. 150 (38.1 %) during the daytime shift, which was statistically significant (p < 0.05). In addition, age, gender and the length of stay in the PICU were not significant (p > 0.05) when daytime was compared to out-off hours. The conditions which accompanied death were evaluated, the relationship between working hours and death was also significant (p < 0.05). More conditions related to mortality were encountered at off-hours., Conclusion: Off-hours without 24 hour attendance of senior staff, was associated with higher mortality., (Sociedad Argentina de Investigación Odontológica.)
