Elheeny, A. A. H., Tony, G. E.
Journal of endodontics. 2024
Abstract
INTRODUCTION The primary aim of this study was to compare the radiographic changes of immature incisors with periapical radiolucency after treatment with platelet-rich fibrin (PRF) and concentrated growth factor (CGF) platelet concentrate scaffolds as well as assessment of the clinical success rate over 12 months. The secondary aim was to monitor the radiographic changes in terms of reduction of periapical lesion diameter (PALD), root dentine thickness (RDT), root length (RL), and apical foramen width (AFW). The tertiary aim was to assess and pulp responses, after 12 months METHODS Fifty six children withseventy necrotic, single-rooted maxillary incisors with periapical radiolucency were treated with either CGF or PRF scaffolds (35 teeth per group). Two patients with four teeth (two teeth in each group) failed to attain the follow-up recalls. Radiographic changes in terms of reduction of periapical lesion diameter (PALD), root dentine thickness (RDT), root length (RL), and apical foramen width (AFW) were monitored using a two-dimensional radiograph and CBCT scan. The clinical performance of teeth receiving both scaffolds was assessed after 6 and 12 months. Categorical and continuous data were analyzed using the chi-square test and the t-test, respectively. The time and group effects on the means of different radiographic dimensions were tested using the general linear model (GLM). Bland-Altman plots were used to assess the level of agreement between the 2D radiographs and CBCT. The level of significance was defined at 0.05 and a 95% CI. RESULTS The means of PALD and RL showed significant enhancement in the CGF group compared to the PRF group (p< 0.05). While the difference between the two scaffolds in terms of RDT and AFW was not significant (p> .05). The findings of the 2D radiograph and CBCT were consistent. Clinically, both scaffold success rates were similar (93.9%) over the follow-up intervals. The influence of study independent variables had no significant effect on the success of the REPs outcome (p> 0.05). There was no significant difference in the positive pulp responses to the thermal and electric pulp tests after one year of treatment (p> 0.05). CONCLUSIONS According to the short-term follow-up, PRF and CGF were successful in treating immature teeth with periapical radiolucency by regenerative endodontics. Both scaffold systems induced periapical healing and root lengthening with significant superiority of CGF.

Journal of plastic, reconstructive & aesthetic surgery : JPRAS. 2024;90:305-314
Abstract
BACKGROUND NA OBJECTIVE Evaluate the safety and feasibility of platelet-rich plasma (PRP) in the treatment of giant congenital melanocytic nevi (GCMN) in children with human acellular dermal matrix (HADM) transplantation. PATIENTS AND METHODS A total of 22 children with GCMN were included in the study. They were divided into an experimental and a control group. The experimental group used the method of HADM with Razor Autologous Skin Graft combined with PRP to repair skin and soft tissue defects after giant nevus resection (Group A, n = 11). The control group was treated with HADM with Razor Autologous Skin Graft (Group B, n = 11) only. To compare the survival rate of skin grafts, we used the Vancouver Scar Scale (VSS) for the postoperative skin graft area and the Patient and Observer Scar Assessment Scale (POSAS) to compare the two groups of patients. RESULTS There was no statistically significant difference in age, gender, location of giant nevi, and pathological classification between Group A and Group (P > 0.05). The survival rate of skin grafting and the VSS and POSAS scores of scar tissue in group A were superior to those of group B (P < 0.05). CONCLUSIONS PRP has improved the survival rate of composite skin grafting in children with GCMN, and long-term satisfactory prognosis of scar healing. Therefore, we consider this treatment method a valuable contribution to clinical practice.

Abstract
BACKGROUND Open cranial vault reconstruction is the standard technique of craniosynostosis correction that may cause significant blood loss. OBJECTIVES The current study aimed at comparing the effect of tranexamic acid (TXA), controlled hypotension, and their combination on perioperative blood loss and transfusion requirement in craniosynostosis surgery. METHODS The present randomized, double-blind clinical trial was conducted on 75 infants referred for craniosynostosis surgery during 2017 - 2018. Ten minutes before the start of surgery, 10 mg/kg of TXA was administered intravenously to patients in the first group (TXA group). In the second group, patients were subjected to the controlled hypotension anesthesia (CHA) using intravenous remifentanil 0.1 μ/kg (CHA group). In the third group, the patients underwent CHA similar to that of the second group, along with intravenous injection of 10 mg/kg of TXA (CHA-TXA group). Then, patients' mean arterial pressure (MAP), heart rate (HR), total blood loss, and transfusion volume were evaluated and recorded. RESULTS The results of the present study revealed that although the changes in MAP and HR parameters over time (three hours after surgery) were significant in all three groups, the lowest decrease was observed in the CHA-TXA group (P-value < 0.05). In addition, the total perioperative blood loss in the CHA-TXA group with the mean of 181.20 ± 82.71 cc was significantly less than the total perioperative blood loss in the CHA and TXA groups with the means of 262.00 ± 104.04 cc and 212.80 ± 80.75 cc, respectively (P-value < 0.05). Moreover, the transfusion volume in the CHA-TXA group with the mean of 112.40 ± 53.50 cc was significantly lower than the transfusion volume in the CHA and TXA groups with the means of 174.00 ± 73.93 cc and 160.63 ± 59.35 cc, respectively (P-value < 0.05). In contrast, the total blood loss and transfusion volume were not significantly different between the CHA and TXA groups (P-value > 0.05). CONCLUSIONS According to the results of the present study, although the administration of TXA alone could effectively prevent blood loss and was associated with fewer transfusion requirements, the combination of this approach with hypotensive anesthesia resulted in more reduction in perioperative blood loss and transfusion volume as well as better hemodynamic stability.

Tranexamic acid in pediatric hemorrhagic trauma
Borgman, M. A., Nishijima, D. K.
The Journal of Trauma and Acute Care Surgery. 2023;94(1S Suppl 1):S36-s40
Abstract
There is strong evidence in adult literature that tranexamic acid (TXA) given within 3 hours from injury is associated with improved outcomes. The evidence for TXA use in injured children is limited to retrospective studies and one prospective observational trial. Two studies in combat settings and one prospective civilian US study have found association with improved mortality. These studies indicate the need for a randomized controlled trial to evaluate the efficacy of TXA in injured children and to clarify appropriate timing, dose and patient selection. Additional research is also necessary to evaluate trauma-induced coagulopathy in children. Recent studies have identified three distinct fibrinolytic phenotypes following trauma (hyperfibrinolysis, physiologic fibrinolysis, and fibrinolytic shutdown), which can be identified with viscohemostatic assays. Whether viscohemostatic assays can appropriately identify children who may benefit or be harmed by TXA is also unknown.

Cut umbilical cord milking (C-UCM) as a mode of placental transfusion in non-vigorous preterm neonates: a randomized controlled trial
Bora, R. L., Bandyopadhyay, S., Saha, B., Mukherjee, S., Hazra, A.
European journal of pediatrics. 2023
Abstract
Routine practice of delayed cord clamping (DCC) is the standard of care in vigorous neonates. However there is no consensus on the recommended approach to placental transfusion in non-vigorous neonates. In this trial, we tried to examine the effect of cut umbilical cord milking (C-UCM) as compared to early cord clamping (ECC) on hematological and clinical hemodynamic parameters in non-vigorous preterm neonates of 30-35 weeks gestation. The primary outcome assessed was venous hematocrit (Hct) at 48 (± 4) hours of postnatal age. The important secondary outcomes assessed were serum ferritin at 6 weeks of age, mean blood pressure in the initial transitional phase along with important neonatal morbidities and potential complications. In this single centre randomized controlled trial, 134 non vigorous neonates of 30-35 weeks gestation were allocated in a 1:1 ratio to either C-UCM (n = 67) or ECC (n = 67). For statistical analysis, unpaired Student t and Chi square or Fisher's exact test were used. The mean Hct at 48 h was higher in the C-UCM group as compared to the control group, 50.24(4.200) vs 46.16(2.957), p < .0001. Also significantly higher was the mean Hct at 12 h, 6 weeks and mean serum ferritin at 6 weeks of age in the milked group (p < .0001). Mean blood pressure at 1 h and 6 h was also significantly higher in the milked arm. Need for transfusion and inotropes was less in the milked group but not statistically significant. No significant difference in potential complications was observed between the groups. Conclusion: C-UCM stabilizes initial blood pressure and results in higher hematocrit and improved iron stores. It can be an alternative to DCC in non-vigorous preterm neonates of 30-35 weeks' gestation. Further large multicentric studies are needed to fully establish its efficacy and safety. Trial registration: CTRI/2021/12/038606; registration date December 14, 2021. What is Known: • DCC is the routinely recommended method of placental transfusion for vigorous neonates but no consensus exist for neonates requiring resuscitation at birth. • C-UCM is easier to perform in non-vigorous neonates but there is paucity of studies in the preterm population. What is New: • C-UCM is effective as well as safe in non-vigorous preterm neonates of 30-35 weeks gestational age. • C-UCM holds promise as an alternative to DCC, especially in resource limited settings and in situations where the later is not feasible.

Abstract
BACKGROUND Children with thalassemia are generally dependent on blood transfusions and face a lot of stress and alteration in their physiological parameters through the procedure. AIM: This study aimed to investigate the effect of Benson's relaxation technique versus music intervention on physiological parameters and stress of children with thalassemia during blood transfusions. DESIGN A randomized, controlled trial with three parallel groups. METHODS One hundred and twenty preschool-age children with thalassemia who underwent blood transfusions were randomly assigned to three groups. Children of the control group received only routine hospital care through blood transfusions. Music intervention group children listened to recorded Mozart's music and children of Benson's relaxation group received relaxation intervention before and during the blood transfusions. Outcome measures were physiological parameters and behavioral distress levels. SETTING Hematology outpatient clinic of the Children's University Hospital at El-Shatby in Alexandria from October 2022 to February 2023. RESULTS The mean total score of children's behavioral responses to stress before the blood transfusions procedure was 19.32 ± 4.08, 14.20 ± 0.93, and 16.92 ± 4.74 in the control, music, and Benson groups, respectively. Beyond that, there was a decline in their physiological parameters and behavioral stress response during and after procedure among groups of study (P = 0.005 & <0.001, respectively). CONCLUSION Music and Benson's relaxation interventions had a helpful effect on stabilizing the physiological parameters and reducing behavioral distress levels in children with thalassemia undergoing blood transfusions. PRACTICE IMPLICATIONS This study directs paediatric nurses to apply Benson's relaxation and music interventions for children with thalassemia to enhance their responses.

Abstract
BACKGROUND Up to 88% of infants with haemolytic disease of the fetus and newborn who are treated with intrauterine transfusions require erythrocyte transfusions after birth. We aimed to investigate the effect of darbepoetin alfa on the prevention of postnatal anaemia in infants with haemolytic disease of the fetus and newborn. METHODS We conducted an open-label, single-centre, phase 2 randomised controlled trial to evaluate the effect of darbepoetin alfa on the number of erythrocyte transfusions in infants with haemolytic disease of the fetus and newborn. All infants who were treated with intrauterine transfusion and born at 35 weeks of gestation or later at the Leiden University Medical Center, Leiden, Netherlands, were eligible for inclusion. Included infants were randomised by computer at birth to treatment with 10 μg/kg darbepoetin alfa subcutaneously once a week for 8 weeks or standard care (1:1 allocation, in varying blocks of four and six, with no stratification). Treating physicians and parents were not masked to treatment allocation, but the research team, data manager, and statistician were masked to treatment allocation during the process of data collection. The primary outcome was the number of erythrocyte transfusion episodes per infant from birth up to 3 months of life in the modified intention-to-treat population. This trial is registered with ClinicalTrials.gov (NCT03104426) and has been completed. FINDINGS Between Oct 31, 2017, and April 31, 2022, we recruited 76 infants, of whom 44 (58%) were randomly assigned to a treatment group (20 [45%] were allocated to receive darbepoetin alfa and 24 [55%] were allocated to receive standard care). Follow-up lasted 3 months and one infant dropped out of the trial before commencement of treatment. A significant reduction in erythrocyte transfusion episodes was identified with darbepoetin alfa treatment compared with standard care (median 1·0 [IQR 1·0-2·0] transfusion episodes vs 2·0 [1·3-3·0] transfusion episodes; p=0·0082). No adverse events were reported and no infants died during the study. INTERPRETATION Darbepoetin alfa reduced the transfusion episodes after intrauterine transfusion treatment for haemolytic disease of the fetus and newborn. Treatment with darbepoetin alfa or other types of erythropoietin should be considered as part of the postnatal treatment of severe haemolytic disease of the fetus and newborn.

Abstract
OBJECTIVE This study aimed to determine whether or not transfusion of fresh red blood cells (RBCs) reduced the incidence of new or progressive multiple organ dysfunction syndrome compared with standard-issue RBCs in pediatric patients undergoing cardiac surgery. METHODS Preplanned secondary analysis of the Age of Blood in Children in Pediatric Intensive Care Unit study, an international randomized controlled trial. This study included children enrolled in the Age of Blood in Children in Pediatric Intensive Care Unit trial and admitted to a pediatric intensive care unit after cardiac surgery with cardiopulmonary bypass. Patients were randomized to receive either fresh (stored ≤7 days) or standard-issue RBCs. The primary outcome measure was new or progressive multiple organ dysfunction syndrome, measured up to 28 days postrandomization or at pediatric intensive care unit discharge, or death. RESULTS One hundred seventy-eight patients (median age, 0.6 years; interquartile range, 0.3-2.6 years) were included with 89 patients randomized to the fresh RBCs group (median length of storage, 5 days; interquartile range, 4-6 days) and 89 to the standard-issue RBCs group (median length of storage, 18 days; interquartile range, 13-22 days). There were no statistically significant differences in new or progressive multiple organ dysfunction syndrome between fresh (43 out of 89 [48.3%]) and standard-issue RBCs groups (38 out of 88 [43.2%]), with a relative risk of 1.12 (95% CI, 0.81 to 1.54; P = .49) and an unadjusted absolute risk difference of 5.1% (95% CI, -9.5% to 19.8%; P = .49). CONCLUSIONS In neonates and children undergoing cardiac surgery with cardiopulmonary bypass, the use of fresh RBCs did not reduce the incidence of new or progressive multiple organ dysfunction syndrome compared with the standard-issue RBCs. A larger trial is needed to confirm these results.

Abstract
OBJECTIVES The purpose of this study was to investigate and compare the effects of 20 ml/kg and 15 ml/kg red blood cell transfusion (RBCT) on cerebral and intestinal tissue oxygenation, the number of administered transfusions, and neonatal complications in premature infants with anemia. METHODS This prospective, randomized, partially blinded observational study investigated anemic neonates of gestational age < 32 weeks (Registration ID: ChiCTR 1,900,026,672). The infants were randomly assigned to receive 15 or 20 ml/kg red blood cell transfusion. Cerebral and intestinal tissue oxygen saturation (cer rSO(2) and int rSO(2)) were collected 2 h before transfusion, 2, 4, 6, 12, 24, and 48 h after the beginning of transfusion by Near-infrared spectroscopy (NIRS). We also collected vital signs including heart rate (HR), peripheral oxygen saturation (SpO(2)), and mean arterial blood pressure (MABP) 2 h before infusion, 2 h, and 6 h after the beginning of transfusion. Then we analyzed and compared regional oxygen saturation(rSO(2))(,) fractional tissue oxygen extraction (FTOE), and other outcome readouts (blood transfusion numbers, changes in hematocrit and hemoglobin, hospitalization days, HR, SpO2, MABP, and complications) between the two groups. The intraindividual comparisons of the above readouts before transfusion and those after transfusion were also evaluated within each group. RESULT 73 newborns received 20 ml/kg (large volume group) and 78 newborns received 15 ml/kg transfusion (small volume group). There was no significant difference in cer rSO2, int rSO(2), Cerebral fractional tissue oxygen extraction (cFTOE), and intestinal fractional tissue oxygen extraction (iFTOE) between the two groups. rSO(2,) MABP, and SpO(2) increased; HR, cFTOE, and iFTOE decreased following transfusion in both groups. The transfusion number of the large volume group is significantly less than that of the small volume group (1.9 ± 0.3 vs. 2.6 ± 0.9, p < 0.01) and hospitalization days were also less than those in the low volume group (44.3 ± 8.2 vs. 47.6 ± 9.8, p < 0.05). The increases in hematocrit and hemoglobin were higher in the large volume group than those in small volume (hematocrit increment (%),10.7 ± 4.2 vs. 10.1 ± 5.9, p = 0.015; Hb concentration after blood transfusion (g/L) 132.3 ± 11.1 vs. 127.4 ± 15.4, p = 0.028). CONCLUSION After the transfusion, cer rSO2 and int rSO(2) increased significantly, FTOE decreased and vital signs improved in both the 15 ml/kg and 20 ml/kg groups, and these changes were not significantly different between the two groups. However, the larger group showed a more pronounced increase in hematocrit and hemoglobin, a reduction in the total number of transfusions, and a shorter duration of hospitalization after transfusion in preterm infants without increasing complications.
PICO Summary
Population
Premature infants with anaemia (n= 151).
Intervention
15 ml/kg red blood cell transfusion (small volume group, n= 78).
Comparison
20 ml/kg red blood cell transfusion (large volume group, n= 73).
Outcome
There was no significant difference in cerebral tissue oxygen saturation, intestinal tissue oxygen saturation, cerebral fractional tissue oxygen extraction, and intestinal fractional tissue oxygen extraction between the two groups. Regional oxygen saturation, mean arterial blood pressure, and peripheral oxygen saturation increased; heart rate, cerebral fractional tissue oxygen extraction, and intestinal fractional tissue oxygen extraction decreased following transfusion in both groups. The transfusion number of the large volume group was significantly less than that of the small volume group (1.9 ± 0.3 vs. 2.6 ± 0.9) and hospitalization days were also less than those in the low volume group (44.3 ± 8.2 vs. 47.6 ± 9.8,). The increases in haematocrit and haemoglobin were higher in the large volume group than those in small volume (haematocrit increment (%) 10.7 ± 4.2 vs. 10.1 ± 5.9; haemoglobin concentration after blood transfusion (g/L) 132.3 ± 11.1 vs. 127.4 ± 15.4).

Chaudhary, P., Priyadarshi, M., Singh, P., Chaurasia, S., Chaturvedi, J., Basu, S.
European journal of pediatrics. 2023;:1-11
Abstract
Delayed cord clamping (DCC) at delivery has well-recognized benefits; however, current scientific guidelines lack uniformity in its definition. This parallel-group, three-arm assessor-blinded randomized controlled trial compared the effects of three different timings of DCC at 30, 60, and 120 s on venous hematocrit and serum ferritin levels in late preterm and term neonates not requiring resuscitation. Eligible newborns (n = 204) were randomized to DCC 30 (n = 65), DCC 60 (n = 70), and DCC 120 (n = 69) groups immediately after delivery. The primary outcome variable was venous hematocrit at 24 ± 2 h. Secondary outcome variables were respiratory support, axillary temperature, vital parameters, incidences of polycythemia, neonatal hyperbilirubinemia (NNH), need and duration of phototherapy, and postpartum hemorrhage (PPH). Additionally, serum ferritin levels, the incidence of iron deficiency, exclusive breastfeeding (EBF) rate, and anthropometric parameters were assessed during post-discharge follow-up at 12 ± 2 weeks. Over one-third of the included mothers were anemic. DCC 120 was associated with a significant increase in the mean hematocrit by 2%, incidence of polycythemia, and duration of phototherapy, compared to DCC30 and DCC60; though the incidence of NNH and need for phototherapy was similar. No other serious neonatal or maternal adverse events including PPH were observed. No significant difference was documented in serum ferritin, incidences of iron deficiency, and growth parameters at 3 months even in the presence of a high EBF rate. Conclusion: The standard recommendation of DCC at 30-60 s may be considered a safe and effective intervention in the busy settings of low-middle-income countries with a high prevalence of maternal anemia. Trial registration: Clinical trial registry of India (CTRI/2021/10/037070). What is Known: • The benefits of delayed cord clamping (DCC) makes it an increasingly well-accepted practice in the delivery room. • However, uncertainty continues regarding the optimal timing of clamping; this may be of concern both in the neonate and the mother. What is New: • DCC at 120 s led to higher hematocrit, polycythemia and longer duration of phototherapy, without any difference in serum ferritin, and incidence of iron deficiency. • DCC at 30-60 s may be considered a safe and effective intervention in LMICs.
