The objective of this review is to establish whether embolization is more effective than clinical observation for adult patients with grade III-V splenic injuries. The findings will be used to guide ...future practice and, if necessary, inform future research design and conduct.
The spleen is one of the most frequently injured intra-abdominal organs, with a reported adult mortality of 7% to 18% following trauma. Non-operative management has become a standard of care for hemodynamically stable patients. In clinical practice, the decision whether to prophylactically embolize or manage high-grade injuries with observation alone remains controversial.
Sources including adult patients with grade III-V splenic injuries secondary to blunt trauma will be included in this review. Eligible studies must include comparisons between 2 cohorts of patients undergoing either prophylactic embolization or clinical observation only. Outcomes will include mortality rate, failure of treatment, intensive care unit admission, length of hospital stay, blood transfusion requirements, and patient satisfaction.
A systematic review with meta-analysis will be conducted. PubMed, Embase, and CINAHL will be searched for eligible studies, as will trial registries and sources of gray literature. Study selection, quality appraisal, and data extraction of outcomes will be performed in duplicate. Methodological quality will be evaluated using JBI critical appraisal tools. Studies will, where possible, be pooled in statistical meta-analysis. A random effects model will be used and statistical analysis will be performed. The certainty of the findings will be assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach.

Abstract BACKGROUND SJ-ELIOT (NCT04023669) was a phase 1 trial that explored the combination of the checkpoint kinase inhibitor, prexasertib with the DNA-damaging agents, cyclophosphamide and ...gemcitabine, in recurrent or refractory medulloblastoma. METHODS Participants ≥ 1 year and < 25 years were stratified to one of two treatment strata: stratum A prexasertib and cyclophosphamide and stratum B prexasertib and gemcitabine. Patients with Group 3/4 medulloblastoma were assigned to either stratum A or B, whereas patients with SHH medulloblastoma were assigned to stratum A. A Rolling-6 design was used. RESULTS Fifteen patients were enrolled on stratum A and six patients on stratum B. The study was closed early due to drug supply issues. In stratum A, three patients were escalated to dose level (DL) 3 and none had dose limiting toxicity (DLT). For stratum B, of the first three patients enrolled on DL1, two had DLTs (grade 3 hypotension) related to drug reactions. Consequently, stratum B was amended to add hydrocortisone prophylaxis. A further three patients were enrolled. One patient had a grade 3 DLT (ALT increase). The remaining two patients electively stopped therapy within the first two courses. One patient on stratum A, with SHH TP53 mutant, MYCN amplified medulloblastoma, achieved a complete sustained response, received 12 cycles, and electively stopped treatment after 408 days. They progressed nine months later. The remaining 14 patients on stratum A progressed. There were no objective responses on stratum B. Median PFS were 1.9 and 2.1 months for stratum A and B respectively. CONCLUSIONS The MTD/RP2D was not established for either arm. In stratum A, DL3 was tolerated, whereas DL1 for Stratum B was not tolerated. Despite robust preclinical data, no efficacy signal was observed. Intriguingly, one patient with a highly aggressive tumor (SHH TP53 mutant, MYCN amplified) appeared to derive a sustained benefit from the combination of prexasertib and cyclophosphamide.
Outcomes of extremely low gestational age neonates (ELGANs) may be adversely impacted by packed red blood cell (pRBC) transfusions. We investigated the impact of transfusions on neurodevelopmental ...outcome in the Preterm Erythropoietin (Epo) Neuroprotection (PENUT) Trial population.
This is a post hoc analysis of 936 infants 24-0/6 to 27-6/7 weeks' gestation enrolled in the PENUT Trial. Epo 1000 U/kg or placebo was given every 48 h × 6 doses, followed by 400 U/kg or sham injections 3 times a week through 32 weeks postmenstrual age. Six hundred and twenty-eight (315 placebo, 313 Epo) survived and were assessed at 2 years of age. We evaluated associations between BSID-III scores and the number and volume of pRBC transfusions.
Each transfusion was associated with a decrease in mean cognitive score of 0.96 (95% CI of -1.34, -0.57), a decrease in mean motor score of 1.51 (-1.91, -1.12), and a decrease in mean language score of 1.10 (-1.54, -0.66). Significant negative associations between BSID-III score and transfusion volume and donor exposure were observed in the placebo group but not in the Epo group.
Transfusions in ELGANs were associated with worse outcomes. We speculate that strategies to minimize the need for transfusions may improve outcomes.
Transfusion number, volume, and donor exposure in the neonatal period are associated with worse neurodevelopmental (ND) outcome at 2 years of age, as assessed by the Bayley Infant Scales of Development, Third Edition (BSID-III). The impact of neonatal packed red blood cell transfusions on the neurodevelopmental outcome of preterm infants is unknown. We speculate that strategies to minimize the need for transfusions may improve neurodevelopmental outcomes.
Children born before 28 weeks’ gestation are at increased risk of chronic kidney disease (CKD). Urine biomarkers may shed light on mechanistic pathways and improve the ability to forecast CKD. We ...evaluated whether urinary biomarkers in neonates of low gestational age (GA) are associated with a reduced estimated glomerular filtration rate (eGFR) over time.
A cohort study of neonates with an exploratory case-control study of a subset of the cohort.
327 neonates born at 24-27 weeks’ gestation with 2-year eGFR data from the PENUT (Preterm Erythropoietin Neuroprotection Trial) and the REPaIReD (Recombinant Erythropoietin for Prevention of Infant Renal Disease) study.
11 urinary biomarkers measured at 27, 30, and 34 weeks’ postmenstrual age for the primary cohort study and 10 additional biomarkers for the exploratory case-control study.
eGFR<90mL/min/1.73m2 at 2 years corrected for GA.
Linear mixed models to assess differences in biomarker values between neonates in whom CKD did and did not develop, accounting for multiple comparisons using Bonferroni-Holm correction in the cohort study only. Cohort analyses were adjusted for sex, GA, and body mass index. Cases were matched to controls on these variables in the case-control study.
After adjusting for weeks of GA, urinary levels of α-glutathione-S-transferase (log difference, 0.27; 95% CI, 0.12-0.43), albumin (log difference, 0.13; 95% CI, 0.02-0.25), and cystatin C (log difference, 0.19; 95% CI, 0.04-0.34) were higher in those in whom CKD developed than in those in whom it did not. Urinary albumin and cystatin C levels did not remain significantly different after Bonferroni-Holm correction. In the exploratory case-control analysis, there were no differences in any biomarkers between cases and controls.
Early deaths and a high number of subjects without eGFR at 2 years corrected for GA.
Measurement of urinary biomarkers may assist in monitoring neonates who are at risk for CKD. Additional studies are needed to confirm these findings.

Approximately 15 million neonates worldwide are born prematurely, and 2 million are born before 28 weeks’ gestation. Many of these children go on to experience chronic kidney disease. Urine biomarkers may allow for early recognition of those at risk for the development of kidney disease. In this study of more than 300 children born before 28 weeks’ gestational age, we found higher mean urinary levels of α-glutathione-S-transferase at 27, 30, and 34 weeks in children whose estimated glomerular filtration rate was<90mL/min/1.73m2 at 2 years compared with children whose estimated glomerular filtration rate was>90mL/min/1.73m2 at 2 years. Measurement of urinary biomarkers may assist in monitoring neonates who are at risk for chronic kidney disease. Additional studies are needed to confirm our findings.
Abstract BACKGROUND In response to studies showing medulloblastoma (MB) survival is not only contingent on clinical factors (e.g. metastases, residual disease) but also on molecular factors (e.g. ...molecular group, gene aberrations), we launched the SJMB12 (NCT01878617) trial to stratify treatment using both clinical and molecular risk factors. Specifically, we sought to evaluate if patients with WNT-group MB, without metastatic (M0) or residual disease (R0), treated with reduced-dose craniospinal irradiation (CSI) and reduced-dose cyclophosphamide-based chemotherapy could maintain a high survival with fewer treatment-related side effects. METHODS Tumors were molecularly stratified via immunohistochemistry and fluorescence in-situ hybridization. Patients with WNT tumors were grouped into 3 strata: W1 (M0, R0, classic histology, monosomy of chromosome 6); W2 (M0, R0, without monosomy 6 or classic histology); W3 metastatic (M+), residual disease (R+), or MYC/MYCN amplification. Treatment of W1 consisted of 15-Gy CSI/51-Gy primary site (0.5cm CTV margin) followed by 4 cycles of chemotherapy resulting in cumulative doses of 8 mg/m2 vincristine, 300 mg/m2 cisplatin, 12 gm/m2 cyclophosphamide. Serial audiology, neurocognitive, and endocrine evaluations were conducted over a six-year follow-up period. RESULTS From 2013-2022, 72 patients enrolled onto the W1 stratum: median age was 10.3 years (4.9-22.0); 62.5% female; median time of follow-up was 4.5 years (1.1-10.1). 5-year progression-free survival (PFS) and overall survival were 90.4 ± 5.1% and 98.6 ± 2.1%, respectively. Five patients had PFS events: 4 relapses and 1 accidental death. Relapsed disease was local in 2, distant in 1, and mixed in 1. Time to relapse was > 2 years from enrollment for 3 patients. Severe ototoxicity (SIOP grade ≥ 3) at the end of therapy occurred in 14.4 ± 4.5%. Neurocognitive, endocrine, and detailed molecular data are forthcoming. CONCLUSIONS Patients with low-risk WNT-MB maintained a high PFS (>90%) when treated with reduced-dose CSI and reduced-dose cyclophosphamide-based chemotherapy. Preliminary data suggests fewer treatment-related side effects.
