Blast injuries in children: a mixed-methods narrative review.

ABSTRACT: Background and significance:Blast injuries arising from high explosive weaponry is common in conflict areas. While blast injury characteristics are well recognised in the adults, there is a lack of consensus as to whether these characteristics translate to the paediatric population. Understanding blast injury patterns in this cohort is essential for providing appropriate provision of services and care for this vulnerable cohort. Methods:In this mixed-methods review, original papers were screened for data pertaining to paediatric injuries following blasts. Information on demographics, morbidity and mortality, and service requirements were evaluated. The papers were written and published in English from a range of international specialists in the field. Results:Children affected by blast injuries are predominantly male and their injuries arise from explosive remnants of war, particularly unexploded ordinance. Blasts show increased morbidity and mortality in younger children, while older children have injury patterns similar to adults. Head and burn injuries represent a significant cause of mortality in young children, while lower limb morbidity is reduced compared with adults. Children have a disproportionate requirement for both operative and non-operative service resources, and provisions for this burden are essential. Conclusions:Certain characteristics of paediatric injuries arising from blasts are distinct from that of the adult cohort, while the intensive demands on services highlight the importance of understanding the diverse injury patterns in order to optimise future service provisions in caring for this child blast survivor.

Project description:BackgroundUsing race-a socially assigned identity that does not adequately capture human genetic variation-to guide clinical care can result in poor outcomes for racially minoritized patients. This study assessed (1) how physicians conceptualize and use race in their clinical care (race-based care) and (2) physician characteristics associated with race-based care.MethodsPubMed, CINAHL, EMBASE, and Scopus databases were searched. Qualitative, quantitative, and mixed-methods studies written in peer-reviewed, English-language journal articles evaluating US physicians' perceptions of race and physician factors associated with race-based care were included. Risk of bias was assessed using the Mixed Methods Appraisal Tool. Qualitative studies were evaluated using thematic analysis, and quantitative findings were summarized and combined with qualitative findings in a narrative synthesis.ResultsA total of 1149 articles were identified; 9 (4 qualitative, 5 quantitative) studies met inclusion criteria. Five themes emerged: (1) the belief in race as biological; (2) the use of race to contextualize patients' health; (3) the use of race to counsel patients and determine care; (4) justifications for race-based practice (evidence-based, personal experience, addresses disparities, provides personalized care, increases compliance); and (5) concerns with race-based practice (poorly characterizes patients, normalizes disparities, patient distrust, clinician discomfort, legitimized biological race). In quantitative studies, older age was positively associated with race-based care.DiscussionPhysicians had varied perceptions of race, but many believed race was biological. Concern and support for race-based practice were related to beliefs regarding the evidence for using race in care and the appropriateness of race as a variable in medical research. Older physicians were more likely to use race, which could be due to increased exposure to race-based medical literature, in addition to generational differences in conceptualizations of race. Additional research on the evolution of physicians' perceptions of race, and the role of medical literature in shaping these perceptions, is needed.

Project description:In the military, explosive blasts are a significant cause of mild traumatic brain injuries (mTBIs). The symptoms associated with blast mTBIs causes significant economic burdens and a diminished quality of life for many service members. At present, the distinction of the injury mechanism (blast versus non-blast) may not influence TBI diagnosis. However, using noninvasive imaging, this study reveals significant distinctions between the blast and non-blast TBI mechanisms. A cortical whole-brain thickness analysis was performed using structural high-resolution T1-weighted MRI to identify the effects of blasts in persistent mTBI (pmTBI) subjects. A total of 41 blast pmTBI subjects were individually age- and gender-matched to 41 non-blast pmTBI subjects. Using FreeSurfer, cortical thickness was quantified for the blast group, relative to the non-blast group. Cortical thinning was identified within the blast mTBI group, in two clusters bilaterally. In the left hemisphere, the cluster overlapped with the lateral orbitofrontal, rostral middle frontal, medial orbitofrontal, superior frontal, rostral anterior cingulate and frontal pole cortices (p < 0.02, two-tailed, size = 1680 mm2). In the right hemisphere, the cluster overlapped with the lateral orbitofrontal, rostral middle frontal, medial orbitofrontal, pars orbitalis, pars triangularis and insula cortices (p < 0.002, two-tailed, cluster size = 2453 mm2). Self-report assessments suggest significant differences in the Post-Traumatic Stress Disorder Checklist-Civilian Version (p < 0.05, Bonferroni-corrected) and the Neurobehavioral Symptom Inventory (p < 0.01, uncorrected) between the blast and non-blast mTBI groups. These results suggest that blast may cause a unique injury pattern related to a reduction in cortical thickness within specific brain regions which could affect symptoms. No other study has found cortical thickness difference between blast and non-blast mTBI groups and further replication is needed to confirm these initial observations.
