AbstractObjectiveThis study compares the developmental and functional outcomes at school entry between boys and girls born with a congenital cardiac defect who required early surgical correction.Study designA prospective cohort of 94 children, including 49 percent boys, were followed up to 5 years of age and assessed for developmental progress. Developmental measures included Wechsler Preschool and Primary Scale of Intelligence – cognitive; Peabody Picture Vocabulary Test – receptive language; Peabody Developmental Motor Scale – motor; and Child Behaviour Checklist – behaviour. Measures of function included the Vineland Adaptive Behavior Scale and Functional Independence Measure for Children (WeeFIM).ResultsThe mean scores of the boys on the WeeFIM subscales, such as self-care, mobility, cognition, were significantly lower than that of the girls. There was a trend for a greater proportion of boys to have abnormalities on neurological examination (boys 37.5 percent abnormal, girls 19.5 percent abnormal). Verbal, performance, and full scale Intellectual Quotients were 5–7 points lower in boys but did not reach significance (full scale Intellectual Quotient: boys 87.7 plus or minus 22.2; girls 93.9 plus or minus 19.3). Boys were more likely to have fine motor delays (50 percent, 82.7 plus or minus 16.5) compared with girls (28.2 percent, 87.0 plus or minus 15.8). There were no gender differences in receptive language or behavioural difficulties.ConclusionsBoys born with congenital heart disease requiring early surgical repair appear to be at enhanced risk for neuromotor impairments and activity limitations. Findings support gender differences in the pathogenesis of early brain injury following hypoxic–ischaemic insults. This has implications for neuroprotective strategies to prevent brain injury.

Hospital Cardiac Arrest

Introduction: Every year about 70% of coronary heart disease deaths in the United States occur out of hospital, usually presenting as ‘sudden death’ due to cardiac arrest. Despite the improvement of survival with advanced cardiac interventions, mortality remains high. Therapeutic hypothermia (TH) has been shown to be neuroprotective after cardiac arrest. We explored factors associated with good recovery of neurological function following out-of-hospital cardiac arrest (OHCA). Methods: This retrospective study included review of electronic medical records from a major healthcare system in Northeast Indiana. Individuals who suffered OHCA from January 2011 to June 2014 were included. Neurological function was evaluated by Modified Rankin Scale (mRS) at discharge. The neurological outcome was defined as good (mRS 0-3), poor (mRS 4-5), and deceased (mRS 6) to assess the association of examined variables. Results: Among the 111 patients meeting inclusion criteria, the mortality at discharge was 68.6% in TH-treated patients and 84% in normothermia patients. For almost half (47.5%) of the patients undergoing TH who died prior to discharge, brain-related causes were the primary cause of death. 21 patients who had imaging or pathological examinations all showed evidences of ischemic brain injury. Among TH-treated survivors, patients with return of spontaneous cardiac rhythm (ROSC) within 20 minutes of onset were 1.4 times the odds more likely to have a good neurological outcome at discharge (p=0.02). Patients with ventricular fibrillation had 2 times the odds more likely retaining good neurological function at discharge after receiving TH treatment (p=0.012). The time to initiate TH (mean 2.3 ± 1.5 hours) and time to reach target temperature (mean 7.2 ± 2.3 hours) were not associated with neurological outcome at discharge. Conclusions: Initial rhythm and time to ROSC were identified as reliable predictors of good neurological function following OHCA. TH has been found to be insufficient in preventing brain injury. This study emphasizes the need for future studies to develop new neuroprotective strategies to improve survival among OHCA patients.

Underlying Pathophysiology

Traumatic brain injury (TBI) is the leading cause of mortality and morbidity in the younger population worldwide. Survivors of TBI often experience long-term disability in the form of cognitive, sensorimotor, and affective impairments. Despite the high prevalence in, and cost of TBI to, both individuals and society, some of its underlying pathophysiology is not completely understood. Animal models have been developed over the past few decades to closely replicate the different facets of TBI in humans to better understand the underlying pathophysiology and behavioral impairments and assess potential therapies that can promote neuroprotection. However, no effective treatment for TBI has been established to date in the clinical setting, despite promising results generated in preclinical studies in the use of neuroprotective strategies. The failure to translate results from preclinical studies to the clinical setting underscores a compelling need to revisit the current state of knowledge in the use of animal models in TBI.
