Research has revealed that almost half of relationships will end in divorce or separation when one member experiences a head injury. Many patients are not diagnosed initially, or for several months or years after their injury. Persons dealing with the numerous long-term cognitive and physical problems accompanying mild traumatic brain injury (MTBI) may develop a profound sense of "loss of self." This loss of self, manifest as identity ambiguity on the part of the MTBI subject may be strongly correlated with perceptions of boundary ambiguity on the part of the subject and family resulting from the situation of ambiguous loss. Early recognition and intervention may prevent relational and marital breakdown as well as unnecessary distress to family members. This article discusses the theoretical foundations of our research, preliminary findings of our ongoing qualitative study, and implications for future research and clinical intervention.

Background Trauma centers use guidelines to determine when a trauma surgeon is needed in the emergency department (ED) on patient arrival. A decision rule from Loma Linda University identified patients with penetrating injury and tachycardia as requiring emergent surgical intervention. Our goal was to validate this rule and to compare it to the American College of Surgeons’ Major Resuscitation Criteria (MRC). Study Design We used data from 1993 through 2010 from two Level 1 trauma centers in Denver, Colorado. Patient demographics, injury severity, times of ED arrival and surgical intervention, and all variables of the Loma Linda Rule and the MRC were obtained. The outcome, emergent intervention (defined as requiring operative intervention by a trauma surgeon within one hour of arrival to the ED or performance of cricothyroidotomy or thoracotomy in the ED) was confirmed using standardized abstraction. Sensitivities, specificities, and 95% confidence intervals (CIs) were calculated. Results 8,078 patients were included and 47 (0.6%) required emergent intervention. Of the 47 patients, the median age was 11 years (IQR: 7–14), 70% were male, 30% had penetrating mechanisms, and the median ISS was 25 (IQR: 9–41). At the two institutions, the Loma Linda Rule had a sensitivity and specificity of 69% (95% CI: 45%–94%) and 76% (95% CI: 69%–83%), respectively, and the MRC had a sensitivity and specificity of 80% (95% CI: 70%–92%) and 81% (95% CI: 77%–85%), respectively. Conclusions Emergent surgical intervention is rare in the pediatric trauma population. Although precision of predictive accuracies of the Loma Linda Rule and MRC were limited by small numbers of outcomes, neither set of criteria appears to be sufficiently accurate to recommend their routine use.

Objective: The use of low-dose aspirin for primary prevention of cardiovascular events in patients at elevated risk for cardiovascular disease (CVD) is increasingly being questioned. Aspirin may not benefit this population and may increase the risk of major bleeding events. Data support aspirin use in patients with known CVD.Methods: This is a secondary analysis of de-identified electronic health record (
