Comparative Study Observational Study
Conservative Versus Operative Treatment of Proximal Humerus Fractures in Older Individuals—an Analysis of Insurance Data.
Little is known about the frequency and results of conservative treatment of proximal humerus fractures (PHF) in older individuals. ⋯ The conservative treatment of PHF is associated with a lower overall rate of complications due to surgery or trauma, but also with more MAE, more TE, and higher mortality. These findings underline the need for individualized and risk-adjusted treatment recommendations.

The "July Effect" hypothesizes increased morbidity and mortality after the addition of inexperienced physicians at the beginning of an academic year. However, the impact of newer members on neurosurgical teams managing patients with traumatic brain injury (TBI) has yet to be examined. This study conducted a nationwide analysis to evaluate the existence of the "July Effect" in the setting of patients with TBI. ⋯ The findings suggested that there is no "July Effect" on patients with TBI treated at teaching hospitals in the United States.

Acute kidney injury (AKI) is common in hospitalized patients and results in significant morbidity and mortality. The objective of the study was to explore the systemic immune response of intensive care unit patients presenting with AKI, especially the association between immune profiles and persistent AKI during the first week after admission following various types of injuries (sepsis, trauma, surgery, and burns). ⋯ Following various types of severe injuries, early AKI is associated with the initial inflammatory response. Presence of AKI at the end of the first week after injury is associated with injury-induced immunosuppression.

Veterans and active duty service members are significantly more likely to die by suicide using firearms compared to the general population. Not-secure firearm storage (e.g., keeping guns loaded/in an unlocked location) is associated with greater risk for suicide and a third of veteran firearm owners store at least 1 personal firearm unsecured. Veterans and active duty service members are also significantly more likely to be diagnosed with posttraumatic stress disorder (PTSD) than the general population. Symptoms of PTSD are divided into 4 criteria: reexperiencing, avoidance, negative affect, and hyperarousal. Research has suggested that endorsement of hyperarousal symptoms is positively associated with unsecure firearm storage and that avoidance symptoms might be negatively associated with unsecure storage practices. The present study examined the relationship between self-reported firearm ownership and storage practices among each item from the Primary Care PTSD Screening for DSM-IV-TR (PC-PTSD-IV) to explore associations between PTSD features and firearm ownership and storage. ⋯ Results from our study highlight similarities and departures from the previous literature on the connection between PTSD and non-secure firearm storage practices. Further research may examine (1) the relation between PTSD symptoms and firearm storage between active duty service members, retirees, and family members and (2) whether non-response to items regarding firearm ownership is systematic.

Detection of occult hemorrhage (OH) before progression to clinically apparent changes in vital signs remains an important clinical problem in managing trauma patients. The resource-intensiveness associated with continuous clinical patient monitoring and rescue from frank shock makes accurate early detection and prediction with noninvasive measurement technology a desirable innovation. Despite significant efforts directed toward the development of innovative noninvasive diagnostics, the implementation and performance of the newest bedside technologies remain inadequate. This poor performance may reflect the limitations of univariate systems based on one sensor in one anatomic location. It is possible that when signals are measured with multiple modalities in multiple locations, the resulting multivariate anatomic and temporal patterns of measured signals may provide additional discriminative power over single technology univariate measurements. We evaluated the potential superiority of multivariate methods over univariate methods. Additionally, we utilized machine learning-based models to compare the performance of noninvasive-only to noninvasive-plus-invasive measurements in predicting the onset of OH. ⋯ Multivariate ensemble machine learning-based approaches for the prediction of hemodynamic instability appear to hold promise for the development of effective solutions. In the lower body negative pressure multivariate hemorrhage model, predictions based only on noninvasive measurements performed comparably to those using both invasive and noninvasive measurements.
