Prevalence Of Unplanned Readmissions Among Patients Of Military Treatment Facilities.

Understanding readmissions within the Military Health System (MHS) provides important insights to better understand and improve health outcomes for military personnel and their families. We assessed all-cause seven- and thirty-day readmission rates in military treatment facilities by treatment service for patients ages 18-64 for fiscal years 2011-18 using inpatient data from the MHS and the private sector. We compared unplanned readmission rates for the obstetric, medical, and surgical product lines.

A Surgical Business Composite Score for Army Medicine.

Measuring surgical business performance for Army military treatment facilities is currently done through 6 business metrics developed by the Army Medical Command (MEDCOM) Surgical Services Service Line (3SL). Development of a composite score for business performance has the potential to simplify and synthesize measurement, improving focus for strategic goal setting and implementation. However, several considerations, ranging from data availability to submetric selection, must be addressed to ensure the score is accurate and representative.

Impairment of intracerebral arteriole dilation responses after subarachnoid hemorrhage. Laboratory investigation.

Object: Cerebrovascular dysfunction after subarachnoid hemorrhage (SAH) may contribute to ischemia, but little is known about the contribution of intracerebral arterioles. In this study, the authors tested the hypothesis that SAH inhibits the vascular reactivity of intracerebral arterioles and documented the time course of this dysfunction.

Methods: Subarachnoid hemorrhage was induced using an endovascular filament model in halothane-anesthetized male Sprague-Dawley rats.

Correlation of intrinsic optical signal, cerebral blood flow, and evoked potentials during activation of rat somatosensory cortex.

Object: This study was undertaken to test the hypothesis that cerebral blood flow (CBF) and the intrinsic optical signal could be dissociated by altering adenosine receptor activity and to uncover the origin of the optic signal using a cranial window in the anesthetized rat.

Methods: In anesthetized, ventilated, and temperature-controlled rats with closed cranial windows, the authors evaluated simultaneously the alterations in pial arteriolar diameter, intrinsic optical signals (690 nm), and somatosensory evoked potentials during cortical activation evoked by contralateral sciatic nerve stimulation (SNS). To dissociate the vascular and intrinsic signal, they topically applied the adenosine receptors antagonists theophylline (5 microM), which affects A1 and A2A receptors, and 8-cyclopentyl-1,3-dipropylxanthine (CPX, 1 microM), which blocks the A(1) receptor.

Subarachnoid hemorrhage model in the rat: modification of the endovascular filament model.

The present study describes modifications to the endovascular filament model of subarachnoid hemorrhage (SAH) in rats. Specifically, we sought to improve the percentage yield of SAH, reduce mortality rates and better simulate human cerebral aneurysmal rupture. Instead of using a 4-0 prolene suture to induce SAH in the existing endovascular filament model, a hollow and flexible polyetrafluoroethylene (PTFE) tube was maneuvered into the proximal anterior cerebral artery (ACA) to ensure that advancement occurred without producing trauma to the vessels.
