Demographics in the context of health-care delivery for C1 and C2 fractures.

Introduction: Atlas and axis fractures are the most severe cervical fractures which may result in complete paralysis or death. The purpose of the current study is to identify disparities regarding length of stay (LOS), mortality, and demographic factors in patients with the most serious cervical spine fractures utilizing a nationally representative database.

Materials And Methods: The Nationwide Emergency Department Sample was utilized to provide a representative sample for patients with a primary diagnosis of C1 or C2 fracture presenting to emergency departments in years from October 2015 to December 2019.

Study protocol: Cerebral autoregulation, brain perfusion, and neurocognitive outcomes after traumatic brain injury -CAPCOG-TBI.

Background: Moderate-severe traumatic brain injury (msTBI) stands as a prominent etiology of adult disability, with increased risk for cognitive impairment and dementia. Although some recovery often occurs within the first year post-injury, predicting long-term cognitive outcomes remains challenging, partly due to the significant pathophysiological heterogeneity of TBI, including acute cerebrovascular injury. The primary aim of our recently funded study, cerebral autoregulation, brain perfusion, and neurocognitive outcomes after traumatic brain injury (CAPCOG-TBI), is to determine if acute cerebrovascular dysfunction after msTBI measured using multimodal non-invasive neuromonitoring is associated with cognitive outcome at 1-year post-injury.

Effects of Anion Size, Shape, and Solvation in Binding of Nitrate to Octamethyl Calix[4]pyrrole.

We present cryogenic ion vibrational spectroscopy of complexes of the anion receptor octamethyl calix[4]pyrrole (omC4P) with nitrate in vacuo. We compare the resulting vibrational spectrum with that in deuterated acetonitrile solution, and we interpret the results using density functional theory. Nitrate binds to omC4P through hydrogen bonds between the four NH groups of the receptor and a single NO group of the nitrate ion.

Cryptococcal Osteomyelitis of the Patella: A Case Report.

Case: A 38-year-old woman presented to our clinic with right knee pain and difficulty ambulating. After cultures were obtained, a cryptococcal infection of the patella was identified. Subsequent workup revealed previously undiagnosed HIV/AIDS and a disseminated cryptococcal infection.
