Observational StudyPresurgical Thalamus Volume in Postoperative Delirium: A Longitudinal Observational Cohort Study in Older Patients.
Previous studies suggest a role of the thalamus in cognitive function, while others implicate it as a central effect site of anesthetics. Yet, its role in postoperative neurocognition in the aging brain remains uncertain. We used presurgical thalamic volume as a functional indicator and determined its association with postoperative delirium (POD). ⋯ A larger thalamus volume was associated with reduced odds of POD. Thus, the thalamus marks a region of interest in POD in the aging brain. These findings may help to understand the neuronal basis of POD.

Racial Disparities in the Use of Peripheral Nerve Blocks for Postoperative Analgesia After Total Mastectomy: A Retrospective Cohort Study.
Peripheral nerve blocks (PNBs) are used to provide postoperative analgesia after total mastectomy. PNBs improve patient satisfaction and decrease postoperative opioid use, nausea, and vomiting. Few studies have examined whether there is racial-ethnic disparity in the use of PNBs for patients having total mastectomy. We hypothesized that non-Hispanic Asian, non-Hispanic Black, non-Hispanic patients of other races, and Hispanic patients would be less likely to receive a PNB for postoperative analgesia compared to non-Hispanic White patients having total mastectomy. Secondarily, we hypothesized that PNBs would be associated with reduced odds of major complications after total mastectomy. ⋯ Significant disparity exists in the use of PNBs for postoperative analgesia in patients of different race-ethnicity who undergo total mastectomy in the United States. Continued efforts are needed to better understand the causes of disparity and to ensure equitable access to PNBs.

Bedside Diagnosis of Pulmonary Embolism Using Electrical Impedance Tomography: A Case Report.
Electrical impedance tomography (EIT) is an emerging imaging modality that can be used to diagnose ventilatory and intrathoracic perfusion mismatches in unstable patients at the bedside. We present a case of a postoperative hypoxic patient in the intensive care unit (ICU) who was too unstable for transport for computed tomography (CT) imaging but was diagnosed and treated for a pulmonary embolism using EIT at the bedside. After the patient clinically improved, CT imaging confirmed the pulmonary embolism diagnosis. EIT is a promising diagnostic tool that may have great utility in ICUs, where it can be safely applied at the bedside.
