Digitization of Symbol-Denoted Blood Pressure Data From Intraoperative Paper Health Records in a Low-Middle-Income Country Using Deep Image Segmentation and Associated Postoperative Outcomes: A Feasibility Study.
In low-middle-income countries (LMICs), perioperative clinical information is almost universally collected on paper health records (PHRs). The lack of accessible digital databases limits LMICs in leveraging data to predict and improve patient outcomes after surgery. In this feasibility study, our aims were to: (1) determine the detection performance and prediction error of the U-Net deep image segmentation approach for digitization of hand-drawn blood pressure symbols from an image of the intraoperative PHRs and (2) evaluate the association between deep image segmentation-derived blood pressure parameters and postoperative mortality and length of stay. ⋯ In this study, we report our experience with a deep image segmentation model for digitization of symbol-denoted blood pressure from intraoperative anesthesia PHRs. Our data support further development of this novel approach to digitize PHRs from LMICs, to provide accessible, curated, and reproducible data for both quality improvement- and outcome-based research.

Utilization of Wearable Pedometer Devices in the Perioperative Period: A Qualitative Systematic Review.
Functional capacity assessment is important for perioperative risk stratification; however, there are currently limited options for objective and economical functional capacity evaluation. Pedometer functions are now widely available in mobile devices and offer a nonintrusive and objective approach to measuring patient activity level over time. Therefore, we conducted this systematic review to assess the value of pedometer readings in predicting perioperative outcomes. ⋯ In addition, in-hospital postoperative pedometer readings correlated with postdischarge complications and readmissions. Perioperative pedometer data demonstrated consistent and biologically plausible association with perioperative outcomes. Further studies are needed to validate the use of pedometer in the perioperative period and to identify the optimal approach for its use to potentially improve patient outcomes.

Observational StudyEnhanced Recovery After Surgery Program and Opioid Consumption in Pulmonary Resection Surgery: A Retrospective Observational Study.
Pulmonary resection surgery causes severe postoperative pain and usually requires opioid-based analgesia, particularly in the early postoperative period. However, the administration of large amounts of opioids is associated with various adverse events. We hypothesized that patients who underwent pulmonary resection under an enhanced recovery after surgery (ERAS) program consumed fewer opioids than patients who received conventional treatment. ⋯ Patients who underwent pulmonary resection under the ERAS program consumed fewer opioids than those who received conventional management while maintaining no significant differences in clinical outcomes.

Role of Tumor Necrosis Factor Receptor 1-Reactive Oxygen Species-Caspase 11 Pathway in Neuropathic Pain Mediated by HIV gp120 With Morphine in Rats.
Recent clinical research suggests that repeated use of opioid pain medications can increase neuropathic pain in people living with human immunodeficiency virus (HIV; PLWH). Therefore, it is significant to elucidate the exact mechanisms of HIV-related chronic pain. HIV infection and chronic morphine induce proinflammatory factors, such as tumor necrosis factor (TNF)α acting through tumor necrosis factor receptor I (TNFRI). HIV coat proteins and/or chronic morphine increase mitochondrial superoxide in the spinal cord dorsal horn (SCDH). Recently, emerging cytoplasmic caspase-11 is defined as a noncanonical inflammasome and can be activated by reactive oxygen species (ROS). Here, we tested our hypothesis that HIV coat glycoprotein gp120 with chronic morphine activates a TNFRI-mtROS-caspase-11 pathway in rats, which increases neuroinflammation and neuropathic pain. ⋯ These results suggest that spinal TNFRI-mtROS-caspase 11 signal pathway plays a critical role in the HIV-associated neuropathic pain state, providing a novel approach to treating chronic pain in PLWH with opioids.

Maternal Cardiovascular Morbidity Events Following Preeclampsia: A Retrospective Cohort Study.
Patients with preeclampsia are at high risk for long-term cardiovascular events, yet the short-term, acute cardiovascular complications that follow preeclampsia are understudied. The objective of this study was to compare the short-term, acute maternal cardiovascular morbidity events after delivery among patients with a diagnosis of preeclampsia versus those without this diagnosis. ⋯ Patients with both preeclampsia and preeclampsia with severe features have higher rates of maternal cardiovascular morbidity events than those without preeclampsia. Future studies are necessary to examine which patients with preeclampsia are at highest risk for cardiovascular complications.
