Antiplatelet Reversal Is Not Associated With Decreased Progression of Intracranial Hemorrhage in Near-Isolated Traumatic Brain Injury: A Retrospective Clustered Analysis From Two Trauma Centers.

Introduction: Antiplatelet agents (AAs) may increase the risk of intracranial hemorrhage (ICH). It is unclear whether reversal of antiplatelet effects (REV = desmopressin acetate [DDAVP] + Platelets) decreases ICH progression. The goal of the study was to determine whether REV was associated with decreased progression of ICH on repeat brain computed tomography (CT) scan.

Warfarin, not direct oral anticoagulants or antiplatelet therapy, is associated with increased bleeding risk in emergency general surgery patients: Implications in this new era of novel anticoagulants: An EAST multicenter study.

Introduction: This study aimed to assess perioperative bleeding complications and in-hospital mortality in patients requiring emergency general surgery presenting with a history of antiplatelet (AP) versus direct oral anticoagulant (DOAC) versus warfarin use.

Methods: A prospective observational study across 21 centers between 2019 and 2022 was conducted. Inclusion criteria were age 18 years or older, and DOAC, warfarin, or AP use within 24 hours of an emergency general surgery procedure.

Anticoagulation in emergency general surgery: Who bleeds more? The EAST multicenter trials ACES study.

Background: While direct oral anticoagulant (DOAC) use is increasing in the Emergency General Surgery (EGS) patient population, our understanding of their bleeding risk in the acute setting remains limited. Therefore, the objective of this study was to determine the prevalence of perioperative bleeding complications in patients using DOACs versus warfarin and AP therapy requiring urgent/emergent EGS procedures (EGSPs).

Methods: This was a prospective observational trial, conducted between 2019 and 2022, across 21 centers.

Does lower extremity fracture fixation technique influence neurologic outcomes in patients with traumatic brain injury? The EAST Brain vs. Bone multicenter trial.

Objective: This study aimed to determine whether lower extremity fracture fixation technique and timing (≤24 vs. >24 hours) impact neurologic outcomes in TBI patients.

Methods: A prospective observational study was conducted across 30 trauma centers.

Low Prevalence but High Impact of COVID-19 Positive Status in Adult Trauma Patients: A Multi-institutional Analysis of 28 904 Patients.

Background: Few large investigations have addressed the prevalence of COVID-19 infection among trauma patients and impact on providers. The purpose of this study was to quantify the prevalence of COVID-19 infection among trauma patients by timing of diagnosis, assess nosocomial exposure risk, and evaluate the impact of COVID-19 positive status on morbidity and mortality.

Methods: Registry data from adults admitted 4/1/2020-10/31/2020 from 46 level I/II trauma centers were grouped by: timing of first positive status (Day 1, Day 2-6, or Day ≥ 7); overall Positive/Negative status; or Unknown if test results were unavailable.

Where to Draw the Line for Intracranial Hypertension; Opening Pressures and Mortality.

Background: Intracranial pressure (ICP) monitoring and treatment is a mainstay of severe TBI management but the relationship between intracranial opening pressure (OP) and outcomes has not been well established. The purpose of our study was to assess the relationship between OP and outcomes in severe TBI patients, with a focus on in-hospital mortality.

Methods: Adult blunt TBI patients with ICP monitoring between 2007 and 2017 were evaluated using sequential multivariable binary logistic modeling.

The public health burden of geriatric trauma: Analysis of 2,688,008 hospitalizations from Centers for Medicare and Medicaid Services inpatient claims.

Background: Geriatric trauma care (GTC) represents an increasing proportion of injury care, but associated public health research on outcomes and expenditures is limited. The purpose of this study was to describe GTC characteristics, location, diagnoses, and expenditures.

Methods: Patients at short-term nonfederal hospitals, 65 years or older, with ≥1 injury International Classification of Diseases, Tenth Revision, were selected from 2016 to 2019 Centers for Medicare and Medicaid Services Inpatient Standard Analytical Files.

Thromboelastography Utilization in Delayed Recurrent Coagulopathy after Severe Eastern Diamondback Rattlesnake Envenomation.

Venomous snakebites are fairly common in the United States and can present with a wide range of symptoms. A 48-year-old man presented after Eastern Diamondback rattlesnake envenomation. His hospital course was complicated by right leg compartment syndrome and delayed recurrent coagulopathy, requiring multiple doses of Crotalidae Polyvalent Immune Fab (CroFab) antivenom and transfusions.

What's in the Box? The Effectiveness of a Low-Volume Massive Transfusion Protocol.

Transfusion ratios approaching 1:1:1 of packed red blood cells (PRBCs) to fresh frozen plasma (FFP) to platelet have been shown to improve outcomes in trauma. There is little data available to describe in what quantity that ratio should be delivered. We hypothesized that lowering the total volume of products delivered in each protocol round would not adversely affect outcomes in the bleeding trauma patient.

Sugar-derived organogels as templates for structured, photoluminescent conjugated polymer-inorganic hybrid materials.

Co-assembly of an inorganic-organic hybrid material through the combination of supramolecular organogel self-assembly, phase partitioning of a conjugated polymer (CP) and transcription of an inorganic oxide leads to a hybrid material with structured domains of organogel, CP and silica within tube and rod microstructures.

Improved survival of patients with pseudomyxoma peritonei receiving intraperitoneal chemotherapy with cytoreductive surgery: a systematic review and meta-analysis.

Background: Pseudomyxoma peritonei (PMP) is an uncommon but lethal variant of adenocarcinoma. Many recent case series have reported improved survival with the combination of cytoreductive surgery and intraperitoneal chemotherapy (IPEC) in treating PMP. The aim of this study was to analyze the published studies for improved survival with this treatment strategy.

Sea urchin embryos exposed to thalidomide during early cleavage exhibit abnormal morphogenesis later in development.

Background: Clinical use of thalidomide has increased drastically, pushing the questions concerning the teratogenic mechanisms of this drug back to the forefront. Progress in understanding the teratogenic mechanisms has been slow, with the lack of non-primate vertebrate animal models susceptible to the classic reduction deformities remaining a concern. Sea urchin embryos have been used as model organisms for developmental studies for the last century.

Chemical composition of seminal and ovarian fluids of chinook salmon (Oncorhynchus tshawytscha) and their effects on sperm motility traits.

The relationships between the compositions of ovarian, seminal fluids and sperm function are not well known in teleostean fish species. The objective of the present study was to determine the concentration of the major inorganic ions (Na(+), K(+), Ca(2+), Mg, Cl(-)), osmolality, and pH of ovarian and seminal fluid of sexually mature chinook salmon (Oncorhynchus tshawytscha), and to determine if the composition of these fluids influences sperm motility traits (swimming speed, duration of forward mobility, swimming path trajectory, and percent motility). Cation concentrations and osmolality were significantly different in the two fluids.

Perceived barriers to health care access in a treated population.

Objective: Health care access may be a significant contributor to health outcome. However, few data exist on perception of barriers by patients in treatment, and attending a clinic visit does not mean that no barriers exist. Understanding barriers for treated populations is particularly important in optimizing care for high vulnerability populations, such as those with mental illness and the elderly.
