Unhoused and Injured: Injury Characteristics and Outcomes in Unhoused Trauma Patients.

Introduction: The unhoused population is known to be at high risk for traumatic injury. However, there are scarce data regarding injury patterns and outcomes for this patient group. This study aims to investigate any differences in injury characteristics and hospital outcomes between unhoused and housed patients presenting with traumatic injuries.

Lack of Concordance Between Abbreviated Injury Scale and American Association for the Surgery of Trauma Organ Injury Scale in Patients with High-Grade Solid Organ Injury.

Background: The Abbreviated Injury Scale (AIS) is widely used for body region-specific injury severity. The American Association for the Surgery of Trauma Organ Injury Scale (AAST-OIS) provides organ-specific injury severity but is not included in trauma databases. Previous researchers have used AIS as a surrogate for OIS.

Back on the Streets: Examining Emergency Department Return Rates for Unhoused Patients Discharged After Trauma.

Background: The unhoused population is at high risk for traumatic injuries and faces unique challenges in accessing follow-up care. However, there is scarce data regarding differences in Emergency Department (ED) return rates and reasons for return between unhoused and housed patients.

Methods: We conducted a 3-year retrospective cohort study at a level-1 trauma center in a large metropolitan area.

Understanding the human conflict processing network: A review of the literature on direct neural recordings during performance of a modified stroop task.

The Stroop Task is a well-known neuropsychological task developed to investigate conflict processing in the human brain. Our group has utilized direct intracranial neural recordings in various brain regions during performance of a modified color-word Stroop Task to gain a mechanistic understanding of non-emotional human conflict processing. The purpose of this review article is to: 1) synthesize our own studies into a model of human conflict processing, 2) review the current literature on the Stroop Task and other conflict tasks to put our research in context, and 3) describe how these studies define a network in conflict processing.

Stereotactic Frame-Based Electrode Insertion: The Accuracy of Increasingly Oblique Insertion Angles.

Aim: To investigate the relationship between planned drill approach angle and angular deviation of the stereotactically placed intracranial electrode tips.

Material And Methods: Stereotactic electrode implantation was performed in 13 patients with drug resistant epilepsy. A total of 136 electrodes were included in our analysis.

Mitochondrial uncouplers impair human sperm motility without altering ATP content†.

In human spermatozoa, the electrochemical potentials across the mitochondrial and plasma membranes are related to sperm functionality and fertility, but the exact role of each potential has yet to be clarified. Impairing sperm mitochondrial function has been considered as an approach to creating male or unisex contraceptives, but it has yet to be shown whether this approach would ultimately block the ability of sperm to reach or fertilize an egg. To investigate whether the mitochondrial and plasma membrane potentials are necessary for sperm fertility, human sperm were treated with two small-molecule mitochondrial uncouplers (niclosamide ethanolamine and BAM15) that depolarize membranes by inducing passive proton flow, and evaluated the effects on a variety of sperm physiological processes.

A review of neurophysiological effects and efficiency of waveform parameters in deep brain stimulation.

Neurostimulation has diverse clinical applications and potential as a treatment for medically refractory movement disorders, epilepsy, and other neurological disorders. However, the parameters used to program electrodes-polarity, pulse width, amplitude, and frequency-and how they are adjusted have remained largely untouched since the 1970 s. This review summarizes the state-of-the-art in Deep Brain Stimulation (DBS) and highlights the need for further research to uncover the physiological mechanisms of neurostimulation.

Postoperative narcotic utilization in single incision laparoscopic-assisted extracorporeal appendectomy (SILEA): a single-institution retrospective review.

Purpose: Laparoscopic appendectomy for pediatric acute appendicitis is commonly performed by pediatric surgeons. A single incision approach has been investigated, but the lack of technical uniformity has resulted in conflicting data. We hypothesized that an initial single incision laparoscopic-assisted extracorporeal appendectomy (SILEA) approach is associated with similar complication rates as compared to the standard three-incision laparoscopic appendectomy (TILA).

Baseline hippocampal beta band power is lower in the presence of movement uncertainty.

This study aimed to characterize hippocampal neural signatures of uncertainty by measuring beta band power in the period prior to movement cue.. Participants with epilepsy were implanted with hippocampal depth electrodes for stereo electroencephalographic (SEEG) monitoring.
