Robotic Surgery in Safety-Net Hospitals: Addressing Health Disparities and Improving Access to Care.

Minimally invasive surgery (MIS) has demonstrated significant clinical and economic benefits that have been consistently validated and reproduced in practice and the literature for the past few decades. These benefits include improved patient outcomes, reduced complications, shorter hospital stays, decreased narcotic use, quicker recovery times, and lower rates of wound infections. However, safety-net hospitals, which historically serve a larger percentage of underserved and marginalized populations, often lack the resources to invest in high capital equipment.

Dispersal distances from splash-cup plants depend on the cup's angle and contents.

Splash-cup plants disperse propagules via raindrops striking cup-shaped fruiting bodies. The seeds are ejected at velocities up to five times the impact speed of the raindrop and are dispersed up to 1 m from the parent plant. Here, we examine the effects of cup angles and the presence of seed mimics to understand the dynamics of this unique method of dispersal.

Decreased readmission rates following use of modified trauma-specific frailty index in older trauma patients: A follow-up study.

Introduction: Post-discharge readmission rates using modified Trauma-Specific Frailty Index (mTSFI) compared to the Emergency Severity Index (ESI) are unknown. In our pilot study, we demonstrated that mTSFI usage more accurately triages older trauma patients. In the current study, we hypothesized that adult trauma patients triaged using mTSFI would have lower readmission rates at the 30-day interval post discharge.

A Comparative Analysis of Hospital Triage Systems in the Geriatric Adult Trauma Patients: A Quality Improvement Pilot Study.

Background: The objective of our study is to compare the predicted hospital admission disposition based on the level of risk as determined by the modified Trauma-Specific Frailty Index (mTSFI) score with those determined by arbitrary decisions made based on the Emergency Severity Index (ESI) severity level.

Methods: We surveyed 100 trauma patients ages 50 and older, admitted to a level 1 trauma center between April 2019 and July 2019. We retrospectively reviewed the hospital admission disposition of each patient under the ESI, which was then compared to the mTSFI-predicted hospital admission disposition.

Early versus late tube feeding initiation after PEG tube placement: Does time to feeding matter?

Background: Variation exists in the timing of tube feed initiation after percutaneous endoscopic gastrostomy (PEG) tube placement. The aim of our study was to review outcomes of early tube feed (ETF) versus late tube feed (LTF) initiation after PEG tube placement.

Methods: We performed a retrospective review of all trauma patients who underwent PEG tube placement from 1/2014 to 12/2018.

Primary prevention of contact sports-related concussions in amateur athletes: a systematic review from the Eastern Association for the Surgery of Trauma.

Background: Awareness of the magnitude of contact sports-related concussions has risen exponentially in recent years. Our objective is to conduct a prospectively registered systematic review of the scientific evidence regarding interventions to prevent contact sports-related concussions.

Methods: Using the Grading of Recommendations Assessment, Development, and Evaluation methodology, we performed a systematic review of the literature to answer seven population, intervention, comparator, and outcomes (PICO) questions regarding concussion education, head protective equipment, rules prohibiting high-risk activity and neck strengthening exercise for prevention of contact sports-related concussion in pediatric and adult amateur athletes.

"Black Esophagus" and Gastric Volvulus Following Slipped Laparoscopic Adjustable Gastric Band.

To review the entity "black esophagus" and sequela of a slipped laparoscopic adjustable band. The patient's history, physical examination, imaging, and endoscopic findings were reviewed. Detailed review of pathophysiology, presentation, diagnosis, management, and natural history was conducted.

Successful treatment of massive hemothorax with class IV shock using aortography with transcatheter embolization of actively bleeding posterior left intercostal arteries after penetrating left chest trauma: A case for the hybrid OR.

Unlabelled: Hemothorax is a common occurrence after blunt or penetrating injury to the chest. Posterior intercostal vessel hemorrhage as a cause of major intrathoracic bleeding is an infrequent source of massive bleeding. Selective angiography with trans-catheter embolization may provide a minimally invasive and efficient method of controlling bleeding refractory to surgical treatment.

Physiologically-based, predictive analytics using the heart-rate-to-Systolic-Ratio significantly improves the timeliness and accuracy of sepsis prediction compared to SIRS.

Background: Enhancing the efficiency of diagnosis and treatment of severe sepsis by using physiologically-based, predictive analytical strategies has not been fully explored. We hypothesize assessment of heart-rate-to-systolic-ratio significantly increases the timeliness and accuracy of sepsis prediction after emergency department (ED) presentation.

Methods: We evaluated the records of 53,313 ED patients from a large, urban teaching hospital between January and June 2015.

Hospital-based, Multidisciplinary, youth mentoring and medical exposure program positively influences and reinforces health care career choice: "The Reach One Each One Program early Experience".

Background: According to the National Center for Educational Statistics, underrepresented minorities (URMs) are more likely to leave science, technology, engineering and mathematics (STEM) fields at higher rates than their peers during undergraduate studies. Many institutions of higher learning have implemented pipeline programs aimed at preparing and inspiring high school and college aged students in select careers in health sciences with varying levels of success. Research has shown that a health care workforce that mirrors the community they serve is more effective in reducing health disparities and increasing positive health outcomes.

Vitamin D3 Suppresses Class II Invariant Chain Peptide Expression on Activated B-Lymphocytes: A Plausible Mechanism for Downregulation of Acute Inflammatory Conditions.

Class II invariant chain peptide (CLIP) expression has been demonstrated to play a pivotal role in the regulation of B cell function after nonspecific polyclonal expansion. Several studies have shown vitamin D3 helps regulate the immune response. We hypothesized that activated vitamin D3 suppresses CLIP expression on activated B-cells after nonspecific activation or priming of C57BL/6 mice with CpG.

Klebsiella pneumoniae Liver Abscess and Metastatic Endophthalmitis.

Introduction. Klebsiella pneumoniae is a well-known cause of liver abscess. Higher rates of liver abscess associated with Klebsiella pneumoniae are seen in Taiwan.

Epithelial ovarian cancer: An overview.

Ovarian cancer is the second most common gynecological cancer and the leading cause of death in the United States. In this article we review the diagnosis and current management of epithelial ovarian cancer which accounts for over 95 percent of the ovarian malignancies. We will present various theories about the potential origin of ovarian malignancies.

Using augmented reality as a clinical support tool to assist combat medics in the treatment of tension pneumothoraces.

This study was to extrapolate potential roles of augmented reality goggles as a clinical support tool assisting in the reduction of preventable causes of death on the battlefield. Our pilot study was designed to improve medic performance in accurately placing a large bore catheter to release tension pneumothorax (prehospital setting) while using augmented reality goggles. Thirty-four preclinical medical students recruited from Morehouse School of Medicine performed needle decompressions on human cadaver models after hearing a brief training lecture on tension pneumothorax management.

The effect of video game "warm-up" on performance of laparoscopic surgery tasks.

Background: Performing laparoscopic procedures requires special training and has been documented as a significant source of surgical errors. "Warming up" before performing a task has been shown to enhance performance. This study investigates whether surgeons benefit from "warming up" using select video games immediately before performing laparoscopic partial tasks and clinical tasks.

Benefit of a Tiered-Trauma Activation System to Triage Dead-on-Arrival Patients.

Introduction: Although national guidelines have been published for the management of critically injured traumatic cardiopulmonary arrest (TCPA) patients, many hospital systems have not implemented in-hospital triage guidelines. The objective of this study was to determine if hospital resources could be preserved by implementation of an in-hospital tiered triage system for patients in TCPA with prolonged resuscitation who would likely be declared dead on arrival (DOA).

Method: We conducted a retrospective analysis of 4,618 severely injured patients, admitted to our Level I trauma center from December 2000 to December 2008 for evaluation.
