Background: Cirrhosis causes significant coagulopathy. Traditional coagulation tests may not accurately measure coagulopathy in well-compensated patients with cirrhosis. Viscoelastic tests are functional tests that may better assess coagulopathy in cirrhotic patients.

Purpose: In New Jersey, politicians have emphasized the need to attenuate the ongoing opioid epidemic as opioid use disorder can lead to addiction and, in many cases, mortality. New legislation (New Jersey Senate Bill 3) was enacted in 2017 to reduce opioid prescription from 30 days to 5 days for acute pain in both inpatient and outpatient healthcare settings. Therefore, we sought to evaluate if the enactment of the bill influenced the consumption of opioid pain medication at an American College of Surgeons-verified Level I Trauma Center.

Introduction: Thromboelastography (TEG) is a functional test of coagulation used to guide transfusions. Despite literature supporting its utility, its use remains limited to select populations. In patients with cirrhosis, conventional coagulation tests are notoriously inaccurate, and TEG may be a better measure of coagulopathy.

Background: Previous studies have shown that dexmedetomidine (DEX) may be associated with reduced vasopressor requirements in septic shock patients, however, long-term DEX-only sedation in reducing vasopressor requirements is still controversial.

Methods: A retrospective study was conducted among patients with septic shock on mechanical ventilation using the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. The primary outcome was the ratio of norepinephrine equivalent dose to mean arterial pressure (NEq/MAP) in the first 72 h after DEX or other sedatives for sedation.

Objectives: Thyroidectomies involve meticulous dissection of a highly vascularized organ and complications may develop, such as hematoma, hypocalcemia, and even hypoparathyroidism. Because some of these complications may be fatal, we sought to identify the differences in postthyroidectomy outcomes when the use of a vessel sealant device (VSD) such, as LigaSure or Harmonic scalpel, is compared with more traditional techniques, such as ligatures and clips.

Methods: Using the 2016 American College of Surgeons National Surgical Quality Improvement Program Targeted Thyroidectomy database, we compared patients who underwent a thyroidectomy using a VSD with patients without a VSD for differences in postoperative complications.

Background: Literature suggests that unhealthy body mass index is a risk factor for adverse clinical outcomes.

Objectives: To study the association between unhealthy body mass index and morbidity and mortality after trauma using the 2016 American College of Surgeons Trauma Quality Improvement Program database.

Methods: A retrospective review was conducted comparing the normal weight control group to the underweight, overweight, obese, severely obese, and morbidly obese groups for differences in demographic factors, injury severity score, comorbidities, length of stay, and complications.

Introduction The removal of the terminal ileum may interfere with gut-associated lymphoid tissue function, reduce bile salt reabsorption, and change intraluminal pH, which may contribute to the development of infection (CDI) after ileocolic resections. Therefore, we compared CDI incidence among patients who underwent a colectomy with or without removal of the terminal ileum. Methods Using the 2016 American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Targeted Colectomy database, we identified 17,962 patients who underwent a left-sided colectomy without removal of the terminal ileum and 5,929 patients who underwent an ileocolic resection involving the removal of the terminal ileum.

Introduction: In trauma care, pelvic fractures contribute to morbidity and mortality. Since men and women have different pelvic structures and hormonal milieu, we studied if these gender differences affect clinical outcomes after pelvic fractures.

Methods: Using the 2016 American College of Surgeons Trauma Quality Improvement Program (ACS TQIP) database, we stratified 24,425 patients with pelvic fractures by gender.

Purpose: Femur fractures are the result of high energy injury and are associated with life-threatening complications. Therefore, we studied how body mass index (BMI) contributes to complications after femoral fractures.

Methods: Using the 2016 American College of Surgeons Trauma Quality Improvement Program (ACS TQIP) database, we stratified 41,362 patients into groups based on their BMI: Normal Weight (NW), Overweight (OW), Obese (OB), Severely Obese (SO), and Morbidly Obese (MO).

We present a case of a 60-year-old woman with chronic lower abdominal pain and green urine. Further workup revealed a cholecystovesicular fistula (CVF), a newly coined term to indicate a fistula between the gallbladder and the urinary bladder. The CVF was treated surgically.

Introduction: Efficient patient transportation by ground emergency medical services (GEMS) or helicopter emergency medical services (HEMS) to a trauma center is vital for optimal care. We investigated differences between the modes of transport in terms of demographics, injury, scene location, and outcome.

Setting: Morristown Medical Center (MMC), Morristown, NJ METHODS: All 903 trauma admissions in 2016 by advanced life support (ALS) to MMC, a Level I Trauma Center, were retrospectively analyzed.

Background: A retrospective analysis of all women undergoing hysterectomy at Sydney West Advanced Pelvic Surgery Unit (SWAPS) was performed in the nine-year period from 2001 to 2009.

Aims: To evaluate the incidence, timing and presenting symptoms of vaginal vault dehiscence after hysterectomy, especially via the laparoscopic approach to gain further understanding of patient risk factors and surgical factors that may predispose to this complication.

Methods: Women who presented with vaginal vault dehiscence were identified and possible pre-operative, intra-operative and post-operative risk factors were assessed.

Fenton and photoassisted Fenton degradation of ordinary hydrophobic cross-linked polystyrene microspheres and sulfonated polystyrene beads (DOWEX 50WX8) have been attempted. While the Fenton process was not able to degrade these polystyrene materials, photoassisted Fenton reaction (mediated by broad-band UV irradiation from a 250 W Hg(Xe) light source) was found to be efficient in mineralizing cross-linked sulfonated polystyrene materials. The optimal loadings of the Fe(III) catalyst and the H(2)O(2) oxidant for such a photoassisted Fenton degradation were found to be 42 μmol-Fe(III) and 14.
