Facial fractures make up a significant proportion of injuries in trauma patients (1, 2). Approximately 3 million individuals suffer craniofacial trauma in the United States on a yearly basis, and approximately 50% of all wounds presenting to emergency rooms involve the head and neck (1, 2). Treatment of these fractures often results in standard surgical interventions. While up to the early 1980's perioperative antibiotic prophylaxis in maxillofacial surgery was controversial, its efficacy is well accepted today (3). Previous research work showed that the administration of antibiotics one hour preoperatively and eight hours after the intervention reduces the incidence of infectious complications in facial fractures from 42.2% to 8.9% (4). However there is still no consensus about the duration of the postoperative administration. In literature postoperative prophylaxis in facial fractures varies from single-shot up to duration of 7 and even ten days postoperatively. The use of antibiotics can be associated with allergic or toxic reactions, adverse effects, drug interactions and increasing bacterial resistance (5). In addition some authors assume that a prolonged administration of antibiotics might increase the risk of infectious complications via superinfection. On the other hand a short term or single shot administration might not be enough to prevent the onset of a postoperative infection. Up to date there is no standard to support the duration of antibiotic administration after surgical repair of a facial fracture. In this proposal, Investigators are aiming to investigate if either the utility of antibiotics administered for 3 days or 5 days make a difference in the clinical outcomes after facial fractures.

The objective of this study is to compare open and minimally invasive pancreatic and liver resection techniques and analyze the different outcome variables from the clinical standpoint. The plan is to investigate patient survival, length of stay, complication rates, operative time, transfusion rate, 30 and 90-day readmission rate, and hospital charges. Read Less

Primary Objective(s) To collect clinical data related to the treatment outcomes of Pancreatic IRE in order to develop an evidence base such that physicians can provide the best possible care to patients with pancreatic cancer requiring surgical intervention. Secondary Objective(s) To collect data on adverse events and complications related to IRE treatment. The AHPBA (Americas Hepato-Pancreato-Biliary Association) will be responsible for data collection and will periodically audit the data for quality assurance purposes. The AHPBA will review outcomes reported by each participating Research Institution and if outcomes are in the lower percentile, the investigators will be offered support to analyze the reasons for the suboptimal outcomes and may seek support to improve outcomes. The participating Research Institutions will receive a certificate annually that acknowledges their participation in the Research Project. Read Less

The prevalence of obesity has tripled in the last 50 years with presently about 1.7 billion of the world population aged 18 years and over either overweight or obese.1 In the US alone, 35% of the population is obese.2 Although alternative surgical approaches are available, bariatric surgery results in substantial and durable weight reduction for the majority of patients, making it the most effective treatment for severe obesity.3 In the battle to reduce the invasiveness of bariatric procedures, laparoscopy has become the gold standard approach for virtually all bariatric surgery procedures in the years since it was first used for gastric bypass by Wittgrove and colleagues in 1993.5 Available data shows perioperative patient-oriented advantages of laparoscopy when compared with open surgery, including a shorter hospital stay, decreased postoperative pain, and enhanced postoperative recovery.6 The Agency for Healthcare Research and Quality (AHRQ) reported significant improvements in the safety of metabolic/bariatric surgery due in large part to improved surgical techniques.7 The risk of death is about 0.1%8 and the overall likelihood of major complications is about 4%.9 Performing bariatric surgery laproscopically can be demanding in many situations because of large livers and substantial visceral fat that limit the working space and make exposure, dissection, and reconstruction difficult.10 Similarly, thick abdominal walls may cause excessive torque on instruments. Under such situations, surgeons' ergonomics become a serious concern.11 Use of robotics in bariatric surgery has been evolving since Cadiere and colleagues reported the first case in 1999.12 Robotic surgery has provided the surgeons with the advantage of three-dimensional vision as well as increased dexterity and precision by downscaling surgeon's movements enabling a fine tissue dissection and filtering out physiological tremor.13 It overcomes the restraint of torque on ports from thick abdominal wall, and minimizes port site trauma by remote center technology.14 Although Roux-en-Y gastric bypass (RYGB) is considered by many to be the gold standard procedure for weight loss,4 several studies demonstrate that sleeve gastrectomy (SG) and RYGB provide comparable weight loss.15 In fact, utilization of SG significantly increased from 9.3% in 2010 to 58.2% in 2014.16 Read Less

This is a prospective interventional trial with healthy volunteers at Methodist Dallas Medical Center. We anticipate data collection to be completed by December 2023. All study participants will be consented regardless of their role as healthy C-spine volunteer or provider volunteer (Appendix C). No compensation will be provided. Provider volunteers will be classified as: * Attending * Resident * Physician assistant, nurse practitioner, or nurse * EMS/Paramedic * Other, as determined by job functions in pre-assessment Read Less

This is a retrospective registry dataset of all adults who presented with cervical and/or skull base fractures or a subdural hematoma at Methodist Dallas Medical Center (MDMC) and had consults to the neurological surgery department beginning in January of 2016, and continuing until a statistically significant number of cases are obtained.

Retrospective chart review will be conducted on patients at Methodist Dallas Medical Center, meeting the inclusion criteria from January 1, 2019 to December 15, 2020 to determine the transplant free survival and overall survival and other secondary outcome measures. Read Less

The objective is to provide a mechanism to store information regarding the demographic characteristics; pre-, intra-, and post-transplant laboratories; treatment strategies; complications; and outcomes in patients undergoing hepatic transplantation. Read Less

This registry study will investigate the incidence of and outcomes associated with clopidogrel hyper-responsive patients treated at Methodist Dallas Medical Center, beginning in January 2018, who suffered cerebral aneurysms. Read Less

Determine the levels of Donor-derived (dd)cell-free DNA(cfDNA )in liver transplant recipients with normal liver function tests (LFTs) indicating stable immunosuppression status (IS). Based on this range use the dd-cfDNA levels to determine over or under IS in liver transplant patients to make changes to their IS medication regimen. Read Less

The purpose of this study is to evaluate the efficacy, safety, and adequacy of Endoscopic Ultrasound (EUS) Portal Pressure Gradient Measurement (PPGM) in patients undergoing EUS-guided liver biopsies. Read Less

The investigator's propose a multicenter prospective observational study to investigate the use of embolization in patients with negative angiogram and to ascertain the optimal level of treatment when the angiogram is positive; non-selective vs. selective embolization. Read Less
