Pcl And Pegdma Nanoyarns Feasibility For Antimicrobial Suture Applications, Wynn Bastianelli, Dominique Hassinger, Vincent Beachley, Sean Mcmillan

Rowan-Virtua Research Day

Abstract Title: PCL and PEGDMA Nanoyarns Feasibility for Antimicrobial Suture

Nanofibers represent an innovative class of materials with diverse applications, including tissue engineering and drug delivery.¹ Among the most promising areas of research is their use in surgical sutures, particularly for complex orthopedic injuries with high re-tear rates. Polycaprolactone (PCL) nanofibers have shown promise as alternatives to standard sutures as their unique properties support superior healing compared to standard materials.² Our lab aims to further optimize these healing capabilities by adding Poly(ethylene glycol) dimethacrylate (PEGDMA), a molecule that tethers peptides to PCL nanoyarns, developing a suture with greater …

Quantitative Fluorescence Imaging Using A Paired Agent Approach For Improving Surgical Decision Making, Sanjana Pannem

Dartmouth College Ph.D Dissertations

Surgical resection remains to be the cornerstone of treatment for most solid tumors, where the primary objective is to remove all visible and microscopic disease. However, the extent of tumor resection is inherently limited by the surgeon’s ability to distinguish tumor from normal tissue, intraoperatively. As a result, positive surgical margins (PSM), where residual tumor remains after surgery, are a common occurrence and are associated with increased recurrence, need for adjuvant therapies, dismal patient outcomes, and high healthcare costs.

Fluorescence guided surgery (FGS) has emerged as a promising technique to enhance intraoperative visualization of tumors and may help reduce the …

SKMC Student Presentations and Publications

OBJECTIVE: To investigate the impact of clinical surveillance, primary radiotherapy, and primary surgery on overall survival (OS) in laryngeal carcinoma in situ (Cis).

METHODS: The 2006-2020 National Cancer Database was queried for adults with a biopsy-proven diagnosis of laryngeal Cis. Multivariable binary logistic and Cox proportional hazards regression models were implemented.

RESULTS: Of 3567 unique patients satisfying inclusion criteria, 514 (14.4%) underwent clinical surveillance, 1074 (30.1%) underwent primary radiotherapy, and 1979 (55.5%) underwent primary surgery. Receiving treatment at an academic/research facility was associated with higher odds of undergoing primary surgery compared to primary radiotherapy. Among 646 patients undergoing primary surgery …

Rethinking Pain Relief After Surgery: What We Can Learn From Knee Replacements, Asim Trimzi

SKMC Student Presentations and Publications

This paper offers a clear, evidence-based look at how we can reduce opioid use after knee replacement surgery without sacrificing pain relief. This review focuses specifically on total knee arthroplasty (TKA)-one of the most commonly performed and most painful surgeries-and asks whether opioids are truly necessary. By analyzing results from 21 clinical trials, the paper shows that non-opioid medications like NSAIDs and gabapentinoids can provide similar pain control with fewer side effects, such as nausea, dizziness, constipation, and sedation. Lower risk of long-term use is an added benefit. A recent RCT found that after knee/shoulder arthroscopy, 72% of patients in …

External Jugular Vein Catheterization Technique For Continuous Blood Sampling In Gilts, Preechaphon Taechamaeteekul, Yosua Kristian Adi, Chutikan Srisang, Pirada Virankabutra, Natchanon Dumniem, Jinda Singlor, Padet Tummaruk

The Thai Journal of Veterinary Medicine

External jugular vein blood collection is common in gilts and sows, but continuous sampling for hormonal and pharmacokinetic research requires catheterization. The standard protocol has remained largely unchanged for nearly 40 years. This study aimed to develop a modified external jugular vein catheterization technique in gilts. Ten gilts (72.0 ± 3.4 kg) underwent surgery under general anesthesia after 12-hour fasting. Sedation was induced with intramuscular Xylazine (4.4 mg/kg) and Tiletamine–Zolazepam (2.2 mg/kg), followed by intravenous Thiopental sodium (10 mg/kg). Once anesthetized, gilts were placed in dorsal recumbency, and the external jugular fossa was prepared under sterile conditions. A 10 cm …

Improving Awareness And Identifying Risks For Emergence Delirium In Military Veterans, Hannah E. Pino

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: Emergence delirium (ED) is an acute state of confusion during the recovery phase from anesthesia that may be life-threatening, especially in the veteran population. Military veteran status may be explored by the Have You Ever Served questionnaire that was developed by the American Academy of Nursing to identify veterans upon admission to the hospital and thus be able to better care for them during their stay. This campaign has been in effect at the hospital site of this project for nearly 10 years. The questionnaire identifies military history risk factors such as combat history or a diagnosis of post-traumatic …

Systematic Review Of Needlestick Injuries In The Operating Room: A Case For Surgical Glove Redesigning, Shalmali Mirajkar, Zachary Bauman, Bethany Lowndes

EMET Projects

Background: Sharps or needlestick injuries (NSI) occur in roughly 15% of surgeries and are largely preventable. With such injuries, healthcare workers have a high risk of exposure to blood borne pathogens. Despite the implementation of several prevention measures such as double gloving and using blunt suture needles, there is still a high prevalence of NSIs. The aim of the current study is to conduct a systematic review to identify the most vulnerable parts of the hand for needlestick injuries, the most common tasks during which injuries occurred, and the most common instrument associated with the injury.

Methods: A …

Journal of Patient-Centered Research and Reviews

Purpose: This study aimed to determine if standardized updates at specific perioperative events affect anxiety and satisfaction of the family members and if the length of surgical procedure affects the satisfaction with updates.

Methods: This study was a randomized control trial. In the control group, surgeons communicated with the family only once near the completion of the procedure. In the intervention group, families received electronic updates at 3 significant perioperative events during the procedure. A postoperative survey rating family member satisfaction and anxiety levels, using a Likert scale of 0–5, was administered.

Results: Mean level of overall satisfaction did not …

Surgeons’ Views On Shared Decision-Making, Suraj Kannan, Jayhyun Seo, Kevin R. Riggs, Gail Geller, Emily F. Boss, Zackary D. Berger

Journal of Patient-Centered Research and Reviews

Purpose: Shared decision-making (SDM) has a significant role in surgical encounters, where decisions are influenced by both clinician and patient preferences. Herein, we sought to explore surgeons’ practices and beliefs about SDM.

Methods: We performed a qualitative study consisting of semi-structured individual interviews with 18 surgeons from private practice and academic surgery practices in Baltimore, Maryland. We purposively sampled participants to maximize diversity of practice type (academic vs private), surgical specialty, gender, and experience level. Interview topics included benefits and challenges to patient involvement in decision-making, communicating uncertainty to patients, and use of decision aids. Interviews were audio-recorded and transcribed. …

Innovative Care Of Individuals In The Athletic Training Room: A Case Series, Kathryn E. Young

Senior Honors Projects, 2010-2019

This work follows three unique cases of athletic injuries and/or injuries in patients. These cases were selected because of the innovative nature of the rehabilitation process conducted by the sports medicine team via the athletic training room or the unique nature of the injury/case.

The first is a concussion sustained from a motor vehicle accident in a collegiate female thrower. This is unique because it’s a non-sport related concussion handled as an athletic trainer would handle a sports related concussion. It also demonstrates a new unique protocol for concussion management.

The second case is a patient with two complete anterior …

Effects Of Revision Surgery On Grade Of Adverse Local Tissue Reaction Following Recall Of A Modular Hip Implant, Joseph F. Davies, Danielle M. Greer, Susan Truchan

Journal of Patient-Centered Research and Reviews

Background: The Stryker Rejuvenate modular hip implant device allows for greater versatility in matching a patient’s anatomy than conventional implants. Device recalls and in vivo metal hypersensitivity after total hip arthroplasty (THA) are common. However, recall of the Rejuvenate implant represents one of the largest recall volumes to date, highlighting our uncertainty regarding causes of device metal fretting/corrosion and adverse local tissue reaction (ALTR). While devices with metal-on-metal bearings historically were culprits for release of metal debris, more recently developed modular-neck devices add opportunity for adjacent metal components to rub together. With the Rejuvenate device, corrosion or fretting likely occurs …

Laparoscopic Harvest Of The Rectus Abdominis For Perineal Reconstruction, Nneamaka Agochukwu, Alisha Bonaroti, Sandra Beck, James Liau

Surgery Faculty Publications

The rectus abdominis is a workhorse flap for perineal reconstruction, in particular after abdominoperineal resection (APR). Laparoscopic and robotic techniques for abdominoperineal surgery are becoming more common. The open harvest of the rectus abdominis negates the advantages of these minimally invasive approaches. (Sentence relating to advantages of laparoscopic rectus deleted here.) We present our early experience with laparoscopic harvest of the rectus muscle for perineal reconstruction. Three laparoscopic unilateral rectus abdominis muscle harvests were performed for perineal reconstruction following minimally invasive colorectal and urological procedures. The 2 patients who underwent APR also had planned external perineal skin reconstruction with local …

Re-Tubularization Of Highly-Ischemic Anti-Mesenteric Border (Rehab): A Novel Bowel Preservation Technique In Complex Gastroschisis., Richard J. Hendrickson, Ashwini S. Poola, Katherine W. Gonzalez, Joel Lim, Tolulope A. Oyetunji

Manuscripts, Articles, Book Chapters and Other Papers

Complex gastroschisis with bowel necrosis poses an operative challenge. Surgeons must weigh the decision between resection versus preservation of ischemic bowel. As one of the leading causes of short bowel syndrome, aggressive resection in complicated gastroschisis subjects children to prolonged dependence on parenteral nutrition and its attendant complications. Herein, we describe a novel technique aimed towards bowel preservation in complex gastroschisis patients with severe bowel ischemia with the ultimate goal for enteral autonomy.

Choosing An Allograft Or Autograft In Orthopedic Surgeries For Athletes, Cassandra M. Izzo

Honors Theses and Capstones

Athletes and their doctors have the choice of using an allograft or autograft in reconstruction surgeries. The purpose of this study is to see if there is a difference in the healing mechanism and surgical outcome in using an allograft or autograft during orthopedic surgical procedures, as well as to analyze graft rejection and disease transmission through donor tissue.

Doctors and athletic trainers were interviewed in order to learn about the healing mechanisms and advantages and disadvantages of allografts and autografts in order to conclude if one was better than the other. College level athletes on different sports teams were …

BACKGROUND: Compared with elective surgical procedures, emergency procedures are associated with higher cost, morbidity, and mortality. This study seeks to investigate potential state-by-state variations in the incidence of emergent versus elective colon resections.

METHODS: A retrospective analysis of all adult patients (aged ≥18 years) included in the Nationwide Inpatient Sample from 2005 to 2009 who underwent hemicolectomy (right or left) or sigmoidectomy was conducted. Discharge-level weights were applied, and generalized linear models were used to assess the odds of a patient undergoing emergent versus elective colon surgery nationally and for each state after adjusting for patient and hospital factors. Odds …

Open Versus Laparoscopic Hiatal Hernia Repair., Terrence M. Fullum, Tolulope A. Oyetunji, Gezzer Ortega, Daniel D. Tran, Ian M. Woods, Olusola Obayomi-Davies, Orighomisan Pessu, Stephanie R. Downing, Edward E. Cornwell

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: The literature reports the efficacy of the laparoscopic approach to paraesophageal hiatal hernia repair. However, its adoption as the preferred surgical approach and the risks associated with paraesophageal hiatal hernia repair have not been reviewed in a large database.

METHOD: The Nationwide Inpatient Sample dataset was queried from 1998 to 2005 for patients who underwent repair of a complicated (the entire stomach moves into the chest cavity) versus uncomplicated (only the upper part of the stomach protrudes into the chest) paraesophageal hiatal hernia via the laparoscopic, open abdominal, or open thoracic approach. A multivariate analysis was performed controlling for …
