Primum Non Nocere: Surgeons And The Politics Of Firearm Trauma, Kaushal Desai

Gibbon Surgical Review

The crisis of firearm violence in America continues to worsen and the call to action cannot be ignored. If we are to make a real impact, we must be just as skilled policy makers as proceduralists. We must wield the pen as well as we wield the scalpel. All the clinical knowledge and surgical skills in the world will make no difference if we do not reduce the number of firearm injuries. The skillset we need is policy analysis and lobbying, which can only be developed through political activism and engagement, not more practice questions and Online MedEd.

General Surgery 101: Nissen Fundoplication, Kelley Yuan, Tyler Bauer

Gibbon Surgical Review

The first time that medical students enter the OR can be a jarring experience. Successfully maintaining sterility is hard enough, but remembering relevant patient history, answering “pimp” questions, and performing basic suturing skills can make the third year medical student experience difficult. In this article we describe a common surgery performed by both general and thoracic surgeons with a specific focus on “medical student level” understanding. This piece is the product of a collaboration between an MS1 and MS4, both of whom are interested in a career in surgery. We hope you find it helpful!

Interview With Dr. Dawn Salvatore, Preeyal Patel

Gibbon Surgical Review

A medical student’s path to surgery is notoriously long and arduous. Traditionally, students who are interested in the field begin to prepare their qualifications from day one, especially given the competitive nature of acceptance into surgical programs. For students who develop an interest in surgery during their later years of medical school, it can be a daunting task to pursue a track in which they already feel behind. Often times, these students are discouraged from applying to surgical residencies, worrying that their non-traditional path may hinder their success. However, Dr. Dawn Salvatore can reassure students that a non-traditional path to …

The Utility Of Surgical Simulation In Student Education, Jared Raikin

Gibbon Surgical Review

The use of simulation in the field of surgery has become a heavily researched topic over the last few decades, but it is by no means a new concept. The first recorded use of surgical simulation dates back 2,500 years with evidence of nasal models for flap reconstruction made of leaf and clay.1 But simulation as we know it today did not take shape until the 1980s with the invention of the Comprehensive Anesthesia Simulation Environment (CASE) mannequins. The use of nonorganic simulation tools revolutionized the field and continues to play a large role in medical education. These modalities have …

Bedside To Bench: Basic Science Research During General Surgery Residency, Signe Caksa

Gibbon Surgical Review

Clinical, basic science, and quality improvement research is becoming increasingly integrated into general surgery residency programs, providing aspiring surgeons with an avenue to engage with academia and improve patient care early on in their careers. For example, as an essential part of their training, general surgery residents at Thomas Jefferson University Hospital (TJUH) complete one to two years of research, usually between their PGY3 and PGY4 years. The goal of this protected research time is for residents to gain hands-on surgical research skills and work on translational research projects that correlate with clinical cases, while also becoming more competitive for …

Longevity In Surgery: A Conversation With Two Temple Surgeons About How They Continually Find Joy In Their Careers, Kelsey Muir

Gibbon Surgical Review

Both Dr. Daly and Dr. Pontari describe the stress and pressure that comes with a long career in patient care, however intertwined with the stress is their overwhelming gratitude and joy for surgery. Maintaining that perspective for medicine and patient care has required two things: community and an outlet. Dr. Daly and Dr. Pontari expressed the need to be able to share their anxieties and struggles with someone to process the stress, the difficulties, and the demands of a surgical career.

Surgery Myths And Facts, Heli Patel

Gibbon Surgical Review

Throughout social media, television shows, movies, and “public perception”, surgical residents and attendings are often stereotyped into a personality that is most often incorrect. Unless you are a surgeon, it is often hard to understand what exactly the life entails. Add in some Hollywood drama and social media, and what you get is a wildly disproportionate picture of what surgeons’ personalities are like. As a medical student, it is often difficult to separate fact from fiction, so here are some of the most common myths debunked.

John H. Gibbon, Jr., Md

Gibbon Surgical Review

Dr. John Heysham Gibbon, Jr. graduated from Jefferson Medical College in 1927, and in a brief series of events, he was named Fellow at Massachusetts General Hospital. In 1930, he found himself assisting Dr. Edward Churchill in an emergency pulmonary embolectomy. At that time the procedure was one of desperation, as no patient in the U.S. had survived the removal of blood clots in open-heart surgery. As Dr. Gibbon recorded the patient’s waning vital signs prior to the procedure he thought, “If only we could remove the blood from her body by bypassing her lungs, and oxygenate it, then return …

Anesthesia For The Patient With A Recently Diagnosed Concussion: Think About The Brain!, Mohammed R. Rasouli, Michelle Kavin, Stephen Stache, Michael E. Mahla, Eric S. Schwenk

Department of Anesthesiology Faculty Papers

Some patients require emergent, urgent, or elective surgery in the time period immediately following diagnosis of concussion. However, changes in brain homeostatic mechanisms following a concussion and concern for secondary brain injury can complicate the decision as to whether or not a surgery should proceed or be postponed. Given the paucity of available evidence, further evaluation of the use of anesthesia in a patient with concussion is warranted. This article summarizes what is currently known about the relevant pathophysiology of concussion, intraoperative anesthesia considerations, and effects of anesthesia on concussion outcomes in an attempt to help providers understand the risks …

Ultra-Fast Conductive Media For Rna Electrophoretic Mobility Shift Assays., Samantha Z Brown, Lebaron C Agostini, Henry L Thomsett, Jonathan R Brody

Department of Surgery Faculty Papers

The use of RNA electrophoretic mobility shift assays (REMSAs) for analysis of RNA-protein interactions have been limited to lengthy assay time and qualitative assessment. To vastly improve assay efficiency, feasibility and quality of data procured from REMSAs, we combine here some of the best-known labeling and electrophoretic techniques. Nucleic acid fragments are end-labeled with fluorescent tags, as opposed to the radioactive or biotin tags. The fluorescent probes may be detected directly from the electrophoresis gel, eliminating the need for cumbersome membrane transfer and immunoblotting. Modifying the REMSA protocol to include low-molarity, lithium borate conductive media and near-infrared-labeled probes allows for …

Objectives: Cervical pseudarthrosis is a frequent cause of need for revision anterior cervical discectomy and fusion (ACDF) and may lead to worse patient-reported outcomes. The effect of proton pump inhibitors on cervical fusion rates are unknown. The purpose of this study was to determine if patients taking PPIs have higher rates of nonunion after ACDF.

Methods: A retrospective cohort review was performed to compare patients who were taking PPIs preoperatively with those not taking PPIs prior to ACDF. Patients younger than 18 years of age, those with less than 1-year follow-up, and those undergoing surgery …

Contemporary Nstemi Management: The Role Of The Hospitalist., Charles V Pollack, Alpesh Amin, Tracy Wang, Steven Deitelzweig, Marc Cohen, David Slattery, John Fanikos, Christopher Dilascia, Regan Tuder, Scott Kaatz

Department of Emergency Medicine Faculty Papers

Non-ST-segment elevation myocardial infarction (NSTEMI) is defined as elevated cardiac biomarkers of necrosis in the absence of persistent ST-segment elevation in the setting of anginal symptoms or other acute event. It carries a poorer prognosis than most ST-segment elevation events, owing to the typical comorbidity burden of the older NSTEMI patients as well as diverse etiologies that add complexity to therapeutic decision-making. It may result from an acute atherothrombotic event ('Type 1') or as the result of other causes of mismatch of myocardial oxygen supply and demand ('Type 2'). Regardless of type and other clinical factors, the hospital medicine specialist …

Acoustic Parameters For Optimal Ultrasound-Triggered Release From Novel Spinal Hardware Devices., Lauren J. Delaney, Cemile Basgul, Daniel W Macdonald, Keith Fitzgerald, Noreen J. Hickok, Steven M Kurtz, Flemming Forsberg

Department of Radiology Faculty Papers

Post-operative infection is a catastrophic complication of spinal fusion surgery, with rates as high as 10%, and existing preventative measures (i.e., peri-operative antibiotics) are only partially successful. To combat this clinical problem, we have designed a drug delivery system around polyether ether ketone clips to be used for prophylactic post-surgical release of antibiotics upon application of ultrasound. The overall hypothesis is that antimicrobial release from this system will aggressively combat post-surgical bacterial survival. This study investigated a set of acoustic parameters optimized for in vitro ultrasound-triggered coating rupture and subsequent release of encapsulated prophylactic antibiotics. We determined that a transducer …

Linkage Between Poverty And Smoking In Philadelphia And Its Impact On Future Directions For Tobacco Control In The City., Christine S. Shusted, Gregory C. Kane

Department of Medicine Faculty Papers

Poverty is linked to negative health consequences and harmful health behaviors such as smoking. Despite this established correlation, few comparative studies have investigated the relationship between local poverty rates and smoking in urban settings through a Social Ecological Model framework. The authors sought to examine the linkage between local poverty rates in Philadelphia, Pennsylvania and adult smoking rates by scrutinizing existing patterns and potential mediating factors via publicly accessible data in established planning districts. The authors determined several individual, interpersonal, organizational, community, and environmental factors, varying across these districts, that impact smoking in Philadelphia. Poverty rates influence the resources, demographic …

Abington Jefferson Health Posters

Angioimmunoblastic T cell lymphoma(AITL) is one of the rarest T cell lymphomas. Diagnosing the type of lymphoma is crucial, as the management differs depending on the type. We present a case of a sixty-one-year-old woman who presented with generalized lymphadenopathy and how we unfolded the diagnosis.

Evaluation Of The Effect Of Gm-Csf Blocking On The Phenotype And Function Of Human Monocytes, Noushin Lotfi, Guang-Xian Zhang, Nafiseh Esmaeil, Mohamad Rostami

Department of Neurology Faculty Papers

Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a multipotent cytokine that prompts the proliferation of bone marrow-derived macrophages and granulocytes. In addition to its effects as a growth factor, GM-CSF plays an important role in chronic inflammatory autoimmune diseases such as multiple sclerosis and rheumatoid arthritis. Reports have identified monocytes as the primary target of GM-CSF; however, its effect on monocyte activation has been under-estimated. Here, using flow cytometry and ELISA we show that GM-CSF induces an inflammatory profile in human monocytes, which includes an upregulated expression of HLA-DR and CD86 molecules and increased production of TNF-α and IL-1β. Conversely, blockage of …

Global Health Articles

South Asia has >50% of the global burden of low birth weight (LBW). The objective was to determine the extent to which maternal nutrition interventions commenced before conception or in the 1st trimester improved fetal growth in this region. This was a secondary analysis of combined newborn anthropometric data for the South Asian sites (India and Pakistan) in the Women First Preconception Maternal Nutrition Trial. Participants were 972 newborn of mothers who were poor, rural, unselected on basis of nutritional status, and had been randomized to receive a daily lipid-based micronutrient supplement commencing ≥3 months prior to conception (Arm 1), …

Joint-Preserving Procedures For Osteonecrosis Of The Femoral Head., Bülent Atilla, Sancar Bakırcıoğlu, Alexander J. Shope, Javad Parvizi

Rothman Institute Papers

Osteonecrosis of the femoral head is a poorly understood condition that may lead to progressive destruction of the hip joint. Its incidence is common between the third and fifth decades of life and it is the diagnosis behind 5-18% of annually performed total hip arthroplasties (THAs) in the USA.Regarding the high rate of complications of THA in that age group, authors have agreed on the importance of joint-preservation techniques for this disease but techniques vary to establish a generally accepted algorithmic approach.Surgical head-preserving procedures, core decompression with or without graft, stem cell augmentation, or biologic adjuncts, vascularized bone grafting, and …

Extended Prophylactic Antibiotics For Mastectomy With Immediate Breast Reconstruction: A Meta-Analysis, Yang Hai, Weelic Chong, Melissa Lazar

Department of Surgery Faculty Papers

Background: The risk of surgical site infection (SSI) for breast surgery in patients without additional risk factors is low, below 5%. Evidence shows the risk of SSI is significantly elevated in patients undergoing immediate breast reconstruction (IBR). However, there is no consensus regarding the use of extended antibiotic prophylaxis. We aim to determine the effect of extended antibiotic prophylaxis on the incidence of SSI after IBR.

Methods: PubMed and Scopus were searched by 2 independent reviewers. Data abstracted included types of study, basic characteristics, detailed antibiotic prophylaxis information, SSI event, and other secondary outcomes. We calculated the risk ratio (RR) …

Global Health Articles

BACKGROUND: Preterm birth remains a common cause of neonatal mortality, with a disproportionately high burden in low-income and middle-income countries. Meta-analyses of low-dose aspirin to prevent pre-eclampsia suggest that the incidence of preterm birth might also be decreased, particularly if initiated before 16 weeks of gestation.

METHODS: ASPIRIN was a randomised, multicountry, double-masked, placebo-controlled trial of low-dose aspirin (81 mg daily) initiated between 6 weeks and 0 days of pregnancy, and 13 weeks and 6 days of pregnancy, in nulliparous women with an ultrasound confirming gestational age and a singleton viable pregnancy. Participants were enrolled at seven community sites in …

Soliman, Elizabeth A. Stewart, Nelson B. Watts, Ozgul Muneyyirci-Delale

Department of Obstetrics and Gynecology Faculty Papers

BACKGROUND: Uterine fibroids are hormone-responsive neoplasms that are associated with heavy menstrual bleeding. Elagolix, an oral gonadotropin-releasing hormone antagonist resulting in rapid, reversible suppression of ovarian sex hormones, may reduce fibroid-associated bleeding.

METHODS: We conducted two identical, double-blind, randomized, placebo-controlled, 6-month phase 3 trials (Elaris Uterine Fibroids 1 and 2 [UF-1 and UF-2]) to evaluate the efficacy and safety of elagolix at a dose of 300 mg twice daily with hormonal "add-back" therapy (to replace reduced levels of endogenous hormones; in this case, estradiol, 1 mg, and norethindrone acetate, 0.5 mg, once daily) in women with fibroid-associated bleeding. An elagolix-alone …

Microrna And Transcription Factor Co-Regulatory Networks And Subtype Classification Of Seminoma And Non-Seminoma In Testicular Germ Cell Tumors., Guimin Qin, Saurav Mallik, Ramkrishna Mitra, Aimin Li, Peilin Jia, Christine M. Eischen, Zhongming Zhao

Department of Cancer Biology Faculty Papers

Recent studies have revealed that feed-forward loops (FFLs) as regulatory motifs have synergistic roles in cellular systems and their disruption may cause diseases including cancer. FFLs may include two regulators such as transcription factors (TFs) and microRNAs (miRNAs). In this study, we extensively investigated TF and miRNA regulation pairs, their FFLs, and TF-miRNA mediated regulatory networks in two major types of testicular germ cell tumors (TGCT): seminoma (SE) and non-seminoma (NSE). Specifically, we identified differentially expressed mRNA genes and miRNAs in 103 tumors using the transcriptomic data from The Cancer Genome Atlas. Next, we determined significantly correlated TF-gene/miRNA and miRNA-gene/TF …
