Colorectal cancer is a leading cause of cancer death in the United States (Mandel, Tanner, Lichtenstein, Metz, Katzka, Ginsberg, & Kochman, 2008; Siegel, DeSantis, & Jemal, 2014). Because this lethal disease claims lives of many people every year, more patients are undergoing screening colonoscopies, which have greatly aided in decreasing the number of colorectal cancer deaths (Siegel et al., 2014). The most common form of sedation for colonoscopies is moderate sedation with a benzodiazepine and an opioid (Cohen, Hightower, Wood, Miller, & Aisenberg, 2004; Lera dos Santos, et. al., 2013). However, sedation by anesthesia providers using propofol is becoming more common and may aid in reducing recovery and discharge times from the postoperative anesthesia care unit (PACU) as well as reducing overall costs. A retrospective chart review (N=176; 88 in propofol group and 88 in benzodiazepine and opioid group) was performed to determine if propofol sedation did reduce discharge times and decrease overall costs for the patient. Patients included in this study ...
Angiosarcoma Of The Lower Extremity Presenting As Bilateral Pneumothoraces, 2017 Marshall University, Huntington, WV
Angiosarcoma Of The Lower Extremity Presenting As Bilateral Pneumothoraces, Mark H. Cooper
Marshall Journal of Medicine
Spontaneous pneumothorax usually presents as unilateral disease. Bilateral spontaneous pneumothoraces are less common and are more likely to be secondary than primary. We describe a case of bilateral spontaneous pneumothoraces that were resistant to conventional treatment, and found ultimately to be secondary to angiosarcoma of the lower extremity. A previously well 49 year old white female was referred to our institution in London with bilateral pneumothoraces. A left video assisted thoracoscopic procedure was undertaken, and the wedge resection of the lung specimen contained an area of metastatic tumor. Talc was placed into the left pleural cavity; talc was also ...

• Pancreatic ductal adenocarcinoma (PDA) is the third leading cause of cancer-related death in the US.
• PDA is resistant to conventional chemotherapy; however, mechanisms that contribute to this chemoresistance are not well-described.
• The tumor microenvironment in PDA has a dense stromal reaction, which is thought to result in low oxygen and low nutrient conditions (Feig, C., et al. 2012).
• Isocitrate Dehydrogenase 1 (IDH1) has been identified as an enzyme that plays an important role in chemoresistance in PDA (Zarei, M., et al. In progress).
• We sought to establish an IDH1 knockout cell line to further study its role in PDA ...

BACKGROUND: Endocrine therapy is standard treatment for estrogen receptor (ER)-positive breast cancer. However, its efficacy is limited by intrinsic and acquired resistance. Here the potential of S100β as a biomarker and inhibition of its signaling network as a therapeutic strategy in endocrine treated patients was investigated.
METHODS: The expression of S100β in tissue and serum was assessed by immunohistochemistry and an enzyme-linked immunosorbent assay, respectively. The S100β signaling network was investigated in cell line models of endocrine resistance by western blot, PCR, immunoprecipitation, and chromatin-immunoprecipitation. Endocrine resistant xenografts and tumor explants from patients with resistant tumors were treated with ...
Therapeutic Application Of Carbon Monoxide In Acute Limb Compartment Syndrome, 2017 The University of Western Ontario
Therapeutic Application Of Carbon Monoxide In Acute Limb Compartment Syndrome, Aurelia Bihari
Electronic Thesis and Dissertation Repository
Acute limb compartment syndrome (CS), a devastating complication of musculoskeletal trauma, develops in response to elevation of the pressure within a closed osseofascial compartment, producing muscle- and limb-threatening ischemia. Full decompression of all involved compartments by fasciotomy is the current gold-standard therapy, but it must be performed within a surgical window of 6-8 hours, before tissue damage becomes permanent.
Carbon monoxide (CO), a byproduct of heme metabolism, has been shown protective in ischemia. While inhalation of CO leads to elevation of carboxyhemoglobin (COHb), recent development of transitional metal carbonyls, CO-releasing molecules (CO-RMs), particularly the water-soluble CORM-3, delivers CO in a ...
A Review Of Pain Control In Pediatric Cardiac Bypass Surgery, 2017 George Washington University
A Review Of Pain Control In Pediatric Cardiac Bypass Surgery, Pranathi Ari, Andrew T. Waberski, Nina Deutsch
GW Research Days 2016 - Present
Background: Children undergoing cardiac surgery with cardiopulmonary bypass receive high dose opioids for analgesia and to reduce the neurohormonal stress response. While opioids have excellent pharmacodynamics profiles adverse effects include: respiratory depression, bradycardia, nausea, vomiting, and tolerance. Additionally, opioids with short half-lives like fentanyl require several boluses to be administered during surgery causing fluctuating levels analgesia. Several strategies to advance pain control incorporate regional and neuraxial anesthetic techniques, however anticoagulation preclude its routine use. Alternatively using opioids with longer half-lives for analgesia may improve pain control and reduce adverse effects.
Objective: The objective of this study is to quantify postoperative ...

Tuberculosis is in the top 10 causes of death worldwide, being one of the most deadly infectious diseases. It is estimated that one of three people from the entire earth population has a latent infection with M tuberculosis. This aerobic bacterium possesses the ability to persist in host tissues for years and to begin replication once immunity declines.
The lungs are most frequent site of infection as the Mycobacterium tuberculosis is carried by aerosol droplets and is commonly transmitted by respiratory route. The second way of transmission is by contaminated food.
Intestinal contamination coexists with pulmonary tuberculosis and only 10 ...

NYMC Student Posters
BACKGROUND: Hospital readmission after major colorectal surgery is a major economic burden and a benchmark of quality care by government agencies. We hypothesized that a post-discharge telephone follow-up (TFU) could reduce readmission after abdominal colorectal surgery.
METHODS: Consecutive patients undergoing abdominal colorectal surgery over the 4-month period ending Oct 2016 were prospectively evaluated. A structured TFU call during the 4-day period after hospital discharge evaluating the patient’s clinical status and possible interventions to avoid readmission was conducted by a second-year medical student, supervised by two board certified colorectal surgeons. Readmission rates were compared to a control group undergoing abdominal ...

Prone Position: Does It Help With Acute Respiratory Distress Syndrome (Ards) Requiring Extracorporeal Membrane Oxygenation (Ecmo)?, Nava Azimzadeh, Michael Baram, Nicholas C. Cavarocchi, Hitoshi Hirose
Department of Surgery Faculty Papers
Introduction: Lung protective ventilation therapy with low tidal volume-high PEEP is the standard treatment for the patients with acute respiratory distress syndrome (ARDS). Oscillators are occasionally used for salvage ventilation in cases where poor compliance restricts the use of traditional ventilation with ARDS. In addition to ventilator therapy, prone positioning has been used to improve oxygenation. We presented a challenging case of ARDS, which failed medical management extracorporeal membrane oxygenation (ECMO) support and oscillatory ventilation. Prone positioning was initiated which improved oxygenation, respiratory compliance and posterior atelectasis. Case presentation: A 41-year-old morbid obese female developed ARDS due to influenza pneumonia ...
Prospects And Limitations Of Improving Skeletal Growth In A Mouse Model Of Spondyloepiphyseal Dysplasia Caused By R992c (P.R1192c) Substitution In Collagen Ii., Machiko Arita, Jolanta Fertala, Cheryl Hou, James Kostas, Andrzej Steplewski, Andrzej Fertala
Department of Orthopaedic Surgery Faculty Papers
Skeletal dysplasias form a group of skeletal disorders caused by mutations in macromolecules of cartilage and bone. The severity of skeletal dysplasias ranges from precocious arthropathy to perinatal lethality. Although the pathomechanisms of these disorders are generally well defined, the feasibility of repairing established aberrant skeletal tissues that developed in the presence of mutant molecules is currently unknown. Here, we employed a validated mouse model of spondyloepiphyseal dysplasia (SED) that enables temporal control of the production of the R992C (p.R1192C) collagen II mutant that causes this disease. Although in our earlier studies we determined that blocking the expression of ...

When patients present with life threatening conditions, a rapid cost-benefit analysis prioritizes care and commits treatment to a certain course that, in the case of ST Elevation Myocardial Infarction (STEMI) treated with drug-eluting stents (DES), could be fatal if there is any deviation. Antiplatelet therapy is vital and secondary concerns (i.e. bleeding diatheses) may accept suboptimal outcomes – in rare cases, another life-threatening condition may be unmasked, the treatment for which runs directly counter to the first. We present a case of STEMI with high clot burden treated with multiple DES, complicated by retroperitoneal hemorrhage due to a ruptured abdominal ...

The tumor suppressor gene HIC1 (Hypermethylated In Cancer 1) encodes a transcriptional repressor mediating the p53-dependent apoptotic response to irreparable DNA double-strand breaks (DSBs) through direct transcriptional repression of SIRT1. HIC1 is also essential for DSB repair as silencing of endogenous HIC1 in BJ-hTERT fibroblasts significantly delays DNA repair in functional Comet assays. HIC1 SUMOylation favours its interaction with MTA1, a component of NuRD complexes. In contrast with irreparable DSBs induced by 16-hours of etoposide treatment, we show that repairable DSBs induced by 1 h etoposide treatment do not increase HIC1 SUMOylation or its interaction with MTA1. Furthermore, HIC1 SUMOylation ...
