Ethical Implications Of Treatment For Gender Dysphoria In Youth, Kelsey Hayes Nov 2018

Ethical Implications Of Treatment For Gender Dysphoria In Youth, Kelsey Hayes

Online Journal of Health Ethics

This manuscript explores ethical implications on treatment for youth with diagnosed gender dysphoria. The ethical considerations outlined and analyzed in this essay involve illuminating an understanding of whether the administration of pubertal suppression with GnRH agonists, and cross-sex hormones to children with gender dysphoria is morally justified as treatment to manage their psychological distress, or if safer more understood alternatives exist. This essay emphasizes that as health care professionals we must ensure youth with gender dysphoria receive adequate medical treatment and care however, this essay concludes through extensive literature review, that the use of inconclusive and under researched methods to ...

The Joint Commission International (JCI) is responsible for upholding standards in healthcare and organizations in compliance receive accreditation. JCI requires quality improvement on patient safety goals, but requirements may prolong the total procedure/surgery time and reduce efficiency. Here, we evaluate the impact of JCI requirements on time periods in the operating room. We included patients who received elective and emergency surgeries under general anesthesia at Juntendo University Hospital between December 2014 and June 2016. Patients were classified as before and after JCI accreditation on December 12, 2015. The primary outcome was total procedure/surgery time. Secondary outcomes include five ...


Successful Renal Transplantation After Presumed Cyanide Toxicity Treated With Hydroxocobalamin And Review Of The Literature, Ryan J. Hendrix, Paulo N.A. Martins, Jeffrey S. Stoff, Aaron Ahearn, Adel Bozorgzadeh, Babak Movahedi Sep 2018

Successful Renal Transplantation After Presumed Cyanide Toxicity Treated With Hydroxocobalamin And Review Of The Literature, Ryan J. Hendrix, Paulo N.A. Martins, Jeffrey S. Stoff, Aaron Ahearn, Adel Bozorgzadeh, Babak Movahedi

Open Access Articles

We report two cases of successful renal transplantation with allografts from donors who suffered anoxic brain injury as the primary cause of death from house fires. Each was treated prophylactically with hydroxocobalamin (Cyanokit) for suspected cyanide toxicity. During organ procurement, gross examination was notable for deep discoloration of the parenchymal tissues. Approximately 6 and 18 months after transplantation, both recipients have excellent renal graft function and remain independent from hemodialysis (HD). Hydroxocobalamin is the antidote for suspected acute cyanide toxicity. While largely tolerated by the recipient, there is concern over the potential functional implications of the associated side effects of ...

Open Access Articles

To determine appropriate treatment doses of cold atmospheric plasma (CAP), the Canady Helios Cold Plasma Scalpel was tested across numerous cancer cell types including renal adenocarcinoma, colorectal carcinoma, pancreatic adenocarcinoma, ovarian adenocarcinoma, and esophageal adenocarcinoma. Various CAP doses were tested consisting of both high (3 L/min) and low (1 L/min) helium flow rates, several power settings, and a range of treatment times up to 5 min. The impact of cold plasma on the reduction of viability was consistently dose-dependent; however, the anti-cancer capability varied significantly between cell lines. While the lowest effective dose varied from cell line to ...

Ultrasound Guided Placement Of Single-Lumen Peripheral Intravenous Catheters In The Internal Jugular Vein, Tony Zitek, Elizabeth Busby, Heather Hudson, John D. Mccourt, Jamie Baydoun, David E. Slattery

School of Medicine Faculty Publications

Introduction: The peripheral internal jugular (IJ), also called the “easy IJ,” is an alternative to peripheral venous access reserved for patients with difficult intravenous (IV) access. The procedure involves placing a single-lumen catheter in the IJ vein under ultrasound (US) guidance. As this technique is relatively new, the details regarding the ease of the procedure, how exactly it should be performed, and the safety of the procedure are uncertain. Our primary objective was to determine the success rate for peripheral IJ placement. Secondarily, we evaluated the time needed to complete the procedure and assessed for complications. Methods: This was a ...

Proceedings in Obstetrics and Gynecology

High-grade serous ovarian cancer (HGSOC) is the most common and also the most aggressive subtype of ovarian cancer while squamous cell carcinoma (SCC) of the colon is an extremely rare histologic subtype of all colonic malignancies with poor prognosis.

Here we report a unique case of synchronous primary SCC of the colon and second recurrence of HGSOC in a patient with 15-years survival. Our patient developed two recurrent HGSOCs with disease-free survival time of five and nine years, respectively. The second recurrence of HGSOC was associated with the synchronous primary SCC of the ascending colon and was further complicated with ...

Heat Stroke As A Cause Of Liver Failure And Evaluation Of Liver Transplant, Paulo N.A. Martins, Isabel M. A. Bruggenwirth, James Mcdaid, Martin Hertl, Tatsuo Kawai, Nahel Elias, Raymond T. Chung, James F. Markmann

Open Access Articles

Heat stroke is a multiple organ dysfunction syndrome of poorly understood pathogenesis. Exertional heat stroke with acute liver failure is a rarely reported condition. Liver transplant has been recommended as treatment in cases of severe liver dysfunction; however, there are only 5 described cases of long-term survival after this procedure in patients with heat stroke. Here, we present 2 cases of young athletes who developed heat stroke. Both patients developed acute liver failure and were listed for liver transplant. Liver function tests of one patient improved, and he was discharged on postoperative day 13. The other patient showed no signs ...

Open Access Articles

OBJECTIVES: Elevation of transaminases has been used as a marker of hepatic ischemic injury and as a crucial parameter for liver graft assessment. However, analysis of serum transaminases has limitations regarding the quantitative assessment of liver necrosis and is not a reliable predictor of outcomes.

MATERIALS AND METHODS: We retrospectively reviewed the medical records of all liver transplants (N = 238) performed at the UMass Memorial Medical Center from 2009 to 2013.

RESULTS: Fourteen liver grafts showed high peak aminotransferases alanine aminotransferase (ALT) and aspartate aminotransferase (AST) at > 1000 U/L. This high aminotransferase group was compared with 224 donors with ...

Comparing Efficacy Of Lumen-Apposing Stents To Plastic Stents In The Endoscopic Management Of Mature Peripancreatic Fluid Collections: A Single-Center Experience, Matthew J. Fasullo, Yasir Al-Azzawai, Joan Kheder, Jeffrey Abergel, Wahid Y. Wassef

Open Access Articles

Introduction: Mature peripancreatic fluid collection (MPFC) is a known and often challenging consequence of acute pancreatitis and often requires intervention. The most common method accepted is the "step-up approach," which consists of percutaneous drainage followed, if necessary, by minimally invasive retroperitoneal necrosectomy. Our paper aims to distinguish between plastic stents and lumen-apposing stents in the endoscopic management of MPFC in terms of morbidity, mortality, and haste of fluid collection resolution.

Methods: A retrospective analysis was performed at UMass Memorial Medical Center in patients with a diagnosis of MPFC. Utilizing medical records, clinical data, radiology, as well as endoscopic evidence, patients ...

Unique Surgical Approach To A Twisted Ileal-Anal Pouch, Hannah Buettner, Maria X. Kiely, Mengdi Yao, James Yoo, Lilian Chen

Open Access Articles

Total proctocolectomy with ileal pouch-anal anastomosis can restore gastrointestinal continuity in patients requiring colectomy for ulcerative colitis, however, it can be associated with high morbidity. Reoperation for pouch-related complications is technically challenging and often leads to deterioration of pouch function or need for permanent stoma. We report a case of acute on chronic small bowel obstruction secondary to a 360-degree twist in the small bowel introduced during creation of the ileal-anal pouch. Our novel approach at repair has not been reported in past literature which included resection and re-anastomosis of the small bowel proximal to the pouch allowing for pouch ...


Inertial Sensor-Based Variables Are Indicators Of Frailty And Adverse Post-Operative Outcomes In Cardiovascular Disease Patients, Rahul Soangra, Thurmon E. Lockhart Jun 2018

Inertial Sensor-Based Variables Are Indicators Of Frailty And Adverse Post-Operative Outcomes In Cardiovascular Disease Patients, Rahul Soangra, Thurmon E. Lockhart

Physical Therapy Faculty Articles and Research

Cardiovascular disease (CVD) patients with intrinsic cardiac cause for falling have been found to be frail and submissive to morbidity and mortality as post-operative outcomes. In these older CVD patients, gait speed is conjectured by the Society of Thoracic Surgeons (STS) as an independent predictor of post-operative morbidity and mortality. However, this guideline by STS has not been studied adequately with a large sample size; rather it is based largely on expert opinions of cardiac surgeons and researchers. Although one’s gait speed is not completely associated with one’s risk of falls, gait speed is a quick robust measure ...

Failure Of Primary Total Knee Arthroplasty: Establishing A Baseline For Retrieval Analysis Using Well-Functioning Necropsy Specimens, Meredith Perkins May 2018

Failure Of Primary Total Knee Arthroplasty: Establishing A Baseline For Retrieval Analysis Using Well-Functioning Necropsy Specimens, Meredith Perkins

Theses and Dissertations (ETD)

Introduction. Total knee arthroplasty (TKA) is an effective treatment for end-stage osteoarthritis of the knee. While many patients have positive functional and pain outcomes following primary TKA, a subset of patients have suboptimal outcomes, such as unexplained pain or aseptic loosening of the implant components necessitating revision of the index procedure. The understanding of the exact etiology of these suboptimal outcomes of primary TKA is in its infancy. In order to elucidate the etiology of failure in primary TKAs, a baseline for the factors contributing to arthroplasty failure and dissatisfaction must first be established. The purpose of this study was ...

Effects Of Psychiatric Comorbidities On The Perioperative Outcomes Following A Primary Total Arthroplasty, Taylor Smith Apr 2018

Effects Of Psychiatric Comorbidities On The Perioperative Outcomes Following A Primary Total Arthroplasty, Taylor Smith

Carroll College Student Undergraduate Research Festival

This review was conducted to compare the perioperative outcomes following a total primary arthroplasty among patients with a psychiatric comorbidity versus those without a psychiatric comorbidity. Literature was reviewed from the database Pubmed. Seven cohort and case-control studies were reviewed, with the largest sample size of 8.4 million patients. Psychiatric comorbidities resulted in increased negative perioperative outcomes compared to patients without psychiatric comorbidities in six articles. These studies observed higher rates of revision, blood transfusion, mortality, non-traditional discharge, and increased length and cost of stay for patients with a diagnosed psychiatric condition. Therefore, it was concluded from most studies ...

Suspected Blood Indicator To Identify Active Gastrointestinal Bleeding: A Prospective Validation, Samuel Han, Julien Fahed, David R. Cave

Open Access Articles

Background: The suspected blood indicator (SBI) function in the RAPID Reader v8.3 program was designed to quickly identify the presence of blood in video capsule endoscopy. While previous retrospective studies have shown that the SBI function was accurate in detecting the presence of active bleeding in the small bowel, its specificity and sensitivity were poor.

Methods: An initial retrospective review (phase 1) compared 115 patients with active gastrointestinal bleeding seen on video capsule endoscopy (VCE) to 115 patients with no active bleeding seen on VCE to produce a highly accurate algorithm. A prospective study (phase 2) was then performed ...

Lumbar Decompression Surgery: Does Chronic Steroid Use Increase The Risk Of Postoperative Infectious Complications? – A Study Of The National Surgical Quality Improvement Program (Nsqip) Database, Shane Sobrio, Mikel Thista, Raj Rao, Alex Gu, Chapman Wei, Warren Yu

GW Research Days 2016 - Present

Intro: It has long been established that corticosteroids have a negative impact on the human immune system’s ability to function at an optimal level. Many past studies have shown that patient’s will have higher rates of infection if they are taking chronic steroids. What has yet to be established is just how much of an increased risk patients on chronic steroids have for infection after undergoing lumbar decompression surgeries, of which there are thousands per year. We hypothesize that patients on chronic steroids will have higher rates of surgical site infections and higher rates of other infections (UTI ...


Morphine Versus Fentanyl Patient-Controlled Analgesia For Postoperative Pain Control In Major Hepatic Resection Surgeries Including Living Liver Donors: A Retrospective Study, Eman M. Nada, Abdulmajeed Alabdulkareem Apr 2018

Morphine Versus Fentanyl Patient-Controlled Analgesia For Postoperative Pain Control In Major Hepatic Resection Surgeries Including Living Liver Donors: A Retrospective Study, Eman M. Nada, Abdulmajeed Alabdulkareem

Open Access Articles

Background: Liver resection surgery results in significant postoperative pain. However, it is still not clear which opioids used by patient-controlled analgesia (PCA) provides the best pain control and results in the least side effect in a patient with impaired liver function. Our hypothesis was that fentanyl is a better choice than morphine as it is a potent analgesic that its elimination half-life does not depend on the hepatic uptake and metabolism.

The Study Purpose: Is to compare morphine and fentanyl PCA in liver resection patients as regards the degree of pain control, the consumption of opioids, and the side effects ...


The Principles And Practice Of Open Fracture Care, 2018, Amna Diwan, Kyle R. Eberlin, Raymond Malcolm Smith Feb 2018

The Principles And Practice Of Open Fracture Care, 2018, Amna Diwan, Kyle R. Eberlin, Raymond Malcolm Smith

Open Access Articles

The principles of open fracture management are to manage the overall injury and specifically prevent primary contamination becoming frank infection. The surgical management of these complex injuries includes debridement and lavage of the open wound with combined bony and soft tissue reconstruction. Good results depend on early high quality definitive surgery usually with early stable internal fixation and associated soft tissue repair. While all elements of the surgical principles are very important and depend on each other for overall success the most critical element appears to be achieving very early healthy soft tissue cover. As the injuries become more complex ...

Ischemia reperfusion injuries (IRI) are unavoidable in solid organ transplantation. IRI augments alloimmunity but the mechanisms involved are poorly understood. Herein, we examined the effect of IRI on antigen specific alloimmunity. We demonstrate that ischemia promotes alloimmune activation, leading to more severe histological features of rejection, and increased CD4(+) and CD8(+) T cell graft infiltration, with a predominantly CD8(+) IFNgamma(+) infiltrate. This process is dependent on the presence of alloreactive CD4(+) T cells, where depletion prevented infiltration of ischemic grafts by CD8(+) IFNgamma(+) T cells. IL-6 is a known driver of ischemia-induced rejection. Herein, depletion of donor antigen-presenting cells reduced ...

Open Access Articles

Background: Inducible costimulator (ICOS) is rapidly upregulated with T-cell stimulation and may represent an escape pathway for T-cell costimulation in the setting of CD40/CD154 costimulation blockade. Induction treatment exhibited no efficacy in a primate renal allograft model, but rodent transplant models suggest that the addition of delayed ICOS/ICOS-L blockade may prolong allograft survival and prevent chronic rejection. Here, we ask whether ICOS-Ig treatment, timed to anticipate ICOS upregulation, prolongs NHP cardiac allograft survival or attenuates pathogenic alloimmunity.

Methods: Cynomolgus monkey heterotopic cardiac allograft recipients were treated with alphaCD40 (2C10R4, d0-90) either alone or with the addition of delayed ...
