Prognostic Factors Of Myasthenia Gravis Remission After Thymectomy At National Referral Hospital In Indonesia, Suprayitno Wardoyo, Winda J. Layardi

The New Ropanasuri Journal of Surgery

Introduction. Thymectomy is a recommended treatment for myasthenia gravis, enfacing the problem of a low remission rate. However, Indonesian-specific characteristics of myasthenia gravis are somehow different from those of well-developed countries. Thus, identifying prognostic factors influencing remission is required for patient selection to provide optimal preoperative issues.

Methods. A retrospective cohort proceeded in our tertiary hospital, enrolling those diagnosed with myasthenia gravis who underwent thymectomy for four years. Disease period modified Osserman classification, age, sex, preoperative plasmapheresis, preoperative steroid therapy, type of surgery, and thymic pathology were the variables of interest for three-year follow-up. In addition, these variables …

Therapies For Mitochondrial Disorders, Kayli Sousa Smyth, Anne Mulvihill

SURE Journal: Science Undergraduate Research Experience Journal

Mitochondria are cytoplasmic, double-membrane organelles that synthesise adenosine triphosphate (ATP). Mitochondria contain their own genome, mitochondrial DNA (mtDNA), which is maternally inherited from the oocyte. Mitochondrial proteins are encoded by either nuclear DNA (nDNA) or mtDNA, and both code for proteins forming the mitochondrial oxidative phosphorylation (OXPHOS) complexes of the respiratory chain. These complexes form a chain that allows the passage of electrons down the electron transport chain (ETC) through a proton motive force, creating ATP from adenosine diphosphate (ADP). This study aims to explore current and prospective therapies for mitochondrial disorders (MTDS). MTDS are clinical syndromes coupled with abnormalities …

This survey study assessed changes to OUD treatment, telemedicine use, and re-entry support services among carceral and CTPs participating in the National Institute on Drug Abuse (NIDA)-funded study, Long-Acting Buprenorphine vs. Naltrexone Opioid Treatments in Criminal Justice System-Involved Adults (EXIT-CJS) study. In December 2020, carceral sites (n = 6; median pre-COVID 2020 …

Reflecting On The Advancements Of Hfref Therapies Over The Last Two Decades And Predicting What Is Yet To Come, Iliana L. Piña, Gregory T. Gibson, Shelley Zieroth, Rachna Kataria

Division of Cardiology Faculty Papers

What was once considered a topic best avoided, managing heart failure with reduced ejection fraction (HFrEF) has become the focus of many drug and device therapies. While the four pillars of guideline-directed medical therapies have successfully reduced heart failure hospitalizations, and some have even impacted cardiovascular mortality in randomized controlled trials (RCTs), patient-reported outcomes have emerged as important endpoints that merit greater emphasis in future studies. The prospect of an oral inotrope seems more probable now as targets for drug therapies have moved from neurohormonal modulation to intracellular mechanisms and direct cardiac myosin stimulation. While we have come a long …

Indocyanine Green Angiography In Pediatric Colorectal Surgery, Robin B. Wigen

Electronic Thesis and Dissertation Repository

Hirschsprung Disease (HD) and Anorectal Malformations (ARM) are congenital colorectal conditions that necessitate surgical correction via bowel resection with the creation of an anastomosis. Surgical complications, thought to be in part due to malperfusion of the bowel anastomosis, are frequent, as revealed by the retrospective review enclosed. Indocyanine Green Angiography (ICGA) is a process in which water-soluble dye (ICG) is used to assess perfusion of tissue, and it has been employed with success in adult populations to reduce rates of anastomotic leak during colorectal surgery. The systematic review conducted within confirms that this tool has not been extensively studied in …

Reducing Noise Levels In Intensive Care Units Using Noise Monitoring Technology, Kayla Kloes

Symposium of Student Scholars

Intensive care units require many medical procedures, activities, machines, and staff that contribute to high levels of noise.

Training In The Use Of Interpretive Services For Patients With Limited English Proficiency, Kristina Wooten

Symposium of Student Scholars

In clinical settings, there is a disconnect between health care professionals (HCPs) and patients with limited English proficiency (LEP). HCPs rely on ad hoc interpreters to communicate with patients with LEP (e.g. nurses using untrained friends and family or nursing students to interpret care information). Refusing to use or misusing professional interpreters and other interpretive services may lead patients with LEP to avoid seeking necessary care, misunderstand their diagnoses and treatment regimens, and fail to return for follow-up care. This increases the already existing health care disparity between patients who speak English and patients with LEP. Studies show that if …

High Anxiety In Pediatric Oncology Patients? What About Art Therapy?, Rebekah Love

Symposium of Student Scholars

Anxiety and depression are becoming more prevalent in the pediatric population today. In addition to the general pediatric population experiencing an increased risk of mental illness, children with an oncology related diagnosis have an even heightened risk. Most pediatric oncology patients reported fear or worry daily, which is cited to be most severe when they had an appointment or went to the hospital for a fever. It is imperative we discover interventions to lessen the anxiety and depression pediatric oncology patients experience daily. A literature review revealed conclusive interventions have not been determined. The purpose of this research is to …

Reducing Skin Injury And Breakdown In Neonatal Patients, Emily Herring

Symposium of Student Scholars

Abstract

The integumentary system is known for being the body’s largest organ, comprised of water, fats, protein, and minerals, for which composition plays a significant role in protecting the body against thermal, chemical, and microbial agents. However, the skin’s functionality is reduced in neonates as the stratum corneum is thin at birth due to diminished water-holding capacity (Oranges et al., 2015). The skin’s fragility is further stressed among preterm neonates and newborns in neonatal intensive-care units (NICU) due to medical status, procedures, and exposure to skin irritants (Visscher et al., 2009). Reduction in skin injury and breakdown in NICU patients …

Preventing Clabsi In Bedside Nursing, Ashlyn Winegarner

Symposium of Student Scholars

Abstract

Central line associated blood stream infections, better known as CLASBIs, are a prominent problem in the hospital setting. Due to the direct connection between the blood stream and the outside world, these catheters are at great risk for growing infections that can spread to the bloodstream within hours. Research has been done on how compliant registered nurses are in regards to keeping these catheters sterile. A survey was conducted on one hundred and seventy-one nurses that concluded only seventy percent of the nurses were compliant in following the proper central line protocol. Another study was performed that introduced five …

Comparison Of A Dynamic Ankle Orthosis To A Walking Boot For Preserving Ankle Joint Motion And Reducing Tibial Bone Load And Strain, Perri Johnson Jr.

Theses and Dissertations (ETD)

Tibial stress fractures are a common overuse injury accounting for 21.9 – 69% of stress fractures among runners and 24 – 51.2% of stress fractures in military cadets. Current treatment involves wearing a walking boot for 3 – 12 weeks, which limits ankle motion and causes lower limb muscle atrophy. A Dynamic Ankle Orthosis (DAO) provided a distractive force that offloaded the ankle and retained sagittal ankle excursion during walking. It remains unclear how tibial loading is affected by a walking boot or the DAO. This thesis presents a feasibility study confirming the offloading effects of the DAO on tibial …

Effects And Outcomes Of Different Laboring Positions And The Influence From Societal Norms, Amberlyn Heskett

Nursing | Senior Theses

Background

Within labor and delivery, every birth is different. Alarmingly, the U.S. has the highest maternal mortality rate, including death during labor, among developed countries (World Health Organization, 2022). Many maternal deaths may be preventable.

In the U.S., the use of forceps, vacuum-assisted birth, episiotomies, and emergency C-sections are common for women during childbirth. Even though some laboring positions may assist birthing more than others, there often is resistance to allowing various positions due to outside influences, including societal norms, hospital management, and healthcare professional training. Women in labor are vulnerable and look to their nurses for support during the …

Methods Development In Inflammatory Bowel Disease, Andrew B. Steimke

Theses and Dissertations (ETD)

Inflammatory bowel disease (IBD) is a disease that is classified into two subtypes: ulcerative colitis (UC) and Crohn’s disease (CD). Symptoms can range from mild discomfort to requiring surgical intervention and affects approximately 1-in-200 adults in America alone, with global incidence rates increasing. While many treatments exist for IBD, perhaps the main reason for the lack of a cure is that there are many different pathogeneses that all lead to a very similar expression of symptoms. Over 240 IBD loci have been identified to date, yet the causative allele that drives the association has only been identified in ~60 of …
