Nursing Considerations For Post-Traumatic Amnesia After A Traumatic Brain Injury, Hannah Grant
Nursing Considerations For Post-Traumatic Amnesia After A Traumatic Brain Injury, Hannah Grant
Senior Honors Theses
A period known as post-traumatic amnesia (PTA) often follows a traumatic brain injury (TBI). PTA is characterized by anterograde and retrograde amnesia, confusion, disorientation, and agitation. The duration and severity of PTA is a key indicator of the long-term prognosis after a TBI, so proper assessment and nursing care of a PTA patient is crucial. TBIs range from mild to severe, but primarily affect the fronto-temporal lobes. In PTA, both neural lesions and white matter damage within the parahippocampal region can cause PTA. A nurse must perform a thorough assessment of a TBI patient, but, since PTA is a key …

INTRODUCTION: Chemoradiotherapy (CRT) has been associated with increased incidence of cardiovascular (CV) adverse events (CVAE). Coronary artery calcium scoring (CAC) has shown to predict coronary events beyond the traditional CV risk factors. This study examines whether CAC, measured on standard of care, non-contrast chest CT (NCCT) imaging, predicts the development of CVAE in patients with non-small cell lung cancer (NSCLC) treated with CRT.
METHODS: Patients with NSCLC treated with CRT at MD Anderson Cancer Center from 7/2009 until 4/2014 and who had at least one NCCT scan within 6 months from their first CRT were identified. CAC scoring was performed …

Hyperkalemia is one of the more common acute life-threatening metabolic emergencies. The aim of our study is to determine the correlation and accuracy of abnormal ECG parameters as a function of serum potassium concentration in the end-stage renal disease (ESRD) population. We performed a retrospective chart review of emergency department patients presenting with ESRD and receiving emergent hemodialysis treatment. A total of 96 patients, each with five independent ED visits, provided 480 sets of ECGs and electrolytes. Of these, four ECGs were excluded for inability to interpret, leaving a total of 476 patient encounters that met all inclusion criteria. Linear …
Why Is Epinephrine Not The Drug Of Choice In Cardiogenic Shock?, Esther Vorovich
Why Is Epinephrine Not The Drug Of Choice In Cardiogenic Shock?, Esther Vorovich
Journal of Shock and Hemodynamics
Through the years, epinephrine has been the drug of choice for patients with cardiogenic shock. However, epinephrine was clinically inferior to norepinephrine in comparison studies because of the negative patient outcomes, which were statistically significant. These effects include type B lactic acidosis, tachycardia, increased myocardial oxygen demand, and arrhythmias.

Profound Vasoplegia After Coronary Artery Bypass Grafting, Subhasis Chatterjee
Journal of Shock and Hemodynamics
Vasoplegic shock after cardiac surgery is characterized by a high cardiac output, low systemic vascular resistance, refractory hypotension, and ongoing need for vasopressors. In this case, management considerations are discussed, including vasoactive medications and other adjuncts to sustain a satisfactory mean arterial pressure and improve outcomes.
Reperfusion Injury In Acute Myocardial Infarction Shock- Role Of Mechanical Circulatory Support Devices, Finn Gustafsson
Reperfusion Injury In Acute Myocardial Infarction Shock- Role Of Mechanical Circulatory Support Devices, Finn Gustafsson
Journal of Shock and Hemodynamics
The efficacy of mechanical circulatory support in acute myocardial infarction is dependent upon the size of the infarct. If applied early, mechanical support to reduce reperfusion injury appears to be effective in reducing infarct size in animal studies. The optimal timing of reperfusion is uncertain and requires further investigation. Efficient unloading appears to be essential in increasing the efficacy of the type of mechanical support and may favor one over another.
Racial Variations In Shock Presentation And Outcome, Steven Bailey
Racial Variations In Shock Presentation And Outcome, Steven Bailey
Journal of Shock and Hemodynamics
Working toward inclusive strategies for data sampling, trials, and triage is essential. Whatever the approach, it is important to do better than what has been done in the past when considering race and ethnicity in patient care. Although there may be limited publications with information on this topic, they have shown clear differences in patient outcomes with possible associations with gender, race, and ethnicity. It is critical to view the implications of this on socioeconomic status, access, resources, patient phenotypes, and patient desires and expectations. The disparities must first be recognized before any treatment options can be identified.
Hemodynamic Goals In Shock Management: Is There One Target For All?, Maya Guglin
Hemodynamic Goals In Shock Management: Is There One Target For All?, Maya Guglin
Journal of Shock and Hemodynamics
The current guidelines for managing cardiogenic shock lack specificity and clarification. The main criterion for cardiogenic shock is low cardiac output, and the most important goal is to achieve adequate output from a shock state. Because of the complex nature of cardiogenic shock, a “one-size-fits-all" outline may not be the best solution. Historically, hemodynamic goals in cardiogenic shock are copied from septic shock. Because septic shock and cardiogenic shock are different hemodynamic entities, the goals should be different.

Hemodynamics And Kinetics Of Heart Failure With Preserved Ejection Fraction Shock, Yevgeniy Brailovsky, J. Eduardo Rame, Thierry Le Jemtel, Indranee Rajapreyar
Journal of Shock and Hemodynamics
The classical paradigm of cardiogenic shock is severe impairment of left ventricular, right ventricular, or biventricular contractility resulting in decreased cardiac output and end-organ failure. In patients with preserved ejection fraction, cardiogenic shock results from impaired left ventricular filling leading to decreased cardiac output and end-organ hypoperfusion. Heart failure with preserved ejection fraction (HFpEF) comprises a heterogenous group of myocardial and systemic metabolic derangements. Cardiogenic shock with preserved left ventricular ejection is thought to be less common than with reduced left ventricular ejection fraction, and therapeutic approaches are not well standardized. We aim to review the pathophysiology of cardiogenic shock …

Introduction: Hypereosinophilic syndrome (HES) is a rare but detrimental diagnosis in the pediatric population. Cardiac involvement within HES can present as a diagnosis of Eosinophilic Myocarditis which can progress to irreversible damage and potentially death. This case report discusses a 16-year-old male treated for HES, although HES can have overlap with Eosinophilic Granulomatosis with Polyangiitis (EGPA) and requires a multi-disciplinary approach to patient management. Case Description: The patient was a 16-year-old male, with a history of asthma, presenting with acute onset of chest pain. He was found to have peripheral eosinophilia with an absolute eosinophil count of 11.71. He had …

The 'crazy-paving' pattern on high resolution computed tomography (HRCT) is a distinct imaging appearance that is still considered to be a radiological hallmark of pulmonary alveolar proteinosis. However, since its first description about three decades ago, more than 40 different clinical entities presenting as 'crazy-paving' patterns have been documented. This rather remarkable but uncommon imaging appearance is now considered to be a non-specific manifestation. A 62-year-old male referred for evaluation of productive cough, breathlessness and fever presented with 'crazy-paving' pattern on HRCT. Endobronchial biopsy done on presentation was consistent with the diagnosis of squamous cell carcinoma. This report highlights this …

Immunomodulation and immunity from vaccination and natural infection have reduced mortality from coronavirus disease 2019 (COVID-19). However, there are ongoing concerns regarding emerging variants and residual pulmonary sequelae in survivors, given that the lungs are the principal site for the triumvirate of infection, inflammation and injury. The initial waves of acute, severe COVID-19 were profoundly inflammatory, usually manifest as organising pneumonia ± acute respiratory distress syndrome (ARDS). The extent of the fibrogenic potential of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and the modifiability of the pathogenic processes and disease course are unclear. Interestingly patients can develop ‘post-COVID interstitial lung disease’ …

Introduction: Sleep disordered breathing (SDB) is a common condition, associated with multiple comorbidities including cardiovascular and metabolic disease. It has been previously established that SDB is more prevalent in men than women, shifting the literature's focus away from the latter population. As such, underdiagnosis, and thus undertreatment, of SDB in women exists.
Methods: To establish the differences in prevalence, clinical presentation, and pathophysiology of SDB between the two sexes, a narrative review of the current literature was performed.
Results: Rates of SDB are higher among men, likely driven by differences in symptom presentation between men and women, with women presenting …

Recently, it has been suggested that central and peripheral toxicities identified in persons with substance use disorder (SUD) could be partially associated with an imbalance in reactive oxygen species and antioxidant defenses. We conducted a systematic review and meta-analysis to investigate whether SUD is associated with oxidative stress and to identify biomarkers possibly more affected by this condition. We have included studies that analysed oxidant and antioxidant markers in individuals with SUD caused by stimulants, alcohol, nicotine, opioids, and others (cannabis, inhalants, and polysubstance use). Our analysis showed that persons with SUD show higher oxidant markers and lower antioxidant markers …

Understanding how ion channels gate is important for elucidating their physiological roles and targeting them in pathophysiological states. Here, we used SthK, a cyclic nucleotide-modulated channel from Spirochaeta thermophila, to define a ligand-gating trajectory that includes multiple on-pathway intermediates. cAMP is a poor partial agonist for SthK and depolarization increases SthK activity. Tuning the energy landscape by gain-of-function mutations in the voltage sensor domain (VSD) allowed us to capture multiple intermediates along the ligand-activation pathway, highlighting the allosteric linkage between VSD, cyclic nucleotide-binding (CNBD) and pore domains. Small, lateral displacements of the VSD S4 segment were necessary to open the …

Early And Progressive Mobility: A Program Implementation Strategy For High Acuity Patient Care Locations, Stefani Poland
Student Scholarly Projects
Despite an increase in the promotion of early progressive mobility, its decrease in hospital-acquired complications and improvement of patient outcomes, there remains a reluctance in staff commitment to daily evaluation and implementation. This is largely due to the fact nurses or other interprofessional staff are the primary individuals responsible for this change in process. A lack of confidence in staff to correctly identify patients that meet criteria and anxiety regarding the safe transfer or mobilization of patients, particularly in high acuity settings have been identified as major barriers. The PICOT question that guided this program development of a CBO toolkit …

BACKGROUND: The value of polygenic risk scores (PRSs) towards improving guideline-recommended clinical risk models for coronary artery disease (CAD) prediction is controversial. Here we examine whether an integrated polygenic risk score improves the prediction of CAD beyond pooled cohort equations. METHODS: An observation study of 291,305 unrelated White British UK Biobank participants enrolled from 2006 to 2010 was conducted. A case-control sample of 9499 prevalent CAD cases and an equal number of randomly selected controls was used for tuning and integrating of the polygenic risk scores. A separate cohort of 272,307 individuals (with follow-up to 2020) was used to examine …

Dye design can influence the ability of fluorescently labeled imaging agents to generate tumor contrast and has become an area of significant interest in the field of fluorescence-guided surgery (FGS). Here, we show that the charge-balanced near-infrared fluorescent (NIRF) dye FNIR-Tag enhances the imaging properties of a fluorescently labeled somatostatin analogue.

The SARS-CoV-2 (COVID-19) pandemic is a major issue that necessitates the use of cutting-edge disease prediction models. The aim of the study was to assess the existing evidence regarding association between Krebs von den Lungen-6 levels and COVID-19 severity. A literature search was performed on Web of Science, PubMed, Scopus and Cochrane Central Register of Controlled Trials databases from 1 January 2020 up to 2 August 2022. The electronic database search was supplemented by searching Google Scholar. In addition, reference lists of relative articles were also reviewed. KL-6 levels among COVID-19 positive vs. negative patients varied and amounted to 443.37 …
