Postnatal Steroid Use To Counter Bronchopulmonay Dysplasia, Aaron Dadzie 2022 The University of Texas Rio Grande Valley

Postnatal Steroid Use To Counter Bronchopulmonay Dysplasia, Aaron Dadzie

MEDI 8127 Scholarly Activities Pre-Clerkship

Chronic Lung Diseases such as bronchopulmonary dysplasia (BPD) are likely the most feared respiratory complication of premature birth. It is characterized by a cessation in lung development that requires the use of oxygen supplemental oxygen and a ventilator and it can lead to long-term pulmonary and neurologic complications. This is combated with the use of postnatal steroids to act as an anti-inflammatory agent to help improve lung function. However, postnatal steroids have become less and less popular in recent years due to the several complications that can arise with their use. This is especially the case if the steroids are ...

The Effect Of Disease Modifying Therapies On Deep Gray Matter: A Longitudinal Comparative Study, Wendy Jin, Evanthia Bernitsas 2022 Wayne State School of Medicine

The Effect Of Disease Modifying Therapies On Deep Gray Matter: A Longitudinal Comparative Study, Wendy Jin, Evanthia Bernitsas

Medical Student Research Symposium

Summary

Cerebral gray matter (GM) atrophy is an important factor in determining disability in Multiple Sclerosis4,9. Disease modifying therapies reduce the GM atrophy to some degree, both in the cortical and deep gray matter (dGM). A previous study has shown that fingolimod (FTY720), asphingosine 1 phosphate immunomodulator can significantly reduced GM and thalamic volume loss in patients with relapsing-remitting Multiple Sclerosis(RRMS)1. In addition to its effect on reducing dGM volume loss, fingolimod is also believed to have protective effect on focal and diffuse dGM damage2,8. The effect of natalizumab on GM atrophy, however, is ...

Background: There is growing awareness and clinical interest in athletes with affective symptoms after sport-related concussion (SRC), as these symptoms may contribute to overall symptoms and represent a modifiable risk factor of longer recovery. However, evidence of their effects on the entire return-to-play (RTP) trajectory, particularly among women and men, is limited.

Purpose/Hypothesis: To examine the relationship between affective symptom reporting and RTP progression after SRC among a cohort of Division 1 student-athletes. We hypothesized that those endorsing affective symptoms, specifically nervous-anxious symptoms, spend more time in RTP progression and recovery.

Study Design: Cohort study; Level of evidence, 3 ...

Mild Traumatic brain injury (mTBI) is a signature wound in military personnel, and repetitive mTBI has been linked to age-related neurogenerative disorders that affect white matter (WM) in the brain. However, findings of injury to specific WM tracts have been variable and inconsistent. This may be due to the heterogeneity of mechanisms, etiology, and comorbid disorders related to mTBI. Non-negative matrix factorization (NMF) is a data-driven approach that detects covarying patterns (components) within high-dimensional data. We applied NMF to diffusion imaging data from military Veterans with and without a self-reported TBI history. NMF identified 12 independent components derived from fractional ...

Exogenous heavy metals or non-metallic waste products, for example lanthanide or iodinated contrast media for radiological procedures, may interfere with the biochemical pools in patients and in common food sources, creating an excess buildup of exogenous compounds which may reach toxic levels. Although the mechanisms are unknown, our experiments were designed to test if this toxicity can be attributed to “transmetallation” or “chelation” reactions freeing up lanthanides or chelated transition metals in acidic fruits used as phantoms representing the biologically active and mineral-rich carbohydrate matrix. The rapid breakdown of stable contrast agents have been reported at a lower pH. The ...


Counting Every Drop: Preventing Maternal Mortality With Quantifying Blood Loss Through Triton Scale, Summer Le 2022 University of San Francisco

Counting Every Drop: Preventing Maternal Mortality With Quantifying Blood Loss Through Triton Scale, Summer Le

Master's Projects and Capstones

Postpartum (PP) hemorrhage is one of the leading causes of maternal mortality (AWHONN, 2021). In each of the past three years, the percentage of PP hemorrhage has increased at Hospital X. The PP unit at Hospital X performs around 4,500 total deliveries each year. While the standard of care for PP blood loss is to specifically measure blood in milliliters as Quantifying Blood Loss (QBL) for Labor and Delivery (L&D), it is not yet the standard of care in the 24 hours postpartum after delivery (ACOG, 2019). This quality improvement project involved educating nurses about measuring blood loss – specifically past the initial measuring in L&D – using the Triton Scale and proper documentation of QBL onto EPIC, the hospital’s electronic patient record system (EPIC). This included creating an instructional video for the Triton Scale, flyers on how to document QBL, emails of changes and implementation, and surveys on nurses’ feedback for QBL implementation. Data collection focused on daily auditing of the nurses’ QBL documentation for the first two voids of a vaginal delivery, QBL for the first four hours of enhanced recovery after surgery (ERAS), and the first eight hours ERAS with ambulation. If a patient hemorrhages, the focus shifts to determine when the nurse notified the Medical Doctor (MD) or Obstetric (OB) rapid response. QBL compliance increased by 96% among all nurses in the PP unit. While QBL compliance increased, it was not statistically significant; however, important steps towards attaining this goal were found. Nurses have demonstrated significant improvements in the ability to use the Triton scale and the ability to properly document their ...

Articles

Confocal Raman microscopy (CRM) has become a versatile technique that can be applied routinely to monitor skin penetration of active molecules. In the present study, CRM coupled to multivariate analysis (namely PLSR—partial least squares regression) is used for the quantitative measurement of an active ingredient (AI) applied to isolated (ex vivo) human stratum corneum (SC), using systematically varied doses of resorcinol, as model compound, and the performance is quantified according to key figures of merit defined by regulatory bodies (ICH, FDA, and EMA). A methodology is thus demonstrated to establish the limit of detection (LOD), precision, accuracy, sensitivity (SEN ...

Journal of Patient-Centered Research and Reviews

Purpose: Electrocardiography (ECG)-derived machine learning models can predict echocardiography (echo)-derived indices of systolic or diastolic function. However, systolic and diastolic dysfunction frequently coexists, which necessitates an integrated assessment for optimal risk-stratification. We explored an ECG-derived model that emulates an echo-derived model that combines multiple parameters for identifying patient phenogroups at risk for major adverse cardiac events (MACE).

Methods: In this substudy of a prospective, multicenter study, patients from 3 institutions (n = 727) formed an internal cohort, and the fourth institution was reserved as an external test set (n = 518). A previously validated patient similarity analysis model was used ...

Background: Radiofrequency catheter ablation (CA) is an efficient antiarrhythmic treatment with a class I indication for idiopathic ventricular arrhythmia (IVA), only when drugs are ineffective or have unacceptable side effects. The accurate prediction of the origins of IVA can significantly increase the operation success rate, reduce operation duration and decrease the risk of complications. The present work proposes an artificial intelligence-enabled ECG analysis algorithm to estimate possible origins of idiopathic ventricular arrhythmia at a clinical-grade level accuracy.

Method: A total of 18,612 ECG recordings extracted from 545 patients who underwent successful CA to treat IVA were proportionally sampled into ...

Large amounts of autism spectrum disorder (ASD) data is created through hospitals, therapy centers, and mobile applications; however, much of this rich data does not have pre-existing classes or labels. Large amounts of data—both genetic and behavioral—that are collected as part of scientific studies or a part of treatment can provide a deeper, more nuanced insight into both diagnosis and treatment of ASD. This paper reviews 43 papers using unsupervised machine learning in ASD, including k-means clustering, hierarchical clustering, model-based clustering, and self-organizing maps. The aim of this review is to provide a survey of the current ...
