Follow Up Care For Heart Failure Patients And Association With Hospital Readmission, Supraja Thunuguntla, Michael Machiorlatti, Sonya Rivera, Juan Cortinas Galvan, Jose Campo Maldonado

School of Medicine Publications

Background:

The CDC reports 6.5 million adults in the US have Heart failure (HF) with yearly costs topping 30 billion. HF patients admitted to Valley Baptist (VB) are readmitted 26% of the time, which is close to the national average of 23% [1]. Standard of care for HF patients is remote nursing care for 30 days from discharge. A hospitalization for any reason within 30 days is considered a “readmission”. On October 1, 2019 at VB remote nursing care changed from weekly house visits to weekly phone calls. The aim of the study is to evaluate the effectiveness of this …

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area …

Pectin-Tannic Acid Nano-Complexes Promote The Delivery And Bioactivity Of Drugs In Pancreatic Cancer Cells, Sumeet S. Chauhan, Advait B. Shetty, Elham Hatami, Pallabita Chowdhury, Murali M. Yallapu

School of Medicine Publications

Pancreatic cancer (PanCa) is a lethal disease. Conventional chemotherapies for PanCa offer severe systemic toxicities. Thus, the development of a successful nanomedicine-based therapeutic regimen with augmented therapeutic efficacy is highly sought. Naturally occurring pectin and modified pectin-based drug delivery systems exhibit remarkable self-targeting ability via galactose residues to various cancer cells. Herein, we developed and used an innovative approach of highly stable nanocomplexes based on modified pectin and tannic acid (MPT-NCs). The nanocomplex formation was enabled by strong intermolecular interactions between pectin and tannic acid under very mild conditions. These nanocomplexes were characterized by particle size and morphology (DLS, TEM, …

Outpatient workup with head CT showed abnormality in the ventral aspect of the left thalamus showing 1.2 × 1 cm low density cyst with approximately 2-3 mm right-left midline shift locally. Left basal ganglia showed multiple well-defined foci of low density measuring up to 3 mm reflecting edema. On admission, pertinent physical exam findings were left sided nystagmus, positive deep tendon reflexes (DTRs) in the right lower extremity (RLE), positive Babinski on the …


Meeting The Educational Needs Of An Increasingly Diverse Surgical Workforce, Minerva Angelica Romero Arenas Mar 2020

Meeting The Educational Needs Of An Increasingly Diverse Surgical Workforce, Minerva Angelica Romero Arenas

School of Medicine Publications

To the Editor Yeo et al1 evaluated factors associated with American Board of Surgery (ABS) examination pass rates in a cohort of categorical surgical residents from the internship (2007) to eligibility/certification. They found that first-time ABS pass rate was associated with nonmodifiable factors, such as nonwhite race/ethnicity, sex (women), and having children.1 Additionally, Hispanic residents were less likely to attempt the ABS examinations at all. We must place these findings in the context of diversity in surgery, or rather, the lack thereof. The cohort included only 55 Hispanic residents, most of whom did pass the ABS examinations (n …

Over-The-Counter Availability Of Levonorgestrel Emergency Contraception In Pharmacies On Oahu, Jennifer Chin, Jennifer Salcedo, Shandhini Raidoo

School of Medicine Publications

Since the United States Food and Drug Administration’s approval of over-the-counter levonorgestrel emergency contraception, access to this time-sensitive medication has improved. However, multiple barriers, including the cost of the medication and pharmacy availability, still exist. The objective of this study was to determine the over-the-counter availability of levonorgestrel emergency contraception in pharmacies on Oahu, Hawaii. We conducted a cross-sectional population-based study using in-person simulated patient encounters at all pharmacies on Oahu. Out of 109 chain pharmacies and 13 independent pharmacies, 102 (84%) pharmacies had levonorgestrel emergency contraception available over the counter. Of pharmacies in which it was available, 12.7% required …

Novel Elvitegravir Nanoformulation For Drug Delivery Across The Blood-Brain Barrier To Achieve Hiv-1 Suppression In The Cns Macrophages, Yuqing Gong, Pallabita Chowdhury, Prashanth K.B. Nagesh, Mohammad A. Rahman, Kaining Zhi, Murali M. Yallapu, Santosh Kumar

School of Medicine Publications

The use of antiretroviral therapy (ART) has remarkably decreased the morbidity associated with HIV-1 infection, however, the prevalence of HIV-1-associated neurocognitive disorders (HAND) is still increasing. The blood-brain barrier (BBB) is the major impediment for penetration of antiretroviral drugs, causing therapeutics to reach only suboptimal level to the brain. Conventional antiretroviral drug regimens are not sufficient to improve the treatment outcomes of HAND. In our recent report, we have developed a poloxamer-PLGA nanoformulation loaded with elvitegravir (EVG), a commonly used antiretroviral drug. The nanoformulated EVG is capable of elevating intracellular drug uptake and simultaneously enhance viral suppression in HIV-1-infected macrophages. …

Recent progress in deciphering mechanisms of human brain cortical folding leave unexplained whether spatially patterned genetic influences contribute to this folding. High-resolution in vivo brain MRI can be used to estimate genetic correlations (covariability due to shared genetic factors) in interregional cortical thickness, and biomechanical studies predict an influence of cortical thickness on folding patterns. However, progress has been hampered because shared genetic influences related to folding patterns likely operate at a scale that is much more local (cm) than that addressed in prior imaging studies. Here, we develop methodological approaches to examine local genetic influences on cortical thickness and …


Dose Response Of The 16p11.2 Distal Copy Number Variant On Intracranial Volume And Basal Ganglia, Ida E. Sønderby, Ómar Gústafsson, Nhat Trung Doan, Nicholas B. Blackburn, John Blangero, Joanne E. Curran, Juan M. Peralta Mar 2020

Dose Response Of The 16p11.2 Distal Copy Number Variant On Intracranial Volume And Basal Ganglia, Ida E. Sønderby, Ómar Gústafsson, Nhat Trung Doan, Nicholas B. Blackburn, John Blangero, Joanne E. Curran, Juan M. Peralta

School of Medicine Publications

Carriers of large recurrent copy number variants (CNVs) have a higher risk of developing neurodevelopmental disorders. The 16p11.2 distal CNV predisposes carriers to e.g., autism spectrum disorder and schizophrenia. We compared subcortical brain volumes of 12 16p11.2 distal deletion and 12 duplication carriers to 6882 non-carriers from the large-scale brain Magnetic Resonance Imaging collaboration, ENIGMA-CNV. After stringent CNV calling procedures, and standardized FreeSurfer image analysis, we found negative dose-response associations with copy number on intracranial volume and on regional caudate, pallidum and putamen volumes (β = −0.71 to −1.37; P < 0.0005). In an independent sample, consistent results were obtained, with significant effects in the pallidum (β = −0.95, P = 0.0042). The two data sets combined showed significant negative dose-response for the accumbens, caudate, pallidum, putamen and ICV (P=0.0032, 8.9 × 10−6, 1.7 × 10−9, 3.5 × 10−12 and 1.0 × 10−4, respectively). Full scale IQ was lower in both deletion and duplication carriers compared to noncarriers. This is the first brain MRI study of the impact of the 16p11.2 distal CNV, and we demonstrate a specific effect on subcortical brain structures, suggesting a neuropathological pattern underlying the neurodevelopmental syndromes.

Extracellular Vesicles From Human Papilloma Virus-Infected Cervical Cancer Cells Enhance Hiv-1 Replication In Differentiated U1 Cell Line, Sabina Ranjit, Sunitha Kodidela, Namita Sinha, Subhash C. Chauhan, Santosh Kumar

School of Medicine Publications

In the current study, we hypothesized that extracellular vesicles (EVs) secreted from human papilloma virus (HPV)-infected cervical cancer cells exacerbate human immunodeficiency virus (HIV)-1 replication in differentiated U1 cell line through an oxidative stress pathway. To test the hypothesis, we treated an HIV-1-infected macrophage cell line (U1) with HPV-infected Caski cell culture supernatant (CCS). We observed a significant increase in HIV-1 replication, which was associated with an increase in the expression of cytochrome P450 (CYPs 1A1 and 2A6) in the CCS-treated U1 cells. Furthermore, we isolated EVs from CCS (CCS-EVs), which showed the presence of CYPs (1A1, 2A6), superoxide dismutase …

Genome-wide association studies (GWAS) for late stage age-related macular degeneration (AMD) have identified 52 independent genetic variants with genome-wide significance at 34 genomic loci. Typically, such an approach rarely results in the identification of functional variants implicating a defined gene in the disease process. We now performed a transcriptome-wide association study (TWAS) allowing the prediction of effects of AMD-associated genetic variants on gene expression. The TWAS was based on the genotypes of 16,144 late-stage AMD cases and 17,832 healthy controls, and gene expression was imputed for 27 different human tissues which were obtained from 134 to 421 individuals. A linear …

Combining Fmri During Resting State And An Attention Bias Task In Children, Anita Harrewijn, Rany Abend, Julia Linke, Melissa A. Brotman, Nathan A. Fox, Ellen Leibenluft, Anderson M. Winkler, Daniel Samuel Pine

School of Medicine Publications

Neuroimaging studies typically focus on either resting state or task-based fMRI data. Prior research has shown that similarity in functional connectivity between rest and cognitive tasks, interpreted as reconfiguration efficiency, is related to task performance and IQ. Here, we extend this approach from adults to children, and from cognitive tasks to a threat-based attention task. The goal of the current study was to examine whether similarity in functional connectivity during rest and an attention bias task relates to threat bias, IQ, anxiety symptoms, and social reticence. fMRI was measured during resting state and during the dot-probe task in 41 children …

Pluronic Polymer-Based Ormeloxifene Nanoformulations Induce Superior Anticancer Effects In Pancreatic Cancer Cells, Neeraj Chauhan, Amber Kruse, Hilary Newby, Meena Jaggi, Murali M. Yallapu, Subhash C. Chauhan

School of Medicine Publications

Utilization of safe cytotoxic agents with precise anticancer activity is considered as the prime focus of cancer therapeutics research. A greater incentive for such agents arises from the molecules/drugs that are already being used for other indications. Ormeloxifene (ORM) is a nonsteroidal, nonhormonal selective estrogen receptor modulator (SERM), which has been in human use for contraception purposes. Although in the recent past, many reports have suggested its emerging role as an anticancer agent, no significant attention was paid toward generating simple and safe nanoformulation( s) for improved therapeutic activity and tumor cell-specific delivery. Our aim is to develop nanoformulation(s) of …

Biophysical Changes Caused By Altered Muc13 Expression In Pancreatic Cancer Cells, Andrew E. Massey, Kyle Doxtater, Murali M. Yallapu, Subhash C. Chauhan

School of Medicine Publications

Background

Pancreatic cancer is one of the most lethal cancers in the United States. This is partly due to the difficulty in early detection of this disease as well as poor therapeutic responses to currently available regimens. Our previous reports suggest that mucin 13 (MUC13, a transmembrane mucin common to gastrointestinal cells) is aberrantly expressed in this disease state, and has been implicated with a worsened prognosis and an enhanced metastatic potential in PanCa. However, there is virtually no information currently to describe the biophysical ramifications of this protein.

Methods

To demonstrate the biophysical effect of MUC13 in PanCa, we …

Objective: The objective of the study was to identify the prevalence and association between CMRFs and kidney function in apparently healthy young adults (18-25 years old).

Methods: We included 5531 freshman year students. Data collected on CMRFs included central obesity, high body mass index (hBMI >25), blood pressure, glycemia, lipids, uric acid (UA >6.8 mg/dL), and insulin. Glomerular filtration rate (GFR) was estimated by CKD-Epidemiology Collaboration formula. We used logistic regression and a log linear for odds ratio (OR) (95% confidence level) and probabilities.

Results: …
