This study investigated associations between sedentary bout variables and metabolic health markers in the Hispanic Community Health Study/SOL Youth (Study of Latino Youth). Methods and Results SOL Youth was a population-based cohort of 1466 youth (age range, 8-16 years; 48.5% female); 957 youth were included in the analytic sample based on complete data. Accelerometers measured moderate-to-vigorous physical activity (MVPA), total sedentary time, and sedentary bout patterns (daily time spent in sedentary bouts ≥30 minutes, median sedentary bout duration, …

Progression Of Comorbidities In Youth With Overweight Or Obesity During The Covid-19 Pandemic., Erica Wee, Ashley K. Sherman, Safa Farrukh, Mark A. Clements, Kelsee Halpin, Yun Yan

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Childhood obesity rates have continued to increase with the COVID-19 pandemic. However, data are limited on the impact of increasing obesity on associated comorbidities.

METHODS: We evaluated the progression of overweight- or obesity-associated comorbidities by investigating change in laboratory results pre-COVID-19 pandemic and post-COVID-19 pandemic onset in youth with overweight or obesity. We defined progression of comorbidities based on increase in category rather than absolute change in value.

RESULTS: HbA1c progression was seen in 19%, and LDL cholesterol progression was seen in 26%, as defined by categories. HbA1c progression and LDL cholesterol progression were significantly correlated. HbA1c and LDL …

A Comparative Study Of Postnatal Anthropometric Growth In Very Preterm Infants And Intrauterine Growth., Fu-Sheng Chou, Hung-Wen Yeh, Reese H. Clark

Manuscripts, Articles, Book Chapters and Other Papers

Most growth references for very preterm infants were developed using measurements taken at birth, and were thought to represent intrauterine growth. However, it remains unclear whether the goal of approximating an intrauterine growth rate as stated by the American Academy of Pediatrics is attainable by very preterm infants. Using real-world measurement data from very preterm infants born between 2010 through 2020, we develop models to characterize the patterns of postnatal growth, and compare them to intrauterine growth. By assessing the weight growth rate, we show three phases of postnatal growth not evident in intrauterine growth. Furthermore, postnatal length and head …

Association Of Antimicrobial Perioperative Prophylaxis With Cefuroxime Plus Metronidazole Or Amoxicillin/Clavulanic Acid And Surgical Site Infections In Colorectal Surgery, Elisavet Stavropoulou, Andrew Atkinson, Marie-Christine Eisenring, Christoph A Fux, Jonas Marschall, Laurence Senn, Nicolas Troillet

2020-Current year OA Pubs

OBJECTIVE: To compare intravenous (IV) amoxicillin/clavulanic acid (A/CA) to IV cefuroxime plus metronidazole (C + M) for preventing surgical site infections (SSI) in colorectal surgery.

BACKGROUND: Given their spectra that include most Enterobacterales and anaerobes, C + M is commonly recommended as prophylaxis of SSI in colorectal surgery. A/CA offers good coverage of Enterobacterales and anaerobes as well, but, in contrast to C + M, it also includes Enterococcus faecalis which is also isolated from patients with SSI and could trigger anastomotic leakage.

METHODS: Data from a Swiss SSI surveillance program were used to compare SSI rates after class II …

Virtual Blebbistatin: A Robust And Rapid Software Approach To Motion Artifact Removal In Optical Mapping Of Cardiomyocytes, Louis G Woodhams, Jingxuan Guo, David Schuftan, John J Boyle, Kenneth M Pryse, Elliot L Elson, Nathaniel Huebsch, Guy M Genin

2020-Current year OA Pubs

Fluorescent reporters of cardiac electrophysiology provide valuable information on heart cell and tissue function. However, motion artifacts caused by cardiac muscle contraction interfere with accurate measurement of fluorescence signals. Although drugs such as blebbistatin can be applied to stop cardiac tissue from contracting by uncoupling calcium-contraction, their usage prevents the study of excitation-contraction coupling and, as we show, impacts cellular structure. We therefore developed a robust method to remove motion computationally from images of contracting cardiac muscle and to map fluorescent reporters of cardiac electrophysiological activity onto images of undeformed tissue. When validated on cardiomyocytes derived from human induced pluripotent …

Deep Learning Integrates Histopathology And Proteogenomics At A Pan-Cancer Level, Joshua M Wang, Yize Li, Li Ding, Et Al.

2020-Current year OA Pubs

We introduce a pioneering approach that integrates pathology imaging with transcriptomics and proteomics to identify predictive histology features associated with critical clinical outcomes in cancer. We utilize 2,755 H&E-stained histopathological slides from 657 patients across 6 cancer types from CPTAC. Our models effectively recapitulate distinctions readily made by human pathologists: tumor vs. normal (AUROC = 0.995) and tissue-of-origin (AUROC = 0.979). We further investigate predictive power on tasks not normally performed from H&E alone, including TP53 prediction and pathologic stage. Importantly, we describe predictive morphologies not previously utilized in a clinical setting. The incorporation of transcriptomics and proteomics identifies pathway-level …

The BCL-2 inhibitor Venetoclax is a promising agent for the treatment of acute myeloid leukemia (AML). However, many patients are refractory to Venetoclax, and resistance develops quickly. ATP-binding cassette (ABC) transporters mediate chemotherapy resistance but their role in modulating the activity of targeted small-molecule inhibitors is unclear. Using CRISPR/Cas9 screening, we find that loss of ABCC1 strongly increases the sensitivity of AML cells to Venetoclax. Genetic and pharmacologic ABCC1 inactivation potentiates the anti-leukemic effects of BCL-2 inhibitors and efficiently re-sensitizes Venetoclax-resistant leukemia cells. Conversely, ABCC1 overexpression induces resistance to BCL-2 inhibitors by reducing intracellular drug levels, and high ABCC1 levels …

Pedophilia: Understanding The Origins And Problems Within The Criminal Justice System, James K. Mcelhaney

Doctoral Dissertations and Projects

Societal stigma, criminal sanctions, and the mental illness or disorder of pedophilia are explored in this paper because of the considerable research gaps that have accumulated over the past decade. Most of the data acquired regarding individuals with pedophilia have been predominantly from male offenders, with most of the information coming from reports to local law enforcement and the FBI. The outcome of multiple studies shows that neuroimaging, associated brainwaves, and related sexual attraction are significantly different for individuals with pedophiliac tendencies than for others. Studies also reveal that research has been limited to prevention techniques and therapy for nonoffenders …

Investigating Nurses Lived Experiences Toward Family Presence During Resuscitation To Enhance The Future Of Nursing Curriculum, Laurie Stone

Doctoral Dissertations and Projects

Death is inevitable, but dying alone can be an agonizing prospect for patients and their families. Family presence during resuscitation (FPDR) is a controversial but evidence-based concept that helps relieve some of the fear and anxiety for the family. Sadly, loved ones are often not allowed to be with the patient during resuscitation. FPDR importance is typically taught within the healthcare setting but still lacks implementation. By starting education while healthcare students are in a higher learning setting, this concept has a higher probability of success. To fill the gap concerning FPDR, this researcher interviewed nurses who have witnessed FPDR. …

Immunotherapies have emerged as promising strategies for cancer treatment. However, existing immunotherapies have poor activity in high-grade serous ovarian cancer (HGSC) due to the immunosuppressive tumor microenvironment and the associated low tumoral CD8+ T cell (CTL) infiltration. Through multiple lines of evidence, including integrative analyses of human HGSC tumors, we have identified miR-146a as a master regulator of CTL infiltration in HGSC. Tumoral miR-146a expression is positively correlated with anti-cancer immune signatures in human HGSC tumors, and delivery of miR-146a to tumors resulted in significant reduction in tumor growth in both ID8-p53−/− and IG10 murine HGSC models. Increasing miR-146a expression …

Emerging evidence implicates microbiome involvement in the development of pancreatic cancer (PaCa). Here, we investigate whether increases in circulating microbial-related metabolites associate with PaCa risk by applying metabolomics profiling to 172 sera collected within 5 years prior to PaCa diagnosis and 863 matched non-subject sera from participants in the Prostate, Lung, Colorectal, and Ovarian (PLCO) cohort. We develop a three-marker microbial-related metabolite panel to assess 5-year risk of PaCa. The addition of five non-microbial metabolites further improves 5-year risk prediction of PaCa. The combined metabolite panel complements CA19-9, and individuals with a combined metabolite panel + CA19-9 score in the …

BACKGROUND: Bladder and urinary tract cancers account for approximately 21,000 new diagnoses and 5,000 deaths annually in the UK. Approximately 90% are transitional cell carcinomas where advanced disease is treated with platinum based chemotherapy and PD-1/PD-L1 directed immunotherapy. Urinary tract squamous cell carcinoma (UTSCC) accounts for about 5% of urinary tract cancers overall making this a rare disease. We have yet to establish definitive systemic treatment options for advanced UTSCC. Preliminary translational data, from UTSCC patient tumour samples, indicate high PD-L1 expression and tumour infiltrating lymphocytes in a proportion of cases. Both of these features are associated with differential gene …

Background

Chromosomal microarray analysis (CMA) provides an opportunity to understand genetic causes of congenital heart disease (CHD). The methods for describing cardiac phenotypes in patients with CMA abnormalities have been inconsistent, which may complicate clinical interpretation of abnormal testing results and hinder a more complete understanding of genotype–phenotype relationships.

Methods and Results

Patients with CHD and abnormal clinical CMA were accrued from 9 pediatric cardiac centers. Highly detailed cardiac phenotypes were systematically classified and analyzed for their association with CMA abnormality. Hierarchical classification of each patient into 1 CHD category facilitated broad analyses. Inclusive classification allowing multiple CHD types per …

Sepepquant Enhances The Detection Of Possible Isoform Regulations In Shotgun Proteomics, Yongchao Dou, Yuejia Liu, Xinpei Yi, Lindsey K Olsen, Hongwen Zhu, Qiang Gao, Hu Zhou, Bing Zhang

Faculty, Staff and Students Publications

Shotgun proteomics is essential for protein identification and quantification in biomedical research, but protein isoform characterization is challenging due to the extensive number of peptides shared across proteins, hindering our understanding of protein isoform regulation and their roles in normal and disease biology. We systematically assess the challenge and opportunities of shotgun proteomics-based protein isoform characterization using in silico and experimental data, and then present SEPepQuant, a graph theory-based approach to maximize isoform characterization. Using published data from one induced pluripotent stem cell study and two human hepatocellular carcinoma studies, we demonstrate the ability of SEPepQuant in addressing the key …

Accuracy-Based Glomerular Filtration Rate Assessment By Plasma Iohexol Clearance In Kidney Transplant Donors, Zhicheng Jin, Rongrong Huang, Paul Christensen, Roger L Bertholf, Xin Yi

Faculty, Staff and Students Publications

Background: An accurate measurement of the glomerular filtration rate (GFR) is essential for detecting renal insufficiency in living kidney donors. Iohexol is a "near-ideal" exogenous filtration marker for GFR measurements that has attracted increasing interest in clinical practice because it is non-toxic, non-radioactive, readily available, and easy to measure. In this study, we aimed to set up a laboratory test to conveniently assess the plasma clearance of iohexol in living kidney donors.

Methods: A workflow was established in the institution's infusion clinic to administer iohexol and to collect three timed blood samples from renal transplant donors. Iohexol was thereafter measured …
