Role Of A Multidisciplinary Pulmonary Embolism Response Team And Impact Of Interventional Therapy In The Management Of Patients With Intermediate-High Risk Pulmonary Embolism, Juan N Pulido, Robert Fletcher, Michelle A. Poitevin, Kristina Pratt, Paul P Huang, Eric J Lehr, George P Pappas

Articles, Abstracts, and Reports

Background: Despite emerging interventional options for pulmonary embolism (PE), the mortality rate for intermediate high-risk PE (IHR-PE) remains high and the optimal therapeutic approach unclear due to a lack of robust outcomes data. We describe the outcomes of patients presenting with IHR-PE managed by a multidisciplinary PERT program with all available reperfusion options.

Methods: This single center retrospective study included EMR data from patients that were a part of the multidisciplinary PERT program from January 2012 to June 2023. PERT was activated if risk of death was intermediate or higher. The simplified pulmonary embolism severity index (sPESI) and Bova score …

Rapports de recherche scientifique

Les chutes au niveau inférieur sont parmi les 10 premières causes de lésions professionnelles sur la période 2010-2012 et représentent environ 5 000 lésions professionnelles par an, au Québec. Elles représentent également une cause importante de décès au travail (la troisième cause en 2019). La stratégie de protection contre les chutes de hauteur consiste dans un premier temps à éliminer le risque à la source : dans la mesure du possible, il faut éviter les travaux en hauteur. Si cela n’est pas possible, il faut empêcher la chute avec un garde-corps ou l’arrêter par une autre protection collective comme les …

Best Practices In Patient Education: Medical Students’ Perceptions And Implementations, Bridget Croniger, Mikaela Grudzien, Rubab Imtiaz, Dana Kabbani Md, Jennifer Mendez

Internal Medicine Faculty Publications

Effective patient education can help achieve better clinical outcomes, especially when a patient is managing a chronic illness. Despite patient education being an important skill in the professional formation of physicians, little is known about medical students’ perceptions and implementations of such strategies. After completing a chronic illness educational module, second-year medical students were asked to rate the importance of specific patient education strategies and to assess their use of said strategies in the module’s project assignment. Results indicated students utilized different patient education strategies from those they initially identified as most effective.

The Real Cost: Targeted Advertising And Health Outcomes With Nicotine Vaping, Lance Daley

D.U.Quark

Vaping has become a highly popular form of using nicotine in the last decade and is thought to be a less harmful alternative to smoking combustible cigarettes. As popularity continues to increase, especially among teens and young adults, there is still very little information regarding the long-term health effects of vaping. This review will analyze vaping’s fast rise to prominence, negative physiological effects, as well as targeted flavoring and advertising towards youth. Although data is limited, nicotine vaping has been associated with many acute health problems, including increased blood pressure, increased arterial stiffness, and excess free radical production, all of …

School of Medicine Faculty Publications

The emergence of fungicide resistance severely threatens crop production by limiting the availability and application of established fungicides. Therefore, it is urgent to identify new fungicidal targets for controlling plant diseases. Here, we characterized the function of a conserved homoserine O-acetyltransferase (HOA) from the rice blast fungus Magnaporthe oryzae that could serve as the candidate antifungal target. Deletion of the MoMET2 and MoCYS2 genes encoding HOAs perturbed the biosynthesis of methionine and S-adenyl methionine, a methyl group donor for epigenetic modifications, and severely attenuated the development and virulence of M. oryzae. The ΔMomet2 mutant is significantly increased in 5-methylcytosine (5mC) …

Department of Neurosurgery Faculty Papers

BACKGROUND AND OBJECTIVES: Benchmarks represent the best possible outcome and help to improve outcomes for surgical procedures. However, global thresholds mirroring an optimal and reachable outcome for microsurgical clipping of unruptured intracranial aneurysms (UIA) are not available. This study aimed to define standardized outcome benchmarks in patients who underwent clipping of UIA.

METHODS: A total of 2245 microsurgically treated UIA from 15 centers were analyzed. Patients were categorized into low- ("benchmark") and high-risk ("nonbenchmark") patients based on known factors affecting outcome. The benchmark was defined as the 75th percentile of all centers' median scores for a given outcome. Benchmark outcomes …

TP 53-mutant acute myeloid leukemia (AML) remains the ultimate therapeutic challenge. Epichaperomes, formed in malignant cells, consist of heat shock protein 90 (HSP90) and associated proteins that support the maturation, activity, and stability of oncogenic kinases and transcription factors including mutant p53. High-throughput drug screening identified HSP90 inhibitors as top hits in isogenic TP53-wild-type (WT) and -mutant AML cells. We detected epichaperomes in AML cells and stem/progenitor cells with TP53 mutations but not in healthy bone marrow (BM) cells. Hence, we investigated the therapeutic potential of specifically targeting epichaperomes with PU-H71 in TP53-mutant AML based on its preferred binding to …

18s Rrna Methyltransferases Dimt1 And Bud23 Drive Intergenerational Hormesis, Noa Liberman, Eric Lieberman Greer, Et Al.

2020-Current year OA Pubs

Heritable non-genetic information can regulate a variety of complex phenotypes. However, what specific non-genetic cues are transmitted from parents to their descendants are poorly understood. Here, we perform metabolic methyl-labeling experiments to track the heritable transmission of methylation from ancestors to their descendants in the nematode Caenorhabditis elegans (C. elegans). We find heritable methylation in DNA, RNA, proteins, and lipids. We find that parental starvation elicits reduced fertility, increased heat stress resistance, and extended longevity in fed, naïve progeny. This intergenerational hormesis is accompanied by a heritable increase in N6'-dimethyl adenosine (m

Researching The Future: Scenarios To Explore The Future Of Human Genome Editing, Cynthia Selin, Lauren Lambert, Stephanie Morain, John P Nelson, Dorit Barlevy, Mahmud Farooque, Haley Manley, Christopher T Scott

Center for Medical Ethics and Health Policy Staff Publications

Background: Forward-looking, democratically oriented governance is needed to ensure that human genome editing serves rather than undercuts public values. Scientific, policy, and ethics communities have recognized this necessity but have demonstrated limited understanding of how to fulfill it. The field of bioethics has long attempted to grapple with the unintended consequences of emerging technologies, but too often such foresight has lacked adequate scientific grounding, overemphasized regulation to the exclusion of examining underlying values, and failed to adequately engage the public.

Methods: This research investigates the application of scenario planning, a tool developed in the high-stakes, uncertainty-ridden world of corporate strategy, …

Development And Evaluation Of A Wearable Peripheral Vascular Compensation Sensor In A Swine Model Of Hemorrhage, Francesca Bonetta-Misteli, Toi Collins, Todd Pavek, Madison Carlgren, Derek Bashe, Antonina Frolova, Leonid Shmuylovich, Christine M O'Brien

2020-Current year OA Pubs

Postpartum hemorrhage (PPH) is the leading and most preventable cause of maternal mortality, particularly in low-resource settings. PPH is currently diagnosed through visual estimation of blood loss or monitoring of vital signs. Visual assessment routinely underestimates blood loss beyond the point of pharmaceutical intervention. Quantitative monitoring of hemorrhage-induced compensatory processes, such as the constriction of peripheral vessels, may provide an early alert for PPH. To this end, we developed a low-cost, wearable optical device that continuously monitors peripheral perfusion via laser speckle flow index (LSFI) to detect hemorrhage-induced peripheral vasoconstriction. The measured LSFI signal produced a linear response in phantom …

Cobourg's Covid-19 Vaccination Effort: A Model Of Community Engagement For Crisis Response, Sayra Cristancho, Emily Field, Crystal Gaudet

Surgery Publications

For many community members, emergency planning occurs in the background. Community members are not usually engaged in the planning activities. But people see the effects of planning when an emergency strikes. And when responses don’t appear to be happening or appear slow, empowered communities take charge. That’s what happened in Cobourg, Ontario between 2021 and 2022 when the community drove the implementation of the Covid-19 mass vaccination clinic at the Cobourg Community Centre, known as the CCC initiative. In this report, we synthesize the results of a qualitative assessment of the CCC clinic, including lessons and recommendations that other communities …

Cytomegalovirus Esophagitis In An Immunocompromised Patient, Adya A. Ali, Sheela Anasseri, Jaafar Abou-Ghaida, Leslie Walker, Tye Barber

HPD Articles

Cytomegalovirus (CMV) can present with end-organ disease (EOD), particularly in patients with a CD4 cell count <50/mm3. While EOD in immunocompromised patients commonly presents as CMV retinitis (30%) and CMV colitis (5-10%), CMV esophagitis is rare. CMV is the third most common infectious esophagitis following Candida and Herpes Simplex. CMV esophagitis presents with odynophagia, dysphagia, and abdominal pain. Endoscopic exam may reveal large, linear distal esophageal ulcers. Histopathology or serology studies are diagnostic, though serology may be unreliable in the extremely immunosuppressed. Current treatment consists of antivirals such as ganciclovir and valganciclovir. Esophageal disease due to CMV carries a poor prognosis in the immunocompromised. We present the case of a 56-year-old male with a medical history of HIV/AIDS and stage III rectal squamous cell cancer who presented with shortness of breath, weakness, and chronic diarrhea. His HIV was previously well-controlled on antiretroviral therapy. However, due to his malignancy, he was undergoing treatment with chemotherapy and radiation. Initial labs revealed a CD4 count of 42. His clinical course consisted of Escherichia coli septicemia, new-onset atrial fibrillation with a rapid ventricular response, worsening pneumonia, possible metastasis, progressive diarrhea, and potential oropharyngeal candidiasis. Despite several broad-spectrum antimicrobial regimens, he remained symptomatic with new complaints of dysphagia and odynophagia. Eventually, the appearance of vesicular lesions on the lips and a repeat CD4 count of 13 garnered a suspicion of HSV or CMV. This complicated case highlights the necessity for a high index of suspicion of rare manifestations of CMV EOD in an immunocompromised patient presenting with confounding …

Improving Value In Colorectal Cancer Care: An Economic Analysis Of Enhanced Recovery Protocols At A Community Hospital, Lexi Frankel, Amalia D. Ardeljan, Ali Rashid, Abhishek Nair, Kazuaki Takabe, Omar M. Rashid

HPD Articles

Background: Enhanced recovery protocols (ERPs) have been shown to improve the outcomes of gastrointestinal cancer care, leading to reduced morbidity of gastrointestinal treatment and reduced delays in systemic therapy. ERP implementation has also previously shown a reduction in length of stay (LOS) without changing the readmission rate; however, the economic cost associated with these measures has not yet been quantified. The aim of this study was to evaluate the economic costs of ERP implementation for colorectal cancer at a community hospital. Methods: The Diagnostic Related Group (DRG) codes were used to assess costs associated with the hospitalizations of cases in …

Systematic Investigation Of The Homology Sequences Around The Human Fusion Gene Breakpoints In Pan-Cancer – Bioinformatics Study For A Potential Link To Mmej, Pora Kim, Himansu Kumar, Chengyuan Yang, Ruihan Luo, Jiajia Liu, Xiaobo Zhou

Faculty, Staff and Student Publications

Microhomology-mediated end joining (MMEJ), an error-prone DNA damage repair mechanism, frequently leads to chromosomal rearrangements due to its ability to engage in promiscuous end joining of genomic instability and also leads to increasing mutational load at the sequences flanking the breakpoints (BPs). In this study, we systematically investigated the homology sequences around the genomic breakpoint area of human fusion genes, which were formed by the chromosomal rearrangements initiated by DNA double-strand breakage. Since the RNA-seq data is the typical data set to check the fusion genes, for the known exon junction fusion breakpoints identified from RNA-seq data, we have to …

Epicutaneous Sensitization To The Phytocannabinoid Β-Caryophyllene Induces Pruritic Inflammation, Saadet Inan, Sara J Ward, Citlalli T Baltazar, Gabrielle A. Peruggia, Elham Javed, Ajay P. Nayak

Center for Translational Medicine Faculty Papers

In recent years, there has been increased accessibility to cannabis for recreational and medicinal use. Incidentally, there has been an increase in reports describing allergic reactions to cannabis including exacerbation of underlying asthma. Recently, multiple protein allergens were discovered in cannabis, yet these fail to explain allergic sensitization in many patients, particularly urticaria and angioedema. Cannabis has a rich chemical profile including cannabinoids and terpenes that possess immunomodulatory potential. We examined whether major cannabinoids of cannabis such as cannabidiol (CBD) and the bicyclic sesquiterpene beta-caryophyllene (β-CP) act as contact sensitizers. The repeated topical application of mice skin with β-CP at …

Critical Functions Of Extracellular Matrix In Brain Metastasis Seeding, Arseniy E Yuzhalin, Dihua Yu

Faculty, Staff and Student Publications

Human brain is characterized by extremely sparse extracellular matrix (ECM). Despite its low abundance, the significance of brain ECM in both physiological and pathological conditions should not be underestimated. Brain metastasis is a serious complication of cancer, and recent findings highlighted the contribution of ECM in brain metastasis development. In this review, we provide a comprehensive outlook on how ECM proteins promote brain metastasis seeding. In particular, we discuss (1) disruption of the blood-brain barrier in brain metastasis; (2) role of ECM in modulating brain metastasis dormancy; (3) regulation of brain metastasis seeding by ECM-activated integrin signaling; (4) functions of …
