Analyzing And Mitigating The Risks Of Patient Harm During Operating Room To Intensive Care Unit Patient Handoffs., Nara Regina Spall Martins, Edson Zangiacomi Martinez, Cláudia Marquez Simões, Paul Barach, Maria José Carvalho Carmona

SKMC Student Presentations and Publications

Patients continue to suffer from preventable harm and uneven quality outcomes. Reliable clinical outcomes depend on the quality of robust administrative systems and reliable support processes. Critically ill patient handoffs from the operating room (OR) to the intensive care unit (ICU) are known to be high-risk events. We describe a novel perspective on how risk factors associated with the process of patient handoff communication between the OR and the ICU can lead to flawed communication, degraded team awareness, medical errors, and increased patient harm. Data were collected from two semi-structured focus groups using a five-step risk management approach at a …

Il-1Β In Neoplastic Disease And The Role Of Its Tumor-Derived Form In The Progression And Treatment Of Metastatic Prostate Cancer, Yetunde Oyende, Luke Taus, Alessandro Fatatis

Kimmel Cancer Center Faculty Papers

Since its discovery, IL-1β has taken center stage as a key mediator of a very broad spectrum of diseases revolving around immuno-mediated and inflammatory events. Predictably, the pleiotropic nature of this cytokine in human pathology has led to the development of targeted therapeutics with multiple treatment indications in the clinic. Following the accumulated findings of IL-1β's central modulatory role in the immune system and the implication of inflammatory pathways in cancer, the use of IL-1β antagonists was first proposed and then also pursued for oncology disorders. However, this approach has consistently relied on the perceived need of interfering with IL-1β …

Revisiting Phosphoregulation Of Cdc25c During M-Phase Induction, Tan Tan, Chuanfen Wu, Ruoning Wang, Bih-Fang Pan, David Hawke, Fumin Yin, Zehao Su, Boye Liu, Sue-Hwa Lin, Wei Zhang, Jian Kuang

Faculty, Staff and Student Publications

Cdc25C undergoes a sudden and substantial gel mobility shift at M-phase onset, correlating with abrupt activation of both Cdc25C and Cdk1 activities. A positive feedback loop between Cdk1 and Cdc25C has been used to explain this hallmark phenomenon. Here, we demonstrate that the M-phase supershift and robust activation of Cdc25C are due to the site-comprehensive phosphorylation of its long intrinsically disordered regulatory domain without requiring Cdk1 or other major mitotic kinase activities. The phosphorylation process involves substrate-mediated assembly of phosphorylation machinery that catalyzes multisite phosphorylation continuously without substrate dissociation. In contrast to the site-comprehensive phosphorylation of Cdc25C occurring at M-phase …

Innervation Of Human Intestinal Organoids, Rachel C Bordelon, Madushani Herath, Allison L Speer

Faculty, Staff and Student Publications

The complexity of intestinal cytoarchitecture and function poses significant challenges for the creation of the bioengineered small intestine. Techniques for generating human intestinal organoids (HIOs) resembling human small intestine have been previously reported. HIOs contain epithelium and mesenchyme but lack other critical components of functional intestine such as the enteric nervous system (ENS), immune cells, vasculature, and microbiome. Two independent research groups have published distinct methods to innervate HIOs with an ENS. Here we discuss a unique method of incorporating the ENS into an HIO-derived bioengineered small intestine, which utilizes components of these prior reports to optimize progenitor cell identity …

Supplementary Motor Area In Speech Initiation: A Large-Scale Intracranial Eeg Evaluation Of Stereotyped Word Articulation, Latané Bullock, Kiefer J Forseth, Oscar Woolnough, Patrick S Rollo, Nitin Tandon

Faculty, Staff and Student Publications

Speech production engages a distributed network of cortical and subcortical brain regions. The supplementary motor area (SMA) has long been thought to be a key hub in coordinating across these regions to initiate voluntary movements, including speech. We analyzed direct intracranial recordings from 115 patients with epilepsy as they articulated a single word in a subset of trials from a picture-naming task. We aimed to characterize the temporal dynamics of SMA relative to other cortical regions. SMA and preSMA were among the first regions to activate after cue onset, peaked in activity before articulation onset, and were the earliest regions …

Arthritis leads to bone erosion due to an imbalance between osteoclast and osteoblast function. Our prior investigations revealed that the Ca2+-selective ion channel, Orai1, is critical for osteoclast maturation. Here, we show that the small-molecule ELP-004 preferentially inhibits transient receptor potential canonical (TRPC) channels. While ELP-004 minimally affected physiological RANKL-induced osteoclast maturation in murine bone marrow- and spleen-derived myeloid cells (BMSMCs) and human PBMC-derived cells, it potently interfered with osteoclast maturation driven by TNFα or LTB4. The contribution of TRPC channels to osteoclastogenesis was examined using BMSMCs derived from TRPC4-/- or TRPC(1-7)-/- mice, again revealing preferential interference with osteoclastogenesis driven …

Peritoneal carcinomatosis (PC) in gastric adenocarcinoma (GAC) is the most common metastatic site and leads to a short median survival. Exosomes have been shown to remodel the microenvironment, facilitating tumor metastases. However, the functional component in GAC cell-derived exosomes that remodel the landscape in the peritoneal cavity remains unclear. To address this, we performed in-depth proteomic profiling of ascites-derived exosomes from patients with PC, and we found that Galectin-3 was highly enriched in exosomes derived from malignant ascites. exosomal Galectin-3 was the crucial regulator of PC. Blockage of exosomal Galectin-3 significantly inhibited tumor metastases and prolonged overall survival. Exosomal Galectin-3 …

Colorectal cancer (CRC) is the third most common cancer worldwide, with rising prevalence among younger adults. Several lifestyle factors, particularly disruptions in circadian rhythms by light-dark (LD) shifts, are known to increase CRC risk. Epidemiological studies previously showed LD-shifts are associated with increased risk of CRC. To explore the mechanisms and interactions between LD-shift and intestinal aging, we investigated how the combination of LD-shifts and aging impacts colon carcinogenesis development. Our data showed that LD-shifts and aging increased colon tumorigenesis. Notably, LD-shift accelerated intestinal aging by altering aging-related pathways, such as intestinal barrier damage, accompanied by dysbiotic changes in the …

Alpha Synuclein And Inflammaging, Geneviève L. Putnam, Robert W. Maitta

Faculty Scholarship

The α-synuclein protein is an established molecule in Lewy body pathology, especially Parkinson's disease (PD). While the pathological role of α-synuclein (α-syn) in PD has been well described, novel evidence may suggest that α-syn interacts with inflammasomes in response to aging. As age is an inevitable physiological state and is also considered the greatest risk factor for PD, this calls for investigation into how α-syn, aging, and PD could be linked. There is a growing amount of data regarding α-syn normal function in the body that includes involvement in cellular transport such as protein complexes assembly, vesicular trafficking, neurotransmitter release, …

Neonatal health is dependent on early risk stratification, diagnosis, and timely management of potentially devastating conditions, particularly in the setting of prematurity. Many of these conditions are poorly predicted in real-time by clinical data and current diagnostics. Umbilical cord blood may represent a novel source of molecular signatures that provides a window into the state of the fetus at birth. In this study, we comprehensively characterized the cord blood proteome of infants born between 25 to 42 weeks using untargeted mass spectrometry and functional enrichment analysis. We determined that the cord blood proteome at birth varies significantly across gestational development. …

Neutralizing Antibody Immune Correlates In Covail Trial Recipients Of An Mrna Second Covid-19 Vaccine Boost, Bo Zhang, Rachel M Presti, Et Al.

Transcription elongation, especially RNA polymerase II (Pol II) pause-release, is less studied than transcription initiation in regulating gene expression during meiosis. It is also unclear how transcription elongation interplays with transcription initiation. Here, we show that depletion of NKAPL, a testis-specific protein distantly related to RNA splicing factors, causes male infertility in mice by blocking the meiotic exit and downregulating haploid genes. NKAPL binds to promoter-associated nascent transcripts and co-localizes with DNA-RNA hybrid R-loop structures at GAA-rich loci to enhance R-loop formation and facilitate Pol II pause-release. NKAPL depletion prolongs Pol II pauses and stalls the SOX30/HDAC3 transcription initiation complex …

Viruses engage in a variety of processes to subvert host defenses and create an environment amenable to replication. Here, using rotavirus as a prototype, we show that calcium conductance out of the endoplasmic reticulum by the virus encoded ion channel, NSP4, induces intercellular calcium waves that extend beyond the infected cell and contribute to pathogenesis. Viruses that lack the ability to induce this signaling show diminished viral shedding and attenuated disease in a mouse model of rotavirus diarrhea. This implicates nonstructural protein 4 (NSP4) as a virulence factor and provides mechanistic insight into its mode of action. Critically, this …

Class Iii Phosphatidylinositol-3 Kinase/Vacuolar Protein Sorting 34 In Cardiovascular Health And Disease, Yuanjun Shen, Jason Gleghorn

Pharmacy Faculty Scholarship

Phosphatidylinositol-3 kinases (PI3Ks) play a critical role in maintaining cardiovascular health and the development of cardiovascular diseases (CVDs). Specifically, vacuolar Protein Sorting 34 (VPS34) or PIK3C3, the only member of Class III PI3K, plays an important role in CVD progression. The main function of VPS34 is inducing the production of phosphatidylinositol 3-phosphate, which, together with other essential structural and regulatory proteins in forming VPS34 complexes, further regulates the mammalian target of rapamycin activation, autophagy, and endocytosis. VPS34 is found to have crucial functions in the cardiovascular system, including dictating the proliferation and survival of vascular smooth muscle cells and cardiomyocytes …
