Macrophages infected with Gram-negative bacteria expressing Type III secretion system (T3SS) activate the NLRC4 inflammasome, resulting in Gasdermin D (GSDMD)-dependent, but GSDME independent IL-1β secretion and pyroptosis. Here we examine inflammasome signaling in neutrophils infected with Pseudomonas aeruginosa strain PAO1 that expresses the T3SS effectors ExoS and ExoT. IL-1β secretion by neutrophils requires the T3SS needle and translocon proteins and GSDMD. In macrophages, PAO1 and mutants lacking ExoS and ExoT (ΔexoST) require NLRC4 for IL-1β secretion. While IL-1β release from ΔexoST infected neutrophils is also NLRC4-dependent, infection with PAO1 is instead NLRP3-dependent and driven by the ADP ribosyl transferase activity …

P2X receptors are cation channels that sense extracellular ATP. Many therapeutic candidates targeting P2X receptors have begun clinical trials or acquired approval for the treatment of refractory chronic cough (RCC) and other disorders. However, the present negative allosteric modulation of P2X receptors is primarily limited to the central pocket or the site below the left flipper domain. Here, we uncover a mechanism of allosteric regulation of P2X3 in the inner pocket of the head domain (IP-HD), and show that the antitussive effects of quercetin and PSFL2915 (our nM-affinity P2X3 inhibitor optimized based on quercetin) on male mice and guinea pigs …

Of the 552 lung cancer cases, 387 (70%) died of lung cancer. Cumulative incidence of lung …

Cumulative Incidence Of Physical And Sexual Dating Violence: Insights From A Long-Term Longitudinal Study, Jeff R Temple, Elizabeth Baumler, Leila Wood, Kelli Sargent Franco, Melissa Peskin, Christie Shumate

Faculty, Staff and Student Publications

Decades of inquiry on intimate partner violence show consistent results: violence is woefully common and psychologically and economically costly. Policy to prevent and effectively intervene upon such violence hinges upon comprehensive understanding of this phenomenon at a population level. The current study prospectively estimates the cumulative incidence of sexual and physical dating violence (DV) victimization/perpetration over a 12-year timeframe (2010–2021) using diverse participants assessed annually from age 15 to 26. Data are from Waves 1–13 of an ongoing longitudinal study. Since 2010 (except for 2018 and 2019), participants were assessed on past-year physical and sexual DV victimization and perpetration. Participants …

PURPOSE: The Standardized Definitions for Efficacy End Points (STEEP) criteria, established in 2007 and updated in 2021 (STEEP 2.0), provide standardized definitions of adjuvant breast cancer (BC) end points. STEEP 2.0 identified a need to separately address end points for neoadjuvant clinical trials. The multidisciplinary NeoSTEEP working group of experts was convened to critically evaluate and align neoadjuvant BC trial end points.

METHODS: The NeoSTEEP working group concentrated on neoadjuvant systemic therapy end points in clinical trials with efficacy outcomes-both pathologic and time-to-event survival end points-particularly for registrational intent. Special considerations for subtypes and therapeutic approaches, imaging, nodal staging at …

Faculty, Staff and Students Publications

By combining mass-spectrometry-based proteomics and phosphoproteomics with genomics, epi-genomics, and transcriptomics, proteogenomics provides comprehensive molecular characterization of cancer. Using this approach, the Clinical Proteomic Tumor Analysis Consortium (CPTAC) has characterized over 1,000 primary tumors spanning 10 cancer types, many with matched normal tissues. Here, we present LinkedOmicsKB, a proteogenomics data-driven knowledge base that makes consistently processed and systematically precomputed CPTAC pan-cancer proteogenomics data available to the public through ∼40,000 gene-, protein-, mutation-, and phenotype-centric web pages. Visualization techniques facilitate efficient exploration and reasoning of complex, interconnected data. Using three case studies, we illustrate the practical utility of LinkedOmicsKB in providing …

Kcnq2/3 Gain-Of-Function Variants And Cell Excitability: Differential Effects In Ca1 Versus L2/3 Pyramidal Neurons, Nissi Varghese, Bruno Moscoso, Ana Chavez, Kristen Springer, Erika Ortiz, Heun Soh, Sabato Santaniello, Atul Maheshwari, Anastasios V Tzingounis

Faculty, Staff and Students Publications

Gain-of-function (GOF) pathogenic variants in the potassium channels KCNQ2 and KCNQ3 lead to hyperexcitability disorders such as epilepsy and autism spectrum disorders. However, the underlying cellular mechanisms of how these variants impair forebrain function are unclear. Here, we show that the R201C variant in KCNQ2 has opposite effects on the excitability of two types of mouse pyramidal neurons of either sex, causing hyperexcitability in layer 2/3 (L2/3) pyramidal neurons and hypoexcitability in CA1 pyramidal neurons. Similarly, the homologous R231C variant in KCNQ3 leads to hyperexcitability in L2/3 pyramidal neurons and hypoexcitability in CA1 pyramidal neurons. However, the effects of KCNQ3 …

The Discovery, Characterization, And Engineering Of Autolytic Enzymes As Antimicrobials, Jacob M. Furlon

Dartmouth College Ph.D Dissertations

In an age of rising levels of antibiotic resistance, we are quickly running out of tools to address some of the most virulent and widespread infectious bacteria. One group of enzymes that show significant potential for use as next-generation antibiotics are antimicrobial peptidoglycan hydrolases, often referred to as lysins. These enzymes are responsible for the breakdown of peptidoglycan within the bacterial cell wall, and, when exogenously applied, can result in dramatic destabilization of the cell wall leading to rapid lysis of the bacteria. While phage endolysins have been widely investigated as potential antimicrobials, the therapeutic potential of endogenous autolysins from …

Health disparities are driven by underlying social disadvantage and psychosocial stressors. However, how social disadvantage and psychosocial stressors lead to adverse health outcomes is unclear, particularly when exposure begins prenatally. Variations in the gut microbiome and circulating proinflammatory cytokines offer potential mechanistic pathways. Here, we interrogate the gut microbiome of mother-child dyads to compare high-versus-low prenatal social disadvantage, psychosocial stressors and maternal circulating cytokine cohorts (prospective case-control study design using gut microbiomes from 121 dyads profiled with 16 S rRNA sequencing and 89 dyads with shotgun metagenomic sequencing). Gut microbiome characteristics significantly predictive of social disadvantage and psychosocial stressors in …

Effects Of Computer-Based Cognitive Training Combined With Physical Training For Older Adults With Cognitive Impairment: A Four-Arm Randomized Controlled Trial, I-Ching Chuang, Hui-Yan Chiau, Wan-Wen Liao, Yih-Ru Wu, Chih-Hung Chang, Ching-Yi Wu

2020-Current year OA Pubs

OBJECTIVE: Combined physical (PHY) and cognitive (COG) training in sequential (SEQ) and simultaneous (SIMUL) sessions may delay the progression of cognitive impairment. To date, no study has directly compared in older adults with cognitive impairment the effects of COG training, PHY training, SEQ motor-cognitive training and SIMUL motor-cognitve training on specific indices of cognitive performance and activities of daily living (ADL). The purpose of this study was to determine whether SEQ and SIMUL motor-cognitive training can improve treatment outcomes compared with PHY or COG training alone. We also aimed to compare the effects of SEQ versus SIMUL motor-cognitive training on …

METHODS AND RESULTS: Data from the Behavioural Risk Factor Surveillance System Survey (spanning 2011-22) were used. Multivariable logistic regression models adjusted for potential confounders were applied to calculate average marginal effects (AME), the average difference in the probability of using a given therapy between patients with and without cancer. Outcomes of interest included the use of pharmacological therapies, physical activity, smoking cessation, and post-CVD rehabilitation. Among 5 012 721 respondents, 579 114 reported …

Disentangling Age, Gender, And Racial/Ethnic Disparities In Multiple Myeloma Burden: A Modeling Study, John H Huber, Mengmeng Ji, Yi-Hsuan Shih, Mei Wang, Graham Colditz, Su-Hsin Chang

2020-Current year OA Pubs

Multiple myeloma (MM) is a hematological malignancy that is consistently preceded by an asymptomatic condition, monoclonal gammopathy of undetermined significance (MGUS). Disparities by age, gender, and race/ethnicity in both MGUS and MM are well-established. However, it remains unclear whether these disparities can be explained by increased incidence of MGUS and/or accelerated progression from MGUS to MM. Here, we fit a mathematical model to nationally representative data from the United States and showed that the difference in MM incidence can be explained by an increased incidence of MGUS among male and non-Hispanic Black populations. We did not find evidence showing differences …

Quadruple Valve Replacement In Carcinoid Heart Disease: A Case Report, Maria Beyer, Rishabh Kasarla, Seth Shoap, Erik Beyer

HPD Articles

This report details a rare case of left-sided carcinoid heart disease (CHD). In CHD, vasoactive substances released from carcinoid tumors cause fibrous tissue formation on the right side of the heart. These substances are usually inactivated by monoamine oxidase A in the lungs, safeguarding the left side of the heart. Exceptions include the presence of a patent foramen ovale (PFO), pulmonary metastasis, or elevated serotonin levels. Intriguingly, our patient exhibited significant left-sided involvement without these factors, ultimately requiring a quadruple valve replacement surgery. After eight months post-operation, the patient is stable with no cardiovascular complications. This rare case of CHD, …

Oncology Articles

Recent clinical research describes a subset of glioblastoma patients that exhibit REP prior to the start of radiation therapy. Current literature has thus far described this population using clinicopathologic features. To our knowledge, this study is the first to investigate the potential of conventional radiomics, sophisticated multi-resolution fractal texture features, and different molecular features (MGMT, IDH mutations) as a diagnostic and prognostic tool for prediction of REP from non-REP cases using computational and statistical modeling methods. The radiation-planning T1 post-contrast (T1C) MRI sequences of 70 patients are analyzed. An ensemble method with 5-fold cross-validation over 1000 iterations offers an AUC …

The Therapeutic Potential Of Targeting Cardiac Rgs4., Giselle Del Calvo, Teresa Baggio Lopez, Anastasios Lymperopoulos

HPD Articles

G protein-coupled receptors (GPCRs) play pivotal roles in regulation of cardiac function and homeostasis. To function properly, every cell needs these receptors to be stimulated only when a specific extracellular stimulus is present, and to be silenced the moment that stimulus is removed. The regulator of G protein signaling (RGS) proteins are crucial for the latter to occur at the cell membrane, where the GPCR normally resides. Perturbations in both activation and termination of G protein signaling underlie numerous heart pathologies. Although more than 30 mammalian RGS proteins have been identified, each RGS protein seems to interact only with a …

Thyroid Predictors Of Postpartum Mood Disorders, Sean Backer, Janeta Yancheva, Camelia Garcia, Deepesh Khanna

HPD Articles

Postpartum mood disorders (PMD) are currently among the leading causes of maternal postpartum morbidity and mortality. PMD include the conditions of postpartum blues (PB), postpartum depression (PPD), and postpartum psychosis. The pathogenesis of PMDs are ambiguous, and there are no reliable prenatal predictive markers despite current research efforts. Even though reliable indicators have not been found, leading ideas suggest an etiology of hormonal fluctuations. Although thyroid markers have long been linked to psychiatric disorders such as major depressive disorder (MDD), how they correlate with PMDs is still unclear. This study aimed to evaluate the pathophysiological link between thyroid function, PMDs, …

The Development Of Fat Embolism Syndrome (Fes) And Multiple Small Pulmonary Emboli Following Open Reduction Internal Fixation (Orif) Of A Left Femur Fracture: A Case Report, Aaron Hacker, Dylan S. Irvine, Scott Macdougal, Imani Thornton

HPD Articles

Fat embolism syndrome (FES) is a rare but potentially life-threatening complication that can occur following orthopedic procedures, such as long bone fracture repairs. FES is caused by the release of fat globules into the bloodstream, leading to the obstruction of blood vessels and subsequent tissue damage. Pulmonary embolism (PE), a condition in which a blood clot travels to the lungs, is another potential complication of orthopedic procedures due to the mobilization of blood clots during surgery. We report the case of a 56- year-old female who presented to the emergency department with a left femur fracture following a mechanical fall …

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 …

Discrimination Against Hispanic And African American Women And Interventions To Improve Patient Outcome: An Integrative Review, Sandi Daneri Cruz Rivera

Doctoral Dissertations and Projects

Racial discrimination in health care has been a heavy topic of discussion on social media. Discrimination against women of color such as those of African American and Hispanic descent has been found to have negative health effects. The aim of this project was to identify how racial discrimination influenced African-American and Hispanic women’s health and current interventions that have been implemented to help address these issues. The findings showed that women who experienced discrimination not only in health care but in everyday life did experience negative health outcomes including cardiovascular disparities, obesity, increasing inflammatory markers, and mental health disparities. Implementations …

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. …
