Locoregional Therapy Pressure-Enabled Drug Delivery For Liver Cancers, Thomas Eggleston, Bassem Fayek, Jacqueline Kowalke, Mina Makary

Student Papers, Posters & Projects

Hepatic malignancies account for a substantial portion of global cancer mortality, with hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (IHC), and metastatic liver disease representing the most common diagnoses. While surgical resection and liver transplantation remain curative options for eligible patients, most patients are diagnosed at stages unsuitable for surgery. This has shifted medical management towards locoregional therapies (LRTs) which are often catheter-directed. Of these interventions, the use of conventional end-hole catheters for therapeutic infusion has been a mainstay of treatment, but this method is constrained by retrograde particle escape and elevated tumoral interstitial fluid pressure. Together, these factors limit drug penetration …

Editorial: Participatory And Just Governance: Empowering Local And Indigenous Communities, Melissa Haeffner, Maiko Sakamoto, Jenia Mukherjee, Hong Quan Nguyen, Soyo Takahashi

Environmental Science and Management Faculty Publications and Presentations

The papers in this Research Topic (RT) extend insights on the roles of social relations, institutional arrangements, Indigenous ways of knowing, local knowledge, and decisionmaking participation in shaping water governance and practice. Despite efforts to predict flows and possible hazards, we continue to observe “unintended consequences” when humans interact with waterscapes. What we often learn, we argue, is that what appears “unintended” often reflects a deliberate architecture of exclusion; one that becomes legible only when social power relations are placed at the center of analysis alongside hydrological variables. Doing so may illuminate where injustice complicates intentions and what difference participatory …

From The Forests With Hopes Of Paradise: Malay Muslims In The Victorian Imagination In Joseph Conrad's Lord Jim, M Irfan Zamzami, Rifka Pratama

Journal of Language, Literature, and Arts

This article examines how Lord Jim constructs and reconfigures Muslim identities within the discourse of British imperialism. While previous scholarship has explored the novel’s colonial politics, less attention has been paid to how its representations of Malay Muslims reveal the instability of Orientalist categories. Using Edward Said’s concept of Orientalism and Homi Bhabha’s theory of colonial ambivalence, the study applies close textual analysis of two key narrative moments: the omniscient narrator’s description of the Muslim pilgrims aboard the Patna and the depiction of Malay Muslims in Patusan. The analysis demonstrates that the Patna pilgrims are initially represented through familiar Orientalist …

A Multimodal Approach To The Treatment Of Primary Chronic Pelvic Pain In Adult Women: The Positive Impact Of Shared Decision Making On Health Outcomes, Kylie Freese

Summer Interdisciplinary Research Symposium

Objective:

The goal of this paper was to assess approaches to management of idiopathic chronic pelvic pain (ICPP) in females to improve health outcomes.

Methods:

A structured literature search was conducted in the MEDLINE and CINAHL databases. Studies were included if they evaluated therapeutic interventions for primary/idiopathic chronic pelvic pain in adult females and reported treatment outcomes. Studies with adolescents, males, non-treatment topics, diagnostics, or unrelated conditions were excluded.

Results:

Myofascial therapy resulted in relief of anxiety and depression (-4.0+/-3.2, p< 0.001; -3.4+/-2.5, p< 0.001) and female sexual function index (FSFI) (7.8+/-6.4, p< 0.001). Psychological approaches had similar results regarding pain improvement, however showed worsening of FSFI (-0.31 [ -0.95, 0.34]; -1.95 [-3.63, -0.28]). Duloxetine and amitriptyline trials displayed improvement in pain, with amitriptyline impacting urinary symptoms and duloxetine resulted in lower pain scores. Cannabidiol improved pain, sleep, and mood disturbances (p≤0.001). Multimodal treatment resulted in greater improvement in pain (-2.19, [-3.17, -1.22], p=0.002) and FSFI (2.47, [1.06,3.88], p=0.030). No study showed statistically significant data displaying improvement/worsening quality of life.

Conclusion:

Each individual treatment resulted in improvements in the measured outcomes. Multimodal treatment approaches result in greatest outcomes when …
