Principles Of Hypotensive Shock: A Video Introduction To Pathophysiology And Treatment Strategies, Brittany Macdonald, Nicholas Macdonald, Jacob Garcia, Xiao Chi Zhang, Dimitrios Papanagnou

Department of Emergency Medicine Faculty Papers

Audience: Emergency medicine interns, medical students, and mid-level providers (physician assistants, nurse practitioners).

Introduction: Shock is defined as a state of global tissue hypoxia and is typically the result of hypotension and circulatory system failure. A variety of disease states may ultimately culminate in hypotensive shock through one or more generally recognized mechanisms – hypovolemic, cardiogenic, obstructive, and/or distributive shock. These mechanisms differ significantly in terms of their pathophysiology and requisite treatment. While the effects of hypotensive shock are initially reversible, untreated hypotensive shock may rapidly progress to multiorgan failure and death. Hence, the ability to promptly recognize a state …

Department of Neurology Faculty Papers

Ataxia-telangiectasia (AT) is a rare autosomal recessive neurodegenerative multisystem disorder. A minority of AT patients can present late-onset atypical presentations due to unknown mechanisms. The demographic, clinical, immunological and genetic data were collected by direct interview and examining the Iranian AT patients with late-onset manifestations. We also conducted a systematic literature review for reported atypical AT patients. We identified three Iranian AT patients (3/249, 1.2% of total registry) with later age at ataxia onset and slower neurologic progression despite elevated alpha-fetoprotein levels, history of respiratory infections, and immunological features of the syndrome. Of note, all patients developed autoimmunity in which …

Reinvigorating Immune Response To Advanced Melanoma

Thomas Jefferson University Research Magazine

Melanoma represents a small fraction of skin cancerrelated malignancies, yet accounts for the majority of its mortalities—and the incidence of cutaneous melanoma is rising. While treatments using smalltargeted inhibitors and immune checkpoint antibodies have increased long-term survival in advancedstage cutaneous melanoma, many patients still do not realize any benefit from the treatments. Another group of patients initially have beneficial results but ultimately find their disease progressing, in part due to cancer cells’ acquired resistance to immune response. And still other patients have difficulty with the treatment’s high toxicity.

Striving To Understand Disparities In Cancer Care

Thomas Jefferson University Research Magazine

A key element of the mission of the Sidney Kimmel Cancer Center–Jefferson Health—and an objective of many researchers across the University—is to understand and mitigate the disparities in cancer incidence, treatment and outcome too often experienced by patients who are African American or Latinx, have low incomes or have limited access to care.

In the Philadelphia region, for example, prostate cancer incidence and mortality rates are significantly higher for African Americans than Caucasians, but the causes of this major disparity are unknown. Many researchers have believed that the difference in outcomes results from African American men’s poor clinical response to …

The Relationship Between Malignant Tumors And Ischemic Stroke: Ii. Chronology Of Diagnoses And Treatment Of Strokes, Nóra Hajnóczky, Dániel Bereczki

Department of Medicine Faculty Papers

Összefoglaló. A malignus daganatok és a stroke együttesen gyakran fordulnak elő a stroke tradicionális rizikófaktoraival (magas vérnyomás, hyperlipidaemia, cukorbetegség, elhízás, dohányzás) rendelkező betegekben. Az elmúlt évtized kutatási eredményei alátámasztották, hogy a rosszindulatú daganatban szenvedő betegekben szignifikánsan nagyobb a stroke kockázata. A malignus daganatokhoz társuló stroke a leggyakrabban a malignus daganat diagnózisát követő fél-egy év során jelentkezik. A kapcsolat a másik irányban is létezik: stroke-betegek követése során malignus daganat szignifikánsan gyakrabban jelent meg, mint a stroke-mentes kontrollcsoportban. A daganatot a leginkább a stroke utáni első hat hónapban diagnosztizálják. A korábban nem ismert rosszindulatú daganat időnként az akut stroke kezelése során derül …

Department of Pharmacology and Experimental Therapeutics Faculty Papers

Tumor-associated macrophages (TAMs) promote progression of breast cancer and other solid malignancies via immunosuppressive, pro-angiogenic and pro-metastatic effects. Tumor-promoting TAMs tend to express M2-like macrophage markers, including CD163. Histopathological assessments suggest that the density of CD163-positive TAMs within the tumor microenvironment is associated with reduced efficacy of chemotherapy and unfavorable prognosis. However, previous analyses have required research-oriented pathologists to visually enumerate CD163+ TAMs, which is both laborious and subjective and hampers clinical implementation. Objective, operator-independent image analysis methods to quantify TAM-associated information are needed. In addition, since M2-like TAMs exert local effects on cancer cells through direct juxtacrine cell-to-cell interactions, …

Conventional anti-cancer therapies based on chemo- and/or radiotherapy represent highly effective means to kill cancer cells but lack tumor specificity and, therefore, result in a wide range of iatrogenic effects. A promising approach to overcome this obstacle is spliceosome-mediated RNA trans-splicing (SMaRT), which can be leveraged to target tumor cells while leaving normal cells unharmed. Notably, a previously established RNA trans-splicing molecule (RTM44) showed efficacy and specificity in exchanging the coding sequence of a cancer target gene (Ct-SLCO1B3) with the suicide gene HSV1-thymidine kinase in a colorectal cancer model, thereby rendering tumor cells sensitive to the prodrug ganciclovir (GCV). In …

Vestibular migraine (VM) is an increasingly recognized pathology yet remains as an underdiagnosed cause of vestibular disorders. While current diagnostic criteria are codified in the 2012 Barany Society document and included in the third edition of the international classification of headache disorders, the pathophysiology of this disorder is still elusive. The Association for Migraine Disorders hosted a multidisciplinary, international expert workshop in October 2020 and identified seven current care gaps that the scientific community needs to resolve, including a better understanding of the range of symptoms and phenotypes of VM, the lack of a diagnostic marker, a better understanding of …

Enhancing Precision In Bioprinting Utilizing Fuzzy Systems, Ashkan Sedigh, Dayna Dipiero, Kristy M. Shine, Ryan E. Tomlinson

Department of Orthopaedic Surgery Faculty Papers

Bioprinting facilitates the generation of complex, three-dimensional (3D), cell-based constructs for a variety of applications. Although multiple bioprinting technologies have been developed, extrusion-based systems have become the dominant technology due to the diversity of substrate materials (i.e. bioinks) that can be accommodated, either individually or in combination. Each bioink has unique material properties and extrusion characteristics that limit bioprinting precision, particularly when generating identically shaped constructs from different bioinks. Here, we aimed to achieve high precision (i.e. repeatability) across samples by generating bioink-specific printing parameters using a systematic approach. We hypothesized that a Fuzzy system could be used as a …

Platelet (P), endothelial (E), and leukocyte (L)-selectin molecules may play an important role in PE pathophysiology. We aimed to profile the biomarkers of inflammation, including selectins in PE patients, and compare them to healthy individuals.

Materials and methods: 100 acute PE patients and 50 controls were included in this case control study. ELISA methods were used to quantify levels of selectins, inflammatory, and hemostatic biomarkers.

Results: In PE patients, levels of selectin molecules as compared to controls convey …

Krabbe Disease: A Personal Perspective And Hypothesis, Mohammad Rafi

Department of Neurology Faculty Papers

Introduction: Krabbe disease (KD) or globoid cell leukodystrophy (GLD) is one of the lysosomal disorders affecting central and peripheral nervous systems (CNS and PNS). It is caused by mutations on the galactocerebrosidase (GALC) gene. Affected individuals accumulate undegraded substrates and suffer from neuroinflammation. Methods: Hematopoietic stem cell transplantation (HSCT) has been partially successful in treating patients with KD when accomplished prior to the onset of symptoms. The success is credited to the ability of the hematopoietic stem cells in providing some GALC enzyme to the CNS and eradicating potential neuroinflammation. Combination of the HSCT with some other GALC-providing strategies has …

Multidirectional Instability In Female Athletes, Meghan E. Bishop, Heli Patel, Brandon J. Erickson, Christopher C. Dodson

Rothman Institute Papers

Multidirectional instability (MDI) of the shoulder is characterized by generalized shoulder capsular laxity and symptomatic shoulder instability in more than one direction with one direction of instability as inferior. Generalized ligamentous laxity and specifically shoulder laxity, has been associated with female athletes. While males are at a higher risk of shoulder instability due to a number of extrinsic risk factors including participation in higher risk contact/collision activities, females are particularly susceptible to MDI due to their association with increased joint laxity. Patients with MDI often have a loose patulous capsule and display altered glenohumeral and scapulothoracic mechanics. The mainstay of …
