The COVID-19 pandemic reminded us of the urgent need for new antivirals to control emerging infectious diseases and potential future pandemics. Immunotherapy has revolutionized oncology and could complement the use of antivirals, but its application to infectious diseases remains largely unexplored. Nucleoside analogs are a class of agents widely used as antiviral and anti-neoplastic drugs. Their antiviral activity is generally based on interference with viral nucleic acid replication or transcription. Based on our previous work and computer modeling, we hypothesize that antiviral adenosine analogs, like remdesivir, have previously unrecognized immunomodulatory properties which contribute to their therapeutic activity. In the case …

Acquired hemophilia A (AHA) is a clotting disorder characterized by the presence of neutralizing antibodies that inhibit factor VIII, resulting in increased bleeding risk. Known etiologies include malignancy, autoimmune conditions, graft-vs-host disease, and more recently coronavirus disease 2019 (COVID-19) infection. In this case report, we describe an 86-year-old female who was found to have AHA incidentally during preoperative workup for meningioma resection. She was subsequently found to have COVID-19 infection which was the likely cause of her development of AHA. She was treated with factor eight inhibitor bypassing agent (FEIBA) and recombinant factor VII (rVII) for a small hematoma on …

Background; Physical activity after surgical resection for colon cancer is associated with significantly longer disease-free survival. Inflammation is hypothesized to mediate the association between physical activity and disease-free survival in colon cancer. Methods; In this exploratory analysis of a randomized dose-response trial, 39 colon cancer survivors who completed standard therapy were stratified by cancer stage and randomized in a 1;1;1 ratio to one of three treatment groups for 24 weeks of usual-care control, 150 min/wk of moderate-intensity aerobic exercise (low-dose), or 300 min/wk of moderate-intensity aerobic exercise (high-dose). Inflammation outcomes included high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL6), and soluble tumor …

Summary; Autologous reconstruction accounts for nearly one-quarter of all breast reconstruction cases in the United States, with the abdomen functioning as the most popular donor site. This case describes a 62-year-old woman who presented to our clinic with a remote history of estrogen receptor+/progesterone+ breast cancer and bilateral implant-based reconstruction. After grade IV capsular contracture of her left breast, she presented for autologous reconstruction. Due to her body habitus and prior belt lipectomy, deep inferior epigastric perforator flap reconstruction was contra-indicated. The thoracodorsal artery perforator (TDAP) flap is well described in the literature, and was chosen as an alternative salvage …

Preclinical studies: have demonstrated a complex cross-talk between Notch and estrogen signaling in ERα-positive breast cancer. Gamma-secretase inhibitors (GSIs) are investigational agents that block the cleavage and activation of Notch receptors. In animal models of endocrine-resistant breast cancer, combinations of tamoxifen and GSIs produce additive or synergistic efficacy, while decreasing the intestinal toxicity of GSIs. However, results of a clinical trial of a GSI-endocrine therapy combination in the metastatic setting have not been published to date, nor had the safety of such combinations been investigated with longer term treatment. We conducted a phase 1b dose escalation trial (NCT01149356) of GSI …

Background: In recent years, palliative care utilization has been increasing while life-sustaining/local procedures have been declining at the end of life. Palliative care utilization widely varies based on tumor type. Limited information is available on inpatient palliative care in colorectal cancer. Aims: This study investigated inpatient palliative care utilization and its association with patient demographics, hospital charges, and procedures among colorectal cancer patients admitted to US hospitals between 2008 and 2017. Receipt of life-sustaining and local procedures and surgeries were also investigated during the ten years. Methods: Data were extracted from the National inpatient sample (NIS) database containing de-identified information …


Geographic And Intra-Racial Disparities In Early-Onset Colorectal Cancer In The Seer 18 Registries Of The United States, Wesal H. Abualkhair, Meijiao Zhou, Carolina O. Ochoa, Leonel Lacayo, Caitlin Murphy, Xiao Cheng Wu, Jordan J. Karlitz Oct 2020

Geographic And Intra-Racial Disparities In Early-Onset Colorectal Cancer In The Seer 18 Registries Of The United States, Wesal H. Abualkhair, Meijiao Zhou, Carolina O. Ochoa, Leonel Lacayo, Caitlin Murphy, Xiao Cheng Wu, Jordan J. Karlitz

Background: Although early-onset colorectal cancer (EOCRC) incidence rates (IRs) are increasing, geographic and intra-racial IR disparities are not well defined. Methods: 2000-2015 Surveillance, Epidemiology, and End Results (SEER) program CRC IR Analysis (170,434 cases) was performed from ages 30 to 60 in four US regions, 18 individual registries, metropolitan and nonmetropolitan locations and stratified by race. Analyses were conducted in 1-year and 5-year age increments. Results: Wide US regional EOCRC IR variations exist: For example, age 45 IRs in the south are 26.8/100,000, 36.0% higher than the West, 19.7/100,000 (p < 0.0001). Disparities magnify between individual registries: EOCRC IRs in highest risk registries were 177-348% (Alaska Natives), 75-200% (Hawaii), 76-128% (Louisiana), and 61-125% (Kentucky) higher than lowest risk registries depending on age. EOCRC IRs are 18.2%-25.6% higher in nonmetropolitan versus metropolitan settings. Wide geographic intra-racial disparities exist. Within the White population, the greatest IR difference (78.8%) was between Kentucky (5.9/100,000) and Los Angeles (3.3/100,000) in 30- to 34-year-olds (p <.0001). Within the Black population, the greatest difference (136.2%) was between rural Georgia (30.7/100,000) and California excluding San Francisco-Oakland/San Jose-Monterey/Los Angeles (13/100,000) in 40- to 44-year-olds (p = 0003). Conclusion: Marked geographic EOCRC disparities exist with disproportionately high IRs in Alaska Natives, Hawaii, and southern registries. Geographic intra-racial disparities are present within White and Black populations. In Blacks, there are disproportionately high EOCRC IRs in rural Georgia. Although vigilance is required in all populations, attention must be paid to these higher risk populations. Potential interventions include assuring early investigation of symptoms, targeting modifiable risk factors and utilizing earlier age 45 screening options supported by some guidelines.

Alveolar rhabdomyosarcoma (ARMS) is characterized by one of three translocation states: t(2;13) (q35;q14) producing PAX3-FOXO1, t(1;13) (p36;q14) producing PAX7-FOXO1, or translocation-negative. Tumors with t(2;13) are associated with greater disease severity and mortality than t(1;13) positive or translocation negative patients. Consistent with this fact, previous work concluded that a molecular analysis of RMS translocation status is essential for the accurate determination of prognosis and diagnosis. However, despite this knowledge, most diagnoses rely on histology and in some cases utilize fluorescence in situ hybridization (FISH) probes unable to differentiate between translocation products. Along these same lines, diagnostic RT-PCR analysis, which can differentiate …

BACKGROUND: Breast cancer is the second leading cause of cancer deaths in the USA. Triple-negative breast cancer (TNBC) is a clinically aggressive subtype of breast cancer with high rates of metastasis, tumor recurrence, and resistance to therapeutics. Obesity, defined by a high body mass index (BMI), is an established risk factor for breast cancer. Women with a high BMI have increased incidence and mortality of breast cancer; however, the mechanisms(s) by which obesity promotes tumor progression are not well understood. METHODS: In this study, obesity-altered adipose stem cells (obASCs) were used to evaluate obesity-mediated effects of TNBC. Both in vitro …

Triple negative breast cancer (TNBC) patients have high risk of recurrence and metastasis, and current treatment options remain limited. Cancer stem-like cells (CSCs) have been linked to cancer initiation, progression and chemotherapy resistance. Notch signaling is a key pathway regulating TNBC CSC survival. Treatment of TNBC with PI3K or mTORC1/2 inhibitors results in drug-resistant, Notch-dependent CSC. However, downstream mechanisms and potentially druggable Notch effectors in TNBC CSCs are largely unknown. We studied the role of the AKT pathway and mitochondrial metabolism downstream of Notch signaling in TNBC CSC from cell lines representative of different TNBC molecular subtypes as well as …
