Proteomics-Based Approach For Detailing The Allergenic Profile Of Cannabis Chemotypes, Cali Loblundo, Jenna Severa, Gabrielle A Peruggia, Kristina Reid Black, Suman Chandra, Hemant Lata, Mahmoud Elsohly, Martin D Chapman, Deepak A. Deshpande, Ajay P. Nayak

Center for Translational Medicine Faculty Papers

Allergic sensitization to cannabis is an emerging public health concern and is difficult to clinically establish owing to lack of standardized diagnostic approaches. Attempts to develop diagnostic tools were largely hampered by the Schedule I restrictions on cannabis, which limited accessibility for research. Recently, however, hemp was removed from the classified list, and increased accessibility to hemp allows for the evaluation of its practical clinical value for allergy diagnosis. We hypothesized that the proteomic profile is preserved across different cannabis chemotypes and that hemp would be an ideal source of plant material for clinical testing. Using a proteomics-based approach, we …

Isolated Cerebral Mucormycosis And Aspergillosis Coinfection In An Immunocompromised Adult, George Sun, Allison Weiss, Joy Zhao, Mitchell Silver, Michael Demaio, Sara Dehbashi

Department of Neurology Faculty Papers

Opportunistic fungal infections are a major cause of mortality in immunosuppressed patients, with mucormycosis and aspergillosis as two of the most commonly identified fungal organisms. Coinfection with mucormycosis and aspergillosis is rare, but cases have been reported in literature, most commonly presenting as disseminated invasive fungal infection with cerebrorhino-orbital involvement in an immunocompromised patient. Infections are most commonly caused by direct implantation of spores with localised angioinvasion. Haematogenous spread is rare, with most cases secondary to haematological malignancies or intravenous drug use. Coinfection with mucormycosis and aspergillosis portends a poor prognosis, with a high mortality rate. Thus, prompt recognition and …

Extracellular Trna-Derived Rnas As Emerging Activators Of Endosomal Toll-Like Receptors: A Narrative Review, Justin Gumas, Yohei Kirino

Computational Medicine Center Faculty Papers

Background and Objective: The innate immune system deploys various pattern-recognition receptors (PRRs), including Toll-like receptors (TLRs), to detect the invasion of pathogens and initiate protective responses. TLR7 and TLR8 are located within the endosome of immune cells and are activated by single-stranded RNAs (ssRNAs). In addition to foreign ssRNAs from bacteria and viruses, endogenous self-ssRNAs, such as microRNAs (miRNAs), have been shown to activate TLR7 and TLR8, but such endogenous ssRNA ligands have not yet been fully elucidated. This scientific knowledge gap is partly derived from the technical limitations of standard RNA-seq, particularly its inability to capture non-miRNA-short non-coding RNAs …

A Case Presentation Of Pericarditis Associated With Haemophilus Influenzae Bacteremia, Risa Goldberg, Md, Harrison Bell, Md

The Medicine Forum

Acute pericarditis, or inflammation of the pericardial sac, is a clinical condition which can often be attributed to a variety of underlying etiologies, including infection, autoimmune disease, trauma, and malignancy. While viral infections are commonly implicated in the etiology of pericarditis, bacteria known to be associated with pericarditis include staphylococcus species, streptococcal species, tuberculosis, and in children, Haemophilus influenzae.¹ Here we present a rare case of pericarditis in an adult male patient which occurred in association with Haemophilus influenzae bacteremia.

A Case Of Bartonella Endocarditis And Torrential Aortic Regurgitation Leading To Cardiac Arrest, Brandon Pecchia, Md, Ms, Sawyer Kieffer, Md

The Medicine Forum

Infective endocarditis can be difficult to diagnose, especially when blood culture-negative. We describe a case of a patient who presented with signs and symptoms of new, acute decompensated heart failure who was found to have culture-negative endocarditis, a large, mobile aortic valve mass, and torrential aortic regurgitation. Although the patient remained clinically stable during early admission and was planned for surgical correction of the valvular pathology, he suffered abrupt clinical decompensation which resulted in cardiac arrest. Postmortem serologies were found to be positive for Bartonella henselae and Bartonella quintana.

BACKGROUND: The prevalence, incidence, and interrelationships of persistent symptoms after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection vary. There are limited data on specific phenotypes of persistent symptoms. Using latent class analysis (LCA) modeling, we sought to identify whether specific phenotypes of COVID-19 were present 3 months and 6 months post-infection.

METHODS: This was a multicenter study of symptomatic adults tested for SARS-CoV-2 with prospectively collected data on general symptoms and fatigue-related symptoms up to 6 months postdiagnosis. Using LCA, we identified symptomatically homogenous groups among COVID-positive and COVID-negative participants at each time period for both general and fatigue-related …

Enough Is Enough: Salvage Procedures In Severe Periprosthetic Joint Infection, Yves Gramlich, Javad Parvizi

Rothman Institute Papers

Background

In severe cases of periprosthetic joint infection involving negative host-dependent factors, individual-based decisions between a curative therapy vs. salvage procedure are necessary. We aimed to review salvage procedures in severe periprosthetic joint infection cases, where a gold standard of a curative two-stage exchange can no longer be achieved. The options of knee arthrodesis, amputation, persistent fistula (stable drainage), or a debridement, antibiotics, and implant retention procedure in late-onset cases are discussed, including lifelong antibiotic suppression alone.

Methods

We focused on known salvage procedures for severe periprosthetic joint infection of the hip and knee, such as amputation, arthrodesis, antibiotic …

Primary liver cancer is a rising cause of cancer deaths in the US. Although immunotherapy with immune checkpoint inhibitors induces a potent response in a subset of patients, response rates vary among individuals. Predicting which patients will respond to immune checkpoint inhibitors is of great interest in the field. In a retrospective arm of the National Cancer Institute Cancers of the Liver: Accelerating Research of Immunotherapy by a Transdisciplinary Network (NCI-CLARITY) study, we use archived formalin-fixed, paraffin-embedded samples to profile the transcriptome and genomic alterations among 86 hepatocellular carcinoma and cholangiocarcinoma patients prior to and following immune checkpoint inhibitor treatment. …

Diagnosis Of Periprosthetic Joint Infection: The Utility Of Biomarkers In 2023, Mehmet Kursat Yilmaz, Ahmad Abbaszadeh, Saad Tarabichi, Ibrahim Azboy, Javad Parvizi

Rothman Institute Papers

Periprosthetic joint infection (PJI) is a rare yet devastating complication following total joint arthroplasty (TJA). Early and accurate diagnosis of PJI is paramount in order to maximize the chances of successful treatment. However, we are yet to identify a single “gold standard” test for the diagnosis of PJI. As a result, the diagnosis of PJI is often challenging. Currently, the 2018 ICM definition of PJI is the only validated diagnostic criteria available. This article will review the importance of serum and synovial biomarkers in the diagnosis of PJI. In addition, it will provide a brief overview of the emerging modalities …

Apoe4, Age, And Sex Regulate Respiratory Plasticity Elicited By Acute Intermittent Hypercapnic-Hypoxia, Jayakrishnan Nair, Joseph F. Welch, Alexandria B. Marciante, Tingting Hou, Qing Lu, Emily J. Fox, Gordon S. Mitchell

Department of Physical Therapy Faculty Papers

Rational

Acute intermittent hypoxia (AIH) shows promise for enhancing motor recovery in chronic spinal cord injuries and neurodegenerative diseases. However, human trials of AIH have reported significant variability in individual responses.

Objectives

Identify individual factors (eg, genetics, age, and sex) that determine response magnitude of healthy adults to an optimized AIH protocol, acute intermittent hypercapnic-hypoxia (AIHH).

Methods

In 17 healthy individuals (age = 27 ± 5 yr), associations between individual factors and changes in the magnitude of AIHH (15, 1-min O2 = 9.5%, CO2 = 5% episodes) induced changes in diaphragm motor-evoked potential (MEP) amplitude and inspiratory mouth occlusion pressures …

BACKGROUND: Lower-extremity endovascular revascularization (LER) is often required for diabetic patients with chronic limb threatening ischemia (CLTI). During the post-revascularization period patients may unpredictably experience major adverse cardiac events (MACE) and major adverse limb events (MALE). Several families of cytokines are involved in the inflammatory process that underlies the progression of atherosclerosis. According to current evidence, we have identified a panel of possible biomarkers related with the risk of developing MACE and MALE after LER. The aim was to study the relationship between a panel of biomarkers - Interleukin-1 (IL-1) and 6 (IL-6), C-Reactive Protein (CRP), Tumor Necrosis Factor-α (TNF-α), …

Test-Retest Reliability Of Virtual Reality Devices In Quantifying For Relative Afferent Pupillary Defect, Prithul Sarker, Nasif Zaman, Joshua Ong, Phani Paladugu, Molly Aldred, Ethan Waisberg, Andrew G. Lee, Alireza Tavakkoli

Student Papers, Posters & Projects

Background: The swinging flashlight test (SFT) is one of the most prominent clinical tests for detecting the relative afferent pupillary defect (RAPD). A positive RAPD localizes the lesion to the affected afferent pupil pathway and is a critical part of any ophthalmic exam. Testing for an RAPD, however, can be challenging (especially when small), and there is significant intrarater and interrater variability.

Methods: Prior studies have shown that the pupillometer can improve the detection and measurement of RAPD. In our previous research, we have demonstrated an automatic SFT by utilizing virtual reality (VR), named VR-SFT. We applied our methods to …

Gp38 As A Vaccine Target For Crimean-Congo Hemorrhagic Fever Virus, Gabrielle Scher, Dennis A. Bente, Megan C. Mears, Maria N.B. Cajimat, Matthias J. Schnell

Department of Microbiology and Immunology Faculty Papers

Crimean-Congo Hemorrhagic Fever Virus (CCHFV) is a tick-borne virus that causes severe hemorrhagic disease in humans. There is a great need for effective vaccines and therapeutics against CCHFV for humans, as none are currently internationally approved. Recently, a monoclonal antibody against the GP38 glycoprotein protected mice against lethal CCHFV challenge. To show that GP38 is required and sufficient for protection against CCHFV, we used three inactivated rhabdoviral-based CCHFV-M vaccines, with or without GP38 in the presence or absence of the other CCHFV glycoproteins. All three vaccines elicited strong antibody responses against the respective CCHFV glycoproteins. However, only vaccines containing GP38 …

Schaeffer

Einstein Health Papers

Introduction Approximately one million prostate biopsies are performed annually in the USA, and most are performed using a transrectal approach under local anaesthesia. The risk of postbiopsy infection is increasing due to increasing antibiotic resistance of rectal flora. Single-centre studies suggest that a clean, percutaneous transperineal approach to prostate biopsy may have a lower risk of infection. To date, there is no high-level evidence comparing transperineal versus transrectal prostate biopsy. We hypothesise that transperineal versus transrectal prostate biopsy under local anaesthesia has a significantly lower risk of infection, similar pain/discomfort levels and comparable detection of non-low-grade prostate cancer.

Department of Medicine Faculty Papers

Progression of disease within 24 months (POD24) from diagnosis in marginal zone lymphoma (MZL) was shown to portend poor outcomes in prior studies. However, many patients with MZL do not require immediate therapy, and the time from diagnosis-to-treatment interval can be highly variable with no universal criteria to initiate systemic therapy. Hence, we sought to evaluate the prognostic relevance of early relapse or progression within 24 months from systemic therapy initiation in a large US cohort. The primary objective was to evaluate the overall survival (OS) in the two groups. The secondary objective included the evaluation of factors predictive of …

A Rare Case Of Autopsy Proven Achromobacter Xylosoxidans Endocarditis Involving Tricuspid Valve: A Case Report, Chaitra Janga, Mackenzie Kramer, Ifrah Naeem, Lucy Checchio, Md, Zahra Qamar

Abington Jefferson Health Papers

Infective endocarditis refers to infection of one or more valves of the heart, with Achromobacter xylosoxidans (A. xylosoxidans) being a rare cause. So far, 24 cases of A. xylosoxidans endocarditis were reported, with only one case describing tricuspid valvular involvement. Despite the rarity of A. xylosoxidans endocarditis, it is important for clinicians to be aware of atypical presentation and the high mortality associated with it. We present an autopsy-proven case of tricuspid valve endocarditis in the setting of A. xylosoxidans bacteremia in a 43-year-old female.
