Ambulatory and Primary Care Articles

BACKGROUND & AIMS: The Global Leadership Initiative on Malnutrition (GLIM) approach to malnutrition diagnosis is based on assessment of three phenotypic (weight loss, low body mass index, and reduced skeletal muscle mass) and two etiologic (reduced food intake/assimilation and disease burden/inflammation) criteria, with diagnosis confirmed by fulfillment of any combination of at least one phenotypic and at least one etiologic criterion. The original GLIM description provided limited guidance regarding assessment of inflammation and this has been a factor impeding further implementation of the GLIM criteria. We now seek to provide practical guidance for assessment of inflammation in support of the …

Faculty, Staff and Student Publications

Spontaneous idiopathic vulvar edema during the second trimester is a rare condition. The approach to managing this condition involves relieving symptoms, identifying underlying causes, and implementing appropriate treatment. Managing such cases during pregnancy is challenging because of concerns for potential adverse fetal outcomes. Conservative management expects the condition to be relieved spontaneously postpartum, whereas invasive treatment offers a more rapid resolution. Treatment choices are controversial because each method has its pros and cons and influences the delivery process to a certain extent. Surgical drainage becomes a viable option when patients are not responsive to medications. We report a case of …

Journal of Mind and Medical Sciences

Despite continuous investigations in the diagnosis and treatment of severe acute pancreatitis (SAP), this disease still remains a critical condition with a mortality rate of up to 35%. The pathophysiology of SAP involves an important inflammatory reaction of the pancreas (mediated by inflammatory cytokines and immune system activation), causing severe local tissue damage as well as important systemic imbalances. IL-17 is an inflammatory mediator that have a pivotal role in SAP evolution, generating multiple interactions between inflammatory cytokines and significantly influencing the immune system response. Consequently, continuous renal replacement therapy/CRRT was added to the conventional therapy, leading to improved treatment …

Methods: An anonymous, online, cross-sectional survey of physicians was distributed to resident and faculty physicians in …

A Matter Of Time: How Musical Training Affects Time Perception, Jahanvi Mittal, Khushi Kaur Juneja, Saumya Saumya, Anuj Shukla

Faculty, Staff and Student Publications

Musical training has been linked to changes in early attentional and perceptual processing. Thus, such an altered attentional and perceptual processing has enabled musicians to judge the duration differently than non-musicians. Although these claims seem intriguing, there are many questions that are not addressed yet, for example, how would the performance of musically-trained differ from that of untrained on visual and auditory temporal judgments? Is there any advantage to musically-trained person in temporal processing? To understand these questions, we thus conducted a series of Auditory and Visual Temporal Bisection Tasks on 32 musically-trained and 32 musically-untrained participants. We hypothesized that …

Role Of Ectopic Olfactory Receptors In The Regulation Of The Cardiovascular-Kidney-Metabolic Axis, Mitchell R Beito, Sadia Ashraf, Dorcas Odogwu, Romain Harmancey

Faculty, Staff and Student Publications

Olfactory receptors (ORs) represent one of the largest yet least investigated families of G protein-coupled receptors in mammals. While initially believed to be functionally restricted to the detection and integration of odors at the olfactory epithelium, accumulating evidence points to a critical role for ectopically expressed ORs in the regulation of cellular homeostasis in extranasal tissues. This review aims to summarize the current state of knowledge on the expression and physiological functions of ectopic ORs in the cardiovascular system, kidneys, and primary metabolic organs and emphasizes how altered ectopic OR signaling in those tissues may impact cardiovascular-kidney-metabolic health.

Topographical And Cell Type-Specific Connectivity Of Rostral And Caudal Forelimb Corticospinal Neuron Populations, Lina Marcela Carmona, Eric D Thomas, Kimberly Smith, Bosiljka Tasic, Rui M Costa, Anders Nelson

Faculty, Staff and Student Publications

Corticospinal neurons (CSNs) synapse directly on spinal neurons, a diverse assortment of cells with unique structural and functional properties necessary for body movements. CSNs modulating forelimb behavior fractionate into caudal forelimb area (CFA) and rostral forelimb area (RFA) motor cortical populations. Despite their prominence, the full diversity of spinal neurons targeted by CFA and RFA CSNs is uncharted. Here, we use anatomical and RNA sequencing methods to show that CSNs synapse onto a remarkably selective group of spinal cell types, favoring inhibitory populations that regulate motoneuron activity and gate sensory feedback. CFA and RFA CSNs target similar spinal neuron types, …

School of Medicine Faculty Publications

Objectives: Sepsis is one of the most common, costly, and misdiagnosed conditions in U.S. emergency departments (EDs). ED providers often treat on nonspecific signs, subjective suspicion, or presumption of infection, resulting in over- and undertreatment. An increased understanding of host response has opened a new direction for sepsis diagnostics. The IntelliSep test is a U.S. Food and Drug Administration–cleared cellular host response diagnostic that could help distinguish sepsis in ED settings. Our objective was to evaluate the potential of the cellular host response test to expedite appropriate care for patients who present with signs of infection. Methods: We performed a …

Strategies For Combating Vaccine Hesitancy In Primary Care, Elizabeth Perkins Hayes

Student Scholar Showcase

This article will summarize methods for providers to effectively combat vaccine hesitancy in their patient populations. Vaccine hesitancy is a growing concern in the medical field, as new cases of vaccine preventable diseases arise. However, vaccine hesitancy is more common than vaccine resistance and can be converted into vaccine acceptance with effective communication strategies.

There is no easy solution to the complex problem of vaccine hesitancy. Most studies demonstrate that effective conversion to vaccine acceptance requires tailoring vaccine information to the patient and listening to their concerns. Other methods include exposing patients to survivors of vaccine preventable diseases, or using …

When Educational Images Don’T Reflect The Population: Phlegmasia Cerulea Dolens, A Case Report, Kasha Bornstein, Elizabeth Larosa, Kelsey Byrd, Dan Laney, Hector Ferral, Heather Murphy-Lavoie

School of Medicine Faculty Publications

Introduction: Phlegmasia cerulea dolens (PCD) is an uncommon, potentially life-threatening complication of acute deep venous thromboses that requires a timely diagnosis. The name of the condition, the visual diagnostic criteria, and the preponderance of cases in the literature referencing findings exclusively in patients with lighter skin complexions means that PCD may not be on the differential diagnosis for the patient with more melanated skin who is experiencing this time-sensitive vascular emergency. Case Report: We describe one case of PCD in a patient with darker skin complexion and the importance of identifying clinical findings, regardless of skin color, given the paucity …

The gut microbiota has been found to play an important role in the progression of metabolic dysfunction-associated steatohepatitis (MASH), but the mechanisms have not been established. Here, by developing a click-chemistry-based enrichment strategy, we identified several microbial-derived bile acids, including the previously uncharacterized 3-succinylated cholic acid (3-sucCA), which is negatively correlated with liver damage in patients with liver-tissue-biopsy-proven metabolic dysfunction-associated fatty liver disease (MAFLD). By screening human bacterial isolates, we identified Bacteroides uniformis strains as effective producers of 3-sucCA both in vitro and in vivo. By activity-based protein purification and identification, we identified an enzyme annotated as β-lactamase in B. …

The rapid evolution of SARS-CoV-2 is driven in part by a need to evade the antibody response in the face of high levels of immunity. Here, we isolate spike (S) binding monoclonal antibodies (mAbs) from vaccinees who suffered vaccine break-through infections with Omicron sub lineages BA.4 or BA.5. Twenty eight potent antibodies are isolated and characterised functionally, and in some cases structurally. Since the emergence of BA.4/5, SARS-CoV-2 has continued to accrue mutations in the S protein, to understand this we characterize neutralization of a large panel of variants and demonstrate a steady attrition of neutralization by the panel of …
