2019 EULAR/ACR classification criteria for SLE score predicts future lupus hospital admission and costs.

Objective: To test the ability of the 2019 EULAR/ACR Classification Criteria for SLE score to predict lupus related hospitalization and overall cost of hospitalization.

Methods: 217 University of Kentucky patient records that met our preliminary inclusion criteria, 44 patients were selected by a random number generator algorithm for a thorough chart review to collect data needed for calculation of the 2019 EULAR/ACR Classification Criteria for SLE score. Total hospitalization cost was calculated by using hospital adjusted expenses per inpatient day data, which estimates the expense incurred by the hospital to provide services and thus removes the variability of charges and reimbursements introduced by insurance type.

A case series of hydroxychloroquine exacerbating the dermatomyositis rash.

Hydroxychloroquine (HCQ) is an antimalarial agent that is commonly used in the management of rheumatic skin disease. Few reports exist documenting exacerbation of dermatomyositis (DM) related to HCQ. Herein, we describe three adult patients with worsening DM cutaneous disease after starting HCQ and resolution or improvement with cessation.

Iatrogenic ANA: An emerging source of expensive diagnostic confusion.

Intravenous immune globulin (IVIg) therapy has been shown to be useful in a multitude of disorders. IVIg is produced from pooled human plasma; therefore, autoantibodies found in the general population are also present in IVIg and transferred to those being transfused. This can prove a particular hazard for screening and diagnostic tests based on autoantibodies.

Utilizing Chamber Music to Teach Non-Verbal Communication to Medical Students: A Pilot Initiative.

Introduction The importance of non-verbal cues in communication between physicians and patients is well published in the medical literature. However, few medical school curricula teach non-verbal communication. Chamber musicians employ non-verbal communication to coordinate musician intention.

Rapidly Progressive Acute Liver Failure in Relapsed Multiple Myeloma.

Multiple myeloma affects upwards of 30,000 people every year and has significant morbidity and mortality. Common complications of the disease involve lytic bone lesions, hypercalcemia, anemia, and acute renal failure. A rare, yet serious, complication includes acute liver failure secondary to hepatic plasma cell infiltration.

Antecedent immunosuppressive therapy for immune-mediated inflammatory diseases in the setting of a COVID-19 outbreak.

Background: Finite clinical data and understanding of COVID-19 immunopathology has led to limited, opinion-based recommendations for the management of patients with immune-mediated inflammatory disease (IMID) receiving immunosuppressive (IS) therapeutics.

Objective: To determine if IS therapeutic type affects COVID-19 risk among patients with IMID.

Methods: We conducted a retrospective cohort analysis of Henry Ford Health System patients tested for COVID-19 between February 1 and April 18, 2020, treated with IS medication for IMID.

Barriers, beliefs, and practices regarding hygiene and vaccination among the homeless during a hepatitis A outbreak in Detroit, MI.

Appropriate hygiene practices and vaccine acceptance are key factors impacting the health of homeless individuals. A recent outbreak of hepatitis A in Michigan, especially impacting Detroit, prompted us to investigate the practices and attitudes of Detroit's homeless population toward hygiene measures and vaccinations, as well as barriers to such resources. We developed a questionnaire as a means to collect our data, and participants were interviewed at shelters and soup kitchens.

Clinical Characterization of Host Response to Simian Hemorrhagic Fever Virus Infection in Permissive and Refractory Hosts: A Model for Determining Mechanisms of VHF Pathogenesis.

Simian hemorrhagic fever virus (SHFV) causes a fulminant and typically lethal viral hemorrhagic fever (VHF) in macaques (Cercopithecinae: spp.) but causes subclinical infections in patas monkeys (Cercopithecinae: ). This difference in disease course offers a unique opportunity to compare host responses to infection by a VHF-causing virus in biologically similar susceptible and refractory animals.

Subclinical Infection of Macaques and Baboons with A Baboon Simarterivirus.

Simarteriviruses (: ) are commonly found at high titers in the blood of African monkeys but do not cause overt disease in these hosts. In contrast, simarteriviruses cause severe disease in Asian macaques upon accidental or experimental transmission. Here, we sought to better understand the host-dependent drivers of simarterivirus pathogenesis by infecting olive baboons (n = 4) and rhesus monkeys (n = 4) with the simarterivirus Southwest baboon virus 1 (SWBV-1).

Antibody responses to Zika virus proteins in pregnant and non-pregnant macaques.

The specificity of the antibody response against Zika virus (ZIKV) is not well-characterized. This is due, in part, to the antigenic similarity between ZIKV and closely related dengue virus (DENV) serotypes. Since these and other similar viruses co-circulate, are spread by the same mosquito species, and can cause similar acute clinical syndromes, it is difficult to disentangle ZIKV-specific antibody responses from responses to closely-related arboviruses in humans.

Pegivirus avoids immune recognition but does not attenuate acute-phase disease in a macaque model of HIV infection.

Human pegivirus (HPgV) protects HIV+ people from HIV-associated disease, but the mechanism of this protective effect remains poorly understood. We sequentially infected cynomolgus macaques with simian pegivirus (SPgV) and simian immunodeficiency virus (SIV) to model HIV+HPgV co-infection. SPgV had no effect on acute-phase SIV pathogenesis-as measured by SIV viral load, CD4+ T cell destruction, immune activation, or adaptive immune responses-suggesting that HPgV's protective effect is exerted primarily during the chronic phase of HIV infection.

Oropharyngeal mucosal transmission of Zika virus in rhesus macaques.

Zika virus is present in urine, saliva, tears, and breast milk, but the transmission risk associated with these body fluids is currently unknown. Here we evaluate the risk of Zika virus transmission through mucosal contact in rhesus macaques. Application of high-dose Zika virus directly to the tonsils of three rhesus macaques results in detectable plasma viremia in all animals by 2 days post-exposure; virus replication kinetics are similar to those observed in animals infected subcutaneously.

Genome Sequence of a Novel Kunsagivirus (: ) from a Wild Baboon ().

The picornaviral genus has a single member, kunsagivirus A, which was discovered in migratory bird feces. We report here the discovery of a novel kunsagivirus in wild yellow baboon () blood. The genomic sequence of this virus indicates the probable need for the establishment of a second kunsagivirus species.

Seroprevalence of Zika Virus in Wild African Green Monkeys and Baboons.

Zika virus (ZIKV) has recently spread through the Americas and has been associated with a range of health effects, including birth defects in children born to women infected during pregnancy. Although the natural reservoir of ZIKV remains poorly defined, the virus was first identified in a captive "sentinel" macaque monkey in Africa in 1947. However, the virus has not been reported in humans or nonhuman primates (NHPs) in Africa outside Gabon in over a decade.

Microbial Translocation and Inflammation Occur in Hyperacute Immunodeficiency Virus Infection and Compromise Host Control of Virus Replication.

Within the first three weeks of human immunodeficiency virus (HIV) infection, virus replication peaks in peripheral blood. Despite the critical, causal role of virus replication in determining transmissibility and kinetics of progression to acquired immune deficiency syndrome (AIDS), there is limited understanding of the conditions required to transform the small localized transmitted founder virus population into a large and heterogeneous systemic infection. Here we show that during the hyperacute "pre-peak" phase of simian immunodeficiency virus (SIV) infection in macaques, high levels of microbial DNA transiently translocate into peripheral blood.

Heterologous Protection against Asian Zika Virus Challenge in Rhesus Macaques.

Background: Zika virus (ZIKV; Flaviviridae, Flavivirus) was declared a public health emergency of international concern by the World Health Organization (WHO) in February 2016, because of the evidence linking infection with ZIKV to neurological complications, such as Guillain-Barre Syndrome in adults and congenital birth defects including microcephaly in the developing fetus. Because development of a ZIKV vaccine is a top research priority and because the genetic and antigenic variability of many RNA viruses limits the effectiveness of vaccines, assessing whether immunity elicited against one ZIKV strain is sufficient to confer broad protection against all ZIKV strains is critical. Recently, in vitro studies demonstrated that ZIKV likely circulates as a single serotype.

In vivo characterization of the physicochemical properties of polymer-linked TLR agonists that enhance vaccine immunogenicity.

The efficacy of vaccine adjuvants such as Toll-like receptor agonists (TLRa) can be improved through formulation and delivery approaches. Here, we attached small molecule TLR-7/8a to polymer scaffolds (polymer-TLR-7/8a) and evaluated how different physicochemical properties of the TLR-7/8a and polymer carrier influenced the location, magnitude and duration of innate immune activation in vivo. Particle formation by polymer-TLR-7/8a was the most important factor for restricting adjuvant distribution and prolonging activity in draining lymph nodes.
