Neuroinvasive West Nile Virus Infection in Immunosuppressed and Immunocompetent Adults.

Importance: West Nile virus (WNV) is the leading cause of human arboviral disease in the US, peaking during summer. The incidence of WNV, including its neuroinvasive form (NWNV), is increasing, largely due to the expanding distribution of its vector, the Culex mosquito, and climatic changes causing heavy monsoon rains. However, the distinct characteristics and outcomes of NWNV in individuals who are immunosuppressed (IS) and individuals who are not IS remain underexplored.

A Rare Case of Septic Ovarian Thrombophlebitis Caused by Tissierella praeacuta.

We report a case of bacteremia and septic thrombophlebitis of the ovarian vein as a rare puerperal complication in a young patient. She was successfully managed with subcutaneous low molecular weight heparin (LMWH) and intravenous (IV) antibiotics before transitioning to a prolonged course of oral antibiotics at discharge.

Infections and antimicrobial prescribing in patients hospitalized with coronavirus disease 2019 (COVID-19) during the first pandemic wave.

Objective: To evaluate the rate of coinfections and secondary infections seen in hospitalized patients with COVID-19 and antimicrobial prescribing patterns.

Methods: This single-center, retrospective study included all patients aged ≥18 years admitted with COVID-19 for at least 24 hours to a 280-bed, academic, tertiary-care hospital between March 1, 2020, and August 31, 2020. Coinfections, secondary infections, and antimicrobials prescribed for these patients were collected.

Neuroinvasive West Nile virus infection in solid organ transplant recipients.

Background: Literature on the natural course of neuroinvasive West Nile virus (WNV) infection in solid organ transplant (SOT) recipients is sparse. In the setting of a 2021 WNV outbreak in Arizona, we reviewed our institution's experience with neuroinvasive WNV infection in patients with SOT.

Methods: We retrospectively identified SOT recipients treated for neuroinvasive WNV at Mayo Clinic in Arizona from 2007 through 2021.

The use of Vaccinia Immune Globulin in the Treatment of Severe Mpox. Virus Infection in Human Immunodeficiency Virus/AIDS.

We report a case of progressive, severe mpox virus (MPXV) infection in a patient with AIDS despite a standard course of tecovirimat. He significantly improved after administration of vaccinia immune globulin intravenous (VIGIV) highlighting its use as an adjunct for severe disease in immunocompromised hosts.

Superimposed Neuroinvasive Coccidioidomycosis and West Nile Virus Infection.

A 58-year-old man with recently diagnosed coccidioidal meningitis presented to the ED with a five-day history of headache, photopsia, blurred vision, and worsening encephalopathy. His coccidioidal meningitis had responded well to fluconazole therapy, but three weeks later, he developed acute symptomatic worsening. Unfortunately, his clinical worsening coincided with Arizona's worst seasonal West Nile Virus (WNV) outbreak.

Cerebral abscess with as a complication of pelvic inflammatory disease in the setting of intrauterine device use.

A 43-year-old healthy female with no significant medical problems except for recently diagnosed pelvic inflammatory disease presented to our hospital with acute onset, severe head and neck pain. Brain imaging revealed a rim-enhancing lesion consistent with an abscess. The patient underwent successful surgical removal of the abscess and its capsule.

Pulmonary Coccidioidomycosis.

Coccidioidomycosis is an infection caused by the geographically restricted dimorphic fungus, . Coccidioidomycosis occurs endemically in the southwestern and western United States, mainly in focused regions of Arizona and California where the incidence is highest, and in Central and South America. Patients with impaired immunity, especially those with impaired cellular immunity, are at higher risk of severe and disseminated disease.

Is It Actionable? An Evaluation of the Rapid PCR-Based Blood Culture Identification Panel on the Management of Gram-Positive and Gram-Negative Blood Stream Infections.

Background: There is growing interest in the use of rapid blood culture identification (BCID) in antimicrobial stewardship programs (ASPs). Although many studies have looked at its clinical and economic utility, its comparative utility in gram-positive and gram-negative blood stream infections (BSIs) has not been as well characterized.

Methods: The study was a quasi-experimental retrospective study at the Mayo Clinic in Phoenix, Arizona.

Knowledge and Attitudes about HIV/AIDS in Illegal Residents in the Kingdom of Saudi Arabia.

Objectives: To study the knowledge, attitudes, and practices with regard to human immunodeficiency virus infection / acquired immune deficiency syndrome (HIV/AIDS) in illegal residents, in the Kingdom of Saudi Arabia (KSA).

Materials And Methods: A questionnaire study was conducted among the illegal residents from four regions in Saudi Arabia: Jeddah, Makkah, Riyadh, and Jazan.

Results: The survey enrolled 5,000 participants, 79%male (39.
