Article Synopsis
  • EvalMpox is a clinical decision support system designed to identify patients with rash who may be under investigation for mpox and suggest testing for them.
  • Out of 668 patients assessed, the system's recommendation for testing showed a positive predictive value of 35%, meaning 35% of those tested actually had a positive mpox result.
  • It also had a high negative predictive value of 99%, indicating that 99% of patients who did not test positive were accurately identified as not having mpox.

Monkeypox virus was historically rare outside of West and Central Africa until the current 2022 global outbreak, which has required clinicians to be alert to identify individuals with possible monkeypox, institute isolation, and take appropriate next steps in evaluation and management. Clinical decision support systems (CDSS), which have been shown to improve adherence to clinical guidelines, can support frontline clinicians in applying the most current evaluation and management guidance in the setting of an emerging infectious disease outbreak when those guidelines are evolving over time. Here, we describe the rapid development and implementation of a CDSS tool embedded in the electronic health record to guide frontline clinicians in the diagnostic evaluation of monkeypox infection and triage patients with potential monkeypox infection to individualized infectious disease physician review.

Immunomodulating therapies for COVID-19 may carry risks of reactivating latent infections in foreign-born people. We conducted a rapid review of infection-related complications of immunomodulatory therapies for COVID-19. We convened a committee of specialists to formulate a screening and management strategy for latent infections in our setting.

Article Synopsis
  • Developed a clinical decision support system (CDSS) called CORAL to streamline the evaluation and management of hospitalized patients under investigation for COVID-19, aiming to reduce transmission risks and optimize healthcare resources.
  • Pre- and post-implementation results showed that CORAL decreased the frequency of unnecessary retesting, shortened the time and duration of patient isolation, and significantly reduced the workload for infectious disease (ID) physicians.
  • CORAL proved to be effective in evaluating PUIs, with no positive test results within 7 days after precautions were lifted, highlighting its reliability in safely discontinuing isolation.

Multidrug-resistant (MDR) infections have been identified globally among men who have sex with men (MSM). The highly drug-resistant phenotype often confounds initial antimicrobial therapy, placing patients at risk for adverse outcomes, the development of more drug-resistant strains, and additional treatment failures. New macrolide-resistant strains complicate treatment further as azithromycin is a next-in-line antibiotic for MDR strains, and an antibiotic-strain combination confounded by gaps in validated clinical breakpoints for clinical laboratories to interpret macrolide resistance in We present the first high-resolution genomic analyses of 2,097 U.

Introduction: This study aimed to compare demographics, disease characteristics, and outcomes of patients with HIV-infection with non-small-cell lung cancer (NSCLC) with the general NSCLC population.

Patients And Methods: A retrospective cohort study was used to compare the HIV-infected and -uninfected groups. Medical records of all patients who were HIV-positive diagnosed with NSCLC between 2000 and 2016 at Yale New Haven Hospital (New Haven, CT) were reviewed and compared with the general Yale NSCLC population regarding demographics, NSCLC characteristics, treatment, and survival.

Zygomycosis is an angioinvasive fungal infection with a high mortality rate. Cutaneous zygomycosis is the second most common form of the disease, typically characterized by necrotic eschars in an immunocompromised host. We report an unusual case of superficial intertrigo resistant to conventional therapies caused by in a patient with HIV and diabetes.

Background: Lung cancer is a major cause of death in HIV-infected (HIV+) persons. In this study, we compared the prevalence of tumour EGFR and KRAS mutations in a cohort of lung adenocarcinoma patients by HIV status.

Methods: We collected data from 55 HIV+ patients with lung adenocarcinoma matched to 136 uninfected comparators.
