RESUMEN

Background: Prior randomized clinical trials have reported benefit of fluvoxamine ≥200 mg/d vs placebo for patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods: This randomized, double-blind, placebo-controlled, fully remote multisite clinical trial evaluated whether fluvoxamine prevents clinical deterioration in higher-risk outpatients with acute coronavirus disease 2019 (COVID-19). Between December 2020 and May 2021, nonhospitalized US and Canadian participants with confirmed symptomatic infection received fluvoxamine (50 mg on day 1, 100 mg twice daily thereafter) or placebo for 15 days. The primary modified intent-to-treat (mITT) population included participants who started the intervention within 7 days of symptom onset with a baseline oxygen saturation ≥92%. The primary outcome was clinical deterioration within 15 days of randomization, defined as having both (1) shortness of breath (severity ≥4 on a 0-10 scale or requiring hospitalization) and (2) oxygen saturation <92% on room air or need for supplemental oxygen. Results: A total of 547 participants were randomized and met mITT criteria (n = 272 fluvoxamine, n = 275 placebo). The Data Safety Monitoring Board recommended stopping early for futility related to lower-than-predicted event rates and declining accrual concurrent with vaccine availability in the United States and Canada. Clinical deterioration occurred in 13 (4.8%) participants in the fluvoxamine group and 15 (5.5%) participants in the placebo group (absolute difference at day 15, 0.68%; 95% CI, -3.0% to 4.4%; log-rank P = .91). Conclusions: This trial did not find fluvoxamine efficacious in preventing clinical deterioration in unvaccinated outpatients with symptomatic COVID-19. It was stopped early and underpowered due to low primary outcome rates. Clinical Trials Registration: ClinicalTrials.gov Identifier: NCT04668950.

RESUMEN

PROBLEM: As part of a curriculum renewal, in 2020, Washington University School of Medicine in St. Louis sought to create an integrated curriculum that allows students to explore 4 academic career pathways (advocacy/global health, education, innovation, and research) and engage in scholarship activities-the Inquiry Curriculum. The curriculum needed to focus on foundational scholarship skills that would be applicable to all pathways. This article describes the process used to develop the curriculum learning objectives and lessons learned from initial implementation. APPROACH: The authors used a modified Delphi process to survey faculty experts from the 4 pathways to determine the objectives (March-May 2020). Twenty-four faculty were surveyed about 48 initial objectives created using Glassick's scholarship criteria. After 2 rounds, 28 objectives met consensus. Further oversight committee review and revisions by session leads resulted in 77 unique objectives for 23 sessions in the curriculum that launched in spring 2021. OUTCOMES: Four themes were identified from student feedback: (1) the Inquiry Curriculum framework creates opportunities for students to gain exposure to various approaches to understanding and addressing health care problems, (2) the curriculum targeted higher-level objectives for traditional research content and lower-level objectives for nontraditional content, (3) Glassick's criteria provided a useful structure for students to understand the rationale for and ordering of content, and (4) the curriculum had natural overlap with content often taught elsewhere in the curriculum, including evidence-based medicine, health equity, public and population health, and quality improvement and patient safety. NEXT STEPS: The authors plan to consolidate sessions where there is redundancy, expand other sessions that require more time, and more purposefully discuss prior content when redundancy is intentional. Exploring other potential measures of curricular success, such as student learning outcomes, scholarly productivity, and impact on future scholarship engagement and career paths, is part of ongoing work.

RESUMEN

BACKGROUND: The symptoms of coronavirus disease 2019 (COVID-19) appear to be heterogenous, and the typical course of these symptoms is unknown. Our objectives were to characterize the common trajectories of COVID-19 symptoms and to assess how symptom course predicts other symptom changes as well as clinical deterioration. METHODS: One hundred sixty-two participants with acute COVID-19 responded to surveys up to 31 times for up to 17 days. Several statistical methods were used to characterize the temporal dynamics of these symptoms. Because 9 participants showed clinical deterioration, we explored whether these participants showed any differences in symptom profiles. RESULTS: Trajectories varied greatly between individuals, with many having persistently severe symptoms or developing new symptoms several days after being diagnosed. A typical trajectory was for a symptom to improve at a decremental rate, with most symptoms still persisting to some degree at the end of the reporting period. The pattern of symptoms over time suggested a fluctuating course for many patients. Participants who showed clinical deterioration were more likely to present with higher reports of severity of cough and diarrhea. CONCLUSIONS: The course of symptoms during the initial weeks of COVID-19 is highly heterogeneous and is neither predictable nor easily characterized using typical survey methods. This has implications for clinical care and early-treatment clinical trials. Additional research is needed to determine whether the decelerating improvement pattern seen in our data is related to the phenomenon of patients reporting long-term symptoms and whether higher symptoms of diarrhea in early illness presages deterioration.

RESUMEN

Importance: Coronavirus disease 2019 (COVID-19) may lead to serious illness as a result of an excessive immune response. Fluvoxamine may prevent clinical deterioration by stimulating the σ-1 receptor, which regulates cytokine production. Objective: To determine whether fluvoxamine, given during mild COVID-19 illness, prevents clinical deterioration and decreases the severity of disease. Design, Setting, and Participants: Double-blind, randomized, fully remote (contactless) clinical trial of fluvoxamine vs placebo. Participants were community-living, nonhospitalized adults with confirmed severe acute respiratory syndrome coronavirus 2 infection, with COVID-19 symptom onset within 7 days and oxygen saturation of 92% or greater. One hundred fifty-two participants were enrolled from the St Louis metropolitan area (Missouri and Illinois) from April 10, 2020, to August 5, 2020. The final date of follow-up was September 19, 2020. Interventions: Participants were randomly assigned to receive 100 mg of fluvoxamine (n = 80) or placebo (n = 72) 3 times daily for 15 days. Main Outcomes and Measures: The primary outcome was clinical deterioration within 15 days of randomization defined by meeting both criteria of (1) shortness of breath or hospitalization for shortness of breath or pneumonia and (2) oxygen saturation less than 92% on room air or need for supplemental oxygen to achieve oxygen saturation of 92% or greater. Results: Of 152 patients who were randomized (mean [SD] age, 46 [13] years; 109 [72%] women), 115 (76%) completed the trial. Clinical deterioration occurred in 0 of 80 patients in the fluvoxamine group and in 6 of 72 patients in the placebo group (absolute difference, 8.7% [95% CI, 1.8%-16.4%] from survival analysis; log-rank P = .009). The fluvoxamine group had 1 serious adverse event and 11 other adverse events, whereas the placebo group had 6 serious adverse events and 12 other adverse events. Conclusions and Relevance: In this preliminary study of adult outpatients with symptomatic COVID-19, patients treated with fluvoxamine, compared with placebo, had a lower likelihood of clinical deterioration over 15 days. However, the study is limited by a small sample size and short follow-up duration, and determination of clinical efficacy would require larger randomized trials with more definitive outcome measures. Trial Registration: ClinicalTrials.gov Identifier: NCT04342663.

RESUMEN

Antimicrobial resistance (AMR) is an urgent public health threat, and continues to be on the rise. Basic microbiological research is the foundation for addressing knowledge gaps both for the development of new antibiotics, diagnostics and preventives but also to inform strategies to mitigate the transmission of resistance and drug resistant microorganisms. Translating this research into new products to reinvigorate dwindling pipelines, especially for new antibiotics, is one of the main challenges faced in addressing AMR. The scientific complexity is compounded by the market uncertainty of any new products leading to a large proportion of pharmaceutical companies exiting the market. Consequently, a number of initiatives were developed to reinvigorate the AMR research and development (R&D) landscape. Despite all these efforts, the antibiotic pipeline remains inadequate to keep up with the increasing rates of resistance globally. Given the number of individual and multilateral actions, there is an urgent need for a common platform and coordination to ensure that resources are adequately used to address the critical challenges posed by AMR globally hence the founding of the Global AMR R&D Hub to take on this role.

RESUMEN

BACKGROUND: An antimicrobial stewardship program (ASP) is one of the core elements needed to optimize antimicrobial use. Although collaboration at the national level to address the importance of ASPs and antimicrobial resistance has occurred in the Asia Pacific region, hospital-level ASP implementation in this region has not been comprehensively evaluated. METHODS: We conducted a systematic review and meta-analysis to assess the efficacy of ASPs in inpatient settings in the Asia Pacific region from January 2005 through March 2016. The impact of ASPs on various outcomes, including patient clinical outcomes, antimicrobial prescription outcomes, microbiological outcomes, and expenditure were assessed. RESULTS: Forty-six studies were included for a systematic review and meta-analysis. The pooled risk ratio for mortality from ASP before-after trials and 2-group comparative studies were 1.03 (95% confidence interval [CI], .88-1.19) and 0.69 (95% CI, .56-.86), respectively. The pooled effect size for change in overall antimicrobial and carbapenem consumption (% difference) was -9.74% (95% CI, -18.93% to -.99%) and -10.56% (95% CI, -19.99% to -3.03%), respectively. Trends toward decreases in the incidence of multidrug-resistant organisms and antimicrobial expenditure (range, 9.7%-58.1% reduction in cost in the intervention period/arm) were also observed. CONCLUSIONS: ASPs in inpatient settings in the Asia Pacific region appear to be safe and effective to reduce antimicrobial consumption and improve outcomes. However, given the significant variations in assessing the efficacy of ASPs, high-quality studies using standardized surveillance methodology for antimicrobial consumption and similar metrics for outcome measurement are needed to further promote antimicrobial stewardship in this region.

RESUMEN

Ramsay Hunt Syndrome (RHS) is a rare complication of latent varicella-zoster virus (VZV) infection that can occur in immunocompetent host. It usually involves ipsilateral facial paralysis, ear pain and facial vesicles. Disseminated herpes zoster is another complication of VZV infection typically seen in immunocompromised hosts. We describe a patient with relapsed chronic lymphocytic leukemia (CLL) who presented simultaneously with RHS and disseminated herpes zoster. While other complications have been documented to coexist with RHS, to our knowledge, this is the first reported case in the literature of concurrent RHS with disseminated herpes zoster.
