Romero-Brufau, Santiago; Chopra, Ayush; Ryu, Alex J; Gel, Esma; Raskar, Ramesh; Kremers, Walter; Anderson, Karen S; Subramanian, Jayakumar; Krishnamurthy, Balaji; Singh, Abhishek; Pasupathy, Kalyan; Dong, Yue; O'Horo, John C; Wilson, Walter R; Mitchell, Oscar; Kingsley, Thomas C
OBJECTIVE:To estimate population health outcomes with delayed second dose versus standard schedule of SARS-CoV-2 mRNA vaccination. DESIGN:Simulation agent based modeling study. SETTING:Simulated population based on real world US county. PARTICIPANTS:The simulation included 100 000 agents, with a representative distribution of demographics and occupations. Networks of contacts were established to simulate potentially infectious interactions though occupation, household, and random interactions. INTERVENTIONS:Simulation of standard covid-19 vaccination versus delayed second dose vaccination prioritizing the first dose. The simulation runs were replicated 10 times. Sensitivity analyses included first dose vaccine efficacy of 50%, 60%, 70%, 80%, and 90% after day 12 post-vaccination; vaccination rate of 0.1%, 0.3%, and 1% of population per day; assuming the vaccine prevents only symptoms but not asymptomatic spread (that is, non-sterilizing vaccine); and an alternative vaccination strategy that implements delayed second dose for people under 65 years of age, but not until all those above this age have been vaccinated. MAIN OUTCOME MEASURES:Cumulative covid-19 mortality, cumulative SARS-CoV-2 infections, and cumulative hospital admissions due to covid-19 over 180 days. RESULTS:236 for 90%, 80%, and 70% first dose efficacy, respectively. The delayed second dose strategy was optimal for vaccine efficacies at or above 80% and vaccination rates at or below 0.3% of the population per day, under both sterilizing and non-sterilizing vaccine assumptions, resulting in absolute cumulative mortality reductions between 26 and 47 per 100 000. The delayed second dose strategy for people under 65 performed consistently well under all vaccination rates tested. CONCLUSIONS:A delayed second dose vaccination strategy, at least for people aged under 65, could result in reduced cumulative mortality under certain conditions.

Shamout, Farah E; Shen, Yiqiu; Wu, Nan; Kaku, Aakash; Park, Jungkyu; Makino, Taro; Jastrzębski, Stanisław; Witowski, Jan; Wang, Duo; Zhang, Ben; Dogra, Siddhant; Cao, Meng; Razavian, Narges; Kudlowitz, David; Azour, Lea; Moore, William; Lui, Yvonne W; Aphinyanaphongs, Yindalon; Fernandez-Granda, Carlos; Geras, Krzysztof J
During the coronavirus disease 2019 (COVID-19) pandemic, rapid and accurate triage of patients at the emergency department is critical to inform decision-making. We propose a data-driven approach for automatic prediction of deterioration risk using a deep neural network that learns from chest X-ray images and a gradient boosting model that learns from routine clinical variables. Our AI prognosis system, trained using data from 3661 patients, achieves an area under the receiver operating characteristic curve (AUC) of 0.786 (95% CI: 0.745-0.830) when predicting deterioration within 96 hours. The deep neural network extracts informative areas of chest X-ray images to assist clinicians in interpreting the predictions and performs comparably to two radiologists in a reader study. In order to verify performance in a real clinical setting, we silently deployed a preliminary version of the deep neural network at New York University Langone Health during the first wave of the pandemic, which produced accurate predictions in real-time. In summary, our findings demonstrate the potential of the proposed system for assisting front-line physicians in the triage of COVID-19 patients.

A Novel Diagnostic Test to Screen SARS-CoV-2 Variants Containing E484K and N501Y Mutations [Letter]
Zhao, Yanan; Lee, Annie; Composto, Kaelea; Cunningham, Marcus H; Mediavilla, Jose R; Fennessey, Samantha; Corvelo, André; Chow, Kar Fai; Zody, Michael; Chen, Liang; Kreiswirth, Barry N; Perlin, David S
Spike protein mutations E484K and N501Y carried by SARS-CoV-2 variants have been associated with concerning changes of the virus, including resistance to neutralizing antibodies and increased transmissibility. While the concerning variants are fast spreading in various geographical areas, identification and monitoring of these variants is lagging far behind, due in large part to the slow speed and insufficient capacity of viral sequencing. In response to the unmet need for a fast and efficient screening tool, we developed a single-tube duplex molecular assay for rapid and simultaneous identification of E484K and N501Y mutations from nasopharyngeal swab (NS) samples within 2.5 h from sample preparation to report. Using this tool, we screened a total of 1135 clinical NS samples collected from COVID patients at 8 hospitals within the Hackensack Meridian Health network in New Jersey between late December 2020 and March 2021. Our data revealed dramatic increases in the frequencies of both E484K and N501Y over time, underscoring the need for continuous epidemiological monitoring.

Using Objective Structured Clinical Exams (OSCE) to Teach Neurology Residents to Disclose Prognosis after Hypoxic Ischemic Brain Injury
Carroll, Elizabeth; Nelson, Aaron; Kurzweil, Arielle; Zabar, Sondra; Lewis, Ariane
BACKGROUND:Neurologists need to be adept at disclosing prognosis and breaking bad news. Objective structured clinical examinations (OSCE) allow trainees to practice these skills. METHODS:In 2017, in conjunction with the NYU School of Medicine Simulation Center, neurology faculty designed an OSCE case in which a resident had to inform a standardized patient (SP) her father had severe global hypoxic ischemic injury. The residents were surveyed on the experience using a Likert scale from 1 (worst) to 5 (best). The SP completed a behavioral anchored checklist and marked items as "not done," "partly done," or "well done". RESULTS:57 third and fourth year neurology residents completed the case from 2018 to 2020, 54 (95%) of whom completed the post-OSCE survey. Residents reported feeling moderately prepared for the simulation (mean Likert score 3.7/5), and thought their performance was average (3.4/5). Overall, they found the case to be very helpful (4.6/5). The residents performed well in the realms of maintaining professionalism (64% rated "well done"), developing a relationship (62% rated "well done"), and information gathering (61% rated "well done"). There was room for improvement in the realms of providing education and presenting the bad news (39% and 37% rated "partly/not done," respectively). CONCLUSIONS:OSCE cases can be used to teach neurology trainees how to discuss prognosis and break bad news. Feedback about this simulation was positive, though its efficacy has yet to be evaluated and could be a future direction of study.

IL-5 mediates monocyte phenotype and pain outcomes in fibromyalgia
Merriwether, Ericka N; Agalave, Nilesh M; Dailey, Dana L; Rakel, Barbara A; Kolker, Sandra J; Lenert, Melissa E; Spagnola, William H; Lu, Ying; Geasland, Katharine M; Allen, Lee-Ann H; Burton, Michael D; Sluka, Kathleen A
Fibromyalgia (FM) is characterized by widespread chronic pain, fatigue, and somatic symptoms. The influence of phenotypic changes in monocytes on symptoms associated with FM are not fully understood. The primary aim of this study was to take a comprehensive whole-body to molecular approach in characterizing relationships between monocyte phenotype and FM symptoms in relevant clinical populations. LPS-evoked and spontaneous secretion of IL-5 and other select cytokines from circulating monocytes was higher in women with FM compared to women without pain. Additionally, greater secretion of IL-5 was significantly associated with pain and other clinically relevant psychological and somatic symptoms of FM. Further, higher levels of pain and pain-related symptoms were associated with a lower percentage of intermediate monocytes (CD14/CD16) and a greater percentage of non-classical monocytes (CD14/CD16) in women with FM. Based on findings from individuals with FM, we examined the role of IL-5, an atypical cytokine secreted from monocytes, in an animal model of widespread muscle pain. Results from the animal model show that IL-5 produces analgesia and polarizes monocytes toward an anti-inflammatory phenotype (CD206). Taken together, our data suggest that monocyte phenotype and their cytokine profiles are associated with pain-related symptoms in individuals with FM. Furthermore, our data show that IL-5 has a potential role in analgesia in an animal model of FM. Thus, targeting anti-inflammatory cytokines such as IL-5 in secreted by circulating leukocytes could serve as a promising intervention to control pain and other somatic symptoms associated with FM.

Does incarceration influence patients' goals for opioid use disorder treatment? A qualitative study of buprenorphine treatment in jail
Vail, William; Faro, Elissa; Watnick, Dana; Giftos, Jonathan; Fox, Aaron D
BACKGROUND:Correctional facilities increasingly offer medications for opioid use disorder (OUD), including buprenorphine. Nevertheless, retention in treatment post-incarceration is suboptimal and overdose mortality remains high. Our objectives were to understand how incarcerated patients viewed buprenorphine treatment and identify modifiable factors that influenced treatment continuation post-release. METHODS:We conducted semi-structured interviews with 22 men receiving buprenorphine treatment in an urban jail. Interviews were audio recorded, professionally transcribed, and analyzed using a grounded-theory approach. Team members constructed preliminary case memos from transcripts, and then interactively discussed themes within respective memos. We established participant 'typologies' by consensus. RESULTS:Distinct typologies emerged based on participants' post-release treatment goals: (1) those who viewed buprenorphine treatment as a cure for OUD; (2) those who thought buprenorphine would help manage opioid-related problems; and (3) those who did not desire OUD treatment. Participants also described common social structural barriers to treatment continuation and community re-integration. Participants reported that post-release housing instability, unemployment, and negative interactions with parole contributed to opioid use relapse and re-incarceration. CONCLUSION:Participants had different goals for post-release buprenorphine treatment continuation, but their prior experiences suggested that social structural issues would complicate these plans. Incarceration can intensify marginalization, which when combined with heightened legal supervision, reinforced cycles of release, relapse, and re-incarceration. Participants valued buprenorphine treatment, but other structural and policy changes will be necessary to reduce incarceration-related inequities in opioid overdose mortality.

Dasotraline in adults with attention deficit hyperactivity disorder: a placebo-controlled, fixed-dose trial
Adler, Lenard A; Goldman, Robert; Hopkins, Seth C; Koblan, Kenneth S; Kent, Justine; Hsu, Jay; Loebel, Antony
In a previous study, dasotraline demonstrated efficacy at a dose of 8 mg/day in adults with attention deficit hyperactivity disorder (ADHD). The aim of the current study was to evaluate the efficacy and safety of dasotraline in doses of 4 and 6 mg/day. Adults meeting Diagnostic and Statistical Manual of Mental Disorders, 5th edition criteria for ADHD were randomized to 8 weeks of double-blind, once-daily, fixed-dose treatment with dasotraline 4 mg/day, 6 mg/day, or placebo. The primary efficacy endpoint was changed in the ADHD Rating Scale, Version IV (ADHD RS-IV) total score. Secondary efficacy endpoints included the Clinical Global Impression, Severity (CGI-S) Scale. Least squares mean reduction at week 8 in the ADHD RS-IV HV total score was not significantly greater (vs. placebo) in the dasotraline 4 mg/day group (-15.0 vs. -13.9; n.s.; or in the dasotraline 6 mg/day group (-16.5 vs. -13.9; P = 0.074; Hochberg correction). Treatment with dasotraline 6 mg/day was significant at week 8 (uncorrected) on the ADHD RS-IV total score (P = 0.037) and the CGI-S score (P = 0.011). Treatment with the 4 mg/day dose of dasotraline was NS. Treatment with dasotraline was generally well tolerated. The results provide additional evidence that supports the potential efficacy of dasotraline, in doses of 6 mg/day, in adults with ADHD.

Adaptation of the Flu-FIT Program for Patient-Aligned Care Teams: A Quality Improvement Project
Funes, Sofia A; Flores, Claudia; Davidow, Amy L; Friedman, Stephen; Korenblit, Pearl; Thomas, Pauline
The Flu-FIT program aims to increase colorectal cancer screening rates by offering a home fecal immunochemical test (FIT) at the time of annual influenza immunization. This program was piloted at a VA campus in New Jersey during the 2018-2019 influenza season, with a 9% increase in colorectal cancer screening rates. In the 2019-2020 season, the program was implemented in 6 primary care teams; 6 additional teams maintaining standard of care served as a comparison group. A total of 816 patients aged 50 to 75 years were eligible for participation; 509 patients were available for analysis, 242 in the Flu-FIT group and 267 in the comparison group. The Flu-FIT group patients were 2.4 times more likely to accept FIT kits (95% confidence interval: 1.6-3.6, P = .001). The colorectal cancer screening rates increased 77.0% to 81.9% in the Flu-FIT group and 77.0% to 79.8% in the comparison group (P > .05).
