Shehab N , Alschuler L , Mc ILvenna S , Gonzaga Z , Laing A , deRoode D , Dantes RB , Betz K , Zheng S , Abner S , Stutler E , Geimer R , Benin AL . J Am Med Inform Assoc 2024 OBJECTIVE: This article presents the National Healthcare Safety Network (NHSN)'s approach to automation for public health surveillance using digital quality measures (dQMs) via an open-source tool (NHSNLink) and piloting of this approach using real-world data in a newly established collaborative program (NHSNCoLab). The approach leverages Health Level Seven Fast Healthcare Interoperability Resources (FHIR) application programming interfaces to improve data collection and reporting for public health and patient safety beginning with common, clinically significant, and preventable patient harms, such as medication-related hypoglycemia, healthcare facility-onset Clostridioides difficile infection, and healthcare-associated venous thromboembolism. CONCLUSIONS: The NHSN's FHIR dQMs hold the promise of minimizing the burden of reporting, improving accuracy, quality, and validity of data collected by NHSN, and increasing speed and efficiency of public health surveillance. |
Fatal occupational asthma in cannabis production - Massachusetts, 2022
Weaver VM , Hua JT , Fitzsimmons KM , Laing JR , Farah W , Hart A , Braegger TJ , Reid M , Weissman DN . MMWR Morb Mortal Wkly Rep 2023 72 (46) 1257-1261 Multiple respiratory hazards have been identified in the cannabis cultivation and production industry, in which occupational asthma and work-related exacerbation of preexisting asthma have been reported. An employee working in a Massachusetts cannabis cultivation and processing facility experienced progressively worsening work-associated respiratory symptoms, which culminated in a fatal asthma attack in January 2022. This report represents findings of an Occupational Safety and Health Administration inspection, which included a worksite exposure assessment, coworker and next-of-kin interviews, medical record reviews, and collaboration with the Massachusetts Department of Public Health. Respiratory tract or skin symptoms were reported by four of 10 coworkers with similar job duties. Prevention is best achieved through a multifaceted approach, including controlling asthmagen exposures, such as cannabis dust, providing worker training, and conducting medical monitoring for occupational allergy. Evaluation of workers with new-onset or worsening asthma is essential, along with prompt diagnosis and medical management, which might include cessation of work and workers' compensation when relation to work exposures is identified. It is important to recognize that work in cannabis production is potentially causative. |
Selective retention of virus-specific tissue-resident T cells in healed skin after recovery from herpes zoster
Laing KJ , Ouwendijk WJD , Campbell VL , McClurkan CL , Mortazavi S , Elder Waters M , Krist MP , Tu R , Nguyen N , Basu K , Miao C , Schmid DS , Johnston C , Verjans Gmgm , Koelle DM . Nat Commun 2022 13 (1) 6957 Herpes zoster is a localized skin infection caused by reactivation of latent varicella-zoster virus. Tissue-resident T cells likely control skin infections. Zoster provides a unique opportunity to determine if focal reinfection of human skin boosts local or disseminated antigen-specific tissue-resident T cells. Here, we show virus-specific T cells are retained over one year in serial samples of rash site and contralateral unaffected skin of individuals recovered from zoster. Consistent with zoster resolution, viral DNA is largely undetectable on skin from day 90 and virus-specific B and T cells decline in blood. In skin, there is selective infiltration and long-term persistence of varicella-zoster virus-specific T cells in the rash site relative to the contralateral site. The skin T cell infiltrates express the canonical tissue-resident T cell markers CD69 and CD103. These findings show that zoster promotes spatially-restricted long-term retention of antigen-specific tissue-resident T cells in previously infected skin. |

Clifton GT , Pati R , Krammer F , Laing ED , Broder CC , Mendu DR , Simons MP , Chen HW , Sugiharto VA , Kang AD , Stadlbauer D , Pratt KP , Bandera BC , Fritz DK , Millar EV , Burgess TH , Chung KK . MMWR Morb Mortal Wkly Rep 2021 70 (9) 308-311 Protecting health care workers from COVID-19 remains a priority during the ongoing pandemic. Accurate assessment of the risk for infection among health care workers is important in determining the effectiveness of infection control plans. In late March 2020, a total of 591 U.S. Army personnel from three units were deployed from areas in which COVID-19 incidence was low to the Javits New York Medical Station (JMS), a 452-bed Federal Emergency Management Agency Federal Medical Station in New York City (NYC), to provide care to COVID-19 patients. Army personnel followed a rigorous infection control plan and remained largely isolated from the surrounding community while in NYC. During April 3–25, a total of 1,095 COVID-19 patients were admitted from NYC area hospitals to the JMS ward or intensive care unit (ICU). A cross-sectional study of the prevalence of SARS-CoV-2 infection among 336 active duty soldiers enrolled in a prevalence study identified an infection rate of 1.7% overall and 0.9% in the 223 (66.4%) enrolled soldiers who provided direct care to COVID-19 patients. A well-designed and well-implemented infection control plan can mitigate the risk for SARS-CoV-2, the virus that causes COVID-19, infection in health care settings, including nontraditional settings. |
Media Reports as a Tool for Timely Monitoring of COVID-19-Related Deaths Among First Responders-United States, April 2020.

Public Health Rep 2021 136 (3) 315-319 We aimed to describe coronavirus disease 2019 (COVID-19) deaths among first responders early in the COVID-19 pandemic. We used media reports to gather timely information about COVID-19-related deaths among first responders during March 30-April 30, 2020, and evaluated the sensitivity of media scanning compared with traditional surveillance. We abstracted information about demographic characteristics, occupation, underlying conditions, and exposure source. Twelve of 19 US public health jurisdictions with data on reported deaths provided verification, and 7 jurisdictions reported whether additional deaths had occurred; we calculated the sensitivity of media scanning among these 7 jurisdictions. We identified 97 COVID-19-related first-responder deaths during the study period through media and jurisdiction reports. Participating jurisdictions reported 5 deaths not reported by the media. Sixty-six decedents worked in law enforcement, and 31 decedents worked in fire/emergency medical services. Media reports rarely noted underlying conditions. The media scan sensitivity was 88% (95% CI, 73%-96%) in the subset of 7 jurisdictions. Media reports demonstrated high sensitivity in documenting COVID-19-related deaths among first responders; however, information on risk factors was scarce. Routine collection of data on industry and occupation could improve understanding of COVID-19 morbidity and mortality among all workers. |
Use of claims data to estimate annual cervical cancer screening percentages in Portland metropolitan area, Oregon.
Abdullah N , Laing RS , Hariri S , Young CM , Schafer S . Cancer Epidemiol 2016 41 106-112 ![]() ![]() BACKGROUND: Human papillomavirus (HPV) vaccine should reduce cervical dysplasia before cervical cancer. However, dysplasia diagnosis is screening-dependent. Accurate screening estimates are needed. PURPOSE: To estimate the percentage of women in a geographic population that has had cervical cancer screening. METHODS: We analyzed claims data for (Papanicolau) Pap tests from 2008-2012 to estimate the percentage of insured women aged 18-39 years screened. We estimated screening in uninsured women by dividing the percentage of insured Behavioral Risk Factor Surveillance Survey respondents reporting previous-year testing by the percentage of uninsured respondents reporting previous-year testing, and multiplying this ratio by claims-based estimates of insured women with previous-year screening. We calculated a simple weighted average of the two estimates to estimate overall screening percentage. We estimated credible intervals using Monte-Carlo simulations. RESULTS: During 2008-2012, an annual average of 29.6% of women aged 18-39 years were screened. Screening increased from 2008 to 2009 in all age groups. During 2009-2012, the screening percentages decreased for all groups, but declined most in women aged 18-20 years, from 21.5% to 5.4%. Within age groups, compared to 2009, credible intervals did not overlap during 2011 (except age group 21-29 years) and 2012, and credible intervals in the 18-20 year group did not overlap with older groups in any year. CONCLUSIONS: This introduces a novel method to estimate population-level cervical cancer screening. Overall, percentage of women screened in Portland, Oregon fell following changes in screening recommendations released in 2009 and later modified in 2012. |
Zoster vaccination increases the breadth of CD4+ T cells responsive to varicella zoster virus
Laing KJ , Russell RM , Dong L , Schmid DS , Stern M , Magaret A , Haas JG , Johnston C , Wald A , Koelle DM . J Infect Dis 2015 212 (7) 1022-31 BACKGROUND: The live, attenuated varicella vaccine strain (vOka) is the only licensed therapeutic vaccine. Boost of VZV-specific cellular immunity is a likely mechanism of action. We examined memory CD4+ T-cell responses to each VZV protein at baseline and after zoster vaccination. METHODS: Serial blood samples were collected from 12 subjects vaccinated with Zostavax and immunogenicity confirmed by direct ex vivo VZV-specific T-cell and antibody assays. CD4+ T-cell lines enriched for VZV-specificity were generated and probed for proliferative responses to every VZV protein and selected peptide sets. RESULTS: Zoster vaccination increased the median magnitude (2.3-fold one month after vaccination) and breadth (4.2-fold one month after vaccination) of VZV-specific CD4+ T-cells. Both measures declined by 6 months. The most prevalent responses at baseline included (highest first) VZV ORFs 68, 4, 37, and 63. After vaccination, responses to ORFs 40, 67, 9, 59, 12, 62, and 18 were also prevalent. The immunogenicity of ORF9 and ORF18 were confirmed using peptides, defining a large number of discrete viral CD4 T-cell epitopes. CONCLUSIONS: The breadth and magnitude of the VZV-specific CD4+ T-cell response increases after zoster vaccination. In addition to glycoprotein E (ORF68), we identified antigenic ORFs that may be useful components of subunit vaccines. |
