BACKGROUND: As part of COVID-19 mitigation strategies, emergency nutrition program adaptations were implemented, but evidence of the effects is limited. Compared to the standard protocol, the full adapted protocol included adapted admissions criteria, simplified dosing, and reduced visit frequency; partially adapted protocols consisting of only some of these modifications were also implemented. To enable evidence-based nutrition program modifications as the context evolved, this study was conducted to characterize how protocol adaptations in South Sudan affected Outpatient Therapeutic Feeding Program outcomes. METHODS: A mixed methods approach consisting of secondary analysis of individual-level nutrition program data and key informant interviews was used. Analyses focused on program implementation and severe acute malnutrition treatment outcomes under the standard, full COVID-19 adapted, and partially adapted treatment protocols from 2019 through 2021. Analyses compared characteristics and outcomes by different admission types under the standard protocol and across four different treatment protocols. Regression models evaluated the odds of recovery and mean length of stay (LoS) under the four protocols. RESULTS: Very few (1.6%; n = 156) children admitted based on low weight-for-height alone under the standard protocol would not have been eligible for admission under the adapted protocol. Compared to the full standard protocol, the partially adapted (admission only) and partially adapted (admission and dosing) protocols had lower LoS of 28.4 days (CI - 30.2, - 26.5) and 5.1 days (CI - 6.2, - 4.0); the full adapted protocol had a decrease of 3.0 (CI - 5.1, - 1.0) days. All adapted protocols had significantly increased adjusted odds ratios (AOR) for recovery compared to the full standard protocol: partially adapted (admission only) AOR = 2.56 (CI 2.18-3.01); partially adapted (admission + dosing) AOR = 1.78 (CI 1.45-2.19); and fully adapted protocol AOR = 2.41 (CI 1.69-3.45). CONCLUSIONS: This study provides evidence that few children were excluded when weight-for-height criteria were suspended. LoS was shortest when only MUAC was used for entry/exit but dosing and visit frequency were unchanged. Significantly shorter LoS with simplified dosing and visit frequency vs. under the standard protocol indicate that protocol adaptations may lead to shorter recovery and program enrollment times. Findings also suggest that good recovery is achievable with reduced visit frequency and simplified dosing.

OBJECTIVE: There is a need for a systematic method to implement the World Health Organization's Clinical Progression Scale (WHO-CPS), an ordinal clinical severity score for coronavirus disease 2019 patients, to electronic health record (EHR) data. We discuss our process of developing guiding principles mapping EHR data to WHO-CPS scores across multiple institutions. MATERIALS AND METHODS: Using WHO-CPS as a guideline, we developed the technical blueprint to map EHR data to ordinal clinical severity scores. We applied our approach to data from 2 medical centers. RESULTS: Our method was able to classify clinical severity for 100% of patient days for 2756 patient encounters across 2 institutions. DISCUSSION: Implementing new clinical scales can be challenging; strong understanding of health system data architecture was integral to meet the clinical intentions of the WHO-CPS. CONCLUSION: We describe a detailed blueprint for how to apply the WHO-CPS scale to patient data from the EHR.

Navi Mumbai Municipal Corporation (NMMC), a local government in Mumbai, India, implemented the first public sector TCV campaign in 2018. This study estimated the delivery costs of this TCV campaign using a Microsoft Excel-based tool based on a micro-costing approach from the government (NMMC) perspective. The campaign's financial (direct expenditures) and economic costs (financial costs plus the monetized value of additional donated or existing items) incremental to the existing immunization program were collected. The data collection methods involved consultations with NMMC staff, reviews of financial and programmatic records of NMMC and the World Health Organization (WHO), and interviews with the health staff of sampled urban health posts (UHPs). Three UHPs were purposively sampled, representing the three dominant residence types in the catchment area: high-rise, slum, and mixed (high-rise and slum) areas. The high-rise area UHP had lower vaccination coverage (47%) compared with the mixed area (71%) and slum area UHPs (76%). The financial cost of vaccine and vaccination supplies (syringes, safety boxes) was $1.87 per dose, and the economic cost was $2.96 per dose in 2018 US dollars. Excluding the vaccine and vaccination supplies cost, the financial delivery cost across the 3 UHPs ranged from $0.37 to $0.53 per dose, and the economic delivery cost ranged from $1.37 to $3.98 per dose, with the highest delivery costs per dose in the high-rise areas. Across all 11 UHPs included in the campaign, the weighted average financial delivery cost was $0.38 per dose, and the economic delivery cost was $1.49 per dose. WHO has recommended the programmatic use of TCV in typhoid-endemic countries, and Gavi has included TCV in its vaccine portfolio. This first costing study of large-scale TCV introduction within a public sector immunization program provides empirical evidence for policymakers, stakeholders, and future vaccine campaign planning.

BACKGROUND: Globally, emergency nutrition program adaptations were implemented as part of COVID-19 mitigation strategies, but the implications of the adoption of all protocol changes at scale in the context of deteriorating food security are not yet well characterized. With ongoing conflict, widespread floods, and declining food security, the secondary impacts of COVID-19 on child survival in South Sudan is of great concern. In light of this, the present study aimed to characterize the impact of COVID-19 on nutrition programming in South Sudan. METHODS: A mixed methods approach including a desk review and secondary analysis of facility-level program data was used to analyze trends in program indicators over time and compare two 15-month periods prior to the onset of COVID-19 (January 2019 - March 2020; "pre-COVID period") and after the start of the pandemic (April 2020 - June 2021; "COVID" period) in South Sudan. RESULTS: The median number of reporting Community Management of Acute Malnutrition sites increased from 1167 pre-COVID to 1189 during COVID. Admission trends followed historic seasonal patterns in South Sudan; however, compared to pre-COVID, declines were seen during COVID in total admissions (- 8.2%) and median monthly admissions (- 21.8%) for severe acute malnutrition. For moderate acute malnutrition, total admissions increased slightly during COVID (1.1%) while median monthly admissions declined (- 6.7%). Median monthly recovery rates improved for severe (92.0% pre-COVID to 95.7% during COVID) and moderate acute malnutrition (91.5 to 94.3%) with improvements also seen in all states. At the national level, rates also decreased for default (- 2.4% for severe, - 1.7% for moderate acute malnutrition) and non-recovery (- 0.9% for severe, - 1.1% for moderate acute malnutrition), with mortality rates remaining constant at 0.05-0.15%. CONCLUSIONS: Within the context of the ongoing COVID-19 pandemic in South Sudan, improved recovery, default, and non-responder rates were observed following adoption of changes to nutrition protocols. Policymakers in South Sudan and other resource-constrained settings should consider if simplified nutrition treatment protocols adopted during COVID-19 improved performance and should be maintained in lieu of reverting to standard treatment protocols.

The hepatitis A vaccine is recommended for all children greater than or equal to 1 year of age, however, the duration of vaccine protection is unknown and protection through adulthood is crucial to prevent symptomatic hepatitis later in life. We report on 25 years of follow-up of a cohort of Alaska Native individuals who were vaccinated in early childhood. We assessed the duration of vaccine protection by calculating the geometric mean concentration and proportion of participants with protective levels of IgG antibody to hepatitis A virus (anti-HAV) (≥20 mIU/mL) every 2 to 3 years. We estimated the amount of time until the anti-HAV dropped below protective levels using survival analyses. At 25 years, 43 of the original 144 participants were available, mean anti-HAV levels were 91.5 mIU/mL, and 35 (81.4%) had protective levels of anti-HAV. Using data from all persons and all time points, a survival analysis estimated 78.7% of participants had protective levels of anti-HAV at 25 years. The high level of protective antibodies in this cohort indicate that supplemental doses of hepatitis A vaccine are not needed 25 years after completion of the vaccine series.

Large COVID-19 outbreaks have occurred in high-density workplaces, such as food processing facilities (1). Alaska's seafood processing industry attracts approximately 18,000 out-of-state workers annually (2). Many of the state's seafood processing facilities are located in remote areas with limited health care capacity. On March 23, 2020, the governor of Alaska issued a COVID-19 health mandate (HM10) to address health concerns related to the impending influx of workers amid the COVID-19 pandemic (3). HM10 required employers bringing critical infrastructure (essential) workers into Alaska to submit a Community Workforce Protective Plan.* On May 15, 2020, Appendix 1 was added to the mandate, which outlined specific requirements for seafood processors, to reduce the risk for transmission of SARS-CoV-2, the virus that causes COVID-19, in these high-density workplaces (4). These requirements included measures to prevent introduction of SARS-CoV-2 into the workplace, including testing of incoming workers and a 14-day entry quarantine before workers could enter nonquarantine residences. After 13 COVID-19 outbreaks in Alaska seafood processing facilities and on processing vessels during summer and early fall 2020, State of Alaska personnel and CDC field assignees reviewed the state's seafood processing-associated cases. Requirements were amended in November 2020 to address gaps in COVID-19 prevention. These revised requirements included restricting quarantine groups to ≤10 persons, pretransfer testing, and serial testing (5). Vaccination of this essential workforce is important (6); until high vaccination coverage rates are achieved, other mitigation strategies are needed in this high-risk setting. Updating industry guidance will be important as more information becomes available.

Alaska Native (AN) people experience higher incidence of, and mortality from, gastric cancer compared to other U.S. populations(1, 2). Compared to the general U.S. population, gastric cancer in AN people occurs at a younger age, is diagnosed at later stages, is more evenly distributed between the sexes, and is more frequently signet-ring or diffuse histology(3). It is known that the prevalence of Helicobacter pylori (Hp) infection, a risk factor for gastric cancer, is high in AN people(4); however, high antimicrobial resistance combined with high reinfection rates in Alaska make treatment at the population level complex(5). In addition, health issues in AN people are uniquely challenging due to the extremely remote locations of many residents. A multiagency workgroup hosted a symposium in Anchorage that brought internationally-recognized experts and local leaders together to evaluate issues around gastric cancer in the AN population. The overall goal of this symposium was to identify the best strategies to combat gastric cancer in the AN population through prevention and early diagnosis.

Accurate interpretations and comparisons of linkage results across jurisdictions require valid and reliable matching methods. We compared existing matching methods used by 6 US state and local health departments (Houston, Texas; Louisiana; Michigan; New York City, New York; North Dakota; and Wisconsin) to link human immunodeficiency virus and viral hepatitis surveillance data with a 14-key automated, hierarchical deterministic matching method. Applicable years varied by disease and jurisdiction, ranging from 1979 to 2016. We calculated percentage agreement and Cohen's kappa coefficient to compare the matching methods used within each jurisdiction. We calculated sensitivity, specificity, and positive predictive value of each matching method, compared with a new standard that included manual review of discrepant cases. Agreement between the existing matching method and the deterministic matching method was 99.6% or higher in all jurisdictions; Cohen's kappa values ranged from 0.87 to 0.98. Sensitivity of the deterministic matching method ranged from 97.4% to 100% in the 6 jurisdictions; specificity ranged from 99.7% to 100%; and positive predictive value ranged from 97.4% to 100%. Although no gold standard exists, prior assessments of existing methods and review of discrepant classifications suggest good accuracy and reliability of our deterministic matching method, with the advantage that our method reduces the need for manual review and allows for standard comparisons across jurisdictions when linking human immunodeficiency virus and viral hepatitis data.

Coinfection with human immunodeficiency virus (HIV) and viral hepatitis is associated with high morbidity and mortality in the absence of clinical management, making identification of these cases crucial. We examined characteristics of HIV and viral hepatitis coinfections by using surveillance data from 15 US states and two cities. Each jurisdiction used an automated deterministic matching method to link surveillance data for persons with reported acute and chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infections, to persons reported with HIV infection. Of the 504 398 persons living with diagnosed HIV infection at the end of 2014, 2.0% were coinfected with HBV and 6.7% were coinfected with HCV. Of the 269 884 persons ever reported with HBV, 5.2% were reported with HIV. Of the 1 093 050 persons ever reported with HCV, 4.3% were reported with HIV. A greater proportion of persons coinfected with HIV and HBV were males and blacks/African Americans, compared with those with HIV monoinfection. Persons who inject drugs represented a greater proportion of those coinfected with HIV and HCV, compared with those with HIV monoinfection. Matching HIV and viral hepatitis surveillance data highlights epidemiological characteristics of persons coinfected and can be used to routinely monitor health status and guide state and national public health interventions.

Rett syndrome is a dominant X-linked disorder caused by point mutations (approximately 80%) or by deletions or insertions (approximately 15% to 18%) in the MECP2 gene. It is most common in females but lethal in males, with a distinctly different phenotype. Rett syndrome patients have severe neurological and behavioral problems. Clinical genetic testing laboratories commonly use characterized genomic DNA reference materials to assure the quality of the testing process; however, none are commercially available for MECP2 genetic testing. The Centers for Disease Control and Prevention's Genetic Testing Reference Material Coordination Program, in collaboration with the genetic testing community and the Coriell Cell Repositories, established 27 new cell lines and characterized the MECP2 mutations in these and in 8 previously available cell lines. DNA samples from the 35 cell lines were tested by eight clinical genetic testing laboratories using DNA sequence analysis and methods to assess copy number (multiplex ligation-dependent probe amplification, semiquantitative PCR, or array-based comparative genomic hybridization). The eight common point mutations known to cause approximately 60% of Rett syndrome cases were identified, as were other MECP2 variants, including deletions, duplications, and frame shift and splice-site mutations. Two of the 35 samples were from males with MECP2 duplications. These MECP2 and other characterized genomic DNA samples are publicly available from the NIGMS Repository at the Coriell Cell Repositories.
