Building capacity of community health centers to improve the provision of postpartum care services through data-driven health information technology and innovation
Romero L , Du Mond J , Carneiro PB , Uy R , Osika J , Wallander Gemkow J , Yang TY , Whitt M , Overholser A , Karasu S , Curtis K , Skapik J . J Womens Health (Larchmt) 2024 Maternal morbidity and mortality remain significant challenges in the United States, with substantial burden during the postpartum period. The Centers for Disease Control and Prevention, in partnership with the National Association of Community Health Centers, began an initiative to build capacity in Federally Qualified Health Centers to (1) improve the infrastructure for perinatal care measures and (2) use perinatal care measures to identify and address gaps in postpartum care. Two partner health center-controlled networks implemented strategies to integrate evidence-based recommendations into the clinic workflow and used data-driven health information technology (HIT) systems to improve data standardization for quality improvement of postpartum care services. Ten measures were created to capture recommended care and services. To support measure capture, a data cleaning algorithm was created to prioritize defining pregnancy episodes and delivery dates and address data inconsistencies. Quality improvement activities targeted postpartum care delivery tailored to patients and care teams. Data limitations, including inconsistencies in electronic health record documentation and data extraction practices, underscored the complexity of integrating HIT solutions into postpartum care workflows. Despite challenges, the project demonstrated continuous quality improvement to support data quality for perinatal care measures. Future solutions emphasize the need for standardized data elements, collaborative care team engagement, and iterative HIT implementation strategies to enhance perinatal care quality. Our findings highlight the potential of HIT-driven interventions to improve postpartum care within health centers, with a focus on the importance of addressing data interoperability and documentation challenges to optimize and monitor initiatives to improve postpartum health outcomes. |

PLoS Comput Biol 2024 20 (5) e1011200 During the COVID-19 pandemic, forecasting COVID-19 trends to support planning and response was a priority for scientists and decision makers alike. In the United States, COVID-19 forecasting was coordinated by a large group of universities, companies, and government entities led by the Centers for Disease Control and Prevention and the US COVID-19 Forecast Hub (https://covid19forecasthub.org). We evaluated approximately 9.7 million forecasts of weekly state-level COVID-19 cases for predictions 1-4 weeks into the future submitted by 24 teams from August 2020 to December 2021. We assessed coverage of central prediction intervals and weighted interval scores (WIS), adjusting for missing forecasts relative to a baseline forecast, and used a Gaussian generalized estimating equation (GEE) model to evaluate differences in skill across epidemic phases that were defined by the effective reproduction number. Overall, we found high variation in skill across individual models, with ensemble-based forecasts outperforming other approaches. Forecast skill relative to the baseline was generally higher for larger jurisdictions (e.g., states compared to counties). Over time, forecasts generally performed worst in periods of rapid changes in reported cases (either in increasing or decreasing epidemic phases) with 95% prediction interval coverage dropping below 50% during the growth phases of the winter 2020, Delta, and Omicron waves. Ideally, case forecasts could serve as a leading indicator of changes in transmission dynamics. However, while most COVID-19 case forecasts outperformed a naïve baseline model, even the most accurate case forecasts were unreliable in key phases. Further research could improve forecasts of leading indicators, like COVID-19 cases, by leveraging additional real-time data, addressing performance across phases, improving the characterization of forecast confidence, and ensuring that forecasts were coherent across spatial scales. In the meantime, it is critical for forecast users to appreciate current limitations and use a broad set of indicators to inform pandemic-related decision making. |
A cluster-based law enforcement body armor sizing system: Concept, procedure, and design practice
Hsiao H , Kau TY , Bradtmiller B . Appl Ergon 2024 117 104201 Given the evolution of human body dimensions, the increasing diversity within the law enforcement workforce, the growing risks of assault faced by law enforcement officers (LEOs), and the absence of a national standard for body armor sizing, there is a critical need to explore LEO body size classification. This exploration will facilitate the development of an armor sizing structure that adequately accommodates the current LEO population. This study aimed to address this need by developing a LEO body armor sizing scheme and creating a sizing chart/app. Additionally, a plan was devised for a series of 'sizing vests' that would enhance LEO armor accommodation and facilitate fit assessment. Torso anthropometric data pertaining to body armor sizing were collected from 756 male and 218 female LEOs across different regions of the United States. Based on the collected data, a nine-size system for male LEOs and an eight-size scheme for female LEOs were suggested. Furthermore, a sizing chart/app was proposed to enable LEOs to swiftly identify an armor size that is most likely to fit an individual, considering a few anthropometric characteristics known to LEOs. To supplement the sizing chart/app, a series of 'sizing vests' were recommended. These vests would provide LEOs with a physical means to assess and determine the best-fitting armor size, offering an alternative to relying solely on the sizing chart/app. We recommend that armor manufacturers adopt these new sizing systems and create prototypes of armor that can be evaluated within this sizing structure. This evaluation process will facilitate improved fit and enhanced protection for LEOs. |

N Engl J Med 2023 389 (25) 2355-2362 ![]() Melioidosis, caused by Burkholderia pseudomallei, is a rare but potentially fatal bacterial disease endemic to tropical and subtropical regions worldwide. It is typically acquired through contact with contaminated soil or fresh water. Before this investigation, B. pseudomallei was not known to have been isolated from the environment in the continental United States. Here, we report on three patients living in the same Mississippi Gulf Coast county who presented with melioidosis within a 3-year period. They were infected by the same Western Hemisphere B. pseudomallei strain that was discovered in three environmental samples collected from the property of one of the patients. These findings indicate local acquisition of melioidosis from the environment in the Mississippi Gulf Coast region. |
Design and Implementation of a Federal Program to Engage Community Partners to Reduce Disparities in Adult COVID-19 Immunization Uptake, United States, 2021-2022
Ashenafi SG , Martinez GM , Jatlaoui TC , Koppaka R , Byrne-Zaaloff M , Falcón AP , Frank A , Keitt SH , Matus K , Moss S , Ruddock C , Sun T , Waterman MB , Wu TY . Public Health Rep 2023 333549231208642 Vaccination disparities are part of a larger system of health inequities among racial and ethnic groups in the United States. To increase vaccine equity of racial and ethnic populations, the Centers for Disease Control and Prevention (CDC) designed the Partnering for Vaccine Equity program in January 2021, which funded and supported national, state, local, and community organizations in 50 states-which include Indian Health Service Tribal Areas; Washington, DC; and Puerto Rico-to implement culturally tailored activities to improve access to, availability of, and confidence in COVID-19 and influenza vaccines. To increase vaccine uptake at the local level, CDC partnered with national organizations such as the National Urban League and Asian & Pacific Islander American Health Forum to engage community-based organizations to take action. Lessons learned from the program include the importance of directly supporting and engaging with the community, providing tailored messages and access to vaccines to reach communities where they are, training messengers who are trusted by those in the community, and providing support to funded partners through trainings on program design and implementation that can be institutionalized and sustained beyond the COVID-19 pandemic. Building on these lessons will ensure CDC and other public health partners can continue to advance vaccine equity, increase vaccine uptake, improve health outcomes, and build trust with communities as part of a comprehensive adult immunization infrastructure. |

Forecasting models provide specific, quantitative, and evaluable predictions that inform short-term decisions such as healthcare staffing needs, school closures, and allocation of medical supplies. In 2020, the COVID-19 Forecast Hub (https://covid19forecasthub.org/) collected, disseminated, and synthesized hundreds of thousands of specific predictions from more than 50 different academic, industry, and independent research groups. This manuscript systematically evaluates 23 models that regularly submitted forecasts of reported weekly incident COVID-19 mortality counts in the US at the state and national level. One of these models was a multi-model ensemble that combined all available forecasts each week. The performance of individual models showed high variability across time, geospatial units, and forecast horizons. Half of the models evaluated showed better accuracy than a naïve baseline model. In combining the forecasts from all teams, the ensemble showed the best overall probabilistic accuracy of any model. Forecast accuracy degraded as models made predictions farther into the future, with probabilistic accuracy at a 20-week horizon more than 5 times worse than when predicting at a 1-week horizon. This project underscores the role that collaboration and active coordination between governmental public health agencies, academic modeling teams, and industry partners can play in developing modern modeling capabilities to support local, state, and federal response to outbreaks.Competing Interest StatementAV, MC, and APP report grants from Metabiota Inc outside the submitted work.Funding StatementFor teams that reported receiving funding for their work, we report the sources and disclosures below.

Rollins CK , Calderon J , Wypij D , Taylor AM , Davalji Kanjiker TS , Rohde JS , Maiman M , Zambrano LD , Newhams MM , Rodriguez S , Hart N , Worhach J , Kucukak S , Poussaint TY , Son MBF , Friedman ML , Gertz SJ , Hobbs CV , Kong M , Maddux AB , McGuire JL , Licht PA , Staat MA , Yonker LM , Mazumdar M , Randolph AG , Campbell AP , Newburger JW . JAMA Netw Open 2023 6 (7) e2324369 IMPORTANCE: Acute neurological involvement occurs in some patients with multisystem inflammatory syndrome in children (MIS-C), but few data report neurological and psychological sequelae, and no investigations include direct assessments of cognitive function 6 to 12 months after discharge. OBJECTIVE: To characterize neurological, psychological, and quality of life sequelae after MIS-C. DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional cohort study was conducted in the US and Canada. Participants included children with MIS-C diagnosed from November 2020 through November 2021, 6 to 12 months after hospital discharge, and their sibling or community controls, when available. Data analysis was performed from August 2022 to May 2023. EXPOSURE: Diagnosis of MIS-C. MAIN OUTCOMES AND MEASURES: A central study site remotely administered a onetime neurological examination and in-depth neuropsychological assessment including measures of cognition, behavior, quality of life, and daily function. Generalized estimating equations, accounting for matching, assessed for group differences. RESULTS: Sixty-four patients with MIS-C (mean [SD] age, 11.5 [3.9] years; 20 girls [31%]) and 44 control participants (mean [SD] age, 12.6 [3.7] years; 20 girls [45%]) were enrolled. The MIS-C group exhibited abnormalities on neurological examination more frequently than controls (15 of 61 children [25%] vs 3 of 43 children [7%]; odds ratio, 4.7; 95% CI, 1.3-16.7). Although the 2 groups performed similarly on most cognitive measures, the MIS-C group scored lower on the National Institutes of Health Cognition Toolbox List Sort Working Memory Test, a measure of executive functioning (mean [SD] scores, 96.1 [14.3] vs 103.1 [10.5]). Parents reported worse psychological outcomes in cases compared with controls, particularly higher scores for depression symptoms (mean [SD] scores, 52.6 [13.1] vs 47.8 [9.4]) and somatization (mean [SD] scores, 55.5 [15.5] vs 47.0 [7.6]). Self-reported (mean [SD] scores, 79.6 [13.1] vs 85.5 [12.3]) and parent-reported (mean [SD] scores, 80.3 [15.5] vs 88.6 [13.0]) quality of life scores were also lower in cases than controls. CONCLUSIONS AND RELEVANCE: In this cohort study, compared with contemporaneous sibling or community controls, patients with MIS-C had more abnormal neurologic examinations, worse working memory scores, more somatization and depression symptoms, and lower quality of life 6 to 12 months after hospital discharge. Although these findings need to be confirmed in larger studies, enhanced monitoring may be warranted for early identification and treatment of neurological and psychological symptoms. |
Genetic characterization of two G8P[8] rotavirus strains isolated in Guangzhou, China, in 2020/21: evidence of genome reassortment.
Wang SJ , Chen LN , Wang SM , Zhou HL , Qiu C , Jiang B , Qiu TY , Chen SL , von Seidlein L , Wang XY . BMC Infect Dis 2022 22 (1) 579 ![]() BACKGROUND: The G8 rotavirus genotype has been detected frequently in children in many countries and even became the predominant strain in sub-Saharan African countries, while there are currently no reports from China. In this study we described the genetic characteristics and evolutionary relationship between rotavirus strains from Guangzhou in China and the epidemic rotavirus strains derived from GenBank, 2020-2021. METHODS: Virus isolation and subsequent next-generation sequencing were performed for confirmed G8P[8] specimens. The genetic characteristics and evolutionary relationship were analyzed in comparison with epidemic rotavirus sequences obtained from GenBank. RESULTS: The two Guangzhou G8 strains were DS-1-like with the closest genetic distance to strains circulating in Southeast Asia. The VP7 genes of the two strains were derived from a human, not an animal G8 rotavirus. Large genetic distances in several genes suggested that the Guangzhou strains may not have been transmitted directly from Southeast Asian countries, but have emerged following reassortment events. CONCLUSIONS: We report the whole genome sequence information of G8P[8] rotaviruses recently detected in China; their clinical and epidemiological significance remains to be explored further. |
Design and optimization of a monkeypox virus specific serological assay
Taha TY , Townsend MB , Pohl J , Karem KL , Damon IK , Mbala Kingebeni P , Muyembe Tamfum JJ , Martin JW , Pittman PR , Huggins JW , Satheshkumar PS , Bagarozzi DA Jr , Reynolds MG , Hughes LJ . Pathogens 2023 12 (3) Monkeypox virus (MPXV), a member of the Orthopoxvirus (OPXV) genus, is a zoonotic virus, endemic to central and western Africa that can cause smallpox-like symptoms in humans with fatal outcomes in up to 15% of patients. The incidence of MPXV infections in the Democratic Republic of the Congo, where the majority of cases have occurred historically, has been estimated to have increased as much as 20-fold since the end of smallpox vaccination in 1980. Considering the risk global travel carries for future disease outbreaks, accurate epidemiological surveillance of MPXV is warranted as demonstrated by the recent Mpox outbreak, where the majority of cases were occurring in non-endemic areas. Serological differentiation between childhood vaccination and recent infection with MPXV or other OPXVs is difficult due to the high level of conservation within OPXV proteins. Here, a peptide-based serological assay was developed to specifically detect exposure to MPXV. A comparative analysis of immunogenic proteins across human OPXVs identified a large subset of proteins that could potentially be specifically recognized in response to a MPXV infection. Peptides were chosen based upon MPXV sequence specificity and predicted immunogenicity. Peptides individually and combined were screened in an ELISA against serum from well-characterized Mpox outbreaks, vaccinee sera, and smallpox sera collected prior to eradication. One peptide combination was successful with ~86% sensitivity and ~90% specificity. The performance of the assay was assessed against the OPXV IgG ELISA in the context of a serosurvey by retrospectively screening a set of serum specimens from the region in Ghana believed to have harbored the MPXV-infected rodents involved in the 2003 United States outbreak. |

Crit Care Explor 2023 5 (1) e0827 ![]() Vascular dysfunction and capillary leak are common in critically ill COVID-19 patients, but identification of endothelial pathways involved in COVID-19 pathogenesis has been limited. Angiopoietin-like 4 (ANGPTL4) is a protein secreted in response to hypoxic and nutrient-poor conditions that has a variety of biological effects including vascular injury and capillary leak. OBJECTIVES: To assess the role of ANGPTL4 in COVID-19-related outcomes. DESIGN SETTING AND PARTICIPANTS: Two hundred twenty-five COVID-19 ICU patients were enrolled from April 2020 to May 2021 in a prospective, multicenter cohort study from three different medical centers, University of Washington, University of Southern California and New York University. MAIN OUTCOMES AND MEASURES: Plasma ANGPTL4 was measured on days 1, 7, and 14 after ICU admission. We used previously published tissue proteomic data and lung single nucleus RNA (snRNA) sequencing data from specimens collected from COVID-19 patients to determine the tissues and cells that produce ANGPTL4. RESULTS: Higher plasma ANGPTL4 concentrations were significantly associated with worse hospital mortality (adjusted odds ratio per log(2) increase, 1.53; 95% CI, 1.17-2.00; p = 0.002). Higher ANGPTL4 concentrations were also associated with higher proportions of venous thromboembolism and acute respiratory distress syndrome. Longitudinal ANGPTL4 concentrations were significantly different during the first 2 weeks of hospitalization in patients who subsequently died compared with survivors (p for interaction = 8.1 × 10(-5)). Proteomics analysis demonstrated abundance of ANGPTL4 in lung tissue compared with other organs in COVID-19. ANGPTL4 single-nuclear RNA gene expression was significantly increased in pulmonary alveolar type 2 epithelial cells and fibroblasts in COVID-19 lung tissue compared with controls. CONCLUSIONS AND RELEVANCE: ANGPTL4 is expressed in pulmonary epithelial cells and fibroblasts and is associated with clinical prognosis in critically ill COVID-19 patients. |
Notes from the field: Burkholderia pseudomallei detected in a raccoon carcass linked to a multistate aromatherapy-associated melioidosis outbreak - Texas, 2022
Petras JK , Elrod MG , Ty M , Adams P , Zahner D , Adams A , Calfee MW , Tomlinson C , Serre S , Ryan S , Jakabhazy E , Gee JE , Weiner Z , Bower WA , Negron ME , Hoffmaster AR , Honza H . MMWR Morb Mortal Wkly Rep 2022 71 (50) 1597-1598 Burkholderia pseudomallei, the causative agent of melioidosis, is an environmental gram-negative bacterium endemic in tropical and subtropical regions worldwide. B. pseudomallei can infect humans and a wide range of animals through percutaneous inoculation, inhalation, or ingestion (1). Melioidosis symptoms are nonspecific and vary widely because B. pseudomallei can infect any organ of the body, including the brain. In October 2021, the source of a multistate outbreak of melioidosis that involved four human cases in Georgia, Kansas, Minnesota, and Texas was identified as an aromatherapy room spray imported from India* (2). | | After the discovery of the aromatherapy spray as the outbreak source, the Texas Department of State Health Services (DSHS) learned that a previously healthy pet raccoon, owned by the family of the Texas patient, had broken a bottle of the implicated aromatherapy spray and walked through the liquid. On April 3, 2021, approximately 2 weeks after this exposure, the raccoon displayed acute neurologic symptoms consistent with neurologic melioidosis† and died from an undetermined cause 3 days later. The carcass was wrapped in a cloth robe and buried on the family’s property. The strain found in the aromatherapy bottle (ATS2021) and linked to the outbreak contained a genetic variant, the bimABm allele, which is a virulence factor associated with neurologic melioidosis (3). |
Body models of law enforcement officers for cruiser cab accommodation simulation
Hsiao H , Kau TY , Whisler R , Zwiener J . Hum Factors 2022 187208221140220 OBJECTIVES: This study developed multivariate law enforcement officer (LEO) body models for digital simulation of LEO accommodation in police cruiser cabs. BACKGROUND: Anthropometrically accurate digital LEO body models, representing the United States LEOs, for computerized LEO cruiser interface simulations are lacking. METHODS: Twenty body dimensions (with and without gear combined) of 756 male and 218 female LEOs were collected through a stratified national survey using a data collection trailer that traveled across the US. A multivariate Principal Component Analysis (PCA) approach was used to develop digital LEO body models. RESULTS: Fifteen men and 15 women representing unique body size and shape composition of the LEO population were identified. A combined set of 24 male and female models (removal of 6 redundant models for which female and male models overlapped) is suggested. CONCLUSIONS: A set of 24 digital LEO body models in 3-dimensional form, along with their anthropometric measurements, were developed to facilitate LEO cruiser cab design. APPLICATION: Digital modeling software developers can use the models and their anthropometric data to build digital avatars for simulated evaluation of LEO cruiser cab configuration, console communication-equipment fitting, and cruiser ingress/egress access arrangement. LEO vehicle and equipment designers also can use eight key body dimensions (i.e., stature, buttock-popliteal length, eye height sitting, knee height sitting, shoulder-grip length, popliteal height, sitting height, and body weight) of the body models to recruit 24 human subjects to physically evaluate their vehicle prototypes for improved vehicle and equipment design. |

JAMA Neurol 2022 80 (1) 91-98 IMPORTANCE: In 2020 during the COVID-19 pandemic, neurologic involvement was common in children and adolescents hospitalized in the United States for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-related complications. OBJECTIVE: To provide an update on the spectrum of SARS-CoV-2-related neurologic involvement among children and adolescents in 2021. DESIGN, SETTING, AND PARTICIPANTS: Case series investigation of patients reported to public health surveillance hospitalized with SARS-CoV-2-related illness between December 15, 2020, and December 31, 2021, in 55 US hospitals in 31 states with follow-up at hospital discharge. A total of 2253 patients were enrolled during the investigation period. Patients suspected of having multisystem inflammatory syndrome in children (MIS-C) who did not meet criteria (n=85) were excluded. Patients (<21 years) with positive SARS-CoV-2 test results (reverse transcriptase-polymerase chain reaction and/or antibody) meeting criteria for MIS-C or acute COVID-19 were included in the analysis. EXPOSURE: SARS-CoV-2 infection. MAIN OUTCOMES AND MEASURES: Patients with neurologic involvement had acute neurologic signs, symptoms, or diseases on presentation or during hospitalization. Life-threatening neurologic involvement was adjudicated by experts based on clinical and/or neuroradiological features. Type and severity of neurologic involvement, laboratory and imaging data, vaccination status, and hospital discharge outcomes (death or survival with new neurologic deficits). RESULTS: Of 2168 patients included (58% male; median age, 10.3 years), 1435 (66%) met criteria for MIS-C, and 476 (22%) had documented neurologic involvement. Patients with neurologic involvement vs without were older (median age, 12 vs 10 years) and more frequently had underlying neurologic disorders (107 of 476 [22%] vs 240 of 1692 [14%]). Among those with neurologic involvement, 42 (9%) developed acute SARS-CoV-2-related life-threatening conditions, including central nervous system infection/demyelination (n=23; 15 with possible/confirmed encephalitis, 6 meningitis, 1 transverse myelitis, 1 nonhemorrhagic leukoencephalopathy), stroke (n=11), severe encephalopathy (n=5), acute fulminant cerebral edema (n=2), and Guillain-Barr syndrome (n=1). Ten of 42 (24%) survived with new neurologic deficits at discharge and 8 (19%) died. Among patients with life-threatening neurologic conditions, 15 of 16 vaccine-eligible patients (94%) were unvaccinated. CONCLUSIONS AND RELEVANCE: SARS-CoV-2-related neurologic involvement persisted in US children and adolescents hospitalized for COVID-19 or MIS-C in 2021 and was again mostly transient. Central nervous system infection/demyelination accounted for a higher proportion of life-threatening conditions, and most vaccine-eligible patients were unvaccinated. COVID-19 vaccination may prevent some SARS-CoV-2-related neurologic complications and merits further study. |

Proc Natl Acad Sci U S A 2022 119 (15) e2113561119 ![]() SignificanceThis paper compares the probabilistic accuracy of short-term forecasts of reported deaths due to COVID-19 during the first year and a half of the pandemic in the United States. Results show high variation in accuracy between and within stand-alone models and more consistent accuracy from an ensemble model that combined forecasts from all eligible models. This demonstrates that an ensemble model provided a reliable and comparatively accurate means of forecasting deaths during the COVID-19 pandemic that exceeded the performance of all of the models that contributed to it. This work strengthens the evidence base for synthesizing multiple models to support public-health action. |

Lancet Microbe 2022 3 (4) e265-e273 Background: Molecular diagnostics are considered the most promising route to achievement of rapid, universal drug susceptibility testing for Mycobacterium tuberculosis complex (MTBC). We aimed to generate a WHO-endorsed catalogue of mutations to serve as a global standard for interpreting molecular information for drug resistance prediction. Methods: In this systematic analysis, we used a candidate gene approach to identify mutations associated with resistance or consistent with susceptibility for 13 WHO-endorsed antituberculosis drugs. We collected existing worldwide MTBC whole-genome sequencing data and phenotypic data from academic groups and consortia, reference laboratories, public health organisations, and published literature. We categorised phenotypes as follows: methods and critical concentrations currently endorsed by WHO (category 1); critical concentrations previously endorsed by WHO for those methods (category 2); methods or critical concentrations not currently endorsed by WHO (category 3). For each mutation, we used a contingency table of binary phenotypes and presence or absence of the mutation to compute positive predictive value, and we used Fisher's exact tests to generate odds ratios and Benjamini-Hochberg corrected p values. Mutations were graded as associated with resistance if present in at least five isolates, if the odds ratio was more than 1 with a statistically significant corrected p value, and if the lower bound of the 95% CI on the positive predictive value for phenotypic resistance was greater than 25%. A series of expert rules were applied for final confidence grading of each mutation. Findings: We analysed 41 137 MTBC isolates with phenotypic and whole-genome sequencing data from 45 countries. 38 215 MTBC isolates passed quality control steps and were included in the final analysis. 15 667 associations were computed for 13 211 unique mutations linked to one or more drugs. 1149 (73%) of 15 667 mutations were classified as associated with phenotypic resistance and 107 (07%) were deemed consistent with susceptibility. For rifampicin, isoniazid, ethambutol, fluoroquinolones, and streptomycin, the mutations' pooled sensitivity was more than 80%. Specificity was over 95% for all drugs except ethionamide (914%), moxifloxacin (916%) and ethambutol (933%). Only two resistance mutations were identified for bedaquiline, delamanid, clofazimine, and linezolid as prevalence of phenotypic resistance was low for these drugs. Interpretation: We present the first WHO-endorsed catalogue of molecular targets for MTBC drug susceptibility testing, which is intended to provide a global standard for resistance interpretation. The existence of this catalogue should encourage the implementation of molecular diagnostics by national tuberculosis programmes.

Prevalence and diversity of rotavirus A in pigs: Evidence for a possible reservoir in human infection.
Wu FT , Liu LT , Jiang B , Kuo TY , Wu CY , Liao MH . Infect Genet Evol 2022 98 105198 ![]() BACKGROUND: Rotavirus A (RVA) are a group of diverse viruses causing acute gastroenteritis (AGE) in humans and animals. Zoonotic transmission is an important mechanism for rotavirus evolution and strain diversity in humans, but the extent of pigs as a major reservoir for human infection is not clear. METHODS AND FINDINGS: We have surveyed 153 pig farms across Taiwan with a total of 4588 porcine stool samples from three age groups from 2014 to 2017. Nursing piglets (less than one month of age) had higher detection rate for rotavirus than older age groups. Five VP7 (G) genotypes and 5 VP4 (P) genotypes were found in a total of 14 different G/P genotype combinations. In addition, porcine RVA strains had 2 NSP4 (E) genotypes and 3 VP6 (I) genotypes. A P[3]-like genotype was also discovered among strains collected in 2016 and 2017. CONCLUSIONS: Most of the genes from Taiwanese porcine strains clustered with each other and the lineages formed by these strains were distinct from the sequences of numerous regional variants or globally circulating porcine strains, suggesting an independent evolutionary history for Taiwanese rotavirus genotypes. The close relationship among porcine RVA strains and some unique porcine-like genotypes detected sporadically among human children in swine farms illustrates that pigs might serve as a reservoir for potential zoonotic transmission and novel genotype evolution in Taiwan's insular environment. |
Evaluation of the fall protection of Type I industrial helmets
Wu JZ , Pan CS , Cobb C , Moorehead A , Kau TY , Wimer BM . Ann Biomed Eng 2022 50 (11) 1565-1578 The performance of Type I industrial helmets for fall protection is not required to be tested in standardized tests. The current study analyzed the fall protection performance of Type I industrial helmets and evaluated if the use of a chin strap and the suspension system tightness have any effect on protection performance. Head impact tests were performed using an instrumented manikin. There were 12 combinations of test conditions: with or without chin strap usage, three levels of suspension system tightness, and two impact surfaces. Four representative helmet models (two basic and two advanced models) were selected for the study. Impact tests without a helmet under all other applicable test conditions were used as a control group. There were four replicates for each test condition-a total of 192 impact tests with helmets and eight impact tests for the control group. The peak acceleration and the calculated head impact criteria (HIC) were used to evaluate shock absorption performance of the helmets. The results showed that all four helmet models demonstrated excellent performance for fall protection compared to the barehead control group. The fall protection performance of the advanced helmet models was substantially better than the basic helmet models. However, the effects of the use of chin straps and suspension system tightness on the helmets' fall protection performance were statistically not significant. |
Characterization of Reference Materials for CYP2C9, CYP2C19, VKORC1, CYP2C Cluster Variant, GGCX, and Other Pharmacogenetic Alleles with an Association for Molecular Pathology (AMP) Pharmacogenetics Working Group Tier 2 Status - A GeT-RM Collaborative Project.
Pratt VM , Turner A , Broeckel U , Dawson DB , Gaedigk A , Lynnes TC , Medeiros EB , Moyer AM , Requesens D , Ventrini F , Kalman LV . J Mol Diagn 2021 23 (8) 952-958 ![]() Pharmacogenetic (PGx) testing is increasingly available from clinical and research laboratories. However, only a limited number of quality control and other reference materials (RMs) are currently available for many of the variants that are tested. The Association for Molecular Pathology PGx Work Group has published a series of papers recommending alleles for inclusion in clinical testing. Several of the alleles were not considered for Tier 1 due to a lack of reference materials. To address this need, the Division of Laboratory Systems, Centers for Disease Control and Prevention (CDC) based Genetic Testing Reference Material Coordination Program (GeT-RM), in collaboration with members of the pharmacogenetic testing and research communities and the Coriell Institute for Medical Research, has characterized 18 DNA samples derived from Coriell cell lines. DNA samples were distributed to five volunteer testing laboratories for genotyping using three commercially available and laboratory developed tests. Several Tier 2 variants including CYP2C9*13, CYP2C19*35, the CYP2C cluster variant (rs12777823), two variants in VKORC1 (rs61742245 and rs72547529) related to warfarin resistance and two variants in GGCX (rs12714145 and rs11676382) related to clotting factor activation were identified among these samples. These publicly available materials complement the pharmacogenetic reference materials previously characterized by GeT-RM and will support the quality assurance and quality control programs of clinical laboratories performing pharmacogenetic testing. |
Hand hygiene during the COVID-19 pandemic among people experiencing homelessness-Atlanta, Georgia, 2020.
Montgomery MP , Carry MG , Garcia-Williams AG , Marshall B , Besrat B , Bejarano F , Carlson J , Rutledge T , Mosites E . J Community Psychol 2021 49 (7) 2441-2453 People experiencing homelessness are at risk for coronavirus disease 2019 (COVID-19) and may experience barriers to hand hygiene, a primary recommendation for COVID-19 prevention. We conducted in-depth interviews with 51 people experiencing sheltered and unsheltered homelessness in Atlanta, Georgia during May 2020 to August 2020 to (1) describe challenges and opportunities related to hand hygiene and (2) assess hand hygiene communication preferences. The primary hand hygiene barrier reported was limited access to facilities and supplies, which has disproportionately impacted people experiencing unsheltered homelessness. This lack of access has reportedly been exacerbated during COVID-19 by the closure of public facilities and businesses. Increased access to housing and employment were identified as long-term solutions to improving hand hygiene. Overall, participants expressed a preference for access to facilities and supplies over hand hygiene communication materials. |
National and State-Specific Estimates of Settings of Receiving Human Papillomavirus Vaccination Among Adolescents in the United States
Lu PJ , Yankey D , Fredua B , Hung MC , Walker TY , Markowitz LE , Elam-Evans LD . J Adolesc Health 2021 69 (4) 597-603 PURPOSE: Human papillomavirus (HPV) vaccination in the United States has been recommended for girls since 2006 and for boys since 2011. However, settings of receiving HPV vaccination have not been assessed. The purpose of this study is to assess settings of receiving HPV vaccination among adolescents in order to understand what strategies are needed to improve vaccination uptake. METHODS: Data from the 2018 National Immunization Survey-Teen (NIS-Teen) were analyzed to assess place of HPV vaccination overall, and by gender, quarter, and other selected variables among adolescents in the United States. The 2016-2018 NIS-Teen data were combined to assess state-specific place of HPV vaccination. RESULTS: Among vaccinated adolescents aged 13-17 years, a doctor's office was the most common place where HPV vaccination was received (79.2%), followed by clinics, health centers, or other medical facilities (13.5%), health department (4.1%), hospital or emergency room (2.3%), schools (.5%), and pharmacies or stores (.4%). Overall, 99.1% of adolescents aged 13-17 years received HPV vaccination at medical settings and only .9% at nonmedical settings. Reported vaccination in nonmedical settings by state ranged from less than .1% in Delaware, Florida, and New Hampshire to 4.1% in North Dakota, with a median of 1.0%. CONCLUSIONS: Doctor's offices were the most common medical setting for adolescents to receive HPV vaccination. Less than 1% of adolescents received vaccination at nonmedical settings. Continuing work with medical and nonmedical settings to identify and implement appropriate strategies are needed to improve HPV vaccination coverage among adolescents. |

JAMA Neurol 2021 78 (5) 536-547 ![]() IMPORTANCE: Coronavirus disease 2019 (COVID-19) affects the nervous system in adult patients. The spectrum of neurologic involvement in children and adolescents is unclear. OBJECTIVE: To understand the range and severity of neurologic involvement among children and adolescents associated with COVID-19. SETTING, DESIGN, AND PARTICIPANTS: Case series of patients (age <21 years) hospitalized between March 15, 2020, and December 15, 2020, with positive severe acute respiratory syndrome coronavirus 2 test result (reverse transcriptase-polymerase chain reaction and/or antibody) at 61 US hospitals in the Overcoming COVID-19 public health registry, including 616 (36%) meeting criteria for multisystem inflammatory syndrome in children. Patients with neurologic involvement had acute neurologic signs, symptoms, or diseases on presentation or during hospitalization. Life-threatening involvement was adjudicated by experts based on clinical and/or neuroradiologic features. EXPOSURES: Severe acute respiratory syndrome coronavirus 2. MAIN OUTCOMES AND MEASURES: Type and severity of neurologic involvement, laboratory and imaging data, and outcomes (death or survival with new neurologic deficits) at hospital discharge. RESULTS: Of 1695 patients (909 [54%] male; median [interquartile range] age, 9.1 [2.4-15.3] years), 365 (22%) from 52 sites had documented neurologic involvement. Patients with neurologic involvement were more likely to have underlying neurologic disorders (81 of 365 [22%]) compared with those without (113 of 1330 [8%]), but a similar number were previously healthy (195 [53%] vs 723 [54%]) and met criteria for multisystem inflammatory syndrome in children (126 [35%] vs 490 [37%]). Among those with neurologic involvement, 322 (88%) had transient symptoms and survived, and 43 (12%) developed life-threatening conditions clinically adjudicated to be associated with COVID-19, including severe encephalopathy (n = 15; 5 with splenial lesions), stroke (n = 12), central nervous system infection/demyelination (n = 8), Guillain-Barré syndrome/variants (n = 4), and acute fulminant cerebral edema (n = 4). Compared with those without life-threatening conditions (n = 322), those with life-threatening neurologic conditions had higher neutrophil-to-lymphocyte ratios (median, 12.2 vs 4.4) and higher reported frequency of D-dimer greater than 3 μg/mL fibrinogen equivalent units (21 [49%] vs 72 [22%]). Of 43 patients who developed COVID-19-related life-threatening neurologic involvement, 17 survivors (40%) had new neurologic deficits at hospital discharge, and 11 patients (26%) died. CONCLUSIONS AND RELEVANCE: In this study, many children and adolescents hospitalized for COVID-19 or multisystem inflammatory syndrome in children had neurologic involvement, mostly transient symptoms. A range of life-threatening and fatal neurologic conditions associated with COVID-19 infrequently occurred. Effects on long-term neurodevelopmental outcomes are unknown. |
Characterization of Reference Materials for Spinal Muscular Atrophy Genetic Testing: A GeT-RM Collaborative Project.
Prior TW , Bayrak-Toydemir P , Lynnes TC , Mao R , Metcalf JD , Muralidharan K , Iwata-Otsubo A , Pham HT , Pratt VM , Qureshi S , Requesens D , Shen J , Vetrini F , Kalman L . J Mol Diagn 2020 23 (1) 103-110 ![]() Spinal muscular atrophy (SMA) is an autosomal recessive disorder predominately caused by bi-allelic loss of the SMN1 gene. Increased copies of SMN2, a low functioning nearly identical paralog, is associated with a less severe phenotype. SMA was recently recommended for inclusion in newborn screening. Clinical laboratories must accurately measure SMN1 and SMN2 copy number to identify SMA patients, carriers, and to identify individuals likely to benefit from therapeutic interventions. Having publicly available and appropriately characterized reference materials with various combinations of SMN1 and SMN2 copy number variants is critical to assure accurate SMA clinical testing. To address this need, the Centers for Disease Control and Prevention based Genetic Testing Reference Material Coordination Program (GeT-RM), in collaboration with members of the genetic testing community and the Coriell Institute for Medical Research, have characterized 15 SMA reference materials derived from publicly available cell lines. DNA samples were distributed to four volunteer testing laboratories for genotyping using 3 different methods. The characterized samples had 0-4 copies of SMN1 and 0-5 copies SMN2. The samples also contained clinically important allele combinations (eg. 0 copies SMN1, 3 copies SMN2), and several had markers indicative of a SMA carrier. These and other reference materials characterized by the GeT-RM will support the quality of clinical laboratory testing and are available from the Coriell Institute. |
Rural, urban, and suburban differences in influenza vaccination coverage among children
Zhai Y , Santibanez TA , Kahn KE , Srivastav A , Walker TY , Singleton JA . Vaccine 2020 38 (48) 7596-7602 Influenza vaccination is the primary way to prevent influenza, yet influenza vaccination coverage remains low in the United States. Previous studies have shown that children residing in rural areas have less access to healthcare and lower vaccination coverage for some vaccines. Influenza vaccination coverage among children 6 months-17 years by rural/urban residence during the 2011-12 through 2018-19 influenza seasons was examined using National Immunization Survey-Flu data. The Council of American Survey Research Organizations response rates for National Immunization Survey-Flu ranged from 48% to 65% (2011-12 through the 2017-18 seasons) for the landline sample and 20%-39% (2011-12 through the 2018-19 seasons) for the cellular telephone sample. Children residing in rural areas had influenza vaccination coverage that ranged from 7.9 (2012-13 season) to 12.6 (2016-17 season) percentage points lower than children residing in urban areas, and ranged from 4.5 (2012-13 season) to 7.4 (2016-17 season) percentage points lower than children residing in suburban areas. The differences in influenza vaccination coverage among rural, suburban, and urban children were consistent over the eight seasons studied. Lower influenza vaccination coverage was observed among rural children regardless of child's age, mother's education, household income, or number of children under 18 years of age in the household. Rural versus urban and suburban differences in influenza vaccination coverage remained statistically significant while adjusting for selected sociodemographic characteristics. A better understanding of the reasons for lower childhood influenza vaccination coverage for children in rural and suburban areas is needed. |
Biomechanical assessment while using production tables on mast climbing work platforms
Pan CS , Ning X , Wimer B , Zwiener J , Kau TY . Appl Ergon 2020 90 103276 The objective of this study was to assess the impact of using alternative mast climbing work platform (MCWP) designs on trunk motion and postural stability with masonry workers while performing bricklaying and stepping down tasks using a conventional MCWP setting (i.e. with a step deck) as well as two types of production tables (straight- and L-shaped). The trunk angles and postural sway parameters of twenty-five masonry workers were recorded for the following tasks: (1) standing on a simulated MCWP and laying bricks on an adjacent wall, and (2) stepping down onto the step deck to get into position for doing the bricklaying task. Results indicated that the use of the L-shaped production table resulted in the lowest trunk ranges of motion and significantly reduced the workers' trunk angles in all three planes when compared to both the straight-shaped production table and the conventional approach of not using a production table. Data showed that both body sway velocity and area were significantly reduced when using either one of the production tables. The use of production tables significantly reduced impact sway forces when workers stepped from the main platform to the step deck. The use of production tables on MCWPs improved workers' postures and overall stability, which could reduce the risk of injury. |

Int J Mol Sci 2019 20 (24) Laser printer-emitted nanoparticles (PEPs) generated from toners during printing represent one of the most common types of life cycle released particulate matter from nano-enabled products. Toxicological assessment of PEPs is therefore important for occupational and consumer health protection. Our group recently reported exposure to PEPs induces adverse cardiovascular responses including hypertension and arrythmia via monitoring left ventricular pressure and electrocardiogram in rats. This study employed genome-wide mRNA and miRNA profiling in rat lung and blood integrated with metabolomics and lipidomics profiling in rat serum to identify biomarkers for assessing PEPs-induced disease risks. Whole-body inhalation of PEPs perturbed transcriptional activities associated with cardiovascular dysfunction, metabolic syndrome, and neural disorders at every observed time point in both rat lung and blood during the 21 days of exposure. Furthermore, the systematic analysis revealed PEPs-induced transcriptomic changes linking to other disease risks in rats, including diabetes, congenital defects, auto-recessive disorders, physical deformation, and carcinogenesis. The results were also confirmed with global metabolomics profiling in rat serum. Among the validated metabolites and lipids, linoleic acid, arachidonic acid, docosahexanoic acid, and histidine showed significant variation in PEPs-exposed rat serum. Overall, the identified PEPs-induced dysregulated genes, molecular pathways and functions, and miRNA-mediated transcriptional activities provide important insights into the disease mechanisms. The discovered important mRNAs, miRNAs, lipids and metabolites may serve as candidate biomarkers for future occupational and medical surveillance studies. To the best of our knowledge, this is the first study systematically integrating in vivo, transcriptomics, metabolomics, and lipidomics to assess PEPs inhalation exposure-induced disease risks using a rat model. |
Trends in human papillomavirus (HPV) vaccination initiation among adolescents aged 13-17 by metropolitan statistical area (MSA) status, National Immunization Survey - Teen, 2013 - 2017
Walker TY , Elam-Evans LD , Williams CL , Fredua B , Yankey D , Markowitz LE , Stokley S . Hum Vaccin Immunother 2019 16 (3) 1-8 Disparities in HPV vaccination coverage by metropolitan statistical area (MSA) status were observed in the 2016 and 2017 National Immunization Survey - Teen (NIS-Teen). In 2017, HPV vaccination initiation (>/=1dose) coverage was 11 percentage points lower for adolescents living in non-MSAs (mostly rural areas) and 7 percentage points lower among those living in MSA, non-principal cities (suburban areas) compared to those living in MSA, principal cities (mostly urban areas). In order to understand how this disparity has changed over time, we examined trends in HPV vaccine initiation by MSA status from 2013 to 2017. Weighted linear regression by survey year was used to estimate annual percentage point changes in HPV vaccination initiation. The five-year average annual percentage point increases in HPV vaccination initiation coverage were 5.2 in mostly urban areas, 4.9 for suburban areas, and 5.2 for mostly rural areas. Despite increases in each MSA area, coverage in mostly rural areas was consistently and significantly lower than coverage in mostly urban areas. Coverage was significantly lower among teens living in mostly rural areas regardless of poverty status, sex, and race/ethnicity except among black, non-Hispanic adolescents. There was no significant change in the magnitude of the disparity between mostly urban areas and mostly rural areas over time (p = .98). A better understanding of the facilitators and barriers to HPV vaccination in mostly rural areas is needed to identify and implement targeted strategies to improve HPV vaccination coverage and reduce these disparities. |
Factors associated with not receiving HPV vaccine among adolescents by metropolitan statistical area status, United States, National Immunization Survey-Teen, 2016-2017
Williams CL , Walker TY , Elam-Evans LD , Yankey D , Fredua B , Saraiya M , Stokley S . Hum Vaccin Immunother 2019 16 (3) 562-572 The 2016 and 2017 National Immunization Surveys-Teen (NIS-Teen) highlighted disparities in human papillomavirus (HPV) vaccination coverage by metropolitan statistical area (MSA) status. Coverage with >/=1 dose of HPV vaccine was significantly lower among teens in suburban and mostly- rural areas than it was among those in mostly-urban areas. Reasons underlying this disparity are poorly understood; this analysis sought to identify sociodemographic factors associated with not initiating the HPV vaccine series and to determine whether these factors differed by MSA status. Using NIS-Teen data for a sample of 41,424 adolescents from the 2016 and 2017 survey years, multivariate logistic regression was utilized to assess associations between various sociodemographic factors and non-initiation of the HPV vaccine series by MSA status. Adjusted prevalence ratios and 95% confidence intervals are reported. A secondary analysis assessed missed opportunities for HPV vaccination by MSA status and estimated what coverage could be if these missed opportunities had not occurred. Most factors associated with not receiving HPV vaccine were similar across all three MSAs, including living in the South, having a mother with some college education, not having an 11-12 year old well-child visit, and not receiving a provider recommendation for vaccination. Others were associated with non-initiation of the HPV vaccine series in only specific MSAs. Teens in suburban areas (82.2%) were more likely to miss opportunities for HPV vaccination than those in mostly-urban (79.3%) areas. Coverage with >/=1 dose of HPV vaccine in all three MSAs would be substantially higher if these missed opportunities had been eliminated. |
National, regional, state, and selected local area vaccination coverage among adolescents aged 13-17 years - United States, 2018
Walker TY , Elam-Evans LD , Yankey D , Markowitz LE , Williams CL , Fredua B , Singleton JA , Stokley S . MMWR Morb Mortal Wkly Rep 2019 68 (33) 718-723 The Advisory Committee on Immunization Practices (ACIP) recommends routine vaccination of persons aged 11-12 years to protect against certain diseases, including human papillomavirus (HPV)-associated cancers, meningococcal disease, and pertussis (1). A booster dose of quadrivalent meningococcal conjugate vaccine (MenACWY) is recommended at age 16 years, and serogroup B meningococcal vaccine (MenB) may be administered to persons aged 16-23 years (1). To estimate vaccination coverage among adolescents in the United States, CDC analyzed data from the 2018 National Immunization Survey-Teen (NIS-Teen) which included 18,700 adolescents aged 13-17 years.* During 2017-2018, coverage with >/=1 dose of HPV vaccine increased from 65.5% to 68.1%, and the percentage of adolescents up-to-date(dagger) with the HPV vaccine series increased from 48.6% to 51.1%, although the increases were only observed among males. Vaccination coverage increases were also observed for >/=1 MenACWY dose (from 85.1% to 86.6%) and >/=2 MenACWY doses (from 44.3% to 50.8%). Coverage with tetanus and reduced diphtheria toxoids and acellular pertussis vaccine (Tdap) remained stable at 89%. Disparities in coverage by metropolitan statistical area (MSA)( section sign) and health insurance status identified in previous years persisted (2). Coverage with >/=1 dose of HPV vaccine was higher among adolescents whose parents reported receiving a provider recommendation; however, prevalence of parents reporting receiving a recommendation for adolescent HPV vaccination varied by state (range = 60%-91%). Supporting providers to give strong recommendations and effectively address parental concerns remains a priority, especially in states and rural areas where provider recommendations were less commonly reported. |
One hypervirulent clone, sequence type 283, accounts for a large proportion of invasive Streptococcus agalactiae isolated from humans and diseased tilapia in Southeast Asia.

PLoS Negl Trop Dis 2019 13 (6) e0007421 ![]() BACKGROUND: In 2015, Singapore had the first and only reported foodborne outbreak of invasive disease caused by the group B Streptococcus (GBS; Streptococcus agalactiae). Disease, predominantly septic arthritis and meningitis, was associated with sequence type (ST)283, acquired from eating raw farmed freshwater fish. Although GBS sepsis is well-described in neonates and older adults with co-morbidities, this outbreak affected non-pregnant and younger adults with fewer co-morbidities, suggesting greater virulence. Before 2015 ST283 had only been reported from twenty humans in Hong Kong and two in France, and from one fish in Thailand. We hypothesised that ST283 was causing region-wide infection in Southeast Asia. METHODOLOGY/PRINCIPAL FINDINGS: We performed a literature review, whole genome sequencing on 145 GBS isolates collected from six Southeast Asian countries, and phylogenetic analysis on 7,468 GBS sequences including 227 variants of ST283 from humans and animals. Although almost absent outside Asia, ST283 was found in all invasive Asian collections analysed, from 1995 to 2017. It accounted for 29/38 (76%) human isolates in Lao PDR, 102/139 (73%) in Thailand, 4/13 (31%) in Vietnam, and 167/739 (23%) in Singapore. ST283 and its variants were found in 62/62 (100%) tilapia from 14 outbreak sites in Malaysia and Vietnam, in seven fish species in Singapore markets, and a diseased frog in China. CONCLUSIONS: GBS ST283 is widespread in Southeast Asia, where it accounts for a large proportion of bacteraemic GBS, and causes disease and economic loss in aquaculture. If human ST283 is fishborne, as in the Singapore outbreak, then GBS sepsis in Thailand and Lao PDR is predominantly a foodborne disease. However, whether transmission is from aquaculture to humans, or vice versa, or involves an unidentified reservoir remains unknown. Creation of cross-border collaborations in human and animal health are needed to complete the epidemiological picture. |
