Prevalence and predictors of colon and prostate cancer screening among volunteer firefighters: The United States Firefighter Cancer Assessment and Prevention Study
Shah NN , Steinberg MB , Calkins MM , Caban-Martinez AJ , Burgess JL , Austin E , Hollerbach BS , Edwards DL , Black TM , Black K , Hinton KM , Kubiel BS , Graber JM . Am J Ind Med 2024 BACKGROUND: Although firefighters have increased risk for colon and prostate cancer, limited information exists on screening practices for these cancers in volunteer firefighters who compose two-thirds of the US fire service. We estimated the prevalence of colon and prostate cancer screening among volunteer firefighters using eligibility criteria from 4 evidence-based screening recommendations and evaluated factors influencing screening. METHODS: We evaluated colon (n = 569) and prostate (n = 498) cancer screening prevalence in a sample of US volunteer firefighters using eligibility criteria from the US Preventive Services Taskforce (USPSTF), National Fire Protection Association, American Cancer Society, and National Comprehensive Cancer Network. We assessed associations with fire service experience, demographics, and cancer risk perception based on USPSTF guidelines. RESULTS: For those eligible based on USPSTF guidelines, colon and prostate cancer screening prevalence was 51.7% (95% CI: 45.7, 57.8) and 48.8% (95% CI: 40.0, 57.6), respectively. Higher odds of colon and prostate cancer screening were observed with older age and with some college education compared to those with less education. Fire service experience and cancer risk perception were not associated with screening practices. CONCLUSION: This is the first large study to assess colon and prostate cancer screening among US volunteer firefighters based on different screening guidelines. Our findings suggest gaps in cancer prevention efforts in the US volunteer fire service. Promoting cancer screening education and opportunities for volunteer firefighters by their fire departments, healthcare professionals, and public health practitioners, may help to address the gaps. |
CDC Grand Rounds: Newborn screening and improved outcomes.
Howell RR , Terry S , Tait VF , Olney R , Hinton CF , Grosse S , Eichwald J , Cuthbert C , Popovic T , Glidewell J . MMWR Morb Mortal Wkly Rep 2012 61 (21) 390-3 Newborn screening is the practice of testing every newborn for certain harmful or potentially fatal conditions, such as hearing loss and certain genetic, endocrine, and metabolic disorders that typically are not otherwise apparent at birth. Newborn screening in the United States began in the 1960s. Universal newborn screening has become a well-established, state-based, public health system involving education, screening, diagnostic follow-up, treatment and management, and system monitoring and evaluation. Each year, >98% of approximately 4 million newborns in the United States are screened. Through early identification, newborn screening provides an opportunity for treatment and significant reductions in morbidity and mortality. |
Vibrio species: development of EUCAST susceptibility testing methods and MIC and zone diameter distributions on which to determine clinical breakpoints
Karatuna O , Matuschek E , Åhman J , Caidi H , Kahlmeter G . J Antimicrob Chemother 2023 OBJECTIVES: Most human infections caused by Vibrio spp. do not warrant antimicrobial treatment but in severe cases, targeted antimicrobial treatment can be lifesaving. For Vibrio spp., standardized antimicrobial susceptibility testing (AST) guidelines with EUCAST methodology are lacking. In this study, we aimed to produce data suitable for EUCAST to establish clinical MIC breakpoints and zone diameter correlates for Vibrio spp. METHODS: An intercontinental collection (Nā=ā524) comprising five important Vibrio spp. (V. alginolyticus, V. cholerae, V. fluvialis, V. parahaemolyticus and V. vulnificus) was organized. All isolates were subjected to broth microdilution (BMD) against 11 antimicrobial agents according to ISO 20776-1 using unsupplemented Mueller-Hinton broth on freeze-dried Sensititre panels (Thermo Scientific, UK), and most isolates (nā=ā371) were also tested with disc diffusion according to EUCAST methodology for non-fastidious organisms. RESULTS: Aggregated results were used to generate MIC and zone diameter distributions and to prepare graphs of MIC-zone diameter correlation. Based on these results, the EUCAST Steering Committee determined clinical susceptible (S) and resistant (R) MIC (mg/L) breakpoints (S≤/R>) for the five Vibrio spp. for piperacillin/tazobactam (1/1), cefotaxime (0.25/0.25), ceftazidime (1/1), meropenem (0.5/0.5), ciprofloxacin (0.25/0.25), levofloxacin (0.25/0.25), azithromycin (4/4), doxycycline (0.5/0.5) and trimethoprim/sulfamethoxazole (0.25/0.25). The corresponding zone diameter breakpoints were identified. CONCLUSIONS: We demonstrated the validity of using standard BMD and EUCAST disc diffusion methodology for AST of five Vibrio spp., and generated suitable data to allow EUCAST to determine clinical MIC and zone diameter breakpoints for five pathogenic Vibrio spp., including both non-toxigenic and toxigenic V. cholerae. |
Antimicrobial Resistance Laboratory Network's multisite evaluation of the ThermoFisher Sensititre GN7F broth microdilution panel for antimicrobial susceptibility testing
Bhatnagar AS , Machado MJ , Patterson L , Anderson K , Abelman RL , Bateman A , Biggs A , Bumpus-White P , Craft B , Howard M , LaVoie SP , Lonsway D , Sabour S , Schneider A , Snippes-Vagnone P , Tran M , Torpey D , Valley A , Elkins CA , Karlsson M , Brown AC . J Clin Microbiol 2023 61 (12) e0079923 In 2017, the Centers for Disease Control and Prevention (CDC) established the Antimicrobial Resistance Laboratory Network to improve domestic detection of multidrug-resistant organisms. CDC and four laboratories evaluated a commercial broth microdilution panel. Antimicrobial susceptibility testing using the Sensititre GN7F (ThermoFisher Scientific, Lenexa, KS) was evaluated by testing 100 CDC and Food and Drug Administration AR Isolate Bank isolates [40 Enterobacterales (ENT), 30 Pseudomonas aeruginosa (PSA), and 30 Acinetobacter baumannii (ACB)]. We assessed multiple amounts of transfer volume (TV) between the inoculum and tubed 11-mL cation-adjusted Mueller-Hinton broth: 1 µL [tribe Proteeae (P-tribe) only] and 10, 30, and 50 µL, resulting in respective CFU per milliter of 1 × 10(4), 1 × 10(5), 3 × 10(5), and 5 × 10(5). Four TV combinations were analyzed: standard (STD) [1 µL (P-tribe) and 10 µL], enhanced standard (E-STD) [1 µL (P-tribe) and 30 µL], 30 µL, and 50 µL. Essential agreement (EA), categorical agreement, major error (ME), and very major error (VME) were analyzed by organism then TVs. For ENT, the average EA across laboratories was <90% for 7 of 15 β-lactams using STD and E-STD TVs. As TVs increased, EA increased (>90%), and VMEs decreased. For PSA, EA improved as TVs increased; however, MEs also increased. For ACB, increased TVs provided slight EA improvements; all TVs yielded multiple VMEs and MEs. For ENT and ACB, Minimum inhibitory concentrations (MICs) trended downward using a 1 or 10 µL TV; there were no obvious MIC trends by TV for PSA. The public health and clinical consequences of missing resistance warrant increased TV of 30 µL for the GN7F, particularly for P-tribe, despite being considered "off-label" use. |
Gene flux and acid-imposed selection are the main drivers of antimicrobial resistance in broiler chicks infected with Salmonella enterica serovar Heidelberg (preprint)
Oladeinde A , Abdo Z , Press MO , Cook K , Cox NA , Zwirzitz B , Woyda R , Lakin SM , Thomas JCIV , Looft T , Cosby DE , Hinton AJr , Guard J , Line E , Rothrock MJ , Berrang ME , Herrington K , Zock G , Plumblee Lawrence J , Cudnik D , House S , Ingram K , Lariscy L , Wagner M , Aggrey SE , Chai L , Ritz C . bioRxiv 2021 2021.02.25.432983 Antimicrobial resistance (AR) spread is a worldwide health challenge, stemming in large part, from the ability of microbes to share their genetic material through horizontal gene transfer (HGT). Overuse and misuse of antibiotics in clinical settings and in food production have been linked to this increased prevalence and spread of AR. Consequently, public health and consumer concerns have resulted in a remarkable recent reduction in antibiotics used for food animal production. This is driven by the assumption that removing this selective pressure will favor the recovery of antibiotic susceptible taxa and will limit AR sharing through HGT, allowing the currently available antibiotic arsenal to be effective for a longer period. In this study we used broiler chicks raised antibiotic-free and Salmonella enterica serovar Heidelberg (SH), as a model food pathogen, to test this hypothesis. Our results show that neonatal broiler chicks challenged with an antibiotic susceptible SH strain and raised without antibiotics carried susceptible and multidrug resistance SH strains 14 days after challenge. SH infection perturbed the microbiota of broiler chicks and gavaged chicks acquired antibiotic resistant SH at a higher rate. We determined that the acquisition of a plasmid from commensal Escherichia coli population conferred multidrug resistance phenotype to SH recipients and carriage of this plasmid increased the fitness of SH under acidic selection pressure. These results suggest that HGT of AR shaped the evolution of SH and that antibiotic use reduction alone is insufficient to limit antibiotic resistance transfer from commensal bacteria to Salmonella.Importance The reported increase in antibiotic resistant bacteria in humans have resulted in a major shift away from antibiotics use in food animal production. This has been driven by the assumption that removing antibiotics will select for antibiotic susceptible bacterial taxa, and this in turn will allow the currently available antibiotic arsenal to be more effective. This shift in practice has highlighted new questions that need to be answered to assess the effectiveness of antibiotic removal in reducing the spread of antibiotic resistance bacteria. This research demonstrates that antibiotic susceptible Salmonella Heidelberg strains can acquire multidrug resistance from commensal bacteria present in the gut of neonatal broiler chicks, even in the absence of antibiotic selection. We demonstrate that exposure to acidic pH drove the horizontal transfer of antimicrobial resistance plasmids and suggests that simply removing antibiotics from food-animal production might not be sufficient to limit the spread of antimicrobial resistance.Competing Interest StatementThe authors have declared no competing interest. |
Optical microscopy reveals the dynamic nature of B. pseudomallei morphology during β-lactam antimicrobial susceptibility testing (preprint)
McLaughlin HP , Bugrysheva J , Sue D . bioRxiv 2020 2020.01.13.904995 Background In Gram-negative species, β-lactam antibiotics target penicillin binding proteins (PBPs) resulting in morphological alterations of bacterial cells. Observations of antibiotic-induced cell morphology changes can rapidly and accurately differentiate drug susceptible from resistant bacterial strains; however, resistant cells do not always remain unchanged. Burkholderia pseudomallei is a Gram-negative, biothreat pathogen and the causative agent of melioidosis, an often fatal infectious disease for humans.Results Here, we identified β-lactam targets in B. pseudomallei by in silico analysis. Ten genes encoding putative PBPs, including PBP-1, PBP-2, PBP-3 and PBP-6, were detected in the genomes of susceptible and resistant strains. Real-time, live-cell imaging of B. pseudomallei strains demonstrated dynamic morphological changes in broth containing clinically relevant β-lactam antibiotics. At sub-inhibitory concentrations of ceftazidime (CAZ), amoxicillin-clavulanic acid (AMC), and imipenem (IPM), filamentation, varying in length and proportion, was an initial response of the multidrug-resistant strain Bp1651 in exponential phase. However, a dominant morphotype reemerged during stationary phase that resembled cells unexposed to antibiotics. Similar morphology dynamics were observed for AMC-resistant strains, MSHR1655 and 724644, when exposed to sub-inhibitory concentrations of AMC. For all B. pseudomallei strains evaluated, increased exposure time and exposure to increased concentrations of AMC at and above minimal inhibitory concentrations (MICs) in broth resulted in cell morphology shifts from filaments to spheroplasts and/or cell lysis. B. pseudomallei morphology changes were more consistent in IPM. Spheroplast formation followed by cell lysis was observed for all strains in broth containing IPM at concentrations greater than or equal to MICs, however, the time to cell lysis was variable. Length of B. pseudomallei cells was strain-, drug- and drug concentration-dependent.Conclusions Both resistant and susceptible B. pseudomallei strains exhibited filamentation during early exposure to AMC and CAZ at concentrations used to interpret susceptibility (based on CLSI guidelines). While developing a rapid β-lactam antimicrobial susceptibility test based on cell-shape alone requires more extensive analyses, optical microscopy detected B. pseudomallei growth attributes that lend insight into antibiotic response and antibacterial mechanisms of action.(AST)Antimicrobial susceptibility test,(BMD)broth microdilution,(CLSI)Clinical and Laboratory Standards Institute,(IPM)imipenem,(CAZ)ceftazidime,(AMC)amoxicillin-clavulanic acid,(MDR)multidrug-resistant,(R)resistant,(I)intermediate,(S)susceptible,(SBA)Trypticase Soy Agar II with 5% sheep blood,(CAMHB)cation-adjusted Mueller Hinton broth,(MIC)minimal inhibitory concentrations,(TES)N-tris(hydroxymethyl) methyl-2-aminoethanesulfonic acid,(SESA)Segmentation and Extraction Surface Area,(SD)standard deviation,(PBPs)penicillin-binding proteins. |
Progress in expanding newborn screening in the United States
Grosse SD , Cuthbert C , Gaffney M , Gaviglio A , Hinton CF , Kellar-Guenther Y , Kemper AR , McKasson S , Ojodu J , Riley C , Singh S , Sontag MK , Shapira SK . Am J Hum Genet 2023 110 (6) 1015-1016 We read with interest the recent article by Kingsmore et al., who suggest that universal newborn rapid whole-genome sequencing is attractive for “comprehensive” newborn screening (NBS).1 Existing US NBS programs are based on mandated routine testing of newborns; evidence-based decision-making processes exist for this testing.2 Whether policy makers also consider routine rapid whole-genome sequencing of newborns to be warranted may depend on the resolution of a number of evidentiary, ethical, legal, social, and economic issues.3 Kingsmore et al. suggest that sequencing can complement existing public-health NBS programs but acknowledge the challenge of reconciling universal or near-universal genomic screening with informed parental consent and the allowable secondary use of genomic information.1 |
Public-private partnerships to lower the risk of diabetes among black women using cooperative agreements: The National Diabetes Prevention Program and the black women's health imperative
Williams A , Ford A , Webb M , Knight M , Costa K , Hinton C . J Womens Health (Larchmt) 2022 31 (8) 1079-1083 The National Diabetes Prevention Program (National DPP) is a partnership of public and private organizations working to build a nationwide delivery system for a lifestyle change program (LCP), which is proved to prevent or delay onset of type 2 diabetes in adults with prediabetes. Through this program, the Centers for Disease Control and Prevention (CDC) establishes partnerships with organizations to prevent or delay the onset of type 2 diabetes by using the evidence-based and audience-tailored LCP. The DP17-1705 cooperative agreement aims to expand the reach of the program in underserved areas and to populations currently underrepresented in the program relative to their risk. This article highlights a successful adaptation of the National DPP PreventT2 curriculum to address the needs of women who are Black funded by this cooperative agreement. The Change your Lifestyle, Change your Life (CYL(2)) program resulted from a partnership between CDC and the Black Women's Health Imperative. Successes and challenges associated with this program are highlighted. Lessons learned from these efforts can be used by practitioners to inform future type 2 diabetes prevention initiatives. |
Epidemiologically Linked COVID-19 Outbreaks at a Youth Camp and Men's Conference - Illinois, June-July 2021.
Matthias J , Patrick S , Wiringa A , Pullman A , Hinton S , Campos J , Belville T , Sinner Mph M , Buchanan TT , Sim B , Goldesberry KE . MMWR Morb Mortal Wkly Rep 2021 70 (35) 1223-1227 On June 30, 2021, the Illinois Department of Public Health (IDPH) contacted CDC concerning COVID-19 outbreaks at two events sponsored by the same organization: a 5-day overnight church camp for persons aged 14-18 years and a 2-day men's conference. Neither COVID-19 vaccination nor COVID-19 testing was required before either event. As of August 13, a total of 180 confirmed and probable cases had been identified among attendees at the two events and their close contacts. Among the 122 cases associated with the camp or the conference (primary cases), 18 were in persons who were fully vaccinated, with 38 close contacts. Eight of these 38 close contacts subsequently became infected with SARS-CoV-2, the virus that causes COVID-19 (secondary cases); among the eight close contacts with secondary cases, one half (four) were fully vaccinated. Among the 180 total persons with outbreak-associated cases, five (2.8%) were hospitalized; no deaths occurred. None of the vaccinated persons with cases were hospitalized. Approximately 1,000 persons across at least four states were exposed to SARS-CoV-2 through attendance at these events or through close contact with a person who had a primary case. This investigation underscores the impact of secondary SARS-CoV-2 transmission during large events, such as camps and conferences, when COVID-19 prevention strategies are not implemented. In Los Angeles County, California, during July 2021, when the SARS-CoV-2 B.1.617.2 (Delta) variant was predominant, unvaccinated residents were five times more likely to be infected and 29 times more likely to be hospitalized from infection than were vaccinated residents (1). Implementation of multiple prevention strategies, including vaccination and nonpharmaceutical interventions such as masking, physical distancing, and screening testing, are critical to preventing SARS-CoV-2 transmission and serious complications from COVID-19. |
Horizontal Gene Transfer Is the Main Driver of Antimicrobial Resistance in Broiler Chicks Infected with Salmonella enterica Serovar Heidelberg.
Oladeinde A , Abdo Z , Press MO , Cook K , Cox NA , Zwirzitz B , Woyda R , Lakin SM , Thomas JC4th , Looft T , Cosby DE , Hinton AJr , Guard J , Line E , Rothrock MJ , Berrang ME , Herrington K , Zock G , Plumblee Lawrence J , Cudnik D , House S , Ingram K , Lariscy L , Wagner M , Aggrey SE , Chai L , Ritz C . mSystems 2021 6 (4) e0072921 The overuse and misuse of antibiotics in clinical settings and in food production have been linked to the increased prevalence and spread of antimicrobial resistance (AR). Consequently, public health and consumer concerns have resulted in a remarkable reduction in antibiotics used for food animal production. However, there are no data on the effectiveness of antibiotic removal in reducing AR shared through horizontal gene transfer (HGT). In this study, we used neonatal broiler chicks and Salmonella enterica serovar Heidelberg, a model food pathogen, to test if chicks raised antibiotic free harbor transferable AR. We challenged chicks with an antibiotic-susceptible S. Heidelberg strain using various routes of inoculation and determined if S. Heidelberg isolates recovered carried plasmids conferring AR. We used antimicrobial susceptibility testing and whole-genome sequencing (WGS) to show that chicks grown without antibiotics harbored an antimicrobial resistant S. Heidelberg population at 14 days after challenge and chicks challenged orally acquired AR at a higher rate than chicks inoculated via the cloaca. Using 16S rRNA gene sequencing, we found that S. Heidelberg infection perturbed the microbiota of broiler chicks, and we used metagenomics and WGS to confirm that a commensal Escherichia coli population was the main reservoir of an IncI1 plasmid acquired by S. Heidelberg. The carriage of this IncI1 plasmid posed no fitness cost to S. Heidelberg but increased its fitness when exposed to acidic pH in vitro. These results suggest that HGT of plasmids carrying AR shaped the evolution of S. Heidelberg and that antibiotic use reduction alone is insufficient to limit antibiotic resistance transfer from commensal bacteria to Salmonella enterica. IMPORTANCE The reported increase in antibiotic-resistant bacteria in humans has resulted in a major shift away from antibiotic use in food animal production. This shift has been driven by the assumption that removing antibiotics will select for antibiotic susceptible bacterial taxa, which in turn will allow the currently available antibiotic arsenal to be more effective. This change in practice has highlighted new questions that need to be answered to assess the effectiveness of antibiotic removal in reducing the spread of antibiotic resistance bacteria. This research demonstrates that antibiotic-susceptible Salmonella enterica serovar Heidelberg strains can acquire multidrug resistance from commensal bacteria present in the gut of neonatal broiler chicks, even in the absence of antibiotic selection. We demonstrate that exposure to acidic pH drove the horizontal transfer of antimicrobial resistance plasmids and suggest that simply removing antibiotics from food animal production might not be sufficient to limit the spread of antimicrobial resistance. |
Following Patients With Inborn Errors of Metabolism: What Do We Value and How Do We Know
Brosco JP , Hinton CF . Pediatrics 2021 148 (2) In the current drive to improve health care systems in the United States, “value” has been defined as the ratio of quality to cost. Measuring quality, in turn, relies on the common-sense definition of the word value: what do we find important in life? Agreeing on what we value, and how to measure it, has become a critical research task with implications for health policy and clinical practice. Within the research world, there is a movement to define “core outcome sets” (COSs) or variables that should be included in the results of any clinical trial.1 Reporting such common measures facilitates comparison of and synthesis across studies. COSs can also ensure that researchers focus on what matters to patients and families, as well as to health policy leaders. |
Community Transmission of SARS-CoV-2 Associated with a Local Bar Opening Event - Illinois, February 2021.
Sami S , Turbyfill CR , Daniel-Wayman S , Shonkwiler S , Fisher KA , Kuhring M , Patrick AM , Hinton S , Minor AS , Ricaldi JN , Ezike N , Kauerauf J , Duffus WA . MMWR Morb Mortal Wkly Rep 2021 70 (14) 528-532 During February 2021, an opening event was held indoors at a rural Illinois bar that accommodates approximately 100 persons. The Illinois Department of Public Health (IDPH) and local health department staff members investigated a COVID-19 outbreak associated with this opening event. Overall, 46 COVID-19 cases were linked to the event, including cases in 26 patrons and three staff members who attended the opening event and 17 secondary cases. Four persons with cases had COVID-19-like symptoms on the same day they attended the event. Secondary cases included 12 cases in eight households with children, two on a school sports team, and three in a long-term care facility (LTCF). Transmission associated with the opening event resulted in one school closure affecting 650 children (9,100 lost person-days of school) and hospitalization of one LTCF resident with COVID-19. These findings demonstrate that opening up settings such as bars, where mask wearing and physical distancing are challenging, can increase the risk for community transmission of SARS-CoV-2, the virus that causes COVID-19. As community businesses begin to reopen, a multicomponent approach should be emphasized in settings such as bars to prevent transmission* (1). This includes enforcing consistent and correct mask use, maintaining ≥6 ft of physical distance between persons, reducing indoor bar occupancy, prioritizing outdoor seating, improving building ventilation, and promoting behaviors such as staying at home when ill, as well as implementing contact tracing in combination with isolation and quarantine when COVID-19 cases are diagnosed. |

Clin Infect Dis 2021 73 (4) 631-641 BACKGROUND: The Global Enteric Multicenter Study (GEMS) determined the etiologic agents of moderate-to-severe diarrhea (MSD) in children under 5 years old in Africa and Asia. Here, we describe the prevalence and antimicrobial susceptibility of non-typhoidal Salmonella (NTS) serovars in GEMS and examine the phylogenetics of Salmonella Typhimurium ST313 isolates. METHODS: Salmonella isolated from children with MSD or diarrhea-free controls were identified by classical clinical microbiology and serotyped using antisera and/or whole genome sequence data. We evaluated antimicrobial susceptibility using the Kirby-Bauer disk diffusion method. Salmonella Typhimurium sequence types were determined using multi-locus sequence typing and whole genome sequencing was performed to assess the phylogeny of ST313. RESULTS: Out of 370 Salmonella-positive individuals, 190 (51.4%) were MSD cases and 180 (48.6%) were diarrhea-free controls. The most frequent Salmonella serovars identified were Salmonella Typhimurium, serogroup O:8 (C2-C3), serogroup O:6,7 (C1), Salmonella Paratyphi B Java and serogroup O:4 (B). The prevalence of NTS was low but similar across sites, regardless of age, and was similar amongst both cases and controls except in Kenya, where Salmonella Typhimurium was more commonly associated with cases than controls. Phylogenetic analysis showed that these Salmonella Typhimurium isolates, all ST313, were highly genetically related to isolates from controls. Generally, Salmonella isolates from Asia were resistant to ciprofloxacin and ceftriaxone but African isolates were susceptible to these antibiotics. CONCLUSION: Our data confirms that NTS is prevalent, albeit at low levels, in Africa and South Asia. Our findings provide further evidence that multi-drug resistant Salmonella Typhimurium ST313 can be carried asymptomatically by humans in sub-Saharan Africa. |
Infants with Congenital Disorders Identified Through Newborn Screening - United States, 2015-2017.
Sontag MK , Yusuf C , Grosse SD , Edelman S , Miller JI , McKasson S , Kellar-Guenther Y , Gaffney M , Hinton CF , Cuthbert C , Singh S , Ojodu J , Shapira SK . MMWR Morb Mortal Wkly Rep 2020 69 (36) 1265-1268 Newborn screening (NBS) identifies infants at risk for congenital disorders for which early intervention has been shown to improve outcomes (1). State public health programs are encouraged to screen for disorders on the national Recommended Uniform Screening Panel (RUSP), which increased from 29 disorders in 2005 to 35 in 2018.* The RUSP includes hearing loss (HL) and critical congenital heart defects, which can be detected through point-of-care screening, and 33 disorders detected through laboratory screening of dried blood spot (DBS) specimens. Numbers of cases for 33 disorders on the RUSP (32 DBS disorders and HL) reported by 50 U.S. state programs were tabulated. The three subtypes of sickle cell disease (SCD) listed as separate disorders on the RUSP (S,S disease; S,beta-thalassemia; and S,C disease) were combined for the current analysis, and the frequencies of the resulting disorders were calculated relative to annual births. During 2015-2017, the overall prevalence was 34.0 per 10,000 live births. Applying that frequency to 3,791,712 live births in 2018,(†) approximately 12,900 infants are expected to be identified each year with one of the disorders included in the study. The most prevalent disorder is HL (16.5 per 10,000), and the most prevalent DBS disorders are primary congenital hypothyroidism (CH) (6.0 per 10,000), SCD (4.9 per 10,000), and cystic fibrosis (CF) (1.8 per 10,000). Notable changes in prevalence for each of these disorders have occurred since the previous estimates based on 2006 births (2). The number of infants identified at a national level highlights the effect that NBS programs are having on infant health through early detection, intervention, and potential improved health, regardless of geographic, racial/ethnic, or socioeconomic differences. |
Treatment discontinuation within 3 years of levothyroxine initiation among children diagnosed with congenital hypothyroidism
Kemper AR , Grosse SD , Baker M , Pollock AJ , Hinton CF , Shapira SK . J Pediatr 2020 223 136-140 OBJECTIVES: To measure the rates of thyroid gland imaging and levothyroxine (L-T4) discontinuation and to assess whether discontinuation was monitored with thyroid stimulating hormone (TSH) testing in subjects with congenital hypothyroidism. STUDY DESIGN: This is a retrospective analysis of claims data from the IBM MarketScan Databases for children born during 2010-2016 and continuously enrolled in a non-capitated employer-sponsored private health insurance plan or in Medicaid for >/=36 months from the date of the first filled L-T4 prescription. RESULTS: 263 privately-insured and 241 Medicaid-enrolled children met the inclusion criteria. More privately-insured than Medicaid-enrolled children had imaging between the first filled prescription and 180 days after the last filled prescription (24.3% vs. 12.9%; P = .001). By 36 months, 35.7% discontinued L-T4, with no difference by insurance status (P=0.48). Among those who discontinued, 29.1% of privately-insured children and 47.7% of Medicaid-enrolled children had no claims for TSH testing within the next 180 days (P=0.01). CONCLUSIONS: Nearly one-third of children with suspected CH discontinued L-T4 by 3 years and fewer Medicaid-enrolled than privately-insured children received timely follow-up TSH testing. Future studies are indicated to understand the quality of care and developmental outcomes for children with CH and barriers to guideline adherence in evaluating for transient CH. |
Building children's preparedness capacity at the Centers for Disease Control and Prevention one event at a time, 2009-2018
Leeb RT , Franks JL , Dziuban EJ , Ruben W , Bartenfeld M , Hinton CF , Chatham-Stephens K , Peacock G . Am J Public Health 2019 109 S260-s262 This issue of AJPH highlights the importance of community preparedness for public health emergencies. An essential component of community preparedness is the capacity to address the needs of children, who comprise nearly one quarter of the US population and are particularly vulnerable to disaster-related morbidity and mortality (Figure 1).1 However, communities may not be well equipped to address children’s needs. |
Case definitions for conditions identified by newborn screening public health surveillance
Sontag MK , Sarkar D , Comeau AM , Hassell K , Botto LD , Parad R , Rose SR , Wintergerst KA , Smith-Whitley K , Singh S , Yusuf C , Ojodu J , Copeland S , Hinton CF . Int J Neonatal Screen 2018 4 (2) 16 Newborn screening (NBS) identifies infants with rare conditions to prevent death or the onset of irreversible morbidities. Conditions on the Health and Human Services Secretary's Recommended Uniform Screening Panel have been adopted by most state NBS programs, providing a consistent approach for identification of affected newborns across the United States. Screen-positive newborns are identified and referred for confirmatory diagnosis and follow-up. The designation of a clinically significant phenotype precursor to a clinical diagnosis may vary between clinical specialists, resulting in diagnostic variation. Determination of disease burden and birth prevalence of the screened conditions by public health tracking is made challenging by these variations. This report describes the development of a core group of new case definitions, along with implications, plans for their use, and links to the definitions that were developed by panels of clinical experts. These definitions have been developed through an iterative process and are piloted in NBS programs. Consensus public health surveillance case definitions for newborn screened disorders will allow for consistent categorization and tracking of short- and long-term follow-up of identified newborns at the local, regional, and national levels. |
Enhancing individual and community disaster preparedness: Individuals with disabilities and others with access and functional needs
Kruger J , Hinton CF , Sinclair LB , Silverman B . Disabil Health J 2017 11 (2) 170-173 Preparedness planning is essential to minimizing the impact of disasters on communities and individuals. Attention to the needs of people with disabilities is vital as they have additional needs before, during and after a disaster that are specific to the disabling condition. In this Commentary, we emphasize national guidelines on disability inclusion in emergency preparedness. We examine some potential areas of planning and response that need attention as suggested by preparedness data for people with self-reported disabilities (also referred to as access and functional needs) and highlight selected resources (e.g., tools, trainings, and online webinars) to enhance whole community preparedness and disability inclusion efforts. This Commentary intends to bridge the gap between those various facets of preparedness, at all levels of government and among individuals, with the aim of ensuring that the whole community is prepared to adapt, withstand and rapidly recover from disruptions due to disasters. |
The Guide to Community Preventive Services and disability inclusion
Hinton CF , Kraus LE , Richards TA , Fox MH , Campbell VA . Am J Prev Med 2017 53 (6) 898-903 INTRODUCTION: Approximately 40 million people in the U.S. identify as having a serious disability, and people with disabilities experience many health disparities compared with the general population. The Guide to Community Preventive Services (The Community Guide) identifies evidence-based programs and policies recommended by the Community Preventive Services Task Force (Task Force) to promote health and prevent disease. The Community Guide was assessed to answer the questions: are Community Guide public health intervention recommendations applicable to people with disabilities, and are adaptations required? METHODS: An assessment of 91 recommendations from The Community Guide was conducted for 15 health topics by qualitative analysis involving three data approaches: an integrative literature review (years 1980-2011), key informant interviews, and focus group discussion during 2011. RESULTS: Twenty-six recommended interventions would not need any adaptation to be of benefit to people with disabilities. Forty-one recommended interventions could benefit from adaptations in communication and technology; 33 could benefit from training adaptations; 31 from physical accessibility adaptations; and 16 could benefit from other adaptations, such as written policy changes and creation of peer support networks. Thirty-eight recommended interventions could benefit from one or more adaptations to enhance disability inclusion. CONCLUSIONS: As public health and healthcare systems implement Task Force recommendations, identifying and addressing barriers to full participation for people with disabilities is important so that interventions reach the entire population. With appropriate adaptations, implementation of recommendations from The Community Guide could be successfully expanded to address the needs of people with disabilities. |
Survival disparities associated with congenital diaphragmatic hernia
Hinton CF , Siffel C , Correa A , Shapira SK . Birth Defects Res 2017 109 (11) 816-823 BACKGROUND: We assessed sociodemographic and clinical factors that are associated with survival among infants with congenital diaphragmatic hernia (CDH). METHODS: Using data from the Metropolitan Atlanta Congenital Defects Program, we ascertained 150 infants born with CDH between 1979 and 2003 and followed via linkage with state vital records and the National Death Index. Kaplan-Meier survival probabilities and adjusted hazard ratios (HRs) were calculated for socioeconomic and clinical characteristics. RESULTS: Survival increased from 40 to 62% over the study period. White infants born before 1988 were 2.9 times less likely to survive than those born after 1988. Black infants' survival did not show significant improvement after 1988. White infants' survival was not significantly affected by poverty, whereas black infants born in higher levels of poverty were 2.7 times less likely to survive than black infants born in lower levels of neighborhood poverty. White infants with multiple major birth defects were 2.6 times less likely to survive than those with CDH alone. The presence of multiple defects was not significantly associated with survival among black infants. CONCLUSIONS: Survival among infants and children with CDH has improved over time among whites, but not among blacks. Poverty is associated with lower survival among blacks, but not among whites. The presence of multiple defects is associated with lower survival among whites, but not among blacks. The differential effects of poverty and race should be taken into account when studying disparities in health outcomes. |
A framework for assessing outcomes from newborn screening: on the road to measuring its promise.
Hinton CF , Homer CJ , Thompson AA , Williams A , Hassell KL , Feuchtbaum L , Berry SA , Comeau AM , Therrell BL , Brower A , Harris KB , Brown C , Monaco J , Ostrander RJ , Zuckerman AE , Kaye C , Dougherty D , Greene C , Green NS . Mol Genet Metab 2016 118 (4) 221-9 Newborn screening (NBS) is intended to identify congenital conditions prior to the onset of symptoms in order to provide early intervention that leads to improved outcomes. NBS is a public health success, providing reduction in mortality and improved developmental outcomes for screened conditions. However, it is less clear to what extent newborn screening achieves the long-term goals relating to improved health, growth, development and function. We propose a framework for assessing outcomes for the health and well-being of children identified through NBS programs. The framework proposed here, and this manuscript, were approved for publication by the Secretary of Health and Human Services' Advisory Committee on Heritable Disorders in Newborns and Children (ACHDNC). This framework can be applied to each screened condition within the Recommended Uniform Screening Panel (RUSP), recognizing that the data elements and measures will vary by condition. As an example, we applied the framework to sickle cell disease and phenylketonuria (PKU), two diverse conditions with different outcome measures and potential sources of data. Widespread and consistent application of this framework across state NBS and child health systems is envisioned as useful to standardize approaches to assessment of outcomes and for continuous improvement of the NBS and child health systems. SIGNIFICANCE: Successful interventions for newborn screening conditions have been a driving force for public health newborn screening for over fifty years. Organizing interventions and outcome measures into a standard framework to systematically assess outcomes has not yet come into practice. This paper presents a customizable outcomes framework for organizing measures for newborn screening condition-specific health outcomes, and an approach to identifying sources and challenges to populating those measures. |
Parental presence at the bedside of a child with suspected ebola: an expert discussion
Hinton CF , Davies HD , Hocevar SN , Krug SE , Milstone AM , Ortmann L , Cassell CH , Peacock G , Griese SE . Clin Pediatr Emerg Med 2016 17 (1) 81-86 The Ebola virus disease (Ebola) outbreak in West Africa (2014-2015) prompted domestic planning to address the scenario in which a traveler imports Ebola into the United States. Parental presence at the bedside of a child with suspected or confirmed Ebola emerged as a challenging issue for pediatric health care providers and public health practitioners. At the heart of the issue was the balance of family-centered care and appropriate infection control, which are not easily aligned in the setting of Ebola. In the following dialogue, pediatricians, who participated in discussions about parental presence during the evaluation of pediatric persons under investigation, and a public health ethicist discuss the interplay between family-centered care and appropriate infection control. Reaching a balance between the 2 ideals is difficult and may require the facility and providers to engage in a deliberate conversation to determine how they will handle parental presence for such high-risk scenarios, including Ebola and other high-consequence pathogens, in their institution. © 2016 Elsevier Inc. |
CDC Grand Rounds: addressing preparedness challenges for children in public health emergencies
Hinton CF , Griese SE , Anderson MR , Chernak E , Peacock G , Thorpe PG , Lurie N . MMWR Morb Mortal Wkly Rep 2015 64 (35) 972-4 Recent public health emergencies including Hurricane Katrina (2005), the influenza H1N1 pandemic (2009), and the Ebola virus disease outbreak in West Africa (2014-2015) have demonstrated the importance of multiple-level emergency planning and response. An effective response requires integrating coordinated contributions from community-based health care providers, regional health care coalitions, state and local health departments, and federal agency initiatives. This is especially important when planning for the needs of children, who make up 23% of the U.S. population (1) and have unique needs that require unique planning strategies. |
Single newborn screen or routine second screening for primary congenital hypothyroidism
Shapira SK , Hinton CF , Held PK , Jones E , Hannon WH , Ojodu J . Mol Genet Metab 2015 116 (3) 125-32 Routine second screening of most newborns at 8-14days of life for a panel of newborn conditions occurs in 12 U.S. states, while newborns in the other states typically undergo only a single routine newborn screen. The study objective was to evaluate screening consequences for primary congenital hypothyroidism (CH) in one- and two-screen states according to laboratory practices and medical or biochemical characteristics of screen-positive cases. Individual-level medical and biochemical data were retrospectively collected and analyzed for 2251 primary CH cases in one-screen (CA, WI) and two-screen (AL, DE, MD, OR, TX) states. Aggregate data were collected and analyzed for medical and biochemical characteristics of all screened newborns in the states. Among the states evaluated in this study, the detection rate of primary CH was higher in the one-screen states. In the two-screen states, 11.5% of cases were detected on the second screen. In multivariate analyses, only race/ethnicity was a significant predictor of cases identified on the first versus second screen, which likely reflects a physiologic difference in primary CH presentation. Newborn screening programs must heed the potential for newborns with CH not being detected by a single screen, particularly newborns of certain races/ethnicities. If the two-screen states converted to a single screen using their current algorithms, newborns currently identified on the routine second screen would presumably not be detected, resulting in probable delayed diagnosis and treatment. However, based on the one-screen state experiences, with appropriate modifications in screening method and algorithm, the two-screen states might convert to single screen operation for CH without loss in performance. |
Congenital adrenal hyperplasia cases identified by newborn screening in one- and two-screen states.
Held PK , Shapira SK , Hinton CF , Jones E , Hannon WH , Ojodu J . Mol Genet Metab 2015 116 (3) 133-8 There is no clear consensus among state newborn screening programs on whether routine second screening of newborns identifies clinically relevant cases of congenital adrenal hyperplasia. This retrospective study evaluated laboratory practices, along with biochemical and medical characteristics of congenital adrenal hyperplasia (CAH) cases (1) detected on the first newborn screen in one-screen compared to two-screen states, and (2) detected on the first versus the second screen in the two-screen states, to determine the effectiveness of a second screen. A total of 374 confirmed cases of CAH from 2 one-screen states and 5 two-screen states were included in this study. Demographic data and diagnostic information on each reported case were collected and analyzed. Additionally, laboratory data, including screening methodologies and algorithms, were evaluated. The one-screen states reported 99 cases of CAH out of 1,740,586 (1 in 17,500) newborns screened: 88 (89%) identified on the first screen and 5 (5%) identified on the targeted second screen. The two-screen states reported 275 cases of CAH out of 2,629,627 (1 in 9500) newborns screened: 165 (60%) identified on the first screen and 99 (36%) identified on the second screen. Using a multivariate model, the only significant predictor of whether a case was identified on the first or the second screen in the two-screen states was the type of CAH. Compared with classical salt-wasting CAH, classical simple virilizing and non-classical CAH cases were less likely to be detected on the first versus the second screen. The routine second newborn screen is important for identifying children with CAH, particularly simple virilizing and non-classical forms, which might otherwise not be captured through a single screen. |
State legislation, regulations, and hospital guidelines for newborn screening for critical congenital heart defects - United States, 2011-2014
Glidewell J , Olney RS , Hinton C , Pawelski J , Sontag M , Wood T , Kucik JE , Daskalov R , Hudson J . MMWR Morb Mortal Wkly Rep 2015 64 (23) 625-630 Critical congenital heart defects (CCHD) occur in approximately two of every 1,000 live births. Newborn screening provides an opportunity for reducing infant morbidity and mortality. In September 2011, the U.S. Department of Health and Human Services (HHS) Secretary endorsed the recommendation that critical congenital heart defects be added to the Recommended Uniform Screening Panel (RUSP) for all newborns. In 2014, CDC collaborated with the American Academy of Pediatrics (AAP) Division of State Government Affairs and the Newborn Screening Technical Assistance and Evaluation Program (NewSTEPs) to assess states' actions for adopting newborn screening for CCHD. Forty-three states have taken action toward newborn screening for CCHD through legislation, regulations, or hospital guidelines. Among those 43, 32 (74%) are collecting or planning to collect CCHD screening data; however, the type of data collected by CCHD newborn screening programs varies by state. State mandates for newborn screening for CCHD will likely increase the number of newborns screened, allowing for the possibility of early identification and prevention of morbidity and mortality. Data collection at the state level is important for surveillance, monitoring of outcomes, and evaluation of state CCHD newborn screening programs. |
A public health economic assessment of hospitals' cost to screen newborns for critical congenital heart disease
Peterson C , Grosse SD , Glidewell J , Garg LF , Van Naarden Braun K , Knapp MM , Beres LM , Hinton CF , Olney RS , Cassell CH . Public Health Rep 2014 129 (1) 86-93 OBJECTIVE: Critical congenital heart disease (CCHD) was recently added to the U.S. Recommended Uniform Screening Panel for newborns. This evaluation aimed to estimate screening time and hospital cost per newborn screened for CCHD using pulse oximetry as part of a public health economic assessment of CCHD screening. METHODS: A cost survey and time and motion study were conducted in well-newborn and special/intensive care nurseries in a random sample of seven birthing hospitals in New Jersey, where the state legislature mandated CCHD screening in 2011. The sample was stratified by hospital facility level, hospital birth census, and geographic location. At the time of the evaluation, all hospitals had conducted CCHD screening for at least four months. RESULTS: Mean screening time per newborn was 9.1 (standard deviation = 3.4) minutes. Hospitals' total mean estimated cost per newborn screened was $14.19 (in 2011 U.S. dollars), consisting of $7.36 in labor costs and $6.83 in equipment and supply costs. CONCLUSIONS: This federal agency-state health department collaborative assessment is the first state-level analysis of time and hospital costs for CCHD screening using pulse oximetry conducted in the U.S. Hospitals' cost per newborn screened for CCHD with pulse oximetry is comparable with cost estimates of existing newborn screening tests. Hospitals' equipment costs varied substantially based on the pulse oximetry technology employed, with lower costs among hospitals that used reusable screening sensors. In combination with estimates of screening accuracy, effectiveness, and avoided costs, information from this evaluation suggests that CCHD screening is cost-effective. |
Developing a public health-tracking system for follow-up of newborn screening metabolic conditions: a four-state pilot project structure and initial findings.
Hinton CF , Mai CT , Nabukera SK , Botto LD , Feuchtbaum L , Romitti PA , Wang Y , Piper KN , Olney RS . Genet Med 2013 16 (6) 484-90 PURPOSE: The aim of this study was to describe the methods, cases, and initial results of a pilot project using existing public health data collection programs (birth defect surveillance or newborn screening) to conduct long-term follow-up of children with metabolic disorders. METHODS: California, Iowa, New York, and Utah expanded birth defect surveillance or newborn screening programs to collect long-term follow-up data on 19 metabolic disorders. Data elements to monitor health status and services delivered were identified, and record abstraction and data linkages were conducted. Children were followed up through to the age of 3 years. RESULTS: A total of 261 metabolic cases were diagnosed in 1,343,696 live births (19.4 cases/100,000; 95% confidence interval = 17.1-21.8). Four deaths were identified. Children with fatty acid oxidation disorders had a higher percentage of health service encounters compared with children with other disorders of at least one health service encounter (hospitalization, emergency room, metabolic clinic, genetic service provider, or social worker) except for hospitalizations; children with organic acid disorders had a higher percentage of at least one hospitalization during their third year of life than children with other disorders. CONCLUSION: Existing public health data programs can be leveraged to conduct population-based newborn screening long-term follow-up. This approach is flexible according to state needs and resources. These data will enable the states in assessing health burden, assuring access to services, and supporting policy development. |
Improving newborn screening follow-up in pediatric practices: quality improvement innovation network.
Hinton CF , Neuspiel DR , Gubernick RS , Geleske T , Healy J , Kemper AR , Lloyd-Puryear MA , Saul RA , Thompson BH , Kaye CI . Pediatrics 2012 130 (3) e669-75 OBJECTIVE: To implement a 6-month quality improvement project in 15 primary care pediatric practices to improve short-term newborn screening (NBS) follow-up. METHODS: At the start of the project, each practice completed a survey to evaluate office systems related to NBS and completed a chart audit. Practice teams were provided information about NBS and trained in quality-improvement methods, and then implemented changes to improve care. Monthly chart audits over a 6-month period were completed to assess change. RESULTS: At baseline, almost half of practices completed assessment of infants for NBS; after 6 months, 80% of practices completed assessment of all infants. Only 2 practices documented all in-range results and shared them with parents at baseline; by completion, 10 of 15 practices documented and shared in-range results for ≥70% of infants. Use of the American College of Medical Genetics ACTion sheets, a decision support tool, increased from 1 of 15 practices at baseline to 7 of 15 at completion. CONCLUSIONS: Practices were successful in improving NBS processes, including assessment, documentation, and communication with families. Providers perceived no increase in provider time at first visit, 2- to 4-week visit, or during first contact with the family of an infant with an out-of-range result after implementation of improved processes. Primary care practices increased their use of decision support tools after the project. |
What questions should newborn screening long-term follow-up be able to answer? A statement of the US Secretary for Health and Human Services' Advisory Committee on Heritable Disorders in Newborns and Children.
Hinton CF , Feuchtbaum L , Kus CA , Kemper AR , Berry SA , Levy-Fisch J , Luedtke J , Kaye C , Boyle CA . Genet Med 2011 13 (10) 861-865 The US Secretary of Health and Human Services' Advisory Committee on Heritable Disorders in Newborns and Children provides guidance on reducing the morbidity and mortality associated with heritable disorders detectable through newborn screening. Efforts to systematically evaluate health outcomes, beyond long-term survival, with a few exceptions, are just beginning. To facilitate these nascent efforts, the US Secretary of Health and Human Services' Advisory Committee on Heritable Disorders in Newborns and Children initiated a project to define the major overarching questions to be answered to assure that newborn screening is meeting its goal of achieving the best quality outcome for the affected children and their families. The questions identified follow the central components of long-term follow-up-care coordination, evidence-based treatment, continuous quality improvement, and new knowledge discovery-and are framed from the perspectives of the state and nation, primary and specialty healthcare providers, and the impacted families. These overarching questions should be used to guide the development of long-term follow-up data systems, quality health indicators, and specific data elements for evaluating the newborn screening system. |
