Outbreaks of Acute Gastrointestinal Illness Associated with a Splash Pad in a Wildlife Park - Kansas, June 2021.

In June 2021, Kansas state and county public health officials identified and investigated three cases of shigellosis (a bacterial diarrheal illness caused by Shigella spp.) associated with visiting a wildlife park. The park has animal exhibits and a splash pad. Two affected persons visited animal exhibits, and all three entered the splash pad. Nonhuman primates are the only known animal reservoir of Shigella. The splash pad, which sprays water on users and is designed so that water does not collect in the user area, was closed on June 19. The state and county public health codes do not include regulations for splash pads. Thus, these venues are not typically inspected, and environmental health expertise is limited. A case-control study identified two distinct outbreaks associated with the park (a shigellosis outbreak involving 21 cases and a subsequent norovirus infection outbreak involving six cases). Shigella and norovirus can be transmitted by contaminated water; in both outbreaks, illness was associated with getting splash pad water in the mouth (multiply imputed adjusted odds ratio [aORMI] = 6.4, p = 0.036; and 28.6, p = 0.006, respectively). Maintaining adequate water disinfection and environmental health expertise and targeting prevention efforts to caregivers of splash pad users help prevent splash pad-associated outbreaks. Outbreak incidence might be further reduced when U.S. jurisdicitons voluntarily adopt CDC's Model Aquatic Health Code (MAHC) recommendations and through the prevention messages: "Don't get in the water if sick with diarrhea," "Don't stand or sit above the jets," and "Don't swallow the water."†.

Assessing the Effectiveness of a School-Based Dental Clinic on the Oral Health of Children Who Lack Access to Dental Care.

This program evaluation examines the effectiveness of a school-based dental clinic. A repeated-measures design was used to longitudinally examine secondary data from participants ( N = 293). Encounter intensity was developed to normalize data. Multivariate analysis of variance and Kruskal-Wallis test were used to investigate the effect of encounter intensity on the change in decay, restorations, and treatment urgency. A Pearson's correlation was used to measure the strengths of association. Encounter intensity had a statistically significant effect on change in decay ( p = .005), restorations ( p = .000), and treatment urgency ( p = .001). As encounter intensity increased, there was a significant association with the decrease in decay (-.167), increase in restorations (.221), and reduction in referral urgency (-.188). Incorporating dental care into a school-based health center resulted in improved oral health in underserved children while overcoming barriers that typically restrict access. The collaboration of school nurses with the school-based dental clinic was an important element for maximizing student access to dental care.

Polyoxyethylene Tallow Amine, a Glyphosate Formulation Adjuvant: Soil Adsorption Characteristics, Degradation Profile, and Occurrence on Selected Soils from Agricultural Fields in Iowa, Illinois, Indiana, Kansas, Mississippi, and Missouri.

Polyoxyethylene tallow amine (POEA) is an inert ingredient added to formulations of glyphosate, the most widely applied agricultural herbicide. POEA has been shown to have toxic effects to some aquatic organisms making the potential transport of POEA from the application site into the environment an important concern. This study characterized the adsorption of POEA to soils and assessed its occurrence and homologue distribution in agricultural soils from six states. Adsorption experiments of POEA to selected soils showed that POEA adsorbed much stronger than glyphosate; calcium chloride increased the binding of POEA; and the binding of POEA was stronger in low pH conditions. POEA was detected on a soil sample from an agricultural field near Lawrence, Kansas, but with a loss of homologues that contain alkenes. POEA was also detected on soil samples collected between February and early March from corn and soybean fields from ten different sites in five other states (Iowa, Illinois, Indiana, Missouri, Mississippi). This is the first study to characterize the adsorption of POEA to soil, the potential widespread occurrence of POEA on agricultural soils, and the persistence of the POEA homologues on agricultural soils into the following growing season.

Effectiveness of an Alternative Dental Workforce Model on the Oral Health of Low-Income Children in a School-Based Setting.

OBJECTIVES: We evaluated the effect of an alternative dental workforce program-Kansas's Extended Care Permit (ECP) program--as a function of changes in oral health. METHODS: We examined data from the 2008 to 2012 electronic medical records of children (n = 295) in a Midwestern US suburb who participated in a school-based oral health program in which preventive oral health care was delivered by ECP dental hygienists. We examined changes in oral health status as a function of sealants, caries, restorations, and treatment urgency with descriptive statistics, multivariate analysis of variance, Kruskal-Wallis test, and Pearson correlations. RESULTS: The number of encounters with the ECP dental hygienist had a statistically significant effect on changes in decay (P = .014), restorations (P = .002), and treatment urgency (P = .038). Based on Pearson correlations, as encounters increased, there was a significant decrease in decay (-0.12), increase in restorations (0.21), and decrease in treatment urgency (-0.15). CONCLUSIONS: Increasing numbers of encounters with alternative providers (ECP dental hygienists), such as with school-based oral health programs, can improve the oral health status of low-income children who would not otherwise have received oral health services.

Community-Led Interventions to Address Food Inequity.

Approximately 1 in 6 children in the United States, and 1 in 5 children in our local county (Hamilton County, Ohio), are food insecure. Here, we describe a novel community-academic partnership to address food inequity through distributed leadership and shared power with local neighborhood leaders. Using neighborhood-level data and community voice, 3 Cincinnati neighborhoods with high rates of poverty and food insecurity were selected as the primary intervention targets. Neighborhood leadership councils with community members representing each neighborhood were created. These councils requested intervention proposals and then decided which community designed interventions would receive grant funding. The academic partner provided grant funding distribution, quality improvement support, and data guidance and support for all partners, as well as community engagement support if desired by the community-led intervention leaders. In its first year (2021-2022), 9 interventions were funded, moving more than $250 000 into community-designed and community-led interventions to promote food security in 3 disadvantaged neighborhoods. Through leveraging community partnerships, these initiatives supplied 89 039 equivalent meals, including 56 244 pounds of produce, serving at least 3106 families in 3 neighborhoods in Cincinnati. Critical to the success of the initiatives were distributed leadership, shared power, word of mouth, and community engagement. The success of this type of community-academic partnership shows promise to address a wide variety of social and health challenges.

Vancomycin-resistant gram-positive cocci isolated from the saliva of wild songbirds.

We analyzed highly vancomycin-resistant Gram-positive bacteria isolated from the saliva of migratory songbirds captured, sampled, and released from a bird-banding station in western Kansas. Individual bacterial isolates were identified by partial 16S rRNA sequencing. Most of the bacteria in this study were shown to be Staphylococcus succinus with the majority being isolated from the American Robin. Some of these bacteria were shown to carry vanA, vanB, and vanC vancomycin-resistance genes and have the ability to form biofilms. One of the van gene-carrying isolates is also coagulase positive, which is normally considered a virulence factor. Other organisms isolated included Staphylococcus saprophyticus as well as Enterococcus gallinarum. Given the wide range of the American Robin and ease of horizontal gene transfer between Gram-positive cocci, we postulate that these organisms could serve as a reservoir of vancomycin-resistance genes capable of transferring to human pathogens.

Prevalence and risk factors of dental erosion in American children.

OBJECTIVES: The purpose of this study was to assess the prevalence and characteristics of dental erosion in children aged 2-4 years old and 12 years old. STUDY DESIGN: 243 subjects were recruited from daycare centers, preschools, and grade schools; they received dental examinations assessing their condition of dental erosion, including both depth and area of tooth surface loss on four maxillary incisors. Questionnaires were given to the subjects to obtain socio-demographic, oral health behaviors at home, and access to dental care. Dental erosion was analyzed and risk factors were assessed using Chi-Square and logistic regression analysis. RESULTS: The subjects were 60% Caucasians, 31% Black, 7% Hispanic and others were 2%. 34% of children could not get the dental care they needed within the past 12 months and 61% of all children brushed their teeth twice or more daily. Overall, 12% of study children had dental erosion with 13% for 2-4 years old and 10% for 12 years old, with the majority of erosive lesions within enamel. Family income (OR 3.98, p = 0.021) and acidic fruit juice consumption (OR 2.38, p = 0.038) were significant risk factors for dental erosion, even after controlling for other factors, such as source of drinking water and oral hygiene using logistic regression analysis. CONCLUSIONS: Dental erosion is a relatively common problem among the children in this study and it is seen as a multi-factorial process.

Kansas Extended Care Permit III Providers: A descriptive study.

Purpose Forty-two states to date have passed legislation to expanded the role of dental hygienists for improved access to basic oral health services for underserved populations. Recent legislative changes in the state of Kansas have created the Extended Care Permit (ECP) I, II, and III designations. The purpose of this study was to examine the experiences of registered dental hygienists in Kansas holding ECP III certificates.Methods Secondary data analysis was performed utilizing data collected from an ECP provider survey conducted in 2021. Dental hygienists in Kansas holding an Extended Care Permit III (n=88) were sent a 39-item electronic survey and informed consent was obtained prior to beginning the survey. Descriptive data analyses consisted of frequency distributions and percentages. Inferential data analysis consisted of Fisher's Exact and Chi-Square tests to evaluate associations between ECP III demographics, practice characteristics, and services provided.Results A total of 22 responses were received for a 25% response rate. The majority of the respondents (77%) were employed by a Safety Net Clinic. The practice settings reporting the highest percentage of ECP III services during the period of data collection were school-based settings, using portable equipment (68%). No associations were found between ECP III personal and practice characteristics and the provision of services specific to the ECP III permit.Conclusion Results suggest that a low percentage of ECP III permit holders are providing ECP III-specific services. Considering these findings and the outcomes of previous studies, there is speculation that barriers continue to exist that prevent permit holders from performing ECP III-specific services and providing dental hygiene services to the fullest extent of an ECP license.

American Indian/Alaska Native willingness to provide biological samples for research purposes.

This article examines the willingness of American Indian/Alaska Natives (AI/AN) to provide biological samples for research purposes. Prior cases of abuse and misuse of individuals, materials, and data highlight ethical research concerns. Investigators may be hesitant to engage AI/ANs in research projects. We conducted a survey of AI/ANs in the central plains region of the US over 1 year. This convenience sample completed a series of questions on biological samples and research. Survey results (N=998) indicate that 70.15% of AI/ANs would be willing to provide saliva/spit for a specific study with the proper consent and control of samples. In conclusion, researchers should find ways to work with and for AI/ANs, assuring participant input in the research process.

Pax5 and CD3 immunophenotyping of lymphoma in 2 central bearded dragons.

Two central bearded dragons (Pogona vitticeps), a 3-y-old male and a 5-y-old female, were diagnosed with different manifestations of lymphoma at the Kansas State Veterinary Diagnostic Laboratory between 2019 and 2020. The 3-y-old male was presented for postmortem evaluation and was in poor body condition. Microscopically, nearly all examined organs contained variable numbers of neoplastic round cells. Neoplastic cells in the stomach and liver had moderate immunoreactivity to CD3 consistent with multicentric T-cell lymphoma, and non-neoplastic lymphocytes infiltrating the stomach mass had strong immunoreactivity to Pax5. The 5-y-old female had an ulcerated oral mass located in the right lingual gingiva submitted as an excisional biopsy. Microscopically, the mass was composed of large numbers of neoplastic round cells in the epithelium and connective tissue that were strongly and diffusely positive for CD3 and frequently positive for Pax5, consistent with a dual-positive, localized, epitheliotropic T-cell lymphoma. Neoplastic and non-neoplastic lymphocytes did not stain with CD20 or CD79a. Neoplasms are increasingly reported as a cause of morbidity and mortality in reptiles. Our 2 cases illustrate various presentations of T-cell lymphoma and the effectiveness of CD3 and Pax5 immunohistochemistry in bearded dragons.

Simulating human behavioral changes in livestock production systems during an epidemic: The case of the US beef cattle industry.

Human behavioral change around biosecurity in response to increased awareness of disease risks is a critical factor in modeling animal disease dynamics. Here, biosecurity is referred to as implementing control measures to decrease the chance of animal disease spreading. However, social dynamics are largely ignored in traditional livestock disease models. Not accounting for these dynamics may lead to substantial bias in the predicted epidemic trajectory. In this research, an agent-based model is developed by integrating the human decision-making process into epidemiological processes. We simulate human behavioral change on biosecurity practices following an increase in the regional disease incidence. We apply the model to beef cattle production systems in southwest Kansas, United States, to examine the impact of human behavior factors on a hypothetical foot-and-mouth disease outbreak. The simulation results indicate that heterogeneity of individuals regarding risk attitudes significantly affects the epidemic dynamics, and human-behavior factors need to be considered for improved epidemic forecasting. With the same initial biosecurity status, increasing the percentage of risk-averse producers in the total population using a targeted strategy can more effectively reduce the number of infected producer locations and cattle losses compared to a random strategy. In addition, the reduction in epidemic size caused by the shifting of producers' risk attitudes towards risk-aversion is heavily dependent on the initial biosecurity level. A comprehensive investigation of the initial biosecurity status is recommended to inform risk communication strategy design.

Workforce Policies and their Influence on School-Based Oral Health Programs: A synthesis of four case studies.

Purpose: Childhood caries disproportionately effects children who are poor, live in low-income rural and urban areas, and come from racial and ethnic minority groups. The purpose of this study was to explore the effect of public policy related to dental hygienists' level of supervision and policy uptake at the state level on the organization, delivery, and financing of school-based oral health programs (SBOHP).Methods: A multiple case study methodology was used to compare SBOHPs in the states of Missouri and Kansas. Interviews were conducted with an administrator, dental hygienist, and dentist at each Federally Qualified Health Center (FQHC) that operated a SBOHP. Mixed methods were used to conduct and analyze interviews, examine supporting documents, and to report descriptive details. Analytic categories were used to examine the various facets of the organizational structures, delivery processes, financing and billing, and operations.Results: Five themes revealing differences between two states emerged; historical development of SBOHPs, the structure of SBOHPs, staffing and professional relationships, finance and billing, and capacity of school-based oral health network.Conclusion: Dental hygienists' supervision requirements play a critical role in school-aged children's access to oral health services and the capacity of SBOHPs. The variations in the degree of practice autonomy accorded to dental hygienists under the Missouri and Kansas dental practice acts resulted in different oral health delivery models. Greater autonomy for dental hygienists is essential for realizing the promise of dental public health.

Dual institution validation of an ageism scale for dental students.

PURPOSE/AIM: Ageism negatively affects health care. This paper presents an extended validation of a novel scale assessing ageism among dental students. METHOD AND MATERIALS: A previously pilot-tested 27-question scale applied to a larger sample (n = 315) from two U.S. dental schools with Principal Component Analysis used to assess internal structure of the measure. Questions whose deletion increased the overall α loading on >1 factor or those unexpectedly grouped in another factor were thoroughly examined. RESULTS: The scale resulted in five statements (grouped in two factors), which explained 63% of the overall variance with a substantially higher reliability value than other solutions (0.76). Two factors highly correlated were grouped together in a single scale. The five statements are "Elderly people do not take good care of their teeth" (0.62), "Elderly patients do not usually comply with dental advice" (0.93), "The Elderly patient does not live long enough to make it worthwhile to invest time and effort in complex dental treatment" (0.81), "The elderly patient does not live long enough to make it worthwhile to invest money in expensive dental treatment" (0.95), and "Dental treatment of elderly patients is too time-consuming" (0.57). CONCLUSIONS: Five items achieved high reliability toward the validity of this scale.

Medicaid managed care: issues for enrollees with serious mental illness.

OBJECTIVES: To inform state Medicaid programs and managed care organizations, as well as to build their capacity to serve enrollees with complex needs related to serious mental illness (SMI). STUDY DESIGN: Quantitative and qualitative analyses of survey results from a sample of Medicaid enrollees with SMI in Kansas in 2016 and 2017 (N = 189). METHODS: Surveys were conducted by telephone or in person at community mental health centers. Analyses of descriptive statistics from closed-item responses and coded transcripts were used to identify major themes in open-item responses. RESULTS: Respondents reported high rates of comorbid physical and mental health conditions and current or past tobacco use. Most were unemployed, and some were homeless or living in unstable conditions. Participants indicated a need for better information and communication; improved access to prescriptions, dental care, reliable transportation, medical supplies, and equipment; and a wider physician/provider network. They wanted care coordinators to provide more frequent and responsive contact, better information about benefits and resources, and help navigating the system. CONCLUSIONS: Individuals with chronic and complex conditions can be challenging for managed care organizations to support, especially Medicaid enrollees with SMI, who experience high rates of comorbid physical health conditions and complex healthcare needs. To the extent that managed care organizations can help this population navigate their coverage and use more of the available benefits, barriers to care and unmet needs can be reduced or eliminated and outcomes subsequently improved.

David Farrar Mitchell: dental researcher & educator.

David Farrar Mitchell, DDS, PhD (1918-1975), was a pioneer in aviation dentistry and a leader in dental education, service and research. In the mid-1940's, he was the first dental officer assigned to the School of Aviation Medicine (SAM) in San Antonio, Texas, a unique, Army Air Corps organization for research and teaching. From 1942-1946, as a trained dental researcher and oral pathologist, he published works on dental problems afflicting military aviators, especially those associated with high altitude flying. His work greatly influenced ongoing dental treatment of military flyers. He served as faculty chairman of two dental schools: The University of Minnesota (1948-1955) and Indiana University (1955-1975). Of his 33 graduate students in oral pathology/medicine, 28 became department chairs at dental schools throughout the world. He was president of the American Academy of Oral Pathology (1962) and of the American Association for Dental Research (1975). From 1969 to 1975, he was editor of the prestigious Journal of Dental Research. During his professional career, Dr. Mitchell published 120 scientific articles on diverse topics relating to oral diagnosis and oral medicine.

Oral Health Needs and Experiences of Medicaid Enrollees With Serious Mental Illness.

INTRODUCTION: Chronic dental diseases are among the most prevalent chronic conditions in the U.S., despite being largely preventable. Individuals with mental illness experience multiple risk factors for poor oral health and need targeted intervention. This study investigated experiences of Kansas Medicaid enrollees with serious mental illness in accessing dental services, examined their oral health risk factors, and identified oral health needs and outcomes. METHODS: Survey data were collected from October 2016 through February 2017 from 186 individuals in Kansas with serious mental illness enrolled in Medicaid. Data were analyzed quantitatively (descriptive and bivariate statistics) and qualitatively (for major themes). RESULTS: Despite Medicaid coverage of dental cleanings, 60.2% of respondents had not seen a dentist in the last 12 months. Reasons included out-of-pocket costs, lack of perceived need, uncertainty about coverage, difficulty accessing providers, fear of the dentist, and transportation issues. High rates of comorbid physical health conditions, including diabetes and cardiovascular disease, and current or former tobacco use were also observed. CONCLUSIONS: Medicaid dental benefits that cover only dental cleanings and low levels of oral health knowledge create barriers to utilizing needed preventive dental care. Lack of perceived need for preventive dental services and lack of contact with dentists necessitates the development of targeted oral health promotion efforts that speak to the specific needs of this group and are disseminated in locations of frequent contact. The Medicaid population with serious mental illness would be an ideal group to target for the integration of chronic oral, physical, and mental health prevention services and control.

The supply of dentists and access to care in rural Kansas.

CONTEXT: Rural deficits in dental care and oral health are well documented and are typically attributed to the low number of dentists practicing in rural areas, but the relationships between rural residence, dental supply, and access to care have not been firmly established, impeding the development of effective public policy. PURPOSE: The purpose of this study is to develop a conceptual framework for observed variations in dental supply, oral health, and access to dental care in rural versus nonrural areas, and to test key empirical implications of this framework (eg, whether lower levels of utilization are associated with the lack of dentists and/or other aspects of residence in a rural area). METHODS: This study employs descriptive statistics, bivariate analyses, and multiple logistic regression to describe the relationship between oral health, access to care, and the supply of dentists in rural versus nonrural populations. Data analyzed includes Kansas' dental licensure records and the 2002 Behavioral Risk Factor Surveillance System. FINDINGS: Bivariate results confirm that dental supply, access to care, and oral health are lower for populations living in rural areas. Multivariate models indicate that dentist supply has a positive and independent association with utilization, but that rurality is not associated with utilization and oral health after controlling for demographics and dentist supply. CONCLUSIONS: Findings are consistent with a conceptual framework linking the geography of rural residence, individual preferences for services such as dental care, and the financial disincentives for dentists to locate in rural areas.

Experiences of the Kansas Extended Care Permit Providers: A descriptive study.

Purpose: A total of 40 states to date have expanded the role of dental hygienists with the goal of improving access to basic oral health services for underserved populations. In Kansas, legislative changes have resulted in the Extended Care Permit (ECP) designation. The purpose of this study is to describe the experiences of registered dental hygienists in Kansas holding ECP certificates (ECP RDH) as of July of 2014.Methods: Secondary data analysis was performed utilizing data collected from a survey conducted in 2014 by Oral Health Kansas. All registered ECP RDH's were sent the 32-item survey via Survey Monkey®. Descriptive statistical analyses consisted of frequency distributions, and measures of central tendency. Inferential analyses using t-tests and ANOVA were conducted to compare groups.Results: A total of 73 responses were received from the (n= 176) surveys that were e-mailed for a 41% response rate. Of the clinicians who responded, 80%, worked at least part-time and in school settings. The most consistent barriers to providing care were the inability to directly bill insurance (52%), financial sustainability (42%) and physical requirements (42%). Follow-up tests found significant differencs between clinician groups when examining barriers.Conclusion: Although the ECP legislation appears to be expanding access to care for citizens in Kansas, significant barriers still exist in making this a viable model for oral healthcare delivery.

Efficacy of Neoadjuvant Carboplatin plus Docetaxel in Triple-Negative Breast Cancer: Combined Analysis of Two Cohorts.

PURPOSE: Recent studies demonstrate that addition of neoadjuvant (NA) carboplatin to anthracycline/taxane chemotherapy improves pathologic complete response (pCR) in triple-negative breast cancer (TNBC). Effectiveness of anthracycline-free platinum combinations in TNBC is not well known. Here, we report efficacy of NA carboplatin + docetaxel (CbD) in TNBC. EXPERIMENTAL DESIGN: The study population includes 190 patients with stage I-III TNBC treated uniformly on two independent prospective cohorts. All patients were prescribed NA chemotherapy regimen of carboplatin (AUC 6) + docetaxel (75 mg/m2) given every 21 days × 6 cycles. pCR (no evidence of invasive tumor in the breast and axilla) and residual cancer burden (RCB) were evaluated. RESULTS: Among 190 patients, median tumor size was 35 mm, 52% were lymph node positive, and 16% had germline BRCA1/2 mutation. The overall pCR and RCB 0 + 1 rates were 55% and 68%, respectively. pCRs in patients with BRCA-associated and wild-type TNBC were 59% and 56%, respectively (P = 0.83). On multivariable analysis, stage III disease was the only factor associated with a lower likelihood of achieving a pCR. Twenty-one percent and 7% of patients, respectively, experienced at least one grade 3 or 4 adverse event. CONCLUSIONS: The CbD regimen was well tolerated and yielded high pCR rates in both BRCA-associated and wild-type TNBC. These results are comparable with pCR achieved with the addition of carboplatin to anthracycline-taxane chemotherapy. Our study adds to the existing data on the efficacy of platinum agents in TNBC and supports further exploration of the CbD regimen in randomized studies. Clin Cancer Res; 23(3); 649-57. ©2016 AACR.
