Civic engagement, including voting, has been linked to health outcomes for adults. Here, we found that census tract-level voter participation rates are significantly associated with pediatric inpatient bed-day rates even after adjustment for socioeconomic deprivation. Such links suggest that promotion of voting participation could be warranted in healthcare settings.

OBJECTIVE: To develop a diagnostic error index (DEI) aimed at providing a practical method to identify and measure serious diagnostic errors. STUDY DESIGN: A quality improvement (QI) study at a quaternary pediatric medical center. Five well-defined domains identified cases of potential diagnostic errors. Identified cases underwent an adjudication process by a multidisciplinary QI team to determine if a diagnostic error occurred. Confirmed diagnostic errors were then aggregated on the DEI. The primary outcome measure was the number of monthly diagnostic errors. RESULTS: From January 2017 through June 2019, 105 cases of diagnostic error were identified. Morbidity and mortality conferences, institutional root cause analyses, and an abdominal pain trigger tool were the most frequent domains for detecting diagnostic errors. Appendicitis, fractures, and nonaccidental trauma were the 3 most common diagnoses that were missed or had delayed identification. CONCLUSIONS: A QI initiative successfully created a pragmatic approach to identify and measure diagnostic errors by utilizing a DEI. The DEI established a framework to help guide future initiatives to reduce diagnostic errors.

Background: Disparities in health care access for Latinos are well documented, but little is known about how they may impact immigrants from diverse countries of origin differently. Immigrants in nontraditional destination areas face greater disparities, allowing more robust comparison of Latino heritage groups in such regions. Method: Mexican (N = 258) and Guatemalan (N = 143) participants were recruited for a community-based participatory research (CBPR) initiative in Cincinnati, Ohio: Latinos Unidos por la Salud (LU-Salud). Community partners recruited Latino immigrants to complete a brief survey about health care difficulties. Mixed methods data analysis was employed using t tests, Fisher's exact test, and a qualitative content analysis approach to analyze group differences. Results: Although both groups reported challenges, Guatemalans reported greater difficulty navigating health care. Conversely, Mexicans more commonly used local resources like health fairs to seek health information and described fewer language barriers. Qualitatively, Guatemalans and Mexicans had different perceptions of the biggest health problem for Latinos in Cincinnati. Notably, Mexicans identified major chronic diseases as community health problems. Discussion: Mexicans and Guatemalans show different patterns of health care engagement and express distinct concerns. Future work should consider the role of health literacy in informing the heterogenous experiences and needs of Latinos from diverse countries of origin. Further, interventions should train health care providers to provide culturally sensitive services, with interpreters available in multiple languages to address heterogenous language needs.

OBJECTIVE: To describe the demographic and clinical characteristics of a cohort of patients referred to pediatric hospice and home-based palliative care (HBPC) programs across Ohio in 2016. STUDY DESIGN: Retrospective cohort study of patients referred to hospice/HBPC from 3 pediatric palliative care programs in Ohio in 2016. Demographic and clinical data were extracted from the medical record and analyzed with descriptive statistics. RESULTS: There were 209 patients referred: 49 (24%) to hospice and 160 (77%) to HBPC. The most common diagnoses were genetic/chromosomal syndromes (23%), neurologic or neurodegenerative conditions (23%), and cancer (21%). Durable medical equipment use was frequent (85%), with gastrostomy or jejunostomy tubes (22%) the most common. Most patients (64%) retained full-code resuscitation status. Fifty-seven patients (27%) died before July 1, 2018: 37 in hospice (18% of the overall cohort, 65% of decedents) and 20 in HBPC (10% of the overall cohort, 35% of decedents). Sixty-seven percent of hospice and 40% of HBPC patients died at home. CONCLUSIONS: Pediatric hospice and HBPC programs serve a diverse cohort of patients. Patients referred to pediatric HBPC programs commonly die and are likely to die at home despite not being enrolled in hospice care. The high proportion of decedent HBPC patients indicates that the notion of hospice vs palliative care may present a false dichotomy in many children with life-limiting conditions. Reimbursement models for HBPC should reflect the clinical similarity to hospice in the care of children with life-limiting illnesses.

African-American women have disproportionate rates of hypertension that can be further complicated as they transition through menopause. Stress, coupled with depression and hypertension in perimenopausal African-American women has not been fully explored. This study examines the associations of stress, depression, and social support on systolic blood pressure (SBP) among a sample of 184 perimenopausal African-American women. We used descriptive statistics, Pearson's correlation, and logistic regression to analyze data stratified by menopausal status (perimenopausal or menopausal) and SBP status (<130 mmHg vs. >130 mmHg). Women classified as menopausal reported higher levels of stress and depressive symptoms, and lower levels of social support. Age, body mass index (BMI), health insurance, and perceived health status were significant predictors of SBP in menopausal women. Stress, depression, and social support did not play a role in SBP. It is necessary that future research focus on reducing cardiovascular risk include addressing menopausal health.

OBJECTIVES: To estimate the proportion of opioid misuse attributable to adverse childhood experiences (ACEs) among adolescents. STUDY DESIGN: A cross-sectional survey was administered to 10 546 seventh-to twelfth-grade students in northeastern Ohio in Spring 2018. Study measures included self-reported lifetime exposure to 10 ACEs and past 30-day use of nonmedical prescription opioid or heroin. Using generalized estimating equations, we evaluated associations between recent opioid misuse, individual ACEs, and cumulative number of ACEs. We calculated population attributable fractions to determine the proportion of adolescents' recent opioid misuse attributable to ACEs. RESULTS: Nearly 1 in 50 adolescents reported opioid misuse within 30 days (1.9%); approximately 60% of youth experienced ≥1 ACE; 10.2% experienced ≥5 ACEs. Cumulative ACE exposure demonstrated a significant graded relationship with opioid misuse. Compared with youth with zero ACEs, youth with 1 ACE (aOR 1.9, 95% CI, 0.9-3.9), 2 ACEs (aOR, 3.8; 95% CI, 1.9-7.9), 3 ACEs (aOR, 3.7; 95% CI, 2.2-6.5), 4 ACEs (aOR, 5.8; 95% CI, 3.1-11.2), and ≥5 ACEs (aOR, 15.3; 95% CI, 8.8-26.6) had higher odds of recent opioid misuse. The population attributable fraction of recent opioid misuse associated with experiencing ≥1 ACE was 71.6% (95% CI, 59.8-83.5). CONCLUSIONS: There was a significant graded relationship between number of ACEs and recent opioid misuse among adolescents. More than 70% of recent adolescent opioid misuse in our study population was attributable to ACEs. Efforts to decrease opioid misuse could include programmatic, policy, and clinical practice interventions to prevent and mitigate the negative effects of ACEs.

OBJECTIVE: To investigate whether exposure to tobacco smoke during early brain development is linked with later problems in behavior and executive function. STUDY DESIGN: We studied 239 children in a prospective birth cohort. We measured tobacco exposures by caregiver report and serum cotinine 3 times during pregnancy and 4 times during childhood. We used linear regression to examine the association between prenatal and childhood serum cotinine concentrations and behavior (the Behavior Assessment System for Children-2) and executive function (the Behavior Rating Inventory of Executive Function) at age 8 years while adjusting for important covariates. RESULTS: Neither prenatal nor child serum cotinine were associated with behavior problems measured by the Behavior Assessment System for Children-2. On the Behavior Rating Inventory of Executive Function, prenatal and childhood exposure was associated with poorer task initiation scores (B = 0.44; 95% CI, 0.03-0.85 and B = 0.69, 95% CI, 0.06-1.32 respectively). Additionally, in a subset of 208 children with nonsmoking mothers, prenatal exposure was associated with task initiation scores (B = 1.17; 95% CI, 0.47-1.87) and additional components of the metacognition index (eg, working memory, B = 1.20; 95% CI, 0.34-2.06), but not components of the behavioral regulation index. CONCLUSIONS: Tobacco exposures during pregnancy (including low-level second-hand smoke) and childhood were associated with deficits in some domains of children's executive function, especially task initiation and metacognition. These results highlight that decreasing early exposure to tobacco smoke, even second-hand exposure, may support ideal brain functioning.

OBJECTIVE: To identify factors associated with neurodevelopmental impairment (NDI) in patients with bronchopulmonary dysplasia (BPD). STUDY DESIGN: We identified 151 patients with moderate to severe BPD from 2010 to 2014 with complete Bayley Scales of Infant Development (BSID) scores at 24 months corrected age. We defined NDI as any diagnosis of cerebral palsy or ≥1 BSID composite scores of <80. RESULTS: The mean corrected age at BSID was 23 ± 1 months; 18% had a cognitive score of <80, 37% had a communication score of <80, and 26% had a motor score of <80. Cerebral palsy was diagnosed in 22 patients (15%); 84 (56%) patients did not have NDI. Patients with NDI had lower birth weight, but there was no difference in gestational age at birth, severe intraventricular hemorrhage (IVH), necrotizing enterocolitis, or patent ductus arteriosus ligation compared with patients with no NDI. Ventilator days were greater in patients with NDI than in patients without NDI. More patients with NDI received furosemide and systemic corticosteroids and the hospital length of stay was longer than in patients with no NDI. Logistic regression modeling demonstrated that for every additional 100 g of birth weight the odds of NDI decreased by 35% and for every additional hospital day the odds of NDI increased by 1.3%. CONCLUSIONS: In our cohort of patients with moderate to severe BPD, the majority had no NDI, and low birth weight and length of hospital stay were associated with increased risk of developing NDI. This finding suggests that there are potentially modifiable factors associated with better neurodevelopmental outcomes in patients with BPD that deserve further study.

Heterodera glycines, the soybean cyst nematode, and Macrophomina phaseolina, causal agent of charcoal rot, are economically important soybean pathogens. The impact and effect of these pathogens on soybean yield in coinfested fields in the Midwest production region is not known. Both pathogens are soilborne, with spatially aggregated distribution and effects. Spatial regression analysis, therefore, is an appropriate method to account for the spatial dependency in either the dependent variable or regression error term from data produced in fields naturally infested with H. glycines and M. phaseolina. The objectives of this study were twofold: to evaluate the combined effect of H. glycines and M. phaseolina on soybean yield in naturally infested commercial fields with ordinary least squares and spatial regression models; and to evaluate, under environmentally controlled conditions, the combined effect of H. glycines and M. phaseolina through nematode reproduction and plant tissue fungal colonization. Six trials were conducted in fields naturally infested with H. glycines and M. phaseolina in Ohio. Systematic-grid sampling was used to determine the population densities of H. glycines and M. phaseolina, and soybean yield estimates. Though not used in any statistical analysis, M. phaseolina colony forming units from plant tissue, charcoal rot severity, and H. glycines type were also recorded and summarized. In two greenhouse experiments, treatments consisted of H. glycines alone, M. phaseolina alone, and coinfestation of soybean with both pathogens. Moran's I test indicated that the yield from five fields was spatially correlated (P < 0.05) and aggregated. In these fields, to account for spatial dependence, spatial regression models were fitted to the data. Spatial regression analyses revealed a significant interaction effect between H. glycines and M. phaseolina on soybean yield for fields with high initial population densities of both pathogens. In the greenhouse experiments, H. glycines reproduction was significantly (P < 0.05) reduced in the presence of M. phaseolina; however, soybean tissue fungal colonization was not affected by the presence of H. glycines. The direct mechanisms by which H. glycines and M. phaseolina interact were not demonstrated in this study. Future studies must be conducted in the field and greenhouse to better understand this interaction effect.

Blattophila peregrinata Carreno, 2017 (Nematoda: Oxyuridomorpha: Thelastomatidae) is proposed as a junior synonym of Suifunema peregrinatum (Carreno, 2017) n. comb., based on the revision of the type material of S. caudelli Chitwood, 1932, the type and only species of the genus. The revision permitted the emendation of some features of the original descriptions, namely the position of the nerve ring at level of the corpus instead the isthmus and the female genital tract didelphic-prodelphic instead didelphic-amphidelphic. The males of S. peregrinatum n. comb. are the only ones known for the genus. Thus, an amended generic diagnosis is given, including information on the males. Both S. peregrinatum n. comb. and S. caudelli differ by having a more slender body, a longer tail, and the vulva farther from the anterior end in the former. S. peregrinatum n. comb. is recorded for the first time from Pycnoscelus indicus Fabricius, 1775 (Blattodea: Blaberidae) from Japan. The specimens from Japan are morphologically consistent with other populations of the species from the USA and the Galapagos Islands of Ecuador. Only some morphometrics vary slightly, but these are within the range of the species. The phylogenetic position of the genus among the family Thelastomatidae is discussed, including sequences of the D2-D3 LSU rDNA of specimens from both the type population (Ohio, USA) and Japan.

The females of Xyo pseudohystrix Travassos Kloss, 1958 (Nematoda: Oxyuridomorpha: Hystrignathidae) are redescribed and illustrated with the aid of SEM. New features of the cephalic end, arrangement of the cervical spines and genital tract were observed. The taxonomic status of the species is discussed on the basis of discrepancies with the generic diagnosis of Xyo Cobb, 1898. Due to the lack of proper information on the genus the status of incertae sedis is proposed. The identity of the males was confirmed by molecular studies and the morphology of the specimens previously assigned by Christie (1932) as males of Hystrignathus rigidus Leidy, 1858 correspond to the current species. New locality records are given for the states of Georgia and Ohio, USA. The phylogenetic position of the species is inferred on the basis of the D2-D3 segment of the LSU rDNA and SSU rDNA.

Polymorphus trochus Van Cleave, 1945, is an acanthocephalan with limited distribution to the Americas and a common parasite of birds of the Rallidae family (Kinsella et al. 1973, McDonald 1988 and Amin 1992), mainly of the American coot Fulica americana Gmelin, 1789; however, despite existing records of this species, the knowledge and descriptions of its morphological characteristics are not sufficient. Therefore, the identification of this species can be confusing, particularly because it depends on the form of the proboscis of the female. Van Cleave (1945) provided a description and illustrations of this species based on 14 females and 2 males specimens collected in the intestine of F. americana from Lake Buckeye in Ohio, Lake Oneida in New York, and the Illinois River in Illinois; however, this description does not mention many traits that are taxonomically important. Years later, Nickol (1966, thesis not published) provided a description of P. trochus based on 36 mature specimens (14 females and 22 male) from Louisiana, but the author illustrated only the proboscis and included a schematic of the female. He described the shape and size of the proboscis in both sexes, provided measurements of the apical, middle and basal hooks of the proboscis armor, and measurements of the eggs. However, he did not mention the exact distribution of the hooks and spines of the trunk, the measurement of a complete row of hooks nor the shape of all the sexual organs, especially the female ones, which are important taxonomic characteristics in the polymorphids.

OBJECTIVES: To examine patient- and provider-level factors associated with receiving attention-deficit/hyperactivity disorder (ADHD) medication treatment in a community care setting. We hypothesized that the likelihood of ADHD medication receipt would be lower in groups with specific patient sociodemographic (eg, female sex, race other than white) and clinical (eg, comorbid conditions) characteristics as well as physician characteristics (eg, older age, more years since completing training). STUDY DESIGN: A retrospective cohort study was conducted with 577 children (mean age, 7.8 years; 70% male) presenting for ADHD to 50 community-based practices. The bivariate relationship between each patient- and physician-level predictor and whether the child was prescribed ADHD medication was assessed. A multivariable model predicting ADHD medication prescription was conducted using predictors with significant (P < .05) bivariate associations. RESULTS: Sixty-nine percent of children were prescribed ADHD medication in the year after initial presentation for ADHD-related concerns. Eleven of 31 predictors demonstrated a significant (P < .05) bivariate relationship with medication prescription. In the multivariable model, being male (OR, 1.34; 95% CI, 1.01-1.78; P = .02), living in a neighborhood with higher medical expenditures (OR, 1.11 for every $100 increase; 95% CI, 1.03-1.21; P = .005), and higher scores on parent inattention ratings (OR, 1.06; 95% CI, 1.03-1.10; P < .0001) increased the likelihood of ADHD medication prescription. CONCLUSIONS: We found that some children, based on sociodemographic and clinical characteristics, are less likely to receive an ADHD medication prescription. An important next step will be to examine the source and reasons for these disparities in an effort to develop strategies for minimizing treatment barriers.

BACKGROUND: Aspirin is established as an effective prophylaxis for venous thromboembolism (VTE) after THA; however, there is no consensus as to whether low- or regular-dose aspirin is more effective at preventing VTE. QUESTIONS/PURPOSES: (1) Is there a difference in the incidence of symptomatic VTE within 90 days of elective THA using low-dose aspirin compared with regular-dose aspirin? (2) Is there a difference in the risk of significant bleeding (gastrointestinal and wound bleeding) and mortality between low- and standard-dose aspirin within 90 days after surgery? METHODS: We retrospectively evaluated 7488 patients in our database who underwent THA between September 2012 and December 2016. A total of 3936 (53%) patients received aspirin alone for VTE prophylaxis after THA. During the study period, aspirin was prescribed as a monotherapy for VTE prophylaxis after surgery in low-risk patients (no history of VTE, recent orthopaedic surgery, hypercoagulable state, history of cardiac arrhythmia requiring anticoagulation, or receiving anticoagulation for any other medical conditions before surgery). Patients were excluded if aspirin use was contraindicated because of peptic ulcer disease, intolerance, or other reasons. Patients received aspirin twice daily (BID) for 4 to 6 weeks after surgery and were grouped into two cohorts: a low-dose (81 mg BID) aspirin group (n = 1033) and a standard-dose (325 mg BID) aspirin group (n = 2903). The primary endpoint was symptomatic VTE (deep vein thrombosis [DVT] and pulmonary embolism [PE]). Secondary endpoints included significant bleeding (gastrointestinal [GI] and wound) and mortality. Exploratory univariate analyses were used to compare confounders between the study groups. Multivariate regression was used to control for confounding variables (including age, sex, body mass index, comorbidities, and surgeon) as we compared the study groups with respect to the proportion of patients who developed symptomatic VTE, bleeding (GI or wound), and mortality within 90 days of surgery. RESULTS: The 90-day incidence of symptomatic VTE was 1.0% in the 325-mg group and 0.6% in the 81-mg group (p = 0.35). Symptomatic DVT incidence was 0.8% in the 325-mg group and 0.5% in the 81-mg group (p = 0.49), and the incidence of symptomatic PE was 0.3% in the 325-mg group and 0.2% in the 81-mg group (p = 0.45). Furthermore, bleeding was observed in 0.8% of the 325-mg group and 0.5% of the 81-mg group (p = 0.75), and 90-day mortality was not different (0.1%) between the groups (p = 0.75). After accounting for confounders, regression analyses showed no difference between aspirin doses and the 90-day incidence of symptomatic VTE (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.29-2.85; p = 0.85) or symptomatic DVT (OR, 0.96; 95% CI, 0.26-3.59; p = 0.95). CONCLUSIONS: We found no difference in the incidence of symptomatic VTE after THA with low-dose compared with standard-dose aspirin. In the absence of compelling evidence to the contrary, low-dose aspirin appears to be a reasonable option for VTE prophylaxis in otherwise healthy patients undergoing elective THA. LEVEL OF EVIDENCE: Level III, therapeutic study.
