Patterns of Hospice and Home-Based Palliative Care in Children: An Ohio Pediatric Palliative Care and End-of Life Network Study.

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.

Association of Psychosocial Symptoms, Blood Pressure, and Menopausal Status in African-American Women.

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.

Adolescent Opioid Misuse Attributable to Adverse Childhood Experiences.

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.

Factors Associated with Neurodevelopmental Impairment in Bronchopulmonary Dysplasia.

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.

Factors Associated with Attention Deficit Hyperactivity Disorder Medication Use in Community Care Settings.

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.

No Difference Between Low- and Regular-dose Aspirin for Venous Thromboembolism Prophylaxis After THA.

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.

Residential Greenspace Association with Childhood Behavioral Outcomes.

OBJECTIVE: To assess the relationship between greenspace exposure and childhood internalizing and externalizing behaviors. STUDY DESIGN: We analyzed data from the Cincinnati Childhood Allergy and Air Pollution Study, an ongoing prospective birth cohort. Greenspace exposure was estimated based on children's addresses using normalized difference vegetation index (NDVI) images. Neurobehavioral outcomes were assessed using the Behavioral Assessment System for Children, Second Edition. Regression models adjusted for neighborhood deprivation, maternal education, race, and sex assessed the risk for problematic internalizing and externalizing behaviors at residential greenspace buffers of 200, 400, and 800 m. RESULTS: There were 562 and 313 children in our age 7- and 12-year analyses, respectively. At age 7 years, a 0.1-unit increase in NDVI was associated with decreased conduct scores (ß = -1.10, 95% CI [-2.14, -0.06], 200 m). At age 12 years, a 0.1-unit increase in NDVI was associated with a decrease in anxiety scores (ß = -1.83, 95% CI [-3.44, -0.22], 800 m), decreased depression scores (ß = -1.36, 95% CI [-2.61, -0.12], 200 m), and decreased somatization scores (ß = -1.83, 95% CI [-3.22, -0.44], 200 m). CONCLUSIONS: This study provides evidence that increased exposure to residential greenspace is associated with reduced youth's problematic internal and external behaviors, measured by Behavioral Assessment System for Children, Second Edition, at ages 7 and 12 years. Improved understanding of this mechanism could allow for implementation of neighborhood-level approaches for reducing the risk for childhood behavioral problems.

Gaps and Factors Related to Receipt of Care within a Medical Home for Toddlers Born Preterm.

OBJECTIVE: To characterize gaps and factors related to receipt of care within a medical home for toddlers born preterm. STUDY DESIGN: Participants were 202 caregivers of children born at <35 weeks of gestation. At 10-16 months of corrected age, caregivers completed the National Survey of Children's Health (2011/2012) medical home module and a sociodemographic profile. Care within a medical home comprised having a personal doctor/nurse, a usual place for care, effective care coordination, family-centered care, and getting referrals when needed. Gestational age and neonatal follow-up clinic attendance were abstracted from the medical record. The Bayley Scales of Infant and Toddler Development, Third Edition assessed developmental status. Log-binomial regression examined factors related to receiving care within a medical home. RESULTS: Fifty-three percent (n = 107) of the children received care within a medical home. Low socioeconomic status (young caregiver: risk ratio [RR] = 0.73; 95% CI 0.55, 0.97; low education: RR= 0.69; 95% CI 0.49, 0.98) and delayed language (RR = 0.63; 95% CI 0.42, 0.95) were associated with a lower likelihood of receiving care within a medical home. Degree of prematurity and neonatal clinic follow-up participation were unrelated to receipt of care within a medical home. CONCLUSIONS: Receipt of care within a medical home was lacking for nearly one-half of preterm toddlers, especially those with lower socioeconomic status and poorer developmental status. Discharge from a neonatal intensive care unit may be an optimal time to facilitate access to a primary care medical home and establish continuity of care. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01576783.

Periconception Exposure to Air Pollution and Risk of Congenital Malformations.

OBJECTIVE: To evaluate the association between increased exposure to airborne fine particulate matter (PM2.5) during the periconception period with risk of congenital anomalies. STUDY DESIGN: Using birth certificate data from the Ohio Department of Health (2006-2010) and PM2.5 data from the US Environmental Protection Agency's 57 monitoring stations located throughout Ohio, the geographic coordinates of the mother's residence for each birth were linked to the nearest PM2.5 monitoring station and monthly exposure averages were calculated. The association between congenital anomalies and increased PM2.5 levels was estimated, with adjustment for coexistent risk factors. RESULTS: After adjustment for coexisting risk factors, exposure to increased levels of PM2.5 in the air during the periconception period was modestly associated with risk of congenital anomalies. Compared with other periconception exposure windows, increased exposure during the 1 month before conception was associated with the highest risk increase at lesser distances from monitoring stations. The strongest influences of PM2.5 on individual malformations were found with abdominal wall defects and hypospadias, especially during the 1-month preconception. CONCLUSIONS: Increased exposure to PM2.5 in the periconception period is associated with some modest risk increases for congenital malformations. The most susceptible time of exposure appears to be the 1 month before and after conception. Although the increased risk with PM2.5 exposure is modest, the potential impact on a population basis is noteworthy because all pregnant women have some degree of exposure.

The Child Opportunity Index and Disparities in Pediatric Asthma Hospitalizations Across One Ohio Metropolitan Area, 2011-2013.

OBJECTIVES: To determine whether the Child Opportunity Index (COI), a nationally available measure of relative educational, health/environmental, and social/economic opportunity across census tracts within metropolitan areas, is associated with population- and patient-level asthma morbidity. STUDY DESIGN: This population-based retrospective cohort study was conducted between 2011 and 2013 in a southwest Ohio county. Participants included all children aged 1-16 years with hospitalizations or emergency department visits for asthma or wheezing at a major pediatric hospital. Patients were identified using discharge diagnosis codes and geocoded to their home census tract. The primary population-level outcome was census tract asthma hospitalization rate. The primary patient-level outcome was rehospitalization within 12 months of the index hospitalization. Census tract opportunity was characterized using the COI and its educational, health/environmental, and social/economic domains. RESULTS: Across 222 in-county census tracts, there were 2539 geocoded hospitalizations. The median asthma-related hospitalization rate was 5.0 per 1000 children per year (IQR, 1.9-8.9). Median hospitalization rates in very low, low, moderate, high, and very high opportunity tracts were 9.1, 7.6, 4.6, 2.1, and 1.8 per 1000, respectively (P < .0001). The social/economic domain had the most variables significantly associated with the outcome at the population level. The adjusted patient-level analyses showed that the COI was not significantly associated with a patient's risk of rehospitalization within 12 months. CONCLUSIONS: The COI was associated with population-level asthma morbidity. The details provided by the COI may inform interventions aimed at increasing opportunity and reducing morbidity across regions.

Achieving Anatomic Acetabular Fracture Reduction-When is the Best Time to Operate?

OBJECTIVES: We hypothesize that earlier operative intervention for acetabular fractures improves the probability of achieving an anatomic reduction. DESIGN: Retrospective review. SETTING: Academic level I trauma center. PATIENTS/PARTICIPANTS: Six hundred fifty acetabular fractures treated through open reduction and internal fixation (ORIF) between September 2001 and February 2014. INTERVENTION: Acetabular fracture ORIF. MAIN OUTCOME MEASUREMENTS: Reduction quality was assessed through postoperative radiographs. Displacement of ≤1 mm was considered an anatomic reduction, 2-3 mm imperfect, and >3 mm poor. RESULTS: Anatomic reductions were observed in 85% (n = 553) of cases, imperfect reductions in 11% (n = 74) of cases, and poor reductions in 4% (n = 23) of cases. Patients with anatomic reductions had significantly shorter times from injury to ORIF [odds ratio (OR) interval] (median, 3 d) when compared with either imperfect (median, 4.5 days, P = 0.02) or poor reductions (median, 7 days, P < 0.001) reductions. The OR interval of imperfect reductions was also significantly shorter than that of poor reductions (P = 0.02). Logistic regression analysis demonstrated that OR interval had an effect of -0.12, meaning that the log odds of anatomic reduction decreases by 0.12 with each day from injury to ORIF. CONCLUSION: The interval from injury to operative fixation of acetabular fractures affects reduction quality. Earlier intervention improves the probability of achieving an anatomic reduction; therefore, ORIF should be performed as early as possible, provided the patient is optimized for surgery. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Areas with High Rates of Police-Reported Violent Crime Have Higher Rates of Childhood Asthma Morbidity.

OBJECTIVES: To assess whether population-level violent (and all) crime rates were associated with population-level child asthma utilization rates and predictive of patient-level risk of asthma reutilization after a hospitalization. STUDY DESIGN: A retrospective cohort study of 4638 pediatric asthma-related emergency department visits and hospitalizations between 2011 and 2013 was completed. For population-level analyses, census tract asthma utilization rates were calculated by dividing the number of utilization events within a tract by the child population. For patient-level analyses, hospitalized patients (n = 981) were followed until time of first asthma-related reutilization. The primary predictor was the census tract rate of violent crime as recorded by the police; the all crime (violent plus nonviolent) rate was also assessed. RESULTS: Census tract-level violent and all crime rates were significantly correlated with asthma utilization rates (both P < .0001). The violent crime rate explained 35% of the population-level asthma utilization variance and remained associated with increased utilization after adjustment for census tract poverty, unemployment, substandard housing, and traffic exposure (P = .002). The all crime rate explained 28% of the variance and was similarly associated with increased utilization after adjustment (P = .02). Hospitalized children trended toward being more likely to reutilize if they lived in higher violent (P = .1) and all crime areas (P = .01). After adjustment, neither relationship was significant. CONCLUSIONS: Crime data could help facilitate early identification of potentially toxic stressors relevant to the control of asthma for populations and patients.

Lasting Effects of the Breast and Cervical Cancer Early Detection Program on Breast Cancer Detection and Outcomes, Ohio, 2000-2009.

INTRODUCTION: The National Breast and Cervical Cancer Early Detection Program (BCCP) in Ohio provides screening and treatment services for uninsured low-income women aged 40 to 64. Because participation in the BCCP might engender greater self-efficacy for cancer screening, we hypothesized that breast cancer and survival outcomes would be better in BCCP participants who become age-eligible to transition to Medicare than in their low-income non-BCCP counterparts. METHODS: Linking data from the 2000 through 2009 Ohio Cancer Incidence Surveillance System with the BCCP database, Medicare files, Ohio death certificates (through 2010), and the US Census, we identified Medicare beneficiaries who were aged 66 to 74 and diagnosed with incident invasive breast cancer. We compared the following outcomes between BCCP women (n = 93) and low-income non-BCCP women (n = 420): receipt of screening mammography in previous year, advanced-stage disease at diagnosis, timely and standard care, all-cause survival, and cancer survival. We conducted multivariable logistic regression and survival analysis to examine the association between BCCP status and each of the outcomes, adjusting for patient covariates. RESULTS: Women who participated in the BCCP were nearly twice as likely as low-income non-BCCP women to have undergone screening mammography in the previous year (adjusted odds ratio, 1.77; 95% confidence interval, 1.01-3.09). No significant differences were detected in any other outcomes. CONCLUSION: With the exception of screening mammography, the differences in outcomes were not significant, possibly because of the small size of the study population. Future analysis should be directed toward identifying the factors that explain these findings.

Significant Reduction of Central-Line Associated Bloodstream Infections in a Network of Diverse Neonatal Nurseries.

OBJECTIVE: To describe a quality improvement (QI) initiative that was associated with a dramatic reduction in neonatal central-line associated bloodstream infection (CLABSI) rate in a diverse group of 8 intensive care nurseries (Neonatal Services). STUDY DESIGN: A quasi-experimental time series QI initiative using the model for improvement and evidenced-based interventions. RESULTS: The aggregate CLABSI rate for Nationwide Children's Hospital-associated Neonatal Services decreased from 6.0 CLABSI per 1000 catheter days to 1.43 CLABSI per 1000 catheter days in less than 2 years and has remained in control at 0.68 per 1000 catheter days for over 5 years. Each of 8 nurseries has had a 1 year or more CLABSI-free period, including the neonatal intensive care unit with the largest patient volume, acuity, and central line usage. Aggregate Neonatal Services has experienced 3 CLABSI-free quarters since 2007. Key success factors included: (1) engagement of senior executive leadership; (2) bedside "huddles" among clinical and epidemiology staffs conducted within 72 hours after a positive blood culture; (3) implementation of chlorhexidine antisepsis and the use of chlorhexidine-impregnated catheter site discs; and (4) and establishment of a dedicated team for percutaneously inserted central catheter insertion to serve units in which central lines are placed less frequently. CONCLUSIONS: Using the model for improvement and evidenced-based interventions, this QI project has been associated with reduction in the CLABSI rate by 89%, and over 430 CLABSIs likely have been avoided.

Adolescent and young adult female determinants of visceral adipose tissue at ages 26-28 years.

OBJECTIVE: To assess adolescent and young adult determinants of visceral adipose tissue (VAT) at ages 26-28 years. STUDY DESIGN: Prospective study (ages 9-28 years) of cardiometabolic measures, menarche age, menses irregularities, metabolic syndrome, impaired fasting glucose-type 2 diabetes mellitus, and VAT in 400 girls (248 black, 152 white). RESULTS: Adolescent (age 14-19) independent variables for greater VAT at ages 26-28 included larger mean waist circumference (partial R(2) = 30.8%), earlier age at menarche (0.9%), and white race (1.8%). Young adult (ages 20-28 years) independent variables for greater VAT included larger mean waist circumference (partial R(2) = 61.7%), greater triglyceride levels (3.3%), lower high-density lipoprotein cholesterol (1.0%), and greater insulin resistance (homeostasis model assessment-estimated insulin resistance; 0.4%). Independent variables for greater VAT when both adolescent and young adult variables were used included waist (tertile rank change from adolescence to young adulthood, partial R(2) = 58.3%), greater young adult triglyceride levels (4.4%), white race (1.8%), greater young adult homeostasis model assessment-estimated insulin resistance (age 20-28, 2.4%), and earlier menarche age (0.7%). Menses irregularities were not independently associated with young adult VAT. CONCLUSIONS: Adolescent girls with early menarche and larger waist circumference should be targets for primary prevention of accretion of VAT. In young adulthood, VAT is associated with dysregulated cardiometabolic profiles, which is greater for those with waist circumference increases from adolescence to adulthood. Waist circumference during young adulthood, and to a lesser degree during adolescence, is an inexpensive surrogate for VAT at ages 26-28 years.

Mortality among chemical plant workers exposed to acrylonitrile: 2011 follow-up.

OBJECTIVES: To update a cohort study of chemical workers and reevaluate lung cancer mortality in relation to acrylonitrile (AN) exposure. METHODS: Subjects were 2096 workers employed during 1955 to 2011. We identified 474 deaths through 2011, and quantitatively estimated worker exposures to AN. Analyses included national and county-based standardized mortality ratios and relative risk regression of internal cohort rates. RESULTS: We found no statistically significant excess mortality risks associated with Lima employment for any cause of death category, including lung cancer and other cancer sites implicated in previous studies. CONCLUSIONS: This update provides no evidence that exposure to AN at levels experienced by Lima workers is associated with an increased risk of lung cancer mortality, as suggested in original study. Earlier reported bladder cancer risks decreased to a much lower, not statistically significant level.

Evaluation of potential confounding by smoking in the presence of misclassified smoking data in a cohort study of workers exposed to acrylonitrile.

OBJECTIVES: To evaluate the extent to which lung cancer mortality risk estimates in relation to acrylonitrile (AN) exposure may have been confounded by smoking in the presence of misclassified smoking data. METHODS: Subjects were 992 white men employed for three or more months between 1960 and 1996 at a chemical plant in Lima, Ohio. We used Monte Carlo-based sensitivity analysis to address possible confounding by smoking. RESULTS: In Monte Carlo simulations that accounted for the relationship between smoking and AN exposure, mean relative risks for lung cancer mortality in relation to AN exposure decreased and we observed somewhat less evidence of an exposure-response relationship. CONCLUSIONS: Our simulations suggest that the relationship between AN exposure and lung cancer mortality was positively confounded by smoking in the original Lima cohort study.

High school principals' resources, knowledge, and practices regarding the returning student with concussion.

OBJECTIVE: To determine high school principals' self-reported resources, knowledge, and practices regarding the management of students returning to school following concussion. STUDY DESIGN: A cross-sectional survey of public high school principals in the state of Ohio assessed respondent and school demographics, respondent concussion training, school resources, and monitoring and accommodation practices for students with concussion. RESULTS: Of the 695 eligible high school principals, 465 (66.9%) completed the survey. Over one-third of principals (37.2%) had some form of concussion training in the past year. Those with training were more likely to promote training of other school faculty (57.4% vs 30.6%, P < .001). Principals were asked to identify school personnel who are designated as case managers for students with concussion. Schools without a designated case manager were less likely to have an athletic trainer (P < .001) and had fewer students (median 424.5 vs 599) than schools with a case manager. Principals could list at least 1 faculty designee who communicates with health professionals more often for student-athletes than for nonathletes (P < .001). Most principals were willing to provide students with short-term academic accommodations, but 30.1% required a health professional's note prior to making any academic changes. Only 32% of principals reported providing families with a written academic plan following concussion. CONCLUSIONS: Schools differ in their resources and management strategies for students returning to school after concussion. Understanding these differences can help health professionals to overcome potential barriers in managing their school-aged patients with concussion.

Universal maternal drug testing in a high-prevalence region of prescription opiate abuse.

OBJECTIVE: To evaluate the efficacy of a universal maternal drug testing protocol for all mothers in a community hospital setting that experienced a 3-fold increase in neonatal abstinence syndrome (NAS) over the previous 5 years. STUDY DESIGN: We conducted a retrospective cohort study between May 2012 and November 2013 after the implementation of universal maternal urine drug testing. All subjects with positive urine tests were reviewed to identify a history or suspicion of drug use, insufficient prenatal care, placental abruption, sexually transmitted disease, or admission from a justice center, which would have prompted urine testing using our previous risk-based screening guidelines. We also reviewed the records of infants born to mothers with a positive toxicology for opioids to determine whether admission to the special care nursery was required. RESULTS: Out of the 2956 maternal specimens, 159 (5.4%) positive results were recorded. Of these, 96 were positive for opioids, representing 3.2% of all maternity admissions. Nineteen of the 96 (20%) opioid-positive urine tests were recorded in mothers without screening risk factors. Seven of these 19 infants (37%) required admission to the special care nursery for worsening signs of NAS, and 1 of these 7 required pharmacologic treatment. CONCLUSION: Universal maternal drug testing improves the identification of infants at risk for the development of NAS. Traditional screening methods underestimate in utero opioid exposure.

Phenotypic and Genotypic Characterization of Salmonella enterica in Captive Wildlife and Exotic Animal Species in Ohio, USA.

The purpose of this study was to investigate the occurrence, antimicrobial resistance patterns, phenotypic and genotypic relatedness of Salmonella enterica recovered from captive wildlife host species and in the environment in Ohio, USA. A total of 319 samples including faecal (n = 225), feed (n = 38) and environmental (n = 56) were collected from 32 different wild and exotic animal species in captivity and their environment in Ohio. Salmonellae were isolated using conventional culture methods and tested for antimicrobial susceptibility with the Kirby-Bauer disc diffusion method. Salmonella isolates were serotyped, and genotyping was performed using the pulsed-field gel electrophoresis (PFGE). Salmonella was detected in 56 of 225 (24.9%) faecal samples; six of 56 (10.7%) environmental samples and six of 38 (15.8%) feed samples. Salmonella was more commonly isolated in faecal samples from giraffes (78.2%; 36/46), cranes (75%; 3/4) and raccoons (75%; 3/4). Salmonella enterica serotypes of known public health significance including S. Typhimurium (64.3%), S. Newport (32.1%) and S. Heidelberg (5.3%) were identified. While the majority of the Salmonella isolates were pan-susceptible (88.2%; 60 of 68), multidrug-resistant strains including penta-resistant type, AmStTeKmGm (8.8%; six of 68) were detected. Genotypic diversity was found among S. Typhimurium isolates. The identification of clonally related Salmonella isolates from environment and faeces suggests that indirect transmission of Salmonella among hosts via environmental contamination is an important concern to workers, visitors and other wildlife. Results of this study show the diversity of Salmonella serovars and public health implications of human exposure from wildlife reservoirs.
