Improvements in swine herd biosecurity reduce the incidence risk of porcine reproductive and respiratory syndrome virus in breeding herds in the Midwestern United States.

OBJECTIVE: Porcine reproductive and respiratory syndrome (PRRS) is a significant disease of swine. The purpose of this study was to determine whether application of a comprehensive, science-based approach to breeding herd biosecurity, known as next-generation biosecurity (NGB), could reduce PRRS incidence risk across a large commercial production company. ANIMALS: Pigs (381,404 sows across 76 breeding herds). METHODS: From 2009 to 2020, the annual incidence risk of PRRS in sow farms managed by the same company averaged 33%, ranging from 20% to 50%. To measure the effect of NGB on PRRS incidence risk, a retrospective cohort study was conducted from July 1, 2021, to June 30, 2023, across breeding herds managed by the same company. During the analysis, 2 groups of herds emerged: those that implemented protocols for all phases of NGB (NGB COMPLETE), and those that implemented all described protocols of biosecurity except for air filtration (NGB INCOMPLETE). RESULTS: During the 2-year assessment period, 56 breeding herds were classified as NGB COMPLETE, while 20 herds were NGB INCOMPLETE. The PRRS incidence risk in NGB COMPLETE herds was 8.9% as compared to 40.0% in NGB INCOMPLETE herds. From disease year 1 (July 1, 2021, to June 30, 2022) and disease year 2 (July 1, 2022, to June 30, 2023), system-wide PRRS incidence risk was 8.6% and 9.2%, respectively. The association between NGB status and PRRS incidence risk for the 2-year period was statistically significant at a P value of .006. CLINICAL RELEVANCE: Results of the present report provided evidence that improvements in biosecurity result in lower PRRS incidence risk under large-scale commercial swine production conditions.

Tractor Injuries in the Upper Midwestern United States: a retrospective analysis of four trauma centers.

OBJECTIVES: The purpose of the present study was to characterize the incidence, injury characteristics, and outcomes of patients presented to four trauma facilities located in the upper Midwest with tractor-related agricultural injuries. METHODS: We performed a retrospective review of the facility level trauma registries of four trauma centers located in North Dakota, South Dakota, and Minnesota between January 1, 2010 and December 31, 2021. We characterized the incidence, severity and outcomes of traumatic tractor-related agricultural injuries for pediatric and adult patients. We described the nature of these injuries by severity, anatomical site, type, age, sex, and length of stay (LoS). Injury severity was evaluated using Injury Severity Score (ISS) and Abbreviated Injury Scale (AIS). RESULTS: Findings indicated that farmers aged 65 and older experience polytraumatic, severe tractor-related agricultural injuries and fatalities. Of the 177 tractor patients analyzed, 40 patients were between the ages of 65 and 74 years and 45 patients were 75 and over. Male farmers aged 65 and older are injured year-round, many are discharged to skilled nursing facilities for additional care, are spending more time in the hospital, and have the highest rate of critical injuries out of all age groups. Moreover, the patients who died as a result of tractor-related agricultural injuries were men over 65 years. The most common tractor-related agricultural injuries include falls from tractors (n = 53), struck by object falling/propelled from tractor (n = 25), rollovers (n = 26), and runovers (n = 24). Falls from tractors accounted for 33% of all tractor-related upper extremity fractures, 36% of head injuries and 29% of chest injuries. CONCLUSION: The findings from this study indicate that tractor-related agricultural injuries represent a significant problem in the upper Midwest. Older, male farm workers experience a higher incidence of tractor-related agricultural injuries, and all tractor-related fatalities occurred in individuals 65 years of age and older. These results underscore the need for further investigation into aging-related farm safety issues.

Dermatophytosis is uncommon in asymptomatic wild eastern cottontail rabbits in Illinois, Midwestern United States.

OBJECTIVE: To investigate the presence of dermatophytes on the haircoat of wild eastern cottontail rabbits (ECR) (Sylvilagus floridanus) with and without skin lesions. ANIMALS: 2-week-old or older ECR admitted to a Wildlife Medical Clinic (WMC) in central Illinois, Midwest United States, from September 2021 to August 2022. METHODS: ECR were surveyed over a 1-year period to assess the prevalence and seasonality of dermatophytosis. A Wood's lamp exam was performed over the haircoat. Hairs were sampled with a sterile toothbrush and plated on Sabouraud dextrose agar. The plates were photographed twice weekly for 3 weeks, and colonies were identified as contaminants or dermatophytes. RESULTS: 523 ECR were admitted to WMC, 141 ECR met the age inclusion criteria, and 121 samples were plated. ECR presented as a litter were sampled together. None of the sampled ECR presented skin lesions other than acute traumatic wounds. No fluorescence was observed on any ECR during the Wood's lamp examination. Based on culture colony morphology, 115/121 of the samples were identified as contaminants and no growth was observed in 6/121 of plates. Dermatophytes' colonies were not identified on any of the culture plates. CLINICAL RELEVANCE: Dermatophytes are zoonotic fungi and can potentially be carried by wild animals. The fungal infection poses a health concern to humans and domestic pets through direct interaction. Our current results suggest that dermatophytosis may not be prevalent in asymptomatic wild rabbits in the studied areas of the Midwestern United States.

Anemia In Pregnancy: Examining Missed Diagnoses and Racial Disparities in the Upper Midwest.

Anemia in pregnancy (AIP) is associated with poor maternal/fetal outcomes. The prevalence of AIP globally ranges from 44-53% and varies drastically depending on maternal race/ethnicity and other factors. Screening and treatment of AIP is disputed. This study is a retrospective review of electronic medical records (EMR) of pregnant adults over three years (2018-2020, inclusive) of Sanford Health, a large healthcare system in the upper Midwest. AIP was determined by either diagnosis or lab values (hemoglobin, hematocrit, and ferritin) overlapping with pregnancy. A missed diagnosis was characterized by confirmed anemia through lab values but lacking a diagnosis of anemia within EMR. A total of 35,498 patients were included in this study, 42.9% were determined to have AIP. Of AI/AN (American Indian/Alaska Native) patients, 58.3% were anemic and 55.1% of Black/African American patients were anemic compared to 40.0% of anemic white patients. Of anemic patients, 81.1% did not have an anemia diagnosis listed in EMR. This study identifies racial and ethnic disparities of AIP among patients in the upper Midwest. In addition, this study highlights the need for improved data integrity within EMR.

PrEP Persistence Support and Monitoring in Areas of High HIV Burden in the Midwestern United States.

Monitoring pre-exposure prophylaxis (PrEP) metrics can guide service delivery yet does not occur routinely. We developed a survey to understand current practices for monitoring PrEP at PrEP-providing organizations in Illinois and Missouri. The survey was distributed from September through November 2020; 26 organizations participated. Most respondents indicated ongoing efforts to screen for PrEP eligibility (66.7%), link to care (87.5%), and retain clients in care (70.8%); 70.8% reported collecting data on PrEP initiation, 41.7% on retention in care, and 37.5% on missed visits. Barriers to monitoring PrEP metrics included lack of IT support (69.6%), manual processes (69.6%), and lack of staff resources (65.2%). Most respondents offered clients support for PrEP retention and adherence and wanted to expand interventions for PrEP persistence, yet fewer monitored corresponding metrics. To enhance PrEP implementation, organizations should improve monitoring and evaluation of PrEP metrics along the entire continuum and respond with appropriate services to support clients.

Rural and urban residents' attitudes and preferences toward COVID-19 prevention behaviors in a midwestern community.

Rural populations are more vulnerable to the impacts of COVID-19 compared to their urban counterparts as they are more likely to be older, uninsured, to have more underlying medical conditions, and live further from medical care facilities. We engaged the Southeastern MN (SEMN) community (N = 7,781, 51% rural) to conduct a survey of motivators and barriers to masking to prevent COVID-19. We also assessed preferences for types of and modalities to receive education/intervention, exploring both individual and environmental factors primarily consistent with Social Cognitive Theory. Our results indicated rural compared to urban residents performed fewer COVID-19 prevention behaviors (e.g. 62% rural vs. 77% urban residents reported wearing a mask all of the time in public, p<0.001), had more negative outcome expectations for wearing a mask (e.g. 50% rural vs. 66% urban residents thought wearing a mask would help businesses stay open, p<0.001), more concerns about wearing a mask (e.g. 23% rural vs. 14% urban were very concerned about being 'too hot', p<0.001) and lower levels of self-efficacy for masking (e.g. 13.9±3.4 vs. 14.9±2.8, p<0.001). It appears that masking has not become a social norm in rural SEMN, with almost 50% (vs. 24% in urban residents) disagreeing with the expectation 'others in my community will wear a mask to stop the spread of Coronavirus'. Except for people (both rural and urban) who reported not being at all willing to wear a mask (7%), all others expressed interest in future education/interventions to help reduce masking barriers that utilized email and social media for delivery. Creative public health messaging consistent with SCT tailored to rural culture and norms is needed, using emails and social media with pictures and videos from role models they trust, and emphasizing education about when masks are necessary.

Risk factors associated with sow mortality in breeding herds under one production system in the Midwestern United States.

Sow mortality has significantly increased throughout the world over the past several years, and it is a growing concern to the global swine industry. Sow mortality increases economic losses, including higher replacement rates, affects employees' morale, and raises concerns about animal well-being and sustainability. This study aimed to assess herd-level risk factors associated with sow mortality in a large swine production system in the Midwestern United States. This retrospective observational study used available production, health, nutritional, and management information between July 2019 and December 2021. A Poisson mixed regression model was used to identify the risk factors and to build a multivariate model using the weekly mortality rate per 1000 sows as the outcome. Different models were used to identify the risk factors according to this study's main reasons for sow mortality (total death, sudden death, lameness, and prolapse). The main reported causes of sow mortality were sudden death (31.22 %), lameness (28.78 %), prolapse (28.02 %), and other causes (11.99 %). The median (25th-75th percentile) distribution of the crude sow mortality rate/1000 sows was 3.37 (2.19 - 4.16). Breeding herds classified as epidemic for porcine reproductive and respiratory syndrome virus (PRRSV) were associated with higher total death, sudden death, and lameness death. Open pen gestation was associated with a higher total death and lameness compared with stalls. Pulses of feed medication was associated with lower sow mortality rate for all outcomes. Farms not performing bump feeding were associated with higher sow mortality due to lameness and prolapses, while Senecavirus A (SVA)-positive herds were associated with a higher mortality rate for total deaths and deaths due to lameness. Disease interactions (herds Mycoplasma hyopneumoniae positive and epidemic for PRRSV; SVA positive herds and epidemic for PRRSV) were associated with higher mortality rates compared to farms with single disease status. This study identified and measured the major risk factors associated with total sow mortality rate, sudden deaths, lameness deaths, and prolapse deaths in breeding herds under field conditions.

Barriers and opportunities for promoting health professions careers among African American students in the Midwest.

The purpose of our study is to examine the barriers and facilitators for urban African American students interested in pursuing health professions careers in the Midwest. In our analysis of the key informant interviews and focus groups, we identified four barriers (lack of preparation, lack of funding, lack of support/isolation, and perceived discrimination) and three facilitators (early preparation, support/mentorship, funding). We provide recommendations for how to leverage these facilitators and address the barriers to increase the representation of African Americans in the healthcare workforce. Novel future directions for this work should include comprehensive interventions tailored to URM students that span the health professions education pipeline and begin as early as elementary school. Interventions that engage mentors should take place at high school, undergraduate, and graduate health professions school levels.

The relationship between state-level structural racism and disparities between the non-hispanic black and non-hispanic white populations in multiple health outcomes.

AIMS: While several studies have examined the impact of individual indicators of structural racism on single health outcomes, few have explicitly modeled racial disparities in a wide range of health outcomes using a multidimensional, composite structural racism index. This paper builds on the previous research by examining the relationship between state-level structural racism and a wider array of health outcomes, focusing on racial disparities in mortality from firearm homicide, infant mortality, stroke, diabetes, hypertension, asthma, HIV, obesity, and kidney disease. METHODS: We used a previously developed state structural racism index that consists of a composite score derived by averaging eight indicators across five domains: (1) residential segregation; (2) incarceration; (3) employment; (4) economic status/wealth; and (5) education. Indicators were obtained for each of the 50 states using Census data from 2020. We estimated the Black-White disparity in each health outcome in each state by dividing the age-adjusted mortality rate for the non-Hispanic Black population by the age-adjusted mortality rate for the non-Hispanic White population. These rates were obtained from the CDC WONDER Multiple Cause of Death database for the combined years 1999-2020. We conducted linear regression analyses to examine the relationship between the state structural racism index and the Black-White disparity in each health outcome across the states. In multiple regression analyses, we controlled for a wide range of potential confounding variables. RESULTS: Our calculations revealed striking geographic differences in the magnitude of structural racism, with the highest values generally being observed in the Midwest and Northeast. Higher levels of structural racism were significantly associated with greater racial disparities in mortality for all but two of the health outcomes. CONCLUSIONS: There is a robust relationship between structural racism and Black-White disparities in multiple health outcomes across states. Programs and policies to reduce racial heath disparities must include strategies to help dismantle structural racism and its consequences.

Prevalence of Educationally Significant Disabilities Among Deaf and Hard of Hearing Students.

Deaf and hard of hearing (d/DHH) students are often labeled with one or more educationally significant disabilities in addition to their hearing loss. According to the Gallaudet Research Institution's most recent Annual Survey of Deaf and Hard of Hearing Children and Youth (2013), almost 40% of d/DHH students nationwide receive special education services for one or more comorbid disabilities. However, relatively few prevalence rate estimates have been published over the last decade. Knowledge regarding the current prevalence of educationally significant disabilities among d/DHH students is therefore limited. The present study surveyed teachers of the deaf and hard of hearing (TODHHs) in a midwestern state regarding the number of d/DHH students on their caseloads with one or more comorbid disabilities. Within the sample population (N = 451), nearly 65% were reported to receive special education services for disabilities other than deafness or hearing impairment.

Novel hepatoviruses in synanthropic bats in the upper Midwestern United States.

A nearly complete genome sequence of hepatovirus G was isolated from an Eptesicus fuscus bat submitted for rabies virus testing due to human exposure in South Dakota. The predicted polyprotein sequence was 78.2% and 74.4% identical to genotypes G1 and G2, respectively, recovered from bats in Ghana. Quantitative PCR on 90 E. fuscus bats showed that eight (8.9%) were positive for hepatovirus G. Targeted sequencing of the VP2 region of the genome for five positive samples showed >99% identity to hepatovirus G strain Ef15893, demonstrating that hepatovirus G commonly circulates in E. fuscus bats in the upper Midwest.

Sleep of infants and toddlers during 12 months of the COVID-19 pandemic in the midwestern United States.

STUDY OBJECTIVES: Cultural sleep practices and COVID-19 mitigation strategies vary worldwide. The sleep of infants and toddlers during the COVID-19 pandemic in the United States is understudied. METHODS: Caregivers of children aged < 3 years responded to a cross-sectional survey during 2020 (divided into quarters, with the year quarter 1 being largely prelockdown). We assessed the global effect of year quarter on parent-reported total sleep time (hours) and sleep onset latency (hours) using an analysis of variance. We used multivariable linear regression to assess the adjusted effect of year quarter on total sleep time, sleep onset latency, and parental frustration. We used logistic regression to assess the adjusted effect of year quarter on nap consistency. RESULTS: Of 594 children, the mean age was 18.5 ± 9.7 months; 52% were female. In the adjusted analyses, the reference categories were as follows: quarter 1 (year quarter), ≤ 6 months (age category), and < $25,000 (annual household income). Total sleep time was associated with age category (ages 12 to ≤ 24 months: ß = -2.86; P = .0004; ages 24 to ≤ 36 months: ß = -3.25; P < .0001) and maternal age (ß = -0.04; P = .05). Sleep onset latency was associated with year quarter (year quarter 3: ß = 0.16; P = .04), age category (ages 24 to ≤ 36 months: ß = 0.28; P < .0001), annual household income ($100,000-$150,000: ß = -0.15; P = .03; > $150,000: ß = -0.19; P = .01), and lack of room-sharing (ß = -0.09; P = .05). Parental frustration with sleep increased with age (all P < .05) and lack of room-sharing (P = .01). The effect of lack of room-sharing on nap consistency approached significance (adjusted odds ratio, 1.88; 95% confidence interval, 0.95-3.72). CONCLUSIONS: Social factors such as lower household income and room-sharing affected the sleep of U.S. infants and toddlers as opposed to the COVID-19 lockdown itself.

Active environmental surveillance of SARS-CoV-2 in Midwestern United States meatpacking plants.

This pilot project investigated environmental SARS-CoV-2 presence in seven Midwestern meatpacking plants from May 2020 to January 2021. This study investigated social distancing and infection control practices and incorporated environmental sampling of surfaces and air in employee common areas. All plants increased their social distancing efforts, increased the frequency of cleaning and disinfecting worker areas, and screened for symptomatic people to prevent entry into the workplace. 575 samples from common areas were collected and evaluated with RT-qPCR for the presence of SARS-CoV-2. 42/367 surface samples were positive, while no virus was detected in air samples. Case positive data from the counties surrounding each plant showed peak positive SARS-CoV-2 cases from 12-55 days before the virus was detected in the plant, indicating that environmental sampling is likely a lagging indicator of community and plant infection.

Incidence and Long-Term Outcomes of Stroke in Patients Presenting With ST-Segment Elevation-Myocardial Infarction: Insights From the Midwest STEMI Consortium.

Background Contemporary real-world data on stroke in patients presenting with ST-segment-elevation myocardial infarction (STEMI) are scarce. Methods and Results We evaluated the incidence, trends, cause, and predictors of stroke from 2003 to 2019 in 4 large regional STEMI programs in the upper Midwest that use similar transfer and treatment protocols. We also evaluated the long-term impact of stroke on 5-year mortality. Multivariate logistic and Cox regression analysis was used to identify variables independently associated with stroke in patients presenting with STEMI and identify variables associated with 5-year mortality. A total of 12 868 patients presented with STEMI during the study period. Stroke occurred in 98 patients (0.76%). The incidence of stroke remained stable over time (0.5% in 2003, 1.2% in 2019; P-trend=0.22). Most (75%) of strokes were ischemic, with a median time to stroke symptoms of 14 hours after primary percutaneous coronary intervention (interquartile range, 4-72 hours), which led to a small minority (3%) receiving endovascular treatment and high in-hospital mortality (18%). On multivariate regression analysis, age (increment of 10 years) (odds ratio [OR], 1.32; 95% CI, 1.10-1.58; P-value=0.003) and preintervention cardiogenic shock (OR, 2.03; (95% CI, 1.03-3.78; P=0.032)) were associated with a higher risk of in-hospital stroke. In-hospital stroke was independently associated with increased risk of 5-year mortality (hazard ratio, 2.01; 95% CI, 1.13-3.57; P=0.02). Conclusions In patients presenting with STEMI, the risk of stroke is low (0.76%). A stroke in patients presenting with STEMI is associated with significantly higher in-hospital (18%) and long-term mortality (35% at 5 years). Stroke was associated with double the risk of 5-year death.

Occupational stress among farm and ranch operators in the midwestern United States.

BACKGROUND: This study used surveillance data from 2018 and 2020 to test the stability of work-related strain symptoms (high stress, sleep deprivation, exhaustion) with demographic factors, work characteristics, and musculoskeletal symptoms among farm and ranch operators in seven midwestern states of the United States. METHODS: Cross-sectional surveys were conducted among farm and ranch operators in 2018 (n = 4423) and 2020 (n = 3492). Operators were asked whether, in the past 12 months, they experienced extended work periods that resulted in high stress levels, sleep deprivation, exhaustion/fatigue, or other work-related strain symptoms. Covariates included personal and demographic factors, work characteristics, number of injuries, work-related health conditions, and exposures on the operation. Summary statistics were tabulated for explanatory and outcome variables. The classification (decision) tree approach was used to assess what variables would best separate operators with and without reported strain symptoms, based on a set of explanatory variables. Regularized regression was used to generate effect estimates between the work strain variables and explanatory variables. RESULTS: High stress level, sleep deprivation, and exhaustion were reported more frequently in 2018 than 2020. The classification tree reproduced the 2018 model using 2020 data with approximately 80% accuracy. The mean number of reported MSD symptoms increased slightly from 1.23 in 2018 to 1.41 in 2020. Older age, more time spent in farm work, higher gross farm income (GFI), and MSD symptoms in six body regions (ankles/feet, knees, lower back, neck, shoulders, wrists/hands) were associated with all three work strain symptoms. CONCLUSIONS: Musculoskeletal pain and discomfort was a strong predictor for stress, sleep deprivation, and exhaustion among farmers and ranchers. This finding indicates that reducing MSD pain and discomfort is beneficial for both physical and mental health.

The impact of COVID-19 on patient safety attendant use.

ABSTRACT: Patient safety attendants (PSAs) provide constant direct observation to patients who have cognitive impairments or thoughts. Some estimates report that an acute care hospital in the United States may spend more than $1 million annually on PSAs, an expenditure often not reimbursed. With no national defined standards to regulate or monitor PSA use, this study sought to determine the impact of COVID-19 on a PSA reduction program in a large Midwestern healthcare system.

Race, Ethnicity, Neighborhood Characteristics, and In-Hospital Coronavirus Disease-2019 Mortality.

BACKGROUND: Despite many studies reporting disparities in coronavirus disease-2019 (COVID-19) incidence and outcomes in Black and Hispanic/Latino populations, mechanisms are not fully understood to inform mitigation strategies. OBJECTIVE: The aim was to test whether neighborhood factors beyond individual patient-level factors are associated with in-hospital mortality from COVID-19. We hypothesized that the Area Deprivation Index (ADI), a neighborhood census-block-level composite measure, was associated with COVID-19 mortality independently of race, ethnicity, and other patient factors. RESEARCH DESIGN: Multicenter retrospective cohort study examining COVID-19 in-hospital mortality. SUBJECTS: Inclusion required hospitalization with positive SARS-CoV-2 test or COVID-19 diagnosis at three large Midwestern academic centers. MEASURES: The primary study outcome was COVID-19 in-hospital mortality. Patient-level predictors included age, sex, race, insurance, body mass index, comorbidities, and ventilation. Neighborhoods were examined through the national ADI neighborhood deprivation rank comparing in-hospital mortality across ADI quintiles. Analyses used multivariable logistic regression with fixed site effects. RESULTS: Among 5999 COVID-19 patients median age was 61 (interquartile range: 44-73), 48% were male, 30% Black, and 10.8% died. Among patients who died, 32% lived in the most disadvantaged quintile while 11% lived in the least disadvantaged quintile; 52% of Black, 24% of Hispanic/Latino, and 8.5% of White patients lived in the most disadvantaged neighborhoods.Living in the most disadvantaged neighborhood quintile predicted higher mortality (adjusted odds ratio: 1.74; 95% confidence interval: 1.13-2.67) independent of race. Age, male sex, Medicare coverage, and ventilation also predicted mortality. CONCLUSIONS: Neighborhood disadvantage independently predicted in-hospital COVID-19 mortality. Findings support calls to consider neighborhood measures for vaccine distribution and policies to mitigate disparities.
