Purpose: The purpose of this study was to explore the relationships between hearing loss, cognitive status, and a range of health outcomes over a period of 2 years in a sample of older adults who are enrolled in Program of All-Inclusive Care for the Elderly, which is a Medicare/Medicaid beneficiary program for individuals who are nursing home eligible but living in the community at time of enrollment., Method: The sample ( N = 144) includes a diverse (47% White/non-Hispanic, 35% Black/African American, and 16% Latin/Hispanic) group of adults ranging from 55 to 93 years old. We used medical chart data to measure respondents' cognitive and health status, including chronic conditions and hospital use. Hearing status was measured once at the beginning of the 2-year review period. We used logistic regression and negative binomial hurdle models for analyses. We used latent class analysis (LCA) to explore the extent to which respondents cluster into a set of "health profiles" characterized by their hearing, cognitive status, and health conditions., Results: We found that hearing loss is weakly associated with heart disease and diabetes and associated with cerebrovascular disease and falls; cognitive impairment is also associated with cerebrovascular disease and the number of falls. LCA indicates that respondents cluster into a variety of health profiles with a consistent pairing of hearing loss and depression., Conclusions: The results are largely consistent with associations reported in epidemiological studies that include age-related hearing loss. Of particular interest in this study is the LCA that suggested that all of the profiles associated with a high likelihood of hearing loss included a high risk of depression. The co-occurrence of these two factors highlights the need to identify and treat hearing loss in older adults, especially as part of the treatment plan for individuals with depressive symptoms. more...

Wheeled mobility and seating (WMS) devices allow users to achieve greater mobility independence. Previous studies determined that 53% of wheelchair users required one or more repairs over a 6-month period; however, there are a limited number of studies that have evaluated types of repairs. The purpose of this study was to describe the types of manual wheelchair, power wheelchair, and scooter repairs within the Wheelchair Repair Registry (WRR) and examine the association between WMS devices and the frequency of repairs. A dataset of 4,645 devices distributed in the United States was collected from equipment suppliers who performed and logged community-based wheelchair repair services. The results demonstrated common repairs found across devices were within the wheels/tires/forks and batteries/cables categories. Device type was the most significant predictor of variance in the number of repairs. Customizable manual wheelchairs, tilt-in-space, Groups 2 & 3 power wheelchairs, and scooters were associated with higher number of repairs compared to non-customizable manual wheelchairs, pediatric, heavy-duty manual wheelchairs, and Group 4 power wheelchairs. The higher failure rate found in specific devices may be associated with a population of more active users, environment/conditions where equipment is used, time spent in equipment, additional features on device, or lower durability. more...

Low birth weight and preterm births vary by state, and Black mothers typically face twice the risk that their white counterparts do. This gap reflects an accumulation of psychosocial and material exposures that include interpersonal racism, differential experience with area-level deprivation such as residential segregation, and other harmful exposures that the authors refer to as "institutional" or "structural" racism. The authors use logistic regression models and a dataset that includes all births from 1994 to 2017 as well as five state policies from this period-Aid to Families with Dependent Children/Temporary Aid for Needy Families, housing assistance, Medicaid, minimum wage, and the earned income tax credit (EITC)-to examine whether these state social policies, designed to provide a financial safety net, are associated with risk reduction of low birth weight and preterm birth to Black and white mothers, and whether variations in state generosity attenuate the racial inequalities in birth outcomes. The authors also examine whether the relationship between state policies and racial inequalities in birth outcomes is moderated by the education level of the mother. We find that the EITC reduces the risk of low birth weight and preterm birth for Black mothers. The impact is much less consistent for white mothers. For both Black and white mothers, the benefits to birth outcomes are larger for mothers with less education., (Copyright © 2022 by Duke University Press.) more...

Objective: Referrals are an important component of patient care, and have been increasing over time. During pregnancy, people have intensive contact with the healthcare system, but little is known about the involvement of different physicians for pregnant patients during this period. This study examines referral patterns during prenatal care visits., Methods: Using the 2006-2015 National Ambulatory Medical Care Survey and national birth certificate data, we estimate the number of referrals per pregnancy from prenatal care visits with OB/GYN and family medicine physicians. We use multivariable regression analysis to compare the probability of receiving a referral during a prenatal visit for visits with family medicine and OB/GYN physicians, controlling for visit, patient, and physician characteristics. Analyses are weighted to make results nationally representative., Results: 224,335,436 prenatal visits over 19,893,015 pregnancies were included; 60% of these visits were covered by private insurance. On average, 0.3 referrals are made per pregnancy (95% confidence interval [CI] 0.22, 0.38). A prenatal visit with an OB was 5.5% points less likely to result in a referral than a visit with a family medicine physician, controlling for other characteristics., Conclusions: Referrals are relatively common in prenatal care, and are more commonly initiated by family medicine physicians than by OB/GYNs. Understanding the contribution of multiple clinicians to a pregnant person's health during the prenatal period and how coordination among clinicians impacts care receipt is an important next step. As healthcare becomes more specialized, better understanding care teams of individuals during the perinatal period is important for improving prenatal care., (© 2021.

Introduction: A total of 3.6 million Americans and over 250,000 veterans use wheelchairs. The need for advancements in mobility-assistive technologies is continually growing due to advances in medicine and rehabilitation that preserve and prolong the lives of people with disabilities, increases in the senior population, and increases in the number of veterans and civilians involved in conflict situations. The purpose of this study is to survey a large sample of veterans and other consumers with disabilities who use mobility-assistive technologies to identify priorities for future research and development., Materials and Methods: This survey asked participants to provide opinions on the importance of developing various mobility-assistive technologies and to rank the importance of certain technologies. Participants were also asked to provide open-ended comments and suggestions., Results: A total of 1,022 individuals, including 500 veterans, from 49 states within the USA and Puerto Rico completed the survey. The average age of respondents was 54.3 yr, and they represented both new and experienced users of mobility-assistive technologies. The largest diagnostic group was spinal cord injury (SCI) (N = 491, 48.0%). Several themes on critical areas of research emerged from the open-ended questions, which generated a total of 1,199 comments., Conclusion: This survey revealed several themes for future research and development. Advanced wheelchair design, smart device applications, human-machine interfaces, and assistive robotics and intelligent systems emerged as priorities. Survey results also demonstrated the importance for researchers to understand the effects of policy and cost on translational research and to be involved in educating both consumers and providers. more...

Wheelchair users rely on their wheelchairs for mobility for extended periods of time every day. According to the International Standards Organization 2631-1 standard on human vibration, individuals in a seated position when exposed to whole-body vibrations (WBV) are at risk of injury. This study evaluated vibration exposure during manual and power wheelchair driving over nine sidewalk surfaces and differences in vibration exposure over 3 years. Ten nondisabled subjects were asked to drive a manual wheelchair at 1 m/s and a power wheelchair at 1 m/s and 2 m/s over nine sidewalk surfaces while WBV were measured at the seat and footrest of the wheelchair. At 1 m/s, significant differences existed between surfaces and years at both the seat and the footrest for the manual and power wheelchair users. At 2 m/s, significant differences existed between surfaces and years at the seat and the footrest for power wheelchair users. Our results show that both manual and power wheelchair users may be at risk for secondary injuries from WBV when traveling over certain surfaces. more...

Although airbags measurably reduce the overall risk of injury to adults (including eye injury), and death from motor vehicle accidents, injuries attributed to airbag deployment have been reported. To identify reported cases of ocular trauma related to airbag deployment, a MEDLINE search from 1991 to 2000 was performed. A total of 263 injuries in 101 patients were identified. Patient demographics, details of the accident, specific ocular structures injured, and visual outcomes when available where tabulated and analyzed. The most common of these affect the eyes. Damage to the orbit and virtually every ocular and adnexal structure has been seen. Although most injuries are self-limited and do not significantly compromise vision, some result in severe, permanent visual loss. Most common is damage to anterior structures due to either blunt, contusive forces and/or chemical injury. Posterior segment trauma is less common but generally more visually devastating because of the involvement of the retina or optic nerve. Data are not available to determine whether the wearing of eyeglasses or previous intraocular surgery affects the nature, severity, or outcome of these injuries. Awareness of the spectrum of airbag-associated ocular trauma will help physicians recognize these problems early and optimize their management. Data derived from analyses of these injuries will be critical to the development of safer, more effective devices. more...
