RESUMEN

PURPOSE: The COVID-19 public health emergency (PHE) led to increased mental health (MH) concerns among Medicare beneficiaries while inhibiting their access to MH services (MHS). To help address these problems, the federal government introduced temporary flexibilities permitting broader telehealth use in Medicare. This study compared rural versus urban patterns of change in telemental health (TMH) use among adult MHS users in fee-for-service Medicare from 2019 to 2020, when PHE-related telehealth expansions were enacted. METHODS: In this cross-sectional investigation based on 2019-2020 Medicare claims data, we used chi-square tests, t-tests and adjusted logistic regression to explore how year (pre-PHE vs. PHE), rurality, and beneficiary characteristics were related to TMH use. FINDINGS: From 2019 to 2020, the proportion of MHS users who used TMH rose from 4.8% to 51.9% among rural residents (p < 0.0001) and from 1.1% to 61.3% (p < 0.0001) among urban residents. Across study years, adjusted odds of TMH use grew more than 18-fold for rural MHS users (OR = 18.10, p < 0.001) and nearly 120-fold for their urban counterparts (OR = 119.75, p < 0.001). Among rural MHS users in 2020, adjusted odds of TMH use diminished with increasing age. CONCLUSIONS: TMH mitigated PHE-related barriers to MHS access for rural and urban beneficiaries, but urban residents benefited disproportionately. Among rural beneficiaries, older age was related to lower TMH use. To avoid reinforcing existing MHS access disparities, policies must address factors limiting TMH use among rural beneficiaries, especially those over 75 and those from historically underserved communities.

RESUMEN

BACKGROUND: Trends in the prevalence of hepatitis C virus (HCV) infection among women delivering live births may differ in rural vs. urban areas of the United States, but estimation of trends based on observed counts may lead to unstable estimates in rural counties due to small numbers. OBJECTIVES: The objective of the study was to use small area estimation methods to provide updated county-level prevalence estimates and, for the first time, trends in maternal HCV infection among live births by county-level rurality. METHODS: Cross-sectional natality data from 2016 to 2020 were used to estimate maternal hepatitis C prevalence using hierarchical Bayesian models with spatiotemporal random effects to produce annual county-level estimates of maternal HCV infection and trends over time. Models included a 6-level rural-urban county classification, year, maternal characteristics and county-specific covariates. Data were analysed in 2022. RESULTS: There were 90,764/18,905,314 live births (4.8 per 1000) with HCV infection reported on the birth certificate. Hepatitis C prevalence was higher among rural counties as compared to urban counties. Rural counties had the largest annual increases in maternal hepatitis C prevalence (per 1000 births) from 2016 to 2020 (micropolitan: 0.39; noncore: 0.40), with smaller increases among less densely populated urban counties (medium metro: 0.28; small metro: 0.28) and urban counties (large central metro:0.11; large fringe metro: 0.14). CONCLUSIONS: The prevalence of maternal HCV infection was the highest in rural counties, and rural counties saw the greatest average prevalence increase during 2016-2020. County-level data can help in monitoring rural-urban trends in maternal HCV infection to reduce geographic disparities.

RESUMEN

Importance: Unintended pregnancy is common in the US and is associated with adverse maternal and infant health outcomes; however, estimates of these associations specific to current US populations are lacking. Objective: To evaluate associations of unintended pregnancy with maternal and infant health outcomes during pregnancy and post partum with studies relevant to current clinical practice and public health in the US. Data Sources: Cochrane Central Register of Controlled Trials and Database of Systematic Reviews, PsycINFO, SocINDEX, and MEDLINE databases (January 1, 2000, to June 15, 2022) and manual review of reference lists. Study Selection: Epidemiologic studies relevant to US populations that compared key maternal and infant health outcomes for unintended vs intended pregnancies and met prespecified eligibility criteria were included after investigators' independent dual review of abstracts and full-text articles. Data Extraction and Synthesis: Investigators abstracted data from publications on study methods, participant characteristics, settings, pregnancy intention, comparators, confounders, and outcomes; data were validated by a second investigator. Risk of bias was independently dual rated by investigators using criteria developed by the US Preventive Services Task Force. Results of studies controlling for confounders were combined by using a profile likelihood random-effects model. Main Outcomes and Measures: Prenatal depression, postpartum depression, maternal experience of interpersonal violence, preterm birth, and infant low birth weight. Results: Thirty-six studies (N = 524 522 participants) were included (14 cohort studies rated good or fair quality; 22 cross-sectional studies); 12 studies used large population-based data sources. Compared with intended pregnancy, unintended pregnancy was significantly associated with higher odds of depression during pregnancy (23.3% vs 13.9%; adjusted odds ratio [aOR], 1.59 [95% CI, 1.35-1.92]; I2 = 85.0%; 15 studies [n = 41 054]) and post partum (15.7% vs 9.6%; aOR, 1.51 [95% CI, 1.40-1.70]; I2 = 7.1%; 10 studies [n = 82 673]), interpersonal violence (14.6% vs 5.5%; aOR, 2.22 [95% CI, 1.41-2.91]; I2 = 64.1%; 5 studies [n = 42 306]), preterm birth (9.4% vs 7.7%; aOR, 1.21 [95% CI, 1.12-1.31]; I2 = 1.7%; 10 studies [n = 94 351]), and infant low birth weight (7.3% vs 5.2%; aOR, 1.09 [95% CI, 1.02-1.21]; I2 = 0.0%; 8 studies [n = 87 547]). Results were similar in sensitivity analyses based on controlling for history of depression for prenatal and postpartum depression and on study design and definition of unintended pregnancy for relevant outcomes. Studies provided limited sociodemographic data and measurement of confounders and outcomes varied. Conclusions and Relevance: In this systematic review and meta-analysis of epidemiologic observational studies relevant to US populations, unintended pregnancy, compared with intended pregnancy, was significantly associated with adverse maternal and infant outcomes.

RESUMEN

BACKGROUND: The effectiveness and harms of contraceptive counseling and provision interventions are unclear. PURPOSE: To evaluate evidence of the effectiveness of contraceptive counseling and provision interventions for women to increase use of contraceptives and reduce unintended pregnancy, as well as evidence of their potential harms. DATA SOURCES: English-language searches of Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, PsycINFO, SocINDEX, and MEDLINE (1 January 2000 to 3 February 2022) and reference lists of key studies and systematic reviews. STUDY SELECTION: Randomized controlled trials of interventions providing enhanced contraceptive counseling, contraceptives, or both versus usual care or an active control. DATA EXTRACTION: Dual extraction and quality assessment of studies; results combined using a profile likelihood random-effects model. DATA SYNTHESIS: A total of 38 trials (43 articles [25 472 participants]) met inclusion criteria. Contraceptive use was higher with various counseling interventions (risk ratio [RR], 1.39 [95% CI, 1.16 to 1.72]; I 2 = 85.3%; 10 trials), provision of emergency contraception in advance of use (RR, 2.12 [CI, 1.79 to 2.36]; I 2 = 0.0%; 8 trials), and counseling or provision postpartum (RR, 1.15 [CI, 1.01 to 1.52]; I 2 = 6.6%; 5 trials) or at the time of abortion (RR, 1.19 [CI, 1.09 to 1.32]; I 2 = 0.0%; 5 trials) than with usual care or active controls in multiple clinical settings. Pregnancy rates were generally lower with interventions, although most trials were underpowered and did not distinguish pregnancy intention. Interventions did not increase risk for sexually transmitted infections (STIs) (RR, 1.05 [CI, 0.87 to 1.25]; I 2 = 0.0%; 5 trials) or reduce condom use (RR, 1.03 [CI, 0.94 to 1.13]; I 2 = 0.0%; 6 trials). LIMITATION: Interventions varied; few trials were adequately designed to determine unintended pregnancy outcomes. CONCLUSION: Contraceptive counseling and provision interventions that provide services beyond usual care increase contraceptive use without increasing STIs or reducing condom use. Contraceptive care in clinical practice could be improved by implementing enhanced contraceptive counseling, provision, and follow-up; providing emergency contraception in advance; and delivering contraceptive services immediately postpartum or at the time of abortion.

RESUMEN

BACKGROUND: In rural areas with health professional workforce shortages, telehealth offers an opportunity to address service gaps and meet the health needs of students. Few studies have examined telehealth implementation in rural schools. This study explores facilitators and barriers to the implementation of telehealth programs in rural schools and identifies strategies for successful implementation to inform future school-based telehealth initiatives. METHODS: We conducted semi-structured qualitative interviews with 50 key informants involved in the implementation of telehealth programs funded through the School-Based Telehealth Network Grant Program. Researchers completed a thematic analysis of interview transcripts. RESULTS: The most commonly cited barriers were technology, reimbursement for services, and facilitating acceptance of the telehealth among school staff, clinicians, parents, and students. Key informants identified strategies for facilitating program implementation, including technology training and support, marketing efforts, and integration into existing school processes. CONCLUSIONS: School-based telehealth can augment clinical capacity in areas with clinician shortages. Entities interested in such an approach to care must engage with their school community to ensure successful implementation. For rural, school-based telehealth to gain greater adoption and be sustained, these services must be reimbursable by Medicaid and private insurers.

RESUMEN

INTRODUCTION: Stigma is a barrier to accessing treatment and support services for individuals with substance use disorder. Stigma is negatively associated with completion of treatment for substance use disorder and management of recovery. OBJECTIVE: To learn from individuals in recovery from opioid use disorder in a largely rural area about how their personal experiences of stigma affected their ability to enter into treatment and stay in recovery. METHODS: We conducted ten focus group sessions with established cohorts of individuals in recovery who met regularly as part of recovery programs in central Maine, including two cohorts of postpartum women. Focus groups included 58 participants (33 women and 25 men, age > 18). We conducted a content analysis of focus group transcripts. RESULTS: Study participants identified hospitals, government agencies, and pharmacies as the primary locations where they had stigmatizing experiences. Participants identified pharmacists and pharmacy technicians as the most frequent perpetrators of stigma. Participants identified fear and secrecy as pathways through which stigma negatively affected their recovery. CONCLUSION: Anti-stigma training programs and related efforts conducted in rural areas may benefit from including pharmacists and pharmacy technicians in training activities, and from considering hospital, government agency, and pharmacy settings as venues for anti-stigma interventions.

RESUMEN

INTRODUCTION: The prevalence of hepatitis C virus infection among women delivering live births in the U.S. may be higher in rural areas where county-level estimates may be unreliable. The aim of this study is to model county-level maternal hepatitis C virus infection among deliveries in the U.S. METHODS: In 2020, U.S. natality files (2010-2018) with county-level maternal residence information were used from states that had adopted the 2003 revised U.S. birth certificate, which included a field for hepatitis C virus infection present during pregnancy. Hierarchical Bayesian spatial models with spatiotemporal random effects were applied to produce stable annual county-level estimates of maternal hepatitis C virus infection for years when all states had adopted the revised birth certificate (2016-2018). Models included a 6-Level Urban-Rural County Classification Scheme along with the birth year and county-specific covariates to improve posterior predictions. RESULTS: Among approximately 32 million live births, the overall prevalence of maternal hepatitis C virus infection was 3.5 per 1,000 births (increased from 2.0 in 2010 to 5.0 in 2018). During 2016-2018, posterior predicted median county-level maternal hepatitis C virus infection rates showed that nonurban counties had 3.5-3.8 times higher rates of hepatitis C virus than large central metropolitan counties. The counties in the top 10th percentile for maternal hepatitis C virus rates in 2018 were generally located in Appalachia, in Northern New England, along the northern border in the Upper Midwest, and in New Mexico. CONCLUSIONS: Further implementation of community-level interventions that are effective in reducing maternal hepatitis C virus infection and its subsequent morbidity may help to reduce geographic and rural disparities.

RESUMEN

Introduction. Infections with the respiratory pathogen Mycoplasma pneumoniae are often chronic, recurrent and resistant, persisting after antibiotic treatment. M. pneumoniae grown on glass forms protective biofilms, consistent with a role for biofilms in persistence. These biofilms consist of towers of bacteria interspersed with individual adherent cells.Hypothesis/Gap Statement. A tissue culture model for M. pneumoniae biofilms has not been described or evaluated to address whether growth, development and resistance properties are consistent with persistence in the host. Moreover, it is unclear whether the M. pneumoniae cells in the biofilm towers and individual bacterial cells have distinct roles in disease.Aim. We evaluated the properties of biofilms of M. pneumoniae grown on the immortalized human bronchial epithelial cell line BEAS-2B in relation to persistence in the host. We observed nucleation of biofilm towers and the disposition of individual cells in culture, leading to a model of how tower and individual cells contribute to infection and disease.Methodology. With submerged BEAS-2B cells as a substrate, we evaluated growth and development of M. pneumoniae biofilms using scanning electron microscopy and confocal laser scanning microscopy. We characterized resistance to erythromycin and complement using minimum inhibitory concentration assays and quantification of colony forming units. We monitored biofilm tower formation using time-lapse microscopic analysis of host-cell-free M. pneumoniae cultures.Results. Bacteria grown on host cells underwent similar development to those grown without host cells, including tower formation, rounding and incidence of individual cells outside towers. Erythromycin and complement significantly reduced growth of M. pneumoniae. Towers formed exclusively from pre-existing aggregates of bacteria. We discuss a model of the M. pneumoniae biofilm life cycle in which protective towers derive from pre-existing aggregates, and generate individual cytotoxic cells.Conclusion . M. pneumoniae can form protective biofilms in a tissue culture model, implicating biofilms in chronic infections, with aggregates of M. pneumoniae cells being important for establishing infections.

RESUMEN

PURPOSE: This study assesses trends in telehealth use in Maine-a rural state with comprehensive telehealth policies-across payers, services, and rurality, and identifies barriers and facilitators to the adoption and use of telehealth services. METHODS: Using a mixed-methods approach, researchers analyzed data from Maine's All Payer Claims Database (2008-2016) and key informant interviews with health care organization leaders to examine telehealth use and explore factors impacting telehealth adoption and implementation. FINDINGS: Despite a 14-fold increase in the use of telehealth over the 9-year study period, use remains low-0.28% of individuals used telehealth services in 2016 compared with 0.02% in 2008. Services provided via telehealth varied by rurality; speech language pathology (SLP) was the most common type of service among rural residents, while psychiatric services were most common among urban residents. Medicaid was the primary payer for over 70% of telehealth claims in both rural and urban areas of the state, driving the increase of telehealth claims over time. Issues challenging organizations seeking to deploy telehealth included provider resistance, staff turnover, provider shortages, and lack of broadband. Key informants identified inadequate and inconsistent reimbursement as barriers to comprehensive, systematic billing for telehealth services, resulting in underrepresentation of telehealth services in claims data. CONCLUSIONS: Claims covered by Medicaid account for much of the observed expansion of telehealth use in Maine. Telehealth appears to be improving access to behavioral health and SLP services. Provider shortages, broadband, and Medicare and commercial coverage policies limit the use of telehealth services in rural areas.

RESUMEN

PURPOSE: Few studies have examined telehealth use among rural Medicaid beneficiaries. This study produced a descriptive overview of telehealth use in 2011, including the prevalence of telehealth use among rural and urban Medicaid beneficiaries, characteristics of telehealth users, types of telehealth services provided, and diagnoses associated with telehealth use. METHODS: Using data from the 2011 Medicaid Analytic eXtract (MAX), we conducted bivariate analyses to test the associations between rurality and prevalence and patterns of telehealth use among Medicaid beneficiaries. FINDINGS: Rural Medicaid beneficiaries were more likely to use telehealth services than their urban counterparts, but absolute rates of telehealth use were low-0.26% of rural nondual Medicaid beneficiaries used telehealth in 2011. Psychotropic medication management was the most prevalent use of telehealth for both rural and urban Medicaid beneficiaries, but the proportion of users who accessed nonbehavioral health services through telehealth was significantly greater as rurality increased. Regardless of telehealth users' residence, mood disorders were the most common reason for obtaining telehealth services. As rurality increased, significantly higher proportions of telehealth users received services to address attention-deficit/hyperactivity disorder (ADHD) and other behavioral health problems usually diagnosed in childhood. CONCLUSIONS: These findings provide a baseline for further policy-relevant investigations including examinations of changes in telehealth use rates in Medicaid since 2011. Reimbursement policies and unique rural service needs may account for the observed differences in rural-urban Medicaid telehealth use rates.

RESUMEN

INTRODUCTION: Active transportation opportunities and infrastructure are an important component of a community's design, livability, and health. Features of the built environment influence active transportation, but objective study of the natural experiment effects of built environment improvements on active transportation is challenging. The purpose of this study was to develop and present a novel method of active transportation research using webcams and crowdsourcing, and to determine if crosswalk enhancement was associated with changes in active transportation rates, including across a variety of weather conditions. METHODS: The 20,529 publicly available webcam images from two street intersections in Washington, DC, USA were used to examine the impact of an improved crosswalk on active transportation. A crowdsource, Amazon Mechanical Turk, annotated image data. Temperature data were collected from the National Oceanic and Atmospheric Administration, and precipitation data were annotated from images by trained research assistants. RESULTS: Summary analyses demonstrated slight, bi-directional differences in the percent of images with pedestrians and bicyclists captured before and after the enhancement of the crosswalks. Chi-square analyses revealed these changes were not significant. In general, pedestrian presence increased in images captured during moderate temperatures compared to images captured during hot or cold temperatures. Chi-square analyses indicated the crosswalk improvement may have encouraged walking and biking in uncomfortable outdoor conditions (P < 0.5). CONCLUSION: The methods employed provide an objective, cost-effective alternative to traditional means of examining the effects of built environment changes on active transportation. The use of webcams to collect active transportation data has applications for community policymakers, planners, and health professionals. Future research will work to validate this method in a variety of settings as well as across different built environment and community policy initiatives.

RESUMEN

Pancratistatin (PST), a natural compound obtained from the Hawaiian spider lily, is known to be specific and selective in inducing apoptosis in multiple cancer cell lines while sparing noncancerous cells and cell lines. Here we report the ability of PST to induce apoptosis specifically in human breast cancer cell lines MCF-7 and Hs-578-T compared to their non cancerous counterparts. In cancer cells PST caused increased levels of reactive oxygen species (ROS), decreased ATP and mitochondrial membrane permeabilization indicating the activation of the mitochondrial pathway of apoptosis. In combination with the anti-estrogen Tamoxifen, PST had a synergic effect. Both compounds caused increased production of ROS when applied to isolated mitochondria from these cancer cell lines supporting the observation that Tamoxifen might work through mechanisms distinct from the canonical estrogen receptor antagonism.
