RESUMEN

BACKGROUND: Numerous US patients seek the hospital emergency department (ED) for behavioral health care. Community Health Centers (CHCs) offer a potential channel for redirecting many to a more patient-centered, lower cost setting. OBJECTIVE: The aim of this study was to identify unique market areas serviced by CHCs and to examine whether CHCs are effective in offsetting behavioral health ED visits. RESEARCH DESIGN: We identified CHC-year specific service areas using patient origin zip codes. We then estimated random effects models applied to 42 federally qualified CHCs operating in New York State during 2013-2020. The dependent variables were numbers of ED mental health (substance use disorder) visits per capita in a CHC's service area, drawn from HCUP State Emergency Department Databases. Key explanatory variables measured CHC number of mental health (substance use disorder) visits, number of unique mental health (substance use disorder) patients, and mental health (substance use disorder) intensity, obtained from the HRSA Uniform Data System. RESULTS: Controlling for population, we observed small negative effects of CHC behavioral health integration in explaining ED behavioral health utilization. Measures of mental health utilization in CHCs were associated with 1.3%-9.3% fewer mental health emergency department visits per capita in Community Health Centers' service areas. Measures of substance use disorder utilization in Community Health Centers were associated with 1.3%-3.0% fewer emergency department visits per capita. CONCLUSION: Results suggest that behavioral health integration in CHCs may reduce reliance on hospital EDs, but that policymakers explore more avenues for regional coordination strategies that align services between CHCs and local hospitals.

RESUMEN

Policy Points The 340B Drug Pricing Program accounts for roughly 1 out of every 100 dollars spent in the $4.3 trillion US health care industry. Decisions affecting the program will have wide-ranging consequences throughout the US safety net. Our scoping review provides a roadmap of the questions being asked about the 340B program and an initial synthesis of the answers. The highest-quality evidence indicates that nonprofit, disproportionate share hospitals may be using the 340B program in margin-motivated ways, with inconsistent evidence for increased safety net engagement; however, this finding is not consistent across other hospital types and public health clinics, which face different incentive structures and reporting requirements. CONTEXT: Despite remarkable growth and relevance of the 340B Drug Pricing Program to current health care practice and policy debate, academic literature examining 340B has lagged. The objectives of this scoping review were to summarize i) common research questions published about 340B, ii) what is empirically known about 340B and its implications, and iii) remaining knowledge gaps, all organized in a way that is informative to practitioners, researchers, and decision makers. METHODS: We conducted a scoping review of the peer-reviewed, empirical 340B literature (database inception to March 2023). We categorized studies by suitability of their design for internal validity, type of covered entity studied, and motivation-by-scope category. FINDINGS: The final yield included 44 peer-reviewed, empirical studies published between 2003 and 2023. We identified 15 frequently asked research questions in the literature, across 6 categories of inquiry-motivation (margin or mission) and scope (external, covered entity, and care delivery interface). Literature with greatest internal validity leaned toward evidence of margin-motivated behavior at the external environment and covered entity levels, with inconsistent findings supporting mission-motivated behavior at these levels; this was particularly the case among participating disproportionate share hospitals (DSHs). However, included case studies were unanimous in demonstrating positive effects of the 340B program for carrying out a provider's safety net mission. CONCLUSIONS: In our scoping review of the 340B program, the highest-quality evidence indicates nonprofit, DSHs may be using the 340B program in margin-motivated ways, with inconsistent evidence for increased safety net engagement; however, this finding is not consistent across other hospital types and public health clinics, which face different incentive structures and reporting requirements. Future studies should examine heterogeneity by covered entity types (i.e., hospitals vs. public health clinics), characteristics, and time period of 340B enrollment. Our findings provide additional context to current health policy discussion regarding the 340B program.

RESUMEN

INTRODUCTION: A disproportionate share of Federally Qualified Health Center (FQHC) users have a behavioral health condition, but there exists limited research examining changes in behavioral health provision in FQHCs. The objectives of this study were to describe how the provision of behavioral health services by FQHCs to the population of people with behavioral health conditions has changed over time in the US, how these trends varied across states, and whether the proportion of total delivered services that are behavioral health services has changed within FQHCs over time. METHODS: Descriptive analysis using the Uniform Data System and Global Burden of Disease Datasets from years 2012 to 2019. RESULTS: From 2012 to 2019, FQHC behavioral health visits per 1,000 population with any behavioral health condition grew 103%, with a 26-fold difference in average rates across states during the study period. Annual behavioral health visits per patient increased from 3.2 to 2012 to 3.4 in 2019. From 2012 to 2019, the number of behavioral health visits per 1,000 FQHC patients grew by 51%, whereas the rate of asthma visits declined by 14%, heart disease visits declined by 4%, and hypertension and diabetes related visits remained stable (changing < 1% for both). DISCUSSION/CONCLUSION: Behavioral health visit growth at FQHCs outpaced national prevalence of behavioral health conditions. This growth was driven by FQHCs serving an increasing number of patients with behavioral health conditions, without sacrificing the frequency of visits for individual patients with behavioral health conditions.

RESUMEN

MicroRNAs (miRNAs) are crucial for normal embryonic stem (ES) cell self-renewal and cellular differentiation, but how miRNA gene expression is controlled by the key transcriptional regulators of ES cells has not been established. We describe here the transcriptional regulatory circuitry of ES cells that incorporates protein-coding and miRNA genes based on high-resolution ChIP-seq data, systematic identification of miRNA promoters, and quantitative sequencing of short transcripts in multiple cell types. We find that the key ES cell transcription factors are associated with promoters for miRNAs that are preferentially expressed in ES cells and with promoters for a set of silent miRNA genes. This silent set of miRNA genes is co-occupied by Polycomb group proteins in ES cells and shows tissue-specific expression in differentiated cells. These data reveal how key ES cell transcription factors promote the ES cell miRNA expression program and integrate miRNAs into the regulatory circuitry controlling ES cell identity.

RESUMEN

Infectious disease is a major concern for both wild and captive primate populations. Primate sanctuaries in Africa provide critical protection to thousands of wild-born, orphan primates confiscated from the bushmeat and pet trades. However, uncertainty about the infectious agents these individuals potentially harbor has important implications for their individual care and long-term conservation strategies. We used metagenomic next-generation sequencing to identify viruses in blood samples from chimpanzees (Pan troglodytes) in three sanctuaries in West, Central, and East Africa. Our goal was to evaluate whether viruses of human origin or other "atypical" or unknown viruses might infect these chimpanzees. We identified viruses from eight families: Anelloviridae, Flaviviridae, Genomoviridae, Hepadnaviridae, Parvoviridae, Picobirnaviridae, Picornaviridae, and Rhabdoviridae. The majority (15/26) of viruses identified were members of the family Anelloviridae and represent the genera Alphatorquevirus (torque teno viruses) and Betatorquevirus (torque teno mini viruses), which are common in chimpanzees and apathogenic. Of the remaining 11 viruses, 9 were typical constituents of the chimpanzee virome that have been identified in previous studies and are also thought to be apathogenic. One virus, a novel tibrovirus (Rhabdoviridae: Tibrovirus) is related to Bas-Congo virus, which was originally thought to be a human pathogen but is currently thought to be apathogenic, incidental, and vector-borne. The only virus associated with disease was rhinovirus C (Picornaviridae: Enterovirus) infecting one chimpanzee subsequent to an outbreak of respiratory illness at that sanctuary. Our results suggest that the blood-borne virome of African sanctuary chimpanzees does not differ appreciably from that of their wild counterparts, and that persistent infection with exogenous viruses may be less common than often assumed.

RESUMEN

OBJECTIVE: To examine the influence of habitus on women's health behavior regarding breastfeeding and subsequent COVID-19 vaccination. DESIGN: A qualitative descriptive design, guided by Pierre Bourdieu's concept of habitus. SAMPLE: Eighteen women who were postpartum, breastfeeding, and vaccinated against COVID- 19 either during pregnancy or while breastfeeding postpartum. MEASURES: Individual semi-structured interviews. RESULTS: Two major themes shaped participants' habitus: health-focused knowledge, and attitudes and beliefs. Attitudes and beliefs included five subthemes: (1) exposure/acceptance/expectations from family, (2) community acceptance of breastfeeding and COVID-19 vaccination, (3) socioeconomic status, (4) easily accessed support, and (5) outside experiences and exposure. DISCUSSION: An individual's habitus impacts one's knowledge, attitudes, and beliefs and interacts with past behaviors when discussing options for infant feeding and health promoting behaviors such as vaccinations. A better understanding of how health care providers assess and utilize habitus in clinical management is needed.

RESUMEN

OBJECTIVES: To evaluate temporal changes in pediatric emergency department (ED) visits for mental health problems in Massachusetts based on diagnoses and patient characteristics and to assess trends in all-cause pediatric ED visits. STUDY DESIGN: This statewide population-based retrospective cohort study used the Massachusetts All-Payer Claims Database, which includes almost all Massachusetts residents. The study sample consisted of residents aged <21 years who were enrolled in a health plan between 2013 and 2017. Using multivariate regression, we examined temporal trends in mental health-related and all-cause ED visits in 2013-2017, with person-quarter as the unit of analysis; we also estimated differential trends by sociodemographic and diagnostic subgroups. The outcomes were number of mental health-related (any diagnosis, plus 14 individual diagnoses) and all-cause ED visits/1000 patients/quarter. RESULTS: Of the 967 590 Massachusetts residents in our study (representing 14.8 million person-quarters), the mean age was 8.1 years, 48% were female, and 57% had Medicaid coverage. For this population, mental health-related (any) and all-cause ED visits decreased from 2013 to 2017 (P < .001). Persons aged 18-21 years experienced the largest declines in mental health-related (63.0% decrease) and all-cause (60.9% decrease) ED visits. Although mental health-related ED visits declined across most diagnostic subgroups, ED visits related to autism spectrum disorder-related and suicide-related diagnoses increased by 108% and 44%, respectively. CONCLUSIONS: Overall rates of pediatric ED visits with mental health diagnoses in Massachusetts declined from 2013 to 2017, although ED visits with autism- and suicide-related diagnoses increased. Massachusetts' policies and care delivery models aimed at pediatric mental health may hold promise, although there are important opportunities for improvement.

RESUMEN

BACKGROUND: Since COVID-19 first appeared in the United States (US) in January 2020, US states have pursued a wide range of policies to mitigate the spread of the virus and its economic ramifications. Without unified federal guidance, states have been the front lines of the policy response. MAIN TEXT: We created the COVID-19 US State Policy (CUSP) database ( https://statepolicies.com/ ) to document the dates and components of economic relief and public health measures issued at the state level in response to the COVID-19 pandemic. Documented interventions included school and business closures, face mask mandates, directives on vaccine eligibility, eviction moratoria, and expanded unemployment insurance benefits. By providing continually updated information, CUSP was designed to inform rapid-response, policy-relevant research in the context of the COVID-19 pandemic and has been widely used to investigate the impact of state policies on population health and health equity. This paper introduces the CUSP database and highlights how it is already informing the COVID-19 pandemic response in the US. CONCLUSION: CUSP is the most comprehensive publicly available policy database of health, social, and economic policies in response to the COVID-19 pandemic in the US. CUSP documents widespread variation in state policy decisions and implementation dates across the US and serves as a freely available and valuable resource to policymakers and researchers.

RESUMEN

OBJECTIVE: To estimate the effect of patient-centered medical home (PCMH) participation on cost and utilization of care for patients in Rhode Island's statewide, multipayer PCMH program, which serves over one-third of the state population. DATA SOURCES/STUDY SETTING: 2009-2014 claims data from all payers in Rhode Island, representing >743,000 unique patients. STUDY DESIGN: A propensity score-matched difference-in-differences framework was used to separately estimate the effect of the PCMH on 3 patient cohorts, which were defined by their intervention start dates and amounts of implementation time. Outcomes included patient costs (total, inpatient, outpatient, professional, pharmacy) and utilization [emergency department (ED) visits, preventable ED visits, inpatient admissions, preventable inpatient admissions, all-cause 30-day readmissions]. Interaction effects were estimated to assess heterogeneity among clinical risk groups and payers. PRINCIPAL FINDINGS: There was no evidence of a PCMH effect on total costs, though we observed evidence of an increase in the odds of PCMH patients having outpatient and professional costs, and in one cohort, a decrease in inpatient costs for those with an inpatient visit. We also observed evidence of reduced ED visits, preventable ED visits, and inpatient admissions for PCMH patients. While subgroup effects varied by cohort and measure, high-risk patients often experienced the largest reductions in ED visits. CONCLUSIONS: All PCMH cohorts experienced statistically significant reductions in some types of utilization in as little as 1.25 years. Reductions were greatest for measures included in the PCMH contractual agreement. While PCMH programs may not expect cost savings in the short-term, costs could potentially be reduced in the longer-term through avoided ED and inpatient expenses.

RESUMEN

BACKGROUND: To monitor progress towards eliminating health disparities, community health centers have reported on hypertension control, diabetes control, and birthweight by race and ethnicity since 2008. OBJECTIVE: To evaluate racial/ethnic time trends in quality outcomes in health centers and to assess both within- and between-center disparities in outcomes. DESIGN AND SAMPLE: Using 2009-2014 data from all US health centers (n = 1047 centers, serving 19.6 million patients/year), we evaluated racial/ethnic time trends in quality outcomes for health centers and assessed within- and between-center disparities. MAIN MEASURES: Percentage of patients achieving control of blood pressure < 140/90 mmHg among hypertensive persons, control of glycosylated hemoglobin ≤ 9.0% among diabetic persons, and birthweight ≥ 2500 g. All outcomes were reported by race/ethnicity. KEY RESULTS: There was no evidence of improved outcomes among racial/ethnic subgroups from 2009 to 2014, though electronic health record adoption, medical recognition, and insurance coverage rates increased substantially. Two exceptions were increased rates of normal birthweight for black patients (87.0% to 88.8%, or 0.3 percentage points/year, p = 0.02) and decreased rates of diabetes control for white patients (74.2% to 69.5%, or -1.0 percentage points/year, p < 0.01). Within centers, the largest racial/ethnic disparities in 2009 were white/black disparities in hypertension control (8.7 percentage points, 95% CI 7.4-10.1), white/black disparities in diabetes control (3.4 percentage points, 95% CI 2.0-4.7), and white/Hispanic disparities in diabetes control (4.4 percentage points, 95% CI 2.8-6.0). All disparities remained statistically unchanged from 2009 to 2014. White patients were more likely to be seen at a health center in the top performance quintile compared with black and Hispanic patients (p < 0.001). CONCLUSIONS: Though quality outcomes in health centers continued to compare favorably to other care settings, we found no evidence of improved quality or reduced disparities in diabetes control, hypertension control, or birthweight from 2009 to 2014. Within- and between-center racial/ethnic disparities in quality were evident, and both should be targeted in future interventions.

RESUMEN

BACKGROUND: Prior studies have reported that community health centers perform as well as other sites of care, despite serving more vulnerable patient populations. However, there is little prior study of geographic variation in quality outcomes and disparities in outcomes in this setting. Quantifying geographic variation is important so as to target quality improvement efforts and funding and to learn from states where total quality is highest and racial/ethnic disparities are lowest. OBJECTIVES: To estimate between-state variation in hypertension, diabetes, and pregnancy outcomes and racial/ethnic disparities in these outcomes for health center patients. METHODS: Using data on all US health centers from 2010 to 2014 (N=1047 health centers/year, or 21.2 million patients in 2014), we used linear regression models to estimate adjusted quality outcomes and racial/ethnic disparities in quality outcomes by state for hypertension control, diabetes control, and normal birthweight. RESULTS: We found wide variation in both outcomes and racial/ethnic disparities in outcomes between states for patients seen at health centers. For instance, between states, the mean proportion of patients with hypertension control ranged from 58% to 70% for white patients, from 49% to 64% for black patients, and from 53% to 74% for Hispanic patients (P<0.001). Racial/ethnic disparities in outcomes ranged from negative or nonsignificant in some states to positive in others. CONCLUSIONS: Wide variation in health center patient outcomes and disparities in outcomes is observed between states. This variation suggests that policymakers should target funding and interventions to underperforming states, and identify determinants of high quality in higher performing states.

RESUMEN

Nations in the 21st century face a complex mix of environmental and social challenges, as highlighted by the on-going Sustainable Development Goals process. The "planetary boundaries" concept [Rockström J, et al. (2009) Nature 461(7263):472-475], and its extension through the addition of social well-being indicators to create a framework for "safe and just" inclusive sustainable development [Raworth K (2012) Nature Climate Change 2(4):225-226], have received considerable attention in science and policy circles. As the chief aim of this framework is to influence public policy, and this happens largely at the national level, we assess whether it can be used at the national scale, using South Africa as a test case. We developed a decision-based methodology for downscaling the framework and created a national "barometer" for South Africa, combining 20 indicators and boundaries for environmental stress and social deprivation. We find that it is possible to maintain the original design and concept of the framework while making it meaningful in the national context, raising new questions and identifying priority areas for action. Our results show that South Africa has exceeded its environmental boundaries for biodiversity loss, marine harvesting, freshwater use, and climate change, and social deprivation is most severe in the areas of safety, income, and employment. Trends since 1994 show improvement in nearly all social indicators, but progression toward or over boundaries for most environmental indicators. The barometer shows that achieving inclusive sustainable development in South Africa requires national and global action on multiple fronts, and careful consideration of the interplay between different environmental domains and development strategies.

RESUMEN

Platelet rich plasma (PRP) was tested as a potential therapy for androgenetic alopecia (AGA) through two different clinical protocols in which one population (18 participants) received half-head treatment with autologous non-activated PRP (A-PRP) produced by CPunT Preparation System (Biomed Device, Modena, Italy) and the other half-head with placebo, and a second separated population in which all participants (n = 6, 3 participants per group) received treatment with calcium-activated PRP (AA-PRP) produced from one of two different PRP collection devices (Regen Blood Cell Therapy or Arthrex Angel System). For the A-PRP study, three treatments were administered over 30-day intervals. Trichoscan analysis of patients, three months post-treatment, showed a clinical improvement in the number of hairs in the target area (36 ± 3 hairs) and in total hair density (65±  5 hair cm2), whereas negligible improvements in hair count (1.1±  1.4 hairs) and density (1.9 ± 10.2 hair cm2) were seen in the region of the scalp that received placebo. Microscopic evaluation conducted two weeks after treatment showed also an increase in epidermal thickness, Ki67+ keratinocytes, and in the number of follicles. The AA-PRP treatment groups received a singular set of injections, and six months after the treatments were administered, notable differences in clinical outcomes were obtained from the two PRP collection devices (+90 ± 6 hair cm2 versus -73 ± 30 hair cm2 hair densities, Regen versus Arthrex). Growth factor concentrations in AA-PRP prepared from the two collection devices did not differ significantly upon calcium activation.

RESUMEN

Cyclin D1 belongs to the core cell cycle machinery, and it is frequently overexpressed in human cancers. The full repertoire of cyclin D1 functions in normal development and oncogenesis is unclear at present. Here we developed Flag- and haemagglutinin-tagged cyclin D1 knock-in mouse strains that allowed a high-throughput mass spectrometry approach to search for cyclin D1-binding proteins in different mouse organs. In addition to cell cycle partners, we observed several proteins involved in transcription. Genome-wide location analyses (chromatin immunoprecipitation coupled to DNA microarray; ChIP-chip) showed that during mouse development cyclin D1 occupies promoters of abundantly expressed genes. In particular, we found that in developing mouse retinas-an organ that critically requires cyclin D1 function-cyclin D1 binds the upstream regulatory region of the Notch1 gene, where it serves to recruit CREB binding protein (CBP) histone acetyltransferase. Genetic ablation of cyclin D1 resulted in decreased CBP recruitment, decreased histone acetylation of the Notch1 promoter region, and led to decreased levels of the Notch1 transcript and protein in cyclin D1-null (Ccnd1(-/-)) retinas. Transduction of an activated allele of Notch1 into Ccnd1(-/-) retinas increased proliferation of retinal progenitor cells, indicating that upregulation of Notch1 signalling alleviates the phenotype of cyclin D1-deficiency. These studies show that in addition to its well-established cell cycle roles, cyclin D1 has an in vivo transcriptional function in mouse development. Our approach, which we term 'genetic-proteomic', can be used to study the in vivo function of essentially any protein.

RESUMEN

OBJECTIVES: To examine whether community health centers (CHCs) are effective in offsetting mental health emergency department (ED) visits. DATA SOURCES AND STUDY SETTING: The HRSA Uniform Data System and the HCUP State ED Databases for Florida patients during 2012-2019. STUDY DESIGN: We identified CHC-year-specific service areas using patient origin zip codes. We then estimated panel data models for number of ED mental health visits per capita in a CHC's service area. Models measured CHC mental health utilization as number of visits, unique patients, and intensity (visits per patient). PRINCIPAL FINDINGS: CHC mental health utilization increased approximately 100% during 2012-2019. Increased CHC mental health provision was associated with small reductions in ED mental health utilization. An annual increase of 1000 CHC mental health care visits (5%) was associated with 0.44% fewer ED mental health care visits (p = 0.153), and an increase of 1000 CHC mental health care patients (15%) with 1.9% fewer ED mental health care visits (p = 0.123). An increase of 1 annual mental health visit per patient was associated with 16% fewer ED mental health care visits (p = 0.011). CONCLUSIONS: Results suggest that mental health provision in CHCs may reduce reliance on hospital EDs, albeit minimally. Policies that promote alignment of services between CHCs and local hospitals may accelerate this effect.

RESUMEN

OBJECTIVE: To describe the national rate of social risk factor screening adoption among federally qualified health centers (FQHCs), examine organizational factors associated with social risk screening adoption, and identify barriers to utilizing a standardized screening tool in 2020. DATA SOURCE: 2020 Uniform Data System, a 100% sample of all US FQHCs (N = 1375). STUDY DESIGN: We used multivariable linear probability models to assess the association between social risk screening adoption and key FQHC characteristics. We used descriptive statistics to describe variations in screening tool types and barriers to utilizing standardized tools. We thematically categorized open-ended responses about tools and barriers. DATA COLLECTION: None. PRINCIPAL FINDINGS: In 2020, 68.9% of FQHCs screened patients for any social risk factors. Characteristics associated with a greater likelihood of screening adoption included having high proportions of patients best served in a language other than English (18.8 percentage point [PP] increase, 95% CI: 6.0, 31.6) and being larger in size (10.3 PP increase, 95% CI: 0.7, 20.0). Having higher proportions of uninsured patients (14.2 PP decrease, 95% CI: -25.5, -0.3) and participating in Medicaid-managed care contracts (7.3 PP decrease, 95% CI: -14.2, -0.3) were associated with lower screening likelihood. Among screening FQHCs, the Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences (PRAPARE) was the most common tool (47.1%). Among non-screening FQHCs, common barriers to using a standardized tool included lack of staff training to discuss social issues (25.2%), inability to include screening in patient intake (21.7%), and lack of funding for addressing social needs (19.2%). CONCLUSIONS: Though most FQHCs screened for social risk factors in 2020, various barriers have prevented nearly 1 in 3 FQHCs from adopting a screening tool. Policies that provide FQHCs with resources to support training and workflow changes may increase screening uptake and facilitate engagement with other sectors.

RESUMEN

Humans can flexibly use metacognition to monitor their own knowledge and strategically acquire new information when needed. While humans can deploy these skills across a variety of contexts, most evidence for metacognition in animals has focused on simple situations, such as seeking out information about the location of food. Here, we examine the flexibility, breadth, and limits of this skill in chimpanzees. We tested semi-free-ranging chimpanzees on a novel task where they could seek information by standing up to peer into different containers. In Study 1, we tested n = 47 chimpanzees to assess if chimpanzees would spontaneously engage in information-seeking without prior experience, as well as to characterize individual variation in this propensity. We found that many chimpanzees engaged in information-seeking with minimal experience, and that younger chimpanzees and females were more likely to do so. In two subsequent studies, we then further tested chimpanzees who initially showed robust information-seeking on new variations of this task, to disentangle the cognitive processing shaping their behaviors. In Study 2, we examined how a subset of n = 12 chimpanzees applied these skills to seek information about the location versus the identity of rewards, and found that chimpanzees were equally adept at seeking out location and identity information. In Study 3, we examined whether a subset of n = 6 chimpanzees could apply these skills to make more efficacious decisions when faced with uncertainty about reward payoffs. Chimpanzees were able to use information-seeking to resolve risk and choose more optimally when faced with uncertain payoffs, although they often also engaged in information-seeking when it was not strictly necessary. These results identify core features of flexible metacognition that chimpanzees share with humans, as well as constraints that may represent key evolutionary shifts in human cognition.
