We report on isolation, capture, and subsequent elution for analysis of extracellular vesicles derived from human liposarcoma cell conditioned media, using a multi-layer micro-nanofluidic device operated with tangential flow separation. Our device integrates size-based separation followed by immunoaffinity-based capture of extracellular vesicles in the same device. For liposarcomas, this is the first report on isolating, capturing, and then eluting the extracellular vesicles using a micro-nanofluidic device. The results show a significantly higher yield of the eluted extracellular vesicles (~84%) compared to the current methods of ultracentrifugation (~6%) and ExoQuick-based separations (~16%).The ocular drug discovery arena has undergone a significant improvement in the last few years culminating in the FDA approvals of 8 new drugs. However, despite a large number of drugs, generics, and combination products available, it remains an urgent need to find breakthrough strategies and therapies for tackling ocular diseases. Targeting the adenosinergic system may represent an innovative strategy for discovering new ocular therapeutics. This review focused on the recent advance in the field and described the numerous nucleoside and non-nucleoside modulators of the four adenosine receptors (ARs) used as potential tools or clinical drug candidates.The reflection map introduced by D'Angelo is applied to deduce simpler descriptions of nondegeneracy conditions for sphere maps and to the study of infinitesimal deformations of sphere maps. It is shown that the dimension of the space of infinitesimal deformations of a nondegenerate sphere map is bounded from above by the explicitly computed dimension of the space of infinitesimal deformations of the homogeneous sphere map. Moreover a characterization of the homogeneous sphere map in terms of infinitesimal deformations is provided.
Understanding associations between psychosocial and physical factors among those who experience food insecurity could help design effective food insecurity programs for improved cardiovascular health among low-income populations. We examined differences in psychosocial and physical factors between those who were food secure compared with food insecure among public housing residents.
Data were from the baseline survey of a randomized controlled trial of a weight management intervention in Boston, Massachusetts from 2016-2017. Food insecurity and psychosocial and physical factors, including perceived stress, personal problems, social support, and physical symptoms, were measured via interviewer-administered screeners.
Mean age of the sample (N=102) was 46.5 years (SD=11.9). The majority were Hispanic (67%), female (88%), with ≤high school degree (62%). Nearly half were food insecure (48%). For psychosocial variables, those who were food insecure had higher ratings of perceived stress (adjusted mean difference 3.39, 95% CI2.00,4.79), a higher number of personal problems (adjusted mean difference 1.85, 95% CI 1.19, 2.51), and lower social support (adjusted mean difference -0.70, 95% CI-1.30,-0.11) compared with those who were food secure. For physical variables, those who were food insecure had higher odds of reporting negative physical symptoms (aOR 4.92, 95% CI1.84,13.16).
Among this sample of public housing residents, food insecurity was associated with higher stress, more personal problems, higher experiences of physical symptoms, and lower social support.

This study examined whether health insurance stability was associated with improved type 2 diabetes mellitus (DM) control and reduced racial/ethnic health disparities.
We utilized electronic medical record data (2005-2013) from two large, urban academic health systems with a racially/ethnically diverse patient population to examine insurance coverage, and three DM outcomes (poor diabetes control, A1c ≥8.0%; very poor diabetes control A1c >9.0%; and poor BP control, ≥ 130/80 mm Hg) and one DM management outcome (A1c monitoring). We used generalized estimating equations adjusting for age, sex, comorbidities, site of care, education, and income. Carbohydrate Metabolism modulator Additional analysis examined if insurance stability (stable public or private insurance over the six-month internal) moderates the impact of race/ethnicity on DM outcomes.
Nearly 50% of non-Hispanic (NH) Whites had private insurance coverage, compared with 33.5% of NH Blacks, 31.5% of Asians, and 31.1% of Hispanics. Overall, and within most racial/ ethnic groups, insurance stability was associated with better glycemic control compared with those with insurance switches or always being uninsured, with uninsured NH Blacks having significantly worse BP control. More NH Black and Hispanic patients had poorly controlled (A1c≥8%) and very poorly controlled (A1c>9%) diabetes across all insurance stability types than NH Whites or Asians. The interaction between insurance instability and race/ethnic groups was statistically significant for A1c monitoring and BP control, but not for glycemic control.
Stable insurance coverage was associated with improved DM outcomes for all racial / ethnic groups, but did not eliminate racial ethnic disparities.

The United States is experiencing an opioid overdose crisis accounting for as many as 130 deaths per day. As a result, health care providers are increasingly aware that prescribed opioids can be misused and diverted. Prescription of pain medication, including opioids, can be influenced by how health care providers perceive the trustworthiness of their patients. These perceptions hinge on a multiplicity of characteristics that can include a patient's race, ethnicity, gender, age, and presenting health condition or injury. The purpose of this study was to identify how trauma care providers evaluate and plan hospital discharge pain treatment for patients who survive serious injuries.
Using a semi-structured guide from November 2018 to January 2019, we interviewed 12 providers (physicians, nurse practitioners, physician assistants) who prescribe discharge pain treatment for injured patients at a trauma center in Philadelphia, PA. We used thematic analysis to interpret these data.
Participants identified the importance of determining "true" pain, which was the overarching theme that emerged in analysis. Subthemes included perceptions of the influence of reliable methods for pain assessment, the trustworthiness of their patient population, and the consequences of not getting it right.
Trauma care providers described a range of factors, beyond patient-elicited pain reports, in order to interpret their patients' analgesic needs. These included consideration of both the risks of under treatment and unnecessary suffering, and overtreatment and contribution to opioid overdoses.

We make three key points in this commentary. First, policies that affect our lives and health are developed and implemented every single day, like it or not. These include "small p" policies, such as those at our workplaces that influence whether we have affordable access to healthy food at work, as well as "large P" policies that, for example, determine at a larger level whether our children's schools are required to provide physical education. However, policies interact with context and are likely to have differential effects across different groups based on demographics, socioeconomic status, geography, and culture. We are unlikely to improve health equity if we do not begin to systematically evaluate the ways in which policies can incorporate evidence-based approaches to reducing inequities and to provide structon. Third, development of an explicit policy implementation science agenda focused on health equity is critical. This will include efforts to bridge scientific evidence and policy adoption and implementation, to evaluate policy impact on a range of health equity outcomes, and to examine differential effects of varied policy implementation processes across population groups. We cannot escape the reality that policy influences health and health equity. Policy implementation science can have an important bearing in understanding how policy impacts can be health-promoting and equitable.
To understand barriers and facilitators to the adaptation of programs reflecting changing scientific guidelines for breast/cervical cancer screening, including factors influencing the de-implementation of messaging, program components, or screening practices no longer recommended due to new scientific evidence.
National sample of NWP sites from across the United States.
We conducted a convergent mixed-methods design in partnership with The National Witness Project (NWP), a nationally implemented evidence-based lay health advisor (LHA) program for breast/cervical cancer screening among African American (AA) women. link2 Surveys were conducted among 201 project directors (PDs) and LHAs representing 14 NWP sites; in-depth interviews were conducted among 14 PDs to provide context to findings. Survey data and qualitative interviews were collected concurrently from January 2019-January 2020.
Trust and mistrust were important themes that arose in quantitative and qualitative data. link3 Common concerns about adapting tosidered in implementation science as they 1) have critical implications for shaping health inequities; and 2) help explain and contextualize why new screening guidelines may not be fully embraced in the AA community.
The high prevalence of trauma and its negative impact on health among people living with HIV underscore the need for adopting trauma-informed care (TIC), an evidence-based approach to address trauma and its physical and mental sequelae. However, virtually nothing is known about factors internal and external to the clinical environment that might influence adoption of TIC in HIV primary care clinics.
We conducted a pre-implementation assessment consisting of in-depth interviews with 23 providers, staff, and administrators at a large urban HIV care center serving an un-/under-insured population in the southern United States. We used the Consolidated Framework for Implementation Research (CFIR) to guide qualitative coding to ascertain factors related to TIC adoption.
Inner setting factors perceived as impacting TIC adoption within HIV primary care included relative priority, compatibility, available resources, access to knowledge and information (ie, training), and networks and communications. Relevant outer setting factors included patient needs/resources and cosmopolitanism (ie, connections to external organizations).
