One of the theoretical motivations behind the belief that black holes as described by general relativity exist in nature is that it is hard to find matter configurations that mimic their properties, especially their compactness. One of the classic results that goes in this direction is the so-called Buchdahl limit: a bound for the maximum compactness that, under a few assumptions, static fluid spheres in hydrostatic equilibrium can possibly have. We highlight two of the main assumptions that could be violated in physically realistic situations: i) isotropy and ii) an outward-decreasing monotonicity of the density profile, which, as we discuss in detail, can be understood as a form of energy condition. We construct a pair of toy models that exemplify how the Buchdahl limit can be overcome if any of these two assumptions is individually relaxed. In particular, we show that relaxing the monotonicity assumption alone yields a new, less restrictive compactness limit as long as the energy density is not allowed to become negative. If negative energies are permitted, the compactness of these toy models can be as close to the black hole limit as desired. We also discuss how these toy models represent some of the main features of realistic systems, and how they could be extended to find more refined models., Comment: 37 pages, 7 figures

No-hair theorems are uniqueness results constraining the form of the metric of black holes in general relativity. These theorems are typically formulated under idealized assumptions, involving a mixture of local (regularity of the horizon) and global aspects (vacuum spacetime and asymptotic flatness). This limits their applicability to astrophysical scenarios of interest such as binary black holes and accreting systems, as well as their extension to horizonless objects. A previous result due to G\"urlebeck constrains the asymptotic multipolar structure of static spacetimes containing black holes surrounded by matter although not revealing the possible structure of the metric itself. In this work, we disentangle some of these assumptions in the static and axisymmetric case. Specifically: i) we show that only a one-parameter family of black-hole geometries is compatible with a given external gravitational field, ii) we also analyze the case in which the central object is close to forming an event horizon but is still horizonless and show that the deviations from the natural black-hole shape have to die off as one approaches the black hole limit under the physical principle that curvatures are bounded., Comment: 53 pages, 17 figures

Precision measurements of space and time, like those made by the detectors of the Laser Interferometer Gravitational-wave Observatory (LIGO), are often confronted with fundamental limitations imposed by quantum mechanics. The Heisenberg uncertainty principle dictates that the position and momentum of an object cannot both be precisely measured, giving rise to an apparent limitation called the Standard Quantum Limit (SQL). Reducing quantum noise below the SQL in gravitational-wave detectors, where photons are used to continuously measure the positions of freely falling mirrors, has been an active area of research for decades. Here we show how the LIGO A+ upgrade reduced the detectors' quantum noise below the SQL by up to 3 dB while achieving a broadband sensitivity improvement, more than two decades after this possibility was first presented.

Quantum Physics ,General Relativity and Quantum Cosmology ,High Energy Physics - Theory - Abstract
We present a detailed description of a quantum scalar field theory within a flat spacetime confined to a cavity with perfectly reflecting moving boundaries. Moreover, we establish an equivalence between this time-dependent setting and a field theory on an acoustic metric with static Dirichlet boundary conditions. We discuss the classical and quantum aspects of the theory from the latter perspective, accompanied by the introduction of novel numerical techniques designed for the (nonperturbative) computation of particle production attributed to the Dynamical Casimir effect, applicable to arbitrary boundary trajectories. As an illustrative example of these methodologies, we compute the particle production for a massless field in 1+1 dimensions. Notably, our approaches readily extend to encompass scenarios involving massive fields and higher dimensions, Comment: 18 pages, 11 figures; v2: Matches the published version.

Despite the implementation of internet patient portals into the safety net after the introduction of the Affordable Care Act in the United States, little attention has been paid to the process of engaging vulnerable patients into these portals. The portal is a health technology tool that was developed with a mainstream, English-speaking audience in mind. Thus, there are valid concerns that such technologies will actually exacerbate health care disparities, conferring further advantages to the already advantaged. In this paper, we describe a framework for portal engagement (awareness, registration, and use) among safety net patients. We incorporate the experiences in the Los Angeles County Department of Health Services to illustrate important contextual factors for portal outreach in our safety net. Finally, we discuss considerations for moving forward with health technology in the safety net as the next version of patient portals are being developed.

Computer applications to medicine. Medical informatics ,R858-859.7 - Abstract
BackgroundUniversity of California at Los Angeles Health implemented a Best Practice Advisory (BPA) alert for the initiation of an angiotensin-converting enzyme inhibitor (ACEI) or angiotensin-receptor blocker (ARB) for individuals with diabetes. The BPA alert was configured with a “chart closure” hard stop, which demanded a response before closing the chart. ObjectiveThe aim of the study was to evaluate whether the implementation of the BPA was associated with changes in ACEI and ARB prescribing during primary care encounters for patients with diabetes. MethodsWe defined ACEI and ARB prescribing opportunities as primary care encounters in which the patient had a diabetes diagnosis, elevated blood pressure in recent encounters, no active ACEI or ARB prescription, and no contraindications. We used a multivariate logistic regression model to compare the change in the probability of an ACEI or ARB prescription during opportunity encounters before and after BPA implementation in primary care sites that did (n=30) and did not (n=31) implement the BPA. In an additional subgroup analysis, we compared ACEI and ARB prescribing in BPA implementation sites that had also implemented a pharmacist-led medication management program. ResultsWe identified a total of 2438 opportunity encounters across 61 primary care sites. The predicted probability of an ACEI or ARB prescription increased significantly from 11.46% to 22.17% during opportunity encounters in BPA implementation sites after BPA implementation. However, in the subgroup analysis, we only observed a significant improvement in ACEI and ARB prescribing in BPA implementation sites that had also implemented the pharmacist-led program. Overall, the change in the predicted probability of an ACEI or ARB prescription from before to after BPA implementation was significantly greater in BPA implementation sites compared with nonimplementation sites (difference-in-differences of 11.82; P

12. Nonexistence of a parent theory for general relativity and unimodular gravity

General Relativity and Quantum Cosmology ,High Energy Physics - Theory - Abstract
General Relativity (GR) and Unimodular Gravity (UG) provide two equivalent descriptions of gravity that differ in the nature of the cosmological constant. While GR is based on the group of diffeomorphisms that permits the cosmological constant in the action, UG is based on the subgroup of volume-preserving diffeomorphisms together with Weyl transformations which forbid the presence of the cosmological constant. However, the cosmological constant reappears in UG as an integration constant so it arises as a global degree of freedom. Since gauge symmetries are simply redundancies in our description of physical systems, a natural question is whether there exists a "parent theory" with the full diffeomorphisms and Weyl transformations as gauge symmetries so that it reduces to GR and UG respectively by performing suitable (partial) gauge fixings. We will explore this question by introducing Stueckelberg fields both in GR and UG to complete the gauge symmetries in each theory to that of the would-be parent theory. Despite the dynamical equivalence of the two theories, we find that precisely the additional global degree of freedom provided by the cosmological constant in UG obstructs the construction of the parent theory., Comment: 29 pages, no figures, no tables; v2: Matches the published version.

Objective: Examine the impact of a primary care-embedded clinical pharmacist-led intervention (UCMyRx) on hemoglobin A1C and blood pressure control, relative to usual care, among patients with Type 2 diabetes (TD2) and Medicaid, in a large healthcare system. Methods: We used data extracted from the Electronic Health Records system and a Difference-In-Differences study design with a 2:1 propensity-matched comparison group to evaluate the impact of UCMyRx on HbA1c and systolic blood pressure among patients with TD2 and Medicaid, relative to usual care. Results: Having at least one UCMyRx clinical pharmacist visit was associated with a significant reduction in HbA1c; (-.27%, P-value= .03) but no impact on SBP. We do not find differential UCMyRx effects on HbA1c or SBP among the subpopulations with baseline HbA1C ≥9% or SBP ≥150 mmHg, respectively. In Charlson Comorbidity Index (CCI)-stratified analyses we found stronger UCMyRx effects on HbA1C (-.47%, P-value< .02) among the CCI tercile with the lowest comorbidity score (CC1 ≤ 5). Significant UCMyRx effects are only observed among the subpopulation of Medicaid beneficiaries without Medicare (-.35%, P-value= .02). Conclusions: The UCMyRx intervention is a useful strategy for improving HbA1c control among patients with TD2 and Medicaid.

We propose a setting that simulates Hawking radiation from an analogue bouncing geometry, i.e., a collapsing geometry that reverts its collapse after a finite time, in a setup consisting of a coplanar waveguide terminated in superconducting quantum-interference devices at both ends. We demonstrate experimental feasibility of the proposed setup within the current technology. Our analysis illustrates the resilience of Hawking radiation under changes in the physics at energy scales much larger than the temperature, supporting the idea that regular alternatives to black holes would also emit Hawking radiation., Comment: 7 pages, 2 figures

ImportanceAmong patients with type 2 diabetes (T2D), Hispanic individuals are more likely than non-Hispanic White individuals to develop diabetes-related complications.ObjectiveTo examine the association of a pharmacist-led intervention (UCMyRx) with hemoglobin A1c (HbA1c) and systolic blood pressure (SBP) among Hispanic patients with T2D.Design, setting, and participantsThis quality improvement study used electronic health record data and a difference-in-differences study design to evaluate the association of UCMyRx exposure with changes in HbA1c concentration and SBP among Hispanic patients with T2D, relative to usual care, at University of California, Los Angeles primary care clinics between February and April of 2023. The study population included patients with an International Classification of Diseases, Ninth Revision/International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnosis of T2D, self-reporting Hispanic ethnicity, age 18 years or older, with 1 or more visits with a UCMyRx pharmacist (treatment) or 2 or more visits, 2 or more years apart, during the study window (comparison). Additionally, patients had to have the following observations during the study window (March 2, 2013-December 31, 2018): (1) a HbA1c 8% or higher, anywhere between 365 days before and 14 days after the index date (date of the first UCMyRx visit or a randomly generated index date) and a follow-up HbA1c measure within 120 to 365 days after the index date (n = 396) and/or (2) a SBP 140 mm Hg or higher between 365 days before and 14 days after the index date, and a follow-up SBP measure within 120 to 450 days after the index date (n = 795).ExposurePharmacists review laboratory results/vital signs, perform medication reconciliation, and develop personally tailored interventions to address adherence barriers and increase guideline-concordant care.Main outcomes and measuresPre- to post-index date changes in HbA1c and SBP.ResultsOf the 931 unique patients with T2D analyzed, the mean (SD) age was 64 (14.1) years, and 552 (59.3%) were female. In adjusted analyses, having 1 or more UCMyRx visits was associated with a reduction in HbA1c concentration (β = -0.46%; 95% CI, -0.84% to -0.07%) but no change in SBP (β = -1.71 mm Hg; 95% CI, -4.00 to 0.58 mm Hg).Conclusions and relevanceIn this quality improvement study of UCMyRx among Hispanic patients with T2D, a negative association was observed between UCMyRx exposure and HbA1c concentration but not SBP. Pharmacist-led intervention may be a strategy for improving outcomes among Hispanic patients with T2D.

BACKGROUND: US housing policy places a high priority on homeownership, providing large homeowner subsidies that are justified in part by homeownerships purported health benefits. However, studies conducted before, during, and immediately after the 2007-2010 foreclosure crisis found that while homeownership is associated with better health-related outcomes for White households, that association is weaker or non-existent for African-American and Latinx households. It is not known whether those associations persist in the period since the foreclosure crisis changed the US homeownership landscape. OBJECTIVE: To examine the relationship between homeownership and health and whether that relationship differs by race/ethnicity in the period since the foreclosure crisis. DESIGN: We conducted a cross-sectional analysis of 8 waves (2011-2018) of the California Health Interview Survey (n = 143,854, response rate 42.3 to 47.5%). PARTICIPANTS: We included all US citizen respondents ages 18 and older. MAIN MEASURES: The primary predictor variable was housing tenure (homeownership or renting). The primary outcomes were self-rated health, psychological distress, number of health conditions, and delays in receiving necessary medical care and/or medications. KEY RESULTS: Compared to renting, homeownership is associated with lower rates of reporting fair or poor health (OR = 0.86, P

Unimodular Gravity is a theory displaying Weyl rescalings of the metric and transverse (volume-preserving) diffeomorphisms as gauge symmetries, as opposed to the full set of diffeomorphisms displayed by General Relativity. Recently, we presented a systematic comparison of both theories, concluding that both of them are equivalent in everything but the behaviour of the cosmological constant under radiative corrections. A careful study of how Unimodular Gravity can be embedded in the string theory framework has not been provided yet and was not analyzed there in detail. In this article, we provide such an explicit analysis, filling the gap in the literature. We restrict ourselves to the unoriented bosonic string theory in critical dimension for the sake of simplicity, although we argue that no differences are expected for other string theories. Our conclusions are that both a Diff and a WTDiff invariance principle are equally valid for describing the massless excitations of the string spectrum., Comment: 28 pages, no figures; v2: Matches the published version.

General Relativity and Quantum Cosmology ,High Energy Physics - Theory - Abstract
In this work we study diffeomorphism-invariant metric-affine theories of gravity from the point of view of self-interacting field theories on top of Minkowski spacetime (or other background). We revise how standard metric theories couple to their own energy-momentum tensor, and discuss the generalization of these ideas when torsion and nonmetricity are also present. We review the computation of the corresponding currents through the Hilbert and canonical (Noether) prescriptions, emphasizing the potential ambiguities arising from both. We also provide the extension of this consistent self-coupling procedure to the vielbein formalism, so that fermions can be included in the matter sector. In addition, we clarify some subtle issues regarding previous discussions on the self-coupling problem for metric theories, both General Relativity and its higher derivative generalizations. We also suggest a connection between Lovelock theorem and the ambiguities in the bootstrapping procedure arising from those in the definition of conserved currents., Comment: 32 pages, no figures, no tables; v2: Matches the published version.

General Relativity and Quantum Cosmology ,High Energy Physics - Theory - Abstract
Unimodular Gravity is an alternative to General Relativity (GR) which, however, is so closely related to the latter that one can wonder to what extent they are different. The different behavior of the cosmological constant in the semiclassical regimes of both frameworks suggests the possible existence of additional contrasting features. UG and GR are based on two different gauge symmetries: UG is based on transverse diffeomorphisms and Weyl rescalings (WTDiff transformations), whereas GR is based on the full group of diffeomorphisms. This difference is related to the existence of a fiduciary background structure, a fixed volume form, in UG theories. In this work we present an overview as complete as possible of situations and regimes in which one might suspect that some differences between these two theories might arise. This overview contains analyses in the classical, semiclassical, and quantum regimes. When a particular situation is well known we make just a brief description of its status. For situations less analyzed in the literature we provide here more complete analyses. Whereas some of these analyses are sparse through the literature, many of them are new. Apart from the completely different treatment they provide for the cosmological constant problem, our results uncover no further differences between them. We conclude that, to the extent that the technical naturalness of the cosmological constant is regarded as a fundamental open issue in modern physics, UG is preferred over GR since the cosmological constant is technically natural in the former., Comment: 58 pages, no figures; v2: Matches the published version.

Analogue gravity systems offer many insights into gravitational phenomena, both at the classical and at the semiclassical level. The existence of an underlying Minkowskian structure (or Galilean in the non-relativistic limit) in the laboratory has been argued to directly forbid the simulation of geometries with Closed Timelike Curves (CTCs) within analogue systems. We will show that this is not strictly the case. In principle, it is possible to simulate spacetimes with CTCs whenever this does not entail the presence of a chronological horizon separating regions with CTCs from regions that do not have CTCs. We find an Analogue-gravity Chronology protection mechanism very similar in spirit to Hawking's Chronology Protection hypothesis. We identify the universal behaviour of analogue systems near the formation of such horizons and discuss the further implications that this analysis has from an emergent gravity perspective. Furthermore, we build explicit geometries containing CTCs, for instance spacetimes constructed from two warp-drive configurations, that might be useful for future analysis, both from a theoretical and an experimental point of view., Comment: 37 pages, 8 figures; v2: Minor changes introduced to match the published version

General Relativity and Quantum Cosmology - Abstract
One of the main problems that emergent-gravity approaches face is explaining how a system that does not contain gauge symmetries ab initio might develop them effectively in some regime. We review a mechanism introduced by some of the authors for the emergence of gauge symmetries in [JHEP 10 (2016) 084] and discuss how it works for interacting Lorentz-invariant vector field theories as a warm-up exercise for the more convoluted problem of gravity. Then, we apply this mechanism to the emergence of linear diffeomorphisms for the most general Lorentz-invariant linear theory of a two-index symmetric tensor field, which constitutes a generalization of the Fierz-Pauli theory describing linearized gravity. Finally we discuss two results, the well-known Weinberg-Witten theorem and a more recent theorem by Marolf, that are often invoked as no-go theorems for emergent gravity. Our analysis illustrates that, although these results pinpoint some of the particularities of gravity with respect to other gauge theories, they do not constitute an impediment for the emergent gravity program if gauge symmetries (diffeomorphisms) are emergent in the sense discussed in this paper., Comment: 35 pages, 1 figure; Contribution to the Special Issue Analogue Gravitational Dynamics; v2: Minor changes introduced in the text to match the published version

Quantum simulation of lattice gauge theories (LGTs), aiming at tackling non-perturbative particle and condensed matter physics, has recently received a lot of interest and attention, resulting in many theoretical proposals, as well as several experimental implementations. One of the current challenges is to go beyond 1+1 dimensions, where four-body (plaquette) interactions, not contained naturally in quantum simulating devices, appear. In this Letter, we propose a method to obtain them based on a combination of stroboscopic optical atomic control and the non-local photon-mediated interactions appearing in nanophotonic or cavity QED setups. We illustrate the method for a $\mathbb{Z}_{2}$ lattice Gauge theory. We also show how to prepare the ground state and measure Wilson loops using state-of-the-art techniques in atomic physics.

BackgroundElectronic health (eHealth) literacy may affect telehealth uptake, yet few studies have evaluated eHealth literacy in underserved populations.ObjectiveThe objective of this study was to describe technology access and use patterns as well as eHealth literacy levels among English-speaking and LEP patients in a Los Angeles safety net health system.MethodsPatients, aged ≥18 years with a diagnosis of diabetes mellitus and/or hypertension, and their caregivers were recruited from three primary care safety-net clinics in Los Angeles County (California) between June - July 2017. Participants' electronic health literacy was assessed by the eHealth Literacy Scale (eHEALS); participants were also asked about technology access and use. We examined these measures in English-speaking and limited English proficient (LEP) Spanish-speaking patients.ResultsA total of 71 participants (62 patients and 9 caregivers) completed the questionnaire. The mean age of the respondents was 56 years old. More than half of participants used a phone that could connect to the Internet (67%). The mean score for 10 eHEALS items was in the moderate range (26/50 points). There was no difference in mean eHEALS between language groups. However, 47% of Spanish-speaking participants "agreed/strongly agreed" that they knew how to use the Internet to answer their health questions, compared to 68% of English-speaking participants (P

General Relativity and Quantum Cosmology ,Quantum Physics - Abstract
Taking the principles of quantum mechanics as they stand and applying them to gravity, leads to the conclusion that one might be able to generate superpositions of spacetimes, at least formally. We analyze such a possibility from an analogue gravity perspective. We present an analogue toy model consisting of a Bose-Einstein condensate in a double-well potential and identify the states that could potentially be interpreted as superposition of effective spacetimes. These states are unstable and the source of instability from a microscopic point of view can be related to the absence of a well-defined causal structure in the effective geometric description. We explore the consequences of these instabilities and argue that they resonate with Penrose's ideas about the decay that superpositions of states with sufficiently different gravitational fields associated should experience., Comment: 13 pages, 2 figures, shortened version that matches the published one

General Relativity and Quantum Cosmology ,High Energy Physics - Theory - Abstract
We derive a master equation for the reduced density matrix of a uniformly accelerating quantum detector in arbitrary dimensions, generically coupled to a field initially in its vacuum state, and analyze its late time regime. We find that such density matrix asymptotically reaches a Gibbs state. The particularities of its evolution towards this state are encoded in the response function, which depends on the dimension, the properties of the fields, and the specific coupling to them. We also compare this situation with the thermalization of a static detector immersed in a thermal field state, pinpointing the differences between both scenarios. In particular, we analyze the role of the response function and its effect on the evolution of the detector towards equilibrium. Furthermore, we explore the consequences of the well-known statistics inversion of the response function of an Unruh-DeWitt detector linearly coupled to a free scalar field in odd spacetime dimensions. This allows us to specify in which sense accelerated detectors in Minkowski vacuum behave as static detectors in a thermal bath and in which sense they do not., Comment: 9 pages, no figures; v2: Minor changes introduced in the text to match the published version

High Energy Physics - Theory ,General Relativity and Quantum Cosmology - Abstract
Gauge symmetries remove unphysical states and guarantee that field theories are free from the pathologies associated with these states. In this work we find a set of general conditions that guarantee the removal of unphysical states in field theories describing interacting vector fields. These conditions are obtained through the extension of a mechanism for the emergence of gauge symmetries proposed in a previous article [C. Barcel\'o et al. JHEP 10 (2016) 084] in order to account for non-Abelian gauge symmetries, and are the following: low-energy Lorentz invariance, emergence of massless vector fields describable by an action quadratic in those fields and their derivatives, and self-coupling to a conserved current associated with specific rigid symmetries. Using a bootstrapping procedure, we prove that these conditions are equivalent to the emergence of gauge symmetries and, therefore, guarantee that any theory satisfying them must be equivalent to a Yang-Mills theory at low energies., Comment: 15 pages, no figures; v2: Added minor changes in text to match published version

Physics - Instrumentation and Detectors ,Astrophysics - Instrumentation and Methods for Astrophysics - Abstract
Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nano-meter scale thermo-elastic deformations and substrate lenses from these micron-scale absorbers significantly reduces the sensitivity of the interferometer directly though a reduction in the power-recycling gain and indirect interactions with the feedback control system. We review the expected surface deformation from point absorbers and provide a pedagogical description of the impact on power build-up in second generation gravitational wave detectors (dual-recycled Fabry-Perot Michelson interferometers). This analysis predicts that the power-dependent reduction in interferometer performance will significantly degrade maximum stored power by up to 50% and hence, limit GW sensitivity, but suggests system wide corrections that can be implemented in current and future GW detectors. This is particularly pressing given that future GW detectors call for an order of magnitude more stored power than currently used in Advanced LIGO in Observing Run 3. We briefly review strategies to mitigate the effects of point absorbers in current and future GW wave detectors to maximize the success of these enterprises., Comment: 49 pages, 16 figures. -V2: typographical errors in equations B9 and B10 were corrected (stray exponent of "h" was removed).

Moreno, Gerardo and Scaletta, Michael
- Abstract
In August 2016, Illinois Senate Bill 100 (SB 100) restricted the use of zero tolerance disciplinary practices within public schools when addressing student behavior. In efforts to make school discipline less exclusionary and more effective, SB 100 mandated educators exhaust all means of interventions prior to suspending or expelling a student. Additionally, SB 100 recommended faculty professional development on effective classroom management, which is critical considering the majority of exclusionary discipline cases resulted from referrals by classroom educators for subjective deportment concerns and not from student possession of contraband. Using an online survey instrument, a sample of licensed educators in northeastern Illinois were asked to self-rate their preparedness in classroom management and indicate their awareness of zero tolerance policies. Results demonstrated significant difference of self-rated preparedness between general and special educators when addressing classroom deportment behaviors, while there was no difference in more intense behaviors (e.g., verbal threats, possession of contraband). Discussion on results and suggestions for future research are offered.

ObjectivePatients with multiple medical conditions and complex social issues are at risk for high utilization and poor outcomes. The Connecting Provider to Home program deployed teams of a social worker and a community health worker (CHW) to support patients with social issues and access to primary care. Our objectives were to examine the impact of the program on utilization and satisfaction with care among older adults with complex social and medical issues.DesignRetrospective quasi-experimental observational study with matched comparator group.SettingCommunity-based program in Southern California.ParticipantsFour hundred twenty community dwelling adults.InterventionCommunity-based healthcare program delivered by a social worker and CHW team for older adults with complex medical and social needs.MeasurementsAcute hospitalization and emergency department (ED) visits in the 12 months preceding and following enrollment in the pilot program. A "difference-in-difference" analysis using a matched comparator group was conducted. Comparator group data of patients receiving usual care were obtained. Surveys were conducted to assess patient satisfaction and experiences with the program.ResultsThe mean age of patients was 74 years, and the program demonstrated statistically significant reductions in acute hospitalizations and ED use compared with 700 comparator patients. Pre/post-acute hospitalizations and ED visits were reduced in the intervention group. The average per patient per year reduction in acute hospitalizations was -0.66, whereas the average per patient reduction in ED use was -0.57. Patients enrolled in the program reported high levels of satisfaction and rated the program favorably.ConclusionsA care model with a social worker and CHW can be linked to primary care to address patient social needs and potentially reduce utilization of healthcare services and enhance patient experiences with care.

BackgroundPharmacists are effective at improving control of cardiovascular risk factors, but it less clear whether these improvements translate into less emergency department (ED) use and fewer hospitalizations. The UCMyRx program embed pharmacists in primary care.ObjectiveThe objective of this study was to examine if the integration of pharmacists into primary care was associated with lower ED and hospital use for patients with diabetes.DesignThis was a quasi-experimental study with a comparator group.SubjectsThe analytic sample included patients with diabetes with uncontrolled cardiovascular risk factors (A1C >9%, blood pressure >140/90 mm Hg, low-density lipoprotein-cholesterol >130 mg/dL) who had 1 or more visits in either a UCMyRx (648 patients, 14 practices) or usual care practice (1944 patients, 14 practices).MeasuresOur outcomes were ED and hospitalization rates as measured before and after the consultations between UCMyRx and usual care. Our predictor variable was the pharmacist consultation. Poisson generalized estimating equations model was used to estimate the adjusted predicted change in utilization before and after the pharmacist consultation. The Average Treatment Effect on the Treated was estimated.ResultsIn models adjusted, the adjusted mean predicted number of emergency department visits/month during the year before the consultation was 0.09 among UCMyRx patients. During the year after initiating the care with the pharmacists, this rate decreased to an adjusted mean monthly rate of 0.07, with an Average Treatment Effect on the Treated=0.021 (P=0.035), a predicted reduction of 21% in emergency department visits associated with the clinical pharmacist consults. There was a nonsignificant predicted 3.2% reduction in hospitalizations over time for patients in the UCMyRx program.ConclusionClinical pharmacists are an important addition to clinical care teams in primary care practices and significantly decreased utilization of the ED among patients with poorly controlled diabetes.

Background/objectivesMedication discrepancies and adverse drug events are common following hospital discharge. This study evaluates whether a collaboration between community-based health coaches and primary care-based pharmacists was associated with a reduction in inpatient utilization following hospitalization.DesignRetrospective cohort study using propensity score matching.SettingUrban academic medical center and surrounding community.ParticipantsIntervention patients (n = 494) were adults aged 65 and older admitted to the University of California, Los Angeles (UCLA) Ronald Reagan Medical Center during the study period and who met study inclusion criteria. A matched-control group was composed of patients with similar demographic and clinical characteristics who were admitted to the study site during the study period but who received usual care (n = 2,470). A greedy algorithm approach was used to conduct the propensity score match.InterventionFollowing acute hospitalization, a health coach conducted a home visit and transmitted all medication-related information to a pharmacist based in a primary care practice. The pharmacist compared this information with the patient's electronic medical record medication list and consulted with the patient's primary care provider to optimize medication management.MeasurementsThirty-day readmissions (primary outcome), 60- and 90-day readmissions, and 30-day emergency department (ED) visits (secondary outcomes) to UCLA Health.ResultsAmong 494 patients who received the intervention, 307 (62.1%) were female with a mean age of 83.0 years (interquartile range [IQR] = 76-90 years). Among 2,470 matched-control patients, 1,541 (62.4%) were female with a mean age of 82.7 years (IQR = 74.9-89.5 years). For the propensity score match, standardized mean differences were below .1 for 23 of 25 variables, indicating good balance. Patients who received this intervention had a significantly lower predicted probability of being readmitted within 30 days compared with matched-control patients (10.6%; 95% confidence interval [CI] = 7.9-13.2) vs 21.4%; 95% CI = 19.8-23.0; P value < .001).ConclusionA home visit conducted by a health coach combined with a medication review by a primary care-based pharmacist may prevent subsequent inpatient utilization.

- Abstract
The role of technology in special education has increased over the last 20 years. Expedited by the introduction of Apple iPad and its implementation of touch-based input, the perception of technology has grown from a functional role for students with disabilities to a bridge in accessing general education curriculum. However, quality adoption of new technology within the classroom relies heavily on professional development of the special educator. This paper offers a discussion on the expansion of technology in special education, various attributes associated with quality educator training on technology, and the results of a five-year investigation on the formal training of special educators using iPad tablets. Results indicated longitudinal training focused on active learner experiences had a significant effect on the likelihood of special educator iPad tablet adoption and the resulting implementation in the classroom. Recommendations on educator professional training on iPad tablets follows results.

Recent gravitational-wave observations from the LIGO and Virgo observatories have brought a sense of great excitement to scientists and citizens the world over. Since September 2015,10 binary black hole coalescences and one binary neutron star coalescence have been observed. They have provided remarkable, revolutionary insight into the "gravitational Universe" and have greatly extended the field of multi-messenger astronomy. At present, Advanced LIGO can see binary black hole coalescences out to redshift 0.6 and binary neutron star coalescences to redshift 0.05. This probes only a very small fraction of the volume of the observable Universe. However, current technologies can be extended to construct "$3^\mathrm{rd}$ Generation" (3G) gravitational-wave observatories that would extend our reach to the very edge of the observable Universe. The event rates over such a large volume would be in the hundreds of thousands per year (i.e.tens per hour). Such 3G detectors would have a 10-fold improvement in strain sensitivity over the current generation of instruments, yielding signal-to-noise ratios of 1000 for events like those already seen. Several concepts are being studied for which engineering studies and reliable cost estimates will be developed in the next 5 years., Comment: For the 2020 Astro decadal

BACKGROUND: Patient activation is associated with better outcomes in chronic conditions. OBJECTIVE: We evaluated the psychometric properties of the 12-item Altarum Consumer Engagement™ Measure (ACE-12) in patients with prediabetes. PARTICIPANTS: ACE-12 was administered to patients in the Prediabetes Informed Decisions and Education Study. MAIN MEASURES: We conducted an exploratory factor analysis followed by confirmatory factor analytic models. We evaluated item response categories using item characteristic curves. Construct validity was assessed by examining correlations of the ACE-12 scales with education, depressive symptoms, self-rated health, hemoglobin A1c, body mass index, and weight loss. KEY RESULTS: Participants (n = 515) had a median age of 58; 56% were female; 17% Hispanic; 54% were non-White. The scree plot and Tucker and Lewis reliability coefficient (0.95) suggested three factors similar to the original scales. One item loaded on the navigation rather than the informed choice scale. Ordinal alpha coefficients for the original scales were commitment (0.75); informed choice (0.71); and navigation (0.54). ICCs indicated that one or more of the response categories for 5 of the 12 items were never most likely to be selected. Patients with lower education were less activated on the commitment (r = - 0.124, p = 0.004), choice (r = - 0.085, p = 0.009), and overall score (r = - 0.042, p = 0.011). Patients with depressive symptoms had lower commitment (r = - 0.313, p ≤ 0.001) and overall scores (r = - 0.172, p = 0.012). Patients with poorer health scored lower on the Commitment (r = - 0.308, p ≤ 0.001), Navigation (r = - 0.137, p ≤ 0.001), and overall score (r = - 0.279, p ≤ 0.001). CONCLUSION: The analyses provide some support for the psychometric properties of the ACE-12 in prediabetic patients. Future research evaluating this tool among patients with other chronic conditions are needed to determine whether Q1 (I spend a lot of time learning about health) should remain in the informed choice or be included in the navigation scale. Additional items may be needed to yield acceptable reliability for the navigation scale.

BackgroundBlack individuals with type 2 diabetes suffer disproportionate morbidity and mortality relative to whites with type 2 diabetes, irrespective of health insurance coverage.ObjectiveExamine the impact of a primary care-embedded clinical pharmacist-led intervention (UCMyRx) on cardiovascular risk factor control among blacks with type 2 diabetes in a large healthcare system.DesignWe used data extracted from the electronic health records (EHR) system and a difference-in-differences study design with a propensity-matched comparison group to evaluate the impact of UCMyRx on HbA1c and systolic blood pressure (SBP) among black patients with type 2 diabetes, relative to usual care.ParticipantsIndividuals with type 2 diabetes identified as either black or African American in the EHR that were ≥ 18 years of age that had the following observations during the study window (03/02/2013-12/31/18: (1) HbA1C ≥ 8%, at least once, anywhere between 365 days before and 14 days after the UCMyRx visit and a follow-up HbA1c measure within 120 to 365 days after the visit and/or (2) SBP ≥ 140 mmHg at least once between 365 days before and 14 days after the UCMyRx visit that had a follow-up SBP measure within 120 to 450 days after the visit.InterventionUCMyRx pharmacists review labs and vital signs, perform medication reconciliation, use a standardized survey to assess barriers to medication adherence, and develop tailored interventions to improve medication adherence.Main measuresChange in HbA1c and change in SBP from before to after the first UCMyRx visit.Key resultsHaving at least one visit with a UCMyRx clinical pharmacist was associated with a significant reduction in HbA1c (- 0.4%, p value = .01); however, there was no significant impact on SBP (- .051 mmHg, p value = 0.74).ConclusionsThe UCMyRx intervention is a useful strategy for improving HbA1c control among blacks with type 2 diabetes.
