Abstract
Fast ion phase-space flow, driven by Alfvén eigenmodes (AEs), is measured by an imaging neutral particle analyzer in the DIII-D tokamak. The flow firstly appears near the minimum safety factor at the injection energy of neutral beams, and then moves radially inward and outward by gaining and losing energy, respectively. The flow trajectories in phase space align well with the intersection lines of the constant magnetic moment surfaces and constant E-(ω/n)P_{ζ} surfaces, where E, P_{ζ} are the energy and canonical toroidal momentum of ions; ω and n are angular frequencies and toroidal mode numbers of AEs. It is found that the flow is so destructive that the thermalization of fast ions is no longer observed in regions of strong interaction. The measured phase-space flow is consistent with nonlinear hybrid kinetic-magnetohydrodynamics simulation. Calculations of the relatively narrow phase-space islands reveal that fast ions must transition between different flow trajectories to experience large-scale phase-space transport.

Abstract
BACKGROUND: Despite therapeutic advances for patients with schizophrenia, improving patient outcomes and reducing the cost of care continue to challenge formulary decision makers. OBJECTIVES: To (1) understand the perspectives of formulary decision makers on challenges to optimal schizophrenia population management and (2) identify best practices and recommendations for mitigating these challenges. METHODS: This mixed-methods study, conducted in a double-blind manner, comprised in-depth telephone interviews with formulary decision makers from February through May 2020, and a web-based follow-on survey that was sent to all participants in October 2020. US-based formulary decision makers were recruited if they were directly involved in schizophrenia drug formulary or coverage decision making for national or regional payers, health systems, or behavioral health centers. Formulary decision makers' perceptions of challenges, policies, and programs related to schizophrenia population health management were assessed generally and in the context of the COVID-19 pandemic. RESULTS: 19 formulary decision makers participated in the interviews and 18 (95%) completed the survey. Participants reported a spectrum of patient- and payer-driven challenges in schizophrenia population health management, including medication nonadherence, high pharmacy and medical costs, and frequent hospitalizations and emergency department visits. Participants noted that COVID-19 had worsened all identified challenges, although patient unemployment (mean score of 2.00 on a scale of 1 [made much worse] to 5 [made much better]) and reduced access to psychiatric care (mean score, 2.12) were most negatively affected. The most common strategies implemented in order to improve schizophrenia population health management included case management (89%), telemedicine (83%), care coordination programs (72%), strategies to mitigate barriers to accessing medication (61%), and providing nonmedical services to address social determinants of health (56%). Participants noted that, ideally, all treatments for schizophrenia would be available on their formularies without utilization management policies in place in order to increase accessibility to medication, but cost to the health plans made that difficult. Whereas 61% of respondents believed that long-acting injectable antipsychotics (LAIs) were currently underused in their organizations, only 28% represented organizations with open access policies for LAIs. Participants believed that among patients with schizophrenia, LAIs were most beneficial for those with a history of poor or uncertain adherence to oral medications (mean score of 4.50 on a scale of 1 [not at all beneficial] to 5 [extremely beneficial]) and those with recurring emergency department visits and inpatient stays (mean score, 3.94). Study participants reported slightly increased use of LAIs (mean score of 3.17 on a scale of 1 [negatively impacted] to 5 [positively impacted]) among their patients with schizophrenia in response to the COVID-19 pandemic; 29% of participants reported easing access restrictions for LAIs. CONCLUSIONS: Participants described persisting challenges and various approaches intended to improve schizophrenia population health management. They also recommended strategies to optimize future health management for this population, including expanding programs to address social determinants of health and mitigating barriers to accessing treatment.

Abstract
Abstract
Background
Recurrent pericarditis (RP) patients report that painful, debilitating flares negatively impact their health-related quality of life (HRQoL). RHAPSODY, the Phase 3 trial of rilonacept (IL-1α/IL-1β cytokine trap), included a daily pain diary and patient-reported outcome SF-36v2 to measure HRQoL throughout the trial.
Purpose
The purpose of this research is to evaluate the effect of rilonacept on HRQoL in relation to changes in pain for RP patients who have a recurrence.
Methods
RHAPSODY enrolled 86 patients with acute symptomatic RP to receive weekly rilonacept for a 12-week run-in (RI) period and randomized 61 patients (1:1) to receive placebo (n=31) or continue rilonacept (n=30) for the event-driven randomized-withdrawal (RW) period. Patients on placebo who experienced a qualifying recurrence during RW (return of pericarditis pain and increase in C-reactive protein) were rescued with bailout rilonacept. Patients reported daily pericarditis pain electronically, using a 0–10 numeric rating scale (NRS), and completed the SF-36v2 at study visits prior to clinician interaction. Scores from RI Baseline (BL), RI Week 12 (RW BL), Recurrence visit, and RW up to Week 24 (or end of study; EOS) were evaluated for patients who experienced recurrence in RW. Analyses exclude one patient randomized to placebo who had a recurrence after Week 24 of the RW period.
Results
Analyses focused on the 22 of 30 patients (73%) in the placebo group who experienced a recurrence before Week 24 of RW (median time from RW BL to recurrence: 8.6 weeks). During RI, daily pain scores decreased while on rilonacept (Cohen's effect size [ES] d=−2.0), and SF-36v2 scores improved, with scores at RI BL (Fig. 1 red line) below the general population average of 50 and near or above average at RI Week 12 (Fig. 1 blue line); ES were all large (d>0.8), ranging from 0.917 (Mental Component Summary) to 2.021 (Bodily Pain). At recurrence, pain scores increased (d=6.5; Fig. 2) and SF-36v2 scores were below the population average (Fig. 1 orange line), with largest reductions between RI Week 12 (RW BL) and recurrence for Bodily Pain (−13.4) and Physical Component Summary (−10.6). Following rilonacept bailout, average pain decreased (d=−2.1; Fig. 2), and by RW Week 24/EOS, SF-36v2 scores returned to similar levels as at the end of the RI period (Fig. 1 green line).
Conclusion
Impaired RI BL SF-36v2 scores indicate negative impact of RP on HRQOL in RP patients. While receiving rilonacept, HRQoL scores improved to near or above population averages, in conjunction with patient-reported pain. After discontinuing rilonacept during RW, HRQoL scores worsened at recurrence and improved upon receipt of bail-out rilonacept, similar to pain. These results provide support for the broader benefit of rilonacept treatment beyond pain, when administered on top of conventional therapies and as mono-therapy, providing evidence of its potential to improve HRQoL in this patient population.

Abstract
Abstract
Background
Annually in the United States (US), an estimated 80–90,000 patients are diagnosed with acute pericarditis and 15–30% experience recurrent pericarditis (RP), resulting in increased morbidity and reduced health-related quality of life (HRQoL). Treatment options include non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine. Corticosteroids (CS) are often added to the treatment plan in RP despite CS-associated adverse events and inherent potentiation of recurrence with long-term treatment. A recent Phase 3 clinical trial RHAPSODY (NCT03737110) demonstrated efficacy and safety of rilonacept, an interleukin-1 α and β cytokine trap, in patients with RP. RHAPSODY data helped support FDA approval of the first therapy for RP. With the emergence of this targeted therapy, there is increased interest to learn more about this disease with the goal to better inform treatment and management decisions and improve long-term outcomes.
Purpose
RESONANCE Registry aims to evaluate the natural history of RP by collecting retrospective and prospective, longitudinal physician- and patient-reported outcomes data in real-world clinical practice across the US.
Methods
RP patients with active disease (recurrence within 3 years) will have both retrospective and prospective data collected (Figure 1) for as long as their RP is managed up to 5 years. For patients with inactive disease (no recurrence within 3 years), data collection will be retrospective (Figure 2). Up to 500 patients in the US are planned for enrollment at pediatric and adult medical centers, with the potential for expansion to European sites. Additionally, patients will be recruited through a novel, internet-based technology platform and screened for eligibility at a “decentralized” trial site. The registry will include variables obtained from health records, including baseline characteristics and medical history, as well as patient reported outcome (PRO) measures collected every 3 months. The RESONANCE protocol is designed to include a broad population of pediatric and adult patients, regardless of etiology or treatment course, including patients treated with rilonacept. Data will be analyzed to understand disease heterogeneity, variability in treatment and management, and impact on HRQoL. The protocol and Case Report Forms (CRFs) were developed in collaboration with physicians, patients, and patient advocates.
Conclusions
Registries utilize real-world data to fill knowledge gaps in the management of less common diseases such as RP. The RESONANCE Registry is the first RP registry designed to collect data across a broad range of patients regardless of treatment. The registry will also serve as a connection point for physicians to further educate and empower patients with information about their disease. In addition, PRO data may enable greater insights into the understanding of the burden of RP from the patient's perspective.

Abstract
Abstract
Background
Low QRS amplitude (QRSa), QRS fractionation (QRSf) and longer QRS duration (QRSd) are markers of myocardial fibrosis and inflammation in non-ischemic cardiomyopathy (NICM).
Objective
To determine if reduction of inflammation with treatment of cardiac sarcoidosis (CS) may reverse these 12 lead ECG parameter changes.
Methods
21 patients (pts) with CS and VT ablation with a positive baseline positron emission tomographic (PET 1) scan were studied. All pts received prednisone ≥40 mg for 4 to 8 weeks followed by a taper and maintenance with methotrexate ± low-dose prednisone, <10 mg/day, until clinically stable and resolution of inflammation on PET 2 one year after initial. In addition, pts with low LV ejection fraction (13/21) received guideline directed medical therapy for heart failure. Pts at 1yr with positive PET2 (9) were compared to those with negative PET2 (12). Baseline and 1yr 12-lead ECGs were analyzed for QRSd, ≥2QRSf contiguous leads and QRSa in the limb leads.
Results
Pts in PET2(+) vs PET2(−) groups has similar gender (men 89% vs 100%, p=0.42), age (57±8 vs 56±10 years, p=0.8) and LV ejection fraction (41±11 vs 46±11, p=0.31). Baseline 12-lead ECGs showed similar QRSd, ≥2QRSf contiguous leads and QRSa for PET2(+) vs PET2(−); P all >0.15 (Table 1). At 1 yr there was a lower prevalence of ≥2QRSf contiguous leads and strong trend for shorter QRS duration and larger QRSa in lead DI if PET2(−) vs PET2(+). 4 pts demonstrated loss of QRSf 2 contiguous leads and/or increase in QRSa in DI by at least 0.15 mV from baseline if PET2(−) and none if PET2(+).
Conclusions
In pts with CS and VT, reversal of inflammation may result in a greater QRSa and reduction in QRSf. An increase in QRSa in lead 1 by >0.15mV and/or loss of QRSf identifies a clear positive response to treatment and negative PET at 1 year.

Abstract
OBJECTIVE To estimate the prevalence, incidence and economic burden of schizophrenia among Medicaid beneficiaries. METHODS Annual prevalence and incidence of schizophrenia among adult Medicaid beneficiaries were estimated during 2012-2017, by state and across six states (IA, KS, MS, MO, NJ and WI). The pooled estimate of the economic burden of schizophrenia was obtained during 1998Q1-2018Q1 across six states; adults with ≥2 diagnoses of schizophrenia were matched 1:1 to schizophrenia-free controls. The last observed schizophrenia diagnosis (schizophrenia cohort) or the last service claim (control cohort) with ≥12 months of continuous Medicaid enrollment before/after it defined the index date. Healthcare resource utilization (HRU) and costs ($2018 USD) incurred 12 months post-index were compared between cohorts. The economic burden of schizophrenia was also evaluated among young adults (18-34 years). RESULTS Annual prevalence of schizophrenia ranged between 2.30% and 2.71% and annual incidence between 0.31% and 0.39% during 2012-2016. In 2017, only states with the highest incidence and prevalence rates (KS, MS, MO) had data, resulting in higher prevalence (4.01%) and incidence (0.52%). For the economic burden, adults with schizophrenia (N = 158,763) had higher HRU and incurred $14,087 higher healthcare costs versus controls (mean: $28,644 vs. $14,557), driven by $4677 higher long-term care costs (all p < .001). Young adults with schizophrenia incurred $14,945 higher healthcare costs versus controls, driven by $3473 higher inpatient costs (p < 0.001). CONCLUSIONS Annual prevalence and incidence of schizophrenia varied by state but remained stable over time. Adults with schizophrenia incurred greater HRU and costs relative to adults without schizophrenia; the burden appeared comparable among young adults.

Abstract
BACKGROUND: Patients with schizophrenia struggle with disease relapses and uncontrolled symptoms, which can either result in or be a result of non-adherence to antipsychotics (APs). The economic burden of such patients is hypothesized to be substantial. OBJECTIVE: To evaluate the economic burden of recently relapsed schizophrenia or of uncontrolled symptoms of schizophrenia with non-adherence to APs in Medicaid beneficiaries. METHODS: Adults with ≥ 2 schizophrenia diagnoses and controls without schizophrenia were identified in Medicaid data (1997Q1-2018Q1) from Iowa, Kansas, Mississippi, Missouri, New Jersey, and Wisconsin. The index date was the last observed schizophrenia diagnosis (cohort with schizophrenia) or the last service claim (control cohort) with ≥ 12 months of continuous Medicaid enrollment before and after it. Cohorts were matched 1:1 using propensity scores. After matching, two subgroups were identified among adults with schizophrenia: (1) patients with schizophrenia and a recent relapse (≥ 1 schizophrenia-related inpatient or emergency department claim ≤ 60 days before or on the index date) and (2) patients with uncontrolled symptoms of schizophrenia (≥ 2 schizophrenia-related hospitalizations) and non-adherence to APs (proportion of days covered < 80%) in the 12-month pre-index period. Previously matched controls were then subset to patients in each subgroup and their matched pairs without schizophrenia, thus maintaining the 1:1 matching ratio. Healthcare resource utilization (HRU) and costs ($2018 USD) in the 12-month post-index (observation) period were compared between matched pairs using adjusted regression models. RESULTS: Among 158,763 patients with schizophrenia, 18,771 (11.8%) had a recent relapse (mean age 50.5 years; 48.6% female, 51.4% male) and 13,697 (8.6%) were not adherent to APs and had uncontrolled symptoms of schizophrenia (mean age 47.1 years; 48.0% female, 52.0% male). During the observation period, patients with recently relapsed schizophrenia and those non-adherent to APs with uncontrolled symptoms of schizophrenia had significantly higher HRU relative to their controls without schizophrenia. Patients with recently relapsed schizophrenia had mean total healthcare costs $21,862 higher relative to their controls ($37,424 vs $15,563), driven by $8,486 higher mean long-term care costs (all P < 0.001). Patients non-adherent to APs with uncontrolled symptoms of schizophrenia had adjusted mean total healthcare costs $20,787 higher relative to their controls ($38,337 vs $15,241), driven by $8,019 higher adjusted mean inpatient costs (all P < 0.001). Additional total healthcare costs incurred by patients with recently relapsed schizophrenia and those of patients non-adherent to APs with uncontrolled symptoms of schizophrenia exceeded by 55.2% and 47.6%, respectively, incremental total healthcare costs incurred by all patients with schizophrenia ($14,087). CONCLUSIONS: Patients with recently relapsed schizophrenia and those non-adherent to AP therapy with uncontrolled symptoms of schizophrenia incurred higher HRU and costs relative to patients without schizophrenia. Additional healthcare costs of these subgroups of patients with schizophrenia appeared higher than in the overall population with schizophrenia.

Abstract
The COVID-19 pandemic and response measures, including lockdowns and the reorientation of health services, have disrupted essential health services for other diseases, including TB, HIV and malaria. For TB, reductions in case detection due to the COVID-19 pandemic are projected to result in increased TB transmission, morbidity and mortality. Active case-finding (ACF) for TB using community-based approaches is a potential strategy to offset reductions in TB detection by obviating the need for patients to seek care at a health facility. A number of approaches can be used to conduct TB ACF safely and screen designated target populations while managing the risks of SARS-CoV-2 transmission for staff, individuals and the community. We present a framework of options for and experience of adapting TB ACF services in response to the challenges of COVID-19 in our programme in Yogyakarta, Indonesia. Key changes have included revised prioritisation of target populations focusing on household contacts, reducing case-finding throughput, implementation of additional infection control measures and precautions, and integration of COVID-19 screening among those being screened for TB. Our approach could inform other programmes seeking to adapt TB ACF services to mitigate the negative impact of COVID-19 on TB case detection.

Abstract
BACKGROUND Schizophrenia is one of 15 major causes of disability worldwide and is responsible for more than USD 150 billion in annual healthcare costs in the United States. Although the burden of schizophrenia as measured by healthcare resource utilization (HRU) is known to be considerable, data generally come from claims databases or healthcare systems/payors representing only a subset of patients, such as Medicare/Medicaid recipients. A broader understanding of HRU across the schizophrenia patient population would help identify underserved groups and inform strategies for improving healthcare delivery. AIMS OF THE STUDY This observational study examined overall HRU and the influence of sociodemographic factors in adult patients with schizophrenia receiving care in a US integrated healthcare system. METHODS A retrospective cohort study was conducted using data from electronic medical records (EMRs). Patients were required to have at least two diagnostic codes for schizophrenia recorded in the EMR within a 12-month period from January 2009 to June 2018, and to have received active care (≥ 1 in-system healthcare visit every six months) for at least 12 months before and after the index date (the earlier of the schizophrenia diagnosis dates). Patients were followed until no longer receiving active care or the end of the study. Patient characteristics were assessed during the 12-month pre-index period, and inpatient, readmission, emergency room (ER), and outpatient visits and antipsychotic prescriptions were described during follow-up. Findings were reported overall and in subgroups by race/ethnicity, age, and sex. RESULTS The study cohort included 2,941 patients (mean age, 48.3 years; 54.5% male, 51.8% black, 45.8% with Medicare). During the follow-up period (mean, 4.6 years), inpatient hospital stays were common, with at least one all-cause, mental health-related, or schizophrenia-related inpatient visit occurring for 48.7%, 47.3%, and 38.8% of patients, respectively. Hospital readmissions within 30 days of an all-cause inpatient visit occurred in 20.4% of patients, with 14.5% of patients readmitted within 30 days of a schizophrenia-related inpatient visit. More than two-thirds of patients had ER visits, and 40.7% had schizophrenia-related ER visits. Only 46.7% of patients with a schizophrenia-related inpatient visit and 58.5% of patients with a mental health-related inpatient visit had a 30-day outpatient follow-up visit. Subgroup analyses revealed that a larger proportion of non-Hispanic black vs non-Hispanic white patients had 30-day outpatient follow-up visits, ER visits, mental health specialist visits, and antipsychotic prescriptions. Moreover, older age was associated with fewer ER and mental health specialist visits and less use of injectable and second-generation antipsychotics, and women were less likely than men to receive antipsychotic therapy, particularly injectable medications. DISCUSSION Patients with schizophrenia receiving care in a US integrated healthcare system had considerable acute HRU and suboptimal rates of routine and follow-up care. Inequities in schizophrenia burden and care were observed in demographic subgroups. IMPLICATIONS FOR HEALTH POLICIES Population health management strategies focusing on efficient resource allocation and improving healthcare quality are needed to reduce the burden of schizophrenia. Differential findings by race/ethnicity, age, and sex indicate the need for optimizing approaches to care in these subgroups.

Abstract
INTRODUCTION Previous evidence demonstrated that patients with schizophrenia consumed substantial healthcare resources in an integrated healthcare system. This study evaluated the impact of initiating once-monthly paliperidone palmitate (PP1M) on healthcare resource utilization (HRU) among patients with schizophrenia treated in a US integrated healthcare system. METHODS This retrospective study used electronic medical records from Atrium Health. Adults with at least two diagnoses of schizophrenia who received an initial PP1M dose between September 2009 and April 2019 (the corresponding date defined the index date) and at least one subsequent dose within 90 days were included. Additionally, patients were required to have received active care (at least one healthcare visit every 6 months) during 12-month pre- and post-index periods and at least one oral antipsychotic prescription during the 12-month pre-index period. Inpatient, emergency room (ER), and outpatient visits were compared over 12-month pre- versus post-index periods within the same cohort using McNemar's and Wilcoxon signed rank tests. Findings were reported for all patients and separately in patients with at least one schizophrenia relapse (schizophrenia-related inpatient or ER visit) during the 12-month pre-index period. RESULTS The study cohort included 210 patients (mean age 34.2 years, 69.5% male, 39.1% had Medicaid). From the 12-month pre- to post-index period, the proportion of patients with visits and mean number of visits reduced for all-cause inpatient (67.6% to 22.4%, 1.2 to 0.4), 30-day readmission (12.4% to 2.4%, 0.2 to 0.1), and ER (68.6% to 45.7%, 2.3 to 1.2) visits, whereas the mean number of outpatient visits increased (8.7 to 11.6) (all P < 0.05). Similar trends were observed for mental health- and schizophrenia-related HRU. The trends in HRU in patients with prior relapse were similar with a higher extent of reduction in inpatient and ER use compared to the overall cohort. CONCLUSION Initiation of PP1M was associated with reduced acute HRU in patients with schizophrenia, indicating potential clinical and economic benefits, especially in patients with prior relapse.

Abstract
OBJECTIVE Antipsychotics with reduced dosing frequency may improve adherence and clinical outcomes for patients with schizophrenia. This study compared treatment patterns, healthcare resource utilization (HRU), and costs between Medicaid beneficiaries with schizophrenia treated with once-monthly paliperidone palmitate (PP1M) and those who transitioned to once-every-three-months paliperidone palmitate (PP3M). METHODS Adults with schizophrenia were identified in a four-state Medicaid database (18 May 2014 to 31 March 2019). The index date was the first PP3M claim (PP3M cohort), or a random PP1M claim (PP1M cohort), following ≥4 months of continuous PP1M treatment among patients with ≥12 months of continuous Medicaid enrollment pre- and post-index. Adherence (proportion of days covered by the index treatment ≥80%), persistence (no gap >90/30 days in the PP3M/PP1M supply), HRU, and costs were compared during the 12-month post-index period between cohorts matched 1:1. RESULTS Among 2374 patients identified, 374 remained in each cohort after matching (mean age 42 years; 30.5% female). Compared to the PP1M cohort, the PP3M cohort was 2.39 times more likely to be adherent (p < .001), 4.63 times more likely to be persistent (p < .001), 33% less likely to have ≥1 hospitalization (p = .011), and 32% less likely to have ≥1 day with home care services (p = .012). Mean annual medical costs were similar between cohorts ($24,970 in the PP3M cohort and $25,736 in the PP1M cohort; p = .854). CONCLUSIONS Medicaid beneficiaries who transitioned to PP3M had higher adherence and persistence, and a reduced likelihood of hospitalization relative to those who continued treatment with PP1M. The results suggest potential clinical value to transitioning eligible patients to PP3M.

Abstract
AIMS To compare adherence, rates of subsequent schizophrenia-related relapses, healthcare resource utilization, and healthcare costs among Medicaid beneficiaries with schizophrenia who initiated once-monthly paliperidone palmitate (PP1M) versus a new oral atypical antipsychotic (OAA) following a recent schizophrenia-related relapse. METHODS Six-state Medicaid data (01/2009-03/2018) were used to identify adults with schizophrenia initiated on PP1M or OAA (index date) within 30 days following a schizophrenia-related relapse (defined as a schizophrenia-related inpatient or emergency room visit). Patients were required to have 12 months of continuous eligibility before (baseline) and after (observation) the index date. Differences in baseline characteristics between PP1M and OAA patients were accounted for using 1:3 matching. RESULTS After matching, characteristics were well-balanced between PP1M (N=208, mean age=39 years, 35.6% female) and OAA patients (N=624, mean age=40 years, 34.6% female). During the 12-month observation period, the mean proportion of days covered for the index medication was 41.2% in the PP1M cohort and 34.7% in the OAA cohort (p=.008). Relative to the OAA cohort, PP1M patients were 33% (p=.013) less likely to have a subsequent relapse and had 29% (p=.004) fewer all-cause inpatient admissions per-patient-per-year (PPPY). Consequently, a significant mean reduction of $6273 in medical costs PPPY (p=.028) was observed, which fully offset the $4770 (p<.001) increase in pharmacy costs PPPY and resulted in a numerical but not statistically significant, decrease in total healthcare costs of $1503 PPPY (p=.621) relative to OAA patients. CONCLUSIONS Among patients with a recent schizophrenia-related relapse, PP1M was associated with a lower risk of subsequent relapse while remaining a cost neutral therapeutic option compared to OAAs.

Abstract
Jupiter's bright persistent polar aurora and Earth's dark polar region indicate that the planets' magnetospheric topologies are very different. High-resolution global simulations show that the reconnection rate at the interface between the interplanetary and jovian magnetic fields is too slow to generate a magnetically open, Earth-like polar cap on the time scale of planetary rotation, resulting in only a small crescent-shaped region of magnetic flux interconnected with the interplanetary magnetic field. Most of the jovian polar cap is threaded by helical magnetic flux that closes within the planetary interior, extends into the outer magnetosphere, and piles up near its dawnside flank where fast differential plasma rotation pulls the field lines sunward. This unusual magnetic topology provides new insights into Jupiter's distinctive auroral morphology.

Abstract
An Imaging Fast Ion D-alpha (IFIDA) diagnostic, characterized by a high optical spatial resolution of ≤2 mm for accurate validation of energetic particle (EP) transport models, has been developed on DIII-D. The diagnostic provides a 2D image in the radial-poloidal plane of the FIDA signal generated by EP emission after charge exchange with an injected neutral beam. A narrow passband filter integrates the FIDA signal in the spectral region of 650-652 nm (blue-shifted FIDA tail), which is mostly generated by co-passing EPs of energies E ≃ 40-80 keV. A beam modulation technique is employed to estimate the active component of the signal, which is then used to compute EP profiles and gradients with a higher accuracy than the standard spectroscopic FIDA diagnostic. The current diagnostic time resolution is ≃3 ms. In this work, the IFIDA diagnostic design is explained and data are compared with the spectroscopic FIDA diagnostic, which shares the same viewing geometry, to assess the improvements in EP profile reconstruction.

Abstract
PURPOSE Patients with schizophrenia often struggle with medication adherence and may benefit from the use of a long-acting injectable antipsychotic, including once-monthly paliperidone palmitate (PP1M), which was previously demonstrated to improve outcomes compared with oral antipsychotics. This study assessed the impact of initiating PP1M therapy on medication adherence, health care resource use (HRU), and costs among Medicaid beneficiaries with schizophrenia and a prior schizophrenia relapse. METHODS A 6-state Medicaid database (from quarter 1 of 2009 to quarter 1 of 2018) was used to identify adults with ≥2 schizophrenia diagnoses who started PP1M therapy on or after January 1, 2010. The index date was the first PP1M claim. Patients had ≥12 months of continuous Medicaid enrollment before and after the index date, ≥1 oral antipsychotic claim in the 12 months before the index date, and ≥1 relapse (proxied as a schizophrenia-related inpatient admission or emergency department [ED] visit) during the 12 months before the index date. Generalized estimating equations were used to compare adherence to antipsychotics (proportion of days covered ≥80%), HRU, and costs (reported in 2018 US dollars) in the 12 months after versus before the index date. Sensitivity analyses were conducted (1) accounting for the minimum and cumulative price inflation Medicaid rebates for pharmacy costs of branded psychiatric medications, (2) among patients with ≥2, ≥3, and ≥4 prior schizophrenia-related inpatient admissions or ED visits, (3) among patients not adherent to antipsychotic treatment before the index date, and (4) among patients switching to PP1M directly from oral risperidone or paliperidone. FINDINGS A total of 1725 patients met the study inclusion criteria (mean age, 39.5 years; 43% female). After versus before the index date, patients were 93% more likely to be adherent to antipsychotic treatment (P < 0.01). The likelihood of inpatient admissions and ED visits decreased by 89% and 49% (all P < 0.01) after initiating PP1M therapy. The number of inpatient days decreased by 31% (P < 0.01) and the number of ED visits by 16% (P = 0.03). Pharmacy costs increased by $514 per-patient-per-month (PPPM), whereas medical costs, driven by inpatient costs, decreased by $391 PPPM (all P < 0.01). Sensitivity analyses yielded similar trends. Notably, total health care cost savings of $231 PPPM were observed after accounting for the cumulative Medicaid rebate for costs of branded psychiatric medications (P < 0.01). IMPLICATIONS In Medicaid beneficiaries with relapsed schizophrenia, transitioning from oral antipsychotics to PP1M was associated with improved adherence to antipsychotics and decreased use of inpatient and ED services. Increased pharmacy costs after the initiation of PP1M were offset by decreased medical costs. After applying the cumulative Medicaid rebate, including the price inflation rebate for costs of branded psychiatric medications, initiation of PP1M therapy resulted in statistically significant health care cost savings.
