Abstract
OBJECTIVE The authors sought to describe out-of-pocket (OOP) costs among beneficiaries with schizophrenia differing in Medicare Part D low-income subsidy (LIS) status. METHODS National 100% Medicare claims were used to identify all adult fee-for-service Medicare Part D beneficiaries with schizophrenia who used antipsychotics in 2019 (N=283,813). Proportions of patients by LIS status, OOP costs per prescription, and annual OOP costs were reported. Results were stratified by type of antipsychotic received (oral antipsychotic [OAP], first-generation long-acting injectable [FGA-LAI], or second-generation long-acting injectable [SGA-LAI]). RESULTS In the final sample, 90.3% of beneficiaries had full LIS status, paying minimal copayments (29.6% institutionalized full LIS, paying $0; 42.2% noninstitutionalized full LIS, ≤100% federal poverty level [FPL], paying $1.25-$3.80; and 18.5% noninstitutionalized full LIS, >100% FPL, paying $3.40-$8.50). Only 0.9% of the sample received partial LIS status, and 8.8% had a non-LIS status. Non-LIS beneficiaries had the highest OOP costs, followed by partial LIS beneficiaries. Before entering catastrophic coverage, median OOP costs per prescription for generic OAPs, brand-name OAPs, FGA-LAIs, and SGA-LAIs were $10.85, $171.97, $26.09, and $394.28, respectively, for non-LIS beneficiaries and $3.69, $105.82, $9.35, and $229.20, respectively, for partial LIS beneficiaries. The annual total OOP costs varied substantially by LIS status (full LIS, $0-$130.79; partial LIS, $458.96; non-LIS, $998.81). CONCLUSIONS Most Medicare beneficiaries with schizophrenia qualified for full LIS and faced minimal OOP costs for both OAPs and LAIs. The remainder (i.e., partial LIS and non-LIS beneficiaries) faced substantial OOP costs, both per prescription and annually, especially for SGA-LAIs.

Abstract
OBJECTIVE To determine the diagnostic accuracy of prenatal ultrasound in detecting coarctation of the aorta (CoA). METHODS An individual participant data meta-analysis was performed to report on the strength of association and diagnostic accuracy of different ultrasound signs in detecting CoA prenatally. MEDLINE, EMBASE and CINAHL were searched for studies published between January 2000 and November 2021. Inclusion criteria were fetuses with suspected isolated CoA, defined as ventricular and/or great vessel disproportion with right dominance on ultrasound assessment. Individual participant-level data were obtained by two leading teams. PRISMA-IPD and PRISMA-DTA guidelines were used for extracting data, and the QUADAS-2 tool was used for assessing quality and applicability. The reference standard was CoA, defined as narrowing of the aortic arch, diagnosed after birth. The most commonly evaluated parameters on ultrasound, both in B-mode and on Doppler, constituted the index test. Summary estimates of sensitivity, specificity, diagnostic odds ratio (DOR) and likelihood ratios were computed using the hierarchical summary receiver-operating-characteristics model. RESULTS The initial search yielded 72 studies, of which 25 met the inclusion criteria. Seventeen studies (640 fetuses) were included. On random-effects logistic regression analysis, tricuspid valve/mitral valve diameter ratio > 1.4 and > 1.6, aortic isthmus/arterial duct diameter ratio < 0.7, hypoplastic aortic arch (all P < 0.001), aortic isthmus diameter Z-score of < -2 in the sagittal (P = 0.003) and three-vessel-and-trachea (P < 0.001) views, pulmonary artery/ascending aorta diameter ratio > 1.4 (P = 0.048) and bidirectional flow at the foramen ovale (P = 0.012) were independently associated with CoA. Redundant foramen ovale was inversely associated with CoA (P = 0.037). Regarding diagnostic accuracy, tricuspid valve/mitral valve diameter ratio > 1.4 had a sensitivity of 72.6% (95% CI, 48.2-88.3%), specificity of 65.4% (95% CI, 46.9-80.2%) and DOR of 5.02 (95% CI, 1.82-13.9). The sensitivity and specificity values were, respectively, 75.0% (95% CI, 61.1-86.0%) and 39.7% (95% CI, 27.0-53.4%) for pulmonary artery/ascending aorta diameter ratio > 1.4, 47.8% (95% CI, 14.6-83.0%) and 87.6% (95% CI, 27.3-99.3%) for aortic isthmus diameter Z-score of < -2 in the sagittal view and 74.1% (95% CI, 58.0-85.6%) and 62.0% (95% CI, 41.6-78.9%) for aortic isthmus diameter Z-score of < -2 in the three-vessel-and-trachea view. Hypoplastic aortic arch had a sensitivity of 70.0% (95% CI, 42.0-88.6%), specificity of 91.3% (95% CI, 78.6-96.8%) and DOR of 24.9 (95% CI, 6.18-100). The diagnostic yield of prenatal ultrasound in detecting CoA did not change significantly when considering multiple categorical parameters. Five of the 11 evaluated continuous parameters were independently associated with CoA (all P < 0.001) but all had low-to-moderate diagnostic yield. CONCLUSIONS Several prenatal ultrasound parameters are associated with an increased risk for postnatal CoA. However, diagnostic accuracy is only moderate, even when combinations of parameters are considered. © 2024 The Authors.

Abstract
Mucoepidermoid carcinoma (MEC) is a common malignancy arising in the parotid gland. The diagnosis of MEC is typically based on its morphological features alone, characteristically containing mucocytes, intermediate cells and epidermoid cells. However, when cystic degeneration is diffuse, it is challenging to distinguish MEC from other benign cystic tumors. This is a case report of a 58-year-old Caucasian man who presented with a parotid mass. H&E sections of the mass reveal multiloculated cysts lined by bland-looking epithelium with only rare papillary architectures. The papillary proliferation contains mucocytes, and epidermoid cells highlighted by the p63 immunohistochemistry study. The diagnosis was confirmed by FISH result of positive MAML2 (11q21) rearrangement. Patient underwent parotidectomy and is disease-free 6 months post-surgery. MEC with cystic degeneration is a common diagnostic pitfall which can mimic many benign lesions in the salivary gland. We present a rare case with MEC with extensive cystic change, its molecular and pathologic findings and review the diagnostic features of MEC, its benign mimickers and useful tools for distinguishing these entities.

Abstract
BACKGROUND Adherence to antipsychotic medication and care discontinuity remain a challenge to healthcare practitioners providing care to patients with schizophrenia. OBJECTIVE This study used real-world data from a US hospital-based, all-payer database to examine clinical quality measures among patients with schizophrenia initiated on a long-acting injectable (LAI) or switched to a new oral antipsychotic medication (OAP) following a hospitalization. METHODS A retrospective cohort study using the PINC AI™ Healthcare Database compared two cohorts of patients with schizophrenia on post-index hospitalization clinical quality and care continuity endpoints. Patients initiated on an LAI (n = 7292) or switched to a new OAP (n = 31,956) during an index hospitalization between April 2017 and April 2020 were included. Propensity score weighting addressed differences in patient, hospital, and clinical characteristics between the two cohorts. RESULTS Patients who initiated an LAI experienced significantly greater adjusted 30-day antipsychotic medication continuation to index therapy, higher rate of 30-day outpatient follow-up care, longer mean time to discontinuation of index therapy, and lower risk of discontinuing their index treatment compared to patients who switched to a new OAP (all p values < 0.001). Probability of 30-day antipsychotic medication continuation was significantly higher for LAI initiators than for patients who switched to a new OAP, even after controlling for patient, clinical, and hospital characteristics (adjusted odds ratio = 1.2, 95% CI 1.1-1.3, p < 0.001). CONCLUSION Patients who initiated an LAI in a hospital setting experienced better clinical quality and care continuity outcomes compared to patients who were switched to a new OAP. These findings may be useful in identifying solutions to help improve the quality of medication management post-hospital discharge among patients with schizophrenia.

Abstract
Air pollution has become a global public health hazard leading to debilitating effects on physical, mental, and emotional health. Management research has just begun to explore the effects of air pollution on employees' work life. Drawing from the transactional theory of stress (Lazarus & Folkman, 1984) and crossover theory (Westman, 2001), we argue that appraisal of air pollution is an important factor that influences leaders and their behavior with subordinates. Specifically, we propose that when leaders appraise severe air pollution, they are more likely to behave abusively toward their subordinates and engage in laissez-faire leadership. We also propose that this relationship is mediated by leaders' experience of somatic complaints and negative affect. We test our model using an experience sampling study in India of leaders and followers who were located in different cities from each other. Overall, our results highlight how air pollution appraisals can harm not only the leader experiencing the pollution but also subordinates of those leaders. In other words, our counterintuitive finding is that subordinates may be harmed by air pollution to which they are not even directly exposed.

Abstract
Classical machine learning and deep learning models for Computer-Aided Diagnosis (CAD) commonly focus on overall classification performance, treating misclassification errors (false negatives and false positives) equally during training. This uniform treatment overlooks the distinct costs associated with each type of error, leading to suboptimal decision-making, particularly in the medical domain where it is important to improve the prediction sensitivity without significantly compromising overall accuracy. This study introduces a novel deep learning-based CAD system that incorporates a cost-sensitive parameter into the activation function. By applying our methodologies to two medical imaging datasets, our proposed study shows statistically significant increases of 3.84% and 5.4% in sensitivity while maintaining overall accuracy for Lung Image Database Consortium (LIDC) and Breast Cancer Histological Database (BreakHis), respectively. Our findings underscore the significance of integrating cost-sensitive parameters into future CAD systems to optimize performance and ultimately reduce costs and improve patient outcomes.

Abstract
Abstract Toxicological studies are essential for developing novel medications in pharmaceutical industries including ayurvedic preparation. Hence, the present study is aimed to evaluate acute and 28-days repeated dose oral toxicity of anti-obesity polyherbal granules (PHG) in Sprague Dawley rats by OECD guidelines No 425 and 407, respectively. In an acute oral toxicity study, a single dose of 2 g/kg PHG was administered to rats and mortality, body weight, and clinical observations were noted for fourteen days. However, in the subacute oral toxicity study, the PHG was administered orally at doses of 0.3, 0.5 and 1 g/kg daily for 28 days to rats. Food intake and body weight were recorded weekly. On the 29th day, rats were sacrificed and subjected to haematological, biochemical, urine, necropsy, and histopathological analysis. In an acute oral toxicity study, no treatment-related, mortality, behavioral changes, and toxicity were found throughout fourteen days. Likewise, in the sub-acute toxicity study, no mortality and toxic effects were found in haematology, biochemical, urine, necropsy and histopathological analysis in rats for 28 days of treatment with PHG. Based on these results, the LD50 of PHG was found to be greater than 2 g/kg and the no-observed-adverse-effect level (NOAEL) of PHG for rats was found to be 0.5 g/kg/day. Thus, anti-obesity polyherbal granules showed a good safety profile in animal studies and can be considered an important agent for the clinical management of obesity.

Abstract
BACKGROUND The open sandwich technique is a reliable alternative to amalgam placement in deep proximal box preparations, where proper isolation and enamel bonding may not be possible. It is often difficult to prepare the box for composite placement without affecting the resin-modified glass ionomer (RMGI) that has been placed in the gingival portion. We hypothesized that RMGI surfaces that are roughened or those that use all steps in the manufacturing bonding protocol, including the priming solution, applied before placing a bonded composite increment, would have greater composite/RMGI shear bond strength. DESIGN AND METHODS Shear bond strengths (SBS) of RMGI tested in the presence and absence of SiC roughening and primer-coating were tested using a fourth-generation dentin bonding agent to composite after thermocycling. Twenty specimens for four test conditions were fabricated and investigated. Data were subjected to a two-way ANOVA and the Holm-Sidak post-hoc test. RESULTS Placing dentin primer on unabraded RMGI provided a statistically significant improvement in SBS, but only modestly. Furthermore, because bond failure consistently occurred within the RMGI itself, none of the surface modifications have a clinically relevant impact on SBS at the RMGI to the composite interface. CONCLUSIONS Clinicians should be aware that they need not avoid RMGI abrasion and do not need to incorporate all components of a fourth-generation bonding system when covering an RMGI sandwich layer with composite.

Abstract
BACKGROUND Maintaining continuity of care after schizophrenia-related hospitalization is challenging for patients and healthcare providers and systems. Prior evidence suggests that second-generation long-acting injectable antipsychotics (SGLAIs) may reduce the risk of treatment nonadherence and readmission versus oral atypical antipsychotics (OAAs). Therefore, quality measures were compared between patients initiated on SGLAIs and OAAs in the United States. METHODS Adults newly initiated on an SGLAI or OAA during a schizophrenia-related inpatient stay were identified in HealthVerity databases (01/2015-12/2020); the index date was the hospital discharge date. Patients had continuous health insurance coverage for pharmacy and medical services for 6 months pre-admission and post-discharge from the inpatient stay and ≥1 pharmacy or medical claim (i.e. treatment as indicated by the observed insurance claims) for an antipsychotic other than the index SGLAI or OAA in the 6 months pre-admission. Antipsychotic use and adherence, and schizophrenia-related readmissions and outpatient visits were compared during the 6-month period post-discharge. Characteristics between cohorts were balanced using inverse probability weights. RESULTS Post-discharge, only 36.9% and 40.7% of weighted SGLAI (N = 466) and OAA (N = 517) patients had ≥1 pharmacy or medical claim for the antipsychotic initiated during the inpatient stay, among whom SGLAI patients were 4.4 times more likely to be adherent to that antipsychotic compared to OAA patients (p < .001). Additionally, SGLAI patients were 2.3 and 3.0 times more likely to have a pharmacy or medical claim for and be adherent to any antipsychotic relative to OAA patients (including index antipsychotic; all p < .001). Within 7 and 30 days post-discharge, 1.7% and 13.0% of SGLAI patients and 4.1% and 12.6% of OAA patients had a readmission. Further, SGLAI patients were 51% more likely to have an outpatient visit compared to OAA patients (p = .044). CONCLUSIONS Less than half of patients initiated on antipsychotics during a schizophrenia-related inpatient stay continued the same treatment post-discharge. However, SGLAI patients were more likely to be adherent to the initiated antipsychotic and to have an outpatient visit, which may suggest improved continuity of care post-discharge relative to OAA patients.

Abstract
BACKGROUND Exercise may improve executive function among people living with all-cause dementia (PWD), but more evidence is needed. The aim of this pilot randomized controlled trial (RCT) is to examine whether exercise plus usual care improves the primary outcome of executive function, and secondary physiological (inflammation, metabolic aging, epigenetics) and behavioral (cognition, psychological health, physical function, and falls) outcomes compared to usual care alone among PWD. METHODS AND STUDY DESIGN The strEngth aNd BaLance exercise on Executive function in people living with Dementia (ENABLED) protocol is a pilot parallel, 6-month assessor-blinded RCT (1:1) in residential care facilities, including n = 21 receiving exercise plus usual care and n = 21 usual care alone [NCT05488951]. We will collect primary (Color-Word Stroop Test) and secondary physiological (inflammation, metabolic aging, epigenetics) and behavioral (cognition, psychological health, physical function, and falls) outcomes at baseline and 6 months. We will obtain falls monthly from medical charts. We will collect physical activity, sedentary behavior, and sleep via wrist-worn accelerometers over 7 days at baseline and 6 months. The physical therapist-led adapted Otago Exercise Program will involve 1-h of strength, balance and walking 3×/week for 6 months in groups of 5-7. We will use generalized linear mixed models to examine differences over time in primary and secondary outcomes between groups and examine potential interactions with sex and race. DISCUSSION This pilot RCT will examine the direct effects and potential underlying physiological mechanisms of exercise on executive function and other behavioral outcomes in PWD, which may have implications for clinical care management.

Abstract
BACKGROUND: The Disease Recovery Evaluation and Modification study (DREaM; NCT02431702) assessed the benefit of initiating paliperidone palmitate (PP), a long-acting injectable antipsychotic, in patients with recent-onset schizophrenia or schizophreniform disorder. OBJECTIVE: To determine whether reductions in psychiatric hospitalizations with early initiation of PP vs oral antipsychotic (OAP) therapy observed in a DREaM post hoc analysis are transportable to a real-world population of patients with recent-onset schizophrenia. METHODS: Patients enrolled in DREaM were randomized to receive OAP or PP for 9 months, after which OAP recipients were re-randomized to receive OAP or PP for another 9 months. We used this design to form treatment arms: OAP-OAP, OAP-PP, and PP-PP. Inclusion/exclusion criteria were used to identify a Medicaid Managed Care (MMC) OAP-treated cohort of 1,000 patients diagnosed with schizophrenia using IBM Truven databases from 2015 to 2019. The MMC cohort was combined with the subset of patients diagnosed with schizophrenia enrolled in DREaM from US sites (N = 45, 43, and 44 for OAP-OAP, OAP-PP, and PP-PP, respectively). Propensity scores for the MMC cohort were estimated using baseline variables identified via double-lasso regression. Estimated propensity scores were used to weight psychiatric hospitalizations in the DREaM OAP-OAP group and compared with observed MMC OAP cohort psychiatric hospitalizations. After the successful calibration of the DREaM OAP-OAP group, similar approaches were taken for the OAP-PP and PP-PP groups to transport DREaM effects to MMC data. RESULTS: Standardized mean differences in baseline covariates between DREaM treatment arms and MMC groups were substantially reduced after calibration. The 18-month cumulative numbers of psychiatric hospitalizations per patient (SE) were 0.83 (0.14) for the MMC cohort, 0.43 (0.14) for the unweighted OAP-OAP, and 0.80 (0.37) for the calibrated OAP-OAP. The difference between the calibrated OAP-OAP and MMC was not statistically significant (difference, 0.03 [95% CI = -0.67 to 0.81]), indicating successful calibration. The mean difference in 18-month cumulative psychiatric hospitalizations relative to the MMC cohort was -0.77 (95% CI = -1.08 to -0.47) for OAP-PP and -0.83 (95% CI = -1.15 to -0.60) for PP-PP. CONCLUSIONS: Our study demonstrates that results from the DREaM OAP-OAP group reflect psychiatric hospitalizations in a real-world population when calibrated using specific baseline characteristics. Transporting the DREaM effects, we find that using OAP-PP and PP-PP treatment strategies for patients with recent-onset schizophrenia in the MMC population could reduce psychiatric hospitalizations compared with the use of OAP. These findings, along with the potential reduction in associated costs, should be considered when assessing the value of PP formulations.

Abstract
Background Life sciences research often turns out to be ineffective. Our aim was to develop a method for mapping repetitive research processes, detecting practice variations, and exploring inefficiencies. Methods Three samples of R&I projects were used: companion diagnostics of cancer treatments, identification of COVID-19 variants, and COVID-19 vaccine development. Major steps involved: defined starting points, desired end points; measurement of transition times and success rates; exploration of variations, and recommendations for improved efficiency. Results Over 50% of CDX developments failed to reach market simultaneously with new drugs. There were significant variations among phases of co-development (Bartlett test P<0.001). Length of time in vaccine development also shows variations (P<0.0001). Similarly, subject participation indicates unexplained variations in trials (Phase I: 489.7 (±461.8); Phase II: 857.3 (±450.1); Phase III: 35402 (±18079). Conclusion Analysis of repetitive research processes can highlight inefficiencies and show ways to improve quality and productivity in life sciences.

Abstract
BACKGROUND No research to date has examined antipsychotic (AP) use, healthcare resource use (HRU), costs, and quality of care among those with schizophrenia in the Medicare program despite it serving as the primary payer for half of individuals with schizophrenia in the US. OBJECTIVES To provide national estimates and assess regional variation in AP treatment utilization, HRU, costs, and quality measures among Medicare beneficiaries with schizophrenia. METHODS Cross-sectional descriptive analysis of 100% Medicare claims data from 2019. The sample included all adult Medicare beneficiaries with continuous fee-for-service coverage and ≥1 inpatient and/or ≥2 outpatient claims with a diagnosis for schizophrenia in 2019. Summary statistics on AP use; HRU and cost; and quality measures were reported at the national, state, and county levels. Regional variation was measured using the coefficient of variation (CoV). RESULTS We identified 314,888 beneficiaries with schizophrenia. About 91% used any AP; 20% used any long-acting injectable antipsychotic (LAI); and 14% used atypical LAIs. About 28% of beneficiaries had ≥1 hospitalization and 47% had ≥1 emergency room (ER) visits, the vast majority of which were related to mental health (MH). Total annual all-cause, MH, and schizophrenia-related costs were $23,662, $15,000 and $12,109, respectively. Among those with hospitalizations, 18.4% and 27.3% had readmission within 7 and 30 days and 56% and 67% had a physician visit and AP fill within 30 days post-discharge, respectively. Overall, 81% of beneficiaries were deemed adherent to their AP medications. Larger interstate variations were observed in LAI use than AP use (CoV: 0.21 vs 0.02). County-level variations were larger than state-level variations for all measures. CONCLUSIONS In this first study examining a national sample of Medicare beneficiaries with schizophrenia, we found low utilization rates of LAIs and high levels of hospital admissions/readmissions and ER visits. State and county-level variations were also found in these measures.

Abstract
INTRODUCTION Long-acting injectable antipsychotic agents have been suggested to improve adherence and patient outcomes in schizophrenia or schizoaffective disorder. The purpose of this study was to assess medication use patterns (i.e., medication adherence, persistence), hospital and emergency department readmissions, and total direct medical costs of Oklahoma Medicaid members with schizophrenia or schizoaffective disorder switching from an oral antipsychotic (OAP) to once-monthly paliperidone palmitate (PP1M) or to another OAP (OAP-switch). METHODS A historical cohort analysis was conducted from 1 January 2016 to 31 December 2020 among adults aged ≥ 18 and ≤ 64 years with schizophrenia or schizoaffective disorder who were previously treated with an OAP. The first claim for PP1M or a new OAP defined the study index date. Members who transitioned from PP1M to 3-month formulation (PP3M) were included (i.e., PP1M/PP3M). Proportion of days covered (PDC), 45-day treatment gaps, 30-day readmissions to hospitals or emergency department, and total direct medical costs were assessed using multivariable, machine-learning least absolute shrinkage, and selection operator (Lasso) regressions controlling for numerous demographic, clinical, mental health, and provider characteristics. RESULTS Among 295 Medicaid members meeting full inclusion criteria, 183 involved PP1M/PP3Ms (44 PP1M cases transitioned to PP3M) and 112 involved an OAP-switch. The multivariable-adjusted odds of readmission were significantly associated with a 45-day treatment gap (p < 0.05) and non-adherence (i.e., PDC < 80%) (p < 0.05). Relative to PP1M/PP3Ms, the multivariable analyses also indicated that OAP-switch was associated with an 18.5% lower PDC, 92.3% higher number of 45-day treatment gaps, and an approximately 90% higher odds of all-cause 30-day readmission (p < 0.05). The adjusted pre- to post-index change in cost was approximately 49% lower for OAP-switches versus PP1M/PP3Ms (p < 0.001), although unadjusted post-index costs did not differ between groups (p = 0.440). CONCLUSION This real-world investigation of adult Medicaid members with schizophrenia or schizoaffective disorder observed improved adherence and persistence with fewer readmissions with PP1M/PP3Ms versus OAP-switches.

Abstract
BACKGROUND: Given relapse frequency early in the course of schizophrenia, recently diagnosed patients may benefit from longacting injectable antipsychotics, which are associated with reduced risk of relapse and hospitalization compared with oral antipsychotics (OAPs). OBJECTIVE: To compare health care resource utilization (HCRU) and costs in patients with recent-onset schizophrenia treated with continuous paliperidone palmitate (PP) or continuous OAP or who switched from OAP to PP. METHODS: In this analysis, we combined the 2 randomized phases of the prospective, open-label Disease Recovery Evaluation and Modification (DREaM) clinical study using the principal stratification method to generate 3 treatment strategies: continuous PP for 18 months (PP-PP), continuous OAP for 18 months (OAP-OAP), and initial OAP switched to PP after 9 months (OAP-PP). HCRU metrics included psychiatric hospitalizations, psychiatric and nonpsychiatric emergency department visits, and ambulatory visits. Costs were analyzed using generalized linear models with inverse-probability weighting based on time-varying probabilities of exposure. Robust SEs were estimated using individual-level clustered bootstrapping. Subgroup analyses were performed by region and prior antipsychotic use (< 6 vs ≥ 6 months). RESULTS: A total of 181 patients were included in the PP-PP (n = 61), OAP-OAP (n = 61), and OAP-PP (n = 59) groups. The majority of patients (73%) were enrolled at study sites in the United States, and 48% had received an antipsychotic for less than 6 months prior to study entry. Baseline characteristics were well balanced, and no significant differences in discontinuation rates were observed across treatment strategies. Compared with OAP-OAP, significantly lower cumulative HCRU and costs were apparent before 9 months in the PP-PP group and after 9 months in the OAP-PP group. The cumulative 18-month effects of PP-PP and OAP-PP vs OAP-OAP on the number of psychiatric hospitalizations were ‒0.28 (95% CI = ‒0.51 to ‒0.08) and ‒0.27 (95% CI = ‒0.50 to 0.04), respectively, and those on cumulative mean per-patient total health care costs (in 2020 USD) were -$2,867 (95% CI = ‒$5,133 to ‒$750) and ‒$2,789 (95% CI = ‒$5,155 to ‒$701), respectively. Subgroup analyses indicated a greater reduction in psychiatric hospitalizations and costs with PP-PP or OAP-PP relative to OAP-OAP in patients with less than 6 vs 6 or more months of prior antipsychotic therapy. CONCLUSIONS: Continuous early use of PP in adults with recentonset schizophrenia significantly reduced psychiatric hospitalizations and associated estimated costs compared with OAP; these effects were particularly notable for patients with a shorter duration of prior antipsychotic use. As this was a post hoc analysis of a study that was not powered for HCRU assessments, future studies calibrating these effects to larger real-world populations will be useful.

Abstract
BACKGROUND Next generation sequencing studies have revealed an ever-increasing number of causes for genetic disorders of central nervous system white matter. A substantial number of disorders are identifiable from their specific pattern of biochemical and/or imaging findings for which single gene testing may be indicated. Beyond this group, the causes of genetic white matter disorders are unclear and a broader approach to genomic testing is recommended. AIM This study aimed to identify the genetic causes for a group of individuals with unclassified white matter disorders with suspected genetic aetiology and highlight the investigations required when the initial testing is non-diagnostic. METHODS Twenty-six individuals from 22 families with unclassified white matter disorders underwent deep phenotyping and genome sequencing performed on trio, or larger, family groups. Functional studies and transcriptomics were used to resolve variants of uncertain significance with potential clinical relevance. RESULTS Causative or candidate variants were identified in 15/22 (68.2%) families. Six of the 15 implicated genes had been previously associated with white matter disease (COL4A1, NDUFV1, SLC17A5, TUBB4A, BOLA3, DARS2). Patients with variants in the latter two presented with an atypical phenotype. The other nine genes had not been specifically associated with white matter disease at the time of diagnosis and included genes associated with monogenic syndromes, developmental disorders, and developmental and epileptic encephalopathies (STAG2, LSS, FIG4, GLS, PMPCA, SPTBN1, AGO2, SCN2A, SCN8A). Consequently, only 46% of the diagnoses would have been made via a current leukodystrophy gene panel test. DISCUSSION These results confirm the importance of broad genomic testing for patients with white matter disorders. The high diagnostic yield reflects the integration of deep phenotyping, whole genome sequencing, trio analysis, functional studies, and transcriptomic analyses. CONCLUSIONS Genetic white matter disorders are genetically and phenotypically heterogeneous. Deep phenotyping together with a range of genomic technologies underpin the identification of causes of unclassified white matter disease. A molecular diagnosis is essential for prognostication, appropriate management, and accurate reproductive counseling.

Abstract
AIMS Provide the first national description across the US of variations in healthcare measures in 2018 among Medicaid beneficiaries with schizophrenia. MATERIALS AND METHODS Adult beneficiaries with ≥2 diagnoses for schizophrenia, and continuous enrollment with consistent geographical data in all of 2018 were identified from Transformed Medicaid Statistical Information System (T-MSIS) Analytic Files (TAF) data for 45 of 50 states. Antipsychotic (AP) utilization rates, including long-acting injectable APs (LAIs), quality metrics, and all-cause healthcare resource utilization and costs for claims submitted to Medicaid were reported nationally and by state. Pearson correlation evaluated associations between LAI utilization and total healthcare costs at state and county levels. RESULTS Across the US 688,437 patients with schizophrenia were identified. The AP utilization rate was 51% (state range: 24-77%), while the LAI utilization rate was 13% (range: 4-26%). The proportion of patients adherent to any AP was 56% (range: 19-73%). Within 30 days post-discharge from an inpatient admission, 22% (range: 8-58%) of patients had an outpatient visit, and 12% (range: 4-48%) had a readmission. The proportion of patients with ≥1 inpatient admission and ≥1 emergency room visit was 34% (range: 19-82%) and 45% (range: 20-70%). Per-patient-per-year total healthcare costs averaged $32,920 (range: $717-$93,972). At the county level, a weak negative correlation was observed between LAI utilization and total healthcare costs. LIMITATIONS This study included Medicaid beneficiaries enrolled with pharmacy and medical benefits, including beneficiaries dually eligible for Medicare; results cannot be generalized to the overall schizophrenia population or those with other payer coverage. CONCLUSIONS In 2018, half of beneficiaries with schizophrenia did not submit any claims for APs to Medicaid, nearly half had an emergency room visit, and one-third had an inpatient admission. Moreover, healthcare measures varied considerably across states. These findings may indicate unmet treatment needs for Medicaid beneficiaries with schizophrenia.

Abstract
Although WNT signaling is frequently dysregulated in solid tumors, drugging this pathway has been challenging due to off-tumor effects. Current clinical pan-WNT inhibitors are nonspecific and lead to adverse effects, highlighting the urgent need for more specific WNT pathway-targeting strategies. We identified elevated expression of the WNT receptor Frizzled class receptor 7 (FZD7) in multiple solid cancers in The Cancer Genome Atlas, particularly in the mesenchymal and proliferative subtypes of ovarian serous cystadenocarcinoma, which correlate with poorer median patient survival. Moreover, we observed increased FZD7 protein expression in ovarian tumors compared with normal ovarian tissue, indicating that FZD7 may be a tumor-specific antigen. We therefore developed a novel antibody-drug conjugate, septuximab vedotin (F7-ADC), which is composed of a chimeric human-mouse antibody to human FZD7 conjugated to the microtubule-inhibiting drug monomethyl auristatin E (MMAE). F7-ADC selectively binds human FZD7, potently kills ovarian cancer cells in vitro, and induces regression of ovarian tumor xenografts in murine models. To evaluate F7-ADC toxicity in vivo, we generated mice harboring a modified Fzd7 gene where the resulting Fzd7 protein is reactive with the human-targeting F7-ADC. F7-ADC treatment of these mice did not induce acute toxicities, indicating a potentially favorable safety profile in patients. Overall, our data suggest that the antibody-drug conjugate approach may be a powerful strategy to combat FZD7-expressing ovarian cancers in the clinic.

Abstract
BACKGROUND: Most patients with schizophrenia are diagnosed in their early twenties and often have commercial insurance at diagnosis. These young adults can experience changes in insurance coverage, that is, "churn," which can lead to disruptions in care. OBJECTIVE: To examine the frequency, speed, and type of insurance churn events in a young adult schizophrenia population with commercial insurance coverage at diagnosis. METHODS: The Colorado All-Payer Claims Database, containing insurance claims data from commercial and public insurers for Colorado residents, was used for the study. Eligible patients were required to have at least 1 inpatient or 2 outpatient claims for schizophrenia or schizoaffective disorder, be of age 18-34 years at index, have previous insurance coverage for 12 consecutive months, and have commercial insurance at diagnosis. These patients were 1:5 propensity score matched (PSM) with nonschizophrenia members. Percentages of members on different insurance types were calculated monthly to assess churn events. Cohorts were compared using descriptive statistics, Cox proportional hazards, and generalized estimating equation models. RESULTS: The matched schizophrenia and nonschizophrenia cohorts comprised 501 and 2,510 members, respectively. Before PSM, cohorts were imbalanced (schizophrenia cohort had a younger median age and higher proportion of males). After matching, the cohorts were similar in terms of the matched baseline characteristics. Previous mental health disorders were more common in the schizophrenia cohort (75%) than in the nonschizophrenia cohort (26%). The proportion of members with at least 1 churn event for the schizophrenia and nonschizophrenia cohorts, respectively, were 53.8% vs 36.5% after 12 months and 84.6% vs 69.2% after 48 months. Time to first churn event was significantly shorter in the schizophrenia cohort (16 months) than the nonschizophrenia cohort (23 months; P < 0.001). Schizophrenia cohort members had 64.1 and 56.8 churn events per 1,000 members per month vs 43.0 (P ≤ 0.001) and 42.8 (P = 0.011) churn events for nonschizophrenia cohort members in the first and second 6-month periods, respectively. Proportions of members in the schizophrenia and nonschizophrenia cohorts on public insurance, respectively, were 22.9% vs 6.9% after 12 months and 52.4% and 10.7% after 48 months. In the schizophrenia cohort, the most common churn event type was from commercial to public insurance rather than to a different commercial insurance; notably, 41% of members were still on a commercial plan 4 years after diagnosis. CONCLUSIONS: Young adults with schizophrenia experienced churn events more rapidly and more frequently than those without schizophrenia for the first 4 years studied after the index date. These disruptions may be associated with reduced access to care and treatment gaps in this vulnerable patient population. DISCLOSURES: This research was sponsored by Janssen Scientific Affairs, LLC.

Abstract
Abstract
Aim
SCSS is offered to patients who have persistent chronic neuropathic pain after trials of conservative management. Although severe bleeding complications are rare, it is common practice to take two G&S samples from patients pre-operatively. Unnecessary testing can induce patient anxiety and is a financial burden to the NHS. We aim to determine if a single G&S sample before SCSS would be beneficial, and to assess the association between number of risk factors for bleeding and blood loss in SCSS.
Method
Retrospective analysis of 100 patients in one centre who had SCSS over a 3-year period. Bleeding risk factors, haemoglobin levels and complications were recorded for each patient. A review of current literature along with a cost analysis was subsequently performed.
Results
An average drop in haemoglobin levels of 9g/L post-operatively was seen. No patients required blood transfusions. There was no statistically significant difference (P = 0.364) between number of risk factors and blood loss.
Conclusions
The results obtained suggest that SCSS carries a low risk of adverse bleeding requiring blood transfusions. With the lack of guidelines for preoperative G&S samples it is difficult to make decisions on the amount of samples needed before SCSS. Single G&S sampling in patients without bleeding risk factors can reduce patient burden, save costs, and reduce environmental footprints left by laboratory tests. Those with risk factors may still benefit from two pre-operative G&S samples to ensure patient safety.

Abstract
Abstract
Aim
The COVID-19 pandemic resulted in an upheaval of national surgical guidance on appendicitis, which has previously favoured surgical over conservative approaches. We analysed how these guidelines altered management and outcomes of appendicitis.
Method
A retrospective cohort study at Heartlands Hospital, Birmingham of all appendicitis admissions around and during the first COVID-19 peak was conducted, with analysis of electronic patient records using the acute surgical worklist.
Results
48 admissions for appendicitis during the two-month period from 01/02/20 to 25/03/20 prior to the COVID-19 peak and 28 admissions in the two months during the peak itself from 30/03/20 to 24/05/20 were identified. Prior to the COVID-19 peak, a lower proportion of cases was managed conservatively (18.8%) compared to the latter (67.9%, p < 0.0001). This change also coincided with a switch from laparoscopic to open approaches in those managed surgically. We studied a further period post-COVID-19 peak from 01/06/20 to 26/07/20, where proportions of patients managed conservatively versus surgically did not significantly change following the COVID-19 peak, although surgical preference reverted from open to laparoscopic approaches. During the COVID-19 period, a reduced length of stay was seen in cases managed conservatively (1.65 days) compared to those managed surgically (4 days, p = 0.024). Differences in readmission rates were not statistically significant.
Conclusions
A reduction in numbers of appendicitis presentations as well as a switch to conservative approaches was seen during COVID-19. These findings furthermore support non-inferiority of conservative over open surgical approaches in most appendicitis cases at a time where laparoscopy was deemed unfeasible.

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
Endometriosis is a benign entity defined as the presence of endometrium tissue outside of uterine cavity. It is a common disease involving peritoneum, pelvic organs, gastrointestinal tract, and so on. Diagnosis based on cytology specimen can be challenge when we encounter increased cytological atypia in the glandular epithelium, with abundant inflammatory cells and debris in the background. We presented a case of deep rectal endometriosis mimicking rectal adenocarcinoma on cytology specimen and on MRI imaging studies. The combination of endometrial glands, cellular Mullerian stroma, hemorrhage, and hemosiderin-laden macrophages are the characteristic features on cytologic specimens.

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
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
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
Purpose To systematically review the literature evaluating clinical utility of imaging metrics derived from baseline fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) for prediction of progression-free (PFS) and overall survival (OS) in patients with classical Hodgkin lymphoma (HL) and diffuse large B cell lymphoma (DLBCL). Methods A search of MEDLINE/PubMed, Web of Science, Cochrane, Scopus and clinicaltrials.gov databases was undertaken for articles evaluating PET/CT imaging metrics as outcome predictors in HL and DLBCL. PRISMA guidelines were followed. Risk of bias was assessed using the Quality in Prognosis Studies (QUIPS) tool. Results Forty-one articles were included (31 DLBCL, 10 HL). Significant predictive ability was reported in 5/20 DLBCL studies assessing SUVmax (PFS: HR 0.13–7.35, OS: HR 0.83–11.23), 17/19 assessing metabolic tumour volume (MTV) (PFS: HR 2.09–11.20, OS: HR 2.40–10.32) and 10/13 assessing total lesion glycolysis (TLG) (PFS: HR 1.078–11.21, OS: HR 2.40–4.82). Significant predictive ability was reported in 1/4 HL studies assessing SUVmax (HR not reported), 6/8 assessing MTV (PFS: HR 1.2–10.71, OS: HR 1.00–13.20) and 2/3 assessing TLG (HR not reported). There are 7/41 studies assessing the use of radiomics (4 DLBCL, 2 HL); 5/41 studies had internal validation and 2/41 included external validation. All studies had overall moderate or high risk of bias. Conclusion Most studies are retrospective, underpowered, heterogenous in their methodology and lack external validation of described models. Further work in protocol harmonisation, automated segmentation techniques and optimum performance cut-off is required to develop robust methodologies amenable for clinical utility.

Abstract
AIMS The primary objective was to examine direct costs and health resource utilization (HRU) among commercially insured young adults with schizophrenia (SCZ) in Colorado. MATERIALS AND METHODS The Colorado All-Payer Claims Database, covering approximately 76% of the insured Colorado population was used. Members aged 18-34, with and without SCZ, having commercial insurance were included. All-cause, mental health (MH) related and non-MH related per patient per month (PPPM) costs and per hundred patients per month (PHPPM) HRU were compared between an SCZ cohort and a propensity score matched non-SCZ cohort before and after index date up to 48 months. RESULTS Five hundred and one patients with SCZ and 2,510 matched individuals without SCZ were included. HRU and costs were higher for SCZ patients both pre- and post-index date. Pre-index, there were 32.3 (24.0 MH; 8.4 non-MH) PHPPM more office visits; 2.1 (2.7 MH) PHPPM more admissions; 104.8 (67.02 MH; 37.7 non-MH) PHPPM more prescriptions in the SCZ cohort (all p<.01). After index date, the SCZ cohort had 89.6 (81.3 MH; 9.2 non-MH) more PHPPM office visits, 7.2 (6.1 MH; 0.9 non-MH) PHPPM more admissions, and 181.6 (123.1 MH; 58.6 non-MH) PHPPM more prescriptions (all p<.001). All-cause costs in the pre-index period were $457 PPPM ($373 MH) higher for the SCZ cohort (p<.001). In the post-index period, all-cause costs for the SCZ cohort were $1,687 PPPM ($1,258 MH; $412 non-MH) higher (all p<.001). Approximately, 40% of patients with SCZ were on commercial insurance after four years compared with approximately 75% in the non-SCZ cohort. LIMITATIONS This study was based on data from a single state, thus may not be generalizable to other states. CONCLUSIONS Healthcare costs and HRU for young adults diagnosed with SCZ are significantly more burdensome to commercial payers than matched patients without SCZ, both before and after an official SCZ diagnosis.

Abstract
INTRODUCTION While several sodium glucose co-transporter 2 (SGLT2) inhibitors are approved as an adjunct to diet and exercise to improve glycemic control in patients with type 2 diabetes mellitus (T2DM), there are no clinical trial data providing head-to-head comparisons of the efficacy and safety of these therapies. Real-world analyses can provide valuable evidence on the effectiveness of competing treatments. This study compared the real-world glycemic effectiveness of SGLT2 inhibitors in individuals with T2DM. METHODS Patients who initiated canagliflozin 300 mg versus empagliflozin 25 mg or dapagliflozin 10 mg were identified from the Optum® De-identified Clinformatics® Extended Data Mart-Date of Death database and propensity score matched. Achievement of HbA1c < 8.0% (Healthcare Effectiveness Data and Information Set [HEDIS] target) and > 9.0% (HEDIS poor control) after 6 months of treatment was calculated. RESULTS Post-baseline HbA1c was similar in the canagliflozin and empagliflozin cohorts (7.65% versus 7.57%), as was percent of patients with HbA1c < 8.0% or > 9.0%. Post-baseline HbA1c was lower with canagliflozin versus dapagliflozin (7.58% versus 7.74%; P = 0.0247). The canagliflozin cohort was more likely to achieve HbA1c < 8.0% than the dapagliflozin cohort (P = 0.0292); the likelihood of achieving HbA1c > 9.0% was similar. CONCLUSION In patients with T2DM, HbA1c outcomes were similar with canagliflozin and empagliflozin. Patients on canagliflozin versus dapagliflozin were more likely to have a lower HbA1c and reach HbA1c < 8.0% after 6 months. These results may provide important information for clinicians as they decide the appropriate treatment for their patients with T2DM.

Abstract
PURPOSE Compared to once-monthly paliperidone palmitate (PP1M), once-every-3-months paliperidone palmitate (PP3M) reportedly increases treatment adherence. The objective of this study was to compare treatment patterns, utilization, and costs among Veterans Health Administration (VHA) patients with schizophrenia who transitioned to PP3M versus those remaining on PP1M. PATIENTS AND METHODS Adult VHA patients with ≥2 health care encounters (inpatient or outpatient) that included a schizophrenia diagnosis who initiated PP1M between January 1, 2015, and March 31, 2018 (identification period) were included in this exploratory retrospective cohort study. Propensity scores were used to match cases (PP1M users who transitioned to PP3M during the identification period) with controls (any patient initiating PP1M during the identification period). Data were assessed until death, health plan disenrollment, or study end. Outcomes were compared using chi-square and t-tests. RESULTS A total of 257 eligible PP3M and 2973 eligible PP1M patients were identified among adult VHA patients; mean ages were 53.1 and 53.7 years, respectively. After propensity score matching, the PP3M and PP1M cohorts each held 111 patients. Comorbidities of patients treated with PP3M versus PP1M, respectively, included anxiety (12.5% vs 20%; standardized difference [STD] = 20.6), tobacco use (28.4% vs 43.2%; STD = 31.2), depressive disorder (26.5% vs 36.2%; STD = 21.1), and substance abuse (37.4% vs 44.2%; STD = 13.9). For the PP3M cohort, adherence (proportion of days covered ≥80%) to any antipsychotic agent was higher (78.4% vs 57.7%, P = 0.0009), and all-cause inpatient lengths of stay (LOS) were shorter (3.0 vs 8.3 days, P = 0.0354). Increased all-cause pharmacy costs with PP3M were offset by reduced all-cause medical costs, resulting in overall health care cost-neutrality. CONCLUSION Relative to those remaining on PP1M, VHA patients with schizophrenia who transitioned to PP3M experienced improved antipsychotic medication adherence and significantly shorter all-cause inpatient LOS; costs remained neutral.

Abstract
Casestudy: Clear cell sarcoma (CCS), also known as malignant melanoma of soft parts, is a primary soft tissue neoplasm exhibiting evidence of melanocytic differentiation. It is an uncommon aggressive tumor that arises in tendons and aponeuroses of the distal extremities. Here, we report the first case of primary CCS of the breast.
The patient was a 43-year-old female who presented with a left breast mass and underwent surgical resection at an outside hospital. No history of melanoma or any other malignancies was reported. Grossly, it was described as a 2 x 1.5 x 1.5 cm, well-demarcated, white nodular mass. Microscopic examination showed a malignant neoplasm composed of short spindle cells with ill-defined, eosinophilic cytoplasm and ovoid nuclei with finely stippled chromatin and exhibiting moderate pleomorphism. The lesional cells were arranged in short interlacing fascicles with abundant collagen, with brisk mitotic activity (>15/10 HPF). The differential diagnosis included spindle cell carcinoma, myoepithelial carcinoma and melanocytic neoplasm. The tumor cells were immunoreactive for S-100 protein, SOX10, Mart-1, HMB45 and MiTF, but negative for multiple cytokeratins (including high and low molecular weight keratins), p63, EMA, CEA, Caldesmon, smooth muscle myosin, calponin, desmin, ERG, and CD31, thus confirming melanocytic origin. EWSR1 gene rearrangement was detected by fluorescence in situ hybridization analysis using break-apart probes. Overall, the histomorphology combined with the immunophenotype and cytogenetic characteristics, was most consistent with a CCS. To our knowledge, no primary CCS of the breast has been previously reported in the English language literature.

Abstract
BACKGROUND We evaluated the effect of cardiac resynchronization therapy (CRT) on septal perfusion and thickening at 6 months post implantation assessed on Tc99m-MIBI Gated myocardial perfusion SPECT (GMPS).We also studied the association of change in septal perfusion and thickening with primary outcome defined as at least one [improvement in ≥1NYHA class, left ventricular ejection fraction (LVEF) by ≥ 5%, reduction of end-systolic volume (ESV) by ≥ 15%, and improvement ≥ 5 points in Minnesota living with heart failure questionnaire (MLHFQ)]. METHOD One hundred and five patients underwent clinical and GMPS evaluation before and at 6 months post CRT. RESULT Post CRT there was significant improvement in mean normalized septal perfusion uptake and in septal thickening (P value = 0.001, both). There was no significant relation between improvement in septal perfusion and primary outcome. However, improvement in septal thickening was statistically significant with favorable primary outcome (P = 0.001).There was no significant correlation between improvement of septal perfusion and improvement in LVEF, reduction in End diastolic volume (EDV), ESV, and Left ventricular Dyssynchrony (LVD). But, there was significant correlation between improvement of septal thickening and these parameters. CONCLUSION Improvement in septal thickening was associated with reverse remodeling, improvement in LVEF, and reduction of LVD.

Abstract
Background Schizophrenia is associated with high health care resource utilization and treatment costs. Objective This study compared treatment patterns, health care resource utilization, and medical costs before and after a switch from oral antipsychotic drug (risperidone or paliperidone [RIS/PALI]) therapy to the long-acting injectable once-monthly paliperidone palmitate (PP1M) in patients with schizophrenia. Methods Data for adult patients (aged ≥18 years) with at least 1 diagnosis of schizophrenia who initiated treatment with oral RIS/PALI ≥6 months before switching and had continuous health plan enrollment during the study period before and after the switch were extracted from the Veterans Health Administration database. Treatment patterns, health care resource utilization, and costs were compared between the period 6 or 12 months before and after switching directly from oral RIS/PALI to PP1M. Results The analysis included 676 and 493 patients in the 6-month and 12-month cohorts, respectively. Adherence to oral RIS/PALI during the 12 months preswitch was 11.0% and 22.1% as measured by proportion of days covered and medication possession ratio ≥80%, respectively. During the 12 months postswitch, adherence to PP1M was 27.0% and 35.9%, respectively. Among patients treated with oral RIS/PALI, from 12 months pre- to 12 months post-PP1M switch, fewer all-cause inpatient stays (2.2 vs 1.1, respectively; P < 0.05) and a shorter mean length of inpatient stay (28.1 and 14.0 days, respectively; P < 0.05) were observed. This pattern was similar for both the number of mental health– and schizophrenia-related inpatient stays and length of stay. Compared with 12 months pre-PP1M switch, significantly higher mean numbers of all-cause outpatient visits and pharmacy visits were observed at 12 months postswitch. In line with health care resource utilization findings, at 12 months pre- versus 12 months post-PP1M switch we observed decreases in all-cause inpatient stay costs ($41,886 vs $20,489; P < 0.05) and increases in outpatient visit costs ($22,005 vs $29,069; P < 0.05). Findings for the 6-month cohort followed a similar pattern. Conclusions Post-PP1M switch, a decrease in total medical costs fully offset an increase in pharmacy costs, resulting in similar total costs. The findings suggest potential economic benefits of switching patients with schizophrenia from oral RIS/PALI to PP1M in the Veterans Health Administration.

Abstract
Parvovirus B19 infections are prevalent in children and commonly present as slapped cheek fever, also known as the fifth disease. They are seen frequently in daycares and professions that require close contact with children. The most common presentation is a rash that is prominent on the cheeks; less common symptoms include painful or swollen joints (polyarthopathy syndrome). The infection is self-limited and resolves within one to two weeks. The virus has an affinity to the red blood cell (RBC) precursors and can rarely cause temporary cessation of the bone marrow's RBC production, leading to aplastic anemia. This is especially of significance in patients predisposed to increased RBC destruction, such as hereditary spherocytosis, sickle cell anemia, and other morphological abnormalities of the RBC. The overlapping arrest of RBC production and excessive destruction leads to a transient aplastic crisis (TAC), leading to severe life-threatening anemia, requiring blood urgent blood transfusions. There have been many studies reporting the incidence of TAC in patients with sickle cell crisis. Only a few cases have been reported in patients with hereditary spherocytosis.
