Methods: Patients wereincluded in the study if they had at least one diagnosis claim for Parkinson’s disease(International Classification of Diseases, 9thRevision, Clinical Modification code 332.xx) during the identification period (01JUL2008-31DEC2010). The first Parkinson’s disease diagnosis claim date was designated as the index date. Patients were requiredto be age ?65 and have continuous health plan enrollment with medical benefitsfor 6 months pre- and post-index date. Residents in a LTC facility were defined asstudy patients using two quarterly assessments recorded in the MDS during the6-month baseline period. Demographic and clinical characteristics and follow-uphealth care costs and utilizations were described. Results: After 1:1 matching,1,620 patients were included in each group (disease and control patients), and thebaseline characteristics were well-balanced. Patients with Parkinson’s diseasewere more likely to have inpatient stays (14.26% vs. 9.51%, p<0.0001), outpatientvisits (47.72% vs. 41.11%, p=0.0002), skilled nursing facility (SNF) visits (20.37% vs.4.51%, p<0.0001), hospice visits (8.64% vs. 1.36%, p<0.0001), and part D pharmacyvisit (62.65% vs. 53.33%, p<0.0001). Compared to control patients, higher all-causehealth care costs were also observed for Parkinson’s disease patients, includinginpatient costs ($2,451 vs. $1,301, p<0.0001), SNF costs ($2,503 vs. $778, p<0.0001),hospice costs ($1,164 vs. $245, p<0.0001), total outpatient costs ($4,477 vs. $1,304,p<0.0001), pharmacy costs ($695 vs. $1,399, p<0.0001) and total costs ($9,775 vs.$5,314, p<0.0001). Conclusions: During a period of 12 months, patients diagnosed with Parkinson’s disease had higher health care utilization and costs thanmatched control patients.Article Conference Object Examination of the Economic Burden of Dyslipidemia in the Veterans Health Administration Population(2016) Keshishian, A; Tan, H; Xie, L; Başer, Onur...Conference Object Assessing Health Care Resource Utilization and Costs Among Us Veterans Diagnosed With Asthma(2016) Ogbomo, A; Tan, H; Kariburyo, F; Xie, L; Başer, Onur...Conference Object Treatment Patterns Among Newly Diagnosed Multiple Myeloma Patients in the United States Veteran Population (2010-2015)(2016) Parikh, K; Pandya, S; Abouzaid, S; Başer, Onur; Xie, L; Patel, MI....Book Part Mathematics for Social Sciences(Emerald Group Publishing Limited, 2016) Öztürk, MuratAll students enrolled in Business and Economics programs receive basic tarining in quantative methods used in subject that required mathematics and statistics.Article Ekonomik Öncü Göstergelerinin Bes Katılımcı Sayısı Üzerindeki Etkisi(Maliye Finans Yazıları Dergisi, 2014) Kılıç, ErdemEkonomik öncü göstergelerinin Bireysel Emeklilik Sistemi (BES) katılımcı sayısı üzerindeki etkisi sayıma dayalı olan yöntemler ile araştırılmıştır. Geçinme endeksinde bulunan tüm değişkenler ile katılımcı sayısı arasında pozitif bir ilişki bulunmuştur. Harcamalar, BES katılımcı sayısı üzerinde pozitif bir etkiye sahipken, katılımcı sayısı tasarruflar ele alındığında düşmektedir. Dayanıksız mallar ve hizmetler için yapılan harcamalar katılımcı sayısı üzerinde büyük bir etkiye sahiptirler. Enflasyon ve BES katılımcı sayısı arasında anlamlı bir ilişki bulunmaktadır. BES katılımı ile ilgili ileriye yönelik projeksiyonlarda, devlet katkı payının ve toplumdaki BES’e ilişkin bilinçlenmenin etkileri analize dahil edilmelidir.Conference Object Conference Object Institutional Investor Behavior in X-Capm(2019) Kılıç, ErdemThis study aims to model institutional investor behavior in the XCAPM model underthe premise of reflecting a more detailed decomposition of investor types in equitymarkets. We explore the behavior and its impact in the model, esp. on pricing andon key financial ratios. We observe that the prevalence of the institutional investorcounteracts extrapolator’s effects, resulting in lower volatility of price dividendratio, lower predictive power of changes in consumption for future price changesand lower equity premiumConference Object Long-Term Increased Inpatient and Outpatient Visits Associated With Cardiovascular Events: a Large United States Real World Study(2015) Fox, Kathleen M; Wang, L; Quek, RGW; Gandra, SR; Li, L; Başer, OnurBook Part Staatsverschuldung Unter Politökonomischen Gesichtspunkten(Peter Lang GmbH, Internationaler Verlag der Wissenschaften, 2015) Kılıç, ErdemObwohl es in der wissenschaftlichen Literatur, die sich mit der politischen Ökonomie der Staatsverschuldung beschäftigt, verschiedene Meinungen über Gründe exzessiver Staatshaushaltsdefizite gibt, setzt sich mittlerweile die Erkenntnis durch, dass das Ausmaß der Staatsverschuldung auf das institutionelle Gefüge zurückzuführen ist, das Einfluss auf die Schuldenaufnahme nimmt. Während die Theorierichtung der electoral institutionalists die Wahlsysteme (electoral systems) als ausschlaggebend betrachtet, legen die fiscal institutionalists die Priorität auf die Regierungsinstitutionen (governmental institutions), in denen der jährliche Staatshaushalt gestaltet wird. Ziel dieser Arbeit ist es, den Einfluss von politökonomischen Prozessen und der Gestaltung von Budgetinstitutionen auf die Höhe des Staatsdefizits bzw. der Staatsverschuldung zu veranschaulichen. Zu Anfang werden die Bestimmungsgründe der Staatsverschuldung aus der traditionellen Sicht der Finanzwissenschaft dargestellt. Im weiteren Verlauf wird die Rolle der Staatsverschuldung im politischen Prozess untersucht, das Verhalten der Staatsverschuldung in einem Generationenmodell behandelt und der Einfluss der Wahlen bzw. der Wahlverfahren auf die Staatsverschuldung untersucht. Anhand einer neu etablierten Theorierichtung in der politischen Ökonomie, werden im naechsten Abschnitt die Verhandlungsstrukturen während der Budgetprozesse und die institutionellen Implikationen von Budgetprozessen untersucht. Der folgende Abschnitt stellt einige Aspekte einer fiskalischen Verfassung dar, die die Staatsverschuldung bestimmen. Für die Ergebnisse der verschiedenen Theorieansätze wird die empirische Evidenz überprüft und ein empirischer Überblick über die Budgetinstitutionen in den US-amerikanischen Staaten und den EU-Staaten gegeben. Der letzte Abschnitt liefert eine Abschlussbetrachtung und beurteilt den Erklärungsgehalt der theoretischen Modelle.Conference Object Mortality and Prevalence of Major Depressive Disorder in the Us Medicare Population From 2008-2013(2016) Bashyal, R; Du, H; Wang, L; Yuce, H; Başer, Onur...Conference Object Assessing the Economic Burden and Health Care Utilization of Attention Deficit/Hyperactivity Disorder Among Us Medicaid Patients(2016) Zhang Q; Zhao, Y; Keshishian, A; Xie, L; Yuce, H; Başer, Onur...Conference Object Examining the Prevalence and Incidence Rates Among Patients With Depressive Disorder in the Us Veteran Population(2016) Pandya, S; Du, H; Wang, L; Başer, Onur...Article Sektörel Reel Efektif Döviz Kurları: Türkiye Örneği(Ekonomik Mali Yayınlar, 2017) Karamollaoğlu, NazlıBu çalışmanın amacı Türk imalat sanayii alt sektörleri için reel efektif döviz kuru serilerini hesaplamaktadır. Sektörel veya firma düzeyinde yapılan ampirik çalış- malarda döviz kuru serileri genellikle ülke düzeyinde (toplulaştırılmış) kullanıl- maktadır. Sektörler arasındaki ihracat ve ithalat partneri değişkenliği göz önün- de bulundurulunca, ülke seviyesinde hesaplanan ihracat ve ithalat ağırlıkları ile oluşturulan reel efektif döviz kurlarının uygunluğu tartışma konusudur. Bu alan- da yapılan çalışmalarda sektörel döviz kurlarının sektörel rekabet dinamiklerini daha doğru yansıttıkları ve bu sayede ekonomik değişkenlerin açıklanmasında toplulaştırılmış seviyedeki döviz kurlarından daha etkili oldukları rapor edilmiştir. Yapılan basit korelasyon analizinde sektörel kurların toplulaştırılmış kurlarla yük- sek korelasyona sahip olmakla beraber toplulaştırılmış kurlardan farklı yönlerde hareket edebildikleri gözlemlenmektedirArticle Citation - WoS: 24Citation - Scopus: 28Prevalence of Mastocytosis and Hymenoptera Venom Allergy in the United States(2021) Volertas, Sofija; Akın, Cem; Khokhar, Dilawar; Schuler, Charles F; Chen, Lu; Yüce, Huseyin; Montejo, Jenny M; Başer, OnurBackground : Mastocytosis is a risk factor for hymenoptera venom anaphylaxis (HVA). Current guidelines recommend measuring tryptase in HVA patients and that those with mastocytosis pursue lifelong venom immunotherapy (VIT). Available data on HVA and mastocytosis largely derives from European single-center studies and the prevalence of HVA with and without mastocytosis in the United States (US) is unknown.Objective : We sought to determine the prevalence of HVA and mastocytosis in the US using an insurance claims database and evaluate the impact of mastocytosis on VIT in HVA patients in a US cohort. Methods :The IBM Watson Database, consisting of insurance claims from approximately 27 million US patients in 2018, was queried to identify patients with HVA and/or mastocytosis. Further, a retrospective study of 161 patients undergoing VIT between 2015 – 2018 at the University of Michigan (U-M) was conducted. Results :In the IBM Watson Database, the prevalence of HVA was 167 per 100,000 (0.167%) and the prevalence of mastocytosis 10 per 100,000 (0.010%) overall and 97 per 100,000 (0.097%) among those with HVA. Mastocytosis showed a 9.7-fold increase among HVA patients versus the general population. In the U-M cohort, 2.6% of VIT patients had mastocytosis. Tryptase level did not correlate with venom reaction severity but was higher in patients with systemic VIT reactions. Conclusions :We observed a lower US HVA prevalence than previously reported. Mastocytosis was more common in US HVA patients, though at lower rates than previously reported. In VIT patients there was no correlation between tryptase level and reaction severity.
