  • Clinical effectiveness of liraglutide vs basal insulin in a real-world setting: Evidence of improved glycaemic and weight control in obese people with type 2 diabetes.Abstract

    AIMS: To compare real-world antidiabetic treatment outcomes over 12 months in obese people with type 2 diabetes mellitus (T2DM) who previously received oral antidiabetic therapy and then initiated a first injectable therapy with liraglutide or basainsulin. PATIENTS AND METHODS: This was a retrospective, propensity score-matched, longitudinal cohort study using real-world data (January 2010 to December 2015) from the Dutch PHARMO Database Network

  • Exploring methods for comparing the real-world effectiveness of treatments for osteoporosis: adjusted direct comparisons versus using patients as their own control.Abstract

    Using Swedish and Dutch registry data for women initiating bisphosphonates, we evaluated two methods of comparing the real-world effectiveness of osteoporosis treatments that attempt to adjust for differences in patient baseline characteristics. Eah method has advantages and disadvantages; both are potential complements to clinical trial analyses

  • Immortal time bias in pharmacoepidemiological studies on cancer patient survival: empirical illustration for beta-blocker use in four cancers with different prognosis.Abstract

    Immortal time bias (ITB) is still seen frequently in medical literature. However, not much is known about this bias in the field of cancer (pharmaco-)epidemiology. In context of a hypothetical beneficial beta-blocker use among cancer patients, we amed to demonstrate the magnitude of ITB among 9876 prostate, colorectal, lung and pancreatic cancer patients diagnosed between 1998 and 2011, which were selected from a database linkage of the Netherlands Cancer Registry and the PHARMO Database Network

  • Statin Use After Diagnosis of Colon Cancer and Patient Survival.Abstract

    BACKGROUND & AIMS: Statin use has been associated with a reduced incidence of colorectal cancer and might also affect survival of patients diagnosed with colon cancer. Statins are believed to inhibit Ras signaling and may also activate the bone morhogenetic protein (BMP) signaling pathway in colorectal cancer cells

  • Pre- and post-diagnostic beta-blocker use and lung cancer survival: A population-based cohort study.Abstract

    Beta-blockers have been associated with decreased cancer mortality. However, evidence for lung cancer is sparse and reported beneficial effects might be based on biased analyses. In this so far largest study we investigated the association betweeneta-blocker use and lung cancer survival. Therefore, patients with a lung cancer diagnosis between April 1998 and December 2011 were selected from a database linkage of the Netherlands Cancer Registry and the PHARMO Database Network

  • Pre- and post-diagnostic beta-blocker use and prognosis after colorectal cancer: Results from a population-based study.Abstract

    Recent experimental and epidemiological studies have suggested that beta blocker use might be associated with better cancer prognosis, but results were inconclusive and only few studies have investigated the association specifically for colorectalancer (CRC) patients. We investigated this hypothesis using a linked dataset of the Eindhoven area of the Netherlands Cancer Registry and the PHARMO record linkage, including patients diagnosed with CRC between 1998 and 2011

  • No association between metformin use and survival in patients with pancreatic cancer: An observational cohort study.Abstract

    Several studies have suggested an association between use of metformin and an increased overall survival in patients diagnosed with pancreatic cancer, however with several important methodological limitations. The aim of the study was to assess theassociation between overall survival, pancreatic cancer, and metformin use

  • No decreased risk of gastrointestinal cancers in users of metformin in The Netherlands; a time-varying analysis of metformin exposure.Abstract

    Previous studies on metformin use and gastrointestinal (GI) cancer risk have yielded inconclusive results on metformin’s chemoprotective effects. We aimed to evaluate GI cancer risk in users of metformin in The Netherlands using a time-varying apprach in a large population-based database. A cohort study was performed using the NCR-PHARMO database

  • The difference in association between aspirin use and other thrombocyte aggregation inhibitors and survival in patients with colorectal cancer.Abstract

    BACKGROUND: Several studies have suggested that the association between aspirin and improved cancer survival is mediated through the mechanism of aspirin as thrombocyte aggregation inhibitors (TAI). The aim of this study was to provide epidemiologial evidence for this mechanism assessing the association between overall survival and the use of aspirin and non-aspirin TAI in patients with colorectal cancer

  • Asthma-Related Outcomes in Patients Initiating Extrafine Ciclesonide or Fine-Particle Inhaled Corticosteroids.Abstract

    PURPOSE: Extrafine-particle inhaled corticosteroids (ICS) have greater small airway deposition than standard fine-particle ICS. We sought to compare asthma-related outcomes after patients initiated extrafine-particle ciclesonide or fine-particle IC(fluticasone propionate or non-extrafine beclomethasone)
