Age-dependent prevalence of type 2 diabetes, cardiovascular risk profiles and use of diabetes drugs in Germany using health claims data.

AIMS: This study evaluates type 2 diabetes mellitus (T2DM) prevalence in Germany, focusing on patients at risk for, or with already established, cardiovascular disease (CVD), as well as their antidiabetic and cardiovascular treatments. MATERIALS AND METHODS: Using anonymized claims data from the WIG2 database, we calculated 2018 T2DM prevalence, extrapolating rates to the German statutory health insurance population. In the study period, 3 376 228 patients were eligible in the database. Forming antidiabetic medication groups, we evaluated treatment regimens of patients at risk for, or with already established CVD, based on the REWIND study criteria. We also evaluated their CVD medication prescriptions. RESULTS: Statutory health insurance extrapolated T2DM prevalence was estimated at 11.9%, with higher prevalence rates in older patients. When only patients with prescriptions of antidiabetic drugs were included, prevalence was 7.6%. At least 94% of patients with T2DM medication had at least one risk factor (without considering age) according to REWIND criteria, while 67%-80% had at least two risk factors depending on treatment received. Patients taking insulin combined with oral therapy comprised the largest proportion of patients with at least two REWIND risk factors. Approximately 85% of all patients with T2DM in the population were treated with antihypertensive medication. CONCLUSIONS: T2DM is widespread and affects older patients particularly. Most patients with T2DM had at least one CV risk factor, and about half already had established CVD. Early prevention of CVD, which disproportionately affects patients with T2DM, is necessary. Furthermore, the treatment of older patients with T2DM with insulin is still common and needs further evaluation.

Clinical characteristics, treatment patterns, and persistence in individuals with type 2 diabetes initiating a glucagon-like peptide-1 receptor agonist: A retrospective analysis of the Diabetes Prospective Follow-Up Registry.

AIMS: To describe clinical characteristics, treatment patterns and glucagon-like peptide-1 receptor agonist (GLP-1 RA) persistence in individuals with type 2 diabetes (T2D) initiating their first GLP-1 RA. MATERIALS AND METHODS: A real-world analysis of adults with T2D initiating GLP-1 RA therapy between 2007 and June 2020 from the multicentre Diabetes Prospective Follow-Up (DPV) Registry, stratified by antidiabetes therapy at the time of GLP-1 RA initiation: oral antidiabetic drugs (OAD), insulin ± OAD or lifestyle modification (LM). GLP-1 RA treatment persistence in individuals with ≥12 months follow-up was determined by Kaplan-Meier analysis. RESULTS: Overall, 15 111 individuals with T2D initiating GLP-1 RA therapy (55% men) were identified; median [interquartile range (IQR)] age [58.7 (50.6-66.7) years], diabetes duration [8.5 (3.6-14.7) years], glycated haemoglobin [HbA1c; 8.2 (7.1-9.8)%]. Median (95% confidence interval) GLP-1 RA persistence in eligible individuals (n = 5189) was 11 (10-12) months; OAD 12 (11-14) months (n = 2453); insulin ± OAD 11 (9-12) months (n = 2204); and LM 7 (5-9) months (n = 532). Median treatment persistence tended to increase from 2007-2012 to 2017-2020. Median (IQR) HbA1c decreased from baseline [8.2 (7.1-9.8)%] to discontinuation [7.5 (6.6-8.7)%], with a greater decrease observed in individuals with persistence >12 months versus ≤12 months. Individuals who discontinued GLP-1 RA therapy predominantly switched to insulin (if not already using) or dipeptidyl peptidase-4 inhibitors. CONCLUSION: Real-world registry data revealed improved outcomes with longer median GLP-1 RA persistence; ~50% of patients overall achieved HbA1c <7% at 12 months. Persistence was highest with baseline OAD and/or insulin, and tended to increase over the period 2007-2020.

Artificial intelligence for online characterization of ultrashort X-ray free-electron laser pulses.

X-ray free-electron lasers (XFELs) as the world's brightest light sources provide ultrashort X-ray pulses with a duration typically in the order of femtoseconds. Recently, they have approached and entered the attosecond regime, which holds new promises for single-molecule imaging and studying nonlinear and ultrafast phenomena such as localized electron dynamics. The technological evolution of XFELs toward well-controllable light sources for precise metrology of ultrafast processes has been, however, hampered by the diagnostic capabilities for characterizing X-ray pulses at the attosecond frontier. In this regard, the spectroscopic technique of photoelectron angular streaking has successfully proven how to non-destructively retrieve the exact time-energy structure of XFEL pulses on a single-shot basis. By using artificial intelligence techniques, in particular convolutional neural networks, we here show how this technique can be leveraged from its proof-of-principle stage toward routine diagnostics even at high-repetition-rate XFELs, thus enhancing and refining their scientific accessibility in all related disciplines.

Patient Preferences: Results of a German Adaptive Choice-Based Conjoint Analysis (Market Research Study Sponsored by Eli Lilly and Company) in Patients on Palliative Treatment for Advanced Breast Cancer.

INTRODUCTION: Integration of patient preferences into shared decision making improves disease-related outcomes, but such data from patients with advanced breast cancer (aBC) are limited. The objective of this study was to demonstrate the relative importance of overall survival (OS) and progression-free survival (PFS) in relation to quality of life (QoL) and therapy-associated side effects from the perspective of patients with aBC. METHODS: Postmenopausal patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative aBC receiving first- or second-line treatment were recruited throughout Germany. Patient-relevant attributes for aBC therapy assessment were collected using a stepwise multimodal approach. A conjoint matrix was developed, resulting in 2 attributes for therapy goals (OS and PFS), 4 for QoL, and 6 for side effects. An online quantitative survey was then performed using adaptive choice-based conjoint (ACBC) methodology. RESULTS: The quantitative survey included 104 patients: 67 (64.4%) receiving first-line treatment and 37 (35.6%) receiving second-line treatment. The QoL attribute "physical agility and mobility" received the highest utility score (19.4 of 100%), reflecting the greatest importance to patients, followed by treatment goals (OS [15.2%] and PFS [14.4%]). Therapy-related side effects were less important, with nausea/vomiting being the most important (9.3%), followed by infection (6.4%) and hair loss (5.0%). The McFadden pseudo R2 (0.805), the root likelihood (0.864), and the χ2 test (2,809.041; p < 0.0001) indicated a very good fit of the statistical model. CONCLUSION: Using ACBC analysis, it appears that QoL, OS, and PFS are most important to postmenopausal patients with aBC in relation to cancer treatment. Side effects seem to be less important if OS or PFS are prolonged and the QoL is maintained. Thus, QoL, OS, and PFS should be considered equally when making treatment decisions in aBC.

Patient characteristics of insulin lispro 200 units/mL users in real world setting in Germany.

OBJECTIVE: Insulin lispro 200 U/mL (IL200) is a treatment choice for people with diabetes who have daily mealtime insulin (MTI) requirements of >20 U/day. We report clinical characteristics of real world IL200 users in Germany to understand clinical settings and the type of patients who would benefit from IL200 treatment. METHODS: This retrospective database analysis used the patient-level data from "IMS Disease Analyzer" in Germany from February 2015 to June 2016. Clinical and demographic information were collected and analyzed for IL200 users alongside that of those who were using more than 20 U a day of 100 U/mL analog MTI. RESULTS: Of the 17,261 patients using insulin, 811 were identified in IL200 group. The IL200 group had 60% men, mean ± SD age of 63.6 ± 11.9 years, and BMI of 36.2 ± 6.7 kg/m2. Of these, 63.5% (n = 515) were seen by diabetologists, while 36.5% (n = 296) were seen by general practitioners (GPs). In the IL200 group, 77.7% used basal insulin concomitantly, >90% had ≥1 comorbidity, and 52% had ≥4 comorbidities; the most common being hypertension (75.2%), neuropathy (66.0%), and nephropathy (59.6%). Diabetologist-treated IL200 users were more likely to have multiple comorbidities as compared with those treated by GPs (15.0% vs. 12.9% for >5 comorbidities). CONCLUSIONS: IL200 is prescribed to people with diabetes who need more than 20 U/day of mealtime insulin and tend to be more obese, older, and with multiple comorbidities. Future research should explore how concentrated MTI can impact adherence and long-term glycemia.

Utilization patterns of glucagon-like peptide-1 receptor agonists in patients with type 2 diabetes mellitus in Germany: a retrospective cohort study.

OBJECTIVE: This retrospective database analysis complements previous research to understand treatment patterns for German patients newly-initiating or switching to subsequent GLP-1 RAs. METHODS: Adult patients (≥18 years) initiating GLP-1 RA (Cohort 1 [C1]) or switching from a previous GLP-1 RA (Cohort 2 [C2]) to exenatide twice-daily (exBID), exenatide once-weekly (exQW), dulaglutide (DULA), or liraglutide (LIRA) were included in this analysis using IQVIA LRx from January 1, 2014-March 31, 2017. Patients were required to have ≥1 oral anti-hyperglycemic prescription during the 6-month pre-index period and ≥12 months follow-up. Persistence and treatment modifications were assessed within and beyond 12 months follow-up. Average daily/weekly dosage (ADD/AWD) was calculated during persistence. RESULTS: C1 included 13,417 patients, while C2 included 4,264 patients. Mean ± standard deviation (SD) age was similar (57.7 ± 11.1 years [C1], 58.9 ± 10.1 years [C2]). Most patients using DULA in C2 had switched from LIRA (56.6%). For C1, mean ADD for LIRA was 1.41 ± 0.10 mg, slightly higher in C2, and increased over time. ADD for exBID was 16.9 ± 1.0 mcg, slightly greater in C2. AWD was 2.00 ± 0.05 mg for exQW users and 1.42 ± 0.03 mg for DULA users in C1, similar to C2. For C1, 27.0% exBID, 35.3% exQW, 50.9% DULA, and 48.1% LIRA users remained persistent at 12 months. Patients using DULA had a higher probability of remaining persistent over time (Kaplan-Meier) for both cohorts. CONCLUSIONS: Patients using DULA had the highest probability of remaining persistent over time, followed by LIRA. ADD/AWD for DULA, exQW, and exBID were aligned with the recommended combination therapy dose; LIRA ADD suggests some patients use the 1.8 mg dose.

Epidemiology of Adult Soft-Tissue Sarcomas in Germany.

We conducted a retrospective cohort study using data compiled from the regional German cancer registries by the Centre for Cancer Registry Data (ZfKD) at the Robert Koch Institut (RKI) to describe the epidemiology of adult soft-tissue sarcomas (STS) in Germany in 2003-2012, focusing on advanced STS. We identified 33,803 incident adult cases of STS (other than the Kaposi sarcoma and gastrointestinal stromal tumors). The incidence of STS was 6.05 (95% confidence interval (CI), 5.82-6.29) per 100,000 in 2012 (4,079 cases). During 2003-2012, the most common histologic categories were leiomyosarcoma (19%), liposarcoma (16%), and STS not otherwise specified (14%). The overall STS-specific mortality rate in 2012 was 2.31 (95% CI, 2.06-2.57) per 100,000, and the median overall survival from initial diagnosis was 5.83 (95% CI, 5.50-6.08) years. Using STS mortality rates as a proxy for incidence of advanced STS in Germany and applying the age- and sex-specific rates to the corresponding German population, we estimated that 1,581 incident adult advanced STS cases occurred in Germany in 2012. Our findings contribute to a refined understanding of the population burden of STS in Germany, including the number of patients with advanced STS who may be candidates for systemic treatment.

Estimating the real world daily usage and cost for exenatide twice daily and liraglutide in Germany, the Netherlands, and the UK based on volumes dispensed by pharmacies.

BACKGROUND: Glucagon-like peptide-1 (GLP-1) receptor agonists are indicated for improvement of glycemic control in adults with type 2 diabetes. Cost is one aspect of treatment to be considered, in addition to clinical benefits, when selecting optimal therapy for a patient. The objective of this study was to estimate the average dose usage and real world daily cost of the GLP-1 receptor agonists, exenatide twice daily and liraglutide once daily, in Germany, the Netherlands, and the UK. METHODS: Administrative databases were used to source the data from longitudinal records of dispensed prescriptions. Data were extracted from the IMS Longitudinal Prescription database which captures details of prescriptions dispensed in pharmacies. Information on the dispensed quantity of each product was used to estimate average daily usage per patient. Daily dose usage was multiplied by the public price per unit to estimate daily cost. RESULTS: The dispensed volume in Germany corresponded to a mean dispensed daily dose of 16.81 µg for exenatide twice daily and 1.37 mg for liraglutide (mean daily cost €4.02 and €4.54, respectively). In the Netherlands, average dispensed daily doses of 17.07 µg and 1.49 mg were observed for exenatide twice daily and liraglutide (mean daily cost €3.05 and €3.97, respectively). In the UK, the mean dispensed volume corresponded to a daily usage of 20.49 µg for exenatide twice daily and 1.50 mg for liraglutide (mean daily cost £2.53 and £3.28, respectively). CONCLUSION: Estimates of average daily dispensed doses of GLP-1 receptor agonists derived from pharmacy data in real world settings corresponded to the dosing recommendation of the summaries of product characteristics. Nevertheless, the mean daily cost of exenatide twice daily was lower than that of liraglutide in Germany, the Netherlands, and the UK. Such estimates can be used to inform health care decision-makers on the real world usage and cost of medications effective in achieving glycemic control in patients with type 2 diabetes.
