Background Tenosynovial giant cell tumor (TGCT) is a rare, locally aggressive neoplasm arising from the synovium of joints, bursae, and tendon sheaths affecting small and large joints. It represents a wide spectrum ranging from minimally symptomatic to massively debilitating. Most findings to date are mainly from small, retrospective case series, and thus the morbidity and actual impact of this rare disease remain to be elucidated. This study prospectively explores the management of TGCT in tertiary sarcoma centers. Methods The TGCT Observational Platform Project registry was a multinational, multicenter, prospective observational study involving 12 tertiary sarcoma centers in 7 European countries, and 2 US sites. This study enrolled for 2 years all consecutive ≥ 18 years old patients, with histologically diagnosed primary or recurrent cases of diffuse-type TGCT. Patient demographic and clinical characteristics were collected at baseline and every 6 months for 24 months. Quality of life questionnaires (PROMIS-PF and EQ-5D) were also administered at the same time-points. Here we report baseline patient characteristics. Results 166 patients were enrolled between November 2016 and March 2019. Baseline characteristics were: mean age 44 years (mean age at disease onset: 39 years), 139/166 (83.7%) had prior treatment, 71/166 patients (42.8%) had ≥ 1 recurrence after treatment of their primary tumor, 76/136 (55.9%) visited a medical specialist ≥ 5 times, 66/116 (56.9%) missed work in the 24 months prior to baseline, and 17/166 (11.6%) changed employment status or retired prematurely due to disease burden. Prior treatment consisted of surgery (i.e., arthroscopic, open synovectomy) (128/166; 77.1%) and systemic treatments (52/166; 31.3%) with imatinib (19/52; 36.5%) or pexidartinib (27/52; 51.9%). Treatment strategies at baseline visits consisted mainly of watchful waiting (81/166; 48.8%), surgery (41/166; 24.7%), or targeted systemic therapy (37/166; 22.3%). Patients indicated for treatment reported more impairment compared to patients indicated for watchful waiting: worst stiffness NRS 5.16/3.44, worst pain NRS 6.13/5.03, PROMIS-PF 39.48/43.85, and EQ-5D VAS 66.54/71.85. Conclusion This study confirms that diffuse-type TGCT can highly impact quality of life. A prospective observational registry in rare disease is feasible and can be a tool to collect curated-population reflective data in orphan diseases.

Clinical trials indicate that the use of fixed-dose combinations (FDCs) is associated with a higher level of treatment adherence and prolonged blood pressure (BP) control. The aim of this study was to document the safety and effectiveness of the FDC olmesartan/amlodipine/hydrochlorothiazide in patients with essential hypertension in clinical practice. This multicenter, prospective, 24-week, noninterventional study enrolled 5,831 patients from primary care offices in Germany and Austria. Inclusion criteria were a diagnosis of essential hypertension and newly initiated treatment with the FDC. The mean age of patients was 63.5 years, almost 50% of patients had a time since diagnosis of essential hypertension of over 5 years, and approximately 70% of patients had at least one cardiovascular risk factor, including 29.4% of patients with diabetes mellitus. Following approximately 24 weeks of treatment, the mean reduction in systolic/diastolic BP was 29.0/14.0 mmHg, a BP response was observed by 94.2% of patients, and a target BP of <140/90 mmHg was attained in 67.5% of patients. At least one adverse drug reaction (ADR) was experienced by 1.2% of patients, with the most common being peripheral edema. Subanalyses demonstrated that the following factors did not have a significant influence on the ADR rate: age (<65 years versus ≥65 years), diabetes mellitus (no/yes), cardiovascular risk (low/high), and concomitant medication (no/yes). This study demonstrates that in clinical practice, treatment with the three-drug combination as an FDC tablet resulted in a very high proportion of patients with a BP response and control, accompanied by a very low rate of ADRs.

Background and objectives Recent findings from randomized clinical trials indicate an improved patient adherence and blood pressure (BP) control by using fixed-dose combinations (FDCs) in the treatment of hypertension. The aim of the present study was to verify those data in a large real-world sample of hypertensive patients and to cross-check adherence evaluation performed by physicians and patients self-assessment. Methods A European multi-center, prospective, 24-week, non-interventional study was conducted including 14,979 patients with essential hypertension and new treatment with olmesartan, amlodipine and hydrochlorothiazide as an FDC. Patients’ adherence was measured using the Morisky Medication Adherence Scale (MMAS-8) and a non-standardized questionnaire was used by physicians and patients for self-assessment. Results The mean age of the patients was 63.9 ± 11.78 years and 46.5 % were women. One or more cardiovascular risk factors were present in 71.9 % of patients and 94.7 % had been treated for hypertension before study entry. Mean adherence to medication by MMAS-8 improved from 6.0 to 6.9 at study end. Corresponding improvements of adherence were seen on physicians’ and patients’ self-assessments throughout the study. Mean decrease of systolic/diastolic BP was 26.4/12.8 mmHg without a relevant difference between the MMAS-8 adherence levels. BP target achievement improved from 55.3 to 67.7 % in patients with low versus high adherence. The overall rate of patients with adverse drug reactions was very low (1.76 %) but more frequent in patients with low adherence. Conclusions Our data confirm previous clinical trial data on the improvement of medication adherence by switching antihypertensive combination therapy to an FDC and a subsequent improvement in BP target achievement. An observed trend toward a reduction in adverse drug reactions needs to be further investigated in clinical trials.

Background Venous thromboembolism (VTE, including deep vein thrombosis [DVT] and pulmonary embolism [PE]) has an annual incidence rate of 104–183 per 100,000 person-years. After a VTE episode, the two-year recurrence rate is about 17%. Consequently, effective and safe anticoagulation is paramount. Edoxaban is a direct oral anticoagulant (DOAC) approved VTE treatment. Current safety and efficacy data are derived from clinical trials, and information about treatment durations beyond 12 months are not available. Methods ETNA-VTE-Europe is an 18-month prospective, single-arm, non-interventional, multinational post-authorisation safety study. Approximately 310 sites across eight European countries (Austria, Belgium, Germany, Ireland, Italy, the Netherlands, Switzerland and the United Kingdom) will participate in the study, with the intention to represent the regional distributions of centres, healthcare settings and specialties. An estimated cohort of 2700 patients will be recruited, the only enrolment criteria being acute symptomatic VTE, no participation in an interventional study, and treating physician decision to prescribe edoxaban independently from the registry. Data from patient medical records and/or telephone interviews will be collected at baseline, 1, 3, 6, 12 and 18 months. The primary objective is to evaluate the 18-month rate of symptomatic VTE recurrence in patients with VTE treated with edoxaban outside a clinical trial. The co-primary objective is to evaluate the real-world rates of bleeding and adverse drug reactions. Secondary outcomes include rates of other patient-relevant safety events, adherence to and discontinuation of edoxaban. Furthermore, 12-month ETNA-VTE-Europe data will be considered in the context of those for patients receiving different anticoagulants in the PREFER in VTE registry and Hokusai-VTE clinical trial. Conclusions ETNA-VTE-Europe will allow the safety and effectiveness of edoxaban to be evaluated over an extended period in acute symptomatic VTE patients encountered in routine clinical practice. Findings will be informative for European practitioners prescribing edoxaban as part of real-world VTE treatment/prevention. Trial registration ClinicalTrials.gov Identifier: NCT02943993 .

The safety and efficacy of olmesartan 40 mg and hydrochlorothiazide (HCTZ) as a fixed-dose combination has been investigated in clinical trials leading to its approval. The aims of the present study were to confirm these data in an unselected patient population in daily practice and to determine the impact of physical activity on blood pressure control. In a multicenter, noninterventional study, 3,333 patients with either insufficient blood pressure control on olmesartan 40 mg alone or on a fixed/free combination of olmesartan 40 mg and HCTZ 12.5/25 mg were primarily assessed for safety and tolerability of the fixed-dose combination of olmesartan 40 mg and HCTZ 12.5/25 mg at 24 ± 2 weeks. Secondary objectives were blood pressure reduction, treatment compliance, and impact of physical activity as measured by the sum of weekly energy costs. The mean patient age was 63.2 ± 11.46 years, mean baseline blood pressure was 159.6 ± 15.28/93.5 ± 9.52 mmHg, and 70.9% had at least one additional cardiovascular risk factor. Adverse drug reactions were rare (n = 19), and no serious adverse drug reactions occurred. Compliance with drug therapy was at least sufficient in more than 99% of patients at the end of the study. Blood pressure at the last available visit was reduced by 26.1 ± 15.5/13.0 ± 10.1 mmHg versus baseline (P < 0.0001), but had reduced effectiveness in patients ≥75 years with diabetes or impaired renal function. In 69% of patients, blood pressure was normalized (<140/90 mmHg). No noteworthy differences in baseline characteristics or baseline blood pressure were found between patients with an activity level (sum of weekly energy costs) above or below the median of 9,460.6. A higher versus lower physical activity score had no impact on blood pressure reduction. Our data confirm randomized trial data concerning safe and efficient blood pressure reduction using a fixed-dose combination of olmesartan 40 mg and HCTZ 12.5/25 mg in a large, unselected patient population, independent of physical activity level.

Objectives: To assess the efficacy and tolerability of a fixed-dose combination of olmesartan and amlodipine in an unselected population of patients in primary care and to compare the results with recent randomized controlled trial evidence. Methods: A multicenter, noninterventional, noncontrolled observational study with 8241 hypertensive patients seen by 2187 physicians in daily practice. Blood pressure (BP) reduction, comorbid disease, pharmacotherapy, and tolerability were documented over a 12–18-week observational period. Results: Patients had a mean age of 62.8 ± 11.8 years (48.1% female), and 74.8% had at least one comorbid risk factor or condition. In total, 51.3% received olmesartan-amlodipine 20/5 mg, 30.6% received 40/5 mg, and 17.9% received 40/10 mg at baseline, mostly because of lack of efficacy on prior antihypertensive therapy (73.8%). BP at baseline was 161.8 ± 16.6/93.6 ± 10.2 mmHg (39.8% had Grade 2 hypertension), and the observed BP reduction was -29.0 ± 17.1/-13.5 ± 10.9 mmHg (P < 0.0001), with a significant correlation between BP at baseline and BP reduction (Spearman’s Rho -0.811 for systolic BP and -0.759 for diastolic BP). BP reduction appeared to be dependent on dose and prior antihypertensive therapy, but not on age, gender, body mass index, duration of hypertension, or the presence of diabetes. At the final visit, 69.4% (4.3% at baseline) were controlled (<140/90 mmHg). Adverse drug reactions were observed in 2.76% of the study population; 94.25% of these adverse drug reactions were judged as nonserious events, and 31.5% of all adverse drug reactions reported were peripheral edema. Conclusion: The fixed-dose olmesartan-amlodipine combination was effective and well tolerated in an unselected population of patients in primary care practice. These results confirm prior randomized controlled trial evidence.

We present a methodology for Bayesian model choice and averaging in Gaussian directed acyclic graphs (dags). The dimension-changing move involves adding or dropping a (directed) edge from the graph. The methodology employs the results in Geiger and Heckerman and searches directly in the space of all dags. Model determination is carried out by implementing a reversible jump Markov Chain Monte Carlo sampler. To achieve this aim we rely on the concept of adjacency matrices, which provides a relatively inexpensive check for acyclicity. The performance of our procedure is illustrated by means of two simulated datasets, as well as one real dataset. [PUBLICATION ABSTRACT]

Background Venous thromboembolism (VTE) is a major health problem, with over one million events every year in Europe. However, there is a paucity of data on the current management in real life, including factors influencing treatment pathways, patient satisfaction, quality of life (QoL), and utilization of health care resources and the corresponding costs. The PREFER in VTE registry has been designed to address this and to understand medical care and needs as well as potential gaps for improvement. Methods/design The PREFER in VTE registry was a prospective, observational, multicenter study conducted in seven European countries including Austria, France Germany, Italy, Spain, Switzerland, and the UK to assess the characteristics and the management of patients with VTE, the use of health care resources, and to provide data to estimate the costs for 12 months treatment following a first-time and/or recurrent VTE diagnosed in hospitals or specialized or primary care centers. In addition, existing anticoagulant treatment patterns, patient pathways, clinical outcomes, treatment satisfaction, and health related QoL were documented. The centers were chosen to reflect the care environment in which patients with VTE are managed in each of the participating countries. Patients were eligible to be enrolled into the registry if they were at least 18 years old, had a symptomatic, objectively confirmed first time or recurrent acute VTE defined as either distal or proximal deep vein thrombosis, pulmonary embolism or both. After the baseline visit at the time of the acute VTE event, further follow-up documentations occurred at 1, 3, 6 and 12 months. Follow-up data was collected by either routinely scheduled visits or by telephone calls. Results Overall, 381 centers participated, which enrolled 3,545 patients during an observational period of 1 year. Conclusion The PREFER in VTE registry will provide valuable insights into the characteristics of patients with VTE and their acute and mid-term management, as well as into drug utilization and the use of health care resources in acute first-time and/or recurrent VTE across Europe in clinical practice.

In this paper, we compare the forecast ability of GARCH(1,1) and stochastic volatility models for interest rates. The stochastic volatility is estimated using Markov chain Monte Carlo methods. The comparison is based on daily data from 1994 to 1996 for the ten year swap rates for Deutsch Mark, Japanese Yen, and Pound Sterling. Various forecast horizons are considered. It turns out that forecasts based on stochastic volatility models are in most cases superiour to those obtained by GARCH(1,1) models.
