Abstract
Macitentan is an oral endothelin receptor antagonist for the management of pulmonary arterial hypertension (PAH). The OPsumit® USers Registry (OPUS) and the OPsumit® Historical USers cohort (OrPHeUS) medical chart review provide real‐world data for patients newly initiating macitentan. This study aims to describe the characteristics, safety profile, and clinical outcomes of PAH patients newly treated with macitentan in the combined OPUS/OrPHeUS data set. OPUS was a prospective, multicenter, long‐term, observational drug registry from April 2014 to June 2020. OrPHeUS was a retrospective, US, multicenter chart review: observation period October 2013 to March 2017. All analyses were descriptive. At registry closure in June 2020, the combined population consisted of 5654 patients, of whom 81.9% were diagnosed with PAH. For these 4626 patients, median duration of macitentan exposure observed was 14.5 (Q1 = 5.2, Q3 = 29.0) months; idiopathic PAH (54.8%) was the most common form of PAH; macitentan was initiated as monotherapy (37.9%), or as part of double (48.0%) or triple therapy (14.1%); discontinuation due to nonhepatic/hepatic adverse events occurred in 17.1%/0.3% of patients; 9.9% of patients experienced ≥1 hepatic adverse events; Kaplan–Meier estimates showed that at 1 year 59.9% (95% confidence interval: 58.3, 61.5) of patients were free from hospitalization and survival was 90.4% (89.3, 91.3). This analysis of real‐world data from the combined OPUS and OrPHeUS populations demonstrated that macitentan is well tolerated in a large, diverse population of PAH patients, with overall and hepatic safety profiles consistent with previous macitentan clinical trials.

Abstract
Abstract
Introduction
Restrictive inclusion criteria can exclude some CHD-PAH patients from clinical trials. The OPsumit® USers (OPUS) Registry and the OPsumit® Historical USers (OrPHeUS) data sets provide real-world data in PAH patients newly started on macitentan, including patients with CHD-PAH regardless of defect type.
Purpose
To describe the characteristics, safety and clinical outcomes of CHD-PAH patients newly treated with macitentan.
Methods
OPUS is a prospective, US, multicentre, observational drug registry ongoing since April 2014. OrPHeUS was a retrospective, US, multicentre chart review; observation period Oct 2013–Mar 2017. This analysis reports information on CHD-PAH patients in the combined OPUS/OrPHeUS data set, descriptively compared with idiopathic/heritable PAH (I/HPAH) patients.
Results
As of Sept 2019, there were 4268 PAH patients with follow-up data, of whom 264 (6%) had CHD-PAH and 2396 (56%) had I/HPAH. For CHD-PAH and I/HPAH patients respectively at macitentan initiation: median age (Q1, Q3) was 48 (36, 62) and 65 (53, 73) years; 199 (75%) and 1748 (73%) were female; 67/114 (59%) and 802/1301 (62%) were WHO functional class III/IV; median (Q1, Q3) 6-minute walk distances were 350 (274, 420) and 289 (195, 375) m for the 82 and 840 patients with measurements; median (Q1, Q3) time from PAH diagnosis to macitentan initiation was 37.3 (4.5, 113.1) and 7.4 (1.4, 38.3) months; and 99 (38%) and 1056 (44%) initiated macitentan as monotherapy. The number of patients with ≥1 hepatic adverse event (HAE) was similar for CHD-PAH and I/HPAH (22 [8%] and 184 [8%]), as were the adverse event (AE) profiles (collected from OPUS only). Exposure, discontinuations, outcomes and most common AEs are shown in the table.
Conclusions
In general, compared with I/HPAH patients, CHD-PAH patients were younger and a greater proportion had prevalent disease than I/HPAH patients. Safety and outcomes were similar between the groups.

Abstract
Abstract
Introduction
PAH impacts right ventricular (RV) structure and function but also leads to changes in the LV due to RV/LV interaction and underfilling. REPAIR, the first PAH study to use a primary endpoint assessed by cardiac MRI (cMRI), reported that RV stroke volume (RVSV) increased by 12 mL and pulmonary vascular resistance (PVR) decreased by 38% from baseline (BL) to Week 26 with macitentan.
Purpose
To assess the effect of macitentan on LV function in patients with PAH.
Methods
REPAIR (NCT02310672) was a 52-week, multicentre, open-label, single-arm, phase 4 study assessing the effect of macitentan primarily on RV structure and function, determined by cMRI and right heart catheterisation. Macitentan 10 mg was initiated in treatment-naïve patients, in patients receiving stable background phosphodiesterase type-5 inhibitor (PDE5i) at BL, or in initial combination with PDE5i. Exploratory LV endpoints were assessed by cMRI at Weeks 26 and 52. Safety was assessed up to end of study treatment +30 days in all patients who received ≥1 dose of macitentan (N=87). Patients with BL and Week 26 assessments for both PVR and RVSV were included in the modified Full Analysis Set (mFAS; N=71).
Results
In the mFAS, 57 (80%) patients were female. At BL, median age was 45 years; median (Q1, Q3) six-minute walk distance was 395 (323, 483) m; 48%/51% of patients were WHO functional class II/III; 59% had idiopathic PAH. Compared to BL, at Weeks 26 and 52 there were significant changes in LV cMRI parameters (table). The most common AEs were peripheral oedema (22%), headache (21%) and dizziness (14%).
Conclusions
Macitentan led to improvements in LV mass, volume and function, including clinically-relevant increases in LV stroke volume, at both 26 and 52 weeks in patients with PAH. Safety was consistent with other macitentan clinical trial data.

Abstract
Abstract
Introduction
Guidelines for the management of PAH recommend combination therapy for most patients, yet real-world data on treatment patterns in PAH are limited.
Purpose
To describe the characteristics, safety and clinical outcomes of PAH patients newly treated with double combination therapy with macitentan and PDE5i in the OPsumit® USers (OPUS) Registry and the OPsumit® Historical USers cohort study (OrPHeUS) combined dataset.
Methods
OPUS is a prospective, US, multicentre, observational drug registry (NCT02126943) ongoing since April 2014. OrPHeUS was a retrospective, US, multicentre chart review (NCT03197688); Oct 2013–Mar 2017. This cohort included patients initiating combination therapy with macitentan and a PDE5i (in any order) ≤60 days apart. Baseline was defined as the start date of the second therapy (i.e., start of combination therapy). Patient characteristics at baseline, changes in 6-minute walk distance (6MWD) and WHO functional class (FC) from baseline to follow-up, safety and outcomes are described.
Results
Of the 4428 OPUS/OrPHeUS PAH patients initiating macitentan, 2490 received this in combination with a PDE5i; of these patients, 740 (29.7%) initiated macitentan and a PDE5i concurrently (≤60 days apart). Data on disease duration was recorded in 729 patients at baseline; of these, 588 (80.7%) patients were incident (≤6 months since diagnosis) and 141 (19.3%) were prevalent (>6 months since diagnosis); median time from diagnosis to start of combination therapy of was 1.4 (Q1=0.6, Q3=3.6) months. At baseline, median age was 60 (Q1=49, Q3=70) years and 73.6% of patients were female. Mean baseline 6MWD was 264.5 (SD=119.8) m, recorded in 240 (32.4%) patients. WHO FC was recorded at baseline for 347 (46.9%) patients; 263 (75.8%) were in FC III/IV. Median combination therapy exposure was 10.2 (Q1=3.4, Q3=21.8) months, with 58.8% of patients ongoing at data cut. Changes from baseline to follow up in FC and 6MWD are shown in the figure. There was ≥1 adverse event (AE) reported in 455 (61.5%) patients and ≥1 hepatic AE (HAE) in 76 (10.3%) patients. In total, 232 (31.4%) patients discontinued macitentan; 122 (16.5%) due to AEs, 4 (0.5%) due to HAEs, 98 (13.2%) not due to an AE/HAE, and 8 (1.1%) for unknown reasons. Of the 305 patients who discontinued combination therapy, 137 (18.5%) discontinued macitentan only, 73 (9.9%) discontinued PDE5i only, and 95 (12.8%) discontinued both drugs at the same time. Kaplan-Meier estimates (95% CI) showed that 60.7% (56.4, 64.8) of patients were free from hospitalisation and 88.7% (85.7, 91.1) were alive at 12 months.
Conclusions
In this real-world setting, less than one third of patients treated with macitentan received initial oral combination therapy, despite current expert consensus favouring such therapeutic approaches. Patients initiating macitentan+PDE5i ≤60 days apart had improved 6MWD and WHO FC from baseline to follow-up.

Abstract
BACKGROUND Anticoagulant prophylaxis substantially reduces the risk of venous thromboembolism (VTE) after major orthopedic surgery. The direct factor Xa inhibitor YM150 is currently under investigation for the prevention of VTE, stroke and ischemic vascular events in patients after orthopedic surgery, with atrial fibrillation and with acute coronary syndrome, respectively. OBJECTIVES To investigate the efficacy and safety of YM150 for the prevention of VTE following elective total hip arthroplasty. PATIENTS/METHODS Patients were randomized to postoperative, once-daily, oral YM150 (5, 10, 30, 60 or 120 mg) (double-blind) or preoperative subcutaneous (open label) enoxaparin (40 mg) for 5 weeks. The primary efficacy endpoint comprised VTE diagnosed by mandatory bilateral venography or verified symptomatic deep vein thrombosis (DVT) plus all deaths up to 9 days after surgery. The primary safety outcome was major bleeding up to 9 days after surgery. RESULTS Primary efficacy endpoint: of 1017 patients randomized, 960 patients were evaluable for safety and 729 patients for efficacy. A dose-related decrease in VTE incidence from YM150 5 to 60 mg (P = 0.0005) and from 5 to 120 mg (P = 0.0002) was found. The VTE incidence was 27.4%, 31.7%, 19.3%, 13.3% and 14.5% for 5, 10, 30, 60 and 120 mg YM150, respectively, and 18.9% for enoxaparin. Primary safety endpoint: there was one major bleed with YM150 (60 mg) and one with enoxaparin. CONCLUSIONS The oral direct FXa inhibitor YM150 demonstrated a significant dose response regarding efficacy. Doses from 30 to 120 mg had comparable efficacy to enoxaparin, without compromising safety regarding major bleeding events.

Abstract
Large Near-Earth-Asteroids have played a role in modifying the character of the surface geology of the Earth over long time scales through impacts. Recent modeling of the disruption of large meteoroids during atmospheric flight has emphasized the dramatic effects that smaller objects may also have on the Earth's surface. However, comparison of these models with observations has not been possible until now. Peekskill is only the fourth meteorite to have been recovered for which detailed and precise data exist on the meteoroid atmospheric trajectory and orbit. Consequently, there are few constraints on the position of meteorites in the solar system before impact on Earth. In this paper, the preliminary analysis based on 4 from all 15 video recordings of the fireball of October 9, 1992 which resulted in the fall of a 12.4 kg ordinary chondrite (H6 monomict breccia) in Peekskill, New York, will be given. Preliminary computations revealed that the Peekskill fireball was an Earth-grazing event, the third such case with precise data available. The body with an initial mass of the order of 10(4) kg was in a pre-collision orbit with a = 1.5 AU, an aphelion of slightly over 2 AU and an inclination of 5 degrees. The no-atmosphere geocentric trajectory would have lead to a perigee of 22 km above the Earth's surface, but the body never reached this point due to tremendous fragmentation and other forms of ablation. The dark flight of the recovered meteorite started from a height of 30 km, when the velocity dropped below 3 km/s, and the body continued 50 km more without ablation, until it hit a parked car in Peekskill, New York with a velocity of about 80 m/s. Our observations are the first video records of a bright fireball and the first motion pictures of a fireball with an associated meteorite fall.

Abstract
Three adult men were fed 204 Pb - a rare, stable isotope of lead - daily for about 100 days. Simultaneous blood and facial hair measurements of this tracer and of total lead concentrations were made by mass spectrometric isotope dilution analysis. Although the blood showed an immediate response to the intake of the tracer, the facial hair showed a more gradual response and a delay of approximately 35 days. Since the pattern of appearance of lead in hair does not appear to represent a simple time delay of blood lead concentration, the existence of a physiological pool of lead fed by the blood and giving rise to the content in hair is suggested. Hair lead values should, therefore, be interpreted as the integral of the blood lead values over the mean life of this intermediate pool - about 100 days.
