PFAS Contamination in Europe: Generating Knowledge and Mapping Known and Likely Contamination with "Expert-Reviewed" Journalism.

While the extent of environmental contamination by per- and polyfluoroalkyl substances (PFAS) has mobilized considerable efforts around the globe in recent years, publicly available data on PFAS in Europe were very limited. In an unprecedented experiment of "expert-reviewed journalism" involving 29 journalists and seven scientific advisers, a cross-border collaborative project, the "Forever Pollution Project" (FPP), drew on both scientific methods and investigative journalism techniques such as open-source intelligence (OSINT) and freedom of information (FOI) requests to map contamination across Europe, making public data that previously had existed as "unseen science". The FPP identified 22,934 known contamination sites, including 20 PFAS manufacturing facilities, and 21,426 "presumptive contamination sites", including 13,745 sites presumably contaminated with fluorinated aqueous film-forming foam (AFFF) discharge, 2911 industrial facilities, and 4752 sites related to PFAS-containing waste. Additionally, the FPP identified 231 "known PFAS users", a new category for sites with an intermediate level of evidence of PFAS use and considered likely to be contamination sources. However, the true extent of contamination in Europe remains significantly underestimated due to a lack of comprehensive geolocation, sampling, and publicly available data. This model of knowledge production and dissemination offers lessons for researchers, policymakers, and journalists about cross-field collaborations and data transparency.

Age-Related Differences in the Presentation, Management, and Clinical Outcomes of 100,000 Patients With Venous Thromboembolism in the RIETE Registry.

INTRODUCTION: Although older adults represent a significant proportion of patients with venous thromboembolism (VTE), the data on the impact of age-related differences in the clinical presentation, management, and outcomes of VTE are scarce. METHODS: We analyzed data from the RIETE registry database, an ongoing global observational registry of patients with objectively confirmed VTE, to compare patient characteristics, clinical presentation, treatments, and outcomes between elderly (≥70 years) vs. non-elderly (<70 years) patients. RESULTS: From January 2001 to March 2021, 100,000 adult patients were enrolled in RIETE. Elderly patients (47.9%) were more frequently women (58.2% vs. 43.5%), more likely had unprovoked VTE (50.5% vs. 45.1%) and most often presented with severe renal failure (10.2% vs. 1.2%) and acute pulmonary embolism (PE) (vs. deep vein thrombosis) (54.3% vs. 44.5%) compared to non-elderly patients (p<0.001 for all comparisons). For the PE subgroup, elderly patients more frequently had non-low risk PE (78.9% vs. 50.7%; p<0.001), respiratory failure (33.9% vs. 21.8%; p<0.001) and myocardial injury (40.0% vs. 26.2%; p<0.001) compared to non-elderly patients. Thrombolysis (0.9% vs. 1.7%; p<0.001) and direct oral anticoagulants (8.8% vs. 11.8%; p<0.001) were less frequently administered to elderly patients. Elderly patients showed a significantly higher 30-day all-cause mortality (adjusted odds ratio [OR] 1.36, 95%CI: 1.22-1.52) and major bleeding (OR, 2.08; 95%CI, 1.85-2.33), but a lower risk of 30-day VTE recurrences (OR, 0.62, 95%CI, 0.54-0.71). CONCLUSIONS: Compared with non-elderly patients, elderly patients had a different VTE clinical profile. Advanced therapies were less frequently used in older patients. Age was an independent predictor of mortality.

Residual ST-segment elevation to predict long-term clinical and CMR-derived outcomes in STEMI.

Residual ST-segment elevation after ST-segment elevation myocardial infarction (STEMI) has traditionally been considered a predictor of left ventricular (LV) dysfunction and ventricular aneurism. However, the implications in terms of long-term prognosis and cardiac magnetic resonance (CMR)-derived structural consequences are unclear. A total of 488 reperfused STEMI patients were prospectively included. The number of Q wave leads with residual ST-segment elevation > 1 mm (Q-STE) at pre-discharge ECG was assessed. LV ejection fraction (LVEF, %) and infarct size (IS, % of LV mass) were quantified in 319 patients at 6-month CMR. Major adverse cardiac events (MACE) were defined as all-cause death and/or re-admission for acute heart failure (HF), whichever occurred first. During a mean follow-up of 6.1 years, 92 MACE (18.9%), 39 deaths and 53 HF were recorded. After adjustment for baseline characteristics, Q-STE (per lead with > 1 mm) was independently associated with a higher risk of long-term MACE (HR 1.24 [1.07-1.44] per lead, p = 0.004), reduced (< 40%) LVEF (HR 1.36 [1.02-1.82] per lead, p = 0.04) and large (> 30% of LV mass) IS (HR 1.43 [1.11-1.85] per lead, p = 0.006) at 6-month CMR. Patients with Q-STE ≥ 2 leads (n = 172, 35.2%) displayed lower MACE-free survival, more depressed LVEF, and larger IS at 6-month CMR (p < 0.001 for all comparisons). Residual ST-segment elevation after STEMI represents a universally available tool that predicts worse long-term clinical and CMR-derived structural outcomes.

Sublingual versus vaginal misoprostol (400 microg) for cervical priming in first-trimester abortion: a randomized trial.

OBJECTIVE: Our objective was to compare the sublingual administration and the vaginal administration of misoprostol for cervical priming before first-trimester surgical abortion. DESIGN: We used an open, multicenter, randomized trial. LOCATIONS: We conducted the study in four clinics (in Valencia, Castelló, Murcia and Murcia Capital) in Spain. PARTICIPANTS: A total of 1424 healthy pregnant women with amenorrhea of
