onism. These data demonstrate that PAR antagonists may be a useful addition to DAPT in some patients and further demonstrate the utility of in vitro models of occlusive thrombosis.Hemophilia A and B are hereditary bleeding disorders, characterized by factor VIII or IX deficiencies, respectively. For many decades, prophylaxis with coagulation factor concentrates (replacement therapy) was the standard-of-care approach in hemophilia. Since the 1950s, when prophylaxis started, factor concentrates have been improved with virus inactivation and molecule modification to extend its half-life. The past years have brought an intense revolution in hemophilia care, with the development of nonfactor therapy and gene therapy. Emicizumab is the first and only nonreplacement agent to be licensed for prophylaxis in people with hemophilia A, and real-world data show similar efficacy and safety from the pivotal studies. Other nonreplacement agents and gene therapy have ongoing studies with promising results. Innovative approaches, like subcutaneous factor VIII and lipid nanoparticles, are in the preclinical phase. These novel agents, such as extended half-life concentrates and emicizumab, have been available in resource-constrained countries through the constant efforts of the World Federation of Haemophilia Humanitarian Aid Program. Despite the wide range of new approaches and therapies, the main challenge remains the same to guarantee treatment for all. In this article, we discuss the evolution of hemophilia care, global access to hemophilia treatment, and the current and future strategies that are now under development. Finally, we summarize relevant new data on this topic presented at the ISTH 2021 virtual congress.A number of papers by Young and collaborators have criticized epidemiological studies and meta-analyses of air pollution hazards using a graphical method that the authors call a P value plot, claiming to find zero effects, heterogeneity, and P hacking. However, the P value plot method has not been validated in a peer-reviewed publication. The aim of this study was to investigate the statistical and evidentiary properties of this method.
A simulation was developed to create studies and meta-analyses with known real effects
δ
, integrating two quantifiable conceptions of evidence from the philosophy of science literature. The simulation and analysis is publicly available and automatically reproduced.
In this simulation, the plot did not provide evidence for heterogeneity or
hacking with respect to any condition. Under the right conditions, the plot can provide evidence of zero effects; but these conditions are not satisfied in any actual use by Young and collaborators.
The
value plot does not provide evidence to support the skeptical claims about air pollution hazards made by Young and collaborators.

Gestational exposure to these endocrine- and metabolism-disrupting chemicals may influence child cardiometabolic health.
We measured the serum concentration of DDT and dichlorodiphenyldichloroethylene (DDE) and urinary concentration of pyrethroid metabolites (
-DBCA,
-DCCA,
-DCCA, 3-PBA) in peripartum samples collected between August 2012 and December 2013 from 637 women participating in the Venda Health Examination of Mothers, Babies and their Environment (VHEMBE), a birth cohort study based in Limpopo, South Africa. We applied marginal structural models to estimate the relationship between biomarker concentrations and child-size (height and weight), adiposity (body mass index [BMI], body fat percentage, waist circumference) and blood pressure at 5 years of age.
Maternal concentrations of all four pyrethroid metabolites were associated with lower adiposity including reduced BMI z-scores, smaller waist circumferences, and decreased body fat percentages. Reductions in BMI z-score were observed only among children of mothers with sufficient energy intake during pregnancy (β
-
=-0.4, 95% confidence interval (CI) = -0.7,-0.1; p
=0.03 and 0.04, respectively) but there was no evidence of effect modification for the other measures of adiposity. Maternal
-DDT concentrations were associated with a reduction in body fat percentage (β = -0.4%, 95% CI = -0.8,-0.0).
Gestational exposure to pyrethroids may reduce adiposity in children at 5 years of age.

It is unknown whether evidence of metabolic disruption associated with air pollution is identifiable at birth. We examined exposure to prenatal ambient air pollution and cord blood cardiometabolic biomarkers among 812 mother-infant pairs in the Healthy Start study.
Using inverse-distance-weighted interpolation of ambient concentrations obtained from stationary monitors, we estimated daily particulate matter ≤2.5 micrometers (PM
) and ozone (O
) concentrations at participant residences. Daily estimates were averaged by trimester, full-pregnancy, and the 7 and 30 days prior to delivery. Associations of air pollution with the following cord blood biomarkers were estimated via multivariable linear regression glucose, insulin, glucose/insulin ratio (GIR), leptin, high-density lipoprotein (HDL) cholesterol, non-HDL cholesterol, free fatty acids, and triglycerides.
In this Denver-based cohort, PM

We used data from 253 mother-child pairs in Cincinnati, OH (the Health Outcomes and Measures of the Environment study, 2003-2006). We measured urinary concentrations of 11 phthalate metabolites twice during pregnancy and up to six times in childhood. We evaluated children's cognitive abilities at ages 5 and 8 years. Using mediation models, we quantified covariate-adjusted direct and indirect effects of race on children's Full-Scale Intelligence Quotient (IQ) scores for individual phthalate metabolite concentrations during gestation and childhood.
Average IQ scores among Black children (n = 90) were 7.0 points lower (95% confidence interval [CI] = -12, -1.8) than among White children (n = 145) after adjustment for socioeconomic factors. Urinary monobenzyl phthalate and monoethyl phthalate (MEP) concentrations during gestation and childhood were higher among Black than White children. STAT5-IN-1 concentration We did not observe evidence that phthalate concentrations mediated the race-IQ association, with the exception of MEP. Childhood MEP concentrations partially mediated the race-IQ association. For instance, each 10-fold increase in MEP concentrations at age 2 years contributed to a 1.9-point disparity in IQ scores between Black and White children (95% CI = -4.7, 0.7). Other phthalate metabolite concentrations during pregnancy or childhood did not mediate the race-IQ association.
Despite observing racial disparities in exposure to some phthalates and IQ, we found little evidence that phthalates contribute to IQ disparities.

Neighborhood walkability and greenness may also be associated with CVD, but there is limited evidence on their joint or interacting effects with PM2.5.
Cox proportional hazard models were used to estimate the risk of CVD mortality among adults with a history of acute myocardial infarction and/or stroke living in Northern California. We assessed the independent and joint effects of walkability, greenness (Normalized Differentiated Vegetation Index [NDVI]), and PM
at residential addresses, controlling for age, sex, race/ethnicity, comorbidities, BMI, smoking, revascularization, medications, and socioeconomic status.
Greenness had a nonlinear association with CVD mortality (
= 0.038), with notably protective effects (HR = 0.87 [95% confidence interval CI = 0.78, 0.97]) at higher greenness levels (NDVI ≥ 0.3) and moderate attenuation after adjusting for PM
(HR = 0.92 [95% CI = 0.82, 1.03]) per 0.1 increase in NDVI.In population research, exposure to environmental contaminants is often indirectly assessed by linking residence to geocoded databases of environmental exposures. We explored the potential for misclassification of residence-based environmental exposure as a result of not accounting for the workplace environments of employed pregnant women using data from a National Birth Defects Prevention Study (NBDPS) analysis of drinking water haloacetic acids and hypospadias.
The original analysis used NBDPS data from women with haloacetic acid exposure information in eight states who delivered an infant with second- or third-degree hypospadias (cases) or a male infant without a birth defect (controls) between 2000 and 2005. In this bias analysis, we used a uniform distribution to randomly select 11%-14% of employed women that were assumed to change municipal water systems between home and work and imputed new contaminant exposures for tap water beverages consumed at work among the selected women using resampled values from the control population. Multivariable logistic regression was used to estimate the association between hypospadias and haloacetic acid ingestion with the same covariates and exposure cut-points as the original study. We repeated this process across 10,000 iterations and then completed a sensitivity analysis of an additional 10,000 iterations where we expanded the uniform distribution (i.e., 0%, 28%).
In both simulations, the average results of the 10,000 iterations were nearly identical to those of the initial study.
Our results suggest that household estimates may be sufficient proxies for worksite exposures to haloacetic acids in tap water.

In this study, we characterized long-term exposure to six major PM2.5 components and their individual association with disease aggravation in ALS.
We leveraged 15 years of data from the New York Department of Health Statewide Planning and Research Cooperative System (2000-2014) to calculate annual ALS first hospitalizations in New York State. We used the first hospital admission as a surrogate of disease aggravation and a prediction model to estimate population-weighted annual black carbon, organic matter (OM), nitrate, sulfate, sea salt, and soil concentrations at the county level. We used a multi-pollutant mixed quasi-Poisson model with county-specific random intercepts to estimate rate ratios (RR) of 1-year exposure to each PM
component and disease aggravation in ALS, adjusting for potential confounders.
We observed 5,655 first ALS-related hospitalizations. The annual average hospitalization count per county was 6.
