About the Study: After Dobbs v Jackson Women’s Health Organization, out-of-state travel to North Carolina for abortion care increased, particularly from more restrictive Southeastern states. Patients also presented at later gestational durations and traveled farther for care, indicating increased logistical barriers after policy changes.

About the Study: In this cross-sectional study, the Brexit referendum’s policy uncertainty produced a sustained decline in EU-origin health care worker immigration, partially offset by recruitment from non-EU countries. This substitution did not prevent increases in physician vacancies and persistent nursing shortfalls, underscoring the sensitivity of health workforce supply to migration policy. Policymakers considering similar restrictions should account for anticipatory effects, substitution dynamics, and potential consequences for global health equity.

The United Kingdom's vote to leave the European Union (EU) was associated with major changes in health care worker migration and worsening physician shortages in England, according to a new study published in JAMA Health Forum.

Europe’s rules for proving environmental performance of battery technologies could reshape sustainability regulation far beyond the European Union (EU), researchers report in a Policy Article. However, as regionally based requirements spread across global industries, differences in data, measurement and verification systems can complicate their application. Sustainability in the global battery industry depends not only on cleaner technologies but also on how environmental claims are documented and verified. The European Union’s Batteries Regulation establishes detailed requirements for tracking a battery’s life-cycle greenhouse-gas emissions, material circularity, and responsible sourcing. This creates a new dimension of the so-called “Brussels Effect,” in which EU standards can become de facto global norms because companies worldwide must meet them to access the European market. Here, Yanan Liang and colleagues examine the EU Battery Reregulation and focus on how its evidence requirements spread internationally. The spread happens through compliance-driven diffusion along supply chains and because international standards organizations and foreign regulators voluntarily adopt similar approaches. Liang et al. found that these processes can improve transparency and credibility but also create challenges when region-specific measurement and verification rules are applied to global production and data infrastructures. To address this, the authors propose a phased approach involving methodological reconciliation, flexible and risk-based verification, and shared governance of datasets.
