Almost 40 years ago, the discovery of the vasoactive neuropeptide calcitonin gene-related peptide (CGRP) and its role in migraine pathophysiology ushered in a new era in migraine treatment. Since 2018, monoclonal antibodies (mAbs) targeting the CGRP pathway are available for migraine prevention. The approval of these drugs marks a pioneering development, as they are the first pharmacological agents specifically tailored for migraine prevention. Introduction of these agents contrasts the historical reliance on traditional preventive medications initially formulated for other indications and later repurposed for migraine therapy. Although the emergence of evidence on the efficacy and safety of CGRP-targeted mAbs has raised the bar for treatment success in migraine, their efficacy in other headache entities, such as cluster headache, is low to moderate. Small-molecule CGRP receptor antagonists called gepants have also been proven to be effective both as acute and preventive migraine treatments. Furthermore, these agents have bridged the traditional categories of acute and preventive treatment strategies. Short-term prevention and treatment during the prodromal phase of migraine represent emerging strategies enabling clinicians to develop treatment approaches designed to meet changing patient needs; however, these strategies still require more formal evidence. Although solid data have been gathered, further research concerning the efficacy and long-term safety of drugs targeting the CGRP pathway and robust pharmacoeconomic evaluations are needed. Finally, randomised withdrawal and switching studies would facilitate the formulation of evidence-based guidance for the discontinuation of and switching between drugs targeting the CGRP pathway.

Despite a substantial reduction in the use of solid fuels for cooking worldwide, exposure to household air pollution (HAP) remains a leading global risk factor, contributing considerably to the burden of disease. We present a comprehensive analysis of spatial patterns and temporal trends in exposure and attributable disease from 1990 to 2021, featuring substantial methodological updates compared with previous iterations of the Global Burden of Diseases, Injuries, and Risk Factors Study, including improved exposure estimations accounting for specific fuel types.

Human African trypanosomiasis or sleeping sickness is caused by infection with Trypanosoma brucei gambiense or Trypanosoma brucei rhodesiense parasites, which are transmitted by tsetse flies in sub-Saharan Africa. Control of human African trypanosomiasis is based on case detection, treatment, and vector control. In the past decade, simple rapid diagnostic tests were introduced for gambiense human African trypanosomiasis, facilitating screening in primary health-care facilities. A new oral drug, fexinidazole, became the first-line treatment for gambiense human African trypanosomiasis without severe meningo-encephalitic disease, as well as for rhodesiense human African trypanosomiasis. Medical interventions, in some areas combined with tiny target-based vector control, have substantially reduced human African trypanosomiasis incidence, despite temporary disruptions to health-care systems. The elimination of human African trypanosomiasis as a public health problem has been achieved, and elimination of gambiense human African trypanosomiasis transmission is now targeted for 2030. Improved diagnostics and drugs, continued involvement of populations at risk of disease, health staff, national authorities, and partners and donors all contribute to achieve this goal.
