The state of adolescent menstrual health in low- and middle-income countries and suggestions for future action and research

In recognition of the opportunity created by the increasing attention to menstrual health at global, regional, and national levels, the World Health Organization’s Department of Sexual and Reproductive Health and Research and the UNDP-UNFPA-UNICEF-WHO-World Bank Special Programme of Research, Development and Research Training in Human Reproduction convened a global research collaborative meeting on menstrual health in adolescents in August 2018. Experts considered nine domains of menstrual health (awareness and understanding; stigma, norms, and socio-cultural practices; menstrual products; water and sanitation; disposal; empathy and support; clinical care; integration with other programmes; and financing) and answered the following five questions: (1) What is the current situation? (2) What are the factors contributing to this situation? (3) What should the status of this domain of adolescent menstrual health be in 10 years? (4) What actions are needed to achieve these goals? (5) What research is needed to achieve these goals? This commentary summarizes the consensus reached in relation to these questions during the expert consultation. In doing so, it describes the state of adolescent menstrual health in low- and middle-income countries and sets out suggestions for action and research that could contribute to meeting the holistic menstrual health needs of adolescent girls and others who menstruate worldwide

The genetic architecture of the human cerebral cortex

The cerebral cortex underlies our complex cognitive capabilities, yet little is known about the specific genetic loci that influence human cortical structure. To identify genetic variants that affect cortical structure, we conducted a genome-wide association meta-analysis of brain magnetic resonance imaging data from 51,665 individuals. We analyzed the surface area and average thickness of the whole cortex and 34 regions with known functional specializations. We identified 199 significant loci and found significant enrichment for loci influencing total surface area within regulatory elements that are active during prenatal cortical development, supporting the radial unit hypothesis. Loci that affect regional surface area cluster near genes in Wnt signaling pathways, which influence progenitor expansion and areal identity. Variation in cortical structure is genetically correlated with cognitive function, Parkinson's disease, insomnia, depression, neuroticism, and attention deficit hyperactivity disorder
