B - PLANO DE ENSINO:

Súmula: O curso vai apresentar os desafios da mudança climática e de saúde confrontado por populações urbanas, a seguir vai identificar políticas publicas que respondem a estas necessidades, através de criar resiliência aos efeitos da mudança climática (como as enchentes); mitigar gases de efeito serra (GES); promover a saúde e bem-estar assim como prevenir doenças mais frequentes (como a enfermidades não transmissíveis ou vetoriais). Políticas de transporte, habitação, energia, gestão dos resíduos, alimentação e agricultura e planejamento urbano serão analisadas por estes prismas. Metodologias que servem para identificar como políticas publicas nestes setores podem prevenir os impactos do clima e ao mesmo tempo prevenir causa importantes de doenças, serão apresentadas, incluindo instrumentos para avaliação de impactos na saúde (AIS), que integra métodos qualitativos e quantitativos, e elaboração de cenários do que esperar como resultado da implementação dos AIS. Também se vai trabalhar questões de desinformação e instrumentos para confrontá-la. O curso inclui exercícios práticos, durante o período de aula, com utilização de AIS na análise de estudos de caso que serão identificados junto com os alunos, referentes a políticas que possam ser implementadas na região. Professores convidados de universidades no Brasil e no exterior apresentarão (em Português) sua experiencia com mecanismos de contabilidade social em saúde urbana, confrontar desinformação, e avaliação de politicas publicas urbanas.

Calling all global health innovators! Each year, the Roux Prize recognizes an individual or organization working toward making the world a healthier place. Nominations for the 2025 Roux Prize are now open until March 7. Key findings from five-paper series on state of US health IHME Director Dr. Chris Murray recently gave a seminar on the five-paper series from IHME published this fall in The Lancet’s special issue on the state of health in the US. The seminar expanded on study highlights from each paper and their implications for future policy action.  Watch the seminar Our podcast, Global Health Insights, is a collection of discussions with IHME experts on recent publications, trending topics in the public health space, and health challenges around the globe. These conversations provide insight on how new research can guide policy decisions, inform policymakers, and serve as a catalyst for improving health outcomes.

#  AI Predicts Autoimmune Disease Progression with New Genetic Tool - Neuroscience News

# https://neurosciencenews.com/sleep-glympthatic-norepinepherine-28332/

Summary: Deep sleep may clear the brain of toxic waste via a process driven by norepinephrine, a molecule that creates rhythmic blood vessel contractions. This “brainwashing” system, part of the glymphatic system, helps remove harmful proteins linked to neurological disorders.

Researchers found that sleep aids like zolpidem might impair this process by reducing norepinephrine waves, potentially disrupting brain waste clearance. The study underscores the importance of restorative sleep and its role in preventing cognitive decline.
Key Facts

• Glymphatic Function: Deep sleep facilitates waste removal in the brain, clearing harmful proteins through the glymphatic system.

• Norepinephrine Waves: During deep sleep, norepinephrine drives rhythmic blood vessel contractions, propelling brain fluid to remove waste.

• Sleep Aid Impact: Sleep medications like zolpidem may reduce norepinephrine waves, disrupting the brain’s cleaning process by 30%.
