PERSPECTIVE ROUNDTABLE

Race in Medicine  — Genetic Variation, Social Categories, and Paths to Health Equity Watch the new Perspective Roundtable on Race in Medicine, in which experts from diverse clinical and biomedical fields discuss complex questions about race in medicine and how to build a system of equitable health for all. View the video, listen to the audio, or read the transcript. Read more articles from the Race and Medicine collection. #From:JAMA Emoji for the Medical Community—Challenges and Opportunities Debbie Lai, BA1; Jennifer 8. Lee, BA2; Shuhan He, MD3,4,5 Author Affiliations Article Information JAMA. 2021;326(9):795-796. doi:10.1001/jama.2021.8409 In 2010 emoji were officially introduced to the global lexicon as part of Unicode, the computing standards adhered to by most of the world's word processing systems. Today an emoji occupies the same status in Unicode as the Latin letter A, or Chinese character 愛, or Arabic غ, and an estimated 5 billion are used every day on Facebook and in Facebook Messenger alone.1 Emoji set curation is overseen by Unicode Consortium, a Silicon Valley–based nonprofit tasked with maintaining text standards across computers, whose members include representatives from Microsoft, Apple, and Google, among others. Anyone can propose new emoji, but each submission is reviewed via a formal and lengthy consortium process. As of 2020 there were 3521 emoji in the Unicode Standard, roughly 30 of which could be considered relevant to medicine, excluding generic body part images (eg, ear 👂, hand 🖐, leg 🦵, and foot 🦶). The current set of medical emoji is the result of ongoing, if erratic, efforts over the last 5 years. The first, introduced in 2015, were syringe 💉 and pill 💊. In 2016, efforts to expand the representation of professions brought male health worker 👨 and female health worker 👩. In 2017 Apple added emoji to better represent individuals with disabilities, collaborating with the American Council of the Blind, the Cerebral Palsy Foundation, and the National Association of the Deaf to introduce the white cane 🦯, mechanical arm 🦾, mechanical leg 🦿, and hearing aid 🦻 emoji, among others. Stethoscope 🩺, blood drop 🩸, bone 🦴, tooth 🦷, and microbe 🦠 (often used to represent viruses) followed in 2019. In 2020, 2 of the authors (D. L. and S. H.) worked with a member of the UK’s National Health Service (NHS) to win Unicode approval of the anatomical heart and anatomical lung (Figure 1). #Da:ASRM     ACADEMIA SUL-RIO-GRANDENSE DE MEDICINA      É com grande pesar que comunicamos o falecimento de nosso Membro Honorário Werner Paul Ott.

The one I believe has caused the biggest impact on us is that this pandemia has allowed us to get to know ourselves better. We have learned to fill the void that used to be satisfied by the social distractions that consumed our weekends. For me, reading was the hobby that gave me multiple benefits during the quarantine. It kept me motivated, helped me reduce the stress caused by being unable to go out of my apartment, and allowed me to sleep better by putting my mind and body at ease before getting into bed. “The more that you read, the more things you will know. The more that you learn, the more places you’ll go.” — Dr. Seuss

Brain health and its social determinants
Published:September 18, 2021DOI:https://doi.org/10.1016/S0140-6736(21)02085-7
Opinions about the relative importance of the biological and sociological causes of mental ill health have moved wildly from one extreme to another over the past 50 years. So, when Vivian Pender, the newly elected President of the American Psychiatric Association (APA), pronounced in July that “we need to be more aware of the broader context in which that illness occurred and how that context has shaped the health outcome”, cynics could be forgiven for thinking it just another swing of the pendulum. However, perhaps this time Pender—and many others, for she is not alone—has got it right./.../

#FROM THE TIME VAULT

Today in 1996: Bill Gates Aims at the Internet “For two years the rapidly expanding global computer matrix called the Internet had nagged at Gates like a low-level headache. Even as his company shipped Windows 95 last fall—an 11-million-line program that solidified Microsoft's PC hegemony—Gates worried about what lay ahead. Microsoft had long dominated the world of personal computing by providing the software that controlled the way users interacted with their machines—a program called an operating system. Microsoft's operating systems, first DOS in 1980 and then Windows 10 years later, had given the company intimidating control over PC software. And lush profits, enough to vault Gates to the top of the list of the richest Americans. But the Internet could undo all that.” (Sept. 16, 1996) READ MORE »

A sleep-like state in Hydra unravels conserved sleep mechanisms during the evolutionary development of the central nervous system

A brain isn’t necessary to sleep

© NNehring/E+/Getty Images

Even animals that are so simple that they lack brains need their sleep.

Sleep is remarkably universal, with a wide range of animals exhibiting the state, even down to insects and nematodes.

Now, a team led by researchers at Kyushu University in Japan has observed a sleep-like state in hydra — a surprising finding that given that hydra lack a central nervous system./.../

Made-up words convey across cultures

Nonsense words can be recognizable to people around the world — and not just when they’re onomatopoeic. Researchers asked English-speaking people, mostly from the United States, to make up sounds to represent a wide range of concepts, including ‘sleep’, ‘tiger’, ‘many’ and ‘good’. These vocalizations were played for volunteers in 7 countries, who spoke a total of 28 languages, and had to guess the sounds’ meanings from a list of options. Across the board, people guessed the intended meanings at rates better than chance. The findings might hint at ‘iconic’ sounds that serve as the foundations for language.

These adjustments varied by cause and case definition and were implemented using our MR-BRT modelling tool. Cardiovascular diseases—Level 2 cause Summary Cardiovascular diseases were responsible for 393 million (95% UI 368–417) DALYs in 2019, and were the leading Level 2 cause of disease burden. Overall, there were 18·6 million (17·1–19·7) deaths due to cardiovascular diseases in both sexes combined in 2019. Definition This aggregate cause incorporates death and disability resulting from 11 cardiovascular causes, led by ischaemic heart disease, stroke, and hypertensive heart disease, as well as disability due to heart failure. Both atherosclerotic and non-atherosclerotic cardiovascular diseases are included.

Fischer, 101, Who Helped Discover How Cells Talk, Dies He and a colleague identified a mechanism by which cells communicate, a Nobel-winning breakthrough that paved the way for disease-fighting drugs. #From: Understanding Evolution Understanding Evolution updates - September 2021 View this email in your browser September 8, 2021 A decade of change, a decade of Evo in the News In science, explanations like evolution are accepted or rejected based on evidence – and in that sphere, evolutionary theory has more than proven its worth. However, in the public sphere, particularly in the United States, evolutionary theory has not fared so well. Between around 1950 and 2007, surveys suggest that less than half of American adults accepted evolution. But that is changing. Researchers just announced that, over the last decade, we crossed over the halfway mark: the majority of American adults surveyed now report accepting evolution as an explanation for humans. Here, we’ll focus on the evolutionary science that accompanied this uptick in acceptance. Get the whole story here. #Da: BBC - FEB Dra. Ana Lúcia, nossa filha encontrou e recomendou.
