Family socioeconomic status, body mass index, and either personal or parental smoking during childhood predicted the likelihood of achieving ideal cardiovascular health as an adult, researchers found.
Better socioeconomic status and lower BMI were significantly associated with having ideal cardiovascular health 2 to 3 decades later in three cohort studies conducted in Finland, Australia, and the U.S. (P<0 .01="" according="" and="" bm="" both="" colleagues.="" finland="" for="" in="" laitinen="" of="" p="" the="" to="" tomi="" turku="" university="" variables="">

Aging

Why Older People Tend to Be Poor Decision-Makers

It’s not just dementia and cognitive decline that makes people more uncertain with age; changes in rationality and the way the elderly evaluate risk could explain why they are more likely to make the wrong decisions affecting everything from their health to their finances.
While numerous studies have documented a drop in cognitive function with age, there isn’t solid data to explain what drives this decline in decision-making, particularly in the face of uncertainty. But according to the latest research, poor choices made by the elderly can’t be attributed to their lack of math skills or a fear of financial losses. In the study, people over age 65 tended to be inconsistent when making decisions where there was one obviously correct answer, such as choosing between a definite win of $5 and a lottery with indefinite odds of winning the same amount./.../

Psychotherapy

Psychotherapy’s Image Problem


PROVIDENCE, R.I. — PSYCHOTHERAPY is in decline. In the United States, from 1998 to 2007, the number of patients in outpatient mental health facilities receiving psychotherapy alone fell by 34 percent, while the number receiving medication alone increased by 23 percent.

This is not necessarily for a lack of interest. A recent analysis of 33 studies found that patients expressed a three-times-greater preference for psychotherapy over medications.
As well they should: for patients with the most common conditions, like depression and anxiety, empirically supported psychotherapies — that is, those shown to be safe and effective in randomized controlled trials — are indeed the best treatments of first choice. Medications, because of their potential side effects, should in most cases be considered only if therapy either doesn’t work well or if the patient isn’t willing to try counseling.
So what explains the gap between what people might prefer and benefit from, and what they get?/.../

Singularity

Technological Singularity

Technological singularity

From Wikipedia, the free encyclopedia
Jump to: navigationsearch
The technological singularity, or simply the singularity, is a theoretical moment in time when artificial intelligence will have progressed to the point of a greater-than-human intelligence that will "radically change human civilization, and perhaps even human nature itself."[1] Since the capabilities of such an intelligence may be difficult for an unaided human mind to comprehend, the technological singularity is often seen as an occurrence (akin to a gravitational singularity) beyond which—from the perspective of the present—the future course of human history is unpredictable or even unfathomable.
The first use of the term "singularity" in this context was by mathematician John von Neumann. Neumann in the mid-1950s spoke of "ever accelerating progress of technology and changes in the mode of human life, which gives the appearance of approaching some essential singularity in the history of the race beyond which human affairs, as we know them, could not continue".[2] The term was popularized by science fiction writerVernor Vinge, who argues that artificial intelligencehuman biological enhancement, orbrain-computer interfaces could be possible causes of the singularity.[3] Futurist Ray Kurzweil cited von Neumann's use of the term in a foreword to von Neumann's classicThe Computer and the Brain./.../

Wisdom from a MacArthur Genius: Psychologist Angela Duckworth on Why Grit, Not IQ, Predicts Success

by 
“Character is at least as important as intellect.”
Creative history brims with embodied examples of why the secret of genius is doggedness rather than “god”-given talent, from the case of young Mozart’s upbringing to E. B. White’s wisdom on writing to Chuck Close’s assertion about art toTchaikovsky’s conviction about composition toNeil Gaiman’s advice to aspiring writers. But it takes a brilliant scholar of the psychology of achievement to empirically prove these creative intuitions: Math-teacher-turned-psychologistAngela Duckworth, who began her graduate studies under positive psychology godfather Martin Seligman at my alma mater, the University of Pennsylvania, has done more than anyone for advancing our understanding of how self-control and grit — the relentless work ethic of sustaining your commitments toward a long-term goal — impact success. So how heartening to hear that Duckworth is the recipient of a 2013 MacArthur “genius” grant for her extraordinary endeavors, the implications of which span from education to employment to human happiness./.../

brain activity in deep coma

Researchers observe never-before-detected brain activity in deep coma

Flat line and Nu-complex signals (credit: Daniel Kroeger et al./PLoS ONE)
University of Montreal researchers have found brain activity that kicks in after a patient’s EEG shows an isoelectric (“flat line”) EEG, according to their paper in PLoS ONE (open access).
The flatline EEG (brainwave) pattern is usually recorded during very deep coma and is considered to be one of the limit points in establishing brain death. In particular clinical conditions, it is accepted as the only criterion.
Beyond flatline
But is it? The new research challenged this conventional wisdom after Dr. Bogdan Florea from Romania observed a human patient in an extreme deep hypoxic (deprived of oxygen) coma under powerful anti-epileptic medication (required to control his seizures) and observed some unusual EEG (brain-wave) signals instead of just a flatline, and then contacted the University of Montreal team.
After looking at the EEG and other data, the team “realized that there was cerebral activity, unknown until now, in the patient’s brain,” said Dr. Florin Amzica, director of the study and professor at the University of Montreal’s School of Dentistry.
Amzica’s team then decided to recreate the patient’s state in cats, the standard animal model for neurological studies. Using a higher amount isoflurane anesthetic than normal, they placed the cats in an extremely deep coma (beyond what is. The cat EEG showed the expected flat (isoelectric) EEG line./.../

Abstract

Purpose. We describe in detail a relatively simple technique of fundus photography in human and rabbit eyes using a smartphone, an inexpensive app for the smartphone, and instruments that are readily available in an ophthalmic practice. Methods. Fundus images were captured with a smartphone and a 20D lens with or without a Koeppe lens. By using the coaxial light source of the phone, this system works as an indirect ophthalmoscope that creates a digital image of the fundus. The application whose software allows for independent control of focus, exposure, and light intensity during video filming was used. With this app, we recorded high-definition videos of the fundus and subsequently extracted high-quality, still images from the video clip. Results. The described technique of smartphone fundus photography was able to capture excellent high-quality fundus images in both children under anesthesia and in awake adults. Excellent images were acquired with the 20D lens alone in the clinic, and the addition of the Koeppe lens in the operating room resulted in the best quality images. Successful photodocumentation of rabbit fundus was achieved in control and experimental eyes. Conclusion. The currently described system was able to take consistently high-quality fundus photographs in patients and in animals using readily available instruments that are portable with simple power sources. It is relatively simple to master, is relatively inexpensive, and can take advantage of the expanding mobile-telephone networks for telemedicine.

QUANDO OS MOOCS NÃO SÃO MOOCS

O MS adverte : os conceitos emitidos aqui podem causar uma revolução na forma como você pensa que a educação deve ser produzida– ensino e aprendizado – especialmente nas universidades.
Reginaldo Albuquerque


QUANDO OS MOOCS NÃO SÃO MOOCS

Continuamos hoje com um novo artigo sobre os MOOCS. O primeiro desta série foi publicado nos sites: www.canvas-moocs.blogspot.com.br,www.unasus.gov.br, e www.observasaude.org.br e na primeira semana alcançou 300 visitas. Uma boa repercussão, novas dúvidas e algumas críticas. Uma delas me deixou particularmente feliz ao referir o artigo como uma colcha de retalhos. Nada mais significativo. MOOCS é também um espaço, às  vezes uma loja, onde as pessoas trocam ou vendem os seus pertences indesejados. O nome é perfeito para esta concepção de curso, um espaço de troca de conhecimentos, de conteúdos, de vivências, etc. Não se trata de um conteúdo estático que não se renova e não se integra com o grupo que dele participa. É uma inovação disruptiva como são aquelas que ajudam a criar novos valores causando uma desorganização nos valores presentes.

A desconstrução leva  ao ambiente do futuro. Usualmente,  ao propor mudanças nos  paradigmas existentes,  causam revoluções tecnológicas e cognitivas. Como exemplo, temos a introdução do computador pessoal que evoluiu de uma brincadeira para crianças e em 20 anos eliminou os grandes computadores.  Incomoda, assim, a muita gente que precisa desaprender os seus paradigmas de trabalho. E isto é difícil. Muito difícil. 

MOOC é um conceito desenvolvido no movimento OPEN EDUCATIONAL RESOURCES. Usa tecnologias da web 3.0 e assim permite a adição de páginas ativas no material textual.  Um vídeo pode ser parado para introdução de explicações e perguntas, uso exaustivo de hipertextos, avaliações dinâmicas com registro dos percursos dentro do website, revisão por pares, uso de hangouts, skypes, rede sociais, etc.
