"Fabrizio "Fab" Stabile, 29, of the Atlantic City-area beach community of Ventnor City died Sept. 21, just one day after he was diagnosed with the brain-eating amoeba, Naegleria fowleri, according to a GoFundMe page that aims to create the Fabrizio Stabile Foundation. Stabile had been at a wave pool at BSR Cable Park's Surf Resort in Waco, Texas, and subsequently suffered from a headache Sept. 16 that progressed to an inability to get out of bed or speak coherently.

He was hospitalized Sept. 17, but doctors at first thought he had bacterial meningitis, which delayed the proper treatment. Only four people have survived the

► June 2017: Who's to blame for lake's brain-eating amoeba?
► June 2017: Deadly brain-eating amoeba symptoms are difficult to identify

Naegleria fowleri, known as the “brain-eating amoeba,” usually infects people when contaminated water, generally from lakes, rivers or streams, enters the body through the nose, according to the federal Centers for Disease Control and Prevention. 

Once the parasite enters the nose, it travels to the brain where it can cause a fatal infection known as primary amebic meningoencephalitis. Symptoms start to show one to nine days after swimming, and infected people typically die one to 18 days after symptoms start, according to the CDC."

Novo composto protege contra UVA (mitoiron claw)

http://www.techtimes.com/articles/170872/20160722/new-sunscreen-compound-offers-cellular-level-protection-against-uva-rays.htm

Citando:
"Numerous sunscreens are available in the market today but most of them protect well only against UVB rays, leaving UVA protection limited. This is problematic because UVA rays penetrate deep into the skin, causing damage at the cellular level.

To address this issue, researchers have uncovered a compound that can be added to sunscreens that offers unexpectedly strong protection against UVA exposure, particularly within the cell where most of the damage related to UVA occurs.

Concentrations of free iron are highest within the mitochondria, the powerhouse of the cell. However, free iron turns into a catalyst for toxic reactive oxygen species when exposed to UVA, facilitating damage to cellular components that lead to increased risks of cancer and cell death.

The custom-designed iron chelator called mitoiron claw that the researchers developed attaches to iron atoms like a claw (hence its name), safely binding excess free iron and keeping them from reacting once exposed to UVA rays.

The researchers carried out tests involving human skin cells exposed to UVA at a rate equivalent to 140 minutes of uninterrupted sun exposure and saw that mitoiron claw-treated cells received complete protection against cell death."

FDA questiona segurança de medicamento da Sanofi (Diabetes)

http://www.fiercebiotech.com/fda-frets-over-safety-sanofi-s-diabetes-combo
Citando:
"The FDA has set up a debate among outside experts over Sanofi’s ($SNY) combo diabetes drug LixiLan today by raising a series of red flags over potential safety issues that could arise if the combination is allowed to reach the market.
In particular, regulatory insiders say that Sanofi’s proposed dose range for the combo, a mix of Lantus and lixisenatide--now dubbed "iGlarLixi"--would likely create some confusion over dosing among physicians, as well as expose some patient groups to adverse risks. The regulator's docs also noted the clear possibility that the final trial data were biased by inadequate dosing of insulin.

Relação entre Fome e Obesidade

Um artigo interessante saiu na NG tenta explicar o facto de nos EUA as pessoas mais pobres (e com maior probabilidade de passar mais fome) serem os mais obesos o que é aparentemente um contra senso.

"The New Face of Hunger", August 2014, National Geographic (US Edition).

Uma linha de explicação explorada é a de que as pessoas sujeitas a ajuda alimentar nos EUA a recebem na forma de comida processada (menos saudável) com muito teor de sal, açúcar e gorduras.
Por outro lado, a comida mais barata é frequentemente processada (fast-food), o que não quer dizer que não se consiga comer barato e de forma saudável. Para isso é preciso literacia.

Outro factor explorado é o facto de 43000 casas em Houston não terem carro e estarem mais de meia milha de um supermercado. Isso aliado à escassez de mercearias e abundância de restaurantes de fast food a cada esquina faz com que as pessoas comam o que não devam e vivam num "food desert".

O artigo começa com uma pergunta de página inteira: Porque estão as pessoas mal nutridas no país mais rico do mundo?

Google for it.
