Citando:
"The testing techniques used in the new research meant only a subset of pesticides could be detected. Two very common pesticides – glyphosate and chlorothalonil – were not included in the study, meaning the findings represent a minimum level of contamination. The research focused on streams, as these harbour a large proportion of aquatic wildlife."

Álcool não protector

Citando:
"A glass of wine or beer a day may not protect you from serious heart and circulatory disease, as a new study shows every alcoholic drink raises the chances of a stroke.

Moderate drinkers, who had one or two drinks a day, saw their stroke risk rise around 15 per cent compared to non-drinkers and this increased the more they drank, the University of Oxford led research found."

Alzheimer e luz e som?

Citando:
"Em experiências realizadas em ratos de laboratório, aglomerados de proteínas prejudiciais que interferem nas funções cerebrais foram parcialmente eliminados usando apenas luz e som, melhorando a função cognitiva dos animais.

Esta técnica ainda não foi clinicamente testada em humanos. Por este motivo, ainda é muito cedo para dizer que seria uma técnica viável. Além disso, adianta o HypeScience, os ratos foram geneticamente modificados para apresentarem sintomas parecidos com a condição em humanos.

No entanto, os resultados iniciais indicam uma forma barata e simples de tratar esta forma tão comum de demência.

Tudo começou em 2015, quando a neurocientista Li-Huei Tsai, diretora do Instituto Picower de Aprendizagem e Memória do MIT, trabalhou numa experiência que tinha como objetivo manipular a atividade do cérebro piscando uma luz branca no rosto destes animais."

Arranhão de gato e...

... esquizofrenia?

Citando:
"O verdadeiro culpado pelo declínio da saúde mental do adolescente foi uma bactéria associada ao que é conhecido como “doença do arranhão do gato”. O paciente está bem, mas o caso deixou os investigadores curiosos sobre as ligações entre infeção e doença neurológica.

A Bartonella henselae é uma bactéria que costuma estar presente no sangue de gatos, especialmente crias. Transmitido através de uma mordida ou arranhão, pode produzir inchaço e lesões localizadas e, ocasionalmente, problemas mais sérios no coração e no sistema nervoso. Mas uma coisa pela qual não é conhecida é por causar esquizofrenia."

Sobre a resistência aos antibióticos

https://www.theguardian.com/global/2019/mar/24/the-drugs-dont-work-what-happens-after-antibiotics

Citando:
"Antimicrobial resistance (AMR) – the process of bacteria (and yeasts and viruses) evolving defence mechanisms against the drugs we use to treat them – is progressing so quickly that the UN has called it a “global health emergency”. At least 2 million Americans contract drug-resistant infections every year. So-called “superbugs” spread rapidly, in part because some bacteria are able to borrow resistance genes from neighbouring species via a process called horizontal gene transfer. In 2013, researchers in China discovered E coli containing mcr-1, a gene resistant to colistin, a last-line antibiotic that, until recently, was considered too toxic for human use. Colistin-resistant infections have now been detected in at least 30 countries."
(...)
"Making a dent in antibiotic resistance will require such international efforts. Some 90% of forecast deaths from AMR will take place in Africa and Asia – the countries where antibiotic overuse, and resistant infections, are highest. When the AMR review was published in 2016, O’Neill was encouraged by the international response. But since then, Brexit and the Trump administration have knocked AMR off the news agenda. And despite enthusiastic rhetoric, pharmaceutical companies continue to tread water.

“I occasionally think that pharmaceutical company CEOs say to themselves, ‘We’ll just wait until it becomes a real crisis,’” says O’Neill."

Bebidas quentes e cancro?

https://www.cmjornal.pt/sociedade/detalhe/beber-cha-quente-aumenta-o-risco-de-cancro-do-esofago

Citando:
"De acordo com a investigação, publicada esta quarta-feira no International Journal of Cancer, quem bebe mais de 700ml de chá a uma temperatura superior a 60ºC, corre 90% mais riscos de ter cancro do esófago do que as pessoas que bebem menos chá, a temperaturas inferiores.  

O estudo, com Farhad Islami, da Sociedade Americana de Cancro, como principal autor, avaliou mais de 50 mil pessoas em Golestan, no Irão. Muitas pessoas gostam de beber bebidas quentes, como café e chá, mas o investigador relembra a importância de "esperar que as bebidas quentes arrefeçam" antes de serem consumidas."

Escovar os dentes bem?

https://www.theguardian.com/lifeandstyle/2019/mar/17/how-to-clean-your-teeth-properly

Citando:
"There is some evidence that small-headed electric toothbrushes tend to be a bit better than manual brushes – but make sure you still use them in a systematic way.

Brushing your teeth fights gum disease; fluoride toothpaste stops the decay. Spit the toothpaste out but don’t rinse out. Mouthwash by itself is not going to do the job that brushing with toothpaste does. If you do want to use mouthwash, again spit rather than rinse.

Ask your dentist or hygienist about flossing. For most people, good brushing will be enough. Others may be more susceptible to gum disease and have to do more, such as using interdental brushes (for gaps between teeth) and floss (where your teeth have tight contact)."

Infertilidade masculina, nova descoberta

"It is said that in life the journey is more important than the destination.

And for sperm, that is certainly the case, according to a new scientific study.

Researchers have discovered that the sperm of infertile men is every bit as healthy as fertile men while it is still in the testicles."

Cogumelos previnem demência?

Boa correlação para certos tipos de demência:
https://www.bbc.com/news/health-47554966

Citando:
"'Encouraging'

Mild cognitive impairment (MCI) can make people forgetful, affect their memory and cause problems with language, attention and locating objects in spaces - but the changes can be subtle.

It is not serious enough to be defined as dementia.

The participants in the study were asked how often they ate six different types of mushrooms: oyster, shiitake, white button, dried, golden and tinned.

Mushroom eaters performed better in brain tests and were found to have faster processing speed - and this was particularly noticeable in those who ate more than two portions a week, or more than 300g (10.5oz).

"This correlation is surprising and encouraging," said assistant professor Lei Feng, the lead study author, from the university's department of psychological medicine."
