Transplante fecal?

Citando:
"Performing the transplant

The problem with C. difficile is that patients will have multiple bouts of watery and even bloody diarrhoea every day, tummy cramps, fever and in the most severe cases the infection is fatal.

The best that medicine has to offer is more antibiotics; it is the definition of a vicious circle.

A stool transplant - or to give it its full title "a faecal microbiota transplant" - aims to repopulate the patient's gut with the microbes from a healthy person.

A relative is often used as they would have had similar gut bacteria.

After a "sample" is produced, it is mixed with water.

Some techniques break the poo up by hand while others blitz it in a household blender.

There are two routes for getting the sample into the required location - down through the mouth or up through the rectum."
(...)
"But will trans-poo-sions mean anything for medicine beyond C. difficile?

The interaction between our human and microbial selves is being investigated in nearly every disease you can think of.

The microbiome has been linked to diseases including inflammatory bowel disease, diabetes, Parkinson's, whether cancer drugs work and even depression and autism.

But this means there could be unintended consequences of a faecal transplant.

There was a report in 2015 of a woman gaining 36lb (16kg) and being classed as obese after a transplant from her daughter.

It is possible to make mice thinner or fatter by transplanting into them the microbiome from either a lean or obese human, although the jury is still out on whether the same rules apply in people."

Cura de diabetes tipo 1?

... em ratos. Para já:
https://veja.abril.com.br/saude/pesquisa-aponta-para-possivel-cura-da-diabetes-tipo-1/

Citando:
"A cura para a diabetes tipo 1 pode estar próxima. De acordo com um estudo publicado na-segunda feira, na revista NatureCommunications, pesquisadores espanhóis estão desenvolvendo uma droga capaz de regenerar as células produtoras da insulina. No entanto, os testes foram feitos apenas em animais e os cientistas alertam que a disponibilidade do tratamento no mercado ainda pode estar a alguns anos de distância."

O estudo sobre os estudos que recomenda que as 100g de alcool não sejam ultrapassados por se

... Mas o que são 100g de alcool? São mais ou menos 2*5 copos de bebidas / dia, sendo que os copos estão normalmente dimensionados para conter cerca de 10g,. Ou seja, 10 copos por semana?
É só fazer as contas, "como dizia o outro".  Mas cuidado com os copos, porque há copos de cerveja que são canecas.
Citando a Wikipedia:

"Uma unidade de bebida padrão é uma forma simplificada de medir o volume de álcool puro numa bebida alcoólica, sendo usada em vários países para orientar e facilitar o cálculo da ingestão diária ou semanal de álcool. Embora as bebidas tenham diferentes graduações alcoólicas, os diferentes tipos e tamanhos de copos fazem com que a quantidade de álcool ingerida seja praticamente a mesma, o que corresponde a 10 – 12 gramas de álcool por copo ou uma unidade de bebida padrão. A Organização Mundial de Saúde recomenda que não sejam ultrapassadas as 2 unidades diárias (20 g álcool) e a abstinência durante dois dias por semana.^[1]

	Cerveja	Vinho	Aperitivo	Aguardente
Capacidade do copo	3 dl	1,65 dl	0,5 dl	0,5 dl
Conteúdo de álcool puro	12 g	12 a 13 g	10 a 12 g	14 a 16 g

As influências dos interessados nos estudos?

Alguns dados sobre a relação da indústria (alimentar, bebidas alcoólicas, não alcoólicas, farmacêutica etc.) e os  investigadores:

Citando:
"Health claims about alcohol are back in the news, but this time, the headlines are about the scientists who make those claims — not the actual data.

Recently published investigations by The New York Times, Wired and Stat paint a disturbing picture about the way alcohol companies are trying to influence scientific understanding, and thus public perception, of alcohol as a health tonic. 

These stories reveal that officials at the National Institutes of Health’s National Institute on Alcohol Abuse and Alcoholism (NIAAA) aggressively courted alcohol executives to fund a $100 million clinical trial on “moderate drinking” with the expectation that this study would probably conclude that it is safe and lowers the risk of disease. 

Alcohol executives were allowed to help pick the scientists and preview the trial’s design, reports the Times, while Wired reported on how dependent the NIAAA is on industry funding to complete the expensive, long-term study. Finally, Stat has a story about how scientists who published unflattering research about the alcohol industry were verbally abused by NIAAA officials and cut off from funding.

Even though prestigious alcohol scientists may insist on their independence, studies show that research funded by the food industry is four to eight times more likely to conclude something that financially benefits the sponsor. Industry-funded research also tends to suppress negative data. When pharmaceutical companies fund studies, the findings are less likely to be published than research funded by other sources."
