"(...) the new technique designed to reduce the risk of mothers passing on mitochondrial disease to their children, which is debilitating and often life-limiting.
Mitochondrial disease is a chronic, genetic disorder that occurs when the mitochondria of the cell fail to produce enough energy for cell or organ function, according to MitoAction, a US-based organisation working to improve quality of life for adults and children affected by the disease."

Microsoft usa dados de pesquisa para antecipar diagnóstico de Cancro Pancreático
https://www.washingtonpost.com/news/innovations/wp/2016/06/10/what-happens-when-your-search-engine-is-first-to-know-you-have-cancer/
Citando:
"The Microsoft researchers identified Web users who had recently searched for queries indicating they have pancreatic cancer, such as “I was told I have pancreatic cancer, what to expect,” and then looked back months earlier to examine patterns in the symptoms that the users searched for. This included phrases such as “dark or tarry stool,” “abdominal swelling,” “dark urine” and “yellowing skin.”
From this analysis they realized trends in the queries of users who were soon to be diagnosed with pancreatic cancer, identifying 5 to 15 percent of cases with low false-positive rates. The research was published in the Journal of Oncology Practice."

"Findings of the study show 90.5% of the stroke burden was attributable to "modifiable factors" such as smoking, eating too much sugar and not exercising enough, as well as the associated health problems, such as diabetes and heart disease.
Doctors say changing lifestyle and habits in developing countries is a major concern for increasing burden of non-communicable diseases.
The study also listed air pollution as a "modifiable factor", indicating efforts by the government and people can make a difference."

"Globally, about 15 million people suffer strokes every year, of which nearly 6 million die and 5 million are left disabled including loss of vision or speech, paralysis and confusion."

Contaminação por Listeria e recolha de snacks (Meningite)
Eis o que uma contaminação de sementes de girassol por Listeria pode provocar (a bactéria pode provocar septicemia ou meningite e é especialmente perigosa para idosos, crianças e grávidas): uma recolha em massa de lotes de produtos.

"Food Safety New Zealand says listeriosis is a rare but potentially life-threatening disease with a high death rate.
Listeria symptoms can be flu-like, including high temperature, aches, chills, vomiting and diarrhoea.
"Healthy adults are likely to experience only mild infection, causing flu-like symptoms or gastroenteritis.
"However, Listeria infection can occasionally lead to severe blood poisoning (septicaemia) or meningitis."

Leucemia do tipo AML tem afinal 11 subtipos

"Researchers said that acute myeloid leukaemia (AML) is not a single disorder, but at least 11 different diseases comprising different constellations of genetic changes."
(...)
"They analysed more than 100 genes known to cause leukaemia, to identify common genetic themes behind the development of the disease.
They found that the patients were divided into at least 11 major groups, each with different constellations of genetic changes and distinctive clinical features."

Mutação de gene associada a certo tipo de Esclerose Múltipla
http://www.bbc.com/news/health-36416531
Citando:
"The mutation is in a gene called NR1H3, which makes a protein that acts as a switch controlling inflammation.
In MS the body's immune system mistakenly attacks the protective layer of myelin that surrounds nerve fibres in the brain and spinal cord, leading to muscle weakness and other symptoms."
(...)
"The researchers believe stopping the inflammation early might prevent or delay the disease. They already have drugs in mind that might do this by targeting the NR1H3 gene pathway.
These drugs are in development for other diseases, including cardiovascular disease and diabetes."
(...)
"[This MS] variant itself is rare and most people with MS won't have it. "

"The condition causes the immune system to attack the lining of nerves in the brain and spinal cord. Most patients are diagnosed in their 20s and 30s.
One existing treatment is for the immune system to be suppressed with chemotherapy and then stem cells are introduced to the patient's bloodstream - this procedure is known as an autologous haematopoietic stem cell transplant (HSCT).
(...)
But in this study, Canadian researchers went further - not just suppressing the immune system, but destroying it altogether.
It is then rebuilt with stem cells harvested from the patient's own blood which are at such an early stage, they have not developed the flaws that trigger MS.
The authors said that among the survivors, over a period of up to 13 years, there were no relapses and no new detectable disease activity."
(...) "1 person died".
