Relação entre proximidade a estradas movimentadas e demência?

Citando:
"As many as 11% of dementia cases in people living within 50m of a major road could be down to traffic, the study suggests.
The researchers, who followed nearly 2m people in Canada over 11 years, say air pollution or noisy traffic could be contributing to the brain's decline.
UK dementia experts said the findings needed probing but were "plausible"."


2 milhões de pessoas foram seguidas por cerca de 11 anos:
"There were 243,611 cases of dementia diagnosed during that time, but the risk was greatest in those living closest to major roads.
Compared with those living 300m away from a major road the risk was:
◾7% higher within 50m
◾4% higher between 50-100m
◾2% higher between 101-200m
The analysis suggests 7-11% of dementia cases within 50m of a major road could be caused by traffic.
The researchers adjusted the data to account for other risk factors like poverty, obesity, education levels and smoking so these are unlikely to explain the link."

Ora aqui está a maneira correcta de definir um guia de saúde (health guide)

Alguns países como os US e o RU têm linhas orientadoras para a saúde (com resultados desastrosos). Talvez a forma como o casa
Canadá as está a rever seja a melhor forma de as definir:
Por consulta pública:

"Health Canada is currently in the process of reviewing and seeking input to update the food guide. The public consultations end Dec. 8."

Uso off-label de anti-depressivos justifica aumento explosivo do uso?

Estudo usou campo de BD que indica o motivo da prescrição.
A lista dos 8 principais usos off-label está no estudo (inclui insónias, ansiedade, enxaqueca e outras "parvoíces").

Outro dado "precioso" é que o uso pediátrico é off-label. Citando:
"Many off-label uses are backed by scientific evidence from clinical trials, just not full government approval, as the list above demonstrates. Off-label drug use is also common in certain populations, especially among children, because most drugs prescribed to pediatric patients were never tested in children. This makes many pediatric prescriptions necessarily off-label."
