Deans' stroke musings: Coffee drinking and risk of lung cancer

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Coffee drinking and risk of lung cancer - A meta-analysis

For all the coffee I drink this is good news, not that I ever heard of this as a problem before.
http://www.mdlinx.com/internal-medicine/medical-news-article/2016/04/06/lung-cancer/6606168/?newsdt=040616&subspec_id=0&utm_source=DailyNL&utm_medium=newsletter&utm_content=general-article&utm_campaign=article-section&category=daily-digest&page_id=1

A meta–analysis was conducted to assess the effect of coffee consumption on lung cancer risk independent of tobacco use. The pooled estimates indicated that when the potential confounding effect from smoking is controlled for, coffee drinking does not appear to be a lung cancer risk factor. Further pooled analyses, with larger non–smokers population size, are encouraged to confirm these results. Impact: This study illustrates that the association between coffee consumption and lung cancer can be confounded by tobacco smoking.

Methods

A systematic review and a meta–analysis based on random effects models were performed using studies from the PubMed and EMBASE databases, and the references from the retrieved articles.
Included were 8 prospective cohorts and 13 case–control studies, which provided data for 19,892 cases and 623,645 non–cases, timeframe 1986–2015.

Results

The meta–relative risk for coffee drinking, not controlling for tobacco smoking, was 1.09 (95%CI 1.00–1.19), reference group was never drinkers.
There was significant heterogeneity among the study results (Q= 84.39, I² = 75.1%, heterog. p– value < .001).
Among non–smokers, coffee was not associated with lung cancer risk (RR= 0.92, 95%CI 0.75–1.10), reference group was never drinkers.
The meta–RR for 1 cup/day increase, unadjusted for smoking, was 1.04 (95%CI 1.03–1.05); the corresponding RR for non–smokers was 0.95 (95%CI 0.83–1.09).
