Smokers in clinical studies who say they’ve quit often haven’t

Smokers in clinical studies who say they’ve quit often haven’t

SOCIETY FOR THE STUDY OF ADDICTION

A new US study published by the scientific journal Addiction has found that a high proportion of smokers enrolled in stop-smoking programs during a hospital stay report having quit when in fact they have not. The findings mean that in these kinds of study it is vital to check claims of having quit using an objective measure.

This nationwide study followed five large smoking cessation clinical trials in the US that enrolled smokers at hospitalization. At 6-month follow-up, 822 participants (out of 4,206 who completed the follow-up survey) reported they had not smoked in the past 7 days and provided a usable saliva sample for verification by testing for a chemical called ‘cotinine’. The liver converts nicotine in the body to cotinine and so this chemical is a very accurate measure of whether someone has smoked in the past few days. More than 40% of those 822 self-reported quitters failed the saliva test.

The misreporting rate may be even higher because, despite the offer of $50 to $100 for providing a sample 18.6% of people who had said they had quit smoking did not reply, even after multiple attempts. These participants were excluded from the study. The study also excluded anyone who said they were using another nicotine product such as smokeless tobacco, nicotine patches or e-cigarettes. Even very heavy exposure to other people smoking would not have raised cotinine levels to those found in this study.

Lead author Dr. Taneisha Scheuerman says “Our study shows that in studies where participants may feel pressure to say they have quit when they have not, it is essential to verify claims of quitting using an objective test such as cotinine to know true quit rates. For clinical researchers, another important finding is that misreporting rates were similar across intervention and control conditions, suggesting that the relative effectiveness of interventions tested was the same using self-report and cotinine levels.”

Professor Robert West, Editor-in-Chief of the journal, Addiction, that published the article comments, “Other research has shown very low misreporting rates in population surveys of smoking. Hospital patients and pregnant women would be likely to feel strong pressure to have stopped smoking.”

One cannot help but wonder what the outcome would be for alcohol

Most adolescents suffer from Gender confusion

Most adolescents suffer from Gender confusion

Seven chimpanzees of different ages and sexes living in the Primate Research Institute at Kyoto University were part of the experiment. They sat in a booth housing a computer-based touchscreen and were trained to choose the stronger of two options (based on the rules of the game) they saw on screen. They first learnt the paper-rock sequence, then the rock-scissors one and finally the scissors-paper combination. Once they knew how the pairs fitted together, all the different pairs were randomly presented to them on screen. Five of the seven chimpanzees completed the training after an average of 307 sessions.

The findings show that chimpanzees can learn the circular pattern at the heart of the game. However, it took them significantly longer to learn the third scissors-paper pair than it did to grasp the others, which indicates that they had difficulty finalizing the circular nature of the pattern.

The research team then also taught the game to 38 preschool children to compare the learning process of chimpanzees with that of humans aged three to six. The children had little difficulty grasping the game, and on average did so within five sessions. Their performance was, however, subject to age. The older the children were, the more accurate they became when all three pairs were randomly presented to them. Participants older than 50 months (about four years) played the game with more skill rather than luck.

“This suggests that children acquire the ability to learn a circular relationship and to solve a transverse patterning problem around the age of four years,” says Gao. “The chimpanzees’ performance during the mixed-pair sessions was similar to that of four-year-old children,” adds Gao, who hopes the findings will inspire future studies into how age and sex influence the ability of members of various species to learn circular relationships.

There are  but two genders

much has been written about the gender confusion during early adolescence but biology and evolution proves all mammals have only 2 : male and female 

The mammal Homo Sapiens has adopted the psychological construct there could be a rainbow of genders. Which science did prove long time ago has shown that the physical build of the brain determines gender

In other words there is a thing as gender dysphoria

A tiny minority but unfortunately loud political correctness platform made it look like a majority.

please stop

pretty please?

So does PM2.5 actually kill that many people?

So does PM2.5 actually kill that many people?

Or really anyone at all? A new study just published in the journal Regulatory Toxicology and Pharmacologydrives a stake through the heart of EPA’s claims.

The study compared daily PM2.5 levels in California with daily death counts during the 13 years between 2000 to 2012. Over those 4,745 days, no association could be found between PM2.5 levels and the over two million deaths included in the analysis. EPA claims that elderly people are most vulnerable to the allegedly lethal effect of PM2.5. But the California study specifically examined this issue and found no association between PM2.5 and deaths among the elderly.

Without a doubt this is the largest and best-conducted epidemiologic study ever on PM2.5. Virtually every death in California was considered and the state is meticulous about its air-quality data. California has the ultimate range in air quality, from the best to the worst in the U.S. In comparison, previous EPA-funded studies have focused only on limited (read “cherry-picked”) urban areas, rely on guesstimated or assumed PM2.5 levels and often include deaths from accidents, homicides and other causes that can’t possibly be related to PM2.5.

Wind Powered Energy

Wind Powered Energy

As machines, wind turbines are pretty good already; the problem is the wind resource itself, and we cannot change that. It’s a fluctuating stream of low–density energy. Mankind stopped using it for mission-critical transport and mechanical power long ago, for sound reasons. It’s just not very good.

As for resource consumption and environmental impacts, the direct effects of wind turbines — killing birds and bats, sinking concrete foundations deep into wild lands — is bad enough. But out of sight and out of mind is the dirty pollution generated in Inner Mongolia by the mining of rare-earth metals for the magnets in the turbines. This generates toxic and radioactive waste on an epic scale, which is why the phrase ‘clean energy’ is such a sick joke and ministers should be ashamed every time it passes their lips.

It gets worse. Wind turbines, apart from the fibreglass blades, are made mostly of steel, with concrete bases. They need about 200 times as much material per unit of capacity as a modern combined cycle gas turbine. Steel is made with coal, not just to provide the heat for smelting ore, but to supply the carbon in the alloy. Cement is also often made using coal. The machinery of ‘clean’ renewables is the output of the fossil fuel economy, and largely the coal economy.

A two-megawatt wind turbine weighs about 250 tonnes, including the tower, nacelle, rotor and blades. Globally, it takes about half a tonne of coal to make a tonne of steel. Add another 25 tonnes of coal for making the cement and you’re talking 150 tonnes of coal per turbine. Now if we are to build 350,000 wind turbines a year (or a smaller number of bigger ones), just to keep up with increasing energy demand, that will require 50 million tonnes of coal a year. That’s about half the EU’s hard coal–mining output.

Common sense enters salt intake debate

Common sense enters salt intake debate

“We saw no evidence that a diet lower in sodium had any long-term beneficial effects on blood pressure,” said Moore. “Our findings add to growing evidence that current recommendations for sodium intake may be misguided.”

The 2015-2020 Dietary Guidelines for Americans recommends limiting sodium intake to 2,300 grams a day for healthy people. For the study, the researchers followed 2,632 men and women ages 30 to 64 years old who were part of the Framingham Offspring Study. The participants had normal blood pressure at the study’s start. However, over the next 16 years, the researchers found that the study participants who consumed less than 2500 milligrams of sodium a day had higher blood pressure than participants who consumed higher amounts of sodium.

Other large studies published in the past few years have found what researchers call a J-shaped relationship between sodium and cardiovascular risk–that means people with low-sodium diets (as recommended by the Dietary Guidelines for Americans) and people with a very high sodium intake (above the usual intake of the average American) had higher risks of heart disease. Those with the lowest risk had sodium intakes in the middle, which is the range consumed by most Americans.

“Our new results support these other studies that have questioned the wisdom of low dietary sodium intakes in the general population,” said Moore.

The researchers also found that people in the study who had higher intakes of potassium, calcium and magnesium exhibited lower blood pressure over the long term. In Framingham, people with higher combined intakes of sodium (3717 milligrams per day on average) and potassium (3211 milligrams per day on average on average) had the lowest blood pressure.

Does Glyphosate Cause Cancer?

Does Glyphosate Cause Cancer?

Conclusion

I am simply searching through PubMed to find reviews of the safety of glyphosate, and this is what I find. You can do the same, it’s a user-friendly searchable database. There is a remarkable consistency to the reviews – they all agree that the evidence does not support an association between glyphosate exposure and any adverse health outcome. The IARC are the only outliers, and yet their flawed and quirky conclusion is the one that garnered the most attention.

There is also a theme in the reviews that we could use more and better quality studies. To put that into context, however, that is almost always the conclusion of such reviews. It is difficult to prove a negative – a lack of a correlation. Such a negative conclusion is only as good as the data supporting it, and therefore the more and more rigorous the data the better the conclusion.

We can always use more and better data when it comes to safety, but the existing data is robust, consistent, and independently replicated, and includes both glyphosate and formulations with glyphosate.

Glyphosate, in fact, is one of the safer pesticides in use (including many organic pesticides). It has replaced far more toxic herbicides. Opposing glyphosate because of unwarranted fears of toxicity is likely to cause harm due to whatever replaces it. Tilling is bad for the soil and releases CO2 into the atmosphere, and we cannot feed the world through hand weeding. Herbicides have to be part of the equation, and glyphosate is one of the safest out there.
