Epidemiology pushes out a lot of dumb papers. Not as many as social psychology per capita but in volume a whole lot more. It's easy to see why the public believes horse de-wormer cures COVID-19, it was in an epidemiology paper, and that methodology was just as valid as a paper this week 'linking' olive oil to longer life. 

Do be careful, masks, distancing, get vaccinated, ventilation, avoid crowded places, test, trace, isolate, quarantine. #DOITALL - BE CAREFUL

I am posting this after Boris Johnson announced - to much celebration - that the UK will end its mask mandate again because cases of Omicron are falling.

This is not about the economy. Wearing masks has zero economic impact - who is going to be impacted economically by you wearing a mask in public transport or in a shop? It seems to be more about a concept of freedom that some have, that we are more free if we don't use masks to protect others from a sometimes deadly disease. How is that freedom?

All coronaviruses, and certainly SARS-CoV-2, have become famous as a respiratory virus, but acute COVID-19 infection has been linked to many different organ systems, including the brain, resulting in a wide range of neurological complications with long-lasting impacts.

 According to a new paper by Serena Spudich and Avindra Nath, cases of neurological “Long Covid” symptoms may result from the emergence and persistence of these mechanisms and the neurological symptoms that accompany COVID-19.

A new study finds that oral stimuli during the chewing of food can help increase energy expenditure of body and prevent obesity.

Chew your food well is ancient wisdom.  In the past, the belief was perhaps because there was less food anyway. Chewing it longer gave the brain and stomach time to catch up with each other. Many people have reported 'their eyes are bigger than their stomach' and feeling hungry until they were very full. Others said it made digestion easier.

In 2008, Senator Barack Obama was opposed to gay marriage and worried vaccines might cause autism. A few years later he said neither of those things.

Did Democrats flip to being pro-science and the party followed and then the President reflected those polls? Perhaps he changed from stating party platforms based on voter beliefs to his own once he was elected, then he changed the party, and then the party led its members, finds results in a new paper on party and personal political polarization. 

Magnesium is important in the immune system’s ability to tackle pathogens and even cancer cells but that doesn't mean you should run to a supplement huckster or naturopath. It is magnesium in blood that is needed for T cells to operate efficiently and that means science and medicine, not woo.

Some studies, though only in mice so strictly observational, found that cancerous growths spread faster when the animals received a low-magnesium diet – and also that their defense against flu viruses was also impaired. Lacking a plausible biological mechanism for exactly how this mineral affects the immune system leaves such studies in the interesting but not clinically relevant camp.

Prior to 2021, if you found an anti-vaxxer, it was also going to be someone who bought organic food and thought cell phones cause cancer. While some kooky Republicans have taken over for some of the wacky left-wing people that deny vaccines, organic food and 5G conspiracy theories are thankfully still only one party and thus don't get much media attention from their political tribe in corporate journalism.

Even before the COVID-19 pandemic, 81 countries, rich and poor, mostly do poorly on how well their health systems provide for the physical and mental wellbeing of patients at the end of life.

When it comes to baseball and football, coaches always know the numbers. That helps them make informed decisions on risk and reward. Less well-known is that clinicians also often make important healthcare decisions with the aid of algorithmic tools that draw on large amounts of complex data.

If you believe solar power is ready for mass usage, you are likely an activist, in the industry, or one of the customers who really believes they are selling electricity back to the utility at the same price they are paying when they need it and it isn't being paid for by people in the apartments that we get told are better for the environment than single-family homes.

Without mandates and subsidies, plus fees tacked onto every non-solar-using customer, the industry would go back to the niche it was prior to 2010. Since 2010, the share of conventional energy needed has not moved while the world spent trillions underwriting alternatives.(1)
