  1. HEI study in Europe finds evidence of health effects at lower levels of air pollution https://www.greencarcongress.com/2021/09/20210925-hei.html "The shape of the associations with natural cause mortality showed steeper slopes at lower exposures, with no evidence of concentrations below which no associations were found for PM2.5, BC, and NO2."
  2. I don't understand so far the extremely lackadaisical attitude organizations of all types seem to be taking towards the concept of air filtration. Why aren't schools, businesses, government buildings, etc retrofitting UV air sterilization and improved filtering into their ventilation? Here's a recent study showing on how much incredible improvement in air safety can be achieved via relatively simple and straightforward means. " Airborne SARS-CoV-2 was detected in the ward on all five days before activation of air/UV filtration, but on none of the five days when the air/UV filter was operational; SARS-CoV-2 was again detected on four out of five days when the filter was off. Airborne SARS-CoV-2 was infrequently detected in the ICU. Filtration significantly reduced the burden of other microbial bioaerosols in both the ward (48 pathogens detected before filtration, two after, p=0.05) and the ICU (45 pathogens detected before filtration, five after p=0.05).

  4. Here's more on brain damage from even mild infection cases. Matched MRI scans of people before/after infection. https://theconversation.com/preliminary-research-finds-that-even-mild-cases-of-covid-19-leave-a-mark-on-the-brain-but-its-not-yet-clear-how-long-it-lasts-166145 https://www.medrxiv.org/content/10.1101/2021.06.11.21258690v3.full-text
  5. BTW, that news a while back that PhDs are the most vaccine resistant was just bogus data: https://coronavirus.quora.com/Is-it-true-that-PhDs-are-the-most-vaccine-resistant-group-https-www-nationalreview-com-corner-the-most-vaccine-hesita-1
  6. Twitter thread and link to paper from July showing long term kidney damage even in non-hospitalized covid cases:
  7. Attempting to only mask up when you feel sick doesn't work well with this variant in particular. Studies have shown the most contagious period is in the 2 days before you show symptoms (if you get symptoms at all), and that vaccinated individuals have roughly comparable viral load/spreading ability during this initial time period compared to non-vaccinated.

  9. The Economist is keeping an updated estimate of worldwide covid deaths, and by country. Currently we're up to 15 million worldwide, around 800k in USA. These are estimates driven in part by a machine learning algo:
  10. Chlorpyrifos slows down the burning of calories in the brown adipose tissue of mice https://www.sciencedaily.com/releases/2021/08/210827184147.htm The EPA is banning chlorpyrifos https://theconversation.com/the-epa-is-banning-chlorpyrifos-a-pesticide-widely-used-on-food-crops-after-14-years-of-pressure-from-environmental-and-labor-groups-166485
  11. https://www.sciencedaily.com/releases/2021/08/210818135218.htm How fructose in the diet contributes to obesity "Eating fructose appears to alter cells in the digestive tract in a way that enables it to take in more nutrients, according to a preclinical study. These changes could help to explain the well-known link between rising fructose consumption around the world and increased rates of obesity and certain cancers."
  12. It would be good to start differentiating between quoting news/data from countries like the UK that primarily vaccinated with a less effective vaccine against the delta variant, vs the US or Israel that mostly used a more effective Pfizer or Moderna vaccine particularly among the more susceptible older folks. It's really an apples vs oranges comparison.

    Starting a CR Diet

    If you like having more brain cells vs. less brain cells, avoid alcohol: Drinking any amount of alcohol causes damage to the brain, study finds https://www.cnn.com/2021/05/19/health/alcohol-brain-health-intl-scli-wellness/index.html
  15. It would be interesting just to try a walk after eating the exact same meal that caused a spike, and see what happens. If it helps, you can consider then getting a slow walking-speed treadmill, I use one at my sit/stand/walk desk after breakfast and lunch while doing work on my computer.
  16. Gordo the deaths always lag cases by 3 to 4 weeks. Takes a while for people to progress through the stages of infection/test -> hospitalization -> death. Same pattern repeats every time there is a new upsurge in cases throughout the pandemic.

    Whole Body Vibration Therapy for Bone Health

    Low magnitude vibration alleviates age-related bone loss by inhibiting cell senescence of osteogenic cells in naturally senescent rats https://www.aging-us.com/article/202907/text
  18. Strain on NHS as tens of thousands of staff suffer long Covid https://www.theguardian.com/society/2021/apr/03/nhs-feels-strain-tens-thousands-staff-long-covid "At least 122,000 NHS personnel have the condition, the Office for National Statistics disclosed in a detailed report that showed 1.1 million people in the UK were affected by the condition. That is more than any other occupational group and ahead of teachers, of whom 114,000 have it. Patient care is being hit because many of those struggling with long Covid are only able to work part-time, are too unwell to perform their usual duties, or often need time off because they are in pain, exhausted or have “brain fog”."
  19. It's possible for anyone with the ApoE4 Alzheimer's risk-increasing allele that choline may be beneficial: Droplets of Unsaturated Fats Burden Human ApoE4 Astrocytes https://www.alzforum.org/news/research-news/droplets-unsaturated-fats-burden-human-apoe4-astrocytes "Adding the phospholipid precursor choline to the cells restored their normal lipid metabolism, hinting at potential therapeutic approaches for ApoE4 carriers" "Choline is a component of Souvenaid, a medical food designed by Nutricia of Danone Research to enhance the formation and function of synapses. In the LipiDiDiet clinical trial, people with AD who consumed this yogurt-like drink once a day for two years had slightly less shrinkage of the hippocampus than did controls. The trial failed to meet its primary outcome, but follow-up data suggested that Souvenaid might help people who continue consuming the drink for three years." https://www.alzforum.org/news/conference-coverage/non-av-non-tau-drugs-tweak-markers-cognition-alzheimers-huntingtons "At three years, the cognitive benefit on the CDR-SB widened for those taking Souvenaid, with decline slowing by 45 percent. Likewise, the rate of hippocampal atrophy diverged further between the groups, slowing by 33 percent for those on Souvenaid. The Cohen’s d effect sizes were 0.31 and 0.27, respectively, for CDR-SB and hippocampal atrophy. Both were significant at the 0.01 level or better."
  20. There was also evidence found of cognitive damage in this much larger study from the UK back in October. This was done via online cognitive testing / questionnaire, with a pattern of increasing cognitive damage as Covid severity increased, but even in "mild" cases some cognitive damage was detected. At the higher end of ventilated patients, approximately 8.5 IQ points were estimated lost.

  21. More evidence of brain damage in mild Covid-19 cases, including a pattern of hyperconnectivity that may lead to risk of future issues. "Our findings suggest the new coronavirus affects the brain in individuals who did not require hospitalization, with persistent fatigue, headache, memory problems and somnolence even after two months of their diagnosis. We detected cognitive impairment in these patients, along with white matter abnormalities and hyperconnectivity among distinct resting-state networks. The degree of brain alterations and the severity of cognitive dysfunction raises the attention for the necessity of extensive longitudinal studies of chronic neuropsychiatric symptoms in post-COVID-19 infected individuals. Specific treatment for symptoms and neurorehabilitation strategies may be necessary to improve the quality of life and cognitive function for those with persistent limitations after the acute phase."

    Cake fit for human consumption

    There are some interesting dessert (and other) recipes at this site. The focus is on vegan, gluten-free, processed sugar-free (sweetness typically added via dates), processed oil-free (fats typically added via cashews or other nuts) food: https://plantbasedcookingshow.com/ We've made some of the desserts, muffins, and breads and they generally turn out very tasty. There is an apple pie recipe, haven't tried that one yet: https://plantbasedcookingshow.com/2020/10/03/vegan-apple-pie/
