Nutrition Matters

November 5, 2020 / SupremeCmdr / 4 Comments

By many measures, the population of the United States is the unhealthiest of any high-income country despite spending much more money, as a share of the economy, on health care. The incidence of chronic disease is higher and life expectancy is lower.
Many chronic conditions plaguing Americans, such as obesity, diabetes, and high blood pressure, are avoidable with a prudent diet and lifestyle. Today, more than 42% of American adults have obesity, as do 19.3% of children of age 19 and under. The U.S. has the world’s 12th-highest obesity rate, after Kuwait. (The top 10 are all small Pacific island nations.)
Diet makes a difference. Nearly half of all deaths in the U.S. from heart disease, stroke, and type 2 diabetes are associated with diet, such as the over-consumption of processed meats and sugar-sweetened beverages and insufficient intake of fruits, vegetables, and whole grains.

U.S. election discussion thread — Climate Etc.

I am re-posting this article by Judith Curry. Yes, the headline is somewhat misleading but I’m glad I clicked and read her post. There’s another hurricane coming.

Admit it. We all need a diversion from the election.

More on Vitamin D and Covid-19

November 4, 2020 / SupremeCmdr / 2 Comments

As of this article’s writing, there are over two hundred fifty articles on PubMed about the connection between vitamin D and COVID-19. As the research studies are undergoing, evidence is mounting that adequate vitamin D levels may be a protective factor against COVID-19 infection and severity. Here’s what the research shows.
Is there a role for vitamin D in the treatment of COVID-19? — https://www.kevinmd.com/blog/2020/11/is-there-a-role-for-vitamin-d-in-the-treatment-of-covid-19.html

Yesterday I was going to post a link to an article “Over 80 percent of 200 COVID-19 patients in a hospital in Spain have vitamin D deficiency” when I realized I was unable to access or read the original study. It was late, I was tired, and I didn’t feel like crawling through PubMed to find the study. Well someone out there did the crawling for me. If you follow the link to the original article above you’ll find more links to more research on Vitamin D and Covid-19 like the following:

Evidence suggests that vitamin D supplementation could potentially be effective either in treatment or prevention of coronavirus disease 2019 (Covid‐19). Indeed, several studies and trials have begun to investigate the impact of vitamin D supplementation on patients with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) infection. In this review, we focus on the potential mechanisms of vitamin D in the pathogenesis of Covid‐19. We consider whether deficiency of vitamin D may be one of the underlying biological factors that could explain the excess mortality seen among non‐Caucasians. We also raise several important questions which need to be addressed to provide a clear picture of the extent to which vitamin D supplementation may benefit patients with Covid‐19, particularly those with underlying risk factors.

A little over a month ago I had my annual wellness check up. The medical nerd in me jotted a list of discussion items I wanted to cover during my visit. After catching up on family and checking off the items on my list I asked my doctor if there was anything else she wanted to talk to me about.

No, your list covered all of the things I wanted to talk about except for one. Tell your wife to start taking a Vitamin D supplement.

True story.

Meanwhile in Oklahoma – About That Mask Debate

November 2, 2020 / SupremeCmdr / Leave a comment

Oklahoma Weekly Epidemiology and Surveillance Report 10/23-10/29 2020

In Oklahoma our Governor refuses to mandate masks on a state wide basis. Instead, individual cities and towns decide for themselves whether or not to institute a mask mandate. These numbers don’t lie. Masks work. Wear one.

Vitamin D and Calcium Reduce Incidence of Recurrent Vertigo (BPPV)

November 1, 2020 / SupremeCmdr / 2 Comments

The multi-center study included 957 people in South Korea with benign paroxysmal positional vertigo who had undergone canalith repositioning maneuvers—head movements that shift displaced calcium carbonate crystals in the inner ear. The intervention group included patients who received 400 IU vitamin D and 500 mg calcium carbonate twice daily for 1 year when their baseline serum vitamin D level was below 20 ng/mL along with patients who had higher baseline levels and took no supplements. An observation group had no baseline testing or interventions.
The supplements significantly reduced the annual vertigo recurrence rate by 24%. There were 0.83 recurrences per 1 person-year in the intervention group compared with 1.10 in the observation group. Patients with greater vitamin D deficiencies at baseline derived the most benefit.
JAMA. 2020;324(16):1599. doi:10.1001/jama.2020.18695 — https://jamanetwork.com/journals/jama/fullarticle/2772275

BPPV = benign paroxysmal positional vertigo. The original study in Neurology and the JAMA summary both use the word “prevent” in their respective titles. I think reduce is a more apt description. Semantics aside a 24% reduction in recurrent BPPV episodes is significant.

And yet another example of nutritional deficiencies underlying another disease.

Older Adults Living with Younger People Face Increased Risk for COVID-19 Mortality (if you’re Swedish)

November 1, 2020October 31, 2020 / SupremeCmdr / Leave a comment

Older adults who live with younger people, including those of working age, are at increased risk for COVID-19 mortality, according to a study in The Lancet Healthy Longevity.
Using Swedish population and death registries, researchers studied nearly 275,000 adults aged 70 or older in Stockholm. Roughly 3400 died between March and May 2020, 38% from COVID-19.
Those who lived with at least one person younger than 66 years had a 60% increased risk for COVID-19 death relative to those living with older people. In addition, those living in the most densely populated neighborhoods had a 70% higher risk than those in the least densely populated areas, and those living in care homes had over four times the risk of those in independent housing.

Check out the recent Time article for an excellent overview of the Swedish Covid-19 response:

The Swedish way has yielded little but death and misery. And, this situation has not been honestly portrayed to the Swedish people or to the rest of the world.

Meanwhile in Houston D614G Mutation – 10.31.20

October 31, 2020 / SupremeCmdr / 1 Comment

During the initial wave of the pandemic, 71% of the novel coronaviruses identified in patients in Houston had this mutation. When the second wave of the outbreak hit Houston during the summer, this variant had leaped to 99.9% prevalence. This mirrors a trend observed around the world. A study published in July based on more than 28,000 genome sequences found that variants carrying the D614G mutation became the globally dominant form of SARS-CoV-2 in about a month. SARS-CoV-2 is the coronavirus that causes COVID-19.
University of Texas at Austin – https://medicalxpress.com/news/2020-10-coronavirus-mutation-contagious.html — More information: Molecular Architecture of Early Dissemination and Massive Second Wave of the SARS-CoV-2 Virus in a Major Metropolitan Area, mBIO, DOI: 10.1128/mBio.02707-20 , mbio.asm.org/content/11/6/e02707-20

Kind of spooky if you ask me.

Covid-19 in the House? The CDC Says Do This

October 31, 2020October 31, 2020 / SupremeCmdr / 3 Comments

Forty percent (41 of 102) of infected household members reported symptoms at the time SARS-CoV-2 was first detected by RT-PCR. During 7 days of follow-up, 67% (68 of 102) of infected household members reported symptoms, which began a median of 4 days (IQR = 3–5) after the index patient’s illness onset. The rates of symptomatic and asymptomatic laboratory-confirmed SARS-CoV-2 infection among household members was 36% (95% CI = 29%–43%) and 18% (95% CI = 13%–24%), respectively.
Because prompt isolation of persons with COVID-19 can reduce household transmission, persons who suspect that they might have COVID-19 should isolate, stay at home, and use a separate bedroom and bathroom if feasible. Isolation should begin before seeking testing and before test results become available because delaying isolation until confirmation of infection could miss an opportunity to reduce transmission to others. Concurrently, all household members, including the index patient, should start wearing a mask in the home, particularly in shared spaces where appropriate distancing is not possible. Close household contacts of the index patient should also self-quarantine, to the extent possible, particularly staying away from those at higher risk of getting severe COVID-19. To complement these measures within the household, a potential approach to reduce SARS-CoV-2 transmission at the community level would involve detecting infections before onset of clinical manifestations; this would require frequent and systematic testing in the community with rapidly available results to enable prompt adoption of preventive measures. The feasibility and practicality of this approach is undergoing extensive discussion (9) and study. This ongoing household transmission study will provide critical data regarding the recommended timing and frequency of testing.

I was in the grocery store yesterday and The Defiant Ones were obvious. Granted the majority of the shoppers were wearing masks, mandatory by city decree. But The Defiant Ones were strutting about mask-less not caring whether or not they infected others or potentially get infected themselves. It’s going to be a long, hard cold winter.

Update:

After posting my perspective on The Defiant Ones I stumbled upon a small (n=104) study on grocery store workers. Here are the key findings:

The present study fills in the knowledge gap of COVID-19 impacts on grocery/retail market workers during the pandemic, from both physical and psychological perspectives.
In this single store sample (n=104), we found an alarming infection rate of 20% positive SARS-CoV-2 RT-PCR assay result among these workers and the majority (76%) of them were asymptomatic at the time of testing.
Furthermore, employees with direct customer exposure were five times more likely to test positive for SARS-CoV-2.
Our study also found the inability to practice social distancing consistently at work was a significant risk factor for anxiety and depression.
At the same time, commuting to work by public transportation/shared rides was significantly associated with depressive state.

I wonder if any of The Defiant Ones know about this study?
