Vitamin D Deficiency Is Inversely Associated with COVID-19 Incidence and Disease Severity in Chinese People

In the general linear model adjusted for age, sex, comorbidities, and BMI, serum 25(OH)D concentrations were significantly lower among COVID-19 patients than the 2018–2019 controls [ln transformed values of 3.32 ± 0.04 vs. 3.46 ± 0.022 ln (nmol/L), = 0.014]. Multivariable logistic regression showed that male sex (OR: 2.26; 95% CI: 1.06, 4.82), advanced age (≥65 y) (OR: 4.93; 95% CI: 1.44, 16.9), and vitamin D deficiency (<30 nmol/L) (OR: 2.72; 95% CI: 1.23, 6.01) were significantly associated with COVID-19 severity (all < 0.05).

These findings suggested that vitamin D deficiency impacts COVID-19 hospitalization and severity in the Chinese population.

I would not take Covaxin without efficacy data: Gagandeep Kang — Science Chronicle

Serum’s Covishield and Bharat Biotech’s Covaxin are examples of atmanirbhar (self-reliance) but have an element of non-Indian science — and at least to me that is fine, says Dr. Gagandeep Kang. Though Covaxin uses inactivated virus, neutralising antibodies against the spike protein are critical for reinfection. So if Covaxin is based on an old viral […]

More on Colleges and Covid

U.S. counties with large colleges or universities with remote instruction (n = 22) experienced a 17.9% decrease in incidence and university counties with in-person instruction (n = 79) experienced a 56% increase in incidence, comparing the 21-day periods before and after classes started. Counties without large colleges or universities (n = 3,009) experienced a 6% decrease in incidence during similar time frames.

Outdoor experts agree, risk management is key

So, it might not come as a shock that after this past year Colorado Parks and Wildlife reported a 30 percent increase in visitations through Nov. 2020, as noted by the Denver Post; a staggering number considering that just one year prior, the Outdoor Foundation reported that nearly half of the U.S. population did not participate in outdoor recreation.The Roaring Fork Valley (RFV) is no outlier to this outdoor participation trend, and with more travel and a dangerous snowpack this season, the risks are intensified. Fortunately, outdoor leaders in the RFV have noticed that recreationists are taking risk management – the ability to independently assess the risks of an activity – seriously.

Increase in pleasurable effects of alcohol over time can predict alcohol use disorder

A new study out of the University of Chicago Medicine following young adult drinkers for 10 years has found that individuals who reported the highest sensitivity to alcohol’s pleasurable and rewarding effects at the start of the trial were more likely to develop an alcohol use disorder (AUD) over the course of the study.

CDC reports more allergic reactions to Covid-19 vaccines, but cases remain few

The Centers for Disease Control and Prevention said at present it looks like anaphylaxis cases are occurring at a rate of about 5.5 per 1 million vaccine doses given, though the agency cautioned that figure may change as the vaccination effort continues.

The allergic reactions do not change CDC’s recommendations on who can be vaccinated against Covid-19, with senior officials stressing that the risk of severe illness and death from the disease still outweighs the risk of developing anaphylaxis after vaccination.

Kaiser San Jose Covid Outbreak

Hospital officials initially reported an outbreak of 44 infections traced back to the apparently impromptu Christmas celebration, but this would be the first fatality associated with the informal Dec. 25 visit. All 44, including the employee who died, had been working in the emergency department that day, according to NBC Bay Area, which also described the outbreak’s first victim as a woman who worked as a registration clerk in the department.

Vitamin D – What’s Your Level?

“Our trends this year are dramatically different than previous years’ in that they’re far less fleeting. COVID-19 is a pandemic that sits on top of another pandemic in the United States of malnutrition and poor long-term health,” remarked Shelby Miller, MS, Natural Grocers’ Manager of Scientific Affairs and Nutrition Education. “Hence, 2021 holds broader trends that focus on improving nutrition to support our own health, as well as the health of our communities and our environment.”

While there are many things in life outside of our control, knowing our vitamin D levels is a simple step we can all take to elevate our health and the health of our families—it is something you can own as a proactive tool to be rooted in health. This unique nutrient plays a critical role in whether or not your immune system functions sufficiently and responds as needed. It is essential for lung health, supporting positive moods, brain function, and cognition, a healthy weight, a healthy pregnancy, children’s health, healthy blood sugar levels, healthy blood pressure, bone health, and muscle tone. Between 40 and 80 percent of American adults are outright deficient in vitamin D, while approximately 90 percent have sub-optimal levels. Achieving optimal levels (between 30 and 50 ng/mL) of vitamin D through supplementation is crucial to experiencing its full range of benefits. Because darker skin hampers the body’s ability to synthesize vitamin D from sunlight, supplementation is especially important for people of color. A national survey reported average serum vitamin D concentrations of 28.1 ng/mL, 21.6 ng/mL, and 16.9 ng/mL in Caucasian, Mexican American, and African American adults aged 20 years and older, respectively. Vitamin D is a nutrient all of us should be focused on, and we all need to know our levels, but this is especially important for those with darker complexions.

I have no financial relationship with Natural Grocers nor do I shop at their stores often. We get the company’s sales brochure via Snail Mail and when I read the #1 predicted trend for 2021 was Vitamin D supplementation I had to pass it along (with proper attribution). On a personal note I started supplementing with Vitamin D around 7-8 years ago. I was satisfied with my research and figured this was an easy behavioral change. Besides, Vitamin D supplements were (and still are) cheap and widely available.

The Boss and I share the same personal physician. At my last wellness check she looked me in the eye and said,

“Tell you wife to take a Vitamin D supplement.”

True story. BTW my last level was 38 ng/mL. A few more of my posts on Vitamin D are listed below.

Nosocomial Covid-19 Infections

Regrettably, covid-19 among hospital staff is common even after all the precautions with masks, shields and other personal protective equipment. Studies show that front-line health-care workers in the United States have a covid-positive rate that is four times greater than the general population.

Tracking Covid mortality in healthcare workers is imprecise for a number of reasons. Any estimates are likely to be lower than the true number.

More than 2,900 US healthcare workers have died in the Covid-19 pandemic since March, a far higher number than that reported by the government, according to a new analysis by the Guardian and KHN.
