Calling on All of Us Public Health Scientists
MJ Khoury et al, CDC Blog Post, July 22, 2022 Brand

Scientists at the Centers for Disease Control and Prevention and elsewhere can now access and analyze data from the National Institutes of Health’s All of Us Research Program. In this post, we briefly explore three attributes of All of Us data that make them uniquely beneficial for public health scientists and other researchers interested in population health.

Prediction of COVID-19 Data Using Hybrid Modeling Approaches

The Role of Children in SARS-CoV-2 Variant of Concerns Transmission within Households: A Meta-analysis
Y Zuo et al, MEDRXIV, July 22, 2022

We perform a meta-analysis of the role of children in the household transmission of both ancestral SARS-CoV-2 and SARS-CoV-2 VOCs. Unlike the ancestral virus, children infected with VOCs spread SARS-CoV-2 to an equivalent number of household contacts as infected adults. Similarly, unlike the ancestral virus, children within a household were equally as likely as adults to acquire SARS-CoV-2 from an infected family member. Interestingly, this same observation was noted when unvaccinated children exposed to VOCs were compared to unvaccinated adults exposed to VOCs. Together, these data suggest that the emergence of VOCs were associated with a fundamental shift in the epidemiology of SARS-CoV-2.

The Effect of SARS-COV-2 Variant on Respiratory Features and Mortality Among Vaccinated and Non-Fully Vaccinated Patients
TD Hughes et al, MEDRXIV, July 22, 2022

A retrospective review of medical records (n=63,454 unique patients) using The University of California Health COvid Research Data Set (UC CORDS) was performed to identify respiratory features, vaccination status, and mortality. Variants were identified using the CDC data tracker. Results. Increased odds of death were observed among those not fully vaccinated (Delta OR: 1.64, p = 0.052; Omicron OR: 1.96, p < 0.01). Later variants (i.e., Delta and Omicron) demonstrated a reduction in the frequency of lower respiratory tract features with a concomitant increase in upper respiratory tract features. Vaccination status was associated with survival and a decrease in the frequency of many upper and lower respiratory tract features.

Analysis of Whole-Genome Sequencing of SARS-CoV-2 Reveals Recurrent Mutations among Iranian Patients

The deceptive simplicity of mendelian genetics.
McLysaght Aoife et al. PLoS biology 2022 7 (7) e3001691

Mendel, a genius experimentalist, meticulously uncovered the genetic basis of heredity in work that transformed the science of biology. But does the alluring simplicity of Mendel’s laws sometimes obscure the true complexity of genetics? We are not mere vessels for our genes. Humans, uniquely, and starting with Mendel, are the only species that has developed an understanding of heredity and how genetic information is transmitted across generations and how genes help shape all biological life on this planet. Though we describe supposed single-gene deterministic traits as “mendelian,” I know of no evidence that suggests Mendel himself conceived of such a fanciful system.
