Going Once? Going Twice? Vaccinated!
CDC COVID Data Tracker Weekly Review, May 7, 2021 Brand (Posted: May-07-2021 2PM)

While more than 8 in 10 people 65 years and older have received at least one dose of vaccine, only around 1 in 3 people ages 18-29 have. All age groups currently eligible for the vaccine can benefit from the protection it provides themselves and others, especially as more states are easing prevention measures.


Genome-wide survival study identifies a novel synaptic locus and polygenic score for cognitive progression in Parkinson’s disease
G Liu et al, Nature Genetics, May 6, 2021 (Posted: May-07-2021 10AM)

We performed a longitudinal genome-wide survival study of 11.2 million variants in 3,821 patients with PD over 31,053 visits. We discover RIMS2 as a progression locus and confirm this in a replicate population (hazard ratio (HR)?=?4.77, P?=?2.78?×?10-11), identify suggestive evidence for TMEM108 (HR?=?2.86, P?=?2.09?×?10-8) and WWOX (HR?=?2.12, P?=?2.37?×?10-8) as progression loci, and confirm associations for GBA (HR?=?1.93, P?=?0.0002) and APOE (HR?=?1.48, P?=?0.001). Polygenic progression scores exhibit a substantial aggregate association with dementia risk.

Shinde Vivek et al. The New England journal of medicine 2021 5 (Posted: May-06-2021 7AM)

Vaccine efficacy among HIV-negative participants was 60.1% (95% CI, 19.9 to 80.1). Of 41 sequenced isolates, 38 (92.7%) were the B.1.351 variant. Post hoc vaccine efficacy against B.1.351 was 51.0% (95% CI, -0.6 to 76.2) among the HIV-negative participants. Preliminary local and systemic reactogenicity events were more common in the vaccine group; serious adverse events were rare in both groups.


Effectiveness of the BNT162b2 Covid-19 Vaccine against the B.1.1.7 and B.1.351 Variants.
Abu-Raddad Laith J et al. The New England journal of medicine 2021 5 (Posted: May-06-2021 7AM)

The estimated effectiveness of the vaccine against any documented infection with the B.1.1.7 variant was 89.5% (95% confidence interval [CI], 85.9 to 92.3) at 14 or more days after the second dose (Table 1 and Table S2). The effectiveness against any documented infection with the B.1.351 variant was 75.0% (95% CI, 70.5 to 78.9). Vaccine effectiveness against severe, critical, or fatal disease due to infection with any SARS-CoV-2 (with the B.1.1.7 and B.1.351 variants being predominant within Qatar) was very high, at 97.4% (95% CI, 92.2 to 99.5).


Interplay between Emerging SARS-CoV-2 Variants and Pandemic Control.
Neuzil Kathleen M et al. The New England journal of medicine 2021 5 (Posted: May-06-2021 7AM)

The emergence of variant strains is arguably the greatest threat to control of the Covid-19 pandemic. A coordinated global prevention-and-control plan is the only way forward. Global investments in vaccine science and technology must be accompanied by investments in public health, genomic and disease surveillance, and programmatic immunization infrastructure to mitigate the effects of Covid-19 and future pandemics.

Modeling of Future COVID-19 Cases, Hospitalizations, and Deaths, by Vaccination Rates and Nonpharmaceutical Intervention Scenarios — United States, April–September 2021
RK Borchering et al, MMWR, May 5, 2021 (Posted: May-05-2021 11AM)

Data from six models indicate that with high vaccination coverage and moderate NPI adherence, hospitalizations and deaths will likely remain low nationally, with a sharp decline in cases projected by July 2021. Lower NPI adherence could lead to substantial increases in severe COVID-19 outcomes, even with improved vaccination coverage.


Identification of and Surveillance for the SARS-CoV-2 Variants B.1.427 and B.1.429 — Colorado, January–March 2021
LM Webb et al, CDC MMWR, May 5, 2021 (Posted: May-05-2021 11AM)

B.1.427/B.1.429 case sequences were identified a median of 14.5 days after specimen collection (range = 7–38 days). Median patient age was 39 years (range = <1–95 years); 186 (57%) patients were male. Cases were identified in 31 (48%) of Colorado’s 64 counties. Enhanced interviewing of all patients with variant cases was attempted through February; 60 (83%) such interviews were completed. Among these, nine (15%) persons reported travel outside Colorado


Rapid Emergence and Epidemiologic Characteristics of the SARS-CoV-2 B.1.526 Variant — New York City, New York, January 1–April 5, 2021
CN THompson et al, CDC MMWR, May 5, 2021 (Posted: May-05-2021 11AM)

The NYC Department of Health and Mental Hygiene analyzed laboratory and epidemiologic data to characterize cases of B.1.526 infection and the associated potential for breakthrough infection and reinfection. Preliminary evidence suggests that, to date, B.1.526 does not lead to more severe disease or increased risk for infection after vaccination. Rapid integration of whole genome sequencing and population-based surveillance data is critical to characterizing new SARS-CoV-2 variants.


SARS-CoV-2 Variant Classifications and Definitions
CDC, May 5, 2021 (Posted: May-05-2021 11AM)

A US government interagency group developed a Variant Classification scheme that defines three classes of SARS-CoV-2 variants: variant of interest, variant of concern, variant of high consequence. The B.1.526, B.1.526.1, B.1.525, B.1.617, B.1.617.1, B.1.617.2, B.1.617.3, and P.2 variants circulating in the United States are classified as variants of interest. The B.1.1.7, B.1.351, P.1, B.1.427, and B.1.429 variants circulating in the United States are classified as variants of concern. To date, no variants of high consequence have been identified in the United States.

TR Mercer et al, Nature Rev Genetics, May 4, 2021 (Posted: May-04-2021 3PM)

This Review describes the changing role of testing during the COVID-19 pandemic, including the use of genomic surveillance to track SARS-CoV-2 transmission around the world, the use of contact tracing to contain disease outbreaks and testing for the presence of the virus circulating in the environment. Despite these efforts, widespread community transmission has become entrenched in many countries and has required the testing of populations to identify and isolate infected individuals, many of whom are asymptomatic.


Ensuring that biomedical AI benefits diverse populations
J Zhou et al, E Biomedicine, May 4, 2021 (Posted: May-04-2021 3PM)

Artificial Intelligence (AI) can potentially impact many aspects of human health, from basic research discovery to individual health assessment. It is critical that these advances in technology broadly benefit diverse populations from around the world. This can be challenging because AI algorithms are often developed on non-representative samples and evaluated based on narrow metrics. Here we outline key challenges to biomedical AI in outcome design, data collection and technology evaluation, and use examples from precision health to illustrate how bias and health disparity may arise.

Prior SARS-CoV-2 infection rescues B and T cell responses to variants after first vaccine dose
CJ Reynolds et al, Science, April 23, 2021 (Posted: Apr-30-2021 7PM)

We analyzed T and B cell responses after first dose vaccination with the Pfizer/BioNTech mRNA vaccine BNT162b2 in healthcare workers (HCW) followed longitudinally, with or without prior Wuhan-Hu-1 SARS-CoV-2 infection. After one dose, individuals with prior infection showed enhanced T cell immunity, antibody secreting memory B cell response to spike and neutralizing antibodies effective against B.1.1.7 and B.1.351. By comparison, HCW receiving one vaccine dose without prior infection showed reduced immunity against variants. B.1.1.7 and B.1.351 spike mutations resulted in increased, abrogated or unchanged T cell responses depending on human leukocyte antigen (HLA) polymorphisms

JC Melms et al, Nature, April 29, 2021 (Posted: Apr-29-2021 11AM)

Respiratory failure is the leading cause of death in patients with severe SARS-CoV-2 infection1,2, yet the host response at the lung tissue-level is poorly understood. Here, we performed single-nucleus RNA-sequencing of ~116,000 nuclei of lungs from 19 COVID-19 decedents who underwent rapid autopsy and 7 control lungs. Integrated analyses revealed significant alterations in cellular composition, transcriptional cell states, and cell-to-cell interactions, providing insights into the biology of lethal COVID-19.


Milestone stem cell transplant helps child beat rare disease
D Sashin, Stanford Scope, April 28, 2021 (Posted: Apr-29-2021 10AM)

Nine-year-old Shriya recently learned to ride a scooter. That was a big deal for a girl who, not so long ago, spent 14 hours a day on dialysis for kidney failure and could run only a few steps before getting tired. Every parent thinks their child is one in a million, but Shriya truly is. She was born with Schimke immuno-osseous dysplasia, a genetic, multisystem disorder affecting just one in a million children in North America. Children with the disease have shortened limbs and trunks, immune system problems and kidney disease. They historically have lived an average of nine years.

Glucose-6-phosphate dehydrogenase activity in individuals with and without malaria: Analysis of clinical trial, cross-sectional and case-control data from Bangladesh.
Ley Benedikt et al. PLoS medicine 2021 4 (4) e1003576 (Posted: Apr-28-2021 11AM)

Patients with acute malaria had significantly higher G6PD activity than individuals without malaria, and this could not be accounted for by a protective effect of G6PD deficiency. G6PD-deficient patients with malaria may have higher than expected G6PD enzyme activity and an attenuated risk of primaquine-induced hemolysis compared to the risk when not infected.

Genomic Epidemiology of SARS-CoV-2 Infection During the Initial Pandemic Wave and Association With Disease Severity
FP Esper et al, JAMA Network Open, April 26, 2021 (Posted: Apr-26-2021 11AM)

Within weeks of SARS-CoV-2 circulation, a profound shift toward 23403A>G (D614G) specific genotypes occurred. Replaced clades were associated with worse clinical outcomes, including mortality. These findings help explain persistent hospitalization yet decreasing mortality as the pandemic progresses. SARS-CoV-2 clade assignment is an important factor that may aid in estimating patient outcomes.
