Nicholas Christakis is director of the Human Nature Lab at Yale University and author of the bestseller "Apollo’s Arrow." He speaks with Hari Sreenivasan about the next phase of the pandemic based on previous pandemics.

Molnupiravir was associated with a decreased the risk of hospitalization from Covid-19 by only 30%, compared to a reduction of almost 90% with Pfizer's PAXLOVID. The FDA advisory committee also limited its use in non-pregnant adults because of their concerns about the potential risk of mutations in human DNA.

A computational biologist thinks potentially half the globe may contract Omicron over the coming weeks and months.

The omicron wave appears to have peaked and is already subsiding in South Africa, with a relatively minor impact on their healthcare system. However, the positive rate is still around 29%, suggesting high circulation among their population. other fluctuations.

Omicron is now the most common variant among new Covid cases in the U.S., accounting for nearly three-quarters of new infections.

Research shows an increased potential for spread through aerosols.

Matt, Dara, Jerusalem, and German use Matt’s last Tuesday episode to discuss life expectancy in the US. They explore paternalistic policy decisions, the misnomer of “deaths of despair,” and the longevity of The Weeds.

A Yale study finds older people living in less advantaged neighborhoods become disabled roughly two years earlier than their more affluent counterparts.

The anti-vax fertility panic, explained.

Background: Population age structure may confound the comparison of age at cancer diagnosis across racial/ethnic groups. We compared age at cancer diagnosis for U.S. Hispanics, a population that is younger on average, and non-Hispanic whites (NHW), before and after adjustment for the age structure of the source population. Methods: We used Surveillance, Epidemiology, and End Results data from 18 U.S. regions in 2015 for 34 cancer sites to calculate crude and adjusted (using age- and sex-specific weights) mean ages at diagnosis. Differences in age at diagnosis comparing Hispanics to NHWs ( δ ) were assessed using independent sample t tests. Results: Crude mean ages at diagnosis were lower among Hispanic males and females for all sites combined and for most cancer sites. After age-adjustment, Hispanic (vs. NHW) males remained younger on average at diagnosis of chronic myeloid leukemia [ δ = −6.1; 95% confidence interval (CI), −8.1 to −4.1 years], testicular cancer ( δ =−4.7; 95% CI, −5.4 to −4.0), Kaposi sarcoma ( δ =−3.6; 95% CI,−6.3 to −0.8), mesothelioma ( δ =−3.0; 95% CI,−4.3 to −1.7), and anal cancer ( δ =−2.4; 95% CI, −3.9 to −0.8), and older at diagnosis of gallbladder cancer (δ = +3.8; 95% CI, 1.8 to 5.7) and Hodgkin's lymphoma ( δ = +7.5; 95% CI, 5.7 to 9.4), and Hispanic (vs. NHW) females remained younger at diagnosis of mesothelioma ( δ = −3.7; 95% CI, −6.7 to −0.7) and gallbladder cancer ( δ = −3.0; 95% CI, −4.3 to −1.7) and older at diagnosis of skin cancer ( δ = +3.8; 95% CI, 3.1 to 4.5), cervical cancer ( δ = +4.1; 95% CI, 3.3 to 4.8), and Hodgkin's lymphoma ( δ = +7.0; 95% CI, 5.0 to 9.1). Conclusions: On average, Hispanics are diagnosed with cancer at younger ages than NHWs; however, for many cancers these differences reflect the younger age structure in Hispanics. Impact: Population age structure should be considered when comparing age at cancer diagnosis across racial/ethnic groups.

Cases have been reported in the United States, Colombia, Japan, South Korea and parts of Europe.

Polypharmacy — taking five or more meds at a time — leads to side effects, unnecessary hospitalizations and premature deaths. Researchers and pharmacists are seeking solutions to this serious public health problem that disproportionately affects older adults.
