A recent study by Johns Hopkins Medicine researchers provides evidence that CD4+ T lymphocytes—immune system cells also known as helper T cells—produced by people who received either of the two available messenger RNA (mRNA) vaccines for COVID-19 persist six months after vaccination at only slightly reduced levels from two weeks after vaccination and are at […]
As COVID-19 breakthrough infections continue to emerge in some vaccine recipients and health authorities are developing policies around booster vaccinations, national data on COVID-19 vaccine breakthrough infections is inadequate but urgently needed. Now a study from the Public Health Institute, the Veterans Affairs Medical Center and the University of Texas Health Science Center, published today […]
Over 28 million more years of life were lost than expected in 2020 in 31 upper-middle and high-income countries, finds a study published by The BMJ today. Except for Taiwan, New Zealand, Denmark, Iceland, Norway, and South Korea, all other countries examined had more premature deaths than expected in 2020, with a higher rate in […]
A nationwide study of over 1 million births in the English National Health Service (NHS) between 2015 and 2017, published in The Lancet, has found large inequalities in pregnancy outcomes between ethnic and socioeconomic groups in England. The findings suggest that current national programmes to make pregnancy safer, which focus on individual women’s risk and […]
New research addresses ongoing concerns regarding risks of allergic reactions after receiving mRNA COVID-19 vaccines, particularly for individuals with a history of severe allergic reactions. The JAMA Network Open study of employee vaccinations within the Mass General Brigham health care system revealed that although people with such a history reported more allergic symptoms after vaccination, […]
Mental health problems are common among adults who smoke cigarettes and those with substance use disorders, illustrating a need for treating smoking and mental health problems together, according to a new study by Indiana University. The research, done in conjunction with other universities, found mental health problems were more than twice as common among adults […]
Past research suggests that brain oscillations may support different cognitive functions by coordinating spike timing inside and across different brain regions. However, the role that the timing of these oscillations plays in specific neural computations is still unclear. Researchers at University of California, San Diego carried out a study investigating the role of theta oscillations […]
New research from the University of Virginia School of Medicine quantifies the antibody response generated by the Pfizer and Moderna COVID vaccines. The findings are some of the earliest to compare the two vaccines’ antibody responses head-to-head. The notable finding was that antibody levels in recipients of the Moderna vaccine were slightly higher than in […]
Chronic pain is a debilitating condition affecting millions of people worldwide. An improved understanding of the pathophysiology of chronic pain is urgently needed. A study by the Ganter Lab, recently published in Molecular Pain, a peer-reviewed open access medical journal covering all aspects of research on pain, helped to fill that need. The study, aimed […]
An analysis of data from 1.5 million people has identified 579 locations in the genome associated with a predisposition to different behaviors and disorders related to self-regulation, including addiction and child behavioral problems. With these findings, researchers have constructed a genetic risk score—a number reflecting a person’s overall genetic propensity based on how many risk […]
