Among people who have the most common type of lung cancer, up to 40% develop metastatic brain tumors, with an average survival time of less than six months.
Researchers at Wake Forest School of Medicine have discovered that nicotine promotes the spread of lung cancer cells into the brain, where they can form deadly metastatic tumors. The study, which will be published June 4 in the Journal of Experimental Medicine (JEM), suggests that nicotine replacement therapies may not be suitable strategies for lung cancer patients attempting to quit smoking. In addition, the researchers show that the naturally occurring drug parthenolide blocks nicotine-induced brain metastasis in mice, suggesting a potential therapeutic option in humans.
Chronic stress is associated with the pathogenesis of psychological disorders such as depression. A study is the first to identify the role of a neuronal receptor that straddles the intersection between social stress, inflammation, and anxiety in rodent models of stress. Findings suggest the possibility of developing better medications to treat the consequences of chronic stress by limiting inflammatory signaling not just generally, which may not be beneficial in the long run, but to specific brain circuits.
The COVID Research Program is rapidly enrolling patients from New Jersey, which has one of the world’s highest concentrations of COVID-19 patients. Atlantic Health System offers a study sponsored by TScan Therapeutics, Inc., a leading T cell therapeutics company in Waltham, Massachusetts, focused on identifying the precise way the human immune system recognizes and responds to infections like COVID-19 or other diseases, like cancers. TScan has developed a novel technology that enables them to identify the natural targets of T cells.

To study the brain “in action,” researchers use a specialized form of brain imaging known as task-based functional MRI (task-fMRI), which shows how the brain responds to stimuli. While this technique can reveal much about the general workings of the average human brain, new research indicates that task-fMRI lacks the reliability to predict individual behavior or how a person might respond to mental-health therapies.
The jury’s still out on whether the use of marijuana may increase the risk of stroke. While several larger studies have found an increased risk, other studies have found no such increased risk. Adding to the debate is a new study that looked at recent marijuana use and risk of ischemic stroke published in the June 3, 2020, online issue of Neurology® Clinical Practice.

The National Eye Institute (NEI) has funded development of a handheld pediatric vision scanner that easily and accurately screens for amblyopia, or “lazy eye.” The device could facilitate earlier identification of children who need vision-saving treatment when therapy is likely to be more effective. It also could reduce unnecessary referrals to ophthalmologists.
Turning to a tub of ice cream after a break-up may be a cliché, but there's some truth to eating in response to negative emotions. Eating serves many functions - survival, pleasure, comfort, as well as a response to stress.
Irvine, Calif., June 3, 2020 — “We’re all in this together” is a commonly heard phrase during this global pandemic, as much of the world practices social distancing. And now researchers at the University of California, Irvine and other institutions have shown that there is some scientific validity to this assertion. In a study published today in Nature Human Behaviour, Chinese, European, American and British researchers demonstrate that the number of countries implementing COVID-19 lockdown measures – and the duration of those efforts – have a greater influence on the gross domestic products of nations than the severity of the restrictions.
A new survey conducted during the pandemic by researchers at the Johns Hopkins Bloomberg School of Public Health and the SNF Agora Institute at Johns Hopkins University found a more-than-threefold increase in the percentage of U.S. adults who reported symptoms of psychological distress—from 3.9 percent in 2018 to 13.6 percent in April 2020.
As health care facilities resume operations paused due to COVID-19, a new survey shows many people are reluctant to undergo procedures and may not reschedule necessary care while COVID-19 continues to circulate in communities. To help surgeons and hospitals address patient concerns, ACS has released a new resource document.
Researchers urge a moratorium on prescribing chloroquine or hydroxychloroquine, with or without azithromycin, to treat or prevent COVID-19, and caution that the reassuring safety profile of hydroxychloroquine may be more apparent than real. Safety data derive from decades of prescriptions by clinicians, primarily for their patients with lupus and rheumatoid arthritis, both of which are of greater prevalence in younger and middle age women, who are at very low risk of fatal heart outcomes due to hydroxychloroquine.
A review of 56 randomized clinical trials finds that psychological and behavioral therapies may be effective non-drug treatments for reducing disease-causing inflammation in the body.
Yale Cancer Center scientists have identified mutations in metabolite-producing genes as a disruption of DNA repair. These mutation-driven “oncometabolites” may make cells more prone to developing cancer—but also more vulnerable to new cancer treatment strategies.
The hypothalamic–pituitary–adrenal (HPA) axis is the body’s key stress response system. By driving production of the stress hormone cortisol, and then ensuring a return to baseline levels, the HPA axis regulates our reaction to stressful events. Chronic alcohol use, however, can lead to persistently elevated cortisol, reducing the body’s capacity to respond appropriately to stress. Among people in treatment for alcohol use disorder (AUD), the blunted stress response predicts risk of relapse and a return to drinking. Longer-term life stress, including childhood adversity, post-traumatic stress disorder (PTSD), and chronic stress, can also dampen HPA axis function, complicating interpretation of the alterations evident in people with AUD. However, it is not known how stress and trauma intereact with AUD to affect HPA-axis reactivity. A new report in Alcoholism: Clinical and Experimental Research by researchers from the universities of Texas, Florida, and Colorado addresses this issue, u
