UNIVERSITY PARK, Pa. — This summer, viral misinformation claimed that the Amish did not vaccinate against COVID-19 and, as a result, had a death rate 90 times lower than the rest of the United States. Now, a Penn State study is the first to provide geographically broad and population-wide evidence that while the Amish-populated counties across the nation tend to have lower vaccination rates than other populations, they are not entirely unvaccinated.  The research was published recently in the journal Population Research and Policy Review. The Amish are a distinctive Christian subculture that traces its roots to the 16th century Protestant ...

A recent article published in Volume 3 of the journal Psychoradiology, researchers from Sichuan Normal University introduced an innovative Three-Choice BIC paradigm that merges the GNG and two-choice oddball (TCO) tasks. This study engaged 48 college students who responded to varied stimuli using designated keys and restrained responses to no-go stimuli. Employing functional neuroimaging coupled with conjunction and ROI analyses, the researchers sought to unveil unique neural pathways linked to BIC ...

ROCHESTER, Minn. — The treadmill exercise test with electrocardiogram (ECG), also known as an exercise stress test, is one of the most familiar tests in medicine. While exercise testing typically is focused on diagnosing coronary artery disease, a recent study from Mayo Clinic finds that exercise test abnormalities, such as low functional aerobic capacity, predicted non-cardiovascular causes of death such as cancer in addition to cardiovascular-related deaths. These new findings are published in Mayo Clinic Proceedings. The exercise stress test is noninvasive, easily available and provides important diagnostic information. In addition to the ECG itself, ...

DENVER/Sept. 6, 2023 — A newly funded study will evaluate both the frequency and major risk factors for cancer in golden retrievers, a breed commonly affected by the disease.   The study will use data from Morris Animal Foundation’s Golden Retriever Lifetime Study, which is one of the largest and most comprehensive canine health studies in the world. The study will also incorporate data from Veterinary Companion Animal Surveillance System (VetCompass), a not-for-profit research project based at the Royal Veterinary College ...

LA JOLLA, CA—A good night’s sleep has many proven health benefits, and a new Scripps Research study suggests one more: preventing opioid relapse. In the new study, published online in Neuropharmacology on August 12, 2023, scientists gave an experimental insomnia treatment to rats experiencing oxycodone withdrawal. The researchers found that the animals were far less likely to seek out drugs again in the future—even after ending the treatment. These findings could eventually lead to therapies to help prevent opioid addiction or relapse in humans. “These results are very encouraging,” says Rémi Martin-Fardon, PhD, associate professor of molecular medicine ...

The researchers studied birds given a simulated bacterial infection in order to stimulate their immune system. The birds were then compared with birds whose immune system was not stimulated – and their activity was measured for several weeks using miniature data loggers. “We found that the birds whose immune system was stimulated had reduced activity for three weeks, which is much longer than we expected. We could also see that the "sick" blackbirds stopped their activities ...

The 2023 edition of the António Champalimaud Vision Award recognizes the St John of Jerusalem Eye Hospital Group (SJEHG) for its work supporting hundreds of thousands of people living in the Gaza Strip, West Bank and East Jerusalem, helping in the fight against blindness while providing access to essential health services in a region marked by conflict and instability. The SJEHG has been developing its activity at the centre of three major world religions. The ongoing conflict in the region has had a severe impact on health care access and delivery. Without the intervention of the SJEHG, the rate of blindness would be rampant, increasing ...

New “hypervirulent” strains of the bacterium Klebsiella pneumoniae have emerged in healthy people in community settings, prompting a National Institutes of Health research group to investigate how the human immune system defends against infection. After exposing the strains to components of the human immune system in a laboratory “test tube” setting, scientists found that some strains were more likely to survive in blood and serum than others, and that neutrophils (white blood cells) are more likely to ingest and kill some strains than others. The study, published in mBio, was led by researchers at NIH’s National Institute of Allergy and Infectious Diseases (NIAID). “This ...

RIVERSIDE, Calif. -- It came as a surprise to Professor David Lo and his graduate student Diana Del Castillo when they were recently consulted by researchers in Israel for their expertise on specialized cells called Microfold cells, or M cells, which are mostly known for their presence in the intestinal epithelium. The Israeli group had identified similar cells in the thymus, an organ located just above the heart that makes lymphocytes — white blood cells that play an important role in the immune system and protect the body against infection. Lo, a distinguished professor of biomedical sciences in the UC Riverside School of Medicine, and Del Castillo, ...

MIT researchers have demonstrated the first system for ultra-low-power underwater networking and communication, which can transmit signals across kilometer-scale distances. This technique, which the researchers began developing several years ago, uses about one-millionth the power that existing underwater communication methods use. By expanding their battery-free system’s communication range, the researchers have made the technology more feasible for applications such as aquaculture, coastal hurricane prediction, and climate change modeling. “What started as a very exciting ...

September 6, 2023 — Among African American and other Black cisgender women, a beauty salon–based intervention improved knowledge and awareness of pre-exposure prophylaxis (PrEP) against HIV and increased trust in it, according to a pilot study published in the September issue of The Journal of the Association of Nurses in AIDS Care (JANAC), the official journal of the Association of Nurses in AIDS Care. JANAC is published in the Lippincott portfolio by Wolters Kluwer.  However, most study participants did not self-identify as requiring PrEP or having risk factors for HIV. "Like ...

Pumping liquids may seem like a solved problem but optimizing the process is still an area of active research. Any pumping application—from industrial scales to heating systems at home—would benefit from a reduction in energy demands. Researchers at the Institute of Science and Technology Austria (ISTA) now showed how pulsed pumping can reduce both friction from and energy consumption of pumping. For this, they took inspiration from a pumping system intimately familiar to everyone: the human heart. According to an international study, nearly twenty percent of global electric power are used for pumping liquids around—ranging from industrial applications ...

Birds descended from theropod dinosaurs by the Late Jurassic, but our understanding of the earliest evolution of the Avialae, the clade comprising all modern birds but not Deinonychus or Troodon, has been hampered by a limited diversity of fossils from the Jurassic. As of now, no definitive avialans have been reported except from the Middle–Late Jurassic Yanliao Biota in northeast China (166–159 million years ago; Ma) and the slightly younger German Solnhofen Limestones, which preserve Archaeopteryx. Consequently, there is a gap of about 30 million years before the oldest ...

Although about half of people go through menopause, less than 15% of them receive effective treatment for their symptoms. Treatment options for people experiencing irritating or severe menopause symptoms are often under researched, and some have questionable efficacy, or cause harmful side effects. In a comprehensive review publishing in the journal Cell on September 6, a team of world-renowned menopause experts summarizes what we know about menopause, calls for more research into the timeline and treatment of menopause, ...

Ottawa, ON, September 5, 2023 – Annual rates of emergency department visits for cannabis-involved traffic injury increased by 475 percent over 13 years, according to a new study from The Ottawa Hospital, Bruyère Research Institute, and ICES. The study examined cannabis-involvement in emergency department (ED) visits for traffic injuries between 2010 and 2021 and looked for changes after the legalization of cannabis in October 2018 and following the commercialization of the legal market (expanded cannabis products and retail stores), which overlapped with the ...

Neuroscience is in great upheaval. The two major families of cells that make up the brain, neurons and glial cells, secretly hid a hybrid cell, halfway between these two categories. For as long as Neuroscience has existed, it has been recognized that the brain works primarily thanks to the neurons and their ability to rapidly elaborate and transmit information through their networks. To support them in this task, glial cells perform a series of structural, energetic and immune functions, as well as stabilize physiological constants. Some of these glial cells, known as astrocytes, ...

By improving hospital care pathways, researchers from The University of Texas MD Anderson Cancer Center successfully reduced inpatient opioid use by 50% after pancreatic cancer surgery and cut the median opioid prescription volumes at discharge to zero. This approach, described in a study published today in JAMA Surgery, could help reduce the risk of long-term opioid dependence in patients. In this cohort study, which involved 832 patients undergoing pancreatic resection surgery, the researchers investigated how making incremental modifications to post-surgery procedures affected the amounts of opioids used by inpatients and at the point of discharge. In less ...

Analysis led by Brigham researchers showed an increase in out-of-state abortion travelers to Massachusetts from other states including Texas, Louisiana, Florida, and Georgia after Dobbs. Use of non-profit funding by charitable organizations for abortion care more than doubled among out-of-state travelers A rigorous analysis by researchers confirms a rise in out-of-state travelers coming to Massachusetts to seek abortion care. In a new study by investigators from Brigham and Women’s Hospital, a founding member ...

About The Study: Researchers identified decreases of in situ and invasive melanoma diagnoses during 2020, which may reflect decreased skin cancer screening examinations or access to dermatologic care during the pandemic, both of which may lead to reduced melanoma diagnoses. This study adds to the current literature by highlighting that the relative increase in thick melanomas in 2020 was primarily associated with a marked decrease in thin melanomas, rather than an absolute increase in thicker melanomas. Authors: Rebecca I. Hartman, M.D., M.P.H., of Brigham and Women’s Hospital in Boston, is the corresponding author. To access the embargoed study: Visit ...

About The Study: This study found large increases in cannabis involvement in emergency department visits for traffic injury over time in Ontario, Canada, which may have accelerated following nonmedical cannabis commercialization. Although the frequency of visits was rare, they may reflect broader changes in cannabis-impaired driving. Greater prevention efforts, including targeted education and policy measures, in regions with legal cannabis are indicated.  Authors: Daniel T. Myran, M.D., M.P.H., of the University of Ottawa in Ottawa, Ontario, Canada, is the corresponding author.  To access the embargoed study: Visit our For The Media website at this link https://media.jamanetwork.com/  (doi:10.1001/jamanetworkopen.2023.31551) Editor’s ...
