Comparing transmission of COVID-19 in nightlife, household, health care settings

JAMA Network Open

2023-02-24

(Press-News.org) About The Study: In this case series study that analyzed 44,000 confirmed COVID-19 cases in Tokyo, cases identified in nightlife settings were associated with a higher likelihood of spreading COVID-19 than household and health care cases. Surveillance and interventions targeting nightlife settings should be prioritized to disrupt COVID-19 transmission, especially in the early stage of an epidemic.

Authors: Michihiko Yoshida, Ph.D., of the Minato Public Health Center in Tokyo, is the corresponding author.

Association of long-term exposure to particulate air pollution with cardiovascular events

2023-02-24

About The Study: In this study including 3.7 million adults in California, long-term fine particulate air pollution (PM2.5) exposure at moderate concentrations was associated with increased risks of heart attack, ischemic heart disease mortality and cardiovascular disease mortality. The findings add to the evidence that the current regulatory standard is not sufficiently protective. Authors: Stacey E. Alexeeff, Ph.D., of the Kaiser Permanente Division of Research in Oakland, California, is the corresponding author. To access ...

Common pregnancy complications may slow development of infant in the womb, study finds

2023-02-24

Gestational diabetes and preeclampsia may be linked to slower biological development in infants, according to a new study led by USC. The research, published today in JAMA Network Open, found that newborns exposed to these two pregnancy complications were biologically younger than their chronologic gestational age. The infants’ biological or “epigenetic” age is based on molecular markers in their cells. The results raise intriguing questions about how common pregnancy complications may affect infants and health outcomes later in childhood. Could they create developmental delays? Could some exposures advance biological ...

Developing countries pay the highest price for living with large carnivores

2023-02-24

A team of researchers has highlighted human-wildlife conflict as one of the globe’s most pressing human development and conservation dilemmas. New research published in Communications Biology looked at 133 countries where 18 large carnivores ranged, and found that a person farming with cattle in developing countries such as Kenya, Uganda or India were up to eight times more economically vulnerable than those living in developed economies such as Sweden, Norway or the U.S. Duan Biggs from Northern Arizona University’s School of Earth and Sustainability is the senior author of the study. He partnered with organizations throughout the world to conduct ...

Head injuries could be a risk factor for developing brain cancer

2023-02-24

Researchers from the UCL Cancer Institute have provided important molecular understanding of how injury may contribute to the development of a relatively rare but often aggressive form of brain tumour called a glioma. Previous studies have suggested a possible link between head injury and increased rates of brain tumours, but the evidence is inconclusive. The UCL team have now identified a possible mechanism to explain this link, implicating genetic mutations acting in concert with brain tissue inflammation to change the behaviour of cells, making them more likely to become cancerous. Although this study was largely carried out in mice, it suggests ...

New study reveals biodiversity loss drove ecological collapse after the “Great Dying”

2023-02-24

SAN FRANCISCO, CA (February 24, 2023) — The history of life on Earth has been punctuated by several mass extinctions, the greatest of these being the Permian-Triassic extinction event, also known as the “Great Dying”, which occurred 252 million years ago. While scientists generally agree on its causes, exactly how this mass extinction unfolded—and the ecological collapse that followed—remains a mystery. In a study published today in Current Biology, researchers analyzed marine ecosystems before, during, and after the Great Dying ...

Differences in animal biology can affect cancer drug development

2023-02-24

A small but significant metabolic difference between human and mouse lung tumor cells, has been discovered by Weill Cornell Medicine researchers, explaining a discrepancy in previous study results, and pointing toward new strategies for developing cancer treatments. The work, published Jan. 30 in Cancer Discovery, focuses on lung adenocarcinoma, a common but often difficult to treat cancer that researchers have long studied in mouse models. However, those models didn’t quite align with human clinical observations in some instances. The new paper shows why; a specific gene mutation has opposite effects on tumor ...

Manchester research captures and separates important toxic air pollutant

2023-02-24

Led by scientists at The University of Manchester, a series of new stable, porous materials that capture and separate benzene have been developed. Benzene is a volatile organic compound (VOC) and is an important feedstock for the production of many fine chemicals, including cyclohexane. But, it also poses a serious health threat to humans when it escapes into the air and is thus regarded as an important air pollutant. The research published today in journal Chem, demonstrates the high adsorption of benzene at low pressures and concentrations, as well as the efficient separation of benzene and cyclohexane. This was achieved by the design and successful preparation ...

Using the power of artificial intelligence, new open-source tool simplifies animal behavior analysis

2023-02-24

Graphic A team from the University of Michigan has developed a new software tool to help researchers across the life sciences more efficiently analyze animal behaviors. The open-source software, LabGym, capitalizes on artificial intelligence to identify, categorize and count defined behaviors across various animal model systems. Scientists need to measure animal behaviors for a variety of reasons, from understanding all the ways a particular drug may affect an organism to mapping how circuits in the brain communicate to produce a particular behavior. Researchers ...

WHO and ESCEO announce collaborative agreement to benefit global osteoporosis and fracture prevention

2023-02-24

The World Health Organization (WHO) and the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) signed an agreement to develop a strategic roadmap on bone health and ageing and advocate for a public health strategy to prevent fractures among older people. The collaboration entails a strategic roadmap of research and publication deliverables, in recognition of the fact that osteoporosis is a major contributor to the Global Burden of Disease. The collaboration agreement, signed on February 23, 2023, at WHO Headquarters in Geneva, Switzerland, is an important ...

Discovery suggests new way to prevent common causes of vision loss

2023-02-24

UVA Health scientists have discovered an unknown contributor to harmful blood vessel growth in the eye that could lead to new treatments for blinding macular degeneration and other common causes of vision loss. UVA’s Jayakrishna Ambati, MD, and Shao-bin Wang, PhD, and their colleagues have identified a new target to prevent the formation of abnormal tangles of blood vessels associated with eye conditions such as neovascular age-related macular degeneration, proliferative diabetic retinopathy and ischemic retinal vein occlusion. “Our study has opened up the possibility of mitigating ...
