Heated tobacco products—an alternative to traditional cigarettes, similar to e-cigarettes or vapes—do not burn tobacco leaves, but rather allow users to inhale the vapor produced by heating the tobacco leaves. Users choose heated tobacco products to avoid the smoke and odor of burnt tobacco as well as the expectation that they pose fewer health risks than traditional cigarettes. However, the long-term health effects of heated tobacco products, particularly the new risk of SARS-CoV-2 infection, have not been clarified.
Addressing this concern, a research group led by Associate Professor Kazuhisa Asai from the Osaka Metropolitan University Graduate School of Medicine conducted a study focusing on the relationship between using heated tobacco products and SARS-CoV-2 infection.
The research group investigated the relationship between tobacco use, including heated tobacco products and traditional cigarettes with SARS-CoV-2 infection and possible exacerbations of COVID-19. They administered an online survey of living conditions in February 2022 to 30,130 participants aged 16-81 years, who were randomly selected from the general population through an online survey according to a representative distribution, and conducted further statistical analyses.
From their analysis, the research group found that users of heated tobacco products–including both people who use them exclusively or in combination with traditional cigarettes—had significantly higher rates of COVID-19 compared to non-users. Furthermore, among all tobacco users, those who used both heated tobacco products and traditional cigarettes had the incidence of severe illness—requiring hospitalization or oxygen due to COVID-19.
“This study shows that the use of heated tobacco products may have an impact on SARS-CoV-2 infections and disease progression. We hope this report will encourage people to think about tobacco use in the context of the added risks due to coronavirus infection,” Professor Asai concluded.
The findings were published in Scientific Reports on February 2, 2023.

Corneal transplants can be the last step to returning clear vision to many patients suffering from eye disease. Each year, approximately 80,000 corneal transplantations take place in the U.S. Worldwide, more than 184,000 corneal transplantation surgeries are performed annually.
However, rejection rates for the corneal grafts can be as high as 10%. This is largely due to poor patient compliance to the medications, which require frequent administrations of topical eyedrops over a long period of time.
This becomes especially acute when patients ...

The diet quality of fish across large parts of the world’s oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.
QUT School of Mathematical Sciences researcher Dr Ryan Heneghan led the study published in Nature Climate Change that included researchers from the University of Queensland, University of Tasmania, University of NSW and CSIRO.
They modelled the impact of climate change on zooplankton, an abundant and extremely diverse group of microscopic animals accounting for about 40 per cent ...

URBANA, Ill. – The U.S. dairy industry operates a comprehensive data collection program that records herd production information from farmers nationwide. The program provides crucial input for cattle breeding and genetics, and its cooperative structure ensures benefits for producers and scientists alike. A new study from the University of Illinois explores the program’s century-old history, highlighting its relevance for modern agriculture and digital data collection.
“The National Cooperative Dairy Herd Improvement Program (NCDHIP) is an interesting case study because it illustrates how to translate the benefits ...

UNIVERSITY PARK, Pa. — U.S. college students’ knowledge of bees focuses primarily on honey bees and pollination services, according to Penn State researchers, who said findings from their recent study could help in designing campaigns to generate support for protecting threatened pollinators.
Wild and managed bee populations have been in steep decline worldwide in recent years, noted study co-author Christina Grozinger, Publius Vergilius Maro Professor of Entomology and director of the Center for Pollinator Research in ...

VANCOUVER -- Deep brain stimulation (DBS) has become an increasingly common treatment for patients with advanced Parkinson’s disease, but the procedure still carries significant risks. A new probe that performs two types of spectroscopy could make the procedure safer and improve success rates by helping doctors more accurately navigate instruments inside the brain. The research team identified white and grey matter using principal component analysis (PCA), proving that spectroscopic measurements could be suitable for neuronavigation.
For DBS, surgeons place electrodes in the brain to disrupt the errant signals that cause debilitating tremors and stiffness associated ...

UNIVERSITY PARK, Pa. — The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web — ground beetles. Nearly 2,000 species of ground beetle live in North America. New research led by Penn State shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species’ traits and habitats and could have significant implications for conservation efforts.
“We know that climate change influences everything from coral reefs in the ocean to trees on land, but there’s ...

Researchers at the Johns Hopkins Bloomberg School of Public Health contributed to a new Centers for Disease Control and Prevention report that found a continued rise in the overall prevalence of autism among 8-year-olds in 2020, the year the data was collected, as well as notable sex and racial/ethnic trends. In Maryland, the autism rate among 8-year-olds also rose, but it was the lowest prevalence among 11 sites that contributed to the study.
Autism spectrum disorder (ASD) is a developmental disorder that can be characterized by social and communication challenges, along with limited interests and repetitive behaviors.
The prevalence of ASD has risen steadily ...

A recent U.S. federal court ruling that removes a requirement for employers to provide insurance coverage for the HIV prevention medications known as Pre-Exposure Prophylaxis, or PrEP, could result in more than 2,000 entirely preventable HIV infections in the coming year, according to a new study led by researchers at the Yale School of Public Health.
The study addresses the potential consequences of a September 2022 decision by U.S. District Judge Reed O’Connor of Texas in a case known as Braidwood Management v. Becerra. O’Connor ruled in favor of the plaintiffs, a group of Christian business owners who claimed that federal mandates requiring private insurance ...

The University of Southern California (USC) is collaborating with Auransa Inc., on a phase 1 clinical trial to evaluate a new kind of treatment for cancers of the liver and solid tumors with liver dominant disease. The drug, known as AU409, was developed by Auransa, a clinical stage drug development company focused on identifying novel drug candidates for oncology, inflammatory diseases and diseases of the central nervous system. In preclinical trials, AU409, has been shown to work in a unique fashion by limiting the cancer cell’s ability to translate the message from various genes ...
