Smartwatch measures of outdoor exposure and nearsightedness in children

JAMA Network Open

2024-08-13

(Press-News.org) About The Study: In this 1-year prospective cohort study of children with smartwatches, continuous outdoor exposure with at least 15 minutes accompanied with no less than 2,000 lux sunlight intensity was associated with less myopic shift. These findings suggest that future outdoor interventions should focus not only on the overall time outdoors but also on the effective outdoor exposure patterns, as a means to effectively prevent myopia (nearsightedness) in children.

Lurie Children’s Hospital awarded $12 million by PCORI to study best approach to treat mild pneumonia in young children

2024-08-13

Ann & Robert H. Lurie Children’s Hospital of Chicago, in partnership with University of Utah Health, has been approved for $12 million in research funding by the Patient-Centered Outcomes Research Institute (PCORI) for a study that will compare two ways to use antibiotics in young children with mild pneumonia, one of the leading reasons children seek acute care, who are well enough to be cared for at home. The first approach is to prescribe and give antibiotics immediately, which is the current standard of care. The second way is to prescribe an antibiotic but not give it unless the child’s symptoms worsen or ...

Study finds emergency department visits by children associated with water beads more than doubled from 2021 to 2022

2024-08-13

(COLUMBUS, Ohio) – Researchers from the Center for Injury Research and Policy and Central Ohio Poison Center at Nationwide Children’s Hospital have found more than an estimated 8,000 visits to U.S. emergency departments (EDs) associated with water beads from 2007 through 2022, and the number of these visits increased rapidly by more than 130% from 2021 to 2022. In a study published in American Journal of Emergency Medicine, researchers analyzed 16 years of data and call for a more comprehensive regulatory approach to prevent water bead-associated injuries. The increase in ...

A Macquarie University team proposes using genetically engineered black soldier flies (Hermetia illucens) to address worldwide pollution challenges and produce valuable raw materials for industry, including the USD $500 billion global animal feed market. In a new paper published on 24 July in the journal Communications Biology, scientists at Macquarie University outline a future where engineered flies could transform waste management and sustainable biomanufacturing, addressing multiple United Nations Sustainable Development Goals (SDGs). Synthetic biologist Dr Kate Tepper is lead author of the paper and a Postdoctoral Research Fellow at Applied BioSciences, Macquarie University. “One ...

Lung nodules seen in a high percentage of non-smokers

2024-08-13

OAK BROOK, Ill. – A new study of more than 10,000 non-smoking adults found that solid lung nodules were present in a considerable portion of study participants. Non-smokers are traditionally thought to be at low risk for lung nodules and lung cancer. The results of the study were published today in Radiology, a journal of the Radiological Society of North America (RSNA). Incidental lung nodules are common findings on chest CT and in high-risk groups are more likely to be a sign of early-stage lung cancer. Because most previous research on the prevalence and size of lung nodules has typically been ...

Study shows text messages help youth at risk for suicide feel supported after discharge

2024-08-13

(COLUMBUS, Ohio) – As the nation’s youth mental health crisis continues, providers continue to find ways to help address gaps in care. Patients who receive care for suicidal thoughts and behaviors need extra support as they transition after they are discharged from inpatient care or the emergency department. Caring Contacts are validating messages sent to patients via text messages, postcards or letters to offer patients ongoing care and support without placing any demands (such as reminders to attend their next appointment). At Nationwide ...

Protecting surf breaks mitigates climate change, helps coastal communities, analysis finds

2024-08-13

CORVALLIS, Ore. – Safeguarding places to hang ten and shoot the curl is an opportunity to simultaneously mitigate climate change, fuel tourism and help surrounding ecosystems, new research has shown. “There is a growing conservation movement regarding coastal areas that host surf breaks,” said Jacob Bukoski of Oregon State University, one of the study’s co-authors. “Earlier research showed that surf breaks tend to be biodiversity hotspots, but no one had looked at the stocks of carbon held within these ecosystems – carbon that could drive climate change if ...

New species of extinct walrus-like mammal discovered in the North Atlantic

2024-08-13

A new discovery by a team of paleontologists, led by Dr. Mathieu Boisville (University of Tsukuba, Japan), has uncovered a new species of the extinct genus Ontocetus from the Lower Pleistocene deposits in the North Atlantic. This species, named Ontocetus posti, displays surprising similarities in feeding adaptations to the modern walrus (Odobenus rosmarus), highlighting an intriguing case of convergent evolution. The research is published in the open access journal PeerJ Life & Environment. The fossils ...

Empowering women – a key to both sustainable energy and gender justice

2024-08-13

Involving women in implementing solar energy technologies in developing countries not only has great climate impact. A new study published in Nature Energy and carried out by researchers from Chalmers University of Technology, Sweden, shows that empowering women through energy care work can change unjust, gendered norms and long-lived injustices. Unlike going from fossil to renewable fuels within the transport sector, transitioning to renewable energy for electricity production is often done at the local level due to decentralised energy providers. Around the world, there are community-led programmes that provide solar, wind and hydro power, as alternative, greener energy sources. ...
