New reptile on the block: A new iguana species discovered in China

New reptile on the block: A new iguana species discovered in China
2023-12-27
(Press-News.org) A new iguana joins Asia’s rich reptile fauna, officially described as new to science in the open-access journal ZooKeys.

“From 2009 to 2022, we conducted a series of field surveys in South China and collected a number of specimens of the Calotes versicolor species complex, and found that the population of what we thought was Calotes versicolor in South China and Northern Vietnam was a new undescribed species and two subspecies,” says Yong Huang, whose team described the new species.

Wang’s garden lizard (Calotes wangi) is less than 9 cm long, and one of its distinguishing features is its orange tongue.

“Calotes wangi is found in subtropical evergreen broad-leaved forests and tropical monsoon forests in southern China and northern Vietnam, mostly in mountainous areas, hills and plains on forest edges, arable land, shrub lands, and even urban green belts. It is active at the edge of the forest, and when it is in danger, it rushes into bushes or climbs tree trunks to hide. Investigations found that the lizards lie on sloping shrub branches at night, sleeping close to the branches,” says Yong Huang.

It is active from April to October every year, while in the tropics it is active from March to November or even longer, and eats a variety of insects, spiders, and other arthropods.

For now, the researchers estimate that the new species is not threatened, but they do note that in some areas its habitat is fragmented.

“In addition, their bodies are used medicinally and the lizards are also eaten,” they write in their research paper.

This is why they suggest that the local government strengthen the protection of their ecological environment and pay close attention to the population dynamics.

Quality of care declines after private equity takes over hospitals

2023-12-26
At a glance: National study of quality of care in hospitals acquired by private equity shows worsening of fall and infection risk, other measures of quality and safety. Some post-procedure adverse events increased even though private equity hospitals performed fewer procedures among younger and less disadvantaged patients. The new findings amplify existing economic concerns about the growth of this for-profit ownership model. Patients are more likely to fall, get new infections, or experience other forms of harm during their stay in a hospital after it is acquired by a private equity firm, according to a new ...

Changes in hospital adverse events and patient outcomes associated with private equity acquisition

2023-12-26
About The Study: Private equity acquisition of hospitals, on average, was associated with increased hospital-acquired adverse events despite a likely lower-risk pool of admitted Medicare beneficiaries, suggesting poorer quality of inpatient care. These findings heighten concerns about the implications of private equity on health care delivery.  Authors: Zirui Song, M.D., Ph.D., of Harvard Medical School in Boston, is the corresponding author.

Variation by institution in sexual harassment experiences among medical interns

2023-12-26
About The Study: Among a national cohort of medical interns, over half experienced sexual harassment. Although harassment was prevalent across programs, institutional and specialty training variations in interns’ sexual harassment experiences exist, thereby providing additional evidence that residency programs and institutions play an important role in combating this widespread problem.  Authors: Elizabeth M. Viglianti, M.D., M.P.H., M.Sc., of the University of Michigan in Ann Arbor, is the corresponding author.  To ...

Negative wealth shock and cognitive decline and dementia in middle-aged and older adults

2023-12-26
About The Study: In this study of 8,000 participants, negative wealth shock (a loss of 75% or more in total wealth over a 2-year period) was associated with accelerated cognitive decline and elevated risks of dementia among middle-aged and older U.S. adults, with modifications by age and ethnicity. These findings should be confirmed by further prospective and interventional studies.  Authors: Jing Guo, Ph.D., of the Zhejiang University School of Medicine in Hangzhou, China, is the corresponding author.  To access ...

Prediction of 2-year cognitive outcomes in very preterm infants using machine learning methods

2023-12-26
About The Study: The findings of this prognostic study of cognitive outcomes at 2-year follow-up among 1,000 infants born very preterm suggest that predictive modeling in neonatal care could enable early and targeted intervention for very preterm infants most at risk for developing cognitive impairment.  Authors: Andrea K. Bowe, M.B., M.P.H., of University College Cork in Cork, Ireland, 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.2023.49111) Editor’s Note: Please see the article for additional information, including other authors, ...

Pet ownership, living alone, and cognitive decline among adults age 50 and older

2023-12-26
About The Study: Pet ownership was associated with slower rates of decline in verbal memory and verbal fluency among older adults living alone, but not among those living with others in this study of 7,900 participants age 50 and older. Pet ownership offset the associations between living alone and declining rates in verbal memory and verbal fluency. Further studies are needed to assess whether pet ownership slows the rate of cognitive decline in older adults living alone.  Authors: Ciyong Lu, Ph.D., of Sun Yat-sen University in Guangzhou, China, is the corresponding author.  To ...

Scientists use organoid model to identify potential new pancreatic cancer treatment

Scientists use organoid model to identify potential new pancreatic cancer treatment
2023-12-26
A drug screening system that models cancers using lab-grown tissues called organoids has helped uncover a promising target for future pancreatic cancer treatments, according to a new study from researchers at Weill Cornell Medicine. In the study, published Dec. 26 in Cell Stem Cell, the scientists tested more than 6,000 compounds on their pancreatic tumor organoids, which contain a common pancreatic cancer-driving mutation. They identified one compound—an existing heart drug called perhexiline maleate—that powerfully suppresses ...

Risk of young-onset dementia could be reduced through targeting health and lifestyle factors - study

2023-12-26
December 21 Peer reviewed /observational study / in people* Strictly embargoed 4PM UK time on Tuesday December 26 Researchers have identified a wide range of risk factors for young-onset dementia. The findings challenge the notion that genetics are the sole cause of the condition, laying the groundwork for new prevention strategies. The largescale study identified 15 risk factors, which are similar to those for late-onset dementia. For the first time, they indicate that it may be possible to reduce the risk of young-onset dementia ...

Artificial intelligence predicts the influence of microplastics on soil properties

Artificial intelligence predicts the influence of microplastics on soil properties
2023-12-26
Plastic waste and its buildup in nature has become a major environmental concern in recent times. While plastic pollution in the oceans is undoubtedly a concern, the presence of plastics in soils around the world is also known to cause severe environmental and health issues. As plastics fragment into smaller pieces known as microplastics (MPs) in the soil through natural and anthropogenic processes, they drastically alter soil properties. Moreover, they are also absorbed by plants, potentially entering human ...
