Sleep deprivation may exacerbate frailty's effects on mental health in older adults
2021-02-03
(Press-News.org) Previous studies have linked sleep deprivation and frailty with depression. A new study published in the Journal of the American Geriatrics Society that examined their combined effect suggests that short sleep intensifies the impacts of frailty on depressive symptoms.
Among 5,026 community-dwelling older adults in China, participants who were frail at the start of the study were more likely to later develop depressive symptoms. Also, those who experienced worsening frailty throughout the study tended to develop higher levels of depression. Short sleep exacerbated these effects.
The findings suggest that interventions that target sleep disturbances--such as exercise and mindfulness-based stress reduction--might help alleviate the negative effects of frailty on psychological well-being.
"We hope our research findings raise people's awareness of the combined effect of frailty and sleep on older adults' mental health, and provide implications for interventions to improve sleep quality for prefrail and frail older adults," said co-author Xinyi Zhao, PhD, of Peking University, in Beijing.

A new study published in Arthritis Care & Research has identified 10 readily available clinical factors that may predict which patients will persistently use high doses of opioids in the year following knee replacement surgery.
In the study of 142,089 Medicare patients with osteoarthritis who underwent total knee replacement surgery and had no history of high-dose opioid use, 10.6% became persistent users of high-dose opioids after surgery.
Certain preoperative characteristics including demographics (age, sex, and race), history of substance abuse (opioids, alcohol, and tobacco), and medication use (benzodiazepines, anxiolytics, antidepressants, anticonvulsants, and nonsteroidal anti-inflammatory drugs) were predictors of persistent use of high-dose opioids after surgery. ...

Investigators have published a global review of mammal strikes with aircraft, noting that events have been increasing by up to 68% annually. More mammals were struck during the landing phase of an aircraft's rotation than any other phase, according to the article published in Mammal Review.
By analyzing published information and mammal strike data from national aviation authorities in Australia, Canada, France, Germany, the United Kingdom, and the United States, researchers found that bats accounted for the greatest proportion of strikes in Australia; rabbits and dog-like carnivores in Canada, Germany, and the United Kingdom; and bats and deer in the United States. Average mammal strikes per year ranged from 1.2 to 38.7 across the countries ...

CLEVELAND, Ohio (Feb 3, 2021)--Postmenopausal women often complain of painful intercourse or a lack of desire caused by decreased estrogen levels, which affect vaginal elasticity and lubrication. Survivors of breast cancer typically experience worse symptoms as a result of cancer treatments, and concerns exist regarding hormone therapies. A new study suggests that fractional CO2 laser therapy may help. Study results are published online in Menopause, the journal of The North American Menopause Society (NAMS).
The menopause transition can subject women to genitourinary changes from a lack of estrogen and subsequent ...

BINGHAMTON, NY -- Most zoombombing incidents are "inside jobs" according to a new study featuring researchers at Binghamton University, State University of New York.
As the COVID-19 virus spread worldwide in early 2020, much of our lives went virtual, including meetings, classes and social gatherings.
The videoconferencing app Zoom became an online home for many of these activities, but the migration also led to incidents of "zoombombing" -- disruptors joining online meetings to share racist or obscene content and cause chaos. Similar apps such as Google Meet and Skype also saw problems.
Cybersecurity experts expressed concerns ...

Dogs have been faithful human companions ever since their domestication thousands of years ago. With various improvements in veterinary medicine in the past decades, their life expectancy has increased. However, an unfortunate side effect of this longevity, much like in humans, has been an increase in the occurrence of chronic and degenerative conditions.
In humans, modern efforts to fight such diseases have culminated in the development of regenerative therapies, largely based on stem cells. These "baby" cells have the potential to differentiate and mature into many specialized cell types-- called "pluripotency." By transplanting stem cells and guiding their differentiation into desired cell ...

There are more than 350,000 angiosperms which are key components of ecosystems. It is now commonly accepted that their existence is essential for preserving a healthy environment and also for the production of food and raw materials. The growing world population and the challenges posed by climate change make the control of these natural resources one of the most crucial issues for all humanity in the future. In this regard, genome sequence information is of fundamental importance for understanding natural diversity and evolution of living organisms as well as for the design of breeding strategies aimed to produce new varieties with suitable traits.
Although the first genome sequence of the model plant Arabidopsis thaliana was produced more than twenty years ago, the sequencing ...

When most people hear "food contamination," they think of bacteria present on unwashed fruits or vegetables, or undercooked meat. However, there are other ways for harmful contaminants to be present in food products.
Angelia Seyfferth, a member of the Soil Science Society of America, investigates food contamination coming from the soil where the plants grow. "It all comes down to the chemistry of the soil," explains Seyfferth.
Most recently, Seyfferth has been studying rice. The elements arsenic and cadmium can be present in the paddies where rice is grown. She presented her research at the virtual 2020 ASA-CSSA-SSSA Annual Meeting.

Study using surveys of more than 1.1 million 13-15-year-olds from 140 countries between 1999 and 2018, finds that the prevalence of smoking cigarettes on at least one day during the past 30 days decreased in 80 countries (57%) but was unchanged or increased in 60 countries (43%).
However, during the same time period, the prevalence of using other tobacco products, such as chewing tobacco, snuff, dip, cigars, cigarillos, pipe, or electronic cigarettes, levelled off or increased in 81 (59%) of 137 countries with available data.
Surveys of more than 530,000 adolescents from 143 countries between 2010 and 2018, finds that 17.9% of boys and 11.5% of girls used any tobacco product on at least one day during the past month.

RIVERSIDE, Calif. -- A team led by a biomedical scientist at the University of California, Riverside, reports a drug -- an estrogen receptor ligand called indazole chloride (IndCl) -- has the potential to improve vision in patients with multiple sclerosis, or MS.
The study, performed on mice induced with a model of MS and the first to investigate IndCl's effect on the pathology and function of the complete afferent visual pathway, is published in Brain Pathology. The afferent visual pathway includes the eyes, optic nerve, and all brain structures responsible for receiving, transmitting, and processing visual information.
In MS, a disease ...

Northwestern University researchers have developed a new approach to quantum device design that has produced the first gain-based long-wavelength infrared (LWIR) photodetector using band structure engineering based on a type-II superlattice material.
This new design, which demonstrated enhanced LWIR photodetection during testing, could lead to new levels of sensitivity for next-generation LWIR photodetectors and focal plane array imagers. The work could have applications in earth science and astronomy, remote sensing, night vision, optical communication, and thermal and medical imaging.
"Our design ...
