SPOKANE, Wash. - Many people likely lost sleep over COVID-19. A study of twins led by Washington State University researchers found that stress, anxiety and depression during the first few weeks of the pandemic were associated with less and lower quality sleep. In a survey of more than 900 twins taken shortly after COVID-19 lockdown measures began, about half of the respondents reported no change in their sleep patterns, but around a third, 32.9%, reported decreased sleep. Another 29.8% reported sleeping more. In the analysis, the researchers found that any change in sleep was connected to self-reported mental health issues, though it was more strongly associated with decreased ...

Ireland, June 17 2021: Popular video games have the potential to provide low-cost, easy access, effective and stigma-free support for some mental health issues, researchers at Lero, the Science Foundation Ireland Research Centre for Software, have found. The team at Lero, a world leader in connected-health research, said video games could be used where conventional therapies are not available because of cost or location, or as an addition to traditional therapeutic treatments for depression or anxiety. Lero researcher Dr Mark Campbell said there is mounting scientific ...

Researchers have designed a device that delivers two medications that help stop HIV transmission. Although condom usage is the best strategy for preventing HIV transmission, the researchers are working to design a device that can be used by sex workers and in situations where women are not in a position to negotiate condom use. The device is an intravaginal ring (IVR ) that can be inserted into the female genital tract where it will deliver medications known to decrease the transmission of HIV. The researchers examined how effectively their IVR delivered two medications - hydroxychloroquine (HCQ), an FDA approved medication, and a nanomedicine gene therapy developed by the team in previous research. Their results were published in a ...

New research published in BMJ Open shows that community pharmacy could play a 'key clinical role' in the future role of COVID-19 vaccination programmes, according to a study led by Aston University in Birmingham, UK, in collaboration with UK and international researchers. The team found that community pharmacists, as a 'skilled clinical workforce', could positively contribute, supporting the community in which they serve - by playing a critical role in ongoing COVID-19 vaccination campaigns. The researchers working on the PERISCOPE study found that community pharmacy is uniquely placed to support individuals, because it is seen by the public as a credible, trustworthy service, which could be key to any future clinical ...

The role of people infected with malaria without showing symptoms presents a hidden risk to efforts to control the disease after they were found to be responsible for most infections in mosquitoes, according to a study published in The Lancet Infectious Diseases. Researchers from the Infectious Diseases Research Collaboration (IDRC), London School of Hygiene & Tropical Medicine (LSHTM), Radboud university medical center and University of California, San Francisco, found asymptomatic children in the Uganda study were the biggest source of malaria parasites transmitted to mosquitoes. This could provide a new opportunity for control efforts by targeting this infectious reservoir. ...

Corticosteroids may be an effective treatment for children who develop a rare but serious condition after COVID-19 infection. This is the finding of an international study of 614 children, published in the New England Journal of Medicine, led by Imperial College London. All children in the study developed a serious disorder following COVID-19 infection. This condition, called multi-system inflammatory syndrome in children (MIS-C), is thought to affect 1 in 50,000 children with SARS-CoV-2 infection. The new disorder, which is also called paediatric inflammatory multi-system syndrome temporally associated with SARS-CoV-2 infection (PIMS-TS), affects children of all ages but is more common in older children ...

During the first several months of the pandemic -- when communities locked down, jobs were lost, PPE was scarce and store shelves were cleared --thousands of people turned to online crowdfunding to meet their needs. But a new University of Washington analysis of requests and donations to the popular crowdfunding site GoFundMe, along with Census data, shows stark inequities in where the money went and how much was donated. A study published June 15 in Social Science & Medicine found more than 175,000 COVID-19-related GoFundMe campaigns in the U.S., raising more than $416 million, from January through July 2020. Researchers found that affluent and educated ...

'God forbid we need this, but we'll be ready' Medication would be taken early in the disease, so you don't get as sick Future drug could also treat common cold CHICAGO --- Scientists are already preparing for a possible next coronavirus pandemic to strike, keeping with the seven-year pattern since 2004. In future-looking research, Northwestern University Feinberg School of Medicine scientists have identified a novel target for a drug to treat SARS-CoV-2 that also could impact a new emerging coronavirus. "God forbid we need this, but we will be ready," said Karla Satchell, professor of microbiology-immunology at Feinberg, who leads an international team of scientists to analyze the important structures of the virus. The Northwestern team previously ...

An innovative underwater robot known as Mesobot is providing researchers with deeper insight into the vast mid-ocean region known as the "twilight zone." Capable of tracking and recording high-resolution images of slow-moving and fragile zooplankton, gelatinous animals, and particles, Mesobot greatly expands scientists' ability to observe creatures in their mesopelagic habitat with minimal disturbance. This advance in engineering will enable greater understanding of the role these creatures play in transporting carbon dioxide from the atmosphere to the deep sea, as well as how commercial exploitation of twilight ...

CORVALLIS, Ore. - Human-caused wildfire ignitions in Central Oregon are expected to remain steady over the next four decades and lightning-caused ignitions are expected to decline, but the average size of a blaze from either cause is expected to rise, Oregon State University modeling suggests. Scientists including Meg Krawchuk of the OSU College of Forestry and former OSU research associate Ana Barros, now of the Washington Department of Natural Resources, say the findings can help local decision-makers understand how a changing climate might affect natural and human-caused fire regimes differently and inform ...

Researchers at the National Eye Institute (NEI) have determined how certain short protein fragments, called peptides, can protect neuronal cells found in the light-sensing retina layer at the back of the eye. The peptides might someday be used to treat degenerative retinal diseases, such as age-related macular degeneration (AMD). The study published today in the Journal of Neurochemistry. NEI is part of the National Institutes of Health. A team led by Patricia Becerra, Ph.D., chief of the NEI Section on Protein Structure and Function, had previously derived these peptides from a protein called pigment epithelium-derived ...

A study of young immigrant mothers who are survivors of sex trafficking found that the trauma affected how they parented: it made them overprotective parents in a world perceived to be unsafe, it fueled emotional withdrawal when struggling with stress and mental health symptoms, and was a barrier to building confidence as mothers. Yet, they coped with such challenges finding meaning in the birth of their child and through social support and faith. Results of the community-based participatory research study by researchers at Columbia University ...

An alternate-day intermittent fasting schedule offered less fat-reducing benefits than a matched "traditional" diet that restricts daily energy intake, according to a new, 3-week randomized trial involving 36 participants. The study, which is one of the first to tease apart the effects of fasting and daily energy restriction in lean individuals, indicates that alternate-day fasting may offer no fasting-specific health or metabolic benefits over a standard daily diet. However, the authors caution that longer studies with larger groups are needed. Intermittent fasting, which involves cycling through voluntary fasting and non-fasting periods, has become one of the most popular approaches to losing weight. There ...

We've seen robots take to the air, dive beneath the waves and perform all sorts of maneuvers on land. Now, researchers at UC Santa Barbara and Georgia Institute of Technology are exploring a new frontier: the ground beneath our feet. Taking their cues from plants and animals that have evolved to navigate subterranean spaces, they've developed a fast, controllable soft robot that can burrow through sand. The technology not only enables new applications for fast, precise and minimally invasive movement underground, but also lays mechanical foundations for new types of robots. "The biggest challenges with moving through the ground ...

In a study of more than 10,600 adult patients hospitalized with COVID-19, women had significantly lower odds than men of in-hospital mortality. They also had fewer admissions to the intensive care unit and less need for mechanical ventilation. Women also had significantly lower odds of major adverse events, including acute cardiac injury, acute kidney injury, and venous thromboembolism, according to an article in the peer-reviewed Journal of Women's Health. Click here to read the article now. "This comprehensive analysis is the largest study to date that directly assesses the impact of sex on COVID-19 outcomes," ...

Boston - New study results indicate that different comorbid conditions affecting individuals diagnosed with COVID-19 may impact how long they continue to receive positive SARS-CoV-2 polymerase chain reaction (PCR) test results. Individuals diagnosed with COVID-19 who are aged 60+, have three or more chronic medical conditions, particularly diabetes, obesity, rheumatologic disease, or an organ transplant, have positive PCR tests for longer periods of time compared to younger individuals without these comorbidities. However, the data showed no significant difference in the duration of positive PCR tests results by the degree of immunocompromise or for individuals receiving chemotherapy or steroids ...

EAST LANSING, Mich. - The original Star Trek television series took place in a future when space is the final frontier, but humanity hasn't reached that point quite yet. As researchers like Michigan State University entomologists Sarah Smith and Anthony Cognato are reminding us, there's still plenty to discover right here on Earth. Working in Central and South America, the duo discovered more than three dozen species of ambrosia beetles -- beetles that eat ambrosia fungus -- previously unknown to science. Smith and Cognato described these new species on June 16 in the journal ZooKeys. The Spartans also selected ...

Researchers from Skoltech and their colleagues from the UK have managed to create a stable giant vortex in interacting polariton condensates, addressing a known challenge in quantized fluid dynamics. The findings open possibilities in creating uniquely structured coherent light sources and exploring many-body physics under unique extreme conditions. The paper was published in the journal Nature Communications. In fluid dynamics, a vortex is a region where a fluid revolves around a point (2D) or a line (3D); you've clearly seen one in your sink ...

Ikoma, Japan - Humans pride themselves on being able to multitask, especially under pressure. But it turns out that we aren't the only ones who are organized: researchers from Japan have discovered that plants balance genome maintenance with organ growth by organizing different responses to DNA damage. In a study published in Science Advances, a research team led by Nara Institute of Science and Technology has revealed that plants use combined control of the plant hormones cytokinin and auxin to organize DNA damage responses while maintaining growth. Plants are highly adaptable organisms that never stop growing, thanks largely to the functions carried out by their roots. Because of the essential role that roots play in plant growth, ...

A new study using cells, transgenic mouse models, and cultured human lung tissue provides evidence that the ability to trigger programmed cell death (apoptosis) may enable highly pathogenic coronaviruses to spread within their hosts so successfully. Targeting this process may reduce the severity of coronavirus diseases, the study goes on to show. While scientists have been aware that highly pathogenic coronaviruses leave substantial cell death in their wake as they infiltrate the body, the importance of apoptosis to the internal spread of coronavirus infections ...

Nanoengineers at the University of California San Diego have developed immune cell-mimicking nanoparticles that target inflammation in the lungs and deliver drugs directly where they're needed. As a proof of concept, the researchers filled the nanoparticles with the drug dexamethasone and administered them to mice with inflamed lung tissue. Inflammation was completely treated in mice given the nanoparticles, at a drug concentration where standard delivery methods did not have any efficacy. The researchers reported their findings in Science Advances on June 16. What's special ...

Parenting is one of life's greatest joys, right? Not for everyone. New research from Michigan State University psychologists examines characteristics and satisfaction of adults who don't want children. As more people acknowledge they simply don't want to have kids, Jennifer Watling Neal and Zachary Neal, both associate professors in MSU's department of psychology, are among the first to dive deeper into how these "child-free" individuals differ from others. "Most studies haven't asked the questions necessary to distinguish 'child-free' individuals -- those who choose not to have children -- from other types of nonparents," Jennifer Watling Neal said. ...

Chemokine receptors, located at the surface of many immune cells, play an important role in their function. Chemokines are small proteins that bind to these receptors and control the movement and behaviour of white blood cells. However, despite the importance of this family of receptors, their activation mechanism remains poorly understood. In Switzerland, a research consortium from the University of Geneva (UNIGE), the Biozentrum of the University of Basel, and the Paul Scherrer Institute (PSI) in Villigen has succeeded in decoding the activation mechanism of the CCR5 receptor, a member of this family implicated in several diseases such as HIV/AIDS, cancer, and the respiratory ...

New research published this week challenges a popular belief that intermittent fasting diets such as alternate day fasting or the '5:2' are the most effective ways to lose weight. Over recent years, diets which see people fast on a few days each week have increased in popularity, reinforced by images of people's miraculous weight transformations, and backed by celebrity endorsements. However, evidence to date about the effectiveness of fasting compared with more traditional diets which aim to reduce calorie intake over the course of a full week has been limited. Published in the prestigious journal Science Translational Medicine, the new study from a team of physiologists at the University of Bath builds this evidence and indicates that there is 'nothing ...

PHILADELPHIA (June 16, 2021) - The current Medicare reimbursement policy for nurse practitioners (NPs) allows NPs to directly bill Medicare for services that they perform, but they are reimbursed at only 85% of the physician rate. A growing number of states are granting full practice authority to nurse practitioners. Even more states have loosened practice restrictions due to COVID-19. Both of these reasons illustrate why payment parity is essential. In an article in The Online Journal of Issues in Nursing, Alycia Bischof, MSN, APRN, PNP-BC, Senior Lecturer at the ...
