Clues for improving sleep in visually impaired athletes

Researchers from the University of Tsukuba have identified the prevalence and risk factors associated with sleep disorders in visually impaired athletes

2021-02-16
(Press-News.org) Tsukuba, Japan - Sleep is very important for athletes, and sleep loss can affect physical performance and cognitive ability. But now, researchers from the University of Tsukuba have identified the prevalence of sleep disorders in visually impaired athletes, as well as specific risk factors associated with lower sleep quality.

In a study published last November in Sleep Medicine, researchers from the University of Tsukuba conducted a survey of 99 visually impaired athletes in Japan and analyzed data from 81 respondents. They found that approximately one-third of the respondents had sleep disorders. Further, higher levels of stress regarding interpersonal relationships in competition activities and a later wake-up time were associated with the rate of sleep disorders.

As sleep disorders are known to be especially common in visually impaired individuals, athletes who are visually impaired may be especially at risk. However, the factors associated with sleep quality in visually impaired athletes are unknown. Therefore, the researchers at the University of Tsukuba aimed to address this in their study.

To examine the prevalence and risk factors associated with sleep disorders in visually impaired athletes, the researchers collected data regarding the severity of vision loss, sleep quality, lifestyle habits, competition activities, and psychological distress in visually impaired athletes who were active in Paralympic sports events in Japan, such as marathon running, goalball, swimming, blind soccer, and judo.

"Our data indicated that roughly a third of the study participants had sleep disorders," explains Professor Takeda. "This prevalence was similar to that found in sighted athletes, including other para-athletes."

"Our analysis revealed that stress associated with interpersonal relationships in competition activities was independently related to sleep disorders in the study participants," explains Professor Takeda, "as was a late wake-up time."

Given that interpersonal stressors arising from competition activities were associated with sleep disorders, new strategies for improving these relationships could help improve sleep quality in visually impaired athletes. Further, strategies to help athletes adjust their wake-up time may have a positive effect on sleep quality.

Melanoma patients respond to immunotherapy after changes to gut microbiome

2021-02-16
CORVALLIS, Ore. - Statistical modeling developed by Oregon State University researchers has confirmed that changes to melanoma patients' gut microbiome led them to respond to a type of treatment capable of providing long-term benefit. Findings were published in Science. The modeling technique invented by Andrey Morgun of the OSU College of Pharmacy and Natalia Shulzenko of Oregon State's Carlson College of Veterinary Medicine is known as transkingdom network analysis. The human gut microbiome is a community of more than 10 trillion microbial cells from about 1,000 different bacterial species, and transkingdom network analysis integrates ...

Water is a probable vector for mammalian virus transmission

Water is a probable vector for mammalian virus transmission
2021-02-16
Water is a necessity for all life but its availability can be limited. In geographical areas experiencing dry seasons, animals congregate near the few freshwater sources, often reaching large densities. At these sites many animals from different species come to the same spots to drink, potentially operating as key locations for pathogen transmission within and between species. An international team of scientists lead by the German Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) suggests that viruses can use restricted freshwater sources as a vector to be spread among animals. The key prediction of this idea is that animal viruses remain stable and infectious in water. The team ...

Method for temporal monitoring of microplastic sedimentation

Method for temporal monitoring of microplastic sedimentation
2021-02-16
The effects of microplastics on our health and the environment are being rigorously studied all across the world. Researchers are identifying microplastic sources and their potential routes to the environment by examining rainwater, wastewater, and soil. Microplastics have been found in nearly all organisms and habitats everywhere in the world. However, factors contributing to the influx and accumulation of microplastics in water ecosystems aren't fully understood yet. The focus of microplastics research has, for a long time, been on the age of microplastics found in sediments, and on the ...

New discovery may enable accurate prediction of cancer spread before cancer develops

2021-02-16
The researchers analysed cells, mouse models, and human patient samples using biochemical, mathematical, and biophysical methods. They identified a protein present in the mesh-like membrane structure (the basement membrane) associated with tumour and vessel softness, and good survival of cancer patients. The researchers tested if removing this protein from the basement membrane would enhance the spread of cancer, which it did, and if supply of this protein would reduce cancer spread, which it did. They proceeded to show that the levels of this protein (netrin-4) already present in basement membrane of organs may determine cancer spread even before cancer develops, ...

New microscopy analysis allows discovery of central adhesion complex

New microscopy analysis allows discovery of central adhesion complex
2021-02-16
Cells of organisms are organized in subcellular compartments that consist of many individual molecules. How these single proteins are organized on the molecular level remains unclear, because suitable analytical methods are still missing. Researchers at the University of Münster together with colleagues from the Max Planck Institute of Biochemistry (Munich, Germany) have established a new technique that enables quantifying molecular densities and nanoscale organizations of individual proteins inside cells. The first application of this approach reveals a complex of three adhesion proteins that appears to be crucial for the ability of cells to adhere to the surrounding tissue. The research results have been published in the journal Nature ...

The water surface is a fantastic place for chemical reactions

2021-02-16
Using an advanced technique, scientists from the RIKEN Cluster for Pioneering Research have demonstrated that a chemical reaction powered by light takes place ten thousand times faster at the air-water interface--what we usually call the water surface--than in the bulk of the water, even when the light has equivalent energy. This finding could help our understanding of the many important chemical and biological processes that take place at the water surface. Water is the most important liquid in nature, and research has shown that there is in fact something special about the interface. For reasons that were not well understood, it appears that some chemical reactions take place readily when the molecules are partly in the water, but not when they are fully ...

People with and without AD have a different threshold for elective revascularisation

2021-02-16
The risk of both mortality and rehospitalisation after an elective revascularisation procedure for coronary artery disease is similar for people with and without Alzheimer's disease (AD), but people with AD had worse outcomes after an emergency procedure, according to a new study from the University of Eastern Finland. Previous studies have investigated the effectiveness of revascularisation in persons with cognitive disorders, but only in terms of short-term outcomes and in acute care settings, and they also have not accounted for electivity. Similar to previous ...

Challenge to anorexia nervosa treatment guidelines

Challenge to anorexia nervosa treatment guidelines
2021-02-16
New analysis published in The Lancet Psychiatry has shown a lack of strong evidence to support current guidance on psychological therapies for treating anorexia nervosa over expert treatment as usual. The findings highlight a need for further research and support a call for individual trial data to be made available so the benefits of treatments in specific patient populations can be better understood. Conducted by an international team of clinical experts and researchers, the analysis included 13 randomised controlled trials and a total of 1049 patients. The studies compared psychological therapies to treatment as usual in adults receiving outpatient treatment for anorexia. The trials measured eating disorder ...

First humans in Tasmania must have seen spectacular auroras

First humans in Tasmania must have seen spectacular auroras
2021-02-16
Drilling a 270,000-year old core from a Tasmanian lake has provided the first Australian record of a major global event where the Earth's magnetic field 'switched '- and the opportunity to establish a precedent for developing new paleomagnetic dating tools for Australian archaeology and paleosciences. "This is the first study of this kind in Australia since pioneering studies in the 1980s," said author Dr Agathe Lisé-Provonost, a McKenzie Fellow from the School of Earth Sciences at the University of Melbourne. "Just two lakes in north-east Australia previously provided such "full-vector" record, where both the past directions and the past intensity of the Earth magnetic field are obtained from the same cores." Published in the journal Quaternary Geochronology, Chronostratigraphy ...

Dual character of excitons in the ultrafast regime: atomic-like or solid-like?

Dual character of excitons in the ultrafast regime: atomic-like or solid-like?
2021-02-16
Milan, 15 February 2021 - Excitons are quasiparticles which can transport energy through solid substances. This makes them important for the development of future materials and devices - but more research is needed to understand their fundamental behaviour and how to manipulate it. Researchers at Politecnico di Milano in collaboration with the Institute of Photonics and Nanotechnologies IFN-CNR and a theory group from the Tsukuba University (Japan) and the Max Plank Institute for the Structure and Dynamics of matter (Hamburg, Germany), have discovered that an exciton can simultaneously adopt two radically different characters when it isstimulated ...
