(Press-News.org) A reason for these findings could be due to the fact that Parkinson's patients often also have many risk factors for a severe course of Covid-19. For the first time, the cross-sectional study provides detailed nationwide data. The research team led by Professor Lars Tönges reports in the journal Movement Disorders of 4 May 2021.
Nationwide analysis of hospital data
The team headed by Lars Tönges has analysed data on Parkinson's treatment in 1,468 hospitals. The data were taken from nationwide databases in which information on the treated diseases and of treatments carried out in hospitals is publicly collected, for example by the Institute for the Hospital Remuneration System or the Federal Statistical Office.
A comparison between the period of the first wave from 16 January to 15 May 2020 with the same period of the previous year showed that overall hospital treatments due to Parkinson's disease had decreased by almost one third during the first wave. At the peak of the wave, the number of cases even fell by a good 70 per cent. The reason for this was, on the one hand, the patients' concern about contracting the SARS-CoV-2 virus in hospital. On the other hand, many non-emergency treatments were postponed to ensure intensive care capacity.
Frailty increases the risk
The analysis also showed that Covid-19 was more common in hospitalised patients with Parkinson's disease than in patients without Parkinson's disease, especially in those of advanced age over 65 years or with particularly severe Parkinson's disease. It was also confirmed that Parkinson's patients who had Covid-19 were more likely to be affected by the known high-risk conditions. "Parkinson's patients may be at particular risk for severe Covid-19 due to frailty, which increases with age and advanced disease stages," explains Lars Tönges. "Lung function may be impaired by common comorbidities and respiratory muscle weakness associated with Parkinson's. In addition, dysphagia makes people more susceptible to pneumonia."
More deaths than in the previous year
In the nationwide cross-sectional study conducted by the neurologists in Bochum, the hospital mortality of Covid-19 patients with Parkinson's disease was higher than that of Covid-19 patients without Parkinson's disease, especially in those between 75 and 79 years of age. The Parkinson's patients who died with Covid-19 were more likely to have chronic kidney disease and were more likely in a later stage of the disease compared to survivors. "Remarkably, more Parkinson's patients died in hospitals in 2020 than in 2019, which may also be due to circumstances associated with overall Covid-19 disease management," concludes Tönges.
"The study illustrates the need to ensure optimal treatment of Parkinson's patients despite the current pandemic," stress the authors. Telemedical services, for example, can also support this in the future. Data on the developments during the second and third waves are expected soon.
Parkinson's disease
Parkinson's disease is one of the most common neurological disorders. It reduces mobility, fine motor skills, balance and the ability to walk. Depression, sleep disorders and memory problems can also be associated with the disease. It mainly affects people in the second half of life and is more common in men. Several people affected by Parkinson's have concomitant diseases such as coronary heart disease, high blood pressure or kidney disease. "Since precisely these are significant risk factors for a severe course of Covid-19, the question arose whether inpatients with Parkinson's also develop a severe course of Covid-19 more frequently or die from it," explains lead author Dr. Raphael Scherbaum from the RUB hospital.
At the same time, the Covid-19 pandemic also affects the healthcare of all Parkinson's sufferers. "Rising numbers of patients show how important hospitalisation is, especially during illness crises, for example after a fall or when medication is not effective enough," says Scherbaum. How much the first wave of the pandemic reduced the care of patients with Parkinson's was not known until now.
Corona research at RUB
RUB has been conducting research on Covid-19 since the beginning of the coronavirus pandemic - across all disciplines. This means that not only medicine and life sciences are involved, but also, for example, psychology, sociology, law, education and history. An overview of the research projects can be found online.

Blocked blood vessels in the brains of stroke patients prevent oxygen-rich blood from getting to cells, causing severe damage. Plants and some microbes produce oxygen through photosynthesis. What if there was a way to make photosynthesis happen in the brains of patients? Now, researchers reporting in ACS' Nano Letters have done just that in cells and in mice, using blue-green algae and special nanoparticles, in a proof-of-concept demonstration.
Strokes result in the deaths of 5 million people worldwide every year, according to the World Health Organization. Millions more survive, but they often experience disabilities, such as difficulties with speech, swallowing or memory. The most common cause is a blood vessel blockage in the brain, and the best way to ...

WASHINGTON, DC (May 19, 2021) - Human genetics and genomics contributed $265 billion to the U.S. economy in 2019 and has the potential to drive significant further growth given major new areas of application, according to a new report issued today by the American Society of Human Genetics (ASHG). The findings indicate that this research and industry sector has seen its annual impact on the U.S. economy grow five-fold in the last decade and outlined at least eight areas of expanding impact for human health and society. ASHG commissioned and funded the report and is grateful for generous additional contributions from Invitae and Regeneron. ...

An international research team led by Professor Charles Gauthier from the Institut national de la recherche scientifique (INRS) has discovered a new molecule with potential to revolutionize the biosurfactant market. The team's findings have been published in Chemical Science, the Royal Society of Chemistry's flagship journal.
Surfactants are synthesized from petroleum and are the main active ingredient in most soaps, detergents, and shampoos. Biosurfactants, produced by bacteria, are safer and can replace synthetic surfactants.
Rhamnolipid molecules are some ...

Pregnant women made only modest dietary changes after being diagnosed with gestational diabetes, according to a study by researchers at the National Institutes of Health. Women with gestational diabetes are generally advised to reduce their carbohydrate intake, and the women in the study did cut their daily intake of juice and added sugars. They also increased their intake of cheese and artificially sweetened beverages. However, certain groups of women did not reduce their carbohydrate intake, including women with obesity, had more than one child, were Hispanic, had a high school degree or less, or were between the ages of 35-41 years.
The study was led by Stefanie N. Hinkle, Ph.D., of the Epidemiology Branch at NIH's Eunice Kennedy Shriver ...

WASHINGTON (May 19, 2021)--Early online support for the Boogaloos, one of the groups implicated in the January 2021 attack on the United States Capitol, followed the same mathematical pattern as ISIS, despite the stark ideological, geographical and cultural differences between their forms of extremism. That's the conclusion of a new study published today by researchers at the George Washington University.
"This study helps provide a better understanding of the emergence of extremist movements in the U.S. and worldwide," Neil Johnson, a professor of physics at GW, said. "By identifying hidden common patterns in what seem to be completely unrelated movements, topped with a rigorous mathematical description of how they develop, our ...

DALLAS, May 19, 2021 -- Steps to ensure safety and mitigate the spread of COVID-19 have had some unintended consequences on the management of chronic conditions such as high blood pressure, a leading cause of heart disease and health disparities in the United States. COVID-19 has disproportionately affected people from different racial and ethnic groups, those who are from under-resourced populations and communities that face historic or systemic disadvantages. Discussions and research are ongoing to address what many experts label as long-existing inequities in the U.S. health system, according to information published today in the Journal of the American Heart Association, an open access journal of the American Heart Association.

Chronic exposure to second-hand smoke results in lower body weight and cognitive impairments that more profoundly affects males, according to new research in mice led by Oregon Health & Science University.
The study published today in the journal Environmental Health Perspectives.
"The hope is that we can better understand these effects for policymakers and the next generation of smokers," said lead author Jacob Raber, Ph.D., professor of behavioral neuroscience in the OHSU School of Medicine. "Many people still smoke, and these findings suggest that that the long-term health effects can be quite serious for people who are chronically exposed to second-hand smoke."
The research examined daily exposure of 62 mice over a period of 10 months. Researchers used a specially designed ...

A new article from Liverpool ocular researchers demonstrates that small uveal (intraocular) melanomas are not always harmless, as the current paradigm suggests.
Instead, a reasonable proportion of them have molecular genetic alterations, which categorises them as highly metastatic tumours. The article recommends that they should not be observed but rather treated immediately, to improve patients' chances of survival.
The paper shows that uveal melanoma patients with small tumours, when treated within a certain time frame in Liverpool, do indeed have improved outcomes.
The study was undertaken by researchers ...

Invasions by alien insect and animal species have much in common with outbreaks of infectious diseases and could tell us a great deal about how pandemics spread, according to a research paper published today.
Biological invasions, where animals, insects, plants and microorganisms are transported around the globe by humans, are becoming more common and have a global annual cost of at least £118billion.
An investigation by an international team of scientists, including the University of Leeds' School of Biology, says the emergence of human diseases share many of the same challenges as species invasions and that studying them together could provide solutions.
Co-author of the report, Dr Alison M. Dunn, a Professor of Ecology in the School of Biology, ...

Monroe Carell Jr. Children's Hospital at Vanderbilt has launched a study to determine the impact of a predictive model for identifying pediatric patients at risk for developing blood clots or venous thromboembolisms (VTEs).
The study uses advanced predictive analytics to inform medical teams of patients at risk for blood clots before they happen.
"Hospital-associated blood clots are an increasing cause of morbidity in pediatrics," said the study's principal investigator, Shannon Walker, MD, clinical fellow of Pediatric Hematology-Oncology at Children's Hospital.
While these events are more rare among children than they are among adults, Walker noticed that blood clot development was on the rise.
"The reason children get blood clots is very different ...
