(Press-News.org) Amsterdam, July 20, 2021 - Well over six million people globally have been diagnosed with Parkinson's disease (PD), which has an enormous impact on the lives of patients, their families, and caregivers and is incurring mounting costs for society. This special supplement to the Journal of Parkinson's Disease (JPD), guest-edited by noted experts Anat Mirelman, PhD, E. Ray Dorsey, MD, MBA, Patrik Brundin, MD, PhD, and Bastiaan R. Bloem, MD, PhD, reviews how digital technology is being used to reshape research and clinical care in PD.
Digital health technology is an umbrella term that spans a diverse range of applications, including body-fixed wearable sensors, non-contactable domestic sensors, smartphone apps, and videoconferencing and other telemedicine systems that allow for direct remote interaction between patients and healthcare providers.
"Digital health technology is an important and promising field that is beginning to make a real tangible impact on persons with PD," explained Co-Guest Editor Anat Mirelman, PhD, Center for the Study of Movement, Cognition and Mobility, Neurological Institute, Tel Aviv Sourasky Medical Center; and Sackler Faculty of Medicine and Sagol School of Neuroscience, Tel Aviv University, Israel. "This special supplement includes a series of succinct reviews that cover many practical and relevant aspects, such as digital monitoring, telemedicine, digital therapeutics, virtual clinical trials and digital progression biomarkers for clinical trials. All reviews offer both a view of the current state-of-the-art and informed perspectives on future directions."
"Despite the accumulating body of evidence to support the feasibility, utility, and benefits of various digital technology approaches, the use of digital technology in clinical practice has long remained scarce," added Co-Guest Editor and joint JPD Editor-in-Chief Bastiaan R. Bloem, MD, PhD, Radboud University Nijmegen Medical Center; Donders Institute for Brain, Cognition, and Behavior; Department of Neurology, Nijmegen, The Netherlands. "It has taken a contagion to make patients, physicians, and insurers pay better attention. Specifically, the limits on our ability to travel imposed by the ongoing coronavirus pandemic has led to a dramatic increase in the use of digital platforms in a matter of a few months. This change was unprecedented and has been identified as one of the few silver linings of the pandemic."
Important developments highlighted in this supplement include:
The increase in use of digital platforms is transforming neurological care, catalyzing the use of digital technology to maintain continuity of care, and impacting clinical trials. Using wearable sensors, clinicians can still monitor patients' motor symptoms while they are isolated at home and gain insights into behavioral changes and the implications of social distancing on patients' non-motor symptoms.
In clinical research, digital technologies are transforming practice and enhancing the understanding of PD. For example, assessing sleep can now be done in the home, passively, and frequently, expanding the knowledge of sleep disorders in patients with clinically manifest Parkinson's as well as individuals in early stages of the disease.
New tools may also shine a light on features of the disease that have largely been invisible, such as the appraisal of social function, expanded assessments of voice, quantification of tremor, assessment of falls, dyskinesia or freezing of gait, and objective measurement of the response to treatment. This could lead to a better understanding of the disease, its temporal pattern, variability, and impact on individuals bearing its burden.
Technological applications have the potential to reshape the way clinical research is conducted as decentralized trials will expand and even more assessments will transfer from the clinic to the home and mobile devices. Remote digital therapeutics can offer an attractive alternative for intensive interventions such as speech and language therapy, which typically requires frequent visits to clinics.
"There remain significant challenges," noted Dr. Mirelman. "These include the digital divide, the issue of privacy and security, and reimbursement, which requires health insurance companies and other payers to be persuaded by the merits of technology."
"The COVID-19 pandemic has emphasized some of the shortcomings of telemedicine or monitoring approaches, such as the undiminished need for in-person visits, especially for new patients," commented Professor Bloem. "These shortcomings raise yet another question as to what extent digital health technologies will survive when our lives get back to a new normal after this pandemic has resolved.
"We can say with certainty that the digital revolution has definitely started. We can almost be equally certain that this is only the beginning. The future of digital medicine will likely benefit both patients and healthcare in ways that are currently difficult to predict," he concluded.
Parkinson's disease is a slowly progressive disorder that affects movement, muscle control, and balance. It is the second most common age-related neurodegenerative disorder affecting about 3% of the population by the age of 65 and up to 5% of individuals over 85 years of age.

MINNEAPOLIS/ST. PAUL (07/20/2021) -- National data analyzed by University of Minnesota Medical School researchers show that nearly 40 percent of all funds used to pay for medical school are expected to come from family or personal sources and scholarships. The prevalence of these sources, however, varies widely by race and socioeconomic status.
Arman Shahriar, Varun Sagi and Lorenzo Gonzalez, all fourth-year students at the University of Minnesota Medical School, are co-lead authors of the study, which was published today in JAMA Network Open.
"Financing a four-year medical education requires upwards of a quarter-million dollars, and this amount has been rising faster than inflation since the 1960s. Prior to this study, ...
Despite the best efforts of industry to work towards sustainability, most plastics (or polymers) are still made using non-renewable fossil fuels. However, researchers have now found an economical method for producing biobased acrylate resins. The study, published in the journal Angewandte Chemie, shows how all the synthesis steps, from initial building blocks right up to polymerization, can be carried out in a single reactor (one pot), minimizing environmental impact.
Most varnishes, adhesives and paints are made from acrylate resins, which are polymers of acrylic acid esters and methacrylic acid esters. The raw materials that form these ...
The sight of felled trees and logging activity can be jarring for nature lovers, but from those sites can sprout young forest growth that's especially attractive to a familiar inhabitant of wooded areas throughout the Northeast - bats.
New findings from researchers at the UConn College of Agriculture, Health, and Natural Resources, published in Forest Ecology and Management, finds that a number of bat species native to the Northeast are highly active in newly created forest spaces, foraging for food at higher rates than is typical of mature forests.
Little is known about ...
Vaccine hesitancy continues to be a hurdle in the development of widespread immunity within the U.S. population as the COVID-19 pandemic enters its second year.
Researchers at the University of Cincinnati College of Medicine have developed a computerized decision analytic model to compare projected outcomes of three vaccine strategies: a patient opts for a messenger RNA vaccine, a patient decides to get an adenovirus vector vaccine or the patient simply forgoes a vaccine altogether.
Pfizer and Moderna produce mRNA vaccines while Johnson & Johnson manufacture an adenovirus vector vaccine. The decision analytic ...
Surgical scars treated with a molecule called alphaCT1 showed a long-term improvement in appearance when compared to control scars, according to multicenter, controlled Phase II clinical trials - a finding that could help surgeons improve patient outcomes.
Now, a public-private research team led by Rob Gourdie, professor and director of the Center for Vascular and Heart Research at the Fralin Biomedical Research Institute at VTC, has revealed clues about why and how it improves the appearance of scars.
The study, to be published in the August issue of the Federation ...
When it was discovered in the 1980s in Argentina, this hadrosaur was diagnosed with a fractured foot. However, a new analysis now shows that this ornithopod commonly known as the duck-billed dinosaur actually had a tumour some 70 million years ago, as well as two painful fractures in the vertebrae of its tail, despite which, it managed to survive for some time.
This dinosaur, called Bonapartesaurus rionegrensis, was discovered in Argentinean Patagonia in the 1980s, and the first analyses of its fossils indicated an ailment of the foot, possibly a fracture, as the Argentinean palaeontologist Jaime Powell pointed out at the time. The study of this animal then came to a standstill until 2016, when Powell invited another team of scientists to resume ...
The Indian Ocean has been warming much more than other ocean basins over the last 50-60 years. While temperature changes basin-wide can be unequivocally attributed to human-induced climate change, it is difficult to assess whether contemporary heat and freshwater changes in the Indian Ocean since 1980 represent an anthropogenically-forced transformation of the hydrological cycle. What complicates the assessment is factoring in natural variations, regional-scale trends, a short observational record, climate model uncertainties, and the ocean basin's complex circulation.

PHILADELPHIA--Alzheimer's disease and related diseases can still only be confirmed in deceased patients' brains via autopsy. Even so, the development of biomarkers can give patients and their families answers during life: Alzheimer's disease can be accurately detected via peptides and proteins in a patient's cerebrospinal fluids (CSF), which can be collected through a lumbar puncture and tested while the patient is alive. In 2018, a new framework suggested combining three Alzheimer's disease biomarkers in CSF - pathologic amyloid plaques (A), tangles (T), and neurodegeneration (N), collectively called ATN. According to recent research from the Perelman School ...
An international team of researchers led by Kumamoto and Tokyo Universities (Japan) have shown that the L452R mutation of the SARS-CoV-2 spike protein, which is common to two mutant strains (Epsilon and Delta), is involved in cellular immunity evasion via the human leukocyte antigen (HLA) A24, and enhances viral infectivity. HLA-A24 is one of the most prominent HLA-class I alleles, especially in East/Southeast Asian populations, which might make them particularly vulnerable to coronavirus variants with this mutation.
The ongoing novel coronavirus (SARS-CoV-2 or COVID-19) pandemic has, as of June 2021, infected over 150 million and killed over 3.5 million people worldwide. Vaccination drives ...
