New research at UH Rainbow studies the impact of face masks on heart ra

The study compared participants at rest and during physical activity

2021-02-24
(Press-News.org) CLEVELAND, Ohio - Researchers at University Hospitals Rainbow Babies & Children's Hospital (UH Rainbow) published new findings today that wearing a face mask - either a cloth mask or a surgical mask - did not impair the ability of subjects to get air in and out of their bodies.

The study measured heart rate, transcutaneous carbon dioxide tension, and oxygen levels in 50 adult volunteers at the conclusion of six 10-minute phases: Sitting quietly and then walking briskly without a mask; sitting quietly and then walking briskly while wearing a cloth mask; and sitting quietly and then walking briskly while wearing a surgical mask. The median age of participation was 33 years and 32 percent of participants indicated they have a chronic health condition such as asthma.

In the study, not a single participant developed a low level of oxygen or high level of carbon dioxide in the blood while wearing a cloth or surgical mask either at rest or during exercise. According to the study's principal investigator, Steven L. Shein, MD, Division Chief of Pediatric Critical Care Medicine at UH Rainbow Babies & Children's Hospital, the risk to the general adult population of having significantly abnormal levels of oxygen or carbon dioxide when wearing a cloth or surgical mask is near-zero.

"We know face masks help to prevent the spread of COVID-19, but we also know people have concerns of discomfort or impaired breathing while wearing them," says Dr. Shein, who is also the Linsalata Chair in Pediatric Critical Care and Emergency Medicine, and Associate Professor of Pediatrics at Case Western Reserve University School of Medicine. "Our hope is these findings will reassure people that their body is able to adequately get oxygen in and carbon dioxide out while wearing a face covering."

INFORMATION:

The new study titled "The effects of wearing facemasks on oxygenation and ventilation at rest and during physical activity" published in PLOS ONE journal is under embargo until 2 p.m. ET on Feb. 24: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0247414

New technology shows potential to improve potency and durability benefits in gene therapy

2021-02-24
WATERTOWN, Mass. - Gene therapy has traditionally been conceptualized as a one-time, curative treatment option; however, research shows that there may be a need for subsequent doses years after initial treatment. While adeno-associated viral (AAV) vectors are a core part of this powerful therapeutic approach, they present two key challenges in gene therapy. The first challenge is their immunogenicity. In gene therapy, the formation of neutralizing antibodies (Nabs) in response to AAV vector administration precludes retreatment of a patient due to the potentially dangerous immune response that would occur after a second or third administration of the therapy. The second obstacle relates to their durability. AAV vectors ...

Scientists describe earliest primate fossils

Scientists describe earliest primate fossils
2021-02-24
A new study published Feb. 24 in the journal Royal Society Open Science documents the earliest-known fossil evidence of primates. A team of 10 researchers from across the U.S. analyzed several fossils of Purgatorius, the oldest genus in a group of the earliest-known primates called plesiadapiforms. These ancient mammals were small-bodied and ate specialized diets of insects and fruits that varied by species. These newly described specimens are central to understanding primate ancestry and paint a picture of how life on land recovered after the Cretaceous-Paleogene extinction event 66 million years ago that wiped out all dinosaurs -- except for birds -- and led to the rise of mammals. Gregory Wilson Mantilla, a University of Washington professor of biology and curator of vertebrate ...

Revive the map: 4D building reconstruction with machine learning
2021-02-24
A research team from Skoltech and FBK (Italy) presented a methodology to derive 4D building models using historical maps and machine learning. The implemented method relies on the geometric, neighbourhood, and categorical attributes to predict building heights. The method is useful for understanding urban phenomena and changes contributing to defining our cities' actual shapes. The results were published in the MDPI Applied Sciences journal. Historical maps are the most powerful source used to analyze changes in urban development. Nevertheless, maps represent the 3D world ...

Record-high Arctic freshwater will flow to Labrador Sea, affecting local and global oceans

Record-high Arctic freshwater will flow to Labrador Sea, affecting local and global oceans
2021-02-24
Freshwater is accumulating in the Arctic Ocean. The Beaufort Sea, which is the largest Arctic Ocean freshwater reservoir, has increased its freshwater content by 40% over the past two decades. How and where this water will flow into the Atlantic Ocean is important for local and global ocean conditions. A study from the University of Washington, Los Alamos National Laboratory and the National Oceanic and Atmospheric Administration shows that this freshwater travels through the Canadian Archipelago to reach the Labrador Sea, rather than through the wider marine passageways that connect to seas in Northern Europe. The open-access study was published Feb. 23 ...

Diabetes patients use of mobile health app found to improve health outcomes, lower medical costs

2021-02-24
Emerging smart mobile health (or mHealth) technologies are changing the way patients track information related to diagnosed conditions. A new study examined the health and economic impacts of mHealth technologies on the outcomes of diabetes patients in Asia. The study concluded that compared to patients who did not use mHealth applications, patients who used the apps had better health outcomes and were able to regulate their health behavior more effectively. They also had fewer hospital visits and lower medical costs. The study was conducted by researchers at Carnegie Mellon University (CMU) and New York University ...

Study identifies strengths and challenges of responding to dual disasters

2021-02-24
New Orleans, LA -- A new study of how the 2020 major hurricanes and the COVID-19 pandemic affected each other as well as disaster response found that although prior experience enabled community-based organizations to respond to the pandemic, the pandemic is also creating new challenges to preparing for and responding to natural disasters. The research is published in the International Journal of Environmental Research and Public Health, available here. "Two major crises hit Louisiana and coastal communities in the Southeastern United States in 2020 - a significant increase in the frequency and severity of hurricanes, and the COVID-19 pandemic," says Benjamin Springgate, MD, MPH, Chief of Community & Population Medicine at ...

A combination therapy for treating severe neurological childhood disorders

2021-02-24
A study aiming to develop a new therapeutic technique could bring a revolution in our approach to treating rare, fatal Sanfilippo syndrome, a disorder that affects children as young as 2 years old and leads to childhood dementia and premature death. "We are using a combination of gene therapy, stem cells and small molecules to restore metabolic defects in the patient's brain cells" says Dr. Alexey Pshezhetsky, Professor at CHU Ste-Justine and lead GlycoNet Investigator on this project. "First results in the mouse models of the disease are very encouraging." Sanfilippo syndrome belongs to a group of rare diseases known as lysosomal storage disorders. The syndrome occurs in ...

Bearded seals are loud - but not loud enough

2021-02-24
ITHACA, N.Y. - During mating season, male bearded seals make loud calls to attract a mate. How loud? Well, even their "quiet" call can still be as ear-rattling as a chainsaw. These elaborate vocalizations are essential for bearded seal reproduction, and have to be loud enough to be heard over the cacophony of their equally loud brethren. But in the rapidly changing Arctic soundscape, where noise from industrial activities is predicted to dramatically increase in the next 15 years, bearded seals may need to adjust their calling behavior if they are ...

New study charts the complexity of SARS-CoV-2 neutralization

2021-02-24
Washington, DC - February 24, 2021 - In the absence of effective treatments for COVID-19, many countries have approved the therapeutic use of blood plasma from recovering patients because it contains antibodies against the coronavirus. But not every type of antibody can neutralize the virus and render it noninfectious. New research published this week in mSphere, an open-access journal of the American Society for Microbiology, explores variation in virus neutralization capabilities, which can vary widely by type of antibody. "What we need for plasma therapy is not only high levels of antibodies but also high neutralization capability," said virologist Michael Schindler, Ph.D, at University Hospital Tübingen, ...

Scientists suggested using 'defective' diamonds in x-ray optics

2021-02-24
X-rays are used to study the atomic and microstructure properties of matter. Such studies are conducted with special accelerator complexes called synchrotrons. A synchrotron source generates powerful electromagnetic radiation with a wavelength equal to fractions of a nanometer. Some X-rays are reflected from the atomic planes of a crystal and some go through the crystal plane that plays the role of a beam-splitter (or the so-called semitransparent mirror). If the radiation passes through monochromators-optical devices that consist of two or more ideal crystals - its optimal exit wavelength can be regulated. ...
