Three-site study highlight effectiveness of FEND nasal calcium rich salts
2021-01-12
(Press-News.org) In a paper published in Molecular Frontiers Journal, researchers from Cambridge, Massachusetts and Bangalore, India study the effectiveness of FEND product to significantly improve airway hygiene by reducing and suppressing respiratory droplets potentially containing airborne pathogens and other contaminants. The study's findings further highlight why the FEND product is an important new daily hygiene protocol that joins century-old hand washing, masking and distancing measures as a fourth protective layer of defense against aerosolized particles.
The new study examined two nasal salines: FEND, a drug-free nasal saline hygiene formulation comprised of calcium chloride and sodium chloride in distilled water, and Simply Saline by Arm & Hammer, a commercially available nasal spray of isotonic sodium chloride, as a control. The study involved 253 human volunteers, ranging from ages 10-70 years old from three different locations: Grand Rapids Community College in Grand Rapids Michigan, Cape Cod Academy in Cape Cod Massachusetts, and Bangalore Baptist Hospital in Bangalore, India (a location of relatively high airborne particulate burden). The geographic and demographic distributions were chosen to determine the impact of airway hygiene in highly polluted versus less polluted environments, including elementary, secondary and college learning environments.
The research examined the individual's respiratory droplets --particles generated in human airways during breathing that may contain contaminants, and that can evade masks and linger within indoor environments --and found a reduction in number on exhalation by up to 99% following airway hygiene using the FEND product. Reduction of exhaled particles following an isotonic nasal saline spray control was statistically insignificant. The research also found that exhaled particles were considerably higher and efficacy of airway hygiene greatest in Bangalore India, where particulate levels of air pollution exceeded those at the other sites of the study by at least ten-fold. . "It was incredible to see how FEND reduced exhaled aerosols in our participants," said Dr. Carolin Elizabeth George of Bangalore Baptist Hospital in India, another co-author of the FEND study. "In countries like India, where public health measures for Covid-19 have serious livelihood implications, FEND is a practical alternative. It is worthwhile to investigate its effect further on viral and bacterial burden in low and middle income countries where pollution is high - as the success can have farfetched positive implications."
Since launch of the FEND product in late October 2020, airway hygiene has begun to be used in work, home, and educational settings threatened by COVID-19, and other lower-airway respiratory threats. Both Grand Rapids Community College and Cape Cod Academy have integrated FEND into the schools' hygiene protocols for students and staff for 2021. At Bangalore Baptist Hospital in India, follow-on human trials are underway evaluating the efficacy of FEND in Covid positive patients. Further research in India will explore the use of FEND in low-income neighborhoods where access to existing hygiene protocols is limited.
"We are encouraged by these latest data," said co-author Dr. David Edwards, whose research at Harvard and within Harvard spinout technology companies has, since the first SARS outbreak, explored the action of physiological salts for reducing respiratory drops as a safe and inexpensive means to reduce exposure to airborne pathogens. "Bringing to over 300 human volunteers evaluated this year at six sites in the USA and India, the results of this study underline the value of a fourth human hygiene for assuring hygienic safety during and after the pandemic -- daily airway hygiene as an efficacious and inexpensive complement to hand sanitizing, masks and social distancing."

CORVALLIS, Ore. - A resemblance to moss, lichens and fungi made for fantastic cover by a new genus and species of cylindrical bark beetle described by an Oregon State University College of Science researcher.
"If you can't beat your enemies or run away, then hide, and that is what this Cretaceous beetle is doing," said OSU's George Poinar Jr. "He is hiding under a spectacular camouflage of his own making, allowing him to blend into a mossy background."
Poinar, an international expert in using plant and animal life forms preserved in amber to learn more about the biology and ecology of the distant past, and collaborator Fernando ...

Research on cycad trees in Colombia, Guam, and the Philippines has illuminated how knowledge of their branching behavior may benefit conservation decisions for the endangered plants. In a study published in the December issue of the journal Horticulturae, scientists from the University of Guam and the Montgomery Botanical Center in Florida show that the number of times a cycad tree produces a branch can be used to infer the sex of the tree. The findings have practical applications for use of the sexual dimorphism that is described.
Cycads are unique seed-producing plants. Conservation actions are being implemented for many species around the world as cycads are being threatened by human activity.
The arborescent cycad stem is constructed using ...

Ten years of data from Australia, New Zealand and Canada reveals a drop in drowning deaths among people under 20 - but a large increase in drowning for adolescent females and First Nations peoples.
Associate Professor Richard Franklin from James Cook University in Queensland, Australia, said an international collaboration of researchers looked at drowning in the under 20s between 2005 and 2014.
"Globally, drowning is a leading cause of unintentional death among children and young people, with the greatest toll among children under the age of five years. Many more children are impacted by non-fatal drowning, some experiencing long-term health impacts," said Dr Franklin.
He said children aged 0-19 years account for an average ...

PHILADELPHIA--Patient-reported outcomes have become a critical part of improving surgical care because of their ability to capture patient experiences, such as quality of life and satisfaction, that can help inform treatment. However, for patients undergoing abdominal hernia repair -- a common procedure performed on about 400,000 patients a year in the United States -- a tool to effectively and practically measure those outcomes has not been widely accepted and implemented by clinics.
Now, researchers from the division of Plastic Surgery in the department of Surgery in the Perelman School of Medicine at the University of Pennsylvania, have successfully developed, tested, and implemented a first-of-its-kind, patient-informed ...

Osaka - Organic light-emitting diode (OLED) displays are now very popular features of many mainstream products including smartphones and televisions. OLEDs have the advantages of being low cost, light, flexible, and easy to modify, making them ideal display materials. However, current OLEDs that achieve commercially viable quantum efficiencies contain rare metal atoms such as iridium and platinum that increase costs and reduce sustainability. Now, an international team including researchers from Osaka University has reported the best performing heavy-atom-free OLED of its kind.
Although OLEDs that do not contain heavy atoms--such as rare metals and halogens--are ...

SINGAPORE, 12 January 2021 - Researchers from Duke-NUS Medical School in Singapore and Columbia University in the US have solved how Wnt proteins, which play a fundamental role in cell proliferation and differentiation, hitch a ride to travel from their cellular factory to the cell surface. Drugs that interfere with Wnt transport, like the made-in-Singapore anti-cancer drug ETC-159, can be exploited to treat diseases with excess Wnt signalling, such as cancer and fibrosis.
"Since excessive Wnt signalling can drive cancer, supress immunity and trigger fibrosis, ...

WASHINGTON--The Endocrine Society is calling on policymakers to include government negotiation as part of an overall strategy to reduce insulin prices in its updated position statement published today in The Journal of Clinical Endocrinology & Metabolism.
More than 34 million Americans have diabetes, and another 88 million are at risk for developing the disease. The cost of insulin has nearly tripled in the past 15 years, and a lack of transparency in the drug supply chain has made it challenging to identify and address the causes of soaring costs.
Federal law currently prohibits Medicare, which accounts for a third of all drug spending, from negotiating directly with pharmaceutical companies over drug prices. Legislation empowering the ...

To properly monitor and help curb the spread of COVID-19, several millions of diagnostic tests are required daily in just the United States alone. There is still a widespread lack of COVID-19 testing in the U.S. and many of the clinical diagnostics protocols require extensive human labor and materials that could face supply shortages and present biosafety concerns.
The current gold standard for COVID-19 diagnostic testing in the U.S., developed by the U.S. Centers for Disease Control and Prevention (CDC), is quantitative PCR-based (qPCR) molecular tests that detect the presence of the viral ...
