(Press-News.org) Bethesda, MD (March 21, 2023) — The American Gastroenterological Association (AGA) has released new clinical guidance to help physicians and patients identify if unexplained digestive symptoms are due to alpha-gal syndrome, a food allergy that is caused by lone star tick bites. The AGA Clinical Practice Update was published today in Gastroenterology.
Alpha-gal syndrome is an allergy that causes your body to react to eating meat from mammals and products made from mammals. Symptoms usually start 2-6 hours after eating the mammalian meat or food.
Clinicians should consider alpha-gal syndrome in patients with unexplained gastrointestinal symptoms of abdominal pain, diarrhea, nausea and vomiting, particularly those who live or have lived in an alpha-gal–prevalent area (this includes the Southeast, mid-Atlantic, Midwest and East Central U.S. regions). For patients with suspected alpha-gal, there is a blood test that looks for immunoglobulin E antibodies (IgE) to alpha-gal. Patients with these antibodies may have alpha-gal allergy. The main treatment for alpha-gal allergy is to not eat foods that contain alpha-gal. This includes mammalian meat, fat and products made from them.
About Alpha-gal syndrome
Alpha-gal syndrome is an allergy that causes your body to respond badly to ingesting mammalian products; meat from mammals or products made from mammals such as cheese, butter, milk, cream, gelatin, etc. Mammals are animals that have hair, such as cows, pigs and deer. Symptoms usually start 2-6 hours after eating the mammalian meat or food. The alpha-gal allergy can cause symptoms of the gastrointestinal tract (digestive system) like stomach pain, diarrhea (loose stool), nausea or upset belly, and vomiting (throwing up). It can also cause hives (an itchy rash), flushing of the skin, swelling of the face, or fainting. Learn more about alpha-gal syndrome in the AGA GI Patient Center.

Forests reduce health risks, new global report confirms
2023-03-21
Forests, trees and green spaces play a vital role in ensuring a healthy life for all on a global scale.
The health benefits of forests and trees, ranging from physical and mental well-being to overall mortality reduction, far outweigh the adverse effects on health. As health threats, such as forest fires, are mainly caused by human activities, urgent action is needed.
In order to address health challenges, it is important to recognize the close links between human health and the health of other species, of ecosystems, and of the planet as a whole.
Vienna, March, 21, 2023 - The global scientific evidence of the multiple types of benefits ...
ASBMB cautions against drastic immigration fee increases
2023-03-21
The American Society for Biochemistry and Molecular Biology sent recommendations to the U.S. Citizenship and Immigration Services related to the agency’s proposed changes to petition processing fees. The USCIS proposed increasing its filing fees for employment-based visas by up to 2,050%, a measure intended to remedy financial deficits at USCIS and ramp up hiring to improve services. The ASBMB expressed concern about how “the proposed rule is likely to harm the retention of highly skilled foreign-born scientific researchers.”

A new sight for the electrochemical stability in halide electrolytes
2023-03-21
They published their work on February in Energy Material Advances.
"Constructing an efficient ionic/electronic framework is crucial for the development of high-performance solid-state batteries," said Dr. Chuang Yu, a professor at the State Key Laboratory of Advanced Electromagnetic Engineering and Technology at Huazhong University of Science and Technology. "Currently, the application of solid-state batteries with inorganic electrolytes is challenging because most solid electrolytes have an unsatisfactory low oxidation potential."
According to Dr. Yu, halide electrolytes have been found to be cathode-stable materials with relatively wide electrochemical ...
Study confirms nitrate can release uranium into groundwater
2023-03-21
Eight years ago, the data was sound but only suggestive, the evidence strong but circumstantial.
Now, the University of Nebraska–Lincoln’s Karrie Weber and colleagues have experimentally confirmed that nitrate, a compound common in fertilizers and animal waste, can help transport naturally occurring uranium from the underground to groundwater.
Their new research backs a 2015 Weber-led study showing that aquifers contaminated with high levels of nitrate — including the High Plains Aquifer residing beneath Nebraska — also contain uranium concentrations far exceeding a threshold set by the Environmental Protection Agency. Uranium concentrations above that EPA threshold ...
PNAS announces six 2022 Cozzarelli Prize recipients
2023-03-21
WASHINGTON, DC – The Editorial Board of the Proceedings of the National Academy of Sciences (PNAS) has selected six papers published by PNAS in 2022 to receive the Cozzarelli Prize, an award that recognizes outstanding contributions to the scientific disciplines represented by the National Academy of Sciences (NAS). Papers were chosen from more than 3,200 research articles that appeared in the journal last year and represent the six broadly defined classes under which the NAS is organized. Additionally, the Editorial ...
Using optics to trace the flow of microplastics in oceans
2023-03-21
Microplastics are tiny plastic particles less than 5 mm in diameter that have emerged as a novel marine environment pollutant. Microplastics usually result from a breakdown of larger plastic debris but can also be generated from plastic microbeads used in personal care products. Over the years, there has been a significant buildup of microplastic pollutants in our oceans, with a recent estimate that the world’s oceans contain over 24.4 trillion pieces of microplastics weighing between 82,000 and 578,000 tons. It is highly likely that ...
First results from ESO telescopes on the aftermath of DART’s asteroid impact
2023-03-21
Using ESO’s Very Large Telescope (VLT), two teams of astronomers have observed the aftermath of the collision between NASA’s Double Asteroid Redirection Test (DART) spacecraft and the asteroid Dimorphos. The controlled impact was a test of planetary defence, but also gave astronomers a unique opportunity to learn more about the asteroid’s composition from the expelled material.
On 26 September 2022 the DART spacecraft collided with the asteroid Dimorphos in a controlled test of our asteroid deflection capabilities. The impact took place 11 million kilometres away ...
Obesity risk may pass from mothers to daughters
2023-03-21
WASHINGTON—Women with obesity may share risk for the disease with their daughters, but not their sons, according to a new study published in the Endocrine Society’s Journal of Clinical Endocrinology & Metabolism.
Obesity is a common, serious and costly disease affecting nearly half of the adults and 20 percent of children in the United States. It costs an estimated $173 billion in medical care costs. People with obesity are at higher risk of developing diabetes, high blood pressure, heart ...
New program for veterans with high cholesterol, associated cardiovascular disease
2023-03-21
DALLAS, March 21, 2023 — More than 2 million veterans are living with atherosclerotic cardiovascular disease (ASCVD) and require management of their high cholesterol, according to the Department of Veterans Affairs (VA). Left unaddressed, high cholesterol increases the chance of experiencing heart attack and stroke. To control high cholesterol among veterans, the American Heart Association, the world’s leading nonprofit organization focused on heart and brain health for all, in collaboration with the VA, ...
An integrated approach to cool: how evaporation and radiation can cool the world
2023-03-21
Large-scale, effective, and passive: these descriptions are aptly given to the integrated radiative and evaporative chiller (IREC), designed and tested by researchers at Tsinghua University in Beijing, China. The goal of this technology is to come up with an energetically affordable method of cooling to aid in the rising consumption of energy while still minimizing carbon emissions through the process.
“Energy scarcity is a universal challenge to global development. The demand for ...
