Study examines why colon cancer is more deadly in pediatric and young adult patients

Colon cancer is more likely to be lethal in children and young adults than middle-aged adults. In a single-institution study, researchers at The University of Texas MD Anderson Cancer Center, Houston, Tex., found that differences in mortality rates persist regardless of whether pediatric, adolescent, and young adult patients (aged 24 and younger) were born with a predisposition for colon abnormalities or disease and for the first time conclude that young people are more likely to have metastases outside the colon, into the abdominal cavity, when they are diagnosed. Their findings put families, clinicians, and surgeons on alert to be sure abdominal complaints in young people are thoroughly and carefully evaluated when first reported, and aggressively treated if cancer is discovered. Study findings appears in an "article in press" on the Journal of the American College of Surgeons website in advance of print.

Although boomers may not be using those same drugs today, many are taking medications, often several of them. And even if those drugs are legal, there are still risks of interactions and side effects.

Coronavirus: We need to start preparing for the next viral outbreak now

The coronavirus outbreak is officially a crisis—let's not waste it.

What are viruses anyway, and why do they make us so sick?

You may sometimes have felt like you "have come down with a virus," meaning that you became sick from being exposed to something that could have been a virus. In fact, you have a virus—actually, many—all the time. Some viruses cause the common cold, and some are crucial to human survival. New viruses can also emerge, and they typically create illness in humans when they have very recently jumped from another species to humans. As world health leaders try to determine how to respond to the new coronavirus, virus expert Marilyn J. Roossinck answers a few questions:

Is pain in your body or mind? How the answer can help guide your treatment

People often use the phrase "mind over matter" to describe situations where aches and pains in the body are overridden using the mind. A gardener comes in from gardening and is surprised to discover a nasty cut on her hand, something she wasn't aware of while focused on her plants. Or a soldier in Afghanistan is wounded by a bullet but feels little pain until he is safe in the infirmary. If pain was directly and entirely linked to bodily injury, these examples would be impossible. A cut would always lead to mild pain, whereas a gunshot wound would immediately cause severe pain. But this is not always the case.

A better diagnosis of rare diabetes to adapt treatment

Diabetes affects more than 400 million people worldwide and is a major public health problem. Although commonly referred to as a single disease, it actually constitutes a group of metabolic disorders with hyperglycaemia as a common feature. Of all its forms, monogenic diabetes—due to a mutation in one of the genes involved in the management of blood sugar levels—affects 1% to 4% of all cases of diabetes. Often confused with type 1 or type 2 diabetes, more than 90% of monogenic cases are misdiagnosed. A study carried out by scientists from the University of Geneva (UNIGE), the University Hospitals of Geneva (HUG), and the Lithuanian University of Health Sciences in Vilnius with more than 1,200 young diabetics allowed to accurately identify the proportion of monogenic diabetes in the whole pediatric diabetes population. Consequently, treatments were adjusted according to the genetic characteristics of the disease in order to improve patients' quality of life. The results that can be read in the journal Diabetes, highlight the need for precision medicine in the management of metabolic diseases.

Scientists have recovered DNA from a well-preserved horned lark found in Siberian permafrost. The results can contribute to explaining the evolution of sub species, as well as how the mammoth steppe transformed into tundra, forest and steppe biomes at the end of the last Ice Age.

Tools used to study human disease reveal coral disease risk factors

In a study published in Scientific Reports, a team of international researchers led by University of Hawai'i (UH) at Mānoa postdoctoral fellow Jamie Caldwell used a statistical technique typically employed in human epidemiology to determine the ecological risk factors affecting the prevalence of two coral diseases—growth anomalies, abnormalities like coral tumors, and white syndromes, infectious diseases similar to flesh eating bacteria.

Why do whales migrate? They return to the tropics to shed their skin, scientists say

Whales undertake some of the longest migrations on earth, often swimming many thousands of miles, over many months, to breed in the tropics. The question is why—is it to find food, or to give birth?

Brain cells protect muscles from wasting away

While many of us worry about proteins aggregating in our brains as we age and potentially causing Alzheimer's disease or other types of neurodegeneration, we may not realize that some of the same proteins are aggregating in our muscles, setting us up for muscle atrophy in old age.

DNA-tagging strategy for early detection of disease signatures

Researchers can uncover how proteins interact with other proteins with far greater sensitivity and in a more natural context than conventional methods, thanks to an analytic technique developed by a RIKEN team. This will make it easier to discover the roles that protein-coding genes play and to diagnose conditions such as autoimmune diseases.

How do we protect our unique biodiversity from megafires?

This summer's devastating Australian fires and their continuing impact on biodiversity serve as a stark reminder of the challenges in nature conservation as we head into an increasingly volatile future driven by climate change.

Forest management that factors in stream distance would help protect arthropods

The structure of vegetation and stream distance are important factors to consider in order to protect the biodiversity of forest arthropods, as stated in an article now published in the journal Forest Ecology and Management. The study concludes that farther from a river course, the conditions are better for the communities of arthropods in the forests, since they need a cool and wet microclimate.

'Feline grimace scale' published

When your cat folds back its ears, closes its eyes, puts its whiskers forward or tucks its head between the shoulders, it's most likely a sign that it's feeling pain. But how much pain?

Antibiotics in animals: More research urgently needed

A special issue of Animal Health Research Reviews turns the spotlight on the science underlying this growing crisis—looking at the evidence base for using antibiotics to prevent illness in beef and dairy cattle, swine, and broiler poultry.

New torula yeast product as digestible as fish meal in weanling pig diets

Starting weanling pigs off with the right diet can make all the difference for the health and productivity of the animal. A new University of Illinois study shows amino acids from a new torula yeast product are more digestible by young pigs than amino acids from fish meal.

Deciphering the mechanism that determines organ size and shape

A study by IRB Barcelona's Development and Growth Control Laboratory, headed by ICREA researcher Marco Milán, reveals how Dpp and Wg morphogens regulate organ proportions and patterning of the fly wing through independent mechanisms. Given that these morphogens are present in vertebrates, these results are highly significant for understanding the development and growth of human limbs. "The regulatory mechanism that we describe in this study may pave the way to new research lines on malformations and congenital diseases in humans," says Marco Milán.

Study reveals hidden risks of estuary development for young salmon

A Simon Fraser University-led research team has found significant evidence that human activity in estuaries is impacting juvenile Pacific and Atlantic salmon. The team's review of 167 peer-reviewed studies (from an initial search of 13,000) identified negative impacts from several stressors, including the effects of flood-protecting tidal gates, pollution and habitat modification.

The strategy of cells to deal with the accumulation of misfolded proteins is identified

A new article by the Oxidative Stress and Cell Cycle research group at UPF identifies the main strategy of cells to deal with the accumulation of misfolded proteins. In the paper, published today in the journal Cell Reports, the Schizosaccharomyces pombe yeast model has been used to investigate the protein quality control process. The study was led by Elena Hidalgo, and postdoctoral researchers Margarita Cabrera and Susanna Boronat are its first authors.

Transporter mutation alters cell energy

The cotransporter NKCC1 moves sodium, potassium and chloride ions across the cell membrane and has roles regulating cell volume, epithelial transport and neuronal excitability.
