Several major childhood allergies may all stem from the community of bacteria living in our gut, according to a new study led by researchers at the University of British Columbia and BC Children's Hospital.
"These are technically different diagnoses, each with their own list of symptoms, so most researchers tend to study them individually," says Dr. Charisse Petersen, co-senior author on the paper and postdoctoral fellow in the Turvey lab."But when you look at what is going wrong at aFor the study, researchers examined clinical assessments from 1,115 children who were tracked from birth to age five.
Many factors can shape the infant gut microbiota, including diet, how we are born, where we live, and our exposure to antibiotics. For example, antibiotics may wipe out sensitive bacteria, while breastfeeding tends to replenish and provide necessary food for bacteria in the infant gut. The researchers examined how these types of influences affected the balance of gut microbiota and the development of allergies.
Now the researchers hope to leverage the findings to inform treatments that correct an imbalanced gut microbiota and could potentially prevent allergies from developing.

Researchers find key for transforming cancer cells to muscle in rhabdomyosarcomaFor six years, Professor Christopher Vakoc's lab at Cold Spring Harbor Laboratory has been on a mission to transform sarcoma cells into regularly functioning tissue cells. Sarcomas are cancers that form in connective tissues such as muscle. Treatment often involves chemotherapy, surgery, and radiation—procedures that are especially tough on kids. If doctors could transform cancer cells into healthy cells, it would offer patients a whole new treatment option—one that could spare them and their families a great deal of pain and suffering.

Researchers study barriers and facilitators to accessing health care in rural MissouriRural Missourians often face more disparities in health outcomes than their urban and suburban counterparts, in part from challenges accessing health care—a problem amplified in recent years by a growing physician shortage. But a new study at the University of Missouri found that health and health care organizations are increasingly offering basic social services, such as transportation, housing, food, and mental health support, as they recognize these services contribute to a person's overall health.

Researchers develop a novel algorithm for mitigating COVID-19 spread in shipsThe COVID-19 pandemic has drastically affected human lives and the global economy. In particular, cruise ship companies around the world are among the worst hit industries, with ships becoming a hotbed of viral infection owing to their confined environment. With the economy slowly recovering in the post COVID-19 period, ship companies hope to return to normal operations by adopting a sustainable management model that prioritizes the health of ship passengers.
