Risk factors for the development of food allergy in infants and children

JAMA Pediatrics

2026-02-09

(Press-News.org) About The Study: In this meta-analysis, the most credible risk factors associated with development of childhood food allergy are a combination of major and minor risk factors, including early allergic conditions (atopic march/diathesis), delayed allergen introduction, genetics, antibiotic exposure, demographic factors, and birth-related variables.

Organizational factors to reattract nurses to hospital employment

2026-02-09

About The Study: This cross-sectional study of 4,043 registered nurses (RNs) who recently left a hospital staff nurse job found opportunities for reattracting an existing RN workforce if hospitals are willing to address organizational issues driving RNs away. Many nonretired RNs, particularly those not currently employed, reported being very likely to return to work. The top factors to increase their likelihood of returning were adequate staffing, flexible scheduling, and better wages or benefits. Corresponding Author: To ...

What drives food allergies? New study pinpoints early-life factors that raise risk

2026-02-09

A new study from McMaster University involving 2.8 million children around the world has revealed the most important early-life factors that influence whether a child becomes allergic to food. The study, one of the largest of its kind to examine food allergies, furthers our understanding of how allergies develop, concluding that a combination of genetic, environmental, microbial and social factors influence allergies, rather than a single cause. To come to their findings, researchers carried out a systematic review and meta-analysis of 190 studies on childhood food allergy, including those that confirmed allergy using gold-standard food challenge testing. The study, published ...

Early diagnosis key to improving childhood cancer survival

2026-02-09

A major study by UCL and Fondazione IRCCS Istituto Nazionale dei Tumori in Milan (INT) researchers has for the first time shown in detail how far children’s cancer has spread at diagnosis in a way that can be compared between countries. While poorer survival following late-stage diagnosis is well recognised, the study is the first to show that differences in tumour stage at diagnosis may explain why childhood cancer survival varies between some European regions and tumour types. Published in JAMA Network Open, the researchers analysed ...

Microbiomes interconnect on a planetary-scale, new study finds

2026-02-09

In remembrance of Peer Bork In a new study published in Cell, scientists in the Bork Group at EMBL Heidelberg reveal that microbes living in similar habitats are more alike than those simply inhabiting the same geographical region. By analysing tens of thousands of metagenomes, the team found that while most microbes adapt to a specific ecosystem, a rarer subset known as ‘generalists’ can thrive across very different habitats. Known for being ecologically tolerant, generalists are capable of ...

Let’s get on pancreatic cancer’s nerves

2026-02-09

Pancreatic cancer has a lot of nerve. Notoriously tricky to detect, the disease also often resists traditional therapy. So, researchers are urgently looking for new ways to disrupt tumor formation. Though scientists know that the nervous system can help cancer spread, its role in the disease’s earliest stages remains unclear. “One phenomenon that is known is called perineural invasion,” says Jeremy Nigri, a postdoc in Professor David Tuveson’s lab at Cold Spring Harbor Laboratory (CSHL). “This means cancer cells will migrate within the nerve and use the nerve as a way to metastasize.” Now, Nigri and his colleagues at CSHL have discovered ...

Intermittent fasting cut Crohn’s disease activity by 40% and halved inflammation in randomized clinical trial

Contact: Rachel Peifer rpeifer@crohnscolitisfoundation.org Intermittent Fasting Cut Crohn’s Disease Activity by 40% and Halved Inflammation in Randomized Clinical Trial First study of time-restricted feeding in people with IBD suggests a role in long-term remission February 9, 2026 — A new randomized controlled study funded by the Crohn’s & Colitis Foundation found that time-restricted feeding—a form of intermittent fasting—significantly reduced symptomatic disease activity and systematic inflammation in adults with Crohn’s ...

New study in JNCCN unlocks important information about how to treat recurring prostate cancer

2026-02-09

PLYMOUTH MEETING, PA [February 9, 2026] — New research in the February 2026 issue of JNCCN—Journal of the National Comprehensive Cancer Network found that incorporating information from prostate-specific membrane antigen (PSMA) PET/CT scans may be able to predict progression-free survival (PFS) and guide treatment planning in patients with rising prostate-specific antigen (PSA) levels following removal of the prostate. The researchers used retrospective clinical data from 113 patients treated for prostate ...

Simple at-home tests for detecting cat, dog viruses

2026-02-09

Pet owners want quick answers when their beloved cat or dog is sick. And if these furry friends are experiencing digestive distress, lethargy and fever, it’s important to rapidly rule out serious illnesses like feline panleukopenia (also called feline parvovirus) and canine parvovirus. Now, researchers in ACS’ Analytical Chemistry report improved lateral flow assays for at-home screening. In tests on veterinary clinic samples, the assays demonstrated 100% sensitivity and reproducibility for both parvoviruses. “Feline parvovirus (FPV) and canine parvovirus (CPV) infection can be deadly for pets, and clinical signs alone are often insufficient to ...

New gut-brain discovery offers hope for treating ALS and dementia

2026-02-09

CLEVELAND—A significant discovery by Case Western Reserve University researchers could change how doctors treat two of the most devastating neurodegenerative diseases. The team identified a link between gut bacteria and the deterioration of the brain in Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD). The researchers discovered that certain bacterial sugars cause immune responses that kill cells—and how to prevent it. FTD mainly affects the brain’s frontal and temporal ...

Cognitive speed training linked to lower dementia incidence up to 20 years later

2026-02-09

FOR IMMEDIATE RELEASE Adults age 65 and older who completed five to six weeks of cognitive speed training — in this case, speed of processing training, which helps people quickly find visual information on a computer screen and handle increasingly complex tasks in a shorter time period — and who had follow-up sessions about one to three years later were less likely to be diagnosed with dementia, including Alzheimer’s disease, up to two decades later, according to new findings published today in Alzheimer’s & Dementia: Translational Research and Clinical Interventions. This National Institutes of Health ...
