A study performed with the INMA birth cohort and the European HELIX project has revealed reproducible associations between exposure to multiple chemical pollutants and changes in metabolic processes during pregnancy. The results will help researchers to understand how environmental exposures can affect the health of pregnant women and their babies

A nosebleed, also known as epistaxis, is the common occurrence of bleeding from the nose. It is usually noticed when the blood drains out through the nostrils. There are two types: anterior (the most common), and posterior (less common, more likely to require medical attention). Sometimes in more severe cases, the blood can come up the nasolacrimal duct and out from the eye. Fresh blood and clotted blood can also flow down into the stomach and cause nausea and vomiting.
A radioisotope used for diagnosing and treating thyroid cancer and hyperthyroidism, iodine-131 (I-131), is now being produced in the United States for the first time in almost 30 years. It is made at the University of Missouri Research Reactor (MURR) in Columbia. The center recently shipped its first batch.
Some brain-injured people left with disorders of consciousness unable to communicate or respond, such as people in a coma nevertheless show normal brain responses to spoken language as measured through the scalp by electroencephalography (EEG).
Differences in the cells that give skin its resilience and strength during wound repair may explain why individuals heal differently, according to a new Yale study published Nov. 23 in the journal Science. Fibroblasts, the cells that form the protein structure beneath the surface of the skin, were once thought to be fairly uniform in their function.
The Ohio State University Wexner Medical Center and the Arthur G. James Cancer Hospital and Richard J. Solove Research Institute are collaborating with Nationwide Children’s Hospital to bring the first proton therapy treatment facility to central Ohio.
Researchers at University Putra Malaysia found a relationship between some markers of inflammation in the body and the aggressiveness of certain malignant tumors. They conducted full body scans of 31 people with malignant tumours—including cancers of the lung, esophagus, colon, and breast—using a machine that combines positron emission and computed tomography (PET/CT).
Recently, the bioactive properties of marine collagen and marine collagen hydrolysates have been demonstrated. Although there is some literature assessing the general chemical features and biocompatibility of collagen extracts from marine sponges, no data are available on the biological effects of sponge collagen hydrolysates for biomedical and/or cosmetic purposes.
A new biomarker assay may detect celiac disease and monitor its progress, new research suggests. "We identified immunogenic epitopes of the tTG-DGP (tissue transglutaminase-deamidated gliadin-derived peptide) complex and found that an assay to measure the immune response to epitopes accurately identified patients with celiac disease, as well as patients with mucosal healing," the authors write in Gastroenterology, online October 17.
In a new evidence-based clinical guideline, the American Academy of Pediatrics (AAP) recommends isotonic intravenous fluids (IVFs) with appropriate potassium chloride and dextrose for most children aged 28 days to 18 years who require maintenance IVFs.
