A national study suggests that the standard heel-stick test is not effective at identifying cytomegalovirus (CMV) infection in newborns, with only 17 out of 60 infected children identified. The test's limited value has major public health implications, as congenital CMV infection is a leading cause of hearing loss in children.
A North Carolina State University researcher found that bacteria from insect bites can be passed to human babies by the mother, causing chronic infections. The study suggests a possible link between maternal infection with bacteria like Bartonella and birth defects.
Researchers at Children's National Hospital found that carbon monoxide levels increase during routine general anesthesia in young children. To reduce this risk, anesthesiologists recommend using specific absorbents and avoiding low-flow anesthesia to minimize exposure.
Researchers found that men with metabolic syndrome had twice as low blood H2S levels as lean men, while those with diabetes had four times lower levels. This reduction in H2S was associated with higher blood pressure, increased insulin resistance and damage to small blood vessels.

Researchers at the University at Buffalo found that vitamin D supplements, diet, geographic location, demographic information, and lifestyle cannot accurately predict vitamin D concentrations in blood. This means that relying on proxy measures like food intake or latitude of residence to assess cancer risk is not reliable.
A new study reveals that individual fibrin fibers play a crucial role in equitably distributing strain load and strengthening the entire network. The research found that fibers subjected to significant strain stiffen to resist stretch, thereby reducing strain concentrations.
A blood test measuring C-reactive protein (CRP) levels may help assess colon cancer risk, according to a Vanderbilt University Medical Center study. High CRP levels were found to be associated with a 2.5-times greater risk of colon cancer in women.
A study found that DNA analysis of dried blood samples from newborns did not effectively identify an infection causing congenital CMV, leading to sensorineural hearing loss. Current methods for screening newborns for this infection have low sensitivity and specificity.
A study found that the traditional 'heel stick' test is not an effective screening tool for cytomegalovirus (CMV) infection in newborns. The test, which involves pricking a baby's heel and analyzing dried blood samples, was unable to detect CMV DNA in up to 40% of infected babies.
