Brain changes occurred independent of evolutionary rearrangements in the braincase

The human brain is about three times the size of the brains of great apes. This has to do, among other things, with the evolution of novel brain structures that enabled complex behaviors such as language and tool production.

New study solves oldest case of deafness in human prehistory

An international team of researchers including faculty at Binghamton University, State University of New York, has published a new study examining a 430,000-year-old cranium of a human ancestor that was previously described as deaf, representing the oldest case of deafness in human prehistory.

Study evaluates role of PET/CT in selecting candidates for peptide receptor radionuclide therapy

A new study published in The Journal of Nuclear Medicine evaluated the role of 68Ga-DOTATATE positron emission tomography/computed tomography in selecting neuroendocrine tumor patients who may benefit from peptide receptor radionuclide therapy.

Chemical-sensing cells in the gums protect the mouth from infections

Newly discovered chemical-sensing cells in the gums protect the mouth by standing guard against infections that damage soft tissue and destroy the bone that supports the teeth, report researchers from the Monell Chemical Senses Center in an animal study published this week in Nature Communications.

Mummies show atherosclerosis was prevalent in ancient times

A new study published in the American Heart Journal used spectroscopic imaging techniques to ‘see’ fatty plaques in the arteries of ancient mummies. This shows that the people of ancient times also had a high incidence of clogged arteries, showing that heart disease is of very old lineage.

Algorithm helps physicians to assess whether stroke patients are candidates for clot-removing procedure

An algorithm developed by faculty at The University of Texas Health Science Center at Houston can help physicians outside of major stroke treatment centers assess whether a patient suffering from ischemic stroke would benefit from an endovascular procedure to remove a clot blocking an artery.

Heart disease was bigger issue for human ancestors than originally thought, study reveals

A new imaging study of the mummified arteries of people who lived thousands of years ago revealed that their arteries were more clogged than originally thought, according to a proof-of-concept study led by a researcher with The University of Texas Health Science Center at Houston.

Radiation therapy reduces episodes of deadly rapid heart rhythm

A single high dose of radiation aimed at the heart significantly reduces episodes of a potentially deadly rapid heart rhythm, according to results of a phase one/two study at Washington University School of Medicine in St. Louis.

Too much Vitamin D could be harmful to bones

Vitamin D – an essential for healthy bones and calcium in the body, is prepared by the body when the skin is exposed to sunlight. A daily exposure of around 10 to 15 days is considered to be adequate for fulfilling the needs of vitamin D in the body.

New ESC guidelines for diagnosis and management of pulmonary embolism published

The European Society of Cardiology Guidelines on acute pulmonary embolism are published online today in European Heart Journal, and on the ESC website. They were developed in collaboration with the European Respiratory Society.

Global air pollution linked to increased emphysema cases

A new study funded by the NIH says that increasing rates of the chronic lung condition called emphysema are linked to breathing polluted air over a long period. The progression of emphysema, a condition more commonly linked to smoking, is now also being attributed to polluted air. Air pollution is already known to be associated with lung and cardiovascular disease.

Scientists 3D print full-scale functioning heart components for the first time

Researchers have developed a new 3D bioprinting method that can produce any part of the heart, from tiny capillaries through to full-scale heart components.

Study finds worrisome increase in medical imaging during pregnancy

Use of medical imaging during pregnancy increased significantly in the United States, a new study has found, with nearly a four-fold rise over the last two decades in the number of women undergoing computed tomography CT scans, which expose mothers and fetuses to radiation. Pregnant women are warned to minimize radiation exposure.

Early neuroimaging essential for Zika-exposed infants

Seventy-one of 110 Brazilian infants at the highest risk for experiencing problems due to exposure to the Zika virus in the womb experienced a wide spectrum of brain abnormalities, including calcifications and malformations in cortical development, according to a study published July 31, 2019 in JAMA Network Open.

Lymph node response to treatment can predict survival in patients with esophageal cancer

Optimal methods for predicting treatment efficacy in patients with esophageal cancer are seriously lacking. But now, researchers from Japan have found a useful alternative to existing methods for predicting patient outcomes.

New medical imaging device could help cut time and cost of procedures

Researchers have completed a successful clinical trial, managing to detect and image radioactive tracers used in PET and in SPECT scans at the same time, with the hope of enabling doctors to scan patients for abnormalities in shorter times while reducing the amount of radiation patients would be exposed to.
