How to save cost for esophageal varices?

A study published in the World Journal of Gastroenterology found that reloading a multiband ligator instead of using a new one can significantly reduce the cost of treating esophageal varices. The procedure, which involves reusing the same band ligator for multiple sessions, resulted in a 58% reduction in costs.

Study concludes no racial disparities in long-term outcomes in recipients of liver transplants

A new study published in the Journal of the American College of Surgeons reveals that long-term survival and liver rejection rates are equivalent for African-American liver transplant patients as compared to patients of other races. The study suggests that race is not a predictor of survival, contrary to previous findings.

Study: Doctors not always sure when to treat BP in people with diabetes

A study found that even when patients with diabetes present with high blood pressure, there's only a 50-50 chance of receiving treatment. Uncertainty about the patient's blood pressure and other medical issues contribute to this 'clinical inertia'. More systematic guidelines for monitoring blood pressure in people with diabetes are needed

JAMA publication features study on depression and head and neck cancer

A University of Nebraska Medical Center-led pilot study found that antidepressants significantly reduced the risk of depression in head and neck cancer patients. The study, led by Drs. William Lydiatt and Bill Burke, showed that only 15% of patients who took antidepressants experienced depression, compared to 50% of those who did not.

New mid-infrared lasers show doubled efficiency

Researchers have doubled the efficiency of infrared lasers in the mid-infrared wavelength range, which could enable next-generation laser-based defense systems and commercial applications like trace chemical analysis and pollution monitoring. The advancements were achieved through improvements to material quality, design, and fabrication.

Software designers strut their talent at cost of profit, says Management Insights study

A new Management Insights study by Enno Siemsen reveals that software designers intentionally create complex products to advance their careers. Companies are struggling to cope with increasing design complexity, and the study suggests moving compensation agreements towards short-term project success.

Researchers find smallpox drug may also target adenovirus

Researchers at Saint Louis University have made a breakthrough finding that a smallpox drug, hexadecyloxypropyl-cidofovir (CMX001), successfully targets adenovirus in animal models. CMX001 provided protection from the virus when administered prophylactically or therapeutically and reduced viral load to undetectable levels.

The photonic beetle

University of Utah chemists have discovered the ideal photonic crystal structure, dubbed the "champion" crystal, in the shimmering green scales of a Brazilian weevil beetle. The scale material has a diamond-like structure that can manipulate light efficiently, but its chitin composition makes it unsuitable for long-term use.

Teaching evolution: Legal victories aren't enough

A national survey of teachers found that one in eight high school biology teachers present creationism as a scientifically valid alternative to Darwinian evolution. The majority of teachers spend less than five hours on human evolution, suggesting pressure from the community may influence teaching practices. Raising certification stand...

Family history may be associated with susceptibility to shingles

A study of 504 patients with herpes zoster found that individuals with a family history of the condition were 4.35 times more likely to develop shingles. The authors suggest targeting at-risk individuals based on their family history to decrease the risk and health care expenditures associated with herpes zoster morbidity.
