Spiral waves break hearts: Importance of communication between cardiac cells is demonstrated

Researchers investigate how electrical impulses travel through cardiac tissue and how impaired cell communication affects heart health. They develop a computer model that shows how electrical activity spreads like a fire in a forest, and find that spiral waves breaking up into multiple spirals may be similar to the patterns that cause ...

Cancer-causing drug safe and effective in treating eye disease

Researchers found that high-dose, short-term chlorambucil treatment resulted in sustained inflammation reduction for 77% of patients with severe, non-infectious uveitis. The study's findings suggest that chlorambucil may become a preferred treatment option for these patients.

Misclassification of death may influence perceived value of cancer screening

A study found that two forms of bias in cause-of-death classification affect the results of randomized trials on cancer screening. Sticky-diagnosis bias biases against screening, while slippery-linkage bias biases in favor of screening. The authors suggest using all-cause mortality to accurately assess the value of screening.

Other highlights in the Feb. 6 issue of JNCI

Researchers found that response rates, survival rates, and quality-of-life outcomes are similar between elderly patients (ages 70+) and younger patients with non-small-cell lung cancer. Additionally, studies report an increased risk of lung cancer after Hodgkin's disease treatment, especially in smokers, and analyzed cost-effectiveness...

Dartmouth research examines the value of cancer screening

A Dartmouth study found biases in cancer screening trials that may have overestimated its benefits, suggesting a need for alternative mortality analysis methods. The research recommends using all-cause mortality alongside disease-specific mortality to ensure accurate assessment of screening's value.

Discovery of bacterial 'touch sensor' could lead to biofilm treatments

Biologists at Princeton University discovered a protein that initiates biofilm formation in E. coli bacteria, using a 'touch sensor' mechanism to sense solid surfaces. This finding suggests disrupting this sensing mechanism could be an effective strategy for developing new antibacterial agents targeting biofilms.

Former astronaut Aldrin, Purdue engineers planning Mars hotels

Researchers plan to use cycler spacecraft, which would constantly ferry people and materials between Earth and Mars, to enable human exploration and colonization of the Red Planet. The cyclers would rotate slowly to create artificial gravity and provide comfortable accommodations for passengers on long trips.

Hormone therapy may boost quality of life, say Stanford researchers

A Stanford study shows that hormone therapy can improve mental health and reduce depression in women experiencing hot flashes, but may have negative effects on those without symptoms. The research suggests that women should discuss their individual risks and benefits with their doctor before making a decision.

Tanning lamps may increase risks of skin cancers

A statewide study found that people who used tanning lamps were 2.5 times more likely to develop squamous cell carcinoma and 1.5 times more likely to develop basal cell carcinoma than non-users. The risk of these skin cancers increased with younger age at use.

Tanning devices may contribute to incidence of common skin cancers

A new study found that individuals who used tanning devices were 2.5 times more likely to develop squamous cell carcinoma and 1.5 times more likely to develop basal cell carcinoma compared to those who did not use them. The risk of these cancers increased with the age at which participants started using tanning devices.

Brief exercise improves mental performance in people with chronic lung disease

A new study found that a single session of moderately intense exercise improves cognitive function in people with chronic obstructive pulmonary disease (COPD), particularly in verbal fluency. The effects are cumulative, suggesting that regular physical activity is necessary to maintain mental benefits.

Elderly lung cancer patients tolerate aggressive chemotherapy as well as younger patients

A retrospective analysis of 574 patients with non-small cell lung cancer found that older patients tolerated chemotherapy regimens comparable to younger patients. However, psychological distress and neutropenia were more prevalent in the elderly population. The study suggests that functional status is a key factor in determining treatm...

Satellites vs. mosquitoes: Tracking West Nile Virus in the U.S.

A NASA-funded study utilizes satellite data on temperature and vegetation to forecast West Nile Virus transmission and identify high-risk areas. The analysis reveals that mosquito populations thrive in warmer, wetter conditions, allowing researchers to pinpoint disease hotspots and make predictions about future outbreaks.
