JAMA study: Effectively managing pain with depression

Researchers developed a strategy to improve both depression and pain management by closely monitoring antidepressant therapy and providing pain self-management training. The study found that this approach led to substantial improvements in both conditions, with benefits lasting six months after treatment was completed.

John P. Cogswell, Ph.D., receives 2009 Alzheimer Award

John P. Cogswell, PhD, has been awarded the 2009 Alzheimer Award for his work on identifying microRNA changes in Alzheimer's disease brain and CSF, which yields putative biomarkers and insights into disease pathways. His research highlights the potential of microRNAs to aid clinical diagnosis.

Toward cheap underwater sensor nets

Researchers at UC San Diego are building low-cost, low-power modems for short-range underwater networking, enabling higher sampling rates and more frequent data collection. The project aims to create a network of underwater sensors that can provide real-time environmental data, revolutionizing the way we understand our natural world.

Scientists find city rats are loyal to their 'hoods

A study found that rats in Baltimore form distinct neighborhoods, with each community spanning little more than an average alley. Rats rarely migrate, but neighborhood eradication efforts may backfire by encouraging rodents to repopulate other areas and spread disease.

BUSM researchers find no adjustment method fully resolves confounding by indication

Researchers at Boston University School of Medicine found that conventional methods to adjust for confounding, such as restriction and multivariable regression, leave residual confounding because of unmeasured factors. Propensity scores and instrumental variable methods have limitations in resolving confounding by indication.

NEJM study finds drug-eluting stents more effective than bare-metal stents in heart attack patients

A landmark study published in NEJM found that paclitaxel-eluting stents significantly reduce target lesion revascularization and binary angiographic restenosis rates compared to bare-metal stents. The study showed a lower rate of ischemia-driven target-lesion revascularization at 12 months with the use of paclitaxel-eluting stents.

JNCI May 26 issue tip sheet

Researchers discovered that CIP2A expression is associated with reduced overall survival in gastric cancer patients, as well as increased proliferation and anchorage-independent growth. Meanwhile, a RasGAP-derived peptide has been shown to improve responses to chemotherapy in mouse models of colon cancer.

Viruses are sneakier than we thought

Researchers found that Kaposi's sarcoma-associated herpesvirus uses polyadenylation to block normal gene expression in cells. The virus' SOX protein aberrantly lengthens mRNA poly(A) tails, sending a signal to the cell that its messages are wrong and holding them back.

Lifelong cancer risk for patients treated for childhood cancer

A new study found that childhood cancer survivors have a significantly increased risk of developing second primary cancers throughout their lives. The research, published in the Journal of the National Cancer Institute, analyzed data from 47,697 people diagnosed with cancer before age 20 and found a higher incidence rate of new primary...

Lessons from the vaccine-autism wars

The vaccine-autism debate persists despite scientific consensus, fueled by internet misinformation and declining public trust. Pediatrician Paul Offit's efforts to set the record straight have been hindered by celebrity anti-vaccine advocates like Jenny McCarthy.

Green tea extract shows promise in leukemia trials

Researchers at Mayo Clinic have found that patients with chronic lymphocytic leukemia (CLL) can tolerate high doses of green tea extract EGCG, leading to a significant reduction in lymphocyte count. The study also showed that many participants experienced regression of CLL symptoms, particularly those with enlarged lymph nodes.

Capturing the birth of a synapse

Researchers from the University of Oregon and University of California, Davis, have identified a locking mechanism that allows neurons to form synapses, essential for transmitting information. This discovery sheds light on autism development, a brain disorder affecting social and communication abilities.
