Global study sets new risk-based standard to personalize chemotherapy for colon cancer
After surgery for lymph-node positive colon cancer (stage III), some patients may only need half of the long-standing standard course of chemotherapy.

Two combination therapies shrink melanoma brain metastases in more than half of patients
A combination regimen of two immunotherapies and another of two targeted therapies each significantly shrank metastatic brain tumors in at least 50 percent of patients in separate multi-center clinical trials presented today at the 2017 ASCO Annual Meeting by principal investigators from The University of Texas MD Anderson Cancer Center.

Web-based system for self-reporting symptoms helps patients live longer
A randomized clinical trial of 766 patients shows that a simple intervention -- a web-based tool that enables patients to report their symptoms in real time, triggering alerts to clinicians -- can have major benefits, including longer survival.

Development of a novel vaccine for Zika
Research presented by Farshad Guirakhoo, Ph.D., Chief Scientific Officer, GeoVax, Inc., at the ASM Microbe 2017 meeting showed a new Zika virus vaccine that gives 100 percent protection in mice.

Cancer patients who systematically reported their symptoms lived longer
Cancer patients who reported their symptoms to their cancer care providers using a web-based survey lived longer than those patients who did not, according to a study led by a University of North Carolina Lineberger Comprehensive Cancer Center researcher.

Penn effort to expand trials of olaparib leads to new treatment options for patients with advanced BRCA-related breast cancer
Six years ago an international team of physician scientists led a charge to advance clinical testing of the PARP inhibitor olaparib in cancer patients with known inherited BRCA mutations.

Electronic patient-reported symptom monitoring associated with increased survival among patients
The integration of electronic patient-reported outcomes into the routine care of patients with metastatic cancer was associated with increased survival compared with usual care, according to a study published by JAMA.

Emergency medicine in space: Normal rules don't apply
Experts at this year's Euroanaesthesia congress in Geneva (June 3-5) will discuss the unusual and challenging problem of how to perform emergency medical procedures during space missions.

Bed partners may unintentionally contribute to the perpetuation of insomnia
Preliminary results from a new study show that partners of people who have insomnia may try to be supportive by engaging in a range of behaviors that unintentionally contradict treatment recommendations.

Nothing to fear for 'good Samaritan' doctors who assist medical emergencies
Experts at this year's Euroanaesthesia congress in Geneva (June 3-5) will look at what can happen when doctors are called on to help with a medical emergency (for example on board an aircraft, a so called 'good Samaritan' act) and says that and says that as long as they do their best, they can be confident it is very unlikely that legal action will be taken against them.

Abiraterone delays metastatic prostate cancer growth by 18 months, extends survival
Adding abiraterone acetate (Zytiga) plus prednisone to standard hormonal therapy for men newly diagnosed with high-risk, metastatic prostate cancer lowers the chance of death by 38 percent.

Increasing susceptibility of Staphylococcus aureus in the United States
Findings from a study that looked at susceptibility trends of Staphylococcus aureus in US hospital patients showed that key antibiotics used to treat the bacteria became more active over the course of the study, a rare occurrence.

New millimeter-wave technology could make future vehicles much safer
Hiroshima University and Mie Fujitsu Semiconductor Limited (MIFS) today announced the development of a low-power millimeter-wave amplifier that feeds on 0.5 V power supply and covers the frequency range from 80 GHz to 106 GHz.

Vapor from novel tobacco hybrid device minimally impacts human cells
New laboratory data reveal that vapor from a novel hybrid tobacco heating product (THP) iFuse and two standard THPs produced little or no effect on human cells in biological testing.

New technology dives deep into the cancer genome
In a study of 124 patients with advanced breast, lung, and prostate cancers, a new, high-intensity genomic sequencing approach detected circulating tumor DNA at a high rate.

Steady decrease in severe health problems for childhood cancer survivors
Treatments for childhood cancer are often intense and carry the risk of lifelong health problems for survivors.

Olaparib slows growth of BRCA-related metastatic breast cancer
Findings from a phase III clinical trial of about 300 women may introduce PARP inhibitors as a new type of treatment for breast cancer.

Routine genomic testing is feasible, but only a subset of patients benefit
Genomic testing of tumor samples can enable personalized treatment selection, where targeted treatments are matched to genetic changes in the tumor.

Antibiotic-resistant bacteria in ready-to-eat foods
Research presented at the ASM Microbe 2017 meeting by Bryan Sanchez of California State University-Northridge in Northridge, Calif., show that antibiotic-resistant bacteria are present in many ready-to-eat foods such as fresh produce and dairy products and may serve as a source of human exposure to antibiotic-resistant bacteria.

Zika virus successfully diagnosed from semen
Research presented at ASM Microbe 2017 by experts at the Fertility and Cryogenics Lab shows a reliable clinical assay that can detect the Zika virus from semen samples.

Babies born to mothers with sleep apnea have higher risk of adverse neonatal outcomes
A new study is the first to demonstrate a higher risk of congenital anomalies and resuscitation at birth in newborns of mothers who have obstructive sleep apnea.

New disposable, wearable patch found to effectively detect sleep apnea
Results of a definitive clinical trial show that a new, disposable diagnostic patch effectively detects obstructive sleep apnea across all severity levels.

Bio-based p-xylene oxidation into terephthalic acid by engineered E. coli
KAIST researchers have established an efficient biocatalytic system to produce terephthalic acid (TPA) from p-xylene (pX).

Abiraterone slows advanced prostate cancer, helps patients live longer
A clinical trial of nearly 2,000 men shows that adding abiraterone acetate (Zytiga) to a standard initial treatment regimen for high-risk, advanced prostate cancer lowers the relative risk of death by 37 percent.

Natural Caesarean section is safe, popular and feasible and is not encouraging maternal requests for C-section births
An expert speaking at this year's Euroanaesthesia congress in Geneva (June 3-5) will say that 'Natural Caesarean Section' -- in which women enjoy enhanced contact and bonding with their baby just as they would in a vaginal birth -- is safe, popular and feasible, and is not encouraging mothers to request C-section birth when it is not medically necessary.

New drug shows durable efficacy across diverse pediatric and adult cancers
Scientists may have developed the first targeted, oral, tumor-type agnostic therapy -- a cancer medicine that works comparably well across many kinds of cancer, regardless of patient age.
