Satellite gearing up to take EPIC pictures of Earth

The Deep Space Climate Observatory (DSCOVR) satellite is on its way to do something epic. NOAA's spacecraft, sent to monitor space weather, will use its Earth Polychromatic Imaging Camera (EPIC) to capture the entire sunlit face of our planet and collect valuable atmospheric data. EPIC, built by Lockheed Martin, will show the full face of Earth in a single picture, something previously done only by the Apollo 17 astronauts and the Galileo mission on its way to Jupiter. "EPIC will view the whole sunlit side of Earth from L-1, a point approximately one million miles away," Joe Mobilia, EPIC program manager at Lockheed Martin, told astrowatch.net. "Today, images of Earth come from spacecraft in LEO [Low Earth Orbit] or GEO [Geosynchronous Equatorial Orbit], which only sample a portion of the planet, albeit at higher resolutions."

Morphogenesis through flowing tissue

In an in vivo analysis of eye development, researchers at Heidelberg University and the University of Freiburg have gained fundamental new insight into the development of coloboma of the eye, prompting them to revise the classical view of the development of this sensory organ in vertebrates. The team led by developmental and cell biologists Dr. Stephan Heermann and Prof. Dr. Jochen Wittbrodt of the Heidelberg Centre for Organismal Studies (COS) used in vivo 4D microscopy to demonstrate that directed tissue flow transforms the optic vesicle into the optic cup during eye development. This is not only critical for understanding the cause of coloboma ("cat eye syndrome"), but also means that eye development in vertebrates, including humans, is fundamentally different than has been taught for more than 70 years. The results of their research were published the journal eLife.

A study of medication for knee osteoarthritis points the way to new methods for ranking drugs' effectiveness

Maybe you "trust Tylenol" or (like this writer) you're "all Advil." Research proves that both painkillers work, but many of us, including our doctors, can't help but have a preference shaped by experience and perhaps even advertising. Which really does work better? That's what Raveendhara Bannuru, director of the Center for Treatment Comparison and Integrative Analysis at Tufts Medical Center and a research assistant professor of medicine, wanted to find out.

Household income found to be related to preschool attendance in China

Early childhood education has been seen by many as a tool to break the cycle of poverty for developing countries. Yet, despite the more than 82 million children under age 5 living in China today, little is known about the factors contributing to preschool attendance there, particularly in rural areas. This omission is even more salient given that more than 70 percent of mothers in the 25–34 age range with children under the age of 6 in China work outside the home, and household income has consistently been shown to affect child care choices in both developed and developing countries.

New strategies for anesthesia

In operating rooms around the world, machines attached to anesthetized patients blip and bleep, reporting second-by-second accounts of vital organs. Blood circulation and respiration are closely monitored, but the one organ that is drugged, the brain, has no readout. Anesthesiologists simply watch for signs of wakening, says Emery Brown, the Edward Hood Taplin Professor of Medical Engineering and Computational Neuroscience at MIT.

Active surveillance of intermediate-risk prostate cancer associated with decreased survival

An analysis of data on 945 patients with prostate cancer that is managed with active surveillance shows differences in outcomes depending on whether the patient was low or intermediate risk at diagnosis. Compared to patients with low-risk disease, those with intermediate-risk cancer (PSA >10ng/ml or Gleason score 7 or clinical stage T2b/2c) had a nearly four-fold higher chance of dying from prostate cancer within 15 years. The study will be presented at the upcoming 2015 Genitourinary Cancers Symposium in Orlando.

Men who have had testicular cancer are more likely to develop prostate cancer

A case-control study of close to 180,000 men suggests that the incidence of prostate cancer is higher among men with a history of testicular cancer (12.6 percent) than among those without a history of testicular cancer (2.8 percent). Men who have had testicular cancer were also more likely to develop intermediate- or high-risk prostate cancers. The study will be presented at the upcoming 2015 Genitourinary Cancers Symposium in Orlando.

Androgen receptor abnormality may not be associated

Findings from a small prospective study suggest that androgen receptor V7 (or AR-V7) status does not significantly affect response to taxane chemotherapy in men with metastatic castration-resistant prostate cancer (mCRPC). Treatment outcomes were largely similar for the 17 patients with AR-V7-positive prostate cancer and the 20 patients with AR-V7-negative disease included in this analysis. The study will be presented at the upcoming 2015 Genitourinary Cancers Symposium in Orlando.

Early evidence of increase in higher-risk prostate cancers from 2011-2013

An analysis of data on roughly 87,500 men treated for prostate cancer since 2005 finds a notable increase in higher-risk cases of the disease between 2011 and 2013. The retrospective analysis of patient data found the proportion of men diagnosed with intermediate- and high-risk disease increased by nearly 6 percent in those years. While a rise in mortality has not yet been seen, the authors estimate this apparent trend could produce 1,400 additional prostate cancer deaths per year (based on the 2014 estimated number of new prostate cancer cases and the relative survival of patients with low- versus high-risk cancer). They emphasize, however, that the findings must be confirmed through further research. The study will be presented at the upcoming 2015 Genitourinary Cancers Symposium in Orlando.

Facial expression more important to conveying emotion in music than in speech

Regular concert-goers are used to seeing singers use expressive and often very dramatic facial expressions. Indeed, music and speech are alike in that they use both facial and acoustic cues to engage listeners in an emotional experience. McGill researchers wondered what roles these different cues played in conveying emotions.

Gene regulatory path revealed as target for therapy of aggressive pediatric brain cancer

Decline in smoking rates may increase lung cancer mortality

A decline in smoking rates may mean that many people who could have benefited from early detection of lung cancer are dying because they don't qualify for low-dose CT scans, according to a group of Mayo Clinic researchers. Their research appears in the Feb. 24 issue of JAMA, the journal of the American Medical Association.

Findings may help with the management of anticoagulant-related bleeding within the brain

Among patients with oral anticoagulation-associated intracerebral hemorrhage (bleeding within the brain), reversal of international normalized ratio (INR; a measure used to determine the clotting tendency of blood while on medication) below a certain level within 4 hours and systolic blood pressure less than 160 mm Hg at 4 hours were associated with lower rates of hematoma (a localized swelling filled with blood) enlargement, and resumption of anticoagulant therapy was associated with a lower risk of ischemic events without increased bleeding complications, according to a study in the February 24 issue of JAMA.

Gene variant and risk and severity of nerve disorder linked to cancer drug

Children with acute lymphoblastic leukemia who had a certain gene variant experienced a higher incidence and severity of peripheral neuropathy after receiving treatment with the cancer drug vincristine, according to a study in the February 24 issue of JAMA.

Taking NSAIDs with anti-clotting medications and risk of bleeding, CV events

Among patients receiving antithrombotic therapy (to prevent the formation of blood clots) after a heart attack, the use of nonsteroidal anti-inflammatory drugs (NSAIDs) was associated with an increased risk of bleeding and events such as heart attack, stroke or cardiovascular death, even after short-term treatment, according to a study in the February 24 issue of JAMA.

It's tough to shift that weight, studies show

New studies by McMaster University researchers, published in CMAJ Open, have confirmed that people of all ages find it difficult to prevent weight gain; that it is terrifically difficult to get rid of it later and to keep it off once lost. However, even small weight losses can mean better health.

Direct brain neurostimulation for partial onset seizures provides long-term benefit

Piotr Olejniczak, MD, PhD, LSU Health New Orleans Professor of Neurology and Director of the Epilepsy Center, contributed to a study of the long-term effectiveness of the first direct brain responsive neurostimulator for partial onset, or focal, seizures that cannot be controlled with medication. The study found that responsive direct cortical stimulation reduces seizures and improves quality of life over an average of 5.4 years. The study is published in the February 24, 2015, issue of the journal, Neurology.

Stellate cells in the liver control regeneration and fibrosis

Liver fibrosis, which is the progressive formation of scar tissue in the liver, is a massive medical problem. An estimated ten percent of the population is affected by liver fibrosis or its corresponding later stage, liver cirrhosis. A variety of causes can lead to liver fibrosis, the most widely recognized ones being alcohol consumption and virus-induced chronic liver inflammation. Other factors that can lead to scarring in the liver include the use of certain drugs, fatty liver disease and genetic disorders such as iron overload disease. As fibrosis progresses, the liver tissue becomes increasingly nodular, and the disease turns into liver cirrhosis, a dangerous condition that also drastically increases the risk of developing liver cancer.

'Patchwork' ovarian cancer more deadly

Together, nanotechnology and genetic interference may tackle 'untreatable' brain tumors

There are no effective available treatments for sufferers of Glioblastoma multiforme (GBM), the most aggressive and devastating form of brain tumor. The disease, always fatal, has a survival rate of only 6-18 months.

Unexpected outcomes for elderly couples who stop driving

The ability to drive can be central to a person's identity and can be an important expression of independence. When the elderly become unable to drive, due to age or deteriorating health, their emotional well-being can decline as a result of being unable to maintain social relationships or work schedules that require travel by car. Now, a University of Missouri researcher has found that even if just one member of a couple stops driving, negative consequences result for both the driver and non-driver. The researcher recommends that the elderly, and their adult children, carefully discuss and plan for the transition to driving cessation.

Marine oil supplement has positive effects on post-exercise muscle damage

An Indiana University study has revealed that there may be a greater connection between mussels and muscles than previously thought.

Even low-androgen triple-negative breast cancer responds to anti-androgen therapy

A University of Colorado Cancer Center study published today in the journal Molecular Cancer Therapeutics shows that only about 1 percent of triple-negative breast cancer cells in a tumor must be "androgen-receptor-positive" to show benefit from anti-androgen therapies. There are no FDA-approved targeted therapies for triple-negative breast cancer. Clinical trials currently underway are showing promising preliminary results of anti-androgen-receptor therapies against triple-negative breast cancers expressing a higher percentage of androgen-receptor-positive cells.

Teen girls from rural areas more likely to have undiagnosed asthma, be depressed

This study, titled "Enamel Hypomineralization and Structural Defects in Amelotin-deficient Mice," is published in the OnlineFirst portion of the Journal of Dental Research: the journal for dental, oral and craniofacial research.

Patients with mental illness less likely to receive diet, exercise advice

More than half of patients with symptoms of mental illness - and nearly one-third of those who also had diabetes - said their health care providers had never told them to exercise or reduce their intake of dietary fat, according to a new study published in Diabetes Educator.

Cutting-edge technology optimizes cancer therapy with nanomedicine drug combinations

In greater than 90 percent of cases in which treatment for metastatic cancer fails, the reason is that the cancer is resistant to the drugs being used. To treat drug-resistant tumors, doctors typically use multiple drugs simultaneously, a practice called combination therapy. And one of their greatest challenges is determining which ratio and combination—from the large number of medications available—is best for each individual patient.

New health care delivery model for prostate cancer care results in better patient outcomes

A comprehensive, population-based regional health care management program for men with prostate cancer who are members of Kaiser Permanente Southern California has led to improved outcomes, according to a Kaiser Permanente study published today in the journal Urology Practice.

Younger women delay seeking help for heart attacks, study finds

High-energy breakfast with low-energy dinner helps control blood sugar in people with type 2 diabetes

A small new study published in Diabetologia (the journal of the European Association for the Study of Diabetes) shows that, in people with type 2 diabetes, those who consume a high energy breakfast and a low energy dinner have better blood sugar control than those who eat a low energy breakfast and a high energy dinner. Thus adjusting diet in this fashion could help optimise metabolic control and prevent complications of type 2 diabetes. The authors of the study include Professor Daniela Jakubowicz and Professor Julio Wainstein, Wolfson Medical Center, Tel Aviv University, Israel, Professor Bo Ahren, Lund University, Sweden and Professor Oren Froy Hebrew University of Jerusalem, Israel.

Primary care residents unlikely to detect hazardous alcohol use

When it comes to detecting alcohol misuse, newly minted primary care physicians ask the wrong questions at the wrong times, according to a study led by researchers at Wake Forest Baptist Medical Center.

Women twice as likely to see pot as risky: Ten-year decline in perception of marijuana risk

A study on the perceived risk of regularly using cannabis and the characteristics associated with these perceptions found that non-white, low-income women over the age of 50 were most likely to perceive a risk in using the drug. Least likely were those 12 to 25 years old, with a high school diploma or more, and a total family income above $75,000. The study by researchers at Columbia University's Mailman School of Public Health with colleagues at Johns Hopkins University is the first to describe changes across time in perceived risk of regular cannabis use in the U.S. population 12 years and older. Results are published in the journal Drug and Alcohol Dependence.

Pregnant women unmoved by maternity hospital ratings, study suggests

Sunitinib, sorafenib of no benefit in ECOG-ACRIN renal cell trial

Research results highlighted today at the press conference of a major medical meeting report no benefit from the use of either Sutent (sunitinib) or Nexavar (sorafenib) among patients with locally advanced renal cell carcinoma at high risk of recurrence, the ECOG-ACRIN Cancer Research Group (ECOG-ACRIN) announced. Both of these oral drugs are widely used in helping patients with metastatic renal cell carcinoma, commonly called kidney cancer, live longer with their disease.

Simple paper strip can diagnose Ebola and other fevers within 10 minutes

When diagnosing a case of Ebola, time is of the essence. However, existing diagnostic tests take at least a day or two to yield results, preventing health care workers from quickly determining whether a patient needs immediate treatment and isolation.

Disparities in breast cancer care linked to net worth

Household net worth is a major and overlooked factor in adherence to hormonal therapy among breast cancer patients and partially explains racial disparities in quality of care. The findings suggest that physicians, health insurers, and policy makers need to pay more attention to this economic variable to ensure that breast cancer patients receive this potentially life-saving treatment. The study was published recently in the online issue of Journal of Clinical Oncology.

Limited promise in early results from Ebola drug trial

Early results from an Ebola trial using the experimental drug Avigan (favipiravir) showed Monday it was somewhat effective at saving lives if given early in the illness, but not later.

Testing the first portable system for monitoring patients with Parkinson's disease

Parkinson's disease is the second neurodegenerative disease in number of patients after Alzheimer's disease. The Technical Research Centre for Dependency Care and Autonomous Living (CETpD) of the Universitat Politècnica de Catalunya has developed a pioneering portable system for monitoring the motor status of Parkinson's disease patients in real time. The system also determines the status of patients while they are walking or during their daily activities and acts when the person has gait problems such as slowing or freezing. This system is being developed within the European project REMPARK (Personal Health Device for the Remote and Autonomous Management of Parkinson's Disease), coordinated by the CETpD. The project's aim is to improve the quality of life of patients with Parkinson's disease.
