Drug-checking programs should therefore be expanded, argue the researchers.

New study offers hope for patients suffering from a rare form of blindness

A new form of therapy may halt or even reverse a form of progressive vision loss that, until now, has inevitably led to blindness. This hyper-targeted approach offers hope to individuals living with spinocerebellar ataxia type 7 (SCA7) and validates a new form of therapy with the potential to treat neurogenetic diseases effectively and with far fewer side effects than other medications. Details of this therapy appear in the latest issue of Science Translational Medicine.

Specific CD8 T cell states may indicate response to immune checkpoint therapy for melanoma

A multi-institutional research team, led by investigators at Massachusetts General Hospital (MGH) and the Broad Institute of MIT and Harvard, has identified specific states of cytotoxic CD8 T cells that are associated with patient response to checkpoint immunotherapy for melanoma. Their report published in the journal Cell also identifies specific marker proteins associated with these cell states, providing data that could help better understand why checkpoint therapy—which enables the immune system to attack cancerous tumors—doesn't work for all patients and may enable the development of tests to help predict which patients may be helped by the approach. A companion immunotherapy study, led by a separate research team from the Broad Institute and Dana-Farber Cancer Institute, appears in the same issue of Cell.

Drug combination for treatment-resistant depression not more effective than a single antidepressant

Psychiatrists and GPs increasingly combine mirtazapine with an SSRI (selective serotonin reuptake inhibitor) or SNRI (serotonin-noradenaline reuptake inhibitor) antidepressant for patients whose depression does not respond to a single antidepressant. A large clinical trial led by researchers at the Universities of Bristol, Exeter, Keele, Manchester and Hull York Medical School, and published in the British Medical Journal today, looked at the effectiveness of adding mirtazapine to an SSRI or SNRI in patients who remain depressed after at least six weeks of conventional (SSRI or SNRI) antidepressant treatment. They found that this combination was no more effective in improving depression than placebo and call on doctors to rethink its use.

Custom weight-based safety system to protect embryos and eggs against cryogenic storage failure

Earlier this year, more than 4,000 eggs and embryos were inadvertently lost as a result of cryogenic tank failures at two fertility centers. Today, Columbia University Fertility Center announced it has developed and built the first weight-based scale safety system to protect stored eggs and embryos in response to these reported failures. Through its custom, web-enabled safety system, Columbia University Fertility can now continuously monitor the real-time weights of its storage tanks and can detect impending tank failures sooner. As a result, it reduces the risk of any damage to embryos and eggs by greatly increasing the time available to intervene should an issue arise. Columbia University Fertility Center is the first and only fertility center to offer this additional layer of protection in its clinic.

Dolutegravir, an alternative first-line HIV treatment for low and middle-income countries

The latest World Health Organization (WHO) recommendations published in July 2018 advocate first-line treatment of HIV infection using dolutegravir (DTG) as an alternative to treatment with efavirenz at 400 mg (EFV400). Until now, no clinical trial data have been collected for direct comparison of the efficacy of the two drugs in the specific context of low-income countries. The ANRS NAMSAL study has compared the effect of both DTG and EFV with 613 participants living with HIV who had not previously received ARV treatment.

RNA defects linked to multiple myeloma progression in high risk patients

Multiple myeloma (MM) is the second most common type of blood cancer where cancer cells accumulate in the bone marrow, crowding out healthy blood cells. Studies on MM development have traditionally focused mostly on DNA abnormalities, but a team of researchers from the Cancer Institute of Singapore (CSI Singapore) at the National University of Singapore has uncovered an association between RNA abnormalities and MM progression. In particular, the team discovered that overexpression of ADAR1, a RNA-editing enzyme, and a modified gene caused by irregular RNA editing are key to MM progression and the development of resistance to current treatments.

The findings are published in the journal Nicotine and Tobacco Research.

We all want 'healthy aging,' but what is it, really? New report looks for answers

"Healthy aging" sounds like a priority we all can share, but for geriatrics healthcare professionals—the doctors, nurses, pharmacists, physicians assistants, social workers, and many others dedicated to the care we need as we age—that term represents something specific, and something worth defining. Led by Paul Mulhausen, MD, MHS, FACP, AGSF, colleagues from the American Geriatrics Society (AGS) set about doing just that as part of an expert panel convened to look critically at what "healthy aging" really means. Their definition—published in a white paper today in the Journal of the American Geriatrics Society —explores the intersection between our personal care goals and innovations in science, education, and public policy as the place where healthy aging may be understood best.

To ward off fatty liver, breast is best for mom

Researchers at University of California San Diego School of Medicine and Kaiser Permanente have discovered that mothers who breastfed a child or children for six months or more are at lower risk for developing non-alcoholic fatty liver disease (NAFLD) years later during mid-life.

New study to decode what makes people immune to influenza

The key to lasting protection against influenza may be in your bones. The cells that naturally protect you against illness originate and live in your bone marrow—and that is one spot where scientists will be looking to understand the human immune system's response to influenza in a groundbreaking new study led by the Human Vaccines Project. The goal is to harness an understanding of the immune system to develop longer lasting protection against the flu.

Women carrying rare breast cancer variants more likely to develop interval breast cancers

While the presence of common breast cancer mutations was indicative of increased breast cancer risk, the presence of certain rare mutations was indicative of increased risk from interval breast cancers and death.

Insurance-related disparities in timely access to gold standard dialysis procedure

Patients with newly diagnosed kidney failure must wait for up to 3 months before they qualify for Medicare. A new study found that this short period of time without insurance is associated with delays in the placement and use of preferred methods for gaining access to the bloodstream for dialysis. The study, which appears in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN), also found that this insurance lag time is linked with a higher risk of later dialysis-related infection.

Long trip: Psychedelic advocate nears goal of legal ecstasy

Growing up amid the tumult of the Cuban Missile Crisis and the Vietnam War, Rick Doblin says he became convinced that humanity was "crazy" and "inherently destructive." As a teenager, he came to see the mind-expanding effects of psychedelics—including LSD and magic mushrooms—as the antidote to mankind's inner demons.

Supply chain transparency needed to combat soaring insulin costs

Updated European guidance for the diagnosis and management of osteoporosis in women

The clinical significance of osteoporosis lies in the painful, debilitating fractures that arise, which are a major cause of long-term disability in the population. Nevertheless, osteoporosis is under-diagnosed and undertreated: in the European Union, it is estimated that 57 % of women at high risk of fragility fracture due to osteoporosis do not receive bone-specific treatment. In patients with fragility fractures, less than 20 % receive treatment to reduce the chance of a future fracture.

Fatal measles case highlights importance of herd immunity in protecting the vulnerable

Last year, a 26-year-old man receiving treatment for leukemia went to a Swiss hospital's emergency room with a fever, a sore throat, and a cough, and was admitted. His condition worsened, and 17 days later, he died from severe complications of measles. The man's weakened immune system was unable to fight off the disease, even though he was vaccinated against measles as a child.

How invading jumping genes are thwarted

Since Carnegie Institution's Barbara McClintock received her Nobel Prize on her discovery of jumping genes in 1983, we have learned that almost half of our DNA is made up of jumping genes—called transposons. Given their ability of jumping around the genome in developing sperm and egg cells, their invasion triggers DNA damage and mutations. This often leads to animal sterility or even death, threatening species survival. The high abundance of jumping genes implies that organisms have survived millions, if not billions, of transposon invasions. However, little is known about where this adaptability comes from. Now, a team of Carnegie researchers has discovered that, upon jumping gene invasion, reproductive stem cells boost production of non-coding RNA elements (piRNA) that suppress their activity and activates a DNA repair process allowing for normal egg development. The results are published in the November 1, 2018, issue of Developmental Cell.

Yangtze dams put endangered sturgeon's future in doubt

Before the damming of the Yangtze River in 1981, Chinese sturgeon swam freely each summer one after another into the river's mouth, continuing upriver while fasting all along the way. They bred in the upper spawning ground the following fall before returning quickly back to the sea. Now, researchers reporting in Current Biology on November 1 offer new insight into the threat the dams have since posed to the critically endangered fish.

How cancer-causing papillomaviruses evolved

Cancer-causing human papillomaviruses (HPVs) diverged from their most recent common ancestors approximately half a million years ago, roughly coinciding with the timing of the split between archaic Neanderthals and modern Homo sapiens, according to a study published November 1 in the open-access journal PLOS Pathogens by Zigui Chen of the Chinese University of Hong Kong, Robert Burk of the Albert Einstein College of Medicine, and colleagues.

Searching in soil, scientists find a new way to combat tuberculosis

For decades, doctors have been using antibiotics to fight tuberculosis (TB). And consistently, the microbe responsible for the disease, Mycobacterium tuberculosis, has been fighting back. When confronted with current drugs, such as the antibiotic rifamycin, the bacterium often mutates in ways that make it resistant to the treatment.

Perilous times for Australia wildlife amid severe drought

From abandoned baby kangaroos to wallabies being blinded by the sun and koalas having to go walkabout to look for eucalyptus leaves, Australia's exotic wild animals are struggling to adapt to a crippling drought.

Trading sex for sleep—aging dormice shorten their hibernation for more reproduction

Edible dormice are extremely long-lived for their size, thanks to their seasonal dormancy. The animals are veritable record holders in longevity, with hibernation periods lasting between at least six and a maximum of 11 months. The factors influencing the variable duration of the hibernation period, apart from the specific environmental conditions, have so far been unknown. Researchers at Vetmeduni Vienna hypothesised that older animals should shorten their winter dormancy in favour of a reproductive advantage. This hypothesis has now been confirmed in a database analysis, published in Scientific Reports, of dormice populations living in large outdoor enclosures. The shortened winter hibernation of aging males and females were due to an increase in reproductive activity. Older animals also delay the onset of hibernation and emerge earlier in the season.

Photos in social media reveal socio-cultural value of landscapes

Every day, users upload millions of photos on platforms such as Flickr, Instagram and Facebook. A study by researchers of Karlsruhe Institute of Technology (KIT) now shows that these photos can be used to assess the social importance of certain landscapes. For this purpose, they developed a new image analysis method based on artificial intelligence. The results might be of particular importance for landscape management and presentation. The results are published in the journal Ecological Indicators.

Giraffes: Equals stick together

In 2016, virtually overnight, one giraffe species turned into four. Using new, even more extensive genetic tests, Senckenberg scientists have now been able to show that the four giraffe populations identified as separate species practically never interbreed, even where they occur in close vicinity to each other. The negligible number of hybrids serves as additional evidence that the Southern, Masai, Reticulated, and Northern Giraffes in fact constitute four separate species, according to the team's study, published as the title story in the recent edition of Ecology and Evolution. Conservation measures in accordance with these findings are therefore urgently needed.

How sheep grazing affects the Norwegian mountains

When animals graze, they affect the environment. They keep meadows open, their faeces fertilizes the soil, and forests yield to cultivated landscapes. But what effect does grazing have on overall biomass? Does grazing affect carbon capture, too? How many plants survive and what kind?

Plants rely on their resident bacteria to protect them from harmful microbes

Fungi and other filamentous microbes called oomycetes cause many devastating plant diseases and are together responsible for more than 10 percent of all crop loss. A groundbreaking new study now shows that even healthy plants host potentially harmful fungi and oomycetes in plant roots. That they do not succumb to illness is due to the simultaneous presence of a wide range of co-residing bacteria, which regulate the balance among these microorganisms in plant roots and thus ensure plant survival in nature. These are the conclusions of a study published in the journal Cell that was led by Stephane Hacquard and Paul Schulze-Lefert at the Max Planck Institute for Plant Breeding Research in Cologne, Germany.

Launch of global effort to read genetic code of all complex life on earth
