Healthy fat cells uncouple obesity from diabetes
About 422 million people around the world, including more than 30 million Americans, have diabetes. Approximately ninety percent of them have type 2 diabetes. People with this condition cannot effectively use insulin, a hormone made by the pancreas that helps the body turn blood sugar (glucose) into energy.

Ethiopian 7-year trial finds that childhood eye infection increases after antibiotic program ends
Continuous mass distribution of azithromycin in northern Ethiopia, where the childhood eye infection trachoma is a major cause of blindness, is effective in preventing recurrence of trachoma but does not eliminate the infection entirely, according to a new study in PLOS Medicine by Jeremy Keenan and colleagues from the University of California in San Francisco, USA and the Carter Center in Addis Ababa, Ethiopia and Georgia, USA.

Deaths from resident-to-resident incidents in dementia offers insights to inform policy
Analyzing the incidents between residents in dementia in long-term care homes may hold the key to reducing future fatalities among this vulnerable population, according to new research from the University of Minnesota School of Nursing. Gathered from media accounts and death review records, the exploratory study by Eilon Caspi, Ph.D., is the first to examine the circumstances surrounding the death of elders as a result of resident-to-resident incidents in dementia in the United States and Canada.

Clinical trial suggests new direction for heavy-smoking head and neck cancer patients
Patients with a greater than 10 pack/year history of smoking tend to develop an especially dangerous form of head and neck squamous cell cancer (HNSCC) for which prognosis remains poor and treatments have changed little during the past two decades. However, recent phase 1 clinical trial results by the Head and Neck Cancer Group at University of Colorado Cancer Center suggest a possible new direction for these patients. The first-in-human trial of the oral PARP inhibitor olaparib, with the anti-EGFR drug cetuximab and radiation, led to 72 percent 2-year survival in 16 patients on trial, compared with an expected 2-year survival rate of about 55 percent for standard-of-care treatment.

Study shows how MERS coronavirus evolves to infect different species
In the past 15 years, two outbreaks of severe respiratory disease were caused by coronaviruses transmitted from animals to humans. In 2003, SARS-CoV (severe acute respiratory syndrome coronavirus) spread from civets to infect more than 8,000 people, leading to a year-long global public health emergency. MERS-CoV (Middle East respiratory syndrome coronavirus), first identified in 2012, consistently jumps from dromedary camels to people, resulting in periodic outbreaks with a roughly 35 percent fatality rate. Evidence suggests that both viruses originated in bats before transmitting to civets and camels, respectively. While many other coronaviruses in nature are not known to infect people, MERS-CoV and SARS-CoV are notable for their ability to infect a variety of different species, including humans.

Inching closer to a soft spot in isoniazid-resistant tuberculosis
Antibiotic-resistant tuberculosis is a public health threat. TB and other bacteria become resistant to antibiotics by evolving genetic changes over time, which they can do quite quickly because bacterial lifecycles are short. In fact, it takes only a single genetic mutation to grant TB resistance to isoniazid, one of the first-line antibiotics.

Study: What patients really think about opioid vs non-opioid medications for chronic pain
Prescriptions of opioids for chronic pain has increased dramatically since the 1990s in spite of their known harms. Despite a shortage of scientific studies on the long-term effectiveness of opioids such as morphine, oxycodone and hydrocodone, they are frequently perceived to be stronger, more powerful pain relievers than non-opioid alternatives like acetaminophen or ibuprofen.

Research identifies potential guidance for gastric cancer treatment
Researchers from Wake Forest Baptist Medical Center and Tianjin Medical University Cancer Institute and Hospital (TMUCIH) have discovered that gastric cancer tissue samples bearing mutation of a specific gene, MUC16, too are associated with higher tumor mutation loads. Also known as tumor mutation burdens, measurement of high genetic mutation rates among cancerous versus healthy tissue has increasingly been shown to correlate with effective response rates to immunotherapy. The knowledge could bode positively for patients with the biomarker present.
