Untreatable gonorrhoea on the rise worldwide

Untreatable gonorrhoea on the rise worldwide | Salud Publica | Scoop.it

Gonorrhoea is becoming as incurable as it was in the 1920s, before the first drugs to treat it were discovered. More than 60% of countries surveyed around the world have reported cases that resist last-resort antibiotics, according to an announcement by the World Health Organization (WHO) on 6 July, 2017. The announcement included information about a new gonorrhoea drug in development.

 

Since the 1930s, several classes of antibiotics have been used to kill the bacterium that causes gonorrhoea, Neisseria gonorrhoeae. Widespread use — and misuse — of these drugs, however, has led to a rise of antibiotic-resistant strains of the bacteria. “The best time to have had gonorrhoea was the eighties, since there were many drugs to treat it with,” says Ramanan Laxminarayan, director of the Center for Disease Dynamics, Economics and Policy in Washington DC. Increasingly, that's no longer the case, he says.

 

Health agencies in the United States, Europe and Canada have in recent years flagged drug-resistant gonorrhoea as an emerging threat. If left untreated, gonorrhoea can increase a woman’s risk of developing HIV infection, infertility or ectopic pregnancy — among other effects. When the WHO partnered with the Drugs for Neglected Diseases initiative (DNDi), a non-governmental organization in Geneva, Switzerland, in May 2016 to confront antimicrobial resistance, gonorrhoea was at the top of the list.

UMMC Implants the Worlds Smallest Pacemaker

UMMC Implants the Worlds Smallest Pacemaker | Salud Publica | Scoop.it

The University of Maryland Medical Center’s Stephen Shorofsky, MD, PhD, was one of the first doctors in Maryland to implant the world’s smallest pacemaker for patients with bradycardia.

 

Recently approved by the U.S. Food and Drug Administration (FDA), the Micra® Transcatheter Pacing System (TPS) is a new type of heart device that provides patients with the most advanced pacing technology at one-tenth the size of a traditional pacemaker.

 

Micra is the only leadless pacemaker approved for use in the U.S. Bradycardia is a condition characterized by a slow or irregular heart rhythm. As a result, the heart is unable to pump enough oxygen-rich blood to the body during normal activity or exercise, causing dizziness, fatigue, shortness of breath or fainting spells. Pacemakers are the most common way to treat bradycardia to help restore the heart's normal rhythm and relieve symptoms by sending electrical impulses to the heart to increase the heart rate.

 

Comparable in size to a large vitamin, physicians at UMMC have elected to use the Medtronic Micra TPS because unlike traditional pacemakers, the device does not require cardiac wires (leads) or a surgical “pocket” under the skin to deliver a pacing therapy. Instead, the device is small enough to be delivered through a catheter and implanted directly into the heart with small tines, providing a safe alternative to conventional pacemakers without the complications associated with leads – all while being cosmetically invisible. The Micra TPS is also designed to automatically adjust pacing therapy based on a patient’s activity levels.

Projecting a visual image directly into the brain, bypassing the eyes

Projecting a visual image directly into the brain, bypassing the eyes | Salud Publica | Scoop.it
Imagine replacing a damaged eye with a window directly into the brain — one that communicates with the visual part of the cerebral cortex by reading from a million individual neurons and simultaneously stimulating 1,000 of them with single-cell accuracy, allowing someone to see again.

That’s the goal of a $21.6 million DARPA award to the University of California, Berkeley (UC Berkeley), one of six organizations funded by DARPA’s Neural Engineering System Design program announced this week to develop implantable, biocompatible neural interfaces that can compensate for visual or hearing deficits.*

The UCB researchers ultimately hope to build a device for use in humans. But the researchers’ goal during the four-year funding period is more modest: to create a prototype to read and write to the brains of model organisms — allowing for neural activity and behavior to be monitored and controlled simultaneously. These organisms include zebrafish larvae, which are transparent, and mice, via a transparent window in the skull.

 

“The ability to talk to the brain has the incredible potential to help compensate for neurological damage caused by degenerative diseases or injury,” said project leader Ehud Isacoff, a UC Berkeley professor of molecular and cell biology and director of the Helen Wills Neuroscience Institute. “By encoding perceptions into the human cortex, you could allow the blind to see or the paralyzed to feel touch.”

 

To communicate with the brain, the team will first insert a gene into neurons that makes fluorescent proteins, which flash when a cell fires an action potential. This will be accompanied by a second gene that makes a light-activated “optogenetic” protein, which stimulates neurons in response to a pulse of light.

 

To read, the team is developing a miniaturized “light field microscope.” Mounted on a small window in the skull, it peers through the surface of the brain to visualize up to a million neurons at a time at different depths and monitor their activity. This microscope is based on the revolutionary “light field camera,” which captures light through an array of lenses and reconstructs images computationally in any focus.

 

The combined read-write function will eventually be used to directly encode perceptions into the human cortex — inputting a visual scene to enable a blind person to see. The goal is to eventually enable physicians to monitor and activate thousands to millions of individual human neurons using light.

 

Isacoff, who specializes in using optogenetics to study the brain’s architecture, can already successfully read from thousands of neurons in the brain of a larval zebrafish, using a large microscope that peers through the transparent skin of an immobilized fish, and simultaneously write to a similar number.

 

The team will also develop computational methods that identify the brain activity patterns associated with different sensory experiences, hoping to learn the rules well enough to generate “synthetic percepts” — meaning visual images representing things being touched — by a person with a missing hand, for example. This technology has a lot of potential in the future.

Human liver cells seeded in mouse expands 50-fold to functional organoid

Human liver cells seeded in mouse expands 50-fold to functional organoid | Salud Publica | Scoop.it

Scientists worked out the cellular assembly for seeding a whole new organ. To grow a liver, researchers led by MIT engineer Sangeeta Bhatia started by carefully designing a cellular scaffold for the organ to grow on. They first got human liver cells (hepatocytes) and connective tissue cells (fibroblasts) to grow together in clumps. Then they used a micro-tissue molding to create ropes endothelial cells, which make up the lining of blood and lymphatic vessels. Last, they carefully assembled rows of the cell clumps in between strands of endothelial chords and held the structure together with a biodegradable hydrogel.

 

In all, they called the organ starter kit SEED, for “In Situ Expansion of Engineered Devices.” To test out the SEEDs, the researchers implanted them into the belly fat of healthy mice and mice with a genetic disorder that causes liver damage.  In the healthy mice, the liver seeds didn’t grow very much. But in the rodents with liver damage—which were circulating liver-regenerating growth factors and other molecular signals to repair their damaged liver—the organ SEEDs sprouted.

 

Eighty days after implantation, there was a 50-fold cellular expansion along the SEED’s scaffold. The liver organoid formed precursor bile ducts and contained clusters of red blood cells, suggesting vasculature formation. The organoid also pumped out standard human liver proteins, including albumin and transferrin.

 

There’s a lot more work to go before researchers have a human-sized, functional liver, but the team is optimistic. “We believe that this work sets the stage for using SEEDs as an alternative strategy for scale-up of engineered organs, one that uses native developmental, injury, or regenerative signals to expand prefabricated constructs in situ,” they conclude.
