Hmmm;

Researchers are testing mild electrical stimulation to improve brain function and mental health, but warn do-it-yourselfers to be wary of treating themselves with models available online.

Dr. Fidel Vila-Rodriguez, director of the Non-Invasive Neurostimulation Therapies (NINET) Lab at the University of B.C., is starting to lend devices for home use to people with Parkinson’s disease and depression that will deliver a weak electrical current through electrodes placed on their temples.

Despite all our advances in cancer research, our best strategy of fighting the disease is still brute force, with only a fraction of the drugs administered actually reaching the tumour cells, and most being absorbed into healthy tissue. When cancer spreads, the likelihood of medication reaching it gets even lower, which is why secondary, or metastatic, tumours can be so deadly.

But now, researchers have used cancer’s own tricks against it, by developing dissolvable nanoparticles that target the heart of metastatic tumours directly. And they’ve already seen unprecedented success in mouse studies, with 40–50 percent of the animals being “functionally cured”, and tumour-free after eight months — the equivalent of about 24 years for a human patient. The team is so excited by these results, they hope to fast-track the research and begin human trails in 2017.

“I would never want to overpromise to the thousands of cancer patients looking for a cure, but the data is astounding,” said one of the researchers, Mauro Ferrari, from the Houston Methodist Research Institute. “We’re talking about changing the landscape of curing metastatic disease, so it’s no longer a death sentence.”

The toughest thing about HIV is the fact that it can mutate and hide and pretend to be a healthy cell. This is what makes it hard to cure HIV or AIDS. However there has been progress in Temple University as their researchers were able to find a way to eradicate HIV-1 from the body through gene-snipping.

“We don’t yet understand the mechanisms involved — it could be an increased inflammatory response, direct brain modulation by the parasite, or even reverse causation where aggressive individuals tend to have more cats or eat more undercooked meat”.

The study looked at 358 adults, and found that chronic latent infection with T. gondii is associated with intermittent explosive disorder and increased aggression. Antibodies were collected between 1991 and 2008.

University of Chicago researchers say a parasite commonly spread from cats to humans may play a role in impulsive aggression. Approximately 16 percent of those in a “other psychiatric conditions” organisation had a infection, though reported identical exam scores in charge to a healthy group.

One of the things I love most about being a Surgical Oncologist is that I see my patients for years after I have treated them. However, my clinic days are inevitably like the opening scenes from the old Wide World of Sports television program that aired on Saturday afternoons on ABC. I remember watching this show on weekends as a child and teenager. The “thrill of victory”, with images of athletes crossing the finish line in first place, equates to those patients who receive good news during their clinic visit. I tell them I am confident I can perform an operation to remove their cancer; or I confirm that their blood tests and scans show that tumors have not recurred after surgery, chemotherapy, and other treatments; or we pass some major chronologic milestone without evidence of cancer rearing its ugly head again (many patients still believe the 5 year anniversary of being cancer-free equates with being “cured”, if only that were always true). In contrast, the “agony of defeat”, forever seared in my memory in the opening scenes of Wide World of Sports with the ski jumper falling off the end of the jump and bouncing hard off the slope, represents the distress and depression felt by patients and their family members when I deliver bad news.

I would never make it as a professional poker player because I can’t bluff when I’m holding a bad hand or keep from grinning when I have a good one. My patients can tell from my face when I walk into the clinic room what the news is going to be. When all of the blood tests and scans reveal no evidence of cancer recurrence, I walk in smiling and immediately tell all gathered in the room that everything looks great and I see no evidence of any cancer. The remainder of the visit becomes a combination of medical checkup and social enterprise. I inquire about the well-being of their children, grandchildren, parents, other friends and relatives I have met, their pets, their gardening, their recent travels, and sundry snippets of their ongoing lives. Patients frequently bring pictures of children and grandchildren, or travel photos of places they have been since their last visit with me. Often I’m asked for medical advice on conditions totally unrelated to their cancers as they get farther and farther away from that diagnosis. My patients also know about tidbits from my life. They ask about the status of soccer teams that I coached, how my son or daughter were doing in college (both graduated and onto successful careers, thank you), and whether I have progressed from owning a Ferrari lanyard to hold and display my medical badge (I’m a fan of Ferrari F1 racing) to actually owning a Ferrari automobile (I do not).

I am told by patients, family members, and members of my patient care team that I am quite solemn when I walk in a clinic room to deliver bad news. No “light-hearted” chatter or discussion of recent family events or outings occurs. The nervous, hopeful smiles on the faces of the patient and the family members in the room quickly fade as I describe what I am seeing on their blood tests and the scans I have reviewed. Friedrich Nietzsche, the pejorative poster boy of pessimism, is credited with the aphorism, “Hope is the worst of evils, for it prolongs the torments of man.” Thankfully, he was not involved in the care of patients with cancer or other chronic illnesses. A particular patient comes to mind when I remember the importance of dealing with both the highs and the lows of talking with cancer patients.

The patient in question was the wife of an Emeritus Professor of Engineering at a prestigious American university. The Professor knew a thing or two about scientific investigation, statistics, and assessments of probability. Mrs. Professor had a large, grapefruit-sized malignant vascular tumor in the center of her liver called an epithelioid hemangioendothelioma. Quite a mouthful of a name for a rare malignant tumor of the liver. Her tumor was in an unfortunate location in the center of the liver and was wrapped around two of the three veins that drain all of the blood out of the liver into a large blood vessel called the inferior vena cava. The tumor was abutting a portion of the third vein. As a hepatobiliary surgical oncologist, I know I must preserve at least one of these veins to allow blood that flows into the liver to flow back out properly. She had seen surgeons at several other hospitals in the United States and was told that the tumor was inoperable and untreatable. If she was lucky, she might live a year, these doctors told my patient and her husband. The Professor contacted me, and I examined Mrs. Professor and evaluated her prior scans, and then obtained some additional high resolution scans to better understand the appearance of her tumor. I realized that her particular tumor had a very thick fibrous capsule surrounding it. I explained to the patient and her husband that it may be possible to remove the tumor, but that it would be challenging. This lady who had been sullen, withdrawn, and tearful every time I had met with them previously suddenly looked up and said, “If there’s any chance, I’m willing to take it!” I preceded the next week to perform an operation that removed the entire left lobe and a portion of the right lobe of her liver and I was able to gently dissect the tumor capsule free from the third hepatic vein. The operation was successful and the patient recovered well over the next several weeks.

Clarius Mobile Health, a firm based outside of Vancouver, Canada, is unveiling a wireless ultrasound transducer that uses your Android or Apple iPhone as the display and control system. There aren’t many details provided by Clarius about the product, but the company expects these ultrasounds to be used for procedures such as nerve blocks and for helping to deliver needle injections. The device has yet to receive clearance from the world’s regulatory bodies.

Check out the preview video for the Clarius mobile ultrasound:

It sounds really obvious, but hospitals aren’t for healthy people. The world’s entire health system is really there to react once people get ill. If doctors are able to catch an illness at stage one that’s great, but if it reaches stage three or four there’s often not that much that can be done. So what if we could treat patients at stage zero and predict the likelihood of contracting diseases? We could then get treatment to people who need it much earlier and take preventative steps to avoid illness altogether.

Currently, when we think of monitoring in healthcare we’re usually referring to monitoring patients’ reactions to drugs or treatments, but this is changing. No amateur runner’s uniform is complete these days without a Fitbit or some kind of analytics tool to monitor progress, so the idea of monitoring the healthy is becoming ingrained in the public’s consciousness. But Fitbits only scrape the surface of what we can do. What if the data from fitness trackers could be combined with medical records, census data and the details of supermarket loyalty cards to predict the likelihood of contracting a particular disease?

With big data we can move from reacting to predicting, but how do we move beyond just making predictions; how do we prevent disease from occurring altogether? Up until now all of our monitoring technology has been located outside of the body, but nano-sized entities made of DNA could one day patrol the body, only acting when they come into contact with specific cells – cancer cells, for example. The technology that would turn tiny machines – roughly the size of a virus – into molecular delivery trucks that transport medication is already being worked on by bioengineers. If this kind of technology can be used to treat cancer, without needing to release toxic agents into the body, can the same technology be inserted into a healthy person and lie in wait for the opportunity to fight disease on its host’s behalf?

It seems counterintuitive, right? Rip out eight lanes of freeway through the middle of your metropolis and you’ll be rewarded with not only less traffic, but safer, more efficient cities? But it’s true, and it’s happening in places all over the world.

Many freeway systems were overbuilt in an auto-obsessed era, only to realize later that cities are actually healthier, greener, and safer without them. Like freeway cap parks, which hope to bridge the chasms through severed neighborhoods—Boston’s Big Dig is a great example—freeway removal projects try to eradicate and undo the damage wrought from highways, while creating new, multifunctional shared streets that can be utilized by transit, bikes, walkers and yes, even cars.
