New paper: paralyzed man uses thoughts to control robotic arm

Excerpt:

Researchers at the University of Pittsburgh School of Medicine and UPMC describe in PLoS ONE how an electrode array sitting on top of the brain enabled a 30-year-old paralyzed man to control the movement of a character on a computer screen in three dimensions with just his thoughts. It also enabled him to move a robot arm to touch a friend’s hand for the first time in the seven years since he was injured in a motorcycle accident.

With brain-computer interface (BCI) technology, the thoughts of Tim Hemmes, who sustained a spinal cord injury that left him unable to move his body below the shoulders, were interpreted by computer algorithms and translated into intended movement of a computer cursor and, later, a robot arm, explained lead investigator Wei Wang, Ph.D., assistant professor, Department of Physical Medicine and Rehabilitation, Pitt School of Medicine.

“When Tim reached out to high-five me with the robotic arm, we knew this technology had the potential to help people who cannot move their own arms achieve greater independence,” said Dr. Wang, reflecting on a memorable scene from September 2011 that was re-told in stories around the world. “It’s very important that we continue this effort to fulfill the promise we saw that day.”

Six weeks before the implantation surgery, the team conducted functional magnetic resonance imaging (fMRI) of Mr. Hemmes’ brain while he watched videos of arm movement. They used that information to place a postage stamp-size electrocortigraphy (ECoG) grid of 28 recording electrodes on the surface of the brain region that fMRI showed controlled right arm and hand movement. Wires from the device were tunneled under the skin of his neck to emerge from his chest where they could be connected to computer cables as necessary.

For 12 days at his home and nine days in the research lab, Mr. Hemmes began the testing protocol by watching a virtual arm move, which triggered neural signals that were sensed by the electrodes. Distinct signal patterns for particular observed movements were used to guide the up and down motion of a ball on a computer screen. Soon after mastering movement of the ball in two dimensions, namely up/down and right/left, he was able to also move it in/out with accuracy on a 3-dimensional display.

“During the learning process, the computer helped Tim hit his target smoothly by restricting how far off course the ball could wander,” Dr. Wang said. “We gradually took off the ‘training wheels,’ as we called it, and he was soon doing the tasks by himself with 100 percent brain control.”

I think that this is relevant to the physicalism vs immaterial mind/soul debate. Here’s a person using mental effort to control matter.

Report: Patients receiving poor care at NHS hospital

4 Comments

A damning report on the state of government-run health care in the UK, found in the leftist New York Times, of all places.

Excerpt:

Shockingly bad care and inhumane treatment at a hospital in the Midlands led to hundreds of unnecessary deaths and stripped countless patients of their dignity and self-respect, according to a scathing report published on Wednesday.

The report, which examined conditions at Stafford Hospital in Staffordshire over a 50-month period between 2005 and 2009, cites example after example of horrific treatment: patients left unbathed and lying in their own urine and excrement; patients left so thirsty that they drank water from vases; patients denied medication, pain relief and food by callous and overworked staff members; patients who contracted infections due to filthy conditions; and patients sent home to die after being given the wrong diagnoses.

[…]The report into what has been called the biggest scandal in the modern history of the health service found that many of the problems were due to the efforts of the hospital to meet health-service targets, like providing care within four hours to patients arriving at the emergency room. It also said that in its efforts to balance its books and save $16 million in 2006 and 2007 in order to achieve so-called foundation-trust status, which made it semi-independent of control by the central government, the hospital laid off too many people and focused relentlessly on external objectives rather than patient care.

Patients have to be cared about in a for-profit system, otherwise, no one will get paid. In a socialist system, patients pay first and then hope to get care later. Although there are many hard-working doctors and nurses in the NHS, you can’t separate the care that a patient gets from the reward that doctors and nurses get, otherwise, they lose their incentive to care for patients.

But an even bigger problem is that when government runs health care, all kinds of things start to get covered that are not really health care, as the government begins to use health care as a way to buy votes. Suddenly, patients with real health care needs have to get in line behind people who want sex changes, breast implants, IVF, elective abortions and so on. There just isn’t time to give everyone care when the people seeking have no incentive to live responsible lives and make responsible choices in order to avoid risks that may require care. I do believe that the majority of NHS doctors and nurses mean well. They want to serve and help others. But when patients have no incentive to be responsible, there will be too much demand for care, and there will be shortages. When prices are health below market value, demand surges and a shortage will occur.

Here’s a bit more about the NHS health care problem from the UK Daily Mail.

Excerpt:

This week, the  scathing report on the Stafford Hospital  Scandal — after abuse and neglect led to the unnecessary deaths of hundreds of patients — said ‘fundamental change’ was needed in the NHS. It condemned ‘failings at every level’ and contained 290 recommendations for reform. However, Robert Francis QC’s report was merely the latest damning indictment of the health service.

In November 2012 the Care Quality Commission found that ten per cent of hospitals and  15 per cent of care homes weren’t treating their patients with respect. Health Secretary, Jeremy Hunt, warned that cruelty and neglect  had become normal in some hospitals and care homes.

[…]Reports in 2011 from Age UK and The Patients’ Association exposed some horrendous instances of abuse and neglect — not only enforced incontinence and unanswered buzzers, but patients left hungry and thirsty or in soiled bed-linen.

Another reason for these shortages is bureaucratic red tape. Government-run enterprises are inefficient:

Talking with a cross-section of hospital staff, older nurses told me where they feel the problems lie. They say it is not so much a question of cruelty and neglect — although they acknowledge that this can exist — but more that ward culture has changed.

In the past, the patient’s comfort and needs came first, but now it is all too easy for elements of patient care to be missed as nursing staff focus on paperwork and meeting targets.

Should we have government-run health care? Let’s look at how it works in other countries and decide using the evidence.

Government-run health care: starving sick babies and children to death

1 Comment

Here’s a scary story from the UK Daily Mail. (H/T Dan Mitchell)

Excerpt:

Now sick babies go on death pathway: Doctor’s haunting testimony reveals how children are put on end-of-life plan

  • Practice of withdrawing food and fluid by tube being used on young patients
  • Doctor admits starving and dehydrating ten babies to death in neonatal unit
  • Liverpool Care Pathway subject of independent inquiry ordered by ministers
  • Investigation, including child patients, will look at whether cash payments to hospitals to hit death pathway targets have influenced doctors’ decisions

Sick children are being discharged from NHS hospitals to die at home or in hospices on controversial ‘death pathways’.

Until now, end of life regime the Liverpool Care Pathway was thought to have involved only elderly and terminally-ill adults.

But the Mail can reveal the practice of withdrawing food and fluid by tube is being used on young patients as well as severely disabled newborn babies.

One doctor has admitted starving and dehydrating ten babies to death in the neonatal unit of one hospital alone.

Writing in a leading medical journal, the physician revealed the process can take an average of ten days during which a  baby becomes ‘smaller and shrunken’.

The LCP – on which 130,000 elderly and terminally-ill adult patients die each year – is now the subject of an independent inquiry ordered by ministers.

The investigation, which will include child patients, will look at whether cash payments to hospitals to hit death pathway targets have influenced doctors’ decisions.

Read the whole thing, but here’s a snip:

Bernadette Lloyd, a hospice paediatric nurse, has written to the Cabinet Office and the Department of Health to criticise the use of death pathways for children.

She said: ‘The parents feel coerced, at a very traumatic time, into agreeing that this is correct for their child whom they are told by doctors has only has a few days to live. It is very difficult to predict death. I have seen a “reasonable” number of children recover after being taken off the pathway.

‘I have also seen children die in terrible thirst because fluids are withdrawn from them until they die.

‘I witnessed a 14 year-old boy with cancer die with his tongue stuck to the roof of his mouth when doctors refused to give him liquids by tube. His death was agonising for him, and for us nurses to watch. This is euthanasia by the backdoor.’

This is what Democrats believe about health care. When the government runs health care, health stops being about curing sickness and starts being about buying votes. Suddenly, free abortions, breast enlargements, in vitro fertilization, drugs to calm down fatherless children, contraception, HIV/AIDS all become priorities. There are some people out there who want government to pay for the health effects of their own immoral / reckless choices, and that’s what government-run health care is really about. Enabling certain lifestyles that require health care subsidies so those people can live “as good as” traditional morality lifestyles. It’s interesting to note that in countries that have government-run health care, like Canada, doctors and nurses are regularly forced to act against their consciences to murder rather than cure. It’s no surprise because socialists in the Soviet Union and Nazi Germany have essentially the same view of conscience as modern leftists like the Democrat Party.

There isn’t enough money for us to pay people to voluntarily incur health care costs (and other social costs) with their immoral / irresponsible choices. But that’s exactly what happens when you make everything “health care” and then make it “free” in order to buy votes from people like Sandra Fluke. What Democrats do is look for groups that need subsidies or validation and they offer it to them with taxpayer money and laws prohibiting dissent. They essentially take the complete anti-freedom point of view on every question. They hate liberty, and love power. The want to control others and to be adored by those who depend on their benevolent redistribution of other people’s money.
