With the 2014 Winter Paralympics set for March, Wikinews sought comment from U.S. Representative Jackie Speier, who serves California’s 14th congressional district about the event and how current U.S. policies impact people with disabilities. Elected to the U.S. House in 2008, she serves on the Committee on Oversight and Government Reform and the House Armed Services Committee. For the first time ever, the Paralympics will be broadcast live in the U.S. on network television.

((Wikinews)) : Will “Obamacare” have a positive or negative impact on the lives of people with disabilities?

Jackie Speier: By-and-large the Affordable Care Act will have a significant and lasting beneficial impact on persons with disabilities […] Most importantly, pre-existing conditions will no longer prevent persons with disabilities from obtaining health insurance. Lifetime limits on medical expenses will be removed and preventive services will be free. All of these provisions of the law create health insurance that is highly supportive of good health outcomes for everyone, but in particular for those who have a disability.

((WN)) : Are there any Paralympic athletes or elite athletes with disabilities from your district that people should know more about?

Jackie Speier: There are currently two Paralympic athletes who train or live in my district that people will definitely hear more about in the coming years. One is a young woman named Allie Hyatt who trains in Judo with Willy Cahill, [whom] I have also trained with. Allie, who is visually impaired and just 15, has already won numerous awards and will participate in the Youth Olympic Games next year. She is sure to be a force in the Judo world for many, many years. Hyatt lives in San Francisco and Cahill is the founder and CEO of the Blind Judo Foundation.

Another great athlete is Mohamend Lahna who is training for the Rio Olympics in 2016 for the paratriathlon,” Speier continued. “He is from Morocco originally but lives now in San Mateo and trains daily at the College of San Mateo. He runs marathons with a prosthetic leg and has his sights set on winning several medals atworld and Olympic events in the future. Lahna has proximal femoral focal deficiency (PFFD), a birth defect that affects the hip and pelvis. He is married and has a 1-year-old child.

Wikinews also sought comment from other members of Congress, including John K. Delaney, Mike Honda, Kyrsten Sinema, Eric Swalwell, Raúl M. Grijalva and Ann Kirkpatrick but at publication time, had received no response.

Even without LaDainian Tomlinson and Philip Rivers, the Chargers made sure the Indianapolis Colts won’t repeat as Super Bowl champions.

Now San Diego must make sure it doesn’t repeat its last performance at New England.

That will be especially difficult without an injured L.T., who departed in the first half with a bruised left knee, and starting quarterback Rivers, who went out in the third quarter with a damaged right knee in the Chargers’ stunning 28-24 victory Sunday.

With Billy Volek at quarterback and Michael Turner as the main runner, San Diego went 78 yards on eight plays, with Volek sneaking in from the 1 with 4:50 remaining for the lead. The Chargers’ big-play defense then held on downs at its 7, and stopped Indy again in the final moments to preserve their eighth straight win.

To make it nine in a row and advance to their second Super Bowl — the other was a loss to San Francisco after the 1994 season — the Chargers will need all the resourcefulness they showed at Indianapolis. Being undermanned against undefeated New England hardly is an enticing prospect.

Still, with All-Pro cornerback Antonio Cromartie getting an interception and fumble recovery, and linebackers Shawne Merriman and Shaun Phillips plaguing Peyton Manning, the Chargers showed they have the ability to throw off any offense. Maybe even the most prolific attack in NFL history.

The Chargers didn’t come close against the Patriots in Week 2, falling 38-14. That was the beginning of a slide to 5-5 for San Diego, but the Chargers (13-5) are rolling now.

It was a gutty showing by Rivers, who threw for three scores — he banged his right knee on a 56-yard screen pass TD by Darren Sproles to end the third quarter. And Turner, who could be a starter elsewhere but usually sits behind league rushing leader Tomlinson, gave the offense the balance it desperately needed in the late stages of the upset, rushing for 71 yards.

The Chargers’ opportunistic defense, which led the league in takeaways (48) and turnover margin (plus-24), grabbed two interceptions — both on tipped balls — and a fumble. While San Diego couldn’t stop Manning’s offense from steadily marching downfield most of the game, it could make the key plays that get you closer to the Super Bowl.

Still, if Tomlinson is limited or sidelined, how much chance do the Chargers have against the perfect Patriots? Not to mention perhaps missing Rivers or tight end Antonio Gates, who courageously played much of the day on a dislocated toe.

For the Colts (13-4), it was a bitterly quick elimination from the postseason.

A year ago, they won three playoff games, then beat Chicago in the Super Bowl. They couldn’t recapture their touch on offense or defense this time, and a defense that allowed the fewest points during the season wore down against the equally physical Chargers.

Manning did throw for 402 yards, completing 33 of his 48 throws, but both interceptions killed deep scoring threats.

Rivers was 14-of-19 for 264 yards, and Volek went 3-of-4 for 48 yards in his clutch relief role. Vincent Jackson became Rivers’ top target and had seven catches for 93 yards and a score.

Aylesbury, England — The Arsenal F.C. midfielder Jermaine Pennant, currently on loan to Birmingham City, has today pleaded guilty to drink-driving, driving while disqualified, and driving without insurance by Aylesbury magistrates court. Pennant received a sentence of three months imprisonment. Pennant’s lawyer, Bary Warbutton, has said that the footballer will appeal against the severity of the sentence.

The incident occurred on January 23 of this year, Pennant was arrested after crashing teammate Ashley Cole’s car into a lamppost. The 22-year-old claimed that he crashed the car after attempting to operate the car’s Satellite navigation system.

Despite the claim by Warbutton that imprisonment “could completely destroy his career”, Birmingham City have said that they will stand by the player, and help to rehabilitate him. Arsenal released a statement saying that the sentence would not impact the player’s future with the club; his contract with club expires in the summer, at the same time as his loan-spell with Birmingham ends.

In findings published on Monday in Nature Sustainability, researchers mostly from Pennsylvania State University (Penn State) in the U.S. reported the invention of a new coating that could reduce bacterial growth, water waste, and odor when sprayed onto an ordinary house toilet by rendering its surface too slippery for anything to remain attached for long.

According to the research team, half of all people worldwide are affected by limits on their water supply, while daily fresh water usage to flush the planet’s roughly 1 billion toilets and flush urinals is upwards of 141 billion liters (about 37 billion U.S. gallons, 31 billion imperial gallons); which they note is several times larger than the total rate of water consumption for the continent of Africa. Inventions that render the facilities more water-efficient, they reason, could have a profound impact on wastewater management, sustainable water use, and sanitation, possibly cutting the amount of water used to flush waste by, reportedly, a factor of two.

“Our team” study co-author Tak-Sing Wong said in a press release “has developed a robust bio-inspired, liquid, sludge-, and bacteria-repellent coating that can essentially make a toilet self-cleaning[.]” Wong is Penn State’s Wormley Early Career Professor of Engineering and an associate professor of mechanical engineering and biomedical engineering.

Co-developer Jing Wang recounted, “When we put that coating on a toilet in the lab and dump synthetic fecal matter on it, [the synthetic fecal matter] just completely slides down and nothing sticks to [the coated surface.]”

The more something sticks to a surface, the more water it takes to rinse it off. The researchers reported inventing a coating good at resisting substances that are sticky and vary profoundly in viscosity across their mass—like human fecal matter. They also reported the coating repels bacteria, which has implications for preventing the spread of disease and certainly reduces smells.

The invention, called a liquid-entrenched smooth surface (LESS) coating, involves two separate treatments, both presented as suitable for spraying onto ceramics amongst other materials. The first spray is made of molecularly grafted polymers, specifically polydimethylsiloxane silicone, that Wang described as resembling human hairs — though vastly thinner — once it has dried on the target surface, which makes the surface very smooth. The second spray covers the target surface in silicone lubricant. According to the report, the two-spray process is complete in under five minutes and lasts for roughly 500 flushes before requiring reapplication. Existing treatments have tended to take hours to set.

Carl Hensman of the Bill and Melinda Gates Foundation, which offered a contest for redesigning the toilet some years ago, noted the ingredients in the sprays are also found in commonly used products like — in the case of the first spray — toothpaste, and are unlikely to pollute nearby water supplies; though he also remarked that, because the spray wears off, it was unlikely to be used widely in developing countries as the researchers claim to hope.

Wong and three of his co-authors have started a company, spotLESS Materials, to transform their invention into a product. He remarked, “As a researcher in an academic setting, my goal is to invent things that everyone can benefit from […] As a Penn Stater, I see this culture being amplified through entrepreneurship, and I’m excited to contribute.” They have received support from the Rice Business Plan Competition, Ben Franklin Technology Partners’ TechCelerator, Y-Combinator, and the United States’ National Science Foundation, Department of Energy, and Office of Naval Research.

A team of eight transplant surgeons in Cleveland Clinic in Ohio, USA, led by reconstructive surgeon Dr. Maria Siemionow, age 58, have successfully performed the first almost total face transplant in the US, and the fourth globally, on a woman so horribly disfigured due to trauma, that cost her an eye. Two weeks ago Dr. Siemionow, in a 23-hour marathon surgery, replaced 80 percent of her face, by transplanting or grafting bone, nerve, blood vessels, muscles and skin harvested from a female donor’s cadaver.

The Clinic surgeons, in Wednesday’s news conference, described the details of the transplant but upon request, the team did not publish her name, age and cause of injury nor the donor’s identity. The patient’s family desired the reason for her transplant to remain confidential. The Los Angeles Times reported that the patient “had no upper jaw, nose, cheeks or lower eyelids and was unable to eat, talk, smile, smell or breathe on her own.” The clinic’s dermatology and plastic surgery chair, Francis Papay, described the nine hours phase of the procedure: “We transferred the skin, all the facial muscles in the upper face and mid-face, the upper lip, all of the nose, most of the sinuses around the nose, the upper jaw including the teeth, the facial nerve.” Thereafter, another team spent three hours sewing the woman’s blood vessels to that of the donor’s face to restore blood circulation, making the graft a success.

The New York Times reported that “three partial face transplants have been performed since 2005, two in France and one in China, all using facial tissue from a dead donor with permission from their families.” “Only the forehead, upper eyelids, lower lip, lower teeth and jaw are hers, the rest of her face comes from a cadaver; she could not eat on her own or breathe without a hole in her windpipe. About 77 square inches of tissue were transplanted from the donor,” it further described the details of the medical marvel. The patient, however, must take lifetime immunosuppressive drugs, also called antirejection drugs, which do not guarantee success. The transplant team said that in case of failure, it would replace the part with a skin graft taken from her own body.

Dr. Bohdan Pomahac, a Brigham and Women’s Hospital surgeon praised the recent medical development. “There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Leading bioethicist Arthur Caplan of the University of Pennsylvania withheld judgment on the Cleveland transplant amid grave concerns on the post-operation results. “The biggest ethical problem is dealing with failure — if your face rejects. It would be a living hell. If your face is falling off and you can’t eat and you can’t breathe and you’re suffering in a terrible manner that can’t be reversed, you need to put on the table assistance in dying. There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Dr Alex Clarke, of the Royal Free Hospital had praised the Clinic for its contribution to medicine. “It is a real step forward for people who have severe disfigurement and this operation has been done by a team who have really prepared and worked towards this for a number of years. These transplants have proven that the technical difficulties can be overcome and psychologically the patients are doing well. They have all have reacted positively and have begun to do things they were not able to before. All the things people thought were barriers to this kind of operations have been overcome,” she said.

The first partial face transplant surgery on a living human was performed on Isabelle Dinoire on November 27 2005, when she was 38, by Professor Bernard Devauchelle, assisted by Professor Jean-Michel Dubernard in Amiens, France. Her Labrador dog mauled her in May 2005. A triangle of face tissue including the nose and mouth was taken from a brain-dead female donor and grafted onto the patient. Scientists elsewhere have performed scalp and ear transplants. However, the claim is the first for a mouth and nose transplant. Experts say the mouth and nose are the most difficult parts of the face to transplant.

In 2004, the same Cleveland Clinic, became the first institution to approve this surgery and test it on cadavers. In October 2006, surgeon Peter Butler at London‘s Royal Free Hospital in the UK was given permission by the NHS ethics board to carry out a full face transplant. His team will select four adult patients (children cannot be selected due to concerns over consent), with operations being carried out at six month intervals. In March 2008, the treatment of 30-year-old neurofibromatosis victim Pascal Coler of France ended after having received what his doctors call the worlds first successful full face transplant.

Ethical concerns, psychological impact, problems relating to immunosuppression and consequences of technical failure have prevented teams from performing face transplant operations in the past, even though it has been technically possible to carry out such procedures for years.

Mr Iain Hutchison, of Barts and the London Hospital, warned of several problems with face transplants, such as blood vessels in the donated tissue clotting and immunosuppressants failing or increasing the patient’s risk of cancer. He also pointed out ethical issues with the fact that the procedure requires a “beating heart donor”. The transplant is carried out while the donor is brain dead, but still alive by use of a ventilator.

According to Stephen Wigmore, chair of British Transplantation Society’s ethics committee, it is unknown to what extent facial expressions will function in the long term. He said that it is not certain whether a patient could be left worse off in the case of a face transplant failing.

Mr Michael Earley, a member of the Royal College of Surgeon‘s facial transplantation working party, commented that if successful, the transplant would be “a major breakthrough in facial reconstruction” and “a major step forward for the facially disfigured.”

In Wednesday’s conference, Siemionow said “we know that there are so many patients there in their homes where they are hiding from society because they are afraid to walk to the grocery stores, they are afraid to go the the street.” “Our patient was called names and was humiliated. We very much hope that for this very special group of patients there is a hope that someday they will be able to go comfortably from their houses and enjoy the things we take for granted,” she added.

In response to the medical breakthrough, a British medical group led by Royal Free Hospital’s lead surgeon Dr Peter Butler, said they will finish the world’s first full face transplant within a year. “We hope to make an announcement about a full-face operation in the next 12 months. This latest operation shows how facial transplantation can help a particular group of the most severely facially injured people. These are people who would otherwise live a terrible twilight life, shut away from public gaze,” he said.
