ScienceDaily (Oct. 17, 2012) ? Patients with chest pain symptoms who call an ambulance have quicker, more appropriate treatment and better survival according to research presented at the Acute Cardiac Care Congress 2012. A study from Denmark shows that calling emergency services allows pre-hospital triage and transport to the most appropriate hospital, while a Turkish study reveals that only 29% of patients with chest pain went to hospital by ambulance.

The Acute Cardiac Care Congress 2012 is the first annual meeting of the newly launched Acute Cardiovascular Care Association (ACCA) of the European Society of Cardiology (ESC). It takes place from 20 to 22 October in Istanbul, Turkey, at the Istanbul Lufti Kirdar Convention and Exhibition Centre (ICEC).

Primary percutaneous coronary intervention (pPCI), also called balloon treatment, opens the coronary vessel and is preferred over intravenous (IV) medicine (called thrombolysis) to dissolve blood clots in patients with heart attacks. To deliver this care, patients must be transported to a hospital that can provide balloon treatment. This requires well functioning treatment networks which integrate the pre-hospital and in-hospital phases of patient management so that even patients in remote areas receive high quality treatment that adheres to ESC Clinical Practice Guidelines.

"Transporting patients to hospitals with balloon treatment capacity often involves bypassing local hospitals in the vicinity of the patient," said Dr Mikkel M. Schoos from the University Hospital of Copenhagen, Denmark. "Pre-hospital triage involves digital transmission of the ambulance electrocardiogram (ECG) using telemedicine to the attending cardiologist at the hospital with the balloon capacity who can decide if the patient needs balloon treatment."

He added: "In this way, patients can be referred directly to the hospital that can perform balloon treatment, without first being seen in a local emergency room. This saves important time. We know from previous studies that reduced time to treatment equals greater salvage of the heart tissue near the blood clot after a heart attack."

Dr Schoos' study investigated the quality of these treatment networks in Denmark. The researchers found that 75% of all patients can be transferred directly to hospitals with balloon treatment capacity using pre-hospital triage.

But even when well functioning pre-hospital triage with telemedicine is in place, for 25% of patients it is not possible to deliver treatment within the time targets recommended by ESC Clinical Practice Guidelines if only ground ambulance is used. These are patients who live more than 100km (60 miles) away from the hospital with balloon treatment facilities and patients who go to a local hospital first.

The study showed that patients who are first brought to a local hospital lose important time and this increases their risk of death. "The time delay caused by first being taken to a local hospital that does not have the treatment facilities the patient needs is bad for the patient," said Dr Schoos. "Our study also shows that this system delay predicts all cause mortality in these patients who have big heart attacks. That means that a pit stop at a local hospital increases the risk of death."

There are several reasons why patients might go to the local hospital first. One is that the heart attack is not developed enough to be detected and diagnosed by the ambulance ECG. Dr Schoos is currently investigating ways to improve early diagnosis with ECG or biomarkers in the blood. A second reason could be a failure to transmit the ambulance ECG to the hospital. A third reason is that emergency medical personnel are not confident that the patient is stable enough for further transport and decide to do a pit stop at a local hospital.

Dr Schoos said: "By doing that they postpone the only right treatment. The majority of patients with acute heart attacks can be safely transported to a hospital with the needed treatment capacity, even if these hospitals are further away than smaller local hospitals."

He added: "Even though patients might get arrhythmias, which are bad heart rhythms, as a consequence of their blood clot, these can easily be treated in the ambulance by well educated emergency medical staff."

Ambulance staff must also be educated to perform and transmit the ECGs. "We need people with the right education in the ambulance for these treatment networks to function properly," said Dr Schoos.

Dr Schoos continued: "Patients and their relatives should call the emergency telephone number (112 in Denmark and Turkey) at the first symptoms of a heart attack. Valuable time is lost when patients drive themselves to emergency rooms or are driven there by relatives and they could develop a bad heart rhythm on the way. Ambulance staff can do an ECG straightaway, even in the patient's home, and ensure that patients are taken to the right hospital immediately."

He added: "Calling emergency is also important in countries that don't use pre-hospital triage with telemedicine because ambulance staff can give anti-thrombotic medicine to dissolve or stop the development of a blood clot."

To improve treatment for patients who live more than 100km away from a hospital with balloon treatment, Dr Schoos recommended arranging the catchment area of a hospital into geographical zones. This would make it possible to identify patients who might have long treatment delays because they live further away.

Geographical zone 1 could be for patients who live within 100km of the balloon treatment centre. These patients can receive pre-hospital triage with telemedicine. Geographical zone 2 is for patients more than 100km away. These patients could be transferred by helicopter, or be treated first with clot dissolving drugs (thrombolysis) followed by balloon treatment when they arrive at the centre.

In the second study, Dr Burcu Demirkan from the Turkiye Yuksek Ihtisas Hospital in Ankara, Turkey, investigated the factors influencing the use of an ambulance among Turkish patients with an acute coronary syndrome (ACS).

"Until recently there was a limited ambulance service in Turkey but the Ministry of Health has now made it available for the whole country," said Dr Demirkan. "The service is free of charge and quicker than in the past. Despite these improvements most patients still prefer self transport instead of using an ambulance when they have acute chest pain."

For the study the researchers collected data from 330 patients with ACS from 2 hospitals (a state hospital without pPCI capability and an education and research hospital that could perform pPCI).

The study found that just 29% of patients went to hospital by ambulance. This was despite the fact that 68% of patients knew the emergency telephone number (112). There were no differences in age, gender and marital status between patients who called an ambulance and patients who did not.

Patients who called an ambulance had a higher level of education, greater knowledge of the risk factors for coronary artery disease, and greater awareness of the fact that chest pain is related to heart attack and patients should quickly seek medical care. These patients were also more likely to have ST-elevation myocardial infarction (STEMI) (as opposed to non-STEMI), vertigo, syncope/near syncope, nausea, vomiting and more severe chest pain.

Among patients who did not use an ambulance, 37% were given a lift, 14% drove their own car, 26% took a taxi, 12% used public transport and 11% walked to the hospital.

Most patients (whether they used an ambulance or did not) were accompanied by family members or friends during transportation to the hospital.

Dr Demirkan said: "Less than one third of Turkish ACS patients used an ambulance for transportation to the hospital even though this service is free. This rate was lower than rates from previous studies in European countries and Australia but similar to rates in China."

She added: "The perception of symptoms as not serious or not of cardiac origin was the most common reason for not calling an ambulance. However among the patients who considered the symptoms to be serious, most of them thought that self transport would be faster. Contrary to the assumption of these patients, we found that ambulance users arrived at the hospital more quickly."

Dr Demirkan continued: "Instead of using an ambulance most of our patients used transportation that was unsafe and inappropriate for ACS patients, who urgently need reperfusion therapy. This situation was due to patients' misperceptions about the symptoms of a heart attack or false assumptions that self transport would be quicker."

She concluded: "Our study improves understanding of the reasons why patients do not call an ambulance and will help with planning health education programmes to increase ambulance use. Such programmes should teach patients about the characteristics of chest pain related to heart attack and the importance of calling 112 when they experience these symptoms."

Fujitsu has just revealed its Windows 8 lineup for the Japanese market, and top billing goes to the new "Floral Kiss" Ultrabook, which the manufacturer claims was built "under the direction" of its female employees in order to entice an equally female audience. At heart, it's just a regular Core i5 notebook with a 500GB hard drive, but the womanliness is all in the presentation. There are subtle color schemes like "feminine pink" and "luxury brown" to choose from and every laptop comes with pre-installed Windows 8 apps including a digital scrapbook for collecting website bookmarks, a diary and a daily horoscope checker. This almost oppressively enticing bundle will hit stores on November 2nd, with some sort of premium designer version arriving a few weeks later. As for the exact price, that'll be determined by retailers in Japan and by how good your husband is at haggling.

I told sw that the school pictures were taken and here our state will pay for them. I paid upfront and then was paid back. In our situation no bios were involved. Sw wanted pictures for Angel's file so she will have pictures of her life but the soon to be adoptive mom and I split the rest of the pictures. I wanted at least one to hang on my wall since Angel wondered why there were pictures of my boys and not her. Seemed like a valid point. I think I would give the parents the child's picture id number that they give with school pictures and let the parents know that the pictures look cute if they want to order any. Give them the sample page of how they turned out if you have one. It is none of their business that you have the pictures if you paid for them. If you take a picture with your camera you're not expected to turn it over to the parents. Just give them the ability to order some not mooch off of your parenting.

BEIJING (Reuters) - A Chinese firm that has sued U.S. President Barack Obama for blocking its wind farm project pledged to fight "to the very end" the security-related order, saying it was placing its faith in the U.S. justice system.

Obama's order for Ralls Corp to divest its interests in the projects, near a military facility, marked the first time since 1990 that a U.S. president has formally blocked a business transaction on security grounds, and comes amid heightened tensions between the United States and China over trade actions by the U.S. administration.

Ralls, which is owned by two executives of China's Sany Group, was installing wind turbines made by Sany close to a naval training site in Oregon which, according to the facility's web site, is used to test unmanned drones - a highly sensitive and prized U.S. technology.

The lawsuit is viewed as a long shot given the president's broad authority on national security matters and the fact that courts do not often second guess the executive branch on security issues.

But Ralls Chief Executive Wu Jialiang, one of the Sany executives who owns the company, said he was determined to press ahead.

"We are full of confidence that we will win this lawsuit because we are innocent. We believe in justice and the equality the U.S. legal system represents," Wu told a news conference in Beijing.

"We will fight till the very end," he said, adding that the U.S. action was partly motivated by politicians seeking to score points ahead of the U.S. presidential election and that it could cost thousands of U.S. jobs.

U.S. SUSPICIONS

Ralls has also incurred investment losses of more than $20 million as a result of the action, he said.

Ralls argues that Obama exceeded his power by dictating the terms of the sale, allowing the government to inspect all aspects of its operations and not treating the company equally as required under the law.

Sources close to Ralls have also said there are other wind farms owned by foreign competitors in the area.

But experts say Ralls greatly underestimated U.S. suspicions about Chinese intentions.

In addition to the wind farm dispute, a U.S. congressional committee has urged U.S. companies to stop doing business with two Chinese telecom equipment makers, Huawei Technologies Co Ltd and ZTE Corp, over security concerns.

Tim Xia, an attorney representing Ralls, acknowledged that the case will be tough.

"It is really difficult to win the case. However, I believe that in a society governed by the rules of law, nobody can be above the Constitution of the United States, not even the president even in the name of national security," he told the news conference.

Sany Group is the parent company of Shanghai-listed Sany Heavy Industry Co, China's largest construction equipment maker. The group is owned by Chairman Liang Wengen, who is China's fifth richest man, according to the latest ranking by the Hurun Report.

Obama's order followed a recommendation from the Committee on Foreign Investment in the United States, an inter-agency group headed up by the Treasury secretary that evaluates the national security risks of foreign investments in U.S. companies or operations. Ralls is also suing the committee.

This week brings three new major releases to Triangle cinemas, at least two of which are vying for Taken 2?s spot at the top of the charts. We?ve got Tyler Perry?s action debut in Alex Cross; the latest chapter in the Paranormal Activity saga; and an Oscar contender for Best Documentary with Searching for Sugar Man. Enough time?s been wasted, let?s get started.

The character of Alex Cross first graced screens in the 1997 thriller Kiss the Girls and its quasi-sequel, Along Came a Spider. Those two films starred Morgan Freeman in the role of Cross, a brilliant police detective that used his forensic psychology skills to greater use than a gun. Girls did pretty good at the box office, while Spider languished, basically killing the franchise until Summit Entertainment decided that bringing a mostly forgotten character back to the screen could somehow win over both audiences looking for something that wasn?t created in a comic book, and those that looked back at the original series with fondness.

Alex Cross stars Tyler Perry as the titular character. Here we meet the young detective for the first time, making a name for himself on the streets of Detroit as the best cop in the city. When a wealthy young woman is brutally tortured and murdered, Cross and his team (which includes Edward Burns, Mr. Box Office Poison himself) manage to crack the killer?s (Lost?s Matthew Fox) code and save his next victim from the same grisly fate. Taking this as a personal insult, the killer then sets his sights on Cross? family and friends for revenge.

Your opinion on Alex Cross will largely depend on whether you can buy Tyler Perry, forever to be known for starring as Madea and making a bazillion dollars in the process, as a tough-as-nails Detroit cop. This is the type of character that, even when he?s off the screen for five minutes, the supporting characters spend that time discussing how brilliant he is. It seems almost unfair to point out that the directing and script are horrible, as the acting wouldn?t have been any better if an A-lister was behind the camera. The first time Perry knocks someone out with an open-handed slap, I checked out. Skip this one; if you?re a Perry fan, just drop an extra buck in the collection plate Sunday morning to alleviate the guilt a little.

Next up we have the latest entry in a very lucrative franchise, Paranormal Activity 4. I just realized today that this series has officially taken over as the cheapie Halloween release from Saw, as that franchise quit pumping out quickie sequels almost immediately after the success of PA.?And why shouldn?t Hollywood acquiesce that title onto PA? Whereas almost any other studio would feel no qualms in throwing anyone with half a script and a grasp of which end of the camera to stand behind at the franchise to keep it rolling, Paramount has actually nurtured it along with a creative streak not seen in years from a major studio. By looking toward directors of the most buzzed about documentaries and offering them their first major studio gigs, the PA series is 3-for-3 in quality entertainment that doesn?t cost a bundle. So with Henry Joost and Ariel Schulman, the directors of both the controversial ?doc? Catfish and Paranormal Activity 3, invited back to oversee the fourth installment, where does it rank among the other installments of the series?

PA 4 opens up five years after the events of the first two films. Katie and Hunter are still missing, and there have been no clues as to where the pair has gone in that time. A family in Nevada befriends a small boy who has just moved in across the street, and after his mother is hospitalized, takes him into their home for a few days while the mom recuperates. The boy is stand-offish and talks to an invisible friend for much of the time, until he starts focusing on getting the son in this family ?ready? to meet this invisible entity. Before you know it chairs are sliding across floors, toys are mysteriously lining up in hallways, and knives are disappearing. Spooooooooooooky!

Here?s the thing: I?m a sucker for these movies. For all of the detractors that ask, ?Who?s scared of a door opening and closing?? the answer is me. I watch these films, and spend the rest of the night hearing my house make noises and assuming that I?m about to die. In my mind, there is something much more scary about an entity you can?t put your hands on screwing around with your property than your generic undead boogie man attempting to stalk you. That is what is so ingenious about the PA series; by taking that which we are most familiar with in our day to day lives, and turning those very things against us, we are left with a feeling of helplessness and horror. PA4 falls in line with the first three films, and is a fine choice for your Halloween viewing this year.

Finally, we have the most buzzed about documentary of the year, Searching for Sugar Man. In the early 70s, Rodriguez was just another struggling folk singer with a small group of fans that watched him play in the bars around Detroit. After releasing two albums that were met by the public with general indifference, the troubadour disappeared from the music scene, leaving behind nothing but whispers about an unappreciated genius and tales of a suicide performed on stage.

What wasn?t known at the time was that those albums were huge hits in South Africa. Discovered by a generation tired and confused by the apartheid movement that surrounded them, they latched onto the words they heard coming from Rodriguez?s records and took them to heart. The albums were such successes that they quickly went gold ten times over, without the news ever reaching America that someone finally appreciated the singer?s brilliance.

Sugar Man walks you through this story, showing you firsthand how dangerous it was for these groups of kids to listen to music that the government at that time labeled as subversive. Whereas many here might consider the music to be just another example of the folksingers of the time who were all attempting to be lesser versions of Bob Dylan, youths in South Africa found the singer to be the voice of their struggle. In fact, it is said in the film that in a liberal family?s home at the time you would find three albums: The Beatle?s ?Abbey Road?, Simon & Garfunkel?s ?Bridge Over Troubled Water?, and Rodriguez?s debut title; many assumed he was as big in America as the other two acts.

Decades later, a South African music reporter in search of a story decides to finally investigate the tale of Rodriguez and his rumored death. Along with a record store owner that regards himself as one of the singer?s biggest fans, they begin to unravel the mystery surrounding the elusive songwriter.
Sugar Man?s biggest strength is its ability to avoid all of the Behind the Music clich?s that befall almost any musical doc. We are not given the sugar-coated rags to riches story that has become the norm for these types of films. Instead, we are shown how one man can cause change, no matter how small, and provide comfort to a people in desperate need for it. What we, the viewer, are receiving is one of the most entertaining yet powerful films of the year, and a sure-fire contender at the Oscars this year.

So in review:
? Avoid Alex Cross, unless you have some ulterior motive for watching it
? Paranormal Activity 4 is a fine film to get your Halloween season started
? Searching for Sugar Man will probably be one of the best films you watch all year

CEATEC isn't exactly the first place you'd expect a new notebook to turn up, but Fujitsu's booth had a bit of a surprise on the laptop front. The Japanese company had its Lifebook UH75 Ultrabook on display running Windows 8. That OS is the real news here: no other real specs beside the 14-inch screen we already knew about. Fujitsu said this machine will launch alongside its new Arrows Tab sometime in late October or November. Check out our video hands-on below the break.

Nano-hillocks: Of mountains and craters

ScienceDaily (Oct. 1, 2012) ? In the field of nanotechnology, electrically-charged particles are frequently used as tools for surface modification. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the TU Vienna were at last able to reconcile important issues concerning the effects of highly charged ions on surfaces.

Ion beams have been used for some time now for surface modification as ions are capable of carrying such high energies that a single particle alone can induce drastic changes to the surface under bombardment. Following careful examination, an international team of researchers was at last able to shed light on the reasons why sometimes craters and other times hillocks are forming as a result of this process. Their findings have recently been published in the scientific journal, Physical Review Letters.

Charge instead of speed

"If the goal is to deposit a maximum amount of energy on a tiny spot on the surface, it is of comparatively little use to simply bombard the surface with fast atoms," explains Prof. Friedrich Aumayr of the TU Vienna's Institute of Applied Physics. "Fast particles penetrate deep into the material thereby depositing their energy over a wide range." If, however, you first strip a large number of electrons from individual atoms and then allow these highly charged ions to collide with the material surface, the effects you get are quite dramatic as the energy that was previously required to ionize the atoms is now being released within a very small area of a few nanometers in diameter, and within an ultrashort time.

This can lead to melting of a very small volume of the material, loss of its orderly atomic structure, and, finally, its expansion. The large number of electronic excitations that result from the ion's interactions with the surface has a strong impact on the material and ultimately leads to the atoms being bumped out of position. The end-result is nano-hillock formation -- the appearance of tiny protrusions on the material's surface. If the energy required to initiate melting of the material is insufficient, small holes or defects will form on or below the surface instead.

Elaborate experiments at the HZDR facility for highly charged ions were just as important to obtaining a detailed picture of the processes that take place at the material's surface as were computer simulations and extensive theoretical work. "At our new HZDR facility, we have the capabilities for deliberately forming nano-hillocks and nano-craters on surfaces. In close collaboration with the groups of our colleagues Friedrich Aumayr and Joachim Burgd?rfer at the TU Vienna we succeeded to grasp the underlying physical mechanisms in more detail," explains Dr. Stefan Facsko. Egyptian physicist Dr. Ayman El-Said, who spent two years as a Humboldt Foundation fellow conducting research at HZDR, made substantial contributions to the current body of research in this field.

Assumptions confirmed

The scientists are calling their results the missing important piece of the puzzle to help them understand the interaction of highly charged ions with surfaces. By subjecting the sample to an acid treatment following ion bombardment, they are able to document the extent to which a surface is modified at given energies. The formation of nano-hillocks depends to a large extent on the ion beams' charge state and to a lesser extent on their velocity. The formation of craters, on the other hand, is dependent upon both the charge state and the kinetic energy of the ions. The Vienna and Dresden researchers had long suspected this and were now at last able to produce the necessary evidence obtained from their experiments conducted at the HZDR.
