Drone delivers transfusion blood intact

Thursday, December 8, 2016

In findings announced yesterday, scientists from Johns Hopkins University took ordinary commercial drones, swapped out their cameras for coolers and packed them with human plasma, platelets and blood cells. The drones were found to deliver their cargo in usable condition after flights lasting almost half an hour, at distances of up to 12 miles.

“For rural areas that lack access to nearby clinics, or that may lack the infrastructure for collecting blood products or transporting them on their own, drones can provide that access,” says pathologist and lead author of the paper Dr. Timothy Amukele.

Although earlier studies have confirmed that drone flights do not affect the useful properties or microbe populations of human blood products, those experiments were performed on small, vial-sized samples. Here, the drones carried much larger quantities of blood, in the proportions and packaging that doctors and medical technicians would actually use on patients, with units purchased directly from the American Red Cross. Unlike Rwanda’s medical delivery drones, which were custom-made for blood product delivery by Zipline, these experiments were completed with regular, commercially available S900-model machines with minimal modification.

Post-flight, the samples were tested for cell rupture, changes in pH, air bubbles and other damage that might indicate that the packages had thawed out or otherwise become unsuitable for use in transfusions. The samples were found to have arrived intact.

Although the test was performed in an unpopulated area, it is speculated that drones might be useful not only for delivery of blood products to rural medical facilities but also for distributing blood resources through urban areas. John’s Hopkins pathologist and research team leader Dr. Timothy Armukele speculates that emergency medical teams may one day be able to transfuse patients on the spot by calling for a drone to bring blood of the appropriate type.

The details of the experiment have been published in the latest issue of Transfusion.

Triple limb-reattachment fails – boy loses foot

Tuesday, April 5, 2005Terry Vo, the 10-year old Australian boy who had two hands and a foot reattached by surgeons after losing them in an accident, has had to have the foot re-amputated. He will be given a prosthetic foot in its place.

The operation to re-attach three limbs was thought to have been a first – but was ultimately unsuccessful, with the foot having died inside, and receiving insufficient blood supply following the surgery to reattach it.

“That would lead to the small muscles in the foot actually constricting, the toes bending over and a deformed …. foot that is sort of clawed over and doesn’t have good sensation,” said plastic surgeon, Mr Robert Love today, on Australia’s ABC Radio.

“Even if you can get all of that to survive, he [would be] worse off than having had an amputation.”

“What is very disappointing is that for the first two days after [the operation] the foot looked absolutely magnificent,” he said.

Terry’s hands were healing well, said the surgeon. The prosthetic foot would allow him to walk normally, since his knee was intact.

Obama to suspend Arctic oil drilling

Obama to suspend Arctic oil drilling

According to Democratic Senator Mark Begich from Alaska, the U.S. Department of the Interior has decided to halt all new Arctic exploratory oil drilling applications until 2011. The response is believed to be caused in part by the two current oil spill disasters (that of the Deepwater Horizon Incident and more recently the Alaska oil pipeline malfunction). However, Begich is not happy about the actions taken by the White House.

“I am frustrated that this decision by the Obama administration to halt offshore development for a year will cause more delays and higher costs for domestic oil and gas production to meet the nation’s energy needs,” Begich claims.

Last September, the state of Alaska made a public notice about Shell’s desire to drill off the coast of the Beaufort Sea, placing experimental drilling rigs at two drill site location: “Torpedo” and “Sivulliq”.

“Shell is committed to undertaking a safe and environmentally responsible exploration program in the Chukchi Sea and Beaufort Sea in 2010,” said Shell Oil Company President Marvin E. Odum to the U.S. Department of the Interior’s Mineral Management Service (MMS).

Odum follows with, “I am confident that we are ready to conduct the 2010 Arctic exploratory program safely and, I want to be clear, the accountability for this program rests with Shell.”

Chuck Clausen, director of the Alaska project at the National Resources Defense Council is not so optimistic: “Hazards present in the Arctic can include frigid temperatures, presence of sea ice, gale-force winds, intense storms and heavy fog … The potential for loss in the Arctic is great.”

Odum believes that the climate in the arctic will make any spill easier to clean up because, “Arctic conditions create differences in responding to oil in cold and ice conditions. Differences in evaporation rates, viscosity and weathering provide greater opportunities to recover oil. In Arctic conditions, ice can aid oil spill response by slowing oil weathering, dampening waves, preventing oil from spreading over large distances, and allowing more time to respond.”

However, Clausen believes that there are no current systems to remove oil from icy ocean waters.

This is not the first time that President Obama’s administration has taken the environmentally cautious path in Alaska. The President put Bristol Bay off limits to oil and gas exploration until 2017. Bristol Bay currently is one of the top salmon fishing grounds in the state.

Interior Secretary Ken Salazar is expected to give a speech at Thursday’s White House address, regarding the suspension of Arctic oil drilling projects.

At Thanksgiving dinner David Shankbone told his white middle class family that he was to interview Reverend Al Sharpton that Saturday. The announcement caused an impassioned discussion about the civil rights leader’s work, the problems facing the black community and whether Sharpton helps or hurts his cause. Opinion was divided. “He’s an opportunist.” “He only stirs things up.” “Why do I always see his face when there’s a problem?”

Shankbone went to the National Action Network’s headquarters in Harlem with this Thanksgiving discussion to inform the conversation. Below is his interview with Al Sharpton on everything from Tawana Brawley, his purported feud with Barack Obama, criticism by influential African Americans such as Clarence Page, his experience running for President, to how he never expected he would see fifty (he is now 53). “People would say to me, ‘Now that I hear you, even if I disagree with you I don’t think you’re as bad as I thought,'” said Sharpton. “I would say, ‘Let me ask you a question: what was “bad as you thought”?’ And they couldn’t say. They don’t know why they think you’re bad, they just know you’re supposed to be bad because the right wing tells them you’re bad.”

UK company “seriously considering” GPS tracking devices in school uniforms

UK company “seriously considering” GPS tracking devices in school uniforms
May 15, 2019 - Posted by Gvmawv3B - 0 Comments

Saturday, August 25, 2007

The leading supplier of school uniforms in the United Kingdom, Lancashire-based manufacturer Trutex, has announced it is “seriously considering” including GPS tracking devices in future ranges of its uniform products after conducting an online survey of both parents and children.

“As a direct result of the survey, we are now seriously considering incorporating a [tracking] device into future ranges” said Trutex marketing director Clare Rix.

The survey questioned 809 parents and 444 children aged nine to 16. It showed that 44% of parents were worried about the safety of pre-teen children, and 59% wanted tracking devices installed in school apparel. 39% of children aged nine to 12 were prepared to wear clothing with tracking devices in them, while teenagers were notably less enthusiastic and more wary of what Trutex has admitted they see as a “big brother” concept.

However, Trutex has claimed the tracking devices would bring about worthwhile benefits, including being a valuable resource for parents who wanted to keep a close eye on where their children were at all times.

“As well as being a safety net for parents, there could be real benefits for schools who could keep a closer track on the whereabouts of their pupils, potentially reducing truancy levels” says Rix.

Each year, Trutex supplies 1 million blouses, 1.1 million shirts, 250,000 pairs of trousers, 20,000 blazers, 60,000 skirts and 110,000 pieces of knitwear to the UK.

It is not the first company to manufacture school uniforms with a central focus on child safety; last week Essex firm BladeRunner revealed it was selling stab-proof school blazers to parents concerned about violence against their children. The blazers were outfitted with Kevlar, a synthetic fibre used in body armour. It has already received orders internationally, including Australia.

If the Trutex tracking devices go ahead, it is unclear where in the uniform they will be located.

Teen charged over ‘bomb attempt’ at US Christmas celebration

The threat was very real. Our investigation shows that Mohamud was absolutely committed to carrying out an attack on a very grand scale.

A 19-year-old Oregon, U.S. resident has been charged with attempting to use a weapon of mass destruction after a sting operation; authorities say Mohamed Osman Mohamud, born in Somalia, tried to detonate a van bomb using a mobile phone at a Christmas tree lighting ceremony in Portland.

The device, police stated, was fake; he reportedly obtained it from undercover agents during a sting operation. Reports say Mohamud, a US citizen, had been in regular contact with somebody in north-west Pakistan.

Authorities intercepted e-mails they say were between Mohamud and this contact in August 2009. Holton reassured Oregon residents, adding that there was “no reason to believe there is any continuing threat arising from this case”. Mohamud allegededly told an FBI agent “I want whoever is attending that event to leave, to leave either dead or injured.” Dwight Holton, a U.S. attorney, described Mohamud’s “chilling determination” as a “stark reminder that there are people—even here in Oregon—who are determined to kill Americans.”

An FBI agent told reporters “[t]he threat was very real. Our investigation shows that Mohamud was absolutely committed to carrying out an attack on a very grand scale. I want to reassure the people of this community that, at every turn, we denied him the ability to actually carry out the attack.” On the day of the tree lighting ceremony, he drove a vehicle to the area where the event was to be held, and was arrested, prosecutors said, twenty minutes before the tree was to be lit. He kicked at agents as they tried to apprehend him and shouted “Allahu Akbar!” (God is great!).

Court papers indicated that an undercover agent told Mohamud that he was an associate of the Pakistani contact. When the agent and Mohamud discussed the plan, Mohamud said that he wanted a “huge mass that will be attacked in their own element with their families celebrating the holidays”. Mohamud told the agent that he had wanted to carry out a jihad (holy war) against the U.S. since he was fifteen years old.

British surfers catch more than waves: Scientists find antibiotic-resistant bacteria

British surfers catch more than waves: Scientists find antibiotic-resistant bacteria
May 11, 2019 - Posted by Gvmawv3B - 0 Comments

Wednesday, January 17, 2018

In findings published Sunday in Environmental International, a team from Britain’s University of Exeter reports that surfers and bodyboarders are roughly three times as likely to house antibiotic-resistant Escherichia coli and other bacteria that could easily become resistant, than other people who recreate in the coastal waters of the United Kingdom.

The epidemiological study was nicknamed the “Beach Bum Survey”. The project was performed on 143 regular surfers, body surfers and bodyboarders from around the United Kingdom. Each surfgoing participant was asked to recruit a non-surfing friend of the same sex and approximate age and who lived in the same part of the country to serve as a control, which resulted in a control group of 130.

All participants mailed in rectal swabs, and the researchers cultured the E. coli from those samples with a common antibiotic called cefotaxime. The antibiotic failed to kill the bacteria in about 9% (13 out of 143) of surfer and bodyboarder samples and 3% of the samples from the control group (4 out of 130). A deeper look into the genomes of the specific strains of bacteria found in the study volunteers showed that bacteria from surfers were four times as likely to possess genes that can be transferred from one bacterial strain to another, which can help antibiotic-susceptible bacteria become resistant. The study also involved examination of water samples from the coasts of England and Wales to estimate the risk of surfers and other beachgoers ingesting E. coli.

E. coli is a regular resident in the guts of humans and other animals. Most strains are harmless but others can cause serious disease. Like other bacteria, E. coli can undergo horizontal gene transfer, swapping genes from one bacterium to another. This can give the altered strain the ability to cause disease, survive in the presence of antibiotics or both.

Although the researchers expressed concern surfers might spread dangerous bacteria, Dr. Will Gaze, the University of Exeter Medical School professional who supervised the project, urged people not to avoid the beach: “We are not seeking to discourage people from spending time in the sea, an activity which has a lot of benefits in terms of exercise, well-being and connecting with nature”, he said. “It is important that people understand the risks involved so that they can make informed decisions about their bathing and sporting habits. We now hope that our results will help policy-makers, beach managers, and water companies to make evidence-based decisions to improve water quality even further for the benefit of public health.”

David Smith, science and policy officer of Surfers Against Sewage, which helped organise the volunteers, agreed the study was not meant to discourage surfing: “Water quality in the UK has improved vastly in the past 30 years and is some of the cleanest in Europe. Recognising coastal waters as a pathway for antibiotic resistance can allow policy makers to make changes to protect water users and the wider public from the threat of antibiotic resistance.”

One of the principal findings of this work was that existing methods may have been underestimating the prevalence of these bacteria in seawater. Previous studies have shown that even designated swimming beaches can be affected by runoff from farms or even sewage, and surfers swallow roughly ten times as much seawater as swimmers. Professor Colin Gardner of the charity Antibiotic Research UK says, these forms of runoff can have even higher concentrations of antibiotics than patients undergoing antibiotic treatment. “Research into new medicines to replace our archaic antibiotics has stagnated and unless new treatments are found, this could be potentially devastating for human health”, he warns.

The World Health Organization has reported that because so many kinds of bacteria are gaining resistance to common medicines, conditions such as pneumonia and gonnorhea may become more difficult to treat and have higher rates of sickness and death. Doctors often prescribe preventative antibiotics to patients undergoing surgery or radiation therapy, and this may also be impacted. Professor Sally Davies, England’s chief medical officer, has described a “post-antibiotic apocalypse” scenario

The European Regional Development Fund and Natural Environment Research Council provided funding for the study.

Thursday, July 3, 2008

69-year-old grandfather John Walsh stands accused of murdering three victims in the small New South Wales town of Cowra. All victims were killed in different ways.

Media organisations have reported that the 69-year-old man killed his five year old grand daughter by drowning; her seven year old brother was killed by a blunt force trauma to the back of the head, and his wife was killed by multiple axe wounds to her body – including her head.

New South Wales Police could not confirm the post-mortem examination, saying that the results of the post-mortem examination are not expected to be finalised for a couple of days and may not be immediately made public.

The 69-year-old man, who went before Deniliquin Local Court on July 1, 2008, was refused bail and charged with three counts of murder and one count of attempted murder. He is currently in a special holding cell on 24-hour watch at the Junee Correctional Centre. A further appearance is due in Wagga Wagga Local Court via an audio-visual link on July 7, 2008.
