Intensive care teams inside hospitals are rapidly altering the way they care for patients with COVID-19.

The changes range from new protective gear to new treatment protocols aimed at preventing deadly blood clots.

"Things are moving so fast within this pandemic, it's hard to keep up" says Dr. Angela Hewlett, an infectious diseases physician at University of Nebraska Medical Center in Omaha and medical director of the Nebraska Biocontainment Unit. To stay current, she says, ICUs are updating their practices "on an hourly basis."

"We are learning at light speed about the disease," says Dr. Craig Coopersmith , interim director of the critical care center at Emory University. "Things that previously might have taken us years to learn, we're learning in a week or two. Things that might have taken us a month to learn beforehand, we're learning in a day or two."

The most obvious changes involve measures to protect ICU doctors, nurses and staff from the virus.

"There is a true and real probability of infection," says Dr. Tiffany Osborn a critical care specialist at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis. "You have to think about everything you touch as if it burned."

So ICUs are adapting measures used at special biocontainment units like the one at the University of Nebraska. These units were designed to care for patients affected by bioterrorism or infected with particularly hazardous communicable diseases like SARS and Ebola.

The Nebraska biocontainment unit "received several patients early on in the pandemic who were medically evacuated from the Diamond Princess cruise ship," Hewlett says. But it didn't have enough beds for the large numbers of local patients who began arriving at the University of Nebraska Medical Center.

So the nurses, respiratory therapists and physicians from the biocontainment team have "fanned out and are now working within those COVID units to make sure that all of our principles and protocols are followed there as well," Hewlett says.

Those protocols involve measures like monitoring ICU staff when they remove their protective gear to make sure the virus isn't transmitted, and placing infected patients in negative pressure rooms, which draw air inward, when possible to prevent the virus from escaping.

One of the riskiest ICU procedures is inserting a breathing tube in a COVID-19 patient's airway, which creates a direct path for virus to escape from a patient's lungs. "If you're intubating a patient, that's a much higher risk than, say, going in and doing routine patient care," Hewlett says.

So ICU teams are being advised to add several layers of protection beyond a surgical mask.

Extra personal protective equipment may include an N95 respirator, goggles, a full face shield, a head hood, an impermeable isolation gown and double gloves.

In many ICUs, teams are also placing a clear plastic box or sheet over the patient's head and upper body before inserting the tube. And as a final safety measure, the doctor may guide the tube using a video camera rather than looking directly down a patient's airway.

"It usually takes 30 minutes or so in order to get all of that equipment together, to get all of the right people there," says Dr. Kira Newman, a senior resident physician at UW Medical Center in Seattle. "and that would be a particularly fast intubation."

But most changes in the ICU are in response to an ongoing flood of new information about how COVID-19 affects the body.

There's a growing understanding, for example, that the infection can cause dangerous blood clots to form in many severely ill patients. These clots can kill if they block arteries supplying the lungs or brain. But they also can prevent blood from reaching the kidneys or even a patient's arms and legs.

Clots are a known risk for all ICU patients, Cooperman says, but the frequency and severity appears much greater with COVID-19. "So we're starting them on a higher level of medicine to prevent blood clots and if somebody actually develops blood clots, we have a plan B and a plan C and a plan D," he says.

ICU teams are also recalibrating their approach to ensuring that patients are getting enough oxygen. Early in the pandemic, the idea was to put patients on mechanical ventilator quickly to make sure their oxygen levels didn't fall too far.

But with experience, doctors have found that mechanical ventilators don't seem to work as well for COVID patients as they do for patients with other lung problems. They've also learned that that many COVID-19 patients remain lucid and relatively comfortable even when the oxygen levels in their blood are extremely low.

So many specialists are now recommending alternatives to mechanical ventilation, even for some of the sickest patients. "We're really trying now to not intubate," Osborn says.

Instead, ICU teams are relying on devices that deliver oxygen through the nasal passages, or through a mask that fits tightly over the face. And there's renewed interest in an old technique to help patients breathe. It's called proning.

"Instead of them being on their back, we're turning them on their front," Osborn says. The reason, she says is to open up a part of the lung that is collapsed when a patient is on their back.

The White House coronavirus task force rejected detailed guidance drafted by the Centers for Disease Control and Prevention on how workplaces ranging from schools to bars to churches should resume operations to prevent the spread of the virus because it was viewed as "overly prescriptive."

President Trump has said he wants to see the country begin to reopen. The pandemic crashed the economy by keeping people at home, leading to millions of job losses. The White House task force issued guidelines on how to gradually and safely reopen but left decisions up to governors based on conditions in their states.

Experts have warned that a rush to reopen could have disastrous implications for containing COVID-19. Many businesses have said they want more details about how to do things safely.

The draft detailed guidance was provided to the task force in late April, a couple of weeks after it released its April 16 guidance to states for reopening.

The task force sought "certain revisions" to the CDC's detailed guidance, two administration officials told NPR. But revised recommendations were never returned to the task force.

The Associated Press first reported on the task force decision to shelve the detailed guidance. Copies obtained and published by the AP, The New York Times and The Washington Post revealed detailed, staged directions for child care centers, schools, camps, restaurants and bars, churches and mass transit providers about how to safely resume operations.

"I think many people would argue that it is not the role of the federal government to tell specific entities — whether they be schools or churches or businesses — how they should go about doing things because the nation is so diverse," one of the administration officials said.

The task force said that some of the points may be helpful, but they needed to "zoom out a little bit and not be so prescriptive," according to the official. The task force said they would welcome a new set of recommendations, but that never happened, the official said.

"Issuing overly specific instructions — that CDC leadership never cleared — for how various types of businesses open up would be overly prescriptive and broad for the various circumstances states are experiencing throughout the country," the second administration official said. "Guidance in rural Tennessee shouldn't be the same guidance for urban New York City."

The United States last month reached 1 million known coronavirus cases, representing one-third of all coronavirus cases worldwide. Nearly 74,000 Americans have been felled by the disease as of Thursday, according to data compiled by the Johns Hopkins Coronavirus Resource Center.

A new study shows that the West Antarctic Peninsula is experiencing some of the most rapid climate change on Earth, featuring dramatic increases in temperatures, retreats in glaciers and declines in sea ice. The Southern Ocean absorbs nearly half of the carbon dioxide -- the key greenhouse gas linked to climate change -- that is absorbed by all the world's oceans. The study tapped an unprecedented 25 years of oceanographic measurements in the Southern Ocean and highlights the need for more monitoring in the region. The research revealed that carbon dioxide absorption by surface waters off the West Antarctic Peninsula is linked to the stability of the upper ocean, along with the amount and type of algae present. A stable upper ocean provides algae with ideal growing conditions. During photosynthesis, algae remove carbon dioxide from the surface ocean, which in turn draws carbon dioxide out of the atmosphere. From 1993 to 2017, changes in sea ice dynamics off the West Antarctic Peninsula stabilized the upper ocean, resulting in greater algal concentrations and a shift in the mix of algal species. That's led to a nearly five-fold increase in carbon dioxide absorption during the summertime. The research also found a strong north-south difference in the trend of carbon dioxide absorption. The southern portion of the peninsula, which to date has been less impacted by climate change, experienced the most dramatic increase in carbon dioxide absorption, demonstrating the poleward progression of climate change in the region.

A new Spanish study has highlighted current developments in the tourism sector that have significant implications for water supply and demand, but are barely addressed in recent land use policies. The findings indicate that any tourist destination that is to follow the ???quality tourist??? model will have an increased water demand in domestic residential areas, which is one of the biggest threats to sustainable water management.

The amount of land and ocean that a country uses in order to produce food and other commodities, or its land or ocean ‘footprint’, increases by over a third for each doubling of income, new research shows. Thus, as nations become richer, and lifestyles become more affluent, pressure on natural resources increases.

Promoting the personal benefits of sustainable consumption, such as more free time and less stress, could play an important role in encouraging more sustainable living, according to a recent study. The researchers interviewed people who lived greener lifestyles and found that self-interest influenced their decision to consume less and buy sustainable products.

Providing information to consumers on the environmental and social impacts of their food purchases could help change their consumption choices, research from Norway suggests. In a psychological study, researchers noted an increase in the number of organic and fair trade products bought per week when participating consumers were informed of the products’ benefits for the environment and the wellbeing of producers.

A recent study investigates the factors that affect a farmer’s decision to convert to organic farming in Latvia and Estonia. A combination of social factors, such as peer pressure, and economic influences, such as subsidies, were found to be more important than either factor individually.

Reindeer herding has a long history in the Arctic, but climate change and industrial activity are bringing this important economic and cultural tradition to breaking point. In a unique initiative, reindeer herders across the Arctic are leading an international team of scientists in using modern technology to adapt to global change and empower indigenous communities.

To support the move towards a circular economy, in which resources are kept in use for as long as possible to minimise waste, there is great potential for the bioeconomy — those parts of the economy linked to the use of renewable biological resources — to adopt innovative business models and practices, says a new study. However, the study found that bioeconomy businesses instead perceive the circular economy in terms of well-established practices, such as recycling.

A new analysis of greenhouse gas (GHG) emissions from Swiss household consumption reveals a large difference between the best and worst households – which range between the equivalent of 5 to 17 tons of CO2 per capita per year. It suggests GHG reductions are possible if more households adopt similar consumption patterns to those with the lowest emissions.

Dire messages about the impact of global warming may increase scepticism because they contradict a commonly held belief that the world is a just and orderly place. This is the conclusion of new psychological research which investigated the reaction of individuals to messages about global warming.

As wind power becomes more important in the energy mix, so too does the need to manage its variability. A new study has reviewed the options and indicates that, although state-of-the art technologies exist to maximise gains from wind power, they need proper and insightful management.

Vehicle fuel economy has markedly improved, but there are other factors that influence fuel consumption and transport emissions, according to new research on the EU, USA and Japan. Changes in vehicle size and power also play a role indicating that, if fuel prices do not keep rising, policy focus may need to shift to managing vehicle use.

Climate change may increase the risk of outbreaks of infectious diseases, such as salmonella or tick-borne encephalitis. A new study has outlined five main steps in assessing policies to ensure that they can respond effectively to this challenge and highlights the importance of involving stakeholders at every stage of policy assessment.

Although low-income households consume less energy than wealthier households, they are still keen to learn how to save energy, for both economic and environmental reasons. This is the conclusion of a recent Swedish study which explored the energy-related behaviour of residents on low incomes. It provides insights which could help inform energy-awareness campaigns targeted at this section of the population.

Science not communicated is said to be science not done, but journalists’ portrayal of scientific findings can sometimes have a negative impact on public perceptions of science and even create false controversy. This study examined how presenting opposing scientific viewpoints affects public perceptions of environmental risk.

Restaurants can influence consumer food choices by offering climate-friendly meals on their menus, a recent study concludes. In a trial at Finnish restaurants, customers and staff were receptive to selecting meals based on the carbon footprints of their ingredients. Appearance, taste and healthiness were priority factors in consumers’ choices. The research highlights the importance of planning communication strategies and the need for a carbon footprint food database.

The solar energy market is hampered by multiple barriers to adoption in the EU and worldwide, according to a new review. Researchers from Sweden and Spain found that lack of government commitment as well as various sociotechnical, management and economic barriers prevent photovoltaic technologies from being more readily adopted.

A recent study investigated the environmental impact of the disposal of construction waste in Catalonia, Spain. The study suggests that the best options are to recycle construction waste where possible, incinerate the rest and landfill when there is no other option. These findings are in line with the waste hierarchy specified in the Waste Framework Directive.

Biodegradable plastics that break down in the environment can be used instead of traditional plastics to reduce the problem of plastic waste disposal. A new study highlights large differences in the rates of decomposition of these polymers, which can affect decisions on disposal methods.

Eco-innovations which help prevent the production of waste are explored in a recent German study. It considers the drivers and barriers to the uptake of material efficiency measures in businesses, green procurement and product leasing schemes.

A recent survey of Dutch mobile phone owners has identified why some consumers buy refurbished mobile phones while others buy new ones. Some consumers perceived refurbished phones to be inferior, which was a major barrier to their purchase. The study’s authors make a number of recommendations to increase consumer uptake of refurbished mobile phones, including promoting the financial and environmental benefits and offering warranties.

Scientists have tested the behaviour of biodegradable plastics in managed composting and anaerobic conditions, as well as under simulated environmental conditions, such as in seawater or soil. This study found that blending different types of biodegradable plastics may open up new opportunities in relation to their end-of-life treatment — notably the potential to make one of the world’s best-selling biodegradable plastics, polyactic acid (PLA), home-compostable by blending it with another polymer (polycaprolactone — PCL). However, the researchers were also concerned that most materials tested could still cause plastic pollution as they failed to biodegrade sufficiently — and, in some cases, not at all, in particular, in soil and the marine environment.

Electricity consumption fell by 22–27% in low-income households participating in an energy-efficiency programme in Cyprus, France, Malta and Spain, reports a new study. Participants were provided with a range of tools and information to help them curb their energy use, including smart meters and customised reports. The results confirm the value of tailoring information to specific demographic groups.

Interactions between population growth, consumption and the use of natural products and services have created an unsustainable pressure on the environment. New research has provided a detailed investigation into the relationships between these three trends, providing insight into how to alleviate these pressures. It concludes they cannot be addressed by market mechanisms or technological advances alone.

Climate change will lead to an increased risk of flooding and huge economic losses if countries do not invest in appropriate adaptation measures, according to a new study. The research estimates the risks posed by flooding to cities around the world and the associated economic losses in 2005 and 2050, and suggests that flood protection must be increased to maintain the same level of risk to coastal cities.

An inventory of carbon footprints has been developed for 177 regions across 27 EU Member States. The map is the first to quantify greenhouse gas emissions associated with household consumption across the EU. It reveals significant regional differences based on income, household size and urban versus rural living.

A new analysis of waste recycling systems in Portugal highlights where kerbside (edge of pavement) collection systems could be optimised, to decrease their environmental impact. In this case, researchers found that the kerbside system was less favourable economically and environmentally due to more packaging and more fuel consumption per tonne of waste, compared to a system where recyclable materials are deposited by residents in large containers. But the researchers suggest that measures such as re-usable boxes and efficient collection routes could help to mitigate the impact of kerbside collection. While there is an environmental impact from waste collection, processing and disposal, this study only focused on the collection phase.
