Telehealth Is The Future But May Also Be Healthcare Security’s Achilles' Heel

Everything changed overnight for telehealth at the onset of Covid-19. We went from a small footprint to telehealth becoming one of the most common ways Americans access care. According to the Department of Health and Human Services, nearly half of Medicare primary care visits were telehealth visits in April 2020, compared to 0.1% in February. Waiting weeks to months for a 15- minute physician exam is no longer acceptable for many when you can just set up a quick telehealth conference. However, with widespread healthcare breaches making news, such as the recent suspected ransomware hack on United Health Services, security executives should be on guard because the rise of telehealth has provided new entry points for hackers to exploit.

How technology can help reduce our impact on the planet

All around the globe, people are facing the question of how to grow and thrive with fewer resources. Urban population growth is a major factor, as it’s estimated that by 2030 almost 60 percent of our global population will live in cities. This urban migration is felt even more acutely in Europe, where more than 80 percent of us are predicted to live in towns by 2050.

[…]

Consider the following statements, then choose the correct alternative:

I - People are worried about not having enough provision in the future.
II - In ten years, more than a half of the world population will be living in urban areas.
III - In2050,it’s probable that 4/5 oftheworldpopulation will be living in urban areas.

When my family first moved to North Carolina, we lived in a rented house three blocks from the school where I would begin the third grade. My mother made friends with one of the neighbors, but one seemed enough for her. Within a year we would move again and, as she explained, there wasn't much point in getting too close to people we would have to say good-bye to. Our next house was less than a mile away, and the short journey would hardly merit tears or even good- byes, for that matter. It was more of a 'see you later” situation, but still I adopted my mother's attitude, as it allowed me to pretend that not making friends was a conscious choice. I could if I wanted to. It just wasn't the right time.

Back in New York State, we had lived in the country, with no sidewalks or streetlights; you could leave the house and still be alone. But here, when you looked out the window, you saw other houses, and people inside those houses. I hoped that in walking around after dark I might witness a murder, but for the most part our neighbors just sat in their living rooms, watching TV. The only place that seemed truly different was owned by a man named Mr. Tomkey, who did not believe in television [...].

To say that you did not believe in television was different from saying that you did not care for it. Belief implied that television had a master plan and that you were against it. It also suggested that you thought too much. When my mother reported that Mr. Tornkey did not believe in television, my father said, *Well, good for him. I don't know that I believe in it, either”. “That's exactly how I feel” my mother said, and then my parents watched the news, and
whatever came on after the news.

Can exercise help us shed pounds? An interesting new study involving overweight men and women found that working out can help us lose weight, in part by remodeling appetite hormones. But to benefit, the study suggests, we most likely have to exercise a lot — burning at least 3,000 calories a week. In the study, that meant working out six days a week for up to an hour, or around 300 minutes a week.

For the new study, researchers gathered a group of 44 sedentary, overweight men and women, checked their body compositions, and asked half of them to start exercising twice a week, for at least 90 minutes, until they had burned about 750 calories a session, or 1,500 for the week. The rest of the volunteers began exercising six times a week for about 40 to 60 minutes, burning close to 500 calories a session, for a weekly total of about 3,000 a week.

Interestingly, the researchers did uncover one unexpected difference between the groups. Those burning about 3,000 calories a week showed changes now in their bodies’ levels of leptin, an appetite hormone that can reduce appetite. These alterations suggested that exercise had increased the exercisers’ sensitivity to the hormone, enabling them to better regulate their desire to eat. There were no comparable hormonal changes in the men and women working out less.

Why do we buy into the 'cult' of overwork?

By Bryan Lufkin, 9th May 2021

Although many of us associate overly ambitious workaholism with the 1980s and the finance industry, the tendency to devote ourselves to work and glamourize long-hours culture remains as pervasive as ever. In fact, it is expanding into more sectors and professions, in slightly different packaging. Overwork isn't a phenomenon exclusive to Silicon Valley or Wall Street. People work long hours all over the world, for many different reasons

In Japan, a culture of overwork can be traced back to the 1950s, when the government pushed hard for the country to be rebuilt quickly after World War Two. In Arab League countries, burnout is high among medical professionals, possibly because its 22 members are developing nations with overburdened healthcare systems, studies suggest. Reasons for overwork also depend on industry. Some of the earliest researchers on burnout in the 1970s asserted that many people in jobs geared toward helping others, like employees in clinics or crisis-intervention centers, tended to work long hours that led to emotional and physical exhaustion – a trend which is shown up in the pandemic, too. But millions of us overwork because somehow, we think it’s exciting – a status symbol that puts us on the path to success, whether we define that by wealth or an Instagram post that makes it seem like we're living a dream life with a dream job. Romanticization of work seems to be an especially common practice among "knowledge workers" in the middle and upper classes. In 2014, the New Yorker called this devotion to overwork "a cult".

According to Anat Lechner, clinical associate professor of management at New York University. "We glorify the lifestyle, and the lifestyle is: you breathe something, you sleep with something, you wake up and work on it all day long, then you go to sleep. Again, and again and again."

One of the abiding images of any virus outbreak is people in surgical masks. Using them to prevent infection is popular in many countries around the world, most notably China during the current coronavirus outbreak where they are also worn to protect against high pollution levels.

Virologists are sceptical about their effectiveness against airborne viruses. But there is some evidence to suggest the masks can help prevent hand-to-mouth transmissions.

Dr David Carrington, of St George’s, University of London, told BBC News “routine surgical masks for the public are not an effective protection against viruses or bacteria carried in the air”, which was how “most viruses” were transmitted, because they were too loose, had no air filter and left the eyes exposed. But they could help lower the risk of contracting a virus through the “splash” from a sneeze or a cough and provide some protection against hand-to-mouth transmissions.

Jonathan Ball, professor of molecular virology at the University of Nottingham, said: “In one well controlled study in a hospital setting, the face mask was as good at preventing influenza infection as a purpose-made respirator.”

Respirators, which tend to feature a specialised air filter, are specifically designed to protect against potentially hazardous airborne particles.

“However, when you move to studies looking at their effectiveness in the general population, the data is less compelling - it’s quite a challenge to keep a mask on for prolonged periods of time,” professor Ball added.

Dr Connor Bamford, of the Wellcome-Wolfson Institute for Experimental Medicine, at Queen’s University Belfast, said “implementing simple hygiene measures” was more effective. “Covering your mouth while sneezing, washing your hands, and not putting your hands to your mouth before washing them, could help limit the risk of catching any respiratory virus,” he said.

The aliens among us

Humans think of themselves as the world’s apex predators. Hence the silence of sabre-tooth tigers, the absence of moas from New Zealand and the long list of endangered megafauna. But sars-cov-2 shows how people can also end up as prey. Viruses have caused a litany of modern pandemics, from Covid-19, to hiv/aids to the influenza outbreak in 1918-20, which killed many more people than the first world war. Before that, the colonisation of the Americas by Europeans was abetted – and perhaps made possible – by epidemics of smallpox, measles and influenza brought unwittingly by the invaders, which annihilated many of the original inhabitants.
