The once-futuristic idea of sequencing every newborn child’s DNA to screen for genes that could shape their future health is being put to two major tests. The United Kingdom this week announced plans to sequence the genomes(基因组)of 100, 000 newborns for about 200 rare genetic diseases starting next year. In New York City, a similar project
The goal is to catch treatable diseases that standard newborn screening cannot detect.
But sequencing the full genomes of new-borns raises a host of ethical questions, including

3 . Imagine a future where science has created your twin. Not a flesh-and-blood twin, but one that recreates your flesh and blood, your bones, your heart, your brain — your whole body, in fact — as an extremely complicated computer model.
Your doctors can use this digital twin to work out how you will respond to a particular drug or medical procedure. They can even look further into the future, creating a “healthcast”, to forecast what diseases might happen to you or how your lifestyle will affect your health as you age. It is the ultimate in personalized medicine. This is the bold vision set out in Virtual You: How building your digital twin will revolutionize medicine and change your life by Peter Coveney, director of the Centre for Computational Science, and Roger Highfield, science director of the Science Museum Group, UK.
Digital twins are already in widespread use in industries such as civil engineering. But these model systems are much simpler than the complex human body. Imagine all the parts that come together to make you work: from the 3 billion letters of your genome (基因组), the numerous molecules (分子) that make up your cells, the trillions of cells building your tissues and organs, and the environment having its input too. Now, imagine trying to create a model of this that is made to each unique individual and that predicts the changes that will take place over a lifetime. This is easier said than done. Changes in the systems biologists want to describe are usually different from what mathematicians describe as “non-linear” (非线性的). Another complication is “emergence”: where the whole of a system is greater than the sum of its parts. This complexity challenges mathematics and pushes computing to the limit too.
But getting to the next level — a whole human individual — is going to require yet more data and a revolution in computing technology far beyond what is currently possible. Whether we will get there is an open question, but Virtual You shows us what scientists from different fields can achieve when they all work together.

4 . Medical artificial intelligence (AI) can perform with expert-level accuracy and deliver cost-effective care. IBM’s Watson diagnoses (诊断) heart disease better than cardiologists (心脏病专家) do. Chatbots give better medical advice to patients in place of nurses. Some forecast that medical AI will enter 90% of hospitals and replace as much as 80% of what doctors currently do. Yet, as our recent research suggests, patients show a strong resistance to medical AI.
The reason, we found, is not the belief that AI provides lower care. Nor is it that patients think that AI is more costly or less informative. Rather, resistance to medical AI seems to come from a belief that AI does not take into account one’s specific circumstances. People view themselves as unique. By contrast, they think medical care delivered by AI providers is suited to treat an average patient but unsuitable to account for the unique circumstances that apply to an individual. No wonder that medical AI providers are given a cold welcome.
There are a number of steps that care providers can take to overcome patients’ resistance to medical AI. For example, if an AI provider is capable of tailoring its recommendation for whether to have a surgery to each patient’s unique characteristics and medical history, patients would be likely to follow the treatment recommendations of the AI provider. In addition, health care providers could also deliver individualized health care by explaining how the algorithms (算法) work and sharing patients’ reviews with the media. Having a physician confirm the recommendation of an AI provider should make people more willing to accept AI-based care. People are comfortable using medical AI if a physician remains in charge of the ultimate decision.
AI-based health care technologies are being developed and employed at an impressive rate, providing better medical services for the patients. But harnessing the full potential of them will require that we first overcome patients’ doubt of having an algorithm, rather than a person making decisions about their care.

5 . When I was in nursing school, I had to focus more on my studies than other aspects of life, and learn so much in a short amount of time. However, the clinical experience of nursing school allowed me to have the opportunity to put what I learned in my classes and readings into action.
One of my favorite experiences during my clinical training was when I had a patient who was first starting chemotherapy (化疗). My nursing instructor Marie told me that patients often experience an anaphylactic (过敏性的) reaction to the medicine when they first start chemotherapy, so it is important to give the medicine at a slower rate. Marie said that if we had a patient who reacted to the medicine, we should stop running the chemotherapy, check the patient’s blood pressure, and then give the appropriate medicine from the emergency kit.
When I checked my patient a couple of minutes after starting his chemotherapy, I asked him questions related to an anaphylactic reaction. I also noticed his face was getting a little red and he looked short of breath. He mentioned having lower back pain, so I immediately stopped the chemotherapy, started taking his blood pressure, and reported it to Marie. His blood pressure was within his normal limits, so we gave him Benadryl via his IV. The Benadryl helped the patient, and we had the Benadryl running when we started his chemotherapy again, but at a slower rate. This time the patient did not have an anaphylactic reaction, and tolerated his chemotherapy well.
This experience taught me how important it is to assess your patient and to teach your patient beforehand about the reaction the patient could have due to the medicine. Marie and I taught our patient about the reactions he could have due to the chemotherapy; due to our teaching, our patient recognized his symptoms and was able to know that what he was experiencing was an expected reaction. During the clinical training, I had many experiences where I had to think on my feet and conduct nursing care quickly. These experiences taught me a lot about how to be a nurse and emphasized the importance of conducting proper patient care.

6 . Twice every month, Miranda Sam, a 66-year-old Ghanaian, visited the China Traditional Herbal Hospital, a private herbal facility at Pokuase, a suburb of the Ghanaian capital, for treatment.
“I was squeezing lemons, and when I finished, I could not get up or even move my legs, so I went to the hospital and did an X-ray examination, but they saw nothing. Meanwhile, I could not walk and was in a wheelchair,” the retired worker said. Hence Miranda decided to visit the herbal facility. “On two occasions, I had to do acupuncture(针灸), and I have found great relief. Now I walk unaided, so I keep coming for treatment,” she said.
As Traditional Chinese Medicine (TCM) is gaining popularity in Ghana, many acupuncture clinics run by Chinese doctors pop up in the country. However, the China Traditional Herbal Hospital was established by 52-year-old Ghanaian business owner Bediako, after his fruitful encounter with the effects of TCM in 2012. With the help of a Chinese lady, Bediako set up a small clinic specializing in TCM. Years on, the facility has subsequently grown into a bigger herbal hospital. The hospital treats patients with a combination of local and Chinese herbal formulas. It supports this with the application of traditional Chinese medical methods.
Strokes(中风) account for 1.3 percent of all hospital admissions in Ghana, and 6.3 percent of all hospital deaths. But Bediako is confident that as more people with these conditions turn to the natural methods of healing, the pain and death rates would subside. “A gentleman was brought here three weeks ago, who could not sit, stand, or walk. He was first taken through acupuncture. I observed him on camera 30 minutes later, squatting(蹲), standing, and walking. You come here with your pain but will leave with a smile. That is our feature,” he said.
The hospital has started a second facility in Ashaiman near the capital, with plans to open other branches across the country to meet the growing demand.

7 . Paintings and sculptures can be a feast for the eyes of visitors to art museums, but today their viewing is also an unconventional treatment for people with mental illness.
Last month. a group of Canadian doctors started to write a new kind of prescription (处方), which gives patients free access to the Montreal Museum of Fine Arts (MMFA). There, they will have a “relaxing. revitalizing experience” looking at the museum’s collection.
Nathalie Bondil. the museum’s director general. believes that being in contact with culture and arts can help with wellbeing. “In the 21st century, culture will be what physical activity was for health in the 20th century.” she said.
Each prescription will allow not only the patients but also their families or friends to go with them. In the museum. the visitor can appreciate the artworks, and take part in a wide range of activities including drawing, sewing (缝纫) and making a sculpture with recycled materials.
The new treatment is said to be the first of its kind in the world. But there’s increasing evidence that the display of visual art, especially art depicting (描绘) nature, can have positive effects on people with depression, anxiety and self-respect problems.
In 2017, the UK’s All Party Parliamentary Group on Arts, Health and Wellbeing
(APPGAHW) also released a report stating that “the time has come to recognize the powerful contribution the arts can make to our health and wellbeing”.
Is it possible for art to improve overall health? We may not know the answer yet. But one thing is certain, more and more people today are persuaded by the idea that “art is good medicine”.
