Current diagnostic method for Barrett’s oesophagus relies on invasive and costly endoscopy
An electronic device that “sniffs” breath may offer a new way to identify people with a condition that can lead to cancer of the oesophagus, researchers have revealed.
Recent figures suggest there are about 9,000 new cases of oesophageal cancer, or cancer of the food pipe, every year in the UK.

China’s president, Xi Jinping, has made his first public appearance in weeks, as some people began to return to work following the lunar new year holiday, which was extended as authorities grappled with the coronavirus outbreak.
Xi, who has been absent from public view as the crisis worsened, visited a neighbourhood in Beijing’s Chaoyang district. The president had his temperature taken and greeted residents and workers, according to a brief video posted by the state broadcaster CCTV.

The death of the whistleblower Chinese doctor Li Wenliang has aroused strong emotions across China. Social media is awash with posts mourning the death of a martyr who tried to raise alarm over the coronavirus but was taken into a police station instead for “spreading false rumours” and “disrupting social order”.
Grief quickly turned into angry demands for free speech. The trending topic “we want freedom of speech”, which attracted millions of views, and links to Do You Hear the People Sing, a song popularised in recent Hong Kong protests, were quickly censored by police.

A drug used to treat people with HIV, the virus that causes Aids, is being trialled in patients in China as a possible therapy against the coronavirus.
News that HIV drugs are being deployed in hospitals, however, has led to panic buying on the black market by people who fear they are ill or are going to get sick. They have been obtaining the drug, Kaletra, from generics companies in India and even from people with HIV in China willing to sell or donate their own stocks.

Global health experts have warned that “hidden” infections make containment of the coronavirus unlikely and raised fears that the rapidly rising caseload of 25,000 people could be the “tip of the iceberg”.
“Hidden” cases – where people with mild symptoms do not seek medical help and so remain untested and unrecorded – combined with the highly contagious nature of the disease mean there could be “vastly more cases” than previously thought, according to Tom Frieden, a former director at the US Centers for Disease Control and Prevention.

On social media this week the insults were flying thick and fast, some tinged with racism, but all with a common theme: how the World Health Organization, and its head, Dr Tedros Adhanom Ghebreyesus, was effectively doing the bidding of the Chinese government in the midst of the Wuhan coronavirus outbreak.
It is a charge that has also been expressed in less offensive terms elsewhere in columns and articles, some of which have focused on whether, in praising China’s response to the deadly Wuhan coronavirus outbreak during a visit to Beijing, Tedros allowed himself to become complicit in China’s flawed handling of the outbreak in its early days?

When the World Health Organization declared the 2019nCoV coronavirus outbreak a global health emergency, it effusively praised China’s response to the outbreak. The WHO issued a statement welcoming the government’s “commitment to transparency”, and the WHO director general, Dr Tedros Adhanom Ghebreyesus, tweeted: “China is actually setting a new standard for outbreak response.”
The WHO is ignoring Chinese government suppression of human rights regarding the outbreak, including severe restrictions on freedom of expression. In turn, Chinese state media are citing the WHO to defend its policies and try to silence criticism of its response to the outbreak, which has included rights violations that could make the situation worse.

It is a novel coronavirus – that is to say, a member of the coronavirus family that has never been encountered before. Like other coronaviruses, it has come from animals. Many of those infected either worked or frequently shopped in the Huanan seafood wholesale market in the centre of the Chinese city, which also sold live and newly slaughtered animals. New and troubling viruses usually originate in animal hosts. Ebola and flu are examples.

Study of nearly 3,000 women suggests body may ‘choose’ not to invest in ovulation
Women who have sex more often are less likely to have an early menopause, according to research that raises the intriguing possibility that lifestyle factors could play a more significant role than previously thought in determining when the menopause occurs.
The study, based on data collected from nearly 3,000 women who were followed for 10 years, found that those who reported engaging in sexual activity weekly were 28% less likely to have experienced menopause at any given age than women who engaged in sexual activity less than monthly.

Human livers from organ donors can now be preserved for a week, researchers have revealed, a dramatic improvement on previous techniques, which could only keep the organs usable for a matter of hours.
The technology could boost the number of livers available for transplantation and offer new approaches to treating diseases such as liver cancer.

The finding that the outbreak of viral pneumonia in China that has struck 59 people may be caused by a coronavirus, the family of viruses behind Sars, which spread to 37 countries in 2003, causing global panic and killing more than 750 people, means that health authorities will be watching closely.
China says the illness is not Sars (severe acute respiratory syndrome), nor Mers (Middle East respiratory syndrome), both of which are caused by coronaviruses, and so far it appears milder than both. Unlike Sars, it does not appear to spread easily between humans and unlike Mers, which has a mortality rate of about 35%, nobody has died.

The global toll of dengue fever is becoming well known, with rising temperatures contributing to severe outbreaks that made 2019 the worst year on record for the disease.
In 1970 only nine countries faced severe dengue outbreaks. But the disease, which is spread by mosquitoes that can only survive in warm temperatures, is now seen in more than 100 countries. There are thought to be 390m infections each year
Continue reading...Many cases blamed on a single individual who appears to have caught virus for second time
Health officials are investigating an alarming spike in Ebola cases in the Democratic Republic of the Congo, with many blamed on a single individual who appears to have contracted the disease for a second time this year.
Amid the struggle to bring the 16-month outbreak under control, the World Health Organization noted an almost 300% increase in cases in the last three weeks, with 17 of 27 linked to a single chain of transmission.

New cases of polio linked to the oral vaccine have been reported in four African countries and more children are now being paralysed by vaccine-derived viruses than those infected by viruses in the wild, according to global health numbers.
The World Health Organization (WHO) and partners identified nine new cases caused by the vaccine in Nigeria, the Democratic Republic of the Congo, Central African Republic and Angola last week. Along with seven other African countries with outbreaks, cases have also been reported in Asia. In Afghanistan and Pakistan polio remains endemic, and in Pakistan officials have been accused of covering up vaccine-related cases.

Doctors have put humans into a state of suspended animation for the first time in a groundbreaking trial that aims to buy more time for surgeons to save seriously injured patients.
The process involves rapidly cooling the brain to less than 10C by replacing the patient’s blood with ice-cold saline solution. Typically the solution is pumped directly into the aorta, the main artery that carries blood away from the heart to the rest of the body.

Researchers have discovered a way to stop rabies from shutting down critical responses in the immune system, a breakthrough that could pave the way for new tools to fight the deadly disease.
Rabies kills almost 60,000 people each year, mostly affecting poor and rural communities.

Two people in China have been diagnosed with plague, the latest cases of a disease more commonly associated with historical catastrophe.
Plague is caused by the bacterium Yersinia pestis and can arise in three forms – a lung infection, known as pneumonic plague; a blood infection, known as septicemic plague; and a form that affects the lymph nodes, called bubonic plague.

Any amount of running is good for you, according to research suggesting it is linked to a similar reduction in the risk of early death no matter how many hours you clock up a week or how fast you go.
According to the World Health Organization, about 3.2 million deaths each year are down to people not doing enough physical activity.
