Doctors warn against over-medicalising menopause after UK criticism

Posted on by

Seeing natural event as hormone deficiency requiring treatment could increase women’s anxiety, say medics

Doctors have hit back at critics saying they are failing menopausal women, and said that treating menopause as a hormone deficiency that requires medical treatment could fuel negative expectations and make matters worse.

Writing in the British Medical Journal they said there was an urgent need for a more realistic and balanced narrative which actively challenges the idea that menopause is synonymous with an inevitable decline in women’s health and wellbeing, and called for continued efforts to improve awareness about the symptoms and how to deal with them.

How cannabis-fed chickens may help cut Thai farmers’ antibiotic use

Posted on by

Scientists observed fewer cases of avian bronchitis and superior meat after chickens given cannabis

It all began when Ong-ard Panyachatiraksa, a farm owner in the north of Thailand who is licensed to grow medicinal cannabis, was wondering what to do with the many excess leaves he had amassed. He asked: could his brood of chickens benefit from the leftovers?

Academics at Chiang Mai University were also curious. Since last January they have studied 1,000 chickens at Ong-ard’s Pethlanna organic farm, in Lampang, to see how the animals responded when cannabis was mixed into their feed or water.

The results are promising and suggest that cannabis could help reduce farmers’ dependence on antibiotics, according to Chompunut Lumsangkul, an assistant professor at Chiang Mai University’s department of animal and aquatic sciences, who led the study.

Improved disease control in public buildings ‘could save UK billions a year’

Posted on by

Measures such as improved ventilation would boost economy by helping prevent ill health, says report

Mandating improved ventilation and other forms of disease control in public buildings could save the UK economy billions of pounds each year through the prevention of ill health and its societal impacts, according to a report.

It is the first study to comprehensively evaluate the health, social and economic costs of airborne infections, including Covid. Even without a pandemic, seasonal respiratory diseases cost the UK about £8bn a year in disruption and sick days, said the report by the Royal Academy of Engineering and the Chartered Institution of Building Services Engineers. In the event of another severe pandemic within the next 60 years, the societal cost could be as high as £23bn a year.

Researcher says proboscis monkey may have mated with silver langur when unable to reach female of own species

The emergence of a “mystery monkey”, believed to be a rare hybrid of two distantly related primates, highlights the importance of protecting habit connectivity, according to a researcher who studied the animal.

The female monkey first attracted attention in 2017, when photographs taken of it along the Kinabatangan River in Sabah, Malaysia, were uploaded to social media wildlife photography groups.

China calls theory that Covid originated in Chinese lab ‘politically motivated lie’

WHO report has said origins of virus are still unknown and recommended further investigation

China has repeated its assertion the theory that the Covid-19 pandemic began with a leak from a Chinese laboratory is “a politically motivated lie”, after the World Health Organization (WHO) recommended continued investigations this week.

“The lab leak theory is totally a lie concocted by anti-China forces for political purposes, which has nothing to do with science,” the Chinese foreign ministry spokesperson Zhao Lijian said at a daily briefing on Friday.

Xi Jinping says ‘persistence is victory’ as Covid restrictions return to Shanghai and Beijing

Both cities back on high alert, with new lockdowns in Shanghai , and the shutdown of entertainment venues in Beijing

Xi Jinping has reiterated China’s commitment to zero-Covid, declaring “persistence is victory”, as Shanghai and Beijing were hit with new lockdowns, shutdowns, and mass testing drives just a week after the cities celebrated the easing of restrictions.

In response to China’s worst outbreak of the pandemic, Shanghai spent months under an arduous and strict citywide lockdown, while Beijing authorities imposed localised lockdowns, venue and public transport shutdowns, and work-from-home orders. In the last week both had begun easing restrictions, with authorities praising the containment of the community outbreaks of the Omicron variant.

Scientists make ‘slightly sweaty’ robot finger with living skin

Japanese innovation thought to have potential to ‘build a new relationship between humans and robots’

Japanese scientists have developed a “slightly sweaty” robotic finger covered in living skin in an advance they say brings truly human-like robots a step closer.

The finger, which was shown to be able to heal itself, is seen as an impressive technical feat that blurs the line between living flesh and machine. But scientists were divided on whether people would warm to its lifelike anatomy or find it creepy.

65,000 year-old ‘Swiss Army knife’ proves ancient humans shared knowledge, research says

The prehistoric artefacts, all made to a similar shape and template, are found in enormous numbers across southern Africa across vast distances

A 65,000-year-old tool – a kind of ancient Swiss Army knife – found across southern Africa has provided scientists with proof that the ancestors of modern homo sapiens were communicating with each other.

In a world first, a team of international scientists have found early humans across the continent made the stone tool in exactly the same shape, using the same template, showing that they shared knowledge with each other.

Japan to let in foreign tourists, but only if masked and accompanied by chaperone

Visitors from select countries will be allowed to return to Japan from Friday but will only be allowed to travel under strict conditions

Foreign tourists visiting Japan will be required to wear masks and spend their entire stay chaperoned by local guides, as the country prepares to open up to international travellers after two years of Covid-19 border restrictions.

People who have waited patiently for the chance to visit Japan, which imposed some of the toughest travel restrictions during the pandemic, will also have to take out private medical insurance in case they contract the virus, the government said this week.

Gel that repairs heart attack damage could improve health of millions

Injectable, biodegradable technology developed by UK team works as a scaffold to help new tissue grow

British researchers have developed a biodegradable gel to repair damage caused by a heart attack in a breakthrough that could improve the health of millions of survivors worldwide.

There are more than 100,000 hospital admissions every year due to heart attacks in the UK alone – one every five minutes. Medical advances mean more people than ever before survive, with 1.4 million Britons alive today after experiencing a heart attack. But hearts have a very limited ability to regenerate, meaning survivors are left at risk of heart failure and other health problems.

Three jabs best for preventing Covid infections, global analysis finds

Number of doses, not vaccine combinations, key to boosting immunity, according to largest study of its kind

Three doses of the same Covid-19 vaccine or a combination of jabs work equally well in preventing infections, according to the largest study of its kind.

While the effectiveness of individual coronavirus vaccines is well known, the evidence around combinations of jabs has been less clear, especially for particular groups such as older people and those who are immunocompromised.

Report outlines ‘research waste’ that occurred during the pandemic, with weakly designed trials exposing millions to unproven treatments

Government efforts to focus NHS resources on a smaller number of well-designed clinical trials could inadvertently be contributing to a backlog of stalled medical research, and result in some important trials being scrapped, researchers say.

Their warning comes as a report outlines the scale of “research waste” that has occurred during the pandemic, with rampant duplication of scientific efforts and weakly designed clinical trials exposing millions of patients to unproven treatments, with little scientific benefit.
