Hong Kong Red Cross tightens female blood donor rules for first time in 30 years
The Hong Kong Red Cross has tightened the haemoglobin requirement for female blood donors for the first time in 30 years, as the number who failed to meet the threshold and were turned away dropped nearly 75 per cent in a decade.
Dr Lee Cheuk-kwong, chief executive and medical director of the Hong Kong Red Cross Blood Transfusion Service, said on Tuesday that, effective from May 27, the haemoglobin threshold for female blood donors would be raised from a range of 11.5-12 grams per decilitre, to between 12g/dl and 16.5g/dl.
The requirement for male donors will remain unchanged.
The decision was made after a considerable reduction in the number of blood donors rejected for insufficient haemoglobin, from nearly 40,000 in 2015 to 10,000 last year.
'We notice that there is a significant improvement in haemoglobin levels among the regular donor population. Part of that is related to our education and awareness programmes, which have been impactful for more than 10 years,' Lee said.
While about 10 out of 70 people are currently rejected every day due to insufficient haemoglobin, Lee estimated that around 10 more would be turned away daily for the same reason under the raised threshold.
He also noted that other reasons for rejection included overseas travel, taking prescribed medication, and having the flu.

What next for He Jiankui, the human gene editor locked in limbo?
He Jiankui looked a little tired and worn as he contemplated his future. With no home and no institution to host his research, the 41-year-old biophysicist and self-proclaimed 'pioneer of gene editing ' was weighing up what to do next while staying at an upmarket hotel in Beijing late last month. He, who caused a global uproar in 2018 with his announcement of the world's first gene-edited babies, planned to move to the United States to continue his research into gene-editing embryos to combat diseases such as Alzheimer's and cancer. 'My new lab in Austin, Texas is being prepared and I'll be settling down there,' he said. But with his wife barred from entering China and He banned from leaving it, those plans were in disarray. Nevertheless, the scientist was unbowed and determined to continue the work he had started.

Chinese brain implant reaches landmark clinical trial with operation on amputee
China has become the second country in the world to advance invasive brain-computer interface technology to a human trial, state broadcaster CCTV reported on Saturday. Advertisement The trial is on a 37-year-old man who had to have all of his limbs amputated after a high-voltage electrical accident more than a decade ago. In March, researchers implanted a device roughly the size of a coin and a series of electrodes into the man's brain. A few weeks later, he was able to control a cursor on an electronic device, enabling him to play chess and video games, and perform computer operations at a near-normal level of proficiency, according to the report. The researchers plan to conduct a series of small-scale trials on patients with paralysis or the nervous system disease ALS this year, followed by trials on up to 40 patients in 2026. The trials are being led by the Chinese Academy of Sciences' Centre for Excellence in Brain Science and Intelligence Technology, Huashan Hospital affiliated with Fudan University in Shanghai, and industry partners.

Anti-smoking stand of tobacco tycoon lives on in Hong Kong
It is not that unusual for well-known people to become public anti-smoking converts after being diagnosed with diseases related to tobacco use. An example was tycoon Charles Ho Tsu-kwok, who died this week aged 75, months after revealing he had lung cancer. Ho was involved in national and local affairs as a standing committee member of China's top political advisory body, the Chinese People's Political Consultative Conference (CPPCC), and as a former owner of Sing Tao News Corporation. But what really set him apart as the anti-smoker he became was that he inherited a tobacco empire from his grandfather, Ho Ying-chie, founder of the Hong Kong Tobacco Company. Indeed, Ho was until late in life a staunch advocate of smokers' rights in the face of incontrovertible evidence of the deadly health risks. He once said 'one has freedom in deciding whether to smoke' and that death was a 'personal matter'. The public switch to anti-smoker and the admission he had changed his mind was not out of character for someone with strong views. Former chief executive and CPPCC vice-chairman Leung Chun-ying can attest to that. Known for his outspoken comments on politics, Ho attacked Leung during the chief executive race in 2012, questioning his ability to govern, which prompted Leung to accuse Sing Tao News Corp of running a smear campaign. But Leung said the pair got along afterwards, with the tycoon being a frequent guest at Government House and a source of interesting insights. The public reconciliation of Ho with anti-smoking health minister Lo Chung-mau, whom he once described as 'like a drone, monitoring the whereabouts of smokers', was more personal. It came after his cancer diagnosis. The pair appeared on television urging viewers to quit smoking. Ho said the strain of chemotherapy and radiotherapy had caused him to change his mind, and he thanked Lo for his campaigns on the issue. Lo said Ho had bravely shared his experience with the public, raising awareness of the dangers of smoking. Chief Executive John Lee Ka-chiu paid tribute to the contributions of Ho to the media, national affairs and the city's development. But it is the anti-smoking message of a tobacco tycoon that may make the biggest difference.
