Anthony Fauci’s diaries take aim at News Corp journalist Sharri Markson’s ‘nonsense’ Covid-19 investigation

Posted on by

US former top health official, who was subpoenaed to appear at a Senate hearing into Covid-19, says Markson’s reporting about virus’s origin ‘does not make any sense’

Dr Anthony Fauci, the US’s chief medical adviser at the start of the pandemic, has described a book by News Corp investigative journalist Sharri Markson backing the “lab leak” theory of Covid-19’s origins as a “bunch of nonsense” in his newly released diaries.

This week, Fauci, 85, was subpoenaed by the Republican senator Rand Paul to appear at a Senate hearing into Covid-19 and his handling of the pandemic.

Exclusive: Research spanning 82 countries finds antibiotic resistance increased in every region between 2004 and 2022

Harry Booth has had a rough run through Australia’s coldest months. The 13-year-old has been in and out of hospital with a range of common chest and urinary tract infections that his doctors find challenging to treat.

Harry was born with kidney failure and began dialysis at six months old, before receiving a kidney transplant from his father at age four. The surgery saved his life but comes with a trade-off: he now needs to take medications that suppress his immune system to prevent his body from rejecting the kidney.

Study suggests even light activity such as ironing could reduce health risks linked to prolonged sedentary behaviour

Sitting for longer than half an hour at a time each day raises the risk of dying from cancer, a study suggests.

Researchers who tracked more than 90,000 people over a decade found that sitting or lying down while awake for more than 30 minutes in one period each day was associated with an increased risk of cancer death. The risk increases for every additional hour of continuous inactivity, the findings suggest.

Lupus patients in England in remission after pioneering NHS trial of GM therapy

Doctors say therapy that genetically modifies person’s T-cells could offer cure for chronic autoimmune disease

Five lupus patients in England are in remission after being treated with a revolutionary therapy that genetically modifies their own cells, in a medical breakthrough that could offer people a cure, doctors have said.

CAR (chimeric antigen receptor) T-cell therapy involves removing a type of white blood cell also called T lymphocytes, which are crucial for hunting out infected or damaged cells, and engineering them to spot and destroy disease. The T-cells are then fed back into the patient via an infusion to reset their immune system.

Hundreds of cases reported in the DRC after USAID has been dismantled and key scientific research canceled

A previously undetected outbreak of Ebola is coursing through parts of central Africa, and the US appears to be doing little to help stop it, after massive cuts to global and domestic public health efforts.

There is no cure and no vaccine for the rare Bundibugyo variant of Ebola, which has caused two outbreaks in recent decades. Health leaders and scientists are now racing to understand where the virus is spreading and attempting to stop it – but the US is notably absent in these efforts.

‘We’re not ready’: US lags on pandemic preparedness after Covid, experts say

Experts say slashed funding and growing misinformation are some of the greatest challenges facing public health

The hantavirus outbreak, while unlikely to spark the next big pandemic, is shining a spotlight on the ways public health has deteriorated in the US: its ability to test for rare diseases, its expertise on outbreak prevention and response, its ability to battle misinformation and restore trust.

“Assuming everything goes well in containing this outbreak, which I hope it does, the takeaway from that should not be ‘we’re fine,’” said Stephanie Psaki, former White House global health security coordinator. “We’re not ready for this type of threat.”

Exclusive: Sperm re-transplant offers hope that boys left infertile by chemotherapy could have biological children one day

In a groundbreaking fertility trial, a man whose testicular tissue was frozen before he underwent chemotherapy as a child to be re-transplanted 16 years later has been able to produce sperm.

It is the first time a transplant of cryopreserved prepubertal testicular tissue has been demonstrated to restore sperm production in an adult patient. The 27-year-old man had the sample frozen when he was 10, before undergoing potent chemotherapy as part of treatment for sickle cell disease.

Results suggest radiotracer maraciclatide can ‘light up’ condition on scan and reduce need for investigative surgery

A non-invasive scan for endometriosis has shown promising results in a trial, boosting hopes for far quicker diagnosis.

The trial, which included 19 women with the condition, suggests that an experimental radiotracer, called maraciclatide, can “light up” endometriosis on a scan. The current need for a surgical investigation is seen as a major obstacle to timely diagnosis, with women in England typically waiting nearly a decade.

People with meniscus tears who underwent surgery had poorer knee function and worse osteoarthritis after 10 years than those who did not

A common knee surgery for cartilage damage does not benefit patients and may lead to worse outcomes, a 10-year trial suggests.

The study tracked outcomes for patients treated for a meniscus tear, who were given a partial meniscectomy, one of the most common orthopaedic surgeries. Their trajectories were compared with patients who had randomly been assigned to receive “sham surgery”, in which no procedure was carried out.
