EXCLUSIVE All the times China has smuggled terrifying pathogens into the US to kill Americans or destabilize the nation
Dangerous Chinese bioweapons and pathogens are increasingly being smuggled into the US to sicken Americans, experts warn.
In the past several years, US Customs officials have seized hundreds of suspicious packages and vials of blood, animal parts and even cancer cells from Chinese officials arriving on American soil.

Statins can reduce sepsis deaths, study suggests
People who are critically ill with sepsis may be more likely to survive if they are given statins, a new study suggests. Researchers wanted to explore whether the cholesterol-busting drugs may bring additional benefits for patients. Advertisement The new study examined information on sepsis patients who received statins during a stint in intensive care and compared it with patients in a similar situation who did not receive statins. Some 14.3 per cent of 6,000 sepsis patients who were given statins died within 28 days. This is compared with 23.4 per cent of 6,000 patients who did not receive statin therapy. The research team from China said that this equates to a 39 per cent reduced risk of death within a month. Advertisement The research, based on data from thousands of patients at a hospital in Israel between 2008 and 2019, also found that 7.4 per cent of statin patients died while in the intensive care unit compared with 13.6 per cent of those who did not receive statins. And during their overall hospital stay, some 11.5 per cent of sepsis patients who were given statins died, compared with 19.1 per cent of sepsis patients who did not take statins. However, it appeared that those who were not prescribed statins had a slightly shorter hospital stay compared with those who did receive them – an average of eight days compared with almost 10 days. 'We found that statin users exhibited decreased 28-day all-cause mortality,' the authors wrote in the journal Frontiers in Immunology. Advertisement Sepsis is a life-threatening reaction to an infection that occurs when the immune system overreacts and starts to damage the body's tissues and organs. In Ireland, about 12,000 people are affected by sepsis every year, according to the HSE. Sepsis experts said that 'anything which might reduce the burden of a condition which claims one in five lives worldwide needs to be rigorously explored' as they called for larger trials to confirm the findings. Statins are known as cholesterol-busting drugs because they can help lower the level of low-density lipoprotein (LDL) cholesterol in the blood. Advertisement But experts said that they also have other benefits, including reducing inflammation and antibacterial effects. The research team called for larger trials to confirm their findings. 'Our large, matched cohort study found that treatment with statins was associated with a 39 per cent lower death rate for critically ill patients with sepsis, when measured over 28 days after hospital admission,' said Dr Caifeng Li, the study's corresponding author and an associate professor at Tianjin Medical University General Hospital in China. 'These results strongly suggest that statins may provide a protective effect and improve clinical outcomes for patients with sepsis.'

Read More Commenting on the study, Dr Ron Daniels, founder and chief executive of the Sepsis Trust, said: 'It has been known for some time that the anti-inflammatory properties of statins confer a survival benefit on those who take them if they develop sepsis. 'Whilst previous studies have failed to show a similar survival benefit in treating people with sepsis with statins, this new study supports calls for a large, multi-country, randomised control trial. 'Anything which might reduce the burden of a condition which claims one in five lives worldwide needs to be rigorously explored.'

Blood test for Alzheimer's could soon be available on the NHS
A new blood test for Alzheimer's disease has been found to accurately detect early symptoms of the illness, according to new research. Experts from the Mayo Clinic in the US examined two proteins in blood plasma – amyloid beta 42/40 and p-tau217 – which are associated with amyloid plaque build-up, a hallmark of Alzheimer's disease, to provide further evidence that blood tests can accurately diagnose dementia. The study, which was carried out on more than 500 people in an outpatient memory clinic, found the blood test was highly accurate, with 95 per cent sensitivity. That means it was 95 per cent accurate in picking up people with memory problems, with very few cases missed. It was also 82 per cent for specificity, meaning it was also highly accurate in ruling out people without dementia. The blood test has already been approved by the Food and Drug Administration regulator in the US. Dr Gregg Day, who led the study in the Alzheimer's and Dementia journal, said the test was as good as more invasive tests currently in use. 'When performed in the outpatient clinical setting, this is similar to the accuracy of cerebrospinal fluid biomarkers of the disease and is much more convenient and cost-effective.' Overall, researchers found that p-tau217 levels were higher in patients with Alzheimer's disease versus those without the disease. Dr Day said the next steps in the research were to evaluate blood-based testing in more diverse patient populations and people with early Alzheimer's who show no cognitive symptoms. Dr Richard Oakley, associate director for research and innovation at the Alzheimer's Society in the UK, said the results 'suggest this test is very accurate' and could be used alongside other tests and observations from a trained health professional. 'While focused on Alzheimer's disease, the test was evaluated in people with other types of dementias too, showing that it may help with differentiate causes of cognitive decline – though more research in diverse groups of individuals and in community-based setting is still needed. 'Currently diagnosis options in the UK are often slow, expensive and can be invasive, meaning thousands miss out on the benefits one can bring. 'It's great to see blood tests like this approved for clinical use in the US – we hope to see the same in the NHS, which is why we're part of the Blood Biomarker Challenge.' The Blood Biomarker Challenge is a multi-million-pound research programme supported by the Alzheimer's Society, Alzheimer's Research UK and the National Institute for Health and Care Research. Its goal is to bring blood tests for dementia diagnosis to the NHS by 2029. Dr Julia Dudley, head of research at Alzheimer's Research UK, said: 'We urgently need to improve how we diagnose dementia and it's great to see international research working towards this goal. 'Blood tests in this study look at p-tau217 and amyloid beta 42/40, and showed the tests offered high accuracy in confirming Alzheimer's disease. 'This study adds to the growing evidence that blood tests can detect the diseases that cause dementia in people with early memory and thinking problems. 'An important point to consider is that people taking part in research don't always reflect the full diversity of those affected by dementia, who might have additional conditions or other characteristics. 'That is why work is needed to understand whether these blood tests work in a real-world setting.'

Alzheimer's blood test ‘can accurately pick up early symptoms'
A new blood test for Alzheimer's disease can accurately detect people with early symptoms, research suggests. Experts from the Mayo Clinic in the US have provided further evidence that blood tests can work to accurately diagnose dementia, by examining two proteins in blood plasma. These proteins – amyloid beta 42/40 and p-tau217 – are associated with amyloid plaque build-up, which is a hallmark of Alzheimer's disease.

'The study is testing blood tests, including p-tau217, in thousands of people from sites across the UK. 'This work will be a crucial part of making diagnosis easier and faster, which will bring us closer to a cure.'
