Common cold antibodies hold clues to COVID-19 behavior; lung scans speed COVID-19 diagnosis in stroke patients

(Reuters) – The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.

Common cold antibodies yield clues to COVID-19 behavior

Among people who were never infected with the new coronavirus, a few adults – and many children – may have antibodies that can neutralize the virus, researchers reported on Friday in Science. Among 302 such adults, 16 (5.3%) had antibodies, likely generated during infections with “common cold” coronaviruses, that reacted to a specific region of the spike protein on the new virus called the S2 subunit. Among 48 children and adolescents, 21 (43.8%) had these antibodies. In test tube experiments, blood serum from both older and younger uninfected individuals with cross-reactive antibodies could neutralize the new coronavirus. That was not the case with serum from study participants who lacked these antibodies. “Together, these findings may help explain higher COVID-19 susceptibility in older people and provide insight into whether pre-established immunity to seasonal coronaviruses offers protection against SARS-CoV-2,” the publishers of the journal said in a statement. The findings also suggest that targeting the S2 subunit on the coronavirus spike protein might be the basis for a drug or vaccine that works on multiple types of coronavirus. (bit.ly/3evCSFB)

Lung CT speeds COVID-19 diagnosis in stroke patients

In emergency-room patients with stroke, lung imaging studies can help detect COVID-19 before results of nasal and throat swab tests come back, researchers say. Stroke can be a sign of COVID-19, but swab results can take days to become available. At three New York City hospitals in March and April, doctors ordered computed tomography angiograms (CTA) on 57 stroke patients within 24 hours of hospital admission, to look for COVID-19-related pneumonia. Thirty patients turned out to have COVID-19, based on their nasal swab results. But the CTA scans, in combination with patients’ symptoms like cough and shortness of breath, allowed for the diagnosis of COVID-19 with 83% accuracy before the swab test results were received. Screening stroke patients for possible COVID-19 based only on symptoms is unreliable, because they may not have symptoms or they might not be able to speak, the researchers point out in their report in the American Heart Association journal Stroke. “Early diagnosis via CT scans has helped our center protect other patients and staff through early isolation, and it has also allowed us to start early supportive care for those suspected of having stroke who are COVID-19 positive,” coauthor Dr. Charles Esenwa of the Montefiore Medical Center said in a news release.

New coronavirus sneaks out of cells “with the trash”

The new coronavirus uses a surprising pathway to exit infected cells and go on to infect others, researchers have discovered. It hijacks a cell structure called the lysosome, which is normally where cellular trash goes to be destroyed. But the virus uses lysosomes as escape hatches, the researchers report in Cell. “To my knowledge coronavirus is one of 2 or 3 viruses to do this, and certainly the only enveloped virus,” said coauthor Nihal Altan-Bonnet of the National Heart Lung and Blood Institute, referring to viruses that have a membrane surrounding their genetic material. “All other enveloped viruses … use other pathways for cell-to-cell spread,” Altan-Bonnet added. These include influenza, hepatitis C, Dengue, Zika, West Nile and Ebola. When lysosomes degrade bacteria and viruses into little pieces, she explained, “these little pieces get presented on the surface of the cell to alert the immune system” to the invaders’ presence. By using the trash disposal system of the cell to get out, the new coronavirus disables the lysosome and disrupts alerting the immune system, she said. “We believe our discovery of the pathway used by coronaviruses to get out of cells will be fundamental to our understanding of how these viruses wreak havoc on our body, in particular our immune system.” (bit.ly/36aBSmr)

On December 1, 2022, the Social Responsibility Report of Chinese Companies in Saudi Arabia was officially launched, which is the first such report released by the Contact Office of Chinese Companies in Saudi Arabia. BGI Genomics projects in the Kingdom have been incorporated into this report.

This event was attended by around 150 representatives of Chinese and Saudi enterprises, Saudi government officials, experts in the field of sustainable development, CCTV, Xinhua News Agency, Saudi Press Agency, Arab News and other media professionals. This Report presents the key projects and best practices of Chinese enterprises to fulfil their social and environmental responsibilities while advancing the Kingdom’s industry development.

Chen Weiqing, the Chinese ambassador to Saudi Arabia, said in his video speech that the Report highlighted Chinese enterprises’ best practices in serving the local community, safe production, green and low-carbon development and promoting local employment. The release of the Report helps Chinese enterprises in the Kingdom to strengthen communication with the local community, laying a stronger foundation for future collaboration.

Epidemic control and accelerating post-COVID 19 recovery

BGI Genomics has been fulfilling its corporate social responsibilities and worked with the Saudi people to fight the COVID-19 epidemic.

In March 2020, Saudi Arabia was hit by the pandemic. The Saudi government decided to adopt BGI Genomics’ Huo-Yan laboratory solution in April 2020. At the forefront of the fight against the epidemic, the company has built six laboratories in Riyadh, Makkah, Madinah, Dammam and Asir within two months, with a total area of nearly 5,000 square meters and a maximum daily testing throughput of 50,000 samples.

By the end of December 2021, BGI Genomics had sent 14 groups of experts, engineers and laboratory technicians to Saudi Arabia, amounting to over 700 people, and tested more than 16 million virus samples, accounting for more than half of the tests conducted during this period. The company has successfully trained over 400 qualified Saudi technicians, and all laboratories have been transferred to local authorities for the operation.

In the post-epidemic era, the Huo-Yan laboratories can continue to make positive contributions to public health, working with local medical institutions and the public health system to make breakthroughs in areas such as reproductive health, tumour prevention and control, and prevention.

Enhancing genomic technology localization and testing capabilities

In July 2022, BGI Almanahil and Tibbiyah Holdings, a wholly owned subsidiary of the Saudi Faisaliah Group, announced a joint venture (JV) to establish an integrated, trans-omics medical testing company specializing in genetic testing.

This JV company will help improve Saudi Arabia’s local clinical and public health testing and manufacturing capabilities, promote the localization of strategic products that have long been imported, contribute to the implementation and realization of the Kingdom’s Vision 2030 roadmap, and significantly enhance local capacity for third-party medical testing services as well as local production of critical medical supplies.

BGI Genomics attaches great importance to fulfilling its corporate social responsibility and has released its social responsibility report for four consecutive years since 2017. Since its establishment, the company has always been guided by the goal of enhancing health outcomes for all, relying on its autonomous multi-omics platform to accelerate technological innovation, promote reproductive health, strengthen tumour prevention and control, and accurately cure infections, and is committed to becoming a global leader in precision medicine and covering the entire public health industry chain.

The company will continue to work together with all stakeholders to contribute to the Kingdom’s Vision 2030 and the Belt and Road Initiative and looks forward to growing with our partners.

Alcohol deaths in the UK rose to record level in 2021

Nearly 10,000 people died from alcohol in 2021.

Published

By

Deaths from alcohol in the UK have risen to their highest level since records began in 2001, according to the latest data from the Office for National Statistics (ONS). In 2021, 9,641 people (14.8 per 100,000) died as a result of alcohol: a rise of 7.4% from 2020.

The leading cause of alcohol-specific deaths (deaths caused by diseases known to be a direct consequence of alcohol) continues to be liver disease. More than three-quarters (78%) of all alcohol deaths in 2021 were attributed to this cause. The remainder of the deaths were due to “mental and behavioural disorders because of the use of alcohol” and “accidental poisoning by, and exposure to, alcohol”.

Although there is no such thing as a safe level of drinking, and many people would feel the health benefits of reducing consumption, most of the risks of developing health problems and dying are skewed towards those who drink the most.

Between 2012 and 2019 alcohol-specific deaths remained relatively stable. It is no coincidence that deaths rose sharply during the first two years of the pandemic: those that were already drinking at harmful levels increased their consumption further during this period. Although liver disease can take years to develop, this process is accelerated when those drinking at harmful levels increase their consumption further.

Other statistics show that unplanned alcohol-related hospital admissions decreased during this period, which may have meant missed opportunities to provide help for those people experiencing problems with alcohol.

Looking beyond the headline figures, there are important differences in various groups within the population. Alcohol-specific deaths were not spread equally. For example, men were twice as likely to die as women. In 2021, 20.1 men per 100,000 died compared with 9.9 women.

Where you live in the UK matters, too, as deaths in Scotland are the highest, followed by Northern Ireland, Wales then and England – although the gap between the nations seems to be narrowing.

In England, deaths are highest in the north-east of England (20.4 per 100,000), which is twice as high as those in London (10.2 per 100,000). Although rates have increased in all regions; for example, there was a rise of 38% in south-west England from 2019 to 2021. This reflects what is already known about the relationship between deprivation and harm from alcohol. There is a two to fivefold higher risk of dying among lower-income groups compared with those from the higher-income groups.

Reflecting the growing trend of young people drinking less than older age groups, it is those aged 50 to 64 that account for most deaths due to liver disease. In 2021, for example, 39 people aged 25 to 29 died from alcohol-related liver disease, compared with 1,326 of those aged 50 to 59. This is related to a greater number of years of drinking but is also a general reflection that when older adults were younger, they tended to drink more than younger people do now.

Addressing harms

So what can be done to begin to address alcohol harms? It has been estimated that almost a quarter of drinkers in the UK drink above the recommended low-risk drinking guidelines. So this is a health and social issue that requires a national response. Low-impact initiatives, such as education and awareness raising, may not be enough.

The costs of alcohol to society are significant. A recent review estimated this to be £27 billion annually, with only half of this offset by tax revenue on alcohol products.

Timely access to specialist treatment can help to reduce the health risks associated with alcohol. Unfortunately, there have been significant cuts to funding for this type of intervention.

Around 80% of people classed as dependent on alcohol in England are not currently getting treatment support. While there has recently been extra funding for drug services to try and correct historic cuts, this has not been extended to alcohol. Reversing this by investing in services could help to reduce the rising number dying prematurely from alcohol.

A new strategy is long overdue

The last government strategy for alcohol was published in 2012, so there is a pressing need for a new one. This must address all the ways that the harms from alcohol can be tackled, from marketing and pricing to specialist treatment and recovery services.

A group, led by Liverpool MP Dan Carden, with cross-party support, recently called on the government to initiate an independent review of alcohol harm, along the lines of the review led by Dame Carol Black, which had a significant influence on drug policy and treatment funding.

Without such a review and strategy based on it, the harms caused by alcohol including premature death will continue to rise year after year. So much has changed since the last alcohol strategy in 2012 not least the current cost of living crisis. The outlook for investment in public health looks bleak, added to which this government doesn’t seem willing to curtail the efforts of the alcohol industry in marketing and protecting its products.
