The School of Chinese Medicine at Hong Kong Baptist University (HKBU) found that 55% of the patients who sought medical treatment from the “HKBU Chinese Medicine Telemedicine Centre Against COVID-19” during the fifth wave of the COVID-19 pandemic continued to experience at least one long COVID symptom for six months to a year after diagnosed with an infection. The most common symptoms are fatigue, brain fog and cough.

A researcher from Osaka University has investigated the associations between mask usage and the reasons people give for wearing a mask. Online surveys were conducted before and after policies that downgraded the status of COVID-19. The study found that 59% of respondents continued wearing masks even after policy changes. Several sociological and psychological reasons other than disease prevention for mask usage were identified.

A broad-spectrum antiviral drug candidate, 2-thiouridine, that targets positive-strand RNA viruses has been identified and characterized.

The shortlist for the Applied Microbiology International Awards 2023 has now been announced. The AMI Awards programme is designed to celebrate the brightest minds in our field and promote the research, group, projects, products and individuals who continue to help shape the future of applied microbiology.

The researchers from Osaka University showed how two psychological factors, belief in just deserts (BJD) and human rights restrictions (HRR), differ across countries. BJD tended to be higher in Japan and lower in the UK, whereas HRR was higher in China and lower in Japan. Public health messages for high-HRR individuals could potentially be used effectively to reduce disease-related discrimination and prejudice.

Applied Microbiology International (AMI) is boosting training and development opportunities for early career scientists in journal publishing with the appointment of 14 new junior editors on its flagship journal Letters in Applied Microbiology (LAM). They were selected from more than 100 applicants by the Editor-in-Chief, Dr Marcela Hernández.

How much is adequate screen time for a child? It is the question at the forefront of many parents’ minds. Now, a recent cohort study has found that the amount of screen time spent by one-year-olds is associated with developmental delays.

Study suggests broad-spectrum vaccines with wide coverage necessary to achieve effective immunity against future, functionally-distinct variants.

Scientists have isolated potent neutralising antibodies from a COVID-19 vaccinated SARS survivor that exhibited remarkable breadth against known sarbecoviruses. The antibodies targeted a conserved region of the spike protein and blocked receptor binding and viral fusion. These findings could guide the development of broadly active therapeutics against current and future coronaviruses.

What scientists learned about the rare antibodies targeting SARS-CoV-2’s Achilles’ heel could help fine-tune our COVID-19 vaccine strategy for longer-lasting immunity.

Singapore scientists find use of healthcare resources, absenteeism and reduced productivity due to mental health issues place a significant burden on Singapore’s economy.

With many countries enacting strict lockdowns in the wake of the COVID-19 pandemic, economists have begun looking at the wider implications of such policies. Typically, they employ a cost-benefit analysis, but this has certain limitations. To overcome these limitations, a Tohoku University professor has turned to a surprising source: physics

The COVID-19 pandemic has made us more aware of the aerosols that hang around in the air and spread certain infectious diseases. Common dental procedures can be potentially hazardous in this regard. Therefore, it is crucial for researchers to be able to measure how aerosols spread so they can reduce them. A recent study harnessed a high-sensitivity camera and a high intensity LED light source, along with a mannequin and dental air turbine, to measure the spread of aerosols and the effectiveness of various means to reduce them.

Researchers from Osaka University have found that repeated high-dose treatment, known as pulse therapy, with the steroid methylprednisolone reduces in-hospital deaths in COVID-19 patients who receive invasive mechanical ventilation, but not in patients who don’t receive invasive mechanical ventilation. These findings were only possible using appropriate statistical methods to remove bias from the data, which originally seemed to show that the opposite was true. These results can improve patient treatment and reduce COVID-19-related deaths worldwide.

A research group from Osaka Metropolitan University investigated the relationship between tobacco use, including heated tobacco products, with the risk of SARS-CoV-2 infection and severe COVID-19. The researchers administered an online survey of living conditions in February 2022 to 30,130 participants aged 16-81 years, finding that heated tobacco product users had significantly higher rates of SARS-CoV-2 infection compared to non-tobacco users. Furthermore, the research group found that among all tobacco users, those who used both heated tobacco products and traditional cigarettes had the highest incidence of requiring hospitalization or oxygen due to COVID-19.

PAXLOVID™ rollout continues with Laos, Malawi, Rwanda and Zambia as international access to oral treatments improves.

An Osaka University study investigated how the COVID-19 onset and media coverage affected hand hygiene compliance. Voluntary use of hand sanitizer in a hospital rose from 5% in December 2019 to 70%+ by August 2020. In the same period, TV coverage reached 7.7 hours/day on a national broadcaster. The study’s simulations found a significant relation between TV coverage and hand hygiene compliance, though no correlation between compliance and newly confirmed COVID-19 cases and deaths.

Researchers in Sarawak, Malaysia, measured the immunity responses of people who received different COVID-19 vaccines.

A research group from the Osaka Metropolitan University Graduate School of Medicine conducted a survey of 285 patients regarding the long-term aftereffects of COVID-19. As a result, they revealed that more than half of COVID-19 patients still had residual symptoms, even close to a year afterward. It became clear that fatigue, abnormalities in senses of taste and smell, hair loss, and sleep disorders could persist, regardless of the severity of the initial COVID-19.

Sifting through sewage for SARS-CoV-2 genetic material could help authorities tailor infection control policies.

Team studies discrimination, mental distress, and work impairment in COVID-19 survivors.

Researchers from Osaka University have shown sex-specific differences in the immune response to COVID-19 infection. By identifying and analyzing the immune cell population in COVID-19 patients, they showed that infection results in a reduced ratio of circulating follicular T regulatory (cTfr) cells to a network of antibody-producing proteins, correlated with dysregulated antibody production. This cTfr cell reduction is more significant in males, providing cellular evidence for the observed association between increased risk and male sex.

Researchers from Osaka University compared the sensitivity of rapid antigen tests (RATs) and polymerase chain reaction (PCR) tests for the Omicron variant of COVID-19 using data produced by the Japan Professional Football League. They found the comparative sensitivity of RATs for Omicron was not affected by the duration from the onset of symptoms to testing.

Researchers led by Osaka University demonstrated the role of endothelial cell-specific protein Roundabout4 (Robo4) in the reduction of vascular permeability and mortality in mouse models of severe infection. The research team identified a drug inhibitor that increased Robo4 expression and reduced mortality in sepsis and SARS-CoV-2 mouse models of infection. These findings may aid in the development of drugs to reduce the mortality rate of severe infectious diseases.
