New data fusion method classifies skin lesions more precisely than prior algorithms

Dermatologists typically classify skin lesions based on multiple data sources. Algorithms that fuse the information together can support this classification. An international research team has now developed an algorithm that classifies skin lesions more accurately than previous algorithms by using an improved data fusion process.

New model to identify biological markers in patients with COVID-19 and other illnesses

Investigators who recently developed a mathematical model that indicated why treatment responses vary widely among individuals with COVID-19 have now used the model to identify biological markers related to these different responses.

Study analyzes the impact of global trust in government due to the COVID-19 pandemic

In a week when the UK Prime Minister Boris Johnson has admitted to breaking Covid-19 lockdown rules, a new study has found that impartial, transparent and truthful government communications are fundamental for achieving and maintaining government trust during public health emergencies.

COPD: Ion channels in immune cells could potentially be targets for new therapies

Chronic obstructive pulmonary disease – COPD for short – is one of the most common diseases of the lung. It affects almost 300 million people worldwide, of which about three million die every year.

Protein biomarkers in urine could be used to diagnose concussion and monitor recovery

Concussion can be frustratingly hard to diagnose and track. The injury doesn't show up on routine brain scans, and there is no definitive diagnostic test. It's usually diagnosed based on symptoms, and, in athletes, comparison with baseline testing if it was done. But concussion symptoms are non-specific, unreliable, and easily influenced by emotions.

Free-energy principle can explain how neural networks are optimized for efficiency

The RIKEN Center for Brain Science (CBS) in Japan, along with colleagues, has shown that the free-energy principle can explain how neural networks are optimized for efficiency.

Discovery opens up the possibility of pursuing new therapies for FOP

Fibrodysplasia ossificans progressiva (FOP) is a rare disease characterized by extensive bone growth outside of the normal skeleton that pre-empts the body's normal responses to even minor injuries. It results in what some term a "second skeleton," which locks up joint movement and could make it hard to breathe.

Pregnant women who contracted COVID-19 more likely to have poor birth outcomes

People who contracted COVID-19 while pregnant were more likely to have poor birth outcomes including preterm birth, small for gestational age, low birth weight, and stillbirth.

New pioneering test helps predict the spread of deadly skin cancer

A pioneering test which reliably predicts the spread or return of the most deadly form of skin cancer has been developed by a team of Newcastle scientists and clinicians.

Study analyzes the link between consuming sweeteners during pregnancy and a child's risk of obesity

A new study investigates the link between consuming sweeteners during pregnancy and a child's risk of obesity. Pregnant rats fed with stevia or aspartame gave birth to pups that had a higher risk of obesity and specific changes in their gut microbiome. The findings highlight the importance of maternal nutrition during pregnancy.

Mutations in SARS-CoV-2 Omicron variant promote cell binding

Researchers in Germany, based on their recent study published in the journal ChemBioChem, have proposed that the elevated occurrence of positively charged amino acids in specific domains of the severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) Omicron variant spike protein improves viral binding to cellular negatively charged receptors aiding in enhanced infectiousness.

Monitoring rodents for SARS-CoV-2 and other coronaviruses, Hong Kong

A new study published in the Centers for Disease Control and Prevention’s Emerging Infectious Diseases journal has hypothesized that locations with positive SARS-CoV-2 in sewage could be used as potential surveillance targets to analyze if pestiferous urban rodents shed SARS-CoV-2 into the environment.

Topical antiseptic Acriflavine inhibits SARS-CoV-2 and other betacoronaviruses

A new study, published in the journal Cell Chemical Biology, has reported the discovery of acriflavine (ACF), an effective inhibitor of SARS-CoV-2. This drug is a mixture of trypaflavines (3,6-diamino-10-methylacridinium chloride and 3,6-diamino-3-methylacridinium chloride) and proflavine (3,6-diaminoacridine).

Study reveals long-term mental impacts of repeated exposure to major disasters

Repeated exposure to major disasters does not make people mentally stronger, a recent study from the Texas A&M University School of Public Health found: individuals who have been repeatedly exposed to major disasters show a reduction in mental health scores.

Cannabidiol may improve innate immune response against SARS-CoV-2

A recent study shows evidence that cannabidiol, an important active ingredient in the Cannabis sativa plant, can augment the antiviral innate immune response and prophylactically prime the innate antiviral response of cells – enabling in turn improved response against viruses such as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

CDC updates consumer webpage describing masks, respirators used to prevent COVID-19

CDC has updated our consumer webpage describing the types of masks and respirators used to prevent the transmission of SARS-CoV-2. Masking is a critical public health tool to prevent the spread of COVID-19, and it is important to remember that any mask is better than no mask.

WHO's recommendation provides two new options for treating COVID-19

WHO has recommended two new drugs for COVID-19, providing yet more options for treating the disease. The extent to which these medicines will save lives depends on how widely available and affordable they will be.

Rapid antigen test for SARS-CoV-2 proves to be highly accurate for pediatric populations

In a large prospective study of just over 1,000 patients ages 17 and younger who were seen at the Baltimore Convention Center Field Hospital (BCCFH) testing site during a seven-month period last year, researchers from Johns Hopkins Medicine and collaborating institutions report that a rapid antigen test for SARS-CoV-2 — the virus that causes COVID-19 — proved highly accurate when compared to the established standard virus detection method: the polymerase chain reaction (PCR).
