Early warning signals could help monitor disease outbreaks

New research suggests early warning signals (EWSs) could help in the monitoring of disease outbreaks, such as COVID-19. The study found warnings could be detected weeks earlier than any rapid increase in cases. The findings could help governments and policy makers improve the accuracy of their decisions and allow timely interventions if needed. from Top Health News -- ScienceDaily https://ift.tt/3DvxDk4 via IFTTT

COVID-19 antibody study shows downside of not receiving second shot

A new study shows that two months after the second Pfizer/Moderna vaccination, antibody response decreases 20 percent in adults with prior cases of COVID-19, and tests how well current vaccines resist emerging variants. The study also showed that prior exposure to SARS-CoV-2 does not guarantee a high level of antibodies, nor does it guarantee a robust antibody response to the first vaccine dose. This directly contradicts the assumption that contracting COVID will naturally make someone immune to re-infection. The findings further support vaccination (and two doses), even for people who have contracted the virus previously.

Pathomechanisms in heart disease discovered

The largest protein in the human body, titin, enables elastic movements of our muscles, including the heart. Mutations in the titin gene (TTN) that impair this function and lead to heart muscle disease. The pathomechanisms behind this -- i.e. why TTN mutations trigger disease -- were unclear until now. A team of experts has now investigated these pathomechanisms in more detail and has gained ground-breaking insights. from Top Health News -- ScienceDaily https://ift.tt/3EOEi9S via IFTTT

Color-changing bandages sense and treat bacterial infections

Antibiotic resistance is one of the biggest threats to global health. Sensing and treating bacterial infections earlier could help improve patients' recovery, as well curb the spread of antibiotic-resistant microbes. Now, researchers have developed color-changing bandages that can sense drug-resistant and drug-sensitive bacteria in wounds and treat them accordingly. from Top Health News -- ScienceDaily https://ift.tt/37Gz2VU via IFTTT
