Bangalore / New Delhi, Jul 20 (EFE/EPA).- The official Covid-19 death toll in India stood at around 400,000 at the end of June 2021 but the reality could be “catastrophically worse,” with estimates of excess deaths in the Asian country during the pandemic being as high as 4 million according to a new research published Tuesday.Excess mortality is an estimation of the number of deaths from all causes during a crisis that are above normal levels.Earlier this year, India was overwhelmed by a huge second wave of Covid-19, which pushed the country’s hospitals to the brink amid a shortage of oxygen and medical supplies.

Gizmodo reports certain bacteria spread by cat scratches and other animal exposures can sometimes have a dramatic impact on the brain. A new study profiles a group of patients with psychiatric illness who simultaneously showed signs of infection from bacteria called Bartonella. Bartonella bacteria aren’t usually linked to serious illness in people. But certain groups, like those immunocompromised, might be more vulnerable generally. The rod-shaped Bartonella bacteria can survive and replicate inside other cells, much like viruses. This ability allows them to evade conventional tests for detecting infection and makes it harder for antibiotics to kill them. Bartonella henselae is the most commonly seen infection in humans and causes cat scratch disease--also called cat scratch fever. Despite the name, B. henselae and other disease-causing Bartonella can be spread through dogs and other mammals, and parasites like ticks, fleas, and lice. I
Scientists have identified the brain's 'signature' for major depression. According to UPI, Japanese researchers used machine learning to ID distinct patterns of coordinated brain activity in people with major depressive disorder. Major depression is fairly easy to diagnose. However, the researchers say a better understanding of the brain networks associated with the disease could improve treatment. The new brain network signature could serve as a foundation for discovering brain network patterns associated with different types of depression. It could also reveal relationships between depression and other disorders.
A new study has identified a link between stress hormones and the recurrence of cancer. UPI reports the findings may explain why cancers can return long after seemingly being cured with chemotherapy or surgery. The study showed stress hormones and immune cells called neutrophils may awaken dormant cancer cells and cause tumors to regrow -- even after treatment -- according to a study published Wednesday by Science Translational Medicine. Tumor recurrence may be facilitated by common stress. Study co-author Dr. Dmitry Gabrilovich Chief Scientist, AstraZeneca Stress hormones such as cortisol have been linked with an increased risk for a number of health problems. Elevated levels of these hormones can increase a person's heart rate and lead to rises in blood pressure. Because of this, it can lead to insomnia, robbing the body of needed sleep, and mental health disorders such as anxiety and depression.
