Genes behind coronary artery disease identified for 1st time

A team of US researchers and their collaborators have identified genes that play key roles in the development of coronary artery disease, the top cause of death worldwide. New York, Feb 3 : A team of US researchers and their collaborators have identified genes that play key roles in the development of coronary artery disease, the top cause of death worldwide. The University of Virginia (UVA) researchers' findings essentially pick culprits responsible for coronary artery disease (CAD) out of a far, far larger lineup of potential genetic suspects, giving scientists promising targets as they work to develop new and better treatments. "Genetic studies done in more than 1 million people in the last 15 years identified hundreds of locations on our chromosomes that increase the ri...

Gum infection may lead to serious heart problem: Study

A gum disease called periodontitis can lead to a litany of dental issues from bad breath to bleeding and lost teeth, and now it is found that it could also lead to a serious heart problem, a new study has shown. Tokyo, Jan 28 : A gum disease called periodontitis can lead to a litany of dental issues from bad breath to bleeding and lost teeth, and now it is found that it could also lead to a serious heart problem, a new study has shown. According to the study published in Clinical Electrophysiology, the team of researchers found a significant correlation between periodontitis and fibrosis -- scarring to an appendage of the heart's left atrium that can lead to an irregular heartbeat called atrial fibrillation -- in a sample of 76 patients with cardiac disease. "Periodontitis ...

Screening newborn babies for congenital hyperthyroidism is critical: Doctors

Doctors say that screening newborn babies for congenital hyperthyroidism (CH) is critical. Dr Yogesh Kumar Gupta, consultant-pediatrics, Fortis Hospital here, said that it is very important to screen newborn babies for CH as failure to do so can lead to mental retardation in babies. The medical fraternity considers January as Thyroid Awareness Month. Bengaluru, Jan 30 : Doctors say that screening newborn babies for congenital hyperthyroidism (CH) is critical.

Covid immunity strengthens over time in vaccinated people: Study

The human body's immunity to Covid-19 appears to gather strength with more time between vaccination and infection, a new study has shown. San Francisco, Jan 27 : The human body's immunity to Covid-19 appears to gather strength with more time between vaccination and infection, a new study has shown. According to US-based Oregon Health & Science University (OHSU) study, it suggests people, who have had Covid-19, have benefited from vaccination, even if they delayed it. In this study, researchers measured the immune response in blood samples for people, who gained hybrid immunity by either getting vaccinated before a breakthrough infection or by getting vaccinated after contracting Covid-19. The researchers measured the immune response in 96 generally healthy employees ...

Are Covid vaccines affecting the heart, inducing other non-communicable diseases?

While the Covid-19 vaccines are saving lives, serious side effects, inducing inflammation in the heart, have been reported after vaccinations, along with other premature non-communicable diseases (NCDs). New Delhi, Jan 25 : While the Covid-19 vaccines are saving lives, serious side effects, inducing inflammation in the heart, have been reported after vaccinations, along with other premature non-communicable diseases (NCDs). However, new research now claims the reported adverse events are low in number. According to the WHO, more than 850 million cases and over 6.6 million deaths from Covid have been reported worldwide. Currently, the death rate has been reduced due to the decreased pathogenicity of new SARS-CoV-2 variants, but the major factor in the reduced death rates ...

Hybrid immunity best protection against Covid-19: Researchers

People with hybrid immunity are the most protected against severe illness and reinfection, a new study has found. Toronto, Jan 22 : People with hybrid immunity are the most protected against severe illness and reinfection, a new study has found. Results from global data show vaccination and a prior Covid-19 infection offer the best defence against severe illness and reinfection, according to a University of Calgary research group. Hybrid immunity occurs when someone has had at least the full series of vaccines and has a prior infection, in any order. The study published in The Lancet Infectious Diseases will help public policy makers understand the optimal timing of vaccinations. "The results reinforce the global imperative for vaccination. A common question throughou...

Female, male hearts respond differently to stress hormone

Female and male hearts respond differently to the stress hormone called noradrenaline, a study in mice has revealed. New York, Jan 22 : Female and male hearts respond differently to the stress hormone called noradrenaline, a study in mice has revealed. The findings may have implications for human heart disorders like arrhythmias and heart failure and how different sexes respond to medications, according to the study published in Science Advances. The team built a new type of fluorescence imaging system that allowed them to use light to see how a mouse heart responds to hormones and neurotransmitters in real time. The mice were exposed to noradrenaline, also known as norepinephrine. Noradrenaline is both a neurotransmitter and hormone associated with the body's "fight ...

Older adults with asthma at high risk of depression during Covid: Study

Older adults with asthma were at high risk of depression during the Covid-19 pandemic, a new study has shown. New Delhi, Jan 20 : Older adults with asthma were at high risk of depression during the Covid-19 pandemic, a new study has shown. According to the study published in the journal Respiratory Medicine, the numbers were extremely concerning for older adults with asthma who had previously experienced depression, with approximately one-half experiencing a recurrence of depression during the autumn of 2020, which was significantly higher than recurrence rates among their peers who did not have asthma. However, those who were lonely had substantially elevated rates of depression. "When considering the high comorbidity between asthma and depression prior to the pandemic,...
