New study throws light on impact of isolation on mental health

Washington [US], September 3 (ANI): The findings of a new Cornell University research suggested that female mice exhibit a strong drive to socialize with other females following periods of acute isolation, significantly increasing their production of social calls that are akin to human emotional vocalizations.The researchers, whose study was published in PLOS ONE, said their behaviour suggests a promising pathway for understanding the brain mechanisms through which isolation affects people's social motivation and mental health - a growing concern during the COVID-19 pandemic."That kind of social interaction between female mice is the most equivalent to our daily interactions with other people," said Katherine Tschida, assistant professor of psychology in the College of Arts and Sciences.

Recovery period from normal concussion can last up to one month

Michigan [US], September 3 (ANI): The findings of the largest study to be ever done on college athletes has redefined the timeline for recovery from concussion. Previously the normal recovery time was of up to 14 days, which has now been extended up to 28 days.The findings have been detailed in the journal 'Sports Medicine', in one of the marquee papers to emerge from the NCAA-DoD Concussion Assessment, Research and Education Consortium.The study's lead researcher, Steve Broglio, director of the University of Michigan Concussion Center, is on the CARE Consortium leadership team and leads the CARE clinical study core. "Normal return-to-play time was previously set at 14 days--meaning 50 per cent of people recovered in that time. Our paper suggests that 28 days more fully encapsulates the re...

Human health at risk from long-term exposure to air pollution below current air quality standards: Study

London [UK], September 2 (ANI): A new study has suggested that long-term exposure to air pollution appears to still be linked to higher mortality despite the existence of air quality standards that restrict levels of pollution.The findings of the study were published online in 'The BMJ'.Researchers found evidence of higher death rates amongst people who had been exposed to more air pollution even though the levels were allowed under current official standards.Previous studies have found an association between long term exposure to outdoor air pollution such as those in the form of fine particles in the air (known as particulate matter or PM2.5) and nitrogen dioxide (NO2) and poor health or death.Air pollution concentrations have fallen substantially in Europe since the 1990s, but it is unc...

Study shows having MS plus depression may be tied to increased risk of death

Washington [US], September 2 (ANI): A new study has shown that people with depression and multiple sclerosis (MS) may be more likely to die over the next decade than people with just one or neither condition.The findings of the study were published in the journal 'Neurology', the medical journal of the American Academy of Neurology.The study also found that people with MS and depression have an increased risk of developing a vascular disease such as heart attack and stroke."These findings underscore the importance of identifying depression in people with MS as well as monitoring for other risk factors for heart disease and stroke," said study author Raffaele Palladino, MD, PhD, of Imperial College of London in the United Kingdom."Future studies need to be conducted to look at whether treat...

Older people with abdominal fat, weak muscles more likely to develop mobility problems: Study

Sao Paulo [Brazil], September 1 (ANI): A new study has found that the dangerous combination of weak muscles and abdominal fat can lead to a significant loss of gait speed in older people.The findings of the study were published in the journal 'Age and Ageing'.The study was conducted by researchers at the Federal University of Sao Carlos (UFSCar) in the state of Sao Paulo, Brazil, in partnership with colleagues at University College London (UCL) in the UK.A slower gait is a natural outcome of the ageing process, but mobility problems can result if the walking speed falls sharply.Everyday activities such as crossing the street before the traffic lights change become increasingly difficult, and there may be a heightened risk of falling as well as a gradual loss of independence if the conditio...

Breast milk of mothers who received COVID-19 vaccine contains antibodies that fight illness: Study

Washington [US], August 29 (ANI): The breast milk of lactating mothers vaccinated against COVID-19 contains a significant supply of antibodies that may help protect nursing infants from the illness, according to new research from the University of Florida.The study was published in the journal Breastfeeding Medicine and was funded by the Children's Miracle Network."Our findings show that vaccination results in a significant increase in antibodies against SARS-CoV-2 -- the virus that causes COVID-19 -- in breast milk, suggesting that vaccinated mothers can pass on this immunity to their babies, something we are working to confirm in our ongoing research," said Joseph Larkin III, PhD, senior author of the study and an associate professor in the UF/IFAS department of microbiology and cell sci...

Young athletes with history of concussions may have more changes to their brains: Study

Washington [US], August 29 (ANI): A recent study suggests athletes with a history of concussion may show more brain injury from a later concussion, particularly in middle regions of the brain that are more susceptible to damage, when compared to athletes with no history of concussion.The research was recently published in the online issue of Neurology, the medical journal of the American Academy of Neurology.The athletes participated in sports like football, volleyball and soccer."We know concussions may have long-term effects on the brain that last beyond getting a doctor's clearance to return to play," said study author Tom A. Schweizer, PhD, of St. Michael's Hospital in Toronto, Canada.He added, "It is unclear, however, to what extent the effects of a repeated concussion can be detected...

Researchers explain spleen-heart connection in cardiac repair

Washington [US], August 29 (ANI): Using a mouse model of heart failure, a team of researchers recently discovered new mechanisms to help define how the spleen and heart coordinate physiological inflammation in cardiac repair.Through the study published in the American Journal of Physiology-Heart and Circulation, the researchers at the University of South Florida (USF Health) has analyzed the interactions of the lipid mediator sphingosine-1-phosphate (S1P) in the spleen and heart during the transition from acute to chronic heart failure.Although we can survive without a spleen, evidence continues to mount that this abdominal organ plays a more valuable role in our physiological defenses than previously suspected."The spleen holds a whole army of immune cells and signaling molecules that can...

Study finds screening for atrial fibrillation could reduce risk of stroke

Stockholm [Sweden], August 30 (ANI): Screening for atrial fibrillation in 75- and 76-year-olds could reduce the risk of stroke, severe bleeding, and death, according to a study at Karolinska Institutet in Sweden.The study was published in the journal The Lancet.Atrial fibrillation, a form of arrhythmia or irregular heartbeat, is associated with a five-fold increased risk of stroke. The symptoms are often deleterious since large blood clots can form in the heart, break free and risk clogging large vessels in the brain and cause stroke. Anticoagulant therapy reduces the risk of stroke. Still, countries do not screen the general population for atrial fibrillation, but rather treat those patients who are discovered during routine care."There has never really been a study that examines if it wo...

Study shows downside of not receiving second shot of COVID-19 vaccine

Washington [US], August 31 (ANI): A new study has shown that two months after the second Pfizer/Moderna vaccination, antibody response decreases 20 per cent in adults with prior cases of COVID-19. The study also tested how well current vaccines resist emerging variants.The findings of the study were published in the journal 'Scientific Reports'.The Northwestern University study underscored the importance of receiving a second dose of vaccine, not only because it is commonly known that immunity from vaccines wanes over time, but also because of the risk posed by emerging variants, including the highly contagious delta variant.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 va...
