Research links personality traits with hallmarks of Alzheimer’s disease

Washington [US], October 13 (ANI): New research from the Florida State University College of Medicine found that changes in the brain associated with Alzheimer's disease are often visible early on in individuals with personality traits associated with the condition.The study published in the journal Biological Psychiatry focused on two traits previously linked to the risk of dementia: neuroticism, which measures a predisposition for negative emotions, and conscientiousness, which measures the tendency to be careful, organized, goal-directed, and responsible."We have done studies showing who's at risk of developing dementia, but those other studies were looking at the clinical diagnosis," said Antonio Terracciano, professor of geriatrics at the College of Medicine. "Here, we are looking at ...

Study finds clean air matters for a healthy brain

Washington [US], October 8 (ANI): Research on air pollution and cognitive decline has indicated that cleaner air may reduce the risk for Alzheimer's and other dementias.The findings of the study were published in 'The Journal of the Alzheimer's Association'.Two USC researchers whose work linked air pollution to a greater risk of Alzheimer's disease and faster cognitive decline are seeing signs that cleaner air can make a difference in brain health.Cars and factories produce a fine particulate known as PM2.5 that USC-led studies have linked to memory loss and Alzheimer's disease. Smaller than the width of human hair, these tiny particles pose a big problem. Once inhaled, they pass directly from the nose up and into the brain, beyond the blood-brain barrier that normally protects the brain f...

Psychiatric disorders in teenage years linked to social exclusion later: Study

Helsinki [Finland], October 11 (ANI): A birth cohort study of people born in Finland in 1987 has found that adolescents who had received a mental health disorder diagnosis were often excluded from the labour market and education as young adults. This particularly applied to adolescents who had been diagnosed with an autism spectrum disorder or psychosis.The findings of the study were published in 'The British Journal of Psychiatry'.Almost 11 per cent of adolescents who had received a psychiatric diagnosis were excluded from education and the labour market for at least five years in their early adulthood. For other adolescents, this number was slightly under three per cent. The results have highlighted the importance of the treatment and rehabilitation of people with mental health disorders...

Research points to strategy for overcoming colorectal cancers’ immunotherapy resistance

Washington [US], October 12 (ANI): Immune checkpoint inhibitors, which unleash the immune response against tumor cells, have revolutionized cancer treatment; however, the medications aren't effective in a large number of patients, including those with colorectal cancer.New research published in the journal PNAS that was led by investigators at Massachusetts General Hospital (MGH) and the University of Geneva (UNIGE) provides insights into why some types of colorectal cancer don't respond to immune checkpoint inhibitors and offer a strategy to overcome their resistance."Colorectal cancer is the second leading cause of cancer-related death in the United States and worldwide," said senior and co-corresponding author Rakesh K. Jain, PhD, director of the E.L. Steele Laboratories for Tumor Biolo...

Study explores adverse complications for COVID positive pregnant women, their newborns

London [UK], October 12 (ANI): A new study, which finds an increased risk of poorer outcomes for the newborns and symptomatic women with COVID-19, adds further weight to the argument for pregnant women to be vaccinated for the virus.The peer-reviewed findings were published in The Journal of Maternal-Fetal and Neonatal Medicine.Assessing 2,471 women in the third trimester of their pregnancy, close to their delivery, researchers found "significant differences" for symptomatic covid positive patients including higher rates of gestational diabetes, lower white blood cell counts, and heavier bleeding during delivery, whilst respiratory complications were witnessed in their babies.Thankfully in the group of patients -- which included 172 covid positive women (56 of whom were symptomatic)-- moni...

COVID-19: Study finds out two metres distancing not enough without masks

Montreal [Canada], October 7 (ANI): According to researchers from Quebec, Illinois, and Texas, to prevent the spread of COVID-19 indoors, the two metres physical distancing guideline is not enough without masks.The findings of the study were published in the journal 'Building and Environment'.Wearing a mask indoors can reduce the contamination range of airborne particles by about 67 per cent."Mask mandates and good ventilation are critically important to curb the spread of more contagious strains of COVID-19, especially during the flu season and winter months as more people socialise indoors," said Saad Akhtar, a former doctoral student under the supervision of Professor Agus Sasmito at McGill University.While most public health guidelines recommend physical distancing of two metres for pe...

Study analyses pros, cons of common weight-loss surgeries

Washington [US], October 7 (ANI): A research team, led by the University of Michigan Health, has found that of the most common weight-loss surgeries, sleeve gastrectomy is safer than gastric bypass.The findings of the study were published in the journal 'JAMA Surgery'.Five years after each procedure, patients who'd undergone a sleeve gastrectomy, which involves removing part of the stomach, had a lower risk of death and complications than those who had chosen to have their stomachs divided into pouches through gastric bypass surgery.However, gastric bypass was superior in one area: Sleeve gastrectomy patients were more likely to need follow-up surgery, which could indicate that gastric bypass is more effective long-term, even though it carries more risks."It's really important for patients...

Study finds anti-nausea drug may help cancer patients survive longer

Washington [US], October 10 (ANI): According to a new study, patients with breast, pancreatic and certain other types of cancer may survive longer if given an anti-nausea drug during surgery.The findings of the study were presented at the ANESTHESIOLOGY 2021 annual meeting.Three months after their cancer surgery, more than three times as many patients who did not receive dexamethasone died, compared to those who received the drug, researchers found.Dexamethasone is given to patients to prevent nausea and vomiting after surgery and during chemotherapy. Researchers found dexamethasone can improve mid-to-long-term outcomes in patients with non-immunogenic cancers (those that don't provoke a strong immune response) such as sarcoma and cancers of the breast, uterus, ovary, oesophagus, pancreas,...

Study for better understanding of cystic fibrosis

Ottawa [Canada], October 10 (ANI): A new understanding of cellular defects related to Cystic Fibrosis (CF) could help pave the way for the treatment of the disease, according to researchers at the University of Saskatchewan (USask).Their findings of the study were published in the journal 'Cell Reports'.A team in the College of Medicine led by Drs Juan Ianowski (PhD) and Julian Tam (MD) found that sodium transport is abnormal in lungs with CF. The researchers, affiliated with the Respiratory Research Centre, studied the swine model of CF and used a specialised microelectrode technique that allowed them to perform experiments with very high resolution. They discovered there is excessive sodium absorption in the small airways, a previously unstudied site in the body."A precise understanding ...

Study finds years of exposure to air pollution, road traffic noise might increase heart failure risk

Washington [US], October 10 (ANI): The findings of a new study suggests that exposure to air pollution and road traffic noise over the course of many years may be associated with an increased risk of developing heart failure.The correlation appears to be even greater in people who are former smokers or have high blood pressure. These findings of the research were published in the 'Journal of the American Heart Association', an open-access journal of the American Heart Association."We found that long-term exposure to specific air pollutants and road traffic noise increased the risk of incident heart failure, especially for former smokers or people with hypertension, so preventive and educational measures are necessary," said Youn-Hee Lim, PhD, lead author of the study and assistant professo...
