Who is most at risk after a heart attack?
A study investigates which people are most at risk of premature death due to cardiovascular disease after having a heart attack. One biomarker may help healthcare providers to personalize their predictions.
Acute coronary syndrome (ACS) describes a range of cardiovascular conditions that are characterized by a sudden and dangerous reduction of blood flow to the heart.
ACS can also, in some cases, lead to a major heart attack.
So far, the known risk factors for ACS include age (it is most common in people over 65), gender (with men being more at risk than women), and medical history (with diabetes, hypertension, and high cholesterol being the main culprits).
Recently, researchers from the University of Sheffield in the United Kingdom set out to investigate whether or not there are any biomarkers that could predict an elevated risk of ACS in people who have already been through a heart attack.
Lead researcher Prof. Robert Storey — from the university's Department of Infection, Immunity and Cardiovascular Disease — and his team noticed that blood plasma might provide practitioners with the clue they need to detect the possibility of cardiovascular disease.
Their findings were published in the European Heart Journal
Early nutritional intake related to brain growth in preterm neonates
Preterm neonates who received higher nutritional intake and enteral feeding primarily with breast milk during the first 2 weeks of life were more likely to have greater brain growth, according to recently published study results in Pediatrics.
“To our knowledge, this is the first preterm cohort study in which brain growth as measured on 3 serial scans in relation to early nutrition is examined,” Juliane Schneider, MD, of the pediatrics department, University of Toronto and the Hospital for Sick Children, Toronto, and colleagues wrote. “Higher energy intake during the first 2 weeks of life predicted enhanced brain development, with a positive effect on both [gray matter] and [white matter (WM)], as indicated by more robust growth of the subcortical structures, the cerebellum and the total brain and accelerated WM microstructural maturation to term age, with remarkable consistency across brain measures.” MORE ON Healio
Menopause and Rheumatoid Arthritis
Menopause may speed physical decline in women with rheumatoid arthritis (RA), a new study suggests.
While rheumatoid arthritis rates in women are three times higher than in men, and women with RA have more severe physical decline and disability, sex-based differences in RA are poorly understood, the researchers said.
Rheumatoid arthritis is an autoimmune disorder that causes inflammation and painin the joints.
Other research has shown that rheumatoid arthritis in women is influenced by childbirthand other reproductive and hormonal changes. For example, the study authors pointed out that women with early menopause are more likely to develop RA than those with normal or late menopause.
"Further study is needed as to why women with rheumatoid arthritis are suffering a greater decline in function after menopause," said study lead author Elizabeth Mollard. She's an assistant professor of nursing at the University of Nebraska College of Nursing in Lincoln.
To learn more, Mollard and her colleagues looked at nearly 8,200 women with rheumatoid arthritis. Those women whose periods had not yet stopped had slower physical decline than those who were postmenopausal, the study found.
While only an association was seen, the results suggest menopause has a significant impact on the degree and rate of physical decline in women with rheumatoid arthritis and is linked to worsening disease.
The study was published Jan. 29 in the journal Rheumatology.
