People with healthier heart structure and function appear to have better cognitive abilities, including increased capacity to solve logic problems and faster reaction times, according to research led by Queen Mary University of London and the Radcliffe Department of Medicine at University of Oxford.
Dr Zahra Raisi-Estabragh, BHF Clinical Research Training Fellow at Queen Mary University of London said: Heart disease and dementia are important and growing public health problems, particularly in ageing populations. We already knew that patients with heart disease were more likely to have dementia, and vice versa, but we ve now shown that these links between heart and brain health are also present in healthy people. We demonstrated for the first time, in a very large group of healthy people, that individuals with healthier heart structure and function have better cognitive performance.

A new strategy for capturing the 3D shape of the human face draws on data from sibling pairs and leads to identification of novel links between facial shape traits and specific locations within the human genome. Hanne Hoskens of the Department of Human Genetics at Katholieke Universiteit in Leuven, Belgium, and colleagues present these findings in the open-access journal
PLOS Genetics.
The ability to capture the 3D shape of the human face and how it varies between individuals with different genetics can inform a variety of applications, including understanding human evolution, planning for surgery, and forensic sciences. However, existing tools for linking genetics to physical traits require input of simple measurements, such as distance between the eyes, that do not adequately capture the complexities of facial shape.
A multidecade study of young adults living in the United Kingdom has found higher rates of mental illness symptoms among those exposed to higher levels of traffic-related air pollutants, particularly nitrogen oxides, during childhood and adolescence.
Previous studies have identified a link between air pollution and the risk of specific mental disorders, including depression and anxiety, but this study looked at changes in mental health that span all forms of disorder and psychological distress associated with exposure to traffic-related air pollutants.
The findings reveal that the greater an individual’s exposure to nitrogen oxides across childhood and adolescence, the more likely they are to show any signs of mental illness at the transition to adulthood, at age 18, when most symptoms of mental illness have emerged or begin to emerge.
South Asians in England at greater risk in second COVID wave, finds new study

LONDON: Minority ethnic groups in general and South Asians, in particular, had a higher risk of testing positive for SARS-CoV-2 and of COVID-19 related hospitalisations, intensive care (ICU) admissions and deaths during the second wave of the pandemic in the UK compared to the first, according to a new observational study of 17 million people.

Synopsis
Led by the London School of Hygiene & Tropical Medicine (LSHTM), the study published in the medical journal Lancet on Friday accounted for a large number of explanatory variables such as household size, social factors and health conditions across all ethnic groups and at different stages of COVID-19, from testing to mortality.
