A Columbia University study has found that adversity early in life is associated with increased gastrointestinal symptoms in children that may have an impact on the brain and behavior as they grow to maturity.

The study was published online March 28 in the journal Development and Psychopathology.

“One common reason children show up at doctors’ offices is intestinal complaints,” said Nim Tottenham, a professor of psychology at Columbia and senior author on the study. “Our findings indicate that gastrointestinal symptoms in young children could be a red flag for future emotional health problems.”

Scientists have long noted the strong connection between the gut and brain.

At work, it’s healthier and more productive just to be yourself, according to a new study from Rice University, Texas A&M University, the University of Memphis, Xavier University, Portland State University and the University of California, Berkeley.

The study, “Stigma Expression Outcomes and Boundary Conditions: A Meta-Analysis” will appear in an upcoming edition of the Journal of Business and Psychology. It examines 65 studies focusing on what happens after people in a workplace disclose a stigmatized identity, such as sexual orientation, mental illness, physical disability or pregnancy.

Eden King, a co-author of the study and an associate professor of psychology at Rice, said the decision to express a stigmatized identity is highly complicated.

“It has the potential for both positive and negative consequences,” she said.

However, the research overwhelmingly indicates that people with non-visible stigmas (such as sexual orientation or health problems) who live openly at work are happier with their overall lives and more productive in the workplace. King said self-disclosure is typically a positive experience because it allows people to improve connections, form relationships with others and free their minds of unwanted thoughts.

What’s an s-shaped animal with scales and no legs?  What has big ears, a trunk and tusks? What goes ‘woof’ and chases cats? The brain’s ability to reconstruct facts – ‘a snake’, ‘an elephant’ and ‘a dog’ – from clues has been observed using brain scanning by researchers at Aalto university. Their study was published today in Nature Communications.

In the research, test subjects were given three clues to help them guess what familiar objects the clues described. In addition to well-known animals, the clues depicted vegetables, fruits, tools and vehicles. The familiar objects and concepts described in the clues were never presented directly to the test subjects.

The researchers at Aalto University demonstrated that brain activation patterns contained more information about the features of the concept than had been presented as clues. The researchers concluded that the brain uses environmental clues in an agile way to activate a whole range of the target concept’s properties that have been learned during life.

An international team of researchers has identified, for the first time, the cell types, areas and biological processes in the brain that mediate the genetic risk of insomnia. This was made possible by assessing DNA and sleep features in no less than 1.3 million people. The findings are a major step towards getting a grip on the biological mechanisms that cause insomnia.

Insomnia is one of the most common disorders. Many people occasionally have a bad night of sleep. One out of ten people chronically experience poor sleep and suffer severely from the daytime consequences. Worldwide, 770 million people have chronic insomnia.

New research shows a quarter of girls (24%) and one in 10 boys (9%) are depressed at age 14.

​Researchers from the UCL Institute of Education and the University of Liverpool analysed information on more than 10,000 children born in 2000-01 who are taking part in the Millennium Cohort Study.

At ages 3, 5, 7, 11 and 14, parents reported on their children’s mental health. Then, when they reached 14, the children were themselves asked questions about their depressive symptoms.

Based on the 14-year-olds reporting of their emotional problems, 24 per cent of girls and 9 per cent of boys suffer from depression.

The research, published with the National Children’s Bureau, also investigated links between depressive symptoms and family income. Generally, 14-year-olds from better-off families were less likely to have high levels of depressive symptoms compared to their peers from poorer homes.

Many professions - paramedics, police, firefighters - involve helping people in traumatic circumstances but witnessing trauma has its own effects that can haunt people for life.

When we think about workplace safety, we often think about introducing or improving initiatives to ensure the physical safety of workers.

In recent years, there’s also been a growing awareness around ensuring not just the physical but also the psychological wellbeing of employees, with more organisations now working to manage the impact of vicarious trauma in the workplace.
​
While vicarious trauma will never be eliminated from trauma-exposed workplaces, it is possible for organisations to effectively manage it, which has been shown to reduce attrition rates and unplanned absences, and boost the workplace culture.

Talk therapy can help those with chronic gastrointestinal conditions
It’s widely recognised that emotions can directly affect stomach function. As early as 1915, influential physiologist Walter Cannon noted that stomach functions are changed in animals when frightened. The same is true for humans. Those who stress a lot often report diarrhoea or stomach pain.

We now know this is because the brain communicates with the gastrointestinal system. A whole ecosystem comprising 100 trillion bacteria living in our bowels is an active participant in this brain-gut chat.

Recent discoveries around this relationship have made us consider using talk therapy and antidepressants as possible treatments for symptoms of chronic gut problems. The aim is to interfere with the conversation between the two organs by telling the brain to repair the faulty bowel.
​
Our research found talk therapy can improve depression and the quality of life of patients with gastrointestinal conditions. Antidepressants may also have a beneficial effect on both the course of a bowel disease and accompanying anxiety and depression.

Unhelpful stereotypes that disguise the true extent of eating disorders are present in the Netflix series
To the Bone – a film about a turning point in a young woman’s battle with anorexia nervosa – has attracted comment from mental health professionals and advocates. Critics have concerns it could cause or worsen eating disorder symptoms.
​
The writer-director of To the Bone assured audiences she wished to dispel myths, not do harm. So which aspects of the new film might do harm, and which might educate the audience in a positive way?

How might the film cause harm?​
