E-mental health services could provide a response to these challenges and offer effective ways for prevention, diagnosis, treatment, and aftercare.

A large-scale qualitative study looks into the difficulties frontline doctors faced across two waves of the Covid-19 pandemic in the UK and Ireland since early 2020.

French researchers have found that addressing concerns related to the Covid-19 vaccination via a chatbot interface might be capable of swaying the vaccine-hesitant. Vaccine hesitancy is one of the major challenges in containing the Covid-19 pandemic. Previous studies have revealed that mass communication—through short messages relayed by television or radio—is not a very effective means of…

Colourful, 3D rendered scientific images are fascinating - but can they deceive viewers? New research from Spain suggests this might be the case. According to the study by the Instituto de Radio Televisión Española and the Universitat Autònoma de Barcelona conducted during the Covid-19 lockdown, black and white images of SARS-CoV-2 make the virus seem more infectious. The results, published on…

Claustrophobia or anxiety can overwhelm small children and people with cognitive difficulties, especially in a confining and noisy MRI scanner tube. Their restless reactions can then render scan images useless. To help such patients to relax during scanning, a team from King’s College London (KCL) has designed an immersive environment with a special virtual reality (VR) headset for use with MRI…

A pandemic is not a game. Yet, human response in dealing with Covid-19 resembles patterns known from games: people hoard resources, compare leaderboards and graphs, play certain social roles, establish a good-versus-evil narrative, and align themselves with prominent hero figures. The reasoning behind this is simple.

Two clusters of brain cells compete to promote either the persistence or disappearance of traumatic memories, according to a new study conducted in mice. The findings could provide important insights into human conditions such as post-traumatic stress disorder (PTSD), anxiety disorders, and associated problems such as alcohol use disorder (AUD) that can arise from the persistence of traumatic…

Some clinicians are concerned that post-traumatic stress disorder (PTSD) diagnosis has risen throughout Western society since the late 1980s. Is this correct? And if so, has the true incidence of PTSD really spiralled out of control, or has it simply become overdiagnosed? Experts debate the issue in The BMJ this week. PTSD is a serious and uncommon condition resulting from severe trauma, but it…

Every year, millions of children around the world are admitted to hospital for having anaesthesia and surgery. Many of them experience preoperative anxiety which negatively affects both their hospital experience and medical outcome, as well as their future relationships with healthcare services from both a short-term and long-term point of view. A new, internationally aimed website offers…

Increased allergic reactions may be tied to the corticotropin-releasing stress hormone (CRH), suggests a new study. These findings may help clarify the mechanism by which CRH induces proliferation of mast cells (MC) – agents involved in the development of allergies in the human nasal cavity.

A study conducted by Columbia University Mailman School of Public Health researchers reports a high global prevalence of both depression and anxiety during the Covid-19 pandemic. It also shows how the implementation of mitigation strategies including public transportation and school closures, and stay-at-home orders impacted such disorders. Results are published in Psychological Medicine.

During pandemics, protective behaviors need to be motivated by effective communication. A critical factor in understanding a population’s response to such a threat is the fear it elicits, since fear both contributes to motivating protective responses, but can also lead to panic-driven behaviors. Furthermore, lockdown measures affect well-being, making it important to identify protective factors…

A way of using machine learning to more accurately identify patients with a mix of psychotic and depressive symptoms has been developed by researchers at the University of Birmingham. Patients with depression or psychosis rarely experience symptoms of purely one or the other illness. Historically, this has meant that mental health clinicians give a diagnosis of a ‘primary’ illness, but with…

Anorexia is a debilitating eating disorder, and was long thought to be purely psychological. New research is challenging this by revealing that gut microbes may have a significant role in anorexia. A recent review examines the evidence that gut microbes can contribute to anorexia and may provide a new method to treat it.

The identification of people wearing masks has often presented a unique challenge during the pandemic. A new study by researchers from BGU and York University in Canada reveals the impact of this predicament and its potentially significant repercussions. The findings were just published in the journal Scientific Reports.

Patients who need surgery to fix major bone fractures use fewer opioid pills after their procedure if they're reminded of their values – and those reminders don't necessarily need to come from a doctor, according to a new study published in the Journal of Medical Internet Research. “We showed that opioid medication utilization could be decreased by more than a third in an at-risk patient…

Is my heart beating slightly fast? Is a heart attack coming? I didn’t sleep as much as I thought I had last night – is that bad for my heart? Health apps and fitness watches can shed considerable light on how our bodies work and make recommendations for a healthy lifestyle. However, self-measuring can have a downside too, according to a new study that examined the experiences of 27 heart…

Researchers at Aalto University and Turku PET Centre have developed a new method for simultaneous imaging brain activity from two people, allowing them to study social interaction. In a recent study, the researchers scanned brain activity from 10 couples. Each couple spent 45 minutes inside the MRI scanner in physical contact with each other. The objective of the study was to examine how social…

Depression is a common psychiatric disorder and one of the leading causes of disability worldwide. Antidepressants are the first-line treatment for moderate to severe major depressive episodes. Despite their effectiveness, only 40% of patients respond to the first antidepressant they try. A recent paper in Nature Communication strongly suggests that a particular protein, GPR56, is involved in the…

Media reporting of suicide, especially celebrity suicides, is associated with increases in suicide in the general population, particularly by the same method as used by the celebrity, finds an analysis of the latest evidence published by The BMJ. The researchers say their findings support the continued use and promotion of guidelines on responsible media reporting of suicide, especially when…

The coronavirus last week reached the Netherlands and began to spread around the country. How has the Dutch population reacted? What is a useful frame of reference for this situation? And what are the legal guidelines for dealing with the outbreak? Four researchers from the University of Amsterdam – a clinical microbiologist, an anthropologist, a social scientist and a health lawyer – explain…

People who have been treated in intensive care commonly suffer from residual cognitive impairment, but the reason for this is unknown. Researchers at Karolinska Institutet now link cognitive impairment with lasting inflammation and a potential treatment target. The results are presented in the scientific journal Intensive Care Medicine.

The World Health Organization has estimated more than 340 million children and adolescents ages 5-19 are overweight or obese, and the epidemic has been linked to more deaths worldwide than those caused by being underweight. The Centers for Disease Control recently reported an estimated 1 in 5 children in the United States, ages 12-18, are living with prediabetes — increasing their risk of…

A new multicentre study will investigate the link between brain inflammation and psychosis, and use artificial intelligence techniques to identify patients that might benefit most from novel treatments. The study, funded by UKRI Medical Research Council, is led by the Universities of Birmingham and Cambridge. Researchers will examine how and if activated inflammatory cells may act differently in…

Children who suffer repeated febrile convulsions have an increased risk of developing epilepsy and psychiatric disorders such as schizophrenia and depression later in life. This is shown by a comprehensive register-based study from Aarhus University. The risk of febrile convulsions increases with the child’s fever, and approximately four per cent of Danish children suffer from febrile…
