Waving the Bloody Shirt We don’t know who killed Charlie Kirk. We do know who’s trying to exploit his death.

From Paul Krugman

“Whoever did this, there’s just no rational way you can blame this on “the left.”
Also, whatever motivated this murder, it’s simply a fact that over the past decade right-wing extremists have killed many more people than left-wing extremists:”

Mental-health lessons in schools sound like a great idea. The trouble is, they don’t work | Lucy Foulkes All-class therapy sessions don’t help, and may even make matters worse. The evidence shows we need different solutions, says Dr Lucy Foulkes, an academic psychologist at Oxford University

I’m in the Guardian today, arguing that we should stop them all-class mental health lessons in schools

I've thought very carefully about ‘going public’ with this, because it's a sensitive argument to make, especially in the face of so many young people struggling.

Future Proofing Study: a cluster randomised controlled trial evaluating the effectiveness of a universal school-based cognitive–behavioural programme for adolescent depression

This is a *key* new paper in the world of school mental health interventions

A very large trial (N=6388) testing a universal CBT-based app for adolescent depression (13-14y)

No effects found (on depression, anxiety, distress or insomnia)

Publications on #hoarding vs #OCD. Quite shocking how little we know about hoarding.

After 5 yrs in planning, our Lancet Commission on self-harm now published.

Self-harm affects millions of people globally, yet sadly it remains stigmatised & neglected. For too long, people who self-harm have not received the compassionate and tailored support that they deserve.

Transmission of Mental Disorders in Adolescent Peer Networks This cohort study examines the transmission of mental disorders among adolescents observed in follow-up after school exposure to 1 or more classmates

1/3
New Jama Psychiatry paper finds if your classmates have a mental disorder, you're more likely to get one later in life.

They conclude that mental disorders are *socially contagious*.

I think it's much more plausible that authors didn't control for all relevant confounders.

The effect of health-care privatisation on the quality of care Over the past 40 years, many health-care systems that were once publicly owned or financed have moved towards privatising their services, primarily through outsourcing to the private sector. But what ...

“We also found that aggregate increases in privatisation frequently corresponded with worse health outcomes for patients.”

Will donate €200 to charity of your choice if we can identify the study where the brain image comes from. Journalists have used the PET scan image from some stock footage for decades, creating and perpetuating false / harmful impressions.

Fixing this starts w finding source.

Trying to figure out why #hoarding has historically been considered to be #OCD leads one to reading some really messed up stuff.

New systematic review & meta-analysis of ketamine for PTSD finds only consistent significant effect at 24 hrs post infusion. Effect significantly better than passive control but not active control conditions. Raises questions about why this is considered promising

Gaza reports more than 11,100 killed. That’s one out of every 200 people.

Gaza reports more than 11,100 killed. That’s one out of every 200 people.

One out of every 200 people in Gaza have been killed by the Israeli army — and the bombing still hasn’t stopped.

Let that sink in for a moment, then remember how Israeli authorities are trying to make Western publics believe they aren’t targeting civilians. This is a massacre.
