Reading of the Week: Cannabis in America (and Canada) – the New JAMA Psychiatry Paper with Commentary

November 21, 2019 /

From the Editor

It’s legal. Are people using more? And has cannabis use disorder become more common?

This week, we look at a new paper considering cannabis legalization and use. The authors draw on American data where legalization is increasingly found across different states though not as extensively as in Canada; to date, 11 US states have legalized recreational cannabis, with 33 (and D.C.) having legalized medical marijuana.

In a new JAMA Psychiatry paper, Magdalena Cerdá and her co-authors use the National Survey on Drug Use, a major survey involving more than half a million participants, considering marijuana use, frequent use, and cannabis use disorder. What effect does legalization have? They find that cannabis use disorder is more common in adolescents after legalization and for adults who are 26 years of age and older, use, frequent use, and substance use are all up.

We consider the paper. We also discuss the commentary that accompanies it. Finally, with an eye closer to home, we ask: are the findings relevant here in Canada?

Reading of the Week: Are the Pills Safe? JAMA Psychiatry on Antidepressants, NICE on Withdrawal Symptoms

October 31, 2019 /

From the Editor

They are popular, but are they safe?

It’s the question that patients often ask about antidepressants. Though SSRIs have been on the market for decades – and older antidepressants for much longer – people continue to question their overall safety. Online forums relate stories of problems; news articles have linked them to suicidal thoughts in youth and other issues; regulatory agencies have acted on their doubts – the FDA, as an example, issued a black box warning for SSRIs use in adolescents.

This week, in our first selection, we consider a new paper from Linköping University’s Elena Dragioti and her co-authors. In this JAMA Psychiatry paper, the authors use a systematic umbrella review, drawing on meta-analyses of observational studies. “This study’s findings suggest that claimed adverse health outcomes associated with antidepressants may not be supported by strong evidence and may be exaggerated by confounding by indication; no absolute contraindication to the use of antidepressants was found to be currently supported by convincing evidence.”

We discuss the paper and the methodology.

In the second selection, we draw from the recently revised UK NICE guideleines, which provide advice on withdrawal symptoms and tapering strategies. “There is substantial variation in people’s experience…”

Reading of the Week: Can Machine Learning Improve Psychotherapy? The New JAMA Psychiatry Paper; Also, Santa Ono on His Mental Illness

September 12, 2019 /

From the Editor

“Compared with treatment of physical conditions, the quality of care of mental health disorders remains poor, and the rate of improvement in treatment is slow. Outcomes for many mental disorders have stagnated or even declined since the original treatments were developed.”

Are there two sentences more disappointing to read? One in five Canadians will experience a mental health problem this year – and yet we have basic problems with quality (and access).

Could AI and machine learning help?

In the first selection, we consider a new JAMA Psychiatry paper which opens with the two sentences above. The University of Cambridge’s Michael P. Ewbankand his co-authors don’t simply bemoan the status quo but seek to change it – they “developed a method of objectively quantifying psychotherapy using a deep learning approach to automatically categorize therapist utterances from approximately 90  000 hours of [internet-delivered CBT]…” In other words, by breaking therapy down into a couple of dozen techniques and then employing machine learning, they attempt to match techniques with outcomes (patient improvement and engagement), with an eye on finding what works and what doesn’t. And, yes, you read that right: they drew on 90 000 hours of therapy. They show: “factors specific to CBT, as well as factors common to most psychotherapies, are associated with increased odds of reliable improvement in patient symptoms.”

In the second selection, we consider the comments of University of British Columbia President Santa Ono about school and the stresses of school. Ono speaks about his own struggle with depression. “I’ve been there at the abyss.”

Reading of the Week: Behavioural Economics & Mental Illness – the New JAMA Psychiatry Paper; Also, the Strange History of Lithium

September 5, 2019 /

From the Editor

Can we nudge people to better choices? Economists, psychologists, and psychiatrists have all considered this idea. Though early work looked at pensions and finance, more recent studies in behavioural economics have considered topics in health care, like helping smokers quit.

This week, we open with a new paper that considers the concept of delay discounting in people with major mental illness. “Delay discounting” is a clunky term for the value that people place on rewards over time. Take two individuals, Paul and Peter, offered the same deal: they can be given $100 today or $200 in three months – Paul wants the $100 now while Peter is willing to wait for the bigger reward of $200. Paul, then, has more delay discounting than Peter.

Existing literature shows delayed discounting for people who have addiction and ADHD diagnoses. But what about others with mental disorders? McMaster University’s Michael Amlung and his co-authors study delay discounting by doing a meta-analysis, pulling data from 43 studies involving eight psychiatric disorders in this new JAMA Psychiatry paper. “To our knowledge, this meta-analysis is the first quantitative synthesis of delay discounting findings in psychiatric disorders, except ADHD and addictive disorders. This meta-analysis provides relatively strong evidence that delay discounting is a transdiagnostic process in psychiatric disorders.”

In our second selection, we consider a longer essay on lithium for bipolar and its first champion. The University of Groningen’s Douwe Draaisma, a professor of the history of psychology, writes about urine, guinea pigs, and the beginning of the psychopharmacological era.

Reading of the Week: PTSD & Treatment – What’s Evidence Based? JAMA Psychiatry’s New Network Meta-analysis

August 8, 2019 /

From the Editor

Just over a century ago, Dr. Charles Myers wrote “A Contribution To The Study Of Shell Shock” in The Lancet, the first paper on shell shock. Today, our understanding of PTSD has greatly evolved.

But what’s the most effective treatment for people with PTSD?

This week, we consider the new paper by the University of Basel’s Jasmin Merz and her co-authors. They use a network meta-analysis to determine whether patients do better with medications, psychotherapy, or both; in other words, they attempt to analyze different studies in this area, but not necessarily those that do direct comparisons (that’s my Twitter-length biostatistical summary). They find: “The available evidence is sparse and appears not to support the use of pharmacological therapy as first-line treatment for posttraumatic stress disorder…”

We also consider an editorial that runs with the study. Murray B. Stein and Sonya B. Norman, both of University of California San Diego, are critical, commenting that aspects of the study may be “hard to swallow.”

Reading of the Week: Cutting-Edge Care – Esketamine for Depression (NEJM), Digital Psychiatry for Suicide Prevention (JAMA Psych), Asylums for All (AJP)

July 18, 2019 /

From the Editor

This time of year, many doctors take to social media to offer advice to young colleagues as they start their specialty training (#TipsForNewDocs). Generally, the tweets give solid suggestions on everything from the importance of mentorship to doing regular exercise. For those new grads beginning psychiatry training, I offer: read more, the field is evolving. Since I started my psychiatry residency 19 years ago this month, we have seen new antidepressants placed into the drug cabinets of our patients, mental-health apps populate their smart phones, and clinical guidelines enter our practices, helping us better manage their mental illness.

This week’s Reading focuses on cutting-edge care, and there is plenty to read.

In our first selection, we consider a new paper from The New England Journal of Medicine. Written by Dr. Jean Kim and four other FDA officials, the authors discuss esketamine for depression. “The drug represents an important addition to the treatment options for patients with treatment-resistant depression.”

nasal-spray-sEsketamine: from club drug to depression care

In our second selection, Dr. John Torous (of Harvard Medical School) and Rheeda Walker (of the University of Houston) consider digital psychiatry and suicide prevention, reviewing the field with cautious optimism. The paper opens with a single sentence that puts these efforts in perspective: “Because the rates of suicide attempts and deaths have recently increased to 50-year highs,new solutions are needed.”

And, in our third selection, we look at a not-so-new editorial from The American Journal of Insanity that calls for better treatment of the poor.

Enjoy.

Reading of the Week: Many Medications, Better Outcomes? Paul Kurdyak on the New JAMA Psychiatry Paper Considering Antipsychotics and Schizophrenia

May 23, 2019 /

From a Contributing Editor

For individuals with schizophrenia who are failed by trials of single antipsychotics, what’s next?

This week, we discuss a paper that addresses a treatment controversy. Antipsychotic polypharmacy (the use of more than one antipsychotic) is generally discouraged because the efficacy evidence is weak, and there is risk of increasing adverse events and effects with the addition of a second antipsychotic. Choosing Wisely is an initiative that seeks to advance a national dialogue on avoiding unnecessary medical tests, treatments and procedures; among their psychiatric recommendations is to avoid the use of multiple antipsychotics. The American Psychiatric Association contributed this to the Choosing Wisely initiative:

Research shows that use of two or more antipsychotic medications occurs in 4 to 35% of outpatients and 30 to 50% of inpatients. However, evidence for the efficacy and safety of using multiple antipsychotic medications is limited, and risk for drug interactions, noncompliance and medication errors is increased. Generally, the use of two or more antipsychotic medications concurrently should be avoided except in cases of three failed trials of monotherapy, which included one failed trial of Clozapine where possible, or where a second antipsychotic medication is added with a plan to cross-taper to monotherapy.

 This is where this week’s selection comes in. The study, “Association of Antipsychotic Polypharmacy vs Monotherapy With Psychiatric Rehospitalization Among Adults With Schizophrenia,” is from Finland by Karolinska Institutet’s Jari Tiihonen and his colleagues. This paper uses Finnish population-based health administrative data to evaluate the association between antipsychotic polypharmacy and psychiatric hospitalization. They conclude: “These results indicate that rational antipsychotic polypharmacy seems to be feasible by using 2 particular antipsychotics with different types of receptor profiles.”

Reading of the Week: Can Social Connectedness Prevent Suicides? The New JAMA Psychiatry Paper on Caring Contacts in the Military

May 16, 2019 /

From the Editor

Social disconnectedness contributes to suicide. Past studies have tried to connect with people at risk, using simple tools like postcards.

This week, we look at a JAMA Psychiatry paper. The University of Washington’s Katherine Anne Comtois and her co-authors use a text message-based intervention (Caring Contacts) to try to reduce suicidal thoughts and behaviours in active military personal. They find: “Although the primary hypotheses were not supported, Caring Contacts was found to be a simple, scalable intervention that may be effective in reducing the occurrence of suicide ideation and attempts.”

We consider the paper and two editorials. We also consider a New York Times essay that asks: “If suicide is preventable, why are so many people dying from it?”

Reading of the Week: CBT for Depression – What Really Works? The New JAMA Psychiatry Paper

April 25, 2019 /

From the Editor

“It changed my life.”

A few years ago, a patient described to me how helpful cognitive behavioural therapy was for him. CBT wasn’t his only treatment – he had a couple of medication trials – but he found the psychotherapy to be very helpful.

Others have had a similar experience, but CBT isn’t widely available in Canada; Puyat et al. found in a Canadian Journal of Psychiatry paper that the vast majority of people with depression don’t receive any form of psychotherapy or counseling. How can we address this access gap? Could different forms of CBT work including those that are less resource intensive? What to make of self-help?

In this Reading, we consider a new paper by Vrije Universiteit Amsterdam’s Pim Cuijpers and his co-authors that seeks to answer these questions. They use a network meta-analysis to compare five treatment formats with each other and control conditions (waiting list, care as usual, and pill placebo). Their conclusion: “This study suggests that group, telephone, and guided self-help treatments are effective interventions that may be considered as alternatives to individual CBT.”

Reading of the Week: Cancer and Suicide – the New JAMA Psychiatry Paper

April 11, 2019 /

From the Editor

When I worked closely with cancer patients, we would often speak of that moment – the moment they were diagnosed, when they officially became cancer patients. Many recalled their first emotions: the disbelief, the shock, the anger. A few could even tell me sparkling details, like the way the doctor looked at them or what she was wearing. And, for all, that moment had been life altering.

That moment is followed by challenges, and for some, depression and even suicide.

What is the risk of suicide after the cancer diagnosis? In this week’s Reading, we look at a new JAMA Psychiatry paper. Drawing on English data, and involving 4.7 million people, Public Health England’s Katherine Henson and her co-authors look at cancer and suicide. They find: “Despite low absolute numbers, the elevated risk of suicide in patients with certain cancers is a concern, representing potentially preventable deaths.”

In this Reading, we consider the paper on this important topic, as well as an editorial.
