Psychotherapy for Impact of Killing During War: A Randomized Clinical Trial

Maguen S, Gloria R, Lehrner A, et al. · JAMA Psychiatry · August 2026

This multisite VA trial randomized 100 veterans with PTSD and distress over killing or feeling responsible for deaths in war to Impact of Killing (IOK), a manualized therapy addressing killing-related cognitions, self-forgiveness, and moral repair, versus present-centered therapy, with blinded assessors through 6-month follow-up. Both treatments improved functioning, but IOK produced significantly greater gains on work/social/family functioning and greater reductions in PTSD and moral-injury symptoms than present-centered therapy.

💡 Why it matters

This gives clinicians a manualized, evidence-based psychotherapy that directly targets moral injury from killing — a driver of distress that standard trauma-focused PTSD therapies don't always address head-on.

Neurological Manifestations in Adult Survivors of Ebola Virus Disease

Billioux BJ, Reilly C, van Ryn C, et al. · JAMA Neurology · August 2026

This NIH-affiliated natural history study followed 148 Ebola virus disease survivors in Liberia for more than 7 years against 81 antibody-negative contacts, using biannual standardized neurological exams. Survivors had markedly higher rates of cognitive dysfunction (56%), persistent headaches (66%), and depression (49%) than controls, with memory loss persisting in 57% of survivors at final follow-up versus 26% of controls. Most symptoms improved over time, but a substantial minority carried durable impairment nearly a decade after infection.

💡 Why it matters

Almost half of Ebola survivors had depression alongside objective memory deficits at long-term follow-up — a striking, non-COVID example that a severe systemic viral infection can produce durable post-infectious neuropsychiatric illness worth asking about whenever mood or cognitive symptoms follow a serious infection.

Psychiatric Fact

Clozapine's Level Can Swing With a Coffee Habit, Not Just a Cigarette One

Every resident learns that smoking induces CYP1A2 and that clozapine levels can climb dangerously when a patient quits on admission — fewer remember that caffeine is a competitive CYP1A2 inhibitor working in the opposite direction. The effect is dose- and person-dependent: controlled dosing raised levels by roughly 19% in healthy volunteers, but case reports describe swings up to 97% and at least one instance of severe toxicity with multiorgan failure tied to a caffeine binge. It's a far weaker inhibitor than fluvoxamine, which produces a 5- to 10-fold rise — so this isn't a reason to ban coffee, but it is a reason to ask about caffeine intake with the same reflex used for smoking, especially around a hospital admission that abruptly changes a patient's usual access to either one.

Psychotherapy Teaching Pearl

Chain Analysis Finds the Vulnerability, Not Just the Trigger

A DBT behavioral chain analysis is often taught as “find the trigger,” but the more clinically useful target is the vulnerability factor — the upstream condition, like sleep deprivation, a skipped meal, an earlier invalidating exchange, or substance use, that lowered the patient's threshold before the proximal trigger ever landed. Two chains with an identical trigger, like a critical text from a partner, can produce entirely different outcomes depending on what vulnerability preceded it. Stopping the analysis at the trigger teaches the patient to avoid triggers, which is both impossible and beside the point; locating the vulnerability factor teaches them to intervene upstream, where change is actually available. The chain should move backward in time until it finds the first point where a different choice was realistically possible.

🗒️ Vignette

A patient reports a self-harm episode “triggered” by her mother's comment at dinner. Chaining backward, the therapist learns she'd slept three hours, skipped both prior meals, and had fought with a roommate that morning — none of which she'd connected to the evening's collapse. The intervention isn't “how do you cope with critical comments,” the trigger; it's “what needs to change about your Tuesday mornings so a comment like that doesn't land on an empty tank.” The skill deficit being solved is upstream self-care, not in-the-moment distress tolerance.
