Toward Coordinated Systems of Care for TIA—The Role and Scope of EDs https://jamanetwork.com/journals/jamaneurology/fullarticle/2855738 In this issue of JAMA Neurology, Mamer and colleagues present national trends in the emergency department (ED)–based care of transient ischemic attack (TIA) from 2013 to 2021. The authors demonstrate remarkable increases in the rate of advanced imaging in the ED and decreases in the hospitalizations of this population. The marked increase in use of vascular imaging is reassuring to see, as the timely identification of significant atherosclerotic disease—especially carotid stenosis requiring revascularization—is a key step in lowering the risk of early recurrent stroke.

Error in Byline https://jamanetwork.com/journals/jamaneurology/fullarticle/2855739 The Original Investigation titled “Efficacy and Safety of Gefurulimab in Generalized Myasthenia Gravis: The PREVAIL Phase 3 Randomized Clinical Trial,” published online July 27, 2026, and in the September issue, was corrected to add the study group to the byline and a supplement listing the nonauthor collaborators. This article was corrected online.

Errors in Text, Table 1, Figures 1 to 3, and Supplements https://jamanetwork.com/journals/jamaneurology/fullarticle/2855740 In the Original Investigation titled “Effect of Electroacupuncture on Postherpetic Neuralgia: A Randomized Clinical Trial,” published online first on May 26, 2026, and in the July 2026 issue, there were errors in the article text, Table 1, Figures 1 and 3, and the caption of Figure 2; the protocol in Supplement 1; and eTables 2, 4, 7, 12, and 14, footnote d of eTable 5, and the captions for eFigures 1 and 2 in the original Supplement 2 (now Supplement 3).

Interpretation of Between-Group Differences in Regard to Minimal Clinically Important Differences https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2855602 To the Editor We were interested to read the randomized clinical trial by Bronfort et al that evaluated clinician-supported biopsychosocial self-management (SSM) for preventing chronic low back pain (LBP). The study addresses an important gap in secondary prevention and provides valuable long-term comparative data.

Medication for Alcohol Use Disorder Awareness and Attitudes https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2855603 This survey study evaluates whether US adults are aware of and agree with the use of medication for alcohol use disorder in a national probability-based survey.

Preventing Acute Stress in the Operating Room—Is Oxytocin Ready? https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2855604 Acute stress symptoms are common after traumatic injury and emergency surgery, are associated with later posttraumatic stress disorder, and have no established pharmacological prevention. In this issue of JAMA Internal Medicine, Huang and colleagues report a single-center, double-blind, randomized clinical trial in which 328 adults undergoing emergency surgery for incidental fracture received a single 40-IU dose of intranasal oxytocin or saline 10 minutes before induction of anesthesia. The primary outcome, a first positive screening result for probable acute stress disorder on the Stanford Acute Stress Reaction Questionnaire (SAS-RQ; score ≥40) within 3 postoperative days, occurred in 15.9% of the oxytocin group and 30.5% of the saline group (risk difference, −14.6 percentage points; 95% CI, −23.5 to −5.5; adjusted hazard ratio, 0.45; 95% CI, 0.27-0.75). Oxytocin was also associated with lower salivary levels of cortisol and malondialdehyde and a smaller decrease in superoxide dismutase levels, whereas anesthetic exposure, analgesic consumption, pain, and cognitive scores did not differ between groups, and no serious adverse events occurred. The authors concluded that preoperative intranasal oxytocin may be a feasible perioperative strategy for preventing acute stress symptoms but acknowledged that the outcome was a screening measure rather than a clinical diagnosis, no preoperative psychological baseline was obtained, follow-up ended at 72 hours, and the biomarker findings were correlates rather than evidence of a mechanism.

Orforglipron for Type 2 Diabetes and Pancreatic Risk Assessment https://jamanetwork.com/journals/jama/fullarticle/2855798 To the Editor The recent ACHIEVE-5 trial reported that the oral, nonpeptide glucagon-like peptide-1 (GLP-1) receptor agonist orforglipron, when added to titrated insulin glargine, lowered hemoglobin A1c by 1.03 to 1.08 (95% CI, 0.77-1.33) percentage points vs placebo at 40 weeks for both primary dosages (P < .001 for each). We would like to highlight the pancreatic enzyme data presented in eTable 7 in the article’s Supplement 1, which we believe were underrepresented in the discussion.

Treatment Approach to Major Depressive Disorder https://jamanetwork.com/journals/jama/fullarticle/2855799 Randomized clinical trials (RCTs) of psychedelic drugs such as psilocybin and lysergic acid diethylamide (LSD) have shown that these drugs have dramatic antidepressant effects in patients with difficult-to-treat depression. An important limitation of these drugs is that the psychedelic effects are also strong and require careful, time-intensive management by an experienced treatment team. Studies are now examining whether new formulations of psychedelics can have strong antidepressant action without the need for such intensive management. Mebufotenin, a 5-hydroxytryptamine 1A (5-HT1A) and 5-HT2A receptor agonist that is naturally found in toad venom, is one example of such a psychedelic drug.

Service Use After Introduction of AI-Enabled Prior Authorization in Medicare https://jamanetwork.com/journals/jama/fullarticle/2855989 This study uses Epic Cosmos data to assess changes in use of medical services by Medicare recipients after the implementation of artificial intelligence–enabled prior authorization requirements under the Center for Medicare & Medicaid Innovation WISeR (Wasteful and Inappropriate Service Reduction) model.

SGLT2 Inhibitor Use and Levels of Hemoglobin, Markers of Iron, and Erythropoiesis https://jamanetwork.com/journals/jama/fullarticle/2855788 This meta-analysis of clinical trials of sodium-glucose cotransporter 2 (SGLT2) inhibitors examines the association of SGLT2 use with increases in levels of hemoglobin and hematocrit.

Increased Hemoglobin With SGLT2 Inhibitors https://jamanetwork.com/journals/jama/fullarticle/2855789 Inhibitors of the sodium-glucose transporter 2 (SGLT2i) were developed to improve metabolic control of diabetes by inducing urinary glucose excretion. When tested for cardiovascular safety, use of SGLT2i surprisingly showed improvements in cardiovascular and kidney outcomes. SGLT2 inhibitors have now become firmly established as guideline-recommended therapy in patients with diabetes and high cardiovascular risk, in patients with heart failure, and in those with chronic kidney disease (CKD).

Trastuzumab Rezetecan in ERBB2-Low Advanced Breast Cancer https://jamanetwork.com/journals/jama/fullarticle/2855791 This randomized, multicenter, phase 3 trial compares progression-free survival with trastuzumab rezetecan vs physician’s choice of chemotherapy in patients with ERBB2-low metastatic breast cancer.

Trastuzumab Rezetecan in EBBR2-Low Metastatic Breast Cancer https://jamanetwork.com/journals/jama/fullarticle/2855792 Antibody-drug conjugates (ADCs) combine the tumor-targeting specificity of a monoclonal antibody with a cytotoxic payload, using a chemical linker designed to remain stable in the bloodstream and to release the drug selectively within tumor cells. Third-generation ADCs can exert a bystander effect, whereby the payload diffuses into neighboring tumor cells, killing them independently of target expression. The drug to antibody ratio further modulates potency and tolerability. ADCs have transformed the life expectancy of patients with erythroblastic oncogene B (ERBB2; formerly HER2/neu)–overexpressing breast cancer and are rapidly expanding into new tumor types and molecular subgroups.
