A 99-patient randomized trial found that adding esketamine to sufentanil patient-controlled analgesia lowered postoperative depression and anxiety scores at 24 and 72 hours after colorectal cancer surgery, while resting and activity pain scores did not differ by group.1 That pattern makes the result more interesting than simple pain relief: the mood signal was partly independent …
A 2026 review of electroacupuncture for depression found a familiar split: mechanistic evidence is rich, but clinical proof remains uneven because representative trials ranged from 65 to 270 participants, used different sham or drug comparators, and often failed to connect stimulation parameters with biological endpoints.1 Electroacupuncture is plausible as a subtype-matched neuromodulation strategy, but it …
A 2026 multimodal MRI study found that treatment-resistant depression had lower coordination between brain structure and brain activity than non-treatment-resistant depression in frontal, parietal, motor, and temporal regions. Machine-learning models using those structure-function coupling measures classified treatment-resistant vs. non-treatment-resistant depression with AUC values from 0.886 to 0.950 in the primary atlas analysis.1 Research Highlights TRD …
