A 2026 Scientific Reports study of Maryland suicide-death records found that an XGBoost machine-learning model could reach 96.1% positive predictive value in hospital-discharge data at the top 0.1% risk threshold, but it still detected only 46.7% of suicide deaths in that cohort. Research Highlights Precision improved at the narrowest threshold: XGBoost reached PPV 0.961 in …
A 300-woman high-risk pregnancy study reported a striking before-after change after 4 weeks of daily Replika chatbot use: Pregnancy Anxiety and Stress Rating Scale scores fell from 54.05 to 10.15, p < 0.001.1 The result is a real signal for digital maternal support, but the no-control design makes it weak evidence that the chatbot itself …
A 745-child cohort found positive MCHAT-R/F autism screens in 22 of 218 children exposed to maternal SARS-CoV-2 infection during pregnancy (10.1%) vs. 30 of 527 pre-pandemic controls (5.7%; p = 0.03).1 The same 2026 analysis added a small serum-proteomics layer: exposed newborns who later screened positive showed altered immune and metabolic markers, but the paper …
A 2026 case-control study found that treatment-naive adults with attention-deficit/hyperactivity disorder (ADHD) had much lower serum SIRT-1, Nrf-2, and HO-1 than matched controls, while TNF-α did not differ. The pattern points more toward impaired antioxidant-defense regulation than a simple broad-inflammation story. Research Highlights Antioxidant-defense markers were lower: adults with ADHD had lower SIRT-1 (9.36 vs. …
A 2026 whole-genome sequencing preprint found rare variant signals in 2 multiplex obsessive-compulsive disorder (OCD) families: an NPY5R missense variant in 10 of 15 affected people in 1 pedigree, plus DLGAP1 and MAPK8IP3 signals that tracked all 3 sequenced cases in a branch of a second pedigree.1 The finding is a candidate-gene result, not a …
A 2026 exploratory analysis of the ABCD cancer dyspnea trial found that higher baseline cytokines predicted less placebo symptom improvement than lower baseline cytokines across 33 of 40 cytokine-symptom combinations at day 7 and 29 of 40 at day 14.1 The signal is not ready for clinical prediction, but it sharpens a trial-design problem: patients …
A 2026 randomized trial in 63 adults with type 2 diabetes found that progressive muscle relaxation was linked to a large fatigue drop in the intervention group, from a Fatigue Severity Scale mean of 51.58 to 34.12, but adjusted between-group tests did not confirm a clear advantage over control for fatigue or sleep quality.1 The …
