The present study assessed 108 women enrolled in a residential treatment program for perinatal substance abusers in order to examine possible subtypes based on current alcohol, other drug and psychiatric problem severity. Most participants were African-American (81%), unmarried (91%), unemployed (97%), high school graduates (63%) with a mean age of 30 years. The primary substances of abuse were cocaine/crack (87%) and opiates (9%). The majority (79%) of subjects were also nicotine dependent. Drug severity did not distinguish between these groups; however, when cluster analysis was applied to ASI alcohol and psychiatric composite scores, three clusters emerged: (1) high alcohol, drug, and psychiatric problem severity (57%); (2) high drug and psychiatric problem severity (20%); and (3) high drug severity only (23%). Neither current nor childhood demographic characteristics differed among the three groups. However, significant differences were found among selected childhood risk factors, including perceived quality of relationships with family, age of onset of substance use, childhood abuse history, and family history of mental illness. These results emphasize the need for careful assessment and treatment planning that addresses the unique needs of these women.

Preliminary Evidence for Perturbation-Based tACS-EEG Biomarkers of Gamma Activity in Alzheimer's Disease.

Background: Alzheimer's disease (AD) is characterized by impaired inhibitory circuitry and GABAergic dysfunction, which is associated with reduced fast brain oscillations in the gamma band (γ, 30-90 Hz) in several animal models. Investigating such activity in human patients could lead to the identification of novel biomarkers of diagnostic and prognostic value. The current study aimed to test a multimodal "Perturbation-based" transcranial Alternating Current Stimulation-Electroencephalography (tACS)-EEG protocol to detect how responses to tACS in AD patients correlate with patients' clinical phenotype.

To explore the effect of lithium carbonate combined with olanzapine on glucose and lipid metabolism, as well as gender differences in treating bipolar disorder (BD). 110 BD patients admitted to the Fifth People's Hospital of Luoyang from February 2022 to January 2024 were retrospectively included in the study. Patients were categorized into two groups based on treatment: The single group (lithium carbonate, n = 50) and the coalition group (lithium carbonate + olanzapine, n=60).

The objective of this study was to evaluate the therapeutic effects of Chiglitazar combined with Rosa roxburghii Tratt (RRT) in inpatients diagnosed with psychiatric disorders and antipsychotic-induced metabolic syndrome (MetS).100 cases were included and divided into the Siglitazar group (n=50) and the Siglitazar + RRT group (n=50) Anthropometric measurements, lipid and glucose metabolism indicators, inflammatory markers and PANSS scores were assessed at baseline, 8 weeks and 12 weeks post-treatment. Both treatment groups exhibited significant reductions in waist circumference and improvements in lipid profiles and glucose metabolism indicators over the 12-week study period.

Article Synopsis
- Depression treatment effectiveness differs greatly among individuals, highlighting the need for objective biomarkers that can accurately predict therapy outcomes to improve treatment efficiency.
- This study used functional near-infrared spectroscopy (fNIRS) combined with clinical assessments to explore whether machine learning techniques could forecast treatment responses in patients with major depressive disorder (MDD).
- Findings revealed that changes in total hemoglobin levels in a specific brain region (dlPFC) correlated significantly with treatment response, and the fNIRS-only model demonstrated better predictive accuracy compared to a model that also included clinical data.
N-terminal fragment shedding contributes to signaling of the full-length adhesion receptor ADGRL3.

Most adhesion GPCRs undergo autoproteolytic cleavage during receptor biosynthesis, resulting in non-covalently bound N- and C-terminal fragments (NTF and CTF) that remain associated during receptor trafficking to the plasma membrane. While substantial evidence supports increased G protein signaling when just the CTF is expressed, there is an ongoing debate about whether NTF removal is required to initiate signaling in the context of the wild-type receptor. Here, we use adhesion GPCR latrophilin-3 (ADGRL3) as a model receptor to investigate tethered agonist-mediated activation.
