Background/aim: To detect specific molecular changes of DNA level in primary autism patients by using whole genome CGH array technology.
Materials And Methods: A cohort of 35 primary autism patients received clinical genetic testing by using an oligonucleotide-based CGH array platform to test for submicroscopic genomic deletions and duplications. Fluorescent in situ hybridization was performed in seven patients for confirmation of the results.
Results: We found 16p13.11 deletion in thirteen patients, 16p11.2 deletion in twelve patients, 1q21.1 deletion in ten patients, 2q21.1q21.2 deletion in eight patients, and 8p23.1 deletion in seven patients.
Conclusion: Our study indicates that genes in 16p13.11, 16p11.2, 1q21.1, 2q2l.1q21.2, and 8p23.1 loci are potential predisposition and new suspicious regions for primary autism. Deletion's in these regions should be investigated in further studies to understand pathogenesis of primary autism.

Background: Maternal smoking around birth (MSAB) and early-life breastfeeding (BAB) represent critical factors that may exert enduring effects on neuropsychiatric health. Although previous research has examined these exposures separately, the combined impact of both on disorders such as ADHD, ASD, BD, MDD, ANX, and SCZ remains unclear. This study aims to evaluate the causal relationships between MSAB and BAB and the risk of developing these neuropsychiatric disorders through Mendelian randomization (MR) analysis.

Background: Medical marijuana (MMJ) is available in Pennsylvania, and participation in the state-regulated program requires patient registration and receiving certification by an approved physician. Currently, no integration of MMJ certification data with health records exists in Pennsylvania that would allow clinicians to rapidly identify patients using MMJ, as exists with other scheduled drugs. This absence of a formal data sharing structure necessitates tools aiding in consistent documentation practices to enable comprehensive patient care.
