Background: Although repeatedly confirmed, the molecular nature of gene-environment (GxE) interactions has rarely been investigated in the clinical context of mood disorders. This study assesses the relationship between HTR2A genetic variants and the modulatory effect of inflammation in a collective cohort of patients with major depressive disorder (MDD) and bipolar disorder (BD), as a unified group with two distinct phenotypes.
Methods: The study included 138 patients with acute mood episodes (BD = 83; MDD = 55).
Innovative treatments for spinal muscular atrophy (SMA) yield the utmost advantages only within the presymptomatic phase, underlining the significance of newborn screening (NBS). We aimed to establish statewide NBS for SMA in Serbia. Our stepwise implementation process involved technical validation of a screening assay, collaboration with patient organizations and medical professionals, a feasibility study, and negotiation with public health representatives.

Methods: We conducted a longitudinal prospective study to evaluate pNF-H levels in the cerebrospinal fluid (CSF) and plasma of 29 individuals with childhood-onset SMA treated with Nuinersen (SMA type 1: = 6, 2: = 17, 3: = 6). pNF-H levels before and during treatment were compared with the levels of controls ( = 22), patients with Duchenne muscular dystrophy ( = 17), myotonic dystrophy type 1 ( = 11), untreated SMA individuals with chronic type 3 disease ( = 8), and children with presymptomatic SMA ( = 3).
