The aim of this pilot study was to evaluate the effectiveness of two specialized Australian PTSD assistance dog programs in reducing PTSD and mental health symptoms over a one-year period. A total of 44 participants who were partnered with an assistance dog were analysed. Using an intent to treat analysis, compared to the baseline measures, all mental health outcomes exhibited statistically significant reductions in scores at the 3-month follow-up, and persisted at the 6-month, and 12-month follow-up. When comparing baseline to 3-month follow-up the effect size (Cohen's d) was strongest for stress (d = 0.993), followed by PTSD (d = 0.892), anxiety (d = 0.837). Analyses among those who also completed the waitlist-baseline assessment (n = 23) showed slight reductions in stress and depression prior to receiving their dog (whilst waiting for their dog). However, larger reductions were yielded across all mental health measures when comparing waitlist-baseline to 3-month follow-up.

Background: The inheritance of the short allele, encoding the serotonin transporter (SERT) in humans, increases susceptibility to neuropsychiatric and metabolic disorders, with aging and female sex further exacerbating these conditions. Both central and peripheral mechanisms of the compromised serotonin (5-HT) system play crucial roles in this context. Previous studies on SERT-deficient (Sert) mice, which model human SERT deficiency, have demonstrated emotional and metabolic disturbances, exacerbated by exposure to a high-fat Western diet (WD).

Background: α thalassemia/mental retardation syndrome X-linked (ATRX) serves as a part of the sucrose nonfermenting 2 (SNF2) chromatin-remodeling complex. In interphase, ATRX localizes to pericentromeric heterochromatin, contributing to DNA double-strand break repair, DNA replication, and telomere maintenance. During mitosis, most ATRX proteins are removed from chromosomal arms, leaving a pool near the centromere region in mammalian cells, which is critical for accurate chromosome congression and sister chromatid cohesion protection.

Background: We aimed to assess impairments on health-related quality of life, and mental health resulting from Retinal artery occlusion (RAO) with monocular visual field loss and posterior circulation ischemic stroke (PCIS) with full or partial hemianopia using patient-reported outcome measures (PROMs).
Methods: In a prospective study, consecutive patients with acute RAO on fundoscopy and PCIS on imaging were recruited during their surveillance on a stroke unit over a period of 15 months. Baseline characteristics were determined from medical records and interviews.
Frequent Alcohol Use of Adolescents in Low-Income Families: Application of the Multiple Disadvantage Model.
Subst Use Misuse

Defense Personnel and Security Research Center, Peraton, Seaside, California, USA.
Background: This study investigated relationships between low-income adolescent drinkers' frequent alcohol use and five factors: social disorganization, social structural, social integration, mental health, and access to healthcare.
Objective: A sample of 1,256 low-income adolescent drinkers and caregivers were extracted from the Future of Families and Child Wellbeing Study.
Results: Logistic regression yielded results showing adolescent drinkers' weekly drinking to be associated positively with Hispanic adolescents, drinking peers, adolescents' depression/anxiety, and caregiver's daily drinking.
