Nanosystems for Intranasal Delivery of Therapeutics in Psychiatric Disorders.

Due to the blood-brain barrier (BBB) and issues with oral and other traditional routes of administration, psychiatric disorders present significant challenges in getting therapeutics into the brain. The nose-to-brain pathway, also known as intranasal delivery, has shown promise in overcoming these barriers since it targets the brain directly and bypasses the BBB. This review explores nanocarriers' potential for intranasal delivery of therapeutics in the treatment of psychiatric disorders.

Individualized psychiatric care: integration of therapeutic drug monitoring, pharmacogenomics, and biomarkers.

Personalized treatment optimization considers individual clinical, genetic, and environmental factors influencing drug efficacy and tolerability. As evidence accumulates, these approaches may become increasingly integrated into standard psychiatric care, potentially transforming the treatment landscape for mental health disorders. While personalized treatment optimization shows promise in enhancing therapeutic outcomes and minimizing adverse effects, further research is needed to establish its clinical utility and cost-effectiveness across various psychiatric disorders.

Nasal administration of mitochondria relieves depressive- and anxiety-like behaviors in male mice exposed to restraint stress through the suppression ROS/NLRP3/caspase-1/IL-1β signaling pathway.

Neuroinflammation and oxidative stress are known to be implicated in the pathogenesis of depression. Exogenous mitochondrial transplantation has exhibited beneficial effects for treating neurological disorders. Hence, this research aimed to evaluate the impact of nasal administration of mitochondria on neuroinflammation and oxidative stress in mouse models displaying depressive- and anxiety-like behaviors caused by restraint stress (RS).

Klotho: molecular mechanisms and emerging therapeutics in central nervous system diseases.

Klotho is recognized as an aging-suppressor protein that is implicated in a variety of processes and signaling pathways. The anti-inflammatory, anti-apoptotic, anti-oxidant, and anti-tumor bioactivities of klotho have extended its application in neurosciences and made the protein popular for its lifespan-extending capacity. Furthermore, it has been demonstrated that klotho levels would reduce with aging and numerous pathologies, particularly those related to the central nervous system (CNS).

Efficacy of Rivastigmine Augmentation on Positive and Negative Symptoms, General Psychopathology, and Quality of Life in Patients with Chronic Schizophrenia: A Randomized Controlled Trial.

The study aimed to assess Rivastigmine augmentation on positive and negative symptoms (PNSs), general psychopathology, and quality of life in patients with chronic Schizophrenia. A double-blind, parallel-design, randomized, placebo-controlled trial of 60 schizophrenia patients was conducted. Intervention group received rivastigmine 3 mg/day + Treatment as Usual (TAU) and the control group: TAU + placebo.

MicroRNAs and pro-inflammatory cytokines as candidate biomarkers for recent-onset psychosis.

Background: Recent studies on the schizophrenia spectrum and other psychotic disorders showed that alternation of immune system components, particularly microRNAs (miRNAs) and pro-inflammatory compounds, plays a significant role in developing the illness. The study aimed to evaluate serum expression of the miRNA-26a, miRNA-106a, and miRNA-125b as genetic factors and serum levels of IL-6, IL-1β, and TNF-α as pro-inflammatory factors in an IranianAzeri population.

Methods: Forty patients with recent-onset non-affective psychosis and 40 healthy people as a control group were involved.

Molecular Evaluation of Ex3 VNTR Polymorphism of the DRD4 Gene in Patients With Autism Spectrum Disorder.

Objective: Autism Spectrum Disorders (ASDs) are a group of neurodevelopmental disorders that affect social and communication skills. These diseases are characterized by severe communication and social skills disabilities and limited and repetitive activities. The prevalence of these disorders appears to be steadily increasing.

Assessment of Neuropsychiatric Indicators in Children and Adolescents With Primary Brain Tumors and Other Brain Space-Occupying Lesions Before and After Surgery.

Objectives: Cognitive abilities might be impaired due to brain lesions in children and adolescents. This study aimed to investigate neuropsychiatric indicators in children and adolescents with primary brain tumors and other brain space-occupying lesions (SOLs) before and after the surgical procedure.

Materials & Methods: The current pre-post study was conducted on 81 patients with brain SOLs aged under 18 years hospitalized in the Neurosurgery Ward of Imam Reza university hospital, Tabriz, Iran, within 20 December 2016 to 20 December 2017.

PERSIAN Traffic Safety and Health Cohort: a study protocol on postcrash mental and physical health consequences.

Background: Cohort studies play essential roles in assessing causality, appropriate interventions. The study, Post-crash Prospective Epidemiological Research Studies in IrAN Traffic Safety and Health Cohort, aims to investigate the common health consequences of road traffic injuries (RTIs) postcrash through multiple follow-ups.

Methods: This protocol study was designed to analyse human, vehicle and environmental factors as exposures relating to postcrash outcomes (injury, disability, death, property damage, quality of life, etc).

Assessment of Behavioral Approach and Behavioral Inhibition Systems in Mood Disorders.

Introduction: Psychiatric disorders could be evaluated in terms of behavioral activation and inhibition systems. Dysregulation of these systems may lead to development of manic or depressive episodes in patients with mood disorders. This study aimed to identify Behavioral Approach System (BAS) and Behavioral Inhibition System (BIS) hypersensitivity as the functional brain system behaviors in patients with major depressive disorder and bipolar mood disorder I, compared to healthy individuals.

Efficacy of Self-Hypnosis in Pain Management in Female Patients with Multiple Sclerosis.

Pain is common in patients with multiple sclerosis. This study evaluated self-hypnosis for pain control in that population. A randomized clinical trial was conducted on 60 patients, who were assigned to either a control group or to a self-hypnosis group, in which patients performed self-hypnosis at least 10 times a day.

Knowledge and Attitude of Parents of Children With Attention Deficit Hyperactivity Disorder Towards the Illness.

Background: The knowledge and attitude of parents about attention deficit hyperactivity disorder (ADHD) is a public health issue in which management and rehabilitation approaches may be influenced.

Objectives: The current study aimed to evaluate the knowledge and attitude of the parents of children with ADHD towards this disorder in Tabriz, Iran.

Materials And Methods: The current cross-sectional study evaluated 295 parents of children and adolescents with ADHD referred to psychiatric clinics of Tabriz University of Medical Sciences.

Psychiatric comorbidities in ADHD children: an Iranian study among primary school students.

Background: This study was performed to determine the lifetime prevalence of psychiatric disorders concomitant with attention deficit/hyperactivity disorder (ADHD) among primary school students.

Methods: One thousand six hundred fifty-eight primary school students (781 females and 877 males) were selected in a cluster random manner in 2010. The first screening was performed by the Conner's teacher rating scale revised and Teacher ADHD rating scale-IV and then the students, in whom the ADHD was diagnosed by a child and adolescent psychiatrist according to DSM-IV-TR, were evaluated by K-SADS-PL semi-structured interview to detect the psychiatric comorbidities.

Sexual Knowledge among High School Students in Northwestern Iran.

Objectives. Regarding the importance of sexual desire in adolescence period and public and parental concerns about it and considering the lack of studies on sexual knowledge especially in adolescents in Iran, this study was conducted to evaluate the sexual issues in high school girls and boys. Patients and Methods.

A study on the sources of sexual knowledge acquisition among high school students in northwest Iran.

Background: Considering the importance of sexual drive among teenagers, parental and societal concerns about teenagers' sexual drives, particularly in religious communities such as Iran is of practical importance; therefore, this present research was designed to study students' sources of sexual knowledge acquisition.
