Serum Galanin in Children with Autism Spectrum Disorder.

Recent studies have attempted to measure several biomarkers to understand the complex interactions of the anatomic systems that may be involved in autism spectrum disorder (ASD). In CNS, galanin takes part in a variety of pathological and physiological processes. Prior research has indicated it is involved in several neuropsychiatric disorders and has a role in inhibiting the neuronal firing and release of serotonin, norepinephrine, and acetylcholine. To date, serum galanin levels have not been investigated in the context of ASD. This study aimed, therefore, to compare the serum galanin levels of children with ASD and healthy controls and to reveal any association between galanin level and the severity of ASD, as well as other psychological and demographic parameters. Serum galanin levels were measured by radioimmunoassay in 116 children with ASD and 98 healthy children. We observed significantly increased serum concentrations of galanin in children with ASD relative to healthy children. Moreover, children with severe ASD had significantly higher galanin levels than those with less severe disease. We also confirmed significant positive correlations between galanin and psychiatric parameters in children with ASD. For the first time, we suggest a possible correlation between serum galanin and the degree of ASD severity. Increased galanin levels may play a role in the pathogenesis of ASD.

Neonatal Microbiome: Is it Still Beneficial?

The neonatal microbiome includes all the microorganisms living within or on the surface of the newborn, as well as their genes (i.e., bacteria, fungi, and viruses), which are composed mainly of bacteria. The majority of these microorganisms reside in the gastrointestinal tract (GIT), which is known as the gut microbiome. They include trillions of microbes, which exceed the total number of neonate cells. In this study, we have examined factors affecting neonatal microbiome colonization, various phyla of the microbiome in neonates, and their characteristics. In addition, we have discussed symbiosis and dysbiosis, precipitating diseases, breast milk's role in the neonatal gut microbiome, prebiotics, probiotics, postbiotics, and synbiotics, as well as the airway or respiratory microbiome, and the main role of the neonatal microbiome. We have also discussed neonatal mycobiome and neonatal virome, as well as the research done on the neonatal microbiome.

Effect of hyperbaric oxygen therapy and Tomatis sound therapy in children with autism spectrum disorder.

Many therapeutic and dietary regimens have been studied for children with autism spectrum disorder (ASD) in the last three decades. We aimed to evaluate the efficacy of hyperbaric oxygen therapy (HBOT) and Tomatis sound therapy (TST) in an Egyptian cohort of children with ASD. This study was a prospective, open label, randomized interventional clinical trial. One hundred forty-six children with ASD with no previous rehabilitation therapy were enrolled in our study. Patients were randomly divided into four groups: the first group received hyperbaric oxygen therapy, the second group received Tomatis sound therapy, the third group received a combination of both modalities, and the fourth group, the control group, received no intervention. We found that the combination of Tomatis sound therapy with hyperbaric oxygen therapy had a superior effect in improving autism symptoms than each intervention alone (CARS after therapy 35.04 ± 13.38 versus 49.34 ± 17.54 before the intervention, p < 0.001). The combination of both modalities may be helpful for children with ASD. The most distinctive evidence that supports the use of combination therapy for ASD is still controversial; however, our study provides some evidence of the benefit of combination therapy for children with ASD. Future studies should use a more sophisticated research design and begin by finding a consistent baseline measure that can be used to evaluate the effects of these therapies for ASD.
