Influence of Auditory Integrative Training on Casein Kinase 2 and Its Impact on Behavioral and Social Interaction in Children with Autism Spectrum Disorder.

Considerable disturbances in post-translational protein phosphorylation have recently been discovered in multiple neurological disorders. Casein kinase-2 (CK2) is a tetrameric Ser/Thr protein kinase that phosphorylates a large number of substrates and contributes in several cellular physiological and pathological processes. CK2 is highly expressed in the mammalian brain and catalyzes the phosphorylation of a large number of substrates that are crucial in neuronal or glial homeostasis and inflammatory signaling processes across synapses. In this study, we investigated the impact of auditory integration therapy (AIT) for the treatment of sensory processing abnormalities in autism on plasma CK2 levels. A total of 25 ASD children, aged between 5 and 12 years, were enrolled and participated in the present research study. AIT was performed for two weeks, for a period of 30 min, twice a day, with a 3 h interval between sessions. Before and after AIT, the Childhood Autism Rating Scale (CARS), Social Responsiveness Scale (SRS), and Short Sensory Profile (SSP) scores were calculated, and plasma CK2 levels were assayed using an ELISA test. The CARS and SRS indices of autism severity improved as a result of AIT, which could be related to the decreased level of plasma CK2. However, the mean value of the SSP scores was not significantly increased after AIT. The relationship between CK2 downregulation and glutamate excitotoxicity, neuro-inflammation, and leaky gut, as etiological mechanisms in ASD, was proposed and discussed. Further research, conducted on a larger scale and with a longer study duration, are required to assess whether the cognitive improvement in ASD children after AIT is related to the downregulation of CK2.

Public Awareness of the Association between Periodontal Disease and Systemic Disease.

Periodontal disease is associated with other non-communicable diseases including diabetes mellitus, coronary heart disease and atherosclerosis, hypertension, and respiratory tract infections. This association merits careful study of the general population's awareness level in order to leverage the current state of science to improve general health and quality of life. This study included 502 residents of Saudi Arabia who received computer-assisted interviews to fill up the survey. Results indicated a low level of awareness among the study population regarding the association of periodontal disease to diabetes mellitus, coronary heart disease and atherosclerosis, hypertension, and respiratory tract infections. A higher level of awareness was noticed with individuals with periodontal disease, themselves or a member of their family having a systemic disease, and who have a specialized person or scientific article as their source of information. This observed low level of awareness deserves the attention of public health authorities to prioritize programs that increase the awareness, improve health, and reduce burden of systemic diseases of high prevalence, morbidity, and mortality.
