Background: The use of digital media (DM) is increasing among school-children, which can affect their sleep habits. The primary objective of this study was to evaluate the association of DM use with sleep habits in school-children. Methods: It was a cross-sectional study of healthy school children. Sleep habits and DM use were assessed using the Children's Sleep Habits Questionnaire (CSHQ) and SCREENS-Q, respectively. The Pearson correlation coefficient was used to establish the correlation between the two variables. Logistic regression analysis was performed to quantify the extent of association between variables. A p-value

Background: SARS-CoV-2 infection in children frequently leads to only asymptomatic and mild infections. It has been suggested that frequent infections due to low-pathogenicity coronaviruses in children, impart immunity against SARS-CoV-2 in this age group. Methods: From a prospective birth cohort study prior to the pandemic, we identified children with proven low-pathogenicity coronavirus infections. Convalescent sera from these children were tested for antibodies against respective seasonal coronaviruses (OC43, NL63, and 229E) and SARS-CoV-2 by immunofluorescence and virus microneutralization assay respectively. Results: Forty-two children with proven seasonal coronavirus infection were included. Convalescent sera from these samples demonstrated antibodies against the respective seasonal coronaviruses. Of these, 40 serum samples showed no significant neutralization of SARS-CoV-2, while 2 samples showed inconclusive results. Conclusion: These findings suggest that the antibodies generated in low-pathogenicity coronavirus infections offer no protection from SARS-CoV-2 infection in young children.

Introduction: Calcium is vital for the functioning of the inner ear hair cells as well as for the neurotransmitter release that triggers the generation of a nerve impulse. A reduction in calcium level could therefore impair the peripheric vestibular functioning. However, the outcome of balance assessment has rarely been explored in cases with osteopenia and osteoporosis, the medical conditions associated with reduction in calcium levels. Objective: The present study aimed to investigate the impact of osteopenia and osteoporosis on the outcomes of behavioural and objective vestibular assessment tests. Methods: The study included 12 individuals each in the healthy control group and osteopenia group, and 11 individuals were included in the osteoporosis group. The groups were divided based on the findings of bone mineral density. All the participants underwent behavioural tests (Fukuda stepping, tandem gait and subjective visual vertical) and objective assessment using cervical and ocular vestibular evoked myogenic potentials. Results: A significantly higher proportion of the individuals in the two clinical groups’ demonstrated abnormal results on the behavioural balance assessment tests (p

Auditory evoked potentials serve as an objective mode for assessment to check the functioning of the auditory system and neuroplasticity. Literature has reported enhanced electrophysiological responses in musicians, which shows neuroplasticity in musicians. Various databases including PubMed, Google, Google Scholar and Medline were searched for references related to auditory evoked potentials in musicians from 1994 till date. Different auditory evoked potentials in musicians have been summarized in the present article. The findings of various studies may support as evidences for music-induced neuroplasticity which can be used for the treatment of various clinical disorders. The search results showed enhanced auditory evoked potentials in musicians compared to non-musicians from brainstem to cortical levels. Also, the present review showed enhanced attentive and pre-attentive skills in musicians compared to non-musicians.
