An Assessment of Smartphone Use on Brainstem Auditory Evoked Potentials in Healthy Young Adults in North India Short Title: Assessing BAEP Changes in Young Smartphone Users
(SAGE Publications Inc., 2025) Ayushi Seth; Samir Kumar Singh; Anita Gupta; Hanjabam Barun Sharma
Background: A smartphone is an essential part of our daily existence. Smartphones are used by about 5.26 billion people. Purpose: The purpose of this study was to determine how the duration of smartphone use influenced brainstem auditory evoked potentials (BAEPs). Methods: BAEPs were measured using BERAGRAPH in 41 young healthy persons in an observational cross-sectional study. Results: When daily smartphone calling time is 60 minutes, there is a statistically insignificant difference in smartphone usage length (5 years and >5 years) between the two groups among BAEPs. Conclusion: Despite the P-value being insignificant, there is a positive relationship between smartphone use in years and absolute wave latencies and interpeak latencies of brainstem evoked potentials. © The Author(s) 2025.

Background: Hypertension (HTN) has a genetic predisposition and it also impairs microcirculation, thereby, affecting the well vascularized structures like the brainstem and causing changes in Brainstem Auditory Evoked Potentials (BAEPs). Purpose: To find out the usefulness of BAEPs as a screening tool in apparently healthy individuals with a family history of HTN. Methods: One hundred and ten volunteers, aged 17 to 23 years, were enrolled in the study as participants with proper consent. After excluding the subjects with existing diseases or co-morbidities (e.g. diabetes, HTN, schizophrenia, neuropathy, etc.), those on ototoxic or neurotoxic drugs, a preliminary physical examination was performed, following which BAEPs were recorded with a proper device. Statistical analysis is done with SPSS 2016 software using the chi-square test. Results: A consistent distortion in the inter-peak latency of III-V waves is noted when a family history of HTN is present in either parent or maternal grandparents. Other statistically significant findings are present in V/I% (HTN in mother), wave I (HTN in paternal grandfather), wave III (HTN in maternal grandfather), and inter-peak latency I-V (HTN in maternal grandmother). Conclusion: BAEP may be used as a screening tool in individuals with a family history of HTN with supportive evidence from further studies in the near future. © The Author(s) 2023.

(SAGE Publications Inc., 2025) Samir Kumar Singh; Poonam Jyoti Rana; Anita Gupta; Dibyodyuti Samaddar; Hanjabam Barun Sharma
BackgroundWith technological advancement and economic competitiveness there is an exponential rise in the number of shift workers. Worldwide, healthcare workers constitute the single largest proportion of workers who work on shift duty in order to provide round-the-clock healthcare services to patients. Various studies have demonstrated an association between circadian cycle disturbance due to shift work and adverse health impacts.PurposeThe purpose of the study was to investigate the impact of night shift work on the brainstem-evoked auditory potentials in nursing interns who had been assigned to their first night shift after working day shifts.MethodsA longitudinal, self-case-control study was designed with a sample of 67 nursing interns. Brainstem evoked response audiometry (BERA) had been done after completion of their first posting in Day-shift and then after completion of Night-shift. The paired t-test was used for data analysis.ResultsThe findings of the study showed significant changes in latencies of wave II (p < .0001), wave IV (p < .0001), wave V (p = .012 & .30), interpeak latency III-V (p = .009 & .003) and V/I ratio (p < .0001) for both ears.ConclusionsBERA is an objective non-invasive test to evaluate hearing ability by measuring increased latency and interaural latency difference. After night shift, there were significant changes in auditory acuity which was highly suggestive of delayed transmission in auditory pathway. Hearing impairment has a cascading effect on cognition which may affect night-shift workers’ daily activities and may lead to medical error and risk to patient safety. © The Author(s) 2024.

Gender Variations in Brainstem Auditory Evoked Potentials in Emerging Adults of Northern India
(SAGE Publications Inc., 2025) Anita Gupta; Samir Kumar Singh; Jai Singh Yadav; Anandita Chakravartty; Hanjabam Barun Sharma
Background: Brainstem auditory evoked potentials (BAEPs) aid in the diagnosis of probable neurologic disorders of the VIIIth cranial nerve, the associated auditory pathways, and an estimation of hearing sensitivity, for those who are unable to reliably provide information through behavioural hearing evaluations. BAEPs exhibit variabilities due to numerous pathologic and non-pathologic factors. One of the factors that may have a significant impact on typical BAEPs is gender. Although there are numerous studies documenting gender as an influencing factor on auditory evoked potentials in older subjects, there are few comparable studies among subjects who are just entering adulthood. Objective: The current study aimed to understand the pattern of gender-based differences in BAEPs among emerging adults of Northern India. Methods: The present study was conducted on 120 normal subjects (70 females, 50 males) who were relatives (second degree) of the patients belonging to Northern India aged between 19 and 25 years old, at the Institute of Medical Sciences. Absolute latencies I, III, V and Inter-peak latencies I–III, I–V, III–V were measured separately for both ears. Statistical analysis was done by using the independent t-test and Mann-Whitney U test based on normality through SPSS version 20.0. Results: Results revealed a statistically significant difference in absolute latency of Wave I and inter-peak latency (IPL) of I–III, I–V in the right ear and in the left ear. Wave III and IPL III–V were found to be significant. Females showed shorter absolute latencies and IPLs as compared to males. Conclusion: Significant alterations in BAEPs provide evidence for the potential contribution of gender as an influencing factor in emerging adulthood. © The Author(s) 2025.

Liver Function Markers Response to Different Exercise Intensities in Athletes: A Single Bout Perspective
(Defence Scientific Information and Documentation Centre, 2024) Jagdeep Singh; Pradeep Singh Chahar; Samir Kumar Singh; Surendra Pratap Mishra; Anshul Meena; Ravi Kumar
Exercise provides considerable health advantages through promoting proper body system functioning, healthy growth and development, and quality of life. The present study investigated the effect of single bout High-Intensity Exercise (HIE) compared to Low-Intensity Exercise (LIE) on liver function markers in athletes. This cross-sectional study was carried out in the Department of Physical Education, Banaras Hindu University, Varanasi (UP). A total of 20 healthy male athletes with age range from 22 to 26 years were randomly selected and underwent 5 minutes of HIE and LIE separated by one week. Blood samples for selected liver function markers were taken pre-exercise, immediately, 10 and 20 minutes post-HIE and LIE, respectively. A repeated measures ANOVA with greenhouse-geisser correction found a significant difference between high and low intensity exercises for SGOT (F=5.881; p<0.05) and SBT (F=7.154; p<0.05) values, while statistically insignificant in the case of SGPT (F=1.572; p>0.05). In high intensity exercise there was statistically significant difference for SGOT (F=7.564; p<0.05) value between different time points. Post hoc analysis with a bonferroni correction showed that SGOT value was significantly increased immediately after the HIE, reducing 10 minutes after the exercise and closely returned to baseline level after 20 minutes of exercise, whereas LIE showed no significant changes. Exercise intensity is important as it triggers liver pathology by asymptomatic modifying liver function markers. These findings can be used to develop and administer exercise training plans for athletes. © 2024, DESIDOC.
