Item Comparison of clinical utility of Cancer Ratio, CEA, Malignant Cytology in diagnosis of suspected malignant pleural effusion(Department of Community Medicine, Institute of Medical Sciences, Banaras Hindu University, Varanasi- 221005, India., 2022-12) Singh, M.; Mishra, J. K.; Sharma, M.; Lobiyal, S.; Dash, S. S.Introduction: Pleural effusion is one of the manifestation of a malignant disease which may be malignant pleural effusion with demonstrable malignant cells in the fluid or para-malignant pleural effusion which is reactive response or due obstruction of lymphatic drainage rather than invasion of pleural cavity. Various modalities are there to investigate this condition including routine microscopy, cytology, biopsy etc. Objective: To understand and compare the utility of cancer ratio, tumor markers, malignant cytology in cases of suspected malignant pleural effusion. Material and Methods: This Case Control Cross sectional study was conducted among patients attending respiratory OPD at Sir Sunder Lal Hospital, BHU, Varanasi, diagnosed with malignant pleural effusion and non-malignant pleural effusion. Results: Significant association was found between Cancer Ratio-Carcinoembryonic Antigen, CEA (p = 0.0069), CEA-Cytology (p = <0.01801)Item DNA damage in spleen as a indicator of genotoxicity in Channa punctatus exposed to 4-nonylphenol(Triveni Enterprises, 2020-01) Sharma, M.; Chadha, P.; Sharma, P.Aim: The present study was performed to evaluate the genotoxic effect of 4-nonylphenol after acute and subchronic exposure in spleen tissue of Channa punctatus, recovery in DNA damage was also ascertained after 30 days of cessation of exposure.Methodology: Tail length (TL), tail intensity (TI), tail moment (TM), Olive tail moment (OTM) was used as biological indicators of DNA damage. The fish were exposed to different sublethal concentrations of 4-NP for 96 hrs (acute exposure) and for 90 days (sub chronic exposure). Results: Exposed groups showed significantly higher DNA damage in both acute and sub chronic exposure as compared to control groups. In the case of acute exposure, the highest damage was observed at 24 hr of exposure followed by a decline in the value of all the parameters, while in the later hours of exposure these value further increased. On the other hand, in the case of sub-chronic exposure, the highest damage was observed after treatment with 0.10 mg l-1 concentration of 4-NP at 90 days of exposure. Recovery experiment showed a decrease in the values of all the parameter’s studied, however, a significant decrease was observed only at the highest concentration. Interpretation: The results conclude the DNA damaging potential of 4-nonylphenol and highlighted the usage of spleen tissue for genotoxicity testingItem Electrocardiogram abnormalities detected during a routine medical examination of healthy members of the armed forces: An observational study(Department of Community Medicine, Institute of Medical Sciences, Banaras Hindu University, Varanasi- 221005, India., 2023-03) Sharma, M.; Sengupta, S.; Maribashetti, K.; Karanth, J. B.Background and objective: Only few studies addressed ECG findings in healthy members of the Indian armed forces or the general population of India. The study was conducted to assess the prevalence of abnormal electrocardiogram (ECG) detected during a routine medical examination of healthy members of the Indian armed forces. Method: The ECG of all the healthy members performed during a routine medical examination was initially reported by physicians at various armed forces service hospitals in the Eastern Command (EC) and later perused by the cardiologist at Command Hospital Eastern Command (CHEC). Individuals with abnormal ECG underwent relevant cardiac evaluation at CHEC to determine the underlying pathology. Results: A total of 1,045 members of the Indian armed forces were included in the study and were categorised as follows: 244 in Group-1 (aged < 25years), 478 in Group-2 (aged between 25 to 40 years) and 323 in Group-3 (aged > 40years). Abnormal ECG was found in 108 (10.3%) individuals. Left axis deviation was the most common abnormality detected in 18 (1.2%) individuals, followed by incomplete RBBB and T wave inversion which were each found in 15 subjects (1.43% of all individuals and 13.9% of the subjects with abnormal ECG). The prevalence of ECG abnormalities detected in our study was similar to that reported in previous studies. Only five (0.47%) of the 108 individuals with abnormal ECG were found to have underlying cardiovascular disease. Conclusion: Morphological ECG abnormalities were common in the subjects but did not vary significantly from the general population, and only a minority had underlying pathology. While most of the abnormalities may only represent normal variations and their occurrence in healthy individuals during routine health check-ups should not be alarming. Evaluation of structural heart disease should be done for ECG abnormalities with prognostic significance that has been well-characterised.Item Impact of COVID-19-related lockdown on metabolic syndrome variables in healthcare workers with pre-existing metabolic syndrome: A prospective study(Mrs Dipika Charan of MedScience (India) Publications, 2023-06) Singh, O; Gupta, M; Sharma, M.Background: An extraordinary impact on health-care personnel has been caused by the coronavirus disease-2019 (COVID-19) pandemic, a health-care crisis. Aims and Objectives: Our aim was to assess the effects of a changing lifestyle on anthropometric measurements, blood glucose levels, atherogenic lipid profiles, and blood pressure over the course of a year in Indian healthcare workers (HCWs). Materials and Methods: A prospective study was carried out on 40 HCWs including 23 male and 17 females between the age of 22 and 59 years. The study was conducted in the Department of Physiology and the Department of Biochemistry, Government Medical College, Kathua, UT of Jammu and Kashmir. Informed written consent was obtained from the subjects and ethical clearance was obtained from the Institutional Ethics Committee. Height, weight, waist circumference, and systolic and diastolic blood pressure were measured using standard methods. Body mass index was calculated as weight in kilograms divided by the square of height in meters. Results: The present study found statistically significant increase in systolic blood pressure and statistically significant decrease in mean HDL-cholesterol before and after COVID-19 pandemic in HCWs. Conclusion: The onset of metabolic syndrome and its potential effects could be stopped by early use of preventative interventions in the changed parameters.Item Landuse impact on soil physical variability and erodibility in North Western subtropics of India(Triveni Enterprises, 2019-07) Abrol, V.; Sharma, R.K.; Sharma, V.; Sharma, P.; Sharma, K.R.; Kumar, A.; Sharma, M.Aim: The study was conducted to determine the impact of landuse on soil physical properties and erodibility. Methodology: Representative soil samples were collected from surface and sub-surface soil depths. Soil physical properties and erodibility indices viz suspension percentage, dispersion ratio, clay/moisture equivalent ratio, erosion ratio, percolation ratio, clay ratio, erosion index and modified clay ratio were determined using standard procedures. Interrelationship among soil properties and erodibility indices were evaluated using Pearson correlation analysis (at 95% and 99% significance level). Results: Among landuse systems, the clay was highest in forest while least in soils under barren landuse. Lowest bulk density and highest value of maximum water holding capacity was found in forest soils. According to susceptibility to erosion, the landuse systems were found in the following order barren lands > cultivated systems (agriculture and horticulture) > forest lands. The ‘r’ values showed positive and highly significant correlations between sand content and bulk density with suspension percentage (SP), clay ratio (CR), modified clay ratio (MCR), dispersion ratio (DR), percolation ratio (PR), erosion ratio (ER), erosion index (EI) while negative and significant correlations of these erodibility indices were found with clay and porosity. Among the erodibility indices SP, DR, PR, ER and EI were positively and significantly correlated with each other. Interpretation: Physical quality of soil was higher in forest compared to other landuse systems. Erodibility of different landuse systems could be arranged in order barren lands > cultivated systems (agriculture and horticulture) > forests. The study was useful for suggesting remedial measures and landuse planning for futureItem Satisfaction levels of students toward online teaching and assessment in a medical college in North India during COVID-19 related lockdown(Mrs Dipika Charan of MedScience (India) Publications, 2023-01) Arora, R; Moudgil, T; Cheema, HK; Sharma, M.Background: Medical colleges had to adopt online teaching methods after the imposition of worldwide lockdown due to COVID related pandemic. It is important to understand satisfaction levels among medical students regarding online teaching, to improve online teaching methods in future. Aim and Objectives: The present study aimed to evaluate the satisfaction levels among medical students with regard to online teaching and assessment program and factors associated with low satisfaction levels. Materials and Methods: An observational cross-sectional survey was conducted on 600 MBBS students. Various online teaching methods were implemented April 2020 onward. This survey was sent to the students in July 2020. Satisfaction levels toward various online teaching and assessments were evaluated using a five point Likert scale. Results: A total of 446 MBBS students responded to our survey. We found 1st year of MBBS curriculum (adjusted odds ratio [AOR] = 2.55, P < 0.05), teachers’ inability to explain theory concepts (AOR = 2.47, P < 0.01), teachers not keeping the class interactive (AOR = 1.81, P < 0.01), student unable to hear the teacher adequately (AOR = 1.77, P < 0.01), student being inattentive in class (AOR = 2.06, P < 0.01), and non-availability of high speed internet connectivity (AOR = 1.85, P < 0.001) to be significantly associated with students not being overall satisfied with online teaching. Conclusion: Online platforms proved to be relevant for teaching theory but usefulness for clinical or practical education was not found to be adequate.
