Item Comparative Study of Energy Utilization and Green House Gas Emission by Hybrid Rice Grown under Two Different Cultivation Systems in Red Lateritic Zone of West Bengal(SCIENCEDOMAIN international, 2019-06) Ghosh, A.; Das, S.; Reja, M.; Maity, SA field experiment was carried out at Agriculture Farm, Palli Siksha Bhavana, Visva-Bharati, Sriniketan, West Bengal, India during kharif season of 2015 to compare rice cultivation in conventional transplanting (CT) and system of rice intensification (SRI) in terms of energy use, energy input output relationship and green house gas emission. Results showed that regardless of cultivars, conventional transplanting consumed 62.39% higher energy over SRI. Maximum energy input was associated with non renewable and indirect sources. Higher dose of nitrogenous fertilizer had contributed to 32.35% and 26.26% to the total input energy in CT and SRI respectively. Energy use efficiency (13.22), energy productivity (6.94 kg MJ-1), energy profitability (12.22) and energy intensity (4.60 MJ Rs-1) of hybrid rice varieties were noted higher in SRI. Maximum green house gas emission from rice field was also attributed to fertilizer nitrogen followed by diesel in both the system. Total green house gas emission in CT was estimated to 834.85 (kg CO2ha-1) i.e. 1.8 times of SRI. Engirdling different energy indices, total input energy and green house gas emission, the system of rice intensification was emerged as the most energy efficient and sustainable rice production system in resource stricken areas (Red Lateritic Zone).Item The correlation of cardiovascular risk factors and angiographic findings with serum vitamin D levels in patients undergoing coronary angiography(Medip Academy, 2018-01) Tripathy, S. K.; Dhal, N.; Pattnaik, S.; Routray, S. N.; Das, S.; Mishra, S. K.; Panigrahi, M.; Mohanty, B.; Behera, M. R.Background: Studies regarding correlation of various conventional risks factors for Coronary Artery Disease (CAD) are many. Keeping in mind the scarcity of studies regarding Vit-D Deficiency (VDD), a new risk factor in CAD, present study was conducted to correlate Vit-D level with conventional risk factors and Coronary Angiography (CAG).Methods: Hundred adult patients admitted to Medicine and Cardiology undergoing CAG with suspected or established CAD were kept in study. Patients having renal, hepatic, parathyroid disease, osteomalacia and patients taking drugs interfering with Vitamin D (Vit-D) metabolism were excluded. After detailed history and thorough clinical examination, routine investigations and 25-(OH) D level was estimated. Subsequently patients underwent CAG. Statistical analysis by Mann Whitey test and Chi-square Test was done and inference was drawn.Results: 100 patients in different age groups had hypertension (HTN) in 53, diabetics mellitus (DM) 39, dyslipidemia 62, smokers 38 and family history of CAD 19. CAG showed normal coronaries in 4, Single Vessel Disease (SVD) in 30, double vessel diseases (DVD) 43 and triple vessel disease (TVD) 22. Vit-D level <20ng/ml i.e. Vit-D deficiency (VDD) in 68, 20-30ng/ml i.e. Vit-D insufficiency (VDI) in 22 and >30ng/ml (normal) in 10. VDD was profound in 51-60 and 61-70 years age groups. Statistical correlation of VDD was not significant with conventional risk factors, but statistically significant correlation of VDD was observed with dyslipidemia and CAG findings in our study.Conclusions: Like earlier studies we observed significant correlation of Vit-D levels with CAD. Though dyslipidemia was significantly correlated with VDD, correlation of other conventional risk factors like age, sex, HTN, DM, smoking and family history was not found. We conclude from this study presence of significant association of VDD with severe CAD. DVD and TVD by CAG were common with low Vit-D levels.Item An observational study on utilization of blood and blood components in a tertiary care hospital of Kolkata, West Bengal(Mrs Dipika Charan of MedScience (India) Publications, 2022-08) Manna, N; Bhattacharya, P; Mukherjee, R; Das, S.Background: Blood is essential for human survival though it is a scarce and precious resource. Blood Transfusions also have some risks, like immunomodulation in the recipients, transmission of infectious agents, and may lead to serious adverse reaction. Hence, it is necessary to make an efficient use of blood and blood products. Aims and Objectives: With this background, the present study was carried out at the blood bank of Medical College and Hospital, a tertiary care hospital of West Bengal, India to evaluate the utilization pattern of blood and blood components. Materials and Methods: Facility based, observational, descriptive, and cross-sectional epidemiological study was conducted on the basis of secondary data collected from records of blood bank, medical college, Kolkata, regarding blood and blood component transfusion pattern of patients who were admitted in medical college and hospital and received blood and blood components from blood bank medical college, Kolkata during period from September 1, 2021, to September 15, 2021. Results: Total number of transfusion recipients during the study period was 1339. Total 2621 no of blood and blood components were issued. About 66.84% (895) of all recipients were transfused with single unit of blood or blood component. Packed red blood cells were the maximum utilized blood component. The most common diagnosis for patients requiring blood and blood components was anemia. Conclusion: A large proportion of patients were transfused with single unit of blood or blood component, which might not be beneficial. Training, regular meeting with clinicians and periodic assessment of blood usage are recommended to prevent inappropriate transfusion.Item Phenotypic stability and homeostasis in Assam rice landraces at varying nitrogen regimes(Triveni Enterprises, 2019-11) Das, S.; Sarma, D.; Das, S.S.Aim: The present study was designed to identify stable rice (Oryza sativa L.) genotypes for nitrogen use efficiency (NUE), yield and its component traits and also to identify component traits associated with yield stability. Methodology: Twenty-one landraces along with five high yielding varieties (HYVs) of rice were evaluated at three nitrogen levels (0, 40 and 60 kg N ha-1) for two years (2014 and 2015). Eberhart and Russel’s (1966) stability analysis were employed to assess the genotype × environment (GE) interaction and the stability of the genotypes across six environments. To study homeostasis, simple correlation analysis among ten different traits was done based on stability parameters. Results: The present study revealed that environments created by graded nitrogen levels were fruitful for inducing environmental variations. The highly significant linear environmental variances were found for all ten traits. Linear GE interaction was significant for all the traits, except harvest index, grain nitrogen and nitrogen harvest index. The stability analysis identified four genotypes viz., Kolabor, Aki Bora, Rongdoi and Luha Sali with average stability whereas Betguti Sali was found to be stable below average. Correlation analysis based on stability parameters revealed the existence of homeostasis. Interpretation: Present study revealed that genotypes namely Kolabor, Aki Bora, Rongdoi and Luha Sali are suitable to grow under both nitrogen limiting and nitrogen non-limiting environments whereas Betguti Sali was suitable for nitrogen non-limiting environments. Correlation analysis, based on stability parameters, revealed that yield stability was due to the plasticity of some other component traits under study.Item Study of clinical profile of organophosphorus poisoning with special reference to electrocardiographic changes and electrolyte derangement(Medip Academy, 2018-01) Tripathy, S. K.; Rout, P. K.; Debta, N.; Das, S.; Panigrahi, M.; Mishra, S. K.; Suna, S. P.; Behera, M. R.Background: Organophosphorus Compounds (OPC) are main cause of accidental and suicidal poisoning in agrarian countries like India. Aim was to study the clinical profile of OPC-Poisoning and correlate it with the electrocardiographic (ECG) changes and electrolyte abnormalities.Methods: Hundred consecutive cases admitted to Medicine Department underwent clinical examination, ECG, electrolytes, Acetyl Choline Esterase (AChE) estimation from time to time and Paradeniya Organophosphorus Poisoning (POP) score at the time of admission. All these parameter with duration of hospital stay and outcome were statistically analysed using X2 test, Fisher exact test, and inference was drawn.Results: In hundred OPC-Poisoning patients [Male (n=48), Female (n=52), M: F ratio 0.92:1] with mean age of 37.78�.95 years, commonest poison was cholropyrifos+cypermethrin and was mostly suicidal (96%). Common symptoms were sweating (48%), salivation, blurring of vision, breathlessness and signs were smell of poison (90%), tachypnea, altered sensorium, miosis and fasciculation. POP scoring found 41% of patients in mild, 26% in moderate and 33% in sever grade of poisoning. Hospital stay ranged from 4-18 days. Complications were pulmonary Edema (PE) in 28%, Respiratory Failure (RF) 18%, Aspiration Pneumonia (AP) 15% and Intermediate Syndrome (IS) 4%. 10 died out of 42 patients who had complications and the cause of death was RF in 4, Ventricular Fibrillation (VF) 2 and IS in 2. ECG finding showed sinus tachycardia (31%), prolonged corrected QT (QTc) interval (28%), sinus bradycardia (25%), ST-T changes (17%) and Premature Ventricular Contraction (PVC) in 4% which degenerated to VF in 2%. 24 patients were Hypokalemic from which 16 developed complications.Conclusions: Similar to earlier studies we observed poisoning which was suicidal. QTc prolongation and Hypokalemia are associated with high morbidity and mortality in OPC-Poisoning.Item A study on menstrual abnormalities among undergraduate students of medical college, Kolkata(Mrs Dipika Charan of MedScience (India) Publications, 2023-06) Manna, N; Jainendran, AS; Mondal, S; Das, S.Background: Menstruation is a taboo subject among adolescents girl; lack of knowledge regarding the menstruation, menstrual hygiene, and menstrual abnormalities has significant negative influence on young women. Most of the time menstrual abnormalities were not reported timely resulting in their late diagnosis as well as intervention, burdening adolescents and young adult women physically and mentally. Aims and Objectives: This study aimed to identify the menstrual patterns, abnormalities, effects of these abnormalities on the student population in form of social withdrawal, sickness absenteeism, and degrading academic performances. Materials and Methods: A cross-sectional study on menstrual abnormalities among 187 undergraduate students of Medical College Kolkata was conducted to illuminate menstrual problems and its effects on their regular activities. By systematic random sampling technique participants were selected. Questions were related to menstruation, variations in menstrual patterns, dysmenorrhea and its severity, premenstrual symptom, family and medical history in relation to menstrual abnormalities, social withdrawal, monthly sickness absenteeism and degrading of academic performances. Results: The mean age of subjects at menarche was 13.19 ± 0.931 years. Of all the abnormalities, dysmenorrhea was the highest with 84% of prevalence, followed by pre-menstrual symptom with prevalence of 68.4%. Social withdrawal (17.8%), college absenteeism (5.7%), and degrading of academic performance (8.2%) were reported among the students. Conclusion: Menstrual abnormalities must be promptly diagnosed and treated, and students must get counseling addressing these issues if they are to improve their health and quality of life and reduce their chances of developing further illnesses.Item A study on mental distress among the undergraduate students of medical college, Kolkata(Mrs Dipika Charan of MedScience (India) Publications, 2023-05) Manna, N; Mondal, S; Jainendran, AS; Das, S.Background: Medical students are reported to have high levels of mental distress that includes problems such as anxiety, depression, and stress due to the highly competitive curriculum. In the post-pandemic era with a renewed perspective toward health system and popularization of online classes, current batch of students are exposed to diverse sources of mental distress. Aims and Objectives: Objectives of this study were to find out the socio-demographic and behavioral characteristics, family background and academic profile of the study participants, and to estimate the proportion of different varieties of mental distress among them, and to examine relationship of mental distress with sociodemographic, behavioral and academic profile. Materials and Methods: A cross-sectional observational study was performed on 649 undergraduate students by census method using depression anxiety stress scale-21 items. Results: The study participants are predominantly Hindu, urban, unmarried, hostelites, males from nuclear families and belonging to upper socioeconomic class according to Modified B.G Prasad Socioeconomic Status Scale (January 2022). The proportion of depression, anxiety, and stress among study participants was found to be 49.61%, 58.86%, and 33.13%, respectively. Proportion of mental distress was significantly higher in the age group of 21–24 years. Those who preferred to study more at night were more anxious and stressed. Stress was higher in students with addiction to gadgets too. Participants hailing from rural areas, hostelites, and paying guests were relatively more depressed. Conclusion: There is urgent need for emotional support and provision of personalized counseling for the MBBS students as unchecked mental distress can turn into severe psychological morbidity.
