Knowledge, Attitude and Practices Regarding Electronic Waste (e-waste) Management Among Users of Electronic Equipments Living in Lucknow City

Background: Contemporary society has led to the increasing use of electronic equipment that is very much responsible for the burden of electronic waste (e-waste). E-waste contains very hazardous substance that harms health and environmental conditions. There is no delicate mechanism for the management of e-waste in Lucknow city, Uttar Pradesh. This study assessed knowledge, practice, and awareness of e-waste management among residents of this city. Material and methods: The study was conducted amongst users of electronic equipment living in the Lucknow City of Uttar Pradesh. The study was a cross-sectional descriptive study. Multi-stage random sampling was done for the selection of participants for the study. A predesigned and pretested questionnaire was administered in a single setting for all phases. The total optimum sample size is 700 individuals who participated in the study. Data were entered in MS Excel 2016 and descriptive statistics such as frequencies and percentages were calculated, applying the chi-square test for association using R-4.2.1 Statistical software. Aim and objectives: To assess the knowledge, attitude and practices regarding the management of electronic waste among users of electronic equipment residing in Lucknow city. Results: Only 37% of users are aware that e-waste adversely affects health. Only 34.3% of users knew that e-waste should be given to the seller or manufacturer for recycling while rest told that it should be stored at home, sold to a scrap dealer, or disposed with normal waste. 87.3% users are not aware about e-waste govt guidelines. In the current study electronic and print media like television, radio and news paper were not found to be source of information for e-waste disposal. Conclusion: Education regarding the ill effects of e-waste is essential for people and awareness of proper disposal of e-waste is the need of the hour. Electronic and print media as well as companies producing electronic equipment should play a significant role to awaken the respondent about the disposal of e-waste

Experience of laparoscopic cholecystectomy in patients presenting with acute cholecystitis at different duration

Background: Acute inflammation of a gall bladder that contains stones is acute calculous cholecystitis, laparoscopic cholecystectomy is now the gold standard treatment for patients with gall stone disease. laparoscopic cholecystectomy for acute cholecystitis was initially considered technically challenging and potentially risky for the patient. Aim was to evaluate results of laparoscopic cholecystectomy in patients presenting with acute cholecystitis at different duration in a tertiary centre in eastern India. Methods: Comparative study of 71 cases of acute cholecystitis who presented at different days and were treated by laparoscopic cholecystectomy. Outcome was compared. Results: The incidence of conversion to open was 12.6%. Day of presentation 5 to 7 had the maximum 21% risk of conversion. Major intraoperative complications included 4 cases of common bile duct injury, 4 cases of vascular injury and 3 cases of bowel injury out of which vascular injury and one case of bowel injury was managed laparoscopically. 9 cases converted to open surgery. patient with DOP 1, 2 and 3 had an average hospital stays of 3 days. It was 5 for those with DOP 4 and 7 days for patients with DOP 5 to 7. Conclusions: The study supports laparoscopic cholecystectomy in acute cholecystitis specially in patients presenting within 72 hours of onset of pain. Laparoscopic cholecystectomy can be attempted in patients who present at DOP 4 and DOP 5 to7 after explaining them the risk and benefit of the procedure to the patient. Conversion to open surgery should not be stigmatized.

Quality of life of people living with HIV/AIDS before and after receiving antiretroviral therapy

Background- HIV/AIDS is a chronic illness. Besides having serious morbidities, opportunistic infections, it also adversely affects quality of life of People Living with HIV/AIDS (QOL- PLHIV). Early and prompt initiation of antiretroviral therapy (ART) might improve quality of life of PLHIV in various domains like psychological, physical, environment level of independence, social relationship and spirituality/religion/personal beliefs. Material and methods- The study was conducted at a medical institute of North India. Patients attending ART centre of the institute for the treatment of HIV/AIDS were interviewed on WHOQOL-HIV questionnaire. Aim and objectives- To assess and compare quality of life of people living with HIV/AIDS at initiation and after 6 months of receiving antiretroviral therapy. Result- QOL-PLHIV was improved in various domains when assessed after six months of receiving ART. For physical domain mean score increased from 12.83 to 13.85, for psychological domain from 12.54 to 14.31, for level of independence from 12.95 to 13.21, for social relationship from 12.46 to 14.15, for environment domain from 11.98 to 13.15 and for spirituality/religion/personal belief mean score increased from 11.41 to 11.96. Respective standard deviation was decreased when compared from before initiation of ART to six months after receiving ART. Conclusion – Quality of life of people living with HIV/AIDS was improved significantly after receiving ART.

Nutrient Composition, Metabolites and Microbial Counts in Litter Material of Broiler Chicken Fed Condensed Tannins Containing Guava Leaf Meal Supplemented Diets: Reduce Environmental Pollution and Alternate Feedstuffs for Ruminants

Present study was conducted in 240 day-old broiler chicks to assess the effect of condensed tannins (CT) containing guava leaf meal (GLM) supplemented diet on nutrient composition, litter metabolites viz. pH, moisture and ammonia concentration) and microbial counts after completion of feeding trial of 42 days. Chicks were randomly allocated into 4 dietary treatments, with 4 replicates of 15 chicks in each pen in a completely randomized block design (CRD). Chicks were fed basal diets supplemented with GLM @ 1.5, 2.5 and 3.5 percent, in T1, T2 and T3 groups, respectively, while, T0 group fed only basal diet. Litter materials of chicks showed good nutrient profiles and properly sterilized litter material act as alternative feed ingredient for ruminants feed. Supplementation of GLM in the diets of chicks significantly (P<0.05) reduced moisture, pH, NH3 concentration, harmful Eschericia coli and Clostridia spp. counts in the litter materials and reduced environmental pollution. The litter material of GLM supplemented (T1, T2 and T3) chicken showed significantly higher (P<0.05) CP contents as compared to un-supplemented control. It can be concluded that properly sterilized litter material of GLM supplemented chicks act as cheaper alternative feedstuffs for ruminant’s ration and reduce environmental pollution by lowering NH3 concentration, harmful E. coli and Clostridia counts in broiler litter material

Influence of Eugenia jambolana and Psidium guajava Leaf Meal Mixture Supplementation on Carcass Characteristics and Economics of Broiler Chickens

Present study was conducted in 120 day-old unsexed broiler chicks. They were randomly distributed into 4 dietary treatments (T1, T2, T3 and T4) supplemented with leaf meal mixture (LMM) of Eugenia jambolana and Psidium guajava@ 0, 2.5, 5.0 and 7.5 % of diet, respectively of 30 birds per treatment, each having 3 replicates (10 chicks per replicate) in a complete randomized block design (CRD). Significantly (P<0.05) higher mean body weight was observed in T1 as compared to T2, T3 and T4 groups. Carcass yields viz. live weight, de-feathered weight, slaughtered weight and eviscerated weights (in gram and % LWt.) were statistically non significant (P>0.05) with and without LMM supplemented diets. However, weights of spleen and liver were significantly (P<0.000, P<0.026) higher in LMM supplemented groups as compared to un-supplemented control (T1). Dietary supplementation significantly reduced abdominal fat content in T4 compared to T1, whereas, T2 and T3 have an intermediate values between T1 and T4 and increased the net profit, it ranged from ` 30.41 to 34.24 per bird

Effect of Eugenia jambolana and Psidium guajava Leaf Meal Mixture Supplementation on Performance, Biochemical Profile and Histopathological Changes of Broiler Chicks

Present study was undertaken in 120 day-old broiler chicks, randomly distributed into 4 dietary treatments (T1, T2, T3 and T4 supplemented with leaf meal mixture (LMM) of Eugenia jambolana and Psidium guajava @ 0, 2.5, 5.0 and 7.5 % of diet, respectively) each having 3 replicates (10 chicks/ replicate) in a complete randomized block design (CRD). Experimental chicks were fed basal diets (starter and finisher) supplemented with graded levels of LMM. Feed intake, body weight gain and feed conversion ratio (FCR) were recorded at weekly intervals. Two birds from each replicate were slaughtered at the end of feeding trial (42 days). Blood samples were collected and serum separated for biochemical profiles. For histopathological examination, representative tissue samples were collected in 10% neutral buffer formalin and then processed for paraffin embedding employing alcohol as dehydrating agent and xylene as clearing agent. Sections were cut at 4-5µm thickness and stained by routine haematoxylin and eosin method. On histopathological examination of liver, kidney, heart and intestine of T1 and T2 groups showed normal integrity, mild to moderate histopathological changes in T3 group, while, T4 showed drastic histopathological changes. It was concluded that E. jambolana and P. guajava LMM supplementation (2.5% or even 5%) maintained birds performance, minor histopathological changes and producing healthy low cholesterol broiler meat. The LMM incorporation (2.5%) in the diet of broiler chicks may be recommended as socioeconomic, alternative functional feed resource

Morphological and anatomical aberrations induced by waterlogging in sugarcane

Aim: The present investigation was carried out to study root anatomy of sugarcane cultivars (CoLk 94184 and CoJ64) planted under waterlogged condition through Scanning Electron Microscopy (SEM). Methodology: Two sugarcane (Saccharum spp. hybrid) cultivars, CoLk 94184 and CoJ 64 were evaluated for changes in root anatomy in response to waterlogging during 2017-2018. For waterlogging treatment, crop was grown in deep plot which was waterlogged upto a depth of 1 m during active grand growth stage (monsoon season) along with untreated control plot. After three months of waterlogging, the plants were uprooted to study the root morphology and anatomy through SEM. Results: Waterlogged plants showed aerial root formation in both the cultivars but number and mass were higher in CoJ64. Aerenchyma was formed in the cortical region of both control and waterlogging roots but the size was relatively increased in waterlogged. Irregular and damaged surface cells with longer root hairs were observed in waterlogging treatment. Waterlogged roots exhibited cell distortion, loss of uniformity in endodermis and pericycle regions and higher number of metaxylem vessels. Interpretation: The study concluded that waterlogging treatment caused structural anomalies and induced anatomical and surface ultra-structural changes in both the cultivars, but the level of deformation was relatively higher in genotype CoJ 64, indicating sensitivity towards waterlogging as compared to cultivar CoLk 94184.

A study of fasting lipid profile in chronic kidney disease patients

Background: Dyslipidemia is very much common in chronic kidney disease patients and is responsible for cardiovascular disease (CKD) which is most common cause of mortality in them. So, it is necessary to study the lipid profile in CKD patients to prevent morbidity and mortality.Methods: Subjects each of 50 in number are grouped into healthy controls (group-1), CKD patients without hemodialysis (group-2), CKD patients with hemodialysis (group-3). After fasting of 12 hours, lipid profile is assessed in all cases.Results: In this study, there is increase in Total cholesterol (TC), Low Density lipoprotein (LDL), very Low-Density lipoprotein (VLDL) and Triglycerides (TG) and decrease in High Density Lipoprotein (HDL) in all CKD patients compared to healthy controls (p-value for each parameter <0.001). There is increase in TC, TG and VLDL in diabetic CKD patients compare to non-diabetic CKD patients and p-value for each parameter is <0.05. It was found that TG and VLDL increase and HDL decrease in group-3 compare to group-2 is statistically significant (p-value for each <0.05) and no significant variation in TC and LDL in these groups.Conclusions: Present study demonstrated that there is dyslipidemia in CKD patients irrespective of mode of management, but the derangement is much more common and significant in CKD with hemodialysis group and they are at risk of cardiovascular disease. It is better to start lipid lowering drugs which decreases disease progression and dyslipidemia.

Assessment of waterlogging induced physio-biochemical changes in sugarcane varieties and its association with waterlogging tolerance

Aim: The aim of the present investigation was to study the effect of waterlogging on growth and physiological behaviour of sugarcane varieties, and to evaluate these in relation to waterlogging tolerance to identify reliable physiological parameters for screening sugarcane genotypes for waterlogging tolerance.. Methodology: Ten sugarcane varieties including four tolerant and one sensitive were planted under waterlogged and non waterlogged (control) conditions. Waterlogging was imposed for 70 days at the crop age of 120 days, thereafter water was completely drained. Based on relative cane weight (% waterlogged/control), the ranking of varieties was done for waterlogging tolerance. Changes in cane weight, stalk growth rate, internode length, chlorophyll stability index and antioxidant enzyme activity were measured at the end of waterlogging. Leaf samples were analysed for nitrogen, phosphorus and potassium content. Correlation between waterlogging tolerance and different traits was assessed. Results: Based on relative cane weight (% waterlogged/control), CoLk 94184 was found to be the most waterlogging tolerant variety while CoJ 64 the most sensitive. Waterlogging remarkably reduced stalk growth rate and a significant positive correlation was found between waterlogging tolerance and stalk growth rate during waterlogging. The average internode length of sugarcane varieties increased by 11% in waterlogging as compared to control. Tolerant varieties had high chlorophyll stability index than sensitive one showing that tolerant varieties had less chlorosis in waterlogging. Waterlogging caused a significant increase in antioxidant enzyme activity of catalase, peroxidase and superoxide dismutase, however these increase were higher in tolerant varieties. Waterlogging induced severe deficiencies of N, P and K in sugarcane; the leaf N and K concentration were below critical deficiency level. A strong positive correlation was found between leaf K content and waterlogging tolerance. Interpretation: Stalk growth rate, chlorophyll stability index and leaf potassium concentration during waterlogging were identified as efficient physiological traits for screening the sugarcane varieties for waterlogging tolerance.

Role of forensic medicine in administration of justice a critical review.

Two small round opaque shadows of metallic densities opined as that the injury was not a firearm injury but was self inflicted one by the first Medical Board under the Chairmanship of Chief Medical Officer. Opinion of another Medical Board comprising Forensic Medicine expert considered it as a: Clear cut case of firearm wound. Based on two contradictory opinions, Allahabad Court held that the Charge: sheet submitted under sections 323, 504, and 506 IPC, ought to have been submitted under some graver sections too. This paper deals with a critical review of case where two Medical Boards were constituted in the interest of justice. Views of various other relevant judgments of Hon’ble Supreme Court and various High Courts emphasizes the importance of Forensic Medicine in the administration of justice and need for refresher courses and training for medical officers suggested to avoid future recurrences of such nature are discussed in brief.

Effect of change in symptoms, respiratory status, nutritional profile and quality of life on response to treatment for advanced non-small cell lung cancer.

INTRODUCTION: Quality of life (QOL), and pulmonary and nutritional parameters are important outcome measures during treatment of lung cancer; however, the effect of chemotherapy on these factors and their relationship with clinical response is unclear. METHODS: Patients with non-small cell lung cancer (NSCLC) were evaluated for symptom profile, nutritional status (using anthropometry), pulmonary functions by spirometry and six minute walk distance (6 MWD), and QOL using the WHO-QOL Bref 26 questionnaire, before and after chemotherapy. RESULTS: Forty-four patients were studied (mean (SD) age, 55 (10) years, 75% males). The majority (98%) had stage III or IV disease and 72% were current / ex-smokers with median pack-years of 27.0 (range, 0.5-90). Some 61% had a Karnofsky Performance Scale (KPS) 70 or 80. The commonest symptoms were coughing, dyspnea, chest pain, anorexia and fever (79%, 72%, 68%, 57% and 40%, respectively). The mean (SD) 6 MWD was 322.5 (132.6) meters. The mean (SD) percentage forced vital capacity (FVC %), and forced expiratory volume in one second (FEV1 %) were 64.7 (18.8) and 57.8 (19.4), respectively. The mean (SD) QOL scores for the physical, psychological, social, and environmental domains were 52.9 (20.5), 56.1 (17.9), 64.5 (21.8), 57.1 (16.6), respectively. Fourteen patients (32%) responded to chemotherapy. Non-responders had significantly higher baseline occurrence of fever, anorexia, and weight loss, higher pack-years of smoking and poorer KPS compared to responders. Overall, chemotherapy caused significant decline in the frequency of coughing, dyspnea, chest pain, fever, anorexia, weight loss, and improvement in hemoglobin and albumin levels. There was no significant improvement in pulmonary functions, nutritional status, or QOL scores after treatment. CONCLUSIONS: Lung cancer patients have a poor QOL. Although chemotherapy provides significant symptomatic benefit, this does not translate into similar benefit in respiratory and nutritional status or QOL. Patients with constitutional symptoms, higher smoking burden, and poor KPS are less likely to respond to chemotherapy. Management of NSCLC must include strategies to improve various aspects of QOL, nutritional status and pulmonary reserve to achieve comprehensive benefit.

Survival in small cell lung cancer in India: prognostic utility of clinical features, laboratory parameters and response to treatment.

BACKGROUND: Predictors of survival and response to treatment in patients with small cell lung cancer (SCLC) are ill-defined and unclear. In an attempt to assess the impact of common presenting symptoms and laboratory values on survival, we undertook this retrospective review of patients with SCLC. To our knowledge, there is no study on survival in SCLC patients from the Indian subcontinent. DESIGN: Retrospective Cohort study. MATERIALS AND METHODS: All newly diagnosed small cell lung cancer cases from December 2001 through December 2004, were identified and clinical data on presenting symptoms and laboratory findings from their hospital records, noted. The influence of various pretreatment factors on survival was investigated using Kaplan-Meier plots and Cox multivariate regression model. RESULTS: 76 subjects were included (84% males, 91% smokers). 57% patients had five or more symptoms at presentation. Cumulative symptom burden was strongly associated with survival (P =0.02). Survival was also significantly related with Karnofsky performance status (KPS) (P =0.04), disease extent (P =0.03) and symptomatic response to treatment (P< 0.001). Patients with higher hemoglobin (P =0.02), serum sodium (P =0.04) and serum globulin (P =0.02), survived significantly longer. By multivariate regression analysis, hemoglobin, KPS and brain metastases, were significant predictors of survival (P =0.01, P =0.02, P< 0.01 respectively). CONCLUSION: Cumulative symptom burden, KPS, disease extent and symptomatic assessment of improvement after treatment, are useful predictors of survival. This has important clinical implications, keeping in view, the infrastructure and cost involved in more objective tests like CT scan, for evaluation of disease extent and prognosis. These findings can provide a simple basis for predicting prognosis in small cell lung cancer, especially in developing countries like ours.

Change in tissue thromboplastin content of brain following trauma.

BACKGROUND: Tissue thromboplastin (TTP) is an integral membrane protein contributing to coagulopathy after trauma of brain, which is a rich source of TTP. AIMS: A study was undertaken to establish the TTP content of various areas of normal brain and estimate the changes in TTP activity of brain in response to varying degrees of trauma. MATERIALS AND METHODS: Samples from different areas of brain of ten cadavers were used as controls and they were compared with contused brain tissue obtained after surgery in 25 head injury (HI) patients of varying severity. RESULTS: In the study group, the TTP activity of the frontal, parietal, and temporal lobes after HI was significantly raised in contrast to that of the control group. The TTP activity was also significantly higher in the severe HI patients than those having moderate HI. The mode of injury and the time lapse after HI had no significant bearing on the TTP activity. Subjects above 40 years of age demonstrated a higher mean TTP activity after HI, though it was not statistically significant. CONCLUSION: The study provides quantitative data on TTP activity of normal brain and highlights the role of TTP in coagulopathy following HI through its increased activity after HI, more so in the severe HI group.

Influence of zinc on the status of hepatic trace elements and biokinetics of 65Zn in ethanol treated rats.

Whole body counting studies of 65Zn indicated that the Tb1 (the faster component) was significantly decreased while the slower component (Tb2) was increased significantly following ethanol treatment. Interestingly, following zinc treatment to ethanol treated rats, slower component (Tb2) of 65Zn came back to within normal limits while the faster component (Tb1) got significantly elevated in comparison to ethanol treatment. Percent uptake values of 65Zn were found to be increased in liver, intestine, muscle, brain and kidney, and decreased in bone under alcoholic conditions. Interestingly, the uptake values of 65Zn in all the organs except muscle were reverted back to within normal limits upon zinc supplementation to these ethanol intoxicated animals. A significant decrease in zinc contents was noticed in ethanol treated rats, which, however, were raised to normal levels upon zinc supplementation: Copper levels, on the other hand, were significantly enhanced in both ethanol fed and combined ethanol + zinc treated rats. Calcium levels were significantly decreased in both ethanol and zinc treated rats, which however were further reduced upon zinc supplementation to ethanol fed rats. However, no significant change was observed in the concentrations of sodium and potassium in any of the treatment groups. In conclusion, zinc appears to play a protective role by normalizing the turnover of 65Zn in whole body as well as in its uptake in different organs under alcoholic conditions.

Non small cell lung cancer (NSCLC): current status and future prospects.

The incidence of lung cancer is rising dramatically and it is now the commonest cause of mortality and morbidity not only in the industrialised countries, but in developing nations like India as well. Tobacco smoking has consistently been demonstrated to be an important aetiological factor, though lung cancer occurs in non-smokers also. In spite of great advances in radiological and molecular diagnostic techniques, the ideal screening marker for early detection of lung cancer has still not been found. Histological diagnosis and staging is essential for selecting the mode of therapy in patients with lung cancer. Stages I and II are amenable to surgery. However, advanced stage III and IV need an individualised combination of surgery, chemotherapy and radiotherapy. With a better understanding of the cellular mechanisms operating in carcinogenesis, newer target specific modalities are being developed and tested in order to stem this disease, which threatens to assume epidemic proportions.

Possible relationship between phenylthiocarbamide taste sensitivity and epilepsy.

The study was based on the data of a sample of 400 epileptic patients (200 idiopathic and 200 symptomatic) and 100 normal healthy individuals serving as controls. The PTC threshold distribution was bimodal. The number of non-tasters among idiopathic epileptics (35.5%) and symptomatic epileptics (32.5%) was significantly higher than controls (20%). The relative incidence of non-tasters in idiopathic and symptomatic epilepsies was 2.20 and 1.93 respectively. There is evidence that non-tasters tend to ingest a greater quantity of bitter tasting goitrogenic substances present naturally in edible plants which in turn exert greater thyroid stress in non-tasters or less sensitive tasters. Such a stress during intrauterine or early childhood growth and development might have affected neurological maturation which in turn made them more susceptible to epilepsy than tasters, who faced lesser stress.

A clinical assessment of the effectiveness of mouthwashes in comparison to toothbrushing in children.

The study compared the efficacy of unsupervised tooth-brushing done once a day before breakfast (phase 1), with twice daily mouthrinsing with the three different commercially available mouthwashes containing 0.2% sodium fluoride (phase 2), a combination of 0.03% triclosan and 0.05% sodium fluoride (phase 3), and 0.2% chlorhexidine (phase 4) in 20 children aged 13-14 year, in reducing dental plaque formation. The results showed that there was a statistically significant difference in plaque reduction between phases 1 & 2; 1 & 3; 2 & 4 and 3 & 4. The mandibular arch harboured more plaque than the maxillary arch in phase 1 (p<0.05). Irrespective of the mouthwash used, the lingual/palatal surfaces had less plaque than the facial surfaces (p<0.05). The mean cumulative plaque scores of the mandibular lingual surfaces was more in comparison to the maxillary palatal surfaces in phases 1, 2 and 3 (p<0.05). It was therefore, concluded that 0.2% chlorhexidine was comparable to tooth brushing done once a day, before breakfast.

Energy cost and cardiorespiratory changes during the practice of Surya Namaskar.

Surya Namaskar (SN), a group of Yogic exercise consists of a set of twelve postures which is practiced by some of the yoga practitioners. The present study was undertaken to observe critically the energy cost and different cardiorespiratory changes during the practice of SN. Twenty-one male volunteers from the Indian Army practiced selected Yogic exercises for six days in a week for three months duration. The Yogic practice schedule consisted of Hatha Yogic Asanas (28 min), Pranayama (10.5 min) and Meditation (5 min). In the Yogic practice schedule 1st they practiced Kapal Bhathi (breathing maneuvers) for 2 min then Yogamudra (yogic postural exercise) for 2 min, after that they took rest until oxygen consumption and heart rate (HR) came to resting value. Subsequently subjects performed SN for 3 min 40 seconds on an average. After three months of training at the beginning of the fourth month subjects performed entire Yogic practice schedule in the laboratory as they practiced during their training session and experiments were carried out. Their pulmonary ventilation, carbondioxide output, Oxygen consumption, HR and other cardiorespiratory parameters were measured during the actual practice of SN. Oxygen consumption was highest in the eighth posture (1.22+/-0.073 1 min(-1)) and lowest in the first posture (0.35+/-0.02 1 min(-1)). Total energy cost throughout the practice of SN was 13.91 kcal and at an average of 3.79 kcal/min. During its practice highest HR was 101+/-13.5 b.p.m. As an aerobic exercise SN seemed to be ideal as it involves both static stretching and slow dynamic component of exercise with optimal stress on the cardiorespiratory system.
