    Abstract: Over a period of 18 years, 39 cases of cardiac tumors were operated upon in the Department of Cardiothoracic Surgery at the Postgraduate Institute of Medical Education and Research, Chandigarh. These included 34 (87%) patients with benign tumors and 5 (13%) patients with primary malignant tumors. All the benign tumors were myxomas, of which 31 (91.2%) were in the left atrium and 3 (8.8%) in right atrium. Primary malignant tumors comprised 2 rhabdomyosarcomas, 1 angiosarcoma, 1 lymphoma and 1 case of pleomorphic malignant fibrous histiocytoma. The diagnosis was established by echocardiography, angiocardiography and computed tomography. In one case the diagnosis was made at autopsy. All myxomas, except tricuspid valve myxoma, were removed completely through right atrial or biatrial approach with the use of cardiopulmonary bypass. Four cases of primary malignant tumors were non-resectable. Near total resection of a malignant fibrous histiocytoma arising from the right middle pulmonary vein and left atrial junction was achieved. There were 2 operative deaths (5.1 %). The follow-up ranged from 3 months to 10 years with a mean of 5.7 years. There was 1 recurrence (2.9%) in the benign group. In the malignant group, 3 cases (60%) died within 5 to 8 months of surgery due to further local and metastatic spread of the tumor. The case of malignant fibrous histiocytoma was treated with postoperative radiotherapy to the right mediastinum and is doing well at follow-up 3 months after surgery.

    Abstract: There is currently conflicting evidence surrounding the effects of obesity on postoperative outcomes. Previous studies have found obesity to be associated with adverse events, but others have found no association. The aim of this study was to determine whether increasing body mass index (BMI) is an independent risk factor for development of major postoperative complications. Methods This was a multicentre prospective cohort study across the UK and Republic of Ireland. Consecutive patients undergoing elective or emergency gastrointestinal surgery over a 4-month interval (October–December 2014) were eligible for inclusion. The primary outcome was the 30-day major complication rate (Clavien–Dindo grade III–V). BMI was grouped according to the World Health Organization classification. Multilevel logistic regression models were used to adjust for patient, operative and hospital-level effects, creating odds ratios (ORs) and 95 per cent confidence intervals (c.i.). Results Of 7965 patients, 2545 (32·0 per cent) were of normal weight, 2673 (33·6 per cent) were overweight and 2747 (34·5 per cent) were obese. Overall, 4925 (61·8 per cent) underwent elective and 3038 (38·1 per cent) emergency operations. The 30-day major complication rate was 11·4 per cent (908 of 7965). In adjusted models, a significant interaction was found between BMI and diagnosis, with an association seen between BMI and major complications for patients with malignancy (overweight: OR 1·59, 95 per cent c.i. 1·12 to 2·29, P = 0·008; obese: OR 1·91, 1·31 to 2·83, P = 0·002; compared with normal weight) but not benign disease (overweight: OR 0·89, 0·71 to 1·12, P = 0·329; obese: OR 0·84, 0·66 to 1·06, P = 0·147). Conclusion Overweight and obese patients undergoing surgery for gastrointestinal malignancy are at increased risk of major postoperative complications compared with those of normal weight.

    Abstract: Postoperative acute kidney injury (AKI) is a common complication of major gastrointestinal surgery with an impact on short- and long-term survival. No validated system for risk stratification exists for this patient group. This study aimed to validate externally a prognostic model for AKI after major gastrointestinal surgery in two multicentre cohort studies. Methods The Outcomes After Kidney injury in Surgery (OAKS) prognostic model was developed to predict risk of AKI in the 7 days after surgery using six routine datapoints (age, sex, ASA grade, preoperative estimated glomerular filtration rate, planned open surgery and preoperative use of either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker). Validation was performed within two independent cohorts: a prospective multicentre, international study (‘IMAGINE’) of patients undergoing elective colorectal surgery (2018); and a retrospective regional cohort study (‘Tayside’) in major abdominal surgery (2011–2015). Multivariable logistic regression was used to predict risk of AKI, with multiple imputation used to account for data missing at random. Prognostic accuracy was assessed for patients at high risk (greater than 20 per cent) of postoperative AKI. Results In the validation cohorts, 12.9 per cent of patients (661 of 5106) in IMAGINE and 14.7 per cent (106 of 719 patients) in Tayside developed 7-day postoperative AKI. Using the OAKS model, 558 patients (9.6 per cent) were classified as high risk. Less than 10 per cent of patients classified as low-risk developed AKI in either cohort (negative predictive value greater than 0.9). Upon external validation, the OAKS model retained an area under the receiver operating characteristic (AUC) curve of range 0.655–0.681 (Tayside 95 per cent c.i. 0.596 to 0.714; IMAGINE 95 per cent c.i. 0.659 to 0.703), sensitivity values range 0.323–0.352 (IMAGINE 95 per cent c.i. 0.281 to 0.368; Tayside 95 per cent c.i. 0.253 to 0.461), and specificity range 0.881–0.890 (Tayside 95 per cent c.i. 0.853 to 0.905; IMAGINE 95 per cent c.i. 0.881 to 0.899). Conclusion The OAKS prognostic model can identify patients who are not at high risk of postoperative AKI after gastrointestinal surgery with high specificity.

    Abstract: Global Warming is now becoming a challenge for survival of species on Earth and draws attention of many modern societies, power and energy engineers, academicians, researchers and stakeholders to go for deeper study. During the 21st centuries, the environmental consequences of increased levels of atmospheric carbon dioxide lead to the considerable impacts upon Earth's weather and climate change. It is due to faster consumption of hydrocarbon fuel in the transport sector which is posing global threat of increase of green house gases through tail pipe emission. It is also a known fact that major greenhouse gas H2O substantially warms the Earth, minor greenhouse gases such as CO2 have also considerable effect. To sequestrate the Carbon Di-oxide and Carbon Mono-oxide many methods were tried to reduce the impact of environmental issues. But it is noticed that plant and trees are the most effective source to absorb the carbon being released through green house gases. In this paper a study has been carried out to focus on planting trees, that forms a tunnel when matured, along roadside to sequestrate the carbon released from exit gases of transport, as vehicles are increasing every year in manifold especially in developing country like India. Authors have taken many readings at different places in Lucknow City and concluded that if trees are planted along roadsides, the carbon can be sequestrated optimally, if green coverage tunneling with sufficient matured trees is present along road sides. Thus planting trees according to the rate of release of carbon can be the most effective solution for curbing the impact of climate change. This can make Green and Clean Environment and need maximum coverage by media too so that people may start planting trees in residential areas also.

    Abstract: World's about 80% of the energy consumption is sustained by the extraction of fossil fuels, which consists of oil, coal and gas. Another non-renewable resource that is exploited by humans is subsoil minerals such as precious metals that are mainly used in the production of industrial commodities. It is only because of the increasing population and subsequent growth of materialistic attitude in human's behavior that has lead our planet to an exhaustible measure and subsequent release of harmful carbon particulate from the vehicles’ exhaust pipes also cannot be overlooked as it contains many harmful Green House Gases like: Carbon-dioxide, Carbon-monoxide, Methane etc. emerging out of Thermal Power Houses and Industries. This is also causing environmental damage and changes in the and atmosphere around earth's surface. Unfortunately, our future generation may face awful challenges for their survival due to these changes. Although, scientists and environmentalists, are seriously focusing to research an alternative energy to be helpful for the development of society and curbing the challenging climatic conditions. India being a geographically very rich pasture and has more than 10 months sun-shine (i.e. 300 days against 365 days) in a year. Thus, Solar Energy can be a better alternative in India to be exploited as a major source of Electric Power Deficit. Currently in India, Installed capacity of Power is 302087.87 MW and Generation is 104867.30 MW against Peak demand of 148166 MW (a deficit of around 45,000MW). As an experiment in Lucknow, if an average house-hold installs 2 kWh Roof Top Solar Power Generation, it will help to generate around 2-2.50 million units (2,000-2,500MW) in a year by approx. 10 lacks existing houses in Lucknow and light additionally more than 100-150 villages with current installed capacity of power generation under Solar Green Energy Potential and without damaging Environment. Thus, Solar Roof Top Power Generation can create almost surplus power in India by the year 2020 even if 50% of houses of countrymen decide to place Solar Roof Top Panels in their houses under major awareness programme.

    Abstract: Magnesium alloys are excellent choice for automobile, aerospace, and computer components owing to their light weight, unique physical and mechanical properties. However, poor corrosion resistance has restricted their applications in aggressive environments. The surface coating is one of the viable options to reduce the susceptibility of magnesium alloys to corrosion. The present study focuses on the effect of heat treatment of AZ91 magnesium alloy, for different durations at 400 °C, prior to electroless Ni-P deposition on corrosion resistance. The microstructure and elemental analysis of the heat-treated specimens are performed using SEM and EDS techniques respectively. It is observed that the duration of heat treatment has a significant effect on the surface morphology and microstructure of the alloy. The precipitates in the cast alloy (enriched with Mg and Al) fragmented and the transformed into a new Al and Zn rich phase, after 12 h heat treatment. The dissolution of precipitates, however, observed on heating further to 24 h and exhibited relatively a lesser corrosion current density. The dense electroless Ni-P deposition is formed on the alloy heat treated for 24 h. The corrosion behavior of the single Ni-P layer on the heat treated (for 12 h) and untreated alloy show a marked deterioration, as investigated by the anodic polarization and electrochemical impedance spectroscopy (EIS) techniques. Relatively a better corrosion performance is seen for the double-layer Ni-P deposition. The duplex layer coatings on the as cast and heat treated for 24 h at 400 °C substrates showed an improved corrosion resistance compared to that on the 12 h heat treated substrate.
