Risk factors for cardiovascular disease in school children--a pilot study.

OBJECTIVE: To assess the frequencies of risk factors for cardiovascular disease in school children. The information may help in designing interventions aimed at modifying unhealthy lifestyle in children, which may reduce the later incidence of cardiovascular disease in adults. METHODS: A cross-sectional study was conducted on 206 students (ages 14-18 years), enrolled in higher secondary school. Students were interviewed about their lifestyles, family history of cardiovascular disease and its risk factors. Moreover, they were assessed for height, weight and blood pressure. RESULTS: Twenty nine percent of the children were physically inactive, 31% were taking unhealthy diet daily, 21% were overweight (BMI \u3e or = 25) and 6% were smokers. History of paternal smoking was reported by 36% of the children, and among them 76% of fathers smoked in the presence of their children. Family history of cardiac disease, hypertension and diabetes were positive in 4%, 23% and 16% of the children respectively. Overall, 58% of the children had at least one modifiable risk factor. CONCLUSION: Majority of the children had modifiable risk factors for cardiovascular disease. Prevention efforts are required early in life, using strategies for behavioral modification and health promotion

Intravesical foreign body: tertiary care center experience from Pakistan.

Foreign body in bladder is relatively uncommon condition with variable presentations. Literature is limited to case reports and small series from region. Therefore, we planned this study to review our experience regarding intravesical foreign body. This retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised 14 patients having intravesical foreign bodies from March 1989 to March 2013. Demographics, presentation, mode of insertion, type of foreign body and management were noted. Of the 11(78.6%) patients included in the study, 10(90.9%) patients were male and 1(9.1%) was female. The mean age was 51± 20 years. In 5(45.5%) patients, foreign bodies reached bladder by iatrogenic route followed by self-insertion in 4(36.4%) patients. Retrieved foreign bodes included piece of Foley\\u27s catheter, electric wire, ureteric stent, plastic material, double-J stent pusher, Endo gastrointestinal (GI) staples, sticks of broom and bomb shrapnel. All patients were managed successfully with endoscopic removal. However, 5(45.5%) patients required additional urological procedures. This could represent a urologic challenge. Careful history and symptoms could lead to further investigations

Evaluating Two-Stream CNN for Video Classification

Videos contain very rich semantic information. Traditional hand-crafted features are known to be inadequate in analyzing complex video semantics. Inspired by the huge success of the deep learning methods in analyzing image, audio and text data, significant efforts are recently being devoted to the design of deep nets for video analytics. Among the many practical needs, classifying videos (or video clips) based on their major semantic categories (e.g., "skiing") is useful in many applications. In this paper, we conduct an in-depth study to investigate important implementation options that may affect the performance of deep nets on video classification. Our evaluations are conducted on top of a recent two-stream convolutional neural network (CNN) pipeline, which uses both static frames and motion optical flows, and has demonstrated competitive performance against the state-of-the-art methods. In order to gain insights and to arrive at a practical guideline, many important options are studied, including network architectures, model fusion, learning parameters and the final prediction methods. Based on the evaluations, very competitive results are attained on two popular video classification benchmarks. We hope that the discussions and conclusions from this work can help researchers in related fields to quickly set up a good basis for further investigations along this very promising direction.Comment: ACM ICMR'1

Impact of duration of antibiotic prophylaxis on rates of surgical site infection (SSI) in patients undergoing mastectomy without immediate reconstruction, comparing a single prophylactic dose versus continued antibiotic prophylaxis postoperatively: A multicentre, double-blinded randomised control trial protocol

Introduction: In breast surgeries, prophylactic antibiotics given before the surgical incision as per Joint Commission Surgical Care Improvement Project guidelines have been shown to decrease the rate of postoperative infections. There is, however, no clear consensus on postoperative antibiotic prophylaxis in patients undergoing mastectomy with indwelling drains. This trial protocol proposes to study the difference in rates of surgical site infection (SSI) with or without continuation of postoperative antibiotics in patients undergoing mastectomy without immediate reconstruction and with indwelling drains.Methods and analysis: In this multicentre, double-blinded clinical trial, all patients undergoing mastectomy (without immediate reconstruction) will receive a single prophylactic dose of preoperative antibiotics at induction of anaesthesia and will then get randomised to either continue antibiotic prophylaxis or a placebo postoperatively, for the duration of indwelling drains. The primary and secondary outcomes will be development of an SSI and antibiotic-associated adverse effects, respectively. Data will be collected through a standard questionnaire by wound assessors. Intention-to-treat analysis will be carried out using STATA V.12. For categorical variables, frequencies and percentages will be assessed by χ2 test/Fisher\u27s exact test as appropriate. The quantitative variables will be computed by their mean±SD or median (IQR) and will be assessed by independent t-test/Mann-Whitney test as appropriate. Unadjusted and adjusted relative risk with their 95% CI will be reported using Cox proportional regression. A p value of \u3c0.05 will be considered statistically significant.Ethics and dissemination: Ethical approval has been obtained from each site\u27s Ethical Review Board. The study background and procedure will be explained to the study participants and informed consent will be obtained. Participation in the study is voluntary. All data will be deidentified and kept confidential. The study findings will be published in scientific media and authorship guidelines of International Committee of Medical Journal Editors will be followed.Trial registration number: NCT04577846.

Hybrid PV System with High Speed Flywheel Energy Storage for Remote Residential Loads

Due to low system inertia in microgrids, frequencies may vary rapidly from the nominal value, leading to the complete blackout of the system unless there is an adequate spinning reserve available for balancing the supply with the demand load. This issue of instability in microgrids under islanded operation has attracted particular attention recently. A diesel generator is considered to be an ideal spinning reserve to provide back-up power to the load along with the renewable energy source in islanded system. However, the high maintenance cost and CO2 emissions of diesel generator are detrimental factors which have inspired searches for more cost effective and cleaner technologies. The integration of an energy storage system (ESS) in islanded system along with generator not only reduces generator maintenance costs but also reduces the CO2 emissions by limiting its operating hours. This paper proposes an islanded PV hybrid microgrid system (PVHMS) utilizing flywheel energy storage systems (FESS) as an alternative to battery technology to support the PV system and meet the peak demand of a small residential town with 100 dwellings. The diesel generator is used in the islanded system as a spinning reserve to maintain the stability of the islanded system when the PV system and flywheel storage cannot meet the load demand. Results of analysis of such a system demonstrate that flywheel energy storage technology of appropriate size offers a viable solution to support the operation of the standalone PV system. Furthermore, the reduction in CO2 emissions and fuel consumption has been quantified as compared with the case with flywheel energy storage systems which means the diesel generator but always be operating

Preliminary selection and evaluation of fungicides and natural compounds to control grey mold disease of rose caused by Botrytis cinerea

Botrytis cinerea es un hongo patógeno de las plantas que causa la enfermedad del moho gris del rosal (Rosa indica L.). La búsqueda de estrategias de control nuevas y alternativas respetuosas con el medio ambiente, en lugar de los productos químicos peligrosos, para diferentes enfermedades de los cultivos es un paso crucial y saludable para hacer frente a los retos actuales del cambio climático. Por lo tanto, este estudio tuvo como objetivo evaluar la eficacia de diferentes extractos botánicos y agentes de biocontrol (biopesticidas) junto con diferentes fungicidas contra B. cinerea en condiciones in vitro. Se utilizaron tres concentraciones diferentes, a saber, 100, 200 y 300 ppm de cinco fungicidas, a saber, Acrobate, Melody, Cabrio top, Antracol y oxicloruro de cobre, extractos botánicos de ocho plantas Dhatura, Jengibre, Aak, Neem y Cebolla, en tres dosis diferentes de 5, 10 y 15%, El estudio de la incidencia de la enfermedad% de moho gris en el cultivo de rosas en la región muestra que la región de Hyderabad tiene un máximo (60%) de incidencia de la enfermedad en comparación con la región de Tandojam (40%). Entre los fungicidas, el Cabrio top redujo significativamente el crecimiento lineal de colonias (31 mm) de B. cinerea a una concentración de 300 ppm. Entre los productos botánicos, el extracto de la planta de neem mostró significativamente el menor crecimiento de colonias (23,33 mm), seguido de la planta de jengibre (25 mm) y la planta de dhatura (26 mm). La mayor concentración de fungicidas y las dosis más altas (15%) de extractos botánicos resultaron significativamente eficaces para controlar el patógeno B. cinerea. Among biopesticides, Fusarium solani appeared prominent in reducing colony growth (25.16 mm) of the pathogen but the difference was not significant 300 with most of the tested biocontrol agents. La recomendación en este estudio es la alta capacidad de los extractos botánicos y agentes de biocontrol en la reducción del crecimiento de moho gris, considerando potencialmente su uso en lugar de fungicidas sintéticos y mayor seguridad para el ecosistema.Campus Ic

Comparative assessment of haematological profile in hatchery and riverine populations of Channa marulius

798-803Present study was conducted to assess the haematological profile of Channa marulius from hatchery and riverine populations. Blood samples were collected by caudal vein puncture. Significantly higher values (p ≤ 0.05) were recorded for various blood indices in hatchery populations as compared to those of riverine sources. Observed values of haematological parameters in hatchery populations were: Erythrocytes 4.90×106 cells µL-1, eosinophils 4.06 %, monocytes 5.53 %, haematocrit count 28.86 %, haemoglobin content 5.385 gdL-1, platelet distribution width 6.91 fL, red blood cell distribution width 23.83 fL, Procalcitonin 2.37 µL, mean corpuscular volume 7.87 fL and large platelet concentration ratio 14.64 %. In riverine populations, significantly higher values (p ≤ 0.05) for leucocytes count 5625×103 µL-1, mean cell haemoglobin 32.75 pg, mean corpuscular haemoglobin concentration 43.66 gdL-1 and mean cell volume 171.90 fL were observed as compared to those of hatchery populations. Conversely, non-significant (p ≥ 0.05) differences were observed with elevated values for neutrophils (14.042 %) in riverine fish populations as compared hatchery samples (13.896 %). Lymphocytes and platelets counts were 17.344 % and 33.742×103 µL-1, respectively in hatchery populations whereas in riverine populations these were 13.764 % and 33.896×103 µL-1, respectively. Physico-chemical parameters of sample water were observed to be in safe range throughout the study period. The observed variation in haematological profile between both groups is due to different inhabiting conditions that exert direct impacts on fish haematology
