Big data and a smarter university: a literature review

Using big data in a university is ‘the thing’ today since almost all information today is digitalized. Big data ensures better data processing, analysis and sharing, thus increasing productivity and researchers would have a great time doing their researches. A smart university is a university which uses technologies which could increase the productivity of knowledge management. Changing into a smart university is definitely a smart move because it is important to be competitive in a world full of formidable competitors. Research has proven that smart universities such as Caltech University and Northwestern University which are among the top universities in the world has also endeavored into the big data arena

Postoperative wound leak and anterior chamber reaction in patients undergoing phacoemulsification cataract surgery with sutured and sutureless corneal incisions

Purpose: To compare the rates of significant post operative wound leak and anterior chamber (AC) reaction in patients undergoing phacoemulsification cataract surgery with sutured and sutureless corneal incisions. Material and Methods: All eyes scheduled to have phacoemulsification surgery by two surgeons at two centers were selected. The first group of eyes underwent phacoemulsification surgery with 3.25 mm superior and superior-temporal clear corneal incisions. The incision was sutured using a single 10/0 nylon suture. The second group of eyes underwent an identical surgery, but the incision was not sutured. Patients were followed up at 24 hours, and 1 week and evaluated by slit lamp for wound leak (using Seidel\u27s Test) and AC cells and flare. Results: Forty eight eyes underwent surgery with sutured corneal incisions and 50 eyes underwent sutureless surgery. The mean age of patients in groups I and II were 61.2 years and 63.3 years, respectively. Following surgery, none of the patients in two groups showed wound leak at 1 day and 1 week. At the first post-op day, only 14.6% of eyes in group 1 showed AC reaction, compared to 32.0 % in group II (p = 0.04). At one week postop, 16.7% and 20.0% of eyes in Groups I and II showed AC reaction, respectively. However, the difference was not statistically significant (p = 0.67). Conclusions: The rates of postoperative wound leak and anterior chamber reaction in patients undergoing phacoemulsification cataract surgery with sutured and sutureless corneal incisions are not different. Thus sutured surgery offers no added advantages

Designing EthAKUL: A mobile just-in-time learning environment for bioethics in Pakistan

In developing countries such as Pakistan, bioethics has not been included in mainstream thinking in medical education. The authors’ experiences suggest that current methods of teaching bioethics are problematic as students are unable to translate theory to practice. Alternative pedagogies, such as just-in-time learning (JiTL) using mobile devices, may be able to foster the development and implementation of ethical reasoning among nurses, doctors, and medical and nursing students. This research was conceived to determine the effectiveness of mobile JiTL – anytime, anyplace learning through mobile devices – for teaching bioethics. After obtaining ethical clearance, a participatory design (PD) approach was adopted to ensure input from all stakeholders for the design of ‘EthAKUL’, comprising a mobile app, five modules and just-in-time pedagogy. The name of the app is an acronym evoking ethics, learning and the university where the project originated. As a part of the design process, three PD workshops were held with junior doctors, nurses, nursing students, medical students and bioethics teaching faculty, and five meetings were held with faculty members, to discuss functional specifications and user-acceptance testing of the app. The feedback related to the nature of common ethical issues encountered in clinical settings, the existing process of teaching and learning bioethics, and the requested features of the app were recorded. These data sets were analyzed and synthesized into functional and technical specifications for the mobile app. The software programmers developed the app with the close involvement of the stakeholders. The development of teaching content continued alongside this process. While this enabled EthAKUL’s developers to incorporate needs of all stakeholders, challenges were encountered in the process relating to the pragmatic and conceptual aspects of JiTL, ML and PD. We discuss the implications of this research in bringing about transformative changes in higher education

Causes of Smoking in College Students

This study was aimed at investigating smoking and causes of cigarette smoking among college students of Warsak Road Peshawar. The sample consisted of forty (N=40) students of Warsak Model School and College and Peshawar Public School and College. Average age of the students was 18.7. Among the 100 students, 40 were smokers while 60 were non-smokers. Convenient sampling technique was used for selection of the sample. Structured survey questionnaire was used for data collection. The objectives of the study were To provide an initial estimate on the frequency of cigarette smoking among students of college level on Warsak road Peshawar and explore causes of smoking in these students. Cross-sectional study design was used. The study was a small scale one due to limited financial resources and a short time frame. Students were busy in their annual exams and thus could not fully co-operate. The results revealed the main reasons for smoking were fashion and style, tension due to studies and family problems. Twenty-five (n=25) out of forty (n=40) students smoke more than 2 cigarettes per day. Out of forty (N=40) smoker students twenty-four (n=24) were introduced to smoking by their friends, 10 students by class-fellows, three (n=3) by relatives, one(n=1) by parents, two (n=2) by other people. 54 out of 60 non-smokers agreed that smoking is a bad habit. Cigarette smoking is very common among college students. Further in depth research is recommended to assess the frequency of smoking on a larger scale. Health education and awareness should be promoted in young adults in order to decrease the frequency of smoking

Review of PPX Business Models : Adaptability and Feasibility of PPX Models in the Equipment Manufacturing Industry

The overall purpose of this study is to understand how manufacturing companies have so far made use of and can make use of pay-per-x (PPX) business models (BMs) largely in capital product markets, and which mechanisms have helped them in the implementation. Through systematic literature approach this study analysed 14 research publications which exclusively focused on PPX business models. The differences between PPX business model patterns were studied from three perspective, namely criticality of product, need of process knowledge and complexity of the process and its output. We find out that the pay-per-outcome business model, is more prevalent for products which are critical, needs extensive process knowledge and are rather complex. In contrarily, pay-per-output business model is more prevalent when these conditions are not met. However, none of these three factors prevents implementing other type of PPX business model but rather specific business model is more feasible when specific conditions are met. This paper contributes a much more in-depth qualitative view on the patterns and related qualitative arguments for the useful application of PPX models in equipment manufacturing industries and helps to understand the differences between PPX business model types.acceptedVersionPeer reviewe

Biohydrogen production through dark fermentation from waste biomass:Current status and future perspectives on biorefinery development

Green and clean hydrogen production has become a significant focus in recent years to achieve sustainable renewable energy fuel needs. Biohydrogen production through the dark fermentation (DF) process from organic wastes is advantageous with its environmentally friendly, energy-efficient, and cost-effective characteristics. This article elucidates the viability of transforming the DF process into a biorefinery system. Operational pH, temperature, feeding rate, inoculum-to-substrate ratio, and hydrogen partial pressure and its liquid-to-gas mass transfer rate are the factors that govern the performance of the DF process. Sufficient research has been made that can lead to upscaling the DF process into an industrial-scale technology. However, the DF process cannot be upscaled at the current technology readiness level as a stand-alone technology. Hence, it requires a downstream process (preferably anaerobic digestion) to improve energy recovery efficiency and economic viability. The article also discusses the possible hydrogen purification and storage techniques for achieving fuel quality and easy accessibility. The article further tries to unfold the opportunities, challenges, and current scenario/future research directions to enhance hydrogen yield and microbial metabolism, depicting the commercialization status for biorefinery development. Finally, the current progress gaps and policy-level loopholes from the Indian perspective are highlighted by analyzing the strengths, weaknesses, opportunities, and threats

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Burden of cancer in the Eastern Mediterranean Region, 2005-2015: findings from the Global Burden of Disease 2015 Study

Fitzmaurice C, Alsharif U, El Bcheraoui C, et al. Burden of cancer in the Eastern Mediterranean Region, 2005-2015: findings from the Global Burden of Disease 2015 Study. INTERNATIONAL JOURNAL OF PUBLIC HEALTH. 2018;63(Suppl. 1):151-164.To estimate incidence, mortality, and disability-adjusted life years (DALYs) caused by cancer in the Eastern Mediterranean Region (EMR) between 2005 and 2015. Vital registration system and cancer registry data from the EMR region were analyzed for 29 cancer groups in 22 EMR countries using the Global Burden of Disease Study 2015 methodology. In 2015, cancer was responsible for 9.4% of all deaths and 5.1% of all DALYs. It accounted for 722,646 new cases, 379,093 deaths, and 11.7 million DALYs. Between 2005 and 2015, incident cases increased by 46%, deaths by 33%, and DALYs by 31%. The increase in cancer incidence was largely driven by population growth and population aging. Breast cancer, lung cancer, and leukemia were the most common cancers, while lung, breast, and stomach cancers caused most cancer deaths. Cancer is responsible for a substantial disease burden in the EMR, which is increasing. There is an urgent need to expand cancer prevention, screening, and awareness programs in EMR countries as well as to improve diagnosis, treatment, and palliative care services

Estimates, trends, and drivers of the global burden of type 2 diabetes attributable to PM2.5 air pollution, 1990-2019 : an analysis of data from the Global Burden of Disease Study 2019

Background Experimental and epidemiological studies indicate an association between exposure to particulate matter (PM) air pollution and increased risk of type 2 diabetes. In view of the high and increasing prevalence of diabetes, we aimed to quantify the burden of type 2 diabetes attributable to PM2.5 originating from ambient and household air pollution.Methods We systematically compiled all relevant cohort and case-control studies assessing the effect of exposure to household and ambient fine particulate matter (PM2.5) air pollution on type 2 diabetes incidence and mortality. We derived an exposure-response curve from the extracted relative risk estimates using the MR-BRT (meta-regression-Bayesian, regularised, trimmed) tool. The estimated curve was linked to ambient and household PM2.5 exposures from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019, and estimates of the attributable burden (population attributable fractions and rates per 100 000 population of deaths and disability-adjusted life-years) for 204 countries from 1990 to 2019 were calculated. We also assessed the role of changes in exposure, population size, age, and type 2 diabetes incidence in the observed trend in PM2.5-attributable type 2 diabetes burden. All estimates are presented with 95% uncertainty intervals.Findings In 2019, approximately a fifth of the global burden of type 2 diabetes was attributable to PM2.5 exposure, with an estimated 3.78 (95% uncertainty interval 2.68-4.83) deaths per 100 000 population and 167 (117-223) disability-adjusted life-years (DALYs) per 100 000 population. Approximately 13.4% (9.49-17.5) of deaths and 13.6% (9.73-17.9) of DALYs due to type 2 diabetes were contributed by ambient PM2.5, and 6.50% (4.22-9.53) of deaths and 5.92% (3.81-8.64) of DALYs by household air pollution. High burdens, in terms of numbers as well as rates, were estimated in Asia, sub-Saharan Africa, and South America. Since 1990, the attributable burden has increased by 50%, driven largely by population growth and ageing. Globally, the impact of reductions in household air pollution was largely offset by increased ambient PM2.5.Interpretation Air pollution is a major risk factor for diabetes. We estimated that about a fifth of the global burden of type 2 diabetes is attributable PM2.5 pollution. Air pollution mitigation therefore might have an essential role in reducing the global disease burden resulting from type 2 diabetes. Copyright (C) 2022 The Author(s).

Background Experimental and epidemiological studies indicate an association between exposure to particulate matter (PM) air pollution and increased risk of type 2 diabetes. In view of the high and increasing prevalence of diabetes, we aimed to quantify the burden of type 2 diabetes attributable to PM2·5 originating from ambient and household air pollution. Methods We systematically compiled all relevant cohort and case-control studies assessing the effect of exposure to household and ambient fine particulate matter (PM2·5) air pollution on type 2 diabetes incidence and mortality.
