    Abstract - The Internet brought about the phenomenon known as Cyber-space which is boundless in nature. It is one of the fastest-growing areas of technical infrastructure development over the past decade. Its growth has afforded everyone the opportunity to carry out one or more transactions for personal benefits. The African continent; often branded as ‘backward’ by the Western press has been able to make substantial inroads into the works of Information and Computer Technology (ICT). This rapid transition by Africans into ICT power has thus opened up the opportunities for Cybercriminal perpetrators to seek and target victims worldwide including America for personal financial gains. This existential threat has been growing in bounds and leaps over the past few years that the news media has been awash with cyber-attacks from African countries including Nigeria, South Africa, Ghana, Zimbabwe, and a host of other African nations. There have been several academic research and articles published on the African cyber-criminal activities by several authors; most of which are in silos and in non-subject specific databases everywhere. Our sponsored summer long project therefore re-analyzed the African style cyber- attacks culminating in the creation of an Access based database that captured the pertinent data about the reported cases through the use of secondary data sources

    <p>Abstract</p> <p>Background</p> <p>We undertook a needs assessment exercise using questionnaire survey of junior doctors' knowledge and beliefs concerning evidence-based medicine (EBM) and critical literature appraisal, as this is a core competence in postgraduate medical education.</p> <p>Methods</p> <p>We surveyed 317 junior doctors in various specialities in the UK West Midlands Deanery. Using validated questionnaires we compared the needs of different trainee groups. Results overall were internally consistent (Cronbach's alpha 0.929).</p> <p>Results</p> <p>Respondents' generally felt that they had poor training in EBM (Mean score 2.2, possible range 1 – 6) and that they needed more education (Mean score 5.3, possible range 1–6). Male trainees felt more confident at evaluating statistical tests than females (p = 0.002). Female trainees considered patient choice above the evidence more often than males (p = 0.038). Trainees from surgical speciality felt more confident at assessing research evidence (p = 0.009) whereas those from medical speciality felt more confident at evaluating statistical tests (p = 0.038) than other specialities. However, non-surgical specialities tended to believe that EBM had little impact on practice (p = 0.029). Respondents who had been qualified for 11 years or over felt overall more confident in their knowledge relating to EBM than those who had been qualified less than 10 years. In particular, they felt more confident at being able to assess study designs (p = < 0.001) and the general worth of research papers (p = < 0.001). Trainees with prior research experience were less likely to find original work confusing (p = 0.003) and felt more confident that they can assess research evidence (p = < 0.001) compared to those without previous research experience. Trainees without previous research experience felt that clinical judgement was more important than evidence (p = < 0.001).</p> <p>Conclusion</p> <p>There is a perceived deficit in postgraduate doctors' EBM knowledge and critical appraisal skills. Learning needs vary according to gender, place of basic medical qualification, time since graduation, prior research experience and speciality. EBM training curricular development should take into account the findings of our needs assessment study.</p

    BACKGROUND: The Internet is the world's largest network of information, communication and services. Although the Internet is widely used in medicine and has made significant impact in research, training and patient care, few studies had explored the extent to which Nigerian physicians use Internet resources for patient care. The objective of this study was to assess physicians' use of the Internet for health information for patient care. METHOD: 172 physicians at the University College hospital (UCH) Ibadan, Nigeria; completed a 31-item, anonymous, standardized questionnaire. The Epi-Info software was used for data analysis. RESULTS: The mean age of the respondents was 31.95 years (SD 4.94). Virtually all (98%) the respondents had used the Internet; 76% accessed it from cyber cafes. E-mail was the most commonly used Internet service (64%). Ninety percent of the respondents reported they had obtained information from the Internet for patient care; of this number, 76.2% had searched a database. The database most recently searched was MEDLINE/PubMed in 99% of cases. Only 7% of the respondents had ever searched the Cochrane Library. More than half (58.1%) perceived they had no confidence to download full-text articles from online sources such as the Health Internetwork Access to Research Initiative (HINARI). Multiple barriers to increased use of the Internet were identified including poor availability of broadband (fast connection speed) Internet access, lack of information searching skills, cost of access and information overload. CONCLUSION: Physicians' use of the Internet for health information for patient care was widespread but use of evidenced-based medicine resources such as Cochrane Library, Up-to-date and Clinical Evidence was minimal. Awareness and training in the use of EBM resources for patient care is needed. Introduction of EBM in the teaching curriculum will enhance the use of EBM resources by physicians for patient care

    Identification of Multiple HPV Types on Spermatozoa from Human Sperm Donors

    Human papillomaviruses (HPV) may cause sexually transmitted disease. High-risk types of HPV are involved in the development of cervical cell dysplasia, whereas low-risk types may cause genital condyloma. Despite the association between HPV and cancer, donor sperm need not be tested for HPV according to European regulations. Consequently, the potential health risk of HPV transmission by donor bank sperm has not been elucidated, nor is it known how HPV is associated with sperm. The presence of 35 types of HPV was examined on DNA from semen samples of 188 Danish sperm donors using a sensitive HPV array. To examine whether HPV was associated with the sperm, in situ hybridization were performed with HPV-6, HPV-16 and -18, and HPV-31-specific probes. The prevalence of HPV-positive sperm donors was 16.0% and in 66.7% of these individuals high-risk types of HPV were detected. In 5.3% of sperm donors, two or more HPV types were detected. Among all identified HPV types, 61.9% were high-risk types. In situ hybridization experiments identified HPV genomes particularly protruding from the equatorial segment and the tail of the sperm. Semen samples from more than one in seven healthy Danish donors contain HPV, most of them of high-risk types binding to the equatorial segment of the sperm cell. Most HPV-positive sperm showed decreased staining with DAPI, indicative of reduced content of DNA. Our data demonstrate that oncogenic HPV types are frequent in men

    Large expert-curated database for benchmarking document similarity detection in biomedical literature search

    Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency–Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research

    CITATION: Olatunbosun, O. D., Esterhuizen, T. M. & Wiysonge, C. S. 2017. A cross sectional survey to evaluate knowledge, attitudes and practices regarding seasonal influenza and influenza vaccination among diabetics in Pretoria, South Africa. Vaccine, 35(47):6375-6386, doi:10.1016/j.vaccine.2017.10.006.The original publication is available at https://www.journals.elsevier.com/vaccineBackground: In South Africa, influenza vaccination is recommended to all diabetics. However, vaccinationcoverage among diabetics remains low. Therefore, this study aimed to explore the knowledge, attitudes,and practices among peoplewith diabetes in Pretoria regardingseasonalinfluenza and influenza vaccination.Method: A cross-sectional survey was conducted among type 1 and 2 diabetes mellitus patients whoattended diabetic clinics in two major tertiary hospitals in Pretoria, South Africa from October toDecember 2015. The pilot-tested questionnaire consists of 32 quantitative questions that covered seasonalinfluenza and influenza vaccination in terms of the patient’s demographics, medical history and knowledge,attitudes and practices.Results: A total of 292 completed questionnaires were received with a response rate of 70.0%. Of these, 162participants (55.5%) believed that influenza is the same as common cold. While 96 (32.9%) participants wereawarethatthey were at higherrisk of complicationsof influenza,only 86 (29.5%) participantsconsidered vac-cination as an effective means in preventing seriousinfluenza-relatedcomplication.Even though 167 (57.2%)participants had heard of the vaccine to prevent influenza, only 84 (28.8%) participants were previously vac-cinated. Multivariate analysis shows that participants with good attitude score for influenza vaccinationwere 18.4 times more likely to be vaccinated compared with those with poor attitude score (OR =18.4,95%CI. 5.28–64.10, p = .001). Among those previously vaccinated, advice from their doctors (82/84, 97.6%)was the main factor encouraging vaccination. Top reasons given by participants who had never been vacci-nated before (208/292, 71.2%) include use of alternative protection (107/208, 51.4%) and that vaccination isnot necessary because flu is just a minor illness (93/208, 44.7%).Conclusion: Uptake of seasonal vaccination among diabetics in Pretoria is low. Level of knowledge and per-ception are the main barriers to vaccination. Health care provider’s advice may be an important key predictorof previous influenza vaccination and they should continue to educate and encourage all diabetics to get vac-cinated for influenza at least once yearly.https://www.sciencedirect.com/science/article/pii/S0264410X17313701Publisher's versio
