A content-based recommender system for computer science publications

Abstract: As computer science and information technology are making broad and deep impacts on our daily lives, more and more papers are being submitted to computer science journals and conferences. To help authors decide where they should submit their manuscripts, we present the Content-based Journals & Conferences Recommender System on computer science, as well as its web service at http://www.keaml.cn/prs/ . This system recommends suitable journals or conferences with a priority order based on the abstract of a manuscript. To follow the fast development of computer science and technology, a web crawler is employed to continuously update the training set and the learning model. To achieve interactive online response, we propose an efficient hybrid model based on chi-square feature selection and softmax regression. Our test results show that, the system can achieve an accuracy of 61.37% and suggest the best journals or conferences in about 5 s on average.

Epidemiology of chronic rhinosinusitis: results from a cross-sectional survey in seven Chinese cities.

Abstract: Chronic rhinosinusitis (CRS) is characterized by inflammation of the mucosa of the nose and paranasal sinuses with a duration of at least 12 consecutive weeks and is a common otorhinolaryngologic disease that is frequently encountered in everyday practice (1). Although CRS is not a life-threatening disease, not all patients are cured or achieve control of their symptoms, even with maximal medical management or surgical intervention. The symptoms in CRS patients with (CRSwNP) and without nasal polyps (CRSsNP) are considerably overlapping, while patients with CRSwNP have higher symptom scores and more nasal symptoms (2). Patients with CRSwNP are particularly recalcitrant to usual therapies, and this type of CRS is increasingly prevalent (3). The persistent symptoms can result in facial pain/headache, impairments in general health, vitality and social functioning, stress disorders and other problems that affect patients’ lives and work (4–7). The European Position Paper on Rhinosinusitis and Nasal Polyps (EP3OS) group proposed clear guidelines for a symptom-based definition of rhinosinusitis that has been validated and accepted in epidemiological studies (1,8,9). The European postal survey of 57 128 adults in 12 countries reported that the overall prevalence of EP3OS-defined CRS was 10.9% and ranged from 6.9% to 27.1% in 19 centres (10). A recent survey reported a prevalence of EP3OS-defined CRS of 5.51% in Sao Paulo, Brazil (11). Some authors have used the data from the National Population Health Survey to estimate the prevalence of CRS and found prevalences of 6.95% in Korea (12) and 5.7% among female and 3.4% among male Canadians (13). The 2012 National Health Interview Survey of 34 525 adults found that 12% of adults have been told by a doctor or other health professional that they have sinusitis, and these self-reported doctor-diagnosed prevalences of sinusitis were 15% and 9% among males and females, respectively. The vital health statistic data revealed that CRS is more prevalent than other common chronic respiratory diseases, such as chronic obstructive pulmonary disease (3%) and asthma (8%) (14). Based on this high prevalence, some studies in the USA have claimed that CRS poses an enormous health and economic burden to individuals, the community and society (15). When accounting for the entire population into account, the health burden of CRS is speculated to be huge in Asia; nevertheless, little is known about the actual situation. A survey of 4554 Danes reported a CRS prevalence of 7.8% compared to the overall prevalence of 10.9% in 19 European centres (10,16). The National Health Interview Survey of US adults revealed a decreasing trend in CRS from 16% in 1997 to 14% in 2006 and 12% in 2012 (14,17,18). The literature suggests that the prevalence and patterns of CRS might vary by region and population and change over time due to environmental changes and the development of health care. The previous epidemiological data regarding CRS are mainly from western studies, and little is known regarding the potential socio-economic disparities. In Asia, large-scale epidemiological studies are required to update information about the prevalence of CRS, and such studies would provide information for the assessment of the disease burden and the development and promotion of public health policies associated with CRS. We conducted a cross-sectional investigation in seven major Chinese cities. This study aimed to provide a better understanding of the epidemiological characteristics of CRS, including its prevalence and associations with socio-economic factors and tobacco smoke.

The relationship of sleep duration and insomnia to risk of hypertension incidence: a meta-analysis of prospective cohort studies

Abstract: To assess whether habitual sleep duration or insomnia increase the incidence of hypertension. PubMed, EMBASE and Cochrane were searched without language restriction. Prospective cohort studies of adults with at least a 1-year follow-up duration were included. Habitual sleep duration or symptoms of insomnia were assessed as baseline exposure, and the outcome was incidence of hypertension. Subgroup, meta-regression and sensitivity analyses were conducted to assess heterogeneity, and Egger's test was used to assess publication bias. Eleven studies (17 cohorts) were included. Short sleep duration, sleep continuity disturbance (SCD), early-morning awakening (EMA) and combined symptoms of insomnia increased the risk of hypertension incidence (the relative risks (95% confidence intervals) were 1.21 (1.05–1.40) for short sleep duration, 1.20 (1.06–1.36) for SCD, 1.14 (1.07–1.20) for EMA and 1.05 (1.01–1.08) for combined insomnia symptoms). Less evidence exists to support conclusions about the association between long sleep duration or difficulty falling asleep (DFA) and hypertension incidence. No obvious heterogeneity or publication biases were found. Our meta-analysis demonstrates that short sleep duration and single/combined symptoms of insomnia (except DFA) are associated with an increased risk of hypertension incidence. It is important to consider sleep duration and insomnia during hypertension prevention and treatment. More laboratory studies on potential mechanisms and prospective observational studies with objective measures of sleep are needed.
