Abstract: Background: Waterpipe tobacco smoking has spread worldwide. However, the evaluation of scientific output in the field of waterpipe tobacco smoking has not been studied yet. The main objectives of this study were to analyze worldwide research output in the waterpipe tobacco smoking field, and to examine the authorship pattern and the citations retrieved from the Scopus database for over a decade. Methods: Data from January 1, 2003 through December 31, 2012 were searched for documents with specific words regarding waterpipe tobacco smoking as “keywords” in the title. Scientific output was evaluated based on a methodology developed and used in other bibliometric studies: (a) total and trends of contributions in waterpipe tobacco smoking research between 2003 and 2012; (b) authorship patterns and research productivity; (c) collaboration patterns; (d) the citations received by the publications; and (e) areas of interest of the published papers. Results: Worldwide there were 334 publications that met the criteria during the study period. The largest number of publications in waterpipe tobacco smoking were from the United States of America (USA) (33.5%), followed by Lebanon (15.3%), and France (10.5%). The total number of citations at the time of data analysis (October 18, 2013) was 4,352, with an average of 13 citations per document and a median (interquartile range) of 4.0 (1.0-16.0). The h-index of the retrieved documents was 34. The highest h-index by country was 27 for the USA, followed by 20 for Syrian Arab Republic and Lebanon. Conclusions: The present data reveal a promising rise and a good start for research activity in the field of waterpipe tobacco smoking. More effort is needed to bridge the gap in waterpipe smoking-based research and to promote better evaluation of waterpipe smoking, risks, health effects, or control services worldwide.

Abstract: Background: Electronic cigarettes (e-cigarettes) are battery-powered devices that vaporize a liquid solution to deliver a dose of inhaled nicotine to the user. There is ongoing debate regarding their regulation. Objectives: This comprehensive narrative review aimed to discuss key issues including usage patterns, health effects, efficacy in smoking cessation and regulatory concerns with a view to informing future regulation and research agendas. Methods: PubMed, Scopus and Web of Science databases were searched using the terms (electronic cigarettes OR e-cigarettes) for articles in English, relevant to humans and published during January 2009-January 2014. Results: The literature search revealed 37 relevant articles. Findings suggest that e-cigarettes are mostly used by middle-aged current smokers, particularly males, to help them for quitting or for recreation. E-cigarettes contain very low levels of multiple toxic substances such as formaldehyde and acrolein, but these levels are many times lower than those found in cigarettes. They were found to have effectiveness in aiding smoking cessation to a limited degree. Debate continues regarding regulating their use for cessation versus heavy restrictions to control recreational use on the basis that it perpetuates nicotine addiction. Conclusions: The cytotoxicity and long term health effects of e-cigarettes are unknown. Nevertheless the e-cigarette market continues to expand, largely driven by middle-aged smokers who claim to be using e-cigarettes in an attempt to reduce or quit smoking. E-cigarettes may have some potential as smoking cessation aids and, in the researchers’ view, should therefore be subject to further research and regulation similar to other nicotine replacement therapies.

Abstract: Pharyngolaryngeal cancer is one of the most common head and neck cancer worldwide, and the early diagnosis and prognosis prediction are still difficult because of lacking in reliable cell markers. Although the expression of CD44 has been reported to correlate with poor prognosis of pharyngolaryngeal cancer in most literatures, some controversies still exist. Since the limited patient numbers within independent studies, here we performed a meta-analysis to clarify the correlations between CD44 expression and clinicopathological features and prognosis in pharyngolaryngeal cancer. A search of Pub Med, ISI Web of Science and China National Knowledge Infrastructure databases (up to June 2013) was performed. Nineteen studies with 1,405 patients met the inclusion criteria. The expression of pan-CD44, including all variant isoforms, was detected in 58.0% (14.1-79.2%) specimens, while CD44-v6 (variant isoform 6 of CD44) was expressed in 54.8% (12-79.2%). In pooled analysis, CD44 expression was significantly associated with larger tumor size (T category, RR (relative risk) = 1.21, 95% CI: 1.01-1.46), lymph nodes metastasis (N category, RR = 1.94, 95% Cl: 1.38-2.73) and poor prognosis [3-year overall survival (OS): RR = 0.70, 95% CI: 0.53-0.91; 5-year OS: RR = 0.66, 95% CI: 0.66-0.94]. In the stratified analysis of CD44 isoforms, high expression of CD44-v6 was related with a poor 5-year OS rate (RR = 0.53, 95% CI: 0.37-077). We propose that CD44 expression is associated with tumor size, lymph node metastasis, and poor prognosis in pharyngolaryngeal cancer patients.
