Prominent e-commerce platforms allow users to write reviews for the available products. User reviews play an important role in creating the perception of the product and impact the sales. Online reviews can be considered as an important source of e-word of mouth (e-WOM) on e-commerce platforms. Various dimensions of e-WOM on product sales have been examined for different products. Broadly, studies have explored the effect of summary statistics of reviews on product sales using data from various e-commerce platforms. Few studies have utilized other review characteristics as length, valence, and content of the reviews. The sequence of reviews has been hardly explored in the literature. This study investigates the impact of sequence of helpful reviews along with other review characteristics as ratings (summary statistics), volume, informativeness, and valence of reviews on product sales. Hence, a holistic approach has been used to explore the role of summary statistics, volume, content and sequence of reviews on product sales with special emphasis on sequence of reviews. Relevant theories such as message persuasion, cognitive overload and belief adjustment model have also been explored during the construction of the model for review data. The proposed model has been validated using the helpful reviews available on Amazon.in website for various products.Version

Effectiveness of pharmacist-led medication review in pain management: systematic review and meta-analysisThe objective of this article was to evaluate the effectiveness of pharmacist-led medication review in chronic pain management. Six electronic databases (Medline, Embase, PsycInfo, CINHAL, CENTRAL, International Pharmaceutical Abstracts) reference lists of retrieved articles and relevant websites were searched for randomized controlled trials published in the English language involving adults with chronic pain. Studies were included if one of the intervention arms had received pharmacist-led medication review independently or as part of a multidisciplinary intervention. Risk of bias was assessed for all the included studies. The search strategy yielded 583 unique articles including 5 randomized controlled trials. Compared with control, meta-analysis showed that participants in the intervention group had: a 0.8-point reduction in pain intensity on a 0 to 10 numerical rating scale at 3 months [95% confidence interval (CI), -1.28 to -0.36] and a 0.7-point reduction (95% CI, -1.19 to -0.20) at 6 months; a 4.84 point (95% CI, -7.38 to -2.29) and -3.82 point (95% CI, -6.49 to -1.14) improvement in physical functioning on a 0- to 68-point function subscale of Western Ontario and McMaster Universities Osteoarthritis Index at 3 and 6 months, respectively; and a significant improvement in patient satisfaction equivalent to a "small to moderate effect." Pharmacist-led medication review reduces pain intensity and improves physical functioning and patient satisfaction. However, the clinical significance of these findings remain uncertain due to small effect size and nature of reported data within clinical trials that limits recommendation of wider clinical role of pharmacist in chronic pain management.

What do we know about brief interventions for physical activity that could be delivered in primary care consultations? A systematic review of reviewsThis systematic review of reviews aims to investigate how brief interventions (BIs) are defined, whether they increase physical activity, which factors influence their effectiveness, who they are effective for, and whether they are feasible and acceptable. We searched CINAHL, Cochrane database of systematic reviews, DARE, HTA database, EMBASE, MEDLINE, PsycINFO, Science Citation Index-Expanded and Social Sciences Citation Index, and Scottish Intercollegiate Guidelines Network from their inception until May 2015 to identify systematic reviews of the effectiveness of BIs aimed at promoting physical activity in adults, reporting a physical activity outcome and at least one BI that could be delivered in a primary care setting. A narrative synthesis was conducted. We identified three specific BI reviews and thirteen general reviews of physical activity interventions that met the inclusion criteria. The BI reviews reported varying definitions of BIs, only one of which specified a maximum duration of 30 min. BIs can increase self-reported physical activity in the short term, but there is insufficient evidence about their long-term impact, their impact on objectively measured physical activity, and about the factors that influence their effectiveness, feasibility and acceptability. Current definitions include BIs that are too long for primary care consultations. Practitioners, commissioners and policy makers should be aware of this when interpreting evidence about BIs, and future research should develop and evaluate very brief interventions (of 5 min or less) that could be delivered in a primary care consultation.
