Background: Novel approaches to engage community smokers in smoking cessation are needed as smokers typically lack motivation to quit or use evidence-based tobacco dependence treatment. Mobile instant messaging apps (e.g., WhatsApp, Facebook Messenger) are widely used but under-studied as a mobile health modality for delivering smoking cessation support. This paper presents the rationale and study design of a trial which aims to evaluate the effectiveness of a chat-based intervention using mobile instant messaging combined with brief interventions for community smokers., Methods: This is a two-arm, parallel, accessor-blinded, pragmatic cluster-randomized controlled trial on an estimated 1172 daily cigarette smokers aged ≥18 years proactively recruited from 68 community sites (cluster) throughout Hong Kong. Subjects in intervention group received three months of chat-based, instant messaging support guided by acceptance and commitment therapy and other behavioural change techniques, integrated with brief advice and active referral to a smoking cessation service using the AWARD (Ask, Warn, Advise, Refer, Do-it-again) intervention model. Control group received brief advice to quit plus a self-help booklet at baseline. Outcomes were assessed at 1-, 2-, 3- and 6-month after baseline. The primary outcome is abstinence validated by exhaled carbon monoxide (<4 ppm) and salivary cotinine (<10 ng/mL) at 6-month after baseline. Primary analyses will be based on intention-to-treat., Comments: This is the first trial examining the effectiveness of a chat-based cessation support programme combined with brief interventions in promoting abstinence. The intervention model can be adapted for other behavioural change treatments and more advanced digital smoking cessation intervention., (Copyright © 2018 Elsevier Inc. All rights reserved.)

This study assessed the impact of an information pamphlet on acceptance of human papillomavirus (HPV) vaccine in Chinese women. The pamphlet increased the self-perceived knowledge on cervical cancer and HPV of the study subjects and had a positive influence on women accepting HPV vaccination for their daughters (p < .001).

Objective: Our aim was to determine the distance of the ureter from the cervix and the influence of age and weight on this distance., Study Design: The distance of the ureter from the uterine cervix was determined by evaluating the computed pelvic tomograms from 52 women. Age and body mass index were compared to this distance by means of regression analysis., Results: At the most dorsal reflection of the ureter, the average distance from ureter to cervical margin was 2.3 +/- 0.8 cm (range, 0.1-5.3 cm). There was no relationship to age, but there was a linear relationship between this distance and body mass index (R2 = 0.075; P = .049); thus the ureter was slightly more proximal to the cervical margin in heavier women., Conclusions: In women with apparently normal pelvic anatomy, the average distance between the ureter and cervix is >2 cm. The finding that this distance is <0.5 cm in 12% of the women studied may explain the relatively common occurrence of ureteral injury during hysterectomy. The relationship between body mass index and location is clinically insignificant.
