Electronic Cigarette Marketing Online: a Multi-Site,Multi-Product Comparison

Background

Electronic cigarette awareness and use has been increasing rapidly. E-cigarette brands have utilized social networking sites to promote their products, as the growth of the e-cigarette industry has paralleled that of Web 2.0. These online platforms are cost-effective and have unique technological features and user demographics that can be attractive for selective marketing. The popularity of multiple sites also poses a risk of exposure to social networks where e-cigarette brands might not have a presence.

Objective

To examine the marketing strategies of leading e-cigarette brands on multiple social networking sites, and to identify how affordances of the digital media are used to their advantage. Secondary analyses include determining if any brands are benefitting from site demographics, and exploring cross-site diffusion of marketing content through multi-site users.

Methods

We collected data from two e-cigarette brands from four social networking sites over approximately 2.5 years. Content analysis is used to search for themes, population targeting, marketing strategies, and cross-site spread of messages.

Results

Twitter appeared to be the most frequently used social networking site for interacting directly with product users. Facebook supported informational broadcasts, such as announcements regarding political legislation. E-cigarette brands also differed in their approaches to their users, from informal conversations to direct product marketing.

Conclusions

E-cigarette makers use different strategies to market their product and engage their users. There was no evidence of direct targeting of vulnerable populations, but the affordances of the different sites are exploited to best broadcast context-specific messages. We developed a viable method to study cross-site diffusion, although additional refinement is needed to account for how different types of digital media are used.     

Comparison of immediate complete denture, tooth and implant-supported overdenture on vertical dimension and muscle activity

PURPOSE

To compare the changes in the occlusal vertical dimension, activity of masseter muscles and biting force after insertion of immediate denture constructed with conventional, tooth-supported and Implant-supported immediate mandibular complete denture.

MATERIALS AND METHODS

Patients were selected and treatment was carried out with all the three different concepts i.e, immediate denture constructed with conventional (Group A), tooth-supported (Group B) and Implant-supported (Group C) immediate mandibular complete dentures. Parameters of evaluation and comparison were occlusal vertical dimension measured by radiograph (at three different time intervals), Masseter muscle electromyographic (EMG) measurement by EMG analysis (at three different positions of jaws) and bite force measured by force transducer (at two different time intervals). The obtained data were statistically analyzed by using ANOVA-F test at 5% level of significance. If the F test was significant, Least Significant Difference test was performed to test further significant differences between variables.

RESULTS

Comparison between mean differences in occlusal vertical dimension for tested groups showed that it was only statistically significant at 1 year after immediate dentures insertion. Comparison between mean differences in wavelet packet coefficients of the electromyographic signals of masseter muscles for tested groups was not significant at rest position, but significant at initial contact position and maximum voluntary clench position. Comparison between mean differences in maximum biting force for tested groups was not statistically significant at 5% level of significance.

CONCLUSION

Immediate complete overdentures whether tooth or implant supported prosthesis is recommended than totally mucosal supported prosthesis.     

Should maximal urethral closure pressure be performed before midurethral sling surgery for stress incontinence? A time to revisit

Introduction and hypothesis

Maximum urethral closure pressure (MUCP) provides an objective assessment of urethral integrity, but its role in predicting outcome after midurethral sling (MUS) placement is debatable and current practice in the UK is variable. The study was carried out to determine if lower preoperative MUCP is associated with poor outcome following MUS.

Method

The study was a retrospective review of the British Society of Urogynaecology (BSUG) database and urodynamics (UDS) data. Patients who reported outcome as “no improvement”, “worse” or “much worse” on the Patient Global Impression of Improvement (PGII) scale were identified as having a poor outcome. Patients who reported “a little improvement”, “improved” and “very much improved” on the PGII were thought to have a good outcome. The preoperative demographics, UDS findings and quality of life (International Consultation of Incontinence questionnaires [ICIQ-SF]) data of the two groups were compared.

Result

A total of 236 women were identified for the study. Of these, 24 women (10.2 %) had a poor outcome. Of the remaining women reporting a good outcome, 50 cases were randomly selected. All urodynamic parameters, including mean functional urethral length (FUL), bladder capacity, and Qmax, were similar, except for mean MUCP 37.05 cm H₂O, which was significantly lower in group 1 (poor outcome 37.05 cm H₂O) compared with a mean MUCP of 50.6 cm H₂O in group 2 (good outcome; p?=?0.005).

Conclusion

We conclude that failure following MUS is associated with preoperatively lower MUCP, which can be used as a predictor of failure.

     

Community-based prevention of hepatitis-B-related liver cancer: Australian insights

Problem

Although most primary hepatocellular cancers (HCCs) are attributable to chronic viral hepatitis and largely preventable, such cancers remain a leading cause of cancer-related mortality wherever chronic hepatitis B is endemic.

Approach

Many HCCs could be prevented by increasing awareness and knowledge of hepatitis B, optimizing the monitoring of chronic hepatitis B and using antiviral treatments – but there are gaps in the implementation of such strategies.

Local setting

The “B Positive” programme, based in Sydney, Australia, is designed to improve hepatitis-B-related health outcomes among immigrants from countries with endemic hepatitis B. The programme offers information about disease screening, vaccination and treatment options, as well as optimized access to care.

Relevant changes

The B Positive programme has been informed by economic modelling. The programme offers culturally tailored education on chronic hepatitis B to target communities and their health practitioners and regular follow-up through a population-based registry of cases.

Lessons learnt

As the costs of screening for chronic hepatitis B and follow-up are relatively low and less than one in every four cases may require antiviral drugs, optimizing access to treatment seems an appropriate and cost-effective management option. The identification and accurate staging of cases and the judicious use of antiviral medications are predicated upon an informed and educated health workforce. As establishing community trust is a lengthy process, delaying the implementation of programmes against chronic hepatitis B until antiviral drugs become cheaper is unwarranted.     

The personal impact of pelvic floor symptoms and their relationship to age

Introduction and hypothesis

The aim was to evaluate the relationship between age and the impact of pelvic floor disorders (PFD) using a multi-dimensional pelvic floor questionnaire

Methods

Questionnaire data on 4,311 women attending urogynaecology clinics with PFD were stratified by age into four groups: ≤35, 36–50, 51–65 and >65 years. The symptom frequency (ranging from 0 to 100) was divided in to mild (0–33), moderate (34–67), and severe (68–100) symptoms. Impact scores for equivalent levels of symptom frequency (mild, moderate and severe symptoms) were compared in women of different ages.

Results

Overall, bowel continence was associated with the greatest bother and constipation the least. Older women were significantly less bothered by mild to moderate urinary, bowel and vaginal symptoms (except IBS and vaginal capacity) than younger women. There was no difference in the impact of severe symptoms in different ages. In contrast, for sexual symptoms, there was a significant difference in the impact in older women for all grades of severity.

Conclusions

Women’s views and attitudes towards symptoms are variable and age is a significant factor. In women attending urogynaecology clinics with pelvic floor symptoms the impact of most symptoms (particularly sexual dysfunction) become less bothersome with age.     

Periodontal Status and High‐Sensitivity C‐Reactive Protein Levels in Polycystic Ovary Syndrome With and Without Medical Treatment

Background: Recently, some studies have revealed the effect of polycystic ovary syndrome (PCOS) on gingival inflammation. This cross‐sectional study attempts to assess the periodontal status and systemic inflammation of women receiving medical treatment for PCOS and women newly diagnosed with PCOS. Methods: A total of 126 participants comprising 41 newly diagnosed patients with PCOS (PCOS‐N), 45 patients with PCOS on medical treatment (PCOS‐MT), and 40 systemically healthy controls (control group [CG]) were examined. Periodontal parameters, anthropometric parameters, and serum levels of high‐sensitivity C‐reactive protein (hsCRP) were recorded. Results: Women with newly diagnosed PCOS had increased sites with bleeding on probing (BOP), probing depth, clinical attachment level (CAL), waist circumference (WC), hsCRP, and prevalence of periodontitis compared with control and PCOS‐MT groups (P ≤0.05). On partial correlation analysis after controlling for confounders, BOP and CAL correlated positively and significantly with hsCRP (P = 0.01 and P = 0.005). Multivariate linear regression analysis revealed that BOP and CAL (dependent variable) (P = 0.009/R² = 0.05 and P = 0.005/R² = 0.07, respectively) had significant association with hsCRP. Furthermore, hsCRP, when considered as outcome, also exhibited association with CAL and WC (P = 0.002/R² = 0.07 and P = 0.04/R² = 0.106). Logistic regression analysis demonstrated that the PCOS‐N group had 2.88 times increased likelihood of having moderate periodontitis (adjusted odds ratio 2.88, 95% confidence interval 1.18 to 6.98). Conclusions: Women with newly diagnosed PCOS may have increased prevalence and likelihood for periodontitis, with higher measures of periodontal inflammation and breakdown than those on medical treatment for PCOS and systemically healthy females. Furthermore, periodontal breakdown might depend on systemic inflammation and vice versa.     

Direct determination of metallic impurities in graphite by EDXRF

Energy dispersive X-ray fluorescence (EDXRF) methods have been developed for the direct determination of 14 trace metallic impurities in graphite powder without any need for sample dissolution. Using synthetic standards, calibration curves were established for different elements after optimizing the spectrometer parameters. Two synthetic samples were analyzed to evaluate the performance of the developed analytical methods. The estimates for most of the analytes were in good agreement with the added amounts. Three graphite powder samples were analyzed by the present method as well as by D.C. arc emission spectrometric technique for comparison and the agreement between the analyte values determined, using both methods was good. Samples in pellet form were analyzed using a separate calibration with standards in pellet form. The present method is rapid, as it alleviates the need for any chemical treatment and gives good precision.     

Utility of a smartphone assisted direct ophthalmoscope camera for a general practitioner in screening of diabetic retinopathy at a primary health care center

Purpose:To assess the use of smartphone-based direct ophthalmoscope photography for screening of diabetic retinopathy (DR) in known diabetic patients walking into a general practitioner''s clinic and referring them to a vitreoretinal specialist for further evaluation and management if required.Methodos:The study included 94 eyes of 47 walk-in patients in a general practitioner''s OPD who were known to have type 2 diabetes mellitus and were already on treatment for the same.Results:The study included 47 patients with diabetes with a mean age of 56.2 ± 9.4 years. The Cohen''s kappa values revealed that the diagnosis related to the DR status made using a camera was in substantial agreement with the clinical diagnosis (Kappa value: 0.770). The Cohen''s kappa values revealed that the diagnosis related to the DME made using a camera was in moderate agreement with the clinical diagnosis (Kappa value: 0.410). The agreement between the findings of the camera and clinical diagnosis was statistically significant (P < 0.05).Conclusion:Direct ophthalmoscope-based smartphone imaging can be a useful tool in the OPD of a general practitioner. These images can be assessed for retinopathy, and patients can be referred to a vitreoretinal specialist for further evaluation and management if needed. Hence, the burden of vision loss due to complications of DR in the rural sector can be abridged.     

The All India Ophthalmological Society - Academic and Research Committee pan-India diabetic retinopathy project “Fixing the missing link”: Prevalence data from West Bengal

Purpose:The aim of this study was to determine the prevalence of diabetic retinopathy (DR) and its risk factors among diabetic patients in rural and urban West Bengal (WB).Methods:Patients were screened in the physician''s clinic by a team of ophthalmologist, optometrist and counsellor. Demographic details, diabetic control, compliance to eye checkup, awareness regarding diabetic blindness, and visual acuity were recorded using a questionnaire. DR was graded both by indirect ophthalmoscopy and fundus photo taken with a portable fundus camera.Results:A total of 1553 subjects were screened over 39 camps across 14 districts of WB over 17 months. The prevalence of DR was 21.51%, with a significant difference between rural (26.55%) and urban (13.89%) areas (P < 0.01). No significant difference with gender was seen (P = 0.99). Presence and grade of DR were related to age, loss of vision, diabetic age, diabetic control, awareness of diabetic blindness and last eye checkup.Conclusion:This study provides the first major prevalence data from WB, and gives valuable insight regarding modifiable risk factors for DR. It is also the first DR study in India to be conducted in the physician''s clinic. The study results emphasise the need to “fix the missing link” between ophthalmologists and treating physicians to win the battle against DR.
