ABSTRACT

Patients and family caregivers tell different stories about their illness and care experiences than their physicians do. Better understanding of the relationships among these narratives could offer insight into intersections and disconnections in patient, caregiver and physician perceptions of illness and care. Such understanding could support enhanced patient-centred care in medical education and practice. Narrative writing is increasingly common among physicians, patients and caregivers and uniquely positioned to reveal matters of concern to these groups. We conducted a scoping review to identify literature in which first-person narratives from more than one group (physicians, patients and/or caregivers) were considered as 'data'. A search strategy involving nine databases located 6337 citations. Two reviewers independently screened titles and abstracts. Full-text screening followed (n=82), along with handsearching of grey literature and bibliographies. Of these, 22 met inclusion criteria. Most pieces analysed narratives by patients and caregivers (n=13), followed by patients, caregivers and physicians (n=7) and patients and physicians (n=2). Only nine pieces compared perspectives among any of these groups. The rest combined narratives for analysis, largely patient and caregiver stories (n=12). Most of the 22 papers used descriptive content analysis to derive themes. Themes of humanity, identity, agency and communication intersect between groups but often manifest in unique ways. What is absent, however, is a more interpretive narrative analysis of structure, orientation and characterisation within these narratives, which may reveal even more than their content. This scoping review offers a cautionary tale of lost potential. Many narratives are gathered and analysed but usually only thematically and rarely comparatively. We call for researchers to explore the potential of comparative analysis and the power of narrative inquiry in the field. Comparative narrative analysis may enrich understanding of how differences between perspectives come to be and what they mean for the experience of illness and care.

ABSTRACT

OBJECTIVE: A critical element in conducting a systematic review is the identification of studies. To date, very little empirical evidence has been reported on whether the presence of a librarian or information professional can contribute to the quality of the final product. The goal of this study was to compare the reporting rigor of the literature searching component of systematic reviews with and without the help of a librarian. METHOD: Systematic reviews published from 2002 to 2011 in the twenty highest impact factor pediatrics journals were collected from MEDLINE. Corresponding authors were contacted via an email survey to determine if a librarian was involved, the role that the librarian played, and functions that the librarian performed. The reviews were scored independently by two reviewers using a fifteen-item checklist. RESULTS: There were 186 reviews that met the inclusion criteria, and 44% of the authors indicated the involvement of a librarian in conducting the systematic review. With the presence of a librarian as coauthor or team member, the mean checklist score was 8.40, compared to 6.61 (p<0.001) for reviews without a librarian. CONCLUSIONS: Findings indicate that having a librarian as a coauthor or team member correlates with a higher score in the literature searching component of systematic reviews.

ABSTRACT

BACKGROUND: Minimally invasive glaucoma surgeries (MIGS) have attracted significant attention, as they have been reported to lower intra-ocular pressure (IOP) and have an excellent safety profile. The iStent is an example of a minimally invasive glaucoma device that has received particular attention due to its early and wide spread utilization. There is a growing body of evidence supporting its use at the time of phacoemulsification to help lower IOP. However, it is still not clear how much of the IOP lowering effect can be attributed to the iStent, the crystalline lens extraction or both when inserted concurrently at the time of phacoemulsification. This has been an important issue in understanding its potential role in the glaucoma management paradigm. PURPOSE: To conduct a systematic review and meta-analysis comparing the IOP lowering effect of iStent insertion at the time of phacoemulsification versus phacoemulsification alone for patients with glaucoma and cataracts. METHODS: A systematic review was conducted utilizing various databases. Studies examining the IOP lowering effect of iStent insertion in combination with phacoemulsification, as well as studies examining the IOP lowering effect of phacoemulsification alone were included. Thirty-seven studies, reporting on 2495 patients, met the inclusion criteria. The percentage reduction in IOP (IOPR%) and mean reduction in topical glaucoma medications after surgery were determined. The standardized mean difference (SMD) was computed as a measure of the treatment effect for continuous outcomes taking into account heterogeneity. Fixed-effect and random-effect models were applied. RESULTS: A 4% IOP reduction (IOPR%) from baseline occurred following phacoemulsification as a solo procedure compared to 9% following an iStent implant with phacoemulsification, and 27% following 2 iStents implants with phacoemulsification. Compared with cataract extraction alone, iStent with phacoemulsification resulted in significant reduction in the post-operative IOP (IOPR%) (SMD = -0.46, 95% CI: [-0.87, -0.06]). A weighted mean reduction in the number of glaucoma medications per patient was 1.01 following phacoemulsification alone compared to 1.33 after one iStent implant with phacoemulsification, and 1.1 after 2 iStent implants with phacoemulsification. Compared to cataract extraction alone, iStent with cataract extraction showed a significant decrease in the number of glaucoma medications (SMD = -0.65, 95% CI: [-1.18, -0.12]). Funnel plots suggested the absence of publication bias. CONCLUSION: Both iStent implantation with concurrent phacoemulsification and phacoemulsification alone result in a significant decrease in IOP and topical glaucoma medications. In terms of both reductions, iStent with phacoemulsification significantly outperforms phacoemulsification alone.

ABSTRACT

BACKGROUND: Glaucoma is a leading cause of irreversible blindness. It is firmly entrenched in the traditional treatment paradigm to start with pharmacotherapy. However, pharmacotherapy is not benign and has been well documented to have a number of significant challenges. Minimally invasive glaucoma surgery (MIGS) that targets the outflow pathway with minimal to no scleral dissection has resulted in the need to reconsider the glaucoma treatment paradigm. PURPOSE: To perform a systematic review and meta-analysis to evaluate and quantify the effect on post-operative intraocular pressure (IOP) and number of topical glaucoma medications, in patients receiving the iStent MIGS device as the solo procedure without concurrent cataract surgery. METHODS: A systematic review was conducted by searching various databases between January 1, 2000, and June 30, 2014. Studies reporting up to a maximum follow-up period of 24 months were retrieved and screened using the EPPI-Reviewer 4 gateway. Percentage reduction in IOP (IOPR%), and mean reduction in topical glaucoma medications after surgery were computed. Meta-analysis was performed using STATA v. 13.0. The standardized mean difference (SMD) was calculated as the effect size for continuous scale outcomes. Heterogeneity was determined using the I2 statistics, Z-value, and χ2 statistics. Fixed-effect and random-effect models were developed based on heterogeneity. Sub-group analysis was performed based on the number of iStents implanted and the follow-up period. The outcome measures were changes in the IOP and number of glaucoma medications. RESULTS: The search strategy identified 105 records from published literature and 9 records from the grey literature. Five studies with 248 subjects were included for quantitative synthesis. A 22% IOP reduction (IOPR%) from baseline occurred at 18-months after one iStent implant, 30% at 6-months after two iStents implantations, and 40% at 6-months after implantation of three iStents. A mean reduction of 1.2 bottles per patient of topical glaucoma medications occurred at 18-months after one iStent implant, 1.45 bottles per patient at 6-months after two iStents, and one bottle of medication per patient was reduced at 6-months following placement of three iStents implants. Meta-analysis results showed a significant reduction in the IOP after one iStent (SMD = -1.68, 95% CI: [-2.7, -0.61]), two iStents (SMD = -1.88, 95% CI: [-2.2, -1.56]), and three iStents (SMD = -2, 95% CI: [-2.62, -1.38]) implantation. Results showed a significant drop in the topical glaucoma medications after one iStent (SMD = -2.11, CI: [-3.95, -0.27]), two iStent (SMD = -1.88, CI: [-2.20, -1.56]), and three iStents (SMD = -2.00, CI: [-2.62, -1.38]) implantation. The maximum reduction in IOP occurred at 12-months (SMD = -2.21, CI: [-2.53, -1.88]) and a significant reduction in post-operative topical glaucoma medications occurred even after 18-months of iStent implantation (SMD = -0.71, CI: [-1.15, -0.26]). CONCLUSION: iStent implantation as a solo procedure without concurrent cataract extraction does lower IOP, and reduces the dependency on glaucoma medications. This effect seems to last at least 18 months.

ABSTRACT

OBJECTIVE: To characterize the association between commonly used anti-epileptic drugs (AEDs) and plasma lipid levels in patients with epilepsy. METHODS: We sought observational studies that reported association between commonly used AEDs and plasma lipid levels in patients. The primary outcome was low-density lipoprotein (LDL) cholesterol. High-density lipoprotein (HDL), total cholesterol and triglyceride were secondary outcomes. The control group included healthy controls, pre-treatment patients or patients treated with other AEDs. We conducted a systematic search of major bibliographic databases and review of reference lists of primary articles and reviews. Primary comparisons of interest were: AED monotherapy vs. no AED use, monotherapy with one AED vs. other AED, and AED polytherapy vs. no AED use. RESULTS: 31 studies in 4126 people were identified. Carbamazepine, phenytoin and valproic acid were the most commonly studied drugs and were also implicated in causing considerable changes in plasma lipid levels in treated patients. There was an increase in LDL and total cholesterol levels with use of these three drugs; however, carbamazepine and phenytoin were also associated with higher levels of HDL. We could not identify one particular AED which was worse than the other in head-to-head comparison. We were unable to identify a particular polytherapy regimen that was worse than others. CONCLUSION: We found evidence to suggest that some AEDs may negatively alter lipids levels in patients with epilepsy. Both treating physicians and people with epilepsy need to be vigilant in managing their vascular risk factors to avoid vascular disease.

ABSTRACT

OBJECTIVES: Current recommendations for safe and effective dental management are less than optimal for some medical conditions because of limited evidence, conflicting conclusions, or both. This review (1) compiled and evaluated dental management recommendations for select medical conditions; (2) summarized recommendations and their assigned levels of evidence; (3) identified areas of conflict, ambiguity, or both; and (4) identified issues that warrant future research, enhanced consensus statements, or both. STUDY DESIGN: Systematic literature searches were performed for guideline publications, systematic and narrative reviews, and opinion documents containing recommendations for (1) medication-related osteonecrosis of the jaw (MRONJ); (2) cardiovascular diseases (CVDs); (3) prosthetic joints (PJs); and (4) systemic steroid therapy (SST). RESULTS: The search yielded the following numbers of publications that met the inclusion criteria: MRONJ - 116; CVDs - 54; prosthetic joints - 39; and systemic steroids - 12. CONCLUSIONS: Very few of the compiled recommendations were assigned or linked to levels of evidence by their authors. Key conclusions include the following: MRONJ-expert recommendations trend toward proceeding with dental treatment with little to no modification in osteoporotic patients on bisphosphonates; CVDs-current recommendations are primarily directed to general surgery and applied to dentistry; PJs-routine antibiotic prophylaxis is not indicated for dental treatment; and SST-steroid supplementation is not indicated for most patients undergoing dental procedures under local anesthesia.

ABSTRACT

BACKGROUND: Glaucoma is the leading cause of irreversible visual impairment in the world affecting 60.5 million people worldwide in 2010, which is expected to increase to approximately 79.6 million by 2020. Therefore, glaucoma screening is important to detect, diagnose, and treat patients at the earlier stages to prevent disease progression and vision loss. Teleglaucoma uses stereoscopic digital imaging to take ocular images, which are transmitted electronically to an ocular specialist. The purpose is to synthesize literature to evaluate teleglaucoma, its diagnostic accuracy, healthcare system benefits, and cost-effectiveness. METHODS: A systematic search was conducted to help locate published and unpublished studies. Studies which evaluate teleglaucoma as a screening device for glaucoma were included. A meta-analysis was conducted to provide estimates of diagnostic accuracy, diagnostic odds ratio, and the relative percentage of glaucoma cases detected. The improvements to healthcare service quality and cost data were assessed. RESULTS: Of 11237 studies reviewed, 45 were included. Our results indicated that, teleglaucoma is more specific and less sensitive than in-person examination. The pooled estimates of sensitivity was 0.832 [95% CI 0.770, 0.881] and specificity was 0.790 [95% CI 0.668, 0.876]. The relative odds of a positive screen test in glaucoma cases are 18.7 times more likely than a negative screen test in a non-glaucoma cases. Additionally, the mean cost for every case of glaucoma detected was $1098.67 US and of teleglaucoma per patient screened was $922.77 US. CONCLUSION: Teleglaucoma can accurately discriminate between screen test results with greater odds for positive cases. It detects more cases of glaucoma than in-person examination. Both patients and the healthcare systems benefit from early detection, reduction in wait and travel times, increased specialist referral rates, and cost savings. Teleglaucoma is an effective screening tool for glaucoma specifically for remote and under-services communities.

ABSTRACT

OBJECTIVES: The aim of this review was to assess the effect of different adhesive systems and tooth preparation on the retention of tooth-colored restorative materials placed in non-carious cervical lesions (NCCLs). METHODS: Randomized clinical trials with a minimum of 3 years of follow-up that evaluated the effectiveness of tooth-colored materials, adhesive systems, and preparation techniques for the restoration of NCCLs were selected. The Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE (OVID), the Latin American and Caribbean Health Sciences Literature database (LILACS), and Medline (OVID) electronic databases were searched from 1990 to 2013. RESULTS: Twenty-seven randomized clinical trials were included and reviewed. Meta-analysis was used to determine the relative risk of loss of tooth-colored NCCL restorations between different categories of adhesive systems. The effect of tooth preparation could not be similarly analyzed. CONCLUSION: The current best evidence indicates that a glass ionomer cement has a significantly lower risk of loss of a NCCL restoration compared to either a three-step etch-and-rinse or a two-step etch-and-rinse adhesive system; a three-step etch-and-rinse adhesive system has a significantly lower risk of loss of a NCCL restoration compared to a two-step etch-and-rinse adhesive system. No significant difference could be observed in the risk of loss of a tooth-colored NCCL restoration between a three-step etch-and-rinse adhesive system and either a two-step self-etch or a one-step self-etch adhesive system.

ABSTRACT

OBJECTIVE: To synthesise the association of shift work with major vascular events as reported in the literature. DATA SOURCES: Systematic searches of major bibliographic databases, contact with experts in the field, and review of reference lists of primary articles, review papers, and guidelines. STUDY SELECTION: Observational studies that reported risk ratios for vascular morbidity, vascular mortality, or all cause mortality in relation to shift work were included; control groups could be non-shift ("day") workers or the general population. DATA EXTRACTION: Study quality was assessed with the Downs and Black scale for observational studies. The three primary outcomes were myocardial infarction, ischaemic stroke, and any coronary event. Heterogeneity was measured with the I(2) statistic and computed random effects models. RESULTS: 34 studies in 2,011,935 people were identified. Shift work was associated with myocardial infarction (risk ratio 1.23, 95% confidence interval 1.15 to 1.31; I(2)=0) and ischaemic stroke (1.05, 1.01 to 1.09; I(2)=0). Coronary events were also increased (risk ratio 1.24, 1.10 to 1.39), albeit with significant heterogeneity across studies (I(2)=85%). Pooled risk ratios were significant for both unadjusted analyses and analyses adjusted for risk factors. All shift work schedules with the exception of evening shifts were associated with a statistically higher risk of coronary events. Shift work was not associated with increased rates of mortality (whether vascular cause specific or overall). Presence or absence of adjustment for smoking and socioeconomic status was not a source of heterogeneity in the primary studies. 6598 myocardial infarctions, 17,359 coronary events, and 1854 ischaemic strokes occurred. On the basis of the Canadian prevalence of shift work of 32.8%, the population attributable risks related to shift work were 7.0% for myocardial infarction, 7.3% for all coronary events, and 1.6% for ischaemic stroke. CONCLUSIONS: Shift work is associated with vascular events, which may have implications for public policy and occupational medicine.

ABSTRACT

OBJECTIVE: The purpose of this study was to complete a systematic review and, if possible, a meta-analysis on the effectiveness of systemic and topical nucleoside antiviral agents in the prevention of recurrent herpes labialis (RHL) in immunocompetent subjects. STUDY DESIGN: Multiple comprehensive electronic and manual literature searches without language restrictions identified the studies to be included. Quality assessment and data synthesis methods followed those described in the Cochrane guidelines. RESULTS: Of 2,683 papers reviewed, 10 met the inclusion criteria. Oral acyclovir (800-1,600 mg daily) and valacyclovir (500 mg daily for 4 months) were shown to be effective in the prevention of RHL when taken prior to the appearance of any symptoms or exposure to triggers. Of the 10 papers reviewed, only 1 was determined to have a low risk of bias. CONCLUSIONS: This review found support for the use of systemic acyclovir and valacyclovir for the prevention of RHL.
