Purpose: To compare the safety and efficacy of two different techniques for implantation of the XEN Gel Stent, a minimally invasive surgical device for the treatment of refractory glaucoma. Methods: A retrospective chart review of eyes that received ab interno or ab externo XEN Gel Stent placement from February 2017 to October 2019 was conducted. A single surgeon (NMR) performed all operations. Eyes that received the XEN implant concomitant with a glaucoma drainage device insertion or that were lost to 6-month follow-up were excluded. Intraocular pressure (IOP) change, change in glaucoma medications, frequency of slit lamp revision procedures, and frequency of secondary glaucoma surgeries were the primary outcomes compared between groups. Results: Fifty eyes that underwent ab interno placement and 30 eyes that underwent ab externo placement were studied. The ab interno cohort demonstrated a mean IOP reduction of 8.4 ± 1.7 mmHg (28.6% decrease) by 12 months, compared to a mean reduction of 12.8 ± 3.0 mmHg (40.1% decrease) in the ab externo group (p = 0.208). Mean reduction in medication use was 1.81 ± 0.29 medications in the ab interno group and 1.86 ± 0.37 in the ab externo group (p = 0.913). By 12 months, 58% of ab interno eyes had required 5-fluorouracil injection compared to 36.7% of ab externos (p = 0.105). Bleb needling was applied to 42% and 26.7% of the eyes, respectively (p = 0.231). A second glaucoma surgery was necessary for 20% of the ab interno cohort and 10% of the ab externo cohort (p = 0.351). Conclusion: There were no differences in outcomes between ab interno and ab externo placement of the XEN Gel Stent. Both approaches are safe and effective for lowering IOP.
Background The influence of social media among adolescent peer groups can be a powerful change agent. Objective Our scoping review aimed to elucidate the ways in which social media use among adolescent peers influences eating behaviors. Methods A scoping review of the literature of articles published from journal inception to 2019 was performed by searching PubMed (ie, MEDLINE), Embase, CINAHL, PsycINFO, Web of Science, and other databases. The review was conducted in three steps: (1) identification of the research question and clarification of criteria using the population, intervention, comparison, and outcome (PICO) framework; (2) selection of articles from the literature using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines; and (3) charting and summarizing information from selected articles. PubMed’s Medical Subject Headings (MeSH) and Embase’s Emtree subject headings were reviewed along with specific keywords to construct a comprehensive search strategy. Subject headings and keywords were based on adolescent age groups, social media platforms, and eating behaviors. After screening 1387 peer-reviewed articles, 37 articles were assessed for eligibility. Participant age, gender, study location, social media channels utilized, user volume, and content themes related to findings were extracted from the articles. Results Six articles met the final inclusion criteria. A final sample size of 1225 adolescents (aged 10 to 19 years) from the United States, the United Kingdom, Sweden, Norway, Denmark, Portugal, Brazil, and Australia were included in controlled and qualitative studies. Instagram and Facebook were among the most popular social media platforms that influenced healthful eating behaviors (ie, fruit and vegetable intake) as well as unhealthful eating behaviors related to fast food advertising. Online forums served as accessible channels for eating disorder relapse prevention among youth. Social media influence converged around four central themes: (1) visual appeal, (2) content dissemination, (3) socialized digital connections, and (4) adolescent marketer influencers. Conclusions Adolescent peer influence in social media environments spans the spectrum of healthy eating (ie, pathological) to eating disorders (ie, nonpathological). Strategic network-driven approaches should be considered for engaging adolescents in the promotion of positive dietary behaviors.
Purpose To quantify features of musculoskeletal (MSK) complaints among US ophthalmologists and analyze factors related to symptom severity. Methods Cornea, glaucoma, retina, and comprehensive practitioners were invited to complete a web-based survey via email. Data on demographics, practice and procedural volumes, wellness activities, job stress, MSK health, the Total Disability Index (TDI), and ergonomics were collected. Significance testing was performed to evaluate factors related to TDI score. Results Of the 245 ophthalmologists contacted, 58.8% (n = 144) responded at least in part to the survey. Pain episodes were reported in 81.4% (n = 83) of 102 respondents, with 48.1% (n = 49) experiencing daily or weekly attacks. The neck, low back, and shoulders were commonly affected, yet only 57.1% (n=20) of those with shoulder pain reported a corresponding diagnosis. The mean TDI score was 6.2 ± 7.3%, indicating minimal disability related to the spine. Demographics, volume metrics, and wellness hours were each not significantly associated with TDI score (p > 0.05). Higher job stress ratings were reported by those who experienced more frequent pain attacks (p = 0.02) and those with higher TDI scores (p = 0.001). Greater difficulty with clinic, laser, and surgery job tasks was observed in respondents with higher TDI scores (p < 0.001, p = 0.005, and p < 0.001) and more bodily pain locations (p = 0.002, p = 0.002, and p = 0.001). Respondents who pursued practice modifications (p = 0.03) and treatments (p = 0.01) to reduce or prevent pain had higher mean TDI scores, and 94.2% of respondents (n = 97) were interested in learning more about ergonomics. Conclusion Mild MSK complaints were highly prevalent among the surveyed ophthalmologists, and a similar trend could be expected for other US ophthalmologists. Greater frequency and severity of pain may contribute to physician burnout. There may be underdiagnosis of MSK pathology yet also high demand for ergonomic strategies and MSK treatments, suggesting a need for practical solutions.
BACKGROUND The impact of social media among adolescent peer groups can be a powerful change agent. OBJECTIVE Our scoping review aimed to elucidate the ways in which social media use among adolescent peers influences eating behaviors. METHODS A scoping review of the literature from inception to 2019 was performed using PubMed/Medline, Embase, Food Science & Technology Abstracts (FSTA), INSPEC, Cumulative Index to Nursing & Allied Health (CINAHL), PsycINFO, ERIC, Google Scholar and Web of Science databases. The review was conducted in three steps: 1) identification of the research question and clarification of criteria using the PICO framework, 2) selection of the literature using PRISMA guidelines, and 3) charting and summarizing information from selected articles. PubMed’s Medical subject headings (MeSH) and Embase’s Emtree subject headings were reviewed along with specific keywords to construct a comprehensive search strategy. Subject headings and keywords were based on adolescent age groups, social media platforms, and eating behaviors. After screening 1382 peer-reviewed articles, 32 articles were assessed for eligibility. Participant age, gender, study location, social media channel(s) utilized, user volume and content themes related to findings were extracted. RESULTS Six articles fit the final inclusion criteria. A final sample of 1,225 adolescents (ages 10-19) from the United States, England, Sweden, Norway, Denmark, Portugal, Brazil and Australia were included in controlled studies. Instagram and Facebook were among the most popular social media platforms that influenced healthful eating behaviors (i.e., fruit and vegetable intake) as well as unhealthful eating behaviors related to fast food advertising. Online forums and blogs served as accessible channels for eating disorder relapse prevention among youth. Social media influence converged around four central themes: 1. Visual appeal, 2. Content dissemination, 3. Socialized digital connections and 4. Adolescent “marketer” influencers. CONCLUSIONS Adolescent peer influence in social media environments spans the spectrum of healthy eating (non-pathological) to eating disorders (pathological). Strategic network-driven approaches should be considered for engaging adolescents in promotion of positive dietary behaviors.
