The present study indicates that, compared to SRP alone, multiple adjunctive applications of a 980-nm diode laser with SRP showed PD improvements only in moderate periodontal pockets (4 to 6 mm).

Background: Cochrane systematic review Plain language Summaries (CSR PLSs should serve as a tool for the evidence translation to non-medical population. However, the evidence of optimal type of numerical presentation in CSR PLSs is still scarce. The aim of this study was to investigate readers' comprehension and preferences for different presentation of findings, including framing and numerical data, in Cochrane systematic review Plain Language Summaries (CSR PLSs). Methods: We conducted a parallel randomized trial and a crossover randomized trial at the School of Medicine and family practice offices in Split, Croatia. The participants were students and consumers. We assessed possible differences in comprehension, measured by four questions on PLS content, of CSR PLSs depending on the positive or negative framing of results (n = 91) (Trial 1) or using percentages or frequencies for the presentation of results (n = 245) (Trial 2). The outcome measures were comprehension of PLS content, perceived effectiveness of the treatment and readiness to use the treatment (all on 1-10 scales). Results: In Trial 1 we found no difference in readers' perception of the effectiveness of the described treatment, desire that the treatment be offered by their family doctor, readiness to use the treatment, or comprehension when CSR PLS results were presented positively or negatively. In Trial 2 we found no difference in CSR PLS comprehension when results were presented as natural frequencies or percentages (BF 10 = 0.62, Bayesian t-test for independent samples). Conclusions: Numerical presentation and framing direction of results appear to have no significant impact on understanding of messages in CSR PLSs.

Background Cochrane, an organization dedicated to the production and dissemination of high-quality evidence on health, endeavors to reach consumers by developing appropriate summary formats of its systematic reviews. However, the optimal type of presentation of evidence to consumers is still unknown. Objective The aim of this study was to investigate consumer preferences for different summary formats of Cochrane systematic reviews (CSRs), using both qualitative and quantitative approaches. Methods Initially, we conducted three focus groups with medical students (n = 7), doctors (n = 4), and patients (n = 9) in 2017 to explore their health information search habits and preferences for CSR summary formats. Based on those findings, we conducted a randomized trial with medical students at the University of Split School of Medicine, Croatia, and with patients from three Dalmatian family practices to determine whether they prefer CSR blogshots (n = 115) or CSR plain language summaries (PLSs; n = 123). Results Participants in the focus groups favored brief and explicit CSR summary formats with fewer numbers. Although we found no difference in participants’ preferences for a specific summary format in the overall sample, subgroup analysis showed that patients preferred blogshots over PLSs in comparison to medical students (P = 0.003, eta squared effect size η2 = 0.04). Conclusion CSR summaries should be produced in a format that meets the expectations and needs of consumers. Use of blogshots as a summary format could enhance the dissemination of CSRs among patients. Trial registration The trial was registered in ClinicalTrials.gov, NCT03542201. Registered on May 31st 2018.

We analysed all journals from two Journal Citation Reports (JCR) categories: ‘Dentistry, Oral Surgery and Medicine’ and ‘Otorhinolaryngology’ published in 2018 for their policies on publishing facial photographs and actual practices of publishing these photographs in articles. We extracted the following data for each journal: JCR category, impact factor, volume, issue, instructions for authors regarding ethical issues, instructions for photograph deidentification, journals’ references to standard research and publishing policies, presence and type of published clinical images, separate informed consent for the publication of patient photograph and methods of deidentification. The sample included 103 journals, which published 568 articles with 1404 clinical images. Around a half of the journals (52%) had a policy on clinical images, however, the only predictor of having a journal policy on clinical images was reference in the policy to International Committee of Medical Journal Editors Recommendations (OR=3.00, 95% CI 1.26 to 7.14, p=0.013). Identifiable patient photographs were found in 13% (79/568) of the articles, constituting 9% (128/1404) of the total sample of images. Only 16% (13/79) of articles publishing recognisable patient facial images included a statement about consent for publication of the image. From the total sample of articles, 34% (27/79) contained deidentified but recognisable patient photographs and only 22% (6/27) of them had a statement about patient consent for photograph publication. The patients’ consent was more likely stated in the article in cases of recognisable facial images (OR=2.81, 95% CI 1.41 to 5.63, p=0.004). Journals publishing clinical research involving the face and neck region need to establish and enforce policies on publishing clinical images.

Periodontitis is a common degenerative disease initiated by the bacteria in subgingival biofilm. The exposure to bacterial biofilm triggers host inflammatory response whose dysregulation is ultimately responsible for the destruction of hard and soft periodontal tissues resulting in tooth loss. To date, significant effort has been invested in the research of the involvement of host cells and inflammatory mediators in regulation of inflammatory response in periodontitis. Syndecans (Sdcs) belong to a four-member family of heparan sulfate proteoglycans (HSPGs). Sdcs are compound molecules comprised of the core protein to which several heparan sulfate (HS) glycosaminoglycan (GAG) chains are attached. The role of Sdcs in pathogenesis of periodontitis is poorly investigated despite the numerous reports from experimental studies about the critical involvement of these factors in modulation of various aspects of inflammatory response, such as the formation of inflammatory mediators gradients, leukocyte recruitment and extracellular matrix remodeling in resolution of inflammation. Most of these functions of Sdcs are HS-related and, thus, dependent upon the structure of HS. This, in turn, is determined by the combinatorial action of enzymes for biosynthesis and modification of HS such as exostosis (EXTs), sulfotransferases (NDSTs), and heparanase 1 (HPSE1). The data presented in this study clearly indicate that some Sdcs display different expression profiles in healthy and diseased periodontal tissue. Additionally, the differences in expression profiles of HS GAG biosynthesis and modification enzymes (EXTs, NDSTs, and HPSE1) in healthy and diseased periodontal tissue imply that changes in HS GAG content and structure might also take place during periodontitis. Most notably, expression profiles of Sdcs, EXTs, NDSTs, and HPSE1 differentially correlate with the presence of inflammatory infiltrate in healthy and diseased periodontal tissue, which might imply that these factors could also be involved in modulation of inflammatory response in periodontitis.
