e., less placebo response) in depression than those who did not receive the PCRS (n = 67). The magnitude of this effect was medium (Cohen’s d = 0.40) and was not significantly impacted by diagnostic status. The number of adverse events (i.e., nocebo effect) was also lower in the PCRS group, particularly in the first week of the study. These findings suggest that briefly educating participants about placebo response factors can help mitigate the large placebo response rates that are increasingly seen in failed CNS drug development programs.Hyaluronic acid (HA) is a highly abundant component in the extracellular matrix (ECM) and a fundamental element to the architecture and the physiology of the central nervous system (CNS). Often, HA degradation occurs when an overreactive inflammatory response, derived from tissue trauma or neurodegenerative diseases such as Alzheimer’s, causes the ECM in the CNS to be remodeled. Herein, we studied the effects of HA content as a key regulator of human astrocyte (HAf) reactivity using multicomponent interpenetrating polymer networks (mIPNs) comprised of Collagen I, HA and poly(ethylene glycol) diacrylate. The selected platform facilities the modulation of HA levels independently of matrix rigidity. Total astrocytic processes length, number of endpoints, the expression of the quiescent markers Aldehyde Dehydrogenase 1 Family Member L1 (ALDH1L1) and Glutamate Aspartate Transporter (GLAST); the reactive markers Glial Fibrillary Acidic Protein (GFAP) and S100 Calcium-Binding Protein β (S100β); and the inflammatory markers Inducible Nitric Oxide Synthase (iNOS), Interleukin 1β (IL-1β) and Tumor Necrosis Factor Alpha (TNFα), were assessed. Cumulatively, our results demonstrated that the decrease in HA concentration elicited a reduction in the total length of astrocytic processes and an increase in the expression of HAf reactive and inflammatory markers.Introduction Oral health-related quality of life is a reflection of general health and wellbeing; related problems stand as major public health issues.Aim To investigate the potential association between dental caries and quality of life (QoL) among children aged 5-6 years old.Materials and methods Oral examination of 310 children admitted to a paediatric dentistry clinic was performed by using the International Caries Detection and Assessment System II (ICDAS-II) and the QoL was assessed using the Early Childhood Oral Health Impact Scale. PARP activity A nested case-control study was conducted with all 104 QoL-unaffected children as the controls and a random sample of 104 QoL-affected children as the cases. Relative risk (RR) and its 95% confidence interval (CI) values were calculated to interpret potential associations.Results Gender distribution was similar by case controls (52.9% vs 51.0% were females, respectively). Early childhood caries (ECC) was detected in 78.8% of cases and 19.2% of controls. In binary analysis of the QoL (with a cutpoint of 2), low parental education, having a sibling, dental visit history for complaints and irregular/no toothbrushing were detected as significant predictors of poor QoL (p value less then 0.001). The RR of negative impact on QoL was fourfold (95% CI 2.64-5.69) among children having ECC, revealing a significant upward trend of impaired QoL with increasing ICDAS-II scores (t = 13.323; p value less then 0.001).Conclusion All patients should be evaluated thoroughly for social and psychological problems, besides functional and aesthetic in dental visits.Aims This exploratory study is the first in a series of two examining the working conditions of the community and public dental services in the UK to provide insight, context and understanding on their current status.Methods Secondary analysis of census data was supplemented by qualitative analysis of interview data from community and public dental service dentists. Demographic and working conditions data were examined and interview participants discussed their role, service and patients, potential service improvements and how they saw the services developing.Results Overall, dentists were satisfied with their role but did not feel secure in their job and worked more hours than they were contracted to. Interviews identified three key themes 1) personal – aspects affecting the interviewee on a personal level; 2) patients – aspects affecting patients; and 3) service – aspects relating to the service. Services had changed and were seen, in part, to have become more efficient, but some clinicians thought the focus had moved away from patients.Conclusions Overall, clinicians enjoyed their role, but while services were seen to provide good patient care, dentists felt under pressure. Changes to general dental practice, management practices and increased funding were believed likely to improve the services.Aim An ex vivo study was performed to assess (gold standard [GS] Nyvad criteria) sensitivities (SEs) and specificities (SPs) of Soprolife (fluorescence) and Calcivis (bioluminescence) – indicated, by the manufacturers, for activity assessment of coronal carious lesions (AACCL). We also calculated the positive and negative predictive values, positive and negative log-likelihoods, inter-examiner and intra-examiner variations, and concordance rates (CRs) of both devices compared to GS and to each other.Materials and methods One hundred and twenty-one extracted posterior teeth were included. Within 48 hours after extraction, ICDAS and Nyvad scores were determined and occlusal photographs (Soprolife and Calcivis captures) were taken. Three examiners were asked to score, independently, twice (T0; T0 + 15 days), the caries activity status (active/inactive) for each image.Results Both devices showed modest SEs and SPs. The only statistically significant differences between devices were for SE (p = 0.04) in favour of Soprolife (all ICDAS scores combined) and for SP (p = 0.03) in favour of Calcivis (ICDAS 3, 4). There were higher CRs for Soprolife than for Calcivis (compared to GS). Intra- and inter-examiner variations were 76-86.8% and 71.9-85.1% for Soprolife, and 79.3-89.3% and 72.7-86.8% for Calcivis, respectively.Conclusion In light of the results, it seems difficult to confirm the validation of Soprolife and Calcivis for AACCL.
