RESUMO

Type I interferons play a fundamental role in innate host defense against viral infections by eliciting the induction of an antiviral gene program that serves to inhibit viral replication. Activation of type I interferon is regulated by the IRF3 transcription factor, which undergoes phosphorylation-dependent activation by the upstream kinase, TBK1, during viral infection. However, the mechanisms by which TBK1 achieves activation to support signaling to IRF3 remain incompletely understood. Here we identified the E3 ubiquitin ligase, tripartite motif containing 28 (TRIM28), as a positive regulator of type I interferon activation by facilitating TBK1 signaling. Genetic deletion of TRIM28 via CRISPR-Cas9 editing resulted in impaired type I interferon activation upon both RNA and DNA virus challenge, corresponding with increased susceptibility to virus infections in TRIM28 knockout cells. Mechanistically, TRIM28 interacted with TBK1 and mediated the assembly of K63-linked ubiquitin chains onto TBK1, a post-translational modification shown to augment TBK1 signal transmission events. TRIM28 knockout cells further displayed defective TBK1 phosphorylation and complex assembly with IRF3, resulting in impaired IRF3 phosphorylation. Altogether, our data demonstrate TBK1 to be a novel substrate for TRIM28 and identify TRIM28 as an essential regulatory factor in controlling innate antiviral immune responses.

RESUMO

OBJECTIVE: To investigate the impact of various degrees of white spot lesions (WSLs) of maxillary anterior teeth on the aesthetic perception and treatment satisfaction among orthodontic patients, orthodontists and other dental specialists and to evaluate the differences among the three groups. METHODS: A total of 45 orthodontic patients (OP), 45 orthodontists (OR) and 45 other dental specialists (OS) were recruited. Subjective evaluations of perceived aesthetics and treatment satisfaction were performed towards eight digitally generated photographs of maxillary anterior teeth with incremental degrees of WSLs using a numerical visual analogue scale (VAS) from 0 to 100. Data were collected and analysed with descriptive statistics, repeated one-way analysis of variance and multivariable generalized estimating equations. RESULTS: A total of 135 valid questionnaires were collected. Regarding aesthetic scores for WSLs, OP gave more positive scores than OR and OS (p < .05) towards excessive white spot formation without colouration and were more tolerant than OR (p < .05) towards excessive white spot formation with slight colouration. The level of treatment satisfaction for slight to severe WSLs without cavitation was higher in OP than OR. Patients with higher education levels had more negative scores for aesthetic perception and treatment satisfaction (p < .05). Patients who brushed teeth more frequently scored lower in treatment satisfaction (p < .05). CONCLUSIONS: Orthodontists were the most critical when evaluating aesthetics and treatment satisfaction for slight to severe WSLs without cavitation. For orthodontic patients, better oral hygiene habits and higher education levels were associated with more critical attitudes towards WSLs.

RESUMO

OBJECTIVE: To identify and summarize the presence and characteristics of dental patient-reported outcomes (dPROs) and dental patient-reported outcome measures (dPROMs) within comparative observational studies published in 5 leading orthodontic journals. METHODS: Electronic searching was performed to identify intervention (therapeutic or preventive) related comparative observational studies published in selected journals between 2015 and 2021. Two authors extracted the characteristics of each included study independently and in duplicate and summarized the dPROs and dPROMs used in these studies. All dPROs were classified into 2 general types (oral health-related quality of life [OHRQoL] and others), while dPROMs were divided into 3 categories (single-item questionnaires, generic multiple-item questionnaires, and specific multiple-item questionnaires). In addition, dPROMs were examined, if they evaluated the 4 dimensions of OHRQoL (oral function, orofacial pain, orofacial appearance, and psychosocial impact). RESULTS: A total of 683 observational studies were eligible and included of which 117 (17.1%) used dPROs and dPROMs. Seven different dPROs (OHRQoL, patients' satisfaction with treatment, preferences, concerns, compliance, duration, and unwanted events) and 33 different dPROMs (including 8 single-item questionnaires, 11 generic multiple-item questionnaires, and 14 specific multiple-item questionnaires) were identified in these studies. OHRQoL was the most commonly used dPRO (92/117, 78.6%), while Oral Health Impact Profile 14 (OHIP-14) was the most frequently used dPROM (20/92, 21.7%). In terms of study design, cross-sectional studies had the highest proportion of dPRO usage (62/148, 41.9%), followed by cohort studies (63/505, 12.5%) and case-control studies (1/30, 3.3%). CONCLUSIONS: Only one-sixth of comparative observational studies published in leading orthodontic journals could reflect patients' perspectives. Observational studies in orthodontics need to provide more patient-important information through the use of dPROs and dPROMs.

RESUMO

The emergence and rapid development of disruptive innovations are quickly turning our profession into personalized dentistry, built upon evidence-based, data-oriented, and patient-centered research. In order to help improve the quality and quantity of patient-centered evidence in dentistry, further promote the wide and standard use of dental patient-reported outcomes (dPROs) and dental patient-reported outcome measures (dPROMs), the Journal of Evidence-Based Dental Practice has put together this special issue, the third of a series entitled Dental Patient-Reported Outcomes Update. A total of 7 solicited articles are collected in this issue. To put them into a broader perspective, this review provides a concise summary of key, selected PRO and dPRO articles published during 2023. A brief introduction to those articles included in this Special Issue follows. Four main domains are covered in this Special Issue: (1) dPROs and digital dentistry, (2) standardization of dPRO-related methodology, (3) current usage of dPROs and dPROMs in published research, and (iv) the significance and relevance of dPRO usage.

RESUMO

OBJECTIVES: Behçet's syndrome (BS) is a rare disease of unknown etiology, with limited reports especially in pediatric BS. The clinical characteristics and phenotypes of pediatric BS as a highly heterogeneous variable vessel vasculitis were investigated in this study. METHODS: A cross-sectional study was conducted to compare clinical variables and descriptive characteristics of BS by age of onset and gender. Cluster analysis was then performed to identify the phenotypes of pediatric BS. RESULTS: A total of 2082 BS patients were included in this study, 1834 adults and 248 children. Compared with adult-onset BS, pediatric BS had a higher incidence of folliculitis [relative risks (RR) and 95% confidence interval (CI) 1.3 (1.0-1.5)], uveitis of the left eye [RR and 95% CI 2.3 (1.0-5.0)], intestinal ulcer complications [RR and 95% CI 2.1 (1.1-4.2)], pericarditis [RR and 95% CI 2.5 (1.0-6.2)], and psychiatric disorders [RR and 95% CI 2.8(1.0-7.9)], while the incidence of thrombocytopenia was lower [RR 0.2 (0.1-1.0)]. Among pediatric BS, females had more genital ulcers, while males were more likely to have skin lesions, panuveitis, vascular involvement, venous lesions, cardiac involvement, and aortic aneurysms. Cluster analysis classified pediatric BS into five clusters (C1-C5): C1 (n = 61, 24.6%) showed gastrointestinal (GI) involvement; C2 (n = 44, 17.7%) was the central nervous system (CNS) type where 23 cases overlapped joint involvement; in C3 (n = 35, 14.1%), all patients presented with arthritis or arthralgia; all patients in C4 (n = 29, 11.7%) manifested ocular involvement, with a few patients overlapping with GI involvement or joint damage; C5 (n = 79, 31.9%) was the mucocutaneous type, presenting both oral ulcers, genital ulcers, and skin lesions. CONCLUSIONS: The clinical features of pediatric and adult BS differ significantly. Male and female pediatric BS also have a distinct demography. Five phenotypes including GI, CNS, joint, ocular, and mucocutaneous types were identified for pediatric BS.

RESUMO

BACKGROUND: The fat mass and obesity-associated protein (FTO) is an RNA demethylase that contributes to several physiological processes. Nonetheless, the impact of FTO on bone remodeling in the midpalatal suture while undergoing rapid maxillary expansion (RME) remains unclear. METHODS: First, to explore the expression of FTO in the midpalatal suture during RME, six rats were randomly divided into two groups: Expansion group and Sham group (springs without being activated). Then, suture mesenchymal stem cells (SuSCs) were isolated as in vitro model. The expression of FTO was knocked down by small interfering RNA to study the effect of FTO on the osteogenic differentiation of SuSCs. Finally, to evaluate the function of FTO in the process of bone remodeling in the midpalatal suture, ten rats were randomly divided into two groups: FB23-2 group (10 µM, a small molecule inhibitor of FTO) and DMSO group (control). RESULTS: Increased arch width and higher expression of OCN and FTO in the midpalatal area were observed in expansion group (P < .05). In the in vitro model, the mRNA expression levels of Runx2, Bmp2, Col1a1, Spp1, and Tnfrsf11b were decreased (P < .05) upon knocking down FTO. Additionally, the protein levels of RUNX2 and OPN were also decreased (P < 0.05). Adding FB23-2, a small-molecule inhibitor targeting FTO, to the medium of SuSCs caused a decrease in the mRNA expression levels of Runx2, Bmp2, Col1a1, Spp1, and Tnfrsf11b (P < 0.05). There was a statistically significant difference in evaluating the expression of OCN and OPN on the palatal suture between the FB23-2 and DMSO groups (P < .05). LIMITATION: The molecular mechanisms by which FTO regulates SuSCs osteogenesis remain to be elucidated. The FTO conditional knock out mouse model can be established to further elucidate the role of FTO during RME. CONCLUSION: FTO contributes to the osteogenic differentiation of SuSCs and plays a promoting role in midpalatal suture bone remodeling during the RME.

RESUMO

Dental patient-centered outcomes can improve the relevance of clinical study results to dental patients and generate evidence to optimize health outcomes for dental patients. Dental patient-reported outcomes (dPROs) are of great importance to patient-centered dental care. They can be used to evaluate the health outcomes of an individual patient about the impact of oral diseases and treatment, and to assess the quality of oral health care delivery for a health care entity. dPROs are measured with dental patient-reported outcome measures (dPROMs). dPROMs should be validated and tested before wider dissemination and application to ensure that they can accurately capture the intended dPROs. Evidence suggests inadequate dPRO usage among dental trials, as well as potential flaws in some existing dPROMs. This Glossary presents a collection of main terms in dental patient-centered outcomes to help clinicians and researchers read and understand patient-centered clinical studies in dentistry.

RESUMO

Thalidomide is a therapeutic option for patients with ß-thalassemia by increasing fetal hemoglobin and thereby reducing the requirement for blood transfusions. However, information on changes in erythropoiesis and iron homeostasis during thalidomide treatment is lacking. This study investigated the effects of thalidomide treatment on hematologic, erythropoietic, and ironstatus parameters in 22 patients with transfusion-dependent ß-thalassemia (TDT). Thalidomide significantly improved anemia endpoints, including increases in hemoglobin (p<0.001), red blood cells (p<0.001), and hematocrit (p<0.001), as well as reducing erythropoietin levels (p=0.033) and ameliorating erythropoiesis. Thalidomide treatment significantly reduced serum iron levels (p=0.018) and transferrin saturation (p=0.039) and increased serum transferrin levels (p=0.030). Thalidomide had no observed effect on serum ferritin or hepcidin, but changes in hepcidin (r=0.439, p=0.041) and serum iron (r=-0.536, p=0.010) were significantly correlated with hemoglobin increment. This comprehensive study indicates that thalidomide treatment can ameliorate erythropoiesis and iron homeostasis in patients with TDT, thus supporting the effectiveness of this drug.

RESUMO

OBJECTIVES: To develop a photochromic bracket adhesive (PCA) with modification using photochromic material and evaluate the biocompatibility, bond strength, photochromic property, and adhesive removal efficiency. MATERIALS AND METHODS: The resin-modified glass ionomer powder was mixed with the photochromic material and then blended with the liquid agent to form PCA. Biocompatibility was evaluated by CCK-8 kit, and shear bond strength (SBS) was measured. Stereoscopic microscopy and quantitative color analysis were used to assess the photochromic property. Bracket bonding and debonding procedures were performed on a head simulator with the assistance of an ultraviolet radiator. The effectiveness of adhesive removal during bonding and debonding procedures was assessed using a stereomicroscope. Removal time was recorded, and the enamel damage index after debonding was analyzed. RESULTS: CCK-8 assay and SBS test indicated that 5wt.% mixing ratios of the photochromic material did not compromise the biocompatibility and SBS of the adhesive (PCA5). PCA5 showed photochromic properties and could help the operator remove adhesive more thoroughly without increasing enamel damage. CONCLUSIONS: Photochromic adhesive (PCA5) can be good for orthodontic adhesive removal and therefore has good clinical translation potential.

RESUMO

Tumor-initiating cells (TICs) reprogram their metabolic features to meet their bioenergetic, biosynthetic, and redox demands. Our previous study established a role for wild-type isocitrate dehydrogenase 1 (IDH1WT) as a potential diagnostic and prognostic biomarker for non-small cell lung cancer (NSCLC), but how IDH1WT modulates NSCLC progression remains elusive. Here, we report that IDH1WT activates serine biosynthesis by enhancing the expression of phosphoglycerate dehydrogenase (PHGDH) and phosphoserine aminotransferase 1 (PSAT1), the first and second enzymes of de novo serine synthetic pathway. Augmented serine synthesis leads to GSH/ROS imbalance and supports pyrimidine biosynthesis, maintaining tumor initiation capacity and enhancing gemcitabine chemoresistance. Mechanistically, we identify that IDH1WT interacts with and stabilizes PHGDH and fragile X-related protein-1 (FXR1) by impeding their association with the E3 ubiquitin ligase parkin by coimmunoprecipitation assay and proximity ligation assay. Subsequently, stabilized FXR1 supports PSAT1 mRNA stability and translation, as determined by actinomycin D chase experiment and in vitro translation assay. Disrupting IDH1WT-PHGDH and IDH1WT-FXR1 interactions synergistically reduces NSCLC stemness and sensitizes NSCLC cells to gemcitabine and serine/glycine-depleted diet therapy in lung cancer xenograft models. Collectively, our findings offer insights into the role of IDH1WT in serine metabolism, highlighting IDH1WT as a potential therapeutic target for eradicating TICs and overcoming gemcitabine chemoresistance in NSCLC.

RESUMO

OBJECTIVE: To compare the dentofacial characteristics of children with and without adenoid and/or tonsillar hypertrophy. METHODS: A consecutive sample of orthodontic patients aged 6-12 that took pre-treatment lateral cephalograms were included in this study. Those with history of previous orthodontic treatment, adenoidectomy or tonsillectomy, or craniofacial anomalies were excluded. The diagnosis of adenoid and tonsillar hypertrophy was based on Fujioka's and Baroni's methods, according to which the subjects were divided into four groups: the adenoid hypertrophy only (AHO) group; tonsillar hypertrophy only (THO) group; combined adenoid and tonsillar hypertrophy (AH+TH) group; and no adenoid or tonsillar hypertrophy (NH) group. Cephalograms were used for skeletal and dental measurement. Data were analyzed using one-way ANOVA, LSD post-hoc tests and Chi-square test. RESULTS: A total of 598 patients were included. Compared with the NH group, the THO group had significantly larger SNB angle (P < 0.001), as well as significantly smaller ANB angle (P<0.001) and Wits value (P = 0.001). The U1-L1 angle of AHO group was significantly smaller than that in the NH group (P = 0.035). The proportion of adenoid hypertrophy in Class II patients was significantly higher than that in Class III patients (P = 0.001). The proportion of tonsillar hypertrophy in Class III patients was significantly higher than that in Class I patients (P < 0.001) and Class II patients (P < 0.001). CONCLUSION: Over 80 % of children seeking orthodontic treatment had either adenoid or tonsillar hypertrophy. Children with adenoid hypertrophy tend to have skeletal Class II malocclusion, while those with tonsillar hypertrophy tend to have skeletal Class III malocclusion.

RESUMO

Elimination of cancer stem cells (CSCs) and reinvigoration of antitumor immunity remain unmet challenges for cancer therapy. Tumor-associated macrophages (TAMs) constitute the prominant population of immune cells in tumor tissues, contributing to the formation of CSC niches and a suppressive immune microenvironment. Here, we report that high expression of inhibitor of differentiation 1 (ID1) in TAMs correlates with poor outcome in patients with colorectal cancer (CRC). ID1 expressing macrophages maintain cancer stemness and impede CD8+ T cell infiltration. Mechanistically, ID1 interacts with STAT1 to induce its cytoplasmic distribution and inhibits STAT1-mediated SerpinB2 and CCL4 transcription, two secretory factors responsible for cancer stemness inhibition and CD8+ T cell recruitment. Reducing ID1 expression ameliorates CRC progression and enhances tumor sensitivity to immunotherapy and chemotherapy. Collectively, our study highlights the pivotal role of ID1 in controlling the protumor phenotype of TAMs and paves the way for therapeutic targeting of ID1 in CRC.

RESUMO

BACKGROUND: Abstracts provide readers a concise and readily accessible information of the trials. However, poor reporting quality and spin (misrepresentation of research findings) can lead to an overestimation in trial validity. This methodological study aimed to assess the reporting quality and spin among randomized controlled trial (RCT) abstracts in pediatric dentistry. METHODS: We hand-searched RCTs in five leading pediatric dental journals between 2015 and 2021. Reporting quality in each abstract was assessed using the original 16-item CONSORT for abstracts checklist. Linear regression analyses were performed to identify factors associated with reporting quality. We evaluated the presence and characteristics of spin only in abstracts of parallel-group RCTs with nonsignificant primary outcomes according to pre-determined spin strategies. RESULTS: One hundred eighty-two abstracts were included in reporting quality evaluation. The mean overall quality score was 4.57 (SD, 0.103; 95% CI, 4.36-4.77; score range, 1-10). Only interventions, objective, and conclusions were adequately reported. Use of flow diagram (P < 0.001) was the only significant factor of higher reporting quality. Of the 51 RCT abstracts included for spin analysis, spin was identified in 40 abstracts (78.4%), among which 23 abstracts (45.1%) had spin in the Results section and 39 in the Conclusions Sect. (76.5%). CONCLUSIONS: The reporting quality of RCT abstracts in pediatric dentistry is suboptimal and the prevalence of spin is high. Joint efforts are needed to improve reporting quality and minimize spin.

RESUMO

Urothelial carcinoma (UC) with deficient mismatch repair (dMMR) is a specific subtype of UC characterized by the loss of mismatch repair (MMR) proteins and its association with Lynch syndrome (LS). However, comprehensive real-world data on the incidence, clinicopathological characteristics, molecular landscape, and biomarker landscape for predicting the efficacy of PD-1/PD-L1 inhibitors in the Chinese patients with dMMR UC remains unknown. We analyzed 374 patients with bladder urothelial carcinoma (BUC) and 232 patients with upper tract urothelial carcinoma (UTUC) using tissue microarrays, immunohistochemistry, and targeted next-generation sequencing. Results showed the incidence of dMMR UC was higher in the upper urinary tract than in the bladder. Genomic analysis identified frequent mutations in KMT2D and KMT2C genes and LS was confirmed in 53.8% of dMMR UC cases. dMMR UC cases displayed microsatellite instability-high (MSI-H) (PCR method) in 91.7% and tumor mutational burden-high (TMB-H) in 40% of cases. The density of intratumoral CD8+ T cells correlated with better overall survival in dMMR UC patients. Positive PD-L1 expression was found in 20% cases, but some patients positively responded to immunotherapy despite negative PD-L1 expression. Our findings provide valuable insights into the characteristics of dMMR UC in the Chinese population and highlights the relevance of genetic testing and immunotherapy biomarkers for treatment decisions.

RESUMO

Cervical cancer (CC) is the most common human gynecological malignancy worldwide. Recently, accumulating evidences revealed the critical functions of miRNAs in the occurrence and development of cervical cancer. In our study, we aimed to demonstrate the function of miR-214-3p in regulating cell metastasis in cervical cancer. We showed low expression of miR-214-3p in cervical cancer cells and demonstrated downregulation of miR-214-3p promoted cervical cancer metastasis. Furthermore, THBS2 was identified as a novel target of miR-214-3p in cervical cancer cells. miR-214-3p suppressed THBS2 expression by directly targeting 3'UTR of THBS2, resulting in the inhibition of cell viability, invasion and migration. Taken together, the results implied inhibited effects of miR-214-3p on cervical cancer and provided new insight into potential ways for cervical cancer diagnosis and treatment.

RESUMO

Antimicrobial mouthwashes are considered to reduce dental plaque biofilm and thus the potential to prevent plaque-induced oral diseases, particularly periodontal diseases. The effectiveness of mouthwashes relates to this antiplaque role, as well as, their tooth-whitening potential and ability to mask/mange malodour (halitosis). There is also a growing interest in the use of mouthwashes as an adjunctive measure in post surgical and post-dental care, while the COVID-19 pandemic has given a new lease of life to mouthwashes as an oral antispetic that may be useful in reducing the oral viral load. The mode of action of mouthwashes varies, depending on their active ingredients, concentrations, and mode and frequency of use, as does their potential effectiveness. This article aims to provide a narrative overview of the evidence of the effectiveness of the most widely used mouthwashes in managing oral diseases, oral conditions, and adjunctive care roles.

RESUMO

Purpose: The purpose of this study was to investigate the expression patterns, predictive significance, and roles in the immune microenvironment of Serpin Family-B Member 7 (SERPINB7) in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC). Methods: The expression of SERPINB7 and its prognostic relevance were evaluated using RNA-seq data from The Cancer Genome Atlas. SERPINB7 regulation of CESC cell growth and metastasis was investigated using MTT, scratch, and Transwell assays. In vivo effects of SERPINB7 were examined in xenograft model mice and differentially expressed genes (DEGs) associated with SERPINB7 were identified to explore its functional role in oncogenesis. Associations between SERPINB7 levels, chemosensitivity, and immune infiltration were assessed, and mutations and methylation of SERPINB7 were evaluated using the cBioPortal and MethSurv databases, respectively. Results: SERPINB7 was up-regulated in CESC samples as well as in other tumors, and patients with higher SERPINB7A mRNA levels exhibited shorter overall survival. The area under the curve for the use of SERPINB7 in CESC diagnosis was above 0.9, and the gene was shown to regulate tumor cell proliferation and metastasis in vitro and in vivo. Overall, 398 DEGs enriched in key CESC progression-related signaling pathways were identified. SERPINB7 expression was additionally correlated with intratumoral immune infiltration and immune checkpoint activity. Patients expressing higher SERPINB7 levels exhibited distinct chemosensitivity profiles, and methylation of the SERPINB7 gene was linked to CESC patient prognostic outcomes. Conclusion: SERPINB7 was found to be a crucial regulator of CESC progression, prognosis, and the tumor immune microenvironment, highlighting its potential as a diagnostic and prognostic biomarker and target for CESC immunotherapy.

RESUMO

OBJECTIVE: With evidence-based dentistry (EBD) having a far-reaching influence on oral healthcare, dental educators worldwide have made joint efforts to integrate EBD-related knowledge and skills into dental education. The present scoping review aims to identify and summarize the existing teaching contents, teaching methods, and assessment strategies of EBD education. METHODS: Electronic (PubMed and Embase) and manual searches were performed to identify articles related to both "dental education" and "evidence-based practice." Based on predetermined eligibility criteria, articles were selected by 2 reviewers, independently and in duplicate. Data synthesis was conducted based on teaching contents, teaching strategies, and teaching assessment. RESULTS: Of the 1758 articles found in the literature searches, 74 were deemed eligible and included in this review. A total of 4 basic skills (problem formulation, literature searching, critical appraisal, and research methodology), 5 teaching methods, and 6 assessment strategies were identified. In most of the articles, 2, or more skills were taught, and a combination of traditional strategies for teaching and its assessment (eg, courses and questionnaire survey) was involved. Other teaching methods, such as journal clubs and workshops, were seldom used, and validated assessment tools accounted for a relatively small proportion of the assessment strategies involved. CONCLUSIONS: The contents, methods and assessment of EBD education have been widely studied and discussed. However, the current literature focuses mainly on teaching of critical appraisal skills, traditional teaching methods, and short-term outcome assessments. Future research in this area can be aimed at integrating all EBD-related skills into educational models, studying multifaceted teaching approaches, and developing comprehensive teaching outcome assessment methods based on validated tools and dental patient-reported outcomes.
