RESUMO
When people experience empathy for a needy stranger, efforts to help are often not far behind. But does empathy actually cause prosocial behavior? And if so, does it activate genuine concern or more self-interested motivations? To rule out the alternative hypothesis that empathy motivates prosocial behavior by generating fear of social disapproval for acting selfishly, Fultz et al. (1986) manipulated empathy for a lonely stranger using perspective-taking instructions; they also manipulated whether subjects believed their decision to help would remain anonymous. However, Fultz et al. conducted their experiment decades ago, with few subjects, and before some potentially important cultural changes in college students' values and social lives. Here, in a preregistered replication with 280 undergraduates, we tested Fultz et al.'s key assertions. The perspective-taking and social evaluation manipulations influenced scores on the manipulation check measures mostly in theory-consistent ways but did not significantly influence helping. Consistent with theory, empathy was positively associated with prosocial behavior. We also found evidence that endorsement of the principle of care reflects genuine concern for needy strangers and that moral identity symbolization reflects a desire to help in order to avoid social disapproval. We consider these results a partially successful replication of key tenets of the empathy-altruism hypothesis, though questions remain about the conditions under which perspective-taking promotes prosocial behavior and about the generalizability of our findings to populations beyond undergraduate women circa 1986. Our results also help illuminate the motivational underpinnings of two individual differences that predicted prosocial behavior in previous research.

RESUMO
OBJECTIVE: High-risk human papillomaviruses (HPV) are an established cause of oropharyngeal cancer. Their relationship with oral cancer remains unclear with detection ranging from 0% to 100%. HPV DNA detection or evidence of exposure alone is insufficient to conclude causality. This systematic review assesses the extent of bias in studies of HPV detection in cancers of the oral cavity. METHODS: PubMed, Ovid MEDLINE, EMBASE, and PsycInfo databases were searched for observational studies reporting the effect of HPV in oral cavity specific cancers. RESULTS: All 15 included studies presented HPV DNA detection or serum HPV-antibodies, none included mRNA E6/E7 analysis. Cases with oral cancer had 5.36 times (95% CI 3.29-8.72) higher odds of having HPV detected compared to controls. The odds of HPV detection were higher in cell-based (OR 6.93; 95% CI 0.82-58.55) and tissue samples (OR 5.28; 95% CI 3.41-8.18) than blood-based samples (OR 3.36; 95% CI 1.53-7.40). CONCLUSION: When cancer site is clearly differentiated between oropharynx and oral cavity, 12 studies showed strong association between HPV and oral cancer, but the available estimates lack internal validity due to inconsistent measurements, high confounding, and lack of gold standard testing. There is not high-quality evidence to conclude a causal relationship of HPV with oral cancer.
RESUMO
OBJECTIVES: Dentists manage a variety of oral infections in clinical practice. Inappropriate antimicrobial prescribing by dentists occurs frequently and antimicrobial stewardship strategies should include dentistry. The aim of this retrospective analysis of the Australian Hospital National Antimicrobial Prescribing Survey (Hospital NAPS) dataset, was to describe the types of oral and dental indications where antimicrobials were prescribed, and assess the guideline compliance and appropriateness of the antimicrobials in Australian hospitals. METHODS: Data from the Hospital NAPS was extracted for oral and dental indications from 2013 to 2022. The types of oral and dental indications presented, and the corresponding antimicrobials prescribed were assessed for compliance according to national prescribing guidelines, and appropriateness according to the NAPS structured algorithm. RESULTS: A total of 8,001 prescriptions for 7,477 patients were identified, from 433 hospitals. Antifungal, antibiotic and antiviral agents accounted for 84.5 %, 15.4 % and 0.03 % of prescriptions respectively. A greater proportion of antibiotics were prescribed in regional and rural areas compared to antifungals. The prescriptions assessed as compliant were 80.0 % and 44.7 % of antifungals and antibiotics respectively. Prescriptions assessed as appropriate were 84.4 % of antifungals, and 65.3 % of antibiotic prescriptions. CONCLUSIONS: A wide variety of antimicrobials were used with moderate levels of compliance and appropriateness. Future interventions should include targeted education, utilisation of prescribing guidelines, and tools to diagnose and manage oral and dental conditions. Consideration can be given to adjustment of the Hospital NAPS tool to cater for oral conditions and include the provision of dental treatment in the management of these infections. CLINICAL SIGNIFICANCE: A wide variety of oral and dental conditions are presented in Australian hospital settings, managed by a range of antibiotics and antifungals, with moderate levels of compliance to guidelines and appropriateness. Antimicrobial stewardship strategies should target and support dentistry in hospital settings.

OBJECTIVES: Special needs dentistry (SND) is a vast and fragmented field of study. This comprehensive bibliometric analysis aimed to evaluate the scope of SND, including the existing knowledge base, distribution structure, quantitative relationships, and research trends. MATERIAL AND METHODS: A systematic search was conducted on March 10, 2022, using the Web of Science Core Collection database, covering the period from 1985 to 2021, focusing on studies reporting on special needs populations in a dentally relevant context. Records were title-screened and analyzed for key bibliometric indicators. RESULTS: Among 48,374 articles, 13,869 underwent bibliometric analysis. Peak SND research occurred during 1985-1997. United States led in productivity, trailed by Brazil and Japan. University of Sao Paulo excelled in Brazil, University of Washington and University of North Carolina in the United States. The Journal of Dental Research was the most productive source of research and also had the highest number of citations, followed by Community Dentistry and Oral Epidemiology. Keyword analysis revealed that "elderly", "caries", and "epidemiology" were the most commonly used author keywords. CONCLUSIONS: This study represents the first bibliometric analysis of SND literature. It emphasizes the need for increased collaboration between institutions and authors. Furthermore, it suggests focusing on research input from non-dental disciplines and populations with rarer intellectual or developmental conditions.

Differences in shape can be a distinguishing feature between different cell types, but the shape of a cell can also be dynamic. Changes in cell shape are critical when cancer cells escape from the primary tumor and undergo major morphological changes that allow them to squeeze between endothelial cells, enter the vasculature, and metastasize to other areas of the body. A shift from rounded to spindly cellular geometry is a consequence of epithelial-mesenchymal plasticity, which is also associated with changes in gene expression, increased invasiveness, and therapeutic resistance. However, the consequences and functional impacts of cell shape changes and the mechanisms through which they occur are still poorly understood. Here, we demonstrate that altering the morphology of a cell produces a remodeling of calcium influx via the ion channel PIEZO1 and identify PIEZO1 as an inducer of features of epithelial-to-mesenchymal plasticity. Combining automated epifluorescence microscopy and a genetically encoded calcium indicator, we demonstrate that activation of the PIEZO1 force channel with the PIEZO1 agonist, YODA 1, induces features of epithelial-to-mesenchymal plasticity in breast cancer cells. These findings suggest that PIEZO1 is a critical point of convergence between shape-induced changes in cellular signaling and epithelial-mesenchymal plasticity in breast cancer cells.

Machine learning analyses within the realm of oral cancer outcomes are relatively underexplored compared to other cancer types. This study aimed to assess the performance of machine learning algorithms in identifying oral cancer patients, utilizing microRNA expression data. In this study, we implemented this approach using a panel of oral cancer-associated microRNAs sourced from standard incisional biopsy specimens to identify cases of oral squamous cell carcinomas (OSCC). For the model development process, we used a dataset comprising 30 OSCC and 30 histologically normal epithelium (HNE) cases. We initially trained a logistic regression prediction model using 70 percent of the dataset, while reserving the remaining 30 percent for testing. Subsequently, the model underwent hyperparameter tuning resulting in enhanced performance metrics. The hyperparameter-tuned model exhibited high accuracy (0.894) and ROC AUC (0.898) in predicting OSCC. Testing the model on cases of potentially malignant disorders (OPMDs) revealed that leukoplakia with mild dysplasia was predicted as having a high risk of progressing to OSCC, emphasizing machine learning's advantage over histopathology in detecting early molecular changes. These findings underscore the necessity for further refinement, incorporating a broader set of variables to enhance the model's predictive capabilities in assessing the risk of oral potentially malignant disorders.

Detection of subjects with oral potentially malignant disorders in a population is key to early detection of oral cancer (OC) with consequent reduction of cancer-related morbidity and mortality. Our aim was to investigate the prevalence and associated risk factors for OPMD in representative provinces of Indonesia. This cross-sectional study was undertaken in five Indonesian provinces: West Java (WJ), Jakarta (JKT), West Papua (WP), West Kalimantan (WK) and Banda Aceh (BA). Respondents answered a previously validated questionnaire including information on ethnicity, occupation, socioeconomic status (SES), oral health practices, and behaviours associated with oral cancer. An oral examination was undertaken using WHO standardized methodology. Data were analysed using ANOVA, Chi-Square, and logistic regression to assess association between risk factors and mucosal disease. A total of 973 respondents between the ages of 17 and 82 years was enrolled (WJ 35.5%,JKT 13.3% WP 18.3%, WK 9%, BA 23.9%). Tobacco smoking (14.8%), Betel quid (BQ) chewing (12.6%) and alcohol drinking (4%) varied geographically. A well-established OPMD was detected in 137 (14.1%) respondents and 2 (0.2%) presented with chronic ulceration later diagnosed as OC. Leukoplakia was the most common OPMD found (9.7%), while the prevalence of oral submucous fibrosis (OSMF), not previously described in the nation, was 2.3%. Poor knowledge of OC risk factors, poor oral hygiene behaviours, low-income SES and ethnicity were significantly associated with the presence of an OPMD. There is a previously under-reported high prevalence of OPMD in Indonesia. Overall, we found a strong correlation between the presence of an OPMD and individual habituation to known risk factors.

INTRODUCTION: Special needs dentistry (SND) is an emerging dental specialty, with ongoing developments in education and clinical practice focused towards the tailored management of individuals with special needs (SN). Patients with SN have a higher prevalence of oral diseases and unmet dental needs compared to the general population. Although inadequate training and experience in managing patients with SN has been highlighted as a significant barrier to accessing care, there is limited data about the extent of SND teaching at the entry-to-practice or higher levels. METHODS: This work is the first to map SND curricula globally, across 180 countries and 1265 dental schools. RESULTS: Although 74.62% of dental schools were found in developing economies, the distribution of programs that reported SND in their courses was highly skewed towards developed countries. In terms of advanced degrees, beyond basic entry-to-practice training, the USA delivered 60% of the SND programs, followed by Canada (15.56%), UK (13.33%), and Australia (8.89%). The term SND appeared in 33.95% of entry-to-practice level program curricula and was less commonly used in transitioning economies. Only 112 SND-specialized practitioners enter the workforce globally each year from developed economies, and all but three advanced degrees are found in G7 countries. CONCLUSION: By exploring the impact of economic status on its distribution, this paper highlighted the lack of SND representation in dental curricula, especially amongst programs in transitioning or developing economies. Education of both general dentists and specialists is critical as a collaborative effort is needed to manage the growing population of patients with SN.

If group norms and decisions foster peace, then understanding how norms and decisions arise becomes important. Here, we suggest that neither norms nor other forms of group-based decision making (such as offering restitution) can be adequately understood without simultaneously considering (i) what individual psychologies are doing and (ii) the dynamics these psychologies produce when interacting with each other.

BACKGROUND: Reliable assessment of suicide and self-harm risk in emergency medicine is critical for effective intervention and treatment of patients affected by mental health disorders. Teams of clinicians face the challenge of rapidly integrating medical history, wide-ranging psychosocial factors, and real-time patient observations to inform diagnosis, treatment, and referral decisions. Patient outcomes therefore depend on the reliable flow of information through networks of clinical staff and information systems. This study aimed to develop a quantitative data-driven research framework for the analysis of information flow in emergency healthcare settings to evaluate clinical practice and operational models for emergency psychiatric care. METHODS AND FINDINGS: We deployed 2 observers in a tertiary hospital emergency department during 2018 for a total of 118.5 h to record clinical interactions along patient trajectories for presentations with risk of self-harm or suicide (n = 272 interactions for n = 43 patient trajectories). The study population was reflective of a naturalistic sample of patients presenting to a tertiary emergency department in a metropolitan Australian city. Using the observational data, we constructed a clinical interaction network to model the flow of clinical information at a systems level. Community detection via modularity maximization revealed communities in the network closely aligned with the underlying clinical team structure. The Psychiatric Liaison Nurse (PLN) was identified as the most important agent in the network as quantified by node degree, closeness centrality, and betweenness centrality. Betweenness centrality of the PLN was significantly higher than expected by chance (>95th percentile compared with randomly shuffled networks) and removing the PLN from the network reduced both the global efficiency of the model and the closeness centrality of all doctors. This indicated a potential vulnerability in the system that could negatively impact patient care if the function of the PLN was compromised. We developed an algorithmic strategy to mitigate this risk by targeted strengthening of links between clinical teams using greedy cumulative addition of network edges in the model. Finally, we identified specific interactions along patient trajectories which were most likely to precipitate a psychiatric referral using a machine learning model trained on features from dynamically constructed clinical interaction networks. The main limitation of this study is the use of nonclinical information only (i.e., modeling is based on timing of interactions and agents involved, but not the content or quantity of information transferred during interactions). CONCLUSIONS: This study demonstrates a data-driven research framework, new to the best of our knowledge, to assess and reinforce important information pathways that guide clinical decision processes and provide complementary insights for improving clinical practice and operational models in emergency medicine for patients at risk of suicide or self-harm. Our findings suggest that PLNs can play a crucial role in clinical communication, but overreliance on PLNs may pose risks to reliable information flow. Operational models that utilize PLNs may be made more robust to these risks by improving interdisciplinary communication between doctors. Our research framework could also be applied more broadly to investigate service delivery in different healthcare settings or for other medical specialties, patient groups, or demographics.

BACKGROUND: Coffee is one of the most consumed beverages in the world. Containing an abundance of bioactive molecules including polyphenols and flavonoids, the constituents of this beverage may exert antiproliferative, antioxidant and anti-inflammatory effects. METHODS: We conducted a systematic review to summarise the available evidence on the anticancer effects of coffee constituents and their potential therapeutic use for oral squamous cell carcinoma (OSCC). Studies were identified through a comprehensive search of OVID MEDLINE, OVID EMBASE and Web of Science, including articles from any year up to 15 May 2023. RESULTS: Of the 60 reviewed papers, 45 were in vitro, 1 was in silico and 8 were in vivo exclusively. The remaining studies combined elements of more than one study type. A total of 55 studies demonstrated anti-proliferative effects, whilst 12 studies also investigated migration and invasion of neoplastic cells. The constituents studied most frequently were quercetin and epigallocatechin gallate (EGCG), demonstrating various cytotoxic effects whilst also influencing apoptotic mechanisms in cancer cell lines. Dose-dependent responses were consistently found amongst the studied constituents. CONCLUSION: Whilst there was heterogeneity of study models and methods, consistent use of specific models such as SCC25 for in vitro studies and golden hamsters for in vivo studies enabled relative comparability. The constituents of coffee have gained significant interest over the last 30 years, particularly in the last decade, and present an area of interest with significant public health implications. Currently, there is a paucity of literature on utilization of active coffee constituents for the therapeutic treatment of oral cancers.

INTRODUCTION: The most effective means for reducing oral cancer (OC) mortality is by preventing late-stage disease. Early diagnosis can be improved by increasing awareness among healthcare providers, specifically general dental practitioners (GDP). Therefore, our study aimed to assess GDPs' knowledge of OC risk factors and perceived competence in performing conventional oral examination (COE) in routine dental practice. MATERIAL AND METHODS: This was a cross-sectional study conducted in five provinces of Indonesia, namely: Aceh, Banda Aceh (BA); Bandung, West Java (WJ); special district Jakarta (JKT), JKT; Pontianak, West Kalimantan (WK); and Sorong, West Papua (WP). The local Dental Association or Faculty of Dentistry invited the GDPs to attend an education program and complete the survey. RESULTS: One hundred seventy-seven GDPs completed the survey (WJ, n = 63; BA, n = 44, JKT, n = 27; WP, n = 23; and WP, n = 20). A large proportion (164 out of 177, 92.66%) of GDPs felt they had received insufficient training to equip them to diagnose OC and as many as 22.6% (n = 40) did not refer to specialists when they found suspicious mucosal lesions. Notwithstanding the significant regional variations, the majority of Indonesian GDPs self-reported inadequate knowledge and awareness of OC and scarce confidence in performing COE. CONCLUSION: GDP knowledge of OC risk factors and COE is key to improving early diagnosis of OC at a community level. Therefore, it is suggested that the lack of knowledge and confidence of GDPs reported here should be addressed through the national dental curriculum in Indonesia.

PURPOSE: Prior studies explored factors influencing dental study choice, but shifts from BDSc to DDS degrees in some countries impact demographics and motivations, potentially affecting the dental workforce. The aim of this study was to establish Australian DDS and BOH students' sociodemographics and career motivations. METHODS: Questionnaires conducted in mid-2019 assessed sociodemographic profiles and career motivations. Statistical analysis utilized descriptive statistics and Fisher's exact test. RESULTS: The overall response rate was 71.3%. DDS students had an average age of 25.2 years, while BOH students averaged 21.5 years. Most BOH (80.7%) and DDS students (52.0%) were female. They were mainly single, local, Australian citizens from metropolitan areas. Self-motivation ranked highest, particularly for DDS students (P < 0.05). Significant motivators included healthcare occupation, helping others, interesting career, and flexible hours (P < 0.05). DDS students were more motivated by flexible hours and independence (P < 0.05), while females emphasized a healthcare profession (P = 0.003). International students were motivated by being their own boss (P = 0.003), and private school graduates valued lifestyle within the profession (P = 0.049). CONCLUSION: Despite sociodemographic changes, the main motivations for studying dentistry remain consistent. DDS students prioritized lifestyle factors such as time and remuneration over BOH students.

BACKGROUND: Micronutrients are vital for general and oral health, and their potential anti-cancer properties are documented. We explore beneficial vitamins for oral potentially malignant disorders (OPMDs) and oral cancer (OC), assessing the therapeutic impacts of essential vitamin supplementation. METHODS: We systematically review evidence on vitamin supplementation's therapeutic effects for OPMDs and OC. Relevant studies were identified through comprehensive searches of MEDLINE, Evidence-Based Medicine, and Web of Science until 16 May 2023. All studies underwent risk of bias using criteria modified from the Office of Health Assessment and Translation (OHAT) tool. RESULTS: We analysed 80 papers. Vitamin K, studied in vitro, shows promising therapeutic potential. Vitamin C, investigated in vivo (animals and humans), demonstrated mixed animal results and generally positive human trial effects. Vitamin A's efficacy varied, with positive monotherapy or adjunct effects. Vitamins B and D showed therapeutic benefits. Oral cancer research was extensive, with a focus on oral lichen planus and oral leukoplakia among the 11 OPMDs. All bias levels were reported in 'selective reporting' and 'performance', except for "definitely high" in the 'selection', 'detection', and 'attrition/exclusion' domains. CONCLUSIONS: Evidence of vitamin interventions for OPMDs and OC ranges from mixed to promising. Standardizing the study design and outcomes would enhance future research.
RESUMO
This is the concluding article in the supplement on the role of mouthwashes in oral care, which summarises the current guidelines across the globe regarding their acceptable adjunctive use for managing caries, gingivitis, and periodontal disease. Based on moderate evidence for clinical effectiveness, most current guidelines suggest fluoride mouthwashes for the management of dental caries, and chlorhexidine for the management of periodontal diseases. However there still appears to be gaps in the literature underpinning these recommendations. Importantly, all evidence supports such mouthwash use "adjunctively," alongside mechanical oral hygiene measures. Other antimicrobial mouthwashes such as essential oils and cetylpyridinium chloride may also be clinically effective against plaque and gingivitis, but there is a current lack of robust evidence of natural mouthwashes to recommend their adjunctive use. The authors of the current review are of the view that mouthwashes may not be of much value in those with good periodontal health or low caries risk. The reasons for this are, the potential i) risks of allergic reactions, ii) dysbiosis of the oral microbiota, iii) emergence of antimicrobial resistance, and iv) deleterious effects on the environment. There is, however, much empirical research needed on mouthwashes, particularly in vivo research derived through clinical trials. Thus, dental practitioners need to keep abreast of the evidence base on the current, and the emerging, over-the-counter mouthwashes, and pay heed to the consensus views emanating from systematic reviews, as well as international guidelines on mouthwashes.

This narrative literature review is the first in a 6-section supplement on the role of mouthwashes in oral care. This introduction briefly summarises current knowledge on antimicrobial mechanisms, relating to some of the most common over-the-counter mouthwash products available worldwide: chlorhexidine, hydrogen peroxide, cetylpyridinium chloride, povidone iodine, and essential oils. The aim of this first article is to describe how mouthwashes "kill" pathogenic microbes when used adjunctively and thus provide a basis for their widespread use to manage key oral diseases, namely caries, gingivitis, and periodontal disease. This article therefore sets the scene for subsequent, more detailed exploration of mouthwashes regarding their clinical effectiveness, impact on the oral microbiome, and possible effects on systemic health as well as natural alternatives and future directions. Other than the clinical effectiveness (for certain agents) of mouthwashes, on many topics there remains insufficient evidence for systematic review or formulation of robust national guidelines. The supplement, therefore, compiled by an international task team, is aimed at general dental practitioners across the globe, as an easy-to-read guide for helping to advise patients on mouthwash use based on the current best available evidence.

This narrative review summarises "alternative" or "natural" over-the-counter (OTC) mouthwashes not covered elsewhere in this supplement and newly emerging products, as potential mouthwashes of the future. The "natural" mouthwashes reviewed include saltwater, baking soda, coconut oil, charcoal, propolis, seaweeds, and probiotics. Other than essential oils, it is apparent that their clinical effectiveness is still under debate, but there is some evidence to suggest that propolis reduces plaque and gingivitis. This review also covers the host immune response, via novel anti-inmmunomodulant mouthwashes, such as erythropoietin to reduce inflammation with oral mucositis (OM) after radiotherapy. The emerging concept of nanoparticle-containing mouthwashes, such as iron oxide, is further discussed for OM, this agent having the potential for more targeted delivery of chemical antimicrobials. Unfortunately, there are impacts on the environment of widening mouthwash use with more new products, including increased use of packaging, antimicrobial resistance, and possible detrimental effects on marine life. Further, there are roadblocks, relating to regularly approvals and side effects, that still need to be overcome for any OTC deivered immunomodulant or nanoformulation mouthwashes. Despite these caveats, there are many new mouthwashes under development, which could help manage major oral diseases such as caries, gingivitis, and periodontal disease.

The potential association between antimicrobial mouthwash use and systemic health has gained attention in recent years with reports highlighting how some common systemic conditions are influenced by the use of different types of mouthwashes. In this context, links between mouthwash use and cardiovascular disease, diabetes mellitus, oral cancer, Alzheimer's disease, and preeclampsia have been proposed, albeit with limited levels of evidence. Chlorhexidine mouthwash in particular has been the most widely studied agent while available data on other types of over-the-counter mouthwashes are generally scarce. Furthermore, there is currently no evidence-based recommendations on the appropriate use of mouthwashes during pregnancy. This article will present the current evidence on the association between mouthwash use and the aforementioned conditions with emphasis on the mechanisms that may underlie such an association.

Boyer suggests that laws cannot account for ownership intuitions, but there may be situations when intuitions hew to laws almost perfectly. Laws granting governments taxation powers provide an interesting case study. We report data here suggesting that people's intuitions track law very closely, and are unaffected by manipulating a P() tag input. We propose two hypotheses to explain this finding.

BACKGROUND: Oral mucosal conditions are commonly experienced in the general population and can have a negative impact on one's quality of life. This study evaluated the ability of Australian pharmacists and final-year pharmacy students to recognise and manage these common oral mucosal diseases through the use of case vignettes. METHODS: Australian pharmacists and final-year pharmacy students were invited through social media, university learning management systems, or email to complete an online questionnaire consisting of six case vignettes covering topics relating to common oral mucosal presentations. RESULTS: A total of 65 pharmacists and 78 students completed the questionnaire. More than 50% of the participants reported having seen all types of oral mucosal presentations, except for denture stomatitis, in their practice. The provision of best practice recommendations was reported by only 14%, 15%, 8%, and 6% of the participants for geographic tongue, hairy tongue, angular cheilitis, and denture-associated stomatitis, respectively, whereas 82% offered an appropriate anti-viral treatment for cold sore and 33% provided the best practice recommendations for oral thrush. CONCLUSION: This study emphasised the importance of further developing and integrating best practice oral healthcare training programs specifically tailored to the Australian pharmacy profession.
