Abstract Objectives Creating environmentally sustainable healthcare culture within the dental field requires embedding the content in the dental curriculum at the undergraduate level. This study aimed to explore the current awareness and drivers among dental students and educators regarding environmentally sustainable dentistry (ESD) in the United Arab Emirates (UAE) and identify barriers and enablers to embrace it. Methods A cross-sectional survey using online questionnaires was carried out in six undergraduate dental education institutes within the UAE. Data analysis included descriptive statistics. Results In total 153 students and 53 educators participated in the survey. Most students and educators were not aware of any ESD content in their curricula. However, the majority of educators were familiar with the concept of ESD, while students were mostly unfamiliar or slightly familiar. Nonetheless, students largely agreed on its importance and their interest in learning it, as they viewed it relevant to their future practice. Educators agreed that the dental profession has a responsibility to be environmentally friendly and expressed their desire in introducing ESD content into the curricula. Several barriers were reported such as lack of knowledge, curricula space, educational resources, and time. Meanwhile, enablers included providing ESD capacity building, training and resources. Conclusions There was no explicit presence of ESD content in the dental curricula in the UAE. Despite the lack of adequate awareness on this topic among educators and more so among students, they both had positive views towards incorporating ESD into dental curricula. Overall, this study highlighted the importance of promoting ESD in dental programs. Clinical significance: ESD is gradually becoming a critical aspect of modern oral healthcare system. It has been mandated in the dental curricula in several regions globally. Embedding ESD in the UAE dental curricula would have several benefits for the environment as well as the future of the dental profession in the region. The clinical significance includes, but not limited to, improved treatment outcomes; patients, students and staff health and well-being; reduced health risks, and cost savings.

ABSTRACT Introduction Oral diseases are more prevalent in people with severe mental illness (SMI) compared to those without mental illnees. A greater focus on oral health is needed to reverse unacceptable but often neglected oral health inequality in people with SMI. This provided the impetus for developing ‘The Right to Smile’ consensus statement. We aimed to develop and disseminate a consensus statement to address oral health inequality, highlighting the main areas for concern and recommending an evidence‐based 5‐year action plan to improve oral health in people with SMI. Methods The Right to Smile consensus statement was developed by experts from several professional disciplines and practice settings (mental, dental and public health) and people with lived experience, including carers. Stakeholders participated in a series of online workshops to develop a rights‐based consensus statement. Subsequent dissemination activities were conducted to maximise its reach and impact. Results The consensus statement was developed to focus on how oral health inequalities could be addressed through a set of 5‐year improvement targets for practice, policy and training. The consensus was reached on three 5‐year action plans: ‘Any assessment of physical health in people experiencing SMI must include consideration of oral health’, ‘Access to dental services for people with SMI needs to improve’ and ‘The importance of oral health for people experiencing SMI should be recognised in healthcare training, systems, and structures’. Conclusion This consensus statement urges researchers, services and policymakers to embrace a 5‐year action plan to improve oral health for people with SMI. Patient or Public Contribution The team included people with lived experience of SMI, their carers/family members and mental and dental health service providers. They were involved in every stage of developing the consensus statement, from conception to development and dissemination.

This research work aims to develop a fault detection and performance monitoring system for a photovoltaic (PV) system that can detect and communicate errors to the user. The proposed system uses real-time data from various sensors to identify performance problems and faults in the PV system, particularly for encapsulation failure and module corrosion. The system incorporates a user interface that operates on a micro-computer utilizing Python software to show the detected errors from the PV miniature scale system. Fault detection is achieved by comparing the One-diode model with a controlled state retrieved through field testing. A database is generated by the system based on acceptable training data and it serves as a reference point for detecting faults. The user is notified of any deviations based on the threshold value from the training data as an indication of an error by the system. The system offers real-time monitoring, easy-to-understand error messages, and remote access capability, making it an efficient and effective tool for both users and maintenance personnel to manage and maintain the PV system.

Abstract Background COVID-19 is a global pandemic affecting all aspects of life in all countries. We assessed COVID-19 knowledge and associated factors among dental academics in 26 countries. Methods We invited dental academics to participate in a cross-sectional, multi-country, online survey from March to April 2020. The survey collected data on knowledge of COVID-19 regarding the mode of transmission, symptoms, diagnosis, treatment, protection, and dental treatment precautions as well as participants’ background variables. Multilevel linear models were used to assess the association between dental academics’ knowledge of COVID-19 and individual level (personal and professional) and country-level (number of COVID-19 cases/ million population) factors accounting for random variation among countries. Results Two thousand forty-five academics participated in the survey (response rate 14.3%, with 54.7% female and 67% younger than 46 years of age). The mean (SD) knowledge percent score was 73.2 (11.2) %, and the score of knowledge of symptoms was significantly lower than the score of knowledge of diagnostic methods (53.1 and 85.4%, P

ObjectiveCOVID-19 pandemic led to major life changes. We assessed the psychological impact of COVID-19 on dental academics globally and on changes in their behaviors.MethodsWe invited dental academics to complete a cross-sectional, online survey from March to May 2020. The survey was based on the Theory of Planned Behavior (TPB). The survey collected data on participants' stress levels (using the Impact of Event Scale), attitude (fears, and worries because of COVID-19 extracted by Principal Component Analysis (PCA), perceived control (resulting from training on public health emergencies), norms (country-level COVID-19 fatality rate), and personal and professional backgrounds. We used multilevel regression models to assess the association between the study outcome variables (frequent handwashing and avoidance of crowded places) and explanatory variables (stress, attitude, perceived control and norms).Results1862 academics from 28 countries participated in the survey (response rate = 11.3%). Of those, 53.4% were female, 32.9% were ConclusionsCOVID-19 had a considerable psychological impact on dental academics. There was a direct, dose-dependent association between change in behaviors and worries but no association between these changes and training on public health emergencies. More change in behaviors was associated with lower country COVID-19 fatality rates. Fears and stresses were associated with greater adoption of preventive measures against the pandemic.

A prosthesis, composed of a steel cable and stress-reducing washers, was developed to prevent failure of laryngoplasty, a common treatment for horses affected by recurrent laryngeal neuropathy. Laryngoplasties were performed on 15 cadaveric larynges using a polyester suture on one side and the cable prosthesis on the other. Each prosthesis was distracted at a displacement rate of 20 mm/s using a servohydraulic materials testing machine until laryngoplasty failed. Distraction force and actuator displacement were recorded and analysed. All 15 laryngoplasties performed with a suture failed at the muscular process at a mean ± s.d. force of 55.8 ± 13.1 N. Six laryngoplasties performed with the cable prosthesis failed at the muscular process at mean force 219.6 ± 125.0 N. In the other 9, the arytenoid cartilage was avulsed from the larynx at mean force 206.4 ± 75.3 N, and the cable then tore through the muscular process at mean force 357.0 ± 32.0 N. The difference in force required to cause failure of laryngoplasty was significant (P<0.0001). Although the prosthesis resisted substantially higher forces than did the suture, the effects of the prosthesis in vivo must be evaluated. [ABSTRACT FROM AUTHOR]

Syria has witnessed the greatest humanitarian crisis of forcibly displaced population since World War II. The present review aimed to outline Syria's profile of the epidemiology and management of early childhood caries (ECC). Before the crisis, the burden of ECC amongst Syrian pre-schoolers had been growing in prevalence and severity. Comparable data showed an increase in the burden of ECC amongst Syrian children aged five years, rising from 74% in 1991 to 81% in 2011, with a dmft value of 8.6. A similar increase was observed in the burden of ECC amongst Syrian children aged three years, rising from 50% in 1991 to 56% in 2011, with a dmft value of 6.1. Whilst there are no data on the burden of ECC during the current crisis, estimates could be extrapolated from data on the current burden of dental caries amongst Syrian primary school children living inside Syria or in informal settlements outside Syria. Such data suggested that the burden of ECC might have further increased amongst Syrian pre-schoolers during the crisis time. This is due to the crisis exacerbating effect on ECC risk factors, in terms of increasing the existing high sugar intake amongst Syrian pre-schoolers as well as increasing different barriers Syrian families face to fresh foods, sugar-free medicines, oral hygiene and fluoride products and accessing essential preventative dental care. Tackling the growing burden of ECC amongst Syrian pre-schoolers should not be postponed till post-crisis time. The seed work for relevant public health interventions could start and be embedded in different health and social initiatives taking place during the time of crisis. A number of public health interventions informed by relevant international and local (Syrian) studies conducted during the time of crisis have been suggested to tackle the burden of ECC amongst Syrian young children. They include a mix of upstream, midstream, and downstream interventions that aim to reduce sugar intake, improve feeding and oral hygiene practices, increase access to an appropriate source of fluoride and build the capacity of the Syrian dental and wider workforce to tackle the growing burden of ECC in Syrian pre-schoolers.

Peripheral blood immunological features were assessed in 21 patients with clinical and angiographic evidence of retinal vasculitis (RV). Abnormalities of humoral and cellular immunity were frequent in this group of patients. Lymphopenia was the most common immunological abnormality, being present in 76% of patients at presentation (p less than 0.05). Peripheral blood T and B cells were decreased with a normal helper (OKT4) to suppressor (OKT8) T cell ratio in 11 patients tested (five with Behçet's syndrome and six with idiopathic RV). Significantly increased concentrations of serum immune complexes were present in 55% of patients (p less than 0.05). Results of the present study indicate the frequent association of peripheral blood immunological abnormalities in patients with active RV and indicate the possible role of immunological mechanisms in its pathogenesis.

Pressures are determined in a layer of fluid bounded by two parallel elastic plates, one of which is harmonically excited at a point. The response of the coupled plate-fluid system is obtained for infinitesimal displacements in both the plate and the fluid. The pressures are obtained through a numerical integration of the inverse Hankel transform along an approximation to the steepest descent path. Some numerical results obtained for frequencies both above and below the coincidence frequency are given. These show a complex spatial variation in pressure in addition to that on the scale of the wavelength in the fluid. [ABSTRACT FROM AUTHOR]

alpha 1 antitrypsin is an important immunoregulatory protein, the serum level of which is genetically determined. Deficient phenotypes of this ubiquitous protease inhibitor are associated with a variety of inflammatory diseases including anterior uveitis. In order to investigate the role of this protease inhibitor in the pathogenesis of retinal vasculitis (RV) 25 patients were investigated. Diseases associated with RV included Behcet's syndrome (8), SLE (2), and sarcoidosis (1). Deficient phenotypes of alpha 1 antitrypsin were not associated with RV. However, the serum alpha 1 antitrypsin level was significantly increased in patients with active RV and paralleled disease activity in patients studied prospectively. [ABSTRACT FROM PUBLISHER]
