Classification and Dynamics of Class of ξ(as)-QSO

The current study provides a new class of ξ(as)-QSO defined on 2D simplex and classifies it into 18 non-conjugate (isomorphic) classes. This classification is based on their conjugacy and the remuneration of coordinates. The current study also examines the limiting points associated with the behavior of trajectories for four classes defined on 2D simplex

Promoting Oral Health for Refugees: An Advocacy Guide

One of the main objectives of the FDI World Dental Federation (FDI) 2018-2021 strategy is to promote oral health among underserved populations globally. The first pillar of FDI’s Vision 2030 advocacy strategy states that essential oral health services should be integrated into universal healthcare packages in every country, and quality oral healthcare should become available, accessible, and affordable to all, with special attention paid to marginalized and vulnerable populations. Refugees are among the most vulnerable groups worldwide. They have limited access to oral health education, oral disease prevention and therapeutic dental care. This is due, in part, to the relatively high cost of restorative treatment, limited access and availability of dentists, unaffordability of dental insurance, and language barriers. Data collected by FDI from 105 National Dental Associations found that a very significant gap exists in oral health policies at global, regional, and national levels. There are limited oral health advocacy initiatives for refugees, who have poor access to therapeutic and preventive interventions related to oral care. This guide was developed to address this gap and to lead the way for national dental associations (NDAs) and other interested stakeholders to: • raise awareness of the burden that refugees face to maintain their own oral health and the challenges that host countries face to maintain good oral health in their populations; • highlight the gaps in data collection and the importance of oral health screening/surveillance for refugees; • provide guidance on measuring and understanding the problem with focused attention on the social determinants of oral health; • support countries that host refugees with tools and strategies that can strengthen their own oral health strategies and programmes; • integrate the management of oral health conditions among refugees into general health services and the provision of care; • mainstream oral health through health systems planning, funding, and implementing oral health promotion and disease prevention intervention among this group

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
