Abstract Background The demographic changes affecting Switzerland and other European countries, including population ageing, will continue to challenge policymakers in building accessible, affordable, comprehensive and high-quality long-term care (LTC) systems. The purpose of this paper is to investigate how Switzerland’s LTC system compares to other European countries, in order to inform how to respond to the increasing need for LTC. We carried out a descriptive study using secondary data from key national and international organizations. Methods By comparing the financing, workforce, service delivery and need for LTC in Switzerland, Germany, Italy, Norway and the United Kingdom, we described similarities and differences in these five European countries between 2005-2019. Thirty-three indicators within five domains were analysed: (1) Population statistics and health expenditure, (2) Need for LTC, (3) LTC financing, (4) LTC service delivery, and (5) LTC workforce. Results Switzerland has the highest life expectancy in comparison to the other four high-income countries. However, similarly to other countries, the years lived with disability are increasing in Switzerland. Switzerland’s public expenditure on LTC as a share of GDP is lower than that of Norway and Germany, yet out-of-pocket expenditure on LTC is highest in Switzerland. Switzerland has the highest proportion of persons receiving formal LTC both in institutions and at home. Switzerland has had the most pronounced increase in the proportion of over 65-year-olds receiving LTC at home. Even though more than fourfold more persons receive care at home, Switzerland still has more workforce in LTC institutions than in home-care. In comparison to Germany and the UK, Switzerland has a lower number of informal carers as a proportion of 50-year-olds and over, as well as fewer nationally available services for informal carers compared to Germany, Italy, Norway and the UK. Conclusions Our comparative study corroborates the importance of improving the affordability of LTC, continuing to support the movement towards home care services, improving the support given to both the professional workforce and informal carers, and improving the amount and quality of LTC data. It also provides a valuable contrast to other European countries to support evidence-informed policymaking.

There is an increasing demand to utilize technological possibilities in the Nordic public sector. Automated decision-making (ADM) has been deployed in some areas towards that end. While ADM is associated with a range of benefits, research shows that its use, with elements of AI, also implicates risks of discrimination and unfair treatment, which has stimulated a flurry of normative guidelines. This article seeks to explore how a sample of these international high-level principled ideas on fairness translate into the specific governance of ADM in national public-sector authorities in Sweden. It does so by answering the question of how ideas about AI ethics and fairness are considered in relation to regulation on anti-discrimination in Swedish public-sector governance. By using a Scandinavian institutionalist approach to translation theory, we trace how ideas about AI governance and public-sector governance translate into state-authority practice; specifically, regarding the definition of ADM, how AI has impacted it as both discourse and technology, and the ideas of ‘ethicsʼ and ‘discriminationʼ. The results indicate that there is a variance in how different organizations understand and translate ideas about AI ethics and discrimination. These tensions need to be addressed in order to develop AI governance practices.

Background and Objective: Limited access to health services and low educational levels are factors in the rural population that are associated with the development of oral pathologies. However, the specific risk indicators contributing to erosive tooth wear (ETW) in these populations remain unclear. The objective of this study was to identify risk indicators associated with the prevalence of erosive tooth wear (ETW) in schoolchildren aged 8–12 years from rural and urban areas in the State of Mexico. Methods: A cross-sectional study was carried out in public schools in rural and urban areas. The prevalence of ETW was evaluated using the Basic Erosive Wear Examination (BEWE). The risk indicators studied were gastroesophageal reflux, vomiting, vitamin C, food, beverages, dental hygiene, bruxism, and hyposalivation. Logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (CI). Results: The prevalence of ETW was higher in the rural area (77.3%) compared to the urban area (51.2%) (p = 0.001). The odds of presenting ETW were more than twice in schoolchildren from rural areas compared to those from urban areas (OR: 2.25, 95% CI: 1.11–3.98). Risk indicators varied between rural and urban populations, with different factors such as the consumption of fresh tomato sauce, orange, tangerine, atole (artisanal corn-based drink), and teeth grinding in the rural area, and lemon, soft drink, fruit juice consumption, and the simplified oral hygiene index in the urban area (p < 0.05). Conclusions: To prevent ETW, strategies offering tailored dietary and hygiene advice should be proposed, considering the specific conditions of each geographic area.

Abstract Endoscopes navigate within the human body to observe anatomical structures with minimal invasiveness. A major shortcoming of their use is their narrow field‐of‐view during navigation in large, hollow anatomical regions. Mosaics of endoscopic images can provide surgeons with a map of the tool's environment. This would facilitate procedures, improve their efficiency, and potentially generate better patient outcomes. The emergence of magnetically steered endoscopes opens the way to safer procedures and creates an opportunity to provide robotic assistance both in the generation of the mosaic map and in navigation within this map. This paper proposes methods to autonomously navigate magnetic endoscopes to 1) generate endoscopic image mosaics and 2) use these mosaics as user interfaces to navigate throughout the explored area. These are the first strategies, which allow autonomous magnetic navigation in large, hollow organs during minimally invasive surgeries. The feasibility of these methods is demonstrated experimentally both in vitro and ex vivo in the context of the treatment of twin‐to‐twin transfusion syndrome. This minimally invasive procedure is performed in utero and necessitates coagulating shared vessels of twin fetuses on the placenta. A mosaic of the vasculature in combination with autonomous navigation has the potential to significantly facilitate this challenging surgery.

Documentos oficiais e pesquisas científicas explicitam que a juventude brasileira pobre se insere em trabalhos informais e uberizados por necessidade, e não por desejo. Este estudo etnográfico proporcionou encontros em profundidade com jovens entregadores de comida na Paraíba/Brasil, durante os anos de 2019 e 2020, utilizando cadernos de campo, questionário socioeconômico e dados audiovisuais. Realizou-se análises de dados descritivas e teóricas, com enquadramento teórico de base materialista histórica. Identificou-se problemáticas sociais e de trabalho, assim como repercussões negativas do trabalho informal/uberizado na educação de jovens. Aponta-se que os serviços responsáveis (ligados aos jovens, à educação e ao trabalho) devem elaborar estratégias intersetoriais de inserção/permanência de jovens na educação e no mercado de trabalho, sempre compreendendo as especificidades das juventudes, a importância da educação e da inserção em trabalhos dignos, seguros e próximos dos desejos dos envolvidos.

Abstract To investigate the effect of some polyphenol-rich plant extracts on the protection of dentine against demineralization, both acting on the dentine and on the salivary pellicle. Dentine specimens (n = 180) were randomly distributed into 6 experimental groups (n = 30/group): Control (deionized water), Açaí extract, Blueberry extract, Green tea extract, Grape seed extract, and Sn2+/F− (mouthrinse containing stannous and fluoride). Each group was further divided into two subgroups (n = 15), according to the site of action of the substance: on the dentine surface (D) or on the salivary pellicle (P). The specimens were submitted to 10 cycles: 30 min incubation in human saliva (P) or only in humid chamber (D), 2 min immersion in experimental substances, 60 min of incubation in saliva (P) or not (D), and 1 min erosive challenge. Dentine surface loss (DSL), amount of degraded collagen (dColl) and total calcium release were analyzed. Green tea, Grape seed and Sn2+/F− showed significant protection, with least DSL and dColl. The Sn2+/F− showed better protection on D than on P, whereas Green tea and Grape seed showed a dual mode of action, with good results on D, and even better on P. Sn2+/F− showed the lowest values of calcium release, not differing only from Grape seed. Sn2+/F− is more effective when acting directly on the dentine surface, while Green tea and Grape seed have a dual mode of action: with a positive effect on the dentine surface itself, but an improved efficacy in the presence of the salivary pellicle. We further elucidate the mechanism of action of different active ingredients on dentine erosion, where Sn2+/F− acts better on the dentine surface, but plant extracts have a dual mode of action, acting on the dentine itself as well as on the salivary pellicle, improving the protection against acid demineralization.

Abstract The aims of this study were to 1) assess the association between erosive tooth wear (ETW) according to the BEWE (Basic Erosive Wear Examination) scoring system and salivary parameters and 2) compare salivary parameters according to ETW severity in the subgroup of children with ETW. This cross-sectional study included 52 preschool children aged 5 years paired by sex. A calibrated examiner assessed ETW using BEWE criteria, and stimulated saliva was collected to determine salivary flow, osmolality, pH, and buffering capacity. The children were divided into two groups: without ETW (n=26; BEWE score 0) and with ETW (n=26; BEWE scores 1 and 2). Logistic regression analysis was used to determine the magnitude of the association between ETW and salivary parameters and estimates of odds ratios (OR). In the unadjusted analysis, the ETW group was more likely to have lower salivary flow (OR = 0.079; 95%CI = 0.013–0.469; p = 0.005) and lower osmolality (OR = 0.993; 95%CI = 0.985–1.000; p = 0.049). In the adjusted analysis, salivary flow remained significantly associated with ETW (OR = 0.087; 95%CI = 0.014–0.533; p = 0.008). Lower salivary osmolality values were observed in ETW, especially in preschool children with more severe ETW (BEWE score 2). Receiver operating characteristic (ROC) determined a salivary osmolality cutoff point of < 201 for the presence of ETW. In conclusion, salivary flow rate was significantly associated with ETW prevalence. Lower values of salivary osmolality were observed in preschool children with distinct erosive lesions with significant loss of tooth structure (BEWE 2).

Abstract The objective of this study was to compare the protein profile of the acquired enamel pellicle (AEP) formed in vivo in patients with or without gastroesophageal reflux disease (GERD), and with or without erosive tooth wear (ETW). Twenty-four volunteers were divided into 3 groups: 1) GERD and ETW; 2) GERD without ETW; and 3) control (without GERD). The AEP formed 120 min after prophylaxis was collected from the lingual/palatal surfaces. The samples were subjected to mass spectrometry (nLC-ESI-MS/MS) and label-free quantification by Protein Lynx Global Service software. A total of 213 proteins were identified, or 119, 92 and 106 from each group, respectively. Group 2 showed a high number of phosphorylated and calcium-binding proteins. Twenty-three proteins were found in all the groups, including 14-3-3 protein zeta/delta and 1-phosphatidylinositol. Several intracellular proteins that join saliva after the exfoliation of oral mucosa cells might have the potential to bind hydroxyapatite, or participate in forming supramolecular aggregates that bind to precursor proteins in the AEP. Proteins might play a central role in protecting the dental surface against acid dissolution.

The significance of reduplication in language studies was to construct a linguistics pattern. However, linguists tend to disregard the functions of individual creativity and the core language meaning-making approach at the discourse level. Therefore, we should investigate this intriguing topic more to describe the repetition of words. Many studies analyzed classification reduplication in Acehnese through documentation techniques, in contrast, this current study investigated classifications and meanings of reduplication in Acehnese through observation and interview. Sulaiman's paradigm as the framework stated that reduplication had three parts: complete, affix, and ablaut reduplication. In addition, the researchers used the Ali et al. framework, which suggested eight meanings of reduplication, mainly grammatical meanings. The findings revealed that full reduplication was the most common among the 100 data of utterances. Furthermore, the meanings of reduplications are to convey the collective and distributive meaning, to express resemblance, and to express simultaneously and continuously were not discovered. The current study looked at how people could use morphological perspectives on reduplication in community discussions. Acehnese reduplication may vanish.

Abstract Polyphenols interact with salivary proteins and thus can improve the pellicle’s erosion protective properties. This effect could be exploited to create rinsing solutions with polyphenols as active ingredients for erosion prevention. Different from the current gold standard for erosion protective rinsing solutions, these rinses would not rely on stannous ions. This would offer alternatives for patients with concerns regarding the composition of rinsing solutions and preferring bio-products. Objective To develop an erosion-preventive rinsing solution containing natural polyphenol-rich extracts. Methodology Solutions were prepared with polyphenols from either grapeseed extract or cranberry extract, 500 ppm fluoride added, and additionally flavors and sweeteners. Controls were deionized water, 500 ppm fluoride solution, and the gold standard rinse in the field (Sn2+/F-). In total, 135 enamel specimens (n=15/group) were subjected to five cycles of salivary pellicle formation (30 min, 37°C), modification with the solutions (2 min, 25°C), further salivary pellicle formation (60 min, 37°C), and erosive challenge (1 min, 1% citric acid, pH 3.6). Relative surface microhardness (rSMH), surface reflection intensity (rSRI), and amount of calcium release (CaR) were investigated. Data were analyzed with Kruskal-Wallis and Wilcoxon rank sum tests (α=0.05). Results The polyphenol solutions containing fluoride, as well as additional flavors, protected enamel better than fluoride alone, and similar to the Sn2+/F- solution, when investigating both rSMH and CaR. When measuring rSRI, Sn2+/F- showed the best protection, while the polyphenol solutions were similar to fluoride. Conclusion For two of the three assessed parameters (rSMH and CaR), both developed polyphenol-rich rinsing solutions were able to protect enamel from erosion, improving/potentializing the effect of fluoride and matching the protection offered by the current gold standard rinsing solution.

Abstract Controversial results showing that deciduous teeth are more susceptible to erosion than permanent teeth might be related to study designs. We investigated how different conditions (pH: 3.0, 4.0, 5.0; acid agitation: gentle or vigorous; acid exposure times: 1–5 min) affect the susceptibility of both teeth to erosion. Enamel specimens (90 deciduous, 90 permanent) were distributed into groups (n = 15 permanent, n = 15 deciduous) according to acid pH (pH 5, 4 or 3) and agitation (gentle or vigorous) during erosive challenge. Both milder (less incubation time, gentle agitation, and higher pH) and more severe (longer incubation times, vigorous shaking, and lower pH) conditions were used. Demineralization was measured by relative surface microhardness (rSMH) and calcium released to the acid. Demineralization increased gradually for both teeth with increasing incubation time, agitation (gentle or vigorous), and with decreasing acid pH. The differences between deciduous and permanent teeth depended on the protocol design and assessment method. Under milder conditions, demineralization was better detectable with rSMH. Under more severe conditions, differences were more perceptible with calcium analyses. Differences exist in the susceptibility to erosion between deciduous and permanent teeth, but they are only distinguishable when the appropriate assessment method is used for the specific erosive condition.

Introduction: This consensus paper provides recommendations for oral health professionals on why and how to assess caries activity and progression with special respect to the site of a lesion. Methods: An expert panel was nominated by the executive councils of the European Organization for Caries Research (ORCA) and the European Federation of Conservative Dentistry (EFCD). The steering committee built three working groups that were asked to provide recommendations on (1) caries detection and diagnostic methods, (2) caries activity and progression assessment, and (3) obtain individualized caries diagnoses. The experts of work group 2 phrased and agreed on provisional general and specific recommendations on caries lesion activity and progression, based on a review of the current literature. These recommendations were then discussed and refined in a consensus workshop followed by an anonymous Delphi survey to determine the agreement on each recommendation. Results: The expert panel agreed on general (n = 7) and specific recommendations (n = 6). The specific recommendations cover coronal caries on pits and fissures, smooth surfaces, proximal surfaces, as well as root caries and secondary caries/caries adjacent to restorations and sealants. 3/13 recommendations yielded perfect agreement. Conclusion: The most suitable method for lesion activity assessment is the visual-tactile method. No single clinical characteristic is indicative of lesion activity; instead, lesion activity assessment is based on assessing and weighing several clinical signs. The recall intervals for visual and radiographic examination need to be adjusted to the presence of active caries lesions and recent caries progression rates. Modifications should be based on individual patient characteristics. [ABSTRACT FROM AUTHOR]

Objectives: The aim of the present consensus paper was to provide recommendations for clinical practice on the individual etiological and modifying factors to be assessed in the individual diagnosis of caries, and the methods for their assessment, supporting personalized treatment decisions. Material and Methods: The executive councils of the European Organisation for Caries Research (ORCA) and the European Federation of Conservative Dentistry (EFCD) nominated ten experts each to join the expert panel. The steering committee formed three work groups which were asked to provide recommendations on (1) caries detection and diagnostic methods, (2) caries activity assessment, and (3) forming individualized caries diagnoses. The experts responsible for "individualised caries diagnosis" searched and evaluated the relevant literature, drafted this manuscript and made provisional consensus recommendations. These recommendations were discussed and refined during the structured process in the whole work group. Finally, the agreement for each recommendation was determined using an anonymous eDelphi survey. The threshold for approval of recommendations was determined at 70% agreement. Results: Ten recommendations were approved and agreed by the whole expert panel, covering medical history, caries experience, plaque, diet, fluoride, and saliva. While the level of evidence was low, the level of agreement was typically very high, except for one recommendation on salivary flow measurement, where 70% agreed. Conclusion: It is recommended that all aspects of caries lesion progression and activity, recent caries experience, medical conditions and medications, plaque, diet, fluoride and saliva should be synthesized to arrive at an individual diagnosis. Clinical Relevance: The expert panel merged evidence from existing guidelines and scientific literature with practical considerations and provided recommendations for their use in daily dental practice.

Twin‐to‐twin transfusion syndrome (TTTS) is a severe disorder that often leads to the death of monochorionic twin fetuses, if left untreated. Current prenatal interventions to treat the condition involve the use of rigid fetoscopes for targeted laser coagulation of the vascular anastomoses. These tools are limited in their area of operation, making treatment challenging, especially in cases with anterior placentation. Herein, a robotic platform to perform this task using remote magnetic navigation is proposed. In contrast to rigid tools, the presented custom magnetic fetoscope is highly flexible, dexterous, and has considerable advantages, including safety and precision. A visual servoing algorithm that allows the surgeon to navigate in the uterus with submillimeter precision is introduced. The system has been validated on ex vivo human placentas in a setting that mimics the real intraoperative conditions.

Abstract The objective of this study was to explore the relationship between intrinsic and extrinsic factors and a high cumulative score of the Basic Erosive Wear Examination (BEWE) in a Chilean adult group. A cross-sectional study was performed with the Ethics Committee’s approval from the Universidad de los Andes. A consecutive adult (18 to 46 years old) sampling (n = 553) from the Health Center in San Bernardo-Chile, was selected from September 2016 to January 2017. Dental exams were performed by two trained and calibrated examiners, according to the BEWE index. In order to search for potentially related factors, a hetero-applied questionnaire previously developed and evaluated was applied. Our interest was individuals with severe erosion tooth wear (BEWE ≥ 14). Logistic regression models reporting crude odds ratio (OR) and adjusted OR by age, 95% confidence interval (95%CI), and p-values were estimated. Variables, odds ratios and 95% CI related with BEWE ≥ 14 were: age (OR 1.1 [1.07–1.14]); currently drinking alcohol (OR 1.59 [1.06-2.39]); esophagitis (OR 8.22 [1.60–42.22]); difficulty to swallow (OR 2.45 [1.10–5.44]); chest pain (OR 2.07 [1.18–3.64]); anorexia (OR 3.82 [1.07–13.68]); vitamin C intake (OR 1.92 [1.08–3.43]). Age, alcohol consumption, self-reported esophagitis, history of gastric symptoms, anorexia, and vitamin C intake were related as risk factors to high BEWE scores in this sample of Chilean adults in San Bernardo, Chile.

Este artigo visa refletir sobre a potência de ações e serviços no campo da Saúde Mental no sistema de saúde pública brasileira, com o intuito de fomentar práticas emancipatórias, sobretudo no contexto de retrocessos vivenciados com a atual Nova Política Nacional de Saúde Mental, que se contrapõe aos preceitos da Reforma Psiquiátrica. Ancoradas em elementos teóricos acerca da emancipação, da sociologia das ausências e da sociologia das emergências, discutimos os grupos de ajuda e suporte mútuos, os grupos de ouvidores de vozes, os centros de convivência e as iniciativas de Economia Solidária, os quais visam à superação da lógica da monocultura do saber, valorizando o conhecimento dos usuários e adotando práticas horizontalizadas e autogestionárias. Tais experiências precisam ser sistematizadas, vivenciadas e multiplicadas para que seja possível o desenvolvimento de redes de cuidado com potencial emancipatório.
