Patient research partner engagement in OMERACT: Enhancing engagement through the implementation of patient engagement in research tools.

OBJECTIVES: This paper describes the evolution and impact of Patient Research Partners (PRPs) in shaping research within OMERACT and provides a framework to enhance their engagement. This session explored one component of a validated framework to evaluate meaningful patient engagement. It provides insights, identifies opportunities for improvement, and recommends using the Patient Engagement in Research (PEIR) Framework, PEIR Plan Guide (workbook), and PEIRS-22 (scale) to guide and measure PRPs' engagement. METHODS: Before the conference, the team held planning sessions and selected the Feel-Valued component of the PEIR Workbook for exploration. During OMERACT 2023, we discussed this topic using the PEIR Plan Guide in an interactive plenary session. RESULTS: The plenary session produced 72 items from 14 breakout tables addressing PEIR Framework themes. CONCLUSIONS: This paper highlights the role and evolution of PRPs in shaping research within OMERACT. It emphasizes enhancing and accurately measuring PRP engagement through the PEIR Framework, PEIR Plan Guide, and PEIRS-22. The insights and methodologies presented aim to fortify future PRP engagement, ensuring it aligns with OMERACT's principles of patient-centred research.

Pre-eruptive intracoronal resorption in orthodontic patients: A retrospective analysis of 3,143 patients.

Objectives: The aim of this retrospective study was to analyze the occurrence and characteristics of pre-eruptive intracoronal resorptions in a clinical orthodontic patient population. Materials and methods: Patients treated in an orthodontic department (University of Pécs, Pécs, Hungary) were included. Unerupted teeth on panoramic radiographs were analyzed for intracoronal radiolucent lesions. For each patient, the demographic data, jaw localization, number of unerupted teeth with pre-eruptive intracoronal resorption lesions, number of lesions per tooth, size and localization of pre-eruptive intracoronal resorption defects, affected tooth's surface, pulp involvement and ectopic position of the tooth with defects were recorded. Results: In the 3,143 patients investigated, 55 teeth in 49 patients showed pre-eruptive intracoronal resorption lesions (subject incidence: 1.56%). The incidence on unerupted teeth was 0.25%. Pre-eruptive intracoronal resorption was significantly more common in mandibles (43 mandibular vs. 12 maxillary lesions) with an odds ratio of 12.84 (95% Confidence Interval: 5.19-31.74) and no gender differences were found (p = 0.746). The occurrence of pre-eruptive intracoronal resorption was highest in the youngest (7-10 years) mixed dentition status group (p < 0.001). Most of the lesions (44 of 55, or 80.0%) were localized in the dentin, occupying two-third or less of the dentin thickness. Only 12.73% (7/55) of the lesions were not localized on the occlusal surface. Of the lesions, 89.1% (49/55) showed no obvious size increase over an average follow-up of 36.4 ± 8.1 months. Conclusions: Pre-eruptive intracoronal resorption may occur mainly in the mixed dentition stage in orthodontic patients. Careful and attentive radiographic evaluations may facilitate early detection and follow-up of the lesions' possible dimensional changes, especially when resorption influences orthodontic extraction therapy.

Persisting embryonal infundibular recess (PEIR) and transsphenoidal-transsellar encephaloceles: distinct entities or constituents of one continuum?

Persisting embryonal infundibular recess (PEIR) is a very rare anomaly of the floor of the third ventricle in which the embryonic morphology of the infundibular recess (IR) persists. The exact underlying mechanism of development of PEIR is unknown, and the anomaly has been reported as an isolated finding or in association with other conditions. On the other hand, trans-sphenoidal encephaloceles are the rarest form of basal encephaloceles. The trans-sphenoidal trans-sellar encephalocele (TSE) is the least common variant in which the pituitary gland, pituitary stalk, optic pathways, parts of the third ventricle and IR may be present within the encephalocele. We recently treated one patient with TSE. Based on the observed morphological similarity of the IR in our patient and in the published cases of PEIR, we reviewed the literature in order to validate the hypothesis that PEIR and TSE may possibly belong to one spectrum of malformations. Across the published reports, the morphology of the IR in TSE is very closely similar to PEIR. Moreover, radiological, patho-anatomical, and embryological evidence is in support to our hypothesis that PEIR and TSE are most likely the two extremes of the same continuum of malformations.

A 3000 year old case of an unusual dental lesion: Pre-eruptive intracoronal resorption.

OBJECTIVE: To determine the cause of a large dental lesion, tentatively identified as a case of pre-eruptive intra-coronal resorption (PEIR), in the permanent second mandibular molar of a young individual from an Iron Age cemetery at Tel Erani (Israel), dated to ca. 3000 years B.P. The provisional diagnosis was based on the massive size of the lesion in a young individual in whom the adjacent teeth were caries-free and showed no visible enamel defects. DESIGN: The lower molars of Tel Erani on the affected side were radiographed and compared to radiographs of a modern clinical case of PEIR treated by one of us (U.Z) and the internal structure and mineral content of the lesion examined in detail using energy-dispersive X-ray spectroscopy (EDS). RESULTS: The Tel Erani specimen closely resembled the modern clinical case of PEIR. Moreover, both cases occurred in young individuals in whom the adjacent teeth were caries-free. Examination with SEM revealed absence of dentine in the affected tooth from Tel Erani, together with changes in structure and mineral content characteristic of resorption. CONCLUSIONS: Our study shows that the changes found in the lower second molar of the 3000 year old mandible from Tel Erani are characteristic of PEIR and demonstrate the antiquity of this condition.

Uma contribuição da metodologia Peir para o estudo de uma pequena cidade na Amazônia: Ponta de Pedras, Pará / A contribution from the DPSIR methodology to the study of a small town in the Amazon: Ponta de Pedras, Pará, Brazil

Resumo Este artigo objetivou analisar a contribuição da metodologia Peir para estudo de uma pequena cidade da Amazônia a partir da análise do modo de vida da população. Como procedimento metodológico procurou-se entender a relação entre aspectos de urbanização conectados à globalização e saúde da população dessa cidade. Foram obtidos dados em campo, os quais permitiram analisar a situação de saúde em dois setores urbanos. A metodologia Pressão-Estado-Impacto-Resposta (Peir), desenvolvida pelo Programa das Nações Unidas para o Meio Ambiente (Pnuma) e adaptada pela Organização para a Cooperação e Desenvolvimento Econômico (OCDE), servirá de suporte para a compreensão dos impactos na saúde da população a partir do acesso a infraestruturas disponíveis, entre elas o abastecimento de água. O local de estudo é cidade de Ponta de Pedras, situada na Ilha do Marajó, estado do Pará, Brasil. Como resultado nota-se a necessidade de intervenções imediatas por parte do poder público para minimizar os impactos das condições de vulnerabilidade sobre as populações.

Abstract This article aimed to analyze DPSIR approach's contribution in an Amazonian small town, according to the local people's lives. As methodological procedure, we sought to understand the relation between urbanization aspects connected to globalization and the population health of said small town. For this research, data were obtained in field, which allowed an analysis of the health situation in two urban sectors. The DPSIR methodology - Driving force-Pressure-State-Impact-Response, developed by United Nations Environment (UNE) and adapted by the Organization for Economic Cooperation and Development (OECD), will serve as support for the understanding of impacts on the population's health, analyzing issues as access to available infrastructure, including water supply. As a result, Ponta de Pedras town, located in Marajó Island (PA), Brazil - where the research was performed -, requires an immediate intervention from the public authorities to minimize impacts of population's exposure to vulnerable conditions.

Intracellular disassembly and localization of a new P123-PEI-R13/DNA complex.

The appropriate location and release of target gene is necessary for gene therapy. In our previous paper, a gene vector named P123-PEI-R13 has been successfully synthesized, and the physical characteristics and cellular trafficking of nanoparticle P123-PEI-R13/DNA has been explored explicitly, but little was known about its disassembly within cells. In order to investigate its intracellular disassembly, P123-PEI-R13/DNA complex was exposed to the different competitors (RNA, DNA, proteins) or different conditions of pH and osmolarity, DNA release was determined by gel electrophoresis. Meanwhile, confocal laser technology was used to locate the complex in cells. The results revealed that DNA, RNA and osmolarity could affect the stability of the complex obviously, especially RNA which exist in nucleus. In addition, the speed of DNA release decreased as the weight ratio of polymer increased. Images got by a confocal fluorescence microscope confirmed that after cell uptake, P123-PEI-R13 could translocate DNA into nucleus.
