Objectives: This study aimed to assess membrane use with a bone substitute graft for guided bone regeneration (GBR) in experimental dehiscence defects. Materials and methods: Maxillary second incisors (I2) in 9 dogs were extracted. Six weeks later, implants were inserted and experimental dehiscence defects (5 × 3 mm) created on the buccal aspect. The defects and surrounding bone were grafted with deproteinized bovine bone mineral. One side (test) was covered with a resorbable collagen membrane whereas the contralateral side (control) was not. After 6 weeks, histomorphometrical analysis was performed to evaluate: (a) first bone-to-implant contact (fBIC), (b) buccal bone thickness at 1 mm increments from implant shoulder, (c) regenerated area (RA), (d) area and percentages of new bone (B), bone substitute (BS) and mineralized tissue (MT). Results: The histological appearance was similar between test and control sites. At central and lateral sections, there were no differences between groups for fBIC, buccal bone thickness, RA, BS, B, %B, MT and %MT. At central sections, membrane use favoured more %BS and %MT (p = 0.052). There was significantly more B, %B and MT at lateral compared to central sections. Conclusions: Membrane use tended to retain more bone substitute, but had no effect on new bone ingrowth. Lateral sections showed significantly more bone ingrowth and mineralized tissue compared to central sections, confirming that new bone ingrowth takes place mainly from the lateral walls of the defect. Clinical relevance: Preclinical research to clarify the dynamics of bone regeneration in GBR procedures is relevant in clinical practice. [ABSTRACT FROM AUTHOR]

Autism health passports (AHPs) have been endorsed by the UK government and recommended by the National Institute for Health and Care Excellence, but are they working in practice? As autistic researchers, we want to share what we have discovered. [ABSTRACT FROM AUTHOR]

This article describes and reflects on the first six meetings of a newly established Autistic community council, founded to steer a participatory, longitudinal qualitative study investigating the reproductive health of Autistic people with wombs. The two key aims of these initial six meetings – involving four Autistic community leader members and three Autistic researchers – was to (1) guide the start of the project and the development of accessible recruitment materials for the future eight lay members and (2) establish a safe space and a model of accessible communication. We draw on extracts from transcripts made during meetings, member ‘field’ notes and a reflexive co-writing practice to identify the ways in which a sense of safety was built during these first community council meetings. We explore what it means to be an insider-only Community Partnered Participatory Research Council and reflect on the praxis we developed to facilitate Autistic knowledge production.In recent years, there has been a growing call for participatory Autism research (i.e. research that meaningfully involves Autistic people in its design and delivery). Community Partnered Participatory Research is a research methodology that aims to share power between researchers and members of the researched community. There is some precedent for Community Partnered Participatory Research in Autism research, but it is still quite uncommon. At the start of our new research study (called Autism: From Menstruation to Menopause), we created a community council. For the first six meetings, our council was made up of four Autistic community members who were experienced in Autism advocacy and activism and three Autistic researchers. We seven are the authors of this article. In these first six meetings, we made plans for recruiting a larger number of lay community members who would join us later for the rest of the project (8 years in total). In this article, we describe and reflect what it felt like during these first six meetings to be part of a community research council where everybody is Autistic. We discuss how we co-created a safe space, how we helped each other feel valued and how we worked together to support each other’s sometimes-differing access needs so that everyone could fully participate. We provide recommendations for how to support Autistic people to lead research on their own terms with their unique insights. [ABSTRACT FROM AUTHOR]

Given the various sources and consequences of opioid use disorder (OUD) stigma, the mechanisms by which stigma occurs becomes more important. Educational deficits regarding OUD as a disease and treatment influence OUD stigma. The purpose of the study was to develop, pilot test and psychometrically evaluate the Opioid-Knowledge (O-Know) test in a community setting. A social media strategy was used to recruit 294 participants, in 2019, from a midwestern region experiencing an HIV epidemic, stemming from opioid and injection drug use. The Factor analysis used a tetrachoric correlation matrix, with principal axis factor extraction and Promax rotation. Horn's parallel analysis supported the factorial validity of a two-factor model representing OUD as a Disease (Cronbach's alpha =.57) and OUD Treatment and Recovery (Cronbach's alpha =.62). The reliability estimates were deemed adequate given the intended group-level uses for the instrument. Convergent construct validity was partially supported via the OUD Treatment and Recovery factor's negative correlation with personal opioid stigmatization (B = −.29, p =.001). OUD research must produce measures that convert observations to empirical generalizations. The psychometric analysis of the O-Know scale demonstrated progress in reducing measurement error to facilitate that conversion. [ABSTRACT FROM AUTHOR]

Background: Autistic people are more likely to experience stigma, communication barriers and anxiety during healthcare. Autism Health Passports (AHPs) are a communication tool that aim to provide information about healthcare needs in a standardised way. They are recommended in research and policy to improve healthcare quality. Aim: To explore views and experiences of AHPs among Autistic people from the UK who have been pregnant. Methods: We developed an online survey using a combination of open and closed questions focused on healthcare impairments and views and experiences of AHPs. Data were anlaysed using descriptive statistics, Kruskal-Wallis tests, and content analysis. Findings: Of 193 Autistic respondents (54% diagnosed, 22% undergoing diagnosis and 24% self-identifying), over 80% reported anxiety and masking during healthcare always or most of the time. Some significant differences were identified in healthcare (in)accessibility by diagnostic status. Only 4% of participants knew a lot about AHPs, with 1.5% of participants using one at least half of the time. Almost three quarters of respondents had not previously seen an AHP. Open text responses indicated that the biggest barrier to using an AHP was a belief that health professionals would discriminate against Autistic patients. Additional barriers included staff lack of familiarity with AHPs and respondents expecting a negative response to producing an AHP. Conclusions: Our findings suggest that AHPs are not reducing health inequalities for Autistic adults who have been pregnant. Alternative solutions are needed to reduce health inequalities for Autistic people. [ABSTRACT FROM AUTHOR]

Introduction: Newly developed wearable fabric sensors (WFS) can increase the ease and accuracy of sweat sodium measurements by performing simultaneous sampling and analysis on the body during exercise. Purpose: Determine the accuracy of a WFS for measurement of sodium concentration in sweat. METHODS: Subjects wore a WFS prototype and sweat collectors on their forearm during cycle ergometry. Subjects exercised at a moderate intensity (~ 65% heart rate reserve) for 30–60 min. Sweat samples were collected and analyzed using a commercial sweat sodium analyzer (SSA) every 10–15 min. WFS were adhered with an armband and connected to custom built electronics. Accuracy was determined by comparing predicted WFS concentration to the actual concentration from the commercial SSA and analyzed statistically using ANOVA and Bland−Altman plots. Results: A total of 19 subjects completed the study. The average sweat sodium concentration was 59 mM ± 22 mM from a SSA compared with 54 mM ± 22 mM from the WFS. Overall, the average accuracy of the WFS was 88% in comparison to the SSA with p = 0.45. A line of best fit comparing predicted versus actual sweat sodium concentration had a slope of 0.99, intercept of – 4.46, and an r2 of 0.90. Bland−Altman analysis showed the average concentration difference between the WFS and the SSA was 5.35 mM, with 99% of data points between ± 1.96 times the standard deviation. Conclusion: The WFS accurately predicted sweat sodium concentration during moderate intensity cycle ergometry. With the need for precise assessment of sodium loss, especially during long duration exercise, this novel analysis method can benefit athletes and coaches. Further research involving longer duration and more intense exercise is warranted. [ABSTRACT FROM AUTHOR]

Background: Managing medications for Alzheimer's disease and related dementias is challenging for caregivers. Information about caregivers' strategies to manage these challenges is needed to inform intervention development. Objective: This study aimed to understand caregivers' medication management experiences by analyzing online community discussions. Methods: Posts were extracted from the ALZConnected® Forum using keywords "medication" and "drug" via web scraping. The researchers applied thematic analysis. Results: Four major themes emerged: (1) role transition of medication management responsibilities, (2) caregivers' uncertainty about medication purpose and values, (3) conflicts between the care recipients and caregivers, and (4) difficulty accessing and affording medications. Conclusions: The experiences shared on a non-moderated, unstructured online forum indicate that medication management is challenging and overwhelming for caregivers of people living with Alzheimer's disease and related dementias. Since this is a progressive disease with various stages and changing needs, caregivers' strategies vary and are often limited by available resources and support. Health care providers should offer training and support for caregivers to navigate the transfer of medication management responsibilities and changing care needs as the disease progresses.

Participatory research approaches hold potential to better understand society through valuing lived experience. Formula feeding babies is routinely stigmatised in the UK, despite inadequate support to facilitate breastfeeding. Our community science project investigated the safety of powdered infant formula preparation in the home through the completion of an at-home experiment and a research diary with closed and open questions (n = 151). To add validity to the interpretation of open text data in research diaries, a community analysis group of five formula-feeding mothers was established. The community analysts undertook inductive thematic analysis through a series of analysis group meetings focused around data extracts, contributed to the study's empirical outputs and this methodological output, meeting 23 times over a nine-month period. Detailed notes were taken during meetings and the methodological elements of these were thematically analysed with the community analysts to produce this article, with extracts from the academic researchers' field notes added where relevant. The overarching themes, presenting both positive experiences and areas for improvement, focused on: (i) clarity of expectations and the impact this had on community analysts' confidence, (ii) the stigmatising topic area and how this was managed by the facilitators, and (iii) feeling valued, in relation to honoraria, inclusion in outputs and community analysts coming to recognise their own expertise. Furthermore, the community analysts co-produced recommendations for including community analysts in future research. It provides guidance on how this can be appropriately costed for and supported by funding bodies and research teams, as well as providing guidance on recruitment and chairing meetings. We hope that this article can provide valuable input into how to involve the community more inclusively as research partners in qualitative analysis related to stigmatised topics.

Formula fed infants experience gastrointestinal infections at higher rates than breastfed infants, due in part to bacteria in powdered infant formula (PIF) and bacterial contamination of infant feeding equipment. The United Kingdom National Health Service (UK NHS) has adopted the World Health Organization recommendation that water used to reconstitute PIF is ≥70°C to eliminate bacteria. We used community science methods to co‐design an at home experiment and online questionnaire ('research diary') to explore the safety of PIF preparation compared to UK NHS guidelines. 200 UK‐based parents of infants aged ≤12 months were recruited; 151 provided data on PIF preparation, and 143 were included in the analysis of water temperatures used to reconstitute PIF. Only 14.9% (n = 11) of 74 PIF preparation machines produced a water temperature of ≥70°C compared with 78.3% (n = 54) of 69 kettle users (p < 0.001). The mean temperature of water dispensed by PIF preparation machines was 9°C lower than kettles (Machine M = 65.78°C, Kettle M = 75.29°C). Many parents did not always fully follow NHS safer PIF preparation guidance, and parents did not appear to understand the potential risks of PIF bacterial contamination. Parents should be advised that the water dispensed by PIF preparation machines may be below 70°C, and could result in bacteria remaining in infant formula, potentially leading to gastrointestinal infections. PIF labelling should advise that water used to prepare PIF should be ≥70°C and highight the risks of not using sufficiently hot water, per WHO Europe advice. There is an urgent need for stronger consumer protections regarding PIF preparation devices. Key points: Only 14.9% (n = 11) of 74 PIF preparation machines produced a water temperature of ≥70°C compared with 78.3% (n = 54) of 69 kettle users (p < 0.001).The mean temperature of water dispensed by PIF preparation machines was 9°C lower than kettles (Machine M = 65.78°C, Kettle M = 75.29°C).Most parents routinely washed and sterilised bottles and teats.Many parents did not always fully follow NHS safer PIF preparation guidance, including 21.8% washing their hands half the time or less, and 14.6% regularly pre‐preparing bottles.Most parents did not appear to understand the risks of PIF bacterial contamination.
