Lean body mass in living kidney donors impacts postoperative renal function. World J Urol 2024; 42:214. [PMID: 38581460 PMCID: PMC10998768 DOI: 10.1007/s00345-024-04908-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2024] [Accepted: 02/26/2024] [Indexed: 04/08/2024] Open
Abstract
PURPOSE A living donor kidney transplant is the optimal treatment for chronic renal impairment. Our objective is to assess if lean skeletal muscle mass and donor factors such as body mass index, hypertension, and age impact on renal function following donor nephrectomy. METHODS Potential donors undergo CT angiography as part of their work-up in our institution. Using dedicated software (Horos®), standardized skeletal muscle area measured at the L3 vertebrae was calculated. When corrected for height, skeletal muscle index can be derived. Skeletal muscle mass index below predefined levels was classified as sarcopenic. The correlation of CT-derived skeletal muscle index and postoperative renal function at 12 months was assessed. Co-variables including donor gender, age, body mass index (BMI), and presence of pre-op hypertension were also assessed for their impact on postoperative renal function. RESULTS 275 patients who underwent living donor nephrectomy over 10 years were included. Baseline pre-donation glomerular filtration rate (GFR) and renal function at one year post-op were similar between genders. 29% (n = 82) of patients met the criteria for CT-derived sarcopenia. Sarcopenic patients were more likely to have a higher GFR at one year post-op (69.3 vs 63.9 mL/min/1.73 m2, p < 0.001). The main factors impacting better renal function at one year were the presence of sarcopenia and younger age at donation. CONCLUSION When selecting donors, this study highlights that patients with low skeletal mass are unlikely to underperform in terms of recovery of their renal function postoperatively at one year when compared to patients with normal muscle mass and should not be a barrier to kidney donation.

Psychosocial factors, dentist-patient relationships, and oral health-related quality of life: a structural equation modelling. Health Qual Life Outcomes 2023; 21:130. [PMID: 38049808 PMCID: PMC10696761 DOI: 10.1186/s12955-023-02214-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 11/27/2023] [Indexed: 12/06/2023] Open
Abstract
BACKGROUND Psychosocial factors and dentist-patient relationships (DPR) have been suggested to be associated with oral health outcomes. This study aimed to test a conceptual model which hypothesised relationships among psychosocial factors, DPR variables, and oral health-related quality of life (OHRQoL) in the 'distal-to-proximal' framework. METHODS A total of 12,245 adults aged 18 years or over living in South Australia were randomly sampled for the study. Data were collected from self-complete questionnaires in 2015-2016. The outcome variable of Oral Health Impact Profile was used to measure OHRQoL. Psychosocial domain consisted of psychological well-being, social support, and health self-efficacy. DPR domain included trust in dentists, satisfaction with dental care, and dental fear. The hypothesised model was tested using the two-step approach in structural equation modelling. RESULTS Data were analysed from 3767 respondents after the screening/preparing process (adjusted valid response rate 37.4%). In the first step of the analysis, confirmatory factor analyses produced acceptable measurement models for each of the six latent variables (GFI = 0.95, CFI = 0.98, RMSEA = 0.04). The final structural model indicated that better well-being, higher self-efficacy, and more satisfaction were associated with lower oral health impact (β = - 0.12, - 0.07, - 0.14, respectively) whereas fear was positively associated (β = 0.19). Among intermediates, support was positively associated with satisfaction within a small effect size (β = 0.06) as compared to self-efficacy with trust (β = 0.22). The invariance of the final model was also confirmed on participants' SES and dental service characteristics except the variable of 'last dental visit'. CONCLUSIONS Psychosocial factors and DPR variables were associated with oral health impact in both direct and indirect paths. The framework of 'distal-to-proximal' actions is empirically supported from psychosocial factors via DPR variables to OHRQoL.

The impact of the COVID-19 pandemic on the provision of endovascular thrombectomy for stroke: an Irish perspective. Ir J Med Sci 2023; 192:3073-3079. [PMID: 36792763 PMCID: PMC9931560 DOI: 10.1007/s11845-023-03314-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Accepted: 02/08/2023] [Indexed: 02/17/2023]
Abstract
BACKGROUND The COVID-19 pandemic produced unprecedented challenges to healthcare systems. These challenges were amplified in the setting of endovascular thrombectomy (EVT) for large vessel occlusion strokes given the time-sensitive nature of the procedure. AIMS To assess the impact of the COVID-19 pandemic on service provision at the primary endovascular stroke centre in Ireland. METHODS A retrospective review of the National Thrombectomy Service database was performed. All patients undergoing EVT from 1 January to 31 December inclusive of 2019 to 2021 were included. Patient demographics, functional outcomes and endovascular treatment time metrics were recorded. RESULTS Data from 2019, 2020 and 2021 were extracted. Three hundred seven thrombectomies were performed in 2019 and 2020; this number increased to 327 in 2021. Median time from arrival to groin puncture for thrombectomy was 64 min in 2019, increasing to 65 min in 2020. In 2021, this decreased to 52 min. Median time taken from groin puncture to first perfusion remained stable from 2019 to 2021 years at 20 min. Total duration of emergency thrombectomies reduced from 32 min in 2019 to 27 min in 2020. This increased to 29 min in 2021. CONCLUSIONS Despite the myriad of challenges presented by the pandemic, service provision at the primary Irish ESC, and the referring hospitals, has proven to be robust. Procedural time metrics were maintained whilst the expected reduction in number of EVTs performed did not materialise, there actually being a significant increase in number of EVTs performed in the pandemic's second year.

Abstract
Major depressive disorder (MDD) is associated with biased perception of human movement. Gesture is important for communication and in this study we investigated neural correlates of gesture perception in MDD. We hypothesised different neural activity between individuals with MDD and typical individuals when viewing instrumental and expressive gestures that were negatively or positively valenced. Differences were expected in brain areas associated with gesture perception, including superior temporal, frontal, and emotion processing regions. We recruited 12 individuals with MDD and 12 typical controls matched on age, gender, and handedness. They viewed gestures displayed by stick figures while functional magnetic resonance imaging (fMRI) was performed. Results of a random effects three-way mixed ANOVA indicated that individuals with MDD had greater activity in the right claustrum compared to controls, regardless of gesture type or valence. Additionally, we observed main effects of gesture type and valence, regardless of group. Perceiving instrumental compared to expressive gestures was associated with greater activity in the left cuneus and left superior temporal gyrus, while perceiving negative compared to positive gestures was associated with greater activity in the right precuneus and right lingual gyrus. We also observed a two-way interaction between gesture type and valence in various brain regions.

Abstract
OBJECTIVES This study aimed to estimate the effects of positive personality traits (PTs) in income and self-rated dental and general health (SRDH and SRGH) associations in a large South Australian sample. METHODS Cross-sectional analyses were conducted using self-reported data collected from 3578 adults (2015-2016). Multivariable regression models assessed the main effects and interactions of the Ten-Item Personality Inventory (TIPI) and income with SRDH and SRGH. Prevalence ratios (PR) of poor health ratings were estimated using Poisson regression. RESULTS Among all respondents, high-income individuals with stronger Conscientiousness scores had the lowest prevalence of poor SRGH (0.8%), while those with stronger Extraversion (2.9%) and Agreeableness scores (3.4%) had the lowest prevalence of poor SRDH. Poor SRGH was related to weak Conscientiousness (PR = 6.9, 95% CI [2.3-20.8]) and Emotional Stability scores (PR = 6.0, 95% CI [2.0-18.3]), while poor SRDH was associated with weak Extraversion (PR = 2.3, 95% CI [1.2-4.5]), Agreeableness (PR = 1.8, 95% CI [1.0-3.2]) and Conscientiousness scores (PR = 2.1, 95% CI [1.1-4.0]). Among low-income people, poor health ratings were less prevalent in those with stronger positive PTs scores versus weaker scores. Among low-income respondents, poor SRGH was lower in individuals with stronger versus weaker Conscientiousness scores (10.9% vs 16.2%), and poor SRDH showed lower prevalence in participants with stronger versus weaker Agreeableness scores (18.1% vs 22.6%). CONCLUSION Findings showed the association between PTs and the prevalence of poor SRDH and SRGH. Stronger positive PTs modified the self-rated health inequalities associated with low income in a representative sample of the South Australian population.

Effect of Different Frequencies of Dental Visits on Dental Caries and Periodontal Disease: A Scoping Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:6858.

Abstract
Recommending dental visits every six months is commonplace among dental practitioners worldwide. A scoping review was conducted by electronically searching PubMed, Scopus and Embase to identify and map the nature of evidence for the effect of different frequencies of dental visits on dental caries and periodontal disease. Studies were written in English on the frequency of dental visits and published between January 2008 and April 2023. Three systematic reviews that evaluated the risk of bias, strength of studies and certainty of evidence were included from the 4537 articles yielded through the search strategy. The available evidence was weak and of low quality for the currently recommended frequencies of dental visits, whether these are fixed or universal. For adults, there was little to no effect of making biannual, biennial or risk-based dental visits on dental caries and periodontal disease, which was supported by moderate- to high-certainty evidence. Accordingly, it is suggested that dental professionals and dental insurance providers make individually tailored, customised and risk-based recommendations for dental visits, rather than encouraging fixed or universal frequencies of dental visits. For children and adolescents, further research on this issue warrants well-designed randomised controlled trials (RCTs) and cohort studies of sufficient duration with an adequate number of participants.

Abstract
Supplementary motor area (SMA) syndrome is characterised by transient disturbance in volitional movement and speech production which classically occurs after injury to the medial premotor area. We present two cases of SMA syndrome following isolated surgical injury to the frontal aslant tract (FAT) with the SMA intact. The first case occurred after resection of a left frontal operculum tumour. The second case occurred after a transcortical approach to a ventricular neurocytoma. The clinical picture and fMRI activation patterns during recovery were typical for SMA syndrome and support the theory that the FAT is a critical bundle in the SMA complex function.

Abstract
Immune checkpoint inhibitors (ICIs) have rejuvenated therapeutic approaches in oncology. Although responses tend to be durable, response rates vary in many cancer types. Thus, the identification and validation of predictive biomarkers is a key clinical priority, the answer to which is likely to lie in the tumour microenvironment (TME). A wealth of data demonstrates the huge impact of the TME on ICI response and resistance. However, these data also reveal the complexity of the TME composition including the spatiotemporal interactions between different cell types and their dynamic changes in response to ICIs. Here, we briefly review some of the modalities that sculpt the TME, in particular the metabolic milieu, hypoxia and the role of cancer-associated fibroblasts. We then discuss recent approaches to dissect the TME with a focus on single-cell RNA sequencing, spatial transcriptomics and spatial proteomics. We also discuss some of the clinically relevant findings these multi-modal analyses have yielded.

Abstract
CD39 (ENTPD1) is a key enzyme responsible for degradation of extracellular ATP and is upregulated in the tumor microenvironment (TME). Extracellular ATP accumulates in the TME from tissue damage and immunogenic cell death, potentially initiating proinflammatory responses that are reduced by the enzymatic activity of CD39. Degradation of ATP by CD39 and other ectonucleotidases (e.g., CD73) results in extracellular adenosine accumulation, constituting an important mechanism for tumor immune escape, angiogenesis induction, and metastasis. Thus, inhibiting CD39 enzymatic activity can inhibit tumor growth by converting a suppressive TME to a proinflammatory environment. SRF617 is an investigational, anti-CD39, fully human IgG4 Ab that binds to human CD39 with nanomolar affinity and potently inhibits its ATPase activity. In vitro functional assays using primary human immune cells demonstrate that inhibiting CD39 enhances T-cell proliferation, dendritic cell maturation/activation, and release of IL-1β and IL-18 from macrophages. In vivo, SRF617 has significant single-agent antitumor activity in human cell line-derived xenograft models that express CD39. Pharmacodynamic studies demonstrate that target engagement of CD39 by SRF617 in the TME inhibits ATPase activity, inducing proinflammatory mechanistic changes in tumor-infiltrating leukocytes. Syngeneic tumor studies using human CD39 knock-in mice show that SRF617 can modulate CD39 levels on immune cells in vivo and can penetrate the TME of an orthotopic tumor, leading to increased CD8+ T-cell infiltration. Targeting CD39 is an attractive approach for treating cancer, and, as such, the properties of SRF617 make it an excellent drug development candidate.

Abstract
Abstract
DHX9 is a multifunctional DEAH-box ATP-independent RNA helicase which has been reported to play important roles in replication, transcription, translation, RNA splicing and RNA processing which contribute to DHX9’s role in maintenance of genomic stability. Functionally, DHX9’s role involves binding to as well as unwinding and/or resolving double-stranded and single-stranded DNA/RNA, DNA/RNA hybrids (R-loops), circular RNA and DNA/RNA G quadraplexes. Overexpression of DHX9 is evident in multiple cancer types, including colorectal cancer (CRC) and lung cancer. In addition, microsatellite instable (MSI) tumors exhibiting defective mismatch repair (dMMR) show a strong dependence on DHX9, making this helicase an attractive target for oncology drug discovery.
Here we describe data supporting targeting DHX9 in MSI CRC as a novel therapeutic, and the first identification of potent and selective in vitro and in vivo small molecule inhibitors of DHX9. We demonstrate that DHX9 inhibition in MSI CRC, delivered either through siRNA knockdown or compound treatment, leads to an increase in RNA/DNA secondary structures such as R-loops and circRNA (i.e. circBRIP1) inducing replication stress. Cell lines that are dMMR (i.e. MSI) are unable to resolve this replication stress, resulting in prevention of DNA replication in S phase and later onset of apoptosis. We were able to confirm this selective dependency in a panel of 20 CRC cell lines; anti-proliferative effects mediated by DHX9 inhibition were dependent on cell line dMMR status in a 10-day proliferation assay. Furthermore, compound 1, an orally bioavailable DHX9 inhibitor was used to investigate in vivo efficacy in MSI CRC (LS411N) and MSS CRC (SW480) xenograft models. Compound 1 was well tolerated across the 28-day treatment period with robust and durable tumor regression (TGI = 105 %) observed in the LS411N tumor xenograft model only. In addition, following cessation of treatment, minimal tumor regrowth was observed in a 28-day post treatment window. Tumor and plasma concentrations of compound 1 and changes in pharmacodynamic markers of DHX9 inhibition, such as circBRIP1 mRNA, were measured and resulting PK and PD data were highly correlated. Together, these preclinical data validate DHX9 as a tractable new target with potential utility as a novel treatment for patients with MSI CRC.

Abstract
ObjectiveThe study aimed to examine the association between patient-reported oral health outcomes and the dental service sector and trust in dentists. The possible interaction effect of trust on this association was also explored.MethodsRandomly selected adults aged over 18 years living in South Australia were surveyed using self-administered questionnaires. The outcome variables were self-rated dental health and the evaluation outcome of the Oral Health Impact Profile. The dental service sector and the Dentist Trust Scale were included in bivariate and adjusted analyses with sociodemographic covariates.ResultsData from 4,027 respondents were analyzed. Unadjusted analysis showed that poor dental health and oral health impact were associated with sociodemographic characteristics, including lower income/education, public dental service, and lower trust in dentists (p < 0.01). Adjusted associations were similarly maintained (p < 0.05) but attenuated with the loss of statistical significance, mainly in the trust tertiles. Lower trust in dentists in the private sector had an interaction effect, with a higher prevalence ratio of oral health impact (prevalence ratio = 1.51; 95% confidence interval, 1.06–2.14; p < 0.05).ConclusionPatient-reported oral health outcomes were associated with sociodemographic characteristics, the dental service sector, and trust in dentists.Implications for public healthThe inequality of oral health outcomes between dental service sectors needs to be addressed both independently and in association with covariates including socioeconomic disadvantage.

Abstract
BACKGROUND Teeth affected with enamel defects (EDs) are at an increased risk of dental caries. In spite of improving oral health status overall in Australia, Indigenous Australians still experience higher rates of dental caries than non-Indigenous Australians. This study reports on the prevalence of EDs and dental caries experience among Indigenous children in the Kimberley region of Western Australia. METHODS Health status of all the primary teeth (ICDAS II criteria) and the presence of EDs on index teeth (modified Dental Defects of Enamel index; DDE) of young Indigenous children who participated in a 2-arm intervention trial was recorded. Generalized estimating equations were used to estimate the association between EDs and dental caries and effect estimates were presented as odds ratios and associated 95% confidence intervals. RESULTS Person-level prevalence, from 237 children (mean age 3.6 years, standard deviation 1.7) assessed for EDs, was 58% and tooth-level prevalence was 24%. Teeth affected with demarcated or diffuse defects were associated with a twofold higher odds of having caries experience, odds ratio (OR) 2.5, 95% confidence interval (CI) 1.7-3.7 and OR 2.7, 95% CI 1.7-4.0 respectively. CONCLUSIONS The presence of EDs among young Indigenous children was associated with a higher odds of caries experience among affected teeth.

Predictive factors for pre-intervention rebleeding in aneurysmal subarachnoid haemorrhage: a systematic review and meta-analysis. Neurosurg Rev 2022; 46:24.

Abstract
Rebleeding before intervention is a devastating complication of aneurysmal subarachnoid haemorrhage (aSAH). It often occurs early and is associated with poor outcomes. We present a systematic review and meta-analysis to identify potential predictors of rebleeding in aSAH. A database search identified studies detailing the occurrence of pre-intervention rebleeding in aSAH, and 809 studies were screened. The association between rebleeding and a variety of demographic, clinical, and radiological factors was examined using random effects meta-analyses. Fifty-six studies totalling 33,268 patients were included. Rebleeding occurred in 3,223/33,268 patients (11.1%, 95%CI 9.4-13), with risk decreasing by approximately 0.2% per year since 1981. Systolic blood pressure (SBP) during admission was higher in patients who rebled compared with those who did not (MD 7.4 mmHg, 95%CI 2.2 - 12.7), with increased risk in cohorts with SBP > 160 mmHg (RR 2.12, 95%CI 1.35-3.34), but not SBP > 140 mmHg. WFNS Grades IV-V (RR 2.05, 95%CI 1.13-3.74) and Hunt-Hess grades III-V (RR 2.12, 95%CI 1.38-3.28) were strongly associated with rebleeding. Fisher grades IV (RR 2.24, 95%CI 1.45-3.49) and III-IV (RR 2.05, 95%CI 1.17-3.6) were also associated with an increased risk. Awareness of potential risk factors for rebleeding is important when assessing patients with aSAH to ensure timely management in high-risk cases. Increased SBP during admission, especially > 160 mmHg, poorer clinical grades, and higher radiological grades are associated with an increased risk. These results may also aid in designing future studies assessing interventions aimed at reducing the risk of rebleeding.

Abstract
The association of low income with poor health is widely recognized, but why some low-income individuals do not experience poor health remains unclear. The aim of this study was to determine whether greater positive personality trait scores modify the association between income and oral and general health-related quality of life (OHRQoL and HRQoL) among a representative sample of the South Australian population. Cross-sectional self-rated questionnaire data from a sample of 3645 adults in 2015-2016 were used for secondary analysis. In four factorial ANOVA models, the main effects, interaction, and effect modification of personality traits [measured using the Ten-Item Personality Inventory (TIPI)] on the association between income and OHRQoL [measured using the Oral Health Impact Profile (OHIP-14)] and HRQoL [measured using the European Quality of Life indicator (EQ-5D-3L)] were assessed. In the low-income group, participants with greater TIPI scale scores had lower means for the OHIP-14 and the EQ-5D-3L (better OHRQoL and HRQoL). Greater emotional stability scores modified the association between low income and HRQoL and OHRQoL. Stronger positive personality traits, such as emotional stability, appear to ameliorate the adverse effect of income inequalities in health.

Access to dental care barriers and poor clinical oral health in Australian regional populations. Aust Dent J 2022; 67:344-351. [PMID: 35765724 PMCID: PMC10084231 DOI: 10.1111/adj.12930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/08/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND This paper investigated the associations between oral health with behavioural, demographic, periodontitis risk, financial and access to dental care barriers and compared the results in three Australian regional areas. METHODS Data were obtained from the Australian National Study of Adult Oral Health (2017-18). Oral health status was measured using DMFT-score, and mean numbers of decayed, missing or filled teeth and periodontitis prevalence using the Center for Disease Control and Prevention (CDC) and the American Academy of Periodontology (AAP) Periodontal Classification. Analysis included these dependent variables by three regional areas, seven socio-demographic variables, two periodontal disease risk-factors, two preventive dental behaviours, two barriers to dental care and three access to dental care variables. RESULTS Of the 15,731 people interviewed, 5,022 were examined. There was no significant difference in periodontitis prevalence between the regions. All the socio-demographic characteristics, periodontal disease risk-factors, preventive dental behaviours were significantly associated with at least one of the dental caries indicators. In multivariable analysis, there was no significant association between regional location with any of the four clinical dental caries variables. CONCLUSION Poorer oral health outside major cities was associated with household income, education level, higher smoking, usual reason for and frequency of dental visiting. © 2022 Australian Dental Association.

Abstract
OBJECTIVE Although HRQoL tools such as the EQ-5D-3L are significant in determining health status, these measures have not been validated in general populations in Australia. This study aims to psychometrically validate the EQ-5D-3L in a large population sample in Australia for the first time. METHODS The EQ-5D-3L was included in the Dental Care and Oral Health study (DCOHS), conducted in a South Australian population sample. The participants were 23-91 years old, and 44.1% were male. The EQ-5D-3L was responded to on a three-point rating scale ("none"/"no", "some" and "extremely"/"unable"/"confined"). We employed the area under the receiver operating characteristic curve (AUROC) to evaluate whether the EQ-5D-3L total score could identify participants with diagnosed diseases and mental health disorders. Psychometric validation of the EQ-5D-3L investigated dimensionality with Exploratory Graph Analysis, model fit, floor/ceiling effects and criterion validity. RESULTS The EQ-5D-3L comprised two dimensions, Activities and Symptoms. According to Root Mean Squared Error of Approximation (RMSEA) (<.05) and Comparative Fit Index (CFI) (>.950), the 2-dimensional structure showed excellent model fit with good reliability for the Activities subscale (Ωc = 0.80-95% CI [0.77, 0.83]), and poor reliability for the Symptom subscale (Ωc = 0.56-95% CI [0.53, 0.58]). The EQ-5D-3L showed adequate reliability (Ωc = 0.70-95% CI [0.67, 0.72]). The EQ-5D-3L showed good discrimination for diagnosed diseases (ranging from 64.3% to 86.3%). Floor/ceiling effects were observed across all items. The EQ-5D-3L total score discriminated between respondents who were experiencing health conditions (e.g. cancer, cardiovascular disease, stroke) from healthy individuals. DISCUSSION Despite the ceiling effects, the EQ-5D-3L displayed good psychometric properties as an HRQoL measure and discriminated between health states in the general South Australian population. Further research should investigate the psychometric properties of the EQ-5D-5L in South Australia and whether an increased number of response categories can mitigate the observed ceiling effects.

The triangle of inequality in dental services: arguments for a new conceptual framework. Arch Public Health 2022; 80:60. [PMID: 35180890 PMCID: PMC8855648 DOI: 10.1186/s13690-022-00826-1] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2021] [Accepted: 02/08/2022] [Indexed: 11/10/2022] Open
Abstract
This short communication paper aimed to compile the main determinants of inequality in dental services by distinguishing between access, utilisation, and provision of dental services. Recent findings integrated, and a dedicated conceptual framework entitled “Triangle of inequality in dental services” has been suggested. These can contribute a rich knowledge in this area and open a new window for policymakers and researchers to seek applied interventions to decrease inequality and improve access and utilisation in communities. This paper aims to synthesise the available evidence and add value to the scope. It highlights a dedicated concept for inequality in dental services beyond other areas of public health.

Abstract
Abstract
Background
Improving access to health services is a way towards achieving Universal Health Coverage (UHC) in oral health. The purpose of this review was to map the determinants of access to dental services within a UHC framework.
Methods
Scoping review methods were adopted for the review. PUBMED, Scopus, ISI Web of Science and ProQuest were searched for academic literature on determinants of access to dental services in OCED countries. Articles published in the last 10 years were included. No restriction was placed on study methods; only articles in the English language were included. Qualitative synthesis was conducted, also including trend analysis and mapping exercise
Results
A total of 4320 articles were identified in the initial search; 60 articles were included in the qualitative synthesis. The results indicate 7 main themes as the determinants of access to dental services: family level, culture, health status, affordability of services, Social environment, geographic and transportation. Defined determinants of access to dental services, family-level factors, culture and geographical access to dental services, can fill the population axis of the UHC cube. Social environment determinants and affordability of services fill the gap of financial protection as another axis of the UHC cube and finally, availability of dental services and the individual's health status are aligned with the appropriateness of services, the third axis of the UHC cube.
Conclusions
This scoping review has identified family-level and cultural, health status, affordability, and availability of services, social environment, and geographic factors contributing towards the inequality in access towards dental services. In addition to considering these main determinants, it is important for policymakers to pay more attention to social and cultural access determinants.
Key messages
An exact definition of access to services should be defined and implemented in the dental literature. Health Policymakers besides considering the derived themes of access into dental services should pay attention to social and cultural access determinants.

Inequalities in Utilisation and Provision of Dental Services: A Scoping Review. Eur J Public Health 2021. [DOI: 10.1093/eurpub/ckab165.274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/14/2022] Open
Abstract
Abstract
Background
To explore the main determinants of inequality in both provision and utilisation of dental services in OECD countries.
Methods
Four databases were searched up to 8 Aug 2020 applying the relevant keywords. Thematic analysis was used for synthesizing and extracting data. Trend analysis was applied to determine the trends of the inequality determinants.
Results
Thematic analysis led to 53 sub-sub-themes, 13 sub-themes and 6 main-themes. The main themes represent the main inequality determinants for both utilisation and provision of dental services. The streamgraph illustrates that fewer studies have been conducted on social and cultural determinants, and in almost all determinants the trend of published articles has been increasing since 2007 except for health policies.
Conclusions
Inequality in the utilisation and provision of dental services is addressed by various factors including individual, social, cultural and economic determinants, health policies and availability of services. The first four determinants are related to utilisation and the last two are related to the provision of services. All these aspects must be considered to reduce inequality in dental services.
Key messages
Service Utilisation, Provision and access to service int the dental literature should be distiguished and redefined. Researchers and policymakers should pay attention simultaneously to all structured determinants of inequality in the dental services.

Tele-rehabilitation of upper-extremity hemiparesis after stroke: Proof-of-concept randomized controlled trial of in-home Constraint-Induced Movement therapy. Restor Neurol Neurosci 2021; 39:303-318.

Abstract
BACKGROUND Although Constraint-Induced Movement therapy (CIMT) has been deemed efficacious for adults with persistent, mild-to-moderate, post-stroke upper-extremity hemiparesis, CIMT is not available on a widespread clinical basis. Impediments include its cost and travel to multiple therapy appointments. To overcome these barriers, we developed an automated, tele-health form of CIMT. OBJECTIVE Determine whether in-home, tele-health CIMT has outcomes as good as in-clinic, face-to-face CIMT in adults ≥1-year post-stroke with mild-to-moderate upper-extremity hemiparesis. METHODS Twenty-four stroke patients with chronic upper-arm extremity hemiparesis were randomly assigned to tele-health CIMT (Tele-AutoCITE) or in-lab CIMT. All received 35 hours of treatment. In the tele-health group, an automated, upper-extremity workstation with built-in sensors and video cameras was set-up in participants' homes. Internet-based audio-visual and data links permitted supervision of treatment by a trainer in the lab. RESULTS Ten patients in each group completed treatment. All twenty, on average, showed very large improvements immediately afterwards in everyday use of the more-affected arm (mean change on Motor Activity Log Arm Use scale = 2.5 points, p < 0.001, d' = 3.1). After one-year, a large improvement from baseline was still present (mean change = 1.8, p < 0.001, d' = 2). Post-treatment outcomes in the tele-health group were not inferior to those in the in-lab group. Neither were participants' perceptions of satisfaction with and difficulty of the interventions. Although everyday arm use was similar in the two groups after one-year (mean difference = -0.1, 95% CI = -1.3-1.0), reductions in the precision of the estimates of this parameter due to drop-out over follow-up did not permit ruling out that the tele-health group had an inferior long-term outcome. CONCLUSIONS This proof-of-concept study suggests that Tele-AutoCITE produces immediate benefits that are equivalent to those after in-lab CIMT in stroke survivors with chronic upper-arm extremity hemiparesis. Cost savings possible with this tele-health approach remain to be evaluated.

The results indicate 7 main themes as the determinants of access to dental services: family condition, cultural factors, health demands, affordability of services, availability of services, socio-environmental factors, geographical distance. Defined determinants of access to dental services, family condition, cultural factors and geographical access to dental services can fill the population axis of the UHC cube. Health demands and affordability of services fill the gap of financial protection as another axis of the UHC cube and finally, availability of dental services and socio-environmental factors are aligned with the appropriateness of services, the third axis of the UHC cube. CONCLUSION According to the results, family condition and cultural, health demands, affordability and availability of services, social environment, and geographic factors can affect dental health access and equality. Socio-cultural determinations also need to be considered in applied planning. Addressing these factors to improve access to dental services can pave the way for achieving universal health coverage in oral health and should be considered in different levels of policymaking.

Is Bigger Better? Living Donor Kidney Volume as Measured by the Donor CT Angiogram in Predicting Donor and Recipient eGFR after Living Donor Kidney Transplantation. J Transplant 2021; 2021:8885354. [PMID: 34336253 PMCID: PMC8286185 DOI: 10.1155/2021/8885354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2020] [Accepted: 06/30/2021] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND The role of kidney volume measurement in predicting the donor and recipient kidney function is not clear. METHODS We measured kidney volume bilaterally in living kidney donors using CT angiography and assessed the association with the donor remaining kidney and recipient kidney (donated kidney) function at 1 year after kidney transplantation. Donor volume was categorized into tertiles based on lowest, middle, and highest volume. RESULTS There were 166 living donor and recipient pairs. The mean donor age was 44.8 years (SD ± 10.8), and donor mean BMI was 25.5 (SD ± 2.9). The recipients of living donor kidneys were 64% male and had a mean age of 43.5 years (SD ± 13.3). Six percent of patients experienced an episode of cellular rejection and were maintained on dialysis for a mean of 18 months (13-32) prior to transplant. Kidney volume was divided into tertiles based on lowest, middle, and highest volume. Kidney volume median (range) in tertiles 1, 2, and 3 was 124 (89-135 ml), 155 (136-164 ml), and 184 (165-240 ml) with donor eGFR ml/min (adjusted for body surface area expressed as ml/min/1.73 m2) at the time of donation in each tertile, 109 (93-129), 110 (92-132), and 101 ml/min (84-117). The median (IQR) eGFR in tertiles 1 to 3 in kidney recipients at 1 year after donation was 54 (44-67), 62 (50-75), and 63 ml/min (58-79), respectively. The median (IQR) eGFR in tertiles 1 to 3 in the remaining kidney of donors at 1 year after donation was 59 (53-66), 65 (57-72), and 65 ml/min (56-73), respectively. CONCLUSION Bigger kidney volume was associated with better eGFR at 1 year after transplant in the recipient and marginally in the donor remaining kidney.

Oral health changes among Indigenous and non-Indigenous Australians: findings from two national oral health surveys. Aust Dent J 2021; 66 Suppl 1:S48-S55. [PMID: 33899961 DOI: 10.1111/adj.12849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Revised: 04/16/2021] [Accepted: 04/18/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Historically, Indigenous Australians experienced poorer oral health than non-Indigenous Australians. We aimed to ascertain if Indigenous Australian oral health improved relative to non-Indigenous oral health between the 2004-06 and 2017-18 National Surveys of Adult Oral Health (NSAOH). METHODS Both NSAOHs were population-based cross-sectional surveys of Australian adults aged 15 years or more. In both surveys, representative samples of adults were drawn through a three-stage, stratified sample design within metropolitan and regional areas in each state/territory. Frequencies of Indigenous and non-Indigenous self-reported and clinical oral health variables were ascertained, and differences were calculated between the 2004-06 and 2017-18 NSAOHs. Ninety-five per cent confidence intervals were calculated and weights were used to account for the complex sampling methodology of both surveys. RESULTS In 2004-06, 229 Indigenous and 13 882 non-Indigenous Australians provided self-report data, and 87 and 5418 of these had dental examinations, respectively. In 2017-18, 334 Indigenous and 15 392 non-Indigenous Australians provided self-report data, and 84 and 4937 of them had dental examinations respectively. Between the surveys, relative to their non-Indigenous counterparts, Indigenous Australians experienced greater levels of: inadequate dentition (4.2%), experience of toothache (4.8%), problem-based dental attendance (4.5%) and 1+ teeth decayed, missing or filled (4.4%). CONCLUSIONS The gap between poor self-reported and clinical oral health between Indigenous and non-Indigenous Australians was greater in the more recent survey.

Abstract
BACKGROUND As the proportion and number of older people in Australia continue to grow, innovative means to tackle primary care and prevention are necessary to combat the individual, social and economic challenges of non-communicable diseases. OBJECTIVE To assess risk factors (or predictors) for oral and general health outcomes and quality of life of older people (75+ years.) attending general practice (GP) clinics in South Australia. METHODS Data were collected from older people attending 48 GP clinics in metropolitan South Australia. Age, sex, education, living arrangement, material standards, chronic conditions and nutrition were assessed as risk factors. Global self-rated oral and general health and quality of life (OHIP Severity and EQ-5D Utility) were included as outcome measures. RESULTS A total of 459 participants completed the study; response rate was 78%. In the adjusted models, high satisfaction with material standards and good nutritional health were positively associated with all four oral and general health measures. Sex (β = -0.08), age (β = -0.09) and number of chronic conditions (β = -0.12) were negatively associated with EQ-5D, while living arrangement (β = 0.07) was positively associated. Further, having four or more chronic conditions (RR:1.47) was significantly associated with self-rated general health. CONCLUSION Satisfaction with material standards and nutritional risk were consistent predictors for oral and general health outcomes and quality of life of older people visiting GP clinics.

Abstract
INTRODUCTION The management of early childhood caries (ECC) is challenging. OBJECTIVES A model of care based on Atraumatic Restorative Treatment and the Hall Technique (ART-HT) to manage ECC was evaluated among remote Aboriginal communities in Australia. METHODS Aboriginal communities in the North-West of Western Australia were invited to participate and consenting communities were randomized into early or delayed intervention for the management of ECC. Children were examined at baseline and at the 11-mo follow-up. The early intervention group (test) was provided with the ART-based dental care at baseline while the delayed intervention group (control) was advised to seek care through the usual care options available within the community. At follow-up, both groups were examined by calibrated examiners, and were offered care using the ART-HT approach. Changes from baseline to follow-up in caries experience were tested using paired tests. Multivariate analysis after multiple imputation of missing data used generalised estimating equation (GEE) controlling for clustering within communities. RESULTS A total of 25 communities and 338 children (mean age = 3.6 y, SD 1.7) participated in the study (test = 177). At follow-up, 231 children were examined (68% retention, test = 125). At follow-up, children in the test group had more filled teeth (test filled teeth = 1.2, control filled teeth = 0.2, P < 0.001) and decreased levels of decayed teeth (mean test = 0.7 fewer teeth with decay, mean control = 1.0 more tooth with decay, P < 0.001). GEE analysis controlled for baseline caries experience, age, sex, and community water fluoride levels found increased rates of untreated decayed teeth (RR = 1.4, P = 0.02) and decreased rates of filled teeth (RR = 0.2, P < 0.001) at follow-up among the control group. CONCLUSION A model of care relying on the principles of minimally invasive atraumatic approaches enabled the delivery of effective dental services to young children (<6 y) in remote Aboriginal Australian communities resulting in increased levels of care and improved oral health. KNOWLEDGE TRANSFER STATEMENT This cluster-randomized trial tested a multi-component model of dental care to young children with ECC in remote Aboriginal communities in Australia. The intervention, based on the atraumatic approaches using minimally invasive techniques encompassing preventive care, Atraumatic Restorative Treatment and the Hall Technique (ART-HT), delivered more restorative care and reduced the incidence of caries. This model of care was more effective than available standard care and should be incorporated into mainstream service delivery programs.

Abstract
Introduction: COVID-19 requires methods for screening patients that adhere to physical
distancing and other Centers for Disease Control and Prevention guidelines.
There is little data on the use of on-demand telehealth to meet this
need. Methods: The functional performance of on-demand telehealth as a COVID-19 remote
patient screening approach was conducted by analysing 9270 patient
requests. Results: Most on-demand telehealth requests (5712 of 9270 total requests; 61.6%) had a
visit reason that was likely COVID-19 related. Of these, 79.1% (4518 of
5712) resulted in a completed encounter and 20.9% (1194 of 5712) resulted in
left without being seen. Of the 4518 completed encounters, 19.1% were
referred to an urgent care centre, emergency department or COVID-19 testing
centre. The average completed encounter wait time was 26.5 min and the mean
visit length was 8.8 min. For patients that completed an encounter 42.8%
(1935 of 4518) stated they would have sought in-person care and 9.1% stated
they would have done nothing if on-demand telehealth was unavailable. Discussion: On-demand telehealth can serve as a low-barrier approach to screen patients
for COVID-19. This approach can prevent patients from visiting healthcare
facilities, which reduces physical contact and reduces healthcare worker use
of personal protective equipment.

Abstract
BACKGROUND As the strategies proposed for oral health improvement in developed countries are not adapted for developing ones, this study aimed to identify the challenges of oral health policy implementation in Iran as a low-income developing country. METHODS This qualitative study was conducted in 2019 in Iran as a middle-eastern developing country. The study population consisted of experts who had experience in oral health and were willing to participate in the study. Snowball sampling was used to select 12 participants for semi-structured interviews and saturation was achieved after 16 interviews. Guba and Lincoln criteria including credibility, transferability, confirmability and dependability were used to determine reliability and transparency, and finally a five-step framework analysis method was used to analyze the data. RESULTS The analysis of the interviews resulted in identification of 7 main themes that were categorized into 5 problems of policy implementation as proposed by the Matus framework. The main themes of executive and preventive challenges to implement oral health policies were categorized as organizational problems, the main themes of educational and resource challenges were situated as material problems, and the main themes of insurance, policy making and trusteeship challenges were considered as legal, policymaking and perspective. CONCLUSION The implementation of oral health policies has faced some challenges. It seems that the national coverage of oral health and integration of these services in prevention and serious attention to the private sector can be considered as the most important strategies for achieving improved oral health in Iran.

Abstract
OBJECTIVES Dentist-patient relationships (DPRs) are a key component in clinical encounters with potential benefits for oral health outcomes. This study aimed to investigate whether better DPR variables are associated with higher oral health-related quality of life (OHRQoL). METHODS A total of 12 245 adults aged 18 years or over were randomly sampled from South Australia in 2015-2016. Data were collected from self-complete questionnaires and analysed as a cross-sectional design. The outcome variable was the Oral Health Impact Profile (OHIP-14). Explanatory DPR variables included trust in dentists, satisfaction with dental care, and dental fear. Covariates comprising oral health behaviours, dental services, demographics, and socioeconomic status were included as potential confounding variables. Bivariate correlation analyses and multivariable linear regression were performed for the associations among explanatory, outcome variables and other covariates. RESULTS Response data were analysed from 4220 participants (response rate = 41.9%). Unadjusted mean total scores of DPR variables and OHIP-14 were associated with most of the study participants' characteristics (P < .05). Bivariate correlations among DPR variables and OHIP-14 showed a diverse range of coefficients (|r| or |ρ|=0.22-0.67). Multivariable regression analyses in both individual/clustered block entry and full model indicated that higher satisfaction and less dental fear (B = -0.039 and 0.316, respectively in the full model) were associated with lower OHIP-14 after adjusting for possible confounders (P < .01). CONCLUSIONS This study found that favourable DPR variables, mainly greater satisfaction and less dental fear are positively associated with better OHRQoL. Further studies are warranted to investigate the causality and mediation/moderation of DPR variables on oral health outcomes.

A characterization of ABL-101 as a potential tracer for clinical fluorine-19 MRI. NMR IN BIOMEDICINE 2020; 33:e4212. [PMID: 31724252 DOI: 10.1002/nbm.4212] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2019] [Revised: 10/10/2019] [Accepted: 10/18/2019] [Indexed: 06/10/2023]
Abstract
The two main challenges that prevent the translation of fluorine-19 (19 F) MRI for inflammation monitoring or cell tracking into clinical practice are (i) the relatively low signal-to-noise ratio generated by the injected perfluorocarbon (PFC), which necessitates long scan times, and (ii) the need for regulatory approval and a high biocompatibility of PFCs that are also suitable for MRI. ABL-101, an emulsion of perfluoro(t-butylcyclohexane), is a third-generation PFC that is already used in clinical trials, but has not yet been used for 19 F MRI. The objective of this study was therefore to assess the performance of ABL-101 as a 19 F MRI tracer. At magnetic field strengths of 3, 9.4 and 14.1 T, the CF3 groups of ABL-101 generated a large well-separated singlet with T2 /T1 ratios of >0.27, >0.14 and > 0.05, respectively. All relaxation times decreased with the increase in magnetic field strength. The detection limit of ABL-101 in a 0.25 mm3 voxel at 3 T, 37°C and with a 3-minute acquisition time was 7.21mM. After intravenous injection, the clearance half-lives of the ABL-101 19 F MR signal in mouse (n = 3) spleen and liver were 6.85 ± 0.45 and 3.20 ± 0.35 days, respectively. These results demonstrate that ABL-101 has 19 F MR characteristics that are similar to those of PFCs developed specifically for MRI, while it has clearance half-lives similar to PFCs that have previously been used in large doses in non-MRI clinical trials. Overall, ABL-101 is thus a very promising candidate tracer for future clinical trials that use 19 F MRI for cell tracking or the monitoring of inflammation.

Comparative Longitudinal Study on the Impact Root Canal Treatment and Other Dental Services Have on Oral Health-related Quality of Life Using Self-reported Health Measures (Oral Health Impact Profile-14 and Global Health Measures). J Endod 2019; 45:985-993.e1. [PMID: 31202516 DOI: 10.1016/j.joen.2019.05.002] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2018] [Revised: 03/20/2019] [Accepted: 05/01/2019] [Indexed: 11/19/2022]
Abstract
INTRODUCTION The literature assessing quality of life for subjects who have undergone root canal treatment (RCT) is scarce. The aim of this study was to compare the effect of RCT with other dental services (exodontia, restorative, prosthodontics, periodontics, and negative controls [preventative and scale and clean]) on oral health-related quality of life. METHODS A random sample of 3000 adults aged 30-61 years was obtained from the Australian electoral roll in 2009. Data were collected through questionnaires, dental service logbooks, and treatment receipts. The impact their dentition had at baseline and the 2-year follow-up for the Oral Health Impact Profile-14 and the self-rated dental health score followed by "global transition statement of change" (GTSC) was assessed. Binary regression models were used to compare the outcomes. RESULTS Responses were collected from 1096 respondents (response rate = 36.5%). After adjustment (for age, sex, household income, and reason for visit), the RCT group had significant differences (P ≤ .05) to other dental services at the 2-year follow-up using the Oral Health Impact Profile-14 (odds ratio = 0.34; 95% confidence interval, 0.12-0.96) and GTSC (odds ratio = 0.29; 95% confidence interval, 0.09-0.88) but not with individual treatment groups. Using the self-rated dental health score/GTSC, only the prosthodontic treatment group had a significant difference to the RCT group at baseline, whereas the negative controls (P ≤ .01) had significant differences to the RCT group with the odds for improved health 5 times higher, at 2-year follow-up. CONCLUSIONS The RCT group presented with similar oral health-related quality of life when compared with the other individual treatment groups; however, they consistently reported poorer oral health outcomes when the negative controls were included.

Doctor-Patient Communication in an Outpatient Setting. IRISH MEDICAL JOURNAL 2019; 112:934. [PMID: 31411016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/10/2023]
Abstract
Aim To evaluate doctor patient communication within gynaecological oncology services in Ireland. Methods An anonymous and confidential 20 question survey was designed by the patient advocacy group ISGOPPI and distributed in three gynaecological oncology outpatient clinics in tertiary referral centres. Results A total of 84 patients completed the survey in the 3 Dublin hospitals. Doctors surveyed ranged from senior house officer to consultant level. Overall women were very satisfied with the communication they had received from their doctor. 85% felt that they the doctor listened to them and took their opinion into account. 84% of patients felt that the doctor’s body language was appropriate throughout the consultation. One of the main issues for women surveyed was waiting times. 33% of women waited over an hour to see their doctor and over 30% of women did not receive contact details of the clinical nurse specialist. Conclusion Overall our study shows that patients in gynae-oncology clinics are satisfied with the communication from their doctors. The main issues for patients were waiting times and contact details for follow up questions.

The exercise of human rights and citizenship by older adults with an intellectual disability in Ireland. JOURNAL OF INTELLECTUAL DISABILITY RESEARCH : JIDR 2018; 62:875-887. [PMID: 30125431 DOI: 10.1111/jir.12543] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/24/2017] [Revised: 04/30/2018] [Accepted: 07/19/2018] [Indexed: 06/08/2023]
Abstract
BACKGROUND The UN Convention on the Rights of Persons with Disabilities (CRPD) provides the benchmark for assessing human rights and citizenship for people with disabilities. This emphasises autonomy, choice, independence, equality and participation for individuals as its fundamental guiding principles. METHODS This paper explores the exercise of human rights and citizenship for older adults with intellectual disabilities (ID) in Ireland, including choice-making, advocacy and political participation. Cross-sectional data (n = 701) is drawn from wave 2 of the Intellectual Disability Supplement to The Irish Longitudinal Study on Ageing. Rates of participation are reported, along with bivariate associations across a range of demographic, personal and social variables, while factors associated with level of choice-making and voting are explored. RESULTS We found very low rates of choice-making, advocacy and political participation amongst this population. Two factors of choice were explored: key life choice and everyday choice. Some commonalities were identified between the two factors, yet key differences were also noted. Type of residence was the strongest predictor of key life choice yet not significant in everyday choice, while the reverse was true for functioning in activities of daily living. Other factors were also significant in determining choice, including level of ID, contact with family, functional limitation, literacy, age, having friends and respondent type. CONCLUSIONS Low rates of participation reported here impinge on the rights of older adults with ID under the principles of the UN CRPD. Choice-making emerged as a multi-factorial phenomenon, with different factors important depending on the type of choice involved. This encourages a nuanced and personalised response from policy and support services to overcome individual challenges to participation as equal citizens. The significance of respondent type also highlights the difficulty of including self-report, supported and proxy participants in ID research.

Cardiomyogenic differentiation of human bone marrow-derived mesenchymal stem cell spheroids within electrospun collagen nanofiber mats. J Biomed Mater Res A 2018; 106:3303-3312.

Abstract
Collagen is the major structural protein in myocardium and contributes to tissue strength and integrity, cellular orientation, and cell-cell and cell-matrix interactions. Significant post-myocardial infarction related loss of cardiomyocytes and cardiac tissue, and their subsequent replacement with fibrous scar tissue, negatively impacts endogenous tissue repair and regeneration capabilities. To overcome such limitations, tissue engineers are working toward developing a 3D cardiac patch which not only mimics the structural, functional, and biological hierarchy of the native cardiac tissue, but also could deliver autologous stem cells and encourage their homing and differentiation. In this study, we examined the utility of electrospun, randomly-oriented, type-I collagen nanofiber (dia = 789 ± 162 nm) mats on the cardiomyogenic differentiation of human bone marrow-derived mesenchymal stem cells (BM-MSC) spheroids, in the presence or absence of 10 μM 5-azacytidine (aza). Results showed that these scaffolds are biocompatible and enable time-dependent evolution of early (GATA binding protein 4: GATA4), late (cardiac troponin I: cTnI), and mature (myosin heavy chain: MHC) cardiomyogenic markers, with a simultaneous reduction in CD90 (stemness) expression, independent of aza-treatment. Aza-exposure improved connexin-4 expression and sustained sarcomeric α-actin expression, but provided only transient improvement in cardiac troponin T (cTnT) expression. Cell orientation and alignment significantly improved in these nanofiber scaffolds over time and with aza-exposure. Although further quantitative in vitro and in vivo studies are needed to establish the clinical applicability of such stem-cell laden collagen nanofiber mats as cardiac patches for cardiac tissue regeneration, our results underscore the benefits of 3D milieu provided by electrospun collagen nanofiber mats, aza, and spheroids on the survival, cardiac differentiation and maturation of human BM-MSCs. © 2018 Wiley Periodicals, Inc.

Minimally Invasive Dentistry Based on Atraumatic Restorative Treatment to Manage Early Childhood Caries in Rural and Remote Aboriginal Communities: Protocol for a Randomized Controlled Trial. JMIR Res Protoc 2018; 7:e10322. [PMID: 30045834 PMCID: PMC6083045 DOI: 10.2196/10322] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2018] [Revised: 05/17/2018] [Accepted: 05/29/2018] [Indexed: 12/03/2022] Open
Abstract
Background The caries experience of Aboriginal children in Western Australia (WA) and elsewhere in Australia is more than twice that of non-Aboriginal children. Early childhood caries (caries among children <6 years) has a significant impact on the quality of life of children and their caregivers, and its management is demanding and commonly undertaken under general anesthesia. A randomized controlled trial using a minimally invasive dentistry approach based on Atraumatic Restorative Treatment (ART) in metropolitan Perth, WA, has demonstrated a significant reduction in the rate of referral to a dental specialist for dental care among children with early childhood caries, potentially reducing the need for treatment under general anesthesia. The tested approach was clinically successful and was without adverse effects on child dental anxiety. The model of ART-based primary care requires further testing and development if similar outcomes for Aboriginal children in remote and rural settings are to be achieved. Objective The study aims to develop, implement, and evaluate a remote primary care model to deliver effective primary dental services, encompassing treatment and preventive services, to Aboriginal preschool children (based on minimally invasive approaches including ART). Methods This is a two-arm parallel cluster randomized controlled study in which a test group will be provided with the intervention treatment at the start of the study and a control group will be provided with the intervention treatment 12 months after study commencement (delayed intervention). Participating communities, stratified by size of community (ie, number of children in the sample frame) and baseline caries experience, will be randomly assigned using a computer-generated block randomized list into immediate (test group) or delayed intervention (control group; provided with standard care). Informed consent will be obtained from all participants. Aboriginal research assistants will explain the study to the parents and assist the parents in completing the questionnaires. Participants in the randomized study will be examined at baseline and at 12 months follow-up by a calibrated examiner. Test group participants will subsequently be contacted and appropriate appointments coordinated for treatment. Control group participants will be provided with standard preventive care by the Aboriginal Health Workers and managed for treatment as per standard procedures. Results Community consultations have been undertaken and 26 communities have agreed to participate. Fieldwork is in progress to recruit study participants. Conclusions The significance of the study lies in its holistic approach to testing the model of care. Clinical evaluations as well as oral health‒related quality of life evaluations will be undertaken. Cost-effectiveness and cost-utility evaluations will assist in the development of policy options for oral health services for rural and remote communities. The elicitation of caregiver perspectives through focus group interviews will supplement the clinical, psychosocial, and cost-utility evaluations and provide a richer evaluation of the intervention.

Abstract
OBJECTIVE To explore and document self-reported factors contributing to Indigenous Australians' attendance and non-attendance at South Australian public dental clinics. METHODS Semi-structured interviews were conducted with people (18 males and 26 females) referred for oral care through the Aboriginal Liaison Program of the South Australian Dental Service. Thematic analysis was performed on 44 transcribed conversations and a conceptual model developed. RESULTS Persons completing all recommended treatment reported high self-efficacy, health literacy, social cohesion and previous use of dental services and presence of a health advocate. Those completing some recommended treatment reported achieving desired oral health outcome of relief of pain or system-level barriers to completion. Those reporting accessing no dental treatment in contrast reported varied and complex barriers to dental care. CONCLUSION AND IMPLICATIONS Differences in both individual and health service-related factors were evident. Individual-level factors related to health literacy, self-efficacy, and social control. Service factors related to availability of an advocate, service delivery, and culture. Practical service-level changes may alleviate the effects of individual-level factors.

Perfluorocarbon Enhanced Glasgow Oxygen Level Dependent (GOLD) Magnetic Resonance Metabolic Imaging Identifies the Penumbra Following Acute Ischemic Stroke. Am J Cancer Res 2018; 8:1706-1722.

Abstract
The ability to identify metabolically active and potentially salvageable ischaemic penumbra is crucial for improving treatment decisions in acute stroke patients. Our solution involves two complementary novel MRI techniques (Glasgow Oxygen Level Dependant (GOLD) Metabolic Imaging), which when combined with a perfluorocarbon (PFC) based oxygen carrier and hyperoxia can identify penumbra due to dynamic changes related to continued metabolism within this tissue compartment. Our aims were (i) to investigate whether PFC offers similar enhancement of the second technique (Lactate Change) as previously demonstrated for the T2*OC technique (ii) to demonstrate both GOLD metabolic imaging techniques working concurrently to identify penumbra, following administration of Oxycyte® (O-PFC) with hyperoxia. Methods: An established rat stroke model was utilised. Part-1: Following either saline or PFC, magnetic resonance spectroscopy was applied to investigate the effect of hyperoxia on lactate change in presumed penumbra. Part-2; rats received O-PFC prior to T2*OC (technique 1) and MR spectroscopic imaging, which was used to identify regions of tissue lactate change (technique 2) in response to hyperoxia. In order to validate the techniques, imaging was followed by [14C]2-deoxyglucose autoradiography to correlate tissue metabolic status to areas identified as penumbra. Results: Part-1: PFC+hyperoxia resulted in an enhanced reduction of lactate in the penumbra when compared to saline+hyperoxia. Part-2: Regions of brain tissue identified as potential penumbra by both GOLD metabolic imaging techniques utilising O-PFC, demonstrated maintained glucose metabolism as compared to adjacent core tissue. Conclusion: For the first time in vivo, enhancement of both GOLD metabolic imaging techniques has been demonstrated following intravenous O-PFC+hyperoxia to identify ischaemic penumbra. We have also presented preliminary evidence of the potential therapeutic benefit offered by O-PFC. These unique theranostic applications would enable treatment based on metabolic status of the brain tissue, independent of time from stroke onset, leading to increased uptake and safer use of currently available treatment options.

Abstract
Telehealth is a broad term used to describe the use of electronic or digital information and communications technologies to support clinical healthcare, patient and professional health related education, and public health and health administration. Telerehabilitation refers to the delivery of rehabilitation and habilitation services via information and communication technologies (ICT), also commonly referred to as” telehealth” technologies. Telerehabilitation services can include evaluation, assessment, monitoring, prevention, intervention, supervision, education, consultation, and coaching. Telerehabilitation services can be deployed across all patient populations and multiple healthcare settings including clinics, homes, schools, or community-based worksites. This document was adapted from the American Telemedicine Association’s (ATA) “A Blueprint for Telerehabilitation Guidelines” (2010) and reflects the current utilization of telerehabilitation services. It was developed collaboratively by members of the ATA Telerehabilitation Special Interest Group, with input and guidance from other practitioners in the field, strategic stakeholders, and ATA staff. Its purpose is to inform and assist practitioners in providing effective and secure services that are based on client needs, current empirical evidence, and available technologies. Rehabilitation professionals, in conjunction with professional associations and other organizations are encouraged to use this document as a resource for developing discipline-specific standards, guidelines, and practice requirements.

Abstract
The authors conducted a prospective trial to assess the feasibility of real time central molecular assessment of kidney transplant biopsy samples from 10 North American or European centers. Biopsy samples taken 1 day to 34 years posttransplantation were stabilized in RNAlater, sent via courier overnight at ambient temperature to the central laboratory, and processed (29 h workflow) using microarrays to assess T cell- and antibody-mediated rejection (TCMR and ABMR, respectively). Of 538 biopsy samples submitted, 519 (96%) were sufficient for microarray analysis (average length, 3 mm). Automated reports were generated without knowledge of histology and HLA antibody, with diagnoses assigned based on Molecular Microscope Diagnostic System (MMDx) classifier algorithms and signed out by one observer. Agreement between MMDx and histology (balanced accuracy) was 77% for TCMR, 77% for ABMR, and 76% for no rejection. A classification tree derived to provide automated sign-outs predicted the observer sign-outs with >90% accuracy. In 451 biopsy samples where feedback was obtained, clinicians indicated that MMDx more frequently agreed with clinical judgment (87%) than did histology (80%) (p = 0.0042). In 81% of feedback forms, clinicians reported that MMDx increased confidence in management compared with conventional assessment alone. The authors conclude that real time central molecular assessment is feasible and offers a useful new dimension in biopsy interpretation. ClinicalTrials.gov NCT#01299168.
