Hospital-wide healthcare-associated carbapenemase-producing Enterobacterales outbreak: risks of electric floor scrubbers in catering facilities and kitchens

BACKGROUND

Carbapenemase-producing Enterobacterales (CPE) are associated with poor clinical outcomes and can spread rapidly in healthcare settings. Environmental reservoirs are increasingly recognized as playing an important part in some nosocomial outbreaks.

AIM

To describe the investigation and control of a CPE outbreak, lasting several years, across two separate hospital sites within one organization.

METHODS

Investigation of multiple ward-level CPE cross-transmissions with a number of sporadic cases. Environmental sampling of ward environments, catering facilities and electric floor scrubbers was undertaken.

FINDINGS

Eleven patients over a 19-month period were identified as carrying healthcare-associated New Delhi metallo-beta-lactamase (NDM)-producing Enterobacter cloacae, and a further patient carried NDM Escherichia coli. E. cloacae isolates were indistinguishable on pulsed-field gel electrophoresis typing, supporting acquisition with a single point source. Environmental sampling found contamination of the electric floor scrubbers used for cleaning the hospital catering facilities and in the associated toilets. Standard outbreak response measures achieved control of ward outbreaks. Sporadic cases and hospital-wide cross-transmission were controlled after interventions on the central food-handling unit and by decommissioning affected floor scrubbers. Electric floor scrubbers were found to have the potential to disperse Gram-negative bacteria into the surrounding environment under experimental conditions.

CONCLUSION

This outbreak report demonstrates that catering facilities and kitchens can be involved in widespread healthcare outbreaks of enteric organisms. This is also the first report of the potential role of electric floor scrubbers in causing significant environmental contamination with CPE which may indicate a role in nosocomial transmission.

A conceptual framework for cautious escalation of anticancer treatment: How to optimize overall benefit and obviate the need for de-escalation trials

BACKGROUND

The developmental workflow of the currently performed phase 1, 2 and 3 cancer trial stages lacks essential information required for the determination of the optimal efficacy threshold of new anticancer regimens. Due to this there is a serious risk of overdosing and/or treating for an unnecessary long time, leading to excess toxicity and a higher financial burden for society. But often post-approval de-escalation trials for dose-optimization and treatment de-intensification are not performed due to failing resources and time. Therefore, the developmental workflow needs to be restructured toward cautious systemic cancer treatment escalation, in order to guarantee optimal efficacy and sustainability.

METHODS

In this manuscript we discuss opportunities to produce the information needed for cautious escalation, based on models of cancer growth and cancer kill kinetics as well as exploratory biomarkers, for the purpose of designing the optimal phase 3 superiority trial. Subsequently, we compare the sample size needed for a phase 3 superiority trial, followed by a necessary de-escalation trial with the sample size needed for a multi-arm phase 3 trial with intervention arms of differing intensity. All essential items are structured within a Framework for Cautious Escalation (FCE). The discussion uses illustrations from the breast cancer setting, but aims to be applicable for all cancers.

RESULTS

The FCE is a promising model of clinical development in oncology to prevent overtreatment and associated issues, especially with regard to the number of repetitive treatment cycles. It will hopefully increase the relevance and success rate of clinical trials, to deliver improved patient-centric outcomes.

Effectiveness of full Pulpotomy compared with Root canal treatment in managing teeth with signs and symptOms indicative of irreversible pulpitis: a protocol for prospectiVE meta-analysis of individual participant data of linked randomised clinical trials (PROVE)

BACKGROUND

Full pulpotomy has been proposed as an alternative to root canal treatment in teeth with signs and symptoms indicative of irreversible pulpitis (IRP), but the evidence is limited, relying on underpowered studies with a high risk of bias. The aim of this study is to conduct a prospective meta-analysis (PMA) of individual participant data of a series of individual randomised trials to provide robust evidence on the clinical and cost-effectiveness of pulpotomy compared with root canal treatment.

METHODS

Individual participant data will be obtained from a series of randomised trials designed and conducted by a consortium of multi-national investigators with an interest in vital pulp treatment. These individualised trials will be conducted using a specified protocol, defined outcomes, and outcome measures. Ten parallel-group randomised trials currently being conducted in 10 countries will provide data from more than 500 participants. The primary outcome is a composite measure defined as (1) the absence of pain indicative of IRP, (2) the absence of signs and symptoms indicative of acute or chronic apical periodontitis, and (3) the absence of radiographic evidence of failure including radiolucency or resorption. Individual participant data will be obtained, assessed, and checked for quality by two independent reviewers prior to the PMA. Pooled estimates on treatment effects will be generated using a 2-stage meta-analysis approach. The first stage involves a standard regression analysis in each trial to produce aggregate data on treatment effect estimates followed by an inverse variance weighted meta-analysis to combine these aggregate data and produce summary statistics and forest plots. Cost-effectiveness analysis based on the composite outcome will be undertaken as a process evaluation to evaluate treatment fidelity and acceptability by patients and dentists.

RESULTS

The research question and trial protocol were developed and approved by investigators in all 10 sites. All sites use shared resources including study protocols, data collection forms, participant information leaflets, and consent forms in order to improve flow, consistency, and reproducibility. Each site obtained its own Institutional Review Board approval, and trials were registered in appropriate open access platforms. Patient recruitment has started in most sites, as of July 2023.

DISCUSSION

PMA offers a rigorous, flexible, and efficient methodology to answer this important research question and provide results with improved generalisability and external validity compared with traditional trials and retrospective meta-analyses. The results of this study will have implications for both the delivery of clinical practice and structured clinical guidelines' development.

Reversal of MYB-dependent suppression of MAFB expression overrides leukaemia phenotype in MLL-rearranged AML

The transcription factor MYB plays a pivotal role in haematopoietic homoeostasis and its aberrant expression is involved in the genesis and maintenance of acute myeloid leukaemia (AML). We have previously demonstrated that not all AML subtypes display the same dependency on MYB expression and that such variability is dictated by the nature of the driver mutation. However, whether this difference in MYB dependency is a general trend in AML remains to be further elucidated. Here, we investigate the role of MYB in human leukaemia by performing siRNA-mediated knock-down in cell line models of AML with different driver lesions. We show that the characteristic reduction in proliferation and the concomitant induction of myeloid differentiation that is observed in MLL-rearranged and t(8;21) leukaemias upon MYB suppression is not seen in AML cells with a complex karyotype. Transcriptome analyses revealed that MYB ablation produces consensual increase of MAFB expression in MYB-dependent cells and, interestingly, the ectopic expression of MAFB could phenocopy the effect of MYB suppression. Accordingly, in silico stratification analyses of molecular data from AML patients revealed a reciprocal relationship between MYB and MAFB expression, highlighting a novel biological interconnection between these two factors in AML and supporting new rationales of MAFB targeting in MLL-rearranged leukaemias.

COVID-19 Induces Neuroinflammation and Suppresses Peroxisomes in the Brain

OBJECTIVE

Peroxisome injury occurs in the central nervous system (CNS) during multiple virus infections that result in neurological disabilities. We investigated host neuroimmune responses and peroxisome biogenesis factors during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection using a multiplatform strategy.

METHODS

Brain tissues from coronavirus disease 2019 (COVID-19) (n = 12) and other disease control (ODC) (n = 12) patients, as well as primary human neural cells and Syrian hamsters, infected with a clinical variant of SARS-CoV-2, were investigated by droplet digital polymerase chain reaction (ddPCR), quantitative reverse transcriptase PCR (RT-qPCR), and immunodetection methods.

RESULTS

SARS-CoV-2 RNA was detected in the CNS of 4 patients with COVID-19 with viral protein (NSP3 and spike) immunodetection in the brainstem. Olfactory bulb, brainstem, and cerebrum from patients with COVID-19 showed induction of pro-inflammatory transcripts (IL8, IL18, CXCL10, NOD2) and cytokines (GM-CSF and IL-18) compared to CNS tissues from ODC patients (p < 0.05). Peroxisome biogenesis factor transcripts (PEX3, PEX5L, PEX11β, and PEX14) and proteins (PEX3, PEX14, PMP70) were suppressed in the CNS of COVID-19 compared to ODC patients (p < 0.05). SARS-CoV-2 infection of hamsters revealed viral RNA detection in the olfactory bulb at days 4 and 7 post-infection while inflammatory gene expression was upregulated in the cerebrum of infected animals by day 14 post-infection (p < 0.05). Pex3 transcript levels together with catalase and PMP70 immunoreactivity were suppressed in the cerebrum of SARS-CoV-2 infected animals (p < 0.05).

INTERPRETATION

COVID-19 induced sustained neuroinflammatory responses with peroxisome biogenesis factor suppression despite limited brainstem SARS-CoV-2 neurotropism in humans. These observations offer insights into developing biomarkers and therapies, while also implicating persistent peroxisome dysfunction as a contributor to the neurological post-acute sequelae of COVID-19.

Socio-demographic and clinical characteristics of migrants to Ireland presenting with a first episode of psychosis

OBJECTIVES

When presenting with a first episode of psychosis (FEP), migrants can have different demographic and clinical characteristics to the native-born population and this was examined in an Irish Early Intervention for Psychosis service.

METHODS

All cases of treated FEP from three local mental health services within a defined catchment area were included. Psychotic disorder diagnoses were determined using the SCID and symptom and functioning domains were measured using validated and reliable measures.

RESULTS

From a cohort of 612 people, 21.1% were first-generation migrants and there was no difference in the demographic characteristics, diagnoses, symptoms or functioning between migrants and those born in the Republic of Ireland, except that migrants from Africa presented with less insight. Of those admitted, 48.6% of admissions for migrants were involuntary compared to 37.7% for the native-born population (p = 0.09).

CONCLUSIONS

First-generation migrants now make up a significant proportion of people presenting with a FEP to an Irish EI for psychosis service. Broadly the demographic and clinical characteristics of migrants and those born in the Republic of Ireland are similar, except for less insight in migrants from Africa and a trend for a higher proportion of involuntary admissions in the total migrant group.

Expression dynamics of metalloproteinases during mandibular bone formation: association with Myb transcription factor

As the dentition forms and becomes functional, the alveolar bone is remodelled. Metalloproteinases are known to contribute to this process, but new regulators are emerging and their contextualization is challenging. This applies to Myb, a transcription factor recently reported to be involved in bone development and regeneration. The regulatory effect of Myb on Mmps expression has mostly been investigated in tumorigenesis, where Myb impacted the expression of Mmp1, Mmp2, Mmp7, and Mmp9. The aim of this investigation was to evaluate the regulatory influence of the Myb on Mmps gene expression, impacting osteogenesis and mandibular bone formation. For that purpose, knock-out mouse model was used. Gene expression of bone-related Mmps and the key osteoblastic transcription factors Runx2 and Sp7 was analysed in Myb knock-out mice mandibles at the survival limit. Out of the metalloproteinases under study, Mmp13 was significantly downregulated. The impact of Myb on the expression of Mmp13 was confirmed by the overexpression of Myb in calvarial-derived cells causing upregulation of Mmp13. Expression of Mmp13 in the context of other Mmps during mandibular/alveolar bone development was followed in vivo along with Myb, Sp7 and Runx2. The most significant changes were observed in the expression of Mmp9 and Mmp13. These MMPs and MYB were further localized in situ by immunohistochemistry and were identified in pre/osteoblastic cells as well as in pre/osteocytes. In conclusion, these results provide a comprehensive insight into the expression dynamics of bone related Mmps during mandibular/alveolar bone formation and point to Myb as another potential regulator of Mmp13.

A portable primary-standard level graphite calorimeter for absolute dosimetry in clinical pencil beam scanning proton beams

Objective. To report the use of a portable primary standard level graphite calorimeter for direct dose determination in clinical pencil beam scanning proton beams, which forms part of the recommendations of the proposed Institute of Physics and Engineering in Medicine (IPEM) Code of Practice (CoP) for proton therapy dosimetry.Approach. The primary standard proton calorimeter (PSPC) was developed at the National Physical Laboratory (NPL) and measurements were performed at four clinical proton therapy facilities that use pencil beam scanning for beam delivery. Correction factors for the presence of impurities and vacuum gaps were calculated and applied, as well as dose conversion factors to obtain dose to water. Measurements were performed in the middle of 10 × 10 × 10 cm3homogeneous dose volumes, centred at 10.0, 15.0 and 25.0 g·cm-2depth in water. The absorbed dose to water determined with the calorimeter was compared to the dose obtained using PTW Roos-type ionisation chambers calibrated in terms of absorbed dose to water in60Co applying the recommendations in the IAEA TRS-398 CoP.Main results.The relative dose difference between the two protocols varied between 0.4% and 2.1% depending on the facility. The reported overall uncertainty in the determination of absorbed dose to water using the calorimeter is 0.9% (k= 1), which corresponds to a significant reduction of uncertainty in comparison with the TRS-398 CoP (currently with an uncertainty equal or larger than 2.0% (k= 1) for proton beams).Significance. The establishment of a purpose-built primary standard and associated CoP will considerably reduce the uncertainty of the absorbed dose to water determination and ensure improved accuracy and consistency in the dose delivered to patients treated with proton therapy and bring proton reference dosimetry uncertainty in line with megavoltage photon radiotherapy.

A qualitative evaluation of a telehealth healthy lifestyle intervention for people with serious mental illness

OBJECTIVES

There are high levels of nutritional and metabolic, cardiovascular, and respiratory tract diseases among people diagnosed with serious mental illness (SMI). Consequently, we developed a pragmatic, affordable nutritional and exercise intervention: Choices4Health. Due to the COVID-19 pandemic, we modified this intervention so it could be delivered online. The aim of this study was to explore the experience of participating in online Choices4Health, in a real-world clinical setting, from the perspectives of service users with SMI.

METHODS

The study aim was addressed using thematic analysis. Service users who had attended online Choices4Health, received a SMI diagnosis (defined as a schizophrenia spectrum disorder or an affective disorder), and resided in a South Dublin catchment were invited to participate. Nine participants were purposefully sampled. Semi-structured interviews were conducted by telephone. Data analysis was guided by thematic analysis procedures.

RESULTS

Six themes were generated: Being ready and not overburdened (Engagement); Gaining knowledge and implementing it (Learning and doing); Viewing the intervention as appropriate and effective (Targeted impact); Being at home with others online (Belonging); Having a positive affective attitude towards the intervention (Feeling); and Perceiving problems with intervention delivery (Recommended change).

CONCLUSIONS

Findings suggest that online Choices4Health is, broadly speaking, acceptable from a service user perspective, but that further refinement is required to address specific issues participants identified. These relate to follow-up or programme extension, technology access, in-person contact preference, and participant inclusion criteria. Further research is required into online Choices4Health efficacy, innovations to reduce digital exclusion, and managing group dynamics in telehealth interventions.

Informatics for your Gut: at the Interface of Nutrition, the Microbiome, and Technology

BACKGROUND

A significant portion of individuals in the United States and worldwide experience diseases related to or driven by diet. As research surrounding user-centered design and the microbiome grows, movement of the spectrum of translational science from bench to bedside for improvement of human health through nutrition becomes more accessible. In this literature survey, we examined recent literature examining informatics research at the interface of nutrition and the microbiome.

OBJECTIVES

The objective of this survey was to synthesize recent literature describing how technology is being applied to understand health at the interface of nutrition and the microbiome focusing on the perspective of the consumer.

METHODS

A survey of the literature published between January 1, 2021 and October 10, 2022 was performed using the PubMed database and resulting literature was evaluated against inclusion and exclusion criteria.

RESULTS

A total of 139 papers were retrieved and evaluated against inclusion and exclusion criteria. After evaluation, 45 papers were reviewed in depth revealing four major themes: (1) microbiome and diet, (2) usability,(3) reproducibility and rigor, and (4) precision medicine and precision nutrition.

CONCLUSIONS

A review of the relationships between current literature on technology, nutrition and the microbiome, and self-management of dietary patterns was performed. Major themes that emerged from this survey revealed exciting new horizons for consumer management of diet and disease, as well as progress towards elucidating the relationship between diet, the microbiome, and health outcomes. The survey revealed continuing interest in the study of diet-related disease and the microbiome and acknowledgement of needs for data re-use, sharing, and unbiased and rigorous measurement of the microbiome. The literature also showed trends toward enhancing the usability of digital interventions to support consumer health and home management, and consensus building around how precision medicine and precision nutrition may be applied in the future to improve human health outcomes and prevent diet-related disease.

An assessment of information needs and workflows for emergency service providers and caregivers of children with medical complexity

BACKGROUND

The goal of Project Austin, an initiative to improve emergency care for rural children who are medically complex (CMC), is to provide an Emergency Information Form (EIF) to their parents/caregivers, to local Emergency Medical Services, and Emergency Departments. EIFs are standard forms recommended by the American Academy of Pediatrics that provide pre-planned rapid response instructions, including medical conditions, medications, and care recommendations, for emergency providers. Our objective is to describe the workflows and perceived utility of the provided emergency information forms (EIFs) in the acute medical management of CMC.

METHODS

We sampled from two key stakeholder groups in the acute management of CMC: four focus groups with emergency medical providers from rural and urban settings and eight key informant interviews with parents/caregivers enrolled in an emergency medical management program for CMC. Transcripts were thematically analyzed in NVivo© by two coders using a content analysis approach. The thematic codes were combined into a codebook and revised the themes present through combining relevant themes and developing of sub-themes until they reached consensus.

RESULTS

All parents/caregivers interviewed were enrolled in Project Austin and had an EIF. Emergency medical providers and parents/caregivers supported the usage of EIFs for CMC. Parents/caregivers also felt EIFs made emergency medical providers more prepared for their child. Providers identified that EIFs helped provide individualized care, however they were not confident the data was current and so felt unsure they could rely on the recommendations on the EIF.

CONCLUSION

EIFs are an easy way to engage parents, caregivers, and emergency medical providers about the specifics of a care for CMC during an emergency. Timely updates and electronic access to EIFs could improve their value for medical providers.

A genome-wide relay of signalling-responsive enhancers drives hematopoietic specification

Developmental control of gene expression critically depends on distal cis-regulatory elements including enhancers which interact with promoters to activate gene expression. To date no global experiments have been conducted that identify their cell type and cell stage-specific activity within one developmental pathway and in a chromatin context. Here, we describe a high-throughput method that identifies thousands of differentially active cis-elements able to stimulate a minimal promoter at five stages of hematopoietic progenitor development from embryonic stem (ES) cells, which can be adapted to any ES cell derived cell type. We show that blood cell-specific gene expression is controlled by the concerted action of thousands of differentiation stage-specific sets of cis-elements which respond to cytokine signals terminating at signalling responsive transcription factors. Our work provides an important resource for studies of hematopoietic specification and highlights the mechanisms of how and where extrinsic signals program a cell type-specific chromatin landscape driving hematopoietic differentiation.

Improving pediatric COVID-19 vaccine uptake using an mHealth tool (MoVeUp): study protocol for a randomized, controlled trial

BACKGROUND

Coronavirus disease 2019 (COVID-19) vaccines demonstrate excellent effectiveness against infection, severe disease, and death. However, pediatric COVID-19 vaccination rates lag among individuals from rural and other medically underserved communities. The research objective of the current protocol is to determine the effectiveness of a vaccine communication mobile health (mHealth) application (app) on parental decisions to vaccinate their children against COVID-19.

METHODS

Custodial parents/caregivers with ≥ 1 child eligible for COVID-19 vaccination who have not yet received the vaccine will be randomized to download one of two mHealth apps. The intervention app will address logistical and motivational barriers to pediatric COVID-19 vaccination. Participants will receive eight weekly push notifications followed by two monthly push notifications (cues to action) regarding vaccinating their child. Through branching logic, users will access customized content based on their locality, degree of rurality-urbanicity, primary language (English/Spanish), race/ethnicity, and child's age to address COVID-19 vaccine knowledge and confidence gaps. The control app will provide push notifications and information on general pediatric health and infection prevention and mitigation strategies based on recommendations from the American Academy of Pediatrics (AAP) and the Centers for Disease Control and Prevention (CDC). The primary outcome is the proportion of children who complete COVID-19 vaccination series. Secondary outcomes include the proportion of children who receive ≥ 1 dose of COVID-19 vaccine and changes in parent/caregiver scores from baseline to immediately post-intervention on the modified WHO SAGE Vaccine Hesitancy Scale adapted for the COVID-19 vaccine.

DISCUSSION

The COVID-19 pandemic inflicts disproportionate harm on individuals from underserved communities, including those in rural settings. Maximizing vaccine uptake in these communities will decrease infection rates, severe illness, and death. Given that most US families from these communities use smart phones, mHealth interventions hold the promise of broad uptake. Bundling multiple mHealth vaccine uptake interventions into a single app may maximize the impact of deploying such a tool to increase COVID-19 vaccination. The new knowledge to be gained from this study will directly inform future efforts to increase COVID-19 vaccination rates across diverse settings and provide an evidentiary base for app-based vaccine communication tools that can be adapted to future vaccine-deployment efforts.

Review finds core outcome set uptake in new studies and systematic reviews needs improvement

OBJECTIVE

To review evidence about the uptake of core outcome sets (COS). A COS is an agreed standardized set of outcomes that should be measured and reported, as a minimum, in all clinical trials in a specific area of health or health care.

STUDY DESIGN AND SETTING

This article provides an analysis of what is known about the uptake of COS in research. Similarities between COS and outcomes recommended by stakeholders in the evidence ecosystem is reviewed, and actions taken by them to facilitate COS uptake described.

RESULTS

COS uptake is low in most research areas. Common facilitators relate to trialist awareness and understanding. Common barriers were not including in the development process all specialties who might use the COS, and the lack of recommendations for how to measure the outcomes. Increasingly, COS developers are considering strategies for promoting uptake earlier in the process, including actions beyond traditional dissemination approaches. Overlap between COS and outcomes in regulatory documents and health technology assessments is good. An increasing number and variety of organisations are recommending COS be considered.

CONCLUSION

We suggest actions for various stakeholders for improving COS uptake. Research is needed to assess the impact of these actions to identify effective evidence-based strategies.

Prediction of ADHD symptoms from prenatal data in two large population-based cohorts

Introduction

The association between low birth weight and attention problems in childhood has been replicated many times (e.g. Momany, Kamradt, & Nikolas, 2018). However birth weight is unlikely the aetiological start-point of this association, as birth weight is itself the product of many prenatal factors e.g. gestational complications, maternal toxin exposure during pregnancy and basic demographics.

Objectives

We explore (1) which prenatal factors best predict attention problems in two independant population-based cohorts of children (2) which associations, if any, are moderated by sex and (3) we report accuracy statistics of our prenatal prediction algorithm for attention problems.

Methods

Participants were children aged 9 from ABCD study from the United States (N > 9,000) and the Growing Up in Ireland (GUI) study from Ireland (N > 6,000). Selected variables included familial pscyhiatric history, maternal smoking during gestation, prescription and non-prescription drug-use during gestation and a variety of gestational complications. All interactions with sex were also included. We used 5-fold cross-validation and elastic net regression (glmnet) to identify the optimal predictors of attention problems (measured by CBCL and SDQ).

Results

Strongest predictors of attention problems in the U.S. cohort included male sex, number of drugs used during pregnancy, number of family members with a history of mental illness, and number of gestational complications. Sex interacted with several of these risks. Protective factors included being a twin/triplet, being Asian, having higher household income and higher parental education level.

Conclusions

Several risk factors for childhood attention problems were identified across both cohorts, supporting their generalizabilty. Other findings were cohort-specific.

Stress Correlates Related to Depressive Symptoms Among Young Black Men in Southern California

Black men experience higher levels of chronic stress, life stressors, and discrimination due to oppressive social and economic conditions. Black men are at greater risk of depression, but most published research on stress and depression has focused on Black people in general, Black women, or older Black men. We sought to determine whether discrimination, perceived stress, major life stress, daily hassles, and social capital were associated with depressive symptoms in young Black men. Survey data were collected from April 2010 to March 2012 in Southern California from a convenience sample of Black men (N = 201). We used two-sample t tests and one-way analysis of variance (ANOVA) to examine the association of stress correlates with depressive symptoms. Logistic regression was conducted to estimate the likelihood of reporting depressive symptoms for each significant correlate. Over half of the sample reported depressive symptoms. Health status, perceived discrimination, urban hassles, perceived stress, and neighborhood trust and safety were significantly related to depressive symptoms. Those who reported higher perceived stress had higher odds of reporting depressive symptoms, whereas lower everyday discrimination experiences were associated with lower odds of depressive symptoms. Future studies should consider examining the effectiveness of embedding coping mechanisms for stress, including perceived discrimination, in health interventions for young Black men to prevent or reduce depression.

Exploring the Readability of Ingredients Lists of Food Labels with Existing Metrics

Healthy diet and dietary behaviors are key components in prevention of chronic disease and management of chronic illness. Nutritional literacy has been associated with dietary behaviors and consumer choice of healthy foods. Nutritional literacy can be measured, for example, by examining consumer food label use, but current research focuses largely on the Nutrition Facts panel of a food product. Ingredients lists are critical for communicating food composition but are relatively unstudied in existing literature. The goal of this work is to measure the readability of ingredients lists on branded food products in the United States using existing metrics. We examined ingredients lists for all 495,646 products listed in the USDA Food Data Central database using four existing readability measures for text written in natural language. Each of these indices approximates the grade level that would be expected to comprehend a text; comparatively, patient consent forms are considered acceptable at an 8^th grade reading level or lower. We report a broad variability for in readability using different metrics: ingredients lists recorded at a 9^th grade reading level or higher to comprehend are found at rates of 16.5% (Automated Reading Index) to 74.9% (Gunning-Fog Index). Ingredients lists recorded at a 10^th grade reading level or higher to comprehend are found at rates of 84.2% (using FRE Index). These results demonstrate the need to further explore how ingredients lists can be measured for readability, both for the purposes of consumer understanding as well as for supporting future nutrition research involving text mining.

A treatment planning comparison of photon stereotactic ablative radiotherapy and proton beam therapy for the re-irradiation of pelvic cancer recurrence

BACKGROUND

Patients who experience a pelvic cancer recurrence in or near a region that received initial radiotherapy, typically have few options for treatment. Organs at risk (OAR) have often reached their dose constraint limits leaving minimal dose remaining for standard re-irradiation (reRT). However, photon based stereotactic ablative radiotherapy (SABR) has been utilised for reRT with promising initial results although meeting OAR constraints can be challenging. Proton beam therapy (PBT) could offer an advantage.

MATERIALS AND METHODS

SABR plans used for treatment for ten pelvic reRT patients were dosimetrically compared to PBT plans retrospectively planned using the same CT and contour data. PBT plans were created to match the CTV dose coverage of SABR treatment plans with V100% ≥95%. An 'as low as reasonably achievable' approach was taken to OAR tolerances with consideration of OAR dose from the initial radiation (using equivalent dose in 2 Gy fractions).

RESULTS

Dosimetric comparison of relevant OAR statistics showed a decrease in OAR dose using PBT over SABR in all patients, with equivalent target coverage. The largest statistically significant reduction was seen for the colon D0.5 cm3 with a median reduction from 13.1 Gy to 5.9 Gy. There were statistically significant dose reductions in the median dose to small bowel, sacral plexus and cauda equina.

CONCLUSION

PBT has the potential for significant dose reductions for OARs in the pelvic reRT setting compared to SABR. However, it remains unclear if the magnitude of these OAR dose reductions will translate into clinical benefit.

A protocol for the Development of Core Outcome Sets for Endodontic Treatment modalities (COSET): an international consensus process

Background

The outcome of endodontic treatment is generally assessed using a range of patient and clinician-centred, non-standardised clinical and radiographic outcome measures. This makes it difficult to synthesise evidence for systematic analysis of the literature and the development of clinical guidelines. Core outcome sets (COS) represent a standardised list of outcomes that should be measured and reported in all clinical studies in a particular field. Recently, clinical researchers and guideline developers have focussed on the need for the integration of a patient-reported COS with clinician-centred measures. This study aims to develop a COS that includes both patient-reported outcomes and clinician-centred measures for various endodontic treatment modalities to be used in clinical research and practice.

Methods

To identify reported outcomes (including when and how they are measured), systematic reviews and their included clinical studies, which focus on the outcome of endodontic treatment and were published between 1990 and 2020 will be screened. The COSs will be defined by a consensus process involving key stakeholders using semi-structured interviews and an online Delphi methodology followed by an interactive virtual consensus meeting. A heterogeneous group of key ‘stakeholders’ including patients, general dental practitioners, endodontists, endodontic teachers, clinical researchers, students and policy-makers will be invited to participate. Patients will establish, via interactive interviews, which outcomes they value and feel should be included in a COS. In the Delphi process, other stakeholders will be asked to prioritise outcomes identified from the literature and patient interviews and will have the opportunity at the end of the first round to add outcomes that are not included, but which they consider relevant. Feedback will be provided in the second round, when participants will be asked to prioritise the list again. If consensus is reached, the remaining outcomes will be discussed at an online meeting and agreement established via defined consensus rules of outcome inclusion. If consensus is not reached after the second round, a third round will be conducted with feedback, followed by the online meeting. Following the identification of a COS, we will proceed to identify how and when these outcomes are measured.

Discussion

Using a rigorous methodology, the proposed consensus process aims to develop a COS for endodontic treatment that will be relevant to stakeholders. The results of the study will be shared with participants and COS users. To increase COS uptake, it will also be actively shared with clinical guideline developers, research funders and the editors of general dental and endodontology journals.

156 Could a Cohort of Patients be Listed Directly from Video Clinic to Surgery with Assessment on Day of Surgery? The Implementation of Video Clinic in Surgical Patients During the COVID-19 Lockdown

Aim

To report the feasibly and the safety of utilizing video Clinic during the 2020 pandemic in scheduling a cohort of patients to laparoscopic cholecystectomy (LC) without the need of face-to-face assessment.

Method

A retrospective audit from May to October 2020 was conducted on patients with symptomatic biliary colic disease and selected low risk demographics who were vetted and scheduled for laparoscopic cholecystectomy through video clinic under one of the general surgeons (AC) in a large district hospital. All patients were given the option to have their face-to-face assessment on the day of surgery and if there would be any concerning signs, they would be postponed or investigated if required.

Results

33 patients agreed on the proposed option and were scheduled to LC based on virtual assessment, mean age of 42(±13) years old and 26(79%) were females. 16 (49%) patients had their surgery with average waiting time of 2.1(±1) months and mean BMI of 29.9(±7). 17 (51%) patients are pending future surgery dates. there was no cancellation based on surgery day assessment and or unexpected events intraoperatively.

Conclusions

As virtual clinics played a major role in providing healthcare services during the global pandemic, scheduling patients to surgery without face-to-face assessment was applicable and safe in selected demographics. This could have the potential of reducing waiting time, travelling costs and hospital visits. Moreover, communications with patients regarding the proposed same day assessment played a vital role in reaching a mutual agreement.

62 Evaluation of Laparoscopic Cholecystectomy with the help of AI-Video Analytics Platform

Aim

This report aims to evaluate the use of an AI video analytics platform in laparoscopic cholecystectomy (LC) based on the achievement of the critical view of safety (CVS) and to assess its ability to correctly comment on CVS.

Method

Touch surgery video platform, an AI-video based analytic tool, was screened for laparoscopic cholecystectomy in our institute and analysed from April 2019 till October 2020. Data collected by the AI included identification of the critical view of safety and time needed to achieve CVS. A reviewer graded the LC according to Nasser grading and evaluated the ability of AI to identify the CVS.

Results

66 LC were included from our video database. CVS was achieved in only 56% (37/66) in all LC videos included. Mean time spent to attend CVS from start of dissection of Calot’s triangle 16.8 (±13.6) mins. 26 (39.4%) LCs were Nasser grade 2 and 20 (30.3%) each were grade 1 and grade 3. There was no significant difference between number of CVS obtained between all grades. Time spent to achieve CVS from dissecting Calot’s triangle were the longest in grade 3 LCs (28.4±17.4 mins) with significant difference between all 3 grades. Finally, the platform correctly commented on CVS in 92.4% of the all LC videos.

Conclusions

AI video analytics can provide a useful tool to assess laparoscopic cholecystectomies and the critical view of safety. Additionally, more studies should explore the use of the platfrom and integrate the results with the clinical outcomes.

Urban American Indian Community Health Beliefs Associated with Addressing Cancer in the Northern Plains Region

American Indians residing in the Northern Plains region of the Indian Health Service experience some of the most severe cancer-related health disparities. We investigated ways in which the community climate among an American Indian population in an urban community in the Northern Plains region influences community readiness to address cancer. A Community Readiness Assessment, following the Community Readiness Model, conducted semi-structured interviews with eight educators, eight students, and eight community leaders from the American Indian community in Omaha's urban American Indian population and established the Northern Plains region community at a low level of readiness to address cancer. This study reports on a subsequent qualitative study that analyzed all 24 interview transcriptions for emergent themes to help understand the prevailing attitude of the community toward cancer. A synthesis of six emergent themes revealed that the community's perceptions of high levels of severity and barriers, paired with perceptions of low levels of susceptibility and benefits, lead to low levels of self-efficacy, all of which are reflected in minimal cues to action and little effort to address cancer. These findings, interpreted through the lens of the Health Belief Model, can inform the development of more community-based, comprehensive, and culturally appropriate approaches to address the multilevel determinants of health behaviors in relation to cancer among American Indians in the Northern Plains region.

Clozapine prescribing during follow-up of a first-episode psychosis cohort

Introduction

Of those with schizophrenia, one third develop treatment-resistant illness. Nearly 60% of these benefit from clozapine- the only antipsychotic medication licensed in this group.

Objectives

As treatment-resistant illness developed in the follow-up of a first-episode psychosis (FEP) cohort, clozapine was prescribed. This study retrospectively compared the clozapine prescribing patterns, within this cohort, to National Institute for Health and Care Excellence (NICE) guidelines. In addition, impact on hospitalisation, physical health monitoring and augmentation strategies employed following clozapine initiation were examined. Factors delaying initiation of clozapine treatment or contributing to its discontinuation were also explored.

Methods

The study included 339 individuals resident within an Irish community mental health team catchment area, referred with FEP from 1 January 2005 to 31 August 2016. Data were extracted from electronic medical records.

Results

Within the cohort, clozapine was prescribed to 32 individuals (9.4%). The mean number of adequate trials of antipsychotic prior to starting clozapine was 2.74 (SD 1.13; range 1–5). The mean time to clozapine trial was 2.1 years (SD 1.95; range 0.17–6.25). Following initiation of clozapine, mean hospital admissions per year fell from 2.3 to 0.3 (p=0.00). Mean inpatient days pre- and post-clozapine also decreased (147 vs. 53; p=0.00). In all, 18 patients ceased use of clozapine, 5 temporarily and 13 permanently.

Conclusions

Patients are being prescribed clozapine earlier than previously demonstrated. However, delayed treatment remains common, and many patients discontinue clozapine. Further research is necessary to describe and address factors which contribute to its discontinuation.

Introduction of paediatric laparoscopic cholecystectomy in Scotland: a national review of incidence, outcomes and training implications

BACKGROUND

We present a national data series to determine the incidence, outcomes and training opportunities for laparoscopic cholecystectomy among children <16yrs in Scotland as performed by paediatric surgeons.

METHODS

A retrospective cohort study was performed reviewing laparoscopic cholecystectomy performed at the three children's hospitals in Scotland. Using the National Records Scotland Database mid-year population estimates; age and sex specific annual incidence rates of laparoscopic cholecystectomy were calculated between 1998-2015. Trends in the observed case mix were tested using univariate linear regression and students t-test.

RESULTS

Between 1998-2015; 141 paediatric laparoscopic cholecystectomies were performed. The annual rate of cholecystectomy increased from 0.10/100,000 to 0.88/100,000 (p = 0.069). Sex specific incidences were identified; 0.00-0.90/100,000 (p = 0.098) in girls and 0.20-0.86/100,000 in boys (p = 0.28). Cholecystectomy was more frequent in girls (63%; p = 0.04). No major complications, defined as common bile duct injury or mortality were identified. Overall; 75% of cases were performed by consultants (n = 17 consultants, median = 5 cases, p < 0.05) and 25% by trainees.

CONCLUSION

We have demonstrated that despite a low national case load (8 laparoscopic cholecystectomies per year) paediatric surgeons have been able to perform laparoscopic cholecystectomy safely without major morbidity.

Efficacy of direct pulp capping for management of cariously exposed pulps in permanent teeth: a systematic review and meta-analysis

BACKGROUND

The outcome of vital pulp treatment after carious pulp exposure is multifactorial and related to the procedure, biomaterial and pre-operative pulpal diagnosis.

OBJECTIVES

To conduct a systematic review and meta-analysis determining the outcome of direct pulp capping (DPC) in mature permanent teeth with a cariously exposed pulp and a clinical diagnosis of reversible pulpitis, and ascertain whether the capping material influences the outcome.

METHODS

Sources: MEDLINE Ovid-SP, Cochrane Central Register of Controlled Trials (CENTRAL), International Clinical Trials Registry Platform (ICTRP), ClinicalTrials.gov, Embase and Web of Science until April 2020. Inclusion: Prospective, retrospective cohort studies and randomized trials investigating DPC outcome or comparing different capping materials after carious pulp exposure. Exclusion: Primary teeth, mechanical, traumatic or not specified pulp exposure, teeth with irreversible pulpitis or no pulpal diagnosis. Risk of bias assessed using Cochrane and modified Downs and Black quality assessment checklist. Meta-analysis on combined clinical/radiographic outcome was performed using a random effect model. Success was defined as absence of signs and symptoms of irreversible pulpitis, apical periodontitis or loss of pulp vitality.

RESULTS

Quality assessment highlighted four non-randomized studies to be of fair and five of poor quality. Four randomized trials had a high risk of bias. The pooled success rate differed based on material and follow-up. Calcium hydroxide success rate was 74% at 6-months, 65% at 1-year, 59% at 2-3 years and 56% at 4-5 years. Mineral trioxide aggregate (MTA) success was 91%, 86%, 84% and 81% at the same time points. Biodentine success was 96% at 6-months, 86% at 1 year and 86% at 2-3 years. The meta-analysis revealed MTA had better success than calcium hydroxide at 1-year (OR 2.66, 95% CI; 1.46- 4.84, P = 0.001) and 2- to 3-year follow-up (OR 2.21, 95% CI; 1.42-3.44, P = 0.0004). There was no difference between MTA and Biodentine.

DISCUSSION

These results were based on poor methodological quality studies. The effect size for of MTA vs Ca(OH)2, although modest, was consistent with narrow CI.

CONCLUSIONS

Low-quality evidence suggests a high success rate for direct pulp capping in teeth with cariously exposed pulps with better long-term outcomes for MTA and Biodentine compared with calcium hydroxide.

The patient and clinician experience of informed consent for surgery: a systematic review of the qualitative evidence

BACKGROUND

Informed consent is an integral component of good medical practice. Many researchers have investigated measures to improve the quality of informed consent, but it is not clear which techniques work best and why. To address this problem, we propose developing a core outcome set (COS) to evaluate interventions designed to improve the consent process for surgery in adult patients with capacity. Part of this process involves reviewing existing research that has reported what is important to patients and doctors in the informed consent process.

METHODS

This qualitative synthesis comprises four phases: identification of published papers and determining their relevance; appraisal of the quality of the papers; identification and summary of the key findings from each paper while determining the definitiveness of each finding against the primary data; comparison of key themes between papers such that findings are linked across studies.

RESULTS

Searches of bibliographic databases returned 11,073 titles. Of these, 16 studies met the inclusion criteria. Studies were published between 1996 and 2016 and included a total of 367 patients and 74 health care providers. Thirteen studies collected data using in-depth interviews and constant comparison was the most common means of qualitative analysis. A total of 94 findings were extracted from the primary papers and divided into 17 categories and ultimately 6 synthesised findings related to: patient characteristics, knowledge, communication, the model patient, trust and decision making.

CONCLUSIONS

This qualitative meta-aggregation is the first to examine the issue of informed consent for surgery. It has revealed several outcomes deemed important to capture by patients and clinicians when evaluating the quality of a consent process. Some of these outcomes have not been examined previously in research comparing methods for informed consent. This review is an important step in the development of a COS to evaluate interventions designed to improve the consent process for surgery.

REGISTRATION

The study protocol was registered on the international prospective register for systematic reviews (PROSPERO ID: CRD42017077101).

Seasonality of births in affective disorder in an Irish population

Seasonal variation in the births of patients with schizophrenia is a consistently replicated epidemiological finding. Few studies have investigated this phenomenon among patients with a diagnosis of affective disorder. The majority of season of birth studies have employed the chi square test for statistical analysis, a method that has been subject to some criticism. Using a Kolgomorov-Smirnov type statistic, the quarterly birth distribution of 6,646 patients with an ICD 9/10 diagnosis of affective disorder were compared to the general population. Only the births of those individuals with unipolar forms of affective disorder (n = 4,393) differed significantly from the general population, with significant excesses and deficits in the second quarter and fourth quarter respectively. These results were not altered by application of the displacement test. © 1998 Elsevier, Paris

The relationship between insight and neurological dysfunction in first-episode psychosis

Purpose

Impaired insight is commonly seen in psychosis and some studies have proposed that is a biologically based deficit. Support for this view comes from the excess of neurological soft signs (NSS) observed in patients with psychoses and their neural correlates which demonstrate a degree of overlap with the regions of interest implicated in neuroimaging studies of insight. The aim was to examine the relationship between NSS and insight in a sample of 241 first-episode psychosis patients.

Method

Total scores and subscale scores from three insight measures and two NSS scales were correlated in addition to factors representing overall insight and NSS which we created using principal component analysis.

Results

There were only four significant associations when we controlled for symptoms. “Softer” Condensed Neurological Evaluation (CNE) signs were associated with our overall insight factor (r = 0.19, P = 0.02), with total Birchwood (r = −0.24, P<0.01), and the Birchwood subscales; recognition of mental illness (r = −0.24, P<0.01) and need for treatment (r = −0.18, P = 0.02). Total Neurological Evaluation Scale (NES) and recognition of the achieved effects of medication were also weakly correlated (r = 0.14, P = 0.04).

Conclusion

This study does not support a direct link between neurological dysfunction and insight in psychosis. Our understanding of insight as a concept remains in its infancy.

A review of the current public health practice for contact tracing in relation to laryngeal TB in England 2012-2016

OBJECTIVES

Contact tracing following identification of tuberculosis (TB) is well established. However, evaluation of this activity, particularly for laryngeal TB, is limited. We compare contact tracing and outcomes in response to laryngeal TB with sputum-smear-positive pulmonary TB (ss + pTB) and consider the public health response in light of our findings.

STUDY DESIGN

This study is a comparative secondary analysis of retrospective data, extracted from TB surveillance systems, to determine differences in contact tracing process and outcomes between two groups.

METHODS

Cases of laryngeal TB (without ss + pTB) notified in England between 2012 and 2016 were selected and matched to ss + pTB controls. Number of contacts identified and screened, along with screening outcomes were gathered from local databases.

RESULTS

There were 44 laryngeal TB cases who met inclusion criteria. The median number of contacts identified per case was 3 and 4 for controls (P = 0.04). Median number of contacts screened was 3 for cases and 4 for controls. The percentage of contacts with TB was 9.7 for cases and 20.3 for controls (P < 0.01).

CONCLUSION

We observed a small difference, between case and control groups, in number of contacts identified but not number screened, indicative of a broadly similar approach to contact tracing. Conversely, the difference in screening outcomes between the groups was significant. These findings highlight a potential need to further understand infectivity of laryngeal TB; and consider possible implications for public health practice.

Knowledge and Uptake of Voting Rights By Psychiatric Inpatients in Westminster, London During the 2015 Uk General Election

Introduction

Being able to vote empowers people with mental illness to have a political voice and promotes social inclusion. Evidence shows that patients with mental illness are less likely to vote compared to the general population.

Objective

This study explores the knowledge and uptake of the voting rights of adult patients in a psychiatric hospital in the 2015 UK general election.

Aims

To understand patients’ eligibility and intentions to vote during the 2015 UK general election. To establish what assistance patients may require in order to vote.

Methods

A staff-assisted survey was undertaken in all mental health wards in the Gordon Hospital, Westminster prior to the general election in May 2015.

Results

A total of 51 surveys were returned. Seventy-five percent thought they were eligible to vote, and 47% had already registered. Of those that had not yet registered, 37% wanted staff support to do so. Fifty-seven percent of the respondents intended to vote and of those 9 out of 10 intended to vote in person. Twenty-six percent of those intending to vote identified needing assistance in this process.

Conclusions

The majority of inpatients were aware of their eligibility to vote. Over half of the respondents planned to vote, which is lower than the UK average. As 1 in 4 patients intending to vote requested support, this suggests potential barriers impacting on their ability to exercise their right.

Multidisciplinary teams can provide valuable assistance to patients in the voting process in many ways, including information provision, organisation of leave and providing staff escort.

Giri-nya-la-nha (talk together) to explore acceptability of targeted smoking cessation resources with Australian Aboriginal women

OBJECTIVES

To engage with health providers and Aboriginal women to understand what educational resources they want and need to support quit smoking attempts during pregnancy in order to develop a comprehensive evidence-based intervention.

STUDY DESIGN

Resources were developed in partnership with Aboriginal people, communities and academics with the aim to be inclusive of diverse communities. We then recruited Aboriginal women of various ages for yarning circles (focus groups) held in three Australian states to explore the acceptability of the resources and seeking further guidance as to the needs of Aboriginal women to support smoking cessation during pregnancy.

METHODS

Yarning circles were recorded and transcribed, and data were analysed independently by two researchers. Responses were coded using predetermined themes and further general inductive analysis for emergent themes.

RESULTS

Twenty-four Aboriginal women reflected on the resources they included: one pregnant woman, 15 mothers and eight elders. Predetermined themes of attraction, comprehension, cultural acceptability, graphics and layout, persuasion and self-efficacy were explored. Women suggested the following: resources need to be visually attractive and interactive to enhance self-efficacy; additional scientific content on health consequences of smoking and combining with non-pharmacological approaches to quitting.

CONCLUSION

Indigenous peoples prefer culturally targeted messages. However, developing effective Aboriginal health promotion requires more than a 'culturally appropriate' adaptation of mainstream resources. Consideration needs to be given to the diversity of Aboriginal communities when developing effective, evidence-based interventions. Aboriginal women are calling for innovative and interactive resources that enhance self-efficacy; the use of videos to explain medical and informational brochure content is well received. Requests for non-pharmacological cessation options were reported in New South Wales and Queensland and should be further explored.

31 A multi-site retrospective case note review for clinical practices of constipation in specialist palliative care settings

Background

Constipation is a common symptom for patients receiving palliative care. Whilst national clinical guidelines are available on the management of constipation for people with advanced cancer in specialist palliative care (SPC) settings questions exist around clinical practice and the extent to which the guidelines are implemented in practice. This study examine current clinical practice for management of constipation for patients with advanced cancer in SPC settings.

Methods

A multi-site retrospective case-note review was conducted consisting of 150 patient case-notes from three SPC units across the United Kingdom between August 2016 and May 2017. Descriptive statistics were used to compare clinical practices to national policy guidelines for constipation.

Results

A physical exam and bowel history was recorded for 109 patients (73%). Whilst the Bristol Stool Chart was used frequently across sites (96%) involvement of the multidisciplinary team varied. Almost a third of patient charts (27%) recorded no evidence of non-pharmacological management strategies. Pharmacological management was recorded frequently with sodium docusate or senna as the preferred laxatives across all sites however 33% of patient charts recorded no information on the titration of laxatives. There were no consistent management strategies recorded for opioid induced constipation or bowel obstruction

Conclusion

Assessment and management of constipation in SPC settings is highly variable. Variations in assessment; limited use of non-pharmacological and preventative strategies and absence of consistent strategies for opioid induced constipation or bowel obstruction are evident. Further education is needed to equip HCPs with the necessary knowledge and skills to assess and manage constipation.

32 Examining the key factors impacting on the implementation of an educational program on constipation in specialist palliative care

Introduction

Constipation is one of the most common symptoms in patients in specialist palliative care (SPC) settings and can cause considerable physical psychological and social suffering for the patient and their family. Due to the high variability in constipation assessment and management in SPC settings questions exist around how to implement an educational program in practice to address this clinical gap.

Aim

To develop and test the feasibility and acceptability of a novel educational intervention for HCPs to manage constipation experienced by people in SPC settings.

Method

Using the MRC framework for complex interventions and guided by the consolidated framework for implementation research an online resource was developed considering the content context and processes for implementation.

Results

Assessment prevention and management were identified as the core aspects. Six sessions with theoretical content application to practice and reflection through interacting with colleagues were developed in line with the best available evidence. Incentives including an educational bursary and alignment with revalidation and support from senior management champions and the research team were identified as key elements needed successful implementation. Funding IT infrastructure and attitudes to the content have been flagged as potential barriers to success.

Conclusion

A six week blended program covering the key concepts for assessment and management of constipation in palliative care has been created. Content evidence from the literature and empirical data on the preferred structure and method of delivery as well as key considerations of the contextual factors have been identified as key factors for implementation.

Childhood psychotic experiences are associated with poorer global functioning throughout adolescence and into early adulthood

BACKGROUND

Psychotic experiences (PEs) are common in childhood and have been associated with concurrent mental disorder and poorer global functioning. Little is known about the effects of childhood PEs on future functioning. We investigated the effects of childhood PEs on global functioning from childhood into early adulthood.

METHOD

Fifty-six participants from a community sample completed all three waves of the Adolescent Brain Development study (T1x¯ Age: 11.69, T2x¯ Age: 15.80 T3x¯Age: 18.80). At each phase, participants completed a clinical interview assessing for PEs, mental disorder and global function. Repeated measures models, adjusted for mental disorder and gender, were used to compare current (C-GAF) and most severe past (MSP-GAF) functioning in participants who had reported PEs in childhood and controls.

RESULTS

Participants with a history of PEs had significantly poorer C-GAF (P < 0.001) and MSP-GAF scores (P < 0.001). Poorer functioning was evident in childhood (C-GAF: P = 0.001; MSP-GAF: P < 0.001), adolescence (C-GAF: P < 0.001; MSP-GAF: P = 0.004) and early adulthood (C-GAF: P = 0.001; MSP-GAF: P = 0.076).

DISCUSSION

Children who report PEs have persistently poorer functioning through to early adulthood. The longitudinal association between childhood PEs and global functioning highlights the underlying global vulnerability in children reporting PEs, beyond what can be explained by mental disorder.

Linking Inuit Knowledge and Public Health for Improved Child and Youth Oral Health in NunatuKavut

The oral health of Inuit children in Canada has been identified as a public health crisis. Although efforts are being made to identify and address ways to deal with this crisis, current policy and program approaches are largely entrenched within the prevailing paradigm of dental science to the exclusion of Indigenous people's understandings of health. This article reports qualitative findings of a larger study aimed at identifying, understanding, and addressing rates of oral disease among children living in NunatuKavut, a cluster of small, coastal Inuit communities located in southern Labrador, Canada. Through 18 focus groups with youth (n = 86), caregivers (n = 22), and interviews with key informant (n = 13), this study begins to elucidate southern Inuit understandings of oral health. Theorized using Two-Eyed Seeing, an Indigenous approach to balancing both Indigenous and non-Indigenous understandings of the world, the findings reported here reveal 3 themes, each of which is crosscut by historical and contemporary dimensions: 1) (w)holistic conceptualizations of health are essential to good oral health, 2) achieving optimal oral health is prohibitive for Inuit communities, and 3) community-engaged oral health service delivery is needed. Our recommendations have implications for improved oral public health service delivery for Inuit communities, in that the inclusion of Inuit perspectives on oral health should form an instrumental element of oral public health service delivery. Knowledge Transfer Statement: The results of this study may be used by clinicians and oral health educators to inform approaches to oral health service delivery within the context of Indigenous communities. It may also be used by policymakers to recognize how historical and contemporary issues of colonization relate to the formation of oral health-related policies.
