Reducing the risk of criminal exploitation using multi-systemic therapy (the RESET Study): study protocol for a feasibility study and process evaluation.

BACKGROUND: Child criminal exploitation is a form of child abuse that poses a serious risk to the welfare, safety, and wellbeing of young people. Multisystemic therapy (MST) is an intensive family and community-based intervention for young people with anti-social behavioral problems, many of whom will be at risk of criminal exploitation. This protocol describes a pilot feasibility study and process evaluation, designed to examine MST for children at risk of criminal exploitation. METHODS: This pilot feasibility study and process evaluation involves two phases with associated subphases: phase 1.1 involved the collaborative refinement of the logic model adapting MST for children at risk of criminal exploitation; phase 1.2 involved pre-pilot interviews with MST therapists, families, and young people; phase 2.1 is a pilot modeling study of MST for children at risk of criminal exploitation, and; Phase 2.2 is a process evaluation that will involve interviewing stakeholders, MST therapists and employees, families, and young people. The dataset for the process evaluation will include questionnaires completed by parents and young people at baseline, mid-treatment, end of treatment, and 6 months after treatment. We will supplement these data with participant-level data linkage from MST sites and services. RESULTS: Accrual to the pilot stage of this project opened on 6th August 2021 and is due to close on 31st May 2022. We aim to publish the results of this feasibility study and process evaluation in 2023. CONCLUSIONS: The results of this feasibility study and process evaluation will inform the decision as to whether it is advisable to progress to a pilot clinical trial of MST for children at risk of criminal exploitation.

Family-systems interventions for families of people with an intellectual disability or who are autistic: a systematic review.

BACKGROUND: Family-systems interventions have been proposed as one way of supporting families of people with an intellectual disability (ID) or who are autistic. This systematic review aimed to summarise what family-systems interventions have been studied with this population, what evidence there is for their effectiveness and families' experiences of the interventions. METHODS: The review was preregistered on PROSPERO (CRD42022297516). We searched five electronic databases, identified 6908 records and screened 72 full texts. Study quality was evaluated using the Mixed Methods Appraisal Tool, and a narrative synthesis was used. RESULTS: We identified 13 eligible articles with 292 participating families. Most studies reported positive effects of the interventions on wellbeing and family relationships, and families reported positive experiences. However, research quality was poor and there are no any sufficiently powered randomised controlled trials demonstrating family-systems interventions' effectiveness for this population. CONCLUSIONS: There is a need for higher-quality research to establish whether family-systems interventions are beneficial for families of people who have an ID or who are autistic.

Early life stress and susceptibility to addiction in adolescence.

Early life stress (ELS) is a risk factor for developing a host of psychiatric disorders. Adolescence is a particularly vulnerable period for the onset of these disorders and substance use disorders (SUDs). Here we discuss ELS and its effects in adolescence, especially SUDs, and their correlates with molecular changes to signaling systems in reward and stress neurocircuits. Using a maternal separation (MS) model of neonatal ELS, we studied a range of behaviors that comprise a "drug-seeking" phenotype. We then investigated potential mechanisms underlying the development of this phenotype. Corticotropin releasing factor (CRF) and serotonin (5-HT) are widely believed to be involved in "stress-induced" disorders, including addiction. Here, we show that ELS leads to the development of a drug-seeking phenotype indicative of increased susceptibility to addiction and concomitant sex-dependent upregulation of CRF and 5-HT system components throughout extended brain reward/stress neurocircuits.

The willingness of UK adults with intellectual disabilities to take COVID-19 vaccines.

BACKGROUND: Given the much greater COVID-19 mortality risk experienced by people with intellectual disabilities (ID), understanding the willingness of people with ID to take a COVID-19 vaccine is a major public health issue. METHOD: In December 2020 to February 2021, across the United Kingdom, 621 adults with ID were interviewed remotely and 348 family carers or support workers of adults with ID with greater needs completed an online survey, including a question on willingness to take a COVID-19 vaccine if offered. RESULTS: Eighty-seven per cent of interviewees with ID were willing to take a COVID-19 vaccine, with willingness associated with white ethnicity, having already had a flu vaccine, gaining information about COVID-19 from television but not from social media, and knowing COVID-19 social restrictions rules. A percentage of 81.7% of surveyed carers of adults with ID with greater needs reported that the person would be willing to take a COVID-19 vaccine, with willingness associated with white ethnicity, having a health condition of concern in the context of COVID-19, having had a flu vaccine, being close to someone who had died due to COVID-19, and having shielded at some point during the pandemic. CONCLUSIONS: Reported willingness to take the COVID-19 vaccine is high among adults with ID in the United Kingdom, with factors associated with willingness having clear implications for public health policy and practice.

Failure to replicate a robust Down syndrome advantage for maternal well-being.

BACKGROUND: Family members caring for children with intellectual disability (ID) routinely report heightened levels of psychological distress. However, families of children with Down syndrome typically report better outcomes (known as the Down syndrome advantage). We examined whether the Down syndrome advantage would be present for maternal psychological distress, impact of caregiving, life satisfaction and perceived positive impact of the child with ID when controlling for external variables. METHODS: Mothers of children with Down syndrome (n = 111) and mothers of children with ID of mixed aetiologies (n = 196) completed measures about their own mental health, perceived impact of caregiving, life satisfaction and perceived positive impact of their child on themselves and the family unit. RESULTS: A series of group comparisons revealed small to moderate differences supporting the presence of a putative Down syndrome advantage in relation to personal maternal well-being outcomes. However, when child-related characteristics and external variables were controlled, the Down syndrome advantage was no longer present, with reduced, small effect sizes observed for all maternal outcomes. CONCLUSIONS: Initial group differences in psychological distress and life satisfaction were largely associated with family poverty, indicating that the Down syndrome advantage may be less robust than previously thought. Future research should seek to move beyond examining the existence of the putative Down syndrome advantage and focus on how families of children with Down syndrome experience family life, including longitudinal research exploring responses to life cycle and transition challenges.

Examining the Relationship Between Autism Traits and Sleep Duration as Predictors of Suicidality.

Short sleep duration is a known risk factor for suicidality in the general population, yet it is unclear how short sleep interacts with autism traits in predicting suicidality. In this cross-sectional online study, a general population sample (N = 650) completed measures assessing autism traits, suicidal ideation, and sleep duration. Moderated hierarchical regressions demonstrated that higher autism traits and shorter sleep were independent predictors of increased suicide ideation. However, sleep duration did not significantly moderate the autism trait to suicide ideation relationship. Future work should explore this relationship longitudinally using objective measures before considering intervention work to increase sleep duration in those with elevated autism traits.

Fine-tuning the photosynthetic light harvesting apparatus for improved photosynthetic efficiency and biomass yield.

Photosynthetic electron transport rates in higher plants and green algae are light-saturated at approximately one quarter of full sunlight intensity. This is due to the large optical cross section of plant light harvesting antenna complexes which capture photons at a rate nearly 10-fold faster than the rate-limiting step in electron transport. As a result, 75% of the light captured at full sunlight intensities is reradiated as heat or fluorescence. Previously, it has been demonstrated that reductions in the optical cross-section of the light-harvesting antenna can lead to substantial improvements in algal photosynthetic rates and biomass yield. By surveying a range of light harvesting antenna sizes achieved by reduction in chlorophyll b levels, we have determined that there is an optimal light-harvesting antenna size that results in the greatest whole plant photosynthetic performance. We also uncover a sharp transition point where further reductions or increases in antenna size reduce photosynthetic efficiency, tolerance to light stress, and impact thylakoid membrane architecture. Plants with optimized antenna sizes are shown to perform well not only in controlled greenhouse conditions, but also in the field achieving a 40% increase in biomass yield.

The personality disorder patient pathway: Service user and clinical perspectives.

AIMS: There have been recent policy developments and research into care provision for service users with personality disorder. However, few studies have focused on service user and staff perspectives on how services could be improved. METHODS: A qualitative study was undertaken in the UK between 2016 and 2017. We conducted six focus groups with clinicians in mental health services with experience of working with people with personality disorder. Using an online survey, we asked current and past service users with personality disorder to describe their experiences of mental health services and make recommendations for improvements. A thematic analysis was conducted. RESULTS: Forty-five clinicians participated in the focus group and 131 service users contributed to the online survey. The main areas of concern identified by both staff and patients were the diagnosis of personality disorder, the absence of a coherent care pathway, access to psychological treatment and staff training. CONCLUSIONS: The care pathway for individuals with personality disorder is unclear to clinicians and service users, and elements of the pathway are disjointed and not working as effectively as they could. Guidelines recommended by National Institute for Health and Care Excellence are not being followed. Specialist psychological interventions should be available to ensure consistent and stable care provision. © 2019 John Wiley & Sons, Ltd.

The osmotic effect of hyper-saline hydraulic fracturing fluid on rainbow trout, Oncorhynchus mykiss.

Flowback and produced water (FPW) is a complex, often brackish, solution formed during the process of hydraulic fracturing. Despite recent findings on the short-term toxicity of FPW on aquatic biota, longer-term impacts of FPW on fish have not yet been investigated and the mechanisms of chronic effects remain unknown. The aim of the present study was to observe the effect of a diluted FPW on ionoregulatory endpoints in the rainbow trout Oncorhynchus mykiss, following a 28-d sub-chronic exposure. A salinity-matched control solution (SW), recreating the salt content of the FPW, was used to differentiate the specific effect of the salts from the effects of the other FPW components (i.e. organics and metals). Overall, fish ionoregulation was not impacted by the chronic exposure. An accumulation of strontium (Sr) and bromide (Br) occurred in the plasma of the FPW-exposed fish only, however no change of plasma ions (Na, K, Cl, Ca, Mg) was observed in SW- or FPW-exposed fish. Similarly, exposures did not alter branchial activity of the osmoregulatory enzymes sodium/potassium ATPase and proton ATPase. Finally, FPW exposure resulted in modifications of gill morphology over time, with fish exposed to the fluid displaying shorter lamellae and increased interlamellar-cell mass. However, these effects were not distinct from morphological changes that also occurred in the gills of control groups.

Who's challenging who training for staff empathy towards adults with challenging behaviour: cluster randomised controlled trial.

BACKGROUND: One in five adults with intellectual disabilities (ID) known to services display challenging behaviours (CBs), and these individuals are at risk for restrictive practices and poor care. Staff attitudes may contribute to the development and/or maintenance of CBs. We investigated the effectiveness of co-produced Who's Challenging Who? training delivered by people with ID to staff. METHOD: This study involved a cluster randomised controlled trial (RCT) of Who's Challenging Who? training with follow-up at six and 20 weeks post-randomisation. PARTICIPANTS: two staff from each of 118 residential care settings for adults with ID at least one of whom displayed aggressive CB. PRIMARY OUTCOME: Self-reported Staff Empathy for people with Challenging Behaviour Questionnaire. ANALYSIS: intention to treat of all randomised settings. ISCRTN registration: ISRCTN53763600. RESULTS: 118 residential settings (including 236 staff) were randomised to either receive training (59 settings) or to receive training after a delay (59 settings). The primary analysis included data from 121 staff in 76 settings (51% of staff, 64% of settings). The adjusted mean difference on the transformed (cubed) Staff Empathy for people with Challenging Behaviour Questionnaire score at the primary end point was 1073.2 (95% CI: -938.1 to 3084.5, P = 0.296) in favour of the intervention group (effect size Cohen's d = .19). CONCLUSIONS: This is the first large-scale RCT of a co-produced training course delivered by people with ID. Findings indicated a small positive (but statistically non-significant) effect on increased staff empathy at 20 weeks, and small to moderate effects for staff reported secondary outcomes in favour of the intervention group.

A systematic review of stakeholder views of selection methods for medical schools admission.

BACKGROUND: The purpose of this paper is to systematically review the literature with respect to stakeholder views of selection methods for medical school admissions. METHODS: An electronic search of nine databases was conducted between January 2000-July 2014. Two reviewers independently assessed all titles (n = 1017) and retained abstracts (n = 233) for relevance. Methodological quality of quantitative papers was assessed using the MERSQI instrument. The overall quality of evidence in this field was low. Evidence was synthesised in a narrative review. RESULTS: Applicants support interviews, and multiple mini interviews (MMIs). There is emerging evidence that situational judgement tests (SJTs) and selection centres (SCs) are also well regarded, but aptitude tests less so. Selectors endorse the use of interviews in general and in particular MMIs judging them to be fair, relevant and appropriate, with emerging evidence of similarly positive reactions to SCs. Aptitude tests and academic records were valued in decisions of whom to call to interview. Medical students prefer interviews based selection to cognitive aptitude tests. They are unconvinced about the transparency and veracity of written applications. Perceptions of organisational justice, which describe views of fairness in organisational processes, appear to be highly influential on stakeholders' views of the acceptability of selection methods. In particular procedural justice (perceived fairness of selection tools in terms of job relevance and characteristics of the test) and distributive justice (perceived fairness of selection outcomes in terms of equal opportunity and equity), appear to be important considerations when deciding on acceptability of selection methods. There were significant gaps with respect to both key stakeholder groups and the range of selection tools assessed. CONCLUSIONS: Notwithstanding the observed limitations in the quality of research in this field, there appears to be broad concordance of views on the various selection methods, across the diverse stakeholders groups. This review highlights the need for better standards, more appropriate methodologies and for broadening the scope of stakeholder research.

Desires versus reality of medical and health science summer student research opportunities.

BACKGROUND: Medical and health science students are increasingly becoming involved in research throughout their undergraduate education. However, the quality of student research outcomes has recently come into question. METHODS: A cross-sectional online survey of Irish medical and health science student who received a summer student research grant in 2014 and 2015. RESULTS: Of 56 respondents (40.6% response rate), increasing competitiveness for future career opportunities was the highest rated motivational factor for pursuing research. Respondents were most often involved in analysing data (n = 51; 91.1%) and collecting data (n = 46; 82.1%). Respondents most often identified that they would have liked to be involved in coming up with research question (n = 34; 60.7%), while in reality, they were least commonly involved in that aspect (n = 14; 25.0%). CONCLUSION: Despite the desire by summer research students to be involved in early components of research project design, this only occasionally occurs. Summer student research programs should explore the possibility of early involvement of students in the research design phase.

Research amongst Irish surgical trainees: what's the trend?

INTRODUCTION: A high publication rate for surgical trainees is considered a prerequisite for progression to Higher Specialist Training (HST). This rate has arguably been decreased by the formation of a new 'run-through' training pathway. We aim to quantify the number of publications that the 'new' pathway trainees have attained compared to the 'old' pathway trainees. We further aim to compare the H-index and average citations between General Surgery (GS) and Trauma and Orthopaedic (T&O) trainees. METHODS: Publications from old pathway trainee years 2007-2014 (T&O n = 59, GS n = 64) were compared with new pathway trainees from 2015 to 2016 (T&O n = 11, GS n = 12). H-index and average citations were also compared for trainees commencing HST years 2007-2009. Statistical analysis involved D'Agostino normality testing. An unpaired Student's t test ± Welch's correction was utilised for parametric data and a Mann-Whitney U test for non-parametric data. RESULTS: The average number of publications attained by the old pathway T&O trainee was 4.2 ± 3.1 and was 3.1 ± 2.4 for the new trainee. Old GS trainees had an average of 6.5 ± 3.3 publications prior to HST with new GS trainees having an average of 3.7 ± 2.8 publications. The average H-index attained for GS trainees on completion of the HST pathway was 5.1 ± 3.2 and 4.6 ± 2.4 for T&O trainees. CONCLUSION: There has been a significant decrease in publication rates between new and old GS pathways. No significant changes were identified between new and old T&O pathways. There was no difference between H-index and average citations between specialties.

Suicide by mental health in-patients under observation.

BACKGROUND: Observations in psychiatric in-patient settings are used to reduce suicide, self-harm, violence and absconding risk. The study aims were to describe the characteristics of in-patients who died by suicide under observation and examine their service-related antecedents. METHOD: A national consecutive case series in England and Wales (2006-2012) was examined. RESULTS: There were 113 suicides by in-patients under observation, an average of 16 per year. Most were under intermittent observation. Five deaths occurred while patients were under constant observation. Patient deaths were linked with the use of less experienced staff or staff unfamiliar with the patient, deviation from procedures and absconding. CONCLUSIONS: We identified key elements of observation that could improve safety, including only using experienced and skilled staff for the intervention and using observation levels determined by clinical need not resources.

Controlling wettability of PECVD-deposited dual organosilicon/carboxylic acid films to influence DNA hybridisation assay efficiency.

Herein, plasma polymerisation of a dual-layer tetraethyl orthosilicate (TEOS) and acrylic acid (AA) film under a specific recipe is performed. Newly deposited films are found to retain a weakly-bound soft layer of partially polymerised acrylic acid (wbAA), which can be ultimately removed by washing. However, when on the surface, this soft layer is shown to be influential in manipulating the properties of a robust covalently-bound AA (cbAA) underlayer when treated appropriately. Specifically, treatment of the as-deposited dual-layer TEOS/AA films via timed incubation in a humidity-controlled environment results in changes in the water contact angle (WCA) of the cbAA, and ultimately the surface of the TEOS/AA, enabling tuning of the wettability of the acrylic acid layer. Through the use of a controlled incubation environment of the TEOS/AA, followed by washing, we have demonstrated that carboxylic-acid containing surfaces with a WCA between 85° and 10° can be routinely generated, using basic apparatus and simple methodology. Moreover, these surfaces not only retain their AA functionality, demonstrated by covalent-linking of amine-terminated single-stranded DNA, but also strongly inhibit non-specific binding of the DNA strands. The efficiency of these surfaces to be used in DNA direct-binding hybridisation assays has been demonstrated, with limits of detection of 1.11 and 1.66 nM being measured.

Accrual to Cancer Clinical Trial.

Accrual to cancer clinical trials (CCT) is imperative to safeguard continued improvement in cancer outcomes. A retrospective chart review was performed of patients (n=140) starting a new anti-cancer agent in a north Dublin cancer centre. This review was performed over a four-month period, beginning in November 2015. Only 29% (n=41) had a CCT option. The overall accrual rate to CCT was 5% (n=7), which is comparable to internationally reported figures. The main reasons for failure to recruit to CCT included the lack of a CCT option for cancer type (n=30, 23%), stage (n=25, 19%), and line of treatment (n=23, 17%). Over the last decade, the rate of accrual to CCTs has in fact doubled and the number of trials open to recruitment has tripled. Ongoing governmental and philanthropic support is necessary to continue this trend to further expand CCT patient options with a target accrual rate of 10%.

Ultrasensitive microarray bioassays using cyanine5 dye-doped silica nanoparticles.

Herein we report the use of high brightness Cyanine5-doped silica nanoparticles (NPs) for the detection of antibodies or DNA in microarray bioassays. NP labels showed negligible non-specific binding, greater sensitivity and lower limits of detection when compared to free dye-labelled biomolecules. Moreover, the spotted microarrays used in this study required low NP and antibody concentrations to generate large data sets with improved statistical accuracy. These NPs have significant potential for use in biosensing for disease detection.

Irish Medical Students Understanding of the Intern Year.

Upon completion of medical school in Ireland, graduates must make the transition to becoming interns. The transition into the intern year may be described as challenging as graduates assume clinical responsibilities. Historically, a survey of interns in 1996 found that 91% felt unprepared for their role. However, recent surveys in 2012 have demonstrated that this is changing with preparedness rates reaching 52%. This can be partially explained by multiple initiatives at the local and national level. Our study aimed evaluate medical student understanding of the intern year and associated factors. An online, cross-sectional survey was sent out to all Irish medical students in 2013 and included questions regarding their understanding of the intern year. Two thousand, two hundred and forty-eight students responded, with 1,224 (55.4%) of students agreeing or strongly agreeing that they had a good understanding of what the intern year entails. This rose to 485 (73.7%) among senior medical students. Of junior medical students, 260 (42.8%) indicated they understood what the intern year, compared to 479 (48.7%) of intermediate medical students. Initiatives to continue improving preparedness for the intern year are essential in ensuring a smooth and less stressful transition into the medical workforce.

Multivalent linkers for improved covalent binding of oligonucleotides to dye-doped silica nanoparticles.

This paper describes the fabrication of oligonucleotide-coated Cy5-doped silica nanoparticles using a combination of multivalent linkers and their use in surface-based DNA sandwich hybridization assays. Dipodal silane is introduced as a means to fabricate amine-coated silica nanoparticles and its advantages compared to monopodal silanes are discussed. The use of dipodal silane in conjunction with three different polymer linkers (oxidized dextran, linear and 8-arm polyethylene glycol (PEG)) to immobilize single-stranded DNA to Cy5-doped nanoparticles is investigated and dynamic light scattering measurements and Fourier transform infrared spectroscopy are used to follow the progression of the functionalization of the nanoparticles. We observe a significant improvement in the binding stability of the single-stranded DNA when the dipodal silane and 8-arm PEG are used in combination, when compared to alternative conjugation strategies. Both 8mer and 22mer oligonucleotides are securely conjugated to the high-brightness nanoparticles and their availability to hybridize with a complementary strand is confirmed using solution-based DNA hybridization experiments. In addition, a full surface-based sandwich assay demonstrates the potential these nanoparticles have in the detection of less than 500 femtomolar of a DNA analogue of micro RNA, miR-451.
