Customised acoustic therapy delivered through a web-based platform-An innovative approach to tinnitus treatment.

OBJECTIVES: Customised acoustic therapy aims to moderate the neural pathways implicated in the pathophysiology of tinnitus. This study aimed to assess the efficacy of customised acoustic therapy administered via a web-based treatment platform. DESIGN: Clinical trial with prospective recruitment. Fifty-eight participants underwent 6 weeks of customised acoustic therapy. SETTING: Treatment was delivered for 2 h each day using a smartphone, tablet or computer. Treatment was integrated into usual daily activities. PARTICIPANTS: Participants with subjective tinnitus were recruited through public and private otolaryngology clinics and electronic and print media. MAIN OUTCOMES MEASURED: FiveQ, a novel 5 question tinnitus questionnaire, was measured at baseline and each week of treatment. Statistical analyses, including Wilcoxon, Mann-Whitney and mixed linear regression, were used to assess treatment efficacy and identify factors associated with treatment response. RESULTS: 39/58 participants (67.2%) had an improvement in symptom severity scores, 4 had no change (6.9%) and 15 had a decline from baseline (25.9%). Mean FiveQ scores improved by 22.9% from 40.8 (SD = 21.4) at baseline to 31.5 (SD = 21.3) following 6 weeks of treatment (p < 0.001). With the exception of the slight tinnitus group, all other groups (from mild to catastrophic) demonstrated a treatment response. Participants with low frequency tinnitus (<2000 Hz) had a significantly greater treatment response (p < 0.001). CONCLUSION: Customised acoustic therapy administered via a web-based platform demonstrated encouraging efficacy. At least mild symptoms at baseline and low frequency tinnitus were associated with a greater treatment response. Customised acoustic therapy offers accessible and efficacious tinnitus treatment, however longer term clinical studies are required to confirm the observed initial benefit is maintained.

FiveQ: A new easy-to-use validated clinical instrument for tinnitus severity.

OBJECTIVES: Tinnitus is a complex and debilitating phenomenon with potentially significant implications on quality of life. New presentations can be resource and time intensive for clinicians. Validated comprehensive tinnitus questionnaires may lack practical utility in the high-volume clinical setting. Concise, targeted questionnaires may offer an efficient alternative. This study aimed to assess the validity of the FiveQ, a novel five question construct designed to measure tinnitus severity. Convergent validity was assessed through correlating FiveQ against two comprehensive validated questionnaires, the Tinnitus Handicap Questionnaire (THQ) and Tinnitus Handicap Inventory (THI). DESIGN: Cross-sectional study with prospective recruitment. The 117 voluntarily recruited participants completed the FiveQ, THI and THQ questionnaires. Results were comparatively analysed. SETTING: Recruitment was via electronic and print media, audiology clinics and public and private otolaryngology outpatient clinics. Surveys were completed electronically. PARTICIPANTS: Members of the public aged over 18 with subjective tinnitus were invited to participate. MAIN OUTCOME MEASURED: Analyses for establishing the content validity, construct validity, internal consistency, explorary factor analysis, and responsiveness of FiveQ was performed. RESULTS: FiveQ demonstrated a high positive correlation with both the THI (r = 0.773, p < .001) and THQ (r = 0.808, p < .001). Internal consistency for FiveQ reached an acceptable threshold (Cronbach's alpha 0.86). Exploratory factor analysis demonstrated that one latent factor underlies the five items of the FiveQ. FiveQ demonstrated better responsiveness than both the THI and THQ after a 6 week interval repeat measurement. CONCLUSION: FiveQ demonstrated high-positive correlations with existing validated tinnitus questionnaires as well as acceptable internal consistency and factor analysis. The concise construct of FiveQ allows clinicians to efficiently estimate tinnitus severity, target treatment towards dominant symptoms and establish a reliable estimation of treatment response following interventions.

Suprathreshold measures of taste perception in children - Association with dietary quality and body weight.

Childhood obesity is an increasing problem in the Western world, and is affected by a multitude of interacting factors. Recent evidence suggests that taste perception may differ between obese and normal weight children. Evidence also suggests that perception of sweet and bitter taste is linked to differential food liking of various foods. To date, most studies have focused on single food items or food groups, rather than an overall view of dietary quality, and mainly on bitterness. Thus it is unclear whether taste perception is associated with dietary quality in children. Our objective was to examine the link between taste perception, dietary quality and body weight in Irish school children, in conjunction with other known influences of body weight. Taste perception was measured using the gLMS for bitter, salty and sweet stimuli. Detailed dietary intake data were collected from 525 children aged 7-13 via a 3-day diet history. Energy misreporters were identified and excluded from the dietary analyses, leaving n = 483 children. Dietary quality was assessed using Healthy Eating Index. Salivary DNA was collected and analyzed for variations in the bitter receptor gene TAS2R38. Sex differences were observed whereby intensity perception of sweetness was lower in the overweight/obese males, while no association was observed for sweet taste in the females. Despite the differences in weight status, taste perception was not associated with differences in overall dietary quality, measured via HEI score, in this cohort. Prospective cohort studies in children are necessary to better understand the association between taste intensity, food intake and weight over time.

An evaluation of portion size estimation aids: Consumer perspectives on their effectiveness.

OBJECTIVE: This qualitative study aimed to investigate consumer opinions on the usefulness of portion size estimation aids (PSEA); consumer preferences in terms of format and context for use; and the level of detail of guidance considered necessary for the effective application of PSEA. DESIGN: Six focus groups (three to eight participants per group) were conducted to elicit views on PSEA. The discussions were recorded, transcribed verbatim and analysed by two independent researchers using a template approach. SETTING: The focus groups were conducted in 2013 by an experienced moderator in various sites across the island of Ireland (three in the Republic of Ireland and three in Northern Ireland) including local leisure, community and resource centres; the home environment; and a university meeting room. PARTICIPANTS: General population, males (n = 17) and females (n = 15) aged 18-64 years old. Participants were recruited from both urban and rural locations representing a range of socio-economic groups. RESULTS: The majority of participants deemed the coloured portion pots and disposable plastic cup (household measures) to be useful particularly for the estimation of amorphous cereal products (e.g. breakfast cereals). Preferences were evident for "visual" PSEA (reference objects, household measures and food packaging) rather than 'quantities and measures' such as weighing in grams or ounces. Participants stated that PS education should be concise, consistent, from a reputable source, initiated at school age and communicated innovatively e.g. mobile app or TV advertisement. Guidance in relation to gender, age and activity level was favoured over a "one size fits all" approach. CONCLUSIONS: This study identified consumer preferences and acceptance of "visual" PSEA such as portion pots/cups to estimate appropriate PS of amorphous grain foods such as breakfast cereals, pasta and rice. Concise information from a reputable source in relation to gender, age and activity level should accompany PSEA.

Delivery of information to orthodontic patients using social media.

DesignRandomised controlled trial in a hospital setting.InterventionBoth groups were given standard verbal and written information for patients receiving orthodontic treatment. In addition, patients in the intervention group received e-mails asking them to view a specifically designed YouTube unlisted video accessible through a web link in the e-mail. All patients were administered with a baseline questionnaire at bond-up which was repeated at six weeks.Outcome measureChange in question score from baseline.ResultsSixty-seven patients were randomised (control = 34; intervention = 34). Seven patients were lost to follow-up; four in the control and three in intervention group. In all the participants watched the video 90 times. Participants in the intervention group scored, on average, almost one point higher on the second questionnaire than did those in the control group (95% CI for the difference, 0.305-1.602; P = 0.005). Ethnicity had a statistically significant effect on improvement in knowledge, but sex did not.ConclusionsPresenting audiovisual information through the YouTube web site to orthodontic patients resulted in a significant improvement in patient knowledge. Supplementation of verbal and written patient information with audiovisual information via the internet is therefore worthy of consideration.

Laser ablation electrospray ionization high-resolution mass spectrometry for regulatory screening of domoic acid in shellfish.

RATIONALE: Domoic acid (DA) is a potent neurotoxin that accumulates in shellfish. Routine testing involves homogenization, extraction and chromatographic analysis, with a run time of up to 30 min. Improving throughput using ambient ionization for direct analysis of DA in tissue would result in significant time savings for regulatory testing labs. METHODS: We assess the suitability of laser ablation electrospray ionization high-resolution mass spectrometry (LAESI-HRMS) for high-throughput screening or quantitation of DA in a variety of shellfish matrices. The method was first optimized for use with HRMS detection. Challenges such as tissue sub-sampling, isobaric interferences and method calibration were considered and practical solutions developed. Samples included 189 real shellfish samples previously analyzed by regulatory labs as well as mussel matrix certified reference materials. RESULTS: Domoic acid was selectively analyzed directly from shellfish tissue homogenates with a run time of 12 s. The limits of detection were between 0.24 and 1.6 mg DA kg-1 tissue, similar to those of LC/UV methods. The precision was between 27 and 44% relative standard deviation (RSD), making the technique more suited to screening than direct quantitation. LAESI-MS showed good agreement with LC/UV and LC/MS and was capable of identifying samples above and below 5 mg DA kg-1 wet shellfish tissue, one quarter of the regulatory limit. CONCLUSIONS: These findings demonstrate the suitability of LAESI-MS for routine, high-throughput screening of DA. This approach could result in significant time savings for regulatory labs carrying out shellfish safety testing on thousands of samples annually. © 2016 Her Majesty the Queen in Right of Canada and John Wiley & Sons Ltd.

An evaluation of portion size estimation aids: precision, ease of use and likelihood of future use.

OBJECTIVE: The present study aimed to evaluate the precision, ease of use and likelihood of future use of portion size estimation aids (PSEA). DESIGN: A range of PSEA were used to estimate the serving sizes of a range of commonly eaten foods and rated for ease of use and likelihood of future usage. SETTING: For each food, participants selected their preferred PSEA from a range of options including: quantities and measures; reference objects; measuring; and indicators on food packets. These PSEA were used to serve out various foods (e.g. liquid, amorphous, and composite dishes). Ease of use and likelihood of future use were noted. The foods were weighed to determine the precision of each PSEA. SUBJECTS: Males and females aged 18-64 years (n 120). RESULTS: The quantities and measures were the most precise PSEA (lowest range of weights for estimated portion sizes). However, participants preferred household measures (e.g. 200 ml disposable cup) - deemed easy to use (median rating of 5), likely to use again in future (all scored either 4 or 5 on a scale from 1='not very likely' to 5='very likely to use again') and precise (narrow range of weights for estimated portion sizes). The majority indicated they would most likely use the PSEA preparing a meal (94 %), particularly dinner (86 %) in the home (89 %; all P<0·001) for amorphous grain foods. CONCLUSIONS: Household measures may be precise, easy to use and acceptable aids for estimating the appropriate portion size of amorphous grain foods.

Development of a mental health smartphone app: perspectives of mental health service users.

BACKGROUND: Current mental health policy emphasises the importance of service user involvement in the delivery of care. Information Technology can have an effect on quality and efficiency of care. AIMS: The aim of this study is to gain the viewpoint of service users from a local mental health service in developing a mental health app. METHOD: A qualitative descriptive approach was used. Eight volunteers aged 18-49 years were interviewed with the aid of a semi-structured questionnaire. RESULTS: Interviewees defined a good app by its ease of use. Common themes included availability of contact information, identifying triggers, the ability to rate mood/anxiety levels on a scale, guided relaxation techniques, and the option to personalise the app. The researchers will aim to produce an app that is easily accessible, highly personalisable and will include functions highlighted as important (i.e. contact information, etc.). CONCLUSIONS: This research will assist in the development of an easy-to-use app that could increase access to services, and allow service users to take an active role in their care. In previous studies, apps were developed without the involvement of service users. This study recognises the important role of service users in this area.

A strategy to reposition the South Australian health system for quality and value.

Clinical commissioning was introduced in South Australia in 2012 to support implementation of the South Australian Health Care Plan and to achieve the desired transformation and efficiency gains required for a sustainable health system. This paper describes how the South Australian Commissioning Model was established and the process of developing the necessary culture, governance arrangements and performance management structures. Commissioning has played a key role in improving appropriateness and quality of clinical practice, resulting in reduced hospital inpatient growth and average length of stay. Despite early successes, there remain many challenges that need to be faced before value can be demonstrated consistently across the whole system.

Secular trends in reported portion size of food and beverages consumed by Irish adults.

The present analysis aimed to investigate the changes in the reported portion sizes (PS) of foods and beverages commonly consumed by Irish adults (18-64 years) from the North South Ireland Food Consumption Survey (NSIFCS) (1997-2001) and the National Adult Nutrition Survey (NANS) (2008-10). Food PS, which are defined as the weight of food (g) consumed per eating occasion, were calculated for comparable foods and beverages in two nationally representative cross-sectional Irish food consumption surveys and were published in NSIFCS and NANS. Repeated measure mixed model analysis compared reported food PS at the total population level as well as subdivided by sex, age, BMI and social class. A total of thirteen commonly consumed foods were examined. The analysis demonstrated that PS significantly increased for five foods ('white sliced bread', 'brown/wholemeal breads', 'all meat, cooked', 'poultry, roasted' and 'milk'), significantly decreased for three ('potatoes', 'chips/wedges' and 'ham, sliced') and did not significantly change for five foods ('processed potato products', 'bacon/ham', 'cheese', 'yogurt' and 'butter/spreads') between the NSIFCS and the NANS. The present study demonstrates that there was considerable variation in the trends in reported food PS over this period.

The effect of ice-slushy consumption on plasma vasoactive intestinal peptide during prolonged exercise in the heat.

The aim of this study was to determine the effect of exercise in the heat on thermoregulatory responses and plasma vasoactive intestinal peptide concentration (VIP) and whether it is modulated by ice-slushy consumption. Ten male participants cycled at 62% V̇O2max for 90min in 32°C and 40% relative humidity. A thermoneutral (37°C) or ice-slushy (-1°C) sports drink was given at 3.5mlkg(-1) body mass every 15min during exercise. VIP and rectal temperature increased during exercise (mean±standard deviation: 4.6±4.4pmolL(-1), P=0.005; and 1.3±0.4°C, P<0.001 respectively) and were moderately associated (r=0.35, P=0.008). While rectal temperature and VIP were not different between trials, ice-slushy significantly reduced heat storage (P=0.010) and skin temperature (time×trial interaction P=0.038). It appears that VIP does not provide the signal linking cold beverage ingestion and lower skin temperature in the heat.

The Irish national stroke awareness campaign: a stroke of success?

INTRODUCTION: Mass media campaigns are widely used to expose large populations to health-risk behaviour messages through routine uses of media. The Act F.A.S.T stroke campaign, which highlights the symptoms of stroke, has been endorsed globally. The aim of this study was to identify the influence of the campaign on the general public in Ireland. METHODS: Descriptive pre and post comparative study design was conducted. Phase one was conducted in April 2010 prior to the campaign. Data were collected on a cross-section of the public (n=1925) to obtain baseline information on stroke warning signs. Phase two involved collecting data from participants (n=688) 18 months after the campaign launch. RESULTS: The majority of participants from both phases were between 30 and 50 years of age. Results from phase two reported that 93% heard or saw the campaign yet only 37% could recall the campaign name or the slogan. Post the campaign over 80% recognized the warning signs of stroke. The increase in symptom recognition is evident from pre campaign to post campaign with an increase in knowledge across all the stroke symptoms. Post the campaign there was an increase of 54% of who stated that they would go straight to hospital for stroke symptoms. CONCLUSION: Findings suggest the campaign was well executed given the high percentage of participants recall and the increase in the recognition of stroke symptoms. However, the influence of the campaign in changing behaviour was not as evident. Further research is needed to examine factors that influence behaviour when a stroke strikes.

A cognitive task analysis of final year nursing students' situation awareness in simulated deteriorating patient events: A mixed methods study.

AIM: The aim of this study was to: (1) use cognitive task analysis to describe final year nursing students situation awareness in recognising, responding and escalating care of deteriorating patients in ward settings; and (2) make recommendations for training and practice. DESIGN: A mixed methods cognitive task analysis with a convergent triangulation design. METHOD: Data collection involved observations of 33 final year nursing students in simulated deteriorating patient scenarios and retrospective cognitive interviews. A process tracing technique was applied to identify the cues to deterioration participants perceived; how cue perception altered as situational demands increased; the extent that participants made connections between perceived cues and reached a situational understanding; and the factors that influenced and constrained participants situation awareness. Qualitative and quantitative findings are woven together and presented using descriptive statistics, illustrative quotations and timeline extractions. RESULTS: The median cue perception was 65.4% and 57.6% in the medical and surgical scenarios, respectively. Perception was negatively influenced by incomplete vital sign monitoring as situations escalated; limited physical assessments; passive scanning behaviours; poor task automaticity; and excessive cognitive demands. Incomplete perception, poor cue integration and underdeveloped mental models influenced situational understanding. Escalation calls did not always accurately reflect situations and a reporting mindset was evident. Clinical exposure to deteriorating patients was described as variable and opportunistic. REPORTING METHOD: The study is reported in accordance with the Good Reporting of a Mixed Methods Study (GRAMMS) checklist. PATIENT OR PUBLIC CONTRIBUTION: Patients and public were not involved in this research.

A qualitative study of psychological, social and behavioral barriers to appropriate food portion size control.

BACKGROUND: Given the worldwide prevalence of overweight and obesity, there is a clear need for meaningful practical healthy eating advice - not only in relation to food choice, but also on appropriate food portion sizes. As the majority of portion size research to date has been overwhelmingly quantitative in design, there is a clear need to qualitatively explore consumers' views in order to fully understand how food portion size decisions are made. Using qualitative methodology this present study aimed to explore consumers' views about factors influencing their portion size selection and consumption and to identify barriers to appropriate portion size control. METHODS: Ten focus groups with four to nine participants in each were formed with a total of 66 persons (aged 19-64 years) living on the island of Ireland. The semi-structured discussions elicited participants' perceptions of suggested serving size guidance and explored the influence of personal, social and environmental factors on their food portion size consumption. Audiotapes of the discussions were professionally transcribed verbatim, loaded into NVivo 9, and analysed using an inductive thematic analysis procedure. RESULTS: The rich descriptive data derived from participants highlight that unhealthy portion size behaviors emanate from various psychological, social and behavioral factors. These bypass reflective and deliberative control, and converge to constitute significant barriers to healthy portion size control. Seven significant barriers to healthy portion size control were apparent: (1) lack of clarity and irrelevance of suggested serving size guidance; (2) guiltless eating; (3) lack of self-control over food cues; (4) distracted eating; (5) social pressures; (6) emotional eating rewards; and (7) quantification habits ingrained from childhood. CONCLUSIONS: Portion size control strategies should empower consumers to overcome these effects so that the consumption of appropriate food portion sizes becomes automatic and habitual.

Assaying the efficacy of dual-antiplatelet therapy: use of a controlled-shear-rate microfluidic device with a well-defined collagen surface to track dynamic platelet adhesion.

We report the development and demonstration of an assay that distinguishes the pharmacological effects of two widely used antiplatelet therapies, aspirin (COX-1 inhibitor) and clopidogrel (P2Y12 inhibitor). Whole blood is perfused through a low-volume microfluidic device in contact with a well-characterized (ellipsometry, atomic force microscopy) acid-soluble type I collagen surface. Whole human blood treated in vitro with a P2Y12 inhibitor 2-methylthioadenosine 5'-monophosphate triethylammonium salt (2-MeSAMP) extended the time to the start of platelet recruitment, i.e., platelet binding to the collagen surface. Treatment with 2-MeSAMP also slowed the rate of aggregate buildup, with an overall reduced average platelet aggregate area after 8 min of constant blood flow. A far smaller effect was observed for in vitro treatment with aspirin, for which the rate of change of surface coverage is indistinguishable from controls. In whole blood obtained from patients under treatment with dual-antiplatelet therapy (aspirin and clopidogrel), a significant extension of time to platelet recruitment was observed along with a slowed rate of aggregate buildup and an average aggregate size approximately half that of control measurements. Differentiation of the pharmacological effects of these two well-targeted antiplatelet pathways suggests a role for this assay in determining the antiplatelet effects of these and related new therapeutics in clinical settings.

Cognitive segmentation and fluid reasoning in childhood.

The ability to solve novel complex problems predicts success in a wide range of areas. Recent research suggests that the ability to cognitively segment complex problems into smaller parts constrains nonverbal reasoning in adults. This study aimed to test whether cognitively segmenting problems improves nonverbal reasoning performance for children as it does for adults. A total of 115 children aged 6-10 years completed two versions of a modified traditional matrix reasoning task in which demands on working memory, integration, and processing speed were minimised, such that the only significant requirement was to break each problem into its constituent parts. In one version of the task, participants were presented with a traditional 2×2 Matrix and asked to draw the missing matrix item into a response box below. In a second version, the problem was broken down into its component features across three separate cells, reducing the need for participants to segment the problem. As with adults, performance was better in the condition in which the problems were separated into component parts. Children with lower fluid intelligence did not benefit more in the separated condition than children with higher fluid intelligence, and there was no evidence that segmenting problems was more beneficial for younger than older children. This study demonstrates that cognitive segmentation is a critical component of complex problem-solving for children, as it is for adults. By forcing children to focus their attention on separate parts of a complex visual problem, their performance can be dramatically improved.

Social and emotional characteristics of girls and young women with DDX3X-associated intellectual disability: a descriptive and comparative study.

DDX3X variants are a common cause of intellectual disability (ID) in females, and have been associated with autism spectrum disorder and emotional-behavioural difficulties. In this study, we compared phenotypic data for 23 females with DDX3X variants, to 23 females with ID and other genetic diagnoses. We found a wide range of adaptive, social and emotional function within the DDX3X group. Autism characteristics did not differ between DDX3X and comparison groups, while levels of anxiety and self-injurious behaviour (SIB) were significantly higher in the DDX3X group. Within the DDX3X group, adaptive function, autism characteristics, anxiety and SIB scores were positively correlated, with evidence for group-specific associations with SIB. Future work is warranted to explore the multilevel mechanisms contributing to social and emotional development in individuals with DDX3X variants.

Metabolic Syndrome in Adults Receiving Clozapine; The Need for Pharmacist Support.

People who are diagnosed with treatment resistant schizophrenia (TRS) are likely to have clozapine as a therapeutic management option. There is a high prevalence of metabolic syndrome in patients receiving clozapine. To mitigate against this, monitoring of weight, waist circumference, lipid profile, glycated haemoglobin (HbA1c), fasting blood glucose (FBG) and blood pressure (BP) is recommended. The aims of this study were to examine the prevalence of metabolic syndrome and whether any variables were correlated with its development, and to highlight any opportunities for the pharmacist to offer support. This study was conducted in an urban hospital and its associated Clozapine Clinic in Cork, Ireland. A retrospective audit assessed the prevalence of metabolic syndrome using the International Diabetes Federation (IDF) criteria. Patients were eligible for inclusion if they were aged 18 years or more, registered with the Clozapine Clinic, and had the capacity to provide informed consent. All data were entered into Microsoft® Excel ® (Microsoft Corporation) and further statistical analysis was undertaken using R, t-tests, Fisher's Exact Test and Mann-Whitney U tests as appropriate, and p ≤ 0.05 was considered statistically significant. Of 145 patients (32% female; mean age (SD) 45.3 (±11.7) years; 86.2% living independently/in family home), nearly two thirds (n = 86, 59.3%) were diagnosed with metabolic syndrome. The mean age of participants with metabolic syndrome was 44.4 years (SD = 10.8), similar to the 46.6 years (SD = 12.8) for those without. Variables that were identified to be statistically significantly associated with metabolic syndrome included waist circumference, weight, triglycerides, high density lipoprotein-cholesterol (HDL-C), BP, FBG and HbA1c. The high incidence of metabolic syndrome in this patient population highlights the need for continued physical health monitoring of these patients to ameliorate the risk of developing metabolic syndrome.

[Formula: see text]FarmApp: a new assessment of cognitive control and memory for children and young people with neurodevelopmental difficulties.

We introduce a new touchscreen-based method measuring aspects of cognitive control and memory, in children and young people with neurodevelopmental difficulties, including intellectual disability (ID). FarmApp is a gamified, tablet-based assessment tool measuring go/no-go response speed, response inhibition, visuospatial short-term memory span, and long-term memory. Here, we assessed the feasibility, validity, and utility of the method, including the benefits of measuring change in performance over two weeks. We observed that: 1) a higher proportion of participants completed FarmApp than traditional psychometric tests; 2) this proportion increased when participants had opportunity for two weeks of self-paced testing at home; 3) ADHD-relevant behavioral difficulties were associated with average go/no-go performance across all attempts, and change in go/no-go performance over time, indicating sensitivity of the method to cognitive differences with real-world relevance. We also addressed the potential utility of the FarmApp for exploring links between ID etiology and cognitive processes. We observed differences in go/no-go task between two groups of ID participants stratified by the physiological functions of associated genetic variants (chromatin-related and synaptic-related). Moreover, the synaptic group demonstrated higher degree of improvement in go/no-go performance over time. This outcome is potentially informative of dynamic mechanisms contributing to cognitive difficulties within this group. In sum, FarmApp is a feasible, valid, and useful tool increasing access to cognitive assessment for individuals with neurodevelopmental difficulties of variable severity, with an added opportunity to monitor variation in performance over time and determine capacity to acquire task competence.

Keyworker mediated enhancement of physical health in patients with first episode psychosis: A feasibility/acceptability study.

AIM: Early intervention for people experiencing first episode psychosis is a priority, and keyworkers are vital to such services. However, keyworkers' roles in addressing first episode psychosis patients' physical health are under researched. This study addresses this knowledge gap by evaluating a keyworker-mediated intervention promoting physical health among first episode psychosis patients. METHODS: The study was informed by the Medical Research Council's Framework for Complex Interventions to Improve Health. First episode psychosis participants were recruited from three Irish mental health services. The intervention was evaluated in terms of its feasibility/acceptability. RESULTS: Feasibility outcomes were mixed (recruitment rate = 24/68 [35.3%]; retention rate = 18/24 [75%]). The baseline sample was predominantly male (M:F ratio = 13:6; Med age = 25 y; IQR = 23-42 y). Common health issues among participants included overweightness/obesity (n = 11) and substance use (smoking/alcohol consumption [n = 19]). Participants' initial health priorities included exercising more (n = 10), improving diet (n = 6), weight loss (n = 7) and using various health/healthcare services. The intervention's acceptability was evidenced by the appreciation participants had for physical health keyworkers' support, as well as the healthy lifestyle, which the intervention promoted. Acceptability was somewhat compromised by a low-recruitment rate, variable linkages between keyworkers and general practitioners (GPs) and COVID-19 restrictions. CONCLUSIONS: Physical health-oriented keyworker interventions for first episode psychosis patients show promise and further evaluation of such initiatives is warranted. Future interventions should be mindful of participant recruitment challenges, strategies to enhance relationships between keyworkers and GPs, and if necessary, they should mitigate COVID-19 restrictions' impacts on care.
