Multicomponent perinatal breastfeeding support in women with BMI >25: The Latch On multi-centre randomised trial.

OBJECTIVE: To investigate the effectiveness of a multicomponent breastfeeding support intervention on breastfeeding prevalence at 3 months among women with a body mass index (BMI) >25 kg/m2. DESIGN: Multicentre multicomponent randomised controlled trial. SETTING: Four maternity centres in Ireland. POPULATION: A total of 225 primiparous women and their nominated support partners. Participants were aged 18 years and over, with BMI ≥25 kg/m2, carrying a singleton pregnancy and without contraindication for breastfeeding. METHODS: The intervention included an antenatal group breastfeeding education session for participants and their support partners, followed by a planned postnatal breastfeeding assessment and telephone support for up to 6 weeks by a lactation consultant. MAIN OUTCOME MEASURES: Any breastfeeding at 3 months postpartum. RESULTS: Any breastfeeding prevalence was 68.7% (n = 68) in the intervention group and 62.1% (n = 59) in the control group at 3 months postpartum (odds ratio 1.33, 95% confidence interval 0.72-2.46, p = 0.36). Any and exclusive breastfeeding rates did not significantly differ at any other time point. More women in the control group accessed support from private lactation consultants (intervention 23.5% [n = 12], control 45.3% [n = 24], p = 0.02). CONCLUSIONS: The control group had higher than expected breastfeeding rates, and the study found no evidence of effect on the primary outcome. Providing comprehensive education and support for women intending to breastfeed remains of paramount importance.

Quality of life, cognitive and behavioural impairment in people with motor neuron disease: a systematic review.

PURPOSE: Motor neuron disease (MND) is a neurodegenerative disease, progressively impacting function and self-perceived quality of life (QoL). Up to 50% of people with MND can present with cognitive and behavioural impairment, with an associated increase in caregiver burden or strain. However, there has been no systematic exploration of the relationship between QoL and cognitive or behavioural impairment in MND. The aim was to determine if there is a relationship between QoL and cognitive/behavioural impairment in MND, while also supplementarily looking to determine the types of cognitive/behavioural and QoL measures utilised in these studies. METHODS: A systematic search was performed across multiple databases (PsychINFO, Embase, Medline, AMED) for research published up to the date of February 22, 2023. Studies utilising quantitative methods of measuring QoL, cognitive/behavioural functioning/impairment were included. Findings examining relationships between QoL-cognitive/behavioural impairment were extracted and synthesised. RESULTS: A total of 488 studies were identified, with 14 studies included in the systematic review. All 14 studies were observational (11 cross-sectional, 3 longitudinal). 13 studies utilised MND non-specific measures, particularly in relation to QoL and cognitive impairment. Of 8 studies measuring behavioural impairment 62.5% (N = 5) found either a lower QoL difference or association. Only 33.3% (N = 4) of 12 studies measuring cognitive impairment found a lower QoL difference or association. CONCLUSIONS: This systematic review shows that behavioural impairment may have an impact on QoL in MND. There is variability in types of assessments used to measure QoL and also cognitive/behavioural impairment, most of which are disease-non-specific. Recommendations for future research are to use comprehensive disease-specific, multidomain measures to further elucidate the QoL-cognitive/behavioural impairment relationship.

More than clean teeth! Identifying factors that contribute to the development of early childhood caries.

The updated systematic review by Khan et al. reviews the evidence surrounding the possible factors that could contribute to the development of early childhood caries (ECC) in children of a particular age group. This follows a previously published systematic review across 1997-2017. These factors can then be used for the development of a Caries Risk Assessment (CRA) tool. DATA SOURCES: This review aimed to identify established and updated evidence-based factors that could contribute to a child's development of Early Childhood Caries (ECC). Four online databases were used to source evidence including the Cochrane Library, EMBASE, MEDLINE, and Scopus. STUDY SELECTION: The data search selected studies published between 2017 and 2021. Three specific terms were used to search: Dental Caries, Children, and Risk Assessment. There were three teams involved in data collection, two teams then reviewed selected articles. Exclusion criteria included any duplicate studies, commentaries, and editorials. Inclusion criteria included only randomised control trials and cohort studies. Selected studies must include children younger than 72 months, define the demographics, their clinical characteristics, and have clear follow-up of the patients involved. Commonly identified factors that were mentioned in multiple studies were then collected and assigned strength depending on the evidence measured using ratios. These could then be utilised to form a draft Caries Risk Assessment tool. DATA EXTRACTION AND SYNTHESIS: 512 abstracts and 52 articles were screened, having matched the criteria set. Extraction of the data was completed under four headings: the child's age at the time of study (in years/months), risk predictors, the outcome, and the quality of the evidence presented. The GRADE system was then employed to separate the studies into high, moderate, low, and very low categorisation. Eventually, 22 new studies were included that would build on the original 25 articles that were identified in the previous systematic review. RESULTS: The most defining factors across the most recent systematic reviews in 2021 highlighted behavioural factors such as toothbrushing quality - parental supervision, frequency, and fluoride exposure. Specifically, the presence of plaque was used as a marker for oral hygiene evaluation. Dietary history included snacking frequency and, controversially, baby-toddler breastfeeding patterns. However, this does not take into consideration the dental impact - mainly the frequency or timing of breastfeeding (e.g. overnight). The review emphasises the importance of consideration of socio-economic factors though this may be a difficult topic of discussion if families are struggling i.e. household income and education level of parents or guardians. There is also mention of factors that do not have a significant evidence base such as the child's gender, ethnicity, and parental smoking status. CONCLUSION: In conclusion, the factors found to be relevant in the development of ECC were the child's age, toothbrushing quality/plaque control, parental involvement in toothbrushing, fluoride exposure, pattern of dental attendance, dietary sugar exposure, and habits, clinically carious active lesion presence, the oral bacterial composition (Streptococcus mutans presence) and the socio-economic status of the child and their family. Though the review encourages identification of the caries risk factors in the mentioned groups, separated by both dental and non-dental professionals, ideally the aim would be to create a holistic care approach for management and signposting.

Undergraduate paramedicine students' experiences of feedback during clinical placement on-road: A scoping review.

Feedback on performance enhances student confidence and clinical skills and promotes safe clinical practice. Experiences of feedback are well documented across many health disciplines; however, less is known about paramedicine students' experiences of feedback on-road in an emergency ambulance. The aim of this scoping review was to identify what is known about paramedicine students' experiences of feedback during clinical placement on-road in an emergency ambulance. A review of studies between 2000 and 2021 was undertaken, guided by the Joanna Briggs Institute Methodology for JBI Scoping Reviews and reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Extension for Scoping Reviews. Databases included CINAHL, EMBASE, EBSCO, MEDLINE, Web of Science, Cochrane, ERIC (ProQuest), ProQuest (Nursing and Allied Health), Trove, and Open Accessd Theses and Dissertations. Three studies were identified. Feedback is valued by paramedicine students; however, it can be personal and destructive in nature. Paramedics are enthusiastic and supportive and provide clear feedback. Paramedics face challenges supervising students and may lack preparation to provide feedback. There is limited evidence on paramedicine students' experiences of feedback during clinical placement. Further exploration is needed to gain further understanding.

High burden of childhood tuberculosis in migrants: a retrospective cohort study from the Thailand-Myanmar border.

BACKGROUND: Tuberculosis (TB) is a leading cause of morbidity and mortality in children but epidemiological data are scarce, particularly for hard-to-reach populations. We aimed to identify the risk factors for unsuccessful outcome and TB mortality in migrant children at a supportive residential TB programme on the Thailand-Myanmar border. METHODS: We conducted retrospective analysis of routine programmatic data for children (aged ≤ 15 years old) with TB diagnosed either clinically or bacteriologically between 2013 and 2018. Treatment outcomes were described and risk factors for unsuccessful outcome and death were identified using multivariable logistic regression. RESULTS: Childhood TB accounted for a high proportion of all TB diagnoses at this TB programme (398/2304; 17.3%). Bacteriological testing was done on a quarter (24.9%) of the cohort and most children were diagnosed on clinical grounds (94.0%). Among those enrolled on treatment (n = 367), 90.5% completed treatment successfully. Unsuccessful treatment outcomes occurred in 42/398 (10.6%) children, comprising 26 (6.5%) lost to follow-up, one (0.3%) treatment failure and 15 (3.8%) deaths. In multivariable analysis, extra-pulmonary TB [adjusted OR (aOR) 3.56 (95% CI 1.12-10.98)], bacteriologically confirmed TB [aOR 6.07 (1.68-21.92)] and unknown HIV status [aOR 42.29 (10.00-178.78)] were independent risk factors for unsuccessful outcome. HIV-positive status [aOR 5.95 (1.67-21.22)] and bacteriological confirmation [aOR 9.31 (1.97-44.03)] were risk factors for death in the secondary analysis. CONCLUSIONS: Children bear a substantial burden of TB disease within this migrant population. Treatment success rate exceeded the WHO End TB target of 90%, suggesting that similar vulnerable populations could benefit from the enhanced social support offered by this TB programme, but better child-friendly diagnostics are needed to improve the quality of diagnoses.

Efficacy and safety of sotagliflozin in patients with type 2 diabetes and severe renal impairment.

AIMS: To assess the efficacy and safety of sotagliflozin, a dual inhibitor of sodium-glucose cotransporter-1 and -2, in adults with type 2 diabetes (T2D) and stage 4 chronic kidney disease (CKD4). MATERIALS AND METHODS: This 52-week, phase 3, randomized (1:1:1), placebo-controlled trial evaluated sotagliflozin 200 mg and sotagliflozin 400 mg once daily in 277 patients with T2D and estimated glomerular filtration rate (eGFR) 15 to 30 mL/min/1.73 m2 . The primary endpoint was glycated haemoglobin (HbA1c) reduction with sotagliflozin 400 mg versus placebo at 26 weeks. A hierarchical statistical testing approach was used. RESULTS: The baseline mean HbA1c was 65 ± 12 mmol/mol (8.1% ± 1.1%), systolic blood pressure (SBP) was 144 ± 15 mmHg, and eGFR was 24 ± 4 mL/min/1.73m2 . Placebo-adjusted changes with sotagliflozin 400 mg were -3 mmol/mol (-0.3%; 95% confidence interval -7 to 0.6 [-0.6 to 0.05]; P = 0.096) and -8 mmol/mol (-0.7%; -13 to -3 [-1.2 to -0.2]; P = 0.003) in HbA1c at Weeks 26 and 52, respectively, -1.5 kg (-3.0 to -0.1) in body weight at Week 26, -5.4 mmHg (-9.4 to -1.3) in SBP at Week 12, and -0.3 mL/min/1.73 m2 (-2.1 to 1.6; P = 0.776) in eGFR at Week 52. Over 52 weeks, 11.8%, 5.4% and 3.3% of patients receiving placebo and sotagliflozin 200 and 400 mg, respectively, required rescue therapy for hyperglycaemia. Adverse events (AEs) occurred in 82.8%, 86.2% and 81.1% of patients and serious cardiovascular AEs occurred in 12.9%, 3.2% and 4.4% of patients in the placebo and sotagliflozin 200 and 400 mg groups, respectively. CONCLUSIONS: After 26 weeks, HbA1c reductions with sotagliflozin were not statistically significant versus placebo in adults with T2D and CKD4. The 52-week safety profile was consistent with results of the SCORED outcomes trial (NCT03242018).

Choosing Performance-Based Outcome Measures of Daily Living Skills and Socialization for Clinical Trials in Autistic Children.

IMPORTANCE: Robust and psychometrically sound performance-based outcome measures are needed for clinical trials of occupational therapy interventions for children with autism. OBJECTIVE: To demonstrate a systematic approach for choosing psychometrically sound performance-based outcome measures of daily living skills and socialization for use in clinical trials of occupational therapy interventions for children with autism. DESIGN: Rapid literature review to identify appropriate measures for studies with this population followed by quality indicator ratings and a nominal group process. SETTING: University. PARTICIPANTS: Four experts in autism and pediatric outcome measurement. Outcomes and Measures: Twenty-one outcome measures of daily living skills and socialization were identified and reviewed. RESULTS: Seven measures met the inclusion criteria. The Assessment of Motor and Process Skills and the Evaluation of Social Interaction-Second Edition, received the highest ratings and group consensus. Several other measures were also scored highly. CONCLUSIONS AND RELEVANCE: Careful assessment of psychometric properties is an important component of choosing outcome measures for a clinical trial, but burden of assessment and study objectives are important considerations. What This Article Adds: This project demonstrates use of a systematic process for choosing outcome measures for a planned clinical trial.

Uterine adenosarcoma: an analysis on management, outcomes, and risk factors for recurrence.

OBJECTIVES: Uterine adenosarcoma is a rare malignancy with little data on optimal management. We aimed to clarify the impact of adjuvant therapy in patients with uterine adenosarcoma and identify risk factors for recurrence and death. METHODS: We performed a retrospective review of patients undergoing primary evaluation and treatment for uterine adenosarcoma at a single institution from July 1982 through December 2011. Univariate and multivariate analyses were used to identify prognostic factors for progression-free survival (PFS) and overall survival (OS). RESULTS: We identified 100 patients with uterine adenosarcoma, and 74 patients met the inclusion criteria. On multivariate analysis, sarcomatous overgrowth (SO) and lymphovascular space invasion (LVSI) were predictors of worse PFS and OS. Median PFS and OS were 29.4 and 55.4 months for patients with SO, compared to 105.9 and 112.4 months for patients without SO (PFS HR 2.58, 95% CI 1.37-4.84, p=0.003; OS HR 2.45, 95% CI 1.26-4.76, p=0.008). Among patients with stage I disease, 17 of 22 patients (77%) with SO and 8 of 37 patients (22%) without SO had a recurrence (p<0.001). Among patients with stage I disease with SO, adjuvant therapy appeared to be associated with longer PFS and OS, but these differences were not statistically significant (PFS, 46.7 vs. 29.4 months, p=0.28; OS, 97.3 vs. 55.4 months, p=0.18). CONCLUSION: In patients with uterine adenosarcoma, the presence of SO or LVSI confers a higher risk of recurrence. We did not identify an optimal treatment strategy for patients with SO, but adjuvant therapy may be associated with prolonged PFS.

Clinician Opinions Regarding the Usefulness of the BOSA for ASD Assessment in a Service for Children Aged Under 12 Years.

The COVID-19 pandemic and the subsequent social distancing policies forced healthcare teams to drastically alter the way they deliver services. This was particularly challenging for clinicians involved in diagnosing autism spectrum disorder (ASD), as assessment tools and methods required face-to-face social interactions between clinicians and children. To address this, the Brief Observation of Symptoms of Autism (BOSA) was developed to ensure that people suspected of ASD can receive diagnostic assessments during the pandemic. This project aimed to explore clinicians' opinions on the BOSA, particularly regarding the usefulness of the assessment for clinicians to clarify diagnostic outcomes of ASD assessments. Both quantitative and qualitative data was gathered within an NHS community paediatric team. This included a questionnaire for clinicians to complete, and data from the BOSA assessments done in the service. Thematic analysis and descriptive statistics revealed that many clinicians felt that the BOSA can be beneficial in certain cases, such as selective mutism, and found the BOSA particularly helpful for observing parent-child interactions. These findings highlighted important information that the Autism Diagnostic Observation Schedule Second Edition (ADOS-2) does not give opportunities to observe. Clinicians reported that at times, the BOSA materials, brevity and parental administration created barriers to gathering information for diagnostic decisions. As may be expected, clinicians showed a clear preference for the more familiar and validated ADOS-2. However, the study highlights perceived limitations of the ADOS-2 and strengths of the BOSA, with recommendations made for future practice and research.

Oxygen saturation probe-related pressure injury prevention in children on an inpatient pediatric unit: a best practice implementation project.

OBJECTIVES: The aim of this project was to increase compliance with rotation and documentation of rotation of oxygen saturation probes to reduce medical-device-related pressure injuries in children on a pediatric inpatient unit. INTRODUCTION: There are a multitude of factors that place hospitalized children at an increased risk for medical-device-related pressure injuries. Evidence supports the rotation of medical devices, if appropriate, at least twice daily to minimize the risk of medical-device-related pressure injuries in hospitalized children. METHODS: The project used JBI's Practical Application of Clinical Evidence System and Getting Research into Practice audit tool for encouraging evidence-based practices. A baseline audit was conducted, followed by the implementation of targeted strategies. The project was completed with a follow-up audit to determine change in practice. RESULTS: The baseline audit revealed significant deficits in two of the seven audit criteria. Barriers to the rotation of oxygen saturation probes and the assessment of skin under oxygen saturation probes were identified by the project team and an electronic health record (EHR) documentation change was implemented. Follow-up audits were not conducted on the five criteria that showed high compliance at baseline. For the remaining two audit criteria, data revealed no improvement in one of the criteria (3% compliance at both baseline and follow-up audits) and an increase from 0% compliance to 43% compliance in the second criterion. CONCLUSION: Optimizing EHR documentation, specifically ease and efficiency of EHR documentation, has the potential to positively impact clinical practice.

Mobile injury prevention programs for children: a scoping review protocol.

OBJECTIVE: The objective of this review is to examine mobile injury prevention programs for children and their families. INTRODUCTION: Unintentional injuries are the leading cause of death worldwide for children aged one to 18years. Providing injury prevention education to children and their families is a necessary and critical element in health promotion. INCLUSION CRITERIA: This review will consider studies that include children from birth to 18years of age and their parents or guardians. The concept of this review is mobile or traveling injury prevention education programs for the specified population. Studies conducted in any geographic location or setting that report on how these programs are being utilized, who is providing the education, where education is being provided, who is funding the education, and outcome measures reported with mobile injury prevention programs will be included in the review. METHODS: This review will follow JBI's guidance for scoping reviews. The key databases to be searched include MEDLINE (PubMed), CINAHL (EBSCO), the Cochrane Library (Wiley), ERIC (EBSCO), Web of Science (Clarivate), and Embase (Elsevier). The search for unpublished studies will consist of OpenGrey ( www.opengrey.eu ) and ProQuest Dissertations and Theses Sciences and Engineering Collection (ProQuest). Studies conducted in English, in any year, will be included. Two independent reviewers will perform title and abstract screening, retrieval and review of full-text studies, and data extraction. The results will be presented in diagrammatic or tabular form that aligns with a narrative summary.

Latch On: A protocol for a multi-centre, randomised controlled trial of perinatal support to improve breastfeeding outcomes in women with a raised BMI.

INTRODUCTION: Breastfeeding is associated with improved maternal and child outcomes. Women with a higher body mass index (BMI), who comprise about 50% of the population, are at increased risk of poorer breastfeeding practices and are a population who would benefit from breastfeeding. METHODS: This protocol is for a multi-centre, randomised controlled trial of perinatal breastfeeding support among primiparous women with a BMI >25 kg/m2, using a previously-tested, multi-component intervention. The primary outcome is any breastfeeding at 3 months. The intervention will support mothers and their partners and spans from late pregnancy to six weeks postpartum. Intervention components include group antenatal breastfeeding education, individual face-to-face education in the immediate postnatal period, professional support to six weeks' postpartum and weekly phone calls in the immediate postpartum period from an International Board Certified Lactation Consultant (IBCLC). The intervention will target attitudes towards breastfeeding, breastfeeding self-efficacy, and subjective norms around infant feeding with the aim to normalise the behaviour. RESULTS: We anticipate that the intervention will be well-accepted and feasible to carry out within four maternity units in the East of Ireland. Furthermore, essential formative qualitative work has been conducted to inform the intervention design and to ensure that it is contextually appropriate. CONCLUSION: The proposed intervention will be invaluable to policy-makers in providing insights into what specific interventions are effective in improving breastfeeding rates for women with a raised BMI.

Screening for psychological distress using the Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS): Initial validation of structural validity in dialysis patients.

OBJECTIVE: To validate the factor structure of the Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS)- which is a composite measure of depression and anxiety using the Patient Health Questionnaire-9 and Generalised Anxiety Disorder Scale (GAD-7), in a sample of haemodialysis patients. METHOD: Screening data (n=182) used to select entry into a feasibility study of an online cognitive-behavioural therapy intervention for distress in dialysis patients were analysed here. Structural validity of the PHQ-ADS was evaluated using confirmatory factor analysis (CFA), assessing alternative models including a bi-factor model. In the bi-factor model all items from the PHQ-9 and GAD-7 (16-items in total) were loaded onto a general distress factor. Respective items of the PHQ-9 and GAD-7 were specified as subgroup factors. Omega-hierarchical was calculated to indicate the level of saturation of a multidimensional scale by a general factor. Construct validity was determined against the Brief Illness Perception Questionnaire. RESULTS: A bi-factor PHQ-ADS model had good fit to the data (chi-square=96.1, p=0.26, CFI=0.99; TLI=0.99; RMSEA=0.02). The general distress factor accounted for approximately 84% of the explained variance (omega-h=0.90). Distress scores were significantly higher in females compare with males. There was a significant association between distress and negative illness perceptions (r=0.58, p<0.01). CONCLUSIONS: The PHQ-ADS appears to have good structural validity in haemodialysis patients and is sufficiently unidimensional to warrant the use of a total distress score. A full psychometric analysis of the PHQ-ADS in a larger sample of dialysis patients is warranted.

Tailored online cognitive behavioural therapy with or without therapist support calls to target psychological distress in adults receiving haemodialysis: A feasibility randomised controlled trial.

BACKGROUND: Psychological distress is prevalent in haemodialysis (HD) patients yet access to psychotherapy remains limited. This study assessed the feasibility and acceptability of online cognitive-behavioural therapy (CBT) tailored for HD patients, with or without therapist support, for managing psychological distress. METHODS: This feasibility randomised controlled trial recruited patients from a UK HD centre. Following psychological distress screens, patients with mild-moderate psychological distress (Patient Health Questionnaire PHQ-9; score: 5-19 and/or Generalised Anxiety Disorder; GAD-7 score: 5-14) who met remaining inclusion criteria were approached for consent. Consenters were individually randomised (1:1) to online-CBT or online-CBT plus three therapist support calls. Outcomes included recruitment, retention, and adherence rates. Exploratory change analyses were performed for: psychological distress, quality of life (QoL), illness perceptions, and costs. The statistician was blinded to allocation. RESULTS: 182 (44%) out of 410 patients approached completed psychological distress screens. 26% found screening unacceptable; a further 30% found it unfeasible. Psychological distress was detected in 101 (55%) patients, 60 of these met remaining inclusion criteria. The primary reason for ineligibility was poor computer literacy (N=17, 53%). Twenty-five patients were randomised to the supported (N=18) or unsupported arm (N=7); 92% were retained at follow-up. No differences in psychological distress or cost-effectiveness were observed. No trial adverse events occurred. CONCLUSION: Online CBT appears feasible but only for computer literate patients who identify with the label psychological distress. A definitive trial using the current methods for psychological distress screening and online care delivery is unfeasible. ClinicalTrials.gov Identifier: NCT02352870.

Phenology of the Potato Psyllid, Bactericera cockerelli (Hemiptera: Triozidae), and "Candidatus Liberibacter solanacearum" in Commercial Potato Fields in Idaho.

Zebra chip disease (ZC) is an emerging disease of potato in which tubers are produced with striped necrotic patterns that make them unmarketable. ZC is associated with the bacterium "Candidatus Liberibacter solanacearum" (Lso), which is transmitted by the potato psyllid, Bactericera cockerelli (Sulc; Hemiptera: Triozidae). First found in Idaho during 2011, ZC now contributes to increased production costs each season via additional insecticide sprays. To clarify the extent and severity of the threat of ZC in Idaho, we sampled potato psyllids in commercial potato fields across the state over four growing seasons (2012-2015). All life stages of psyllids were sampled using a combination of methods (yellow sticky traps, vacuum samples, and leaf samples), and adult psyllids were tested for the presence of Lso by Polymerase Chain Reaction (PCR). Abundance of potato psyllids initially increased gradually over each growing season, then exhibited a sharp late-season rise and a sharp decline as most fields were being harvested. Abundance of psyllids was higher at warmer, lower elevation sites, but infestation onset did not differ between growing regions. Fewer psyllids were collected in vacuum samples than in sticky trap samples. Nymphs and eggs were found only late season and during years with high abundance of adults. Overall incidence of Lso was similar among all years but one. The results presented here clarify our understanding of the seasonal phenology of potato psyllids and Lso in Idaho potato fields and will aid in developing integrated management strategies against this important pest of potato.

Cognitive bias modification for social anxiety in adults who stutter: a feasibility study of a randomised controlled trial.

OBJECTIVE: To determine the feasibility and acceptability of a computerised treatment for social anxiety disorder for adults who stutter including identification of recruitment, retention and completion rates, large cost drivers and selection of most appropriate outcome measure(s) to inform the design of a future definitive trial. DESIGN: Two-group parallel design (treatment vs placebo), double-blinded feasibility study. PARTICIPANTS: 31 adults who stutter. INTERVENTION: Attention training via an online probe detection task in which the stimuli were images of faces displaying neutral and disgusted expressions. MAIN OUTCOME MEASURES: Psychological measures: Structured Clinical Interview Global Assessment of Functioning score; Liebowitz Social Anxiety Scale; Social Phobia and Anxiety Inventory; State-Trait Anxiety Inventory; Unhelpful Thoughts and Beliefs about Stuttering. Speech fluency: percent syllables stuttered. Economic evaluation: resource use questionnaire; EuroQol three-dimension questionnaire.Acceptability: Likert Scale questionnaire of experience of trial, acceptability of the intervention and randomisation procedure. RESULTS: Feasibility of recruitment strategy was demonstrated. Participant feedback indicated that the intervention and definitive trial, including randomisation, would be acceptable to adults who stutter. Of the 31 participants who were randomised, 25 provided data at all three data collection points. CONCLUSIONS: The feasibility study informed components of the intervention. Modifications to the design are needed before a definitive trial can be undertaken. TRIAL REGISTRATION NUMBER: I SRCTN55065978; Post-results.

Smoking and common mental disorders in patients with chronic conditions: An analysis of data collected via a web-based screening system.

OBJECTIVE: Smoking is the largest preventable cause of death and disability in the UK and remains pervasive in people with mental disorders and in general hospital patients. We aimed to quantify the prevalence of mental disorders and smoking, examining associations between mental disorders and smoking in patients with chronic physical conditions. METHOD: Data were collected via routine screening systems implemented across two London NHS Foundation Trusts. The prevalence of mental disorder, current smoking, nicotine dependence and wanting help with quitting smoking were quantified, and the relationships between mental disorder and smoking were examined, adjusting for age, gender and physical illness, with multiple regression models. RESULTS: A total of 7878 patients were screened; 23.2% screened positive for probable major depressive disorder, and 18.5% for probable generalised anxiety disorder. Overall, 31.4% and 29.2% of patients with probable major depressive disorder or generalised anxiety disorder respectively were current smokers. Probable major depression and generalised anxiety disorder were associated with 93% and 44% increased odds of being a current smoker respectively. Patients with depressive disorder also reported higher levels of nicotine dependence, and the presence of common mental disorder was not associated with odds of wanting help with quitting smoking. CONCLUSION: Common mental disorder in patients with chronic physical health conditions is a risk factor for markedly increased smoking prevalence and nicotine dependence. A general hospital encounter represents an opportunity to help patients who may benefit from such interventions.

Amyloid fibril formation by a domain of rat cell adhesion molecule.

Amyloid fibrils are protein aggregates implicated in several amyloidotic diseases. Cellular membranes with local decrease in pH and dielectric constant are associated with the amyloid formation. In this study, domain 1 of cell adhesion molecule CD2 (CD2-1) is used for studying amyloid fibril formation in a water/trifluoroethanol (TFE) mixture. CD2-1 is an all beta-sheet protein similar in topology to the amyloidogenic light chain variable domain, which deposits as amyloid in light chain amyloidosis at acidic pH. When incubated at pH 2.0 in the presence of 18% TFE, CD2-1 initiates the process to assemble into amyloid fibrils. It has been shown that TFE induces CD2-1 conformational change with a chemical transition (C(m)) of 18% (v/v). ANS (1-anilinonapthalene-8-sulfonic acid) binding was used to show that the hydrophobic surface becomes exposed under these solvent conditions. Our studies indicate that partial formation of a non-native conformation and the exposure of the hydrophobic interior could be the origins of oligomerization and fibril formation of CD2-1.
