Developing text-messaging support for fathers after perinatal loss

BACKGROUND

Perinatal loss is a devastating occurrence for expecting parents. Although both parents are affected, research on fathers' grief has not resulted in effective support services for fathers.

AIM

To describe a multi-stage co-design process for developing text messaging support for fathers experiencing perinatal loss.

METHODS

Co-designed text messages were developed in collaboration with a perinatal bereavement organisation, mothers and fathers with lived experience of perinatal loss, and clinicians working with bereaved parents. Bereaved parents responded to a survey about bereaved fathers' information needs (stage 1). A qualitative descriptive data analysis created topics for the generation of text messages (stage 2). Parents with lived experience and clinicians evaluated the messages on importance and clinical fit (stage 3). Messages were revised (stage 4), followed by parent and clinician evaluation and final message revision (stage 5).

FINDINGS

There were 959 survey respondents; the majority agreed that support for fathers would have been useful; 539 provided comments. Qualitative analysis created twelve topics within three themes, leading to the generation of 64 text messages. Messages were evaluated by 27 lived experience parents and 19 clinicians as important (91.6%) and understandable (91.3%), and 92.5% of clinicians agreed the messages fitted clinical guidelines. Message revision resulted in 59 messages across three themes. The final evaluation by 12 parents and 14 clinicians led to a final revised set of 52 messages.

CONCLUSION

Text-based support for bereaved fathers can be developed in a co-design process to accord with clinical practice, from topics suggested parents with lived experience.

A Synthetic Cytotoxic T cell Platform for Rapidly Prototyping TCR Function

Current tools for functionally profiling T cell receptors with respect to cytotoxic potency and cross-reactivity are hampered by difficulties in establishing model systems to test these proteins in the contexts of different HLA alleles and against broad arrays of potential antigens. We have implemented and validated a granzyme-activatable sensor of T cell cytotoxicity in a novel universal prototyping platform which enables facile recombinant expression of any combination of TCR-, peptide-, and class I MHC-coding sequences and direct assessment of resultant responses. This system consists of an engineered cell platform based on the immortalized natural killer cell line, YT-Indy, and the MHC-null antigen-presenting cell line, K562. These cells were engineered using contemporary gene-editing techniques to furnish the YT-Indy/K562 pair with appropriate protein domains required for recombinant TCR expression and function in a non-T cell chassis, integrate a fluorescence-based target-centric early detection reporter of cytotoxic function, and deploy a set of protective genetic interventions designed to preserve antigen-presenting cells for subsequent capture and downstream characterization. Our data show successful reconstitution of the surface TCR complex in the YT-Indy cell line at biologically relevant levels. We also demonstrate successful induction and highly sensitive detection of antigen-specific response in multiple distinct model TCRs, with significant responses (p < 0.05 and Cohen's d >1.9) in all cases. Additionally, we monitored destruction of targets in co-culture and found that our survival-optimized system allowed for complete preservation after 24-hour exposure to cytotoxic effectors. With this bioplatform, we anticipate investigators will be empowered to rapidly express and characterize T cell receptor responses, generate new knowledge regarding the patterns of T cell receptor recognition, and optimize novel therapeutic T cell receptors for improved cytotoxic potential and reduced cross-reactivity to undesired antigenic targets.

Equipping fathers to support distressed mothers: What do mothers want fathers to know and do?

ISSUE ADDRESSED

Up to one in five new mothers experience depression or anxiety, and their partners are often the first line of social and practical support. However, many fathers are unprepared for their role as support person. The SMS4dads program (www.sms4dads.com) provides text-based support to new fathers but lacks specific messages addressing maternal mental distress.

METHODS

A mixed methods process engaged mothers with lived experience of perinatal mental distress to identify message content for co-designing texts in SMS4dads. Participants completed surveys derived from research literature and parenting websites using the theoretical framework of support domains: emotional or affectionate support, informational support, tangible support and positive social interaction. Mothers also indicated the most appropriate timing of support: at the point of identifying the distress (emerging), with ongoing symptoms (persistent) or during recovery (easing). Free text comments from mothers were linked to survey topics to provide examples of wording suitable for text messages to fathers.

RESULTS

Fifty-five mothers with lived experience completed the surveys. All support items were more often endorsed as helpful rather than not helpful by mothers. Emotional support was thought helpful in the early stages, tangible support was valued with ongoing symptoms and social interaction appreciated as symptoms eased.

CONCLUSIONS

Mothers experiencing perinatal depression and anxiety require a range of supportive actions by their partners, including household tasks and baby-care, encouragement, listening and managing relationships with family and friends. SO WHAT?: Information provided by distressed mothers can provide guidance to professionals when designing information for fathers/partners. Digital delivery of this co-designed information to fathers across urban and rural areas may enhance the competence of fathers working to support mothers experiencing mental distress in the perinatal period.

Developing a text message intervention for fathers with partners experiencing perinatal depression or anxiety

BACKGROUND

Support from fathers to their partners is important to reduce distress in mothers during the perinatal period when conditions such as depression and anxiety can be common. The SMS4dads digital platform delivers text messages to fathers but has not previously addressed specific messages to fathers with partners who are experiencing perinatal depression and/or anxiety (PNDA).

AIM

To develop messages, in collaboration with experienced parents and clinicians, that are suitable for fathers whose partner is experiencing PNDA.

METHODS

Messages designed to enhance the quality of partner support for mothers experiencing PNDA were drafted by the SMS4dads team based on suggestions from mothers with lived experience of PNDA. Mothers and fathers with lived experience and expert clinicians rated the messages for importance and understanding. Clinicians additionally rated clinical relevance. Open response comments from parents and clinicians were collated for each message. Re-drafted messages were screened again and checked for literacy level.

RESULTS

Forty-one draft messages received a total of 170 ratings from 24 parents and 164 ratings from 32 clinicians. Over three quarters of parents and clinicians agreed or strongly agreed that messages were understandable (parents 85.6%; clinicians 77.4%), important (parents 86.3%; clinicians 86.6%), and 85.5% of clinicians rated the messages as clinically relevant. Comments from clinicians (n = 99) and parents (n = 46) were reviewed and guided message development. Thirty re-drafted messages were screened and 16 edited based on a second round of ratings and comments from parents and clinicians.

CONCLUSION

Messages for fathers whose partners are experiencing depression and anxiety can be developed and evaluated in collaboration with lived experience of parents and clinicians.

Development of a Brief Coparenting Measure: The Coparenting Competence Scale

Coparenting competence (CC) is a concept that describes the sense of collective efficacy that parents experience in raising children. An advantage of CC is that it bridges a gap between family systems thinking and efficacy theory, where extant research and theory have focused on the self-efficacy of one or both parents. This study aimed to develop a self-reported measure of CC.

METHODOLOGY

Participants (n = 302), including cohabiting mothers (n = 240) and fathers (n = 62), completed an online survey (112 items) comprising demographic questions, the Coparenting Relationship Scale (CRS), the Parenting Sense of Competence Scale (PSOC), the Strengths and Difficulties Questionnaire (SDQ), and 36 items designed to explore perceptions of CC.

RESULTS

Factor analyses on 36-CC items identified 10 items that reliably formed a brief Coparenting Competence Scale (CCS; Alpha = 0.89). Analysis of convergent and divergent validity demonstrated that the CCS measures a unique construct that is linked to parenting self-efficacy, measured by PSOC (r = 0.47), and coparenting quality, assessed by the CRS (r = 0.63). There was a significant association between CCS and SDQ across age groups and an association stronger than that found for the CRS and SDQ in the current cohort.

CONCLUSIONS AND IMPLICATIONS

The study found support for the reliability and validity of the CCS. Coparenting competence, assessed by the CCS, was found to be distinct from factors previously used to represent coparenting quality in multivariate scales. The strength of associations between the CCS and SDQ suggests this new measure may have an important role in coparenting research.

The Solent Strait: Water quality trends within a heavily trafficked marine environment, 2000 to 2020

This study presents an important long-term historical analysis of water quality in an internationally crucial waterway (the Solent, Hampshire, UK), in the context of increasing adoption of open-loop Exhaust Gas Cleaning Systems by shipping. The pollutants studied were acidification (pH), zinc, and benzo [a] pyrene, alongside temperature. We compared baseline sites to locations likely to be impacted by pollution. The Solent's average water temperature is slightly increasing, with temperatures at wastewater sites significantly higher. Acidification suggests a complex story, with a highly significant small overall increase in pH during the study period but significantly different values at wastewater and port sites. Zn concentrations have significantly reduced but increased in enclosed waters such as marinas. BaP showed no long-term trend with values at marinas significantly and consistently higher. The findings provide valuable long-term background data and insights that can feed into the upcoming review of the European Union's Marine Strategy Framework Directive and ongoing discussions about the regulation of, and future monitoring and management strategies for coastal/marine waterways.

P11.45.B Improved overall survival following Stereotactic Radiosurgery for brain metastases - a single institution experience

Background

Brain metastases are increasingly common due to longer survival associated with advancements in treatment. Approximately 40% of cancer patients are diagnosed with brain metastases at some point during their disease. Stereotactic radiosurgery (SRS) avoids the neuro-cognitive toxicity associated with whole brain radiotherapy and has been increasingly offered as a treatment alternative for brain metastases. Combined with developments in systemic treatments, this approach has resulted in improved overall survival (OS). This study reviewed patients treated with single fraction SRS at our institution with a primary endpoint of overall survival.

Material and Methods

A retrospective review determined overall survival for 237 patients who received single fraction SRS for 451 brain metastases from solid tumours between 1st January 2017 and 31st December 2021. Primary tumour sites were classified as breast, kidney, colorectal, melanoma, lung or other. SPSS v.27 was used for Kaplan Meier OS determination. The median follow up was 10.3 months. Cox regression analysis assessed the association between Gross Tumour Volume (GTV) and OS.

Results

In this patient cohort, 60% (N=142) were female and 40% (N=95) were male, with a median age of 63 [32-85]. 63.7% (N = 151) had a solitary metastasis. Patients received a single fraction of 15, 17.5 or 20 Gy (prescribed to 80% isodose) dependent on the planning target volume (PTV) size and whether it was initial treatment or re-treatment. 71% of all patients were alive at 6 months with median OS of 12.0 months [10.6-13.4]. Primary tumour site significantly affected OS (Log rank, Chi squared 15.656, p0.008) with breast cancer patients (N=58) surviving longest with a median OS 16.0 months [13.6-18.4] followed by melanoma median OS 15.0 months [7.6-22.4], kidney cancer patients (N = 24) median OS 12.0 months [8.3-15.7] and lung patients (N=87) median OS 10.0 months [8.9-11.3]. The lowest median OS was for colorectal patients at 7.0 months [1.4-12.6]. However, considering the small sample size, N = 15, more data is needed to confirm the significance. The larger the GTV volume the lower the survival time (Chi squared 8.692, p 0.003).

Conclusion

71% of patients had an OS of 6.0 months or more with a median of 12.0 months. As expected, primary tumour site has a significant impact on OS, with breast cancer patients living longest. In addition, increasing GTV size is associated with significantly worse survival. Given the improved survival for these patients, the avoidance of neuro cognitive decline remains of paramount importance and outcomes for these patients need to be reported in future work.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study

BACKGROUND

Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications.

METHODS

We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC).

FINDINGS

In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]).

INTERPRETATION

In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required.

Video Folding: Increased Framerate for Semi-Repetitive Sequences

We introduce a technique to synthetically increase the framerate of semi-repetitive videos (i.e., videos of motion that repeats but not in an identical fashion) to aid in visualization. By reordering and combining frames from all repetitions, we produce a single non-repetitive sequence with much higher temporal resolution. Then, we use a novel frame warping technique based on a dense corrective flow to counteract differences between repetitions. The resulting video maintains smoothness of motion and additionally allows for seamless, infinite looping. We demonstrate the effectiveness of the proposed solution both quantitatively, by measuring the improvement over existing methods, and qualitatively, by performing a user evaluation and providing several examples in the article and accompanying video.

Assessing attention orienting in mice: a novel touchscreen adaptation of the Posner-style cueing task

Atypical attention orienting has been found to be impaired in many neuropsychological disorders, but the underlying neural mechanism remains unclear. Attention can be oriented exogenously (i.e., driven by salient stimuli) or endogenously (i.e., driven by one's goals or intentions). Genetic mouse models are useful tools to investigate the neurobiology of cognition, but a well-established assessment of attention orienting in mice is missing. This study aimed to adapt the Posner task, a widely used attention orienting task in humans, for use in mice using touchscreen technology and to test the effects of two attention-modulating drugs, methylphenidate (MPH) and atomoxetine (ATX), on the performance of mice during this task. In accordance with human performance, mice responded more quickly and more accurately to validly cued targets compared to invalidly cued targets, thus supporting mice as a valid animal model to study the neural mechanisms of attention orienting. This is the first evidence that mice can be trained to voluntarily maintain their nose-poke on a touchscreen and to complete attention orienting tasks using exogenous peripheral cues and endogenous symbolic cues. The results also showed no significant effects of MPH and ATX on attention orienting, although MPH improved overall response times in mice during the exogenous orienting task. In summary, the current study provides a critical translational task for assessing attention orienting in mice and to investigate the effects of attention-modulating drugs on attention orienting.

Effectiveness of family-based weight management interventions for children with overweight and obesity: an umbrella review

OBJECTIVES

The objective of the review was to synthesize the effectiveness and strategies used in family-based behavioral childhood obesity interventions in improving child weight-related outcomes.

INTRODUCTION

Family-based interventions are common practice in the treatment of childhood obesity. Research suggests that direct parental involvement can improve child weight-related outcomes. However, challenges remain in assessing the effects of family-based interventions on child weight and weight-related behavior due to the lack of quality programs and diversity of treatment strategies.

INCLUSION CRITERIA

The review included systematic reviews and/or meta-analyses of family-based behavioral interventions in children aged ≤18 who were classified as overweight and/or obese, and which reported child weight related outcomes, such as body mass index (BMI), body fat percentage and waist circumferences.

METHODS

Seven databases were searched from 1990 to May 2016 to identify English language publications. Reference lists of included reviews and relevant registers were also searched for additional reviews. All included systematic reviews were critically appraised by two reviewers independently. Data extracted included characteristics of included systematic reviews and weight-related outcomes reported. Data synthesis involved categorizing the interventions into seven categories and presented findings in narrative and tabular format. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach.

RESULTS

The umbrella review included 14 systematic reviews (low to moderate methodological quality), published between 2004 and 2015, including 47 independent trials ranging from one month to seven years follow-up conducted in more than 16 countries. The majority of reviews (93%) reported weight outcomes of children aged six to 13 years. All reviews except one indicated that family-based interventions were successful in improving child weight and/or weight-related behavior. Five reviews highlighted that parent-only interventions had similar (n = 4) or greater (n = 1) effectiveness compared to parent-child interventions. Effective interventions employed parent-targeted strategies, including nutrition and physical activity education sessions, positive parenting skills, role modelling and child behavior management to encourage positive healthy eating/exercise behaviors in children and/or whole family.

CONCLUSIONS

Family-based interventions targeting parents, alone or with their child, are effective for child weight management. Due to the lack of high quality evidence, especially in emerging parent-only interventions, further research is warranted. Health practitioners can work with parents as agents of change and focus on fostering positive parenting skills, such as monitoring, reinforcement, role modelling, and providing a nurturing environment, in order to support health behaviors in their children. Future research needs to explore whether parent-only interventions are more cost-effective compared to parent-child interventions, and to include larger populations, longer intervention duration and follow-up.

Accuracy of Parent-Reported Child Height and Weight and Calculated Body Mass Index Compared With Objectively Measured Anthropometrics: Secondary Analysis of a Randomized Controlled Trial

Background

Electronic health (eHealth) interventions for children often rely on parent-reported child anthropometric measures. However, limited studies have assessed parental accuracy in reporting child height and weight via Web-based approaches.

Objective

The objective of this study was to determine the accuracy of parent-reported child height and weight, as well as body mass index and weight category that we calculated from these data. We also aimed to explore whether parent report was influenced by age, sex, weight status, or exposure to participation in a 12-week brief Web-based family lifestyle intervention.

Methods

This study was a secondary analysis of data from a 12-week childhood obesity pilot randomized controlled trial in families with children aged 4 to 11 years in Australia. We asked parents to report demographic information, including child height and weight, using an online survey before their child’s height and weight were objectively measured by a trained research assistant at baseline and week 12. We analyzed data using the Lin concordance correlation coefficient (ρc, ranging from 0 [poor] to ±1 [perfect] concordance), Cohen kappa coefficient, and multivariable linear regression models.

Results

There were 42 families at baseline and 35 families (83%) at week 12. Overall, the accuracy of parent-reported child height was moderate (ρc=.94), accuracy of weight was substantial (ρc=.96), and accuracy of calculated body mass index was poor (ρc=.63). Parents underreported child height and weight, respectively, by 0.9 cm and 0.5 kg at baseline and by 0.2 cm and 1.6 kg after participating in a 12-week brief Web-based family lifestyle intervention. The overall interrater agreement of child body mass index category was moderate at baseline (κ=.59) and week 12 (κ=.54). The weight category calculated from 74% (n=31) and 70% (n=23) of parent-reported child height and weight was accurate at baseline and week 12, respectively. Parental age was significantly (95% CI –0.52 to –0.06; P=.01) associated with accuracy of reporting child height. Child age was significantly (95% CI –2.34 to –0.06; P=.04) associated with reporting of child weight.

Conclusions

Most Australian parents were reasonably accurate in reporting child height and weight among a group of children aged 4 to 11 years. The weight category of most of the children when calculated from parent-reported data was in agreement with the objectively measured data despite the body mass index calculated from parent-reported data having poor concordance at both time points. Online parent-reported child height and weight may be a valid method of collecting child anthropometric data ahead of participation in a Web-based program. Future studies with larger sample sizes and repeated measures over time in the context of eHealth research are warranted. Future studies should consider modeling the impact of calibration equations applied to parent-reported anthropometric data on study outcomes.

Fidelity and acceptability of a family-focused technology-based telehealth nutrition intervention for child weight management

INTRODUCTION

Previous reviews of family-based interventions for childhood obesity treatment found that studies were of low methodological quality with inadequate details reported, especially related to intervention fidelity. The evaluation of fidelity is crucial to inform interpretation of the intervention outcomes. This study aimed to summarise intervention fidelity, participants' acceptability and satisfaction with a 12-week family-focused technology-based child nutrition and weight management intervention.

METHODS

Families with children aged 4-11 years participated in a telehealth intervention with complementary components: website, Facebook group and text messages. Intervention fidelity was reported using National Institutes of Health Treatment Fidelity Framework. Delivery was measured using a dietitian-reported evaluation survey. Google Analytics and Bitly platform were used to objectively track data on frequency and pattern of intervention use. Participants' acceptability and satisfaction were measured using a process evaluation survey.

RESULTS

Telehealth consultations delivered by trained dietitians had good adherence (≥83%) to the structured content. Process evaluation results indicated that parents (n = 30; mean age 41 years, 97% were female, body mass index 30 kg/m²) found the intervention components easy to use/understand (87-100%), the programme had improved their family/child eating habits (93%), and they wanted to continue using telehealth and the website, as well as recommending it to other parents (90-91%).

DISCUSSION

In summary, a family-focused technology-based child nutrition and weight management intervention using telehealth, website, Facebook and SMS can be delivered by trained dietitians with good fidelity and attain high acceptability and satisfaction among families with primary-school-aged children in New South Wales, Australia.

Feasibility and efficacy of a web-based family telehealth nutrition intervention to improve child weight status and dietary intake: A pilot randomised controlled trial

INTRODUCTION

Innovative eHealth solutions that improve access to child weight management interventions are crucial to address the rising prevalence of childhood obesity globally. The study aimed to evaluate the feasibility and preliminary efficacy of a 12-week online telehealth nutrition intervention to improve child weight and dietary outcomes, and the impact of additional text messages (SMS) targeted to mothers and fathers.

METHODS

Families with children aged 4 to 11 were randomised across three groups: Telehealth, Telehealth+SMS, or Waitlist control. Telehealth and Telehealth+SMS groups received two telehealth consultations delivered by a dietitian, 12 weeks access to a nutrition website and a private Facebook group. The Telehealth+SMS group received additional SMS. Feasibility was assessed through recruitment, retention, and intervention utilisation. Efficacy was assessed through changes in measured child body mass index (BMI), waist circumference and diet.

RESULTS

Forty-four (96%) and 36 (78%) families attended initial and second telehealth consultations, respectively. Thirty-six families (78%) completed week 12 assessments. Child BMI and waist circumference changes from baseline to week 12 were not statistically different within or between groups. Children in Telehealth+SMS had significantly reduced percentage energy from energy-dense nutrient-poor food (95% CI -21.99 to -0.03%E; p = .038) and increased percentage energy from healthy core food (95% CI -0.21 to 21.89%E; p = .045) compared to Waitlist control.

DISCUSSION

A family-focused online telehealth nutrition intervention is feasible. While the modest sample size reduced power to detect between-group changes in weight status, some improvements in child dietary intakes were identified in those receiving telehealth and SMS.

Identical and Nonidentical Twins: Risk and Factors Involved in Development of Islet Autoimmunity and Type 1 Diabetes

OBJECTIVE

There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings.

RESEARCH DESIGN AND METHODS

Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years.

RESULTS

At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects.

CONCLUSIONS

Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Development of text messages targeting healthy eating for children in the context of parenting partnerships

AIM

There has been an increase in the use of text messaging to deliver and support health interventions. The aim was to develop a bank of text messages targeting healthy eating for children in the context of parenting partnerships that could be used in a family intervention.

METHODS

Text messages were developed using the Theoretical Domains Framework and Behaviour Change Wheel COM-B model by study investigators using a three-phase approach: (i) initial development of a message bank; (ii) messages were reviewed and evaluated by experts and parents on their clarity, usefulness, and relevance using a 5-point Likert scale and open text spaces for additional feedback and (iii) refinement of messages content and finalised the message bank.

RESULTS

Messages were reviewed for 'clarity', 'usefulness' and 'relevance' by 20 parents and 28 health experts, who were predominantly female (92%), parents of primary school age children (33%), of low to middle socioeconomic status (78%), with a mean age of 39 years (SD ± 9.87). From an initial set of 97 messages developed, 48 messages were retained through consultation. Messages were designed to complement the intervention, while engaging both parents.

CONCLUSIONS

The three-phase development created a set of text messages acceptable to experts and parents that aim to support improvement in child eating behaviours. The process provides a template and practical guide for researchers and health providers looking to apply a systematic approach to text messages development. Future research should investigate acceptability and impact of these messages as a component of family-based nutrition intervention.

Characteristics and complexity of chronic pain patients referred to a community-based multidisciplinary chronic pain clinic

BACKGROUND

Community-based care fills an important service gap for patients living with chronic pain. Better understanding of unmet patient needs in the community may inform improved policy and resource allocation.

AIMS

The aim of this study was to describe patients presenting to a community-based, multidisciplinary chronic pain clinic in Vancouver, British Columbia.

METHODS

This is a retrospective cross-sectional study of 935 unique consecutive patients who completed an intake questionnaire between January 2016 and March 2017. All data were patient reported.

RESULTS

Nine hundred thirty-five patient records were analyzed for descriptive characteristics. The mean age of the population was 49.5 (SD = 14.9) years; 70% were female. Approximately 50% of patients lived below the poverty line in Vancouver; 30% were not working due to disability, 51% had pain for more than 5 years, and 63% reported severe functional impairment.

CONCLUSIONS

Substantial unmet need is demonstrated in this patient population accessing a community-based chronic pain clinic. The population described is mainly of working age with significant functional impairment, reflecting a high level of need due to severity and duration of symptoms, poverty, and other characteristics described.

A Survey of Orthopaedic Conditions in Small Animal Veterinary Practice in Britain

A two-month survey of small animal orthopaedic conditions was conducted by members of British Veterinary Orthopaedic association. Clinicians from 42 clinics participated from a variety of practice including referral, primary care and teaching institutions. A total of 1627 cases were recorded. The case load was dominated by dogs with evidence that in UK cats are underrepresented in veterinary orthopaedic practice. Evidence of breed predisposition to orthopaedic disease in dogs was not detected. The importance of trauma in younger patients and degenerative diseases in older dogs was confirmed. A strong similarity between the case loads seen at primary care and referral practices was recorded. The results of this survey may be useful to those planning clinical orthopaedic teaching and research programmes.

Members of BVOA recorded and collated details of all orthopaedic cases seen during February and March 1994. The case load was dominated by dogs with evidence that cats are underrepresented in orthopaedic practice. There were striking similarities between the case loads of primary care and referral institutes. The findings of this survey may help those responsible for planning clinical orthopaedic teaching and research.

Text-Based Program Addressing the Mental Health of Soon-to-be and New Fathers (SMS4dads): Protocol for a Randomized Controlled Trial

Background

Recent estimates indicating that approximately 10% of fathers experience Paternal Perinatal Depression (PPND) and the increasing evidence of the impact of PPND on child development suggest that identifying and assisting distressed fathers is justified on public health grounds. However, addressing new fathers’ mental health needs requires overcoming men’s infrequent contact with perinatal health services and their reluctance to seek help. Text-based interventions delivering information and support have the potential to reach such groups in order to reduce the impact of paternal perinatal distress and to improve the wellbeing of their children. While programs utilising mobile phone technology have been developed for mothers, fathers have not been targeted. Since text messages can be delivered to individual mobile phones to be accessed at a time that is convenient, it may provide a novel channel for engaging with “hard-to-reach” fathers in a critical period of their parenting.

Objective

The study will test the efficacy of SMS4dads, a text messaging program designed specifically for fathers including embedded links to online information and regular invitations (Mood Tracker) to monitor their mood, in order to reduce self-reported depression, anxiety and stress over the perinatal period.

Methods

A total of 800 fathers-to-be or new fathers from within Australia will be recruited via the SMS4dads website and randomized to the intervention or control arm. The intervention arm will receive 14 texts per month addressing fathers’ physical and mental health, their relationship with their child, and coparenting with their partner. The control, SMS4health, delivers generic health promotion messages twice per month. Messages are timed according to the babies’ expected or actual date of birth and fathers can enroll from 16 weeks into the pregnancy until their infant is 12 weeks of age. Participants complete questionnaires assessing depression, anxiety, stress, and alcohol at baseline and 24 weeks postenrolment. Measures of coparenting and parenting confidence are also completed at baseline and 24 weeks for postbirth enrolments.

Results

Supporting men through their transition to fatherhood with messages delivered to their smartphones: a feasibility study of SMS4dads

Background

The transition to parenthood can be a challenging time, in which both mothers and fathers experience increased risk of distress and depression. Mothers are more likely than fathers to engage with services and have their mental health monitored and attended to during the perinatal period. The present study aimed to explore whether smartphone technology could be used to address fathers’ needs across their transition to fatherhood.

Methods

A corpus of messages, including linked information and mood tracking software, was designed to support and enhance paternal relationships with their babies, their partners and themselves across the perinatal period. Messages were sent to project participants (N = 520) from 12-weeks’ gestation to 24-weeks after birth.

Results

Of those fathers enrolled (N = 520), 21.5% scored >13 on K6 and completion rate (85%) was similar between these and other fathers. Most fathers (63.1%) clicked at least one link and responses were received for 20.5% of mood tracker questions. The probability of reporting worse mood scores decreased over time. Fathers completing post study surveys (N = 101) reported that messages helped them in their experience of becoming a new dad (92.8%), as well as helping them develop a strong relationship with their new child (54.9%), and in their relationship with their partner (79%).

Conclusions

The present study has demonstrated that it is both feasible and acceptable to support new fathers with SMS4dads, a relationship-focused messaging system designed to be delivered to smartphones across fathers’ transition to parenthood.

A two phased study on health care professionals' perceptions of single or multi-use of intermittent catheters

AIMS

This two phase study aimed to explore health care professionals' teaching and prescribing practice related to intermittent catheterisation and to identify their perceptions about the possible implementation of a mixed (single and multi-use) package for intermittent catheterization.

INTRODUCTION

Single-use intermittent catheters are the norm in the UK although multi-use is common in some other countries. A recent Cochrane review found no difference in complications, including urinary tract infection rates, between those using single or multi-use catheters. A flexible option of both multi-use and single use intermittent catheters could provide users with more flexible choices in self-care. However, understanding health care professionals' perspectives is one of the keys to developing a multi-use intervention.

DESIGN

A qualitative research framework using in-depth interviews to inform an on line survey.

METHOD

In-depth interviews were conducted with health care professionals based in the UK who prescribe catheters, teach intermittent catheterisation or manage an intermittent catheterisation service. The interviewees were selected to represent a range of clinical areas, experience and professions - continence advisors, urology, multiple sclerosis (MS) and spinal cord injury specialist nurses, and General Practitioners. Following framework analysis the themes and factors identified were used to develop an on-line survey which was disseminated through health care professional networks whose members saw patients who use intermittent catheters.

RESULTS

Nineteen health care professionals participated in the telephone interviews; 206 completed the survey. A wide range of professionals in terms of experience and specialty afforded rich information regarding the contextual issues around the teaching and prescribing of intermittent catheters. The primary finding was that health care professionals were concerned about 'minimising health risk' and maximising 'normalcy' for those using intermittent self-catheterisation. Health care professionals who worked in the acute setting or had no experience of re-use were most resistant to the re-use of catheters. Professionals requested evidence that a multi-use package would not increase the risk of developing a urinary tract infection or increase the burden of use to a patient before a mixed package would be considered.

CONCLUSIONS

For multi-use to be acceptable, evidence based guidelines must be available for healthcare professionals and cleaning methods must be acceptable and safe for intermittent catheter users. Further evidence may be required to establish that a mixed catheter package is equivalent to single use only, particularly for outcomes such as urinary tract infection, urethral injury and quality of life.

RELEVANCE TO CLINICAL PRACTICE

This paper highlights that if multi-use catheters are to be successfully introduced into clinical practice, the ease of use, safety and effectiveness of the cleaning technique will need to be convincingly demonstrated by a range of well-defined users.

Parent, partner, co-parent or partnership? The need for clarity as family systems thinking takes hold in the quest to motivate behavioural change

Research is increasingly pointing to the importance of extending the focus of childhood obesity intervention to include fathers, fathering figures, and other members of a child's primary parenting network. Advances in communication technology are now making it possible to achieve this aim, within current resources, using modalities such text messaging, web-based resources and apps that extend intervention to parents not in attendance at face to face interactions. However, published research is often unclear as to which parent/s they targeted or engaged with, whether interventions planned to influence behaviours and capabilities across family systems, and how this can be achieved. As childhood obesity research employing information technology to engage with family systems takes hold it is becoming important for researchers clearly describe who they engage with, what they hope to achieve with them, and the pathways of influence that they aim to activate. This paper integrates extant knowledge on family systems thinking, parenting efficacy, co-parenting, and family intervention with the way parents are represented and reported in childhood obesity research. The paper concludes with recommendations on terminology that can be used to describe parents and parenting figures in future studies.

Antibiotic Stewardship for Non-Infectious Disease Physicians: Focusing on When to Withhold, Modify and Discontinue Antibiotics

The multiple drug resistant organism (MDRO) and Clostridium difficile infection (CDI) epidemics are progressing relentlessly. Antibiotic stewardship (ABS) has evolved to confront these scourges. The Joint Commission has formulated a standard for its implementation and this should promote its use where others have failed. However, precisely how to intervene needs definition. Healthcare workers need practicable guidelines. The article discusses clinical scenarios where antibiotics should be withheld (Table 1), how they should be modified (Table 2) and when they should be discontinued (Table 3), three focal points of ABS.

Patient and provider perspectives on home telecare: Preliminary results from a randomized controlled trial

A randomized controlled trial of home telecare for the management of acute exacerbations of chronic obstructive pulmonary disease has been undertaken in the north-west of England. A videophone was used that communicates via the ordinary telephone network. The intervention period for each participant was two weeks. Participants in the telecare arm of the trial were asked to complete logbooks to record their experiences of each telecare encounter. A simple, self-completed, 10–item questionnaire was used that consisted of a Likert scale, ranging from 1 (totally disagree) to 5 (totally agree). Fourteen nurses completed 150 logbooks and 22 patients completed 145 logbooks. These results demonstrate significant differences in perception between patients and their health-care providers with regard to telecare encounters across all the domains addressed. Participating patients consistently demonstrated more positive views of the telecare encounters than their health-care providers.

Factors affecting the adoption of telehealthcare in the United Kingdom: the policy context and the problem of evidence

The adoption of telehealthcare in the United Kingdom has been slow and fragmented. This paper presents a structural explanation for this by contrasting contending themes in recent UK health policy. It is argued that the conflict between trends towards modernizationand demands for evidence-based practicehave made it difficult for a major policy agency to emerge that can sponsor service development, and so proponents of telehealthcare have been forced to situate their work within the domain of R&D. This has led to a fragmented field of practice characterized by short-term and small-scale projects.

Evaluation of new technologies in health-care systems: what’s the context?

Evaluation is an essential component of the introduction of new technologies, treatment modalities and models of service delivery across the health-care sector. Such work attracts significant levels of public funding, but little attention has been paid to understanding evaluation as more than a set of applied methodological activities. This paper sets out an agenda for a more complex and richer understanding of evaluation as a set of professional and organizational dynamics.

Abstract PR12: Discovery and preclinical evaluation of cEt-modified KRAS antisense oligonucleotide inhibitors

KRAS is one of the most frequently mutated genes in cancer and its activation is thought to underlie the pathogenesis of up to 30% of all human tumors. However, to date KRAS has proven difficult to target with traditional pharmacologic approaches. Antisense technology is particularly attractive for such difficult drug targets as antisense oligonucleotide (ASO) inhibitors can be designed based on a targets RNA sequence alone.

cEt ASOs have been recently described and demonstrated to have significantly increased potency over previous generation ASO chemistries. Moreover, STAT3Rx/AZD9150, a cEt modified ASO targeting STAT3 mRNA was recently shown to produce robust STAT3 depletion in a broad range of xenograft models (AACR 2013) and importantly has also demonstrated promising single-agent antitumor activity in patients with advanced treatment-refractory cancers in phase I studies (ASCO 2013, EORTC 2014).

Here, we describe the preclinical evaluation of potent and selective cEt ASOs targeted to human or mouse KRAS mRNA. A human-specific KRAS cEt ASO which potently and selectively down-regulated KRAS demonstrated anti-proliferative effects and the expected down-stream pathway inhibition in a panel of KRAS mutant NSCLC, CRC and PDAC cells. The KRAS ASO was differentiated from MAPK pathway inhibitors selectively inhibiting the proliferation of KRAS mutant not KRAS wild type cells and not causing feedback reactivation of the MAPK or PI3K pathways. Systemic delivery of the KRAS ASO to mice bearing KRAS mutant NSCLC or CRC xenografts resulted in significant inhibition of KRAS tumour expression and antitumor activity. Importantly, the KRAS ASO also showed significant target knockdown and antitumor effects in KRAS mutant NSCLC patient-derived xenografts (PDX).

Finally, potent and selective murine-specific KRAS ASO produced robust target knockdown in a broad set of tissues without detectable tolerability signals associated with ASO-mediated systemic KRAS inhibition.

Taken together these data suggest that KRAS ASOs are an attractive therapeutic approach to target KRAS for the treatment of human cancers.

The DEXMART hand: Mechatronic design and experimental evaluation of synergy-based control for human-like grasping

This paper summarizes recent activities carried out for the development of an innovative anthropomorphic robotic hand called the DEXMART Hand. The main goal of this research is to face the problems that affect current robotic hands by introducing suitable design solutions aimed at achieving simplification and cost reduction while possibly enhancing robustness and performance. While certain aspects of the DEXMART Hand development have been presented in previous papers, this paper is the first to give a comprehensive description of the final hand version and its use to replicate human-like grasping. In this paper, particular emphasis is placed on the kinematics of the fingers and of the thumb, the wrist architecture, the dimensioning of the actuation system, and the final implementation of the position, force and tactile sensors. The paper focuses also on how these solutions have been integrated into the mechanical structure of this innovative robotic hand to enable precise force and displacement control of the whole system.

Another important aspect is the lack of suitable control tools that severely limits the development of robotic hand applications. To address this issue, a new method for the observation of human hand behavior during interaction with common day-to-day objects by means of a 3D computer vision system is presented in this work together with a strategy for mapping human hand postures to the robotic hand. A simple control strategy based on postural synergies has been used to reduce the complexity of the grasp planning problem. As a preliminary evaluation of the DEXMART Hand’s capabilities, this approach has been adopted in this paper to simplify and speed up the transfer of human actions to the robotic hand, showing its effectiveness in reproducing human-like grasping.
