Facilitating cardiopulmonary resuscitation training in high-risk areas of England: A study protocol.

Introduction: Bystanders' interventions improve chances of survival from out-of-hospital cardiac arrest (OHCA) before Emergency Medical Services arrive. Some areas in England are of concern. These high-risk areas have a higher incidence of cardiac arrest combined with lower-than-average bystander CPR rates and are characterised by higher proportions of minority ethnic group residents and deprivation.Collaborating with people from the Black African and Caribbean and South Asian minority communities in deprived areas of England, we aim to develop and evaluate the implementation of theoretically informed intervention(s) to address factors contributing to lower bystander intervention rates. Methods: The study is a collaborative realist enquiry, informed by the Theoretical Domains Framework and associated Behaviour Change Wheel. It consists of 1) a realist evidence synthesis to produce initial program theories developed from primary workshop data and published evidence. It will include identifying factors contributing to the issue and potential interventions to address them; 2) theoretically informed intervention development, using the initial program theories and behaviour change theory and 3) a realist mixed methods implementation evaluation with embedded feasibility.Public involvement (PPI) as study team and public advisory group members is key to this study.We will conduct realist evidence synthesis, qualitative and statistical analyses appropriate to the various methods used. Dissemination: We will develop a dissemination plan and materials targeted to members of the public in high-risk areas as well as academic outputs. We will hold an event for participating community groups and stakeholders to share findings and seek advice on next steps. Study registration: ISRCTN90350842. Registration date 28.03.2023.

Taiwanese Older Adults Prefer to Use Antibiotics and Intravenous Infusion at the End of Life based on a Cartoon Version of the Life Support Preferences Questionnaire.

Asians believe discussing death-related topics is inauspicious and may bring bad luck. It is critical to explore the end-of-life care preferences of the Asian elderly with less-threatening tools. The study examined older adults' preferences regarding end-of-life treatments by applying a cartoon version of the Life Support Preferences Questionnaire (LSPQ). A cross-sectional survey was conducted to understand older adults' preferences for end-of-life treatments. A total of 342 older adults participated in the study, comprising 268 elderly patients from a veterans hospital located in northern Taiwan and 74 elderly family members of the patients. Regardless of scenario, cardiopulmonary resuscitation (CPR) had the lowest score, indicating that older adults considered it a less desirable medical treatment. By contrast, antibiotics and intravenous infusions had the highest scores, indicating that older adults tended to prefer them. End-of-life care preferences were significantly different in genders. CPR and surgical preferences of older adults differed significantly with education level. Different demographic characteristics had different end-of-life treatment preferences, and future research may develop advance care planning programs for different attributes. This cartoon version of the LSPQ can help healthcare professionals to understand older adults' preferences for end-of-life care and warrants further empirical research.

Older Adults' Behavioral Intentions Toward Advance Care Planning Based on Theory of Reasoned Action.

This study aimed to explore the factors affecting the behavioral intentions of older adults toward advance care planning (ACP). A questionnaire survey was conducted at 2 medical wards and a senior activity center in northern Taiwan. Four hundred one participants were older adults aged over 65 years, comprising hospitalized patients, their caregivers, and members of a senior activity center. The regression model revealed that participant type (patient, caregiver, or community resident); financial support; discussion of ACP with family; and knowledge, attitudes, and subjective norms accounted for 46.3% of the variance in behavioral intentions. The behavioral intention of caregivers was higher than that of patients. The behavioral intention of participants who were financially dependent on the family was lower than that of pensioners. Regarding discussing ACP with family, older adults in the contemplation and preparation stages score higher on behavioral intention than those in the precontemplation stage. This study supports the theory of reasoned action. Older adults' ACP knowledge and attitudes need to be enhanced through education. Caregivers' behavioral intentions tend to perform ACP. Sharing their caring experiences may be a strategy for promoting ACP. Older adults' financial status affects their behavioral intentions. Therefore, financial planning should be performed early and should incorporate ACP.

"I Like People to Treat Me Normally": Barriers to Type 1 Diabetes Self-Management Among Adolescents.

Adolescents with type 1 diabetes face barriers that can have a negative influence on self-management behaviors. This study was an analysis of semi-structured interviews with adolescents, parents, and health care providers to better understand these barriers among adolescents in Jordan. Adolescents with type 1 diabetes reported individual-level barriers including feeling labeled, pitied, and stigmatized for having type 1 diabetes. They also discussed the system-level barrier of an education system that does not adapt to meet their needs. Individual- and system-level barriers are interrelated and could influence adolescents' decisions regarding whether to disclose their condition to others.

"It [Diabetes] is From God and I Need to Take Care of Myself": Type 1 Diabetes Self-Management Among Adolescents and Their Parents in Jordan.

BACKGROUND: Type 1 diabetes is the most common endocrine condition among adolescents. Diabetes self-management can be challenging during adolescence. OBJECTIVE: The objective of this study is to understand how adolescents and their parents manage type 1 diabetes in Jordan. METHODS: Constructivist grounded theory methodology principles were used to achieve the study aim. A total of 48 participants were recruited using purposive and theoretical sampling techniques, including adolescents and their parents. Data were collected (October 2016 - April 2017) using 38 semi-structured, audio-recorded interviews (one-to-one or joint interviews based on participants' preferences). Data were collected and analyzed concurrently using different levels of coding, constant comparative analysis, and memo writing. This study was approved by relevant ethics committees from the University of Manchester and Jordan University Hospital. RESULTS: The theme of living with diabetes is presented and discussed in this article. Culture emerged as the central theme; two aspects of culture are presented in this article: collectivism and cultural beliefs. CONCLUSION: This study identified that diabetes self-management could be influenced by the culture in which Jordanian adolescents live in as well as being shaped by their religious beliefs. These findings are potentially transferable to other Arab and non-Arab countries that share similar cultural aspects and religious beliefs.

Does Sleep Position Influence Sleep-Disordered Breathing in Infants With Cleft Palate: A Feasibility Study?

OBJECTIVE: Cleft palate (CP) can affect breathing, leading to sleep-disordered breathing (SDB). Sleep position can affect SDB, but the optimum sleep position for infants with CP is unknown. We aimed to determine the design of a pragmatic study to investigate the effect of the 2 routinely advised sleep positions in infants with CP on oxygen saturations. DESIGN: A multicentered observational cohort. SETTING: Four UK-based cleft centers, 2 advising supine- and 2 side-lying sleep positions for infants with CP. PARTICIPANTS: Infants with isolated CP born July 1, 2015, and December 31, 2016. Of 48 eligible infants, 30 consented (17 side-lying; 13 supine). INTERVENTIONS: Oxygen saturation (SpO2) and end-tidal carbon dioxide (ETCO2) home monitoring at age 1 and 3 months. Qualitative interviews of parents. OUTCOME MEASURES: Willingness to participate, recruitment, retention, and acceptability/success (>90 minutes recording) of SpO2 and ETCO2 monitoring. RESULTS: SpO2 recordings were obtained during 50 sleep sessions on 24 babies (13 side-lying) at 1 month (34 sessions >90 minutes) and 50 sessions on 19 babies (10 side-lying) at 3 months (27 sessions >90 minutes). The ETCO2 monitoring was only achieved in 12 sessions at 1 month and 6 at 3 months; only 1 was >90 minutes long. The ETCO2 monitoring was reported by the majority as unacceptable. Parents consistently reported the topic of sleep position in CP to be of importance. CONCLUSIONS: This study has demonstrated that it is feasible to perform domiciliary oxygen saturation studies in a research setting and has suggested that there may be a difference in the effects of sleep position that requires further investigation. We propose a study with randomization is indicated, comparing side-lying with supine-lying sleep position, representing an important step toward better understanding of SDB in infants with CP.

Study protocol for randomised clinical trial comparing the effectiveness of side-lying sleep positioning to back-lying at reducing oxygen desaturation resulting from obstructive sleep apnoea in infants with cleft palate (SLUMBRS2).

INTRODUCTION: The craniofacial abnormalities found in infants with cleft palate (CP) decrease their airway patency and increase their risk of obstructive sleep apnoea (OSA). We hypothesise that optimising sleep position in infants with CP may improve airway patency and offer a 'low-cost, high-impact' intervention to prevent the negative impacts of OSA. Because cleft centres give inconsistent advice about sleep position: some recommend back-lying and others side-lying, we will compare these in a randomised controlled trial. METHODS AND ANALYSIS: The aim is to determine the clinical effectiveness of side-lying as compared with back-lying sleep positioning in terms of reducing oxygen desaturation resulting from OSA in 244 infants aged 3-5 weeks of age, diagnosed with an isolated CP in/by UK cleft centres. Primary outcome is the 4% Oxygen Desaturation Index measured using pulse oximetry during sleep. RESEARCH PLAN: 1. Multicentre randomised controlled trial of side-lying compared with back-lying sleep positioning in reducing oxygen desaturation resulting from OSA in infants with CP at one month of age. 2. Internal pilot questionnaire-based study to support parents and clinicians regarding study participation, seeking to identify and address any barriers to recruitment. Monitoring data from the internal pilot will be used in the final analysis. 3. Co-development of new UK recommendations with Cleft Lip and Palate Association (CLAPA) regarding sleep position for infants with CP. ETHICS AND DISSEMINATION: The study protocol has received the favourable opinion of the West Midlands-South Birmingham Research Ethics Committee. Study results will be published on affiliated webpages and in peer-reviewed publications and conference contributions. TRIAL REGISTRATION NUMBER: NCT04478201.

Parental Experience of Sleep-Disordered Breathing in Infants With Cleft Palate: Comparing Parental and Clinical Priorities.

OBJECTIVE: To identify outcomes relating to sleep-disordered breathing (SDB) that are relevant to parents, during the early weeks of caring for infants with cleft palate (CP), and compare these with clinical outcomes identified in a systematic search of research literature. DESIGN: A qualitative study using telephone/face-to-face interviews with parents explored their understanding of breathing and respiratory effort in infants with CP. SETTING: Care provided by 3 specialist cleft centers in the United Kingdom, with study conducted in parents' homes. PARTICIPANTS: Criteria for participation were parents of infants with isolated CP aged 12 to 16 weeks. Thirty-one parents of infants with CP (over 12 weeks) were invited to participate in the interview. Interviews were completed with 27 parents; 4 parents could not be contacted after completing the sleep monitoring. RESULTS: Parents' description of infants' sleep suggests that breathing is not considered as a separate priority from their principal concerns of feeding and sleeping. They observe indicators of infants' breathing, but these are not perceived as signs of SDB. Parents' decision to use lateral or supine sleep positioning reflects their response to advice from specialists, observation of their infants' comfort, ease of breathing, and personal experience. Outcomes, identified in published research of SDB, coincide with parents' concerns but are expressed in medical language and fit into distinct domains of "snoring," "sleep," "gas exchange," and "apnea." CONCLUSIONS: Parents' description of sleeping and respiration in infants with CP reflect their everyday experience, offering insight into their understanding, priorities, and language used to describe respiration. Understanding parents' individual priorities and how these are expressed could be fundamental to selecting meaningful outcomes for future studies of airway interventions.

Development of an implementation intention-based intervention to change children's and parent-carers' behaviour.

BACKGROUND: Implementation intentions enable individuals to translate good intentions into action. Parents and children can find maintaining oral health difficult, as evidenced by the presence of tooth decay. This is a common condition in children in spite of being preventable through the use of regular tooth brushing, fluoride protection and avoiding sugar intake. Even when parents and children are positive about looking after the teeth, they can face challenges in maintaining consistent habits. The aim of this paper is to describe the design of a video animation to teach parents and children how to use implementation intentions to establish new habits to improve oral health, applied in this case, to parents and children with cleft lip and/or palate (CLP). METHODS: Evidence from a qualitative study of parents' and children's knowledge, beliefs and behaviour informed the design of an animation forming part of an intervention for children and parents using implementation intentions. The user views generated a set of guiding principles to determine the style and content of a teaching video, whilst an animation designer translated the key messages of implementation intention into images and characters appealing and meaningful to the target audience of children and parents. RESULTS: A team of researchers, an animation designer and a script writer designed a 2-min video as a teaching tool for children and parents. The team drafted and iteratively refined the content and visuals, with guidance from an advisory group and informal discussions with children in the target age group and their parents. Planning, consulting, designing and production of the animation spanned a total of 20 weeks. The video explains how to formulate 'if-then' plans using the voices of a boy and his mother in a conversation, with examples from oral health to illustrate how to enact intentions. It is available via digital media and designed to be delivered by dental care practitioners. The effectiveness of the intervention will be evaluated as part of a feasibility study. CONCLUSION: The current study describes the development of an intervention mediated through an animation tutorial that enables children and parents to devise 'if-then' plans to improve oral health as a collaborative endeavour between parents and children. The animation uses examples from oral health, but we believe there is scope for exploring application of the intervention to other areas of behaviour.

Herbst appliance with skeletal anchorage versus dental anchorage in adolescents with Class II malocclusion: study protocol for a randomised controlled trial.

BACKGROUND: The Herbst appliance is an orthodontic appliance that is used for the correction of class II malocclusion with skeletal discrepancies. Research has shown that this is effective. However, a potential harm is excessive protrusion of the lower front teeth. This is associated with gingival recession, loss of tooth support, and root resorption. This trial evaluates a method of reducing this problem. METHODS/DESIGN: The study is a single-center, randomised, assessor-blinded, superiority clinical trial with parallel 1:1 allocation. Male and female young people (10-14 years old) with prominent front teeth (class II, division 1) will be treated in one orthodontic clinic. Group 1 will be treated with the conventional Herbst appliance with dental anchorage and group 2 with the Herbst appliance with indirect skeletal anchorage for 12 months. The primary objective will be to compare the proclination of the lower incisors between the Herbst appliance with dental anchorage and skeletal anchorage. Secondary objectives will be to evaluate the changes occurring between the groups in the mandible, maxilla, lower and upper molars, and in gingival recession and root resorption at the end of the treatment. Additionally, the young patient's experience using the appliances will be assessed. The primary outcome measure will be the amount of lower incisor proclination at the end of treatment. This will be assessed by cone-beam computed tomography (CBCT) superimposition. Secondary outcome measures will be the changes in the mandible, maxilla, lower and upper molars at the end of treatment assessed by tomography superimposition and the young patient's experience using the appliances assessed by self-reported questionnaires and semi-structured interviews. The randomisation method will be blocked randomisation, using software to generate a randomised list. The allocation concealment will be done in opaque envelopes numbered from 1 to 40 containing the treatment modality. The randomisation will be implemented by the secretary of the Department of Orthodontics of Rio de Janeiro State University before the beginning of the study. The patients and the orthodontists who will treat the patients cannot be blinded, as they will know the type of appliance used. The technician who will take the CBCT image and the data analyst will be blinded to patients' group allocation. DISCUSSION: If this new intervention is effective, the findings can change orthodontic practice and may also be relevant to other forms of treatment in which appliances are fixed to the bones of the jaws. However, if the bone anchoring is not effective, the trial will provide much needed information on the use of this comparatively new development.

Experience of maintaining tooth brushing for children born with a cleft lip and/or palate.

BACKGROUND: Children with a Cleft Lip and/or Palate (CL/P) have been reported to have poorer oral health than those without the condition. The consequences for these children can be particularly problematic due to implications for future treatments. Tooth brushing is an important behaviour contributing to children's oral health, but is under researched in the CL/P population. The aim of the study is to explore the experience of maintaining tooth brushing among children in the United Kingdom (UK) with a CL/P and their parents. METHODS: Semi-structured interviews were carried out with twenty-two parents and sixteen children with a CL/P (5-11 years), recruited at a cleft centre in the UK. Thematic analysis was used for data analysis. RESULTS: Three key themes were drawn from the qualitative data: first, parents of children with a CL/P generally had strong motivation to look after their children's teeth but children's motivation was inconsistent. Second, parents were primary enablers of children's tooth brushing behaviour, often employing approaches adapted to their child's characteristics to encourage tooth brushing. Third, a range of obstacles were encountered by parents and children in maintaining regular tooth brushing behaviours. They reported obstacles such as issues related to CL/P, 'forgetting' and childhood illness. CONCLUSIONS: The paper suggests that parents of children with a CL/P need support to enact their intention to maintain regular tooth brushing and prioritise tooth brushing within the context of demanding and dynamic family life.

Parents' and children's knowledge of oral health: a qualitative study of children with cleft palate.

BACKGROUND: Children with cleft lip and/or palate (CLP) are prone to poorer oral health outcomes than their peers, with serious implications for treatment. Little is known of the knowledge and practice of children with CLP in caring for teeth and how these contribute to oral health. AIM: To investigate (i) parents' and children's knowledge of oral health, (ii) how knowledge is acquired, and (iii) how knowledge is implemented. DESIGN: A qualitative design was used to investigate knowledge, beliefs, and practices reported by parents and children, age 5-11 years with CLP. Data were collected from 22 parents and 16 children and analysed using thematic analysis. RESULTS: Four themes were derived as follows: (i) implicit knowledge: children express simple knowledge underpinned by basic rationales, (ii) situated knowledge: children gain skills as part of everyday childhood routines, (iii) maintaining good practice in oral health: parents take a lead role in motivating, monitoring, and maintaining children's toothbrushing, and (iv) learning opportunities: pivotal moments provide opportunities for children to extend their knowledge. CONCLUSION: Developers of oral health education interventions should take account of children's implicit knowledge and the transmission of beliefs between generations that influence toothbrushing behaviours. This could enhance interventions to support parents and children's practice.

Hepatitis C virus polyprotein vaccine formulations capable of inducing broad antibody and cellular immune responses.

Although approximately 3 % of the world's population is infected with Hepatitis C virus (HCV), there is no prophylactic vaccine available. This study reports the design, cloning and purification of a single polyprotein comprising the HCV core protein and non-structural proteins NS3, NS4a, NS4b, NS5a and NS5b. The immunogenicity of this polyprotein, which was formulated in alum, oil-in-water emulsion MF59 or poly(dl-lactide co-glycolide) in the presence or absence of CpG adjuvant, was then determined in a murine model for induction of B- and T-cell responses. The addition of adjuvants or a delivery system to the HCV polyprotein enhanced serum antibody and T-cell proliferative responses, as well as IFN-gamma responses, by CD4+ T cells. The antibody responses were mainly against the NS3 and NS5 components of the polyprotein and relatively poor responses were elicited against NS4 and the core components. IFN-gamma responses, however, were induced against all of the individual components of the polyprotein. These data suggest that the HCV polyprotein delivered with adjuvants induces broad B- and T-cell responses and could be a vaccine candidate against HCV.

Virus-induced inhibition of CD1d1-mediated antigen presentation: reciprocal regulation by p38 and ERK.

A critical component of the host's innate immune response involves lipid Ag presentation by CD1d molecules to NK T cells. In this study we used murine CD1d1-transfected L (L-CD1) cells to study the effect of viruses on CD1d-mediated Ag presentation to NKT cells and found that an infection with vesicular stomatitis and vaccinia (but not lymphocytic choriomeningitis) virus inhibited murine CD1d1-mediated Ag presentation. This was under the reciprocal control of the MAPKs, p38 and ERK, and was due to changes in the intracellular trafficking of CD1d1. The reciprocal regulation of CD1d1-mediated Ag presentation by MAPK suggests that the targeting of these pathways is a novel means of immune evasion by viruses.

Heparin inhibits dengue-2 virus infection of five human liver cell lines.

Liver is suggested to be the major target of dengue virus infection and plays an important role in the immunopathogenesis of dengue hemorrhagic fever. Previously, we reported that five human liver cell lines (HuH-7, HA22T, Hep3B, PLC, and Chang liver) with various degrees of differentiation and tumorigenicity showed different susceptibility for dengue virus infection. Here, we demonstrate that heparin, an analogue of heparan sulfate (HS), can compete with HS on cell membrane for virus binding and subsequently inhibits the replication of dengue-2 and Japanese encephalitis viruses in hepatoma and BHK-21 cells, respectively. It indicates that the binding of these viruses with HS is an important process for their invasion. Moreover, the inhibitory effect of heparin correlates with the infectivity of the virus in the cells. All together, our results suggest that HS is an important host component for dengue and Japanese encephalitis virus replication, which can be effectively blocked by heparin.
