The term "boundary-work" is used to refer to the constant effort to draw and re-draw the boundary of science; it has long been portrayed as constructed by the stakeholders of science to demarcate science from non-science to establish the authority of science. Twenty-nine semi-structured interviews were carried out with students from one university in England, originally to explore their views about genetically modified (GM) food. However, the distinctive repertoires adopted by students of natural science as opposed to humanities and social sciences were striking. As a result, the focus of this study shifted to examine the discourse students adopted to talk about a controversial scientific topic, using GM food as a case study. This paper shows that the boundary between scientific and non-scientific academic disciplines is heavily ingrained in university students' discourse and it is collectively constructed by both actors that are included in, and excluded from, the institution of science. The innate authority assigned to the institution of science is found to have deepened the gap between scientific and non-scientific disciplines. In this study, science disciplines were portrayed as coherent and consistent, following similar scientific methods and philosophy whereas humanities and social sciences disciplines were merely considered as "non-science" disciplines. Hence, this paper suggests the wide scope of science should be better recognised and acknowledged in the education system. Finally, this paper demonstrates that people's role in relation to the institution of science has an impact on their discourse about and, perhaps subsequently, their views towards, science and technology.

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.

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. [ABSTRACT FROM AUTHOR]

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.Trial Registration: ClinicalTrials.gov, protocol ID: NCT0241812 .

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. [ABSTRACT FROM AUTHOR]
