Recommendations for delivering oral health advice: a qualitative supplementary analysis of dental teams, parents' and children's experiences

BACKGROUND

Tooth decay has a significant impact on children, their families and wider society. The dental consultation provides an opportunity to prevent tooth decay by engaging in an effective oral health conversation with parents and children. However, there is limited literature which explores how these oral health conversations are delivered, received, and understood.

AIM

To explore the common facilitators of delivering oral health advice from dental teams, parents' and children's experiences, to identify and inform practical recommendations for clinical practice.

METHOD

The current paper used a qualitative supplementary analysis to reanalyse data of existing published studies by applying a different research question. Qualitative focus groups were undertaken following a semi-structured interview guide with 27 dental team members (dentists, dental nurses, practice managers and receptionists), 37 parents and 120 children (aged 7-10 years old) in the northern region of England. Thematic analysis informed the identification of themes and aggregation of findings.

RESULTS

Three overarching themes were developed: (1) An engaging and personalised dental visit for parents and children; (2) Dental teams, parents and children working collaboratively to improve oral health habits; and (3) Recommending appropriate oral health products. Many parents and children had little recollection of any preventive oral health conversations when visiting the dentist. Practical solutions were identified by different stakeholders to facilitate three-way, personalised, non-judgemental and supportive oral health conversations. Adopting these innovative approaches will help to enable parents and their children to adopt and maintain appropriate oral health behaviours.

CONCLUSION

Understanding the context and triangulating the experiences of stakeholders involved in preventive oral health conversations for young children is an essential step in co-designing a complex oral health intervention. This study has provided recommendations for dental practices and wider paediatric health care services. Furthermore, the findings have informed the design of a complex oral health intervention called "Strong Teeth".

Organizational Barriers to Oral Health Conversations Between Health Visitors and Parents of Children Aged 9-12 Months Old

Background: Dental caries is the most prevalent preventable childhood disease and a major public health priority. Local authorities in England have a statutory responsibility to improve child health, including oral health, through the “Healthy Child Programme.” The “Healthy Child Programme,” which includes the provision of oral health advice is delivered by health visitors to parents of young children. To date, research has mainly concentrated on individual interactions between health visitors and parents, with less attention given to the broader context in which these oral health conversations between health visitor and parents take place.

Objective: Our study explored the organizational factors that obstruct health visitors from engaging in meaningful conversations with parents about young children's oral health.

Methods: Qualitative interviews and focus groups were held with health visiting teams (n = 18) conducting home visits with parents of 9–12-month olds in a deprived, urban area in England.

Results: The study revealed the wide variation in what and how oral health advice is delivered to parents at home visits. Several barriers were identified and grouped into four key themes: (1) Priority of topics discussed in the home visits; (2) Finance cuts and limited resources; (3) Oral health knowledge and skills; and (4) Collaborative working with other professionals. It was evident that organizational factors in current public health policy and service provision play an important role in shaping oral health practices and opportunities for behavior change.

Conclusion: Organizational practices and procedures play an important role in creating interaction patterns between health visiting teams and parents of young children. They often limit effective engagement with and positive change in oral health. For future oral health interventions to be effective, awareness of these barriers is essential alongside them being founded on evidence-based advice and underpinned by appropriate theory.

Assessment of structural chromosomal instability phenotypes as biomarkers of carboplatin response in triple negative breast cancer: the TNT trial

BACKGROUND

In the TNT trial of triple negative breast cancer (NCT00532727), germline BRCA1/2 mutations were present in 28% of carboplatin responders. We assessed quantitative measures of structural chromosomal instability (CIN) to identify a wider patient subgroup within TNT with preferential benefit from carboplatin over docetaxel.

PATIENTS AND METHODS

Copy number aberrations (CNAs) were established from 135 formalin-fixed paraffin-embedded primary carcinomas using Illumina OmniExpress SNP-arrays. Seven published [allelic imbalanced CNA (AiCNA); allelic balanced CNA (AbCNA); copy number neutral loss of heterozygosity (CnLOH); number of telomeric allelic imbalances (NtAI); BRCA1-like status; percentage of genome altered (PGA); homologous recombination deficiency (HRD) scores] and two novel [Shannon diversity index (SI); high-level amplifications (HLAMP)] CIN-measurements were derived. HLAMP was defined based on the presence of at least one of the top 5% amplified cytobands located on 1q, 8q and 10p. Continuous CIN-measurements were divided into tertiles. All nine CIN-measurements were used to analyse objective response rate (ORR) and progression-free survival (PFS).

RESULTS

Patients with tumours without HLAMP had a numerically higher ORR and significantly longer PFS in the carboplatin (C) than in the docetaxel (D) arm [56% (C) versus 29% (D), PHLAMP,quiet = 0.085; PFS 6.1 months (C) versus 4.1 months (D), Pinteraction/HLAMP = 0.047]. In the carboplatin arm, patients with tumours showing intermediate telomeric NtAI and AiCNA had higher ORR [54% (C) versus 20% (D), PNtAI,intermediate = 0.03; 62% (C) versus 33% (D), PAiCNA,intermediate = 0.076]. Patients with high AiCNA and PGA had shorter PFS in the carboplatin arm [3.4 months (high) versus 5.7 months (low/intermediate); and 3.8 months (high) versus 5.6 months (low/intermediate), respectively; Pinteraction/AiCNA = 0.027, Padj.interaction/AiCNA = 0.125 and Pinteraction/PGA = 0.053, Padj.interaction/PGA = 0.176], whilst no difference was observed in the docetaxel arm.

CONCLUSIONS

Patients with tumours lacking HLAMP and demonstrating intermediate CIN-measurements formed a subgroup benefitting from carboplatin relative to docetaxel treatment within the TNT trial. This suggests a complex and paradoxical relationship between the extent of genomic instability in primary tumours and treatment response in the metastatic setting.

Management of nystagmus in children: a review of the literature and current practice in UK specialist services

Nystagmus is an eye movement disorder characterised by abnormal, involuntary rhythmic oscillations of one or both eyes, initiated by a slow phase. It is not uncommon in the UK and regularly seen in paediatric ophthalmology and adult general/strabismus clinics. In some cases, it occurs in isolation, and in others, it occurs as part of a multisystem disorder, severe visual impairment or neurological disorder. Similarly, in some cases, visual acuity can be normal and in others can be severely degraded. Furthermore, the impact on vision goes well beyond static acuity alone, is rarely measured and may vary on a minute-to-minute, day-to-day or month-to-month basis. For these reasons, management of children with nystagmus in the UK is varied, and patients report hugely different experiences and investigations. In this review, we hope to shine a light on the current management of children with nystagmus across five specialist centres in the UK in order to present, for the first time, a consensus on investigation and clinical management.

"I prefer not to have a child than have a HIV-positive child": a Mixed Methods Study of Fertility Behaviour of Men Living with HIV in Northern Nigeria

BACKGROUND

In the era of HIV treatment as prevention, little research has focused on the fertility behaviour of men living with HIV. This study examines the predictors and motivators of fertility among men living with HIV and on antiretroviral treatment in Kano, Nigeria.

METHOD

Using mixed methods, structured questionnaires were administered to a clinic-based sample of men living with HIV (n = 270) and HIV-negative/untested controls (n = 270), followed by in-depth interviews with a sub-group of 22 HIV-positive participants. Logistic regression and the framework approach were used to analyse the data.

RESULTS

Compared to HIV-negative/untested controls, lower proportions of men living with HIV desired more children (79.3%, n = 214 vs. 91.1%, n = 246, p < 0.05) and intended to bear children within 3 years (57.0%, n = 154 vs. 67.0%, n = 181) (p < 0.05). Marital status (ever married vs. single) predicted fertility intention among men living with HIV (adjusted odds ratio, AOR = 4.70, 95% confidence interval CI, 1.75-13.64) and HIV-negative/untested controls (AOR = 4.23, 95% CI, 1.37-16.45). Men considered self and partner health status, HIV transmission risks, poverty, the effectiveness of interventions, child survival and religion when making fertility decisions.

CONCLUSION

Fertility desires remain high post-HIV diagnosis. HIV services should include integrated reproductive health programs that address the fertility desires of clients and include considerations for fertility services.

Age influences the thermal suitability of Plasmodium falciparum transmission in the Asian malaria vector Anopheles stephensi

Models predicting disease transmission are vital tools for long-term planning of malaria reduction efforts, particularly for mitigating impacts of climate change. We compared temperature-dependent malaria transmission models when mosquito life-history traits were estimated from a truncated portion of the lifespan (a common practice) versus traits measured across the full lifespan. We conducted an experiment on adult female Anopheles stephensi, the Asian urban malaria mosquito, to generate daily per capita values for mortality, egg production and biting rate at six constant temperatures. Both temperature and age significantly affected trait values. Further, we found quantitative and qualitative differences between temperature-trait relationships estimated from truncated data versus observed lifetime values. Incorporating these temperature-trait relationships into an expression governing the thermal suitability of transmission, relative R₀(T), resulted in minor differences in the breadth of suitable temperatures for Plasmodium falciparum transmission between the two models constructed from only An. stephensi trait data. However, we found a substantial increase in thermal niche breadth compared with a previously published model consisting of trait data from multiple Anopheles mosquito species. Overall, this work highlights the importance of considering how mosquito trait values vary with mosquito age and mosquito species when generating temperature-based suitability predictions of transmission.

Assessing the perceived impact of post Minamata amalgam phase down on oral health inequalities: a mixed-methods investigation

Background

Data from countries that have implemented a complete phase out of dental amalgam following the Minamata agreement suggest increased costs and time related to the placement of alternatives with consumers absorbing the additional costs. This aim of this study was to investigate the impact of a complete phase out of dental amalgam on oral health inequalities in particular for countries dependent on state run oral health services.

Methods

A mixed methods component design quantitative and qualitative study in the United Kingdom. The quantitative study involved acquisition and analysis of datasets from NHS Scotland to compare trends in placement of dental amalgam and a survey of GDPs in Yorkshire, UK. The qualitative study involved analysis of the free text of the survey and a supplementary secondary analysis of semi-structured interviews and focus groups with GDPs (private and NHS), dental school teaching leads and NHS dental commissioners to understand the impact of amalgam phase down on oral health inequalities.

Results

Time-trends for amalgam placement showed that there was a significant (p < 0.05) reduction in amalgam use compared with composites and glass ionomers. However dental amalgam still represented a large proportion (42%) of the restorations (circa 1.8 million) placed in the 2016–2017 financial year.

Survey respondents suggest that direct impacts of a phase down were related to increased costs and time to place alternative restorations and reduced quality of care. This in turn would lead to increased tooth extractions, reduced access to care and privatisation of dental services with the greatest impact on deprived populations.

Conclusion

Amalgam is still a widely placed material in state run oral health services. The complete phase down of dental amalgam poses a threat to such services and threatens to widen oral health inequalities. Our data suggest that a complete phase out is not currently feasible unless appropriate measures are in place to ensure cheaper, long-lasting and easy to use alternatives are available and can be readily adopted by primary care oral health providers.

"Strong Teeth"-a study protocol for an early-phase feasibility trial of a complex oral health intervention delivered by dental teams to parents of young children

Background

Dental attendance provides an important opportunity for dental teams to explore with parents the oral health behaviours they undertake for their young children (0–5 years old). For these discussions to be effective, dental professionals need to be skilled in behaviour change conversations. The current evidence suggests that dental teams need further support, training and resources in this area. Therefore, the University of Leeds and Oral-B (Procter & Gamble Company) have worked with the local community and dental professionals to co-develop “Strong Teeth” (an oral health intervention), which is delivered in a general dental practice setting by the whole dental team. The protocol for this early phase study will explore the feasibility and acceptability of the Strong Teeth intervention to parents and the dental team, as well as explore short-term changes in oral health behaviour.

Methods

Forty parents (20 of children aged 0–2 years old, and 20 of children aged 3–5 years old) who are about to attend the dentist for their child’s regular dental check-up will be recruited to the study. Parents and children will be recruited from 4 to 8 different dental practices. In the home setting, consent and baseline oral health behaviour data will be collected. The researchers will ask parents questions about their child’s oral health behaviours, including toothbrushing and diet. Three different proxy objective measures of toothbrushing will be collected and compared with self-report measures of parental supervised toothbrushing (PSB).

Discussion

The parent and child will then attend their dental visit and receive the Strong Teeth intervention, delivered by the dental team. This intervention should take 5–15 min to be delivered, in addition to the routine dental check-up. Furthermore, children aged 0–2 years old will receive an Oral-B manual children’s toothbrush, and children aged 3–5 years old will receive an Oral-B electric rechargeable children’s toothbrush. At 2 weeks and 2–3 months following the Strong Teeth intervention, further self-report and objective measures will be collected in the parent/child’s home. This data will be supplemented with purposively sampled qualitative interviews with parents (approximately 3 months following the intervention) and dental team members (following delivery of the intervention).

Ultrasound-activated microbubbles as a novel intracellular drug delivery system for urinary tract infection

The development of new modalities for high-efficiency intracellular drug delivery is a priority for a number of disease areas. One such area is urinary tract infection (UTI), which is one of the most common infectious diseases globally and which imposes an immense economic and healthcare burden. Common uropathogenic bacteria have been shown to invade the urothelial wall during acute UTI, forming latent intracellular reservoirs that can evade antimicrobials and the immune response. This behaviour likely facilitates the high recurrence rates after oral antibiotic treatments, which are not able to penetrate the bladder wall and accumulate to an effective concentration. Meanwhile, oral antibiotics may also exacerbate antimicrobial resistance and cause systemic side effects. Using a human urothelial organoid model, we tested the ability of novel ultrasound-activated lipid microbubbles to deliver drugs into the cytoplasm of apical cells. The gas-filled lipid microbubbles were decorated with liposomes containing the non-cell-permeant antibiotic gentamicin and a fluorescent marker. The microbubble suspension was added to buffer at the apical surface of the bladder model before being exposed to ultrasound (1.1 MHz, 2.5 Mpa, 5500 cycles at 20 ms pulse duration) for 20 s. Our results show that ultrasound-activated intracellular delivery using microbubbles was over 16 times greater than the control group and twice that achieved by liposomes that were not associated with microbubbles. Moreover, no cell damage was detected. Together, our data show that ultrasound-activated microbubbles can safely deliver high concentrations of drugs into urothelial cells, and have the potential to be a more efficacious alternative to traditional oral antibiotic regimes for UTI. This modality of intracellular drug delivery may prove useful in other clinical indications, such as cancer and gene therapy, where such penetration would aid in treatment.

Learning from good practice: a review of current oral health promotion materials for parents of young children

Objectives To examine the quality of UK-based oral health promotion materials (OHPM) for parents of young children aged 0-5 years old.Data sources OHPM were obtained via email request to dental public health consultants and oral health promotion teams in the UK, structured web-based searches or collected from oral health events.Data selection Materials were included if: they were freely available; they were in English; they were parent facing and included oral health advice aimed at children aged 0-5-years-old.Data extraction Quality assessment was based on: whether the oral health messages were consistent with Public Health England's Delivering better oral health guidance, and what barriers to good oral health were addressed by the OHPM using the Theoretical Domains Framework (TDF).Data synthesis A wide range of printed and digital OHPM were identified (n = 111). However, only one piece of material covered all 16 guidance points identified in Public Health England's Delivering better oral health (mean 6, SD 4), and one other material addressed all 12 domains of the TDF (mean 6, SD 2).Conclusions Although there were examples of high quality, further development is required to ensure OHPM are clear, consistent and address a wider range of barriers to good oral health behaviours.

Estimating gestational age at birth from fundal height and additional anthropometrics: a prospective cohort study

OBJECTIVE

Accurate assessment of gestational age (GA) is critical to paediatric care, but is limited in developing countries without access to ultrasound. Our objectives were to assess the accuracy of prediction of GA at birth and preterm birth classification using routinely collected anthropometry measures.

DESIGN

Prospective cohort study.

SETTING

United States.

POPULATION OR SAMPLE

A total of 2334 non-obese and 468 obese pregnant women.

METHODS

Enrolment GA was determined based on last menstrual period, confirmed by first-trimester ultrasound. Maternal anthropometry and fundal height (FH) were measured by a standardised protocol at study visits; FH alone was additionally abstracted from medical charts. Neonatal anthropometry measurements were obtained at birth. To estimate GA at delivery, we developed three predictor models using longitudinal FH alone and with maternal and neonatal anthropometry. For all predictors, we repeatedly sampled observations to construct training (60%) and test (40%) sets. Linear mixed models incorporated longitudinal maternal anthropometry and a shared parameter model incorporated neonatal anthropometry. We assessed models' accuracy under varied scenarios.

MAIN OUTCOME MEASURES

Estimated GA at delivery.

RESULTS

Prediction error for various combinations of anthropometric measures ranged between 13.9 and 14.9 days. Longitudinal FH alone predicted GA within 14.9 days with relatively stable prediction errors across individual race/ethnicities [whites (13.9 days), blacks (15.1 days), Hispanics (15.5 days) and Asians (13.1 days)], and correctly identified 75% of preterm births. The model was robust to additional scenarios.

CONCLUSIONS

In low-risk, non-obese women, longitudinal FH measures alone can provide a reasonably accurate assessment of GA when ultrasound measures are not available.

TWEETABLE ABSTRACT

Longitudinal fundal height alone predicts gestational age at birth when ultrasound measures are unavailable.

HABIT-an early phase study to explore an oral health intervention delivered by health visitors to parents with young children aged 9-12 months: study protocol

Background

Parental supervised brushing (PSB) when initiated in infancy can lead to long-term protective home-based oral health habits thereby reducing the risk of dental caries. However, PSB is a complex behaviour with many barriers reported by parents hindering its effective implementation. Within the UK, oral health advice is delivered universally to parents by health visitors and their wider teams when children are aged between 9 and 12 months. Nevertheless, there is no standardised intervention or training upon which health visitors can base this advice, and they often lack the specialised knowledge needed to help parents overcome barriers to performing PSB and limiting sugary foods and drinks.

Working with health visitors and parents of children aged 9–24 months, we have co-designed oral health training and resources (Health Visitors delivering Advice in Britain on Infant Toothbrushing (HABIT) intervention) to be used by health visitors and their wider teams when providing parents of children aged 9–12 months with oral health advice.

The aim of the study is to explore the acceptability of the HABIT intervention to parents and health visitors, to examine the mechanism of action and develop suitable objective measures of PSB.

Methods/design

Six health visitors working in a deprived city in the UK will be provided with training on how to use the HABIT intervention. Health visitors will then each deliver the intervention to five parents of children aged 9–12 months. The research team will collect measures of PSB and dietary behaviours before and at 2 weeks and 3 months after the HABIT intervention. Acceptability of the HABIT intervention to health visitors will be explored through semi-structured diaries completed after each visit and a focus group discussion after delivery to all parents. Acceptability of the HABIT intervention and mechanism of action will be explored briefly during each home visit with parents and in greater details in 20–25 qualitative interviews after the completion of data collection. The utility of three objective measures of PSB will be compared with each other and with parental-self reports.

Discussion

This study will provide essential information to inform the design of a definitive cluster randomised controlled trial.

Trial registration

There is no database for early phase studies such as ours.

What is best practice in sex and relationship education? A synthesis of evidence, including stakeholders' views

OBJECTIVES

Sex and relationship education (SRE) is regarded as vital to improving young people's sexual health, but a third of schools in England lacks good SRE and government guidance is outdated. We aimed to identify what makes SRE programmes effective, acceptable, sustainable and capable of faithful implementation.

DESIGN

This is a synthesis of findings from five research packages that we conducted (practitioner interviews, case study investigation, National Survey of Sexual Attitudes and Lifestyles, review of reviews and qualitative synthesis). We also gained feedback on our research from stakeholder consultations.

SETTINGS

Primary research and stakeholder consultations were conducted in the UK. Secondary research draws on studies worldwide.

RESULTS

Our findings indicate that school-based SRE and school-linked sexual health services can be effective at improving sexual health. We found professional consensus that good programmes start in primary school. Professionals and young people agreed that good programmes are age-appropriate, interactive and take place in a safe environment. Some young women reported preferring single-sex classes, but young men appeared to want mixed classes. Young people and professionals agreed that SRE should take a 'life skills' approach and not focus on abstinence. Young people advocated a 'sex-positive' approach but reported this was lacking. Young people and professionals agreed that SRE should discuss risks, but young people indicated that approaches to risk need revising. Professionals felt teachers should be involved in SRE delivery, but many young people reported disliking having their teachers deliver SRE and we found that key messages could become lost when interpreted by teachers. The divergence between young people and professionals was echoed by stakeholders. We developed criteria for best practice based on the evidence.

CONCLUSIONS

We identified key features of effective and acceptable SRE. Our best practice criteria can be used to evaluate existing programmes, contribute to the development of new programmes and inform consultations around statutory SRE.
