Integrating health screening for non-communicable diseases into dental services: what do we know?

This narrative review describes the impetus for health screening for non-communicable diseases in dental settings and highlights important considerations for evaluating such interventions. Real world cases are presented that showcase health screening interventions implemented in the UK. Non-communicable diseases including diabetes and cardiovascular disease are a global public health challenge. They are largely preventable by implementing lifestyle changes such as healthy eating and participation in physical activity, regular health screening for disease prevention, and/or early initiation of treatment. Hypertension case finding and control is one of the key five areas of focus for adult health, and oral health and diabetes are two of five key clinical areas for children and young people where efforts should be focused to intervene, improve outcomes and reduce inequalities. Links between oral and chronic diseases have been discussed in recent years. Therefore, screening for diabetes and cardiovascular disease has become of greater relevance to the dental profession. There is emerging evidence indicating that screening for the risk factors of cardiovascular diseases and diabetes in dental settings shows promise for improving health outcomes and may offer a cost-effective preventive approach for the detection of diabetes. Real-world services implementing health screening in dental settings have highlighted possibilities for the future and highlight the potential for the role of the dental team in detecting chronic diseases.

Dental Public Health in Action: Delivering a domestic violence and abuse screening and identification training programme in North Staffordshire-based dental practices.

Domestic violence and abuse (DVA) is a significant public health problem both globally and in the UK. Dental professionals are aptly place to detect the signs of DVA and support patients to disclose DVA. However, dental professionals may lack confidence to identify and refer patients experiencing DVA; training needs in these areas were identified in Staffordshire. Glow DVA charity and the local Dental Public Health teams worked collaboratively to develop DVA training and resources specific to the needs to the dental team; these were provided to participating dental practices in the North-Staffordshire region. Feedback from the training was positive and the training was refined to better meet the needs of the dental team.mKey challenges included obtaining dental team buy in, securing funding for the continuation of the initiative and minimising the disruption to the dental team when attending training sessions or when managing a DVA disclosure. The implementation of the training highlighted the importance of DVA champions within the third sector organisations to develop and evolve the project, within dental practices to support implementation, and within the local Dental Public Health team to facilitate dental team buy-in and sustained engagement. Future plans include developing the patient-facing resources, finding ways to formally accredit dental teams for taking part in the DVA programme, and evaluating the impact of the training programme on DVA screening, identification and referral.

Dental public health in action: foundation dentists' delivery of an oral health promotion outreach project for people experiencing homelessness in London.

Dental public health in action: foundation dentists' delivery of an oral health promotion outreach project for people experiencing homelessness in London.Within a decade, the UK has seen a dramatic increase in homelessness. This is defined as being without an available home that could reasonably be occupied. The increase has been driven by increasing poverty, welfare reform, cuts to public services and lack of affordable housing (Bramley et al., 2015; Fitzpatrick et al., 2013; Fitzpatrick et al., 2018). Rough sleeping in England alone has increased by 2,909 people or 165% since 2010 (Ministry of Housing, Communities and Local Government, 2018). This increase has been particularly visible in London (National Audit Office, 2018), where approximately a quarter of the country's rough sleepers reside (Ministry of Housing, Communities and Local Government, 2018).

Population-based study of the sensitivity of axillary ultrasound imaging in the preoperative staging of node-positive invasive lobular carcinoma of the breast.

BACKGROUND: Preoperative staging of the axilla is important to allow decisions regarding neoadjuvant treatment and the management of the axilla. Invasive lobular carcinoma metastases are difficult to detect because of the infiltrative pattern of the nodal spread. In this study the sensitivity of preoperative axillary staging between invasive lobular (ILC) and ductal (IDC) carcinoma was compared. METHODS: All women diagnosed with pure ILC or IDC in the West of Scotland in 2012-2014 were identified from a database maintained prospectively within the Managed Clinical Network. Pretreatment axillary ultrasound imaging (AUS), core biopsy and fine-needle aspiration cytology (FNAC) results were compared between ILC and IDC. RESULTS: Some 602 women with ILC and 4199 with IDC had undergone axillary surgery, of whom 209 and 1402 respectively had nodal metastases. Pretreatment AUS sensitivity was significantly lower in ILC than in IDC (32·1 versus 50·1 per cent respectively, P < 0·001; OR 0·47, 95 per cent c.i. 0·34 to 0·64). Core biopsy had equally high sensitivity of 86 per cent in both subtypes; however, FNAC was significantly less sensitive in both ILC (55 per cent; P = 0·003) and IDC (75·6 per cent; P = 0·006). Multivariable analysis revealed that cT3-4 status and symptomatic presentation were both significant in predicting nodal metastasis in patients with ILC and false-negative AUS findings (OR 3·77, 95 per cent c.i. 1·69 to 8·42, P = 0·001; and OR 1·92, 1·24 to 2·98, P = 0·003, respectively). CONCLUSION: AUS is inferior in detecting axillary node metastasis in ILC compared with IDC. Women with cT3-4 lobular carcinoma may benefit from ultrasound-guided axillary biopsy regardless of the ultrasonographic appearance of the nodes.

The dental public health implications of cosmetic dentistry: a scoping review of the literature.

INTRODUCTION: The popularity of cosmetic surgery has seen a rapid increase recently, with the trend mirrored in dentistry. The Department of Health expressed concerns about the potential for biological and psychosocial harm of these cosmetic procedures. Furthermore, the dental public health implications (DPH) of the growing uptake of cosmetic dental procedures have not been explored. OBJECTIVES: Conduct a scoping review to explore the DPH implications of cosmetic dentistry and identify gaps for future research. METHODS: A fivestage scoping review was conducted of studies identified using the search terms cosmetic AND dentistry. Data from the studies meeting the inclusion criteria were extracted, collated and summarised into themes. RESULTS: Fifty-seven papers met the inclusion criteria (11 cross-sectional studies, 10 literature reviews and 36 opinion pieces). The DPH implications were summarised into five emergent themes: dento-legal and ethical, marketing, psychosocial, biological and workforce. These themes revealed patients' increased expectations, expanding commercialisation of the profession, psychological risks to vulnerable patients, the iatrogenic consequences of invasive cosmetic dental procedures and workforce implications of the current trends. CONCLUSIONS: The scoping review found that existing literature on cosmetic dentistry is predominately anecdotal - professional opinions and discussions. Despite this, our findings demonstrated workforce training and governance implications due to increased demand for cosmetic dentistry. Further empirical research is needed to understand the DPH implications of the increasing demand and uptake of cosmetic dental procedures to guide evidence-based policy to safeguard patients and improve the quality of dental services.

Challenges identified in a pilot outreach dental service for Traveller children in Hackney, East London.

IMPETUS FOR ACTION: Inequity of dental health and dental service use for Travellers in the UK. National guidance on improving community oral health, stresses an imperative to involve and engage with "those whose economic, social and environmental circumstances or lifestyle place them at high risk of poor oral health or make it difficult for them to access dental services". SOLUTION: Oral health promotion and simple treatments were provided on two Traveller sites from a mobile dental unit (MDU) over a 5-day period and patients with extensive oral disease were referred to a fixed-site clinic for continued care. OUTCOMES: Most children, 60%, reportedly brushed once daily or less, only 40% brushed twice daily. Obvious visual caries were evident in 23 out of the 35 children (66%). A moderate to high risk of developing future caries was identified in 92% of Traveller children based on their existing diet, oral hygiene practices and caries experience. FUTURE: Oral care was successfully provided on an MDU, but this is an expensive resource and should not be considered a permanent solution. Oral health promotion messages delivered in the families' homes or local community settings through their established health services, such as health visitors or community nurses, may help to reinforce good oral hygiene and diet practices and needs robust evaluation.

Point of care HIV testing in dental settings in high-income countries: A mixed-methods systematic review.

OBJECTIVES: Expanding HIV testing beyond specialized services has been a key strategic approach to eliminating the transmission of HIV. In recent years, dental settings have been identified as offering an opportunity for delivering point of care HIV testing (POCT) interventions. Intervention components and implementation strategies have varied across studies and there is uncertainty about the prevalence of undiagnosed HIV in the dental patient population. Therefore, this systematic review aimed to synthesize the HIV testing outcomes of intervention studies, identify the core components of POCT interventions implemented in dental settings; and understand the barriers and facilitators to intervention implementation. METHODS: A mixed-methods systematic review was undertaken. Two authors reviewed abstracts and full papers for inclusion and appraised the studies using the Mixed Methods Appraisal Tool. A convergent integrated mixed methods study design underpinned the synthesis. Outcomes were presented using descriptive statistics. Intervention components were mapped to the Template for Intervention Description and Replication (TIDieR) checklist. Barriers and facilitators were described using a narrative thematic analysis. RESULTS: POCT was offered to 22 146 dental patients, 62.5% accepted POCT. Intervention studies that reported higher uptake of testing utilized a dedicated dental or researcher staff member to provide testing, integrated testing and provided results within the routine dental appointment and adopted a provider-initiated universal approach to offering testing. Six themes emerged that were pertinent to the barriers and facilitators to HIV testing in dental setting. CONCLUSIONS: POCT uptake in dental settings was comparable with other non-specialized health settings. Key to the operationalization of the intervention were perceptions about its value and relevance to the dental patient population, attitudes toward the intervention, logistical barriers to its implementation, the risk of HIV testing stigma to the patient-practitioner relationship and maximising the fit of the intervention within the constraints of the dental setting.

Embedding patient and public involvement into a doctoral study: developing a point-of-care HIV testing intervention for dental settings.

Introduction: Patient and Public Involvement (PPI) can have a positive impact on research. PPI can make research more meaningful and appropriate as well as preventing research waste. For decades, patient advocates with HIV have played a key part in public health and research. This article presents the PPI activity undertaken during a doctoral study. The aim of this article is to demonstrate how PPI was embedded into a doctoral study that explored the feasibility of HIV testing in dental settings. Methods: Patients and the public were invited to be involved with the feasibility study through various organisations and charities. A comprehensive PPI activity strategy was devised, and appropriate funding was obtained. Patients and the public were predominantly consulted or collaboratively involved with several aspects of the study. Findings: Patients and the public positively contributed to the intervention development and the resources supporting its implementation. As a result, the study resources (i.e., questionnaire and information leaflets) were easier to read, and the intervention was more appropriate to the needs of patients. Furthermore, the training and focus groups conducted with dental patients and people with HIV benefitted from input of people with lived experience. Conclusions: PPI can be embedded within doctoral studies provided there is sufficient funding, flexibility, and supervisory support. However, PPI activity may be impacted by limited resource and a priori research protocol and funding agreements.

Oral health-related stigma: Describing and defining a ubiquitous phenomenon.

This paper is the fourth of a series of narrative reviews to critically rethink underexplored concepts in oral health research. The series commenced with an initial commissioned framework of Inclusion Oral Health, which spawned further exploration into the social forces that undergird social exclusion and othering. The second review challenged unidimensional interpretations of the causes of inequality by bringing intersectionality theory to oral health. The third exposed how language, specifically labels, can perpetuate and (re)produce vulnerability by eclipsing the agency and power of vulnerabilised populations. In this fourth review, we revisit othering, depicted in the concept of stigma. We specifically define and conceptualize oral health-related stigma, bringing together prior work on stigma to advance the robustness and utility of this theory for oral health research.

Routine four-quadrant cavity shaving at the time of wide local excision for breast cancer reduces re-excision rate.

INTRODUCTION: Breast conservation therapy (BCT) has been shown to have comparable long-term survival outcomes when compared with mastectomy. Clearance of excision margin is one of the mainstays of the surgical treatment, which if not achieved at the first operation of BCT results in the need for subsequent surgery. METHODS: This study evaluated the impact of routinely taken cavity shavings on re-excision rates. This retrospective two-centre study describes the use of routine four-quadrant cavity shaving in 449 patients with consecutively treated with wide local excision for invasive cancer or ductal carcinoma in situ. RESULTS: The overall incomplete excision rate was 10.6%. Routine cavity shaving prevented the need for re-excision in 84 patients (18.7%) and identified the need for further re-excision in 33 patients (7.3%). Median time from surgery to radiotherapy was 50 days (range 13-209) for non-re-excised patients versus 78 days (range 47-260) for re-excised patients (p<0.001). Median time to chemotherapy (n=75) was 44 days (range 14-106) for non-re-excised patients versus 56 days (range 35-116) for re-excised patients (p=0.017). CONCLUSIONS: This study demonstrates that routine cavity shaving decreases re-excision rate in patients treated with wide local excision and prevents delays to adjuvant treatment due to incomplete excision.

Comparison of visual and automated assessment of Ki-67 proliferative activity and their impact on outcome in primary operable invasive ductal breast cancer.

BACKGROUND: Immunohistochemistry of Ki-67 protein is widely used to assess tumour proliferation, and is an established prognostic factor in breast cancer. There is interest in automating the assessment of Ki-67 labelling index (LI) with possible benefits in handling increased workload, with improved accuracy and precision. PATIENTS AND METHODS: Visual and automated assessment of Ki-67 LI and survival were examined in patients with primary operable invasive ductal breast cancer. Tissue microarrays (n=379 patients) immunostained for Ki-67 were scored visually and automatically with the Slidepath Tissue IA system. RESULTS: Visual and automated Ki-67 LI were in excellent agreement (ICCC=0.96, P<0.001). On univariate analysis, visual (P<0.001) and automated Ki67 LI (P<0.05) were associated with cancer-specific survival in patients with invasive ductal breast cancer overall and in patients who received endocrine therapy (Tamoxifen) (P<0.01 for visual and P<0.05 for automated scoring). CONCLUSION: Automated assessment of Ki-67 LI would appear to be comparable to visual Ki-67 LI. However, automated Ki-67 LI assessment was inferior in predicting cancer survival in patients with breast cancer, including patients who received Tamoxifen.

Expression of sphingosine 1-phosphate receptor 4 and sphingosine kinase 1 is associated with outcome in oestrogen receptor-negative breast cancer.

BACKGROUND: We previously reported that sphingosine 1-phosphate receptor 4 (S1P(4)) is expressed and stimulates the ERK-1/2 pathway via a human epidermal growth factor receptor 2 (HER2)-dependent mechanism in oestrogen receptor-negative (ER(-)) MDA-MB-453 breast cancer cells. METHODS: Clinical relevance of S1P(4) and sphingosine kinase 1 (SK1, which catalyses the formation of S1P) was assessed in a cohort of 140 ER(-) breast tumours by immunohistochemistry (IHC) and the weighted histoscore method. Additional evidence for a functional interaction between S1P(4) and SK1 and between HER2 and SK1 was obtained using MDA-MB-453 cells. RESULTS: High S1P(4) expression is associated with shorter disease-free (P=0.014) and disease-specific survival (P=0.004), and was independent on multivariate analysis. In addition, patients with tumours that contain high and low levels of SK1 and S1P(4), respectively, have a significantly shorter disease-free survival (P=0.043) and disease-specific survival (P=0.033) compared with patients whose tumours contain both low S1P(4) and SK1 levels. In addition, high tumour expression of SK1 was significantly associated with shorter disease-specific survival (P=0.0001) in patients with HER2-positive tumours. Treatment of MDA-MB-453 cells with the SK1 inhibitor, SKi (2-(p-hydroxyanilino)-4-(p-chlorophenyl)thiazole) reduced the basal and S1P/S1P(4)-induced activation of ERK-1/2 and altered HER2 trafficking in these cells. CONCLUSION: These findings highlight an important role for S1P(4) and SK1 in ER(-) breast cancer progression.

The relationship between components of tumour inflammatory cell infiltrate and clinicopathological factors and survival in patients with primary operable invasive ductal breast cancer.

BACKGROUND: The importance of the components of host local inflammatory response in determining outcome in primary operable ductal invasive breast cancer is not clear. The aim of this study was to examine the relationship between components of the tumour inflammatory cell infiltrate and standard clinicopathological factors including hormone status (oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor (HER)-2), Ki-67 and survival in patients with primary operable invasive ductal breast cancer. METHODS: Tumour inflammatory cell infiltrate, hormone status (ER, PR and HER-2), Ki-67 and standard clinicopathological factors were determined using routine pathological and immuno-histochemical techniques in 468 patients. RESULTS: The large majority (94%) of ductal tumours had evidence of inflammatory cell infiltrate. The general inflammatory cell infiltrate was positively associated with high grade (P<0.001), the absence of ER (P<0.001), the absence of PR (P<0.01), the presence of vascular invasion (P<0.05) and high lymphocytic infiltrate, plasma cell infiltrate, other inflammatory cell infiltrate and macrophage infiltrate (all P<0.001). The median follow-up of the survivors was 165 months. During this period, 93 patients died of their cancer. On univariate analysis, stratified for ER status, tumour size (P<0.01), lymph node involvement (P<0.001), tumour plasma cell infiltrate (P<0.001), other inflammatory cell infiltrate (P<0.05) and treatment (P<0.05) were associated with poorer cancer-specific survival whereas lymphocyte infiltrate (P<0.001) was associated with improved cancer-specific survival. On multivariate analysis, stratified for ER status, lymph node involvement (P<0.05) was independently associated with poorer cancer-specific survival whereas increased tumour lymphocyte infiltrate (P<0.001) was independently associated with improved cancer-specific survival. CONCLUSION: The results of this study show that, using routine histology, the general inflammatory cell infiltrate was a common feature and was positively associated with high grade, the absence of ER, the absence of PR, the presence of vascular invasion and high-grade infiltration of lymphocytes, plasma cells, other inflammatory cells and macrophages. Also, that within a mature cohort of patients, a high lymphocytic infiltrate was associated with improved survival, independent of clinicopathological characteristics including ER status, in primary operable ductal invasive breast cancer. These results rationalise previous work and provide a sound basis for future studies in this important area of breast cancer research.

Ten-year follow-up of skin-sparing mastectomy followed by immediate breast reconstruction.

BACKGROUND: The oncological safety of skin-sparing mastectomy (SSM) followed by immediate breast reconstruction (IBR) is debated owing to a presumed compromise in the completeness of mastectomy. Current evidence is poor as it is based mostly on short-term follow-up data from highly selected patients. METHODS: A prospectively maintained institutional database was searched to identify patients who underwent SSM and IBR between 1995 and 2000. A retrospective review of medical records was carried out, including only patients with ductal carcinoma in situ and invasive breast cancer. During this time all patients treated with mastectomy were offered IBR regardless of tumour stage. RESULTS: Follow-up data from 253 consecutive patients with IBR were reviewed. Patients with incomplete follow-up data and those undergoing SSM for recurrent disease following previous lumpectomy were disregarded, leaving 207 for analysis. Offering IBR to all women requiring mastectomy resulted in a large proportion of patients with advanced disease. During a median follow-up of 119 months, 17 (8·2 per cent) locoregional, six (2·9 per cent) local and 22 (10·6 per cent) distant recurrences were detected; the overall recurrence rate was 39 (18·8 per cent). Overall recurrence rate was associated with axillary lymph node metastasis (P = 0·009), higher stage (P < 0·001) and higher tumour grade (P = 0·031). The breast cancer-specific survival rate was 90·8 per cent (19 of 207 women died from recurrence). CONCLUSION: Based on these long-term follow-up data, SSM combined with IBR is an oncologically safe treatment option regardless of tumour stage.

Impact of national guidelines on family history breast cancer surveillance.

The breast cancer risk of women already under family history surveillance was accurately assessed according to national guidelines in an attempt to rationalize the service. Women attending two breast units in Glasgow between November 2003 and February 2005 were included. One thousand and five women under annual surveillance were assessed and had their relatives diagnoses verified. Four hundred and ninety-seven women were at significantly increased risk and eligible for follow-up. Five hundred and eight (50%) women attending were not eligible for family history surveillance, and 498 (98%) of these women accepted discharge. In conclusion, national guidelines have helped to more clearly define women who should undergo surveillance. This avoids unnecessary and potentially harmful routine investigations, and the service has been improved.

The effect of postoperative complications on survival and recurrence after surgery for breast cancer: A systematic review and meta-analysis.

BACKGROUND: This systematic review investigated the impact of complications on long term outcomes for patients with primary invasive operable breast cancer. METHODS: A systematic review was performed using appropriate keywords, and meta-analysis using a random effects model completed. RESULTS: Ten retrospective cohort studies, including 37,657 patients were included. Five studies identified a relationship between wound complications, infection and pyrexia and recurrence or recurrence-free survival. Risk of recurrence, 1-year and 5-year recurrence-free survival and overall survival were related to complications, particularly for patients with poor Nottingham Prognostic Index. Five studies failed to demonstrate a relationship between complications and prognosis. Complication was found to significantly affect 5-year recurrence-free survival (HR 1.48 95 % CI 1.02-2.14, p = 0.04) but not recurrence (HR 2.39, 95 %CI 0.94-6.07, p = 0.07), with a high degree of heterogeneity amongst analysed studies (I2 = 95 %). DISCUSSION: Further research is needed to quantify the effects of postoperative complication on prognosis following surgery for breast cancer.

A pilot denture service collaboration between Den-Tech denture charity and Crisis at Christmas Dental Service (CCDS): A Plan-Do-Study-Act analysis.

Introduction The Crisis at Christmas Dental Service (CCDS) provides dental treatment for homeless and vulnerably housed people each year during the Christmas period. In 2017, Den-Tech piloted a same-day field-laboratory denture service alongside CCDS to provide new dentures, additions and repairs for people experiencing social exclusion who have limited access to dental care.Objectives To evaluate the service in terms of: (i) treatment need for denture service; (ii) patient-reported feedback; (iii) clinician-reported feedback; and (iv) learning outcomes from the pilot denture service.Methods Clinicians recorded their dental activity on a standard pro forma and records of the dentures were maintained by the Den-Tech volunteer laboratory technicians. Patient feedback was collected on standardised feedback forms at the dental reception and volunteer feedback was collected via an online survey. The team undertook a quality improvement evaluation using the Plan-Do-Study-Act methodology.Results During the seven-day treatment period in 2017, 24 dentures were produced by the Den-Tech technicians, and in 2018, 31 dentures were created for people experiencing homelessness. In 2017, feedback was collected from 353 patients who attended the service: 99.4% were satisfied with their treatment and 98.3% would have recommended the service to others. Similarly, high levels of positive feedback were received in 2018. Of the dental volunteers who responded, 97.8% of volunteers felt that the denture service benefitted the patients.Conclusions The Den-Tech denture service was well-received by patients and volunteers alike. For the first time at Crisis at Christmas, patients were able to have dental extractions and immediate replacement of these teeth without compromising their dignity and overall appearance.Learning outcomes A quality improvement project utilising real-time volunteer and patient feedback can be a useful tool in reflecting upon the challenges and successes of a service as well as supporting its continual development.

Poor survival outcomes in HER2-positive breast cancer patients with low-grade, node-negative tumours.

We present a retrospective analysis on a cohort of low-grade, node-negative patients showing that human epidermal growth factor receptor 2 (HER2) status significantly affects the survival in this otherwise very good prognostic group. Our results provide support for the use of adjuvant trastuzumab in patients who are typically classified as having very good prognosis, not routinely offered standard chemotherapy, and who as such do not fit current UK prescribing guidelines for trastuzumab.

Axillary Surgery Following Neoadjuvant Chemotherapy - Multidisciplinary Guidance From the Association of Breast Surgery, Faculty of Clinical Oncology of the Royal College of Radiologists, UK Breast Cancer Group, National Coordinating Committee for Breast Pathology and British Society of Breast Radiology.

AIMS: These multidisciplinary guidelines aim to provide clinically helpful, evidence-based recommendations on the surgical management of the axilla in patients who have received neo-adjuvant chemotherapy for early breast cancer. MATERIALS & METHODS: Following a review of published evidence, a writing group representing all disciplines quorate within a breast cancer multidisciplinary meeting prepared the guidelines. KEY RECOMMENDATIONS: In patients presenting with clinically node negative axillae, sentinel node biopsy (SNB) may be performed prior to or on completion of neo-adjuvant chemotherapy (NACT). In patients presenting with clinically node positive axillae, SNB may be safely considered following completion of NACT. Four nodes should be removed with dual mapping. If evidence of complete pathological response of previous metastases is seen, axillary radiotherapy may be offered. If residual cancer (isolated tumour cells, micro- or macrometastes) is seen within the SNB, offer axillary node dissection.
