Engaging with peers to integrate community care: Knowledge synthesis and conceptual map

CONTEXT

Engaging with peers is gaining increasing interest from healthcare systems in numerous countries. Peers are people who offer support by drawing on lived experiences of significant challenges or 'insider' knowledge of communities. Growing evidence suggests that peers can serve as a bridge between underserved communities and care providers across sectors, through their ability to build trust and relationships. Peer support is thus seen as an innovative way to address core issues of formal healthcare, particularly fragmentation of care and health inequalities. The wide body of approaches, goals and models of peer support speaks volumes of such interest. Navigating the various labels used to name peers, however, can be daunting. Similar terms often hide critical differences.

OBJECTIVES/BACKGROUND

This article seeks to disentangle the conceptual multiplicity of peer support, presenting a conceptual map based on a 3-year knowledge synthesis project involving peers and programme stakeholders in Canada, and international scientific and grey literature.

SYNTHESIS/MAIN RESULTS

The map introduces six key questions to navigate and situate peer support approaches according to peers' roles, pathways and settings of practice, regardless of the terms used to label them. As a tool, it offers a broad overview of the different ways peers contribute to integrating health and community care.

DISCUSSION

We conclude by discussing the map's potential and limitations to establish a common language and bridge models, in support of knowledge exchange among practitioners, policymakers and researchers.

PATIENT OR PUBLIC CONTRIBUTION

Our team includes one experienced peer support worker. She contributed to the design of the conceptual map and the production of the manuscript. More than 10 peers working across Canada were also involved during research meetings to validate and refine the conceptual map.

The Ecology of Engagement: Fostering cooperative efforts in health with patients and communities

CONTEXT

Patients and community members are engaged in nearly every aspect of health systems. However, the engagement literature remains siloed and fragmented, which makes it difficult to connect engagement efforts with broader goals of health, equity and sustainability. Integrated and inclusive models of engagement are needed to support further transformative efforts.

METHODS

This article describes the Ecology of Engagement, an integrated model of engagement. The model posits that: (1) Health ecosystems include all members of society engaged in health; (2) Engagement is the 'together' piece of health and healthcare (e.g., caring for each other, preventing, researching, teaching and building policies together); (3) Health ecosystems and engagement are interdependent from each other, both influencing health, equity, resilience and sustainability.

CONCLUSION

The Ecology of Engagement offers a common sketch to foster dialogue on engagement across health ecosystems. The model can drive cooperative efforts with patients and communities on health, equity, resilience and sustainability.

PATIENTS AND PUBLIC CONTRIBUTION

Three of the authors have lived experiences as patients. One has a socially disclosed identity as a patient partner leader with extensive experience in engagement (individual care, education, research, management and policy). Two authors have significant experience as patients and informal caregivers, which were mobilized in descriptive illustrations. A fourth author has experience as an engaged citizen in health policy debates. All authors have professional lived experience in health (manager, researcher, health professional, consultant and educator). Six patient and caregiver partners with lived experience of engagement (other than the authors) contributed important revisions and intellectual content.

Increased risk of oropharyngeal cancers mediated by oral human papillomavirus infection: Results from a Canadian study

BACKGROUND

This study aimed to estimate the extent to which oral sex behavior is associated with an increased risk of oropharyngeal cancers (OPCs), and how much of the association is mediated by oral human papillomavirus (HPV) infection.

METHODS

We used data from a hospital-based case-control study conducted in Montreal, Canada. Information on oral sex behaviors was collected. Oral rinse and oral brush specimens were analyzed for HPV positivity and genotyping. Logistic regression estimated the odds ratios (OR) and 95% confidence intervals (CI) for the association between oral sex behaviors and OPC.

RESULTS

Onset of oral sex practice at age 16 years or younger had an increased risk of OPCs relative to those with onset after age 30 years (OR = 2.98; 95% CI 1.37-6.47). This association decreased (OR = 1.09; 95% CI 0.25-4.71) when restricted to those positive for HPV.

CONCLUSIONS

Our results suggest that the association between oral sex and OPC seems mediated by oral HPV infection.

Periodontal Diseases and Traumatic Dental Injuries in the Pediatric Population

This article provides an overview of periodontal diseases and traumatic dental injuries (TDIs) in children and adolescents, which are serious public health problems worldwide. Periodontal diseases, including gingivitis and periodontitis, commonly affect the oral soft tissues and teeth and often co-occur with other chronic diseases. TDIs are prevalent from an early age and carry high treatment costs. Behavioral and environmental factors contribute to both TDIs and periodontal diseases, but their etiology varies according to population characteristics and case definition. Both conditions may lead to pain, function impairment, esthetic problems, and psychosocial effects, with major consequences on quality of life.

Aetiological heterogeneity of head and neck squamous cell carcinomas: the role of human papillomavirus infections, smoking and alcohol

Tobacco and alcohol consumption are the main risk factors for head and neck squamous cell carcinoma (HNSCC). In addition, human papillomavirus (HPV) infection plays a causal role in oropharyngeal cancer (OPC), a subset of HNSCC. We assessed the independent effects of tobacco, alcohol and HPV infection on OPC risk in the head and neck cancer (HeNCe) Life study, a hospital-based case-control study of HNSCC with frequency-matched controls by age and sex from four Montreal hospitals. Interviewers collected information on socio-demographic and behavioural factors. We tested exfoliated oral cells for HPV DNA by polymerase chain reaction (PCR). We included only OPC cases (n = 188) and controls (n = 427) without missing values for HPV, smoking or alcohol. We examined associations by estimating odds ratios (ORs) and corresponding 95% confidence intervals (CI) using unconditional logistic regression. Smoking (OR = 1.90, 95% CI: 1.04-3.45) and alcohol (OR = 2.74, 95% CI: 1.45-5.15) were associated with an increased risk of OPC independent of HPV status. Positivity for HPV 16 among heavy smokers and heavy alcohol users was associated with a 30.4-fold (95% CI: 8.94-103.26) and 18.6-fold (95% CI: 5.75-60.13) elevation in risk of OPC relative to participants who were HPV negative, respectively. Moreover, the combined effect of heavy smoking and alcohol comsumption with HPV 16 infection substantially increased OPC risk (OR = 48.76, 95% CI: 15.83-150.17) and (OR = 50.60, 95% CI: 15.96-160.40), respectively. Our results support the independent roles of smoking, alcohol and HPV infection in OPC risk and a possible combined effect. Efforts should be made to tackle these major risk factors simultaneously.

Knowledge Transfer Statement: Mixed methods are increasingly being used in research studies on complex oral health issues. Combining quantitative and qualitative approaches, this methodology produces in-depth results of great relevance to researchers, clinicians, managers, and policy makers at each level of the oral health care system. A 5-day training program in applying oral health mixed methods research can be replicated by other institutions and contribute to capacity building and training faculty, students, and research professionals.

Human papillomavirus genotypes and risk of head and neck cancers: Results from the HeNCe Life case-control study

OBJECTIVE

Human papillomaviruses (HPV) are changing dramatically the epidemiologic landscape of head and neck cancers (HNCs). Their role in the aetiology of these cancers varies widely among HNCs subsites, sex and geographical regions worldwide. We describe HPV prevalence and its association with HNCs risk overall and by anatomical subsite in a sample of Canadians.

MATERIALS AND METHODS

The HeNCe Life study recruited 460 incident HNCs cases and 458 controls frequency-matched by age and sex from four Montreal hospitals in 2005-2013. We tested oral rinse and oral brush specimens for mucosal HPV genotypes. HPV positivity was categorized hierarchically as either negative, exclusively non-α-9 species types, α-9 types other than HPV16, and HPV16. We estimated odds ratios (OR) and 95% confidence intervals (CI) for the associations between HPV and HNCs using unconditional logistic regression, controlling for confounders.

RESULTS

The prevalence of HPV infection among controls and cases was 14.5% and 41.2% in oral rinse and 3.1% and 24.4% in oral brush samples, respectively. HPV16 was the predominant genotype with an oral rinse and oral brush prevalence of 26.3% and 16.2% among cases and 2.4% and 0.2% among controls, respectively. HPV infection was associated with an increased risk of HNCs overall (OR=4.18; 95% CI, 2.94-5.95) and oropharyngeal cancer only (OR=10.3; 95% CI, 6.8-15.7). HNCs and oropharyngeal cancer were strongly associated with HPV16 (OR=18.1; 95% CI, 9.1-35.8, and OR=47.2; 95% CI, 23.1-96.6, respectively).

CONCLUSION

HPV infection, particularly HPV16, was associated with an increased HNCs risk, most strongly for oropharyngeal cancers.

Periodontal diseases and risk of oral cancer in Southern India: Results from the HeNCe Life study

Some studies suggest that periodontal diseases increase the risk of oral cancer, but contradictory results also exist. Inadequate control of confounders, including life course exposures, may have influenced prior findings. We estimate the extent to which high levels of periodontal diseases, measured by gingival inflammation and recession, are associated with oral cancer risk using a comprehensive subset of potential confounders and applying a stringent adjustment approach. In a hospital-based case-control study, incident oral cancer cases (N = 350) were recruited from two major referral hospitals in Kerala, South India, from 2008 to 2012. Controls (N = 371), frequency-matched by age and sex, were recruited from clinics at the same hospitals. Structured interviews collected information on several domains of exposure via a detailed life course questionnaire. Periodontal diseases, as measured by gingival inflammation and gingival recession, were evaluated visually by qualified dentists following a detailed protocol. The relationship between periodontal diseases and oral cancer risk was assessed by unconditional logistic regression using a stringent empirical selection of potential confounders corresponding to a 1% change-in-estimates. Generalized gingival recession was significantly associated with oral cancer risk (Odds Ratio = 1.83, 95% Confidence Interval: 1.10-3.04). No significant association was observed between gingival inflammation and oral cancer. Our findings support the hypothesis that high levels of periodontal diseases increase the risk of oral cancer.

Inhibition of the kinase WNK1/HSN2 ameliorates neuropathic pain by restoring GABA inhibition

HSN2is a nervous system predominant exon of the gene encoding the kinase WNK1 and is mutated in an autosomal recessive, inherited form of congenital pain insensitivity. The HSN2-containing splice variant is referred to as WNK1/HSN2. We created a knockout mouse specifically lacking theHsn2exon ofWnk1 Although these mice had normal spinal neuron and peripheral sensory neuron morphology and distribution, the mice were less susceptible to hypersensitivity to cold and mechanical stimuli after peripheral nerve injury. In contrast, thermal and mechanical nociceptive responses were similar to control mice in an inflammation-induced pain model. In the nerve injury model of neuropathic pain, WNK1/HSN2 contributed to a maladaptive decrease in the activity of the K(+)-Cl(-)cotransporter KCC2 by increasing its inhibitory phosphorylation at Thr(906)and Thr(1007), resulting in an associated loss of GABA (γ-aminobutyric acid)-mediated inhibition of spinal pain-transmitting nerves. Electrophysiological analysis showed that WNK1/HSN2 shifted the concentration of Cl(-)such that GABA signaling resulted in a less hyperpolarized state (increased neuronal activity) rather than a more hyperpolarized state (decreased neuronal activity) in mouse spinal nerves. Pharmacologically antagonizing WNK activity reduced cold allodynia and mechanical hyperalgesia, decreased KCC2 Thr(906)and Thr(1007)phosphorylation, and restored GABA-mediated inhibition (hyperpolarization) of injured spinal cord lamina II neurons. These data provide mechanistic insight into, and a compelling therapeutic target for treating, neuropathic pain after nerve injury.

No role for human papillomavirus infection in oral cancers in a region in southern India

Oral cancer is a major public health issue in India with ∼ 77,000 new cases and 52,000 deaths yearly. Paan chewing, tobacco and alcohol use are strong risk factors for this cancer in India. Human papillomaviruses (HPVs) are also related to a subset of head and neck cancers (HNCs). We examined the association between oral HPV and oral cancer in a sample of Indian subjects participating in a hospital-based case-control study. We recruited incident oral cancer cases (N = 350) and controls frequency-matched by age and sex (N = 371) from two main referral hospitals in Kerala, South India. Sociodemographic and behavioral data were collected by interviews. Epithelial cells were sampled using Oral CDx® brushes from the oral cancer site and the normal mucosa. Detection and genotyping of 36 HPV genotypes were done using a polymerase chain reaction protocol. Data collection procedures were performed by qualified dentists via a detailed protocol with strict quality control, including independent HPV testing in India and Canada. HPV DNA was detected in none of the cases or controls. Associations between oral cancer and risk factors usually associated with HPV infection, such as oral sex and number of lifetime sexual partners, were examined by logistic regression and were not associated with oral cancer. Lack of a role for HPV infection in this study may reflect cultural or religious characteristics specific to this region in India that are not conducive to oral HPV transmission. A nationwide representative prevalence study is needed to investigate HPV prevalence variability among Indian regions.

[Inner city children's perceptions about well-being]

This study, carried out from the point of view of positive psychology, gave inner-city children an opportunity to express themselves. Through interviews, they shared their perceptions of psychological well-being in the context of their everyday life and the contribution of a community agency towards their well-being. The support of others appeared as a fundamental aspect of their perceptions of psychological well-being, while the enrichment provided by the agency also emerged from the data. However, children were shown to have relatively few personal strategies to improve their own well-being. The children also identified some obstacles to their well-being. A series of tailored reporting activities made it possible for the personnel and clients of the agency to appropriate the results of the study.

Reduction of animal usage by serial bleeding of mice for pharmacokinetic studies: application of robotic sample preparation and fast liquid chromatography-mass spectrometry

Typically, pharmacokinetic studies in mice require one animal per time point, thus resulting in differences due to dosing error, animal to animal variation and more importantly the euthanasia of a large number of animals. A method for the determination of pharmacokinetic data from serially bled mice to support early drug discovery is described. Sample analysis relies on liquid chromatography coupled with tandem mass spectrometry permitting robust and reproducible analysis requiring approximately 3 min per sample. Several parameters are discussed including the method of sample collection, preparation and analysis. The use of serially bled mice has lead to a remarkable reduction in animal usage and a corresponding reduction in compound required for such experiments. Using conventional methodology, a nine-point pharmacokinetic curve with four animals per time point would require 36 mice. With the method described below, only four mice in total are used and euthanasia is not required, permitting reuse after several weeks recovery and washout. Also, pharmacodynamic-pharmacokinetic correlation is possible and is demonstrated using a mouse model of diabetes.
