RESUMO
Migration and homing of immune cells are critical for immune surveillance. Trafficking is mediated by combinations of adhesion and chemokine receptors that guide immune cells, in response to chemokine signals, to specific locations within tissues and the lymphatic system to support tissue-localized immune reactions and systemic immunity1,2. Here we show that disruption of leukaemia inhibitory factor (LIF) production from group 2 innate lymphoid cells (ILC2s) prevents immune cells leaving the lungs to migrate to the lymph nodes (LNs). In the absence of LIF, viral infection leads to plasmacytoid dendritic cells (pDCs) becoming retained in the lungs where they improve tissue-localized, antiviral immunity, whereas chronic pulmonary allergen challenge leads to marked immune cell accumulation and the formation of tertiary lymphoid structures in the lung. In both cases immune cells fail to migrate to the lymphatics, leading to highly compromised LN reactions. Mechanistically, ILC2-derived LIF induces the production of the chemokine CCL21 from lymphatic endothelial cells lining the pulmonary lymphatic vessels, thus licensing the homing of CCR7+ immune cells (including dendritic cells) to LNs. Consequently, ILC2-derived LIF dictates the egress of immune cells from the lungs to regulate tissue-localized versus systemic immunity and the balance between allergen and viral responsiveness in the lungs.

Atherosclerotic cardiovascular disease causes heart attacks and strokes, which are the leading causes of mortality worldwide1. The formation of atherosclerotic plaques is initiated when low-density lipoproteins bind to heparan-sulfate proteoglycans (HSPGs)2 and become trapped in the subendothelial space of large and medium size arteries, which leads to chronic inflammation and remodelling of the artery wall2. A proliferation-inducing ligand (APRIL) is a cytokine that binds to HSPGs3, but the physiology of this interaction is largely unknown. Here we show that genetic ablation or antibody-mediated depletion of APRIL aggravates atherosclerosis in mice. Mechanistically, we demonstrate that APRIL confers atheroprotection by binding to heparan sulfate chains of heparan-sulfate proteoglycan 2 (HSPG2), which limits the retention of low-density lipoproteins, accumulation of macrophages and formation of necrotic cores. Indeed, antibody-mediated depletion of APRIL in mice expressing heparan sulfate-deficient HSPG2 had no effect on the development of atherosclerosis. Treatment with a specific anti-APRIL antibody that promotes the binding of APRIL to HSPGs reduced experimental atherosclerosis. Furthermore, the serum levels of a form of human APRIL protein that binds to HSPGs, which we termed non-canonical APRIL (nc-APRIL), are associated independently of traditional risk factors with long-term cardiovascular mortality in patients with atherosclerosis. Our data reveal properties of APRIL that have broad pathophysiological implications for vascular homeostasis.

The development of innate lymphoid cell (ILC) transcription factor reporter mice has shown a previously unexpected complexity in ILC hematopoiesis. Using novel polychromic mice to achieve higher phenotypic resolution, we have characterized bone marrow progenitors that are committed to the group 1 ILC lineage. These common ILC1/NK cell progenitors (ILC1/NKP), which we call "aceNKPs", are defined as lineage-Id2+IL-7Rα+CD25-α4ß7-NKG2A/C/E+Bcl11b-. In vitro, aceNKPs differentiate into group 1 ILCs, including NK-like cells that express Eomes without the requirement for IL-15, and produce IFN-γ and perforin upon IL-15 stimulation. Following reconstitution of Rag2-/-Il2rg-/- hosts, aceNKPs give rise to a spectrum of mature ILC1/NK cells (regardless of their tissue location) that cannot be clearly segregated into the traditional ILC1 and NK subsets, suggesting that group 1 ILCs constitute a dynamic continuum of ILCs that can develop from a common progenitor. In addition, aceNKP-derived ILC1/NK cells effectively ameliorate tumor burden in a model of lung metastasis, where they acquired a cytotoxic NK cell phenotype. Our results identify the primary ILC1/NK progenitor that lacks ILC2 or ILC3 potential and is strictly committed to ILC1/NK cell production irrespective of tissue homing.

BACKGROUND: The long-term effects on people who have had COVID-19 affect nutrition and can be influenced by diet conversely. Specific nutritional guidelines, however, were scarce at the beginning of 2020, and empirical literature was also lacking. Conventional research methodologies needed to be adapted to review the available literature that could be relevant to the United Kingdom and policy documents as well as collect the views of health and care staff. The aim of this paper is to describe the method to develop consensus statements from experts to address the necessary nutritional support and what emerged from this. METHODS: A nominal group technique (NGT) was adapted to the virtual world; we purposefully selected a range of professionals (dietitians, nurses, occupational therapists, etc.) and patients with long-term effects of COVID to present them with the most updated evidence and aim to reach key guidelines to address COVID-19 recovery. RESULTS: We were able to reach consensus statements that were developed and reviewed by relevant healthcare staff at the front line to address the nutritional needs of patients recovering from COVID-19 and those suffering from its long-term effects. This adapted NGT process led us to understand that a virtual repository of concise guidelines and recommendations was needed. This was developed to be freely accessed by both patients recovering from COVID-19 and health professionals who manage them. CONCLUSIONS: We successfully obtained key consensus statements from the adapted NGT, which showed the need for the nutrition and COVID-19 knowledge hub. This hub has been developed, updated, reviewed, endorsed and improved across the subsequent 2 years.

BACKGROUND: Obesity and unemployment are complex social and health issues with underlying causes that are interconnected. While a clear link has been established, there is lack of evidence on the underlying causal pathways and how health-related interventions could reduce obesity and unemployment using a holistic approach. OBJECTIVES: The aim of this realist synthesis was to identify the common strategies used by health-related interventions to reduce obesity, overweight and unemployment and to determine for whom and under what circumstances these interventions were successful or unsuccessful and why. METHODS: A realist synthesis approach was used. Systematic literature searches were conducted in Cochrane library, Medline, SocIndex, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, and PsychInfo. The evidence from included studies were synthesised into Context-Mechanism-Outcome configurations (CMOcs) to better understand when and how programmes work, for which participants and to refine the final programme theory. RESULTS: A total of 83 articles met the inclusion criteria. 8 CMOcs elucidating the contexts of the health-related interventions, underlying mechanisms and outcomes were identified. Interventions that were tailored to the target population using multiple strategies, addressing different aspects of individual and external environments led to positive outcomes for reemployment and reduction of obesity. CONCLUSION: This realist synthesis presents a broad array of contexts, mechanisms underlying the success of health-related interventions to reduce obesity and unemployment. It provides novel insights and key factors that influence the success of such interventions and highlights a need for participatory and holistic approaches to maximise the effectiveness of programmes designed to reduce obesity and unemployment.

For several decades historians of science have interrogated the relationship between empire and science, largely focusing on European imperial powers. At the same time, scholars have sought alternatives to an early diffusionist model of the spread of modern science, seeking to capture the multi-directional and dialogic development of science and its institutions in most parts of the globe. The papers in this special issue illuminate these questions with added attention to particular claims about the exceptionalism - or not - of Islamic societies' approach to science, modernity and politics. Each contribution centres individuals and groups who engaged with science theoretically or practically, taking seriously their analytical categories and how they understood and grappled with the social, economic and intellectual transformations happening around them. Collectively, these studies make the case for Middle Eastern and Ottoman history as useful sites for furthering our field's understanding of processes of the globalization of science and how authority, politics and science have been and continue to be interconnected.
RESUMO
The pyroptotic cell death effector gasdermin D (GSDMD) is required for murine models of hereditary inflammasome-driven, IL-1ß-dependent, autoinflammatory disease, making it an attractive therapeutic target. However, the importance of GSDMD for more common conditions mediated by pathological IL-1ß activation, such as gout, remain unclear. In this study, we address whether GSDMD and the recently described GSDMD inhibitor necrosulfonamide (NSA) contribute to monosodium urate (MSU) crystal-induced cell death, IL-1ß release, and autoinflammation. We demonstrate that MSU crystals, the etiological agent of gout, rapidly activate GSDMD in murine macrophages. Despite this, the genetic deletion of GSDMD or the other lytic effector implicated in MSU crystal killing, mixed lineage kinase domain-like (MLKL), did not prevent MSU crystal-induced cell death. Consequently, GSDMD or MLKL loss did not hinder MSU crystal-mediated release of bioactive IL-1ß. Consistent with in vitro findings, IL-1ß induction and autoinflammation in MSU crystal-induced peritonitis was not reduced in GSDMD-deficient mice. Moreover, we show that the reported GSDMD inhibitor, NSA, blocks inflammasome priming and caspase-1 activation, thereby preventing pyroptosis independent of GSDMD targeting. The inhibition of cathepsins, widely implicated in particle-induced macrophage killing, also failed to prevent MSU crystal-mediated cell death. These findings 1) demonstrate that not all IL-1ß-driven autoinflammatory conditions will benefit from the therapeutic targeting of GSDMD, 2) document a unique mechanism of MSU crystal-induced macrophage cell death not rescued by pan-cathepsin inhibition, and 3) show that NSA inhibits inflammasomes upstream of GSDMD to prevent pyroptotic cell death and IL-1ß release.

Objective: Adherence to inhaled corticosteroids (ICS) is an essential part of asthma management throughout the lifespan; however, this may be particularly challenging during the transition into adulthood. This systematic review aimed to determine the prevalence and predictors of adherence to ICS in emerging adulthood.Data sources: MEDLINE, PsycINFO, EMBASE, Scopus, and CINAHL were searched with search terms for asthma, ICS, adherence, young adults, and predictors combined.Study selection: Studies with participants with diagnosed asthma, currently prescribed ICS, a mean age between 15 and 30 years and reporting the prevalence and/or assessing predictor(s) of adherence using quantitative methods were included.Results: Twenty-nine studies were identified for inclusion (K = 29, N = 187 401). A random effect meta-analysis revealed the pooled prevalence of adherence was 28% (95% CI = 20-38%, k = 16) in studies that provided quantitative information on adherence. Adherence was higher in studies with a mean age <18 years (36%; 95% CI = 36-37%, k = 4). Studies using self-report measures provided higher estimates of adherence (35%; 95% CI = 28-42%, k = 10) than studies using pharmacy refill data (20%; 95% CI = 9-38%, k = 6). A narrative review identified personality, illness perceptions, and treatment beliefs as potentially important predictors of adherence.Conclusion: Adherence is sub-optimal during emerging adulthood, particularly after age 18. More reliable and objective measures are needed to precisely characterize adherence. Greater research and practice attention to emerging adulthood are needed to guide self-management support in those living with asthma at this important lifespan stage.Systematic review registration number: CRD42018092401.

PURPOSE: People living with and beyond cancer often experience nutrition-related issues and should receive appropriate advice on nutrition that is consistent and evidence based. The aim of this study was to investigate current practice for the provision of nutritional care by healthcare professionals (HCPs) from a UK national survey produced by the National Institute for Health Research (NIHR) Cancer and Nutrition Collaboration. METHODS: An online survey sent to professional groups and networks included questions on discussing nutrition, providing information, awareness of guidelines, confidence in providing nutritional advice, training and strategies for improving nutritional management. RESULTS: There were 610 HCPs who responded including nurses (31%), dietitians (25%), doctors (31%) and speech and language therapists (9%). The majority of HCPs discusses nutrition (94%) and provides information on nutrition (77%). However, only 39% of HCPs reported being aware of nutritional guidelines, and just 20% were completely confident in providing nutritional advice. Awareness of guidelines varied between the different professional groups with most but not all dietitians reporting the greatest awareness of guidelines and GPs the least (p = 0.001). Those HCPs with a greater awareness of guidelines had received training (p = 0.001) and were more likely to report complete confidence in providing nutritional advice (p = 0.001). CONCLUSION: Whilst HCPs discuss nutrition with cancer patients and may provide information, many lack an awareness of guidelines and confidence in providing nutritional advice. To ensure consistency of practice and improvements in patient care, there is scope for enhancing the provision of appropriate nutrition education and training.

BACKGROUND: Obesity, overweight and unemployment are interlinked, with debilitating effects on mortality, health, wellbeing and quality of life. Existing interventions to reduce overweight, obesity and unemployment have addressed these challenges independent of each other with limited success. The Adding to Social capital and individual Potential In disadvantaged REgions (ASPIRE) project will develop an innovative model using a combination of skills training and health and wellbeing interventions to improve health, wellbeing, quality of life and reduce overweight, obesity and unemployment in England and France. The aim of this paper is to outline the protocol for evaluating the ASPIRE project to examine the effectiveness of the intervention and clarify the mechanisms and contextual factors which interact to achieve outcomes. METHODS: A mixed-method realist evaluation using a single-group before-and-after design will be used. The evaluation will consist of development of an initial programme theory, theory validation and refinement using quantitative and qualitative data to understand the causal mechanisms, contexts of implementation and their interactions that result in outcomes observed in ASPIRE. Primary outcomes that will be assessed are change in body weight and body mass index, reemployment and a rise on the ASPIRE participation ladder. The ASPIRE participation ladders consists of a series of 5 steps to engage participants in the project. The first step on the ladder is joining an ASPIRE hub with paid employment as the final step on the ladder. Secondary outcomes will be physical activity, diet quality, self-efficacy and health-related quality of life. Both quantitative and qualitative approaches are appropriate in this study because the use of validated questionnaires and objective measures will demonstrate how much the intervention addressed outcomes related to weight loss and reemployment and the qualitative data (photovoice) will provide insights into the contexts and experiences that are unique to participants in the project. DISCUSSION: The results from this evaluation will provide an understanding of how a model of health-related interventions which improve health, wellbeing and maintenance of a healthy lifestyle could reduce overweight, obesity and unemployment. The findings will enable the adaptation of this model for effective implementation in different contexts and circumstances.

BACKGROUND: Despite approaches to provide effective dementia training in acute care settings, little is known about the barriers and enablers to implement and embed learning into practice. We were commissioned by Health Education England to develop and evaluate a new dementia training intervention 'Dementia Education And Learning Through Simulation 2' (DEALTS2), an innovative simulation toolkit to support delivery of dementia training in acute care across England. This study aimed to explore barriers and enablers experienced by trainers implementing DEALTS2 and extent to which it impacted on delivery of training and staff clinical practice. METHODS: We conducted twelve one-day DEALTS2 train-the-trainer (TTT) workshops across England in 2017 for National Health Service Trust staff employed in dementia training roles (n = 199 trainers); each receiving a simulation toolkit. Qualitative data were collected through telephone interviews 6-8 months after TTT workshops with 17 of the trainers. Open ended questions informed by the Kirkpatrick model enabled exploration of implementation barriers, enablers, and impact on practice. RESULTS: Thematic analysis revealed six themes: four identified interrelated factors that influenced implementation of DEALTS2; and two outlined trainers perceived impact on training delivery and staff clinical practice, respectively: (i) flexible simulation and implementation approach (ii) management support and adequate resources (iii) time to deliver training effectively (iv) trainer personal confidence and motivation (v) trainers enriched dementia teaching practice (vi) staff perceived to have enhanced approach to dementia care. Trainers valued the DEALTS2 TTT workshops and adaptability of the simulation toolkit. Those supported by management with adequate resources and time to deliver effective dementia training, were likely to implement DEALTS2. Trainers described positive impacts on their teaching practice; and perceived staff had enhanced their approach to caring for people with dementia. CONCLUSIONS: Trainers explained individual and organisational barriers and enablers during implementation of DEALTS2. The flexible simulation and implementation approach were key to supporting adherence of DEALTS2. To ensure wider implementation of DEALTS2 nationally, Trusts need to allocate appropriate time to deliver effective dementia training. Future research should measure staff behaviour change, patient perspectives of the intervention, and whether and how DEALTS2 has improved health and care outcomes.

BACKGROUND: During the global COVID-19 pandemic, UK dietitians have delivered the best care to help patients recover from the infection. The present study examined the development and evaluation of care pathways to manage nutritional care of patients following COVID-19 infection prior to and after discharge. METHODS: Registered UK dietitians completed an online questionnaire comprising 26 questions about the development of a pathway, its use, evaluation and training needs. RESULTS: Of 57 responses from organisations, 37 (65%) were involved in the planning/management of nutritional care. Only 19 responses had a new or adapted COVID-19 pathway. Of these, 74% reported involvement of dietetic services, 47% reported > 1 eligibility criteria for pathway inclusion and 53% accepted all positive or suspected cases. All respondents used nutritional screening, first-line dietary advice (food first) and referral for further advice and monitoring. Weight and food intake were the most used outcome measure. All pathways addressed symptoms related to nutrition, with the most common being weight loss with poor appetite, not being hungry and skipping meals in 84% of pathways. Over half of respondents (54%) planned to evaluate their pathway and 83% reported that they were 'very or reasonably confident' in their team's nutritional management of COVID-19. Less than half (42%) reported on training needs. CONCLUSIONS: Despite challenges encountered, pathways were developed and implemented. Dietitians had adapted to new ways of working to manage nutritional care in patients prior to and after discharge from hospital following COVID-19 infection. Further work is needed to develop strategies for evaluation of their impact.

IntroductionPERTINENT is a pilot active surveillance system of infants hospitalised with pertussis in six European Union/European Economic Area countries (37 hospitals, seven sites).AimThis observational study aimed to estimate annual pertussis incidence per site from 2016 to 2018 and respective trends between 2017 and 2018. Pertussis cases were described, including their severity.MethodsWe developed a generic protocol and laboratory guidelines to harmonise practices across sites. Cases were hospitalised infants testing positive for Bordetella pertussis by PCR or culture. Sites collected demographic, clinical, laboratory data, vaccination status, and risk/protective factors. We estimated sites' annual incidences by dividing case numbers by the catchment populations.ResultsFrom December 2015 to December 2018, we identified 469 cases (247 males; 53%). The median age, birthweight and gestational age were 2.5 months (range: 0-11.6; interquartile range (IQR): 2.5), 3,280 g (range: 700-4,925; IQR: 720) and 39 weeks (range: 25-42; IQR: 2), respectively. Thirty cases (6%) had atypical presentation either with cough or cyanosis only or with absence of pertussis-like symptoms. Of 330 cases with information, 83 (25%) were admitted to intensive care units including five deceased infants too young to be vaccinated. Incidence rate ratios between 2018 and 2017 were 1.43 in Czech Republic (p = 0.468), 0.25 in Catalonia (p = 0.002), 0.71 in France (p = 0.034), 0.14 in Ireland (p = 0.002), 0.63 in Italy (p = 0.053), 0.21 in Navarra (p = 0.148) and zero in Norway.ConclusionsIncidence appeared to decrease between 2017 and 2018 in all but one site. Enhanced surveillance of hospitalised pertussis in Europe is essential to monitor pertussis epidemiology and disease burden.

BACKGROUND: There is a paucity of simulation-based dementia education programmes for acute care settings that support the development of interpersonal skills pertinent to good care. Moreover, few studies measure the effectiveness of such programmes by evaluating the persistence of practice change beyond the immediate timeframe of the workshops. We were commissioned by Health Education England (HEE) to develop and evaluate 'DEALTS 2', a national simulation-based education toolkit informed by the Humanisation Values Framework, developed at Bournemouth University and based on an experiential learning approach to facilitate positive impacts on practice. This paper describes the process of developing DEALTS 2 and the protocol for evaluating the impact of this intervention on practice across England. METHODS: Intervention development: Following an initial scoping exercise to explore the barriers and enablers of delivering the original DEALTS programme, we developed, piloted, and rolled out DEALTS 2 across England through a Train the Trainer (TTT) model. Key stakeholders were asked to critically feedback during the development process. EVALUATION DESIGN: Mixed methods approach underpinned by Kirkpatrick Model for evaluating effectiveness of training; assessing reaction, learning, behaviour, and results. Evaluation forms and telephone interviews (quantitative and qualitative) with trainers that attended TTT workshops (n = 196) and, once implemented in individual Trusts, the staff that the trainers train. CONCLUSIONS: Evaluation of implementation and impact on care delivery for people with dementia will provide evidence of effectiveness. This will support the future development of simulation-based education programmes, amidst the current complexity of pressure in resource limited healthcare settings.

BACKGROUND: Intravenous (IV) amiodarone has multiple indications including treatment of hemodynamically unstable patients and the prevention of atrial or ventricular arrhythmias after thoracic surgery. Inflammation of the vein, or phlebitis, is the most common adverse event associated with peripherally administered amiodarone. In 2017, a rise in reported phlebitis incidents was occurring at one large academic medical center. AIM: This evidence-based quality improvement initiative aimed to decrease and enhance early detection of phlebitis in patients receiving amiodarone. METHODS: Due to the variation in assessment and management standards, evidence-based practice (EBP) methodology was utilized to establish a process for quality improvement. A thorough literature search was completed, identifying evidence-based interventions to decrease phlebitis and enhance early detection. Thorough critiques of the literature and synthesis of the evidence were completed. Multidisciplinary guidelines based on the literature were created. The guidelines included interventions such as an increase in IV assessment frequency, vein selection criteria, and the utilization of a standardized grading tool for assessment. RESULTS: Phlebitis was reduced by 30%-88%. In the first 6 months post-intervention, there was a 48% reduction in phlebitis cases. In addition, the severity of phlebitis and the quality of reporting also improved dramatically. LINKING EVIDENCE TO ACTION: This evidence-based quality improvement process led to identifying relevant knowledge gaps in care that could be streamlined into everyday nursing practice to decrease patient harm. This paper describes an in-depth process of how EBP helped to quickly take a clinical inquiry and adapt change based on findings from the evidence. Other organizations can utilize EBP to solve patient safety concerns using similar processes.

This article reports the implementation of a new procedure for screening and treatment of malnutrition in a community NHS trust in England. The barriers and facilitators to implementation were assessed with staff from Integrated Community and Older People's Mental Health teams. Data from interviews and surveys were collected at baseline, 2 months after initial training and 16 months after initial training as well as following deployment of a nutrition lead to embed new developments for nutritional care. The adoption of the procedure made screening and treatment of malnutrition simpler and more likely to be actioned. The benefit of a nutrition lead and local nutrition champions to support and empower staff (avoiding reliance on training alone) was shown to drive change for nutritional care across the community. Prioritisation and commitment of leadership at the organisational level are needed to embed and sustain malnutrition screening and treatment in routine practice.

BACKGROUND: Depression and anxiety disorders are highly comorbid, and share significant symptom overlap. Whereas depression has been consistently associated with excess mortality, the association between anxiety and mortality is less clear. Our aim was to identify constellations of anxious and depressive symptoms and examine their associations with mortality. METHOD: This study considers respondents from the 1970 (n = 1203) and 1992 (n = 1402) cohorts of the Stirling County study. Symptoms of depression and anxiety were assessed using structured at-home interviews. Vital status of participants through 2011 was determined using probabilistic linkages to the Canadian Mortality Database. RESULTS: Exploratory factor analysis yielded three correlated factors in each cohort. Items loading on each factor varied slightly between cohorts, but roughly corresponded to (1) depressive symptoms, (2) anxious symptoms, and (3) somatic symptoms. The depressive factor was associated with increased risk of mortality in both the 1970 (HR: 1.35, 95% CI: 1.12, 1.62) and 1992 (HR: 1.25, 95% CI: 1.05, 1.48) cohorts. Anxious symptoms were associated with a reduced risk of mortality in the 1992 sample (HR: 0.72; 95% CI: 0.53, 0.90). Somatic symptoms were associated with a reduced risk of mortality in the 1970 sample (HR: 0.83, 95% CI: 0.69, 0.99), but an elevated risk of mortality in the 1992 sample (HR: 1.29; 95% CI: 1.11, 1.51). CONCLUSIONS: This study provides evidence that symptoms of depression and anxiety may have differential associations with early mortality. Somatic symptoms such as upset stomach and loss of appetite may be protective against mortality, perhaps through increased use of health care services. Conversely, symptoms such as weakness and cold sweats may be indicative of failing health.

PURPOSE: Non-adherence to the oral contraceptive pill (OCP) has been reported by almost half of OCP users. As the efficacy of the OCP requires daily adherence, poor adherence often leads to unplanned pregnancies in women who depend on this method of contraception. This study aims to investigate the association between habit strength and time- and place-based cues in the context of adherence to the OCP. METHODS: A cross-sectional questionnaire of 245 current OCP users with a mean age of 22.41 years (SD = 4.78) and a range of 18-52 years was conducted. The Self-Report Behavioural Automaticity Index was employed to measure habit strength. The Medication Adherence Report Scale was used and modified to refer to OCP non-adherence specifically. Additional measures were employed to assess the use of time- and place-based cues. Data were analysed using correlational analyses. RESULTS: Stronger habit strength was associated with better adherence to the OCP (r = - 0.25, p < .001). Having a fixed time of day to take the OCP was associated with habit strength and OCP adherence. Having a fixed place to store the OCP was associated with habit strength but not with OCP adherence. CONCLUSIONS: Time- and place-based cues are likely to be an important part of any intervention design to support adherence and strengthen the habit of taking the OCP. It is recommended that future replications include longitudinal study designs and analyses.

We examine the association between a six-facet model of conscientiousness and adherence to the Oral Contraceptive Pill (OCP), to investigate if these 6 facets can account for variation in adherence to the OCP. Cross-sectional data were collected from an opportunity sample of 243 female participants who were current users of the OCP, via online survey. Data were analysed using correlation and standard regression. The 60-item Chernyshenko Conscientiousness Scale (CCS), the 10-item IPIP Conscientiousness (IPIP C) subscale and the 5-item OCP Medication Adherence Report Scale (MARS) were employed. Both the total CCS (ρ = -0.26, p < 0.01) and the IPIP C scale (ρ = -0.22, p < 0.01) were associated with MARS. All facets measured by the CCS had small to medium-sized statistically significant correlations (r > -0.18 and r < -0.23, p < 0.05) with OCP adherence with the exception of traditionalism. Within a multivariable model, the six facets accounted for 7.1% of variance (p < 0.01) in adherence to the OCP. No one facet made a significant unique contribution to the model. These findings replicate and extend previous links between conscientiousness and OCP adherence. Further research should be conducted to establish the reliability of these findings in a general population of OCP users. Future interventions should focus on the development of interventions which take conscientiousness into consideration.

PURPOSE: To measure the feasibility of a communication application and an iPad to facilitate communication in postoperative patients with head and neck cancer. DESIGN: A prospective feasibility study. METHODS: This IRB-approved study was conducted in the postanesthesia care unit at an urban comprehensive cancer center. The participants included patients with head and neck cancer who underwent surgery that resulted in altered communication. Questionnaires were developed and administered to measure feasibility and patient satisfaction at different time points (preoperative, postoperative, and 1 to 4 days postoperatively). FINDINGS: Of 38 patients in the study, 25 (66%) were able to use the customized iPad. Of these 25 patients, 15 (60%) were satisfied or somewhat satisfied with it. 84% found the customized iPad to be very or somewhat helpful for communication after surgery. CONCLUSIONS: Patients were satisfied with the customized iPad, and the study found that using technology such as this was feasible in the immediate postoperative period.
