Abstract
A wide range of diabetes-directed interventions - including novel medications, devices and comprehensive education programmes - have been shown to be effective in clinical trials. But in the real world of diabetes care their efficacy is often dependent upon on how well a clinician is able to support personal engagement and motivation of the person with diabetes to use these new tools and knowledge consistently, and as directed. Although many person-centred motivational and behavioural strategies have been developed, for example, action planning, motivational interviewing and empowerment-based communication, the sheer number and apparent lack of clear differences among them have led to considerable confusion. The primary goal of this review, therefore, is to provide a practical framework that organizes and structures these programmes to enhance their more systematic use in clinical care. Its purpose is to enhance clinician efforts to respectfully encourage and support engagement and motivation for behaviour change in people with diabetes. The three-step framework for organizing and describing the specific clinical processes involved is based on self-determination theory and includes: clinician preparation for a different type of clinical encounter, clinician/person with diabetes relationship building, and clinician utilization of specific behavioural tools. We conclude with practical considerations for application of this framework to the real world of clinical care.

Abstract
AIM To determine the cross-sectional and longitudinal associations between diabetes distress and diabetes management. METHODS In a non-interventional study, 224 adults with Type 1 diabetes were assessed for diabetes distress, missed insulin boluses, hypoglycaemic episodes, and HbA1c at baseline and 9 months. RESULTS At baseline, greater distress was associated with higher HbA1c and a greater percentage of missed insulin boluses. Longitudinally, elevated baseline distress was related to increased missed insulin boluses, and decreases in distress were associated with decreases in HbA1c . In supplementary analyses, neither depression symptoms nor a diagnosis of major depressive disorder was associated with missed insulin boluses, HbA1c or hypoglycaemic episodes in cross-sectional or longitudinal analyses. CONCLUSIONS Significant cross-sectional and longitudinal associations were found between diabetes distress and management; in contrast, no parallel associations were found for major depressive disorder or depression symptoms. Findings suggest that elevated distress may lead to more missed insulin boluses over time, suggesting a potential intervention target. The covarying association between distress and HbA1c points to the complex and likely interactive associations between these constructs. Findings highlight the need to address distress as an integral part of diabetes management in routine care.

Abstract
BACKGROUND Diabetes related distress is common in type 1 diabetes patients (T1D). High levels of diabetes distress are related to poor metabolic control. An instrument to evaluate diabetes distress in T1D patients is "type 1 diabetes scale-T1DDS". The aim of this study was to translate and culturally adapt the T1DDS into Brazilian culture. METHODS T1DDS scale was translated into Portuguese. Back translation was performed and evaluated by a specialists committee. Pre-test was performed with 40 T1D outpatients at State University of Campinas hospital. Internal consistency, external consistency and re-test were performed. RESULTS 72% women, mean age: 32, 1 ± 9, 7 years, mean diabetes duration: 15, 8 ± 9, 1 years, mean scholarity: 11, 5 ± 3, 6, glycosylated hemoglobin mean: 9 ± 2%. Internal consistency: Cronbach alpha of T1DDS Brazilian version was 0.93. External consistency: Spearman's coefficient between T1DDS and PAID, Brazilian version, was 0.7781; (p < 0.0001). CONCLUSIONS The T1DDS Brazilian version is a reliable tool to evaluate diabetes distress in T1D patients in the Brazilian Population. This tool can be useful in clinical care and to identify patiens at risk and in need for psychosocial intervention.

Abstract
AIMS To determine the prevalence of depression and diabetes distress in adults with Type 1 diabetes and the rate of false-positives when compared with rates of major depressive disorder. METHODS The sample consisted of 368 individuals with Type 1 diabetes, aged > 19 years. Individuals completed: the eight-item Patient Health Questionnaire depression scale (PHQ8), which was coded using four scoring criteria (scores > 10, >12 and >15, and Diagnostic and Statistical Manual of Mental Disorders 5 (DSM) algorithm scores); the Type 1 Diabetes Distress Scale; and the Structured Clinical Interview for DSM Disorders (SCID) to assess major depressive disorder. RESULTS The prevalence rates of depression according to the eight-item Patient Health Questionnaire were: score >10, 11.4%; score >12, 7.1%; score >15, 3.8%; and positive algorithm result, 4.6%. The prevalence of major depressive disorder was 3.5%; and the prevalence of at least moderate diabetes distress was 42.1%. Depending on the criterion used, the false-positive rate when using the Patient Health Questionnaire compared with the results when using the SCID varied from 52 to 71%. Of those classified as depressed on the PHQ-8 or Structured Clinical Interview for DSM Disorders, between 92.3 and 96.2% also reported elevated diabetes distress. No significant association was found between any group classed as having depression according to the PHQ8 or the SCID and HbA1c concentration. Depression was significantly associated with more other life stress, more complications and a lower level of education. CONCLUSIONS We found an unexpectedly low rate of current depression and major depressive disorder in this diverse sample of adults with Type 1 diabetes, and a very high rate of false-positive results using the Patient Health Questionnaire. Considering the high prevalence of diabetes distress, much of what has been considered depression in adults with Type 1 diabetes may be attributed to the emotional distress associated with managing a demanding chronic disease and other life stressors and not necessarily to underlying psychopathology.

Abstract
This report describes a method to fabricate high-surface-area boron-doped diamond (BDD) electrodes using so-called 'black silicon' (bSi) as a substrate. This is a synthetic nanostructured material that contains high-aspect-ratio nano-protrusions, such as spikes or needles, on the Si surface produced via plasma etching. We now show that coating a bSi surface composed of 15 μm-high needles conformably with BDD produces a robust electrochemical electrode with high sensitivity and high electroactive area. A clinically relevant demonstration of the efficacy of these electrodes is shown by measuring their sensitivity for detection of dopamine (DA) in the presence of an excess of uric acid (UA). Finally, the nanostructured surface of bSi has recently been found to generate a mechanical bactericidal effect, killing both Gram-negative and Gram-positive bacteria at high rates. We will show that BDD-coated bSi also acts as an effective antibacterial surface, with the added advantage that being diamond-coated it is far more robust and less likely to become damaged than Si.

Abstract
AIMS To identify the hypoglycemic concerns of adults with type 2 diabetes (T2D) and examine how these concerns are associated with key patient characteristics. METHODS Qualitative interviews with 16 T2D adults and 11 diabetes care providers were conducted. Survey items were then developed and submitted to exploratory factor analyses (EFAs). Construct validity was assessed by correlations with diabetes distress, anxiety and depressive symptoms, well-being, hypoglycemic fear, hypoglycemia history and glycemic control (A1C). RESULTS An EFA with 226 insulin users and 198 non-insulin users yielded 3 factors (14 items): Hypoglycemia Anxiety, Avoidance and Confidence. For both T2D groups, higher Anxiety and Avoidance were significantly associated with more hypoglycemia, lower well-being, and greater diabetes distress, depressive symptoms and hypoglycemic fear. Similar associations, in the converse direction, were found for Confidence. Among insulin users only, Anxiety was independently associated with greater emotional distress and more hypoglycemia, while Confidence was independently linked to less emotional distress and lower A1C. Avoidance was independently associated with greater emotional distress in both groups. CONCLUSIONS Using the new 14-item Hypoglycemic Attitudes and Behavior Scale (HABS), we found that hypoglycemic concerns are significant in T2D adults, are linked to emotional distress and A1C, and merit attention in clinical practice.

Abstract
The preparation of pure zeolite nanocrystals (EMT-type framework) and their silver ion-exchanged (Ag(+)-EMT) and reduced silver (Ag(0)-EMT) forms is reported. The template-free zeolite nanocrystals are stabilized in water suspensions and used directly for silver ion-exchange and subsequent chemical reduction under microwave irradiation. The high porosity, low Si/Al ratio, high concentration of sodium and ultrasmall crystal size of the EMT-type zeolite permitted the introduction of a high amount of silver using short ion-exchange times in the range of 2-6 h. The killing efficacy of pure EMT, Ag(+)-EMT and Ag(0)-EMT against Escherichia coli was studied semi-quantitatively. The antibacterial activity increased with increasing Ag content for both types of samples (Ag(+)-EMT and Ag(0)-EMT). The Ag(0)-EMT samples show slightly enhanced antimicrobial efficacy compared to that of Ag(+)-EMT, however, the differences are not substantial and the preparation of Ag nanoparticles is not viable considering the complexity of preparation steps.

Abstract
Titanium dioxide (TiO2) surfaces doped with molybdenum (Mo) were investigated to determine if their photocatalytic ability could enhance process hygiene in the brewery industry. Doping TiO2 with Mo showed a 5-log reduction in bacterial counts within 4 to 24 h and a 1-log reduction in yeast numbers within 72 h. The presence of a dilute brewery soil on the surface did not interfere with antimicrobial activity. The TiO2-Mo surface was also active in the dark, showing a 5-log reduction in bacteria within 4 to 24 h and a 1-log reduction in yeast numbers within 72 h, suggesting it could have a novel dual function, being antimicrobial and photocatalytic. The study suggests the TiO2-Mo coating could act as a secondary barrier in helping prevent the build-up of microbial contamination on surfaces within the brewery industry, in particular in between cleaning/disinfection regimes during long production runs.

Abstract
Studies have identified significant linkages between depression and diabetes, with depression associated with poor self-management behaviour, poor clinical outcomes and high rates of mortality. However, findings are not consistent across studies, yielding confusing and contradictory results about these relationships. We suggest that there has been a failure to define and measure 'depression' in a consistent manner. Because the diagnosis of depression is symptom-based only, without reference to source or content, the context of diabetes is not considered when addressing the emotional distress experienced by individuals struggling with diabetes. To reduce this confusion, we suggest that an underlying construct of 'emotional distress' be considered as a core construct to link diabetes-related distress, subclinical depression, elevated depression symptoms and major depressive disorder (MDD). We view emotional distress as a single, continuous dimension that has two primary characteristics: content and severity; that the primary content of emotional distress among these individuals include diabetes and its management, other life stresses and other contributors; and that both the content and severity of distress be addressed directly in clinical care. We suggest further that all patients, even those whose emotional distress rises to the level of MDD or anxiety disorders, can benefit from consideration of the content of distress to direct care effectively, and we suggest strategies for integrating the emotional side of diabetes into regular diabetes care. This approach can reduce confusion between depression and distress so that appropriate and targeted patient-centred interventions can occur.

Abstract
5-aminosalicylates (5-ASA) remain an important strategy in the induction and maintenance of remission of inflammatory bowel diseases especially in ulcerative colitis. The prototypical drug of this class, sulfasalazine is generally well tolerated with severe hypersensitivity reactions and hepatotoxicity also described within the literature. When approaching a patient with an adverse reaction to 5-ASA, it can be difficult to differentiate clinically between a sulfa allergy versus a 5-ASA allergy versus a malignancy. We report on a case with initial signs and symptoms suggestive of a sulfa/5-ASA allergy that was subsequently found to be malignant in nature.

Abstract
AIMS To improve patient-centred care by determining the impact of baseline levels of conscientiousness and diabetes self-efficacy on the outcomes of efficacious interventions to reduce diabetes distress and improve disease management. METHODS Adults with Type 2 diabetes with diabetes distress and self-care problems (N = 392) were randomized to one of three distress reduction interventions: computer-assisted self-management; computer-assisted self-management plus problem-solving therapy; and health education. The baseline assessment included conscientiousness and self-efficacy, demographics, diabetes status, regimen distress, emotional burden, medication adherence, diet and physical activity. Changes in regimen distress, emotional burden and self-care between baseline and 12 months were recorded and ancova models assessed how conscientiousness and self-efficacy qualified the significant improvements in distress and management outcomes. RESULTS Participants with high baseline conscientiousness displayed significantly larger improvements in medication adherence and emotional burden than participants with low baseline conscientiousness. Participants with high baseline self-efficacy showed greater improvements in diet, physical activity and regimen distress than participants with low baseline self-efficacy. The impact of conscientiousness and self-efficacy were independent of each other and occurred across all three intervention groups. A significant interaction indicated that those with both high self-efficacy and high conscientiousness at baseline had the biggest improvement in physical activity by 12 months. CONCLUSIONS Both broad personal traits and disease-specific expectations qualify the outcomes of efficacious interventions. These findings reinforce the need to change from a one-size-fits-all approach to diabetes interventions to an approach that crafts clinical interventions in ways that fit the personal traits and skills of individual people.

Abstract
AIMS To identify patient-reported obstacles to self-monitoring of blood glucose among those with Type 2, both insulin users and non-insulin users, and to investigate how obstacles are associated with frequency of self-monitoring and use of self-monitoring data. METHODS Patients with Type 2 diabetes (n = 886, 65% insulin users) who attended a 1-day diabetes education conference in cities across the USA completed a survey on current and recommended self-monitoring of blood glucose frequency, how they used self-monitoring results and perceived obstacles to self-monitoring use. Exploratory factor analysis examined 12 obstacle items to identify underlying factors. Regression analyses examined associations between self-monitoring of blood glucose use and the key obstacle factors identified in the exploratory factor analysis. RESULTS Three obstacle factors emerged: Avoidance, Pointlessness and Burden. Avoidance was the only significant independent predictor of self-monitoring frequency (β = -0.23, P < 0.001). Avoidance (β = -0.12, P < 0.01) and Pointlessness (β = -0.15, P < 0.001) independently predicted how often self-monitoring data were shared with healthcare professionals and whether or not data were used to make management adjustments (Avoidance: odds ratio = 0.74, P < 0.001; Pointlessness: odds ratio = 0.75, P < 0.01). Burden was not associated with any of the self-monitoring behavioural measures. Few differences between insulin users and non-insulin users were noted. CONCLUSIONS Obstacles to self-monitoring of blood glucose use, both practical and emotional, were common. Higher levels of Avoidance and Pointlessness, but not Burden, were associated with less frequent self-monitoring use. Addressing patients' self-monitoring-related emotional concerns (Avoidance and Pointlessness) may be more beneficial in enhancing interest and engagement with self-monitoring of blood glucose than focusing on day-to-day, behavioural issues (Burden).

Abstract
BACKGROUND Using conscious subjects, measurement of the effects of low concentrations of anaesthetic agents can allow the dynamics of onset and offset of the agent to be measured and kinetic values estimated. However, the tests have to be rapid and preferably assess cerebral function. METHODS We used a short version of the digit symbol substitution test (DSST) that allowed frequent measurement of the impairment caused by nitrous oxide. We compared 10 min of onset and offset of breathing 5% and 30% nitrous oxide in 30% oxygen, compared with 30% oxygen only. End-tidal nitrous oxide concentrations were used to predict the concentration in a central compartment, according to a range of T(1/2) values chosen to be consistent with possible cerebral blood flow values. RESULTS We studied 19 volunteers and estimated a mean response. Only 30% nitrous oxide decreased the DSST. When DSST scores were related to the values in the predicted central compartment, the best dose-effect relationship was found when the T(1/2) was 37 s, consistent with a regional blood flow of about 120 ml 100 g(-1) min(-1). CONCLUSIONS The onset of nitrous oxide effect on DSST is rapid, consistent with the perfusion of metabolically active cerebral cortical tissues. The rate of onset is greater than previous measures based on a motor test which involved the function of subcortical structures in the central nervous system.

Abstract
OBJECTIVE To test whether a structured self-monitoring of blood glucose (SMBG) protocol reduces depressive symptoms and diabetes distress. RESEARCH DESIGN AND METHODS A 12-month, cluster-randomised, clinical trial compared patients who received a collaborative, structured SMBG, physician/patient intervention with an active control. Studied were 483 insulin naïve type 2 diabetes patients (experimental = 256, control = 227) (≥ 7.5% HbA1c) from 34 primary care practices (experimental = 21, control = 13). Experimental patients used a paper tool to record a 7-point SMBG profile on each of three consecutive days prior to their quarterly physician visit. Patients and physicians interpreted SMBG results to make medication and lifestyle changes. CLINICAL TRIAL REGISTRATION NIH Trial Registry Number: NCT00674986. MAIN OUTCOME MEASURES Depressive symptoms (Patient Health Questionnaire: PHQ-8), diabetes-related distress (Diabetes Distress Scale: DDS). HbA1c and SMBG frequency were assessed quarterly; data were analysed using Linear Mixed Models (LMM) for intent-to-treat (ITT) and per protocol (PP) analyses. RESULTS ITT analyses showed significant improvement in depression and disease-related distress among experimental and control patients from baseline to 12 months (p < 0.01 in both cases) with no between-group differences. Experimental patients displayed significantly greater reductions in distress related to regimen adherence than controls. Also, experimental patients with elevated diabetes distress or depressive symptoms at baseline showed significantly greater reductions in distress and depressive symptoms than control patients at 12 months. The greater improvement in mood in the experimental than control group was independent of improvements in glycaemic control and changes in SMBG frequency. CONCLUSIONS Using well standardised measures, collaborative, structured SMBG leads to reductions, not increases, in depressive symptoms and diabetes distress over time, for the large number of moderately depressed or distressed type 2 patients in poor glycaemic control. Changes in affective status are independent of improvements in glycaemic control and changes in SMBG frequency for these patients.

Abstract
Background. In the UK, most people with mental health problems are managed in primary care. However, many individuals in need of help are not able to access care, either because it is not available, or because the individual's interaction with care-givers deters or diverts help-seeking. Aims. To understand the experience of seeking care for distress from the perspective of potential patients from "hard-to-reach" groups. Methods. A qualitative study using semi-structured interviews, analysed using a thematic framework. Results. Access to primary care is problematic in four main areas: how distress is conceptualised by individuals, the decision to seek help, barriers to help-seeking, and navigating and negotiating services. Conclusion. There are complex reasons why people from "hard-to-reach" groups may not conceptualise their distress as a biomedical problem. In addition, there are particular barriers to accessing primary care when distress is recognised by the person and help-seeking is attempted. We suggest how primary care could be more accessible to people from "hard-to-reach" groups including the need to offer a flexible, non-biomedical response to distress.
