Cost Analysis of FreeStyle Libre ® 2 System in Type 2 Diabetes Mellitus Population. Diabetes Ther 2021; 12:2329-2342. [PMID: 33948909 PMCID: PMC8096131 DOI: 10.1007/s13300-021-01064-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Accepted: 04/20/2021] [Indexed: 12/16/2022] Open
Abstract
INTRODUCTION FreeStyle Libre® 2 system is a sensor-based flash-monitoring system that measures interstitial fluid glucose. The study aimed to compare cost of FreeStyle Libre 2 system and self-monitoring of blood glucose (SMBG) in the type 2 diabetes mellitus (T2DM) population from the Spanish Health System perspective. METHODS On the basis of data collected from a literature review, the cost of glucose monitoring was modelled for patients with T2DM on a basal-bolus insulin regimen. The cost estimate included annual consumption for glucose monitoring (strips, lancets and sensors) and severe hypoglycaemic events (SHE) management. A published rate of SHE (2.5 episodes/patient-year) was considered. A reduction of SHE (- 48.8%) associated with FreeStyle Libre 2 system, derived from the REPLACE trial, was applied. Hospital attendance for 20.5% of SHEs (with subsequent hospitalization in 16.0%) was applied. Consumption of strips and lancets was set at 6/day for SMBG (derived from national monitoring recommendations), and 0.2/day for FreeStyle Libre 2 system users, with 26 FreeStyle Libre 2 sensors/year. Unitary costs (€, year 2020 excluding VAT) were derived from literature (€0.28/strip; €0.09/lancet; €3.09/daily FM sensor; €3804/hospitalized SHE; €1794/hospital-attended non-admitted SHE; €389/community-attended SHE). RESULTS Costs were €2700 and €2120/year/patient using SMBG or FreeStyle Libre 2 system, respectively. For 1000 patients with T2DM using basal-bolus insulin, 1220 SHEs/year (with 48 hospitalizations) could be prevented and FreeSytle Libre 2 system could generate cost savings of up to €580,953/year versus SMBG (- 21.5%). CONCLUSION FreeStyle Libre 2 system is a potential cost-saving strategy in patients with T2DM in Spain on a basal-bolus insulin regimen.

The prevalence and evidence-based management of needle fear in adults with chronic disease: A scoping review. PLoS One 2021; 16:e0253048. [PMID: 34111207 PMCID: PMC8192004 DOI: 10.1371/journal.pone.0253048] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 05/27/2021] [Indexed: 11/27/2022] Open
Abstract
Background Little is known about the prevalence and best management of needle fear in adults with chronic disease, who may experience frequent and long-term exposure to needles for lifesaving therapies such as renal dialysis and cancer treatment. Identifying interventions that assist in management of needle fear and associated distress is essential to support these patients with repeated needle and cannula exposure. Method We followed the PRISMA methodology for scoping reviews and systematically searched PsychINFO, PubMed (MEDLINE), ProQuest, Embase and grey literature and reference lists between 1989 and October 2020 for articles related to needle discomfort, distress, anxiety, fear or phobia. The following chronic diseases were included: arthritis, asthma, chronic back pain, cancer, cardiovascular disease, chronic obstructive pulmonary disease, diabetes, and mental illness, or kidney failure. Literature concerning dentistry, vaccination, intravenous drug users and paediatric populations were excluded. Results We identified 32 papers reporting prevalence (n = 24), management (n = 5) or both (n = 3). Needle fear prevalence varied in disease cohorts: 17–52% (cancer), 25–47% (chronic kidney disease) and 0.2–80% (diabetes). Assessment methods varied across studies. Management strategies had poor evidence-base, but included needle-specific education, decorated devices, cognitive-behavioural stress management techniques, distraction, and changing the therapy environment or modality. Conclusion Although needle fear is common there is a paucity of evidence regarding interventions to address it among adults living with chronic disease. This scoping review has highlighted the need for improved identification of needle fear in adults and development of interventions are required for these cohorts.

Psychological Outcomes in Children and Early Adolescents With Type 1 Diabetes Following Pediatric Diabetes Summer Camp: A 3-Month Follow-Up Study. Front Pediatr 2021; 9:650201. [PMID: 33777869 PMCID: PMC7987815 DOI: 10.3389/fped.2021.650201] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Accepted: 02/05/2021] [Indexed: 01/09/2023] Open
Abstract
Objective: The aim of this study was to assess general psychosocial adjustment to diabetes and perceived disease management among patients with type 1 diabetes (T1D) and their parents before and after patients' participation in a diabetes summer camp. Methods: In this follow-up study, 20 children and adolescents with T1D (eight boys; mean age = 11.01 ± 0.94 years; mean diabetes duration = 3.02 ± 2.27) attending a southern Italian diabetic center, along with their parents, were assessed prior to and 3 months after the youths participated in a 1 week camp-based intervention involving didactic and interactive child-centered education and recreational activities. Patients and their parents completed measures assessing patients' quality of life and strategies employed by patients to cope with pain. Patients also completed measures evaluating their diabetes psychosocial adjustment, diabetes self-efficacy management, and illness perception; also, their parents completed measures of caregivers' perceived diabetes burden and treatment satisfaction. Youths' glycated hemoglobin (HbA1c) and standardized body mass index (z-BMI) values were also assessed. Within-subjects repeated-measures analyses of variance evaluated pre- and post-camp changes. Results: Camp attendance showed no beneficial effects on glycemic control, as indicated by HbA1c values both before (7.02%) and after (7.28%) camp being lower than 7.5%. HbA1c values were found to have increased after camp (pre-camp = 7.02%, post-camp = 7.28%; p = 0.010), but since they still fell within an acceptable range, they did not reveal clinically relevant changes in glycemic control. No substantial significant improvement in psychosocial measures was observed in children or parents (all p > 0.05). According to the parents' evaluation, social support-seeking as a patient pain-coping strategy was slightly increased (p = 0.044) after attending the camp. Conclusions: This study does not provide empirical evidence of benefits of participating in a diabetes camp for either patients or their parents. These findings suggest that healthcare providers rethink such camps as an experience for youths with T1D that actively involves parents and that includes both youth- and parent-focused psychological interventions.

Abstract
INTRODUCTION Compare cost of the interstitial liquid glucose flash monitoring (FM) system (FreeStyle Libre 2) versus self-monitoring of blood glucose (SMBG) in adults with type 1 diabetes mellitus (T1DM) in Spain. RESEARCH DESIGN AND METHODS A model was developed to estimate, with the perspective of the Spanish health system, the annual costs associated with glucose monitoring and hypoglycemic events management in T1DM population, with multiple insulin daily doses (MDI). According to published evidence, rate of severe hypoglycemia (SHE) of 4.90 episodes per patient-year was applied. Reduction of SHE (58.6%) was modeled associated with FM use. Published rates of hospital care (20.2%) and subsequent admission (16%) were assumed for SHE. The daily consumption of strips and lancets was 9 in patients with SMBG (before and after 4 daily intakes and at bedtime) and 0.5 for FM users (according to IMPACT trial findings). Annual consumption of 26 FM sensors was considered (1 every 14 days). Unit costs (in € of 2019, excluding VAT) were obtained from literature and national databases. Sensitivity analyses (SA) were carried out to evaluate the model robustness. RESULTS The total annual cost/patient was €4437 for SMBG and €2526 for FM. The use of FM would be associated with an annual savings in the costs of monitoring and managing hypoglycemic events of €1911 per patient-year. In a hypothetical cohort of 1000 patients with T1DM MDI, FM could avoid in 1 year 4900 SHE, 93 hospitalizations for SHE. In addition, the use of FM would generate total savings of up to €1 910 000 per year. In the SA with alternative hypoglycemia events rates and use of strips and lancets, and including non-SHE episodes, savings from €370 000 to €1 760 000 were observed with FM. CONCLUSIONS The use of the FM system to monitor glucose in adults with T1DM treated with MDI, would reduce hypoglycemic events and would result in cost savings for the health system.

Abstract
Antidiabetic therapeutics, including insulin as well as glucagon-like peptide 1 (GLP-1) and its analogs, are essential for people with diabetes to regulate their blood glucose levels. Nevertheless, conventional treatments based on hypodermic administration is commonly associated with poor blood glucose control, a lack of patient compliance, and a high risk of hypoglycemia. Closed-loop drug delivery strategies, also known as self-regulated administration, which can intelligently govern the drug release kinetics in response to the fluctuation in blood glucose levels, show tremendous promise in diabetes therapy. In the meantime, the advances in the development and use of microneedle (MN)-array patches for transdermal drug delivery offer an alternative method to conventional hypodermic administration. Hence, glucose-responsive MN-array patches for the treatment of diabetes have attracted increasing attentions in recent years. This review summarizes recent advances in glucose-responsive MN-array patch systems. Their opportunities and challenges for clinical translation are also discussed.

Abstract
AIMS The aim of this study was to evaluate the prevalence of needle fear and summarize the characteristics of individuals who exhibit this fear. BACKGROUND Injections are among the most common medical procedures, yet fear of needles can result in avoidance of preventive measures and treatment. DESIGN Systematic review and meta-analysis. DATA SOURCES MEDLINE (1966-2017), Embase (1947-2017), PsycINFO (1967-2017), and CINAHL (1961-2017) were searched, with no restrictions by age, gender, race, language, or country. REVIEW METHODS The prevalence of needle fear was calculated and restricted maximum likelihood random effects models were used for meta-analysis and meta-regression. RESULTS The search yielded 119 original research articles which are included in this review, of which 35 contained sufficient information for meta-analysis. The majority of children exhibited needle fear, while prevalence estimates for needle fear ranged from 20-50% in adolescents and 20-30% in young adults. In general, needle fear decreased with increasing age. Both needle fear and needle phobia were more prevalent in females than males. Avoidance of influenza vaccination because of needle fear occurred in 16% of adult patients, 27% of hospital employees, 18% of workers at long-term care facilities, and 8% of healthcare workers at hospitals. Needle fear was common when undergoing venipuncture, blood donation, and in those with chronic conditions requiring injection. CONCLUSIONS Fear of needles is common in patients requiring preventive care and in those undergoing treatment. Greater attention should be directed to interventions which alleviate fear in high-risk groups.

Abstract
Needle-based delivery systems suit the vast majority of people with type 1 and type 2 diabetes who require insulin. However, a small group may be better suited to a needle-free delivery system. In the UK, GPs can now prescribe, on the NHS, such a needle-free delivery system — sometimes called a jet injector. These devices are not necessarily pain free but they have a well-established history and offer patients and their healthcare professionals a credible alternative to a needle-based insulin injection.

Why do few food-allergic adolescents treat anaphylaxis with adrenaline?--Reviewing a pressing issue. Pediatr Allergy Immunol 2013; 24:222-9.

Abstract
Food allergic adolescents are at higher risk of fatal anaphylaxis than other children. Both allergen avoidance and maintaining access to adrenaline auto-injectors (AAI) are key goals in effective food allergy management, for which written guidance is often supplied. However, adolescents are rarely sufficiently prepared to use adrenaline during anaphylaxis. It is likely that further didactic education would bring limited improvement in management in this population. Focused discussion of each adolescent's perspectives and current management practice may allow more effective behavioural strategies to be adopted. Key areas for appraisal include subjects' experiences after previous allergen exposure with reference to worst response, recognising specific symptoms requiring AAI administration, and appropriate priority being given to timeliness of administering adrenaline. Behavioural strategies should be discussed to increase AAI accessibility. Rigor of allergen avoidance should not be compromised by false reassurance of proximity to emergency medication or medical services. Food allergic adolescents are motivated by the psychological impact of their condition, which often makes them feel different to their peers and may result in bullying. Methods of appropriately empowering adolescents may be considered, such as involvement of close friends and lay organisations to support appropriate management. Open discussion is crucial in engaging with adolescents' reasoning for adopting their chosen management strategies. Further research is warranted to identify cognitive patterns associated with high-risk behaviour, and to design appropriate interventions for the augmentation of adolescent self-management skills.

Abstract
BACKGROUND Insulin is an essential treatment for both type 1 and 2 diabetes. Among the available routes of insulin administration, oral delivery is the most appealing option. OBJECTIVE The purpose of this study was to evaluate the pharmacodynamic and pharmacokinetic profiles of orally administered enteric insulin and compare the time-action of these oral insulin capsules with neutral protamine Hagedorn (NPH) insulin. METHODS This was a single-center, randomized, 4-period, crossover study. Twelve healthy volunteers (3 per group) received 1 of 3 doses of oral enteric insulin (50, 100, or 200 U) or 1 subcutaneous injection of NPH insulin (6 U) on 4 separate days. After administration, glucose infusion rates and serum insulin concentrations were monitored for 10 hours. RESULTS Glucose infusion rates increased after administration of either NPH or oral enteric insulin. The mean times for maximal metabolic effects for 50, 100, and 200 U of oral enteric insulin were 250 (118), 170 (58), and 236 (132) minutes, respectively, compared with 243 (79) minutes for NPH insulin. The onset of action was slower for oral enteric insulin at 50 U (38 [10] minutes), 100 U (41 [18] minutes), and 200 U (65 [58] minutes) compared with NPH insulin (35 [8] minutes). The maximum glucose infusion rates for oral enteric insulin treatment (1.66 [0.50], 1.61 [1.00], and 1.80 [0.60] mg/kg/min for 50, 100, and 200 U, respectively) were lower compared with NPH insulin (2.06 [0.82] mg/kg/min), although these differences were not statistically significant. CONCLUSIONS Oral enteric insulin capsules induced significant glucodynamic effects and exhibited a time-action profile similar to that of NPH insulin in these healthy volunteers. No detectable increases in serum insulin concentration were observed in any treatment group. Trial registry number: ChiCTR-TRC-12001872.

Abstract
OBJECTIVE To explore the nature and management of needle-related distress in children and adolescents with cystic fibrosis (CF). DESIGN Qualitative study using semi-structured interviews. METHODS Fourteen child-parent dyads took part. Children (5 male; 9 female) had a mean age of 12.4 years (range 7-17) and were mostly diagnosed with CF at birth (N= 11). Frequency of needle procedures ranged from once to six times a year. Parents (3 male; 11 female) had a mean age of 41.5 years and were from a variety of socio-economic backgrounds. Interviews were transcribed and analysed using thematic analysis. RESULTS Most participants identified previous needle experiences and pain as related to their needle anxiety. Over half of parents and children considered 'taking control' to be the optimum coping strategy. The majority of parents and children thought inhaled nitrous oxide gas during needle procedures was helpful in managing needle-related distress. Parent and staff influences on needle-related distress are also examined. CONCLUSIONS Needle-related distress in children with CF has a substantial impact on children and their parents, and may lead to management problems and treatment refusal. Psychological and pharmacological interventions could reduce distress and aid management.

Abstract
OBJECTIVE This study evaluated insulin injection coping by parental report and video observation in children 3 to <11 years old with diabetes. METHODS Caregivers of 61 youth with type 1 diabetes completed the Diabetes Injection Distress-Parent Report Form (DID-PRF); a subsample (n = 19; 30%) submitted video recordings of their children's insulin injections. RESULTS The DID-PRF demonstrated acceptable internal consistency and moderately correlated with video recordings. Half of parents (n = 31; 51%) reported their child's history of insulin injection distress; 30% reportedly experienced distress ≥1 year after diagnosis. Current distress was reported for about half (n = 28) of children. More parent and child coping/distress behaviors was associated with younger child age. Children displayed more injection distress in their first month after diagnosis versus the most recent month. CONCLUSIONS Diabetes-related injection distress and associated coping behaviors should be further explored; longitudinal data and additional measurement development is warranted.

Abstract
OBJECTIVE We aimed to establish the ideal injection techniques using 5-mm needles to reliably inject insulin into the subcutaneous fat in both children and adults and to quantify the associated pain and leakage of the test medium. RESEARCH DESIGN AND METHODS A total of 259 subjects (122 children/adolescents and 137 adults) were injected with sterile air corresponding to 20 IU insulin (200 microl) with 32-G 5-mm needles at 90 degrees or 45 degrees , in the abdomen and thigh, and with or without a pinched skin fold. Injection depth was assessed via ultrasonography. Subjects rated pain on a visual analog scale. Test medium injections into the abdomen and thigh (0.2-0.6 ml) were also administered to assess injection leakage. RESULTS Among children, 5.5% of injections were intramuscular (IM) and 0.5% were intradermal, while in adults, the incidence was 1.3 and 0.6%, respectively. The frequency of IM injections was greater in boys and negligible among adult women. Subcutaneous fat thickness was the primary predictor of the likelihood of IM injections (P < 0.001). A third of all patients reported experiencing no pain during insulin injection, with children/adolescents experiencing considerably more discomfort than adults. Some leakage of medium was observed, but was unrelated to injection volume and was generally minimal. CONCLUSIONS 5-mm needles are reliably inserted into subcutaneous fat in both adults and children. These needles were associated with reduced pain and minimal leakage. We recommend an angled injection with a pinched skin fold for children, while in adults, the technique should be left to patient preference.

Abstract
Large clinical trials have shown that improving glycaemic control significantly reduces the risk of long-term microvascular complications in type 1 (T1DM) and type 2 (T2DM) diabetes. Achieving optimal glycaemic control often requires the use of multiple daily insulin injections. Current approaches to insulin administration are less than optimal; many T2DM patients view insulin therapy as inconvenient and uncomfortable and may delay starting insulin therapy because of this. A new oral insulin spray formulation and delivery system provides an alternative to injectable and inhaled insulin. The system allows a liquid oral spray insulin formulation to be delivered into the mouth via an aerosolized spray. The oral insulin spray is a tasteless liquid aerosol mist formulation that is administered to the buccal mucosa using a proprietary delivery system. The active pharmaceutical ingredient is recombinant human insulin; however, the formulation behaves in a fashion more similar to the synthetic fast-acting insulin analogues. In clinical studies of healthy subjects and subjects with T1DM and T2DM, investigators have shown that the oral insulin spray was absorbed in direct relation to the amount given and had a faster onset and a shorter duration of action when compared with regular insulin given subcutaneously. In all of the studies conducted, the oral insulin spray was generally well tolerated. Some healthy individuals and subjects with T1DM experienced transient (1-2 min) mild dizziness during dosing; these symptoms were mild and self-limited. No changes in vital signs, laboratory values or physical examination results were noted. The ease of use of the insulin spray formulation may increase patient acceptance and treatment compliance, thereby potentially reducing complications and improving quality of life for patients with insulin-dependent diabetes. This article provides an overview of the safety profile and proposed mechanism of action of this insulin formulation and presents findings from trials which studied its effects in subjects with T1DM and T2DM.

Abstract
OBJECTIVE To determine if use of an injection port, the Insuflon, would help to improve glycemic control in youth with type 1 diabetes (TID) who were in suboptimal glycemic control (hemoglobin A1c, HbA1c >8.0%). STUDY DESIGN A three-arm randomized protocol was used to study the effects of the Insuflon (a subcutaneous injection port) vs. an alarmable blood glucose meter vs. a control group on glycemic control in 66 youth with T1D. All participants used insulin glargine as their basal insulin and the NovoPen Junior with insulin aspart as their rapid-acting insulin. Participants were randomized into control, alarm, or Insuflon groups. HbA1c levels were the primary outcome with values at baseline, 3, and 6 months. RESULTS Initial parameters were similar in the three groups. HbA1c values were significantly lower for youth who used the Insuflon than for the control group at 3 and 6 months (p = 0.025). The HbA1c values (in %) for youth using the Insuflon decreased significantly from 9.4 at screening to 8.7 at 3 months (p < 0.001) and 8.5 at 6 months (p < 0.001). There were no significant reductions (p > or = 0.05) in the HbA1c values within the other two groups. CONCLUSION The Insuflon injection port helps some youth with T1D to improve glycemic control.

Abstract
Inhaled insulin has attractive pharmacodynamic properties with a fast onset of action which should lead to improved postprandial blood glucose concentrations. Comparisons with regular subcutaneous (sc) insulin in clinical studies, however, showed lower fasting blood glucose concentrations. Overall, clinical efficacy of inhaled insulin was comparable to that of regular sc insulin. Treatment with inhaled insulin was safe and well tolerated, with slight and reversible changes in lung function parameters and a rise in insulin antibodies (not associated with any clinical or safety parameters) as main adverse effects. Treatment satisfaction in open-label studies was higher with inhaled than with sc insulin, indicating that inhaled insulin might help to overcome one of the major hurdles of diabetes therapy, i.e. a timely initiation of insulin therapy. The first inhaled insulin formulation was approved in the US and Europe in January 2006, but some countries granted reimbursement only for selected patients, or did not reimburse treatment with inhaled insulin at all because of the high treatment costs. These are due to the rather low bioavailability of approximately 8-15%. Therefore, further research is needed to improve the bioavailability of inhaled insulin: e.g. through optimization of the inhaler, the insulin formulation, or the inhalation technique. In view of the potential for further improvement, inhaled insulin may become a very attractive alternative to sc insulin, in particular in patients in whom insulin therapy has to be initiated and/or intensified.

Abstract
Stimulus fading in the form of gradually increased exposure to a fear-evoking stimulus, often combined with differential reinforcement, has been used to treat phobias in children who are otherwise normal and in children with autism. In this investigation, we applied stimulus fading plus differential reinforcement with an adolescent with autism and diabetes whose needle phobia had prevented medical monitoring of his blood glucose levels for over 2 years. Results showed that the treatment was successful in obtaining daily blood samples for measuring glucose levels.

Abstract
Intensive insulin treatment is defined by basal-prandial insulin therapy which tries to reproduce physiological insulin secretion. This requires 3 to 5 injections and self-monitoring of blood glucose 4 to 5 times a day. Patients who accept their disease and the demanding treatment regimen most often achieve HbA1(c) < 7.5%. Severe complications of diabetes can be avoided without increasing the risk of severe hypoglycemia. However, 50% of type 1 diabetic patients do not reach this objective. The reasons are: the disease itself, the diabetic patient, or the physician. Brittle diabetes with severe, repeated episodes of hypoglycemia and inversely persistent postprandial hyperglycemia prevents patients from reaching the ideal glycemic target. More often, the main obstacle is related to psychological problems: difficulties in self-regulation, denial of the disease, or phobia of hypoglycemia with avoidance behavior. Frequently, young women present eating disorders which can explain the poor diabetes control. The physician himself may be implicated in these poor glycemic results by not prescribing the right tools to obtain optimal glycemic control (staying with just two daily injections with premixed insulin) or by assigning glycemic targets inaccessible for the patient, or when an empathic relationship cannot be established between the patient and the physician. Patient empowerment is the key to the success of functional insulin treatment.

Abstract
BACKGROUND Oral insulin spray is a new, noninjectable method of insulin delivery. This system delivers an aerosol of uniform-sized droplets containing regular human insulin at a high velocity into the oropharyngeal cavity for local transmucosal absorption. OBJECTIVE The purpose of this study was to compare the pharmacokinetic and pharmacodynamic properties of single-dose oral insulin spray and SC insulin injection in healthy subjects. METHODS Healthy male volunteers aged 21 to 25 years participated in this open-label study conducted at the Diabetes Unit, Hadassah-Hebrew University Hospital, Jerusalem, Israel. Subjects presented at 2 visits separated by 7 to 14 days. At both visits, the euglycemic clamp technique was used to maintain a constant blood glucose level. At one visit, subjects received regular human insulin 0.1 U/kg by SC injection. At the other visit, subjects received 15 puffs (150 U) of oral insulin spray. The pharmacokinetic (insulin absorption) and pharmacodynamic (glucose uptake) properties of the drugs were evaluated using blood analyses over the subsequent 360 minutes. RESULTS Six volunteers were enrolled (mean [SD] age, 22.8 [1.2] years; mean [SD] body mass index, 23.2 [2.2] kg/m(2)). The mean (SD) baseline-corrected C(max) was significantly higher with oral insulin spray compared with SC insulin (54.0 [20.3] vs 30.8 [6.1] microU/mL; P = 0.028). Mean (SD) T(max) was significantly shorter with oral insulin spray compared with SC insulin (23.3 [5.2] vs 83.3 [42.2] minutes; P = 0.027). The mean (SD) time to maximal metabolic effect (maximum glucose infusion rate [GIR(max)]) (44.2 [8.6] vs 100.0 [35.6] minutes) and late time to half-maximal effect (101.0 [41.0] vs 257.2 [27.8] minutes) were shorter with oral insulin spray compared with SC insulin (both, P = 0.028). The baseline-corrected GIR(max) (6.8 [3.3] vs 6.2 [2.3] mg/kg . min) and glucose consumption (396.7 [178.0] vs 432.1 [226.0] mg/kg) during the 120 minutes after study drug administration were comparable between oral and SC insulin, respectively. CONCLUSIONS In this study in a small, selected population of healthy male subjects under euglycemic conditions, oral insulin spray was associated with a higher C(max), shorter T(max), and faster time to peak glucose uptake compared with SC insulin. The short T(max) and the 120-minute duration of effect of oral insulin spray suggest it may be a promising alternative for fulfilling meal-related insulin requirements in persons with diabetes.

Abstract
OBJECTIVE To examine psychological functioning and self-management behaviours of Dutch adult patients with insulin-requiring diabetes mellitus suffering from extreme fear of self-injecting (FSI) and/or fear of self-testing (FST). METHODS A cross-sectional survey was performed in a sample of insulin-treated diabetes patients (n=1275; 51.1% male; age 49.7+/-15.8 years; 58.0% Type 1 diabetes), assessing FSI and FST. Patients completed the questionnaires concerning trait/state anxiety, depression, fear of hypoglycemia, diabetes-related distress, diabetes self-care activities, and general well-being. Comparisons were made on these measures between patients with extremely high scores on FSI and/or FST (> or = 95th percentile) and the other patients. Patients with extreme scores on FSI and/or FST were invited to take part in a second survey to assess the prevalence of major depression, common fears/phobias, and psychoneuroticism. RESULTS People with extreme FSI/ FST scores, as compared to the other patients, reported higher levels of trait/state anxiety and depression. This group also reported more fear of hypoglycaemia and diabetes-related distress, had lower levels of general well-being, and reported less frequent self-monitoring of blood glucose. The second survey showed 11.1% of patients with extreme FSI/FST reporting scores indicating major depression. Prevalence of scores greater than or equal to the high scores on phobias (38.0-63.3%) and psychoneuroticism (27.8%) were consistently higher than norm group prevalences. DISCUSSION Extreme levels of FSI and/or FST are associated with high diabetes-related distress, poor general well-being, and psychological comorbidity, as well as poorer adherence to the diabetes treatment regimen. It is concluded that patients with extreme FSI/FST are often burdened with more than this specific phobia.

Abstract
AIMS To define clinically relevant cut-off points for severe fear of self-injecting (FSI) and self-testing (FST) (phobia) in insulin-treated patients with diabetes, and to estimate the magnitude of these phobias in our research population. METHODS FSI and FST were assessed in a cross-sectional survey using the Diabetes Fear of Injecting and Self-testing Questionnaire (D-FISQ). A sample of 24 insulin-treated adult diabetic patients was selected from the high-scorers on FSI and/or FST (> or = 95th percentile). FSI and FST were re-assessed, after which patients participated in a behavioural avoidance test (BAT), thereby determining the current level of avoidance of either self-injecting or self-testing. FSI and FST scores were linked to the outcome of the BATs. Cut-off scores for severe FSI/FST were determined and extrapolated to the total study population (n = 1275). RESULTS Seven patients participated in the self-injecting BAT: two patients refused to perform an extra injection. In the self-testing BAT (n = 17) four patients declined to perform the extra blood glucose self-test. Extrapolation of FSI and FST cut-off scores to the total research population showed that 0.2-1.3% of the population scored in the severe FSI range. In FST, 0.6-0.8% of the total study population obtained scores in the cut-off range. CONCLUSIONS Severe FSI and FST, characterized by emotional distress and avoidance behaviour, seems to occur in a small group of insulin-treated patients with diabetes. The D-FISQ can be of use to health care professionals (physicians, nurse specialists) in quickly providing valuable information on levels of FSI and FST in diabetes patients.

Abstract
OBJECTIVE The purpose of this study was twofold (i): to evaluate metabolic control in patients receiving CSII therapy in a routine pediatric diabetes clinic by describing reasons for initiating therapy and daily management issues, including needle fear; and (ii) to assess the change in parental involvement and anxiety once their child initiated CSII therapy. RESEARCH DESIGN AND METHODS The study included 52 subjects (aged 7.6-23.6 yr) from a general pediatric diabetes clinic. Management issues were defined as diet, exercise, home blood glucose monitoring (HBGM) frequency, and self/staff assessment of needle fear. Characteristics were analyzed both according to a 0.5% change in HbA1c status (decreased vs. stable vs. increased) compared with pre-CSII therapy, and final HbA1c achieved (< or = 8.1 vs. > 8.1%). RESULTS The primary recommendation source for CSII use was most often the physician/diabetes team (48.1%), followed by a combination of the former with a personal referral source (32.7%). The most common reason (71.2%) for CSII initiation was a combination of wanting to achieve better metabolic control, dislike of insulin injections, and/or increased flexibility in daily living. Over one-quarter (26.9%) of subjects were identified as being needle-fearful, and this characteristic was predictive of final metabolic control (3/25 subjects </= 8.1% vs. 11/27 subjects > 8.1%, p = 0.03). On CSII therapy, dietary carbohydrate consistency was highly variable, and most subjects (65.3%) exclusively used an insulin to carbohydrate ratio for insulin bolus dosage calculation. The most common adjustment strategy (63.5%) for exercise was a combination of decreasing the insulin basal rate, disconnecting the pump, and/or eating extra carbohydrates. For the total cohort, the frequency of HBGM significantly increased on CSII therapy (4.31-4.85 tests/day, p = 0.02). Females did not have a significant change in HBGM frequency, while the youngest subjects had the highest HBGM frequency. Parental involvement and anxiety primarily stayed the same or decreased, regardless of the child's age (< or = 18 vs. > 18 yr) or metabolic control. CONCLUSIONS Analyses of the various characteristics identified only needle fearfulness as being predictive of poor metabolic control. Interestingly, poor control with CSII therapy did not result in a significant increase in parental involvement and/or anxiety.

Abstract
Phobic disorders are more common in people with diabetes than in the general population. The management of phobic disorders in patients with diabetes, particularly when associated with a fear of hypoglycaemia, is especially challenging and requires close collaboration between psychological medicine and diabetes teams. Difficulty in distinguishing symptoms of anxiety from those of hypoglycaemia, and the real dangers associated with hypoglycaemia, complicate the delivery of psychological interventions that are used routinely in the treatment of phobias. Avoidance of hypoglycaemia can lead to deterioration in diabetes control. This case report describes a man with Type 1 diabetes who developed agoraphobia with panic disorder, associated with fear of hypoglycaemia and deterioration in glycaemic control. The management of patients with diabetes and phobic disorders, with particular reference to those associated with fear of hypoglycaemia, is discussed.

Abstract
AIMS Specialist diabetes clinics have an established role in prevention and management of complications. As psychological problems are usually treated separately from diabetes centres, the role of a specialist psychiatrist within a teaching hospital was assessed. The aims of the study were to describe referral patterns, specific psychiatric conditions and treatments offered. RESULTS During weekly outpatient sessions over a 12-month period, 31 patients were referred with a wide range of psychiatric diagnoses. One-third of patients were seen on the day and two-thirds within 2 weeks of referral. Treatments included anti-depressant medication, counselling and cognitive behaviour therapy. Successful discharge was obtained in 10 subjects and eight were undergoing continued treatment. CONCLUSIONS The range of specific diagnoses requiring psychiatric supervision supported the role of specifically trained personnel as seen in a joint liaison psychiatry-diabetes service.

Abstract
The presence of injection related anxiety and phobia may influence compliance, glycaemic control and quality of life in patients with insulin-treated diabetes. Unselected consecutive, insulin-treated patients attending a diabetes clinic for follow-up, completed a standardised questionnaire providing an injection anxiety score (IAS) and general anxiety score (GAS). A total of 115 insulin-treated (80 Type 1 and 35 Type 2) diabetic patients completed the questionnaire. Injections had been avoided secondary to anxiety in 14% of cases and 42% expressed concern at having to inject more frequently. An IAS > or = 3 was seen in 28% of patients and of these, 66% injected insulin one to two times/day, 45% had avoided injections, and 70% would be bothered by more frequent injections. A significant correlation between IAS and GAS was seen (Kendall's tau-a 0.30, 95% CI 0.19-0.41, P < 0.001). GAS was significantly associated with both previous injection avoidance and expressed concern at increased injection frequency. No significant correlation was seen with HbA1c and injection or general anxiety scores. Symptoms relating to insulin injection anxiety and phobia have a high prevalence in an unselected group of diabetic patients requiring insulin injections and are associated with higher levels of general anxiety.
