Abstract
Diabetes is unique among chronic diseases because clinical outcomes are intimately tied to how the person living with diabetes reacts to and implements treatment recommendations. It is further characterised by widespread social stigma, judgement and paternalism. This physical, social and psychological burden collectively influences self-management behaviours. It is widely recognised that the individual's perspective about the impact of trying to manage the disease and the burden that self-management confers must be addressed to achieve optimal health outcomes. Standardised, rigorous assessment of mental and behavioural health status, in interaction with physical health outcomes is crucial to aid understanding of person-reported outcomes (PROs). Whilst tempting to conceptualise PROs as an issue of perceived quality of life (QoL), in fact health-related QoL is multi-dimensional and covers indicators of physical or functional health status, psychological and social well-being. This complexity is illuminated by the large number of person reported outcome measures (PROMs) that have been developed across multiple psychosocial domains. Often measures are used inappropriately or because they have been used in the scientific literature rather than based on methodological or outcome assessment rigour. Given the broad nature of psychosocial functioning/mental health, it is important to broadly define PROs that are evaluated in the context of therapeutic interventions, real-life and observational studies. This report summarises the central themes and lessons derived in the assessment and use of PROMs amongst adults with diabetes. Effective assessment of PROMs routinely in clinical research is crucial to understanding the true impact of any intervention. Selecting appropriate measures, relevant to the specific factors of PROs important in the research study will provide valuable data alongside physical health data.

[PMID: 38736324 DOI: 10.1111/dme.15338] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 04/05/2024] [Accepted: 04/14/2024] [Indexed: 05/14/2024]
Abstract
BACKGROUND AND AIMS The use of diabetes technologies is increasing worldwide, with health systems facilitating improved access to devices. Continuous glucose monitoring is a complex intervention that provides information on glucose concentration, rate and direction of change, historical data and alerts and alarms for extremes of glucose. These data do not themselves change glycaemia and require translation to a meaningful action for impact. It is, therefore, crucial that such systems advance to better meet the needs of individuals using them. METHODS Narrative review of the use of, engagement with, limitations and unmet needs of continuous glucose monitoring systems. RESULTS CGM devices have made a significant contribution to the self-management of diabetes; however, challenges with access and user experience persist, with multiple limitations to uptake and benefit. These limitations include physical size and implementation, with associated stigma, alarm fatigue, sleep disturbance and the challenge of addressing large volumes of real-time data. Greater personalisation throughout the continuous glucose monitoring journey, with a focus on usability, may improve the benefits derived from the device and reduce the burden of self-management. Healthcare professionals may have unconscious biases that affect the provision of continuous glucose monitors due to deprivation, education, age, ethnicity and other characteristics. CONCLUSIONS Continuous glucose monitoring exerts a dose-dependent response; the more it is used, the more effective it is. For optimal use, continuous glucose monitors must not just reduce the burden of management in one dimension but facilitate net improvement in all domains of self-management for all users.

Abstract
BACKGROUND Compared with multiple daily insulin injections (MDI), continuous subcutaneous insulin infusion (CSII) is significantly more expensive and has not been widely used in Chinese type 1 diabetes mellitus (T1DM) patients. So there are still significant knowledge gaps regarding clinical and patient-reported outcomes in China. AIMS This study aims to compare the glycated hemoglobin (HbA1C), insulin therapy related quality of life (ITR-QOL), fear of hypoglycemia (FOH) of adult T1DM patients treated with MDI and CSII based on propensity score matching in real-world conditions in China. METHODS Four hundred twenty adult T1DM patients who were treated with MDI or CSII continuously for more than 12 months in a national metabolic center from June 2021 to June 2023 were selected as the study subjects. Their QOL and FOH were evaluated with Insulin Therapy Related Quality of Life Measure Questionnaire-Chinese version (ITR-QOL-CV) and the Chinese Version Hypoglycemia Fear Survey-Worry Scale (CHFSII-WS), and their HbA1C were collected at the same time. Potential confounding variables between the two groups were matched using propensity score matching. RESULTS Of the 420 patients included in the study, 315 were in MDI group and 105 were in CSII group. 102 pairs were successfully matched. After matching, the total score of ITR-QOL-CV scale in CSII group was significantly higher than that in MDI group (87.08 ± 13.53 vs. 80.66 ± 19.25, P = 0.006). Among them, the dimensions of daily life, social life, and psychological state were all statistically different (P < 0.05). The scores of CHFSII-WS (8.33 ± 3.49 vs. 11.77 ± 5.27, P = 0.003) and HbA1C (7.19 ± 1.33% vs. 7.71 ± 1.93%, P = 0.045) in CSII group were lower than those in MDI group. CONCLUSIONS 25.0% of T1DM adults are treated with CSII. Compared with adult T1DM patients treated with MDI, those treated with CSII have higher ITR-QOL, less FoH, and better control of HbA1C in real-world conditions in China. Therefore, regardless of economic factors, CSII is recommended for adult T1DM patients to optimize the therapeutic effect and outcomes.

Abstract
OBJECTIVE The purpose of this study was to test the preliminary effectiveness of a cognitive behavioral therapy intervention (Fear Reduction Efficacy Evaluation [FREE]) designed to reduce fear of hypoglycemia in young adults with type 1 diabetes. The primary outcome was fear of hypoglycemia, secondary outcomes were A1C, and glycemic variability. METHODS A randomized clinical trial was used to test an 8-week intervention (FREE) compared to an attention control (diabetes education) in 50 young adults with type 1 diabetes who experienced fear of hypoglycemia at baseline. All participants wore a continuous glucose monitor for the 8-week study period. Self-reported fear of hypoglycemia point-of-care A1C testing, continuous glucose monitor-derived glucose variability were measured at baseline, Week 8, and Week 12 (post-program). RESULTS Compared to controls, those participating in the FREE intervention experienced a reduction in fear of hypoglycemia (SMD B = -8.52, p = 0.021), change in A1C (SMD B = 0.04, p = 0.841) and glycemic variability (glucose standard deviation SMD B = -2.5, p = 0.545) by the end of the intervention. This represented an 8.52% greater reduction in fear of hypoglycemia. CONCLUSION A cognitive behavioral therapy intervention (FREE) resulted in improvements in fear of hypoglycemia.

Abstract
PURPOSE Hypoglycemia represents a significant source of anxiety for children with type 1 diabetes mellitus (T1DM) and their caretakers. Fear of hypoglycemia (FoH) was measured in children and adolescents with T1DM as well as in their parents using an established research instrument, the Hypoglycemia Fear Survey (HFS). METHODS This is a two-center, cross-sectional study involving 100 children and adolescents aged 6-18 years old diagnosed with T1DM. One parent of each child also participated in the study. The participants, who were recruited from two different pediatric endocrine outpatient clinics, were asked to complete the translated Greek version of the HFS, which includes one version for children (C-HFS) and one for parents (P-HFS). The association of the questionnaire responses with subjects' characteristics, such as current age, age at diagnosis, duration of diabetes, HbA1c levels, and mode of diabetes treatment were assessed. RESULTS Parents exhibited significantly higher mean HFS scores than their children. No significant correlation was found between the P-HFS or the C-HFS scores and the age of the children, duration of diabetes, HbA1c, or mode of treatment. CONCLUSION The finding that parents experience higher levels of FoH compared to their children emphasizes the importance of healthcare providers to screen parental FoH and focus on approaches to support them in order to reduce their psychological burden, thus optimizing children's diabetes management.

Abstract
BACKGROUND Managing glucose levels during exercise is challenging for individuals with type 1 diabetes (T1D) since multiple factors including activity type, duration, intensity and other factors must be considered. Current decision support tools lack personalized recommendations and fail to distinguish between aerobic and resistance exercise. We propose an exercise-aware decision support system (exDSS) that uses digital twins to deliver personalized recommendations to help people with T1D maintain safe glucose levels (70-180 mg/dL) and avoid low glucose (<70 mg/dL) during and after exercise. METHODS We evaluated exDSS using various exercise and meal scenarios recorded from a large, free-living study of aerobic and resistance exercise. The model inputs were heart rate, insulin, and meal data. Glucose responses were simulated during and after 30-minute exercise sessions (676 aerobic, 631 resistance) from 247 participants. Glucose outcomes were compared when participants followed exDSS recommendations, clinical guidelines, or did not modify behavior (no intervention). RESULTS exDSS significantly improved mean time in range for aerobic (80.2% to 92.3%, P < .0001) and resistance (72.3% to 87.3%, P < .0001) exercises compared with no intervention, and versus clinical guidelines (aerobic: 82.2%, P < .0001; resistance: 80.3%, P < .0001). exDSS reduced time spent in low glucose for both exercise types compared with no intervention (aerobic: 15.1% to 5.1%, P < .0001; resistance: 18.2% to 6.6%, P < .0001) and was comparable with following clinical guidelines (aerobic: 4.5%, resistance: 8.1%, P = N.S.). CONCLUSIONS The exDSS tool significantly improved glucose outcomes during and after exercise versus following clinical guidelines and no intervention providing motivation for clinical evaluation of the exDSS system.

Abstract
BACKGROUND Hypoglycemia is a frequent and acute complication in type 1 diabetes mellitus (T1DM) and is associated with a higher risk of car mishaps. Currently, hypoglycemia can be detected and signaled through flash glucose monitoring or continuous glucose monitoring devices, which require manual and visual interaction, thereby removing the focus of attention from the driving task. Hypoglycemia causes a decrease in attention, thereby challenging the safety of using such devices behind the wheel. Here, we present an investigation of a hands-free technology-a voice warning that can potentially be delivered via an in-vehicle voice assistant. OBJECTIVE This study aims to investigate the feasibility of an in-vehicle voice warning for hypoglycemia, evaluating both its effectiveness and user perception. METHODS We designed a voice warning and evaluated it in 3 studies. In all studies, participants received a voice warning while driving. Study 0 (n=10) assessed the feasibility of using a voice warning with healthy participants driving in a simulator. Study 1 (n=18) assessed the voice warning in participants with T1DM. Study 2 (n=20) assessed the voice warning in participants with T1DM undergoing hypoglycemia while driving in a real car. We measured participants' self-reported perception of the voice warning (with a user experience scale in study 0 and with acceptance, alliance, and trust scales in studies 1 and 2) and compliance behavior (whether they stopped the car and reaction time). In addition, we assessed technology affinity and collected the participants' verbal feedback. RESULTS Technology affinity was similar across studies and approximately 70% of the maximal value. Perception measure of the voice warning was approximately 62% to 78% in the simulated driving and 34% to 56% in real-world driving. Perception correlated with technology affinity on specific constructs (eg, Affinity for Technology Interaction score and intention to use, optimism and performance expectancy, behavioral intention, Session Alliance Inventory score, innovativeness and hedonic motivation, and negative correlations between discomfort and behavioral intention and discomfort and competence trust; all P<.05). Compliance was 100% in all studies, whereas reaction time was higher in study 1 (mean 23, SD 5.2 seconds) than in study 0 (mean 12.6, SD 5.7 seconds) and study 2 (mean 14.6, SD 4.3 seconds). Finally, verbal feedback showed that the participants preferred the voice warning to be less verbose and interactive. CONCLUSIONS This is the first study to investigate the feasibility of an in-vehicle voice warning for hypoglycemia. Drivers find such an implementation useful and effective in a simulated environment, but improvements are needed in the real-world driving context. This study is a kickoff for the use of in-vehicle voice assistants for digital health interventions.

Abstract
AIMS Although consistent data support the outpatient use of continuous glucose monitoring (CGM) to improve glycemic control and reduce hypoglycemic burden, and clinical outcomes, there are limited data regarding its use in the hospital setting, particularly in the non-intensive care unit (non-ICU) setting. The emerging use of CGM in the non-critical care setting may be useful in increasing the efficiency of hospital care and reducing the length of stay for patients with diabetes while improving glycemic control. DATA SYNTHESIS The purpose of this Expert Opinion paper was to evaluate the state of the art and provide a practical model of how CGM can be implemented in the hospital. SETTING A patient's CGM journey from admission to the ward to the application of the sensor, from patient education on the device during hospitalization until discharge of the patient to maintain remote control. CONCLUSIONS This practical approach for the implementation and management of CGM in patients with diabetes admitted to non-ICUs could guide hospitals in their diabetes management initiatives using CGM, helping to identify patients most likely to benefit and suggesting how this technology can be implemented to maximize clinical benefits.

Abstract
AIMS To examined the relationship between fear of hypoglycemia and certain variables in people with type 2 diabetes mellitus (T2DM) based on the Capability, Opportunity, Motivation, and Behavior model, combined with the context unique to people with diabetes to provide a basis for developing targeted nursing interventions. METHODS In this cross-sectional study, 212 people with T2DM were recruited from February 2021 to July 2021. Data were collected using the Hypoglycaemia Fear Survey, Gold score, Patient Assessment of Chronic Illness Care (PACIC) scale and Diabetic Self-Management Attitudes Scale. Multiple linear regression analysis was performed to determine the predictors of fear of hypoglycemia using SPSS 26.0. RESULTS The mean fear of hypoglycemia score was 74.88 ± 18.28 (range: 37.00-132.00). In people with T2DM, the frequency of blood glucose monitoring, the frequency of hypoglycemia in the past half-year, degree of understanding of hypoglycemia, impaired awareness of hypoglycemia, PACIC, and self-management attitude of diabetes were the influencing factors of fear of hypoglycemia (adjusted R2 = 0.560, F[21,190] = 13.800, P < 0.001). These variables explained 56.0% of the variance in the fear of hypoglycemia. CONCLUSIONS The level of fear of hypoglycemia in people with T2DM was relatively high. In addition to paying attention to the disease characteristics of people with T2DM, medical staff should also pay attention to patients' own perception and handling ability of disease and hypoglycemia, attitude toward self-management behavior and external environment support, all of which have a positive effect on improving the fear of hypoglycemia in people with T2DM, optimizing the self-management level and improving quality of life.

Relationship between depressive and anxiety symptoms and fear of hypoglycemia among adolescents and adults with type 1 diabetes mellitus. Prim Care Diabetes 2023; 17:255-259. [PMID: 36925404 DOI: 10.1016/j.pcd.2023.03.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 02/22/2023] [Accepted: 03/05/2023] [Indexed: 03/17/2023]
Abstract
BACKGROUND AND AIMS Emotional problems including anxiety, depression and fear of hypoglycemia (FOH) are common in patients with type 1 diabetes mellitus (T1DM). The aim of this study was to determine the prevalence of depressive and anxiety symptoms among patients with T1DM and their relation to glycemic control, diabetes complications and to FOH. METHODS This study included 325 patients with T1DM. Anxiety and depressive symptoms were assessed by Hospital Anxiety and Depression Scale (HADS) and FOH was assessed by Hypoglycemia Fear Survey II (HFS-II). Glycemic control was assessed by both fasting plasma glucose and HbA1c. A subsample of 75 patients was screened for diabetes complications. RESULTS The prevalence of anxiety symptoms, depressive symptoms and FOH was 76.3%, 61.8% and 20% respectively. Female sex was related to depressive symptoms but not to anxiety symptoms. Logistic regression analysis showed that both HbA1c and HFS-II total score were independently correlated with both anxiety symptoms and depressive symptoms. Age showed independent correlation with both HFS-II (total score) and with Hypoglycemia Fear Survey-worry (HFS-W) while HbA1c showed independent correlation with Hypoglycemia Fear Survey-behavior (HFS-B). Both anxiety and depressive symptoms were positively correlated to HFS-B score, HFS-W score and HFS-II total score. CONCLUSIONS FOH is not uncommon among Egyptian patients with T1DM and it seems to be one of the factors contributing to the increased prevalence of anxiety and depressive symptoms among those individuals. Addressing and managing the different psychological aspects of diabetes should be integrated within the routine diabetes care services for people with T1DM.

Abstract
Although a broad literature on fear of hypoglycemia and its impact on people with type 1 or type 2 diabetes has accumulated over the past three decades, there has been surprisingly little guidance concerning how best to tackle this problem in clinical care. The aim of this article is to begin filling this gap by describing the "hypoglycemic fear syndrome," which we define as hypoglycemic fear that has become so overwhelming that it leads to avoidance behaviors and chronically elevated glucose levels. We begin by presenting several illustrative cases, describing the syndrome and how it is most commonly presented in clinical care, and detailing its most common precipitants. We then offer practical, evidence-based strategies for clinical intervention, based on the literature and our clinical experience.

Abstract
OBJECTIVE The purpose of the present study was to investigate the fear of hypoglycemia (FoH) and its predictors among diabetic pregnant women. STUDY DESIGN Cross-sectional conducted between January to August 2022. METHODS In the present study, 250 diabetic pregnant women from Qazvin province participated. Demographic and fertility characteristics, FoH, adherence to treatment, self-efficacy, anxiety and depression were assessed. Data were analyzed using univariable and multivariable linear regression models. RESULTS The participants' mean age was 31.02 years (SD=4.72). The FoH mean score was 32.88 (out of 72). Based on the multivariable linear regression model, having a history of hypoglycemia (β = 0.44, p < 0.001), lower education (β = 0.17, p = 0.001), being treated with insulin (β = 0.22, p < 0.001), being treated with both insulin and diet (β = 0.16 p = 0.003), being of younger age (β = -0.13, p = 0.008), and depression (β = 0.16, p = 0.002) were independent predictors of FoH among pregnant women. CONCLUSION Diabetic pregnant women experience FoH, particularly those with a history of hypoglycemia. Therefore, providing education and counseling concerning hypoglycemia, complications, and necessary measures for this group of diabetic pregnant women are needed along with those who are younger, less educated, and have comorbid mental health conditions.

Abstract
Basal insulin (BI) is the main therapeutic option for patients with type 2 diabetes (T2D) who have not reached glycemic targets on oral antidiabetic drugs and/or glucagon-like peptide-1 receptor agonists. The results of epidemiological studies indicate that the majority of patients with T2D do not achieve the targeted parameters of glycemic control on BI in the real-world settings. In this review the results of real-world evidence studies assessing predictors of success or failure of BI therapy in patients with T2D are we summarized. A number of studies have demonstrated that delayed initiation of insulin therapy with a high level of glycated hemoglobin A1c (HbA1c) at the start of the treatment reduces achieving glycemic control targets on BI. Hypoglycemia in the first weeks or months of BI treatment may reduce the adherence and persistence to treatment and likelihood of achieving treatment targets. In real-world evidence studies, glargine 300 U/mL and degludec, the long-acting second-generation insulin analogues, have shown greater potential in reduction of HbA1c levels with a lower risk of hypoglycaemia compared to other BIs. In the DUNE, ATOS, and some others studies, a lack of insulin dose titration in newly initiated BI users and those who needed treatment intensification was demonstrated. Poor treatment adherence and persistence (missed injections, incorrect dose selection, and temporary or permanent discontinuation of insulin therapy), deviations in insulin injection technique, and formation of lipohypertrophy at the injection sites are also common problems that prevent good glycemic control in these patients. Therefore, patient education with a focus on injection technique, dose titration and prevention of hypoglycemia, as well as the use of the second-generation BI analogs, increases the chances for achieving glycemic control targets in patients with T2D who initiate or need to intensify BI therapy.

Abstract
Purpose The current study aimed to explore the potential effect of diabetes-related distress on the association between fear of hypoglycaemia and poor glycaemic control. We evaluated the specific aspects of fear of hypoglycaemia that affect glycaemic control among Saudi patients with type 2 diabetes (T2D). Methods Descriptive cross-sectional survey of patients with T2D attending a specialist diabetes clinic in Taif, Saudi Arabia. We used the Hypoglycaemia Attitudes and Behaviour Scale (HABS) for assessing fear of hypoglycaemia among our sample. We used Structural Equation Modelling to evaluate the moderators and correlates of fear of hypoglycaemia. Results We surveyed 365 patients with T2D. Cronbach's alpha for the HABS assessment was 0.84, an indication of excellent internal consistency. The composite reliability for hypoglycaemic anxiety was 86.8%; hypoglycaemic avoidance was 85.2%; and hypoglycaemic confidence was 92.6%. The mean HABS score was 32.7 points (out of 70 points; SD = 9.8 points). Fear of hypoglycaemia was associated with increased levels of glycated haemoglobin (HbA1c), presence of eye disease, heart disease, and stroke. Fear of hypoglycaemia was associated with poor glycaemic control. No significant moderating effect of diabetes-related distress was observed. However, only hypoglycaemic anxiety and avoidance were associated with poor glycaemic control. Confidence in the ability to control low glucose levels was not associated with elevated HbA1c levels. Conclusion A significant finding of this study highlighted the considerable and direct effect of fear of hypoglycaemia on poor glycaemic control among patients with T2D. However, only fear-related anxiety and avoidance-and not confidence in the ability to control low glucose levels-had an effect on poor glycaemic control.

Abstract
The present cross-sectional survey was performed to assess the prevalence and factors associated with fear of hypoglycemia (FoH) in hospitalized patients with type 2 diabetes (T2D). Between July and December 2020, 494 patients with T2D were evaluated via structured questionnaires containing sociodemographic information, clinical information, and the Fear of Hypoglycemia-15 scale (FH-15). Patients were divided into the FoH and non-FoH groups according to the FH-15 score. Univariate and multivariate logistic regression analyses were performed to determine factors associated with FoH. Variables with P values < 0.1 in the univariate model were included in the multivariate model. In this study, the prevalence of FoH was 17.4% (86/494). 247 (50.0%) patients experienced hypoglycemic episodes in the past year, and 15 (3.0%) patients experienced severe hypoglycemic episodes in the past year. The mean age was 60.04 ± 11.71 years old, and female patients accounted for 39.9% of the sample. The item with the highest average FH-15 scores was: how often are you afraid of having hypoglycemia while alone? Multivariate logistic regression analysis indicated that living alone (OR 2.48; 95% CI 1.20-5.14; P = 0.015), number of hypoglycemic episodes in the past year (OR 1.06; 95% CI 1.03-1.10; P < 0.001), number of severe hypoglycemic episodes in the past year (OR 2.61; 95% CI 1.20-5.69; P = 0.016), and duration of insulin use (OR 1.06; 95% CI 1.02-1.10; P = 0.006) were associated with FoH. The prevalence of FoH in hospitalized patients with T2D was high. FoH was associated with living alone, number of hypoglycemic episodes in the past year, number of severe hypoglycemic episodes in the past year, and duration of insulin use. These findings can contribute to early decision-making for preventing, identifying, and improving FoH in patients with T2D. In the future, interventions aimed at reducing FoH to improve the harmful effects of FoH are necessary, such as increasing diabetes-related knowledge and skills, increasing social support, reducing psychological fear, and minimizing risks for hypoglycemic episodes.

Abstract
INTRODUCTION Fear of hypoglycemia (FOH) is a phenomenon that affects people with diabetes experiencing hypoglycemia. On the one hand, FOH is an adaptive mechanism that helps to protect patients from hypoglycemia and its consequences. On the other hand, the non-normative level of FOH causes anxiety and tension, disturbs normal functioning, and makes normoglycemia maintenance difficult. OBJECTIVE The main objective of this review was to describe factors influencing FOH and methods of measurement of FOH levels. Moreover, we highlighted the impact of the new technologies used in diabetes therapy on FOH and different therapeutic possibilities helping patients cope with excessive levels of FOH. We also presented clinical cases of patients with high FOH levels met in clinical practice and discussed methods to better diagnose and assist people with this kind of problem. METHODS We searched for studies and articles via PubMed using the keywords fear of hypoglycemia, diabetes, and hypoglycemia. From screened documents identified from literature search, 67 articles were included in our review. RESULTS We divided results from literature screening into five parts: fear of hypoglycemia and hypoglycemia definition, risk factors for the FOH, methods of measuring levels of FOH, therapies for the FOH, and modern technologies. We also described clinical examples of abnormal fear of hypoglycemia in patients. CONCLUSION The review highlights the importance of taking into consideration fear of hypoglycemia phenomenon in diabetic patients in everyday clinical practice.

Abstract
This study aimed to reveal the relationship between quality of life (QOL) and sleep quality in patients with type 1 diabetes mellitus (T1DM). Overall, 202 patients with T1DM were registered in our study, and 192 were eligible for analysis. Baseline characteristics and laboratory values were determined. Patients completed the Japanese versions of the Pittsburgh Sleep Quality Index (PSQI) and Diabetes Therapy-Related QOL (DTR-QOL) questionnaires. We investigated the relationship between the global PSQI and DTR-QOL total scores by using linear regression analysis. In univariate regression analysis, DTR-QOL total scores were associated with body mass index, alcohol consumption, hypertension, hemoglobin A1c (HbA1c), and global PSQI score (all p-value <0.05) but not with sleep duration. When the association between PSQI subscales and DTR-QOL total scores was examined, DTR-QOL total scores were significantly related to subjective sleep quality and daytime dysfunction. In a multivariate regression analysis, the global PSQI score was negatively related to DTR-QOL total scores. Patients with an HbA1c concentration ≥8.0% had significantly lower DTR-QOL total scores. We revealed a relationship between QOL and sleep quality in T1DM patients and showed that the relationship between QOL and PSQI subscales in T1DM patients may be different from that in patients with type 2 diabetes mellitus. Assessing and managing sleep quality may be necessary for patients with diabetes to improve QOL.

Abstract
OBJECTIVE This study investigates the risk factors for severe hypoglycemia among Southeast Asian T2DM patients. METHODS Insulin-treated T2DM patients greater than 65 years old with HbA1c < 8% were recruited. They completed questionnaires detailing their experience of hypoglycemia and presence of impaired hypoglycemia awareness (IAH). Data on insulin treatment regimens, glycated haemoglobin (Hba1c) and comorbidities were also collected. RESULTS Of the 92 participants, 15.2% had at least one episode of severe hypoglycemia over the past year. Comparison between both groups showed that patients with severe hypoglycemia had lower Hba1c, higher Gold score (3.9 ± 1.9 vs. 2.5 ± 1.4; p < .05) and higher Hypoglycemia Fear Survey (HFS) worry score (39.1 ± 14.3 vs. 31.8 ± 11.8; p < .05). There were no significant differences in duration of diabetes and insulin treatment, treatment regimens and diabetes associated comorbidities except peripheral vascular disease. Furthermore, no significant differences were noted in HFS behavior score, hypoglycemia risk modifying behavior and social economic status. CONCLUSIONS Patients with severe hypoglycemia had tighter glycemic control, greater IAH and higher worry scores regardless of treatment regimens. Clinicians may play a significant role in tightening glycemic control and influencing the risk of severe hypoglycemia. Standard structured diabetes education may help reduce the risk of severe hypoglycemia among this group of patients.

Abstract
BACKGROUND Frequent scanning of intermittently scanned continuous glucose monitoring (isCGM) devices is associated with improvements in glycemic indices. Limited data is available for its correlation with fear of hypoglycemia (FOH), an established factor affecting quality of life and glycemic control in type 1 diabetes (T1DM). AIM The aim of the study was to analyze the association of sensor scanning frequency with FOH and glycemic indices in T1DM patients using isCGM. SUBJECTS AND METHODS T1DM patients using isCGM were eligible. Clinical data and Ambulatory Glucose Profile (AGP) reports were obtained from medical records. At outpatient visits, AGP of last 14 days prior to visit were analyzed and FOH was assessed using Hypoglycemia Fear Survey II (HFS II). RESULTS We included 77 consecutive T1DM patients (58 females, 19 males). Mean age was 34.1 ± 10.2 years and mean T1DM duration was 14.7 ± 12.0 years. Baseline mean glycemic indices were as follows: mean glucose - 155.8 ± 29.8 mg/dL; GMI - 53.3 ± 7.5 mmol/mol; TIR - 66.4 ± 17.8%; TBR70 - 4.5 ± 4.1%; TBR54 - 0.6 ± 1.2%; TAR180 - 29.2 ± 17.9%; TAR250 - 9.6 ± 10.4%; %CV - 36.7 ± 8.3. Average scanning frequency was 13.8 ± 7.8 scans/day. Mean HFS II scores were 16.1 ± 7.2 and 18.7 ± 12.2 in behavior and worry subscale, respectively. Correlation was confirmed between scanning frequency and mean glucose, GMI, TIR, TBR70, TAR180, TAR250, %CV and HFS II total, and HFS II - B (p<0.05 for all statistics). CONCLUSIONS For the first time, we report that higher scanning frequency is associated not only with better glycemic indices but also with less FOH in T1DM adult patients using isCGM.

Abstract
To investigate the fear of hypoglycaemia in patients with type 2 diabetes mellitus (T2DM), to identify factors related to this fear, and thus to provide evidence for clinical assessment. A total of 385 patients with T2DM who were admitted to the departments of endocrinology in five tertiary grade-A hospitals in Chongqing, China were included in this study. A questionnaire for general information and a Chinese version of Hypoglycemia Fear Survey (HFS) were used to collect the data. The average total score on the HFS was 71.67 ± 17.06 (HFS-W was 38.15 ± 10.57; HFS-B was 33.52 ± 9.54).The three items with the highest average score for HFS-W were not recognising low blood glucose (BG), not having food available, experiencing a hypoglycaemic episode alone, and for HFS-B were eating large amount of snacks, measuring BG six or more times per day, and keeping BG > 150 mmol/L. Regressions showed that number of hospitalisations for T2DM, receiving health education on diabetes, age and hypoglycaemia history because of T2DM were associated with fear of hypoglycaemia (all p < 0.05). Fear of hypoglycaemia in hospitalised patients with T2DM was strongly associated with diabetes health education, hospitalisation for diabetes, age, and hypoglycaemia history. Medical professionals should attach importance to the specific psychological interventions, health education on diabetes and the early prevention of hypoglycaemia or diabetic complications for patients with T2DM to reduce the fear of hypoglycaemia and improve their health status.

Abstract
Hypoglycaemia is a common barrier to optimal glycaemic management and often feared among adults with type 1 diabetes. The aim of this systematic review was to summarize current evidence regarding the impact of hypoglycaemia on quality of life (QoL) and related outcomes. Electronic searches of MEDLINE, PsycINFO, CINAHL, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials were conducted. Peer-reviewed empirical studies investigating the relationship between hypoglycaemia and QoL were eligible for inclusion. Thirty studies met the inclusion criteria. Extracted data was summarized in a narrative synthesis according to Synthesis Without Meta-Analysis guidelines. None of the studies examined the impact of hypoglycaemia on general QoL. There was no association between hypoglycaemia and diabetes-specific QoL in four of the 30 studies. Severe hypoglycaemia was associated with greater fear of hypoglycaemia and diabetes distress, and lower general emotional well-being, but not with depression, anxiety, or health status. Self-treated hypoglycaemia was associated with greater fear of hypoglycaemia. With the exception of fear of hypoglycaemia, this review shows mixed associations between hypoglycaemia and psychological outcomes. Further research is needed to investigate the impact of hypoglycaemia on other domains of QoL.

The MiaoMiao study: can do-it-yourself continuous glucose monitoring technology improve fear of hypoglycaemia in parents of children affected by type 1 diabetes? J Diabetes Metab Disord 2021; 19:1647-1658.

Abstract
Purpose Type 1 diabetes (T1D) is one of the most common chronic diseases of childhood and comes with considerable management and psychological burden for children and their families. Fear of hypoglycaemia (FOH), particularly nocturnal hypoglycaemia, is a common worry. Continuous glucose monitoring (CGM) is a tool that may help reduce FOH, as well as reduce overall diabetes burden. However, CGM systems are expensive and often not publicly funded or subsidised. MiaoMiao (MM) is a novel relatively affordable third-party add-on technology to intermittently scanned CGM (isCGM). MM allows users to convert their isCGM to a form of "Do-it-yourself" (DIY)-CGM. Our hypothesis is that MM-CGM will result in significant reduction in parental fear from hypoglycaemia. The primary objective is to determine the impact of real-time DIY-CGM on parental fear of hypoglycaemia using Hypoglycaemia Fear Survey (HFS). Methods This is a multisite randomised cross-over study of 55 New Zealand children (ages 2-13 years) with established T1D and current users of isCGM (Abbott FreeStyle Libre). DIY-CGM will be compared to usual care with isCGM. Participants will be randomised to either arm of the study for 6 weeks followed by a 4-week wash-out period before crossing over to the other study arm for a further 6 weeks. Discussion The results of this study will provide much needed clinical trial data regarding DIY-CGM effectiveness in reducing parental FOH, as measured by HFS, as well as various other secondary outcomes including traditional glycaemic metrics, and child and caregiver sleep. The trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN 12619001551189) on 18 November 2019, and the World Health Organisation International Clinical Trial Registry Platform (Universal Trial Number U1111-1236-9189).

Abstract
INTRODUCTION The aim was to determine the long-term cost-effectiveness of the Dexcom G6 real-time continuous glucose monitoring (RT-CGM) system versus self-monitoring of blood glucose (SMBG) in adults with type 1 diabetes (T1D) in France. METHODS The analysis was performed using the IQVIA Core Diabetes Model and utilized clinical input data from the DIAMOND clinical trial in adults with T1D. Simulated patients were assumed to have a mean baseline HbA1c of 8.6%, and those in the RT-CGM arm were assumed to have a HbA1c reduction of 1.0% compared with 0.4% in the SMBG arm. A quality of life (QoL) benefit associated with a reduced fear of hypoglycemia (FoH) and elimination of the requirement for fingerstick testing in the RT-CGM arm was also applied. RESULTS The G6 RT-CGM system was associated with an incremental gain in quality-adjusted life expectancy of 1.38 quality-adjusted life years (QALYs) compared with SMBG (10.64 QALYs versus 9.23 QALYs). Total mean lifetime costs were 21,087 euros higher with RT-CGM (148,077 euros versus 126,990 euros), resulting in an incremental cost-effectiveness ratio of 15,285 euros per QALY gained. CONCLUSIONS In France, based on a willingness-to-pay threshold of 50,000 euros per QALY gained, the use of the G6 RT-CGM system is cost-effective relative to SMBG for adults with long-standing T1D, driven primarily by improved glycemic control and the QoL benefit associated with reduced FoH and elimination of the requirement for fingerstick testing.

Abstract
Background: Despite new glucose sensing technologies, nocturnal hypoglycemia is still a problem for people with type 1 diabetes (T1D) as symptoms and sensor alarms may not be detected while sleeping. Accurately predicting nocturnal hypoglycemia before sleep may help minimize nighttime hypoglycemia. Methods: A support vector regression (SVR) model was trained to predict, before bedtime, the overnight minimum glucose and overnight nocturnal hypoglycemia for people with T1D. The algorithm was trained on continuous glucose measurements and insulin data collected from 124 people (22,804 valid nights of data) with T1D. The minimum glucose threshold for announcing nocturnal hypoglycemia risk was derived by applying a decision theoretic criterion to maximize expected net benefit. Accuracy was evaluated on a validation set from 10 people with T1D during a 4-week trial under free-living sensor-augmented insulin-pump therapy. The primary outcome measures were sensitivity and specificity of prediction, the correlation between predicted and actual minimum nocturnal glucose, and root-mean-square error. The impact of using the algorithm to prevent nocturnal hypoglycemia is shown in-silico. Results: The algorithm predicted 94.1% of nocturnal hypoglycemia events (<3.9 mmol/L, 95% confidence interval [CI], 71.3-99.9) with an area under the receiver operating characteristic curve of 0.86 (95% CI, 0.75-0.98). Correlation between actual and predicted minimum glucose was high (R = 0.71, P < 0.001). In-silico simulations showed that the algorithm could reduce nocturnal hypoglycemia by 77.0% (P = 0.006) without impacting time in target range (3.9-10 mmol/L). Conclusion: An SVR model trained on a big data set and optimized using decision theoretic criterion can accurately predict at bedtime if overnight nocturnal hypoglycemia will occur and may help reduce nocturnal hypoglycemia.

Abstract
AIMS AND OBJECTIVES To summarize and thematize fear of hypoglycemia (FOH) in individuals with type 1 diabetes (T1D) and type 2 diabetes (T2D) to provide a theoretical basis for the development of effective interventions. BACKGROUND FOH is common in this population and can reduce quality of life(QOL) and adversely impact upon diabetes self-care management. DESIGN a systematic review METHODS: Articles published between 2000 and 2019 were searched in PubMed, MEDLINE, EMBASE, Web of Science and three Chinese databases (CNKI, Wan-fang data and VIP). Eligible articles were selected using the Preferred Reporting Item for Systematic Review and Meta-analysis (PRISMA) guidelines. The quality of all articles finally included was evaluated by the Joanna Briggs Institute (JBI) Critical Appraisal tools. RESULTS Eighteen studies from 8654 papers were included. The sample size of each study ranged from 48 to 3812 subjects. FOH negatively impacted QOL, particularly psychosocial functioning, daily life and sleep quality. CONCLUSIONS FOH is a common and serious problem for patients, leading to poor QOL. It has been suggested that psychological concerns, QOL and effective countermeasures in individuals with T1D and T2D should be taken seriously. Advanced technology should be evaluated for its benefits before being used by patients. RELEVANCE TO CLINICAL PRACTICE The review highlights that FOH negatively impacts QOL, including psychosocial factors, daily life and sleep quality. Healthcare providers should develop targeted and professional assessment tools for FOH and QOL for patients with T2D, especially for patients who are about 60 years old. Advanced technology should be evaluated for its benefits before being used by patients.

Abstract
Background: Fear of hypoglycemia is an important problem in individuals with diabetes and could produce a negative impact on blood glucose control and quality of life in individuals with type 1 diabetes. Aim: To analyze (1) the associations among resilience, diabetes-related quality of life, and anxiety and depression in patients with type 1 diabetes with fear of hypoglycemia and (2) whether anxiety and depression mediate the relationship between resilience and quality of life. Design: A non-experimental, descriptive correlational design was used. Methods: Participants were 30 patients with type 1 diabetes with fear of hypoglycemia. Data were collected using several questionnaires administered between September 2019 and March 2020. Results: Resilience played a significant role in the anxiety and depression that accompanies diabetes. Mediation analysis was performed to assess whether the association between resilience and quality of life was mediated by anxiety and depression in series. The results show that the effect of resilience was mainly mediated by anxiety but not by depression. Conclusions: This study provides further evidence that high resilience could be a protective factor against the development of psychological symptomatology, which has a high prevalence in chronic conditions such as diabetes and can improve quality of life. Impact: Our study addresses the relationship between the positive psychological characteristic of resilience and anxiety, depression, and quality of life and the association between these variables. The results indicate that resilience has a positive impact on quality of life in people with type 1 diabetes who experience fear of hypoglycemia. Moreover, health professionals who provide care to these individuals should consider implementing programs to build resilience.

Abstract
OBJECTIVES Fear of hypoglycaemia (FoH) has been associated with suboptimal diabetes management and health outcomes. This study investigated factors associated with behavioural and emotional aspects of FoH among adults living with type 1 diabetes (T1D) mellitus. DESIGN Cross-sectional study. SETTING Online survey hosted on T1D Exchange Glu, an online community for patients living with T1D mellitus. MEASURES The Hypoglycaemia Fear Survey II-short form and the Hypoglycaemic Attitudes and Behaviour Scale were used to assess FoH. Multivariable regressions were performed on assessment scores. RESULTS The study included 494 participants (mean±SD age 43.9±12.2 years, duration of T1D mellitus 16.6±16.8 years, self-reported glycosylated hemoglobin (HbA1c) 6.9%±0.8% (52±9 mmol/mol)), 63% men, 89% on insulin pump, 25% experienced a severe hypoglycaemic event in the last 6 months. Multivariable regression analyses showed higher anxiety, depression severity and diabetes distress were independently associated with FoH (all p<0.01). Longer diabetes duration was associated with lower FoH (p<0.01). Past experience with severe hypoglycaemia was associated with higher worry of hypoglycaemia (p<0.01) but not avoidance behaviour (ns). CONCLUSIONS These results highlighted the multifaceted nature of FoH, which warrants further discussion between providers and patients to uncover drivers of and actions required to reduce FoH and improve patient care and outcomes.

Abstract
PURPOSE OF REVIEW Due to treatment advancements, individuals with type 1 diabetes (T1D) are living longer, presenting a unique understudied population with advanced complex needs. This article is a review of the aging literature in T1D and identifies existing gaps while serving as a call to the research community. RECENT FINDINGS Recent studies have identified an association between cognitive impairment and glycemic variability, as well as increased risk and frequency of hypoglycemia in older adults with T1D. However, limited research exists about additional physical and mental health conditions and barrier to successful treatment in this population. Older adults may experience both age- and diabetes-related barriers to diabetes management. Due to the scarcity of aging T1D research, current treatment guidelines for this age group are based on type 2 diabetes research. There is a critical need to further investigate the physical and mental effects of T1D and aging as well as public health policy; insurance challenges; and needs for support and interventions for older adults with T1D.

Abstract
Almost 100 years since the discovery of insulin, hypoglycaemia remains a barrier for people with type 1 diabetes to achieve and maintain blood glucose at levels which prevent long-term diabetes-related complications. Although hypoglycaemia is primarily attributable to the limitations of current treatment and defective hormonal counter-regulation in type 1 diabetes, the central role of psycho-behavioural factors in preventing, recognizing and treating hypoglycaemia has been acknowledged since the early 1980s. Over the past 25 years, as documented in the present review, there has been a substantial increase in psycho-behavioural research focused on understanding the experience and impact of hypoglycaemia. The significant contributions have been in understanding the impact of hypoglycaemia on a person's emotional well-being and aspects of life (e.g. sleep, driving, work/social life), identifying modifiable psychological and behavioural risk factors, as well as in developing psycho-behavioural interventions to prevent and better manage (severe) hypoglycaemia. The impact of hypoglycaemia on family members has also been confirmed. Structured diabetes education programmes and psycho-behavioural interventions with a focus on hypoglycaemia have both been shown to be effective in addressing problematic hypoglycaemia. However, the findings have also revealed the complexity of the problem and the need for a personalized approach, taking into account the individual's knowledge of, and emotional/behavioural reactions to hypoglycaemia. Evidence is emerging that people with persistent and recurrent severe hypoglycaemia, characterized by deeply entrenched cognitions and lack of concern around hypoglycaemia, can benefit from tailored cognitive behavioural therapy.

Abstract
BACKGROUND In persons with type 1 diabetes (T1D), hypoglycemia is the major limiting factor in achieving optimal glycemic control. All persons with T1D are at risk for hypoglycemia (blood glucose level < 70 mg/dl), which is life-threatening and accompanied by serious physical and psychological symptoms, resulting in profound fear of hypoglycemia (FOH) and reduced quality of life. Young adults with T1D are at risk for FOH and have worse glycemic control and self-management behavior than other age groups with T1D. FOH also results in increased glycemic variability (GV). A major gap exists in how to manage FOH. Our overall objective is to reduce FOH and improve diabetes self-management, glycemic control, and GV in young adults with T1D to reduce or delay diabetes complications and improve quality of life. We aim to (1) determine the feasibility and acceptability of an eight-week cognitive behavioral therapy (CBT)-based Fear Reduction Efficacy Evaluation (FREE) intervention in young adults with T1D who experience FOH; and (2) determine the impact of the FREE intervention, compared to an attention control group, on the outcomes FOH, self-management, glycemic control (A1C), and glycemic variability (continuous glucose monitoring recordings). METHODS/DESIGN A randomized controlled trial in 50 young adults aged 18 to 35 years with T1D will be used. Eligible subjects will be randomized to the intervention program (Fear Reduction Efficacy Evaluation [FREE]) or attention control group. A one-week run-in phase is planned, with baseline measures of FOH, self-management behavior, A1C, and real-time continuous glucose monitoring recordings (RT-CGM) to calculate GV for both groups. The intervention group will participate in eight weekly individual one-hour sessions using CBT and exposure treatment for specific fears. RT-CGM and a daily FOH diary will be used as feedback cues as part of the FREE program. The attention control group will participate in eight weekly individual one-hour diabetes self-management education (DSME) sessions and wear a RT-CGM device (to measure GV only) over 8 weeks. At completion, FOH will be measured, and RT-CGM recordings will be analyzed to determine differences between the FREE and control groups. DISCUSSION Findings from this proposed pilot study will serve as the foundation for a larger trial to reduce FOH and improve self-management, glycemic control, and GV.

Abstract
BACKGROUND The majority of therapies have generally targeted fasting glucose control, and current mealtime insulin therapies have longer time action profiles than that of endogenously secreted insulin. The primary purpose of this study was to assess both glucose time-in-range (TIR: 70-180 mg/dL) and postprandial glucose excursions (PPGE) in 1-4 h using a real-time continuous glucose monitor (CGM) with Technosphere insulin (TI) versus insulin aspart in patients with type 1 diabetes (T1DM) on multiple daily injections (MDI). RESEARCH DESIGN AND METHODS This pilot, investigator-led, collaborative, open-label, multicenter, clinical research trial enrolled 60 patients with T1DM with HbA1c levels ≥6.5% and ≤10%. Individuals were randomized to treatment with titrated TI (n = 26) or titrated insulin aspart (n = 34), stratified by baseline HbA1c levels (≤8% or >8%). All were required to wear a real-time CGM throughout the trial. All patients in the TI group were advised to take supplemental inhalations at 1 and 2 h after meals if indicated based on postprandial glucose (PPG) values. The coprimary outcomes were assessed both in the full intent-to-treat population and in those individuals randomized to TI who were compliant with supplemental doses ≥90% of the time (n = 15). The CGM data were analyzed using linear regression models. RESULTS Overall, those treated with TI versus aspart achieved comparable TIR, but less time spent in hypoglycemia (<60 and <50 mg/dL, both P < 0.05). In the TI-compliant group (n = 15), TIR was significantly greater (62.5% ± 2.6% vs. 53.8% ± 1.7%, P = 0.009) and time in hyperglycemia >180 mg/dL was lower (34.2% ± 2.7% vs. 41.0% ± 1.7%, P = 0.045) as compared with the aspart group. PPG was also significantly lower in the TI cohort at 60 and 90 min postmeal, and PPGE were lower in the TI-compliant group as compared with the aspart group over 1-4-h postmeal (P < 0.05). In addition, there was weight gain in the aspart group compared with weight loss in the TI group (P = 0.006) despite higher prandial TI insulin dose. CONCLUSIONS We conclude that using TI appropriately at mealtimes with supplemental dosing improves prandial glucose (TIR and 1-4 h) control without any increase in time in hypoglycemia or weight gain in patients with T1DM on MDI. The study results support a larger study using a treat-to-target design to confirm these findings. Clinical trial reg. no. NCT03143816, clinicaltrials.gov .

Abstract
Little is known regarding how hypoglycemia and associated fears influence day-to-day life among adults with type 1 diabetes (T1DM) who use contemporary diabetes management strategies. To address this gap, we performed an exploratory qualitative study with five focus groups of 30 people aged 20 to 57 years with T1DM. Sessions were audiotaped and transcribed, and then analyzed. Eight themes emerged: (a) hypoglycemic worry, (b) unpredictability and loss of control, (c) contending with life stress, (d) exercise benefits and challenges, (e) a changed relationship with food, (f) sleep fears, (g) a love/hate relationship with technology, and (h) coping strategies to make it better. Fear of hypoglycemia, diabetes management, and work demands confer a high degree of stress. Challenges surround food, exercise, and sleep. Technology is important but does not relieve fear of hypoglycemia. Developing strong coping skills and creating a safety net of support are necessary.

Abstract
OBJECTIVE Attaining glycemic targets without severe hypoglycemic events (SHEs) is a challenging treatment goal for patients with type 1 diabetes complicated by impaired awareness of hypoglycemia (IAH). The CIT Consortium Protocol 07 (CIT-07) trial showed islet transplantation to be an effective treatment for subjects with IAH and intractable SHEs. We evaluated health-related quality of life (HRQOL), functional health status, and health utility before and after pancreatic islet transplantation in CIT-07 trial participants. RESEARCH DESIGN AND METHODS Four surveys, the Diabetes Distress Scale (DDS), the Hypoglycemic Fear Survey (HFS), the Short Form 36 Health Survey (SF-36), and the EuroQoL 5 Dimensions (EQ-5D), were administered repeatedly before and after islet transplantation. Summary statistics and longitudinal modeling were used to describe changes in survey scores from baseline and to characterize change in relation to a minimally important difference (MID) threshold of half an SD. RESULTS Improvements in condition-specific HRQOL met the MID threshold. Reductions from baseline in the DDS total score and its four DDS subscales (all P ≤ 0.0013) and in the HFS total score and its two subscales (all P < 0.0001) were observed across all time points. Improvements were observed after both 1 and 2 years for the EQ-5D visual analog scale (both P < 0.0001). CONCLUSIONS In CIT-07, 87.5% of the subjects achieved the primary end point of freedom from SHE along with glycemic control (HbA1c <7% [<53 mmol/mol]) at 1 year post-initial islet transplantation. The same subjects reported consistent, statistically significant, and clinically meaningful improvements in condition-specific HRQOL as well as self-assessments of overall health.

Abstract
BACKGROUND AND OBJECTIVE The negative impact of hypoglycemia on patients with type 1 diabetes mellitus (T1DM) may lead to development of fear of hypoglycemia. In this study, the original Hypoglycemia Fear Survey (HFS) questionnaire was translated into Spanish, adapted and validated, and variables associated to fear of hypoglycemia in T1DM were analyzed. MATERIAL AND METHODS The HFS was translated and adapted to Spanish using the forward-backward translation method. The resulting questionnaire, EsHFS, was administrated to a population with T1DM. The following parameters of the questionnaire were analyzed: feasibility, reliability (Cronbach's alpha), content validity (correlating EsHFS and EsDQOL [Diabetes Quality of Life] questionnaire), and stability (by means of test-retest correlation). RESULTS The EsHFS questionnaire consists of 24 items and three subscales including: subscale 1 on worry; subscale 2 on hypoglycemia-avoidant behavior, and subscale 3 on hyperglycemia-influenced behavior. STUDY POPULATION 163 subjects, with a mean aged (SD) of 36 (10.5) years, 24% on continuous subcutaneous insulin infusion. Of these, 99.8% completed the EsHFS questionnaire in less than 10minutes. Cronbach's alpha for global EsHFS was 0.92. EsHFS and its subscales correlated with EsDQOL. Test-retest correlation (Pearson) was r=0.92. Age, female sex, lower educational level, living alone, frequency of daily self-monitoring and non-severe hypoglycemia, and history of severe and/or asymptomatic hypoglycemia were independently associated to the result of EsHFS. CONCLUSIONS The Spanish version of the HFS, EsHFS, has good psychometric properties and may be a useful tool to assess fear of hypoglycemia in Spanish-speaking patients with T1DM.

Abstract
PURPOSE The purpose of this study was to examine how fear of hypoglycemia (FOH) is associated with glycemic variability (GV) and self-management behavior in young adults (aged 18-35) with type 1 diabetes (T1DM). PROCEDURES Using a prospective repeated-measures design, in 35 young adults, within- and between-person and temporal associations of FOH, specific self-management behaviors, and GV were measured. The data were collected using questionnaires and real-time measures using daily diaries, insulin pump downloads, actigraphy, and continuous glucose monitoring. FINDINGS FOH was associated with greater glycemic variability. Significant temporal associations emerged. Concurrent day (glucose SD, p=.011) and previous-evening fear levels were associated with GV (glucose SD, p=.007). FOH was also associated with greater calorie intake (r=.492, p=.003) and less physical activity (light activity, r=-.341, p=.045). CONCLUSIONS The significant associations of FOH with GV, dietary patterns, and physical activity provide evidence for FOH as an important psychological factor associated with diabetes care.

Abstract
AIMS To examine the associations among fear of hypoglycaemia, diabetes-related quality of life and psychological well-being, and determine whether diabetes-related quality of life is a mediator of the relationship between fear of hypoglycaemia and psychological well-being in adults with Type 1 diabetes. METHODS A total of 235 of 319 invited adults (18-69years) with Type 1 diabetes agreed to participate. Hierarchical linear regression was applied to 188 individuals with complete data. Mediation analysis was used to determine whether diabetes-related quality of life mediated the relationship between fear of hypoglycaemia and psychological well-being. RESULTS Fear of hypoglycaemia was significantly associated with diabetes-related quality of life and psychological well-being. The behaviour and worry components of fear of hypoglycaemia were significantly associated with diabetes-related quality of life (behaviour component: unstandardised coefficient=-0.04, p<0.001, standardised coefficient=-0.40; worry component: unstandardised coefficient=-0.01, p=0.041, standardised coefficient=-0.18). Fear of hypoglycaemia worry had a significant independent association with psychological well-being (unstandardised coefficient=-0.28, p=0.009, standardised coefficient=-0.25), whereas fear of hypoglycaemia behaviour did not. Diabetes-related quality of life mediated approximately half of the association between fear of hypoglycaemia worry and psychological well-being. CONCLUSIONS Hypoglycaemic episodes can have serious consequences, and assessing fear of hypoglycaemia might help health care providers offer suitable care strategies to individuals with Type 1 diabetes.

Abstract
There has been a 2% to 3% increase in Type 1 diabetes (T1D) in children below 11 years old. Preteens (9-12 years old) with T1D are often overlooked regarding future diabetes self-management (DSM) expectations because parents are still in the "driver's seat." The study purpose was to explore feasibility/ability to recruit and conduct a two-arm trial on reeducation, collaboration, and social support. One component of DSM was reviewed (hypoglycemia) with preteens (n = 22) and parents (n = 22). The experimental preteens discussed hypoglycemia management with a teen mentor and nurse educator using a human patient simulator for practice, and working collaboratively with parents. Concurrently, mothers met with a parent mentor and psychologist to discuss growth and development, and collaborative shared management. Comparison dyads discussed hypoglycemia management with a nurse. Preteens slightly improved in diabetes knowledge; the experimental arm had higher problem-solving scores. Parents in the experimental arm had higher self-efficacy scores. Findings will inform future research.

Acta Diabetol 2016; 53:833-8. [PMID: 27421991 DOI: 10.1007/s00592-016-0881-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2016] [Accepted: 06/27/2016] [Indexed: 01/06/2023]
Abstract
AIMS The occurrence of hypoglycaemia is assumed to be associated with increased diabetes-related distress. We investigated the association of mild hypoglycaemia (MH) with diabetes-related distress in a large outpatient cohort with diabetes type 1 (DM1) and type 2 (DM2). METHODS In a cross-sectional study, we recorded MH and simultaneously assessed diabetes-related distress with the PAID questionnaire in 783 people with diabetes [female 43.8 %, age 63.7 years, duration of diabetes 17.3 years, HbA1c 7.0 % (53 mmol/mol)] in an university outpatient department for metabolic diseases over a period of three months. Participants with and without MH were compared. RESULTS People with DM1 (n = 191) had 1.09 MH per week. Diabetes-related distress was not different comparing people with DM1 with (n = 125) and without (n = 66) MH (PAID score 18.4 ± 16.2 vs. 16.6 ± 15.0, p = 0.449). The frequency of MH per week in people with DM2 on oral antidiabetic therapy (n = 182) and with insulin therapy (n = 410) is low (0.03 vs. 0.1 episodes). People with DM2 on insulin therapy with (n = 72) and without (n = 338) MH have a comparable PAID score (17.9 ± 13.3 vs. 16.8 ± 14.9, p = 0.552). 14.4 % of those with DM1 as well as 12.5 % of those with DM2 on insulin feel hypoglycaemic events to be a "somewhat serious problem" or "serious problem". CONCLUSIONS In an outpatient setting, MH is not associated with increased diabetes-related distress or burden in people with DM1 or DM2.

Abstract
OBJECTIVE We examined (a) the demographic and clinical correlates of worries about hypoglycemia in adult family members of adults with diabetes, and (b) the association of these worries with measures of diabetes support. METHODS The second multinational Diabetes Attitudes, Wishes and Needs (DAWN2) study cross-sectionally surveyed 2057 family members from 17 countries. Participants completed questions about demographics, diabetes, and psychosocial functioning, including worry about overall and nocturnal hypoglycemia. Analyses included hierarchical ordinal and linear regression. RESULTS Eighty-five percent of family members (n=1661) were at least occasionally very worried about the risk of hypoglycemic events overall. Correlates of worries about hypoglycemia included female gender, higher age and lower education in the family member, younger age of the person with diabetes and this person being a parent or another adult (versus spouse or partner), insulin or non-insulin injectable treatment, severe or non-severe hypoglycemia in the past 12months, and family member recognition of hypoglycemia. Elevated worries about hypoglycemia had a significant independent association with increased odds of diabetes-related family arguments and family member frustration in providing helpful support (OR range 1.60-3.72). High levels of worries about hypoglycemia were associated with increased odds of attending diabetes-related health-care visits. Worries about hypoglycemia were not associated with family member involvement in diabetes care. Similar results were found for worries about nocturnal events. CONCLUSION Worries about hypoglycemia were common in family members and were associated with suboptimal diabetes support. This issue therefore deserves increased clinician attention.

Abstract
This review outlines the current state of knowledge regarding a unique neural defect of the pancreatic islet in autoimmune diabetes, one that we have termed early sympathetic islet neuropathy (eSIN). We begin with the findings that a majority of islet sympathetic nerves are lost near the onset of type 1, but not type 2, diabetes and that this nerve loss is restricted to the islet. We discuss later work demonstrating that while the loss of islet sympathetic nerves and the loss of islet beta cells in type 1 diabetes both require infiltration of the islet by lymphocytes, their respective mechanisms of tissue destruction differ. Uniquely, eSIN requires the activation of a specific neurotrophin receptor and we propose two possible pathways for activation of this receptor during the immune attack on the islet. We also outline what is known about the functional consequences of eSIN, focusing on impairment of sympathetically mediated glucagon secretion and its application to the clinical problem of insulin-induced hypoglycaemia. Finally, we offer our view on the important remaining questions regarding this unique neural defect.

Abstract
In humans, the glucagon response to moderate-to-marked insulin-induced hypoglycemia (IIH) is largely mediated by the autonomic nervous system. Because this glucagon response is impaired early in type 1 diabetes, we sought to determine if these patients, like animal models of autoimmune diabetes, have an early and severe loss of islet sympathetic nerves. We also tested whether this nerve loss is a permanent feature of type 1 diabetes, is islet-selective, and is not seen in type 2 diabetes. To do so, we quantified pancreatic islet and exocrine sympathetic nerve fiber area from autopsy samples of patients with type 1 or 2 diabetes and control subjects without diabetes. Our central finding is that patients with either very recent onset (<2 weeks) or long duration (>10 years) of type 1 diabetes have a severe loss of islet sympathetic nerves (Δ = -88% and Δ = -79%, respectively). In contrast, patients with type 2 diabetes lose no islet sympathetic nerves. There is no loss of exocrine sympathetic nerves in either type 1 or type 2 diabetes. We conclude that patients with type 1, but not type 2, diabetes have an early, marked, sustained, and islet-selective loss of sympathetic nerves, one that may impair their glucagon response to IIH.

Abstract
Adrenaline is a hormone that has profound actions on the cardiovascular system and is also a mediator of the fight-or-flight response. Adrenaline is now increasingly recognized as an important metabolic hormone that helps mobilize energy stores in the form of glucose and free fatty acids in preparation for physical activity or for recovery from hypoglycaemia. Recovery from hypoglycaemia is termed counter-regulation and involves the suppression of endogenous insulin secretion, activation of glucagon secretion from pancreatic α-cells and activation of adrenaline secretion. Secretion of adrenaline is controlled by presympathetic neurons in the rostroventrolateral medulla, which are, in turn, under the control of central and/or peripheral glucose-sensing neurons. Adrenaline is particularly important for counter-regulation in individuals with type 1 (insulin-dependent) diabetes because these patients do not produce endogenous insulin and also lose their ability to secrete glucagon soon after diagnosis. Type 1 diabetic patients are therefore critically dependent on adrenaline for restoration of normoglycaemia and attenuation or loss of this response in the hypoglycaemia unawareness condition can have serious, sometimes fatal, consequences. Understanding the neural control of hypoglycaemia-induced adrenaline secretion is likely to identify new therapeutic targets for treating this potentially life-threatening condition.

Abstract
OBJECTIVE To evaluate mini-dose glucagon in adults with type 1 diabetes using a stable, liquid, ready-to-use preparation. RESEARCH DESIGN AND METHODS Twelve adults with type 1 diabetes receiving treatment with insulin pumps received subcutaneous doses of 75, 150, and 300 μg of nonaqueous glucagon. Plasma glucose, glucagon, and insulin concentrations were measured. At 180 min, subjects received insulin followed in ~60 min by a second identical dose of glucagon. RESULTS Mean (±SE) fasting glucose concentrations (mg/dL) were 110 ± 7, 110 ± 10, and 109 ± 9 for the 75-, 150-, and 300-μg doses, respectively, increasing maximally at 60 min by 33, 64, and 95 mg/dL (all P < 0.001). The post-insulin administration glucose concentrations were 70 ± 2, 74 ± 5, and 70 ± 2 mg/dL, respectively, with maximal increases of 19, 24, and 43 mg/dL post-glucagon administration (P < 0.02) at 45-60 min. CONCLUSIONS Subcutaneous, nonaqueous, ready-to-use G-Pen Mini glucagon may provide an alternative to oral carbohydrates for the management of anticipated, impending, or mild hypoglycemia in adults with type 1 diabetes.

Abstract
Aims We studied the association between fear of hypoglycaemia (FoH) and various diabetes self-management practices. Methods Data from 798 individuals with type 1 diabetes participating in the FinnDiane Study were included. Self-reported questionnaires were used to assess FoH and self-management practices (e.g. dietary intake, insulin administration, physical activity). For glycaemic control, we used both the latest HbA1c measurements and the serial HbA1c measurements from the medical files. Factor analysis was used to reveal underlying constructs within the food frequency section of the diet questionnaire. Results In all, 44% and 63% of men and women reported FoH, respectively. In men, FoH was associated with higher mean serial HbA1c levels, higher number of reported self-monitoring of blood glucose (SMBG), higher carbohydrate intake, and lower scores in the "high-fat" factor. In women, FoH was associated with a higher number of reported SMBGs and higher energy intake. No difference was observed in physical activity and insulin administration. Conclusions FoH has various implications for the self-management of diabetes. More studies are however needed to assess on one hand the association between FoH and diabetes self-management, and on the other hand, FoH and its long term consequences, such as the emergence of diabetic complications and mortality.

Abstract
PURPOSE This review summarizes the current state of the science related to fear of hypoglycemia (FOH) in adults with type 1 diabetes. Fear of hypoglycemia is a critical deterrent to diabetes self-management, psychological well-being, and quality of life. We examine the influence of contemporary treatment regimens, technology, and interventions to identify gaps in knowledge and opportunities for research and practice. BASIC PROCEDURES A literature search was conducted of MEDLINE, PsycINFO, and EMBASE. Fifty-three studies that examined fear of hypoglycemia were included. MAIN FINDINGS Fear of hypoglycemia influences diabetes management and quality of life. Gender and age differences exist in experiences and responses. Responses vary from increased vigilance to potentially immobilizing distress. Fear of hypoglycemia is greater at night and may contribute to poor sleep quality. Strategies to reduce fear of hypoglycemia have had varying success. Newer technologies hold promise but require further examination. CONCLUSIONS Fear of hypoglycemia remains a problem, despite advances in technology, insulin analogs, and evidence-based diabetes management. Clinical care should consistently include assessment for its influence on diabetes self-management and psychological health. Further research is needed regarding the influence of newer technologies and individualized strategies to reduce fear of hypoglycemia while maintaining optimal glucose control.
