Abstract
Type 1 diabetes is associated with both acute and chronic complications. Acute complications include diabetic ketoacidosis and severe hypoglycemia. Chronic complications can be microvascular or macrovascular. Microvascular complications include retinopathy, nephropathy, and neuropathy. The pathophysiology of microvascular complications is complex. Hyperglycemia is a common underlying risk factor, underscoring the importance of optimizing glycemic management. Patients with type 1 diabetes are also at increased risk of macrovascular complications including coronary artery disease and vascular disease. The American Diabetes Association provides screening guidelines for chronic complications of diabetes. Adherence to these guidelines is an important aspect of diabetes care.

Abstract
Objective: To assess the clinical impact of flash glucose monitoring (FGM) systems on fear of hypoglycemia (FoH) and quality of life in adults with type 1 diabetes mellitus (T1DM). Methods: Prospective quasi-experimental study with a 12-month follow-up. People with T1DM (18-80 years old) and self-monitoring by blood capillary glycemia controls were included. The FH15 questionnaire, a survey validated in Spanish in a comparable study population, was used to diagnose FoH with a cutoff point of 28 points. Results: A total of 181 participants were included, with a FoH prevalence of 69% (n = 123). A mean reduction in FH15 score of -4 points (95% confidence interval [-5.5 to -3]; P < 0.001) was observed, along with an improvement in quality of life (EsDQOL-test (Diabetes Quality of Life, Spanish version), -7 points [-10; -4], P < 0.001) and satisfaction with treatment (Diabetes Treatment Satisfaction questionnaire, self-reported version [DTSQ-s] test, +4.5 points [4; 5.5], P < 0.001). At the end of the follow-up, 64.2% of the participants saw an improved FoH intensity, compared to 35.8% who scored the same or higher. This improvement in FoH status was associated with a higher time-in-range at the end of the follow-up (P = 0.003), as well as a lower time spent in hyperglycemia (P = 0.005). In addition, it was linked to participants with a high baseline FoH levels (P < 0.001) and those who were university degree holders (P = 0.07). Conclusions: FGM is associated with an overall reduction of FoH in adults with T1DM and with an increase in their quality of life. Nevertheless, a significant percentage of patients may experience an increase of this phenomenon leading to clinical repercussions and a profound impact on quality of life.

Abstract
BACKGROUND Glucose imbalance is common in total parenteral nutrition (TPN). Hypoglycemia seems to be less frequent than hyperglycemia, but it influences the clinical outcome to a greater extent. Therefore, it should be effectively prevented and treated. However, there is no relevant report on how to treat hypoglycemia caused by TPN in patients with liver cell injury. CASE SUMMARY We present three patients with liver cell injury who developed severe hypoglycemia during or after TPN infusion. The causes of severe hypoglycemia and glucose-raising strategies were discussed. According to the physiological characteristics of the hepatocellular injury, the ratio of nutrition components prescribed in TPN was appropriately adjusted for the three cases. We simultaneously reduced the dose of insulin and fat emulsion, and increased the dose of glucose in TPN. The blood glucose level was restored to normal range and clinical symptoms were eliminated. CONCLUSION When hypoglycemia occurs during or after TPN in patients with hepatocellular injury, physicians need to simultaneously reduce insulin and fat emulsion, and increase glucose, and correct severe hypoglycemia in time to reduce its adverse consequences.

Abstract
Severe hypoglycemia is closely related to adverse cardiovascular outcomes in patients with diabetes; however, the specific mechanism remains unclear. We previously found that severe hypoglycemia aggravated myocardial injury and cardiac dysfunction in diabetic mice, and that the mechanism of damage was related to mitochondrial oxidative stress and dysfunction. Based on the key regulatory role of mitophagy in mitochondrial quality control, this study aimed to further explore whether the myocardial damage caused by severe hypoglycemia is related to insufficient mitophagy and to clarify their underlying regulatory relationship. After severe hypoglycemia, mitochondrial reactive oxygen species increased, mitochondrial membrane potential and ATP content decreased, and pathological mitochondrial damage was aggravated in the myocardium of diabetic mice. This was accompanied by decreased mitochondrial biosynthesis, increased fusion, and downregulated PTEN-induced kinase 1 (PINK1)/Parkin-dependent mitophagy. Treating diabetic mice with the mitophagy activator and polyphenol metabolite urolithin A activated PINK1/Parkin-dependent mitophagy, reduced myocardial oxidative stress and mitochondrial damage associated with severe hypoglycemia, improved mitochondrial function, alleviated myocardial damage, and ultimately improved cardiac function. Thus, we provide insight into the prevention and treatment of diabetic myocardial injury caused by hypoglycemia to reduce adverse cardiovascular outcomes in patients with diabetes.

Abstract
AIMS Evaluate the effectiveness of reimbursed flash glucose monitoring with optional alarms (FGM) in preventing severe hypoglycemia (SH) and reducing hypoglycemia exposure in T1D patients prone to hypoglycemia. METHODS Ambispective study in T1D patients treated with multiple daily injections (MDI) and prone to hypoglycemia, initiating reimbursed FGM (FreeStyle Libre 2). The primary outcome was the number of SH events (requiring third party assistance) and main secondary outcomes were time below range < 70 (TBR < 70) and < 54 mg/dL (TBR < 54), impaired awareness of hypoglycemia (IAH) and quality of life (QoL). Logistic regression models were constructed to explore variables associated with success of the intervention. RESULTS We included 110 patients (52.7 % women, mean age 47.8 ± 17.0 years). SH events at 1-year follow-up decreased from 0.3 ± 0.6 to 0.03 ± 0.2 (p < 0.001). Significant reductions in patients presenting an SH (26.4 % vs. 2.9 %, p < 0.001) and IAH (47.1 % vs. 25.9 %, p = 0.002) were observed, as well as improvements in QoL. TBR < 70 and TBR < 54 were not significantly reduced. Baseline GMI was inversely associated with a decrease in TBR < 70 [OR 0.37 (0.15-0.93)] and directly with an increase in time in range 70-180 mg/dL [OR 2.10 (1.03-4.28)]. CONCLUSIONS FGM decreased SH and improved hypoglycemia awareness and QoL. Initial tight glycemic control was associated with a decrease in hypoglycemia, while patients with suboptimal control reduced hyperglycemia.

Abstract
INTRODUCTION Second-generation basal insulin analogues have been shown to reduce hypoglycemia in several trials and observational studies of select populations; however, it remains unclear whether these results persist in real-world settings. Using self-reported hypoglycemia events, we assessed whether second-generation basal insulin analogues reduce rates of hypoglycemia events (non-severe/severe; overall/daytime/nocturnal) compared to earlier intermediate/basal insulin analogues among people with insulin-treated type 1 or 2 diabetes. METHODS We used prospectively collected data from the Investigating Novel Predictions of Hypoglycemia Occurrence Using Real-World Models (iNPHORM) panel survey. This US-wide, 1-year internet-based survey assessed hypoglycemia experiences and related sociodemographic and clinical characteristics of people with diabetes (February 2020-March 2021). We estimated population-average rate ratios for hypoglycemia comparing second-generation to earlier intermediate/basal insulin analogues using negative binomial regression, adjusting for confounders. Within-person variability of repeated observations was addressed with generalized estimating equations. RESULTS Among iNPHORM participants with complete data, N = 413 used an intermediate/basal insulin analogue for ≥ 1 month during follow-up. After adjusting for baseline and time-updated confounders, average second-generation basal insulin analogue users experienced a 19% (95% CI 3-32%, p = 0.02) lower rate of overall non-severe hypoglycemia and 43% (95% CI 26-56%, p < 0.001) a lower rate of nocturnal non-severe hypoglycemia compared to earlier intermediate/basal insulin users. Overall severe hypoglycemia rates were similar among second-generation and earlier intermediate/basal insulin users (p = 0.35); however, the rate of severe nocturnal hypoglycemia was reduced by 44% (95% CI 10-65%, p = 0.02) among second-generation insulin users compared to earlier intermediate/basal insulin users. CONCLUSION Our real-world results suggest second-generation basal insulin analogues reduce rates of hypoglycemia, especially nocturnal non-severe and severe events. Whenever possible and feasible, clinicians should prioritize prescribing these agents over first-generation basal or intermediate insulin in people with type 1 and 2 diabetes.

Abstract
INTRODUCTION This study aimed to understand the actual status of multimorbidity and polypharmacy among patients with type 2 diabetes using glucose-lowering drugs, and to assess the effects of patient characteristics on severe hypoglycemia and glycemic control. METHODS We designed a retrospective cohort study using health insurance claims and medical checkup data in Japan from April 2016 to February 2021 and identified patients with type 2 diabetes who were prescribed glucose-lowering drugs. We analyzed data on patient characteristics, including multimorbidity and polypharmacy, calculated the incidence rate for severe hypoglycemic events, applied a negative binomial regression model to explore factors that affected severe hypoglycemia, and analyzed the status of glycemic control in the subcohort for which HbA1c data were available. RESULTS Within the analysis population (n = 93,801), multimorbidity was present in 85.5% and mean ± standard deviation for oral drug prescriptions was 5.6 ± 3.5 per patient, while for those aged 75 years or older these numbers increased to 96.3% and 7.1 ± 3.5, respectively. The crude incidence rate for severe hypoglycemia was 5.85 (95% confidence interval 5.37, 6.37) per 1000 person-years. Risk factors for severe hypoglycemia included younger and older age, prior severe hypoglycemia, use of insulin, sulfonylurea, two-drug therapy including sulfonylurea or glinides, three-or-more-drug therapy, excessive polypharmacy, and comorbidities including end-stage renal disease (ESRD) requiring dialysis. Subcohort analysis (n = 26,746) showed that glycemic control is not always maintained according to guidelines. CONCLUSION Patients with type 2 diabetes, particularly older patients, experienced high multimorbidity and polypharmacy. Several risk factors for severe hypoglycemia were identified, most notably younger age, ESRD, history of severe hypoglycemia, and insulin therapy.

Abstract
Objective: Nationwide reimbursement of intermittently scanned continuous glucose monitoring (isCGM) was introduced in Belgium (2016). This real-world observational study investigates the impact of isCGM over 24 months on adults with type 1 diabetes with impaired or normal awareness of hypoglycemia (IAH or NAH). Methods: We included 1905 people who started first-generation 14-day FreeStyle Libre (without alerts). Sixteen percent had IAH. Primary endpoint was evolution of quality of life (QOL); secondary endpoints were evolution of severe hypoglycemia, work absenteeism, glycated hemoglobin (HbA1c), and sensor-measured outcomes. Results: At baseline, people with IAH (n = 308) had significantly worse QOL than people with NAH (n = 1594). Only people with IAH improved on the hypoglycemia fear survey-worry subscale after 24 months (22.8 [95% confidence interval: 21.4-24.2] at baseline; 20.6 [19.0-22.1] at 24 months, P = 0.002). For both groups, Diabetes Treatment Satisfaction Scale improved over 24 months (IAH: +3.1 [2.1-4.1], P < 0.001; NAH: +2.3 [1.9-2.7], P < 0.001), whereas general QOL, diabetes distress, and HbA1c remained stable. People with IAH showed the strongest decline in work absenteeism and severe hypoglycemia (36.4% having an event 6 months before isCGM initiation; 16.0% having an event during last 6 months of follow-up, P < 0.001), with similar observations for hypoglycemia hospitalization and hypoglycemia coma. Over 24 months, people with IAH spent more time in hypoglycemia, but less time in hyperglycemia than people with NAH. Conclusion: These data show sustained improvement of severe hypoglycemia, work absenteeism, and hypoglycemia fear after isCGM reimbursement, mostly driven by people with IAH. Together with improved treatment satisfaction, irrespective of hypoglycemia awareness level, isCGM without alerts is a valuable tool under long-term real-world conditions.

Abstract
Aims/Hypothesis: Initiation of insulin therapy in people with type 2 diabetes (T2DM) may be necessary to achieve glycemic targets but is associated with acute diabetes events (ADEs), including severe hypoglycemia (SH) or diabetic ketoacidosis (DKA). We assessed the impact of initiating FreeStyle Libre® system (FSL) on hospitalizations for ADEs in people with T2DM on basal insulin only regimen±noninsulin antidiabetic drugs. Materials and Methods: A retrospective study of the French national Système National des Données de Santé reimbursement claims database (≈66 million French people) identified people with T2DM on basal insulin therapy receiving a first reimbursement of FSL between August 1, 2017 and December 31, 2018. Claims data for the 12 months before, and up to 24 months after FSL initiation, were analyzed. Hospitalizations for ADEs were identified, using ICD-10 codes as main or related diagnosis, for: SH events; DKA events; comas; and hyperglycemia-related admissions. Results: A total of 5933 people with T2DM on basal insulin therapy initiated FSL during the selection period. Of the patients, 78.9% were on basal insulin and other hypoglycemic agents. Among the 5933 patients identified, 2.01% had at least one hospitalization for any ADE in the year before FSL initiation, compared to 0.75% (1 year) and 0.60% (2 years). Reductions in ADEs were driven by 75% fewer DKA admissions, with a 44% reduction in SH admissions. These patterns of reduced ADEs persisted after 2 years, with a further 43% reduction in DKA rates. Conclusions/Interpretation: This study emphasizes the value of the FSL system in reducing ADEs in people with T2DM in France not on intensive insulin therapy and initially treated with basal-only insulin therapy.

Abstract
Glucagon (traditional kits for intramuscular administration, Glucagon and Glucagen), although recommended as a remedy for severe hypoglycemia (SH), has been reported to be under-utilized, likely because of technical problems. The aims of this study were to evaluate the use of glucagon in persons with type 1 diabetes in several countries, and to investigate if the availability of new ready-to-use glucagons (Baqsimi, Gvoke, Zegalogue, years 2019 to 2021) has expanded the overall use of glucagon. The source of data was IQVIA-MIDAS (units of glucagon sold), while data on persons with type 1 diabetes in countries were derived from IDF Diabetes Atlas. The use of glucagon has been steady from 2014 to 2019, with a small but significant increase from 2019 to 2021, paradoxically only in countries where new ready-to-use glucagons were not available. The use of glucagon has always been ten fold greater in countries where new ready-to-use glucagons became available than in the other countries (population 108,000,000 vs 28,100,000, 480,291 vs 182,018 persons with type 1 diabetes). A significant correlation was observed in all years between units of glucagon and persons with type 1 diabetes. Availability of new ready-to-use glucagons was associated with a small increase of sales, due only to new ready-to-use glucagons themselves. The use of glucagon (any type) remains low, approximately 1/10 of persons with type 1 diabetes. We conclude that use of glucagon is scarce in most countries, and so far has not been expanded by new ready-to-use glucagons such as the ones considered in this study.

Abstract
AIMS We aimed to determine if severe hypoglycemia (SH) independently increases the risk of hospitalization for heart failure (hHF) in type 2 diabetes, regardless of the prevalent or incident cardiovascular disease (CVD). METHODS This was a nationwide population-based propensity score-matched study using Korean National Health Insurance Service data (2002-2018). The hazards of hHF were compared in individuals who experienced SH (n = 8,965) and 1:3 matched controls, among adults with diabetes using oral anti-diabetes medications (OADs) with or without insulin and without previous hHF at baseline. RESULTS During 236,417 person-years, 1,189 cases of hHF occurred. The hazard of hHF was higher in individuals with SH compared to matched controls (adjusted hazard ratio [aHR] 1.503, 95 % confidence interval [CI] 1.324-1.707). The increase in aHR remained significant when excluding participants with prevalent or incident major adverse cardiovascular events (MACE; aHR 1.352, 95 % CI 1.228-1.622) and any CVD (aHR 1.342, 95 % CI 1.025-1.756). Two or more SH events were associated with further increase in hHF risk. CONCLUSION SH was associated with increased risks of hHF among adults with diabetes using OAD with or without insulin. The increased risk was attenuated but remained significant in those without prevalent or incident MACE or CVDs.

Abstract
Objective: We combined data from two landmark trials (DIAMOND and HypoDE) to examine the diagnostic performance of low glucose measurements derived from open and masked continuous glucose monitoring (CGM) to predict the occurrence of future severe hypoglycemia (SH). Methods: We analyzed hypoglycemia parameters (low blood glucose index [LBGI], % <70 mg/dL, 54-69 mg/dL [level 1 hypoglycemia] and <54 mg/dL [level 2 hypoglycemia]) from masked CGM over 14 days during baseline and from open CGM over 14 days after randomization. We used receiver operating characteristics (ROC) curves to evaluate the screening performance of these measures to predict future SH. Positive likelihood ratios were calculated to indicate the overall diagnostic performance of these parameters. Results: Data from 288 individuals with type 1 diabetes (mean age 45.6 ± 12.8 years, diabetes duration 20.7 ± 13.7 years, HbA1c 8.2% ± 1.0%, Hypoglycemia Unawareness Score 3.4 ± 2.1) were analyzed. Area under ROC-curve (AUC) for LBGI and % <70 mg/dL ranged between 0.68 and 0.75, indicating that LBGI and % <70 mg/dL could significantly predict future SH. Significance of AUC regarding % <54 mg/dL were mixed (0.63-0.72). Positive and negative likelihood ratios ranged between 1.82 to 3.40 and 0.56 to 0.32, respectively. Suggested optimal cutoff values were remarkedly lower in open CGM than in masked CGM. Conclusion: These results indicate that CGM-derived hypoglycemic parameters have a good screening performance to significantly predict future clinical hypoglycemia. In addition, this analysis suggests that cutoff values to indicate elevated hypoglycemia risk in the future are substantially lower in open CGM than in masked CGM. ClinicalTrials.gov registration numbers: HypoDE: NCT02671968. DIAMOND: NCT02282397.

Abstract
AIMS/INTRODUCTION We investigated the associations between a combination of lifestyle factors and changes to these factors and the subsequent risk of severe hypoglycemia (SH) in type 2 diabetes patients. MATERIALS AND METHODS Individuals with adult type 2 diabetes who underwent consecutive 2-year interval health screening programs from 2009 to 2012 from the Korean National Health Insurance Service database were included and followed up until 2018. Information on history of smoking status, alcohol consumption and physical activity, as well as changes to these factors, was obtained. The primary outcome was incident SH. RESULTS Of the 1,490,233 type 2 diabetes patients, 30,539 (2.1%) patients developed SH. Current smokers and heavy drinkers had increased risk of SH, compared with non-smokers and non-drinkers, respectively (hazard ratio 1.28, 95% confidence interval 1.23-1.34; hazard ratio 1.22, 95% confidence interval 1.15-1.30). However, regular physical activity was associated with reduced SH risk (hazard ratio 0.79, 95% confidence interval 0.77-0.82). A combination of unhealthy lifestyle habits was associated with increased SH risk in a dose-dependent fashion (P for trend <0.001). Compared with participants without changes in their unhealthy lifestyles, participants who improved lifestyles had decreased risk of SH. CONCLUSIONS Greater adherence to healthy lifestyle factors and any improvement in unhealthy lifestyle habits were associated with a substantially lower risk of SH in individuals with type 2 diabetes.

Abstract
BACKGROUND Hypoglycemia unawareness designates failure to detect eminent hypoglycemia. Clarke's questionnaire is one of the most used systems to evaluate this problem. AIMS To relate Clarke's questionnaire (QQ) results with continuous glucose monitoring data. METHODS Application of the questionnaire in a sample of type 1 diabetes mellitus (T1DM) patients using intermittent continuous glucose monitoring (iCGM). RESULTS 111 T1DM patients were evaluated, 56.8% female, mean age 35.0 ± 12.4 years and mean disease duration 18.8 ± 10.5 years. According to CQ, 13.5% had unawareness, 76.6% awareness and 9.9% indeterminate awareness to hypoglycemia. Those with unawareness had longer disease duration (25.1 ± 10.4 vs 18.2 ± 10.3 for awareness and 14.9 ± 9.9 for indeterminate awareness, p = 0.047), more time below range (10.3 ± 4.9% vs 6.3 ± 5.1 and 6.3 ± 4.8; p = 0.009) and higher mean duration of hypoglycemia (131.7 ± 38.6 vs 116.6 ± 49.6 and 131.7 ± 38.6; p = 0.008). In multivariate analysis, mean duration of hypoglycemia was an independent predictor of CQ results. In a receiver operating curve (AUC 0.746; p = 0.004) a mean duration of hypoglycemia ≥106.5 min showed 84.6% sensitivity/64.4% specificity for unawareness. CONCLUSIONS Our sample had a significative prevalence of hypoglycemia unawareness which increased with longer diabetes duration. iCGM data can be indicative of this problem, with a mean hypoglycemia duration ≥106.5 min being suggestive, albeit unspecific.

Abstract
PURPOSE OF REVIEW The purpose of this paper is to describe rescue glucagon types, safety, efficacy, and preferences, as well as to review articles regarding emergency glucagon usage, severe hypoglycemia, and the emotions of both phenomena. We conducted a review of current literature on glucagon usage and the emotional impact of severe hypoglycemia on people with diabetes (PwD) and the caregivers of people with type 1 diabetes (T1D). RECENT FINDINGS Minimal research exists pertaining to glucagon and severe hypoglycemic experiences in PwD, which is troubling considering the severity of risks and possible side effects. Recent articles described negative emotions such as fear, anxiety, stress, helplessness, shame, embarrassment, loneliness, frustration, hopefulness, and uncertainty surrounding glucagon usage. There is scarce research regarding PwD's emotions surrounding severe hypoglycemia and rescue glucagon use. Additional research is needed to investigate the emotions and feelings people with T1D and their caregivers' experience pertaining to severe hypoglycemia and emergency glucagon use.

Abstract
INTRODUCTION Severe hypoglycemic events (SHE) represent a clinical and economic burden in patients with diabetes. Nasal glucagon (NG) is a novel treatment for SHEs with similar efficacy, but with a usability advantage over injectable glucagon (IG) that may translate to improved economic outcomes. The economic implications of this usability advantage on SHE-related spending in Spain were explored in this analysis. METHODS A cost-offset and budget impact analysis (BIA) was conducted using a decision tree model, adapted for the Spanish setting. The model calculated average costs per SHE over the SHE treatment pathway following a treatment attempt with IG or NG. Analyses were performed separately in three populations with insulin-treated diabetes: children and adolescents (4-17 years) with type 1 diabetes (T1D), adults with T1D and adults with type 2 diabetes (T2D), with respective population estimates applied in BIA. Treatment probabilities were assumed to be equal for IG and NG, except for treatment success following glucagon administration. Epidemiologic and cost data were obtained from Spanish-specific sources. BIA results were presented at a 3-year time horizon. RESULTS On a per SHE level, NG was associated with lower costs compared to IG (children and adolescents with T1D, EUR 820; adults with T1D, EUR 804; adults with T2D, EUR 725). Lower costs were attributed to reduced costs of professional medical assistance in patients treated with NG. After 3 years, BIA showed that relative to IG, the introduction of NG was projected to reduce SHE-related spending by EUR 1,158,969, EUR 142,162,371, and EUR 6,542,585 in children and adolescents with T1D, adults with T1D, and adults with insulin-treated T2D, respectively. CONCLUSIONS In Spain, the usability advantage of NG over IG translates to potential cost savings per SHE in three populations with insulin-treated diabetes, and the introduction of NG was associated with a lower budget impact versus IG in each group.

Abstract
To estimate the trends in the prevalence of severe hypoglycemia (SH) in patients with type 2 diabetes in Korea, we investigated the total number of SH episodes among type 2 diabetes patients aged ≥30 years who visited the emergency department between 2002 and 2019, using the Korean National Health Insurance Service database. The prevalence of SH events increased from 2002 to 2012; however, it has decreased gradually since 2012. In 2019, the prevalence of SH was 0.6%, with an incidence rate of 4.43 per 1,000 person‐years. Approximately 23,000 SH events occur every year in Korea. Although the incidence is steadily decreasing, there are a considerable number of SH events in type 2 diabetes patients. The decline in the incidence of SH seems to most likely be due to the increased prescription rate of hypoglycemic agents without hypoglycemia risk, less‐strict treatment goals and the individualization of therapy.

Abstract
AIMS The CRASH study examined severe hypoglycemia (SH) experiences among people with diabetes (PWD) and caregivers across eight countries. Here we report findings from the Japan cohort, with references to data from the United Kingdom (UK) cohort. MATERIALS AND METHODS Adults with type 1 (T1DM) or insulin-treated type 2 diabetes mellitus (T2DM) and caregivers (not necessarily related) were recruited from online patient panels. Participants who had experienced at least one SH event in the past 3 years were eligible for study inclusion. Participants completed an online survey regarding their experience with SH, its treatment, and actions during and after an event. RESULTS Of the 9367 PWD and caregivers from the online patient panels, 8475 participants were ineligible and a total of 53 Japanese participants (35 T1DM, 9 T2DM, 9 caregivers) completed the survey. Most SH incidents occurred at home and were unattended by a healthcare provider. For T1DM, 29% of Japan PWD and 13% of the UK PWD called an ambulance during an SH event; of these, 90% (Japan) and 50% (UK) were transported to hospital. Glucagon use was low (3% Japan and 10% UK for T1DM). Japanese respondents reported emotional impacts of SH, including feeling scared (86% T1DM, 56% T2DM), unprepared (63% T1DM, 78% T2DM), and helpless (60% T1DM, 33% T2DM). Despite the emotional burden, most PWD did not immediately discuss their SH event with a healthcare provider, with the majority (75% T1DM, 71% T2DM) waiting until their next doctor's appointment. CONCLUSION Conversations around SH between healthcare providers and PWD appear to be insufficient in Japan. An emotional burden of SH was reported by PWD and caregivers. Education regarding the prevention of SH and available treatment options may reduce SH events and improve treatment preparation, while alleviating PWD concerns.

Abstract
BACKGROUND Self-management of blood glucose levels to avoid hypoglycemia is vital for patients with type 2 diabetes mellitus (T2DM). The association between specific metrics of glycemic variability (glycosylated hemoglobin A1c [HbA1c] and fasting plasma glucose [FPG]) and severe hypoglycemia has not been fully studied in patients with T2DM. METHODS In this post hoc analysis, patients with established T2DM with a high risk of cardiovascular disease were included in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) study. The Cox proportional hazards model was used to investigate the relationship between glycemic variability and hypoglycemia requiring medical assistance (HMA) and hypoglycemia requiring any third-party assistance (HAA). The prognostic value of HbA1c/FPG variability for our predefined outcomes was compared using Harrell's C method. RESULTS After adjusting for confounders, each increase in HbA1c variability of 1 standard deviation (SD) indicated a higher risk of HAA (hazard ratio [HR]: 1.10; 95% confidence interval [CI]: 1.03-1.16; P < 0.01) and HMA events (HR: 1.11; 95% CI: 1.03-1.20; P < 0.01). Meanwhile, each increase in FPG variability of 1 SD increased the risk of HAA (HR: 1.40; 95% CI: 1.31-1.49; P < 0.01) and HMA events (HR: 1.46; 95% CI: 1.35-1.57; P < 0.01). Meanwhile, models, including FPG variability, had better prognostic value for our predefined outcomes than HbA1c variability (P < 0.01). CONCLUSIONS Increased visit-to-visit variability in HbA1c and fasting glycemia is associated with a greater risk of severe hypoglycemic events in T2DM patients. FPG variability is a more sensitive indicator than HbA1c variability. TRIAL REGISTRATION http://www.clinicaltrials.gov. Unique identifier: NCT00000620.

Abstract
AIM The objective of the CRASH (Conversations and Reactions Around Severe Hypoglycemia) survey was to further our understanding of the characteristics, experience, behavior and conversations with healthcare professionals (HCPs) of persons with diabetes (PWD) receiving insulin, and of their caregivers (CGs), concerning hypoglycemia requiring external assistance (severe hypoglycemic events [SHEs]). METHODS CRASH was an online cross-sectional survey conducted across eight countries. The PWDs with self-reported type 1 (T1D) or insulin-treated type 2 (T2D) diabetes were aged ≥18 years and had experienced one or more SHEs in past the 3 years; CGs were non-medical professionals aged ≥18 years, caring for a PWD meeting all the above criteria except for PWD age (≥4 rather than ≥18 years). The present report is a descriptive analysis of data from France. RESULTS Among PWDs who had ever discussed SHEs with an HCP, 38.9% of T1D PWDs and 50.0% of T2D PWDs reported that SHEs were discussed at every consultation; 26.3% and 8.8% respectively had not discussed the most recent SHE with an HCP. 35.7% of T1D PWDs and 53.8% of T2D PWDs reported that glucagon was not available to them at the time of their most recent SHE. Only 16.9% of T1D PWDs and 6.5% of T2D PWDs who had discussed their most recent SHE with an HCP reported that the HCP recommended obtaining a glucagon kit or asked them to confirm that they already had one. High proportions of PWDs and CGs reported that the most recent SHE had made them feel unprepared, scared and helpless and had affected mood, emotional state and activities. CONCLUSION CRASH survey data from France identify a need for greater discussion about SHEs between HCPs and PWDs and their CGs, and reveal gaps in the diabetes education of PWDs and CGs.

Abstract
Numerous studies have demonstrated that use of continuous glucose monitoring (CGM) improves glycemic control and reduces diabetes-related hospitalizations and emergency room service utilization in individuals with diabetes who are treated with intensive insulin regimens. Recent studies have revealed disparities in use of CGM within racially and ethnically diverse and lower socioeconomic populations, leading to underutilization of CGM in these populations. This article reviews the scope and impact of these disparities on utilization of CGM and explores the factors that may be contributing to this issue.

Abstract
AIM Different guidelines provide similar, but not identical, therapeutic targets for HbA1c in type 2 diabetes. These targets can also depend from the different pharmacological strategies adopted for intensifying glycemic control. DATA SYNTHESIS This meta-analysis includes randomized trials adopting any pharmacological regimen for intensifying glycemic control in T2DM (versus standard of care/placebo), with a trial duration ≥2 years and a between-group HbA1c difference≥0.5%. The primary outcome was to assess the effects of the improvement of glycemic control on major cardiovascular events (MACE), ocular and renal complications, and severe hypoglycemia. Mantel-Haenszel odds ratios (MH-OR) with 95% Confidence Intervals were calculated for all the outcomes considered. We included 13 trials fulfilling the inclusion criteria. The improvement of glycemic control was associated with a lower risk of MACE (MH-OR:0.89 [95%CI 0.85-0.94]) and renal adverse events (MH-OR 0.73 [0.65-0.82]), but not all-cause mortality (MH-OR 0.95 [0.88-1.01]) and ocular adverse complications (MH-OR 0.94 [0.72-1.22]). For glucose-lowering drugs inducing hypoglycemia, a protective effect on the risk of microvascular complications, but not of MACE and all-cause mortality, was observed only for HbA1c ≤ 48 mmol/mol, but with higher risk of severe hypoglycaemia (MH-OR 2.72 [1.79-4.13]). Drugs not inducing hypoglycaemia were associated with a reduction of MACE, renal adverse events, and all-cause mortality, for HbA1c< 7% (no data for lower targets). CONCLUSIONS The present meta-analysis show that the improvement of glycemic control with drugs not inducing hypoglycemia is associated with a reduction in the risk of long-term chronic vascular and renal complications, and all-cause mortality.

Abstract
The economic and psychological consequences of diabetes-related hypoglycemic events are multifold and shared across various parties, including patients and their family or caregivers, payors, and employers. Hypoglycemic events contribute to increased morbidity, mortality, and a substantial portion of diabetes economic burden. Both severe and non-severe hypoglycemic episodes contribute to economic and psychological burden, and can have short-term consequences, such as emergency services, hospitalization, clinic visits, and increased use of diabetes supplies. Severe hypoglycemic events also generate additional follow-up costs, and are likely to occur again. Left untreated, hypoglycemia can have long-term consequences including, death, cardiovascular events, and cognitive issues. Costs vary geographically based on the treatment protocols which focus on outpatient treatment versus increased in-patient hospitalization. Certain types of medications are also associated with increased hypoglycemia, which requires closer monitoring of the patient, such as with basal insulin initiation. Some individuals with diabetes may be more vulnerable to hypoglycemia, such as the elderly, postoperative bariatric patients, and adolescent females. Measures to mitigate hypoglycemia are essential to ease the economic burden of these events. Medication management, optimal glucose control, lifestyle modifications and frequent glucose monitoring are some interventions which may help prevent hypoglycemia.

Abstract
Background The objective of this study was to describe the epidemiology of severe hypoglycaemia in Kuwait, aiming to provide a preliminary background to update the current guidelines and improve patient management. Method This was a prospective analysis of severe hypoglycaemia cases retrieved from emergency medical services (EMS) archived data between 1 January and 30 June 2020. The severe hypoglycaemia cases were then sub-grouped based on EMS personal initial management and compared in terms of scene time, transportation rate, complications and outcomes. The primary outcomes were GCS within 10–30 min and normal random blood glucose (RBS) within 10–30 min. Results A total of 167 cases met the inclusion criteria. The incidence of severe hypoglycaemia in the national EMS was 11 per 100,000. Intramuscular glucagon was used on scene in 89% of the hypoglycaemic events. Most of the severe hypoglycaemia patients regained normal GCS on scene (76.5%). When we compared the two scene management strategies for severe hypoglycaemia cases, parenteral glucose administration prolonged the on-scene time (P = .002) but was associated with more favourable scene outcomes than intramuscular glucagon, with normal GCS within 10–30 min (P = .05) and normal RBS within 10–30 min (P = .006). Conclusion: Severe hypoglycaemia is not uncommon during EMS calls. Appropriate management by EMS personals is fruitful, resulting in favourable scene outcomes and reducing the hospital transportation rate. More research should be invested in improving and structuring the prehospital management of severe hypoglycaemia. One goal is to clarify the superiority of parenteral glucose over intramuscular glucagon in the prehospital setting.

Abstract
Glucose-lowering medication and lifestyle modification are essential for optimal glycemic control in patients with type 2 diabetes mellitus (T2DM). However, glucose-lowering agents, particularly insulin and insulin secretagogues, may cause hypoglycemia, which has multiple negative effects on the cardiovascular (CV) system and may cause death. Previous studies using institutional data from the Korean Nationwide Health Insurance database have consistently found a causal relationship between severe hypoglycemia and CV outcomes and mortality. Screening for high-risk patients, appropriate management, and intensive individualized education are the most effective measures and essential for the prevention of harmful hypoglycemic events. Based on identified risk factors that predict severe hypoglycemia, we developed an 1-year risk prediction model for severe hypoglycemia that can be used in clinical settings. In this review, we describe the current understanding of severe hypoglycemia and the clinical implications in patients with T2DM. Furthermore, we highlight the importance of intensive individualized education for high-risk patients and the risk prediction model to reduce severe hypoglycemia.

Abstract
Our endocrinology practice needed to protect its highest-risk patients with type 1 diabetes (T1D) during the COVID-19 pandemic. To do so, we needed to identify these patients and develop a protocol to keep them out of the hospital (to limit risk of infection and conserve medical resources), and do so without in-person visits. So we used our peer-reviewed software, Diabetes Reporting, to identify 87 patients whose glucose management indicator (GMI) scores were over 9%. The GMI is a method for estimating the laboratory A1C using the patient's actual blood glucose measurements over the past 90 days. A GMI (or A1C) over 9% indicates a heightened risk of diabetic ketoacidosis (DKA) and, possibly, a slightly higher risk of severe hypoglycemia (SH), the two most common acute complications leading patients with T1D to be hospitalized. We contacted these 87 at-risk patients and enrolled them in a quality improvement project. This project consisted of additional online meetings with their doctors as well as weekly reports generated by Diabetes Reporting for three months, between March 28, 2020 and June 28, 2020. We hypothesized that this heightened communication would reduce the incidence of DKA and SH among the participants by reducing their GMI. As a comparison group, we used data from the T1D Exchange, which showed that, among patients with an A1C over 9%, 6.7% were hospitalized for DKA and 7% experienced SH leading to loss of consciousness in a three-month period. This led us to predict 6 incidences of DKA and 6 incidences of SH among our 87 participants during the three-month period. Instead, we saw 2 incidences of DKA and 1 incidence of SH. Moreover, the mean GMI of our participants dropped from 9.91% to 9.25%, a clinically-significant 0.66% improvement, which supports the conclusion that our protocol helped avoid acute complications among a cohort of at-risk patients with T1D by improving glycemic control during a time when we were limited to largely online care. This telemedicine protocol merits further research for its potential to improve and lower costs of care for patients with T1D, particularly for those at higher risk for acute complications.

Abstract
AIMS To investigate the association of severe hypoglycemia (SH) with all-cause mortality and complication risks among Chinese patients with type 2 diabetes mellitus (T2DM). METHODS Cohort study and nested case-control studies were conducted based on medical insurance database 2008-2015. The incidence of outcomes or the exposure of previous SH was compared among matched patients, respectively. The association between SH and outcomes was investigated and validated by different models. RESULTS Among cohort study participants (mean age of 59.0 ± 11.2 years), SH was associated with higher risk of all-cause mortality (HR = 1.80, P < 0.001) and transient ischemic attacks (TIA, HR = 1.51, P < 0.001), while no association was observed between SH and complications including myocardial infarction (MI), angina, arrhythmia and stroke. Similarly, SH was associated with about doubled all-cause mortality (OR = 1.76, P < 0.001) and TIA (OR = 2.00, P < 0.001), but not associated with risk of MI or stroke in nested case-control studies. CONCLUSIONS In Chinese patients with T2DM, SH is associated with increased risk of all-cause mortality and TIA, but no significant differences were found regard to the other examined complication risks, which need to be further explored in future studies.

Abstract
Background: This analysis from the SMILE randomized study was performed to identify predictive factors associated with the greatest reductions in hypoglycemia with the Medtronic MiniMed™ 640G Suspend before low feature in adults with type 1 diabetes at high risk of severe hypoglycemia. Methods: Clinical and treatment-related factors associated with decreased sensor hypoglycemia (SH) were identified in participants from the intervention arm by univariate and multivariate analyses. Results: The reduction in SH events <54 mg/dL (<3.0 mmol/L) in the intervention group was significantly (P < 0.0001) associated with the baseline mean number of sensor hypoglycemic events (MNSHE) <54 mg/dL. When excluding continuous glucose monitoring (CGM) factors not readily available (MNSHE, duration of SH events, area under the curve, mean amplitude of glycemic excursions), only the baseline mean time spent <54 mg/dL was found to be a significant independent predictor factor (P < 0.0001). Baseline HbA1c, mean self-monitoring of blood glucose (SMBG), and coefficient of variation of SMBG were significant, although weak, predictors in the absence of any CGM data. Conclusions: The greatest reductions in SH events achieved with the MiniMed 640G system with the Suspend before low feature were seen in participants with higher baseline MNSHE. Measuring these (usually uncollected) events can be a useful tool to predict hypoglycemia reduction. ClinicalTrials.gov Registration Identifier NCT02733991.

Abstract
Background: Developing technologies in real-time continuous glucose monitoring (CGM) are successfully reducing severe hypoglycemia (SH) in trials and clinical practice. Their impact on impaired awareness of hypoglycemia, a major risk factor for SH, is uncertain. Methods: The present study examined two scales for assessing hypoglycemia awareness status, the Gold score and the eight-item Minimally Modified Clarke Hypoglycemia Survey (MMCHS), commonly used in trials of CGM, in Portuguese-speaking adults with type 1 diabetes and conducted an exploratory factor analysis on MMCHS. Results: A bifactorial structure in MMCHS was revealed, with a clear distinction between items that measure SH experience and those that measure hypoglycemia awareness status. The latter is associated with the same risk for SH as the Gold score. Conclusions: We conclude that improvement in awareness scores by the MMCHS may reflect only a reduction in SH with no restoration of endogenous awareness, making the current literature consistent in evidence that CGM does not improve endogenous awareness and nonsensor supported protection from SH. This has implications for risk of SH when CGM is not being worn.

Abstract
Background: People with diabetes experiencing hypoglycemia are at increased risk of recurrence because of attenuated autonomic warning. We assessed the efficacy of intermittently scanned continuous glucose monitoring (isCGM; FreeStyle Libre™, Abbott) compared with usual-care self-monitoring of blood glucose (SMBG) in reducing this risk in type 1 and insulin-treated type 2 diabetes. Methods: Insulin-treated adults with diabetes and an episode of clinically significant biochemical hypoglycemia (blood glucose [BG] <3.0 mM) or symptomatic hypoglycemia and BG <4.0 mM were randomized to 6 months of isCGM (intensive group) or SMBG (control group) against a background of usual care. The primary outcome was hypoglycemia requiring second-party assistance for recovery. Prespecified secondary outcomes included other hypoglycemic episodes (self-reported, and BG <3.0, 3.0-3.9, <4.0 mM) and change in HbA1c at 24 weeks. Results: Of 59 participants (mean age 53.6 years, 44.1% males, median HbA1c 61.8 mmol/mol or 7.8%), 30 were allocated to isCGM and 29 to SMBG. The incidence of severe hypoglycemia was not significantly different between the two groups (incident rate ratio [95% confidence interval]: 1.49 [0.46-5.56], P = 0.47). The incidence of other recorded hypoglycemic episodes in the intervention group was double that in the control group (P < 0.001). There was no difference in the change in HbA1c between the two groups (P = 0.74). There were seven serious adverse events and none was considered related to the intervention. Conclusions: Although isCGM is safe, it does not appear to have a role in preventing recurrent severe hypoglycemia in at-risk individuals with diabetes.

Abstract
AIMS Severe hypoglycemia has a significant deteriorating effect on quality of life of the individual and has been associated with increased mortality. The aim of this study was to investigate the mortality among people with type 1 and type 2 diabetes suffering from severe hypoglycemia in Denmark in the last two decades. METHODS People diagnosed with type 1 (n = 44,033) and type 2 diabetes (n = 333,581) were extracted from the complete population of Denmark from 1996 to 2017 via ICD-10 diabetes codes and ATC diabetes medication codes. People suffering from severe hypoglycemia (type 1 diabetes n = 8808, type 2 diabetes n = 5605) as identified from ICD-10 codes were then matched 1:1 by year of birth, gender and year of diabetes diagnosis with those without severe hypoglycemia. Cox proportional hazards models were constructed to analyze the effect of severe hypoglycemia on mortality. RESULTS For both people with type 1 (HR 1.11, CI 95% 1.06 to 1.17) and type 2 diabetes (HR 1.77, CI 95% 1.67 to 1.87) suffering from hypoglycemia, an increased mortality risk was observed, compared to people without severe hypoglycemia. An investigation of the death causes did not indicate an association between the severe hypoglycemic episodes and death. CONCLUSION In this study, severe hypoglycemic episodes increased the mortality risk for people with type 1 and type 2 diabetes. The risk was higher among people with type 2 diabetes. Whether severe hypoglycemia is a symptom of other underlying illnesses increasing mortality risk or a risk factor itself needs further investigation.

Abstract
Although several studies have revealed that adverse cardiovascular events in diabetic patients are closely associated with severe hypoglycemia (SH), the causal relationship and related mechanisms remain unclear. This study aims to investigate whether SH promotes myocardial injury and further explores the potential mechanisms with focus on disturbances in lipid metabolism. SH promoted myocardial dysfunction and structural disorders in the diabetic mice but not in the controls. SH also enhanced the production of myocardial proinflammatory cytokines and oxidative stress. Moreover, myocardial lipid deposition developed in diabetic mice after SH, which was closely related to myocardial dysfunction and the inflammatory response. We further found that myocardial metabolic remodeling was associated with changes in PPAR-β/δ and its target molecules in diabetic mice exposed to SH. These findings demonstrate that SH exacerbates myocardial dysfunction and the inflammatory response in diabetic mice, which may be induced by myocardial metabolic remodeling via PPAR-β/δ.

Abstract
INTRODUCTION The associations of chronic kidney disease (CKD) severity, cardiovascular disease (CVD), and insulin with the risks of major adverse cardiovascular events (MACE), mortality, and severe hypoglycemia in patients with type 2 diabetes (T2D) at high cardiovascular (CV) risk are not known. This secondary, pooled analysis of data from the DEVOTE trial examined whether baseline glomerular filtration rate (GFR) categories were associated with a higher risk of these outcomes. METHODS DEVOTE was a treat-to-target, double-blind trial involving 7637 patients with T2D at high CV risk who were randomized to once-daily treatment with either insulin degludec (degludec) or insulin glargine 100 units/mL (glargine U100). Patients with estimated GFR data at baseline (n = 7522) were analyzed following stratification into four GFR categories. RESULTS The risks of MACE, CV death, and all-cause mortality increased with worsening baseline GFR category (P < 0.05), with a trend towards higher rates of severe hypoglycemia. Patients with prior CVD, CKD (estimated GFR < 60 mL/min/m2), or both were at higher risk of MACE, CV death, and all-cause mortality. Only CKD was associated with a higher rate of severe hypoglycemia, and the risk of MACE was higher in patients with CVD than in those with CKD (P = 0.0003). There were no significant interactions between randomized treatment and GFR category. CONCLUSION The risks of MACE, CV death, and all-cause mortality were higher with lower baseline GFR and with prior CVD, CKD, or both. The relative effects of degludec versus glargine U100 on outcomes were consistent across baseline GFR categories, suggesting that the lower rate of severe hypoglycemia associated with degludec use versus glargine U100 use was independent of baseline GFR category.

Abstract
PURPOSE OF REVIEW Treatment of patients with type 2 diabetes mellitus is focused on preventing the occurrence and delaying the development of macro- and micro-vascular complications. Glycemic control can help prevent these complications, but there is concern about the adverse effects of glycemia-lowering medications. A rational approach is to balance the desired low risk of adverse events against the unwanted higher risk of major complications resulting from suboptimal glucose control. RECENT FINDINGS Using the above approach, approved glucose-lowering agents have favorable benefit-to-risk profiles for use in most patients with type 2 diabetes. We first briefly review the mechanism of actions and benefits of the different commonly used classes of glycemia-lowering medications and then discuss adverse effects and safety concern associated with their use. Our overall assessment is that if used appropriately, the different classes of glycemia-lowering medications offer beneficial outcomes with relatively modest and, in some instances, preventable adverse events.

Abstract
Background Heart failure (HF) is a common cardiovascular complication of type 2 diabetes (T2D). This secondary analysis investigated baseline factors and treatment differences associated with risk of hospitalization for HF (hHF), and the possible association between severe hypoglycemia and hHF. Methods DEVOTE was a treat-to-target, double-blind cardiovascular outcomes trial in patients (n = 7637) with T2D and high cardiovascular risk randomized to insulin degludec (degludec) or insulin glargine 100 units/mL (glargine U100). The main endpoint of this secondary analysis was time to first hHF (standardized MedDRA Query definition). Severe hypoglycemia was adjudicated (American Diabetes Association definition). The main endpoint and the temporal association between severe hypoglycemia and hHF were analyzed with a Cox proportional hazards regression model. Predictors of time to first hHF were identified using baseline variables. Results Overall, 372 (4.9%) patients experienced hHF (550 events). There was no significant difference in the risk of hHF between treatments (hazard ratio [HR] 0.88 [0.72;1.08]95% CI, p = 0.227). Prior HF (HR 4.89 [3.90;6.14]95% CI, p ≤ 0.0001) was the strongest predictor of future hHF events. The risk of hHF significantly increased after (HR 2.2), and within a week after (HR 11.1), experiencing a severe hypoglycemic episode compared with before an episode. Conclusions In patients with T2D and high cardiovascular risk there were no treatment differences in terms of hHF. Prior HF was the strongest predictor of future hHF events, and there was an association between severe hypoglycemia and subsequent hHF. Further research should evaluate whether the risk of hHF can be modified by treatments aimed at reducing hypoglycemia. Trial Registration NCT01959529

Abstract
BACKGROUND We investigated the association regarding severe hypoglycemia episodes with cardiovascular disease risk and all-cause mortality in patients with type 2 diabetes. METHODS Baseline and follow-up data (n = 1,568,097) from patients with type 2 diabetes were retrieved from the National Health Insurance System database (covering the entire Korean population). Type 2 diabetes, severe hypoglycemia, and major comorbidities were identified using International Classification of Diseases 10 codes and medication information. Individuals who were classified as type 2 diabetes in the year of 2009 were screened, and we counted severe hypoglycemia episodes from 2007 to 2009. The primary outcome was newly developed myocardial infarction (MI), stroke, heart failure, or all-cause mortality. Participants were followed from the baseline index date to the date of death or until December 31, 2015. RESULTS In total, 19,660 (1.2%) patients developed at least one severe hypoglycemia event during the period from 2007 to 2009. Mean follow-up was 5.7 years. After adjustment for confounding factors, the hazard ratio (HR) of MI significantly and sequentially increased: 0 vs. 1 episode, HR 1.56, 95% CI 1.46-1.64; 0 vs. 2 episodes, HR 1.86, 95% CI 1.61-2.15; 0 vs. 3 or more episodes, HR 1.86, 95% CI 1.48-2.35, P for trend < 0.001. Similar findings were noted regarding the relationship of severe hypoglycemia episodes with stroke, heart failure, and all-cause mortality. Risks for all outcomes were highest within 1 year from the index date and showed decreasing trends with follow-up. Sensitivity analyses of the data from the subgroup population and 797,544 subjects who received a national health examination did not change the significance of the main findings. CONCLUSION Among adult Korean patients with type 2 diabetes, a severe hypoglycemia episode is associated with increased risk for cardiovascular outcomes and all-cause mortality. Significant results from dose-response, temporal, and sensitivity analyses may suggest the possibility of direct causality between severe hypoglycemia and cardiovascular outcomes and mortality.

Abstract
AIMS/INTRODUCTION The present study aimed to describe hospital utilization and examine actual medical costs for severe hypoglycemic events in patients with type 2 diabetes mellitus in Japan. MATERIALS AND METHODS Medical resource utilization associated with severe hypoglycemia was evaluated using a receipt database of acute-care hospitals in Japan. Patients with type 2 diabetes treated with antihyperglycemic agents were included. Severe hypoglycemic events were identified and divided into two groups: with or without hospitalization. Total and attributable medical costs per event were calculated based on the actual medical treatment after severe hypoglycemic events. Attributable costs were estimated from the receipt codes directly associated with the treatment of severe hypoglycemia. RESULTS In the hospitalized patients, the median length of hospital stay was 11 days, and the median total and attributable medical costs were ¥402,081 and ¥302,341, respectively. The majority of the hospitalized patients underwent a radiographic examination and general blood tests. Apart from the hospitalization costs, the costs associated with diagnosis accounted for 29.6% of the total medical costs. In the outpatients, 60.6% visited hospitals only once for the severe hypoglycemic event, whereas 11.4% visited hospitals daily for a week after the severe hypoglycemic event. The mean number of hospital visits of the outpatient after a severe hypoglycemic event was 2.7 ± 2.6 days. The median total and attributable medical costs were ¥265,432 and ¥4,628, respectively. CONCLUSIONS Significant medical resources are used for the treatment of severe hypoglycemic events of patients with type 2 diabetes in Japan.

Background The aim of the study was to investigate risk factors of hypoglycemic encephalopathy (HE) in patients with severe hypoglycemia. Methods We retrospectively enrolled patients with severe hypoglycemia who were transported to the emergency department in an ambulance. We defined severe hypoglycemia as plasma glucose level < 60 mg/dL (or capillary levels < 50 mg/dL). HE was defined as severe hypoglycemia with altered level of consciousness (Glasgow coma scale < 12) and prolonged HE as coma or stupor lasting > 24 h after glucose administration. We compared several parameters between patients with and without HE and between prolonged and recovered patients. Results Included were 173 patients with severe hypoglycemia; of them, 94 were diagnosed with HE, with 12 of them prolonged HE. Glucose level in HE patients was lower than that in those without HE (P < 0.001). Moreover, we noted a significant difference in glucose levels between the prolonged and recovered groups. Furthermore, body temperature was higher in prolonged versus recovered patients (P = 0.0017). Conclusion Blood glucose level may be correlated with severity of altered level of consciousness. In addition, body temperature may be related to coma or prolonged stupor.

Abstract
OBJECTIVE To evaluate the association of biochemical hypoglycemia with subsequent severe hypoglycemia (SH) events using the Diabetes Control and Complications Trial (DCCT) data set. RESEARCH DESIGN AND METHODS The frequency of biochemical hypoglycemia (percentage of values <70 and <54 mg/dL [3.9 and 3.0 mmol/L) was assessed using DCCT blood glucose concentrations measured at a central laboratory from seven finger-stick samples (7-point testing: pre- and 90-min postmeals and at bedtime) collected during 1 day every 3 months. SH events required a change in mental status necessitating the involvement of another individual to provide treatment. A Poisson model accounting for repeated measures from each participant was used to assess the association of biochemical hypoglycemia frequency, computed from the 7-point finger-stick data, with the development of SH events. RESULTS The risk of SH during a 3-month period was substantially higher (P < 0.001) when there was at least one hypoglycemic blood glucose value in the preceding 7-point profile, with similar results seen for both the 70 mg/dL (rate ratio = 3.0 [95% confidence interval: 2.6-3.3]) and 54 mg/dL (rate ratio = 2.7 [95% confidence interval: 2.4-3.1]) thresholds. CONCLUSIONS The occurrence of biochemical hypoglycemia <70 or <54 mg/dL is associated with an increased risk of SH. For this reason as well as the deleterious effects of hypoglycemia on glucose counter-regulation and hypoglycemia awareness, cognition, quality of life, and arrhythmias, it is important in diabetes management to avoid hypoglycemic glucose levels as much as possible.

Abstract
Background Patients with type 1 diabetes mellitus (DM) have poor glycemic control owing to extreme impairments in glucose tolerance. There are few reports regarding dental implant surgery in patients with type 1 DM. We describe herein the perioperative glycemic management in an outpatient with type 1 DM who experienced a rare case of severe hypoglycemia during dental implant surgery. Only one such case has previously been reported. Case presentation A 60-year-old male patient diagnosed with type 1 DM was scheduled for dental implant primary surgery. Premedication with peroral antibiotics was carried out to prevent possible systemic infection as a complication of DM. The patient was treated to control intraoperative hypertension with diligent attention to cardiovascular conditions by using a bolus administration of nicardipine and diltiazem. During surgery, he abruptly complained of hypoglycemic symptoms and had a blood glucose level of 32 mg/dL. Following oral administration and electrolyte-combined infusion of glucose, he immediately recovered from the critical situation. The surgical procedure, involving a lower jaw implant fixture placement, was performed as planned and resulted in less invasion, limited to the area of implant fixture placement within the right mandibular region of the two molars, compared to implant surgery that spans the entire lower jaw. Conclusions The present case suggests that it is essential to promptly monitor possible signs of hypoglycemia-precipitated acute symptoms in patients with DM. In addition, it is also necessary to appropriately administer insulin with an electrolyte-combined infusion of glucose for deliberate glycemic control; this is particularly true in patients with type 1 DM undergoing relatively highly-invasive oral surgical manipulation such as commonly performed dental implant surgery spanning the entire jaw.

Abstract
AIMS To determine if impaired awareness of hypoglycemia in patients with type 1 diabetes persists over time and to assess if continuous glucose monitoring use was associated with improved awareness of hypoglycemia in our population. METHODS Thirty-six with type 1 diabetes and impaired awareness of hypoglycemia who participated in studies on impaired awareness of hypoglycemia between 2009 and 2015 were contacted to complete an online survey. The survey included the Cox/Clarke and Gold hypoglycemia questionnaires and questions about continuous glucose monitoring use. RESULTS 23 of 36 (63%) subjects contacted completed the survey. (12 M, 11 F; median age 51 years, median diabetes duration 34 years). One had had an islet cell transplant and was excluded. Persistent impaired awareness of hypoglycemia was found in 19/22 (86%) using the Cox questionnaire and 18/22 (82%) using the Gold questionnaire. Consistent use of continuous glucose monitoring over the last six months defined as using a device ≥75% of time over the last 6 months was reported by 67% (12/18) and 68% (13/19) of participants with persistent impaired awareness of hypoglycemia as measured by Gold and Cox; respectively. Nineteen of the 22 participants (86%) reported severe hypoglycemia over the last six months. CONCLUSION Impaired awareness of hypoglycemia persisted in >80% of the subjects with type 1 diabetes we studied between 2009 and 2015. While the consistent use of continuous glucose monitoring among our participants was high; it did not translate into restoration of hypoglycemia awareness in this population. This real world data shows that severe hypoglycemia continues to be a frequent problem in this patient population.

Abstract
BACKGROUND Sensor-augmented insulin pump therapy (SAPT) with low-glucose suspend (LGS) is an effective and safe alternative for treating patients with type 1 diabetes mellitus (T1DM). New predictive low-glucose management (PLGM) systems decrease the severity and duration of hypoglycemic events. However, evidence of benefits in patients previously treated with SAPT-LGS is limited. METHODS A prospective before-after study was conducted in patients with T1DM treated with SAPT-LGS, who were switched to the Minimed® 640G system with SmartGuard® to assess the impact on A1c levels, severe hypoglycemia (SH), hypoglycemia unawareness (HU), and area under the curve (AUC) <70mg/dL after three months of follow-up. RESULTS Fifty-five patients with T1DM with a mean age of 37.9 (IQR 6, 79) years and a mean baseline A1c level of 7.52±1.11% were enrolled. After three months under PLGM, A1c levels significantly decreased to 7.18±0.91% (p=0.004). SH rate decreased from 2.47 (CI 0.44, 4.90) to 0.87 (CI 0.22, 1.52) events/patient-year (Incidence rate ratio 0.353, 95% CI 0.178, 0.637), AUC <70mg/dL decreased from 0.59±0.76 to 0.35±0.65mg/dL x minute (p=0.030). HU determined by Clarke questionnaire resolved in 23 out of 30 patients (p=0.002). CONCLUSIONS This study suggests that SAPT with PLGM decreases the frequency of SH, HU, exposure to glucose levels below 70mg/dL, and A1c levels. Based on these results, this therapy should be considered in T1DM patients previously treated with SAPT-LGS with persistent SH and HU. Further clinical trials comparing the efficacy and safety of these features are required.

Abstract
Despite great strides in pharmacotherapy for diabetes, there is increasing concern over the risk of hypoglycemia in patients with diabetes receiving pharmacotherapy as they become increasingly older. This has prompted the Japan Diabetes Society (JDS) to initiate a survey on the current status of severe hypoglycemia in clinical settings. In July 2015, following approval from the JDS Scientific Survey/Research Ethics Committee, the JDS extended an invitation to executive educators, who represented a total of 631 healthcare facilities accredited by the JDS for diabetes education, to participate in the proposed survey. Of these, those who expressed their willingness to participate in the survey were sent an application form required for obtaining ethical approval at these healthcare facilities and were then asked, following approval, to enter relevant clinical data on an unlinked, anonymous basis in a web-based registry. The current survey was fully funded by the JDS Scientific Survey/Research Committee. A case registry (clinical case database) was launched after facility-specific information (healthcare facility database) was collected from all participating facilities and after informed consent was obtained from all participating patients. With severe hypoglycemia defined as the "presence of hypoglycemic symptoms requiring assistance from another person to treat and preferably venous plasma glucose levels at onset/diagnosis of disease or at presentation clearly less than 60 mg/dL (capillary whole blood glucose, less than 50 mg/dL)", the current survey was conducted between April 1, 2014 and March 31, 2015, during which facility-specific information was collected from a total of 193 facilities with a total of 798 case reports collected from 113 facilities. Of the 193 respondent facilities, 149 reported having an emergency department as well, with the median number of patients who required emergency transportation services to reach these facilities totaling 4,962 annually, of which those with severe hypoglycemia accounted for 0.34% (17). The respondent facilities accommodated a total of 2,237 patients with severe hypoglycemia annually, with the number of patients thus accommodated being 6.5 patients per site. A total of 1,171 patients were admitted for severe hypoglycemia, with the number of patients thus admitted being 4.0 per site, who accounted for 52.3% of all patients visiting annually for severe hypoglycemia. A review of the 798 case reports collected during the survey revealed that 240, 480 and 78 patients had type 1 diabetes, type 2 diabetes, and other types of diabetes, respectively; those with type 2 diabetes were shown to be significantly older (median [interquartile range], 77.0 [68.0-83.0]) than those with type 1 diabetes (54.0 [41.0-67.0]) (P < 0.001); and the BMI was shown to be significantly higher for those with type 2 diabetes (22.0 [19.5-24.8] kg/m2 ) than for those with type 1 diabetes (21.3 [18.9-24.0] kg/m2 ) (P = 0.003). It was also found that the median estimated glomerular filtration rate (eGFR) was significantly lower among those with type 2 diabetes (50.6 mL [31.8-71.1]/min/1.73 m2 ) than among those with type 1 diabetes (73.3 [53.5-91.1] mL/min/1.73 m2 ) (P < 0.001). Again, the median HbA1c value at onset of severe hypoglycemia was shown to be 7.0 (6.3-8.1)% among all patients examined, 7.5 (6.9-8.6)% among those with type 1 diabetes, and 6.8 (6.1-7.6)% among those with type 2 diabetes, with the HbA1c value at onset of hypoglycemia being significantly lower among those with type 2 diabetes (P < 0.001). Antecedent symptoms of severe hypoglycemia were shown to be present, absent and unknown in 35.5, 35.6, and 28.9% of all patients, respectively, with the incidence of symptomatic hypoglycemia being significantly lower among those with type 1 diabetes (41.0%) than among those with type 2 diabetes (56.9%). The antidiabetic agents used in those with type 2 diabetes were insulin preparations (292 patients including 29 receiving concomitant sulfonylureas [SUs]) (60.8%), SUs (159 insulin-naïve patients) (33.1%), and no insulin preparations or SUs (29 patients) (6.0%). Of the 798 patients surveyed, 296 patients (37.2%) were shown to have required emergency transportation services for severe hypoglycemia before. Thus, the survey revealed, for the first time, the current status of treatment-related severe hypoglycemia in Japan and clearly highlights the acute need for implementing preventive measures against hypoglycemia not only through education on hypoglycemia but through optimization of antidiabetic therapy for those at high risk of severe hypoglycemia or those with a history of severe hypoglycemia.

Abstract
AIMS This study investigated the association between severe hypoglycemia (SH) and new onset atrial fibrillation (AF) and all-cause mortality in adult patients with type 2 diabetes mellitus (T2DM). METHODS Retrospective data on patients with T2DM aged between 30 and 75years who received healthcare checkups from January 1, 2005 to December 31, 2008 were analyzed using the National Health Insurance Database in Korea. The primary outcome was newly diagnosed non-valvular AF occurring after SH episode using ICD-10 codes. RESULTS Among 1,509,280 subjects, 10,864 (0.72%) patients had experienced SH events in the three years prior to health examination, and a total of 48,916 (3.24%) first-time AF episodes occurred during the follow-up period of 8.5years. The incidence of AF was significantly higher in the group with SH than the group without SH. After multivariable adjustment, previous SH was a significant risk factor for the development of AF (HR 1.10, 95% CI 1.01-1.19). All-cause mortality was also significantly increased in patients with previous SH events and prior SH with subsequent AF occurrence, compared to patients without SH events. CONCLUSIONS Prior SH events were associated with a higher risk of new onset AF and all-cause mortality in patients with T2DM.

Abstract
AIMS More than 29 million people in the US have type 2 diabetes mellitus (T2DM), a chronic metabolic disorder characterized by a progressive deterioration of glucose control, which eventually requires insulin. Abnormally low levels of blood glucose, a feared side-effect of insulin treatment, may cause severe hypoglycemia (SHO), leading to emergency department (ED) admission, hospitalization, and long-term complications; these, in turn, drive up the costs of T2DM. This study's objective was to estimate the prevalence and costs of SHO-related hospitalizations and their additional longer-term impacts on patients with T2DM using insulin. METHODS Using Truven MarketScan claims, we identified adult T2DM patients using basal and basal-bolus insulin regimens who were hospitalized for SHO (inpatient SHO patients) during 2010-2015. Two comparison groups were defined: those with outpatient SHO-related encounters only, including ED visits without hospitalization (outpatient SHO patients), and those with no SHO- or acute hyperglycemia-related events (comparison patients). Lengths of stay and SHO-related hospitalization costs were estimated, and propensity score and inverse probability weighting methods were used to adjust for baseline differences across the groups to evaluate longer-term impacts. RESULTS We identified 66,179 patients using basal and 81,876 patients using basal-bolus insulin, of which ∼1.1% (basal) to 3.2% (basal-bolus) experienced at least one SHO-related hospitalization. Among those who experienced SHO (i.e. those in the inpatient and outpatient SHO groups), 27% (basal) and 40% (basal-bolus) experienced at least one SHO-related hospitalization. One-third of basal and about one-quarter of basal-bolus patients were admitted directly to the hospital; the remainder were first assessed or treated in the ED. Inpatient SHO patients using basal insulin stayed in the hospital, including time in the ED, for 2.8 days and incurred $6896 in costs; patients using basal-bolus insulin stayed in the hospital for 2.6 days and incurred costs of $5802. Forty-to-fifty percent of inpatient SHO patients were hospitalized again for SHO. Inpatient SHO patients using basal insulin incurred significantly higher monthly costs after their initial SHO-related hospitalization than patients in the other two groups ($2935 vs $1819 and $1638), corresponding to 61% and 79% higher monthly costs; patients using basal-bolus insulin also incurred significantly higher monthly costs than patients in the other groups ($3606 vs $2731 and $2607), corresponding to 32% and 38% higher monthly costs. LIMITATIONS These analyses excluded patients who did not seek ED or hospital care when faced with SHO; events may have been miscoded; and we were not able to account for clinical characteristics associated with SHO, such as insulin dose and duration of diabetes, or unmeasured confounders. CONCLUSIONS The burden associated with SHO is not negligible. Nearly one in three patients using only basal insulin and one in four patients using basal-bolus regimens who experienced SHO were hospitalized at least once due to SHO. Not only did those patients incur the costs of their SHO hospitalization, but they also incurred at least $1,116 (62%) and $875 (70%) more per month than outpatient SHO or comparison patients. Reducing SHO events can help decrease the burden associated with SHO among patients with T2DM.

Abstract
AIMS We aimed to re-assess the previously shown but recently disputed association between HbA1c and severe hypoglycemia. METHODS 52 Patients with T1D and IAH participated in an earlier reported randomized, crossover trial with two 16-week intervention periods comparing continuous glucose monitoring (CGM) with self-monitoring of blood glucose (SMBG). In this previous study, time spent in normoglycemia (the primary outcome), was improved by 9.6% (p<0.0001). We performed post-hoc analyses using a zero-inflated Poisson regression model to assess the relationship between severe hypoglycemia and HbA1c, glucose variability and duration of diabetes. RESULTS During SMBG use, HbA1c and the number of severe hypoglycemic events were negatively associated (OR 0.20 [95% CI 0.09 to 0.44]). During CGM use, this relationship showed an odds ratio of 0.65 (95% CI 0.42 to 1.01). There was no significant relationship between glucose variability or duration of diabetes and severe hypoglycemia. CONCLUSIONS In patients with T1D and IAH, treated with standard SMBG, a negative association exists between HbA1c and the number of severe hypoglycemic events. Thus, reaching target HbA1c values still comes with a higher risk of severe hypoglycemia. CGM weakens this association, suggesting CGM enables patients to reach their target HbA1c more safely.
