Introduction:
Humulin R U-500 (U-500R) utilization has increased in the past few years, raising concerns as U-500R is indicated only for patients requiring > 200 units of insulin. Thus, evidence of dispensed total daily dose (dTDD) > 200 units of prior U-100 insulin based on pharmacy claims is increasingly used as a criterion to determine appropri...
Background
The delivery and administration of insulin has undergone many changes over the years. This research examines U.S. trends in insulin use among people with type 1 diabetes (T1D) or type 2 diabetes (T2D) in the U.S. from 2009 to 2018.

Methods
Real-world data, including baseline characteristics of people with type 2 diabetes me...
Objectives
Severely insulin-resistant Type 2 Diabetes (T2D) patients face unique treatment challenges. Humulin R U-500 (U-500R) as insulin monotherapy with both basal/bolus properties addresses these challenges but remains understudied. This retrospective study compared real-world patient characteristics, treatment patterns, and outcomes before and...
Background: Diabetes is thought to have a bi-directional relationship with mental health, including stress. Therefore, it is increasingly important to understand stress of patients with diabetes in real-time. Despite extensive use and success of RDMPs, there is limited psychometric research on the development of real-time measures of stress in the...
Introduction: There is a consistent increase in prevalence of obese type 2 diabetes (T2D) patients, many of whom require insulin treatment. As endogenous insulin secretion dwindles and progressively increasing body weight worsens insulin resistance, exogenous insulin doses can be quite high. This presents unique disease management challenges to pat...
There is a dearth of research characterizing the impact on a caregiver's sleep when caring for a minor with type 1 diabetes. This study used focus groups of people with type 1 diabetes and caregivers of minors with type 1 diabetes to explore the experience of how diabetes affects sleep. The occurrence of both unanticipated and planned sleep disrupt...
Background
Half-unit pens offer the ability to dose insulin more precisely. Information about half-unit pen use and evidence of their benefits and drawbacks is limited. This study aims to characterize people with type 1 diabetes (T1D) who have used (current/former = EVER) vs. those who have never used half-unit pens (NEVER users) and to understand...
Limited research exists regarding the burdens associated with type 1 diabetes (T1D). The study’s objective was to understand the impact of T1D from people with T1D and caregivers of minors with T1D. Six focus groups were conducted, with a total of 31 participants. Participants included people with T1D, ages 23 to 72 (n = 17) and caregivers ages 34...
Human regular U-500 insulin (U-500R) provides both basal and prandial coverage to people with diabetes. As part of VIVID study, we studied patient-reported outcomes (PRO) of U-500R delivered by multiple daily injections (MDI, n = 211) and continuous subcutaneous infusion using a novel U-500R pump (CSII, n = 209). Treatment-Related Impact Measure fo...

Objective:
To understand patient characteristics, dosing, adherence, and persistence related to high-dose insulin therapy.
Methods:
This was a retrospective obs...
Fear of hypoglycemia (FoH) contributes to poor behavioral and glycemic outcomes. The ADA position statement on psychosocial care for people with diabetes recommends screening for FoH, with referral if positive. A clinically useful screener for FoH does not exist, hindering further actions by clinicians to address FoH in their patients. As part of a...

Methods: The IBM® MarketScan® Commercial and Medicare databases were used to identify trends for insulin use over 9 years among people with T1D or T2D who filled a prescr...
Introduction: U-500 regular insulin (U-500R) was developed to help severely insulin-resistant patients meet high insulin requirements (>200 units/day). Here, we described in real-world setting a patient cohort using ≤200 units/day of standard concentration insulin or non-U500R concentrated insulin per pharmacy claims, who were then transitioned to...
Background: Many validated patient-reported outcome measures (PROMs) evaluate activation, behaviors, and attitudes towards managing one’s own health and care. However, their association with utilization of diabetes management technology and glycemic control has not been well studied.
Methods: People participating in Livongo’s RDMP for 12-18 months...
OBJECTIVE | Human regular U-500 insulin (U-500R) is concentrated insulin with basal and prandial activity that can be used as insulin monotherapy. The goal of this study was to better understand treatment patterns (total daily dose [TDD] and concomitant medications), adherence, and persistence in real-world patients treated with U-500R.
DESIGN AND...
Objective:
In people with diabetes requiring high dose insulin, U-500R can provide both basal and prandial insulin coverage by multiple daily injection (MDI), but there are limited data on U-500R by continuous subcutaneous insulin infusion (CSII). We compared safety and efficacy of U500-R delivered by a novel, specifically-designed U500-R insulin...
Fear of hypoglycemia (FoH) has been associated with suboptimal diabetes management and health outcomes. The American Diabetes Association recommends further mental health evaluation and treatment if a person with diabetes has a positive screen for FoH. This study investigated factors associated with behavioral and emotional aspects of FoH among adu...
People with type 1 diabetes (T1D) and caregivers of minors with T1D experience significant impact to many aspects of daily life. The impact of diabetes is not limited to monetary costs assessed by healthcare and economic data, but also includes the “cost” of sacrifices, such as sleep disruption and time lost. Limited research exists regarding daily...
Introduction: Human regular U-500 insulin (U-500R) improves glycemic control in people with type 2 diabetes (PwT2D) inadequately controlled with high doses of other insulins. Limited evidence exists on treatment patterns and outcomes in PwT2D who initiate U-500R using a U-500R KwikPen (U500KP) in the real-world setting.
Methods: Adults with ≥2 clai...
Aims
To describe global patterns of insulin treatment and to assess impact of patient, provider, health system, and economic influences on treatment decisions for patients with insulin‐treated type 2 diabetes (T2D).

One hundred current multiple daily injection (MDI) users, including 31 former pump users, and 250 current pump users were recruited from myGlu.org, and 61 healthcare providers were recruited from T1D Exchange Clinic Netwo...
Glycemic Variability (GV) and Treatment Satisfaction (TS) are not accurately reflected in HbA1c. This study explored GV measures and their effect on insulin TS, productivity and activity in a real-world population with T1D. This prospective survey was of 98 adults from the T1D Exchange online patient community. Surveys were completed and CGM data w...
People with type 1 diabetes (PWD) that strive for lower glucose targets are in need of more precise dosing and may require smaller insulin dose adjustments. Most currently available pens deliver insulin in one unit (U) increments, and few deliver half (0.5) U. There is a need to better understand who is using half unit pens (HUP) and their potentia...
Background: Basal insulin peglispro (BIL) has a peripheral-to-hepatic distribution of action that resembles endogenous insulin and a prolonged duration of action with a flat pharmacokinetic/pharmacodynamic profile at steady state, characteristics that tend to reduce hypoglycemia risk compared to insulin glargine (GL). The primary objective was to d...

... Since 2012, there have been important advances in the number of pharmacologic agents for treating diabetes in the outpatient setting, as well as advances in available technologies for monitoring therapy (14)(15)(16). Several important studies have been published in the past decade that address issues for which there was little data to support recommendations provided in the earlier guideline. ...
... Regular human insulin U500 is the only highly concentrated insulin that is currently available. A clinically meaningful decrease in HbA 1c has been demonstrated in retrospective analysis of realworld data (23)(24)(25)(26). This was attributed to the easier titration to the needed dose without the need for dose splitting, which in turn improved treatment adherence. ...
... Research evidence on coping efforts can broadly be categorised into positive/productive and negative/nonproductive efforts. Depending on the stressor, productive coping mechanisms usually include psychological optimism, planning, and social support [15,16]. Negative coping approaches include persistent non-productive habit formation, spirituality, use of herbal medicine, logistic constraints, behavioural disengagement, and poorer adherence to diabetes regimen [6,7,17]. ...
... Although this compromised lung function has been reported, there is still not enough data to substantiate the claims. In a clinical trial, cases of developing lung cancer (squamous lung cancer) in both smokers and non-smokers have been reported [83]. These observations could be attributed to the growth factor properties of insulin. ...
... Glucagon is an effective treatment for severe hypoglycemic events [4], but studies show that glucagon usage remains low [10,11]. Low usage may be in part because of the perceived difficulty in administering traditional injectable glucagon-which was the only approved treatment until 2019 [12][13][14][15][16][17]. While designated caregivers themselves may know how and be confident enough to use an emergency injectable glucagon kit (e-kit), other people PWD may rely on, such as grandparents or friends, may not. ...
... Among diabetes-related anxieties, fear of hypoglycemia (FoH) is defined as an 'extreme worry or anxiety about low blood glucose and its consequences' is prevalent in people with diabetes [3]. It has a significant impact on individuals' quality of life, psychological state, and management of disease [4][5][6][7]. The American Diabetes Association's (ADA) position statement on psychosocial care emphasizes the need for screening for FoH using standardized and validated tools [1]. ...
... The superior insulin exposure and action of AT278 U500 within the first 30 and 60 min postdose suggest that AT278 U500 will enable dosing at meal or even after meal without compromising postprandial glucose control and will thus provide more flexibility with meals and daily schedule for people with high insulin needs. Although none of the concentrated insulins are approved for insulin pump therapy yet, several studies have reported the safe, effective, and more convenient use of concentrated insulins in insulin pumps (30)(31)(32). As more highly concentrated insulins become available, it is anticipated that smaller pumps will follow, which could further relieve the daily burden of managing diabetes. ...
... Provider override and advance provision for exceptional requirements should remain options under any set of algorithm rules. 16 In this report of a noncomputerized system, exploratory findings in our population suggest that an excess of hypoglycemia may be associated with use of peak insulin infusion rate ‡12.2 units/h. ...
... Two validated questionnaires, Diabetes Empowerment Scale Short Form (DES-SF), which is a measure of diabetes-related psychosocial self-efficacy, and Motivations and Attitudes Toward Changing Health (MATCH), can provide insight into an individual's self-reported empowerment and motivation [28,29]. The DES-SF has been used in cross-sectional surveys and clinical studies to measure the impact of interventions on diabetes empowerment [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45]. While DES-SF is specific to diabetes, MATCH is designed to assess general attitudes towards changing health behaviors, regardless of clinical condition [28,29]. ...
... These instruments are validated for use in people with diabetes and have been used in the research setting for decades. 8 However, they are not routinely used by healthcare providers (HCPs) for screening in clinical practice. 8 9 A recent systematic review reported that existing FoH instruments lack clear cut-off values informing clinical action. ...
