Abstract
The growing prevalence of type 2 diabetes (T2D) remains a leading health concern in the US. Despite new medications and technologies, glycemic control in this population remains suboptimal, which increases the risk of poor outcomes, increased healthcare resource utilization, and associated costs. This article reviews the clinical and economic impacts of suboptimal glycemic control in patients on basal-bolus insulin or multiple daily injections (MDI) and discusses how new technologies, such as tubeless insulin delivery devices, referred to as "patch pumps", have the potential to improve outcomes in patients with T2D.

Should people with type 2 diabetes treated by multiple daily insulin injections with home health care support be switched to hybrid closed-loop? The CLOSE AP+ randomized controlled trial. Diabetes Obes Metab 2024; 26:622-630. [PMID: 37921083 DOI: 10.1111/dom.15351] [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: 09/19/2023] [Revised: 10/15/2023] [Accepted: 10/15/2023] [Indexed: 11/04/2023]
Abstract
AIM The study aim was to evaluate the feasibility, safety and efficacy of automated insulin delivery (AID) assisted by home health care (HHC) services in people with type 2 diabetes unable to manage multiple daily insulin injections (MDI) at home on their own. PATIENTS AND METHODS This was an open label, multicentre, randomized, parallel group trial. In total, 30 adults with type 2 diabetes using MDI and requiring nursing support were randomly allocated to AID or kept their usual therapy over a 12-week period. Both treatments were managed with the support of HHC services. The primary outcome was the percentage time in the target glucose range of 70-180 mg/dl (TIR). Secondary outcomes included other continuous glucose monitoring metrics, glycated haemoglobin (HbA1c) levels, daily insulin doses, body weight, and of quality of life scores, fear of hypoglycaemia and satisfaction questionnaires. RESULTS Age (69.7 vs. 69.3 years) and HbA1c (9.25 vs. 9.0) did not differ in MDI and AID at baseline. Compared with MDI, AID resulted in a significant increase in TIR by 27.4% [95% CI (15.0-39.8); p < .001], a decrease in time above range by 27.7% and an unchanged time below range of <1%. A between-group difference in HbA1c was 1.3% favouring AID. Neither severe hypoglycaemia nor ketoacidosis occurred in either group. Patient and caregiver satisfaction with AID was high. CONCLUSIONS AID combined with tailored HHC services significantly improved glycaemic control with no safety issues in people with type 2 diabetes previously under an MDI regimen with HHC. AID should be considered a safe option in these people when lacking acceptable glucose control.

Abstract
Insulin therapy is the mainstay to treat diabetes characterizedd by hyperglycemia. However, its short half-life of only 4-6 min limits its effectiveness in treating chronic diabetes. Advances in recombinant DNA technology and protein engineering have led to several insulin analogue products that have up to 42 h of glycemic control. However, these insulin analogues still require once- or twice-daily injections for optimal glycemic control and have poor patient compliance and adherence issues. To achieve insulin release for more than one day, different injectable delivery systems including microspheres, in situ forming depots, nanoparticles and composite systems have been developed. Several of these delivery systems have advanced to clinical trials for once-weekly insulin injection. This review comprehensively summarizes the developments of injectable insulin analogs and delivery systems covering the whole field of injectable long-lasting insulin technologies from prototype design, preclinical studies, clinical trials to marketed products for the treatment of diabetes.

Abstract
BACKGROUND More than 35 million Americans live with type 2 diabetes (T2D), resulting in the need for newer strategies and technologies to manage the disease. Insulin pump therapy (IPT) has historically been reserved for type 1 diabetes, although emerging data demonstrates improved glucose outcomes for patients with T2D using IPT. PURPOSE To measure the change in HgbA1c in patients with T2D after changing therapy from multiple daily injections (MDI) to continuous subcutaneous insulin infusion through IPT. METHODOLOGY A retrospective comparison study was conducted by reviewing the electronic medical record of patients with T2D, older than 18 years, who had been on multiple daily insulin injections for at least 1 year, followed by IPT for at least 1 year. RESULTS One hundred seventy-one patients met the inclusion criteria. There was a statistically significant reduction in mean HgbA1c from 9.6% to 7.6%. CONCLUSION Insulin pump therapy may result in lower HgbA1c levels for T2D not at goal on MDI. IMPLICATIONS Patients on multiple daily insulin injections who are not at goal should be considered for IPT.

Abstract
Background Hyperglycemia is common and difficult to control in perioperative patients with type 2 diabetes mellitus (T2DM), which impacts their prognosis after operation. Our study investigated the short-term effect of continuous subcutaneous insulin infusion (CSII) and multiple daily injection (MDI) in perioperative T2DM patients using the data envelopment analysis (DEA). Methods T2DM patients (n = 639) who underwent surgeries in Guangdong Provincial Hospital of Traditional Chinese Medicine (2009.01-2017.12) were included. Insulin was provided to each patient during the study and separated into a CSII group (n = 369) and an MDI group (n = 270). DEA was performed to compare the therapeutic indexes and investigate the short-term effect of the CSII group and MDI group. Results Scale efficiencies of the CSII group with CCR model and BCC model were better than that of the MDI group. Regarding slack variables, with higher surgical levels, the CSII group was closer to the ideal state than the MDI group, which indicated in improving the average fasting blood glucose (AFBG), antibiotic use days (AUD), preoperative blood glucose control time (PBGCT), first postoperative day fasting blood glucose (FPDFBG), and postoperative hospitalization days (PHD). Conclusion CSII could effectively control blood glucose levels and shorten perioperative hospitalizing time for T2DM patients, indicating that CSII was beneficial in perioperative period and should be promoted clinically.

Abstract
Objective: To explore the clinical consequences and potential root causes of insulin pump-associated adverse events (AEs) reported in the Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database. Research Design and Methods: Qualitative template analysis of narrative data in a 20% stratified random sample (n = 2429) of reported AEs that occurred during the first 6 months of 2020 involving five insulin pump models marketed at that time: (1) MiniMed™ 670G, (2) MiniMed™ 630G, (3) Omnipod®, (4) Omnipod DASH®, and (5) t:slim X2™. Results: Of the 2429 AEs, 92% included a clinical consequence in the narrative description, with critical hyperglycemia (i.e., blood glucose [BG] >400 mg/dL; 47%) and critical hypoglycemia (i.e., BG <54 mg/dL; 24%) being the most common consequence cited. Only 50% of the AE narratives included information to support the identification of a root cause. The most cited root cause informing remarks were issues with the pump or pod reservoir/cartridge (9%), the occurrence of an obstruction of flow alarm (8%), and problems with the infusion set or site (8%). Some clinical consequences and root cause informing remarks were cited more frequently in AE narratives involving specific insulin pump models, but manufacturer variability in the amount and type of information reported may have affected these findings. Conclusions: Our findings show general themes found in insulin pump-associated AE that providers can use to raise patient awareness of potential risks associated with insulin pump use and develop strategies to prevent future AEs. Improvements in AE investigation and reporting processes are still necessary.

Abstract
Background: The Tandem Control-IQ (CIQ) system has demonstrated significant glycemic improvements in large randomized controlled and real-world trials. Use of this system is lower in people with type 1 diabetes (T1D) government-sponsored insurance and those with type 2 diabetes (T2D). This analysis aimed to evaluate the performance of CIQ in these groups. Methods and Materials: A retrospective analysis of CIQ users was performed. Users age ≥6 years with a t:slim X2 Pump and >30 days of continuous glucose monitoring (CGM) data pre-CIQ and >30 days post-CIQ technology initiation were included. Results: A total of 4243 Medicare and 1332 Medicaid CIQ users were analyzed among whom 5075 had T1D and 500 had T2D. After starting CIQ, the Medicare beneficiaries group saw significant improvement in time in target range 70-180 mg/dL (TIR; 64% vs. 74%; P < 0.0001), glucose management index (GMI; 7.3% vs. 7.0%; P < 0.0001), and the percentage of users meeting American Diabetes Association (ADA) CGM Glucometrics Guidelines (12.8% vs. 26.3%; P < 0.0001). The Medicaid group also saw significant improvement in TIR (46% vs. 60%; P < 0.0001), GMI (7.9% vs. 7.5%; P < 0.0001), and percentage meeting ADA guidelines (5.7% vs. 13.4%; P < 0.0001). Patients with T2D and either insurance saw significant glycemic improvements. Conclusions: The CIQ system was effective in the Medicare and Medicaid groups in improving glycemic control. The T2D subgroup also demonstrated improved glycemic control with CIQ use. Glucometrics achieved in this analysis are comparable with those seen in previous randomized controlled clinical trials with the CIQ system.

Abstract
BACKGROUND To evaluate the impact of switching from U-100 to U-500 insulin in patients with type 2 diabetes mellitus (T2DM) uncontrolled with continuous subcutaneous insulin infusion (CSII) by pump. METHODS We retrospectively collected data from patients with T2DM, treated by U-100 CSII, who were switched to U-500 regular insulin where haemoglobin A1c (HbA1c) was >8% and/or insulin total daily dose (TDD) was >100 UI/d. Data collection from patient medical records included HbA1c, lipid levels, liver biomarkers, weight, TDD, declared hypoglycaemic episodes and measured by continuous glucose monitoring (CGM). RESULTS Sixty-five patients were included, aged 63.9 ± 8.6 years, insulin pump since 3.7 ± 3 years, TDD 186 ± 52 U/day, body mass index 39.4 ± 5.3 kg/m², HbA1c 9.03 ± 1.6%. After switching to U-500 insulin, HbA1c dropped by -0.96% (P < 0.0001) at one year with the effect maintained at three years (- 0.95%, P < 0.01). A subgroup analysis (n=42/65) using a severity score which covered the three previous years on U-100 and the next three years on U-500 insulin confirmed the latter's efficacy. Body weight increased by + 4.8 kg and TDD by 16% at three years. Declared non-severe hypoglycaemia increased significantly three- to four-fold during follow up, but % time-below-range at six months did not differ between the two treatments. Baseline HbA1c correlated with improved glucose control with U-500. CONCLUSIONS U-100 to U-500 insulin switch improves glucose control in CSII T2DM patients, especially with high baseline HbA1c. Use of concentrated insulin in pumps may represent an advance in the strategy for treating T2DM insulin resistant states with uncontrolled hyperglycaemia after a switch from multiple daily injections to pump therapy.

Abstract
Numerous studies have demonstrated the clinical value and safety of insulin pump therapy in type 1 diabetes and type 2 diabetes populations. However, the eligibility criteria for insulin pump coverage required by the Centers for Medicare & Medicaid Services (CMS) discount conclusive evidence that supports insulin pump use in diabetes populations that are currently deemed ineligible. This article discusses the limitations and inconsistencies of the insulin pump eligibility criteria relative to current scientific evidence and proposes workable solutions to address this issue and improve the safety and care of all individuals with diabetes.

Abstract
An increasing number of patients with type 2 diabetes mellitus (T2DM) use insulin pumps. The first insulin pumps especially designed for patients with T2DM have recently become available. However, national guidelines do not primarily recommend the use of continuous subcutaneous insulin infusion (CSII) for this patient group. The effectiveness of CSII in T2DM has not yet been convincingly demonstrated, despite some positive evidence. An overview and an assessment of various studies to date will be given. T2DM is a heterogeneous disease with a substantial phenotypic variability; therefore, it is difficult to provide general conclusions about the effectiveness of CSII in T2DM therapy. The pump types, characteristics, and associated barriers may play a relevant role for therapy outcome. Most advanced functions like various bolus dosages offered by conventional insulin pumps are not needed for T2DM treatment and complicate the device handling for this subject group. Additionally, new technologies like increased connectivity, advanced software features, and interoperability are currently becoming available representing further barriers. The implementation of this technological progress might be a benefit for pumps for T2DM as well. However, these have not been sufficiently examined either and increased security challenges due to integrated peripheral components should not be neglected in terms of a sound cybersecurity. Pump features and handling for patients with T2DM should be as easy as possible, indicating a need for insulin pumps specially designed for patients with T2DM. However, it has to be investigated if pumps designed for T2DM are more effective than other intensified insulin regimens.

American Association of Clinical Endocrinology Clinical Practice Guideline: The Use of Advanced Technology in the Management of Persons With Diabetes Mellitus. Endocr Pract 2021; 27:505-537. [PMID: 34116789 DOI: 10.1016/j.eprac.2021.04.008] [Citation(s) in RCA: 121] [Impact Index Per Article: 40.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Revised: 04/16/2021] [Accepted: 04/19/2021] [Indexed: 02/08/2023]
Abstract
OBJECTIVE To provide evidence-based recommendations regarding the use of advanced technology in the management of persons with diabetes mellitus to clinicians, diabetes-care teams, health care professionals, and other stakeholders. METHODS The American Association of Clinical Endocrinology (AACE) conducted literature searches for relevant articles published from 2012 to 2021. A task force of medical experts developed evidence-based guideline recommendations based on a review of clinical evidence, expertise, and informal consensus, according to established AACE protocol for guideline development. MAIN OUTCOME MEASURES Primary outcomes of interest included hemoglobin A1C, rates and severity of hypoglycemia, time in range, time above range, and time below range. RESULTS This guideline includes 37 evidence-based clinical practice recommendations for advanced diabetes technology and contains 357 citations that inform the evidence base. RECOMMENDATIONS Evidence-based recommendations were developed regarding the efficacy and safety of devices for the management of persons with diabetes mellitus, metrics used to aide with the assessment of advanced diabetes technology, and standards for the implementation of this technology. CONCLUSIONS Advanced diabetes technology can assist persons with diabetes to safely and effectively achieve glycemic targets, improve quality of life, add greater convenience, potentially reduce burden of care, and offer a personalized approach to self-management. Furthermore, diabetes technology can improve the efficiency and effectiveness of clinical decision-making. Successful integration of these technologies into care requires knowledge about the functionality of devices in this rapidly changing field. This information will allow health care professionals to provide necessary education and training to persons accessing these treatments and have the required expertise to interpret data and make appropriate treatment adjustments.

Abstract
AIMS To compare glycemic outcomes in adults with type 2 diabetes mellitus (T2DM) before and 90 days after initiating Omnipod® or Omnipod DASH® Insulin Management Systems. METHODS In this retrospective observational study (N = 3,592) change in HbA1c level, total daily dose (TDD) of insulin (n = 3,053), and frequency of self-reported hypoglycemic events (HE, <70 mg/dL, n = 2,922) were assessed overall and by prior treatment modality (multiple daily injections (MDI) or continuous subcutaneous insulin infusion (CSII)), age group, and baseline HbA1c category. RESULTS Change (mean ± SD) in HbA1c was -1.3 ± 1.7% [-14 ± 19 mmol/mol] overall, -1.4 ± 1.7% [-15 ± 19 mmol/mol] for prior MDI users, and -0.9 ± 1.5% [-10 ± 16 mmol/mol] for prior CSII users (p<0.0001). The percentage of patients with HbA1c ≥9% [≥75 mmol/mol] decreased (49% to 19%), and with HbA1c <7% [<53 mmol/mol] increased (10% to 22%) (p<0.0001). Prior therapy, age, and baseline HbA1c category were factors affecting change in HbA1c (p<0.05). Reductions in TDD (overall, -33 ± 52U, p<0.0001) and HE per week (overall, -0.5 ± 2.0, p<0.0001), were seen regardless of prior treatment, age, or baseline HbA1c. CONCLUSIONS Omnipod System use was associated with statistically and clinically meaningful reductions in HbA1c, TDD, and HE compared to prior treatments in T2DM.

Abstract
Technology in diabetes is rapidly evolving, with the aim of helping affected people to safely optimize their blood glucose control. New technologies are now considered as an essential tool for managing glycemia predominantly in people with type 1 diabetes, and clinical trials have demonstrated that in these subjects the use of continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM) systems are associated with improved glycemic control along with a better quality of life. Literature regarding technologies and type 2 diabetes is relatively lacking, but innovations may have an important role also in the management of these patients. Some studies in adults with type 2 diabetes have shown benefits with the use of CGM in terms of glycemic variability and improved therapeutic adjustments. Clinical trials about CSII and CGM use in type 2 diabetes may have some pitfalls and future studies are needed to assess how these advanced systems could improve clinical outcomes and also ensure cost-effectiveness in this population. In this narrative review, we aim to highlight the most relevant studies on this topic and to focus on the potential role of new technological devices in type 2 diabetes management.

Abstract
Background: This study undertook to assess usability, 24-h glycemic profiles, and safety of an investigational basal/bolus insulin delivery device (IDD) providing rapid-acting or regular human insulin (RHI) for people with type 2 diabetes (T2D) transitioning from multiple daily insulin injections (MDIs). Methods: This prospective, single-center, open-label two-period study enrolled adults with T2D and glycated hemoglobin (HbA1c) 7%-11% (53-97 mmol/M). Participants continued the usual MDI therapy during a 2- to 3-day in-clinic MDI period and then within 7 days were switched to the IDD, using current insulin dose, for a 6-day in-clinic IDD period, with blinded continuous glucose monitoring throughout the in-clinic periods. Results: We enrolled 21 participants (mean ± standard deviation age 57 ± 8 years; HbA1c 8.2% ± 0.9% [66 ± 9.8 mmol/M]) using U-100 insulin lispro (n = 11) or who switched to U-100 RHI (n = 10). Glycemic measures improved from the MDI to IDD period, including fasting blood glucose (BG), 141.2 ± 38.3 mg/dL (7.8 ± 2.1 mmol/L) versus 121.2 ± 35.0 mg/dL (6.7 ± 1.9 mmol/L; P = 0.002), respectively; 24-h mean BG, 137.0 ± 20.5 mg/dL (7.6 ± 1.1 mmol/L) versus 125.0 ± 16.5 mg/dL (6.9 ± 0.9 mmol/L; P = 0.004); and time in range (at 70-180 mg/dL; 3.9-10 mmol/L), 81.0% ± 14.4% versus 87.5% ± 10.6% (P = 0.008). No significant differences between MDIs and IDD use were recorded for time <70 mg/dL (1.6% ± 2.7% vs. 3.1% ± 2.7%, P = 0.08), CV%, or mean of daily differences. Mean amplitude of glycemic excursions was significantly lower with the IDD (P = 0.011). There were no significant differences between insulin lispro and RHI for any glycemic measure. No serious adverse events were recorded. Conclusions: In the context of this exploratory study, the IDD was safe and effective to administer insulin lispro and RHI for adults with T2D.

Abstract
Due to the progressive nature of type 2 diabetes (T2DM), initiation of insulin therapy is very likely in the disease continuum. This article aims at highlighting the current situation with regard to insulin therapy in people with T2DM in Europe and at presenting the associated unmet need. Challenges for both people with T2DM and healthcare professionals include clinical inertia also derived from fear of hypoglycaemia, weight gain and injections as well as increased need for a comprehensive diabetes management. We compare national and international guidelines and recommendations for the initiation and intensification of insulin therapy with the real-world situation in six European countries, demonstrating that glycaemic targets are only met in a minority of people with T2DM on insulin therapy. Furthermore, this work evaluates currently recorded numbers of people with T2DM treated with insulin in Europe, the proportion not achieving the stated glycaemic targets and thus in need to enhance insulin therapy e.g. by a change in means of insulin delivery including, but not limited to, insulin pens, wearable mealtime insulin delivery patches, patch pumps, and conventional insulin pumps with continuous subcutaneous insulin infusion.

Abstract
An online survey was conducted to assess the perspectives and use of diabetes technologies by a sample of U.S. primary care physicians (PCPs) and endocrinologists to optimize intensive insulin therapy in patients with type 2 diabetes. Overall, endocrinologists reported using diabetes technologies more frequently than PCPs for patients with type 2 diabetes requiring basal-bolus insulin therapy. PCPs and endocrinologists who were highly focused on diabetes management with insulin therapy reported using insulin delivery devices (insulin pumps and wearable tube-free patches) when patients are not achieving their A1C target while taking basal plus three or more prandial injections of insulin daily.

Abstract
This article reports on a survey conducted at four diabetes-related annual conferences in 2017 and 2018 to obtain input from the medical community regarding the most important features of insulin delivery devices to address the unmet needs of people with type 2 diabetes who require basal/bolus insulin therapy. The overall patterns of responses compiled from 742 participating health care providers, each voting for three of eight proposed features of insulin delivery devices, were mostly similar numerically at each conference. The features garnering the top three percentages of votes (n = 2,226) averaged for all four conferences were tube-free patch (14.7%), reduced number of insulin injections (14.7%), and dose capture report (14.2%). Four other features received almost as many votes: flexible dosing (14.0%), patient lifestyle app (13.3%), wireless controller (12.7%), and interconnected glucose monitoring (12.6%). This survey provided valuable information that can aid the development of future insulin delivery devices.

Abstract
PURPOSE OF REVIEW The increasing prevalence of type 2 diabetes is driving the boundaries of clinical diabetes care outside of the traditional office setting. The purpose of this paper will be to review recent technological advances in the medical management of people with type 2 diabetes, spanning the spectrum of care from access to healthcare providers/educators, to continual virtual support methods, on-line management tools, and technologically integrated medication delivery systems. RECENT FINDINGS Recent findings support a potential positive impact of technology on access to care, clinical outcomes, convenience, patient well-being, and patient acceptance. This includes the use of Bluetooth-enabled glucose meters, continuous glucose monitors, mHealth apps, smartpens, and insulin pumps. However, there are impediments to the implementation of some technologies due to cost and lack of insurance coverage. There is evidence to support the use of technology to improve the management and treatment of people with type 2 diabetes. Further research is required to demonstrate the long-term clinical benefit and financial viability of technology in the management of type 2 diabetes.

Abstract
Continuous subcutaneous insulin infusion (CSII) is a widely used treatment for diabetes patients. Insulin infusion sets (CSII-catheters) are continuously optimized regarding size, handling and safety, but recurring dysfunction (kinking or occlusion), due to different user situations, behavior or chain of events, demand new ways to improve the functionality and safety in patients experiencing these issues. A novel CSII-catheter design (Lantern) features additional lateral perforations, which guarantee functionality even in case of kinking or occlusion. This study aimed to compare functionality, insulin distribution, and failure rate of Lantern and standard catheters using excised human adipose tissue samples. Novel Lantern CSII-catheters (open and artificially occluded) and commercially available standard CSII-catheters were inserted into adipose tissue samples. A mixture of insulin and contrast agent was infused as single bolus (7 IU) with an insulin infusion pump at highest flow rate (1 IU/s). Microtomography images and surface-to-volume ratios were used to assess insulin distribution and depot volume indicating the functionality of CSII-catheters. Failure rate was measured by flow-stop alerts of the pump. We found no difference in the volume of insulin depots compared with the nominal volume of 70 μL. Surface-to-volume ratios showed no significant difference among CSII-catheters. None of the catheters triggered any flow-stop alarm. The novel Lantern CSII-catheter design achieved similar insulin distribution as commercially available CSII-catheters. Moreover, functionality of Lantern CSII-catheters was guaranteed during occlusion, which is an improvement compared with standard CSII-catheters. We conclude that the novel CSII-catheter design has the potential to provide a valuable contribution to patient well-being and safety.

Abstract
Purpose: To examine the perceptions, proficiencies, and barriers of diabetes device use among rural clinic providers. Methods: A total of 210 surveys were sent through e-mail and/or U.S. Postal Service to rural clinics throughout Alaska, Idaho, Montana, Oregon, Washington, and Utah based on discussions with rural clinic network leadership in the states. Responses were included if the participant was 18 years of age and older, and worked at a rural clinic as a physician, physician assistant, nurse, nurse practitioner, allied health worker, or clinic manager. Results: Respondents included clinic management (13%), midlevel providers (physician assistants and nurse practitioners) and allied health workers (pharmacists, dietitians, and social workers, 30.8%), nurses (30.8%), and physicians (23.1%). We had a low response rate (20%; n = 41), but of those who said they work with patients who have diabetes, only 47.4% indicated that they use diabetes devices as part of their patients' treatment. The most common barrier reported among respondents suggested that additional medical team expertise is needed in their community or clinic to adopt insulin pumps and/or continuous glucose monitoring for qualified patients (75.9% and 80.8%, respectively). Conclusion: Lack of provider experience and having patients managed by out-of-area experts were the biggest reasons for providers not seeing or managing patients using these devices. Lack of provider access, patient satisfaction with current diabetes regimens, unsupportive health care team, patient literacy, and patient fear showed limited to negligible endorsements from survey respondents. A variety of potential solutions to this problem of limited provider experience and training are also offered.

Abstract
BACKGROUND Persistence with multiple daily insulin injections (MDI) may be challenging for patients with type 2 diabetes (T2DM). However, limited information is available regarding the effect of persistence with MDI on outcomes. OBJECTIVE To evaluate persistence with basal and bolus insulin therapy and assess its relationship with clinical and economic outcomes in a real-world setting. METHODS This retrospective matched cohort study used 2012-2015 data from multiple U.S. commercial health plans (IBM MarketScan). Patients with T2DM aged 18-64 years with ≥ 2 basal and ≥ 2 bolus insulin claims during a 12-month period were eligible for inclusion if they had 18 months of continuous health plan enrollment (6-month baseline and 12-month post-index). Persistence during 12 months post-index was defined using 2 methods: (a) method 1, ≤ 90-day gaps in both basal and bolus insulin claims and (b) method 2, ≥ 1 basal and ≥ 1 bolus insulin claim every quarter (every 90 days) for 4 consecutive quarters after index bolus claim. Propensity score matching was used to match persistent and nonpersistent method 2 cohorts. Mean per-patient all-cause and diabetes-related medical costs (2015 U.S. dollars, excluding outpatient drugs) and health care resource use (HCRU) were calculated. For patients with hemoglobin A1c (A1c) values during baseline and post-index months 10-12, treatment success was defined as (a) A1c decrease from baseline of ≥ 1% and/or (b) baseline A1c ≥ 7% with post-index A1c < 7%. Baseline characteristics of matched cohorts were compared using standardized mean differences (SMDs). Outcome variables were compared using t-tests, chi-square tests, and generalized linear models. RESULTS Characteristics of 12,882 eligible patients and 12-month persistence rates were similar as defined by method 1 (22.4%) and method 2 (21.1%). After matching, the method 2 cohorts included 2,723 and 8,169 persistent and nonpersistent patients, respectively, with well-balanced baseline characteristics (mean age 53 years; 58% men; all SMDs < 0.1). All-cause annual medical costs were lower for the persistent cohort (mean $13,499 vs. $17,362; P < 0.0001), as were annual diabetes-related costs (mean $6,392 vs. $8,376; P < 0.0001). In persistent versus nonpersistent cohorts, 11% versus 15% of patients, respectively, experienced ≥ 1 hospitalization; 21% versus 24%, respectively, had ≥ 1 ED visit; 9% versus 12%, respectively, experienced ≥ 1 diabetes-related hospitalization; and 13% versus 15%, respectively, had ≥ 1 diabetes-related ED visit (P ≤ 0.005 for all). Mean baseline A1c was similar in persistent and nonpersistent cohorts (9.7% vs. 9.6%, respectively; P = 0.63). Persistence with MDI was associated with greater mean reduction in A1c (-1.3% vs. -0.8%, respectively; P = 0.006) and greater percentages of patients achieving treatment success (55% vs. 39%, respectively, for nonpersistent; P = 0.009). CONCLUSIONS Poor persistence with basal-bolus insulin therapy over 12 months of follow-up was prevalent and was associated with greater medical costs, greater HCRU, and poorer glycemic control than for patients who were persistent.

Abstract
Continuous subcutaneous insulin infusion (CSII) is an effective therapy to control hyperglycemia in both patients with type 1 diabetes and type 2 diabetes. However, there is little data investigating the insulin dose setting during CSII therapy in type 2 diabetes to achieve optimal glycemic control and avoid the risk of hypoglycemia. Thus, this study is aimed to assess the dose characteristics of insulin requirement and explore the related clinical factors in patients with type 2 diabetes who were treated with CSII. A total of 327 patients (195 males) aged 52.9±12.5 years old were included in this study. Patients were treated with CSII to achieve the target fasting capillary blood glucose (4.4-7.0 mmol L-1) and 2-h postprandial capillary blood glucose (4.4-10.0 mmol L-1) by adjusting insulin infusion according to the seven-point capillary blood glucose profiles. Total daily insulin dose (TDD), total daily insulin dose per kilogram (TDD kg-1) and the ratio of total basal insulin dose (TBD) to TDD (%TBa) were calculated after patients achieved the glucose targets for at least 3 days via 1-2 weeks of CSII treatment. And insulin dose, insulin dosing patterns and the relevant clinical factors were analyzed. The mean ratio of basal/bolus insulin distribution of all patients was 40%:60%. Patients with central obesity needed more TDD (51.3±17.1 U versus 43.5±14.0 U, P<0.05) and TDD kg-1 (0.8±0.3 U kg-1 versus 0.7±0.2 U kg-1, P<0.05) than those without central obesity. Pearson's correlation analysis demonstrated that TDD was positively correlated with body mass index (BMI), waist circumference (WC), baseline fasting plasma glucose (FPG), fasting C-peptide level, 2 h-postprandial C-peptide level and time to achieve glycemic target (all P<0.05); TDD kg-1 was positively correlated with waist-to-hip ratio (WHR), baseline FPG, glycosylated hemoglobin A1c (HbA1c), fasting C-peptide level and time to achieve glycemic target, and negatively correlated with BMI (all P<0.05). Multiple linear regression analyses revealed that BMI (β=1.796, P<0.01), WC (β=0.709, P<0.01), baseline FPG (β=1.459, P<0.01) and HbA1c (β=0.930, P=0.021) were independently related to TDD. Gender (β=-0.107, P=0.003), WC (β=0.005, P=0.029), baseline FPG (β=0.025, P<0.01) and HbA1c (β=0.016, P=0.007) were independently associated with TDD kg-1. Gender (β=-0.015, P=0.048) and disease duration (β=0.134, P=0.029) were independently associated with %TBa. %TBa is around 40% in Chinese patients with type 2 diabetes treated with CSII when glycemic control is achieved. In addition to body weight or BMI, WC and glucose levels before CSII should be considered to set TDD. Patients with central obesity or poor glycemic control might need more TDD. Higher %TBa should be considered in female patients or patients with longer disease duration.

Cost-Effectiveness of Continuous Subcutaneous Insulin Infusion Versus Multiple Daily Injections in Patients with Poorly Controlled Type 2 Diabetes in Finland. Diabetes Ther 2019; 10:563-574.

Abstract
INTRODUCTION Although primarily utilized in type 1 diabetes, continuous subcutaneous insulin infusion (CSII) represents a useful treatment alternative for patients with type 2 diabetes who are unable to achieve good glycemic control despite optimization of multiple daily injections (MDI). The aim of the analysis reported here was to investigate the long-term cost-effectiveness of CSII versus MDI in type 2 diabetes patients with poor glycemic control in Finland. METHODS The IQVIA CORE Diabetes Model was used to make long-term projections of the clinical and economic outcomes associated with CSII use in type 2 diabetes, based on clinical input data from the OpT2mise trial, which showed that CSII was associated with a 1.1% decrease in glycated hemoglobin (HbA1c) in patients with poor glycemic control at baseline. The analysis was performed from a societal perspective and the time horizon was that of patient lifetimes. Future costs and clinical outcomes were discounted at 3% per annum. RESULTS Continuous subcutaneous insulin infusion was associated with a gain in quality-adjusted life expectancy of 0.32 quality-adjusted life-years (QALYs) compared with MDI (8.15 vs. 7.83 QALYs, respectively), as well as higher mean lifetime costs, resulting in an incremental cost-effectiveness ratio of Euro (EUR) 47,834 per QALY gained for CSII versus MDI. The higher treatment costs in the CSII group were partly mitigated by a 15% reduction in diabetes-related complication costs. Sensitivity analyses demonstrated that CSII was most cost-effective in patients with the highest baseline HbA1c values. CONCLUSION In Finland, CSII is likely to represent a cost-effective treatment alternative for patients with type 2 diabetes with poor glycemic control despite optimization of MDI. In such patients, CSII is associated with improved clinical outcomes relative to MDI, with the higher acquisition costs partly offset by a lower lifetime incidence and cost of diabetes-related complications.

Abstract
PURPOSE Therapy for patients with type 2 diabetes (T2DM) not achieving hemoglobin (Hb) A1c targets may progress from an oral antidiabetic drug (OAD) to added basal insulin and then to multiple daily injections of basal-bolus insulin (MDI); however, the relative clinical and economic burden experienced by patients prescribed MDI for T2DM is not well quantified. The intent of this work was to describe direct medical costs, health care resource utilization, and glycemic control in patients with T2DM exposed to MDI in a clinical practice setting. METHODS This retrospective cohort study used administrative claims data (2012-2015, United States) from patients aged 18 to 64 years with T2DM prescribed OAD, basal insulin, or MDI therapy. Eligible patients had continuous enrollment from ≥6 months before to 12 months after the date of the index prescription drug claim. Patients eligible for inclusion in the MDI cohort had ≥2 pharmacy claims each for basal and bolus insulin from the index date through the postindex period. Glycemic control, defined as an HbA1c value of <7% during the last 9 postindex months, was assessed in a subset of patients with HbA1c data available from that period. Descriptive analyses were performed. FINDINGS We identified 225,135 patients with T2DM and claims for an OAD (n = 188,230), basal insulin (n = 23,724), or MDI (n = 13,181). The mean age was 51 or 52 years in each cohort; 54% to 59% of patients in each cohort were men. The mean Charlson comorbidity index scores were 0.8, 1.4, and 1.8, respectively; the percentages of patients with obesity and diabetes-related complications were greatest in the MDI cohort compared with OAD and basal insulin cohorts. The mean direct medical costs (all-cause; year-2015 US $) were $9368 in the OAD cohort, $14,420 in the basal insulin cohort, and $25,624 in the MDI cohort; diabetes-related costs were $3396, $7285, and $13,538. In the OAD, basal insulin, and MDI cohorts, 7%, 9%, and 14% of patients had ≥1 hospitalization, and 17%, 20%, and 24% had ≥1 emergency department visit, while 5%, 7%, and 11% had ≥1 diabetes-related hospitalization, and 8%, 11%, and 15% had ≥1 diabetes-related emergency department visit. Glycemic control was found in 64%, 22%, and 15% of patients in the OAD, basal insulin, and MDI cohorts. IMPLICATIONS These findings suggest that patients prescribed MDI therapy for T2DM have greater disease burden, experience greater medical costs and health care resource utilization, and exhibit poorer glycemic control than do patients treated with OAD or basal insulin therapy.

Abstract
The American Diabetes Association and the European Association for the Study of Diabetes convened a panel to update the prior position statements, published in 2012 and 2015, on the management of type 2 diabetes in adults. A systematic evaluation of the literature since 2014 informed new recommendations. These include additional focus on lifestyle management and diabetes self-management education and support. For those with obesity, efforts targeting weight loss, including lifestyle, medication and surgical interventions, are recommended. With regards to medication management, for patients with clinical cardiovascular disease, a sodium-glucose cotransporter-2 (SGLT2) inhibitor or a glucagon-like peptide-1 (GLP-1) receptor agonist with proven cardiovascular benefit is recommended. For patients with chronic kidney disease or clinical heart failure and atherosclerotic cardiovascular disease, an SGLT2 inhibitor with proven benefit is recommended. GLP-1 receptor agonists are generally recommended as the first injectable medication.

Abstract
AIMS The relative contribution of basal hyperglycaemia (BHG) and postprandial hyperglycaemia (PPHG) in type 2 diabetes patients treated with multiple daily injections (MDI) of insulin is poorly documented. In this study, the BHG and PPHG of patients from the OPT2mise study who were initially treated with MDI were assessed before randomization and again after 6 months of continuous subcutaneous insulin infusion (CSII). MATERIALS AND METHODS Blinded continuous glucose monitoring (CGM) data were collected in 259 MDI patients after completion of an 8-week run-in period. The hyperglycaemic area under the curve (AUC) during the 24-hour basal period (AUC-B) and the postprandial period (AUC-P) were compared with analysis of variance based on contribution to total hyperglycaemia in HbA1c groups (Group 1, <8%; Group 2, 8%-8.4%; Group 3, 8.5%-8.9%; Group 4, 9%-9.4%; Group 5, ≥9.5%). Changes in AUC-B and AUC-P were assessed after 6 months of pump therapy in 131 randomized participants with available CGM recordings. RESULTS In patients undergoing MDI therapy, AUC-B was 21.6% to 54.8% lower in Group 4 to 1 (P = .0138 and P = .0002, respectively) in comparison to Group 5. In contrast, AUC-P did not differ among HbA1c groups (P = .1009). HbA1c correlated with AUC-B, but not with AUC-P. After switching to CSII, AUC-B and AUC-P decreased by 21% and 17%, respectively. When comparing responders with non-responders to CSII therapy, no between-group differences were observed in AUC-B and AUC-P. CONCLUSIONS Basal hyperglycaemia is the major determinant of overall exposure to hyperglycaemia in type 2 diabetes with MDI failure.

Abstract
AIM To evaluate the PAQ® (CeQur SA, Horw, Switzerland), a wearable 3-day insulin delivery device that provides set basal rates and bolus insulin on demand, in people with Type 2 diabetes. METHOD Adults with Type 2 diabetes with HbA1c concentrations ≥53 and ≤97 mmol/mol (7.0 and 11.0%) while treated with ≥2 insulin injections/day were enrolled in two single-arm studies comprising three periods: a baseline (insulin injections), a transition and a PAQ treatment period (12 weeks). Endpoints included HbA1c , seven-point self-monitored blood glucose, total daily dose of insulin and body weight. Safety was assessed according to examination, hypoglycaemic episodes and adverse device effects. RESULTS A total of 28 adults were enrolled (age 63 ± 7 years, 86% men, BMI 32.3 ± 4.3kg/m2 , Type 2 diabetes duration 17 ± 8 years, HbA1c 70 ± 12 mmol/mol (8.6 ± 1.1%), total daily insulin dose 58.7 ± 20.7 U), of whom 24 completed the studies. When transitioned to PAQ, 75% of participants continued on the first basal rate selected. After 12 weeks of PAQ wear, significant improvements from baseline were seen [HbA1c -16 ± 9 mmol/mol (95% CI -20, -12) or -1.5 ± 0.9% (95% CI -1.8, -1.1) P<0.0001], and at all seven self-monitored blood glucose readings time points (P ≤0.03). Total daily insulin dose increased by 12.1 ± 19.5 U (95% CI 3.9, 20.4; P=0.0058), the number of meal time boluses increased by 0.9 ± 1.5/day (95% CI 0.3, 1.5; P=0.0081) and body weight remained stable. Six participants had mild to moderate catheter site reactions and one mild skin irritation occurred. No participant experienced severe hypoglycaemia. CONCLUSIONS Adults with Type 2 diabetes were safely transitioned from insulin injections to the PAQ and had significantly improved glycaemic control and treatment satisfaction with insulin therapy.

Abstract
BACKGROUND The ongoing improvement of continuous glucose monitoring (CGM) sensors and of insulin pumps are paving the way for a fast implementation of artificial pancreas (AP) for type 1 diabetes (T1D) patients. The case for type 2 diabetes (T2D) patients is less obvious since usually some residual beta cell function allows for simpler therapy approaches, and even multiple daily injections (MDI) therapy is not very widespread. However, the number of insulin dependent T2D patients is vastly increasing and therefore a need for understanding chances and challenges of an automated insulin therapy arises. Based on this background, this article analyzes conditions under which the use of more advanced therapeutic approaches, particularly AP, could bring a substantial improvement and should be considered as a viable therapy option. METHOD Data of 14 insulin-treated T2D patients on MDI wearing a CGM device and deviation analysis methods were used to estimate the expected improvements in the clinical outcome by using self-monitoring of blood glucose (SMBG) with advanced carbohydrate counting, a full AP or intermediate approaches, either CGM measurements with MDI therapy or SMBG with insulin pump. HbA1C and time in range (70-140 mg/dl, 70-180 mg/dl, respectively) were used as a performance measure. Outcome measures beyond glycemic control (eg, compliance, patient acceptance) have not been analyzed in this study. RESULTS AP has the potential to improve the condition of many poorly controlled insulin-treated T2D patients. However, as the interpatient variability is much higher than in T1D, a prescreening is recommended to select suitable patients. CONCLUSIONS Clinical criteria need to be developed for inclusion/exclusion of T2D patients for AP related therapies.

Cost-effectiveness of Simple Insulin Infusion Devices Compared to Multiple Daily Injections in Uncontrolled Type 2 Diabetics in the United States Based on a Simulation Model.

Abstract
BACKGROUND As type 2 diabetes (T2D) progresses, administering basal and bolus insulin through multiple daily injections (MDI) is often required to achieve target control, although many people fail to achieve target levels. Continuous subcutaneous insulin infusion (CSII) treatment with traditional pumps has proven effective in this population, but use remains limited in T2D due to CSII cost and complexity. A new class of simple insulin infusion devices have been developed which are simpler to use and less expensive. This paper assesses at what price one such simple insulin infusion device, PAQ® (Cequr SA, Switzerland), may be cost-effective compared to MDI in people with T2D not in glycemic control in the United States. METHODS Published equations were used in a simulation model to project long-term cost-effectiveness over 40 years, combined with data from the recent OpT2mise study, assuming similar efficacy of CSII and simple insulin infusion. Cost-effectiveness was pre-defined in relation to per capita gross domestic product (GDP), where incremental cost-effectiveness ratios below 1X the per capita GDP per quality-adjusted life year (QALY) gained were defined as "highly cost-effective" and below 3X GDP per capita as "cost-effective." RESULTS Simple insulin infusion resulted in 0.17 QALYs gained per patient compared to MDI, along with lifetime cost-savings of USD 66 883 per person due to reduced insulin use and less complications. Analyses on price sensitivity of simple insulin infusion indicated that a device such as the PAQ is cost-effective compared with MDI up to price points of around USD 17 per day. CONCLUSIONS For people with T2D not in glycemic control on MDI, simple insulin infusion devices such as PAQ have the potential to be highly cost-effective in the United States.

Abstract
BACKGROUND Type 2 diabetes mellitus (T2D) is a growing global epidemic. Due to the progressive nature of the disease, many people with T2D require insulin at some point, most commonly a long-acting (basal) insulin to assist with 24-h control of glucose levels. OBJECTIVE This opinion paper provides an overview of considerations for primary care providers (PCPs) in intensifying the treatment regimen when basal insulin therapy is inadequate. RESULTS Control of mealtime hyperglycemia, in addition to fasting hyperglycemia, has been shown to be crucial in reaching A1c goals of <7.0%. However, initiating and optimizing mealtime insulin therapy can be challenging for both people with T2D and PCPs, due to a perceived lack of efficacy and burden of insulin treatment, causing "psychological insulin resistance" in people with T2D and clinical inertia among PCPs. Successful implementation of mealtime insulin therapy requires not only choosing appropriate treatment strategies, but also addressing patient-related behavioral and emotional barriers. Simplified treatment algorithms, combined with the use of advanced technology (devices such as insulin pens, pumps, and patches), and collaborative decision-making can help decrease barriers to effective mealtime insulin therapy. CONCLUSIONS It is possible to implement an effective basal-bolus insulin regimen in people with T2D in a way that improves glucose control while minimizing negative effects on quality-of-life, treatment satisfaction, and psychological well-being.

Abstract
BACKGROUND This prospective single-center study recruited insulin-resistant continuous subcutaneous insulin infusion (CSII) therapy-naive patients with type 2 diabetes (T2D) using insulin analog-based multiple daily injections (MDI) therapy and metformin. METHODS A total of 23 individuals with T2D (70% male), aged a mean ± standard deviation 57.2 ± 8.03 years, with body mass index of 36.2 ± 7.02 kg/m2, diabetes duration of 13.3 ± 4.64 years, and HbA1c of 10.0% ± 1.05% were randomly assigned to a CSII arm or an MDI continuation arm to explore glucose control, weight loss, total daily insulin dose (TDD), and insulin resistance. Insulin dosing was optimized over a 2-month run-in period. RESULTS At 6 months, patients assigned to the CSII arm achieved a significant mean HbA1c reduction of -0.9% (95% confidence interval [CI] = -1.6, -0.1), while reducing their TDD by -29.8 ± 28.41 U/day (33% of baseline [92.1 ± 20.35 U/day]) and achieving body mass (BM) reduction of -0.8 ± 5.61 kg (0.98% of baseline [104.8 ± 16.15 kg]). MDI patients demonstrated a nonsignificant HbA1c reduction of -0.3% (95% CI = -0.8, 0.1) with a TDD reduction of 5% from baseline (99.0 ± 25.25 U/day to 94.3 ± 21.25 U/day), and a BM reduction of -1.0 ± 2.03 kg (0.99% of baseline [108.9 ± 20.55 kg]). After 6 months, the MDI arm crossed over to CSII therapy. At 12 months, patients continuing CSII demonstrated an additional mean 0.7% HbA1c reduction with 54.6% achieving HbA1c<8%. The final TDD reduction was -9.7 U/day in comparison to baseline; BM increased by 1.1 ± 6.5 kg from baseline. The MDI patients that crossed to CSII showed an HbA1c reduction of -0.5% ± 1.04%, HbA1c response rate of 27.3%, a TDD reduction of -17.4 ± 21.06 U/day, and a BM reduction of -0.3 ± 3.39 kg. Diabetic ketoacidosis or severe hypoglycemia did not occur in either arm. CONCLUSION CSII therapy safely and significantly improved metabolic control with less insulin usage, with no sustainable reduction of BM, blood pressure, and lipid profile, in insulin-resistant T2D patients. Treatment adherence and satisfaction in these patients were excellent.

Abstract
It is unknown whether YOD (young onset diabetes) and LOD (late onset diabetes) require similar insulin doses for intensive insulin therapy with a metformin add-on to achieve glycemic control. We analyzed data from our two previously performed randomized, controlled open-label trials. Patients were randomized to receive either continuous subcutaneous insulin infusion (CSII) therapy or CSII combined with metformin therapy for 4 weeks. The studies concentrated on the differences in the insulin doses used for the two groups. We included 36 YOD (age < 40 yrs) and 152 LOD (age > 40 yrs) patients. YOD patients who received metformin combined with CSII therapy required significantly lower insulin doses to maintain euglycemic control compared to patients with LOD. A multivariate analysis, controlled for gender and the fasting blood concentration, was performed to determine the significance of the differences between groups, particularly with respect to the total and basal insulin doses. There was a trend toward improvement in β-cell function and insulin resistance in terms of ΔHOMA-B and ΔHOMA-IR in patients with YOD compared to those with LOD. Newly diagnosed T2D patients with YOD required significantly lower insulin doses, particularly basal insulin doses, to maintain glycemic control compared to the LOD patients.

Abstract
Worldwide, many people with type 2 diabetes are not at recommended glycemic targets and remain at increased risk of microvascular and macrovascular complications. Reaching recommended glycemic targets requires normalizing both fasting and postprandial glucose (PPG). For some patients, this will require addition of a prandial insulin delivered by injection to control PPG excursions. Evidence from epidemiological studies suggests an association between postprandial hyperglycemia and cardiovascular disease, and thus, expert guidelines recommend that treatment for elevated PPG not be delayed. Indeed, studies have demonstrated that PPG makes the greatest contribution to HbA1c in patients who are approaching, but have not yet reached HbA1c <7.0%. Appropriately timed exposure of the liver to insulin is critical in suppressing hepatic glucose output (and therefore PPG levels) after a meal. Rapid-acting insulin analogs, with their faster onset and shorter duration of action, offer advantages over regular human insulin. Unfortunately, even with improved pharmacokinetic/pharmacodynamic characteristics, rapid-acting insulin analogs are still unable to fully reproduce the rapid release of insulin into the portal circulation and suppression of hepatic glucose output that occurs in the individual without diabetes after starting a meal. The next generation of rapid-acting insulin analogs will have an even more favorable pharmacokinetic profile that should allow patients to further improve glycemic control. Continuous subcutaneous insulin infusion (CSII) represents another option for intensifying therapy and improving postprandial control in some patients, and studies have shown that the benefits are sustainable long-term. However, it is currently unclear which patients stand to benefit the most from the extra expense and complexity of a CSII regimen, and further studies are needed.

Abstract
This analysis investigated factors associated with the decrease in HbA1c in patients receiving continuous subcutaneous insulin infusion (CSII) in the OpT2mise randomized trial. In this study, patients with type 2 diabetes and HbA1c >8% following multiple daily injections (MDI) optimization were randomized to receive CSII (n = 168) or MDI (n = 163) for 6 months. Patient-related and treatment-related factors associated with decreased HbA1c in the CSII arm were identified by univariate and multivariate analyses. CSII produced a significantly greater reduction in HbA1c than MDI, and the treatment difference increased with baseline HbA1c. In the CSII arm, the only factors significantly associated with decreased HbA1c were higher baseline HbA1c (P < .001), geographical region (P < .001), higher educational level (P = .012), higher total cholesterol level (P = .002), lower variability of baseline glucose values on continuous glucose monitoring (P < .001) and the decrease in average fasting self-monitored blood glucose at 6 months (P < .001). These findings suggest that CSII offers an option to improve glycemic control in a broad range of patients with type 2 diabetes in whom control cannot be achieved with MDI.

Abstract
Obesity has been estimated to decrease life expectancy by as little as 0.8 to as much as 7 years being the second leading cause of preventable death in the United States after smoking. Along with the increase in the prevalence of obesity, there has been a dramatic rise of the prevalence of prediabetes and type 2 diabetes among adolescents. Despite that, very little is known about the pathogenesis of these conditions in pediatrics and about how we could detect prediabetes in an early stage in order to prevent full blown diabetes. In this review we summarize the current knowledge on the pathophysiology of prediabetes and type 2 diabetes in adolescents and describe how biomarkers of beta-cell function might help identifying those individuals who are prone to progress from normal glucose tolerance towards prediabetes and overt type 2 diabetes. To better understand and fight this disease, we will need to explore and develop novel therapeutic strategies and individuate more sensitive and specific biomarkers that can allow an earlier detection of the disease.

Abstract
BACKGROUND Continuous subcutaneous insulin infusion (CSII) is used less for type 2 than for type 1 diabetes because of inconsistencies in evidence of effectiveness. We reviewed published guidelines on intensive insulin therapy in type 2 diabetes to assess whether updating of guidance is needed with respect to evidence used and recommendations for CSII in diabetes management. METHODS A literature review was performed to identify published national and international guidelines on type 2 diabetes management. Searches were performed using PubMed, Cochrane Library, and Embase databases, and websites of national health care agencies, reimbursement agencies, and professional associations. Searches were limited to articles published in English between 2004 and 2014 and 1666 unique hits were identified, of which 22 were reviewed following screening. RESULTS Only 6 of the 22 guidelines identified from North and South America, Western Europe, Greece, and Israel provided specific recommendations on intensive insulin therapy and the role of CSII, and only 1 provided information on the grade of evidence supporting recommendations. Quality appraisal based on the AGREE II tool suggested that published guidelines may have limitations in terms of search methodology and evidence grading, and findings were of mixed rigor and clarity. Only 3 guidelines described the population for whom CSII may be appropriate. CONCLUSIONS Guidelines need to improve the evidence base, rigor, clarity, and grading of evidence associated with recommendations on intensive insulin therapy in type 2 diabetes. Future updates may benefit from considering recent evidence on the efficacy of CSII in poorly controlled patients on MDI.

Abstract
AIM Diabetes is an emerging health problem, both in developing and developed countries and has an enormous economic and social impact. The objective of our study was to find the impact of insulin pump on the quality of life of patients with type 2 diabetes (T2D) and compare it to the quality of life of patients with T2D using an insulin pen. SUBJECTS AND METHODS This is a case-control study which was conducted among patients with T2D presenting between November 2014 and November 2015. A total of 83 patients with T2D, using insulin pump were enrolled in the study as cases and 322 patients with T2D not using insulin pump but using insulin pens were enrolled as controls. Short form-36 quality of life questionnaire was used for data collection. RESULTS Mean age of patients using insulin pump was 52.49 ± 9.28 while the mean age of patients not using insulin pump was 54.72 ± 16.87. Mean score of all domains in the questionnaire was found to be higher in patients using insulin pump as compared to patients not using insulin pumps (P < 0.05). In 81.1% of the patients, the insulin pump decreased the frequency of hypoglycemic episodes. CONCLUSION Insulin pump has significantly improved the quality of life of patients in terms of better self-esteem, decreased stress, and better mood. It has resulted in improved physical health, meal time flexibility, and ease of travel. It allows patient to have more active participation in social and recreational activities improving their personal and family life.
