RESUMO
AIMS: To compare the efficacy and safety of tirzepatide 5, 10 and 15 mg with subcutaneous semaglutide 0.5 mg as second-line treatment for adults with type 2 diabetes mellitus, after metformin monotherapy, using adjusted indirect treatment comparisons (aITCs). METHODS: The aITCs were performed using the Bucher method to compare the relative efficacy and safety of tirzepatide 5, 10 and 15 mg versus semaglutide 0.5 mg via a common comparator (subcutaneous semaglutide 1.0 mg) based on trial results from SURPASS-2 (NCT03987919) and SUSTAIN7 (NCT02648204). RESULTS: All tirzepatide doses showed statistically significantly greater reductions in glycated haemoglobin, body weight and body mass index from baseline to week 40, with a comparable adverse event (AE) profile and no statistically significant differences in the odds of gastrointestinal AEs versus semaglutide 0.5 mg. Furthermore, all tirzepatide doses showed greater odds of patients achieving HbA1c targets of ≤ 6.5 % (≤48 mmol/mol) and < 7.0 % (<53 mmol/mol) and weight loss targets of ≥ 5 % and ≥ 10 %, versus semaglutide 0.5 mg. CONCLUSIONS: In these aITCs, glycated haemoglobin and weight reductions were significantly greater for all tirzepatide doses versus semaglutide 0.5 mg with a comparable AE profile. These findings provide comparative effectiveness insights in the absence of a head-to-head clinical trial.

AIMS: Continuous glucose monitoring (CGM) metrics can assist diabetes management. Consensus statements recommend > 70 % time in range (TIR) and ≤ 36 % glucose coefficient of variation (CV). However, how these targets perform in clinical practice is unknown. This retrospective, longitudinal cohort study analyzed relationships between TIR, CV, glycated hemoglobin (HbA1c), and hypoglycemia in a real-world setting. METHODS: Data of 542 adults with type 1 diabetes who used CGM (January 2014-July 2020) were analyzed. Associations between TIR and HbA1c at the same and subsequent visits, incidence rate ratios (IRRs) for hypoglycemia at different CVs, and number of hypoglycemic events at cross-sections of HbA1c and CV were estimated by regression. RESULTS: TIR was inversely related to HbA1c; for every 10 % increase in TIR, HbA1c was significantly reduced by 0.34 % (4 mmol/mol) and 0.20 % (2 mmol/mol) at the same and subsequent visits, respectively. Level 2 hypoglycemia was significantly reduced at CV < 30 %, 30-33 %, 33.1-36 %, and 36.1-40 %: adjusted IRRs vs CV ≥ 40.1 % of 0.14, 0.28, 0.32, and 0.50, respectively. Hypoglycemic events were reduced at lower CV across HbA1c levels and at higher HbA1c across CV levels. CONCLUSION: This study quantifies HbA1c improvements with increased TIR and hypoglycemia reductions with improved CV in clinical practice.

OBJECTIVE: To develop a machine learning-based predictive algorithm to identify patients with type 2 diabetes mellitus (T2DM) who are candidates for initiation of U-500R insulin (U-500R). METHODS: A retrospective cohort of patients with T2DM was used from a large US administrative claims and electronic health records (EHR) database affiliated with Optum. Predictor variables derived from the data were used to identify appropriate supervised machine learning models including least absolute shrinkage and selection operator (LASSO) and extreme gradient boosted (XGBoost) methods. Predictive performance was assessed using precision-recall (PR) and receiver operating characteristic (ROC) area under the curve (AUC). The clinical interpretation of the final model was supported by fitting the final set of variables from the LASSO and XGBoost models to a traditional logistic regression model. Model choice was determined by comparing Akaike Information Criterion (AIC), residual deviances, and scaled Brier scores. RESULTS: Among 81,242 patients who met the study eligibility criteria, 577 initiated U-500R and were assigned to the positive class. Predictors of U-500R initiation included overweight/obesity, neuropathy, HbA1c ≥9% and 8%-9%, BUN 23.8 to <112 mg/dl, ALT 35.9-2056.2 U/L, no radiological chest exams, no GFR labs, and gait/mobility abnormalities. The best performing model was the LASSO model with an ROC AUC of 0.776 on the hold-out test set. CONCLUSION: This study successfully developed and validated a machine learning-based algorithm to identify U-500R candidates among patients with T2DM. This may help health care providers and decision-makers to understand important characteristics of patients who could use U-500R therapies which in turn could support policies and guidelines for optimal patient management.

OBJECTIVE: Insulin pump use is increasing among people with type 2 diabetes (T2D), albeit at a slower rate compared to people with type 1 diabetes (T1D). Factors associated with insulin pump initiation among people with T2D in the real-world are understudied. METHODS: This retrospective, nested case-control study aimed to identify predictors of insulin pump initiation among people with T2D in the United States (US). Adults with T2D who were new to bolus insulin use were identified from the IBM MarketScan Commercial database (2015-2020). Candidate variables of pump initiation were entered into conditional logistic regression (CLR) and penalized CLR models. RESULTS: Of the 32,104 eligible adults with T2D, 726 insulin pump initiators were identified and matched to 2,904 non-pump initiators using incidence density sampling. Consistent predictors of insulin pump initiation across the base case, sensitivity, and post hoc analyses included continuous glucose monitor (CGM) use, visiting an endocrinologist, acute metabolic complications, higher count of HbA1c tests, lower age, and fewer diabetes-related medication classes. CONCLUSIONS: Many of these predictors could represent a clinical indication for treatment intensification, greater patient engagement in diabetes management, or proactive management by healthcare providers. Improved understanding of predictors for pump initiation may lead to more targeted efforts to improve access and acceptance of insulin pumps among persons with T2D.

AIMS: To identify patient clusters with poor glucose control among type 2 diabetes mellitus (T2DM) patients with obesity who are receiving basal-bolus insulin and to identify the potential therapeutic inertia factors associated with poor control. METHODS: Glycated haemoglobin (HbA1c) trajectories across a 3-year period were structured at 6-month intervals for a retrospective cohort of T2DM patients with obesity on basal-bolus insulin from the Veterans' Health Administration database. Based on each patient's longitudinal HbA1c features, an unsupervised clustering procedure was used to determine the numbers of clusters and associated trajectory patterns. Multinomial logistic regression was used to examine the association between HbA1c trajectory clusters and patient characteristics/treatment patterns. RESULTS: A total of 51 273 patients were included, of whom 11.2% were in a subgroup with persistent missingness of HbA1c values. For those with sufficient HbA1c observations, cluster analysis indicated six distinct HbA1c trajectories: stable low (35.8%); stable high (20.8%); descending low (10.5%); ascending low (10.2%); descending high (5.7%); and ascending high (5.7%). Being of Black ethnicity, not initiating noninsulin antihyperglycaemic agents (sodium-glucose cotransporter-2 inhibitors, glucagon-like peptide-1 receptor agonists or thiazolidinediones) or concentrated insulin, low adherence (measured by proportion of days covered), and reduced insulin prescription refills were factors associated with poorer HbA1c clusters; similar factors were associated with persistent HbA1c missingness. CONCLUSION: The present study found the potential for therapeutic inertia among a significant proportion of T2DM patients with obesity on basal-bolus insulin. Subgrouping T2DM patients based on HbA1c missingness and HbA1c trajectories can inform disease management strategies.

With the changes in people's dietary life, the incidence and mortality of colon cancer have risen sharply. Invasive metastasis of colon cancer is the main reason affecting the prognosis. Therefore, it is very important to study the molecular mechanism of SDF-1/CXCR4 and integrin αvß6 in liver metastasis of colon cancer. Floating cells were used to detect the appearance of ß6, and the relationship between SDF-1/CXCR4 and the molecular mechanism of colon cancer redirection was analyzed. Use immunohistochemistry to detect the appearance of SDF-1/CXCR4 and αvß6 protein, and combine the data with clinical-pathological data for statistical analysis. Experimental data showed that the positive expression rates of αvß6 protein in well-differentiated and poorly differentiated colon cancer tissues were 21.4% and 30.6%, respectively, and the difference was statistically significant (P<0.01). The results show that the appearance of SDF-1/CXCR4 in colon cancer cells (CCC) has nothing to do with the type of cancer cells, and increases with the decrease of cell differentiation. This has a great relationship with the classification of the clinical TNM disease stage. The later the disease stage, the higher the expression level. The αvß6 has a strong correlation with the invasion and metastasis of colon cancer and can be used as a criterion for judging liver metastasis and prognosis.

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 appropriate switching to U-500R by payers. The study compared the treatment patterns and outcomes before and after U-500R initiation among patients who were identified with ≤ 200 units/day U-100 insulin fill in order to understand the appropriateness of switching. METHODS: Patients with type 2 diabetes who initiated U-500R (index date = first fill) with ≤ 200 units/day pre-index dTDD and > 200 units/day post-index dTDD were identified in a Veterans Health Administration dataset between 1 January 2014 and 30 June 2017. Descriptive analysis was conducted on treatment patterns (dTDD, insulin dosage [units/kg], adherence, number of prescription fills) and clinical outcomes (HbA1c, symptomatic hypoglycemic events). Associations between U-500R exposure and outcomes were evaluated using mixed-effects models. Subgroups of U-500R syringe and KwikPen users were analyzed separately. RESULTS: Among 1191 U-500R initiators identified in the study the mean dTDD increased from the pre- to post-index periods (147.2 vs 346.3; p < 0.0001). The mean HbA1c decreased from pre- to post-initiation (9.6% vs 8.6%; p < 0.0001), and symptomatic hypoglycemia events per patient per year increased (2.0 vs 3.3, p < 0.0001). Mixed-effects models confirmed the significance of the changes (p < 0.0001). Device subgroups followed similar trends. CONCLUSIONS: U-500R initiation was associated with large dTDD increases, improved glycemic control, and modest increases in hypoglycemia events, suggesting U-500R initiation may have corrected previous treatment compliance issues. Imposing dTDDs > 200 units before switching to U-500R criterion could hurt the opportunities for patients who need a simplified regimen for better outcomes.
RESUMO
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: The IBM® MarketScan® Commercial and Medicare databases were used to identify trends in insulin use over 10 years. The study included people with T1D or T2D who filled a prescription for insulin in any calendar year from 2009 to 2018. The analyses examined insulin regimen and delivery and the use of glucose monitoring systems. Generalized estimating equations were used to test whether trends were statistically significant. RESULTS: Individuals with T1D were most commonly prescribed a basal and bolus insulin regimen or short/rapid insulin only, while for people with T2D the use of basal-only insulin increased significantly over the study period. In both groups there was a significant decline in the use of premix insulin from 2009 to 2018. Insulin pump use increased for individuals with T1D, while disposable pen use increased for people in both cohorts. In both cohorts, there was a statistically significant increase in the use of continuous glucose monitoring, although this increase was more pronounced and occurred earlier among individuals with T1D. CONCLUSIONS: Results indicate significant changes in insulin regimens and delivery and glucose monitoring from 2009 to 2018. These findings suggest that insulin prescribing continues to change in response to the development of new therapeutics, advances in insulin delivery technology, and glucose monitoring systems.

AIM: To identify which individual-, physician-, and the healthcare system-related factors can predict individualized hemoglobin A1c (HbA1c) targets and the likelihood of reaching those targets after initial insulin therapy over a two-year follow-up period. METHODS: Real-world data, including baseline characteristics of people with type 2 diabetes mellitus (T2DM), psychosocial data, and diabetes medication use, collected from the Multinational Observational Study Assessing Insulin Use (MOSA1c) study in 18 countries were analyzed. RESULTS: Overall, 225 of 1194 people with T2DM (18.8%) who received initial insulin therapy for ≥3 months reached HbA1c targets at two-year follow-up; most were likely to be White (64.9%) and perceptions of their relationship with physicians were less positive than those who did not reach HbA1c targets. Higher baseline HbA1c (>8%) was the strongest predictor of being assigned an HbA1c target >7% (odds ratio [OR] 6.06, 95% confidence interval [CI] 3.97, 9.26). A smaller difference between baseline and target HbA1c levels was the strongest predictor of reaching an HbA1c target at two-year follow-up (large vs small difference, OR 0.28, 95% CI 0.17, 0.47). CONCLUSIONS: Several factors were significantly associated with establishing individualized HbA1c targets and reaching these targets. A small proportion of people with T2DM on insulin therapy reached their HbA1c target. Personalized management of glycemic targets necessitates the adoption of multi-factorial strategies, as several factors could influence an individual's glycemic outcome. CLINICALTRIALS.

INTRODUCTION: A dedicated Humulin R U-500 (U-500R) prefilled disposable insulin pen (KwikPen) became available in 2016, yet limited evidence exists on treatment patterns and outcomes of U-500R via KwikPen (U500-KP). METHODS: This is a retrospective observational study among adults with ≥2 claims for type 2 diabetes initiating U500-KP (index date: first claim) identified in Veterans Health Administration database. Treatment patterns and outcomes were evaluated in 9-month pre- and post-index periods, including dispensed total daily insulin dosage derived from claims expressed in units (dTDD) and units/kg, HbA1c, symptomatic hypoglycemia, and body weight. Multivariable modeling was used to confirm the associations between U500-KP initiation and outcomes. RESULTS: A total of 647 U500-KP initiators were identified. The mean age was 64 years, and mean Quan-Charlson Comorbidity-index score was 3.8. Before U500-KP initiation, 62% of patients had dTDD ≤ 200 units with mean A1c 9.5%. Mean dTDD increased from 188.2 to 269.9 units after U500-KP initiation with mean A1c decreased by 0.83% (SD = 1.67) and mean weight gain of 1.5 kg (SD = 6.74). Hypoglycemia events increased from 4.3 to 5.3 (p < 0.05) per person per year. CONCLUSIONS: Initiation of U500-KP brought significant improvement in dispensed insulin dose and glycemic control accompanied by moderate increases in hypoglycemia and weight.

OBJECTIVE: 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, although it remains understudied. This retrospective study compared real-world patient characteristics, treatment patterns, and outcomes before and after U-500R initiation. METHODS: Adults with T2D on dispensed doses of >180 units/d U-500R monotherapy (index date=first fill) with ≥9-month continuous enrollment both pre- and post-index date and ≥180 units/d insulin pre-index were identified using Veterans Health Administration data (January 1, 2014-January 30, 2017). Overall group was further stratified into elderly and 201 to 300 units dispensed total daily dose (dTDD) subgroups. Syringe and KwikPen users were separately analyzed as subcohorts. Treatment patterns (dTDD), insulin dosage (units/kg), proportion of days covered (PDC) with insulins, and outcomes (HbA1c and hypoglycemic events) were descriptively evaluated, with regression models used to confirm associations between exposure and outcomes. RESULTS: Among 951 U-500R initiators (overall group), mean dTDD (248.5 vs 392.1), percentage of patients with insulin dosage >2 units/kg (38.6% vs 88.1%), and mean PDC (73% vs 77%) significantly increased from the pre- to post-index periods (all P<.001). Changes in HbA1c (9.3% vs 8.5%; P<.0001) and hypoglycemia events per patient per year (2.1 vs 3.1, P<.0001) were statistically significant and confirmed by regression models (P<.0001). Subgroups (elderly, 492; 201 to 300 units, 148) and device subcohorts (syringe, 714; KwikPen, 244) showed similar trends. CONCLUSION: U-500R initiation was associated with significantly improved treatment compliance patterns and glycemic control, with modest increase in hypoglycemia events.

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 disruptions led to the majority of participants reporting that their sleep was considerably affected by diabetes. Despite the improvement in blood glucose management that diabetes technology devices can provide, people with type 1 diabetes and their caregivers still report sleep disruption and sleep loss resulting from overnight diabetes management.
RESUMO
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 their perspective. METHODS: An observational cross-sectional online survey was administered through T1D Exchange's online patient community, myGlu.org, to understand the use of half-unit insulin pens. RESULTS: The 278 adult participants (156 EVER, 122 NEVER) had a mean age of 41.8 ± 12.7 years, body mass index of 26.0 ± 3.8 kg/m2, glycated hemoglobin of 6.3% ± 1.0%, and 55% were male. EVER users had T1D for a shorter duration than NEVER users (p < .001). EVER users were less likely to use continuous subcutaneous insulin infusion (p < .001) and more likely to start correcting high blood glucose at a lower level (p < .001) and low blood glucose at a higher level (p < .001). The highest ranked benefits of half-unit pen reported by its current users (N = 131) included prevention of hyperglycemia (40.5%), less anxiety or worry (23.7%), and prevention of hypoglycemia (16.8%). CONCLUSIONS: Half-unit insulin pen is perceived as an insulin device that may help people with T1D to avoid hypo- and hyperglycemic events and decrease their level of disease worry and anxiety. This study highlights the need for patients and health care providers to understand the benefits of half-unit pens while considering options for individualized diabetes management.

Background: The EValuating U-500R Infusion Versus Injection in Type 2 Diabetes Mellitus (VIVID) study compared two methods of U-500R insulin delivery, continuous subcutaneous insulin infusion (CSII) and multiple daily injection (MDI), for 26 weeks in people with type 2 diabetes (T2D) requiring high doses of insulin. To assess glycemic variability (GV) and time in range (TIR), a subset of participants performed masked continuous glucose monitoring (CGM). Methods: VIVID participants were adults who had insulin requirements of >200 but ≤600 U/day and A1C 7.5% to 12%. Participants performed masked CGM for seven consecutive days on each of three occasions: before weeks 0 (baseline), 14, and 26. The primary objective was to compare GV between CSII and MDI groups, based on change from baseline of within-day standard deviation (SDw) of CGM glucose. Results: Of 54 participants enrolled, 41 with evaluable data were analyzed (17 and 24 in CSII and MDI groups, respectively). The CSII group had a significantly greater reduction from baseline in mean SDw of glucose (45.0 to 38.2 mg/dL [-8.1 mg/dL]) compared with the MDI group (47.0 to 45.8 [-0.4 mg/dL]; P = 0.047). TIR 70-180 mg/dL glucose increased significantly from baseline in the CSII group only, from 59.8% to 73.1% (change +12.9%, P < 0.05), but was not significantly different between groups. There were no significant between-group differences in the endpoint mean glucose or A1C. Conclusions: In the VIVID CGM substudy of U-500R in people with T2D requiring high doses of insulin, participants using CSII significantly reduced GV compared with MDI. CSII also significantly increased TIR with no difference between groups.

Human regular U-500 insulin (U-500R) provides both basal and prandial coverage to people with diabetes. As part of the 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 for Diabetes (TRIM-D) for Diabetes Device (TRIM-DD) questionnaires were administered at weeks 0, 14 and 26. TRIM scores with effect sizes (ES) for within-group and between-group change were reported. All TRIM-D scores significantly improved from baseline for both groups (P < .001). The Diabetes Management domain had the greatest improvement, 16.3 (ES = 0.85) and 10.6 (ES = 0.51) for CSII and MDI, respectively. At the study end, the CSII group had significantly higher TRIM-D scores than the MDI group (P < .05). Most TRIM-DD scores had small within-group improvements and were not different between groups. People with type 2 diabetes on U-500R by either CSII or MDI reported improvement in PRO, particularly in Diabetes Management, Treatment Burden and Psychological Health domains, with greater improvement in the CSII group. In terms of delivery device and function, the CSII and MDI methods were similarly acceptable.

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

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 METHODS | We selected patients from the Truven Health MarketScan database who initiated U-500R between 2010 and 2013. We collected data for three periods: pre-index (12 months before initiation), post-index (12 months after initiation or until a gap of ≥60 days in U-500R claims), and follow-up (12 months after post-index). Data were analyzed using descriptive statistics and a regression model as appropriate. RESULTS | We identified 1,582 patients who met the selection criteria. The median TDD of U-500R during the post-index period was 333 units/day, with 70.0% of patients using 300-400 units/day. During the post-index period, 74.1% of patients had U-500R claims that did not overlap with prescriptions for other insulins, interpreted as U-500R monotherapy. Among patients with ≥1 U-500R fill in the post-index period (n = 1,208), 54.4% had a medication possession ratio (MPR, a measure of adherence) ≥80%. Although 849 patients had a gap of ≥60 days in U-500R claims in the post-index period, 602 of those resumed U-500R in the follow-up period. Of the 733 patients who had no gap in U-500R claims in the post-index period, 286 had a gap of ≥60 days in claims in year 2, and 447 continued with U-500R treatment beyond 2 years. CONCLUSION | These results demonstrate that U-500R was commonly used as insulin monotherapy, with a median TDD >300 units/day. Compared with published, relevant studies of other insulins, U-500R showed similar or greater adherence and persistence rates. These new data may help guide clinical decision-making when choosing insulin therapy for patients requiring high doses of insulin.
RESUMO
BACKGROUND: Few studies have examined patient characteristics and treatment patterns of high-dose insulin therapy (> 200 units/day) among patients with type 2 diabetes mellitus (T2DM). OBJECTIVE: To understand patient characteristics, dosing, adherence, and persistence related to high-dose insulin therapy. METHODS: This was a retrospective observational study that used administrative claims from a large national health plan. Patients were identified who had been diagnosed with T2DM and who were aged 18-89 years, enrolled in a commercial or Medicare Advantage Prescription Drug plan, newly initiated on a total daily dose (TDD) > 200 units of insulin between January 2011 and August 2015. Patients were required to be enrolled 6 months before and 12 months after the index date. Patients were categorized to Regimen-100 if treated with U-100 insulin only or Regimen-500 if treated with U-500R with or without U-100. Baseline demographic and clinical characteristics were evaluated. An adjustment factor for the days supply was calculated as the ratio of median time between insulin claims, and median pharmacy reported days supply for each insulin prescription. Adjusted days supply, quantity, and concentration were used to calculate TDD for each quarter after the index date. Adherence was measured as the proportion of days covered (PDC) for each regimen. Persistence was measured in 2 ways: the percentage of patients remaining on index medications in each quarter and the proportion of patients who maintained TDD > 200 units during all 4 quarters of the 12-month post-index period. RESULTS: We identified 2,339 patients newly titrated up to TDD > 200 units on either Regimen-100 (2,062, 88.2%) or Regimen-500 (277, 11.8%). Patients on Regimen-500 were slightly younger with higher prevalence of comorbidities. The mean TDD (SD) for Regimen-100 decreased from 228.6 (36.0) units during the first quarter to 194.2 (181.4) units during the last quarter. The mean TDD (SD) for Regimen-500 increased from 294.2 (102.2) units in the first quarter to 304.8 (281.6) units in last quarter. The average adherence to the high-dose insulin regimen was 68.2% (30.7; median 72.6%) for the Regimen-100 cohort and 75.5% (27.0; median 85.2%) for the Regimen-500 cohort. In the Regimen-100 and Regimen-500 cohorts, 45.3% and 55.2% had a PDC ≥ 80%, respectively. Only 23.0% and 51.6% of patients maintained TDD > 200 units for the Regimen-100 and Regimen-500 cohorts, respectively, throughout the 4 quarters after the index date. CONCLUSIONS: We observed that many patients did not maintain high-dose insulin use over time, especially those on standard U-100 insulin only. This dosing pattern appears to reflect the differences in patient characteristics, insulin needs, and adherence/persistence behavior between those on Regimen-100 and those on Regimen-500.

BACKGROUND: In the United States (U.S.), the prevalence of both diagnosed and undiagnosed type 2 diabetes (T2D) is nearly twice as high among Mexican-origin Hispanic/Latino adults compared to non-Hispanic Whites. Rates of diabetes-related complications, e.g., acute stroke and end-stage renal disease, are also higher among Hispanic/Latino adults compared to their non-Hispanic/Latino White counterparts. Beyond genetic and biological factors, it is now recognized that sociocultural influences are also important factors in determining risk for T2D and the associated complications. These influences include ethnicity, acculturation, residence, education, and economic status. The primary objective of this study is to determine the influence of the 5 major determinants of human health (genetics, biology, behavior, psychology, society/environment) on the burden of T2D for Latino families. To achieve this objective, Mil Familias (www.milfamilias.sansum.org/) is establishing an observational cohort of 1000 Latino families, with at least one family member living with T2D. METHODS: Specially trained, bilingual Latino/a community health workers (Especialistas) recruit participant families and conduct research activities. Each individual family member will contribute data annually on over 100 different variables relating to their genetics, biology, psychology, behavior, and society/environment, creating a Latino-focused biobank ("Living Information Bank"). This observational cohort study is cross-sectional and longitudinal. Participants are divided into 4 groups: adults age ≥ 18 years with and without T2D, and children age ≥ 7 and < 18 years with and without T2D. Study activities take place through encounters between families and their Especialista. Encounters include screening/enrollment, informed consent, health promotion assessment, laboratory tests, questionnaires, physical activity monitoring, and reflection. DISCUSSION: By creating and providing the framework for the Cohort Establishment study, we intend to inform new approaches regarding equity and excellence in diabetes research and care. We will examine the complex set of factors that contribute to the burden of diabetes in Latino families and assess if cardio-metabolic disease risks go beyond the traditional biological and genetic factors. Breaking the code on the interplay of cardio-metabolic risk factors may help not only this fast growing segment of the U.S. population, but also other high-risk populations. TRIAL REGISTRATION: Study retrospectively registered at ClinicalTrials.gov (NCT03830840), 2/5/2019 (enrollment began 2/1/2019).
