Abstract
The effectiveness of therapy in patients with diabetes depends on the correct use of the insulin injection technique. However, despite many established recommendations and evidence that an effective insulin injection technique is essential to improve glycaemic control and minimise the risk associated with diabetes, there is still a need to identify impediments to the insulin injection technique among patients and create awareness among patients and healthcare professionals about the importance of the optimisation of insulin injection techniques. This review focuses on the recent advancements in delivery devices, insulin injection technique teaching methods, monitoring, and complication management and highlights regional best practices and recommendations for optimising injection techniques to improve diabetes outcomes.

Abstract
OBJECTIVE To review the current status of practical knowledge related to insulin-associated lipohypertrophy (LH) - an accumulation of fatty subcutaneous nodules commonly caused by repeated injections and/or infusions of insulin into the same site. METHODS Review of published literature with additional contributions from leading multidisciplinary experts with the emphasis on clinical aspects including pathophysiology, clinical and economic consequences, diagnosis, prevention and treatment. RESULTS LH is the most common dermatologic complication of insulin therapy. Risk factors for the development of lipohypertrophy include repeated delivery of large amounts of insulin into the same location over time, repeated injection trauma to the skin and subcutaneous tissue, and multiple injections using the same needle. Subcutaneous insulin injection in skin areas with lipohypertrophy is associated with reduced pain; however, this problem can interfere with insulin absorption, thereby increasing the likelihood of glucose variability, hypo- and hyperglycemia when a site is changed. Modern visualization technology of the subcutaneous space with ultrasound can demonstrate lipohypertrophy early in the course of its development. CONCLUSIONS The physiological and psychological consequences of developing insulin lipohypertrophy can be prevented and treated with education focusing on insulin injection techniques.

Abstract
INTRODUCTION Cutaneous lipohypertrophy (LH) is a thickened, "rubbery" lesion in the subcutaneous tissue following multiple injections performed at the same site, i.e., an incorrect injection technique. It is widespread, averaging 47% of insulin patients worldwide, and has severe direct and indirect consequences. Direct consequences consist mainly of poor metabolic control and frequent hypoglycemic events (HYPOs), and indirect ones of markedly increased healthcare costs related to hospital access due to acute events and long-term disease complications. This observation also holds for Italy, despite the National Health System organization expecting every patient with diabetes to undergo a series of visits by different care team members, each performing a specific treatment/education task. Indeed, the recent literature points to poor awareness of LH relevance and metabolic consequences among doctors from general and diabetic hospital wards, with educational deficiencies on correct injection practice in nurses too. The aim was to establish if, to what extent, and by whom they had received training on correct insulin injection techniques, and how many initially received notions had persisted over time. METHODS We investigated the possible causes of such a failure from the point of view of 1160 insulin-requiring subjects with type 2 diabetes (T2DM), reporting for the first time to specialized diabetic structures through a validated questionnaire and, in the same patients, we searched for LH by inspection/palpation according to international guidelines, further confirmed by ultrasound scans. We then analyzed differences in education and injecting behavior between subjects classified as LH+ or LH- depending on the presence or absence of LH lesions. RESULTS We documented significant educational gaps, with 50% of patients failing to refer to healthcare professionals and relying on their peers with diabetes, thought to be more experienced in 15% of the cases. Seventy-five percent of LH- patients received education from healthcare providers, while 90% of LH+ learned from another patient or could not remember how they knew, and 68% of LH+ versus 52% of LH- (p < 0.01) patients had failed to receive training on injection techniques by healthcare providers. All of this enabled the most disabling features of diabetes from the very beginning of the disease history. CONCLUSIONS This study documents, from the patients' point of view, that educational gaps are significant and that, even in initially trained subjects, education on correct injection techniques has a fleeting effect if not regularly recalled. Therefore, to rehabilitate LH+ patients as soon as possible and prevent LH- patients from inadvertently slipping into the other group, there is an urgent need to educate doctors and nurses repeatedly on the importance of correctly injecting insulin to improve patients' knowledge and skills.

Abstract
INTRODUCTION Insulin, which is used in the treatment of diabetes mellitus (DM), may lead to the development of lipohypertrophy (LH) which can negatively affect the management of diabetes mellitus. Two common methods to detect LH are palpation and superficial subcutaneous ultrasonography (SSU). We investigated the frequency of non-palpable LH using SSU, as well as examining risk factors. METHOD We included in our study patients who had been receiving insulin injections at least twice a day for over one year without palpable LH. The epidermis and the subcutaneous tissue thickness of each region were examined using SSU. The presence of LH and associated risk factors for LH were evaluated. RESULTS We included 136 patients in our study. The mean age of all patients was 52.87±14.93 years, 59.6% were female and 73.5% had type 2 DM. The duration of DM and insulin usage were 15.76±9.20 and 11.42±8.26 years, respectively. The mean body mass index (BMI) of all patients was 30.59±7.40kg/m2. Non-palpable LH was detected in 87.5% (n=116) of the patients using SSU. In the multivariate logistic regression analyses, total cholesterol level, short-acting insulin dose and coronary artery disease (CAD) were associated with LH presence. CONCLUSION Non-palpable LH can be seen at high rates in patients who have multiple insulin injections. Palpation is likely not enough to detect LH and we believe it would be appropriate to evaluate the presence of LH using SSU, especially for those who need high-dose insulin to control hyperglycaemia.

Abstract
Introduction The history of insulin-induced skin lipohypertrophy (LH) runs parallel to that of insulin's 100 years, and an average of 47% of insulin-treated patients still suffer from it today. The metabolic and economic effects of LH are significant, with hypoglycemia being the most striking. The objective of the study was to perform a 52-week follow-up of 713 insulin-treated patients with type 2 diabetes (T2DM) and LH to detect any differences in the occurrence of hypoglycemic events (HYPOs) and related healthcare costs as well as in LH rates and injection habits between an intensive education intervention group (IG) and control group (CG) provided with a single educational session at the starting point. Methods All participants were trained in accurately self-monitoring blood glucose and recording all HYPOs for 6 months, which allowed baseline recordings before they were randomized into the IG, comprising 395 insulin-treated subjects undergoing repeated, structured multimodal education on correct injection techniques as a longstanding behavioral rehabilitation strategy, and the CG, comprising 318 subjects receiving the same structured, multimodal educational session, but only initially. Results Changes in LH rate and size and in performance were large in the IG and only slight and transient in the CG. A striking difference in the rate of decrease of HYPOs was also apparent between groups. Indeed, estimated costs of health interventions for severe and symptomatic HYPOs, which were on the order of €70,000 and €9300, respectively, in the two groups at baseline decreased by 5.9 times and 13.7 times, respectively, at the end of follow-up in the IG and by only approximately half in the CG. Full details of the changes occurring as a result of intensive education are provided in the text. Conclusions The effect of only initial education in the CG was not significant, thus providing evidence of the virtual worthlessness of a single training session on injection techniques, typical of worldwide daily clinical practice, and easily explaining the extremely high prevalence of LH in insulin-treated patients. Conversely, highly positive effects on LH prevalence and size as well as costs expected from decreased HYPO rate were obtained in the IG. To our knowledge, ours is the first 18-month randomized trial in the field. If our experimental model were to be used as an effective, longstanding behavioral rehabilitation strategy and therefore adapted to real-world settings universally, LH prevalence and costs related to their clinical consequences would be drastically reduced. However, only with a strong, relentless commitment of universities, scientific societies, and patient associations can we achieve this ambitious goal, which would provide great institutional savings and improved quality of life for people with diabetes.

Abstract
BACKGROUND Lipohypertrophy (LHT) has been suggested as an outcome of the adipogenic effects of insulin injection-related tissue trauma. It commonly occurs in the clinical setting, but the current understanding of LHT by the medical staff and diabetes patients remains insufficient; moreover, it has not garnered attention as a research topic. OBJECTIVE To investigate the ultrasound characterization of LHT, to identify the factors associated with LHT development by assessing the prevalence of LHT and compare the accuracy of clinical palpation with that of ultrasonography in LHT detection, and to further evaluate the possible impact of LHT on patients' blood glucose fluctuations. METHOD A cross-sectional study was conducted in 120 patients with type 2 diabetes. Patients' general information were obtained using a questionnaire, and the patients were evaluated for LHT by ultrasonography and clinical palpation of the abdomen. The patients were instructed to inject equal amounts of insulin in tissues with LHT and in normal adipose tissues (NATs) in two non-consecutive d in a selected week; the possible effect of LHT on patients' blood glucose fluctuations was assessed using a continuous glucose monitoring system. RESULTS LHT has characteristic ultrasonic signs. We found a high rate of missed LHT detection on clinical palpation compared with that on ultrasonography (P < 0.05). The duration of insulin treatment, rotation of injection sites, frequency of needle reuse, and number of insulin injections per day were the primary factors influencing the development of LHT (P < 0.05). Compared with NATs, LHT tissues showed extremely elevated amplitude of glycemic excursion, mean blood glucose levels, standard deviation of blood glucose levels and postprandial glucose excursion, and large fluctuations in blood glucose levels (P < 0.05). CONCLUSION Ultrasonography can more accurately detect LHT than can clinical palpation. LHT development is associated with several factors and can lead to significant fluctuations in blood glucose levels; thus, sufficient attention should be paid to investigating the underlying mechanism of LHT.

Abstract
PURPOSE The purpose of this systematic review was to assess potential gender differences in prevalence and clinical relevance of insulin-related lipohypertrophy (LH). PATIENTS AND METHODS Five electronic databases (PubMed, Embase, CNKI, Wanfang and VIP) were systematically searched for studies, from inception to 1st Sep 2022, on the prevalence of insulin-related LH. The eligibility of articles was independently screened, and the included studies were evaluated using standardized quality assessment tools. RESULTS A total of 22 studies mentioned the LH prevalence in different genders, of which two are about gestational diabetes; therefore, 20 studies were eventually included, providing data on 6238 patients. The prevalence of LH varied from 30.26% to 72.54%. Ten studies (4392 patients) were conducted with the adult diabetes patients of different genders over the age of 18, the total prevalence rate of LH was 51.73%, the LH prevalence in male gender was from 41.94% to 68.57% and the rate of the total population was 54.89% (2046 patients); The LH prevalence in female gender was from 33.18% to 70% and the rate of the total population was 48.98% (2346 patients), and the prevalence of LH was significantly different between male and female gender (P<0.001). Interestingly, only one study (n=1227) showed that there were dramatic differences between different genders (P<0.001), the subjects were T2DM patients, the LH prevalence rate of male vs female was 70.52% (299/424) VS 52.18% (419/803), while the other studies either only include T1DM or both T1DM and T2DM. CONCLUSION The evidence shows that the results of gender differences in the LH prevalence are inconsistent with different types of DM. Probably, there is no gender differences in the LH prevalence in adult patients with T1DM, but it has a gender difference between male and female in T2DM. More strictly designed clinical studies are needed to further verify and reveal the underlying mechanisms.

Abstract
BACKGROUND Lipohypertrophy (LH) of subcutaneous tissue is an insulin-induced complication occurring in patients with diabetes. We aimed to define the prevalence of LH and identify its risk factors in type 1 diabetes (T1DM) patients treated with continuous subcutaneous insulin infusion (CSII). MATERIALS AND METHODS The study included 79 consecutive CSII-treated T1DM patients. The diagnose of LH was based on ultrasonography (US) as a reference method, physical examination was also performed. Clinical characteristics were available from the medical records. RESULTS The median age of patients was 28 years (interquartile range [IQR], 24-30.5) with a body mass index (BMI) of 24.5 ± 3.5 kg/m2, HbA1c 7.1% (IQR, 6.7-8.1), T1DM duration 15 (9-20) years, and CSII use duration of 8 year (IQR, 5-11). LH was detected by US in 75 (94.9%) patients. This value was much higher than this obtained by visual assessment (n = 39, 49.4%) or palpation (n = 59, 74.7%). In univariate analyses, the following risk factors for occurrence of 5 and more LH lesions were identified: the ratio of insulin dose to body mass exceeding 0.7 IU/kg (OR, 3.69; 95% CI, 1.43-10.01) and the total daily insulin dose (OR, 1.05; 95% CI, 1.02-1.09). A higher dose of insulin per kg remained a significant risk factor of LH amount in multivariate analysis. CONCLUSION This selected T1DM cohort treated with CSII had a very high prevalence of LH. US assessment should be considered as a reference method for LH screening in T1DM patients. The identified risk factors for the number of LH lesions were related to insulin dosing.

Abstract
INTRODUCTION Studies on the durability of an intensive, structured education protocol on best insulin injection practice are missing for people with type 2 diabetes mellitus (T2DM). The aim of this study was to assess the durability of an intensive, structured education-based rehabilitation protocol on best insulin injection practice in well-trained subjects from our previous intensive, multimedia intervention study registered as the ISTERP-1 study. A total of 158 subjects with T2DM from the well-trained group of the 6-month-long ISTERP-1 study, all of whom had successfully attained lower glucose levels compared to baseline levels with lower daily insulin doses and with less frequent and severe hypoglycemic episodes, participated in the present investigation involving an additional 6-month follow-up period, called the ISTERP-2 study. METHODS Participants were randomized into an intervention group and a control group, depending on whether they were provided or not provided with further education refresher courses for 6 months. At the end of the 6 months, the two groups were compared in terms of injection habits, daily insulin dose requirement, number of severe or symptomatic hypoglycemic events, and glycated hemoglobin (HbA1c) levels. RESULTS Despite being virtually superimposable at baseline, the two groups behaved quite differently during the follow-up. The within-group analysis of observed parameters showed that the subjects in the intervention group maintained and even improved the good behavioral results learned during the ISTERP-1 study by further reducing both the rate of injection technique errors (p < 0.001) and size of lipohypertrophic lesions at injection sites (p < 0.02). Conversely, those in the control group progressively abandoned best practice, except for the use of ice-cold insulin and, consequently, had significantly higher HbA1c levels and daily insulin dose requirements at the end of the follow-up than at baseline (p < 0.05). In addition, as expected from all the above, the rate of hypoglycemic episodes also decreased in the intervention group (p < 0.05), resulting in a significant difference between groups after 6 months (p < 0.02). CONCLUSION Our data provide evidence that intensive, structured education refresher courses have no outstanding durability, so that repeated refresher courses, at least at 6-month intervals, are needed to have positive effects on people with T2DM, contributing not only to prevention but also to long-term rehabilitation.

Abstract
INTRODUCTION Insulin, which is used in the treatment of diabetes mellitus (DM), may lead to the development of lipohypertrophy (LH) which can negatively affect the management of diabetes mellitus. Two common methods to detect LH are palpation and superficial subcutaneous ultrasonography (SSU). We investigated the frequency of non-palpable LH using SSU, as well as examining risk factors. METHOD We included in our study patients who had been receiving insulin injections at least twice a day for over one year without palpable LH. The epidermis and the subcutaneous tissue thickness of each region were examined using SSU. The presence of LH and associated risk factors for LH were evaluated. RESULTS We included 136 patients in our study. The mean age of all patients was 52.87±14.93 years, 59.6% were female and 73.5% had type 2 DM. The duration of DM and insulin usage were 15.76±9.20 and 11.42±8.26 years, respectively. The mean body mass index (BMI) of all patients was 30.59±7.40kg/m2. Non-palpable LH was detected in 87.5% (n=116) of the patients using SSU. In the multivariate logistic regression analyses, total cholesterol level, short-acting insulin dose and coronary artery disease (CAD) were associated with LH presence. CONCLUSION Non-palpable LH can be seen at high rates in patients who have multiple insulin injections. Palpation is likely not enough to detect LH and we believe it would be appropriate to evaluate the presence of LH using SSU, especially for those who need high-dose insulin to control hyperglycaemia.

Abstract
In the article recently published in Diab Res Clin Pract (1), we described one of the most exciting paths in the history of medicine from the perspective of diabetologists and people with type 1 diabetes. Such a history lasted 100 years, from the discovery of insulin to the most technologically advanced technologies aimed at making treatment as close to physiology and user-friendly as possible. Indeed, we are luckier than others because, by living in Italy and the USA, respectively, we have access to miniaturized and computerized insulin delivery systems, but this is not the case worldwide. Due to that, while receiving many favorable comments from colleagues and friends, we were encouraged to further expand on the issue and go deeper into insulin injection technique.

Abstract
INTRODUCTION The alarming increase in type 2 diabetes mellitus (T2DM) in Saudi Arabia is aggravated by increasing obesity, sedentary lifestyle, and population aging. The RIMODIS study aimed at describing the practices in the therapeutic management of patients with T2DM treated with different insulin regimens. METHODS This national, multicenter, non-interventional, cross-sectional disease registry on the real-life therapeutic management of insulin-treated patients with T2DM in Saudi Arabia enrolled 3010 patients. It primarily aimed at describing treatment patterns, complications, and glycemia levels. Patients completed the diabetes treatment satisfaction questionnaire (DTSQ). Data on different treatment patterns were analyzed using chi-square or Fisher's exact test. Outcomes were analyzed according to the different insulin regimen subgroups (basal versus premixed). RESULTS Over 60% of patients were treated with premixed insulin and most patients were also prescribed oral antidiabetics (OADs). Patients on insulin alone seemed to achieve better glycated hemoglobin (HbA1c) control. Adding OADs to insulin slightly increased treatment satisfaction scores, with scores higher in patients on basal insulin compared to premixed insulin. Hypoglycemia was lower when adding OADs to insulin. Most patients showed high treatment adherence; however, two-thirds of study patients failed to achieve glycemic target levels. CONCLUSION Most patients are treated with a combination of insulin and OADs, associated with glycemic control and low incidence of hypoglycemia. However, we highlight suboptimal glycemic target achievement, underscoring the need to improve T2DM clinical management and promote healthier lifestyle among patients in Saudi Arabia.

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

Abstract
INTRODUCTION It is essential to use the correct injection technique (IT) to avoid skin complications such as lipohypertrophy (LH), local inflammation, bruising, and consequent repeated unexplained hypoglycemia episodes (hypos) as well as high HbA1c (glycated hemoglobin) levels, glycemic variability (GV), and insulin doses. Structured education plays a prominent role in injection technique improvement. The aim was to assess the ability of structured education to reduce (i) GV and hypos, (ii) HbA1c levels, (iii) insulin daily doses, and (iv) overall healthcare-related costs in outpatients with T2DM who were erroneously injecting insulin into LH. METHODS 318 patients aged 19-75 years who had been diagnosed with T2DM for at least 5 years, were being treated with insulin, were routinely followed by a private network of healthcare centers, and who had easily seen and palpable LH nodules were included in the study. At the beginning of the 6-month run-in period (T-6), all patients were trained to perform structured self-monitoring of blood glucose and to monitor symptomatic and severe hypos (SyHs and SeHs, respectively). After that (at T0), the patients were randomly and equally divided into an intervention group who received appropriate IT education (IG) and a control group (CG), and were followed up for six months (until T+6). Healthcare cost calculations (including resource utilization, loss of productivity, and more) were carried out based on the average NHS reimbursement price list. RESULTS Baseline characteristics were the same for both groups. During follow-up, the intra-LH injection rate for the CG progressively decreased to 59.9% (p < 0.001), a much smaller decrease than seen for the IG (1.9%, p < 0.001). Only the IG presented significant decreases in HbA1c (8.2 ± 1.2% vs. 6.2 ± 0.9%; p < 0.01), GV (247 ± 61 mg/dl vs. 142 ± 31 mg/dl; p < 0.01), insulin requirement (- 20.7%, p < 0.001), and SeH and SyH prevalence (which dropped dramatically from 16.4 to 0.6% and from 83.7 to 7.6%, respectively; p < 0.001). In the IG group only, costs-including those due to the reduced insulin requirement-decreased significantly, especially those relating to SeHs and SyHs, which dropped to €25.8 and €602.5, respectively (p < 0.001). CONCLUSION Within a 6-month observation period, intensive structured education yielded consistently improved metabolic results and led to sharp decreases in the hypo rate and the insulin requirement. These improvements resulted in a parallel drop in overall healthcare costs, representing a tremendous economic advantage for the NHS. These positive results should encourage institutions to resolve the apparently intractable problem of LH by financially incentivizing healthcare teams to provide patients with intensive structured education on proper injection technique.

Abstract
INTRODUCTION Despite the availability of sophisticated devices and suitable recommendations on how to best perform insulin injections, lipohypertrophy (LH) and bruising (BR) frequently occur as a consequence of improper injection technique. AIM The purpose of this nationwide survey was to check literature-reported LH risk factors or consequences for any association with BR METHOD: This was a cross-sectional, observational, multicenter study based on the identification of skin lesions at all patient-reported insulin injection sites in 790 subjects with diabetes. General and injection habit-related elements were investigated as possible BR risk factors. RESULTS While confirming the close relationship existing between LH and a full series of factors including missed injection site rotation, needle reuse, long-standing insulin treatment, frequent hypoglycemic events (hypos), and great glycemic variability (GV), the observed data could find no such association with BR, which anyhow came with high HbA1c levels, missed injection site rotation, and long-standing insulin treatment. CONCLUSION BR most likely depends on the patient's habit of pressing the injection pen hard onto the skin. Despite being worrisome and affecting quality of life, BR seems to represent a preliminary stage of LH but does not affect the rate of hypos and GV. TRIAL REGISTRATION 207/19.09.2017.

Abstract
AIMS Subclinical lipohypertrophy is a lesion meeting ultrasonic criteria for lipohypertrophy that was not detected by inspection and palpation. Little information is published on subclinical lipohypertrophy among insulin injection people with diabetes. We aimed to investigate the subclinical lipohypertrophy prevalence, risk factors, and the association between subclinical lipohypertrophy and glycemic control. METHODS This observational study included 316 people with diabetes who had continuously received insulin therapy for at least one year. We performed ultrasound scanning and clinical examination for evidence of subclinical lipohypertrophy. Demographic characteristics, clinical information, and glycated hemoglobin were measured. RESULTS The overall prevalence of subclinical lipohypertrophy was 19.9%. By stepwise logistic regression, higher BMI (OR = 1.44, 95%CI: 1.15-1.81, P = 0.002), incorrect rotation of sites (OR = 3.11, 95%CI: 1.02-9.47, P = 0.046), insulin needle reusage for more than four times (OR = 10.00, 95%CI: 3.23-31.02, P = 0.000) and type 1 diabetes (OR = 6.33, 95%CI: 1.32-30.47, P = 0.021) remained associated with subclinical lipohypertrophy. Subclinical lipohypertrophy demonstrated a significant independent correlation with the nonoptimal glycemic control (OR = 9.97, 95% CI: 3.46-28.75, P = 0.000) when accounting for demographic and diabetes-related parameters. CONCLUSIONS Subclinical lipohypertrophy is common among insulin-injecting patients with diabetes and is related to glycemic control deterioration. Ultrasonography may be an ideal adjunct in the evaluation of easily ignored lipohypertrophy lesions, especially where poor glycemic control, incorrect injection behaviors, overweight or obesity are documented.

Abstract
INTRODUCTION The aim of this randomized controlled trial was to assess the impact of providing intensive injection technique (IT) education to patients routinely injecting insulin into sites of lipohypertrophy (LH). METHODS Between November 2016 and May 2018, insulin-injecting patients with LH treated at Tianjin Metabolism Hospital (a public tertiary medical institution), Tianjin, China, were included in a 6-month prospective randomized controlled trial and randomized into either the intervention (the IT-education group) or the control (control group) arm. The control and IT-education groups were seen by different groups of trained nurses on different clinic days. IT education emphasized moving injections to normal tissue sites, within-and between-site injection rotation, an initial reduction of insulin total daily dose (TDD), and stopping needle reuse. Needles were provided to the IT group, while controls acquired needles in their usual way. Differences in changes in glycated hemoglobin (HbA1c) and insulin TDD were the primary and main secondary endpoints, respectively. RESULTS The control (n = 104) and IT-education (N = 106) groups had similar demographic parameters (97% with type 2 diabetes) and baseline IT behavior. HbA1c reduction was similar in the IT-education and control group in the intention-to-treat (ITT) analysis (6-month between-group difference 0.16% [1.7 mmol/mol], 95% confidence interval [CI] - 0.11, 0.43 [- 1.2, 4.7]; p = 0.239) but was significant by the per-protocol (PP) analysis (difference 0.31% [3.4 mmol/mol], 95% CI 0.02, 0.60 [0.2, 6.6]; p = 0.038). Changes in TDD insulin in the IT-education group were approximately - 7 and - 8 IU by the ITT and PP analyses, respectively, versus - 1 IU (nonsignificant) in the controls (both between-group differences p ≤ 0.05). Despite the study design, IT education "contamination" (unplanned adoption of IT-intervention behaviors) was documented in 63 control patients. By post hoc analyses, HbA1c in "contaminated" controls decreased by 0.70% (7.7 mmol/mol) vs. 0.20% (2.2 mmol/mol) in "non-contaminated' patients (p = 0.019) at 6 months. CONCLUSIONS Proper IT, including learning to not inject into sites of LH, proper within- and between site rotation, needle reuse reduction, and the use of 4-mm, 32-G needles in Chinese patients injecting into sites of LH enables a safe reduction of TDD insulin while maintaining overall glycemic control.

Abstract
BACKGROUND The number of older adults with insulin-treated diabetes mellitus (DM) is steadily increasing worldwide. Errors in the insulin injection technique can lead to skin lipohypertrophy (LH), which is the accumulation of fat cells and fibrin in the subcutaneous tissue. While lipohypertrophic lesions/nodules (LHs) due to incorrect insulin injection techniques are very common, they are often flat and hardly visible and thus require thorough deep palpation examination and ultrasonography (US) for detection. Detection is crucial because such lesions may eventually result in poor diabetes control due to their association with unpredictable insulin release patterns. Skin undergoes fundamental structural changes with aging, possibly increasing the risk for LH. We have therefore investigated the effect of age on the prevalence of LHs and on factors potentially associated with such lesions. METHODS A total of 1227 insulin-treated outpatients with type 2 DM (T2DM) referred to our diabetes centers were consecutively enrolled in the study. These patients underwent a thorough clinical and US evaluation of the skin at injection sites, as previously described, with up to 95% concordance betweenthe clinical and US screening techniques. Of these 1227 patients, 718 (59%) had LH (LH+) and 509 (41%) were LH-free (LH-). These patients were then assigned to two age class groups (≤ 65 years and > 65 years), and several clinical features, diabetes complication rates, and injection habits were investigated. RESULTS Comparison of the two age subgroups revealed that 396 (48%) and 322 (79%) patients in the younger and older groups, respectively, had LHs (p < 0.001). Compared to the younger subgroup, the older subgroup displayed a higher LH rate in the abdomen (52.9 vs. 38.3%; p < 0.01) and a lower rate in the arms (25.4 vs. 35.8%; p < 0.05), thighs (26.7 vs. 33.4%; p < 0.05), and buttocks (4.9 vs. 26.2%; p < 0.01). In older subjects, the most relevant parameters were: habit of injecting insulin into LH nodules (56 vs. 47% [younger subjects]; p < 0.01), rate of post-injection leakage of insulin from injection site (drop-leaking rate; 47 vs. 39% [younger subjects]; p < 0.05), and rate of painful injections (5 vs. 16% [younger subjects]; p < 0.001). Multivariate analysis showed a stronger association between LH and poor habits, as well as between several clinical parameters, among which the most relevant were hypoglycemic events and glycemic variability. DISCUSSION The higher rate of post-injection drop-leaking and pain-free injections might find an explanation in skin changes typically observed in older adults, including lower thickness, vascularity and elasticity, and a more prominent fibrous texture, all of which negatively affect tissue distensibility. Consequently, in addition to the well-known association between aging skin impaired drug absorption rate, aging skin displays a progressively decreasing ability to accommodate large volumes of insulin-containing fluid. CONCLUSIONS The strong association between LH rate and hypoglycemic events plus glycemic variability suggests the need (1) to take specific actions to prevent and control the high risk of acute cardiovascular events expected to occur in older subjects in the case of hypoglycemic events, and (2) to identify suitable strategies to fulfill the difficult task of performing effective educational programs specifically targeted to the elderly.

Abstract
INTRODUCTION Lipohypertrophies (LHs) due to incorrect insulin injection techniques have been described in the literature for decades. Their rate averages 38%, but this is still controversial because of the vast range reported by different publications, most of which fail to describe the selected detection protocol and therefore are not entirely reliable. We still need to identify the real LH rate, and only consistently using a standardized method in a large cohort of insulin-treated (IT) patients make this possible. METHODS Our group performed thorough clinical skin examinations on patients suffering from type 2 diabetes mellitus (T2DM): 1247 IT T2DM outpatients were examined according to a standardized protocol, previously published elsewhere, as well as an ultrasound scan of the same skin areas to assess the degree of concordance between the two methods and to evaluate the demographic, clinical, and behavioral risk factors (RF) as well as metabolic consequences of identified LHs. RESULTS The concordance between the two methods was 99%. Identified risk factors for LHs were needle reuse, failure to rotate injection sites, and ice-cold insulin injections. High HbA1c values, wide glycemic variability, and longstanding proneness to hypoglycemia with a high rate of ongoing hypoglycemic events proved to be significantly associated with LHs, too; the same applied to cardiovascular and renal complications as well as to living alone and being retired. CONCLUSIONS Based on a strict well-structured methodology, our data confirmed what has already been reported in the literature on factors leading to, or associated with, LHs and, for the first time in adults, indicated cryotrauma from ice-cold insulin injections and specific social conditions as factors facilitating LH occurrence. HCPs should therefore plan a yearly clinical examination of all injection sites to improve patient quality of life through better glucose control and a reduced rate of hypoglycemic events.

Abstract
Diabetes Mellitus (DM) is the most common cause of renal failure and ESRD all over the world, and often requires an individualized insulin treatment regimen. Malnutrition, depression-related eating behavior changes, high on-off-dialysis day-to-day glycemic variability and frequent hypoglycemic events occurring during or immediately after dialysis make it hard to identify best insulin dosage in hemodialyzed patients. This suggests a prudent attitude including non-stringent control, despite which repeated hypoglycemia quite often occurs in such patients. When looking for possible sources of hypoglycemia, health professionals too often overlook the identification of skin lipodystrophy (LD) due to an incorrect insulin injection technique. This mini-review focuses on the high frequency (57%) of LD in a cohort of 1004 insulin-treated people with DM on dialysis consecutively referring to our joint medical centers, and on its relationship with hypoglycemia and glycemic control/variability. When taking on such patients, care team members accept to face a complex disease burdened with several risk factors requiring high professional skills, and have to keep in mind also the possible presence of any LD areas eventually interfering with expected results. A timely educational intervention on the correct injection technique can help reduce the high risk of hypoglycemia and large glycemic variability in dialysed people with DM.

Abstract
INTRODUCTION End-stage renal disease (ESRD) is associated with increased cardiovascular mortality (CVM) and diabetes mellitus (DM), which in many cases is treated with insulin. Skin lipohypertrophy (LH) very often occurs in insulin-treated (IT) patients as a consequence of inadequate injection technique and is one of the most prominent contributors to hypoglycemia (HYPO), glycemic variability (GV), and poor metabolic control (PMC). METHOD The aim of our multicenter observational study was to assess LH prevalence at self-injection sites and any possible factors predicting high LH/HYPO rates and GV in 296 dialyzed ITDM patients characterized by 64 ± 7 years of age, 7 ± 2 years disease duration, 2.6 ± 2.2 years dialysis duration, preferred pen utilization (80%), and basal-bolus regimen (87.4%) with self-injections (62.6%) largely surpassing caregiver-assisted ones (16.9%), and a mix of the two injection methods (20.5%). RESULTS LH was detected in 57% of patients. Univariate analysis followed by backwards stepwise multivariate logistic regression function showed increased odds for developing LH in patients characterized by needle reuse, smaller injection areas, missed injection site rotation, higher HbA1c levels, and more prominent rates of HYPO and GV. CONCLUSION This was the first time such observation was made. It is now time for further studies aimed at providing evidence also in ESRD ITDM patients for the cause-effect relationship among wrong injection behavior, LH, and poor metabolic control and for the long-term preventative role of suitable educational countermeasures.
