[PMID: 38515401 PMCID: PMC10962293 DOI: 10.1080/10717544.2024.2329100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Accepted: 02/29/2024] [Indexed: 03/23/2024] Open
Abstract
The local injection of therapeutic drugs, including cells, oncolytic viruses and nucleic acids, into different organs is an administrative route used to achieve high drug exposure at the site of action. However, after local injection, material backflow and side effect reactions can occur. Hence, this study was carried out to investigate the effect of gelatin on backflow reduction in local injection. Gelatin particles (GPs) and hydrolyzed gelatin (HG) were injected into tissue models, including versatile training tissue (VTT), versatile training tissue tumor-in type (VTT-T), and broiler chicken muscles (BCM), using needle gauges between 23 G and 33 G. The backflow material fluid was collected with filter paper, and the backflow fluid rate was determined. The backflow rate was significantly reduced with 35 μm GPs (p value < .0001) at different concentrations up to 5% and with 75 μm GPs (p value < .01) up to 2% in the tissue models. The reduction in backflow with HG of different molecular weights showed that lower-molecular-weight HG required a higher-concentration dose (5% to 30%) and that higher-molecular-weight HG required a lower-concentration dose (7% to 8%). The backflow rate was significantly reduced with the gelatin-based formulation, in regard to the injection volumes, which varied from 10 μL to 100 μL with VTT or VTT-T and from 10 μL to 200 μL with BCM. The 35 μm GPs were injectable with needles of small gauges, which included 33 G, and the 75 μm GPs and HG were injectable with 27 G needles. The backflow rate was dependent on an optimal viscosity of the gelatin solutions. An optimal concentration of GPs or HG can prevent material backflow in local injection, and further studies with active drugs are necessary to investigate the applicability in tumor and organ injections.

Abstract
Type 2 diabetes (T2D) is characterized by low-grade inflammation. Low-density neutrophils (LDNs) represent normally less than 2% of total neutrophils but increase in multiple pathologies, releasing inflammatory cytokines and neutrophil extracellular traps (NETs). We assessed the count and role of high-density neutrophils (HDNs), LDNs, and NET-related activities in patients with T2D. HDNs and LDNs were purified by fluorescence-activated cell sorting (FACS) and counted by flow cytometry. Circulating inflammatory and NETs biomarkers were measured by ELISA (Enzyme Linked Immunosorbent Assay). NET formation was quantified by confocal microscopy. Neutrophil adhesion onto a human extracellular matrix (hECM) was assessed by optical microscopy. We recruited 22 healthy volunteers (HVs) and 18 patients with T2D. LDN counts in patients with diabetes were significantly higher (160%), along with circulating NETs biomarkers (citrullinated H3 histone (H3Cit), myeloperoxidase (MPO), and MPO-DNA (137%, 175%, and 69%, respectively) versus HV. Circulating interleukins (IL-6 and IL-8) and C-Reactive Protein (CRP) were significantly increased by 117%, 171%, and 79%, respectively, in patients compared to HVs. Isolated LDNs from patients expressed more H3Cit, MPO, and NETs, formed more NETs, and adhered more on hECM compared to LDNs from HVs. Patients with T2D present higher levels of circulating LDN- and NET-related biomarkers and associated pro-inflammatory activities.

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.

Evaluation of Lipohypertrophy in Patients With Type 1 Diabetes Mellitus on Multiple Daily Insulin Injections or Continuous Subcutaneous Insulin Infusion. Endocr Pract 2023; 29:119-126. [PMID: 36423861 DOI: 10.1016/j.eprac.2022.11.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 11/10/2022] [Accepted: 11/15/2022] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To determine lipohypertrophy (LH) in patients with type 1 diabetes mellitus (T1DM) on multiple daily insulin injections (MDII) or continuous subcutaneous insulin infusion (CSII) and to reveal the factors associated with the development and severity of LH. METHODS Sixty-six patients with T1DM treated with MDII (n = 35, 53%) or CSII (n = 31, 47%) for at least 1 year were included. LH localizations were detected with palpation and ultrasonography (USG). RESULTS The LH detection rate with USG was significantly higher than that by palpation in the whole group (P < .001). The LH was detected with USG in 30 (85.7%) patients in the MDII group and 22 (71.0%) patients in the CSII group (P = .144). Advanced LH was detected in 13 (37.1%) of the patients treated with MDII and in 3 (9.7%) of the patients treated with CSII. LH was more severe in the MDII group than in the CSII group (P = .013). Diabetes duration and length of infusion set use were significantly longer and body mass index, hypoglycemia, and complication rates were higher in patients with LH than those in patients without LH (P < .05). A positive correlation was found between LH severity and HbA1C and insulin dose (P < .05, for both). MDII as insulin administration method, incorrect rotation, and a history of ketosis were found to be the most related factors with LH severity in a multiple linear regression analysis (P < .05). CONCLUSION USG might be an effective approach for detecting and evaluating the severity of LH. MDII might cause more severe LH than CSII in patients with T1DM. In this study, LH was found to be associated mostly with incorrect rotation technique and a history of ketosis.

Abstract
BACKGROUND The appropriate insulin injection skill is essential for optimal blood sugar control in patients with diabetes. However, the art of insulin injection is still not well understood in numerous medical centers. OBJECTIVES This study was designed to determine the association between appropriate insulin injection and blood glucose control in patients with type 2 diabetes in Yazd, Iran. METHODS This cross-sectional study was conducted on 301 patients with type 2 diabetes who referred to Diabetes Research Center in Yazd within August 2020 to February 2021. Based on simple random sampling, the subjects with inclusion criteria, such as age >18 years, using an insulin pen for at least 3 months, and self-injection, were selected. The insulin injection technique was evaluated by a 13-item researcher-made questionnaire. The total score of this questionnaire was 26, and its validity and reliability were confirmed. The data were analyzed using SPSS software (version 20). RESULTS The mean age of the participants was 59.83 ± 10.26 years, and 60.1% had primary school or less education. Most participants (87%) used a needle more than five times, and almost half of them (53.5%) did not rotate the injection sites properly. The patients who reported pain during injection had statically lower injection scores than others (17.90 vs. 19.38, P = 0.001). There was a significant negative correlation between insulin injection score with fasting blood sugar (β = -0.232, P < 0.001), two-hour postprandial glucose (β = -0.164, P = 0.005), and hemoglobin A1c (HbA1c) level (β = -0.263, P < 0.001). CONCLUSIONS None of the patients in this study fully followed the principles of a proper injection, which can lead to pain during injection, lipohypertrophy, hyperglycemia, and increased HbA1c levels.

Abstract
INTRODUCTION There is growing interest in the development of multiple presentations for biological products for subcutaneous (SC) injection for life cycle management and product differentiation. Bridging clinical studies are required to extrapolate the existing data package to new presentations. AREAS COVERED This review compiles information of bridging clinical studies conducted for biological products administered by the SC route and approved in more than one presentation by the United States Food and Drug Administration's Center for Drug Evaluation and Research up until 31 December 2021. Information regarding indication(s), presentation(s), approval pathways, approval timelines, and various aspects of bridging clinical studies was collected from published documents. EXPERT OPINION The type of bridging clinical study can depend on the extent of differences between presentations, existing data packages, and the stage of the product development. Design of a bridging clinical study should be based on the characteristics of a biological product and should be aimed at detecting the relevant differences between presentations. Single-dose comparative pharmacokinetics in normal healthy volunteers is the most common bridging clinical study design. Covariates like body weight and injection site should be considered during the design of these studies. The impact of the different user interfaces of presentations should also be considered.

Abstract
BACKGROUND Children with type 1 diabetes (T1D) take multiple subcutaneous injections of insulin daily to survive. It is controversial whether the insulin needles can be reused safely or not. This study assesses the effect of the reuse versus single-use of insulin needle on glycaemic control and injection-related complications. METHODS Nearly 121 children (<15 years) with T1D were prospectively observed for existing practice of needle reuse for first 3 months and then were asked to practice single-use for the next 3 months. RESULTS It was found that 78% participants were reusing needles more than three times. After 3 months of needle reuse, 91.3% patients had lipodystrophy. Frequency of reuse positively correlated with local redness, bleeding and leakage of insulin. The patients achieving HbA1c ≤7.5% was significantly low among those reusing needles more than four times. After 3 months of single-use, no significant difference was found in mean HbA1c. However, hyperglycaemic episodes, lipodystrophy and local complications reduced significantly. There was a significant reduction in mean HbA1c among those using needles more than six times earlier. CONCLUSION Reuse of insulin needles up to six times does not affect the glycaemic control significantly. To achieve target HbA1c (<7.5%) the needle reuse should be restricted to three times only, which can also reduce injection-related local complications.

Abstract
BACKGROUND Subcutaneous insulin therapy is associated with important injection site complications, which can influence insulin pharmacokinetics resulting in glycemic fluctuations above and below target levels for blood glucose. OBJECTIVE Our objective was to assess the prevalence and risk factors of cutaneous complications including insulin derived amyloidosis in insulin-injecting diabetes patients and to study the role of ultrasonography (in comparison to gel-assisted palpation) in early diagnosis of lipohypertrophy (LH). METHODS This was a cross-sectional study conducted at a tertiary care center in India, wherein 500 patients injecting insulin for ≥2 years were randomly enrolled and evaluated for the presence of cutaneous complications of insulin therapy through clinical examination, ultrasonography and punch biopsy of skin. RESULTS Clinical examination detected LH in 44.6% of patients. Ultrasonography diagnosed additional 13.4% of patients with LH which were missed on clinical examination. Incorrect rotation of sites (P < 0.001) and insulin syringe reusage for more than five times (P < 0.001) significantly increased the risk of LH. Skin biopsy was performed in 100 cases, out of which two patients showed apple green birefringence and its association with insulin was confirmed by positive staining with anti insulin antibody in these two patients. CONCLUSION Improper rotation of sites and reuse of needles were the leading causes of LH in Indian diabetic patients. Ultrasonography is more objective and reliable method of detecting LH. Insulin-derived amyloidosis may be a more common complication of insulin therapy than previously thought.

Abstract
Obesity is a major public health problem, and its trend is increasing worldwide. Interventions to effectively treat obesity and its related diseases are advocated. Given the complexity of obesity management, nurses need specific core skills to work in the Obesity Clinic and can act as key players in the multidisciplinary team of the Obesity Clinic. To provide practical guidelines for nurses working in Obesity Clinic for effective management of obesity and its related diseases, the current evidence on the role nurses in the obesity clinic was reviewed. Nurses can play a pivotal role in the management of patients with obesity and associated diseases that may require a stricter follow-up than usual care. Given the complexity of the treatment of obesity and its comorbidity, nurses should receive a specific training for: 1) methods and tools to effectively treat obesity and obesity-related disease, 2) patients and families education on nutrition, lifestyle changes, and prevention/management of obesity-related diseases; 3) motivation of patients towards adherence to treatment to achieve their specific goals. This manuscript highlights the need of specific core skills for nurses working in the Obesity Clinic.

Forst T, Choudhary P, Schneider D, Linetzky B, Pozzilli P. A practical approach to the clinical challenges in initiation of basal insulin therapy in people with type 2 diabetes. Diabetes Metab Res Rev 2021; 37:e3418. [PMID: 33098260 PMCID: PMC8519070 DOI: 10.1002/dmrr.3418] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2020] [Revised: 07/17/2020] [Accepted: 08/09/2020] [Indexed: 12/18/2022]
Abstract
Initiating insulin therapy with a basal insulin analogue has become a standard of care in the treatment of type 2 diabetes mellitus (T2DM). Despite increasing choices in pharmacological approaches, intensified glucose monitoring and improvements in quality of care, many patients do not achieve the desired level of glycaemic control. Although insulin therapy, when optimized, can help patients reach their glycaemic goals, there are barriers to treatment initiation on both the side of the patient and provider. Providers experience barriers based on their perceptions of patients' capabilities and concerns. They may lack the confidence to solve the practical problems of insulin therapy and avoid decisions they perceive as risky for their patients. In this study, we review recommendations for basal insulin initiation, focussing on glycaemic targets, titration, monitoring, and combination therapy with non-insulin anti-hyperglycaemic medications. We provide practical advice on how to address some of the key problems encountered in everyday clinical practice and give recommendations where there are gaps in knowledge or guidelines. We also discuss common challenges faced by people with T2DM, such as weight gain and hypoglycaemia, and how providers can address and overcome them.

Abstract
Monoolein-based cubic and hexagonal mesophases were investigated as matrices for insulin loading, at low pH, as a function of temperature and in the presence of increasing amounts of oleic acid, as a structural stabilizer for the hexagonal phase. Synchrotron small angle X-ray diffraction, rheological measurements, and attenuated total reflection-Fourier transform infrared spectroscopy were used to study the effects of insulin loading on the lipid mesophases and of the effect of protein confinement in the 2D- and 3D-lipid matrix water channels on its stability and unfolding behavior. We found that insulin encapsulation has only little effects both on the mesophase structures and on the viscoelastic properties of lipid systems, whereas protein confinement affects the response of the secondary structure of insulin to thermal changes in a different manner according to the specific mesophase: in the cubic structure, the unfolding toward an unordered structure is favored, while the prevalence of parallel β-sheets, and nuclei for fibril formation, is observed in hexagonal structures.

Abstract
Drug-device combination products should be safe and effective for intended uses by intended users under intended use environment during human factor (HF) studies. All known use errors and use-related problems should be considered during design of device and use-related risk analysis. Availability of such information in a compiled manner is scarce. This review compiles information of use errors reported during HF validation studies of biological combination products (drug + device) approved by USFDA's Centre for Drug Evaluation and Research between 21 June 2011 and 31 December 2019. Information regarding product, indication, type of devices, use errors, root causes and mitigation strategies were collected from published documents. Total 280 use errors were reported during HF validation studies of 39 devices across 5 categories. Overall approach and methodology for use error data collection during HF validation studies was in line with the US FDA recommendations. Performance of participants for critical and essential tasks was evaluated during HF validation studies via simulated use assessment, knowledge task assessment and interview. The root causes for use errors reported during HF validation studies were identified and use errors were mitigated by suitable corrective measures. Instructions for use clarification/improvement and labelling improvement were the most common mitigation strategies implemented across devices.

Abstract
BACKGROUND Insulin is an essential therapy for treating diabetes, but many patients lack standard insulin injection skills. PURPOSE We developed a standard training procedure based on a new simulation tool. Then we conducted a study to investigate the effect of this standard training on the ability of diabetic patients to inject themselves with insulin. METHODS After follow-up, a total of 120 patients with diabetes mellitus were included. These patients needed insulin therapy depending on their condition and had not previously learned insulin injection. We randomly divided them into the intervention group (60 cases) and the control group (60 cases). The control group was trained on insulin injection before being discharged according to the traditional method, and the intervention group was trained based on an improved simulation tool. All participants were trained as individuals or groups. Finally, we evaluated the learning effects of both groups. RESULTS The time spent at the training stage in the intervention group was shorter than the control group. We found that after applying simulation devices to mimic operations, the learning time for patients was reduced.The first subcutaneous injection success rate was 73.33% in the intervention group, which was significantly higher than that in the control group by 46.67%. The score of the first subcutaneous injection and pre-discharge score in the test group was significantly higher than that of the control group. One month later, the score for injection skills in the 2 groups was higher than that before discharge, and the score in the trial group was still higher than that in the control group. The incidence of subcutaneous fat hyperplasia in the trial group was lower than that in the control group (3.3% vs 15%, P < .05). Moreover, the incidence of hypoglycemia (16.7% vs. 26.7%) was higher in the control group, but the difference was not statistically significant (P = .184). CONCLUSIONS/IMPLICATIONS FOR PRACTICE After applying simulation tools plus operating video and guideline as the standard procedure to train diabetic patients on insulin injection, all patients had a good grasp of using the insulin injection technique. This education method is safe, efficient, and worth promoting worldly.

Abstract
In Japan, skin disinfection is typically considered necessary before an insulin injection to prevent infection at the injection site. This cross-sectional study evaluated factors that influenced symptoms of injection site infection among 238 Japanese patients who self-injected insulin for diabetes between October 2015 and January 2016. A structured questionnaire was used to collect data regarding skin disinfection practices, infection symptoms at the injection site, frequency of injections, environment at the time of injection, and hygiene habits. The majority of patients (83.2%) performed skin disinfection before the self-injection. Logistic regression analysis revealed that infection at the injection site was positively associated with skin disinfection before injection, age, and performing injections outside home. It was speculated that omitting skin disinfection before administering subcutaneous insulin injection was not the factor that affected the symptoms of injection site infection. The greatest contributor to infection symptoms was injections performed outside the home. Future studies focusing on the environment, in which patients administer insulin injections, to assess its influence on symptoms of injection site infections are warranted.

Abstract
BACKGROUND Diabetes mellitus is a common health problem worldwide. Proper insulin administration plays an important role in long term optimal blood sugar control. Adequate knowledge and attitude about insulin self-administration could also improve the management of diabetes and eventually improve the quality of life. This study aimed to assess knowledge, attitude and practice towards insulin self-administration and associated factors among diabetic patients at Zewditu Memorial Hospital (ZMH), Ethiopia. METHODS An institution-based cross-sectional study was conducted among 245 diabetic patients who were selected by systematic random sampling during follow-up at ZMH. The data was collected using an interviewer-administered structured questionnaire and analyzed by SPSS v.20. Binary logistic regression was used to identify associated factors of patients' knowledge and P < 0.05 was used to declare the association. RESULTS Among 245 patients enrolled, 53.9% were male with a mean age of 53.26 ±13.43 years and more than 84% of the patients can read and write. The overall patients' knowledge was 63.4%. Better knowledge was observed concerning timing (78.4%) and site of insulin injection (89.4%), while knowledge on the angle of inclination during insulin administration (43.3%) and complications of insulin therapy (49%) were low. Patients who were male gender, never married, government or NGO employees, urban residents, who completed elementary and higher education had a higher knowledge than their comparators. The majority (62%) of the study patients had a favorable attitude on insulin self-administration. Although the majority 177(72.2%) of the study patients have administered insulin themselves, only 120(49.0%) of the patients injected insulin appropriately at 450. Frequent repetition of the injection site was practiced among 176(71.8%) patients and 139(56.7%) injected insulin before or immediately after food intake. CONCLUSION Patients' knowledge and attitude seem suboptimal and malpractice of insulin self-administration was reported. Therefore, the gaps should be addressed through patient education and demonstration of insulin injection during each hospital visit.

Abstract
Purpose The main aim of this study was to explore how participants were practicing insulin injections and assess its association with the insulin related-outcomes. Methods A hospital-based cross-sectional study was conducted among 176 youngsters with diabetes in Tikur Anbesa Specialized Hospital, Ethiopia. The inclusion criterion was the use of insulin treatment for a minimum of one year. Data about insulin injection practices was derived from participants' report. Descriptive statistics was presented using frequency distributions and percentages for categorical variables while measure of central tendencies and dispersion for continuous variables. Chi-square test was employed to test for the association between compared variables. Results Participants were asked on how frequent they practice the appropriate insulin injecting practices. Based on that, eliminating air bubbles from a syringe, lifting skin fold during an injection, inserting a needle deep enough in the subcutaneous tissue, inspecting injection sites and self-monitoring of blood glucose were frequently done practices in more than 80% of the participants. Besides, over half of the participants reported that they frequently practice; insulin vial inspection, physical exercise, inject 1-3 cm apart from previous site, and insert a needle at 450. Regarding insulin storage, more than half of them store opened insulin in the refrigerator, though it is advisable to store it at room temperature. Appropriate injection site rotation was reported by nearly one-third of the participants. Questions such as; gentle re-suspension of cloudy insulin, adjust insulin dose when necessary and change insulin syringe at every injection were reported by very few of the participants. Coming to glycemic control of our study subjects, 83% of them had HgbA1C of above 7.5% (non-optimal) and 31% reported at least one episode of hypoglycemia. Non-optimal glycemic control was explained by poor injection site hygiene (p < 0.038) and infrequent inspection of injection sites (p < 0.049). Conclusion Compared to previous studies, this study came with higher proportion of participants who frequently practice the appropriate insulin injection practices. However, it is still important to educate patients on some crucial injecting practices.

Abstract
The requirement of in-person visits every 3 months for a health care provider to administer intramuscular depot medroxyprogesterone acetate (DMPA-IM) is a significant barrier to its use, particularly in the wake of the coronavirus pandemic. Time and travel costs as well as scheduling conflicts also negatively impact the receipt of subsequent contraceptive injections, which can result in unintended pregnancies. Subcutaneous depot medroxyprogesterone acetate (DMPA-SC) can be self-administered by individuals at home, expanding contraceptive access, convenience, and reproductive autonomy. With 30% less progestin, DMPA-SC improves upon the DMPA-IM formulation while retaining efficacy. As part of comprehensive contraceptive counseling, health care providers should consider offering DMPA-SC to eligible individuals interested in self-administration. Using a case study approach, evidence-based recommendations are reviewed for the off-label use of self-administered DMPA-SC in the United States.

Abstract
Although insulin delivery devices are widely used by the patients, there is a paucity of published guidelines to help professionals manage their patients in insulin therapies. To provide simple and easily implementable guidelines to health care physicians on the choice of insulin delivery devices in routine clinical practice, experts in diabetes gathered together and discussed the recommendations at the National insulin Summit 2018. An ideal insulin delivery device should accurately deliver the prescribed dose of insulin and be easy to use. Recommendations are: (1) insulin should be initiated by using an insulin device if the patient seems to discontinue insulin therapy. (2) Pen devices offer accurate dosing than a syringe and vial and are associated with cost savings in the long term. (3) Switching over from syringes and vial to disposable pen devices improves adherence. (4) FlexPen® offers better accuracy, and it requires lower dose force and injection force than SoloStar® and KwikPen® (5). Durable delivery pens such as NovoPen® 4 maintain accuracy and low dose force compared with vials and syringes. (6) One pen should be used by only one patient. (7) Regular counseling on the proper use of the pen device is required regularly. This consensus-based recommendation is a useful reference tool for health care practitioners to initiate insulin therapy in patients with diabetes by using the appropriate insulin pen device.

Abstract
OBJECTIVES User experience was compared between a new pre-fillable 2.25 mL glass syringe equipped with an ultra-thin-wall (UTW) 8 mm staked needle and a marketed BD Neopak™ syringe equipped with a special-thin-wall (STW) 12.7 mm staked needle. METHODS Participants simulated subcutaneous injections with both syringes alone (formative Human Factors study) and in combination with a needlestick-prevention device (validation Human Factors study). RESULTS Usability results of both studies showed higher success rates for delivering the full dose of 2 mL viscous solution (30 cP) with the 8mmUTW syringe than with the 12.7mmSTW one (63% vs. 42% in the formative study). The use of the 8mmUTW syringe demonstrated also better ease of use and acceptance results and 72% of formative study participants preferred this new syringe over the current one when delivering the viscous solution. Using a shorter needle also showed a benefit in decreasing the injection-related anxiety. Besides, in the case of a non-recommended injection technique, the calculated risk of accidental intramuscular injection is reduced by 2 to 13 times with the 8mmUTW syringe. CONCLUSION Altogether, the results obtained demonstrated an improvement of the user experience with this new syringe compared to the current one in the manual delivery of 2 mL viscous solutions.

Evaluating the effectiveness of a support programme for people with type 2 diabetes mellitus in primary care: an observational prospective study in Ecuador. BJGP Open 2020; 4:bjgpopen20X101025. [PMID: 32317264 PMCID: PMC7330222 DOI: 10.3399/bjgpopen20x101025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2019] [Accepted: 10/24/2019] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND The success of primary health care relies on the integration of empowered practitioners with cooperative patients regardless of socioeconomic status. Using resources efficiently would help to improve healthcare promotion and reduce complications of chronic non-communicable diseases (NCDs). The importance of network support programmes relies on the fact that they allow to accurately deliver medical care by shaping a sense of community and purpose among the patients. AIM To evaluate the effectiveness of a network support programme for patients with type 2 diabetes mellitus (T2DM). DESIGN & SETTING A centre-based observational prospective study took place in a primary care setting in Ecuador. METHOD The impact of the diabetes care programme was assessed by comparing initial and final metabolic characteristics and outcomes of 593 patients with T2DM, followed-up from April 2007 to December 2017, using paired sample t-test. Electrocardiograms (ECGs), ankle-brachial indexes (ABIs), ocular fundus, and monofilament neuropathy tests were assessed with the McNemar test to evaluate complications at the beginning and end of the study. RESULTS Glycated haemoglobin (HbA1c), lipid profile, and systolic blood pressure (SBP) showed statistically significant decreases between the initial measurement (IMs) and final measurements (FMs). In the FM, significantly lower HbA1c, diastolic blood pressure (DBP), and atherogenic index were found. Despite the length of time since diagnosis, during the follow-up time, long-term micro- and macro-vascular complications, such as ocular fundus, serum creatinine, and ABI, remained unchanged throughout the period of active participation in this healthcare programme. CONCLUSION This study demonstrates the feasibility of reducing plasma glucose, plasma lipids, and long-term complications in patients with T2DM by implementing a network support programme, which involves the medical team and patients themselves in an environment with limited resources.

Abstract
Background Selecting the appropriate insulin pen needle is important to reduce pain and injection-related adverse events like insulin leakage. It also helps to improve medication adherence and glycemic control in patients with type 1 diabetes mellitus (T1DM). Objective This study aimed to compare the 6-mm and 8-mm 32.5-gauge insulin pen needles in terms of glycemic control, pain score, user preference, medication adherence, and injection adverse events in patients with T1DM. Methods We conducted a prospective cohort study of 62 patients with T1DM. All patients constituted an experimental group initially and then changed the length of the needle to be part of a self-control group. The glycemic control, visual analog scale (VAS) pain score, Morisky Medication Adherence Scale (MMAS) score, needle attribute score, and injection-related adverse events were measured for all patients with both lengths of needles. Patients were assessed at the baseline visit and followed up for three months. Statistical comparisons were done by the chi-squared test, paired t-test, and paired Wilcoxon test when appropriate with a two-tailed alpha level below 0.05 indicating statistical significance. Results With the NanoPass® 32.5-gauge, 6-mm needle (Terumo Corp., Tokyo, Japan), patients had significantly lower glycated hemoglobin (HbA1c) compared to 8-mm needles (7.9% vs. 8.3%; p<0.001). The proportions of patients who reported no hypoglycemic episodes were 22/62 and 9/62, with the 6-mm and 8-mm needles, respectively. The 6-mm needles were better in terms of the following parameters compared to 8-mm needles: mean needle attribute scores (36.7 vs. 24.2; p<0.001), median VAS pain scores (20 vs. 55; p<0.001), insulin leakage (6/62 vs. 20/62; p=0.002), and the MMAS score (4.9 vs. 3.4; p<0.001). Conclusion This study provided an overview of the safety, adherence, pain score, and glycemic control relating to the 6-mm and 8-mm insulin needle lengths. Insulin injections using the NanoPass 32.5-gauge, 6-mm needle were associated with lower pain score, higher patient adherence, fewer adverse events, and better glycemic control compared to the 8-mm needle. Therefore, we recommend the use of the NanoPass 6-mm needle for patients with T1DM. Further studies are needed to confirm these findings in patients with type 2 diabetes mellitus (T2DM).

Abstract
Insulin infusion pump, continuous glucose monitoring (CGM), and insulin infusion set (IIS) have been developed to be increasingly feasible for people with type 1 diabetes (T1D). Several recently approved CGMs are transitioning from 7-day to 10-day wear time without the need for fingerprick recalibration. Nevertheless, studies and improvements on IIS, a critical part of insulin pump therapy, have been limited. In particular, the recommended wear time of IIS is still 2-3 days, which can hardly match the current duration of CGM for potential closed-loop system development. It is generally believed that both the inserted catheter and the subsequent infused insulin drug could induce particular subcutaneous tissue response and skin-related complications at the infusion site. In certain cases, poor glycaemic control, increased risk of hypoglycemia, and serious cosmetic impact on people with diabetes were observed. Skin complication has also been attributed as an important factor resulting users to discontinue insulin pump therapy. This article provides the rare systematic review of IIS induced subcutaneous tissue responses and skin complications, including the impacts from the inserted catheters, the subcutaneous infused insulin, and the adhesive or tape used to immobilize the catheter. The FDA's recommendation for the frequency of IIS change was further discussed. Future studies on this topic are required to further understand the IIS-related problems, and future strategies could be developed accordingly to significantly reduce the incidence of these problems, extend the wear time, and increase the acceptance of insulin pump based therapy.

Abstract
Biologic-device combination products using prefilled syringes (PFSs) and autoinjectors (AIs) are popular for biological products administered subcutaneously. Pharmacokinetic (PK) comparability studies commonly provide the scientific data to support introduction of AI presentations via bridging with PFS. A survey of biological products approved by FDA's Center for Drug Evaluation and Research identified 17 biologics license applications (BLAs) with both PFS and AI presentations for subcutaneous (SC) administration, including 16 approved on February 1, 2018, and one with AI presentation under review. A systematic review on the device parameters and the PK comparability studies bridging the two presentations was conducted. Subsequently, whether device parameters or the PK study design may have influenced the PK comparability study results was evaluated. The reported device parameters for AI and PFS are generally consistent across BLAs, whereas the approach to assess PK comparability varied, including the study design. Most PK comparability studies met bioequivalence (BE) criteria. Upon inspection of the studies that did not meet BE criteria, injection depth of AI and the injection site for either AI or PFS were identified as potential influencing factors to the outcome of PK comparability study. This study represents an initial attempt to identify the potential influencing factors on device bridging, including the characteristics of the device and the clinical pharmacology study. These findings may inform the combination product development strategy, specifically design considerations for device and PK comparability studies.

Abstract
BACKGROUND Adalimumab is administered via a pre-filled syringe or spring-loaded pen. In a previous study in Crohn's disease, higher drug levels were observed in syringe users. The aim of this study was to evaluate the impact of delivery device on adalimumab drug levels in patients with Crohn's disease. METHODS Consecutive Crohn's disease patients treated with maintenance adalimumab [40 mg fortnightly] were recruited from five centres. The first recorded drug level with matched clinical and biochemical markers of disease activity was compared between pen and syringe users. RESULTS Of 218 patients, 64% used pen, with a median faecal calprotectin 110 μg/g and serum C-reactive protein 4 mg/L. In comparison to pen, syringe users had higher albumin [39 vs 42 g/L; p = 0.016], lower Harvey-Bradshaw Index [2 vs 1; p = 0.017], and higher rates of concomitant immunomodulation [54% vs 71%; p = 0.014]. Drug levels were equivalent between pen and syringe users [median 5.3 vs 5.2 μg/ml; p = 0.584], even after controlling for disease activity and immunomodulation. Syringe users at Alfred Health had higher drug levels than pen [6.1 vs 4.5 μg/ml; p = 0.039]; a greater proportion achieved therapeutic levels [75% vs 44%; p = 0.045]. A higher proportion of pen users from Saint-Étienne had therapeutic levels [79% vs 42%; p = 0.027], yet no significant difference in drug levels [7.9 vs 4.5 μg/ml; p = 0.119]. CONCLUSIONS Delivery device does not appear to significantly affect adalimumab drug levels. Given differences between study sites, studies evaluating administration education and technique are warranted.

Abstract
Hand hygiene is the most effective strategy to prevent infectious diseases. This study investigated and compared the hand hygiene practices of adults with diabetes and an age- and gender-matched comparison group. Adults with diabetes (n = 22,920) who participated in the 2015 Korea Community Health Survey and an appropriate comparison group (n = 22,920) were selected. Descriptive analyses, chi-square tests, and multiple logistic regression analyses were used. Greater than 98% of participants with diabetes recognized that hand hygiene helps prevent infectious diseases. Among participants with diabetes, 84.3%, 82.4%, 72.5%, and 64.1% washed their hands frequently before eating, after using the restroom, after returning from the outdoors, and with soap or hand sanitizer, respectively, but these values were significantly lower than those of the comparison group. After performing multiple regression analyses, treatments for diabetes, being educated about diabetes management and handwashing, and awareness of hemoglobin A1c levels were significantly associated with hand hygiene practices in participants with diabetes. Almost all people with diabetes were aware of the efficacy of hand hygiene, but handwashing rates were significantly lower in people with diabetes than in the comparison group. Considering treatments for diabetes, educational campaigns regarding handwashing, and increasing awareness of handwashing efficacy will help improve hand hygiene in people with diabetes.

Abstract
AIM This study was conducted to evaluate the insulin pen application knowledge and skills of patients with diabetes. METHODS In our descriptive study, 200 patients with diabetes were asked to present the insulin pen injection technique on a mannequin and the steps of the pen injection implementation were noted on the data collection form as correct/incorrect by researchers. RESULTS More than 3 out of 4 (79.5%) of the participants were using the insulin pen or the cartridge after the expiry date, 70.5% were not rotating the injection site, and 63.0% were massaging the skin after injection. Injection sites complications were significantly more in those who were using the insulin pen or the cartridge after the expiry date, those who don't know the proper length of the needle and the possible body injection sites, those who don't rotate the injection sites, those who massage after injection, and those who don't use a new needle at each injection (p<0.05). CONCLUSION This study put into light some failures in the knowledge and skills of patients with diabetes regarding insulin pen use. Nurses should provide patients with diabetes an effective and repetitive training concerning insulin pen use.

Abstract
BACKGROUND Ease of injection is important to patients. An autoinjector was developed to deliver exenatide, a glucagon-like peptide-1 receptor agonist for type 2 diabetes mellitus. For autoinjection, 0.06-mm exenatide-containing microspheres are suspended in medium-chain triglycerides. Herein, we report design verification and usability testing of the autoinjector for exenatide once-weekly suspension (QWS) delivery. METHODS Exenatide QWS in a single-chamber cartridge is self-injected subcutaneously with three main steps: mix, unlock, and inject. Design verification testing used validated testing methodology. A summative validation study with simulated-use scenarios evaluated unassisted performance on critical tasks (ease of use and the injection process). RESULTS The autoinjector met specified design requirements for dose accuracy and torque/force. Of 104 participants enrolled (73 lay users, 16 health care professionals, and 15 pharmacists), 90 independently referred to instructions for use during testing. Users successfully achieved critical tasks on first attempt 87-100% of the time. Approximately 78% of participants successfully completed the full injection scenario, including 72% of lay users reporting visual or dexterity impairments. Initial use errors on critical tasks included not mixing well (n = 12), not removing needle cap (n = 8), and not holding needle to the skin for complete injection (n = 5). Untrained injection-naïve and trained injection-experienced lay users made the fewest errors (7% and 3%, respectively). Trained and untrained participants took 2:33 and 5:03 minutes, respectively, to complete a weekly injection. CONCLUSIONS Users with a range of injection experience can rapidly learn to administer exenatide QWS autoinjector correctly, thus minimizing patient effort to manage their diabetes with injectable therapy.

Abstract
BACKGROUND Correct insulin injection practice is essential for better diabetic control. The aim of this study is to investigate the level of competency of prefilled insulin pen usage (injection technique and storage) among diabetes patients in Saudi Arabia. METHODS A cross-sectional survey between March 2017 to July 2017 of randomly selected patients with diabetes attending Diabetes Treatment Center, Prince Sultan Military Medical City, Saudi Arabia, who are actively using a prefilled insulin pen, were interviewed to complete a pre-structured questionnaire to assess the competency of using the insulin pen. The contents of the questionnaire addressed the 6 competency components according to manufacturer recommendation (priming, count time, storage, using new needles, a store with no needles, and discard date), background, clinical and metabolic data. Results of the questionnaire were analyzed to identify common pitfalls and were also contrasted with background clinical and metabolic data. RESULTS 165 patients with diabetes (aged 14-70yrs) were interviewed for the study and all questioners completed properly. Only 14 (8.5%) patients were following all of the six competency components. Count time 52 (31.6%) was the least followed competency component of the six, whereas discard date and storage of insulin pen were the most followed with 165 (100%) and 159 (96.4%), consecutively. Education was the only significant variable related to the following more than 3 of the competency components, and logistic regression showed the college or higher educated patients to be three times more likely follow more than 3 of the competency components. CONCLUSION The study concluded that majority of patients are either ignoring or unaware of the major components of correct use of prefilled insulin in Saudi Arabia.

Abstract
INTRODUCTION The 2015 Insulin Injection Technique Questionnaire survey involving 13,289 patients included 898 (6.8%) patients in the pediatric age range (≤ 18 years). METHODS The younger patients included in the questionnaire survey were grouped according to age: Group 1 (G1), 0-6 years, n = 85; Group 2(G2), 7-13, n = 423; Group 3 (G3), 14-18, n = 390. The injection technique was evaluated by means of a questionnaire and nurse assessment. RESULTS Nurses found lipohypertrophy at injection sites in 41.3, 45.2, and 47.3% of patients in G1, G2, and G3, respectively. Unexpected hypoglycemia was common, ranging from 23.8 to 48.1% of patients, and glucose variability was even more common (61.0% in G1, 45.9% in G2, and 52.5% in G3); both conditions were associated with lipohypertrophy. While increasing numbers of patients were using the recommended 4-mm needles, large percentages still used longer ones (33.3% in G1, 45.9% in G2, and 61.5% in G3). The reuse of needles was also common, ranging from 21.1 to 32.5% in the three age groups. Excessive reuse, defined as using a single needle more than five times, was reported by 9.4-21.8% of patients in the three age group. The percentages of patients who had not received any injection training in the last 12 months ranged from 21.2 to 26.8% in the three groups. CONCLUSION Implications of our study are as follows: (1) pediatric patients should use 4-mm pen needles or 6-mm syringes (inserted at a 45° angle); (2) patients aged ≤ 6 years should always inject into a raised skin fold regardless of which device is used; (3) all patients should rotate sites and use needles only once to avoid lipohypertrophy.

Abstract
AIMS To define standard criteria for the detection of lipohypertrophy using ultrasonography and to determine the accuracy of this method. METHOD Individuals using insulin therapy for ≥2 years with unknown lipohypertrophy status were enrolled at a diabetes education centre. A team of diabetes educator nurses performed a clinical examination for evidence of lipohypertrophy and a separate team of ultrasonographers examined participants in a blinded fashion. RESULTS The echo signature for lipohypertrophy consisted of location in the subcutaneous layer and lesions that were 1) well circumscribed either by hyperechoic foci with defined borders or a nodular shape with a hypoechoic halo, 2) heterogeneous in echotexture compared with surrounding tissue, 3) associated with distortion of surrounding connective tissue with 4) absence of vascularity and 5) absence of capsule. Ultrasonography identified individuals with lipohypertrophy significantly more frequently than inspection or palpation (P<0.0001). Inter-observer agreement was moderate (κ=0.50) and limited by the presence of subclinical lesions in 73% of the participants. CONCLUSIONS The ultrasound detection of lipohypertrophy is consistent with clinical examination and is reproducible using a defined echo signature. (ClinicalTrials.gov registration no: NCT02348099).

Abstract
INTRODUCTION Lipohypertrophy (LH) is a common complication occurring in diabetes individuals. The most common methods used include palpation, visual examination and/or ultrasound (US). To date, there is limited information on the detection sensitivity among the different techniques used to identify LH. This systematic review aimed to identify studies that examined insulin-related LH using US detection to identify the prevalence, characteristics and morphology of LH, and to compare US and clinical palpation methods for detecting LH. METHODS Three electronic databases were systematically searched for studies detecting LH using US in insulin users. Articles were screened for eligibility and included studies were appraised using quality assessment tools. The quality of the evidence was evaluated using Grading of Recommendations Assessment, Development and Evaluation, and the extracted data was synthesised narratively. RESULTS Sixteen articles were included in the review providing data on 1722 patients. The prevalence of LH prevalence varied from 14.5% to 88% (median 56.6%). Identified risk factors for the development of included insulin injection behaviour such as a lack of injection site rotation and social factors such as low education level. Four studies compared LH detection by US to palpation, providing inconsistent results. One study showed that palpation detected 64% more LH, whilst two studies demonstrated that US identified 50% more sites and extended areas of LH (additional ~ 5 cm2). Another study provided comparable estimates between palpation and US in clinicians trained to detect LH (97%). CONCLUSION The evidence highlights a lack of congruence in results pertaining to the detection sensitivity of US and palpation for LH sites. More research with robust study design is needed to verify whether clinically palpation is sufficient to detect LH, or whether US would increase the precision of LH assessment to help address this common clinically significant problem.

Abstract
Recently, the multi-needle drug injection has been adopted to overcome the shortcomes of conventional single-needle injection, enhancing the efficiency of drug delivery. However, the effect of needle array on the efficacy of drug delivery has not been fully elucidated. In this study, the interactions of drug analogous solution injected from a pair of needles were analyzed to examine the design criteria of effective multi-needle devices for drug delivery. Temporal and spatial variations of relative contents of the solution in the tissues were compared according to the distance between two adjacent needles (DN). As the DN increases from 5 to 20 D, where D is the needle diameter, the solution from each needle encounters 3.5 times faster, and 4.22 times more solution was accumulated. At the same time, the effective spreading area was continuously increased from 54.2 to 177.8 mm2 and RCS gradient decreases from 0.087 to 0.037, due to the overlapping effect of the spreading solution from neighboring needles. Finally, based on the experimental results, an optimal design criterion of needle array for effective drug delivery was proposed. The present results would be helpful in the design of multi-needle injection devices and eventually offer advantage to patients with effective drug delivery.

Abstract
BACKGROUND Lipodystrophy is one of the clinical complications of insulin injection that affects insulin absorption and leads to poor glycemic control. OBJECTIVE To assess insulin-induced lipodystrophy and glycemic control. METHODS A cross sectional study was done on 176 diabetic children and adolescents who inject insulin for a minimum of one year. First, anthropometric and clinical characteristics of the patients were recorded in questionnaire, and then observation and palpation techniques were used in assessing lipodystrophy. RESULT Out of the total 176 participants, 103 (58.5%) had insulin-induced lipodystrophy, of them 100 (97.1%) had lipohypertrophy and 3 (2.9%) had lipoatrophy. Being younger, failure to rotate the injection site every week and multiple reuse of insulin syringe had significant influence in development of insulin-induced lipohypertrophy. Lipohypertrophy in turn was associated with the use of higher dose of insulin and nonoptimal glycemic control. CONCLUSION Findings of this study revealed that in spite of using recombinant human insulin, the magnitude of the lipohypertrophy still remained high. Therefore, a routine workup of insulin-injecting patients for such complication is necessary, especially in the individuals who have a nonoptimal glycemic control.

Abstract
Management of diabetes for residents in long-term care settings is particularly challenging, due to the wide range of physical and mental limitations that bear on efficacy of their medications, as well as practical issues associated with the optimal administration of these medications. Foremost among the practical issues for residents requiring insulin injections, is the need to ensure that it is consistently delivered to the circulation at the target rate and dosage, thereby avoiding life-threatening episodes of hypoglycemia. Recent evidence from a multinational survey has elucidated principles of insulin injection technique, including optimal needle length and site rotation that can greatly improve consistency in delivering insulin to the subcutaneous compartment, while reducing pain, improving patient compliance, and limiting the total daily dosage. The present review consolidates these findings and highlights the most critical take-home messages for healthcare professionals working in this area.

Abstract
Aim To measure skin thickness (ST) and skin + subcutaneous layer thickness (SCT) by ultrasound and estimate the risk of intramuscular injection (IM) with different needle lengths across injection sites according to age group. Method Children recruited between 1 and 18 years with type 1 and 2 diabetes on insulin injections and divided into three age groups: 1–6 years, 7–12 years and 13–18 years. A portable ultrasound was used to measure ST and SCT at four injection sites on the abdomen, arm, thigh and buttock. Results Total 153 children enrolled for the study. The mean (SD) measurement of ST & SCT at four sites on abdomen, arm, thigh & buttocks were as follows; 4.33 mm (±2.22), 5.55 mm (±2.26), 5.83 mm (±3.12), 6.48 mm (±3.47) in 1–6 years old; 7.11 mm (±3.68), 7.79 mm (±4.54), 7.17 mm (±3.62), 8.51 mm (±3.65) in 7–12 years old; 8.94 mm (±4.50), 8.42 mm (±5.00), 8.61 mm (±4.76), 9.76 mm (±4.38) in 13–18 years old. Young children, 1–6 years have the highest risk of IM injection with all needle lengths, i.e. 4, 5, 6, 8 & 12.7 mm, while older children 7–12 & 13–18 years have a lower risk with shorter needles (4, 5 and 6 mm) as compared to longer needles (8 and 12.7 mm). Conclusions Children with diabetes on insulin therapy should be advised on the appropriate needle length accordingly to their age and BMI.

Abstract
OBJECTIVE Subcutaneous insulin absorption is one of the key factors affecting glycemic control in patients with diabetes mellitus under insulin therapy. Insulin-induced subcutaneous lipohypertrophy has been reported to impair insulin regular absorption and hence glycemic control. So far, lipohypertrophy diagnosis has only been clinical. This study aims at evaluating the possible role of ultrasound scan in the assessment of subcutaneous lipohypertrophy in patients affected by type 1 diabetes mellitus. METHODS A pilot observational retrospective study was performed in 20 patients affected by type 1 diabetes mellitus. In these patients the areas with clinical evidence of lipohypertrophy dependent on the insulin injections were characterized by the presence of tissues that at the ultrasound scan resulted similar to fibrotic tissues (hyperechogenic) or to an interstitial edema or to fat tissues (hypoechogenic). It was utilized a multi frequency linear probe (6-18 MHz). The patients were advised to avoid insulin injections on the areas with lipohypertrophy scanned by the ultrasound and the HbA1c changes were evaluated 3 months later. RESULTS The lipohypertrophic areas presented at least three different aspects upon ultrasound assessment: the iso-hyperechogenic one, with a predominant fibrotic component; the isoechogenic one, with "large tangles" fibrotic elements and the iso-hypoechogenic aspect with no fibrotic elements. When patients were advised to avoid insulin injections on areas with lipohypertrophy defined by ultrasound scan, 3 months after the first evaluation HbA1c had significantly improved (basal HbA1c 7.87 ± 0.56 versus 7.67 ± 0.52 3 months later, p = 0.029). No significant improvements of the HbA1c were found in the control matched group in which lipohypertrophy was only clinically valued through inspection and palpation. CONCLUSIONS Ultrasound scan can help identify and characterize the lipohypertrophic areas and this might be useful to improve glycemic control.

Abstract
La lipodistrofia (lipohipertrofia, lipoatrofia) es una complicación dada por la técnica inadecuada de inyección subcutánea de insulina. Se presenta el caso de una paciente de 46 años con diabetes mellitus tipo 2 descontrolada, en tratamiento con insulina glargina 45UI/día, sin control glucométrico y con múltiples ajustes y hospitalizaciones. Al ingreso, el automonitoreo muestra glucometrías basales y posprandiales fuera de metas, glucemia basal de 299 mg/dL y HbA1c de 11%. Al interrogatorio, se evidencian fallas en la técnica de aplicación de insulina, en particular falta de rotación del sitio de aplicación. En el examen físico se encuentra lipohipertrofia dada por panículo adiposo infraumbilical prominente bilateral e induración del tejido celular subcutáneo; en ecografía se visualiza infiltración grasa de rectos anteriores. Se da instrucción a la paciente sobre la correcta técnica de aplicación de insulina con rotación diaria del sitio de aplicación, descanso de zonas con lipohipertrofia y guía para automonitoreo.El automonitoreo en los 10 primeros días mostró mejoría de glucometrías basales hasta 116 mg/dL y valor limítrofe de 75 mg/dL, comparados con promedio de glucometría basal previa de 242 mg/dL con la misma insulina y dosis. Se hizo seguimiento estrecho para definir dosis requerida de insulina y vigilar posible hipoglucemia, con mejoría en la HbA1c de 9.2% y 8.8% a los 4 y 11 meses, respectivamente.

Abstract
BACKGROUND Jet injection has been shown to accelerate the absorption and action of rapid-acting insulin. In this study, we compared the variability of absorption characteristics between jet injection and conventional administration of the rapid-acting insulin analogue aspart. METHODS A total of 30 healthy volunteers were enrolled in this randomized controlled blinded parallel study. On two test days, they received insulin aspart (0.2 units/kg body weight), either by jet injection or conventional pen, followed by a 6-hour euglycemic glucose clamp. Plasma glucose and insulin levels and glucose infusion rates were measured every 5 to 10 minutes to calculate the variability in pharmacological endpoints. RESULTS Jet injection advanced the times until maximal insulin concentration (T-INSmax) and glucose infusion rate (T-GIRmax) by ~40% (both P < .01). The difference between the two test days for these endpoints did not differ between jet injection and conventional administration (T-INSmax: 7.3 ± 1.9 vs 22.3 ± 6.3 min, P = .074; T-GIRmax: 24.0 ± 3.5 vs 27.3 ± 6.6 min, P = .66). The corresponding intraindividual coefficients of variation for injection by jet or conventional pen were 15.3 ± 3.3 and 22.0 ± 4.6% ( P = .25, Pvariance = .044) for T-INSmax and 34.5 ± 5.1 and 21.2 ± 4.6% for T-GIRmax ( P = .064, Pvariance = .62). The variance in maximal insulin concentration was significantly less after conventional administration ( P = .039). The variance in total glucose-lowering effect and total insulin exposure did not differ ( P = .93 and P = .32) Conclusion: Using a jet injector for insulin administration was associated with slightly altered variability in pharmacokinetic endpoints, but with about similar variability in pharmacodynamic endpoints compared to conventional administration. Variability in these endpoints remains considerable, regardless of the method of insulin administration.

Abstract
Subcutaneous injection of drug solution is widely used for continuous and low dose drug treatment. Although the drug injections have been administered for a long time, challenges in the design of injection devices are still needed to minimize the variability, pain, or skin disorder by repeated drug injections. To avoid these adverse effects, systematic study on the effects of injection conditions should be conducted to improve the predictability of drug effect. Here, the effects of injection conditions on the drug permeation in tissues were investigated using X-ray imaging technique which provides real-time images of drug permeation with high spatial resolution. The shape and concentration distribution of the injected drug solution in the porcine subcutaneous and muscle tissues are visualized. Dynamic movements of the wetting front (WF) and temporal variations of water contents in the two tissues are quantitatively analyzed. Based on the quantitative analysis of the experimental data, the permeability of drug solution through the tissues are estimated according to permeation direction, injection speed, and tissue. The present results would be helpful for improving the performance of drug injection devices and for predicting the drug efficacy in tissues using biomedical simulation.

Abstract
OBJECTIVE The purpose of this study is to explore current practice regarding insulin administration by nurses in a Greek public hospital. DESIGN AND METHODS A mixed-methods qualitative data collection design was used with ad hoc nonparticipant observation and post hoc interviews with the staff involved. Insulin management and administration was observed and compared to international guidelines. A sample of 20 nurses from two medical wards was assessed on 100 occasions of insulin administration, and 8 nurses were subsequently interviewed. RESULTS Inter-rater agreement was found to be satisfactory (average κ 0.840). In 61% of all instances, nurses washed their hands before administering insulin, and, in 70%, they donned gloves before injections. In 64.5% of all instances, the nurses did not clean the insulin bottle before inserting the needle, and in 42.7% of instances, they did not check for air bubbles in the syringe. In 89.1% of instances, nurses did not check the injection site for appropriateness or other possible complications. However, in 90.9%, they cleaned the skin at the injection site with an alcohol swab. In 70.9% of all instances, the needle was placed vertically to the skin but without a skinfold. In 89.1% of instances, post-injection care was rated as poor. CONCLUSION Overall, compliance with international guidelines regarding insulin administration techniques, as observed in these sample wards, is not satisfactory. Nurses in this Greek hospital tend to administer subcutaneous injections in ways not reflected in current research findings, practice guidelines, or evidence-based care recommendations. Evidently, Greek nurses in this sample require updating on current evidence-based practice, clinical guidelines, and protocols of care regarding routine insulin administration.

Effect of re-coaching on self-injection of insulin in older diabetic patients - Impact of cognitive impairment. Diabetes Res Clin Pract 2017; 130:34-42. [PMID: 28554141 DOI: 10.1016/j.diabres.2017.05.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2016] [Revised: 05/02/2017] [Accepted: 05/08/2017] [Indexed: 12/30/2022]
Abstract
AIMS We investigated the effect of re-coaching on self-injection of insulin and impact of cognitive function in 100 older diabetic patients. METHODS We examined patients on a variety of skills and knowledge regarding self-injection of insulin and evaluated the effect of re-coaching the patients after 3months and 4years. We also investigated the influence of cognitive impairment (CI) on coaching. RESULTS Skills scores for self-injection of insulin and HbA1c improved significantly 3months after re-coaching. In 51 patients followed-up for 4years, skills scores were maintained during the 4years, while knowledge scores improved after 3months but then returned to the baseline level. In the group of patients with CI as determined by the Mini-Mental Status Examination, skills scores were similar to those in the group without CI, while knowledge scores were significantly lower as compared with those in the group without CI at any time point. Skills scores were maintained during the 4years regardless of CI. CONCLUSION The present study showed that re-coaching in skills for self-injection of insulin was effective in improving and maintaining insulin treatment in older diabetic patients, even if patients had CI.

Abstract
The incretin system has become an important target in the treatment of type 2 diabetes in recent years, and glucagon-like peptide 1 (GLP-1) is of particular interest for its glucose-lowering effects. The physiological response to oral ingestion of nutrients, involving the incretin system, is reduced in some patients with type 2 diabetes but may be augmented by administration of GLP-1 receptor agonists. The GLP-1 receptor agonists currently approved in the United States for the treatment of type 2 diabetes include exenatide (administered twice daily), liraglutide and lixisenatide (administered once daily), and the once-weekly agents exenatide extended-release, albiglutide, and dulaglutide. These agents have been shown to reduce A1C (by ∼0.8-1.6%), body weight (by ∼1-3 kg), blood pressure, and lipids. GLP-1 receptor agonists are associated with a low risk of hypoglycemia, and the most common adverse effects are gastrointestinal. Proper patient selection and education can assist in achieving positive treatment outcomes.
