Glycemic variability assessed by continuous glucose monitoring system in insulin-treated diabetic patients on hemodialysis

Glycemic variability assessed by continuous glucose monitoring system in insulin-treated diabetic patients on hemodialysis

Continuous Glucose Monitor Metrics Are Associated with Emergency Department Visits and Hospitalizations for Hypoglycemia and Hyperglycemia, but Have Low Predictive Value.

Objective: Determine whether continuous glucose monitor (CGM) metrics can provide actionable advance warning of an emergency department (ED) visit or hospitalization for hypoglycemic or hyperglycemic (dysglycemic) events. Research Design and Methods: Two nested case-control studies were conducted among insulin-treated diabetes patients at Kaiser Permanente, who shared their CGM data with their providers. Cases included dysglycemic events identified from ED and hospital records (2016-2021). Controls were selected using incidence density sampling. Multiple CGM metrics were calculated among patients using CGM >70% of the time, using CGM data from two lookback periods (0-7 and 8-14 days) before each event. Generalized estimating equations were specified to estimate odds ratios and C-statistics. Results: Among 3626 CGM users, 108 patients had 154 hypoglycemic events and 165 patients had 335 hyperglycemic events. Approximately 25% of patients had no CGM data during either lookback; these patients had >2 × the odds of a hypoglycemic event and 3-4 × the odds of a hyperglycemic event. While several metrics were strongly associated with a dysglycemic event, none had good discrimination. Conclusion: Several CGM metrics were strongly associated with risk of dysglycemic events, and these can be used to identify higher risk patients. Also, patients who are not using their CGM device may be at elevated risk of adverse outcomes. However, no CGM metric or absence of CGM data had adequate discrimination to reliably provide actionable advance warning of an event and thus justify a rapid intervention.

Hypoglycemia unawareness among insulin-treated diabetic patients in Madinah, Saudi Arabia: prevalence and risk factors.

Hypoglycemia unawareness (HU) is associated with significant risks. Screening for impaired awareness of hypoglycemia in patients with diabetes is important to minimize those risks. There are limited data on the prevalence of HU in patients with diabetes in Saudi Arabia (KSA). In the current study, we investigated the frequency of HU and its risk factors among insulin treated diabetic patients in Madinah, KSA. A cross-sectional study was conducted in a diabetes center and four primary healthcare centers at Madinha, KSA. Patients ≥14 years old with type 1 or type 2 diabetes treated with insulin for more than a year were included. HU was assessed by Clarke's and modified Pedersen-Bjergaard's scores. The risk factors for HU were determined. Of the 413 included patients, 60.3% were women, and 60.8% were on insulin alone. One-third of the participants had T1DM, while 68.5% had T2DM, with median ages of 25 and 56 years, diabetes durations of 10 and 15 years, and durations of insulin use of 10 and 5 years, respectively. The prevalence of HU was 25.2% by Clarke's survey. The risk factors for HU were poor knowledge of the patient's latest HbA1c, type of insulin, and dose of insulin. Poor medical follow-up, previous stroke, and ischemic heart disease were the other risk factors for HU. When the modified Pedersen-Bjergaard method was used, the prevalence of HU was 48.9%. Despite the advances in diabetes management, HU continues to be prevalent among diabetic patients on insulin, and poor diabetes knowledge is a major risk factor. Diabetes education on self-management is of utmost importance to reduce hypoglycemia and HU.

Accuracy of Continuous Glucose Monitoring in an Insulin-Treated Population Requiring Haemodialysis.

Continuous glucose monitoring (CGM) is revolutionizing diabetes care by giving both patients and the healthcare professionals unprecedented insights into glucose variability and patterns. It is established in National Institute for Health and Care Excellence (NICE) guidance as a standard of care for type 1 diabetes and diabetes in pregnancy under certain conditions. Diabetes mellitus (DM) is recognized as an important risk factor for chronic kidney disease (CKD). Around a third of patients receiving in-center haemodialysis as renal replacement therapy (RRT) have diabetes, either as a direct cause of renal failure or as an additional co-morbidity. Evidence of poor compliance with the current standard of care (self-monitoring of blood glucose [SMBG]) and overall greater morbidity and mortality, suggests this patient population as an ideal target group for CGM. However, there exists no strong published evidence showing the validity of CGM devices in insulin-treated diabetes patients requiring haemodialysis. We applied a Freestyle Libre Pro sensor to 69 insulin-treated diabetes haemodialysis (HD) patients on a dialysis day. Interstitial glucose levels were obtained, and time matched within 7 minutes to capillary blood glucose testing and any plasma blood glucose levels sent. Data cleansing techniques were applied to account for rapidly correcting hypoglycaemia and poor SMBG technique. Clarke-error grid analysis showed 97.9% of glucose values in an acceptable range of agreement (97.3% on dialysis days and 99.1% on non-dialysis days). We conclude that the Freestyle Libre sensor is accurate in measuring glucose levels when compared to glucose as measured by capillary SMBG testing and laboratory obtained serum glucose in patients on HD.

Incidence and costs of hypoglycemia in insulin-treated diabetes in Switzerland: A health-economic analysis

AimsWe assess the incidence and economic burden of severe and non-severe hypoglycemia in insulin-treated diabetes type 1 and 2 patients in Switzerland. MethodsWe developed a health economic model to assess the incidence of hypoglycemia, the subsequent medical costs, and the production losses in insulin-treated diabetes patients. The model distinguishes between severity of hypoglycemia, type of diabetes, and type of medical care. We used survey data, health statistics, and health care utilization data extracted from primary studies. ResultsThe number of hypoglycemic events in 2017 was estimated at 1.3 million in type 1 diabetes patients and at 0.7 million in insulin-treated type 2 diabetes patients. The subsequent medical costs amount to 38 million Swiss Francs (CHF), 61 % of which occur in type 2 diabetes. Outpatient visits dominate costs in both types of diabetes. Total production losses due to hypoglycemia amount to CHF 11 million. Almost 80 % of medical costs and 39 % of production losses are due to non-severe hypoglycemia. ConclusionsHypoglycemia leads to substantial socio-economic burden in Switzerland. Greater attention to non-severe hypoglycemic events and to severe hypoglycemia in type 2 diabetes could have a major impact on reducing this burden.

Factitious hypoglycemia in insulin-treated diabetic patients

Factitious hypoglycemia is a factitious disorder according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), referring to intentionally covertly induced hypoglycemia, with potentially severe consequences. Knowledge of factitious hypoglycemia relies on case reports, and evidence-based information and guidelines are lacking. Diagnosing factitious hypoglycemia in insulin-treated diabetic persons is therefore challenging and often requires a long and costly process. Moreover, the typical metrics proposed to differentiate insulin-induced factitious hypoglycemia from insulinoma (i.e., high insulin and low C-peptide versus high insulin and high C-peptide, respectively) are not always applicable, depending on whether the insulin quantification method can detect the insulin analog. When factitious hypoglycemia is suspected, an emerging trend from recent publications advocates a combination of two insulin quantification methods with different cross-reactivity for insulin analogs, early on in the diagnostic process.

Lipohypertrophy prevalence and its associated risk factors in insulin-treated patients with type 2 diabetes in North Borneo, Malaysia.

Insulin-treated diabetes patients are at high risk of developing lipohypertrophy, which can negatively impact treatment outcomes. Early detection of lipohypertrophy is crucial to preventing blood glucose fluctuation. Unfortunately, this clinical issue is often overlooked by nurses, causing the development of vascular complications, which leads to an increase in the morbidity and mortality of the type 2 diabetes mellitus population. This study was conducted to identify lipohypertrophy prevalence and to establish the association between the presence of lipohypertrophy and its associated risk factors, including years on injection, total injection in a day, total insulin unit per day, often change needle, insulin injection site and move to a different area. This cross-sectional study included 128 patients with type 2 diabetes mellitus who received insulin therapy in an outpatient diabetic clinic. Questionnaires on socio-demographic and lipohypertrophy-associated risk factors were distributed among patients, and lipohypertrophy-assessment was done using a checklist. Descriptive statistics and Pearson Chi-square were used for statistical analysis. The prevalence of lipohypertrophy was 51.6% (95% CI: 42.6, 60.5). Swelling on fatty tissue (46.1%) exhibited the highest percentage of lipohypertrophy features during the assessment. Pearson Chi-Square revealed a significant relationship between the presence of LH and BMI categories (χ2 = 10.059, df = 3, p = 0.018), duration of injection (χ2 = 15.001, df = 3, p = 0.002), frequency of needle replacement (χ2 = 9.525, df = 3, p = 0.023) and rotation of injection site (χ2 = 5.914, df = 1, p = 0.015). The high prevalence of lipohypertrophy indicates a need for a prevention strategy. Thus, nurses should play an important role in educating patients regarding the proper administration of insulin injections and performing a routine lipohypertrophy assessment and health education on the correct method of insulin injection.

Precipitating Factors of Hypoglycemia in Diabetic Patients Undergoing Treatment in Taksin Hospital

Background: Hypoglycemia is the most common complication and the most important obstacle to overcome to achieve good glycemic control in diabetic patients. It causes serious consequences, leading to increased morbidity and mortality. Objective: To identify the precipitating factors of hypoglycemia in diabetic patients undergoing treatment in Taksin hospital. Materials and Methods: A case-control study was conducted in 110 diabetic patients admitted due to hypoglycemia and 110 diabetic patients admitted for other reasons at Taksin Hospital, between October 2019 and September 2020. The sociodemographic information, clinical data, and precipitating causes of hypoglycemia were obtained from medical records. Logistic regression analysis was performed to identify the risk factor and reported as odds ratio (OR) with 95% confidence intervals (CI). Results: The multiple logistic regression analysis showed that the precipitating factors related to hypoglycemia among diabetic patients with a significant p-value (p<0.05) were poor self-care knowledge of hypoglycemia prevention (adjusted OR 14.37, 95% CI 5.75 to 35.89), insulin treatment in diabetic patients (adjusted OR 13.78, 95% CI 5.43 to 34.99), and intensive glycemic control HbA1c of less than 6% (adjusted OR 3.64, 95% CI 1.70 to 7.79). Furthermore, the result from the present study showed that individual factors were statistically significant and related to hypoglycemia. The factors included the age more than 60 years, low education level, functionally dependent patients, diabetes duration more than 10 years, hypertension, dyslipidemia, diabetic retinopathy, diabetic nephropathy, diabetic neuropathy, and cognitive impairment. Conclusion: Poor self-care knowledge of hypoglycemia prevention, insulin treatment in diabetic patients, and intensive glycemic control were strong predictors of hypoglycemia in diabetic patients undergoing treatment in Taksin Hospital. Therefore, diabetes self-management education and tailoring diabetic therapy should be provided in diabetic patients to improve treatment and prevention of hospitalization due to hypoglycemia in diabetes.

Prevalence of Lipohypertrophy and its Associations in Insulin-Treated Diabetic Patients.

Lipohypertrophy is a major complications of insulin therapy especially attributed to incorrect insulin technique. The objective was to determine the frequency of lipohypertrophy in diabetic population on insulin and its associations. This cross-sectional study was conducted at the Services Hospital Lahore from July 1st, 2020 to December 31st, 2020. Total of 363 diabetic patients, fulfilling the inclusion criteria were approached. The patients were examined and interviewed through a validated questionnaire. The data was stratified according to the age, gender, duration of diabetes, duration of insulin use, frequency of LH and duration since last instructions reviewed. The chi-square test was applied. Data was analyzed using SPSS 22. Mean age of the study population was 49.71± 13.36 years. Majority were females (57.6%). LH was noted in 22.86% of participants (n=83). There was significant statistical difference noted (P <0.05) between different age groups as 29.7 % of patients in age group above 45 had LH as compared to 19.6% in the below 45 years age group. More females (28.2%) were having LH than the males (15.6%) with P<0.05. Also, significant difference was noted for needle reuse more than 10 times, more than two injections per day and longer duration since last instructions reviewed. No significant difference was noted between different devices for injection as well as for duration of diabetes. LH is strongly associated with hypoglycemia and hyperglycemia with P<0.05. A significant diabetic population on insulin has noted to have LH, and the risk is more with aged population, female gender, more injections per day and multiple time needle reuses. Risk of LH can be reduced by reinforcing education.

The Molecular Mechanism of Insulin Resistant and Glycogen Synthase Kinase 3β In the Progression of Alzheimer's disease In Type 2 Diabetes Mellitus Patients

Type 2 Diabetes mellitus (T2DM) is characterized by high blood sugar caused by a lack of insulin, insulin resistance, or both. It's linked to the onset of secondary problems, which can lead to a variety of co-morbidities. Recent research has found that diabetics are more likely to acquire cognitive impairment or dementia. Diabetes is linked to a number of neurological illnesses, including Alzheimer's disease (AD). Evidence of a relationship between diabetes and AD is growing. Insulin signalling disruption in the brain has been discovered, resulting in increased tau protein phosphorylation (hyperphosphorylation), a hallmark and diagnostic of AD pathology, and the buildup of neurofibrillary tangles (NFT). Insulin malfunction in the brain has been shown to modify glycogen synthase kinase-3β (GSK-3β) activity, resulting in increased β amyloid and tau phosphorylation in diabetics. GSK-3β signalling has been implicated in the physiological and pathological processes of diabetes and AD, respectively. This could explain why diabetic individuals have a higher chance of developing AD as their diabetes progresses and they get older. Interestingly, several in vivo investigations with oral antidiabetic medications and insulin treatment in diabetic patients showed improved cognitive function and lower tau hyperphosphorylation. The relationship between T2DM and AD as it relates to amyloid and tau pathology will be discussed in this article. A better knowledge of the relationship between T2DM and AD could transform how researchers and doctors handle both diseases in the future, potentially leading to new therapies and prevention techniques.

Greater plaque burden and cholesterol content may explain an increased incidence of non-culprit events in diabetic patients: a Lipid-Rich Plaque substudy.

Diabetes mellitus (DM) is associated with increased cardiovascular morbidity and mortality. The multicentre, prospective Lipid-Rich Plaque trial (LRP) examined non-culprit (NC) non-obstructive coronary segments with a combined near-infrared spectroscopy (NIRS)-intravascular ultrasound (IVUS) catheter. This study assessed the differences in NC plaque characteristics and their influence on major adverse cardiac events (MACE) in diabetic and non-diabetic patients. Patients with known DM status were divided into no diabetes, diabetes not treated with insulin (non-ITDM), and insulin-treated diabetes (ITDM). The association between presence and type of DM and NC-MACE was assessed at both the patient and coronary segment levels by Cox proportional regression modelling. Out of 1552 patients enrolled, 1266 who had their diabetes status recorded were followed through 24 months. Female sex, hypertension, chronic kidney disease, peripheral vascular disease, and high body mass index were significantly more frequent in diabetic patients. The ITDM group had more diseased vessels, at least one NC segment with a maxLCBI4 mm ≥400 in 46.2% of patients, and maxLCBI4 mm ≥400 in nearly one out of six Ware segments (15.2%, 125/824 segments). The average maxLCBI4 mm significantly increased from non-diabetic patients (NoDM) to non-insulin-treated diabetic patients (non-ITDM) to insulin-treated diabetic patients (ITDM; 137.7 ± 161.9, 154.8 ± 173.6, 182.9 ± 193.2, P < 0.001, respectively). In patients assigned to follow-up (692 ± 129 days), ITDM doubled the incidence of NC-MACE compared with the absence of diabetes (15.7% vs. 6.9%, P = 0.0008). The presence of maxLCBI4 mm>400 further increased the NC-MACE rate to 21.6% (Kaplan-Meier estimate). Cholesterol-rich NC plaques detected by NIRS-IVUS were significantly more frequent in diabetic patients, especially those who were insulin-treated, and were associated with an increased NC-MACE during follow-up.

Feto-Maternal Outcomes and Treatment Compliance in Metformin Versus Insulin-Treated Gestational Diabetic and Non-Diabetic Patients at the Rehman Medical Institute, Peshawar.

IntroductionGestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance with onset or first recognition during pregnancy. The diagnosis is made on the basis of the oral glucose tolerance test (OGTT) which according to the guidelines of ACOG regards a blood glucose level higher than 190mg/dL after the one-hour test as the criteria for GDM. The first-line agent for GDM is insulin injections; however, it has high costs and also causes its own feto-maternal complications which can include weight gain and polyhydramnios. On the contrary, metformin has fewer complications, is cheaper, and is emerging as a better alternative for the first-line agent for the treatment of diabetes mellitus type 2. GDM had a prevalence of 11.8% in the year 2018 in all trimesters of pregnancy in Pakistan. This study was thus conducted to determine the feto-maternal outcomes of non-GDM and GDM patients on insulin, metformin, and combined treatment respectively admitted to gynecology ward Rehman Medical Institute (RMI) Khyber Pakhtunkhwa, Pakistan in the year 2019.ObjectivesTo determine the feto-maternal outcomes in patients of GDM on metformin treatment and the feto-maternal outcomes in patients of GDM on insulin treatment and to compare the feto-maternal outcomes of mothers with GDM to those without GDM.MethodologyThis is a retrospective study conducted from January to April 2020 on patients of gestational diabetes mellitus undergoing either metformin, insulin, or both therapies admitted to the gynecology ward, Rehman Medical Institute (RMI). After getting ethical approval from the institutional ethical approval board, data were collected for the entire year of 2019 on the basis of proforma with the variables: demographic data, glycemic control (via OGTT), mode of labor, primary open-angle glaucoma (POAG), and feto-maternal outcomes. Data was entered and analyzed via SPSS version 21.0 (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY) and the data were run through various tests including descriptive statistics, cross-tabulations, and chi-square. Results were formulated on the basis of these reports which were then presented in the form of graphs and tables.ResultsOut of 150 mothers who were admitted for delivery at the gynecology ward, 123 (82.0%) women were 30-40 years of age. Non-gestational diabetics patients were 78 (52%) whereas gestational diabetic mothers were 72 (48%); within these GDM-positive mothers 44 (61.1%) were on metformin, 21 (29.1%) were on insulin and seven (9.7%) were on combined treatment. Among modes of delivery, C-section was the most common (113 [76%]), mostly in non-GDM mothers (95 [45.1%]) followed by those on metformin treatment (36 [31.8%]). Considering fetal outcomes there was a significant association between NICU admissions, neonatal jaundice, and breech presentation with insulin-treated mothers (p=0.06, p=0.003, p=0.004, respectively CI=95%). Among maternal outcomes, there was a significant association between pregnancy-induced hypertension (PIH) and insulin-treated patients (p=0.02 CI=95%), premature rupture of membranes (PROM), and metformin-treated patients (p=0.01 CI=95%) whereas eclampsia was significantly associated with mothers not having GDM (p=0.001 CI=95%).ConclusionBased on this preliminary data and considering feto-maternal outcomes, metformin appears to be a safer drug as compared to insulin in the treatment of GDM with more compliance.

Insulin Edema in Type 2 Diabetes Mellitus: A Case Report Study

Edema is a rare complication induced by insulin therapy, which is mostly developed after initiation or intensification of insulin treatment in diabetic patients. Edema can either be localized or generalized. Our patient was a 34-year-old woman with type 2 diabetes. She was under treatment with oral agents medication, but recently insulin therapy was initiated for her due to inability to control her hyperglycemia and development of diabetic ketoacidosis. The patient referred while suffering from bilateral lower extremity edema. During follow-up, her edema resolved spontaneously without any specific treatments. In this patient, the diagnosis of edema was based on ruling out other causes, along with more accurate blood glucose control during diabetic ketoacidosis process and spontaneous recovery. Based on our finding, it can be concluded that insulininduced edema is not a worrisome problem and in most cases, its symptoms resolve without treatment and through restricting the consumption of water and salt.&#x0D;  

Immunotherapy-Related Autoimmune Diabetes Mellitus and Exogenous Insulin Antibody Syndrome in a Patient With Metastatic Oral Squamous Cell Carcinoma

Introduction: Exogenous insulin antibody syndrome (EIAS) is a rare condition characterized by wide glycemic excursions and recurrent hypoglycemia in the presence of high insulin antibody titers. It has been described in diabetic patients treated with exogenous insulin. Programmed death ligand 1 (PD-L1) inhibitors are known to cause autoimmune diabetes mellitus, but PD-L1-related EIAS has not yet been reported to our best knowledge. Case Description: A 63 years old Caucasian man with history of recurrent oral squamous cell cancer presented to emergency room with polyuria, polydipsia, nausea, and vomiting 3 months after initiation of immunotherapy (Durvalumab and cetuximab). He had no prior history of diabetes mellitus or hypoglycemia. He was admitted to hospital for management of diabetic ketoacidosis (Anion gap of 24 mEq/L, venous blood glucose of 805 mg/dL, Venous PH of 7.12, large urine ketone, A1C of 8.9%). After a brief hospital stay, the patient was discharged home on insulin glargine and metformin. His immunotherapy was resumed after hospital discharge. When the patient was seen by Endocrinologist in the clinic, metformin was discontinued and prandial insulin lispro was added. This basal-bolus insulin regimen improved his glycemic control initially. However, without significant changes in his lifestyle or medical condition, he developed worsening postprandial hyperglycemia and recurrent fasting hypoglycemia. Up-titration of his mealtime insulin did not lower postprandial hyperglycemia but possibly worsened fasting hypoglycemia. EIAS was suspected after reviewing his continuous glucose monitoring data. Further work up at this point revealed mildly elevated glutamic acid decarboxylase antibodies (5.9 units/mL, normal range 0.5 - 5.0) and markedly elevated insulin antibody level (77.0 µU/mL, normal range <5). His blood C-peptide was undetectable when his venous blood glucose was 252 mg/dl. In addition, his total insulin level (198 uU/mL) was much higher than his free insulin level (38 uU/mL) following an insulin lispro injection. The patient was diagnosed with EIAS. Switching insulin lispro to insulin aspart while he was on a different immunotherapy medication (Pembrolizumab) immediately reduced his average blood glucose and reduced his total daily insulin dosage by more than 50%. This improvement in glycemic control with insulin aspart only lasted for about 1 week. Unfortunately, the patient’s squamous cancer progressed on immunotherapy. He was referred to hospice care and passed away. Conclusion: Evaluation for EIAS would be reasonable in insulin-treated diabetic patients who develop wide glucose excursions and unexplained fasting hypoglycemia while on immunotherapy.

‘This disease would suit better those who have money’: Insulin-Treated Diabetes Illness Experience in rural Malawi

Understanding the illness experience among rural-based insulin-treated diabetic patients has implications for practice and policy. However, there is a lack of in-depth knowledge about insulin-treated diabetic patients' illness experiences in rural Malawi. We explored the experiences of people living with insulin-treated diabetes in rural Malawi. The study used a qualitative narrative inquiry. Participants were identified at Kamuzu Central Hospital Diabetes Clinic. The hospital is a tertiary level health care facility. We purposively selected 10 participants from rural areas attending the clinic. Data were collected through in-depth interviews in the privacy of the homes of the study participants and analysis was done using Riessman approach of thematic narrative analysis. The following five themes emerged: (1) diabetes perceived as the illness for the rich; (2) 'everything is on a standstill'; (3) dietary challenges of the diabetes illness experience; (4) drug-related challenges associated with the diabetes illness experience and (5) experiencing physical effects of the diabetes illness. Rural-based insulin-treated diabetic patients struggled to live with the illness in the context of low resources. There is a need for multi-factorial approaches at both the community and system levels so as to support people living with diabetes in the rural areas in order to improve their experiences.

Glycopenia - induced sympathoadrenal activation in diabetes mellitus and uncontrolled arterial hypertension: an observational study

BackgroundAim of this study is to investigate a possible association of hypoglycemic episodes and arterial hypertension. We hypothesize that hospitalized insulin-treated diabetes patients with hypertensive crisis have more hypoglycemic episodes than their counterparts without hypertensive crisis on admission.MethodsIn a prospective, observational cohort study, 65 insulin-treated diabetes patients (type 1, type 2, type 3c) were included in Group 1, when a hypertensive crisis was present, as control patients in Group 2 without hypertensive crisis or hypoglycemia, in Group 3, when a symptomatic hypoglycemia was present on admission. All patients were subjected to open-label continuous glucose monitoring, 24-h blood-pressure- and Holter electrocardiogram recordings, and to laboratory tests including plasma catecholamines.Results53 patients, thereof 19 Group-1, 19 Group-2, 15 Group-3 patients, completed this study. Group-1 patients had the highest maximum systolic blood pressure, a higher daily cumulative insulin dose at admission, a higher body-mass index, and a higher plasma norepinephrine than control patients of Group 2. Group-3 patients had more documented hypoglycemic episodes (0.8 ± 0.5 per 24 h) than Group-2 patients (0.2 ± 0.3 per 24 h), however, they were not different to the ones in Group-1 patients (0.4 ± 0.4 per 24 h). Plasma norepinephrine and mean arterial blood pressure were higher Group-1 and Group-3 patients than in control patients of Group 2. At discharge, the daily cumulative insulin dose was reduced in Group-1 (− 18.4 ± 24.9 units) and in Group-3 patients (− 18.6 ± 22.7 units), but remained unchanged in Group-2 control patients (− 2.9 ± 15.6 units).ConclusionsAn association between hypoglycemic events and uncontrolled hypertension was found in this study.

[Diabetic patients, knowledge respectives complications and severity].

Education is at the cornerstone of management of insulin-treated diabetic patient. Previous studies reported that the education of diabetic patients and their entourage was failing, hypothesizing that this lack of education was explained by a lack of knowledge on the disease and its complications and the underestimation of their respective severity. The "Educated Why" suggests that diabetic patients treated with insulin know that hypoglycemia and to a lesser extent diabetes itself are serious or very serious diseases.

Stochastic Latent Residual Approach for Consistency Model Assessment

Hypoglycaemia is a condition when blood sugar levels in body are too low. This condition is usually a side effect of insulin treatment in diabetic patients. Symptoms of hypoglycaemia vary not only between individuals but also within individuals making it difficult for the patients to recognize their hypoglycaemia episodes. Given this condition, and because the symptoms are not exclusive to only hypoglycaemia, it is very important for patients to be able to identify that they are having a hypoglycaemia episode. Consistency models are statistical models that quantify the consistency of individual symptoms reported during hypoglycaemia. Because there are variations of consistency model, it is important to identify which model best fits the data. The aim of this paper is to asses and verify the models. We developed an assessment method based on stochastic latent residuals and performed posterior predictive checking as the model verification. It was found that a grouped symptom consistency model with multiplicative form of symptom propensity and episode intensity threshold fits the data better and has more reliable predictive ability as compared to other models. This model can be used in assisting patients and medical practitioners to quantify patients' reporting symptoms capability, hence promote awareness of their hypoglycaemia episodes so that corrective actions can be quickly taken.

Improved insulin injection technique, treatment satisfaction and glycemic control: Results from a large cohort education study

ObjectiveThe aim of this study was to elucidate injection techniques, treatment satisfaction and glycemic control after education among patients with type 2 diabetes. Methods4513 insulin-treated diabetic patients enrolled in the observational study EGIDA II (Education and GensuPen In Diabetology II) filled out the questionnaire which focused on key insulin injection parameters, pain sensation scale and satisfaction of the treatment form before (visit 1) and after 3 months treatment with insulin injection (visit 2). The education was performed by trained healthcare professionals. To assess the utility and comfort during using new automatic injection system (GensuPen) we separated 2 groups: A – treated with GensuPen and B – treated with other pens. ResultsThe education resulted in increased number of patients who properly remix cloudy insulin; inject insulin into skin; change every time the injection site; use the pen needle only once; prepare a pen for injection and store insulin. We noticed significant decrease in BMI and sensation of pain in both groups. Our study revealed that patients’ satisfaction with the treatment increased with each of the 5 items (type of the treatment, mood, physical activity, vital energy, a sense of control over the disease) using a 5-point scale, with greater increase in group A. The utility and comfort (weight, thickness, easiness in remove pen cap, cleaning, twisting, keeping in hand the pen, dial the dose, readable signaling of injected dose) during using the GensuPen significantly increased in group A. Finally the mean glucose level in self-control diary was significantly lower after 3 months of the treatment in both groups, however the difference between visit 1 and 2 was greater in group A. ConclusionThe study showed that proper selection of pen and professional education can result in the improvement of insulin injection technique, higher patients’ satisfaction and better glycemic control.

Impact of Insulin-Treated and Noninsulin-Treated Diabetes Mellitus in All-Comer Patients Undergoing Percutaneous Coronary Interventions With Polymer-Free Biolimus-Eluting Stent (from the RUDI-FREE Registry)

Patients with diabetes mellitus (DM) have worse outcomes after percutaneous coronary intervention (PCI). Recent evidences suggest a differential impact of insulin-treated and noninsulin-treated DM on prognosis. We evaluated the clinical outcome of diabetic patients after PCI with polymer-free biolimus-eluting stent from the RUDI-FREE Registry, investigating a possible different prognostic impact of insulin-treated and noninsulin-treated DM. A total of 1,104 consecutive patients who underwent PCI with polymer-free biolimus-eluting stent, enrolled in the RUDI-FREE observational, multicenter, single-arm registry, were stratified by diabetic status; diabetic population was further divided on the basis of insulin treatment. Primary end points of the study were target lesion failure (TLF; composite of cardiac death, target vessel myocardial infarction, target lesion revascularization) and major adverse cardiac and cerebrovascular events (composite of cardiac death, stroke, and myocardial infarction). Multiple ischemic adverse events were also single-handedly considered as secondary end points. At 1 year, TLF was significantly higher in the diabetic cohort, as compared with nondiabetic patients (6.0% vs 3.1%, p 0.022). None of the end points resulted significantly different between nondiabetics and noninsulin-treated diabetic patients. Divergently, compared with nondiabetic, insulin-treated diabetic patients faced significant higher rates of TLF (10.8% vs 3.1%, p 0.003), major adverse cardiac and cerebrovascular events (10.8% vs 3.4%, p 0.004), and of most of the analyzed adverse events. In conclusion, patients with DM had a higher risk of TLF compared with nondiabetics; nonetheless, the worse outcome of the diabetic population seems to be driven by the insulin-treated diabetic subpopulation. This finding suggests a different risk profile of insulin-treated and noninsulin-treated diabetic patients in the modern era of PCI.
