Quality of life and type 1 diabetes: a study assessing patients' perceptions and self-management needs

The psychosocial outcomes of advanced hybrid closed-loop system in children and adolescents with type 1 diabetes

The study was carried out to determine the psychosocial outcomes of advanced hybrid closed-loop (AHCL) systems in children and adolescents with type 1 diabetes (T1D). Single-center and cohort study with a duration 6 months consisted of 60 children and adolescents with T1D. Standard clinical procedures, including both glycemic indicators, e.g., sensor-measured time within the 70-180 mg/dL range and glycated hemoglobin (HbA1c) levels, and psychosocial metrics were used for data collection. The psychosocial metrics included the Pediatric Quality of Life Inventory (PedsQL) 3.0 Diabetes Module for both children (8-12 years) and parents; the Quality of Life for Youth scale for adolescents (13-18 years); the Strengths and Difficulties Questionnaire (SDQ); the Hypoglycemia Fear Survey for Children (HFS-C); the Revised Child Anxiety and Depression Scale (R-CADS); and AHCLS-specific DTSEQ satisfaction and expectation survey. These metrics were evaluated at the baseline and after 6 months of AHCL use. Of the 60 children and adolescents with T1D for whom the AHCL system was utilized, 41 of them, 23 female and 18 male, completed the surveys. The mean age of the 41 children and adolescents was 12.5 ± 3.2 (min. 6.7, max. 18) years. The time spent within the target glycemic range, i.e., time-in-range (TIR), improved from 76.9 ± 9% at the baseline to 80.4 ± 5% after 6 months of AHCL system use (p = 0.03). Additionally, HbA1c levels reduced from 7.1% ± 0.7% at the baseline to 6.8% ± 0.8% after 6 months of AHCL system use (p = 0.03). The most notable decline in HbA1c was observed in participants with higher baseline HbA1c levels. All patients' HFS-C and AHCL system-specific DTSEQ satisfaction and expectation survey scores were within the normal range at the baseline and remained unchanged during the follow-up period. No significant difference was found in the R-CADS scores of children and adolescents between baseline and after 6 months of AHCL system use. However, there was a significant decrease in the R-CADS scores of the parents. Patients' PedsQL scores were high both at the baseline and after 6 months. The SDQ scores were high at baseline, and there was no significant improvement at the end of 6 months.  Conclusion: This is the first study to investigate in detail the psychosocial outcomes of AHCL system use in T1D patients and their parents. Although state-of-the-art technologies such as AHCL provide patients with more flexibility in their daily lives and information about glucose fluctuations, the AHCL resulted in a TIR above the recommended target range without a change in QOL, HFS-C, SDQ, and R-CADS scores. The scores obtained from the R-CADS conducted by the parents of the children indicated that the use of pumps caused a psychological improvement in the long term, with a significant decrease in the R-CADS scores of the children and adolescents with T1D. What is Known: • Previous studies focused on clinical outcomes of AHCL systems in pediatric T1D patients, showing glycemic control improvements. • Limited attention given to psychosocial outcomes of AHCL systems in children and adolescents with T1D. • Crucial psychosocial factors like quality of life, emotional well-being, and fear of hypoglycemia underexplored in AHCL system context. What is New: • First study to comprehensively examine psychosocial outcomes of AHCL systems in pediatric T1D patients. • Study's robust methodology sets new standard for diabetes technology research and its impact on qualiy of life.

Association between glycemic control and patient-reported outcomes in adults with type 1 diabetes in Japan: the SAGE study subanalysis

Aims/introduction

Psychosocial aspects and the quality of life (QOL) of individuals with diabetes are important for achieving glycemic control and treatment goals. Here, we describe patient-reported outcomes (PROs) of Japanese adults with type 1 diabetes (T1D) and evaluate the association thereof with glycemic control.

Materials and methods

This subanalysis of a subgroup of 528 Japanese participants in the SAGE study of adults with T1D used data on glycosylated hemoglobin (HbA1c) and PRO scores [Hypoglycemia Fear Survey-II (HFS-II), Problem Areas In Diabetes (PAID), Insulin Treatment Satisfaction Questionnaire (ITSQ), and Audit of Diabetes-Dependent QOL (ADDQoL)] and summarized the score by the predefined age groups (26-44-years: n = 208, 45-64-years: n = 217, and ≥ 65-years: n = 103). The association between PROs, achieving HbA1c < 7.0%, and individualized targets was explored using multivariate logistic regression analysis.

Results

The HFS-II and PAID scores were lower, and the ITSQ score was higher in the ≥ 65-years group than in the younger groups with a linear trend of better scores with increasing age (P for trend < 0.05). ADDQoL scores were similar across the age groups, and present QOL (ADDQoL subscale) tended to improve with age (P for trend < 0.05). Achieving HbA1c < 7.0% and individualized targets were associated with satisfaction with insulin treatment regarding glycemic control.

Conclusion

In Japanese adults with T1D, the impact on psychosocial aspects and QOL varied across age groups, with a trend of improving scores with age, potentially in relation to the less stringent glycemic control targets adopted in older individuals. Glycemic control was significantly associated with treatment satisfaction.

The relationship between well-being and HbA1c in adults with type 1 diabetes: A systematic review

BACKGROUND

Diabetes has been associated with psychological problems, which in turn have been related to poorer glycemic control (glycosylated hemoglobin [HbA1c]). On the contrary, psychological well-being constructs have been associated with superior medical outcomes, including better HbA1c.

AIM

The main objective of this study was to systematically review the existing literature about the relationships between subjective well-being (SWB) and HbA1c in adults with type 1 diabetes (T1D).

METHODS

Comprehensive searches were conducted in PubMed, Scopus, and Medline, time restricted to 2021, for studies examining the link between HbA1c and the cognitive (CWB) and affective (AWB) components of SWB. A total of 16 eligible studies were selected according to the inclusion criteria, of which 15 measured CWB and 1 AWB.

RESULTS

Of the 15 studies included, 11 showed a relationship between CWB and HbA1c, with a higher level of HbA1c being related to poorer CWB. The other four studies did not find any significant association. Finally, the only study examining the relationship between AWB and HbA1c found a marginally association between these variables in the expected direction.

CONCLUSION

The overall data suggest that CWB is negatively related to HbA1c in this population, but these results are inconclusive. This systematic review offers clinical implications, such as the possible evaluation, prevention, and treatment of the problems associated with diabetes through the study and training of the psychosocial variables that may directly influence SWB. Limitations and future lines of investigation are discussed.

Modified e-Delphi Process for the Selection of Patient-Reported Outcome Measures for Children and Families With Type 1 Diabetes Using Continuous Glucose Monitors: Delphi Study

BACKGROUND

Type 1 diabetes (T1D) management is complex and associated with significant psychosocial burden. Continuous glucose monitors (CGM) can improve disease management and outcomes and introduce new or exacerbate existing psychosocial concerns. Patient-reported outcome measures (PROMs) can be used to capture this information, but there is no consensus on which PROMs should be used in pediatric CGM research.

OBJECTIVE

Here we describe the process to (1) identify PROMs that could be used to assess the impact of CGMs on pediatric patients with T1D, (2) implement a modified electronic Delphi (e-Delphi) methodology to arrive at an expert consensus on which PROMs are most suitable for clinical and research applications, and (3) establish a periodicity table for the administration of PROMs over time in a real-world evidence study.

METHODS

To identify appropriate PROMs for pediatric patients and families with T1D and CGMs, we conducted an asynchronous, e-Delphi process with a multidisciplinary group of experts from around the country. We identified candidate instruments through a literature review. The 3-round e-Delphi process was conducted via a study website, email, and web-based forms. Participants provided opinions on the usefulness of instruments, age validation, feasibility, time, and frequency of administration.

RESULTS

In total, 16 experts participated in the e-Delphi process; 4 of whom consistently participated in all 3 rounds. We identified 62 candidate instruments, which were narrowed down to 12 final PROMs across 5 domains: diabetes distress and burden (n=4), autonomy (n=2), quality of life (n=1), psychosocial (n=3), and technology acceptance (n=2). A quarterly administration schedule was developed to reduce burden on participants.

CONCLUSIONS

PROMs can provide critical insights into the psychosocial well-being of patients. The specific measures identified in the paper are particularly well suited for pediatric patients with T1D using CGMs. Clinical implementation could help health care providers, patients, and families to engage in more comprehensive disease management.

Dead in bed - A systematic review of overnight deaths in type 1 diabetes

BACKGROUND

Type 1 diabetes is a significant, life-long condition which affects many people worldwide. One of the most feared causes of type 1 diabetes mortality, overnight mortality, often caused by the dead in bed syndrome, is largely underreported. A systematic literature search was undertaken to understand the frequency, risk factors, causes and impact that diabetes-related technologies have on overnight mortality, in this population.

METHODS

MEDLINE (Ovid), Embase (Ovid) and Cochrane were searched to June 2021, using defined inclusion and exclusion criteria. Quality appraisal was undertaken.

RESULTS

Overall, 26 records met the inclusion criteria. Large-scale cohort studies examined data up to 2013, and there were no studies published after 2018. The proportion of deaths attributable to the dead in bed syndrome was between 2 and 5% of deaths in children, adolescents, and young adults, with a slight decrease in proportion of dead in bed syndrome since 1991.

CONCLUSION

Overnight mortality is occurring for people with type 1 diabetes, reported as recently as in 2018. Living alone, alcohol and illicit substances consistently appear as risk factors, and the impact of technology on overnight mortality is not fully understood, with more recent data, from larger cohort studies being required.

Cultural adaptation and psychometric evaluation of the Kinyarwanda version of the diabetes-39 (D-39) questionnaire

Background

In recent years, more importance is being given to the assessment of quality of life (QoL) among diabetic patients as a measure of their health and the goal of all health interventions. Other studies have reported a high prevalence of diabetes-related effects on; however, there is a knowledge gap in the region of Sub-Saharan Africa, as is the case for Rwanda, where the prevalence of diabetes is expected to rise over the next decade. The aim of this study is to report on the translation and cultural adaptation of the Diabetes-39 (D-39) questionnaire into the Kinyarwanda and its psychometric properties among diabetic patients in Rwanda.

Methods

The D-39 questionnaire—a five-scale, disease-specific QoL questionnaire—was translated from English to Kinyarwanda, then back-translated to English. A consensus meeting discussed discrepancies and agreed on changes. Interviews were conducted with 26 participants before producing a final version. For the psychometric evaluation, the adapted version was administered to 309 patients with diabetes mellitus. Participants either came from a separate cluster-randomised controlled trial or were recruited ad hoc for this study. The evaluation included testing internal consistency, known group validity, and construct validity.

Results

Participants’ mean age was 51 ± 12.7 years with a predominance of women (64%) in the sample. All five scales of the questionnaire showed a good internal consistency, with composite reliability of above 0.7. The five-factor model of the questionnaire was fitted to the 39 items. Although the fit was not exact, there was a satisfactory approximate fit (CFI = 0.93, TLI = 0.92, RMSEA = 0.05). There was a good discriminant validity except for the “social burden” and “anxiety and worry” scales (inter-factor correlation = 0.80).

Conclusions

Diabetes-39 is a questionnaire developed in English that was adapted and translated into Kinyarwanda. The Kinyarwanda version of D-39 is a reliable and valid instrument to measure QoL among diabetic patients in Rwanda. The questionnaire can be helpful in research and clinical practice improving health outcomes for patients with diabetes in Rwanda and other Kinyarwanda-competent areas in the sub-region. However, certain cross-cultural differences should be considered.

Quantitative and qualitative analysis of the quality of life of Type 1 diabetes patients using insulin pumps and of those receiving multiple daily insulin injections

Introduction

Insulin pump therapy represents an alternative to multiple daily injections and can improve glycemic control and quality of life (QoL) in Type 1 diabetes mellitus (T1DM) patients. We aimed to explore the differences and factors related to the T1DM-specific QoL of such patients in Latvia.

Design and methods

A mixed-method cross-sectional study on 87 adult T1DM patients included 20 pump users and 67 users of injections who participated in the quantitative part of the study; 8 pump users and 13 injection users participated in the qualitative part. Patients were invited to participate using a dedicated digital platform. Their QoL and self-management habits were assessed using specially developed questionnaires adapted to Latvian conditions. Multiple logistic regression models were built to investigate the association between social and self-management factors and patients’ QoL. In addition, qualitative analysis of answers was performed.

Results

Insulin pump users were younger, had higher incomes, and reported higher T1DM expenses than users of multiple daily injections. There were no differences in self-management between the groups; Total QoL differed at the 0.1 significance level. In fully adjusted multiple logistic regression models, the most important factor that increased Total QoL was lower T1DM-related expenses (odds ratio, OR 7.02 [95% confidence interval 1.29; 38.0]). Men and those with more years of living with T1DM had better QoL (OR 9.62 [2.20; 42.1] and OR 1.16 [1.05; 1.29], respectively), but the method of administration was not significantly associated with QoL (OR 7.38 [0.87; 62.9]). Qualitative data supported the results of quantitative analysis.

Conclusions

QoL was the main reason to use an insulin pump, while the expense was the main reason to avoid the use of it or to stop using it. Reimbursement policies thus should be considered to enable patients to choose the more convenient method for themselves.

Determinants of healthful eating and physical activity among adolescents and young adults with type 1 diabetes in Qatar: A qualitative study

BACKGROUND

In Qatar, as in the rest of the world, the sharp rise in the prevalence of type 1 diabetes (T1D) is a leading cause for concern, in terms associated with morbidity, mortality, and increasing health costs. Besides adhering to medication, the outcome of diabetes management is also dependent on patient adherence to the variable self-care behaviors including healthful eating (HE) and physical activity (PA). Yet, dietary intake and PA in adolescents and young adults (AYAs) with T1D are known to fall short of recommended guidelines. The aim of this study was to develop an in-depth understanding of the behavioral determinants of HE and PA adherence among Arab AYAs within the age range of 17-24 years with T1D attending Hamad General Hospital.

METHODS

Semi-structured, face-to-face individual interviews were conducted with 20 participants. Interviews were based on an integrative health behavior change model, the I-Change model (ICM). All interviews were audio-recorded, transcribed verbatim, and analyzed using the framework method.

RESULTS

More participants reported non-adherence than adherence. Several motivational determinants of adherence to HE and PA were identified. The majority of participants were cognizant of their own behaviors towards HE and PA. Yet, some did not link low adherence to HE and PA with increased risks of health problems resulting from T1D. Facilitators to adherence were identified as being convinced of the advantages of HE and PA, having support and high self-efficacy, a high level of intention, and a good health care system.

CONCLUSION

The suboptimal adherence in AYAs to HE and PA needs more attention. Supportive actions are needed to encourage adherence to a healthy lifestyle to achieve benefits in terms of glycemic control and overall health outcomes, with a special focus on adolescents. Interventions are needed to foster motivation by addressing the relevant determinants in order to promote adherence to these two behaviors in AYAs with T1D.

A fully artificial pancreas versus a hybrid artificial pancreas for type 1 diabetes: a single-centre, open-label, randomised controlled, crossover, non-inferiority trial

BACKGROUND

For people with type 1 diabetes, there is currently no automated insulin delivery system that does not require meal input. We aimed to assess the efficacy of a novel faster-acting insulin aspart (Fiasp) plus pramlintide fully closed-loop system that does not require meal input.

METHODS

In this open-label, randomised controlled, crossover, non-inferiority trial we compared the Fiasp (Novo Nordisk, Bagsværd, Denmark) plus pramlintide closed-loop system with no meal input (fully artificial pancreas) and the Fiasp-alone closed-loop system with precise carbohydrate counting (hybrid artificial pancreas). Adults (≥18 years) who had a clinical diagnosis of type 1 diabetes for at least 12 months, had glycated haemoglobin 12% or lower, and had been on insulin pump therapy for at least 6 months were enrolled at McGill University Health Centre, Montreal, QC, Canada. The Fiasp plus pramlintide fully closed-loop system delivered pramlintide in a basal-bolus manner with a fixed ratio of 10 μg:U relative to insulin. A research staff member counted the carbohydrate content of meals to input in the hybrid closed-loop system. Participants completed the two full-day crossover interventions in a random order allocated by a computer-generated code implementing a blocked randomisation (block size of four). The primary outcome was the percentage of time spent within the glucose target range (3·9-10·0 mmol/L), with a 6% non-inferiority margin, assessed in all participants who completed both interventions. This trial is registered with ClinicalTrials.gov, NCT03800875.

FINDINGS

Between Feb 8, 2019, and Sept 19, 2020, we enrolled 28 adults, of whom 24 completed both interventions and were included in analyses. The percentage of time spent in the target range was 74·3% (IQR 61·5-82·8) with the fully closed-loop system versus 78·1% (66·3-87·5) with the hybrid Fiasp-alone closed-loop system (paired difference 2·6%, 95% CI -2·4 to 12·2; non-inferiority p=0·28). Eight (33%) participants had at least one hypoglycaemia event (<3·3 mmol/L) with the fully closed-loop system compared with 14 (58%) participants with the hybrid closed-loop system (2200-2200 h). Non-mild nausea was reported by three (13%) participants and non-mild bloating by one (4%) participant with the fully closed-loop system compared with zero participants with the hybrid closed-loop system.

INTERPRETATION

The Fiasp plus pramlintide fully closed-loop system was not non-inferior to the Fiasp-alone hybrid closed-loop system for the overall percentage of time in the glucose target range. However, participants still spent a high percentage of time within the target range with the fully-closed loop system. Outpatient studies comparing the fully closed-loop hybrid systems with patient-estimated, rather than precise, carbohydrate counting are warranted.

Patient-reported outcomes in adults with type 1 diabetes in global real-world clinical practice: The SAGE study

AIMS

To conduct a secondary analysis of the SAGE study to evaluate the association between glycaemic control and patient-reported outcomes (PROs), in adults with type 1 diabetes (T1DM) across different age groups and regions.

MATERIALS AND METHODS

SAGE was a multinational, cross-sectional, observational study in adults with T1DM. Data were collected at a single visit, analysed according to predefined age groups (26-44, 45-64, and ≥65 years), and reported across different regions. PRO questionnaires were applied to assess hypoglycaemia fear (Hypoglycemia Fear Survey-II), diabetes-related distress (Problem Areas In Diabetes questionnaire), insulin treatment satisfaction (Insulin Treatment Satisfaction Questionnaire), and diabetes-specific quality of life (QoL; Audit of Diabetes-Dependent Quality of Life). Multivariable analysis was performed to evaluate the relationship between glycated haemoglobin (HbA1c) target achievement (<7% and individualised targets) with PRO scores.

RESULTS

The PRO scores showed relatively low levels of diabetes-related emotional distress and fear of hypoglycaemia, moderate to high treatment satisfaction, and low diabetes-related impact on QoL. Results were generally comparable across age groups with some regional variability. Achievement of the HbA1c <7% target was associated with less worry about hypoglycaemia, lower diabetes-related emotional distress, higher insulin treatment satisfaction, and higher QoL. Achievement of individualised HbA1c targets was associated with lower diabetes-related emotional distress and higher insulin treatment satisfaction.

CONCLUSIONS

Better glycaemic control was most closely associated with low emotional distress due to diabetes and high patient-reported insulin treatment satisfaction.

Reliability and Validity of Ethiopian Amharic Version of the PedsQLTM 4.0 Generic Core Scales and PedsQLTM 3.0 Diabetes Module

BACKGROUND

The PedsQLTM 4.0 generic core scales (GCS) assess the generic health by integrating with disease-specific PedsQLTM 3.0 diabetes module (DM). The PedsQLTM 3.0 DM measures the health-related quality of life (HrQoL) specific to diabetes. Even though there is no translation to Ethiopian Amharic, the instruments had translated to different languages and validated. The study is aimed to assess the validity and reliability of the Amharic version of the PedsQLTM 4.0 GCS and the PedsQLTM 3.0 DM in children and adolescents with diabetes.

METHODS

PedsQLTM 4.0 GCS and the PedsQLTM 3.0 DM were administered on 193 children and adolescents with diabetes and their parents. The validity was examined by the exploratory factor analysis, multitrait/multi-item scaling analysis, and multitrait-multimethod and monotrait-multimethod analysis. Cronbach's alpha coefficient checked the reliability.

RESULTS

Cronbach's alpha coefficient for the total PedsQLTM 4.0 GCS (α child self-report= 0.96; α parent proxy report= 0.95) and for total PedsQLTM 3.0 DM (α child self-report= 0.96; α parent proxy report=0.93) were acceptable at individual patient-level analysis. The monotrait-multimethod correlations were higher than multitrait-multimethod correlations. In multitrait/multi-item scale analysis, both total PedsQLTM 4.0 GCS and PedsQLTM 3.0 DM had an excellent item convergent and discriminatory validity success rate.

CONCLUSION

The Amharic versions of the PedsQLTM 4.0 GCS and the PedsQLTM 3.0 DM were valid and reliable instruments to measure the HrQoL of children and adolescents with diabetes.

A cross-sectional study of the quality of life of patients living with type 1 diabetes treated with insulin glargine and neutral protamine Hagedorn insulin and the implications

Objectives

The study aim was to identify key factors associated with the health-related quality of life (HRQOL) of patients with type 1 diabetes mellitus (T1DM) treated with neutral protamine Hagedorn (NPH) insulin or human insulin analog glargine (IGLA).

Methods

We conducted two cross-sectional studies in Minas Gerais State, Brazil. One with 401 patients treated with IGLA, and the other with 179 T1DM patients treated with NPH. HRQOL was measured by Euroqol (EQ-5D-3L).

Key findings

Most participants were male (51%), aged between 18 and 40 years (47%), non-black (58%) and from the highest economic strata (A1-B2) (74%). Participants perceived their health as good/very good (51%), had one to three medical consultations in the previous year (51%), were not hospitalized in the previous year (74%), did not report angina (96%), diabetic neuropathy (90%), hearing loss (94%) or kidney disease (89%). Non-severe hypoglycaemia episodes in the last 30 days were reported by 17% of participants.

Conclusions

Higher HRQOL was associated with younger age (18–40 years), good/very good health self-perception, having had up to three medical consultations in the last year, not being hospitalized in the last year, having none to three comorbidities, not reporting angina, diabetic neuropathy, hearing loss or kidney disease and having had episodes of non-severe hypoglycaemia. In addition, the findings of our study demonstrated inequalities in access to treatment, which will be the subject of future research projects.

Delayed effect of different exercise modalities on glycaemic control in type 1 diabetes mellitus: A systematic review and meta-analysis

BACKGROUND AND AIMS

Despite the crucial role of exercise in the prevention of comorbidities and complications in type 1 diabetes mellitus (T1DM), people living with the disease are often insufficiently physically active, mainly due to the fear of hypoglycaemia. Research using continuous glucose monitoring (CGM) devices has shown that exercise affects glycaemic control in T1DM for over 24 h. The aim of this systematic review and meta-analysis is, therefore, to investigate the delayed effects of different exercise modalities on glycaemic control in adults with T1DM.

METHODS AND RESULTS

The literature search of experimental studies was conducted on PubMed, SPORTDiscus and EMBASE from January 2000 to September 2019. Twelve studies using CGM devices were included. Compared to endurance, intermittent exercise increased the time spent in hypoglycaemia (0.62, 0.07 to 1.18; standardised effect size, 95% CI) and reduced the mean interstitial glucose concentration (-0.88, -1.45 to -0.33). No differences emerged in the time spent in hyperglycaemia (-0.07, -0.58 to 0.45) or in the proportion of exercisers experiencing hypoglycaemic events (0.82, 0.45 to 1.49; proportion ratio, 95% CI) between conditions. The systematic review also found a reduced risk of hypoglycaemia if exercise is performed in the morning rather than in the afternoon, and with a 50% rapid-acting insulin reduction. It was not possible to determine the benefits of resistance exercise.

CONCLUSIONS

For the first time, we systematically investigated the delayed effect of exercise in adults with T1DM, highlighted undetected effects, shortcomings in the existing literature, and provided suggestions to design future comparable studies.

Motivational Interviewing and Self-Care in Type 1 Diabetes: A Randomized Controlled Clinical Trial Study Protocol

Background

Type 1 diabetes is a disease with complex therapeutic recommendations that require day-to-day lifestyle changes. Motivational Interviewing is a communication tool that has proved effective in changing behaviors in people with addictions, obesity and type 2 diabetes. Our objective is to evaluate the effects of a Motivational Interviewing intervention in people with type 1 diabetes.

Methods

Sixty-six patients with type 1 diabetes and hemoglobin A1c >= 8% have been included and randomly assigned (computer-generated sequence, sealed envelopes, ratio 1:1) either to the intervention or to the control group. In the intervention group, appointments every 4 months with the endocrinologist include Motivational Interviewing; in the control group, the appointments proceed as usual. Patients will be followed for 16 months. The primary outcome will be self-care behaviors, assessed by a validated questionnaire, the Diabetes Self-Care Inventory-Revised Version. Secondary outcomes include: HbA1c, motivation for self-care, self-efficacy, health-related quality of life, satisfaction with professional-patient relationship, and fulfillment of patients' own objectives. The practitioners receive training in Motivational Interviewing in order to help them promote adherence to self-care, encourage patient motivation and improve the doctor-patient relationship. The Motivational Interviewing intervention will be evaluated by two psychologists, blinded to the assigned treatment, through video recordings of the sessions and the administration of a purpose-built questionnaire, the EVEM 2.0 scale.

Discussion

There is evidence that MI can improve self-care in type 2 diabetes. In this study, we aim to evaluate the effect of MI on self-care and HbA1c in people with type 1 diabetes.

The comparison of efficacy and safety between different doses of empagliflozin in insulin-treated type 1 diabetes mellitus patients: a systematic review and meta-analysis protocol

Objectives

The proposed review aims to compare the efficacy and safety profile of empagliflozin 25 mg with its lower dosages and placebo, respectively, in insulin-treated type 1 diabetes mellitus (T1DM) patients.

Methods

Double-blinded randomized controlled trials comparing the above outcomes will be searched primarily in three electronic databases (PubMed, Embase, and Scopus) and eligible trials will be included in the proposed review. Then, from the trials recruited in the review, data of the study design, participants, interventions compared, and outcomes of interest will be extracted. Subsequently, the trials' risk of bias will be assessed using the Cochrane Collaboration's tool. The meta-analysis will be conducted with a fixed-effect or a random-effect model to estimate the mean differences (weighted or standardized) and risk ratios for the efficacy and safety-related comparable outcome data, respectively. Statistical heterogeneity will be assessed by the p-value of chi-squared statistics and I² statistics and explained by subgroup analysis and meta-regression. Publication bias will be assessed by funnel plots and Egger's test. The sensitivity analysis will repeat the meta-analysis for respective outcomes using assumptions alternative to that used in the preliminary meta-analysis and by dropping each study at a time.

Results

A narrative reporting will ensue if a meta-analytic comparison is not possible.

Conclusions

Based on the contemporary literature, the proposed review will synthesize the evidence on how the efficacy and safety profile of high dose empagliflozin varies with its lower doses and placebo, respectively, in insulin-treated T1DM patients.

The Effect of Intelligence Self-Control Program on the Quality of Life of the Adolescents with Type I Diabetes

Background:

Diabetes affects patients’ quality of life in almost all physical, mental, and social areas. The aim of the present study was to determine the effect of self-control intelligence program on the dimensions of quality of life in the adolescents with diabetes.

Materials and Methods:

The present study is a randomized controlled trial with pre-test and post-test design in which 56 adolescents with diabetes referring to the Janan charity diabetic association in Najafabad in 2018 (Isfahan, Iran) were selected by convenience sampling method and were randomly divided into two groups of intervention (n = 28) and control (n = 28). Self-control intelligence program was performed for the intervention group. The data were collected using standard Quality of Life Questionnaire for adolescents with diabetes and were analyzed using Chi-square test, independent and dependent t-test, Mann-Whitney.

Results:

Statistical tests showed no significant difference between the groups in terms of their demographic characteristics such as gender, duration of diabetes, and the number of insulin injections. There was, however, a significant difference in the mean scores of all quality of life dimensions except for the dimension of physical symptoms both before and after the intervention in the intervention group (t₂₃ = 4.46, p < 0.001). By contrast, no significant difference was observed in the mean scores of quality of life before and after the intervention in the control group (t₂₄ = 0.08, p = 0.93).

Conclusions:

Based on the results, self-control program can have an effective role in the adoption of coping strategies and, thus, improves the patients’ quality of life.

A systematic review and meta-analysis of randomized controlled trials, juxtaposing the control of glycemia and blood pressure between large dose empagliflozin and placebo among type 1 diabetes patients

OBJECTIVES

While empagliflozin (25 mg) is used to treat type-2 diabetes mellitus patients with optimum renal functioning, its efficacy and safety in type-1 diabetes mellitus (T1DM) is not yet established. Therefore, this study aimed to compare insulin-treated T1DM patients' (with adequate renal functioning) glycemic and blood pressure control between the 25 mg empagliflozin recipients and placebo recipients.

METHODS

Parallel-arm randomized controlled trials comparing the effect of daily administered 25 mg empagliflozin tablets in adjunct to insulin treatment with placebo and insulin treatment in T1DM patients with an estimated glomerular filtration rate of 45 mL/min/1.73 m² or more were eligible for inclusion. Trials were searched in PubMed, EMBASE, SCOPUS, and CENTRAL with no restriction on date and language. Risk of bias of trials was assessed and mean and standard deviation of glycated hemoglobin (HbA1c, in %), systolic blood pressure (mmHg), and diastolic blood pressure (mmHg) at the end of the trial period were collected, and random-effects meta-analysis was done to estimate the weighted mean difference (WMD). The meta-analysis was done in Stata statistical software. This study was conducted in June 2019.

RESULTS

Three relatively small-sized trials published between 2015 and 2018 were eligible for review and analyses. The trials suffered from unclear risk of performance and detection bias. The HbA1c reduction favored the intervention group (WMD = -0.478, 95% confidence intervals = -0.766--0.189, P = 0.001; I² = 0%). The WMD of blood pressure (systolic and diastolic) did not vary between the treatment groups.

CONCLUSION

Evidence (of moderate quality) suggests that daily administration of empagliflozin 25 mg tablets in adjunct to insulin in T1DM patients with optimum kidney functioning is useful to achieve glycemic control compared to placebo and insulin therapy. However, the effect on blood pressure remained indistinguishable between the compared interventions.

Defining High Glycemic Variability in Type 1 Diabetes: Comparison of Multiple Indexes to Identify Patients at Risk of Hypoglycemia

Background: International consensus on the use of continuous glucose monitoring (CGM) recommends coefficient of variation (CV) as the metric of choice to express glycemic variability (GV) with a cutoff of 36% to define unstable diabetes. Even though, CV is associated with hypoglycemia in type 2 diabetes patients, the evidence on the use of one particular measure of GV in type 1 diabetes (T1DM) patients as a predictor of hypoglycemia is limited. Methods: A cohort of T1DM ambulatory patients was evaluated using CGM. Number and incidence rate of events <54 and <70 mg/dL were calculated. Bivariate and multivariate analysis of different glycemic indexes and clinical variables were performed to identify those associated with hypoglycemia. Receiver operating characteristic (ROC) curve analysis for each of the glycemic indexes was performed to define the best index and its optimal cutoff threshold to discriminate patients with events of hypoglycemia. Results: Seventy-three patients were included. A total of 128 events <54 mg/dL were recorded in 34 patients, and 350 events <70 mg/dL were registered in 51 patients. CV was the only variable significantly associated with hypoglycemia <54 mg/dL in the multivariate analysis (adjusted relative risk [aRR] 1.44, 95% confidence interval [CI]: 1.10-1.88, P = 0.008). CV, HbA1c (glycated hemoglobin), and mean glucose were associated with events <70 mg/dL. ROC curve analysis showed that, among GV metrics, CV had the best performance to discriminate patients with events <54 mg/dL (area under the curve [AUC] 0.87, 95% CI: 0.79-0.95) and events <70 mg/dL (AUC 0.79, 95% CI: 0.68-0.90) with optimal cutoff thresholds values of 34% and 31%, respectively. Among glycemic risk (GR) indexes, low blood glucose index (LBGI) showed the best performance. Conclusions: This analysis shows that CV is the best GV index, and LBGI the best GR index, to identify patients at risk of clinically significant hypoglycemia and hypoglycemia alert events in T1DM patients.

Assessment of Alimentación Normal con Ajuste de Insulina (ANAIS), a Spanish version of the DAFNE programme, in people with Type 1 diabetes: a randomized controlled parallel trial

AIM

To evaluate the effects of Alimentación Normal con Ajuste de Insulina (ANAIS), a group-based, therapeutic education programme for Type 1 diabetes based on a flexible insulin regimen adjusted to the individual's food intake.

METHODS

Participants with Type 1 diabetes and HbA_1c levels of 53-86 mmol/mol (7-10%) were recruited from outpatient clinics at a tertiary care centre. They were randomized (using opaque, sealed envelopes, with a 2:1 treatment allocation ratio) to attend the training course immediately (immediate ANAIS; intervention group) or a year later (delayed ANAIS; control group). The main outcome was HbA_1c level at 1 year. Secondary outcomes included lipid levels, weight, hypoglycaemic events, insulin dose, treatment satisfaction, self-perceived dietary freedom, quality of life and participant-defined goals.

RESULTS

A total of 48 participants were assigned to the intervention group and 32 to the control group. Twelve months after completing the training, adjusted HbA_1c was not significantly different in the intervention group [64 ± 1.3 vs 68 ± 1.6 mmol/mol (8.0 ±0.1% vs 8.4 ±0.1%); P=0.081]. Treatment satisfaction was significantly higher in the intervention group, but no differences were found in hypoglycaemic events, weight, insulin dose or changes in dietary freedom. At 1 year after the intervention, 72% of the participants (vs 33% in the control group; P=0.046) reported exceeding their expectations regarding achievement of their main personal goal.

CONCLUSION

Promoting dietary freedom and empowering people with Type 1 diabetes through structured education programmes, such as ANAIS, improves treatment satisfaction and self-defined goals. No significant improvement in HbA_1c level was achieved.

A Preliminary Study on "PRISMA" Education in Improving Self-Management and Level of Compliance in Children with Type-1 Diabetes Mellitus

Children with Type-1 Diabetes Mellitus (TIDM) need long-term care that requires supervision. Without good management, there will be an increase in blood glucose, which can cause complications in organs and tissues. One way to improve self-management and level of compliance in blood glucose control is by providing education. This study aimed to determine the effect of PRISMA education on self-management and level of compliance in children with T1DM. This study used a quasi-experimental design with no control group. PRISMA education using animated videos was given to the respondents who filled out the questionnaire about self-management and level of compliance (pre-test) and were evaluated on the eighth day (post-test). The sample of this study consisted of 31 children in Jakarta, Bogor, Depok, and Tangerang. The results of this study indicate that PRISMA education had significant effects on self-management (p < 0.05) and level of compliance (p < 0.05). The delivery of self-management education in the form of animated videos could improve self-management and children's compliance in the management of diet, physical act, treatment, stress management and blood glucose control. Thus, this educational tool could be useful if it is integrated into nursing interventions, especially in the field of pediatric nursing.

The prevalence of neuropathy among type 1 diabetic adolescents in Iran: a systematic review and meta-analysis

INTRODUCTION

Neuropathy is one of the most common complications of diabetes, which causes many problems for diabetic patients. Thus, the aim of the present study was to investigate the prevalence of neuropathy among type 1 diabetic adolescents by systematic review and meta-analysis.

MATERIALS AND METHODS

This study is a systematic review and meta-analysis, which reviewed articles published from 2001 to September 1, 2018. The search process was carried out in the Google Scholar search engine and domestic and international databases such as Magiran, SID, Iranmedex, IranDoc, Medlib, PubMed, Scopus, Science Direct, Springer, Wiley Online Library, Web of Science, Ebsco and Cochrane using Persian and English keywords based on MESH conformity. All the research steps were carried out by two members of the research team who were familiar with systematic reviews and meta-analysis data, using the software CMA. Analysis of meta-regression and the use of a random effects model were introduced and analyzed.

FINDINGS

When a systematic search was carried out on the reviewed articles, five of them were included in the meta-analysis phase. The sample size was 484, and the prevalence of diabetic peripheral neuropathy (DPN) in type 1 diabetic patients was 28.2% [confidence interval (CI) = 19.5-39.1]. The findings of the meta-regression analysis showed that the DPN prevalence rate decreased with increasing age (Q = 5.77 p = 0.016), and the results of more recent studies showed an increase in the DPN incidence rate (Q = 20.62, p < 0.001).

CONCLUSION

The findings of the present study revealed that although the prevalence of neuropathy in diabetic adolescents was not high, the prevalence was significant. Considering the increasing prevalence of diabetes and its impact on the health status of patients, appropriate interventions should be conducted to prevent diabetes and subsequent diabetic neuropathy.

Health-related quality of life in diabetes mellitus and its social, demographic and clinical determinants: A nationwide cross-sectional survey

AIMS AND OBJECTIVES

To investigate health-related quality of life in a representative sample of adults with diabetes mellitus in Spain, as well as its clinical and sociodemographic determinants.

BACKGROUND

Diabetes mellitus is a chronic disease causing considerable morbidity and mortality worldwide, resulting in an impaired quality of life in affected people.

DESIGN

A nationwide cross-sectional study, based on an online survey and carried out between February-March 2016, was performed on diabetic subjects recruited through diabetic patients' organisations.

METHODS

A validated Spanish-language version of the self-administered Diabetes Quality of Life questionnaire was used, with 0 being the worst and 100 the best QoL level. Determinant factors of health-related quality of life were assessed with the aid of multivariate analysis to control for confounding factors.

RESULTS

The responses provided by 456 patients (52.4% being women) revealed an overall mean score of 66.4 ± 13.3. Social/vocational worries and diabetes-related worries were the dimensions with the highest (74.3 ± 20.1) and lowest (61.1 ± 20.6) scores, respectively. Younger age, female gender, having no studies and poor glycaemic control were all independent determinants for an impaired overall health-related quality of life, with most of these factors having a higher impact than the dimensions negative impact of therapy on daily life, satisfaction with therapy and diabetes-related worries. Married (or equivalent) subjects had better scores in the diabetes-related worries dimension. The perception of health-related quality of life progressively worsens as glycaemic control deteriorates and with an increased number of disease complications. Most of the associations did not vary significantly with the type of diabetes mellitus.

CONCLUSION

Overall health-related quality of life perception in the Spanish diabetic population is moderate and depends on several sociodemographic factors. Adequate glycaemic control to avoid disease complications improves perception.

RELEVANCE TO CLINICAL PRACTICE

The results can help health professionals to develop strategies to promote diabetic patient self-care, in order to improve the metabolic control of the disease and avoid its complications, as a therapeutic goal towards an improvement in health-related quality of life perception.

ViDa1: The Development and Validation of a New Questionnaire for Measuring Health-Related Quality of Life in Patients with Type 1 Diabetes

This study describes the development of a new questionnaire to measure health-related quality of life (HRQoL) in patients with type 1 diabetes (the ViDa1 questionnaire) and provides information on its psychometric properties. For its development, open interviews with patients took place and topics relevant to patients' HRQoL were identified and items were generated. Qualitative analysis of items, expert review, and refinement of the questionnaire followed. A pilot study (N = 150) was conducted to explore the underlying structure of the 40-item ViDa1 questionnaire. A Principal Component Analysis (PCA) was performed and six of the items that did not load on any of the factors were eliminated. The results supported a four-dimensional structure for ViDa1, the dimensions being Interference of diabetes in everyday life, Self-care, Well-being, and Worry about the disease. Subsequently, the PCA was repeated in a larger sample (N = 578) with the reduced 34-item version of the questionnaire, and a Confirmatory Factor Analysis (CFA) was performed (N = 428). Overall fit indices obtained presented adequate values which supported the four-factor model initially proposed [([Formula: see text] 2601.93) (p < 0.001); Root Mean Square Error of Approximation = 0.060 (CI = 0.056 -0.064)]. As regards reliability, the four dimensions of the ViDa1 demonstrated good internal consistency, with Cronbach's alphas ranging between 0.71 and 0.86. Evidence of convergent-discriminant validity in the form of high correlations with another specific HRQoL questionnaire for diabetes and low correlations with other constructs such as self-efficacy, anxiety, and depression were presented. The ViDa1 also discriminated between different aspects of clinical interest such as type of insulin treatment, presence of chronic complications, and glycemic control, temporal stability, and sensitivity to change after an intervention. In conclusion, the ViDa1 questionnaire presents adequate psychometric properties and may represent a good alternative for the evaluation of HRQoL in type 1 diabetes.
