Continuous glucose monitoring in youth with type 1 diabetes

The Effectiveness of Continuous Glucose Monitoring Devices in Managing Uncontrolled Diabetes Mellitus: A Retrospective Study

This retrospective study aimed to assess the effectiveness of continuous glucose monitoring (CGM) devices in managing uncontrolled diabetes mellitus (DM). The study cohort comprised 25 patients with uncontrolled diabetes who received treatment at an internal medicine resident clinic. The objective was to evaluate the impact of transitioning from self-monitoring of blood glucose (SMBG) to CGM devices on glycemic control, as measured by changes in hemoglobin A1c (HbA1c) levels, average blood glucose levels, hypoglycemic events, time spent within the target blood sugar range, and glucose variability. The findings indicated significant improvements in glycemic control with the adoption of CGM devices, highlighting their potential benefits for optimizing diabetes management. The study is particularly interesting because it was done in an internal medicine continuity clinic with the main participation of the internal medicine residents under the supervision of an endocrinologist. It was not done as the majority of the other studies used CGM in specialized endocrinology clinics.

Cutaneous Reactions to Continuous Glucose Monitoring and Continuous Subcutaneous Insulin Infusion Devices in Type 1 Diabetes Mellitus

BACKGROUND

Continuous glucose monitoring (CGM) and continuous subcutaneous insulin infusion (CSII) are the standard of care for type 1 diabetes in children. There is little reported on device-related skin complications and treatment options. This study documents cutaneous reactions to CGM and CSII devices in children and young adults with type 1 diabetes.

METHODS

One hundred and twenty-one subjects (3-25 years) with type 1 diabetes and CGM and/or CSII use were recruited over a three-month period from the Naomi Berrie Diabetes Center at Columbia University Irving Medical Center. A five-question survey was completed for each subject detailing demographic data, diabetes management, and device-related skin complications.

RESULTS

Sixty percent of subjects reported skin complications related to CGM and/or CSII use. Terms most frequently used to describe cutaneous reactions were "red," "itchy," "painful," and "rash." Subjects who used both CGM and CSII were more likely to report skin problems than those who used only CSII (odds ratio 2.9, [95% confidence interval: 1.2-6.7]; P = .015). There were no associations between skin complications and sex or race/ethnicity. Twenty-two percent of subjects with adverse skin event(s) discontinued use of a device due to their skin problem. Seven percent were evaluated by a dermatologist. Eighty-one percent used a range of products to treat their symptoms, with variable perceived clinical outcomes.

CONCLUSIONS

Skin complications related to CSII or CGM devices are commonly reported in pediatric patients with type 1 diabetes and may lead to interruption or discontinuation of device use. Future studies are needed to elucidate the causes of these reactions and determine the best methods for prevention.

Technological Ecological Momentary Assessment Tools to Study Type 1 Diabetes in Youth: Viewpoint of Methodologies

Type 1 diabetes (T1D) is one of the most common chronic childhood diseases, and its prevalence is rapidly increasing. The management of glucose in T1D is challenging, as youth must consider a myriad of factors when making diabetes care decisions. This task often leads to significant hyperglycemia, hypoglycemia, and glucose variability throughout the day, which have been associated with short- and long-term medical complications. At present, most of what is known about each of these complications and the health behaviors that may lead to them have been uncovered in the clinical setting or in laboratory-based research. However, the tools often used in these settings are limited in their ability to capture the dynamic behaviors, feelings, and physiological changes associated with T1D that fluctuate from moment to moment throughout the day. A better understanding of T1D in daily life could potentially aid in the development of interventions to improve diabetes care and mitigate the negative medical consequences associated with it. Therefore, there is a need to measure repeated, real-time, and real-world features of this disease in youth. This approach is known as ecological momentary assessment (EMA), and it has considerable advantages to in-lab research. Thus, this viewpoint aims to describe EMA tools that have been used to collect data in the daily lives of youth with T1D and discuss studies that explored the nuances of T1D in daily life using these methods. This viewpoint focuses on the following EMA methods: continuous glucose monitoring, actigraphy, ambulatory blood pressure monitoring, personal digital assistants, smartphones, and phone-based systems. The viewpoint also discusses the benefits of using EMA methods to collect important data that might not otherwise be collected in the laboratory and the limitations of each tool, future directions of the field, and possible clinical implications for their use.

Cost of Treating Skin Problems in Patients with Diabetes Who Use Insulin Pumps and/or Glucose Sensors

Background: The use of insulin pump and glucose sensor is advantageous, but unfortunately many experience skin problems. To reduce or overcome skin problems, patients use additional products or change their sets preterm. Therefore, the aim was to investigate costs related to skin problems. Materials and Methods: Two hundred sixty-three patients from four different hospitals in Denmark participated in a cross-sectional survey about skin problems related to insulin pump and/or glucose sensor use. Additional costs aside technology and diabetes treatment were calculated based on adhesives, patches, lotion, and preterm shifts of infusion or sensor sets due to skin problems. Descriptive statistics and linear regression were used. Results: The total costs for all these expenses were 11493.9 U.S. dollars (USD) in 145 pediatric patients and 4843 USD in 118 adult patients. The costs were higher in patients with, than without, skin problems and for skin problems due to the glucose sensor compared with insulin pump. Pediatric patients with eczema and/or wound due to the glucose sensor did cost 154.3 USD more, than patients without these skin problems (P < 0.01). We found a clear dose/response relationship between costs and severity of skin problems, especially in pediatric patients. Conclusions: Our data show that skin problems due to use of insulin pump and/or glucose sensor have significant costs on the Danish welfare system. This leaves an economic incentive for developing more skin-sensitive adhesive for the infusion set and sensors, at least for a certain subgroup of patients.

Artificial Pancreas Control Strategies Used for Type 1 Diabetes Control and Treatment: A Comprehensive Analysis

This paper presents a comprehensive survey about the fundamental components of the artificial pancreas (AP) system including insulin administration and delivery, glucose measurement (GM), and control strategies/algorithms used for type 1 diabetes mellitus (T1DM) treatment and control. Our main focus is on the T1DM that emerges due to pancreas’s failure to produce sufficient insulin due to the loss of beta cells (β-cells). We discuss various insulin administration and delivery methods including physiological methods, open-loop, and closed-loop schemes. Furthermore, we report several factors such as hyperglycemia, hypoglycemia, and many other physical factors that need to be considered while infusing insulin in human body via AP systems. We discuss three prominent control algorithms including proportional-integral- derivative (PID), fuzzy logic, and model predictive, which have been clinically evaluated and have all shown promising results. In addition, linear and non-linear insulin infusion control schemes have been formally discussed. To the best of our knowledge, this is the first work which systematically covers recent developments in the AP components with a solid foundation for future studies in the T1DM field.

Parental Experiences of Continuous Glucose Monitoring in Danish Children with Type 1 Diabetes Mellitus

PURPOSE

To explore parents 'experience of having a child aged 4-9 years with type 1 diabetes mellitus (T1DM) using continuous glucose monitor (CGM).

DESIGN AND METHODS

The study was a qualitative study. Twelve families were recruited for individual or dyadic interviews through purposeful and convenience sampling procedures.

RESULTS

Thematic analysis generated three main themes: 1) Living in the context of the unpredictability of diabetes 2) Establishing a sense of control and security with the CGM 3) Learning to use and trust the CGM and educating other caregivers.

CONCLUSIONS

Living in the context of the unpredictability of T1DM causes a loss of stability and control as T1DM pervades family life and transforms everyday routines. CGM use seems to increase opportunities for other family activities, as it provides parents with a sense of control and moderates the pervasiveness of T1DM. Yet the parents have to learn how to trust and use the CGM and take on the burdensome task of training and trusting other caregivers.

PRACTICE IMPLICATIONS

The CGM is used as an integral part of T1DM care in everyday life. Therefore, it should be accessible to families. Health-care professionals should be aware of how to assist parents with how to use and trust the CGM. Furthermore, parents may need help and support in educating other caregivers on how to use the CGM. This could be done through teaching sessions, written materials and recorded demonstrations of CGM use.

Cutaneous Complications With Continuous or Flash Glucose Monitoring Use: Systematic Review of Trials and Observational Studies

BACKGROUND

Continuous glucose monitoring (CGM)/flash glucose monitoring (FGM) use in diabetes management is increasing. Cutaneous complications associated with these devices were reported. We conducted a systematic review to provide an overview of cutaneous complications with CGM/FGM use.

METHODS

We identified observational studies and intervention trials that report on cutaneous complications with CGM/FGM use up to January 14, 2019. Studies were identified through Medline, Embase, and PubMed, or with hand searching of the previous publications. Screening was duplicated and data extracted to consider four main themes: incidence rate and severity, participant perspectives of cutaneous complications, potential solutions, and future directions in diabetic technology relevant to reducing cutaneous complications.

RESULTS

A total of 54 eligible studies were identified. The overall event rate of cutaneous complications reported from 19 trials was one event per eight weeks of sensor wear-time of which 1.5% were considered severe. The most common cutaneous complications were wear-related erythema, itching, and induration. Although skin irritations were the most common cause of CGM/FGM discontinuation, most users experienced less pain or discomfort with CGM/FGM than capillary blood glucose testing. Future technological advances may reduce, but not eliminate cutaneous complications.

CONCLUSION

The incidence rate of reported cutaneous complications with CGM/FGM use from the available literature is low, with one event per eight weeks of sensor wear-time. Reported complication severity was also low, leading to low rates of CGM/FGM discontinuation. However, there appear to be discrepancies between reporting in trial and observational data. Greater constancy in reporting is necessary to understand the frequency of this issue.

The Progress of Glucose Monitoring-A Review of Invasive to Minimally and Non-Invasive Techniques, Devices and Sensors

Current glucose monitoring methods for the ever-increasing number of diabetic people around the world are invasive, painful, time-consuming, and a constant burden for the household budget. The non-invasive glucose monitoring technology overcomes these limitations, for which this topic is significantly being researched and represents an exciting and highly sought after market for many companies. This review aims to offer an up-to-date report on the leading technologies for non-invasive (NI) and minimally-invasive (MI) glucose monitoring sensors, devices currently available in the market, regulatory framework for accuracy assessment, new approaches currently under study by representative groups and developers, and algorithm types for signal enhancement and value prediction. The review also discusses the future trend of glucose detection by analyzing the usage of the different bands in the electromagnetic spectrum. The review concludes that the adoption and use of new technologies for glucose detection is unavoidable and closer to become a reality.

Biopsychosocial Factors Associated With Satisfaction and Sustained Use of Artificial Pancreas Technology and Its Components: a Call to the Technology Field

PURPOSE OF REVIEW

Summarize biopsychosocial factors associated with using continuous glucose monitors (CGMs), insulin pumps, and artificial pancreas (AP) systems and provide a "call to the field" about their importance to technology uptake and maintained use.

RECENT FINDINGS

Insulin pumps and CGMs are becoming standard of care for individuals with type 1 diabetes (T1D). AP systems combining a CGM, insulin pump, and automated dosing algorithm are available for commercial use. Despite improved glycemic control with AP system use, numerous barriers exist which may limit their benefit. Studies on components of AP systems (pumps, CGMs) are limited and demonstrate mixed results of their impact on fear of hypoglycemia, adherence, quality of life, depression and anxiety, and diabetes distress. Studies examining biopsychological factors associated specifically with sustained use of AP systems are also sparse. Biological, psychological and social impacts of AP systems have been understudied and the information they provide has not been capitalized upon.

High frequencies of dermatological complications in children using insulin pumps or sensors

BACKGROUND

Dermatological complications in children and adolescents that are related to continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM) have not been well-characterized. This study examined the prevalence and characteristics of different types of dermatological complications.

METHODS

Online questionnaires regarding dermatological complications related to CSII and/or CGM were returned from a total of 144 children and adolescents, aged 2 to 20 years. Both previous and current skin problems were reported along with their clinical characteristics. Descriptive statistics, χ² tests, and multivariate analyses were used to evaluate the data.

RESULTS

Of 143 patients using CSII, 90% had previous and 63% reported current dermatological complications. Non-specific eczema was most frequently reported and was currently present in 25.7% of the patients. These results were independent of age and current CGM use. Among the 76 patients using CGM, 46% reported current dermatological complications. A history of atopy was associated with dermatological complications in individuals using CSII, but not CGM. The patients rated CGM-related dermal issues as significantly worse than those associated with CSII (P < .05).

CONCLUSIONS

Dermatological complications can be a serious problem in treating pediatric and adolescent patients of all ages with CSII and/or CGM. Only a few clinical characteristics associated with these complications were identified in this study, highlighting the need for prospective studies that might lead to improvements in the prevention and treatment of dermatological problems.

Initial versus ongoing education: Perspectives of people with type 1 diabetes in 13 countries

PURPOSE

To understand the perspectives of people with type 1 diabetes with regards to the diabetes education they receive within the health system.

METHODS

Grounded Theory was used for the collection and analysis of data from interviews with 101 people with type 1 diabetes from 13 countries.

RESULTS

There are two aspects to education, namely initial education received when diagnosed and the ongoing education people continue to receive. Within these two categories content and process of diabetes education are important as are factors linked to the healthcare worker and setting.

CONCLUSIONS

Tangible elements are the "what" that is delivered and are the different skills and information needed for people to manage their diabetes. Process elements are the "how" this is delivered. Finally intangible elements are those, which were found to be specific to certain contexts and health professionals. These could be the hardest to replicate, but possibly the most important.

PRACTICE IMPLICATIONS

Health systems can provide the tangible elements and organize themselves to have processes in place to deliver education. The challenge is how can the intangible elements be seen as important and developed and delivered to improve management, but also meet the needs of people with diabetes.

Sensor and software use for the glycaemic management of insulin-treated type 1 and type 2 diabetes patients

Lowering glucose levels, while avoiding hypoglycaemia, can be challenging in insulin-treated patients with diabetes. We evaluated the role of ambulatory glucose profile in optimising glycaemic control in this population. Insulin-treated patients with type 1 and type 2 diabetes were recruited into a prospective, multicentre, 100-day study and randomised to control (n = 28) or intervention (n = 59) groups. The intervention group used ambulatory glucose profile, generated by continuous glucose monitoring, to assess daily glucose levels, whereas the controls relied on capillary glucose testing. Patients were reviewed at days 30 and 45 by the health care professional to adjust insulin therapy. Comparing first and last 2 weeks of the study, ambulatory glucose profile-monitored type 2 diabetes patients (n = 28) showed increased time in euglycaemia (mean ± standard deviation) by 1.4 ± 3.5 h/day (p = 0.0427) associated with reduction in HbA1c from 77 ± 15 to 67 ± 13 mmol/mol (p = 0.0002) without increased hypoglycaemia. Type 1 diabetes patients (n = 25) showed reduction in hypoglycaemia from 1.4 ± 1.7 to 0.8 ± 0.8 h/day (p = 0.0472) associated with a marginal HbA1c decrease from 75 ± 10 to 72 ± 8 mmol/mol (p = 0.0508). Largely similar findings were observed comparing intervention and control groups at end of study. In conclusion, ambulatory glucose profile helps glycaemic management in insulin-treated diabetes patients by increasing time spent in euglycaemia and decreasing HbA1c in type 2 diabetes patients, while reducing hypoglycaemia in type 1 diabetes patients.

Evaluation of Intradermal and Subcutaneous Infusion Set Performance Under 24-Hour Basal and Bolus Conditions

BACKGROUND

This study sought to assess the function and delivery reliability of intradermal (ID) infusion sets used with commercial insulin pumps.

METHOD

Healthy subjects (n = 43) were randomized to either ID or subcutaneous (SC) arms, and received basal/bolus placebo delivery for 24 hours. Subjects received 4 of 8 infusion set combinations (ID: microneedle design A or B, with 2 pump brands [Animas or MiniMed]; SC: Teflon Quickset or steel Rapid-D, Animas pump only, with or without overtaping) and were evaluated for pump occlusion alarms, fluid leakage, pain, and tissue tolerability. A novel algorithm was developed to determine flow consistency based on fluid pressure, and the duration and occurrence rate for periods of unalarmed but interrupted flow ("silent occlusions'") were compared.

RESULTS

ID delivery was successfully maintained over the 24-hour infusion period. The number of silent occlusions was lower for ID microneedle cannula design B than A (P < .01) and lower for Rapid-D SC device compared to Quick-set (P = .03). There was no significant difference in the number of occlusion alarms between the ID and SC devices with the Animas pump. However, the pumps tested with ID devices had significantly different alarm rates (MiniMed 29.5%, Animas 0%, P < .001). Leakage and tissue tolerability were comparable across devices.

CONCLUSION

The ID infusion set reliably delivered diluent for an extended 24-hour period in healthy subjects and was well tolerated. Silent occlusion flow interruptions could be detected in both ID and SC infusion sets using a proprietary algorithm. This algorithm is a promising method for quantitatively evaluating infusion set flow performance.

The role of continuous glucose monitoring in the care of children with type 1 diabetes

Continuous glucose monitoring (CGM), while a relatively new technology, has the potential to transform care for children with type 1 diabetes. Some, but not all studies, have shown that CGM can significantly improve hemoglobin A1c levels and reduce time spent in the hypoglycemic range in children, particularly when used as part of sensor-augmented pump (SAP) therapy. Despite the publication of recent clinical practice guidelines suggesting CGM be offered to all children 8 years of age or older who are likely to benefit, and studies showing that younger children can also benefit, this technology is not yet commonly used by children with type 1 diabetes. Effects of CGM are enhanced when used on a near-daily basis (a use-dependent effect) and with insulin pump therapy. Therefore, coordinated strategies are needed to help children and their families initiate and continue to use this resource for diabetes care. This review introduces CGM to pediatric endocrinologists who are not yet familiar with the finer details of this technology, summarizes current data showing the benefits and limitations of CGM use in children, reviews specific case examples demonstrating when CGM can be helpful, and shows the value of both retrospective and real-time CGM. It is hoped that this information leads to discussion of this technology in pediatric endocrinology clinics as an important next step in improving the care of children with type 1 diabetes.

Sleep Behaviors and Parent Functioning in Young Children With Type 1 Diabetes

This study evaluates sleep characteristics among young children with type 1 diabetes and associations with parent sleep and emotional functioning and diabetes care. Study participants included twenty-four parents of young children with type 1 diabetes (ages 2-5) enrolled in a pilot study of a randomized-controlled trial. Child sleep characteristics were within normal limits. However, increased child bedtime resistance and behavioral insomnia were related to greater parent stress, anxiety, and depression and use of an intensive insulin regimen. Type 1 diabetes management may impact child and parent sleep as well as parent emotional functioning. Implications for practice are presented.

A comparison of average daily risk range scores for young children with type 1 diabetes mellitus using continuous glucose monitoring and self-monitoring data

BACKGROUND

Young children with type 1 diabetes are vulnerable to glycemic excursion. Continuous glucose monitoring (CGM), combined with variability statistics, can offer a richer and more complete picture of glycemic variability in young children. In particular, we present data for the Average Daily Risk Range (ADRR) and compare ADRR scores calculated using CGM versus self-monitoring of blood glucose (SMBG) data for young children.

METHODS

CGM and SMBG data from 48 young children with type 1 diabetes (mean age, 5.1 years) were used to calculate two separate ADRR scores, using SMBG data (ADRRs) and CGM data (ADRRc), for each child. Additionally, we calculated mean amplitude of glycemic excursion (MAGE) scores for children to examine the concurrent validity of the ADRRs and ADRRc.

RESULTS

Young children's mean ADRRc score was significantly greater than their ADRRs score (55±12 and 46±11, respectively; P<0.001). In addition, 74% of the time the children's ADRRc score reflected greater variability risk than their ADRRs score. Examining the concurrent validity, children's ADRRc scores correlated positively with MAGE scores calculated using their CGM and SMBG data, whereas their ADRRs scores only correlated with MAGE scores calculated using SMBG.

CONCLUSIONS

ADRR scores generated for young children with type 1 diabetes demonstrate a high risk for glucose variability, but ADRR scores generated from CGM data may provide a more sensitive measure of variability than ADRR scores generated from SMBG. In young children with type 1 diabetes, ADRR scores calculated from CGM data may be superior to scores calculated from SMBG for measuring risk of excursion.

Closed-loop glucose control: psychological and behavioral considerations

Since 2000, the diabetes community has witnessed tremendous technological advances that have revolutionized diabetes management. Currently, closed-loop glucose control (CLC) systems, which link continuous subcutaneous insulin infusion and continuous glucose monitoring, are the newest, cutting edge technology aimed at reducing glycemic variability and improving daily management of diabetes. Although advances in knowledge and technology in the treatment of diabetes have improved exponentially, adherence to diabetes regimens remains complex and often difficult to predict. Human factors, such as patient perceptions and behavioral self-regulation, are central to adherence to prescribed regimens, as well as to adoption and utilization of diabetes technology, and they will continue to be crucial as diabetes management evolves. Thus, the aims of this article are three-fold: (1) to review psychological and behavioral factors that have influenced adoption and utilization of past technologies, (2) to examine three theoretical frameworks that may help in conceptualizing relevant patient factors in diabetes management, and (3) to propose patient-selection factors that will likely affect future CLC systems.

Assessing fear of hypoglycemia in children with Type 1 diabetes and their parents

This article summarizes the literature on fear of hypoglycemia in pediatric Type 1 diabetes and the assessment of this fear in both children with Type 1 diabetes and their parents. The most common instrument for assessing fear of hypoglycemia in this population is the children's and parent's versions of the Hypoglycemia Fear Survey (HFS), although studies using other assessment measures are also reviewed. Studies using this survey have identified variables contributing to fear of hypoglycemia in children with Type 1 diabetes and their parents, such as history of frequent or traumatic hypoglycemia, as well as trait anxiety. In addition to this summary of the literature, new data are presented supporting the reliability of hypoglycemic fear assessment in younger children and comparing fear of hypoglycemia in children in different age groups (6-18 years old) and their parents. Also reviewed are studies investigating the relationship between fear of hypoglycemia and diabetes control, which have yielded inconsistent results. Given the potential importance of fear of hypoglycemia in pediatric diabetes, there has been limited research in this area.

Use of continuous glucose monitoring systems in children with type 1 diabetes

Continuous glucose monitoring systems (CGMS) offer a recent technological solution to fear of hypoglycemia and reduction in hyperglycemia. With glucose readings every 5 minutes, and the alarm capabilities to signal rapid increases or decreases in blood glucose, they afford a sense of security for both children and parents. Although children and parents must continue to be vigilant in the treatment of diabetes, CGMS may effectively allow tight diabetes control with earlier detection of hypoglycemia onset. This article provides an overview of CGMS available at the time of publication; new generations of systems have been introduced annually with improvements in sensitivity and user friendliness.

Real-time continuous glucose monitoring system for treatment of diabetes: a systematic review

AIMS

  This study reviews the effect of real-time continuous glucose monitoring systems in diabetes management.

METHODS

  A systematic search was performed in PubMed/MEDLINE and EMBASE for randomized controlled trials comparing real-time continuous glucose monitoring systems with self-monitoring blood glucose or non-real-time continuous glucose monitoring systems.

RESULTS

  Nine randomized controlled trials were identified. Two studies used a device which is not on the market any more. In this review we focus on the other seven studies. Performing a meta-analysis was not possible because of extensive clinical heterogeneity. Six of seven studies showed some positive effect of real-time continuous glucose monitoring systems on HbA(1c) (HbA(1c) decrease 0.3-0.7% or 3-8 mmol/mol). In some studies, this effect only was shown in subgroups (compliant adult patients). However, the size of effect may be underestimated by better-than-average results in the control group, as self-monitoring blood glucose measurements are carried out more frequently than in usual clinical practice. Despite the goal of lowering HbA(1c) , no more severe hypoglycaemic episodes were seen, except in one study. In contrast, no positive effect was shown with the real-time continuous glucose monitoring system on hypoglycaemia, but randomized controlled trials were not designed or powered to investigate this issue. Time in different glucose strata was assessed only in some trials: two of them showed a significant but small increase in time in euglycaemia.

CONCLUSIONS

  Current evidence shows that the real-time continuous glucose monitoring system has a beneficial effect on glycaemic control in adult diabetes patients, without an increase in the incidence of hypoglycaemia. Studies in well-selected patient groups (pregnancy, history of severe hypoglycaemias, Type 2 diabetes) are lacking.

A glucose sensor protein for continuous glucose monitoring

In vivo continuous glucose monitoring has posed a significant challenge to glucose sensor development due to the lack of reliable techniques that are non- or at least minimally-invasive. In this proof-of-concept study, we demonstrated the development of a new glucose sensor protein, AcGFP1-GBPcys-mCherry, and an optical sensor assembly, capable of generating quantifiable FRET (fluorescence resonance energy transfer) signals for glucose monitoring. Our experimental data showed that the engineered glucose sensor protein can generate measurable FRET signals in response to glucose concentrations varying from 25 to 800 μM. The sensor developed based on this protein had a shelf-life of up to 3 weeks. The sensor response was devoid of interference from compounds like galactose, fructose, lactose, mannose, and mannitol when tested at physiologically significant concentrations of these compounds. This new glucose sensor protein can potentially be used to develop implantable glucose sensors for continuous glucose monitoring.
