Abstract
Diabetes mellitus is a prevalent chronic autoimmune disease with a high impact on global health, affecting millions of adults and resulting in significant morbidity and mortality. Achieving optimal blood glucose levels is crucial for diabetes management to prevent acute and long-term complications. Carbohydrate counting (CC) is widely used by patients with type 1 diabetes to adjust prandial insulin bolus doses based on estimated carbohydrate content, contributing to better glycemic control and improved quality of life. However, accurately estimating the carbohydrate content of meals remains challenging for patients, leading to errors in bolus insulin dosing. This review explores the current limitations and challenges in CC accuracy and emphasizes the importance of personalized educational programs to enhance patients' abilities in carbohydrate estimation. Existing tools for assessing patient learning outcomes in CC are discussed, highlighting the need for individualized approaches tailored to each patient's needs. A comprehensive review of the relevant literature was conducted to identify educational programs and assessment tools dedicated to training diabetes patients on carbohydrate counting. The research aims to provide insights into the benefits and limitations of existing tools and identifies future research directions to advance personalized CC training approaches. By adopting a personalized approach to CC education and assessment, healthcare professionals can empower patients to achieve better glycemic control and improve diabetes management. Moreover, this review identifies potential avenues for future research, paving the way for advancements in personalized CC training and assessment approaches and further enhancing diabetes management strategies.

Abstract
A sequential dearomatization/rearrangement reaction between quinazoline-derived azomethine imines and crotonate sulfonium salts has been developed to provide a series of three-dimensional cage-like molecules. The reaction involves two dearomatizations, two cyclizations, and two C-C bond and three C-N bond formations in one step. The new transformation has a broad substrate scope, does not require any added reagents, and proceeds under room temperature in a short time. A mechanistic rationale for the sequential dearomatization/rearrangement is also presented. Furthermore, the synthetic compounds are evaluated for their glucose control effect. Compounds 3aa and 3aj were found to be hyperglycemic, which might be lead compounds for treating hypoglycemia.

Abstract
BACKGROUND Nursing students in their final year of study will soon become responsible for the care and management of people with diabetes, and they need to be knowledgeable to provide adequate information. OBJECTIVES The aim of this study was to assess nursing students' knowledge regarding diabetes care and management. DESIGN A descriptive cross-sectional multicenter study. SETTINGS AND PARTICIPANTS A convenience sample of all nursing students' internship enrolled at three government universities in Saudi Arabia. METHODS 306 Saudi nursing students were surveyed with a self-administered questionnaire of the sociodemographic characteristics of the participants. The second part contained 23 multiple-choice questions of the Michigan Diabetes Knowledge Test. Data were collected from July to September 2022. RESULTS The overall percentage of correct responses was 49.28 %. There was a significant difference between sex, the university attended, attendance in courses related to diabetes, and diabetes management guidelines in any course and their knowledge about diabetes care and management (p = 0.024, 0.001, 0.036, and 0.038, respectively). There was a significant difference between nursing students' general knowledge and insulin use knowledge (p = 0.001). A multiple regression analysis revealed that the university attended was the only statistically significant factor (p = 0.001). CONCLUSION Nursing internship students are likely to be responsible for providing people with diabetes care and management once they qualify. Inappropriate knowledge negatively affects the care and management of people with diabetes. Information related to diabetic insulin therapy should be provided in more detail in the nursing curriculum.

Abstract
Recent advancements in hybrid closed-loop systems, also known as the artificial pancreas (AP), have been shown to optimize glucose control and reduce the self-management burdens for people living with type 1 diabetes (T1D). AP systems can adjust the basal infusion rates of insulin pumps, facilitated by real-time communication with continuous glucose monitoring. Deep reinforcement learning (DRL) has introduced new paradigms of basal insulin control algorithms. However, all the existing DRL-based AP controllers require extensive random online interactions between the agent and environment. While this can be validated in T1D simulators, it becomes impractical in real-world clinical settings. To this end, we propose an offline DRL framework that can develop and validate models for basal insulin control entirely offline. It comprises a DRL model based on the twin delayed deep deterministic policy gradient and behavior cloning, as well as off-policy evaluation (OPE) using fitted Q evaluation. We evaluated the proposed framework on an in silico dataset generated by the UVA/Padova T1D simulator, and the OhioT1DM dataset, a real clinical dataset. The performance on the in silico dataset shows that the offline DRL algorithm significantly increased time in range while reducing time below range and time above range for both adult and adolescent groups. Then, we used the OPE to estimate model performance on the clinical dataset, where a notable increase in policy values was observed for each subject. The results demonstrate that the proposed framework is a viable and safe method for improving personalized basal insulin control in T1D.

Abstract
OBJECTIVE The purpose of this study was to evaluate the performance of algorithms for identifying cases of severe hypoglycemia in Japanese hospital administrative data. METHODS This was a multicenter, retrospective, observational study conducted at 3 acute-care hospitals in Japan. The study population included patients aged ≥18 years with diabetes who had an outpatient visit or hospital admission for possible hypoglycemia. Possible cases of severe hypoglycemia were identified using health insurance claims data and Diagnosis Procedure Combination data. Sixty-one algorithms using combinations of diagnostic codes and prescription of high concentration (≥20% mass/volume) injectable glucose were used to define severe hypoglycemia. Independent manual chart reviews by 2 physicians at each hospital were used as the reference standard. Algorithm validity was evaluated using standard performance metrics. RESULTS In total, 336 possible cases of severe hypoglycemia were identified, and 260 were consecutively sampled for validation. The best performing algorithms included 6 algorithms that had sensitivity ≥0.75, and 6 algorithms that had positive predictive values ≥0.75 with sensitivity ≥0.30. The best-performing algorithm with sensitivity ≥0.75 included any diagnoses for possible hypoglycemia or prescription of high-concentration glucose but excluded suspected diagnoses (sensitivity: 0.986 [95% confidence interval 0.959-1.013]; positive predictive value: 0.345 [0.280-0.410]). Restricting the algorithm definition to those with both a diagnosis of possible hypoglycemia and a prescription of high-concentration glucose improved the performance of the algorithm to correctly classify cases as severe hypoglycemia but lowered sensitivity (sensitivity: 0.375 [0.263-0.487]; positive predictive value: 0.771 [0.632-0.911]). CONCLUSION The case-identifying algorithms in this study showed moderate positive predictive value and sensitivity for identification of severe hypoglycemia in Japanese healthcare data and can be employed by future pharmacoepidemiological studies using Japanese hospital administrative databases.

Abstract
Hypoglycemia, a common consequence of diabetes treatment, is associated with severe morbidity and mortality and has become a major barrier to intensifying antidiabetic therapy. Severe hypoglycemia, defined as abnormally low blood glucose requiring the assistance of another person, is associated with seizures and comas, but even mild hypoglycemia can cause troubling symptoms such as anxiety, palpitations, and confusion. Dementia generally refers to the loss of memory, language, problem-solving, and other cognitive functions, which can interfere with daily life, and there is growing evidence that diabetes is associated with an increased risk of both vascular and non-vascular dementia. Neuroglycopenia resulting from a hypoglycemic episode in diabetic patients can lead to the degeneration of brain cells, with a resultant cognitive decline, leading to dementia. In light of new evidence, a deeper understating of the relationship between hypoglycemia and dementia can help to inform and guide preventative strategies. In this review, we discuss the epidemiology of dementia among patients with diabetes, and the emerging mechanisms thought to underlie the association between hypoglycemia and dementia. Furthermore, we discuss the risks of various pharmacological therapies, emerging therapies to combat hypoglycemia-induced dementia, as well as risk minimization strategies.

Abstract
Diabetes mellitus is recognized as a risk factor for sarcopenia. Luseogliflozin, a selective sodium-glucose cotransporter 2 (SGLT2) inhibitor, reduces inflammation and oxidative stress by improving hyperglycemia, subsequently improving hepatosteatosis or kidney dysfunction. However, the effects of SGLT2 inhibitor on the regulation of skeletal muscle mass or function in hyperglycemia are still unknown. In this study, we investigated the effects of luseogliflozin-mediated attenuation of hyperglycemia on the prevention of muscle atrophy. Twenty-four male Sprague-Dawley rats were randomly divided into four groups: control, control with SGLT2 inhibitor treatment, hyperglycemia, and hyperglycemia with SGLT2 inhibitor treatment. The hyperglycemic rodent model was established using a single injection of streptozotocin, a compound with preferential toxicity toward pancreatic beta cells. Muscle atrophy in streptozotocin-induced hyperglycemic model rats was inhibited by the suppression of hyperglycemia using luseogliflozin, which consequently suppressed hyperglycemia-mediated increase in the levels of advanced glycation end products (AGEs) and activated the protein degradation pathway in muscle cells. Treatment with luseogliflozin can restore the hyperglycemia-induced loss in the muscle mass to some degree partly through the inhibition of AGEs-induced or homeostatic disruption of mitochondria-induced activation of muscle degradation.

Abstract
BACKGROUND Nasal glucagon (NG) 3 mg is approved in Japan to treat hypoglycemia in pediatric patients with diabetes, but an NG clinical study has not been performed in Japanese children because of practical and ethical concerns. OBJECTIVE The aim of this study is to support the dose rationale for NG 3 mg in Japanese pediatric patients with diabetes using modeling and simulation. METHODS We used a pharmacokinetic/pharmacodynamic bridging approach to extrapolate the available clinical data to Japanese pediatric patients. Population pharmacokinetic/pharmacodynamic modeling was performed using data from seven clinical studies, including five studies in non-Japanese adults, one study in Japanese adults, and one study in non-Japanese pediatric patients. Simulation was then used to estimate glucagon exposure and glucose response after NG 3-mg administration for three age categories of Japanese pediatric patients: 4 to < 8, 8 to < 12, and 12 to < 18 years. Treatment success was defined as an increase in blood glucose to ≥ 70 or ≥ 20 mg/dL from nadir within 30 min after administration of NG 3 mg. Safety was assessed in relation to the predicted maximum glucagon concentration of NG 3 mg using NG clinical trial data and published data on intravenous and intramuscular glucagon. RESULTS The data showed a rapid and robust glucose response following NG 3 mg in Japanese and non-Japanese adults and non-Japanese pediatric patients, with some differences in glucagon exposure observed across studies. The pharmacokinetic/pharmacodynamic model described the observed clinical data well, and simulations indicated that > 99% of hypoglycemic Japanese pediatric patients in all three age groups would achieve treatment success. Predicted glucose responses to NG 3 mg in Japanese pediatric patients were comparable to those of intramuscular glucagon. Maximum concentration was not associated with the occurrence and severity of common adverse events (nausea, vomiting, and headache) in NG clinical studies. Furthermore, the predicted maximum concentration in Japanese pediatric patients, despite being higher than the observed maximum concentration in NG clinical studies, was substantially lower than the observed maximum concentration of 1 mg of intravenous glucagon, without serious safety issues. CONCLUSIONS This analysis suggests NG 3 mg has robust efficacy without serious safety concerns in Japanese pediatric patients with diabetes.

Abstract
Diabetes increases the risk of Alzheimer's disease (AD). We investigated the impact of glucose concentrations on the β-amyloid (Aβ)-induced alteration of mitochondrial/cellular energetics in primary human brain microvascular endothelial cells (HBMECs). HBMECs were grown and passaged in media containing 15 mmol/l glucose (normal) based on which the glucose levels in the media were designated as high (25 mmol/L) or low (5 mmol/L). HBMECs were treated with Aβ (1-42) (5 µmol/l) or a scrambled peptide for 24 h and mitochondrial respiratory parameters were measured using Seahorse Mito Stress Test. Aβ (1-42) decreased the mitochondrial ATP production at normal glucose levels and decreased spare respiratory capacity at high glucose levels. Aβ (1-42) diminished all mitochondrial respiratory parameters markedly at low glucose levels that were not completely recovered by restoring normal glucose levels in the media. The addition of mannitol (10 mmol/l) to low and normal glucose-containing media altered the Aβ (1-42)-induced bioenergetic defects. Even at normal glucose levels, pre-senescent HMBECs (passage 15) displayed greater Aβ (1-42)-induced mitochondrial respiratory impairments than young cells (passages 7-9). Thus, hypoglycemia, osmolarity changes, and senescence are stronger instigators of Aβ (1-42)-induced mitochondrial respiration and energetics in HBMECs and contributors to diabetes-related increased AD risk than hyperglycemia.

PLoS One 2022; 17:e0275786. [PMID: 36318542 PMCID: PMC9624414 DOI: 10.1371/journal.pone.0275786] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Accepted: 09/22/2022] [Indexed: 11/07/2022] Open
Abstract
BACKGROUND Hypoglycemia is an urgent, life-threatening condition that requires prompt recognition and treatment for diabetes mellitus patients to prevent organ and brain damage. Hypoglycemia is one of the most important complications of diabetes mellitus patients around the globe. Hypoglycemia may increase vascular events and even death, in addition to other possible detrimental effects. In spite of the absence of other risk factors, patients receiving intensive insulin therapy are more likely to experience hypoglycemia. To reduce the risk of hypoglycemia and calculate the combined prevalence of hypoglycemia prevention practices among diabetes mellitus patients, recognition of hypoglycemia is critical. OBJECTIVE The main aim of this review was to evaluate the available data on Ethiopian diabetes mellitus patients' practices for preventing hypoglycemia and related factors. METHODS AND MATERIALS This review was searched using PubMed, the Cochrane Library, Google, Google Scholar, and the Web of Sciences. Microsoft Excel was used to extract the data. All statistical analyses were done using STATA Version 14 software with a random-effects model. The funnel plot and heterogeneity of the studies were checked. Subgroup analysis was done with the study area and authors' names. RESULTS In this systematic review, 12 studies totaling 3,639 participants were included. The estimated overall practice for preventing hypoglycemia among diabetic patients in Ethiopia were 48.33% (95% CI (28.21%, 68.46%, I2 = 99.7%, p ≤ 0.001). According to the subgroup analysis based on region, the highest estimated prevalence of the prevention practice of hypoglycemia among diabetes patients in Addis Ababa was 90%, followed by SNNRP at 76.18% and in the Amhara region at 68.31% respectively. The least prevalent was observed in the Oromia region 6.10%. In this meta-analysis, diagnoses with type II diabetes (AOR = 2.53, 95%CI: 1.05, 4.04), duration (AOR = 5.49, 95%CI:3.27,7.70), taking insulin for a long time(AOR = 4.31,95%CI:2.60,6.02), having good prevention knowledge (AOR = 2.89, 95%CI: 1.15,4.23), and occupation (AOR = 4.17, 95%CI: 2.20, 6.15) were significantly associated with hypoglycemia prevention practice. CONCLUSIONS This systematic review revealed that diabetic patients in Ethiopia had poor hypoglycemia prevention practices. Being an employee, taking insulin for a long time, having a good prevention practice, and having a type of diabetes mellitus were strongly correlated with practicing hypoglycemia prevention. This review implied the subsequent need for educational interventions for an individualized patient.

Abstract
AIMS To determine safety of intranasal insulin (INI) in MemAID trial participants with diabetes treated with systemic insulins. MATERIALS AND METHODS This randomized, double-blinded trial consisted of 24-week INI or placebo treatment once daily and 24-week follow-up. Safety outcomes were: 1) Short-term effects on glycemic variability, hypoglycemic episodes on continuous glucose monitoring (CGM) at baseline and on-treatment. 2) Long-term effects on glucose metabolism and weight on INI/placebo treatment and post-treatment follow-up. Of 86 screened subjects, 14 were randomized, 9 (5 INI, 4 Placebo) completed CGM at baseline and on-treatment, and 5 (2 INI, 3 Placebo) completed treatment and follow-up. RESULTS INI was safe and was not associated with serious adverse events, hypoglycemic episodes or weight gain. INI administration did not acutely affect capillary glucose. Glycemic variability on CGM decreased with INI, compared to baseline. On INI treatment, there was a long-term trend toward lower HbA1c, plasma glucose and insulin. No interactions with subcutaneous insulins were observed. CONCLUSIONS INI is safe in older people with diabetes treated with systemic insulins, and it is not associated with adverse events, hypoglycemia or weight gain. Future studies are needed to determine whether INI administration can reduce glycemic variability, improve insulin sensitivity and thus potentially lessen diabetes burden in this population.

Abstract
The current study aimed to explore active metabolites of locally recognized and
high yielding cultivar cluster bean (BR-99) with a wide range of adaptability
having antioxidant, antidiabetic, antimicrobial, and cytotoxic potential. Six
solvents were used (crude methanol, n-hexane, chloroform, ethyl acetate,
butanol, and aqueous) with escalating polarity for colorimetric determination of
antioxidants such as total phenolic contents (TPC), total flavonoid contents
(TFC), and free radical scavenging activity (FRSA) by DPPH (2,
2-diphenyl-1-picrylhydrazyl) assay. Moreover, an antidiabetic and anticancer
study was conducted by α-amylase inhibition and MTT (3-(4,
5-dimethyl-2-thiazolyl)-2, 5-diphenyl-tetrazolium bromide) assay. Biological
investigations were carried out against the most commonly found infectious
microbial strains. The significant results (P ≤ .001) of each activity were seen
among six tested solvent extracts. The ethyl acetate and methanol extract have
more antioxidant potential with the highest TPC (16.38 ± .13 mg GAE/g) and TFC
(8.15 ± .24 mg CE/g), respectively. Similarly, methanol extract presented the
highest free radical scavenging activity (46.31 ± .91%), followed by ethyl
acetate, butanol, chloroform, aqueous, and n-hexane extract. However, the
maximum α-amylase inhibition (62.54 ± 1.47%) and anticancer activity against
human lung cancer cells were congregated (78.31 ± 1.46%) in butanol and
chloroform, respectively. A positive correlation was seen between TPC with TFC
(R2= .8356), FRSA
(R2= .8381), and anti-diabetic activity
(R2= .8082), which highlights the phenolic
contents as strong anti-oxidant agents especially flavonoids. Each extract of
cluster bean (BR-99) showed significant antimicrobial activities for all tested
bacterial strains except B. cereus and E.
coli. The profound results of maximum antibacterial activity were
witnessed by chloroform extract while ethyl acetate extracts showed great
antifungal potential against all tested fungal strains. The HPLC quantitative
analysis results of cluster bean (BR-99) revealed the presence of active
phytochemicals such as gallic acid, HB acid, vanillic acid, kaempferol, sinapic
acid, ferulic acid, salicylic acid, coumarins, quercetin, rutin, p-coumaric
acid, and catechin, and the variation in both phytochemical and biological
spectrums envisioned the cluster bean (BR-99) used in future as a cheap, safer,
and potent source of bioactive drugs.

Abstract
INTRODUCTION Hypoglycaemia is a frequent adverse event and major barrier for achieving optimal blood glucose levels in people with type 1 or type 2 diabetes using insulin. The Hypo-RESOLVE (Hypoglycaemia-Redefining SOLutions for better liVEs) consortium aims to further our understanding of the day-to-day impact of hypoglycaemia. The Hypo-METRICS (Hypoglycaemia-MEasurement, ThResholds and ImpaCtS) application (app) is a novel app for smartphones. This app is developed as part of the Hypo-RESOLVE project, using ecological momentary assessment methods that will minimise recall bias and allow for robust investigation of the day-to-day impact of hypoglycaemia. In this paper, the development and planned psychometric analyses of the app are described. METHODS AND ANALYSIS The three phases of development of the Hypo-METRICS app are: (1) establish a working group-comprising diabetologists, psychologists and people with diabetes-to define the problem and identify relevant areas of daily functioning; (2) develop app items, with user-testing, and implement into the app platform; and (3) plan a large-scale, multicountry study including interviews with users and psychometric validation. The app includes 7 modules (29 unique items) assessing: self-report of hypoglycaemic episodes (during the day and night, respectively), sleep quality, well-being/cognitive function, social interactions, fear of hypoglycaemia/hyperglycaemia and work/productivity. The app is designed for use within three fixed time intervals per day (morning, afternoon and evening). The first version was released mid-2020 for use (in conjunction with continuous glucose monitoring and activity tracking) in the Hypo-METRICS study; an international observational longitudinal study. As part of this study, semistructured user-experience interviews and psychometric analyses will be conducted. ETHICS AND DISSEMINATION Use of the novel Hypo-METRICS app in a multicountry clinical study has received ethical approval in each of the five countries involved (Oxford B Research Ethics Committee, CMO Region Arnhem-Nijmegen, Ethikkommission der Medizinischen Universität Graz, Videnskabsetisk Komite for Region Hovedstaden and the Comite Die Protection Des Personnes SUD Mediterranne IV). The results from the study will be published in peer review journals and presented at national and international conferences. TRIAL REGISTRATION NUMBER NCT04304963.

Conversations and Reactions Around Severe Hypoglycemia (CRASH) global survey of people with type-1 diabetes or insulin-treated type-2 diabetes and caregivers: findings from the French cohort. ANNALES D'ENDOCRINOLOGIE 2021; 83:16-26. [PMID: 34871601 DOI: 10.1016/j.ando.2021.11.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 11/10/2021] [Accepted: 11/15/2021] [Indexed: 11/16/2022]
Abstract
AIM The objective of the CRASH (Conversations and Reactions Around Severe Hypoglycemia) survey was to further our understanding of the characteristics, experience, behavior and conversations with healthcare professionals (HCPs) of persons with diabetes (PWD) receiving insulin, and of their caregivers (CGs), concerning hypoglycemia requiring external assistance (severe hypoglycemic events [SHEs]). METHODS CRASH was an online cross-sectional survey conducted across eight countries. The PWDs with self-reported type 1 (T1D) or insulin-treated type 2 (T2D) diabetes were aged ≥18 years and had experienced one or more SHEs in past the 3 years; CGs were non-medical professionals aged ≥18 years, caring for a PWD meeting all the above criteria except for PWD age (≥4 rather than ≥18 years). The present report is a descriptive analysis of data from France. RESULTS Among PWDs who had ever discussed SHEs with an HCP, 38.9% of T1D PWDs and 50.0% of T2D PWDs reported that SHEs were discussed at every consultation; 26.3% and 8.8% respectively had not discussed the most recent SHE with an HCP. 35.7% of T1D PWDs and 53.8% of T2D PWDs reported that glucagon was not available to them at the time of their most recent SHE. Only 16.9% of T1D PWDs and 6.5% of T2D PWDs who had discussed their most recent SHE with an HCP reported that the HCP recommended obtaining a glucagon kit or asked them to confirm that they already had one. High proportions of PWDs and CGs reported that the most recent SHE had made them feel unprepared, scared and helpless and had affected mood, emotional state and activities. CONCLUSION CRASH survey data from France identify a need for greater discussion about SHEs between HCPs and PWDs and their CGs, and reveal gaps in the diabetes education of PWDs and CGs.

Abstract
Background Iatrogenic hypoglycemia is a common occurrence among hospitalized patients and is associated with poor clinical outcomes and increased mortality. Clinical decision support systems can be used to reduce the incidence of this potentially avoidable adverse event. Objective This study aims to determine the desired features and functionality of a real-time informatics alert to prevent iatrogenic hypoglycemia in a hospital setting. Methods Using the Agency for Healthcare Research and Quality Five Rights of Effective Clinical Decision Support Framework, we conducted a mixed methods study using an electronic survey and focus group sessions of hospital-based providers. The goal was to elicit stakeholder input to inform the future development of a real-time informatics alert to target iatrogenic hypoglycemia. In addition to perceptions about the importance of the problem and existing barriers, we sought input regarding the content, format, channel, timing, and recipient for the alert (ie, the Five Rights). Thematic analysis of focus group sessions was conducted using deductive and inductive approaches. Results A 21-item electronic survey was completed by 102 inpatient-based providers, followed by 2 focus group sessions (6 providers per session). Respondents universally agreed or strongly agreed that inpatient iatrogenic hypoglycemia is an important problem that can be addressed with an informatics alert. Stakeholders expressed a preference for an alert that is nonintrusive, accurate, communicated in near real time to the ordering provider, and provides actionable treatment recommendations. Several electronic medical record tools, including alert indicators in the patient header, glucose management report, and laboratory results section, were deemed acceptable formats for consideration. Concerns regarding alert fatigue were prevalent among both survey respondents and focus group participants. Conclusions The design preferences identified in this study will provide the framework needed for an informatics team to develop a prototype alert for pilot testing and evaluation. This alert will help meet the needs of hospital-based clinicians caring for patients with diabetes who are at a high risk of treatment-related hypoglycemia.

Value Health Reg Issues 2021; 28:82-89. [PMID: 34839111 DOI: 10.1016/j.vhri.2021.04.006] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2020] [Revised: 03/26/2021] [Accepted: 04/20/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVES To estimate the direct medical cost of type 2 diabetes mellitus (T2DM) and its complications in the Indonesian population from a payer perspective using a prevalence-based approach. METHODS The direct medical costs in 2016 were estimated using the database of Indonesia's National Health Insurance, known as Jaminan Kesehatan Nasional, which included diagnosis-related group costs and unbundled costs for patients accessing advanced care. The study population included people aged 30 years or older having a diagnosis of T2DM. T2DM and its related complications were identified using the International Classification of Diseases, 10th Revision, code. Hypoglycemia and all complications listed in the Diabetes Severity Complications Index were included. Descriptive analysis was conducted. Costs were converted to 2016 US dollar equivalent. RESULTS Of the 18.9 million Jaminan Kesehatan Nasional members who accessed secondary and tertiary care, 812 204 (4%) were identified with T2DM, of which 57% had complications. The most common complication was cardiovascular diseases (24%). The total direct medical cost was US $576 million, with 56% spent on hospitalization, 38% on specialist visits, 4% on unbundled non-diabetes-related medication, and 2% on unbundled anti-hyperglycemic medications. Approximately 74% of the total costs was used for the management of people with complications. People with complications (US $930/person/year ± US $1480/person/year) incurred twice the cost of those without complications (US $421/person/year ± US $745/person/year). CONCLUSION The direct medical cost for management of people with T2DM in Indonesia was high. Early diagnosis and optimal management of T2DM to prevent complications may reduce the costly sequelae and have a possibility of cost savings.

Tahara A. SGLT2 inhibitor ipragliflozin exerts antihyperglycemic effects via the blood glucose-dependent increase in urinary glucose excretion in type 2 diabetic mice. Eur J Pharmacol 2021; 910:174486.

Abstract
This study investigated the antihyperglycemic effects of the sodium-glucose cotransporter 2 (SGLT2) inhibitor ipragliflozin via the blood glucose-dependent increase in urinary glucose excretion in KK/Ay type 2 diabetic mice. In oral glucose tolerance tests (glucose load: 1, 2, or 4 g/kg) in 24-h-fasted mice, blood glucose levels increased in a glucose-loading dose-dependent manner. Oral administration of ipragliflozin (1 mg/kg) significantly inhibited the increase in blood glucose concomitant with urinary glucose excretion. To investigate the effects of ipragliflozin under low blood glucose conditions, blood glucose level and urinary glucose excretion were examined under fasting conditions in diabetic mice that had prefasted for 0, 6, 12, 18, or 24 h. Ipragliflozin significantly lowered blood glucose levels in mice that had prefasted for 0, 6, or 12 h, but not 18 h or more. Blood glucose level was well correlated with ipragliflozin-induced antihyperglycemic and urinary glucose excretion effects, suggesting that these effects occur in a blood glucose-dependent manner. Thus, in a hyperglycemic state, ipragliflozin exerts a potent antihyperglycemic effect and marked increases in urinary glucose excretion; however, in a non-hyperglycemic or hypoglycemic state, the hypoglycemic effect is weak. Ipragliflozin may therefore be a useful antidiabetic agent for normalizing daily blood glucose fluctuations in type 2 diabetes.

Abstract
BACKGROUND Detailed evaluations of hypoglycemia and associated indices based on continuous glucose monitoring (CGM) are limited in patients with diabetes of the exocrine pancreas. Our study sought to evaluate the frequency and pattern of hypoglycemic events and to investigate hypoglycemia-specific indices in this population. METHODS This was a cross-sectional study comprising 83 participants with diabetes of the exocrine pancreas. CGM and self-monitoring of blood glucose (SMBG) were performed on all participants for a minimum period of 72 hours. The frequency and pattern of hypoglycemic events, as well as hypoglycemia-related indices, were evaluated. RESULTS Hypoglycemia was detected in 90.4% of patients using CGM and 38.5% of patients using SMBG. Nocturnal hypoglycemic events were more frequent (1.9 episodes/patient) and prolonged (142 minutes) compared with day-time events (1.1 episodes/patient; 82.8 minutes, P < 0.05). The mean low blood glucose index was 2.1, and glycemic risk assessment diabetes equation hypoglycemia was 9.1%. The mean time spent below (TSB) <70 mg/dL was 9.2%, and TSB <54 mg/dL was 3.7%. The mean area under curve (AUC) <70 mg/dL was 1.7 ± 2.5 mg/dL/hour and AUC <54 mg/dL was 0.6 ± 1.3 mg/dL/hour. All of the CGM-derived hypoglycemic indices were significantly more deranged at night compared with during the day (P < 0.05). CONCLUSION Patients with diabetes of the exocrine pancreas have a high frequency of hypoglycemic episodes that are predominantly nocturnal. CGM is superior to SMBG in the detection of nocturnal and asymptomatic hypoglycemic episodes. CGM-derived hypoglycemic indices are beneficial in estimating the risk of hypoglycemia.

Abstract
AIM To summarize and critically appraise the recent qualitative evidence regarding the impact of hypoglycaemia on the quality of life of family members of adults with type 1 or type 2 diabetes. METHODS Four databases were searched systematically (MEDLINE, PsycINFO, CINAHL and Cochrane Library), and results were screened for eligibility. Article quality was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research. Data were extracted, coded and analysed using thematic analysis. The systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and Enhancing transparency in reporting of qualitative research (ENTREQ) guidelines. RESULTS Eight qualitative studies were included in the final review. The majority of participants were partners or spouses of adults with type 1 diabetes. Thematic synthesis resulted in six analytical themes: 'Hypoglycaemia alters everyday life, reducing freedoms and increasing disruptions', 'Hypoglycaemia has an adverse impact on sleep', 'Hypoglycaemia negatively changes the relationship with the person with diabetes', 'Hypoglycaemia negatively impacts emotional well-being', 'The detection, prevention, and treatment of hypoglycaemia consumes time and energy' and 'Family members have unmet needs for informational and emotional support regarding hypoglycaemia'. Across the six analytical themes, family members described how hypoglycaemia has a severe negative impact on different aspects of their lives, including daily living, personal relationships and emotional well-being. CONCLUSIONS Family members experience the impact of hypoglycaemia as a major recurrent challenge in their lives. The unmet needs of family members need further attention in research and clinical practice.

Fasting biochemical hypoglycemia and related-factors in non-diabetic population: Kanagawa Investigation of Total Check-up Data from National Database-8. World J Diabetes 2021; 12:1131-1140. [PMID: 34326960 PMCID: PMC8311474 DOI: 10.4239/wjd.v12.i7.1131] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 04/28/2021] [Accepted: 06/22/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND In healthy people, the lowest daily blood glucose concentration is usually observed in the early morning, after overnight fasting. However, the clinical relevance and the prevalence of fasting biochemical hypoglycemia (FBH) are poorly understood in people who do not have diabetes, although the clinical implications of such hypoglycemia have been extensively studied in patients with diabetes. FBH can be influenced by many factors, including age, sex, body mass, smoking, alcohol drinking, exercise levels, medications, and eating behaviors, such as breakfast skipping and late-night eating.
AIM To determine the prevalence of FBH and investigated its association with potential risk factors in a population without diabetes.
METHODS Clinical parameters and lifestyle-related factors were assessed in a cross-sectional study of 695613 people aged 40-74 years who had undergone a health check-up (390282 men and 305331 women). FBH was defined as fasting plasma glucose < 70 mg/dL (3.9 mmol/L) after overnight fasting, regardless of any symptoms. The absence of diabetes was defined as HbA1c < 6.5%, fasting plasma glucose < 126 mg/dL (7.0 mmol/L), and no pharmacotherapy for diabetes. Multivariate logistic regression analysis, with adjustment for confounding factors, was used to identify associations.
RESULTS FBH was present in 1842 participants (0.26%). There were significantly more women in the FBH group (59.1%) than in the non-FBH group (43.9%). Values of most of the clinical parameters, but not age, were significantly lower in the FBH group than in the non-FBH group. Logistic regression analysis showed that a body mass index of ≤ 20.9 kg/m2 (reference: 21-22.9 kg/m2) and current smoking were significantly associated with FBH, and this was not altered by adjustment for age, sex, and pharmacotherapy for hypertension or dyslipidemia. Female sex was associated with FBH. When the data were analyzed according to sex, men in their 60s or 70s appeared more likely to experience FBH compared with their 40s, whereas men in their 50s and women aged ≥ 50 years appeared less likely to experience FBH. The relationships of FBH with other factors including alcohol drinking and pharmacotherapies for hypertension and dyslipidemia also differed between men and women.
CONCLUSION FBH occurs even in non-diabetic people, albeit at a very low frequency. FBH is robustly associated with low body mass and smoking, and its relationship with lifestyle factors varies according to sex.

Abstract
PURPOSE To investigate whether diabetes knowledge and health literacy impact glycemic control after 1 year of intermittently scanned continuous glucose monitoring (isCGM) in people with type 1 diabetes ≥ 16 years. METHODS In this prospective real-world cohort study, we assessed diabetes knowledge using a new 10-item questionnaire [Patient Education and Knowledge (PEAK)] and health literacy using the validated 6-item Newest-Vital Sign-D (NVS-D) questionnaire. Primary endpoint was association between PEAK score and change in hemoglobin A1c (HbA1c). Secondary endpoints were link between NVS-D score and change in HbA1c and that between time spent in/above/below range and PEAK/NVS-D scores. RESULTS 851 subjects were consecutively recruited between July 2016 and July 2018. Median PEAK score was 8 (range: 0-10), and median NVS-D score was 6 (range 0-6). HbA1c evolved from 7.9% (7.8%-8.0%), 63 (62-64) mmol/mol, at start to 7.7% (7.6%-7.7%), 61 (60-61) mmol/mol (P < 0.001), at 6 months and to 7.8% (7.7%-7.9%), 62 (61-63) mmol/mol, at 12 months (P < 0.001). HbA1c only improved in subgroups with higher scores [PEAK subgroups with score 7-8 (P = 0.005) and 9-10 (P < 0.001) and NVS-D score 4-6 (P < 0.001)]. At 12 months, time spent below 70 mg/dL was reduced by 15% (P < 0.001), and time spent below 54 mg/dL was reduced by 14% (P < 0.001), irrespective of PEAK/NVS-D score. Multiple linear regression analysis demonstrated an association of PEAK score, scan frequency, and baseline HbA1c with evolutions in time in range and time in hyperglycemia. CONCLUSIONS isCGM reduced time in hypoglycemia, and HbA1c evolved favorably. Our findings suggest that diabetes and health literacy affect glucometrics, emphasizing the importance of education.

Abstract
The aim of this review study was to assess the past significant events on diabetes mellitus, transformations that took place over the years in the medical records of treatment, countries involved, and the researchers who brought about the revolutions. This study used the content analysis to report the existence of diabetes mellitus and the treatments provided by researchers to control it. The focus was mainly on three main types of diabetes (type 1, type 2, and type 3 diabetes). Ethical consideration has also helped to boost diabetic studies globally. The research has a history path from pharmaceuticals of organic-based drugs to metal-based drugs with their nanoparticles in addition to the impacts of nanomedicine, biosensors, and telemedicine. Ongoing and future studies in alternative medicine such as vanadium nanoparticles (metal nanoparticles) are promising.

Abstract
The fastest growing demographic in the U.S. at the present time is those aged 65 years and older. Accompanying advancing age are a myriad of physiological changes in which reserve capacity is diminished and homeostatic control attenuates. One facet of homeostatic control lost with advancing age is glucose tolerance. Nowhere is this more accentuated than in the high proportion of older Americans who are diabetic. Coupled with advancing age, diabetes predisposes affected subjects to the onset and progression of cardiovascular disease (CVD). In the treatment of type 2 diabetes, hypoglycemic episodes are a frequent clinical manifestation, which often result in more severe pathological outcomes compared to those observed in cases of insulin resistance, including premature appearance of biomarkers of senescence. Unfortunately, molecular mechanisms of hypoglycemia remain unclear and the subject of much debate. In this review, the molecular basis of the aging vasculature (endothelium) and how glycemic flux drives the appearance of cardiovascular lesions and injury are discussed. Further, we review the potential role of the serum response factor (SRF) in driving glycemic flux-related cellular signaling through its association with various proteins.

Abstract
Massive efforts have been devoted to insulin delivery for diabetes care. Achieving a long-term tight-regulated blood glucose level with a low risk of hypoglycemia remains a great challenge. In this study we propose a novel strategy to efficiently regulate insulin action after insulin is injected or released into patient body aiming to achieve better glycemic control, which is achieved by the administration of insulin-conjugated magnetic nanoparticles (MNPs-Ins). We show that the locomotion of MNPs-Ins can be controlled to reach a target site on an in vitro microfluidic platform, which may open a way to modulate the physiological effect of insulin in a remote-control manner. Most importantly, the in vivo blood glucose regulation of the MNPs-Ins was performed on diabetic mice to understand the glycemic control performance. The results showed that the MNPs-Ins can achieve a better glycemic control with longer effective drug duration while not causing hypoglycemia and a magnetic-modulated hypoglycemic dynamics. Moreover, the in vivo histochemistry experiments confirmed the good biocompatibility of MNPs-Ins. Along with our on-going research on the possibility of the recycle and reuse of the MNPs-Ins, the finding presented in this paper may manifest a fascinating potential in insulin delivery in the near future.

Abstract
We examined the relationship between two malleable risk factors, depressive symptoms and fear of hypoglycemia, in children and adolescents with Type 1 diabetes and their relationship to two important outcomes, adherence behaviors and metabolic control. To assess this relationship, we used a multidimensional measure of adherence, assessing frequency of both blood glucose monitoring and healthy behaviors including diet and exercise. We predicted that higher levels of depressive symptoms and higher levels of fear of hypoglycemia would be associated with worse metabolic control as mediated by poor adherence. Eighty-three children and adolescents ages 8 to 20 (M = 13.87, SD 3.21) were recruited from March 2014 to October 2014 at an outpatient diabetes clinic in a moderately sized Southeastern city within the USA. Nested models were evaluated using structural equation modeling. Adherence significantly mediated the relationship between depressive symptoms and metabolic control with more depressive symptoms leading to worse metabolic control. Adherence marginally mediated the relationship between fear of hypoglycemia and metabolic control; however, less fear of hypoglycemia was associated with worse metabolic control. In a combined model, adherence continued to significantly mediate the relationship between depressive symptoms and metabolic control, while also independently significantly mediating the relationship between fear of hypoglycemia and metabolic control. This finding was also contrary to the predicted relationship with less fear of hypoglycemia leading to worse metabolic control. The results indicate that youth with fewer depressive symptoms and more fear of hypoglycemia had better adherence to their treatment regimen, which was associated with better metabolic control. The results of this study highlight the importance of screening for depression and fear of hypoglycemia during routine clinic visits to optimize adherence and metabolic control.

Abstract
Cardiovascular disease is a leading cause of death in diabetic patients. Hyperglycaemia and iatrogenic hypoglycaemia exacerbate several pathogenic mechanisms underlying hypertension and heart diseases. Carnitine is a potent endogenous antioxidant and cellular fatty acid transporter for antioxidative stress and energy production in the cardiovascular system. The current study aimed to find the role of carnitine in the regulation of hypoglycaemia-induced hypertension and cardiac hypertrophy. Male rats received insulin glargine (InG) to induce hypoglycaemia followed by D-carnitine or acetyl-L-carnitine for carnitine depletion or carnitine supplementation, respectively. The obtained results showed that carnitine deficiency provoked hypoglycaemia-induced hypertension. Mean arterial pressure was elevated from 78.16 ± 11.4 to 100 ± 5.11 mm Hg in InG treated group, and from 78.2 ± 8.5 to 123.4 ± 28.2 mm Hg in InG + D-carnitine treated group. Acetyl-L-carnitine resisted the elevation in blood pressure in all hypoglycaemic animals and kept it within the normal values (68.33 ± 6.7 mm Hg). Acetyl-L-carnitine increased myocardial carnitine content leading to the attenuation of hypoglycaemia-induced oxidative stress, which was evaluated through measurement of the oxidative stress biomarkers such as inducible nitric oxide synthase, NAD(P)H quinone dehydrogenase-1, heme oxygenase-I, and glutathione S-transferase. Moreover, acetyl-L-carnitine prevented induction of gene expression of cardiac hypertrophy markers during hypoglycaemic conditions, which was assessed via the evaluation of mRNA expression of α-myosin heavy chain and β-myosin heavy chain. These findings demonstrate that carnitine might play an essential role in prevention of hypoglycaemia-induced hypertension and cardiac hypertrophy through providing energy and antioxidants to the cardiovascular system.

Abstract
OBJECTIVE We aimed to examine the utility of electronically patient-reported data (e-PRD) in exploring the risk of diabetes-related hypoglycemia and to evaluate hypoglycemia prediction by the quality of life (QoL) measures. METHODS A retrospective analysis of e-PRD for patients with diabetes mellitus who completed the American Diabetes Association's Low Blood Sugar Questionnaire (Hypo-Q) and the Patient-Reported Outcomes Measurement Information System (PROMIS) for QoL assessment. Associations between Hypo-Q answers and PROMIS scores were described using Spearman correlations and 95% confidence intervals, or medians and quartiles. RESULTS Records of 538 subjects were reviewed; 55% were female, 95% were non-Hispanic, with a mean age (± SD) of 53 ± 15 years. Patients with type 1 diabetes had a longer disease duration and more hypoglycemic episodes (P<.001) with higher PROMIS Physical and Mental T-scores (P<.001, both), when compared to patients with type 2 diabetes. The latter had a higher number of co-existing conditions. Having >5 episodes of either moderate or severe hypoglycemia in a year were reported by 18% and 5% of all patients, respectively. Mean PROMIS Physical and Mental health T-scores were 46 ± 10 and 47 ± 10, respectively. Patients with fewer moderate and severe hypoglycemic episodes had better Physical (P = .047 and P<.001) and Mental (P = .015 and P<.001) PROMIS T-scores with incremental decreases in the odds of hypoglycemia with each point increase in PROMIS T-scores. CONCLUSION e-PRD of QoL measures and Hypo-Q were effective in exposing the risks for hypoglycemia and reproducing published findings with significant associations between QoL measures and hypoglycemia risks while providing new insights.

Abstract
OBJECTIVE The aim of the study was to estimate the prevalence rate and risk factors of medication-related problems (MRPs) leading to hospital admissions in Thai older patients. METHODS A prospective observational study was carried out in nine hospitals in Lower Northern Thailand. Participants admitted to internal medicine units were screened for suspected MRPs by clinical pharmacists using medical record review and patient interview. Three experts evaluated suspected MRPs independently using the following four criteria: contribution of MRPs to hospital admissions, causality, severity, and preventability. RESULTS Of 1776 patients admitted during the study period, 56 patients (3.2%) were deemed to have causal MRPs; 24 (42.9%) were judged as preventable. The medication groups most commonly associated with MRPs were those targeting the endocrine system, especially antidiabetic medications, such as metformin and glipizide. Preventable MRPs were usually manifest as hypoglycemia (n = 15, 62.5%). The variables that contributed to hospital admissions associated with MRPs were age (odds ratio = 1.92; 95% confidence interval [CI] = 1.06-3.47), starting a new drug within 1 week (odds ratio = 2.31; 95% CI = 1.08-4.95), or within 1 month (odds ratio = 2.17; 95% CI = 1.05-4.48). CONCLUSIONS Hospital admissions associated with MRPs in Thai older patients continue to burden the Thai healthcare system of which nearly half were preventable. Further studies should consider analysis of costs and include hepatic and renal function status of participants.

Front Endocrinol (Lausanne) 2021; 12:624423. [PMID: 33763029 PMCID: PMC7984365 DOI: 10.3389/fendo.2021.624423] [Citation(s) in RCA: 31] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Accepted: 01/11/2021] [Indexed: 01/14/2023] Open
Abstract
Ramadan is the 9th month of the lunar calendar during which Muslims abstain from food and drink between dawn and sunset for 30 consecutive days. Ramadan fasting is observed by all healthy Muslim adults, as well many Muslims with type 2 diabetes (T2DM). Hypoglycemic events (HE) are a serious complication associated with diabetes management and are associated with increased cardiovascular disease risk. Conflicting results have been reported concerning the incidence of HE among people with T2DM observing Ramadan fasting. This review summarizes available scientific evidence on the occurrence of HE and the effects of different moderators on the incidence of HE among patients with T2DM during Ramadan. We conducted a systematic review of available observational studies and randomized controlled trials (RCTs) for patients with T2DM who fasted during Ramadan, with HE as the primary outcome. Ten databases were searched for relevant studies from inception until October 31, 2020. In total, 68 studies (35 RCTs and 33 observational studies) met the inclusion criteria. Non-sulfonylureas hypoglycemic medications showed superior effects in lowering the incidence of HE over sulfonylureas hypoglycemic medications. Variable moderators were associated with experiencing HE during Ramadan in both observational studies and RCTs, including sex, geographical location, body anthropometric indicators, season, dietary behaviors, fasting duration, time since diagnosis, and pre-fasting education. This comprehensive systematic review covered the largest number of observational and clinical studies investigating the impact of Ramadan on HE among patients with T2DM. The study highlights the significance of different moderators that influence the effect of Ramadan fasting on HE, including dietary behaviors, fasting time duration, sex, season, country, pre-fasting education, age, and time since diagnosis. The study also highlighted the impact of different hypoglycemic medications on HE and noted the superiority of non-sulfonylureas over sulfonylureas hypoglycemic medications in lowering the risk for hypoglycemia in people with T2DM during Ramadan fasting.

The Safety and Efficacy of Second-Generation Basal Insulin Analogues in Adults with Type 2 Diabetes at Risk of Hypoglycemia and Use in Other Special Populations: A Narrative Review. Diabetes Ther 2020; 11:2555-2593. [PMID: 32975710 PMCID: PMC7547921 DOI: 10.1007/s13300-020-00925-8] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2020] [Accepted: 09/03/2020] [Indexed: 12/16/2022] Open
Abstract
Hypoglycemia is a major barrier impeding glycemic control in persons with type 2 diabetes mellitus and creates a substantial burden on the healthcare system. Certain populations that require special attention, such as older adults and individuals with renal impairment, a longer duration of diabetes or those who have experienced prior hypoglycemia, may be at a higher risk of hypoglycemia, particularly with insulin treatment. Second-generation basal insulin analogues (insulin glargine 300 U/mL and degludec) have demonstrated reductions in hypoglycemia compared with insulin glargine 100 U/mL although evidence of this benefit across specific populations is less clear. In this review we summarize the literature with respect to the efficacy and safety data for second-generation basal insulin analogues in adults with type 2 diabetes mellitus who are at risk of hypoglycemia or who require special attention. Randomized controlled trials, meta-analyses and real-world evidence demonstrate that the use of second-generation basal insulin analogues is associated with less hypoglycemia compared with insulin glargine 100 U/mL without compromising glycated hemoglobin control. A reduced risk of hypoglycemia with second-generation basal insulin analogues was evident in older adults and in individuals with obesity, renal impairment, a history of cardiovascular disease or a long duration of insulin use. Further studies are needed in other populations, including those with more severe renal impairment or hepatic dysfunction, the hospitalized population and those with cognitive impairment. Overall, less hypoglycemia associated with second-generation basal insulin analogues may help reduce barriers for insulin use, improve adherence and offset the costs of hypoglycemia-related healthcare resource utilization.

Abstract
AIMS AND OBJECTIVES To summarize and thematize fear of hypoglycemia (FOH) in individuals with type 1 diabetes (T1D) and type 2 diabetes (T2D) to provide a theoretical basis for the development of effective interventions. BACKGROUND FOH is common in this population and can reduce quality of life(QOL) and adversely impact upon diabetes self-care management. DESIGN a systematic review METHODS: Articles published between 2000 and 2019 were searched in PubMed, MEDLINE, EMBASE, Web of Science and three Chinese databases (CNKI, Wan-fang data and VIP). Eligible articles were selected using the Preferred Reporting Item for Systematic Review and Meta-analysis (PRISMA) guidelines. The quality of all articles finally included was evaluated by the Joanna Briggs Institute (JBI) Critical Appraisal tools. RESULTS Eighteen studies from 8654 papers were included. The sample size of each study ranged from 48 to 3812 subjects. FOH negatively impacted QOL, particularly psychosocial functioning, daily life and sleep quality. CONCLUSIONS FOH is a common and serious problem for patients, leading to poor QOL. It has been suggested that psychological concerns, QOL and effective countermeasures in individuals with T1D and T2D should be taken seriously. Advanced technology should be evaluated for its benefits before being used by patients. RELEVANCE TO CLINICAL PRACTICE The review highlights that FOH negatively impacts QOL, including psychosocial factors, daily life and sleep quality. Healthcare providers should develop targeted and professional assessment tools for FOH and QOL for patients with T2D, especially for patients who are about 60 years old. Advanced technology should be evaluated for its benefits before being used by patients.

Abstract
A cost-effective portable glucose monitoring system with remote data access based on a novel e-oscilloscope was developed using a glucose biofuel cell and a capacitor circuit interfaced to an ESP8266 microcontroller programmed to convert the charge/discharge rates of the capacitor functioning as a transducer. The capacitor charge/discharge rates were converted into glucose concentration readings that is monitored remotely. The glucose monitoring system comprise a glucose biofuel cell, a charge pump circuit, a capacitor and an ESP microcontroller. The anode was fabricated by modifying a gold microwire with nanoporous colloidal platinum (Au-co-Pt) and the cathode was constructed using a mesh dense network of multiwalled carbon nanotubes modified with bilirubin oxidase, respectively. The glucose monitoring system showed sensitivity of 1.18 Hz/mM · cm2 with a correlation coefficient of 0.9939 with increasing glucose concentration from 1 mM to 25 mM. In addition, the glucose monitoring system exhibited optimal operation at a pH of 7.4 and 37 °C, which is ideal for physiological glucose monitoring.

Abstract
BACKGROUND The ambulatory glucose profile (AGP) uses the wealth of data that are generated by continuous glucose monitoring, including flash glucose monitoring technologies, to provide a visual representation of glucose levels over a typical standard day of usually the most recent two weeks for a person with diabetes and helps to identify patterns and trends in glucose control. The AGP allows certain patterns of glucose levels to be identified and analyzed, such that treatment adjustments can be made, and new individual treatment goals can be defined. This helps to ensure increased treatment satisfaction and adherence, quality of life, and an improvement in metabolic management for people with diabetes. OBJECTIVE To date, a range of approaches exists for interpreting the information contained in an AGP, with different priorities given to identifying and targeting patterns of hypoglycemia and the degree of variability and stability underlying the glucose levels. The objective of the present recommendation is to describe the steps for assessing an AGP in detail and to illustrate these steps using visual examples. CONCLUSION This paper describes the consensus recommendations from a group of German expert diabetologists on the necessary steps for assessing an AGP in a structured and detailed way and to explain these steps using practical clinical examples.

Abstract
BACKGROUND Hypoglycemia, a common complication of insulin therapy in patients with diabetes, is associated with increased hospital morbidity and mortality. Hypoglycemia may be underrecognized in hospitalized patients due to impaired counter regulation or reduced recognition. Beta blocker (BB) use may also affect hypoglycemia recognition. AIM To characterize hypoglycemia unawareness and patient perceived hypoglycemia burden in hospitalized patients. MATERIALS AND METHODS Over a 2-month period, we prospectively identified non-critically ill cognitively intact hospitalized insulin-requiring patients who were undergoing bedside glucose monitoring. Participants were included if they reported any episode of hypoglycemia in the 30 days prior to admission and either had no BB use or were on stable BB for 90 days. Hypoglycemia unawareness was assessed using the Clarke score and burden of hypoglycemia was assessed with the (TRIM-HYPO) score. RESULTS Of the 46 participants, 20 were not taking a BB and 26 were taking a BB. Predictors of hypoglycemia during admission included glucose coefficient of variation and hospital length of stay. Nine participants (20%) had hypoglycemia unawareness (Clarke score ≥4). Participants with a history of coronary artery disease were less likely to have impaired awareness. Burden of hypoglycemia was associated with more hypoglycemia and longer hospital length of stay. There were no differences in measures of hypoglycemia unawareness or burden according to BB use. CONCLUSIONS BB use was not related to hypoglycemia unawareness, or burden in hospitalized high risk patients. Hypoglycemia burden may identify patients at higher risk of hypoglycemia during admission.

Abstract
INTRODUCTION Hypoglycaemia constitutes a significant barrier to achieving glycaemic control with insulin in both Type 1 (T1DM) and Type 2 diabetes mellitus (T2DM). The International Operations Hypoglycaemia Assessment Tool (IO HAT) study was designed to determine the incidence of hypoglycaemia in insulin-treated patients with T1DM and T2DM. METHODS The IO HAT study retrospectively and prospectively assessed the incidence of hypoglycaemia in patients with insulin-treated diabetes mellitus in nine countries. This sub-analysis included patients from Singapore with T1DM or T2DM who were aged ≥ 21 years and had completed two self-assessment questionnaires (SAQ1 and SAQ2). RESULTS Of the 50 T1DM and 320 T2DM patients who completed the SAQ1, 39 T1DM and 265 T2DM patients completed SAQ2; 100% and 90.9%, respectively, experienced at least one hypoglycaemic event prospectively. The incidence rates of any hypoglycaemia were 49.5 events per patient-year (EPPY) and 16.1 EPPY for T1DM and T2DM patients, respectively, in the four-week prospective period. Hypoglycaemia rate did not differ in terms of glycated haemoglobin level. The vast majority of T1DM or T2DM patients (92.0% and 90.7%, respectively) knew the overall definition of hypoglycaemia before study participation, although over half of the patients (T1DM 54.0%, T2DM 51.9%) defined hypoglycaemia based only on symptoms. CONCLUSION High proportions of insulin-treated patients with diabetes mellitus in Singapore reported hypoglycaemic events prospectively, showing that they had underreported hypoglycaemic episodes retrospectively. Patient education can help in improving hypoglycaemia awareness and its management in the region.

Abstract
Background There are several treatments to cure type 2 diabetes (T2D) and every one of them has certain attributes which is lead patients and specialists to have different preferences and select power. Therefore, we did this systematic study to evaluate patients̓ and physicians̓ preferences for type 2 diabetes medications by extracting attributes of anti-diabetic medications and identifying their relative importance. Methods We searched the PubMed, Ovid, Web of science, Scopus and Embase databases for articles which have been published on or before May 8th, 2018(The start time of the search in our study was May 8th, 2018). Results The searches identified 3346 studies, of which 17 (from 2009 to 2017) were included in the final synthesis and 27 attributes of type 2 anti-diabetic have been investigated. The most important attributes are changes of blood glucose and HbA1c level, hypoglycemia events, weight changes, gastrointestinal complications, cardiovascular effects, medicines cost, and administration mode and dosage of medicines. Conclusion physicians and patients prefer antidiabetics which is reduce blood glucose and HbA1c level effectively and have low side effects too (hypoglycemic event, cardiovascular and gastrointestinal). The effect of weight reduction, low cost, low dosing and low frequency of using. Health care providers, Specialist, and manufacturers should consider to these attributes in treatment process and marketing. It can increase adherence to management approaches, and reduce morbidity of patients with type 2 diabetes.

Aljunid SM, Aung YN, Ismail A, Abdul Rashid SAZ, Nur AM, Cheah J, Matzen P. Economic burden of hypoglycemia for type II diabetes mellitus patients in Malaysia. PLoS One 2019; 14:e0211248. [PMID: 31652253 PMCID: PMC6814276 DOI: 10.1371/journal.pone.0211248] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2019] [Accepted: 10/15/2019] [Indexed: 01/08/2023] Open
Abstract
This study mainly aims to identify the direct cost and economic burden of hypoglycemia for patients with type II diabetes mellitus in Malaysia. A cross-sectional study explored the cost incurred for hypoglycemia among patients admitted to University Kebangsaan Malaysia Medical Centre (UKMMC). The study covered patients aged 20-79 years hospitalized with a primary diagnosis of ICD-10 hypoglycemia and discharged between January 2010 and September 2015 according to the casemix database. A costing analysis was done through a step-down approach from the perspective of health providers. Cost data were collected for three levels of cost centers with the help of a hospital-costing template. The costing data from UKMMC were used to estimate the national burden of hypoglycemia among type II diabetics for the whole country. Of 244 diabetes patients admitted primarily for hypoglycemia to UKMMC, 52% were female and 88% were over 50 years old. The cost increased with severity. Managing a hypoglycemic case requires five days (median) of inpatient stay on average, with a range of 2-26 days, and costs RM 8,949 (USD 2,289). Of the total cost, 30% related to ward (final cost center), 16% to ICU, and 15% to pharmacy (secondary-level cost center) services. Considering that 3.2% of all admissions were hypoglycemia related, the total annual cost of hypoglycemia care for adult diabetics in Malaysia is estimated at RM 117.4 (USD 30.0) million, which translates to 0.5% of the Ministry of Health budget. Hypoglycemia imposes a substantial economic impact even without the direct and indirect cost incurred by patients and other cost of complications. Diabetic management needs to include proper diabetic care and health education to reduce episodes of hypoglycemia.

The cytokine alterations/abnormalities and oxidative damage in the pancreas during hypertension development. Pflugers Arch 2019; 471:1331-1340. [PMID: 31624954 PMCID: PMC6814849 DOI: 10.1007/s00424-019-02312-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 08/30/2019] [Accepted: 09/20/2019] [Indexed: 02/04/2023]
Abstract
The aim of the present study was to compare the content of cytokines, chemokines, and oxidative stress markers in the pancreas of spontaneously hypertensive rats (SHRs) and Wistar Kyoto Rats (WKYs) serving as controls. Enzyme-like immunosorbent assay (ELISA) and biochemical methods were used to measure pancreatic levels of interleukin-1ß, interleukin-6, tumor necrosis factor α, transforming growth factor β, RANES, monocyte chemoattractant protein 1, interferon gamma-induced protein 10, malondialdehyde, and sulfhydryl groups. The results showed that the pancreatic concentrations of all studied cytokines and chemokines did not differ between 5-week-old SHRs and WKYs, except RANTES which was significantly reduced in juvenile SHRs. In 10-week-old animals, except interleukin-1ß, the levels of all these proteins were significantly reduced in SHRs. The pancreatic levels of malondialdehyde were significantly reduced in 5-week-old SHRs and significantly elevated in 10-week-old SHRs while the contents of sulfhydryl groups were similar in both rat strains at any age studied. In conclusion, these data provide evidence that in maturating SHRs, the pancreatic levels of cytokines and chemokines are significantly reduced, while malondialdehyde significantly elevated. This suggests that in the pancreas of mature SHRs, the inflammation process is suppressed but there is ongoing oxidative damage.

Abstract
Glucagon-like peptide 1 (GLP-1) and glucagon-like peptide 2 (GLP-2) are proglucagon derived peptides that are released from gut endocrine cells in response to nutrient intake. These molecules are rapidly inactivated by the action of dipeptidyl peptidase IV (DPP-4) which limits their use as therapeutic agents. The recent emergence of three-dimensional structures of GPCRs such as GLP-1R and glucagon receptor has helped to drive the rational design of innovative peptide molecules that hold promise as novel peptide therapeutics. One emerging area is the discovery of multifunctional molecules that act at two or more pharmacological systems to enhance therapeutic efficacy. In addition, drug discovery efforts are also focusing on strategies to improve patient convenience through alternative routes of peptide delivery. These novel strategies highlight the broad utility of peptide-based therapeutics in human disease settings where unmet needs still exist.

Short-term cost-utility of degludec versus glargine U100 for patients with type 2 diabetes at high risk of hypoglycaemia and cardiovascular events: A Canadian setting (DEVOTE 9). Diabetes Obes Metab 2019; 21:1706-1714. [PMID: 30924579 PMCID: PMC6618053 DOI: 10.1111/dom.13730] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/16/2018] [Revised: 03/06/2019] [Accepted: 03/26/2019] [Indexed: 01/24/2023]
Abstract
AIMS To evaluate the short-term cost-effectiveness of insulin degludec (degludec) vs insulin glargine 100 units/mL (glargine U100) from a Canadian public healthcare payer perspective in patients with type 2 diabetes (T2D) who are at high risk of cardiovascular events and hypoglycaemia. MATERIALS AND METHODS A decision analytic model was developed to estimate costs (2017 Canadian dollars [CAD]) and clinical outcomes (quality-adjusted life years [QALYs]) with degludec vs glargine U100 over a 2-year time horizon. The model captured first major adverse cardiovascular event, death, severe hypoglycaemia and insulin dosing. Clinical outcomes were informed by a post hoc subgroup analysis of the DEVOTE trial (NCT01959529), which compared the cardiovascular safety of degludec and glargine U100 in patients with T2D who are at high cardiovascular risk. High hypoglycaemia risk was defined as the top quartile of patients (n = 1887) based on an index of baseline hypoglycaemia risk factors. RESULTS In patients at high hypoglycaemia risk, degludec was associated with mean cost savings (CAD 129 per patient) relative to glargine U100, driven by a lower incidence of non-fatal myocardial infarction, non-fatal stroke and severe hypoglycaemia, which offset the slightly higher cost of treatment with degludec. A reduced risk of cardiovascular death and severe hypoglycaemia resulted in improved effectiveness (+0.0132 QALYs) with degludec relative to glargine U100. In sensitivity analyses, changes to the vast majority of model parameters did not materially affect model outcomes. CONCLUSION Over a 2-year period, degludec improved clinical outcomes at a lower cost as compared to glargine U100 in patients with T2D at high risk of cardiovascular events and hypoglycaemia.

Abstract
Objectives This study aimed to evaluate the incidence of hypoglycaemia among insulin-treated patients with type 1 diabetes mellitus (T1DM) or type 2 diabetes mellitus (T2DM) from the United Arab Emirates (UAE) cohort of the non-interventional International Operations-Hypoglycaemia Assessment Tool study. Methods This cross-sectional observational study took place at 25 patient care centres in the UAE from October 2014 to May 2015. All adult patients with T1DM or T2DM who had been treated with insulin for >12 months were included. Self-assessment questionnaires and patient diaries were used to determine the incidence of documented hypoglycaemia both prospectively (four weeks after baseline) and retrospectively (six months and four weeks before baseline for severe and non-severe hypoglycaemic events, respectively). Results A total of 325 patients were enrolled in the study, of which 82 (25.2%) had T1DM and 243 (74.8%) had T2DM. Among patients with T1DM, 71.4% reported hypoglycaemic events retrospectively, with an incidence rate (IR) of 102.8 events per patient-year (PY), while 95% reported hypoglycaemic events prospectively, with an IR of 63.1 events per PY. Additionally, 56.3% of patients with T2DM reported hypoglycaemic events retrospectively, with an IR of 42.2 events per PY, while 91.9% reported hypoglycaemic events prospectively, with an IR of 33.3 events per PY. Conclusion The prevalence and incidence of hypoglycaemia were high among insulin-treated patients with T1DM and T2DM in the UAE. Individualised glycaemic goals, patient education and blood glucose monitoring may help to reduce the incidence of hypoglycaemia in this population.

Evaluation of Hypoglycemia and Associated Factors among Patients with Type 1 Diabetes on Follow-Up Care at St. Paul's Hospital Millennium Medical College, Addis Ababa, Ethiopia. J Diabetes Res 2019; 2019:9037374.

Abstract
BACKGROUND Hypoglycemia is one of the most common acute complications of type 1 diabetes mellitus (T1DM). The knowledge of the factors associated with hypoglycemia will help in the prevention and management of the problem. Therefore, this study was conducted to assess hypoglycemia and its associated factors among T1DM patients who attended the diabetes outpatient clinic of St. Paul's Hospital Millennium Medical College (SPHMMC). METHODS A cross-sectional study was conducted at the diabetes clinic of SPHMMC. Data on sociodemographic and clinical characteristics including duration of diabetes, type of insulin they have been taking, the factors associated with hypoglycemia, and the severity stage of hypoglycemia was obtained. Data was collected using a structured questionnaire and chart review. Multivariate logistic regression model was used to identify factors associated with hypoglycemia. RESULT Out of the 247 participants who were recruited into the study, 233 (94.3%) of them experienced hypoglycemia. A total of 6.9 events of hypoglycemia per patient per year happened. Particularly, the events were categorized as 3.1 mild events, 2.3 moderate events, and 0.93 severe events of hypoglycemia. Shorter duration of diabetes history (<1 year) was significantly associated with less experience of hypoglycemia (AOR = 0.09, 95% CI: 0.01-0.90). However, blood glucose monitoring at home was found to be significantly associated with more report of hypoglycemia (AOR = 5.77, 95% CI: 1.16-28.66). CONCLUSION The prevalence of hypoglycemia among T1DM patients was found as substantially high. Self/family blood glucose monitoring at home could not guarantee to minimize the occurrence of hypoglycemia events. Finger stick home blood glucose monitoring should be given a special attention. Therefore, the involvement of health care providers in diabetes care should be encouraged to address the occurrence of hypoglycemia in T1DM patients.
