Abstract
AIMS: Ramadan is a holy month for the Muslim community. Fasting Ramadan is directed by a systematic alteration in eating habits, sleeping times, and daily physical activities that optimize blood glucose levels. This study aims to evaluate the effects of structured education on safe fasting among diabetic patients. METHODS This study included diabetic patients with eligibility for the Ramadan fast. The control group included 494 patients who received standard diabetes education, while the intervention group included 407 patients who attained structured diabetes education. The patients were required to register their responses following the written, structured questionnaires before and after Ramadan fasts. In addition, patients were advised to keep a log of their hypoglycemic episodes. RESULT This study showed that structured diabetes education improved the blood glucose levels/glycemic control and outcomes of patients during their Ramadan fasting. The structured diabetes education helped reduce the incidence of hypoglycemic events and hyperglycemic crises. It also increased the acceptance and frequency of blood sugar level measurements among patients during Ramadan. CONCLUSION The standard diabetes management plan should include structured diabetes education measures to improve outcomes effectively. The providers should screen the patients with diabetes before Ramadan and educate them to improve their safe fasting practices.

Abstract
BACKGROUND AND HYPOTHESIS Patients with type-2 diabetes mellitus (T2DM) on multiple glucose-lowering therapies who fast during Ramadan are at increased risk of hypoglycemia. We have assessed the utility of the flash glucose monitoring system after adjusting the dose of insulin and sulphonylureas to mitigate the risk of hypoglycemia in patients with T2DM who fast during Ramadan. PATIENTS AND METHODS Patients with T2DM on either basal insulin or a sulphonylurea and at least 2 other glucose-lowering agents received structured education and adjustment of insulin or sulphonylurea dose according to the PROFAST Ramadan protocol. Glucose variability and episodes of hypoglycemia were assessed using the flash glucose monitoring system (Free Style Libre) before and during Ramadan. RESULTS A total of 33 patients with T2DM (on sulphonylurea (SU+) (n = 21), on basal insulin (BI+) (n = 12) aged 50.8 ± 1.6 years with a diabetes duration of 13.1 ± 6.5 years were studied. The average sensor glucose was 154 ± 34 mg/dl (8.5 ± 1.88 mmol/l) with 65.2% in the target range before Ramadan and the average sensor glucose was 156 ± 36 mg/dl (8.6 ± 2.0 mmol/l) with 67.1% in the target range during Ramadan. The incidence of hypoglycemia in the whole group (2.9 v 2.9) and in the SU+ (3.7 vs 3.0) and BI+ (1.7 vs 2.9) groups and eHbA1c (P = 0.56, P = 0.93), average glucose (P = 0.56, P = 0.92) and time within range (P = 0.63, P = 0.73) did not change in the SU+ and BI+ groups, respectively, before and during Ramadan. CONCLUSION Structured education with adjustment of the dose of glucose lowering medication alongside use of the FGMS can effectively mitigate the increased risk of hypoglycemia in patients with T2DM on multiple glucose-lowering therapies who fast during Ramadan.

Abstract
AIMS: This systematic review and meta-analysis aims to evaluate the safety and efficacy of the newer glucose lowering treatments on glycemic control, weight, blood pressure and hypoglycemia in patients with T2DM during Ramadan. METHODS A literature search was done in PubMed, Embase, and the Cochrane Library. Quality assessment was done using the ROBINS-I and Cochrane tools for risk of bias and analyses were performed using RevMan version 5.3. RESULTS A total of 20 studies were included in the meta-analysis. Dipeptidyl peptidase-4 inhibitors (DPP-4i) led to a significant reduction in HbA1c (%) (SMD -0.25) and a non-significant decrease in weight (kg) (SMD -1.06) during Ramadan. Glucagon-like peptide (GLP-1) agonist therapy was associated with a significant decrease in HbA1c (%) (SMD -0.68) and a non-significant decrease in weight (kg) (SMD -2.57) and systolic blood pressure (SBP) (mmHg) (SMD -3.50) after Ramadan. Sodium-glucose co-transporter 2 inhibitor (SGLT-2i) therapy was associated with a significant decrease in HbA1c (%) (SMD -0.51) and a non-significant decrease in weight (kg) (SMD -1.41), SBP (SMD -1.10) and diastolic blood pressure (DBP) (mmHg) (SMD -2.08) after Ramadan. CONCLUSIONS This systematic review and meta-analysis shows clinical benefits with the newer glucose lowering medications in patients with T2DM who fast during Ramadan.

Pancreatic β-Cell Function Is Associated with Augmented Counterregulation to In-Exercise Hypoglycemia in Type 1 Diabetes.
McCarthy, O, Pitt, J, Eckstein, ML, Moser, O, Bain, SC, Bracken, RM
Medicine and science in sports and exercise. 2021;(7):1326-1333
Abstract
PURPOSE This study aimed to investigate the influence of residual β-cell function on counterregulatory hormonal responses to hypoglycemia during acute physical exercise in people with type 1 diabetes (T1D). A secondary aim was to explore relationships between biomarkers of pancreatic β-cell function and indices of glycemia following acute exercise including the nocturnal period. METHODS This study involved an exploratory, secondary analysis of data from individuals with T1D who partook in a four-peroid, randomized, cross-over trial involving a bout of evening exercise followed by an overnight stay in a clinical laboratory facility. Participants were split into two groups: (i) a stimulated C-peptide level of ≥30 pmol⋅L-1 (low-level secretors [LLS], n = 6) or (ii) <30 pmol⋅L-1 (microsecretors [MS], n = 10). Pancreatic hormones (C-peptide, proinsulin, and glucagon), catecholamines (epinephrine [EPI] and norepinephrine [NE]), and metabolic biomarkers (blood glucose, blood lactate, and β-hydroxybutyrate) were measured at rest, during exercise with and without a hypoglycemic (blood glucose ≤3.9 mmol⋅L-1) episode, and throughout a 13-h postexercise period. Interstitial glucose monitoring was used to assess indices of glycemic variability. RESULTS During in-exercise hypoglycemia, LLS presented with greater sympathoadrenal (EPI and NE P ≤ 0.05) and ketone (P < 0.01) concentrations. Glucagon remained similar (P = 0.09). Over exercise, LLS experienced larger drops in C-peptide and proinsulin (both P < 0.01) as well as greater increases in EPI (P < 0.01) and β-hydroxybutyrate (P = 0.03). LLS spent less time in the interstitial-derived hypoglycemic range acutely postexercise and had lower glucose variability throughout the nocturnal period. CONCLUSION Higher residual β-cell function was associated with greater sympathoadrenal and ketonic responses to exercise-induced hypoglycemia as well as improved glycemia leading into and throughout the nocturnal hours. Even a minimal amount of residual β-cell function confers a beneficial effect on glycemic outcomes during and after exercise in people with T1D.

Abstract
Although religious guidance exempts some Muslims with type 2 diabetes from fasting during Ramadan, many choose to fast. The associated risks for fasting adults with diabetes includes hypoglycemia, hyperglycemia, ketoacidosis, dehydration, and thrombosis. Thus, it is important that healthcare professionals support individuals who choose to fast to minimize risks. We reviewed three epidemiologic studies to understand how fasting patterns during Ramadan and associated clinical outcomes in adults with type 2 diabetes have evolved over two decades (2000-2020). Over a period of time people with diabetes choosing to fast during Ramadan are displaying increasingly complex profiles in terms of their diabetes, with increased disease duration, greater body mass index, and elevated pre-Ramadan mean glycated hemoglobin levels. Despite this, in the most recent study, >85% of adults with type 2 diabetes still chose to fast. Increased risk of hypoglycemia remains a major concern despite some improvements over time, which could be attributable to enhanced education programs, and changes in treatment type and/or dose prior to and/or during Ramadan. Our review highlights the evolution in fasting patterns over two decades and serves as an update for healthcare professionals to provide appropriate guidance to ensure that Ramadan fasting is safe and rewarding.

Abstract
AIMS: Spain has been one of the worst affected countries by the COVID-19 pandemic. A very strict lockdown at home was imposed with a tough restriction of mobility. We aimed to evaluate the impact of this exceptional scenario on glucose profile of patients with type 1 diabetes (T1D) prone to hypoglycaemia using sensor-augmented pump (SAP). METHODS Patients with T1D prone to hypoglycaemia using SAP (640G Medtronic-Minimed®) for at least 6 months under the funding of a National Health Service were included in an observational, retrospective study. Data were collected in two periods: pre-lockdown (PL), February 23rd-March 7th and within lockdown (WL), April 1st to 14th 2020. The primary outcome was the difference in the proportion of time in target glucose range of 70-180 mg/dL (TIR). Additional glucometric data and total daily insulin were also analysed. RESULTS Fifty-nine patients were included: 33 women, age 46.17 ± 13.0 years and disease duration of 30.2 ± 12.0 years. TIR 70-180 mg/dL (67.6 ± 11.8 vs. 69.8 ± 12.0%), time > 180 (28.1 ± 13.6 vs. 25.5 ± 13.1%), time > 250 (6.9 ± 6.1 vs. 5.1 ± 4.8) and estimated HbA1c (6.94 ± 0.8 vs. 6.75 ± 0.7%) significantly improved (PL vs. WL, respectively, p < 0.05). Time in hypoglycaemia, coefficient of variation, sensor usage and total daily insulin dose remained unchanged. CONCLUSIONS Lockdown conditions imposed by the COVID-19 pandemic may be managed successfully in terms of glycaemia control by population with DT1 prone to hypoglycaemia using SAP. The strict daily routine at home could probably explain the improvement in the time in glycemic target without increasing the time hypoglycaemia.

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.

Suárez-Ayala, DV, Forero-Ronderos, C, Coll, M, Duran, P, Cespedes, C
Andes pediatrica : revista Chilena de pediatria. 2021;(4):617-625
Abstract
Diabetes Technology refers to the software or hardware that is designed to facilitate and improve the quality of life of the patient with diabetes Mellitus. A non-systematic literature search was carried out which included articles in English and Spanish about the use of continuous glucose monitoring (CGM) in pediatric patients with Type 1 diabetes Mellitus. This review summarizes the performance of the CGM, its accuracy, and classification. A chronological synthesis of the general evidence up to June 2020 was done including both adult and pediatric studies. Aspects of metabolic control were specified on the use of real-time and intermittent / flash CGM, such as reduction of HbA1c levels, reduction in frequency and severity of hypoglycemia, decrease in episodes of ketoacidosis and well being, and variables such as the Frequency of CGM use, which have been related to the improvement of the objectives of diabetes control. This review presents a chronological summary of the evidence for flash glucose monitoring in studies where only pediatric population is included and provides an account of diabetes technology recommendations that apply to pediatric population from the Ame rican Diabetes Association 2020 guideline, the International Society for Pediatric and Adolescent Diabetes 2018 recommendations.

Abstract
AIMS: Spain has been one of the worst affected countries by the COVID-19 pandemic. A very strict lockdown at home was imposed with a tough restriction of mobility. We aimed to evaluate the impact of this exceptional scenario on glucose profile of patients with T1D prone to hypoglycemia using standalone continuous glucose monitoring. METHODS Patients with T1D prone to hypoglycemia using multiple daily injections and either a Dexcom G5® or a Free Style Libre® CGM systems for at least 6 months under the funding of National Health Service were included in an observational, retrospective study. Data were collected in two periods: pre-lockdown (PL), February 23rd-March 7th and within lockdown (WL), April 1st-14th 2020. The primary outcome was the difference in the proportion of time in target glucose range of 70-180 mg/dL (TIR). Additional glucometric data were also analysed. RESULTS 92 patients were included: 40 women, age 42.8 ± 3.9 years, disease duration of 23.1 ± 12.6 years. Seventeen patients used Dexcom G5® and 75 Free Style Libre®. TIR 70-180 mg/dL (59.3 ± 16.2 vs 62.6 ± 15.2%), time > 180 (34.4 ± 18.0 vs 30.7 ± 16.9%), >250 (11.1 ± 10.6 vs 9.2 ± 9.7%) and Glucose Management Indicator (7.2 ± 0.8 vs 7.0 ± 0.8%) significantly improved (PL vs WL, respectively, p < 0.05). Time in hypoglycemia remained unchanged. CONCLUSIONS Lockdown conditions imposed by the COVID-19 pandemic may be managed successfully in terms of glycemic control by population with T1D prone to hypoglycemia using CGM. The strict daily routine at home could probably explain the improvement in the time in glycemic target without increasing the time in hypoglycemia.

Advances in therapy. 2020;(9):3816-3826
Abstract
INTRODUCTION FPG GOAL was a 24-week, open-label, treat-to-target randomized controlled trial which demonstrated that the optimal self-monitored fasting blood glucose (SM-FBG) target for most Chinese individuals with type 2 diabetes (T2D) using insulin glargine 100 IU/mL was 3.9-6.1 mmol/L. Individuals who achieved lower fasting plasma glucose (FPG) levels might achieve the target HbA1c of < 7% without increasing the risk of hypoglycemia. METHODS For this post hoc analysis, individuals were redivided into three groups based on their actual laboratory FPG levels at 24 weeks: level 1, ≤ 5.6 mmol/L; level 2, > 5.6 to ≤ 6.1 mmol/L; and level 3, > 6.1 to ≤ 7.0 mmol/L. RESULTS At week 24, 863 individuals with diabetes had available FPG data and 179, 122, and 179 individuals achieved FPG levels 1, 2, and 3, respectively. The proportion of individuals with HbA1c < 7% or HbA1c < 7% without hypoglycemia (≤ 3.9 or ≤ 3.0 mmol/L) was significantly higher in FPG levels 1 (p < 0.01) and 2 (p < 0.05) than in level 3. The least squares mean changes from baseline in HbA1c (- 1.77% and - 1.66% vs - 1.34%; both p < 0.001) and 2-h postprandial glucose (- 3.88 mmol/L and - 3.98 mmol/L vs - 3.22 mmol/L; both p < 0.05) were also significantly higher in FPG levels 1 and 2 compared with level 3. Linear regression analysis showed a moderate relationship between FPG and HbA1c levels at 24 weeks (r = 0.449). CONCLUSIONS Chinese individuals with T2D who achieved lower FPG levels with insulin glargine 100 IU/mL were more likely to achieve the recommended target HbA1c of < 7% compared with those with higher FPG levels.
