Polycystic ovary syndrome is a very common condition that is associated with metabolic complications. Patients with polycystic ovary syndrome exhibit insulin resistance and are at greater risk to develop type 2 diabetes. This syndrome is heterogeneous, classified according to 4 phenotypes (A-D). It seems that certain phenotypes are less exposed to insulin resistance and metabolic complications. However, only a few studies have evaluated the glucose profile according to phenotype. New technologies now make it possible to monitor glucose levels continuously. The aim of this project is to evaluate glucose profile parameters using continuous glucose monitoring, and to compare these profiles according to different PCOS phenotypes.
NCT05441982
Animal and observational research in humans suggest that specific types of non-nutritive sweeteners (NNS) may impair glycemic control. However, whether NNS consumption impacts glucose homeostasis in middle-aged/older adults with prediabetes is unknown, and potential mechanisms by which this could occur have yet to be identified. The overall objective of this R21 proposal is to establish proof-of-concept for alterations in glucose homeostasis following intake of saccharin, but not acesulfame potassium, in middle-aged/older adults with prediabetes compared to a eucaloric diet with no NNS.
NCT06648174
This study aims to examine the effects of a lifestyle intervention based on a health belief model (HBM) supported by mobile health (mHealth) and the impact of continuous glucose monitoring (CGM) on maternal glycemic parameters, cardiometabolic risk, health behavior and infant's outcomes among women diagnosed with gestational diabetes mellitus (GDM).
NCT07298850
This study evaluates the effect of using a real-time continuous glucose monitoring (CGM) system on blood sugar control in people with type 2 diabetes who do not use insulin. Participants will wear a CGM device (CareSens Air) for a total of two weeks. During the first week, the device will be set to "blinded mode," meaning participants cannot see their glucose readings. During the second week, the device will be switched to "unblinded mode," allowing participants to view their glucose levels and trends in real-time. The study aims to determine if simply seeing real-time glucose data can help patients improve their blood sugar control (such as increasing the time their blood sugar is in the target range) without receiving additional structured education on diet or exercise. Researchers will compare the glucose data collected during the blinded week with the data from the unblinded week.
NCT07026903
The goal of this randomized control study is to learn if continuous glucose monitoring (CGM) can aid in weight loss in overweight/obese women with no other chronic condition. The primary hypothesis is that insights from CGM aid in greater weight loss, and the secondary hypothesis is that the use of CGM reduces the dropout rate from a three-month exercise program. Research will compare the results of weight loss after inclusion into 3 month physical exercise and diet counselling program between experimental group (women assigned to wear CGM) and control group (women without CGM). All participants will be included in the same physical exercise program with a fitness coach (3 times weekly for 60 minutes per sessions, three different resistance trainings), and will be given a calorie-controlled diet based on a weekly menu.
NCT06127433
This study aims to explore the effectiveness and safety of the in-hospital-out-of-hospital synergistic short-term insulin intensive therapy model based on patch insulin pump and continuous glucose monitoring technology through a randomized controlled study, and evaluate the possibility of blood glucose parameters derived from continuous glucose technology in predicting long-term blood glucose remission, so as to provide important reference data for the precision, intelligence, and integrated improvement of short-term insulin intensive therapy.
NCT05947916
The prevalence of type 2 diabetes mellitus (T2DM) in women of childbearing age is increasing rapidly, and low glucose compliance leads to an increased risk of adverse pregnancy outcomes for mothers and infants during pregnancy in women with T2DM. Real-time continuous glucose monitoring (CGM) is an important tool for glucose monitoring and patient education, as it can continuously record blood glucose throughout the day and provide real-time feedback on high and low blood glucose levels. This is a multicenter, open-label, randomized controlled clinical study to investigate the efficacy, safety, and maternal and infant pregnancy outcomes of using real-time CGM monitoring compared with conventional self-monitoring of blood glucose (SMBG) on the basis of multidisciplinary management in pregnant women with T2DM. One hundred and twenty pregnant women with T2DM in early pregnancy who were enrolled in intensive insulin therapy were randomly divided into the real-time CGM group and the conventional SMBG group. The real-time CGM intervention group wore real-time CGM for more than 50% of the pregnancy in addition to regular SMBG; the control group only performed regular SMBG. Both groups wore Medtronic iPro 2 for 3 days in early, mid and late pregnancy, and the time in the target range of blood glucose (TIR) was recorded in a blinded manner. Primary outcome: differences in TIR between the two groups of pregnant women in early, mid, and late pregnancy. Secondary outcomes included differences in glycated hemoglobin, hypoglycemia, insulin dose before delivery, pregnancy weight gain, and maternal and infant pregnancy outcomes.
NCT05038761
Researchers are looking for a better way to help Chinese people who have diabetes to monitor their blood sugar (blood glucose) situation. There are 2 types of diabetes. In people with type 1 diabetes, the body's immune system attacks and destroys cells in the pancreas that produce a hormone called insulin. In people with type 2 diabetes, the body does not make enough insulin or does not use insulin well. This results in high blood glucose levels. Over time, high blood glucose levels can cause damage to certain parts of the body. These include the eyes, the kidneys, the nerves, and the heart. There are tests and devices available for doctors and patients to measure blood glucose levels. Repeated measurements of blood glucose levels are needed to see whether the treatments that prevent blood glucose levels from becoming too high work well and to notice when the blood glucose is decreasing too much. Such tracking of the blood glucose is also called blood glucose monitoring. Blood glucose monitoring tests and devices can however be difficult to use, and one test or device may not work for all patients. Researchers think that better monitoring systems would help patients improve the control of their blood glucose levels. This could help stop their diabetes from getting worse. In this study, the researchers want to learn more about how well a new monitoring system called CGM works in Chinese patients with diabetes. CGM is a continuous glucose monitoring system. It regularly measures the level of glucose in the tissue throughout the day and night. CGM is made up of a small sensor that patients apply in the belly region where it is placed just under the skin, into the so-called subcutaneous tissue. The sensor measures the level of glucose in the fluid that surrounds cells in the subcutaneous tissue. It also has a transmitter which attaches to the sensor and sends via Bluetooth the results to a device, which can instantly display the glucose level. The glucose levels can then be used to adjust the treatment. The main purpose of this study is to learn how well CGM monitors glucose levels in Chinese patients when used in usual practice. To answer this question, the researchers will compare the glucose levels collected with the CGM monitor to the blood glucose levels collected with another type of monitoring called "venous blood glucose testing". This is where a blood sample is taken from the veins, and then the level of glucose in the blood sample is measured. The study will include adult Chinese patients who have type 1 or type 2 diabetes and who the study doctors think need to monitor their diabetes using CGM and venous blood glucose testing. There will be no treatments given as part of this study. The device will be worn up to a maximum of 14 days. The patients will get training on how to use the CGM monitor and will attach it to their belly on Day 1 of the study. The researchers will then collect the information about their glucose levels. The study doctors will also take blood samples and measure blood glucose levels using venous blood glucose testing. They will compare the glucose levels recorded from the blood samples to the glucose levels recorded by CGM at the closest time points. After wearing CGM for 14 days, the study doctors will remove it from the patients' bellies. About 3 days later, the researchers will call the patients to check if they have any swelling or areas of rash where CGM was worn. The patients may also take photos of the area and send these to the study doctors. During the study, the study staff will: * take blood samples as part of the usual care * compare glucose levels recorded by CGM to the levels recorded from the venous blood glucose tests * check the skin for any swelling or areas of rash where CGM was worn * record any instances of CGM errors or alarms for when glucose levels are too high or too low * check the patients' overall health * ask the patients about how they are feeling and what medical problems they are having.
NCT04411277
Prospective observational cohort study. Elderly patients \>65 years with type 2 diabetes mellitus (T2DM) on insulin therapy and HbA1c between 7% and 9%, with or without oral agents, will be identified from medical records and invited to participate. Patients will wear a FreeStyle Libre Flash CGM during a 6-week study period. Using CGM technology, we will assess an efficacy outcome : time in range (TIR) between 70-180 mg/dl and a safety outcome: incidence of hypoglycemia (time below range (TBR) less than 70, 54, and 40 mg/dl in insulin treated older adults with T2DM. Patients will return to clinic every 2 weeks for new continuous glucose monitoring (CGM) placement, assessment of glycemic control and hypoglycemia, adherence to therapy and CGM use. CGM data will be downloaded every 2 weeks.
NCT04125160
The aim is to investigate the correlation between mean glucose measured by continuous glucose monitoring (CGM) and mean glucose estimated from glycated haemoglobin A1c (HbA1c) in persons with type 2 diabetes undergoing peritoneal dialysis compared with patients with type 2 diabetes and normal renal function. Furthermore, the aim is to compare CGM and HbA1c with glycated albumin and fructosamine.
NCT03253237
Introduction and objective: The key to optimal diabetes management is tight glucose control. Hemoglobin A1c is the gold standard to assess glycemic control but in cases of unrecognized hypoglycemia, confusing nighttime events or in cases of large variations in blood glucose, a haemoglobin A1c can not detect specific movement of blood glucose. Continuous glucose monitoring (CGM) provides informations of glucose levels in a real-time format and may be helpful for making the personalized therapy decisions desired in the era of precision medicine. Our aim is to analyse the benefit of tracking patterns of glucose values by using continuous glucose monitoring (CGM) in patients with T2DM in family medicine office.
NCT01883622
Continuous glucose monitoring (CGM) methods provide details of magnitude and duration of glucose fluctuations, giving a unique insight on daily blood sugar control. Limited data are available on glucose variability (GV) in pregnancy. The aim of this study was to assess GV in normal pregnant women and cases of type 1 diabetes mellitus or gestational diabetes (GDM), and its possible association with HbA1c.
