Use of Glucose Control Indicators for Risk Assessment and Treatment of Neurodevelopmental Disorders and Techniques for Establishing the Status of Chronic Glucose Control

Publication No.: US2023022094A1 26/01/2023

Applicant:

MOVSAS TAMMY [US]

CA_3163798_PA

Absstract of: US2023022094A1

Dysglycemia as a risk factor for neurodevelopmental disorder or developmental diabetes. The risk is assessed based on measurement of a glucose control indicator in a blood sample. One particular example of a neurodevelopmental disorder is retinopathy of prematurity in an infant. One particular example of a glucose control indicator is ‘comprehensive glycated hemoglobin fraction’ or ‘comprehensive glycated albumin fraction.’ This is calculated using ‘total whole blood protein’ in the denominator. In the case of chronic hyperglycemia, there is an increased risk of proliferative retinopathy of prematurity. In the case of chronic hypoglycemia, there is an increased risk of non-proliferative retinopathy of prematurity. This ‘total whole blood protein’ technique could also be used to determine the glucose control status in other types of patients.

Applicant:

DEXCOM INC [US]

AU_2022256146_A1

Absstract of: US2023013632A1

Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Applicant:

MY SALT AND SUGAR LLC [US]

Absstract of: US11553861B1

The present development is a method and device to monitor the salt level in a patient's blood without the need of laboratory facilities or intervention by medical personnel. The basic device is designed to measure the concentration of analytes, specifically sodium ion and potassium ion, in the patient's blood and to communicate the analyte level to the patient essentially instantaneously through a mobile monitor or display screen. In a variation, the device combines the analyte-concentration measuring function with a means for measuring the concentration of glucose in blood, and the blood analyte level and glucose level are displayed to the patient essentially instantaneously. Both the salt level device and the salt level+glucose level device may be further adapted to allow for the salt and glucose level data to be stored in a data storage base so the patient has an historical record of the concentration levels.
