A national task force that makes recommendations regarding preventive services such as screening tests, counseling services, and preventive medications is the U.S. Preventive Services Task Force, an independent, volunteer group of national experts in prevention and evidence-based medicine.

USPSTF: Not Enough Evidence Present For Screening T2DM In Children

Congress authorized AHRQ to provide USPSTF with technical, managerial, and administrative support.

United States National Prevention and Evidence-Based Medicine Task Force (US-NPEPTF) makes recommendations based on clinical evidence designed to improve the health of all Americans by recommending screenings, counseling, or medications.

USPSTF Not Enough Evidence Present For Screening T2DM In Children

USPSTF’s 15 volunteer members are primary care and preventive medicine practitioners, including internal medicine, family medicine, pediatrics, health psychology, obstetrics/gynecology, and nursing. Most members are practicing clinicians, and all are volunteers.

The USPSTF’s work was to be supported by the Department of Health and Human Services as required by Congress. It is the responsibility of AHRQ to provide the Task Force with research, technical support, and administrative assistance, as set forth by the 1998 Public Health Service Act and the 2010 Patient Protection and Affordable Care Act. 

An AHRQ representative assists with day-to-day operations coordinates the production of evidence reports and ensures that Task Force methods are consistently applied and that Task Force materials and recommendations are disseminated.

With the Chair of the Task Force’s guidance, the Director of AHRQ appoints new members of the USPSTF. Staff at AHRQ support the Task Force, but the Task Force is an independent body that works independently from AHRQ and HHS.

A combination of two factors causes Type 2 Diabetes Mellitus (T2DM): lowered insulin secretion by beta cells of the pancreas and insulin resistance in insulin-sensitive tissues.

Due to its importance in glucose homeostasis, insulin is tightly regulated by molecular mechanisms, including its synthesis and release. Deficiencies in any of these mechanisms can lead to metabolic imbalances. 

A review of T2DM is presented, along with an analysis of the molecular pathways that lead to this condition and insulin resistance. This is why we synthesize the data gathered up to now, focusing mainly on insulin synthesis, insulin release, insulin sensing, and downstream effects on insulin-sensitive tissues. 

In addition, the review explores the pathological conditions perpetuating T2DM, including dietary factors, physical activity, gastrointestinal abnormalities, and metabolic memory.

We also review some of the molecular mechanisms by which T2DM can lead to accelerated atherosclerosis development and cardiovascular risk as one of the most significant complications of T2DM.

According to the U.S. Preventive Services Task Force, there is insufficient evidence to evaluate the benefits and harms of screening children and adolescents for type 2 diabetes. Based on this conclusion, a draft recommendation statement was published online by the USPSTF on Dec. 14.

Researchers at the University of North Carolina at Chapel Hill Evidence-based Practice Center in Research Triangle Park published a review of the evidence about screening children and adolescents for prediabetes and type 2 diabetes. 

This study included 856 participants from 8 publications. Among the studies reviewed by the researchers, there were no measurable benefits or harms associated with screening.

Several youths with recently diagnosed type 2 diabetes developed renal dysfunction, and 11 even developed diabetic ketoacidosis; the treatment groups did not differ significantly between those taking metformin, metformin plus rosiglitazone, and metformin plus lifestyle changes. 

More participants with metformin plus rosiglitazone presented with minor hypoglycemic events than those taking metformin or metformin plus lifestyle intervention when it came to intervention harms. Study participants taking metformin compared to those on placebo reported more gastrointestinal side effects.

USPSTF concluded that there was not enough evidence to determine the appropriate balance between the benefits and harms of type 2 diabetes screening in children and adolescents. Screening, early detection, and diabetes treatment do not result in known health outcomes.
