Effect of a culturally adapted behavioral intervention for Latino adults on weight loss over 2 years: a randomized clinical trial.
Identifying effective weight loss interventions for Latino adults at risk of diabetes is of critical public health importance. The purpose of this study was to determine whether a culturally adapted behavioral intervention for Latino adults was more effective than usual care for weight loss over 24 months. The investigators concluded that among Latino adults with high diabetes risk, a culturally adapted behavioral lifestyle intervention was effective for weight loss over 12 months but not 24 months.

Mobile-enhanced peer support for African Americans with Type 2 diabetes: a randomized controlled trial.
This study compared the effectiveness of a community-based diabetes self-management education (DSME) plus mobile health (mHealth)-enhanced peer support intervention to community-based DSME alone for African American adults with poorly controlled type 2 diabetes. This randomized controlled trial took place in Jefferson County, Alabama within a safety-net healthcare system with a group diagnosed with type 2 diabetes and hemoglobin A1C ≥ 7.5%. The intervention group reviewed community-based DSME plus 6 months of mHealth-enhanced peer support, including 12 weekly phone calls, then 3 monthly calls from community health workers. The control group received community based DSME only. Primary outcomes were lower A1C and secondary outcomes were lower diabetes distress, depressive symptoms, self-efficacy or confidence in their ability to manage diabetes, and social support. Of 120 participants selected, 97 completed the study. Both groups experienced clinical meaning reduction in A1C. Participants in the intervention group experienced a significantly larger reduction in diabetes distress compared to the control group.

Implantable cardioverter-defibrillators in heart failure patients with reduced ejection fraction and diabetes.
This study evaluates the effectiveness of a strategy that uses an implantable cardioverter-defibrillator (ICD) plus medical therapy versus medical therapy alone among patients with heart failure (HF) and diabetes. Researchers conducted a patient-level combined-analysis using a combined dataset that included four primary prevention ICD trials of patients with HF or severely reduced ejection fractions. The results indicate that primary prevention ICD in combination with medical therapy versus medical therapy alone was not significantly associated with a reduced risk of all-cause death. The authors conclude that further studies are needed to evaluate the effectiveness of ICDs among patients with diabetes.

The comparative effectiveness of diabetes prevention strategies to reduce postpartum weight retention in women with gestational diabetes mellitus: the gestational diabetes' effects on moms (GEM) cluster randomized controlled trial.
The researchers compared the effectiveness of diabetes prevention strategies addressing postpartum weight retention for women with gestational diabetes mellitus (GDM) delivered at the health system level: mailed recommendations (usual care) versus usual care plus a Diabetes Prevention Program (DPP)-derived lifestyle intervention. They found that a DPP-derived lifestyle intervention modestly reduced postpartum weight retention and increased vigorous-intensity physical activity.

Potentially preventable hospitalizations in Medicare patients with diabetes: a comparison of primary care provided by nurse practitioners versus physicians.
The researchers compared the rates of potentially preventable hospitalizations in older diabetic patients who received primary care from nurse practitioners (NPs) only versus those who received care from primary care physicians only. Using potentially preventable hospitalizations as a quality indicator, they found that primary care provided by NPs was at least comparable with that provided by generalist physicians.

Comparative effectiveness of early versus delayed metformin in the treatment of type 2 diabetes.
The purpose of this study was to quantify the effectiveness of early versus delayed initiation of metformin monotherapy on glycemic control (measured by change in HbA1c) and weight modification (change in body mass index [BMI]). It found that treatment with metformin earlier in the course of type 2 diabetes is associated with better glycemic control, more pronounced weight reduction, and a lower risk for therapy intensification than delayed treatment.

Random blood glucose: a robust risk factor for type 2 diabetes.
This study examined the association between random glucose values and undiagnosed diabetes and prediabetes. In a nationally representative sample of the U.S. population without diagnosed diabetes, the researchers found that a single random blood glucose value of at least 100 mg/dL (5.6 mmol/L) is strongly associated with undiagnosed diabetes and demonstrates a robust dose response.

Long-term outcomes of analogue insulin compared with NPH for patients with type 2 diabetes mellitus.
The researchers compared the effects of neutral protamine Hagedorn (NPH) and long-acting insulin analogues on long-term outcomes. They found no consistent difference in long-term health outcomes when comparing use of long-acting insulin analogues and NPH insulin. The higher cost of analogue insulin without demonstrable clinical benefit raises questions of its cost effectiveness in the treatment of patients with diabetes.

Coadministration of co-trimoxazole with sulfonylureas: hypoglycemia events and pattern of use.
This study assessed the prevalence of coadministration of co-trimoxazole with sulfonylureas and risk of subsequent emergency room (ER) visits for hypoglycemia among older patients with diabetes. It found that the coadministration of co-trimoxazole with sulfonylureas is associated with increased risk of hypoglycemia. Such coadministration is prevalent among older diabetic patients and varies substantially across U.S. geographic regions.

The role of matching when adjusting for baseline differences in the outcome variable of comparative effectiveness studies.
The aim of this study was to evaluate performance of analytical strategies commonly used to adjust for baseline differences in continuous outcome variables for comparative effectiveness studies. It found that with increasing HbA1c baseline differences between groups, bias in effect estimates and suboptimal confidence interval coverage probabilities increased in all approaches. These issues were further compounded by measurement error. Matching on baseline HbA1c, substantially mitigated these issues.

Second-line agents for glycemic control for type 2 diabetes: are newer agents better?
The researchers aimed to assess the benefits and harms of four commonly used antihyperglycemia treatment regimens considering clinical effectiveness, quality of life, and cost. According to the model used by the researchers, all regimens resulted in similar life years and quality-adjusted life years (QALYs) regardless of glycemic control goal, but the regimen with sulfonylurea incurred significantly lower cost per QALY.

Impact of specific glucose-control strategies on microvascular and macrovascular outcomes in 58,000 adults with type 2 diabetes.
This study used comparative effectiveness research methods to compare the effect of four distinct glucose-control strategies on subsequent myocardial infarction and nephropathy in type 2 diabetes. It found that in a large group of adults with type 2 diabetes, more aggressive glucose-control strategies have mixed short-term effects on microvascular complications and do not reduce the myocardial infarction rate over 4 years of follow-up.
