There is a dearth of evidence to support the omission of metformin during illnesses that may increase the risk of acute kidney injury (AKI), a need that led the current authors to examine the relationship between AKI, lactate concentrations, and risk of lactic acidosis in individuals taking metformin.

Their paper, recently published in the journal 

, reported results of a population-based case control study of metformin use, and lactic acidosis in patients with type 2 diabetes.

The study found a definite association between metformin, lactate accumulation, and the development of lactic acidosis-in fact, individuals treated with metformin were more than twice as likely to develop the condition vs non-metformin treated persons with or without diabetes. The association was strongest in those patients with AKI.

The authors concluded the evidence supports the recommendation to omit metformin in any disease state that may cause acute renal insuffiency.

Guidelines say metformin should be stopped where there is acute kidney injury or risk of renal compromise. Now there is evidence to support those recommendations.

In 2016, the European Society of Endocrinology (ESE), in collaboration with the European Network for the Study of Adrenal Tumors, asserted that adrenal incidentalomas <4 cm and ≤10 Hounsfield units do not require follow-up imaging.

reports results of a study designed specifically to assess the application of the recommended follow up strategies.

The retrospective cohort study looked at clinical characteristics and natural course of incidental adrenal masses in a single center over 13 years in more than 1000 patients.

The authors conclusions helped validate recommendations from the ESE that no follow up imaging is needed for adrenal masses less than 4 cm that have clearly benign features.

A randomized placebo-controlled trial published in the 

examined the effect of probiotics on gestational diabetes.

The trial compared 212 pregnant women between 14 and 16 weeks of gestation who received a lactobacillus probiotic with 211 who did not.

Patients receiving the probiotic had a lower prevalence of gestational diabetes, including women with a previous history. There was also an absence of serious maternal or post-birth adverse events.

The authors stated probiotics may be an inexpensive and safe intervention to combat the prevalence of gestational diabetes.

nurse-guided interventions can improve control of HbA1c in patients with type 2 diabetes.

The study looked at adults with type 2 diabetes and elevated hemoglobin A1c levels. Patients were randomized to standard care, nurse-led education intervention, or nurse-led education plus acceptance therapy.

Nurse-led intervention groups had significant reductions in hemoglobin A1c levels compared with the control group.

When it comes to managing chronic conditions like type 2 diabetes, nurse-led education as an adjunct treatment may make a big difference.

Patients were randomized to standard care, nurse-led education intervention, or nurse-led education plus acceptance therapy.
