Maternal type 2 diabetes (T2D) is associated with an increased risk of several pregnancy complications and its prevalence is rising globally. Metformin, an oral medication that is first-line therapy for T2D outside of pregnancy, has the potential to improve glycemic control and reduce insulin requirements, without contributing to maternal hypoglycemia or weight gain. However, it crosses the placenta, and up until recently, very few clinical trials existed that studied its role in T2D pregnancies. Furthermore, concerns exist regarding potential effects of in utero metformin exposure on the offspring in the long-term. In this review we summarize available evidence to date on this topic, propose reasons for heterogeneity across studies, and discuss ongoing gaps in knowledge that will need to be addressed by future research.

An optimal administration approach is critical for effective mRNA delivery and treatment. Nebulizer inhalation offers a mild, convenient, and noninvasive strategy with high translational potential but primarily focused on lung delivery. In this study, we found that surface charges influence tissue targeting of mRNA lipid nanoparticle (mRNA-LNP) postnebulization.

Aims: To determine whether adults with type 2 diabetes (T2D) treated with retatrutide report greater changes in self-reported appetite, dietary restraint, and disinhibition compared to placebo or dulaglutide and to examine associations with weight change.
Materials And Methods: These pre-specified exploratory analyses examined changes from baseline in Appetite Visual Analogue Scale (VAS) and Eating Inventory (EI) scores after 24 and 36 weeks of once-weekly treatment with placebo, dulaglutide 1.5 mg, or retatrutide 0.

Tree-based scan statistics (TBSS) are data mining methods that screen thousands of hierarchically related health outcomes to detect unsuspected adverse drug effects. TBSS traditionally analyze claims data with outcomes defined via diagnosis codes. TBSS have not been previously applied to rich clinical information in Electronic Health Records (EHR).

Aims: Skeletal muscle energetic augmentation might be a mechanism via which intravenous iron improves symptoms in heart failure, but no direct measurement of intrinsic mitochondrial function has been performed to support this notion. This molecular substudy of the FERRIC-HF II trial tested the hypothesis that ferric derisomaltose (FDI) would improve electron transport chain activity, given its high dependence on iron-sulfur clusters which facilitate electron transfer during oxidative phosphorylation.
Methods And Results: Vastus lateralis skeletal muscle biopsies were taken before and 2 weeks after randomization.

Aims: The PARACHUTE-HF trial (NCT04023227) is evaluating the effect of sacubitril/valsartan compared with enalapril on a hierarchical composite of cardiovascular events (cardiovascular death, first heart failure hospitalization), and change in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in participants with heart failure and reduced ejection fraction (HFrEF) caused by chronic Chagas cardiomyopathy (CCC). We describe the baseline characteristics of participants in PARACHUTE-HF compared with prior HFrEF trials.
Methods And Results: PARACHUTE-HF, a multicentre, active-controlled, open-label trial, enrolled 922 participants with confirmed CCC, New York Heart Association (NYHA) functional class II-IV, and left ventricular ejection fraction (LVEF) ≤40%.
