Aims: Pemafibrate, a novel selective peroxisome proliferator-activated receptor modulator, was shown to ameliorate lipid abnormalities in a phase III clinical trial of patients with type 2 diabetes mellitus (T2DM). However, its efficacy has not been demonstrated in real-world clinical practice in patients with T2DM.

Methods: We performed a multi-center prospective observational study of the use of pemafibrate in patients with T2DM and hypertriglyceridemia versus conventional therapy, with or without a fibrate.

Sodium-glucose cotransporter 2 inhibitors (SGLT2is) are well-established means of improving glycemia and preventing cardio-renal events in patients with type 2 diabetes. However, their efficacy and safety have yet to be fully characterized in patients with type 1 diabetes (T1D). We studied patients with T1D who regularly attended one of five diabetes centers and treated with an SGLT2i (ipragliflozin or dapagliflozin) for >52 weeks, and the changes in HbA1c, body mass, insulin dose, and laboratory data were retrospectively evaluated and adverse events (AEs) recorded during December 2018 to April 2021.

Aims/introduction: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are used worldwide because of their multiple benefits for patients with type 2 diabetes. The purpose of this study was to determine the efficacy and safety of SGLT2i in patients with type 1 diabetes.

Materials And Methods: Patients with type 1 diabetes who had been treated with SGLT2i for >12 weeks were included in this retrospective observation study.

Background: We compared the effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors on renal function in participants with type 2 diabetes and chronic kidney disease (CKD) classified by degree of albuminuria.

Methods: A retrospective review of the clinical records of Japanese participants with type 2 diabetes (age > 20 years; SGLT2 inhibitor treatment > 2 years; estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m) was conducted.

Aims/introduction: The risk of end-stage kidney disease increases in proportion to the decline in the estimated glomerular filtration rate (eGFR). Although protective effects of sodium-glucose cotransporter 2 inhibitors (SGLT2i) on the eGFR decline were shown in several large-scale clinical trials, there are no studies investigating patients with a high risk of end-stage kidney disease. We investigated the efficacy and safety of SGLT2i in advanced renal dysfunction patients (stage G3 or G4 of chronic kidney disease) with a rapid decline in eGFR.

Intellectual disability (ID) is one of neurodevelopmental disorders characterized by serious defects in both intelligence and adaptive behavior. Although it has been suggested that genetic aberrations associated with the process of cell division underlie ID, the cytological evidence for mitotic defects in actual patient's cells is rarely reported. Here, we report a novel mutation in the STARD9 (also known as KIF16A) gene found in a patient with severe ID, characteristic features, epilepsy, acquired microcephaly, and blindness.
