Transcriptomic analysis of diabetic kidney disease and neuropathy in mouse models of type 1 and type 2 diabetes.

Diabetic kidney disease (DKD) and diabetic peripheral neuropathy (DPN) are common complications of type 1 (T1D) and type 2 (T2D) diabetes. However, the mechanisms underlying pathogenesis of these complications are unclear. In this study, we optimized a streptozotocin-induced db/+ murine model of T1D and compared it to our established db/db T2D mouse model of the same C57BLKS/J background.

The Impact of Frailty on Patients Undergoing Liver Resection for Colorectal Liver Metastasis.

Background: The aim of this study is to assess the impact of frailty on short-term outcomes after hepatectomy for colorectal liver metastasis (CRLM).

Methods: Patients were identified using the National Surgical Quality Improvement Program (NSQIP). Patients were divided into 3 categories using the 5-item Modified Frailty Index (mFI).

Interleukin-10 Reduces Neurogenic Inflammation and Pain Behavior in a Mouse Model of Type 2 Diabetes.

Purpose: Neurogenic inflammation is a major component of chronic neuropathic pain. Previously, we established the db/db mouse as an animal model of painful diabetic neuropathy (PDN) of type 2 diabetes. In the current study, we investigate the roles of interleukin (IL)-10, an anti-inflammatory cytokine, in the development of neurogenic inflammation and pain behavior in db/db mouse.

Outcomes with Preoperative Biliary Stenting After Pancreaticoduodenectomy In the Modern Era.

Background: Previous studies have documented increased complications following pancreaticoduodenectomy in patients who undergo preoperative biliary stenting (PBS). However, in the modern era, the vast majority of patients with jaundice are stented. We hypothesized that there is no difference in short-term postoperative outcomes between PBS and no PBS in patient with obstructive jaundice undergoing pancreaticoduodenectomy.

Juvenile murine models of prediabetes and type 2 diabetes develop neuropathy.

Peripheral neuropathy (neuropathy) is a common complication of obesity and type 2 diabetes in children and adolescents. To model this complication in mice, 5-week-old male C57BL/6J mice were fed a high-fat diet to induce diet-induced obesity (DIO), a model of prediabetes, and a cohort of these animals was injected with low-dose streptozotocin (STZ) at 12 weeks of age to induce hyperglycemia and type 2 diabetes. Neuropathy assessments at 16, 24 and 36 weeks demonstrated that DIO and DIO-STZ mice displayed decreased motor and sensory nerve conduction velocities as early as 16 weeks, hypoalgesia by 24 weeks and cutaneous nerve fiber loss by 36 weeks, relative to control mice fed a standard diet.
