BACKGROUND: Diabetes mellitus (DM) is a disorder of glucose metabolism marked by hyperglycemia, glycosuria, hyperlipidemia, negative nitrogen balance and ketonaemia. DM is a major healthcare problems today and its treatment costs billions of dollars worldwide annually. The cases of diabetes have increased rapidly in recent years throughout the world. Currently, for management of type-1 diabetes mellitus (TIDM), multiple daily insulin (MDI) injections is the most popular treatment. Oral administration of insulin is the most suitable and attractive as compared to subcutaneous route but unfortunately cannot be utilized for the administration of peptides and proteins due to poor epithelial permeability and enzymatic degradation within the gastrointestinal tract...

Islet transplantation is a promising alternative therapy for insulin-dependent patients, with the potential to eliminate life-threatening hypoglycemic episodes and secondary complications of long-term diabetes. However, widespread application of this therapy has been limited by inadequate graft function and longevity, in part due to the loss of up to 60% of the graft in the hostile intrahepatic transplant site. We report a proteolytically degradable synthetic hydrogel, functionalized with vasculogenic factors for localized delivery, engineered to deliver islet grafts to extrahepatic transplant sites via in situ gelation under physiological conditions...

Destruction of the insulin-producing β-cells is the key determinant of diabetes mellitus regardless of their types. Due to their anatomical location within the islets of Langerhans scattered throughout the pancreas, it is difficult to monitor β-cell function and mass clinically. To this end, we propose to use a mathematical model of glucose-insulin homeostasis to estimate insulin secretion, glucose uptake by tissues, and hepatic handling of glucose. We applied the mathematical model by Lombarte et al. (2013) to compare various rate constants representing glucose-insulin homeostasis between lean (11% fat)- and high fat diet (HFD; 45% fat)-fed mice...

BACKGROUND: Diabetics with ankle fractures experience more complications than the general population, but it is unclear whether complications differ between type 1 and 2 diabetics and between insulin- and non-insulin-dependent diabetics. This study aims to determine if there is a difference in postoperative complication rates between these groups. METHODS: An administrative health care database from a large commercial insurer was queried to identify operatively treated ankle fractures in patients with type 1 (T1D), type 2 (T2D), type 2 insulin-dependent (T2ID), and type 2 non-insulin-dependent (T2NID) diabetes...

REVIEW
Joachim Denner
The chronic shortage of human transplants to treat tissue and organ failure has led to the development of xenotransplantation, the transplantation of cells, tissues and organs from another species to human recipients. For a number of reasons, pigs are best suited as donor animals. Successful, routine xenotransplantation would have an enormous impact on the health of the human population, including the young, who sometimes require a replacement organ or islet cells, but especially the elderly, who more often suffer the consequences of organ failure...

Obesity and type II diabetes mellitus have contributed to the increase of breast cancer incidence worldwide. High glucose concentration promotes the proliferation of metastatic cells, favoring the activation of the plasminogen/plasmin system, thus contributing to tumor progression. The efficient formation of plasmin is dependent on the binding of plasminogen to the cell surface. We studied the effect of ε-aminocaproic acid (EACA), an inhibitor of the binding of plasminogen to cell surface, on proliferation, migration, invasion, epithelial-mesenchymal transition (EMT), and plasminogen activation system, in metastatic MDA-MB-231 breast cancer cells grown in a high glucose microenvironment and treated with insulin...

Glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) stimulate insulin secretion. They are both released after meal ingestion, and therefore they might cooperate in their actions. However, whether there is a cooperative action of the two incretins is not known. This study therefore investigated the effects on insulin secretion and glucose disappearance of GLP-1 and GIP when given together with intravenous glucose both alone and in combination in mice. Four different doses were used (0...

BACKGROUND: Diabetes mellitus (DM) is well known to increase mortality in several cardiovascular diseases. However, the prognostic impact of DM following transcatheter aortic valve implantation (TAVI) remains controversial. We sought to assess the impact of DM on perioperative (in-hospital or 30-day) complications and mid-term (≥1 year) all-cause mortality after TAVI through meta-analysis. METHODS: A comprehensive literature search of PUBMED and EMBASE was conducted through January 1st 2002 to May 15th 2016...

BACKGROUND: In an experimental animal model of islet transplantation, stable induction of insulin-dependent diabetes mellitus (IDDM) and islet isolation from donor pancreas are essential. Total pancreatectomy for IDDM induction and islet procurement in nonhuman primates leads to unwanted loss of exocrine function and may lead to morbidities associated with IDDM. METHODS: IDDM induction with streptozotocin (STZ) is associated with drug toxicity of STZ and necessitates the killing of another animal for islet procurement...

Zinc oxide (ZnO) is a semiconductor metal oxide nanoparticle with inherent optical properties. Among the different zinc oxide nanostructures, nanoflowers have greater surface area. Utilizing this property a reagentless biosensor has been developed for the detection of beta amyloids, a hallmark of neurodegenerative diseases like Alzheimer's disease, Creutzfeldt-Jakob Syndrome, insulin dependent type II diabetes etc. The poor fluorescence quantum yield and photobleaching effect of Thioflavin T (ThT) upon binding to the model insulin amyloid beta sheets in solution can be overcome by the present engineered biosensor where ThT acts as a target as well as a reporter to detect amyloids adsorbed on a solid template based on ZnO nanoflower...

Scleredema is a deposition disorder which presents as diffuse, symmetric, non-pitting skin induration from dermal deposits of glycosaminoglycans ("mucins"). It classically affects the upper back and posterior neck, often causing skin tightness and decreased range of motion. In most patients the clinical course is chronic and treatment options are limited. We report a case of a patient diagnosed with scleredema associated with longstanding insulin dependent diabetes who was treated successfully with IVIg. Additionally, we have reviewed the literature reporting other patients with scleredema treated with IVIg...

This report describes an unusual case of an insidiously enlarged traumatic palatal perforation after orotracheal intubation in a four-year-old female child with Insulin Dependent Diabetes Mellitus (IDDM). The child was first diagnosed with diabetes at 10 months of age when she was hospitalized for pneumonia. Severe respiratory distress warranted assisted ventilation via orotracheal intubation. Multiple factors namely infection, relative immunodeficiency, poor wound healing, trauma via orotracheal intubation as well as uncontrolled glucose levels, all contributed to the formation and deterioration of the palatal perforation...

Today, care teams within cancer centers encourage patients to be physically active, after diagnosis, based on data obtained mainly from breast, colon and prostate cancer. Intriguingly, the impact of physical activity (PA) on intramuscular tumors (e.g. sarcomas) has not been specifically addressed and, thus, could be mistakenly confounded with other cancers. In this preclinical study we assessed the impact of PA on intramuscular liposarcoma (LS) evolution. Four-week-old nude male mice were active by voluntary running on wheels, for six weeks...

BACKGROUND: Total knee arthroplasty (TKA) is an effective treatment option for patients with advanced osteoarthritis and has become one of the most frequently performed orthopedic procedures. With the increasing prevalence of diabetes mellitus (DM), the burden of its sequela and associated surgical complications has also increased. For these reasons, it is important to understand the association between DM and the rates of perioperative adverse events after TKA. METHODS: A retrospective cohort study was conducted using the American College of Surgeons National Surgical Quality Improvement Program database...
