Acromegaly and Cushing's disease lead to common and distinct comorbidities. Currently available treatments lead to the control of hyper secretion in the majority of cases. However, the prevalence of the comorbidities does not always go back to the one of the normal population after remission. For instance, about 1/3 of acromegalic patients with diabetes and half of patients with Cushing's disease and diabetes will have normal blood glucose values after remission. In contrast, high blood pressure frequently recovers after remission in both diseases...

BACKGROUND: Peroxisome proliferator-activated receptor gamma (PPARγ) is a member of the nuclear receptor superfamily that functions as a ligand-inducible transcription factor. It regulates glucose and lipid metabolism, immunity, and cellular growth and differentiation. Thiazolidinediones (TZDs) are potent insulin sensitizers that function by activating PPARs, with a high specificity for PPARγ. Due to their ability to preserve pancreatic beta cell function and reduce insulin resistance, TZDs have become one of the most prescribed classes of medications for type 2 diabetes (T2D) since their approval by the US Food and Drug Administration (FDA) and initial use in 1997...

High leptin concentration, low-grade inflammation, and insulin resistance often coexist in obese subjects; this adverse metabolic milieu may be the main culprit for increased fracture risk and impaired bone quality seen in patients with type 2 diabetes. We examined the associations of leptin, hs (high sensitivity)- CRP and insulin resistance with bone turnover markers (BTMs) and bone characteristics in 55 young obese adults (median BMI 40 kg/m2) and 65 non-obese controls. Mean age of the subjects was 19.5 ± 2...

There is a growing and alarming prevalence of obesity and the metabolic syndrome in type I diabetic patients (T1DM), particularly in adolescence. In general, low bone mass, higher fracture risk and increased marrow adipose tissue (MAT) are features of diabetic osteopathy in insulin deficient subjects. On the other hand, type 2 diabetes (T2DM) is associated with normal or high bone mass, a greater risk of peripheral fractures and no change in MAT. Therefore, we sought to determine the effect of weight gain on bone turnover in insulin deficient mice...

BACKGROUND: Sclerostin is an inhibitor of the wingless-type mouse mammary tumor virus integration site family/β-catenin signalling pathway (WβcSP), which plays an important role in bone metabolism and in vascular biology. It could act protective regarding atherosclerosis development through its effect on WβcSP in vascular cells. Nevertheless, results of studies analyzing association between circulating sclerostin level (CSL) and atherosclerotic diseases (AD) are showing conflicting results...

Type 2 diabetes mellitus (T2DM) is a chronic, metabolic disease characterized by a lack of insulin and high glucose levels. T2DM can cause bone loss and fracture, thus leading to diabetic osteoporosis. Promoting osteogenic differentiation of osteoblasts may effectively treat diabetic osteoporosis. We previously reported that Sirtuin 1 (Sirt1), a NAD+-dependent deacetylase, promotes osteogenic differentiation through downregulation of peroxisome proliferator-activated receptor (PPAR) gamma. We also found that miR-132 regulates osteogenic differentiation by downregulating Sirt1 in a PPARbeta/δ- dependent manner...

OBJECTIVE: Currently (18)F-2-fluoro-2-deoxy-D-glucose ((18)F-FDG) positron emission tomography/computerized tomography (PET/CT) is being successfully used for staging and follow-up of Hodgkin's lymphoma (HL) and non-Hodgkin's lymphoma (NHL). Various studies have demonstrated that PET/CT effectively detects bone marrow involvement (BMI) and is concordant with bone marrow biopsy (BMB) findings, thus it is deemed as a complementary method. This study was aimed to evaluate(18)F-FDG-PET/CT efficiency for detection of BMI in HL and NHL...

Obesity-related insulin resistance is closely associated with macrophage accumulation and subsequent cytokine release in local tissues. Sirtuin (Sirt) 6 is known to exert an anti-inflammatory function but its role in macrophages in the context of obesity has not been investigated. Here, we generated myeloid-specific Sirt6 knockout mice (mS6KO) and investigated the metabolic characteristics after high-fat diet (HFD) feeding for 16 weeks. Compared with their wild type littermates, HFD-fed mS6KO mice exhibited greater increases in body weight, fasting blood glucose- and insulin-levels, hepatic steatosis, glucose intolerance, and insulin resistance...

In 2017, the management of type 1 diabetes mellitus (T1DM) remains intriguing for the clinician, who has to balance between adequate glycemic control and untoward events related to insulin up-titration. Thus, agents that will complement insulin actions and reduce adverse effects are highly welcome. Areas covered: In this review, the authors summarize results from studies on the sodium glucose co-transporter 2 (SGLT2) inhibitor dapagliflozin in T1DM. Expert opinion: In T1DM, dapagliflozin is associated with significant antihyperglycemic and metabolic properties, which are achieved with reduction or stabilization of insulin dose and with a very low trend for hypoglycemia...

Patients with type 2 diabetes mellitus (T2DM) experience a 1.5-3.5 fold increase in fracture risk, but the mechanisms responsible for these alterations in bone biomechanical properties remain elusive. Macroautophagy, often referred to as autophagy, is regulated by signaling downstream of the insulin receptor. Metabolic changes associated with the progression of glucose intolerance have been shown to alter autophagy in various tissues, but limited information is available in relation to bone cells. The aim of this study was to (a) investigate whether autophagy is altered in bone tissue during impaired glucose tolerance, and (b) determine how autophagy impacts osteoblast differentiation, activity, and maturation...

Most commonly, histologic transformation (HT) from follicular lymphoma (FL) manifests as a diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS). Less frequently, HT may result in a high-grade B-cell lymphoma (HGBL) with MYC and B-cell lymphoma protein 2 (BCL2) and/or BCL6 gene rearrangements, also known as "double-hit" or "triple-hit" lymphomas. In the 2016 revision of the World Health Organization (WHO) classification of lymphoid neoplasms, the category B-cell lymphoma, unclassifiable was eliminated due to its vague criteria and limiting diagnostic benefit...

Diabetes mellitus (DM) is a chronic metabolic disease that gives rise to impaired bone remodeling. Increasing evidences have shown that miRNAs are associated with osteogenic differentiation of stem cells. However, the underlying mechanism that links DM-induced HG conditions and impaired osteogenic differentiation capacity of periodontal ligament stem cells (PDLSCs) still remains unclear. In this study, we found that diabetic mice with increased miR-31 level in periodontal ligaments exhibited greater bone loss...

The inflammation and oxidative stress of bone marrow-derived proangiogenic cells (PACs), also named endothelial progenitor cells, triggered by hyperglycemia contributes significantly to vascular dysfunction. There is supporting evidence that the consumption of red yeast rice (RYR; Monascus purpureus-fermented rice) reduces the vascular complications of diabetes; however, the underlying mechanism remains unclear. This study aimed to elucidate the effects of RYR extract in PACs, focusing particularly on the role of a potent antioxidative enzyme, heme oxygenase-1 (HO-1)...

Philadelphia chromosome-positive acute myeloid leukemia is controversial and difficult to distinguish from the blast phase of chronic myeloid leukemia. As a myeloid neoplasm, rare cases of this leukemia manifest multiple soft-tissue tumors or bone lytic lesions. In this paper, we describe a 49-year-old male patient who had an abrupt onset with sharp chest pain, fever, fatigue, emaciation, and splenomegaly. 18F-fluoro-deoxy-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) result showed diffuse and uneven hypermetabolic lesions in the bone marrow with peripheral bone marrow expansion, multiple soft tissue neoplasms with high 18F-FDG uptake, and lytic bone lesions...

Tendon disorders are frequent both in human and veterinary medicine with high re-injury rates and unsatisfactory therapeutic treatments. Application of naked, chemically-modified mRNA (cmRNA), encoding for therapeutic proteins, is an innovative approach to address tendon healing. In the current study, we demonstrated that injection of naked cmRNA, diluted in a glucose-containing solution, into tendons resulted in high protein expression in healthy and experimentally-injured tendons. Injection of bone morphogenetic protein 7 (BMP-7)-encoding cmRNA resulted in a significantly higher expression of BMP-7 protein and reduced formation of collagen type III, compared to vehicle control...
