Association of obesity with cardiovascular outcomes in patients with type 2 diabetes and cardiovascular disease: Insights from TECOS.

Background: Obesity is a risk factor for type 2 diabetes (T2D) and cardiovascular disease (CVD). Whether obesity affects outcomes among those with T2D and atherosclerotic CVD (ASCVD) remains uncertain. Our objective was to investigate the relationship between body mass index (BMI) and ASCVD outcomes among TECOS participants with T2D and ASCVD.

Sitagliptin does not reduce the risk of cardiovascular death or hospitalization for heart failure following myocardial infarction in patients with diabetes: observations from TECOS.

Background: To examine the effects of the DPP-4i sitagliptin on CV outcomes during and after incident MI in the Trial Evaluating Cardiovascular Outcomes with Sitagliptin (TECOS).

Methods: TECOS randomized 14,671 participants with type 2 diabetes and atherosclerotic cardiovascular disease (ASCVD) to sitagliptin or placebo, in addition to usual care. For those who had a within-trial MI, we analyzed case fatality, and for those with a nonfatal MI, we examined a composite cardiovascular (CV) outcome (CV death or hospitalization for heart failure [hHF]) by treatment group, using Cox proportional hazards models left-censored at the time of the first within-trial MI, without and with adjustment for potential confounders, in intention-to-treat analyses.

Secondary Prevention of Cardiovascular Disease in Patients With Type 2 Diabetes Mellitus: International Insights From the TECOS Trial (Trial Evaluating Cardiovascular Outcomes With Sitagliptin).

Background: Intensive risk factor modification significantly improves outcomes for patients with diabetes mellitus and cardiovascular disease. However, the degree to which secondary prevention treatment goals are achieved in international clinical practice is unknown.

Methods: Attainment of 5 secondary prevention parameters-aspirin use, lipid control (low-density lipoprotein cholesterol <70 mg/dL or statin therapy), blood pressure control (<140 mm Hg systolic, <90 mm Hg diastolic), angiotensin-converting enzyme inhibitor or angiotensin receptor blocker use, and nonsmoking status-was evaluated among 13 616 patients from 38 countries with diabetes mellitus and known cardiovascular disease at entry into TECOS (Trial Evaluating Cardiovascular Outcomes With Sitagliptin).

Diabetic wound regeneration using heparin-mimetic peptide amphiphile gel in db/db mice.

There is an urgent need for more efficient treatment of chronic wounds in diabetic patients especially with a high risk of leg amputation. Biomaterials capable of presenting extracellular matrix-mimetic signals may assist in the recovery of diabetic wounds by creating a more conducive environment for blood vessel formation and modulating the immune system. In a previous study, we showed that glycosaminoglycan-mimetic peptide nanofibers are able to increase the rate of closure in STZ-induced diabetic rats by induction of angiogenesis.

Effect of lifestyle interventions with or without metformin therapy on serum levels of osteoprotegerin and receptor activator of nuclear factor kappa B ligand in patients with prediabetes.

Osteoprotegerin has been shown to be increased in cardiovascular disorders and type 2 diabetes mellitus. Prediabetes represents a high risk condition for diabetes and diabetic complications. Therefore, we aimed to find the relationship between prediabetes and osteoprotegerin with nuclear factor-B ligand, carotid intima media thickness, and metabolic markers.

The role of BRD7 in embryo development and glucose metabolism.

Bromodomain-containing protein 7 (BRD7) is a member of bromodomain-containing protein family and its function has been implicated in several diseases. We have previously shown that BRD7 plays a role in metabolic processes. However, the effect of BRD7 deficiency in glucose metabolism and its role in in vivo have not been fully revealed.

Evaluation of biomechanical properties of the cornea in patients with primary hyperparathyroidism.

The purpose of this study is to compare the corneal biomechanical properties in primary hyperparathyroid patients and healthy control subjects. The study consisted of 31 patients with primary hyperparathyroidism (study group) and 31 healthy subjects (control group). Corneal biomechanical properties, including corneal hysteresis (CH), corneal resistance factor (CRF), and intraocular pressure (IOP) were measured with an ocular response analyzer (ORA).

Angiogenic Peptide Nanofibers Improve Wound Healing in STZ-Induced Diabetic Rats.

Low expressions of angiogenic growth factors delay the healing of diabetic wounds by interfering with the process of blood vessel formation. Heparin mimetic peptide nanofibers can bind to and enhance production and activity of major angiogenic growth factors, including VEGF. In this study, we showed that heparin mimetic peptide nanofibers can serve as angiogenic scaffolds that allow slow release of growth factors and protect them from degradation, providing a new therapeutic way to accelerate healing of diabetic wounds.

Visceral Obesity Mediates the Association Between Metabolic Syndrome and Obstructive Sleep Apnea Syndrome.

Background: Metabolic syndrome (MetS) and visceral obesity are more prevalent in obstructive sleep apnea syndrome (OSAS). We investigated the association of visceral fat (VF) measures with the components of MetS in OSAS patients with different severity levels, according to World Health Organization (WHO, 1999), National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III, 2001), and International Diabetes Federation (IDF, 2005) definitions.

Patients And Methods: Study population was grouped according to polysomnography results as non-OSAS [who had apnea-hypopnea index (AHI) <5, n = 51], mild OSAS (5 < AHI <15, n = 52), moderate OSAS (15 < AHI <30, n = 53), and severe OSAS (AHI >30, n = 53).

Patient characteristics and statin discontinuation-related factors during treatment of hypercholesterolemia: an observational non-interventional study in patients with statin discontinuation (STAY study).

Objective: The purpose of this study was to identify patient characteristics and statin discontinuation-related factors in patients with hypercholesterolemia.

Methods: A total of 532 patients (age mean±SD: 57.4±11.

Serum heart type fatty acid binding protein levels are not changed in hyperthyroidism.

Background: Heart type fatty acid binding protein (H-FABP) is a small protein and released into the circulation when myocardial damage has occurred. Previous studies have demonstrated that H-FABP is closely associated with cardiac and some endocrinologic disorders including prediabetes, metabolic syndrome, and acromegaly. Hyperthyroism is a well-known disorder associated with cardiovascular diseases.

Role of p97/Valosin-containing protein (VCP) and Jab1/CSN5 in testicular ischaemia-reperfusion injury.

The most significant complication of testicular ischaemia is loss of the testis, which may lead to infertility. Testicular ischaemia damages protein degradation pathways which, together with the overproduction of damaged proteins and consequent upregulation of ubiquitin-conjugated protein aggregates. Despite recent advances, the factors leading to impairment of spermatogenesis owing to testicular ischaemia remain poorly understood.

Role of an endothelin type A receptor antagonist in regulating torsion-induced testicular apoptosis in rats.

Testicular torsion is a well-known medical emergency that can lead to pathological changes in the testicular tissues and male infertility. This investigation was undertaken to gain insight into the effects of an endothelin type A receptor antagonist (BQ123) on torsion-induced germ cell loss. Twenty-eight male Wistar albino rats were divided into four groups.

Virus-like nanostructures for tuning immune response.

Synthetic vaccines utilize viral signatures to trigger immune responses. Although the immune responses raised against the biochemical signatures of viruses are well characterized, the mechanism of how they affect immune response in the context of physical signatures is not well studied. In this work, we investigated the ability of zero- and one-dimensional self-assembled peptide nanostructures carrying unmethylated CpG motifs (signature of viral DNA) for tuning immune response.

[The principles of differentiated thyroid cancer surgery and anesthesia in pregnancy: three case reports].

Development of thyroid nodule during pregnancy is rare, however the cancer rate of this nodule is high. Herein, we present medical outcomes of three pregnant women who were operated with the diagnosis of differentiated thyroid carcinoma in the light of literature. As sonographic findings of three cases showed malignant characteristics, fine needle aspiration biopsy (FNAB) was performed.
