BACKGROUND: Uncontrolled blood glucose impacts key phases of the wound healing process. Various factors have been associated with postoperative wound complications in soft tissue sarcomas; however, the association of postoperative early morning blood glucose with wound complications, if any, remains to be determined. Because blood glucose levels may be modified, understanding whether glucose levels are associated with wound complications has potential therapeutic importance. QUESTIONS/PURPOSES: The purposes of this study were (1) to evaluate if postoperative early morning blood glucose is associated with the development of wound complications in soft tissue sarcomas; (2) to determine a blood glucose cutoff that may be associated with an increased risk of wound complications; and (3) to evaluate if patients with diabetes have higher postoperative blood glucose and an associated increased risk of wound complications...

BACKGROUND: Delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH) is a significant cause of morbidity and mortality. While it is important to detect early signs of DCI, patients with high risk of DCI are difficult to identify, and the potential risk factors are uncertain. This study aimed to identify independent risk factors of DCI and clarify their clinical impact on outcome and the disease course. METHODS: For this nationwide, multicenter, prospective clinical study involving consecutive patients with aSAH recruited from the China National Stroke Registry, demographic, clinical, radiological, and laboratorial data during hospitalisation, in-hospital complications, functional outcomes, and mortality at 3, 6, and 12 months were recorded...

BACKGROUND/AIMS: The main pathogenic mechanism of diabetes is a decrease in the number of islet beta cells or a decline in their function. Recent studies have shown that pancreatic long noncoding RNAs (lncRNAs) have a high degree of tissue specificity and may be involved in the maintenance of islet cells function and the development of diabetes. The aim of this study was to investigate the molecular regulatory mechanism of mouse maternal expressed gene 3 (Meg3) in insulin biosynthesis in pancreatic islets...

Gymnema sylvestre (Retz.) R.Br. ex Sm. (Asclepiadaceae) is a well-known Ayurvedic anti-sweet plant for the treatment of type 2 diabetes mellitus. Although it was previously proposed that G. sylvestre exhibits chemical variation based on geography, most research on G. sylvestre has used material originating from India. Morphological and anatomical descriptions, ITS1-5.8S-ITS2 DNA sequencing, and acid hydrolysis analyses showed that G. sylvestre samples from Vietnam are distinguishable from those of Indian origin and thus suggest a dissimilarity among G...

BACKGROUND AND AIMS: The diagnostic performance of the oscillometric ankle brachial index (ABI) to detect peripheral arterial disease (PAD) varies among populations, suggesting a spectrum effect. When this heterogeneity modifies post-test probabilities, a spectrum bias arises. This study evaluates the presence and influence of spectrum effect and spectrum bias on test performance and clinical decisions. METHODS: Oscillometric and Doppler ABI were compared in two settings: Primary-Care (333 legs) and Vascular-Service (41 legs)...

The fetal origins of health and disease framework has identified extremes in fetal growth and birth weight as factors associated with the lifelong generation of chronic diseases such as obesity, diabetes, cardiovascular disease, and hypertension. Maternal nutrition plays a critical role in fetal and placental development, in part by providing the methyl groups required to establish the fetus's genome structure and function, notably through DNA methylation. The goal of this narrative review is to describe the role of maternal dietary methyl donor (methionine, folate, and choline) and cofactor (zinc and vitamins B2, B6, and B12) intake in one-carbon metabolism and DNA methylation in the fetus and placenta, as well as their impacts on fetal growth and lifelong health outcomes, with specific examples in animals and humans...

Aims: Ischaemic mitral regurgitation (IMR) is consequence of left ventricular (LV) remodelling after myocardial infarction. In some cases, the mitral valve enlarges to compensate for LV remodelling and tenting, improving its coaptation; a process termed 'plasticity'. We sought to identify clinical and echocardiographic factors associated with plasticity in patients with chronic inferior myocardial infarction (CII). Methods and results: This study included 91 revascularized CII patients and 46 controls...

Background: Relatively little is known about the role of phosphatidylserine (PS) in procoagulant activity (PCA) in patients with diabetic kidney disease (DKD). This study was designed to evaluate whether exposed PS on microparticles (MPs) and MP-origin cells were involved in the hypercoagulability in DKD patients. Methods: DKD patients (n = 90) were divided into three groups based on urinary albumin excretion rate, defined as normoalbuminuria (No-A) (<30 mg/24 h), microalbuminuria (Mi-A) (30-299 mg/24 h) or macroalbuminuria (Ma-A) (>300 mg/24 h), and compared with healthy controls (n = 30)...
